Node.js vs Play Framework by Yevgeniy Brikman (LinkedIn Engineer)
PowerPoint: http://www.slideshare.net/brikis98/nodejs-vs-play-framework (readable by itself)
This is a really good talk if you’re interested in either Node.js or Play Framework. I mess with Play a lot, but I’ve been interested in Node.js lately. It’s very fair comparison, the speaker seems to like both equally. I do think his community rating for Play was a bit high, it’s a pretty small community but I guess all the information you need is out there, I’ve never really had a problem finding it.
