TIOBE指数显示，九月份Java的流行度下降了0.25%，C语言重新夺回了第一的位置。Objective-C、Transact-SQL等语言也创下了历史新高，而F#则经历了下滑。
October Headline: Java is losing ground despite its new version 7 release
Java lost almost 1% of its popularity in September. If this trend continues, C will be number one again next month. Other interesting observations are that both Objective-C and Transact-SQL scored new all time highs, Assembly reentered the top 20, Visual Basic.NET gained many places (from #39 to #25), while F# had a hard time (from #23 to #46).
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.
