I was in Amsterdam at DPC and did two workshops, one on the Symfony CMF and another on Http caching with Varnish. I also did a regular talk to introduce to Http caching. The Varnish workshop and talk I did together with David de Boer, who is co-authoring the FOSHttpCache and -Bundle with me.
Additionally, before the conference I went to Leeuwarden to present the CMF at a meetup of the PHP Friesland user group.
