"I'm also curious about Google and the like. Do they not disclose their storage?"
To a certain extend they have disclosed some numbers in a paper about their distributed storage system called "BigTable". The title of the paper is "Bigtable: A Distributed Storage System for Structured Data" and it can be found right here.
Some numbers can be found on page 11:

It's a very interesting paper to read. One of the many papers Google has put online:
No, girlfriend waveforms can collapse in such a way that one can actually have one. This may not happen often when combined with the/. waveform.. but every now and then it does happen.;)
I'm amazed that none of you have ever heard of the Girlfriend Money experiment: when a girlfriend (especially your own) looks at a certain amount of money, she'll cause the collapse of the money's superposition. This _always_ results in the money disappearing both completely and instantaneously.;o
Would it not be somewhat of an improvement then if services like these would also be massively distributed? Instead of a massive scammer network having a 'force to counter' in the form of a massive anti-scammer network. Surely a p2p/torrent like thing could make this possible?
I'm not a specialist when it comes to transmitters and receivers, but I found a few more bits of information that you might find interesting:
"After launch, Pioneer 10 was capable of transmitting data at a maximum data rate of 2408 bits per second. Now the data rate is 16 bits per second. Reducing the bit rate compensates for the reduced signal strength; it is like speaking more slowly to enunciate more clearly. The signal strength from the craft's main transmitter is now about 7.8 watts; by the time it reaches the DSN antennas, the signal has diminished to less than a billionth of a trillionth (10-21) of a watt."
"Successfully sending a DSN signal into Voyager-2's receiver is like throwing a baseball across thousands of miles of ocean into a porthole of a moving cruise ship."
I once read that the strength of this incredibly weak signal was not the problem. After doing a search, I discovered that it is indeed the decaying (pun intended) power supply and not the communication signal that will become the problem when it comes to communicating with those probes in decades/centuries to come:
"* Barring any serious spacecraft subsystem failures, the Voyagers may survive until the early twenty-first century (~ 2020), when diminishing power and hydrazine levels will prevent further operation. Were it not for these dwindling consumables and the possibility of losing lock on the faint Sun, our tracking antennas could continue to "talk" with the Voyagers for another century or two!"
Just to be clear: I did not intend to say that technology from the 70's was not good enough. I meant it more as a compliment to the men and women who designed this whole thing. For example: perhaps they were still using slide rulers at times[1]. This compared to the 'fancy CAD/CAM systems' that are now available on each desktop computers because those are now powerful enough to run such software now.
Perhaps not the best example, but it's all I can think of right now to (hopefully) help make my underlying intention clear.
[1] "The use of slide rules continued to grow through the 1950s and 1960s even as digital computing devices were being gradually introduced; but in the early to mid 1970s the electronic scientific calculator made it largely obsolete and most suppliers exited the business." http://en.wikipedia.org/wiki/Slide_rule
It's not millions of miles per gallons. Launching costs quite a bit of fuel:
"Voyager's fuel efficiency (in terms of mpg) is quite impressive. Even though most of the launch vehicle's 700 ton weight is due to rocket fuel, Voyager 2's great travel distance of 7.1 billion km (4.4 billion mi) from launch to Neptune results in a fuel economy of about 13,000 km per liter (30,000 mi per gallon). As Voyager 2 streaks by Neptune and coasts out of the solar system, this economy will get better and better!"

Oh Hai! I collapsed ur wavefunction! :p

After 'Snakes on a plane', will we now get a sequel called 'Bacteria on a Space ship?'

If positrons are not hard to find, why am I still not seeing any androids with positronic brains walking around all over the place? :P

I'd say there's nothing wrong with Python += 1

For torrents I have become quite a fan of rtorrent [ http://libtorrent.rakshasa.no/ ]
It's both fast and very light-weight!
Welcome to Spice World! We'll now continue start an eternal loop of the song 'Viva Forever'. Enjoy your stay. :P
Too much girl power will kill you. ;o
The spice expands consciousness~ ^_^
Perhaps Homer isn't even saying always "Do'h!", but "tau!" :p
Well, in The Netherlands, the police can fine you for leaving your bike unsecured. (At least so I have been told my an acquaintance)
(that should obviously be 'something'. lack of sleep and volatile memory.. see it's effect right now! =/ )
"volatile memory" is a fitting name for somewhat that changes depending if you look at it or not, that's for sure! ;P

I just cannot praise the people who made and make this project possible enough. The facts are jaw dropping!

(Still a great distance to travel, but should that not be 14 hours instead of 14 days?)
