Reading this triggered so many memories of system programming disasters and victories I have seen and participated in: The circular disk output buffer which emulated Ouroboros and eating its own tail, started sending patient data back to the wrong hospital The minicomputer which stopped working (while I was programming it), because a chip had disappeared from the CPU backplane The only soldering I ever committed (which my boss disparaged as really ugly when he returned from giving the demo which that soldering had saved) which enabled me to debug a race condition in a distributed OS I was coding, by creating an RS-232 null modem so I could run two copies of the OS on the same microVAX And too many more to bore you with.
