I Put My Son in a Swamp

Sat, 11 Jul 2026 00:45:00 -0400

My son is a typed resource now. He has a sync method that pulls the last seven days of his life into a versioned snapshot, a stack of reports that summarize how he slept and ate, and — I did think about this — a delete that’s careful to be idempotent, because deleting the same diaper twice shouldn’t be an error.

I did not set out to put a baby in a swamp. It followed, the way these things do, from having already put everything else in one.

The WiFi Certificate That Didn't Exist an Hour Ago

Fri, 10 Jul 2026 18:30:00 -0400

My laptop is on WiFi right now on a certificate that didn’t exist an hour ago. I made the keypair, my own CA signed it, the private key went into my secret store, and the machine authenticated onto the 802.1X network and pulled a DHCP lease — all through code I’d finished writing about twenty minutes earlier. I want to talk about the boring part that made it safe, because the boring part is the only part I’d defend.

Smarthome Soldering Iron with Home Assistant and ESPHome (also: web GUIs for Pinecil)

About a year ago, wesdottoday told me to buy a Pinecil and, once they came back in stock before the holidays.. I did just that… Fast forward a couple months and I’ve got a copr for flashing the Pinecil’s firmware (IronOS), and am spending my weekends playing around with Bluetooth Low Energy (BLE) and Home Assistant to automatically turn on my fan when I start tinkering at my desk, lest my lungs die from the fumes.
