    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 :)

    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.

    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.


  • A given programming language often has limitations which are largely different than the limitations from others. This means that different languages are often used on different kinds of problems. Want something fast, use C. Want to write something quickly, use python. Want it to run on just about anything, use Java. And so on.

    So why don’t we make one ultimate one or a few that fulfill all needs? Well, partially because we haven’t figured out how to do that, but also it’s really easy to learn yet another language once your understand how they work. I can write in python, js, c, c++, c#, Java, kotlin, rust, perl, ruby, php, forth, lisp, and I could keep on going for quite a while. The underlying concepts are largely the same and so picking up a new language is no big deal (though being good at it is a bigger deal). We have so many because ultimately it just doesn’t really matter that we have so many.


  • Final fantasy 7. But for a different reason. I tried playing that game many times wayyy after it’s release but I just couldn’t get into it. But I got really big into final fantasy 6 and I got really big into other JRPGs, so it wasn’t that the gameplay was bad just that the 3d graphic hasn’t aged well. But I also played some pretty crusty PlayStation 1 games back in the day, so it’s not like if I didn’t play it at the right time I wouldn’t have loved it. But just cuz I didn’t play it around release, cuz I didn’t know about it I was a kid, kind of missed out on an entire thing.

    I like the remake but, I don’t think it’s the same.
