      • 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.

        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.

    • 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).

      • 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.

      • 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.

      • 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.

      • 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.

      • 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.

        • 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.

        • 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.

          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.

        • 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.

        • 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.

          • 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.

      • 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.

            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.
