Hi. My name is David Ho.
I refactored the experimental toolbox.
I'm also trying to edit many of the individual articles within the toolbox. I'd like to add material, but I'd also like to rewrite (and sometimes remove!) things to make the articles more readable. Sometimes you write a better article by subtraction.
...but at the moment I've got 21 hours to finish a CS problem set. =(
I'll probably still try to update more of the articles anyway, just as a way to review. It'll probably be helpful for me.
