I am pretty bummed about not being able to go this year but here is the next best thing to being at the Lang.NET symposuim:
This is a list of all of the videos of the talks presented at the symposium. Additionally there was another conference directly after the Lang.NET Symposium called the DSL Developers Conference. I haven’t yet found nice list of videos from the talks at that conference but when I do I’ll be sure to post it. Anyway, this was a great week for language nerds and I plan on saving some money for the event next year.
