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.

Aren’t these changes, because there are just have bones to look at, so skin properties etc are a guessing game?

But how did that jaw bone double in length in 2001? Was the skull a missing part until then?

Thank you, I didn’t consider that he himself could have politicized sexuality first.

In that case it sounds more like a “rules for thee, but not for me” thing, which makes perfectly sense to point out!

Sorry, I am not from the US. So this guy consumed porn. And what? Relax people!

Might sound weird to prude people, but most politicians had sex before! Some may have kinks! Why do people care about other people’s sex life, if they aren’t attracted to them?

And what has this to do with a community called politics? I don’t get it.

Edit: wow, many replies! Thank you all for educating. If this man is saying people shouldn’t consume porn, then yes, you are all right and it’s a controversy that makes sense to shine some light on. I didn’t think about that.

As I understood it, the dashed line is just the 35°C wet bulb temperature line.

I think it’s the “old assumed border of survivability” and don’t know if it is based solely on mathematics or on other experiments as well.

I also don’t know on how many individuals the new line is based and what age group the older people one is.

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.

Thank you!

Currently I’m using both Boost and Thunder, as both have things I like and both have things I miss, that the other app does have. I’ll see over time if I will settle with only one app and if it’s Thunder I will want to figure that out.

Currently I found a workaround by first adding like 10 returns on the bottom of my text so I am able to see what I write above.

(This comment I will post with the additional returns at the end to see if they get automatically removed or not. According to the preview option they won’t be visible.)

If it had a stable orbit before and then slowed down, I thought it’ll get a more elliptical orbit, being both closer and further, or fall into Earth.

My logic was that a stable orbit closer to the center needs higher speeds to counter higher gravity and vice versa.

So if the moon would get hit in a way that makes it slow down and get pushed further away from Earth at the same time, it could keep a roundish orbit, or not?

What’s with that specific timeframe? Is it due to the orbit never being perfect? Or random slight influences from other not too far, heavy objects?

Thanks for the explanation, the moon being a little fast for it’s orbit and therefore slowly spiraling out of Earths gravity makes sense to me now.

I know you’re right, have read it elsewhere before. But I can’t figure out why that would happen. I doubt Earth is loosing mass. Does the moon slow down over time due to impacts or what causes this?

I use mosquito coils, they are very effective.

I also have an electric bat, although it’s more for the phycho fun of killing than helping reducing bites. They are just too many.

I tried lemongrass as a natural deterrent but had the impression it made no difference.

What works best for me is: slapping those you can while not caring about the rest. Because once you start to scratch it’s a vicious cycle, so I don’t touch stings and usually then forget about them shortly after.

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.

I disagree. I live in mosquito land and get bitten a lot. I’d say the majority of mosquitos biting me, I feel when they land, before they bite. Probably half of those I can either slap or miss and they take off again and try again. There are some spots though where I don’t feel them land. The annoying ones are those I feel touching me but they don’t land, they just fly around. Those are hard to slap.

Unrelated question: does anybody happen to know if the biting time matters for transmitting disease?

2 mosquitos died on me while typing out this comment.

You’re right. I didn’t even notice the second jeep before. It looks like this was done on purpose, which is kind of stupid, especially on the jeep driving behind the other. The grill is there to protect the radiator from debris. Once the radiator gets hit by a a small rock and starts to leak, which can happen quickly, as they are usually made of very thin metal, you’d have to constantly monitor engine heat and fill up cooling water regularly.

This was an accidentally duplicated comment due to poor mobile data service in my area.

I don’t think this would improve cooling, as the bottleneck of airflow is probably the radiator, not the grill.

All I can guess is that the grill was damaged and removed.

Edit: accidentally commented this twice due to poor mobile data service.

Unfortunately my hardware is too old to play games that are like that.

But I’ve noticed the same with mobile games. My policy is: if that single player game doesn’t start without internet access it gets deleted.

I would go even further and say that the perception of the voters outweighs reality.

Ironically education is a good way for people not to radicalize, I believe.

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!
