Ask an expert a question and win a Highload ticket!

This week in Moscow will be one of the best technology conferences HighLoad 2014 .
We want to give the opportunity to "jump on the outgoing train" to those who really wanted to get to the conference, but did not have time or could not buy a ticket. Badoo gives 2 tickets to the conference for the best questions to the experts, which you leave in the comments.
Questions should be on a topic that experts understand, plus they should be complex and interesting.
Ideally, you are talking about some kind of difficulty that you encountered in your work, how you solved it and why it didn’t work out + ask for advice. You can ask any number of questions.
We will summarize the results tomorrow, October 30, at 16-00.
