Pranav writes "Using semiconductor lasers, scientists from Takushoku University, Saitama University, and NTT Corporation achieved random number rates of up to 1.7 gigabits per second, which is about 10 times higher than the second-best rate, produced using a physical phenomenon. Future work may center on devising laser schemes that can achieving rates as high as 10 Gbps."

The "Real Genius" and "sharks" jokes you're about to post are less than 1% as funny and clever as you think they are. And no, you're not making them ironically, you're making them because you really do think they're good jokes. This is because you are retarded.

They should somehow tap into phpBB. I'm already on some forums that generate more than twice this much bullshit every second :)

Austin Powers came out over 10 years ago. At some point (and that point was years ago), making references to it every time you see either the word shark or the word laser becomes old. It's really not funny.
Shhh!
Just know that I've got a whole bag of shhh! with your name on it.

I suspect encountering the words "random" and "laser" in the same sentence would be rather disconcerting to an eye surgeon. Maybe I'm off topic...

Just SHA /. articles and comments. Should be no chance of being random.

Agreed. Someone once told me about one of John Ellis [wikipedia.org]'s students asking them to do a Monte Carlo simulation, and sending the results back saying "it's not random enough". Ignorance about random number generators is everywhere.

No, not at all. Diebold voting machines are specifically designed to eliminate sources of randomness in order to deliver predictable results.

You must be new here. We get very few "Real Genius" jokes around these parts, and many go unrecognized. Quite sad, I'm afraid... ...or in deference to you Kent, it's like lasing a stick of dynamite. :-P

Once again, the subtle humor gets looked over but the bleeding obvious get +5... Glad to have set you up :)
