Inspect all jQuery events on an element

Very useful


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'); });
> Object { submit=[1] }

Get table and column information in postgres

Use the information_schema catalog -

Get table and columns from the public schema

This can be useful, maybe you want to auto generate some text that creates foreign keys based on a naming convention - for instance let's say we have a ruby/rails method called make_fk_unless_exists

The 'code' column would render something like

make_fk_unless_exists :projects, :milestone_id, :milestones
make_fk_unless_exists :tasks, :project_id, :projects
