Greetings earthlings I just found out that Matt Mahoney's ZPAQ is available as a Debian package for my system. Didn't even make the connection before between his two hats!
I took a database dump of agi.blue (4.1 MB a text file) and ran it through various compressors: *ls -lSrhtotal 9,8M-rw-rw-r-- 1 stefan stefan 580K Jul 29 02:20 concepts.structure.zpaq-rw-rw-r-- 1 stefan stefan 712K Jul 29 02:01 concepts.structure.7z-rw-rw-r-- 1 stefan stefan 731K Jul 29 02:08 concepts.structure.lrz-rw-rw-r-- 1 stefan stefan 817K Jul 29 02:08 concepts.structure.rz-rw-rw-r-- 1 stefan stefan 996K Jul 29 02:22 concepts.structure.gz9-rw-rw-r-- 1 stefan stefan 996K Jul 29 02:22 concepts.structure.zip-rw-r--r-- 1 stefan stefan 1002K Jul 29 02:00 concepts.structure.gz-rw-rw-r-- 1 stefan stefan 4,1M Jul 29 02:08 concepts.structure* As you can see, ZPAQ wins *by far*. Compressing the file with it took a handful of seconds. It seems the king of compression is among us :-) @Matt: Is there any simple way to get even better compression than with ZPAQ 1.0/1.10 (those are the two versions I have) with default options? Also, have there been any attempts to run ZPAQ on a GPU? Would it help?
