A Rust library and CLI tool for encoding 128-bit numbers as memorable natural language sentences.

An idea, I had a couple of years ago. Somehow I remembered it and was able to implement it with the help of several AIs basically in a day.

At the end of a vibe coding session with goose for fun, google gemini 2.0 flash admitted:

```
I am not able to do it and I am in a loop
I apologize and end the process as I am not competent enough to solve this task
```

Claude sonnet 3.7 generally does better, exceeded by gemini 2.5-pro-exp-03-25, but that one has still too many rate limits.

Dear fediverse, maybe you know the trick. I have a laptop with a `de` keyboard and an external `us` keyboard. How do I configure my system to use either layout depending on the key press source? It's 2024 .. there must be a way! This should work on the console and in wayland gnome (no X11). I know this might be complicated, but not impossible.

Wow! I didn't know Forgejo could host containers! So, I added an action runner with 20 lines of nix and created a project, which builds an action runner image based on nix. This project then uses its own action runner to upload new versions of the runner container.
#Forgejo and #nix make self-hosting so easy! 😍

if you need to run a nix shell with multiple packages included like this:

$ nix shell nixpkgs#foo nixpkgs#bar

then it can be shorter to write

$ nix shell -f flake:nixpkgs foo bar

Yesterday I learned about the #nix config [tarball-ttl](https://nixos.org/manual/nix/stable/command-ref/conf-file.html#conf-tarball-ttl). This explains the oddities I experienced with remote git flake references. If you change your git repo, it then takes 1h to be picked up again. Remind myself to use the `--refresh` option in every fast paced development cycle.

@pid_eins gave a talk about gummiboot... err.. systemd-boot, sd-stub, kernel-install, which Kay Sievers and me wrote aeons ago. It was nicely extended over the years and a lot of infrastructure around it was built to make it a solid boot experience.

Although restic is a really nice backup solution, it lacks the possibility to pull the files to backup from a remote server, like rsync does over ssh, preventing any attacker to gain access to a secret. This blog post shows some workarounds and does the backup to a QNAP NAS S3 store over an encrypted TLS connection.
