I had some IoT devices that I wanted to integrate in my monitoring. For this I set up a MQTT broker as the MQTT protocol is a simple solution to send data from IoT devices to a server. This tutorial is focusing on setting up the server, but I also introduce a Python based MQTT client to test our installation.

On your server, first install mosquitto, our MQTT server/broker.

sudo apt-get install mosquitto

Allow standard mqtt port in firewall (if you have ufw installed)

Auch wenn physische Treffen nicht möglich sind sind viele Gruppen und Organisationen abhängig von mehrsprachigen Treffen. In Videokonferenzen sind Konzepte wie eine Flüsterübersetzung nicht intuitiv umzusetzen. Ich habe daher mit einer anderen Person zusammen ein Konzept für die Übersetzung in Videokonferenzen erarbeitet. Das Konzept wurde geplant für eine Konferenz mit 80 Teilnehmenden, die über zwei Tage hinweg entweder in großer Gruppe oder in Untergruppen diskutieren und Entscheidungen treffen. Die Videokonferenzsoftware die dabei zum Einsatz kam war BigBlueButton (BBB).

Petition gegen Masernimpfung

Ich habe von einem Freund einen Link zu einer Impfgegner Petition bekommen. Da ich solche Petitionen für hochgefährlich halte habe ich mir Zeit für eine Antwort genommen.

Antwort

Hi, ich habe mir die Petition angeschaut und werde sie nicht unterschreiben - aus verschiedenen Gründen.

In der Petition steht: “Masern sind eine harmlose Kinderkrankheit, wenn sie richtig behandelt werden.” Das stimmt für die Mehrheit. Aber 1 von 1000 erleidet eine Gehirnentzündung und 4-11 von 100.000 gesunden Menschen erkrankt an SSPE das immer tödlich verläuft. (https://link.springer.com/article/10.1007/s11910-020-1023-y)

As you man now I work in a research lab. Nearly everyone in our lab needs to do at least some programming. There are trained software engineers next to people how write their first line of code here. As we produce a lot of code that is only scripts not many people used git or any other version control system. For all the good reasons (some are mentioned in the guide) we everybody to learn git in a way that is tradeoff between good version control and fast development. As most of us work on separate projects there is not so much need to collaborate which is reflected ind this guide as I completely excluded branching and merge conflicts. Yet I hope this will maybe help some learners of git or some people that need to introduce git to others.

ILMO

is my first bigger FOSS-project. It aims at managing small libraries as found in a department of a university. You can finde the project on Github.

History:

I started to create ILMO for the (rather small) library in the study rooms of mediacal engineering. It contains about 300 books, 120 labcoats and safty glasses and some more stuff. As I was in charge of the lends I started to get annoyed by our paper-based solution. Especially when a bunch of people was trying to lend things it took to much time. Also reminding people to return stuff was unnecessary complicated. Therfore I started to programm this library management tool from scratch. I only reused some basic database and session functions. The project is still a field of learning how to do things for me. Nevertheless after about half a year of development and many tests the system went live in Winter 2018. Since then I fill the bugtracker and slowly improve workflows and add functions.
