I wonder: Is there any experiment done on Mars that uses Spectroscopy to detect water?

I’m thinking of something like this:

Due to Absorbance, wet air should absorb specific frequencies of light.

As the saying goes, there’s only two hard problems in IT:

Caching, naming things, and off by one errors.

glad you like it :-)

lol

1 acre ~ 4000 m²

You need approx. 1200 m² to feed a person, so 1 acre was approx. a small-sized family farm back in the day.

Maybe a tunnel could actually help with this?

AFAIK it not just speeds up plant growth, but also extends vegetation period. It means for example that you can plant/harvest from March-October, instead of May-August.

Thanks, I thought the same thing.

Especially the “getting some physical exercise, and reconnecting with the soil” seem interesting upsides to me. We would all need some more of that in today’s time it seems.

It appears big because it’s well used. Also, the house is small-sized. Might depend on your family circumstances.

Well yeah rice, xD

apart from that i’m not aware of anything.

Also beware, that grains need direct solar irradiation (they need to collect lots of energy, much more than vegetables), so stacking them on top of each other is not viable.

Growing enough grain to feed yourself takes 400 - 1000 m² depending on soil fertility.

So you can’t do that in your backyard. It’s also dramatically more efficient to harvest grains with big machinery, so it’s wise to put it together with your neighbours and form something like a cooperative.

thanks!

Nevermind i misunderstood.

Yes, that house seems to be 500 sq ft

No, you cannot source all of your food that way. Only the vegetables. You still habe to get grains from a machinally-farmed farm. It says so in the description (4).

In exchange, the vegetables are really fresh.

Beware that the problem with rooftop greenery is that a lot of building’s ceilings aren’t strong enough for massive soil.

So either the soil has to be very thin, or it often isn’t practical. Keep that in mind.

The problem is that they’re not really made for this task, both in hardware and available software. They typically specialize in routing and switching, but have insufficient internal hardware (memory especially) to run a full-blown OS.

So whatever you install on these devices, will probably not give you all the features that you would like to have. (For example, a full linux command line with all the typical programs installed.) Also, it doesn’t allow you to use HDMI to connect to a monitor, so there’s that. But basic linux things can be done on it, if you figure out how to get to the command line. But it’s very limited.

So wie die Ordnung stets ins Chaos geht,

wenn keine Kraft dagegen steht,

so herrscht das Chaos nie allein:

Es braucht die Ordnung, um zu sein.

you’re on a highway to hell.

I agree with you especially on the definition order of functions. I, too, define main() first.
