Just remember back to when some software required the infamous “donegals” to work. They always malfunctioned at a critical time and the producers could never be successfully contacted to resolve the situation in less than a couple weeks .... after blaming you the entire time for their failure.
“Dongles”. Yes, I remember them well. (I have a collection of them as a matter of fact). I used to enjoy removing the need for them from the software. I did a *BUNCH* of them.
OrCAD, 3D Studio, SNMPc, all sorts of apps.
critical time
Like when your John Deere needs the computer tech, and you are miles away in the middle of critical harvest time.
