My new project is finished. Normally I build websites… This time, I wanted to create something real! :-)
So I drive my Raspberry Pi through my flat… with two continuous servo motors, wheels, wireless power and a smartphone camera control.
Mein neustes Projekt ist fertig. Sonst baue ich Webseiten… Dieses Mal hatte ich Lust auf was Echtes! :-)
Also lasse ich meinen Raspberry Pi durch die Wohnung fahren… mit zwei Servomotoren, Rädern, kabellosem Strom und einer Handy-Kamera-Steuerung.
Ever wanted to develop a web application with an easy to use, yet powerful persistent item storage? Then how do you like this one?
I proudly present the first version of the Portal Application for my website POCZone.net!
POC is for Proof of Concept. The website hosts a bunch of experimental note taking applications. I’m currently rewriting it. The main design goal is to have a platform that handles all the common app requirements, so the apps can focus on what’s important. I had a week of home vacation in December 2017 and I made good progress! So here we go!

Most of my applications are note taking apps — ToDo lists, Kanban boards, diaries, wikis, etc. I discovered, they have a lot in common:
I love programming! And I love to experiment and create new web applications. This is why my website is called POCZone.net (with POC = Proof of Concept).
I’m currently rewriting the entire website and want to take you with me on the journey!
This article serves is an index and links articles with published work! It will be updated to reflect the status of the development. I also outline the next steps.

Have you seen this great TED Talk about how to improve? I found it fantastic!
In his talk, Eduardo Briceño distinguishes between the “Learning Zone” and the “Performance Zone”.
