Third, there is math. College level stuff like linear algebra and matrix manipulations. Raquel Velez @rockbot rocked the house with her talk AI.js: Robots with Brains. She is now a contributor to the Johnny-Five library for Arduinos and was a leader for the NodeBots day. One of the talks that generated the most buzz during JSConf was Making WebGL Dance by Steven Wittens. I'm just starting to go through the slides because I was in track B during this talk. (jdalton's performance talk also got buzz.)
Fourth, responsive design took some serious hits. For most people it means one code base using media queries to use different parts of the css or js to produce different layouts. Brian Leroux who is working on Topcoat at Adobe emphasized we may never be at the point that serving one set of files provides the best experience. Adobe open sourced their research. Topcoat has desktop and mobile versions. In DOMkata: The Dark Art of Mobile Web during CSSConf Mike Stamm, WSJ mobile web lead, showed the difficulties determining just browser width.
The day between the talks harkened back to the first JSConfs where the same people sat together all day. This year I was at a table was in the NodeBot event. Every participant (attendee) at JSConf receive an Arduino. Our team built a robot arm that typed "helloworld.js" (second video). My teammates deserve most of the credit: Bryan Hughes, Mike Surowiec and Rahul Ravikumar. Every reason to believe that they will have as much success as my yayQuery tablemates have had. Revived memories of my electrical engineering and breadboarding days. Thanks to Rick Waldron, Raquel Velez, Sarah Chipps and other for leading this.
Other talks were also significant. I missed most of the Track B talks. Also missed several of the CSSConf talks. And a few of the talks were so code heavy that I'll have to sit with the presentations to really understand them like Master the CLI with Node and schema liberation with json and plv8. Thanks to all the presenters who took great efforts to make a presentation.
I am seriously considering leading a JS Journalism Conf in fall 2013. Let me know if you are interested.
