  • Fair Code vs Open Source, Which Wins The Future?

    When developers release their software as open source, they are also giving a by-definition right to every company in the world to commercially use their software without having to obtain a license or share some profits with them. And this caused some problems in the open source world few years ago. For example, Amazon took the MongoDB source code (An open source database system), changed its name and then provided it as a SaaS (Software-as-a-Service) on its AWS platform, and then charged people money to use it. MongoDB developers were angered since they literally got nothing back from Amazon although they are the original creators of 100% of the code.

    This adds some sustainability problems to open source projects, as anybody and any company can just take the code and then reuse it commercially without giving anything back to the original developers. The original developers may starve and the project may stop, and there would be no obligation by anyone to commercially pay them.

    Fair code initiative arose from this context; To prevent anyone from using the software commercially without contacting the original software authors first, making it under the umbrella of what’s known as source-available models.

  • How to Convert a Project to REUSE Compatible License Statements?

    This blog post provides a step-by-step example about how the conversion of a project to REUSE compatible license statements is done in practice. For my setup, I have a readily configured kdesrc-build environment.

    First, I get out the most recent source code if the project I want to convert. For this tutorial, I use KTurtle, which is a nice and small application from KDE Education with just about 200 files.

  • John Cook: Descartes and Toolz

    I was looking recently at the Python module toolz, a collection of convenience functions. A lot of these functions don’t do that much. They don’t save you much code, but they do make your code more readable by making it more declarative. You may not realize need them until you see them.

    For example, there is a function partitionby that breaks up a sequence at the points where a given function’s value changes. I’m pretty sure that function would have improved some code I’ve written recently, making it more declarative than procedural, but I can’t remember what that was.

    Although I can’t think of my previous example, I can think of a new one, and that is Descartes’ rule of signs.

  • How big data forced the hunt for extraterrestrial intelligence to evolve

    Interest in SETI can be used to bring the public into science as well. A recent collaboration between the SETI Institute and the open-source software project GNU Radio aims to give people the opportunity to learn about radio engineering, digital signal processing, and radio astronomy. By purchasing a dongle for around $25, members of the public can digitize analog radio signals and process signals on their computers.


  • Getting credit: Taking your place in a meritocracy

    Dealing with either of those incredibly frustrating situations without appearing petty is difficult. But getting credit for your ideas and work is critical in today's organizational environments, especially those that aspire to be well-functioning meritocracies. Promotions, bonuses, and other forms of recognition (such as the opportunity to lead the project you proposed) are all generally based on performance. If people don't know you contributed, you'll likely be continually overlooked.

Regressions in GNU/Linux Evolution

  • When "progress" is backwards

    Lately I see many developments in the linux FOSS world that sell themselves as progress, but are actually hugely annoying and counter-productive. Counter-productive to a point where they actually cause major regressions, costs, and as in the case of GTK+3 ruin user experience and the possibility that we'll ever enjoy "The year of the Linux desktop". [...] We live in an era where in the FOSS world one constantly has to relearn things, switch to new, supposedly "better", but more bloated solutions, and is generally left with the impression that someone is pulling the rug from below one's feet. Many of the key changes in this area have been rammed through by a small set of decision makers, often closely related to Red Hat/Gnome/ We're buying this "progress" at a high cost, and one can't avoid asking oneself whether there's more to the story than meets the eye. Never forget, Red Hat and Microsoft (TM) are partners and might even have the same shareholders.

Graphics: Vulkan, Intel and AMD

  • NVIDIA Ships Vulkan Driver Beta With Fragment Shading Rate Control - Phoronix

    This week's Vulkan 1.2.158 spec release brought the fragment shading rate extension to control the rate at which fragments are shaded on a per-draw, per-primitive, or per-region basis. This can be useful similar to OpenGL and Direct3D support for helping to allow different, less important areas of the screen be shaded less than areas requiring greater detail/focus. NVIDIA on Tuesday released the 455.26.02 Linux driver (and 457.00 version for Windows) that adds this fragment shading rate extension.

  • Intel Begins Adding Alder Lake Graphics Support To Their Linux Driver - Phoronix

    Intel has begun adding support for Alderlake-S to their open-source Linux kernel graphics driver. An initial set of 18 patches amounting to just around 300 lines of new kernel code was sent out today for beginning the hardware enablement work on Alderlake-S from the graphics side. Yes, it's only a few hundred lines of new driver code due to Alder Lake leveraging the existing Gen12/Tigerlake support. The Alder Lake driver patches similarly re-use some of the same workarounds and changes as set for the 14nm Rocket Lake processors with Gen12 graphics coming out in Q1.

  • AMD Linux Driver Preparing For A Navi "Blockchain" Graphics Card - Phoronix

    While all eyes are on the AMD Radeon RX 6000 "Big Navi" graphics cards set to be announced next week, it also looks like AMD is preparing for a Navi 1x "Blockchain" graphics card offering given the latest work in their open-source Linux driver. Patches posted today provide support for a new Navi graphics card referred to as the "navi10 blockchain SKU." The Navi 10 part has a device ID of 0x731E. From the AMDGPU Linux kernel driver perspective, the only difference from the existing Navi 10 GPU support is these patches disable the Display Core Next (DCN) and Video Core Next (VCN) support with this new SKU not having any display support.
