  • I assume that the submarine producer gives stats like empty weight from which the current weight can be calculated.

    However, weight isn’t the important thing in a sub. It’s the weight to volume ratio, or buoyancy.

    A sub sinks when buoyancy is negative and rises if the buoyancy is positive.

    There are three common ways to achieve the changing buoyancy: the most simple one is a vessel with positive buoyancy adding droppable weights until the buoyancy is negative.

    Other ways are a neutral buoyancy vessel that uses it’s engine power to push itself up or down. Or a vessel that can change it’s buoyancy by filling up tanks with water (to reduce buoyancy below neutral) and blow them out with air or other gases lighter than water (to raise buoyancy above neutral). A combination of several methods is also possible.

    Hey, welcome, fellow noob!

    I hopped on the Linux train maybe 20 years ago and haven’t had any non unix system in maybe 15 years.

    Also, I don’t know anything much. I can do basic tasks with a Terminal, but I don’t think for example I could install Arch from scratch. Or if I’d accidentally opened VIM, I’d have to kill power to get out again. But I like to tinker. If you like to tinker it’s a big plus, otherwise things, that don’t work instantly, might get frustrating.

    As others said, use a pre built distro + DE environment, especially if you don’t really know what you do. Another thing that I’d recommend: a distro that be backed up easily. So you can tinker and start over, if necessary.

    If I don’t know, how to fix a thing, I usually look up my question online. The problem with that is: I’ll find solutions containing commands that I don’t know, what they do. I have “fixed” my OS to death before, so it’s always nice to have a recent backup.

    Ubuntu is the biggest, although it’s not old-school like win98 and comes with idealistic problems for many people. If you didn’t really enjoy it, I wouldn’t go back, just because it has the biggest community. Community isn’t only about size.

    Mint is rock solid, I’ve run that a long time with different DEs.

    Another distro, I can’t really recommend (as I haven’t used it further than live USB yet), but might be very interesting for you, is MX Linux. It comes with simple DEs and more importantly: a ton of GUI tools (including a back up tool where you can back up the entire OS including apps and settings as a flash USB).

    I don’t know, if I was able to help anything. I just wanted to reassure, that there are (maybe even many) Linux users that don’t really know what they do.

    As with many skills in life, I believe, the best way to learn is by just doing it. There will be failures. And each failure is a big opportunity to learn something.




  • The article is about an experiment, where people are exposed to 35°C wet bulb temperatures, but in different settings. Sometimes lower temperatures but higher humidity, sometimes vise versa, but always 35°C wet bulb temperature.

    So far the assumption was, that humans can’t survive a 35°C wet bulb temperature for longer than 6 hours. And at current warming this is unlikely to be naturally the case within this century.

    However the experiment gives hints to believe that humans can’t survive at lower wet bulb temperatures either. It looks like with lower temperatures and higher humidity, humans can get very close to that 35°C wet bulb temperature, however people seem to struggle more with higher temperatures and lower humidity.

    A possible explanation could be, that while more sweat evaporates in lower humidity, the body has a limit for how much sweat it can produce. And if you keep raising the temperature, that the human body simply can’t produce enough sweat to cool itself.

    That’s pretty much what I took away from the article. They mentioned they experiment with several people, however the article was mainly about on person in the experiment, a 30ish year old, athletic male.

    Edit: add some graphs from the article. Sorry for low quality, but as you said, the layout is quite atrocious and on my phone it keeps jumping around on it’s own, so I lost patience.

  • The second big change is that when you transition from one age to the next—there are three ages, Antiquity, Exploration, and Modern—you’ll pick a new civilization to lead, one that was at the height of its power during the age in question. So you might go from controlling Rome in Antiquity to Mongolia during the Exploration age.

    Well, I still play civ4 bts, never went beyond civ5 and unless I update my hardware probably won’t try civ6 and civ7 anytime soon.

    But what you mean, you’ll change civilization midgame? I can’t wrap my head around this concept. Or does your civilization simply change it’s name?




  • Maybe they are different. I live in Asia. From what I heard there are many mosquito species, but the majority not blood sucking or at least not human blood sucking. Only few species carry disease, if I recall correctly.

    To be fair, when I’m preoccupied, I also don’t feel them always. Or I feel them but my hands are busy, so I can’t slap them. I often have this at night, when I’m playing PC games and my feet get stung up. It’ll be like “ouch, my foot! Gotta slap that mosquito, but first I finish this in game. And then this. Procrastinating until it’s too late.

    I believe ankles are prime for them due to thin skin.

    One mosquito died, writing this comment.







  • Thank you for the detailed explanation!

    I see. Yes I watched the debate and he really didn’t do well, like he was on some medicine and partly asleep. My favorite part was when they discussed who is better at golf. Was a very important thing to get clear for people like me, that are worried of climate collapse.

    But this isn’t new to Biden, is it? Confusing names and numbers has always been a Biden thing, I think, it’s not necessarily a health decline. Like my favorite American president quote is “America is a nation that can be defined in a single word: ashofootnae ehfoot, excuse me, at the foothills in the Himalaya

    That’s why I thought the democrats had a meeting after the debate and saw that Biden’s campaign is not going well and the public thinks (doesn’t matter if rightfully or not) Biden is too old and mentally declining. Maybe, in order to save the sinking ship, it’s best to play a rather risky move of changing the nomine just a few months before election. Or maybe he was also peer pressured.

    Anyway, if it was Biden’s initiative he does deserve a lot of respect for it!
