Getting to know: VVVV

What’s VVVV, I hear you ask. VVVV is a great tool, I reply. VVVV is pretty awesome way to prototype – visually. What does that mean? VVVV is based on nodes and connecting nodes. A node can be a a numeric input, a serial monitor (to connect vvvv with your arduino), a Kinect-Interface (to read what the Microsoft Kinect sees), a button, a DirectX Renderer and more. Sounds fantastic, doesn’t it? Let me tell you what I did with VVVV so far. Continue reading


First Arduino Steps – Selecting Resistors

Today, I learned about Arduino and I am amazed, again. I learned about circuits at the very beginning. After that we connected our simple circuit to an Arduino Leonardo and then we played around with analog and digital I/O. While programming for that little device is nothing extraordinary, learning about circuits (especially resistors and why we need them) is – at least for me. Here’s what caught my attention in particular. Continue reading

[Update] ChromePass Converter

So I decided to switch from Google’s Chrome to Mozilla’s Firefox – primarily because Firefox supports extensions on Android. Transferring most oft Chrome’s contents worked smoothly and without additional tools except for passwords. Passwords required me to use ChromePass which exports passwords from Chrome to XML. Firefox can then import this XML using an extension called Password Exporter. However, their XML formats are not compatible. Hence this converter.

Linux, Ruby and Python

My first encounter with Linux was in the mid 2000s – and it was a terrible one. Why? Because I grew up using only GUIs. With Linux I suddenly was confronted with a sort of mandatory command line. However, once you see how fast things can be done with a command line you really start to like it. And as I got more and more into programming, I thought to myself about giving Linux another chance. That was a good idea! Continue reading
