TL;DR

In Ember, always use {{...}}, not {{{...}}}. Use Ember.String.htmlSafe as necessary in JavaScript (usually in a component) to mark markup as HTML-safe. Never pass user-entered content directly to Ember.String.htmlSafe.

Details

Ember has great XSS protection built in. The HTMLBars templating library will automatically run any interpolations through htmlEscape for you. So

WebSockets - An Introduction

WebSockets is a modern HTML5 standard which makes communication between client and server a lot more simpler than ever. We are all familiar with the technology of sockets. Sockets have been fundamental to network communication for a long time but usually the communication over the browser has been restricted. The general restrictions

• The server used to have a permanent listener while the client (aka browser) was not designated any fixed listener for a more long term connection. Hence, every communication was restricted to the client demanding and the server responding.
• This meant that unless the client requested for a particular resource, the server was unable to push such a resource to the client.
• This was detrimental since the client is then forced to check with the server at regular intervals. This meant a lot of libraries focused on optimizing asynchronous calls and identifying the response of asynchronous calls. Notably t

Ruby, RVM and Mountain Lion

Key problems

Mountain Lion (10.8) has three main difference compared to Lion (10.7):

• XCode 4.4 does not install Command Line Tools by default
• X11 isn't available anymore
• The installed version of OpenSSL has some bugs

How to work around
