You do realize that anarchism is defined loosely enough to be quite inclusive of varying degrees of social control? The most anarchic anarchist society would end in mob rule, but few anarchists want that. Because of this you end up with a broad spectrum of people in the definition of 'anarchists'; those that want more municipal level communist elements to those who advocate strongly for primitivism, and also the "American" libertarians/AnCaps.

To my understanding, the policing model most compatible with "anarchism" would involve community selected individuals to be members of the police force. How practical of a model this might be is completely up for debate. The AnCaps would argue whoever has the money to pay for police deserve police...? Something like that.

AMD Details High Bandwidth Memory (HBM) DRAM, Pushes Over 100GB/s Per Stack 98

MojoKid writes: Recently, a few details of AMD's next-generation Radeon 300-series graphics cards have trickled out. Today, AMD has publicly disclosed new info regarding their High Bandwidth Memory (HBM) technology that will be used on some Radeon 300-series and APU products. Currently, a relatively large number of GDDR5 chips are necessary to offer sufficient capacity and bandwidth for modern GPUs, which means significant PCB real estate is consumed. On-chip integration is not ideal for DRAM because it is not size or cost effective with a logic-optimized GPU or CPU manufacturing process. HBM, however, brings the DRAM as close to possible to the logic die (GPU) as possible. AMD partnered with Hynix and a number of companies to help define the HBM specification and design a new type of memory chip with low power consumption and an ultra-wide bus width, which was eventually adopted by JEDEC 2013. They also develop a DRAM interconnect called an "interposer," along with ASE, Amkor, and UMC. The interposer allows DRAM to be brought into close proximity with the GPU and simplifies communication and clocking. HBM DRAM chips are stacked vertically, and "through-silicon vias" (TSVs) and "bumps" are used to connect one DRAM chip to the next, and then to a logic interface die, and ultimately the interposer. The end result is a single package on which the GPU/SoC and High Bandwidth Memory both reside. 1GB of GDDR5 memory (four 256MB chips), requires roughly 672mm2. Because HBM is vertically stacked, that same 1GB requires only about 35mm2. The bus width on an HBM chip is 1024-bits wide, versus 32-bits on a GDDR5 chip. As a result, the High Bandwidth Memory interface can be clocked much lower but still offer more than 100GB/s for HBM versus 25GB/s with GDDR5. HBM also requires significantly less voltage, which equates to lower power consumption.

What about the part that the wave is reflected back to the otherside of the cavity? Does it not just - reflect back and forth technically creating a net thrust of zero? I thought that guy claimed the slots inside the drive were the key to it's operation, yet the null device - one which did not contain the slots - worked the same.

Here's my past experience with microwave experiments: the damn things interferes with all your instruments in the most absurd of ways.

Don't believe me? Go take any normal voltmeter, remove the probe leads, and run the microwave with the door open (by passing the interlock of course) for just 5 seconds within a few feet of it - you'll get voltage reading. If you're not getting a reading then you are probably using a well shielded device - likely a Fluke or Keithley meter. Even those meters will likely show something still, I'd be impressed if they didn't.

So them measuring something like a few milliNewtons on a device that probably measures small signals and using even 50W in an enclosed cavity nearby - which itself will reemit some radio waves - on a metal table or in a steel vacuum chamber, where their own simulations show a large magnetic field gradient from one end of the device to the other - is enough evidence for me at least to show they're fooling themselves.

It's like every President since Kennedy felt they needed to give NASA some long term objective just to have the following Presidency give them something else, and have both House and Senate subcommittees give their two cents on objectives and funding.

It's just a recipe for the bullshit you see right now.

NASA needs to study the multivariable behaviour of Earth's climate to better understand the climate of other planets. It's cheap and easy, and provides lots of science relative to larger space exploration missions with limited capability. How the fuck can we make claims about a far off planet's atmosphere from light spectrum observations alone if we can't come to a consensus on our own planet's atmosphere?

Considering this audience is pretty much the only one that understands the implications behind these revelations. WE should be the ones raising the issues and getting in the government's face about this, but technologists are notoriously passive when it comes to protesting the government. With that in mind, there's not too much _I_ can do as a Canadian to protest the NSA/GCHQ, but there's definitely the CSE who are one of the "5 eyes" members.

However the easiest response to mass surveillance is mass encryption, and that doesn't involve standing outside for hours shouting at people who couldn't care less or trying to educate the average person about why this isn't just part of the fight on 'terrorism' but it's a direct assault on all of us. Obviously the entire cell phone network design will need an overhaul after these keys have been leaked, and hopefully the overhaul uses better techniques.

Mark Zuckerberg Throws Pal Joe Green Under the Tech Immigration Bus 261

theodp (442580) writes "A month after he argued that Executive Action by President Obama on tech immigration was needed lest his billionaire bosses at Mark Zuckerberg's FWD.us PAC have to hire 'just sort of OK' U.S. workers, Re/code reports that Joe Green — Zuckerberg's close friend and college roommate — has been pushed out of his role as President of FWD.us for failing to Git-R-Done on an issue critical to the tech community. "Today, we wanted to share an important change with you," begins 'Leadership Change', the announcement from the FWD.us Board that Todd Schulte is the new Green. So what sold FWD.us on Schulte? "His [Schulte's] prior experience as Chief-of-Staff at Priorities USA, the Super PAC supporting President Obama's re-election," assured Zuckerberg in a letter to FWD.us contributors, "will ensure FWD.us continues its momentum for reform." Facebook, reported the Washington Post in 2013, became legally "dependent" on H-1B visas and subject to stricter regulations shortly before Zuckerberg launched FWD.us with Green at the helm."

Astronomers Find Star-Within-a-Star, 40 Years After First Theorized 72

derekmead writes: After 40 years, astronomers have likely found a rather strange celestial body known as a Thorne–Zytkow object (TZO), in which a neutron star is absorbed by a red supergiant. Originally predicted in the 1970s, the first non-theoretical TZO was found earlier this year, based on calculations presented in a paper forthcoming in MNRAS.

TZOs were predicted by astronomer Kip Thorne and Anna Zytkow, who wasthen postdoctoral fellow at CalTech. The pair imagined what might happen if a neutron star in a binary system merged with its partner red supergiant. This wouldn't be like two average stars merging. Neutron stars are the ancient remnants of stars that grew too big and exploded. Their cores remain small — about 12.5 miles across — as they shed material out into space. Red supergiants are the largest stars in the galaxy, with radii up to 800 times that of our sun, but they aren't dense.
