Wayland in 3.12, and beyond

Filed under
Graphics/Benchmarks

Our dedication towards Wayland has pushed us to build a cleaner architecture overall. What used to be a proliferation of X-specific video and input drivers is mostly culminating in centralized, standardized code. For input, we have libinput, which we’re using from Weston, mutter, and Xorg as well. What used to be a collection of chipset-specific video plugins for doing accelerated rendering have now been replaced by glamor, a credible chipset-independent acceleration architecture. What used to be large monolithic components heavily tied to Xorg and the Xorg input and video architectures have now been split out into separate, easily-reusable libraries with separate, easily-maintainable codebases. New, experimental features can be prototyped faster than ever before.

Graphics/Benchmarks
Linux

While NVIDIA will be dropping support soon for GeForce 8 through GeForce 300 series graphics hardware from their mainline graphics driver, they are committing to supporting these older graphics processors for another five years. The support will include new Linux kernel and X.Org Server updates along with critical bug-fixes.

Intel Pushes XenGT For GPU Access To Virtual Machines

Filed under
Graphics/Benchmarks

XenGT is designed just not for 3D graphics acceleration within guest instances but also for media acceleration and GPGPU compute acceleration. There's use-cases for XenGT within cloud computing, data centers, rich virtual clients, multi-screen infotainment, and other areas. With other Xen GPU pass-through solutions there is no ability for both the host and guest operating systems to each access the same GPU simultaneously but they must be independently assigned at this time as there isn't a guest virtual GPU driver as in the case of VMware SVGA2 or VirtualBox Chromium. With Intel's XenGT solution, however, there is sharing support -- multiple VMs can access the same graphics processor due to its full virtualization. XenGT is pushed as offering performance, features, and sharing capabilities.

Initial XWayland Support Looks To Land In X.Org Server 1.16

Filed under
Graphics/Benchmarks

Originally XWayland served as an X.Org module by which modified DDX hardware drivers could be loaded on the system so they could offer their 2D support. However, given the advancements of GLAMOR, that is being used instead so we can have one unified XWayland DDX without the need for having patched drivers for hardware support and should work on just about any platform that has OpenGL support. GLAMOR tends to still be slower than the hand-written 2D paths in the xf86-video-ati and xf86-video-intel DDX, but there's still a lot of optimizations and code rewrites taking place of the code now that it's moved from being a standalone library to living within the X.Org Server.

Nvidia adds Linux support for GK20A GPU

Graphics/Benchmarks
Linux

Linux creator Linus Torvalds criticized Nvidia in 2012 at Aalto Talk as “the single worst company we have ever dealt with.” Along with him many other members of the open source community previously criticized Nvidia’s proprietary hardware and software, which made open source alternatives difficult.

Welcome To The (Ubuntu) Bionic Age: Nautilus, a LTS and desktop icons

If you are following closely the news of various tech websites, one of the latest hot topic in the community was about Nautilus removing desktop icons. Let’s try to clarify some points to ensure the various discussions around it have enough background information and not reacting on emotions only as it could be seen lately. You will have both downstream (mine) and upstream (Carlos) perspectives here. Read more

Programming: Perl, JavaScript, Ick, PowerFake, pylint-django, nbdkit filters

  • An Open Letter to the Perl Community

    Some consider Perl 6 to be a sister language to Perl 5. Personally, I consider Perl 6 more of a genetically engineered daughter language with the best genes from many parents. A daughter with a difficult childhood, in which she alienated many, who is now getting out of puberty into early adulthood. But I digress.

  • Long Live Perl 5!

    While not mentioned in the original Letter, a frequent theme in the comments was that Perl 6 should be renamed, as the name is inaccurate or is damaging.

    This is the topic on which I wrote more than once and those who have been following closely know that, yes, many (but by no means all) in the Perl 6 community acknowledge the name is detrimental to both Perl 6 and Perl 5 projects.

    This is why with a nod of approval from Larry we're moving to create an alias to Perl 6 name during 6.d language release, to be available for marketing in areas where "Perl 6" is not a desirable name.

  • JavaScript Trends for 2018
    Trying to bet on how many new JavaScript frameworks will be released each month, is, the best software engineer’s game in the past 5 years.
  • Ick: a continuous integration system
    TL;DR: Ick is a continuous integration or CI system. See http://ick.liw.fi/ for more information.
  • Introducing PowerFake for C++
    PowerFake is a new mini-framework/tool to make it possible to fake/mock free functions and static & non-virtual member functions in C++. It requires no change to the code under test, but it might need some structural changes, like moving some parts of the code to a different .cpp file; or making inline functions non-inline when built for testing. It is useful for writing unit tests and faking/mocking functions which should not/cannot be run during a test case. Some say that such a feature is useful for existing code, but should not be needed for a code which is written testable from the beginning. But, personally I don’t agree that it is always appropriate to inject such dependencies using virtual interfaces or templates. Currently, it is not supposed to become a mocking framework on its own. I hope that I can integrate PowerFake into at least one existing C++ mocking framework. Therefore, currently it doesn’t provide anything beyond faking existing functions.
  • Introducing pylint-django 0.8.0
    Since my previous post was about writing pylint plugins I figured I'd let you know that I've released pylint-django version 0.8.0 over the weekend. This release merges all pull requests which were pending till now so make sure to read the change log.
  • nbdkit filters
    nbdkit is our toolkit for creating Network Block Device (NBD) servers from “unusual” data sources. nbdkit was already configurable by writing simple plugins in several programming languages. Last week Eric Blake and I added a nice new feature: You can now modify existing plugins by placing “filters” in front of them.

Moving to Linux from dated Windows machines

Every day, while working in the marketing department at ONLYOFFICE, I see Linux users discussing our office productivity software on the internet. Our products are popular among Linux users, which made me curious about using Linux as an everyday work tool. My old Windows XP-powered computer was an obstacle to performance, so I started reading about Linux systems (particularly Ubuntu) and decided to try it out as an experiment. Two of my colleagues joined me. Read more

Security: TPM, Yubikey, Holes, Bricking and Uber

  • Trusted Computing
    The Trusted Platform Module on your computer's motherboard could lead to better security for your Linux system. The security of any operating system (OS) layer depends on the security of every layer below it. If the CPU can't be trusted to execute code correctly, there's no way to run secure software on that CPU. If the bootloader has been tampered with, you cannot trust the kernel that the bootloader boots. Secure Boot allows the firmware to validate a bootloader before executing it, but if the firmware itself has been backdoored, you have no way to verify that Secure Boot functioned correctly.
  • Locking the screen when removing a Yubikey

    I have my Yubikey on my key ring, so whenever I leave my computer, I have to remove the Yubikey. So why not lock the screen automatically?

  • Corporate cultural issues hold back secure software development

    The study of over 1,200 IT leaders, conducted by analysts Freeform Dynamics for software company CA Technologies, finds 58 percent of respondents cite existing culture and lack of skills as hurdles to being able to embed security within processes.

  • Uber shrugs off flaw that lets hackers bypass two-factor authentication

    Security researcher Karan Saini found the bug in Uber's two-factor authentication process, which has yet to be rolled out widely to Uber users. The flaw relates to the way an account is authenticated when users log in, meaning hackers [sic] with someone's username and password can drift pass the 2FA with ease.
