http://www.tiobe.com TIOBE排行榜是根据互联网上有经验的程序员、课程和第三方厂商的数量，并使用搜索引擎（如Google、Bing、Yahoo!、百度）以及Wikipedia、Amazon、YouTube统计出排名数据，只是反映某个编程语言的热门程度，并不能说明一门编程语言好不好，或者一门语言所编写的代码数量多少。TIOBE开发语言排行榜[1]每月更新一次，依据的指数是基于世界范围内的资深软件工程师和第三方供应商提供，其结果作为当前业内程序开发语言的流行使用程度的有效指标。该指数可以用来检阅开发者的编程技能能否跟上趋势，或是否有必要作出战略改变，以及什么编程语言是应该及时掌握的。观察认为，该指数反应的虽并非当前最流行或应用最广的语言，但对世界范围内开发语言的走势仍具有重要参考意义。

Most of them arefrom the US and China, but there are also Japanese and even aBritish and Brazilian website in use now. An overview of all searchengines used can be found on the TIOBE index definition page. Thenew search engines will count only for a marginal fraction of thetotal. Next month we will complete the number search enginestogether with an explanation why these are chosen. C and Objective-C are the biggest victimsof adding the 16 new search engines. They go down -1.65% and -2.17%respectively. Winners are Go (from 42 to 26), LabVIEW (from 100 to49) and Openedge ABL (from 129 to 57). The TIOBE Programming Community index is anindicator of the popularity of programming languages. The index isupdated once a month. The ratings are based on the number ofskilled engineers world-wide, courses and third party vendors.Popular search engines such as Google, Bing, Yahoo!, Wikipedia,Amazon, YouTube and Baidu are used to calculate the ratings.Observe that the TIOBE index is not about the best programminglanguage or the language in which most lines of code have beenwritten. The index can be used to check whether yourprogramming skills are still up to date or to make a strategicdecision about what programming language should be adopted whenstarting to build a new software system. The definition of theTIOBE index can be found here.
