Video: C Programming on System 6 - A New On-Disk Database Format

It's a new year and my old computer is still old.

A bug in Amend caused it to crash during a commit, which corrupted the repo beyond repair. I quickly came to realize that using resource files as a database for Amend and my new BBS was a bad idea. I NIH'd the problem and created my own file format that will be a bit more resilient to crashes and partial writes.

OpenBSD on the Huawei MateBook X (2020)

My old 2017 Huawei MateBook X has been my most reliable laptop and continued to be my daily-use workstation despite trying half a dozen others (and a desktop or two) in the past four years. Every time I'd try a new laptop, certain components wouldn't work properly, or the keyboard would feel strange, or the screen quality would be poor, or a constantly-running fan or some coil-whine noise would drive me nuts. And every time, I'd return to my trusty MateBook X and everything would just work silently.

I finally have a newer model of the MateBook X and I'm happy to say it lives up to its predecessor and has replaced my 2017 model.

My Fanless OpenBSD Desktop

After the disappointment of my X1 Nano and learning that all future Intel "Evo"-branded laptops would lack S3 suspend, I started thinking about returning to my M1 MacBook full-time or building an OpenBSD desktop. I chose the latter, building my first desktop machine in many years.

Plaintext HTTP in a Modern World

On the modern web, everything must be encrypted. Unencrypted websites are treated as relics of the past with browsers declaring them toxic waste not to be touched (or even looked at) and search engines de-prioritizing their content.

While this push for security is good for protecting modern communication, there is a whole web full of information and services that don't need to be secured and those trying to access them from older vintage computers or even through modern embedded devices are increasingly being left behind.

Bluetooth Audio on OpenBSD with the Creative BT-W3

Fifteen years ago, NetBSD's Bluetooth audio stack was imported into OpenBSD. From what I remember using it back then, it worked sufficiently well but its configuration was cumbersome. It supported Bluetooth HID keyboards and mice, audio, and serial devices. Six years ago, however, it was tedu'd due to conflicts with how it integrated into our kernel.

While we still have no Bluetooth support today, it is possible to play audio on Bluetooth headphones using a small hardware dongle.

Video: C Programming on System 6 - Adding a GUI to diff(1)

In the previous episode I quickly ported OpenBSD's diff(1) but there wasn't any interface to select files or scroll through the output. I've since added a proper GUI with the ability to select files or folders, and in this episode I walk through the GUI and filesystem code and then add a proper Edit menu. I also make a formal release of the code and binary available for download.
