Wireless Network being tested at Ground Zero

What a great use of wireless technology. Hopefully many lives will be saved with this.

Fire, technology and Port Authority officials tested a new wireless system designed to give first responders fast access to video and other data during a fire drill on Sunday at the World Trade Center site.

Last year, city officials announced they had selected the Los Angeles-based Northrop Grumman Corp. to build and maintain the multimillion-dollar citywide high-speed wireless data network for police, fire and other city workers.

Some 100 firefighters participated in Sunday’s simulated fire at 7 World Trade Center, which stands in the shadows of ground zero in downtown Manhattan. The exercise included 20 mock injuries and a rescue from an elevator shaft, said Joseph Pfeifer, chief of counterterrorism at the Fire Department of New York.

Officials tested sending surveillance video from the building’s 50th floor to the network operations center and from there to the fire department’s operations center in Brooklyn, allowing them to monitor the scene remotely, Pfeifer said.

Wes Freyer gets it right

There has been a lot of news lately about students using iPods and other electronic devices for cheating. Wes has addressed the issue better than I could ever hope to.

Rather than adopting policies about technologies that are banned, school districts would be better advised to have their teachers craft new assessments. Our goal should not be, “How can we maintain our instructional and assessment paradigms from the 19th century today in our 21st century digital culture?” but rather “How can we craft authentic assessments our students cannot fake and they can take with open notes?” Open notes should include “open devices” like cell phones and iPods.

The problem with this proposal is that it is very challenging to write and use authentic assessments. It is much easier to test at the knowledge and comprehension level, and that is why we see so many teachers doing it. When you want to have statistical reliability and validity with an assessment, it becomes much more difficult to assess higher order thinking skills with “messy assessments” that include rubrics and subjective analysis. NCLB also encourages this simplified look at assessment, encouraging school districts, administrators and teachers around the United States to focus almost exclusively on multiple-choice, black and white forms of assessment that can be graded via a scantron.

Stephen Hawking Weightless

Very cool! I’m glad he got to fulfill a dream.

Whirling like a “gold-medal gymnast”—as one crew member put it—Stephen Hawking took blissful leave of his wheelchair for a 90-minute airplane flight featuring 25-second bouts of weightlessness.

“It was amazing,” the British astrophysicist said in a statement. “I could have gone on and on—space, here I come!”

Operated by the Zero Gravity Corporation, the flight followed a rollercoaster-like route, creating weightless conditions at the crest of each arc—a method used to prepare astronauts for space travel. A padded cabin, heart-rate and blood-pressure monitors, four physicians, and a nurse helped keep the A Brief History of Time author from harm.

ALS, or Lou Gehrig’s disease, has rendered Hawking paralyzed and mute. Using eye motions and a synthesizer to communicate, he had said before the flight that “it will be bliss to be weightless,” according to the Associated Press.

Hubble Telescope turns 17

I’m going to miss it, but NASA will keep up the good work long after it is gone.

The wonders of astronomy meet the drama of modern art in this latest image from the Hubble Space Telescope.

The color-enhanced image, taken of the distant Carina Nebula, depicts the birth pangs of a dozen stars, as explosions send waves of superheated gases billowing through the southern constellation Carina.

The raucous stellar nursery makes a particularly fitting subject—scientists released the image today in honor of Hubble’s anniversary, marking 17 years since the orbiting telescope was borne into space on the shuttle Discovery.

This painterly picture brings the total number of images that Hubble has taken since 1990 to nearly 500,000.

To date, the telescope has made nearly 800,000 observations of more than 25,000 celestial objects and has traveled 2.4 billion miles (3.8 billion kilometers)—the equivalent of flying to Saturn and back.

But scientists are also casting an eye toward Hubble’s inevitable end.

NASA officials finalized plans today for the telescope’s last round of repairs, scheduled for September 2008. Shuttle astronauts are expected to install two new instruments and provide enough new materials to keep Hubble operating through 2013, when Hubble’s successor, the James Webb Space Telescope, is slated to launch.

Sharing your home broadband connection

What a great concept!

Spanish network provider FON and Time Warner Cable announced a new partnership on Monday that will allow that latter company’s broadband subscribers to also access the FON Wi-Fi network for free.

Under the new agreement, Time Warner cable subscribers can also become FON community members and create their own access points through their home or business broadband connections.

These community members, which the company calls “Foneros,” essentially serve as Hotspot providers who then share their unused bandwidth via a specialized FON router in exchange for free Wi-Fi access when roaming through any other FON access point, the company said.

Subscribers will use FON’s “La Fonera” router, which offers two distinct Wi-Fi channels, according to the company. One channel is dedicated for the exclusive use of its owner while the other channel is shared with those other “Foneros.”

For those concerned about privacy and network piggybacking, FON claims that the router actually increases security through an encrypted private network, and that Foneros can decide on how much bandwidth to share. What’s more, public users will not be able to access the private network as there is no anonymous usage.

With nearly 60,000 community members so far in the U.S., FON claims that it is now the largest Wi-Fi network in the United States. Through the new FON/Time Warner partnership, cable subscribers can also have free unlimited Wi-Fi access at any of FON’s partner ISP Wi-Fi hotspots in the U.S. or abroad, according to the company.

2,074 Editors

If you had any doubts as to the importance of Wikipedia, this should calm them. I’m not saying it is a perfect system, but it’s pretty darn good. In the academic arena, it is good practice to think of Wikipedia as a good place for search, while not always a good place for research. Consider the difference between the two as you look at the following article.

Imagine a newspaper with more than 2,000 writers, researchers and copy editors, yet no supervisors or managers to speak of. No deadlines; no meetings to plan coverage; no decisions handed down through a chain of command; no getting up on a desk to lead a toast after a job well done.

It doesn’t sound like any news operation that any journalist would recognize. Yet that seemingly chaotic nonstructure best describes the scene at Wikipedia, the online encyclopedia, which, for a few days last week, served as an essential news source for hundreds of thousands of people on the Internet trying to understand the shootings at Virginia Tech University.

From the contributions of 2,074 editors, at last count, the site created a polished, detailed article on the massacre, with more than 140 separate footnotes, as well as sidebars that profiled the shooter, Seung-Hui Cho, and gave a timeline of the attacks.

According to the foundation that runs the various Wikipedias around the world, there were more than 750,000 visits to the main article on the shootings in its first two days, an average of four visits a second. Even The Roanoke Times, which is published near Blacksburg, Va., where the university is located, noted on Thursday that Wikipedia “has emerged as the clearinghouse for detailed information on the event.”

Recently, Wikipedia had been the object of much controversy over the reliability of the its articles, and the frequent anonymity of its contributors. But during some recent critical events, like the Virginia Tech killings, the Southeast Asian tsunami in 2004, and the London bombings in 2005, the site has been transformed from an ever-growing reference book into a ever-updating news source — albeit one with scant original reporting. (Wikipedia’s policy precludes original research.)

“Professional news is the place to get the facts on the ground — after all, that’s where Wikipedia contributors are getting their information, too,” said Michael Snow, a Wikipedia administrator. “Wikipedia distinguishes itself by the ability to bring all the facts, and useful background information, together in one place.”

In interviews, some of the most prolific contributors about the Virginia Tech shootings said they were at a loss to explain how everything manages to come out as well as it does.

Miikka Ryokas, whose user name is Kizor and in an e-mail message said that he was a 22-year-old computer science student from Turku, Finland, wrote: “As the popular joke goes, ‘The problem with Wikipedia is that it only works in practice. In theory, it can never work.’ ”

Mr. Ryokas wrote that he had spent 15 hours on the article, mostly to “tag dubious information with ‘citation needed’ or remove it entirely” and to “restore valid information that is accidentally lost.”

“I get involved when a major tragedy strikes,” he wrote. “I may not be able to help the victims, but I can, and therefore must, do a small part in helping accurate information get through to the world.”

Sir Ken Robinson: Do schools kill creativity?

If you have about 20 minutes and you are at all interested in education, you will want to take a look at this.

Sir Ken Robinson makes an entertaining (and profoundly moving) case for creating an education system that nurtures creativity, rather than undermining it. With ample anecdotes and witty asides, Robinson points out the many ways our schools fail to recognize — much less cultivate — the talents of many brilliant people. “We are educating people out of their creativity,” Robinson says. The universality of his message is evidenced by its rampant popularity online.

A special bond

There was a great story today in the Atlanta Journal-Constitution about a disabled man and his deaf dog, with whom he communicates by sign langauge.

One of them weighs 195 pounds, walks on four legs and can’t hear. The other has only one hand and communicates with sign language. And whenever they go to Piedmont Park, they draw a crowd.

Jeremy Coty and his dog Connor can be found three or four days a week at the Piedmont Dog Park, along with Coty’s other two dogs. And everyone in the off-leash area seems to gravitate to the outgoing guy and his enormous dog. We’re talking really big. On his hind legs, Connor stands 6 feet, 6 inches tall.

Connor is deaf and responds to about 10 signed words and commands. When he’s a good boy, Coty rubs his chest or claps. When Coty wants the dog’s attention, he shapes his hand like a “C” for “Connor.” When Connor gets too aggressive in a game of tug of war, Coty shakes two fingers back and forth and Connor backs away.

Coty and Connor share a special bond because they have a couple things in common. For one, Coty joked, they’re both Aries. For another, they both have a disability.

Coty, 36, was born with a defect that left him with what he calls a “little arm” that has no fingers.

As for Connor, “if he was born with his hearing, he likely lost it during the first week of his life, so he doesn’t have recollection of it,” Coty said. “I’m the same.

“I’ve always gravitated toward people and animals who don’t fit the mold of what we view as ‘normal,’” he said.
