December is usually less intensive because of the holidays and the end of the year - mine was quite packed though.
Let's quickly summarize two conferences that happened in Warsaw recently: Code Europe on December 7th and GDG DevFest on December 9th. Both events were confirmed very late and both happened just before I flew to Austin for Mozilla's All Hands.
Last meetup this year was held on Tuesday, November 28th in the same place as usual. It was also the very first one I haven't led personally, because I had laryngitis and couldn't say a word.
As you can imagine in December I wasn't too active because of the inevitable Christmas time - I mostly focused on answering emails to not be swamped by them too much.
There were two cases when I gave two talks in one day, but both were during a single conference - Hungarian Web Conference in Budapest and 4Developers in Warsaw. This time I did two talks at two different venues, although in the same city. I even managed to go for dinner of the first one after the second one ended.
