While open source seems like a "no-brainer" for government use, it turns out that governments can be surprisingly resistant to using FOSS for various reasons. Federico González Waite spoke at SCALE 22x to recount his experiences working with and for the Mexican government. #opensource

Zig is a low-level, memory-unsafe programming language that aims to compete with C instead of depending on it. The 0.14 release contains a number of new convenience features, broader architecture support, and the next steps toward removing Zig's dependency on LLVM. #opensource #zig #programming

There are many challenges involved with running a site like LWN. One of them is the task of fending off bots determined to scrape the entire Internet to (seemingly) feed into the insatiable meat grinder of AI training is certainly one of those. Read on for a description of a modern-day plague.

Recently, there has been a fair amount of attention given to a patch set merged for Linux 6.13 that, it is claimed, can improve processing efficiency (and, thus, power savings) in data centers by as much as 30%. #Linux #Networking

Most Linux systems depend on a suite of core utilities that the GNU Project started development on decades ago and are, of course, written in C. At FOSDEM 2025, Sylvestre Ledru made the case in his main stage talk that modern systems require safer, more maintainable tools.

By the time that Linus Torvalds released 6.14-rc1 and closed the merge window for this development cycle, some 9,307 non-merge changesets had been pulled into the mainline repository — the lowest level of merge-window activity seen in years. #Linux #LinuxKernel

Greg Kroah-Hartman has released three more stable kernels: 6.13.3, 6.12.14, and 6.6.78. There was a bit of confusion that resulted in the patch for CVE 2025-21687 getting applied twice — but that doesn't result in any problems for users of the kernel, just a bit of extra noise in the CVE database.

A "uretprobe" is a dynamic, userspace tracepoint injected by the kernel into a running process. A significant change to uretprobes in #Linux 6.11 improved their performance, but that change is also creating trouble for some users. The best way to solve the problem is not entirely clear. #LinuxKernel
