My tip today is .NET Rocks episode 1038, Node and sails.js with Mike Hostetler, length 52:31.
Node seems to be growing in popularity and even though I still haven’t looked into it too much it looks cool and I know I’ll have it in my projects soon.
Mike talk about his work with Node and with Sails.js which is an MVC framework that help you build well-structured web pages in JavaScript against Node on the backend.
