September Headline: Programming Language D back in the top 20
This month the programming language D hits the top 20, replacing F# that cracked the top 20 for the first time last month. Unlike F#, The D language is not new. It has already been in the top 20 from 2007 till the middle of 2009. Wikipedia gives a hint about the comeback of D: “The release of Andrei Alexandrescu’s book ‘The D Programming Language’ on June 12, 2010 marked the stabilization of D 2.0.” In the charts we can see that the D language is gradually rising again since that date.
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.
