Python main() functions
All Things Pythonic Python main() functions by Guido van van Rossum May 16, 2003 Summary For Python programmers, I've got some suggestions on how to write a main() function that's easy to invoke in other contexts, e.g. from the interactive Python prompt when you feel like experimenting. I've written a few main() functions in my time. They usually have a structure roughly like this: """Module docst

John Resig - Partial Application in JavaScript
Partially applying a function is a, particularly, interesting technique in which you can pre-fill-in arguments to a function before it is ever executed. In effect, partially applying a function returns a new function which you can call. This is best understood through an example: String.prototype.csv = String.prototype.split.partial(/,\s*/); var results = "John, Resig, Boston".csv(); alert( (resul
