PSA if you're in the market for a Python web framework, you should check out @AirWebFramework. It brings together a lot of what's good in other products (FastAPI, Pydantic, support for Jinja, HTML in Python, HTMX) and leaves out much of the less fun stuff.
Warning off users from a public project that is in Alpha. 😅
Tip: You don't need python-dotenv, use "uv run" with --env-file, and your env vars from .env get loaded. For example, if you've got a @FastAPI project you can run it locally with env vars like: uv run --env-file .env fastapi dev
Stuff like Anthropic's $1.5b settlement is why I'm so hesitant to write another tech book. Months of my labor is worth significantly more than the $3k Anthropic _MIGHT_ pay me. Also, the other tech companies do the same. @simonw writes about the suit: simonwillison.net/2025/Sep/6/ant…
Software engineering is 90% database and 10% frontend.
🤖 OpenAI rewrote Codex CLI in Rust 🦀 and it's actually good now! Lightweight, fast, works with ChatGPT subs. We tested it with @AirWebFramework. It learned the docs, planned the build, wrote the code, and fixed its own bugs. Open, flexible, legit! ⚡ elite-ai-assisted-coding.dev/p/codex-cli-to…
I love learning new things. Today I learned a pytest-friendly way to set environment variables easily and consistently. daniel.feldroy.com/posts/til-2025…
Imagine building something so useful that millions depend on it monthly The creators of Cookiecutter (5M+ dls/mo) and Two Scoops of Django back our course b/c that's what we teach Real impact. Real endorsement from real builders @pydanny @audreyfeldroy Discount Code: FELDROY
What's fun about the goofy, hypercompetitive Manila Python meetup games is they are just so good natured. Met a lot of good people already.

Sometimes it's good to code by yourself, other times it's good to pair. Today was a good pairing day. 🙂 Doubly so as it was with @audreyfeldroy ❤️
Our company name "Feldroy" is a contraction of @pydanny and @audreyfeldroy's last name "Roy Greenfeld" It's not their actual surname. But it does sound suspiciously like it could be

So true. Quite a few of the stingiest developers I know are shelling out $$$ to Cursor and Anthropic.

Anyone else notice that new contributors on an open source project asking for a ticket to be assigned to them will then camp on the ticket?
Once again it is being politely pointed out that when I say I'm "vibe-coding" I'm actually using LLMs to validate my approach. 😅
