This week we're joined by Bobby Grayson, a longtime Elixir developer and the creator of Deciduous, a decision graph that gives LLMs a living memory.Deciduous stores goals, options, and outcomes in a SQLite-backed graph that agents like Claude Code can query as they work, so they remember why decisions were made instead of repeating past mistakes.We talk about how it slots invisibly into an agent workflow, how teams share decision graphs, the surprising authors using it to organize their books, and where coding is headed in the next five years.

This week we're joined by Scott Lanoue, the creator of CoMail, a cooperative email service built on the AT Protocol.Getting a self-hosted mail server to actually land in the inbox is a months-long slog of warming IPs and building domain reputation, so CoMail pools that reputation across everyone sending through a shared relay.

We talk about how atproto identity lets CoMail vend out trust instead of spam scores, what it means to store your mail in your own PDS with spaces, and why a co-op might be a better shape than a startup for a protocol with no moats.

This week we're joined by Jacob Miller, founder of DiffUI, an AI-driven UI design tool. DiffUi uses diffusion models to generate UI designs, and then uses a large language model to convert the designs to code. Jacob is a design systems expert and has a lot of experience with design systems, and that's baked right into the product.
