For the past 15 years my "home cinema" setup has been a 55 inch Sony LED TV and an all-in-one Sony 5.1 Surround sound system with integrated Bluray player. Additionally there is a Linux VDR for FTA satellite broadcasts, and a Xiaomi Mibox streaming client.

Digital photography workflows tend to be dominated by a relatively small number of proprietary, commercial software suites that have been optimized over years or even decades. Adobe Lightroom, Capture One, or Affinity Photo are household names, and they're all available for both MacOS as well as Windows. Which also means …

Using Yubikeys for SSH

Posted by fedops in Security   

Something I've been meaning to try for a while was using a physical MFA token in conjunction with SSH to secure connections to remote servers. I've been casually reading blogs on the subject, but it seemed to be a bit of faff surrounding the issue.

Selfhosted Calendaring

Posted by fedops in Software   

I've avoided delving into the calendaring topic for a long while. It seemed a hassle and also I wasn't sure how to best integrate work and private calendars. I don't have very many private appointments anyway, and the ones I do have should ideally also block out the respective times …

Using a Sun Keyboard under Linux

Posted by fedops in Hardware   

I got my start in system administration in the early 1990s, maintaining a university institute full of Sun Microsystems workstations. Those were the late days of the Unix wars, and the main contenders were Digital Equipment Corporation (DEC), Hewlett-Packard (HP), IBM, Silicon Graphics Inc. (SGI), and Sun. Sun were well-loved …

The Personal Landing Page

Posted by fedops in InfoManagement   

It took me a while to come up with a coherent description of the questions that ultimately led to the solution I'm presenting in this post. Which in itself I think is quite straightforward. Bear with me here while I lay out the ideas:

Note Taking and Searching

Posted by fedops in InfoManagement

Installing and Using pandoc on Fedora/Centos/Rocky

Posted by fedops in Howto   

Documentation-As-Code is a much better approach than your WYSIWYG editor of old.

The general consensus regarding how to create and maintain documentation has definitely changed over the past few years. People had come to regard WYSIWYG text processors as the gold standard. Effortlessly arrange text and images, see what you …
