The Music Theory Handbook

I found a very good book about Music Theory. It's the Music Theory Handbook, by Marjorie Merryman (ISBN 0-15-502662-3). It's a thin book that has lots of good things, including what I need!

Bluetooth

I was trying to get Bluetooth software to work these days. It's very complicated. And the documentation from software APIs is poor. And the documentation from hardware manufacturers is terrible. The examples are incomplete. The problem with Bluetooth doesn't seem to be related to the hardware. It seems to be related to the terrible software. The intention is good, though. The profiles are a nice idea. I just with they worked.

Topological spaces

"For any algebraic objects we can introduce the discrete topology, under which the algebraic operations are continuous functions. This leads to concepts such as topological groups, topological vector spaces, topological rings and local fields."
Kool! That means I can have a discrete topology and define continuous functions in it. And the continuous functions are the algebraic operations. And there's more: any function from a discrete topological space to another topological space is continuous.
