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 …”Alternatives classdataclassdictionaryTypedDictSimpleNamespace“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 Extras Brian: Changing the Python Test community Was started to answer questions for Test & Code listeners years ago. Primarily pytest questionsUsed to be Slack. Then moved to Podia forum. Now I’m trying to work out a Discord solution that is both sustainable and usable.

Michael #1: terminal-tree An experimental filesystem navigator for the terminal, built with TextualTested in macOS only at this point. Chances are very high it works on Linux. Slightly lower chance (but non-zero) that it works on Windows. Can confirm it works on Linux Brian #2: posting: The API client that lives in your terminal Also uses TextualFrom Darren BurnsInteresting that the installation instructions recommends using uv: uv tool install --python 3.12 postingVery cool. Great docs. Beautiful. keyboard centric, but also usable with a mouse.“Fly through your API workflow with an approachable yet powerful keyboard-centric interface. Run it locally or over SSH on remote machines and containers.

Brian #1: GitHub action security: zizmor Article: Ned Batchelder zizmor: William Woodruff & others“a new tool to check your GitHub action workflows for security concerns.”Install with cargo or brew, then point it at workflow yml files.It reports security concerns. Michael #2: Python is now the top language on GitHub Thanks to Pat Decker for the heads up.A rapidly growing number of developers worldwide This 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.
