1 hour 13 minutes

News includes the public launch of Phoenix.new - Chris McCord's revolutionary AI-powered Phoenix development service with full browser IDE and remote runtime capabilities, Ecto v3.13 release featuring the new transact/1 function and built-in JSON support, Nx v0.10 with improved documentation and NumPy comparisons, Phoenix 1.8 getting official security documentation covering OWASP Top 10 vulnerabilities, Zach Daniel's new "evals" package for testing AI language model performance, and ElixirConf US speaker announcements with keynotes from José Valim and Chris McCord. Saša Jurić shares his comprehensive thoughts on Elixir project organization and structure, Sentry's Elixir SDK v11.x adding OpenTelemetry-based tracing support, and more! Then we dive deep with Chris McCord himself for an exclusive interview about his newly launched phoenix.new service, exploring how AI-powered code generation is bringing Phoenix applications to people from outside the community. We dig into the technology behind the remote runtime and what it means for the future of rapid prototyping in Elixir.
