Cross-domain communications with JSONP, Part 1: Combine JSONP and jQuery to quickly build powerful mashups. Since I needed it for a colleague and therefore searched for it, I'll just bookmark it. JSONP is basically just a convention for JSON services that respond to a callback parameter by passing the generated JSON as a parameter to a function call and using the content of the callback parameter as the function name. This makes the data accessible from domains other than the one from which the actual script comes - normal AJAX does not allow this.

ipdb makes the Python debugger a bit prettier and more user-friendly by integrating the tools from ipython. If you're already using ipython, it might be a good idea to install ipdb as well. Alternatively, you can use pdbpp, which provides similar features without ipython (e.g., you could combine this with bpython).
