Clojure In Small Pieces
Rich Hickey invented Clojure. This is a fork of the project to experiment with literate programming as a development and documentation technology. Clojure is a break with the past traditions of Lisp. This literate fork is a break with the past traditions of code development. As such it is intended as an experiment, not a replacement or competition with the official version of Clojure. Most programmers are still locked into the idea of making a program out of a large pile of tiny files containing pieces of programs. They do not realize that this organization was forced by the fact that machines like the PDP 11 only had 8k of memory and a limit of 4k buffers in the editor. Thus there was a lot of machinery built up, such as overlay linkers, to try to reconstruct the whole program. The time has come to move into a more rational means of creating and maintaining programs. Knuth suggested we write programs like we write literature, with the idea that we are trying to communicate th ...
