Juliasim Model Optimizer

JuliaSim is a cloud-hosted platform for physical simulation. It combines a vast array of bleeding edge SciML techniques, acausal equation-based digital twin modeling and simulation and is powered by the Julia programming language. It is preview-only software in the time of writing this post (December 2022). JuliaSim produces surrogates of blackbox (and regular) dynamical systems using Continuous Time Echo State Networks 1. This technique allows, amongst other features, for implicit training in parameter space to stabilize the ill-conditioning present in stiff systems....

Esa Design Booster

The Fly Your Satellite! Design Booster is a pilot program of the European Space Agency (ESA). It’s aimed at students working in the design of a CubeSat mission. CubeSats are miniaturized satellites that have standardized form — in LEGO brick fashion, they’re shaped as $n \ge 1$ 10cm cubes, stacked vertically. It’s an idea to accelerate and democratize space missions1, cutting down on the cost2 and effort required to get the spacecraft in-orbit....

Second Brain

Besides a notebook, everything else happens in a single Obsidian vault. Note that I’m writing things for myself by default, disregarding the audience — this won’t make much sense. If you want it to make more sense, start with the resources first, they’re ordered. I want to transition to sketchnoting, hopefully accumulating a vocabulary of atomic, small drawings that I can use in a modular fashion. If you want an even more structured way to make sense of all of this, I recommend you start with The First Principles of Visual Note-Taking - YouTube and then Mind mapping with Excalidraw-Obsidian - YouTube and Part 1 Building a Second Brain Book on a Page - YouTube....
