then they should hand out access tokens at the supermarket (need to be 18+ or 16+ whatever the age limit will be)
- Comment on If God (or any creator of the universe) exists would he be made out of atoms? 2 days ago:
god is a set of mathematical statements or at least that’s how to interpret it in a modern sense, 2000 years ago these views didn’t exist so they just called it “the metaphysical realm” but it’s not made of atoms, no.

the only way to have privacy-preserving age checks is when there’s a variable on the phone that stores whether the user is old enough. and gives that data forward to apps/websites trying to do age checks.
that variable can only be changed if you’re the rightful owner of the device, i.e. if you paid for it and have a code that’s on the purchase bill or sth. and children wouldn’t have access to that.

It would be nice if there was an actual article discussing how the parents controls on android phones actually work.

Ja und das kann man mit einem CO2 scrubber machen, der entfernt nämlich nicht nur CO2 sondern auch H2S (Schwefelgas). Aminwäsche

thanks :) i will look into it when i have some time for it :D
- Comment on i can't handle coffee 3 days ago:
pretty good way to summarize my opinion of it as well :3
- Comment on i can't handle coffee 3 days ago:
at least it seems to be a widespread phenomenon. i could always handle coffee easily, drank 3 of them along the day. now i can’t even handle a small sip or my heart starts to race. idk why that is.
- Comment on i can't handle coffee 3 days ago:
i actually misread the comic as “four little sips” at first.

- Comment on Chocolite 3 days ago:
or my tastes have changed, because the ones I have tried in the past few years just aren’t good.
chances are that as you get older, your taste changes. i liked lots of sweets when i was younger and now i just can’t stand them anymore.
also yeah, recipes have changed as well. factories want to make their food “healthier” so it appeals to the consumer who tries to watch their diet and as a consequence they often use less artificial flavors (i actually don’t have a data source on that, it’s just my personal impression/observation). like everything used to be chock-full of artificial flavors in the mid 20th century, and now they’re not so much anymore.

where i live we have both chocolated fruits and nuts (like nuts dipped into chocolate, which is delicious btw) and animal-shaped chocolate (mostly chocolate bunnies for some reason)

we have approximately the same brain they have, so anything we could come up with, they could come up with.

it’s really impressive how smart people were back then. we completely tend to underestimate that.

- Comment on I hacked mars! 6 days ago:
You’d also need to deploy the system, or find a way to maintain it all the way from Earth orbit to Mars’ surface.
You can use the spaceship as a habitat! That way you don’t need to ship an extra habitat … an advantage of reusable rockets.
As for the ship size, starship has about 1000 m³ volume of living space, so you can have a mini-greenhouse in there for growing some vegetables and salad (since those have to be fresh). You have to bring high-calorie food though or grow it outside, since it consumes more area.

I think more important than the raw energy and oxygen is sourcing the water
yeah i actually believe that too. i calculated somewhere that it takes around 10 kWh per kg of water extracted from the soil, assuming you follow this process and assuming a 30% water content in the regolith.
So yes, total energy consumption is a bit higher, but it’s only a rough estimate to give you an idea of the order of magnitude that we’re talking about.
Also i wrote about food production here.

- Comment on I hacked mars! 1 week ago:
seriously though, any serious attempt to live on mars would obviously use electrolysis of water to produce oxygen on mars, because to do so you only need electricity and water.
and about how to get electricity, see my post here
and about how to get water, see my post here and this article.
and then you could produce O2, which you’re gonna breathe in, and you’re gonna exhale CO2, which you then need to remove from the atmosphere, which you can do with a CO2 scrubber

also bring seeds, lots of seeds, in case something goes wrong and you need to re-plant everything.
- Comment on I hacked mars! 1 week ago:
biologically, humans aren’t that special. if you can reliably sustain insects in an ecosystem, it’s not that big of a jump to feel humans as well.
