What’s the craziest thing that happened to you that involves technology?
The time when a simple failed innocent looking database query started a chain reaction of race conditions exploding in our face. The whole thing was catalyzed by a number of missing error handlers, since 'those particular boundary conditions can never happen, so why worry about it'. Unfortunately the damage was irreversible. That was the day when I learned, that you always have to prepare for the perfectly impossible and expect the unexpected.
How do you see next 5 years in tech?
Through a crystal ball app on my phone. Jokes aside: I don't like to predict things like that. If you asked me 5 years ago I would have said self driving cars but we got a bunch of Instagram filters and Pokemon Go. :) I would still say self driving cars, but we already have an AI painting pretty pictures based on less then pleasing photos and an AI playing Pokemon Go is not that difficult, so I'm gonna go with that as a prediction. It's a safe bet.
What would you tell to your younger self?
Don't waste your time on building boring stuff for boring people with money. Find out what people care about the most, what makes their life difficult, and make it just a tiny bit easier for them. If they like it, make it better, so that their life becomes even easier, and do this until you have made the world a better place in tiny increments. But even if you don't believe me, that you can do this slowly - I know it's hard, we all want to change the world overnight - at least listen to this one advice: DO NOT BUILD THAT SOCIAL NETWORK SITE. I know MySpace sucks, but by the time you'll be done Facebook will be all the rage... (I really do wish I didn't build that social network... what was I thinking?)
