Hey, let’s take part! It’s all for free!

Let's say, I have apples. A lot of apples. And I want to have a pear. What would I do? I would look out for someone who has a lot of pears and then trade an apple for a pear. This concept works fine, as long as the opposite is actually interested in my apples. But what if the my trading partner is actually looking for bananas? This makes the situation a bit more complex.

The solution to this would be, that you introduce some kind of "medium" that just bears value but other than that, there is nothing more to it. We've done it, we call it "money".

We-Make-Open -Source-Not-Money

The Take Away Festival in the Node London context once more showed up, how closely software development, media and arts are connected to each other.

For many people, at the first glance, there may not seem to be an intermediate connection between those industries - particularly not between software development and arts.
