Re-installing Matrix-Synapse server and migrating data

2022-02-27 15:42:09 +0100

I was running a Matrix-Synapse server on Ubuntu 18.04 LTS and recently noticed that it did not receive any updates anymore. It would not have come as a surprise to me if I had read the release notes. ;-) Unfortunately I could not simply upgrade to Ubuntu 20.04 LTS but had to reinstall the operating system - thus losing all data. Of course I’m running backups but I never actually tried to recover from them… It turned out to be quite easy.

Migrating from Wordpress to Jekyll

2022-02-16 18:31:00 +0100

This blog has seen a couple of Wordpress releases and for a short period was even hosted on Blogger. Since comments are disabled it’s a pretty static website and I found that Wordpress is kind of an overkill. It’s still a great CMS, but really more than I currently require. Also - as it’s very wide spread - security issues are exploited quite often. When I came across Jekyll I wasn’t really intrigued at first, but after a while I thought I’d give it try…

Installing Nextcloud on a Synology NAS system

2022-01-22 16:41:30 +0100

Since my Android of choice “CalyxOS” comes with a neat little backup utility called “Seedvault” which will create encrypted backups to Nextcloud I of course wanted to check this out. As I’m already using Déjà-Dup to store backups of my Linux workstation to a Synology NAS drive I looked into the procedure of installing Nextcloud. Fortunately I found some great howtos which I heavily relied on. So thanks to https://strobelstefan.org/2021/03/19/nextcloud-auf-einem-synology-nas-installieren/ and https://mariushosting.com/how-to-install-nextcloud-on-your-synology-nas/ for writing those guides and what you find here will basically repeat their descriptions - maybe with a few alterations.

Replacing the “Steuerpimpel” of a Dual 626 record player

2021-11-21 19:44:25 +0100

My very first (music) record was played on my father’s Dual 626 record player some 35 years ago. This record player is part of my HiFi equipment since a couple of years now. Though I tend to listen to music via streaming services or my own collection of flac files stored on my Synology NAS I still like to play records. And if I do, I really just listen to the music, it will not just run in the background while I’m doing something else. I like the sound and I’m kind of emotionally attached to most of my records. The Dual 626 to my knowledge was built between 1979 and 1981 so my device probably is around 40 years old. It was and still is a very good record player. Some two years ago I got a new needle and everything worked until last year the tonearm would not automatically move to the start position anymore when trying to play a record - and it would not move back once the record ended. Some googling and the issue was found: the “Steuerpimpel” is likely to have vanished after 40 years…

Using a Yubikey to unlock LUKS encrypted disks (with Debian)

2021-08-04 19:14:07 +0200

In probably most cases encrypting the local filesystem might not really be required. However once you tend to take your notebook with you to all kinds of places - i.e. on vacations - it might be good idea to do that. You’ll gain quite some security. But as always you will trade in some convenience - especially if you take it seriously and use a really long password (which you should!). To avoid typing that really long password (and remembering it) at each boot you can simply add 2FA by using a Yubikey.

Adding a Yubikey as second factor is not really complicated but every time I’ve set this up I had to search for suitable instructions again. So I will just sum up how it works - at least for Debian 10 and 11 - here. I will also link to the original instructions I found.
