Brian #1: Open Source Pledge Learned about this because of this post Why Django supports the Open Source PledgeSteps Pay Open Source maintainers. Min to participate is 2k/year/dev at your companySelf-report annually Publish a blog post outlining your paymentsArmin’s post about launching Open Source Pledge and mixing money with open source Michael #2: Jeff Triplet's DjangoTV A nice aggregation of lots of Django conference talksFilter by conferenceGood search as well 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 #4: livereload Example from talkpython.fm: asset_bundler_watcher.pyThe docs are sparse, so see the gist above Extras Brian: Personal Blogs are no longer personal when AI gets too involved - KJayMillerMind Your Image Metadata - Stefanie Molin Michael: 14% of our listeners are in Germany, thanks Germany! Prost!Hetzner comes to the US Joke: A programmer’s partner asks them: “Would you go get a loaf of bread from the store? And if they have eggs, get a dozen.” A while later, the programmer returns with 12 loaves of bread and says “They had eggs.” From https://savvyprogrammer.io/software-jokes/

Michael #1: Briefer: Dashboards and notebooks in a single place Notebooks and dashboards with Python, SQL, scheduling, native visualizations, code generation, and more.In Briefer, you can: Create notebooks and dashboards using Markdown, Python, SQL, and native visualizations. Build interactive data apps using inputs, dropdowns, and date pickers. Generate code and queries using an AI that understands your database schema and your notebook's context. Schedule notebooks and dashboards to run and update periodically. Create and test ad-hoc pipelines using writebacks.Briefer vs. Traditional BI Tools: Briefer is better than traditional BI tools because it's faster and more flexible, thanks to Python.Briefer vs. Traditional Notebooks: In Briefer, you can run SQL queries against connected data sources directly in your notebook. Then, Briefer will automatically turn your query into a data frame and store it in a variable that you can use in your Python blocks. Brian #2: Introduction to programming with Python Jose Blanca “Python intro aimed at students with no prior programming experience.”“Relies mainly on examples and exercises.”“Does not try to cover every detail of the Python language, but just what a beginner might need to start the journey.”Tech: “… built with the quarto publishing system complemented by the quarto live extension that allows Python to run in the web browser by using pyodide.”Runs on anything, since it doesn’t require a local install of PythonRunning 3.12.1, looks like. Although that’s a bit hidden. Seems like it should be more visible. Michael #3: setup-uv Set up your GitHub Actions workflow with a specific version of uvInstall a version of uv and add it to PATHCache the installed version of uv to speed up consecutive runs on self-hosted runnersRegister problem matchers for error output(Optional) Persist the uv's cache in the GitHub Actions Cache(Optional) Verify the checksum of the downloaded uv executable Brian #4: HTML for people Teaching HTML in a rather fun way.Includes basic CSS Extras Michael: A new article: We Must Replace uWSGI With Something ElseDjango unique email login Joke: So much O’Really

Since the checksum stored on PyPI is immutable and required, it is not possible to spoof an external wheel file, even if the owning organization lost control of their hosting domain.Externally hosted wheels MUST be served over HTTPS.In order to serve externally hosted wheels, organizations MUST be approved by the PyPI admins. Brian #3: pytest-freethreaded PyCon JP 2024 Team: This extension was created at PyCon JP sprints with Anthony Shaw and 7 other folks listed in credits.“A pytest plugin for helping verify that your tests and libraries are thread-safe with the Python 3.13 experimental freethreaded mode.”Testing your project for compatibility with freethreaded Python. Testing in single thread doesn’t test that.Neither does testing with pytest-xdist, because it uses multiprocessing to parallelize tests.So, Ant and others “made this plugin to help you run your tests in a thread-pool with the GIL disabled, to help you identify if your tests are thread-safe.”“And the first library we tested it on (which was marked as compatible) caused a segmentation fault in CPython! So you should give this a go if you're a package maintainer.” Michael #4: pytest-edit A simple Pytest plugin for opening editor on the failed tests.Type pytest --edit to open the failing test code Be sure to set your favorite editor in the ENV variables Extras Michael: New way to explore Talk Python courses via topics This has been in our mobile apps since their rewrite but finally comes to the webLet's go easy on PyPI, OK? essayHynek’s video: uv IS the Future of Python Packaging djade-pre-commitPolyfill.io, BootCDN, Bootcss, Staticfile attack traced to 1 operatorPurgeCSS CLI Python 3.12.7 releasedIncremental GC and pushing back the 3.13.0 releaseuv making the roundsLLM fatigue, is it real?Take the Python Developers Survey 2024 Joke: Funny 404 pages We have something at least interesting at pythonbytes.fm
