DELTA LAMBDA: Fit 1000 Times More Data on Devices

[tsman]

There are a few videos encoded in ASM that manage to fit several minutes in 64kB!

That is because they're not videos. They're generating all of that on the fly using procedural generation. Instead of storing the finished textures or models, they'll store the steps needed to generate it from scratch using their custom graphics engine.

Make an algorithm which can losslessly reduce the size of any file by JUST ONE BYTE and you'll become a trillionaire.

Yep, then apply it recursively.....

Reminds me of the good old days of Jules Gilbert on comp.compression, although the way he went away and came back in waves always made me suspect it was some kind of silly class project on how to troll usenet some professor used each year.

The Australians here might also remember Adam Clark. I think his company later transformed into a shell company for a gold prospecting scam.

Wonder if they are using something like KGB Archiver (https://en.wikipedia.org/wiki/KGB_Archiver). This archiver can shrink 1GB to 1-10MB but man you are going to spend a good chunk of a day decompressing it

Was thinking about doing a video on this, but the campaign has gone nowhere, so I think best to just let it die.

No. You can't compress any random 1 GB file to, say, 10 MB. Some files will compress others will not. It just happens in a lot of cases that files we wish to compress (e.g. text) are easily compressed.

I don't think KGB Archiver was ever a big thing. It's reported as being very memory demanding at 256 MB, which probably means that no one has run this program in a decade.

If you are looking for  a modern, powerful, memory hungry compression method then Bzip2 is a good candidate:

The main problem these days is video, that's what need to be compressed, which is why they are making claims about video. But it bullshit, because the video is already heavily compressed, that pesky entropy thing. If it worked as they claimed it would be trivial to prove to everyone, and their startup would become an overnight unicorn (billion dollar company).

bzip2 was great 10 years ago (and I used to sit next to Julian at Mozilla in 2009), but xz gets better compression and has been the compressor of choice for many projects since 2013 or so.

They resurrected a scam from the dial-up modem days?

I remember that! They deleted the file on disk and marked the sectors as bad. The "compressed file" was just a header and the FAT links to recreate the file.

That's hilarious. Wish I'd thought of that.
