WordCamp Raleigh 2011 featured me talking about how to Debug in WordPress and how to file a bug report for WordPress.  I talked about a number of tools that make debugging easier that everyone should check out.  These tools are:

Xdebug – make your php errors look better and easier to fix

Log Deprecated Notices – Easily see in your admin area when plugins or themes are using deprecated functions, files, and arguments

Debug Bar – Firebug for your WordPress.

Debug Bar Console – add a php and sql console to your WordPress front end
