I've spun up an old ubuntu laptop recently for.. reasons. I think the last time that machine was in use was in the late 2000s. Poking around on it, I was blown away how simple and resilient the infrastructure of some of my old projects was. Things just build, things just work -- after over a decade of being mothballed.
Did the projects work in just the laptops? Or did they work elsewhere also? I think its fairly easy for existing old projects to work, as long as the hardware it lived in is easily replicated. Not so if you have to port it to modern hardware
