The Penn Bain Way
If Mitt ran USA like Bain, he'd run up debt, charge USA huge "management fees", let it go bankrupt, sell it to China and Saudi Arabia, kick us out of our houses, and then sell our houses to the highest international bidders.

WSJ Internet Invention Spin-Job
On the July 23rd, 2012 print edition of
the Wall Street Journal, page A11, L. Gordon Crovitz claims that the
Internet is mostly the result of private research and investment,
countering Obama's statement about its government roots. Typical of
Murdoch products, it's full of half-truths, textual manipulation, and
borders on outright lies.
The Internet is a combination of
technologies developed over time, and private firms did indeed have a
role in its evolution. But the majority of the Internet technology
development was directly or indirectly related to government funding
from the US and other governments around the world.
The most glaring fault of the article
surrounds ARPANET, a military project. Crovitz quotes Robert Taylor,
who was part of the ARPANET program of the 70's and 80's. "ARPANET
was not an Internet. An Internet is a connection between two or more
computers", Taylor allegedly stated. While technically true
perhaps, it misses the point of ARPANET's role in history. ARPANET
pioneered the use of "packet switching" to send data
packets in partitioned chunks with routing and ID info in order to be
"reassembled" on the receiving end.
This differed from the old way of
having direct lines of communication for the bits. Chunk-ifying the
data gives more flexibility to work around high-traffic and defective
spots on a network. It's almost comparable to using trucks versus
trains. While trains are good at high-volume transport between a few
fixed points, they are not flexible if you have many different
destinations. (Data terminals, which are a kind of remote computer
monitor, were one early use of ARPANET.)
Whether or not this "is" the
Internet is secondary to the fact that the Internet is heavily based
on packet switching. Murdoch's, I mean Crovitz's complaint is almost
like saying early rockets didn't matter in the history of rockets
because they "never reached space". His reason for
dismissing it is very weak. Packet switching is arguably the most
important part of the Internet technologies. Ethernet (below) had
decent alternatives, but packet switching was new and unique. It's
not the standard that stands out, it's the technique itself.
The article correctly points out that
Ethernet, another part of Internet technology, was developed at
Xerox, the private copier corporation. However, it was inspired by
ALOHAnet, which came from the public University of Hawaii. (It seems
building time-travel devices to forge Hawaiian birth certificates takes
cutting-edge technologies.)
Crovitz's other Xerox references
relating to graphical interfaces and early PC's are mostly tangential
to the Internet, but still misleading regardless. For example, he
failed to credit university research on Ivan Sutherland's "light
pen" based graphical user interface work, and Douglas
Engelbart's invention of the mouse at Stanford. Stanford was also
instrumental in testing and developing hypertext.
Much of early graphical interface
research was motivated by military command and control centers, which
wanted faster ways to visualize and select ("point to")
various radar targets on the screen. The Air Force SAGE system is an
early example.
Many of the World Wide Web protocols
and language techniques were developed as part of CERN, The European
Organization for Nuclear Research, a government organization.
Here is a copy of the very first
web-page:
The Internet and the World Wide Web are
technically two different things, actually; but in practice most
consider them closely related. Further, the Australian government
under CSIRO developed some key parts of WiFi technology that we
commonly use in our homes to allow multiple devices to connect to the
internet.
Eventually the Internet was
commercialized as Crovitz points out, but that's irrelevant to
Obama's comments about its origin. If big business had it its way,
the we'd still be using the slow, proprietary, and expensive network
services such as Prodigy, CompuServe, and America Online that popped
onto the scene around the early 1990's. They were much more
profitable than the Internet because corporations controlled
distribution and content and were happy to milk customers.
However, college kids playing around
with the early Internet and Web services sponsored by universities
realized the potential of a more open alternative capable of sharing
info across different computer brands and networks.
