I started developing professionally on airgapped networks. At night, I was searching stackoverflow for the ideas I had, best practices of what I did that day, how to do things securely, etc. During the day, I cannot access internet because there was just one workstation with internet connection for about 20 devs, DBAs, sysadmins, etc.

And also you cannot copy-paste, so you needed to optimize what you do. Otherwise, you have to write down the exception you had you don't know, then wait for your turn to use the workstation -add log on ceremony with smart cards, etc.

All of those nights, it turns out, I did extra.
