It gives you a clean, temporary, and mostly isolated environment that helps protect your host system. This is useful when you are testing scripts, trying unfamiliar software, or doing some web browsing in an ephemeral environment.https://blog.cmmx.de/2026/03/09/open-a-tab-in-an-existing-yazi-instance/Mon, 09 Mar 2026 12:29:09 +0000blog@cmmx.de (Claus Malter)https://blog.cmmx.de/2026/03/09/open-a-tab-in-an-existing-yazi-instance/Recently I have been trying to switch to a terminal only workflow. I am doing this partly for fun, but honestly the terminal is the fastest way to work with a computer once you get the hang of it. Because of this shift I am using Yazi [1].https://blog.cmmx.de/2026/02/17/encrypting-proxmox-vm-storage/Tue, 17 Feb 2026 13:51:12 +0000blog@cmmx.de (Claus Malter)https://blog.cmmx.de/2026/02/17/encrypting-proxmox-vm-storage/I used to run a dedicated root server with a fully encrypted Proxmox installation. On boot, a dropbear SSH instance listens, waiting for me to unlock the disks before the actual OS loaded. It worked, but the monthly costs started to annoy me.https://blog.cmmx.de/2026/01/25/ssh-agent-forwarding-a-facepalm-moment/Sun, 25 Jan 2026 16:22:00 +0000blog@cmmx.de (Claus Malter)https://blog.cmmx.de/2026/01/25/ssh-agent-forwarding-a-facepalm-moment/I have been using SSH keys for nearly two decades. You would think I’d have the basics fully figured out by now.

It has been a wild ride, and like many of you, I jumped headfirst into the world of “Vibe Coding.” However, after several months of riding that wave, I have realized that this euphoria comes with a significant downside.https://blog.cmmx.de/2026/01/13/taking-control-of-my-dotfiles-with-chezmoi/Tue, 13 Jan 2026 09:42:00 +0000blog@cmmx.de (Claus Malter)https://blog.cmmx.de/2026/01/13/taking-control-of-my-dotfiles-with-chezmoi/Managing dotfiles is one of those things that starts as a quick weekend project and slowly evolves into a serious hobby. I’ve spent more hours than I’d like to admit tweaking my terminal colors or perfecting my shell aliases. For a long time, I relied on a complex shell script to handle everything.https://blog.cmmx.de/2026/01/06/my-hugo-workflow-from-markdown-to-live-post/Tue, 06 Jan 2026 08:14:00 +0000blog@cmmx.de (Claus Malter)https://blog.cmmx.de/2026/01/06/my-hugo-workflow-from-markdown-to-live-post/Hugo is a fantastic static site generator. I’ve always appreciated its “no-nonsense” approach: you write in Markdown, it generates static HTML, and there is zero bloat. Because it has no heavy dependencies, you can host it almost anywhere. However, despite my love for the framework, I’ve always found the actual publishing flow a bit tedious.https://blog.cmmx.de/2026/01/03/building-a-service-hub-one-tool-three-ways-to-use-it/Sat, 03 Jan 2026 10:50:51 +0000blog@cmmx.de (Claus Malter)https://blog.cmmx.de/2026/01/03/building-a-service-hub-one-tool-three-ways-to-use-it/I’ve been wrestling with a common dilemma lately: what’s the best way to build a tool when you need to access it from completely different environments? Take my YouTube transcript downloader, for example. I don’t use it in just one way.https://blog.cmmx.de/2025/12/29/the-fear-of-writing-on-my-own-blog/Mon, 29 Dec 2025 08:45:46 +0000blog@cmmx.de (Claus Malter)https://blog.cmmx.de/2025/12/29/the-fear-of-writing-on-my-own-blog/I have always loved technical blogs. There is something admirable about people who possess the creativity, discipline, and knowledge to regularly publish content. Looking at my RSS feed, I often envy the writers who seem to effortlessly share their wisdom with the world.https://blog.cmmx.de/2025/12/25/self-hosting-pangolin-a-minimal-setup-guide/Thu, 25 Dec 2025 09:33:24 +0000blog@cmmx.de (Claus Malter)https://blog.cmmx.de/2025/12/25/self-hosting-pangolin-a-minimal-setup-guide/Pangolin is a powerful self-hosted platform for managing secure, zero-trust network access to your services. I switched from Cloudflare to Pangolin primarily due to (free-tier) limitations and performance issues. Also, I encountered consistent connectivity problems during peak hours, particularly in the evenings, caused by Telekom’s peer routing policies.https://blog.cmmx.de/2025/12/22/my-personal-ai-recap-of-2025-part-1/Mon, 22 Dec 2025 16:02:17 +0000blog@cmmx.de (Claus Malter)https://blog.cmmx.de/2025/12/22/my-personal-ai-recap-of-2025-part-1/2025 was one of the most transformative years for me since the COVID-19 pandemic and the year I became a father. It marked the rise of “Vibe Coding” and agentic workflows, opening up previously unimaginable possibilities. For me, it all began in early 2025 as I started to realize just how effective Vibe Coding could be.https://blog.cmmx.de/bookmarks/bookmark-20251110/Mon, 10 Nov 2025 19:36:28 +0100blog@cmmx.de (Claus Malter)https://blog.cmmx.de/bookmarks/bookmark-20251110/I’m fascinated by how code becomes music. https://strudel.cc/workshop/getting-started/ Strudel is a music live coding environment for the browser, porting the TidalCycles pattern language to JavaScript.https://blog.cmmx.de/bookmarks/bookmark-20250919/Fri, 19 Sep 2025 06:59:41 +0200blog@cmmx.de (Claus Malter)https://blog.cmmx.de/bookmarks/bookmark-20250919/https://www.paxhistoria.co/ For a Europa Universalis 4 player, this AI based strategy game feels like a dream come true.https://blog.cmmx.de/2025/08/27/secure-your-environment-files-with-git-sops-and-age/Wed, 27 Aug 2025 08:00:17 +0000blog@cmmx.de (Claus Malter)https://blog.cmmx.de/2025/08/27/secure-your-environment-files-with-git-sops-and-age/Managing secrets in code is challenging.

Most of you know what virtual desktops are, so here is only a short explanation: Virtual desktops are a software feature that allows you to organize and manage multiple desktop environments on a single computer.https://blog.cmmx.de/2024/12/29/kopia-a-new-player-on-the-backup-field/Sun, 29 Dec 2024 12:00:17 +0000blog@cmmx.de (Claus Malter)https://blog.cmmx.de/2024/12/29/kopia-a-new-player-on-the-backup-field/I love backups. Most people who know me probably know that. And I love borgbackup [1]. I’ve been using borgbackup for many years and I still think it’s the best backup tool in the open source world.
