Tragic Titan submersible’s $62 SanDisk memory card found undamaged at wreckage site

Certainly interesting to have an algorithm that is extremely lossy (near totally) for the majority of inputs but lossless for some weird edge cases.

funny how you downplay it all the way till the end, and anything surviving 1000s of Gs is incredibly impressive.

I will never buy another Sandisk product. They are as unreliable as cheap microcenter flash drives now. I’ve been burned too many times, and couple of those time were literal burns too!

Be better

TIL it’s okay for kids to die if they’re privileged.

People outside the company knew it was haphazard?

In older articles they stated he did not want to go and they never gave his age. Were they early attempts at propagandizing sympathy for the rich?

But they put other people on those rockets, not themselves.

How many atmospheres can this ship withstand?

Well it’s a spaceship airplane, so I’d say anywhere between zero and one."

So his goal was to make a deep sea taxi of sorts. Rich guy affordable and capable of carrying more than 1 or 2 people at a time. Based on what I’ve read and seen he had two main reasons for the design:

1. Titanium/steel would’ve been too heavy and required a different design.
2. A sphere has too little volume to carry the number of passengers he wanted so he used a cylinder.

His use of CF was not only mostly untested but where it had been tried it was found lacking. It is strong in one direction but not others. The manufacturing process was very difficult and fraught with issues. Making such a large component that thick meant many many wrappings that had to be precisely done. For instance, they would get bulges that had to be reduced immediately or they’d amplify with more wrappings. So they would grind down those spots and wrap over them. The problem here is now you’ve broken the fibers and created end points and fracture initiation points. Things like the junction between the metal end caps and the CF tube were also an issue.

He was very cocky about how often you could reuse the vessel and tried to be cheap on testing which would involve sacrificing vessels. At 5,600 PSI small things that you could ignore in, say, an airplane structure, become wildly amplified.

Personally I didn’t see the point of the whole trip except for bragging rights. You’d be watching most things on a monitor anyway and your porthole was this little, very thick, acrylic hole. You might as well send a robot down and watch on a screen on the ship.

What sensors do you think this was recording data from?

Bricks? I used mine to process diamonds. Cracked them up real good. It still had its shine, too.

Yeah. One of the rich guys brought his son. Reported as “university aged” but still.

Over 18, but still young enough to not be predestined to become like the other billionaires I guess.

Over 18, but he was the only one that doesn’t want to be there. He was scared but didn’t want to disappoint his father. That poor kid and his mother. Can’t imagine how she must feel. This is why being a good parent takes more than resources. I would never want a relationship with my kids where they felt pressured into doing something just to make me happy. I’d hope I’d make different decisions as a father if I was in that situation. My son openly tells me about his hesitant feelings towards an objectively dangerous trip, I’m not making him go at the very least. And I’m probably not going myself because me and my son can do something else together.

One was a kid, one was a person who spent a chunk of her life saving for a ticket.

Most of them were just regular people.

let’s be honest the biggest boat i’ll ever have is a 7 foot tin dinghy

Yeah I know but marketing is marketing. It doesn’t really have to make any sense.

If the Xbox controller had survived I’m sure Microsoft would have made big of that even though it’s basically irrelevant to the product.
