My 19-year-old asked me if I found my job hard. I thought it was an interesting question and I had to think about it. After discussing with a colleague, he created the best analogy. He said our kind of work is “hard like an escape room with friends”, not “hard like hard math.” I think thats right. 

I’m having a very emotional reaction to relitigating COVID. Trying to vilify those who said, “there’s a lot of uncertainty but here’s our best understanding today” is making me feel angry. I’ve spent so many years in risk management I guess I empathize with those who were trying to sense make & warn

I ran an experiment yesterday where I used OpenCode to try and build a pretty big project with limited interaction during the build. I created 14 design documents outlining how it should all work. This morning there were few code errors, but I discovered lots of inaccuracies in my design docs 😵‍💫

I've found that if I lay down really strict guides and a a very thoughtful design document, frontier models make a fast and very useful first draft of software. One of my devs was like, "yeah, they are like compilers that deal well with ambiguity" 🫠

Like so many critics, I’m angry about the movie Odyssey because this one thing I remember from reading simplified translations of Homer in middle school was the cyclops yelling, “nobody is killing me!!” and that wasn’t in the movie, rendering it historically inaccurate and woke.

yeah this was my 1st agentic code use case and it continues to be super valuable. I start with asking the tool to document the architecture and general flow of the code. Then next pass I ask it to document the user experience flow through the code. At that point it has context and has future context

I suspect once we figure it out agentic work in software will actually be a huge aid to codebase comprehension This is such a wildly unpopular thought right now but you know what I'm going to pre-register my belief in this possibility

Claude is really good at refactoring an accountant generated high maintenance spreadsheet into reproducible code. One of the most high leverage uses I've seen in practice is getting accountants out of data munging and clumsy biz logic
