Design Patterns Ed Q. Briges writes: "although it’s probably more technical than most info-architects may be interested in, the “Gang of Four” book is tremendously influential in current software architecture and design circles. In turn influenced by Christopher Alexander’s notions about architecture and designing habitable spaces. After all, coders “live” in the code they’re — more often than not — maintaining. and, the experience of dealing with poorly written software (both for a coder and a user), is not unlike trying to make sense out of a badly designed building or public space. The book itself is very usefully designed, being a highly structured catalog of patterns."
