Turns out I had a `runtimed` from Feb 26 still running. I think it was from an attempt to compile and run it from source. Works now!

nteract native interactive notebooks β€” fast to launch, agent ready, humans welcome.

I downloaded the DMG from nteract.io today, but I can't get past "Runtime unavailable - Runtime daemon not available. Click Retry to connect."

On taste: mine has become markedly less jagged with age. At this point it's essentially boiled down to You Must Believe in Spring. I'm not even ashamed to confess that I was led there by Monocle 10 years ago.

The Silicon Valley idea of taste is about as advanced as its idea of intelligence.

Looks great. I think Pluto.jl's package management is the nicest I have seen for notebooks. Entirely inline, no modals, no sidebars. Maybe worth looking at for inspiration :) plutojl.org/en/docs/pack...

pdit: The Python Un-Notebook for Coding Agents - harry.vangberg.name/posts/pdit-t...

The way I use it is to ask Codex (or Claude) to put all classes and functions and so on in `impl.py`, and only add the high-level interactions to `script.py`, which is the one I open in pdit. pdit becomes sort of a HUD for my agent-written code. Super nice for quick iteration.

Today in pdit: a script to check if the conditions are good for a two-day sailing trip from Jutland to Anholt.

I made this kid's music player app for the iPad 3 years ago, nobody used it, and I removed it from the App Store at least a year ago to avoid paying the Developer Program fee, and yet, it seems like there's a single user somewhere out there who keeps using it, week after week. Warms my heart.

Getting Started with Space Tracer Live coding in Python with PyCharm, Emacs, Sublime Text, or even a browser

Light Table-vibes. Would inline Space Tracer support be possible in Zed? donkirkby.github.io/live-py-plug...

So far I have failed multiple times at making widgets work in pdit … maybe this would help?

Thanks! Your Rust Jupyter projects look super interesting as well.

Today's slightly weird pdit use case: trying out different window configurations for a house renovation.

I've built an entirely new, 100% native, extendable, themeable, modal cmd-space launcher for macOS.

I put a coding agent inside the browser with a single `execute_javascript` tool. Open HTML files -> make changes -> save back to HTML. The HTML file is the source code, the code environment, the app, the data store, everything at once.

I guess I am building a coding agent. Right now. Welp.

I got tired of copying skills and slash commands around when switching between Claude and Codex, so now they are just short sections in AGENTS.md - works fine?

I've heard that decorators are pretty important in Python … so now they work in pdit as well πŸ˜… pdit.dev/news/pdit-0-...

I just released pdit, an output-focused Python editor. pdit takes any regular Python scripts and shows the output side-by-side with the code that generated it. Think of it as a lightweight notebook or REPL for your scripts. Try it right now: `uvx --with "pdit[demo]" pdit --demo` -- pdit.dev

Yeah. I don't mind. But then again, I have, what, three paid apps, so not a good data point.

What I really like is 30-day money back guarantee, like @cleanshot.bsky.social does. As user I get access to full feature set without dealing with badly implemented trial. As business, more reliable?
