Remember that Intel has a massive war chest from $1000+ server CPU sales and $300+ desktop CPU sales,

This is true, but if Intel does not design better CPUs in a timely manner then those sales are going to drop dramatically. This is precisely the problem they are now facing. People are not buying new computers because those new computers are no faster then their old computers. But they are buying new mobiles.

Intel is competing against themselves. Unless they expand into a new market, as they are attempting to do with the mobile market, then the limited PC market will result in their demise. They can no longer rely on improved manufacturing to grow their market because we are reaching the limit of what is practical to manufacturer. Intel needs to produce a product people will want in the future or they will die. Everything Intel is currently doing demonstrates that they understand this and are acting accordingly.

Multiple CPUs require the ability to synchronize cache. This requires more pins - a lot more pins. The A8x is already saturated with pins so adding this feature is not simple. A much better solution would be to remove the GPU and replace with additional CPU cores. Such a CPU could have 8 real cores and would post some impressive benchmarks.

Space is about the only place such clocks would be of any use. I could see them being used to provide GPS like localization services for any craft designed to leave earth's orbit. For it to work you require synchronized clocks. But, unlike GPS, there is no way to perform such a synchronization. You end up having to rely on the accuracy of the two clocks.

With the system in Canada there is always the possibility that someone bugs the Interac reader. Everyone using the machine will have their card number and pin stolen. The perpetrators then usually wait for some time, often years, then make purchases using your account. Waiting makes it more difficult for the police to track down the retailer that had their hardware bugged. Once identified the banks have everyone who used that machine change their pin code to prevent further theft.

This has happened several times in Canada. People have even installed fake bank machines designed for the sole purpose of stealing this information. Interac is great but still a big target for theft.

Apple Pay, and probably Google wallet, prevent this type of attack. Theft becomes a non-issue. So long as you do not have your phone stolen and fingers removed, your money is safe. This is a big improvement over Interac and will save a significant amount of money currently being spent on fraud prevention / compensation.

What we need is competition in this field. Let Apple have their system and let Google do whatever they want. Keep the hardware interface (NFC) standardized so that newer, better systems can be designed. Keep away from proprietary pay terminals. Multiple solutions should work with the available infrastructure thereby limiting the entry barriers when competing in this market. It will be interesting to see what gets developed.

An informed individual posted an explanation for this. Apparently, the new Intel chips have different pinout requirements between the dual core and quad core variants - this is assuming you are soldering the CPU directly to the motherboard. Because of this difference Apple can not sell a quad core CPU without designing a new motherboard. So they sell it with the fastest CPUs that operate within the given power constraints and supports the required physical pinout.

In all likelihood, Apple will release a quad core update sooner rather then later. Holding off for 6 months gives them plenty of time to design the new hardware while also giving them the opportunity to make headlines once again in 6 months time.

The Mac Mini is a great little design. If one is in the market and wants to get the fastest one possible, it is probably best to either wait or purchase a quad of the previous model.

The fingerprint is embedded within the SOC and not accessible from any API - a write only part of the device. It will accept new fingerprints and perform comparisons but never reveal any currently stored fingerprints. This is a dedicated piece of hardware and short of dissolving the package away to access the storage directly, there is no way to recover a fingerprint. Without the fingerprint, the encryption key associated with that fingerprint will never be released. One assumes the encryption key was randomly generated and of sufficient length so that it provides maximum security for whatever encryption algorithm was used to secure the device.

It would be cool to find out just what the real statistics are. I'm pretty sure, though, that Israel classifies this information as a state secret and we may never know in our lifetimes.

The rockets generate more psychological damage then physical. As far as weapons go, they are rather pathetic. All the iron dome really has to do is to make those it protects feel safe. If statistics have the potential of damaging this feeling of safety then you ca be assured that they will be kept secret.

The other purpose of the iron dome is to limit the desire to fire the rockets in the first place. If one thinks their efforts are in vain then they are less likely to follow through. If Israel can convince members of Hamas that their rockets are not working then there will be fewer rockets launched at Israel.

And hopefully in any lectures on Moore's Law, the students learn that Moore's Law refers to transistors on a die, not the speed of the chips. This 36-core chip probably jumps ahead of Moore's Law a bit, as it's got to be a fairly large die.

Moore's Law refers to the number of components per integrated circuit for minimum cost. Note that this is basically transistor density and is not impacted by core size. Silicon defects and transistor size determine the optimal number of components per IC.

A quote from Wikipedia,

Moore himself wrote only about the density of components, "a component being a transistor, resistor, diode or capacitor,"[26] at minimum cost.

With MIMO you have multiple channels

I was under the impression that MIMO gives you multiple antenna to facilitate beam forming. Channel bandwidth requirements do not change nor does the number of channels required. MIMO still only requires 1 channel. A quick wiki search appears to agree with this impression.

Now you can also use multiple channels but this is independent of MIMO technology. Both techniques can be used together - and typically are which might explain the confusion. Either that or I am confused which is always a possibility....

Don't see much need for high power output when Thunderbolt devices like displays will probably need their own power supply anyway.

It's not high power output - it's high power transfer. It will be used as single connection display / ethernet / webcam / USB Audio / power adapter when connecting your laptop to a monitor. Sort of like the ultimate dock.

I built a FreeBSD 9.1 file server using usb 3 / usb 3 docks, but I failed them all back down to using their 2.0 interface due to persistent flakiness/dropping off the bus type issues.

If you look at MacZFS you will notice that ZFS over a USB bus is garbage. Far too many problems - developer says to not even bother reporting the bugs. And in my experience, FreeBSD is not much different in this regard. Had major problems with ZFS over USB while UFS appears to work fine. Use a different connection, like eSATA or Firewire, and ZFS starts to work again.

I only mention this because it is quite possible that USB was working fine. Glitches / delays / disconnects, regardless of which layer they originate in, appear to hit ZFS hard. Better to use eSATA if you have a FreeBSD box.

The graph has a logarithmic horizontal scale. As a result, the deviation of sea level from thousands of years ago is calculated over a larger time from then the deviation reported for today. If the deviation for today was calculated using the same time frame it would be significantly larger then the value calculated for thousands of years ago. The fact you did not see this is somewhat disturbing and could just explain why you are arguing your point. Or you're a troll - you're probably just a troll - people on this site can not be that foolish.

The real question is how efficient is it?

It does not have to be any more efficient if they manage to reduct weight and increase reliability. Efficiency has a big part to play but even a less efficient engine would be desirable if they improve greatly on other aspects.

Remember that this is being targeted for vehicles that will run mostly on electric power. An ICE is a dead weight when not being used. If someone drives using 90% pure electric then the efficiency gains of carrying less weight could easily outweigh the losses of an ICE that was 5% less efficient but only operates for 10% of the time.
