Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Real World Specification

(aka "Algebraic JavaScript Specification")

This project specifies the behavior of a number of methods that may optionally be added to any object. The motivation behind this is to encourage greater code reuse. You can create functions that just rely on objects having implementations of the methods below, and in doing so you can make them work with a wide variety of different, but related data structures.

Definitions

For the purposes of this, spec, an "entity" is an object that has an [[equivalent]] operation (see bellow) and may implement some or all of the other methods.

Advanced SCSS

Or, 16 cool things you may not have known your stylesheets could do. I'd rather have kept it to a nice round number like 10, but they just kept coming. Sorry.

I've been using SCSS/SASS for most of my styling work since 2009, and I'm a huge fan of Compass (by the great @chriseppstein). It really helped many of us through the darkest cross-browser crap. Even though browsers are increasingly playing nice with CSS, another problem has become very topical: managing the complexity in stylesheets as our in-browser apps get larger and larger. SCSS is an indispensable tool for dealing with this.

This isn't an introduction to the language by a long shot; many things probably won't make sense unless you have some SCSS under your belt already. That said, if you're not yet comfy with the basics, check out the aweso

on.js

The fun part of user scripting is deciding what happens. The boring part is scavenging the DOM for bits of templated data, or elements you want to mod.

Have on.js do it for you!

This gist was writen in 2012 and it was solving specific problem in Rails & SimpleForm. Some fellow developers were pointing out this may be out dated concept. That's why I advise everyone to read comment section bellow to have a full grasp of alternative solutions
