Blog moved
TL;DR it's now at https://cvonderstein.de.
I finally decided to no longer use Ghost as platform to host my blog, but instead use Jekyll again, since it seems that I finally found a solution of deploying it without having to deal with broken Ruby stuff every other week.
At the same time, I decided to finally do something more with my personal domain cvonderstein.de, to which I now moved this blog (and the few contents that were on here). I also plan to become a bit more active in the future in terms of writing blog posts, but we'll see where that goes.
