Enclave: An Unpickable Lock
Just about every key lock in the world today has the same fundamental flaw. They accept input (a key, or a lockpicking tool) from the outside world, and they test if that input is correct at the same time . This flaw opens up two kinds of vulnerabilities.

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…

Weird monitor bugs people sent me in the last 5 years
I develop 🌕 Lunar, a macOS app for getting intelligent adaptive brightness on external monitors and controlling every aspect of your monitor using DDC and other obscure protocols. I get tons of email about Lunar, especially after it became my full time “job” in 2021. A lot of those emails complain about Lunar bugs…

Cheating at chess with a computer for my shoes
I have come up with a new way to win at chess: I have connected up a Raspberry Pi Zero in my pocket to some buttons and vibration motors in my shoes, so that I can surreptitiously communicate with a chess engine running on the Pi.
