10 years to transform the future of humanity — or destabilize the planet (TED talk)

„We are forced to consider the real risk of destabilizing the entire planet“ says Johan Rockström, director of the Potsdam Institute for Climate Impact Research.

Learn about the planetary boundaries and why the climate tipping points are something to be concerned about.

He also says: „The good news is: We can do this. We have the knowledge. We have the technology.“

So. Let‘s start moving!

Wie funktioniert der Treibhauseffekt? (in 3 Minuten)

Warum ist es ein Problem, wenn wir zu dem winzigen 0,028% Anteil von CO2 in der Luft noch ein paar Hunderstel Prozent CO2 hinzufügen? Wie kann so ein bisschen Gas unsere Welt ins Wanken bringen?

Es ist wichtig, dass wir alle verstehen, dass es sich dabei nicht um eine fixe Idee von ein paar Schülern handelt, sondern um wissenschaftlich fundierte Erkenntnisse, die schon über 100 Jahre bekannt sind. In diesem Blogpost möchte ich also etwas Grundlegendes zum Treibhauseffekt schreiben.

My Fridays-for-Future project: Monitoring the CO₂ in the atmosphere to stay aware of Earth’s most important metric

Today thousands of students of the Fridays-for-Future movement are on strike. They protest for more aggressive action against climate change. Formally I am not a student anymore, but I consider myself a life-long learner and student of life as well. So here is my student-contribution for global awareness of the CO₂ crisis.

Comparison: Seven devices between €69 and €500 for monitoring environmental parameters like temperature and humidity with PRTG

As the founder of “The network monitoring company” Paessler AG it came quite natural to me to not only monitor our home network but also various environmental metrics in our family home. We had moved into our new home a year and a half ago and having temperature data series has been quite helpful to do the fine tuning and bug-fixing of the heating and venting systems.

I am not so much a maker person like my colleagues who built their own smart thermometers for our office building. I like to use prefabricated devices. So I ordered 6 different out-of-the-box devices (mostly from Amazon) to monitor temperatures etc. in our house. I connected all these sensors to my PRTG installation which also monitors the heating system and solar panels via ModbusTCP and many other systems of the house.

Here is an overview of the sensor devices I am using:

This is my favorite free weather outlook widget for my dashboards

With PRTG I can do “live” monitoring of things, e.g. environmental stuff like the current sunlight (solar panels), my heating system and temperatures throughout the building. I also wanted to add a look into the future so I looked around for a html widget to display the weather outlook that I could add to my PRTG maps.

What to do when Teamviewer goes offline as the PC goes into “connected standby” mode

The power saving feature “connected standby” of Windows 10 causes PCs to go offline from Teamviewer, so you can’t wake them up and connect/control them. But there is a trick that stops this behavior.
