Actually, this is no contract service. The contract is for a subsidized phone. Unlike, say, Verizon, where you might pay $128 for breaking your contract--ever. Didn't get a subsidized phone? LOL cancellation fee.
I suspect T-Mobile is financing your phone, and rolling it into the bill. Haven't looked, as I don't have a contract.
What are you bitching about? Free Internet service for 15 years, and free completion of the failing and overbudget project that you were paying for. Now you just have to pay down the costs committed to already, not the growing behemoth and continued maintenance costs for the next 15 years.
I'm more amused that they're wasting time on Scratch. Scratch is a joke; the concept's been done. There have been games that targeted kids (back in the 5 1/4 inch days) which relied on "dialogue" that was free-form... in the form of little boxes with pictures, emoticons, etc. Essentially it worked because it was a valid, restricted, easily interpreted lexicon--a programming language. This comes up every once in a while, occasionally gets hailed as an amazing way to teach kids programming, which goes into "if we teach kids programming, Utopia!", which never happens.
That's what I get for making stale arguments from shit I haven't thought about in a while, I guess. It made sense at one point, but that was back when I knew what a halide was.
Also, This is not NaF, though NaF is harmless. Mostly I've never seen NaF actually used. Ca+ is a common ion in water so I guess this makes sense but I've no time to re-research this again.
Wikipedia disagrees with your analysis of fluorosilicic acid.
The Fluoride argument is like the Stem Cell argument. Stem Cell proponents shout "STEM CELLS STEM CELLS! LOOK, SO MUCH POTENTIAL, LOOK HOW MANY TREATMENTS HAVE SUCCEEDED!"... and you look and they're all Adult Stem Cell treatments, while people are arguing over killing babies.
Fluoride in ground water comes from fluoride crystal deposits--it's F+ ion. Fluoridated water has F+ ion as well, IIRC... I may be wrong there. The way it gets there, however, is by adding either a fluoride salt (NaF) or complex fluorochemicals, some of which are actually acids. This is toxic industrial waste with hazmat handling restrictions.
Yeah, you want fluoride in your water. You want it in trace amounts, though; and you want F+ ion, not all the other garbage that gets dumped in your water to get F+ ion into it artificially. If they artificially produced F+ ion by stripping it out of toxic waste, you'd get something vastly different--and the argument would be entirely stupid. Instead, the argument is between people shouting "FLUORIDE" while the reality is between Fluoride and Toxic Fluoride Compounds.
Yeah, this isn't a problem in America. In other countries, businesses will jockey around the law and do things like this. In America, they change the law first to make it legal, or at least make them legally not culpable (i.e. move the burden of verifying legitimacy on the recipient of debt collection notices).
The "Sleep" mode is an optional, non-default mode for preserving range. It activates when it's been configured, so that you don't lose 16 miles of range per day.
I dunno. Research says Tesla took many, MANY steps to prevent this, including advanced management systems that go as far as alerting the user. The car may discharge its battery completely if left in storage for a year; Nissan claims this isn't possible in the Leaf because of "an advanced battery management system that never lets the pack fully discharge, even when left in storage", so apparently Nissan solved the problem by trickle-charging the battery from a ZPM or Tony Stark's heart.
Yes, they found it to be acceptable. You come home and keep your car plugged in, it stays at 80% charge, an 8% drain is not a problem. You throw in a 30A breaker and hook up the 10kW charging station and plug your car in. That was the use case. The use case for the Model S is not "refuel at the end of the week" because it takes 8 hours to refuel and if you suddenly need your car it's got 50 miles on it and you need to go 75.
It made sense in that configuration to drain the battery. I'm pretty sure the Tesla Model S has both overvoltage and undervoltage circuitry--it won't charge above 80% unless specifically instructed, at least. The battery is also warranted up to 100,000 miles or 8 years and should retain 80% or more capacity after that--that's 500 charge-discharge cycles.
Tesla now has a sleep mode, because prior firmware was fast-boot and would sit in a wait state eating 8% battery per day. You'd be surprised at the resistance of a 100 foot extension cord of fairly narrow gauge; it doesn't take much to completely stop 120V.
"As cheap as paint" doesn't mean it is paint. Why are there so many flaming dumbasses here assuming this must be paintable solar cells because it compares the cost to the cost of paint? I can compare the cost of a loaf of bread to a blowjob from a $2 hooker, maybe the bread will give me a blowjob?
Lifespan, conversion-per-area, disposal costs (environmental impact etc). Wal-Mart generation likes cheap dollar price and prefers to throw away 10 things that cost $10 each than pay $50 for one thing that lasts 10 times as long, because $50 is a lot of money. Never mind the maintenance costs to replace stuff, the inefficiency, etc. I mean if they're 10% conversion rate, you need three times as much land as using a Sterling engine and parabolic reflector if you want a power generation facility--that's not cheap and impact is high, plus the more expensive engine-and-dish apparatuses need cleaning and polishing rather than outright replacement all the time (they're metal, teflon bearing rather than oil in the engine, and they'll last hundreds of years). Cheap panels on your house will provide less ROI and, while they may pay for themselves quicker, the ROI may be too low to justify the effort.
Modern laptops and top-end cell phones from Samsung, LG, and Motorola do this. Plug in your phone, pick it up, and start talking. It gets really hot. It also stays properly charged. It doesn't tell you it's 100% charged when really it's shut the charger off and is currently 80% charged. Note that the ideal charge under this condition is 70% or below--note that the Tesla won't charge the battery above 80% unless instructed.
Ideally the device would just shut off the charger and keep it below 80%. That doesn't actually happen. Worse still, even if your device keeps itself at 80% or below and calls that 100%, if it's continuously charging the battery while in use (i.e. if you don't get off the phone and find yourself at 80% reported battery life), the battery is experiencing degradation from being charged/kept charged while being used, thus being hot. The same occurs using a plugged-in $5000 laptop that's experiencing drain, even if it's cycling 10% of the charge or trickle-charging. Hint: Laptops trickle-charge, they don't charge cycle.
In the real world, any decent device will degrade the battery rapidly if put under load while plugged into the charger. Trufax. To avoid this, devices must keep the charge under 80%, and ideally allow for cycling down and back up over a wide range. Most ideally, you don't want to charge the battery when it's being drained heavily and is hot; but long-term use cases make this impossible in some situations (especially laptops; notably cell phones could dodge this by only charging when not in call or high data usage). Real devices provide the user with a guarantee that when they unplug and go they won't be at 50% of battery capacity; they don't provide the guarantee that the battery won't lose 50% capacity from being abused, just that it'll be topped at whatever its capacity is.
Actually what I said is if you shut off a cell, you no longer have the correct battery and shit doesn't work. You'd have to make the electronics work with it too, which requires more complex power supplies. Not impossible, but switching like that does have a cost and the battery life would be shorter to start with.
Each cell supplies a certain amount of voltage. Lead-acid, carbon-zinc, and alkaline batteries supply 1.5V per cell. Remove a cell and the voltage potential drops, which plays hell with electronics not ready for that big of a fluctuation. For example, when a car battery loses a single cell, it usually can't start the engine--it definitely can't when it's cold. Sensitive electronics may have some very odd issues with different input voltages. It's possible to compensate--worksite CD players run on 12.5-24V battery packs (as in the same exact model has ports for any of these and will compensate with fancy integrated circuitry). Usually computer equipment is prepared for this over a 5% deviation.
The real question is: is the effect real? NiCd and NiMH batteries don't actually have a memory effect; that's not a real thing, it's just folklore.
NiCd batteries, for example, experience a memory effect if discharged to the same exact level +/- 3% repeatedly MANY times, where the output voltage is not below roughly 1.0V, and the maximum charge is below or exactly 100%. If the batteries are charged with full overcharge or the level of discharge between charges varies by more than 3% or goes below 1.0V, memory doesn't happen at all in any way. Laboratory conditions. Essentially, a memory effect on a NiCd isn't a real thing; you'll never get there without sensitive metering equipment and very deliberate action.
No, in East Asian countries they don't function like that. They have school, which works well; they don't have parents "oh we have to ENGAGE the child, it must be made to DEVELOP!" The child is not in school, the child is helping with the cooking or some other shit, or playing with other children. Here in America it's "there must be extracurriculars, there must be educational games and television, we must buy our children toys that stimulate them!" A whole lot of "pile in everything that looks good" instead of having an actual, viable system.
Teenagers don't agree with adults because, basically, adults are wrong and teenagers are able to recognize that. Adults are wrong about everything. Look out your window once in a while. The problem is teenagers (and folks in general) don't know what exactly *is* wrong, they just know the people around them are old and stupid.
These are the people that grew up realizing that prohibition is wrong, while the adults were saying "NEVER DRINK ALCOHOL! NEVER DRINK ALCOHOL! NEVER DRINK ALCOHOL!" In school we didn't get the "Don't drink too much, don't drive when drunk" talk; we got "Drunk driving kills people and ALCOHOL CAUSES CANCER, DON'T DRINK ALCOHOL, IT WILL BRAIN DAMAGE YOU!" We got that talk, a lot. Result? Teenargers realize these people are stupid, somehow. Then, they go and do equally stupid shit like steal beer and guzzle tons of it off the keg. Underage drinking isn't a bad thing... if we're talking like a beer once in a while, at dinner, or something. A normal beer, not 12% shit that's really good but really fucking high in alcohol. It happens to be illegal because, well, the people in charge are stupid; the underage drinkers of course are also stupid and guzzle tons of liquor until they puke or die of alcohol poisoning.
I'm currently living in a cubicle, which is roughly high school. Everyone's about 20s-30s, about the same maturity level (I think the slightly older ones are less mature on average, but in general it's pretty flat), and doing roughly the same job. We're diversified now, but in high school we had the same thing--everyone got together and some people laid floors, some people ran framing, some people ran electric and HVAC--the HVAC and the electric folks were completely separate skillsets from the general construction kids, too. Then they'd stick them up on blocks and have them hauled away and planted somewhere, complete prefab houses. Shit the average 10th grader gets done in about 2 months.
Americans are too concerned with "mental development." Is this good for baby? Will this make baby smart? In every other country, they all have different parenting techniques; but the one constant is they all just bring the baby with them. The child goes with the parents, that is development. In America, development is boy scouts, summer reading programs, piano class, forcing higher math on a 6 year old, increased art education, science programs, "educational television", etc. So silly. What do you intend to accomplish by having kids socialize not with their peers and future social group and coworkers and bosses, but with adults who will be retired later?

It's also artificially limited to 15 days of usefulness; extremely fragile otherwise; and looks like an IED. Economic waste. Broken window.
