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…

Alot. Just google cameras for deep sea and space. Several companies make these and despite all the covering up, none of the tech is that special.

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.

Lol, and the censored controller is a teensy 3.2

It's a solid piece of silicon encased in epoxy, so there's nothing really to get crushed. Contrast this to something like a cellphone that's made of hundreds of separate parts and has void space that will get crushed.

So were the flash chips on the SSDs they found. It didn’t save them.

the plural part is the key here, the bigger area means any uneven forces have more chance of bending and cracking stuff.

It was also in casing already prepared for that type of environment

Unless I misread the article, the key was stored in the NVRAM and not the TrustZone. IIRC, the article stated that if the key(s) had been stored in the TrustZone then the data would have been irrecoverable.

Firefox on mobile supports uBlock Origin

On iOS, every browser is required by Apple to use WebKit. I just tried it again myself and FireFox on iPhone has no ublock Origin add on possibility. Firefox Focus does work as an alternative. Apple created a special system-level API for Safari Content Blockers. Apps like Firefox Focus, AdGuard, 1Blocker, Wipr can register filtering rules with Safari using this API. That’s why Focus can block ads/trackers inside Safa…

Didn’t this change recently?

Can I ask why? I'm not really into microprocessors.

Usually (not always), something like a Teensy or a Pi Pico or an Arduino is treated like a development board for prototyping. A person builds out their circuit using hardware they can solder/wire-up by hand on a workbench, maybe even with relatively-giant solderless breadboards, to prove the concept and the general design. And a dev board can be great for spinning a few prototypes. It's quick to get started (code can…

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 subm…

Just fyi - if your car has been manufactured in the last 10 years by a modern corporation(ie - not a Lada) it will have a black box already that records everything about the car's systems. They don't record sound from the cabin, but your speed, throttle position, movement of the steering wheel - it's all recorded.

In my country, people call dashcams "black boxes". They can be quite useful if you also want audio and video.

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.

> There is something slightly romantic…

if he was alone i would absolutely agree with you full stop.

but it looks like they may have been entirely underselling just how backyard amateur their company was just to get people to give them money.

i totally adore books and documentaries and tales of explorer types pushing their ideas to the limit but it quickly crosses a line when they:

a) downplay dangers to innocent people, and

b) refuse to understand their own ignorance and believe the people who have already literally done their idea are somehow “fools”

the person who is trying to “disrupt” but doesn’t have a deep understanding of the often very good reasons why an industry may do things a certain way is the fool. not the ones who already repeatedly make it work.

we need to encourage adventurousness but also wisdom.

Clickbait? Where? How? It's literally in the NTSB report, and it's not like, a crazy concept?

I mean I have them in both of my cars, but in some places like Austria it's straight up illegal to have them in your car. And in some others like Germany you can have it but the footage is inadmissable in court because the other person never agreed to be recorded. The built in telemetry recording is legal everywhere though.
