<p>Anyone who’s worked inside the sortation centers has also seen sorters crash and rip packages to shreds.<p>Obviously that’s not “normal” damage to packages, because those things certainly aren’t getting delivered, but it’s not like these things get handled gently by the automation. Packages slide into collection belts where they land hard on top of other packages, they zip down chutes to be loaded into semis, etc.<p>There’s a reason they want breakables properly packed, and it’s not because the last-mile delivery guy is going to shoot a three with your box.</p>

<p>Subjectivity is implied. You’re shadowboxing against a claim that the person you replied to never made. Communication is more than the simple dictionary definitions of the words being written.<p>And as has been pointed out, you are yourself asserting your opinion about subjective communications as fact (i.e. that you should always make it denotatively clear to readers when you’re going your opinion and when you’re globally asserting something)</p>

<p>My understanding was that each satellite broadcasts a coarse ephemeris for the whole network, and that that “almanac” isn’t accurate for very long (on the order of weeks). Without uploads to the satellites, those almanacs will go stale.<p>I don’t think the almanacs are necessary for the system to work, in theory. But I believe they’re commonly used by receivers to narrow down the range of possibilities when trying to find a PRN match for a signal they’re getting.<p>(I’ve dealt with GPS and similar navigation signals for work but am not an expert, this is just the impression I’ve gotten over a few years)</p>

<p>This is a great plot for a B movie or a trashy military action book. “The bad guys are jamming GPS uplink and we only have two weeks until the almanacs are out of date and the whole system breaks down. Millions of innocent Americans will drive into rivers by accident.”</p>

<p>The way NASA did it for decades was conference calls. Nowadays it's Teams meetings.<p>The outputs of the meetings are decisions that are later encoded in very many very long documents. It's just faster to hash out engineering details when the relevant engineers are able to talk to each other in real time and relevant decision makers are present to be able to unofficially bless or reject what the engineers come up with (formal acceptance of these decisions is of course a paperwork thing).<p>So, in this domain anyway, it's not a literal phone call. But it's what we see as the modern equivalent.</p>

<p>Perhaps. Sometimes the scale is "one" - the amount of engineering that goes into bespoke space missions is very large, and very little of that work is re-used for anything other than direct follow up missions</p>

<p>Even then... the reason we use the aero toolbox is because everybody in the aero industry trusts that MATLAB's results are accurate. I don't need to prove that the ECEF<->Keplerian conversions are correct, I can just show that I'm using the toolbox function and people assume it's correct. The aero toolbox is trusted.<p>When I've had to write similar code in Python, it's a massive pain to "prove" that my conversation code is correct. Often I've resorted to using MATLAB's trusted functions to generate "truth" data and then feeding that to Python to verify it gets the same results.<p>Obviously this is more work than just using the premade stuff that comes with the toolbox.<p>Any MATLAB alternative faces the same trust issue. Until it reaches enough mindshare that people assume that it's too popular to have incorrect math (which might not be a good assumption but it is one that people make about MATLAB) then it doesn't actually mimic the main benefit of MATLAB which is that I don't need to check its work.</p>

<p>I can attest to that. I was using Gemini to help with some spherical geometry that I just couldn't figure out myself. This was for an engineering system to define and avoid attitude deadzones for a system that can rotate arbitrarily.<p>About 75% of the time the code snippets it provided did what it said they did. But the other 25% was killer. Luckily I made a visualization system and was able to see when it made mistakes, but I think if I had tried to vibe code this months ago I'd still be trying.<p>(These were things like "how can I detect if an arbitrary small circle arc on a unit sphere intersects a circle of arbitrary size projected onto the surface of the unit sphere". With the right MATLAB setup this was easy to visualize and check; but I'm quite convinced it would have taken me a lot longer to understand the geometry and come up with the equations myself than it actually took me to complete the tool)</p>

<p>As someone totally uninformed, are you saying that all those YouTube ads about e.g. Private Internet Access (et al), which <i>specifically cite getting around geo restrictions in the ad copy</i>, are BS?<p>Which sounds like a silly question ("of course the marketing is BS") but why even bother marketing if the core value proposition of your billed-monthly service doesn't work? Seems like a waste of money since you'll at most get people for one month when they cancel after realizing they can't watch Canadian Netflix from Florida, or whatever.</p>

<p>They are either thinking of Vladimir Komarov (who died during Soyuz 1, in 1967 - six years after Gagarin's orbit, for whom Gagarin was the backup crew) or referencing the conspiracy theory that the Soviets tried a couple times to orbit a human, covered up initial failures, and only made Gagarin's success public because it worked.<p>Afaik there's not any evidence of this. The Soviets did have a bent towards secrecy so it's plausible, I guess, but it's definitely more the realm of creepypasta ("there could be dozens of old Soviet capsules in orbit with corpses inside!") than historical fact.</p>

<p>My employer (a small space services company) also had issues with our .space TLD. For a while every email from everyone at the company to anyone external was getting caught in their spam filters.

<p>I think your final sentence would be a more specific/more correct to say "five acres away", but in reality I don't think I've ever heard anyone use a furlong as a serious unit in conversation.<p>I have heard sentences like "the property line is two acres into the woods" and it was understood that he was using acre like you might use "block" in a city - "the property line is two acre widths into the woods". As you say, that's just a furlong, but I doubt either of us knew that at the time.</p>

<p>I must be misunderstanding because that seems like the most common morality basis in the world. People who equate running over a squirrel in the road to vehicular manslaughter (as if you had hit a human child) are seen as extremists, and someone who was OK with hunting deer as well as humans would be seen as having some sort of mental condition. The majority view is that species matters</p>
