... the better it was.

Create three pages, one of which contains only links to the other two. Now "click" from one of the child pages to the other. On a more serious note - Google may well be a massive generator of links to other sites, but I fail to see its usefulness in being able to click through it to other sites - it does rely on textual input.

FTFY

That's not what the article says, in fact it specifically says

(Note that unlocking is different from "jailbreaking," which opens the phone up for running additional software and remains legal for smartphones.)

so I read it as referring to sim unlocking.

He should have pointed the university admin to RFC2142 then - abuse@[anywhere] shouldn't be available for anybody other than the network admins.

MAC flooding

Well that's just being "clever" for the sake of it. Why can't they just use a simple, keyed, connector - I mean, apart from the obvious?

It could, but that would be wrong.

There's nothing in the standards that says the sending server has to be in the same domain as the mail client.
I can use a gmail server to send mail from a hotmail address, or my ISP's smtp server to send mail from my domain, which may not be big enough to justify it's own infrastructure.

Use OpenPGP, there's the Enigmail plugin for Thunderbird, and a plugin for Outlook. Pretty sure there'll be something for Mac.
Certainly Enigmail can be configured to automatically fetch other peoples public keys.

Actually stabbing someone is very easy. That is why in close quarters, a knife is far more dangerous than a gun.

Do you think so?
Having done neither, I'd always thought that stabbing somebody would be more difficult - having to be "up close and personal", rather than at a distance and somewhat removed from the consequences of the act, as with a shooting.

Doesn't matter, unless they roll out a new CA cert every week.
It's the longevity, and security, of the CA cert that matters.

We've had ferries for years, and there's the channel tunnel as well.

From the Guardian article there's a link to the Princesshay shopping centre which does use this system. Their website has a link to LandSecurities which is apparently the largest commercial property company in the uk. They have a link to a map which shows their retail property locations (http://www.landsecurities.com/retail-portfolio/our-retail-properties-by-location). This is probably a good starting point to determine the shopping centres using this system in the UK.
