Thoughts about software engineering I can't keep in my head. Too ephemeral for blog posts, too long for social media. It's the messages I'd send if you'd asked me what's on my mind.

Joy & Curiosity #101 (opens the original)
Read excerpt
Last week I was on Matt Swanson’s podcast and we ended up sharing thoughts and vague predictions about programming languages and frameworks. Matt said that he’d be going to Rails World the week after and that he wouldn’t be surprised if DHH said “Rails is over.” Prescient. DHH didn’t exactly say that Rails is over, but, well, some people did call the keynote a “funeral.” But that shouldn’t be surprising, right? The way we’ve treated languages and frameworks for the past, say, twenty years is at

It’s the week of Jev! I’m really, really, really, really excited about it. I mean: really.It’s like someone blew up a confetti bomb in the world of LLMs and now you realize how grey everything looked before. But Jev is not an LLM. It’s a model “built to make fast, structured decisions that software can use directly.” TypeSafe says we should think of Jev “as a frontier-intelligence function call: unstructured state in, typed probabilistic decisions out.”I explained it as a “smart if

Something changed with these latest models, with Fable 5.1 and GPT-6 Astra.The benchmark numbers (79% instead of 65%!) don’t capture it, and neither do the benchmark words: this model goes on for longer than this one, this one is “most aligned”, that one the least “sycophant” (the ultimate benchmark word, no?). At this point? Yeah, whatever.But it feels like we’re now flying at a higher altitude, that we have to concern ourselves even less with earthly matters such as a single unit test or how t

Here’s the start of Chapter 7, ‘Naive Intervention’, from Antifragile:Consider this need to “do something” through an illustrative example. In the 1930s, 389 children were presented to New York City doctors; 174 of them were recommended tonsillectomies. The remaining 215 children were again presented to doctors, and 99 were said to need the surgery. When the remaining 116 children were shown to yet a third set of doctors, 52 were recommended the surgery.[…]Let us call this urge to help “naive in

How many bugs are you willing to tolerate in your codebase?Don’t tell me it’s zero, because we both know it’s not zero. It’s also not a four-digit number. That’d be too much. But there is a number, or a range of numbers. Because we all know that it’s theoretically possible to get to zero bugs, but so far the cost-to-benefit ratio made it not worthwhile. And, on the other end, if the number is too high then your software becomes unusable and you lose customers. (It’s worth mentioning, though, tha
