Some thoughts on upgrades and Mint Debian

At some point in the future historians will be able to look back and pinpoint the exact date when updating your PC went from being a good idea to a bad one.

The operator would approach the computer with a written list of what switches to press and in what order, and by the end of the switch-pressing session – provided the operator had got it right – the computer would have possession of both the data and the program it was supposed to run. Naturally enough, computer programmers soon got tired of switch-flipping, and better ways were devised to store and enter information. Read the rest of this entry »
