Developing a BrightSign Extension

Most people think of a BrightSign player as the little box behind a screen that loops a video. That’s true right up until you realize the thing is a full ARM64 Linux computer with an NPU sitting idle most of the day. And you can run your own code on it. Natively. That’s what an extension is, and once you grok it, a whole world opens up.

The Chainsaw I Built Was for Learning. Superpowers Is for Scaling.

Last post I showed off the chainsaw I built myself — my build-autonomous loop, the padded room, the whole rig — and cut down a little tree with it: a Go CLI to boss around a smart plug. It was well worth building! I also think you should probably stop building your own. Yes, including me. Especially me.

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.

The Future of Software Engineering: What I Know and How I Know It

A recent industry retreat of senior engineering practitioners published their findings on where software development is heading. Reading it felt like someone had been reading my mind — and the minds of the people I follow online — and synthesized it all into one document. When a lot of people arrive at the same conclusions independently, that’s signal worth paying attention to. Here’s my take on each major theme.

What Would Grace Say?

Grace Hopper built the first compiler in 1952. They said “you can’t make them understand English-like instructions.” She had a running compiler and nobody would touch it. Sound familiar? Grace had some thoughts about this kind of thinking. She had a lot of thoughts, actually.

AI-Boosted Building - It's All About Agency

A Scottish football manager once said, “Some people think football is more important than life. But they are wrong. It’s much more important than that.” When intelligence becomes a utility, the ability to ACT on it becomes everything. In today’s software world, Agency is more important than anything else!

Don't Miss the Train!

The AI train has left the station. Some of us are on board, generating entire modules from specs. Others are still on the platform debating whether the train is even real. Four smart people wrote about this shift this past week. They all agree on what it means. And I agree with them.

Vibe Coding Book Review

I don’t like the term “vibe coding.” I strongly prefer “AI-assisted software engineering.” But regardless of what you call it, Gene Kim and Steve Yegge have written a book about it - and their journey from skeptics to true believers is the most interesting part.

Using Claude Code to Build gocat

In my previous post about Claude Code, I talked about using VS Code devcontainers to safely run Claude in “dangerous mode.” That was great for a typical software project. But what about something harder? What about porting a complex hardware-interfacing library from Python to Go, where you need to deeply understand USB protocols, radio registers, and firmware internals?

That’s exactly what I did with gocat – a Go library for controlling the YardStick One sub-GHz RF transceiver. And Claude Code was instrumental in making it happen.

From Clicking Yes to Letting Claude Run Wild (Safely)

So I’ve been working on this project called client-w-mcp – it’s a leanring project to truly understand how an AI agent works with MCP servers. And I’m exploring Agentic development - with Claude Code. Why Claude Code? The first time I used it, Claude just… flowed. It seems to do a lot more by itself to figure things out. I especially like the Task() so that it can go do more than one thing at a time.
