Here’s an example of my current web app user agent, device, and/or feature detection approach. I tend to inline this in the page header just before the stylesheet as part of the distribution build. A benefit of this approach is that detection is done early without any external dependencies. It’s also straightforward to modify or extend while you…
env = (function() {
var flags = {}, ua = navigator.userAgent, el = document.createElement('div'), video = document.createElement('video'), audio = document.createElement('audio'), root = document.documentElement, i
function flag(names) {
names = names.split(' ')
for (i = 0; i < names.length; i++)
flags[names[i]] = true
}
function classnames() {
var names = [], name
for(name in flags) if (flags.hasOwnProperty(name))

Useful command line stuff
# use `basename [suffix]` to do clever multiple renaming
for file in *.html.pdf; do \
mv "$file" "`basename $file .html.pdf`.pdf";
done
# remove "from" metadata from files on OS X
xattr -d "com.apple.metadata:kMDItemWhereFroms" file
# remove "quarantine" metadata from files on OS X

@2x LESS CSS Mixin
/**
* I converted the SCSS mixin to LESS for the awesome coders like myself in response to a blog post on 37Signals - http://37signals.com/svn/posts/3271-easy-retina-ready-images-using-scss
*
* Update: 2014-08-04 - Updated a long-standing bug where retina images were shown no matter what in the first background-image property.
* - Updated retina media query to be more reliable ()
* Update: 2013-11-13 - Picked up another technique thanks to reading this post from Tyler Tate, auto-fill in the second filename for the retina image, http://tylertate.com/blog/2013/06/11/retina-images-using-media-queries-and-LESS-CSS.html
* Update: 2013-04-16 - Have recently found a few use cases when using a retina pattern from Subtle Patterns on the <body>, this has come in handy
* Update: 2013-04-05 - Some research in the Wordpress Core(http://core.trac.wordpress.org/ticket/22238#comment:5) was pointed out that some tests may be redundant (Thanks @kbav) so I've cleaned these up
* Update: 2012-12-29 - U

Enable HiDPI mode in Mountain Lion w/o Quartz Debug
sudo defaults write /Library/Preferences/com.apple.windowserver DisplayResolutionEnabled -bool YES;
sudo defaults delete /Library/Preferences/com.apple.windowserver DisplayResolutionDisabled;
// by the way, you need to logout and log back in for this to take effect. Or at least that's what
// Quartz Debug says. Who knows, maybe it's lying?
// P.S. Go to [Apple menu --> System Preferences --> Displays --> Display --> Scaled] after logging
// back in, and you'll see a bunch of "HiDPI" resolutions in the list to choose from.
