For example, this is what Linus wrote:
"Of course, I'd also suggest that whoever was the genius who thought it was a good idea to read things ONE FCKING BYTE AT A TIME with system calls for each byte should be retroactively aborted. Who the fck 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?
Linus"
Instead, he might have been able to write something like this:"It is a very bad idea to read one byte at a time with a system call, for a variety of reasons, including and especially performance."
I would love to hear how being an abusive asshole actually does any good? I see it as a way to artificially limit the size and diversity of the potential contributor pool.
