This year's HACKED event, which is a free-to-attend weekend of intense learning, building and sharing of cool stuff (that's what the website says) has sold out on tickets. Fear not though as the organisers plan to release more batches through June. Whether you're an expert, novice or a developer or designer, everyone is invited to take part (should you manage to get a place, of course).
So where's the event going to be held? At the O2 and the dates are 20 - 21st of July. Head on over to the official website for more details and to see when tickets will be available again.
