the popularity of programming languages：
提醒自己：
1、2004-5，Java让出No：1的位置。C语言在本月（2005-1）仍然是最受关注的语言。
2、在Java/C++大幅下挫时，Python/Peal大幅上扬。反动明显。
3、PHP获得
2004年程序语言奖。
4、
动态语言开始受到关注。
5、C＃仍然在蓄势？鸡肋？

8、The ratings are based on the world-wide availability of skilled engineers, courses and third party vendors. The popular search engines Google, MSN, and Yahoo! are used to calculate the ratings. Observe that the TPC index is not about the best programming language or the language in which most lines of code have been written.
9、 Jython可能成为Python的替代品？
Jython is a version of Python written in Java and designed to run under the JVM.

10、 why Java dropped so heavily this year？
Benjamin Ferrari ："[...] one reason for Java slipping could be that it is not treated as a 'language for everything' anymore.". （yes，i agree。）
