Nice work - thanks for your efforts! Yeah, the compute complexity for Reed Solomon is generally O(size_of_input * number_of_recovery_blocks) If you don't specify the number of bloc…

Thanks for doing that. > par2cmdline[-turbo] encode: par2 c -r25 test That command is rather unfair to PAR2 - you should add `-b48 -n2 -u` to make the comparison fairer. PAR2 ain't…

You should at least be benchmarking against par2cmdline-turbo instead (stock par2cmdline isn't exactly performance-oriented). Also, you need to list the parameters used as they sig…

Someone made this: https://github.com/manticore-projects/fpng-java Replacing zlib might give you a few percentage points' worth of difference, whilst fpnge would likely be several …

We've already got JPEG-XL as a good replacement format, but some feel that jeopardizing its adoption is a sensible cause.

Why not use fpnge?

If you search up guides on how to upload to Usenet, you'll often find most of the recommend creating split RARs. Uploaders who just transfer scene releases without bothering to ext…

Many older formats, ZIP included, didn't standardise on an encoding, so they just use whatever the local 8-bit encoding happens to be. And if your system charset is different from …

Hopefully that slowly stops being the standard: https://github.com/animetosho/Nyuu/wiki/Stop-RAR-Uploads

I follow the latest stuff but haven't seen anything I'd consider to be "a very large resurgence". Personal opinion: whilst bad official translations certainly exist, most of the ti…

Generally the translator will find a way to work around the lack of a direct equivalent, trying to convey as much of the meaning as possible. Now you may think that these workaroun…

From memory, the original Nyaa was nyaatorrents.org -> nyaa.eu -> nyaa.se

Your experience may be slightly out of date. Fansubbers these days are a tiny shadow of that they used to be. The vast majority of anime piracy these days consists of ripping offic…

A possibility might be that the bigger sites have paid more attention to opsec, and are harder to take down, whilst smaller players may be easier to intimidate. Current Nyaa (nyaa.…

> It's jumped several domains in the past One thing to note is that there's actually two Nyaa sites, so it's important to not confuse the two. The original jumped several domains, …

Very useful. In fact, it speeds up a single instance (i.e. not taking advantage of SIMD) of MD5 by 20%: https://github.com/animetosho/md5-optimisation#x86-avx512-vl...

Faster PNG en/decoders exist though, it's probably just libpng being the most commonly used, but not extensively optimised.

I didn't infer 15% from the way it was written there. But most platforms these days have some form of CRC32 "acceleration". Adler32 is easy to compute so I'm even less concerned th…

I see. Yeah, PAR3 tries to address the 'lots of files' scenario better than PAR2. But updates are problematic. You could 'delete' parts of a recovery file if the data is present. H…
