The Brainfuck Programming Language:
Brainfuck is the ungodly creation of Urban M¨ller, whose goal was apparently to create a Turing-complete language for which he could write the smallest compiler ever, for the Amiga OS 2.0. His compiler was 240 bytes in size. (Though he improved upon this later -- he informed me at one point that he had managed to bring it under 200 bytes.)

I'm currently doing DDE calls in ActiveStatePerl on Winders, and writing an accounting system in PHP and MySQL... and just looking at Brainfuck makes my head hurt... hurt.. hurt.. Appropriate name.

I would like to see a BrainFuck compiler written entirely in BrainFuck. That would be cool!

I used this as a .signature file for a while:
(hope it survives the html mangling...)
#define P(C,X)case C:printf(#X);break; /* bftoc.c by markv@pixar.com */
main(){int c;printf("char a[9999];main(){char*p=a;");while((c=getchar())>=0)
{switch(c){P(62,p++;)P(60,p--;)P(43,++*p;)P(45,--*p;)P(46,putchar(*p);)P(44,
*p=getchar();)P(91,while(*p){)P(93,});}}printf("exit(0);}");exit(0);}

That seems to have worked, so along the same lines:

Commercial plugs are fine, if they are relevant to the conversation, and if you don't try to pretend to be a consumer. Annoying endorsements will be deleted if you're lucky, if you're not a whole bunch of people smarter and more articulate than you will ridicule you, and we will leave such ridicule in place.
