> Zstandard is a real-time compression algorithm, providing high compression ratios. It offers a very wide range of compression / speed trade-off This would have been very handy about 17 years ago when I was doing a virtual CD-ROM driver, and needed to store compressed images, and the client wanted a wide range of speed/compression options for the user--much wider than zlib offered. I ended up doing a hack that was either the most disgusting thing I have ever done…
Interesting fact that under the hood it's based on tANS introduced by Jarosław Duda from Jagiellonian University: some cool references: https://www.youtube.com/watch?v=uXtmN9fE01k https://th.if.uj.edu.pl/~dudaj/ https://demonstrations.wolfram.com/DataCompressionUsingAsymm... https://encode.su/threads/2078-List-of-Asymmetric-Numeral-Sy...
