this is surprisingly true. I have been a alpha tester. It is quite easy to set off. just 4 press of power button. Something that can happen very easy e.g.

if you want to check time (press power),

turn screen off (press power),

"wait what time is it" (press power)

"oh yeah" turn off screen (press power).

bzzzzzzzzzzzzz

"fuuuu".

The problem exists on AMD CPUs, not Intels.

[...] for Intel Core Solo
and Intel Core Duo processors [...]: the time-stamp counter increments at a constant rate. The specific processor configuration determines the behavior. Constant TSC behavior ensures that the duration
of each clock tick is uniform and supports the use of the TSC as a wall clock timer even if the processor core
changes frequency. This is the architectural behavior moving forward.

why not just add three microphones to your table and use a dump stick as your pencil. the sound waves are delayed proportional to the distance. by correlating the three signals you are able to get the distance between pencil and microphone. knowing the position of your three microphones you are able to calculate the position of the pencil.

i think there was a demo with piezo microphones on a wall or chipboard, but i'm not able to find it.
No, I've never heard of anyone having a dashcam in the Netherlands. I've also never heard of (liability) insurance companies not paying out. Jumping in front of a car in order to sue for damages is pointless here, since you cannot sue for emotional damages. Since insurance pays for physical damage only, there's simply no point in trying to commit fraud in that way.

Not very Von Neumann was a genius in every single form of the word. The only historical figures I feel safe comparing him to is Sir Isaac Newton (which is a stretch Newton is really beyond compare).

Von Neumann also got the priviledge later in his life to work with Einstien and Kurt Gödel while in New Jersey.

The joke about infinite sums is one of Von Neumann's associates asked him

>"Two trains are 20 miles apart on the same track heading towards each other at 10 miles per hour, on a collision course. At the same time, a bee takes off from the nose of one train at 20 miles per hour, towards the other train. As soon as the bee reaches the other train, it bangs huwey and heads off at 20 miles per hour back towards the first train. It continues to do this until the trains collide, killing the bee.

>How far will the bee have traveled?"

This is called a mathematicians trap. And its similiar to XKCD 356 (Nerd Snipping) [2]. There is a simple eloquent algebraic way to solve the problem, but it requires some insite. And there is a complex way involving summing an infinite series. Normally mathematicians end up preforming a very vast complex infinite series sum. [1]

When Von Neumann was asked the question it took him about 10 seconds to respond.

The associate who asked him stated, "Oh you must have heard the joke before."

To which Von Neumann responded, "No I just solved for the sum of the infinite series."

They don't have revenue targets. Quora is a zero revenue operation, they don't have a business model.

Quora just raised money at a billion dollar valuation basically. By comparison, Answers.com, a much larger site by traffic (with a $7+ cpm rate), was purchased for a mere $127 million, and was struggling to punch above $20 million in annual revenue.

Then you have to ask: what about Quora being worth $3+ billion, so their investors can get a return? There's no scenario that will ever get them there in the Q&A space (it'd require ~$300 million in revenue, literally impossible for them to pull off as is). They have to pivot out of Q&A because they can never justify their valuation, and they know it. To be worth that much they need to be a top 50 site in terms of traffic, and they're nowhere near that.

Wikia for example is substantially larger than Quora, and they couldn't even get close to justifying a multi-billion dollar valuation via advertising. Or consider Angie's List, worth $700 million, but tracking toward $300 million in revenue. Quora's investors have a huge problem ahead of them.

That then tells you the areas of focus in terms of the problem to correct.

I don't get it - would you prefer that Australia doesn't report on the Egyptian government suppressing free speech?

As to why this story rises to the top in the international press, it's because it's a bit meta - when you have free press in your country, other countries can leave the reporting of internal affairs to the local media. The loss of this internal check and balance is an important event on an international scale, whereas, quite frankly, the sentencing of death to Egyptians by their courts isn't.

The importance of the Flight challenge is debatable, I suppose but it is defined well. That's important.

"If Flight wins the vote, the challenge for Longitude Prize 2014 will be set to design and build a zero or close-to-zero-carbon aeroplane that is capable of flying from London to Edinburgh, at comparable speed to today’s aircraft."

If you don't think its environmentally valuable, at least it's valuable as an engineering challenge.

The definition of the Food challenge is much poorer:

"If Food wins the vote, the challenge for Longitude Prize 2014 will be set to invent the next big food innovation, helping ensure a future where everyone has enough nutritious, affordable and environmentally sustainable food that people want to eat. A successful solution will demonstrate benefit at a small scale now and show projections of the potential environmental and social impact of scaling up to provide for millions of people."

If no one had seen a potato before, growing a field of them could presumably win this challenge. It would be easy to demonstrate on a small scale and make the case for scaling up. The whole problem is scaling up with all the political & economic hair that goes with it. We're pretty good at cheap calories.

I disagree about Water:

"creating a cheap, environmentally sustainable desalination technology."

Clearly defined and would have many high value implementations including many humanitarian ones. The only knock on it is that I think there is sufficient economic incentive that a £10m prize won't make much difference. I could be wrong though.

"You might as well hire on color of their eyes."

Egyptians putting Egyptians on trial has almost nothing to do with the rest of the world. It's Egyptians doing it to themselves, and really isn't our concern anymore than it is your concern for how we sentence drug crime here. Besides, An African or Middle Eastern country doing something stupid is so common place, it's simply not news anymore.

Regardless, it would be bigger news if a western country jailed an Egyptian for telling false news. Reporters are still sacred for a while longer in the west, and to imprison a reporter goes beyond a chilling effect.
My dad used a bike seat for me, which was doable since my brother and I were different ages and weren't often going to the same place. There are of course bike trailers for hauling 2-3 children around and don't forget pedicabs which regularly haul around 3-4 adults.

After you get used to it you don't really feel exhausted. Yes commuting 20 miles by bike is definitely an upper limit, at least for me, but I do know people with longer bike commutes.

So assuming you fuel yourself with pure beef, the most unsustainable food I could find, you'd need about .85 kg to get 2000 calories. On average the production of beef releases about 13.3 kg of CO2 per kg of beef, so we're looking at 11.305 kg of CO2 per commute. The average CO2 produced for a medium sized car is about .5 kg per mile. So for the same 40 mile commute you're looking at around 20 kg of emissions. So even if you choose to only eat the most unsustainable food it's still better than driving. If you switch to pork or poultry you can reduce that 11.305 kg of CO2 by about 75%. Cars just don't even come close.
This kind of thing goes on all the time, all over the world, to varying degrees. It's definitely something I'd read about in The Economist, but it's not at all "intellectually gratifying", and is off topic as a political current event for this site.

That's funny. I wouldn't hire my friends for exactly the same reason.
There is a bit of history and context needed here I think. The last Opera 12 was released about a year ago. Last year they announced they would switch to using Blink instead of their own rendering engine.

The engine switch came with a complete rewrite of their browser as far as I understand it, so they prioritized Windows/OSX stability for a year and now finally came up with a Linux build again. The big gap in version numbers is due to their new browser starting at 15 + the adoption of a much shorter release cycle.

Once Linux builds are made stable I expect they will continue to release builds on all 3 platforms as they were doing for the many years before this slightly extreme shift.
New level of stalking: Skype keeps recording me after finishing the call

I did the same thing it twice with the same results. I quit the Skype and don't know what to do :( Everything worked fine in previous versions. Does anybody have the same behavior?

I too have never understood how the scroll wheel could be considered intuitive. The first time I saw one I was somewhat baffled until my friend showed it to me and even then it was always a struggle to control.

The death of journalists during intense fighting is - while extremely tragic and hopefully rare - not at all comparable to them getting sentenced by courts for simply reporting news. The former is to some degree unavoidable (if they got target specifically then everything changes), while the latter is an explicit act of government against freedom of press and speech.
"The point of the article and its title "mirrortocracy" is that these people are building clones of themselves because of their narrowmindedness and that's increasing their chances of failure."

I know that is what they claim, but is there any proof? Anything at all? That was my question. The claim is that you should hire people you know nothing about rather than people you know something about. Like if you are from Harvard, you shouldn't hire other people from Harvard, you should hire people from some community college, who are as different from you as possible.

"This is no different than any narrowminded and now dead organisation of the past that failed to survive because they couldn't take on people who weren't "the right type". "

Which organizations you talking about? Name at least one example, please. I am not aware of such a story.

Another way to phrase the question: should you hire people you could likely be friends with? If not, why not?

> All in all, this war is moot. Moore's law applied to bandwith, to device computation speed and to software evolution leads to this: http://xkcd.com/1367/

Not really.

If you have massively powerful devices and massively fast connections then you move to a situation where you've still got to address differences between the programming models and and the feature sets on the various devices.

For a web app to have parity with a native app there are still significant technology gaps which need to be closed - offline working (moving in the right direction, still not great), native look, feel and functionality (difficult if you want it to run on multiple device types) and so on. Some of those will close over time, some may not.

But harder to close off - I struggle to see how cross platform will every be much more than lowest common denominator given the consensus required on how to adopt new features as they arrive on phones. Apple launches TouchID, Samsung launch fingerprint scanning. How long before the W3C define a standard for that and the companies adopt it? How much time is that where native developers are at an advantage?

The web is great and web apps will definitely be a bigger part of things going forward, but I think it's simplistic to assume that they'll take over.

As for a present day Microsoft, I don't see that happening. Back then interoperability was a nightmare - if the person I wanted to work with wasn't running the same OS as me I was basically screwed. Right now I can collaborate with someone and generally speaking I don't care what they're running and it really doesn't matter.
It's not impossible, is it? Companies fire people they had employed for years all the time. Friends drift apart all over the world, all the time, too.
