Down below are my QuantLib and Python notes. It's very much a work in progress.
I am also doing a lot of work with QuantLib on the iPhone.
I've released a few iPhone programs:
T-Lights, goes beyond the standard Lights-Out game.
The free limited version is T-Lite.
DayCount/360 is an iPhone day counter and calculator powered by QuantLib. Incorporates standard daycount conventions.
