[$] Git considers voting to determine its LLM policy

One of the dominant themes of 2026 has been the debate within development projects about the terms under which LLM-written contributions should be accepted — if, indeed, they should be accepted at all. The Git project has not been immune to this trend; the topic was discussed at the recent Git Contributor's Summit. In this case, the path to a resolution may be somewhat circuitous; the project, which has never been governed as a democracy, is considering adopting a voting process as a way of bringing the discussion to an acceptable conclusion.

Kernel prepatch 7.4-rc2

Linus Torvalds has released the 7.4-rc2 prepatch and it will come as no surprise that it is a large one ("a big -rc2 to go with the largest ever -rc1"). Much of the size was made up of some automated Coccinelle updates that were spread out all over the tree; once those are factored out, the rest looks fairly normal: When masking that noise out from the diffstat, the shape of it changes - not spread out over thousands of files any more. But it does not look unusual: a third is drivers (gpu, networking and sound account for most of it, but there's a bit of everything), another third is networking and bpf, and the final third is "the rest" (mostly filesystems, mm, arch updates). And yes, much of this was driven by various AI fixes. I think I'll stop repeating that, and we can just take it for granted. But this time around Alexei [Starovoitov] claims that on the bpf side at least the fixes are now coming in faster than the new reports, and that sounds lovely if true.

OpenIndiana 2026.10 released

Version 2026.10 of the OpenIndiana operating system has been released. OpenIndiana is based on Illumos, which in turn was based on OpenSolaris after Oracle discontinued it. Notable changes in this release include UEFI framebuffer support for the live image, updates to many applications and development tools, as well as the inclusion of new applications such as TeX Live 2026, the Foliate ebook reader, and more.

ChaCha AVX-512 Optimization For Linux 7.5 Yields Up To 99% Improvement On AMD Zen 5

The Linux kernel's ChaCha symmetric stream cipher code has long had an AVX-512 optimized code path but it was catering to the early generations of Intel CPUs with AVX-512 (Skylake) that suffered from down-clocking under use. But now slated for arrival with Linux 7.5 is tuning the code to perform better on today's AVX-512 Intel and AMD processors that don't suffer from this limitation. In turn the ChaCha performance is as much as 99% faster with current-generation AMD Zen 5 processors...
