Tmux Popup Windows

Fri, 24 Apr 2026 21:11:19 +0200

Your browser does not support the video tag.

The video shows a tmux session with a couple of windows and the current window with 3 panes. Then suddenly a popup window opens in the center. It opens with ncmpcpp - the ncurses media player plus plus. The playlist is opened and then a different track gets selected and started. Afterwards it just disappears.

A simple and neat feature of tmux is popup windows! I only discovered them recently. They’re just floating windows that open above the regular windows and panes. Once opened, it takes focus, so you cannot interact in the panes or windows below. Switching windows is also not possible until a popup window exists. These are meant for quick tasks, like for example opening an mpd client to run a command,close the window (by hitting q) and go on with whatever you’ve been doing.

SSH Host Aliases in Git Remotes

Sat, 31 Jan 2026 14:44:15 +0100

Today I learned…

that you can use SSH host aliases in git remote URLs!

First of all, here is my problem and use case:
I want to be able to have multiple remotes in a local git repo with different logins and of course different SSH keys, because I use one pair of SSH keys per connection. For repositories with only one remote I used to set core.sshCommand. This applies to every remote you configure. You could use the GIT_SSH_COMMAND environment variable on the command line to overwrite the core.sshCommand setting, because it would be prioritized. This could be done by writing it on the command line manually, or by using a shell alias, or git alias. None of these options are really practical in everyday use.

Debian on encrypted LVM with btrfs subvolumes

A simple tutorial on installing Debian on an encrypted LVM with btrfs and subvolumes :-)

There are plenty tutorials out there already and I used to mix several methods to create my way of the process. This blog post is a kind note for myself. My recipe for something that fits and that I can read and use when I need it – but shared so that others can use it as wels :-)

Obsidian Synchronisation iOS Linux

Wed, 18 Jun 2025 22:21:32 +0100

Bisher habe die files in meinem Obsidian zwischen iPhone und meinem Linux Desktop per Git synchronisiert. Das funktioniert zuverlässig, aber Bedürfnisse ändern sich ja schon mal und ich wollte eine schnellere und bequemere Methode.

Ein Bekannter von mir nutzt dafür den Obsidian-livesync service. Dieser wird mit CouchDB betrieben und nur dafür wollte ich das nicht installieren und überlegte erstmal weiter. Da ich auch eine Nextcloud habe, suchte ich in den community plugins von Obsidian nach WebDAV und fand das remotely-safe plugin. Zuerst richtete ich ein neues vault zum Testen ein und installierte das plugin. In den Einstellungen habe ich den login-Namen, das app-Passwort, das ich hiefür generiert habe und die URL nach folgendem Schema hinterlegt:

Launch Appimages using rofi

Mon, 30 Dec 2024 21:58:47 +0100

I’m using rofi as application launcher on my linux desktop systems and since I’m using AppImages as well I also wanted to know how I can easily launch them via rofi. I always thought that I had to extend rofi’s search path, but I haven’t found a solution yet. Today I found out that .desktop files per application integrate them into the menu. Thank you til.scapegoat.dev for your article about it! I knew that .desktop files existed, but I have never used them myself. Now I know these are to create shortcut icons on desktops, or to create system menu entries and submenus.
