Hey. I'm interested in the logistics behind hosting such events. How many people were present? Was this just a one-off event or is this a part of a longer workshop? Did everyone bring their own computers or did you provide them for the participants? If people brought their own, how did you deal with the fact that node.js is not pre-installed - was there any introductory period where you gave instructions how to install/configure the environment? If so, did you account for different operating systems? If, on the other hand, you provided the computers, who supplied them? A local library, a school, a private company, yourself? I don't need a specific name, just a rough category. I'm asking, because I'm interested in hosting a similar event, but for a younger crowd. I figured pure JavaScript would be the best choice because you don't need a fancy setup - it works straight in your web browser, no matter the platform. Using something like Python or Ruby (not to mention C++ or Java) would be more difficult to coordinate.
