Huh. Apparently we justed needed to start a new platform to start dropping the real life pro tips. Seriously, where have you guys been keeping these??!?

I don’t know a single person who consumes milk because they think they require it. They just like the taste of dairy products.

The subsidization is an issue imo, but I don’t think people are as brainwashed regarding milk as you assume.

Nah thats bullshit. And this is coming from somebody who would tend to agree with you, but you can’t always be so excruciatingly black and white. For example, my dream job is what I do in my free time, except in a non-profit organisation where I am not chained by an individual lack of resources. Some work furthers humanity. Some work is completely voluntary. Sometimes a dream job is that way to scratch the biological itch to keep our brains busy.

Additionally, this supports the bullshit capitalist argument that people wouldnt want to work anymore if not coerced into it. I believe people would still dream of doing important jobs that help humanity even out of their own free will.

Who wouldn’t? They are doing some of the most advanced rocket science on the planet. Of course, trusting corporations statements and research is an entire topic of it’s own. Taking Elon Musk seriously on the other hand…

TMR (so the tripilicate method) wouldn’t be super suitable for this kind of application since it is a bit overkill in terms of redundancy. Just from an information theory perspective, you should only have enough parity suitable for the amount of corruption you are expecting (in this case, not a lot, maybe a handful of bits after a year or two). TMR is optimal for when you are expecting the whole result to be wrong or right, not just corrupted. ECC and periodic scrubbing should be suitable for this. That is what is done by space-grade processors and RAM.

It should be fine for normal use cases when used with error correcting codes without any active scrubbing.

According error rates for ECC RAM (which should be at least by an order of magnitude comparable) of 1 bit error per gigabyte of RAM per 1.8 hours1, we would assume ~5000 errors in a year. The average likelyhood of hitting an already affected byte is approx. (5000/2)/1e9=2e-6. So that probability * 5000 errors is about a 1.2 percent chance that two errors occur in one byte after a year. It grows exponentially once you start going a past a year. But in total, I would say that standard error correcting codes should be sufficient to catch all errors, even if in hibernation for a whole year.

The gold around satellites are actually very thin layers of mylar, aluminum foil and kapton (a type of golden, transparent plastic) which are used to keep heat inside the satellite inside, and heat outside, outside (See Multi-Layer Insulation). Radiation shielding usually comes from the aluminum structural elements of the spacecraft, or is close to the electronics so you do not waste too much mass on shielding material. Basically, shielding efficacy is most determined by its thickness, so it quickly becomes quite heavy.

And when someone says “dream job” they are referring to the semantically correct meaning of the word? I have my doubts. When people say they’re dream job consists of doing something, like “helping people”, I think it is the “work” that interests them, and not the financial details.

What you call sick is only sick if you take your awfully correct definition, which I honestly don’t think correlates well with what people mean with it.

Thats also why I would still tend to agree with you, because I dont believe in laboring for some bosses benefit either. But certainly not with the initial wording
