Drupalcon is tomorrow in Prague, and I'm in the city for the last four days. I am really excited, as this will be my first Drupalcon (but not the last).
For the moment I'm at the Hub Praha, along with many other drupalists, for the second sprint day. Everybody here is working hard to make Drupal 8 awesome!
We are all divided among task teams and working with core. Ain't that amazing?
There is a multilingual sprint, lead by Gábor Hojtsy (that's the one I'm in). A mobile sprint, a configuration sprint, FAPI sprint, testbot sprint, accesibility, UX, twig... You name it! YesCT is leading the team, along with others that I haven't yet met.
If you are coming to Prague then make sure you attend at least one sprint, they are a great chance to meet the people working with Drupal in person. I'll be here, just tweet me @bserem!
