FPGA are closer to ASIC then CPU's. But an ASIC will still run much faster then FPGA programed to the same circuit as there is still all the logic connectors between the gates that the signals would need to propagate thru, not to mention that the gates are would be physically further apart. On a ASIC there are only the proper connections, and the gates much more optimal layout minimizing the distance the signals have travel.

Raw clock speed is raw clock speed, but at a certain point the resources needed to push the clock speed higher are not economical. The chip runs too hot and draws too much power. So adding extra cores makes more sense as the power demand will go up, more or less. linearly with processing power. It might even make sense to slow the default clock speed to be able to add more cores. Your clock speed will go down, but you processing speed, (ie # of instruction completed per second) will go up.

Yes there is some overhead in having to parallelize stuff, but even with that your still going to be ahead of the game.

Raw Clock speed has been meaningless for the last few chip generations. And actually dropped a few gens ago. All for the sake of efficiency. The as speed goes up power consumption goes up exponentially. But the same works in reverse, by lowering speed a little bit you get a huge savings in power, which allows you to do stuff like add additional cores. So while raw speed goes down total computing power goes up. This just seems like more of the same.

Sadly any answer probably boils down to the fact that not enough people have been injured and/or died yet. Hang a few bodies around the problem and you can bet the government will start taking security on these devices much more seriously. Hang a few lawsuits on them and the companies might do something about it themselves.

UK Man Gets Britain's First-Ever Conviction For Illegal Drone Use 77

jfruh writes: Nigel Wilson of Nottingham was quite a drone enthusiast: he flew a drone over a Champions League soccer match low enough to startle police horses, and at other times flew drones over iPro Stadium in Derby, the Emirates Stadium in north London, and near the Houses of Parliament, Buckingham Palace, the HMS Belfast and the Shard tower in London. He's been convicted under the Air Navigation Order 2009 and fined £1,800.

The Lies Disks and Their Drivers Tell 192

davecb writes "Pity the poor filesystem designer: they just want to know when their data is safe, but the disks and drivers try so hard to make I/O 'easy' that it ends up being stupidly hard. Marshall Kirk McKusick writes about the difficulties in making the systems work nicely together: 'In the real world, many of the drives targeted to the desktop market do not implement the NCQ specification. To ensure reliability, the system must either disable the write cache on the disk or issue a cache-flush request after every metadata update, log update (for journaling file systems), or fsync system call. Both of these techniques lead to noticeable performance degradation, so they are often disabled, putting file systems at risk if the power fails. Systems for which both speed and reliability are important should not use ATA disks. Rather, they should use drives that implement Fibre Channel, SCSI, or SATA with support for NCQ.'"

Most of that dust is probobly on the stationary part of the fans. The main idea for this heatsink is that the HEATSINK doesn't get as much dust on it. Take a look at most fans they get some dust on the blades, but it doesn't really build up over time, as compared to the dust that accumulates on the stationary fins of a standard heatsink.

In no way is this like a Boundary Drag Pump. It has blades, the defining characteristic of a Tesla pump is that it DOSEN'T have blades. Yes they both talk about the boundary layer effect, but the heat sink is trying to minimize it as it impeads heat transer to the air, while a tesla pump tries to maximize it as that is how the pump transfers motion to the liquid.
