  • The Prominent Changes Of Phoronix Test Suite 8.0

    With development on Phoronix Test Suite 8.0 wrapping up for release in the coming weeks, here is a recap of some of the prominent changes for this huge update to our open-source, cross-platform benchmarking software.

  • AMD AOCC 1.2 Code Compiler Offers Some Performance Benefits For EPYC

    Last month AMD released the AOCC 1.2 compiler for Zen systems. This updated version of their branched LLVM/Clang compiler with extra patches/optimizations for Zen CPUs was re-based to the LLVM/Clang 6.0 code-base while also adding in experimental FLANG support for Fortran compilation and various other unlisted changes to their "znver1" patch-set. Here's a look at how the performance compares with AOCC 1.2 to LLVM Clang 6.0 and GCC 7/8 C/C++ compilers.

  • More Roads And Faster Browsers

    And it's exactly what is happening with our Web pages. Browsers become more performant. So developers instead of using this extra performance to make the page extra-blazingly fast, we use it to pack more DOM nodes, CSS animations and JavaScript driven user experiences.

  • Firefox 61 Beta 6 Testday Results

    As you may already know, last Friday – May 18th – we held a new Testday event, for Firefox 61 Beta 6.

    Thank you all for helping us make Mozilla a better place: gaby2300, Michal, micde, Jarrod Michell, Petri Pollanen, Thomas Brooks.

    Yes, folks. This year SIGGRAPH 2018 is in Canada and we’ll be there at the Qt booth, showing off our latest tooling and demos. These days, you’d be surprised where Qt is used under the hood, even by the biggest players in the 3D world!

  • 9 Best Free Python Integrated Development Environments

    Python is a widely used general-purpose, high level programming language. It’s easy to read and learn. It’s frequently used for science, data analysis, and engineering. With a burgeoning scientific community and ecosystem, Python is an excellent environment for students, scientists and organizations that develop technology software.

    One of the essential tools for a budding Python developer is a good Integrated Development Environment (IDE). An IDE is a software application that provides comprehensive facilities to programmers for software development.

    Many coders learn to code using a text editor. And many professional Python developers prefer to stay with their favourite text editor, in part because a lot of text editors can be used as a development environment by making use of plugins. But many Python developers migrate to an IDE as this type of software application offers, above all else, practicality. They make coding easier, can offer significant time savings with features like autocompletion, and built-in refactoring code, and also reduces context switching. For example, IDEs have semantic knowledge of the programming language which highlights coding problems while typing. Compiling is ‘on the fly’ and debugging is integrated.

  • Want to Debug Latency?

    In the recent decade, our systems got complex. Our average production environments consist of many different services (many microservices, storage systems and more) with different deployment and production-maintenance cycles. In most cases, each service is built and maintained by a different team — sometimes by a different company. Teams don’t have much insight into others’ services. The final glue that puts everything together is often a staging environment or sometimes the production itself!

    Measuring latency and being able to react to latency issues are getting equally complex as our systems got more complex. This article will help you how to navigate yourself at a latency problem and what you need to put in place to effectively do so.

  • The open source AsteroidOS is a new alternative to Wear OS

    AsteroidOS is a new Linux-based open source operating system that can be used as a replacement to Wear OS.

    A small team of developers have been hard at work on the smartwatch platform for the last four years. As the culmination of their efforts, this week the first stable version was made available to the public. It plays nice with a few Wear OS-compatible smartwatches.

  • Das blinkenlights are back thanks to RPi revival of the PDP-11

    The designers left the I2C port of the Raspberry Pi free for hacks, and “it is not very hard to add support for such things in the simh emulator, so the PiDP-11 can use them as I/O”.

    The SR switches on the PiDP-11's SR switches can be set to boot various operating systems (this part is a work in progress), so instead of RSX-11MPlus users can choose BSD, DOS-11, Unix System 6 or System 7 and the like.

  • Extreme downhill free-riding game 'Descenders' just had a huge update, needs a quick fix on Linux

    Descenders is an extreme downhill free-riding game currently in Early Access and their first major update just went live. I've been quite a big fan of it, as it showed a massive amount of promise at the initial release.

    I held off on covering this update right away, since the released version of the update broke the 64bit Linux version. Nearly a week later and no fix, so here's how you can fix it manually:

    Right click on it in your Steam library and go to properties, then hit the Local Files tab up the top and press Browse Local Files… once there, open the Descenders_Data folder, go into the Plugins folder and delete "libfmod.so".

  • WolfenDoom - Blade of Agony is looking for AMD testers

  • Open-world roguelike RPG 'Stoneshard' will have Linux support, nearly hit the Kickstarter goal

    Stoneshard [Official Site] is a pretty good sounding open-world RPG, it's currently on Kickstarter with a promise of Linux support and they've nearly hit their goal. With 26 days left to go, they've hit $28K of their $30K goal, so it looks like they will manage it easily.

    Inspired by the likes of Diablo, ADOM, Darkest Dungeon and more, they have a lot to live up to in terms of their inspiration. What makes it sound quite interesting, is the survival elements you heal to deal with like diseases, broken bones, mental health and more.

  • Mesa 18.1 Officially Released as the Most Advanced Linux Graphics Stack Series

    The development team behind the open-source Mesa graphics stack announced over the weekend the general availability of the final Mesa 18.1 release for Linux-based operating systems.

    The Mesa 18.1 series comes approximately two months after the 18.0 branch, which probably most GNU/Linux distributions are using these days, and which already received its fourth maintenance updates. Mesa 18.1 introduces a few new features across all supported graphics drivers, but it's mostly another stability update.

  • Mach64 & Rendition Drivers Now Work With X.Org Server 1.20

    Anyone happening to have an ATI Mach 64 graphics card from the mid-90's or a 3Dfx-competitor Rendition graphics card also from the 90's can now enjoy the benefits of the recently released X.Org Server 1.20.

    Mach 64 and Rendition are among the X.Org DDX (2D) drivers still being maintained for the X.Org Server. Even though using either of these two decade old graphics cards would be painfully slow with a Linux desktop stack from today especially if paired with CPU and memory from that time-frame, the upstream X.Org developers still appear willing to maintain support for these vintage graphics processors. Well, at least as far as ensuring the drivers still build against the newest software -- we've seen before out of these old drivers that they are updated to work for new releases, but at times can actually be broken display support for years before anyone notices with said hardware.

Tesla Compliance

  • It Only Took Six Years, But Tesla Is No Longer Screwing Up Basic Software Licenses

    Tesla is actually doing it. The electric car maker is starting to abide by open source software licenses that it had previously ignored, and releasing the code it’s sat on for over six years, according to Electrek.

    Tesla’s super smart cars, specifically the sporty Model S sedan and Model X SUV, incorporate a lot of open source software, from Linux, the open source operating system, to BusyBox, a collection of tools that are useful when working with Linux and other UNIX environments (like macOS). All open source software is released under licenses and one of the most popular licenses is the GPL, or General Public License.

  • Tesla releases some of its software to comply with open source rules

    Tesla makes some of the most popular electric vehicles out there and the systems in those cars rely on open source software for operating systems and features. Some of that open source software that is used in Tesla products has a license agreement that requires Tesla to at least offer the user access to the source code. Tesla hasn’t been making that offer.

  • Tesla open sources some of its Autopilot source code

    ELECTRIC CAR MAKER Tesla tends to keep the details of its work under lock and key, but now Elon Musk's company is plonking some of its automotive tech source code into the open source community.

    Tesla dumped some of its code used to build the foundations of its Autopilot semi-autonomous driving tech and the infotainment system found on the Model S and Model X cars, which makes uses of Nvidia's Tegra chipset, on GitHub.

    Even if you're code-savvy, don't go expecting to build your own autonomous driving platform on top of this source code, as Tesla has still kept the complete Autopilot framework under wraps, as well as deeper details of the infotainment system found in its cars. But it could give code wranglers a better look into how Tesla approaches building infotainment systems and giving its cars a dose of self-driving smarts.

  • Tesla releases source code

    Tesla has taken its first step towards compliance with the GNU General Public Licence (GPL) by releasing some of its source code.

    The car maker has opened two GitHub repositories which contain the buildroot material used to build the system image on its Autopilot platform, and the kernel sources for the boards and the Nvidia-based infotainment system in the Model S and Model X.

  • An introduction to cryptography and public key infrastructure

    Secure communication is quickly becoming the norm for today's web. In July 2018, Google Chrome plans to start showing "not secure" notifications for all sites transmitted over HTTP (instead of HTTPS). Mozilla has a similar plan. While cryptography is becoming more commonplace, it has not become easier to understand. Let's Encrypt designed and built a wonderful solution to provide and periodically renew free security certificates, but if you don't understand the underlying concepts and pitfalls, you're just another member of a large group of cargo cult programmers.

Security: VPNFilter, Encryption in GNU/Linux, Intel CPU Bug Affecting rr Watchpoints

  • [Crackers] infect 500,000 consumer routers all over the world with malware

    VPNFilter—as the modular, multi-stage malware has been dubbed—works on consumer-grade routers made by Linksys, MikroTik, Netgear, TP-Link, and on network-attached storage devices from QNAP, Cisco researchers said in an advisory. It’s one of the few pieces of Internet-of-things malware that can survive a reboot. Infections in at least 54 countries have been slowly building since at least 2016, and Cisco researchers have been monitoring them for several months. The attacks drastically ramped up during the past three weeks, including two major assaults on devices located in Ukraine. The spike, combined with the advanced capabilities of the malware, prompted Cisco to release Wednesday’s report before the research is completed.

  • Intel CPU Bug Affecting rr Watchpoints
    I investigated an rr bug report and discovered an annoying Intel CPU bug that affects rr replay using data watchpoints. It doesn't seem to be hit very often in practice, which is good because I don't know any way to work around it. It turns out that the bug is probably covered by an existing Intel erratum for Skylake and Kaby Lake (and probably later generations, but I'm not sure), which I even blogged about previously! However, the erratum does not mention watchpoints and the bug I've found definitely depends on data watchpoints being set. I was able to write a stand-alone testcase to characterize the bug. The issue seems to be that if a rep stos (and probably rep movs) instruction writes between 1 and 64 bytes (inclusive), and you have a read or write watchpoint in the range [64, 128) bytes from the start of the writes (i.e., not triggered by the instruction), then one spurious retired conditional branch is (usually) counted. The alignment of the writes does not matter, and it's not related to speculative execution.

In Memoriam: Robin "Roblimo" Miller, a Videographer and Free Software Champion

Videographer Robin Roblimo Miller

Robin "Roblimo" Miller was a clever, friendly, and very amicable individual who everyone I know has plenty of positive things to say about. I had the pleasure of speaking to him for several hours about anything from personal life and professional views. Miller was a very knowledgeable person whose trade as a journalist and video producer I often envied. I have seen him facing his critics in his capacity as a journalist over a decade ago when he arranged a debate about OOXML (on live radio). Miller, to me, will always be remembered as a strong-minded and investigative journalist who "did the right thing" as the cliché goes, irrespective of financial gain -- something which can sometimes be detrimental to one's longterm health. Miller sacrificed many of his later years to a cause worth fighting for. This is what we ought to remember him for. Miller was - and always will be - a FOSS hero.

May everything you fought for be fulfilled, Mr. Miller. I already miss you.
