What I'm thinking about right now.
Why I chose Unsloth (before training a single token)
Honest note up front: I have not yet fine-tuned anything with Unsloth. I have not run a single training job. What I did is spend three weeks researching fine-tuning frameworks before writing a line of training code — and at the end of that research, I picked Unsloth and committed to it. This post is about why. I'm writing it now, before I start, for two reasons. First, so that if this decision ages badly I have to own it public

Why I'm fine-tuning a small model (and why it runs on your laptop)
I'm training an AI model. It's going to run on a laptop. Three weeks ago I would have told you I was training a 70-billion-parameter model, the kind of thing that needs a data center to breathe. I'm not. I'm training a 4-billion-parameter model that runs on a Mac Mini. If the smaller one works, a larger companion model may follow. But the 4B is the bet. This is the first post in a series where I'll share what I'm building, why,

Read essayHow 0% APR Credit Cards Actually Work — From the Other Side of the Desk
A few years ago I was working with a homeowner in Tennessee who needed $35,000 for a renovation project. He had one requirement: 0% APR. Wouldn't consider anything else. We found him a card with a 21-month intro period at 0%. Best terms on the market. He applied, got approved — for $20,000. Not $35,000. Twenty. Now he's got a $15,000 gap and no plan for it. But that wasn't even the real problem. The real problem was that the ca

I Tried to Buy a Mac Studio This Week. Here's What Happened.
I've been running our AI stack on a rented L4 GPU on Google Cloud. $700 a month. Serves a Qwen 14B model. Fine for production. Not fine for what I want to do next. I want to self-host a 70B open-source model on my own hardware. Run it locally. Write about the whole process in public. Eventually help other founders do the same. The plan was simple. Mac Studio. M4 Max. 128GB unified memory. Quiet enough to sit on a desk. Fast en

Things You Can't Install From a Prompt
I killed most of my businesses in December 2025. The SaaS. The acquisitions. The MRR goals. The courses and playbooks. All of it was sitting in the kill zone - information products, tool products, advice products. Everything AI was eating for breakfast. A few years ago, you could build a business around knowing things other people didn't. You could package expertise into consulting engagements and courses. You could be the per
