  • Civil Infrastructure Platform Takes Open Source to an Industrial Scale

    One of the less discussed uses for open source software is actually in the role that it plays for industrial-scale hardware. Whereas power plants, factories, and other large infrastructure projects were once ruled over nearly entirely by operational technology (OT) control systems, in recent years, information technology — built on open source software — has been making its way onto the scene in an increasingly significant way.

    Additionally, another surprising fact is that the this push to use open source in complex hardware operations has been embraced by industry leaders. One company helping to lead the charge is Siemens, one of the world’s largest producers of hardware devices, Siemens. Siemens plays an active role in advancing open source in the industrial space, with a focus on making open source security a priority for development, in part through their involvement in the Civil Infrastructure Platform (CIP) initiative.

    Final Directive is a pretty good shooter that released for Linux back in February and we have a copy to give away.

    And we’re going to release the Mac and Linux versions as soon as we can.

  • [Krita] Interview with Runend

    I have tried some of the features, especially the brush engine, UI/UX, layering, animation tools, I love all of them! And of course it’s free and open source.

  • Kdenlive in Paris

    The next weeks will be exciting for Kdenlive! First, there is a Kdenlive sprint, that will take place in Paris from the 25th to the 29th of april. We are very proud to be hosted at the Carrefour Numérique in the Cité des Sciences, Paris.

  • Free software log (March 2018)

    I did get a few software releases out this month, although not as much as I'd planned and I still have a lot of new releases pending that are waiting for me to have a bit more free time.

    control-archive got a 1.8.0 release, which catches up from accumulated changes over the past year plus and falls back to GnuPG v1 for signature processing. One of the projects that I'd like to find time for is redoing all of my scattered code for making and checking Usenet control messages.

  • Update desktop components for released version
  • Building my ideal router for $50

    After my Asus N66U kicked the bucket, I considered a few options: another all-in-one router, upgrade to something like an EdgeRouter, or brew something custom. When I read the Ars Technica article espousing the virtues of building your own router, that pretty much settled it: DIY it is.

    I’ve got somewhat of a psychological complex when it comes to rolling my own over-engineered solutions, but I did set some general goals: the end result should be cheap, low-power, well-supported by Linux, and extensible. Incidentally, ARM boards fit many of these requirements, and some like the Raspberry Pi have stirred up so much community activity that there’s great support for the ARM platform, even though it may feel foreign from x86.

    I’ve managed to cobble together a device that is not only dirt cheap for what it does, but is extremely capable in its own right. If you have any interest in building your own home router, I’ll demonstrate here that doing so is not only feasible, but relatively easy to do and offers a huge amount of utility - from traffic shaping, to netflow monitoring, to dynamic DNS.

    I built it using the espressobin, Arch Linux Arm, and Shorewall.

Graphics: XRGEARS and Arcan's Latest

  • XRGEARS: Infamous "Gears" Now On VR Headsets With OpenHMD, Vulkan
    Well, the virtual reality (VR) demo scene is now complete with having glxgears-inspired gears and Utah teapot rendering on VR head mounted displays with the new XRGEARS. Kidding aside about the gears and teapot, XRGEARS is a nifty new open-source project with real value by Collabora developer Lubosz Sarnecki. XRGEARS is a standalone VR demo application built using the OpenHMD initiative for tracking and Vulkan for rendering. XRGEARS supports both Wayland and X11 environments or even running off KMS itself. This code also makes use of VK_EXT_direct_mode_display with DRM leasing.
  • Arcan versus Xorg – Approaching Feature Parity
    This is the first article out of three in a series where I will go through what I consider to be the relevant Xorg feature set, and compare it, point by point, to how the corresponding solution or category works in Arcan. This article will solely focus on the Display Server set of features and how they relate to Xorg features, The second article will cover the features that are currently missing (e.g. network transparency) when they have been accounted for. The third article will cover the features that are already present in Arcan (and there are quite a few of those) but does not exist in Xorg.
  • Arcan Display Server Is Nearing Feature Parity With The X.Org Server
    The Arcan display server, which started off years ago sounding like a novelty with being a display server built off a game engine in part and other interesting features, is nearing feature parity with the X.Org Server. While most hobbyist display server projects have failed, Arcan has continued advancing and with an interesting feature set. Recently they have even been working on a virtual reality desktop and an interesting desktop in general. Arcan is getting close to being able to offering the same functionality as a traditional X.Org Server. If you are interested in a lengthy technical read about the differences between Arcan and X.Org, the Arcan developers themselves did some comparing and contrasting when it comes to the display support, windowing, input, font management, synchronization, and other areas.

CoC/Systemd Supremacy Over Linux Kernel

  • New Linux Code of Conduct Revisions: CoC Committee Added Plus Interpretation & Mediator
    The Linux Code of Conduct introduced last month that ended up being quite contentious will see some revisions just ahead of the Linux 4.19 stable kernel release. Greg Kroah-Hartman has outlined the planned changes as well as a new Code of Conduct Interpretation document. In the weeks since the Linux kernel CoC was merged, various patches were proposed but none merged yet. It turns out Greg KH was working in private with various kernel maintainers/developers on addressing their feedback and trying to come up with solutions to the contentious issues in private.
  • Some kernel code-of-conduct refinements
    Greg Kroah-Hartman has posted a series of patches making some changes around the newly adopted code of conduct. In particular, it adds a new document describing how the code is to be interpreted in the kernel community.
  • Systemd Adds Feature To Fallback Automatically To Older Kernels On Failure
    Systemd's latest feature is the concept of "boot counting" that will track kernel boot attempts and failures as part of an automatic boot assessment. Ultimately this is to provide automatic fallback to older kernels should a newer kernel be consistently failing. The feature was crafted over the past few months by Lennart Poettering himself to provide a way when making use of systemd-boot on UEFI systems it can automatically fallback to an older kernel if a newer kernel is consistently causing problems. This is treated as an add-on to the Boot Loader Specification. The systemd boot assessment is designed that it could also be used by non-UEFI systems and other boot platforms.

ODROID 'Hacker Board'

  • ODROID Rolling Out New Intel-Powered Single Board Computer After Trying With Ryzen
    While ODROID is most known for their various ARM single board computers (SBCs), some of which offer impressive specs, they have dabbled in x86 SBCs and on Friday announced the Intel-powered ODROID-H2. In the announcement they mentioned as well they were exploring an AMD Ryzen 5 2500U powered SBC computer, which offered fast performance but the price ended up being prohibitive. After the falling out with Ryzen over those cost concerns, they decided to go ahead with an Intel Geminilake SoC. Geminilake is slower than their proposed Ryzen board, but the price was reasonable and it ends up still being much faster than ODROID's earlier Apollolake SBC.
  • Odroid-H2 is world’s first Gemini Lake hacker board
    Hardkernel unveiled the Odroid-H2, the first hacker board with an Intel Gemini Lake SoC. The Ubuntu 18.10 driven SBC ships with 2x SATA 3.0, 2x GbE, HDMI and DP, 4x USB, and an M.2 slot for NVMe. When the Odroid-H2 goes on sale in November at a price that will be “higher than $100,” Hardkernel will join a small group of vendors that have launched a community backed x86-based SBC. This first open spec hacker board built around Intel’s new Gemini Lake SoC — and one of the first Gemini Lake SBCs of any kind — follows earlier Arm-based Odroid winners such as the Odroid-C2 Raspberry Pi pseudo clone and the octa-core Odroid-XU4.
