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.

three, on three different instances. It’s called redundancy.

Well, what we need is some dedicated non-profit company making chips.

Two plates of rice or noodles with vegetables and salmon. Delicious. Actually, highest ROI that you could possibly hope to achieve in the universe.

Honestly, having a declarative package manager is pretty important.

Consider the following: We’ve had the transition from Sys V Init to Systemd recently. But what does it actually mean?

It means, that instead of running a command to start a service, you now flip a switch in a clear, standardized way. The advantage is that you can get a table-like overview over all the services that are currently running. You get an overview, in other words. That is worth a lot because it brings structure and clarity into your system.

Now, with package management it’s the same way. Instead of running a command to install a package, we should instead give a list of all the packages that we want to have installed, and the package manager should take care of making sure that they are installed. That would improve clarity, because you get a list of all the packages that are installed. It might also increase efficiency if you’re installing many packages, because large parts of the work can be done in parallel. And importantly, you get reproducibility. Imagine you just have a file where it names all the packages that should be installed. You can just take that list and copy it to another machine. Now you’ve cloned your package installations. I guess things like Docker, with their docker files, are kinda already going in that direction. But it would be nice to have support for it in the mainline operating systems.

This reminds me of The Four Leaved Clover

Beware that four leaved clovers can also be seen as a sign of good luck.

Das Chaos, das sich selbst bezwingt,
indem es langsam Ordnung bringt,
gebiert aus Dunkelheit und Dreck
schön langsam, aber stetig, Form und Zweck,
kurz: Leben, das sich selbst erhält,
und auch im Sturme Kraft behält,
um nach dem Regen neu zu blühn,
so wie auch wir es alle tun.

So wie die Ordnung stets in Chaos geht,
wenn keine Kraft dagegen steht,
so herrscht das Chaos nie allein:
Es braucht die Ordnung, um zu sein.

In my personal experience, if I learn it wrong first, then I will keep that mistake. That is why learning it right first is so important to me, and I can only do that in peace, without disruptions from bystanders.

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.

Worst: You tie the knot, go climbing, fall down, knot doesn’t hold, you go to hospital or die.

Actually, it’s the same for me.

It is because others put up a lot of pressure to “get it immediately”. I’m not stupid (I swear) but it takes me like a solid 2 minutes sometimes to understand something. Others expect me to get it in 5-10 seconds.

big if true

A large part of oil can be replaced with electricity. Please point to examples where neither solar power or renewable biomass are sufficient.

Regarding the problem of running out of oil, I look at it a bit like, “we are a plant (biological plant)”.

The plant starts in a seed, which provides it with nutrients (energy) as some kind of starting bonus. It can use these nutrients to develop itself and live, but it will recognize that at some point it will run out of calories and die. So it has to do something about it. What it does, is to develop leaves. These leaves collect the sunlight and this way, the plant has a constant and continuous source of energy/calories. So it can keep on living.

Society has a very similar problem. We have oil, but it is limited. We can use it to develop, but eventually we’re gonna run out of it. So we have to do something about it. Just like a plant, we develop solar panels to collect the sunlight, so we have a continuous income of energy. This way we can live waaay beyond the time of our starting bonus.

Oh no you can’t. Building a ship that can cross the ocean (without you drowning first of course) is actually quite difficult. Not only does it have to be extremely durable, you also have to have a lot of knowledge to navigate. And then there’s the economic problems, like who pays for it, how do you get enough food, etc…

“We’re pushing the can down the road. Problem is, we’re running out of road.”

My father. He’s just a fine dude. Does a lot of things right, is never angry at anybody for too long, and just generally understands what’s important in life and why.

yes that too
