Air-Gapped Computer Hacked (Again) 78 78

An anonymous reader writes: Researchers from Ben Gurion University managed to extract GSM signals from air gapped computers using only a simple cellphone. According to Yuval Elovici, head of the University’s Cyber Security Research Center, the air gap exploit works because of the fundamental way that computers put out low levels of electromagnetic radiation. The attack requires both the targeted computer and the mobile phone to have malware installed on them. Once the malware has been installed on the targeted computer, the attack exploits the natural capabilities of each device to exfiltrate data using electromagnetic radiation.

i haven't seen Black mirror but i read the summary on wikipedia...

if her memory is wiped and she doesn't remember it the next day then what really is the point in doing it again?

she doesn't remember it, so it happening again to her isn't any additional punishment for her. to her every day is the first time. which means, really she has a one day sentence. and when/if they finally stop wiping her memory she will just wake up to find herself X days/years older and having only had this one really bad and confusing day.

ESPN Sues Verizon To Stop New Sports-Free TV Bundles 329 329

Mr D from 63 writes: ESPN isn't a fan of Verizon's new way of offering cable channels under its Fios TV service — they're now suing Verizon for it. The lawsuit comes after Verizon unveiled new bundles that allow customers to choose specific packages of channels that can be swapped every 30 days. ESPN claims this offer is not in compliance with their agreements with Verizon. In the U.S., ESPN depends heavily on viewership during the football season, then basketball. "ESPN is at the forefront of embracing innovative ways to deliver high-quality content and value to consumers on multiple platforms, but that must be done in compliance with our agreements," said an ESPN spokeswoman in a statement. "We simply ask that Verizon abide by the terms of our contracts."

why won't people own cars? just because the car is driverless it doesn't change my need to regularly commute to work, or go to the store for groceries. it really doesn't change my usage pattern for a car a whole lot. it may change where the car will be parked when i am not using it.

people say it will make taxis cheaper...wouldn't that be comparable to renting a car today? you can rent cars now without a driver attached to it and last i checked it is still cheaper for me to own a car than to rent one. and the advantage of owning it means it is always available to me. if you always rent your car and make an unscheduled trip, you run the risk of having no cars available when you want one. even if you schedule your trip in advance you risk that the rental business could already be out of cars during the time slot that you need one. ever been bumped from a flight or hotel that has been overbooked? the companies running these will want the minimum number of cars to maximize their profits, they will want to overbook them with the assumption that a certain percent will cancel their ride at the last minute, because a car sitting idle is costing them money and not making them any profit. so what if that means 1 customer is going to be late for work that day?

renting cars will have to be a lot cheaper than owning before people give up ownership, especially if they use it nearly every day like they do now.

2. Not every place everyone will want to go is paved or mapped, and mapping is not 100% accurate, so you still need periodic human intervention, or you have an arbitrarily limited car, that many people will be unlikely to accept.

if every car is equipped with GPS and other sensors, and they share the data they collect, then the quality of maps are going to improve by very quickly.

The Believers: Behind the Rise of Neural Nets 45 45

An anonymous reader writes Deep learning is dominating the news these days, but it's quite possible the field could have died if not for a mysterious call that Geoff Hinton, now at Google, got one night in the 1980s: "You don't know me, but I know you," the mystery man said. "I work for the System Development Corporation. We want to fund long-range speculative research. We're particularly interested in research that either won't work or, if it does work, won't work for a long time. And I've been reading some of your papers." The Chronicle of Higher Ed has a readable profile of the minds behind neural nets, from Rosenblatt to Hassabis, told primarily through Hinton's career.

given either enough time or distance anything not specifically prohibited by the laws of physics is happening somewhere.

if the universe were something like 10^10^100 light years across then there would be an exact duplicate of "you" somewhere in it. because there are only so many configurations and quantum states that a specific volume of space can take.

granted we don't believe our universe is that large, only i think about 10^26 light years., but given a universe that is large enough then some seemingly unlikely things could be happening in it somewhere.

Imagine you're a CPU and your perception of time is in clock cycles. Would you be able to give an ordered sequence of events of all the things that happen before your clock generator starts, e.g. voltage ramp-ups, etc?

That is a perfect example, and i think it illustrates a few things.

For the CPU time started on the first tick of its clock, but the tick of that clock is still tied to a time dimension in its parent universe. the term "Before" still makes sense when describing the sequence of events as the power button is pressed and then the electrons race through the wires to cause that first tick of the clock. now the CPU may not have adequate terms to describe this or understand what a power button or electrons are, but it is readily apparent to us as outside observers.

Being stuck inside the CPU would have a very difficult time figuring out the mechanisms that drive it. however some of our theories of quantum mechanics allow for higher dimensions and for structures to exist outside of our universe. And we even have experiments set up to look for evidence of some of these structures. such as polarization in the cosmic background radiation. if our universe isn't the outermost layer and is a brane in a higher dimensional universe, such as some versions of quantum mechanics suggest, then time may exist in some form outside of our universe. how this time works may not be entirely recognizable to us, but saying "before the big bang" could still have some meaning.

maybe another example. if i travel to the south pole of the earth i can't go south any further. however i can still travel further away from the north pole by jumping. by jumping i may not be any further south, but i could be considered less north. so what is before the universe? i don't know, lets climb to the bottom and jump and see where we end up.
