I attended Chemnitzer Linuxtage 2025 from Friday, March 21st to Sunday, March 23rd. It was my second time at the event, and I enjoyed it even more than last year. This time, approximately 3,500 people attended in person, with up to 250 parallel viewers joining the live streaming of lectures. You can find more details in the official blog post .

Live Talks

I had the opportunity to attend several fascinating talks in person:

Recorded Sessions

In addition to the live talks, I caught up with several recorded sessions on media.ccc.de:

  • Kleine Bash-Tricks - This session introduced various Bash shortcuts and techniques. One highlight was learning about Alt+., which recalls the last parameter from the previous command—for example, after running ls /somepath/file, you can type rm followed by Alt+. to quickly add the path and filename.

  • Pimp Your Shell - A comprehensive overview of shell customization options to enhance productivity and user experience.

  • 24 Monate Immutable Desktop: Ein Erfahrungsbericht - Having used immutable desktops for about 18 months myself, I was particularly interested in the speaker’s experiences and perspectives on this approach to desktop management.

  • Infrastruktur und Security Tests - A highly informative session that provided numerous ideas for improving infrastructure testing. I’m especially eager to explore testinfra and Ansible assertions based on the insights shared.

  • Good Practices für Ansible Inventories und Inventar-Daten - An excellent presentation by Henning. I’m looking forward to his follow-up talk, which is scheduled for FrOSCon 2025 in August.

My Contribution

I also had the privilege of presenting a talk titled Effiziente Dotfile-Verwaltung: chezmoi im Einsatz about chezmoi , a tool for managing dotfiles across multiple machines. The audience engagement was encouraging, and I received valuable feedback that will inform my future explorations of the tool.

Conclusion

Chemnitzer Linuxtage 2025 was an enriching experience that exceeded my expectations. The event offered a perfect blend of technical depth and community engagement, providing both practical knowledge and networking opportunities. The diversity of topics covered—from shell optimization to infrastructure security—reflected the vibrant ecosystem of open-source technologies.

As I implement some of the techniques and tools I learned about, I’m already looking forward to returning next year and perhaps contributing more to this wonderful community event.

I use chezmoi for my dotfiles. To find out why and how to get started, check out my talk from Chemnitzer Linuxtage 2025 .

Within chezmoi, you can use the file .chezmoiexternal.toml to download archives or git repositories during updates. This is particularly useful for managing external dependencies. Let me walk you through some common use cases.
