Pusher is a new Web service from New Bamboo that makes it easy to push data to users of your web applications "live", outside of the request response cycle. They've embraced Web Sockets technology and built a REST API to which you can post events.

Where’s Waldo is my little node.js/Redis project to keep track of users in an app. Say hi!

Tracking hits on every request can get costly, and I didn’t want to hold up the more important server processes with this. So, it felt like a good fit for a quick asynchronous web server. Node.js and Redis fit the bill perfectly.

Ruby is a highly dynamic language with impressive capabilities for runtime redefinition of classes, objects, methods, and variables. Haskell, on the other hand, is a purely functional language that confines mutation within a sophisticated static type system. Given their many differences one or the other may be more suited for whatever problem you might be working on (see polyglot programming), but sometimes, a mix of both would be even better.

As always, if you have neat projects you want to show off send me a message! I usually try to keep a balance of languages/domains between the posts, so don’t lose hope if your project isn’t in the latest issue. Just please have a README so you can show others (and me!) how to setup/use your project.

In this monumental episode, Jason and Dan announce both the end of something old and the beginning of something new, and of course cover all the latest Ruby and Rails news.
