The Cathedral and the Bazaar Eric S. Raymond
The Cathedral and the Bazaar describes two approaches to software development. The traditional 'Cathedral' style, where a central architect creates a vision which is implemented by a team of functional but essentially disconnected workers, and the 'Bazaar' style, typical of many open source projects and in particular Linux, where a large groups of equals combine to create a shared vision.
Eric analyses a number of characteristics of the bazaar model and why some traditional theories of software need to be modified in the light of the Linux experience and identifies a number of key lessons including Linus's Law: Given enough eyeballs, all bugs are shallow.
Netcraft conduct an automated monthly survey of internet sites; in January 2005 they collected 58,194,836 responses. These responses can be analysed to show the distribution of different web server software and the operating systems on which they are hosted.
