In more realistic scenarios, “down” is just defined by the direction of thrust. So approaching a ship, they will be down assuming you are decelerating to match their velocity, but they will be up if you are still thrusting towards them.
But all of that has almost nothing to do with how people will think of orientation to other ships since generally speaking you won’t be using eye sight to communicate ship to ship. At that point an agreed upon down will be needed. Probably aligned with galactic or star system to establish a plane, and probably right hand rule to establish up and down. In general given that space is big and ships are small they will just be points on each others radar until they need to dock with each other so it doesn’t really matter how people are actually oriented, as long as when they communicate what they say makes sense to the other side.
edit: or maybe down is towards the currently orbitted gravity well, like towards a planet/moon/star.
Actually, space in general is mostly 2 dimensional, in that all the interesting stuff generally takes place on some sort of almost flat plane. A star system is generally on a plane, so is the galactic system, and for most planet+moons too. They just tend to be different planes so for ease of communication you will probably just align your idea of down with whatever the most convenient plane is. This of course is ignoring what gravity down is, as that changes as thrust does.
And as for ship alignment, yeah no one is going to worry about that till its time to dock, at which point the lighter vessel will likely change their orientation since its easier and takes less energy. Spaceships are not going to be within human sight range of each other most of the time, even being in relatively the same are. Space too big and getting ships close to each other is dangerous!
But in media that fucks with people’s idea of meeting and seeing each other so for convenience of not confusing the audience you don’t see that level of realism often.
Realistically their does need to be some consideration but the medium they travel isn’t air, but the occasional speck of dust, hydrogen atom, and other small stuff. It’s not much but for interstellar travel there are still considerations needed, namely reducing your cross sectional area in the direction of travel. Long and thin gives you less drag since it hits less stuff.
Regardless the airplane looks doesn’t make much sense anyway :)
There have been some impressive (and scary) temperature records set in the past couple weeks. That said, there are parts of Canada that are currently on fire that likely have a daily temperature in the hundreds of degrees. Clearly that doesn’t count for any sort of temperature record. What I’m wondering is: where’s the...
Well, the record high temperatures are what cause the forest fires so we do have to take that into account. And the radiant heat that the fire gives off dissipates with the inverse square law so that limits it’s contribution. Really it seems that the only major contributing factor to the increased heat, other than the effects of the already high ambient temperature and thus the decreased apparent humidity, are the excitation of the air molecules as they are transformed from elemental oxygen and plant matter into hydrogen hydroxide and carbon dioxide, along with other molecules due to incomplete combustion and contaminates. Overall I think a safe bet would be 2.
Necessity. When most of the software you use is reliant on Windows it’s hard to make Linux your daily driver. That being said, the changes needed to make it worth it are already done in limited contexts. Steam deck is pure Linux, the user interface and everything is implemented in a way that the user does not have to deal with the complexity, but the underlying mechanisms for doing wonky shit is still there if you want to mess with it. It’s kinda the best of both worlds in that sense.
If we wanted a desktop experience to replicate that, you would just have to do the exact same thing. Abstract the user experience such that the layperson does not need to engage with the complicated bits, but leave them there for those that do want them. And arguably that is being done with some distros, but it’s just not quite there yet.
Space is 2D, right? (lemmy.world)
How far from a forest fire do you have to be for a daily temperature record to count?

Those who tried Linux and went back to Windows, what caused you to go back to Windows?
Additionally, what changes are necessary for you to be able to use Linux full time?
