+ - The Quantum Experiment That Simulates A Time Machine

Submitted by KentuckyFC
KentuckyFC (1144503) writes "One of the extraordinary features of quantum mechanics is that one quantum system can simulate the behaviour of another that might otherwise be difficult to create. That's exactly what a group of physicists in Australia have done in creating a quantum system that simulates a quantum time machine. Back in the early 90s, physicists showed that a quantum particle could enter a region of spacetime that loops back on itself, known as a closed timelike curve, without creating grandfather-type paradoxes in which time travellers kill their grandfathers thereby ensuring they could never have existed to travel back in time in the first place. Nobody has ever built a quantum closed time-like curve but now they don't have to. The Australian team have simulated its behaviour by allowing two entangled photons to interfere with each other in a way that recreates the behaviour of a single photon interacting with an older version of itself. The results are in perfect agreement with predictions from the 1990s--there are no grandfather-type paradoxes. Interestingly, the results are entirely compatible with relativity, suggesting that this type of experiment might be an interesting way of reconciling it with quantum mechanics."

+ - Where are the Linux talents?->

Submitted by Taco Cowboy
Taco Cowboy (5327) writes "IT is changing organizations across the globe, impacting enterprises, governments and the wider public sector. Open source in particular is a driver in innovation, giving organizations a competitive edge and an ability to scale and adapt to changing market demands.

According to the 2014 Linux Jobs Report, demand for Linux expertise continues to grow, with hiring managers across a number of industries citing Linux talents as one of the top recruitment priorities this year

Unsurprisingly, with more government IT transformation projects under way in Asia Pacific, the need to reinvest in government employees' skills is also on the rise. This may be due to legacy systems, often built on proprietary platforms and supported by IT teams with skill sets limited by the technologies they had to maintain

An example of the legacy system is Lotus Notes system, which was adopted by governments throughout southeast Asia over the past 20 years. When the time came for these governments to move to a new and more capable platform, they had to conduct extensive staff retraining for a new tool. Of course, this led to climbing expenditures given the need for new training

With proprietary systems like Lotus Notes, there is a need to keep learning fixed and limited skills to support proprietary, vendor-specific set ups. Open source knowledge (Linux training) is, generally, highly transferable and can be applied to almost any Linux platform

Hiring managers in both governments and enterprises are bolstering Linux talent plans, according to the 2014 Linux Jobs Report. This report is assembled from a survey taken across 1,100 hiring managers and 4,000 professionals within the Linux space

In fact, the demand for Linux expertise is so high that salaries are being driven above industry norms, in turn causing these Linux professionals to identify Linux knowledge as a career-advancing tool

In Singapore, the Singaporean government appears to understand the need for local initiatives and frameworks, as the new fair consideration framework has led to increased competition for local IT talent

"Due to a limited talent pool in the storage, security, cloud or hosted domains, the market is also facing a shortage of technically skilled pre-sales people," said Regional Director of Hays in Singapore and Malaysia, Chris Mead. He explained that service management, cloud architecture and process and quality specialist roles were also in high demand

"We expect the supply shortage of these professionals to continue as businesses are consistently evaluating their IT operations to enable optimal efficiency and a continual improvement of their IT services"

It is thus important that IT professionals find the appropriate training that will prove to be a long term asset to them and their organizations. On the other side of this transformation governments should consider local initiatives to support Linux training programs, thus growing the skill base for Linux and other open source standards."

What I'm saying is that calling people "sheeples" is inherently anti-democratic

So what do you call them?

By any other name the sheeples are still acting like sheeps

They do not like to think, they do not like to think so much that they let others to do all the thinking for themselves

And when that happens, someone else do come out and does the thinking for them ... that someone is nothing but the authority

So the authority tells the sheeples that what they are doing --- that BLANKET SNOOPING THING is "good for them" because it will "protect them from the baddies", you know, them "terrorists", them "pedophiles", them with "bad intentions"

And the sheeples bought that shit wholesale --- with line and hook and barrel and everything in between

You want your democracy, so be it, but do not tell me that calling a spade a spade is undemocratic

We can call the "Sheeples" a "Rose", or a "Tulip", or even "Alfalfa", but that name change ain't gonna change their character, not even a bit, Sir !

Sir,

I do agree with you that we do need hope, but we must *NOT* forget the fact that 'hoping' ain't gonna do us, or anybody else, any good, especially when what is happening now, from top down (well, the governments are *ON THE TOP* of the people, no matter which government, no matter which nation)

Nowadays governments treat their citizens with contemp

They suspect their citizens so much that they actually take steps to ensure that every single thing their own citizen does must be checked, categorized, and actions must be taken on whoever they suspect (for whatever reason)

Hope in itself is no longer sufficient to fight those fascist, my friend

We no longer live in the 1960's, Sir

We no longer live in a world where the government listens to the people

No man. We are living in the world where the governments DEMAND to be respected, or else

That's the reality all of us are living in, no matter if you live in Canada or China or Saudi Arabia or America or Great Britain, it's all the same --- you, a citizen, better be a sheeple, or we will mark you, we will follow you, we will watch your every single move

Dear Sir,

I may have been thinking too much. In fact, you may even say that I am paranoid - but at the stage that we are in today, that the blanket snooping activities into almost everything that we do online and off, we do need to question why the authority's need to do it, rather than accept what they are telling us by default

Yes, they tell us they are 'looking for terrorists' but is that true?

I mean, if they are 'looking for terrorists' the obvious target for those 'terrorists' are those from a particular religion (that peaceful one, to boot)

But is the authority looking into that group only?

Far from that. They are snooping in on ALL OF US, on our email, on our surfing pattern, on the site we go to, on what we download, on our phone conversation, on everything everybody is doing

Then why are they doing it?

Surely the 'looking for terrorists' excuse ain't gonna cut it no more, there gotta be more than what they are telling us

Yes, I am paranoid, I admit it. But you can't blame me from being paranoid

I am from China, a country which is being ruled by some really despicable regime. At the point when I left China the entire society was in turmoil. People were being pulled out on to the street and beaten, sometimes killed, just because they were labeled as 'anti-revolutionary'

I have had that kind of experiences. Most of you do not. I know what the authority is capable of doing, and what they will do to maintain their control over us, the peons

The more I look at what's happening in the so-called "Western countries" the more it resembles that despicable regime that is controlling China

Yes, I am have been 'overthinking', as you put it, but I rather be paranoid and right and be well prepared (as well as knowing what preventive actions to take before the shit hits the fan), than be totally unprepared and suffered the consequences

But it's all up to you guys. What I am telling you is what I, and many millions of older generation of Chinese had gone through --- we do not trust the authority, we do not trust anyone but ourselves

If you guys insist that the authority is to be trusted, that they are doing what they are doing for 'the good of the people', then that's your right to do what ever you want to do

But when the shit hits the fan (which I fervently hope it will never come true) don't blame me for not forewarning you guys

It happened in China, it could happen, and I repeat, it could happen elsewhere, including the Western countries

You said:

... as terrorists. I have accepted that. Just change the laws to reflect reality now so we don't have this silly mismatch ...

Actually their target is further than that
 
To illustrate what I mean, let's look at what TFA says ...

... Canada's electronic spy agency sifts through millions of videos and documents downloaded online every day by people around the world, as part of a sweeping bid to find extremist plots and suspects ...

Are they truly looking for "extremist plots and suspects"?

No

Then what they are looking for?

They are looking for potential targets that they deem "dangerous". No, not terrorists but those amongst the people who are NOT sheeples!

You see, those fascists (to put them in a milder term will be an injustice, they are fascists afterall) are not afraid of sheeples. In fact, they WANT all the people to become sheeples so that they can get absolute control over them

What the fascists are afraid, very afraid of, is those amongst us who steadfastly REFUSE to become a sheeple, who instead will use our own brain to think, rather than delegate the thinking to "somebody else", ie, the authority

That is what makes those fucking fascists antsy --- they can't have that, but current laws still do not allow them to pull out all the non-sheeples to the street and shoot them

So they do the next best ... to identify the non-sheeples so that, when it comes the day they can pull people out to the street and carry out summary execution, they would know who to shoot

That is ultimately WHAT they are doing today ... identifying us, closely monitoring us, categorizing us, ... and ultimately, know who they need to eliminate, and where to get those 'trouble makers'

+ - The iPad Is 5 Years Old This Week But You Still Don't Need One

Submitted by HughPickens.com
HughPickens.com (3830033) writes "Will Oremus writes at Future Tense that five years ago Steve Jobs introduced the iPad and insisted that it would do several things better than either a laptop or a smartphone: browse the web, send email, watch videos, enjoy your music collection, play games, read ebooks. By most standards, the iPad has been a success, and the tablet has indeed emerged as a third category of computing device but there's another way of looking at the iPad. According to Oremus, Jobs was right to leave out the productivity features and go big on the simple tactile pleasure of holding the Internet in your hands. But for all its popularity and appeal, the iPad never has quite cleared the bar Jobs set for it, which was to be “far better” at some key tasks than a laptop or a smartphone. The iPad may have been "far better" when it was first released but smartphones have come a long way. The iPhone 6 and 6 Plus and their Android equivalents are now convenient enough for most mobile computing tasks that there’s no need to carry around a tablet as well. That helps explain why iPad sales have plateaued, rather than continuing to ascend to the stratospheric levels of the iPhone. "The iPad remains an impressive machine. But it also remains a luxury item rather than a necessity," concludes Oremus. "Again, by most standards, it is a major success. Just not by the high standards that Jobs himself set for it five years ago.""

The impact of the flaw is troubling because BlackPhone attracts what hackers see as high-value victims: those willing to invest AU$765 (£415, $630) in a phone that claims to put security above form and features may well have valuable calls and texts to hide from eavesdroppers."

Submitted by ldickens
ldickens (3995491) writes "I hope you can help us, and we’re willing to pay a bounty for a silver bullet. This isn’t the first time Nomadix and Acacia have tried to sue hotspot operators for captive portal patents they hold from the late 1999’s. Scanning old articles from this forum, and others, we learned that in 2004 Acacia launched a broad-based assault on hotspot providers to hotels and coffee shops for redirecting to a captive portal. Nomadix (owned by NTT Docomo) also began suing companies in 2005 using different patents directress to the same basic concept. Many within the SlashDot community responded then, some posting righteous outrage, noting knowledge of prior use of this very technology. Now, in 2015, Nomadix is at it again, suing my company, Blueprint RF – a hotel hotspot provider.

So we’re now asking this community to support our defense by providing any information you may have to lend. We need clear published references or documented prior use dating back at least to 1998 and preferably 1997 or earlier showing automatic browser redirection to a login server. We’ll give $1,500 to anyone who produces evidence, that we are not already aware of, that helps us invalidate any of the patents at issue. Please send your questions or submittals to me at priorart@blueprintrf.com

The technology in question is TCP transparent proxy, 'ipfw fwd 127.0.0.1' in FreeBSD, combined with an HTTP 303 redirect message in order to send them to a page that they did not initially request. In our case, this is typically the login page you encounter at hotels. Here are links to the patents in question:

Please understand that we respect the patent system and legitimate innovation. But we do not want to be held to pay for using technology that was in use before the patents at issue, which we believe to be the case here. Thank you so much for considering our plight and any information that you can provide."
