Should we now rate Google Earth as PG for Brief Nudity ????Ok, so for a little history on computers design. This time about GUI development, and the Demo by Dougals Engelbart on Human Interfaces for computers, back in 1968... this is the first time ever someone uses what later was dubbed as THE MOUSE. Very interesting video to watch. It's over 1hr long, so be patient.
Douglas Englebart completed his degree in electrical engineering in 1948 and settled down in a nice job at the NACA Institute (the forerunner of NASA). However, one day while driving to work he had an epiphany: he realized that his real calling as an engineer was not to work on small projects that might only benefit a few people. Instead, he wanted to work on something that would benefit all of humanity. He recalled Bush's essay and started thinking about ways in which a machine could be built that would augment human intellect. During the war he had worked as a radar operator, so he was able to envision a display system built around cathode ray tubes where the user could build models of information graphically and jump around dynamically to whatever interested them.
Finding someone to fund his wild ideas proved to be a long and difficult task. He received his PhD in 1955, and got a job at the Stanford Research Institute, where he received many patents for miniaturizing computer components. By 1959 he had earned enough recognition to receive funding from the United States Air Force to work on his ideas. In 1962, Douglas published his ideas in a seminal essay entitled "Augmenting Human Intellect." In this paper, Douglas argued that digital computers could provide the quickest method to "increase the capability of a man to approach a complex problem situation, to gain comprehension to suit his particular needs, and to derive solutions to problems." He envisioned the computer not as a replacement for human intellect, but a tool for enhancing it. One of the first hypothetical examples he described for this technology was of an architect designing a building using something similar to modern graphical CAD software.
ESA's Mars Express has obtained images of the Cydonia region, site of the famous 'Face on Mars.' The High Resolution Stereo Camera photos include some of the most spectacular views of the Red Planet ever."These images of the Cydonia region on Mars are truly spectacular, They not only provide a completely fresh and detailed view of an area famous to fans of space myths worldwide, but also provide an impressive close-up over an area of great interest for planetary geologists, and show once more the high capability of the Mars Express camera."
Cydonia is located in the Arabia Terra region on Mars and belongs to the transition zone between the southern highlands and the northern plains of Mars. This transition is characterized by wide, debris-filled valleys and isolated remnant mounds of various shapes and sizes.
Visitors to Costa Rica who insist on driving themselves do so with intuition and pure luck on not getting lock in the face of poor or lack of road signs directing them to their destination or warning of a dangerous curve ahead.
So intense is the drive to deliver high-speed Internet service to American homes that entrepreneurs have seemingly tapped every conceivable pathway: fiber-optic cable, the air, even power lines.
Now the relentless pursuit for faster, cheaper broadband is leading to perhaps the last unclaimed conduit to your house: natural gas pipes.
Nethercomm, a San Diego-area start-up, says it has developed technology to send lightning-fast broadband and TV services via wireless signals through the pipes that deliver the fuel used to heat homes and fire up stoves.
Gas pipes serve 62% of U.S. households, says the American Gas Association. Broadband in Gas, or BIG, could give consumers a third high-speed option at low costs and speeds that far surpass today's phone and cable offerings. It also could bring fast Internet to unserved rural areas. But, so far, the idea has been met with both excitement and skepticism.
"It's been a Coke and Pepsi (battle) between cable and phone companies," says
Nethercomm founder and CEO Patrick Nunally, 42, a veteran high-tech
entrepreneur. "We're in a position to come in and provide real competition."
More important, Nunally says, the pipes could be used by pay-TV providers to compete with cable and satellite. In fact, he says, Nethercomm and local gas companies would lease the wireless spectrum to any provider for myriad services: cable giants seeking extra bandwidth for their high-definition TV channels, phone companies looking to pare their multibillion-dollar investments in fiber-optic cable, even businesses such as medical providers with high-bandwidth needs.
Gas companies, besides earning revenue from leasing their pipes, could use the broadband service to remotely monitor the integrity of their lines and read gas meters.
"I think there is a general pulse of excitement" about the technology among publicly owned gas companies, says Bob Beauregard of the American Public Gas Association, which represents 650 gas providers serving 5 million rural customers.
Nunally says he hatched the idea in 2002 while searching for a new TV and broadband artery to the home that didn't require digging up streets. Around the same time, some California utilities were stringing fiber cable through gas lines to offer broadband. But the process was expensive.
Nunally says he had a "light bulb on the head" moment: wireless. Normally, the twists and turns of a gas pipe would cause wireless signals to lose strength. But ultrawideband, a new unlicensed wireless technology, sends out pulses of radio energy across such a wide swath of frequencies that if some data packets are lost, others can easily make it to the home.
Also, federal rules that limit the strength of ultrawideband signals don't apply in underground pipes. So, Nunally says, power levels can be boosted to provide each household bandwidth of up to 6 gigabits per second, several times that of a cable provider. Yet power is low enough so that signals can share the pipes with natural gas without starting a fire, he says.
A similar initiative, broadband over electric lines, is further along, with services offered in Manassas, Va., and Cincinnati and a rollout planned for Dallas this year. But the electric companies don't offer TV services and incur high costs to bend signals around transformers.
Broadband in Gas would require installation of an ultrawideband transmitter that's linked to an Internet backbone or pay-TV facility at a gas company's network hub. A receiver would be placed at a customer's gas meter. Build-out costs are about $200 per household, Nethercomm says. By contrast, broadband over power lines costs about $600 per household, while phone and cable TV networks each cost well over $1,000 per home to build, says West Technology Research Solutions.
Broadband in Gas "really has the potential to accelerate adoption of these technologies," says George West of West Technology.
Yet some say BIG is, well, a pipe dream. "It's really easy to make these kinds of claims, but it's much harder to prove in practice," says JupiterResearch analyst Joe Laszlo.
Nunally says the company, which has tested the service, plans field trials next year in San Diego, Chicago and Atlanta. But officials of Nicor Gas in Chicago and Atlanta Gas Light say they have no such plans.
"We're intrigued by the technology, but we never got that far in our
discussions,"
says Nicor spokeswoman Margi Schiemann.
Nunally says BIG could sharply cut costs for companies such as Verizon Communications, which is spending $20 billion on fiber rollouts. Verizon and Internet provider EarthLink say they have no immediate plans to deploy it.
And Freescale Semiconductor, the ultrawideband company that was working with Nethercomm, recently shifted course to focus on its handset business. "It would be hard for anybody to say (BIG) doesn't have tremendous potential," says Freescale's Jon Adams.
THE Crocodile Man, Steve Irwin, is dead. He was killed in a freak accident in Cairns, police sources said. It appeared that he was killed by a sting-ray barb that went through his chest, Queensland Police Inspector Russell Rhodes said.
He was swimming off the Low Isles at Port Douglas where he had been filming an underwater documentary when it occurred.
Ambulance officers confirmed they attended a reef fatality this morning at Batt Reef off Port Douglas.
Mr Irwin, 44, was killed just after 11am, Eastern Australian time.
His American wife Terri learned for the tragedy from police in Tasmania, where she had been trekking in Cradle Mountain National Park.
His friend and manager John Stainton said Mr Irwin was filming some segment for daughter Bindi's show on the reef between sessions filiming the main documentary.
It is understood Mr Irwin was killed instantly.
A source said Mr Irwin was already dead when his body was brought onto the Isle.
A source said Mr Irwin's body was being airlifted to Cairns Hospital in North Queensland for formal identification.
An Emergency Services Response Management spokeswoman said they received a call about the tragedy at 11.11 am, Australian Eastern Standard Time.
