Perhaps they mean "en-pheasant"

Thanks. That makes it more steerable (provided that the edges of the disk remain in a plane too.)

A disk 1/5 mile with a sensor 10 to 100 miles away (precisely aligned on the axis of the disk) isn't going to be very steerable, especially if the distances from the EDGES of the disk to the sensor all have to match within a half-wavelength in order for the interferometry to work right.

And wouldn't the changing relative positions of earth, moon, and sun cause disturbances in the disk? Is the solar wind sufficiently uniform over distances of 1/2 mile at earth orbit to not be a concern for causing non-uniform disturbances to the disk?

"geostationary" MUST be a mistake in the article. I don't see how the sensor can maintain a 1/2 wavelength position from the disk at a range of 10 to 100 miles unless the sensor is powered (ion drive?) somehow.

Is the entire car 3D printed?

Everything on the car that could be integrated into a single material piece has been printed. This includes the chassis/frame, exterior body, and some interior features. The mechanical components of the vehicle, like battery, motors, wiring, and suspension, are sourced from Renault’s Twizy, an electric powered city car.

Disney does have some control over it's employees. Just as it can fire employees for coming to work drunk - or for risking the lives of fellow employees or visitors, so it can take measures that affect their employment in regards to vaccinations and disease outbreaks, from banning un-vaccinated employees access to public spaces to limiting their leaves to making vaccination a condition of employment. (Of course, that doesn't solve the problem of employment practices that penalize people for taking sick-time, etc.) But that's not going to solve Disney's problem because it currently can't discriminate against visitors who aren't vaccinated and so the impression of large theme parks as being a Horrifying Den of Disease is going to persist.

Disney isn't going to want to alienate it's customers by running advertisements asking people who aren't vaccinated to avoid coming to it's parks. It'll just irritate the anti-vaccination crowd and scare off the conventional people who think the anti-vaccination crown is terribly, horribly wrong (and irresponsible enough to visit anyway.)

A trade association COULD run public service messages to the effect that willfully avoiding vaccination is as bad as drunk driving and killing a family in a car accident. The government COULD make vaccination records available on state issued ID cards (drivers licenses, etc.)

This is a public health and safety issue, and like most such issues, practical and efficient solutions can come into conflict with some perceived individual freedoms. Even worse for some people, it involves the dreaded word "compromise". For instance, I give up the freedom to drive a car where ever I want to so that I have some assurance that I'm safe from people driving the opposite direction on the same side of the road I'm on, or on my lawn.

Perhaps the right solution (compromise) would be standardized, opt-in credentials that indicate what kind of conventional (sensible) things I'm willing to abide by, like:

• (*) I'm vaccinated;
• (*) I'm NOT packing a firearm;
• (*) I don't chew gum in public.

People who think that such assertions are an infringement of their privacy don't need to opt-in. Privately run facilities could make decisions based on those credentials - although Public parks would probably not be able to.

While this is purely speculation, could China be aiming to offer itself as a global (or even regional) interconnect? Or is the the ability to play NSA-like games on international traffic within home-borders just not a realistic possibility anymore?

I'm thinking of how a "Chinese" error (in Germany) caused traffic between two Russian cities to be directed out-of-country (see http://research.dyn.com/2014/1... ).

I can take the tin-foil hat off anytime I want to, but I really do like the propeller beanie.

Ignore (for now) the possibilities of vendor-abandoned embedded software on your home network to cause mischief or frustration.

Ignore (for now) someone spear-phishing you with your fridge or washing machine.

Just think about all of the lovely data collected into one central place about a home address where people with lots of disposable income live.

The flaw we're seeing here is various "computer security journalists" (and journals) destroying their reputations.

This is on the order of discovering that big heavy things that fall on your foot can cause pain.

Definitely a weird article. If you ignore the hyperbole, all you get is a military boondoggle. The idea that it's part of some NSA spying operation falls apart in the face of the Raytheon promotional material - "double digits of swarming boats" and "hundreds of cars" in the Baltimore area sounds woefully insufficient, either for tracking suspected cruise missile delivery systems or giving the NSA anything more useful than what they have.
I suppose it might be practical for protecting Marquette, MI from an invasion from Canada.

Given how overweight most Americans are, I suspect that any effects of nude flying on TSA worker morale will be negative.

If the tolls were used to offset another public good (public schools being the only other one that's nearly as expensive), it might work to encourage either people living in-town, or some businesses leaving town. Of course, that would only work if schools and the toll roads were under the same authority. (FYI, I live in Ann Arbor, Michigan where while we might complain about traffic and parking, we don't have anything like LA's situation. But being part of Michigan, we probably have the worst roads in the nation and a GOP/Tea Party dominated state government that's so tax-phobic that it's even more dysfunctional than the US House of Representatives.)

On a Ubuntu 14.04 install, Chrome's most unique component was WebGL. On a Macbook Pro (Mavericks), it was the list of plugins, followed by the font list. For both, the Canvas was shared with less than 1%

Curiously, Do Not Track is reported as "yes" for Ubuntu, but "1" for Safari.

Union? That's a four-letter word around here - with an off-by-one error.

The video shows some kind of wide laser projector about a centimeter or so above a test-rig, with sparks flaring off, and the rail moving at a (relatively) slow rate - perhaps one or two Kph.

If the sparks were only burnt excess "leaf material", that isn't a problem - but if it's rust or steel fragments burning up, that's material coming off of the rails - in effect, wear.

If this is intended to be used continuously while the train is in motion in order to keep the rails clear of debris, how much energy can be delivered to a leaf from a fixed projector moving at 50Kph? If this does deliver enough power to cause the leave to disappear in a puff-of-smoke, isn't there a chance of heating the surface of the rail enough for the carbon ashes pressed into the rail by the subsequent advance of the train to chemically react with the rail?

This might be ok for single layers of leaves - but how long does it take for multiple layers of leaves to build up on a rail?

If the huge amount of leaves in the video is characteristic of the problem they want to solve, won't the wind from the passage of any train moving at speed just redistribute more leaves on the rails behind it?

I predate MIMO, so I had to take a brief refresher in what it is - and if I understand correctly what I read of MIMO (and what I read was correct - two important provisos!), MIMO seems to depend on using digital signal processing to be able to match the emit and receive channels, but it is using a physical separation (on the WiFi access-point side) of a few centimeters between antenna. I can see where you might find that kind of separation in laptops or even tablets, but not necessarily in a cell phone or an Internet-of-Things tiny appliance (like a light-bulb.) I couldn't tell how stateful the DSP part would have to be, or how long it would take to optimize for a particular set of signal paths. I also couldn't tell how well MIMO works out in a mix of MIMO clients and non-MIMO clients (like my IoT light-bulb). Can anyone offer any guidance?

QAM strikes me as (somewhat) incompatible with MIMO because using phase-shifted channels (QAM) (carrying different data) would be akin to space-shifted channels (MIMO) when the wavelengths and the distance between the antenna are similar - and the distance (and phase) between the MIMO antenna depend on the orientation between the sender and receiver of MIMO. But maybe that's just more DSPing?
