Gpiozero Flow
Back in 2015, I had the idea for gpiozero — a Python library for Raspberry Pi, making programming GPIO devices simpler by abstraction: instead of thinking about pin channels, voltages, pull-up resistors and rising or falling edges, we think about buttons being pressed and released, sensors...

One day there will hopefully be a house on this land Over the last year, I admittedly haven’t used my Vision Pro a ton, but fairly recently I discovered a super handy use that it’s absolutely incredible at, provided you have the right tools.

Turning a dumb AC unit smart (without losing my security deposit)
TL;DR: DIY home automation is ezpz with nothing more than a stepper motor, an esp32, and a high tolerance for Jank. My rental apartment’s AC unit can only be controlled using these retro-looking analog knob-based controls, mounted right onto the unit. No separate wall-mounted thermostat, no remote…

Developers are attached to tools because tools encode trust
The tools themselves are new and their capabilities are in constant flux. If your kitchen knife kept changing shape, weight, and edge, you’d have to relearn it every time; that’s a hard tool to build trust in. But it also points to a flaw in how you use that tool, the process around it, and the way the tool reinforces…

San Francisco: Don't Fall for Industry Defense of Surveillance Pricing
The concept of “surveillance pricing” is just one part of a much larger problem and business model: corporations maximizing their profits by invading our privacy. The all-too-common business model is to systematically harvest, collate, and store as much of our personal data as possible, and then...

That time when I failed the Microsoft interview
The year was 2015, halfway through my Computer Science bachelor’s degree. I had spent a few months contributing to open source and my confidence levels were high, so I thought: why not aim for a summer internship at Microsoft? Microsoft, of all places, might sound like a weird company to target in 2026. Back then…

User Interfaces of the Demo Scene
Ahh, the demo scene - a digital art subculture, a motley gang of creative nerds, and a favourite pastime of mine.
