New blog post: I Am Not A Reverse Centaur blog.miguelgrinberg.com/post/i-am-no...

I don't know how to explain to the people who pop up when creatives complain about "AI" to say there are legit uses for it just how much they sound like someone saying "Well actually fire is used to make bread" when people are talking about an organized arson ring burning down their fucking houses

A Borges story about a guy who gets AI to summarize all the world’s information for him, and then summarize the summary, until the AI has the whole world summarized into a single word. He sits alone at his desk, staring at the word, repeating it endlessly, certain he is experiencing everything

The cons of generative AI for authors and artists are still there, even if you as a software developer don't experience them directly.

PyCon Ireland 2025 is next weekend and I will be speaking about Server Sent Events. I hope to see some of you there!

On this week's episode, @digiglean.bsky.social and I talk about loads of PEPs, more 3.14 news, and discuss what it means to have good engineering taste. With content from: @brianokken.bsky.social @miguelgrinberg.com @changs.co.uk @davepeck.org and others not on the 🦋

@nader.mx hi, I'll try to find out what's going on. The people who used your gifts are still members as far as I can see.

Python 3.14 Is Here. How Fast Is It? blog.miguelgrinberg.com/post/python-...

Python tip: the str.split() method does something completely different when called without arguments vs. passing a separator character. I spent more time than I'm willing to admit today debugging a string parser, and this was the main issue!

Why Generative AI Coding Tools and Agents Do Not Work For Me blog.miguelgrinberg.com/post/why-gen...

I kinda hated writing this but I needed to do it. Maybe now, finally, I can stop writing it in little fragments here and there, and just let it go and do something else. https://blog.glyph.im/2025/06/i-think-im-done-thinking-about-genai-for-now.html

A Year In Review: Flask in 2024 blog.miguelgrinberg.com/post/a-year-...

@miguelgrinberg.bsky.social I have tried close to 10 times to sit down and truly get flask and databases in general, until your flask tutorial made it all click. Literally everything down to the source files. Did it take a while to digest? Yes. But will I know it forever now? Absolutely. Thanks!

It's great that I have a long holiday break from work, as that allows me to give my full attention to my open source projects. In the last few days I have released new versions of my Socket.IO packages for Python, with several improvements and bug fixes, so be sure to upgrade if you use them!
