Over the course of a year I gave a lot of talks because I wanted to learn more about public speaking. One time I gave two different talks in two different countries in less than 24 hours. That was exhausting but also fun!
I gave all kinds of talks, about dynamic programming and optimization, about functional programming, about building a shell, about engineering culture, and about Etsy's infrastructure. If you want to speak more too, I recommend techspeakdigest and WriteSpeakCode.
At StrangeLoop in St. Louis, Missouri, and also at BoBKonf in Berlin.
At JSConf EU in Berlin, Germany. Also at FluentConf in San Francisco, at BerlinJS, and closing talk at FullStackFest in Barcelona, Spain.
At Nightlybuild.io in Cologne, Germany. Also at Re:publica in Berlin, at Chaos Communication Camp in Brandenburg, and FrOSCon in Bonn.
At Enthusiasticon in Berlin / Wikimedia Deutschland. I also made a 5 minute version for Etsy's ignite.
At QCon New York, video on InfoQ. Also at CodeAsCraft:RecurseCenter in Brooklyn, and at International PHP Conference in Munich.
At Berlin Buzzwords, Berlin, Germany.
At Radical Networks in NYC, at Blackhoodie St. Pölten, Austria.
