What's a UUID, and what do you use that for? www.bitecode.dev/p/whats-a-uu... Since UUID 7 is landing in Python and PostGres, and given there is a little debate about that right now, let's open up the fun to more people.

I got liked by "A shameless smut connoisseur devoted to lesbian milky fantasies, luxurious submission". I can see how a Python fits in there, mind you, but still. Spam is getting into substack, which means it is getting more and more important for BiteCode to get its own platform.

"How I, a non-developer, read the tutorial you, a developer, wrote for me, a beginner" anniemueller.com/posts/how-i-... This is so real.

It's official - `django.tasks` exists! Coming soon to @djangoproject.com 6.0. 585 days later, the first step (of many) in Django's background tasks journey is finally complete! 🥳 theorangeone.net/posts/django...

I have spent the last few days implementing a Diif viewer for Toad. It supports unified and split view diffs, with line-level highlights. Rather pleased with the results! #Python #Textual

It seems like using bwrap (from the bubblewrap linux isolation utility) with claude --dangerously-skip-permissions can give the best of both worlds. Anybody is doing this?

Clair obscur, Silk Song and Hades 2 all in 2025. The GOTY vote is going to be madness this year.

Whenever I want to post a "rate my setup", I realize that they are always on both the "awesome" and "horrible" spectrum at the same time:

Hello Python developers! 🐍✨ The 2025 Python Type System and Tooling Survey is live! No typing experience needed – just your dev perspective.💡💻 Take 10 minutes to share your thoughts and help improve Python typing for all. 👉 Survey: jb.gg/d7dqty #Python #DeveloperSurvey

$3,000 to each author for each book, largest total copyright infringement recovery in history. This is massive win and a huge blow to AI companies—and this out of the case that otherwise allowed training as fair use. Other judges are already more sympathetic to authors. deadline.com/2025/09/anth...

🖤 Amazing! Btw it’s still called tachyon but people didn’t want to have the double import with the alias 😅

While Nintendo announced $90 games, Silk Song, one the most anticipated games this decade, just released for $20.

I used to never use AI for style reasons when writing, it has no taste. It's useful for typos and proof reading in general, but not for making something personal. However, today, for the first time, it has suggested in an email a better tone that the one I chose, in a professional setting.

Made this a little more robust. There are some interesting subtleties here. `setTimeout` doesn't accept a delay of more than 2147483647 milliseconds (24 days 20 hours 31 minutes 23.647 seconds), and leap years add to the fun too And it's a hassle to unit test gist.github.com/qntm/7905d07...

I have to tell myself that it's fine if my Python code examples use f-strings. Python 3.6 is not a "too new" version of Python.

Just noticed that sadly, the proposal to add a “default” keyword to attrgetter(), itemgetter() and getitem() has been rejected: peps.python.org/pep-0769/ It’s part of the list of things that makes manipulating containers annoying. Like not having default on list.get(), or missing ? and ??.

Very useful in general, not just in tests, but because sometimes, you have dependencies that are just coded with side effect and you need to capture what they do.

Quite a terrible title for a great articles giving you an overview of modern facilities in CSS: lyra.horse/blog/2025/08... I’m so far removed from it since tailwind that I missed that nesting and variables were usable now.

I posted about Toad, my agentic coding interface for the terminal. Going to make this a regular-ish thing until the app is solid enough to share. willmcgugan.github.io/toad-report-1/

Rust is really eating the world of package managers. After Python and JS, now Ruby: andre.arko.net/2025/08/25/r...

The Python documentary by @cultrepo.bsky.social is going to be debuting live on YouTube on Thursday the 28th at 7pm CET/10am PT! www.youtube.com/@cultrepo I'll share a link the day before to the doc that will have a countdown to the debut. I'm planning to be in the live chat during the debut.

If there was one place I wasn't expecting rebellion from, it was imgur. Well, I'm delightfully surprised by the frontpage right now:

Accessing `obj.x` in Python might look trivial — but under the hood lies a surprisingly intricate chain of logic. I wrote an annotated walkthrough of the CPython source code that makes it all happen: antocuni.eu/2025/08/25/i...

Fantastic post by @bitecode.dev arguing that AI has not fundamentally changed the fact that young developers have to learn some way, that "some way" is different with AI, but we've all been there, so let's acknowledge it, embrace it, speak our wisdom with humility, and keep hacking.

Why the "declare AI help in your PR" is useless, courtesy of 3000 years ago logic: - If you can't tell without the disclaimer, it's useless: people will not tell. - If you can tell, it's useless: you can tell. Just evaluate quality, not process.

PSA: attrs 25.4 will change how it handles class-level kw_only to conform with dataclass transform rules (IOW act like type-checkers ex Mypy expect). We found 0 cases in the wild where this would break anything so it's on for NG APIs. Now is the time to stop us. 🤓

TIL you can run an eval suite against OpenAI's gpt-oss-20b open weights model running in LM Studio with the following uv one-liner. Here's my full TIL: til.simonwillison.net/llms/gpt-oss...

In theory, if we'd invest 30% of the productivity gains from AI to improve testing, doc and the team culture, we would be golden. In practice, something tells me it's just going to be swallowed in by higher expectations. I do hope I will be proved wrong thought.

Vibes coding is fine. And yes, the kids suck, but so did we. Let's appreciate we got new players entering the game, and focus on what's really important: improving safety nets. www.bitecode.dev/p/the-kids-a...

The Steering Council accepted @pablogsal.com's PEP 799! New `profiling` module: * `tracing`: deterministic function-call tracing (moved from cProfile) * `sampling`: new statistical sampling profiler Old `profile` deprecated discuss.python.org/t/pep-799-a-... #Python #profiling #PEP799 #Python315

Key point: half of the community is made of inexperienced programmers, reflecting how massively new devs keep choosing Python as a starting point every day. This is very important to understand if you write documentation, create tooling or need to target pythonistas in any way.

This is really fascinating Wikipedia's list of linguistic and stylist "tells" of AI writing, the better to help editors recognize it en.wikipedia.org/wiki/Wikiped...

Websites are starting to serve AI translated user content. Youtube gives you awful artificial dubs, reddit returns cringe versions of english content in whatever your local is. And they don't tell you they do it. You just know something is really wrong, and then, after a while, it clicks.

I forward receipts to my bank regularly, and wanted a button on thunderbird to do that. Existing addons (like oneclick forward) are not exactly what I want, so I though, let's ask claude. It took an hour of back and forth, but I now have totally custom running addon that works. Love it.

An example use case for Python 3.14's `functools.placeholder`: from functools import partial, Placeholder import string strip_punctuation = partial( str.translate, Placeholder, str.maketrans("", "", string.punctuation), ) print(strip_punctuation("Hello, world!")) # Hello world

Today, we're announcing our first hosted infrastructure product: pyx, a Python-native package registry. We think of pyx as an optimized backend for uv: it’s a package registry, but it also solves problems that go beyond the scope of a traditional "package registry".
