"Ever needed to know the age of a Web page only to discover that it lacks a time stamp saying when it was published? If so, then the work of Hany SalahEldeen and Michael Nelson at Old Dominion University in Norfolk, Virginia, may be of interest. These guys have created a Web application called Carbon Date that works out the creation date of a page by searching for the earliest evidence of its existence."

We believe that everyone is creative, inventive, and imaginative. We believe that everyone can create the future and change the world. So we have dedicated our lives to making easy-to-use invention kits. Before we created MaKey MaKey we worked on other creative tools and invention kits such as Drawdio, Singing Fingers, and Scratch.

Unhangout is an open source platform for running large scale online un-conferences. We use Google Hangouts to create as many small sessions as needed, and help users find others with shared interests. Think of it as a classroom with an infinite number of breakout sessions. Each event has a landing page, which we call the lobby. When participants arrive, they can see who else is there and chat with each other. The hosts can do a video welcome and introduction that gets streamed into the lobby. Participants then break out into smaller sessions (up to 10 people per session) for in-depth conversations, peer-to-peer learning, and collaboration on projects. UnHangouts are community-based learning instead of top-down information transfer.

"One Laptop Per Child project founder Nicholas Negroponte said that the organization is accelerating its development of the XO-3 tablet computer and will have a working prototype by December 2010, two years ahead of projections. Negroponte said the final product would cost US$75."

The XO-3 OLPC laptop will be released two years ahead of schedule and cost about $75 US. Amazing to see all this techology come together. Tony and I are working with what we can do with the Sugar interface in the classroom.

New website for sharing resources around Scratch multimedia programming.

"Vanished" is a two-month-long game, which debuted the week of April 4 and stems from an initial scenario revealed in recent video messages on the site. The premise is that people living in the future have contacted us in the present, to answer a question: What event occurred between our time and theirs that led to the loss of civilization's historical records? Students must decode clues in hidden messages, and in response find and provide information about Earth's current condition, such as temperature and species data, to help people in the future deduce what wound up happening.
