Hosting Static Sites with Traefik and Static Web Server Traefik is amazing to host complex services like with containers. On the other hand it’s harder than you’d think to host a simple static html site. I wanted to share my current approach that is based on Static Web Server Project.
Static Web Server (SWS) Static Web Server (or SWS abbreviated) is a simple and really fast web server with the goal to serve static web files or assets.
This article is about monitoring some IoT devices (e.g. a CO2 sensor) with a combination of Mosquitto (a MQTT broker), Telegraf (a metric collector), InfluxDB (a time-series database) and Grafana (for displaying everything nicely). All mentioned services should run on a server that can be reached from the monitoring device(s) and your PC where you want to check the data. We will use MASH (see below) to deploy the services.
Use Case You have one (or more) servers at a hosting provider and a raspberry pi at home. You want to have an offsite backup of the websites, apps and databases at home.
Prerequesits You configure your raspberry pi to be reachable from the internet using DynDNS. In the following we assume that it is reachable at offsite.example.com.
Preparing your backup raspberry pi We want to make sure that backups on the raspberry pi can come from multiple sources and one source can not delete another.
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)
Although physical meetings are not possible, many groups and organizations are dependent on multilingual meetings. In videoconferencing, concepts such as a whispered translation are not intuitive. Therefore a friend and I have developed a concept for translation in videoconferencing. The concept was planned for a conference with 80 participants who will discuss and make decisions over two days either in large groups or in sub-groups. The videoconferencing software that was used was BigBlueButton (BBB).
