"Rebel Code" is an excellent history of the free/open software culture (with emphasis on Linux) from background developments/events in the 60s and 70s to a rich picture of the 90s. Author Glyn Moody not only cites and describes main players like Allman, Stallman, Torvalds, Ts'o,.., but also their intertwinement with market forces and critical events/decisions, e.g. SAP on Linux. While describing relevant technical terms, e.g. virtual memory, to a general audience, market demands, reaction, influential technical developments and possible business models constitute the main view. Moody describes not only successes but also pitfalls in a well balanced way. The book won't enable a project manager to install an open source type environment but would definitely help her/him to understand the necessary philosophy. I very much enjoyed the book, read it very fast and recommend it to anyone with an interest in software, business or collaboration. The book lacks Moody's webaddress and a link list.
