Compared to last month,nothing really changed in the top 20 of the TIOBE index. Only Transact-sql and VB.NET swapped places. This could be due to the holiday season,but I am afraid it is just because nothing much is happening in the language market. Except for the rise of Objective-C,no new language emerged the last couple of years. How much longer do we have to wait for the expected breakthrough of the Scalas,the Darts and the Clojures?

与上个月相比，TIOBE排行榜的前20名并没有什么变化。仅仅是Transact-sql和VB.NET交换了位置而已。这可能是由于假期的原因引起的，但是我想这仅仅是因为在编程语言市场并没有太大的变化发生所导致的。除了Objective-C的继续提升，在过去的几年中并没有新的编程语言出现。我们还要花多长时间来等待Scalas、Darts和Clojures语言能有一个飞跃式的突破呢？

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,Amazon,YouTube and Baidu are used to calculate the ratings. Observe that the TIOBE index is not about thebestprogramming language or the language in whichmost lines of codehave been written.

TIOBE编程语言排行榜是流行编程语言的一个晴雨表。这个排行榜每个月都会更新一次。表中的百分比是以世界范围内的有经验的工程师、课程和第三方社区为基础的。也使用了搜索引擎，比如Google、Bing、Yahoo、Wikipedia、Amazon、YouTube和Baidu，来计算这个百分比的。正是由于这样，TIOBE排行榜不是对于最好的编程语言和使用行数最多的代码的语言而建立的。

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.

这个排行榜可以用来检测下你的编程技能是不是跟得上时代，或者是当你开始做一个新的软件系统的时候，可以用来帮助你来确定采用那种编程语言。
