I like writing stuff for The Conversation. They take my mangled prose and turn it into really nice articles. I've just written another one for them. You can find it here. It's all about legacy systems.
Above you can see a legacy system I helped to make. We installed it quite a while back and saw it go from "Advanced Touchscreen Magic" to "hard to find the hardware drivers" to "replaced" over twenty years or so. I'm quite proud of the fact that I don't recall it ever crashing. Except that one time that when a chap blew up all the power supplies in the building when he was testing the UPS. And that wasn't really our fault.
