Yep, 10-15x speedup using 16 cores. I think the operational machines have 32 or more cores, so this is great. Gets our final runtimes down to <1s (easy case) and <10s (hard case).

#hyperfocus is bad enough, but I'm also much happier when I'm hyperfocusing
I can't even tell myself that One Day This Will Be Professionally Useful like some other recent focus points (#linearalgebra #dsp #fft #python #kalmanfilter #orbitalmechanics #geometricalgebra #electronics)

A 30-second 2nd stage engine burn takes the spacecraft over orbital velocity, quickly raising the altitude of the #O3bmPOWER payload. In the next hour or so the speed will slowly decrease again, while the altitude will increase significantly.

My #ksp quest is to use it specifically to teach basic-to-intermediate #orbitalmechanics to non-#space #programming people who are tasked with writing code to handle this type of data.
(As a #softwareengineer myself, the arrogance of "i get paid to think logically" and laziness of "just tell me what to write" coders is appalling. You need to understand the problem domain!)

327 followers · 3191 posts · Server hachyderm.ioI'm following a tutorial for the build + launch + controls part but obvs that will go quickly and I can rely on my existing knowledge of #orbitalmechanics (and brain the size of a planet) to get me the rest of the way.
I've crashed four times on this #rocket alone. All in exactly the same way. All while supposedly following the video instructions.

Also the remote site was impressed with the system and now associates my face with it (like our local site does), which isn't fair to the rest of the teem but doesn't hurt me any.
Boss described himself and *his* boss as "10dB happier". It's nice working for other #engineer

I wonder if that's correct. I guess I'm going to run with it for now. I'll use that to calculate a 4G burn time. :D

Hello #fediverse! Time for an #introduction 🚀
poliastro is an #opensource (MIT) pure #Python library for interactive #Astrodynamics and #OrbitalMechanics. It provides a simple and intuitive API, it's fast thanks to #numba, and it handles physical quantities with units thanks to #Astropy.
🌐 Website https://www.poliastro.space/
:github: Source code https://github.com/poliastro/poliastro
We will be posting tips, news about the project, and cool plots. Stay tuned!
