  • Power Management Updates Land In The Linux 4.19 Kernel

    Intel's Rafael Wysocki has submitted the ACPI and power management updates today for the Linux 4.19 kernel which were subsequently merged by Linus Torvalds.

  • Linux 4.19 Git Contains a lot of Performance Impacting Spectre Mitigation Updates

    Another round of commits regarding anti-Spectre security have landed up in the Linux 4.19 kernel git tree, which may have possible performance impacts for the kernel.

    While Spectre is still only a somewhat theoretical threat, as its entirely too slow to be used in a serious attack, many folks are taking its future potential quite seriously and arming up against it.

  • Linux 4.19 Kernel to Receive a Ton of Audio Hardware Updates for Improved Linux Sound Capabilities

    Linux audiophiles may have something to rejoice about, as a recent pull request from SUSE’s Takashi Iwai focuses on a plethora of sound subsystem updates for the Linux 4.19 kernel, including a lot of latest hardware support and overall improvements for Linux’s audio capabilities.

  • Updated Vega 20 Open-Source Driver Patches Posted, Including PSP & PowerPlay Support

    Back in May AMD posted initial open-source "Vega 20" patches and support for that yet-to-launch graphics processor was subsequently merged for the Linux 4.18 kernel. More of the Vega 20 AMDGPU kernel driver enablement has now been posted.

    This latest 69,910 lines of code -- before fretting, most of that is auto-generated header files for the GPU -- notably adds PSP (Platform Security Processor) and SMU (System Management Unit) for Vega 20. With the SMU enablement code, it's also now wired in to enable Vega 20 PowerPlay support as well as related power/clocking-functionality like OverDrive overclocking is also available.

5 of the Best Linux Educational Software and Games for Kids

Linux is a very powerful operating system, and that explains why it powers most of the servers on the Internet. Though it may not be the best OS in terms of user friendliness, its diversity is commendable. Everyone has their own need for Linux. Be it for coding, educational purposes or the internet of things (IoT), you’ll always find a suitable Linux distro for every use. To that end, many have dubbed Linux as the OS for future computing.

Because the future belongs to the kids of today, introducing them to Linux is the best way to prepare them for what the future holds. This OS may not have a reputation for popular games such as FIFA or PES; however, it offers the best educational software and games for kids. These are five of the best Linux educational software to keep your kids ahead of the game.

  • Linux 4.18 brings support for Vega M, Volta GV100 and, er, SPECK

    AFTER A WEEK'S DELAY, Linux kernel 4.18 stable has arrived.

    Announcing the release on Sunday, head of Linuxing Linus Torvalds said: "One week late(r) and here we are - 4.18 is out there. It was a very calm week, and arguably I could just have released on schedule last week, but we did have some minor updates."

    One notable change is that there's been a lot of code ditched - around 100,000 lines of obsolete code has been slashed.

  • The AMD Threadripper 2990WX shows even higher numbers when benchmarked on Linux

    Phoronix has done a performance comparison of the AMD Threadripper 2990WX in Windows 10 Pro and Linux and the results show Threadripper numbers significantly lower under Windows 10 Pro than in Linux. In some tests such as 7-Zip Compression, the Threadripper 2990WX posted almost 58% higher scores in Linux compared to Windows 10 Pro implying that Linux is a better OS of choice when testing high core count CPUs.

  • Diversity Empowerment Summit Highlights Importance of Allies

    Diversity and inclusion are hot topics as projects compete to attract more talent to power development efforts now as well as build their ranks to carry the projects into the future. The Diversity Empowerment Summit co-located with Open Source Summit coming up in Vancouver August 29-31, will offer key insights to help your project succeed in these endeavors.

    Although adoption of diversity and inclusion policies is generally seen as simply the right thing to do, finding good paths to building and implementing such policies within existing community cultures continues to be challenging. The Diversity Empowerment Summit, however, provides hard insights, new ideas, and proven examples to help open source professionals navigate this journey.

  • Hollywood rolls out red carpet for open source developers

    The launch of the ASWF is almost like creating a GitHub for the developers behind motion pictures, but open source is nothing new to the film industry. It dates back about 20 years, Andy Maltz, managing director of the Science and Technology Council at the Academy, told CIO Dive.

    Film "is the only art form that has a fundamental reliance on technology," he said. The film industry's use of tech dates back to photochemical technologies and proceeds to today's digital image capture.

Debian GNU/Linux project to mark 25th birthday on Thursday

Filed under
Debian

The Debian GNU/Linux project will turn 25 on Thursday, with the Linux distribution having made its debut on 16 August in 1993 under the leadership of the late Ian Murdock.

In its original manifesto, Murdock stated: "Many distributions have started out as fairly good systems, but as time passes attention to maintaining the distribution becomes a secondary concern."

Maintaining a Debian system was made simple after some developers created a package management system known as apt.

Apt — and its derivatives like aptitude and synaptic — have served to make the task of updating a Debian system simple. With apt, the secondary concern that Murdock referred to was effectively taken care of. Incidentally, there are now about 29,000 packages available in Debian.

Graphics/Benchmarks
  • [ANNOUNCE] libinput 1.11.902

    The second RC for libinput 1.12 is now available.

    First a heads-up, this is probably going to be a longer RC cycle than usual,
    just look at the commit count for rc1..rc2 below. I don't have any
    additional large features planned for 1.12, so the rest should just be
    bugfixing and polishing now.

  • Libinput 1.12 RC2 Continues Working On Improving Linux Touchpad Behavior

    We've known libinput 1.12 is going to be a significant release and that's still holding true in looking at the second release candidate for this Wayland/X.Org input handling library.

    Libinput 1.12 RC1 was working on replacing its udev "hwdb" hardware database with its own quirk handling system, migrating documentation from Sphinx to ReadTheDocs, FreeBSD support, improved trackpoint code, various touchpad fixes and improvements, and other input handling tweaks.

  • xf86-video-v4l X.Org Driver Sees First New Release In A Decade

    The xf86-video-v4l v0.3.0 driver was announced today as the first new release for this DDX driver in ten years.

  • Intel Publishes New DRM Driver For Their Arria 10 FPGA System

    An Intel engineer has published the "Intel FPGA Video and Image Processing Suite" DRM driver today for Linux. This Direct Rendering Manager is intended for use with their Arria 10 FPGA system when combined with Intel DisplayPort IP.

  • RADV Now Supports On-Demand Compilation Of Built-In Shaders

    For helping out the RADV Vulkan driver in cases where no shader cache is available, this open-source Mesa Radeon Vulkan driver now supports the on-demand compilation of built-in shaders.

    On cases like Android, ChromeOS, or sandboxes where no on-disk shader cache is available due to write/security permissions, RADV can take a while to start-up for some programs due to having to compile all of the built-in pipelines at start. RADV co-founder Bas Nieuwenhuizen says this process can take one to four seconds for the creation of a device.

Moz/FF
  • Rustfmt 1.0 release candidate

    The current version of Rustfmt, 0.99.2, is the first 1.0 release candidate. It is available on nightly and beta (technically 0.99.1 there) channels, and from the 13th September will be available with stable Rust.

    1.0 will be a huge milestone for Rustfmt. As part of it's stability guarantees, it's formatting will be frozen (at least until 2.0). That means any sub-optimal formatting still around will be around for a while. So please help test Rustfmt and report any bugs or sub-optimal formatting.

  • Welcome Amy Keating, our incoming General Counsel

    Amy joins Mozilla from Twitter, Inc. where she has been Vice President, Legal and Deputy General Counsel. When she joined Twitter in 2012, she was the first lawyer focused on litigation, building out the functions and supporting the company as both the platform and the employee base grew in the U.S. and internationally. Her role expanded over time to include oversight of Twitter’s product counseling, regulatory, privacy, employment legal, global litigation, and law enforcement legal response functions.

  • Building Extension APIs with Friend of Add-ons Oriol Brufau

    Please meet Oriol Brufau, our newest Friend of Add-ons! Oriol is one of 23 volunteer community members who have landed code for the WebExtensions API in Firefox since the technology was first introduced in 2015. You may be familiar with his numerous contributions if you have set a specific badge text color for your browserAction, highlighted multiple tabs with the tabs.query API, or have seen your extension’s icon display correctly in about:addons.

    While our small engineering team doesn’t always have the resources to implement every approved request for new or enhanced WebExtensions APIs, the involvement of community members like Oriol adds considerable depth and breadth to technology that affects millions of users. However, the Firefox code base is large, complex, and full of dependencies. Contributing code to the browser can be difficult even for experienced developers.

    As part of celebrating Oriol’s achievements, we asked him to share his experience contributing to the WebExtensions API with the hope that it will be helpful for other developers interested in landing more APIs in Firefox.
