For sys admins who want to have a life, here’s your life saver. Rackspace, today, released a new version of its Rackspace Cloud iPhone and iPad app, which lets you run your web empire on the Rackspace Cloud. Here I interview the developer who built it, Mike Mayo.

You can do a whole bunch of things, like start up 10 servers all from one server. Or use Chef to build entire systems all from recipes, or templates. There’s a new passcode lock to keep your kids from messing with your web servers if they find your iPad. Plus it adds AirPlay support, so you can show your mom photos or videos you’ve stored on your Rackspace Cloud servers on her Apple TV. It’s OpenSource too.

Oh, and we’re looking for more kickass mobile developers like Mike Mayo. If you’re one, let us know!

Disclaimer: I’m a full-time employee of Rackspace.

Programmers, you should check this out. Cloud9 IDE has the biggest innovation in IDEs since Microsoft brought us Visual Basic: everything runs on the cloud.

It’s “development as a service.”

What does that mean? Well, instead of coding in text files sitting on your computer, you code directly in the browser window. Here Rik Arends, CTO, and Ruben Daniëls, CEO, show me how it works and explains what it’s good for.

“It’s aimed at developers who want to use the new stuff,” they say.

What do you think? Will you build with it?

One of the things I loaded on my iPhone this week in preparation for SXSW is Bizzy, which is a new location-based app that will help you find businesses near you. Sort of like a cross between Foursquare and Yelp. But they have an interesting idea, called “check out” where you review the restaurant or business as you “check out” of a place. Foursquare lets you “check in,” which tells people and the service itself that you’re there.

Anyway, here the founders of Bizzy Ryan Kuder, VP of Marketing, and Gadi Shamia, CEO, show it to us.
