I built more with AI agents in two months than the previous year. I used almost none of it. The real productivity gain isn't building—it's using.

Agents didn't kill libraries—they just changed the math
I've been writing software long enough to remember when "don't reinvent the wheel" was gospel. Find a library. Import it. Move on. The assumption was clear: someone else's maintained code beats your o...

Sparking up the blog again and decided to write some inference into the blog. There a few other spots where you can see it in action as well. Check it out.

Experimenting with a Touch ID wrist rest 👀
Early prototype, lots to refine—but the idea feels right.

MCPs give me the same energy as GraphQL: works just well enough that people adopt it, just poorly enough that you inherit a new class of problems.
Both exist because building proper context and tooling takes effort. Most would rather reach for something "good enough."

First custom keyboard build ✅
Split layout, fully custom case + PCB — designed from scratch and 3D-printed. Still a work in progress, but seeing it come together is fun.
Firmware next.

Has anyone set up a self hosted ghost instance using 6.0 and manage to get up with new built in activity pub integration?

anyone know of any good image generation LLMs that are good with icons or generation extension logos. I am surprised this isn't an area of focus.

I was looking for ways to vibe with llms using voice to text in rooms with others.

I wonder which happens first, we start building tools for agents to use to get better context or agents can hook in.
I am surprised the things they do everyday to get context they need.

anyone doing any writing on how to think about what to include in an vector embedding? most advice I read is just throw everything in there. 😬
I know most things will be specific to your project, but would be interested in what people have done.

I just finished printing this cool 3D holder for my desk. It’s a wire holder that keeps my wires from falling off the back of my desk. I think it’s pretty neat!
