I am blown away that there is any overlap between HN readers and people getting gotten by this clickbait. The controller is sending control signals to the computer which controls the motors. The controller itself is basically irrelevant . It’s not actually doing the control, the motor controllers are. Using off the shelf stuff like this is also common since it’s extremely well tested and usually very physically robus…

Yes, if one had the budget to do all those things, from scratch, better than an existing component manufacturer. Not many companies have NASA levels of "throw money at it until it works, and every part has been signed off on five times." Absent that, I'm having trouble seeing how custom > COTS. In all probability, anything in-house would have been worse and added new failure modes. Better to buy, analyze, and adapt a…

NASA isn't producing in-house, they still source from third parties. So, if you want, or need, something from scratch, you pay for the development and industrialisation and then for the parts. And those suppliers are quote often the same ones as they are for the COTS stuff.

You have to wonder why many migrants in Europe go missing at sea on rickety barges on a regular basis and they call off a few search boats in 24 hours. 5 Billionaires go missing on a rickety sub and multiple nations respond with everything they have. Double standards much?

I think you can follow it all the way back to the taxpayer/voter honestly.

Ask people how long search crews should look for migrant boats, citing the cost, youll get some very mixed responses

Ask people how long search crews should look for a submersible containing a billionaire, his son and whoever else and it will be longer on average

In such a truly free world, you might have to check every piece of chicken for salmonella contamination. You might have to stop your truck at every turn to see if people are racing from the opposite direction. You might not be very sure that your alcohol is not actually methanol.... Regulations do make our life smooth, even if there is a tendency to go overboard.

The difference is scale and ability to measure risk. We know how to make chicken safe and a lot of people eat it, so regulation works well. For subs, it is a tiny number of people and risks are nearly impossible to assess.

> risks are nearly impossible to assess

this is total fabrication, we have submarines for 200 years. WW1 german u-boats were safer than this piece of crap

Stick drift would be really bad.

It's not a Nintendo controller.

Joycons arent anything compared to pre 2010 3rd party console controllers in terms of stick drift. I had ones that had button drift too

> Personally, I think it ought to be illegal to misrepresent your service’s safety Of course it is. But I think GP was just saying that there are no agencies to check rare venture like this. At least not before an incident happens.

I agree that there doesn’t currently seem to be regulations governing what OceanGate is doing. My point is that there should be some in the future so this kind of thing doesn’t keep happening. > But I think GP was just saying that there are no agencies to check rare venture like this. I think they were making a stronger claim: that there is not only no agency currently doing this, but that it is pointless and impossi…

It would of course be possible to regulate OceanGate out of business, and I sympathize with the desire to make sure people are sufficiently informed about the risks, which is hard.

But I agree with GP: there is something off about the calls for regulation here. Fundamentally, people should have the right to risk their lives in crazy expeditions to the bottom of the sea or the top of a mountain, and charging someone else money to be taken along does not change that.

The use of the controller is symptomatic of their attitude, but I agree that it's probably not as relevant as, say, using an untested (and apparently untestable) carbon fiber hull:

> Lochridge’s concerns mainly focused on the company’s decision to rely on sensitive acoustic monitoring – cracking or popping sounds made by the hull under pressure – to detect flaws, rather than a scan of the hull.

Lochridge said the company told him no equipment existed that could perform such a test on the 5in-thick (12.7cm-thick) carbon-fiber hull.

“This was problematic because this type of acoustic analysis would only show when a component is about to fail – often milliseconds before an implosion – and would not detect any existing flaws prior to putting pressure on to the hull,” Lochridge’s counterclaim said.

Theranos is an outright fraud. Not the product of getting things done on fast track. They knew things could not be done and kept up the charade for long enough to profit off of it, and hopefully get away.

Really? Think another way: MVP. MVP is a big in the startup scene. No startup tells you how they made there MVP. Most of them think, if I get enough investment, if I get enough customers, then I will make it better. But until now the other way is just enough for my MVP. So some would call it MVP and others would call it fraud. Until it is really being implemented as advertised.

V stands for viable.

> Theranos is an outright fraud. Not the product of getting things done on fast track Theranos is product of the same culture. Company founder chases a goal they do not understand, and convinces investors its right around the corner. In actuality they have no clue. There is no foundamental difference between theranos diagnosis and tesla autopilot. The only reason we call theranos fraud is that we know conclusively th…

> OceanGate Inc. is a privately held U.S. company operating out of Everett, Washington, that provides crewed submersibles for industry, research and exploration. The company was founded in 2009 by Stockton Rush.[1] Why do you blame Silicon Valley for that?

"Move fast, break things" is a SV mantra. That is ok for entertainment software or social networks but when you apply this to systems where people can die like healthcare, cars, spaceships and submersibles it's a problem,
