Do you have any figures about this? Mobile air conditioners with COP of 2 or so are being developed these days (IPCC/TEAP special report, page 306), and I can't imagine the energy consumption is significant compared to the actual transport, unless the temperature differences are extreme. I'm willing to be proven wrong, though.
There's some information about visiting students in Cambridge.
Very few students are accepted, especially in technical subjects, and they normally study the first or second year (so compsci part IA or IB, not II). Cambridge also has an established exchange program with MIT, where applications are somewhat less competitive for those coming to Cambridge.
a clever sysadmin would post rewards to any student who could game his system and show his work, so the sysadmin could plug the identified security holes.
Just remember to avoid ad hockery.
When a new network admin came to our school, they asked idle computing students to find and report ways to get past the system restrictions.
Initially we thought it was cool, but when we reported that access rights to network drives can be changed by right clicking the drive under My Computer, the admin completely disabled right clicks on all computers.
When we reported that by pressing Win+R and typing "cmd" we had access to local drives (that you couldn't access using explorer), rather than fixing the access rights, the admin disabled the "Run" dialog. We all had access to VB (ugh) and could get to the command line through there, of course.
If you don't get the restrictions right the first time, correcting each hole as it is discovered will only advance towards an unusable system. Use the tips from students not as a TODO list, but as an indication that something is wrong in your initial assumptions.
When they say 4D they actually mean 4 spatial (geometrical) dimensions.
Although time is said to be the 4th dimension is time, it is only an analogy. Time appears in several physical equations in a context similar to the 3 spatial dimensions, but it is always treated differently.
For example, the spacetime "distance" is calculated by:
sqrt(x^2+y^2+z^2-c^2*t^2)
Notice the negative sign and the additional speed-of-light factor.
If there were 4 spatial dimensions, the distance would be calculated by
sqrt(x^2+y^2+z^2 + v^2)
taking v as the displacement in the 4th dimension.
The Rubik's cube programs work by projecting 4 or 5 dimensions onto a 2 dimensional plane (your screen), basically in the same way that perspective is used to project 3D pictures onto 2D planes.
So the 4th and 5th dimension aren't mathematically or conceptually different to the familiar 3 dimensions. The only difference is that we cannot comprehend them.
The streets in Britain are flooded with CCTV. This new development just adds to the infrastructure for the next totalitarian goverment. Although I trust the current goverment to use technology for good, sooner or later this technology will be abused against Britain's own citizens, by a less democratic government.

I don't know how this is relevant to the discussion, but you may want a blank screensaver to automatically lock your computer when you're away.
Sorry if I missed some sarcasm there.
Well, I don't know what problem spiffmastercow had, but this bug has been around since the launch of 11.04, and crashes my laptop on a regular basis.
The cap mentioned in the article is 250Gbit, not 250GB. 31GB is about 20 hours of HD video.
Isn't that how RMS browses the web?
Clearly, the x-axis is the amount of knowledge accumulated and the y-axis is the total time spent so far.

Programming to lion taming in one go...
You don't think it might be better if you worked your way towards lion taming, say via software engineering?

And people here are worried about ID cards.
