Sass/Less Comparison

In this document I am using Sass's SCSS syntax. You can choose to use the indented syntax in sass, if you prefer it, it has no functional differences from the SCSS syntax.

For Less, I'm using the JavaScript version because this is what they suggest on the website. The ruby version may be different.

Deploying Rails to Linode

Installing Ruby Enterprise Edition, Apache, MySQL, and Passenger for deploying Rails 3.0 applications.

Get a Linode, and set it up with Ubuntu 10.04 LTS so that you have till April 2013 to get updates. Once the Linode is formatted, boot it and continue on.

Set up an 'A' record in your DNS, pointing to the IP of your Linode. I'm using demo.napcs.com here.

Initial setup

View placeholder_behavior.js
// To get this code to work, simply add a placeholder attribute to any of your inputs.
// This code requires no-conflict jQuery (var $j = jQuery.noConflict();) and Modernizr.
// Also you should add something similar to the following to your stylesheets.
//
// .placeholder{
// color: #666;
// }
jQuery.fn.set_placeholder = function() {
if ($j(this).attr('placeholder') && ($j(this).val() == '' || $j(this).val() == $j(this).attr('placeholder'))) {
You can’t perform that action at this time.
