This gist is outdated

Homebrew people have since included this in a recipe.

$ brew update
$ brew install mongodb

Railties 3.1 Beta 1

The -j option of the application generator accepts an arbitrary string. If passed "foo", the gem "foo-rails" is added to the Gemfile, and the application JavaScript manifest requires "foo" and "foo_ujs". As of this writing "prototype-rails" and "jquery-rails" exist and provide those files via the asset pipeline. Default is "jquery". [fxn]
jQuery is no longer vendored, it is provided from now on by the jquery-rails gem. [fxn]
Prototype and Scriptaculous are no longer vendored, they are provided from now on by the prototype-rails gem. [fxn]
The scaffold controller will now produce SCSS file if Sass is available [Prem Sichanugrist]

Fibur

Fibur is a library that allows concurrency during Ruby I/O operations without needing to make use of callback systems. Traditionally in Ruby, to achieve concurrency during blocking I/O operations, programmers would make use of Fibers and callbacks. Fibur eliminates the need for wrapping your I/O calls with Fibers and a callback. It allows you to write your blocking I/O calls the way you normally would, and still have concurrent execution during those I/O calls.

Example

Say you have a method that fetches data from a network resource:

Routes

小心地使用 Match（Rails 3 已实现）

Rails 3 提供了 match 方法供我们自定义 routes，然而我们要小心使用它以避免“跨站脚本攻击”（XSS Attack）。比如像这样的 routes：

注：（r3 代表 Rails 3，r4 代表 Rails 4）

# routes.rb

	~$ ARCHFLAGS='-arch i386 -arch x86_64'
	~$ rvm install 1.8.7 --debug --reconfigure -C --enable-shared=yes
	~$ wget http://sourceforge.net/projects/rubycocoa/files/RubyCocoa/1.0.0/RubyCocoa-1.0.0.tar.gz/download
	~$ tar xzf RubyCocoa-1.0.0.tar.gz && rm RubyCocoa-1.0.0.tar.gz && cd RubyCocoa-1.0.0
	~/RubyCocoa-1.0.0$ ruby install.rb config --build-universal=yes
	~/RubyCocoa-1.0.0$ ruby install.rb setup
	~/RubyCocoa-1.0.0$ sudo ruby install.rb install

	⌘T – Go to File
	⇧⌘T – Go to Symbol – This works in the same way as Go to File but for within a specific file.
	⌘L – Go to Line
	⇧⌘L – Select Line
	⌃⌘ + ARROW – Move Code
	⇧⌃⌥V – Send selected to Pastie – Send the selected code over to Pastie with a private URL for sharing the code.
	⌃S – Simple Search – Most folks know about ⌘F as it’s the same in most applications. This shortcut allows you to do a quick search in the current file iteratively.
	⌘] and ⌘[ – Block indentation.
	⌥⌘[ - Format Selection.
	⇧⌃T – To-do list – This feature scans the project for code marked as ‘FIXME’, ‘TODO’ and ‘CHANGED’.
