De Bruijn Sequences

De Bruijn sequences make up a niche topic at an intersection of graph theory and combinatorics. We will discuss some of the properties of these sequences, and their surprising applications.

RSA Encryption

You use the RSA encryption scheme every day. It's simple enough to understand, but quite powerful. In this post, we discuss the basics of ciphersystems, public key encryption, and why RSA works so well.

Huffman Compression

Data compression is a process of modifying the representation of some information so that it can be stored using less data. We discuss how information is quantified (entropy), and a simple, speedy, and greedy compression algorithm (the Huffman Coding).
