### How To Enter Equations Quickly In Class?

Learn to use some macros (823 comments)

I regularly take notes in my advanced undergraduate math classes using LaTeX. The key is to (a) use macros --- make them up on the fly and just start using them. e.g. \pd{f}{g} for \frac{\partial f}{\partial g}, for instance, or \cF for \mathcal{F}, or \sHom for \operatorname{sHom}... (b) don't compile --- compiling during class will just confuse you. Make sure you've got enough info in the .tex file for you to understand what the notes are, and then fix typos and errors afterward. To tie back to (a), actually write the definitions for your new set of macros after class. (c) use Emacs --- if you're doing a lot of TeX you'll be happier with emacs and auctex. (d) type faster. If you can't go fast enough (or the lecturer is whipping through the blackboard faster than you can type), go back to paper & pencil. It's not that bad.

### The Next Round in the Virtualization Wars

Actually, Xen 3.0 with hardware virtualization support on your CPU can run Windows just fine. In HVC mode, getting Windows to run under Xen is actually pretty easy. I have a computer on a desk next to me that is running Windows XP under Xen right now.
