This has got to be peak <something>. I don't know what exactly, but it's something. Self-inflicted torment and/or eccentric fountain of joy. Probably both.<p>I cannot, for the life of me, see myself investing the time needed into something so futile. But I love that there are people out there who do this kind of thing out of pure joy.
The most awesome random submission I ever received was a BrainFuck compiler written in BrainFuck, by hand. Short story: I wrote a bf compiler in Emacs Lisp many many years ago. As a small testcase, I included a BrainFuck compiler in BrainFuck, which was written by a guy who wrote a C-alike to BrainFuck compiler so that he could implement his BF compiler in BF. That was a strange piece of code, about 6 pages of plain BF. A few years later, suddenly, I have this mail in my INBOX: A norwegian guy sent me a BF compiler in BF, written by hand. He was unsatisfied by the existing BF compiler, as it was generated. His implementation was about 6 lines of BF code. And it was a magnitude faster. Hats off to that guy!
Just a helpful resume tip. If you work on something in Brainfuck, put it on your resume as BF. And don't mention the name of your multi-threaded BF environment.
