Ask HN: What are good tech conferences in UK?

I really enjoyed going to the PyCon UK! Everybody was so lovely and really interesting talks. Was of course more python centric

For Java and associated ecosystem, Devoxx UK (http://www.devoxx.co.uk) is a pretty good annual conference. You can see talks from last year at https://www.parleys.com/channel/devoxx-uk-2015

Social Media Summit on in Dublin, Ireland in March. Some good speakers present. http://socialmediasummit.ie/index.php/speakers/

Render-Conf is looking to be good: http://2016.render-conf.com/ It replaces jQueryUK which was great last year.
