if (isCompressed(file)) {
return file;
}
return compress(file);

That's not how entropy works, you idiot.

Even Silicon Valley mentions this at one point. OP could have literally learned why this doesn't work by watching a comedy on HBO. The absolute state of Jow Forums

I can compress 20 GB chunks in up to 256 kB. I'm still working on decompressing them.

compress the black hole

link me some reading material so I can understand pls I am dumb fuck.

You could try to generate all possible files that can be generated with that hash and then using an AI to filter out (gigglamesh

redpill me on gz vs bzip vs xz

Usually compressing a file once w/ the default settings is the best way to go right? Isn't default default for a reason?

No, not necessarily.
They defaults are normally a good balance between compression ratio, and resources (CPU, memory usage, time) to decompress.

They just use compression algorithms.
As far as I'm aware, xz has the best compression ratio.

you can do it, i believe in you

CSV and Excel files?

why don't we see innovation in compression algorithms anymore?

We do; there are constant improvements in compression techniques. Look at some of the tools that can produce zlib compatible bitstreams that are far more compact than have ever been possible before.

For new compression families, look at rzip and then lrzip investigating preprocessing techniques, zpaq with the ability to include bytecode defining custom decompression techniques, and ztandard showing how to scale a compression system from fast/light to slow/compact.

Long range deduplication is also going in an interesting direction, with packages like bup that can efficiently deduplicate segments of files over a huge corpus.

Just because you aren't paying attention, doesn't mean things aren't happening.

there's new algorithms coming out all the time, what are you talking about?

i don't know, it used to be a much bigger deal back in the day, probably because hard disk size was so limited
thanks for bringing me up to speed

i just recently switched my btrfs volumes over to zstd

I can compress chunks of up to 4GB into 8 bytes and also decompress them.

get some compression socks

I use CRC-32 compression. When I want the file back all I have to do is test all the possible entries until I get the same hash back. This also makes file sharing WAY easier.

Here's a copy of my favorite french secret sex pervert movie.
CRC32: FEC9E05C

That 0 byte file is a self extracting archive already. chmod +x and go.

That will work only if Pi is normal, which haven't been proven: math.stackexchange.com/questions/216343/does-pi-contain-all-possible-number-combinations

>not using pifs to store your files as indexes of pi

Does Pi contain itself?

If so it's not fully compressed

If it doesn't it doesn't hold all series of numbers

>using a byte to store the index of a byte in pi

You'll need to use at least two-byte chunks to compress anything, but that will drastically increase (de)compression time. I'd like to see a form of movie piracy where everyone shares indexes of pi instead of torrent hashes and people run this decompression algorithm for months to find the movie.

I suppose it only holds all finite series of numbers.

It only contains all finite series. Pi is fully compressed, it's just that this number with this algorithm won't result in any meaningful compression.

really dumb. you have to use the golden ratio, because that mathematically uses the least compression cycles to achieve the greatest compression.

Could a hash of CP considered illegal?

How did you acquire this hash?

What makes you think I'm the same person who posted the hash?

compress another thing to create another black hole and throw it in the direction of the other black hole. this will probably not solve the problem but it will be cool to watch both black holes colliding.
