I am writing a game in Python (with pygame) that requires me to generate random but nice-looking "sea" for each new game. After a long search I settled on an algorithm that involves Bezier curves as defined in padlib.py. I now need to figure out when the curves generated by padlib intersect a line segment. The brute force method would b...

I set django's settings.py file to chmod 600 to keep felonious folks from spying my database connection info, but on import python compiles this file and writes out settings.pyc as mode 644.

I'm trying to add a new transport to Twisted, which will read data from a stream - either a file in a tail -f way, or from a pipe, but I have some problems with Twisted architecture.
