Just some small info, not really a guide, just letting you know I recently learned that there are Wikipedia Database Dumps and the whole english wikipedia including images is only around 110GB, thats as much as the newly released games lol.

Why would you want to replace these utils in the first place?

So why did I switch away from Thunderbird?

Since I ocassionally need tools for math to check my own solutions etc, e.g. for inverting a matrix etc.

Recently Microsoft, the owner of github announced, they would scan and use all projects they have for ai training (source: github docs, march 2026).

# Building a Sudoku Solver (Idea) Basically to solve any game via code, you just take the rules a human would play and implement code that performs them one after another …

The blog is currently kinda quiet, thats due me preparing for exams now + some random coding projects and some other random stuff in my life. the next post will probably happen somewhere between 10-15.

This diagram is rendered during hugo build and served as a static svg.

Singular Value Decomposition allows factorisising an arbitrary matrix (real or complex), while a lot of other matrix factorization like with diagonalising etc. has often contraints.

Why you want this?

A small tool running with no persistent storage, so you can clear everything via reboot (intendet).

At the time I still used discord, I once wrote this incomplete (but cool looking) Discord Bot Client.

A browser extension I once wrote that allows redirecting from one site to another one, following user specified rules.

A minecraft dashboard I once created, it uses rust to launch the minecraft jar, and send inputs via websockets.

I’m still learning Nix(OS), and since it was kinda overwhelming to just deploy a full big config I don’t really understand and have an overview over, I started my own one, that I’m expanding step by step.

this project is just for fun and nothing serious, use it at your own risk # Currently Implemented Commands init ls-tree cat-file cat file can also be used to print trees (like ls-tree) hash-object (-w) log checkout (<file/folder>) if checkout is used with…

I just run: al <name for the alias> and get a new mail redirecting all mails to my main inbox. # Why?

# Before & After Python oneorzero.py copy import random print(random.randint(0, 1)) # Motivation I often need codeblocks in my posts, but it’s rather inconvenient for anyone following the steps, that until now one couldn’t copy the commands right away.

# What is RSS?

This website is a static hugo blog, served by a caddy server.

I currently use Caddy for the statically generated Hugo Blog, since Caddy seems like a robust webserver written in go (so memory safe) and rather fast.

Blog's favicon I made it myself, in the beginning I wanted it to look like a cat, but I failed miserably, so I changed it into a demonic kitty ...

Currently Noctalia v5 is still in the alpha, but I still decided to adapt already, as it works better with my current setup.

An impermanent NixOS Setup is something, I personally I really enjoy, as I don’t like preserving everything on my system forever … Persistence Opt-In is the best approach.
