You have an uncle in prague, the capital city of the czech republic, a formerly communist society. he's invited you to visit for two weeks with your family. you know nothing about prague. what can you do to learn about the culture?

I believe the answer is: 
- Look, listen and think while you're there
- Ask questions when you can

Since communism had a really bad reputation in the past, information that you can find online regarding the culture of ex-communist countries tend to be either biased or exaggerated. The best way to learn about their culture is by keeping an open mind and experience it directly.
