Installing a payphone in my house
When I was growing up in the 90s, I remember wanting to get on the Internet. My parents weren’t going to help me, so I called up an ISP and said I wanted to set up an account. They asked for my name and I gave them a fake name. And then they asked for a credit card number and I told them I had to find my wallet and…

FreeBSD on the Graviton 3
As far as FreeBSD is concerned, Graviton 3 is mostly just a faster version of the Graviton 2: Most things "just work", and the things which don't work on Graviton 2 — hotplug devices and cleanly shutting down an instance via the EC2 API — also don't work on Graviton 3. (Want to help get these fixed? Sponsor my work on…

Running Julia bare-metal on an Arduino
I don't really have much experience with microcontrollers. I've played around with some arduinos before and the main entry point for my home network is a Raspberry Pi, but that's about it for recent experience. I did take a single course on microcontrollers a few years back though. I am fascinated by them - they're…

Building my first mechanical keyboard
A friend of mine recently brought up his custom mechanical keyboard while we were hanging out in voice chat, and at first, nobody understood why anyone would buy one. At that time, I had no clue that there are entire communities about building custom keyboards. With every sentence that was said, we got deeper into…

Using a "proper" camera as a webcam
It’s 2022, so many of us now have 2 years experience of online meetings. My experience is that the better that I can see and hear someone in an online call, the more natural the conversation feels. Put another way, I think one does a courtesy to the other person by improving the quality of how you appear in a video…

My Unholy Battle with a Rock64
I’ve got this rock64, which is an aarch64 board comparable to a Raspberry Pi 3 B+ with 4 gigs of ram. For years I’ve wanted to put a distribution on here that doesn’t have a premade image available, mainly because out of all the options on that page I don’t actually like any of them. Well, except NetBSD, but NetBSD…
