      • Linux 5.17 Mainlines Support For More Obsolete MIPS-Based Wireless Routers – Phoronix

        While the MIPS CPU architecture itself is at the end of the road, kernel developers still are busy with MIPS considering the Loongson hardware that is popular in China and lots of older MIPS hardware out there lacking mainline Linux kernel support. For Linux 5.17 several more older, consumer-grade network routers are seeing mainline support.

        With MIPS-specific code for Linux 5.17 the Loongson 2K1000 reset driver has been merged, support for the TX4939 SoC and RBTX4938/RBTX4939 boards removed with no known users remaining, MIPS support for the Broadcom BRCMSTB PCIe controller, and other fixes and clean-ups. Plus there is support for more MIPS-based devices (routers) using the Broadcom BCM47xx MIPS-based SoCs.

      • Intel’s Linux Graphics Driver Continues With Multi-Tile Preparations – Phoronix

        In addition to Intel’s open-source Linux graphics driver developers being quite busy preparing for upcoming Intel Arc “Alchemist” (DG2) graphics cards on the consumer side, they have concurrently been preparing for Xe HP “Ponte Vecchio” hardware too. One of the big undertakings on that side from the driver perspective is bringing up multiple tiles.

        For Ponte Vecchio’s multi-tile / chiplet design, Linux driver work for multi-tile support has been going on for months. The driver needs to adapt to support multiple GT instances and the multiple memory regions off a single PCI Express device.

      • Ubuntu 22.04 LTS Planning To Stick With Linux 5.15 By Default – Phoronix

        It turns out Ubuntu 22.04 LTS is planning to use the Linux 5.15 kernel as its default kernel. It makes sense in that Linux 5.15 is also a long-term support kernel, but unfortunate in that Ubuntu LTS releases haven’t always used LTS kernel versions and v5.15 will be a half-year old already by the time the “Jammy Jellyfish” ships in April. This is a choice particularly unfortunate for those with recent hardware but at least there is the Ubuntu Mainline Kernel PPA and other non-default options available.

      • Ubuntu 22.04 LTS Will Use Linux 5.15 Kernel

        Ubuntu 22.04 LTS will come with the Linux 5.15 kernel by default.

        That’s the current plan according to Canonical’s Sebastien Bacher, who says “the plan is to use 5.15 for the LTS but the oem and hwe variants will get 5.17 as some point”.

    • Applications

      • Libre Arts – Streamlining Inkscape for the masses

        It’s not a heavily guarded secret that I have an undying love for Inkscape. For me, it’s one of those applications I’m really excited to use every time I have some silly need for a vector graphics editor. Which is why everyone actively involved with the project is my personal hero, and I’m only happy to chat with them every once in a while about how the project is doing.

        This time, I spoke to Chris Rogers (Vectors team, i.e. PR and communication), Tavmjong Bah (developer), Martin Owens (developer), and Adam Belis (UX guy).

        Q: So, first off, I love a lot of things going on with Inkscape lately. There was a, well, not a moment, but quite a long period of time, actually, when I was a bit scared for the project. Long dev cycles, not enough developers etc. Things seem to be so much better these days. What would you attribute it to? What did you have to change?

        CRogers: better organisation internally helped. A move to RocketChat and Gitlab to track issues and multiple groups for different parts of the project seem to really have helped. Also, sharing successes and mutual respect and gratitude creates motivation, and it’s easier to do that with organised chat and group structures.

      • How To Setup and Limit Hotspot Data on Your Android Device

        Suppose you have an emergency situation and need an internet connection badly, but you don’t have any cellular data or Wi-Fi connection nearby. And noticed that some of your friends or colleagues are with you at this moment who are having cellular data on their phones. The thing is, you have to use your Android device to complete the task. So what to do now? Turn on your friends’ or colleagues phones’ cellular data and hotspot and Wi-Fi of your phone. Just connect your device to their hotspot. The setup and limit hotspot data procedure on your Android is as easy as pie.

        Similarly, you can set up your hotspot on your Android device and also limit the users according to your requirements. Normally, if you’re giving your cellular data to another user through a hotspot, then the rate of data consumption is huge.

        As a result, you need to limit your users at a time, though there’s an option called Unlimited users that will be in the hotspot setting. Let’s start with the setup and limit hotspot data on your Android easily.

      • 6 Reasons Why You Should Try the Lightweight Xfce Desktop

        Xfce is a rather humble desktop environment. It has been around for decades, but it has existed largely in GNOME’s shadow as a more lightweight option that just so happens to also be based on GTK. Fewer developers work on Xfce and hence, there are fewer apps made with Xfce in mind.

        Yet year after year, people continue to use Xfce. It receives updates, and numerous Linux-based operating systems ship Xfce as the default interface.

        So, despite the other options available, why might you want to use Xfce?

        • Flowblade video editor now in EasyOS

          Easy 3.2 has LiVES video editor; however, it still has bugs. The developer is working on it, but in the meantime I do need something that works in Easy. So, I looked at the alternatives, and eventually settled on Flowblade.

          Flowblade is written in python, and I had initially rejected it as it requires python2. It also has two dependencies that I really didn’t want to include, ‘frei0r’ and ‘gmic’, as I thought the number of dependencies was getting a bit too high. Besides, gmic seems very similar to ‘imagemagick’ that is already in Easy and required by ‘lives’ and ‘obs’.

        The extra processing power in this case comes from a Raspberry Pi Pico which is small enough to easily fit inside of a donor NES case and also powerful enough to handle the VGA directly. For video data input, the Pico is connected to the video pins on the Game Boy’s main board through a level shifter. The main board is also connected to a second Pico which handles the controller input from an NES controller. Some fancy conversion needed to be done at this point because although the controller layouts are very similar, they are handles by the respective consoles completely differently.

It’s foreign to people coming from writing normal Rust code trying to write GObject-based code, and it’s foreign to many people used to writing GObject-based code in other languages (e.g. C, Python, JavaScript, and Vala). Over the years I’ve explained it a few times, and I figure now that I should write a blog post that I can point people to describing what the clone!() macro is, what it does, and why we need it in detail.

          • Qt 6.3 Alpha released

            You can find initial list of new features in the Qt 6.3.0 from What’s New in Qt 6.3 documentation. But please note the documentation is still under construction and will be updated until we are ready for the final release.

            As usual, you can add the Qt 6.3 Alpha to the existing online installation by using the maintenance tool. Or you can do a clean installation by using the Qt Online Installer. Qt 6.3 Alpha source packages can be downloaded from the Qt Account portal and the download.qt.io as well.

          • Qt 6.3 Alpha Released With New Qt Quick Compiler For Commercial Customers – Phoronix

            The Qt Company just announced Qt 6.3 Alpha as the first formal test release for this next Qt6 toolkit update. The Qt Company also lifted the lid on their new Qt Quick Compiler where they are aiming for QML to run at “a speed close to native” for that interpreted language.

            Qt 6.3 has been working on a new “Qt Language Server” module, there are a number of new functions in the Qt Core module, Qt Quick has added a MessageDialog that will provide a native dialog message box on supported platforms, “qmltc” as the new QML type compiler, the Qt Wayland Compositor module adds a Qt Shell that supports all windowing system features handled by Qt, Qt Wayland can now support creating custom shell extensions, support for Wayland’s Presentation Time protocol, and a variety of other additions.

          • The new Qt Quick Compiler – get QML to run at a speed close to native

            As most of you know, QML is an interpreted language. The flexibility of any interpreted language always comes with a potential decrease in performance. As we are very convinced of many other potentials of QML, we strive to reduce – if not to completely eliminate – this unpleasant potential. We implemented changes in the last Qt5 releases and especially in Qt6 helping to take a significant step towards our long term goal: make QML run at a speed close to native. This blog post explains what is new. The upcoming two blog post will elaborate the technology and its development history.

            In this tutorial, we will show you how to install Apache NetBeans on Fedora 35. For those of you who didn’t know, The NetBeans (also known as Apache Netbeans) is an open-source and award-winning IDE (integrated development environment) application for Windows, Linux, and Mac. It offers excellent debugging capabilities, coding, plugins, and extensions with multiple out-of-the-box features.

            This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Apache NetBeans IDE on a Fedora 35.

    • Rapid-Reload Vacuum Cannon Totally Demolishes Those Veggies | Hackaday

      [NightHawkInLight] has been developing his design for a vacuum canon for a while now, so it seems fitting to drop in check out the progress. The idea is pretty straightforward, take a long rigid tube, insert a close fitting piston, magnetically attached to a projectile, and stopper the open end with something easily destroyed. The piston needs to be pulled into the tube with some force, to pull a vacuum against the stopper. The interesting bit happens next, when the piston exits the other end of the tube, with the vacuum at its maximum, there is a sudden inrush of air. Apparently this inrush of supersonic velocity, and the momentum of the mass of air is sufficient to eject the projectile at considerable velocity, smashing through the plug and demolishing the target. So long as the target is of the soft and squishy variety anyway.

      • This DIY Microscope Design Is All Wet | Hackaday

        [Robert Murray-Smith] wanted to recreate how some ancient microscopes worked: with a drop of water as a lens. The idea is that the meniscus of a drop of water will work as a lens. This works because of surface tension and by controlling the attraction of the water to the surface, you can actually form convex and concave surfaces.

        What’s interesting is that this doesn’t require a lot of equipment. Some plastic, a hole punch, some pens, a flashlight, and some other odds and ends. Then it’s just a matter of grabbing some puddle water and examining the critters inside. Of course, with a single lens, these are more properly magnifying glasses. Some claim that people in China built such instruments thousands of years ago. [Robert] mentions [Antonie van Leeuwenhoek] as the father of the microscope, although he wasn’t the first to build such a device. He did create amazing glass lenses using a method he kept secret but has been worked out using modern science.

Unlike a gas-based car, where you can always find a gas station when you need to top off, there’s nothing like enough electrical charging stations. One big reason for this is that there’s no standardization to speak of behind those chargers. The Linux Foundation (LF) plans on changing this with the new LF Energy EVerest project.

          • Google says open source software should be more secure • The Register

            In conjunction with a White House meeting on Thursday at which technology companies discussed the security of open source software, Google proposed three initiatives to strengthen national cybersecurity.

            The meeting was arranged last month by US national security adviser Jake Sullivan, amid the scramble to fix the Log4j vulnerabilities that occupied far too many people over the holidays. Sullivan asked invited firms – a group that included Amazon, Apple, Google, IBM, Microsoft, and Oracle – to share ideas on how the security of open source projects might be improved.

            Google chief legal officer Kent Walker in a blog post said that just as the government and industry have worked to shore up shoddy legacy systems and software, the Log4j repair process – still ongoing – has demonstrated that open source software needs the same attention as critical infrastructure.

          • This Week In Security: NPM Vandalism, Simulating Reboots, And More | Hackaday

            We’ve covered quite a few stories about malware sneaking into the NPN and other JavaScript repositories. This is a bit different. This time, a JS programmer vandalized his own packages. It’s not even malware, perhaps we should call it protestware? The two packages, colors and faker are both popular, with a combined weekly download of nearly 23 million. Their author, [Marak] added a breaking update to each of them. These libraries now print a header of LIBERTY LIBERTY LIBERTY, and then either random characters, or very poor ASCII art. It’s been confirmed that this wasn’t an outside attacker, but [Marak] breaking his own projects on purpose. Why?

            It seems like this story starts back in late 2020, when [Marak] lost quite a bit in a fire, and had to ask for money on Twitter. Two weeks later, he tweeted that billions were being made off open source devs’ work, citing a FAANG leak. FAANG is a reference to the big five American tech companies: Facebook, Apple, Amazon, Netflix, and Google. The same day, he opened an issue on Github for faker.js, throwing down an ultimatum: “Take this as an opportunity to send me a six figure yearly contract or fork the project and have someone else work on it.”

              The mobile phones of dozens of journalists and activists in El Salvador have been hacked since at least early 2020 and implanted with Israeli-made Pegasus spyware typically available only to governments and law enforcement, according to a new report by a watchdog group.

              The University of Toronto’s Citizen Lab said on Wednesday it had identified an operator of the spyware working exclusively in El Salvador and targeting journalists and activists, many of whom were investigating alleged state corruption.

              While the researchers could not conclusively determine the hacks came from El Salvador’s government, the report said “the strong country-specific focus of the infections suggests that this is very likely”.

            • NSO spyware found targeting journalists and NGOs in El Salvador | ZDNet

              The University of Toronto’s Citizen Lab along with Access Now have found the Pegasus spyware developed by the now-sanctioned NSO Group was used to target journalists and non-government organisations operating in El Salvador.

              In total, the investigation found 35 individuals were targeted across 37 devices, with Citizen Lab having a high degree of confidence that data was exfiltrated from devices belonging to 16 targets.
