Those interested, who have read RPG's original article, might want to learn more about his example of "the right thing", PC-lusering, by reading PCLSRing: Keeping Process State Modular by Alan Bawden (http://fare.tunes.org/tmp/emergent/pclsr.htm http://fare.tunes.org/tmp/emergent/pclsr.htm), and then perhaps learn more about ITS, which can still be run on a PDP-10 simulator: http://its.victor.se/wiki/ http://its.victor.se/wiki/ Those who don't want to go too far down that particular rabbit hole could do worse than read the first third of Steven Levy's Hackers, which is about the MIT AI Lab. The reason ITS is rarely used now is more mundane than you might infer from RPG's articles: it was machine specific, being mostly written in MIDAS assembly language, and needs a PDP-10 to run it on, and DEC stopped making them. Unix is written mostly in C and is portable.
