Heroku: Core Impact
It’s been a rough month for Heroku. On April 15th, they opened a security notice that’s been active ever since – the status page, designed for incidents measured in hours rather than days or weeks, dutifully reads off a duration of “478 hours, 9 minutes” 1 .

Who owns the copyright to my medical images? (2018)
I popped round to an NHS dentist a few months ago - and they stuck my head on one of these contraptions. The Kodak 8000C takes a panoramic X-ray, giving a superior view of your teeth. Nifty. The dentist showed me where my wisdom teeth were and I was impressed with how high resolution the image was. Afterwards, I asked…

Golang Diaries: Generics
My coding time this year has been invested in Quamina , an event-filtering library implemented in Go. Just in the last couple of weeks I spotted an opportunity to bring Go’s shiny new generics to bear, and not just anywhere, but for a central data structure.

A lock-free, concurrent, generic queue in 32 bits
While considering concurrent queue design I came up with a generic, lock-free queue that fits in a 32-bit integer. The queue is “generic” in that a single implementation supports elements of any arbitrary type, despite an implementation in C. It’s lock-free in that there is guaranteed system-wide progress. It can…

Wrong by Default
A few programming languages use a “defer” pattern for resource cleanup. This is a construct such as a defer keyword which schedules cleanup code to run at the end of the enclosing block (or function). This is available in Zig, Go and even in GCC C.

The overengineered solution to my pigeon problem
TL;DR: I built a wifi-equipped water gun to shoot the pigeons on my balcony, controlled over the internet by a python script running openCV reading the camera image of my old iPhone.
