Trump’s tariff plan will send prices ‘through the roof’, warn US firms
  • 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.

  • Does anybody else always find themselves sending large enthusiastic texts to people but don't usually receive such texts?
  • 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)

  • What Apps Are Missing on Mobile Linux?
  • 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.

  • [Off my chest] My asexuality + disability has ruined my life and I don't know what to do
  • 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.

  • What did you lose along the way and how will you restore it or make things right again?
  • 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?

  • What did you lose along the way and how will you restore it or make things right again?
  • 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 :)

  • Have you ever sexually harassed someone?
  • 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.

  • Have you ever sexually harassed someone?
  • I'll go first:

    Yes, but not in bad faith. I really liked a girl in school and at some day after school (we were sitting together to do some exercises) I awkwardly approached her and tried to kiss her. To my defense: My autism is strong and doesn't tell me when things are awkward. She pulled back and I realized how shocked she must be, so I awkwardly apologized. She said "yeah yeah it's fine". and i left. The next day, however, she avoided me and we didn't talk afterwards.

    I'm guessing that it was in fact not fine, and I'm sorry for making her feel bad. I'm not sure what to do, I never saw her again because my parents moved away so I changed school afterwards. I'm thinking about reaching out to her and apologizing again, but I'm not sure whether that's such a good idea (it happened more than a year ago and I'd have to count on chance to figure out a way to contact her.)

    Call me a nutcase but this story is true. Save yourself all the "ooh you're such a bad person, you shouldn't have done that". Can anybody relate to this experience? Has anybody direct experiences being on the other side of this? I'd like to hear them. Thanks.

  • Have you ever ghosted somebody?
  • Yes. I've once ghosted a close friend of mine, because I had difficult health conditions and needed a break from school (that's where we met). I didn't want any human contact, so I just isolated myself and changed my phone number. It was unfair towards her, because she was a really likable person, but I just couldn't handle any human contact at the time. I regret not telling her.

  • What is a "leopards ate my face" moment?
  • Question: why is it called "leopards eating a face"? Why is it leopards and not, say, rhinos or dolphins or geese? Why do they only eat faces? Do they not eat the rest of the body?

  • Will water on Mars be mined or harvested?

    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.

    The book does not exist

    ... 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.

    The significance of water on mars

    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.

    Mars' atmospheric density will increase due to oxygen.

    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?

    radiation in space

    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?

    official discussion forum?

    Hi there, I wonder whether there is an official discussion forum for all things of the mars society / settlement of mars? Where may I find collected resources and knowledge?

    The Universe Will Not Die a Heat Death

    I just wrote this article and I would like your comment:

    The Universe Will Not Die a Heat Death

    We assume that the universe is expanding according to the Lambda-CDM model with a fixed Lambda constant.

    Imagine a central star, like our sun. Two artificial satellites are orbiting this sun in circular orbits in opposite directions. As the universe expands, the orbits of the satellites are elevated, and the satellites thus gain mechanical energy (the sum of potential and kinetic energy). This energy can be released by causing the satellites to collide or by simply having them graze each other. As a result, some of their kinetic energy is converted into heat, which can be radiated away as thermal radiation, and the satellites descend to lower, more inward orbits. The process can then begin anew.

    essential elements for survival on mars

    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.

    TIL: PeerTube

    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.

    The princess and the pea

    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.

    I, for one, welcome our solar overlords

    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.
