HowTo enable 1Password app to browser connection with Vivaldi
I use 1Password and KeePassXC as password managers (and can recommend both!). Recently, I needed to overcome an issue blocking the 1Password browser plugin from connecting with the 1Password app. As it turned out, the connection was blocked from the 1Password app, because the browser I was using (vivaldi) is not in the official-supported list of 1Password. Since Vivaldi is “more or less” Chromium, it should work nevertheless. After some search, I found the solution here.

HowTo export e-book annotations from Kobo eReaders (on Linux)
Reading is one of my big hobbies. And in the meantime, I also read non-fiction and scientific literature on my Kobo eReader. For me, one important part of reading and learning from non-fiction books is to make annotations. Kobo supports making highlights and annotations in ebooks. But the question is now, how to get them from the eReader for further usage or processing (and of course, on a Linux machine)?

Recover video recordings from Panasonic DVR based on MEIHDFS, BDAV, and RPLS
Therefore, go home to your villages and repair the IT of your families! (Jesus, never) Despite all circumstances, I managed to visit my family this Christmas. And to some extend, it is tradition that I use some of the time at home to repair/update/replace some IT devices of my family.

HowTo build Displaylink driver for OpenSuse Tumbleweed with latest kernel
New laptop, new dock, latest software…great, isn’t it? I always like those “fresh starts” with new hardware and a new setup. Not only because you have cool new hardware, but also, because it’s a possibility to cut off old pigtails. And, you then have best performance and security with latest software… Well, if there wouldn’t be commercial software for hardware drivers. Preamble / The source of the Problem: DisplayLink With my new ThinkPad, I’m using a USB-C dock and therefore planned to connect my external monitors to this dock.

HowTo build Signal Desktop on OpenSuse/Fedora/CentOS
I use, among others, the Signal App as messenger. Of course, I also want to use the advantages of running a client also on my OpenSuse-based Laptop. Sadly, Open Whisper Systems does only provide packages for Ubuntu-based systems…so I need to build it by myself. Following the build instructions for developers, the build will fail due to some incompatibilities in the dependencies (see e.g. here). Due to permanent updates of the app, I’ve to rebuild it once in a while…and here is how:
