It rises and falls. It's right in the title! Perhaps it has little jets, or maybe a particularly specialized form of antigravity.

Wouldn't the performance impact be that of setting the page read-only when the request is submitted, then doing a copy-on-write if the user process does write it? I mean, that's nonzero, TLB flushes being what they are. But they do happen a bunch anyway...

In fact, the Lytro Illum (the big one) had a really nice, very flexible, bright super-zoom lens. If you ever wondered how that was achieved: having the microlens array and a light field sensor (1) allows relaxing so many aberration constraints on the lens that you could have a light, compact super-zoom.

(1) it's not really different focal depths, it's actually more like multiple independent apertures at different spatial locations, each with a lower resolution sensor behind it - stereovision on steroids (stereoids?)

You may be thinking of Andrew Carnegie. Who was a steel industry tycoon, probably the #2 most polluting industry today. Back then - probably #1.

> Look at a modern CPU die. See those frame pointer registers? That stack management hardware? That’s real estate. Silicon. Transistor budget.

You don't. What you see is caches, lots of caches. Huge vector register files. Massive TLBs.

Get real - learn something about modern chips and stop fighting 1980s battles.

Can tell you first hand that while the specs are useful, they do not cover APFS as it is deployed by Apple today.

A distant relative, no doubt, of Stanislaw Lem's "Automatthew's Friend" (1964). A perfectly rational, indestructible, selfless, well-meaning in-ear AI assistant. In the end, out of nothing but the deepest care for its owner's mental state in a hopeless situation, it advocates efficient and quick suicide.

It's not as irrational as all that.

Subway system here has an amazing propensity to send random trains on express tracks, especially during peak traffic. I understand that this is done to alleviate congestion, but the net effect is that when you see a train going somewhere you want, you _seize the opportunity_.
