Today, another bully, who had defamed Richard Stallman for years, finally announced: “Now, nearly 5 years later, I’ve decided the timing is right for me to step back and for GNOME to start looking for its next leader.” That’s Mr. McGovern, joining the likes of Bully de Blanc and Nicholson, who helped him start the anti-FSF (via RMS) hate_campaign. They did this in Microsoft GitHub, so clearly enough they did not have freedom in mind (or_even inclusion). That happened just less than 11 months ago, so they’ve barely lasted a year. As I note in the video above, RMS is very active behind the scenes (he has been talking to us about Gemini lately; last_public_talk_this winter with full video here), whereas his haters gradually go away. They’ve rendered themselves irrelevant. More concrete news will hopefully follow soon. New Executive Director to be announced soon by the FSF*? “Our community is under attack; these supposedly well-meaning foundations get captured by our adversaries and actively work against our communities.”So who next to lead the GNOME Foundation? Did Neil receive a job offer from Microsoft? Probably not, but time will tell… Regardless, the GNOME Foundation is now without leadership (there’s no instant succession) and we start to see in this foundation much of what we saw in the Linux_Foundation. It’s captured by corporations which are hostile towards Free software and as recently as hours ago (noted above in the video, towards the end) we were reminded of “Linux Foundation” badge of environmentalism for Microsoft [1, 2, 3] because someone published “Microsoft,_Linux_Foundation, others_join_Carbon_Call“ (greenwash). Our community is under attack; these supposedly well-meaning foundations get captured by our adversaries and actively work against our communities. █ “Idiots can be defeated but they never admit it.” –Richard Stallman ______ * Damage was nevertheless done during/after the ‘coup’. Here’s_the_current_list of_FSF_staff, as of today: 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇FSF_end_of_2021⦈_ And compared to last_year (differences highlighted): 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇FSF_early-mid_2021⦈_ The FSF made the right decision though (almost_6,900_signatures were added to the RMS endorsement letter, signed in support of the FSF’s decision to bring back RMS).

No_Need_for_a_Diaspora_Away_From_JoinDiaspora,_as_the_Pod_Looks_Like_It’ll Survive_After_All⠀✐ Posted in Free/Libre_Software at 9:28 am by Dr. Roy Schestowitz Video_download_link | md5sum 0f2481707b0c14e5db0efe443bc0173c Looks Like JoinDiaspora Will be OK Creative Commons Attribution-No Derivative Works 4.0 http://techrights.org/videos/helping-joindiaspora-survive.webm Summary: There’s technical work/discussion and apparently advanced diplomacy/ negotiation underway to pass JoinDiaspora to new hands, giving this very important pod (over 316,000 registered users; the video erroneously says “316″) a new lease of life TO understand the choice of the name diaspora one needs to understand the roots and the motivation of the project. It was initially about people fleeing Facebook, which had become far too evil for a lot of people. Even more than a decade ago! Funds were raised to make Diaspora happen. Now it’s free for all of us to share! More than a decade later… we’re still here. “It was initially about people fleeing Facebook, which had become far too evil for a lot of people.”Last week I_wrote_about_the_JoinDiaspora_situation because it looked like JoinDiaspora was in serious trouble, with possibly just 18 days away from permanent shutdown. It takes 14 days to decide on succession in a sort of vote on whether to pass it to another “podadmin”. That’s according to what Lukas, the current “podadmin” (whom I am eternally grateful to!), has told me. Now that we’re 14 days away from the deadline I’m happy to quote Dennis Schubert as_saying: “Don’t worry about the March 1st timeline – even if our preparations are not done by then, everything will be fine. Please refrain from spamming Lukas, me, or anyone else. That doesn’t make things go any faster. Make yourself a hot chocolate or something and relax.” It seems like they’re working things out. Schubert_already_said_3_years_ago: “Happy to take over joindiaspora.com immediately – regardless of the hosting platform and the state it’s in – as well as covering all expenses from my personal account as a temporary solution until account migrations are ready for prime time so that joindiaspora users can distribute more evenly. Lukas, you know how to reach me.” “It’s not “just another pod”, it’s the “original” pod with lots of historic value and over 316,000 registered users.”They’re now in active discussions (probably of a technical and legal nature) and Schubert says: “I will write a comment here in this thread saying as much on Sunday, Feb. 20th.” That’s next weekend. The bottom line is, we’ve quite likely found a new “podadmin” (implicit assurance; quite a few people got involved), whom I trust based on his track record at Mozilla and elsewhere. As noted in the video above, we should fully support whoever takes over. Lukas is being a bit picky as he wishes to ensure the pod is left in responsible hands with long-term commitment. Let’s wait patiently for next Sunday. So much of my advocacy (and hundreds of thousands of posts from “Linux”/”Tux Machines”) did depend on this pod. It was where a lot of my posts originate from (including “tweets”). It’s not “just another pod”, it’s the “original” pod with lots of historic value and over_316,000_registered users. See some of the comments in the active thread; the pod means so much to so many people! 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇Yellow daffodils⦈ Diaspora is not a dying platform. The dying platforms are Social Control Media ‘bubbles’ such as Google+ — a bubble which itself resulted in Pluspora with 15,722_users_and_over_a_million comments. Let’s keep federating because if the main alternatives to that are centralised garbage (such as YouTube, TikTok, Twitter, Facebook, and Microsoft LinkedIn), then even a “lesser evil” (not self-hosting but federation) is worth defending. Here is what Schubert told me when JoinDiaspora had technical issues and Lukas was in Japan. █ 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇Happy_to_take_over_joindiaspora.com_immediately_-_regardless

When_It_Comes_to_Patents,_Lies_Have_Become_the_‘Norm’⠀✐ Posted in Deception, Europe, Patents, Site_News at 4:48 am by Dr. Roy Schestowitz Video_download_link | md5sum 6c78be70214a4dafd1ebb266f6d2b3c5 Reading News About Patents in 2022 Creative Commons Attribution-No Derivative Works 4.0 http://techrights.org/videos/patent-misinformation.webm Summary: In the above, which is a very long video, I wish to humbly and respectfully share my experiences which have been rather consistent this past year or two; due to the incredible amount of misinformation (objectively false statements) it’s emotionally-draining just looking through patent “news” (in Gulag Noise/Google News) along with “legal” analyses from so-called ‘law’ firms; even the patent-focused “blogs” or “news” sites are exceptionally dishonest, leading their more honest writers to fatigue and sometimes resignation, and that’s partly because of a financial conflict of interest (their site sponsors and/or the authors’ employers); they’ve managed to googlebomb the Web and maintain a false, fictional sense of reality around patents and patent systems/offices THE above video is almost 3 hours long. It might become part of a weekly routine. Until last year I had read news about patents every day; towards the end of the year it became a “once per week” thing because the level of noise became intolerably disruptive. In particular, the amount of “fake news” from Team UPC became quite overwhelming. As noted above at the start of the video, epo.org continues to be a premier source of “fake news” [1, 2]. It’s bolstered by yet more sources of misinformation, which feed a cycle of self-deception (echo_chamber). Typically, investigative journalists step in and break the cycle of lies; but such journalism barely exists anymore. Moreover, Gulag (Google) became a purveyor and spreader of misleading, self-serving “truthiness”. 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇Google_Goolag_or_gulag⦈_ Google News used to provide many adequate articles on the subjects searched for (or the news sought). Now, as in recent years (many_journalists_were_laid_off and_newsrooms_shut_down), it’s more like Gulag Noise due to neglect, malicious agenda (manipulation like Social Control Media gets more “engagement”), and it merits a term like gulagbombing (gaslighting the tenants with disinformation), reinforcing a highly twisted sense of what’s going on (Team UPC is a fine example of such manipulation). There’s no incentive for Google or Alphabet to tackle this issue as Google is among those benefiting from distortion of the patent regime, which begets more monopolies and privatisation (Google has already been embedded in the patent examination process). Long before covering EPO scandals I watched closely the debates on European software_patents, which basically resulted in a semi-triumph or temporary victory for software developers. Of course they opposed such patents; it’s very hard to find programmers who gleefully cheer for such a nuisance and a yoke; even proprietary software coders loathe such patents. “To demonstrate what’s going on I left my RSS reader to fill up for a week.”Times have changed. Journalism in the domain of patents is very rare nowadays. Publishers like Bloomberg actively pursue and then employ couriers of patent maximalists, who don’t bother with objective voices. This means that in so-called ‘news’ sites we find a truly awful signal-to-noise ratio, meriting nothing but rants, frustration-driven outbursts in editorial comments, and a lack of capacity to respond to the misinformation due to the very vast quantities of it. To demonstrate what’s going on I left my RSS reader to fill up for a week. In the video above I then walked through the RSS feeds (via the reader, QuiteRSS), echoing out loud what I’d otherwise put in writing, which can take a lot more time and be less gratifying because of the lack of tone. Two-fold issue can be observed here; first, Gulag’s neglect of its “monopoly” over news-finding (near to real time owing to its resources and financial might); then there’s the bunch of laws firms with their aggregators gaming Gulag and interjecting tons of lies, drowning out any form of signal (accurate information) with their self-serving noise. “I very well remember some truly good investigate journalism on the subject of patents…”Maybe I’ll do something like the above every weekend or two. Prior to that I just ended up linking to sites/articles/blogs that are false, spammy, intentionally misleading, and a combination of those things, in essence giving them traffic just to be able to respond/rebut. The problem used to be more constrained/limited to “tweets” back when sites like JUVE actually did journalism, not spam/PR for sponsors (they became webspam or a spamfarm in “directory” clothing). Nowadays the Social Control Media sites — LinkedIn included (many lawyers are active there, compared to Facebook and Twitter) — are just about as lousy as domains that used to promote themselves as legitimate news sources. The video above covers many examples and also reveals some of the ways I was getting my news on patents since around 2007 (intense focus on software patents back there), trying to sort out or separate the wheat from the chaff. I very well remember some truly good investigate journalism on the subject of patents back then; nowadays it’s a rarity and PR or press releases occupy those very same sites; many such sites perished completely (now offline). “The EPO’s management has been gaming key terms…”Searching ordinary Gulag Search (Google) for these topics would most likely result in spammy self- promotional rubbish parcelled as information. The EPO’s management has been gaming key terms (SEO which targets words like “Quality”) for years already, hoping to hide the views of EPO staff, replacing them with disinformation, sponsored by Benoît_Battistelli and António_Campinos at the EPO‘s expense. █ ⣿⡿⣋⣹⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⣍⣛⢿⣿

§ Desktop/Laptop⠀➾ # ⚓ 5_Major_Developments_in_Desktop_Linux_in_2022⠀⇛ Linux is an ever-evolving family of operating systems. Here are some of the desktop advancements you can expect to see in Linux in 2022. Linux is the dominant operating system on servers, but it’s much less well-known as a desktop operating system. Yet the Linux desktop has come a long way in the past decade, and the momentum isn’t slowing. Linux development happens out in the open, but unless you know where to look, it’s easy to miss. Here are several major developments happening simultaneously to keep your eyes on. o § Audiocasts/Shows⠀➾ # ⚓ Manjaro_21.2.0_GNOME_Edition_Quick_overview_#Shorts_– Invidious⠀⇛ A Quick overview of Manjaro 21.2.0 GNOME Edition. # ⚓ mintCast_378_–_Reaching_Enlightenment_–_mintCast⠀⇛ First up in the news, Mint 20.3 Una is released, Pipewire has a new release and Solus co-lead resigns In security, Ubuntu Kernel update fixes vulnerabilities and Ryzen Mobile CPU’s and Pluton Security In our Wanderings, Joe talks about the HPR New Year Show, Norbert watched a new series, Bill has been on the grind with cold temperatures, Nishant joined the Serenity OS team and Moss is back # ⚓ XeroLinux._Is_It_Just_About_The_Eyecandy?_–_Invidious⠀⇛ XeroLinux is an Arch-based Linux distro that focuses heavily on eyecandy and polish. XeroLinux comes in three different desktop editions: KDE Plasma, GNOME and Xfce. Today, I’m going to take a first look at their flagship edition (KDE). # ⚓ Stop_Praising_High_Linux_System_Uptime!_–_Invidious⠀⇛ Every so often I see people talk about how much uptime [their] linux system has and I have no idea why people praise this, a high system uptime isn’t something that should be praised in fact, you should be mocked for not updating your system for that long. o § Kernel Space⠀➾ # ⚓ Using_Device_Tree_Overlays,_example_on_BeagleBone_boards⠀⇛ The Device Tree language is a way to describe hardware that is present in a system and cannot be automatically detected. That’s the case of devices directly implemented on a System on a Chip, such as serial ports, Ethernet or Nand flash controllers. That’s also the case of devices connected to a number of buses, such as I2C and SPI, that do not provide mechanisms for dynamic enumeration and identification of devices. For a given CPU architecture (ARM, PowerPC, etc), such a description allows to have a unique kernel supporting many different systems with distinct Systems on a Chip. The compiled Device Tree (DTB: Device Tree Binary), passed to the kernel by the bootloader at boot time, lets the kernel know which SoC and devices to initialize. Therefore, when you create a new board, and want to use a standard GNU/ Linux distribution on it, all you have to do is create a new Device Tree describing your new hardware, compile it, and boot the distribution’s kernel with it. You don’t need to recompile that kernel, at least when it supports your SoC and the devices on your board. # ⚓ Intel_software-defined_silicon_to_debut_with_the_next version_of_Linux⠀⇛ Intel’s plans for software-defined silicon (SDSi) will begin to fall into place with the next version of the Linux kernel, it has emerged. The company has remained tight-lipped about the SDSi initiative, whereby customers will pay an additional fee to activate certain features built into their processors. Although Intel has acknowledged the existence of the scheme, it has so far offered no specifics as to which capabilities can be toggled on or off and which CPUs will be compatible. However, a message sent to the Linux Kernel Mailing List by a Red Hat developer has revealed Intel’s SDSi code will be incorporated into the Linux kernel “before the 5.18 merge window”, which commences at the end of March. The finalized version of Linux 5.18 is expected to land in May. # ⚓ AMD’s_Linux_tweaks_pave_the_way_for_USB_4_in_Ryzen_6000 laptops⠀⇛ AMD has made tweaks to USB 4 handling in Linux, which come on top of recent patches to ensure that USB 4 works with laptops powered by Ryzen 6000 mobile silicon. As you may recall, laptops with Ryzen 6000 APUs inside – otherwise known as ‘Rembrandt’ chips – are the first to support USB 4 (and therefore Thunderbolt 3, optionally) on the AMD front, with Team Red now pushing to get the software side ready for when these devices launch, and they should arrive imminently (the company has previously said Ryzen 6000 notebooks will be out at some point in February, or the first models should be, anyway). # § Graphics Stack⠀➾ # ⚓ NVIDIA_fix_up_a_Vulkan_problem_with_the_v510.54 driver_release⠀⇛ NVIDIA decided Linux gamers need a little love on Valentines Day so they put up a small driver release for you. In comparison to previous drivers, it’s not going to make any big headlines. There’s no big new features, no new Vulkan extensions or performance improvements. Instead, there’s quite an essential bug fix included. o § Benchmarks⠀➾ # ⚓ Linux_Snatches_Alder_Lake_Productivity_Crown_From_Windows 11_|_Tom’s_Hardware⠀⇛ The latest Kernel updates for Linux have brought some important performance optimizations for Intel Alder Lake CPU owners. When Intel’s 12th-Gen Core processors first launched in Q3 2021, they were better performers in Windows 11 (with its new scheduler) than in Linux. Now, thanks to Linux kernel improvements since Linux 5.16, the open source OS has retaken the lead with Intel’s first desktop hybrid architecture processors. Linux- centric site Phoronix ran a bevy of benchmarks looking at browsing, coding, rendering, encoding, and de/compression. o § Applications⠀➾ # ⚓ The_8_Best_Apps_to_Transfer_Files_Between_Android_and Linux⠀⇛ Need to share a file from your Linux desktop to Android, or vice versa? Check out these eight apps that let you transfer your files effortlessly. As an Android user who runs Linux on their desktop, you have several options for transferring files between your Android phone and Linux computer. Using a USB cable or Bluetooth are two such methods. However, while these methods can help you transfer files between your devices, they tend to be inefficient when you need to transfer files frequently. File transfer apps, on the other hand, are a much better option, as they facilitate quick and efficient file transfers between devices. Here are the best apps to transfer files between Android and Linux that you must check out. # ⚓ Best_PDF_Editors_to_Edit_PDF_Documents_in_Linux⠀⇛ The PDF file format is one of the most widely used document formats that is used to attach, transfer and download digital files thanks to its ease of use, portability, and ability to preserve all elements of a file. You can seamlessly view a PDF document across multiple devices without visual alteration of its contents. Occasionally, you might want to modify your PDF and maybe add text, images, fill forms, append a digital signature, and so on. In this guide, we have put together a list of PDF editors (both free and proprietary) that you can leverage to modify your PDF documents. # ⚓ 10_Lightest_Linux_Apps_and_Programs_to_Speed_Up_an_Old_PC⠀⇛ You could tune up a car by yanking out the engine and putting in a new one, but that’s pretty drastic. Sometimes, so is switching your Linux distribution. Sure, that’s a great way to breathe life into an aging machine—but it’s also a lot of work! Even if you go through that effort, it doesn’t matter if you’re using heavy applications. So if you want to lighten the load on your Linux-powered machine, these are the programs you want to run. # ⚓ Announcing_Istio_1.12.3⠀⇛ This release contains bug fixes to improve robustness. This release note describes what’s different between Istio 1.12.2 and Istio 1.12.3. o § Instructionals/Technical⠀➾ # ⚓ How_to_Use_the_dd_Command_in_Linux⠀⇛ dd is one of the most important commands in Linux, mostly used in backing up hard disks and partitions. When utilized correctly, dd can be a powerful tool for writing data from one partition to another and performing different tasks with files. Here we show you how to put the dd command to good use. # ⚓ How_to_Set_Up_WordPress_Multisite_with_OpenLiteSpeed_on Ubuntu_20.04_–_RoseHosting⠀⇛ WordPress is a free, open-source, and one of the best content management systems around the world. It is based on PHP and uses MySQL/MariaDB as a database backend. It provides a simple and easier way to create a simple to advanced blog or website.

In this guide, we will show you how to install WordPress multisite with OpenLiteSpeed on Ubuntu 20.04 server. A multisite network is a group of sites sharing the same WordPress installation and could also have the same plugins and themes. # ⚓ How_To_Change_Passwords_in_Linux_|_Tom’s_Hardware⠀⇛ Passwords are one of the most important aspects of computing. They keep our bank accounts, user profiles and computers safe (as long as we don’t reuse passwords). Just to log into our computers, most of us need a password and, for Linux, this is even more important. Managing passwords via the terminal is relatively simple. Users can change their own passwords and users belonging to the sudo (super user) account can administrate the passwords of other users. In this how-to we’ll learn the basics of passwd, a command designed to manage passwords. We will also learn a few advanced arguments for this command, arguments which will enhance its use and make our lives easier. These commands will work on most Linux machines. Our test PC ran Kubuntu 21.10 but you can also run through this how-to on a Raspberry Pi. All of the how-to is performed via the Terminal. # ⚓ How_to_Install_UVdesk_Helpdesk_on_Ubuntu_–_VITUX⠀⇛ UVdesk is an open-source helpdesk platform. It is designed to provide a convenient web-based helpdesk for companies that can be accessed from anywhere in the world.

The user interface is very easy to use, as well as being highly customizable by way of CSS or JavaScript, depending on what you would like to do. # ⚓ How_to_Customize_the_Orange_Dots_in_the_Dock_of_Ubuntu 20.04_/_22.04_|_UbuntuHandbook⠀⇛ Ubuntu by default shows orange dots under app icons in the dock panel, indicate the apps have running windows. They are called ‘running dots‘. And, Ubuntu provides hidden settings to change the style as well as colors if you don’t like the default look and feel. # ⚓ How_to_Build_a_Continuous_Delivery/Deployment_Pipeline Using_Jenkins.⠀⇛ In this post, you will learn how to build a Continuous Delivery using Jenkins # ⚓ How_To_Install_Kimai_web-based_time_tracking_application_in Linux⠀⇛ Kimai is a Free Time-Tracking App (open-source), With Kimai, the boring process of feeding Excel spreadsheets with your working hours is not only simplified, it also offers dozens of other exciting features that you don’t even know you’re missing so far! Kimai does not have to run while recording, you can even quit your browser. Your time is still recording until you stop it from any web browser that has access to your installation. It is designed to hold lots of users, but you can also use it for a single user if you want to. # ⚓ How_to_install_RStudio_on_a_Chromebook⠀⇛ Today we are looking at how to install RStudio 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. This tutorial will only work on Chromebooks with an Intel or AMD CPU (with Linux Apps Support) and not those with an ARM64 architecture CPU. # ⚓ How_to_install_OnlyOffice_on_Zorin_OS_16_–_Invidious⠀⇛ # ⚓ How_to_deploy_and_test_the_new_release_of_ONLYOFFICE Document_Server_|_TechRepublic⠀⇛ ONLYOFFICE is one of many options for those looking to host their own alternative to Google Workspaces. Recently ONLYOFFICE unleashed v7 of its platform, which includes exciting new features like a built- in form builder. Along with other features such as Projects, CRM, Mail, Contacts and Documents, ONLYOFFICE could be a perfect solution for those looking to bring such a tool in-house. # ⚓ How_to_Use_xargs_to_Process_Piped_Arguments_in_Linux⠀⇛ If you try to pipe the output from one Linux command into another, you may run into errors where the command fails because its argument list is too long. Fortunately, there’s a command on Linux systems that properly formats arguments to commands. It’s called xargs and here’s how to use it. # ⚓ Install/Enable_Configure_UFW_Firewall_on_Ubuntu_22.04_– LinuxCapable⠀⇛ One of the keystones of any operating system is a properly configured firewall for complete system security. Ubuntu uses IP tables; however, most users will use software that works as a front end with UFW (Uncomplicated Firewall). Some of the great benefits of UFW are its simplicity, user-friendly and easy-to-use command line, making it great for beginners in Linux to the most advanced power users. In the following tutorial, you will learn to install and set up UFW Firewall on Ubuntu 22.04 LTS Jammy Jellyfish desktop or server. # ⚓ Install_MKVToolNix_65.0.0_On_Ubuntu_/AlmaLinux_&_Fedora_| Tips_On_UNIX⠀⇛ MKVToolNix is an open-source software to create, alter and inspect Matroska files. MKVToolNix is available to end-users as a graphical and command line. MKVToolNix recently released a new version 65.0.0 and users are recommended to upgrade to this version, due to bug fixes and new features added to this release. This tutorial will be helpful for beginners to download and install MKVToolNix 65.0.0 on Ubuntu 20.04 LTS, Ubuntu 21.10, AlmaLinux 8, and Fedora 35. # ⚓ Detecting_Log4Shell_with_Wazuh⠀⇛ This time, you will learn about Detecting Log4Shell with Wazuh The Apache Log4J is one of the most common logging libraries in Java, mainly used for error messages. It is part of several high valued applications including iCloud, Twitter, and Minecraft amongst others. Recently, a zero-day vulnerability dubbed Log4Shell with CVE CVE-2021-44228 was detected in Apache’s Log4J 2 that allows malicious actors to launch Remote Code Execution (RCE) attacks. This means that an assailant can remotely send commands to a server running vulnerable applications. The affected Apache Log4j 2 versions are 2.0-beta9 to 2.15. As a matter of fact, version 2.15.0 which was the initial fix for the vulnerability was later discovered to still be vulnerable. So it is recommended to update to version 2.16.0 which disables JNDI and completely removes %m{lookups}. # ⚓ Linux_CMP_Command_Explained⠀⇛ The cmp command in Linux/UNIX compares two files byte by byte, allowing you to determine if they are identical or not. If a difference is detected, cmp displays the location of the first mismatch on the screen, if no difference is found, cmp displays the files are identical. cmp shows no message and basically returns the brief assuming the files analyzed are identical. A lot of options are available for the cmp command to be paired with to display different output, these options are explained below. Also, I am going to show you the practical uses of cmp command. # ⚓ Flatpak_on_Linux:_What_It_Is_and_How_to_Install_Apps_with It⠀⇛ Here we will learn what is Flatpak, how to install Flatpak on Linux, and how to use the Flatpak command-line user interface to install, remove, and update Flatpak applications. # ⚓ Convert_image_in_.png_format_to_.webp_on_Ubuntu_and_Ubuntu based_distributions⠀⇛ The webp image format has been around for quite a few years, but I only recently found out about it. The Webp image format greatly reduces the file size without losing any quality over formats such as .gif, .png and jpeg. Gimp on Linux already has this function to export as webp, but you can also install the cwebp package in Ubuntu or Ubuntu based distributions to convert images to the webp format using the terminal. With the basic command for converting one image below, you could create a bash script to take a folder of .png images or mixed images and convert these .webp format. # ⚓ Let’s_Encrypt_with_GnuPG_easy_100%⠀⇛ Public and private keys GnuPG each have a specific role when encrypting and decrypting documents. A public key may be thought of as an open safe. When a correspondent encrypts a document using a public key, that document is in the safe, the safe shut, and the combination lock spun several times. The corresponding private key is the combination that can reopen the safe and retrieve the document. In other words, only the person who holds the private key can recover a document encrypted using the associated public key. The procedure for encrypting and decrypting documents is straightforward with this mental model. If you want to encrypt a message to Alice, you encrypt it using Alice’s public key, and she decrypts it with her private key. Likewise, if you want to send a message, she encrypts it using your public key, and you decrypt it with your key. To encrypt a document, the option –encrypt is used. It would be best if you had the public keys of the intended recipients. The software expects the document’s name to encrypt as input or, if omitted, on standard input. The encrypted result is placed on standard output or specified using the option –output. The document will be compressed for additional security in addition to encrypting it. # ⚓ Traefik_for_Docker_Containers_on_Ubuntu⠀⇛ This post is about Traefik for Docker Containers. o § Games⠀➾ # ⚓ GOG_puts_up_a_We_Love_Games_Sale_with_lots_of_good_deals_| GamingOnLinux⠀⇛ Prefer GOG over other stores for their DRM-free collection? It’s Valentines Day and of course there’s a sale. The We Love Games Sale is live until Monday, February 21st at 2 pm UTC. This sale features a number of big hitters, new releases and plenty of indie gems to look out for. # ⚓ Building_a_Retro_Linux_Gaming_Computer_–_Part_12:_In Tremendous_Pain_|_GamingOnLinux⠀⇛ In 1998 developer Raven Software acquired the rights to Soldier of Fortune to make a video game inspired by the mercenary magazine of the same name. The plan was to make a realistic tactical shooter, with consultant John Mullins brought in to add both his insights and likeness to the project. The final result he described as “emblematic” of the real world experience, which is a generous way of putting it. Where the controversy laid was in the game’s violence. Soldier of Fortune was the first game to feature the GHOUL system, allowing for the depiction of damage to specific parts of the body, with your enemies reacting in graphic over the top ways. More pacific players might opt to instead just shoot the weapon from their hands, which is also made possible by GHOUL, but with your mission objectives often tied to eliminating all opponents on a map, such mercies are made just a block to your progress. A more salient discussion could have been had on the plot of Soldier of Fortune, steeped as it is in the doctrines of western military interventionism. It is hard to take a detached view of your actions in the game when they are taking place within the context of what were then contemporary conflicts. No matter where you stand on these issues, I think we can all agree that the cutscene where Mullins deferentially walks in on Saddam Hussein is more than a little surreal today. # ⚓ Check_out_Rise_of_the_Third_Power_if_you_love_JRPG_styled games_|_GamingOnLinux⠀⇛ Rise of the Third Power is a brand new release from Stegosoft Games and DANGEN Entertainment, the same team who previously released the popular Ara Fell: Enhanced Edition. This was first shown off back in 2017, a throwback to the SNES era of RPGs but of course built for modern audiences with plenty of up to date convenience features thrown in. That, plus a mix of designs inspired by JRPGs and more western elements too. In the game you build up a party of up to eight unique characters, with each having their own background story, ambitions, and personalities, as they embark upon a suicide mission to prevent a war and topple the Arkadyan emperor. A blend of humour, drama and tragedy await you in a 35+ hour story- focused quest as they navigate the treacherous world of Rin. # ⚓ Children_of_Morta_gets_online_co-op_in_the_Fellowship Sanctuary_update_|_GamingOnLinux⠀⇛ Children of Morta is easily one of the best looking pixel-art games around, and the gameplay is pretty awesome too. Now you can team up with a friend as the online co-op update is out. “Children of Morta is an action RPG with a rogue- lite approach to character development, where you don’t play a single character – but a whole, extraordinary family of heroes. Hack’n’slash through hordes of enemies in procedurally generated dungeons, caves and lands and lead the family of Bergsons, with all their flaws and virtues, against the forthcoming Corruption.” o § Desktop Environments/WMs⠀➾ # § K Desktop Environment/KDE SC/Qt⠀➾ # ⚓ Kile:_An_Interactive_Cross-Platform_LaTeX_Editor_by KDE⠀⇛ You can use a TeX/LaTeX editor for a variety of documents. Not just limited to scientific research, you can also add your code, start writing a book (academic/creative), or draft articles. An interactive solution with the option for preview, and several features, should come in handy if you regularly work with LaTeX documents. Kile is one such option by KDE, available for Linux and other platforms. In fact, it is one of the best LaTeX editors available for Linux, which we decided to highlight separately. # ⚓ You_Can_Now_Install_KDE_Plasma_5.24_LTS_on_Kubuntu 21.10,_Here’s_How⠀⇛ Released in October 2021, Kubuntu 21.10 (Impish Indri) ships with KDE Plasma 5.22.5 as the default desktop environment. But, thanks to the Kubuntu Backports PPA effort, users were able to quickly update to the KDE Plasma 5.23 “25th Anniversary Edition” and now they can update to the latest release, KDE Plasma 5.24. The Kubuntu team recently announced that the Plasma 5.24 packages are now available in the Kubuntu Backports PPA repository, alongside the KDE Frameworks 5.91 and KDE Gear 21.12.2 software suites, all compiled against the Qt 5.15.2 application framework. # § GNOME Desktop/GTK⠀➾ # ⚓ Modernizing_GTK’s_macOS_backend_(again)_–_Zen_and_the Art_of_GNOME⠀⇛ Since the early days of working on the macOS backend for GTK 4 I knew eventually we’d have to follow suit with what the major browsers were doing in terms of drawing efficiency. Using OpenGL was (while deprecated, certainly not going anywhere) fine from a performance standpoint of rendering. But it did have a few drawbacks. In particular, OpenGL (and Metal afaik) layers don’t have ways to damage specific regions of the GPU rendering. That means as we’d flip between front and back buffers, the compositor will re-composite the whole window. That’s rather expensive for areas that didn’t change, even when using a “scissor rect”. If you’re willing to go through the effort of using IOSurface, there does exist another possibility. So this past week I read up on the APIs for CALayer and IOSurface and began strapping things together. As a life-long Linux user, I must say I’m not very impressed with the macOS experience as a user or application author, but hey, it’s a thing, and I guess it matters. # ⚓ Georges_Basile_Stavracas_Neto:_OBS_Studio_27.2_on Flathub,_get_it_while_it’s_hot!⠀⇛ Today, OBS Studio published its 27.2 release. With this release, besides the always good to have bugfixes and improvements, there’s one change in particular that makes me super excited: this is the first release officially published to Flathub! Flathub joins OBS Studio’s Ubuntu PPA in the list of official builds. On Ubuntu, both can be installed and used without any major annoyance, since Flatpak can easily be installed there – though it would be great if Flatpak was distributed by default on Ubuntu, but oh well, such is life. For other Linux distributions, especially the ones not based on Debian, the Flathub package is probably the easiest one to install, and certainly the most complete. # ⚓ Neil_McGovern:_Handing_over⠀⇛ In 2017, I was attending FOSDEM when GNOME announced that I was to become the new Executive Director of the Foundation. Now, nearly 5 years later, I’ve decided the timing is right for me to step back and for GNOME to start looking for its next leader. I’ve been working closely with Rob and the rest of the board to ensure that there’s an extended and smooth transition, and that GNOME can continue to go from strength to strength. GNOME has changed a lot in the last 5 years, and a lot has happened in that time. As a Foundation, we’ve gone from a small team of 3, to employing people to work on marketing, investment in technical frameworks, conference organisation and much more beyond. We’ve become the default desktop on all major Linux distributions. We’ve launched Flathub to help connect application developers directly to their users. We’ve dealt with patent suits, trademarks, and bylaw changes. We’ve moved our entire development platform to GitLab. We released 10 new GNOME releases, GTK 4 and GNOME 40. We’ve reset our relationships with external community partners and forged our way towards that future we all dream of – where everyone is empowered by technology they can trust. o § Distributions⠀➾ # § New Releases⠀➾ # ⚓ KaOS_2022.02⠀⇛ With the release of Plasma 5.24, a first for KaOS can be announced. Wayland on Plasma is in such a good shape that it now can be the default session for KaOS. For Virtualbox, this means some intervention is needed for auto-resize, upstream does not support this yet for a Wayland session, so you will need to set the desired screen resolution in Systemsettings. When you choose to use non- free Nvidia during the boot-up of the Live session, then Wayland won’t be used, for Nvidia, it is still better to use an X session. [...] Other news regarding Plasma 5.24 includes a new Configure Display Settings item. This lets you adjust your screens’ resolution, orientation, scaling, and position relative to other monitors. Desktop Panels are now easier to move around and stick to any edge you want, as you can now drag them from anywhere on their toolbar while in Edit Mode. To make critically important Plasma notifications stand out, they now come with an orange strip on the side to visually distinguish them from less urgent messages. The Task Manager’s context menus have been clarified and simplified. The Add a keyboard layout dialog has been redesigned for simplicity and ease of use. And the Cover Flip and Flip Switch effects are back, you can find them in the System Settings Window Management > Task Switcher page. For the other KDE parts, the latest Frameworks (5.91.0) and KDE Gear (21.12.2) are included. All built on Qt 5.15.2+. # ⚓ KaOS_Linux_2022.02_Is_Out_with_KDE_Plasma_5.24,_Makes Plasma_Wayland_Default_Session⠀⇛ KaOS Linux 2022.02 comes a little over a month after KaOS Linux’s first release in 2022 and ships with the recently released KDE Plasma 5.24 LTS desktop environment, which is accompanied by the latest and greatest KDE Frameworks 5.91 and KDE Gear 21.12.2 software suites, as well as the brand-new Kalendar 1.0 app. With this release, KaOS Linux switches to Plasma Wayland as the default session for new installations. As you can imagine, this big move makes some changes in the distribution, such as the fact that the default media player, SMPlayer, has been replaced by Haruna as it supports Wayland. # ⚓ Kali_Linux_2022.1_Released_with_New_“Everything” Flavor,_New_Tools,_and_a_Visual_Refresh⠀⇛ Coming two months after Kali Linux 2021.4, the Kali Linux 2022.1 release is here with a visual refresh as the development team updated the desktop, boot splash, and login backgrounds, along with a refreshed installer theme and more consistent boot menu options to make the ethical hacking distro look more modern. Another major change in Kali Linux 2022.1 is the availability of a new ISO flavor called “Everything”, which apparently includes a complete Kali Linux environment with all the tools you’ll ever need for offline use. However, this image is huge in size (about 11GB) and it’s only offered as a torrent download. # ⚓ Kali_Linux_2022.1_Release_(Visual_Updates,_Kali Everything_ISOs,_Legacy_SSH)⠀⇛ Today we are pushing out the first Kali Linux release of the new year with Kali Linux 2022.1, and just in time for Valentine’s Day! This release brings various visual updates and tweaks to existing features, and is ready to be downloaded or upgraded if you have an existing Kali Linux installation. # § Debian Family⠀➾ # ⚓ Got_to_boot_a_RPi_Zero_2_W_with_Debian⠀⇛ About a month ago, I got tired of waiting for the newest member of the Raspberry product lineup to be sold in Mexico, and I bought it from a Chinese reseller through a big online shopping platform. I paid quite a bit of premium (~US$85 instead of the advertised US$15), and got it delivered ten days later… # ⚓ DSA-2019:_Debian_Security_Advisory:_Lovestruck Leaders⠀⇛ Clients and friends have been asking a very similar question recently: what do the scandals in Debian and other free software organizations mean for me, my computers, my servers, my business? [....] Many people perceive social engineering as an attempt to gain access to confidential information, for example, successfully impersonating the queen to obtain medical records. Yet social engineering attacks go much further. Sophisticated attackers encourage their targets to break rules in the hope that the shared knowledge of these crimes will give the attacker an opportunity to blackmail the target. Edward Snowden revealed an unsophisticated plot to entrap a Saudi banker in Geneva by orchestrating a drink driving violation. Many of the attackers have a long-term view. They start by testing small rule violations and gradually lead their target deeper and deeper into the hot water. [...] Once again, we need to come back to the question that started this blog: what does it mean for the user? These social engineering attacks under the guise of diversity may not compromise any of the archive keys or add new backdoors into the code. On the other hand, when ordinary volunteers see these rorts they may lose motivation. Fixes for security bugs, like everything else in Debian, depend on the motivation of volunteers to fix them promptly. A volunteer who was treated rudely at DebConf may simply leave a bug open for an extra week. High-impact projects that never finish: see the example of FreedomBox, which still hasn’t made an official release after more than 12 years. Social engineering can play a role in all of these phenomena. # § Canonical/Ubuntu Family⠀➾ # ⚓ Slimbook_&_Kubuntu_18.04_–_Combat_report_14⠀⇛ My Slimbook brings all the nerds to the yard, and they’re like. Indeed. The laptop works well. Kubuntu 18.04 proudly holds its ground. The experience is slick and modern. I often compare the looks in Plasma 5.12 to the new crop, and there’s something rather professional and yet charming in the more classic layout of this older LTS. The new releases have a bit more crayony, flatter feel, and while it isn’t bad or ugly, it feels slightly less expensive, so to speak. I am quite pleased. The device is fast and does every task well. There are some questions marks regarding the battery, but I don’t have more data on that just yet. The system performance remains excellent, and nothing has really changed in the past three odd years. Every reboot, the save-session feature of Plasma makes me grin. Yes, there are annoying bugs, mostly inside applications, and stubborn won’t-fix issues in the desktop itself, which are only fixed in newer versions of Plasma. But all in all, even with an odd crash and some silly errors, the general feel remains good. Thinking about it, with Windows 11 looming over the horizon, I might have to seriously rethink my day-to- day choices and go full-KDE 24/7 (except gaming, of course). So far, the Slimbook Pro2 and its Kubuntu operating system prove that this can be done with joy, elegance and efficiency. We’re done. Until the next report. o § Devices/Embedded⠀➾ # ⚓ NanoPi_router_board_updated_with_8GB_eMMC_and_a_metal case⠀⇛ FriendlyElec launched a $48 “NanoPi R2C Plus” router, an case-only variant of the RK3328-based NanoPi R2C SBC that adds 8GB eMMC, among other minor changes. Meanwhile, there is now a $9 metal case for the similar Orange Pi R1 Plus LTS SBC. In the NanoPi R2C blurb in our recent catalog of 136 Linux hacker boards, we mentioned that an eMMC equipped NanoPi R2C Plus was in the works. As reported by CNXSoft, the Plus model is now shipping for $48, but only in a version with a metal enclosure. CNXSoft also reported that Shenzhen Xunlong’s almost identical Orange Pi R1 Plus LTS router SBC, which similarly combines a Rockchip RK3328 and dual GbE ports, is now available with its own metal enclosure for $36 (see farther below.) # ⚓ Edge_AI_box_with_PoE_and_GMSL_taps_new_64GB_RAM_Jetson_AGX Xavier⠀⇛ Vecow’s “EAC-3000” edge AI system runs Linux on a new 64GB RAM version of the 32-TOPS Jetson AGX Xavier and supplies GbE, 4x GbE with PoE+, 4x USB 3.0, 2x COM, 2x CAN, 2x DDI, 3x M.2, and 8x Fakra- Z links for GMSL cameras. Vecow announced a rugged embedded computer that supports a new Jetson AGX Xavier 64GB version of Nvidia’s high-end AGX Xavier module that doubles the LPDDR4x RAM to 64GB. The EAC-3000 is designed for in-vehicle computing, robotic control, medical imaging, public security, smart factory, AMR/AGV, and AIoT/Industry 4.0 applications. # § Mobile Systems/Mobile Applications⠀➾ # ⚓ What’s_the_difference_between_Android_12L_and_Android 13,_and_when_will_my_phone_get_it?⠀⇛ # ⚓ Android_13:_The_first_developer_preview_has_arrived_| TechRepublic⠀⇛ # ⚓ POCO_X4_5G:_Global_version_of_Xiaomi’s_upcoming_mid- range_smartphone_surfaces_with_Android_11,_a_Snapdragon 695_and_6_GB_of_RAM_–_NotebookCheck.net_News⠀⇛ # ⚓ How_To_Update_Google_Play_Store_On_An_Android Device⠀⇛ # ⚓ Got_an_Old_Android_Phone?_Repurpose_It_With_These_9 Creative_Hacks_–_CNET⠀⇛ # ⚓ Niagara_Launcher_Is_the_Best_Android_Launcher_for_Big Phones⠀⇛ # ⚓ Samsung’s_new_Android_tablets_are_so_popular_that_it had_to_halt_preorders_|_Ars_Technica⠀⇛ # ⚓ Samsung_Galaxy_S22_vs._Google_Pixel_6:_Which_Android Flagship_Should_You_Buy?_|_PCMag⠀⇛ # ⚓ Android_13_looks_set_to_bring_substantial improvements_to_screen_savers⠀⇛ # ⚓ Android_13_lets_you_run_Windows_11_on_your_smartphone –_Gizchina.com⠀⇛ # ⚓ android:_Android_12_guide:_How_to_turn_off_camera_and microphone_access_in_one_tap_from_all_apps⠀⇛ # ⚓ Android_12_Reaches_Samsung’s_Galaxy_Z_Fold_2_In_The US⠀⇛ # ⚓ LG_Wing_5G_delivers_a_unique_swiveling_Android experience_at_$280_in_Woot_refurb_sale_–_9to5Toys⠀⇛ # ⚓ Nokia’s_latest_budget_Android_phone_has_a_50MP camera,_three-day_battery_life_|_Android_Central⠀⇛ o § Free, Libre, and Open Source Software⠀➾ # § SaaS/Back End/Databases⠀➾ # ⚓ PostgreSQL:_pgAdmin_4_v6.5_Released⠀⇛ The pgAdmin Development Team is pleased to announce pgAdmin 4 version 6.5. This release of pgAdmin 4 includes 24 bug fixes and new features. For more details please see the release notes. pgAdmin is the leading Open Source graphical management tool for PostgreSQL. For more information, please see the website. # ⚓ PostgreSQL:_Ora2Pg_v23.1_released⠀⇛ Version 23.1 of Ora2Pg, a free and reliable tool used to migrate an Oracle database to PostgreSQL, has been officially released and is publicly available for download. This release fix several issues reported since past four months and adds some new major features and improvements. # § Programming/Development⠀➾ # ⚓ Introducing_Buildkite_integration_–_Octopus_Deploy⠀⇛ Octopus Deploy now integrates with Buildkite. Our new Buildkite plugins will allow your build agents to create and deploy releases, push build information, and run runbooks as part of a pipeline. This post shows you how to use the Buildkite plugins to perform various operations with Octopus Deploy as part of a pipeline in Buildkite. [...] The integration provided through our new Buildkite plugins represents our initial design and release. We plan to build additional plugins and eliminate the dependency on the Octopus CLI by providing integration through Bash scripts. If you’re an existing Octopus Deploy customer, check out Buildkite as part of your build pipeline. If you’re an existing Buildkite customer, check out Octopus Deploy for deployments. And if you haven’t tried either product, consider them both as part of your CI/CD pipeline. # § Rust⠀➾ # ⚓ Crates.io_Index_Snapshot_Branches_Moving_|_Rust Blog⠀⇛ Every so often, the crates.io index’s Git history is squashed into one commit to minimize the history Cargo needs to download. When the index is squashed, we save snapshots to preserve the history of crate publishes. Currently, those snapshots are stored as branches in the main index Git repository. Those branches are using server resources though, as the server still has to consider their contents whenever Cargo asks for the master branch. We will be deleting the snapshot branches from this repository to ensure that all objects referenced in the master branch will only be compressed against other objects in the master branch, ensuring that the current clone behavior will be much more efficient on the server side. * § Leftovers⠀➾ o § Hardware⠀➾ # ⚓ A_Solari_Mechanical_Digital_Clock_Hack_With_A_Little_Extra |_Hackaday⠀⇛ [Alfredo Cortellini] was perusing an antique shop in Bologna, and came across a nice example of a late 1950s timepiece, in the shape of a Solari Cifra 5 slave clock, but as the shop owner warned, it could never tell the time by itself. That sounded like a challenge, and the resulting hack is a nice, respectful tweak of the internals to bring it into the modern era. Since the clock requires a single pulse-per-minute in order to track time, the simplest track often followed is to open the back, set the correct time manually by poking the appropriate levers, and then let an external circuit take over clocking it. [Alfredo] wanted autonomy, and came up with a solution to make the thing fully adjust itself automatically. Electronics-wise, initial prototyping was performed with a Nucleo 32 dev board and a pile of modules, before moving to a custom PCB designed in Altium Designer. An STM32G031 runs the show, with a few push buttons and a SSD1306 OLED display forming the UI. # ⚓ This_Minibike_Will_Land_You_In_Hot_Water_|_Hackaday⠀⇛ The minibike is an American phenomenon which fascinates those of us from countries in which such contraptions are illegal on the road; they seem to deliver bucketloads of low-octane fun in which we are unable to participate. [HowToLou] has one, and as it’s something for use in the Great Outdoors it naturally requires some means of fixing a brew. His solution to the need for a mug of boiling water in out-of-the-way places? A gravity-fed heat exchanger for the exhaust pipe, fed from a reservoir made using an upturned bottle. [...] It may not be the most practical of water heaters, but it’s certainly a bit of fun even if it might not work with all the minibikes we’ve covered. # ⚓ Fail_Of_The_Week:_A_Bigger_Hacksaw_Isn’t_A_Better_Hacksaw_| Hackaday⠀⇛ If we’re being honest, the main reason to buy a power tool is to avoid the pain of using one’s muscles. Oh sure, we dress it up with claims that a power tool will make us more productive, or give better results, but more often than not it’s the memory of how your forearm feels after a day of twisting a screwdriver that makes you buy a cordless driver. It appears that [Artisan Makes] has a high tolerance for pain, seeing how the main prep tool in his metal shop is a plain old hacksaw. So in an effort to speed up his stock prep, he turned not to a bandsaw or cutoff saw, but instead built the world’s silliest hacksaw. It’s the metalworking equivalent of the two-man bucksaws that lumberjacks used to fell trees before chainsaws came along, and at a meter and half in length, it’s about the size of one too. Modifying the frame of his trusty hacksaw was easy — he just popped the end pieces off and attached them to an extra-long piece of tube stock. Finding a 1.5-meter hacksaw blade was the main challenge; not exactly a big-box store item, that. So a section of metal-cutting bandsaw blade was modified to fit the frame, and it was off to the races. o § Integrity/Availability⠀➾ # § Proprietary⠀➾ # § Pseudo-Open Source⠀➾ # § Privatisation/Privateering⠀➾ # § Linux Foundation⠀➾ # ⚓ Microsoft,_Linux_Foundation,_others join_Carbon_Call [Ed: It is worth noting that the so-called ‘Linux’ Foundation continues shilling Microsoft with greenwashing; this foundation’s_efforts_with_Microsoft have_actively_hurt_Linux,_the brand]⠀⇛ The ClimateWorks Foundation has announced the Carbon Call, an effort by twenty organizations including businesses like Microsoft, the Linux Foundation and KPMG. The goal is to develop reliable and accurate carbon emissions accounting, something the sponsoring organization and signatories agree is lacking presently. # § Security⠀➾ # ⚓ Security_updates_for_Monday_[LWN.net]⠀⇛ Security updates have been issued by Debian (debian-edu-config, expat, minetest, pgbouncer, python2.7, samba, thunderbird, and varnish), Fedora (dotnet-build-reference-packages, dotnet3.1, dotnet6.0, hostapd, libdxfrw, librecad, mingw-expat, mingw- gdk-pixbuf, php-twig2, php-twig3, rust- afterburn, webkit2gtk3, and xstream), Mageia (bluez, firefox, libarchive, php-adodb, thunderbird, and webkit2), openSUSE (ghostscript, openexr, permissions, SDL2, and wireshark), Red Hat (firefox), Slackware (mariadb), and SUSE (busybox, ghostscript, openexr, permissions, SDL2, and wireshark). # ⚓ Linux_tops_Google’s_charts_for_fixing_bugs_the fastest_•_The_Register⠀⇛ The bug hunters at Google’s Project Zero team have released their latest time-to-fix data and Linux is smashing the opposition. Between 2019 and 2021 open-source developers fixed Linux issues in an average of 25 days, compared to 83 for Microsoft and Oracle pulling last place at 109 days, albeit from a very low number of cases. Furthermore Linux is showing consistent improvement in response times, from 32 days in 2019 to just 15 last year, and that improvement is being mirrored (mostly) across the industry. “In 2021, vendors took an average of 52 days to fix security vulnerabilities reported from Project Zero,” said the team’s Ryan Schoen in the report. “This is a significant acceleration from an average of about 80 days three years ago.” When it comes to mobile fixes Apple leads the telecoms duopoly, sorting out issues in an average of 70 days, compared to Android’s 72. # ⚓ Does_Linux_need_antivirus?⠀⇛ Wondering if Linux users can take operating system security for granted and not worry about using anti-virus? Let’s look at the risks and what you can use to protect yourself when you’re running this popular open source OS and alternative to Windows 11. Linux malware has been gradually increasing over the years, with a 35% growth in Linux malware in 2021 identified by endpoint protection vendor Crowdstrike, largely affecting Internet-of-Things devices. But, assuming your day-to-day security practices are good and your OS is up- to-date, your Linux desktop doesn’t have a particularly great need of antivirus software. OS security updates promptly address new threats, to the point where the official position of Canonical, maker of Ubuntu Linux is that “Linux viruses are so rare that you don’t really need to worry about them at the moment. # ⚓ Adobe_Releases_Security_Updates_for_Commerce and_Magento_Open_Source_|_CISA⠀⇛ Adobe has released security updates to address a vulnerability affecting Adobe Commerce and Magento Open Source.

The simulation decision could well become the most important decision in this field as it endorses and summarises 20 years of case law since the well-known Comvik decision. The DABUS decisions follow the line taken in the UK and US that a human inventor must be named in any patent application and may be the start of a long debate on AI inventorship but are unlikely to have an immediate impact on day to day practice for most innovative companies. We discuss below these cases and other cases of interest published in 2021. # ⚓ Review_Of_EPO_Software_Decisions_In_2021⠀⇛ ䷩ 𝚕𝚒𝚗𝚎 5249 ╒═══════════════════ 𝐃𝐀𝐈𝐋𝐘 𝐋𝐈𝐍𝐊𝐒 ═════════════════════════════════════════════╕ ⠀⌧ █▇▆▅▄▃▂▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁ 02.14.22⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▂▃▄▅▆▇█ ⌧ Gemini_version_available_♊︎ ✐ Links_14/2/2022:_KDE_on_ARM⠀✐ Posted in News_Roundup at 10:14 am by Dr. Roy Schestowitz 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇GNOME bluefish⦈ § Contents⠀➾ * GNU/Linux o Distributions o Devices/Embedded * Free_Software/Open_Source * Leftovers * § GNU/Linux⠀➾ o ⚓ 9to5Linux_Weekly_Roundup:_February_13th,_2022⠀⇛ This week has been a bit slow on Linux news, probably because of the upcoming Valentine’s Day holiday, but we had some big ones like the release of the KDE Plasma 5.24 LTS desktop environment, OpenMandriva Lx 4.3 distribution, Firefox 97 web browser, OBS Studio 27.2 live streaming and recording software, as well as the KDE Frameworks 5.91 and Plasma Mobile Gear 22.02 software suites. On top of that, I take a look at the Fragments BitTorrent client as the Flatpak app of this week and the new Kalendar 1.0 calendar app for the Plasma desktop environment, and tell you all about the changes in the upcoming Ubuntu Touch OTA-22 software update for your Linux phone or tablet. You can enjoy this and much more in 9to5Linux’s Linux weekly roundup for February 13th, 2022, below! o § Audiocasts/Shows⠀➾ # ⚓ Brent’s_Betrayal_|_LINUX_Unplugged_445⠀⇛ Linux is the master of small computers, and this week it’s going to the next level. We chat with the creator of the $15 Linux box and share some significant updates for the Raspberry Pi. o § Kernel Space⠀➾ # ⚓ Red_Hat_signals_Intel’s_software-defined_silicon_will_debut in_Linux_5.18 [Ed: Simon Sharwood has turned it into prose/ clickbait]⠀⇛ Intel has revealed it plans to have its mysterious plans for software-defined silicon delivered in the next version of the Linux kernel. The existence of software-defined silicon (SDSI) emerged in October 2021 when Intel staffers posted to the Linux Kernel mailing list with hints about new functionality that would allow users to purchase licenses that turned on capabilities physically present in processors, but which are not available to use out of the box. Intel later updated its SDSI code, but maintained silence on its full capabilities, said nothing about what processors it would work with, and even suggested it might not be related to a real product. The Register has never found that stance credible: the maintainers of the Linux kernel are not fond of having junk code inserted into the project, and SDSI is too complex and tantalizing an idea for it to be an Intel thought bubble. # ⚓ Low_latency_Linux_for_industrial_embedded_systems_–_Part III_|_Ubuntu⠀⇛ Welcome to the concluding chapter of this three- part blog series on the low latency Ubuntu kernel for industrial embedded systems. Each blog is standalone and can be read independently from the others, although you may want to start at the beginning for some continuity. If you need a quick refresher on userland and kernel space, we recommend you check Part I out first. In Part II, we looked at preemption in Linux, the timer interrupt frequency, and the config options adopted by the low latency Ubuntu kernel. If you are a bit rusty with these concepts, going back to Part I and Part II may help to refresh your memory. Otherwise, keep moving as you are almost at the end of your low latency journey! # § Graphics Stack⠀➾ # ⚓ Vulkan_post-processing_layer_vkBasalt_gets_a_few tweaks_in_v0.3.2.5_|_GamingOnLinux⠀⇛ Vulkan post-processing layer vkBasalt allows Linux gamers to run various visual enhancement features, along with support for running various Reshade Fx shaders. A fantastic project that can really bring new life to older games, or to improve newer games that have a lack of good graphical tweaking options. o § Benchmarks⠀➾ # ⚓ Windows_11_no_longer_the_fastest_OS_for_Alder_Lake:_Linux 5.16_on_Core_i9-12900K_emerges_winner_in_most_benchmarks_– NotebookCheck.net_News⠀⇛ Intel Alder Lake is generally touted to run best under Windows 11 given the scheduling improvements in the new OS and the new Intel Thread Director technology that helps assign corresponding tasks to the P-cores and E-cores. However, now it looks like Linux could be the better OS of choice to extract the maximum performance from processors such as the Core i9-12900K. Since launch, Windows 11 was considered necessary for optimal performance of the Core i9-12900K. That changes now with the advent of Linux kernel 5.16 which brings better hybrid handling and other improvements. The Linux kernel 5.16 also comes with new FUTEX2 (fast user mutex) syscalls that should help with improved gaming performance, particularly for Windows games running on Wine. o § Applications⠀➾ # ⚓ How_to_install_mpd_and_ncmpcpp_on_any_ArcoLinux_desktop_| ArcoLinux⠀⇛ Mpd is a music player daemon and ncmpcpp is a music client. The client ncmpcpp runs in a terminal and connects to the daemon or server side to get the music. We start with reading the arch wiki of MPD and the arch wiki of NCMPCPP to get a general overview of what these applications are and how they can function. Google “ncmpcpp” and ask for images if you want to see what you can achieve in regards to the theming. o § Instructionals/Technical⠀➾ # ⚓ Install_Xubuntu_on_a_Raspberry_PI_–_PragmaticLinux⠀⇛ Interested in running Xubuntu on your Raspberry PI, but you can’t find an installation image for it? That’s because the Xubuntu team doesn’t offer it for the Raspberry PI’s ARMv7/v8 architecture. This doesn’t mean it’s impossible. With a few tricks you can get this Ubuntu based and lightweight XFCE desktop distribution working on your Raspberry PI. It’s not even that much work. Read on for detailed instructions on getting Xubuntu running on your Raspberry PI. # ⚓ Use_envycontrol_to_switch_between_intel/amd_and_your_nvidia graphical_card_|_ArcoLinux⠀⇛ You can find many Nvidia tutorials on this website. I will always be restricted to the hardware in my possesion. Other users have reported this tool to work great. Let me bring it under your attention. There are however other tools out there. Look at the Arch wiki page to learn more about them. # ⚓ How_to_Install_and_Configure_VNC_on_Debian_10/11_–_ByteXD⠀⇛ VNC (Virtual Network Computing) is a protocol that enables one to access the graphical desktop of a remote PC over a network connection. In addition, it allows sending keyboard and mouse signals to the remote PC, thus making tasks like managing files, applying configurations, and installing software much more accessible. In this post we will give you a step-by-step guide on how to install VNC on Debian 10 or Debian 11, how to connect to your Debian machine via VNC, and how to install multiple popular desktop environments and switch between them. # ⚓ sed_one-liner_to_extract_lines_between_two_patterns⠀⇛ Before considering how to do that, what about the reverse situation? if the user edits /etc/uimanager and changes back to icon-on-desktop, when X starts, /root/.xinitrc calls a script that will remove all lines between “STARTICONS” and “ENDICONS” in / root/.jwmrc-tray. That script is also going to be subject to the potential out-of-order writing problem. # ⚓ Install_Nmap_Network_Scanner_on_Rocky_Linux_8_– LinuxCapable⠀⇛ Nmap, also known as Network Mapper, is a free, open-source tool network administrators use to scan for vulnerabilities within their network and network discovery. Nmap allows finding devices running on their network and discovering open ports and services that, if not secure or hardened, can lead to potential hackers exploiting known vulnerabilities security risks. In the following tutorial, you will learn how to install and primary use Nmap on Rocky Linux 8 Workstation or Server. # ⚓ Install/Enable_&_Connect_to_SSH_on_Rocky_Linux_8_– LinuxCapable⠀⇛ SSH or known by its full name Secure Shell Protocol, is a cryptographic network communication protocol that enables two computers to communicate securely over an unsecured network. SSH is highly used for remote login applications and command-line executables such as terminal applications. For users wishing to connect to servers or other computers with SSH, the client and the remote connection need to both have SSH installed and enabled for this to be possible. In the following tutorial, you will learn how to install and enable SSH on Rocky Linux 35 Workstation or Server and connect to a remote PC. # ⚓ Install_Joplin_Note-Taking_App_on_Ubuntu_22.04_LTS_– LinuxCapable⠀⇛ Joplin is a free and open-source note-taking application that can be used on any computer, tablet, or smartphone. It’s been designed with both professionals in mind and consumers looking for an easy way to capture ideas anytime, anywhere without having to worry about running out of space again! The product has many features similar to those found within Evernote. Still, it offers more flexibility when editing your data – everything from font style choices down to color schemes is at the user’s disposal, meaning there isn’t one “perfect” option amongst them, which makes finding exactly what you’re after easier than ever before. For more information on the pervasive list of features Joplin offers, visit the official GitHub project page to learn more before installing. # ⚓ How_To_Install_an_FTP_Server_on_Rocky_Linux_8_With_VSFTPD⠀⇛ Vsftpd is a GPL licensed FTP server for UNIX systems, including Linux. It stands for Very Secure File Transfer Protocol Daemon. It is stable, secure and extremely fast. FTP stands for File Transfer Protocol. It has been a standard method for transferring files between computers for decades. In this guide we will learn how to install an SFTP server in Rocky linux 8 using vsftp for transferring files between client and server quickly and securely via the FTP protocol. # ⚓ Install_Qlipper_on_Ubuntu_22.04_|_20.04_to_manage_Clipboard –_Linux_Shout⠀⇛ Qlipper is a clipboard history for Linux systems, here we learn the steps to install Qlipper on Ubuntu 22.04 Jammy JellyFish and Ubuntu 20.04 Focal Fossa. Microsoft has already implemented a clipboard feature to give users access to recently copied items’ paths or files. Whereas in Linux, if you want the same, then Qlipper is one of the good options to go for. It offers a Clipboard that saves the history of items we have recently copied. This helps the user to get the history of copied items’ paths, which can be used again if he or she wants. Qlipper is a lightweight and cross-platform clipboard history applet, and will not consume many resources on your PC. The key task of Qlipper is to monitor and interact with the system’s Clipboard to save its recent data. # ⚓ How_to_build_images_with_rootless_Podman_in_Jenkins_on OpenShift_|_Enable_Sysadmin⠀⇛ It requires some configuration, but a rootless user can use Jenkins to create OCI-compliant images on OpenShift. # ⚓ Introducing_the_Wireshark_command_Line_Interface:_The TShark⠀⇛ TShark is designed as a CLI or command-line interface of Wireshark for capturing and analyzing packets right from the CLI. Most people are unaware of TShark as opposed to commonly used Wireshark. TShark comes included with Wireshark. This is particularly helpful when a GUI is not available. All the options used in Wireshark are also supported here. For e.g. captured packets can be stored in a file and later retrieved for analysis. The default capture file format is pcapng which is the same as used by Wireshark. The benefit of using TShark is that it can be included in scripts (it can be used inside a python script) and can be used on remote systems via SSH. The drawback is of course that it does not have a GUI. Like Wireshark, TShark is available for major operating systems: Linux, Mac OS, Windows. # ⚓ Learn_LVM_on_Linux_with_graphical_tools⠀⇛ The LVM, as a storage model, has been widely used on machines with Linux architectures, including PCS, NAS, and servers. Its value is self-evident. As a widely used, mature software, the tutorials of how to use LVM are already all over the internet. However, these tutorials are all based on command- line tools. The command-line tool, while powerful and complete, is complex and very unintuitive, making it difficult for users to understand LVM, especially for beginners. Just like partitioning tools, various graphical or semi-graphical (character-based) tools make partitioning easy to read in a very intuitive way. Learning LVM concepts and operations through graphical tools also greatly reduces the cost of user learning. Let’s guide you on the LVM concepts & LVM managing through graphical tools. # ⚓ How_To_Install_VNC_Server_on_AlmaLinux_8_–_idroot⠀⇛ In this tutorial, we will show you how to install VNC Server on AlmaLinux 8. For those of you who didn’t know, VNC stands for Virtual Network Computing (VNC), a system that used to remotely share and access the screen of computers. It enables users to access the remote computer’s graphical desktop and send mouse clicks and keyboard strokes to the remote system. 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 VNC Server on an AlmaLinux 8. You can follow the same instructions for Fedora, RHEL, CentOS, and Rocky Linux distributions. # ⚓ Writing_Your_Own_Sudo⠀⇛ One might think that sudo is actually some binary deeply integrated into the kernel, relying on a special purpose-built system call to achieve its functionality. After all, it lets you use root without even providing the password for that account! But thanks to one bit inside file permissions, sudo can exist without any of this. # ⚓ Deploy_your_private_cloud_by_installing_nextcloud_on_Rocky Linux_8_/_Alma_Linux_8⠀⇛ In this post, you will learn how to install Nextcloud on Rocky Linux 8. As we all know, with Nextcloud, we can deploy our private cloud where we don’t have to trust our files to anyone. For this very reason, is that many companies have instances to share data between workers without trusting third parties that can steal data. So let’s go for it. # ⚓ How_to_install_NodeJS_with_MongoDB_on_Ubuntu_|_FOSS_Linux⠀⇛ NodeJS is an open-source JavaScript runtime created on Chrome’s V8 JS engine. It uses a non-blocking lightweight event-driven input-output model that makes it possible for asynchronous programming. It can be referred to as a serverless environment that runs JS-based scripts to build scalable apps. NodeJS is primarily known for building scalable and fast network apps. Developers know it as a programming language used for websites, event- driven servers, and active backend APIs. Therefore, NodeJS has been termed a “JavaScript everywhere” regime due to its ability to integrate app and web development around a single Programming language. # ⚓ 15_examples_of_different_usage_of_ffmpeg⠀⇛ ffmpeg was created by Fabrice Bellard the same creator as QEMU and QuickJS, the engine behind JSLinux. In addition to the conventional conversion commands that we use on a daily basis, let’s see 15 more utilities that can be good for you in many cases. # ⚓ How_I_configure_Vim_as_my_default_editor_on_Linux_| Opensource.com⠀⇛ I have used Linux for about 25 years and Unix for a few years before that. During that time, I have developed preferences for some tools that I use daily. One of the most important tools I use is the Vim editor. I started using Vi when I learned Solaris in the early ‘90s because I was told that it would always be available on any system, which is true in my experience. I have tried other editors, and they all do the job. However, I find that Vim works best for me, and I use it so much that my Vim muscle memory causes me to attempt to use its command keystrokes even with other editors. Plus, I just really like Vim. Many configuration files use Vi instead of Vim, and you can run the vi command. However, the vi command is a link to vim. Many Linux tools use editors that emulate or just call Nano, Emacs, or Vim. Some other tools allow users—like those with clear preferences—to link to their favorite editor. The two examples that affected me the most were Bash command-line editing, which defaults to Emacs, and the Alpine text-mode email client, which defaults to the Pico editor. In fact, the Pico editor was written explicitly for use in the Pine email client, which is the predecessor to Alpine. # ⚓ A_guide_to_Kubernetes_architecture_|_Opensource.com⠀⇛ You use Kubernetes to orchestrate containers. It’s an easy description to say, but understanding what that actually means and how you accomplish it is another matter entirely. If you’re running or managing a Kubernetes cluster, then you know that Kubernetes consists of one computer that gets designated as the control plane, and lots of other computers that get designated as worker nodes. Each of these has a complex but robust stack making orchestration possible, and getting familiar with each component helps understand how it all works. # ⚓ Delete_Files_with_Specific_Extension_in_Linux_Command Line⠀⇛ You might have a situation where you want to remove multiple files that have a particular extension. This tutorial will help you do exactly that. # ⚓ How_to_Use_Debug_Module_in_Ansible_Playbook⠀⇛ Ansible provides hundreds of modules which are reusable standalone scripts that get executed by Ansible on your behalf. The Ansible debug module is a handy module that prints statements during playbook execution. Additionally, it can be used to debug expressions and variables without interfering with the playbook execution. In this guide, we are going to demonstrate how to use debug module in ansible playbook with examples. # ⚓ How_to_Install_Wine_7.0_in_Ubuntu_Desktop⠀⇛ Wine is the ultimate solution for Linux users on distros like Ubuntu that still have an eye for the Windows operating system experience. With Wine’s compatible layer on Linux, it is possible to interact with your favorite Windows applications on a Linux environment. Wine’s advantage over virtual machines and emulators is that Windows API calls are translated into POSIX calls, disregarding the simulation of internal Windows logic (an approach by emulators and virtual machines). Wine’s approach in running Windows applications saves it from memory and performance penalties resulting in the seamless integration of Windows applications on your Ubuntu Desktop. # ⚓ Install_Qlipper_on_Ubuntu_22.04_|_20.04_to_manage_Clipboard –_Linux_Shout⠀⇛ Qlipper is a clipboard history for Linux systems, here we learn the steps to install Qlipper on Ubuntu 22.04 Jammy JellyFish and Ubuntu 20.04 Focal Fossa. Microsoft has already implemented a clipboard feature to give users access to recently copied items’ paths or files. Whereas in Linux, if you want the same, then Qlipper is one of the good options to go for. It offers a Clipboard that saves the history of items we have recently copied. This helps the user to get the history of copied items’ paths, which can be used again if he or she wants. Qlipper is a lightweight and cross-platform clipboard history applet, and will not consume many resources on your PC. The key task of Qlipper is to monitor and interact with the system’s Clipboard to save its recent data. o § Games⠀➾ # ⚓ Send_help_as_I_have_discovered_Super_Auto_Pets_| GamingOnLinux⠀⇛ Sent in by a reader a while ago and one I’ve been meaning to try out properly, Super Auto Pets is a free to play auto-battler from Team Wood Games that’s delightfully good. A game that’s annoyingly moreish, as you’re going to want to play through just one more run. Auto-battling probably doesn’t need much of an introduction: you carefully build up a team of creatures, then proceed to turn-based battles that happen automatically without your direct input. In between each round you go back to the preparation area to sell creatures, level them up, buy new more advanced creatures or perhaps give them an extra bonus or two. Then it’s back to battling and repeat. Here the battles are one-dimensional though, so your positioning is a vital part of the strategy as they will fight at the front until one is down, then the next and so on. # ⚓ Welcome_to_Elk_readies_up_for_the_Steam_Deck_and_Proton_| GamingOnLinux⠀⇛ A biographical adventure set on an island like no other, Welcome to Elk from developer Triple Topping has a new update available that aims to make the experience on Linux with Steam Play Proton and the Steam Deck better. # ⚓ Doom_Shinobi_is_my_new_favourite_GZDoom_mod_| GamingOnLinux⠀⇛ Running it on Linux is easy. S # ⚓ Friendship_Games_Week_is_live_on_Steam_showing_off_local multiplayer_games_|_GamingOnLinux⠀⇛ Want to build up a bigger collection of games to play with friends or a partner? Check out the Friendship Games Week that’s live now on Steam. Arranged by Frogsong Studios, the event runs until February 21. Featuring a mix of games that support split-screen, co-op, local multiplayer and more this is a hand- picked selection of some great picks and unknown gems to take a look over. An easy way for you to find something new to buy or stick on your wishlist. A number of included games are also on sale too so perhaps time to find a bargain. o § Desktop Environments/WMs⠀➾ # § K Desktop Environment/KDE SC/Qt⠀➾ # ⚓ KDE’s_Dolphin_File_Manager_Finally_Brings_Root_File Operations._Here’s_How_to_Use⠀⇛ After five years of making, root file operation finally lands in the Dolphin file manager of KDE Plasma desktop. Here’s how to use Dolphin with root access. # ⚓ KDE’s_Latest_Move_Will_Help_Raspberry_Pi_and PinePhone_Pro_Users_Immensely_–_It’s_FOSS_News⠀⇛ KDE recently shared its monthly updates on the latest app developments and progress, as usual. While the Falkon 3.2 release was a significant upgrade, there were several other updates/bug fixes to other KDE applications. However, there was one interesting thing about it. [...] Considering the early developments for the ARM platform, I’d say it is good progress when compared to the number of devices available. As of now, the Raspberry Pi users and the PinePhone pro users can immediately benefit from new KDE applications. As we start to see more ARM-powered devices or laptops, you should expect almost everyone to start prepping for ARM. o § Distributions⠀➾ # ⚓ Kali_Linux:_The_Most_Accessible_Distro_on_The_Planet [Ed: Sadly, towards the end it 'shills' WSL (Windows, E.E.E.) a little]⠀⇛ Kali Linux, Debian-derived Linux Distribution keeps getting better. When I learned about this Linux Distribution a few years ago it had the reputation it has today and with time, many things about this Distro changed, fortunately for the better. Unlike Parrot OS at the time, Kali was heavy on hardware. And, even though to some that might still be the case the available options we have today make up for most of that. Depending on how you look at things the hardware requirements necessary to have this distro up and running can be justified I mean, what would one use Kali for with only 1GB of RAM and a single-core CPU with 1GHz speed? This obviously wouldn’t provide the best experience besides the fact that some of the tools on this OS perform better with the minimum requirements or better. # § Reviews⠀➾ # ⚓ Review:_Slackware_Linux_15.0⠀⇛ Slackware Linux is the world’s oldest surviving Linux distribution. The distribution is a slow moving project, often with several years between releases. The gap between Slackware 14.2 and the latest 15.0 release was about five and a half years, for example. Slackware has a well deserved reputation for stability and for having a simple technical design. A design which frequently ignores modern approaches to system management. Slackware still uses a text-based system installer, has 90s-era approaches to package management, and prefers editing text files over graphical tools when it comes time to adjust most configuration settings. The distribution’s official media does not offer a live desktop environment, though there is a community branch which provides live media for people who wish to test the distribution on their hardware. The project’s official release announcement acknowledges this slow- to-change style, noting Slackware is just now adopting PAM authentication (something most other Linux distributions have used since the 1990s) and continues to use the classic SysV init software instead of systemd: “We adopted PAM (finally) as projects we needed dropped support for pure shadow passwords. We switched from ConsoleKit2 to elogind, making it much easier to support software that targets that Other Init System and bringing us up-to-date with the XDG standards. We added support for PipeWire as an alternate to PulseAudio, and for Wayland sessions in addition to X11.” In other words, while Slackware runs a lot of modern software such as KDE Plasma 5.15, version 5.15 of the Linux kernel, and PipeWire the underlying style and approach are still very much the same as they were 25 years ago. Slackware 15.0 is available for 32-bit and 64-bit builds of the x86 architecture. There is also an ARM branch of the project, though install media for it was not available on release day. The 64-bit (x86_64) build is a 3.6GB download. The Slackware media boots to a text screen where we can select kernel options. This is followed by a second text screen where we are given the chance to select a keyboard map. The install media then drops us at a console login prompt where we can sign in as root without a password. Above the login prompt is a helpful message letting us know we will need to format the disk and set up at least one partition, then run the setup command in order to get started. # § IBM/Red Hat/Fedora⠀➾ # ⚓ How_To_Migrate_from_AlmaLinux_8_To_Rocky_Linux_8_– Linux_Shout⠀⇛ Learn the commands to convert Almalinux into Rocky Linux server or desktop using the terminal with the help of an official script. With the announcement of RedHat that it is dropping the long-term support in CentOS 8, other developers came with their own similar Linux distro- Almalinux & Rocky Linux 8 are one of those. Well, both Almalinux & Rocky are based on RedHat Enterprise Linux with one-to-one binary compatibility. Although it is not necessary to move from Almalinux to Rocky because both are the same, except the developers behind them. Both are community enterprise Linux distributions and downstream to RHEL. Nevertheless, still due to any reason you want to switch from AlmaLinux to Rocky, the official developers of “Alma” provide a script that automates the migration process smoothly. # ⚓ Vanessa’s_Blog_|_Career_Opportunities⠀⇛ Fedora gave me the opportunity to learn more about the Linux distro. Now I make applications for the Linux Fedora operating system. I’m sure with a little research I’ll be able to package for other Linux distros # ⚓ Serialize_Debezium_events_with_Apache_Avro_and OpenShift_Service_Registry_|_Red_Hat_Developer⠀⇛ Change data capture (CDC) is a powerful data processing tool widely used in the industry, and provided by the open source Debezium project. CDC notifies your application whenever changes are made to a data set so that you can react promptly. This tutorial demonstrates how to use Debezium to monitor a MySQL database. As the data in the database changes, the resulting event streams are reflected in Red Hat OpenShift Streams for Apache Kafka. Debezium includes connectors for many types of data stores. In this tutorial, we will use the MySQL connector. # ⚓ IT_leadership:_How_to_recognize_and_manage_change fatigue⠀⇛ Over the past two years, people have faced significant change in nearly every facet of their lives. Adjusting to this much change so quickly can be exhausting – making change fatigue a growing concern for many of us. As an IT leader, you need to proactively address this issue to maintain your teams’ health and productivity. After all, your company’s biggest asset is not your products, your services, or your capabilities ‒ it’s your people. In a recent Gartner survey of 274 HR leaders, 54 percent say their employees are fatigued from all the change. It’s driven by both large-scale, organization-wide changes and small day-to-day adjustments. What might seem like a minor change or system shift could be making a big impact on your team. [...] It’s critical to understand the amount of change your organization can effectively handle. In a recent Prosci survey, 73 percent of respondents said that their organizations were near, at, or beyond the change saturation point. Organizations that have reached that critical point of change saturation often begin to experience these negative effects: project priorities changing, bottlenecks emerging, progress and productivity slowing, client and customer complaints increasing. # ⚓ IBM_executives_called_older_workers_‘dinobabies’_who should_be_‘extinct’_in_internal_emails_released_in_age discrimination_lawsuit⠀⇛ Internal emails show IBM executives calling older workers “dinobabies” and discussing plans to make them “an extinct species,” according to a Friday filing in an ongoing age discrimination lawsuit against the company. The documents were submitted as evidence of IBM’s efforts “to oust older employees from its workforce,” and replace them with millennial workers, the plaintiff alleged. It’s the latest development in a legal battle that first began in 2018, when former employees sued IBM after the company fired tens of thousands of workers over 40-years- old. One high-ranking executive, whose name was redacted from the lawsuit, said IBM had a “dated maternal workforce.” “This is what must change,” the email continues, per the filing. “They really don’t understand social or engagement. Not digital natives. A real threat for us.” The exchanges are “highly incriminating” and “reflects age animus from IBM’s highest ranks,” plaintiff Shannon Liss-Riordan wrote. Liss-Riordan is a well-known employment lawyer who has represented workers in cases against Google, Amazon, and Uber. # § Debian Family⠀➾ # ⚓ Peppermint_OS_11_Released:_6_New_Features_to_Expect⠀⇛ If you are a Linux enthusiast, you have a reason to rejoice. After three long years, Peppermint OS 11 is ready to grace your desktop again. With OS 11, Peppermint aims to deliver cutting-edge, open-source Linux computing, even for your low-end systems. Peppermint OS 11 makes a few tectonic changes since its predecessors, that are bound to impress you. Read on if you want to learn about the new features of Peppermint OS 11 before installing a copy of the distro. # ⚓ Petter_Reinholdtsen:_Updated_vlc_bittorrent_plugin_in Debian_(version_2.14)⠀⇛ I am very happy to report that a new version of the VLC bittorrent plugin was just uploaded into debian. The changes since last time is mostly code clean in the download code. The package is currently in Debian unstable, but should be available in Debian testing son. To test it, simply install it like this: apt install vlc-plugin-bittorrent o § Devices/Embedded⠀➾ # ⚓ Round_color_LCD_board_comes_in_Raspberry_Pi_RP2040_or ESP8266_flavor_(Crowdfunding)⠀⇛ Roundy is a board with a 1.28-inch round color LCD with 240 x 240 resolution that is offered with either a Raspberry Pi RP2040 MCU or an ESP-12E WiFi module, with the variants respectively called RoundyPi and RoundyFi. Both boards come with a micro USB port for power and programming, a button for flashing the firmware, and six pins with power signals and four GPIOs. One difference is that the Raspberry Pi RP2040 board includes a MicroSD card for data storage. # § Mobile Systems/Mobile Applications⠀➾ # ⚓ Google_Voice_for_Android_adds_Smart_Reply_suggestions –_9to5Google⠀⇛ # ⚓ Android_12_has_hidden_feature_which_makes_reading while_you’re_in_bed_easier⠀⇛ # ⚓ OPPO_Reno6_5G_Gets_Android_12_Update_in_Kenya⠀⇛ # ⚓ Carrier-locked_Galaxy_Z_Fold_2_getting_Android_12 update_in_the_US_–_SamMobile⠀⇛ # ⚓ Snapdragon_8_Gen_1_PLUS_Rumored_to_Release_‘Early,’ Replacing_Qualcomm’s_Flagship_Chipset_on_Android_Phones |_Tech_Times⠀⇛ # ⚓ Nubia_Z40_Pro_to_be_first_Android_phone_with_magnetic wireless_charging_tech⠀⇛ # ⚓ Android_13_virtualization_lets_Pixel_6_run_Windows 11,_Linux_distributions_–_CNX_Software⠀⇛ The first Android 13 developer preview may have felt a bit underwhelming, but there’s a hidden gem with full virtualization possible on hardware such as the Google Pixel 6 smartphone. What that means is that it is now possible to run virtually any operating system including Windows 11, Linux distributions such as Ubuntu or Arch Linux Arm on the Google Tensor-powered phone, and do so at near- native speed. o § Free, Libre, and Open Source Software⠀➾ # ⚓ Best_Free_and_Open_Source_Alternatives_to_Adobe_Audition⠀⇛ Adobe is a large multinational computer software company with over 22,000 employees. Its flagship products include Photoshop, Illustrator, InDesign, Premiere Pro, XD, Acrobat DC, and the Portable Document Format (PDF). The products are wrapped up and marketed as the Creative Cloud, a subscription- only way of accessing more than 20 desktop and mobile apps and services for photography, design, video, web, UX, and more. We are long-standing admirers of Adobe’s products. They develop many high quality proprietary programs. It’s true there are security and privacy concerns in relation to some of their products. And there’s considerable criticism attached to their pricing practices. But the real issue is Adobe Creative Cloud does not support Linux. And there’s no prospect of support forthcoming. # § Productivity Software/LibreOffice/Calligra⠀➾ # ⚓ Collabora_Online_–_A_Real_Alternative⠀⇛ As humans we’re bad at change; we much prefer what we know and actively protect the status quo. Like it or not, the uncertainty we’ve all experienced over the last two years has forced change upon us. This has challenged organisations to find real alternative solutions to new operational challenges, such as homeworking, and question many of the norms that had previously been ‘set in stone.’ For most organisations, office document functionality underpins their productivity. We’ve all relied on it for years without giving it much thought – it was ‘set in stone.’ Yes, software updates and improvements in functionality have been introduced over the years, but the basic environment has remained familiar, which has helped maintain productivity. As its name suggests, office document software has been optimised for a traditional office environment. For most organisations pre-pandemic this meant manageable, predictable office buildings in which their staff gathered together to work. The need to enable and support widespread homeworking changed all of this. # ⚓ Talks_and_Slides_by_Collabora_at_FOSDEM_2022_– Collabora_Office_and_Collabora_Online⠀⇛ Whether on-site in Brussels or as an online event like the last two years, FOSDEM is and remains the largest and most important gathering of Open-Source developers in Europe. We’d like to express our gratitude to the community and the organisers. The Collabora team gave numerous talks in the LibreOffice Technology devroom. Missed a presentation? Below you will find links to all videos and to the downloads of the slides. * § Leftovers⠀➾ o ⚓ We_Cannot_Truly_Die⠀⇛ Based upon reams of fascinating scientific and metaphysical research, Selbie connects the dots in a masterful blend of science and religion taken to the edge of multi-universes and beyond to the heart of the astral plane. Our existence is much more than a boring standardized physical life on Earth. Selbie offers an uplifting view of so much more with considerable science-based evidence as well as personal experiences by people of intellectual stature. Life on our planet is but one small leg of a much bigger journey, a phenomenal journey unlike anything ever experienced or ever dreamed, in as much as, we truly cannot die. o § Science⠀➾ # ⚓ Four-story_high_rogue_wave_breaks_records_off_the_coast_of Vancouver_Island⠀⇛ The wave made a splash in the scientific community for being proportionally the most extreme rogue wave ever recorded. Although it occurred in November 2020, the study confirming it was just released February 2 of this year. # ⚓ Watch_how_SpaceX_Starlink_satellites_died_after_being_hit by_geomagnetic_storm⠀⇛ Stargazers were in for a surprise early this week when they spotted fiery tails shooting past in the skies. While they thought these were meteors that had entered Earth’s atmosphere, they turned out to be dead Starlink satellites. 40 of the 49 Starlink satellites launched last week returned to Earth in pieces as they burned up in the atmosphere. The 40 satellites were hit by a deadly geomagnetic storm that originated from the Sun last week and struck Earth’s magnetic field on February 4. The fiery demise of the satellites one after another was captured by a camera operated by the Sociedad de Astronomia del Caribe, a Puerto Rico-based nonprofit organisation. o § Health/Nutrition/Agriculture⠀➾ # ⚓ Opinion_|_GOP_Curbing_Access_to_Medication_Abortions_Across the_South⠀⇛ When the Food and Drug Administration announced in December that it would permanently allow the drugs used for medication abortion to be delivered through the mail, it seemed like a victory for abortion access—especially during the coronavirus pandemic, which has expanded the use of telemedicine for health care. # ⚓ Arrests_at_US-Canada_Border_Finally_Bring_End_to_Anti- [Mandate]_Blockade⠀⇛ In the face of accusations that Canadian officials have been too tolerant of anti-vax conspiracy theorists and anti-mandate advocates laying siege to public motorways in the country, law enforcement in Windsor, Ontario just before dawn Sunday finally began to make arrests and subsequently cleared the road leading to the U.S. border after days of protest. According to the Windsor Star: o § Integrity/Availability⠀➾ # ⚓ [Old] choosing_safe_curves_for_elliptic-curve cryptography⠀⇛ Unfortunately, there is a gap between ECDLP difficulty and ECC security. None of these standards do a good job of ensuring ECC security. There are many attacks that break real-world ECC without solving ECDLP. The core problem is that if you implement the standard curves, chances are you’re doing it wrong: [...] # § Proprietary⠀➾ # ⚓ Vulnerabilities_that_aren’t._Unquoted_Spaces⠀⇛ I’ve covered a couple of web vulnerabilities that (mostly) aren’t, and now it’s time for a Windows specific one. A common finding from build reviews and CIS comparisons: unquoted spaces in service or run paths. # ⚓ Bye_Microsoft_Edge!_Vivaldi_is_the_best_Chrome alternative [Ed: Proprietary vs proprietary vs proprietary]⠀⇛ When I reviewed Microsoft Edge last year, I found its performance and experience unparalleled among peers like Google Chrome. But one concern prevented me from accepting that default browser pop-up, and I suspected it could be a fatal dealbreaker. “On Edge, Microsoft constantly attempts to push you to use its in-house services,” I wrote and wondered whether Microsoft would get more aggressive once it claimed a larger piece of the browser market. Over six months later, Microsoft has, unfortunately, proven me right. Since that review, Edge’s popularity has soared, but so has the amount of bloatware. In the last couple of updates, Microsoft has outfitted Edge with a range of spammy features. The browser now offers loans to users and allows them to split online payments into installments. It has a new price tracker, mini games, a math solver, a reviews aggregator, and more. What’s worse, Microsoft has been actively abusing its Windows platform advantage to keep users from switching to other browsers. Not only is changing the default browser more complex and tedious than ever, but Microsoft force installed a ransomware-esque Windows update that launches a full-screen Edge ad users can’t skip or close. Microsoft was punished for pulling similar tricks decades ago with Internet Explorer, and I won’t be surprised if it comes under scrutiny again for its renewed browser ambitions. # § Security⠀➾ # § Fear, Uncertainty, Doubt/Fear-mongering/ Dramatisation⠀➾ # ⚓ Cryptojacking_targeting_Linux-based systems [Ed: This campaign_of_hate_and_FUD against GNU/Linux carries on]⠀⇛ Cryptojacking and evolving ransomware attacks are not only sophisticated and harder to detect but are now also targeting Linux-based operating systems. o § Defence/Aggression⠀➾ # ⚓ ‘Love_to_Afghanistan’_Vigils_to_Demand_Return_of_$7_Billion Stolen_by_US⠀⇛ With the people of Afghanistan facing one of the most severe humanitarian crises in the world, U.S.- based peace activists—who largely blame the policies of their own government for inflicting pain on millions of innocent Afghans—are using Valentine’s Day on Monday to demand the Biden administration return billions of dollars of seized assets to the war-torn country before more lasting harm and “cruelty” is done. Under the banner of “Love to Afghanistan,” nationwide actions were scheduled for the weekend and localized vigils organized set for Monday (Feb. 14) by Peace Action, World Beyond War, and other humanitarian groups who argue that $7 billion frozen by the U.S. government and subsequently seized by an executive order issued Friday by President Joe Biden rightfully belongs to the Afghan people, who without it face an economy on the brink of collapse and a healthcare system and federal infrastructure without adequate support amid the Covid-19 pandemic and a worsening food crisis. # ⚓ This_Prison_in_California_Forced_Incarcerated_People_to Drink_Arsenic_for_Years⠀⇛ # ⚓ Sweden:_Islamist_Party_Promises_to_Take_Over_Southern Swedish_Region⠀⇛ In the below article from Nya Dagbladet, the party’s leader, Mikail Yüksel, has promised that they will “take over” the southern Swedish region of Skåne, which includes Malmö, Sweden’s third- largest city and a hotbed of Islamism and anti- Semitism. The article is translated by Fousesquawk. # ⚓ Countries_That_Have_Banned_Burqa_And_What_International_Law Says_About_It⠀⇛ Several European and Asian countries have banned burqas, hijabs and veils, courting controversies, that to date, remain unresolved. As the controversy around the Karnataka hijab row flares up, here’s a look at countries that have put a ban on veils. o § Environment⠀➾ # ⚓ Most_Mega-Corporations’_Net-Zero_Pledges_Are_Hollow,_Report Finds⠀⇛ # § Wildlife/Nature⠀➾ # ⚓ Explained:_Why_Australia_has_listed_koalas_as endangered_species⠀⇛ Once found in abundance, Australia’s much- loved koalas have now been officially classified as ‘endangered’ after widespread bushfires, drought and land clearing destroyed much of their eucalyptus-rich habitat. Australia’s environment minister Sussan Ley on Friday announced that the government was upgrading the conservation status of the marsupials from ‘vulnerable’ to ‘endangered’ in Queensland, New South Wales and the Australian Capital Territory, based on the recommendation of the threatened species scientific committee. # ⚓ Owl_photos_are_flooding_the_internet_ahead_of_the Super_Bowl._Here’s_why⠀⇛ Instead of Super Bowl information, one small typo later and your search results are filled with owl content instead. And we’d like to encourage you to lean into the error. Because owls truly are “superb.” o § Finance⠀➾ # ⚓ Opinion_|_On_Super_Bowl_Sunday,_Can_the_NFL_Be_More_Than_a Playground_for_Billionaires?⠀⇛ The billionaire owners of the NFL might like to think they have — in their annual Super Bowl extravaganza — the world’s biggest sports event. But the driving passion of more fans globally than any other sport remains what the world calls football and what Americans see as soccer. o § AstroTurf/Lobbying/Politics⠀➾ # ⚓ ‘A_Better_Texas_Is_Possible’:_Ocasio-Cortez_Rallies_for Cisneros,_Casar⠀⇛ Congresswoman Alexandria Ocasio-Cortez of New York spent the weekend in Texas as she headlined rallies with a pair of progressive candidates vying to join her in Washington, D.C. next year by winning upcoming elections in the Lone Star State. With Democratic primary in Texas set for March 1, Ocasio-Cortez appeared at events for both Jessica Cisneros, challenging Democratic incumbent Rep. Henry Cuellar in District 28, and Greg Casar, running for an open seat in the state’s newly- created District 35. Both districts stretch from Austin to areas in and around San Antonio. # ⚓ Blockades_on_Canada-US_border_continue_as_protests_swell⠀⇛ The tense standoff at the Ambassador Bridge linking Detroit and Windsor, Ontario, eased somewhat early in the day when Canadian police persuaded demonstrators to move the trucks they had used to barricade the entrance to the busy international crossing. But protesters reconvened nearby — with reinforcements — and were still choking off access from the Canadian side late Saturday, snarling traffic and commerce for a sixth day. About 180 remained late Saturday in the sub-freezing cold. # ⚓ Canada’s_Trucker_Blockades_Are_a_Warning⠀⇛ The blockades are very much a rogue movement. They have been condemned by the Canadian Trucking Alliance and Canada’s Teamsters Union. About 90 percent of Canadian truck drivers are vaccinated; comparatively few of those protesting are professional truck drivers. The protesters are not anti-lockdown. They are anti-vaccination. The spark for the protests was a requirement that truckers be vaccinated to cross the U.S.-Canada border. This is not a movement of “working class” protesters against remote, affluent elites. The burden of the protests has fallen on Ottawa residents, whose streets have been paralyzed, and Canadian autoworkers, who face factory shutdowns because of cross-border disruptions. o § Misinformation/Disinformation⠀➾ # ⚓ The_West_is_a_player_in_the_Ukraine_information_war._Unlike Russia,_it_has_to_convince_the_public⠀⇛ But while the US government declassified the information about the alleged plot last week, it didn’t share any of its underlying evidence with the public. In a heated briefing room exchange last week, journalists demanded proof to support the claim, with one reporter accusing the State Department of veering into “Alex Jones territory.” o § Censorship/Free Speech⠀➾ # ⚓ In_India,_comedians_can_face_arrest_for_making_the_wrong kind_of_jokes⠀⇛ Experts say India’s colonial-era laws are being used by Prime Minister Narendra Modi’s Hindu- nationalist Bharatiya Janata Party (BJP) government to quash criticism and encourage self-censorship. # ⚓ The_Heritage_Foundation_Wants_To_Break_the_Internet⠀⇛ Frederick starts by detailing certain censorial actions by “Big Tech” firms, which she defines as the “Big Five” of Alphabet (which owns Google), Amazon, Apple, Meta (which owns Facebook), and Microsoft, plus companies like Twitter, Snapchat, TikTok, and Netflix, “whose cultural and political impacts on public debate are important.” Indeed, some of the incidents detailed are troubling: Social media platforms blocking users from sharing a New York Post article about Hunter Biden just weeks before the 2020 election, YouTube suspending videos of politicians for simply discussing public health topics, etc. Obviously, none of these are First Amendment violations, as private companies can allow or disallow any speech they please, but these actions do detract from a culture of free speech. # ⚓ Pakistan:_Mob_stones_man_to_death_for_alleged_Quran burning⠀⇛ The crowd began throwing stones at the man and the officers, according to the local police. The mob, which included some 300 people, then hanged his body from a tree. Videos shared on social media showed a large crowd gathered at the site. o § Freedom of Information/Freedom of the Press⠀➾ # ⚓ Attacks_on_Journalists_Are_Just_One_Looming_Threat_to_Press Freedom_in_the_US⠀⇛ # ⚓ Mexico_Journalist_Murders:_Fear_And_Lawlessness_Driving Force?⠀⇛ A spate of journalist murders shows that Mexico isn’t just failing to protect its reporters but that lawlessness is a systemic problem and a legacy of the failed “war against drugs,” experts warn. o § Civil Rights/Policing⠀➾ # ⚓ Opinion_|_Dear_President_Biden:_Clemency_for_Leonard Peltier_Now⠀⇛ Leonard Peltier is a 77-year-old Anishinabe-Lakota Native American activist imprisoned for 46 years for a crime he says he did not commit. Amnesty International calls him a political prisoner. Peltier recently contracted COVID-19 inside the Coleman maximum security federal penitentiary in Florida, where prisoners have reportedly been denied vaccine booster shots. # ⚓ Why_more_and_more_US_universities_are_adding_caste_to_anti- discrimination_policies⠀⇛ 1 in 3 Dalit students in US experienced caste discrimination, according to Equality Labs report, 2016. These efforts culminated in a landmark decision of CSU, the largest four-year public university in the US, with 23 campuses and close to half a million students, to add caste to its anti- discrimination policy in January. # ⚓ Lynching_horror_visits_Khanewal⠀⇛ The Saturday incident took place in Jungle Dera village where hundreds of loc­als gathered after Magh­rib pra­yers following annou­n­cements that a man had torn some pages of the Holy Quran and later set them on fire. With no one ready to listen to the suspect, who rep­orte­dly claimed innocence, the villagers first hanged him with a tree and then hit him with bricks, until he died. # ⚓ As_Paris_walked_by,_a_photographer_died._Can_it_bring compassion_to_streets?⠀⇛ The death of elderly Swiss photographer René Robert, ignored by passersby for nine hours after he collapsed on a cold Parisian street, has been a wake-up call to French authorities to the plight of the country’s homeless people, for whom such a fate is more likely. # ⚓ Banning_foreigners_is_scapegoating_that_goes_against_ubuntu –_Maimane⠀⇛ Maimane said there had been a systemic failure to create jobs through inclusive economic growth and a modernised basic education system. o § Internet Policy/Net Neutrality⠀➾ # ⚓ Comments_to_the_TRAI_for_the,_“Consultation_Paper_on Regulatory_Framework_for_Promoting_Data_Economy_Through Establishment_of_Data_Centres,_Content_Delivery_Networks,_and Interconnect_Exchanges”⠀⇛ IFF has submitted comments pursuant to the Telecom Regulatory Authority of India’s (TRAI) “Consultation Paper on Regulatory Framework for Promoting Data Economy Through Establishment of Data Centres, Content Delivery Networks, and Interconnect Exchanges” (Consultation Paper). Our comments are threefold. They call for urgency in the creation of a multi-stakeholder body for the enforcement of net neutrality. We then caution against regulating CDNs given existing market efficiency. Finally, we urged the TRAI to recast focus towards telecom companies practises for data protection standards rather than adopting flawed technical systems of consent (eg. DEPA). [...] Given such framing, obvious issues of innovation that serve users, net neutrality and data protection emerge for consideration. We believe this is an important consultation and given it’s seriousness intend to also file counter-comments. At the same time we encourage members of the general public and, — academics, network engineers, technologists and digital rights groups to participate. Our submissions which are attached below fall within three primary buckets in which we have provided comments specific to digital rights. Broadly these concern questions on CDN regulation, issues of privacy and net neutrality. o § Monopolies⠀➾ # § Copyrights⠀➾ # ⚓ David_Fisher:_10_years_of_Megaupload,_10_things_we learned⠀⇛ On January 20, 2012, a high-profile dawn raid by armed police to arrest Megaupload founder Kim Dotcom and friends at his $30 million mansion. Herald senior writer David Fisher has covered the case . On the 10th anniversary of the raid, he looks back at what we learned – and what we still don’t know. # ⚓ Rightsholders_See_Iraq_as_a_‘Corrupt’_Hotbed_for Online_Piracy,_Ask_the_U.S._to_Step_In⠀⇛ Several copyright holders are urging the United States Trade Representative to help tackle the unbridled piracy that takes place in Iraq. They describe the country as a hotbed for online piracy services which are also exported to Europe and the US. Due to lacking copyright laws and systematic corruption, external pressure is needed, they argue. # ⚓ ACE_Seize_Pirate_IPTV_Domains,_Press_Cloudflare_to Hand_Over_Identitities⠀⇛ The MPA and Alliance for Creativity and Entertainment are pressing ahead with their campaign to eliminate as many pirate services from the web as possible. Their latest activities include the seizure of a number of pirate IPTV-related domains and additional pressure on Cloudflare and domain registry Tonic to hand over information they hold on yet more pirate site operators. ╘══════════════════════════════════════════════════════════════════════════════╛ ¶ Lines in total: 7090 ➮ Generation completed at 02:41, i.e. 69 seconds to (re)generate ⟲
