**The Doctor** is a security practitioner and systems engineer working somewhere on the west coast. When not reading hex dumps, writing agents and bots, or spending time with his family, he spends too much time and money restoring and tinkering with classic 8-bit computers. He occasionally blogs about what he's working on (and sometimes how it nearly blew up in his face). Many of his programming projects recently have been to help people assess the risk of COVID-19 and determine what safety measures to take. A nontrivial fraction of his exocortex is interfaced with the Fediverse.
