Hi, tool author here. Huffman coding is a static minimum-redundancy code. What this means is that it finds an optimal assignment of bit sequences to letters in the input alphabet (…

Hi, tool author here! Thank you for your benchmark! As you may be aware, different compression tools fill in different data type niches. In particular, less specialised statistical…

Hi, tool author here! Regarding your first remark: high ratio data compression has its time and place, and I personally understand that to many people it is not very desirable. In …

Hi! Tool author here. Almost every single open source compression tool contains a clause like this. For example, the one in the README that you see has been directly lifted from th…

they're looking for a compressor that can do more than 200MB/s on a 10mW machine (that's including radio, so it has to run on a CPU clocked like original 8086) and yield 200x size …

Yeah, I can kind of relate, actually! Now I am 19, have a job and attend a somewhat demanding university, outside of (more useful?) real world research I am currently doing. I wrot…

Thank you for the kind comments! Unfortunately, the BLC interpreter is much slower than MalbolgeLISP, even when using fast20 (with a lot of optimisations coined by dzaima). My memo…

hi, most of the code in my repository has to work around various C problems (e.g. no generics), so match32 and match64 are the same functions that work on differently sized buffers…

I'm sharing a tool that I have been working on in hopes that someone finds it useful. The tool serves the purpose of binary patching in game updates and personal incremental backup…

I haven't figured a libsais fix and my LZP fix changes the functionality a little (removes chunking for better compression at a rather small runtime cost), so I don't think the aut…

You've literally tested it on a single file, enwik8. That's not enough to extrapolate valuable results. One of the benchmarks: time ./bsc e ../linux.tar linux.bsc -e2 -b16 -T 68.69…

Consider using `-c`, which makes the compressor use standard streams, or pull the main branch because I had just pushed a tiny patch that automatically enables it when no positiona…

lies. not specifying -e displays an error message: % bzip3 -e -j 6 -b 50 corpus/calgary.tar % bzip3 -j 6 -b 50 corpus/calgary.tar bzip3 - A better and stronger spiritual successor …

it's `bzip3 -e -j 6`. you need a space.

no compressor tests the output while compressing as it hurts the performance. you can do it after compressing, though, using `bzip3 -t`.

Frankly, same holds for gzip. I've been planning to relicense bzip3 with the more permissive LGPLv3.

it's fairly common, at least in the circles i usually dwell in, to call compression ratio "compression _strength_". bzip3 is _better_ than bzip2 since it uses a better technologica…

bzip3 usually operates on bigger block sizes, up to 16 times bigger than bzip2. additionally, bzip3 supports parallel compression/decompression out of the box. for fairness, the be…

... maybe :). A while ago I published a writeup on programming in the Seed language ( https://esolangs.org/wiki/Seed ) and made the best Mersenne Twister cracking program to date (…

yes!

I think that you never touched Malbolge yourself. > anything can be trivially transpiled to any turing-complete language regardless of the "difficulty" of the language once basic o…

You're free to run this with alternative Malbolge Unshackled interpreters to verify it (although you'd probably be better off using an optimised one, that fixes to some rotation wi…
