一、工具
1. 数据抓取
当然，后续的331个项目的明细数据，还是得通过OpenHub的API来抓取。
2. 数据分析
完全是土法上马：sqlite3+numbers+csv+ruby，反正各种手法，什么称手用什么。
3. 数据展示
二、释疑：项目大小与创建时间的关系
我与@云风 在微博上有一小段讨论，起因还是我之前的一些分析的观点：
- 是否使用Github，越是新的项目越愿意用；越是大的项目越没法用。
- 是否使用Github来管理项目的issue，越是新的项目越愿意用；越是大的项目越没法用。
这个结论，其实在用词上，是有些讲究的：按理说，新与老相对，小与大相对；愿意与不愿意相对，能用与没法用相对，我的两个结论，对仗都不公整。其实，确实故意为之。
后来，我也没有再继续这个讨论，但是却一直在思考这个问题：「项目的大小，与项目的创建时间，究竟有大少相关性？」
后来，我将两个数据，做了一个分析：Log(第一次提交代码，至今的天数)/Log(代码行数)，大概得到如下一个图：
经过强大的Excel的计算，两个数据的相关系数，大约是0.203的样子，也就是说：大致上有较弱的正相关。
