Generating running routes with GPT-6 Astra and ChatGPT Work
Here's a neat thing I had ChatGPT Work with GPT-6 Astra (Max) do this morning:
I live at <my address>. Figure out 5K and 10K running routes from me that loop from my house. Use OSM data.
It worked for 27 minutes and produced exactly what I'd asked for, as both an embedded visualization and downloadable GPX file and GeoJSON files. Here's that 5K route:

Unread 5.0
John Brayton:
Unread 5.0 is available now from the App Store. This update adds these improvements and more:
- Improvements around hero images, article list thumbnails, and widget thumbnails
- Syncing with FreshRSS and Miniflux
- The ability to quickly mark old articles read
I’m a NetNewsWire man personally, but I’ve long admired Unread as a different, very good take on a feed reader. Just a gorgeous app. One of the very best things about RSS is that feed readers take such different shapes and approaches.
🎬 Melancholia

When melancholia hits you hart, you’re done.
Absolutely love the depressing atmosphere in this movie. And what a scenario with another planet hitting earth!
Love the classic soundtrack. The space images are fantastic. The opening slo-mo sequences remind me of Crewdson photographs.
Part one might be a bit too long, but part two is absolutely perfect.
👍 Recommended!
Quoting Paul Ford
For a while, I must admit, it looked as if software developer roles like mine were done for. How could we fight against tireless robots? But our industry is slowly realizing that making truly cutting-edge software still requires humans to think and work together, to maximize their skill sets and to practice their respective crafts. A.I. can write very good software, but it also makes it easy to do someone else’s job badly, which is part of why all those projects fail. Now that everyone can code, it’s become clearer why many shouldn’t.

Where Are the AI-Generated Killer Apps?

I just want one killer app before we get a killer robot.

Yours Truly on Off Protocol With Jim Ray
atproto.com/off-protocol/2026-09-11-make-your-own-thing-john-gruber
My old friend Jim Ray now runs developer relations at Bluesky, and part of that gig is hosting a podcast, Off Protocol (“a show about building a better Internet”). I was delighted to appear as his latest guest. I generally don’t like talking about my career, but I did enjoy talking about it with Jim. He has that effect on people.
