Top Three 2025 - The best books I read in 2025

I finally picked up reading again after a few years off. Though I didn’t plan for it to be this way, my top three turned out to be older books, with an average age of about 53 years since publication. 1. Cannery Row (1945) One book that almost made my list was Whalefall: A Novel. Part of it takes place on Cannery Row, the historic waterfront in Monterey, California. Whalefall got me interested in…

Learning Assembly by building Space Invaders

I’ve had a goal for the past 3 years to learn Assembly language. This December I had some time off, and finally put in serious effort to see if I could finally get somewhere with the it. I followed the tutorials in Oscar Toledo Gutiérrez’s book “Programming Boot Sector Games” to create a version of 1978’s Space Invaders. This one is Christmas themed, and you can play it below.

People who are really serious about blogging should make their own blog

I like this quote from Alan Kay: “People who are really serious about software should make their own hardware”. I’m not really that serious about blogging, but I still think if you can make your own blog you should.

You can learn a lot by building a coding agent, part 2

In Part 1, I described Shade’s router and how it plays an important role in a local-first, multi-model agent. In Part 2, I show the context management system, arguably the most important component of the system.

MCP and the early-adopter tax

It’s 2025 and we’re smack in the middle of an AI hype cycle. What I’ve learned over a few decades of being an early adopter is that while it’s fun to try out new things early, you end up looking back and wondering if some of it was worth the time and headache.

You can learn a lot by building a coding agent, part 1

A few weeks ago, I built my own command line coding agent. There are a few reasons I started this project, sorted here in an honest order.

Input/Output

In 2023, Andrej Karpathy tweeted that “The hottest new programming language is English”, referring to how we’re able to prompt AI to generate code instead of writing it out line-by-line. But the irony is most of us are using this “new programming language” the same way we used the old ones, pecking away at keyboards to translate our thoughts into text. Lately, I’ve tried talking instead.

We’re not vibe coding enough

Viberank is a leaderboard that ranks developers by how much money they spend on Claude Code, Anthropic’s AI coding agent. For the month of July 2025, the top 5 participants spent an average of $9.6K apiece; that’s basically $115K/yr to have an AI assistant help them build things. To put that in perspective, 2025 Glassdoor estimates the median annual salary of a developer with 1-3 years experience…

Persuasion machines

In 2024, a group of leading experts in artificial intelligence, including Yoshua Bengio, Geoffrey Hinton, Yuval Noah Harari, Dawn Song, and more published a consensus paper in Science articulating their shared concerns (and recommendations) about the risks associated with the rapid advances they were seeing in AI…
