    • Linux Distros: Year in Review

      2021 was a pretty exciting year for Linux distributions within the cloud native and developer world. Not only did two CentOS replacements release new iterations, but they also reached a level of stability to surpass that of the platform they replaced (Red Hat changed the direction of CentOS late last year towards a more experimental approach).

      And although there were no new distributions released that were purpose-built for cloud, container, and edge use cases, there were plenty of updates for other operating systems that strengthened the offerings to make nearly every Linux server distribution widely appealing to most businesses and developers.

      • System76 Launches Pop!_OS 21.10 with Linux 5.15 LTS, New Application Library

        Coming almost six months after Pop!_OS 21.04, the Pop!_OS 21.10 release introduces a new Application Library feature for its GNOME-based desktop environment that replaces the big Application Wall window that opened in full-screen when you wanted to search for and open an installed application.

        Now, in Pop!_OS 21.10, the Application Library feature, which you can access it from the dock, menu bar, using a 4-finger swipe, or the Super+A keyboard shortcut, will open in a smaller window over the current workspace.

      • Linux needs to be pre-installed on more hardware to hit mainstream

        Honestly, it really is that simple. There's a fair bit of that now already with the likes of System76, Slimbook, TUXEDO , Star Labs and others I'm forgetting. However, none of those are particularly known outside of Linux circles (TUXEDO claim otherwise). Even if they're slowly pulling in newer non-Linuxy customers, they're still tiny and often expensive. Other vendors like Dell and Lenovo may have a few but they're often harder to find. It's a bit like the old Linux gaming loop — people don't want to switch due to "no games" and developers don't want to support directly due to "no users". Vendors don't often do it because they don't perceive there to be enough interest.

      • System76 Releases Pop!_OS 21.10

        Linux PC vendor System76 has released Pop!_OS 21.10 as the newest version of their Ubuntu-based operating system.

        Pop!_OS 21.10 is the latest version of their popular open-source desktop OS that features desktop improvements and other mostly UI alterations compared to Ubuntu 21.10. One of the new features with Pop!_OS 21.10 is its "Application Library" window that they aim as an alternative to GNOME's Application Wall.

      • Pop!_OS 21.10 has landed!

        Pop!_Pi Tech-Preview for Raspberry 4

        Tinkerers, this one’s for you! A tech preview of Pop!_OS 21.10 is now available on the Raspberry Pi, a mini computer for STEM learning and experimentation. We built Pop!_Pi for the Raspberry Pi 4 to gain experience building for ARM platforms. The Raspberry Pi 4 performed much better than we anticipated, so we decided to release it to the public.

        It’s a Tech-Preview because it doesn’t receive as much Quality Assurance focus as Pop!_OS for the desktop, but is nonetheless an excellent option for users. We plan to continue releasing Pop!_Pi with future Pop!_OS releases.

        Latest Hardware Support

        Pop!_OS 21.10 features the 5.15.5 kernel and latest NVIDIA driver. Pop!_OS has a new kernel policy whereby the latest kernels will be released once they’ve passed extensive quality assurance tests. This is the same release policy we’ve used for NVIDIA drivers.

        The System76 hardware lab contains a broad spectrum of chipsets, processors, and components to test for regressions prior to release so customers and users can be confident that new kernel releases will only improve their hardware performance and support.

        New, More Intuitive Refresh OS Feature

        Your system will now recognize when Pop!_OS is installed from the recovery partition and offer the Refresh OS option prior to unlocking an encrypted drive. This makes it easier to see when the Refresh OS option is available.

      • First Look at System76’s Pop!_Pi OS for Raspberry Pi 4

        That’s right, Pop!_OS Linux has been ported to Raspberry Pi devices, and is the first website to take the new Pop!_Pi 21.10 operating system for a spin on a Raspberry Pi 4 board with 8GB RAM. System76 informed me that Raspberry Pi 400 models are also supported.

        According to System76, Pop!_Pi was built for the Raspberry Pi 4 to help them gain experience building for ARM platforms, but the system performed so well that they decided to release it to the public.

      • Pop!_OS 21.10 is Here, Jumps Ahead to GNOME 40

        System76 has released Pop!_OS 21.10, its bespoke Linux distribution based on Ubuntu. So let’s take a quick look what’s new!

        For those of you unaware, Pop!_OS was born when Canonical, the company behind Ubuntu, abandoned the Unity desktop. The distro is developed by System76, a US computer manufacturer of Linux-based laptops, desktops and servers.

        Pop!_OS 21.10 is the latest version of the System76’s popular open-source desktop operating system that features some improvements and other mostly desktop alterations.

      • Pop OS 21.10 Introduces Mini Application Menu + Bumper Updates

        The Pop team officially released the POP OS 21.10. In this post, we wrap up the release highlights and give you download & upgrade details.

      • Pop!_OS 21.10 rolls out with new Application Library | GamingOnLinux

        System76 has rolled out Pop!_OS 21.10 today, the latest major upgrade to their Ubuntu-based operating system designed to be used by everyone - professionals and gamers alike. It comes with some absolutely massive improvements too and it really does look fantastic.

        The big user-facing feature is the new Application Library. Instead of getting a big full-screen wall of information and icons, you now get a smaller searchable window over your currently used workspace. It can be opened in a few ways too like the top bar, a 4-finger swipe right on the trackpad, or by using Super + A on the keyboard.

        With this change it gives a better workflow for multi-monitor users (hooray!) since it will go to the display that has your current mouse focus. The list is sorted alphabetically too making it more natural, you have the ability to drag and drop into folders for organisation and of course the search makes it quick and easy to find exactly what you want.

      • Pop!_OS 21.10 Released with New App Library Feature + More - OMG! Ubuntu!

        System76 have slipped in to their Santa suits to deliver Linux users an early festive treat: Pop!_OS 21.10.

        Yes, the latest version of their Ubuntu-based Linux distro is available to download. It includes a new Linux kernel, the bulk of GNOME 40, a new App Library feature (more on that in a mo) and refinements to its (handy) OS restore options.

        Notwithstanding a recent red-faced encounter with a tech YouTuber, Pop!_OS has proven a popular choice with Linux gamers since launching in 2017. Part of the reason is that this distro offers a newer Linux kernel and more recent graphics drivers than vanilla Ubuntu.

        But soon there’ll be an even greater distinction: System76 plans to build its own desktop environment! Having found that the direction of upstream GNOME is out of kilter with their needs they’re going it (sort of) alone.

      • Pop!_OS is Now Available for the Raspberry Pi 4 - OMG! Ubuntu!

        Pop!_OS is now available for the Raspberry Pi.

        The sweetly-named Pop!_Pi is available to download as a ‘tech preview’ alongside the latest Pop!_OS 21.10 release from System76.

        While Pop!_Pi is the first version of Pop!_OS to be available for Raspberry Pi devices it doesn’t support all Raspberry Pi Models. Instead, the Pop!_Pi tech preview caters to the ‘desktop class’ Raspberry Pi 4 board (which regular Ubuntu also supports). It requires the model with 4GB RAM or more.

        If you use Linux (whatever flavour) you’ll have no doubt heard of the Raspberry Pi even if you haven’t ever used one. The line of cheap mini-computers has been nothing short of a revolution, lowering the barrier to entry for tech across the world and throughout industry.

      • Pop!_OS 21.10 Introduces a New Application Library, GNOME 40, and a Refresh Install Option

        Pop!_OS is undoubtedly one of the best Linux distributions, also happens to be a popular recommendation currently for Linux newbies (and gamers).

        If you do not prefer non-LTS releases, you should stick to Pop!_OS 20.04 LTS. But, if you are looking for the latest and greatest update, Pop!_OS 21.10 is finally here for you to download!

        Not to forget, the Pop!_OS 21.10 release sets things in motion for a potential list of features that you can expect with Pop!_OS 22.04 LTS, April next year.

      • Five Linux distributions to resurrect an old laptop - TechStony

        It seems that Microsoft is making it difficult to run Windows 11 on a large number and variety of hardware, especially if it is not recent and does not meet certain requirements. Seeing this situation, that Windows 7 is officially “defunct” and that Windows 10 may not shine on those computers, we are going to publish a list of Five Linux Distros That Could Bring An Old Laptop To Life.

        Of course, when we talk about an old laptop, we are not referring to what some may be thinking. In this post we will focus on old 64-bit x86 computers, because those computers exist, although in a large part of the collective imagination it is not like that. More concretely, we will put the ground on the Intel Core 2 Duo, the generation of processors that together with the Core 2 Quad ended up standardizing the 64-bit x86 processors 15 years ago in the consumer market.

        The extremely long life that Windows XP enjoyed, together with the fact that applications compiled for 64-bit x86 did not begin to be standardized in Windows until approximately 2011-2012, ended up generating in the collective imagination the idea that the processors of this architecture has been with us for a few years.

        In fact, few remember the hype that arose around Battlefield 3 when Electronic Arts announced in 2011 that it would require Windows 7 64-bit as a system. At that time Windows XP was still widely used, which aroused the complaints of many users, but DICE and Electronic Arts remained firm and did well, because that was the beginning of a technological leap necessary for video games to take better advantage of the processors that They have been with us for years.

      • What’s New In Kubernetes v1.23?

        Kubernetes v1.23 is the last major release of 2021. The latest update to the leading container orchestration platform promotes 11 features to the stable channel, marking them as suitable for general use. Here’s what you need to know before you upgrade.


        While an “ephemeral” volume may initially sound strange, there are several use cases for this functionality. Volumes are often used to provide a Pod’s process with first-run config values that are only accessed once. In this scenario, an ephemeral Pod is ideal as it’ll be deleted when the Pod stops, instead of being reattached to future Pods that’ll never use the data. Another possible case is processes which cache large amounts of data but don’t need it to be persisted between individual Pod terminations.

      • Don't expect a new cut of Linux to ease your NYE hangovers

        The Register can at last reveal the answer to the question on everyone's lips: who would win a hypothetical fight between Santa Claus and Linus Torvalds?

        And the winner is … Santa! We have reached this decision based on Torvalds's regular state of the kernel post for this week, in which he rated the development process for version 5.16 of the Linux kernel as "fairly normal".

        "This rc5 is perhaps a bit bigger than usual, but it's not like it's breaking any records," Torvalds wrote. "I blame people trying to get stuff done before the holidays, and/or just random timing effects."

        Torvalds thinks the holidays will slow the release of this version of the kernel.

        "With the holidays coming up, things are probably going to slow down both on the development and testing front, and as a result I expect that I will also extend the rc series by another week," he added.

        That addition won't be because the extra rc is needed – although Torvalds left open the possibility of messes making it necessary – "but simply because nobody will want to open the next merge window immediately in the new year".

        • LLVM Working On "HIPSPV" So AMD HIP Code Can Turn Into SPIR-V And Run On OpenCL - Phoronix

          Upstreaming progress is being made on a new "HIPSPV" toolchain for AMD's HIP path so that SPIR-V kernels can be executed and ultimately allowing for execution by OpenCL drivers. This HIPSPV effort driven outside of AMD aims to be able to allow HIP code to work on other GPU drivers such as those from Intel.

          AMD's HIP is their C++ Runtime API and kernel language for portable applications on AMD and NVIDIA GPUs from a single source tree. HIP has been AMD's answer to NVIDIA's CUDA by aiming to make it easy to port CUDA code to run on AMD Radeon / Instinct hardware. With tools like their open-source HIPIFY they even aim to make it easy and automated as possible for converting CUDA sources to HIP.

        • Radeon RADV Lands Emulated ETC2 Support For Improving Android Support - Phoronix

          While the ETC2 texture compression standard is royalty-free and popular for OpenGL / GLES / Vulkan use, recent AMD Radeon GPUs and APUs have removed their native support for this alternative to the likes of ASTC and S3TC. But now in Mesa 22.0 there is emulated ETC2 support for the Radeon "RADV" Vulkan driver to in turn improve this open-source driver's Android support.

          As covered last week, RADV ETC2 emulation has been in the works with only the likes of AMD Stoney APUs and Vega/GFX9 featuring native ETC2 hardware support.

        • X.Org Server Hit By Its Latest Batch Of Security Vulnerabilities - Phoronix

        PeerTube 4.0 with channel customization, playlists search, custom instance homepage and more video filters is out!

        PeerTube is an open source piece of software that enables anyone to run their own tube site (like YouTube) very easily. All of the sites everyone runs can talk to each other, and people with accounts on one can interact with people on others. To put it short, PeerTube is a network of tube sites.

        PeerTube is decentralized by most useful definitions of the word. Anybody can run their own PeerTube instance, and the instances can follow (or “connect”) to each other to form a larger whole. This is not an option you have with YouTube.

        When you watch a video on PeerTube the data will come from the instance hosting the video, any other instance that follows that instance and has redundancy enabled and other people watching the video at the same time as you do.

        Now the PeerTube’s devs has finally released PeerTube 4.0. Let’s see what are the new features.

      • How to test if your Linux server is vulnerable to Log4j - TechRepublic

        This vulnerability has the highest CVSS score of 10.0, so you need to pay attention. One of the big problems is knowing if you're vulnerable. This is complicated by the many ways Log4j can be deployed. Are you using it as part of a Java project, is it rolled into a container, did you install it with your distribution package manager, and (if so) which log4j packages did you install? Or did you install it from source? Because of this, you might not even know if your server is vulnerable.

        Fortunately, for Linux servers, GitHub user, Rubo77 created a script that will check for for packages that include vulnerable Log4j instances. It's in beta, and it's not one 100%, but it's a great place to start. Understand, this script doesn't test for jar files that were packaged with applications, so do not consider it anything more than a launching point to start your forensics.

        I tested this script against a server that I knew had a vulnerable Log4j package installed, and it correctly tagged it. Here's how you can run that same script on your Linux servers to find out if you might be vulnerable.

        Bottles isn't exactly a new Linux application but it's one I had only heard about recently. It's been advancing a lot in the last year and it's really looking great. Unlike other manager applications including Lutris, GameHub and so on it has a singular purpose — Bottles is designed to give you the best possible experience when managing the Windows compatibility layer Wine.

        It includes a lot of options to allow you to easily tweak your installs with a few clicks of a button, which is exactly what I love about it. There's a few "runners" included which are various versions of Wine like their own Vaniglia, that has a few wine-staging patches and a newer updated theme and Lutris' Wine.

          KDE Gear 21.12 has recently appeared as the latest release of the suite of applications that follow the parent project’s schedule (others like Krita and the Calligra suite do not). As usual in an environment as lively as KDE, applications tend to receive major improvements and changes at each iteration, so we take the opportunity to dig deeper into Kdenlive, the non-linear video editor.

          Kdenlive is a well-known editor that little by little has made a place for itself in non-professional and even professional video editing that does not require the advanced possibilities offered by solutions such as DaVinci Resolve and Adobe Premiere. Within its segment, it is probably the most popular application among Linux users, although it also has a Windows user base. Its codebase is currently released under the GPLv3 license.

          Kdenlive 21.12 comes with important new features that will surely make the application take an important qualitative leap, since it has incorporated a tracking algorithm based on deep learning. In other words, it has included support based on artificial intelligence, thus, at least roughly, in the wake of OpenShot.

        • Impressions of Linux Mint & elementary OS

          In a recent post, I spoke about some things that Linux distros need to do better to accommodate end-users. I was reminded that there are some Linux distros which are, at least to some extent, following my recommended playbook, and have been re-evaluating two of them over the past couple of weeks: Linux Mint and elementary OS. I installed these on one of my laptops and used it as my daily driver for a day or two each.

          Both of these distributions are similar in a few ways. For one, both distros required zero printer configuration: it just worked. I was very impressed with this. Both distros are also based on Ubuntu, though with different levels of divergence from their base. Ubuntu is a reasonably good choice: it is very stable and mature, and commercially supported by Canonical.

          I started with elementary OS, which does exactly what I proposed in my earlier article: charge users for the OS.1 The last time I tried elementary, I was less than impressed, but they’ve been selling the OS for a while now so I hoped that with a consistent source of funding and a few years to improve they would have an opportunity to impress me. However, my overall impressions were mixed, and maybe even negative.

          The biggest, showstopping issue is a problem with their full disk encryption setup. I was thrilled to see first-class FDE support in the installer, but upon first boot, I was presented with a blank screen. It took me a while to figure out that a different TTY had cryptsetup running, waiting for me to enter the password. This is totally unacceptable, and no average user would have any clue what to do when presented with this. This should be a little GUI baked into the initramfs which prompts for your password on boot, and should be a regularly tested part of the installer before each elementary release ships.

          The elementary store was also disappointing, though I think there’s improvements on the horizon. The catalogue is very sparse, and would benefit a lot by sourcing packages from the underlying Ubuntu repositories as well. I think they’re planning on a first-class Flatpak integration in a future release, which should improve this situation. I also found the apps a bit too elementary, haha, in that they were lacking in a lot of important but infrequently used features. In general elementary is quite basic, though it is also very polished. Also, the default wallpaper depicts a big rock covered in bird shit, which I thought was kind of funny.

          There is a lot to like about elementary, though. The installer is really pleasant to use, and I really appreciated that it includes important accessibility features during the install process. The WiFi configuration is nice and easy, though it prompted me to set up online accounts before prompting me to set up WiFi. All of the apps are intuitive, consistently designed, and beautiful. I also noticed that long-running terminal processes I had in the background would pop-up a notification upon completion, which is a nice touch. Overall, it’s promising, but I had hoped for more. My suggestions to elementary are to consider that completeness is a kind of polish, to work on software distribution, and to offer first-class options for troubleshooting, documentation, and support within the OS.

          After 4 months of intensive work, here is the 2.0 version of Kaisen Linux, two years to the day after the release of the first alpha version! This new release is a major revision of the previous rolling versions!

          Detailled and significant changes:

          Numerous improvements and bug fixes make this the most stable release ever. That's partly why it is called 2.0, the numerous refactorings justified the version number change. Kaisen is now based on Debian Bookworm (Debian 12), also justifying the version number change.

          Among the most important things done on this new release, a complete overhaul of the menu with new, nicer and more modern icons, simplification of the menu and removal of about 15 launchers among the basic commands (such as mount and umount for example), new implementation of BTRFS snapshot tools, new tools dedicated to Cloud engineers!

          CentOS Stream 9 has been around for a while, but it was officially announced just a few days ago. I already tested some earlier snapshots and they had some rough edges. The current version installed without random crashes, has networking and runs smoothly. EPEL – the semi-official repository by Fedora maintainers – is already there, but practically empty, syslog-ng or it’s dependencies are not yet there. As someone asked about syslog-ng support, I had a first try at building it.

          I built syslog-ng for CentOS Stream 9 in the Copr build service. Many of the syslog-ng dependencies are not yet available, so I had to compile them myself. EPEL 9 is expected to have the latest Fedora versions, so I used those. I could not get MongoDB client libraries compiled, but the rest of the dependencies are there.

        • How open source is making diabetes more manageable

          For the average person, you go about your day without too much thought to what is happening within your body. For diabetics however, their entire day is built around monitoring the minute changes that could have serious health implications for them. In order to manage these changes, they need special tools that are designed to track as blood sugar levels rise and fall, produce insulin and time its delivery to maintain health. But what happens when the tools and systems don’t serve the people who need them?

          Premiering today, "Opening the Loop: Autonomy, Access, and Insulin"—the latest documentary in the Open Source Stories series from Red Hat—follows the growing DIY community of makers, patients and caregivers that are reshaping those systems to better match their needs. Their work happens in bedrooms, at kitchen tables, in conference rooms and at the lab bench. And it’s making life better for untold numbers of others.

          In the film we learn about the challenges type 1 diabetics and caregivers face as they identify the need for insulin, access and acquire it and actually inject it. These challenges stem from the use of closed-source solutions like off-the-shelf blood glucose monitors that only share data with certain devices, insulin pumps that communicate with some monitors, but not others, and issues with the insulin itself.

            I’m using an external keyboard (1) and mouse (2), but the laptop lid is usually still open for better cooling. That means the internal keyboard (3) and touchpad (4) – made of comfortable materials – are open to be used by a cat searching for warmth (7), in the obvious “every time” case that a normal non-heated nest (6) is not enough.

            The problem is, everything goes chaotic at that point in the default configuration. The solution is to have quick shortcuts in my Dash to Dock (8) to both disable (10) and enable (9) keyboard and touchpad at a very rapid pace.

            It is to be noted that I’m not disabling the touch screen (5) by default, because most of the time the cat is not leaning on it – there is also the added benefit that if one forgets about the internal keyboard and touchpad disabling and detaches the laptop from the USB-C monitor (11), there’s the possibility of using the touch screen and on-screen keyboard to type in the password and tap on the keyboard/touchpad enabling shortcut button again. If also touch screen was disabled, the only way would be to go back to an external keyboard or reboot.

      • Fixing a Tiny Corner of the Supply Chain €« bunnie's blog

        No product gets built without at least one good supply chain war story – especially true in these strange times. Before we get into the details of the story, I feel it’s worth understanding a bit more about the part that caused me so much trouble: what it does, and why it’s so special.


        It’s clearly a great part for a low-power mobile device like Precursor, which is why I designed it into the device. Unfortunately, there’s also no real substitute for it. Nobody else makes a MEMS oscillator of comparable quality, and as outlined above, this device is smaller and orders of magnitude lower power than an equivalent quartz crystal. It’s so power-efficient that in many chips it is less power to use this off-chip oscillator, than to use the built-in crystal oscillator to drive a passive crystal. For example, the STM32H7 HSE burns 450uA, whereas the SiT8021 runs at 160uA. To be fair, one also has to drive the pad input capacitance of the STM32, but even with that considered you’re probably around 250uA.

        To put it in customer-facing terms, if I were forced to substitute commonly available quartz oscillators for this part, the instant-on standby time of a Precursor device would be cut from a bit over 50 hours down to about 40 hours (standby current would go from 11mA up to 13mA).

        If this doesn’t make the part special enough, the fact that it’s an oscillator puts it in a special class with respect to electromagnetic compliance (EMC) regulations. These are the regulations that make sure that radios don’t interfere with each other, and like them or not, countries take them very seriously as trade barriers – by requiring expensive certifications, you’re able to eliminate the competition of small upstarts and cheap import equipment on “radio safety” grounds. Because the quality of radio signals depend directly upon the quality of the oscillator used to derive them, the regulations (quite reasonably) disallow substitutions of oscillators without re-certification. Thus, even if I wanted to take the hit on standby time and substitute the part, I’d have to go through the entire certification process again, at a cost of several thousand dollars and some weeks of additional delay.

        A highly anticipated clinical trial in eight sub-Saharan countries is the first to specifically evaluate the efficacy of a COVID-19 vaccine in people living with HIV, including those with poorly controlled infections. It also is the first study to evaluate the efficacy of vaccines – in this case, Moderna mRNA-1273 – against the omicron variant of SARS-CoV-2, the virus that causes COVID-19.

        In addition to examining the efficacy of COVID-19 mRNA vaccines in people living with HIV, the study investigators seek to identify the optimal regimen for this population and how it might vary based on whether an individual has previously had COVID-19 or not.

        The trial will be conducted in East and Southern Africa – regions of the world that have been highly impacted by HIV. It is expected to enroll about 14,000 volunteers at 54 clinical research sites in South Africa, Botswana, Zimbabwe, Eswatini, Malawi, Zambia, Uganda and Kenya, where adult HIV prevalence ranges from 4.5% to 27%.


        The trial is sponsored by the SAMRC and funded by the U.S. government and supported by the National Institute of Allergy and Infectious Diseases (NIAID) within the National Institutes of Health. Funding originates from the Department of Health and Human Services (HHS) through the Countermeasures Acceleration Group (CAG).

              The Log4j bug, an unauthenticated remote code execution flaw (CVE-2021-44228) in Apache's open-source Log4j Java-based logging library, is particularly serious and far-reaching because exploitation is not difficult and the software is widely used and buried deep within many programs.

              Annoyance with the handful of project maintainers for failing to catch the bug prompted one, developer Volkan Yazici, to voice indignation about all the people bashing the maintainers for their unpaid, volunteer labor without offering any financial support or contributed code fixes.

              Log4Shell is a Remote Code Execution Class vulnerability denoted as CVE-2021-44228 disclosed as an exploit that affects millions of servers that run Java applications, or particularly the open-source Apache Log4j library.

              If you are curious, a wide range of applications/servers and digital systems across the internet use Log4j for logging purposes. Even the back-end systems used by Steam, Minecraft, Cloudflare, and iCloud were found vulnerable.

              Why is it one of the most significant vulnerabilities in recent times? Let me tell you more about it.

            • The Log4j bug exposes a bigger issue: Open-source funding (Updated)

              While you were watching the F1 title decider between Max Verstappen and Lewis Hamilton or excited for the Succession finale, companies running the internet were scared shitless.

              You might not have noticed it because services like Twitter, Facebook, Gmail, and smaller ones all stayed up. But a bug in an open-source tech called Log4j was (and still is) causing panic amongst the infosec community across the world.

              While the bug has affected billions of devices, and companies are scrambling to apply fixes, the open-source community has a raging debate going on about funding volunteers that maintain projects like Log4j.

            • Log4j Bug Highlights Open Source Funding Issues

              A critical bug in a bit of open source tech called Log4j has been causing panic in the infosec community, reports Ivan Mehta. And, while major companies are scrambling to apply fixes, “the open source community has a raging debate going on about funding volunteers that maintain projects like Log4j.”

              Many large corporations depend heavily on free and open source software projects such as Log4j, Mehta notes; however, project contributors and maintainers often receive only a small amount of financial support through GitHub or Patreon.

      • Measuring Air Quality Using Mobile Sensors For The Masses | Hackaday

        Poor air quality is a major problem for city dwellers the world over. Dust, smoke, particles and noxious gases from vehicles, industry and agriculture makes many megacities downright hazardous to live in. Pinpointing the source of pollution and developing strategies for mitigation requires accurate data on pollutant levels, but obtaining these numbers is not always easy.

        Enter CanAirIO, a citizen science project that aims to gather air quality data from around the world by putting sensors into the hands of as many people as possible. Its team has developed two different sensor nodes for this purpose: an indoor one that can measure CO2, and a mobile one that can measure particulate matter (PM) levels. Both versions are powered by an ESP32 microcontroller that reads out the air quality sensors and connects to the Internet using WiFi or BlueTooth. The data can then be shared online to create detailed maps showing local variations in air quality.

      • Victories in the DSA vote: IMCO Committee puts people’s rights before corporate interest - Access Now

        Access Now welcomes important victories green-lighted by the Committee for Internal Market and Consumer Protection (IMCO) in yesterday’s Digital Services Act (DSA) vote, indicating concrete steps towards the further protection of freedom of expression and opinion online across the European Union. Since the beginning of negotiations, Access Now has fought side-by-side with partner organisations to protect freedom of expression and opinion online, while countering short-sighted proposals that would only bolster the undesirable status quo in the content governance in defiance of fundamental rights standards.

        “We see victories in yesterday’s DSA vote. The fact that the IMCO Committee did not cave in to corporate interest, and centred people’s empowerment and their fundamental rights in the negotiations is an encouraging sign for the next stages,” said Eliska Pirkova, Europe Policy Analyst and the Global Freedom of Expression Lead at Access Now. “But there is still room for improvement, and the fight for a truly human rights centric model of platform governance will continue throughout the trilogue negotiations, where we must fix prevailing issues in the text. Yesterday’s vote is a reason to celebrate, but there is more hard work to ensure the protection of free expression and opinion online on the horizon.”
