I couldn't find a better map, but fluoride can always be found in meaningful amounts naturally in groundwater.

I use a RO filter, you insensitive clod! I don't even care what's in my water, unless it's so severe I can't bathe in it. And I use a spin-down filter, a spun filter, and a carbon filter before that happens anyway.

It's sad that you need to filter your municipal drinking water before you can drink it, though, especially when that's in part because they added nasty crap to it.

As to your used battery idea, it is not a good one. Most used batteries are car batteries.

Aside from the fact that we're talking about used EV batteries, it might interest you to know that high-end vehicles are now replacing their flooded lead-acid starter batteries with Li-Ion packs. Even a really dinky one is capable of starting the vehicle, but the truth is that there's embarrassingly more electrical accessories in the modern car, and they need a battery with more capacity so that you can use them all at once even in a vehicle with a stop-start system. As the price on electrically-operated accessories (like power steering, heat pumps, and so on) comes down due to economies of scale, you can expect this trend to proliferate down to cheaper cars. It's pretty hilarious to look even into older vehicles, say a saturn, and compare the size of the battery to the size of the engine. Which block is bigger, the battery box or the cylinder block? A Li-Ion battery would be half the size, and let you design a foot off the length of the vehicle — or put it someplace else, where it would do you more good.

Anyway, these Li-Ion packs can be broken down and their individual cells tested, matched, and re-used, so the car starter battery of the future will also be useful for these systems... just not the batteries of today. Those are already aggressively recycled, however, like most car parts.

Comment How does that argument play versus Linux? (Score 1) 218

CustomerP are generally too cash poor to be good customers. They are going to nickel and dime you for any project that you do for them because they are either too cheap to invest in newer technology or too poor to do so.

Latest statistics indicate that Internet Explorer has less then 15-20% of market share, with versions older then IE 10 being just 2.5% of the market. Looks like IE 6 is under 1% now.

It was similar arguments that massively hampered the adoption of Linux, Netscape/Firefox, .... Too few users, too cheap, expecting too much frree stuff. No money to spend.

It's one of the reasons general adoption took - and is still taking - so long.

It's also one of the reasons that companies that DID support them ended up with an edge on their competition, becoming some of the big-name companies in their markets.

Becoming market-dominant and ubiquitus includes not dropping substantial chunks of customers because you perceive them as "marginal". If you support 90+ percent of the market and your competition supports 70%, you keep getting little extra advantages. The outcome of competition is driven by tiny margins.

I've also used a slightly amount of hyperbole, they won't cost $0. Packs will at minimum have to be tested and recertified, and in many cases will need cells replaced — and individual cells will need to be tested and matched into groups of cells with similar characteristics for maximum output. That all costs some money. However, it costs nowhere near as much as putting the packs together in the first place; it costs some charge and discharge cycles, but there's no reason why these cycles can't be performed as part of an actual operating load-smoothing plant. After all, you'll have many modules in parallel, and any which cause you problems will simply be removed from the system. On the other hand, some packs might well be usable without any cell replacement, and they really would cost only the transportation costs and testing logistics and overhead, less the profit from their participation in load balancing during testing.

Those who are more paranoid acknowledge that ownership problem and do updates using an alternate method, i.e. login.

I don't think you understand what I said. If you've only got one uid, then both your web user and your shell user are the same user. This is typical of low-cost hosting services. Unless you're colocating, you've typically only got one uid. This ain't the law, some providers will let you crank them out, especially if you're chroot'd.

There was a study posted on Slashdot about this myth a few years ago. They concluded that Americans care more about their teeth because good dental care is expensive and so is a status symbol. Having few teeth is one of the stereotypes of poor/stupid people in the US. Middle class and aspiring middle class people in the US spend money on their teeth (cosmetically, at least) because if they don't then they look poor. For people in the UK, anyone can afford good dental care (for a while, it was easier for very poor people to because a lot of dentists weren't taking new NHS customers except under duress and people on certain forms of income support had guaranteed treatment), so going to the dentist is just seen as a chore and often slipped down priorities.

Yay for you. You were so smart reading, writing, and doing long division at kindergarten age. If only everyone else was so brilliant.

I was slightly ahead for arithmetic (but not by much), but I was at the very bottom for writing - to the extent that I was the only one having to stay in at break times for extra practice. This was not at a selective school (I started at one aged 7), this was at a school with a full mix of ability.

Its not natural or obvious how to use the three seashells. School is there to teach that.

That's rather my point. My school managed to teach all of us those things, what's wrong with schools in the USA?

Handling of the HYDROFLUOROSILICIC ACID is difficult. It eats through everything, even glass eventually. Tanks need replacement regularly, you have to wear hazmat suits when working around it... Go ahead get a little bit on you... it burns like hell and cant be neutralized.

This is the primary reason coupled with the fact that most kids have easy access to fluoride rinses and toothpaste. No reason to go with a preventative dones and scale back to a maintenance dosage.

Plus the crap is getting expensive to buy and truck. When I worked at a water filtration plant a semi truck load delivery was an expensive event, and that was 15 years ago. Today it's worse with the OMG WE ALL GONNA DIE OSHA standards for safety.

The hotel with only wired in the room.

I keep a tiny wireless access point in my suitcase for these cases. Even with ethernet on my laptop, my phone and tablet don't have an RJ-45 connector and I don't always want to be using my laptop as an AP. Most hotel networks can't come close to saturating 802.11g, let alone .n.
