Analysis of IORCC Entries?

[Ryan Leavengood]

So, I was been browsing http://iorcc.dyndns.org/ and looking at the 2005
entries for the International Obfuscated Ruby Code Contest (IORCC), and
in the process I've cleaned-up and have a solid understanding of several
of the entries. Would anyone be interested in reading an analysis and
clean-up of these programs, or is that an exercise best left for the reader?

I suppose you could say this was like Ruby Quiz #26 (Code Cleaning),
with me doing the cleaning instead of James.

I find it quite interesting figuring them out, sort of like solving a
puzzle, but maybe others would just like to see how the "magic" happens.

Let me know,
Ryan

I've done these and will post them tomorrow if possible. It would be
wonderful if you had the missing ones done already, but I guess there
will be some overlap:

1-negaposi.html,
3-primes.html,
4-quiz-loader.html,
5-numbers.html,
6-xor.html, (no detailed explanation of the algorithms)
7-slash.html (partially)

I, for one, am very interested in reading anyone's work on this.

Here we go, then: http://flgr.0x42.net/deobfu/

Hope you enjoy and have as much fun reading as I had deciphering them.
