Yesterday I got my vaccine. Finally. Last night and since I’ve been feeling quite under the weather. Slight fever, a pumping headache and general drowsiness seems to be part of the general experience. Tomorrow should be better. update: I got my second dose of vaccination from biontech on 4 august. update: I got my booster shot (moderna) on 4 january 2022 at the very cool ICC in Berlin.…

This section shall contain short explanations about git and/or github in my own words. The official man page is often a little dense in information- at least for me. How to initialize git repository, add files, commit changes and push to existing github repository: echo "# exo-cortex.github.io" >> README.md git init git add README.md git commit -m "first commit" git branch -M main git remote add origin git@github.com:exo-cortex/exo-cortex.github.io.git git push -u origin main …

with the help of this nice explanation I was able to add math-typesetting to my blog. The framework is KaTeX and it supports a variety of LaTeX math typesetting. This enables me to write fomulas like these: $$ z_{i}(t) = (\lambda + i\omega + \gamma |z_{i}(t)|^{2})z_{i}(t) + \sum_{j=0}^{N} \kappa_{i\leftarrow j} e^{i \phi_{i \leftarrow j}}z_{j}(t - \tau_{i\leftarrow j}) $$ It also allows to write math symbols like $\infty$ within text. This is pretty cool for things like $\tfrac{1}{3}$.…

idea: creating sound from pure functions. The most elemental wave-forms are sine functions. the pitch of a tone defined over time. Every sound in nature can be deconstructed into a collection of sine functions. A single sine function can only be deconstructed into itself and is therefor called “pure”. Some years ago I had the idea of constructing “sound emoji” - abstract representations of emotions through sound. The idea was to create short sound of ~1s that can deliver an emotion with the most basic means.…
