Project mention: The XZ attack and timeline | dev.to | 2024-04-17

29. October 2021 At this point Jia Tan pops up, and the first thing we see from him is an innocuous patch to the xz repository, and while a lot of people believe he started out trying his luck with another library also known as libarchive, this is not the case, I would bet it’s more of a backup looking at the dates, being that there are a few days in between as shown in this commit.

InfluxDB

Minizip-ng

0 1,152 8.0 C

Fork of the popular zip manipulation library found in the zlib distribution.
p7zip

13 735 0.0 C

A new p7zip fork with additional codecs and improvements (forked from https://sourceforge.net/projects/sevenzip/ AND https://sourceforge.net/projects/p7zip/).

Project mention: Ubuntu 23.04 (Lunar Lobster) | /r/linux | 2023-04-20

nearly every main distro I am aware of has both available. The reason you still see p7zip is because the CLI incompatibilities vs the newer 7z/7zip executables and the general licensing issues. Most users of "old p7zip" are actually using the actively maintained https://github.com/p7zip-project/p7zip which is updated, supporting unix permissions and zstd and so on.

minlzma

1 340 1.8 C

The Minimal LZMA (minlzma) project aims to provide a minimalistic, cross-platform, highly commented, standards-compliant C library (minlzlib) for decompressing LZMA2-encapsulated compressed data in LZMA format within an XZ container, as can be generated with Python 3.6, 7-zip, and xzutils
TurboBench

10 310 8.9 C

Compression Benchmark

Project mention: Zstd Content-Encoding planned to ship with Chrome 123 | news.ycombinator.com | 2024-02-07

I'm still unconvinced about this addition. And I don't even dislike Zstandard.
The main motivation seems to be that while Zstandard is worse than Brotli at the highest level, it's substantially faster than Brotli when data has to be compressed on the fly with a limited computation budget. That might be true, but I'm yet to see any concrete or even anecdotal evidence even in the issue tracker [1] while there exist some benchmarks where both Zstandard and Brotli are fast enough for the web usage even at lower levels [2].
According to their FAQ [3] Meta and Akamai have successfully used Zstandard in their internal network, but my gut feeling is that they never actually tried to optimize Brotli instead. In fact, Meta employs the main author of Zstandard so it would have been easier to tune Zstandard instead of Brotli. While Brotli has some fundamental difference from Zstandard (in particular Brotli doesn't use arithmetic-equivalent coding), no one has concretely demonstrated that difference would prevent Brotli from being fast enough for dynamic contents in my opinion.
