Instead of implementing its own asset pipeline Phoenix uses Brunch, a fast and developer-friendly asset build tool. Phoenix comes with a default configuration for Brunch and it will work out of the box, but it is very easy to bend it to our needs, add support for various script and style languages, like CoffeeScript, JSX, or LESS.

Brunch has a very good tutorial, but this short guide should be enough to get us started with asset management from the Phoenix perspective.

Installation

Brunch is a Node.js application. A newly generated Phoenix project contains package.json which lists packages for installation with npm, the Node Package Manager . If we agree to install dependencies when running mix phoenix.new, Phoenix will run npm for us. If we don't, or if we change package.json, we can always do this ourselves:

View Moving to Ruby 1.9.1.md

FEBRUARY 28, 2010

Ruby 1.9.1 was released more than a year ago, but the migration to it has been slow. Looking forward to using the new Fiber class(1, 2), sexier functional syntax, and, of course, enjoying the speed, I decided to move a Rails app that I had started recently, to 1.9.1.

Here are a few tips:

Before you start, consider using Ruby Version Manager (RVM) to manage your Rubies and gems. RVM allows to quickly switch between various Ruby implementations (including such exotic implementations as MagLev), keeping a separate gem set for each interpreter. It even allows you to create your own named gem sets (per project, for example), which I find a very cool feature. If you use Mysql, follow the instruction on how to compile the Mysql gem here: [http://rvm.beginrescueend.com/integration/databases/](http://rvm.beginrescueend.com/integration/d

Methods with_scope and with_exclusive_scope in ActiveRecord scope parameters to method calls within the block. They can be nested, and when with_scope blocks are nested, the scope of the inner block is the merge of all the parent scopes:

Previous posts about http://learnyousomeerlang.com: Dog FSM, Cat FSM.

Chapter Errors And Processes is closer to the beginning of the book and deals with core Erlang concepts: error propagation and error trapping.

First off, here is what I wrote to better understand the section that starts with words "the results of uncaught throws, errors and exits in neighboring processes":

Learn You Some Erlang for Great Good by MononcQc is a really good alternative to the two canonical Erlang Books Erlang Programming by Francesco Cesarini and Simon Thompson and Programming Erlang: Software for a Concurrent World by Joe Armstrong, especially when you need to jump into the language quickly. It gives you enough knowledge to build upon reading other people's code, documentation, and coding.

Things taken for granted by Erlang programmers can be confusing to newcomers to concurrent and functional programming. Needless to say, jumping from, say, C# to Ruby is far less adventurous than from any of the two to Erlang. While reading the book I found out that readability of certain
