Car companies could sell midrange, mid-size cars, toyota sells these in pretty much every country on the planet, but they're nowhere as profitable as selling a $12,000 truck with a lift kit and leather interior for $55,000. Those vehicles exist but they've stopped selling them in the us because theyve found they can just exclusively sell high margin cars instead and maximize shareholder value

We are only a year out from the murder of a health-insurance executive, so the police are more on edge than usual.

Then we need to threaten such things much more often, so that the cops will eventually get used to it, and relax. ;-)

Debian never tried to kill me through my computer. I'd appreciate it if my car manufacturer made their car as safe as my computer.

Fuck it, I just want a Debian car. Then I won't need to extract bloody vengeance from beyond the grave, as my zombie revenant tracks down the CEO of Subaru, and the rotting flesh of my hands tightens around his throat as payment for the time a popup distracted me.

Comment There's no consensus definition of E2E encryption (Score 1) 89

Some people are busting out "definitions" of "End to End Encryption" but people were already using that as in informal descriptive term long before your formalized technical jargon was made up. Nobody should be surprised if there are mismatches. Have faith in our faithlessness.

I personally view the term as an attempt to call semi-bullshit on SMTP and IMAP over SSL/TLS. In the "old" (though not very old) days, if you sent a plaintext email (no PGP!), some people would say "oh, it's encrypted anyway, because the connection is encrypted between your workstation and the SMTP server, the connection from there to some SMTP relay is encrypted, the connection from there to the final SMTP server is encrypted, and the recipient's connection to the IMAP server is encrypted."

To which plenty of people, like me, complained "But it's still plaintext at every stop where it's stored along the way! You should use PGP, because then, regardless of the connection security, or lack of security on all the connections, it is encrypted end to end. Never trust the network, baby!"

Keep in mind that even when I say that, this is without any regard for key security! When I say E2E encrypted, it is implied that the key exchange may have been done poorly/incorrectly, mainly because few people really get to be sure they're not being MitMed when they use PGP. You can exchange keys correctly, but it's enough of a PITA that, in the wild, you rarely get to. You usually just look up their key on some keyserver and hope for the best. Ahem. And I say "usually" as if even that happens often. [eyeroll]

Indeed, every time I hear about some new secure messaging app/protocol, the first thing I wonder is "how do they do key exchange?" and I'm generally mistrusting of it, by default. And sometimes, I'm unpleasantly unsurprised, err I mean, cynically confirmed.

But anyway, if my E2E definition matches yours, great! And if it doesn't, well, that's ok and it's why we descend into the dorky details, so that we can be sure we're both talking about the same thing.

Remember that models used from a decade or more ago always make simplifying assumptions, and that those tend to be unquestioned until data shows that they must be. Even now climate models can't handle all the variables known to be needed. Turbulence is *extremely* difficult to handle. And there probably is some "butterfly effect". The way that's normally handled it to run an ensemble of models with slightly different conditions, but they may all make some of the same simplifying assumptions.

Well, panspermia is possible, but not extremely likely. OTOH, if life started on Mars, it could well have spread to Earth on impact debris. The further away, the less likely. But remember that yeast have survived in space conditions for months, perhaps years...and that wasn't in extreme cold (though it was in inactive form).

OTOH, years is different from centuries. And for interstellar trips in a comet, centuries wouldn't be enough.

Those are descendants of LUCA. A better question would be viruses, because in that case we don't really know. (There aren't any ribosomes. [OTOH, if there are descendants of another origin, they've massively adapted.])

OTOH, we haven't checked all life on earth. So assertions about universals should be viewed with that in mind.

No. The mapping of nucleotide sequences onto amino acids isn't predetermined. We've built in the labs versions that are different.

OTOH, the argument still isn't good. It could be a low, but not extremely low, probability. In that case the first one to show up could have a VERY strong advantage. And we haven't checked all life on Earth, so the assertion that they are all the same hasn't really been proven, either.

We are pretty certain that the appearance of life involved some very low probability events, but that there were a lot of environments around with lots of different samples for a long period of time, so a "low probability event" should be expected to show up (even if not any particular low probability event).

Different groups of people designate street crossings and manage school buses. Ideally you're right, it should be fixed. Now get two different groups of people with different priorities to agree.

If you don't like the rule, manage it with school bus routing, but prepare to need twice as many route miles along lots of segments.

AI Chatbots Can Sway Voters Better Than Political Ads (technologyreview.com) 67

An anonymous reader quotes a report from MIT Technology Review: New research reveals that AI chatbots can shift voters' opinions in a single conversation -- and they're surprisingly good at it. A multi-university team of researchers has found that chatting with a politically biased AI model was more effective than political advertisements at nudging both Democrats and Republicans to support presidential candidates of the opposing party. The chatbots swayed opinions by citing facts and evidence, but they were not always accurate -- in fact, the researchers found, the most persuasive models said the most untrue things. The findings, detailed in a pair of studies published in the journals Nature and Science, are the latest in an emerging body of research demonstrating the persuasive power of LLMs. They raise profound questions about how generative AI could reshape elections.

For context for those not familiar with experimental/homebuilt aircraft. You can pretty much use anything off the shelf or custom. 3D printed parts (either self-sourced or purchased from dedicated vendors) are probably not uncommon at this point in time, depending on what you are using them for. Certified aircraft do not have this degree of latitude in terms of part sourcing and DIY work.

Now to the question about whether the owner made/installed the part, or it was sourced through the parts chain:

https://www.bbc.com/news/artic...

"The Cozy Mk IV light aircraft was destroyed after its plastic air induction elbow, bought at an air show in North America, collapsed."

That sentence implies that the air induction elbow was purchased at an air show.

Reviewing the accident report ( https://www.gov.uk/aaib-report... ), we get the following:

"The aircraft owner who installed the modified fuel system stated that the 3D-printed induction elbow was purchased in the USA at an airshow, and he understood from the vendor that it was printed from CF-ABS (carbon fibre â" acrylonitrile butadiene styrene) filament material, with a glass transition temperature3 of 105ÂC.

An alternative construction method for the air induction elbow, shown in the Cozy Mk IV plans, is a lamination of four layers of bi-directional glassfibre cloth with epoxy resin. The epoxy resin specified for the laminate has a glass transition temperature of 84ÂC, after the finished part has been post-cured. The aircraft owner stated that as the glass transition temperature listed for the CF-ABS material was higher than the epoxy resin, he was satisfied the component was fit for use in this application when it was installed.

A review of the design of the laminated induction elbow in the Cozy Mk IV plans showed that it featured a section of thin-walled aluminium tube at the inlet end of the elbow, where the air filter is attached. The aluminium tube provides a degree of temperature-insensitive structural support for the inlet end of the elbow. The 3D-printed induction elbow on G-BYLZ did not include a similar section of aluminium tube at the inlet end."

So apparently purchased through a 3rd party vendor, the owner installed according to an existing design variation (and got approval from regulatory oversight to do so), but apparently the 3d printed part installed did not meet the requirements for temperature resistance as compared to the glass-fiber/epoxy part specified in the plans, possibly due to the lack of that aluminum tube.
