Note that the BBC is funded primarily by what's known as a "TV License"[0] in the UK - I think it's entirely possible they could probably increase ads or something for international viewers but understand why it isn't their area of focus [0] https://www.bbc.com/aboutthebbc/governance/licencefee

I believe the bbc provides its shows internationally via other channels, for e.g. https://www.bbcselect.com/watch/take-me-to-titanic/

BBC Select is only in US and Canada, not in rest of world.

Every time I have seen people calling this amateur hour, I wonder if they are right or if it is similar to NASA using the same chip that was used in the Sony Playstation in the early 90s as in the New Horizons probe which reach Pluto in 2015.

Stupid question, perhaps: was/it possible for this sub to have any kind of beaconing or communication system that works at depth? It seems like one of this first things I'd investigate before deciding to build a sub.

I was wondering how naval submarines work when they get in trouble. I would expect to see some sort of emergency button (internally) that you could press, that would release some sort of buoy, that would float to the surface and start transmitting with gps etc. I think that would help narrow down the search. The buoy would be in an external container (to prevent pressure problems), with explosive bolts or something t…

Naval subs in trouble?

They go "forever on patrol." A naval sub is an espionage watercraft; signaling an emergency isn't exactly in the playbook for most of their mission cycle. ;)

My 11yo son asked me why they did not connect a buoy to the submarine with a string. Lol

Do the math exercise with him for how much volume 2 miles of string takes up

Do the math for the weight of a string 2 miles long.

Then take a look at how much weight a string can hold up.

Then you're ready to be taking on space elevators

From what I understand, naval submarines typically have a signaling device called an EPIRB mounted in such a way that it's released automatically if the sub dives significantly below crush depth and/or if a switch isn't activated on some set interval. Then it pops up on the surface and says "Hi, wreck here." I don't think the former system would have worked here anyway, since the sub is supposed to get very close to…

They had this but there were problems with it, if I recall correctly. So it would be disabled in "times of war" or whatever because if it accidentally popped off it was not a good time for you.

"Hi, depth charge here."

The issue most people on Reddit were discussing is that it’s a cheap off brand controller, rather than a higher quality name brand controller (from Sony or Microsoft)

How is Logitech “off brand”. They are well known for input devices.

Their controllers are well known for being garbage. People that take video games seriously can tell you all of the different reasons why they "feel worse" or are just less reliable than OEM. It's a $30 controller where the "standard" option is around $60. The "premium" market where they are custom made for important use cases (ie, competitive Melee tournament) can easily reach into multiple hundreds of dollars, using components like hall effect sensors instead of resistive potentiometers that will lose accuracy over time.

Most people would refuse to play a video game with this controller, let alone use it as a critical component in a vehicle. Joystick drift in a videogame is frustrating. Joystick drift in a fucking submarine is a disaster waiting to happen.
