Comment Re:How do they calculate the upper bound? (Score 5, Informative) 210

As said at http://cms.web.cern.ch/news/cms-search-standard-model-higgs-boson-lhc-data-2010-and-2011, they have excluded 128 – 525 GeV at 99% confidence level. I am not sure they measure higher than 525 GeV with LHC for now. I would expect that existing theories for the Higgs put limits on its mass. Of course theories can be wrong, but if all theories about the Higgs are wrong, then there is no such particle.

There is no way heat could cause a nuclear decay unless you get to 50 million Kelvin or so. With a laser it could conceivably be done, if the laser is powerful enough to reach that temperature. The reason is that things happen in the atom's nucleus, and you need to interact with via strong and/or weak forces (don't remember the details), not electromagnetism. Neutrons can do it, but that means radiation. Since the article doesn't say where the energy comes from, it's surely a scam.

Submission + - Instant Quantum Communication Is Near (popsci.com)

fljmayer writes: In this experiment, researchers in Australia and Japan were able to transfer quantum information from one place to another without having to physically move it. It was destroyed in one place and instantly resurrected in another, “alive” again and unchanged. This is a major advance, as previous teleportation experiments were either very slow or caused some information to be lost.

Comment Where is the useful information? (Score 1) 469

I haven't sifted through the actual information, but my impression right now is that the leaked information is mostly embarrassing gossip, with very few actually interesting revelations. If things stay that way, it seems childish to piss off so many people by publishing private communication. I would hate to see WikiLeaks degraded to the level of tabloids, but right now they seem to be on their way.

Submission + - h264 permanent royalty moratorium announced. (arstechnica.com) 1

vistapwns writes: MPEG LA has announced that free h264 content (vs. paid h264 content which will still have royalties) will be royalty free forever. With ubiquitous h264 support on mobile devices, personal computers and all other types of media devices, this assures that h264 will remain the de facto standard for video playback for the foreseeable future.

Comment Re:Missing option: Autopilot! (Score 1) 789

That's what I wanted for while, too. Finally I could do something else on those long drives! I really can't wait for this, but unfortunately I am not sure I will live to see it in action, not least because of the legal ramifications. Which car maker wants to be sued first for an (alleged) autopilot malfunction?

The Proton Just Got Smaller 289

inflame writes "A new paper published in Nature has said that the proton may be smaller than we previously thought. The article states 'The difference is so infinitesimal that it might defy belief that anyone, even physicists, would care. But the new measurements could mean that there is a gap in existing theories of quantum mechanics. "It's a very serious discrepancy," says Ingo Sick, a physicist at the University of Basel in Switzerland, who has tried to reconcile the finding with four decades of previous measurements. "There is really something seriously wrong someplace."' Would this indicate new physics if proven?"

Submission + - Can Ubuntu Save Online Banking? (computerworld.com)

CWmike writes: Rob Mitchell writes, I do my online banking from the same home computer the rest of the family uses for Web surfing and online games. I have the McAfee security suite loaded and do regular scans so accessing online banking should be protected. Right? Not really, says Jay McLaughlin, CIO of CNL Bank. Accessing online banking from your everyday PC is just asking for trouble, he says. Recognizing that most consumers don't want to buy a separate computer for online banking, CNL is seriously considering making available free Ubuntu bootable 'live CD' discs in its branches and by mail. The discs would boot up Linux, run Firefox and be configured to go directly to CNL's Web site. 'Everything you need to do will be sandboxed within that CD,' he says. That should protect customers from increasingly common drive-by downloads and other vectors for malicious code that may infect and lurk on PCs, waiting to steal the user account names, passwords and challenge questions normally required to access online banking. Who knows? I might decide that I like running Linux for more than just online banking, Mitchell writes.

Comment Depends on how you run your business... (Score 2, Insightful) 364

Most of the things he complains about would be bad practices for any business. How can a business keep customers at arm's length and expect to have a good relationship with them? How can a business let its customers completely dictate how they do their work? If you run a business, you are responsible for keeping it sustainable, and sometimes that means you have to say no to your customers.

Comment Re:More than a million? (Score 1) 395

At a glance, nearly 50% of my source code lines are either empty or contain just a '}'. I use an IDE which generates a lot of code for me. And 'find . -name *.java|xargs wc -l' on a hobby project I have been working on for several years results in 110185 lines. So 1 million lines doesn't sound like a problem at all.
