Neat.

When I saw the subject line, I thought you were going to say something
scary, like Matz had decided to drop Ruby and devote his time to Java 1.6.

No, that's because the PRNG changed with 1.7.x

If you are using 1.6.7, you are missing a few nice features.

Yes, I first heard that Halloween was Christmas from Richard
Hamming (of Hamming Code fame). Not directly of course. He wrote
the coding theory textbook I used in college.

yeah, I know ... :-/ But I'm just too lazy to reinstall Ruby on all
the boxes I happen to use.

Wow ... Hamming code reminds me my Crypto&Coding course I had 2 semesters
ago - quite impressive material (and I must admit it was hard time for me
- trying to learn/understand all the things). Please, is that textbook
available somewhere on the Net?

Hmm, not that I know of.

I still have it on my shelf, though. _Coding and Information
Theory_, Richard Hamming.

Great book, interesting topic, and yes, sometimes it's hard to
understand.

nothing scarier than Enumerable#inject though...

(0..67).inject(3709168338536711372250064398972826945394701253532720163819002017081215416156693026){|i,x|print
"o! _,\\`\n/^.>b<"[i%16,1];i>>4}

I'm sure it is... but it doesn't work for me. (self.wtf?)

I pasted quite carefully, too.

This is ruby 1.8.0 (2003-08-04) [i686-linux-gnu]
All I get is a bunch of nils...

Hmmmm.

Hmm... under ruby 1.6.7 this prints:
HHypao!new llpea

Which I don't think was what you meant... ;-)
It works in 1.8 though.

well, in 1.8 we are using mersenne twister as the PRNG
