Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

SSH between Mac OS X host and Virtual Box guest

On Mac OS (host):

Shutdown your VM and do:

VirtualBox > Settings > Network > Add (you will get vboxnet0)

On a terminal ifconfig will show you new interface vboxnet0

VM's Settings > System > check "Enable I/O APIC." VM's Settings > Network > Adapter 2 > host-only vboxnet0

This sets up keybindings in tmux that allow you to copy/paste to/from your OS X clipboard from tmux running inside an SSH connection to a remote host. Partially borrowed from http://seancoates.com/blogs/remote-pbcopy

Forward your clipboard via SSH reverse tunnels

Exposing your clipboard over SSH

I frequently administer remote servers over SSH, and need to copy data to my clipboard. If the text I want to copy all fits on one screen, then I simply select it with my mouse and press CMD-C, which asks relies on m y terminal emulator (xterm2) to throw it to the clipboard.

This isn't practical for larger texts, like when I want to copy the whole contents of a file.

If I had been editing large-file.txt locally, I could easily copy its contents by using the pbcopy command:
