Submission + - Bill Nye Botches Deflate-Gate Science 1

spiedrazer writes: It looks like America's favorite non-scientist science authority has weighed in on the physics of the NE Patriots Deflate-Gate "scandal", saying that to change the pressure in a football, you need to have a needle to either let air in our out. This, of course, completely ignores the Ideal Gas Law and the effect that changing temperature would have on the pressure of the gas within the ball. MIT did a "slightly" more scientific look at the physics here and found a pretty significant effect.

I didn't realize that Bill Nye had so little science background, but from his wikipedia page: "Nye began his professional entertainment career as a writer/actor on a local sketch comedy television show in Seattle, Washington, called Almost Live!. The host of the show, Ross Shafer, suggested he do some scientific demonstrations in a six-minute segment, and take on the nickname "The Science Guy".[14] His other main recurring role on Almost Live! was as Speedwalker, a speedwalking Seattle superhero."

Comment Re:Windows 10 (Score 1) 135

moot point. it will probably cost you nothing, because if you are running XP, you aren't buying this. If you are running XP, then you are buying a new machine and chances are it will come with either a recent OS or 10 itself.

People with old machines building their own new machines and getting 10 will be in the minority. Tip: get a cheap 7/8.1 license to upgrade for free to 10.

Submission + - Ask Slashdot: GPU of choice for OpenCL on Linux?

Bram Stolk writes: So, I am running GNU/Linux on a modern Haswell CPU, with an old Radeon HD5xxx from 2009. I'm pretty happy with the open source Gallium driver for 3D acceleration.

But now I want to do some GPGPU development using OpenCL on this box, and the old GPU will no longer cut it. What do my fellow technophiles from slashdot recommend as a replacement GPU? Go nVidia, go AMD, or just use the integrated Intel GPU instead? Bonus points for open sourced solutions. Performance not really important, but OpenCL driver maturity is.

Submission + - Barrett Brown, formerly of Anonymous, sentenced to 63 months

An anonymous reader writes: Barrett Brown, a journalist formerly linked to the hacking group Anonymous, was sentenced Thursday to over five years in prison, or a total of 63 months. Ahmed Ghappour, Brown's attorney, confirmed to Ars that Brown's 28 months already served will count toward the sentence. That leaves 34 months, or nearly three years, left for him to serve. In April 2014, Brown took a plea deal admitting guilt on three charges: “transmitting a threat in interstate commerce,” for interfering with the execution of a search warrant, and to being "accessory after the fact in the unauthorized access to a protected computer." Brown originally was indicted in Texas federal court in December 2012 on several counts, including accusations that he posted a link from one Internet relay chat channel, called #Anonops, to another channel under his control, called #ProjectPM. The link led to private data that had been hijacked from intelligence firm Strategic Forecasting, or Statfor.

Submission + - Quantum Computing Without Qubits (quantamagazine.org)

An anonymous reader writes: For more than 20 years, Ivan H. Deutsch has struggled to design the guts of a working quantum computer. He has not been alone. The quest to harness the computational might of quantum weirdness continues to occupy hundreds of researchers around the world. Why hasn’t there been more to show for their work? As physicists have known since quantum computing’s beginnings, the same characteristics that make quantum computing exponentially powerful also make it devilishly difficult to control. The quantum computing “nightmare” has always been that a quantum computer’s advantages in speed would be wiped out by the machine’s complexity.

Yet progress is arriving on two main fronts. First, researchers are developing unique quantum error-correction techniques that will help keep quantum processors up and running for the time needed to complete a calculation. Second, physicists are working with so-called analog quantum simulators — machines that can’t act like a general-purpose computer, but rather are designed to explore specific problems in quantum physics. A classical computer would have to run for thousands of years to compute the quantum equations of motion for just 100 atoms. A quantum simulator could do it in less than a second.

Submission + - The camera that changed the Universe

StartsWithABang writes: As the Hubble Space Telescope gets set to celebrate the 25th anniversary of opening its eyes to the Universe, it's important to realize that the first four years of operations were kind of a disaster. It wasn't until they corrected the flawed primary mirror and installed an upgraded camera — the Wide Field Planetary Camera 2 (WFPC2) — that the Universe truly came into focus. From 1993 to 2009, this workhorse camera literally changed our view of the Universe, and we're pushing even past those limits today.

Submission + - Sen. Sessions, calls STEM shortage a hoax, appt to head immigration (computerworld.com)

dcblogs writes: The Senate's two top Republican critics of temporary worker immigration, specifically the H-1B and L-1 visas, now hold the two most important immigration posts in the Senate. They are Sen. Chuck Grassley (R-Iowa), who heads the Senate's Judiciary Committee, and his committee underling, Jeff Sessions (R-Ala.), who was appointed by Grassley on Thursday to head the immigration subcommittee. Sessions was appointed one week after accusing the tech industry of perpetuating a "hoax" by claiming there is a shortage of qualified U.S. tech workers. "The tech industry's promotion of expanded temporary visas — such as the H-1B — and green cards is driven by its desire for cheap, young and immobile labor," wrote Sessions, in a memo he sent last week to fellow lawmakers. Sessions, late Thursday, issued a statement about his new role as immigration subcommittee chairman, and said the committee "will give voice to those whose voice has been shut out,” and that includes “the voice of the American IT workers who are being replaced with guest workers."

Comment Science and politics are orthogonal (Score 1) 497

The point to the vote wasn't to establish the science. It was to provide an argument to politicians that this issue is real. Poltiicians don't understand science so the argument they use is political.

A senator may well want to argue that the science is wrong. It's a lot harder to argue that democracy is also wrong.

Of course we don't like this. Slashdotters like science. Many of us are scientists. This is a terrible way of carrying on, but the important issue is we deal with the environment. If we need to back up our scientific argument with a political one, so be it.

Comment Re:Congress'l approval rating near all-time low (Score 1) 667

If the American public truly believed, so overwhelmingly, or cared, Congress wouldn't have an incumbency rate of somewhere between 96 and 85 percent (depending on how you count.)

America doesn't have elected officials, they have an aristocratic class, and a few political dynasties.

Comment Re:Free upgrade for one year (Score 1) 570

Which can be rewritten as 'Microsoft specified it would only be free for the first year, which I interpret to mean that there will then be a yearly fee.'

The other, more logical, interpretation is 'After a year, even if running windows 7, 8 or 8.1, you'll need to purchase an upgrade at standard retail.'

Comment Re:What Kind (Score 1) 386

The thing about a String type is that it's a common means of sharing data, but there are dozens of incompatible implementations. Qt uses QString, I remember using a regex library that uses a UnicodeSting type, and I've worked with more than one toolkit that uses its own custom string class. Mixing and matching these can be a headache.

Complex types are less of an issue because they're a lot more specialised. You're more likely to want to read a value from a widget input field, parse it using a regex and then use the result in a third library than to do the equivalent with a complex number. I'll grant you, this is more of a perceived problem with std::string than a fundamental issue with C++ but still, I rather like the fact that any Java library I use will use java.lang.String if it needs a string.

Comment Re:What Kind (Score 1) 386

No built in string. Complicated templates mechanism. A lot of C legacy crud. Antiquated #import system (the main issues is that this can lead to horrendous build times). Not sure if these are better in D, but they are problems that it would be nice to address.
