Snappy headlines: amusing and educationally sound
This is funny if you know a few basics about quantum physics, simply because of the instant joke that stems from it: Quantum Cryptography Broken, and Fixed.
The joke is in the comments to the article - "It was actually broken AND fixed at the SAME TIME!"
It's an easy one - an earlier series of comments is even better:
> Quantum stuff is so illogical to us mortals that you'd expect attempting to break it would just make it stronger.
Which is precisely what happened.
It continues along these lines, becoming progressively more incomprehensible to people who aren't interested in this sort of thing.
Which of course is a sign that I should probably get back to studying for my exam.
Ironically, however, reading articles like these at /. (slogan: New for nerds, stuff that matters) is technically a form of studying if you focus on security issues and ignore the non-essential nerd stuff, like HP's deal to buy EDS which is important for many reasons - perhaps you own shares or work there - but it won't help you much on this exam.
There's an even greater irony, though, in the fact that I couldn't write a snappy headline in an article about snappy headlines. At least the Parisian hallway in the above looks sort of cool.
