Why is that? Do you know anything about the history of it?

Yeah, so there's actually two major competitions that are happening regularly in Germany.

And the reason for that is just because the organizers are German.

And it's easier for them to arrange it there in terms of sponsorship and venues and so on.

Hopefully I pronounced that somewhat correct.

I imagine a huge event of nerds.

So how do you use that freedom? How do you travel? Apart
