Michael #1: uv under discussion on Mastodon It’s interesting that uv is slightly controversialRussell:As enthusiastic as I am about the direction uv is going, I haven't adopted them anywhere - because I want very much to understand Astral’s intended business model before I hook my wagon to their tools.Hynek:As much as I hate VC, [...] FOSS projects flame out all the time too. … To me uv looks like a genius sting to trick VCs into paying to fix packaging. We’ll be better off either way.Glyph:Rust is more expensive and difficult to maintain, not to mention "non-native" to the average customer here. … it can burn out all the other projects in the ecosystem simultaneously, creating a risk of monocultureHynek on Rust:I don’t think y’all quite grok what uv makes so special due to your seniority. The speed is really cool, but the reason Rust is elemental is that it’s one compiled blob that can be used to bootstrap and maintain a Python development.Christopher Neugebauer:Just dropping in here to say that corporate capture of the Python ecosystem is the #1 keeps-me-up-at-night subject in my community work, so I watch Astral with interest, even if I'm not yet too worried.Armin RonacherWhat uv is doing, even in the worst possible future this is a very forkable and maintainable thing.Finally, see the comment at the end by Charlie Marsh Brian #2: erdantic: Entity Relationship Diagrams “erdantic is a simple tool for drawing entity relationship diagrams (ERDs) for Python data model classes. Diagrams are rendered using the venerable Graphviz library.”Supported data modeling frameworks are: Pydantic V2Pydantic V1 legacyattrsdataclasses Michael #3: Extra, Extra, Extra Added Python Bytes Search as a custom search engine.Along came passkeys. A cool idea that quickly turned evil.Follow up from post and my conversation last week: vaultwarden (via Pablo)uv publishTrying the tabs on bottom lifestyle inspired by ArcAdding Python Bytes (and Talk Python) as custom search engines.PyCon 2025 dates: From 14 May through 22 May, 2025 Brian #4: Django Extra, Extra, Extra Django Project Ideas Evgenia VerbinaProject ideas with list of tech stack stuff you’ll learn and/or work on with the projectEx: Recipe organizer tech stack: Django templates, Django ORM, Optional JavaScript“Familiarize yourself with Django’s ORM (object-relational mapper) and database support by building an app to keep track of your favorite recipes. Add a web-based frontend with options to filter recipes by category, ingredients, and user ratings so you can easily browse for inspiration.”DjangoTV Jeff TriplettDjango conference videos and tutorials.Django Commons Heard about from Lacey Henschel“Django Commons is an organization dedicated to supporting the community's efforts to maintain packages. It seeks to improve the maintenance experience for all contributors; reducing the barrier to entry for new contributors and reducing overhead for existing maintainers.”Django 5 has simplified templates for better form field renderingBut if you want a completely different take on forms, maybe try iommi forms They wrote about it on Why we wrote a new form library for DjangoDjade: a Django template formatter Adam JohnsonLike black or ruff, but for Django templates.

Brian #1: Architecture Decision Records (ADRs) Suggested by Christian GesellDocumenting Architecture Decisions Mychael NygardOriginal article from 2011Why you should be using architecture decision records to document your project Red HatIncludes a quick overview and links to some templatesNotes so far Writing this out helps me solidify my thinking about a problem.I’m doing this both before starting, and while implementing a first draftGitHub and GitLab render markdown so well that generating a docs site is unnecessary, just throwing these files in something like docs/adr is enough.The lightweight process is enough but not too much.I’ve already filled out None for lots of sections, like “options considered”I’m still playing with what level of decision should have an ADR.My template that I’ve been using so far Saved in 000-adr-template.mdFor easy copy/paste/modify for new records.File name is something like 001-some-change.md Michael #2: narwhals: extremely lightweight compatibility layer between dataframes Recently had Marco on Talk Python to discussPrimarily for library creators who want to support interacting with multiple data frame libraries (.e.g. Pandas & Polars)Just use a subset of the Polars API Brian #3: Microsoft wants Three Mile Island to fuel its AI power needs “Microsoft just signed a deal to revive the shuttered Three Mile Island nuclear power plant. If approved by regulators, the software maker would have exclusive rights to 100 percent of the output for its AI data center needs.”Also ran on CNN and other sources: Three Mile Island is reopening and selling its power to MicrosoftThree Mile Island was the site of the worst nuclear disaster in the US, when one of two reactors experienced a partial meltdown, in 1979. It was still operating up until 2019, and now expected to re-open in 2028Will be renamed “Crane Clean Energy Center”related The Department of Energy Wants You to Know Your Conservation Efforts Are Making a Difference “By switching all the lightbulbs in your house to LED, you saved enough energy for a self-driving car to make an unprotected lefthand turn across three lanes of traffic.”“We know you adopted energy-saving practices to help conserve our planet’s resources and bring down our collective carbon footprint, but what you ultimately accomplished is just as important: helping AI do something menial and stupid.” Michael #4: zsh-in-docker Install Zsh, Oh My Zsh and plugins inside a Docker container with one line!Yes docker containers should be light, but also, think of how painful it can be when you run into trouble.With Oh My ZSH, you get a nice experience when you have to result to docker exec -it CONTAINER zshJust enter a single command in your docker file: RUN sh -c "$(wget -O- https://github.com/deluan/zsh-in-docker/releases/download/v1.2.0/zsh-in-docker.sh)" -- \ -t robbyrussell Extras Michael: self-hosting mkennedy.codesLoren's journey to developerIt’s time to stop using Python 3.8Sonoma → Sequoia → Sonoma (yikes!)Passkeys, maybe they will work out if we don’t let them become lock-in (bitwarden’s support) Joke: How to Monetize a Blog Don’t forget to click on the bottom link: Credits / how this was made

Michael #1: “We must replace uwsgi by something else” uWSGI is now in maintenance mode: https://uwsgi-docs.readthedocs.io/en/latest/ The project is in maintenance mode (only bugfixes and updates for new languages apis). Do not expect quick answers on github issues and/or pull requests (sorry for that) A big thanks to all of the users and contributors since 2009.Reasonable options look like: granianuvicornhypercorngunicorn (potentially with uvicorn workers for async) Brian #2: Let’s build and optimize a Rust extension for Python Itamar Turner-TrauringExample: algorithm for approximating the number of unique values in a listComparison to non-approximation non-approx is faster but uses way more memoryRust version Use Maturin and PyO3Pull in Rust dependencies (rand for random numbers)Optimization link-time optimizationfaster randomstore hashes onlyFuture optimizations change algorithm maybepass numpy array instead of Python list (I’d like to see that spedup) Michael #3: Fake recruiter coding tests target devs with malicious Python packages via python weeklyGitHub projects that have been linked to previous, targeted attacks in which developers are lured using fake job interviews.Attackers posing as employees of major financial services firms.This previously happened via other means such as NPMThis analysis revealed that the direct parent of the detected, malicious files is a PythonPYC file, meaning that once again the team encountered malware hidden in a compiled Python file.“The README files tell would-be candidates to make sure the project is running successfully on their system before making modifications.”What can you do (according to Michael)? Try out new packages in a docker containerWork on code and projects using a VM which has snapshotting (to roll back completely after you’re done)Fire up a Windows desktop in the cloud for the project then destroy it Brian #4: Monthly PSF Board Office Hours “The Office Hours will be sessions where you can share with us how we can help your community, express your perspectives, and provide feedback for the PSF.”“Unless we have a dedicated topic for a session, you are not limited to talking with us about the above topics, although the discussions should be focused on Python, the PSF, and our community.
