Keeping accurate time is HARD. Distributing it by the power grid is EASY.
Actually, time is not distributed via the power grid, only frequency. Time still has to be set manually.
The better system for distributing TIME is GPS. GPS provides both a highly stable frequency and highly precise UTC timestamp.
That's why GPS is generally what is used to sync up the power grid in the first place, although I imagine they have some expensive holdover and standalone cesium clocks as well.
But, it can't search any of those files.
It has a search function, but it's almost completely useless. I can even put the exact file name I'm looking for and it won't even be in the top 10 results.
The only advantage Sharepoint has over a simple shared file directory is some crude revision control and the ability to create calendars.
I don't think 22nm tech is going to decrease the cost of fabry-perot lasers or avalanche photo diodes used to make the high end fiber-optics.
These things have been in use for a long time in telecom and they are still pretty expensive.
If you're using multi-mode fiber in a small LAN then you can use cheaper components, but multimode fiber won't be as future proof if they ever move up to the terabit speeds mentioned by tfa.
But, in a world where math and logic are patentable every piece of software is violating some patent troll war chest. Closed source at least makes it more difficult for the patent troll to prove in court.
Actually I work in the telecom industry and most of it is actually highly competitive.
Circuits are a commodity and there are several competitive local exchange carriers competing with any given incumbent in any given area.
It's the last mile stuff that's really crooked. Wireless and cable/DSL have much higher margins and much lower quality. I attribute a lot of this to consumer ignorance. Someone shopping for an OC3 or carrier ethernet circuit generally knows what they are looking for and shops around. Somebody looking for an iPhone (or 'one of them new google iPhones') generally doesn't know their ass from a hole in the ground so they get shafted.
When people are willing to be shafted by the millions you get companies like Verizon and AT&T who arent really interested in the minority that knows what they want.
The problem with that is that most lasers are 0 Gillettes.
Possibly a better empirical measurement would be how quickly the feds show up if you point one at an airplane.
They've got some servers co-located at the data-center where I work
I don't work for that business unit so I don't know much about it, except that I once got a misdirected phone call from them asking to have an unresponsive server power cycled.
It wouldn't be too expensive to have a few terabytes in every town over 50k people in the U.S if you just cram them into a few RU of space at inexpensive hosting companies.
You generally don't need untrained crews to find a break. You use an Optical Time-Domain Reflectometer to identify the location of the cut within a few hundred feet, and then you send out your splicing and underground/aerial crews.
Upon arrival to a site the crew will either find an abandoned construction site or vehicle accident. Construction crews generally leave the site when they hit a cable because they know work is done for the day and their employer is about to have an unpleasant phone call from someone like me. The bill for a cut like this runs in the tens of thousands of dollars.
If an obvious break isn't found, then you have to start looking for squirrel chews on aerial and rat chews in underground conduit. That's generally just a partial break so you can roll your fiber at the two nearest splice points onto good dark fibers, or at least fibers occupied by lower speed systems.
No I can't. There's no oxygen in the bottle. I can see people being burned by spraying too much out and creating a fireball, but I'm having trouble envisioning a scenario in which the bottle explodes without already having been on fire long enough to melt through the plastic.
GPS is the most widely used synchronization source for synchronous optical networking.
There are two considerations here that many people don't realize are separate.
Frequency
Time
GPS provides Stratum 1 level clock.
Time is usually done via NTP and then kept accurate by your stratum 1 frequency clock.
Also, the position of the satellite is meaningless for issues of timing, it only affects geolocation.
It has amongst educated consumers i.e. server admins, researchers, and the top500.
Also, the Android platform is based on Java running on Linux. Where were the wince phones on this list again?
There are some great creative minds who happen to use drugs, but if you don't have an imagination without using drugs, then you don't have an imagination full stop.
I'm not an anti-drug crusader, but no matter what you think it won't make you interesting.
This is already happening. I know of at least one company that is building out fiber networks in semi-rural towns of a few thousand using federal loans under rural development programs. Those rural towns have better service than I do, now. http://www.usda.gov/rus/telecom/broadband.htm is the program they are working with, I believe.
The only surprise to me was that he punked out and didn't call anyone on the "We're segregated from men for our own protection." bullshit.
There was so much horseshit and whitewashing of the lack of equality it almost felt like I was watching a documentary on the Separate but Equal doctrine in the 50s.
I'd rather go to Cleveland on vacation than Saudi Arabia.
I've literally been pointed at McDonalds before whilst doing this.
It's pretty hit and miss depending on who you end up asking but online reviews generally point me in the right direction. Everywhere I've been the good places have good reviews, the bad ones have bad reviews, and the astro-turfing is childishly easy to spot because it'll be the only good review on the page.
Once you lose enough signal that you can no longer decode the digital data, your video becomes instantly unwatchable.
While we're nitpicking, this isn't necessarily true. There is such a thing as Bit Error Rate and you can have some in a digital signal and still have a usable signal. It might not even be noticeable. If a 24 bit color is off by the least significant bit for one frame on one pixel would you see it? It's an oversimplified example really, but I hope you get my point. On the other hand, a little bit of nasty on an OC192 can drop every cell call in 100 miles.

I hope they bring back SG:U as well, but the experts say that it will take 3 years, minimum. That is if nothing goes wrong.

That's 80 dBm.

Yeah, and it keeps the phlogiston from running to one side of the train and causing it to combust.

You can imagine the rest.

Precision is not accuracy. What are you doing on Slashdot?
If they experimented with latin cuisine would modern personal computers be the result of tacos?
I think that there is a flaw in your logic.

But not literally opposite, since they don't seem to oppose Big Brother itself.
