Exactly.

The student OWN their laptop. Period.

You should not (legally) have (the right) to lock down their laptop.

I think the main problem is how you view the design of the network they will connect these laptops to.

I think you must consider these laptops connecting to the physical school network as equivalent, security-wise, as if they came from the outside (the internet). You are simply providing wired local access. The school systems and services should exist on a seperate secured network.

And just like in an airport or an internet cafe, you probably can filter some of the traffic to-from the 'public' physical school network.

Is monitoring the traffic to-from a privately owned laptop legal in the U.S.?

## Submission + - The Six Dimensional Space-Time Theory

eldavojohn writes: "PhysOrg is covering an interesting year old paper that proposes an alternative space-time relationship theory. His resulting proposition, based on Einstein's general relativity and Elie Cartan's triality concept, is a Twister Space (which I've only read of in Roger Penrose's latest work). The basic gist of his theory is that space-time is not modeled by four dimensions but instead six. He's hoping that tests from the Large Hadron Collider will help prove his theory. The extra two dimensions are time like or related to time and are the designated twisters in his equations. He's coining this as a "Xi transform" and cites the rationale of these extra dimensions to be providing symmetry — the product of a wave operator and a Xi transform, taken in any order, is zero. The three dimensional space model is s2 = x2 + y2 + z2. The traditional four dimensional space-time model has a critical minus sign, s2 = x2 + y2 + z2 — t2. Sparling is proposing a model that resembles s2 = x2 + y2 + z2 — t2 — u2 — v2, where u and v represent the new time variables. The implied connotations the new theory holds are massive would rock the very concepts of future versus the past, the paper is heavy but the PhysOrg article summarizes it nicely."

## Submission + - One Terabyte! How am I going to store that much!

On March 16, 2007, UPS delivered to our storage test lab a shipment from Hitachi, which we had anticipated for several weeks. The box contained the world's first hard drive with a total capacity of 1 terabyte (1 TB): the Deskstar 7K1000."
