The Clear Containers team at Intel has announced the release of Clear Containers 3.0. "Completely rewritten and refactored, Clear Containers 3.0 uses Go language instead of C and introduces many new components and features. The 3.0 release of Clear Containers brings better integration into the container ecosystem and an ability to leverage code used for namespace based containers."

Facebook relicenses several projects

Friday 22nd of September 2017 10:09:36 PM
Facebook has announced that the React, Jest, Flow, and Immutable.js projects will be moving to the MIT license. This is, of course, a somewhat delayed reaction to the controversy over the "BSD+patent" license previously applied to those projects. "This decision comes after several weeks of disappointment and uncertainty for our community. Although we still believe our BSD + Patents license provides some benefits to users of our projects, we acknowledge that we failed to decisively convince this community."

[$] Linking commits to reviews

Wednesday 20th of September 2017 04:19:01 PM

In a talk in the refereed track of the 2017 Linux Plumbers Conference, Alexandre Courouble presented the email2git tool that links kernel commits to their review discussion on the mailing lists. Email2git is a plugin for cregit, which implements token-level history for a Git repository; we covered a talk on cregit just over one year ago. Email2git combines cregit with Patchwork to link the commit to a patch and its discussion threads from any of the mailing lists that are scanned by patchwork.kernel.org. The result is a way to easily find the discussion that led to a piece of code—or even just a token—changing in the kernel source tree.

GNOME Foundation partners with Purism to support its efforts to build the Librem 5 smartphone

Wednesday 20th of September 2017 03:40:36 PM
Last week KDE announced that they were working with Purism on the Librem 5 smartphone. The GNOME Foundation has also provided its endorsement and support of Purism’s efforts to build the Librem 5. "As part of the collaboration, if the campaign is successful the GNOME Foundation plans to enhance GNOME shell and general performance of the system with Purism to enable features on the Librem 5. Various GNOME technologies are used extensively in embedded devices today, and GNOME developers have experienced some of the challenges that face mobile computing specifically with the Nokia 770, N800 and N900, the One Laptop Per Child project’s XO laptop and FIC’s Neo1973 mobile phone."

An intro to machine learning (Opensource.com)

Wednesday 20th of September 2017 03:17:55 PM
Ulrich Drepper, once again an engineer at Red Hat, writes about machine learning on opensource.com. "Machine learning and artificial intelligence (ML/AI) mean different things to different people, but the newest approaches have one thing in common: They are based on the idea that a program's output should be created mostly automatically from a high-dimensional and possibly huge dataset, with minimal or no intervention or guidance from a human. Open source tools are used in a variety of machine learning and artificial intelligence projects. In this article, I'll provide an overview of the state of machine learning today."

[$] Building the kernel with clang

Tuesday 19th of September 2017 05:18:10 PM

Over the years, there has been a persistent effort to build the Linux kernel using the Clang C compiler that is part of the LLVM project. We last looked in on the effort in a report from the LLVM microconference at the 2015 Linux Plumbers Conference (LPC), but we have followed it before that as well. At this year's LPC, two Google kernel engineers, Greg Hackmann and Nick Desaulniers, came to the Android microconference to update the status; at this point, it is possible to build two long-term support kernels (4.4 and 4.9) with Clang.

Moore: The 2017 Linux Security Summit

Tuesday 19th of September 2017 02:46:44 PM
Paul Moore has posted his notes from the 2017 Linux Security Summit, held September 14 and 15 in Los Angeles. "LinuxKit was designed to make it easy for people to create their own Linux distribution, with a strong focus on minimal OS installs such as one would use in a container hosting environment. LinuxKit has several features that make it interesting from a security perspective, the most notable being the read-only rootfs which is managed using external tooling. Applications are installed via signed container images."

Schaller: Launching Pipewire

Tuesday 19th of September 2017 01:47:27 PM
Christian Schaller announces Pipewire, a media system that is meant to eventually replace PulseAudio and handle video as well. "Anyway as work progressed Wim decided to also take a look at Jack, as supporting the pro-audio usecase was an area PulseAudio had never tried to do, yet we felt that if we could ensure Pipewire supported the pro-audio usecase in addition to consumer level audio and video it would improve our multimedia infrastructure significantly and ensure pro-audio became a first class citizen on the Linux desktop." A video-only version will be shipping in Fedora 27.

[$] Testing kernels

Tuesday 19th of September 2017 01:40:04 AM

New kernels are released regularly, but it is not entirely clear how much in-depth testing they are actually getting. Even the mainline kernel may not be getting enough of the right kind of testing. That was the topic for a "birds of a feather" (BoF) meeting at this year's Linux Plumbers Conference (LPC) held in mid-September in Los Angeles, CA. Dhaval Giani and Sasha Levin organized the BoF as a prelude to the Testing and Fuzzing microconference they were leading the next day.

[$] Notes from the LPC scheduler microconference

Monday 18th of September 2017 11:11:04 PM
The scheduler workloads microconference at the 2017 Linux Plumbers Conference covered several aspects of the kernel's CPU scheduler. While workloads were on the agenda, so were a rework of the realtime scheduler's push/pull mechanism, a distinctly different approach to multi-core scheduling, and the use of tracing for workload simulation and analysis. As the following summary shows, CPU scheduling has not yet reached a point where all of the important questions have been answered.

XFree KWin, Plasma, KDE, and Qt/GTK

  • Announcing the XFree KWin project
    Over the last weeks I concentrated my work on KWin on what I call the XFree KWin project. The idea is to be able to start KWin/Wayland without XWayland support. While most of the changes required for it are already in Plasma 5.11, not everything got ready in time, but now everything is under review on phabricator, so it’s a good point in time to talk about this project.
  • Adapta Theme is Now Available for the #KDE Plasma Desktop
    A new port brings the Adapta GTK theme to the KDE Plasma 5 desktop for the first time, news that will please fans of its famous flat stylings.
  • A New Project To Let You Run Qt Apps With GTK+ Windowing System Integration
    A Norwegian developer has developed a new Qt platform abstraction plug-in to let Qt applications make use of GTK+ for windowing system integration. The Qt apps rely upon GTK+ as a host toolkit to provide GTK menus, GTK for input, and other integration bits.
  • Ant is a Flat GTK Theme with a Bloody Bite
    Between Arc, Adapta and Numix it kind of feels like Linux has the whole flat GTK theme thing covered. But proving their’s always room for one more is Ant.

Development: Blockchain for Good Hackathon, ASUS Tinker Board, React License, JavaScript, Pascal, Python

  • Blockchain for Good Hackathon, Saturday, 30 September and Sunday, 1 October
    The Blockchain for Good Hackathon takes place Saturday, 30 September and Sunday, 1 October. Full agenda can be found here.
  • ASUS Tinker Board Is An Interesting ARM SBC For About $60 USD
    Earlier this year ASUS announced the Tinker Board as their first step into the ARM single board computer world. Earlier this month I finally received a Tinker Board for testing and it has been quite interesting to say the least. The Tinker Board with its Rockchip SoC has been among the most competitive ARM SBCs we have tested to date in its price range and the form factor is compatible with the Raspberry Pi.

  • Facebook to Relicense React Under MIT [Ed: as we hoped [1, 2]]
    Facebook has decided to change the React license from BSD+Patents to MIT to make it possible for companies to include React in Apache projects, and to avoid uncertain relationship with the open source community. Adam Wolff, an Engineering Director at Facebook, has announced that a number of projects - React, Jest, Flow, and Immutable.js – will soon start using the more standard MIT License instead of BSD+Patents. The reason provided is "because React is the foundation of a broad ecosystem of open source software for the web, and we don't want to hold back forward progress for nontechnical reasons." While aware that the React’s BSD+Patents license has created "uncertainty" among users of the library, prompting some to select an alternative solution, Facebook does not "expect to win these teams back" but they still hope some will reconsider the issue. The change in license will become effective when React 16 will be released next week. Regarding other projects, Wolff said that "many of our popular projects will keep the BSD + Patents license for now", while they are "evaluating those projects' licenses too, but each project is different and alternative licensing options will depend on a variety of factors." It seems from this clause that Facebook plans to get rid of the BSD+Patents license entirely, but they need to figure out the best option for each project. [...] Facebook’s plan to switch to a standard license MIT, supported by Apache, completely solves this problem with React and several other projects. It remains to see what happens with the license of other Facebook projects, and how much this license issue has affected how React is perceived by the community.
