LZ4 1.11 brings multi-threaded compression support to the liblz4 library itself, not just the command-line tool. A new configurable field lets applications control the number of worker threads when using liblz4, improving performance on multi-core CPUs. The project's own testing on an AMD EPYC server showed promising results. The lz4 command line tool also gains a '--memory' option to cap multi-threaded compression within a memory budget, alongside other general performance improvements over LZ4 1.10.

Dùng thửHosting providers, platforms, and phone makers should adopt AVIF and AV2 more widely, the author argues. Hetzner raised prices multiple times in 2026 citing rising hardware costs, partly driven by AI demand. AVIF generally compresses better than WebP at comparable quality, and the author has switched to AVIF everywhere it's supported, falling back to WebP otherwise. YouTube is preparing to move from AV1 to AV2 as early as 2027. The author also wants better native support for Apple's HEIC format alongside AVIF, and suggests users encode AVIF locally before uploading to ease server load.

malloc has a very nice and simple interface: you ask for a certain amount of memory, and you’re given a void pointer to your block of contiguous bytes that’s been magicked into existence. Once you’re done with it, you call free with the same pointer and the memory disappears into the ether.

Linus Torvalds released Linux 7.4-rc2, calling it a big rc2 following the largest ever rc1. The release includes a notable FAT32 performance improvement, especially for synchronous mounts, AMDGPU driver fixes for HDMI 2.2 FRL, and numerous fixes for long-standing core memory management bugs. Torvalds noted the diffstat looks benign and is largely driven by automated coccinelle script updates that add noise, and that AI-generated fixes and bug reports continue to pour in. He said Alexei claims fixes on the bpf side are now coming in faster than new reports. Linux 7.4 is aiming for a stable release around the end of December.
