David Bakin's first concurrent program was a Tektronix terminal emulator, written in assembly for an IMLAC PDS-1, which was a PDP-8-like machine with a GPU. He's written a lot of multiprocess and multithread concurrent programs and a number of tools for visualizing and debugging concurrent programs since then. He says computers now are orders of magnitude more powerful than the PDS-1, but concurrent programming hasn't gotten any easier.
His favorite languages are C++ and Haskell, and he prefers to use strong typing and functional programming techniques to write correct code. On the other hand, he also likes Smalltalk, Mathematica, and SIMD code in assembler because they're a lot of fun.
