Top programming languages in open source software
2 likes5,733 views
The document discusses analyzing the top programming languages used in open source software projects. It outlines collecting data on projects from SourceForge and Ohloh across different categories, then calculating the percentage of projects using each language to determine the top 10 overall and for various categories. The results show C as the top language overall, and distributions varying between categories, with Java ranking highest in science and engineering and C++ in games. Future work could involve analyzing more data and collecting it automatically.
