I'm guessing whoever manages to implement a subset of <a href="https://en.wikipedia.org/wiki/PAQ" rel="nofollow">https://en.wikipedia.org/wiki/PAQ</a> in JS is probably going to win.<p>Of course, the decompressor itself also needs to be compressed, which I suspect will be where most of the competition will happen.
Hi! I created that challenge but didn't see this HN page until now :) That's where all this traffic comes from!
If you think 30 min is too short for decompression, I can change that rule. Just let me know.
another good challenge would to be trying to display them in the most interesting way possible in under x bytes, demoscene style. But I suppose that's a different audience.
