Just another reason to learn C if you don't know it already . . .
http://www.theregister.co.uk/2009/01/21/open_source_projects_08/C overwhelmingly proved the most popular programming language for thousands of new open-source projects in 2008, according to license tracker Black Duck Software.
The company, which monitors 180,000 projects on nearly 4,000 sites, said almost half - 47 per cent - of new projects last year used C. Black Duck said 17,000 new open-source projects were created in total. Next in popularity after C came Java, with 28 per cent.
