I'm going to give you a computer science problem, covered by a software patent (US 4,197,590). Let's see if it's "obvious" to experts in the field.
You're on a monochrome display. You want to draw a PLUS sign cursor, like in a paint program, leaving the pixel in the middle unchanged. How do you draw the vertical and horizontal lines without stomping on the center pixel?
Do you save the center and put it back later? Or what's your solution? No sprites, of course, all done via Get/SetPixel(x,y) only.
Assume something like
bool GetPixel(uint x, uint y);
void SetPixel(uint x, uint y, bool b);

@Robotbeat The limit is brain power to development and maintain a certain level. Apollo being an example of assigning brain power at the expense of everything else, it wasn't maintainable. It will be interesting to see if AI helps or creates a larger load on the human substrate.
English
Tech doesn't automagically improve with time. It does with effort (& insight). Can't just wait 30yrs & expect tech to have progressed. It may have regressed! Likewise, there's no a priori firm limit besides physics that stops 22nd Century tech being developed far sooner.
English
@codingfodder @Robotbeat You could also do stellar engineering. Remove enough mass from the Sun and it'll basically become a red dwarf, burning *a lot* longer. Of course, then it would burn much less bright, so you'd have to move Earth closer. Another option would be mixing more hydrogen into the core.
English
We lied to an entire generation. Not that climate change isn’t real (it obviously is). But that there’s no hope if we don’t neuter ourselves. The future is incredibly bright, and I’m angry at those who lied to young people about this.
𐌁𐌉Ᏽ 𐌕𐌉𐌌𐌉@OrevaZSN
The biggest heartbreak of my life has been watching us sail right past the point of no return on catastrophic climate change without even slowing down. We didn’t even really try.
English
@MaxNighswander @Graham_117 @Robotbeat I am referring to the sun's red giant phase when Mercury, Venus, and possibly earth will be swallowed by the sun.
English
@Graham_117 @codingfodder @Robotbeat Using a bunch of giant mirrors to reflect more light at the Earth would be vastly easier than dragging the Earth closer
English
@Robotbeat @aaronburnett Energy aside. A human has over 30 Trillion cells. If we are going to get 30 trillion humans to get to whatever is next on the emergence scale, we're going to need space. But getting the energy sorted is a great start.
English
@aaronburnett There is no answer that doesn’t involve either space (or dystopia Hell-Earth or large scale geoengineering) past roughly 10-100TWe or so.
English
As I’ve said for more than half a year, you have to see the demand to make ODCs make sense. 50%+ of these respondents are essentially saying there isn’t enough demand. They are wrong but I don’t blame them given the audience.
I think this is siloing problem. Most payload readers are space industry specific and they simply do not use AI enough to see the demand. If you doubt this just go to a space industry event and talk to them. Some of the smartest folks on the planet, annoyed that AI is getting the attention.
Lots of semiconductor/AI folks see the demand but can’t see/understand the physics advantages in space. Often they say something along the lines of chips will get more efficient and hand wave the energy bottleneck to zero. Seemingly as an attempt to avoid needing any other industry.
Meanwhile the compute problem is just getting worse, and we at Mach33 (and others who see the issue clearly) have already moved onto the coming chip shortage.
Siloing explains a lot of the disconnect.
Good luck with your report, Jack!

Compiled a list of market risks to orbital data centers and asked Payload Pro readers which is the most significant. Here are the poll results. Thoughts?

@Robotbeat My kids are all broken up by the eventual destruction of the earth by the sun and now I have to do the math on a solar sail statite to drag the earth further from the sun over billions of years.
English
@davepl1968 @LatFilosof Time is sufficient but not necessary to imply causality. You cannot have time with out causality, but you can have causality without time.
So a simple form could ask what "caused" God. But while that question makes sense, it is completely unnecessary outside time.
English
@LatFilosof I can't believe I'm doing this, but... time and hence causality is a physical manifestation of the universe we live in, and thus anything outside it is irrelevant and the question makes no sense.
English
Unpopular opinion, but this is actually a good question.
It is of course an atrocious argument if you understand what is meant by ”God”, but for someone not well versed in the metaphysics of Aristotle and Aquinas, it’s actually not something unreasonable to say.
English
@Robotbeat How will we know if they are being kids properly if we don't hover?!
I could probably make money on a program to teach kids independent play, since we have more money than sense. It could have an observation deck for parents.
English
Kids will invent games (if they have to) if you leave them alone, BTW. This will come back naturally by just not letting kids have phones, making them go outside, and not helicopter-parenting them.
YIMBYLAND@YIMBYLAND
The most extinct thing in the entire movie isn’t the public pools, the country fair, or block parties. Those all still exist. It’s the idea of kids playing baseball just for fun. No trophies, no tournament, no parents, just play. Travel sports has ruined a generation of kids.
English
@Robotbeat This is why we need to give him loftier goals. A self-sustaining colony on mars with 240 Billion Humans.
English
People are figuring out this is actually the harder goal…
TheHappyHawaiian@ThHappyHawaiian
Elon is putting this is in space supposedly?
English
@Robotbeat @GestaltU The logic is "There is no life off Earth" -> "Life cannot exist off Earth" It is some magical thinking that we somehow don't know or can't reproduce environmental conditions in which humans can survive. I am not sure they are aware of pressurized air and thermostats.
English
@GestaltU Point to the “cannot settle mars” law of thermodynamics. I can’t find it in my textbook.
English
It’s a timeless phenomenon: the Croesus rich end up as cults of personalities surrounded by sycophants and those who share similar delusions. I actually like this as a motivator for Elon, as it will direct enormous non-military resources to space and propulsion tech, but unless we misapprehend the fundamental laws of thermodynamics (many other scientific disciplines), this is effectively impossible in Elon’s plausible lifetime.
The Kobeissi Letter@KobeissiLetter
This is incredible: Elon Musk will receive 200 million super-voting shares in SpaceX ONLY IF the company establishes a permanent Mars colony with at least 1 million people. In other words, Elon Musk will only receive this pay package if 1 million people live on Mars. In other words, Elon Musk's biggest goal is now establishing a colony on Mars with a similar population as Dallas, Texas. Musk is so optimistic about this goal that the vast majority of his pay is now contingent on it. Life on Mars is closer than many expect.
English
@theblessedsalt @JHawleyStan Hmm, the instantaneous acceleration is the same but since a more massive object brings the earth closer the instantaneous jerk (third derivative) is not the same.
English
@JHawleyStan My point is that they’re falling toward each other, which means the different systems have different rates for collision from the same distance.
English
Technically, don’t they, though? Just by an immeasurably small difference?
Daily Roman Updates@UpdatingOnRome
Lmao.

@thynes2537 @gonefishin1948 I am never sure which is sadder. Protestants who don't believe in the real presence and for their services they are correct. Or onea who do believe in it, but for their services are wrong since they lost holy orders.
At least the second have a thread to pull on.
English
@gonefishin1948 Again, don't generalize all Protestants. LCMS (and other) Lutherans believe the real presence and celebrate the Eucharist.
English
What is one thing that the Hebrews were commanded to do and Catholics and Orthodox still do that is missing from every Protestant service?
English
@Arbitrary_user @Noahpinion It wouldn't remotely be a nail in the coffin of religion. Catholicism has no eggs in that basket. We see the body and soul as a unified thing. It isn't as if we think some compute is offloaded to the soul or something.
English
@Noahpinion I really, really don’t want to demystify human consciousness. That would be the final nail in the coffin of religion, which I think may be more dangerous to mankind than anything AI would do.
English
We don't really know if AI is conscious. We'll never know for sure.
But if we figure out the neuroscience of how human beings become conscious, we'll have a much better idea of how to make AI think more like we do.

@Robotbeat @ThePrimalDino @SenJohnKennedy @NASAAdmin Pluto has always been a planet, He is just returning us to the truth.
Now, does the NASA Administrator have any say in daylight savings time?
English
@ThePrimalDino Jared is such a great Administrator. He’s gonna make SLS launch more. He’s going to make Pluto a planet again. He’s not a butthead. (@SenJohnKennedy to @NASAAdmin "We need more people like you in government. We have too many buttheads.")
English
@Robotbeat @Xaraphim I hate that none of the people commenting on these things are willing to give me an expected value. They usually don't even define the population so experts in just about anything fit the narrative.
English
@Xaraphim There are like tens of thousands of NASA engineers fwiw

OK, this is really becoming very alarming now. What the hell is going on here

you should have to post proof of ownership of a casio fx991ex and at least one other dedicated calculator before discussing engineering on this website

@Robotbeat Hopefully they'd keep Starship overall the same size. Just more payload volume. I want to open a mercantile on Mars for all the things people didn't know they'd miss. Maybe McMaster-Carr would be willing to franchise.
English
@codingfodder If you’re limited by liftoff mass: Shrink the upper stage, stretch the booster.
English
This sounds like a small optimization for Starship, but I don’t think it’s small. To use a hypothetical reusable F9 upper stage (a 4.5ton penalty, equal to upper stage dry mass?), you’d get 7.5t RTLS LEO vs ~15t droneship. Even bigger difference for sun synch or GTO.
Robotbeat🗽 ➐@Robotbeat
Build a catch tower in the Bahamas. Consolidate a dozen caught boosters & ship them back on a fast ship. MUCH improved payload efficiency (with optimized staging ratio), but still can get ~100 flights per year per booster (no need for faster than that in the long run).
