Ah yes, another riveting tale of how a #Minecraft #mod was saved by the mighty #Bzip, the #superhero of #compression algorithms 🦸‍♂️. Who knew that the ultimate adventure would be trading pixelated fun for tedious file space management? 📦✨ Remember folks, when in doubt, always make sure your personal boundaries for code copying are intact. 🙄

I love playing around with #compression

In this case, it's all text-based data in csv and xml formats.

Size:

32,696,320 202411.tar
 4,384,020 202411.tar.bz2
 4,015,912 202411.tar.zst
 3,878,583 202411.tar.bz3
 3,730,416 202411.tar.xz

zstd was invoked using zstd --ultra -22
xz was invoked using xz -9e
bzip2 was invoked using bzip2 -9
bzip3 has no compression level options

Speed:

bzip2     7,680

#bzip3 is freaking amazing, yo.

Ah, so there was a bzip1 (technically, bzip 0.21):

Trabalhando com o tar no linux
Os arquivos tarball são distribuições de software livre que mantêm uma estrutura de diretórios, arquivos fonte, um arquivo Makefile, documentação e outros arquivos, encapsulados em um arquivo tar com compressão de dados gzip.

Este método de distribuição de software é muito popular porque os utilitários tar e gzip são muito
