TIOBE排行榜

TIOBE排行榜是一个编程语言的热度排行，据说用了25个搜索引擎的数据，结果应该比较权威，具体算法和说明在此。下面是2015年八月的最新数据

August Headline: Java stronger in the leadJava is now almost 4.5% ahead of the rest of the pack. We have to go back to 2008 to see such a big difference between Java and the number 2 of the TIOBE index. Java version 8 is clearly a success. This is mainly thanks to the functional programming idiom that has been added to this latest version. Java went in decline when Oracle bought Sun Microsystems (and thus Java) in 2010. Several Java gurus left the company, being afraid that this was the end of Java. Indeed, Java was verbose and way behind languages such as C# in terms of expressive features. But the doomsayers appeared to be wrong. The first few years nothing much happened to the language, but the release of Java 8 in 2014 is a big leap forward. It is now possible to write Java programs in a functional and concise way. Surprisingly or may be not, Java is consuming a large part of the market share that Objective-C is losing, while Objective-C's successor Swift was supposed to do this.         
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. Popular search engines such asGoogle, Bing, Yahoo!, Wikipedia, Amazon, YouTube and Baidu are used to calculate the ratings.It is important to note that the TIOBE index is not about the best programming language or the languagein 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.
