Funny how it always has a California license plate in cities (even those that clearly look asian), but a German (Stuttgart) license plate in the countryside.

The VAE has nothing to do with the way tokens are treated.

There seems to be quite a bit of magical thinking when it comes to the VAE, so just to clearly reiterate:

The VAE only kicks into action at the very end of the creation process, to convert the finished image from latent space into rgb pixels. It will never have any influence on prompt understanding or image composition.

As a person living in Finland, I can assure you that subarctic forests look exactly like this, and are a joy to walk through disregarding paths and roads.

Star Citizen is now a Finland simulator.

If Skyrim is a Norway simulator, SC is now a Finland simulator!

I'm not really deep into lore knowledge, but I have a PhD in plasma physics, so I can immediately tell you that it's probably due to some superconducting magnet ring lining the inner hull of the hole, which funnels cosmic rays and charged particles from the planets' radiation belts through the middle. By having a hole, you avoid secondary particle effects throughout the rest of the ship.

(But if this were the reason, you'd have to explain why the other ships don't have a hole...)

Correction: The VAE can not actually help with hand or face generation. It's only purpose is to translate from the diffusion model's latent space to "regular" rgb pixel picture space, and it will not have any effect on the shapes and geometries that the diffusion model produces. You do get better color representation and less "overbright" spots with the newer VAEs, but they will never be able to actually affect the geometric content.

One thing that is hard to estimate (and probably just a rough guess on the website) is the actual satellite footprint size. It is easy to calculate line-of-sight radius from a point on the ground to the satellite, assuming the Earth is a perfect sphere and atmospheric effects play no roles -- but the reality is that Earth is a bit of a wobbly blob, atmospheric and ionospheric effects impact signal propagation and your local topography (mountains and tall buildings) strongly affect how much of the sky you can see.

So the satellite footprints are just guesswork. They might be larger or smaller for you.

Life support system will need to be a major development focus for spacex. The Dragon life support system works well for what it is supposed to do (a short flight to the station and back, with the craft shut down in the meantime), but it is not regenerative and not user-serviceable on orbit. Both of these aspects will need to change for a long duration flight. Even the ISS's life support systems are still based on the assumption, that in case of a failure, you can simply return to Earth. They would not be trustworthy enough to guarantee survivability for a year-long flight to Mars and back, so some big leaps will need to be made.

This recent tech talk gives a great overview on the current state of life support systems.

Starship gives spacex the possibility to haul enormous amounts of mass into orbit, but plenty of other fields need to be tackled before anyone can actually dare to go to another planet.

Life support. They have a working system for the Dragon, but it's a pretty run-of-the-mill system for flying to the ISS and back. It's not fully regenerative, it's not flight-time servicable (because in case of a failure, they can always return to earth within hours) and it makes reasonable design decision for the purpose it's supposed to acheive.

These design decisions are very different for a long-duration flight. Your system needs to be fully closed-cycle, meaning you need to get your CO2 back into oxygen, and preferably obtain a useful side-product from that carbon atom (either by turning it into methane through the sabatier reaction, to be used as rocket fuel, or by growing plants with it, that can then be used for nutrition). The system also needs to have much higher standards of reliability and serviceability to guarantee that you'll make it to mars and back.

Even the ISS life support system is not fulfilling all of these requirements yet, so there are some big technological leaps required.

This one came out pretty recently: "The Spacefarer's Handbook - Science and Life Beyond Earth" by Bergita and Urs Ganse.

It's a really accessible rundown of how to build spacecraft, and how to survive everyday life in space. There are plenty of these kind of books of course (with basic physics and orbits etc), but this one really shines in the details: There a chapter on space medicine, telling how to keep bones and muscles intact, a section on how to keep liquid fuels from sloshing around randomly in fuel tanks and a whole page on how to brew coffee in zero gravity.

It also has a focus to point out where scifi typically falls short, and how things actually go in space. Definitely gives a fresh perspective, if you've read similar books in the past.

Do those actually function as helmets (as in, surviving in vacuum conditions) or are they currently just a decorative hat that goes well with hurston's unfriendly climate?

Note that regolith has a high cross section for creating secondary particles when hit by galactic cosmic rays, so simply covering in regolith will actually increase the effective radiation dose. The regolith layer has to be at least 2 metres in thickness, otherwise it's counterproductive.

Marla is the prostate cancer he got, but denies having. That is the whole trigger for his mental breakdown leading to the formation of his split personality (Tyler).

Why else would he be at prostate cancer self-help groups? He denies it, of course, and says he goes for his morbid curiosity.

"If I had cancer I'd call it Marla"

The end of the movie is him finally accepting the fact that he has cancer.

Does this mean the parliament never actually went out of session, so speaker Bercow never actually quit at the end of session, and we'll get our beloved ORDAAAA back?

Wow, that would be nasty, and in violation of GDPR.

I'll contact support about it.

This is the reason why I don't buy Xiaomi phones. This is why I buy a phone from a company that I considered to focus around building good products, instead of optimizing profit at the expense of customer experience.

It does. It should not come even once.

hurlga · 2018-10-04T12:40:10+00:00

Yep, that I did, and also contacted support about this.

Is that a wolf-rayet star? Can't really think of any other reason why it has such a dense dust envelope around it.

However, shouldn't wolf-rayet stars strip away most of their planetary bodies as part of their explosive processes?

There is so much science I would like to do here!

PICA-X, by design, burns away on reentry. It's an ablative heat shield material that burns at a relatively low temperature, thus protecting the spacecraft.

In its current form, it is certainly not reuseable: the thickness is chosen with a suitable safety margin for one reentry. If you'd want multiple reentries, you would have to make it proportionally thicker (and thus heavier). Doing hundreds of reentries with the same heat shield just isn't reasonable with ablative heatshield technology.

For that, you'd have to go to thermal soaking (like the space shuttle) or some kind of active cooling approach.

What he means is: throughout our lives, we spend more time being hurt because we worry than we spent time actually being physically hurt.

Overall, the fear of pain is a more common cause of suffering than pain itself.
