Not true. A certain amount of control must be traded for stability in a system. Does Skype work? Yes. Would you run your business, 911, etc off of it? Of course not. At the end of the day, there's no accountibility.
Do you want to be able to dial someone with a phone number? A provider has to have control over that DID number (Direct In Dial) and be able to route it somewhere. Do you need to terminate a call off-network (non-VoIP)? A provider has to handle it.
If I have to choose between an open network where any shit flies, or a stable network that will work when I need it to and have people that I can contact to handle issues, I choose the later. I know that opinion isn't popular on Slashdot (where everyone should role their own software, where every bandwidth/phone/communications provider should provide their server for free, etc.) but that's the way it's going to be.
True. But until a critical mass is reached and a fair amount of users can have their calls passed phone to phone directly, termination costs are still going to be an issue.
Wifi generally cannot be used for voip at all. This isn't necessairly crippling, but a complete oversight of what consumers want. I have a wireless network at home, why can't my phone support using it instead of a per-minute rate when I'm here, or at work, or at the bookstore.
Soon phones will, but you'll still eat out of your monthly minute bucket. Why? Because even though you're not using a tower, you're still using the cell provider's central switching equipment to terminate the call somewhere. And if you're dialing outbound, the provider has to pay to terminate that call at a per minute/per second rate (depends greatly on contracts with termination providers).
Very possible. When a call comes down the line of a standard ILEC phone line, the voltage is ~100VAC to ring the ringers in the phones of your home. I don't believe most VoIP adapters support this sort of voltage on the phone side.
I'm glad someone said it. Ethanol is a TERRIBLE energy source when produced from corn, but when produced from switch grass it becomes a more viable solution.
Gallons of ethonol produced from an acre of corn: ~450 gallons
Gallons of ethanol produced from an acre of switch grass: ~2100 gallons
Ethanol use is acceptable because is completes the carbon cycle. Yes, it takes CO2 out of the air when produced. Yes, it releases CO2 back into the air when burned. When you burn a gallon of gas, CO2 is released, period.
Bandwidth is NOT cheap. I don't get how people keep pushing this myth. Even if you buy gobs of bandwidth from a provider (10GB/s+), you're still going to end up paying tens of thousands of dollars a month.
Call Cogent up and ask how much it is for a 10GB/sec connection. Even from a "cheap" provider such as them, you're going to be paying in the low five figures for monthly bandwidth. This doesn't take into account your edge equipment that you'll need to push that bandwidth.

Low Cost and Portable GPS Jammer
I built one based on this information for an electronics class a while back. It indeed works, as I can cause my Garmin III+ to lose positioning. Range limit is based on antenna used and power output.
While I know you're just using it as an example, it's not possible to retract the gear while on the ground in an aircraft. There's something called a squat switch on the landing gear supports that prevents the hydraulic system from lifting the gear when weight is applied to the gear.
Not to be cruel or anything, but from an economist's point of view, it would've been cheaper to ignore the marketing gimic devices and have something happen (in the event it was a "bad guy" doing something Terroristy(TM)) to that one person who decided to play with the thing then to send the entire city into panic.
Also, from a statistics point of view:
My chances of being killed by a terrorist on an airplane: 1 in 550,000
My chances of being killed on the way to the airport in a car wreck: 1 in 300~
While an ICE may not be the best way to extract work from an energy source, gasoline/diesel fuel still has a much higher energy density then alternatives. Batteries simply aren't there yet, and you're going to burn a ton of energy dragging low energy density fuels with you (be it in a plane or a car).
I'm a T-mobile customer. T-Mobile unlocked my phone for me at the store when I bought it. I would never leave unless their service went down the crapper, being a subscriber since the VoiceStream days (5+ years).
A great example of this is Battlestar Galactica from Sci-Fi. It has at least a 6 month lag time before it hits the UK from the States. Luckily for the Brits, people always throw up a high-quality rip on thepiratebay the day after the show airs. Now just think of the viewership (and corresponding ad revenue) if it was aired in both places at the same time (with localized ads of course).

Honestly, they should replace it without a hassle if it was showing physical signs of failure.
Excellent advice. OP should make sure to get documentation from the fire marshall/department and provide this to his/her insurance company.
Note: 10GB/sec should have been 10Gb/sec (as in Gigabit). I was in a rush.

I love that parody =) I find it just as witty today as I did when I was in High School.
Thanks for the info. I should've known better to go look at Wikipedia first.
Silly question. Why aren't there more root servers put into operation? (Honest question! I seriously don't know. Is it a technical limitation?)
Not all of the root servers may sit behind Cisco equipment

Dell outright butchers suppliers. There is indeed a difference. I suggest looking up both "symbiotic" and "parasitic" on Wikipedia.

Get back to reality people.
Or....we could simply perfect the conversion of cellulose into a liquid fuel, and skip the whole boilers issue.

Rioting takes time. Bittorrent takes less time =)
