I've never been much of a speaker, not in my native language and even less so in English. When Markus Völter, the man behind SE Radio and omega tau podcasts, contacted me to make a podcast about Outerra and some of the technology behind it, I initially hesitated. But then I decided that it cannot hurt, and that I must force myself to train my tongue a bit.
So, after some time we recorded a hour long interview and you can listen to it here:

Beware that I'm really slow speaker with pretty monotonous voice, and together with the technical nature it's probably not consumable for everyone. Enjoy if you can :-)
