Tar fediverse
tar -cvfz fediverse.raw fediverse.tgz`
ls -lh
fediverse.raw 2.048 PiB
fediverse.tgz 1.36 TiB
According to my version of tar(1) it's entirely doable
/me grins 😁

[Перевод] Почему GZIP сыпал исключениями только в жару и в дождь
В квартире стояла летняя жара. Впрочем, ненадолго: хозяин квартиры как раз привез мне кондиционер, и его пора было запускать. Через несколько недель Я писал на C# программу для распаковки gzip-файлов и неожиданно поймал странное исключение, из которого следовало, что архив поврежден. Ситуация выглядела дико: ошибка намекала на поврежденный архив, хотя сам файл не выглядел реально битым. Сказать, что это напрягало значит ничего не сказать...

The story goes like this. ComputerCraft is a mod that adds programming to Minecraft. You write Lua code that gets executed by a bespoke interpreter with access to world APIs, and now you’re writing code instead of having fun. Computers have limited disk space, and my /nix folder is growing out of control, so I need to compress code. The laziest option would be to use LibDeflate, but its decoder is larger than both the gains from compression and my personal boundary for copying code. So the question becomes: what’s the shortest, simplest, most ratio-efficient compression algorithm? I initially thought this was a complex question full of tradeoffs, but it turns out it’s very clear-cut. My answer is bzip, even though this algorithm has been critiqued multiple times and has fallen into obscurity since xz and zstd became popular.
Sembra incredibile ma sono ancora qui a pubblicare dei videi nonostante gli impegni sempre più impegnativi. Merito almeno un singolo applauso.
Speciale 5000 iscritti: come funziona la compressione dei dati che viaggiano su internet. Da Shannon (l'unico Claude di cui potete fidarvi al 100%) agli algoritmi classici, fino ai tre protagonisti della compressione moderna: gzip, Brotli, Zstandard.
E "one more thing": il nuovo OpenZL di Meta.

I was surprised to learn that gzip streams encode which operating system did the compression. I built a little tool, "gzpeek", to inspect this metadata (and more): https://evanhahn.com/introducing-gzpeek/
