Software created in Germany never had the same flavour as cars. It's actually more of a smell. And this smell is gradually leaking into the other products. But what can we do to change that? I have three ideas.

Creating a custom element for a demo todo list in a test driven fashion, using jest, dom-testing-tools, LitElement and pure-lit.

What if someone told you that by adding another package to your lit-element project, you will create smaller bundles and write less code?

Testing your bash scripts ain't easy. As testing their unit is tricky by design, I searched for something to test their behaviour and looked at BDD for the terminal.

Javascript errors for you users might get lost if you don't log them. This post is showing a very easy way to get to them, without requiring users to call you on the phone.

I've forgotten more about javascript frameworks than most people learned about. Most frameworks were working around shortcomings of HTML and javascript at that time. Web components are a set of tools to remove a lot of those shortcomings, so let's take a look at them.

Technology moves on. And my website fell behind. Without any visible changes, I replaced 1MB Javascript with 700 Byte, replacing jQuery Plugins with CSS.

Our kids are birthday-wise pretty close, and only one year apart. Wouldn't it be a great idea to combine the parties? In hindsight, it was a pretty bad idea inviting so many kids at once, but at least we build some bristlebots.

There comes the moment in every's Arduino programmer life when 1 LED is not enough. As always, the next feasible step from one is 60, but controlling a set of red, green and blue LEDs to represent the 8bit color array is slightly more difficult then one would expect.

In a desperate attempt to prove my kids our robomover is stupid we collaboratively created an indoor version with an arduino. This is when I learned that kids are too noisy for ultrasonic sensors.

I'm playing around with software since I was 8, and was lucky enough to make this hobby my work.
I was founder of two companies, and worked with some german and international companies as Software Developer and Manager, most notably Microsoft, AutoScout24 and 1&1.
I'm a dreamer, who loves to dive into a chaotic, complex environment finding the best way to optimize the system. I'm a coach, helping people to develop themselves, and work in a group. I'm a manager, who is striving to create teams that do not require his management. I'm a developer, who loves to write code and make the world a little easier. I'm a dreamer, hoping to improve the world.
Also I'm into sport, married with children and love my life.
I'm a regular speaker on conferences in Germany, mostly around the topics organizational development, agile and teambuilding (i.e. in 2017 on the ScrumDay) and successful DevOps and agile implementations using bottom-up change processes (i.e. in 2017 DevOpsCon and XP-Days). I published the article “Reinvent your workplace” in the iX in 2016 with a collegue at 1&1 following a talk on the continuous lifecycle conference around how to change a department in both technical and organizational dimension.
