TIOBE Programming Community Index for May 2011
May Headline: C# and Objective-C remain the strongest climbers
No dramatic changes this month. Both C# and Objective-C score new all-time highs. There is no other programming language that can keep pace with C#'s and Objective-C's increases in popularity of more than 2.5% on annual basis. Lua and Python follow with +0.61% and +0.49% respectively.
The TIOBE Programming Community index is an indicator of the popularity of programming languages. The index is updated once a month. The ratings are based on the number of skilled engineers world-wide, courses and third party vendors. The popular search engines Google, Bing, Yahoo!, Wikipedia, YouTube and Baidu are used to calculate the ratings. Observe that the TIOBE index is not about the best programming language or the language in which most lines of code have been written.
The index can be used to check whether your programming skills are still up to date or to make a strategic decision about what programming language should be adopted when starting to build a new software system. The definition of the TIOBE index can be found here.
