Wild that they manage to fly to the moon but still seem to be having those comms problems. Asking the astronauts if they’re really pressing the PTT button is wild.

In 2D, a bi-rotor is equivalent to the quadcopter in the post. There are 2 thrusts you control to guide the thing.

I don’t really follow. Can you not get the time to the next minute flip and schedule the update 1s after that? How does the lock screen being different prevent that?

> Both experiences use the same Windows kernel system clock.

Ah yes, the lock screen experience. I could stare at it forever.

On a more serious note, does anyone know why they would do it like that? Why is one polling interval aligned and the other isn’t? What’s the security impact?

Can’t you do some kind of mesh? For bats, it doesn’t even have to be very fine.

Asks you to give name and email after you answer all questions to see the score.

Is that already considered bait and switch?

Right, I was talking technically. That’s what I tried to say in the second paragraph.

If you use a regular smartphone in space (or technically in orbit for this argument), it’s probably not going to get a fix because GPS receivers are required to stop locating when reaching some speed to not be export controlled. And that speed is picked so people don’t build missiles, orbital speed will be higher.

Actually not quite correct. The camera and spaceship will generally have different starting positions of their center of gravity but the same starting velocity, leading them to drift apart.

The only real relevant thing for the photograph is rotation though as long as the camera doesn’t float in front of the window frame, and airflow is probably much more relevant for both points than gravity.

You can use a heat pump for any realistic output temperature but the efficiency goes down the higher the temperature difference has to be.

As long as sun and wind aren’t the main energy sources there, it might be economical but I wouldn’t exactly call it reasonable.

Im pretty sure that „Offload Unused Apps“ is on by default.

Well that’s the thing, they won’t know because nobody will do the registration until it’s actually enforced.

If you take futuristic to mean „looking like the future“, it think the second option is sadly more futuristic for some people

F-15 A and C are single seaters. C is actually the most common variant the USAF has.

The one shot down was an E though so two people.

The sword missile is really impressive but you’re not really targeting a single car seat with that.

If you’re the spokesperson, I kind of expect you to think before you speak. I don’t think that’s a HN machine thing.

Then maybe say „I don’t know, let me get back to you“ instead of „no, we built it ourselves“?

Maybe disallowed but definitely not enforced. There’s an app called Pythonista that has allowed you to run arbitrary python code for years.
