Once you ban a technology, you are also banning any development on it.
Even if diesel cars are banned, diesel engines will certainly remain extensively in-use. Semi trucks, stationary electrical generators, train locomotives, massive container ships, etc.
American phone companies don't use metered data, they use tiered data, and if you had that sort of plan for power or water you'd be very upset the moment your routine changed.
Have you ever paid a utility bill? Both my electric and water bills have always had 4 tiers... At the high-end, you'll be paying more than double the rate of the lower allotments. A big reason why so many people are installing solar panels, is because shaving just a few percent off the top of their electric bill will save them a LOT of money.
San Fran may be crazy anti-housing, but a motivated company could skirt the rules and build a "parking lot" for their employees, which just happens to work well for employees with RVs.
It would need convenient proximity to an RV (sewage) dumping station, which doubles as a water supply. Nearby propane refuelling station, or even a full-for-empty tank swapping kiosk would fill-out the picture. That and space is all you strictly need. Nearly all RVs are designed for this off-grid mode of operation.
30A electric hookups would sure be nice, but if you can't get that through, solar panels on the roof would do a good enough job. Very small propane-powered generators can do the job of backup power supply.
Personally, I'd prefer to see some cheap capsule apartments...
"The car is so very silent when driving that minor squeaks and rattles that you wouldn't be able to hear in a gasoline engine car become very annoying."
That's only true at low speeds. At highway speeds, 3/4s of vehicle noise comes from tires on the road (trapping pockets of air as they roll), not the engine. That's why those sirens on EVs like the Leaf can shut-off above 35MPH, and why you still don't want to live near a busy road in an all-EV future...
Some design changes to roads have been tested, but the improvements are small.
If you want a notably quieter future car, you need to hope airless tires advance quickly and eventually surpass current pneumatic tires everywhere.
That's not what training time is meant to be focused on. People say the military is too focused on fighting the LAST war, but the navy seem intent on fighting the last-century's wars...
If the navy decides that a certain skill is _NEEDED_ then in your position (with no knowledge what so ever about maritime topics) I would suggest to trust the Navy.
Your appeal to authority is a pure fallacy. The Navy is a huge organization, filled with plenty of dead-weight and led by a string of idiot politicians. No doubt it was one of those many useless morons that got it back on the agenda, not any actual need.
The fact that NOBODY here has come up with one good sane reason this is NECESSARY (including you), is a good indicator of that fact.
I couldn't care less about the opinion of someone who received the product just because they're considered a good reviewer in general - what a dumb concept!
It's generally a good idea. When a product first shows up on Amazon, it starts with no reviews and won't get much notice. Seeding the reviews section, by people known to write good product reviews, is helpful to everyone. Of course, AFTER there's plenty of reviews, that process should stop, but sellers keep handing out free products to keep their product ratings up.
Amazon explicitly allows this, which I guess is better than driving it underground, but does nothing to account for this heavy reviewer bias:
"if you offer a free or discounted product in exchange for a review, you must clearly state that you welcome both positive and negative feedback. If you receive a free or discounted product in exchange for your review, you must clearly and conspicuously disclose that fact."
I've seen MANY products whose 4.5 star averages are purely because the seller sends out tons of free samples in exchange for positive reviews. Meanwhile, products that are considerably less expensive but don't bribe their customers unfortunately get less prominently featured in search results because their average rating, sales counts, and review numbers are so much lower.
Please give advice only about stuff you know about.
Okay. I'm an engineer for a major company in GPS navigation & guidance. It's true I'm usually doing this stuff in relation to automobiles, not sailboats, but we're talking about military vessels, not sailing, anyhow.
It is pretty hard to get into a life boat and not have a sextant and maps. They are stored in the craft
And so is a handheld GPS... I was asking the parent to explain how the GPS unit got lost, but the sextant (and a trained navigator) did not.
Unused LSD NiMH batteries hold a charge for 2+ years. A small solar panel could keep recharging them, keeping your spare hand held navigation system operating, indefinitely.
Anyway, what is your damn problem?
It's an absurd, wasteful reaction to a non-problem, which provides basically no benefits.
How would you feel if modern Linux certification required a Morse Code signalling & equipment maintenance course? You know... just in-case the internet goes down.
I have to pay over $1000 to learn it (and get the certification), and those guys get it for free and you complain about that? How dumb is that?
No, they don't get it for free. I'm paying for their training (which I'm betting they don't want), and all the time they waste that could be better used. All for no benefit to anyone.
I think that's the polite way of saying "because the enemy may be able to hijack the signal."
Also no:
"because it can be used by potential enemies" -Navy Capt. Terry Carraway
The big security controversy when GPS became public was that it's much cheaper and easier to make a GPS-guided missile than a cruise missile: "All normal GPS receivers got two limits build into them [...] a speed and height limit so no receivers can be used in automatic guided weapons"
Let's also consider a situation given in the linked article, the ship is fully operational but the Navstar GPS satellites are disabled. A GPS unit wrapped in aluminum foil won't save you then.
That's simple, really. Ships should have radio direction-finding equipment aboard, as a backup. There's no reasonable situation in which all major broadcasters stop transmitting (and the ship's navigation remains urgent), so they'll be able to find their way, day or night, in any kind of weather & heavy cloud cover, and far more accurately than cellestial navigation.
What if the issue is not lack of GPS but lack of electrical power?
Then you'd better call out the galley slaves with their giant wooden paddles, because I can't imagine any scenario where a ship's engine would be operational, but they couldn't generate a few watts of electricity out of it.
Hell, this is the military, they don't mind forcing a few men to turn a crank on an alternator around the clock, to generate a little power, when needed. Seriously, who is teaching celestial navigation, instead of just including a $30 solar panel as a tertiary backup power source in the event of inconceivable system failures?
Or, in the case of an EMP, the computers are scrambled?
We aren't talking about your cellphone. Military equipment is specifically hardened against EMP. And even if it weren't, a spare handheld GPS unit stored in an antistatic bag with a few batteries is all you need for a fix.
Reading a compass might seem trivial to you but for some young sailor fresh out of the academy that might not be trivial.
The compass is about the simplest interface around. There might well be the occasional person who can't figure it out, but most can, without trying. That's surely no reason to resort to celestial navigation training.
What happens if a software bug or a hardware problem occurs and says your 10 nautical miles west from where you really are?
Well, after your other two redundant systems flag the bad one, you just mark it for maintenance when you get back to shore.
still always good to check to make sure that your systems are running correctly.
That's great advice if there's absolutely no cost to the time and effort being wasted. Otherwise, it's pretty foolish.
It's pretty damn easy to check that GPS is working... Check that everything on the maps lines-up while you're in port. As you are sailing away, make sure there were no sudden jumps in your GPS fixes, particularly ones that don't match-up with the inertial tracking.
A guy looking up at the stars isn't really going to be that accurate, and it would be a soul-crushing job to work for week after week, to just keep coming up with the answer that: "Yep, the GPS is always accurate."
what if something happens to your ship and you have to abandon it
Then one of the people in the raft pulls the GPS unit out of the supplies bag, or his pocket...
Your scenario is insane... No GPS, but somehow the one trained navigator on the ship got into your life-raft, and remembered to bring a local map and his sextant along? Those silly myths should be dismissed, not encouraged.
You would want to know how to locate where you are so you could paddle the raft in the right direction
Accurate navigation is only important when you want to hit a tiny target... That's not happening in a life-raft. Generally you float aimlessly until someone rescues you, or you wash-up ashore. If you're damn lucky you'll realize there's a continent just a short distance to the north/south/east/west of you, and head in that general direction. You'll consume twice as much food and water in the effort to paddle somewhere. You'll make no headway against the wind and currents, or else will add barely any more speed. It will consume time better spent trying to fish. And if you're not very close to land, you simply can't make it before your supplies run out anyhow.
None of those sources claim Clinton emailed one piece of information that was classified AT THE TIME. It's idiotic to try and make an issue out of documents that were only later redacted. None of those sources show Clinton lied about one single thing. And the fact that "10 or so emails" disappeared isnt remotely comparable to the millions of emails the RNC conveniently lost, isnt illegal, nor does it show any willful act of deciept. So as I said, still no evidence she broke a single law, while Bush did.
It's about control, not security. Her and her administration should be tried for that first.
That seems pretty hypocritical. Hillary wasn't breaking any laws by using a private e-mail account. Meanwhile George W. Bush (as President) was undeniably breaking the Presidential Records Act law (which doesn't apply to Secretaries of State) when he similarly used a private e-mail server set up by the Republican National Committee (RNC). Yet neither he nor anyone else was held to account for it...
It never even got the tiniest fraction of the press exposure that Hillary has. No question the Republicans are better at spinning non-issues into big press coverage, and the Democrats are awful at doing the same, or even defending themselves.
Not really... You can always sign up for a cheaper provider that allows roaming onto Verizon's network. But personally, I'd try carrying a portable signal booster and see if that improves the signal enough for another carrier to function in those areas.
IPMI 2.0 includes serial over LAN, but that's text only console redirection. If you want graphical console redirection, you need to use a proprietary tool from your vendor,
I... don't. Why would I? Both Linux and Windows (since 2003 with EMS) lets you do any system fixing & reconfiguration you could want, via serial console.
With OoBM, you really only need to get your system booting again, and network reconfigured and working. After that, you connect via in-band management, whether that's SSH, RDP, NX, VNC, etc. It's stupid, wrong, and terribly inefficient to use your OoBM for all your system management.
If you're running graphical Linux, you need graphical console redirection
Bullshit. You mean if you don't have a clue how to manage the basics on a Linux system without the GUI, THEN you're in trouble if you don't have graphical console redirection.
You get power on, off, cycle, read the (hardware) system event log, configure the network settings of the BMC, and console redirection to a serial port. For Dell, you also have to enable redirection via COM2 in the BIOS if you want serial over LAN.
As I said before, IPMI also enables you to change BIOS settings. You can "enable redirection via COM2 in the BIOS" directly & remotely via IPMI, without ever entering the BIOS. It's a simple one-liner. Then you
The "redirection" isn't even really needed, except for seeing BIOS messages on boot-up. Otherwise you just need to tell your OS to enable a console on serial, and you're fine.

Except it also costs more to operate than the B-1:
http://cdn.theatlantic.com/sta...
Completely wrong. The B-1 is actually LESS EXPENSIVE to operate than the B-52, while possessing greater capacity:
http://cdn.theatlantic.com/sta...
We've already got two bombers vastly more advanced than the B-52, both specifically designed to easily nuke Russia. First the (supersonic) B-1B from the 1980s, and also the (stealth) B-2 from the 1990s. But they just keep using those old dammed B-52s everywhere...
If anyone has a dammed good reason those two are pieces of crap, and a new bomber is necessary, I'd love to hear it.
