Kernel prepatch 6.7-rc8

Ned, 12/31/2023 - 22:44
Linus has released 6.7-rc8 for testing.

So as expected, pretty much nothing happened over the holiday week. We've got literally just 45 files changed, and almost a third of those files aren't even kernel code (ie things like selftests, scripting, Kconfig and maintainer file updates). And some of the rest is prep-work and cleanups for future (real) changes.

But we do have a couple of real fixes in there, and I suspect we'll get a few more next week as people come back from their food-induced torpor.

Julia 1.10 released

Ned, 12/31/2023 - 22:05
The Julia programming language project has released Julia v1.10. It is mainly a performance release, with only two new language features mentioned in the release notes: "JuliaSyntax.jl is now used as the default parser, providing better diagnostics and faster parsing." and the addition of two Unicode symbols for use as binary operators: "⥺ (U+297A, \leftarrowsubset) and ⥷ (U+2977, \leftarrowless)". Package-loading time has been improved further and the mark phase of garbage collection has been parallelized, among other improvements.

Gnuplot 6.0 released

Ned, 12/31/2023 - 20:47
Version 6.0 of the Gnuplot plotting system has been released.

Gnuplot has been supported and under active development since 1986. This is the first new major version of gnuplot since the release of version 5 in January 2015. It introduces extensions to the gnuplot command language, an expanded collection of special and complex-valued functions, additional 2D and 3D plotting styles, and support for new output protocols.

See the release notes for details.

Gentoo in binary form

Pet, 12/29/2023 - 16:17
Gentoo Linux is the prototypical source-based distribution, but there is now a binary installation option available as well.

To speed up working with slow hardware and for overall convenience, we’re now also offering binary packages for download and direct installation! For most architectures, this is limited to the core system and weekly updates - not so for amd64 and arm64 however. There we’ve got a stunning >20 GByte of packages on our mirrors, from LibreOffice to KDE Plasma and from Gnome to Docker.

Rust 1.75.0 released

Čet, 12/28/2023 - 19:33
Version 1.75.0 of the Rust language has been released. Notable changes include "async fn and -> impl Trait in traits", a pointer byte-offset API, some compiler performance improvements, and a number of stabilized APIs.

[$] The Linux graphics stack in a nutshell, part 2

Čet, 12/28/2023 - 15:46
Displaying an application's graphical output onto the screen requires compositing and mode setting that are correctly synchronized among the various pieces, with low overhead. In this second and final article in the series, we will look at those pieces of the Linux graphics stack. In the first installment, we followed the path of graphics from the application, through Mesa, while using the memory-management features of the kernel's Direct Rendering Manager (DRM) subsystem. We ended up with an application's graphics data stored in an output buffer, so now it's time to display the image to the user.

Security updates for Thursday

Čet, 12/28/2023 - 15:45
Security updates have been issued by Debian (haproxy, libssh, and nodejs), Fedora (filezilla and minizip-ng), Gentoo (Git, libssh, and OpenSSH), and SUSE (gstreamer, postfix, webkit2gtk3, and zabbix).

Debian statement on the Cyber Resilience Act

Sre, 12/27/2023 - 19:35
The Debian project has completed a general-resolution vote, adopting a statement expressing concern about the Cyber Resilience Act (CRA) pending in the European Union.

Even if only "commercial activities" are in the scope of CRA, the Free Software community - and as a consequence, everybody - will lose a lot of small projects. CRA will force many small enterprises and most probably all self employed developers out of business because they simply cannot fulfill the requirements imposed by CRA. Debian and other Linux distributions depend on their work. If accepted as it is, CRA will undermine not only an established community but also a thriving market. CRA needs an exemption for small businesses and, at the very least, solo-entrepreneurs
