as much as I'm all for the freedom of knownledge, given the sorry state of the world, releasing these tools to imbecils is not peak foresight.. mcafee for linux next ha../s
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
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.
It seems the manufacturer of the camera didn't even know (at least in the part of the org communicating with the NTSB) that their storage was encrypted. In any case the media recovered were from testing/non-dive environments, and during an actual dive footage would presumably be recorded directly to the onboard computers (which were irrecoverably destroyed).
Oceangate should take the blame for a lot of things but probably not this.
I hope some day the tedious part of what you do, can be automated (AI?), so that you (or others) can spend their time on whatever aspect is most interesting. Vs all the grunt work needed to get to a point where you understand what you're looking at.
Btw. any 4 bit cpus/uC's in your collection? Back in the day I had a small databook (OKI, early '90s iirc) that had a bunch of those. These seem to have sort of disappeared (eg. never saw a pdf of that particular databook on sites like Bitsavers).
when the state if the nation is so bad that you have homeless everywhere, healthcare, housing and education are something you have to fight for, prisons are a business, suddenly another perspective seems more alluring, a modern Nordic socialism? putting a brake to unhinged late stage capitalism? or on the darker side, a promise of better conditions in 'some ways'...this is no national security risk, people are getting simply fed up with appalling state of the nation.
Interesting behaviour, usually any normal rope knot makes the rope weaker at the point of maximum curvature/choking etc. Would be enlightening to get a comparison why the different behaviours, just a scale/friction non linearities?
They claim the structure is tougher (absorbs more energy) not stronger (maximum force before breaks). As far as I see they say nothing about if it is stronger or weaker than straight lines. Likely because it is weaker due to the curvatures leading to stress peaks in the material before the ultimate force of two straight filaments was reached. They should have presented the force-displacement diagram too which is essential data (maybe the original article has it). I'd be curious seeing the force-displacement diagram of the two illustrated experiment compared to the diagram of two straight fibres tested.
Also I guess the toughness is just a relative matter to the dimensions of the structure but since uses much more material than two straigh fibres it is less tough by weight (due to the decreased strength). If the same amount of material was connecting the top and bottom with straight lines then that would lead to the toughest situation of all (absorbing the most energy). Again, guessing.
In the video the woven material may have tighter threads with stronger friction or more uneven friction distribution leading to reaching the yield limit of the filaments quicker. The woven with some 'lubrication' should have had similar properties assuming the same amount (length or weight) of material included. I'd also be curious then about the reproducibility of the results on the same kind of structure. Like if making the same knotted pattern would lead to the same results or slight deviation of geometry was affecting the end results significantly.
It looks like the loop of the knot permits slack which in turn causes stress on the fiber to be taken up by straining neighbouring weaves, rather than causing the stressed fiber to immediately strain to its failure point.
Unhinged capitalism will be the cause of the most devastating global crisis that is just around the corner. You can see it very easily on a simplex plot, you cannot solve for anything useful, like global quality of life, when there are parameters that have infinites, ie infinite 'growth' bullshit. It's a closed system, limited planet. We need to find a better metric, and forget about 'getting rich, work all your life' crap, when you are dead you take few cubic meters of space including ground, all your real estate 'investing' and stress, they just end 6ft under.
