Django snippets: Smart {% if %} template tag.
Chris Beaven's drop-in replacement for Django's {% if %} tag that adds comparison operators (less than, greater than, not equal etc) while staying backwards compatible with the less able original. I love it. This is one place where I no longer favour Django's stated philosophy: I think it's perfectly reasonable to use comparisons in presentation logic, and I've found that in my own code the lack of an advanced if tag frequently leads to pure presentation logic sneaking in to my view functions.
Combine JSONP and jQuery to quickly build powerful mashups. jQuery’s JSONP support is one of my favourite little-known features of the library.
