Hacking in the way presented in the article is vandalism. A door being unlocked isn’t permission to enter. A lock with a flaw doesn’t mean it can be removed.

For the earliest hackers, it was all about puzzles.

In addition to computers, other common obsessions were lockpicking (mechanical computing), model railroads (electricity + switches + relays), and Chinese food menus (language skills).

The plains have been settled, the pioneers are all dead.

I still use the old form and don’t mind too much if anyone gets the wrong idea. It’s a good way to find other like-minded people.
