1. The study doesn't concern itself with hard mathematical questions. It is based on common math tests, aka No Child Left Behind mandated state tests.
2. The fact that the standardized test material contained "not many" (different from "no") hard mathematical questions is an aside from the point and conclusion of the study.
3. There is no trend reversal. It just shows that mathematical proficiency with respect appears to be very dependent on cultural factors. The study still shows that boys are better than math, just only among whites.
There might be problems with the study, but if so, they are a lot more subtle than you seem to believe.
Even when masked, the squares still appear discolored because the right square is still set against a blue background, and the left square is still set against a red background.
Setting the mask makes the effect a lot more muted because the backgrounds are dark. The only way to notice it is to have the squares right next to each other in your field of vision, which can only be done by uncrossing (crossing?) your eyes.
I assumed the new standard would be very limited in scope to making it easier to solve fundamental web markup problems. Sadly at first blush, some of the new elements seem awfully bad.
Contexts in which this element may be used:
Where block-level elements are expected. Content model:
Zero or more pairs of dt and dd elements. Element-specific attributes:
None. DOM interface:
No difference from HTMLElement.
The dialog element represents a conversation.
Each part of the conversation must have an explicit talker (or speaker) given by a dt element, and a discourse (or quote) given by a dd element.
This example demonstrates this using an extract from Abbot and Costello's famous sketch, Who's on first:
<dialog>
<dt> Costello
<dd> Look, you gotta first baseman?
<dt> Abbott
<dd> Certainly.
<dt> Costello
<dd> Who's playing first?
<dt> Abbott
<dd> That's right.
<dt> Costello
<dd> When you pay off the first baseman every month, who gets the money?
<dt> Abbott
<dd> Every dollar of it. </dialog>
Text in a dt element in a dialog element is implicitly the source of the text given in the following dd element, and the contents of the dd element are implicitly a quote from that speaker. There is thus no need to include cite, q, or blockquote elements in this markup. Indeed, a q element inside a dd element in a conversation would actually imply the person talking were themselves quoting someone else. See the cite, q, and blockquote elements for other ways to cite or quote.
I am sure that Mitsubishi Bank, Mitsubishi Agricultural Machinery, Mitsubishi Estate Co., Mitsubishi Plastics, Mitsubishi Electric, &ct. would disagree with your "Core Competencies" analysis.
The core product in the Mitsubishi brand is not cars or electronics. Their core product has always been venture research. Be the first and best in new fields. If anything, I am surprised they don't have a Mitsubishi Pharmaceutical yet.
Quoting the GP no one read, which quotes the article no one read:
Mr. Dunn said most of the new rules were reasonable. Notably, someone using a hand-held video camera, as Mr. Sharma was doing, would no longer have to get a permit.
The law eliminates the mechanism that justified his arrest. This is a good thing.
How you were modded up is beyond my comprehension.
Instead of invalidating software patents, we could shorten their term to a reasonable period (two or three years generally ensures obsolescence for most software products), and drastically expand the criteria against which a particular software patent is judged invalid. Would that not be at least a workable compromise?
That is simply absurd. Two or three years seems like a reasonable period a junk patent, but this is terribly unfair for meaningful discoveries which arguably justify a patent, like RSA.
Hypothetically, let us say that a researcher independently discovered a new algorithm which performed discrete Fourier transformations 2x faster than anything we have today. The commercial and societal value of this discovery is pretty huge. Two or three years of exclusivity couldn't do justice to the impact of this huge discovery.
(No, I am not endorsing patents on algorithms. RSA shouldn't have been patentable. It's just shortened patent periods is not a reasonable compromise, and far from 'Insightful')
If you're going to sell someone a $54,000 server, you damn well want to make sure it uses as robust an operating system behind it as possible. When you're in the business of buying and selling SPARCs, charging for OS licenses is just nickel and dime stuff.
Note that coal power plants are the "the largest uncontrolled industrial source of mercury emissions in Canada". According to the Environmental Protection Agency (EPA), (when coal power is used) the mercury released from powering an incandescent bulb for five years exceeds the total of (a) the mercury released by powering a comparably luminous CFL for the same period and (b) the mercury contained in the lamp. It should be noted, however that the "EPA is implementing policies to reduce airborne mercury emissions. Under regulations issued in 2005, coal-fired power plants will need to reduce their emissions by 70 percent by 2018.". This change will lengthen the term before CFLs are better than incandescents. If CFLs are recycled and the mercury reclaimed, the equation tilts towards CFLs, and if non-coal sources of electricity are used, the equation tilts toward incandescents.
Christian Science Monitor had a commentary about this ruling. To sum it up for the/. crowd -- age-verification laws exist for pretty much any other pornography sold in the United States, the internet should not be an exception. Fundamentally she's correct, although, IMO, COPA itself would realistically have a trivial effect on kids seeing porn, since it just pushes providers off-shore.
Additionally, here's SCOTA's case summary and opinions on this law. The ruling on this was 5-4, same votes per judge as in United States v. Playboy Entertainment Group (which struck down a much broader version of the same law). Basically... you guys are one justice away from a very different internet. Consider yourself lucky it was Rehnquist that died and not Kennedy.
Personally, I have a problem with the fact that our obscenity laws revolve around Ginzburg vs United States -- a ruling from 40 years ago during the middle of the sexual revolution.
Very true. There was nothing white-hat about this. He was cracking and back-dooring. He never "pointed out that their passwords were terrible". He just cracked passwords so he could hog CPU and install backdoors.
The logic behind his extradition is that because he "controlled access to the so-called drop site, located on a computer network at the Massachusetts Institute of Technology", jurisdiction is in the US. Got this from an article about Hew Raymond Griffiths
There was an old slashdot interview with one of the DoD Leaders caught in the MIT raid.
The whole "jurisdiction is wherever your computer is" deal doesn't sit easy with me. Quite honestly, I don't know where most of the servers I use are physically located.
Ok, there's been quite a number of posts saying this same thing, and I just don't get it... so to use the above analogy...
6 months later, you see the plate on EBay, drawing insipid bidding, reflecting relatively low demand, stuck at $158. Your web design business has been doing well, and you can afford $200 to get back in grace with your wife. You therefore bid $200, raising the current price to $160. On the final day, you win the bid.
In both scenarios, one bids on the item because it is priced below what you are willing to pay.
In both scenarios, you pay the same amount.
In both scenarios, the seller has exactly the same amount of information... that you are willing to pay at least $160 for the item.
Yes, it's frustrating that the seller gives you the illusion of being able to get the item at far below what it was worth to you, but in practical terms, it makes no other difference to the buyer.
On the other hand, the seller is, by using an artificial base price, is defrauding EBay out of listing fees. The OP's suggestion that EBay is somehow complicit in this makes no sense.
There's only one other career I know of where blatantly insulting your customers is acceptable, and that's stand-up comic. (Of course being a comic also requires you to be funny, and material like select * from users where clue > 0 isn't funny.)
I laughed...
If I might suggest another way of thinking about it that really lays out how undefined 0/0 really is.
Given 0/0, we approach it as a limit problem. The real problem with it is there's too many ways to approach the limit. For all possible values of Y and X, there exists a limit such that 0/0 -> Y/X.
You are completely correct about NaN of course! However, 0/0 is much more than that. It's the purest example of undefined result. Operations which have a solution set of "Every possible value... including infinity", end up being the shadows of 0/0.
Also, 0/0 isn't a problem of real numbers. It is a problem that translates into any set for which 0 and the division operator exist. Who says Y and X need be real values instead of say... complex numbers? N-dimensional vectors? SQL Tables?
It appears that in the article he is using the term "Interactive Storytelling" to mean what is more commonly called "Interactive Fiction".
Basically.. it's text based adventure games. They stopped being commercially produced about 20 years ago. However, due to the ease of creating them, there are many freeware games out there. If you're really interested in seeing what the big deal is about, I'd suggest giving Zork a spin -- it has aged rather gracefully.
The article is frustratingly vague, but it basically seems to be about making it easier to produce better interactive fiction. While IF is currently easy to put out, it tends to be pretty bad due to horrid language parsing.
The article posted is a bit... Let's just say that the Businesweek article covering this has a much less "Wal-Mart is EEEEVIL" ring to it. I know it feels good to pat yourself on the back with the Coorporate hate feelings, but this NY Post article has a pretty blatant and nasty slant that shouldn't have make it to the slashdot front page.
FTA:
"If you get your hand on this manual, you can basically reconfigure the ATM if the default password was not changed." (Emphasis mine)
The article is about the ease with which one can find the operators manual.. which is a shame, because it entirely misses the point. "ATM Installers use the default password!" is more appropriate.
I recently graduated with a BS in Mathematics. High school was not very long ago, and there we were required to use graphing calculators for Junior and Senior level math classes. To this day, I don't understand the purpose of having students buy graphing calculators.
Graphing calculators have the problem of really dumbing things down. Learning how to use the calculator is a bit of a hurdle... but once you do, you can get by without learning the quadratic equation, how to convert from moles to grams, what the relation between physical and kinetic energy is, &ct. It's expected that most of this will come with the calculator, but that which doesn't is a simple exercise in typing to fix.
Also, there is a problem of monetary cost. $100 may not be a lot to most people, but it is for a few. It's money that could be much better spent too. Think about it... $100 per high school student, in a system where you have roughly one math teacher for every two hundred students?
So what do we get in exchange for this? There's two productive uses of a graphing calculator. The first, institutional use, is that kids will understand Analytical Geometry and Trig better if they can SEE equations. It's easy to imagine how this might help a kid understand how to push around equations like F(x-x0) + y0. It's just not a very useful thing to learn. I know calculators are capable of so much more, graphing Crossed Troughs and whatnought, but that's too far beyong what you learn in high school to be meaningful.
The other benefit merits a bit of appreciation... the student recreational use. If you give a kid a ball and free time, he'll kick it. If you give a kid a programmable machine and free time, he'll program it. Even so, very few students actually do this. It's encouraging to see kids compare their text adventures with each other, but but 95% of the student body, this toy is pearls before swine.
Graphing calculators, not wholly without benefits, do not outweigh the problems they cause. Ironically, the place they deal the most damage is probably math, because we end up with kids getting by without understanding order of operations or basic algebraic manipulation. Give schools robotics teams, not calculators.

Feh. If it doesn't have more backslashes than you can count on one hand, it's probably not worth writing.

I'm sorry... but this article is drivel. I mean, this is bad for slashdot. It's a month old story, from a joke of a newspaper source.
