The analysis paper starts out by saying "With hundreds of millions of devices expected to be traded by 2018, flaws...could be a serious problem." Unfortunately that same analysis focused on Android operating systems PRIOR to v4.4 (KitKat), which was released in October 2013 (https://en.wikipedia.org/wiki/Android_version_history).

Since then, Android has released major versions (4.4 Kitkat, 5.0 Lollipop) and various major updates within those families (4.4.2, 4.4.4, 5.1). To put this in perspective, they're talking about risks in 2018 from software no newer than 2013 while writing and publishing in 2015. That's a classic case of picking your data to fit your conclusion, or cherry picking (https://en.wikipedia.org/wiki/Cherry_picking_%28fallacy%29).

There were many fixes in Android security systems in 4.4 and also in 5.0. 5.0 now supports hardware encryption on e.g. HTC and OnePlusOne platforms among others. To apply "anyone can get the key and brute-force a password"[paraphrased] is to deny that no, you can't.

It's often more convenient for "researchers" to provide something with glitz and hype to catch the media's attention, but in this case the hype cherry-picks data that ignores two years of active open-source development and many security updates.

Poor science and hyperbolic headlines make for brain-free reading.

The taxi lobby and the insurance lobby are organizations that stand to benefit from this law each in their own way.

The taxi lobby doesn't have to contend with competition from Uber drivers [regardless of your quip about taxi service].
The insurance lobby doesn't have to contend with Uber drivers' increased risk from above-average mileage without additional insurance premiums.

It's a win/win for the existing industries and a lose/lose for Uber drivers and Uber passengers.

1. He has no obligation to "come free and clear". That's just something you made up, and something LEOs wish, but not a requirement under US law.
2. If he was "personally threatening" then he would have made a threat.

I'm sure it will come out that this guy WAS pranking... seeing as he offered no specifics to make either a *usable* warning or a *credible* threat.

That doesn't change everyone bending over to pretend this is a crime; that we can't say "bomb" in an airport; and that we must be otherwise conditioned not to say "4/16" in Virginia. (or "9/11" anywhere even though that's what you dial in an emergency and we have to tell the children that's what to dial. Think of the children.)

I can't imagine how horrible it must be for people who's birthday is April 16th and who live in Virginia to ever discuss their upcoming party. "4/16 is going to be a blast!"

I've read the previous posters' comments, and I understand all about the freedom of speech, the misunderstood Oliver Wendell Holmes quote about "fire in a crowded theater", and that "speech by computer" shouldn't equal a crime (right, it shouldn't).

HOWEVER, in all these great discussions it seems everyone is accepting and begging the question that the original comment about there being a repetition of XX/YY is a THREAT.

Sorry guys and gals, that's an anonymous TIP, a WARNING, a PREDICTION, the kind of thing that kindly old lady on the 900 number tells you, something your mother says if you touch a hot stove, etc. Call it what you will, but it's not a threat.

A threat requires an INTENTION to INFLICT or CAUSE HARM. It may even suggest that the person making the threat will be the one doing it. Google threat or here's an easy definition: http://www.thefreedictionary.c...

Fundamentally this guy said something on the Internet. He has now been excoriated as "an idiot" "said stupid things" "ha ha he'll get ***ed in the holding cell" "serves him right for making a threat."

It's only a matter of time before the LEOs say "You can't say those things and live."

Yes. In the United States we can.

I'm disappointed /. readers decided to punish the victim and accept the TSA-airport-attitude that "if you say bomb then we'll arrest you right then and there" and then when a passenger does say "bomb" we call him a stupid idiot. Stupid is the idiot that accepts this as his way of life and defends this insane idea that somehow making speech unlawful is either Constitutionally ok, or even helps our security [theater] at all.

Cheers guys and gals,

Comment: No end-user would do this fiscally (Score 1) 226

Pretend you wanted to drive 8000 miles. The IRS expects that the cost per mile allowance is $0.50 based on gas, oil, tires, vehicle depreciation.

To drive those 8000 miles the apportioned cost would be $4,000. You can get 10 round-trip tickets London-NY off-season and 5 on-season for that.

During your trip if you follow your manufacturer's recommendations you'd need to change your oil three times. So would everyone else. At equal intervals. What a pile up at the mechanic at 3000m, 6000m, and just past it. Yuck!

If you have average street tires then the trip there and back would kill half your tires (so they only have half left on them you need to replace them on this trip).

If the speed limit was set at 100MPH and there were no stops you'd actually maintain that, but given that you will stop to stretch your legs, etc. that average goes down to about 80. That's 100 hours of driving, which with two drivers and sleeping in the car is 5 solid days. What's the value of 10-man-days lost?

Finally even if all those things were true, the largest cargo that could be transported is a triple-tractor trailer -- 3 containers. This ship can do 18,400 http://en.wikipedia.org/wiki/M.... You'd need 6,133 trucks to equal that and it would take them 5 days. The cargo ship can make it in 3-4.

This is a nonstarter from every possible fiscal angle for the end-users, even if the road magically arrived today.*

Comment: Article is wrong. Transceivers do this already. (Score 4, Interesting) 47

The article is misleading. Transmission and reception on the same "frequency" is done today. However, there's some other "discriminator" in the signal. Either modulation method, phase, shift, orientation, or "something" is different so that the receive and transmit don't collide.

This article -- despite its misleading introduction -- talks about a limited application whereby RX and TX can occur using the same frequency *BAND* (they say "spread spectrum") and allow full-duplex communication. The advance is that this is all on one chip.

What would be truly revolutionary, like the example of two people talking to each other at the same time, is the ability to transmit and receive using the *same* exact method by both transceivers. THAT would be the holy grail.

Not there yet.

It depends what you mean by "by design" is :)

Air is a great insulator, but poor conductor of heat.

My familiarity is with generatios of Dell laptops that exchange more heat through the bottom of the case they do they through venting to the air. Their support system even ensures you tell them if you're using your laptop "on a solid hard surface".

FYI 100C is higher than most hardware's failure point.

In a laptop, the use of similar devices makes sense, as the heat can be transferred
somewhere where it can be dissipated into the air. Unfortunately it's more efficient
to transfer it to the table you have it on, so the bottom gets the heatsink which
makes it horrible to actually put your laptop on your lap-top.

In a smartphone, it's being held in your hand (on the back) and up to your face (on
the front) with fingers on the sides. Where to exactly are they going to move the
heat??? Heat exchanging is nothing new, but the ability to remove heat requires
the device interact with a cooler medium to transfer that heat. Normally that's
your palm, or the air, or both.

So... I ask again... transfer the heat to where?
