Comment Using the potty. (Score -1, Troll) 151


After he went poo-poo in the potty, how did he ensure his bummy-bum was clean if he was unable so see the toilet paper? Did he use a bidet in the dark? Were the ravioli poo-poos gross and, what we call, "two-flushers" in our house? How would he know when the potty has enough toilet paper in it?

Seriously, if you're going to do science, you have to include the poo!

I looked at Google last night and fell off my chair when I saw a differnet, yet oddly familiar, logo. Many dozens of other news outfits were reporting on it, but I waited until I saw the story on Slashdot to confirm it.

Slashdot is to logo confirmation as Netcraft is to BSD's death confirmation.

Comment Good job Wikipedia! (Score 5, Funny) 142


I was sitting here drinking a refreshing Coca Cola when I started reading this story on my Apple iPhone 6 Plus. The level of paid shills that infested Wikipedia were getting bothersome. It was at the point that I started using my Encyclopædia Britannica (2015 edition).

Sorry if I don't get to your replies sooner, I'm taking the Prius to Chipotle for a GMO-free lunch.

There are airborne optical alternatives that can beat the * out of fiber - provided the weather is clear.

Fibre provides more frequency and better SNR than you'll get in the air, thus more bits

But a single fiber provides ONE PATH. Optics can provide MANY paths.

Imagine ten thousand fibers. Now imagine the ends poking out of a billboard in a 100x100 array - behind a 100x100 array of collimating lenses that beams the light toward your house. At your house imagine a telescope imaging that billboard onto a slide containing another 100x100 array of fiber ends. (Of course the fibers work both ways0 The air path may be of lower quality than physical fibers, but it's hard to beat a four orders of magnitude more paths. You'd need to run an actual bundle of hundreds or thousands of fibers from the billboard site to your house to beat it.
:
Now go back to the billboard and insert another 100x100 array of fibers through it - slightly offset so the same set of lenses but beams toward your next-door neighbor's house. (We'll assume the array is spaced out sufficiently that an optical telescope can resolve the two houses.) Repeat for ALL the houses served.

Not practical as described, of course. But it shows the principle: Wireless paths can multiplex spatially and reuse the bandwidth a hysterical number of times.

(Of course a real system using spatial multiplexing could be expected to use various wave-mechanical hacks rather than actual resolved paths - just as MIMO does down at radio frequencies.)

As long as we're going to reinvent the wheel again, we might as well try making it round this time. - Mike Dennison
