You are how you drive, we learned this week, when researchers showed how your car's computer can identify you based on patterns in your driving techniques. And it doesn't take much data to do so. Information collected from a car's brake pedal alone let the researchers distinguish the correct driver nine times out of 10. Patterns, of a different sort, also played a role in a map researchers have created to track where government hackers around the world are spying on journalists, activists, lawyers, and NGOs. And speaking of surveillance--whistleblower Edward Snowden also popped up in a Vice episode this week to show you how to make your phone "go black" so it's harder to surveil.

This post contains my answers from a Quora session I did on machine learning and artificial intelligence. Each section contains a link to the original Quora question, the overall session can be found here. Think carefully about what you actually want to achieve with it. Most fall into the latter camp, but it seems everyone fancies themselves as containing a bit of the former (particularly if they think they're going to solve AI). To do the former well, in the international community, requires really good foundations (particularly in mathematics) followed by a PhD with a supervisor who has experience of how that community works. Doing the second well is much easier from the perspective of learning machine learning. A data generator would often be a scientist or company that is working in a particular application and wants answers. They need access to machine learning researchers or statisticians to give advice on how to answer those questions. They should try and collaborate with experts in data analytics and data science, but they should be careful, there is a lot of hype around the term'big data' at the moment. It's a difficult area to navigate. Data generators typically need an interface to consume machine learning (or statistics) effectively, if this interface is poorly chosen a lot of wasted resource can result (things get very expensive very quickly for a lot of data generators!). A data consumer is where the largest demand is right at the moment, and should probably be the starting point for someone who wants to move in the right direction. An MSc in Data Science would be a good starting point. You can also use this experience to see if you want to transit into a machine learning generator (that's basically what happened to me). What are you passionate about? That is the route in to any subject. Is it a particular approach to learning or a particular application?

"The development of a special military robot is one of the priorities of military construction in Russia," the Russian daily newspaper Komsomolskaya Pravda reported recently. The purpose of Iron Man, the newspaper continued, is to "replace the person in the battle or in emergency areas where there is a risk of explosion, fire, high background radiation, or other conditions that are harmful to humans." Experts have known that Russia has been trying in recent years to match the US and China in the development of robots, drones, and other war machines that are potentially autonomous. Today, those machines are remotely controlled. Iron Man and other recent developments illustrate how they're making progress.

The recovery of the rocket module proved once again that delivering payloads into deep orbit could be much cheaper in the near future. But this idea is still in its experimental stage and would require repeated successes to become part of normal operating procedures in 21st century space transport. SpaceX plans to use one of its four recovered first-stage rockets in a mission later this year. The rocket recovery was part of a successful mission to deliver an Asian communications satellite into so-called supersynchronous orbit, a position that puts a satellite more than 22,000 miles above the earth's surface in a way where it synchronizes with the planet's orbit in order to remain above the same area at all times. The satellite, Thaicom 8, will service communications and data transfer needs in Thailand, India and East Africa, according to nasaspaceflight.com.

Dream interpretation is the process of assigning meaning to dreams. In many ancient societies, such as those of Egypt and Greece, dreaming was considered a supernatural communication or a means of divine intervention, whose message could be unravelled by people with certain powers. In modern times, various schools of psychology and neurobiology have offered theories about the meaning and purpose of dreams. Most people currently appear to interpret dream content according to the Freudian theory of dreams in countries, as found by a study conducted in the United States, India, and South Korea.[1] People appear to believe dreams are particularly meaningful: they assign more meaning to dreams than to similar waking thoughts. For example, people report they would be more likely to cancel a trip they had planned that involved a plane flight if they dreamt of their plane crashing the night before than if they thought of their plane crashing the night before or the Department of Homeland Security issued a Federal warning.[1] However, people do not attribute equal importance to all dreams.

By 2020, more than five million jobs are expected to be lost to robots and artificial intelligence. And in the next two decades, graduates will be going into jobs that don't yet exist. Anticipating this future, businesses and employers are overhauling their recruitment strategies. Job hopping has replaced the one job, one-employer career, and hybrid jobs are on the rise. Employers want recruits who have strong technical and soft skills such as empathy and flexibility.

Can software identify complex personality traits simply by analysing your face? Faception, a start-up based in Tel Aviv, Israel, courted controversy this week when it claimed its tech does just that. And not just broad categories such as introvert or extrovert: Faception claims it can spot terrorists, paedophiles – and brand promoters. "Using automated feature extraction is standard for face recognition and emotion recognition," says Raia Hadsell, a machine vision engineer at Google DeepMind. The controversial part is what happens next.

EXCLUSIVE: New satellite imagery obtained by Fox News shows that China, for the first time, has deployed a drone with stealth technology to a contested island in the South China Sea, in another sign of escalating tensions in the region. The new development comes as President Obama visits Japan. He lifted an arms embargo against Vietnam while visiting Hanoi earlier this week, drawing criticism from the Chinese government about stoking tensions in the region. The newly obtained satellite images from ImageSat International (ISI) show a Chinese Harbin BZK-005 long range reconnaissance drone on Woody Island in the South China Sea. The Chinese drone did not appear armed in the satellite image taken last month.

Golan Levin, an associate professor of art at Carnegie Mellon University, suggested. I was looking at a satellite image of the school's campus in Pittsburgh, embedded in the home page of Levin's latest online project, Terrapattern. "What you should immediately see are all the most tennis-court-ish patches of Allegheny County," he said. With gratifying speed, the right-hand side of my screen filled with dozens and dozens of tennis courts--solo or in pairs or in clusters of six, white on green, purple on green, green on red. A confusingly painted parking lot ended up in the mix, too.

The wildfire in Alberta, Canada, seems to be diminishing and residents should be able to return to the city of Fort McMurray over the next two weeks. The fire had appeared to be out of control just a few days ago but thanks to favourable weather conditions appears under control. The weather has played a huge part, but what about technology? AI, drones and satellites have all been used. Dr Guillermo Rein, from Imperial College, London and Editor-in-Chief of the journal Fire Technology explains how tech is now incorporated in fire management.
