This is essentially my notebook containing all of my notes during my CTF journey. The target audience is mainly CTF players, but there are also general computer science and mathematics topics in this project.
House of Note is a notebook. That is, it is not a textbook that teaches you everything in detail. Instead, it is more like a collection of cheatsheets. For most articles here, there will be a "Required Reading" section for external references and it is your job to read those articles first. I believe that it is the best way of learning: learn things from the entire Internet, not from a single place. After learning all the details from external resources, come back to House of Note and use the content here for a quick reference in the future.
