That's a good world model until it's not. There was an HN article on this some months ago, I can't remember what keywords the title used to find it again though

#33Does this have any effect on the human body? Is this exposure measurably damaging for people?
As long as you're not in space you should be fine. If you are on the ISS, then you have some other experts you can consult, us randos on HN won't be able to help you much.
I would not be surprised if some space folk frequent this site.

Is a UTC day a different length to a common solar day? At this level of pre soon leap seconds and even sidereal day difference makes no difference
Yes, but they probably mean "the next 72 hours from right now given in UTC".
Or maybe they mean "day" as starting from UTC midnight.

H've never hAd any issues wiphout ECC.
That you know about... ;-)
For a couple years I had a process running on a PC without ECC that simply filled a large buffer with a bit pattern that was 50% ones and 50% zeros, and then periodically scanned the buffer for changes. It never found a changed bit.
I used a 2008 Mac Pro at work and a 2009 Mac Pro at home for several years. They had ECC memory. I would periodically check the RAM status and I never saw anything that said an error had been corrected.
For that test with the big buffer I don't remember how big a buffer I used, but I remember my calculations based on the error rate data I could find said that with the size buffer I was using I should have seen a few errors per year.
But I think all the error rate data I found was from servers with a lot of RAM and located in data centers. I wonder if that environment is more prone to RAM errors than the environment of the typical home computer?

#38Track the impacts on https://www.spaceweather.com/
Holy cow that's an insane website design. So, where exactly do I see the tracking? Is it below the grift of a 3D printed moon? Is it near the ads for casinos. Or maybe the mood rings? This isn't a bitch about ads. It's I honestly cannot easily find the actual information the site is supposedly hosting.
That site design is awesome. That level of information density is exactly what makes a good site. The information is right in the front, ads are off to the side. It's basically like a newspaper. Which is great for information.

#39Does this have any effect on the human body? Is this exposure measurably damaging for people?
Yes but you have to be an astronout in the outer space without enough added protection for the increase of radiation. Or maybe some increased exposure for high altitude flights near the poles. Other than that earth's atmosphere would make it that not enough exposure will reach the surface of the earth. Well things would be different for indirect harm because of satellite and signal failures. They could even cause dis…
It's my understanding that a Carrington event would destroy the bulk of the electrical grid on the side of earth facing the sun at the time. But would be pleased to hear how I'm wrong!

#40> The solar flare emanated from the sunspot group AR3842, which has made headlines before. On Oct. 1, the same sunspot region fired off a powerful X7.1 solar flare and unleashed a coronal mass ejection (CME) — a plume of plasma and magnetic field — which is currently barreling toward Earth. That incoming CME is expected to hit Earth between Oct. 3 and Oct. 5, possibly triggering widespread auroras.
I actually just saw an aurora for the first time in my life a few months ago in Oregon, where they're hardly ever visible. It was quite a sight. Maybe I'll get to see them again.
