@whitequark @fasterthanlime for my weird needs i ended up storing images in ram as a vec of individual zstd-compressed rows which somehow ended up actually faster to work with than a 20 gb slab of raw pixels. Computers are magic.

CVE-2025-68262 - crypto: zstd - fix double-free in per-CPU stream cleanup
In the Linux kernel, the following vulnerability has been resolved: crypto: zstd - fix double-free in per-CPU stream cleanup The crypto/zstd module has a double-free bug that occurs when multiple tfms are allocated and freed. The issue happens because zstd_streams (per-CPU contexts) are freed in zstd_exit() during every tfm destruction, …

Flatpak Adds Support For Building OCI Bundles Using Zstd Compressed Layers
Back in November Flatpak 1.17 released with support for sideloading from OCI images and other improvements in working toward the Flatpak 1.18 stable release. Out today is Flatpak 1.17.1 and was then followed quickly by Flatpak 1.17.2 to fix a mistake in the release artifacts...

FWIW, you can use the `zstd` binary to train an optimal dictionary automatically, see: github.com/facebook/zst...
Just be mindful of this issue: github.com/facebook/zst... – you can trim the unnecessary bytes and make it valid with `tail -c +5`

oh boy i cant wait to enable zstd compression on my jetstream listener! just gotta download the official dictionary provided on the bluesky github and- oh. oh. okay. yeah no that sounds like bluesky alright.

Some optimization on VBQ with the latest binseq update, especially in lossless mode. Some ways to trim the fat:
1. Reuse zstd decoders for each thread. I was creating a decoder for each vbq block which incurred redundant allocations
2. Zero-copy parsing of blocks, referencing similar to paraseq

Can I use has a strange entry for Zstandard on Safari (https://caniuse.com/zstd). I can’t find many references for it but indeed, if you serve Zstd to Safari >= 26 it does work. There doesn’t even seem to be a feature flag to turn on sending it in the Accept-Encoding header.
