Michael #1: Django Modern Rest Modern REST framework for Django with types and async support Supports Pydantic, Attrs, and msgspec Has ai coding support with llms.txt See an example at the “showcase” section Brian #2: Already playing with Python 3.15 3.15.0a8, 2.14.4 and 3.13.13 are out Hugo von Kemenade beta comes in May, CRs in Sept, and Final planned for October But still, there’s awesome stuff here already, here’s what I’m looking forward to: PEP 810: Explicit lazy imports PEP 814: frozendict built-in type PEP 798: Unpacking in comprehensions with * and ** PEP 686: Python now uses UTF-8 as the default encoding Michael #3: Cutting Python Web App Memory Over 31% I cut 3.2 GB of memory usage from our Python web apps using five techniques: async workers import isolation the Raw+DC database pattern local imports for heavy libraries disk-based caching See the full article for details. Brian #4: tryke - A Rust-based Ptyhon test runner with a Jest-style API Justin Chapman Watch mode, Native async support, Fast test discovery, In-source testing, Support for doctests, Client/server mode for fast editor integrations, Pretty, per-assertion diagnostics, Filtering and marks, Changed mode (like pytest-picked), Concurrent tests, Soft assertions, JSON, JUnit, Dot, and LLM reporters Honestly haven’t tried it yet, but you know, I’m kinda a fan of thinking outside the box with testing strategies so I welcome new ideas. Extras Brian: Why are’t we uv yet? Interesting take on the “agents prefer pip” Problem with analysis. Many projects are libraries and don’t publish uv.lock file Even with uv, it still often seen as a developer preference for non-libarries. You can sitll use uv with requirements.txt PyCon US 2026 talks schedule is up Interesting that there’s an AI track now. I won’t be attending, but I might have a bot watch the videos and summarize for me. :) What has technology done to us? Justin Jackson Lean TDD new cover Also, 0.6.1 is so ready for me to start f-ing reading the audio book and get on with this shipping the actual f-ing book and yes I realize I seem like I’m old because I use “f-ing” while typing. Michael: Python 3.14.4 is out Beanie 2.1 release Joke: HumanDB - Blazingly slow. Emotionally consistent.
