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.
When President Obama left, I stayed on at the National Security Council in order to serve my country. I lasted eight days.
In 2011, I was hired, straight out of college, to work at the White House and eventually the National Security Council. My job there was to promote and protect the best of what my country stands for. I am a hijab-wearing Muslim woman––I was the only hijabi in the West Wing––and the Obama administration always made me feel welcome and included.
Like most of my fellow American Muslims, I spent much of 2016 watching with consternation as Donald Trump vilified our community. Despite this––or because of it––I thought I should try to stay on the NSC staff during the Trump Administration, in order to give the new president and his aides a more nuanced view of Islam, and of America's Muslim citizens.
You can tell a lot about a person from how they react to something.
That’s why Facebook’s various “Like” buttons are so powerful. Clicking a reaction icon isn’t just a way to register an emotional response, it’s also a way for Facebook to refine its sense of who you are. So when you “Love” a photo of a friend’s baby, and click “Angry” on an article about the New England Patriots winning the Super Bowl, you’re training Facebook to see you a certain way: You are a person who seems to love babies and hate Tom Brady.
The more you click, the more sophisticated Facebook’s idea of who you are becomes. (Remember: Although the reaction choices seem limited now—Like, Love, Haha, Wow, Sad, or Angry—up until around this time last year, there was only a “Like” button.)
Long after research contradicts common medical practices, patients continue to demand them and physicians continue to deliver. The result is an epidemic of unnecessary and unhelpful treatments.
First, listen to the story with the happy ending: At 61, the executive was in excellent health. His blood pressure was a bit high, but everything else looked good, and he exercised regularly. Then he had a scare. He went for a brisk post-lunch walk on a cool winter day, and his chest began to hurt. Back inside his office, he sat down, and the pain disappeared as quickly as it had come.
That night, he thought more about it: middle-aged man, high blood pressure, stressful job, chest discomfort. The next day, he went to a local emergency department. Doctors determined that the man had not suffered a heart attack and that the electrical activity of his heart was completely normal. All signs suggested that the executive had stable angina—chest pain that occurs when the heart muscle is getting less blood-borne oxygen than it needs, often because an artery is partially blocked.
Since the middle of last year, a group of Filipino reporters, photographers, and cameramen have been at the frontline of Philippine President Rodrigo Duterte’s war on drugs. They are a different type of war correspondent, and the drug war, a different type of war.
The correspondents work what they call the “night shift,” the unholy hours between 10 p.m. and 5 a.m., when the dead bodies are found. They wait at Manila’s main police station and rush from there to the site of the most recent kill. They keep count of the corpses, talk to witnesses and families, interview the police, attend wakes and funerals. A lot of what the world learned about the carnage, especially in the early months, is due largely to the night shift reporters.
“No… it’s a magic potty,” my daughter used to lament, age 3 or so, before refusing to use a public restroom stall with an automatic-flush toilet. As a small person, she was accustomed to the infrared sensor detecting erratic motion at the top of her head and violently flushing beneath her. Better, in her mind, just to delay relief than to subject herself to the magic potty’s dark dealings.
It’s hardly just a problem for small people. What adult hasn’t suffered the pneumatic public toilet’s whirlwind underneath them? Or again when attempting to exit the stall? So many ordinary objects and experiences have become technologized—made dependent on computers, sensors, and other apparatuses meant to improve them—that they have also ceased to work in their usual manner. It’s common to think of such defects as matters of bad design. That’s true, in part. But technology is also more precarious than it once was. Unstable, and unpredictable. At least from the perspective of human users. From the vantage point of technology, if it can be said to have a vantage point, it's evolving separately from human use.
Meet the protesters who tricked conference attendees into waving Russian flags.
Two men made trouble—and stirred up a social-media frenzy—on the third day of the Conservative Political Action Conference by conducting a literal false-flag operation.
Jason Charter, 22, and Ryan Clayton, 36, passed out roughly 1,000 red, white, and blue flags, each bearing a gold-emblazoned “TRUMP” in the center, to an auditorium full of attendees waiting for President Trump to address the conference. Audience members waved the pennants—and took pictures with them—until CPAC staffers realized the trick: They were Russian flags.
The stunt made waves on social media, as journalists covering CPAC noticed the scramble to confiscate the insignia.
The preconditions are present in the U.S. today. Here’s the playbook Donald Trump could use to set the country down a path toward illiberalism.
It’s 2021, and President Donald Trump will shortly be sworn in for his second term. The 45th president has visibly aged over the past four years. He rests heavily on his daughter Ivanka’s arm during his infrequent public appearances.
Fortunately for him, he did not need to campaign hard for reelection. His has been a popular presidency: Big tax cuts, big spending, and big deficits have worked their familiar expansive magic. Wages have grown strongly in the Trump years, especially for men without a college degree, even if rising inflation is beginning to bite into the gains. The president’s supporters credit his restrictive immigration policies and his TrumpWorks infrastructure program.

Students can learn the basics with a set of knitting needles.
The Finns are pretty bemused by Americans’ preoccupation with whether to put iPads in every classroom. If a tablet would enhance learning, great. If it wouldn’t, skip it. Move on. The whole thing is a little tilting-at-windmills, anyway.
That was the gist of the conversation one recent morning at the Finnish Embassy in Washington, D.C., where diplomats and experts gathered to celebrate the country’s education accomplishments as Finland turns 100. And Americans could stand to take notes. (Yes, from Finland—again.)
Coding and programming are now part of the curriculum in the Scandinavian country, and they’re subjects kids tackle from a young age. But unlike in some parts of the United States where learning to code is an isolated skill, Finnish children are taught to think of coding and programming more as tools to be explored and utilized across multiple subjects.
Ambitious young Republicans at CPAC are torn over embracing the new nationalism of the president.
OXON HILL, Maryland — If you want to take the temperature of the conservative movement at CPAC, you need to know where to stick the thermometer. It’s not in the onstage speeches, or the myriad policy panels, or the boozy after-parties—it’s inside Exhibit Hall D on the ground floor of the Gaylord National Resort and Convention Center.
Here, in what conference organizers have dubbed “The Hub,” hundreds of blue-blazered and high-heeled young conservatives roam the cavernous hall—crammed with booths set up by right-wing think tanks, media outfits, pressure groups, and publishers—shopping for future careers. The general vibe is that of a trade show, with attendees perusing pamphlets about D.C. internships, swapping Twitter follows, and taking selfies with minor cable news celebrities. They buy t-shirts with cheeky messages on them (“God is great, beer is good & liberals are crazy”), and the lucky ones make off with a satchel full of swag (the Sheriff David Clarke bobblehead was a particularly hot item this year).
Priming kids to expect rewards for good behavior can harm their social skills in the long term.
After working with thousands of families over my years as a family psychologist, I’ve found that one of the most common predicaments parents face is how to get kids to do what they’re asked. And one of the most common questions parents ask is about tools they can use to help them achieve this goal.
One such tool is the sticker chart, a type of behavior-modification system in which children receive stickers in exchange for desired behaviors like brushing their teeth, cleaning their room, or doing their homework. Kids can later “spend” their accrued stickers on prizes, outings, and treats.
Though data on how widely sticker charts are used (and when and why they became so popular) is difficult to find, anecdotal evidence suggests that these charts have become fairly commonplace in American parenting. Google searches for “sticker chart,” “chore chart,” and “reward chart” collectively return more than 1 million results. Amazon has more than 1,300 combined product results for the same searches. Reddit, too, is teeming with forums for parents asking each other about the merits of the charts and discussing specific strategies.
