Russians to send bogus navigation data to thousands of ships
The Russians have started hacking into the global navigation satellite system (GNSS) on a mass scale in order to confuse thousands of ships and aeroplanes about where they are. GNSS comprises the constellation of international satellites that orbit the earth. The US’s Global Positioning System (GPS), China’s Beidou, Russia’s GLONASS, and Europe’s Galileo program are all part of GNSS.
Your phone, law enforcement, shipping, airlines, and power stations – anything dependent on GPS time and location synchronisation – are all vulnerable to GNSS hacking. An attack that disabled GNSS in Britain would cost about £1 billion every day the system was down. The jamming, blocking, or spoofing of GNSS signals by the Russian government is “more indiscriminate and persistent, larger in scope, and more geographically diverse than previous public reporting suggested.”
Russian forces had developed mobile GNSS jamming units to provide protection for the Russian president. The incidents also align with the locations of Russian military and government resources. Ships sailing near Gelendzhik have reported receiving bogus navigation data on their satellite systems.
Most of the incidents have been recorded in Crimea, the Black Sea, Syria, and Russia. Perhaps more disturbingly, GNSS spoofing equipment is available to almost anyone, for just a few hundred dollars. Since then the cost of a GNSS spoofing device has fallen to about $US300, C4AD says, and some people have been using them to cheat at Pokemon Go.
The cofounder of MoviePass recounts what led to his firing
MoviePass cofounder Stacy Spikes admits he was not a happy camper a few months after Helios and Matheson Analytics bought MoviePass in summer 2017. MoviePass is focus on movie-ticket subscription. The app was evolving with the times and slowly growing in popularity among moviegoers, with the price point ranging from $US12 a month to up to $US75 (which included access to 3D and IMAX showings).
Ultimately the proposal from Helios and Matheson Analytics came in at $US25 million for 51% of the company. And it said they wanted to temporarily drop the subscription price to $US10 to help climb up to 100,000 subscriptions. In August of that year, the $US10-a-month to see a movie a day deal was launched and MoviePass hit 100,000 subscribers in 48 hours.
By December, Spikes said the company was growing at a quarter million subscribers a month. Spikes said he and the leadership “just disagreed on the approach.” “The good side was cinema had not been taken seriously since Netflix really got its footing,” Spikes said. “So what I liked about that was this had risen to the zeitgeist of conversation. 75% of our members were under the age of 26. Cinema was an event people cared about again.
South Korea's president lost 12 of his teeth from stress
South Korea’s President Moon Jae-in has presided over a historic warming of relations with its nuclear neighbour, North Korea, as well as some of the most high-stakes nuclear and military negotiations in history. But the pressure of work life in Seoul caused him to lose many of his teeth due to stress.
For reference, South Korean presidential terms last five years, but Sun was told to expect she’d only last one year. South Koreans notoriously work hard, sometimes to the point of working themselves to death. South Koreans on average work more hours per year than any country besides Mexico.
Experts blame a cultural embrace of hard work and poor information about workers’ rights for the lethal hours put in by South Koreans. While South Korea’s economy has advanced past manufacturing, technology keeps workers plugged in around the clock. While stress may not outright or directly cause the loss of teeth, it can contribute. Under extreme stress, people may grind their teeth, stop caring for their teeth as much, and stand at greater risk of gum disease.
