First things first, sign up for Bluemix! What is Bluemix, you ask? It's IBM's simple and flexible cloud development platform. Whether you're looking to build a web app or a mobile backend in the cloud, Bluemix has you covered with a variety of runtimes (like Node.js, Python, Ruby on Rails, Java, etc...) and services (like Mobile Push, Cloudant, Twilio, MongoLab, etc...) that we're sure will fit your app's use case.
Since this is a relatively short event, a Bluemix 30-day free trial is well suited to anything you're looking to build for now - no up front credit card required either! Once everything is said and done (and you've won, right), you'll have an awesome app running on Bluemix and all the enterprise-grade tools at your disposal to take it to the next level.
Check out our Dev 2 Dev forum any time you need a bit of extra help. If you ask a question in the forum, tag your post with MixHack so we can track your questions and respond even faster!
Oh, and you can tweet us too (if that's more your style)!

Most importantly, don't forget to submit your app to us at the end of a Bluemix hackathon! Doing this will enable you to win awesome prizes from us (including free Bluemix - to get your app to the next level afterwards). Be sure to ask IBMers at your event about specific prizes. Use the link below to submit that app now!
Hint: to make it count, you'll need a submission code issued by IBMers at your hackathon. One submission per team please.
