It explains how a project works — a project that does not yet have a name (just generic “geminiproxy” or gemini-proxy.pl). It does not yet go into the technical details and any finer bits, as it’s just a high-level, over-encompassing introduction to what we try to achieve, why it is important (privacy, self-determination etc.) as it is still work in progress and work which we shall revisit later. The code is in Git already (so far there have been bug fixes aplenty), so technically it is publicly available. “The code is in Git already (so far there have been bug fixes aplenty), so technically it is publicly available.”As it stands, at the moment the site has two HTTP and HTTPS (both are fully supported) access points. One is powered by Gemini (static) and another by a database (dynamic). For the former, direct access over gemini:// is possible and very much encouraged. The “master copy”, however, is the latter, as it contains all the images, videos etc. We’ll carry on tinkering for a while and then make follow-up videos/texts with more concrete examples and use cases.

YOU ARE HERE ☞ A Legal No-Man’s Land “Of course, one consequence of the ability of the EPO’s management to act with impunity is that there will never be any access to TRUE justice for those whose human rights have been violated.” –Anonymous,_a_few_days_ago 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇Staff of international organisations like the EPO⦈ Staff of international organisations like the EPO inhabit a legal no-man’s land. Summary: The EPO‘s immunity has been exploited by Benoît_Battistelli and António_Campinos, albeit not without much help from the EPO’s Administrative Council As a general rule, EPO Administrative Council delegates who become implicated in serious “irregularities” in their home countries can expect to face consequences of some kind – even if the “sanction” may ultimately be nothing worse than a small fine or being forced into early retirement. “For all practical intents and purposes, international organisations conduct their affairs in a legal no-man’s land where there are a number of factors tending to facilitate and even encourage maladministration and abuse of power.”This is because when operating on their home pitches these officials must comply with the codes of conduct governing the activities of national civil servants and, in this regard, they are subject to a certain degree of public scrutiny. But – most important of all – in their day-jobs as national civil servants they do not enjoy the privilege of “immunity”. On the contrary, they are subject to the jurisdiction of national administrative and judicial authorities which operate under the framework of domestic law and are subject to parliamentary oversight and some minimum level of accountability. “The low level of internal and external oversight combine with a remarkable absence of public scrutiny to create an environment in which there is a pervasive lack of transparency and accountability.”However, the rules of the game change significantly different when we shift to the supranational arena in which international organisations like the EPO operate. For all practical intents and purposes, international organisations conduct their affairs in a legal no-man’s land where there are a number of factors tending to facilitate and even encourage maladministration and abuse of power. The low level of internal and external oversight combine with a remarkable absence of public scrutiny to create an environment in which there is a pervasive lack of transparency and accountability. “Question: how many fundamental rights enshrined in the ECHR can the EPO violate without consequence for the individuals responsible?” –Anonymous,_a_few_days_ago This often results in the system being skewed by “perverse incentives” because those who become implicated in serious maladministration or other wrong-doings seldom – if ever – get called to account or suffer any prejudice to their “career”. In the case of the EPO, more often than not, such individuals end up being rewarded for their misdeeds. Indeed, they often manage to land lucrative post- retirement sinecures thanks to the EPO’s notorious_revolving_door and the_pan- European_"good_brother"_crony_network. 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇Christoph Ernst from Germany⦈ Some Council delegates like Christoph Ernst from Germany have managed to land lucrative post-retirement sinecures via the EPO’s notorious revolving door. 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇Martti Enäjärvi and EUIPO⦈ Despite his criminal conviction for credit card fraud in Finland, Martti Enäjärvi enjoyed an impressive post-retirement career as a “Special Advisor” to EUIPO director António Campinos. In the next part we will consider how the rank-and-file staff of international organisations like the EPO are exposed to the abuses of managers and senior executives for whom “immunity” all too often translates into “impunity”. █ “So why do the Member States not only tolerate this situation, but also participate (eg by way of CA/D 2/14) in enabling the abuses of human rights at the EPO? Have they no shame?” –Anonymous,_a_few_days_ago ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿

Europe_Has_a_Severe_Corruption_Crisis⠀✐ Posted in Europe, Fraud, Patents at 9:52 am by Dr. Roy Schestowitz Video_download_link | md5sum a0124575f46bf3da906f214b3726f0d2 EPO as Magnet of Corruption Creative Commons Attribution-No Derivative Works 4.0 http://techrights.org/videos/epo-corruption-complex.webm Summary: Whilst a lot of the so-called ‘media’ or so-called ‘news’ sites which are focused on patent issues (also the press at large) choose to ignore EPO corruption this growing epidemic spreads and is being ‘normalised’, not only in Europe but internationally (it’s a pandemic of crime); this vacuum in reporting and much-needed transparency is the rationale for this series, amongst others Part XXXXII of the ongoing_series was released last night at around midnight, as usual. With a projection of about 50 parts in total we’re already looking at a series as long as a 200-page book and it tells the story of unprecedented corruption in European patent offices; it concerns Europe’s largest ever-patent office, the EPO. “Are we being governed by criminals?”The EPO has had issues for a long time, culminating in the occasional strike or protest. But during the Benoît Battistelli years the level of criminality soared in the management tiers; António_Campinos is more of the same, mostly plundering staff and even pensioners. Set aside the effect/impact on ordinary Europeans and scientists all across the world. The video above goes through the latest part and instead of reading through it I try to interject some of my personal thoughts or my personal interpretation of this dire situation. When Europe’s second-largest institution acts in bad faith and intentionally_breaks_laws it’s already bad. That Europe’s largest institution (EU/EC/EP) lets that happen and even_covers_up_the_abuses is even worse. Are we being governed by criminals? “I feel that many of us,” said an EPO insider quite recently, “not just employees of the EPO, need truth and transparency. I am very optimistic at one thing: the public will be aware of the scandals in the EPO, many of my colleagues have retired with a “big file” containing confidential documents, a kind of insurance against bullying from the Office. At the end, truth will emerge.” █ ䷩ 𝚕𝚒𝚗𝚎 1891 ╒═══════════════════ 𝐃𝐀𝐈𝐋𝐘 𝐋𝐈𝐍𝐊𝐒 ═════════════════════════════════════════════╕ ⠀⌧ █▇▆▅▄▃▂▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁ 02.06.22⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▂▃▄▅▆▇█ ⌧ Gemini_version_available_♊︎ ✐ Links_6/2/2022:_Inkscape_1.1.2_and_GNU_Guile-SDL_0.6.0⠀✐ Posted in News_Roundup at 3:18 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⠀➾ # ⚓ IDC:_tablet_and_Chromebook_shipments_grew_in_2021,_but things_are_slowing_down_–_GSMArena.com_news [Ed: IDC is Microsoft_mouthpiece]⠀⇛ 2020 was a banner year for tablets with record shipments in the fourth quarter. This was driven by the surge of people who work or study at home due to the pandemic. Now with the pandemic easing off, shipments are slowing down as well, according to data from the IDC. 2021 was still positive for manufacturers as total shipments went up 3.2% for the full year, reaching a total of 168.8 million. That’s the most slates shipped since 2016. However, the final quarter of the year made it clear that the demand is past its peak. In Q4 2021 tablet shipments were down to 46 million units, the first decline since the pandemic began. Also, almost all manufacturers in the Top 5 posted negative year-over-year growth (all but Amazon, which is essentially level with a 1.3% rise). o § Applications⠀➾ # ⚓ Inkscape_1.1.2,_1.2_alpha_released,_About_Screen_Contest and_Other_Exciting_News!⠀⇛ You’ll be pleased to hear that we are releasing a bugfix version which solves nearly 60 issues and improves translations for 15 languages! This release includes many crash fixes and resolves issues with a number of broken extensions. Download Inkscape 1.1.2 now for a smoother experience. # ⚓ Best_Whiteboard_Applications_for_Linux_Systems⠀⇛ We will show you a couple of whiteboard applications for Linux systems. I am sure these are going to be super beneficial for you. Read on. o § Instructionals/Technical⠀➾ # ⚓ How_to_Install_Slack_on_Linux:_An_Easy-to-Follow_Guide⠀⇛ This guide will show you how to easily install the Slack application on both Ubuntu and Debian, as well as RedHat-based distributions such as AlmaLinux, Rocky Linux, and Fedora. # ⚓ How_to_Create_a_Network_Proxy_Using_Stream_Processor_Pipy⠀⇛ # ⚓ How_to_Install_ZoneMinder_on_Ubuntu_22.04_|_20.04_LTS⠀⇛ Zoneminder is a free and open-source surveillance camera management software available for Linux only. Here we will learn the steps to install ZoneMinder on Ubuntu 20.04 Focal Fossa or Ubuntu 22.04 Jammy JellyFish. # ⚓ How_to_install_Lightworks_Video_Editor_on_your_Chromebook⠀⇛ As crazy as it may sound, it has been more than four years since we unearthed the container project that would eventually be responsible for bringing Linux to Chromebooks. It has also given us new tools such as Windows on Chrome OS thanks to the efforts of Parallels. When Google first announced Linux on Chromebooks and the ability to leverage the integrated GPUs on Chrome OS devices, my thoughts immediately went to video editing. # ⚓ How_to_install_GNOME_Desktop_Environment_on_Debian_11_| FOSS_Linux⠀⇛ Debian 11 comes with loads of great features for casual and advanced users. Some of these great features that make Debian 11 so attractive are its stability, security, support for many architectures, a great deal of support from the community, and support for multiple Desktop Environments like GNOME, Cinnamon, Xfce, etcetera. It is ideal for servers as well. With that said, there is no denying that GNOME is one of the most versatile desktop environments that Debian supports. It is very stable and has tons of customizability options so that you can tweak it to your liking. But still, if you are over the fence about whether you should try the GNOME desktop environment (DE) or not, you can check out this great article that explains in detail ten reasons why the GNOME DE rocks. o § Games⠀➾ # ⚓ Steam_Deck_already_has_more_than_100_verified_and_playable games [Ed: Thousands of games would work OK, but just haven't been officially verified yet]⠀⇛ Valve officially announced its first portable gaming console, the Steam Deck in July, 2021. The company promised that the console would be able to run AAA titles, mainly games that are already available to be played on PC. The company also recently confirmed that devices would start shipping out to customers by the end of February. Valve also launched a Steam Deck Verified program that aimed at testing already existing and future games on the Steam Deck, to ensure that they are playable. Each individually tested game receives a score at the end, which will help gamers know whether their favorite games are supported by default, or if they’re unspotted for various reasons. # ⚓ Valve_has_over_100_playable_games_for_the_Steam_Deck⠀⇛ Valve has tested over 100 games that will work with the upcoming Steam Deck. From the 106 total games that will work, 60 are verified to the highest compatibility – meaning the controller configuration and glyphs will match, the interface is legible and that performance is good. There are further 41 games that are playable, which means that depending on the game, some tweaking will be needed to make the game work as intended. 5 games were deemed unsupported, but 4 of those are VR games, which naturally won’t work on the Steam Deck. # ⚓ Valve_Just_Made_Steam_Deck’s_Secret_Weapon_Even_Better⠀⇛ Valve’s Steam Deck begins shipping out to early adopters at the end of February. And some of you lucky Deck owners might feel tempted to switch over to Windows for 100% game compatibility. But Valve has an awesome (and proven) secret weapon to keep you on Deck’s default OS. The Arch Linux-based SteamOS 3.0 now has AMD FSR built in. Here’s why that’s a big deal. # ⚓ New_York_Times_outlays_seven-figure_sum_for_1,900_lines_of JavaScript_–_yes,_we_mean_Wordle⠀⇛ Viral online puzzle game Wordle has been acquired by The New York Times Company (NYTCo), publisher of The New York Times. The game requires players to guess a five-letter word within six turns – a task made easier by Wordle offering clues that players have chosen letters used in the word, and whether or not they are in the right position. Gameplay is similar to codebreaking pegboard game Mastermind, but with 26 different “pegs” – and of course the answer has to be an English word. A single puzzle is offered daily. o § Distributions⠀➾ # § New Releases⠀➾ # ⚓ What’s_New_in_elementary_OS_6.1_and_Should_You Switch?⠀⇛ The new elementary OS 6.1, codenamed “Jólnir” comes packed with a bunch of new features and updates. Here’s everything you need to know. elementary OS is a modern-day Linux distro with a slew of innovative features and a gorgeous user interface. It targets users who are coming from either macOS or Windows background. But users of traditional Linux systems will also find elementary OS appealing, thanks to its redefined desktop environment and sleek design language. The developers have recently released elementary OS 6.1, dubbed Jólnir. It’s the first point release in the 6 series and succeeds elementary OS 6, Odin. # § IBM/Red Hat/Fedora⠀➾ # ⚓ Clemson_partners_with_IBM_and_AgStack_to_aid_global food_access [Ed: Openwashing and greenwashing of IBM, sponsored by IBM itself with help from LF, its front group]⠀⇛ # ⚓ For_IBM,_AI_Inference_Is_The_Most_Important_HPC [Ed: Timothy Prickett Morgan really is an IBM-sponsored PR machine; and he's not disclosing the funding source of the puff pieces]⠀⇛ All of the commercial platform creators in the world, since the dawn of time, which arguably started in the enterprise in April 1964 with the advent of the System/360 mainframe, wants the same things. They want to create a flexible, integrated, and useful system where data can be stored and applications run against it or create the starting data, and one that provides the maximum value to customers while at the same time allowing them to extract the maximum value out of customers. # ⚓ IBM_Preconfigures_Power_System_Racks_Running_Oracle Database [Ed: Timothy Prickett Morgan still doing IBM puff pieces without disclosing IBM pays him to do this...]⠀⇛ # ⚓ A_Complete_Rethinking_Of_Server_Virtualization Hypervisors⠀⇛ # § Debian Family⠀➾ # ⚓ Raspberry_Pi_OS_Is_Now_Available_In_Glorious_64-bit_– Review_Geek⠀⇛ After a year of beta testing, a stable version of the 64-bit version of Raspberry Pi OS is finally available. This long-awaited operating system increases software compatibility for closed-sourced applications, which are often exclusive to ARM64. Additionally, 64-bit Pi OS should improve benchmark performance (not necessarily real-world performance) thanks to its improved instruction set. # ⚓ Raspberry_Pi_OS_now_available_in_64-bit,_improving app_compatibility⠀⇛ The Raspberry Pi series of single-board computers has been a runaway success over the years, thanks to its fantastic versatility and low cost. From powering DIY electronics projects to functioning as cheap PCs for learning programming, the Raspberry Pi series can do it all, and now another significant upgrade has arrived: a 64-bit version of the default operating system. There are a few different operating systems available for Pi boards, including a few attempts at Android, but the default operating system that most people go with is Raspberry Pi OS. Previously known as Raspbian, it’s a Debian-based Linux desktop specifically built for the Pi family. Even though some newer Pi computers have 64-bit ARM CPUs, Raspberry Pi OS has remained only 32-bit, except for beta builds. Raspberry Pi said in a blog post (via Ars Technica), “we have continued to build our Raspberry Pi OS releases on the 32-bit Raspbian platform, aiming to maximise compatibility between devices and to avoid customer confusion. […] But we’ve come to realise that there are reasons to choose a 64-bit operating system over a 32-bit one. Compatibility is a key concern: many closed- source applications are only available for arm64, and open-source ones aren’t fully optimised for the armhf port. Beyond that there are some performance benefits intrinsic to the A64 instruction set: today, these are most visible in benchmarks, but the assumption is that these will feed through into real-world application performance in the future.” # ⚓ Raspberry_Pi:_New_‘glorious’_64-bit_operating_system is_available_to_install_|_ZDNet⠀⇛ “Over the past year, we’ve been trialling a beta of Raspberry Pi OS in glorious 64-bit. Now it’s time to open it up to a wider audience,” said Raspberry Pi’s Gordon Hollingworth. He said application compatibility is a “key concern” behind the decision to choose a 64- bit OS over a 32-bit one. “Many closed-source applications are only available for arm64, and open-source ones aren’t fully optimised for the armhf port,” explains Hollingworth, referring to the Debian/Raspbian armfh ports. He adds that there are some performance benefits “intrinsic” to the A64 Armv8 instruction set. Today, these gains can mostly be seen in benchmarks, but Hollingworth believes they will become real- world application performance enhancements in the future. Another “theoretical concern” was that 32-bit pointers only allow users to address 4GB of memory, which wasn’t optimal given developers could use up to 8GB of RAM on the Pi 4. However, as Hollingworth notes, few use cases today require all 8GB of addressable memory from a single process. o § Devices/Embedded⠀➾ # § Open Hardware/Modding⠀➾ # ⚓ Raspberry_Pi_vs._Arduino:_Which_is_best_for_you?_| Android_Central⠀⇛ So you’ve decided to buy a small single-board computer to use in your great idea. There are plenty to choose from, but the two most popular platforms are Raspberry Pi and Arduino. There are plenty of reasons why they are popular, but the two biggest are price and ease of use. Both are cheap and have a small learning curve, so you can spend time designing the rest of your project instead of learning how to use an SBC (single-board computer). Each has a huge community of helpful users if you get stuck, too. You might be thinking that the two are interchangeable and you can buy whichever you want from Amazon, but that’s not the case at all. While you can do some of the same things with either board, they’re unique and have plenty of differences. The one you need really depends on what you want to do with it. # § Mobile Systems/Mobile Applications⠀➾ # ⚓ Test_15_different_PinePhone_operating_systems_with Megi’s_latest_multi-distro_demo_image_–_Liliputing⠀⇛ Trying out different operating systems on the PinePhone is as simple as flashing a bootable disk image to a microSD card, inserting it in the phone, and powering it on and the instructions for installing an OS to built-in storage are almost as simple. Not sure which operating system you want to install though? That’s where a tool like Megi’s multi-distro demo image can come in handy. Instead of flashing a single operating system to a microSD card, this image lets you flash a whole bunch and then choose which one you want to run when you boot your phone. The latest version was released a few days ago, and it contains 15 different operating systems including Arch, Fedora, Mobian, Sailfish, Ubuntu Touch and several different versions of postmarketOS and Manjaro with different user interfaces. o § Free, Libre, and Open Source Software⠀➾ # ⚓ TriggerMesh,_Case_Study_in_Open_Sourcing_Enterprise Software [Ed: "TriggerMesh is a sponsor of The New Stack."

Hive was originally built as a distributed SQL store for Hadoop, but in many cases, companies continue to use Hive as a metastore, even though they have stopped using it as a data warehouse. # § Web Browsers⠀➾ # ⚓ The_inside_story_of_the_browser_wars,_told_by_a veteran_|_TechRadar⠀⇛ The story of Brendan Eich is in many ways the story of the evolution of the internet and the technologies we use to access it. It is also a story of battles won, lost and soon to play out. Eich is best known as the creator of programming language JavaScript, which he developed over a sleepless period of ten days in 1995. At the time, he was working for Netscape, whose web browser dominated the market before Internet Explorer spoiled the party. Recognizing that Netscape had lost its way, Eich spun out another project he had been working on, leading to the formation of the Mozilla Foundation. The organization went on to pioneer the concept of browser extensions with Firefox, which quickly became a household name, before it was crushed under the weight of Google Chrome. # § FSF⠀➾ # § GNU Projects⠀➾ # ⚓ GNU_Guile-SDL_0.6.0_available⠀⇛ release notes: Lots of love this time. Shout out to all technical writers! Please see also the (currently wip, it may have finished by the time you read this) "Hooray!" series: . README excerpt: Guile-SDL is a set of modules that provide bindings for various Simple DirectMedia Layer (http:// www.libsdl.org) libraries. Most of the SDL functions are wrapped, with the exception of a few functions that are too C-centric. The SDL threads, audio and network functions are not included. However, there are (optionally configured) bindings for SDL_mixer and SDL_ttf. Also included is SDL_gfx 2.0.26 (by Andreas Schiffler) source code (ZLIB license) and bindings for it. This is alpha code (pre 1.0 release), tested with various, but not all, versions of Guile and SDL. It may have bugs, and the interfaces may change from version to version. NEWS for 0.6.0 (2022-02-05): - bugfix: avoid range error in image filter procedures Procedures ‘imfi-add-c’ and ‘imfi- sub-c’ used to convert 3rd arg ‘c’ (constant) from Scheme to C using a signed integer function that would signal range error for large values. This is now fixed to use an unsigned integer function to do the job. - intermittent crash fix reverted The fix in Guile-SDL 0.5.3 (2021- 12-11) was not The Right Thing. It has been reverted and a better solution put in place. We now initialize the ‘event-thread’ subsystem in test/cursor.scm. AHA moment: . - embedded SDL_gfx upgraded to version 2.0.26 This brings bugfixes and MMX support for x86_64 (amd64), primarily. Now, "cd test && make check TESTS=gfx.scm" really flies! NB: The license for SDL_gfx is now the zlib license. See src/SDL_gfx/LICENSE in the distribution for the new text. - ‘(sdl gfx) fps-manager-delay!’ can have meaningful rv The embedded SDL_gfx is currently at version 2.0.26, but the previous version was 2.0.22, and its function that underlies ‘fps-manager-delay!’ did not have a meaningful return value. Previously, if you configured w/ ‘- -disable-embedded-gfx’ and built w/ SDL_gfx 2.0.24 or later (that DOES have a meaningful rv), such ignorance was foisted upon you. Now, you are free to fully enjoy that sweet rv. :-D - changes to to ‘(sdl gfx) blit-rgba’ - accepts ‘#f’ for 2nd, 4th arg The 2nd and 4th args to ‘blit- rgba’ indicate the source and destination rectangles, respectively. Previously, they were required to be fully specified. Now, you can use ‘#f’ there to indicate the entire (source/ destination) surface. - return value more informative Previously, ‘blit-rgba’ returned ‘#f’ if there were problems and ‘#t’ if not. However, "no problem" was narrowly interpreted and missed a certain common case - - upshot is that it incorrectly returned ‘#f’ even in that case. Now, if there were no problems, it returns an integer: 1 if a blit was performed, 0 otherwise. (If there were problems, it returns ‘#f’ as before -- use ‘get-error’ to get more info.) - new proc: ‘(sdl misc-utils) exact- floor’ Actually, this is an old proc that was misguidedly deleted in 2011 to make room for ‘exact- truncate’. Both are useful in their own right, it is now evident. Live and learn. - new proc: ‘(sdl sdl) must-lock?’ This wraps the convenience C macro ‘SDL_MUSTLOCK’. Useful (in conjunction w/ ‘lock-surface’ and ‘unlock-surface’) for avoiding segfaults when examining pixel data from RLE-enabled surfaces. - new proc: ‘(sdl gfx) multiply- pixel-alpha!’ This multiples the alpha channel in a 32-bit surface by FACTOR (actually, FACTOR/256). The underlying function has been available in SDL_gfx since version 2.0.21, so this is a bit of a late bloomer. Still, more alpha blending for everyone! - new proc: ‘(sdl gfx) fps-manager- count’ This returns the frame count (i.e., how many times ‘fps-manager-delay!’ was called) for an FPS manager. Another late bloomer (again, since SDL_gfx 2.0.21). - documentation improvements - external representations described The manual now includes a description of the external representation of these object types: Pixel Format Rectangle Color Surface Joystick CDROM Drive FPS Manager Types with a standard (non- custom, Guile-generated) external representation are not documented. By the way, the Surface external representation now also includes "L" to indicate that the surface is locked. - image filtering procedures general behavior documented The manual now sports three paragraphs describing commonalities of the ‘imfi-*’ procedures, as well as the special processing done by ‘imfi-add-c’, ‘imfi-sub- c’, ‘imfi-lshr’, ‘imfi-lshl’. - say "byte", not "nybble" The documentation for ‘surface- pixels’ was simply wrong (but it sounded groovy for a while to Some Fool, probably). - bootstrap/maintenance tools upgraded: Guile-BAUX 20211208.0839.a5245e7 GNU gnulib 2022-01-27 07:00:41 as before: GNU Libtool 2.4.6 GNU Autoconf 2.71 GNU Automake 1.16.5 GNU Texinfo 6.8 tarballs and detached signatures: https://ftpmirror.gnu.org/guile-sdl/ guile-sdl-0.6.0.tar.lz https://ftpmirror.gnu.org/guile-sdl/ guile-sdl-0.6.0.tar.lz.sig source code: https://git.savannah.gnu.org/cgit/ guile-sdl.git/?h=p homepage: https://www.gnu.org/software/guile-sdl/ * § Leftovers⠀➾ o ⚓ China_reveals_draft_deepfake_regulations_that_restrict_use_•_The Register⠀⇛ The Chinese government has unveiled a draft law clamping down on deepfakes – the practice of using AI to adapt existing digital content into realistic simulations of humans. The draft emerged last Friday from the Cyberspace Administration of China and frames the need for regulation in the context of the government’s desire to ensure the internet is a tool for good and not the wretched hive of scum and villainy it has often become. The explanatory memorandum for the policy suggests criminals and fraudsters will be attracted to using digitally created voice, video, chatbots, or manipulation of faces or gestures. The draft therefore rules out the use of such fakes for any application that could disrupt social order, infringe individuals’ rights, deliver fake news, or depict sexual activity. It also proposes requiring a grant of permission for use of what China calls “deep synthesis” before it can be employed for legitimate uses. o § Science⠀➾ # ⚓ Streptococcal_pyrogenic_exotoxin_B_cleaves_GSDMA_and triggers_pyroptosis_|_Nature⠀⇛ Gasdermins, a family of five pore-forming proteins (GSDMA–GSDME) in humans expressed predominantly in the skin, mucosa and immune sentinel cells, are key executioners of inflammatory cell death (pyroptosis), which recruits immune cells to infection sites and promotes protective immunity. o § Hardware⠀➾ # ⚓ Chip_shortage_has_NXP_in_driver’s_seat_•_The_Register⠀⇛ Chip shortages are so bad that customers are willing to sign multiyear non-cancellable, non- returnable (NCNR) contracts to secure supplies, according to semiconductor supplier NXP. Buyers want to have clear visibility on their component orders, and “want to have it longer,” said NXP CEO Kurt Sievers during an earnings call this week, adding customers “would love to have NCNRs for two years out.” This is a symptom of the across-the-board electronics shortages in sectors including industrial and automotive, which have “very sticky products, very long life cycles, so it fits the nature of those industries,” Sievers said. NXP isn’t alone in this. Analyst house IC Insights reported NCNR policies are increasingly becoming popular for chip manufacturers for those worried about losing supplies. o § Health/Nutrition/Agriculture⠀➾ # ⚓ Academic_performance_and_attitudes_of_dental_students impacted_by_COVID-19⠀⇛ Previous studies only focused on attitudes and behaviors of US dental students without examining direct effects of the COVID-19 pandemic on academic performance. This study examined effects of COVID- 19 pandemic on dental students’ academic performance, self-reported attitudes, behavior, and service utilization. We hypothesized that the pandemic provided more beneficial learning environments. # ⚓ Top_strategies_and_tools_to_prevent_employee_isolation⠀⇛ Feelings of isolation and loneliness are growing as employees continue to work from home. [...] Loneliness directly impacts physical health and can lead to issues such as high blood pressure and obesity, which can in turn increase an organization’s overall healthcare costs, said Darcy Gruttadaro, director of the American Psychiatric Association Foundation’s Center for Workplace Mental Health, located in Washington, D.C. The organization educates employers about how to support their workers’ well-being. # ⚓ Work_From_Home_Or_Anywhere:_Top_30_Companies_For_Remote Jobs_In_2022⠀⇛ Even before the pandemic uprooted everything in 2020, more and more people had been ditching the 9- 5 to work remotely and travel the world. But in 2020, only 5% of remote jobs could be done from anywhere. Fast forward to 2022 and it’s a whole new world, where remote working is not only a dream, it’s a reality. # ⚓ HDD_Centrifuge_Puts_COVID-19_Testing_Lab_In_A_Backpack_| Hackaday⠀⇛ Throughout this two-year global COVID-19 nightmare, one thing that has been sorely lacking is access to testing. “Flu-like symptoms” covers a lot of ground, and knowing if a sore throat is just a sore throat or something more is important enough that we’ve collectively plowed billions into testing. Unfortunately, the testing infrastructure remains unevenly distributed, which is a problem this backpack SARS-CoV-2 testing lab aims to address. The portable lab, developed by [E. Emily Lin] and colleagues at the Queen Mary University of London, uses a technique called LAMP, for loop-mediated isothermal amplification. LAMP probably deserves an article of its own to explain the process, but suffice it to say that like PCR, LAMP amplifies nucleic acid sequences, but does so without the need for expensive thermal cycling equipment. The kit contains a microcentrifuge that’s fashioned from an e-waste hard drive, a 3D printed rotor, and an Arduino to drive the motor and control the speed. The centrifuge is designed to run on any 12 VDC source, meaning the lab can be powered by a car battery or solar panel if necessary. Readout relies on the trusty Mark I eyeball and a pH-indicating buffer that changes color depending on how much SARS-CoV-2 virus was in the sample. o § Integrity/Availability⠀➾ # § Proprietary⠀➾ # § Security⠀➾ # ⚓ Open-source_Kubernetes_tool_Argo_CD_has_high- severity_flaw_•_The_Register⠀⇛ A zero-day vulnerability in open-source Kubernetes development tool Argo lets malicious people steal passwords from git-crypt and other sensitive information by simply uploading a crafted Helm chart. Charts are the actual packaging format of ubiquitous tool-for-managing- Kubernetes applications Helm. The vuln, tracked as CVE-2022-24438, exists in Argo CD, a widely used open- source continuous delivery tool for Kubernetes. Patched versions available from the project’s maintainers are 2.19, 2.2.4 and 2.3.0. “It is possible to craft special Helm chart packages containing value files that are actually symbolic links, pointing to arbitrary files outside the repository’s root directory,” said a member of the Argo project in a security advisory about the flaw. # ⚓ 12_CISO_resolutions_for_2022⠀⇛ It’s still early days, but if this year is anything like years past, it’s safe to say CISOs will have a lot to contend with, from a continuing labor shortage to the increasing sophistication of cyberattacks to an ongoing threat from nation-state actors. # ⚓ Critical_Samba_Remote_Code_Execution_Flaw Fixed⠀⇛ Samba has patched a vulnerability that could enable remote, unauthenticated attackers to execute arbitrary code as root on impacted installations. Samba is an interoperability software suite that implements the Server Message Block (SMB) networking protocol, which provides file and print services. It allows network administrators to configure and set up equipment as a domain controller (DC) or domain member, and to communicate with Windows-based clients. Samba runs on many Unix or Unix-like systems like Linux, as well as macOS and other operating systems that use the SMB protocol. # ⚓ EU_launches_bug_bounty_programs_for_five_open source_solutions⠀⇛ This time around, the list of software that should be probed for weaknesses includes: LibreOffice – a free office suite Mastodon – free and open-source software for running self-hosted social networking services Odoo – a suite of business management software Cryptpad – a browser-based encrypted open-source collaboration platform that allows people to work together online on documents, spreadsheets, and other types of documents LEOS is a software tool for drafting and editing legislation, which is used by European Commission, Parliament, Council and several member states # ⚓ Crypto_outfit_Qubit_appeals_to_the_honour_of thieves_who_lifted_$80M_of_its_digi-dollars⠀⇛ Another week, another crypto upstart admitting its lax security has been exploited and parties unknown have made off with millions. But this time there’s a twist: the crypto upstart has appealed for the return of its assets by appealing to the thieves’ consciences. The crypto concern is Qubit Finance – an outfit that offers decentralized lending and borrowing and operates under the motto “Lend to ascend – Borrow for tomorrow.” # ⚓ Targeted_ransomware_takes_aim_at_QNAP_NAS drives,_warns_vendor:_Get_your_updates_done pronto⠀⇛ QNAP has urged NAS users to act “immediately” to install its latest updates and enable security protections after warning that product-specific ransomware called Deadbolt is targeting users’ boxen. “DeadBolt has been widely targeting all NAS exposed to the internet without any protection and encrypting users’ data for Bitcoin ransom,” warned the Taiwanese company in a statement late yesterday. # ⚓ Alpha-Omega_Project_takes_a_human-centered approach_to_open-source_software_security_|_CSO Online⠀⇛ The Log4j vulnerability crisis that erupted in late-2021 heightened the security world’s awareness of supply chain risks in free and universally deployed open-source software. Following an intense holiday season push by admins and cybersecurity professionals to track and remediate the Log4j flaw, the White House held a meeting of industry leaders to discuss improving open source software security. # ⚓ SnapFuzz:_New_fuzzing_tool_speeds_up_testing_of network_applications_|_The_Daily_Swig⠀⇛ An open source fuzzing tool developed by researchers at the Software Reliability Group of Imperial College London aims to solve some of the thorny problems of testing network applications. SnapFuzz uses a series of techniques to speed up the testing of network protocols and overcome the timin constraints and other limitations that make it difficult to fuzz networking applications. While SnapFuzz is still in its early stages, it shows promising results and its developers hope it will soon become a mainstay in the toolbox for testing networking applications. # ⚓ The_Apache_Log4j_team_talks_about_the_Log4Shell patching_process_–_The_Record_by_Recorded Future⠀⇛ On December 9, 2021, the internet learned of a major security bug in a little-known Java library named Apache Log4j. This little bug—codenamed Log4Shell—had one of the most significant impacts on the software landscape and triggered one of the most massive and well-coordinated patching drives in the recent history of the internet. For the past month, government agencies, security firms, and IT experts alike have all worked together to audit Java-based applications, find which were vulnerable to Log4Shell attacks, worked with vendors to deliver patches, and then encouraged their customers to apply them as soon as possible. # ⚓ Whistleblower_claims_NSO_offered_‘bags_of_cash’ for_access_to_US_phone_networks⠀⇛ A whistleblower’s allegations about spyware maker NSO Group should be investigated by American prosecutors, US House Rep Ted Lieu (D-CA) has said. The informant claimed senior NSO executives offered “bags of cash” to California-based telecoms security and monitoring outfit Mobileum to assist in its surveillance work, according to the Washington Post on Tuesday. Specifically, it’s alleged NSO wanted to gain, with Mobileum’s help, Signaling System 7-level access to US cellular networks, a position that can be abused to determine a cellphone’s location, redirect and read its incoming text messages, snoop on calls, and more. SS7 is the glue between telecommunications providers, and subverting it opens up a wealth of opportunities for spies and miscreants. Gerry Miller, who spent over six years at Mobileum and rose to veep of network security and client solutions, claimed that in August 2017, when asked how Mobileum would get paid, NSO co-founder Omri Lavie said: “We drop bags of cash at your office.” # ⚓ A_tale_of_command_line_booby_traps_and_bored engineers_•_The_Register⠀⇛ Take a trip back to when mainframes and terminals were all the rage and The Cloud was the smoke produced by the mainframe when a washing-machine-sized disk was about to let go. Welcome to another Who, Me? confession. Today’s plea for forgiveness comes from a reader Regomised as “Doug” and is a warning to careless administrators. “Back in the days when terminals were still fairly common,” said Doug, “the company I worked for provided ‘local’ data based on the result of a search run on the client’s main dataset held on their server.” “We could telnet from these terminals to our box – and frequently had to in the early days,” he recalled. The client itself was nationally known in back then and had spanked millions getting this remote site up and running. Things were going swimmingly. Right up until a month after go-live when Doug and a pal were stuck at the client site on a Friday evening. The client’s own engineer had long gone, and Doug was finishing up the last checks to allow a weekly backup to kick off. He ambled up to a darkened terminal near the server room and tapped the return key to bring it to life. The prompt was odd, something he’d not seen before.

But it also gives Apple access to information about me and my behaviour; I become another source in their vast banks of data. So, as Stephanie Hare rightly points out in Technology Is Not Neutral, it’s never just an object. Technology is as much social as scientific, as much economics as engineering. There’s little point in Silicon Valley companies hiring an ethicist to decide a product’s value — its effects go far beyond the shiny thing that comes out of the box. # ⚓ Utopia_P2P:_Internet_with_Privacy_Upgrade –_TheGWW.com⠀⇛ Privacy is the modern internet’s foundational issue. # ⚓ Doubts_over_Facebook’s_ability_to innovate_as_it_sees_first-ever_fall_in_user numbers⠀⇛ # ⚓ UK’s_new_Brexit_Freedom_Bill_promises already-slated_GDPR_reform,_easier_gene editing_rules⠀⇛ The UK government is having a second pass at flogging the benefits of Brexit, as much as they exist, in a new bill that promises to accelerate work on AI and gene editing. The so-called Brexit Freedoms Bill — its actual title will be decided by Parliamentary clerks — will also offer a “more agile way to regulate new digital markets and AI and [create] a more proportionate and less burdensome data rights regime compared to the EU’s General Data Protection Directive.” The bill promises to make it easier to amend or remove “retained EU law” which was left in place following the UK’s departure from the political and trading bloc. o § Defence/Aggression⠀➾ # ⚓ Opinion:_UCLA_must_investigate_holdings_for_ties_to_Uyghur genocide_–_Daily_Bruin⠀⇛ As the Uyghur genocide continues to unfold, our institutions don’t deserve the benefit of the doubt. The Uyghurs are a predominantly Muslim ethnic minority that live in the autonomous region of Xinjiang. The Chinese government, under the semblance of counterterrorism, seeks to deprive Uyghurs of their religious and cultural identities. Many human rights organizations have documented the mass internment, torture and religious persecution of Uyghurs at the hands of the Chinese government. Other allegations include forced labor, sterilization and reeducation – all amounting to the official label of genocide according to the U.S. Department of State. # ⚓ UK_to_splash_another_£1.4bn_on_protecting_non-existent ‘national_interests_in_space’⠀⇛ The UK government is to spend an extra £1.4bn on space defence on top of the £5bn allocated to upgrade the Skynet satellite communication system. The Defence Space Strategy, intended to “bolster our national interests in space,” according to the UK’s Ministry of Defence, was accompanied by a speech from Chief of the Air Staff Sir Mike Wigston in which the usual bogeymen were trotted out. “Russia and China have tested anti-satellite weapons creating debris fields that will linger for decades,” warned Wigston, adding: “Russian satellites continually make close approaches to other satellites, what we call rendezvous and proximity operations, possibly an indication of espionage activity, or possibly rehearsing something much more sinister.” o § Environment⠀➾ # § Energy⠀➾ # ⚓ UK_government_told_to_tighten_purse_strings_or_public will_have_to_foot_the_bill_for_nuclear decommissioning⠀⇛ The UK government is being warned that taxpayers will have to make up a multibillion-pound shortfall to decommission nuclear power stations unless a history of overspending is reversed. French firm EDF Energy runs seven Advanced Gas-cooled Reactor (AGR) stations in the UK, part of eight second-generation reactors set to be decommissioned which provide 16 per cent of the nation’s electricity. The AGR stations are scheduled to stop producing electricity by 2028. Last year the government injected £5.1bn into the Nuclear Liabilities Fund – now valued a £14.8bn – which it set up in 1996 to meet the costs of decommissioning AGR and Pressurised Water Reactor stations. o § Finance⠀➾ # ⚓ No,_Linus_Torvalds_is_not_Bitcoin_Creator_Satoshi_Nakamoto [Ed: Feeding clickbait with more clickbait]⠀⇛ # ⚓ India_to_adopt_digital_rupee_and_slap_a_30_per_cent_tax_on cryptocurrency_income⠀⇛ India’s government has ordered its Reserve Bank to have a digital rupee into circulation by next year, and outlined plans to raise revenue with a 30 per cent income tax on cryptocurrency and non-fungible tokens. The two plans were announced yesterday by finance minister Nirmala Sitharaman as she revealed the nation’s budget for 2022. The crypto tax is the first item listed in a section of the budget memo headed “Revenue Mobilization”. The document [PDF] explains that India wants to tax income from crypto-assets at a 30 per cent flat rate. By comparison, India currently taxes short-term capital gains made by selling shares at 15 per cent. The budget memo also calls for a one per cent tax on sales of cryptographic assets, payable by parties to the transaction, to widen India’s tax base. o § AstroTurf/Lobbying/Politics⠀➾ # ⚓ Gaming_Twitter’s_Trending_Algorithm_To_Make_A_Point_| Hackaday⠀⇛ If you have ever taken to Twitter to gauge the zeitgeist, you’ll have noticed that among the trending hashtags related to major events of the day there are sometimes outliers of minority interest associated with single-issue causes. When a cause with a distasteful pedigree was cited one as proof of widespread public support in a debate in the UK’s House of Lords there were concerns raised that a flaw in the ranking algorithm might be responsible, and it was left to [Mallory Moore] to prove the hypothesis by getting a #ThisIsAnExploit hashtag trending without a groundswell of popular support. o § Censorship/Free Speech⠀➾ # ⚓ The_EARN_IT_Act_is_back_to_attack_Section_230_protections_• The_Register⠀⇛ The EARN IT Act, a legislative bill intended “to encourage the tech industry to take online child sexual exploitation seriously” has been revived in the US Senate after it died in committee back in 2020. And advocacy groups have once again decried the bill for threatening free speech and access to encryption, and for imperiling the liability protection that allows online service providers to host third-party content. In other words, the bill’s reception has been much the same as it was two years ago. US Senators Lindsey Graham (R-SC) and Richard Blumenthal (D-CT) on Tuesday reintroduced the bill [PDF] claiming that online service providers are disinterested in keeping child sexual abuse material (CSAM) off their platforms. o § Internet Policy/Net Neutrality⠀➾ # ⚓ The_Internet_Is_Just_Investment_Banking_Now⠀⇛ The internet has always financialized our lives. Web3 just makes that explicit. Twitter has begun allowing its users to showcase NFTs, or non-fungible tokens, as profile pictures on their accounts. It’s the latest public victory for this form of … and, you know, there’s the problem. What the hell is an NFT anyway? # ⚓ Web3_use_cases_for_storage_flimsy_for_now⠀⇛ o § Digital Restrictions (DRM)⠀➾ # ⚓ US_right_to_repair_bills_aim_to_make_ownership_great_again •_The_Register⠀⇛ American farmers may soon be able to repair their agricultural equipment without paying the maker of their machinery for the privilege. And owners of other products may also see fewer repair barriers, depending upon how two new pieces of federal legislation are received. The Agriculture Right to Repair Act [PDF], a US Senate bill introduced on Tuesday by Senator Jon Tester (D-MT), aims to force farm equipment makers to provide parts, documentation, software, and tools for repairs to third parties on reasonable terms. The Freedom to Repair Act, introduced to the House of Representatives on Wednesday by US Representatives Mondaire Jones (D-NY) and Victoria Spartz (R-IN), promises to “legalize repairing what you own or taking it to the repair shop of your choice” by revising copyright law. # ⚓ Remote_code_execution_vulnerability_in_Samba_due_to_macOS interop_module⠀⇛ An exploit in Samba 4 allowed remote code as root due to a bug in its support for Mac clients. It’s fixed in 4.13.17, 4.14.12 and 4.15.5, and in case you can’t update, there are patches. The vuln is being tracked as CVE-2021-44142 and received a CVSS rating of 9.9. [...] Early versions of what was then called OS X used Samba to do this, but after Samba switched to GPL3, Apple dropped Samba in OS X 10.7, and switched to its own implementation. o § Monopolies⠀➾ # § Patents⠀➾ # ⚓ Purdue_University_lawsuit_says_Google_copied smartphone_technology [Ed: Google is no good, but universities funded by the public turning into parasites isn't good either]⠀⇛ Purdue University’s Purdue Research Foundation has sued Google LLC in Texas federal court, alleging that Android software for eliminating programming errors in smartphones copies parts of its professors’ invention. The foundation asked the U.S. District Court for the Western District of Texas for royalties and an undisclosed amount of money damages on Tuesday based on Google’s alleged willful patent infringement. The complaint said two professors and two students at the West Lafayette, Indiana university invented the patented technology, which detects software programming errors that could affect a mobile device’s power management. Purdue said that after a Google engineer posted an article about one of the professors in an Android forum in 2012, another Google engineer found and incorporated code disclosed by the inventors into Android software. # ⚓ BlackBerry_offloads_its_‘legacy’_patents_–_some_of the_stuff_that_made_its_phones_hum⠀⇛ # § Copyrights⠀➾ # ⚓ U2_Share_Acoustic_‘Sunday_Bloody_Sunday’_With_New Lyrics⠀⇛ Bono and the Edge have released an acoustic version of U2′s “Sunday Bloody Sunday,” complete with updated lyrics in the final verse, to coincide with the 50th anniversary of the titular Bloody Sunday massacre. You can watch the performance below. The opening track on the band’s landmark 1983 album War was inspired by the Bogside Massacre, which took place on Jan. 30, 1972, when British soldiers shot 26 unarmed civilians during a protest march in Derry, Northern Ireland, ultimately killing 14 people. The black-and-white performance video is intercut with footage from the massacre. # ⚓ Sound_Library,_opens_use_of_Pokémon_Diamond_and_Pearl soundtrack⠀⇛ While some game companies have been busy purging their music libraries from content creation platforms like YouTube, The Pokémon Company has officially made some of the iconic music from its franchise available for anyone to use globally. Starting today, if you weren’t part of the system’s original launch in Japan in late 2021, anyone can access the new Pokémon DP Sound Library, a digital resource where you can listen to or download music from the official Pokémon Diamond and Pearl soundtrack for use in content creation and even some performances. # ⚓ Attack_on_Titan:_Japanese_Manga_publishers_sue Cloudflare_•_The_Register⠀⇛ Four major Manga publishers are set to sue internet-grooming firm Cloudflare, on grounds its content delivery network facilitates piracy of their wares. The four companies – Kodansha, Shueisha, Shogakukan and Kadokawa – together dominate the market for Japanese comics and own many iconic properties. The publishers also believe they’re victims of widespread piracy. Japanese media report the companies are therefore going to file a suit against Cloudflare, which they feel facilitates piracy by providing its services to sites that share unlicensed Manga. Cloudflare has seen this movie before: in 2017 Japanese publishers asked it to help take down a pirate Manga site called Mangamura. Cloudflare helped, and Mangamura collapsed. Cloudflare later promised to stop mirroring Japanese sites if it was satisfied the content they host was pirated. ䷩ 𝚕𝚒𝚗𝚎 3597 ╒═══════════════════ 𝐃𝐀𝐈𝐋𝐘 𝐋𝐈𝐍𝐊𝐒 ═════════════════════════════════════════════╕ ⠀⌧ █▇▆▅▄▃▂▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁ 02.06.22⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▂▃▄▅▆▇█ ⌧ Gemini_version_available_♊︎ ✐ Links_6/2/2022:_LibreDWG_0.12.5_and_FOSDEM_2022⠀✐ Posted in News_Roundup at 6:29 pm by Dr. Roy Schestowitz 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇GNOME bluefish⦈ § Contents⠀➾ * GNU/Linux o Distributions o Devices/Embedded * Free_Software/Open_Source * Leftovers * § GNU/Linux⠀➾ o ⚓ Linux_Weekly_Roundup_#168⠀⇛ Welcome to this week’s Linux Weekly Roundup, we had a full week in the world of Linux releases, but I and my family are busy moving and my workstation is packed away, so I couldn’t make any videos of these Linux releases, and my computer is still packed away for a while. So this week, Trisquel 10.0, Garuda Linux 220131, Bodhi Linux 6.1.0 alpha, Nitrux Linux 2022.02.02, Peppermint OS 2022-02-02, Zorin OS 16 “Education”, and Slackware 15.0 was released. o § Audiocasts/Shows⠀➾ # ⚓ Rootdo_Takes_Linux_Minimalism_Way_Too_Far_–_Invidious⠀⇛ Some times Linux people take software minimalism a little bit too far and rootdo is one of those cases, this is minimal replacement to doas which is already excessively minimal. o § Kernel Space⠀➾ # ⚓ Linux_5.17-rc3⠀⇛ Things look fairly normal so far, with a pretty average number of commits for an rc3 release. The diffstat shows that we've had more filesystem activity than is perhaps usual, The filesystem activity is all over, ranging from cifs re-introducing fscache support after the rewrite, to vfs-level error handling fixes, to just regular filesystem-specific fixes (btrfs, ext4, xfs), to some unicode Kconfig cleanups. So it's not one single thing, it just happened that we had more filesystem stuff than is perhaps common at this point. That said, driver fixes (networking, gpu, sound, pin control, platform drivers,scsi etc) still dominate. On the driver side, some reverts to re-enable hw-accelerated scrolling for legacy fbdev devices perhaps stand out. Outside of that, it's a mixed bag of random stuff - the usual arch updates (kvm noise stands out), generic networking and core kernel, and tooling (selftests and perf). And some documentation fixes. Shortlog appended for more details, but I don't see anything that makes me worried for the 5.17 release. Knock wood. Please go test, Linus # ⚓ Kernel_updates_available_for_PCLinuxOS_»_PCLinuxOS⠀⇛ Current kernels: kernel-5.4.177-pclos1-1-1pclos2022.x86_64.rpm kernel-5.10.98-pclos1-1-1pclos2022.x86_64.rpm kernel-5.15.21-pclos1-1-1pclos2022.x86_64.rpm kernel-5.16.7-pclos1-1-1pclos2022.x86_64.rpm # ⚓ Linux_5.16.6⠀⇛ # ⚓ Linux_5.15.20⠀⇛ # ⚓ Linux_5.10.97⠀⇛ # ⚓ Linux_5.4.177⠀⇛ # ⚓ Linux_5.16.7⠀⇛ # ⚓ Linux_5.15.21⠀⇛ # ⚓ Linux_5.10.98⠀⇛ # § Graphics Stack⠀➾ # ⚓ 3dfx_Glide_Coming_to_Linux_with_Support_for_Modern GPUs⠀⇛ A developer has implemented 3dfx’s Glide application programming interface into Mesa’s Gallium3D driver stack for modern GPUs. The implementation allows users to play games that rely on Glide under Linux to run on modern hardware. o § Applications⠀➾ # ⚓ 6_Best_Free_and_Open_Source_Robotic_Process_Automation Tools⠀⇛ Robotic Process Automation (RPA) is a business process automation technology that uses attended or unattended software bots to automate repetitive, tedious, and time-consuming back-end office tasks while users concentrate on high-value tasks. This type of software lets you create ‘bots’ to complete a wide variety of tasks, as well as manage and schedule the bots based on the nature of the task. # ⚓ 9_Practical_Examples_of_the_cut_Command_in_Linux [Ed: It’s a GNU program, not “Linux” command; a_kernel_does_not_have such_tools]⠀⇛ Linux-based operating systems offer many command- line text processing utilities you can use in your day-to-day routine. The cut command is one such text manipulation utility that uses delimiters, bytes, fields, and columns to fetch a required string from a flat-file database or a line. Since a flat-file database does not have a structural relationship and the records are separated with the help of delimiters, cut is an ideal tool to extract characters or bytes of information. This article discusses the cut command in detail and demonstrates some practical examples with different filter options to get you started with the tool. # ⚓ New_release_of_sbuild-qemu_Utilities_|_Christian_Kastner⠀⇛ I just released a new version of the sbuild-qemu utilities as part of sbuild. Notable changes are support for new architectures, and a new sbuild- qemu-boot utility to start a VM and interact with its console directly through the terminal. As a reminder, these utilities leverage functionality in vmdb2, autopkgtest, and sbuild to use QEMU VM images for building and testing packages in strongly isolated environments and/or on foreign architectures and/or that might break the system. [...] However, there’s an autopkgtest issue (#10031002) with the host-guest communication bridge on armhf and on multi-core arm64 (single-core seems to work fine) that currently makes images unusable for sbuild and autopkgtest. I haven’t yet figured out what the problem seems to be, but for the time being, the images can still be used with sbuild- qemu-boot. o § Instructionals/Technical⠀➾ # ⚓ 2_ways_to_Install_OpenRGB_on_Ubuntu_22.04_|_20.04_LTS_– Linux_Shout⠀⇛ Learn the commands to install OpenRGB tools on Ubuntu 22.04 LTS Jammy JellyFish or Ubuntu 20.04 LTS Focal Fossa Linux using the terminal to control RGB lights. OpenRGB earlier known as OpenAuraSDK is free, multivendor software for controlling RGB lighting. The project is focused to provide support for multiple hardware manufacturers’ products to reduce the programs load, which are limited to Windows, superfluous. # ⚓ How_To_Install_Memcached_on_Fedora_35_–_idroot⠀⇛ In this tutorial, we will show you how to install Memcached on Fedora 35. For those of you who didn’t know, Memcached is a high-performance distributed, in-memory caching system. It primarily is used to speed up sites that make heavy use of databases. Memcached has an API with a very large hash table distributed across multiple machines. when a table is full, subsequent inserts cause older data to be purged in the least recently used order. 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 the Memcached on a Fedora 35. # ⚓ Mastodon_Setup_with_Docker_and_nginx-proxy_|_~rriemann⠀⇛ I have been working on a setup with Mastodon that is easy to repeat and share. A setup with very few steps. Please consider that this setup is not enough for a production environment. It requires additional security measures. Please put your recommendations in the comments! :grinning: Our starting point is the docker-compose.yml shipped with the Mastodon code. Why is it not enough? It assumes you setup up proxy with HTTPS endpoints yourself. So let’s integrate this as well in Docker. # ⚓ 3_Ways_To_Install_Skype_In_Ubuntu_22.04_LTS_|_Itsubuntu.com [Ed: But it spyware and vastly better options exist in 2022]⠀⇛ Skype is a popular video-conferencing application. It was bought by Microsoft and thus we started to name it Microsoft skype. Microsoft skype has a massive userbase. It is free to install and use., You can use it on any operating system like Windows, Linux, macOS, and Android. In this post, we will show you the multiple ways to install Skype in Ubuntu 22.04 LTS. # ⚓ Cloudlinux_command_to_install_ALT-PHP,_Nodejs,_Python_from SSH_|_Elinux.co.in_|_Linux_Cpanel/_WHM_blog_|_Linux Webhosting_Blog,_Linux_blogs⠀⇛ If you are in love with SSH or black screen and want to install Cloudlinux ALT-PHP, Nodejs or Python using SSH then you can use below command. # ⚓ WHM_API_to_suspend/unsuspend_account_with_account_summary_| Elinux.co.in_|_Linux_Cpanel/_WHM_blog_|_Linux_Webhosting Blog,_Linux_blogs⠀⇛ If you want to suspend the account using WHM API from SSH and mention the reason of suspension then use below command. # ⚓ WHM_API_to_change_the_main_account_domain_name_from_the_SSH |_Elinux.co.in_|_Linux_Cpanel/_WHM_blog_|_Linux_Webhosting Blog,_Linux_blogs⠀⇛ If you want to change the cpanel hosting account domain name using SSH or whmapi then you can run below command. # ⚓ How_to_install_Ardour_on_a_Chromebook⠀⇛ Today we are looking at how to install Ardour on a Chromebook. Please follow the video/audio guide as a tutorial where we explain the process step by step and use the commands below. # ⚓ Install_Build_Essential_Tools_On_Ubuntu_22.04_LTS_| Itsubuntu.com⠀⇛ Tutorial To Install build essential tools on Ubuntu 22.04 LTS. You can also follow this tutorial to install build essential tools on Ubuntu 20.04 LTS. Build essential is not a software or application. Build essential is a meta-package that is required to compile the application on Linux. It includes the GCC/g++ compilers and libraries required to compile software written in C and C++. You need build-essential tool in your Linux to compile the program or source code. # ⚓ Install_PHP_Mcrypt_Extension_On_Ubuntu_22.04/Debian_ [Updated]_|_Itsubuntu.com⠀⇛ Tutorial To Install PHP Mcrypt Extension On Ubuntu 22.04/Debian [Updated] PHP developers have removed it from the PHP package bundle because of no further development in Mcrypt. Some of the alternatives to Php Mcrypt are Sodium (available as of PHP 7.2.0) and OpenSSL. But if you still want to use it then this tutorial is for you where we are going to show you the process to install PHP Mcrypt extensions on Ubuntu 22.04 LTS. # ⚓ Install_Kubernetes_Cluster_on_Centos_8_With_Kubeadm_and CRI-O⠀⇛ This guide will teach you how to deploy a Kubernetes Cluster on CentOS 8 by using kubeadm and with CRI-O Container runtime # ⚓ How_to_install_Microsoft_Teams_on_Zorin_OS_16_–_Invidious [Ed: This is spyware; better use something else]⠀⇛ # ⚓ vga=792_removed_from_legacy_boot_mode⠀⇛ When the Linux kernel is booted on a PC with legacy-BIOS firmware, the screen starts up in a text-mode. This is different from the graphics modes — the former just renders text characters and cannot display graphics. However, if the kernel passes a “vga=” or “video=” parameter, the video can be flipped into a graphics mode. I introduced “vga=792″ a few years ago for legacy-BIOS bootup, so as to display a logo and also to be able to run GUI apps within the initrd. I experimented with GUI apps to ask for keyboard layout and password. Windows computers manufactured from 2012 onwards have UEFI firmware, and this does startup in a graphics mode, so no parameter is required on the kernel commandline. # ⚓ How_to_fix_missing_Linux_header_error_for_VMware Workstation_–_TREND_OCEANS⠀⇛ I tried to run VMware Workstation to install a secondary operating system to test functionality, but it flagged me an error: “VMware Kernel Module Updater: Kernel header X.X.X-X-amd64 were not found.” Intentionally I ignored the message and clicked on “Install” to proceed with the installation. As a result, I got another error which stated, “C header files matching your running kernel were not found”. # ⚓ How_To_Set_Up_An_SFTP_Server_On_Rocky_Linux_8_|_LinuxTeck⠀⇛ SFTP (SSH File Transfer Protocol) is also called Secure FTP. It is a method for uploading and downloading files over an encrypted connection between two computers. Unlike FTP and FTPS, it works differently. Since SFTP is built upon the SSH (Secure Shell) protocol, version 2.0, it supports the full functionality of SSH, such as public-key encryption, to provide strong user authentication and secure encrypted communications over any reliable data stream. Although SSH is used in this context, it may also be used to transfer management information over VPNs and to secure file transfers using Transport Layer Security (TLS). SSH is a client-server protocol that allows for secure communication. The Internet Engineering Task Force (IETF) developed and adopted SFTP to replace insecure shell protocols in 2006; it is an extension of SSH 2. FTP is a tool used for transferring data between computers. This service is no longer popular because it lacks security since this protocol reveals sensitive data and credentials in plain text. Hackers can easily steal data by using this protocol. Therefore, we recommend using SFTP in place of FTP, as it is more secure than the simple file transfer protocol (FTP and FTPS), and you can also protect your data with encoding features, cryptographic hashes, password sniffing, and authentication on the server and the client. # ⚓ How_To_Install_Laravel_on_CentOS_Stream_9_–_idroot⠀⇛ In this tutorial, we will show you how to install Laravel on CentOS 9 Stream. For those of you who didn’t know, Laravel is the most popular PHP framework which is free and open source. Laravel has been developed as a framework that is based on PHP integrating open-source that has multiple tools for creating web applications of all kinds of sizes and complexity. 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 the Laravel PHP framework on CentOS 9 Stream. # ⚓ How_To_Install_Syncthing_on_Debian_11_–_idroot⠀⇛ In this tutorial, we will show you how to install Syncthing on Debian 11. For those of you who didn’t know, Syncthing is a free and open-source file syncing application used to sync files between multiple remote devices over the internet. Syncthing does not upload your files to a central server like Nextcloud but exchanges your data directly between your devices. All your data is encrypted with TLS when transmitting between your devices. Syncthing is available for Linux, BSD, macOS, Windows, Android, and Solaris. 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 Syncthing remote file synchronization on a Debian 11 (Bullseye). # ⚓ A_practical_solution_for_GNU/Hurd’s_lack_of_drivers: NetBSD’s_rumpkernel_framework⠀⇛ GNU/Hurd is the original Free Software operating system started in the 1980s. Its microkernel design has been evolving over the years and the project has not quite hit mainstream use. I believe this is due to one main reason: the lack of drivers for peripherals and hardware. In this talk, I explain how NetBSD kernel drivers have been reused in a microkernel setting and demonstrate their use to boot up a GNU/Hurd system via a userspace rump disk driver, with a driverless Hurd kernel, gnumach. The ACPI management, PCI management, and actual driver are in separate processes with RPC interfaces between them, which separates out their debugging, licencing concerns and execution. I believe this aligns with the original vision for the operating system, (as a Hurd of servers). # ⚓ How_to_instal_Icinga2_on_Ubuntu_20.04_LTS_Focal_–_Linux Shout⠀⇛ Learn the steps to install the Icinga monitoring solution on Ubuntu 20.04 LTS Focal Fossa desktop or server using the command terminal, in this tutorial. What is Icinga? Icinga is an open-source monitoring software platform available as a standalone solution that was originally released as a variant of Nagios. Unlike Nagios, Icinga has a modular architecture and a multi-threaded design. The web interface comes in different variants, which makes Icinga particularly adaptable. Similar to Nagios, the software can be expanded. However, it differs in that the configuration takes place via the web interface and not via configuration files. o § Games⠀➾ # ⚓ Best_Linux_Gaming_Distros_In_2022_For_Gamers⠀⇛ List Of Best Linux Gaming Distros In 2022 For Gamers. Gaming on Linux-based operating systems is a different experience. These days Linux is providing more support for various games. Game developers are slowly turning their attention to the Linux distros and they have started to develop games for the Linux distros too. You are at the right blog post if you are looking for the best Linux gaming distros in 2022 for gamers. o § Desktop Environments/WMs⠀➾ # § K Desktop Environment/KDE SC/Qt⠀➾ # ⚓ Status_update:_Mass_packaging,_and_mass_learning_– post_#2⠀⇛ As I had mentioned in my last post, I already knew the basics of packaging. Flatpak is certainly new for me though. I have used Flatpaks, but never published them. It was easy to learn packaging and writing manifests. I submitted a couple of easy applications to Flathub before the contribution period started, so as to get a good idea of what I’ll be doing during the coming weeks. o § Distributions⠀➾ # ⚓ Tails_vs._Linux_Kodachi:_Which_Privacy_Protection_Distro Should_You_Choose?⠀⇛ When it comes to maintaining privacy on Linux, you have two options: Tails and Linux Kodachi. But which one should you go for? Let’s find out. When it comes to privacy protection, you can’t beat Linux. And for those who want the ultimate in privacy and security, two Linux distributions are leading the way: Tails and Linux Kodachi. Both distributions are self-contained, portable, and use the latest technologies to allow you to remain anonymous online without leaving any trace of your activity when you’re done. But what are the differences? And which ultra- private Linux distribution is right for you? We’re going to answer these questions by taking a look at the overall goals of these two specialized Linux distributions, how they are alike, and what makes them different. # § Slackware Family⠀➾ # ⚓ Slackware_Cloud_Server_Series,_Episode_4: Productivity_Platform⠀⇛ Welcome to the fourth episode in a series of articles that I am writing about using Slackware as your private/personal ‘cloud server’. Check out the list below which shows past, present and future episodes in the series, if the article has already been written you’ll be able to click on the subject. # § Debian Family⠀➾ # ⚓ Free_Software_Activities_for_2021⠀⇛ Most of my contributions to Free software continue to happen within Debian. As part of the Data Protection Team I responded to various inbound queries to that team. Some of this involved chasing up other project teams who had been slow to respond – folks, if you’re running a service that stores personal data about people then you need to be responsive to requests about it. Some of this was dealing with what look like automated scraping tools which send no information about the person making the request, and in all the cases we’ve seen so far there’s been no indication of any data about that person on any systems we have access to. Further team time was wasted dealing with the Princeton-Radboud Study on Privacy Law Implementation (though Matthew did the majority of the work on this). The Debian Keyring was possibly my largest single point of contribution. We’re in a roughly 3 month rotation of who handles the keyring updates, and I handled 2021.03.24, 2021.04.09, 2021.06.25, 2021.09.25 + 2021.12.24 For Debian New Members I’m mostly inactive as an application manager – we generally seem to have enough available recently. If that changes I’ll look at stepping in to help, but I don’t see that happening. I continue to be involved in Front Desk, having various conversations throughout the year with the rest of the team, but there’s no doubt Mattia and Pierre-Elliott are the real doers at present. I did take part in an NM Committee appeals process. In terms of package uploads I continued to work on gcc-xtensa-lx106, largely doing uploads to deal with updates to the GCC version or packaging (8 + 9). sigrok had a few minor updates, libsigkrok 0.5.2-3, pulseview 0.4.2-3 as well as a new upstream release of sigrok CLI 0.7.2-1. There was a last minute pre-release upload of libserialport 0.1.1-4 thanks to a kernel change in v5.10.37 which removed termiox support. # § Canonical/Ubuntu Family⠀➾ # ⚓ The_Edge_of_the_Cloud_is_Now_in_Space_–_Parabolic Arc⠀⇛ The successful Lonestar demonstration mission included pivotal contributions from the digital artist Cecilie Waagner Falkenstrøm and her software team at ARTificial Mind with Niels Zibrandtsen of the Mind Future Foundation, open source software leader Canonical Ltd., and space commercialization leader Redwire Space. ARTificial Mind provided the digital content and blockchain capabilities. Canonical provided a unique “edge of network” kernel of Ubuntu Linux, the leading operating system for container, Cloud and hyperscale computing, to operate on the constrained space hardware aboard the ISS. Redwire Space leveraged their existing server hardware on the ISS from their microgravity 3D printing capability. Lonestar brought the concept and the team together in support of its customers in its work to bring data to the edge. o § Devices/Embedded⠀➾ # § Open Hardware/Modding⠀➾ # ⚓ The_Q2,_A_PDP8-Like_Discrete_Transistor_Computer_| Hackaday⠀⇛ [Joe Wingbermuehle] has an interest in computers-of-old, and some past experience of building computers on perfboard from discrete transistors, so this next project, Q2, is a complete implementation of a PDP8-like microcomputer on a single PCB. Like the DEC PDP-8, this is a 12-bit machine, but instead of the diode-transistor logic of the DEC, the substantially smaller Q2 uses a simple NMOS approach. Also, the DEC has core memory, but the Q2 resorts to a pair of SRAM ICs, simply because who wants to make repetitive memory structures with discrete 2N7002 transistors anyway? [...] A 40-pin header was added, for programming via a Raspberry Pi in case the front panel programming switches are proving a bit tedious and error prone. # ⚓ How_to_Build_a_Morse_Code_Receiver_with_Raspberry_Pi |_Tom’s_Hardware⠀⇛ This tutorial is the second in a two part series for building a building-to-building morse code communications system. In it, we’ll explore how to create a morse code receiver using a Raspberry Pi and a Wyze camera. In a prior article, we explained how to build a morse code transmitter light with Raspberry Pi so this is for the receiving end of the communication. I recently moved into a new place, and discovered that my friend and I live in buildings that face each other. We’re about a kilometre apart, but both our balconies have line of sight to each other. I’ve always wanted to build a communications network with my friends since I was a kid, so I dusted off an old book about Morse, one of my Raspberry P’s and got to work. I’m a big fan of mixing old and new technologies, so instead of using something modern, I decided to use Morse code. This project is the second (and more difficult) part – receiving and interpreting morse code. Thankfully morse has constant time values for each component of the message, and we use that – with some error bands – to make assumptions about which letters are being transmitted based on the length of the light pulses. Here’s how to do it. # ⚓ Designing_devices_for_long-term_care_and_reuse⠀⇛ I love charity shops (what are called thrift shops in the US). In the UK they are so popular they account for almost half of all stores in some shopping streets. You can give unwanted clothes, furnishings, kitchen items, records, CDs, DVDs and books. Items are checked, cleaned and resold for pennies. The profits go to causes like health research, foreign aid, hotlines for abuse, suicide or drug problems, veterans help, animal welfare, and children’s aid. You can pick up great bargains like an expensive designer jacket or a rare, collectable music album. But mysteriously, a notable absence in many charity shops is technology. That seems strange because each year we throw away 50 million tons of phones, tablets, games consoles, remotes, TV screens, headphones, laptops, and digital cameras. Most end up crushed and exported to low-wage recycling facilities in countries with lax environmental regulations. [...] If adults shared phones and computers the way that children swap toys it would be much harder to tie individuals to digital actions. To this end there are two forms of propaganda akin to the “war against public transport” in the USA and elsewhere. One message suggests that sharing is a low status behaviour. The other spreads fear about “security and safety”. By pushing people to form psychological attachments to devices and to identify with their phone as a brand symbol and extension of themselves, advertisers insinuate an unmet need to carry a personal device. Just as open WiFi sharing was besmirched by the spectre of terrorists and child molesters using “your internet”, portraying sharing as a dirty, unhygienic affair like drug addicts sharing needles, shuts down our openness and willingness to efficiently use fewer devices. This over-individuation has led people to misuse smartphone technology, overloading one specific device as a citadel of personal data, identity, connection and access, and creating a single point of catastrophic failure or loss. Technically, this is an awful design. A better technical design to discourage waste is if devices are designed to be shared. How does this work? The personalised parts of a phone or tablet are a separate module from the “sharable” body. The body would contain the radio components, battery and display, while a small, easily swappable private part (a users enclave) would contain storage, contacts, call credits and private keys. This was the original idea behind the Subscriber Identity Module (SIM) which was poorly implemented and has been mishandled, or plainly resisted by manufacturers from the get go. Similarly, modern computers have no good reason to contain a hard disk. To maximise reuse, all should boot only from removable storage and explicitly retain no state. # ⚓ Open-Hardware_Dog_Treat_Dispenser_is_a_Stepping_Stone For_Behavioral_Research⠀⇛ The principles of open-source hardware are starting to make great strides in scientific research fields. [Walker Arce] tells us about his paper co-authored with [Jeffrey R. Stevens], about a dog treat dispenser designed with scientific researchers in mind – indispensable for behavior research purposes, and easily reproducible so that our science can be, too. Use of Raspberry Pi, NEMA steppers and a whole lot of 3D printed parts make this build cheap (< $200 USD) and easy to repeat for any experiments involving dogs or other treat-loving animals. Even if you’re not a scientist, you could always build one for your own pet training purposes – this design is that simple and easy to reproduce! The majority of the parts are hobbyist-grade, and chances are, you can find most of the parts for this around your workshop. Wondering how this dispenser works, and most importantly, if the dogs are satisfied with it? Check out a short demonstration video after the break. # § Mobile Systems/Mobile Applications⠀➾ # ⚓ The_15_Best_Ways_To_Recycle_Your_Phone_Safely⠀⇛ # ⚓ The_Best_Games_Like_Wordle_for_Android_–_Baikoh, Letterpress,_Typeshift_and_More_–_Droid_Gamers⠀⇛ # ⚓ How_To_Get_Adobe_Photoshop_On_Android⠀⇛ # ⚓ How_to_speed_up_your_Android_smartphone_with_these_8 tips_–_Gizchina.com⠀⇛ # ⚓ Android_12′s_customization_shortcomings_drove_me_back to_third-party_launchers_and_icon_packs⠀⇛ # ⚓ Motorola_MA1_Review:_Wireless_Android_Auto_for_the rest_of_us⠀⇛ o § Free, Libre, and Open Source Software⠀➾ # ⚓ SearX,_an_Alternative_to_Google_Scholar⠀⇛ Do you want to search online for academic papers and journals?

This was one of the first times since 2010 where I had a somewhat solid argument to convince Chrome users to consider Firefox again. Personally however, I was stuck on pre-quantum Firefox up until 2019 due to my reliance on Quicksaver’s “Tab Groups” extension (the successor to the Panorama feature), which eventually got succeeded by Drive4ik’s “Simple Tab Groups” extension, which is an absolute must-have; if you’re a chaos warrior, use it—you’ll thank me later. # § Productivity Software/LibreOffice/Calligra⠀➾ # ⚓ LibreOffice_7.3.0_for_Slackware_15.0_(and_-current)⠀⇛ LibreOffice Community Edition 7.3.0 was released last week… on the day we were preparing the Slackware 15.0 release. You’ll forgive me that my focus was elsewhere and that it took until today to upload a new set of packages for Slackware 15.0 and -current. The main selling point of the 7.3 release cycle is better interoperability with Microsoft’s Office file formats. Note that the Microsoft proprietary file formats are still based on a deprecated standard (since 2008 actually), whereas LibreOffice uses the ISO standard OpenDocument Format. These improvements center on three areas (text copied partly from the release notes)… # ⚓ FOSDEM_2022_–_News_from_the_ODF_Toolkit_(with_Notes) by_Svante_Schubert⠀⇛ You can access and download Svante Schubert’s slides about “News from the ODF Toolkit” which was supposed to be features during FOSDEM 2022 but for some reason didn’t work out. # § FSF⠀➾ # § GNU Projects⠀➾ # ⚓ LibreDWG_–_News:_libredwg-0.12.5_released_ [Savannah]⠀⇛ Fixed many more minor fuzzing errors.

However, [Dan Pastusek] was looking around online and found a small label printer on everyone’s favorite online warehouse for a great price that suggested it supported ZPL. Unfortunately, [Dan] had big dreams for creating a Raspberry Pi-based print station and found the drivers packaged for this particular printer were not ARM compatible. Not quite content to leave it there, he began to chip away at the layers until he had a working driver. ZPL, at its core, is just a language describing ASCII commands transmitted over a serial connection. So while the printer showed up as an endpoint, it wasn’t working as the filters (the part of the driver that knows how to convert from a PNG to ZPL) was x86 only. On Linux, printer drivers also have a PPD file that describes what a printer can handle in paper size and other settings. The PPD file for the little printer gave the first clue. In the ShortNickName field, it identifies itself as HPRT N41, which is a popular HP printer. So this little printer must be a clone of a printer in that family. Notably, they don’t support ZPL. Instead, the HPRT series support TSPL, another printer language developed by TSC. * § Leftovers⠀➾ o § Hardware⠀➾ # ⚓ The_Coolest_Controller_Mod,_Hands_Down_|_Hackaday⠀⇛ Video games are a great way to relax, and sometimes get your heart rate up at the same time. But unless you’re playing something like Dance Dance Revolution, the controls pretty much always require the use of both hands. Even the old Atari controller benefited from using the other hand for support. But what if you don’t have the use of both hands? Or you have a repetitive stress injury? Or you just want to eat cheese curls with chopsticks while you play? [Akaki Kuumeri] has you covered with one of the hands-down greatest uses for 3D printing we’ve seen — a PlayStation DualShock 4 controller modified for one-handed use. If this looks familiar, it may be because [Akaki] made a PS5 controller version a while back, but who can get one of those, anyway? o § Integrity/Availability⠀➾ # § Proprietary⠀➾ # § Security⠀➾ # § Privacy/Surveillance⠀➾ # ⚓ Google_Warned_About_Passcode_Theft⠀⇛ Google told a U.S. lawmaker that it received a warning last May that a European technology company was “siphoning” user passcodes to aid surveillance carried out by foreign governments. Google told Sen. Ron Wyden (D- Ore.) that the company had been tipped off that Mitto may have been “siphoning off two-factor text messages for surveillance companies and their foreign government clients,” according to a Wyden aide. It’s not clear who made the allegation, which, if true, could have allowed foreign governments to access personal accounts.

Statements on the public interest with respect to the effect of import bans help the U.S. International Trade Commission (USITC, or just ITC) as it determines whether to institute investigations and can delegate to the Administrative Law Judge (ALJ) in charge of the investigation the analysis of potential public-interest concerns. # ⚓ No_IP,_no_right_to_information?_CJEU_to_clarify_scope_of article_8_Enforcement_Directive [Ed: This is about trade secrets, not IP, which is a fictional thing and misleading misnomer; Jan Jacobi relies on propaganda terms here...]⠀⇛ Under article 8(1) of the Enforcement Directive (Directive 2004/48/EC) a claimant in infringement proceedings can request a court to order certain parties to disclose information. This so-called ‘right to information’ includes information on the origin of the infringement (e.g. who manufactured the counterfeit goods) and its extent (the quantities produced or the price under which a good was sold). An action to obtain the information can be directed at the infringing party as well as third parties potentially involved in the infringement (producers, distributors etc.). # ⚓ FOSS_Patents:_Ericsson_and_Apple_may_soon_meet_in_Texas court_over_dueling_FRAND_claims:_new_filing_calls_Apple_an “unlicensed_[patent]_infringer”⠀⇛ Reading Ericsson’s late-Friday filings in the two FRAND cases in the Eastern District of Texas creates a bit of a High Noon feeling: a duel is in the air. Just a courtroom duel, fortunately. May I refer you to my Wednesday post on Apple’s reply in support of its motion to dismiss Ericsson’s (earlier-filed) case, which also contains a table that juxtaposes the parties’ procedural preferences. It’s fascinating to see this dispute unfold, with both parties playing the game at the highest level, but with Ericsson possibly having devised a strategy that Apple–no matter how hard and smart it tries–may not be able to thwart. # § Patents⠀➾ # ⚓ The_Unified_Patent_Court_And_Unitary_Patent_– Introduction [Ed: Herbert Smith Freehills intentionally promoting fiction and fake_news in an effort to usher in a totally illegal system they hope to profit from]⠀⇛ A new patent right and patent enforcement system is coming for patent protection in the Europe which is likely to commence at the end of 2022 or early 2023 depending on when the final preparations are in place. # ⚓ UPC_Roadshow_February_2022 [Ed: Meissner Bolte is promoting_a_crime]⠀⇛ The Unitary Patent and Unified Patent Court (UPC) are coming – and Meissner Bolte is hitting the (virtual) Road! # ⚓ Opinion:_QCs_must_shun_limelight_if_juniors_are_to thrive [Ed: When litigation firms bribe the media (including this writer) and hire lobbyists to write/ change the law it's hardly surprising we end up with more lawsuits, i.e. the public pays extortionate fees to people who produce nothing at all]⠀⇛ A senior judge, who predicts a spike in IP cases, says QCs’ tendency to dominate litigation is reducing juniors to mere “tiles on a screen” # ⚓ Vorwerk_wins_against_Lidl_in_dispute_over_kitchen appliance [Ed: This is framed as marketing/promotion for patent litigation firms (the real clients of JUVE) instead of news/reporting, i.e. the usual from JUVE]⠀⇛ Lidl may no longer sell its Monsieur Cuisine kitchen machine. Düsseldorf Higher Regional Court issued the ruling in the second instance in a dispute with household electronics manufacturer Vorwerk. The court found that Lidl infringed a patent held by the German company for its Thermomix kitchen machine. Technically, the patent DE10226940 is for a heating technology used to cook food in the mixing bowl. [...] The dispute concerned German companies only, with Vorwerk not filing actions against the Chinese manufacturers. # ⚓ Dutch_courts_could_have_international_jurisdiction_to hear_FRAND_claims [Ed: Dutch courts have openly_enabled (with_help_from_the_government)_criminals_from_the_EPO get_away_with_crimes; do we want to rely on them for patent disputes?]⠀⇛ The District Court of The Hague has declared both international and territorial jurisdiction to decide on a FRAND case brought against patent pool Access Advance by Turkish television manufacturer Vestel. Access Advance had challenged this assertion based on three of four of its members not being domiciled in the Netherlands. However, the court decided that the parties’ connection to Netherlands-based Philips was strong enough to warrant the setting of a FRAND rate to cover the whole patent pool. As such, Vestel’s proceedings against the pool members on the merits of a FRAND licence will continue. This case is unusual in that implementer Vestel commenced proceedings, rather than the patent holder. Overall, the decision could have implications for other patent pools in the Netherlands, especially if the licensor is based in the Netherlands. The outcome of the next set of proceedings could open the door for the Dutch courts to decide FRAND determination. # ⚓ Exclusive:_Nordic_IP_chief_quit_FSA_board_before Nokia_licensing_deal [Ed: This is clearly limited to patents; the term “IP” is nonsense, but those who call their own site after this propaganda term will never wish to admit it (they’re paid to relay the false narratives)]⠀⇛ Nordic Semiconductor’s legal head told Managing IP it was time to change tack on the end device v component level licensing debate # ⚓ UK_IPO_launches_call_for_views_on_the_Designs_System [Ed: UK-IPO pretends to care what the British public thinks while actually adopting the proposals of foreign lobbyists]⠀⇛ The designs system enables rights holders to protect designs and enforce their rights. We are seeking views and evidence from users of the system so that we can ensure the UK’s designs framework works for the businesses, consumers and designers that use it.

[...] The following are some recently issued patents that include third party submissions if you want to look through the file histories: 11,228,023; 11,225,200; 11,224,546; 11,224,456; 11,228,055; 11,221,486; 11,220,614; 11,219,722; 11,219,166. # ⚓ FDA_Approves_Generic_Restasis [Ed: The lack of generics up until now, due solely to patents, made the lives of many people a lot worse]⠀⇛ On Wednesday, the U.S. Food and Drug Administration announced approval to Mylan Pharmaceuticals for a generic form of Allergan’s RESTASIS® (Cyclosporine Ophthalmic Emulsion 0.05%) product for treatment of chronic dry eye. RESTASIS® is “a calcineurin inhibitor immunosuppressant indicated to increase tear production in patients whose tear production is presumed to be suppressed due to ocular inflammation associated with keratoconjunctivitis sicca.” # ⚓ Public_consultation_opens_on_latest_EPC_and_PCT-EPO Guidelines [Ed: Criminals who took over the EPO pretend to care about the general public while breaking the law in every aspect]⠀⇛ The latest version of the EPC and PCT-EPO Guidelines will come into force on 1 March, and a preview version has been published today. In parallel the EPO has opened its public user consultation on these latest Guidelines. Users are invited to submit their comments in any one of the EPO’s three official languages via an online form. The deadline for contributions is 15 April 2022. [...] We encourage all patent professionals and interested stakeholders to take this opportunity to comment on the EPC and PCT-EPO Guidelines. The anonymised comments will be discussed with the members of the SACEPO Working Party on Guidelines in a meeting scheduled for May 2022. # ⚓ Top_4_changes_to_the_2022_EPO_Guidelines_for Examination [Ed: Constant and chronic liars, who endlessly lie about UPC (Simmons & Simmons LLP), which is illegal, rooting for corrupt_EPO_management instead of condemning it; the unlawful guidelines do not comply with EPC; of course Simmons & Simmons LLP is happy to use the EPO’s words to promote software patents, disregarding common sense and so_much_more]⠀⇛ The European Patent Office has today published an advance preview of its annual update to the Guidelines for Examination which will come into force on 1 March 2022. [...] Following G 1/19, which maintained the status quo by applying COMVIK to assess computer- implemented simulations, G-II, 3.3.2 has been updated to make it clearer how to approach establishing whether or not there is a technical effect when the claimed subject matter involves a simulation. The new discussion delineates different situations where simulations are involved, covering the gamut from purely numerical simulations with no direct link with physical reality, to simulations which interact with the outside world. Important concepts that were reinforced in G 1/19 are now emphasised in the Guidelines. In particular, that output data of a simulation may have a ‘potential technical effect’ – a technical effect that would be produced when the data is used according to an intended technical use. Correspondingly, G-VII, 5.4.1 has been updated to refer to G-II, 3.3.2 when formulating the objective technical problem for mixed technical and non-technical claims. # ⚓ Proven_Networks_proven_to_be_PAE_in_public_interest statements_—_Unified_Patents⠀⇛ On January 27, 2022, Unified Patents filed a public interest statement in the ITC on the Proven Networks v.

Velos Media had designated the ’086 patent as essential to the HEVC standard. During reexamination, to overcome the rejections, Velos was forced to greatly amend the claims of the ’086 patent such that they are no longer essential. # ⚓ MBHB_Webinar_on_Patent-Eligibility_and_the Expanding_Notion_of_Abstraction [Ed: Patent litigation profiteer Michael Borella has taken his dishonest lobbying from blog_as_a_platform to “webinar” (ads)]⠀⇛ McDonnell Boehnen Hulbert & Berghoff LLP will be offering a live webinar entitled “The Expanding Reach of the Abstract Idea — What Is and Is Not Patentable Eight Years After Alice” on February 16, 2022 from 10:00 am to 11: 15 am (CT). In this presentation, MBHB attorney and Patent Docs author Michael Borella will review the current state of patent eligibility and how the exclusionary principle is licking its lips. But in addition to sounding the alarm, he will offer attendees an unconventional take on what courts are actually looking for in order for claims to be found eligible — valuable information that might just save your inventions from judicial doom. # § Trademarks⠀➾ # ⚓ The_TTABlog®:_CAFC_Affirms_TTAB:_“.SUCKS”_(Stylized) Fails_to_Function_as_a_Source_Indicator_for_Domain Registry_Operator_Services⠀⇛ In October 2020, the TTAB upheld failure-to- function refusals of the term .SUCKS in standard character and in stylized form (shown below), for domain registry services related to the gTLD in the proposed mark. [TTABlogged here]. Applicant Vox Populi appealed only the refusal of the stylized version of the mark, arguing that the stylization makes the proposed mark registrable. The court, however, found no error in the Board’s conclusion that the stylized form of .SUCKS fails to create a commercial impression separate from the unregistrable term .SUCKS. In re Vox Populi Registry Ltd., Appeal No. 2021-1496 (Fed. Cir. February 2, 2022) [precedential (Opinion by Judge Timothy B. Dyk). [...] The question, then, was whether the stylization of the stylized form rendered that mark registrable.The court observed that this issue requires a subjective determination “based on a viewer’s first impression.” The court cited several well known TTAB decisions as examples (stylized versions of CONSTRUCT-A-CLOSET (registrable), JACKSON HOLE (registrable), BUNDT (unregistrable), and SADORU (unregistrable), and then concluded that the Board did not err in ruling that the stylized form of .SUCKS fails to create a separate commercial impression. # ⚓ TTABlog_Test:_How_Did_These_Four_Section_2(d)_Appeals Turn_Out?⠀⇛ In January 2022, the Board decided twenty-two (22) appeals from Section 2(d) refusals.

These bug fixes improve various components to work as expected, such as Toolbar fields, which again use the units selected by the user as display units in Document preferences. Also improved in Inkscape 1.1.2 is support for graphic tablet pens that have a built-in eraser tip as they now again automatically switch to the correct tool.

If a 90s laptop was too bulky, there was always the IBM PalmTop which packed punch for its size-to-weight ratio, and for the era it was created in. [Mingcong Bai] still has one of these antiques and decided to see if it was still usable by loading a customized Linux distribution on it. The PalmTop sported modest hardware even for its time with an Intel 486SL running at 33 MHz with 20 MiB of RAM. This one also makes use of a 1 GB CompactFlash card for storage and while [Mingcong Bai] notes that it is possible to run Windows 95 on it, it’s not a particularly great user experience. A Linux distribution customized for antique hardware, AOSC/Retro, helps solve some of these usability issues. With this it’s possible to boot into a command line and even do some limited text- based web browsing as long as the Ethernet adapter is included. # § Open Hardware/Modding⠀➾ # ⚓ OpenBikeSensor_Measures_Close_Calls_|_Hackaday⠀⇛ Cycling is fun, healthy, and good for the environment. But unfortunately it’s not always the safest of activities, as inconsiderate drivers can be a significant hazard to cyclists. Several countries, including Germany, France, and Belgium have introduced legislation mandating a minimum passing distance of at least 1.5 meters between cars and bikes. Enforcing such a rule is tricky however, and without accurate data on average passing distances it’s hard to know how many drivers are following it. Enter OpenBikeSensor, an open-source hardware and community science project designed to gather exactly this information. Currently in its prototype phase, it aims to make a simple bike-mounted sensor that measures the lateral distance to any passing vehicles. The resulting data is collected online to generate maps highlighting danger zones, which can ultimately be used by city planners to improve cycling infrastructure. # § Mobile Systems/Mobile Applications⠀➾ # ⚓ The_best_habit_tracker_apps_for_Android_–_Android Authority⠀⇛ # ⚓ Android_users_warned_over_Google_Play_Store_password security_app_that_can_steal_your_money_–_delete_it NOW⠀⇛ # ⚓ Renders_of_Android-powered_Pixel_tablet_surface; images_are_based_on_Google_patent_–_PhoneArena⠀⇛ # ⚓ Android_Phone_Going_Straight_To_Voicemail?_Try_This_| Screen_Rant⠀⇛ # ⚓ This_Samsung_Galaxy_S22_news_will_have_all_Android rivals_worried_|_Express.co.uk⠀⇛ o § Free, Libre, and Open Source Software⠀➾ # § Programming/Development⠀➾ # ⚓ Twist_Promises_Easier_Quantum_Programming_| Hackaday⠀⇛ We keep trying to learn more about quantum computers. But the truth is, the way we program quantum computers — or their simulators — today will probably not have much in common with how we program them in the future. Think about it. Programming your PC is nothing like programming the ENIAC. So we expect we’ll see more and more abstractions over the “bare metal” quantum computer. The latest of these is Twist, from MIT. According to the paper (and the video, below), Twist expresses entangled data and processes in a way that traditional programmers can understand. The key concept is known as “purity” of expressions which helps the compiler determine if data is actually entangled with another piece of data or if any potential entanglement is extraneous. A pure expression only depends on qubits it owns, while a mixed expression may use qubits owned by other expressions. # ⚓ Write_code_inspired_by_Shakespeare_with_esolang_| Opensource.com⠀⇛ Maybe you’ve heard that playwright William Shakespeare contributed 1,700 new words to the English language. But did you know that he has an entire programming language as well? SPL (Shakespeare programming language) was created to make source code resemble Shakespeare plays. It is an esoteric language, also known as an esolang. An esolang is a computer programming language designed to experiment with weird ideas, create a challenge for programmers, or simply serve as a source of amusement, rather than for practical use. * § Leftovers⠀➾ o ⚓ Hendrix_in_Our_Time⠀⇛ Three completed studio albums: Are You Experienced?  (1967), Axis: Bold as Love(1968), Electric Ladyland  (1969).

However, in the run-up to the upcoming 2024 Olympics in Paris, organisers in Europe are also looking into the possibility of increasing biometric mass surveillance at sporting events. In doing so, politicians would deliberately accept the loss of privacy, limitation on freedom of expression, and the division of society and discrimination. o § Defence/Aggression⠀➾ # ⚓ Opinion_|_Tone-Deaf_Navy_Lawsuit_Wrongfully_Calls_State_of Hawaii_Shut_Down_of_Leaking_Jet_Fuel_Tanks_‘Erroneous’⠀⇛ Two lawsuits filed on February 2, 2022 by the U.S. Department of Justice on behalf of the Department of Defense and the Department of Navy challenge the State of Hawaii’s emergency order to shut down and defuel the leaking 80-year-old jet fuel tanks. These lawsuits have created another public relations nightmare for the U.S. Navy and the Department of Defense as residents of O’ahu have expressed their dismay and outrage to the continuing threat of jet fuel to their drinking water aquifer. In November 2021, the Red Hill tank system leaked jet fuel into the drinking water of 93,000 residents in military housing around Pearl Harbor Navy Base and Hickam Air Force base. # ⚓ Opinion_|_Is_Congress_Willing_to_Fix_Biden’s_Failed_Yemen Policy?⠀⇛ # ⚓ Police_in_Hesse_expand_use_of_„Super_Recognisers“⠀⇛ In Frankfurt, two full-time officers are now working for the humanoid facial recognition.

Since 1823, we have claimed the right to defend our hemisphere in accordance with the Monroe Doctrine, and now Russia is putting into practice a similar policy against a militarized Ukraine. The parallels are close; the reasons for a defensive posture, obvious. Yet Secretary of State Antony Blinken has said the US no longer believes that there are spheres of influence. Or rather, there is just one sphere: the ever- expanding terrain of legitimate Western democracies approved by NATO. This worldview—an immediate, unexamined consequence of the fall of Soviet communism in 1991—cut a clear path through the Clinton, George W. Bush, Obama, and (for all the fuss) Trump administrations. But there were two bumps that might have served as a warning. In 2008, Georgia’s attack on Russian troops in South Ossetia was answered with decisive and crushing force, and in 2014, Russia responded to the US-backed coup in Ukraine by annexing Crimea. Vladimir Putin explained that when he next visited Sevastopol, he would prefer not to be greeted by NATO sailors on the Black Sea. # ⚓ The_Politics_of_the_Capitol_Insurrection_Are_Spreading Across_the_Country⠀⇛ There was a sense, on the afternoon of the Capitol insurrection, that violent white American Trumpism had reached its apex. But by the next morning, as Republican politicians and right-wing media figures began rewriting history in real time—claiming antifa actually did it, pretending the insurrectionists merely went on self-guided tours of the building and “took selfies,” portraying the white mobs as victims—it became clear that the previous day’s act of sedition hadn’t been the final spasm of white supremacist anti-democracy but the harbinger of white supremacist anti-democracy to come. And those who support and excuse it are attempting to give the anti-democratic violence of the insurrection a veneer of respectability by dressing it up in the language of election integrity. o § Finance⠀➾ # ⚓ Opinion_|_The_Federal_Reserve_Is_About_to_Give_US_Workers the_Shaft⠀⇛ o § AstroTurf/Lobbying/Politics⠀➾ # ⚓ House_Dems’_New_Anti-Progressive_PAC_Is_Funded_by_Corporate Lobbyists_and_PACs⠀⇛ # ⚓ Forced_Sterilizations_Are_Still_Legal_in_31_States,_New Report_Shows⠀⇛ # ⚓ South_Dakota_Governor_Signs_“Cruel_and_Dangerous” Transgender_Athletes_Ban⠀⇛ # ⚓ Stop_the_Saber-Rattling!_Greens_Call_for_Immediate Diplomacy_to_Resolve_Ukraine_Crisis⠀⇛ Green Party leaders called on the Biden administration to immediately cease escalating military tensions and pursue a diplomatic solution to the Ukraine crisis. In response to fear of Russian military incursion into Ukraine, this week U.S. troops from a number of bases across the country have been put on high alert for possible deployment to Europe, and the U.S. has sent a second batch of weapons to Ukraine. Paramilitaries trained by the CIA in the U.S. are reportedly advising counterparts in eastern Ukraine, even while Democrats in Congress are fast- tracking for passage this week a bill for $500 million more in weapons for Ukraine. The Biden administration’s threats of military buildup and sanctions against Russia are escalating this crisis to an increasingly dangerous level. The one-upmanship and nuclear and military rhetoric must cease immediately. The only gains in a military clash are for military contractors. “The risk of this conflict erupting into a disastrous large-scale war is too great to ignore in order to please arms makers and bellicose politicians,” said Madelyn Hoffman, 2020 Green Party candidate for U.S. Senate from New Jersey and a member of the Green Party Peace Action Committee (GPAX). “Specifically, in the matter of Ukraine, the U.S. should negotiate a reduction of military forces in the conflict zone. We call on the Biden administration to pursue a diplomatic solution. We urge the Biden administration to heed European Union allies France and Germany calling for diplomacy, to acknowledge that Ukraine leaders believe Russian invasion is not imminent, and to pursue possible grounds for talks on secondary issues. The United States must also respect Ukraine’s right to self-determination.” o § Freedom of Information/Freedom of the Press⠀➾ # ⚓ Arrests_Aim_to_Silence_Kashmiri_Journalists_and_Human Rights_Defenders_–_Censored_Notebook⠀⇛ India, the world’s largest democracy, continues to use draconian laws to silence and incarcerate journalists and human rights defenders in Kashmir. On February 4, Fahad Shah, founder and editor of the Kashmir Walla was arrested by local police for “uploading anti-national content…to create fear among the public.” On January 6, Kashmiri journalist Sajad Gul was arrested and later booked under the Public Safety Act, which allows for the detention of civilians for up to two years.

The calls came on the 29th anniversary of the Family and Medical Leave Act (FMLA), which provides eligible employees with up to 12 weeks of job- protected leave to care for a new child or take care of one’s own or family member’s illness. But, worker advocates say, the groundbreaking law is sorely insufficient, because the leave is unpaid and FMLA doesn’t cover all workers. o § Monopolies⠀➾ # § Patents⠀➾ # ⚓ Counsel_call_for_transparency_in_China’s_bad-faith screening [Ed: When Sukanya Sarkar says "sources" she means sponsors (for whom she amplifies something for lobbying purposes)]⠀⇛ Sources say China’s measures to tackle bad- faith patent filings have delivered mixed results, and genuine applicants are suffering because of its lack of transparency # ⚓ Counsel_laud_India_SC’s_rare_TM_decision,_but_want more ][Ed: This is about trademarks, but same author.

This is what a partner at a leading German patent litigation firm charges on average per hour in a normal infringement case. “In litigation for US clients, I can charge up to €1,250 per hour,” reveals the partner of a leading German patent litigation firm. In large global patent battles, one patent attorney reports that the wallets of US clients are particularly loose. They can also charge up to €1,200 per hour for such proceedings. In contrast, in 2021, partners in law and patent attorney firms across Europe charged an average of €460 per hour for patent litigation. This is one result of a current survey by JUVE Patent among European patent firms. # ⚓ A_remote_village,_a_world-changing_invention_and_the epic_legal_fight_that_followed [Ed: Instead of feeding people Ocado is just suing people with junk patents that courts already frown upon; of course the EPO played a role]⠀⇛ If your groceries are supplied by Ocado in the U.K. (or Kroger in Cincinnati and Atlanta, or Casino in Paris, for which Ocado supplies technology), you have experienced his legacy. The retail industry increasingly relies on automated warehouses, and the approach that Hognaland pioneered and that Ocado built on, is even more advanced than Amazon’s. AutoStore systems are being used in more than 40 countries, with 29,000 robots on wheels. It would be an inspiring story of inventive genius in logistics, except for one problem: Hognaland’s idea turned out to be so valuable that Ocado adapted it without permission. That set off an ongoing global patent battle between the two companies, with billions at stake. When Ocado won one stage of a U.S. legal case in December, its value rose by more than £1 billion that day, while AutoStore’s dropped. On one side is a quiet, determined Scandinavian company that spent a quarter of a century diligently making its robots work, one step at a time. On the other, an aggressive British disrupter that seized on the idea to turn itself into a juggernaut. And beneath it all, a classic question: does a revolutionary innovation belong to the person who had the idea, or should it belong to the world? # ⚓ American_Manganese_poised_to_add_China_to_its_global patent_portfolio [Ed: US has fallen so far behind that now there’s an effort to secure patents in China rather than the other way around; Chinese_patent_quality_is regarded_as_a_joke]⠀⇛ The Chinese patent office has issued the company with a ‘Notice of Allowance’ for the company’s National Phase Patent Application for its technology RecycLiCo. # ⚓ An_End_To_Adapting_The_Description_To_Allowed_Claims At_The_EPO? [Ed: This board, like all the other boards, isn’t compliant with the EPC; it’s basically a kangaroo court_controlled_by_the_EPO’s_corrupt_and_truly illegitimate_regime]⠀⇛ According to EPO Examining Division practice, once claims are found to be allowable, the description must be “adapted to the claims to avoid inconsistencies between the claims and the description” (The Guidelines for Examination in the European Patent Office, Part F, Chapter IV, section 4.3, paragraph iii1). In a recent decision (T1989/182) an EPO Technical Board of Appeal considered the legal basis for this requirement. # ⚓ Implementing_Regulations_Confirm_The_GCC_Patent Office’s_New_Working_Model [Ed: Overzealous litigation giant Gowling WLG, which spreads fake news for financial gain, is trying to extend its 'patent hegemony' regime to the Gulf]⠀⇛ In January 2021, the Patent Office of the Gulf Cooperation Council (GCC patent office) stopped accepting new GCC patent applications following a meeting of the GCC Supreme Council. This meeting resulted in an amended GCC Patent Regulation being issued in May 2021 and more recently the Implementing Regulations in November 2021. Below we take you through the key takeaways for the new Regulations. A review of the Regulations confirm the position set out in the amended GCC Patent Regulation, that the GCC Patent Office will resume handling patent applications, their examination and grant, as well as annuities. However, the significant change from pre- January 2021 applications, is that the GCC Patent Office will only do so upon request from a national patent office in the GCC. Rather than file directly with the GCC Patent Office, applicants will have to file for a GCC patent through a national office. # ⚓ Nokia_4G_patent_upheld_by_European_Patent_Office, stronger_than_ever_thanks_to_Daimler’s_wasteful litigation_effort [Ed: Nokia leverages patents from the EPO to tax everything, and to nobody’s actual advantage]⠀⇛ The dispute with Daimler is the gift that keeps on giving to Nokia. The case settled seven months ago, but yesterday Nokia’s EP2550762 on “signalling of channel information” got upheld by an opposition panel of the European Patent Office with only a minor amendment, which still allows Nokia to claim that it is essential to the 4G/LTE standard. The patent relates to carrier aggregation (aggregating bandwidth from different parts of the spectrum). Nokia didn’t assert that standard-essential patent (SEP) against Daimler, but it was on a list accompanying Nokia’s infringement notice, so Daimler and its supplier TomTom challenged it, possibly also hoping to drive up Nokia’s litigation costs. Daimler wasn’t actually listed as a party, but their lawyers (Quinn Emanuel) obviously weren’t opposing the patent pro bono. [...] Daimler’s litigation department managed that litigation a bit like people who order whatever item on the restaurant menu is priciest. You could take a burger straight out of McDonald’s, put it on the menu, charge $350, and those types of people would order it even if they could get a filet mignon from wagyu beef at half the price at what would still be an upscale restaurant on the other side of the street. There came a point when others in the organization were no longer prepared to support that wasteful spending. Now they just have to realize at Daimler that it’s a mistake in German patent litigation not to hire interdisciplinary teams consisting of attorneys at law and patent attorneys. Patent attorneys won this one for Nokia. Nokia definitely got a lot of value out of the Daimler dispute. But again, sophisticated tech companies, above all smartphone makers, are the real challenge, provided that can come up with a new challenge to EP’762 as merely rehashing Daimler’s unavailing arguments won’t help. # ⚓ Relief_Announces_That_Collaboration_Partner,_Acer Therapeutics,_was_Issued_U.S._Patent_11,202,767 Covering_ACER-001_Methods_of_Use_for_Treatment_of_Urea Cycle_Disorders_and_Maple_Syrup_Urine_Disease⠀⇛ # ⚓ Worldwide:_For_The_First_Time_In_History_–_Australian Court_Rules_That_Artificial_Intelligence_Can_Be Registered_As_An_Inventor_In_A_Patent [Ed: This has been mostly a source of shame and disgrace to Australia, which got conned_by_buzzwords, lies, and lawyers]⠀⇛ In the last month, the Australian court has set a global legal precedent, according to which an artificial intelligence system can be registered as an inventor under a patent. Although the decision is not a formal legal precedent, it may be the first far-reaching change in the realm of intellectual property, science, technology and business. # ⚓ UK_Court_Rules_Apple_Must_Unconditionally_Commit_To_A FRAND_License_To_Avoid_An_Injunction [Ed: Blackmail (embargo) by patents benefits nobody, even if in this particular case it hurts a nasty company like Apple]⠀⇛ In a recent judgment (Optis Cellular Technology LLC & Ors v Apple Retail UK Ltd & Ors [2021] EWHC 2564 (Pat), 27 September 2021), Meade J, sitting in the England and Wales High Court, gave a decision in a series of trials relating to eight of Optis’s patents in the field of telecommunications. Each of these patents is asserted to be a standard-essential patent (SEP) and was declared to the European Telecommunications Standard Institute (ETSI). # ⚓ T_1989/18:_adaptation_of_the_description_of_a European_patent_application [Ed: Suffice to say, these EPO_tribunals_are_patently_rigged; a dog wagged by its own tail]⠀⇛ Prior to grant of a European patent application, examiners often request the description to be adapted for consistency with the subject matter of the allowable set of claims. This became a more onerous exercise following an update to the EPO Guidelines for Examination in March 2021, which set out a significantly greater range of circumstances in which the description should be adapted. A recent decision from an EPO Board of Appeal considered whether there was legal basis for refusing an application if the description was not adapted to the subject matter of the claims. # ⚓ Progress_for_the_realisation_of_the_Unified_Patent Court [Ed: No, UPC is illegal; as such, it_will_be stopped, just like before…]⠀⇛ The Unified Patent Court (UPC) is a proposed common patent court open for EU member states hearing cases regarding infringement and revocation of European patents (including the new Unitary Patent). If carried through, the Unitary Patent and the UPC represents significant changes to European patent law. In essence, it will create a single approach to patent protection and litigation across the participating EU member states. # ⚓ [Older]Current_Patenting_Issues_In_Europe_Facing_Life Sciences/Biotech_Innovators_And_Effective_Claim Drafting_Strategies_To_Avoid_Pitfalls [Ed: Notice the total disregard for the law; they look at the law as an obstacle to overcome, not obey, in the name of aggression/litigation]⠀⇛ This paper is in two sections. The first relates to current topics, issues and developments in European patent practice in that may be relevant for innovators in the life sciences. As far as possible, this first part tracks the issues discussed from a US perspective in the paper submitted by my co- panellist Courtenay Brinckerhoff of Foley & Lardner LLP, in the hope that US-based readers can better compare the situation in the US with that in Europe. The second part, focussing on differences between US and European practice and how to avoid these differences becoming pitfalls for US applicants, is more timeless – as in general these issues change relatively little over time, and yet they remain problems if they remain unfamiliar. For completeness, both sections include some information on issues that are general to all applicants but equally or especially relevant to those in the life sciences. # ⚓ [Older]_Judge_Albright_Issues_Updated_Standing_Order for_Patent_Cases [Ed: The patent_trolls’_kangaroo court]⠀⇛ The Eastern District of Texas manages more patent cases than any other district court in the United States. # ⚓ Imugene_welcomes_new_chief_medical_officer_and_talks significant_new_patents [Ed: Too much emphasis on patents instead of products; in this case, patents from EPO whose own examiners complain_about_invalid grants]⠀⇛ Imugene’s Leslie Chong discusses with Proactive’s Andrew Scott the appointment of Dr Steven Cha as Chief Medical Officer and a member of the company’s executive management team. IMU has recently received a notice of grant from the Japanese Patent Office which protects its oncolytic virotherapy CF33, including VAXINIA (CF33-hNIS) and CHECKVacc (CF33-hNIS-antiPDL1). The company has also opened the doors to a large and lucrative market for immuno-oncology by securing a Notice of Grant from the European Patent Office for its HER-Vaxx immunotherapy. # ⚓ [Older]_An_Absolute_Novelty_Design_Patent_Trap_for the_Unwary [Ed: Design_patents are a sham]⠀⇛ Global design patent strategies are increasingly being relied upon by retail and consumer products companies as a cost- effective way to protect key product lines. However, it is important to understand the various nuances of global design patent strategies since there are traps for the unwary, most notably in Australia and China. # ⚓ EPO_to_Allow_Applicants_to_File_Early_Requests_to Obtain_a_Unitary_Patent [Ed: EPO knowingly_breaking_the law_yet_again; and since nobody ever holds the EPO accountable for its many crimes even the so-called law firms are boosting these illegal acts for personal (financial) gain)]⠀⇛ The EPO has issued a notice explaining that, in the lead up to the entry into force of the Unified Patent Court (UPC) Agreement, which will make “Unitary” Patents available based on a granted European patent, it will be possible for applicants to file early requests for a European patent to take unitary effect after grant. # ⚓ The_Fundamentals_of_the_Unified_Patent_Court_System and_the_New_Unitary_Patent [Ed: Orrick, Herrington & Sutcliffe LLP cannot help itself; it knowingly_misleads clients_and_lobbies_for_illegal_agenda_using_fake_news strategies]⠀⇛ To understand the impact of the Unitary Patent and the Unified Patent Court, it is helpful to consider the status quo of European patent law. Each European country has its own patent laws, and patents are generally granted with national effect only. # ⚓ The_UPC_Opt-out_for_European_Patents_–_Should_I_Stay or_Should_I_Go? [Ed: For the second time in one week this so-called 'law' firm produced misleading headlines, in order to promote this idea that an illegal system is already here and in force]⠀⇛ For further insights related to the Unitary Patent and the Unified Patent Court click here. Proprietors of European Patents will have the opportunity to avoid jurisdiction of the Unified Patent Court by filing so-called opt- out applications during an initial Transitional Period of at least seven years. An opt-out will remove the jurisdiction of the UPC for the opted-out European Patent and effectively maintain the judicial status quo: Opted-out European Patents can only be enforced or invalidated by national courts in the same way they can now. However, a European Patent can only be opted out so long as it has not yet been the subject of UPC proceedings. For example, once a revocation action has been filed against a European Patent with the UPC, opting out will be impossible. Accordingly, the decision of whether or not to opt-out can be time critical. # ⚓ Germany:_UPC_–_Progress_Towards_The_Start_Of_The Unitary_Patent_System [Ed: Keltie, which has_long promoted_illegal_agenda (breaking of the law does not bother so-called ‘law’ firms), is once again pushing fake news and utterly illegal agenda]⠀⇛ Following delays from Brexit and a constitutional challenge in Germany, the deposit of Austria’s instrument of ratification on the Protocol on Provisional Application to the Agreement on a Unified Patent Court (UPC) in mid January 2022 has started the provisional application period which allows final preparations for the UPC to be made. # ⚓ Unitary_Patent_court:_where_we_are_and_where_we’re going [Ed: Bugnion SpA, with an utter conflict of interest, also maliciously spreads false_“news” in an effort to enforce an illegal and unconstitutional agenda]⠀⇛ # ⚓ EPO_Issues_Guidance_On_Achieving_Unitary_Patent Status_From_Day_1_Of_The_UPC/UP_System_For_European Patent_Applications_Coming_Up_To_Grant [Ed: EPO is (once again) intentionally breaking the law and Herbert Smith Freehills, profiteers of patent trolls, cheer for the criminals]⠀⇛ # ⚓ The_Unitary_Patent_and_the_Unified_Patent_Court_Are Expected_to_Go_Live_in_Less_than_a_Year [Ed: More fake news, as usual, from people with a clear conflict of interest]⠀⇛ The Unitary Patents system – providing for the new Unitary Patent and Unified Patent Court (UPC) – will have a profound impact on patent protection, patent enforcement and patent revocation proceedings in Europe. # ⚓ Unified_Patent_Court_starts_final_preparations [Ed: And yet another large so-called ‘law’ firm is promoting a_crime, based on fake news that it helped promote with other such firms]⠀⇛ Austria deposited its ratification of the Protocol on Provisional Application of the Agreement on a Unified Patent Court as the thirteenth signatory state with the European Council on 18 January 2022. As a result, the phase of provisional applicability of the Agreement on a Unified Patent Court (UPCA) will enter into force. This phase includes the final organisational preparations for the launch of the UPC. The Chairman of the Preparatory Committee, Alexander Ramsay, expects that the UPC could start its work after a preparatory phase of about eight months. Subsequently, Germany as “gatekeeper” is to deposit its instrument of ratification of the UPCA, so that the UPCA will enter into full force four more months later. # ⚓ ILOAT:_Former_EPO_president_Battistelli_violated staff’s_right_of_free_association [Ed: And see_the pattern]⠀⇛ The EPO violated the fundamental right of free association of its staff in 2014 by giving (former) president Benoit Battistelli the power to determine the detailed conditions relating to the staff committee elections. The Administrative Tribunal of the International Labour Organization (ILOAT) has ruled this in its judgment 4482, which was published after its 133d session late January. The decision, together with two other ILOAT judgments in which high moral damages were awarded, is yet again a display of the lack of legal protection and democracy at the EPO in the Battistelli era. Last year, the ILOAT had already ruled that Battistelli abused his power in July 2013 by restricting the rights of staff members to strike (case 4430), see also this blogpost. At the time the ILOAT ruled that Circular No. 347, regulating the restrictions, was unlawful. This time Circular No. 355 was quashed by the ILOAT, which contained implementing rules for a “social democracy” reform introduced by the Administrative Council in decision CA/D 2/14 on 28 March 2014. # § Software Patents⠀➾ # ⚓ $12,000_for_Atlantic_IP_Services_sub,_Speir Technologies,_prior_art⠀⇛ On January 28, 2022, Unified added 6 new PATROLL contests, with a $2,000 cash prize for each, seeking prior art on the list below.

It also affirmed refusals of the entire applications based on the applicant’s failure to disclaim “HEMP COMPANY” and its failure to amend the description of the mark to conform to the application drawing and the color claim of record.. In re Harbor Hemp Company LLC, Serial Nos. 88377702 and 88377730 (January 27, 2002) [not precedential] (Opinion by Judge Thomas Shaw). [...] Applicant did not submit evidence of FDCA approval, and so it was unlawful for applicant to introduce its goods into the marketplace at the time of its application filing date. [I believe that the drug Epidiolex is the only drug derived from marijuana that has been approved by the FDCA - ed. (FDA announcement here)]. Nevertheless, applicant argued that, at least for intent-to-use applications, registration should be allowed where use in any one state is illegal, since the trademark owner can avoid selling in states where it is illegal. The Board disagreed. # ⚓ Design_Systems_in_China_and_the_European_Union [Ed: Which institution is more corrupt? EUIPO or its Chinese counterpart?]⠀⇛ The design of a product can be protected by an intellectual property right through a registration before an intellectual property office. In this article, it will be compared the design systems of China and European Union. In general terms, the scope of protection of a design encompasses the appearance of the whole or a part of a product resulting from the features of, in particular, the lines, contours, colors, shape, pattern, texture and/or materials of the product itself and/or its ornamentation. [...] A Chinese patent design is valid for a maximum of 15 years from the filing date subject to the payment of annuity fees. The new Patent Law increases the term of design patents from 10 years to 15 years, which is a reflection of the preparation of China’s accession to the Hague Agreement, since the minimum protection period for designs is 15 years among the contracting states of the Hague Agreement. In the EU, a RCD is initially valid for 5 years from the filing date and can be renewed for 5‑year periods, up to a maximum of 25 years. However, the protection of an unregistered design only lasts 3 years from the date of its first public disclosure within the EU territory. # § Copyrights⠀➾ # ⚓ BREIN_Chases_Largest_Dutch_Pirate_IPTV_Supplier Around_The_World⠀⇛ Dutch anti-piracy group BREIN is leaving no stone unturned to hold the one-time largest pirate IPTV trader in the Netherlands to account.
