The FAA advisory says there is a 253nm ring of interference at 50ft AGL (above ground level)
So, depending likely on your line of sight to the transmitter, there is a good chance most of Southern California and Nevada are going to have ground-level interference.
My question is what will happen to the many datacenters with roof-mounted GPS antennas that feed to a local NTP server, which is trusted as a Stratum-1 source inside the company? Those antennas are very likely to be at 50ft AGL or above.
GPS is just a timestamp. If you're screwing with that, there is a good chance what you're doing is screwing with the time.
1. They want to learn more about what it would take to compromise the existing USA GPS, so they know how to detect such activity and perhaps test countermeasures.
2. They want to be able to compromise GLONASS and Galileo without compromising the SA GPS signal. However, in testing this, they might get it wrong and take down GPS.
I've seen this play out at a F500 company where I live that copied GE's mentality.
One team of all-stars took turns on the roulette wheel. It was something as arbitrary as alphabetical order: Top performer in Q1 was Adam, middle was Beth, Jerry, and Roger, and Sam was the lowest performer. In Q2, Sam was now the top performer, and Adam, Beth, and Jerry were now the middle, with Roger now the lowest performer.
Their boss explained it to them, objected to what the company was making him do and complained to his boss, but he had a team where all were awesome and didn't want to lose any of them.
Sure enough, one day a mandatory culling was announced, and a great employee was let go because it was her turn on the wheel.
Bonus: At this company, if you are ever let go because you were at the bottom, you can never be hired again.
I don't understand the delays. Just sell it HIGH right out of the gate. Make movies something crazy like $60-$80 on opening weekend. Grab all that extra profit while the hype is high and plenty of families with great home theater and 2.5 kids that they don't want to pay concessions for consider it a win-win. Drop it by $10 or so every month or so, until they're $20 at the same time they're available now. Why do they hate money so much?
I drive a car from the 60's. Will continue to do so for the rest of my life.
And I think you'll be able to do that, but you'll likely be banned from limited-access highways.
I'm ok with a few, but, how do you pass 50 or 100 of them in a solid group? Bicycle technology was surpassed 100 years ago, yet there they are.
You're going to have to just enjoy that 70-year old car as you cruse slowly behind them on the winding road you're on. If you wanted to get there faster, you'd be in an SDC and on the high-speed roads. Note that while bikes are still here, they're not allowed on many Interstate highways. So a partial ban does exist for them.
What are you going on about? Safe Internet? What's that?
I don't trust password-protected wireless any more than I trust open wireless, or my Comcast connection.
Anything I do over the Internet that needs any sort of security is going over AES-256 encryption. The encryption of wireless is only somewhat useful to make sure people don't use wireless they shouldn't have access to.
Companies do this crap all the time. If I were informed that I'd be training my replacement, I wouldn't do it. Buggers want to replace me, they can figure out what's going on for themselves.
Usually, this is done by the company responding with: "If you want to leave now, that's fine. However, if you complete your duties, including training, and remain for the next 3 months, you will receive a severance package equal to 1 month's pay for each year you've worked here" or something like that. There are a lot of 40+ year old people with 10-20 years in a company that are not confident they'll find a job in the next 10-20 months, and may not have 10-20 months of savings tucked away.
Honestly, I thought this was a very useful feature for small businesses that had wifi with a simple password.
I noticed quite a few friends had the same idea as me, because I would go into a new coffee shop and my laptop could connect right away because one of my friends already checked the wifi sense box.
Now, I know no one that did this on their home network. However, for networks like a coffee shop or hotel, it is great.
First, airports will close in bad weather. That means airplanes either have to wait for the airport to reopen or they will land elsewhere.
Airports closing in bad weather is rare for more than a few hours. We're usually talking about a single airport, and the delays are usually on the order of an hour or so. Sometimes 4-8 hours, but it's not that common.
However, a storm front moving across the plains would ground nearly every transcontinental zeppelin for a day or more.
Also, if we're just looking at airplanes, we're talking about around 500mph, not 80 mph. An airplane can suffer through a 2-hour delay and still beat the zeppelin, who is sitting on the ground waiting for the storm to stop. The jet just needs to see the runway a few hundred feet before landing.
Finally, trains are still chugging along at around 80mph and could easily be powered by "green" power by installing electric lines overhead, and they're not going to get stopped by weather. Even feet of snow can be pushed aside by a plow train.
I've had to explain this a few times to people that don't understand how it is cheaper and uses less fuel to go out of your way to stop in Alaska to refuel even when your airplane has the ability to fly from China to Tennessee without stopping.
It seems counter-intuitive that 2 flights with more miles is more fuel efficient until you realize how heavy a fully fueled jumbo cargo jet is, and how much fuel you burn just to carry fuel.
The issue with this is that I'm pretty sure NTP authentication is bidirectional by IP address. That means Apple would need a unique key for every iOS device, and they would somehow have to dynamically update their current IP.
NTP authentication is pretty broken IMHO. I wish it were something that was one-way, where the clients can just have a trusted signature installed and validate the timestamp. It isn't critical to hide the NTP info from snooping, just to validate that the timestamp has been issued by a trusted source and that it hasn't been modified.
In places with a lot of sun and solar panels like Hawaii, wouldn't there be more power during daylight hours?
It's hard to overstate the amount of power used during the day. Every office building of any size in Hawaii is likely using A/C, and shutting it down or using far less at night. Add to that any type of daytime industry, from restaurants to factories, and the hours that people are sleeping just can't even remotely compare. The peak seems to be around the time everyone gets home from work. Check out this page from Hawaii's electric company. See that big dip from around midnight to 6am? Charging time. If there are enough people charging during that time, the yellow base load rises and power becomes cheaper. Power that can be generated at a steady rate is cheaper than power on demand.
My office has a 55" 4k TV in it, got a good deal on it Black Friday and it has given me the chance to compare. My primary TV is a 70" Sony 1080p and my secondary TV is a 60" Sharp 1080p.
What is your viewing distance to these TVs?
Seeing a difference in 4k depends on screen size, distance from screen, and how good your eyes are.
It looks like the F35 is the perfect military industrial complex aircraft, forever requiring upgrades and bug fixes and not just from the US government from every government required to fork over 2% of GDP tribute payment to the US military industrial complex.
I'm not a fan of the F35 program, but this is still done in meatspace with aircraft as old as the B52.
The aircraft manufacturers are constantly pushing new hardware updates, new specs on how each bolt should be tightened, etc. Those don't come for free.
It is even possible that ongoing costs will be lower with something software-based rather than hardware. It turns out that way often.
I don't expect it to get cheaper, but if it doesn't it is in spite of software updates, not because of them.
Right now, as a small game dev, you could write for iPhone or Android. There are are reasons to do one or the other first, and maybe, just maybe, you'll write for Windows 10.
Now, if you write for Windows 10, your app is available on Windows 10 and Xbox One.
This isn't just a matter of store size, but which platform has the best chance of generating revenue. That is a function both of store market size and the tendency of people to actually buy stuff from the store.
Also, as a Windows 10 and Xbox One owner, I'm far more likely to spring for the $1-$10 for a little game if I know I can play on my laptop, and resume on my Xbox. The more people are willing to buy, the more that marketplace becomes more attractive to devs.
I recall some of those Kronos time card devices I used years ago would learn the default gateway address on their own without being provided a route. They didn't even have a place to put in the default gateway.
I have to assume these devices can find their way out, so I VLAN all IP cameras and don't allow them to access anything.
Disney can go and get fucked, and I for one (despite have a young family) intend to never give them a cent of my income for the rest of my life.
I'm not saying that it is impossible that you're doing this, but it seems highly improbable.
Their ownership of ESPN means that if you have almost any form of paid TV, you're paying Disney.
On top of that, owning the entire Marvel franchise, and Netflix's Marvel shows, means a Netflix subscription give a cut to Disney.
Hulu, owned by Disney.
Then the whole Star Wars franchise, which isn't just TV. Anything with Star Wars stamped on it, from a video game, toy, t-shirt or a coffee mug, gives some money to Disney.
Do you actually avoid all of these? Bully for you if so.
Nooo.... it must be some sort of weird, unexplainable conspiracy between Sony and the FAA or some shit.
Never said that. They just didn't give a shit about doing it, and then it became a whole sidebar debate about people on their cell phones during a flight which had nothing to do with the issue.
Or that there might be a slight difference between two tablets in the cockpit and 300 tablets & phones distributed through the entire length of the plane?
If EMI wasn't an issue 1 meter away from all of the avionics, it certainly wouldn't be an issue farther away. Learn about EM radiation and the inverse square law.

I see two possibilities, which may both be true:
1. They want to learn more about what it would take to compromise the existing USA GPS, so they know how to detect such activity and perhaps test countermeasures.
2. They want to be able to compromise GLONASS and Galileo without compromising the SA GPS signal. However, in testing this, they might get it wrong and take down GPS.

Yeah, I've heard of this, but it sounds about as appealing as UltraViolet.

Anything I do over the Internet that needs any sort of security is going over AES-256 encryption. The encryption of wireless is only somewhat useful to make sure people don't use wireless they shouldn't have access to.
The intent is that you need to go ask someone at the store what the wifi password is, or find it on a menu.
I agree, it is stupid, but it still exists, and the wifi sense feature made it less of a hassle.

You don't fly much, do you?
Quite a bit, actually.

That's incomparable.
People are a bit picky about planning travel in advance and getting places on-time.
There are usually thunderstorms daily in the USA, and buses, trains, cars and airplanes go right through that.
Zeppelins have to wait for the storm to pass.
Regardless of Hindenburg, their fate was already sealed.
Family of 4 on Comcast here.
We did 1.4TB in January, and 1.2TB in Feb.
667GB in March, but we went on vacation for 14 days.
We don't torrent. We don't have cable TV service, we use Netflix, Hulu, and Amazon Prime.
We may be the exception, but I see more families heading my direction rather than ours.
The point I was making is that not too long ago, DHL, FedEx, and UPS all did direct flights from China to the Midwest USA.
One of them (I think it was UPS) discovered the Alaska stop saved them money, and within a short amount of time, all 3 were doing it.
I don't think they'd be doing it if it cost more money. Sounds like even with all of the extra costs, the amount of fuel saved still makes up for it.
This is dead-on.

Nice! I've yet to see this implemented, but glad to see it is being worked out.

Ironically there's a film on that list called Firewall.
Which is less realistic than Edward Scissorhands, sadly.
