I'm exhausted. Tired to my bones, I'm clumsy in my sleepiness and put salt in my tea earlier. My brain is like a telephone box in a Guinness World Records attempt, crammed with a thousand writhing ideas fighting for position. Where am I? What happened to me? And was it worth it? The answers, respectively: I'm in Berlin, it was JSConf EU this weekend, and hells yeah - with bells on.
