Yeah, you’re right, you can open up a black box in a way you can’t really for a typical phone app/OS stackup. Maybe I argue it’s no longer a black box then, but no matter. I had originally started in on another section about better permissions and data handling and such, so I probably had a more optimistic view of permissions in general when writing, but one of the points was about being able to sniff your own (app’s) packets to be able to monitor what’s collected and sent at any given moment. That’s the sort of thing that I think makes the most sense, to directly interrogate the issue of what data they are sending back about you, rather than making logical connections from other observations.

Counterpoint: It might be normal for that device to have a WiFi radio or something to communicate wirelessly, but if the software is actually using the antenna to detect and track your heart rate, it might require an extremely (or even impossibly) talented hardware engineer to notice anything fishy from the device’s hardware itself. The WiFi and heart-rate thing specifically might not be a viable vector, dunno, but it can be a lot harder to check for stuff than just seeing if there’s an “ACME Spy Microphone” module plugged into the board somewhere. Though I agree they would probably get a worse reaction from illicitly including a hardware feature vs an app scraping the same data from your phone, even if they’d send back the same info; also that you could at least know a separate device was only tracking your car’s location, and only when you brought it with, not relying on it’s own software to decide when and where to collect data.

Ultimately, the solution might have to involve not using an OS developed by a company that also wants to slop up as much data as it can, but only so much one can do. At the very least, it’d be nice to get more separation between a “personal space” that you live your life in, e.g. socialize and consume content, and a “functional space” for other stuff that will run on your phone or you access occasionally but isn’t part of you being you, like apps for random companies or services, phone lights/sensors, a driver-insurance-safety app that should just get data pipes in from a specific list of sources and isn’t supposed to be sending data home 24/7, etc.

In some ways I agree, but on the other hand, a “box with GPS, accelerometer, mobile data, and everything else it needs to function … built right in” is just a phone, minus a touchscreen and some extra computing power. And unless you know the hardware inside the black box, just blindly passing its data through could be even worse than an app pulling stuff off your phone.

Not seeing the relevance of need at all? It seems like a legit answer to the question, at least inasmuch as any specific content or documents can be, as opposed to forbidden knowledge/ideas like crypto key numbers or (in the past) the concept of a gun-type fission bomb.

Similar, but my real question is why you have an explainer for the North American Fiber-Seeking Backhoe but with a picture of a Northern Pipe-Cracking Excavator?

Is there actually something behind all these comments about his appearance, or is it just typical internet name-calling that mostly falls into the same anti-LGBTQ+ bucket?

I think that mental model only works if you imagine the parabolas as reaching to infinity in a finite space so that both ends are parallel, ie having identical vertical slopes of +/- infinity. At that point, easier just to call it “half an ellipse”. To me, it’s much easier to imagine a parabola as the end of an infinitely long ellipse.

Your intuition and the KSP example are correct though. If you imagine the plane and cone for a parabola, you wouldn’t notice any significant change to the shape (at a finite distance) if you tipped the plane ever so slightly into forming an ellipse (or a hyperbola, for that matter) since it’s all smooth changes.

Anyway, the size of the elliptical (I think hyperbolic would have a different sort of energy state) arc that’d be formed by a thrown object would be so large relative to human scale as to basically be infinite, equivalent to a parabola. I imagine the difference might become significant once you are launching something a decent way around the Earth, but with that much energy in play I don’t think it makes much difference where exactly the projectile “lands”.

“Till” is completely valid synonym of until. “'Til” is an informal contraction (and was probably meant to be the actual word “till”). If you’re gonna be aggressively prescriptive, at least pick an actual battlefield instead of attacking innocent folks.
