    Brian #2: PyPI now supports digital attestations

    Dustin Ingram“Attestations provide a verifiable link to an upstream source repository: By signing with the identity of the upstream source repository, such as in the case of an upload of a project built with GitHub Actions, PyPI's support for digital attestations defines a strong and verifiable association between a file on PyPI and the source repository, workflow, and even the commit hash that produced and uploaded the file. Additionally, publishing attestations to a transparency log helps mitigate against both compromise of PyPI and compromise of the projects themselves.”For maintainersIf using GH Actions and Trusted Publishingmake sure you use pypa/gh-action-pypi-publish, version v1.11.0 or newerthat’s itIf not“Support for automatic attestation generation and publication from other Trusted Publisher environments is planned.”“While not recommended, maintainers can also manually generate and publish attestations.”See also PyPI Introduces Digital Attestations to Strengthen Python Package Security by Sarah GoodingAre we PEP 740 yet?

    Brian #1: Thoughts on Django’s Core

    Carlton GibsonGreat discussion on Django and Core vs PluginsSustainability with limited peopleKeeping core smallThe release cycleeembrace plugins vs endorsing plugins.

    Michael #2: futurepool

    via Pat DeckerTakes the concept of multiprocessing Pool to the async/await world.

    Create a pool then delegate the work:

    async with FuturePool(2) as fp: result = await fp.map(async_pool_fn, range(10))

    I would LOVE to see something like this in a broader background asyncio worker pool concept.

    But that concept doesn’t exist in asyncio in Python and that’s a failing of the framework IMO.

    Brian #3: Don't return named tuples in new APIs

    Brett CannonFirst off, I’m grateful for any post that talks about APIs and the API is a module, class, or package API and not a Web/REST API. The term API existed long before the internet.“e.g., get_mouse_position() very likely has a two-item tuple of X and Y coordinates of the screen”“it actually makes your API more complex for both you and your users to use. For you, it doubles the data access API surface for your return type as you have to now support index-based and attribute-based data access forever (or until you choose to break your users and change your return type so it doesn't support both approaches)”“
 you probably don't want people doing with your return type, like slicing, iterating over all the items 
”AlternativesclassdataclassdictionaryTypedDictSimpleNamespace“My key point in all of this is to prefer readability and ergonomics over brevity in your code. That means avoiding named tuples except where you are expanding to tweaking an existing API where the named tuple improves over the plain tuple that's already being used.”

    Michael #4: Ziglang: Migrating from AWS to Self-Hosting

    The Rust Foundation for example, reports that they spent $404,400 on infrastructure costs in 2023.Zig lang has decided to use a single big cloud machine + mirrors

    Michael #2: Python is now the top language on GitHub

    Thanks to Pat Decker for the heads up.A rapidly growing number of developers worldwideThis suggests AI isn’t just helping more people learn to write code or build software faster—it’s also attracting and helping more people become developers. First-time open source contributors continue to show wide-scale interest in AI projects. But we aren’t seeing signs that AI has hurt open source with low-quality contributions.Python is now the most used language on GitHub as global open source activity continues to extend beyond traditional software development.The rise in Python usage correlates with large communities of people joining the open source community from across the STEM world rather than the traditional community of software developers.There’s a continued increase in first-time contributors to open source projects. 1.4 million new developers globally joined open source with a majority contributing to commercially backed and generative AI projects. Notably, we did not see a rise in rejected pull requests. This could indicate that quality remains high despite the influx of new contributors.

    Brian #3: PEP 735 – Dependency Groups in pyproject.toml

    Author: Stephen Rosen, Sponsor: Brett Cannon, PEP-Delegate: Paul MooreAccepted. Resolotion Oct 10, 2024“This PEP specifies a mechanism for storing package requirements in pyproject.toml files such that they are not included in any built distribution of the project.”Allow us to define named groups of dependencies that can be independent of the main project.

    ex:

    [dependency-groups]test = ["pytest", "coverage"]docs = ["sphinx", "sphinx-rtd-theme"]typing = ["mypy", "types-requests"]typing-test = [{include-group = "typing"}, {include-group = "test"}, "useful-types"]

    “might” work like this: pip install --dependency-groups=test,typing

    but tool venders are able to define how they use groups. Of course.Similar solutions multiple requirements.txt files: requirements_test.txt, requirements_docs.txt, etc.no standard naming convention, not standardized package extras: not gauranteed to be statically defined (TIL)additional to main dependencies, so not independent

    Michael #1: uv under discussion on Mastodon

    It’s interesting that uv is slightly controversial

    Russell:

    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 monoculture

    Hynek 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 Ronacher

    What uv is doing, even in the worst possible future this is a very forkable and maintainable thing.

    Brian #1: Architecture Decision Records (ADRs)

    Suggested by Christian GesellDocumenting Architecture DecisionsMychael NygardOriginal article from 2011Why you should be using architecture decision records to document your projectRed HatIncludes a quick overview and links to some templatesNotes so farWriting 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 farSaved 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”relatedThe 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

    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 versionUse Maturin and PyO3Pull in Rust dependencies (rand for random numbers)Optimizationlink-time optimizationfaster randomstore hashes onlyFuture optimizationschange 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
