New accounts are pretty much invisible here on twitter.... Trying to get past 50 views. Should I give up, or continue to post every day?

Code refactoring is how software evolves. AI agents can write code. But can they learn when a codebase needs refactoring—and how to do it well?

How do I get more followers? I got +3 in the last day? You?

Do you know the answer?

One underrated use of AI for studying: Ask it to deliberately give you a plausible wrong answer and make you find the mistake.

Why do digital textbooks still look like PDFs? We have animation, simulations, instant feedback, interactive diagrams, and AI. Yet much of digital education still means scrolling through pages of text. What will it take to truly reinvent it?

What should a good AI agent do when a student asks for the answer? A. Give it B. Give a hint C. Ask a question D. Refuse until they try

Here’s the dilemma I keep running into when writing skill files — or vibe-coding them: How do I know that a change I describe in plain English will actually produce the behavior I want, without introducing some unexpected side effect somewhere else? It reminds me of something I experienced in college. I first got BA in math & physics, then went on to study philosophy. My first year in philosophy was incredibly frustrating. There were so many competing ideas, often contradicting one another, and it wasn’t always clear which one was “right.” Math and physics felt different. They were deterministic. Change an input, follow the rules, get the result. Skill files increasingly feel more like philosophy than math. So how do we test plain-English instructions with the same confidence we test code?

I tried vibe-coding a skill yesterday. It was much more frustrating than I expected. I’ve been a software engineer for 25 years, and for the last year and a half I’ve used AI heavily to help me write code. But I would still review every change it made. Vibe-coding a skil felt different. I couldn’t realistically review every change because the “code” was mostly Markdown files, and changes could be scattered all over the place. A small instruction in one file could affect behavior somewhere completely different. And that creates another problem: how can I be sure a change actually improved the system instead of just fixing one thing while introducing some strange behavior somewhere else?

It’s definitely more fun to have a co-founder than to do it solo! Couldn’t agree more. And companies with co-founders tend to have a better chance of succeeding.

I think the idea of a "one-person company" is overrated Yes, a person can do a lot more thanks to AI. But building something new can be a profoundly lonely experience. You need someone to brainstorm together, suffer together, celebrate together... It is extremely easy to lose motivation when you don't tie yourself to the mast together with somebody else
