I've noticed that my computer abilities have shifted since going to work for the Army. I'm probably a better programmer now than I was is college. I've learned new tricks and have access to better programming environments that make the chore easier. But my actual ability to fix hum-drum computer glitches is significantly worse. I suppose this is because I can't fix most major problems on my workplace PC without administrator access (which they won't give me).
My biggest embarrassment came when I reported a problem with one of our printers. The answering question was the obvious "have you turned it off and turned it on again?" Doh! Of course that fixed it. I would have saved the IT group minutes, but more importantly I would have saved me hours.
