Re: NOSSO(r) compression

I just compresses using bzip2, and it only saved 8% versus over 50% saved by using NOSSO(r). Here is the bzip2 output
1.080:1,  7.406 bits/byte,  7.42% saved, 2718433280 in, 2516591511 out.

The command line I used to compress was bzip2 -9zvv sol-10-u4-ga-x86-dvd.iso

Did you try to bzip2  the DVD using -9 options to have something to compare ?

I just downloaded solaris.  They have two versions, the split DVD that
comes with two 1.2GB zipped chunks and an exe which is 1.2GB but
uncompresses to the full 2.5+GB.  I found some info on them here:
http://www.nosltd.com/nosso.html

Any idea how they achieve such great compression?  Looks like they're
using a proprietary algorithm and don't offer any downloads.  Also looks
like it's windows only.  Is there a linux/open source alternative out
there?
