the most efficient bioteams use one-way broadcasts and save two-way communications (which take more time) for when they’re really needed.

A bioteam is an organizational structure in which peers share power and responsibility and each member of the team is a both a leader and a follower. The structure is modeled after a fluid leadership structure found in nature.

Some scientists think the leadership rotation also encourages the birds to communicate more effectively.

For those teams that are new to Scrum, I do not recommend eliminating task estimates until you have established a stable velocity.

Once you have a stable velocity, however, you can use the concepts of story points and velocity to eliminate the need for task estimates in sprint planning. The time you used to spend estimating tasks can then be used more wisely to create working software.

Wolfram and his team have built what he calls a “computational knowledge engine” for the Web. OK, so what does that really mean? Basically it means that you can ask it factual questions and it computes answers for you.

It doesn’t simply return documents that (might) contain the answers, like Google does, and it isn’t just a giant database of knowledge, like the Wikipedia. It doesn’t simply parse natural language and then use that to retrieve documents, like Powerset, for example.

Instead, it understands and then computes answers to certain kinds of questions.
