I started to write this blog in the year 2014 and I wrote about 270 articles since then. Even though the topics changed after time, the main topics are still Sysadmin, Programming, Security and HackADay. In the last years I experienced some serious issues with my blog software. Now I refurbished my blog. I am using a static site generator now, so this blog is static only. I had to give up my comment section for that. That’s very sad, but I hope to receive some mails instead. As with the previous design, I created the new one by myself and I kept it very simple and clean. I hope my readers like it.

The Tonibox is a music player for children. They can simply place figures on the box and depending on the figure, a corresponding audio book is then played. I like this concept and since my child loves audio books, I am going to build such a box.
Note: I never had an original Tonibox in my hands. So I don’t know about it’s exact features and also don’t know how it really works. This article simply describes how I would build such a device.

Few days ago the popular content download software “youtube-dl” was taken down by RIAA. They left a notice in the GitHub-Repository that youtube-dl violates copyrights. In my opinion this is a shame. With youtube-dl it was possible to download any content from youtube. That means you were also able to legally download content that was not protected by any content license. If we start to take down youtube-dl because we could also use it to download content illegally, then we should also take down all the browsers. We could also use browsers to illegally download content.

https://soup.io, one of the best “alternative” social media platforms of the entire internet, will shutdown and discontinue. I don’t have a facebook or twitter account, but I really loved that soup.io. I’ll miss it. The following message is from the soup-kitchen:

OpenVPN comes with example-scripts to update /etc/resolv.conf using “resolvconf” or systemd-resolvconf. I don’t use one of them therefore I modified the script so that it simply changes /etc/resolv.conf directly. I placed a variable “IMMUTEABLE” in this script. If IMMUTEABLE is set to 1, this script will change the fileattribute of /etc/resolv.conf to immuteable. In that way it is possible to prevent other programms like dhcp-clients to change /etc/resolv.conf while openvpn is running. I know, it’s a little bit hacky, but it works for me. The full source can be downloaded at github.com.

This year I want to send you merry christmas by creating a blog-entry for a raspberry pi christmas project. The “christmas-machine” displays merry christmas and wishes for the “christkind” on a tft display for the raspberry. It is possible to send christmas wishes using a web applications that can be accessed via wifi. I placed this installation at the coffee-kitchen in the office and it was very nice to see that my colleges had a lot of fun with it.
Blesses for “Brother Patrick” who spent me that wonderful Joy-IT TFT display.
