Dolphins' Hunting Technique Inspires New Radar Device 79

minty3 writes "The twin inverted pulse radar (TWIPR) made by a team from the University of Southampton in England uses the same technique dolphins do to capture prey. Like dolphins, the device sends out two pulses in quick succession to cancel out background noise. The findings, published in the journal Proceedings of the Royal Society A: Mathematical and Physical Sciences, explained how the device resembles the way dolphins send out two pulses in quick succession to cancel out background noise."

Maybe the Cubans could give the game platform to Viet Nam, and they could come up with a plotline where you follow Ho Chi Min to his defeat of the imperialist US invaders. There's jungles and tropical climate in both situations, right.

Researchers Find Crippling Flaws In Global GPS 179

mask.of.sanity writes "Researchers have developed attacks capable of crippling Global Positioning System infrastructure critical to the navigation of a host of military and civilian technologies including planes, ships and unamed drones. The novel remote attacks can be made against consumer and professional-grade receivers using $2500 worth of custom-built equipment. Researchers from Carnegie Mellon University and Coherent Navigation detailed the attacks in a paper. (pdf)"

You were hired because you best convinced the people reviewing and interviewing you that you were the right fit for the job. Whether you woke up extra early to be fresh for the interview, wore a pressed suit, or took attention-focussing drugs with breakfast, ideally you're being judged not just on how well you showed up that day, but how well your history appears to fit their requirements.

You can certainly make an extra effort to get a job that you don't intend to make once you have a job. That could just as easily mean no longer shaving as it could mean no longer buying the appropriate smart-pills. The smart-pills are not the problem here, they're merely another tool in an already-well equipped box. If you fall below the requirements of the job after starting, then that's what the probation period (or performance reviews, later) is for.

Of course, if a company insists on judging all its hirees by one particular metric that can be temporarily enhanced to secure a job, then they may have a problem. But the problem is not the temporary enhancement...

It sounds like you think the other team is "people who do the things necessary to secure that job". I'm not sure that job-hunting is or should be a level playing field, and it's not really a 'team competition' so much as 'every person for himself or herself'. The idea being to find the best people, not "the best people if you eliminate certain variables".

I don't see what foreign workers have to do with anything, that looks like a furphy to me, and I'm going to ignore it, because it also smells like an opportunity for a completely different disagreement.

The difference presumably being that in sport, you're playing within a specific and arbitrary set of limitations, one of which is currently held to be a limitation on artificial enhancement. Same as you're not allowed to to trip your competitors up in a foot-race.

If you're actually doing stuff where you're not being measured in some sort of specific playing field or situation, why not be able to do what its necessary (and non-harmful) to do that as well as possible.

I'm not required to listen to the same music as my colleagues, or drink coffee when I work, after all. We're not trying to level the playing field, we're all trying to individually excel so that our group as a whole excels.

This is the strawman in the final comment: "So another question for the ethicists is whether cognitive enhancers will ultimately level the playing field or juice the opposing team". Who's my opposing team? Am I required to only work as well as... who? And if so, then... why? Why would I only be allowed to do my job as well as someone else could?

The implicit idea seems to be that there's those who're sub-normal, for whom it's alright to make them normal (be fixed), and then those who're super-normal, who're just lucky and aren't allowed to be made any better (be enhanced).

I haven't read the article yet, so these questions may already have been answered.

Comment Not sexist. Worse. (Score 1) 897

It's not sexist. It's not discriminating against a particular sex. It's creating an uncomfortable and exclusive environment to the detriment of those of any gender who feel that references to "big boobs" are unprofessional or inappropriate appearing in code like that.

If you did it in in a work environment, it'd be harassment.

It's really more insidious than sexism. It's easy to spot sexism, but trying to explain the ways in which this example is a bad thing will inevitably produce responses of "you're over-sensitive" from people who are not offended by it.

By calling it merely "sexist", it automatically excludes from the discussion any _males_ who find it offensive, as they must be obviously offended on some woman's behalf, not because they find it offensive themselves, and are therefore not vested in the results. (And may well be derided as taking that position merely to get into said woman's pants, which is another great example of things that are not sexist but are still incredibly bad behaviour in a professional environment.)

In Australia, you pay income tax on money you make in Australia even after you've lived overseas for six months.

However, Australia has a fairly wide coverage of Double Taxation agreements, which means (usually) once you become a tax resident of another country (more than half of the year spent living there, etc.) the tax you pay in Australia counts towards the tax you'd owe in the country of residence, so in effect you pay the greater of "Australian tax on Australian income" and "foreign-country tax on worldwide income".

Which normally means that any income tax withholding done for you in Australia is tax you'd have to pay anyway to your country of residence, so it just avoids you getting a surprise giant tax bill once a year.

This includes one with the US, although I haven't looked at the details of it to see if it covers US citizens resident in Austalia.

Monkeypox Scare Grounds Flight In Chicago 109

Hugh Pickens writes "AP reports that when a Delta Airlines flight touched down at Midway International Airport in Chicago, the passengers looked out the window to see the jet surrounded by fire trucks, police cars and ambulances. Health officials came through the door wearing facemasks and other protective gear. As it turns out the bedbugs that infest hotels appear to be the source of red marks on a 50-year old Minnesota woman that prompted health officials to quarantine the jet for fear they were dealing with something much more serious: monkeypox. Lise Sievers called her mother during a layover in Detroit and told her that one of the children she visited and is trying to adopt in Uganda had some pus-filled red bumps and also mentioned she had some small bumps of her own, a rash that she suspected was the handiwork of bedbugs. Those two very different bumps — one with pus, one without — got jumbled up in Siever's mother's mind, and she called a hospital near her Indiana home to ask about treatment for her daughter. 'She told them her daughter is on a flight back from Uganda and has some red bumps which are pussing and what should she do to treat them,' says Roger Sievers. 'She was looking for some general advice.' Health officials feared they were looking for monkeypox, a rare and sometimes fatal disease mostly in found in central and western Africa. After the passengers waited on the plane for a couple of hours, officials brought good news. 'They came back down and told my mom it was bed bug bites and they started releasing people.'"

I always find it amazing that electronic gadgets are a "distraction" yet non-electronic ones are not. You don't see legislation to outlaw paper maps, coffee cups, makeup, food, etc from vehicles.

"...yet..."

It's a slow process, because the longer something's been legal, the harder it is to get a law passed to make it illegal, irrespective of the actual damage.

They managed to make it illegal to have open bottles of booze in a car, tied in nicely with the invention of random breath testing. Smoking too, in some places so far. Drivers eating and drinking can't be _too_ far off.

If I had to guess, I'd say it _is_ illegal to look at and/or manipulate a paper map while driving. Something about blocking the view of the road, most likely.

The highest hurdle will be making it illegal to talk to the driver while they're driving, since that was (as I recall) demonstrated in the UK as being just as dangerous as the driver using a hands-free kit, in so far as distraction was a major problem, and operating a hands-free kit was relatively minor problem.

I expect we'll have self-driving cars before that, and this ceases to be a problem... Once we have self-driving cars, just make getting a car license really really really hard, and expire them (completely) every five years.

Once a generation of teenagers ages to adulthood without the car and driver's license being a major part of their coming-of-age, it won't be a problem any more.
