A Chainsaw at an Axe-Chopping Contest: My Current Agentic Loop

People keep asking me how I actually work with Claude Code now. Not the “does AI coding work” question — I’ve beaten that horse into glue on this blog already — but the boring, practical, how-does-my-loop-actually-work question. So here it is. The whole rig. And fair warning: what I’m about to describe is a chainsaw, and most of the industry is still lined up at the axe-chopping contest.

We've Stopped Arguing About Whether

I just spent a few days at a retreat on the future of software development. Small rooms. Unconference format. Some of the sharpest people in our industry - the kind of names that show up on the spines of the books on your shelf. I’m not going to tell you who was there or who said what. We ran the whole thing under Chatham House Rule: use what you learn, attribute none of it. This is my initial take-away.

Is Waterfall Coming Back? Sort Of. Not Really. Both — And the Bigger Question Underneath.

There’s a thing going around the engineering blogs and Hacker News right now: AI killed Agile, Waterfall is back, write your specs up front, welcome to “Waterfall 2.0.” You may have seen the Medium piece titled Agile Is Dead. AI Killed It. Welcome Back, Waterfall.. Hmmm.

And once I followed the logic far enough, I ran into a second question that nobody seems to want to answer out loud: if the agent writes the code, who actually reads it?

Digital Signage: From Playback to Perception

In recent years, digital signage has become a solved problem: push content to screens reliably, at scale, on schedule. That’s not enough anymore. The market is now demanding screens that perceive — that understand what’s in front of them and respond in real time. Most of the hardware deployed in the field today will fail at that job because the foundational assumptions are wrong. Here’s what’s actually required and why the infrastructure choices you make now will define your deployment for the next decade.
