Nobody had tried to use this kind of data to try to locate an airplane before. At first, Ashton's team didn't know if the attempt would work. But painstakingly, over the course of weeks, the team figured out how the movement of the plane, the orbital wobble of the satellite, and the electronics within the satcom system all interacted to create the data values that had been received. "We had to create the model from scratch," Ashton says. Their work revealed that the plane had flown into the remote southern Indian Ocean. They didn't know where exactly. But since there are no islands in that part of the world, it was impossible that anyone could have survived. For the first time in history, hundreds of people were declared legally dead based on mathematics alone.
Then mathematician Dr. Neil Gordon led a team from the Defense Science and Technology Group "to extract a path from a subset of the Inmarsat data called the Burst Timing Offset. This measured how quickly the aircraft responded each time the satellite pinged it, and was used to determine the distance between the satellite and the plane." They ultimately generate "a probabilistic 'heat map' of the plane's most likely resting places using a technique called Bayesian analysis. These calculations allowed the DSTG team to draw a box 400 miles long and 70 miles across, which contained about 90 percent of the total probability distribution.
But even this jaded math wiz-kid couldn't help but drop his jaw, loose his tongue, and bulge his eyes at the first time Engare cracked open its math-rich heart. One early puzzle (shown above) ended with its seemingly simple pattern repeating over and over and over and over. Unlike other puzzles, this pattern kept drawing itself, even after I'd fulfilled a simple line-and-turn pattern. And with each pass of the drawing pattern, driven by a spinning, central circle, Engare drew and filled a new, bright color. This is what the game's creator is trying to shout, I thought. This is his unique, cultural perspective. This looks like the Persian rugs he saw his grandmother weave as a child.
She trained it separately on the first decade of Slashdot headlines -- 1997 through 2007 -- as well as the second decade from 2008 to the present, and then re-ran the entire experiment using the whole collection of every headline from the last 20 years. Among the remarkable machine-generated headlines?
- Microsoft To Develop Programming Law
- More Pong Users for Kernel Project
- New Company Revises Super-Things For Problems
- Steve Jobs To Be Good
One way of looking at it is that when he was designing his categories, he wanted the prizes to only reflect advances in fundamental science. In this view, "lesser" sciences such as biology, geology, or computer science -- or technology-driven fields such as engineering or robotics -- don't qualify. As genome-sequencing pioneer Eric Lander once said, "You don't get a Nobel Prize for turning a crank." But what then of literature and peace, or the newer prize for economics (an applied science at best, and a pseudoscience at worst)? Technology isn't the only field to get the cold shoulder. Mathematics -- the international language, the foundation of so many scientific pursuits, and arguably the most fundamental theoretical discipline of all -- doesn't have a Nobel Prize, either. Mathematicians have complained about this for decades. One story suggests that Nobel disliked the Finnish mathematician Rolf Nevanlinna, and assumed that he would be the first winner of the mathematics prize, if he decided to award one. Alternatively, math undergraduates are often told that Nobel was jealous of a Swedish mathematician who had an affair with his wife (though this story is ruined by the fact that Nobel didn't actually have a wife).
While tax evasion cost the U.S.$3 trillion between 2000 and 2009, one of the report's authors argues that people should be aware âoethat what they say and do onlineâ could be used against them.
"Research has shown that 'one-to-one' programs, meaning one student one computer, implemented the right way, increase student learning in subjects like writing, math and science. Those results have prompted other states, like Utah and Nevada, to look at implementing their own one-to-one programs in recent years. Yet, after a decade and a half, and at a cost of about $12 million annually (around one percent of the state's education budget), Maine has yet to see any measurable increases on statewide standardized test scores."
The article notes that Maine de-emphasized teacher training which could've produced better results. One education policy researcher "says this has created a new kind of divide in Maine. Students in larger schools, with more resources, have learned how to use their laptops in more creative ways. But in Maine's higher poverty and more rural schools, many students are still just using programs like PowerPoint and Microsoft Word."
Speaking of Microsoft, Nevada, and education, Bing Maps coincidentally shows the school Smith visited is just a 43-minute drive from the software giant's Reno-based Americas Operations Center. According to the Seattle Times, routing sales through the Reno software-licensing office helps Microsoft minimize its tax bills (NV doesn't tax business income) to the detriment, some say, of Washington State public schools.
Microsoft's state and local taxes will drop to just $30 million for the last year (from an average of $214 milion over the previous 14 years) according to the Seattle Times. "A Microsoft spokesman said the decline in 2017 was caused by the company's deferring taxes on some income to future years and the winding down of the company's smartphone business."
That tweet has since gone viral, prompting @KalebPrime to joke that "At this rate when I publish my novel the quotes will read 'FROM THE GUY THAT MADE THE WOW GOLD > VENEZUELAN BOLIVAR TWEET.'"
California, New York and Virginia still had the highest number of developers using the site, while Alaska, Wyoming and South Dakota not surprisingly had the least number of developers. But maybe the real take-away is that programmers are now becoming more distributed. HackerRank's announcement notes that the site "found growing developer communities and skilled developers all across the country. Previously, the highest concentrations of developers did not stray far from the tech hubs in California. Hawaii, Colorado, Virginia, and Nevada demonstrated the fastest growth in terms of developer activity on the HackerRank platform..." In addition, "we've had a noticeable uptick in customers across industries, from healthcare to retail and finance, with strong demand for identifying technical skills quickly."
Their conclucion? "Today, as the demand for developers goes beyond technology and as there is more opportunity to work remotely, there's a more distributed workforce of skilled developers across the nation, from the Rust Belt to the East Coast... Software developers aren't just attached to VCs, startups or Silicon Valley anymore."
Last week, at the International Conference on Sampling Theory and Applications, researchers from MIT and the Technical University of Munich presented a technique that they call unlimited sampling, which can accurately digitize signals whose voltage peaks are far beyond an ADC's voltage limit. The consequence could be cameras that capture all the gradations of color visible to the human eye, audio that doesn't skip, and medical and environmental sensors that can handle both long periods of low activity and the sudden signal spikes that are often the events of interest.
One of the paper's author's explains that "The idea is very simple. If you have a number that is too big to store in your computer memory, you can take the modulo of the number."
Facebook has already issued a statement saying that they "appreciate the important work law enforcement does, and we understand the need to carry out investigations. That's why we already have a protocol in place to respond to any requests we can.
"At the same time, weakening encrypted systems for them would mean weakening it for everyone."
