I have a pet peeve I would like to share with you all: people who swear, shout and rant at their computers. I've known quite a few in my time. One of the guys at work (who is probably reading this) is a particularly big fan of calling his computer names. The other evening my sister was doing likewise and my dad has his moments. This rant is aimed at anyone who shouts at their computer.
I would like to start by explaining that computers are machines. They don't think, they don't feel, they don't get happy, or sad, they don't suffer bouts of laziness or get the urge to do something mischievous. They do exactly what they're told. They don't try to second guess, or improvise, they don't respond to criticism or praise. You tell them what to do and they do it.
If they're not doing what you want them to do it's because either you haven't told them correctly, or someone else has told them not to do it. So next time you're thinking of abusing the screen, take a deep and realise you fucked up, not it.
