This week: Axle 0.30, new docs; Sunnyday gains skills

Axle 0.30 is a big milestone in a few ways:

This week: Sunnyday Sandbox resume, Assistant; next Axle CLI?

On the Sunnyday side:

Prototyping the SDLC

AI generates code an order of magnitude faster than any human can. Hand-writing code is no longer a tenable proposition, and so the effort has shifted to doing whatever we can to hold AI code to our own quality bar. Some hand wave it away, comparing it to the evolution of C over Assembly, arguing that over time AI is going to be so good that we never have to think about the lower level code…

This week: Sunnyday pruning; codebase knowing.

The week was all about trimming and pruning. Sunnyday went through an AI code review and came out with roughly a thousand lines less. Most of the savings came from the deletion of duplicated logic, and many of that from AI code written across different sessions.

A Framework for Agentic Success

I wrote this down a few months ago while working on Sunnyday. Recording here for posterity.

This week: Axle 0.28.0; evals, experiments.

Axle 0.28.0: a release long in the making focused on completing the compaction API and steering (changelog).

A new resolve?

I’ve been thinking about what kind of work I want to do next. It then occurred to me: instead of thinking about problems, I can just work on them. The cost of making is dramatically lower these days, why not spend the time trying things and getting hands-on. The trick is picking problems small enough that I can finish. I’ll write up and post my findings here, so that I actually do.

The Law of Conservation of Complexity

Everyone else is talking about evals these days. Unsurprisingly, since we are at the phase where AI adoption is hitting critical mass.

Keeping up with the Robots

This morning, I was multitasking. I spent a few minutes making Claude Code go, and while it’s revving I’m writing in my paper notebook. Something catches the corner of my eye, I looked up and went to tend to the AI’s request. It whirls again, so it’s back to the notebook. Back and forth. As you can imagine, neither turned out particularly well, although if I were to be fair, the robot did a much…

What Is Everyone Actually Doing With AI?

A survey of 107 about how people use AI

In no particular order

I love designing and building UIs. Like love, love. It is work that combines product thinking, UX, systems, and visuals all at the same time and it tickles every part of my brain. There are easily five iterations to get to a satisfying outcome: original idea, wireframes, implementation, iterating through the trough of disillusionment, and then the transcendence. I’ve gotten to a good state with…
