Nice writeup of my Webhooks talk from OSCON Europe: http://thenewstack.io/wonderful-world-webhooks/
A talk I gave at CodeMotion in Berlin, covering some databases other than MySQL (spoiler: Postgres, Redis and CouchDB)
There is also a podcast of the presentation audio https://voicerepublic.com/talks/beyond-mysql
Delighted to have given this talk at OSCON Europe in London!
My local user group were kindly my qualified technical audience for rehearsing this talk before Velocity in Amsterdam.
