Comment Re:The problem of Microsoft (Score 1) 337

The problem with MS is that they have never been in the business of supported or selling to end users, and they are entering this market at the expense of the desktop business market.. The cost of their software products, at the consumer level, has always been very high end. They have lower priced products, but those tend to be so incomplete as to require a lot of time to make work. Remember, the product is only cheap if your time is worth nothing.

So MS Surface is a good product, but it is expensive for what it is. To make it look cheap they compare it to a 13" Macbook, but the reality is that if is priced evenly between a 11" and 13" Macbook, so is not aggressively priced.

For better or worse, the reason that consumers buy MS Windows based PCs is because they are aggressively priced. A laptop can be had for 1/2 the price of a Mac because the laptop can have lower specs because MS Windows can run well on lower spec machines. I am not going to run on an I5, but there are many who that is fine and they can get a cheaper laptop than Apple provides, and get service from a third party that caters to end users.

It is going to be a while before the culture shifts to MS being a seller of premium consumer product. This will happen, if MS is serious about being such a firm, but that opens up the business market. Already MS is talking about only supported one version of IE, which means that business is going to have the headache of rolling out frequent updates. Apple is teaming with IBM to get point of use applications on iPad, which will significantly reduce the cost of supplying business rule applications to worker bees. Firms can already create custom apps on Android devices to serve the same purpose. MS Surface should be a way to counter these losses on the desktop. Instead they are produces commercials to make the MS Surface seem fun, and charging extra for a keyboard.

Comment Re:No, school should not be year-round. (Score 1) 421

Summer breaks are useful for parents of means who can put their kids into other activities or parents with commercial activities with which the kids can help. For most everyone else it is beneficial to have year round 8-5 school, not because kids get more educated but because it is highly effective babysitting.

A case can be made for a trimester year round school situation in which students are required to attend two per year. Two in a row can be missed with permission, and missing three is equivalent to dropping out of school. This could be beneficial in many ways, but would be complex.

A big problem with the proposal is simply costs. Right now there is a lot of stuff that happens in the summer. Some of it is paid by school budgets, some of it is paid by external grants, some of it is paid by the teacher. The fantasy is that we can increase the school year with no significant costs. This is not true. Over the past 20 years teacher pay has gone up considerable, and a lot of that cost has to do with simple additional time the teacher is required to work. This is the same in any situation. If you are paid hourly, i.e. required to be at work at 7 and work until 3, if they ask to work until 4 every day then that should come with additional pay. This is what has happened with teacher, the additional few weeks and time per day has increased pay about 15%. If we go year round the pay will increase another 20% at least.

There will be other costs. Training will not happen during the off time, so staff will have to hired to cover classes. The argument cannot be made that personal business can be handled during breaks, so teacher will have to take days off during the year, a practice that many teachers now try to avoid. This again will require additional staff hire. To give you an idea of this additional cost, say a school has 60 teachers, which is a small school. Two weeks of training and two weeks of personal time is 20 days. For all teachers that is 1200 person-days, let round it up to 10,000 person-hours. At minimum wage, rounding up again, is $80,000 per school in class coverage costs. Not all of this is new costs, but it is significant. Add a half million for additional pay, weekend costs to maintain the school that is now down over break, and one is looking at a cost per student going from around $7,000 to around $8,000.

Like so many of these studies the centers of the data are of little use for someone trying to quantify speeds. Even if we had a range for the center, say a standard deviation, that would still leave out variables like size, population, geography and variables in population density. It is unreasonable to publish a single number for a states as meaningful. It does back to the idea that one can make a bunch of junk numbers seem more valid by putting them on a pretty map.

Comment Don't have to go back 100 years (Score 5, Insightful) 315

25 years ago there was desktop cold fusion. A lot of people wanted it, there were conferences on it, probably at least a hundred million was invested in it over a year or two. but it was bogus. The hypothesis was sound, it was no completely unreasonable, but the experiments showing a positive results on the hypothesis were flawed. It is not that cold fusion does not exist as something that might happen, it is that we have not shown it happens. I don't want to muddle the situation, but there is a clear line between what can happen and does happen in the lab. Theoretical people have told me that their models are necessarily not connected with reality. They are math, and the math sometimes tells us what is going on, sometimes fools us, and sometimes is just bonkers. What differentiates all this is good experimental science, which is really hard to do. I mean really hard, and for the most part does not lead to a theory, but only data that can be collected by math. This is why even though Galileo did a lot of good research, it was 100 years before the math caught up and we were able to do what we now classify as as science.It is why electromagnetic, the speed of light, quantum mechanics, and what is to follow is going to drop out the math. Which is to say we have a very complex interactions. Virtual particles drop out the math. The math says that they must exist, but inherently can't do anything useful. This is in the same way that photons can be coupled so they may seem to act faster than the speed of light(maybe, until we get distances longer than the earth-moon system we cannot really know) but no one expects information to be communicated faster than the speed of light. The end result is that if you have an experiment that violates the math, you have to be very sure it is a good experiment, and the consensus is quickly building that this is not. There is a certain responsibility to being an experimentalist. One can't just willy nilly say there are 40 dimensions of energy is created from the aether. On can be sloppy with conclusions, as Einstein was with the photoelectric effect, or Milikin in his oil drop experiment, but one does have a responsibility to do ones best to control systematic errors, and not jump to conclusions when one does not fully understand those errors. Unless, of course, like the two cited authors you are lucky enough to be accidentally correct.

Comment Re:WTF? (Score 1) 172

We also have to look at how repeatability works. One reads a paper, does one best to follow the work, perhaps calls one of the researchers to get clarification, combine this with known methods, and at the end of the day maybe get a similar result. If, as in the case of cold fusion, the result is not similar, then there is at least some carelessness if not fraud in the original result. Which is fine because it is just one result, and no one should thinks one result is conclusive.

In social sciences reproducibility is possible. For instance in epidemiology databases are crunched using well known statistical methods to determine correlations, then further science is applied to determine is these correlations might be causative. If a second party cannot do an equal statistical analysis and get similar results then the results are not valid. If a second party can go through the process of collecting the data and find systematic errors, then the results is not valid. This is in fact a big problem with education research. When subject to the process of real science, much if not most of the research has been shown to not meet those standards.

So social science research can be scientific, but there is a second issue. We expect research to be predictive. It is said that field such as astronomy are as unscientific as social science. But in astronomy there is an element of application. The results are used to predict other finding which then can be confirmed. This is the element that makes fields such as physiology less scientific.

Comment Re:Real world equivalent (Score 1) 171

I thought of it another way. You go to the store and everything the kids touches goes on your credit card. Remember, most of what occurs in the apps has no real world equivalent. You can't go and return it, or even complain it was faulty or did not meet expectation. At least a theme park if there is bug in the ice cream you might get another one.

In any case,Apple is absolutely wrong here. If this were a convenience feature it would be easy to add in a setting like they do with so many other features. For instance cellular data roaming can be turned off. To make sure that Apps still have an opportunity to waste bandwidth there is an annoying reminder to turn the cellular data back on when accidentally using the App. If Apple wanted go, it could allow users to set the time interval anywhere from zero to 15, or more, and then allow the App to be as annoying as it wanted to get you to turn back to 15. As it is, the protocol is clearly meant to maximize unintentional in App purchases.

Information implies past data and perfect information implies absolute security and verification. This is more possible through the medalian system as carry a large cost and can be removed if people are very unreliable or dangerous. Of course the system is not perfect, but utilizes the time tested method of excessive punishment for certain acts, as well as background checks. Look at it like cleaning staff in a hotel. They have oppotunity to steal, but there is likely no due process if an accusation arises so there is less incentive to steal.

In the current system, information may be collected, and may be reliable, but it is not verified or acted upon. One can imagine where a driver gets a bad review, then creates a new account with a friends credentials. One can imagine a case where cars are not well maintained and cause an accident.

In fact the solution to this is very simple and should not raise the prices much if the profits of the service are moderated. Require each driver to carry commercial insurance and have a commercial drivers license. My father had one, so I know they are not difficult to get. The service could contract with an insurance company to provide a customized package. I think it is important for each driver to contract with an insurance company, not the service, because the insurance company will have additional checks and verifications. The policy can then be linked to the profile to insure that a driver is more likely to be who he or she says it is.

Right now these services are simply trading security for costs. For some this is a good tradeoff. But if the system of regulated cabs is dismantled without something equally secure we will simply see a period where people have no choice but to be insecure and then an expensive process where regulation, probably worse regulations, are implemented.

The key point I was trying to make is that the current war does not depend on conscription. We have enough incentive in terms of pay and benifit and enough people with no other skills that we do not need conscription, so the kids have no reason to protest like the did in Vietnam. The other point is, and I am amused that some silly person spent an hour trying to retcon history(like Boehner is trying to do with the government shut down and the impeachment threats(so sarah palin never suggested that we impech obama, only those in the administration) is that those who were directly impacted by his action or indirectly impacted by those who were supporters did not have any recourse. It is like the no fly list now, except the no fly list is secret and does not seem to focus on certain famous US citizens whom the McCarthy type people did like. As far as the various wars of the Veitnam era an the various wars of current Iraq era, they were political, religious, and economic factors in both. Obviously the former was a religious type fanaticism against communism, while the later is a political fanaticism against Islam. The former was to protect us against a Russian aggression through Cuba, while the later to protect us against a radical 'Muslim' aggression through terrorism. In both cases free exploitation of resources, including oil, was a proximate factor. In either case proxy wars are fought. Vietnam instead of China, Iraq instead of Afghanistan(I know we are now in Afghanistan, but the horses were already out, so to speak).

The lesson bieng that one result is a best a guess and worse fraud, and while we want to test the current expectations of physics, a single result provides little information. It is not so much that cold fusion or virtual particles can't provide useful energy, but that the current theory does not show how such a thing is possible and experiment is inconclusive.

In 1950 Joe McCarthy claimed to have a list of communists in government and started a process that destroyed the lives of common US citizens without due process or ability to appeal. In the mid 1960's most young people were against the government because they were being forced to serve their country in the military, which generated a great deal of anti-government sentiment because they did not want to. If we look what is happening today, most of the government overreach does not effect such average of high profile private citizens. For the most part this overreach is seen as only targeting foreigners or terrorists. Susan Sarandon is not being hauled in front of congress and being prevented from working because of what she says. In effect, the government has gotten much more sophisticated at managing the perception of the public. Of course not everyone is governement is so sophisticated. Some are still playing 'there are 400 communists in the Obama white house' card or claiming so other such nonsense and trying to use it to limit rights. But for the most part, the days of stupid seem to be at a lull.

Comment Re:No surprises here (Score 1) 119

The college board is desperate for relevancy. Since 1994 the SAT has changed several times after 50 years of stability to make it more attractive to increasingly critical urban population and schools. It was no longer good enough to see which students matched the standards of east coast prep schools, students had to be characterized based on a more diverse standard. It may have been wrong, but there was simply not enough money to be made catering to the east coast universities looking to rank the east coast preparatory graduates. They are now trying to get funding through the AP exams. The thing you have to know is there are many federal grants that will fund low income students who want to take the AP Exam, money that goes directly to the that the College Board. So, unlike the 20th century when only the best of the best took the AP Exam. There is not enough money in it. There are not people profiting at all levels on students taking the AP exam. Universities, often private, often the best in the area, are training teachers to teach AP classes, mostly paid by federal grants or local tax dollars, a single class generating $10-20 thousand dollars for the university and college board, and there are often dozens of classes offered over the summer. There is the cost of AP books published by the CB as well as past tests which are not free. The College Board is also free to punish or reward districts with awards and direct monetary compensation to various leaders, and these punishments come down to the school level. There are cases where district leaders have reprimanded people at the school level when the leaders did not get their expected rewards. I am not judging what is going on right now. All I am saying is that AP classes are no longer used to filter the best students from the best classes. AP classes are now a way to introduce college level material to interested students. Students who do not want to be in these classes are generally not. Instead of filtering by ability, the filter is a desire to learn. This, of course, means that many students are not able to do the work and get frustrated. Most are not going to do well on the test. But if the class is well taught, these kids will be more ready for college, I would say even more so than a dual credit class. The added benefit is that there is little grade inflation on the test. Students are allowed to fail, then given some information to reflect on that failure. As anyone who has been to college knows this is a critical skill. With the need for every student to graduate, even if they have never attended a class, the AP exam is one of the only way to provide that feedback to college bound students. It is unfortunate, but too many 18 year old adults still think that running home crying to mammy and daddy is a reasonable way to pass a class. The AP test does not finely rank students like so many other test do, and rewards students for their ability to find the questions they know best, and completely those to get enough points to meet their desired goal.

Right now you best deal on a contract phone is buy a new phone when the contract runs out. Otherwise you are paying the fees for a phone that is already paid for. If you sign a new contract, and get a new phone, the amount of money you pay is constant. There is no wasted money. If she was paying for a plan that was out of contract that was a waste of money. Paying $100 is wasted if she was out of contract. Paying $100 in contract would not necessarily be a waste, but it is likely a wash. The value of an iPhone 5S is about $650. If you buy the phone and use something like Cricket it will be $2000 over two years, but there is no lockin. If you get the subsidized phone, and use something like verizon, you are paying a few hundred dollars more over the two year period, with lockin. Most people aren't set up to lay down a few hundred dollars for a phone at time of purchase. Getting a phone for free and paying for a couple years makes more sense. The lockin comes from this extended payment. My fear is that this current climate is leading to higher prices. On verizon, if you use their early upgrade plan you pay about $150 extra over the two years, in addition to the $300 premium.

I don't think any serious person thinks that Galileo woke up one morning and said lets do politics. No, he was at church, the story goes, say the chandeliers swinging, and ended up being persecuted by the politicians of the time.

Most scientists don't take political positions. They make observations, and when a consensus is reached, they sometimes take actions. For instance, when it became pretty clear that lead was dangerous, there was a movement to remove it from gasoline. This became political because some interests were only interested in quarterly profits, not long term costs to taxpayers. Fortunately the taxpayers won. For instance, there is really good science linking the buildup in the environment of lead to the increase in crime, and the decrease in crime of the past decade or so to the decrease in lead. It is not just correlation, cut actual causation.

Now, as far as NPR is concerned, compared to Fox News of course it looks biased. NPR is not going to invite John McCain on the air to talk about when he was a kid you could kill black people, and know he has to deal with a black man, as he has been saying this past week. But the thing about NPR is it probably does a better job of using the public air waves than other.

Here is the rub. Fox News can say and do whatever it wants because it does not use free public resources. This is the key. Free public resources, not funding by the government. The government funds lots of things, and that does not necessarily absolutely limit speech. For instance, many churches take money for schools, which frees up money that they then use to do stuff like encourage people to attack people going about their day to day business. For instance, one church in my area bought cameras so they could photograph people going into a gay club. But radio stations were given public bandwidth and were supposed to use it responsible ways. I think NPR is responsible and balanced compared to some of what I hear on the AM stations. AM stations are using free resources. We could take it back and make a great deal of money leasing it to other agents. We don't. They agree to use it, and should be more responsible.
