An Ode to Bzip
lz4 can still be the right choice when decompression speed matters. It's almost twice as fast at decompression with similar compression ratios to zstd's fast setting.

Docker Image Compression: gzip vs zstd
So why would anyone compress an image again by using gzip or zstd?

Removing newlines in FASTA file increases ZSTD compression ratio by 10x
This is because Zstd's long-distance matcher looks for matching sequences of 64 bytes [0]. Because long matching sequences of the data will likely have the newlines inserted in different offsets in the run, this totally breaks Zstd's ability to find the long-distance match.
Ultimately, Zstd is a byte-oriented compressor that doesn't understand the semantics of the data it compresses. Improvements are certainly possible if you can recognize and separate that framing to recover a contiguous view of the underlying data.

I ported pigz from Unix to Windows
Perhaps it's worth it adding this as a note at the top of the post, maybe mentioning alternatives, such as an Actually Portable™ build of `pigz`[1] or just a windows build of zstd[2].

Why do I find Rust inadequate for text compression codecs?
If zstd give you an error and you don't handle it, the next calls may cause UB, so it kinda does both things.

Lzbench Compression Benchmark
( https://github.com/facebook/zstd/releases/tag/v1.5.6 )
In my opinion, it is better to check the original repository: https://github.com/inikep/lzbench

DeepSeek releases Janus Pro, a text-to-image generator [pdf]
This. Even their less known work is pretty solid[1] ( used it the other day and was frankly kinda amazed at how well it performed under the circumstances ). Facebook/Meta sucks like most social madia does, but, not unlike Elon Musk, they are on the record of having some contributions to society as a whole.

New standards for a faster and more private Internet
I don't think so? It's only seekable with an additional index [1], just like any other compression scheme.
