If a computer can solve the problem, students shouldn't have to exhaustively memorize the mechanics of the method. What's the excuse? That later on the students won't have the computer available as an aid? Still today the world is filled with highly educated old people who would not be able to grasp the functioning of a system like W|A, and who still prides themselves of how, in their time, they really learned math because they did not have calculators and had to solve their fancy arithmetic by hand.
Instructors should stop being lazy and ask questions that require some thinking, questions that a computer would not be able to answer unassisted by a human who fully understands the problem. Within the questions, make the students show that they understand the concepts behind the method, rather than asking for endless repetition of an algorithm with pencil and paper, and later complaining that they found a more efficient way of doing it.
If the constitution guarantees the right to privacy, it should not matter whether this privacy may be violated in the physical or digital worlds. Your basic online rights should be ideally imbued in your constitutional rights. The fact that there are many more ways to invade your privacy digitally means that this right should be more strongly enforced digitally.
If you have a long tube with nothing but vacuum inside it you can drastically increase the efficiency of such a device. The problem is the end of the device has to exit into something near vacuum or it would be like slamming into a solid wall made of atmosphere. If a tower like this could be built such that it contained a vacuum corridor inside it then we could perhaps finally pursue this idea with already existing technologies.
Now all we need is the help from Maxwell's demon to keep an open ended vessel at a vacuum.
The thermal energy that can be utilized from harnessing waste heat from the server farm is proportional to the the temperature of the heated fluid.
It is true that water is a better medium for storing and transferring heat, but if the goal is to be able to run the servers cooler, then that lower temperature is the maximum temperature they will be able to heat the water to.
Plus, it also boils down to fixed costs. Is it much more expensive to install large heat exchangers that would transfer the heat from cooling air to water (allowing it to reach higher temperatures) than to install the water cooling system in each server?
It's clear that your personal experience with women around you, though valid, is not a basis for any generalization.
However, you are missing the point of the criticism. Dell's marketers may have their opinions about women behavior, but they are assuming that these traits are more relevant for the purchase of a laptop than any knowledge about the machine in question.
I don't believe that the only people willing to pay for the textbooks will do so simply for altruism. There is a value in the printed edition apart from the content.
Moreover, distributing free digital copies may generate enough visibility that their sales could surpass those of less publicized titles.
The study is more of a comparison of the efficiencies of internal combustion engines and electric motors to power cars.
FTFA:
"The internal combustion engine just isn't very efficient, especially when compared to electric vehicles," says Campbell. "Even the best ethanol-producing technologies with hybrid vehicles aren't enough to overcome this."
The problem is that Wikipedia does not recognise experts or primary sources. In the eyes of Wikipedia, everyone is the same plankton level contributor...
Much to the contrary. That's not the problem, but the power of Wikipedia. Information within articles has to withstand the test of continuous scrutiny, irrespectively of whether it came from an "expert" or from a complete layman.
If the piece of content is backed by a simple Google search but it's correct, the problem does not exist. If it's incorrect, stronger sources with the correct information will be used to contest the faulty one.
When researchers don't address a loss of a 3rd of their sample they are not doing their job. Something is fishy from that end.
66% completion rates for clinical trials are not uncommon and do not necessarily imply problems with the medication. Keep in mind that participants in clinical trials are commonly given the freedom to leave at their will.
Also who wants only a 1/100 chance of NOT getting your SO pregnant?
It's quite the opposite. 99/100 of the men in the trials did not father a child, at least as far as they know or the researchers were informed. But keep in mind that this number does not reflect the chances a person has of conceiving in a single intercourse. If that was the case, after 10 times the chance of pregnancy would be around 10%, and after 100 times it would be close to 65%.
Naturally, the success rate and, most importantly, the fraction of false positives are not provided. Without these numbers, it's not only useless, but misleading and dangerous.
Find an industry that would otherwise need a gas fired boiler and on-sell the heat.
To generate even low pressure steam at 75 psig, water should be heated to around 160C (320F), which is not possible with the heat extracted from a datacenter. (Even if it was possible, the largest energy input for steam production is the phase change. Also, steam producers usually operate in a closed loop with condensate returning to the boiler at temperatures close to saturation)
The challenge to recuperating the thermal energy from datacenters lies on the low temperatures generated.
...you would plant false data into the same computer which was compromised. When the Chinese hacker returns to it to download even more information, then he would get gigabytes of fake data.
You are delusional. And you need to keep in mind the underlying truth of Hanlon's razor.
A huge amount of effort and money has been put into creating the stolen documents. Do you really think that it would be easy to create credible fakes? Even if they would choose to make very small but key modifications, do you really think that purposely handing out the bulk of the files, which would be unadulterated information, would be worth the unlikely scenario that the modified drawings would provide an advantage in a battle that will not happen?
You are assuming that different groups in a given area tend to be politically homogeneous. Or, at least, that people in the tech industry tend to follow the average political view around them.
The cause-effect relationship is inverted. Most likely, the tech industry, especially the young and innovative part, have an influence in the political leaning of the Silicon Valley and San Francisco.
But your initial point is right: political leaning is not simply a result of pragmatism towards which party will likely benefit their employer and themselves in the short term.
Here is how Merriam-Webster defines "Conservatism":
1capitalized a: the principles and policies of a Conservative party b: the Conservative party
2 a: disposition in politics to preserve what is established b: a political philosophy based on tradition and social stability, stressing established institutions, and preferring gradual development to abrupt change ; specifically : such a philosophy calling for lower taxes, limited government regulation of business and investing, a strong national defense, and individual financial responsibility for personal needs (as retirement income or health-care coverage)
3: the tendency to prefer an existing or traditional situation to change
And "Liberalism":
1: the quality or state of being liberal.
2a often capitalized : a movement in modern Protestantism emphasizing intellectual liberty and the spiritual and ethical content of Christianity. b: a theory in economics emphasizing individual freedom from restraint and usually based on free competition, the self-regulating market, and the gold standard. c: a political philosophy based on belief in progress, the essential goodness of the human race, and the autonomy of the individual and standing for the protection of political and civil liberties. d capitalized : the principles and policies of a Liberal party
Which one sounds more like the mindset to be expected from Silicon Valley?

Not a problem. By the time this would get ready to be built, all our energy will be provided by nuclear fusion.
(Certainly controlled nuclear fusion seems much more feasible than this nonsense)
While I agree with the author's motivation, classifying dogs into different species would require the definition of species to be changed.
This lack of consistency would, contrary to the author's goals, strengthen the creationist stance that science is arbitrary and not to be trusted.

Don't bother. That was probably the last one.
AND end with 1...this must be a conspiracy
Except for 10, of course.

Perhaps a good buy, as Tamiflu is said to help.
The Bird Flu scare did not seem to help. I don't see why this would.
