Whoah, this conference just keeps getting bigger and better. The organizers counted about 1200 people just in the first day. I remember attending about 5-6 years ago, there were about 120 people in total. Also, check out my post from last year’s DevConfCZ.

Just check out the #DevConfCZ Twitter hashtag for proof. Also, the coffee from Kofi Kofi was just amazing.

Several minor problems occured to me during the weekend:

• Lack of recycling trash bins
• 8 parallel sessions, anyone? – during some time slots, I’ve definitely been in need of Hermione’s time turning thing. How can you attend 3 talks at the same time? (Answer: YouTube live stream + archive!)

Here’s a short summary of talks I attended. Most of them you can find in Red Hat’s YouTube channel.
