I never understood why Program permissions is such a big deal on Android and IOS, but not on Desktop Windows/Linux, where any application can to everything.
> if you are applying torque to someone, then that thing is applying an equal and opposite torque back
Yes, just like with a force.
> but in the real world there is friction and air resistance where you have to keep applying torque to keep something spinning at the same rate
Yes, but I think you are forgetting one thing: If the friction is between the rotor and the body, then this friction does not only act on the rotor, but also on the body. I.e. the friction creates a pair of torques which the engine can perfectly counteract with it's own pair of torques.
If the friction is between the rotor and the air, then yes, the spacecraft needs some kind of counteraction or it will start turning.
> It would be nice to hear updated thoughts when you have a chance to try all of these improvements (especially when v1.9 comes out with the cached binaries)!
I finished my Master in physics. Now, I'm working in IT, and even tough physics will always have a special place in my heart, I probably will not return to physics.
If I will find myself doing Numerics, I might give Julia a second try, but I don't think I will find myself doing numerics anytime soon.
Maybe if I buy a SDR and have some fun with it, I might use Julia.
Tell HN: Copying and pasting from ChatGPT unsolicited sucks
> I can understand why you might feel that way. Copying and pasting from ChatGPT without permission can be considered rude and disrespectful. It's important to always ask for permission before using someone else's work, especially if it's for a public forum like Hacker News. Not only is it the ethical thing to do, but it can also prevent potential legal issues. Additionally, using someone else's work without giving them credit can take away from their hard work and efforts. It's always best to give credit where credit is due and ask for permission before using someone else's work.
