It’s an expression of an opinion. But this opinion is based on past experiences and a lot of reading, including some of the practices observed in technology companies such as IBM. “The list of issues is endless and many aspects were covered here last year when lock-downs began at the end of March (UK).”Last week I did a 25-minute video_expressing_my_personal_thoughts on home-working or work-from-home arrangements, having done that (mostly full-time) since 2007. Don’t call it “remote work” or “teleworking”; these misnomers manipulate semantics and twist the narratives so as to harm workers, making it seem like working from one’s own residence is inadequate and thus merits additional deductions, surveillance, a lack of flexibility and so on. One example is, employers tend to wrongly assume that because one’s office is at home they can phone the worker any time of the day. Other common examples are, they expect workers to be productive at any time of the day/week (for no additional or exceptional payment — something most countries mandate), convert “commute time” into unpaid work time, and generally work very long hours under constant wiretapping/ spying, impacting not only the workers but also other tenants, usually loved ones. The list of issues is endless and many aspects were covered here last year when lock-downs began at the end of March (UK). The title of last week’s post was “EPO Home-Working (or ‘Remote’ Working or ‘Teleworking’) Isn’t an Act of Generosity But of Exploitation” and it seems like some workers have been bamboozled/conned into thinking that António_Campinos buying them some ergonomic chair (a tiny fraction of the annual salary of EPO examiners) makes it acceptable for him to take away lots of benefitd. Don’t be grateful for it; António has ideas and now that fewer people are in the Office they_approach_low-cost_labourers_further_abroad (outside Austria, Germany, and the Netherlands). Like Greek_mythology_teaches_us, the oversized wooden horse isn’t quite the gift which it’s disguised as. That ergonomic chair too is easily discardable. “My advice to EPO staff representatives is, stay constantly vigilant.”Earlier today the EPO’s Central Staff Committee (CSC) circulated this_document [PDF] and a member of staff ‘leaked’ it to us. The document isn’t exceptionally interesting and it concerns a meeting that took place 13.5 days ago, i.e. nearly a fortnight ago. The gist (or the abstract) says: “On 18 October, the administration provided us with a copy of a draft Circular defining a mid-term teleworking policy for the Office (see CA/38/21, page 17) as of 1 February 2022 and to be reviewed in no later than 3 years after entry into force. This Circular would replace both the Emergency Teleworking Guidelines in place since March 2020 and the revised Part-Time Home Working (PTHW) Guidelines in place since May 2018. Management invited us ["the staff representation"] to a meeting which took place on 22 October.” Page 2 describes location limitations. In page 1 it gives the example of “EPO employee recruited in Munich or Berlin would be allowed to reside in Hamburg and to telework from there. In addition to the employee’s residence, an employee can telework from any location within the country of employment.” This is just Germany shielding its economic interests in the Office. Obviously most workers are based in Germany, so they’re force to stay there and spend money there. For some, this means sending the kids to highly expensive international schools. My reflex or my instinct about all this, having observed the tricks leveraged by Benoît_Battistelli, isn’t positive at all. They’re trying to sell this ‘reform’ using “pandemic”, even though it actually predates the pandemic, as noted in this document. They did the same with the SAP, based on a lie, and we’ve already seen how they misuse the pandemic to outsource_'courts'_to American_companies, not just to the outskirts (Haar). It’s unconstitutional, it is in violation of the EPC (respectively), but what do these people care/worry about? It took ILO-AT nearly_an_entire_decades_to_assess_"Strike_Regulations", which were unlawful all along. I’m not being facetious and I’m not being negative for the sake of ‘bashing’ the EPO. I’ve been working from home for over 14 years (incidentally, this site turns 15 in a matter of days). I saw how such working conditions are exploited as a sort of pretext for paycuts (or a lack of pay increases, which as long as we have positive inflation rates means a paycut). My advice to EPO staff representatives is, stay constantly vigilant. Try to envision the next step of the administration or the proposals floated behind closed doors; these people absolutely do not care about patent examiners and they do not even understand them (or their jobs)! Letting people work from home is just a matter of complying with the national laws — to the most minimal extent in this case — while squeezing out the most “production” out of workers… in a time of international emergency/crisis. █ ⣿⡇⢠⣤⣼⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡿⣿⢛⣿⢛⣻⣿⡛⢻⣿⣻⣏⠛⢻⣭⣀⡀⢀⣠⣤⡀⢠⣄⢠⡄⣽⣻⣿⣿⡄⡟⣿⡟⣿⡟⣿⣿⡟⣿⣿⡟⣿⣿⣛⢿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⠀⠀⠀⠀⠀⠀ ⣿⢣⣿⣿⣟⡛⢋⡙⣿⣿⣿⣿⣿⣿⣿⣿⣧⢿⣿⡟⢸⣿⢹⣿⢸⣿⣿⡇⠀⢸⣿⢹⣿⢸⣿⢹⣿⢸⣿⣼⡇⠛⠉⣿⡏⠁⡇⣿⣷⣿⡇⣿⣏⡁⣿⣏⡁⣿⡏⣿⡇⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⠀⠀⠀⠀⠀⠀

Schestowitz Part I Video_download_link | md5sum 0128b92f33ce424432b6f7032fd552da http://techrights.org/videos/san-marino-epo-part1.webm Part II Video_download_link | md5sum 38fc442ae91368960cb3b887da960604 http://techrights.org/videos/san-marino-epo-part2.webm Summary: San Marino has moved on from one diarchy (Roman Emperor and the Pope) to another diarchy (Benoît_Battistelli and Jesper Kongstad) and now it’s yet another diarchy (António_Campinos and Stalin as EPO rubber-stamper), partly because of a former EPO examiner (nearly 2 decades) who wished to advance his career in the private sector and then became a rubber-stamper of Battistelli, in effect crushing former colleagues THE above video is split into two due to technical issues; it deals with Part 30, which may be followed by a bit of a break (before embarking on parts 31- 35). As already alluded to in the latest meme ("Bilateral_Battistelli"), nations can be easily bribed — and the smaller the nations, the cheaper the bribe — in order to get unlawful proposals rubber-stamped. This is a severe problem, which is further exacerbated by small nations with hardly any European Patents (sometimes zero). It’s quite revealing that the_German_government_prefers_to look_away, pretending not to see the gross abuse. The same can be said about mainstream media in Germany. One might be inclined to interpret that as an endorsement of the corruption or acceptance of crime. “It’s quite revealing that the German government prefers to look away, pretending not to see the gross abuse.”Either way, some nations did not vote in favour of the illegal “Strike Regulation”, so the series will end on a more positive note. We’ve meanwhile republished this_paper which covers some of the points raised in the videos. There seems to be absolutely no oversight at the EPO. Even tribunals_have_been_reduced_to_theatrics. What’s left of the so- called ‘media’ (JUVE, Managing IP etc. as of a few days ago regarding the decision_on_co-called_'ViCo') plays along with the theatrics because such media is funded (compromised) by those looking to financially gain from endless expansion of the EPO’s authority and patent scope. █ 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇Bakels_paper⦈_

YOU ARE HERE ☞ San Marino and the Perfidious Betrayal of Liberty 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇Silvia_Rossi_and_Bruno_Cinquantini⦈_ Silvia Rossi and Bruno Cinquantini, the delegates from San Marino, were guilty of a shameful betrayal of the principle of “Libertas” at the EPO. Summary: San Marino took a payment from the notorious Battistelli just months after approving an unlawful_proposal from him; the payment to San Marino was authorised on the very same occasion (136th meeting of the Administrative Council) as these unlawful “Strike Regulations” being rubber-stamped, which makes it seem like a potential bribe previously endowed also to Cyprus, Greece, Italy, Malta, and Monaco (the snapshot at the bottom also shows Lithuania and some financial figures) Finally, we come to the Most_Serene_Republic_of_San_Marino, a landlocked enclave situated close to the city of Rimini on the Adriatic coast of Italy. San Marino lays claim to being the oldest extant sovereign state, as well as the oldest constitutional republic. More recently, it has acquired a rather unsavoury reputation as a tax_haven_and_hub_for_money_laundering. San Marino acceded to the European Patent Convention on 1 July 2009. “San Marino acceded to the European Patent Convention on 1 July 2009.”In June 2013, its delegation on the EPO’s Administrative Council was headed by Silvia Rossi who has presided over the State Office for Patents and Trademarks since January 2006. Rossi’s deputy was the Italian patent attorney, Bruno_Cinquantini. Cinquantini was born in Blera, Italy, in 1953 and he graduated from the University of Pisa where he studied aircraft engineering. He joined the EPO in 1980 as an examiner of patents at grade A1 assigned to The Hague branch office. He transferred to the EPO’s Munich head office on 1 September 1984 and to its branch office in Vienna on 17 January 1992. In February 1996 he returned to Munich as a principal administrator at grade A4. “He joined the EPO in 1980 as an examiner of patents at grade A1 assigned to The Hague branch office. He transferred to the EPO’s Munich head office on 1 September 1984 and to its branch office in Vienna on 17 January 1992. In February 1996 he returned to Munich as a principal administrator at grade A4.”While serving in the EPO office in Vienna, Cinquantini lived either in the city or on the outskirts. However, he retained his flat in Munich and with one exception his sons attended the European School there. For a brief period during 1992-93, his wife and second son lived in Blera, and the boy went to school there. By 1993 his wife and three sons were together again in Munich, and they lived in his flat there until he himself returned in 1996. After returning to Munich, Cinquantini submitted a request to the EPO for an “installation allowance” connected with his relocation from Vienna. He also requested an additional “installation allowance” for his family, falsely claiming that his wife and three dependent children had taken up residence in Munich on 1 March 1996. Shortly thereafter, Cinquantini moved into a bigger apartment in Munich with his family. It seems that he planned to cover the costs of this move with the “installation allowance” payments that he hoped to obtain from the EPO. The EPO granted Cinquantini a basic “installation allowance” for himself in respect of his relocation from Vienna. This is normal practice when an official transfers his or her place of employment from one EPO duty station to another. However, the additional claim to an allowance for his family members was rejected on the grounds that they had stayed on at the same address in Munich while he had been serving in Vienna. The aggrieved Cinquantini proceeded to bring a complaint before the ILOAT in Geneva. The case was decided by Judgment_No._1820 delivered on 28 January 1999 (local copy [PDF]). The Tribunal found Cinquantini’s pleas for “a more liberal construction” of the applicable rules to be “unconvincing” and it dismissed his complaint as “utterly devoid of merit”. “When San Marino made its debut on the Administrative Council of the European Patent Organisation in October 2009, Cinquantini mysteriously appeared as its deputy head of delegation, a position which he has held ever since.”Some time later in the same year, Cinquantini left the EPO. It is not clear whether his departure was due to “sour grapes” over his failure to obtain the additional “installation allowance” for his family, or whether there were other reasons behind it. In any case, he embarked on a new career as an “IP consultant” with the prominent Italian law firm, Notarbartolo_&_Gervasi. When San Marino made its debut on the Administrative Council of the European Patent Organisation in October 2009, Cinquantini mysteriously appeared as its deputy head of delegation, a position which he has held ever since. His official title is “Advisor to the Secretariat of State for Industry, Handcraft and Commerce”. 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇Bruno_Cinquantini,_Silvia_Rossi,_and_Marco_Arzilli⦈_ Bruno Cinquantini (l.) and Silvia Rossi (c.) with Secretary of State Marco Arzilli (r.). Like the other EPO micro-states, the role of San Marino in “le système Battistelli” was very much that of a “captured state”. In this regard, it’s worth noting that the agenda of the 136th Meeting of the Administrative Council included a request from Benoît_Battistelli to the Council to grant him a mandate to conclude a bilateral agreement with San Marino. “Like the other EPO micro-states, the role of San Marino in “le système Battistelli” was very much that of a “captured state”.”The preface of the relevant proposal document – CA/54/13 (warning: epo.org link) – notes that similar agreements had already been concluded with Cyprus, Greece, Italy, Malta and Monaco. Now it was San Marino’s turn, and the Council agreed to the proposal submitted by Battistelli in CA/54/13. We shall keep this_local_copy [PDF] as the original will vanish one day. A few months after Rossi and Cinquantini had played their part in rubber- stamping the “Strike Regulations”, their supervising minister, Marco Arzilli was invited to Munich for the “honour” of signing of a bilateral agreement with EPO President Benoît Battistelli in October_2013: (warning: epo.org link) “This is a very important signature for the San Marino business world, and a step forward for innovation and development,” said Minister Arzilli. … Thanks to this agreement with the EPO, the Republic of San Marino can be on an equal footing with other European countries with regards to the possibility to innovate and enter new markets.” 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇Arzilli_with_Battistelli⦈_ San Marino Secretary of State Arzilli signing a bilateral agreement with Battistelli in October 2013. By a curious irony, the national coat of arms of San Marino bears the Latin motto “Libertas” (“Liberty”). This is supposed to refer to the last words of the state’s reputed founder St. Marinus: “Relinquo vos liberos ab utroque homine” (Translation: “I leave you free from both men”, referring to the Roman Emperor and the Pope). Unfortunately, the San Marino delegates on the EPO’s Administrative Council did little to ease the burden of EPO employees languishing under the yoke of the EPO’s corrupt and tyrannical diarchy, composed of EPO President Benoît Battistelli and his "protector" Jesper Kongstad. 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇Battistelli-Kongstad_diarchy⦈_ The San Marino delegation betrayed the guiding principle of “Libertas” by acquiescing in the corrupt and oppressive tyranny of the Battistelli-Kongstad diarchy. As a matter of fact, by endorsing Battistelli’s “Strike Regulations”, Rossi and Cinquantini helped to trample on the fundamental rights of EPO staff. “As a matter of fact, by endorsing Battistelli’s “Strike Regulations”, Rossi and Cinquantini helped to trample on the fundamental rights of EPO staff.”Indeed, it is no exaggeration to say that they betrayed the cause of “Libertas”, which is supposed to be the guiding principle of the “Most Serene Republic” that they purported to represent. Cinquantini’s complicity in this affair was particularly perfidious in view of the fact that he had previously worked at the EPO for almost two decades between 1980 and 1999. The fundamental rights of his former colleagues were clearly of no consequence to this shameless opportunist. 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇Bruno_Cinquantini⦈_ Bruno Cinquantini’s opportunistic sell-out of his former colleagues at the EPO was particularly perfidious. Rossi and Cinquantini continue to represent San Marino on the EPO’s Administrative Council to this day. So far, they have not been called to account for their actions in June 2013, nor are they ever likely to be. “In the upcoming parts, we plan to look at these abstentionist delegations in more detail.”That concludes our in-depth look at the Administrative Council delegations which voted in favour of Battistelli’s “Strike Regulations” in June 2013. As we previously_noted, no delegation had sufficient integrity and moral courage to vote against Battistelli’s egregiously flawed proposal. However, seven delegations withheld their support by abstaining.

11.02.21⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▂▃▄▅▆▇█ ⌧ Gemini_version_available_♊︎ ✐ Bright_Future_for_Alternatives_to_the_World_Wide_Web⠀✐ Posted in Site_News at 7:04 pm by Dr. Roy Schestowitz Summary: Awareness of — and of course interest in — Gemini Protocol (gemini:// ) is growing; as we approach our 16th year it’ll be interesting to see how much of a role this Internet protocol will play Yesterday some Linuxy site wrote an introduction to Gemini Protocol, which was cited_earlier_today_by_Linux_Today. The word spreads fast as the number of capsules continues_to_grow, as does the size of our capsule, which is still listed first as follows (moments_ago): 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇Capsule_count_for_November⦈_ Two days ago the total was 1,727 and today it’s 1,750. I’m aware of some capsules not listed there, so the list is incomplete to say the least. Maybe there are 3,000 capsules out there. Maybe more… some aren’t always online, so the count is subjective. Smaller capsules are harder to find and detect; Lupa is the work of only one man, Stéphane_Bortzmeyer. The Web has gone too far. More people recognise this. The World_Wide_Web Consortium is captured. This means we need something other than the Web. 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇techrights age⦈ The whole thing about alternatives to the Web excites us because we’ve long worried about how bloated the Web became, requiring even more bloated (‘Web’) browsers to access/navigate. Complete with plug-ins, DRM (EME), JavaScript and other nasty stuff. Some people already try to ‘extend’ the alternative protocol (examples from the past two days can be seen here and here, but replies are dismissive; there’s desire to keep things very simple). Speaking of simplicity, we still use the same theme that we used in 2006. No joking! Same theme. “Speaking of simplicity, we still use the same theme that we used in 2006.”This coming Sunday we officially turn 15. Our Internet domain (not limited to the Web) has subsites too. gemini.techrights.org is a growing priority and we constantly make improvements to it (it’s not very visible when one faces the constraints of Gemini). We’re about to exceed 38,000 pages in total inside the capsule (it’ll happen some time before we turn 15), so there’s another cause for celebration. In terms of number of blog posts, later this month we’ll exceed 32,000 in total. █ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

You’ll_soon_be_able_to_easily_run_multiple_Linux_containers on_Chromebooks [Ed: Better yet, replace ChromeOS with an OS that does not spy on you]⠀⇛ I’ve been running Linux containers on Chromebooks since the feature first appeared in beta about 3 years ago and it has changed the way I use my Chromebook. With this feature, I was able to use a Chromebook for undergraduate Computer Science classes, for example. And I now use it for similar classes at the Masters level. [...] By choosing the extra containers option, you’ll be able to create or delete additional Linux containers, start or stop the VMs where the Linux instances are running, and more. As I read it, you should also be able to assign different colors to different Linux containers as well. So you could have different containers for Debian, Arch, or some other Linux distributions. This experimental, still-in-the-works feature will be disabled by default at first. To use it, you’ll need to enable the crostini-multi-container flag in chrome://flags. Note that the current code says the flag is called “crotini”. I assume that’s a typo, so I’ve corrected it above. o § Server⠀➾ # ⚓ China_Has_Already_Reached_Exascale_–_On_Two_Separate Systems⠀⇛ Native CPU and accelerator architectures that have been in play on China’s previous large systems have been stepped up to make China first to exascale on two fronts. The National Supercomputing Center in Wuxi is set to unveil some striking news based on quantum simulation results on a forthcoming homegrown Sunway supercomputer. The news is notable not just for the calculations, but the possible architecture and sheer scale of the new machine. And of course, all of this is notable because the United States and China are in a global semiconductor arms race and that changes the nature of how we traditionally compare global supercomputing might. We have been contemplating China’s long road to datacenter compute independence, of which HPC is but one workload, and these are some big steps. # ⚓ Nokia_deploys_SR_Linux_and_data_center_switches_for everyWAN_for_service_expansion_and_capacity_| MarketScreener⠀⇛ Nokia today announced it is providing its SR Linux network operating system (NOS) and 7220 IXR data center switches to everyWAN, the Spanish operator that provides national and international IP transit and interconnection services between major data centers and internet peering points in Europe. The solution will enable everyWAN to expand its services and data center operations by improving network scalability, while helping operations objectives with more granular network visibility and NetOps automation. # ⚓ Sara_Assicurazioni:_Transforming_the_Insurance_Industry with_Kubernetes_|_SUSE_Communities⠀⇛ “In SUSE Rancher we can standardize all our images and create a new container in a matter of seconds — it’s extremely easy.” Paolo Perrucci, Head of Infrastructure, Sara Assicurazioni. # ⚓ What_is_a_Homelab_and_Why_Should_You_Have_One?⠀⇛ n case you have never hear the term, Homelab is the name given to a server (or multiple server setup) that resides locally in your home and where you host several applications and virtualized systems for testing and developing or for home and functional usage. This server can be a simple tower or small PC or a Raspberry Pi like device or a repurposed professional server that you can acquire from companies who discard them due to their age but are still usable. In my case, I have a small ITX case with a Core i5, 8 GB RAM, 2 TB of hard disk. This is a very modest machine but enough for my usage which is merely for home purposes. o § Audiocasts/Shows⠀➾ # ⚓ KDE_Telegram_Client?_Meet_TOK!_–_Kockatoo_Tube⠀⇛ # ⚓ Destination_Linux_250:_We’re_Experiencing_Some_Ennuicastr⠀⇛ This week’s episode of Destination Linux, we have an interview with the developer of Ennuicastr (“On we caster”) an open-source podcast, vodcast, interview multi-track recording tool. Then we’re going to discuss Samsung’s latest innovation powered by Linux and KDE Connect is now available for iPhone users. Plus we’ve also got our famous tips, tricks and software picks. All of this and so much more this week on Destination Linux. So whether you’re brand new to Linux and open source or a guru of sudo. This is the podcast for you. [...] [Tito] doesn’t seem to mention it in the video below, but we’re assuming the dock component of this project is just a 3D printed box with a connector sticking up for the GBA SP’s link cable port, since that’s where the TV-out modification outputs its video. Incidentally that means you don’t really need the dock itself, but it certainly looks cool. At the end of the video [Tito] goes over a few of the rough edges of the current build, including the rather lengthy pairing process to get the Joy-Cons talking to the Raspberry Pi. But ultimately, he says that not only does the system feel good in his hands, but playing those classic games on the big screen has been a nice change of pace. # ⚓ Chromium_is_NOT_free_software._–_Invidious⠀⇛ o § Kernel Space⠀➾ # ⚓ Linux_Kernel_5.15_Released,_Here_Are_the_Top_3_New Features⠀⇛ Linus Torvalds has announced the release of kernel 5.15. The release offers a huge plus in the form of a new NTFS driver, especially for cross-platform data exchange with other systems. Above all, Linux Kernel 5.15 is a significant milestone in that it’s also a Long Term Support (LTS) kernel to be maintained for at least the next five years and also is a huge kernel update in general with many new features. # ⚓ folio-5.16⠀⇛ “Add memory folios, a new type to represent either order-0 pages or the head page of a compound page. This should be enough infrastructure to support filesystems converting from pages to folios. The point of all this churn is to allow filesystems and the page cache to manage memory in larger chunks than PAGE_SIZE. The original plan was to use compound pages like THP does, but I ran into problems with some functions expecting only a head page while others expect the precise page containing a particular byte. The folio type allows a function to declare that it’s expecting only a head page. Almost incidentally, this allows us to remove various calls to VM_BUG_ON(PageTail(page)) and compound_head(). This converts just parts of the core MM and the page cache. For 5.17, we intend to convert various filesystems (XFS and AFS are ready; other filesystems may make it) and also convert more of the MM and page cache to folios. For 5.18, multi-page folios should be ready. The multi-page folios offer some improvement to some workloads. The 80% win is real, but appears to be an artificial benchmark (postgres startup, which isn’t a serious workload). Real workloads (eg building the kernel, running postgres in a steady state, etc) seem to benefit between 0-10%. I haven’t heard of any performance losses as a result of this series. Nobody has done any serious performance tuning; I imagine that tweaking the readahead algorithm could provide some more interesting wins. There are also other places where we could choose to create large folios and currently do not, such as writes that are larger than PAGE_SIZE. I’d like to thank all my reviewers who’ve offered review/ack tags: Christoph Hellwig, David Howells, Jan Kara, Jeff Layton, Johannes Weiner, Kirill A. Shutemov, Michal Hocko, Mike Rapoport, Vlastimil Babka, William Kucharski, Yu Zhao and Zi Yan. I’d also like to thank those who gave feedback I incorporated but haven’t offered up review tags for this part of the series: Nick Piggin, Mel Gorman, Ming Lei, Darrick Wong, Ted Ts’o, John Hubbard, Hugh Dickins, and probably a few others who I forget” # ⚓ Memory_Folios_Merged_For_Linux_5.16_–_Phoronix⠀⇛ The proposed memory “folios” functionality for Linux 5.16 is happening! This low-level change to the Linux memory management code was merged today for this next kernel. With memory folios not having landed for Linux 5.15 and lack of comment recently by Linus Torvalds on the matter, it wasn’t clear if he was going to take in this latest folios pull request. But to some surprise, right away today he pulled in the initial folios code for Linux 5.16. # ⚓ Folios_merged_for_5.16_[LWN.net]⠀⇛ The long-running and sometimes acrimonious discussion on the memory folio patch set has come to an end: the folio patches were the first thing pulled into the mainline repository for the 5.16 development cycle. Now the developers involved just have to do all of the other work identified as necessary to clean up the memory-management subsystem and isolate it from other parts of the kernel. # ⚓ Linux_5.15_LTS_release_–_Main_Changes,_Arm,_RISC-V_and_MIPS architectures⠀⇛ Released around two months ago, Linux 5.14 added support for Raspberry Pi 400 keyboard computer, merged the core scheduling functionality, removed the old IDE block drivers, improved support for Intel Alder Lake processors, and more. Linux 5.15 will be an LTS kernel getting long-term support for at least 2 years, and possibly more, if companies extensively use the new kernel and request a longer support period up to 6 years like for Linux 5.10 or Linux 5.4 for instance. # ⚓ Linux_5.15_just_arrived_–_and_here’s_what’s_inside [Ed: In its coverage of a Linux relase ZDNet filled the first two paragraphs with Microsoft propaganda, basically painting "Linux" using Microsoft's brush; it's so gross.]⠀⇛ Linux 5.15 also addressed the introduction of - Werror — a move endorsed by Torvalds to force developers to fix bugs earlier. It was intended to be a new default behavior for kernel builds that treated all compiler and configuration “warnings” as “errors” that must be fixed. -Werror however was met with opposition from kernel developers and led to Torvalds partially backtracking on the effort. # ⚓ Intel_AMX_Support_Lands_For_Linux_5.16_–_Phoronix⠀⇛ After going through a number of rounds of patch revisions over the past year, Intel’s kernel-side changes for supporting Advanced Matrix Extensions (AMX) with next-gen Xeon Scalable “Sapphire Rapids” processors has landed for Linux 5.16! Intel was quick to land the initial AMX changes into the LLVM compiler and GCC compiler while getting the kernel-side bits squared away is what took more than one year but now in mainline, months ahead of Sapphire Rapids’ ramp in Q2. # ⚓ Btrfs_With_Linux_5.16_Seeing_More_Performance Optimizations,_NVMe_ZNS_–_Phoronix⠀⇛ The Btrfs file-system continues seeing new performance optimizations and other work, thanks in part to the renewed interest around the file-system with Fedora Workstation continuing to use it by default along with openSUSE and other Linux distributions. On the busy first day of the Linux 5.16 merge window the Btrfs changes were submitted by maitainer David Sterba of SUSE. There are performance improvements, some new feature work, and the usual assortment of fixes and code maintenance. # ⚓ Linux_5.16_Networking_Changes_Are_Quite_Busy_From_New Drivers_To_Intel_100G_Improvements_–_Phoronix⠀⇛ Given the wide range of hardware running Linux and especially Linux being dominant in the data center, the networking changes each kernel cycle remain quite vibrant. Linux 5.16 is no exception with the main feature pull sent in on Monday for all the networking updates. One of the new drivers this cycle is the Realtek RTW89 WiFi driver for supporting the Realtek 8852AE 802.11ax adapters and future models. o § Benchmarks⠀➾ # ⚓ Beelink_U59_Review_–_Windows_11,_Ubuntu_on_a_Jasper_Lake mini_PC⠀⇛ o § Applications⠀➾ # ⚓ Music_Radar_–_music_recognition_application⠀⇛ Shazam is an app that identifies multimedia. The program stores a catalogue of audio fingerprints in a database. Shazam works by analyzing the captured sound and seeking a match based on an acoustic fingerprint in a database of millions of songs. It generates a spectrogram (a time/frequency 2D graph of the sound, with amplitude at intersections) of the sound, and maps out the frequency peaks from it (which should match key points of the harmonics of voice or of certain instruments). Shazam can identify music, movies, advertising, and television shows, based on a short sample played either through the microphone of the device and also when you’re listening through your headphones. Unfortunately it’s proprietary software. As the software is developed by Apple it isn’t available for Linux. However, this doesn’t stop enterprising open source developers from making their own creations. o § Instructionals/Technical⠀➾ # ⚓ 30_Nmap_Examples⠀⇛ This tutorial shows 30 Nmap usage examples, related to subjects which were explained in previous articles published at Linux Hint. Examples include from host discovery to vulnerability audit, network diagnostics and more. Most of them were produced in real or simulated scenarios making them real valuable for network administrators or students. Implementing the examples described in this tutorial is pretty simple, as running a command. # ⚓ 4_ways_to_edit_photos_on_the_Linux_command_line⠀⇛ Linux is useful to photographers and graphic artists. It provides many tools for editing different types of image files and formats, including photographs. This roundup shows that you do not even need a graphical interface to work with your photos. Here are four ways that you can edit images at the command line. # ⚓ Use_the_Linux_cowsay_command_for_a_colorful_holiday greeting_|_Opensource.com⠀⇛ You may have heard of a small program that takes input, such as a message that you type, and outputs a picture of a cow quoting your message. It is called cowsay. It has been written about before here on Opensource.com. So, to have a little fun with it, I thought I’d use it to celebrate Día de los Muertos (Day of the Dead). # ⚓ Install_Squid_Proxy_Server_on_Rocky_Linux_8_and_AlmaLinux_8 –_LinuxStoney⠀⇛ Squid is a caching and forwarding HTTP web proxy. Squid has a lot of features, and it is used in variety of situations such as speeding up web server by caching repeated requests, caching web and dns lookups, filtering traffic, blocking websites, etc. It is written in C++ and distributed under GNU GPL license. Squid is considered as the most reliable content control software and has been used by many organizations since last 2 decades. In this article, we are installing Squid proxy server on Rocky Linux 8 or AlmaLinux 8. Although, there are too many similar articles already available on the web. But we write this article to include the minor (but important) steps, that are usually overlooked by the other writers. This article is strongly emphasizes on the installation and initial configuration of the Squid proxy server on Rocky Linux 8 or AlmaLinux 8. Therefore, if you are willing to configure some advance settings in Squid proxy then we strongly recommend you to purchase Squid Proxy Server 3.1: Beginner’s Guide by Packt Publishing. # ⚓ Can_now_switch_between_pulseaudio_and_pipewire⠀⇛ Continuing with setting up pipewire, previous blog post: https://bkhome.org/news/202111/initial-setup-of- pipewire.html Pipewire is working, until I connected a bluetooth speaker. Bluetooth mouse connected and worked, but the bluetooth speaker connected, but no sound. Pipewire is completely new to me, so it is probably just a configuration setting somewhere. I already had to make one change, turn on bluez5 in the pipewire default module loading, as explained in the Gentoo wiki: https://wiki.gentoo.org/wiki/PipeWire …that change, and the bt speaker connected, but no joy with sound. # ⚓ ExplainShell:_A_Web-Based_Alternative_to_the_Traditional Linux_Man_Pages⠀⇛ No matter how experienced you’re with the Linux command line, there will always be times when you’ll encounter unfamiliar commands. In such situations, while the natural instinct is to either refer to man pages or google the command to figure out what it does, what if we tell you there’s a better (read immersive) way to do it. Well, as it turns out, there’s a tool called ExplainShell that does exactly that: tells you what each part of a shell command does in an easy-to- comprehend manner. So let’s dive in to check out ExplainShell in detail. # ⚓ Pi_IoT_In_Python_Using_Linux_Drivers_–_I2C⠀⇛ I2C is an important interface for many devices and Linux has a driver that means that you can use it worrying about the exact details of the hardware – if you know how. # ⚓ Searching_through_compressed_files_on_Linux_|_Network World⠀⇛ There are quite a few ways to search through compressed text files on Linux systems without having to uncompress them first. Depending on the format of the files, you can choose to view entire files, extract specific text, navigate through file contents searching for content of interest, and sometimes even edit content. I # ⚓ help2man_and_subcommands⠀⇛ help2man is quite nice for autogenerating manpages from command line help, making sure that they stay up to date as command line options evolve. It works quite well, except for commands with subcommands, like Python programs that use argparse’s add_subparser. # ⚓ Upgrade_to_Debian_11_from_Debian_10_–_Unixcop_the_Unix_/ Linux_the_admins_deams⠀⇛ Hello friends. Debian is one of the most used operating systems by sysadmins worldwide. This is because Debian is one of the best in stability and community support that making it ideal for all types of projects from the biggest to the smallest. Recently Debian 11 has seen the light of day, which makes many people wonder about the need to leap Debian 10. Well, that is exactly what we are going to explain to you because, in this post, you will learn how to upgrade to Debian 11 from Debian 10. # ⚓ Configure_VCS_on_CentOS_8_|_RHEL_8_step_by_step_–_Unixcop the_Unix_/_Linux_the_admins_deams⠀⇛ Here we explain how to configure the VCS Veritas Cluster Server (New name InfoScale) three node cluster on CentOS 8/RHEL 8 step by step for high- availability server. We already Installed VCS, visit how to install veritas cluster server # ⚓ How_to_Install_Linux_Kernel_5.15_on_Ubuntu_20.04_– LinuxCapable⠀⇛ Linux kernel 5.15 is out with many new features, support, and security. The Linux 5.15 kernel release further improves the support for AMD CPUs and GPUs, Intel’s 12th Gen CPUs, and brings new features like NTFS3, KSMBD (CIFS/SMB3), and further Apple M1 support, amongst many other changes and additions. In the following tutorial, you will learn how to install the latest 5.15 Linux Kernel on Ubuntu 20.04 LTS Focal Fossa. # ⚓ Pacemaker_with_DRBD_MariaDB_Server_-⠀⇛ There are many forms of high availability, replication, and resilience in the face of various types of failure. For example, you can make the MariaDB Server work in an active/passive setup, such that the passive node can recover persistent messages written to the disk on the active node should the active node fail. While MariaDB Server is supported clustering is intended to facilitate scalability. Cluster if a node fails queues on the failed node are lost. However, with the high availability setup described in this tutorial. When a node fails, the durable persistent messages can be recovered by a different node. # ⚓ How_to_Install_GNOME_41_Desktop_on_Ubuntu_20.04_– LinuxCapable⠀⇛ GNOME 41 introduces many changes from visual changes, new apps, and overhaul back-end changes to improve performance. Overall, it is a solid upgrade from GNOME 40 with introductions of a new remote desktop client called Connections, new mobile settings, improved multi-tasking, improved UI, and back-end performance, amongst many other additions.

Here in this guide, we give you the step- by-step instructions on how to upgrade to Fedora 35 from Fedora 34 via GUI and CLI method. # ⚓ Chromium_Blog:_Searching,_browsing,_and_shutdown_Chrome performance_improvements⠀⇛ You’ve probably noticed that potential queries are suggested to you as you type when you’re searching the web using Chrome’s omnibox (as long as the “Autocomplete searches and URLs” feature is turned on in Chrome settings.) This makes searching for information faster and easier, as you don’t have to type in the entire search query — once you’ve entered enough text for the suggestion to be the one you want, you can quickly select it. # ⚓ How_To_Install_XFCE_Desktop_on_Linux_Mint_20_–_idroot⠀⇛ In this tutorial, we will show you how to install XFCE Desktop on Linux Mint 20. For those of you who didn’t know, Xfce is a lightweight desktop environment for UNIX-like operating systems. The XFCE desktop uses fewer resources (Memory and CPU) than the other desktops and is also comparatively stable. If you have Cinnamon or the MATE desktop running on your system, you can still install and switch to the XFCE desktop in Linux Mint. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of an XFCE Desktop on a Linux Mint 20 (Ulyana). # ⚓ How_to_Install_CUDA_on_Ubuntu_20.04⠀⇛ CUDA is a parallel computing platform and a programming model that provides a remarkable user experience when leveraging GPU for everyday general-purpose computing. CUDA stands for Compute Unified Device Architecture. It is created by NVIDIA. CUDA comprises the CUDA toolkit ( compiler, profile, and debugger ), the software driver, and the CUDA SDK. The software layer gives direct access to the GPU’s virtual instruction set and parallel computational elements. For deep learning researches and framework developers use cuDNN for high-performance GPU acceleration. It is a library of primitives for deep neural networks. In this guide, we learn how to install CUDA and CuDNN on Ubuntu 20.04. There are two ways of going about this. You can install CUDA from Ubuntu Repository – which is the easiest approach – or install from the CUDA repository which provides the latest version of CUDA. # ⚓ How_to_Manage_KVM_Virtual_Machines_with_Cockpit_Web Console⠀⇛ In a previous topic, we walked you through how create and manage KVM machines on command line. For command-line enthusiasts, this is an ideal way of creating and keeping tabs on virtual machines. For those who prefer using a graphical display, the Cockpit utility comes very much in handy. Cockpit is a free and opensource web-based GUI that allows you to easily monitor and administer various aspects of your Linux server. It is lightweight, and resource-friendly and does not gobble up resources and neither does it reinvent subsystems or add its own tooling layer. It’s purely an on- demand service and uses your normal system login credentials. # ⚓ How_to_install_Mysql_Server_8_on_OpenSUSE_Leap_15.3⠀⇛ MySQL is an open-source relational database management system. Its one of the popular relational management system. Mysql is commonly installed as part of the popular LAMP or LEMP (Linux, Apache/Nginx, MySQL/MariaDB, PHP/Python/Perl) stack. It implements the relational model and Structured Query Language (SQL) to manage and query data. o § Games⠀➾ # ⚓ Steam_Play_compatibility_tool_Luxtorpeda_gets_controller support,_new_tooling_|_GamingOnLinux⠀⇛ Luxtorpeda is a Steam Play compatibility tool (like Proton) that allows you to run games from Steam using various different game engines and reimplementations. The basic idea is that Luxtorpeda manages various Linux-native game engines for you. So you go to download a game on Steam, like Warzone 2100 or Arx Fatalis and instead of giving you the old and crusty versions Steam has it will give you the currently up to date open source game engines. There’s a lot it supports and the Luxtorpeda website was updated to make browsing what it supports easier. # ⚓ Godot_Engine_–_Animation_Data_Rework_for_4.0⠀⇛ One of the last areas pending for redesign in upcoming Godot 4.0 has now been completed, resulting in much improved usability when dealing animation data. # ⚓ Growbot_is_a_beautiful_and_thoughtful_adventure_about_a little_robot_in_a_space_garden_|_GamingOnLinux⠀⇛ Point and click adventure game fans have quite the treat released recently with Growbot, an adventure set aboard a space station full of strange plants and aliens. Developed by Wabisabi Play and published by Application Systems Heidelberg, it has some truly excellent artwork that helps suck you into the world. “Growbot is a 2D point-and-click adventure set upon a beautiful biopunk space station. You play as Nara, a growbot in training to become a captain. When your station home is attacked by rapidly growing crystals, it’s down to you to save it. # ⚓ The_wonderful_Mutazione_gets_a_free_epilogue_in_the_Penpal Update_|_GamingOnLinux⠀⇛ Have you played Mutazione yet? If not, you’re mad. It’s probably one of the nicest indie games to release in 2019 and then come to Linux officially in 2020. Developer Die Gute Fabrik, and publisher Akupara Games released this free update to celebrate the second anniversary of the IGF award- winning title Mutazione. # ⚓ Linux_Remains_Above_1%_on_the_Steam_Hardware_Survey [Ed: Measuring the number of GNU/Linux users by proportion of Gamers with DRM who are on GNU/Linux is like measuring average population sizes by surveying a playground]⠀⇛ The Steam on Linux market-share has been slowly but surely climbing since Valve introduced Steam Play as their Proton based solution for running Windows games on Linux. If you’re at all interested in gaming on PCs, you’ve probably come across Steam, Valve’s platform for distributing, updating and running games. Steam makes it possible to purchase a game, install it over the internet and then run it from the Steam interface. There are plenty of Steam games that will run on Linux. This approach is officially supported by Steam using a system called Proton, which is a compatibility layer that allows Windows games to run on Linux-based operating systems. # ⚓ Steam_On_Linux_Marketshare_Hits_New_Multi-Year_High,_AMD Powering_~40%_Of_Linux_Gaming_Systems_–_Phoronix⠀⇛ Back in July Steam on Linux re-crossed the 1.0% marketshare threshold following the announcement of the Steam Deck and continued progress around Steam Play / Proton. The Steam on Linux user-base has continued growing month by month and has hit another high with the numbers published today that cover the month of October. According to the new survey results, Linux now commands a 1.13% marketshare on Steam, a 0.11% increase compared to September. This is a larger number than normal for Linux and assuming no revisions are made, it’s likely the result of more gamers and developers trying out Linux / Steam Play ahead of Steam Deck units beginning to ship to consumers later this quarter. The Steam Deck announcement has certainly rejuvenated interest in Linux gaming and especially with Steam Play running an increasing number of modern Windows games with ease, especially now with EAC, CEG, and other DRM technologies working more nicely with Linux. # ⚓ Linux_has_now_seen_6_months_of_being_above_1%_on_the_Steam Hardware_Survey_|_GamingOnLinux⠀⇛ Something magical appears to be happening on Steam. Not only is Linux above 1% for another month but we’ve now seen 4 months of it continuing to rise. Going by our own historical stats, this makes it the highest it has been for over 3 years too. # ⚓ Proton_Experimental_gets_more_CEG_DRM_fixes,_new_fsync_code |_GamingOnLinux⠀⇛ Recently Valve upgraded Proton Experimental, the special version of Proton that pulls in advancements first with support for their older CEG DRM and another new build is up. In the changelog it simply notes that it improves “compatibility with games using CEG DRM” but it also has the latest fsync changes for the newer code. According to a Proton developer if you have an older Kernel fsync should be automatically disabled so if you want to use it you need to update. # ⚓ Chill-out_and_sort_through_your_room_in_the_zen-puzzler Unpacking_out_now_|_GamingOnLinux⠀⇛ Unpacking is an oddly satisfying game. It’s a chilled-out zen-puzzler where you get items from boxes and place them around various rooms. Developed by Witch Beam, it’s very much the opposite of their previous chaotic game Assault Android Cactus+. I hate moving. Really, I do. I’ve moved many times over the last 10 years and it got pretty irritating but Unpacking manages to make it relaxing. Can’t quite put my finger on why either. Just seeing everything eventually get put into the right place, it gives a nice calm feeling that they were clearly going for. # ⚓ Apogee_Entertainment_gets_another_remaster_out_with_Monster Bash_HD_|_GamingOnLinux⠀⇛ Originally released back in the ’90s, Monster Bash HD is a fresh remaster from Apogee Entertainment and Emberheart Games and it’s available for Linux. Continuing their work to upgrade games following Crystal Caves HD and Secret Agent HD, sounds like it won’t be their last either. One of the most challenging games of its time returns, with touch-ups like new environmental effects, smoother and improved gameplay, and support for modern resolutions. Preserving the classic while giving it a new life for new and old players alike. o § Desktop Environments/WMs⠀➾ # § GNOME Desktop/GTK⠀➾ # ⚓ Announcing_Solanum⠀⇛ A little while ago I released version 3.0.0 of my app Solanum. When doing the release, I realized something: I never announced the app here. Woops. So, here is the announcement. Solanum is an app that lets you work in timed sessions with regular breaks, based on the Pomodoro Technique. By default work sessions are 25 minutes, short breaks are 5 minutes, and long breaks are 15 minutes, and you work 4 sessions before a long break. These defaults can be configured in the Preferences window from Solanum 3.0.0 onward. o § Distributions⠀➾ # § New Releases⠀➾ # ⚓ Linux_Release_Roundup_#21.44:_Microsoft_Edge_Stable, Calibre_5.31,_EasyOS_3.1,_and_More_Releases⠀⇛ Tresquel [sic] GNU+Linux is a Ubuntu-based distribution that doesn’t make use of proprietary software as much as possible. The latest release is not a huge update but brings much-needed security fixes. You can know more by checking out their official release notes. # § PCLinuxOS/Mageia/Mandriva/OpenMandriva Family⠀➾ # ⚓ Firefox_Browser_»_PCLinuxOS⠀⇛ Firefox is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. Updated to 94.0. # § SUSE/OpenSUSE⠀➾ # ⚓ Leap’s_First_Quarterly_Update_is_Released⠀⇛ The release manager for openSUSE Leap has announced the release of the first quarterly iso image update for the 15.3 release Dubbed as respins, these updates refresh the iso images based on General Availability (GA) release and contain all the updates for the past quarter. “The openSUSE release team has over time received quite some requests to provide regular refreshes of install media,” wrote release manager Lubos Kocman in an email to the project. “Some of these 15.X requests date back to the 15.2 development cycle.” # § IBM/Red Hat/Fedora⠀➾ # ⚓ Red_Hat_OpenShift_and_other_solutions_behind_customer and_partner_success_stories⠀⇛ Each month, we highlight how customers have found success with Red Hat products and solutions on the blog. Our partner ecosystem is behind many customer success stories, and partners are driving open source innovation within their geographical regions as well as the global community. In this post, we’re featuring an Argentina- based company and the Red Hat products that have helped it modernize services for customers in the United States, Europe and beyond. We also have the opportunity to feature how Red Hat solutions are helping fuel customer success for two partners—a technology provider that’s helping its customers in Ireland, and worldwide, achieve business success, and a gaming market pioneer that’s revolutionizing trillion-dollar industries such as transportation, healthcare and manufacturing. # ⚓ RedHat_celebrates_Halloween_by_relaunching_version 0.9_of_its_system_–_itsfoss.net⠀⇛ Red Hat has made the decision to celebrate Halloween by recalling and relaunching version 0.9 of its system, which was published on October 31, 1994. That release was a paid beta and the first version of the system to be distributed publicly, so It is considered the starting gun for what is currently the leading Linux company , both in terms of economics and technological leadership. The fact that Red Hat 0.9 was launched on October 31, 1994 earned it, of course, the nickname of ‘Halloween’, and is that the day and month indicated are the date to celebrate the well-known festival of pagan roots, which has become increasingly popular due to the preponderance of English-speaking countries in global culture. # ⚓ Debug_memory_errors_with_Valgrind_and_GDB⠀⇛ Buffer overflows, memory leaks, and similar memory issues plague many C and C++ programs. Valgrind is a sophisticated utility for finding low-level programming errors, particularly involving memory use. The GNU Project Debugger (GDB), is a popular tool for use with C/C++ and other languages. This article explains how to use Valgrind and GDB together along with vgdb, a small program that serves as an intermediary between Valgrind and GDB. We’ll debug a simple program containing various intentional bugs to demonstrate the combined usage of Valgrind, GDB, and vgdb. This buggy program writes to invalid memory, uses an uninitialized variable, and leaks memory. We will see how to combine Valgrind, GDB, and vgdb to find each of these bugs. # ⚓ IT_leadership:_3_training_tips_|_The_Enterprisers Project⠀⇛ Are your IT managers better at managing technology than they are at leading their teams? If your organization is like many IT groups, then your honest answer is probably a solid “Yes.” In most IT organizations, the best tech leads are promoted into management positions because they are good at managing technologies. But once they are in a management role, many new leaders struggle to provide effective leadership, and team productivity and morale often suffer as a result. Once you and your managers agree on what performance changes need to happen, use the following three tips to provide more effective leadership training. # ⚓ Build_a_lab_in_36_seconds,_run_Podman_on_a_Mac,_and more_tips_for_sysadmins [Ed: Most of the picks here are just IBM products if not vendor lock-in (if support is available for other distros, not controlled by Red Hat/ IBM, it tends to be lacking, second-class)]⠀⇛ # ⚓ How_to_provision_AWS_infrastructure_with_Ansible⠀⇛ Infrastructure as Code (IaC) is a method to provision and manage infrastructure and other resources using declarative definition files or code. Instead of manually configuring the servers (physical or virtual) and network devices (and other resources), you can use IaC to manage the entire infrastructure lifecycle. Ansible is one of the best IaC tools, and this article explains how to use it to provision infrastructure and other resources in a public cloud. # ⚓ CIO_role:_Why_the_first_90_days_are_crucial⠀⇛ Imagine a boat leaving a port and sailing across the ocean. If the boat’s path is off course by just one degree when it leaves, after 90 days, it will be so far off course that it will never reach its intended destination. On the other hand, if the boat stays true to course early on, minor variations later in the journey can be course-corrected more easily. The same concept applies to the first 90 days on any job – but it’s especially important when you’re taking on the CIO role. Your first 90 days will determine whether you become a trusted senior executive in the organization or a technology manager who’s seen as merely “keeping the lights on” and fixing IT problems. This three-month window is the only time you can create this impression. If you fall down into the operational depths during this time, there is little chance you’ll be able to elevate yourself in the eyes of the organization and your peers in the coming months and years. Conversely, if you establish yourself in these three months as a senior leader with vision and strategy at the forefront, you will be elevating yourself to the level any CIO needs to operate at to be effective in an organization. # ⚓ Digital_transformation:_4_common_beliefs_to reconsider⠀⇛ If you weren’t familiar with digital transformation before the pandemic, you certainly are now. When employees, executives, and customers across every industry and vertical were forced inside, organizations around the world adjusted rapidly to accommodate the limitations of a digital environment. Though physically more disconnected than ever, digital connections exploded as we all found new ways to reach clients, collaborate with coworkers, and do virtually everything else from home. The idea of top-down organizational change isn’t new, however. It’s been around for decades as a natural response to changes in technology and culture. Though business leaders across the globe have tried – and sometimes failed – to implement company-wide change, there is no one-size-fits-all approach to transformation. Here are four long-held beliefs about digital transformation that could hinder your change strategy. # ⚓ Fedora_35_Linux-based_operating_system_available_for download_with_GNOME_41⠀⇛ Today is the day many of us have been waiting for — Fedora 35 is officially here! Yes, folks, you can download the operating system immediately. For many Linux users, Fedora is considered the best distribution based on the open source kernel. Why? Because Fedora focuses on truly free and open source software — a pure Linux experience. It is also fairly bleeding edge, while at the same time, remaining stable enough for daily use. What makes Fedora 35 exciting? This version operating system uses the brand-new GNOME 41 as its default desktop environment. GNOME 41 is notable for having significant performance improvements when using Wayland. Speaking of Wayland, Fedora 35 Beta will run faster when using it with an NVIDIA GPU. Plus, version 35 Beta gets NVIDIA with XWayland, for an improved experience when using apps that aren’t designed for Wayland. # ⚓ Fedora_35_Released_with_GNOME_41,_Improved_PipeWire Experience⠀⇛ Yes, I know: this is not technically Ubuntu related, but I do like to report on events from outside the orange bubble from time to time — heck, I really should get around to doing something with omglinux.com, shouldn’t I?. Plus, I use Fedora regularly in order to keep tabs on GNOME development. So what’s new in Fedora 35? # ⚓ Fedora_Linux_35_Released_with_GNOME_41,_Fedora Kinoite_Flavor,_and_WirePlumber⠀⇛ After six months of hard work, Fedora Linux 35 is here with the latest and greatest GNOME 41 desktop environment for the Fedora Workstation edition. GNOME 41 brings some cool new features, such as a redesigned GNOME Software package manager that gives you instant access to Flatpak apps from the Flathub repository, a new GNOME Connections app for remote desktop access, and new settings for multitasking # ⚓ Fedora_Linux_35_Released_As_Another_Exciting, Feature-Packed_Update⠀⇛ Fedora 35 is now officially available today as the latest major release of this Linux distribution developed by Red Hat and the open-source community. Fedora 35 is another very rich feature update at the forefront of Linux innovations from servers to the desktop. Fedora 35 as usual ships with bleeding-edge packages and other new features Red Hat engineers developed for respective upstream projects from the Linux kernel to GNOME. Fedora Workstation 35 is using GNOME 41 by default, features all of the latest (X)Wayland improvements including support around NVIDIA’s proprietary driver, and also has other updated desktops available. # ⚓ What’s_new_in_Fedora_Workstation_35⠀⇛ Fedora Workstation 35 is the latest release of the Fedora Project’s free desktop operating system. It includes some new features and many tune-ups to the user experience. You can get Fedora Workstation 35 now from the official website, or upgrade your existing install using GNOME Software or through the terminal with dnf system-upgrade. This article describes some of the major improvements included in Fedora Workstation 35. # ⚓ Worth_the_wait:_Fedora_Linux_35_is_here!⠀⇛ Today, I’m excited to share the results of the hard work of thousands of Fedora Project contributors: our latest release, Fedora Linux 35, is here! While we broke our six- release streak of on-schedule releases, we felt it was more important to resolve a few outstanding blocking bugs. Fedora believes that software has to be usable to be useful, so while we know that a predictable schedule is important, we also ensure that every release meets our criteria, no matter what the calendar says. # ⚓ Ben_Williams:_F34-20211101_Updated_isos_Released⠀⇛ The Fedora Respins SIG is pleased to announce the latest release of Updated F34-2021101- Live ISOs, carrying the 5.14-14-200 kernel. This is the Final Set of Fedora 34 updated isos. This set of updated isos will save considerable amounts of updates after install. ((for new installs.)(New installs of Workstation have about 1GB of updates savings )). A huge thank you goes out to irc nicks: dbristow, dowdle, geraldosimiao, Southern_Gentlem for testing these iso. # § Debian Family⠀➾ # ⚓ Systemd-free_antiX_21_Release_Brings_in_Debian_11 “Bullseye”_as_its_base_With_New_Applications⠀⇛ AntiX, a popular Debian-based distro for users not wanting Systemd, has just announced its version 21 release. This release brings a couple of improvements, most notably using Debian 11 as a base, alongside updated apps and kernels. Before we start, it should be noted that AntiX uses SysVinit, instead of the much more popular Systemd. This means that it may not be ideal for beginners. With that out of the way, let’s look at some of the exciting changes in AntiX 21! # ⚓ Lightweight_antiX_21_Linux_Distribution_Released⠀⇛ Published release of lightweight Live- distribution AntiX 21 , optimized for installation on outdated hardware. The release is based on the Debian 11 package base, but comes without the systemd system manager and with eudev instead of udev. You can choose to use runit or sysvinit for initialization. The default user environment is created using the IceWM window manager. ZzzFM and ROX-Filer are available to work with files. # § Canonical/Ubuntu Family⠀➾ # ⚓ Ubuntu_optimised_for_Intel_processors_accelerates adoption_of_IoT_innovations⠀⇛ Canonical published the first Ubuntu images optimised for the next generation of Intel IoT platforms, which address the unique requirements of the intelligent edge across multiple industry verticals. Both companies are dedicated to enabling on Ubuntu the Intel IoT platforms’ specific features such as real-time performance, manageability, security, and functional safety, as well as allowing users to take advantage of their improved CPU and graphics performance. The collaboration ensures that developers and enterprises can create reliable and secure devices, bring their products to market faster, and benefit from up to 10 years of commercial Ubuntu support. # ⚓ Canonical_Begins_Offering_Ubuntu_Images_Optimized_For Intel_CPUs⠀⇛ Canonical has begun publishing Ubuntu install images that are optimized for use on next- generation Intel IoT platforms. Canonical with cooperation from Intel is beginning to publish ISO images of Ubuntu Core 20 and Ubuntu 20.04 LTS desktop that are optimized for Intel Atom X6000E series / Pentium / Celeron N / Celeron J processors (Elkhart Lake) as well as Intel 11th Gen Core processors. # ⚓ Canonical_releases_Ubuntu_images_optimised_for_Intel IoT_devices⠀⇛ # ⚓ Top_7_Reasons_To_Use_Ubuntu_|_Itsubuntu.com⠀⇛ Ubuntu is a free desktop operating system that is easy to access, install, and customize. It is made for computers, smartphones, and network servers, and it is compatible with many types of modern sophisticated software. In addition to it, Ubuntu comes with lots of benefits that make it an operating system of choice for many users worldwide. In this article, we have explained some of them. # ⚓ IPFire_2.27_–_Core_Update_161_available_for_testing⠀⇛ A new update is available for testing: IPFire 2.27 – Core Update 161. It comes with a huge performance improvement for the Intrusion Prevention System which allows it to deliver excellent throughput even on smaller hardware. On top of that come a brand new kernel and various security and bug fixes. Please note, that this update will reconnect any PPP connections and we recommend performing a reboot after the update has been installed. # ⚓ Ubuntu_Fridge_|_Ubuntu_Weekly_Newsletter_Issue_707⠀⇛ Welcome to the Ubuntu Weekly Newsletter, Issue 707 for the week of October 24 – 30, 2021. # ⚓ Ubuntu_22.04_LTS_Begins_its_Development,_Download_and Test_Now._–_LinuxStoney⠀⇛ Shortly after the release of the stable version of Ubuntu 21.10, Canonical developers began developing the next release of the Ubuntu 22.04 distribution with long-term support. The new Ubuntu 22.04 LTS was code- named Jammy Jellyfish. In addition to publishing the development cycle schedule, developer Steve Langasek also provided some details about upcoming software package updates in his report. With Ubuntu 22.04 comes support for Python 3.10 and finally the transition to the current version of OpenSSL 3.0. The desktop environment could most likely be GNOME 42, which would allow Ubuntu to catch up with GNOME again and always offer its users the latest version. As part of the updates, PHP 8.1 or Ruby 3.0 should also be added, while the GCC compiler collection will probably remain in the latest version 11, as GCC 12 has a scheduled release date in April (April) next year. o § Devices/Embedded⠀➾ # ⚓ Expandable_Tiger_Lake_DIN-railer_serves_up_2.5GbE_with TSN⠀⇛ UK based Impulse Embedded has launched Advantech’s UNO-148, a compact, expandable DIN-rail industrial computer and IoT gateway that features Intel’s 11th Gen Tiger Lake ULP processors. The system is also available from some other distributors (see end of story) but is listed as “new” by Advantech. Designed for industrial applications including factory automation, traffic management, and robotics control, the UNO-148 follows other UNO- branded systems such as the 8th Gen Whiskey Lake based UNO-238. # ⚓ Commell_unveils_first_Tiger_Lake-H_SBCs⠀⇛ Commell unveiled 3.5-inch “LE-37P” SBC and Mini-ITX “LV-6713” SBCs featuring Intel’s powerful 11th Gen H-series Core and Xeon-W CPUs. The LE-37P offers 2.5GbE, GbE, 7x USB 3.2 Gen2, 2x SATA, DP and HDMI, and 3x M.2. Commell often goes months at a time without a product announcement before touching down with one of the first SBCs built around Intel’s latest Core CPUs. The Taiwanese firm has done it again with announcements of 3.5-inch LE-37P and full-size Mini-ITX LV-6713 SBCs, which appear to be the first SBCs to feature Intel’s desktop-class, 11th Gen Tiger Lake-H. There is no guarantee they will be the first to ship, but when you can announce a product with this level of detail it usually means you are near the front of the line. # ⚓ 3.5-inch_i.MX8M_SBC_provides_optional_serial_expansion cards⠀⇛ Avalue’s 3.5-inch “RSC-IMX8M” SBC runs Linux or Android on an i.MX8M with up to 2GB DDR4, 8GB eMMC, 2x GbE, 2x USB 3.0, HDMI, MIPI-DSI/CSI, 2x M.2, and optional serial expansion. Avalue has launched its first product based on NXP’s i.MX8 family of system-on-chips with a 3.5- inch board that offers an up to quad-core i.MX8M. Previous 3.5-inch SBCs from Avalue include the Intel Elkhart Lake powered ECM-EHL, among others. Other 3.5-inch boards based on the i.MX8M include Seco’s SBC-C20, and i.MX8M SBCs using other form factors include Boundary Devices’ Nitrogen8M, Arrow’s 96Boards CE Extended Thor96, SolidRun’s HummingBoard Pulse, and the armStone MX8M from F&S. # ⚓ Building_a_Bicycle_Dash_Cam_With_Advanced_Capabilites⠀⇛ The original setup relies on a Raspberry Pi 3, which takes a photo every 10 seconds using the attached Pi Camera. It then processes these photos using OpenALPR, which is a piece of software for reading licence plates. Licence plates detected while cycling can be stored on the Raspberry Pi for later, something which could be useful in the event of an accident. # § Open Hardware/Modding⠀➾ # ⚓ The_Pi_Zero_2_W_Is_The_Most_Efficient_Pi_|_Hackaday⠀⇛ Last week we saw the announcement of the new Raspberry Pi Zero 2 W, which is basically an improved quad-core version of the Pi Zero — more comparable in speed to the Pi 3B+, but in the smaller Zero form factor. One remarkable aspect of the board is the Raspberry-designed RP3A0 system-in-package, which includes the four CPUs and 512 MB of RAM all on the same chip. While 512 MB of memory is not extravagant by today’s standards, it’s workable. But this custom chip has a secret: it lets the board run on reasonably low power. # ⚓ Raspberry_Pi_Zero_2_W_vs_Radxa_Zero_–_Features_and benchmarks_comparison_–_CNX_Software⠀⇛ The just-announced Raspberry Pi Zero 2 W is not the first quad-core Arm SBC following Raspberry Pi Zero form factor, and back in 2017, the Banana Pi BPI-M2 Zero was introduced for $15, and the Radxa Zero was unveiled last June with an Amlogic S905Y2 SoC with price starting at $15 as well. With its Allwinner H2+ quad-core Cortex-A7 processor clocked at 1 GHz and a price bumped up to $23, the Banana Pi M2 Zero has mostly become irrelevant, but the Radxa Zero may still be considered by some people with a 1.8 GHz processor, and options for up to 4GB RAM, so let’s see how features compare against Raspberry Pi Zero 2 W, followed by some benchmark numbers. # ⚓ Scale_up_your_dragon_costume_with_wings_that_extend, flap_and_retract_|_Arduino_Blog⠀⇛ This year for Halloween, Quint BUILDs wanted to make something special for his daughter’s costume. Quint’s idea was to design and fabricate a pair of mechatronic dragon wings that can mount to a user’s back and move in three different modes by utilizing a set of pneumatic air cylinders. The prototype began as a single air cylinder connected to a relay that was, in turn, controlled by a single Arduino Micro and button. This way, Quint could finely tune the timings and pressures required for the device. After 3D printing a simple controller, machining a few aluminum plates, and welding it all together into a second prototype, it was time to experiment with programming more complex movements. # ⚓ YouTuber_Shane_Wighton_built_a_robot_that_paints murals_|_Arduino_Blog⠀⇛ Driven by a desire to print massive pieces of art on his new studio’s blank wall, Shane Wighton of the YouTube channel Stuff Made Here set out to create a large painting robot, which he calls “Janksy” after the famous artist and the jankiness of the construction. In principle, the device works by using a large gantry that spans the entire length of the wall to move horizontally whilst a series of cables and pulleys move it vertically. To avoid vibrations caused by moving such a large amount of weight so quickly, a second and far smaller/faster gantry houses a spray nozzle that deposits paint dots. All of this hardware is controlled by an Arduino Uno that translates positional commands into movements for the onboard stepper motors and servo. # § Mobile Systems/Mobile Applications⠀➾ # ⚓ New_Galaxy_S21_Android_12_One_UI_4.0_beta_rolling_out with_lots_of_bug_fixes!_–_SamMobile⠀⇛ # ⚓ Android_12_Theming_System_–_A_Swing_And_A_Miss⠀⇛ # ⚓ Android_12′s_new_background_app_limitations_could_be a_major_headache_for_power_users⠀⇛ # ⚓ How_to_Unlock_the_Bootloader_on_Your_Android_Device⠀⇛ # ⚓ Gamasutra_–_Press_Releases-_Check_the_store,_Android gamers,_a_sweet_surprise_is_waiting_for_you!⠀⇛ # ⚓ Stealthy_Trojan_that_roots_Android_devices_makes_its way_on_app_stores_|_CSO_Online⠀⇛ # ⚓ LG_built_an_infotainment_system_based_on_Android Automotive_–_9to5Google⠀⇛ # ⚓ Android_Users_Need_to_Uninstall_These_151_Apps Immediately_|_PCMag⠀⇛ # ⚓ Tablet_shipments_have_started_to_drop_again_in_time for_Android_12L_–_SlashGear⠀⇛ # ⚓ Samsung_One_UI_4.0_(Android_12)_update_tracker: Eligible_devices_&_more⠀⇛ # ⚓ Android_12′s_broken_casting_volume_issue_will_be fixed_in_Android_12L⠀⇛ # ⚓ How_To_View_Your_Notification_History_In_Android_12⠀⇛ # ⚓ Android_November_patch_fixes_actively_exploited kernel_bug⠀⇛ # ⚓ Google_just_banned_150_dangerous_Android_apps,_so delete_them_from_your_phone⠀⇛ # ⚓ Xiaomi_Black_Shark_4S_Pro_is_the_most_powerful Android_smartphone_(for_now)_–_PhoneArena⠀⇛ # ⚓ Moto_E40_Review:_Only_for_Android_Purists_on_a Budget?_|_NDTV_Gadgets_360⠀⇛ # ⚓ Android_12L_Update:_Everything_You_Need_to_Know_| Digital_Trends⠀⇛ # ⚓ Android_12:_Everything_you_need_to_know_|_Android Central⠀⇛ # ⚓ Galaxy_Z_Fold_3_gets_a_taste_of_Android_12_in_new beta_–_9to5Google⠀⇛ # ⚓ Hands-On_With_Android_12L⠀⇛ # ⚓ Samsung_Android_12_Tracker:_Here_are_all_the_official One_UI_4.0_beta_builds_to_download_and_install⠀⇛ # ⚓ Will_The_OnePlus_9_/_9_Pro_Get_Android_12_Update?⠀⇛ # ⚓ You_can_fix_Android_12′s_mistake_and_add_smart_home controls_back_to_the_power_menu_with_Tasker⠀⇛ # ⚓ Unverified_App_Links_On_Android_12_Will_Always_Open In_The_Browser ⠀⇛ # ⚓ How_To_Mark_Up_Your_Screenshots_In_Android_12⠀⇛ # ⚓ TCL_X20_SE_and_TCL_20A_5G_with_Triple_Rear_Camera, Android_11_Launched_in_the_United_States;_Read_More_| PINKVILLA⠀⇛ # ⚓ Best_photo_widgets_for_Android_–_Phandroid⠀⇛ # ⚓ Best_Android_app_deals_of_the_day:_House_of_Da_Vinci 2,_more_–_9to5Toys⠀⇛ # ⚓ Lenovo_L5:_1080p_projector_launches_with_Android_TV for_US$199.99_–_NotebookCheck.net_News⠀⇛ # ⚓ Video_And_Photo_Processing_On_Android:_What_Do_You Need_To_Know_First?⠀⇛ # ⚓ 3_easy_ways_to_share_images_and_files_from_Android_to PC_and_vice_versa⠀⇛ o § Free, Libre, and Open Source Software⠀➾ # ⚓ The_Apache_News_Round-up:_week_ending_29_October_2021⠀⇛ Farewell, October –we’re wrapping up the month with another great week. # ⚓ Apache_Month_in_Review:_October_2021_:_The_Apache_Software Foundation_Blog⠀⇛ Welcome to the latest monthly overview of events from the Apache community. # ⚓ Blender_Community_Releases_Sprite_Fright_Animated_Movie_– LinuxStoney⠀⇛ The Blender Project has unveiled a new animated short, ” Sprite Fright “, a Halloween-themed 80s horror comedy movie. The project was led by Matthew Luhn , known for his work at Pixar Studios. The film was created using only open working tools for modeling, animation, rendering, compositing, motion tracking and video editing. The project acted as a test base for honing new capabilities and technologies for creating modern visual effects developed in the new Blеnder branches. This is the thirteenth animation project of the Blender community. # ⚓ Tor_Forum:_a_new_discussion_platform_for_the_Tor Community⠀⇛ Communicating and finding help online is crucial to building a solid community. After many years of using emails, mailing lists, blog comments, and IRC to help Tor users, we believe that time has come to improve our discussion channels. Today, we’re happy to announce a new discussion and user support platform: the Tor Forum. # § Web Browsers⠀➾ # § Chromium⠀➾ # ⚓ Version_95_of_Chromium_and_its_un-googled sibling_available_for_download⠀⇛ I have uploaded packages for Chromium 95.0.4638.69 as well as its un-googled variant. The source release was just before the weekend and the compilation was un- eventful, which is nice for a change. Get the chromium or chromium-ungoogled packages from slackware.nl and enjoy the update. # § Mozilla⠀➾ # ⚓ 94.0_Firefox_Release⠀⇛ With 94, you’ll find a selection of six fun seasonal Colorways (available for a limited time only). Now you can find a color to suit (or lift) your every mood. Fun fact: Did you know we have more daily users with color themes than dark or Alpenglow on Beta? With Firefox 89, 32% of users clicked through to customize their color theme. And that was just on the first day! We decided to introduce these new Colorways to give our users more to love. # ⚓ Firefox_94.0_Released_With_Linux_Build_Using EGL_For_Better_Performance,_Power_Savings⠀⇛ Firefox 94.0 is now available and for a change it’s quite exciting on the Linux front. Firefox 94.0 introduces seasonal color schemes, support for using about: unloads to release system resources by manually unloading tabs without closing them, Site Isolation is now enabled for helping fend off side-channel attacks like Spectre, and a wide variety of bug fixes. The bug fixes in Firefox 94.0 also include some performance and security fixes. # ⚓ Introducing_New_Colorways_for_Firefox_94⠀⇛ Today, Firefox is launching Colorways, a new feature that allows our users to express their most authentic selves and to bring them joy while browsing the web. As we challenge what the browser has been, and expand and define the vision of what Firefox browser is and can be, part of that challenge is to ask ourselves “who is it for and who can use it easily and feel included in the experience?” We caught up with Mikal Lewis, Senior Director, Product Management for Firefox, to hear more about his vision for Firefox and the impetus for launching Colorways. # ⚓ Firefox_brings_you_a_new_homepage_making_it easier_to_jump_back_in_to_the_stuff_you_care about_on_your_mobile_devices⠀⇛ Today, we are rolling out a brand new Firefox homepage on Android and iOS, designed for those on-the-go, short bursts of online interactions that are constantly interrupted by life. With this new Firefox homepage we wanted to lift that heavy mental burden of remembering to finish those halfway read articles or vacation research until you are ready to jump back and finish those tasks. We’ve simplified and organized your on-the-go mobile experiences into one central location, complete with new features to help you ignore the online noise and focus on what matters to you. Welcome to your new Firefox homepage, delivering a fast, intuitive and useful browser! In May 2021, we redesigned the browsing experience with a new Firefox release. In today’s mobile release we continue to put our users first and today introduce a completely new homepage experience that helps you accomplish what you set out to do whenever you go online. The new Firefox home is a re- entry point for you to access previously opened tabs with articles you have yet to finish, sites you’ve bookmarked, and search histories organized by topics so you can find it all in one central spot. Today’s mobile release is just the beginning as we plan to roll out more features that build on this experience. Check out the new homepage, a place to organize your thoughts and interests… # ⚓ Firefox_for_iOS_and_Android_gets_new_homepage with_previously_viewed_tabs,_searches,_more⠀⇛ Mozilla launched a major Firefox update for Mac, iOS, Android, and more this past summer and now the popular browser gets another useful overhaul today. For iOS and Android, Firefox now has a new homepage with a focus on recently viewed tabs and searches, one-tap private mode, and more. # ⚓ Mozilla_suggests_improvements_to_Canada’s online_harms_agenda⠀⇛ Later this year the Canadian government will publish new laws to overhaul how platforms in the country must tackle illegal and harmful content. The government’s desire to intervene is unsurprising – around the world, policymakers and the public are pressing for greater responsibility and accountability on the part of Big Tech. Yet in its proposal that platforms take down more content in ever-shorter periods of time, the government’s approach merely responds to symptoms and not structural causes of online harms. Worse still, the government’s proposal includes some suggested policy ideas that would have the opposite effect of making online spaces healthier and more inclusive. As we seek to advance a better vision for platform accountability across the world, we’re weighing-in here with some recommendations on how Canadian lawmakers can use this moment to meaningfully enhance responsibility while protecting rights and competition online. As detailed in a white paper released in the summer, the government wants content-sharing platforms to monitor their services for certain forms of objectionable content and act on user reports within 24 hours. The new rules will apply to some categories of content that are already illegal under the criminal code (like child abuse material) as well as forms of content that, though not captured under the criminal code, are nonetheless considered harmful when tranmitted though online services (e.g. unconsensual nude imagery). A new regulator will police the rules, and companies will be subject to strict retention and reporting requirements. # § SaaS/Back End/Databases⠀➾ # ⚓ PostgreSQL:_PostgreSQL_JDBC_42.3.1_released⠀⇛ The PGJDBC team are proud to announce release 42.3.1 of the JDBC driver for PostgreSQL This is mainly a regression fix to fix an issues with binary transfers of numeric. # ⚓ PostgreSQL:_ODB_2.5.0-b.21_adds_support_for_bulk operations_in_PostgreSQL_14⠀⇛ The just published ODB C++ ORM version 2.5.0- b.21 adds support for bulk operations in PostgreSQL using the new pipeline mode introduced in libpq 14. For background on bulk operations (which until now were only available in ODB when using Oracle and SQL Server) see Section 15.3, “Bulk Database Operations” in the ODB manual. Note that while this functionality requires libpq version 14 or later, it s # ⚓ PostgreSQL:_PostgreSQL_Weekly_News_–_October_31, 2021⠀⇛ pg_statement_rollback v1.3, an extension that adds server side transaction with rollback at statement level, released. # ⚓ PostgreSQL:_Babelfish_for_PostgreSQL⠀⇛ Babelfish for PostgreSQL is a dual licensed, Apache-2.0 and PostgreSQL, open source project that adds additional syntax, functions, data types, and more to PostgreSQL to help in the migration from SQL Server. It includes a network end-point added to PostgreSQL to enable your PostgreSQL database to understand the SQL Server wire protocol and commonly used SQL Server commands. With Babelfish, applications that were originally built for SQL Server can work directly with PostgreSQL, with little to no code changes, and without changing database drivers. # ⚓ PostgreSQL:_PostgresDAC_3.11_meets_PostgreSQL_14_and RAD_Studio_11_Alexandria!⠀⇛ PostgresDAC is a direct access component suite for RAD Studio (Delphi and C++Builder)/ FreePascal/Lazarus and PostgreSQL, EnterpriseDB, Amazon RDS, PostgresPro, and Heroku Postgres. # ⚓ PostgreSQL:_EDB_to_Host_Free_Virtual_Conference_for PostgreSQL_Users_in_Europe⠀⇛ After the huge success of our Postgres Build 2020 (PG Build) online conference, the event returns in 2021 with an expanded agenda, more speakers, more tracks, and the latest in- depth talks around PostgreSQL. PG Build 2021 will bring together the world’s leading PostgreSQL experts, enterprises, community members, and thought leaders to connect and explore the latest in PostgreSQL technology and use cases. # § CMS⠀➾ # ⚓ WordPress_brings_“Sponsored_Crap”_to_inject_into_my posts. [Ed: Reminder that WordPress dot org is free and WordPress dot com is not free, you might in fact just be the product when you're not paying for it]⠀⇛ This is just a heads up that I have nothing to do with anything you see that says “Sponsored Content” on my blog and I am considering moving to a different platform. WordPress just announced that they will be doing this to anyone who doesn’t pay them and there’s no way to opt out of it other than that. # § FSF⠀➾ # § Licensing/Legal⠀➾ # ⚓ Because_Of_Course:_Trump’s_SPAC_Deal_May_Have Broken_The_Law⠀⇛ If you thought that Trump’s new Truth Social website’s potential legal problems with its apparent failure to abide by the license on the open source code it seems to be using would be the worst legal problems facing the site, well, you underestimated The Donald. There’s been plenty of talk about the SPAC deal that valued the company at billions of dollars through one of those reverse merger IPOs. But, now the NY Times is reporting that the way the deal was done may have violated securities laws. So on brand. # § Programming/Development⠀➾ # ⚓ The_Qt_6_QML_Book⠀⇛ One question that I often think about is: how to do you learn best? I come from a time where you read your BASIC reference manual until it fell apart. Perhaps you picked up another little nugget of knowledge in each iteration. But things have progressed. There are videos, books, online teaching materials, code challenges, and much much more. What brought me to Qt back in the late ’90s was the quality of the reference documentation (and that it ran on a 64-bit architecture). # § Perl/Raku⠀➾ # ⚓ berrybrew_version_1.36_released!⠀⇛ I’ve released version 1.36 of berrybrew, the Perlbrew for Windows. I’ve also reached out to see how I can become part of the Strawberry Perl team to get back on track with the release of new Strawberry Perls. If you have any information on the release procedure for Strawberry, or know anyone on that team I might be able to contact to get things moving forward again, please let me know. # § Java⠀➾ # ⚓ How_to_choose_the_best_Java_garbage_collector_| Red_Hat_Developer⠀⇛ Garbage collection (GC) performs dynamic memory management in many modern programming languages. For developers, sophisticated garbage collection lightens the load of worrying about memory management. This article is the third in a four-part series that explains how to improve Java performance by choosing and tuning a garbage collector. Part 1 explained the basics of garbage collection and how to monitor the stages and levels of garbage collection. Part 2 delved into memory usage by the Java Virtual Machine (JVM) and the compiler options that control it. This article compares Java garbage collectors and explains how to use your application’s throughput, latency, and footprint requirements to choose the right one for your needs. * § Leftovers⠀➾ o ⚓ Day_of_the_Dead⠀⇛ o ⚓ Why_You_Should_Root_for_Dusty_Baker_in_This_Year’s_World_Series⠀⇛ You don’t have to care about baseball to care about Houston Astros manager Dusty Baker, whose team is heading to the sixth game in the World Series tomorrow. He is a civil rights hero: a Black Major League Baseball manager who’s taken five teams, in three decades, in both leagues, to the playoffs and/or World Series. o ⚓ Forget_‘The_Kids_These_Days’;_It’s_The_Adults_And_Their_Moral Panics_To_Worry_About⠀⇛ A recent episode of the Reply All podcast, Absolutely Devious Lick, touched on a bunch of interesting points regarding the never-ending debates about social media, content moderation, and how it’s supposedly damaging the kids these days. It’s worth listening to the entire episode, but it begins by talking about a very slightly viral TikTok “challenge” which became known as Devious Licks — lick being slang for something you stole. It started with a kid putting up a TikTok video of him holding a box of disposable masks, suggesting that he had stolen it from the school. Because school kids sometimes do stupid things to copy their stupid friends, a few others posted similar videos, including one early one of a kid taking a soap dispenser. And then there were some stories of it spreading and people going more extreme, because, you know, kids. But it didn’t seem to spread that far initially. o ⚓ Could_age_verified_phones_for_kids_work?_SHOULD_they?_|_Stop_at Zona-M⠀⇛ I do not say this because COPPA is a US-only law. Nor I say it because, in practice the only way to be sure that, for example, parents didn’t give their children unrestricted phones would be to continuously take those phones from the children, and check (that is, basically, to never leave the children without some guardian). I say this because there is no need at all of anything so complicated and expensive. I say this because, if children means “humans less than 13, maybe 14 years old”, we already have all the technology that would really help them to not waste countless hours of sleep, or to avoid all sorts of abuse on social media. It’s technology that is already available everywhere, and it’s really affordable too. o § Science⠀➾ # ⚓ Magnesium:_Where_It_Comes_From_And_Why_We’re_Running_Out_| Hackaday⠀⇛ Okay, we’re not running out. We actually have tons of the stuff. But there is a global supply chain crisis. Most of the world’s magnesium is processed in China and several months ago, they just… stopped. In an effort to hit energy consumption quotas, the government of the city of Yulin (where most of the country’s magnesium production takes place) ordered 70% of the smelters to shut down entirely, and the remainder to slash their output by 50%. So, while magnesium remains one of the most abundant elements on the planet, we’re readily running out of processed metal that we can use in manufacturing. [...] We’ve established just how much we need magnesium, so what happens when we can’t get it? If the factories in China stay shut down for much longer, that’s a reality we may be facing. Auto makers will do what they can to get their hands on suitable aluminum, but there may not be enough to go around and some experts believe that this could cause car assembly lines to grind to a halt until the upstream supply chain is back in order. It isn’t only cars that would be in short supply. Consumer electronics production could suffer as well (as if the global chip shortage wasn’t already enough). The ramifications will be far-reaching and you’re likely to feel them even if you aren’t planning on buying a new car or laptop next year. Magnesium and aluminum prices have been increasing, and even smaller fabrication shops have started stocking up on materials that they worry won’t be available in a few months. It may be a good time to think about alternatives for that machined aluminum enclosure you were going to design for your latest project. o § Hardware⠀➾ # ⚓ Modded_GBA_SP_Does_Its_Best_Switch_Impression_|_Hackaday⠀⇛ The whole idea behind the Nintendo Switch is that the system isn’t just a handheld, but can be converted into a more traditional home game console when placed into its dock. The wireless controllers even pop off the sides so you can kick back on the couch and enjoy your big-screen gaming from a distance. Judging by how many units Nintendo has sold of their latest system, it’s clearly a winning combination. # ⚓ Janksy_Robot_Paints_Murals_One_Dot_At_A_Time_|_Hackaday⠀⇛ [Stuff Made Here] has a new shop, with a huge blank wall. A blank white wall just wouldn’t do, so rather than paint the wall himself, he designed a robot to do it for him. (Video, embedded below.) The result is Janksy. A huge machine made of metal, wood, and 3D printed parts. Janksy is an ingenious design in that it has two sets of X and Y axis. A large, slow-moving system of rails and cables positions the robot roughly in the right area of the wall. From there a much smaller, but faster and more precise motion system makes the final moves. o § Health/Nutrition⠀➾ # ⚓ ‘We’re_Not_Giving_Up’:_Sanders,_Other_Progressives_Fight_to Rescue_Drug_Price_Reforms⠀⇛ Sen. Bernie Sanders, lawmakers in vulnerable districts, and grassroots progressive groups are ramping up their last-ditch effort to rescue a plan to lower U.S. prescription drug prices as the longstanding—and widely popular—Democratic campaign promise is at risk of being excluded from President Joe Biden’s signature domestic policy bill. “It is outrageous that we continue to pay the highest prices in the world for prescription drugs.” # ⚓ Land_of_Capital⠀⇛ The great surprise of 2016 was not the rise and election of Donald Trump; that path had been laid out for more than 50 years by Barry Goldwater, George Wallace, Ronald Reagan, Pat Buchanan, Newt Gingrich, and the two Bushes. The great surprise was the emergence of Bernie Sanders. A proud, self- proclaimed democratic socialist, Sanders set his political sights on capitalism—especially in its corporate form—which he clearly named and then blamed for the economic inequalities, social injustices, concentrations of power, and neglect of public health that so deeply afflicted the country. Although he identifies as an independent in the Senate, Sanders chose to seek the Democratic # ⚓ Sanders_Says_He’s_Still_Working_to_Get_Drug_Price_Plan_Into Reconciliation_Bill⠀⇛ # ⚓ G20_Summit_Deemed_‘Abysmal_and_Total_Failure’_on_Vaccine Equity,_Climate_Action⠀⇛ Leaders of the world’s richest nations wrapped up the Group of 20 Summit in Rome on Sunday after taking virtually no concrete action to tackle the coronavirus pandemic and the intensifying climate crisis, drawing condemnation from human rights advocates who deemed the gathering’s outcome an “abysmal and total failure.” “G20 leaders could have taken urgent action to dramatically scale up manufacturing and access to Covid-19 vaccines around the world, promote a fair economic recovery, lower dangerous greenhouse gas emissions, and help the poorest countries adapt to the climate change already happening,” Jörn Kalinski, senior adviser at Oxfam International, said in a statement. “The bottom line is that this summit failed to deliver much of anything for people, planet, or prosperity.” # ⚓ Babies_Are_Dying_of_Syphilis._It’s_100%_Preventable.⠀⇛ When Mai Yang is looking for a patient, she travels light. She dresses deliberately — not too formal, so she won’t be mistaken for a police officer; not too casual, so people will look past her tiny 4- foot-10 stature and youthful face and trust her with sensitive health information. Always, she wears closed-toed shoes, “just in case I need to run.” Yang carries a stack of cards issued by the Centers for Disease Control and Prevention that show what happens when the Treponema pallidum bacteria invades a patient’s body. There’s a photo of an angry red sore on a penis. There’s one of a tongue, marred by mucus-lined lesions. And there’s one of a newborn baby, its belly, torso and thighs dotted in a rash, its mouth open, as if caught midcry. # ⚓ Nursing_Home_Residents_Are_Overlooked_in_Scramble_for_COVID Antibody_Treatments⠀⇛ # ⚓ Florida_strips_federal_funding_from_schools_as_further punishment_for_masking_|_Ars_Technica⠀⇛ The state of Florida this week withheld nearly $700,000 in funding from two school districts as part of an escalating feud led by Florida Gov. Ron DeSantis over school mask requirements. The state had previously financially penalized the Alachua and Broward school boards by docking their salaries for issuing school mask requirements, which DeSantis has worked to ban. In response to the financial penalties, the Biden administration last month awarded the counties federal funding to compensate for losses. Alachua County was awarded $147,719 and Broward County Public Schools received $420,957 in federal grants under the US Department of Education (USDOE) Project Safe grant. o § Integrity/Availability⠀➾ # § Proprietary⠀➾ # § Security⠀➾ # ⚓ Securing_the_Open-Source_supply_chain_with Ubuntu_Pro_on_Google_Cloud⠀⇛ It’s official: since the outbreak of the COVID-19 pandemic, cybercrime has increased by 600%. Among these, ransomware attacks are estimated to cost $6 trillion in 2021 alone. And there were nearly 550,000 ransomware attacks per day in 2020. The question is: are your workloads secure enough? In this blog, we will discuss how to make your Open Source workloads more secure in one second. # ⚓ Google_to_Pay_Hackers_$31,337_for_Exploiting Patched_Linux_Kernel_Flaws⠀⇛ Google on Monday announced that it will pay security researchers to find exploits using vulnerabilities, previously remediated or otherwise, over the next three months as part of a new bug bounty program to improve the security of the Linux kernel. # ⚓ Google_just_tripled_its_bounty_for_Linux_kernel bugs._Here’s_why⠀⇛ # ⚓ GCC_&_LLVM_Patches_Pending_To_Fend_Off_Trojan Source_Attacks_–_Phoronix⠀⇛ Making rounds today are the “Trojan Source” attacks by which text displayed to the end-user/developer doesn’t match what is actually being executed. The problem stems from Unicode standards and could lead to malicious code being inadvertently introduced into upstream code-bases that could be overlooked during code review processes, etc. GCC and LLVM/Clang are among the early compilers preparing defenses against Trojan Source style attacks. # ⚓ Trojan_Source_attack_for_introducing_code changes_invisible_to_the_developer_– itsfoss.net⠀⇛ Researchers at the University of Cambridge have published a new technique for subtly substituting malicious code in peer-reviewed sources. The prepared attack method ( CVE-2021-42574 ) is presented under the name Trojan Source and is based on the formation of text that looks different to the compiler / interpreter and the person viewing the code. Examples of application of the method are demonstrated for various compilers and interpreters supplied for C, C ++ (gcc and clang), C #, JavaScript (Node.js), Java (OpenJDK 16), Rust, Go and Python. The method is based on the application of special Unicode characters in the comments to the code, which change the display order of bidirectional text. With the help of such control characters, some parts of the text can be displayed from left to right, and others from right to left. In everyday practice, such control characters can be used, for example, to insert Hebrew or Arabic strings into a file with code. But if you combine lines with different text directions in one line, using the specified characters, passages of text displayed from right to left can overlap the already existing ordinary text displayed from left to right. # § Privacy/Surveillance⠀➾ # ⚓ Facebook_relaunches_itself_as_‘Meta’_in_a clear_bid_to_dominate_the_metaverse⠀⇛ But is this just a shallow PR exercise, with Zuckerberg trying to reset the Facebook brand after several scandal-ridden years, or is it a genuine bid to set the company on course for what he sees as the future of computing? # ⚓ Mark_Zuckerberg’s_metaverse_may_be_as privacy_flawed_as_Facebook_|_Fortune⠀⇛ The planned metaverse, from Meta, the parent company of Facebook, raises significant questions about the future of data privacy. # ⚓ California_Prosecutors_Are_Still_Trying To_Get_Signal_To_Hand_Over_User_Info_It Simply_Doesn’t_Possess⠀⇛ Encrypted messaging app Signal is slowly educating federal prosecutors on the meaning of the idiom “blood from a stone.” Usually this refers to someone who is judgment-proof (or extortion-proof or whatever), since you can’t take money a person doesn’t have. # ⚓ What_Mark_Zuckerberg_Really_Means_When_He Talks_About_the_Metaverse⠀⇛ The company is doubling down on user surveillance. # ⚓ All_reject_our_pointless_fridge overlords⠀⇛ The only really smart fridge is the one that is as small as possible, as energy-efficient as possible, as repairable as possible, and not connected to the Internet. It is a sad and dumb reality that we do not have much real choices in this matter. Dan himself points out that he has that fridge because it’s what his landlord unilaterally decided to buy. But it’s never too late to ask for REALLY smart fridges, the next time you need one. And if you already have one of these disgraces, do yourself and your stress levels a favour: unplug it from the net NOW. o § Defence/Aggression⠀➾ # ⚓ Legal_Brief_Details_What_Trump’s_Trying_to_Hide_From_the January_6_Committee⠀⇛ # ⚓ Why_the_Troubled_U.S._Empire_Could_Quickly_Fall_Apart⠀⇛ The United States has 4.25 percent of the world’s population yet accounts for about 20 percent of global deaths from COVID-19. A rich global superpower with a highly developed medical industry proved to be badly unprepared for and unable to cope with a viral pandemic. It now wrestles with a huge segment of its population that seems so alienated from major economic and political institutions that it risks self-destruction and demands the “right” to infect others. Refusing to accept lifesaving COVID-19 vaccine and mask mandates in the name of “freedom” mixes a frightening stew of ideological confusion, social division, and bitterly rising hostility within the population. The January 6 events in Washington, D.C., showed merely the tip of that iceberg. Levels of debt—government, corporate, and household—are all at or near historical records and rising. Feeding and thereby supporting the rising debts is the Federal Reserve with its years of quantitative easing. Officials at the highest levels are now discussing the possible issuance of a trillion-dollar platinum coin to have the Fed give that sum in new credit to the U.S. Treasury to enable more U.S. government spending. The purpose goes far beyond political squabbling over the cap on the national debt. The goal is nothing less than freeing the government to inject still more massive amounts of new money into the capitalist system to sustain it in times of unprecedented difficulty. The Fed learned that today’s capitalism needs such quanta of monetary stimulus thanks to the three recent crashes (2000, 2008, and 2020) witnessed by the capitalist system. A desperate empire approaches a version of the Modern Monetary Theory that empire leaders mocked and rejected not very long ago. # ⚓ “On_Liberty”_–_Judge_Learned_Hand’s_Wisdom_from_1944_More True_Today⠀⇛ What impressed me most about Judge Hand was a brief address he delivered in 1944, in the midst of World War II, to an audience gathered in New York’s Central Park on the occasion of “I Am an American Day.” There was every temptation to give a “red, white and blue” speech of exuberant patriotic rhetoric. After all, the battles on the European and Pacific fronts were furious and producing mass casualties on all sides. Judge Hand resisted narrating the customary, nationalistic exaltations. Instead, he provided gentle transcendental wisdom for the ages. He spoke of people as being either the progenitors or destroyers of ‘liberty,’ as he broadly and deeply defined that abused word. We give birth or foster the light or darkness of a society. We are responsible, by clear inference, for allowing the concentrations of tyrannical exercises of power by the avaricious, despotic few over the many. # ⚓ Opinion_|_Now_Is_the_Time_to_Be_Angry:_Remembering Forgotten_Afghanistan⠀⇛ I know, I know. It’s the last thing you want to hear about. Twenty years of American carnage in Afghanistan was plenty for you, I’m sure, and there are so many other things to worry about in an America at the edge of… well, who knows what? But for me, it’s different. I went to Afghanistan in 2002, already angry about this country’s misbegotten war on that poor land, to offer what help I could to Afghan women. And little as I may have been able to do in those years, Afghanistan left a deep and lasting impression on me.  # ⚓ Gitmo_Jurors_Liken_CIA_Torture_to_Acts_by_‘Most_Abusive Regimes_in_Modern_History’⠀⇛ Seven out of the eight members of a military jury called for clemency to be granted in the case of a Guantanamo detainee in light of his detention without due process and said his abuse at the hands of the CIA was “closer to torture performed by the most abusive regimes in modern history” rather than the euphemistic “enhanced interrogation techniques” claimed by the agency. “The treatment of Mr. Khan in the hands of U.S. personnel should be a source of shame for the U.S. government.” # ⚓ The_United_States_is_Organizing_a_Color_Revolution_in_Cuba for_November_15⠀⇛ The United States government is playing a key role in organizing, promoting and amplifying upcoming nationwide protests in Cuba planned for November 15. # ⚓ “Stain_on_the_Moral_Fiber_of_America”:_Military_Jurors Decry_Majid_Khan’s_Torture_at_CIA_Black_Sites⠀⇛ In a major development, a Guantánamo Bay detainee described his torture at CIA black sites for the first time in court last week, prompting military jurors to call his treatment a “stain on the moral fiber of America.” On Thursday, Majid Khan became the first Guantánamo prisoner to describe publicly the torture he experienced after being detained in Pakistan and then being held at CIA black sites, including forced feedings, waterboarding and other physical and sexual abuse. Khan was sentenced Friday to 26 years but under a previous deal is scheduled for release in February 2022. His unprecedented testimony only represents the “top part of the iceberg,” says Baher Azmy, legal director of the Center of Constitutional Rights, which has helped represent Majid Khan. “We need more meaningful accountability for what the United States government did to Majid and many dozens of other detainees in the so-called global war on terror.” o § Environment⠀➾ # ⚓ Over_700_Groups_Demand_‘Real_Climate_Solutions,_Not_Net- Zero_Promises’⠀⇛ As world leaders gathered in Glasgow, Scotland on Monday for a United Nations climate summit, more than 700 organizations from nearly 100 countries took aim at net-zero pledges “premised on the notion of canceling out emissions in the atmosphere rather than eliminating their causes.” “We are concerned that rich countries and polluting corporations will push ahead with ‘false solutions’ at COP26.” # ⚓ ‘Words_Won’t_Save_Us’:_Climate_Movement_Slams_‘Empty- Handed’_Biden_at_COP26⠀⇛ President Joe Biden’s speech at the opening ceremony of the COP26 conference on Monday was met with an icy response from the U.S. climate movement, which warned his lofty rhetoric will be meaningless if he continues to resist sweeping action to slash emissions, end all new fossil fuel projects, and swiftly transition to renewable energy. “All the negotiation in the world is ultimately hollow unless Biden acts boldly to end the fossil fuel era at home.” # ⚓ Opinion_|_Why_We_Must_Defund_the_Global_Climate_Wall⠀⇛ At a National Security Council meeting in September, U.S. Secretary of State Anthony Blinken said that the consequences of climate change “are falling disproportionately on vulnerable and low- income populations.” He continued, “And they’re worsening conditions and human suffering in places already afflicted by conflict, high levels of violence, instability.” He assured his colleagues that the climate crisis is a “core element of U.S. foreign policy” and that “every bilateral and multilateral engagement we have—every policy decision we make—will impact our goal of putting the world on a safer, more sustainable path.” # ⚓ Letter_Accusing_World_Leaders_of_Climate_‘Betrayal’_Signed by_1_Million_People—And_Growing⠀⇛ As activists gathered Monday outside the United Nations Climate Change Conference in Glasgow, Scotland to protest world leaders’ collective failure to address the worsening planetary emergency, a petition led by four young women at the center of the fight for climate action quickly gathered over a million signatures. “This is not a drill. It’s code red for the Earth.” # ⚓ As_COP26_Climate_Talks_Begin,_Biden_Pressures_OPEC_to_Boost Oil_Production⠀⇛ Before U.S. President Joe Biden could tout Washington’s ostensible commitment to addressing the planetary emergency at the COP26 climate conference that kicked off Sunday in Glasgow, the White House doubled down on its ongoing effort to pressure the world’s oil-producing giants to boost supply, provoking frustration and alarm in the process. “Do you see any irony in pushing [OPEC+] to increase oil production at the same time that you’re going to COP26 to urge people to lower emissions?” Jeff Mason of Reuters asked Biden on Sunday at the conclusion of the latest G20 meeting in Rome. # ⚓ Climate_change:_US_vs._China_—_Here’s_how_the_two_biggest emitters_stack_up_–_CNN⠀⇛ China and the United States are the world’s two biggest greenhouse gas emitters, so any attempt to address the climate crisis will need to involve deep emissions cuts from these two powerhouse nations. China’s emissions are more than double those of the US, but historically, the US has emitted more than any other country in the world. There are many factors to consider when judging a country’s climate credentials, and as leaders gather in Glasgow, Scotland for COP26 from Sunday, the US’ and China’s plans will be in the spotlight. Here’s how the two stack up against each other. # ⚓ Protests_at_COP26_Call_on_UK_to_Block_Massive_Cambo_Oil Field_Off_Scottish_Coast⠀⇛ # ⚓ This_Is_the_Decade_to_Reduce_Emissions⠀⇛ This column is part of Covering Climate Now, a global journalism collaboration cofounded by Columbia Journalism Review and The Nation to strengthen coverage of the climate story. # ⚓ Climate_Justice_in_America⠀⇛ By contrast, climate justice is about the interaction between human beings and nature. It is about issues like global warming understood as an ethical and political issue. Necessarily, climate justice involves social equality, human rights, collective rights, animal rights and our common responsibilities to prevent global warming. Despite the recent flooding of sections of New York, it is clear by now that there are disproportional impacts of climate disruptions on the world’s most vulnerable people. The promise of capitalism as the solution to global warming might turn out to be a hallucination. Instead, many climate justice advocates have been in the forefront of critiquing policy measures that aim to implement emission reductions through so-called market mechanisms. # ⚓ Rich_Countries_Bring_“Tough_Talk_on_Climate”_to_COP26_But No_New_Plans_or_Money_to_Curb_Global_Emissions⠀⇛ As U.S. President Joe Biden and other world leaders gather amid massive protests in Glasgow for COP26, the U.N. Climate Change Conference, we look at the growing pressure on countries to limit global temperature rise to 1.5 degrees Celsius and avert the most damaging effects of the climate crisis. Leaders of the G20, representing the 20 wealthiest nations, gathered ahead of COP26 and pledged to do more to curb emissions but offered few specifics on reaching that goal, despite representing the countries responsible for about 80% of greenhouse gases released into the atmosphere. “What we’re seeing here is lots of tough talk on climate, but lack of plans, lack of policies and refusal to put money on the table,” says Asad Rehman, executive director of War on Want and lead spokesperson for the COP26 Coalition. Rehman also gives an overview of the demands from protesters, and plans for the next two weeks. # ⚓ ‘The_Earth_Is_Speaking’:_Indigenous_Activists_Tell_COP26 There’s_No_Climate_Solution_Without_Them⠀⇛ As the United Nations Climate Change Conference—also known as COP26—got underway in Glasgow, Scotland this week, Indigenous activists from around the world warned that failure to center their peoples’ voices and solutions would seriously hamper efforts to tackle the growing planetary emergency. “We can develop actions based on our culture and our traditional knowledge.” # ⚓ Protests_at_COP26_Climate_Summit_Call_on_U.K._to_Block Massive_Cambo_Oil_Field_Off_Scotland’s_Coast⠀⇛ As the U.K. government tries to claim the mantle of climate leadership at the U.N. Climate Change Conference, we speak with Mary Church, head of campaigns at Friends of the Earth Scotland. She describes how activists are calling on U.K. Prime Minister Boris Johnson to block the development of the giant Cambo oil field off the coast of Scotland, which would run counter to the U.N. goals of phasing out fossil fuels. “We know that fossil fuels need to be phased out long, long before 2050, but this proposal is to keep on drilling oil until 2050,” says Church, adding that the extraction of 800 million barrels of oil would be “the equivalent of 10 years of Scotland’s annual emissions.” # ⚓ ‘Shame_on_You!’:_Climate_Activists_Confront_World_Leaders at_Lavish_COP26_Dinner⠀⇛ Chanting “shame on you,” activists rallied amid a heavy police presence Monday evening outside a swanky reception for world leaders and others attending the United Nations Climate Change Conference in Glasgow, Scotland to protest their inadequate response to the planetary emergency. Members of Britain’s royal family and corporate executives joined heads of state and other leaders at the exclusive dinner event, which was hosted by British Prime Minister Boris Johnson at the Kelvingrove Art Gallery and Museum. # ⚓ Many_Voices_from_Global_South_Shut_Out_of_U.N._Climate Summit_as_Vaccine_Apartheid_Limits_Travel_to_U.K.⠀⇛ This year’s U.N. Climate Change Conference in Glasgow may be the whitest and most privileged one ever, with thousands from the Global South unable to attend because of lack of access to COVID-19 vaccines and travel restrictions. The global inequity in vaccine access mirrors the disproportionate impact of the climate crisis that has fallen mostly on poor countries least responsible for emissions, says climate activist Dipti Bhatnagar in Mozambique. “The people who need to be there, who need to hold people accountable, are not going to be there,” says Bhatnagar, climate justice and energy coordinator at Friends of the Earth International, who was unable to attend the climate conference in Scotland because of a lack of access to COVID-19 vaccines. “What is going to come out of this COP is going to be largely illegitimate because of the way that they’ve organized it and because of the intentions behind it.” # ⚓ Opinion_|_Street_Murals_to_Glasgow:_“Defund_Climate Chaos!”⠀⇛ On the eve of the Glasgow Climate Talks, wildfire survivors, Indigenous communities and Northern California community groups came together to paint the streets, send a message to Glasgow, and lay a creative siege to the biggest investor in climate chaos—BlackRock. It was part of a day of global action to #DefundClimateChaos with actions in over 100 cities in 26 countries on every continent—and painting street murals was a popular medium for the message. # ⚓ Lawyers_for_Landmark_Kids_Climate_Suit_Cut_Off_Talks_With Biden_DOJ⠀⇛ Lawyers representing a group of young people in a landmark climate lawsuit said Monday that settlement discussions with the U.S. Department of Justice ended without resolution and that they’re now eagerly awaiting a trial date to argue that the nation’s fossil fuel-based energy system violates the youths’ constitutional rights. “Emergency falls short in describing the climate situation and its devastating impact on these young Americans.” # § Energy⠀➾ # ⚓ The_Problem_With_Calling_Fracked_Gas_‘Responsibly Sourced’⠀⇛ By Ted Auch, PhD, FracTracker Alliance, with contributions from Shannon Smith of FracTracker Alliance The fracked natural gas industry has never been the most responsible or efficient consumer of resources. Drillers are using ever-increasing amounts of water and sand in order to produce the same volume of gas, with a corresponding rise in the levels of solid and liquid waste created. # § Wildlife/Nature⠀➾ # ⚓ A_Win_for_Lynx_and_Grizzly_Bears_in_Montana⠀⇛ In 2013, because lynx were being killed in traps set for other animals in violation of the Endangered Species Act, the Alliance for the Wild Rockies, Friends of the Wild Swan, and WildEarth Guardians, represented by the Western Environmental Law Center, filed a lawsuit in federal district court. In 2015, we signed a formal settlement agreement with the Montana Department of Fish, Wildlife and Parks to restrict the types of trapping allowed in lynx habitat. The settlement agreement established a new Lynx Protection Zone covering occupied lynx habitat in Northwest Montana and the Greater Yellowstone area where special trapping regulations were designed to protect lynx, and indirectly, grizzlies. The agreement also put into place a three-year moratorium on wolverine trapping. o § Finance⠀➾ # ⚓ Opinion_|_Behold_and_Beware!_The_Age_of_Trillionaires_Is Coming⠀⇛ Barely a year ago, my colleagues Chuck Collins and Omar Ocampo noted the passing of “a disturbing milestone in the U.S. history of concentrated wealth and power.” On August 13, 2020, just twelve obscenely wealthy Americans held a combined $1.015 trillion. They called those twelve the “Oligarchic Dozen.” # ⚓ America_as_Tax_Haven:_It’s_Becoming_Part_of_US_Foreign Policy⠀⇛ And there’s more: The US government can provide you with vital political support when you run into trouble at home. Case in point: Ecuador, where President Guillermo Lasso faces a major scandal as a result of the Pandora Papers’ revelations of his offshore assets. On October 19, US Secretary of State Antony Blinken paid a special visit to Ecuador, a move that has been presented by the Ecuadorian government as a show of support for the beleaguered president. On October 10, the Ecuadorian National Assembly opened a formal investigation into the president’s finances. The legislative commission investigating Lasso seeks to establish whether he violated a law barring public officials, including presidents, from having assets in tax havens. # ⚓ 250_Millionaires_to_Congress:_‘Now_Is_the_Time’_to_Tax Billionaires⠀⇛ As congressional Democrats continue to revise a pared-back version of the Build Back Better Act, a group of roughly 250 millionaires on Monday urged party leaders to include an “overwhelmingly popular” proposal to tax billionaires’ annual investment gains in the final package, after it was excluded from the framework President Joe Biden unveiled last week. “Unless Congress acts now, billionaires will continue to be allowed by Congress to pay far less than their fair share of taxes.” # ⚓ Biden_Administration_Caught_in_Lie_Over_Student_Debt Forgiveness_Memo⠀⇛ # ⚓ Opinion_|_The_Super-Rich_Have_Taken_Almost_All_of_It⠀⇛ They should pay something back to the society that made their unprecedented wealth possible. # ⚓ Biden’s_‘Global_Tax’_and_the_40-Year_US_Corporate_Tax ‘Shell Game’⠀⇛ But why is the mainstream media bringing it up again now? Is it to soften the blow of Biden’s repeal of his proposal to hike corporate taxes in the US from Trump’s 21% to 26%? (It was 35% pre- Trump)? Or is there something else as well that explains why the media is running the global tax story that’s already weeks old? The global sign on to Biden’s 15% global minimum tax, announced weeks ago, is purportedly designed to prevent big multinational corporations’ manipulating governments by seeking out, and getting, special tax deals in certain countries at the expense of others. o § AstroTurf/Lobbying/Politics⠀➾ # ⚓ ‘Troubling’_Survey_Finds_Violent,_Anti-Democratic_Views Thriving_on_American_Right⠀⇛ “I’ve been doing this a while, for decades, and it’s not the kind of finding that as a sociologist, a public opinion pollster, that you’re used to seeing.” # ⚓ The_New_York_Times_Nominates_Bob_Gates_to_Save_the_Biden Administration⠀⇛ Gates’ deceitful record has not always been in the public view, but there is sufficient evidence of a bureaucratic career devoted to reckless self- promotion.  In 1987, President Ronald Reagan nominated Gates to be the successor to the late William Casey as director of central intelligence.  Gates had to withdraw his name from the confirmation process because the chairman of the Senate intelligence committee, David Boren (D-Ok), told him that the committee didn’t believe his claim to have no involvement with the Iran-Contra scandal. Boren even called Lawrence Walsh, the independent counsel investigating Iran-Contra, to ascertain whether Gates would be indicted.  Walsh “doubted Gates’ veracity,” but said he would “probably not” be indicted. In 1991, President George H.W. Bush nominated Gates for a second time and, despite testimony from senior CIA officials regarding Gates’ role in Iran- Contra, he survived unprecedented opposition to serve the shortest tour of duty of any CIA director in history.  President Bill Clinton ignored Gates’ pleas to remain at CIA. # ⚓ Republican_Poll_Watchers_Make_Their_Return_in_Virginia Gubernatorial_Race⠀⇛ # ⚓ Poll_Shows_O’Rourke_Ties_Abbott_in_Hypothetical_Race_for Texas_Gov._Next_Year⠀⇛ # ⚓ Voter_Suppression_Isn’t_Just_a_Problem_Down_South⠀⇛ We face so many issues as a state and as a nation, but few are more important than protecting our right to vote. A wave of voter suppression is spreading across the country, specifically targeting Black, Latinx, and Native voters. Our elders bled in the streets to make sure we could have a voice in our democracy, but even in a state as blue as New York, it’s still far too hard for many people to cast their ballot. # ⚓ ‘Manchin_Is_a_F**king_Snake’:_Progressives_Urged_to_Keep Pushing_for_Both_Bills⠀⇛ Supporters of passing the Build Back Better budget reconciliation package urged congressional progressives to maintain their position that it must move forward simultaneously with bipartisan infrastructure legislation after Sen. Joe Manchin accused his colleagues of holding the latter bill “hostage” and demanded an immediate vote. During a Monday press conference, Manchin (D-W.Va.) said that “the political games have to stop” and called for the Democrat-held U.S. House of Representatives to swiftly vote on the infrastructure bill—which several Senate Democrats advanced in August with the expectation that it would only reach President Joe Biden’s desk alongside the reconciliation package. # ⚓ Manchin_Claims_Others_Won’t_Compromise_After_Forcing Reconciliation_to_be_Halved⠀⇛ # ⚓ Lee_Camp:_The_Four_Layers_of_Reality_—_and_Why_We’re_Only Allowed_to_Talk_About_One⠀⇛ No matter which mainstream media segment you’re currently watching, I can promise you it’s not getting to the heart of any issue. By definition they only participate in surface level analysis. For example, there are three or four levels of reality we should be discussing when we talk about any United States election. And by “discussing,” I mean “screaming about,” and by “screaming about,” I mean “freaking out about.” So, let’s freak out – shall we? # ⚓ Meet_the_Socialist_Candidate_for_NYC_Mayor⠀⇛ “This is not a socialist country; let’s be clear on that,” said Brooklyn Borough President Eric Adams, the Democratic nominee for mayor of New York City, on Real Time With Bill Maher in July, following a hotly contested Democratic primary. Throughout his campaign, Adams has made it abundantly clear that he is not aligned with the left. Indeed, just a few days before the Maher interview, he took a swipe at supporters of democratic socialism by announcing, “I’m no longer running against candidates. I’m running against a movement,” referring to democratic socialist activists in New York and nationally. o § Misinformation/Disinformation⠀➾ # ⚓ It’s_Ridiculous_The_‘Developing_World’_Wasn’t_Given_Access To_The_Facebook_Files⠀⇛ By now it’s fairly clear the Facebook leaks showcase a company that prioritized near-mindless international growth over the warnings of their own experts. They also show a company that continues to painfully struggle to be even marginally competent at scale, whether we’re talking about content moderation or rudimentary customer service. While this has become an all-encompassing media spectacle, the real underlying story isn’t particularly unique. It’s just a “growth for growth’s sake” mindset, where profit and expansion trumped all reason. It just happens to be online, and at unprecedented international scale. # ⚓ Facebook:_From_the_Shallow_End_to_the_Deep_(But_Not Really)⠀⇛ And I don’t even have an active account. Sick of hearing about Likes. Sick of seeing folks everywhere scrolling in mid-feeds like chattel cattle. Sick of timelines that Ed Snowden sees as part of the Permanent Record that will one day contain evidence of our criminality, retroactively, and by algorithmic policing. It’s depressing: I know lots of good people who have such oxycontin- like accounts and I worry that by the time they discover “It’s a Cookbook,”(*) they’ll already be on their way to the intergalactic rotisseries (humans apparently taste like chicken: finger lickin’ goodness). Fuck Facebook. Meta as opposed to physical. Face, facetious, fecetious, facile, Facebook. Skin deep goes deep skin. Meta. Physical. Metaphysical. Beyond the mere biologicality of our physical beings is a metacognition, a consciousness of being, a transmigration of hive-minded souls to a Neurana existence. The bliss of the one and many rivers. But it’ll be the same old tappy-tap of fingers dancing on the keyboard The June Taylor Dancers, no doubt bringing new rushes of feralmoans and standing ovulations, but the same loneliness of the many folded into the one. You. Remember how sad and washed out they looked in last year’s Oscar-winning film, Nomadsland, Frances McDormand migrating from region to region, catching up with fellow free migrants at campsites in the middle of desert landscapes for pep talks, transferring her work from one Amazon Fulfillment Center to another? No? Keep the line moving, they say in baseball lingo — or you’re fired, they say in Amazon lingo. Cancelled, in the parlance of our day. o § Information/Freedom of the Press⠀➾ # ⚓ Justice_For_Julian_Assange_Is_Justice_For_All:_John Pilger⠀⇛ While Julian Assange endures an endless prison sentence for revealing atrocities perpetrated on innocents during the West’s endless wars, John Pilger turns his gaze to some of the officials, journalists and media outlets who have aided and abetted one of modern history’s greatest and most public episodes of torture. # ⚓ John_Pilger:_Justice_for_Assange_is_Justice_for_All⠀⇛ When I first saw Julian Assange in Belmarsh prison, in 2019, shortly after he had been dragged from his refuge in the Ecuadorean embassy, he said, “I think I am losing my mind.” # ⚓ The_CIA,_Empty_Assurances_and_Assange’s_Defence⠀⇛ The morning session was focused on defending the action of the defence witness Michael Kopelman, whose initial psychiatric assessment of Assange’s wellbeing omitted reference to Stella Moris and the existence of their two children.  The prosecution had contended that this impaired Kopelman’s partiality before the court, notwithstanding his correction to the account in the final court submission.  The omission, Fitzgerald contended, was justified given fears of the surveillance operation in the Ecuadorian embassy mounted by the Central Intelligence Agency, and concerns about potential abduction and assassination.  This point had been confirmed in the now famous Yahoo! News report. A day prior to the submission of the initial report, Kopelman had sought legal advice from the head of the solicitor’s firm acting for Assange, Gareth Peirce.  But as Peirce was facing an avalanche of documents to be served at the time – surveillance, allegations of kidnapping and poisoning, among other things – she was unable to furnish him with timely advice.  Baraitser duly found that Kopelman’s conduct, while misleading, was not that of a dishonest individual but “a very human response”.  The judge also knew about the identity of Moris prior to reading the initial report. o § Civil Rights/Policing⠀➾ # ⚓ Hawaii_School,_Police_Department_On_The_Verge_Of_Being_Sued For_Arresting_A_Ten-Year-Old_Girl_Over_A_Drawing⠀⇛ Putting cops in schools is never a good idea. It only encourages school administrators to hand over discipline problems to the “proper authorities,” which is what administrators used to be until the addition of law enforcement on campus. # ⚓ ‘Stakes_Could_Not_Be_Higher’:_With_Roe_in_Danger,_Coalition Demands_Supreme_Court_Expansion⠀⇛ “It should frighten all of us that the Supreme Court is actively attacking settled constitutional doctrine to achieve partisan political outcomes.” # ⚓ The_Erosion_of_Roe_v._Wade_and_Abortion_Access_Didn’t_Begin in_Texas_or_Mississippi:_It_Started_in_Pennsylvania_in_1992⠀⇛ The court is set to weigh in on abortion restrictions from at least two states this term. The first is a Texas law effectively outlawing abortions after six weeks. The second is a Mississippi law barring abortions after 15 weeks. On Oct. 22, 2021, the Supreme Court upheld a Fifth Circuit Court of Appeals ruling allowing the Texas law to go into effect while the case is being litigated. # ⚓ While_Supreme_Court_Weighs_Texas_Abortion_Ban,_Senate_Dems Urged_to_Kill_Filibuster⠀⇛ As the U.S. Supreme Court on Monday heard oral arguments about a “dangerous and dystopian” abortion ban in Texas, Senate Democrats faced fresh calls to abolish the filibuster, an outdated rule that has impeded the party and President Joe Biden’s agenda. Although Vice President Kamala Harris is responsible for tie-breaking in the evenly split Senate, the chamber’s makeup and the filibuster mean that many bills are blocked from being debated, let alone receiving a final vote. # ⚓ 2_Conservative_Justices_Hint_at_Letting_Challenge_to_TX Abortion_Law_Go_Forward⠀⇛ # ⚓ When_Critical_Race_Theory_Met_the_CFPB…_at_a_Toyota Dealer⠀⇛ When Rohit Chopra was still a commissioner at the Federal Trade Commission, in May of 2020, he issued a forceful public statement following an investigation into the racist lending practices his agency uncovered at a Bronx auto dealership. Chopra highlighted that the case hinged on subtly discriminatory “disparate lending” practices as he urged the FTC to ramp up its activity in that area. Chopra reminded his colleagues that in 2010, Congress passed legislation to enhance the FTC’s investigation and enforcement capacity in the auto industry—but that the agency had not leveraged the congressional activity into action. “Given the difficulty of uncovering direct evidence of discriminatory intent,” Chopra wrote, “disparate impact analysis is critical for detecting potentially unlawful discrimination.” # ⚓ How_Thousands_of_Black_Farmers_Were_Forced_Off_Their_Land⠀⇛ In 1883, less than 20 years after emancipation, Curtis Gentry bought nearly 1,500 acres of undeveloped land in Shiloh, a rural community in the Alabama county where he had once been enslaved. Alongside his brother Turner, with whom he was able to reunite after emancipation—unlike the members of so many other Black families—Gentry cleared that property, uprooting trees, brush, and undergrowth. Once the land was arable, he planted and harvested an array of crops, including ribbon cane, corn, and peas. “He was a hard worker,” Bernice Atchison, Gentry’s granddaughter-in-law, told me. “Not only did he clear his own land, but he took jobs helping white people clear their land.” He taught his family how to take care of the farm while he worked on other people’s farms, bringing in extra money to the household. # ⚓ LA_Inspector_General_Looks_Into_Allegations_of_Racist Policing_by_Sheriff’s_Deputies_on_School_Grounds⠀⇛ Los Angeles County’s Inspector General is looking into allegations of racial discrimination raised by an LAist-ProPublica investigation on high school campuses in the Antelope Valley. Priscilla Ocen, chair of the Sheriff Civilian Oversight Commission, asked Inspector General Max Huntsman’s office to explore our finding that in 2019, LA sheriff’s deputies disproportionately stopped and cited Black teens at high schools in Lancaster. o § Internet Policy/Net Neutrality⠀➾ # ⚓ Senate_Must_Confirm_Biden’s_FCC_Picks_to_Ensure_Open_and Affordable_Internet⠀⇛ # ⚓ Lessons_From_The_First_Internet_Ages⠀⇛ On Tuesday and Wednesday of this week I’m excited to be participating in an event that the Knight Foundation is putting on, curated by law professors Eric Goldman and Mary Anne Franks, entitled Lessons From the First Internet Ages. The event kicks off with the release of reflections on “the first internet age” from various internet luminaries who were there — but also, most importantly talking about what they might have done differently. I’m going to have a writeup at some future date on my response to the pieces, but I highly recommend checking them all out. In particular, I’ll recommend the pieces by Senator Ron Wyden, Nicole Wong, Brewster Kahle, Vint Cerf, Reid Hoffman, and Tim Berners-Lee. I also think that the interviews Eric Goldman conducted with Matthew Prince and Nirav Tolia were both fascinating. # ⚓ Internet_shutdowns_are_a_political_weapon._It’s_time_to disarm.⠀⇛ # ⚓ Slowdowns_and_shutdowns:_Africans_challenge_internet restrictions⠀⇛ Telecommunications were interrupted in Sudan this week after the army seized power in a coup, the latest in a string of internet outages in African countries … # ⚓ Why_are_Google_and_Apple_still_silent_on_Russian censorship?_|_Internet_|_Al_Jazeera⠀⇛ The two tech giants need to be transparent on why they caved in to Russian pressure to censor an opposition app. # ⚓ [Revealed]_Udaipur_Internet_Shutdown_Orders:_Cut,_Copy, Paste!⠀⇛ Recently, an Internet shutdown has twice been imposed in Rajasthan to prevent cheating in exams. So, we filed Right to Information applications to determine the extent of compliance with directions in Anuradha Bhasin. We found that the office of the Udaipur Divisional Commissioner has issued 26 internet shutdown orders, most of which are similar! The orders followed a template format – (i) a bureaucrat recommends suspension of internet services citing ‘law and order’ concerns; (ii) the Divisional Commissioner expresses their satisfaction with the recommendation without providing any reasoning; and (iii) the Divisional Commissioner suspends internet services under Telecom Suspension Rules. # ⚓ actcheck!_The_IT_Rules_2021_FAQ⠀⇛ ‘The Union Government had notified the Information Technology (Intermediary Guidelines and Digital Media Ethics Code) Rules, 2021 in February, 2021 (‘the Rules’). Back then, we provided a deep-dive of the Rules and thereafter, they have been subject to several challenges. The High Court of Madras and Bombay have stayed Part III of the Rules. Now almost 8 months after the notification of the Rules, the Ministry of Electronics and Information Technology has released a document consisting of Frequently Asked Questions purportedly to ‘bring clarity’ and to ‘explain the nuances of the due diligence to be followed by intermediaries’. In this blogpost, we separate the Facts from the Claims made in the FAQ document. o § Digital Restrictions (DRM)⠀➾ # ⚓ Why_Hollywood_Sucks:_Third_Time’s_a_Charm_with_“Dune”?⠀⇛ Now, nearly twenty years after The Fellowship of the Ring’s release, which struck the mold of multi- film franchises that have been the mainstay of American cinema in this young century, Warner Bros. has released a proper adaptation of Herbert’s novel. Directed by Denis Villeneuve, the picture is intended to be the opening of a new trilogy, with Part II covering the second half of the gargantuan source novel and Part III adapting the much tinier but far more frightening sequel Dune Messiah. Set 8,000 years hence in a neo-feudal galactic empire, the story follows the young noble-born Paul Atreides as he begins a life-changing journey on the desert planet Arrakis, the only source of the all-important geriatric spice melange, which allows space travel and prolongs lifespans. To say the story is laced with analogies about the Middle East and fossil fuel geopolitics is an understatement. This was the third time that the book was adapted and considering each of these attempts is a fascinating exercise in cinema history. # ⚓ Beyond_Right_to_Repair_–_Purism⠀⇛ Pick a random consumer device lying around your house and imagine someone coming across it after 70 years of neglect. Part of the device no longer works. Would they be able to fix it? Today, devices are designed to be cheap, short- lived and disposable. The assumption is that if something you buy breaks, the only solution is to throw it away. Repairability and longevity is simply not a factor in most consumers’ minds. In fact, this “use and throw” mentality contributes to massive e-waste. The total e-waste around the world this year is estimated to reach a record 57.4 million tonnes–that is, more than the weight of the Great Wall of China Being able to repair things we own is critical to extending their longevity. This past week the Library of Congress approved changes to the Digital Millenium Copyright Act (DMCA) that grant people the right to get into their consumer devices for the purposes of diagnostics, repair, and maintenance. This is part of an overall initiative to expand the so-called “Right to Repair” nationally within the US (there are similar efforts in the EU). The core idea behind Right to Repair is to prevent companies from using the DMCA or other means to block consumers from being able to take apart, reverse engineer, and repair things they buy. Removing the legal risk is a big step forward, but we must move beyond the Right to Repair before the devices you buy are actually repairable. In this post I will elaborate on the problem of longevity in modern devices and some solutions. It starts with parts and ends with software. o § Monopolies⠀➾ # § Patents⠀➾ # § Software Patents⠀➾ # ⚓ SUSE_Joins_LOT_Network_to_Protect_Open Development_and_Innovation [Ed: It is a patent pool, and it does not do what SUSE claims that it’ll do [1, 2]]⠀⇛ Today, SUSE joins LOT Network, a global community of more than 1,700 organizations who have collaboratively immunized themselves and helped protect customers from the negative effects of opportunistic patent trolls. Each of the companies in this community has pledged to ensure that any patents they transfer to non-practicing entities (NPE) do not pose a danger to the rest of the LOT community or any of their customers.

Publishers can’t go back in time to change history (fortunately). But the COVID pandemic, which largely stopped people borrowing physical books, presented publishers with a huge opportunity to make the lending of newly-popular ebooks by libraries as hard as possible. # ⚓ Digital_Democracy_from_the_‘Global_Britain_for_an open_world?’_publication⠀⇛ For digital democracy to succeed across the world, we need an open reformation in our democratic systems, practices and mindset.

In the public and private cloud, and from the enterprise to startups, the majority of IT executives around the world have explored Kubernetes, and how it has evolved the way many organisations are developing and deploying their applications. But what is scary about it, and how can organisations better leverage one of the greatest tools in the field while overcoming the biggest challenges facing CIOs when adopting Kubernetes? [...] Containers introduced a modern way to virtualise infrastructure that is more lightweight and focused on the cloud-native applications era. It allows users to divide up machines so that they can run multiple applications or OS instances on the same kernel and hardware while maintaining isolation among workloads. This ensures greater resource utilisation and shorter startup times by several orders of magnitude. Kubernetes, being the most widely used container orchestration tool, has largely simplified how organisations use containerised platforms for their applications. o § Audiocasts/Shows⠀➾ # ⚓ My_NEW_Channel_with_@The_Linux_Experiment!_–_Invidious⠀⇛ I am THRILLED to announce a brand new collaboration featuring the amazing Nick from @The Linux Experiment!

Notable this pull request is the cluster-aware scheduling support. The cluster scheduler support new to Linux 5.16 allows for enhancing the CPU scheduler’s behavior for x86_64 and AArch64 having clusters of CPU cores that share an L2 cache or other mid-level resources. The work was started to improve select 64-bit ARM SoCs like the Kunpeng 920 server chip with clusters of cores sharing an L3 cache. With the scheduler aware of the cluster topology it was able to make better scheduling decisions that improved the overall performance and efficiency of the system. # ⚓ Microsoft_Begins_Landing_Hyper-V_Isolation_VM_Support_In Linux_5.16_–_Phoronix⠀⇛ Microsoft has submitted their set of Hyper- V hypervisor updates today for the Linux 5.16 merge window.

ROCm 4.5 brings with it a number of new features and improvements but one area on the consumer Radeon side will leave some potential users frustrated. First up when it comes to installing ROCm 4.5, they have added support for using the amdgpu-install / amdgpu-uninstall scripts just like the Radeon Software for Linux packaged driver. The amdgpu-install-based process aims to streamline the Radeon Open Compute install process and make it just like installing the packaged driver driver. It also makes it easy to uninstall too. o § Instructionals/Technical⠀➾ # ⚓ Pi-Hole_Update_Troubles_–_CubicleNate’s_Techpad⠀⇛ In all the hustle and bustle this year, I haven’t really made any blatherings here about the joys of using the Pi-Hole on my network-wide ad blocker. I installed this the “easy way” on a Raspberry Pi running Raspberry Pi OS. Since there isn’t a version that I can easily and quickly install on openSUSE, I went for the method I could deploy the quickest. I can testify that the Pi-Hole has been great, and more on that at another time. For some time, the Web Interface was telling me that there was an upgrade available and since there wasn’t an easy button to make it happen, I put it off. Unfortunately, it wasn’t as easy as a remote secure shell into it and performing the update as written. # ⚓ Use_any_Linux_applications_through_a_proxy_(apt-get,_wget etc)_–_blackMORE_Ops⠀⇛ It’s pretty normal in many Organizations to use get servers to connect to Internet via a Proxy. In most cases it’s for updating apt-get or yum via proxy. However, quite often you might need to download packages directly using wget or curl and setting up apt-get or apt via proxy, wget via proxy, curl via proxy is a pain. What if you could simply setup a Proxy and just use any applications to use that using a simply command? I faced this many times and hence writing this guide. Note that if you’re only allowing apt-get via proxy then stick with configuring /etc/apt.conf or /etc/apt/conf.d/ 00proxy or something similar but if you need to allow different applications via a proxy then this method is best and simplest. # ⚓ A_Complete_Guide_to_Integrating_SUSE_Rancher_with_vSphere using_Terraform_on_phoenixNAP⠀⇛ # ⚓ Master-Master_replication_with_MariaDB_–_Unixcop_the_Unix_/ Linux_the_admins_deams⠀⇛ A couple of days ago I wrote a tutorial on how to do replication with MariaDB (or MySQL). This is a one-way replication: from master to slave; this means that the slave server receives the transactions form the master. But my client needs bidireccional replication, because we don’t know which server will receive the transaction and the same data has to be on both. Here I will show you how to configure master-master replication with MariaDB to achieve this. # ⚓ Introduction_Portainer_is_a_program_that_helps_you…⠀⇛ Portainer is a program that helps you manage your docker containers. If you want to delete , stop, or restart a docker container; you can easily do so with the portainer user interface (rather than going SSH and typing all kinds of commands). You can adjust containers settings, manage resource, and manage from within inside the container to gain perspective. Just think of Portainer as the GUI version to manage your containers compared to using CMD Line; while having powerful functions such as replication or amending containers on the go! Also Portainer enables centralized configuration, management and security of Kubernetes and Docker environments, allowing you to deliver ‘Containers- as-a-Service’ to your users quickly, easily and securely. In this article, we will install Portainer with Docker in CentOS 8 # ⚓ Check_Contrast_between_Two_Colors_in_Ubuntu_Linux_via Kontrast_|_UbuntuHandbook⠀⇛ For designers want to check color contrast, there are a few handy little tools in Linux Desktop to do the job. Kontrast is the one designed for KDE though works on all Linux desktops. GNOME has a stylish color contrast tool. Though it’s now in early stage which does not work well and freezes often at least in my case. Here I’ll introduce the KDE’s Kontrast. # ⚓ What_Are_IP_Addresses:_Basic_Concepts_and_Terms_Explained_ (Versions,_Type,_Subnetting,_Ports)⠀⇛ If you’re reading this article, chances are, you’ve come across many different terms associated with the IP address on the internet. In this article, we will cover the basic concepts and terms related to IP addresses that you’ve been wondering about. We will also explain how IP addresses work and where they fit into the big puzzle of the internet. # ⚓ How_to_Install_MongoDB_on_Rocky_Linux_8_–_VITUX⠀⇛ MongoDB is a free and open-source document-oriented database. Unlike relational databases, which store data in tables and require predefined schemas before adding new data, documents in MongoDB are unordered collections of key/value pairs with dynamic schemas (i.e., no fixed schema). As such, the same field can hold an integer, a string, or an object — it just depends on what you need for your application. Moreover, due to its dynamic nature, MongoDB works very well for storing JSON objects, making it great as a RESTful database. While MongoDB supports secondary indexes, they are not required for every scenario. This means that reads may be slightly slower with MongoDB than some relational databases (because you need to read more fields from disk), but writes are generally faster because there is no index maintenance involved. MongoDB is useful for any Linux user who needs to store and manage data (relational and unstructured), especially when you need scalability or high availability. The main reason that MongoDB is growing in popularity is that it provides the ability to store JSON documents, making it a great fit for hybrid Web applications that are used by both mobile clients (e.g., iPhone) and traditional desktop browsers (e.g., Firefox). Because these applications serve multiple client types with different data storage requirements, MongoDB can be an ideal fit because its schema-less design supports the dynamic nature of the data in these modern Web apps. # ⚓ How_to_Install_DokuWiki_with_Apache_on_Debian_9⠀⇛ This tutorial I will show you how to install and configure the latest version DokuWiki CMS platform on Debian 9.2 release, in order to create online documentation websites. DokuWiki is a free open source wiki application written completely in the PHP programming language and often deployed in Linux under Apache/Nginx web servers and PHP. DokuWiki software platform requires no RDBMS SQL database to run. In exchange, it uses simple plain text files as backend in order to store all data. DokuWiki is a simple and flexible platform with a clean syntax that can be successfully used to deploy powerful and collaborative documentation websites. # ⚓ How_to_create_a_Network_Load_Balancer_on_AWS⠀⇛ Load Balancer falls under the EC2 service of AWS. A Network Load Balancer works at the fourth layer of the Open Systems Interconnection (OSI) model, the Transport Layer. It opens a TCP connection to the selected target on the port specified in the listener configuration. If there are unhealthy targets, then the Network Load Balancer stops routing requests to those unhealthy targets and starts sending the traffic to the healthy instances only in the same or different Availability Zone. Network Load Balancer supports static IP addresses, it allows registering targets by IP address i.e. targets outside the VPC of the load balancer can also be added, it scales to millions of requests per second. These are a few of the benefits of the Network Load Balancer. Network Load Balancer is also called a TCP Load Balancer as it works on TCP protocol. # ⚓ How_To_Install_MongoDB_on_Debian_11_–_idroot⠀⇛ In this tutorial, we will show you how to install MongoDB on Debian 11. For those of you who didn’t know, MongoDB is a NoSQL database that is simple, object-oriented, scalable, and dynamic database. It is also called a NoSQL database because it does not rely on a traditional table-based relational database structure. It stores data in JSON format instead of the table style method. It can be integrated easily with various programming languages. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by- step installation of the MongoDB NoSQL database on a Debian 11 (Bullseye). # ⚓ How_to_install_Ruby_on_Rails_on_Rocky_Linux_8⠀⇛ In this tutorial guide we are going to install and configure Ruby on Rails on Rocky Linux 8. Ruby on Rails is a server-side web application framework written in Ruby under the MIT license. Rails is model-view-controller framework providing default structures for databases, a web service and web pages. Ruby on Rails is used by notable organizations such Airbnb, GitHub, crunchbase, Bloomberg etc Ruby on Rails is open source web development framework suitable for building dynamic web pages. Rails stands out among other web development frameworks because of its elegance, power and integrated approach to web applications. # ⚓ Chromium_Blog:_Run_on_OS_Login [Ed: Except you cannot turn on all the Google spyware inside every corner of this OS and browser (they try to blur the differnece)]⠀⇛ Users want frequently used applications such as Email, Chat, and other productivity apps to automatically start when they log in to their devices. Auto-starting these apps at login streamlines the user experience as users don’t have to manually start apps after logging into their devices. o § Games⠀➾ # ⚓ Humble_Choice_for_November_has_Project_Wingman,_WRATH:_Aeon of_Ruin_plus_more_|_GamingOnLinux⠀⇛ The latest bundle of games is now available for the subscription service Humble Choice (formerly Humble Monthly) and it seems like quite a varied selection. Here you pay for whatever tier you feel is the best value to get access to the Humble Trove (a ton of DRM-free games), a discount at the Humble Store and the ability to claim Steam keys (sometimes GOG keys) for multiple titles – the amount of which depends on what tier you buy into. As usual we shall tell you how you can expect each to run on Linux. o § Desktop Environments/WMs⠀➾ # § K Desktop Environment/KDE SC/Qt⠀➾ # ⚓ KDE_PIM_in_September_and_October⠀⇛ In the months since the KDE PIM July-August report there have been two patch releases for Kontact, and over 1400 changes made by more than 40 contributors have been integrated. Here are some of the highlights. KOrganizer A lot has happened over the last two months in KOrganizer development. First of all, Friedrich has been working on reviving the calendar decoration feature. This feature was introduced in 2007, but has since suffered from a lack of maintenance and multiple regressions. Decorations allow you to display additional information inside the week view. Here is what it looked like back in 2007 when it was introduced. o § Distributions⠀➾ # § New Releases⠀➾ # ⚓ Makulu_Droid_New_ISO_Available._–_MakuluLinux⠀⇛ We have Updated the MakuluLinux Droid ( android ) ISO, the new ISO contains all the new patches and fixes that have been developed over the last 2 months. If you already have Makulu Droid installed you already have the patches and therefore do not need to reinstall, However new users will now have these patches and new features upon new installation. You can grab the Makulu Droid from the Main menu above or in the download section. # § IBM/Red Hat/Fedora⠀➾ # ⚓ Fedora_35_Released_for_Desktops_and_Servers._This_is What’s_New⠀⇛ Fedora 35 officially released for workstations, servers and spins. This release brings GNOME 41, KDE Plasma 5.23, new flavor and more. In this post we give you the things to look at and download/upgrade instructions. # ⚓ Fedora_Linux_35_Now_Generally_Available⠀⇛ The Fedora Project, a community-driven open source collaboration sponsored by Red Hat, Inc., today announced the general availability of Fedora Linux 35, the latest version of the fully open source Fedora operating system. The new features and enhancements in Fedora 35 are aimed at improving the overall experience for all levels of users – from beginner to advanced. This release continues the Fedora Project’s emphasis on delivering leading-edge open source technologies and includes updates spanning the Linux kernel to the desktop experience. Updates in Fedora 35 include… # ⚓ Fedora_35_released_[LWN.net]⠀⇛ The Fedora 35 release has been announced. # ⚓ WirePlumber_in_Fedora_35⠀⇛ Today marks an exciting day as Fedora 35 has now been released, with WirePlumber as the default session manager for PipeWire! Under development by Collabora since 2019, and previously adopted in the automotive space by Automotive Grade Linux, WirePlumber has now officially entered the linux desktop space and is the recommended session manager to accompany PipeWire, with other distributions expected to follow very soon. WirePlumber brings some new and interesting things to the desktop. Most notably, it introduces the ability to easily modify the overal behavior of PipeWire for different use cases, using Lua scripts. This allows power users as well as developers of use-case specific distributions or desktop environments to customize their multimedia experience and get the most out of PipeWire. Recently I gave a talk about how this Lua scripting mechanism works, which you can watch here. Additionally, WirePlumber comes with a library that provides a high level object model to interface with objects in PipeWire, enabling application developers to more easily integrate PipeWire control functionality into their applications. This can help in transitioning away from the PulseAudio API in the forthcoming future, as most graphical applications like desktop environment sound settings dialogs and mixer applications are still using the PulseAudio API to interface with PipeWire. # ⚓ Fedora_35_is_Here_and_Shines_with_the_New_GNOME_41⠀⇛ Fedora 35 is now officially available and brings with it the GNOME 41 desktop environment, which has plenty of great improvements as usual. After the release of the Fedora 35 beta at the end of September, Fedora 35 stable release is finally here with some exciting changes and improvements. This release continues the Fedora Project’s emphasis on delivering leading-edge open source technologies and includes updates spanning the Linux kernel to the desktop experience. # ⚓ Fedora_35_Debuts_With_GNOME_41_and_a_New_KDE_Variant –_It’s_FOSS_News⠀⇛ A couple of weeks after the beta release, Fedora 35 stable version has finally arrived! This version brings a few key improvements, many of which we will be looking at here. Most notable of these improvements is the inclusion of the recently-released Gnome 41, accompanied by smaller upgrades such as Linux Kernel 5.14 and the completion of the transition to PipeWire. Now, let’s have a look at some of these changes in brief along with some improvements introduced with Fedora 35. # ⚓ Openpower_Summit_2021 [Ed: POWER is not "open", so they need to rename this openwashing IBM event, where they recruit "followers" (slaves) for their so-called 'ecosystem' or 'community']⠀⇛ Last week I participated the OpenPower Summit. I enjoyed it, even if I was on sick leave with a fever. There were many interesting talks, ranging from open source and education through Power10 to instruction development. All sessions were recorded. Hopefully recordings will also be shared, as I did not have the strength to visit all the sessions I wanted. And, as usual, some of the interesting talks were given in parallel. # ⚓ Linux_Foundation’s_Open_Source_Climate_Welcomes Airbus,_EY_and_Red_Hat [Ed: Misuse of the “Linux” brand; Zemlin now profits (millions) by greenwashing some of the world’s biggest polluers, even military and Microsoft]⠀⇛ The Linux Foundation’s OS-Climate has announced that Airbus and EY have joined its cross-industry coalition seeking to accelerate the global transition to net zero through open data and open source decision- making tools for companies, investors, banks, and regulators. This follows the news in September that Red Hat (an IBM company) had joined and is contributing a world-class team of data scientists and developers to build the OS-Climate platform. Also announced is Airbus’ contribution of a scenario analysis modeling platform to analyze the clean energy transition. # ⚓ Self-healing_infrastructure:_A_closed-loop_automation blueprint⠀⇛ As modern digital infrastructure evolves towards cloud-native deployments and the hybrid multi-cloud, there is a growing need to simplify the operational complexity that results from the various layers of technology used in the process. Modernizing the digital infrastructure presents significant challenges to operations (Ops) teams. In the old days, an Ops team used to be able to identify problems occurring in a given datacenter—and easily narrow it down to one box running mainly one application—with the whole infrastructure/ application stack typically sourced through one vendor (sometimes two if the hardware is purchased separately). Today, with the evolution into the hybrid multi-cloud environment, infrastructure is sourced through multiple vendors (on-premise private cloud), and applications typically live in multi-tenant environments (public or private clouds). So while the cloud-native infrastructure itself provides better redundancy and high availability capabilities, applications and services are still subject to all types of failures and hence the need for closed-loop automation solutions, both at the application and infrastructure levels. # ⚓ Learn_to_develop_event-driven_applications_with Apache_Kafka_and_Red_Hat_AMQ_Streams⠀⇛ As technology evolves, dated infrastructures can wreak havoc on businesses looking to scale their systems and operations. It is critical to have staff on board that are equipped to support the transition from legacy software to a platform that can handle an organization’s modern workload. Many organizations turn to microservices to increase scalability, time to market and DevOps agility. While delivering on these promises, microservices architecture brings its own complexities to the table. Red Hat Training is dedicated to helping organizations and individuals develop and troubleshoot these applications using tools such as Apache Kafka and Red Hat AMQ Streams. We recently introduced a new training course, Developing Event-Driven Applications with Apache Kafka and Red Hat AMQ Streams (AD482), which teaches fundamental principles and features of these tools. # ⚓ Red_Hat_and_Intel_Collaborate_to_Advance_Industry_4.0 Ecosystem⠀⇛ Red Hat and Intel are extending our long- standing collaboration to bring Industry 4.0 transformation to smart manufacturing and energy. By bringing together Red Hat’s expertise in open source software and Intel’s leading hardware architecture and software toolsets, we believe we can accelerate the efforts underway in the Industrial Control Systems (ICS) ecosystem across a range of use cases – thereby accelerating IT/OT transformation. # § Debian Family⠀➾ # ⚓ Pnmixer_replaced_by_volumeicon⠀⇛ Pnmixer is not really a mixer, it is an alsa audio volume slider control for the systray. On my Lenovo PC, it has a “mute” checkbox that remains always ticked, even when audio is working. So, I have looked at alternatives… As Easy 3.1.3+ is now using pulseaudo and pipewire, I thought that a systray volume control designed to work with pulseaudio, rather than just alsa, would be the way to go. I found a couple; however, settled on ‘volumeicon’, which is only an alsa volume control. # ⚓ Latest_libcamera_and_pipewire_compiled [Ed: Pipewire is about Red Hat leading the way]⠀⇛ I had previously compiled meson 0.59.2 in OE, then rolled back to 0.53.0, however, I did keep the 0.59.2 binary package, and have made it into a PET. That PET will be in the ‘devx’ SFS in the next release of EasyOS. With meson 0.59.2 in a running EasyOS, I was then able to compile the latest ‘libcamera’ and ‘pipewire’. I have done that, and made them into PETs. They also will be in the next release of EasyOS. Well probably, it depends how successful setting up pipewire is. I have got is basically working, that will have to be the subject of a later blog post. # ⚓ Initial_setup_of_pipewire⠀⇛ Pipewire does not replace pulseaudio, it uses the pulseaudio libraries. However, pipewire does completely replace ‘jack’. Pipewire has /usr/bin/pipewire-pulse, which is a daemon that replaces the /usr/bin/ pulseaudio daemon in the the pulseaudio package. I found that pipewire and pulseaudio must be configured to create a socket in the same path. So, if pipewire-pulse is running instead of pulseaudio daemon, applications such as ‘pavucontrol’ will recognise it. # ⚓ Debian_packages,_version_numbers_and_pre-release versions⠀⇛ Getting the latest version of a package into Debian involves checking when there are new versions available – fortunately (and not surprisingly) Debian has tools to make this simpler. I have recently ran into the problem when an upstream beta version sorts higher than a newer non-beta version. Which is problematic, of course. This is due to Debian sorting something like 1.0b as later than a pure 1.0 version. # ⚓ Thorsten_Alteholz:_My_Debian_Activities_in_October 2021⠀⇛ This month I accepted 341 and rejected 46 packages. The rejection is as high as last month. I hope everybody is aware that pressing just one key when accepting a package is much faster than writing an explanation why a package has to be rejected. Anyway, the overall number of packages that got accepted was 355. # ⚓ Paul_Wise:_FLOSS_Activities_October_2021⠀⇛ This month I didn’t have any particular focus. I just worked on issues in my info bubble. o § Devices/Embedded⠀➾ # ⚓ Adlink_reveals_two_Linux-driven_Coffee_Lake_systems_for autonomous_cars_and_C-V2X⠀⇛ Adlink unveiled a “AVA-3501” system used in the Indy Autonomous Challenge and announced a collaboration on 5G based C-V2X technology with Askey, III, and EOI using a similarly Ubuntu-on- Coffee Lake AVA-3510. Adlink also announced an edge visualization partnership with AUO. Adlink has ramped up its involvement in autonomous vehicles in recent weeks with announcements of collaborations with Indy Autonomous Challenge, as well as several other companies working on C-V2X (Cellular Vehicle-to-Everything) technology. Today, it followed up by announcing a collaboration with optoelectronic firm AUO on edge visualization technologies for a list of applications led by automated vehicles and autonomous robots. An Adlink/AUO virtual forum on the topic started today and will run through Nov. 4 (see farther below). # ⚓ MontaVista_Announces_Common_Criteria_EAL4+_Certification Readiness_for_Carrier_Grade_eXpress_Linux⠀⇛ MontaVista® Software, LLC, a leader in commercial Embedded Linux® products and engineering services, today announced the upcoming completion of a mission-critical project in the security certification-services area. # ⚓ Cherry_Pomodoro_Timer_Forces_You_To_Follow_|_Hackaday⠀⇛ If you have trouble staying focused and getting work done, the Pomodoro Technique of working in 25- minute intervals with 5-minute breaks is pretty hard to beat. The only problem is that it requires a lot of input from the user, and all that timer- setting can get in the way of actually getting down to business. The absolute worst is when you find yourself working hard, but see that forgot to set the damn timer (ask us how we know). In essence, the tomato itself can only do so much — you have to actually use it and honor the timer, put in the work, and believe in the system. # ⚓ 10-channel_floor_heating_valve_controller_supports_Tasmota, MQTT,_Home_Assistant_–_CNX_Software⠀⇛ Voltlog has designed an open-source hardware floor heating valve controller powered by an ESP32 WiFi module making it compatible with Tasmota open- source firmware, and by extension MQTT protocol and Home Assistant automation framework. The board can control up to 10 valves triac controlled outputs and spring connectors for a floor home heating system, and also offers a one- wire srping connector, an I2C header, and safety features with two fuses, although it’s obviously not UL nor TUV certified. # § Mobile Systems/Mobile Applications⠀➾ # ⚓ Android_12L:_Why_Google_must_lead_by_example_for_it to_succeed⠀⇛ # ⚓ Chromecast_volume_controls_are_disabled_on_Android_12 –_9to5Google⠀⇛ # ⚓ How_to_install_Android_12_Beta_on_Samsung_phones_– 9to5Google⠀⇛ # ⚓ Android_scam_apps_with_10_million_downloads_deleted by_Google_—_what_to_do_now_|_Tom’s_Guide⠀⇛ # ⚓ Swift_Backup_brings_rootless_file_backups_for_Android using_Shizuku_–_Android_Community⠀⇛ # ⚓ Android_Patches_Actively_Exploited_Zero-Day_Kernel Bug_|_Threatpost⠀⇛ # ⚓ Quest_2_Now_Shows_Pets,_People,_&_Android_Phone Notifications⠀⇛ # ⚓ Best_Android_app_deals_of_the_day:_Simple_Scan_Pro, and_more_–_9to5Toys⠀⇛ o § Free, Libre, and Open Source Software⠀➾ # ⚓ How_Purism_is_Pioneering_a_Bright_Future_–_Purism⠀⇛ There are a few things that make me proud of being part of the Purism team. One of them is the philosophy behind a company that makes respectful hardware and software, that is fully owned by the people using it. Another truly beautiful aspect of Purism (which I discovered over the years) is how Purism is a pioneer in hardware manufacturing. It has built a business model that creates relationships between the people who directly finance this Social Purpose Corporation. This way Purism avoids any potential conflict of interests from private entities. It gives back all the intellectual property of its research and development to the people. This is done through the use of public owned licenses, also known as the Free Licenses. # ⚓ Magama:_Open-source_mail_server_for_Linux⠀⇛ The Magama is an open-source mail-server application daemon for SMTP, POP, IMAP, HTTP, and MOLETN. It offers additional support for DMTP and DMAP. Magama features webmail with JSON-RPC interface, which requires some work to install. # ⚓ Inbucket:_A_disposable_Webmail_Server⠀⇛ Inbucket app is a free, open-source disposable mail server that works without any database. Inbucket supports many email protocols without depending on external dependencies. It accepts email and makes them ready via the web, and REST API. The system supports HTTP, SMTP, and POP3 out of the post. It offers multiple mailboxes’ management, attachment download, and a responsive simple web interface. # ⚓ Nextcloud_Announces_a_New_Backup_Application_for_Its_Home Users_–_FOSS_Force⠀⇛ Germany-based Nextcloud is releasing an easy-to-use backup application for its productivity and collaboration platform that’s designed not for the big enterprise customers who pay its bills, but for home users and small business who generally use the product for free. Announced today was Nextcloud Backup, a fully encrypted incremental backup solution that’s not only easy-to-use, but which offers a full set of features that includes a wide choice of backup options (including one that might surprise some folks) and the ability to search through a backup to find individual files and folders when a full restore isn’t needed. Nextcloud said that the software is aimed squarely at home users, along with small mom and pop sized businesses, which are unlikely to ever become paying customers, except for some who might pay a small amount for a hosted version. # ⚓ Nextcloud_Backup_App_Available_for_Beta_Testing⠀⇛ Last year, we mentioned Nextcloud as the swiss army knife of remote working tools, and rightly so. Nextcloud offers a lot of tools to help you build the ultimate collaboration tool while taking control of your data. Of course, if you are looking for convenience without the need for self-hosting, Nextcloud may not be an immediate option for you. However, if the lack of an easy-to-use backup tool was a deal-breaker for you, it might be a good idea to think it over. # § Web Browsers⠀➾ # § Mozilla⠀➾ # ⚓ Firefox_94_Released_with_Major_Performance Improvements⠀⇛ Mozilla Firefox 94 is now available to download. The latest update to the famed open source browser enables the OpenGL EGL backend by default under X11 for Intel. AMD and recent Mesa users (NVIDIA is still working to add support for EGL to its proprietary Linux driver). # ⚓ Firefox_94.0_and_Firefox_ESR_91.3.0_[LWN.net]⠀⇛ Firefox 94.0 has been released. Linux users should see improved WebGL performance and reduced power consumption for many workloads. The about:unloads page shows the user information about open tabs and allows them to release system resources by unloading tabs without closing them. Site Isolation provides better protection against side-channel attacks. See the announcement for more new features in this release. # § Productivity Software/LibreOffice/Calligra⠀➾ # ⚓ The_Month_of_LibreOffice,_November_2021_begins_–_Join in_and_get_cool_merch!_–_The_Document_Foundation_Blog⠀⇛ Love LibreOffice? Want to boost your skillset and learn new things? Then join the Month of LibreOffice! The software is a worldwide, community open source project – and many people who help to improve it, actually started out as regular users of the software. So in November, we want to encourage you to get involved, join our community, and have fun. You can build up valuable skills for a future career – and you don’t need to be a programmer. There are many ways to help make LibreOffice awesome, as we’ll see in a moment. # § Programming/Development⠀➾ # ⚓ GtkSourceView_is_getting_a_VIM_emulator_–_Zen_and_the Art_of_GNOME⠀⇛ One of the things we spent some time on early with Builder was creating built-in VIM emulation. Originally it was written in C, but then got converted to this nasty CSS for a couple of reasons. First, that keybindings in GTK 3 were largely done with CSS due to how we moved away from gtkrc in the 2.x to 3.x migration. And beyond that, CSS was the one way that’d let us share a lot of keybinding code between shortcut themes so we could support emacs, vim, sublime, etc. One thing that didn’t work well was VIM’s “modes”. People often think of VIM as a single state (normal, insert, replace, visual, etc). In reality it’s a stack of them. Just look at the following state diagram if you’re going to actually to match things somewhat accurately. Doing this in a manner that would allow sharing between shortcut themes in Builder was simply beyond the amount of time we had to spend on it given all the other features that needed to land. # ⚓ Stupid_RCU_Tricks:_Waiting_for_Grace_Periods_From_NMI Handlers_–_Paul_E._McKenney’s_Journal_—_LiveJournal⠀⇛ Suppose that you had a state machine implemented by NMI handlers, and that some of the transitions in this state machine need to wait for an RCU grace period to elapse. How could these state transitions be implemented? Before we start, let’s dispense with a couple of silly options. First, we clearly are not going to invoke synchronize_rcu() from within an NMI handler. This function can sleep, and we cannot sleep even within non-threaded interrupt handlers, let alone within NMI handlers. Second, we are not going to invoke call_rcu() from within an NMI handler. This function disables interrupts to exclude concurrent invocations on a single CPU, and disabling interrupts does nothing to keep NMI handlers from running. Worse yet, when running on rcu_nocbs CPUs (which offload callback invocations to rcuo kthreads), call_rcu() acquires a lock. Therefore, invoking call_rcu() from within an NMI handler would at best result in deadlock, and might also result in corruption of RCU’s lists of callbacks. # ⚓ “Ampere-1″_GCC_Patch_Posted_For_Ampere’s_Upcoming AArch64_Core_Design_–_Phoronix⠀⇛ While Ampere Altra and Altra Max processors are achieving great success using Arm Neoverse N1 based cores, as shared earlier this year Ampere has begun designing their own custom Arm server CPU cores for slated introduction in 2022. The first GCC compiler patch for that next-gen Ampere CPU was quietly posted on Monday. An initial patch made it out providing support and basic tuning for Ampere’s “Ampere-1″ CPU. Ampere-1 isn’t certainly the marketing name for their initial CPU core design but just what they are referring to at least initially for the GNU Compiler Collection target. Just as before IBM referred to their POWER10 GCC target as the ‘future’ target and then later on added in proper user-friendly string. # ⚓ An_Emulator_For_OBP,_The_Spaceflight_Computer_From The_1960s_|_Hackaday⠀⇛ [David Given] frequently dives into retrocomputing, and we don’t just mean he refurbishes old computers. We mean things like creating a simulator and assembler for the OBP spaceflight computer, which was used in the OAO-3 Copernicus space telescope, pictured above. Far from being a niche and forgotten piece of technology, the On-Board Processor (OBP) was used in several spacecraft and succeeded by the Advanced On- board Processor (AOP), which in turn led to the NASA Standard Spaceflight Computer (NSSC- 1), used in the Hubble Space Telescope. The OBP was also created entirely from NOR gates, which is pretty neat. One thing [David] learned in the process is that while this vintage piece of design has its idiosyncrasies, in general, the architecture has many useful features and is pleasant to work with. It is a bit slow, however. It runs at a mere 250 kHz and many instructions take several cycles to complete. # § Perl/Raku⠀➾ # ⚓ What_you_need_to_know_about_containers_for Python_|_Opensource.com⠀⇛ Python is a popular language for many applications. Those that run as backend services, now in the 2020s, are often run inside containers. For that to work, though, you have to build a container. Often, with microservice architectures, it makes sense to build a “root” base image, which all of your services get built on. Most of this article focuses on that base image since this is where it is easiest to make mistakes. However, I also cover the applications themselves because a good base without good applications isn’t of much use. # § Java⠀➾ # ⚓ NetBeans_»_PCLinuxOS⠀⇛ Quickly and easily develop desktop, mobile, and web applications with Java, JavaScript, HTML5, PHP, C/C++ and more. Updated to 12.3 # ⚓ Java_monitoring_for_custom_targets_with Cryostat⠀⇛ By default, Cryostat automatically recognizes discoverable, valid targets with remote Java Management Extensions (JMX) and JMX-RMI-enabled connectivity. Discoverability is based on various mechanisms, including Kubernetes API- based service endpoints and the Java Discovery Protocol (JDP). With Cryostat 2.0, developers can now create connections by providing custom URLs for known potential Java application targets that are valid but not yet discoverable. You can save custom target definitions so they are available even after the Cryostat instance restarts. This feature is available on the Cryostat web front-end through the Create Target functionality introduced in this article. Cryostat 2.0 also introduces the new clientlib directory.

Hive ransomware was first observed in June 2021, with the FBI warning about it in late August. Initially the ransomware targeted Windows only, but the creators are looking to expand that. # ⚓ Hive_Ransomware_now_Encrypts_Linux_and FreeBSD_Systems_–_IT_World_Canada⠀⇛ According to the Slovak Internet security firm ESET, the Hive ransomware gang can now encrypt Linux and FreeBSD with new malware variants that have been specially developed for these platforms. # ⚓ Hive_ransomware_group_extends_to_cloud- based_Linux_variants⠀⇛ # ⚓ What_Is_LemonDuck?_Cross-Platform_Mining Malware_That_Affects_Windows_and_Linux [Ed: Very old FUD back from the dead today, looking to associate "Linux" with dangers while actually Microsoft products are on fire everwhere]⠀⇛ The world of cybersecurity is forever evolving at a rapid pace. Newer and more sophisticated attacks are emerging every day. Despite patching most of these threats, some of them continue to crawl around the web a lot longer. LemonDuck is one such example. It’s a cross-platform malware that targets Windows and Linux devices and acts as an entry point for other malicious tools. So what exactly is LemonDuck? How does it work? o § Censorship/Free Speech⠀➾ # ⚓ Kazakhstan’s_plan_of_tech_platform_“localization”_opens door_to_censorship⠀⇛ A draft law in Kazakhstan would require foreign tech companies to open local offices and comply with content takedown demands within tight time frames, or have their services terminated. Advanced as a measure to protect children, the proposed law, “On Amendments and Changes to Legislative Acts on the Protection of the Rights of the Child,” is instead likely to undermine Kazakhs’ free expression and other human rights, and grant the government disproportionate censorship powers that are ripe for abuse. Access Now urges the Kazakhstan government to reject the proposal, as it fails to align with human rights principles. We provide a set of recommendations below for the government to safeguard Kazakhs’ freedom of expression and opinion, the right to access and disseminate information, freedom of association, and other rights protected under Kazakhstan’s constitution and international human rights law. [...] Finally, the implementation of staff and data localization laws in other countries has demonstrated the pitfalls of this approach. We have seen governments using such regulations to gain leverage over social media giants and force them to comply with state-sponsored censorship and surveillance. The recent removal of Alexey Navalny’s app from Google and Apple stores, reportedly triggered by the threats of criminal prosecution and armed raids at Google’s local subsidiary offices in Russia, is one example of how local staff can be used to pressure companies into removing certain content without due process and in violation of human rights. Civil society has also raised similar concerns regarding a recently passed Internet law in Turkey (Law No. 5651), which forces social media companies with more than one million “daily users” to comply with the government’s requests for content removal. This dangerous law gravely undermines freedom of expression in Turkey, particularly in the absence of an independent judiciary where such orders can be successfully challenged. ䷩ 𝚕𝚒𝚗𝚎 9575 ╒═══════════════════ 𝐃𝐀𝐈𝐋𝐘 𝐋𝐈𝐍𝐊𝐒 ═════════════════════════════════════════════╕ ⠀⌧ █▇▆▅▄▃▂▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁ 11.02.21⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▂▃▄▅▆▇█ ⌧ Gemini_version_available_♊︎ ✐ Links_2/11/2021:_FuguIta_7.0_and_MPV_0.34⠀✐ Posted in News_Roundup at 1:38 am by Dr. Roy Schestowitz 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇GNOME bluefish⦈ § Contents⠀➾ * GNU/Linux o Distributions o Devices/Embedded * Free_Software/Open_Source * Leftovers * § GNU/Linux⠀➾ o § Desktop/Laptop⠀➾ # ⚓ Chromebook_Linux_comes_of_age_|_ZDNet⠀⇛ Mind you, long before Google integrated Linux into Chromebooks, you could run desktop Linux distros on Chromebooks. With the open-source Crouton program and its chroot container, you could run Debian, Ubuntu, and Kali Linux. Or, you could run Gallium OS, a third-party, Xubuntu Chromebook-specific Linux distribution. Or, you could do what I’ve been doing for the last three years, just running Debian Linux using Google’s Crostini. This KVM virtual machine (VM) system with its LXD Linux containers may have been a beta but I never — I repeat — never had any trouble running Linux with it on all the many Intel-based Chromebooks I’ve used in the last few years. But, now that Linux is officially supported, you can run multiple Linux instances at once on your Chromebook. This will be a big deal. Do you want to compile your code in one container while playing Tux Racer in another? You can do that. Well, sort of. In practice, even on my maxed Pixelbook Go with its i7 processor and 16GBs of RAM, both containers stutter a bit. You see this feature is still a beta with a capital B. To make it work, you need to enable the new ‘crotini-multi-container’ flag. There’s also a new Chrome OS Settings section, “Manage extra containers”. This both tells you what your current containers are, lets you create a new one, and enables you to stop or delete your existing containers. In my early testing, I’ve been stopping a lot of misbehaving containers. In short, this new feature is far from ready for ordinary use. But, if you like playing on the bleeding edge of technology, it’s well worth a try. Eventually, when this new functionality is perfected, this will make high-end Chromebooks as useful for Linux power users as a top-of-the-line Linux laptop like a Dell XPS 13 Linux Developer Edition. o § Audiocasts/Shows⠀➾ # ⚓ The_More_You_Know_About_Technology,_The_More_You_Hate_It!_– Invidious⠀⇛ Recently, I’ve to the realization that I don’t love technology.

The kernel designates one release every year as an LTS release, which the developers and the community commit to maintain for at least two years. By this logic, Linux 5.15 will not reach end-of- life before October 2023. However, of late, the kernel has adopted a policy of supporting LTS releases for as long as its commercial users are willing to put up the required resources to maintain it. # ⚓ Linux_Kernel_5.15_is_Out!_Here’s_How_to_Install_in_Ubuntu⠀⇛ Linux 5.15 was released yesterday as the new Long Term Support (LTS) kernel release. Here’s what’s new and how to install in Ubuntu. Linus Torvalds announced the release of Kernel 5.15 on Sunday… # ⚓ Linux_5.15_Is_This_Year’s_LTS_Kernel_–_Phoronix⠀⇛ As we approach the end of the calendar year there was some uncertainty whether Linux 5.15 would be this year’s Long-Term Support (LTS) kernel or if it would be Linux 5.16 albeit not likely releasing until the start of 2022… Well, Greg Kroah-Hartman has decided on Linux 5.15 being the LTS kernel for 2021. The Kernel.org release page has been updated to reflect the newly- released Linux 5.15 kernel being an LTS branch. At the moment the LTS period projects Linux 5.15 LTS to be end-of-life in October 2023. However, as is usually the case, this can be extended by years given enough industry support. If enough users/ developers and organizations step up for committing to testing the new point releases and actually using the LTS kernel in production, the LTS period can be extended by several years. # ⚓ Neofetch_Command_in_Linux_(With_Examples)_–_Linux_Nightly⠀⇛ The neofetch command in Linux will output system information, distribution information, and an ASCII logo of the distro in terminal. The command is often seen in screenshots from users that wish to show off their system specs or the Linux distribution they’re using. In this guide, you’ll see how to install Neofetch on Linux, and use the neofetch command to see system information and get that cool screenshot you’re hoping to post somewhere. # ⚓ Linux_5.15_with_a_fresh_NTFS_driver_and_SMB_server_–_Market Research_Telecast [Ed: Automated translation]⠀⇛ During the night from Sunday to Monday, Linus Torvalds released version 5.15 of the Linux kernel. The new version is not just a maintenance release, but brings with it new features. The release offers a huge plus in the form of a new NTFS driver, especially for cross-platform data exchange with other systems. Other important innovations: Samba in the kernel and optimizations in the area of ​​the file systems. In the following, we take a brief look at the highlights mentioned in Linux 5.15. # ⚓ Linux_5.16_Loosens_The_Spectre_Defaults_Around_SSBD_/_STIBP –_Phoronix⠀⇛ Linux 5.16 is adjusting its default Spectre mitigation behavior around Spectre V2 for user- space tasks as well as Speculative Store Bypass Disable (SSBD) for Spectre V4 mitigation. Rather than the existing default behavior of applying the mitigations by default to all SECCOMP threads and those opting into those mitigations per-thread via the Linux kernel’s prctl() interface, with Linux 5.16 the default is being pulled back to just the prctl() opt-in behavior. This change has been talked about over the past year and previously covered within Linux Preparing To Slightly Loosen Its Spectre Defaults. # ⚓ 10_Interesting_and_Fun_Facts_About_Linux⠀⇛ Check out these surprising interesting facts about Linux and its comprehensive use today. If there is anything to add, feel free to share it in the comments.

It is secure, reliable, and runs in a multiuser environment for business and personal use. It saves passwords using bidirectional encryption with a master password to a database. It provides an intuitive web UI that helps you to set options like LDAP auth, mail, auditing, backup, import/export, etc. # ⚓ How_to_take_a_backup_of_an_Elasticsearch_cluster⠀⇛ The mechanism of taking backup in Elasticsearch is called Snapshot. A snapshot is a backup taken from an Elasticsearch cluster that is in a running state. There is no need to take down the cluster which helps avoid maintenance windows of the applications. A snapshot of an individual index or of the entire cluster can be taken and stored in a repository on a shared file system. Snapshots in Elasticsearch are taken incrementally. This means that when it creates a snapshot of an index, Elasticsearch avoids copying any data that is already stored as part of an earlier snapshot of the same index. Therefore it can be efficient to take snapshots of the cluster on a regular basis. In the same way we can take a backup of the cluster in running state, we can also restore a snapshot into a running cluster. When we restore an index, we can even alter the name of the restored index as well as some of its settings. # ⚓ Flatpak_Apps_Look_Out_of_Place?_Here’s_How_to_Apply_GTK Themes_on_Flatpak_Applications⠀⇛ One of the reasons why some users avoid installing Flatpak apps is that most Flatpak apps don’t change their appearance as per the current system theme. This makes the applications look out of the place in your otherwise beautiful set up. # ⚓ How_to_install_Ruby_Version_Manager_(RVM)_on_Debian_11 Bullseye⠀⇛ Ruby Version Manager is a command-line tool for installing & managing multiple Ruby interpreters and versions as well as gem sets simultaneously on the same computer.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by- step installation of the Telegram desktop on a Debian 11 (Bullseye). # ⚓ Automate_backup_Mysql_via_Cronjob_–_Unixcop_the_Unix_/ Linux_the_admins_deams⠀⇛ Hi guys ! In this write up, we will see how to automate the mysql backup using the cronjob. # ⚓ Ansible_loops_examples_and_introduction⠀⇛ In a previous article we talked about Ansible, a very useful provisioning free and open source software written in Python, which we can use to automate tasks on multiple machines. We saw how to install it on some of the most used Linux distributions and the basic concepts behind its usage. In this article we focus on how to use loops inside Ansible playbooks in order to perform a single task multiple times with different data. # ⚓ Configure_Veritas_Storage_CentOS_8_|_RHEL_8_step_by_step_– Unixcop_the_Unix_/_Linux_the_admins_deams⠀⇛ In this article mirrored filesystem will be configured, using storage local to each of the 3 nodes and shared with Flexible Storage Sharing (FSS). This filesystem will ensure that data will be available to all nodes in the cluster should a failover event occur. with use the space of a physical disk to build VxVM volumes, you must place the disk under Volume Manager control. Before a disk can be placed under Volume Manager control, the disk media must be formatted outside of VxVM using standard operating system formatting methods. SCSI disks are usually preformatted. After a disk is formatted, the disk can be initialized for use by Volume Manager. Disks must be detected by the operating system, before VxVM can detect the disks # ⚓ How_to_Install_Linux_Kernel_5.15_on_Ubuntu_and_Linux_Mint⠀⇛ Linux kernel 5.15 was released on Halloween, October 31st, 2021, and it brings some interesting new features, such as a new NTFS file system implementation that doesn’t require you to rely on third-party software like NTFS-3G to fully manage your NTFS formatted external disk drives. It also brings some new features for users of the Btrfs and XFS file systems, support for Nintendo Wii consoles, support for per-VLAN multicast, an in-kernel SMB server, a new r8188eu Realtek wireless LAN driver to replace the old rtl8188eu driver, and many other goodies. # ⚓ How_to_Install_Linux_Kernel_5.15_on_Rocky_Linux_8⠀⇛ Linux kernel 5.15 is out with many new features, support, and security. The Linux 5.15 kernel release further improves the support for AMD CPUs and GPUs, Intel’s 12th Gen CPUs, and brings new features like NTFS3, KSMBD (CIFS/SMB3), and further Apple M1 support, amongst many other changes and additions. In the following tutorial, you will learn how to install the latest 5.15 Linux Kernel on Rocky Linux 8. # ⚓ How_to_upgrade_Linux_Kernel_5.13_to_5.15_on_Ubuntu_21.10_– NextGenTips⠀⇛ In this tutorial we are going to learn how to upgrade Linux Kernel 5.13 to 5.15 on Ubuntu 21.10. Linux 5.15 mainline was released recently by Linux Torvalds with better new features to try out. Mainline tree is maintained by Linus Torvalds and It is where all new features are added and releases always comes from. # ⚓ SSH_Commands_in_Linux_with_Usage_Examples⠀⇛ SSH is a network protocol for securely logging into a remote machine and executing commands. It is designed and created to provide the best security when accessing another computer remotely. Whenever data is sent by a computer to the network, ssh will automatically encrypt it. To use SSH, the destination machine should have an SSH server application installed because SSH is a client-server model. An SSH server, by default, listens on the standard TCP port 22. SSH client is by default available on all Linux distributions. # ⚓ Docker_Compose_Up_vs_Start_and_Down_vs_Stop:_Differences Explained⠀⇛ These terms are enough to confuse a docker beginner because many of these docker-compose commands seem to behave in a very similar fashion. In fact, it can be especially difficult at first to right away tell the difference between docker- compose up and docker-compose start. Isn’t starting a container via Docker Compose the same as running the up command? Not exactly. # ⚓ Tutorial_on_Using_the_Timeout_Command_on_Linux_– LinuxStoney⠀⇛ A command timeout is a command line utility that executes a specified command and stops it if it is still running after a certain period of time. In other words, the command timeout lets you run the command with a timeout that you specify. The command timeoutis part of the core GNU utility package that is installed on almost all Linux distributions. This command is useful when you want to run a command that doesn’t have a built-in timeout option, or stop a process after a certain amount of time running. In this article, we will explain how to use commands timeout in Linux Terminal. # ⚓ Install_Portainer_with_Docker_on_Ubuntu_–_Unixcop_the_Unix /_Linux_the_admins_deams⠀⇛ Portainer is a program that helps you manage your docker containers. If you want to delete , stop, or restart a docker container; you can easily do so with the portainer user interface (rather than going SSH and typing all kinds of commands). You can adjust containers settings, manage resource, and manage from within inside the container to gain perspective. Just think of Portainer as the GUI version to manage your containers compared to using CMD Line; while having powerful functions such as replication or amending containers on the go! Also Portainer enables centralized configuration, management and security of Kubernetes and Docker environments, allowing you to deliver ‘Containers- as-a-Service’ to your users quickly, easily and securely. In this article, we will install Portainer with Docker in Ubuntu 20.04 o § Games⠀➾ # ⚓ You_Can_Play_Mario_Party_Superstars_Online_with_Ryujinx_on Linux_–_Boiling_Steam⠀⇛ Just a few days ago Mario Party Superstars was released for the Nintendo Switch. Of course, like with most new Switch games that come out these days, this game in particular has no problem running on either Ryujinx or Yuzu. Today (or yesterday, depending on your time zone) though, marks an update to Ryujinx’s LDN build — the build that allows fellow Ryujinx-ers to play games together via the game’s local wireless menu, whether you’re on Linux or Windows. The last time we got an update for this was the 2.3 version back in May. The 2.4 release improves the emulator quite a bit — it’s based on the latest commit from the master branch, meaning it has incorporated the numerous bug fixes, graphical/performance improvements, and new features from the vanilla build over the last six months. The changelog also mentions faster shader compilation times, quicker boot times, “performance increases across the board,” and workarounds for AMD and NVIDIA on certain graphics drivers (these bugs has been reported by others, but I personally haven’t come across any issues specific to NVIDIA so far). Unfortunately Vulkan hasn’t been baked into this release, but I would imagine that’s around the corner and going to be in the next version. # ⚓ Godot_Engine_–_Improvements_to_shaders_and_visual_shaders in_Godot_4.0⠀⇛ Hi, I’m Yuri (Chaosus), and I made a number of changes this past 18 months to upgrade the shader language in Godot 4.0 to a better level. There are changes to the editor usability, to the shader language itself, and to visual shaders. # ⚓ Valve_hosting_a_Steamworks_Virtual_Conference_for_the_Steam Deck_on_November_12_|_GamingOnLinux⠀⇛ As we approach launch for the Steam Deck in December, Valve has begun ramping up their info for developers with the announcement of a Steamworks Virtual Conference. # ⚓ Hacking_An_Obsolete_Yet_Modern_Calculator_|_Hackaday⠀⇛ Even before the creation of these graphing calculators, the z80 processor behind them was first produced over four decades ago and was ubiquitous in the computer scene at the time, which also lends to its hackability. There’s plenty to catch up on here, too, from custom TI games that trick the two-tone display into grayscale to Game Boy emulators that can play Zelda since the TI and Game Boy share the same processors. There are also several methods of running native code or otherwise “jailbreaking” these devices to run arbitrary code. # ⚓ The_20_Best_Linux_Gaming_Websites_That_Every_Gamer_Must Know⠀⇛ Gaming on Linux is now a term that we can no more address a very complex task. Moreover, we can say that many developers and Linux enthusiasts are building up more suitable games for Linux and setting up arrangements to play the most popular PC games on Linux systems. To spread the Linux gaming news and guide the gamers with proper instructions, gaming websites for Linux are playing a vital role in the Linux gaming sector. On the web, there are a few Linux gaming websites that are built by actual Linux gaming enthusiasts. # ⚓ Warzone_2100_the_‘Spectre_Update’_is_out_with_game_replays, spectating_and_more_|_GamingOnLinux⠀⇛ The Spectre Update is live now for Warzone 2100, the real-time strategy game originally developed by Pumpkin Studios and published by Eidos Interactive that’s nowadays free and open source. Absolutely great strategy game, I can’t tell you of my joy being able to play this easily on modern systems after originally discovering it on the first PlayStation such a long time ago. The open source community that’s built up around it just keeps on bringing out fantastic enhancements that keep the essence of the game but just make it nicer overall. # ⚓ Graveyard_Keeper_DLC:_Better_Save_Soul_is_out_now_| GamingOnLinux⠀⇛ Published by tinyBuild and developed by Lazy Bear Games, Better Save Soul is the third story DLC for the medieval graveyard building and management game. With an extra 6-12 hours of story-driven gameplay, Better Save Soul introduces you to Euric, a new and slightly sketchy friend with an assortment of gravely important missions to complete, this time centred around the sinful souls of the deceased and how you might improve them before putting them six feet under. # ⚓ The_‘Grand_Tour’_update_for_extreme_sports_game_Descenders is_out_|_GamingOnLinux⠀⇛ Another big free upgrade for the extreme sports biking game Descenders is live with Grand Tour, attending plenty of new goodies for all players. With this new update there’s three whole new bike parks with Llangynog Freeride, Rival Falls, and Island Cakewalk. A new mission system to expand the challenges, each giving a unique objective for you. New rewards were added too with a bunch of new items to unlock. You also get new custom lobby options, so you can really set things up exactly how you want. Quite a big update then overall, nice to see they’re still giving this quality game plenty of love two years after release. o § Desktop Environments/WMs⠀➾ # ⚓ Xfce’s_Apps_Update_for_October_2021:_New_Releases_of Ristretto,_Xfce_Terminal,_Whisker_Menu,_Xfdashboard⠀⇛ The month of October 2021 brought some great application releases for users of the lightweight Xfce desktop environment, starting with the powerful Ristretto image viewer, which has been updated to version 0.12.0, a release that introduces the ability to choose the default scale, support for entering full-screen mode by double clicking on the image, and the ability to keep the scale in memory for each loaded image. o § Distributions⠀➾ # § New Releases⠀➾ # ⚓ antiX_21_Update_Available_to_Download_Based_on_Debian 11⠀⇛ antiX 21 Update Available to Download, antiX 21 is a lightweight, Debian-based distribution. The project’s latest release is based on Debian 11 “Bullseye” and features the SysV init software along with both recent and older kernels for wider hardware support. A list of key packages is available in the project’s release announcement: ” Based on Debian 11 (Bullseye), but without systemd and libsystemd0. eudev instead of udev. Customised 4.9.0-279 kernel with fbcondecor splash. Customised 5.10.57 kernel (x64 full only). LibreOffice 7.0.4-4. Firefox-esr 78.14.0esr-1 on antiX-full.

Your donations help keeping them alive. # § Canonical/Ubuntu Family⠀➾ # ⚓ Linux_Mint_Debian_Edition_(LMDE)_4_ditches_Mozilla Firefox_ESR_web_browser⠀⇛ Linux Mint is based on Ubuntu — that is pretty common knowledge. But did you know there is a different version of the operating system that is instead based on Debian? It’s true! Called “Linux Mint Debian Edition,” or “LMDE” for short, it is far less popular than the “regular” Mint. Then why does it exist? Believe it or not, it exists (partly) to serve as a contingency plan in case Ubuntu ever stops being developed. Today is November 1, and the Linux Mint developers have shared some monthly development news that is largely boring. One small tidbit of information is interesting, however; Linux Mint Debian Edition 4 (code- named “Debbie”) will ditch the Mozilla Firefox ESR web browser. LMDE 4 will instead move users to the normal “rapid release” variant. Speaking of Firefox ESR, Mozilla says that version of the web browser “receives major updates on average every 42 weeks with minor updates such as crash fixes, security fixes and policy updates as needed, but at least every four weeks. In addition to different update cycles, the ESR currently has access to additional policies that are not available on rapid release.” # ⚓ Linux_Mint_Monthly_News_–_October_2021⠀⇛ Following some of the discussions we had here on this blog and your feedback in the comments section, the upcoming versions of Xed and Xreader will feature an option to hide the menubar. When it is hidden the application uses less space and fits in smaller screen resolution. Pressing the Alt key makes the menubar visible momentarily. Xed also gained the ability to switch between opened tabs using Ctrl-Tab and Ctrl-Shift- Tab. The System Reports tool will check systems to ensure they’re merged (i.e. according to usrmerge specs) and warn users when this isn’t the case. In LMDE 4, Firefox 78 ESR will be upgraded to version 94. LMDE will no longer follow the ESR version. It will use the same version of Firefox as Linux Mint. # ⚓ Canonical_Extends_Reach_of_MicroK8s_–_Container Journal⠀⇛ Canonical has updated its lightweight distribution of Kubernetes, known as MicroK8s, to add support for version 1.22 of Kubernetes in addition to making available in beta a version that now runs on IBM Z mainframes. In addition, Canonical has made it simpler to employ Kata containers based on a lightweight hypervisor on MicroK8s via a single command. o § Devices/Embedded⠀➾ # § Mobile Systems/Mobile Applications⠀➾ # ⚓ Android_12L_hands-on:_Early_emulator_experience_ [Video]_–_9to5Google⠀⇛ # ⚓ When_is_Android_12_coming_to_Asus_Zenfones?⠀⇛ # ⚓ Swift_Backup_now_supports_Android_12_and_rootless batch_backups_via_Shizuku⠀⇛ # ⚓ How_To_Enable/Disable_Quick_Settings_Media_Player_In Android_12⠀⇛ # ⚓ The_LG_Wing_finally_starts_receiving_Android_11_– NotebookCheck.net_News⠀⇛ # ⚓ Google_Made_A_Dirt-Cheap_Android_Phone_That_Costs Under_$90⠀⇛ # ⚓ All_you_need_to_know_about_Android_Enterprise Recommended_phones⠀⇛ # ⚓ 5_Best_Android_Phones_–_ExtremeTech⠀⇛ # ⚓ These_are_the_best_Google_apps_for_your_Android._– Bestgamingpro⠀⇛ o § Free, Libre, and Open Source Software⠀➾ # ⚓ Switch_from_Zoom:_How_to_run_your_own_videoconferencing platform⠀⇛ You don’t necessarily need to pay for fully functional conferencing software. Jitsi is a complete free-to-use open-source option that includes end-to-end encryption and integration with Google, Microsoft products and Slack. First appearing under the name SIP communicator in the early 2000s, it’s now run by communications specialist 8×8, which supports the ongoing development of Jitsi alongside its commercial hosted videoconferencing solution. # § Web Browsers⠀➾ # § Mozilla⠀➾ # ⚓ Firefox_94_Is_Now_Available_for_Download, Brings_EGL_on_X11_for_Intel/AMD_Users⠀⇛ The biggest new feature of the Firefox 94 release is the enablement of the EGL (OpenGL) API for handling graphics context management on X11 for Intel/AMD users using recent Mesa graphics stacks. This feature replaces the old GLX implementation and promises to offer a performance boost on Intel/AMD hybrid machines. After upgrading to Firefox 94, Intel/AMD users should notice faster WebGL rendering, more effective rendering, and possibly VA-API video decoding in the near future. # ⚓ This_Week_in_Glean:_Crashes_&_a_buggy_Glean⠀⇛ # ⚓ This_Week_in_Glean:_Crashes_&_a_buggy_Glean_– Data@Mozilla⠀⇛ In September I finally landed work to ship Glean through GeckoView. Contrary to what that post said Fenix did not actually use Glean coming from GeckoView immediately due to another bug that took us another few days to land. Shortly after that was shipped in a Fenix Nightly release we received a crash report (bug 1733757) pointing to code that we haven’t touched in a long time. And yet the change of switching from a standalone Glean library to shipping Glean in GeckoView uncovered a crashing bug, that quickly rose to be the top crasher for Fenix for more than a week. When I picked up that bug after the weekend I was still thinking that this would be just a bug, which we can identify & fix and then get into the next Fenix release. But in data land nothing is ever just a bug. # § FSF⠀➾ # ⚓ FSF:_Free_Software_Awards⠀⇛ The Free Software Foundation has opened nominations for the Free Software Awards. Nominations are open until November 30. # § Development⠀➾ # ⚓ Fortran_newsletter:_November_2021⠀⇛ Welcome to the November 2021 edition of the monthly Fortran newsletter. The newsletter comes out at the beginning of every month and details Fortran news from the previous month. # ⚓ PHPStan_1.0_Released!⠀⇛ Today is a big milestone for PHPStan after 6 years of development. I realized it reached a level of maturity worthy the major version that’s 1.0. Going multiple years [1] without the need for a BC break while delivering improvements in almost streaming fashion with a release every 7 days on average qualifies as being stable enough to deserve it. # ⚓ PHPStan_1.0_Released_As_Leading_PHP_Static_Analyzer_– Phoronix⠀⇛ PHPStan 1.0 was released today as the first stable release for this leading open-source PHP static analysis tool. After being in development more than a half- decade, PHPStan developers felt finally comfortable declaring a 1.0 stable release. Besides feeling confident to mark it v1.0, PHPStan 1.0 does deliver on a new level 9 mode, precise try-catch-finally analysis, generic array function stubs, detecting unused private properties / methods / constants, and much more. # ⚓ Building_a_REST_CRUD_app_with_Golang_Revel_– Citizix⠀⇛ In this guide we are are going to check a simple implementation Revel Framework REST API. In this tutorial we create will be a simple posts CRUD app that will connect to the Postgres Database. Feel free to checkout the repo where the full code is hosted here. # § Perl/Raku⠀➾ # ⚓ Perl_Weekly_Challenge_137:_Long_Year_and Lychrel_Number⠀⇛ # ⚓ Rakudo_Weekly_News:_2021.44_1000+_Rakoons⠀⇛ This week the Raku Community on Reddit makes it to main article on the Rakudo Weekly News. In the roughly two years since the rename, the number of subscribers made it to a 1000! Which does not really reach the number of subscribers on the previous reddit just yet, but on the other hand that had been in use for almost 9 years! And to all new Rakoons: welcome to the Raku Programming Language. # § Rust⠀➾ # ⚓ The_Rust_Programming_Language_Blog:_Announcing Rust_1.56.1⠀⇛ The Rust team has published a new point release of Rust, 1.56.1. Rust is a programming language that is empowering everyone to build reliable and efficient software. * § Leftovers⠀➾ o § Education⠀➾ # ⚓ If_Biden_Won’t_Cancel_Student_Debt,_Why_Should_We_Go_to College?⠀⇛ United States college enrollment is on track to drop by half a million students, according to data released last week by the National Student Clearinghouse Research Center. This rate is on track with 2020’s, when there was a drop of 400,000 students nationally, largely attributed to the coronavirus; if we continue apace, we’ll witness the largest drop-off in U.S. college enrollment in 50 years. But it’s not just because of COVID: This follows a multiyear trend of declining enrollment, due in part to — you guessed it — the cost of college. The numbers are showing that Gen Z is asking a legitimate question: What is the price of a college education really worth in the U.S.? o § Integrity/Availability⠀➾ # § Proprietary⠀➾ # § Security⠀➾ # ⚓ Security_updates_for_Monday⠀⇛ Security updates have been issued by Arch Linux (bind, chromium, freerdp, opera, webkit2gtk, and wpewebkit), Debian (cron, cups, elfutils, ffmpeg, libmspack, libsdl1.2, libsdl2, opencv, and tiff), Fedora (java-latest-openjdk, stb, and thunderbird), Mageia (cairo, cloud-init, docker, ffmpeg, libcaca, php, squid, and webkit2), openSUSE (busybox, chromium, civetweb, containerd, docker, runc, dnsmasq, fetchmail, flatpak, go1.16, krb5, ncurses, python, python-Pygments, squid, strongswan, transfig, virtualbox, wireguard-tools, and xstream), Red Hat (binutils, devtoolset-10-gcc, and flatpak), SUSE (libvirt, opensc, and transfig), and Ubuntu (webkit2gtk). # ⚓ Top_7_Laravel_Security_Practices_Every Developer_Should_Know⠀⇛ Laravel is an open-source development platform that contains a PHP framework, which is one of the most used scripting languages of the 21st century. In spite of its numerous advantages, most Laravel development Agencies are still looking for ways to make the platform and applications made from it more secure. Laravel has a good name for assurance to protect the website and applications. However, if any potential loophole is detected, a capable team within Laravel is always ready to take care of it promptly. Furthermore, there are multiple ways to improve the security of Laravel as no framework can ever claim to have guaranteed security. With the growing popularity and prominence of Laravel, it is crucial to understand the ways to secure the website and applications. Therefore, in this article, we will talk about the Top effective Laravel-based security practices that as a developer you should know to ensure full security! # ⚓ Josh_Bressers:_Episode_295_–_Open_source security_isn’t_free⠀⇛ Josh and Kurt talk about Josh’s electric car and new job. We then talk about the recent UAParser.js malware incident. There have been a lot of calls to do more to secure open source, but nobody seems to have any concrete proposals or suggestions to fund any of these activities. # ⚓ Hiding_Vulnerabilities_in_Source_Code⠀⇛ Really interesting research demonstrating how to hide vulnerabilities in source code by manipulating how Unicode text is displayed. It’s really clever, and not the sort of attack one would normally think about. # ⚓ Trojan_Source:_Invisible_Vulnerabilities⠀⇛ Today we are releasing Trojan Source: Invisible Vulnerabilities, a paper describing cool new tricks for crafting targeted vulnerabilities that are invisible to human code reviewers. Until now, an adversary wanting to smuggle a vulnerability into software could try inserting an unobtrusive bug in an obscure piece of code. Critical open-source projects such as operating systems depend on human review of all new code to detect malicious contributions by volunteers. So how might wicked code evade human eyes? We have discovered ways of manipulating the encoding of source code files so that human viewers and compilers see different logic. One particularly pernicious method uses Unicode directionality override characters to display code as an anagram of its true logic. We’ve verified that this attack works against C, C++, C#, JavaScript, Java, Rust, Go, and Python, and suspect that it will work against most other modern languages. This potentially devastating attack is tracked as CVE-2021-42574, while a related attack that uses homoglyphs – visually similar characters – is tracked as CVE-2021-42694. This work has been under embargo for a 99-day period, giving time for a major coordinated disclosure effort in which many compilers, interpreters, code editors, and repositories have implemented defenses. # ⚓ Microsoft:_Windows_KB5006674,_KB5006670_updates break_printing⠀⇛ Microsoft says Windows customers are experiencing issues with network printing after installing the Windows 11 KB5006674 and Windows 10 KB5006670 updates issued with this month’s Patch Tuesday, on October 12. Users attempting to connect to printers shared on Windows print servers might encounter multiple errors preventing them from printing over the network. # ⚓ Microsoft_warns_of_rise_in_password_sprays targeting_cloud_accounts [Ed: Microsoft_dismissed this_problem_for_a_very_long_time]⠀⇛ # ⚓ New_‘Trojan_Source’_Method_Lets_Attackers_Hide Vulns_in_Source_Code [Ed: It's hardly a new problem, unlike the hype associated with it; phishing tactics do the same]⠀⇛ # ⚓ The_“Trojan_Source”_vulnerability⠀⇛ The latest branded and trademarked vulnerability type is called “Trojan Source”. By playing tricks with Unicode bidirectional support, an attacker can create malicious code that appears to be benign to reviewers. # ⚓ Trick_&_Treat!_Paying_Leets_and_Sweets_for Linux_Kernel_privescs_and_k8s_escapes⠀⇛ Starting today and for the next 3 months (until January 31 2022), we will pay 31,337 USD to security researchers that exploit privilege escalation in our lab environment with a patched vulnerability, and 50,337 USD to those that use a previously unpatched vulnerability, or a new exploit technique. We are constantly investing in the security of the Linux Kernel because much of the internet, and Google—from the devices in our pockets, to the services running on Kubernetes in the cloud—depend on the security of it. We research its vulnerabilities and attacks, as well as study and develop its defenses. # ⚓ Google_Will_Now_Pay_$31,337_To_$50,337_For_New Linux_Kernel_Vulnerabilities_–_Phoronix⠀⇛ Google announced today that now through at least the end of January they will be providing higher payment amounts for security researchers disclosing new vulnerabilities affecting the Linux kernel. For the next three months Google will pay out $31,337 USD for vulnerabilities that can exploit privilege escalation. Or if demonstrating a previously unpatched vulnerability or a new exploit technique, they will pay out $50,337 USD. # ⚓ Bananian_Bananapi_Lamobo_R1_(BCM53125)_–_the ARM_router_that_is_not_a_router_(it_is_a_layer_2 switch_with_only_one_NIC)_–_default_root_password is_pi⠀⇛ it all could have been so well an ARM based router, with HDMI (!) with SATA (!) with enough power, but adding a second interface (every router needs at least LAN (can be layer 2 switch) and WAN (should be physically separate NIC) with an USB-ETHERNET adapter is a low quality (unreliable) option, that one is pretty much against. # § Privacy/Surveillance⠀➾ # ⚓ The_next_privacy_crisis⠀⇛ These are a few of the best- and worst-case scenarios for augmented reality, a technology that some of the world’s biggest tech companies are spending billions to promote as the future of computing. Over the last decade, AR hardware designers have laid the groundwork for a new generation of mass-market products, even as technical hangups still limit its viability. Over the next one, AR threatens to supercharge existing crises of privacy, trust, and consent. But it’s also a chance to deliberately reset how we approach computing. o § Defence/Aggression⠀➾ # ⚓ Bill_de_Blasio_Dodges_Testifying_on_NYPD_Eric_Garner Killing⠀⇛ Instead of accountability for the mayor and police brass, the historic judicial inquiry into the 2014 killing instead focuses on low-level cops. o § Environment⠀➾ # ⚓ It’s_last_call_for_cheap_beer⠀⇛ Input costs have been rising globally, across industries, fueled by a confluence of events: extreme weather that’s destroying global crops, a labor shortage that’s crippling the transport sector, shipping logjams at many of the world’s biggest ports and a worsening energy crisis in Europe and Asia. But the run-up in commodity costs couldn’t have come at a worse time for the global beer sector, which is just starting to recover from the coronavirus pandemic that shuttered bars, restaurants and sporting venues around the globe. # ⚓ Climate_change:_Is_Greta_Thunberg_right_about_UK_carbon emissions?⠀⇛ The UK’s 44% reduction refers to ‘territorial emissions’. These measure what happens within a country’s borders – including things such as heating and powering homes, transport, domestic industry and agriculture. But they exclude emissions from international aviation, shipping and imports. The UK is not unique in producing its figures like this, though. Each year, countries that are signed up to an international agreement called the Kyoto Protocol submit their overall emissions figures to the UN. That reporting is all done on a territorial basis – so they all exclude international aviation, shipping and imports. # ⚓ 10_World_Heritage Forests_are_now_carbon_sources_instead_of carbon_sinks_–_CNN⠀⇛ Human activity and climate change-fueled disasters have turned 10 of the planet’s internationally recognized forests, also known as World Heritage sites, from carbon absorbers into carbon emitters, researchers have found. The report from UNESCO found these sites can absorb approximately 190 million tons of carbon dioxide from the atmosphere each year — roughly half the amount of the United Kingdom’s annual fossil fuel emissions. But in the past 20 years, many of these sites showed an increase in emissions, some even exceeded how much carbon they were removing from the atmosphere. # ⚓ 5_Ways_Climate_Change_Will_Affect_Plants_and_Animals⠀⇛ # § Energy⠀➾ # ⚓ Banks_Tried_to_Kill_[Cryptocurrency]_and_Failed._Now They’re_Embracing_It_(Slowly).⠀⇛ Now the banking industry is racing to catch up. Banks want to compete in this new world and profit from it. Their approach is two- pronged: experimenting with cryptocurrency offerings and lobbying regulators to create rules that work in the banks’ favor. Some are offering cryptocurrency investments to their wealthy clients. Others are weighing trading desks for Bitcoin. JPMorgan even started its own digital currency in 2019. And instead of warning regulators away from cryptocurrencies, banking industry representatives now complain that regulators have not acted quickly enough and that their inaction is costing banks valuable time in their mission to compete. # § Wildlife/Nature⠀➾ # ⚓ Sea_urchins_v_kelp:_the_fight_for_California’s_marine life⠀⇛ Many divers believe the kelp will eventually return. Some scientists are hopeful too, though others see the divers’ efforts as a game of whack-a mole against climate change. But even though their attempts to contain the crisis may prove futile, for the divers, taking any kind of action is comforting in itself. o § Finance⠀➾ # ⚓ Debt_Collective_Program_Cancels_$3.2_Million_in_Carceral Debt⠀⇛ The Debt Collective, which has focused on other forms of debt, is turning its attention to the crushing financial burden on formerly incarcerated people. o § AstroTurf/Lobbying/Politics⠀➾ # ⚓ France:_Can_this_Journalist_Become_President_and_Save France?⠀⇛ France is in an extremely serious situation today. There are more than 700 “no-go zones” (Zones Urbaines Sensibles) ruled by ethnic gangs and radical imams. The police can only intervene in these zones through commando operations. A new kind of disturbance, defined by sociologists as “gratuitous violence” — violence practiced for the pleasure of injuring and killing — has been spreading. Hundreds of assaults take place every day; police reports show that the majority of them are committed by “suburban youths”…. # ⚓ Giant_Chinese-built_Buddha_triggers_popular_backlash_in Laos⠀⇛ The location is also contentious — close to Pha That Luang, the gold-plated Buddhist stupa in the heart of the city. “It would be unacceptable that a large statue was built in the That Muang Marsh SEZ to attract tourism not far from Pha That Luang stupa, a symbol of Lao sovereignty,” said Adisorn Semyaem of Thailand’s Chulalongkorn University, suggesting the anxiety may be as much political as religious. # ⚓ Chinese_developer_provokes_ire_in_Laos_with_100-meter Buddha_statue⠀⇛ This landmark project, built with Chinese loans, has seen Laos sink further into a sea of debt. Reports early this year revealed that Laos’ $20 billion economy carries an estimated $12.6 billion in foreign debt. Of that, China accounts for nearly half of the loans, or some $5.9 billion. China is funding an infrastructure building spree in Laos, ranging from large hydropower projects and special economic zones to the country’s first bullet train. o § Misinformation/Disinformation⠀➾ # ⚓ Hacker_X:_How_Mike_Adams_expanded_his_quack_empire_to politics⠀⇛ Over the years, I’ve written a lot about Mike Adams and his medical misinformation website Natural News. Regular readers know that Mike Adams has long been one of the most prolific promoters of medical pseudoscience, misinformation, and conspiracy theories dating back nearly two decades. Over the last couple of weeks, Adams, who only occasionally makes the news, has found himself in the spotlight as a result of a story published last month at Ars Technica by Ax Sharma entitled “Hacker X”—the American who built a pro- Trump fake news empire—unmasks himself. Basically, it’s the story of “Hacker X,” whose real name is Robert Willis, coming forward to describe how he had become the mastermind of one of the biggest fake news systems in the world but had decided to “come clean” and describe how he had used his skills to promote all manner of conspiracy theories and build a pro-Trump network of websites and social media. # ⚓ Fox_News_Is_Now_Warning_Viewers_That_Biden_Could_Send_Them to_Guantanamo_Bay_Over_School_Board_Protests⠀⇛ So to recap: The situation went from schools trying to protect the health of their students and faculty by requiring masks, to parents threatening the lives of school officials over these mandates, to it getting so bad that the National School Boards Association described the threats as “domestic terrorism” in a letter to Biden, to a fringe Republican like Brnovich equating “terrorism” to “Guantanamo Bay,” to Fox News inviting him on the air, to countless of Americans now believing the Biden administration is going to send parents to an island to be tortured because they said something at a school board meeting. o § Censorship/Free Speech⠀➾ # ⚓ Social_media_vs._the_world⠀⇛ We tend to talk about moderation politics as something that happens between platforms and users (i.e., who gets banned and why), but the Trump debacle shows there’s another side. Like all companies, social platforms have to worry about the politics of the countries they operate in. If companies end up on the wrong side of those politics, they could face regulatory blowback or get ejected from the country entirely. But moderation is politically toxic: it never makes friends, only enemies, even as it profoundly influences the political conversation. Increasingly, platforms are arranging their moderation systems to minimize that political fallout above all else. The problem is much bigger than just Twitter and Trump. In India, Facebook has spent the last seven years in an increasingly fraught relationship with Prime Minister Narendra Modi, cultivating close ties with the country’s leader while violence against India’s Muslim minority continued to escalate. In Myanmar, a February coup forced Facebook to welcome groups it had previously counted as terrorists and suppress groups that mounted military opposition to the new regime. # ⚓ The_GOP_is_the_real_threat_to_free_speech_—_and_it’s getting_worse⠀⇛ To make the situation even more troubling, the right is increasingly embracing the view that they should be allowed to use violence to silence political opponents. Many red states have basically legalized the use of cars as weapons for conservatives who wish to violently attack protesters, especially Black Lives Matter protesters. Laws allowing people to run over protesters — so long as they pretend, in the aftermath, to be afraid — have resulted, according to the Boston Globe, in “scores of people hit, dozens of injuries, at least three deaths, but precious little justice, much less sympathy, for the demonstrators injured, killed, or just plain terrified.” # ⚓ Meet_the_Nicaraguans_Facebook_falsely_branded_bots_and censored_days_before_elections⠀⇛ Facebook, Instagram, and Twitter suspended hundreds of influential pro-Sandinista journalists and activists days before Nicaragua’s November 7 elections, falsely claiming they were government trolls. The Grayzone interviewed them to reveal the truth. # ⚓ Prime_suspect,_accomplice_confess_to_instigating_communal violence_against_Hindus_in_Bangladesh⠀⇛ Shaikat Mandal confessed before a magistrate that it was his Facebook post that led to the violence in Rangpur, during Durga Puja festivities in the country. # ⚓ Internet_must_always_remain_open,_safe;_rules-based accountability_important:_MoS_IT⠀⇛ Accountability and openess are important attributes of cyberspace, he said, adding that in India, the biggest stakeholders of [Internet] are millions of Indians who are using it. The cyberspace “cannot be, should not and will not be” a space where laws do not reach, he asserted. On the requirement for messaging platforms to trace the originator of messages where needed and privacy-related concerns that followed, the minister explained that government’s view on first originator is that when a criminality occurs online, the source of criminality needs to be traced, backed by a legal valid order. # ⚓ Cambodian_court_sentences_autistic_teenager_for_Telegram posts⠀⇛ A Cambodian court sentenced an autistic teenager to eight months in prison on Monday, with part of the term suspended, for sending Telegram messages that were deemed insulting to the government, his mother said. The son of an opposition figure, 16-year-old Kak Sovann Chhay was arrested in late June after posting messages on a private Telegram group, and has been detained for more than four months. o § Freedom of Information/Freedom of the Press⠀➾ # ⚓ Press_freedom_advocate:_Unclear_how_recent_US_kidnapping allegations_will_impact_Assange_case⠀⇛ Speaking on Hill TV’s “Rising,” Higgins said there are “some things” that should be considered as the U.S. seeks Assange’s extradition, but it’s “hard to say” if the report would have an impact. # ⚓ Learning_to_Live_With_Mark_Zuckerberg⠀⇛ The message of this short list was clear: Silicon Valley doesn’t really need East Coast media anymore. It has been more than half a decade since coverage of the tech industry, once known for its boosterism, turned adversarial, with Facebook often at the center of the story. As the battle between tech companies and the news media continues, Mr. Zuckerberg appears to be acting on the view, increasingly common in his circle, that journalists are just another hostile interest. As the opposing sides were digging into their trenches, I thought it would be interesting to talk with Jessica Lessin, a journalist and media executive who often finds herself in an awkward spot somewhere between the battle lines, and who also has an unusually charitable view into both camps. She is the founder and editor of The Information, which started in 2013 as the Silicon Valley’s savvy and nimble answer to The Wall Street Journal, where she had been a star reporter. # ⚓ Mexican_Journalist_Dies_from_Wounds;_2nd_Slain_in_Week⠀⇛ Prosecutors in Acapulco said Friday that Cardoso, who worked for a news portal, had been found sitting on a city street with gunshot wounds and was taken to a hospital. According to the National Union of Press Editors and information from the family relayed by CPJ, Cardoso had been taken from his home earlier Friday by armed men. o § Civil Rights/Policing⠀➾ # ⚓ Ballot_question_asks_Minneapolis_voters_to_consider replacing_police_department⠀⇛ A ballot measure is asking voters if the city should amend its charter to replace the police department with the Department of Public Safety, which would take a “comprehensive public health approach.” The new department could include police officers, but there wouldn’t be a required minimum number to employ. The MPD had 588 officers as of mid-October and was authorized for up to 888, according to The Associated Press. # ⚓ The_high_cost_of_innocence_when_police_seize_cash⠀⇛ All the government must do to win is link assets to wrongdoing, essentially putting inanimate objects on trial rather than humans. The law enforcement maneuver forces property owners into civil court, rather than criminal court, where they have no right to counsel and fewer protections against weak allegations. o § Monopolies⠀➾ # ⚓ How_Proposed_Legislation_Would_Break_Digital_Services:_the Prime_Example_–_Disruptive_Competition_Project⠀⇛ As digital services continue to be a legislative target, some bills being considered in Congress stand to cause permanent harm to widely used services. Two weeks ago, Senators Klobuchar, Grassley, and other cosponsors introduced S. 2992, the “American Innovation and Choice Online Act” (AICOA). This bill is the companion to Rep. Cicilline’s similarly named House bill, H.R. 3816, the “American Choice and Innovation Online Act,” (ACIOA), introduced earlier this summer. While the Senate version contains minor variations, both bills would have similar deleterious effects on the U.S. economy and consumers in general. Both target leading tech companies with onerous regulations, and would have serious consequences for consumers. One consequence would be the dissolution of Amazon Prime as it is currently known. This post examines why that would be the case. AICOA and ACIOA would target three key activities that enable Amazon Prime to be such an attractive and useful service for consumers: (1) self preferencing; (2) conditioning preferential status on the purchase of another service; and (3) curating recommendations for Amazon customers. According to the Senate proposal, each violation would result in a fine up to 15% of total revenue during the pendency of the violation (more than double Amazon’s net profit margin) and companies would be precluded from raising traditional pro- competitive or pro-consumer affirmative defenses. What this means in the case of Prime is that despite a wealth of evidence that consumers get great value out of free two-day shipping bundled with other services, none of that evidence is relevant to whether regulators impose penalties. # § Patents⠀➾ # ⚓ EPO_Extends_Xarelto’s_(Rivaroxaban)_Patent_Expiration Until_Jan._2026 [Ed: EPO is evergreening monopolies for the company behind Monsanto]⠀⇛ On Friday, German-based pharmaceutical company Bayer said the European Patent Office (EPO) announced the extension of the company’s patent expiration of the best- selling stroke prevention pill Xarelto (rivaroxaban), according to Reuters. The EPO, which is a legislative body of the European Union, extended the patent’s expiry date by almost two years. # ⚓ How_IV’s_new_auto_patent_offensive_differs_from_past forays_into_the_space [Ed: Microsoft_patent_trolls still at it]⠀⇛ Suits against GM, Toyota and Honda are not the NPE’s first run-in with automakers, but this campaign looks different because of the technologies involved # ⚓ New_referral_to_the_EBoA:_post-filed_experimental evidence_and_plausibility [Ed: Notice how Managing IP, a failing publisher, is now taking payments from litigation firms (Maiwald in this case) in exchange for publishing their marketing/lobbying pieces as though these were news reports]⠀⇛ Stefanie Parchmann of Maiwald considers the long-awaited referral to the Enlarged Board of Appeal regarding plausibility # ⚓ EPO_opposition_procedure [Ed: IAM missing the key point that this should be done outside the control of the EPO, which has a financial incentive to broaden the scope of patents]⠀⇛ The EPO allows applicants to seek patent protection in up to 44 countries via a single, centralised patent application process. As part of this streamlined offering the EPO also operates a centralised procedure by which third parties can seek invalidation of patents granted by the EPO. This process is referred to as ‘opposition’. The ability to attack a granted patent centrally with a view to limiting or revoking it in all designated countries simultaneously is extremely efficient. It is therefore no surprise that the opposition system is well used by businesses wanting to manage risk against third-party patents. Any person wishing to object to a patent granted by the EPO has a nine-month window, starting from the publication of the grant of the patent, in which to file an opposition. The costs associated with bringing an opposition are typically an order of magnitude lower than performing a patent challenge before a national court of a single country. As such, EPO oppositions are a very cost-effective method of invalidating patents in Europe. # ⚓ Confirmation_of_referral_to_EPO_Enlarged_Board_of Appeal [Ed: As usual, litigation companies are failing to note that these_boards_are_profoundly_compromised and_lack_independence, even by their very own admission]⠀⇛ In our previous article, we reported that the EPO’s Boards of Appeal were expected to request clarification from the Enlarged Board of Appeal on the important issue of whether post-filed data may continue to be used as evidence of an inventive step which is already ‘plausible’ from the application as originally filed. # § Software Patents⠀➾ # ⚓ Software_patent_eligibility_practice_at_the_EPO [Ed: EPO-bribed publisher, IAM, still promoting the illegal_agenda_of_software_patents via firms that profit from patent litigation; journalism is dead and replaced by marketing and lobbying]⠀⇛ In common with many patent offices around the world, some inventions that are implemented in software may be patented before the EPO. In this chapter, we explore software patentability covering why only some software inventions are patentable before the EPO, the requirements for an invention to be patentable and how patent practice before the EPO with respect to software inventions may evolve in the future. # ⚓ Biden_USPTO_pick_faces_tough_confirmation; Nokia_licensing’s_strong_Q3;_IV_goes_on_auto attack;_US_damages_surge;_Secure_strong_AI patents_at_the_EPO;_plus_much_more [Ed: EPO and litigation propaganda rag paints software patents as "Hey Hi" and reveals that Microsoft's patent troll (IV) is still attacking everybody in the world]⠀⇛ # ⚓ Drafting_AI_patent_applications_for_success_at the_EPO_–_drafting_the_full_specification [Ed: The new strategy of patent extremists is to get abstract patents by misusing buzzwords like "Hey Hi"]⠀⇛ In this co-published article, Haseltine Lake Kempner’s Kimberley Bayliss takes a practical look at drafting the specifications of different types of machine learning inventions in view of the EPO’s patent eligibility requirements As discussed in our earlier article, there are, broadly speaking, three types of machine learning (ML) inventions: applied-AI, core-AI and hardware inventions. In this article we look at drafting considerations for each in turn. # § Copyrights⠀➾ # ⚓ Team-Xecuter’s_Gary_Bowser_Pleads_Guilty_to_Criminal Charges⠀⇛ Last year the feds indicted three alleged members of the hacking group Team-Xecuter, which marketed and sold various Nintendo hacks. One of the defendants, Canadian Gary Bowser, initially denied the allegations but has since changed his mind. In a plea agreement, Bowser admits his role in the conspiracy. In addition, Bowser also agrees to pay Nintendo $4.5 million in restitution. # ⚓ Manga_Publisher_Wants_to_Sue_Huge_Piracy_Network, Needs_Google’s_Help⠀⇛ Tokyo-based manga publisher Shueisha has filed an application at a court in the US seeking help from Google and Hurricane Electric to identify alleged copyright infringers. Central to the case is Mangabank, a massive manga indexing platform servicing around 80 million visits per month. ╘══════════════════════════════════════════════════════════════════════════════╛ ¶ Lines in total: 11881 ➮ Generation completed at 02:41, i.e. 93 seconds to (re)generate ⟲
