You can get much more useful info out of Activity Monitor by running spindump. For iOS the Battery settings are usually good at telling you about power drain.

I don't think the Battery settings shows you power usage by system daemons?

Personally I believe that earth is flat disk carried by 4 elephants, which are standing on the back of a giant turtle

Sure, but that turtle is carried by four "elephants, which are standing on the back of a giant turtle". And that turtle ...

The Hindu sees a recursive algorithm. The flat earther cant see past the stack overflow.

What the hell? What if you miss your turning or want to do a u-turn? Going around more than once is a perfectly reasonable thing to do.

What if it's a magic roundabout? [1] [1] https://en.m.wikipedia.org/wiki/Magic_Roundabout_(Swindon)

It looks like a pinball machine with bumpers and flippers!

This is due mainly to our tilt, not our sphere-ness

On a spherical world with no tilt, what time is sunrise at the north pole?

Depends on the angle of the ecliptic

Falsehood #2: Every day starts at 12:00 am midnight.

Because there is neither a 12:00 am, nor a 12:00 pm. One is 12 noon, the other is 12 midnight. AM and PM are "ante meridian" and "post meridian": before" and after . But 12 is on* the meridian; neither one. You can meaningfully say 12:00:01 am, or 11:59:59 pm, but for 12 sharp nobody can say whether am or pm is dark or day. Airlines schedule flights at 12:01 for this reason.

OU4483 leaves CPH at 1200, as does another flight.

There isn't a flight at midnight, but there are fewer flights then anyway, and it may be confusing to some which day the flight is on. Of course, the flights around midnight have departure times of 2350 and 0015.

I sometimes wonder how many bugs are lurking in systems using GPS for navigation at 180th meridian (where longitude goes from 180 to -180).

I crossed the antimeridian several times on a trip last year. I usually carry a GPS logger on such trips, to contribute to OpenStreetMap.

My USB logger was OK, but my backup logging apps both added crazy points around the world.

Programs to display / edit the tracks also had bugs.

Even Google Maps has defects on the maps at the antimeridian.

It’s not specific, but it’ll say “System Services” I believe.

On Android you used to be able to open a terminal and run "top".

With the improved security model, that now only shows the bash and top processes.

Depends on the state/country, but most have rule that you can't go around more than once. In fact, most places I've seen in the US you can't even go more than 3/4s around (although I'm not sure if that's a law or just a posted suggestion).

What the hell? What if you miss your turning or want to do a u-turn? Going around more than once is a perfectly reasonable thing to do.

On a turbo roundabout, you can't.

The F-22 had such problems.
