This is wildly off topic, but since the Haskell community is a rather academic one I thought there might be a good chance to find someone who can point me in the right direction. I was just listening to Brooks' talk at OOPSLA 2007 and in the Q&A part at the end he mentions a paper on increasing entropy in software systems. He mentions the authors' names but I can't quite make it out and Google hasn't been very helpful either. He says the paper “must be 30 years old” and it sounds like he says it's by Les Bellati and Manny Leimann (Lehmann?). As I said, I can't quite make out the names, and the names ring no bells for me. Does anyone on the list know what paper he's referring to? /M -- Magnus Therning (OpenPGP: 0xAB4DFBA4) magnus＠therning．org Jabber: magnus．therning＠gmail．com http://therning.org/magnus What if I don't want to obey the laws? Do they throw me in jail with the other bad monads? -- Daveman
