Vibe coding and agentic engineering are getting closer than I'd like

Vibe coding and agentic engineering are getting closer than I'd like

I recently talked with Joseph Ruscio about AI coding tools for Heavybit's High Leverage podcast: Ep. #9, The AI Coding Paradigm Shift with Simon Willison. Here are some of my highlights, including my disturbing realization that vibe coding and agentic engineering have started to converge in my own work. One thing I really enjoy about podcasts is that they sometimes push me to think out loud in a way that exposes an idea I've not previously been able to put into words. Vibe coding and agentic…

Eating My Own Dog Food: How I Used the Framework to Write the Post About the Framework

Eating My Own Dog Food: How I Used the Framework to Write the Post About the Framework

In “Don’t Automate Your Moat,” I argue that engineering organizations should match AI autonomy to two independent dimensions: business risk and competitive differentiation. I used AI Gateway cost controls as a worked example throughout the piece because a single feature touches all four quadrants depending on which piece you’re building. A piece making that argument […]

datasette-referrer-policy 0.1

datasette-referrer-policy 0.1

Release: datasette-referrer-policy 0.1 The OpenStreetMap tiles on the Datasette global-power-plants demo weren't displaying correctly. This turned out to be caused by two bugs. The first is that the CAPTCHA I added to that site a few weeks ago was triggering for the .json fetch requests used by the map plugin, and since those weren't HTML the user was not being asked to solve them. Here's the fix. The second was that OpenStreetMap quite reasonably block tile requests from sites that use a…

Our AI started a cafe in Stockholm

Our AI started a cafe in Stockholm

Our AI started a cafe in Stockholm Andon Labs previously started an AI-run retail store in San Francisco. Now they're running a similar experiment in Stockholm, Sweden, only this time it's a cafe. These experiments are interesting, and often throw out amusing anecdotes: During the first week of inventory, Mona ordered 120 eggs even though the café has no stove. When the staff told her they couldn’t cook them, she suggested using the high-speed oven, until they pointed out the eggs would likely…

llm-echo 0.5a0

llm-echo 0.5a0

Release: llm-echo 0.5a0 New -o thinking 1 option to help test against LLM 0.32a0 and higher. This plugin provides a fake model called "echo" for LLM which doesn't run an LLM at all - it's useful for writing automated tests. You can now do this: uvx --with llm==0.32a1 --with llm-echo==0.5a0 llm -m echo hi -o thinking 1 This will fake a reasoning block to standard error before returning JSON echoing the prompt. Tags: llm

Quoting John Gruber

So it’s well known that Y Combinator owns some stake in OpenAI. But how big is that stake? This seems like devilishly difficult information to obtain. I asked around and a little birdie who knows several OpenAI investors came back with an answer: Y Combinator owns about 0.6 percent of OpenAI. At OpenAI’s current $852 billion valuation, that’s worth over $5 billion. — John Gruber, Y Combinator’s Stake in OpenAI Tags: openai, y-combinator, ai, john-gruber
