I’ve written quite a few pages that are separate from the timeline of the blog. These are a little hidden, not because I want to hide them, but because you can’t make everything equally easy to find. These notes cover a variety of topics:

- Math diagrams
- Numerical computing
- Probability and approximations
- Differential equations
- Python
- Regular expressions
- C++
- Special functions
- Typesetting: TeX, HTML, Unicode
- Emacs
- R
- Miscellaneous math

You can find an index of all these notes here.

Some of the most popular notes:

- Diagram of probability distribution relationships
- Stand-alone code for numerical computing
- R for programmers

And here is some more relatively hidden content:

- How to subscribe by RSS or email
- Online calculators
- Journal articles and presentations
