Background
Google me http://www.google.com/search?q=alan+ng or go straight to http://www.alan-ng.net/alan/. English abstract: ex-Berkeley physics and IT nerd turned folk musician and cultural historian in Madison, Wisconsin. Deutsch: tja, es muss nicht immer Englisch sein; bei mir kommst Du auch auf Deutsch zurecht.
Opinion
Why E@H: because it was the first BOINC project with a formally developed PowerPC(Altivec)-optimized application to use my Macs efficiently, and because it's good physics.
