Unofficial Twitter Bootstrap Documentation

Unofficial Twitter Bootstrap Documentation
http://unofficial-twitter-bootstrap-documentation.com/

The current project I am working on is running bootstrap 2.0.2 and after the release of 2.1.0 the online documentation for 2.0.x was gone.

I went ahead and compiled the archive docs from the bootstrap github repo into a single site - hopefully others find it useful.

Rails - ActiveRecord created_by and updated_by gem

Often your application will want to track who created and updated your data.
On a previous rails 2 project I used a plugin called userstamp which worked well, but until recently it did not support rails 3+

I didn't find any other gems out there at the time, so I put together the clerk gem,
you can install it as a gem in your rails 3+ applications by adding gem 'clerk' to your Gemfile, see the README on github for details

NOTE: the current version relies on your database tables having columns named created_by_id and updated_by_id and the gem does not support any custom configuration.

postgres: terminate all database connections

Using psql from the command line you can terminate all connections to a database

Comes in handy when you want to do things like restore your staging or development database

Inspect all jQuery events on an element

Very useful

$("SELECTOR").data("events");


All bound event handlers are stored in the elements data context under the events key
This can be very useful when debugging with tools like FireBug

$("form").submit(function () { alert('submit form'); });
$("form").data("events");
> Object { submit=[1] }
