I've been much slower than I intended on getting the speaker line-up (published last week) and the talk details (still working on this...!) published, sorry about this :/
To make up for it, I've pushed back the deadline for early bird tickets until 1st July, so that people can see more details fo the line-up and still have the opportunity to get the cheaper tickets.
Again, apologies for keeping you waiting on the talk details; more details are on their way, I swear!
Early bird tickets cost £180, regular tickets would cost £240.
