case1：字节码执行

同样的python代码，经过cython编译后运行，一般情况下也比用python解释器运行要快。

因为python解释代码，本质上就是一个for/switch，对字节码的逐条执行，相比机器语言， 使得CPU无法预判指令分支，也破坏指令缓存的局部化。

vimdiff cheat sheet

##git mergetool

In the middle file (future merged file), you can navigate between conflicts with ]c and [c.

Choose which version you want to keep with :diffget //2 or :diffget //3 (the //2 and //3 are unique identifiers for the target/master copy and the merge/branch copy file names).

:diffupdate (to remove leftover spacing issues)

:only (once you’re done reviewing all conflicts, this shows only the middle/merged file)
