My hometown has municipal broadband, it's had it since 2000.

Your ideas are intriguing to me and I wish to subscribe to your postcards.

When I finally moved back a few months ago, the technicians who set me up kept raving about how awesome it is to work for my town's municipal broadband. We have municipal electricity, TV, and phone too!

"spazzies"? Really? You know, before the car accident that screwed me up, I was perfectly normal. Now that they've done surgery to correct the issue, I'm perfectly normal, with a little extra titanium hardware. We're all one car accident away from having the same issues. That is, unless you never leave your mother's basement.

Ya.. There are are a bunch of whiny bitches here. :) The same ones who complain about kids, or the fact that I bypassed the lines in the courtesy wheelchair, because I couldn't walk through an airport.

Thanks. I am so delighted it got fixed. It only took about 1.5 years and a half dozen "expert" doctors to find one who knew what he was doing. I had sympathy for people who couldn't get around before. Now I have a *lot* more.

Only if you're lucky. Well, I think SW does that. No other airlines I fly do. I don't really care about kids. My ears have never really tolerated flying much, so I have to use the pressure relieving earplugs. Wearing noise cancelling headphones over them, I can barely tell the engines are running, much less screaming children. :)

No, you really want them to board first.

For the last year, up until last month, I was barely able to walk. I still had to fly for work. I boarded flights with the kids and anyone else that needed help.

The parent doesn't just stow their stuff and sit down. They stow the kids bags, get the kids to sit down, shut up, buckles on, no you can't go to the bathroom, blah, blah, blah.

For me, it took me about 4x as long just to get down the airway. A guy barely walking down the ramp with passengers walking normal speed definitely held up the flow, no matter how much room I tried to leave. I still got held up by the parents with kids, and I didn't care. I'd just sit on the nearest armrest until they were done.

You don't want me, or the parents with kids slowing you down. People are assholes enough boarding planes.

If you wait for them to board last, now you'll have parents trying to stow bags in the last few spots (if there are any), trying to get the kids in their seats at the same time, and having the kid(s) climbing over other passengers.

For me, barely able to walk, if I had to take the window seat, that would mean everyone in the other seat(s) would have to move. Walking on a cane, I wasn't able to just squeeze by anyone, especially if there were no good seats available. It was still hard just to get *to* the window seat.

And before any of you complain, since surgery I can walk fine. The cane is retired at least for another 30 years.

Syncplicity lets enterprises store files on their own servers, with an extra layer of authentication that prevents Syncplicity staff from getting to the files. It still allows for access to these files through a web browser. When enterprises use single-sign-on, users don't even realize that they're authenticating multiple times.

This is a very hard problem to solve for consumers, though. Most people don't have the time to set up their own cloud servers.

Level 3 Communications is (or at least was) a really great company to work with. When the company I worked for was a huge customer of theirs, they did anything and everything to satisfy us. The claim of them volunteering to install 10GE cards really does sound like something they'd just do to make a large customer happy.

I really miss working with them.

With electrolisis and a fuel cell, only the gas carried contaminates could possibly contaminate the drinking water. For quanity and qualityproduced, I'll take the solar solution. The distances traveled and the amount produced are both quite small. In the solar solution, the volume would be much greater and due to the recombining of gasses, much less likely to transport pathagens.

Charged particles are not magnetic. The electric current caused by the electric current creates a magnetic field. Basic electrical magnetic property. There is a magnetic field because there is an electric current traveling through the atmosphere which does impose an electric charge on suspended insulated objects in addition to the induced electric current in conductors on and in the ground.

The amount of induced current is directly related to the rate of flux change producing an AC current provided one end of the conductor is grounded. At the low currents and large area of very long lines, this AC component is relatively low in relation to the DC current brought in at the poles seperated by our earth's magnetic field. A static magnetic field does not induce a current. A steady DC current does build high currents in long suspended conductors.

http://en.wikipedia.org/wiki/E...

Even high voltage transmission lines are now protected by adding a resistor to the center tap of a 3 phase transformer to ground to limit induced current. The transformers already MUST have a ground refrence already due to the DC charging of the lines that would happen if there were no ground. This is why transmission lines never use Delta transformer to Delta transformer. One or both ends of a transmission line have a substation with a Y connection with the center tap grounded.

I know of one BPA line that is Delta to Delta, but in addition to this there is a 3 phase Y transformer to nowhere that only porvides the required ground for the line.

Grounding both ends with a low impedance ground is good for lightning strike protection, but bad in a geomagnetic storm. Ungrounded is bad for line charging and lightning protection. UTP network cable is ungrounded at both ends and are subject to high voltage charging in short lengths.

The elevated lines between buildings are rarely protected from a build up of a static charge as routers and bridges were not built with this in mind. On the physical layer, both ends of the wire are terminated into an isolation transformer with no discharge path to ground. This is an installation design fault against the guy that designed the installation. Lightning protection is often a gas discharge tube for a lower breakdown voltage. A high current discharge through a protection device can produce a relatively high ESD pulse through the transformer into the tranciever chip resulting in corrupt data to failures. A link between buildings must include a bleed discharge path to prevent the build up of voltage on the wire, or a shielded wire with grounded shield should be used.

Engineers design systems. A good technician can make them work.

Comment: Time to apply science (Score 4, Informative) 78

Time to apply science to the problem. What is known, what values are involved, and what breaks down.

Long distance transmission lines have two problems when there is a relatively high atmospheric current. They are long conductors feeding transformers that are not designed to shunt large components of DC resulting in core saturation and high current. This is measurable. The first effect noticed was by the railroad when telegraph relays activated and sometimes burned out.

The voltage induced current has two components. 1 Some current was due to the current directly into the long wire. 2 Some current was due to ground potential changing due to high current in the ground.

How to protect? For ground potential issues, simple pairs of wires provide high common mode rejection. This is common with telephone circuits as protection from induced hum and noise from a noisy electrical environment. Overvoltage protection in the form of lightning arresters is the second protection. Most phone loops are relatively short reducing the ground voltage gradient problem to non existant levels. Long distance hops are by Microwave Relay or Fiber Optic, both providing protection from ground gradients and long pick up paths.

Shrink the scale to inside a home by comparison. All internal house wireing is orders of magnatude shorter than transmission lines, CATV, and phone lines. Small DC capible antennas result in very low current if exposed. The home is generally protected by gutters on the eves, mildly conductive building materials such as wood, brick, etc that are not insulated to very low leakage at high voltages such as the insulatin on transmission lines. Net result is the very small currents are shunted by the building itself. Go up on the roof during a geo storm and see if you have any static electricity issues. Probably not.

For homeowners, this is a non issue due to the lack of an effective gathering surface properly insulated to collect enough current to cause any damage. The collector is too small and the leakage path to ground is too high.
