I haven't been doing anything that's worth a blog post. I couldn't find a satisfying explanation as to why the coin flip sequence from a previous post corresponds to the Catalan number sequence, but I still plan to make that. After the wave equation, I'd like to make a blog post about how the heat equation is derived.

I've been recently trying out new topics. Steganography looks like a very fun one. I can certainly understand hiding an image within the 4 least-significant bits of each pixel, and I can sort of understand how hiding them in the DCT of a jpeg image works, but anything that's remotely more advanced looks like dark magic.

Similarly, I'd love to learn more about information theory and error correction. I can understand the simple version of parity bits and Reed-Solomon, but anything more advanced like elliptic curves is beyond me. Perhaps I should look for a good book.
