So some programmers (specially C programmers, it seems) have this terrible habit of writing very short-named variables. Then in order to understand the code, you need to decipher the meaning of each variable. Example:

```
unsigned int i, n, h, mw, my, ty;
```

This is from one of the "Suckless" projects by the way. They pride themselves in having small number of code lines so this is probably why.
