Soft Delete in Django Without Making a Mess https://t.co/96BqVSlZEZ

I've recently started hiding the bulk of my AI-generated GitHub PR descriptions behind a collapsed <details><summary> HTML tag (thankfully supported by GitHub Markdown) and I think it's a useful pattern for making PR slop a little bit less exhausting https://t.co/JlFdAJovFt

[tobi lutke @tobi]

A huge amount of the Anti-AI code sentiment massively overestimates the quality of human code outside of a very small set of open source and high quality company codebases. Human Slop is everywhere and can trivially be improved on by any opus level model.

The most difficult part of Software Engineering was never writing the code.

It was decision-making.

[Armin Ronacher ⇌ @mitsuhiko]

I'm convinced that at this point, you could have an Opus 5.5 agent re-implement all of CPython probably within two weeks without any human input, against just the tests, and probably with full compatibility with including ABI, no GIL, a jit and probably beat it on all measurable metrics. It's completely crazy.

By the way, in case anyone was still wondering whether they are completely useless, Binance holds SOC 2 Type 2, ISO 27001, and several other certifications.

Incredibly bizarre thing happening to me: I've gotten really lazy in my prompting because the models are so robust to typos, word misuse, omitting words, etc.

But now I keep catching myself typing out messages the same way in Slack?

a lot of old software was protected by “exploiting this would be an unreasonable amount of work”

we have invented a machine that does unreasonable amounts of work

anyway how’s the patch backlog

Python 3.15 adds lazy imports with the new lazy keyword! 🐍

Instead of loading a module when your script starts, Python waits until you actually use it.

Here's a quick example:

lazy import json
lazy from pathlib import Path

Good use cases:

- CLI tools where most commands only need a few modules
- Big libraries like pandas or numpy that you only use in one code path
- Apps where startup time matters

The result is faster startup times with almost no code changes.

Will you use it? 🚀

Python 3.15 adds frozendict as a built-in type! 🐍

It works like a dict, but it's immutable. Once you create it, you can't change it. That also makes it hashable, so you can use it as a dict key or put it in a set.

Great for config data you don't want changed by accident.

Will you use it?

Here's a quick example:

[Mike Driscoll @driscollis]

Python 3.15 is officially out! 🐍🚀 Here are some of the new features I'm most excited to try:

1. Lazy imports with the new lazy keyword for faster startup times
2. frozendict is now a built-in type
3. A new sentinel built-in type
4. Unpacking in comprehensions
5. UTF-8 is now the default encoding
6. Tachyon, a new sampling profiler in the profiling package
7. A faster experimental JIT compiler
8. Better error messages and more color in the CLI

Which one will you use first?
