Useful Stuff

There are a lot of data that I refer to often, but I don't particularly feel like visiting Google every time I need to find them, and I don't want to have to carry my bookmarks around with me on a floppy. Hence, we have Stuff: a quick and easy way for me to find the information I need.

This section is also a holding place for other random things that don't fit anywhere else.
