  • 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.

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.

“Respects Your Freedom” (RYF) and Purism's Librem 5

  • Purism's Librem 5 To Rely On Secondary Processor For Binary Blobs
    With not being able to deliver a 100% fully free software / libre system, the Librem 5 smartphone will rely upon a secondary processor for dealing with the necessary binary blobs for hardware initialization to keep them out of touch from the U-Boot boot-loader and Linux kernel. The first road-block in their effort to make the Librem 5 smartphone as open as possible is the DDR PHY with firmware blobs needed for the DDR4 memory training process at boot time. With it not being realistic for them to rewrite the firmware blob to do the DDR4 PHY training, they are planning to punt the binary-only blobs out to a secondary processor. In doing so, they can also apply for an exclusion with the Free Software Foundation for still having a device that "Respects Your Freedom" while still having necessary binary blobs at play.
  • Solving the first FSF RYF hurdle for the Librem 5
    While investigating using the i.MX 8 for the Librem 5 phone we found an issue that would have been problematic for us to obtain the Free Software Foundation’s “Respects Your Freedom” (RYF) hardware endorsement...

Red Hat: Education, Automation, RHEL 6.10 and More

  • Red Hat, Lord Wandsworth College and University of Surrey collaborate
    Red Hat, the world’s leading provider of open source solutions, has announced its collaboration with Lord Wandsworth College (LWC), an independent school for girls and boys aged 11 to 18, and the University of Surrey, a public research university specialising in science, engineering, medicine and business, on the Open Schools Coding Competition, designed to inspire the next generation of coders and software developers. In so doing, the competition hopes to contribute to building the UK’s digital talent pool. The competition is now in its second year, with 10 schools and approximately 100 students in the UK taking part. The competition aims to engage children ahead of making their subject choices for GCSE, so is open to Key Stage 3 students. It challenges teams of students to use any free visual programming environment to create a gaming app that will help a charity of their choice. The competition enables participants to apply the basic principles of open source software development and open collaboration to solve a real world problem in a fun and competitive environment, with the opportunity to win a prize for their team and recognition for their school. In choosing a charitable cause, each student can gain a sense of how they can use digital skills to make their own contribution to addressing societal challenges and how open source technology and methodology can drive positive change in the world.

Security: Updates, Reproducible Builds and Windows 'Fun'

  • Security updates for Tuesday
  • Reproducible Builds: Weekly report #164
  • PyRoMineIoT cryptojacker uses NSA exploit to spread
    Larry Trowell, principal consultant with Synopsys Software Integrity Group, said the government shares some of the blame for the NSA exploit. "It's in every country's interest to develop systems enabling offensive and defensive strategies to protect individuals and national services," Trowell wrote via email. "There is no fault in that. If the NSA does have some blame to share in this situation, it is for allowing secrets to be exfiltrated -- not in developing them." Jett said although the NSA exploit was stolen, "they didn't create the vulnerabilities that allow for the malware to exploit devices." "As such, you can't hold them responsible for the malware that has emerged from the EternalRomance exploit. Vendors whose products are vulnerable to EternalRomance are responsible for resolving the exploit problem," Jett wrote. "Additionally, it has been more than a year since the NSA exploits were released, and vendors have created patches. It becomes incumbent on the users to make sure they are properly patching their software and reducing the threat surface for these exploits."

  • 6-Year-Old Malware Injects Ads, Takes Screenshots On Windows 10
    A sneaky and persistent malware has surfaced which spams Windows 10 PCs with ads and takes screenshots to eventually send it to the attackers. Security researchers at Bitdefender found this malware named Zacinlo which first appeared in 2012. About 90% of Zacinlo’s victims are from the US running Microsoft Windows 10. There are other victims too from Western Europe, China, and India with a small fraction running Windows 7 or 8.
