Small, sharp tools and maps for keeping personal finances honest, seeing where the AI industry and its security actually stand, reconstructing a recent AI security incident, war-gaming a cloud architecture against real breach data, and keeping an eye on your Claude usage. There are a couple just for fun too: a reader’s guide to Jin Yong and a personality quiz for parties. Built and run by one person.
