asimovDev•1d ago
is this a common setup to have the camera store to external storage device without storing to the SD card as well?
malux85•1d ago
Yes because external storage is much larger, and theres nothing more annoying than being in the middle of doing some science with 30 other bits of complex equipment, and then the camera stops working with storage full errors and youre 7000m underwater in a cramped sub trying to navigate a camera UI to find the setting.

Configure your systems so they are in the configuration that is less likely to cause random disruption in the field.

3eb7988a1663•1h ago
Which makes me wonder why they bother with the SD card at all. What was it meant to be storing? If it is not intended to be the real storage area, why not just have it in a loop, constantly over-writing the oldest material?
aucisson_masque•53m ago
They probably used it for testing only, hence why it had irrelevant footage.

They might have forgot to remove or just didn't care.

intothemild•1d ago
It continues to amaze me how indestructible SDCards are.
imploded_sub•1d ago
It wasn't in the crushed part, it was in the camera's shell, and the camera was mounted outside, if I understood properly.
netsharc•1d ago
And:

> This still and video camera is rated to withstand depths up to 6,000m (19,685 feet, 3,281 fathoms)

Unlike the Titan sub...

3eb7988a1663•1h ago
The picture looks like the camera + storage SD card were in a sealed metal tube that was untouched.

Firefox on mobile supports uBlock Origin
firesteelrain•20m ago
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 Safari if you enable it under Safari

pajamasam•38m ago
Just use the Brave browser. No plugins necessary.
1oooqooq•1h ago
i was also in shock, then someone reminded me there are iphone users.

the horror.

paying thousands of dollars just to be forbidden to block ads.

haunter•51m ago
?

There are countless free and paid options on iOS too

Firefox Focus, Brave

AdGuard Pro, $9.99 once and you can use any blocklist you want (you can just copypaste from uBlock Origin if you wish) and it works system-wide with Safari

etc

jamiek88•27m ago
what? there are many fantastic ad blockers on ios. Weird thing to crow about.
pwg•1h ago
With UblockOrigin blocking the ads, there were no ads and pop-ups.

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.
amelius•2h ago
Why isn't a cellphone filled with epoxy?
bell-cot•2h ago
That would be a problem for the mic and speaker, and has relatively few use cases.
tom_alexander•1h ago
How would you do screen replacement? That is a common repair since people drop their phones and currently you can get your phone repaired by some teenager in a booth at the mall. If you fill the phone with epoxy, how are you detaching the screen, and getting a new ribbon cable through the epoxy?
throwaway173738•1h ago
use pogo pins or a board to board connector
bluGill•58m ago
Which means air space that can get crushed. Either the phone is solid or it isn't.
JumpCrisscross•25m ago
> Which means air space that can get crushed

Would note that air isn't the only substance in a phone that compresses under 38 MPa. (Batteries come to mind.)

userbinator•1h ago
I'm sure there are some companies who want to do that, as long as they can convince people it's better for security or something.
numpad0•1h ago
It's just not necessary, while having reliability problems of its own.
dotancohen•1h ago

  > Why isn't a cellphone filled with epoxy?
Added cost and weight are two things that would put off consumers. The phone would also be neigh irreparable, but consumers don't seem to care for that other than replacing their screen.
amelius•1h ago
A conformal coating wouldn't give much more weight.
dotancohen•1h ago
A conformal coating isn't "filled with epoxy", which is the concern I was answering.
amelius•1h ago
There is very little empty space in a phone, so conformal coating is practically the same as filling it.

Anyway, I wasn't disagreeing, just reasoning a bit further.

cjbgkagh•48m ago
The point of filling it is to remove the compressible empty space so that large pressure gradients won’t crush it.
estimator7292•23m ago
No, conformal coating and potting are extremely different things done for different reasons.

jjk166•1h ago
When was the last time your phone stopped working due mechanical PCB damage?

Typically the limiting factor on your phone is the screen breaking, your battery life getting too short, wear and tear on components like buttons or the charging port, and factory defects. Epoxy isn't going to help with any of those. The only thing it would help with is exposure to water, but if other parts of your phone like your screen aren't water proof, what's the point?

Epoxy adds weight and manufacturing cost. It introduces design challenges as you need to balance the thermal expansion of the various parts. It's an extra step that can go wrong, and makes repair of other defects far more difficult. What benefit is there for the typical consumer that outweighs these costs?

0_____0•41m ago
The GoPro Session actually took this tack to achieve waterproofness without a secondary case.
scrumper•14m ago
Well, most cellphones aren't subjected to the conditions found under three miles of frigid sea water. Epoxy is also really, really expensive.
Towaway69•12m ago
Thermal concerns perhaps - how does epoxy dissipate heat?
pfdietz•30m ago
This comment made me wonder how much easier proximity fuzes would have been to develop in WW2 had they had transistors (or integrated circuits). I assume making modern solid state electronics 20,000g shock resistant is much easier than doing the same to vacuum tubes.
MadnessASAP•10m ago
No need to wonder, proximity fuzes are still used today. And yes, they are much smaller, cheaper, more reliable, and precise.
dylan604•19m ago
So that's the next phase of making devices thinner? /s

The SDCard that was in another sub, properly constructed from titanium not carbon. The sub housed a camera, no humans.
userbinator•1h ago
Heat and wear are the greatest dangers to flash memory, and this was found in a cold dark place, with presumably plenty of life remaining.
reaperducer•1h ago
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.

Gigachad•1h ago
Put one in a Raspberry pi and it will be dead in a month.
jonas21•1h ago
The NTSB's original report has more detail on how the SD Card was encrypted and how the NTSB managed to decrypt it:

jeffrallen•59m ago
Does not leave SubC in a particularly flattering light...
Hamuko•1h ago
But how did anyone figure out it was a SanDisk SD card? Card details were redacted.
Macha•1h ago
There's only 3 manufacturers of SD cards in any volume, you can compare the branding and font choices and see who's it is.
serf•1h ago
SanDisk is one of the big three on SD-3C/SD Association.. so kinda regardless of the MFG it's 'one of theirs' in a roundabout way.
matja•1h ago
Presumably because it looks identical to a Sandisk extreme pro 512gb, with grey boxes drawn over the logo.
siliconunit•1h ago
also basically if enough companies agrees on helping the cause your crypto secrets are quite more likely to be exposed...
yread•1h ago
Isnt the weakness here that there was nothing encrypting the actual key? On a laptop luks key stored in a tpm would usually be encrypted using your passphrase
XorNot•47m ago
The NTSB report noted that if the TrustZone secure enclave system was being used, then yeah this data would be toast.

But it speaks more to Oceangstrs negligence that this situation even existed: why wasn't any potential encryption keys escrowed ashore to ensure they could be recovered later? This shouldn't have even been an issue.

dmix•54m ago
Since not everyone reads articles:

> Somewhat disappointingly, the images and videos shared in the report were taken in the vicinity of the ROV shop at the Marine Institute, also in Newfoundland. The location was the logistical base for Titanic dive missions. No deep-sea shenanigans around the Titanic wreck were revealed.

RandomBK•48m ago
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 ARM TrustZone NVRAM of a chip.

3. The recovery was done by transplanting the original chip onto a new working board. No manufacturer backdoors or other hidden mechanisms were used.

4. Interestingly, the camera vendor didn't seem to realize there was any encryption at all.

nxobject•35m ago
If the encryption was that easy to bypass, was it worth it at all?
anakaine•4m ago
Sure. If the card was recovered without the camera motherboard then the decryption key would not have been recovered.
Keeblo•25m ago
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.
