Submission + - Is the Higgs Boson a Piece of the Matter-Antimatter Puzzle? (stanford.edu)

TaleSlinger writes: Why there's more matter than antimatter is one of the biggest questions confounding particle physicists and cosmologists, and it cuts to the heart of our own existence. In the time following the Big Bang, when the budding universe cooled enough for matter to form, most matter-antimatter particle pairs that popped into existence annihilated each other. Yet something tipped the balance in favor of matter, or we – and stars, planets, galaxies, life – would not be here.

The paper is based on a phenomenon called CP – or charge-parity – violation, the same phenomenon investigated by BaBar. CP violation means that nature treats a particle and its oppositely charged mirror-image version differently.

"Searching for CP violation at the LHC is tricky," Dolan said. "We've just started to look into the properties of the Higgs, and the experiments must be very carefully designed if we are to improve our understanding of how the Higgs behaves under different conditions.”

The theorists proposed that experimenters look for a process in which a Higgs decays into two tau particles, which are like supersized cousins of electrons, while the remainder of the energy from the original proton-proton collision sprays outward in two jets. Any mix of CP-even and CP-odd in the Higgs is revealed by the angle between the two jets.

"I wanted to add a CP violation measurement to our analysis, and what Matt, Martin and Michael proposed is the most viable avenue,” Philip Harris, a staff physicist at CERN and co-author of the paper said, adding that he's looking forward to all the data the LHC will generate when it starts up again early next year at its full design strength.

"Even with just a few months of data we can start to make real statements about the Higgs and CP violation," he said.

Submission + - Ask Slashdot: What can I really do with a Smart Watch? 1

kwelch007 writes: I commonly work in a clean-room (CR.) As such, I commonly need access to my smart-phone for various reasons while inside the CR...but, I commonly keep it in my front pocket INSIDE my clean-suit. Therefore, to get my phone out of my pocket, I have to leave the room, get my phone out of my pocket, and because I have a one track mind, commonly leave it sitting on a table or something in the CR, so I then have to either have someone bring it to me, or suit back up and go get it myself...a real pain. I have been looking in to getting a "Smart Watch" (I'm preferential to Android, but I know Apple has similar smart-watches.) I would use a smart-watch as a convenient, easy to transport and access method to access basic communications (email alerts, text, weather maps, etc.) The problem I'm finding while researching these devices is, I'm not finding many apps. Sure, they can look like a nice digital watch, but I can spend $10 for that...not the several hundred or whatever to buy a smart-watch. What are some apps I can get? (don't care about platform, don't care if they're free) I just want to know what's the best out there, and what it can do? I couldn't care less about it being a watch...we have these things called clocks all over the place. I need various sorts of data access. I don't care if it has to pair with my smart-phone using Bluetooth or whatever, and it won't have to be a 100% solution...it would be more of a convenience that is worth the several hundred dollars to me. My phone will never be more than 5 feet away, it's just inconvenient to physically access it. Further, I am also a developer...what is the best platform to develop for these wearable devices on, and why? Maybe I could make my own apps? Is it worth waiting for the next generation of smart-watches?

A Domain Registrar Is Starting a Fiber ISP To Compete With Comcast 65

Jason Koebler writes: Tucows Inc., an internet company that's been around since the early 90s — it's generally known for being in the shareware business and for registering and selling premium domain names — announced that it's becoming an internet service provider. Tucows will offer fiber internet to customers in Charlottesville, Virginia — which is served by Comcast and CenturyLink — in early 2015 and eventually wants to expand to other markets all over the country. "Everyone who has built a well-run gigabit network has had demand exceeding their expectations," Elliot Noss, Tucows' CEO said. "We think there's space in the market for businesses like us and smaller."

True, a degree doesn't mean they have those traits. But this is where conditional probability comes into play. More people with the degree will fall into this category than those without, because the degree gives them the knowledge to wield those traits effectively. That means that when looking at a resume, you're more likely to get a good hire from one with a degree than without. And several of those traits are positively associated with a degree. Additionally, the floor is higher- while even those with a degree can be a bad hire, a mistake is more likely to be a mediocre worker than a bad one. So you minimize your risks and maximize your potential gains by just dropping the other pile, looking for diamonds in the rough isn't worth the time and money. Especially since the type of person you're discussing won't be easily discernible from a resume, you're looking at phone or in person interviews at much higher cost/effort to have a chance.

One exception I would make is with a personal testimonial of the non-degreed dev's skill by a developer I trust. But you're looking at corner cases there.

Verizon "End-to-End" Encrypted Calling Includes Law Enforcement Backdoor 170

An anonymous reader sends this quote from TechDirt: As a string of whistle blowers like former AT&T employee Mark Klein have made clear abundantly clear, the line purportedly separating intelligence operations from the nation's incumbent phone companies was all-but obliterated long ago. As such, it's relatively amusing to see Verizon announce this week that the company is offering up a new encrypted wireless voice service named Voice Cypher. Voice Cypher, Verizon states, offers "end-to-end" encryption for voice calls on iOS, Android, or BlackBerry devices equipped with a special app made by Cellcrypt.

Verizon says it's initially pitching the $45 per phone service to government agencies and corporations, but would ultimately love to offer it to consumers as a line item on your bill. Of course by "end-to-end encryption," Verizon means that the new $45 per phone service includes an embedded NSA backdoor free of charge. Apparently, in Verizon-land, "end-to-end encryption" means something entirely different than it does in the real world.

No, it absolutely won't. First off- drop the idiotic lingo. All it does is make you look like a tool. Secondly- the "rockstar" tends to have a degree. That's part of why he's so good, he's studied the foundation of his craft and understand the costs and benefits of different approaches. Once again, someone with a degree is far more likely to be able to do that then one without.

Secondly, when looking for high impact workers- the things you want don't correlate to no degree. What you want is hard working, creative, a willingness to step up and take ownership, and high intelligence. Lacking a degree means he's not likely to be hard working, he wasn't willing to put in the work to go to college. It means he wasn't willing to take ownership of his own career path. And it means he was either too stupid to get into college, or too stupid to see the benefits of it. The only one you might get is creative because he "went a different way"- but he did so without thought or a good reason for doing so, which again isn't what you want.

So yeah, the non-degree holder loses again. THere's a few exceptions (although only 1 I've ever met and he had 3 years of college before quitting for health reasons and needing cash too much to return), but I'm happy to miss out on them- a given engineer is more likely to be high impact with a degree than without, so again I'm using it as a good first screen to weed out the 90%+ who are useless in that category.

Now I have found some good engineers with alternative STEM degrees and a passion for coding- physics, EE, comp eng, mech end, etc. But you have to carefully screen to see if they actually know what they should, I would expect their math to be on par (or better), but not necessarily their knowledge of CS concepts.

he idea of moving the population to local cities where they can use public transportation especially in less dense areas like the United States, just won't happen.

Submission + - Google Strikes Deal With Verizon to Reduce Patent Troll Suits (wsj.com)

mpicpp writes: Google Inc. and Verizon Communications Inc. struck a long-term patent cross-license agreement to reduce the risk of future patent lawsuits, the latest in a string of deals that signal a slowdown after years of aggressive patent wars.

The deal effectively bars the companies from suing each other over any of the thousands of patents the companies currently own or acquire in the next five years. It also protects the companies if either sells a patent to another company, and that company attempts a lawsuit.

“This cross license allows both companies to focus on delivering great products and services to consumers around the world,” said Kirk Dailey, Google’s head of patent transactions.

Because you have to prove merit. A degree proves that you've studied the field for 4 years. A lack of degree show absolutely nothing. Thus to have equivalent background you have to show much more.

Now we have a pile of resumes. 50% of them have a college degree, thus 4 years studying the field. 50% do not (and don't have at least 4 years in the field professionally). I'm throwing out the 50% without a degree because the signal to noise ratio is too low. Will I throw out a few good hires? Maybe. But I'll throw out a lot of bad ones, and that's more important.

THat doesn't even get into the fact that school teaches different things. School teaches theory. The vast majority of self-taught programmers without a degree that I've seen are very weak on theory. They can maybe throw some libraries together, but they don't understand how to actually solve hard CS problems and couldn't explain basic concepts, causing their designs to have massive flaws. Many of them even take pride in this, their entire attitude being that they didn't need that "academic BS". These kinds of programmers tend to cost time and effort in the long run. So yeah, I'd rather have the degree and someone taught the theories behind everything than someone who thinks reading documentation on weekends will make him a good programmer. SO yeah, no degree means you better have a LOT of experience to even things out. I'm not going to hire you as anything but a web monkey if you have less than a decade.

Submission + - China officially became the world's largest economy, ahead of the United States

mrspoonsi writes: For the first time in 150 years, the USA has lost its title of the largest economy in the world to China. China officially became the world’s largest economy, ahead of the United States, according to the International Monetary Fund (IMF). According to the latest figures of the International Monetary Fund (IMF) just released in December 8th, 2014, China has come ahead the United States as the world’s largest economy. China’s GDP will indeed reach 17600 billion in 2014 against 17400 billion for the United States. These data are calculated using the method known as “purchasing power parity”, which is economically significant. It measures the purchasing power of different currencies in a common unit as opposed to changes in exchange rates. Now China represents 16.5% of the global economy in terms of real purchasing power, ahead of the US, 16.3%. According to IMF estimates, the gap should continue to widen in the coming years. By 2019, China would reach more than 26,800 billion of national wealth, against just 22,000 billion for the United States. The United States had become the leading economic power in 1872 after overtaking Britain.

You claim you can "just encrypt" your email, but it was the creator of lavabit, the "secure" email system that Snowden used, who stated essentially that email can NOT be made secure. It's not just a technology problem. When Secret Courts tell citizens they can't talk about Secret Orders, "encryption" isn't the solution. It's not just what you're saying, but with whom your talking to (e.g. metadata).

You may not agree with that, but you can't declare that no one else can believe it. You can read PJ's statement for yourself. You may not believe her, but you can't look into her heart and know that the reason she gave wasn't sincere:

Virtual Reality Experiment Wants To Put White People In Black Bodies 448

Molly McHugh (3774987) writes with an intriguing use of VR technology: "It's as simple as making a light-skinned person feel connected to a virtual, darker skinned self—a thought experiment pretty much impossible without the immersive potency of VR. The effect is achieved by outfitting participants in VR headsets with built-in head-tracking and motion capture capabilities that sync actual movement to virtual experience." From the article: Evolving from cruder methods, VR is a natural extension of research examining the ways that people think differently when made to feel like they are part of a meaningfully different social group, known as an outgroup. ... What’s most exciting about this channel of research is that it gets at the kind of complex, subtle prejudices that most people can’t even articulate if asked directly.
