The I Am The Greatest programmer "firmly believes that he is the greatest programmer to have walked the earth and has the three-line version of Tetris to prove it. He spent most of his undergraduate days in the terminal room and only got a degree because he could break security and decrypt the exam answers. Thinks in a mixture of C and assembly language, thinks Real Programmers are sissies, has memorised even the unwritten volumes of Knuth (who he believes sold out the moment he started writing TeX) and has most of the source to obsolete Unix kernels in his room"
The My Favorite Toy Language programmer "knows the solution to the problem. The only problem is, we haven't got a compiler for the language that it should be implemented in. MFTL knows only two languages; his favourite toy language and the language you need to compile its compiler. (If a language can compile its own compiler then it isn't a toy!)."
