Aaaand downvotes for this as well, so I guess that means this is not it?
> Please don't comment about the voting on comments. It never does any good, and it makes boring reading.
Folks downvote comments about downvoting because it's boring to read, and to discourage others from doing it.
Early downvotes can happen through accident or randomness; all it takes is one or two people to misread your comment, or mistakenly tap the down arrow. Or they might have a valid reason for disagreeing and are in the process of writing a comment putting a different point of view.
But getting offended and defensive and editing your comment to complain about it only makes the original comment worse, and leads to an off-topic subthread like this.
Sure, edit the comment if you need to, but try to make it clearer and more informative; that's what I do if I get an early downvote and realise the comment could have been better-worded.
To contribute, the PREEMPT_RT has been around as a set of patches(if not this specific one, then at least some version of making linux a realtime os.). If you need to know that something will run within a specified amount of time realtime matters.
EDIT: Don't use this and think it will help performance, generally it kills throughput.
And adding "offensive" every other sentence [1] assumes (for me at least - for others not that much) that you are talking about us as crybabies being easily offended. I almost downvoted for positioning yourself as a purveyor of ethics with the implied assumption that everybody will agree with you.
But in general people around here indeed _are_ easily offended - see for example 'rzv' in this thread being downvoted for talking about this very problem. Depends of course on the thread and on the self-selected audience.
So - what can you learn from a downvote? For me is: don't debate here - HN it's not a platform suitable for debating ideas.
