Comment Re:Who's gonna pay "THEIR FAIR SHARE"?!?!?! (Score 2) 140

Tax cuts benefit those who pay more taxes - the rich. A family that exists just above the poverty line is not going to get anything back when they have their washing machine repaired. But a wealthy individual would get a significant amount back - hardly fair.

A better solution would be to increase the "environmental" tax and apply the additional tax revenue to pay for recycling and other environmental programs. Now everyone benefits equally. And by raising the price of appliances, the government would be promoting more repair and reuse of appliances.

The big change in DCDC design is in the different modes of operation that a DCDC controller can support. It used to be simple pulse width modulation but now we have pulse width modulation and, to use a term adopted by Linear, "Burst" mode DCDC converters. The purpose of the "burst" mode is to achieve low power level efficiency by on/off modulating the DCDC converter. The resulting on/off modulation can be within the acoustic range even if the actual DCDC converter is switching in the MHz range. So Linear, TI, Analog - they all now support their own version of a "burst" mode.

In the past 5 years, far more parts from various manufacturers are available for designing systems that goes to sleep but require always-on power rails. You used to have to pair a DCDC and LDO together to achieve the best of both worlds. And companies like Murata have capacitors specifically designed to assist in alleviating the whine. Check out their product line for a more detained description. I have designed and built power supplies that have had a noticeable whine - typically under low load. So I can confirm - it is the caps.

No, inductors do not make sound in modern DCDC supply. Blame can probably rest on the capacitors. The modern and tiny ceramic caps change shape slightly when charging and discharging. Every so slightly - but this causes them to rub against the board and generate a "hiss". There are caps designed specifically for power supplies that are supposed to prevent this. I recently purchased an Intel NUC and when you take a closer look at the board you notice that all the large caps are mounted on standoffs - raising them from the board so they do not hiss.

But Skylake IGP uses main memory. As such, use of the GPU can impact adjacent CPU functions due to limited memory bandwidth. A discreet GPU recovers the memory allocated by Skylake and minimizes contention for system memory. And let us not forget that many devices are limited by heat dissipation. Offloading the GPU helps minimize the heat generated within the CPU. The discreet GPU is a safer option - but I must admit the Intel GPUs are a desirable option for most users.

In the summary is specifically identifies "steed step technology" as being the big change. It will make no difference when gaming or running a server but laptops and other low power devices should get a big lift. Waking up faster implies the CPU can go to sleep (or low frequency mode) more frequently and total power consumption will be reduced. And for those who did not click on the article - delay was previously ~95ms and has been reduced to ~15ms.

Comment Re:Stealth (Score 3, Interesting) 117

An expensive plane with a "meat-sack" does not only have to be built strong, it has to be built to last. This results in larger development times and costs. One big advantage to an autonomous fighters that is rarely mentioned is that it does not have to last long. The aircraft can be designed to last 100 flights, not 10,000. This is because the planes would sit silent until needed. With piloted fighters, the pilots need regular training and practice using the same planes with which they will be fighting. With autonomous fighters the planes would almost never fly. Regular duties such as patrol could be taken over by simpler planes with lower maintenance costs where the full capabilities of a modern fighter are not required.

Hydrogen and electric are the only two vehicle choices that are carbon free. The oil/gas industry does not care which wins, they will supply the energy either way. It is the local governments that care because road infrastructure is largely paid for by fuel taxes. With hydrogen they do not have to change anything because they can tax hydrogen. Everyone going electric will require significant changes to how infrastructure is paid for.

Comment Re:Wikileaks: Propaganda arm of Russian intelligen (Score 1) 231

When Wikileaks publishes some stolen documents it is generally just for the purpose of being open. When Wikileaks times the publishing of certain documents to effect the democratic process, they are playing politics.

In addition, if Wikileaks publishes documents that have been filtered by a third party that wishes to effect the democratic process, Wikileaks is straddling the boarder of playing politics. Such posts need to be identified so the reader can take this into consideration. Otherwise Wikileaks is lying by omission - and as a result, playing politics.

I love an impartial Wikileaks. But a Wikileaks that plays with politics is utterly useless.

If connecting to a home stereo you could use an adapter / dongle. Better yet, a cable with the correct ports on each end. I assume you leave your cable connected to your home stereo. Be it a 1.8" cable or a USB-C cable, it does not make much of a difference when you are not carrying it around with you.

Comment Re:Renewables vs baseload (Score 1) 269

Used automotive batteries. Once they have been depleted to ~80% of their original capacity they are replaced. The old batteries can be recycled or reused in applications where weight and size are not as important as when used in automobiles. Storing excessing solar power appears to be an ideal application. One can only assume that this is why Tesla is getting into the home battery business. But Tesla does not make many cars. Once the big auto makers start releasing more electric vehicles there will be plenty of used automotive batteries available for storing renewable energy.

But that is due to power concerns. USH-II and UFS will both have the same problem because they both have the same form factor and basic signaling standards.. It will be a while before the benefits of a new bus can be realized when working with uSD sized cards. I assume most people will value power efficiency over speed so I would not expect this to make a difference any time soon. But if Intel's new memory works as advertised it might change things.
