After seeing Sean's video on Action Retro about putting an M4 Mac Mini inside an iMac G4, I thought I'd give it a try. Continue reading 2,454 words...

Pomera DM250 Tinkering posted on march 14th, 2025 with tags hardware and openbsd last updated on july 9th, 2025 The KING JIM Pomera DM250 "digital typewriter" is a small Linux-powered ARM computer that boots up into a custom word processor application. I've been tinkering with it to try to get OpenBSD booted on it. I'd normally wait until the end and write up a proper article explaining everything, but this process is taking a lot longer than I expected so I figured I'd document it all as I go.

Adding Custom Sleep Screen Images to the Kindle Scribe posted on february 24th, 2025 Last year I upgraded my Kindle Paperwhite to a Kindle Scribe to be able to write notes and draw diagrams while programming to help visualize things. One thing that bothered me about the Scribe was that its sleep screen images were pretty boring and because I'm now often reading PDFs or writing in a notebook, I couldn't benefit from the Kindle OS's new functionality that uses the cover of the book being read as the sleep screen image (which previously required a jailbreak and custom software). Since the process for installing custom sleep screen images is rather cumbersome and the information is scattered across old forum posts, I thought I'd document how I did it to possibly make it easier for someone else.

Adding a USB Port to the ThinkPad X1 Nano (the Hard Way) posted on may 29th, 2024 with tags hardware, laptops, and thinkpad I wanted to add an internal USB port to my ThinkPad X1 Nano which should have been a fairly easy thing to do, but it wasn't. Of course, if I were still using my Framework Laptop it would be as easy as plugging in a custom module but I've been using my X1 Nano as my primary laptop for quite some time now.

Advice for Operating a Public-Facing API posted on july 12th, 2023 with tags pushover I've been operating Pushover's public-facing API for over a decade now and I thought I'd pass on some advice for those creating a new API. Pushover's API might be unusual in that it is used by a wide range of devices (embedded IoT things, legacy servers, security cameras, etc.) and HTTP libraries, rather than mostly being accessed from JavaScript in the latest web browsers. It also doesn't process sensitive financial information, so the advice given here may not be applicable to something operating like Stripe's API. Continue reading 1,724 words...
