How well do agents use test/verification techniques?
We previously noted that, while it's easier than ever to hit a particular quality bar by having coding agents use effective test techniques, software quality seems to be getting worse , indicating that whatever defaults developers are using may not work very well. Here, we test if simple instructions to agents to use…

Your intellectual fly is open when you use an LLM to author a post (2025)
I need to make a painful confession: somehow, LinkedIn has become an important social network to me. This isn’t necessarily due to LinkedIn’s sparkling competence, of course. To the contrary, LinkedIn is the Gerald Ford of social networks: the normal one that was left standing as the Richard Nixons and the Spiro…

AI, Tools and Transformation
It’s very tempting to imagine that AI turns everyone into a tool-builder - now everyone can just ask the model to make the software they need, and apps as we know them are dead. I think that misunderstands how most people think and where software actually comes from, and more importantly, it isn’t

Three sites made 215,128 “best software” pages for AI. Perplexity cites them
Across 380 software categories, 59.8% of the sources behind grounded AI recommendations sit outside the 100,000 most-visited websites, and several of the most-cited are sites built to be read by models rather than by people.

How accurate have Ed Zitron's AI skeptic predictions been?
I was curious how well the predictions of the most widely cited AI skeptic I've seen (Ed Zitron) have done, so I looked at how his predictions panned out. To disclose my own biases, I've never had a particularly strong pro or anti AI progress position. For example, in 2022, I did a comprehensive look at predictions…

I accidentally turned LLM memory into program analysis
Why I stopped trying to give LLM agents a better memory and instead built Lemmalog, a Datalog engine that maintains an agent's knowledge as analysis state, with provenance, retractions and incremental evaluation, plus what happened when I benchmarked it on LongMemEval and LoCoMo.
