Bundler 1.3 --binstubs vs. Rails 4

On a clean Rails 4 install with Bundler 1.3.0, using --binstubs causes competition between Rails and Bundler for the contents of bin/rails (and bin/rake).

Just running bundle will rewrite the Rails version of bin/rails to a version that doesn't work.

The fix is to use the new bundle binstubs <gemname> command.

(see rails/rails#8974)

Learn JavaScript concepts with recent DevTools features

Learn JavaScript concepts with the Chrome DevTools

Authored by Peter Rybin , Chrome DevTools team

In this short guide we'll review some new Chrome DevTools features for "function scope" and "internal properties" by exploring some base JavaScript language concepts.

Closures

Let's start with closures – one of the most famous things in JS. A closure is a function, that uses variables from outside. See an example:

$VERBOSE = nil
require File.expand_path('../rooby', __FILE__)
Person = Rooby::Class.new 'Person' do
define :initialize do |name|
@name = name
end
define :name do

The History of Ruby
* Only the releases of the stable versions are listed in principle. The releases of the unstable versions especially considered to be important are indicated as "not stable."
* The branches used as the source of each releases are specified, and the branching timing of them are also shown. BTW, before subversionizing of the repository, the term called "trunk" was not used, but this list uses it in order to avoid confusion.
* In order to show a historical backdrop, big conferences (RubyKaigi, RubyConf and Euruko) are also listed. About the venues of such conferences, general English notations are adopted, in my hope.
* ruby_1_8_7 branch was recut from v1_8_7 tag after the 1.8.7 release because of an accident.
* 1.2.1 release was canceled once, and the 2nd release called "repack" was performed. Although there were other examples similar to this, since the re-releases were performed during the same day, it does not write clearly in particular.
* Since 1.0 was released with the date in large quantities, the mi

Why Haskell is Cool
Haskell is cool!
Here are some reasons why.
(This is a Literate Haskell file, so you can load it and then follow
along with the examples by running `ghci whyhaskelliscool.lhs`)
"Pattern matching" syntax for defining functions is cool, letting you
avoid 'if' statements and simply write out the different behaviors of
a function:
