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:

Latency numbers every programmer should know

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

Open in Chrome from Safari and vice versa
-- from http://www.tuaw.com/2011/03/14/use-applescript-to-open-current-safari-url-in-google-chrome/
-- install FastScripts http://www.red-sweater.com/fastscripts/ and place this AppleScript in the Scripts applications folder for Google Chrome.
-- For me that was ~/Library/Scripts/Applications/Safari
-- You can then assign it a keyboard shortcut. I went with Cmd-Shift-C
property theURL : ""
tell application "Safari"
set theURL to URL of current tab of window 1
end tell
tell application "Google Chrome"
