totm nov 2023 SpaceX Discussion Thread
darthgently replied to Skylon's topic in Science & Spaceflight
That would be a very large, and massive pallet. If the sun were directly overhead one could easily get a momentary nice eclipse effect with boat positioned directly underneath it. -

As I recall, the owner, in this case SpaceX, has to have given up trying to salvage, or been forced by authorities to do so because they are failing to prevent the object from becoming a hazard to navigation in a timely manner or some such language -

darthgently replied to Skylon's topic in Science & Spaceflight
This rings a bell. I can't remember whether I read it as an idea or as a fact though. As has been noted, if a pallet with $60M cash were parachuting down into the ocean, shouldn't one try to retrieve it? So yeah, SpaceX would be motivated to offer a bounty -

Wouldn't the fairing have come down in an exclusion zone? Hope the guy didn't get in trouble as he didn't cause any and probably wasn't trying to steal the fairing or pull an injury claim by trying to get it to land on his head or something -

I've not had a problem finding the launches on YouTube after the fact from one channel or another and rarely do the launches line up with my schedule to watch them live anyway. That said, the X video player has improved quite a bit. YouTube's watch later queue is probably 60% of the reason I end up on YouTube with range of content being the other 40%. -

Midget? Not for a Kerbal. Age does not matter either. Get your facts right -
Thus the "lie flat" movement among the younger crowd in the PRC where they just don't give a shoot about anything anymore. More and more I think nihilism may be the great filter the alien civilizations we aren't seeing among the stars may have failed to pass through. Maybe it is a kind of nasty civilizational quicksand that commonly emerges eventually with sentience. They all gave up

Off-world data backup? Honestly, I'm more of a colonize space guy than a colonize Mars guy. I would like to see modified terrestrial life, even lichens, get a grip on Mars, because i do think it important to spread life. If Mars can sustain even microbes, we should make it so. But given the vast resources available out there I do think orbitals with spin gravity will end up being far more practical than living on Mars or Titan. It is not unrealistic that in 1000 years there may be as many people living off-world as on. What was human population and tech level 1000 years ago? Each step on that path will look silly to many.

Oh, dang, I didn't catch that it was specifically the tx buffer. Yeah, that seems viable -
As pointed out in the thread at the X post any information based product could work. Design, engineering, whatever. One couldn't telecommute in real time with Earth but a lot of work is done remotely, and often performed better in relative isolation. Maybe Game of Thrones would actually be completed if GRRM were isolated in a studio on Mars? Once the second, third, and subsequent Martian cities emerge along with a Martian orbital city and a Mars-Earth Cycler city perhaps tourism from those places to Earth could become a decent market sector important to Earth. Stop being so Earth centric, Earther

My first thought is make the bad section a data segment that an unused structure points to which prevents any other var or structure getting allocated to that location. But that may entail too much overhead in that highly constrained situation. Will be interesting to see what they do -

Disks, yes, RAM, no. As far as I know (which is nothing on this) Voyager 1 has bubble memory. Time to rabbit hole... Here is a great link I'm still reading through. Not bubble mem, ha ha, IC RAM, from what I can tell, but no disk drive either. Voyagers use tape for secondary storage. And V1's tape is still working? Amazing! https://www.allaboutcircuits.com/news/voyager-mission-anniversary-computers-command-data-attitude-control/ -

I wonder if there is a way to mark bad memory blocks the way hard drives mark bad blocks and avoid them. Probably built in already in newer probes -
The basis of free markets are an emergent reality of life. Even animals and plants engage in trade
-
Even animals practice free market principals. But scientists call it symbiosis or coevolution. The idea that one can't see one being voluntarily trading with another being for mutual advantage as anything other than philosophical requires ignoring evidence right before our eyes. Free markets are natural, "organic", and emergent. No political system anywhere or at any time has been able to keep them from happening and when those political systems collapsed it was emergent free markets that picked up the pieces. Naturally. Two beings trading is not some crazy abstract concept dreamt up by philosophers. Every cell in your body has mitochondria trading services for security. It is built in and emergent. Completely natural and proven by billions of years. Full duration tested many times!

"Great American Eclipse" II: April 8 2024
darthgently replied to cubinator's topic in Science & Spaceflight
I stopped at the no-SSL warning. Without SSL any hop along the path could inject an exploit. Don't have time for sorting that kind of thing out. Even a self-signed cert is better than nothing (still has problems with potential site spoofing though) -

"Great American Eclipse" II: April 8 2024
darthgently replied to cubinator's topic in Science & Spaceflight
Or just harmonic oscillation of extended things like panels from attitude corrections. Like the ISS, these sats constantly adjust attitude to keep one side facing dirtward. The main antennas are phased array I think so that should give some slack in exactness. But I really don't know
