What aliases and scripts do you use?

As developers we use a lot of alias and small scripts to automate boring stuff. Here is my commonly used alias and scripts. What do you use?

I only use a couple, because I'm not overly keen on aliases.
I use them for cosmetic things, like alias pacman='pacman --color=always'. That's safe, because it's not changing the way I would expect pacman to work on my system, a foreign system or in a shell script.
I also have a couple of hyper-specific things that I put in aliases just because they're too small to bother with making into scripts :)
