Brian #1: Starlette 1.0.0 As a reminder, Starlette is the foundation for FastAPIStarlette 1.0 is here! - fun blog post from Marcello Trylesinski“The changes in 1.0 were limited to removing old deprecated code that had been on the way out for years, along with a few bug fixes. From now on we'll follow SemVer strictly.”Fun comment in the “What’s next?” section: “Oh, and Sebastián, Starlette is now out of your way to release FastAPI 1.0. 😉”Related: Experimenting with Starlette 1.0 with Claude skills Simon Willisonexample of the new lifespan mechanism, very pytest fixture-like @contextlib.asynccontextmanager async def lifespan(app): async with some_async_resource(): print("Run at startup!") yield print("Run on shutdown!") app = Starlette( routes=routes, lifespan=lifespan ) Michael #2: Astral to join OpenAI via John Hagen, thanksAstral has agreed to join OpenAI as part of the Codex teamCongrats Charlie and teamSeems like **Ruff** and uv play an important roll.Perhaps ty holds the most value to directly boost Codex (understanding codebases for the AI)All that said, these were open source so there is way more to the motivations than just using the tools.After joining the Codex team, we'll continue building our open source tools.Simon Willison has thoughtsdiscuss.python.org also has thoughtsThe Ars Technica article has interesting comments tooIt’s probably the death pyx Simon points out “pyx is notably absent from both the Astral and OpenAI announcement posts.” Brian #3: uv audit Submitted by Owen LemontPieces of uv audit have been trickling in. uv 0.10.12 exposes it to the cli helpHere’s the roadmap for uv auditI tried it out on a package and found a security issue with a dependency not of the project, but of the testing dependenciesbut only if using Python < 3.10, even though I’m using 3.14Kinda coolLooks like it generates a uv.lock file, which includes dependencies for all project supported versions of Python and systems, which is a very thorough way to check for vulnerabilities.But also, maybe some pointers on how to fix the problem would be good. No --fix yet. Michael #4: Fire and forget (or never) with Python’s asyncio Python’s asyncio.create_task() can silently garbage collect your fire-and-forget tasks starting in Python 3.12Formerly fine async code can now stop working, so heads upThe fix? Use a set to upgrade to a strong ref and a callback to remove itIs there a chance of task-based memory leaks? Yeah, maybe. Extras Brian: Nobody Gets Promoted for Simplicity - interesting read and unfortunate truth in too many places.pytest-check - All built-in check helper functions in this list also accept an optional xfail reason. example: check.equal(actual, expected, xfail="known issue #123")Allows some checks to still cause a failure to happen because you no longer have to mark the whole test as xfail Michael:TurboAPI - FastAPI + Pydantic compatible framework in Zig (see follow up)Pyramid 2.1 is out (yes really! :) first release in 3 years)Vivaldi 7.9 adds minimalist hide mode.Migrated pythonbytes.fm and talkpython.fm to Raw+DC design patternRobyn + Chameleon package Joke: We now have translation services
