Don't abuse Co-authored-by for marking AI assistance

Instead, use a dedicated AI-assistant: trailer with a more useful format.

Secure and redundant server setup with a bit of lazyness

Step-by-step guide to set up an Ubuntu server with the root partition on btrfs raid1, encrypted with luks, and automatically unlocking on boot via a mandos server running locally.

Git commits and how to craft them

A set of rules, their rationale and a short practical guide to creating useful git commits.

Email in the terminal: a complete guide to the unix way of email

Reading emails in your terminal is fast, highly customizable, productive, and fun. Unfortunately, it can be frustrating to set up. This is a complete guide to take the frustration out of the process.

More keyboard, less mouse: my Regolith + tmux + vim based workflow

Keyboard centric tools: Regolith, tmux and vim + benefits of using text files (markdown and LaTeX with git).

Naming chaos in statistics: bring order by thinking in mathematical models

Ever got confused by difference between the two GLMs? With why ANCOVA and GLM do the same thing? Ever had trouble remembering assumptions? Stop thinking in tests and start thinking in mathematical models, and everything will be much clearer.

Ethorobotics and the first bio-robot

The dog can be considered the first bio-robot “built” by humans, and we’re only slightly joking with that statement. Let’s explore the concept of ethorobotics to understand why.

Why guitar frets work (and why violins don't have them)

Obviously, you squeeze the string to the fret, which shortens the string making a higher sound. But it occurred to me, that it’s awfully convenient that you need one in the same place for all the strings. And if it’s so awfully convenient, how come violinist put up with having to find the exact place to hold the strings, rather then getting frets?

Fastest and smallest way to set up R with jupyter on Windows

This tutorial will show you the fastest (and smallest) install of Jupyter Notebook if you only want to run R with it.

Nothing. 
 Or let’s be precise: not much. Both are things (nodes, vertices) connected by other things (links, edges) and any distinction is pretty much nothing but tradition. 
 My PhD dissertation has a network science part. When I started writing about Erdős-Rényi graphs in this part I realized I had to clear up the relationship between the networks and graphs. After some research I…

 Your robot doesn’t have to behave like a human, for it to be socially acceptable. Your dog and cat doesn’t, and you still love having them around. See more here . I used to lead the development of the Biscee, but now I’m mostly just a consultant.
