Don't shout at your disk drives, warns Sun engineer
Have a heart for your hardware
Those among you who are prone to vocal outbursts of rage at cantankerous kit should be aware that hardware has feelings too, and directing your ire at disk drives can provoke "unusually high disk I/O latency".
That's according to Sun's Fishworks engineer Brendan Gregg, who explains just how to upset your drive on his blog and with the obligatory YouTube vid:
So there you have it - be nice to your drives and restrict verbal assaults to monitors which, as we all know, are specifically designed to shrug off abuse. ®
re: two's compliment
I had to laugh when I read the posts on two's compliment ooperations as both of the previous posters ignored the endedness problem as though it didn't even exist! In my day we had to balance the big endian rigs with the little endian ones so's they complimented each other. We were young in those days and no problem was insurmountable, when I see the kids these days practically counting on their fingers I despair.
Re: Hard drive
Probably, everyone else died when they got doused by an overzealous fire control system.
Am I the only one who remembers having to gently warm IBM drive spindles with a lighter to get them to spin up after a long shutdown?
