Brian #1: pre-commit: install with uv Adam Johnsonuv tool works great at keeping tools you use on lots of projects up to date quickly, why not use it for pre-commit.The extension of pre-commit-uv will use uv to create virtual environments and install packages fore pre-commit. This speeds up initial pre-commit cache creation. However, Adam is recommending this flavor of using pre-commit because it’s just plain easier to install pre-commit and dependencies than the official pre-commit install guide.Win-win.Side note: No Adam, I’m not going to pronounce uv “uhv”, I’ll stick with “you vee”, even Astral tells me I’m wrong Michael #2: PEP 773: A Python Installation Manager for Windows (Accepted) via pycoders newsletterOne manager to rule them all – PyManager.PEP 773 replaces all existing Windows installers (.exe “traditional” bundle, per-version Windows Store apps, and the separate py.exe launcher) with a single MSIX app called Python Install Manager (nick-named PyManager).PyManager should be mainstream by CPython 3.15, and the traditional installer disappears no earlier than 3.16 (≈ mid-2027).Simple, predictable commands. python → launches “the best” runtime already present or auto-installs the latest CPython if none is found.py → same launcher as today plus management sub-commands:py install, py uninstall, py list, py exec, py help.Optional python3 and python3.x aliases can be enabled by adding one extra PATH entry. Michael #3: Changes for Textual Bittersweet news: the business experiment ends, but the code lives on.Textual began as a hobby project layered on top of Rich, but it has grown into a mature, “makes-the-terminal-do-the-impossible” TUI framework with an active community and standout documentation.Despite Textual’s technical success, the team couldn’t pinpoint a single pain-point big enough to sustain a business model, so the company will wind down in the coming weeks.The projects themselves aren’t going anywhere: they’re stable, battle-tested, and will continue under the stewardship of the original author and the broader community. Brian #4: The Best Programmers I Know Matthias Endler“I have met a lot of developers in my life. Lately, I asked myself: “What does it take to be one of the best? What do they all have in common?””The list Read the referenceKnow your tools really wellRead the error messageBreak down problemsDon’t be afraid to get your hands dirtyAlways help othersWriteNever stop learningStatus doesn’t matterBuild a reputationHave patienceNever blame the computerDon’t be afraid to say “I don’t know”Don’t guessKeep it simpleEach topic has a short discussion. So don’t just ready the bullet points, check out the article. Extras Brian: I had a great time in Munich last week. I a talk at a company event, met with tons of people, and had a great time. The best part was connecting with people from different divisions working on similar problems.I love the idea of internal conferences to get people to self organize by topic and meet people they wouldn’t otherwise, to share ideas.Also got started working on a second book on the plane trip back. Michael: Talk Python Clips (e.g. mullet)Embrace your cloud firewall (example).Python 3.14.0 beta 1 is hereCongrats to the new PSF Fellows.Cancelled faster CPythonhttps://bsky.app/profile/snarky.ca/post/3lp5w5j5tws2i Joke: How To Fix Your Computer
