Getting Ahead by Being Inefficient
Inefficient does not mean ineffective, and it is certainly not the same as lazy. You get things done – just not in the most effective way possible. You’re a bit sloppy, and use more energy. But don’t feel bad about it. There is real value in not being the best.

How I Build
My idea of a vacation might be weird to some. Sure, I like sunshine, I like beaches – but more than all that, I like making stuff with computers.

Rest In Peace, John. I was lucky to know you so deeply
I met John Paragon, Jambi the genie on Pee-wee’s Playhouse, at the improvisational comedy group The Groundlings, where both our careers started. He was sly and wickedly funny. We became best friends instantly. In a group of exceptionally talented and […]

Thoughts on cameras in the age of excellent cell phone photos
I noted here, I believe, that recently my dSLR, my Nikon d750, basically crapped itself, most likely from a faulty mirror mechanism. This wasn’t entirely a surprise to me — it had devel…

What a year of solar and batteries saved us in 2025
Throughout 2025, I spoke a few times about our home energy solution, including our grid usage, our solar array and our Tesla Powerwall batteries. Now that I have a full year of data, I wanted to take a look at exactly how everything is working out, and, in alignment with

He asked AI to count carbs 27000 times. It couldn't give the same answer twice
Ask ChatGPT to estimate the carbs in your lunch. Now ask it again. And again. Five hundred times. You’d expect the same answer each time. It’s the same photo, the same model, the same question. But you won’t get the same answer. Not even close — and the differences are large enough to cause a

Your Move, iPad
Hear that? It’s the sound of Mac fans. No, not your shiny new M1 Mac’s fans—chances are, you’ll never hear those—but rather, the sound of excitement rippling through the Mac community. This is something big. Really big. Now, I’m only 33, but someday when I go full fuddy-duddy I will speak of this: the great…

Dunning-Kruger and other memes (2015)
It's really common to see claims that some meme is backed by “studies” or “science”. But when I look at the actual studies, it usually turns out that the data are opposed to the claim. Here are the last few instances of this that I've run across.

On being ready to die, and yet also now being able to swallow ice cream
Part of being ready to die comes, I think, from psychedelics; I wrote in “How do we evaluate our lives, at the end? What counts, what matters?”: “Bess (my wife) and psychedelics taught me to …

A peek inside Japan's largest “Dagashi” store
Every morning, 67-year Hideyuki Akiyama drives to his store along the rural roads of Okayama in Western Japan. Today is no different. A line of excited customers queuing up before the shutters are open. “Disneyland isn’t our land of dreams, this is!” says one 20-something woman. “This”

I'm an old Mac-head at heart, and I've been using Macs since the mid 1990s (the first Mac I used was an LC II with System 7.1 installed on it). I don't tend to think that the computing experience was better in the olden days — sure, there's a thing to be said about the simplicity of older software, but most of my…
