What would it look like once everyone starts broadcasting?
Very high frequencies have long been considered undesirable because they don't penetrate through or go very far around walls, trees & leaves, hills, curvature of the earth, etc. In fact they're greatly attenuated even by just the oxygen and light moisture in the atmosphere. Plus the millimeter wave band is extremely wide, leaving a big open space for everyone to fit-in without competing with each other. These features that makes them undesirable for one-way broadcasting of TV/radio and long-distance coverage, also makes them ideal for high-speed, short-range, two-way cellular communications, where people a mile away don't want or need to pick-up the signal at all.

Next question, which I didn't see answered in TFA -- is it going to be available not locked to Tracfone? Verizon is good here but my Verizon account is a lot cheaper than Tracfone.
Yes, probably locked for 1yr. HOWEVER, Tracfone has several services you can choose from. PagePlus is a VERY popular option right now, even among people not locked to Tracfone's network. Their $27/mo plan w/1GB looks pretty good, and you can go as low as $30/yr paygo plan for minimal usage, though $80/yr is a more practical minimum.

If your Verizon service is cheaper than that, they will probably NOT let you activate a smartphone on it.

There's no bigger fan of (full QWERTY) hardware keyboards than yours truly (see: #3NZG), but I absolutely HATE T9 (text on 9 keys) input. Back when I had a phone with T9 as the only option, I simply didn't send texts to anybody, nearly ever. T9 has given us all manner of ugly, unwieldy "txtslang" terms we're only slowly getting away from (like "smthg"), as input was so cumbersome that learning a new shorthand language was quicker than both parties writing messages in full and proper English. The most primitive on-screen keyboards are superior to that nightmare.

The physical keypad could still be quite useful. Android has lots of games, and mechanical buttons with tactile feedback would be far superior to control by touching nondescript regions on a smooth screen. Perhaps also for controlling apps such as music players.

I can't imagine an external device that would be able to work out the difference between desired and undesired signals from your phone.
You could make a tiny little $5 pocket signal detector with buzzer. When idle, you get only a brief little buzz every few minutes (or maybe entirely omit notifications for any transmissions that short). When a call is ongoing, or data is being transferred, buzz continually... That would raise the veil, giving people an idea of when their phone is sending data, and how much. If it starts going full-blast when your phone is sitting around in your pocket... a big red flag!

Of course you could do this pretty well in software, too. In fact the status bar icons show all cell/wifi xmit/recv activities on some few phone models.

Arizona is a sad case because libertarian fools run the state, and they refuse on principle to regulate and manage their natural resources sustainably, like adults.

California is a better model. Aquifers are recharged, usage restrictions are enacted, tiers are lowered, grey water is required for commercial landscaping, etc. Desalination is used to some extent as the technology gets cheaper, and tertiary treated sewage goes back into the water supply, creating a loop. Those last two offer a practically endless supply of water that can scale up to any population size.

Arizona could do all of this and would have ample water, but it's politically unpopular to talk about such things there, and they may need a harsh wake up call before the necessary reforms can be implemented.

But more importantly, even with that mismanagement, they're still doing infinitely less damage to infinitely fewer species than if people were developing old growth forests into cities and suburbs, or building just about anywhere else in the country, for that matter.

You have to keep in mind that there's almost NOWHERE with enough water. Forty out of fifty US states expect water shortages: http://pipedot.org/C373 . It's best to just accept that we can't stick a hose in the ground and pump enough water for everyone. Then we can move forward to practical management efforts, and it's doable everywhere, even the deserts. With California's jump-start on water management decades before anybody else was interested, I'm sure there are much wetter locales which will be hit much harder by droughts. Atlanta is one such example.

My preference is only to keep a house as minimally warm/cool as mechanical concerns allow... i.e. Heating is always set at 50F (10C) so that pipes don't freeze, and cooling is always set at 85F (30C) so that electronic equipment doesn't overheat (goes for pets, too). With that methodology, there's no benefit to even basic programmable thermostats.

I don't see the benefit in maintaining a temperature closer to 70F (21C) for human comfort, as it's necessary to dress appropriately for outside temperatures, anyhow. Going inside/outside repeatedly, with a huge temperature differential, is very uncomfortable. Instead such a "comfortable temperature" tends to just cause headaches, hot flashes, etc., and causes a more time-consuming burden of dressing/undressing when entering/exiting.

Now, if I had the opportunity to design my own home, I'd spec it with insulated pipes (among many other things) so that they wouldn't freeze even in very low interior temperatures. Then maybe I'd have incentives and a practical case study to find the lower limits of human comfort and this concept. But until that time, those high/low temperatures are the limits whether the building is occupied or not, eliminating the need for any changes throughout the day (or week).

I am sympathetic to the wife/girlfriend factor, as well as the need to manage humidity (condensation, mildew and mold) in some areas, and with some (usually, poorly-insulated) homes, but I can still usually make this concept work well-enough.

Similarly, incandesent efficiency was on a curve, so 60W bulbs had DOUBLE the lumens output of a 40W bulb. But with LEDs you really can scale that down as far as you want. No longer is a 40w bulb the lowest-power practical choice for smaller rooms, closets, etc.

The information likely comes from the companies wishing to sell their new products, and it appears they come up with the claim in part by somehow comparing LEDs to non-LPS street lights, which are really only used in a tiny fraction of circumstances, where more color accurate light is required. In addition, they seem to use more-focused optics in new LED streetlights to compare to unfocused LPS lights, and generate more desirable numbers that way. They often also tout how much energy can be saved by enabling a motion-detection mode, which LPS isn't suited to, but I'm not aware of any municipalities who have done so, as there are significant practical drawbacks.

The comparison can get a little bit more confusing because LPS lights dim a bit over their lifetime, so slightly weaker efficiency numbers can be determined if one is so inclined. But as for reliable sources, the best I've heard is that, with twice the longevity of LPS, the reduced maintenance costs of LEDs can make up for their higher up front costs.

But back to your question... I have no doubt many people believe that LED streetlights are more energy efficient than existing LPS lights. BUT I would certainly expect much better of civil engineers, and due diligence from even non technical personnel. They merely need to compare the listed specs like power consumption, between the various options, before recommending or approving a major purchase... But feel-good measures, and green-washing, are sadly all-too common.

There is no limit to "the shipping network". They can easily hire more employees, build more processing facilities, etc. You can easily see the interstates aren't so clogged with trucks that one more couldn't be added. And the decline of coal in the US has left railroads with plenty of new extra capacity they haven't been able to fill.

There's nothing new about that at all. "Flat rate" shipping has and always had quite a few strict restrictions on weights and sizes.

I'd also add that physically entering a residence to look through papers, leaves an obvious trail that is difficult to hide. Electronic devices don't leave obvious traces when someone, like the FBI, has decided to trespass, so it's infinitely easier to secretly surveil someone, possibly without court oversight.

Everyone knows the FBI is lying, bald-faced. They are perfectly capable of breaking into the terrorist's iPhone in question, but instead choose to use this opportunity to gain more legal authority to compel Apple, and other companies, to give them easy access they can use whenever and however they decide to do so. There is no way to prove to a piece of software whether you are authorized by a legitimate warrant, FISC, secret national security letter, etc., or not.

As I recently wrote on the old site:

The US was founded upon fear of an excessively powerful central government, as the British crown was seen massively abusing their power. So strong protections were built-in that weakened law enforcement for the benefit of civil liberties. There have always been other systems of government that are slightly more effective at catching or prosecuting criminals, but Americans knew, for hundreds of years, those trade-offs weren't worth it.

The limiting of government power was so ingrained that the US seems to be the only major nation without a state broadcaster. Outside the US, everybody in the world knows the VOA, but they are NOT allowed to operate inside the US at all. We believed the ability of the current government to directly influence the electorate, was too much power and control to give to our representatives, and settled on allowing only operation on foreign soil, with aggressive protections against even incidental domestic operation.

A warrant, today, gets the FBI exactly the same information it did 50 years ago... They can tap and record all the calls that occur after the warrant is issued, get a log of all previous calls that were made, etc.

Computers have made US law enforcement lazy. They expect they can get a warrant and will automatically be handed an archive with the contents of ALL of your communications for the past several YEARS. The information they got with a warrant decades ago is no longer good enough for them, and they're going to insist on the power they've gotten accustomed to, and refuse to allow privacy to make a comeback.

Remember, it was only a year ago that the entire contents of your phone were siphoned off by the police whenever you were pulled over just for speeding. This was done under the laws that allows them to look for weapons in the vicinity that you might be able to reach for, and which got extended to allow into evidence incriminating documents that just happened to be found in the process of searching for weapons.

And what did the police do with their gigabytes of all your personal information they siphoned off your phone? Maybe look for patterns of terrorism and drug dealing? No. Why they instead thought it would be a good idea to look for any nude photos you might have, and share them with their friends. Hooray for law enforcement keeping us all safe!

The San Bernardino case is pretty damn obviously worthless, too. The FBI has already FAILED to protect the public. The shooters already carried out their attacks, and were shot dead. FBI and Homeland Security failed miserably to identify them as threats, despite there being ample publicly available information to identify them as ISIL sympathizers. It's the same story as the 9/11 attacks all over again. Homeland Security had MORE INFORMATION than they were able to process and deal with, yet they use attacks as a lame excuse to expand their power, their budget, and get access to much more information, which again, they don't have any hope of being able to process in a timely manner.

Homeland Security has become better and better at revealing details after the fact, but is still useless at identifying individuals who pose a threat before they can carry out their plans to murder people. Apple unlocking iPhones for the FBI is more of the same... It won't possibly help identify future threats, it'll just be a little bit more information the FBI can publish about their past.

This was settled back in the early 90s with the PGP case. Code for encryption programs falls under the constitutional protections of freedom of speech. A new federal law or court ruling cannot override constitutional rights. Without the overwhelming support needed to pass a constitutional amendment (which nobody believes the US Fed can possibly hope to manage these days), they can't legally stop the export of software, including encryption, from the US.

This is the trick PGP used many years ago to get around export restrictions, and they were eventually successful in court:
Export Regulations only covers software in electronic form (e.g. on disks, or via the Internet). PGP 5.0i, on the other hand, was compiled from source code that was printed in a book (well, actually 12 books - over 6000 pages!). The books were exported from the USA in accordance with the US Export Regulations, and the pages were then scanned and OCRed to make the source available in electronic form.

This was not an easy task. More than 70 people from all over Europe worked for over 1000 hours to make the PGP 5.0i release possible. But it was worth it. PGP 5.0i was the first PGP version that is 100% legal to use outside the USA, because no source code was exported in electronic form.
http://www.pgpi.org/pgpi/project/scanning/
First amendment rights favor Apple on the opposite side of this issue, as well. The EFF supports Apple, on the basis that forcing Apple to cryptographically sign software for the FBI under court-order, is tantamount to the government compelling a person to say something, against their will.

It's a shame Homeland Security has gone so far the wrong way. Part of their purview is to help IMPROVE our domestic security against attack and interception by foreign governments. Under a cloud of public suspicion, the NSA improved DES back in the early days of encryption. They added trusted features to Linux and released SELinux to the public. etc. Now they're all about destroying what they used to build, as they have decided their own power to domestically spy is more important than the security of the nation against foreign adversaries. I suppose without a strong and looming existential threat from a nation-state like the USSR, we all too quickly forget our own disturbing history of government abuse, and lose our sense of priorities.

The fact the former CIA and NSA direct Michael Hayden is outspoken in his opposition to the FBI's request, should be a clear indication that the FBI is making our country less safe as they overstep their authority.

I placed 91 orders in 2015, 'mkay? I care a lot about 2 days vs 7 days. I use Prime Video all the time. So it is a huge bargain FOR ME.
Your numbers made me curious, so I checked on mine and Amazon reports I placed 123 orders in 2015, and that's a bit lower than the previous year. All this without paying a cent for Prime, and depending on free shipping.

Of course, without a dollar figure, this isn't too revealing... One $1 item can count as an order, and Amazon often splits up a single cart into multiple orders.

I will be curious to see how the increased threshold for free shipping affects their sales this year.

Walmart is closing stores and emphasizing online ordering these days.
Walmart is only closing 3 percent of its US locations... A tiny figure. And that's after a building boom, where they were putting new Walmarts EVERYWHERE. 66 percent of the store closures are their "smallest-format [convenience] stores called Walmart Express". Nearly all (95 percent) "of the stores set to be closed in the U.S. are within 10 miles of another Walmart." There are 4 Walmarts within just 12 miles of my location. And as I said, ordering online doesn't preclude picking up your online order in-store, for free. Not to mention the many other retailers with lower free-shipping thresholds.

$50 happens to be the cutoff for Walmart online, too.
Walmart also offers free $0 in-store pickup on ALMOST anything you can order online. No such option with Amazon.

Target is just $25 for free shipping. Sears/Kmart is at $35. Frys.com is still $34 to get free shipping.

Of course many 3rd party sellers listed on Amazon have free shipping included in the price, with no minimum order size, but Amazon commonly sells the item much cheaper, if they have it available at all.
