Earlier quoted context omitted.

They had no idea how their own product worked. They didn’t even know it used encrypted storage. This was either outsourced or done by some junior engineer who was putting pieces together like it was another Raspberry Pi project that just needed to kind of work.

The longer I last in this world the more products I realize are the result of telling a few people who don't know what they are doing to "make it kind of work."

This is in fact the case.

I see a lot of discussion in this thread stemming from some confusion+not reading the actual report[0]. Some key points: 1. The Camera+Card was encased in a separate enclosure made of titanium+sapphire, and did not seem to be exposed to extreme pressures. 2. The encryption was done via a variant of LUKS/dm-crypt, with the key stored on the NVRAM of a chip (Edited; not in TrustZone). 3. The recovery was done by transp…

0. They were too cheap to use an industrial grade SD. Mind boggling.

If you read the article, the SD card was placed there by the camera manufacturer and then the device was sealed so it would withstand pressure, and then sold to divers. Blame the camera manufacturer's engineers.

Seems like the SD card of all things performed just fine, so it hardly seems like the weak point.

It continues to amaze me how indestructible SDCards are. Until they're sold as supplemental hard drives ( cough Transcend Jetdrive cough ). Then they'll fail if you even look at them strangely.

Put one in a Raspberry pi and it will be dead in a month.

remember the noatime mount option for the root fs!

If a hardened camera can survive, I'm surprised subs don't have a floating black box that can survive an implosion and then float to the surface and begin emitting a radio signal. I guess the trick would be finding a way to securely attach the black box in a way that would ensure its release in a catastrophic disaster.

The ones that aren’t accompanied by a surface ship are military, and they really don’t want anything that might automatically deploy at the wrong moment.

Figure 3 from the report- that's an Adafruit sensor module on a 3d printed bit of plastic with a teensy-brand microcontroller just sitting in there! Actually, the entire electronics enclosure appears printed. Very funny to see in what I assume is a million-dollar product.

What was the water condensation situation like in this submarine? Semi bare electronics sounds very very bad.

Any money spent coating those semi-bare electronics would have been wasted. There's an engineering lesson to be taught here, I'm sure.

On-brand, though. And speak some respect to Adafruit's name! Lady Ada's product isn't what failed.

There are a zillion applications for black-boxes, so why not start somewhere more accessible and with more impact? Your own house, car, and person, for instance. Think of how many elderly people die at home and nobody knows the details leading up to it. I'm being a bit facetious here - perhaps we don't need to know in those cases, nor in the Titan case. It's not as if there could be any data there which advances submarine safety - unless somebody is planning to build a Titan v2 with the same technology, marginally improved safety, and similar lack of testing?

I guess he wasn’t planning for a catastrophic failure ?

He ridiculed anyone who told him he should, taking it as evidence that he was disrupting an industry. There is something slightly romantic about dying in such a way that his body turned to mist and floated away in the current. A bit like having your ashes spread at sea. With fewer steps.

I keep thinking about the teenager.

Who didn't want to go and didn't feel safe, but who was pushed to come along by his father because it was his father's birthday.

I haven’t bothered working out how to install one on mobile. I just don’t visit websites with shitty ads.

Just use the Brave browser. No plugins necessary.

It has poor compatibility on the iOS version that I've got installed, sadly.

This was part of what complicated the response to the Kursk disaster - they had a rescue buoy but it was welded in place so it couldn't deploy.
