Data generated on Fri Mar 7 11:44:08 2008
Welcome to LUI. This page is a compilation of various sources of data concerning programming language usage. Instead of intertrepeting, it simply provides a few metrics that might be useful to others considering the question of language "popularity".

LUI is generated by a small and simple framework written in Perl. It can easily be extended or modified. The source can be downloaded here (zip).

Raw data for some or all of the below metrics can be downloaded in CSV format: raw.csv
