Optimised async loading of cross-domain scripts
/*
* Updated to use the function-based method described in http://www.phpied.com/social-button-bffs/
* Better handling of scripts without supplied ids.

* N.B. Be sure to include Google Analytics's _gaq and Facebook's fbAsyncInit prior to this function.

This gist demonstrates some uses of the new sass feature: Passing content blocks to mixins.
@mixin ie6 { * html & { @content } }
#logo {
background-image: url("/images/logo.png");
@include ie6 { background-image: url("/images/logo.gif"); }
}

# Only needed if you are using Terminal.app (iTerm has mouse support)
Install http://www.culater.net/software/SIMBL/SIMBL.php
Then install https://bitheap.org/mouseterm/

A simple snippet you can add to your bookmark bar (insert javascript: in front) to measure rendering performance of a state of a webpage
javascript:(function (window,$,runs) { var t = new Date(), i = 1, timetaken,offset = $(window).scrollTop(); $(window).bind('scroll.scrolltest',function () { if (i >= runs) { timetaken = (new Date) - t; console.log('Time taken for '+runs+' scrolls: ',timetaken,' - time per scroll: ', timetaken/runs); $(window).unbind('scroll.scrolltest'); return; } i++; doScroll(); }); function mod (x,y) { return Math.round((x/y - Math.floor(x/y)) *2); } function doScroll () { setTimeout(function(){ $(window).scrollTop(offset + mod(i,2)*100); },0); } doScroll(); })(window,jQuery,500);

Prevent zoom on focus
// * iOS zooms on form element focus. This script prevents that behavior.
// * <meta name="viewport" content="width=device-width,initial-scale=1">
// If you dynamically add a maximum-scale where no default exists,
// the value persists on the page even after removed from viewport.content.
// So if no maximum-scale is set, adds maximum-scale=10 on blur.
// If maximum-scale is set, reuses that original value.
// * <meta name="viewport" content="width=device-width,initial-scale=1.0,maximum-scale=2.0,maximum-scale=1.0">
// second maximum-scale declaration will take precedence.
// * Will respect original maximum-scale, if set.
// * Works with int or float scale values.
