@glasslion 好吧。。今天第一次接触ub，求指教。。。

@glasslion pip install --use-wheel Pillow 了，但是还是同样。。。

测了下是15-25ms之间。用未排序下去做。。。c++初学者。。。不会位运算，第一次想别人的问题，第一次贴出代码。还需努力，见笑了。。。

@reorx 我github和duck一直都很顺畅。谢谢指点

@Livid 我今天是粗略看了下百度，然后看了下duckduckgo，也都每看到。。。坑的没想到去自由国度那边看看，谢livid！我去逛tornado的文档。

@fansgentle 请问tornado的request_time应该怎么实现？

@Livid 请问footer的VERSION: 3.3.2 · xx ms统计的是什么？
在python中怎么实现？
［初学者。。。］

在中国，好像不算什么稀奇

@Ansonyi 有搜过。。。此贴目的在于搜集没有太公开的一些开源。。

@superwbd 底部化繁为简，会比较合适。不然就缩小字号扩大行距

@ericls 这域名碎了吗

@turing 这个以前有看过，做的很不错

@superwbd 不错，就是字体颜色坑了

@missdeer 确实，在质量上面v2ex做得很足。一些提高用户质量的算法也很不错。
逛到http://wehoton.com这个站，看起来还是相对满意得（只从界面功能）。

@WildCat nodeclub好像更像是单节点的社区。
@Ellison 以上的那些功能好像都相近

@WindSays 哈哈，希望theme越出越好～

@WindSays pesi.me 话说我把底部版权信息稍微动了下，应该不会算侵犯权限把。。。
