Deallocated Objects is a static site. A Bun/TypeScript generator on my Mac turns a folder of markdown into HTML, a deploy script copies the files to the server, and nginx serves them. There’s no app process for the blog, no database and nothing to restart. Read more of Scheduled Posts On A Static Site →
As I write this, you can’t pick up an iPhone Duo at any of the 12 Apple Stores nearest New York, Dallas or San Francisco. Every one of the eight configurations says “Currently unavailable” at every store. When units do turn up, the trick is noticing before they’re gone.

Right now, in the top right corner of my Mac, there’s a little cream-colored panel meter with a needle bouncing along with my CPU. Read more of Multimeter, Live Meters For Anything In The Mac Menu Bar →
I wanted to know a few things about this blog. Which posts people read, where they come from, how often the crawlers behind Claude, ChatGPT and Perplexity stop by, whether anyone fetches the markdown versions of posts, and how many people follow along in a feed reader.

Every Mac app I make now ships two ways from the same code. There’s a direct build that I sell on the app’s own website, signed with Developer ID, notarized, packed in a DMG and kept up to date with Sparkle. There’s also a Mac App Store build.

A lot of the people reading this blog now aren’t people. They’re agents: Claude, ChatGPT, Perplexity and friends, fetching a page because somebody asked them a question. This week I spent an evening making Deallocated Objects nice to read for them (and for search engines while I was in there). Read more of Making My Blog Readable By AI Agents →
This blog has been sitting on the same Linode server for a very long time. Deallocated Objects started on WordPress in 2010, moved to a little Rails app I wrote around 2014, and that Rails app has been quietly running ever since on a box I’ve been paying for since 2012.

Yesterday (Wednesday, October 21st) was one of the strangest days in security I can remember. By lunchtime TechCrunch was running a story titled “The internet is having a very bad cybersecurity day”. None of these incidents are connected to each other. Read more of Everything That Broke On October 21st →
Every few days the music on my Mac starts crackling. Pops, little dropouts, sometimes a robotic buzz over everything. The fix has always been the same: open Terminal, type sudo killall coreaudiod, type my password, and wait a second for sound to come back.

A lot of the code running in my apps now was written by an agent. When that code throws in production, the usual path back to a fix goes through me: an alert email, a dashboard, a stack trace I copy into a terminal, and then an explanation of what I think happened.
