However, I think there is a real possibility that the Signal code (of which the public appstore versions are NOT fully open-source) could be modified to save/transfer messages after they have been decrypted, basically circumventing the whole point of e2ee... which is why having control over the client code is essential.
I suggest either building Signal yourself, using only verified reproducible builds without any binary blobs, or switching to the Molly-FOSS fork.
It's not clear. The relevant text seems to imply that an attacker can link their own device to a target account via providing a malicious URL (vs. commandeering an already-legitimately-linked device, which I guess is what you're imagining). That sounds like a legitimate flaw. But there are no details.
No, bypass means to go around, not to break. So this is correct terminology. By adding devices into a chat, you get to see the plaintext messages, thus bypassing the protection provided by the end to end encryption.
Not impossible but much harder than working closely with humble and experienced engineers. That's why I recommend that a junior engineer finds a great consulting company as soon as they can and spend a few years there. This was a kinda breakthrough period in my career for both technical and soft skills. The nature of consulting also means that you might see a greater variety of environments, technologies, and problem/solution combinations than the equivalent xp in a non-consulting role. But make no mistake, finding a "good" consulting company is key. You need to have humble and experienced engineers who want to help you and grow you. If it's a "bums in seats" kinda "body shop" or some kind of celebrity house for "hero" or "10x devs" then maybe this won't be as useful.
Seriously, a YouTube video is supposed to be proof that batteries last ages? What is ages? If you provide something I can read you might have been able to change my mind.
Truth is not many want to risk buying a used electric car and the depreciation reflects that.
Generally, 10-20 years and 100K-200K miles. The US requires a warranty of 8 years and 100K miles.
For newer cars it's hard to tell for sure since the tech has improved significantly in recent years. But even the earlier cars have done better than people expected.
A quick google turns up lots of sources you can read. Here are a few:
you just need to know the SoH (state of health). If that's 90% then you've lost 10% of the range at new. The lower the SoH for the same vehicle make, model, year and driven kms, then the worse the car has been treated. Simple as that.
I don't understand where this thinking comes from. It's not based in fact. These Tesla batteries degrade very slowly. And so if in 5 years you've lost 15% of the range, it still gets you anywhere you need to go including road trips with all of the Superchargers!? "totals the vehicle" is just nonsense and I wish more people understood the reality.
> I don't understand where this thinking comes from.
My observations, which certainly don't reflect the current state of the tech (although if I'm buying a used EV, I'm not buying the current tech). But that's my bias nonetheless. I do think I overemphasized this, though, because while this is what makes me shy away from the idea of used EVs, it's not the reason why I avoid buying cars that are too new (which includes pretty much all EVs).
Since Tesla funds Dahn's research, they get the IP. This is just in the lab but those advancements are trickling, over time, to Tesla's battery making (and not just Tesla: every battery maker does research to make batteries cheaper and last longer).
Supposedly, first-gen Leafs were known to have pretty nasty degradation due to lack of sufficient cooling. Combined with an already short-range battery, and the belief that you'd need to replace the battery frequently was justified.
Key word: WAS
Of course, modern EVs, and basically all Teslas, have bigger batteries with better cooling, so it's no longer an issue. But the belief won't die, just like how people still make memes about Java being slow as if it's still 1998.
