| 现在网上有许多题库，大多是可以在线评测，所以叫做Online Judge。除了USACO是为IOI准备外，其余几乎全部是大学的ACM竞赛题库。 | |

一直都喜欢用markdown记录东西，即使平时用的某云笔记并不支持markdown，也还是习惯保持markdown格式的记录。最近Medium比较火，就试着把之前写好的一篇文章发到Medium上去，结果Medium并不支持Markdown，可是在Medium上写作的Geek们自然有办法：
就是在这里看到了Github的Gist原来可以这么玩，忽然好奇Gist是不是还有其他好玩的玩儿法。一发不可收拾，果然找到了各种花样玩儿法：
总得来说还是对Gist写东西比较感兴趣，有版本控制，能够设置成别人可见或不可见，还支持协作。Gist写好之后可以通过roughdraft.io发布出来，读起来很方便。
