Of course no one can spoof GPS, oh wait....never mind I was doing that over the weekend with my SDR.

Indeed, this loud wince of pain from the Navy smells like it may be impinging more than just weather sats.

As I recall the Lucasian Chair is well respected, but hard to get. Previous iteration was string based, but since 2015 its a more of comfortable soft condensed matter thing.

Security! Seriously, Worry about the whole damn RF signal as it is probably the only 900 MHz around for miles. Even if it is spread spectrum it should not be too hard to track in the Savannah.

This is news?

I'd swear that bad actors use The Onion for ideas.

ECDIS does much more than just simple google style nav. ECDIS also understands ship draft, water depth, turning radius, etc and is designed to keep the ship from doing something stupid like the Valdez did. ECDIS also looks for dynamic collision dangers fro other ships with radar feeds. So even if a ship has paper charts, the regulators, insurers or owners will not risk a drowsy watch running into a rock thus risking life, limb or billion dollar damage/fine payout. Would you fly intercontinental if you knew the plane only had paper charts and a sextant?

Currently, the gentrification process is 1) upgrade buildings then 2) import gentry. I would propose that we 1) Upgrade the people in-place then, 2) upgrade the buildings. Lets invest in the people that already live somewhere and then let them upgrade their buildings. Give that rundown neighborhoods tend to have rundown schools we owe these residents a lot for failing to invest in them while they were young.

Run GCC and have enough memory to compile its own Android OS. If not it is not a "real" computer.

W3Woody,
All good points as GPS is such a weak signal it does offer lots of opportunity for mischief. There is also the risk of someone with physical access reprogramming the avionics - think cleaning crew. Change one byte on a scaling coefficient on a fuel calculation then 1000 miles from land you are suddenly running on fumes. There are also multiple RF data links to the ground, but most of them are relatively low band width. Of course there is the whole electronic flight bag used to replace maps, that are basically just PCs and ripe to get hacked - don't connect to the plane, but still pilots base many decisions on them. The Internet connection everyone thinks about in the pax cabin is air-gaped from the avionics except for a one-way serial connection feeding nav data from the avionics to the IFE (In Flight Entertainment) to display the you are here map.

The tech community in general is more educated and mere diverse (in some ways) than the general population and hence much less will to support trump. Plus tech CEOs are not psychologically the types to kiss the kings ring so yes, he is about to screw tech for both fun and profit. Probably he will use as leverage to extort more personal gain out of Beijing.

Finally, one less thing to root around for in the morning to make me late for work. I really want to throw away my keys and wallet. I can remember arcane bits of 60's sitcom trivia and Maxwell's equations, but I never seem to remember where I put and keys and wallet the night before. There have been halting efforts for digital driver's licenses. Of course, loose your phone then and you are deeply hosed. With no wallet, good luck getting money from the bank to buy a new phone (master digital token) to bootstrap you life back. Plus, I've always hated badges ("we don't need..."). Once everyone is opening doors with phones there will less and less argument for those horrible status symbols hanging off your belt - and one less thing to forget in the morning.

To be a bit pedantic, they do not interoperate as they need a bridge device that can receive/translate a message form one protocol to the other and retransmit it. Completely different modulation, etc. Plus most consumer IEEE-802.15.4/ZigBee devices are going to run at 2.45 GHz (ZigBee does have a few channels at 902) and Z-Wave runs at 902MHz.

I think 10 bumper stickers should be more than enough to uniquely identify most cars.
You obviously have not visited the Fremont area of Seattle.
