One of the really interesting areas of work on practical performance that I was pointed to years ago was cache-oblivious algorithms. Haven't heard much about them recently, but maybe I don't pay attention to the right things.

BTW, were you counting x86 instructions by the opcodes or the mnemonics? I'm guessing the latter.

Yeah, familiarity with a system often means you know which parts will be important for performance.
(Also, thinking only about asymptotic performance is a problem; O(N log N) may well be faster than O(N) for all values of N that fit in the machine's memory.)

Would additional color bands at the high end help distinguish them? I suspect it might separate SF from the rest.

@California_HCD should nix this plan unless SF:
(1) backs up its "pipeline" & "mayor's office" projections w/ public data, &
2) commits to ministerial review + waiver of fees/exactions/standards that render projects economically infeasible until city reaches RHNA target.

CSS Selectors and XPath were built/optimized around different problems:
selectors: given an element and a set of selectors, which selectors match?
XPath: given a set of elements and an XPath expression, which elements match?

I think the biggest problem is probably mm.icann.org/pipermail/tz/20…
... but see the rest of the thread.
That said, my suggestion is half tongue-in-cheek because if you turn it into something practical, you'll end up with Daylight Saving Time or something a lot like it.
Structuring my sleeping/waking schedule around sunrise makes more sense to me than structuring it around noon. I think waking up around sunrise is sensible, and having dark in the evening before bed feels normal.
Switch to sunrise-based time rather than noon-based time! (Just define 6:00am as sunrise, and some days go from 5:57 to 6:00... or 5:62 to 6:00.)

For the second pandemic anniversary, I wrote a plausible what-if.
What if the world reacted quickly to the available information, like Taiwan or South Korea did?
Lancet calculates ~18 million lives lost to Covid. Many, maybe all, could have been spared.

But was it internationally shipped learning materials that have an address of origin printed on the side of the box that appears intended as a show of status?
