In this episode we chat with Sune Debel about his Stateless library which brings Effect Oriented Programming to Python.https://github.com/suned/statelessPrior attempt at at Scala ZIO port to Python:https://github.com/suned/pfun

We dive into the new Aver programming language with its creator, Szymon Teżewski: The AI-native language where code explains itself.Aver is a language where every function carries its intent, side effects are visible in the type system, and tests are executable specs next to the code. The optimization target is the reviewer, not the generator.Resources:- Aver: https://averlang.dev/- Agent Languages: https://agentlanguages.dev/Discuss this episode: ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠discord.gg/XVKD2uPKyF

At Western State Colorado University in Gunnison on Sept 11, 2025, Bruce Eckel, Bill Venners and Dianne Marsh each give their own 10-minute perspectives on finding fulfillment in the field, especially considering the impact of AI and other recent changes in computing. The remainder of the session answers questions from the student audience.Discuss this episode: ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠discord.gg/XVKD2uPKyF

Infrastructure as Code (IaC) is "code" but without most of the benefits of being code. Sam Goodwin is reinventing IaC with Alchemy and an upcoming Alchemy Effect project which aims to manage infrastructure dependencies & provisioning in the same way we manage requirements in Effect Oriented Programming.Discuss this episode: ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠discord.gg/XVKD2uPKyF⁠⁠

Excitement around Python type checking continues to grow and the tools continue to evolve. We chat with Aaron Pollack and Steven Troxler about ⁠Pyrefly - a Rust-based Python type checker and IDE extension. We also touch on the adoption and sentiment around types in Python's ecosystem.Resources:Pyrefly DiscordPackage Type Coverage ReportPackages being tracked for moving types from typeshed to the source projectTyping Survey SlidesBlog post with survey analysisPython typing community forumMCP PyreflyDiscuss this episode: ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠discord.gg/XVKD2uPKyF⁠⁠

Carl Meyer works on the ty Python type checker, built in Rust by Astral the creators of Ruff and uv.
