I just found this site, I have assigned some quizes that you can try out use this access key 153405-sQxx
I will wipe this class set just before the exam. Feel free to use a fake name, although the site does look quite good and I will be spending some time over the summer checking it out.

Microsoft Mirage Table
The kinect is basically a depth sensitive web cam. Researchers at Microsoft have created a 3D video conferencing tool that includes aspects of augmented reality as well as 3D scanning.

More details here. Now the thing is that this looks a lot like a scene from Minority Report (the 2002 movie). However, while the film has 3D holographic projectors, running from a 2D source. Microsoft has 3D capture and uses a 3D projector to convince the user that they are seeing in 3D.

A question from a Pupil
Hi, I’m currently studying computing on Scholar and one of the answers to a question I disagree with. The question is “a program stores the user IDs of 20 SCHOLAR users. Which of the following would be the most efficient way of storing this information?” and the possible answers are:
- 20 integer variables
- an array of integers
- an array of strings
- 20 string variables
Scholar says the answer is an array of strings, but why? I thought the answer would be an array of integers, as to log into Scholar you just use numbers. Please explain why it is an array of strings ?
