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.

My friends and I have been deriving much amusement from the comms issues. We can fly people around the moon, talk with them, send back high res video, but talk to the boat that’s close enough to swim to? Forget about it!

Note: next time, pack a walkie talkie. ;-)


No joke, VHF has been saving sailors' lives for a long time now.

They missed the chance to reply "Main screen turn on."

Just like in the year 3000, we will still ask "Can you hear me?" in video meetings.

I can see your comment, can you see mine?

Cellphone coverage notoriously flaky in the Pacific.

Umm it's a satellite phone.

i was thinking maybe astronauts can be disoriented when splashing down and that's why they figured they should ask if the right buttons were being pushed?

...and informing them which button was the PTT button. She had to say it, but it'd be hard not to react to that.

Good thing they have redundant systems.

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

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?


The security impact relates to the fundamental design architecture of the lock screen.

Similar to iOS Before First Unlock (BFU) security mechanisms being stronger and less capable overall, so too do you see this behavior on Windows.

The user mode lock screen is simply a full screen app, for which glitching the resolution of an “external” monitor which video out ports is often enough to desync the resolution of the full screen lock screen app and the full logged in user desktop behind it. IE: you can just… click past the lock screen app briefly running at a smaller resolution. As you might imagine, there’s a timing aspect to this.

That’s why this behavior exists.


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?

I’ve done clocks like this before. It was sheer laziness. Easier to just set a 30 second update window than to actually compute the time to next update. Particular in some of my sloppier projects without an event loop. Of course, the only person who saw the result was me and it made me chuckle at considering the complexity of managing time well.

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

I asked about this to people who put meshes but they said the mesh goes into the window (it's mostly for mosquitoes), and the open would be outside the mesh, so it wouldn't cover it. I would be OK but I can't find anyone who would be willing to put the mesh on the outside of the window.

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

Is that already considered bait and switch?


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.

That are the tidal forces, they are quite small for a system of the size of Orion.


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

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.
