SF October 14th: A Birds of a Feather Session on Agentic Engineering . I'm hosting an evening event with Jesse Vincent in San Francisco on Wednesday 14th October for people who are building weird and interesting things with and on top of coding agents.
Think of it as an agentic show-and-tell:
Compare notes with other builders and experimenters on things you’re trying, what you're learning, and what you haven’t figured out yet. We’re especially interested in work you haven’t discussed publicly, odd experiments, or unfinished projects that don’t have an obvious market. Expect one flowing conversation with an informal show-and-tell. Sharing something you’re working on is encouraged but no presentation is required.
This isn't about product pitches, it's about much earlier explorations than that. This agentic AI stuff is weird! Let's celebrate and lean into that weirdness.
