Key based authentication for SSH is a way to connect remotely to another computer/server using an encrypted file you HAVE and an optional password you KNOW to unlock the file. Key based authentication has the advantage of being more secure and/or more convenient.

Ever wonder how to level sound volume on a recording or podcast? The Levelator is a super simple application for Mac or Windows to level out sound volumes on a podcast recording. Mike Farmer and I use it for our podcast over at http://technologyforlearning.info and it works wonders for the times when we accidentally move away from the microphone. It’s free and it works great so what are you waiting for? Go download it from their site at http://www.conversationsnetwork.org/levelator
I am totally geeking out about this! Found the link through a fried on Twitter and I think it illustrates the power of giving young children the tools to each learn at their own pace. They also are a bit more motivated and excited about being able to use such a cool piece of technology.
