Kotlin, by design, doesn’t allow a non-null variable to be left uninitialised during its declaration. To get past this issue, Kotlin’s lateinit allows us to declare a variable first and then initialise it some point in the future during our program’s execution cycle.

This is my personal attempt to formalize observations about […]

If you want to see the blinkenlights, first you should go read my other blog post detailing the finished product. Designing the computer First and foremost, I would need to choose a […]
I’m an embedded systems engineer. I spend a lot of my free time looking for things I could use in future designs, or things that tickle one of my fancies. One of those things is cheap Linux-capable computers, the cheaper the better. So I started diving into the very deep rabbit hole of obscure processors. […]
In previous installments of this series we laid out our state mocking system, and how we built UI integration testing on top of it. In this article we go into depth on how the system is architected, how idle detection is approached, and how errors are gracefully handled. This includes a fair amount of implementation […]
