Learnings for Week 23 2010

• Recently needed to ignore some files that were already being tracked by git. This Link helped me out.
  • git update-index —assume-unchanged config/database.yml
• HTML5 ‘type=search’ renders a nice search box and degrades to a simple input in older browsers.
• HTML5 ‘placeholder=text’ renders placeholder text into an input that goes away when you click into it.
• case; when ‘one’, ‘two’; to match ‘one’ or ‘two’ in a Ruby case statement.
• Rails hide_action :action_name in a controller will prevent the action from being routed to.
• jQuery “input” event gets fired when typing, pasting, cutting etc. from an input field.
• jQuery live != livequery plugin. Main difference is live can only bind an event handler to the matching elements, livequery can run a function every time another element matches.
• http://www.quickdiff.com super easy online tool to diff text.
