This post shows how to use a Raspberry Pi to build an audio receiver supporting Bluetooth streaming, AirPlay, Spotify Connect and, UPnP.

There are multiple ways of building ARM docker images and there is not always a need to have an ARM computer or server in place to do so. Using QEMU ARM architecture can also be emulated on a normal AMD64 computer or laptop. Only when having to compile a lot of packages on ARM, the best advice is to not use emulation since it will take forever. Also, it is always important to keep in mind which ARM platform to target, be it armv6l, armv7l or aarch64.

This blog post is the fourth of four posts about restic, a simple, beautiful, and extremely versatile file backup solution. In this post I will show real-life examples on how to recover forgotten snapshots, mounting the whole repository to a server, changing repository encryption password, and self-updating the installed restic version.

This blog post is the third of four posts about restic, a simple, beautiful, and extremely versatile file backup solution. In this post, I will guide you through a very basic setup of restic backup including a self-hosted Minio S3 server.

This blog post is the second of four posts about restic, a simple, beautiful, and extremely versatile file backup solution. I show how restic looks like in action give a brief overview of its core functions such as backing up, handling tasks on the backup repo, finding the right files, and restoring them.

This blog post is the first of four posts about restic, a simple, beautiful, and extremely versatile file backup solution written in Go. It is very easy to install and configure and just works pretty neat out of the box. Even though restic backup is not for everyone, I quickly fell in love with its simplicity and enjoy the peace of mind it gives me when using it for backing up my Linux servers.

This blog post is about my findings from my personal transition from Bash to Zsh and describes how I got auto-completion for some small tools such as SSH config files and Git to work correctly and how I gave my new Zsh the look and feel of a modern shell using starship cross-shell prompt.

What is nix?
Nix is a package manager for Linux and other Unix systems aiming to manage packages reliably and reproducibly. In order to do so, it introduces Nix expressions, a functional language to build the packages. To increase reproducibility, a package description includes every step to build a package from source. This means that not only the wanted software but also all its dependencies are built from scratch. Therefore, a complete dependency chain can be ensured, which makes the package build process truly reproducible.
