Hell no. We are not talking about a 100W CPU/GPU, we are talking about a touch controller IC that uses almost no power. Thermal cycling due to regular use is not an issue. I am not saying that the solder connection is not to blame, just that the cause of the problem is not thermal cycling. If one is having repeated failures then they are obviously carrying the phone in such a way that it bends. The back pocket is the worst place to carry a phone, but the front pocket can also be bad. Some people do not even realize they are doing it. But one thing is certain, if you have 9 successive failures, it's you. Better odds of winning a lottery then having 9 successive failures -- or at least it is close.

I noticed that the iPhone 7 is not any thinner then the 6+. A tiny bit thicker even. This bodes well for the durability of the 7 so it is possible Apple learned from their mistake. Not that the 6+ is defective, but it could definitely be stronger.

ARC results in much lower latency when cleaning up memory. This results in better user interfaces and helps explain why it works well with iOS. The JVM employs garbage collection that offers better performance at the cost of higher latency. If you load balance multiple instances (as suggested by another poster) you get overall improved performance. The JVM is better suited for server applications where its garbage collection implementation is safer and requires less overall energy to perform a given job.

Your problems with Android will have more to do with API design and your approach to programming said APIs then they will the type of garbage collection used by the platform. I am not suggesting that Android is great, but it has been shown to work well if approached correctly.

Comment Re:Who's gonna pay "THEIR FAIR SHARE"?!?!?! (Score 2) 146

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.

Comment Re:Microarchitectural details? (Score 1) 95

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.

Comment Re:Driving yes, but charging?' (Score 2) 990

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.
