In forests we usually find unpaved roads like this: Now we should observe how they are constructed. Usually the need to somehow allow access to areas in the forest. It does not have to be the shortest connection, it does not have to be as flat as possible, it is not required to build for …
In the old days of the web, more than 20 years ago, we found a possibility to write German Umlaut letters and a lot of other letters and symbols using pure ASCII. These are called „entities„, btw.

It is an interesting trend to create micro components, microservices and use building blocks that are very easy to understand. As always, a new approach will not eliminate all problems. The problem that we are solving has an inherent complexity that we cannot beat. But usually we create a lot of complexity that would not …

Not having explored the music side, I did find the idea of creating images fun and inspiring. It also shows us something about the functions we are working with, if we learn to read …
