Programming Acronym Glossary

The programming glossary will define some common acronyms and words used by programmers. This document will be updated semi-regularly.

Note that a lot of these definitions are for acronyms that are unrelated to computer science (many are general acronyms for internet chat, like AFAICT). The main reason for this is that I do not regularly chat and am tired of having to infer the meaning of an acronym every time I come across it, so I thought I would remember them better if I wrote them down.

Also note that I did not look up the common use definitions for most of these words. While a vast majority of them are correct, there may be some errors here.
