Of course it would be cooler if only small badges of devices had the same cert, or if you even would go through the hassle to make individual ones.

Going through this hassle is exactly what is typically done. It is not uncommon for the initial - or post reset - boot of a router to take significantly longer then subsequent boots. This is when the router generates the public / private key combination. I suppose that the manufacturers are bypassing this to simplify support. Alternatively, they are truly incompetent and simply flashing the devices with a firmware that already contains the certificate. But each device should have a different serial number which should invalidate a copied certificate. So they must be going out of their way to facilitate a common certificate. Possibly they disabled verification against the serial number?

Regardless of why or how they are doing it, a common certificate indicates a common private key. With that private key you can decode the shared AES (or DES) key and subsequently decode all network traffic. The key will be stored in FLASH memory and can be accessed via JTAG connection.

Comment Re:Why are resistors needed in a cable? (Score 2) 206

And this helps how? Neither the device or host have knowledge of the cable that connects between them. Only by embedding this information into the cable can the two devices negotiate power settings that conform to the physical connection. The only alternative is to force active cables - such as Apple's lightning connector or Intel's thunderbolt connector. While this is not a horrible idea, it will not lead to low-cost cables.

or VW could offer an alternative. A new firmware and X dollars refunded to compensate for lost milage / reduced resale value. If they offered enough then people would accept the deal and problem solved. It will cost VW a significant amount of money but would save them in the long run.

Many VW owners would likely see it as a net-gain. Especially those who, after getting the new firmware and compensation check, revert back to the more efficient firmware.

Comment AFV - needed.. (Score 1) 151

AFV - autonomous fuel vehicle. Why send all the fuel with the astronauts? Send multiple smaller fuel tanks ahead of time and have them go into orbit around Mars. This should greatly reduce the risk of such a mission. Hell, do not send astronauts until you have first verified that 150% of the fuel required has already been successfully put into Mars orbit. Then when humans do go to Mars (if it ever happens), first have then sit in orbit using a robotic workforce to construct whatever planet based infrastructure they require. Only when everything is done should humans step foot on Mars.

Comment Re:either integrated Intel HD Graphics 530 or a po (Score 1) 94

Will depend on the OS. The MacBook Pros have had this for some time and MacOS will use the dedicated GPU in certain situations. Depends on many factors - what the application requires, is the computer plugged in, how much battery life is available... Apple has more control of software and hardware so implementing this sort of solution is easier for them. I've heard some complaints but not too many. Do not know how Windows manages this. And Linux? Without capable hardware in the hands of developers one can not expect much progress. And considering the perpetual state of video drivers on Linux.....

But as far as the hardware goes, the integrated GPU is going to be available even if when the external GPU is present. It is likely Dell uses the same motherboard for both laptops - they just neglect to install the external GPU in certain models. This is how manufacturers typically approach this problem.

Comment Re:OS/X on A* CPUs? (Score 1) 213

Backwards compatibility is worth more then extra battery life. The A series CPUs are excellent and I am certain they cost Apple less then the Intel chips but adopting them for current products would cause too much grief. Intel is still improving their CPUs and not forcing Apple to switch architectures.

For new platforms, the A series CPUs are an obvious choice. I could see a version of MacOSX being ported to the latest large iPads. In time, the software ecosystem would develop to support the ARM CPUs and eventually, an ARM laptop could be viable. But this would take some time and would require Intel to drop the ball. I do not personally see it happening anytime soon.

No, but the technology used to make a "swarm" work is required if you want drones to operate alongside regular aircraft - ex, Search and Rescue. Remember the fires in California where the water bombers had to turn away because drones were taking photos of the fires? It was not due to a lack of airspace - it was due to the inability to guarantee that the drones would not impact the water bomber. "Swarm" technology could provide that guarantee.

Gas stations of the future will not exist unless they are selling gas. The demand for electric charging will not be great enough because the majority of people will charge at home. Competition from restaurants and other service providers will also be present since providing electricity does not require the infrastructure and safety certification required for selling gasoline - at least not if you are charging slow. Some fuel stations supporting fast charges will likely exist but they will not be common and will likely charge a premium for a charge due to the increased cost of the charging infrastructure. The desire to save money will cause people to adapt their driving / charging habits so that fast charges are not required.

Comment Re:ZFS (Score 1) 212

If you want per-application snapshots then you want the application to be in charge of the snapshots - not the file system. The file system does not know when an application is finished making changes to a file. Possibly many files must be changed - the file system does not know so it can not make any assumptions. Applications should be in charge of their own document snapshots using some form of version control. If one wanted they should script it so that a ZFS snapshot was generated - but you are better of using git.

With regards to ZFS, the snapshots are generally done at whatever frequency is defined by the administrator. 5min, 30min, 1day - whatever they decide. The snapshots are accessed from the root ".zfs/snapshots/named_snapshot" directory. There is no piecing together of files - the full file-system, as it was at the point in time it was captured, is available in the directory. The snapshots are immutable - the contents will never change so long as the snapshot exists.
