While the truth is that the physical infrastructure is not free, bandwidth for setups like this can EASILY be free. Consider: What ISP doesn't want a good connection to the root nameservers? Answer: None. As such, they don't "charge" for the connections to connect it to their network. I seriously doubt that ANY isp is charging for the bandwidth to host any of the root nameservers. They may go so far as to pay for the circuits the bandwidth runs on too.
This would explain why I need so much sleep... I can never stop thinking about problems, and I have answers pop into my head each day for problems I thought I had been working the day before. Another tendency I have is (due to the number of problems I have to fight) I end up forgetting about some issue I couldn't solve before, a week later, somebody asks me about it, and I whip out an answer in a minute and have no idea how I came up with it.
From the last post dealing with this, I predicted the Shuttle was dead (http://slashdot.org/comments.pl?sid=92889&cid=798 0154) Now this gets canceled... What else is next?

While this suggestion is actually done in humor, I've been compiling a list of ideas to improve the current HTTP protocol, and such a suggestion (slightly modified) is actually worth looking at. Basically, it would be a "I'm returning an error because things have blown up here, please use any cached content even if it has expired" code, to allow caches to continue to serve "stale" content even if it otherwise have been purged.
On a side note, the company I work for has a product designed to help handle such surges in traffic, check out http://www.netscaler.com/
If you are broke, you can release the code to them under a dual license, like some libraries are, and have them pay a licensing fee. This could be the easiest way to make money off of open source--make something that everybody wants to steal, then bill them for it after it's too late. It's your code, you can release it under whatever license you want.
There are many issues involving ADD & ADHD (the H stands for Hyperactive) treatment. I was diagnosed with ADD at age 28, my wife at age 26.
From my experience, what I've found is:
a) People that don't have it or haven't lived with it generally don't understand it. You can have ADD and not be hyperactive, you just arn't able to concentrate (this is the category I fall into). ADD affects the way your mind prioritizes what it focuses on, and ends up not being able to focus on the "right" thing. This can be a blessing as well as a curse, as it can lead to creative thinking when you should for example, be paying the bills or working on homework. b) ADD affects adults as well as children. Most adults that have ADD tend to have learned coping strategies to deal with it like keeping notes on what needs to be done, etc. This doesn't solve the underlying problem though. As an example, I would have a hard time walking from one end of the house to another to do something without getting distracted, and forgetting about what I was doing. With proper medication, I can walk from one end of the house, notice something out of place that needs to be put where I was going, pick it up, get a phone call, answer it, and still get done what I was trying to do in the first place when all is said and done. c) ADD research is finding that it seems to be related to other neurological disorders such as narcolepsy and depression. Some of the newer medications found to help ADD were developed to fight Narcolepsy (Provigil). People with ADD tend to have depression and Alcoholism to a much higher degree than others, etc. Learning to understand the disorder instead of burying one's head in the sand is important. d) Not all ADD medications are stimulants, such as provigal and strattera. I personally take Adderall, and it works wonders for me. Care should be taken with Adderall though, as it is a stimulant. Users should NOT take it continuously, as the effects wear off, and if dependent on it, they will end up increasing their dosage on their own, feeling they need it, which happened to my wife. I, on the other hand, realized that I just needed to take a break from it, which I did on the weekends. My doctor perscribed both Provigil and Adderall, and I alternated between one another so that I didn't develop a tolerance to either one, yet had something to help me all the time as needed. e) Medication is just a tool. Using it can allow one to understand their behavior and help learn different ways of doing things. I use the analogy of a man who was born blind. If you tried to describe the beauty of a sunset, and what "orange" and "pink" were, he may think he understands, but still not fully grasp it. Give that man sight for a day, and he can understand what color is better. This is what many medications that affect the brain are like, when you find the right one, you can "see" how you are different, and use that knowledge to help adjust yourself to the world.
With concern to the original post, I can't see how using such a treatment could hurt, however, you may also want to see if your daughter can change treatments to gain better results. Below I've listed the primary webpages for the drugs I know about to help treat ADD. Since she is not old enough to understand this stuff herself, it is up to you to make the calls. I learned after I was an adult, and did the research on my own to find the right solution for myself.
Note also that ADD/ADHD is many times tied to depression and other problems. These will probably rear their head in the future, and expect that other issues may come up in the future.
Another thing--many people that I've talked too about this that have ADD have tried Adderall with provigil, and we all seem to agree on one thing: Taking both at low doses together seem to work better than either alone. My Dr. mentioned that other patients he had said the same thing. Check out this URL, as there is some interesting discussion on this topic and others related to it:
So in effect, everybody want's to keep you alive as long as:
premiums + deductable > cost of treatment
Once you get something where this isn't true, you can start thanking: a) being part of a group plan that protects you or; b) laws that keep you on a plan.
If you want to keep yourself safe, go to a supermarket that keeps their place clean, get some london broil or whatever is on sale (but looks fresh), and have them grind it up for you. While chances are some other meat will be in the meat grinder, that meat too came from a single piece of meat, and chances are, they didn't grind any cows brain there at the store. You are MUCH safer that way from catching anything from beef than if you take pre-packaged ground and processed meat. Most supermarkets will do this for free while you wait.
What was the point of the shuttle? To develop a reuseable space vehicle, right? Why? To cut costs. Did it? No. What it did do was place so many eggs in one basket there wern't any more eggs left. How did the last US astronaut get to the space station? By a Russian rocket.
The amount of money it costs to launch the space shuttle once, return it, and refurbish it for another launch is more than if we take the money to start designing a new heavy lifter that can reach the moon, but accept that it will be disposable. Maybe after we are done, we could have something as good as the Saturn 5 was.
I would be willing to bet that between now and 2010, there won't be more than 10 shuttle launches (I predict maybe two a year), and if anything, the shuttle fleet will be retired well before 2010 vs. their life being extended longer than 2010.
I believe that this push to the moon is because the shuttle is not even going to last till 2010-it will last till 2003, oh wait, it's already 2004! The shuttle is dead, this move is a politically sound way of justifying killing it off sooner rather then later.
With respect to the pigeons around the UK's nuclear waste processing plants, were you aware that natural Granite is ALSO radioactive to the point where under regulations it would have to be considered contaminated if brought onto a nuclear facility in the US? They don't use Granite in buiding such facilities so they don't have to deal with it.
Have you ever eaten food prepared on Granite? Will you now?
If you are worried about radiation levels, check a few of these links:
I went to this site right after the recent 6.5 and the site crawled. It better work well, because nothing slashdots that site better than a major earthquake.
That was the point. Create a win-win based on the desires of the user AND the business, and you can keep the customer happy AND keep from loosing money. It's the companies that can't figure out how to do both that will loose in the end.
Actually, before IPv4 became the "protocol for the Internet" there were no server load balancers. There were no dynamic routing protocols. There were no consumer or general business ISP's. As such, no, they didn't support IPv4.
Only ten years after IPv4 did many of these things really start becoming popular. There never has been a situation where one protocol replaces such a widespread protocol as IPv4 to my knowledge. Despite all the obvious flaws in FTP, and the fact that HTTP can be used for everything FTP does, people still think "FTP" when it comes to file transfer on the Internet.
There are several protocols that I don't expect to see replaced any time soon. HTTP-NG died on the vine, BGP-4 is still the primary internet routing protocol used between ISP's, despite many shortfalls, and FTP bites as a file transfer protocol, due to protocol behaviors that don't fit well into load balancing and firewall configurations. Telnet is used widely even though SSH is available for most functions, etc. People change to new technologies very slowly even when there is a compelling need to change to new technologies, simply due to the learning curve and time investements needed to make the change.
Your points are very valid however, and I've debated them often in thinking about IPv6, especially at what point companies should start looking to develop for it. The problem is that from a business perspective, not enough companies are willing to jump in, and unless they do, a criticial mass won't develop.
On the flip side, the fact that IPv6 is being deployed more widely in so called "catch-up" markets with large numbers of people will help push the protocol forward, but at what point will a website such as CNN be available on a pure IPv6 address? At what point will such a site be availabe ONLY on IPv6? Once the majority of the top 100 websites are available through pure IPv6 methods I will concede that the transition has happened, and everything else will topple to IPv6. Until then I will wait to be disproven.
In order for the general internet to function primarily off of IPv6 (and actually see the benefits), there are several things that would have to happen:
1. Most major firewall vendors would have to support it; 2. Load balancing vendors would have to support it; 3. Cache vendors would have to support it; Home-based router vendors would have to support it; 4. IT administrators would have to understand it (they barely understand IPv4, forget about IPv6; 5. Major co-location facilities would have to offer IPv6 support on the network connectivity; and 6. The majority of hardware and software running on network devices would have to be versions that support it (which isn't the same as that the vendors support it).
Fact: Most vendors of firewall products have only recentally announced support in their flagship products for IPv6 functionality. Only when the majority of users actually use versions that support IPv6 will there be critical mass.
Fact: most load balancing systems don't support IPv6.
Fact: Most routing products sold today for edge use don't support IPv6, and will probably never support it.
Fact: Consumer and even general business ISP's don't provide IPv6 support for connectivity.
IPv6 is akin to multicast Internet access: It is available in a few places, some networks can and do use it, some network hardware vendors support it, but as a mainstream technology that people everyday encounter, it will never be widespread (or won't happen in a LONG time). Predictions of it happening in this decade are way too optimistic, and if it does, then it could easily trigger a buying spree for network hardware that supports it of the like we have never seen, and network equipment stocks will probably explode through the roof. I don't feel this will happen though.
I used to run an ISP, and while it was dialup, we had a similar issue with customers staying online all the time. In this case the resource was the phone line and modem. We solved this by contacting those users and offering them a "dedicated" dialup at effectively our cost for the resources (came to something like $49 a month including the phone line, amortized equipment cost, etc). In exchange, we would also provide them with a dedicated IP and DNS name so that they could use the connection as they pleased. Most of the users had no problems with this, and they got something out of it themselves.
In a similar light, the cable ISP's could offer an alternative plan where they would cap the bandwidth used during peak times for "heavy" customers. Most bandwidth charges to such companies is based on the 95th percentile for bandwidth, so as long as you arn't helping push the bandwidth charge up for them, it's effectively free.
The real trick to this is that from a business perspective, they shouldn't care if you use lots of bandwidth during low use times, only if you cause additional expenses for them.
There are ways to enable a "gatekeeper" type function where requesting an ad generates a cookie for the referring site so that the site can determine if the ad was actually retrieved or not. This would allow sites to block browsers that don't at least retrieve the ad, thus preventing the "paid" access, where the fee is seeing the ad. As to if any of the ad services support this, I don't know.
I'm surprised being VT that they didn't just spec out their own motherboard and have an offshore firm build it. Companies like Google do this to save on the costs of components they don't need on a system. With a quantity 1K order, it would probably have saved quite a bit, but of course, there is always the time factor, which is one of the reasons why they didn't want to go with IBM.
