This blog turned 6 years old. Unbelievable! I would like to thank all the people who read my articles.

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.

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:

Identifier: AIT-SA-20200301-01
Target: Creative Contact Form (for Joomla)
Vendor: Creative Solutions
Version: 4.6.2 (before Dec 03 2019)
CVE: CVE-2020-9364
Accessibility: Remote
Severity: High
Author: Wolfgang Hotwagner (AIT Austrian Institute of Technology)

Summary

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.

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.
