also today i am switching from spacemacs to just vanilla emacs with evil. spacemacs has been good to me but it's too hard to modify and it only works if you never try to venture into the rest of the emacs ecosystem.

I specifically wrote it to be the base of a n-body solver but like all my projects I moved on to something else.

eschaton posted:try doing this oh i am, it's just funny that even though i've been using emacs for a few years and have written my own modes and stuff, i have no idea what i'm doing with a bare emacs install. i have helm and projectile going now and things are feeling better. buffer management sucks but i'm going to relearn it from scratch because I wasn't happy with how i did things before. I've never really found a buffer management strategy that I liked in either emacs or vim. oh yeah, and I got scala (ensime) and rust (via eglot and LSP) working okay. neither feels especially great but that's more to do with not being comfortable with this setup in general.

no idea! I got just enough numerical methods to do CFD and simulink stuff, and undergrad level celestial mechanics they sound fancy though so I’d put em somewhere other than then “less than rk4” category. I mostly wanted to point out that Euler integration isn’t sufficient for orbit simulations regardless of timestep, which could cause headaches if you weren’t aware.

i think for now i'm going to try to split my time between doing the 8080 emulator and working on math via the celestial mechanics simulation. i think those are suitably different problems that address different weaknesses in my foundations.

wikipedia posted:The Euler method is a first-order method, which means that the local error (error per step) is proportional to the square of the step size, and the global error (error at a given time) is proportional to the step size. The Euler method often serves as the basis to construct more complex methods, e.g., predictor–corrector method. so if the step time approaches zero error does too, but you always accumulate error. it’s ok in some circumstances, but to get a sufficiently accurate solution your time steps get so small that your computation time explodes and it only would work for a fixed total simulation length with a large enough error budget. totally inappropriate for an open ended simulation. rk4 introduces four Euler level integration steps per timestep but allows you to run much larger timesteps without accumulating amplitude or phase error if your timesteps are small enough to capture the wavelength of the simulated phenomena. (edit: probably related to nyquist frequency but I don’t know the exact relationship and I’m sure it’s more complicated than that) adaptive RK methods use a combination of eg fourth and fifth order RK integrators to make sure the primary fourth order integrator uses the correct size timestep. this is the technique matlab’s ODE45 function uses (specifically the Dormand-prince algorithm) and it helps you get the most bang for your computational buck, which is important if you have a complex calculation to perform for each system state calculation. there’s lots of other techniques but those are the ones in most familiar with.
