Ah damn, I loved that book when I was a kid. I can probably blame it, at least in part, for my career…

(I was a massive nerd and a FidoNet sysop back in the 80s & 90s, and got my first VMS and Unix experience hopping onto academic networks over dialup and X.25 gateways using, err, “unconventially obtained” credentials… This experience helped me convince my interviewer at Imperial College to overlook my less than stellar academic record to admit me to their Computing peogramme.

That book - and the movie WarGames - were definitely inspiring, if not life-changing.)
