Comment Re:Actually there's 5 chipsets (Score 1) 71

Not really, considering the processor give you 24 3.0 lanes. That lets you do graphics (or a bridge for crossfire/sli enabled boards) and NVMe at full speed, and leaves 4 lanes (4000MBps each way) to communicate with the chip-set (which can talk to other peripherals via 8 pci-e gen 2.0 lanes. It really should be plenty for most use cases. The i5-6700 only has 16 lanes coming off the chip directly, and and the DMI equivalent fo 8 lanes talking to the chipset. The z270 chipset adds another 4 lanes, but the DMI is the same speed. Amd having lanes dedicated to the nvme drive could help in some benchmarks. All in all you can hook more things onto the Intel chip-set, but raw communication speed isn't much better, if you assume that 1/2 of the transfer is going to be to/from an nvme drive. I think it's a good strategy as even though the x370 is the premium chip-set, it should be quite a bit cheaper than the Intel z or x series, while still delivering the features that enthusiasts like.

Submission + - Why You Shouldn't Trust Geek Squad (

An anonymous reader writes: The Orange County Weekly reports that Best Buy's "Geek Squad" repair technicians routinely search devices brought in for repair for files that could earn them $500 reward as FBI informants. This revelation came out in a court case, United States of America v. Mark A. Rettenmaier. Rettenmaier is a prominent Orange County physician and surgeon who took his laptop to the Mission Viejo Best Buy in November 2011 after he was unable to start it. According to court records, Geek Squad technician John "Trey" Westphal found an image of "a fully nude, white prepubescent female on her hands and knees on a bed, with a brown choker-type collar around her neck." Westphal notified his boss, who was also an FBI informant, who alerted another FBI informant — as well as the FBI itself. The FBI has pretty much guaranteed the case will be thrown out by its behavior, this illegal search aside. According to Rettenmaier's defense attorney, agents conducted two additional searches of the computer without obtaining necessary warrants, lied to trick a federal magistrate judge into authorizing a search warrant for his home, then tried to cover up their misdeeds by initially hiding records. Plus, the file was found in the unallocated "trash" space, meaning it could only be retrieved by "carving" with sophisticated forensics tools. Carving (or file carving) is defined as searching for files or other kinds of objects based on content, rather than on metadata. It's used to recover old files that have been deleted or damaged. To prove child pornography, you have to prove the possessor knew what he had was indeed child porn. There has been a court case where files found on unallocated space did not constitute knowing possession because it's impossible to determine who put the file there and how, since it's not accessible to the user under normal circumstances.

Yes, zen does have full fpu's in each core (2x 128 bit add and mul), or can be scheduled as a single 256 bit FMA operation. A good micro-op cache, and two threads per core possible when SMT is enabled. (should be unless you turn it off, as some unusual chache intensive and context sensitive processes perform better with it disabled. )

It's a potential issue, admitted right in the configuration file.

1. One option for mitigation, even in the worse-case scenario is planetary albedo modification via nano-engineered particulates injected into the upper atmosphere. Best case scenario is 0.5-1.0 C, which isn't catastrophic. Food production may slack 10% in the middle case, which a shift to more efficient protein could overcome.
2. Yes, there and many sorts of costs, one of which is opportunity costs. Driving the market to a dead-end is silly. 3. Fission is still 30 years of so off. Gen IV Fusion reactors are viable and could be build in scale in the next 10-15. And the high-temp of some of the designs can be used to efficiently synthesize transportation fuels that are easy to use and drop into current infrastructure. Hydrogen is difficult to store and transport reliably in large quantities dues to low density, small molecule size, and metal embrittlement. The best thing going for it are fuel cells, but the cells aren't all that durable and are quite expensive. CNG could be a lower Carbon bridge, but it suffers many of the same infrastructure and density issues.
4. In terms of density and Return on energy invested, they definitely are. They are also not "on demand", which brings a plethora of challenges and added cost to the infrastructure.

1. Planet destruction is hyperbole. There is literally nothing than man knows how to do than can destroy the planet. It will warm some, the amount is contested, but even granted that, there is every indication that the cost of mitigation and adaption are less than the cost of a move to non-nuclear renewable.
2. Right now the cheapest source of hydrogen is to strip it from natural gas. In practice it's still a fossil fuel.
3. Using the heat from high-temp nuclear would let you synthesis fuels with higher energy densities, that are much easier to transport and store, and can be run in conventional engines with little modification. Methanol, Dimethel ether, and ammonia are potential candidates. Heck the navy is even has some success with JP8.
4. Moving from fossil fuels to wind and solar is a step backwards. Nuclear is the way forward for reliable energy and property. If the U.S doesn't do it, India and China certainly will.
