Finally, Your 50 Character Reward!

Saturday 21 August 2010, 12:15 am   ///////  

After I presented poetry generators ppg256-1 through ppg256-5 at Banff in February, I shouted out, more or less spontaneously, “50 character reward to whoever gives us the best explanation of what ppg256 is!” Why did I say that? Childhood trauma, possibly, but the more immediate reason, as I mentioned earlier, is that the last of these, ppg256-5, is based on a section of Tristan Tzara’s February 1921 Dada Manifesto, one which ends with the phrase “50 francs reward to the person who finds the best way to explain DADA to us.”

I got some great answers, including “It does a lot with a little” (Chris Funkhouser) and “ppg combines atoms of language” (John Cayley). But at this point I’ll skip right to the one from Travis Kirton, who did the following without having any previous experience programming in Perl:

perl -le '@a=split/,/,"illmn,imgn,ltr,mut,pxl,popl,strlz,pnctu,typfc,poetc,glmr,idl,ion,cptl,cpsl,cvl,atom,pltc,txtul,erotc,rvl";sub f{pop if rand>.5}sub w{$a[rand@a]}{print f("de").f("over").w."izes ".w."ation".f("s")."\n".(" "x45)."IS WHAT ppg DOES!";sleep 5;redo}'

The program is a modification of ppg256-5, one that answers the questions that ppg256-5 generates. That’s not only clever; it showcases the expressive power of small programs and the many, if not arbitrary, uses to which a language generator can be put. This certainly earns the reward. Travis, here’s an base64-encoded version of a 32-byte DOS intro, matisse, by orbitaldecay. When you run it after decoding it with a base64 decoder, it should look like this. The base64-encoded string, you will notice, is exactly 50 characters in length:

sBPNEMUPHgeLFwmXQAEJVwFL4vSsQKq5ZQDkYEh16cM=

Okay, I lied. It’s only 44 characters long. Please accept base64 as the remaining part of the prize.

Now, I think Mark Markino’s explanation of ppg256, which I wrote about yesterday, is also great and will suffice. It’s a wide-ranging and deep study of the series of generators, similar programs I’ve discussed, and some relevant contexts of techneculture. I can’t really decide which of these explanations is best, as they both work excellently for what they are. So I am going to offer Mark Marino a 50-character generator, too. Mark, here is an ASCII encoding of a set of tools that, used properly, will allow you to draw any image:

Enjoy!
