007 - Goatmire, Old Android Phones, and How To Keep a Secret

A tribute to Margaret Hamilton’s fault-tolerant software opens a broad roundup of BEAM news: changes to Gleam compilation, Elixir type-system research, Sobelow and other library updates, faster Hologram compilation, Android devices running Nerves, and easier access to Hex-built images. The rest covers Goatmire recaps, Bluesky’s ATProto, doc tests and regression testing, community events, secure handling of local and production credentials, and AI-assisted vulnerability scanning.
