jones_supa writes: He might hate the United States, but he sure digs those designed-in-California computers. You probably wouldn't take Kim Jong-un as a Mac user. Usually, in photos of him checking out military computers, we see the North Korean dictator in front of a PC with a Dell monitor. However, a handful of photos of the supreme leader at his own desk show him with Macs, leading to the assumption that while the military may use PCs, his personal preference is Mac. Reuters correspondent James Pearson, who covers both Koreas, tweeted out a fresh image of little Kim using a MacBook Pro inside an aircraft. There are other images, including a 2013 image of Kim Jong-un at his desk with an iMac. That same year, the South Korean newspaper Chosun published a photo from North Korean Central News Agency, which features an Apple iMac. This might also explain why the country's home-grown Linux distribution Red Star imitates OS X.Read Replies (0)

HughPickens.com writes: Greg Milner writes in the NYT that an American tourist in Iceland directed the GPS unit in his rental car to guide him from Keflavik International Airport to a hotel in nearby Reykjavik, and ended up 250 icy miles away in Siglufjordur, a fishing village on the outskirts of the Arctic Circle. Mr. Santillan apparently explained that he was very tired after his flight and had "put his faith in the GPS." In another incident, a woman in Belgium asked GPS to take her to a destination less than two hours away and two days later, she turned up in Croatia. Finally disastrous incidents involving drivers following disused roads and disappearing into remote areas of Death Valley in California have became so common that park rangers gave them a name: "death by GPS." "If we're being honest, it's not that hard to imagine doing something similar ourselves" says Milner. "Most of us use GPS as a crutch while driving through unfamiliar terrain, tuning out and letting that soothing voice do the dirty work of navigating."
Could society's embrace of GPS be eroding our cognitive maps? Julia Frankenstein, a psychologist at the University of Freiburg's Center for Cognitive Science, says the danger of GPS is that "we are not forced to remember or process the information — as it is permanently 'at hand,' we need not think or decide for ourselves." "Next time you're in a new place, forget the GPS device. Study a map to get your bearings, then try to focus on your memory of it to find your way around. City maps do not tell you each step, but they provide a wealth of abstract survey knowledge. Fill in these memories with your own navigational experience, and give your brain the chance to live up to its abilities."Read Replies (0)

Andy Nicholls has been an R programmer and consultant for Mango Solutions since 2011 (where he currently manages the R consultancy team), after a long stint as a statistician in the pharmaceutical industry. He has a serious background in mathematics, too, with a Masters in math and another in Statistics with Applications in Medicine. Andy has taught more than 50 on-site R training courses and has been involved in the development of more than 30 R packages; he's also a regular contributor to events at LondonR, the largest R user group in the UK. But since not everyone can get to London for a user group meeting, you can get some of the insights he's gained as an R expert in Sams Teach Yourself R In 24 Hours (available in print or at Safari), of which he is the lead author. Today, though, you can ask Andy about the much-lauded statistics-oriented free software (GPL) language directly -- Why to use it, how to get started, how to get things done, and where those intriguing release names come from. (The about page is helpful, too.) As usual, please ask as many questions as you'd like, but one question at a time, please.Read Replies (0)
