Actually, any electromagnetic radiation has the potential to be ionising, depending on the material it hits.
This is due to the photoelectric effect which, simply put, means that if an incoming photon has an energy higher than a specific value, (called the material's work function), it will give an electron in that material enough energy to break free and disappear off elsewhere. The material then gains a small positive charge - in other words, it becomes ionised.
Of course EM radiation in the sort of bands that WiFi uses has nowhere near enough energy to do that to most materials. So yes, it's nothing to worry about and yes, I guess I'm just being pedantic. Oh well:)
Rotating relative to an inertial reference frame. The halter isn't one of these, because any point on it is continually accelerating (ie. changing speed and/or direction of motion). I realise this now I've had time to think about it properly.
BTW: What exactly do you mean by "halter"? I Wiki'd it and all I could find was something worn either by women or horses (depending on the sort of halter you're talking about).
OK, I may be making a fool of myself here, but how can the entire Universe's angular momentum be non-zero? Surely momentum can only ever be relative to your frame of reference - and by definition, any frame of reference you can think of will be within the system you're trying to measure.
Although... thinking as I type here... say you were sitting on a massive spinning top, and all you could see was the spinning top. You'd still feel centrifugal force, as a result of its spinning. Could be an interesting explanation for dark energy?
(and yes, now I remember that important word "inertial" from A-level Physics lessons. Meh...)
There is already a technology of printing ICs on paper
Would you mind providing a link to that? I've not heard about this before, and it sounds fascinating... I guess I probably just saw it, thought "more wearable computer nonsense", and ignored it:)

Why not just have the machine shut down automatically on logout if it's between two specified times (eg. 9pm and 8am)?
I thought Greenpeace had some beef (tofu?) with Macs anyway. Probably to do with carbon footprints or recycling or something.
Perhaps this disk is the environmental lobby's means of wreaking revenge on those nasty, conservative, planet-hating Mac users...
Yes, as long as Office doesn't hang first.
Useful when you're fighting off the folks from Western Digital when they come round to build DRM into it.

My friend, you are misinformed! Thanks to SVG support, you can make GNOME's footprint as big or small as you like, with no loss of quality whatsoever!
Does that make you infinitely geeky if you don't actually have Windows in the first place?
Neither are migratory. The point is moot.
GP's name is Richard. He's just signing off his post.
Ah, I see what you mean.
Unfortunately I can't receive Freeview where I am, (no roof aerial; rented house). Bugger.
Could you please provide a link to all these free MPEGs?
I wasn't previously aware of their existence.
That's no moon...
It's the solar system's biggest porn collection.
And also the sort of people who operate Tor servers have a tendency towards obesity...
The FSM isn't going to be happy about this...
Joking aside, what exactly is NTP if not Network Time Protocol?
That acronym means nothing else to me, but the summary simply assumes that everyone already knows who they are.

No, I imagine I'd be pulled off the cliff whether I liked it or not by the massive gravitational field...
+1 Paranoid...
*whoosh*
Couldn't that problem be at least mitigated by OS-level write caching?
I didn't modify that eye! It must just be the headset changing the shape...
Argh, godammit - not only has it already been done but it's far better than mine (below). Curses!
Like this, you mean?
(Lucifer's beard it took too long to make that - I'm getting rusty)
