That's the argument made by computer scientists M.P.Sivaram Kumar and S. Rajasekaran in a recent article in the Journal of Computing entitled "Path Planning Algorithm for Extinguishing
Forest Fires." Their thesis is simple: the vast majority of forests are destroyed by wild forest fires, and current methods of sylvan vigilance -- mainly those involved individual personnel on foot patrol -- are grossly inefficient in identifying emerging threats. Their pre-defined route may be damaged or obscured, inclement weather affects visibility, and life on patrol is boring and "miserable," leading to a lack of attention.
Kumar and Rajasekaran argue that deploying robotic systems throughout wooded areas will increase firefighters' ability not just to identify emerging threats, but also to more effectively plot the path of a wildfire, and then deploy the appropriate resources to the right places. The two imagine a grid-based system of automated drones, designed to detect abnormal changes in temperature and relay data back to a command center:
The automatic forest fire detection and extinguishing system consists of
nodes deployed deterministically in a forest area and all
the nodes know their location based on coordinate values
of a matrix. Each node is equipped with a temperature
sensor and an Omni directional antenna. Nodes continuously monitor the environment to check if there is fire or
not in the particular cell. When change in temperature i.e.
temperature raises above a certain threshold, is detected
by a particular node they send message packets which
contain location measurements. These packets are received by one of the corner node. The corner node then
sends the packet to the Actor which in turn will process
the packet which can be used in reaching the target area
to extinguish fire.
On-the-ground nodes, they argue, are significantly better than the preexisting satellite detection systems that, due to a long scan period and low resolution of images, end up detecting fires relatively late. Relying on satellites often means that firefighting personnel deploy more resources in their firefighting than would otherwise be necessary.
There are obvious environmental concerns to stringing a sprawling forest with robotic nodes. Introducing any man-made object, even stationary a drone, can have unintended consequences on a complex arboreal ecosystem. Unexpected costs -- a tree falling in the woods, surprise visits from assorted large mammals -- could make deploying and maintaining a robotic grids prohibitively expensive.
But among the significant additional benefits: potentially saving lives. Wireless Emergency Alerts (WEA), a system developed by FEMA, the FCC, and wireless carriers, will soon be deployed in emergency situations like severe weather to notify citizens of imminent threats to their safety. Within the next few weeks, nearly everyone in the country with a mobile phone could start receiving text messages from the National Weather Service, local law enforcement, or perhaps even the President. Here's how it works:
In the event of an emergency, an authorized alerting agency can select a cell tower (or towers) to broadcast a WEA. In order to receive the message, a person must be within range of the cell-tower broadcast, and must have a phone capable of "hearing" the the broadcast. Most cellular devices manufactured after mid-2011 already have this capability.
It is through the use of CB technology that CMAS is able to provide some geographic targeting without the need for opting-in. However, it is important to note that because WEAs are "broadcast" from towers, the geo-targeting feature is not as precise as GPS. GPS is a two-way street of communication between a GPS-equipped device and various positioning satellites. WEAs are not two-way...it is simply a modern day "shout" to give a heads-up that something requires your attention.
According to the National Fire Protection Association, only 11 people were killed in wildfire-related incidents in 2011. But application of the sensor technology to, say, rivers with a high likelihood of flooding, earthquake-prone regions, and other unstable natural centers could give first responders a useful heads-up. When tied in with FEMA's new WEA system, average citizens could have enough advance warning of danger to protect themselves in the event of a natural disaster. And in the event of a fast-moving fire or flood, a few extra minutes could mean the difference between life and death.
People look to Amy Schumer and her fellow jokers not just to make fun of the world, but to make sense of it. And maybe even to help fix it.
This week, in a much-anticipated sketch on her Comedy Central show, Amy Schumer staged a trial of Bill Cosby in “the court of public opinion.” Schumer—her character, at any rate—played the role of the defense. “Let’s remind ourselves what’s at stake here,” she argued to the jury. “If convicted, the next time you put on a rerun of The Cosby Show you may wince a little. Might feel a little pang. And none of us deserve that. We don’t deserve to feel that pang.”
Her conclusion? “We deserve to dance like no one’s watching, and watch like no one’s raping.”
Ooof. This is the kind of thing that gets Inside Amy Schumer referred to as “the most feminist show on television,” and her act in general called, in a phrase that reveals as much about her craft as about Schumer herself, “comedy with a message.” But while Schumer’s work is operating at the vanguard of popular comedy, it’s also in line with the work being done by her fellow performers: jokes that tend to treat humor not just as an end in itself, but as a vehicle for making a point. Watch like no one’s raping.
For those who didn't go to prestigious schools, don't come from money, and aren't interested in sports and booze—it's near impossible to gain access to the best paying jobs.
As income inequality in the U.S. strikes historic highs, many people are starting to feel that the American dream is either dead or out of reach. Only 64 percent of Americans still believe that it’s possible to go from rags to riches, and, in another poll, 63 percent said they did not believe their children would be better off than they were. These days, the idea that anyone who works hard can become wealthy is at best a tough sell.
Caves and tunnels have always been part of human life.
Caves and tunnels have always been part of human life. We've grown more adept at shaping these underground shelters and passages over the millennia, and today we dig for hundreds of reasons. We excavate to find both literal and cultural treasures, digging mines and unearthing archaeological discoveries. We use caverns for stable storage, for entertainment, and for an effective shelter from natural and man-made disasters. And as the planet's surface becomes ever more crowded, and national borders are closed, tunnels provide pathways for our vehicles and for smugglers of every kind. Collected below are more recent subterranean scenes from around the world.
The former speaker of the House is charged with lying to federal agents and evading financial reporting requirements in what appears to be a case of blackmail.
Former House Speaker Dennis Hastert has been indicted on charges of lying to FBI agents and evading federal financial-reporting requirements.
Hastert, an Illinois Republican, was speaker from 1999 to 2007. BuzzFeed’s John Stanton, who first reported on the indictment, notes that there were several high-profile congressional scandals in those years. Illinois is also a notorious hotbed for political corruption, as Roland Burris, Rod Blagojevich, George Ryan, and Jesse Jackson Jr. can attest.
But reading between the lines of the indictment against Hastert suggests a darker story than political corruption. In or about 2010, according to the indictment, Hastert—a former high-school teacher and coach—met with an unnamed individual from Yorkville, Hastert’s hometown. They “discussed past misconduct by defendant against Individual A that had occurred years earlier.” In effect, Hastert fell victim to blackmail, the indictment alleges: He “agreed to provide Individual A $3.5 million in order to compensate for and conceal his prior misconduct against Individual A.” (Since leaving the House, Hastert has become a highly paid lobbyist.)
What it’s like to watch a komodo dragon get dissected
Try to imagine how hard it would be to skin a Komodo dragon.
It is harder than that.
The problem is that the giant lizard’s hide is not just tough and leathery, but also reinforced. Many of the scales contain a small nugget of bone, called an osteoderm, which together form a kind of pointillist body armor. Sawing through these is tough on both arms and blades.
I’m at the Royal Veterinary College, about 20 kilometers outside of central London, watching four biologists put their shoulders into the task. A Komodo dragon, which recently died in London Zoo for unexplained reasons, lies on a steel gurney in front of them. Their task, over the next three days, is to dissect it and measure all of its muscles. So, first, the skin must come off.
New research confirms what they say about nice guys.
Smile at the customer. Bake cookies for your colleagues. Sing your subordinates’ praises. Share credit. Listen. Empathize. Don’t drive the last dollar out of a deal. Leave the last doughnut for someone else.
Sneer at the customer. Keep your colleagues on edge. Claim credit. Speak first. Put your feet on the table. Withhold approval. Instill fear. Interrupt. Ask for more. And by all means, take that last doughnut. You deserve it.
Follow one of those paths, the success literature tells us, and you’ll go far. Follow the other, and you’ll die powerless and broke. The only question is, which is which?
Of all the issues that preoccupy the modern mind—Nature or nurture? Is there life in outer space? Why can’t America field a decent soccer team?—it’s hard to think of one that has attracted so much water-cooler philosophizing yet so little scientific inquiry. Does it pay to be nice? Or is there an advantage to being a jerk?
A song from 2011 is causing controversy now, proving how slowly the genre’s attitudes about women are evolving.
The rapper Action Bronson, whose major-label debut came out recently, is mostly known for his love of food, his large frame, and the fact that he sounds so much like Ghostface Killah that even Ghostface Killah gets confused sometimes. He will likely now be known by more people for one particular lyric of his, due to a headline-making petition asking Toronto’s NXNE music festival to kick the artist off the bill because, in its words, he “glorifies gang-raping and murdering women.”
The lyrics in question come from the 2011 song, “Consensual Rape,” which has a verse that mentions giving a girl MDMA and then having very rough sex with her. The petition also calls out a 2011 music video that portrays Bronson happily disposing of a woman’s corpse.
The danger of uploading one’s consciousness to a computer without a suicide switch
Imagine a supercomputer so advanced that it could hold the contents of a human brain. The Google engineer Ray Kurzweil famously believes that this will be possible by 2045. Organized technologists are seeking to transfer human personalities to non-biological carriers, “extending life, including to the point of immortality.” My gut says that they’ll never get there. But say I’m wrong. Were it possible, would you upload the contents of your brain to a computer before death, extending your conscious moments on this earth indefinitely? Or would you die as your ancestors did, passing into nothingness or an unknown beyond human comprehension?
The promise of a radically extended lifespan, or even immortality, would tempt many. But it seems to me that they’d be risking something very much like hell on earth.
Reforms were slow to take hold in Cincinnati, but when they did, they drove down crime while also reducing arrests.
CINCINNATI—Citizens were throwing stones and beer bottles at police officers in front of City Hall, and Maris Herold didn’t understand what they wanted.
She was a police officer herself, and knew that her department had made some missteps. Most recently, an officer gunned down a 19-year-old unarmed black man, Timothy Thomas—the fifteenth black man to die at the hands of police in five years.
But, Herold knew, the police were investigating the incident. They were listening to the community. They were working 12-hour shifts to protect the city from looting and fires, though the disturbance would soon turn into the worst riots in the U.S. in a decade.
“I was like, ‘We’re doing everything right, obviously the police officers made mistakes and we’re trying to get to the bottom of it,’” she told me recently. Herold, who joined the police force after a career in social work, couldn’t understand what more the police could do to make amends with the community.
There are two types of people in the world: those with hundreds of unread messages, and those who can’t relax until their inboxes are cleared out.
For some, it’s a spider. For others, it’s an unexpected run-in with an ex. But for me, discomfort is a dot with a number in it: 1,328 unread-message notifications? I just can’t fathom how anyone lives like that.
How is it that some people remain calm as unread messages trickle into their inboxes and then roost there unattended, while others can’t sit still knowing that there are bolded-black emails and red-dotted Slack messages? I may operate toward the extreme end of compulsive notification-eliminators, but surveys suggest I’m not alone: One 2012 study found that 70 percent of work emails were attended to within six seconds of their arrival.
This has led me to a theory that there are two types of emailers in the world: Those who can comfortably ignore unread notifications, and those who feel the need to take action immediately.
