The problem I want to use Pylint in Neovim, and I want to use a standard installation that is directly managed by Neovim. Hence I have installed Mason and used Mason to install Pylint. Now this is a problem when working with virtual environments: Pylint searches the packages in their own virtual environment (which is now managed by Mason and hidden somewhere in nvim’s storage) and does not understand my local imports. ...
We are storing configurations. Let’s assume we are working on a store and we want to save prices for different products. But there are a set of configurations we have to consider1: We are working over multiple countries. Every country has got some locations. Every location has a set of articles. For an article, I might have multiple sizes. Finally, for every size I have got prices. Now let’s say that we want to store all of that in a Python dictionary.

In commercial rounding, this “$0.5$” problem is solved by “rounding away from zero”, meaning: For positive numbers, round up; for negative numbers, round down. This makes perfect sense for a mathematician, but others might need examples, so here are some1: ...
I finally managed to setup a Footer Menu. This was not too complex, for some things one just has to find the time… But I did learn one CSS thing, namely justify-content: center. The remaining work was not too exciting.

During the latest changes on my Blog, I also updated the version of PaperMod. I now discovered a bug that PaperMod introduced, and I wanted to fix it. The problem was: In the Post metadata line, I typically have a part telling “Translations: De”, as I write most post in both german and english. Now with this commit, this part was broken and the “De” part was moved to the next line. ...
I now can do post series!
