London often plays second fiddle to Las Vegas, Barcelona, Hannover and more in terms of where the best developer events are held.
We do have DevWeek it's true, but QCon London appears to be one of the better gathering of real developer purists.
You're more likely to hear about emerging use of Scala at QCon that you are of hearing some polished suit blither on about ERP, ALM, APM and any other selection of 3-letter acronym.
Today is the opening block of sessions http://qconlondon.com/
... and in the organisation's own words, "QCon empowers software development by facilitating the spread of knowledge and innovation in the developer community. A practitioner-driven conference, QCon is designed for technical team leads, architects, engineering directors, and project managers who influence innovation in their teams."
There's some good sessions all week, but here's a snapshot of today:
