July! What a month! Things I did this July Gave a talk, for ClimateAction.tech’s “Responsible AI Series”, “What I know about local language models”. “Responsible AI” can feel like a bit of an oxymoron at times, but I hope I shared something…
In short: I prefer strict tables in SQLite because they avoid some datatype problems, such as putting text in number columns. SQLite has a feature that I think is underrated: strict tables. Strict tables help enforce rigid typing, preventin…
Chicago’s weather is pretty lousy most of the year, but when it’s nice, it’s very nice. June blessed the city with dozens of idyllic days. But don’t worry—I still spent most of the time inside on the computer. Things I did I launched my fir…
As I write this, we’re about 7 sixteenths through 2026, and it’s about 14 sixteenths through the day. For the sixteenth issue of the Taper online magazine, I split time into sixteenths to think about its passage in a different way. The code…
My blog turned 16 this month! I did nothing to celebrate, but made some little tools and clicked some links about tech ethics. Things from me this month I published four little tools this month: ZIP Shrinker, a web app that shrinks ZIP file…

I wrote a simple script that translates text at the command line, completely offline. Here’s an example of how it works on my computer: echo '¿Cómo estás?' | translate # => How are you? It combines a few tools: TranslateGemma, a special-pur…
After a busy March, April was a little quieter. But don’t worry, I still have a bunch of little links for you to click on. Things I published GitHub’s uptime hasn’t been great recently. Even though I dislike the Microsoft subsidiary, I wrot…
In short: GitHub’s downtime is bad, but uptime numbers can be misleading. It’s not as bad as it looks; more like a D than an F. “Zero nines uptime”? 99.99% uptime, or “four nines”, is a common industry standard. Four nines of uptime is equi…
March always seems to be my life’s busiest month. Things I wrote and made “The two kinds of error”: in my mind, software errors are divided into two categories: expected and unexpected errors. I finally wrote up this idea I’ve had for a lon…
