The commitment to memory of compartmentalized and seemingly unrelated facts and figures, despite being so overused by primary and secondary schooling systems in most civilized countries, is an inefficient tool compared to concept learning, and will ultimately lead to a society of people utterly incapable of innovation for lack of awareness of the why behind any of the many hows that they have memorized.
This is the only part of your spiel that I agree with. It, however, is not a problem with calculators and technology. Rather, It is a problem with our society and the attitude it instills in children. I am a very successful student because I am interested in the material. Parents do not instill interest in their children, and the culture of their peers does not help either. For this to be remedied, it would have to be remedied in our culture not with the deprevation of calculators.
Calculators are useful tools. Graphing calculators are extremely valuable in teaching visualization of mathematical functions. As for being error prone, maybe the last calculator you used was a scientific calculator? My Ti-89 has a complete history of actions, and I can see everything I am requesting while I enter it. I am able to correct my errors as I make them. I, however, have had the recent unfortunate experience of taking a Calculus 3 class where only scientific calculators were allowed. (There was no good reason for this as everything we learned was conceptual. ) Those _are_ very error prone. (Especially if you're using an old one where the buttons you press don't always register.) Since you are unable to see what you have requested.

I had this exact f*cking experience on a f*cking Calculus 3 exam this previous semester. I got an A, but talk about b*llsh*t. Since when is Calc 3 supposed to be testing you on arithmetic?
Not to mention the FUD here. Read the top sentence in bold.
The PowerPC G5 out-shoots the Pentium 4 in a battery of tests. But it's in the rough-and-tumble of real-world performance that the G5 really shines -- shredding the PC's reputation in the process.

And the developers boycotting apple. Not only do they have to relearn all the ASM tricks they learned for the PPC, but they have to fork out 1000 dollars in order to LEASE a developer box for 2 years. Yes you heard me, LEASE a developer box.
There is no error with apples slogan. It is instructing you in what to think about their product. As in, "Think that our product IS different." Not think differently about our product, but that our product is different from the rest of computers.
On a side note though, then and than are completely different words and are misused only due to their phoenetic similarities. Like "you're" and "your." This is not necessarily a good thing. Although, if you can distinguish them in verbal communication, maybe it's not such a big deal when the word is spelled incorrectly?
What's the transfer speed on these? My ATA133 Hard Drive only gets about 40 MegaBytes a second last time I benchmarked it. Based on my understanding, that is pretty decent hard drive performance. How long does it take to burn one of these disks? If my HD is only 40mB/sec, I can't possibly burn faster than that At that rate it'd take 41 minutes to burn one of these. Last I checked DVD burners don't even get close to 40mB/sec
Pretty much all schools have SSNs, and it is pretty friggin' lame. Most schools use them as Unique Identifiers instead of coming up with their own ID system.
Question
Why is heavy water poisonous?
Asked by: Unknown
Answer
That's a very interesting question. There have been no detailed studies carried out that I am aware of, but decades ago a crude experiment was done in which mice were given water which had various percentages of heavy water, which is water in which both hydrogen atoms were replaced by deuterium. Low percentages of heavy water didn't have noticeable effects, but more than 20% heavy water did have adverse health effects and mice given 80% heavy water died within days. In another experiment, bean plants grown from seed given increasing fractions of heavy water showed stunted growth compared with control plants given normal water.
The reason for these adverse effects is that replacing hydrogen with its heavier isotope deuterium slows down the rate of any chemical reaction in which the chemical bond to the hydrogen atom is broken. This includes a great many chemical reactions occurring in biological systems, and not just those involving water; the hydrogen atoms from water end up in a number of other biomolecules, so any process involving these hydrogen atoms will also be slowed down. Thus the heavy water acts like a brake on a large number of metabolic processes.
The amount by which an isotopic substitution like this slows down a chemical reaction is called a kinetic isotope effect. Such effects are a major tool in the study of chemical reactions, including enzymatic reactions. Deuterium isotope effects can be as large as 6 or 7, which means that the reaction rate is 6 or 7 times slower when deuterium is substituted for hydrogen. In rare cases where a quantum mechanical effect called tunneling occurs in the reaction, deuterium isotope effects of 20 or more have been observed.
The major reason for the difference in the rates of the chemical reactions involving the two isotopes of hydrogen is the difference in their masses. Deuterium atoms have an atomic mass of 2, which is double that of normal hydrogen. Of course other atoms have isotopes also, and your comment that for isotopes of other elements these effects would not be present is perceptive but not quite completely correct. Isotope effects do occur with the heavier elements but they are much smaller. For instance if we replaced the oxygen of water (which is normally oxygen 16) with oxygen 18 we end up with a water molecule having the same mass as in the heavy water discussed above, but in which the isotope effects on its reactions would be very small. This is because changing the oxygen atom's mass from 16 to 18 is a much smaller fractional change than the doubling of mass of hydrogen when we go from hydrogen to deuterium. Oxygen-18 isotope effects are never more than about 1.07, or 7 % slower with the heavier isotope.

(no cookies --> no way for google to check whether I have gmail)
This isn't exactly true. There are other non-cookie methods of unique identification. If you say, logged into your Gmail account first. (Such as storing info based on IP for a certain time) They're not persistant between sessions though.
It's nice to be the physically smallest rom, but what about power consumption (static and dynamic)? Also, what about access time (usually you have to balance power consumption and access time... you get one at the expense of the other).
This is ROM as you astutely pointed out. ROM is not classified as "static" or "dynamic." It's Read Only Memory. As the data is permanently(non-volatile) stored it's power requirements should be very small.

I was noticing that too. The book actually describes lucy as curiously looking into it, and then having to hide in it when she hears the person who is IT coming into the room.
