Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

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

Am I doing it wrong?

Dear Rubyists,

I just lost a contract because of my code in a Rails project.

The specific code in question is related to a "posting a comment" feature. Here are the details:

In this project, "posting a comment" does not simply entail inserting a row into the database. It involves a procedure to yes, insert a row, but also detect its language, check for spam, send emails, and "share" it to Twitter and Facebook. I believe this algorithm should be encapsulated. I do not believe it belongs in a controller or a model. I do not believe Active Record callbacks should be used.

The "senior developer", whom is the stake holder's right hand man, said this:
