Sumline Is on GitHub
Before anything else, go buy Soulver. It is the app that worked out the notepad calculator idea, it has been on my Mac for years, and it is one of the few paid apps I would buy again without thinking…
I Stopped Chatting and Started Filing Issues
Chat is a good scratchpad and a terrible filing cabinet. I moved the actual conversation into Gitea issues, and my projects stopped stalling.
The LLM Tax, Revisited: Cost, Latency, and Where to Run the Model
Quality, cost, and latency. You can usually have two. Here is the framework I use to pick which two on purpose, with a voice assistant, an RSS scorer, and a Frigate box as the worked examples.
My AI-Native PM Operating System: Idea to Shipped, Solo
The gap between an idea and a working product used to be an engineering team. Here's the whole loop I run now: spec first, backlog in Gitea, Claude Code doing the building, and me making the calls that actually matter. Including the two features I shipped and then threw out.
Ripping the Keepers, Selling the Rest: The Tool I Built to Clear My Blu-ray Shelf
I've been on streaming so long that the shelf of Blu-rays behind me had turned into furniture. The keepers stayed, and I decided to sell the rest. Selling a few hundred discs one at a time is its own part-time job, so I built a little tool to do the boring parts: scan every barcode, look up what each disc is, figure out the handful worth selling alone, bundle the rest into themed lots, price them, and spit out eBay listing sheets. Here's what it does, and the one pricing lesson that changed how the whole thing works.
What I Learned Shipping a Multi-Agent System
I planned Ceres with seven specialist agents and cut half of them in the first week. The surviving ones still broke, just not the way I expected. They gave me good answers and then quietly assumed somebody acted on them. What that taught me about restraint, state, and where the real work in a multi-agent system actually lives.
Meet Alfred, the Server That Runs the House
For a while my setup was split across two machines. Home Assistant lived on my Synology NAS, alongside the Mosquitto MQTT broker and ring-mqtt, while Frigate ran on a separate custom rackmount PC. It worked, but two things kept nagging…
What Building a Pile of Small AI Projects Taught Me About the PM Job
The tools let me build things I never could have built alone. What surprised me is which parts of the product job got more important, not less.
Nova: Building My Own Echo, One Weird Problem at a Time
I have wanted an Alexa that doesn't phone home for years. Every commercial voice assistant is a microphone in your house wired to someone else's computer, and the whole point of a homelab is that my stuff runs on my…
Introducing Cruxwire: a personal news digest that runs on your own hardware
I read too much news, badly. A dozen RSS feeds, three "read it later" apps I never went back to, and the creeping sense that the algorithm-driven version of all this was optimizing for someone else's goals, not mine. So…
