I'm sorry for anybody living in the US right now. The only hope is that it will get better, in the far future, when all those billionaires will have transported themselves to Mars. Then you may find some peace, I guess.

Yeah I do that too. When I get really enthusiastic about something, I can talk about it for hours. So, it exists.

I was told it is apparently an ADHD thing. Because some people I used to meet, did the same thing, about their favorite topic each. So, it's an ADHD thing, apparently.

But I'm glad you can bring up the mental energy to talk about a topic for a long time! That means you're healthy :-) (imo)

The most important ones that come to my mind:

  • Maps (like Google Maps, just FOSS) ideally with transportation routing for every country. This could be a lot of work and is definitely not a "small project".

  • Browser (like Firefox). Like 50% of everything I do happens through the browser.

  • File Explorer, PDF viewer, ...

maybe some puzzle games to play when bored. I don't really use much else.

Oh and a Youtube alternative would be nice, but not necessary. You can already visit some through the browser.

First of all, don't feel bad for not having sex. The right to a self-determined life is important, be it sex or no sex.

I'm very sorry for your story. If you'd live in a society with better social welfare, I'm sure you'd do much better. Unfortunately, I don't really have good advice for what to do in your situation.

reminds me of this:

https://en.m.wikipedia.org/wiki/Panopticon

Note, though, that the Panopticon is also referred to as a "prison design". So, quite the opposite of "freedom", depending on how you see it.

Life is like a dramatic river flowing through the rapids.

I have gained so many things in life, and lost them again, and gained others, and lost them again.

I do not predict the future. Let's wait and see.

May I suggest something?

In some countries (like Germany) they have special hotels which are essentially free or low-cost, which have the sole purpose of helping women or people in a difficult, abusive relationship gather some distance from their abusive partner. In German they're called "Frauenhäuser" (women's houses). Maybe such a thing exists where you live, too?

I'm sorry for your encounter. They were an asshole and it's not your fault. Such encounters exist, but are rare. I hope you will be able to see that these cases aren't the "normal scenario", and not something that you will always have to expect. Hope that helps you :)

I just wanted to say I read the whole post with an incredibly southern accent.

Experiences: Why did you do it, how did you feel afterwards, did you regret it, did anything change in you afterwards?

Isn't the internet anonymous enough for you?

I wanted to add that i really really really did not want to hurt her. I'm just that dense (even if you can't imagine it) and my gut feeling told me that would be a fine thing to do.

 

If you mine something, you can't mine it again. It's gone from the ground.

If you harvest something, then wait a certain amount of time (a year, for example), you can harvest it again.

Is Water on Mars a renewable resource?

 

... and neither does the author (or so I believe - I made them both up).

On the other hand, AI is definitely good at creative writing.

All life is based on large quantities of Water. The same will be true on Mars. There has to be a major and reliable source of water on Mars.

What options are there? I read an interesting article yesterday that said "Our results show a two-order-of-magnitude diurnal variation of water vapor pressure, suggesting a strong atmosphere-regolith interchange", in other words, the soil on Mars extracts water out of the atmosphere in the nighttime and releases it in the daytime. This means that if we collect the soil and "bake" it, it would release water vapor in a controlled environment. We could then condense that water vapor to get useful/useable water.

 

Hear me out. This thought process requires a bit of knowledge of physics/chemistry.

On the martian poles, there are vast quantities of frozes CO2. This frozen CO2 exerts a certain "vapor pressure" - in other words, a certain partial pressure of gaseous CO2.

Now, if we convert this CO2 into O2 by removing the carbon out of it, the concentration of O2 in the atmosphere increases. And therefore, the concentration (and partial pressure) of CO2 decreases.

But since the frozen CO2 on the poles causes a certain partial pressure of CO2, a bit of the frozen CO2 will go into gaseous phase to refill the CO2 partial pressure.

So, by converting CO2 into O2, the concentration of O2 increases, but the concentration of CO2 stays approximately the same. As such, the total pressure (and density) of the atmosphere increases. This would happen if large-scale biological photosynthesis/growth took place.

Any thoughts?

Does anybody have good data on what radiation exists in space?

I have found sporadic information, such as on Wikipedia but I wonder whether there's nicer, clear structured information on this topic?

Hi there, I'd like to connect with people to discuss technical aspects of settlement of mars.

I'd look at a house on earth and ask: what things have to be supplied from the outside; what things can be produced inside the house? Houses on earth have piping for water, and cabling for electricity.

Plants can be grown in a green-house using these two ingredients, and the people can sleep in a spaceship.

Comment whatever comes to your mind.

 

There is a decentralized YouTube alternative.

Video hosting is notoriously expensive. PeerTube circumvents this problem, because videos aren't stored on some single server, which would cause high bandwidth cost for the server operator, but largely by the users after they watched them, similar to BitTorrent. This way, the cost of video hosting is distributed among the clients, by using their internet connectivity for sharing.

I believe that PeerTube is an interesting project, and I'd ask you to check it out. It's cool.

Similar to Lemmy, it's not a single running server, but rather a software that can be used to set up a server. So there's many instances. I'm still exploring which instances are interesting. If you have any recommendations, I'd like to hear them.

 

I cannot explain why but I feel that this belongs here.

What is shown is some kind of re-interpretation of the "princess and the pea" saga. Instead of showing the princess' over-sensitivity to small things, it displays the princess' love for plants and nature. In this way, sensitivity is interpreted and seen as something positive, which I can appreciate.

Tell your republican friends/colleagues/whatever that solar panels are a good thing because they let Jesus into our lives.

Hopefully that will accelerate the green energy revolution.
