  • LLVM 5.0.0 Release

    This release is the result of the community's work over the past six months, including: C++17 support, co-routines, improved optimizations, new compiler warnings, many bug fixes, and more.

  • LLVM 5.0 Released With C++17 Support, Ryzen Scheduler, AMDGPU Vega & Much More

    After delays pushed its release back by about one month, LLVM 5.0 was just released a few minutes ago along with its associated sub-projects like the Clang 5.0 C/C++ compiler.

    LLVM 5.0 features a number of improvements to the ARM and MIPS targets, greater support for the POWER ISA 3.0 in the PowerPC target, the initial AMD Ryzen (znver1) scheduler support (already improved in LLVM 6.0 SVN), support for Intel Goldmont CPUs, greater AVX-512 support, improved Silvermont/Sandybridge/Jaguar schedulers, and initial Radeon Vega (GFX9) support within the AMDGPU target.

  • Android NDK r16: Developers Should Start Using LLVM's libc++ With GCC On The Way Out

    Google has announced the availability today of the Android Native Development Kit (NDK) Release 16. This release is worth mentioning in that Google is now encouraging developers to start using libc++ as their C++ standard library.

    Moving forward, Google will only be supporting LLVM's libc++ as the C++ standard library and not supporting other STLs. The Android platform has already been using libc++ since Lollipop and now they are looking to get more application developers using this STL.

  • Google publishes its documentation style guide for developers

    Documentation is often an afterthought — especially for open-source projects. That can make it harder for newcomers to join a project, for example, and sometimes badly written documentation is worse than having no documentation at all. To help developers write better documentation, Google this week opened up its own developer-documentation style guide.

  • Trying Out FreeBSD/TrueOS On The Xeon Scalable + Tyan GT24E-B7106 Platform

    While we have tested a number of Linux distributions on Intel's new Xeon Scalable platform, here are some initial BSD tests using two Xeon Gold 6138 processors with the Tyan GT24E-B7106 1U barebones server.

  • FreeBSD Developers Tackle AMD Zen/Ryzen Temperature Monitoring Before Linux

    While Linux users of AMD's new Zen-based Ryzen/Threadripper/Epyc processors are still waiting for thermal driver support to hit the mainline Linux kernel, FreeBSD developers have already managed to produce the Zen "Family 17h" CPU thermal monitoring support on their own.

    From this FreeBSD bug report, developers have managed to get the AMD CPU temperature monitoring working for Zen processors under Linux with their existing temperature driver.

  • Trip Report: FreeBSD in China at COPU and LinuxCon

    In May of 2017, we were invited to give a talk about FreeBSD at COPU’s (China Open Source Promotional Unit) Open Source China, Open Source World Summit, which took place June 21-22, in Beijing. This was a tremendous opportunity to talk about the advantages of FreeBSD to the open source leaders and organizations interested in open source. I was honored to represent the Project and Foundation and give the presentation “FreeBSD Advantages and Applications”.

  • A return-oriented programming defense from OpenBSD

    Stack-smashing attacks have a long history; they featured, for example, as a core part of the Morris worm back in 1988. Restrictions on executing code on the stack have, to a great extent, put an end to such simple attacks, but that does not mean that stack-smashing attacks are no longer a threat. Return-oriented programming (ROP) has become a common technique for compromising systems via a stack-smashing vulnerability. There are various schemes out there for defeating ROP attacks, but a mechanism called "RETGUARD" that is being implemented in OpenBSD is notable for its relative simplicity.

  • Trying Out AMD's Ryzen Threadripper On TrueOS, DragonFlyBSD

    Following the AMD Threadripper Linux tests of this week today I finally had a chance to try out some of the BSDs with this 16 core / 32 thread system.

    With the AMD Threadripper 1950X with Gigabyte X399 AORUS Gaming 7 is how I was running these tests. Initial targets were with TrueOS (formerly known as PC-BSD, the desktop-oriented branch of FreeBSD) and DragonFlyBSD.

  • August 2017 Development Projects Update
  • My first patch to OpenBSD

    I followed Preparing a diff and Making your first patch (OpenBSD) to submit my first OpenBSD patch. Guess what? just few hours later, dmesg source file was changed base on my code. Although the final modification is not my code, it is still a great pleasure that I contribute my own effort to help make OpenBSD better!

  • HAMMER2 File-System Continues To Stabilize For DragonFlyBSD

    For those interested in the work being done to the HAMMER2 file-system that's being developed by Matthew Dillon for DragonFlyBSD, it is indeed getting closer to being a working reality.

    We recently heard how the next DragonFlyBSD release will offer it as an experimental option following recent advancements to it. That next DragonFly release should be coming in September.

  • OpenBSD Community Goes Platinum [iophk: "paypal is not an option, I'll have to send some bitcoin their way"]

Lumina desktop – Show me the light

Filed under
Reviews
BSD

The good thing about Qt (as a framework and technology) is that it powers so many interesting products seamlessly, quietly, unassumingly. The bad thing is, sometimes you may use something that has Qt DNA, and yet, you wouldn’t know it unless explicitly told. Such is the case with the Lumina desktop.

This less-known desktop environment powers mostly BSD operating systems, but it does not seem to have caught on in the Linux world that much. At the moment, you are most likely to find it gracing TrueOS, which uses it as its default interface. And yet, with modern architecture under the hood, it could be a suitable alternative to other mainstream desktop environments. Let’s see what gives.

BSD: LLVM, Clang “Absolute FreeBSD”

Filed under
BSD
  • LLVM's Clang C/C++ Compiler Is Still Having Problems With ~5% Of Debian Packages

    Debian developer and LLVM/Clang enthusiast Sylvestre Ledru has provided an update regarding the build results for trying to compile the Debian archive using this GCC compiler alternative.

  • Rebuild of Debian using Clang 3.9, 4.0 and 5.0

    tldr: The percentage of failure is decreasing, Clang support is improving but there is a long way to go.

    The goal of this initiative is to rebuild Debian using Clang as a compiler instead of gcc. I have been doing this analysis for the last 6 years.

    Recently, we rebuilt the archive of the Debian archive with Clang 3.9.1 (July 6th), 4.0.1 (July 6th) and 5.0 rc2 (August 20th).

    For various reasons, we didn't perform a rebuild since June 2016 with version 3.8. Therefor, we took the opportunity to do three over the last month.

  • ARC Backend Merged In LLVM

    LLVM 6.0 SVN/Git now has landed a Synopsys DesignWare ARC processor back-end.

  • AF3e status, 22 August 2017

    Your irregular “Absolute FreeBSD” status report!

    It’s at 123,700 words. 12 of 26 chapters exist as first drafts. (Yes, the last report said 7 of 24. I can’t count.) Two more chapters are partially done. One of those partially-done chapters, on “Pre-Install Considerations,” won’t be done until I finish the whole book. I keep going back to add tidbits to it. It’s complete, except when I find something else I have to add to it.

Debian Developers: Google Summer of Code, Quick Recap of 2017

  • RHL'18 in Saint-Cergue, Switzerland
    In between eating fondue and skiing, I found time to resurrect some of my previous project ideas for Google Summer of Code. Most of them are not specific to Debian, several of them need co-mentors, please contact me if you are interested.
  • Quick recap of 2017
         After the Stretch release, it was time to attend DebConf’17 in Montreal, Canada. I’ve presented the latest news on the Debian Installer front there as well. This included a quick demo of my little framework which lets me run automatic installation tests. Many attendees mentioned openQA as the current state of the art technology for OS installation testing, and Philip Hands started looking into it. Right now, my little thing is still useful as it is, helping me reproduce regressions quickly, and testing bug fixes… so I haven’t been trying to port that to another tool yet. I also gave another presentation in two different contexts: once at a local FLOSS meeting in Nantes, France and once during the mini-DebConf in Toulouse, France. Nothing related to Debian Installer this time, as the topic was how I helped a company upgrade thousands of machines from Debian 6 to Debian 8 (and to Debian 9 since then). It was nice to have Evolix people around, since we shared our respective experience around automation tools like Ansible and Puppet.
