Phew, am tired. It's hard working in these temperatures, but nicer than freezing my bits off. We will be getting air-con in the room soon in preparation for the baby's arrival but right now it's hot!
The stats program is coming on very well thank you! It now handles different types of data with ease and total transparency for the user. The output is nicely formatted and looks good. The architecture seems to be about right and we're looking to release the first version (obviously a beta) maybe next week. It will be under the AGPL because we intend to put in networking capabilities. Complex data analysis through a web-browser? Heh, why not?
Uraeus - I've tried noise-cancelling headphones on long flights and found them to be quite good. If they're the "tighter" ones (ie, the ones that fit tight around the ears) they can also help preventing ears from popping.
