DARPA’s Shredder Challenge is solved ahead of schedule

At the end of October, DARPA (the Defense Advanced Research Projects Agency) launched its Shredder Challenge contest. The objective: create a system for reconstructing shredded papers, then demonstrate it by piecing together five documents, the shredded remains of which were posted on the contest’s website.
Although the contest had a December 4th deadline, the “All Your Shreds Are Belong to U.S.” team correctly reassembled all five documents with two days to spare.
The San Francisco-based team, which beat out approximately 9,000 competitors, used “custom-coded, computer-vision algorithms to suggest fragment pairings to human assemblers for verification.” Members of the team spent approximately 600 man-hours developing algorithms and otherwise working on the challenge, completing everything within 33 days. Because it was able to reconstruct all five documents posted in the contest, the team was able to claim the complete prize of $50,000.
DARPA hosted the contest both to develop methods of reading shredded documents left behind by enemies in war zones, and to identify ways in which U.S. shredded documents could be read by other parties, so that countermeasures could be developed.
They still run the risk of Congress reducing funding for an agency that makes it possible to reassemble bits and pieces of evidence like this.
Shrinking the size of tests – and their cost – down to pennies

While other scientists successfully shrank beakers, tubes and centrifuges into diagnostic laboratories that fit into aluminum boxes that cost $50,000, George Whitesides had smaller dreams. The diagnostic tests designed in Dr. Whitesides’s Harvard University chemistry laboratory fit on a postage stamp and cost less than a penny.
His secret? Paper.
His colleagues miniaturized diagnostic tests so they could move into the field with tiny pumps and thread-thin tubes. Dr. Whitesides opted for a more novel approach, reasoning that a drop of blood or urine could wick its way through a square of filter paper without any help.
And if the paper could be etched with tiny channels so that the drop followed a path, and if that path were mined with dried proteins and chemically triggered dyes, the thumbnail-size square could be a mini-laboratory — one that could be run off by the thousands on a Xerox machine.
Diagnostics for All, the private company Dr. Whitesides founded four years ago here in Boston’s Brighton neighborhood to commercialize his inspirations, has already created such a test for liver damage. It requires a single drop of blood, takes 15 minutes and can be read by an untrained eye: If a round spot the size of a sesame seed on the paper changes to pink from purple, the patient is probably in danger.
Using paper in diagnostic tests is not entirely new. It soaks up urine in home pregnancy kits and blood in home diabetes kits. But Dr. Whitesides has patented ways to control the flow through multiple layers for ever-more-complex diagnoses. His test has proved more than 90 percent accurate on blood samples previously screened by the laboratory of Beth Israel Deaconess Medical Center, a Harvard teaching hospital, said Una S. Ryan, chief executive of Diagnostics for All…
The initial target audience is AIDS patients with tuberculosis who must take powerful cocktails of seven or more drugs. Some drugs damage the liver, and deaths from liver failure are 12 times as common among African AIDS patients as among American ones, Dr. Ryan said, because current liver tests are expensive and require tubes of blood…
RTFA. Truly worthwhile effort, starting with grants from the Bill and Melinda Gates foundation and carrying through to government assistance both sides of the pond.
Taking the cost of tests from dollars to pennies makes them affordable in the 3rd World – as well as the growing pool of poverty in the industrial West. Many examples, many goals already met. The sort of medical research that doesn’t make billions for pharmaceutical giants; but, helps human beings worldwide.
Bureaucrats unable to print tax reminder letters – no paper!

HM Revenue and Customs was due to send out millions of reminder letters to those who owed monies to be paid by July 31. But several hundred thousand people have still not received the reminders after HMRC officials failed to order enough paper on which to print the letters.
Officials apologised for the error and insisted that no one would be left out of pocket as those who did not receive reminders would be given an extra 30 days to pay without incurring interest charges…
An HMRC spokesman said: “Due to exceptionally high demand this year we are experiencing delays in sending paper self assessment tax statements to customers.
“This in no way prevents the accurate payment of tax and no one will be out of pocket as a result…”
“We very much regret any inconvenience and will send paper statements to everyone who should have one as soon as possible.”
I admit it. I love how polite Brits can be when they know the cock-up is their own fault.
Reminds me of the time an immigration piglet at Gatwick snorted Woolite I had in my backpack. He was convinced he was going to catch me smuggling drugs.
Gave me the most polite apology – after bubbles stopped popping out of his nose.
Paper books are dead – says renowned publisher
The prince of coffee table books believes paper books are dead. Now he wants to be king of the app.
Since 1980, Nicholas Callaway has made the finest of design-driven books, building a publishing house and his fortune on memorable children’s stories and on volumes known for the fidelity of their reproductions of great art. But the quality of paper, ink and binding mean nothing to him now.
For Callaway, it’s all about apps — small applications sold in Apple’s App Store where books are enhanced beyond the mere text of e-books. In this cutting-edge new medium, cooks can clap hands to turn pages of an interactive recipe, a book about Richard Nixon can include footage of him sweating during presidential debates, a Sesame Street character can read a story out loud and, should your child get bored, the app can turn the tale into a jigsaw puzzle or a computerized finger-painting set.
“I have bet the whole ranch on this,” Callaway told Reuters. “This kind of juncture happens maybe once in a century.”
Publishers from New York to London agree this as a moment of huge change. They are adapting to rising sales of e-books, and the popularity of smart phones and tablets such as the iPad. The retail landscape has changed with Amazon becoming the dominant seller of books while countless book stores go the way of video rental stores. America’s No. 2 book store chain, Borders, is bankrupt. Some authors have dropped their publishers entirely, self-publishing online and using social media to connect with readers. Others have become adept at using Facebook and Twitter to reach readers or have attracted fans by becoming popular reviewers of books on Amazon and then publishing their own book.
Callaway is among those who believe the change is just beginning and, in the years to come, the app will change things utterly.
RTFA. Several pages of history, analysis and commentary – decision and the courage to follow that decision to its logical new beginning.
For my part, I think he’s right. Though few have followed through on the breadth of editing and presentation techniques made available by digital media, what I have seen approaches a qualitative change in communication.
Everything a book can offer and more. All the rest is cultural accommodation.
Saskatchewan cabinet members are getting iPads
Saskatchewan’s 18 cabinet ministers and five senior government officials are being issued iPad tablet computers in an effort to reduce paper consumption.
In Canada, the 3G models with 64 GB of memory cost $879 each, plus recycling fees and taxes.
While the initial outlay for the province is about $23,000, an official said double that amount will be saved in the cost of printing and courier costs after just one year.
“In my office alone, as this gets rolled out, I will save 68 boxes of paper in my office a year,” Rick Mantey, a senior official in the premier’s office, told CBC News. “We’re [also] saving on courier costs. That’s going to go down, from my office, by $8,000, $9,000 a year.”
Mantey said that in a typical week, a single cabinet minister could be loaded down with six to 10 kilograms of documents.
I’ll have to ask a couple of my geek mates in the GWN how well they think their government does on computer security?
The wifi bit should be reasonable enough to take care of; but, I imagine they will need to add an app layer to lock things tighter than a simple 4-character login.
Pretty interesting about how much paper they expect to replace + couriers.
First paper ‘dipstick’ test for determining blood type
Scientists are reporting development of the first “dipstick” test for instantly determining a person’s blood type at a cost of just a few pennies. Their study on the test, which involves placing a drop of blood on a specially treated paper strip, appears in ACS’ semi-monthly journal Analytical Chemistry: “Paper Diagnostic for Instantaneous Blood Typing”, where the authors say it could be a boon to health care in developing countries. The test also could be useful in veterinary medicine, for typing animals’ blood in the field, they note.
Gil Garnier and colleagues explain that determining a patient’s blood type is critical for successful blood transfusions, which save millions of lives each year worldwide. There are four main blood types: A, B, AB, and O. Use of the wrong blood type in a patient can be fatal. Current methods for determining blood type require the use of sophisticated instruments that are not available in many poor parts of the world. An inexpensive portable test could solve that problem.
The scientists describe development of prototype paper test strips impregnated with antibodies to the antigens on red blood cells that determine blood type. In lab tests using blood samples from human volunteers, the scientists showed that a drop of blood placed on the strip caused a color change that indicated blood type. The results were as accurate as conventional blood typing. “The paper diagnostics manufacturing cost is a few pennies per test and can promote health in developing countries,” the report notes.
Bravo!
New world record for folded paper plane flight

With a bend of the knees and an arch of the back, a Japanese engineer today set a world flight record for a paper plane, keeping his hand-folded construction in the air for 26.1 seconds.
Using a plane specially designed for “long haul” flights, Takuo Toda narrowly failed to match his lifetime best of 27.9 seconds, a Guinness world record set in Hiroshima earlier, but achieved with a plane that was held together with cellophane tape.
Today’s flight, inside a Japan Airlines hangar near Haneda airport in Tokyo, was the longest by an unadulterated model. “I felt a lot of pressure,” Toda told the Associated Press after his feat. “Everything is a factor ‑ the moisture in the air, the temperature, the crowd.”
The record was all the more satisfying for having been achieved with a plane that stayed true to the traditions of origami, the traditional Japanese art of paper folding. He folded his 10cm aircraft by hand from a single sheet of paper and did not use scissors or glue…
He will again try to achieve the origami plane equivalent of Roger Bannister’s sub-four-minute mile: keeping his plane aloft for a full half a minute.
“I will get the 30-second record,” he said. “It’s just a matter of time.”
Bravo!
