Library Mannheim – Wednesday, 19. Oktober 2022, 5pm to 6:30pm (17:00 – 18:30 Uhr) Surveillance capitalism is omnipresent. Facebook, Google and others collect data that tell us who we are, what our habits are, what we want and dream of. This intimate knowledge about us only serves to sell us more products and let us consume more than we need and our environment can bear. Arvid Ortwig wants to show ways to tame the smartphone without sacrificing comfort. Speaker Info: Arvid Ortwig has been an IT professional for over 20 years and works as an IT manager in a medium-sized...

If you are familiar with MacOS you probably have come across the “Spotlight” search or even its more powerful siblings Alfred or Raycast. All of them provide search-functionality and launch applications through a little searchbar that pops up once you press a shortcut. Usually Ctrl+Space oder Command+Space. The tool “Ulauncher” is similar to Raycast with the option to launch applications, search for files, open websites with shortcuts or even extend its functionality with extensions. For example search bitwarden for passwords, paste text-snippets (I am prefering Autokey though) start VMs or a Remmina-Session. I can highly recommend that app and hope...

The plugin AutomaticShutdown (https://plugins.octoprint.org/plugins/automaticshutdown/) is great if you want to turn off your Printer after your print is finished. In my case I have the Octopi, the printer and a LED-lamp attached to a Fritz!Dect 200 remote controlled powersocket and configured it to turn itself off when the powerconsumption sinks below 12 Watts for 5 Minutes. So if the print is finished the autoshutdown-plugin shuts down the OctoPi. The socket detects the lower powerconsumption and shuts off itself off after the specified time… Save some energy here…

Matrix is an open standard and communication protocol for real-time communication. In short: something like Signal, Threema or WhatsApp. With one exception: while the former are centrally managed via a company Matrix Servers are federated: Everybody can run a Matrix server. Furthermore every server is able to communicate with any other matrix server. Like e-mail servers. Signal cannot (yet) talk the Threema and vice versa. Matrix has even been chosen by the german army to be there messenger of choice for obvious reasons: The army can run their own servers and is independent from others running servers for them (that...

On the open source social network Mastodon I am following gnulinux.ch who brings up interesting news all around GNU/Linux. So gnulinux.ch has recently posted news about a release of the MotionEye Software which is a web-based frontend for motion. Usually motionEye and motion are used to record videostreams when motion is detected on one of the attached cameras. This is especially useful for security and surveillance cameras but I wanted to simply use MotionEye to show a videostream on a Website vor app and use it for a better version of my babycam v.1 and babycam v.2 MotionEye is using...
