Install OS X 10.10 Yosemite in VirtualBox

Due to the high usage of this guide and the lack of comfort in Gist's commenting area, I decided to make a blog post out of this which you can find here:

Rebase "web-123-my-branch" onto master:

if you're the only person who is working on a branch...

$ git checkout web-123-my-branch # make sure you're on the right branch
$ git fetch # update remote refs
$ git rebase origin/master # perform the rebase onto the current state of master
  # for each conflict, edit file, resolve conflicts, git add -u <file>, git rebase --continue
$ git push -f origin web-123-my-branch # overwrite remote branch with newly rebase branch

Postgres Cheatsheet

This is a collection of the most common commands I run while administering Postgres databases. The variables shown between the open and closed tags, "<" and ">", should be replaced with a name you choose. Postgres has multiple shortcut functions, starting with a forward slash, "". Any SQL command that is not a shortcut, must end with a semicolon, ";". You can use the keyboard UP and DOWN keys to scroll the history of previous commands you've run.

Setup
