October project goals update (Rust Blog)

Par : jzb
31 octobre 2024 à 21:26

The Rust blog has an update on its progress on some of its project goals. One of the project's flagship goals is to resolve the biggest blockers to Linux building on stable Rust:

Finally, we have been finding an increasing number of stabilization requests at the compiler level, and so @wesleywiser and @davidtwco from the compiler team have started attending meetings to create a faster response. One of the results of that collaboration is RFC #3716, authored by Alice Ryhl, which proposes a method to manage compiler flags that modify the target ABI. Our previous approach has been to create distinct targets for each combination of flags, but the number of flags needed by the kernel make that impractical. Authoring the RFC revealed more such flags than previously recognized, including those that modify LLVM behavior.

[$] The Overture open-mapping project

OpenStreetMap tends to dominate the space for open mapping data, but it is not the only project working in this area. At the 2024 Open Source Summit Japan, Marc Prioleau presented the Overture Maps Foundation, which is building and distributing a set of worldwide maps under open licenses. Overture may have a similar goal to OpenStreetMap, but its approach and intended uses are significantly different.

A new release of Raspberry Pi OS

Par : jzb
30 octobre 2024 à 16:41

The Raspberry Pi project has announced a new version of Raspberry Pi OS. It includes a number of significant changes, the most notable of which is that the Raspberry Pi Desktop now uses Wayland by default for all Pi models using the labwc compositor:

For most of this year, we have been working on porting labwc to the Raspberry Pi Desktop. This has very much been a collaborative process with the developers of both labwc and wlroots: both have helped us immensely with their support as we contribute features and optimisations needed for our desktop.

This release also features Linux 6.6.51, improved touchscreen support, a new screen configuration tool called raindrop, and more. See the release notes for a full list of changes.

[$] An update on Apple M1/M2 GPU drivers

The kernel graphics driver for the Apple M1 and M2 GPUs is, rather famously, written in Rust, but it has achieved conformance with various graphics standards, which is also noteworthy. At the X.Org Developers Conference (XDC) 2024, Alyssa Rosenzweig gave an update on the status of the driver, along with some news about the kinds of games it can support (YouTube video, slides). There has been lots of progress since her talk at XDC last year (YouTube video), with, of course, still more to come.

Thunderbird for Android now available

The first stable release of the Thunderbird mail client for Android is now available:

Just over two years ago, we announced our plans to bring Thunderbird to Android by taking K-9 Mail under our wing. The journey took a little longer than we had originally anticipated and there was a lot to learn along the way, but the wait is finally over! For all of you who have ever asked "when is Thunderbird for Android coming out?", the answer is – today!

It is immediately available on the Google Play Store, via GitHub Releases, or from the Thunderbird web site, and it will be "coming soon" to the F-Droid repository for FOSS Android applications. See the release notes for detailed information about Thunderbird 8.0 for Android.

[$] A new approach to validating test suites

Par : daroc
29 octobre 2024 à 17:01

The first program that Martin Pool ever wrote, he said, had bugs; the ones he's writing now most likely have bugs too. The talk Pool gave at RustConf this year was about a way to try to write programs with fewer bugs. He has developed a tool called cargo-mutants that highlights gaps in test coverage by identifying functions that can be broken without causing any tests to fail. This can be a valuable complement to other testing techniques, he explained.

Flock: a Flutter fork

Par : corbet

A project called Flock has announced its existence. Flock is a fork of the Flutter user-interface toolkit project, motivated by frustration with the resources that Google is putting into Flutter.

We describe Flock as "Flutter+". In other words, we do not want, or intend, to fork the Flutter community. Flock will remain constantly up to date with Flutter. Flock will add important bug fixes, and popular community features, which the Flutter team either can't, or won't implement.

(LWN looked at Flutter in 2020).

Coker: The CUPS vulnerability

Debian Developer Russell Coker has written up an analysis of the remote exploit of CUPS announced in September:

He seems to have a different experience to me of reporting bugs, I have had plenty of success getting bugs fixed without hyping them. I just report the bug, wait a while, and it gets fixed. [...] I was quite confident that my systems wouldn't be at any risk.

When it was published my opinion was proven to be correct, it turned out to be a series of CUPS bugs.

Open Source Initiative announces Open Source AI Definition 1.0

The Open Source Initiative (OSI) has announced the release of version 1.0 of the Open Source AI Definition:

The OSAID offers a standard by which community-led, open and public evaluations will be conducted to validate whether or not an AI system can be deemed Open Source AI. This first stable version of the OSAID is the result of multiple years of research and collaboration, an international roadshow of workshops, and a year-long co-design process led by the Open Source Initiative (OSI).

LWN covered the OSAID process, and final release candidate, on October 25.

[$] The performance of the Rust compiler

Sparrow Li presented virtually at RustConf 2024 about the current state of and future plans for the Rust compiler's performance. The compiler is relatively slow to compile large programs, although it has been getting better over time. The next big performance improvement to come will be parallelizing the compiler's parsing, type-checking, and related operations, but even after that, the project has several avenues left to explore.

[$] AutoFDO and Propeller

Par : jake
28 octobre 2024 à 15:15
Rong Xu and Han Shen described the kernel-optimization techniques that Google uses in the toolchains track at the 2024 Linux Plumbers Conference. They talked about automatic feedback-directed optimization (AutoFDO), which can be used with the Propeller optimizer to produce kernels with better performance using profile information gathered from real workloads. There is a fair amount of overlap between these tools and the BOLT post-link optimizer, which was the subject of a talk that directly preceded this session.

Kernel prepatch 6.12-rc5

Linus has released 6.12-rc5 for testing.

rc5 looks perfectly normal, and maybe even on the small side of normal. The diffstat looks nice and flat too, with the exception of the removal of the da8xx fbdev driver due to it having been replaced by the tilcdc driver. And I'm sure we're all thinking the same thing: "What lovely descriptive driver names we have".

[$] OSI readies controversial Open AI definition

Par : jzb
25 octobre 2024 à 21:02

The Open Source Initiative (OSI) has been working on defining Open Source AI—that is what constitutes an AI system that can be used, studied, modified, and shared for any purpose—for almost two years. Its board will be voting on the Open Source AI Definition (OSAID) on Sunday, October 27, with the 1.0 version slated to be published on October 28. It is never possible to please everyone in such an endeavor, and it would be folly to make that a goal. However, a number of prominent figures in the open-source community have voiced concerns that OSI is setting the bar too low with the OSAID—which will undo decades of community work to cajole vendors into adhering to or respecting the original Open Source Definition (OSD).
