Cutting Online TV Recorder videos on Linux with mpv, Celluloid and otr

On Linux, there are only a few tools for decoding and cutting videos that were recorded with Online TV Recorder. otr is one of them. If no cut list is available for a video, otr has to be called manually with cut intervals that were determined beforehand. This post describes how a small Lua script makes it possible to mark the cut intervals while watching the video in mpv or Celluloid, and to cut the video with otr at the press of a key.

Arch Lispy Setup: Installing Arch Linux declaratively with Guile Scheme

How to install Arch Linux without typing the same commands over and over again is a question this blog keeps coming back to. My latest approach was a set of Ansible playbooks. Since then, I went one step further and wrote a dedicated installer: Alise (short for Arch Lispy Setup). Like my Ansible playbooks, it installs Arch Linux remotely via SSH. But instead of YAML files, an installation is described by a short Guile Scheme script.

Using Ansible to install Arch Linux with LUKS and Btrfs

Automating the installation of Arch Linux is an ongoing topic in this blog. In the past, I often used meta packages, but this approach has some drawbacks. So I started trying out Ansible and created some playbooks that enable the automated remote installation of Arch Linux with different flavors: a simple setup (UEFI, an Ext4-formatted system partition, no encryption, no swap) and a more complex setup (UEFI, a Btrfs-formatted system partition with a customizable subvolume structure and, optionally, LUKS encryption and a swap file).

Managing Arch Linux ARM Repositories from x86_64 Systems

I have some custom repositories for Arch Linux packages that I use for packages from AUR and other packages that I created. Recently, I started supporting ARM architectures and thus needed a way to manage (i.e., add/build, update, remove) these packages for ARM architectures as well. One possibility to do so is installing Arch Linux ARM on an ARM device and using it for the management tasks. However, by combining some tools, it's also possible to manage ARM packages from an x86_64 system; even distributed builds via distcc are supported. In this blog post, I explain how this works.

Automating the Installation of Arch Linux Systems

Arch Linux is great because it brings flexibility and gives users control since it's their decision how the system is set up and configured. On the other hand, the standard installation process1 is completely manual, and if the installation needs to be done more often or if multiple machines need to be installed, the process can become cumbersome and annoying. In this post, we will discuss some approaches to make the installation more convenient and easier to repeat.

Wireless freedom – that’s the appealing slogan of OpenWrt, a Linux distribution specifically made for embedded devices such as routers and access points. It gives you full control over what is installed on the device and how it is customized, and it can extend the functional capabilities of your router significantly compared to the vendor's firmware. But the installation can be quite tricky. In this post I want to share some lessons I learned when installing OpenWrt on an Archer C7.
