Here is a collection of useful sites/tools/plugins (i.e. permalinks) that I recommend all developers/designers use.

Browser Plugins

• jQuery Shell
• Firebug
• Web Developer
• Measure It
• Color Picker

jQuery used to make random colors:

var colors = ["#009900", "#990000", "#000099", "#999900", "#009999", "#990099"];
randno = Math.floor ( Math.random() * colors.length ); 

$(".entry a").hover(function(){
  randno = Math.floor ( Math.random() * colors.length ); 
    $(this).css("color", colors[randno]);
}, function () {
    $(this).css("color", "#000000");
});
