Challenge

Johnny gives a party for his IT colleagues and some friends. There’s not much he’s pedantic about. Except three things: he never skips a beer, he writes his diary everyday and he’s a strong advocate of cross-platform software. To store his diary, he uses a secret place in plain sight of his computer, because he shares it with his mom. This night, after talking about interesting things and almost too many beers, he writes into his diary, basically about the new things he learned today during chatting with one of the more experienced colleagues.

Find the diary, and use it to get the flag.
