It’s interesting how relative this is, reading by the comments and stories around them. A previous coworker started computing in the punch card era and would tell stories of dropping your stack of cards and having to reorder them, using the printouts to debug, and so on. And helping develop what’s now known as fork() for processes (although it predated fork and he had his own name for it), and helping develop a commercial RDBMS before they existed all in a non tech industry career.

So when I read about Exchange Server to me it still feels quite modern.

My father has told some stories about waiting in line to run punch card programs and people dropping their stack and becoming flustered about it. They're funny to hear and mentioning it because this is the first I've ever heard it mentioned elsewhere.
