And then Windows 8. If you learn how to build apps for Windows 8 you’ll emerge with skills that are bang up-to-date and are readily transferable into your day job. But again, you might make some small amount of money shifting applications. But things get more interesting after next Christmas…

John Heller was on assignment for Getty Images at the Egyptian Theater in Hollywood, when his Nikon D3 and lenses were stolen, but it wasn’t until a substantial amount of time later that he searched for the camera’s serial number on GadgetTrak’s service, which has indexed all the serials embedded on images from 500px and Flickr from 2006 onwards. With a positive hit on a couple of photos on Flickr, the police were able to track the camera down to a photographer, who bought it not knowing its origins — and even had a receipt for the transaction.

That is the big difference between Google Plus and most other networks. Twitter is an all or nothing model. You can share with everyone or you can only share with all the people that follow you. But you can’t share with only a sub set of the people that follow you (such as a specific Twitter List.) Facebook is a little more flexible than that. But you must be friends with people or you must reduce your privacy. You can limit who sees individual things you share, but it is difficult to do and not intuitive to get set up.

It seems that Google learned something from its former employee Paul Adams. His presentation of the real life social network illustrates the problem of using facebook and shows how personal networks are more complicated than the facebook philosophy of everything about you should be public. Look at the whole presentation to see understand his point.

The app takes a picture of a mole on the skin, then uses a proprietary algorithm to look at the fractal-like shapes which exist in human skin (have a look up close, you can see little triangles in normal skin, honest). It then calculates if the shape of the mole means it is is developing normally, or abnormally thus in a into a potential cancerous melanoma.

If we want to take back control of our workday schedules and priorities, the only way to do it is by relentlessly questioning how we’re spending our time. But what questions should we ask?

I reached out to a handful of regular 99% contributors and 99% Conference speakers to get their insights on daily energy and task management. Here’s what they said:

I understand why the top students in America study physics, chemistry, calculus and classic literature. The kids in this brainy group are the future professors, scientists, thinkers and engineers who will propel civilization forward. But why do we make B students sit through these same classes? That’s like trying to train your cat to do your taxes—a waste of time and money. Wouldn’t it make more sense to teach B students something useful, like entrepreneurship?
