alt Hacker NewsThis has absolutely nothing to do with what I said. I wasn't referring to people who think that program performance doesn't matter (although I'm sure there are many of those) but to people working on code that either doesn't impact the overall program's performance much or it does but not due to layout. The number of developers working on code where layout is a major contributor to performance is relatively low, and this includes people working on programs where layout does impact performance significantly (because even in such a program, that particular hot path is not touched by every developer).

And that's the problem. Who decides that? How do you know and that's my problem with it. Things always change. It's always temporary, not in the hot path, doesn't matter etc until it does.
So what is considered "doesn't impact" often comes back to bite.
