Comment Not true. (Score 1) 153

There are airborne optical alternatives that can beat the * out of fiber - provided the weather is clear.

Fibre provides more frequency and better SNR than you'll get in the air, thus more bits

But a single fiber provides ONE PATH. Optics can provide MANY paths.

Imagine ten thousand fibers. Now imagine the ends poking out of a billboard in a 100x100 array - behind a 100x100 array of collimating lenses that beams the light toward your house. At your house imagine a telescope imaging that billboard onto a slide containing another 100x100 array of fiber ends. (Of course the fibers work both ways0 The air path may be of lower quality than physical fibers, but it's hard to beat a four orders of magnitude more paths. You'd need to run an actual bundle of hundreds or thousands of fibers from the billboard site to your house to beat it.
:
Now go back to the billboard and insert another 100x100 array of fibers through it - slightly offset so the same set of lenses but beams toward your next-door neighbor's house. (We'll assume the array is spaced out sufficiently that an optical telescope can resolve the two houses.) Repeat for ALL the houses served.

Not practical as described, of course. But it shows the principle: Wireless paths can multiplex spatially and reuse the bandwidth a hysterical number of times.

(Of course a real system using spatial multiplexing could be expected to use various wave-mechanical hacks rather than actual resolved paths - just as MIMO does down at radio frequencies.)

Sure, but: 1) they're making a lot less than if they were selling me both, and 2) a bare Internet connection is (at least hypothetically) replaceable. Once you've made the decision to drop TV programming, there's not a lot to holding you to a particular ISP.

Every time Comcast increases my bill, I drop a feature that costs the same amount. They're getting perilously close to the point where that feature will be "TV".

An open message to Comcast execs: be absolutely sure you're ready to make customers decide between your content and Netflix. I bet you'd be surprised how often the response won't be what you'd hope.

The point is that the relationship between sleep and the strength of the immune system has been well know and tested for years...

For a certain value of "well-known" and "tested". You could actually read the paper abstract and see what was novel about this particular study.

Knowing it in principle and knowing when to put that knowledge to work are two different things.

I used to catch *everything* that was going around, including some things most other people didn't. I got sick three, maybe four times a year. I always put it down to having a lousy immune system, until in one checkup I mentioned to my doctor that I'm a pretty loud snorer. "Better have you checked for sleep apnea," he said, and sure enough I had it, although only a relatively mild case. He prescribed sleeping on a CPAP machine, and since I've been doing that I almost never get sick. Maybe once in four years.

Anecdotal evidence, I know, but my point is this. Now that there's research demonstrating the impact of sleep on immune system performance it makes sense to make questions about sleep quantity and quality a routine part of health surveillance. I just happened to mention snoring to my doctor on one visit; if I'd been asked twenty years earlier it would have saved my employers a lot of sick time and me a lot of misery.

Comment Uncapped 4G is pretty nifty. However... (Score 1) 153

Uncapped 4G is pretty nifty. However... I had an uncapped 4G hotspot from one vendor, and it worked pretty great. Then Sprint bought them, and capped it. Then I had uncapped 4G from Clear. Sprint has bought them, and they start capping it, too, as of November 1st. I expect anyone who offers this service can expect to be purchased by Sprint (hey, built in exit strategy for your new startup!) so they can cap it, and charge metered rates for the inevitable overage (particularly now that Windows 10 does peer-to-peer sharing of Windows images and updates, and eats tons of upstream in the process).

If the city implements the infrastructure, then it's possible for it to be competitive, assuming the fiber bandwidth is either intentionally constrained, or effectively constrained by number of links into a single upstream at the head end (same thing that tends to make cable slow at "get up in the morning before work" and "people just got home from school/work" times.

A win-win game is not the only kind of non-zero-sum game there is. Suppose I set up a game in which the amount I win is 1/10 of what everyone else loses. I win $100; everyone else loses $1000. If I add up the net gains in the whole game, what we have as a net loss of $900 for all players. It's not fair; it's not reasonable for the community of players to favor such rules, but nonetheless I'm still up $100.

Broken windows may not be a net good thing for the community as a whole, but it certainly is a good thing for the glaziers.

I'll bet a lot of people love the fact that all this "free speech" will be taking place hundreds of miles out in the desert...

You don't know people very well then. As Lord Macaulay observed in his The History of England from the Accession of James the Second,

“The Puritans hated bear-baiting, not because it gave pain to the bear, but because it gave pleasure to the spectators.”

You see it is not enough for prigs and busybodies that they're not involved in any way in the things you do that give you pleasure; their problem is with you enjoying something they don't enjoy, or perhaps understand.

We are doing next to nothing. We are certainly not doing nearly what is necessary to prevent the problem. It's like bailing flood water with a drinking glass down the kitchen drain and saying you're "doing something" about the flood.

That list is clearly bogus. For example it lists Onagawa. The plant did shut down a couple times due to earthquakes but those shutdowns went by the book and so can't properly be considered nuclear incidents at all.

Of the ones that don't represent things going exactly as expected, or non nuclear incidents at a nuclear plant (a fire in an administrative building, REALLY?), most are industrial accidents that released no radiation into the environment (because the safety systems worked as designed).

For all the FUD, TMI released less radiation than a typical coal plant does in normal operation.
