What Is LoRa? A Beginner's Guide #1

IoT is the trend word of recent years and we would like to introduce the terms and technologies behind it on our blog.  We have already written a lot about the connection technology Sigfox. LoRa(WAN) is yet another smart, energy-efficient technology, and in this two-part blog series, we’re going to get to the bottom of the term Lora(WAN) and highlight some of the possible trends that could result from it.

Maker Monday: Measuring Air Pollution on New Year’s Eve with a Particulate Matter Sensor

Here in Germany, fireworks are "unbanned" for one day of the year: New Year's Eve. And every year I wonder how it is possible that fireworks are still legal at all, even for one day. Setting aside the safety factor (mixing drunken revelers with fire and rockets is never, ever a good idea), there is the fact that fireworks are terrible for the environment. Back in 2016, fireworks in Germany accounted for a particulate matter level equivalent to 17% of the country's annual vehicle emissions. And most of that on just one night!

The 4 Biggest Mistakes in My IT Career

Before I decided to mess up Paessler's online marketing team, I spent almost 20 years as an IT admin. At the end of the previous millennium, I enjoyed a classic apprenticeship as an IT administrator (back then, the profession was still called "data processing manager" in Germany). Following that, I worked for many years in an IT system house and later in the internal IT department of an automotive supplier.

10 Essential Apps That Make Your Sysadmin Life Easier

Over a year ago, we asked our very own Paessler admins which mobile apps they could not live without. So now we decided to expand this survey and give you a little overview on what your fellow sysadmins are using. To do this, we ventured into the depths of Reddit, and as we got a lot of feedback, here’s a roundup.

Quantum Computers: What They Can (and What They Can Not Do)

In my first article about quantum computers I explained the rudimentary principles. Now it gets a bit more concrete and practical. If you haven't read the first article yet, it would make sense to do so here before continuing.

IT Monitoring with an Open Source or a Commercial Solution? It's More Than a Question of Money.

Hardly any company can do without comprehensive IT monitoring. But when choosing the right solution, the question often arises whether an IT administrator should work with freeware or an open source option, or whether a commercial solution should be bought. Just to be clear: No IT company and almost no IT product can do completely without open source. We use it constantly and therefore we are not questioning the value of open source. But does monitoring with an open source solution make sense, is it as cost-effective as alleged, and as individually configurable as sometimes claimed? We get to the bottom of it.

The End of the Anonymous Hacker?

We recently gave an outlook on the impact Artificial Intelligence can have on our future. In addition, there are of course specific effects for each individual profession. And if you define illegal hacking as a profession, then there too. Because just like righteous programmers, hackers usually leave their very own mark in the programs and code they write. And surprise: AI can easily find clues that expose a hacker faster than they would like.

4 Ways to Shape the Future: Lessons from the Web Summit
