Were you really expecting a coverage of mathematics broad enough to include actuarial science? I agree there seems to be a large number of topics useful for graphics programming, but of course the site can't hope to cover every application of mathematics.
The site appears to be struggling, but you can view the Coding Math videos on YouTube [1].
These are really useful. Whether we like it or not, mathematics underpins most of computer science and often beginners don't even know what to search for to get started. A resource like this is an excellent way to get somebody going.
If the site had a page where they listed all of the videos in order, instead of having to go thru pages of (I'm assuming) Wordpress entries, it wouldn't be struggling.
Not that it's not a great idea, just a poor implementation of an "index".
