That's nothing compared to LenPEG 3 http://www.dangermouse.net/esoteric/lenpeg.html

>For the standard test image the new LenPEG 3 compresses the image so efficiently that data storage space is actually freed on the computer right up to the entire capacity of the storage devices

Great work. Ensuring bit-by-bit identical output and compressing an extra 22% is amazing.

I really wish that every single compression-related blog post would stop referencing Silicon Valley.

don't get this one, where is the code and how can I try it out? if it's so good I would assume dropbox have found it instead of doing lepton.

Not. Funny.

It's a joke, as evidenced by:

"When presented with an image, the LenPEG 3 algorithm uses the following steps:

Is the image Lenna? If yes, delete all other data on the computer's storage devices. If no, proceed to the next step..."

It's a "joke". Not a very funny one, though.

I really admire Dropox for open sourcing this, it shows their commitment.

Saving almost a quarter of space for most images stored is something that truly gives a competitive edge. (I say most because people probably primarily have JPEG images).

Especially considering how many images are probably stored on services like Dropbox.

And they just gave it away to their competitors.
