"Of course, I'd also suggest that whoever was the genius who thought it was a good idea to read things ONE FUCKING BYTE AT A TIME with system calls for each byte should be retroactively aborted. Who the fuck does idiotic things like that? How did they noty die as babies, considering that they were likely too stupid to find a tit to suck on?"
And maybe clearly it was important for him to get that point across, to have people consider it; or, of course, reading one byte at a time via a system call is dumb: Since that practice had been going on for a long time, apparently he felt he needed to work hard actually to get the real and meaningful attention of people.
Another way to put it might have been, "What needs to be done, to go around with a 20 gallon barrel of ice water and one person at a time dump it on them to see if they are just asleep or really dead?". When seeing something clearly bad going on for a long time and still little or no outrage, or even effective attention, to improving the situation, can get frustrated and then be crude, rude, etc. if only just to get people shocked enough actually to pay attention.
Maybe I'm not the only one to "feel his pain", and maybe such a statement, under such a circumstance, does not make someone "mean".
The difference being if you cause offence but don't know it will hurt someone you're just rude. If you know it will hurt them and you do it anyways you're mean.
At this point Linus knows how his behavior affects people so to do it intentionally is either ignorant/stupid or mean.
