I read parts of this in Japanese when a friend was studying statistics. The manga book on cracking (executables) was more interesting, but I just read it for a few minutes in the bookstore. Unfortunately I can't find it on Amazon, but I'm sure Junkudo or Kinokuniya would have a copy.
The books tend to be slow and superficial. Their target audience seems to be people for whom the material would be otherwise inaccessible or uninteresting. If you want to study a given topic, there are better books. If you want to read manga, there are plenty of titles that are more interesting, bizarre or lurid.
Don't bother to mod me up, but the parent should be modded down. Newton is the perfect example of an individual genius, and he changed the world drastically, irrevocably and all by himself. "Everyone still credits" Newton because the calculus wasn't even his biggest accomplishment. He invented classical mechanics by himself. There is no dispute about it.
The greatest minds in the rest of the world were decades behind him, so it's hard to imagine what group he should have been working with. It wasn't just the case with Newton either. Gauss discovered non-Euclidean geometry 30 years before it was published anywhere else.
Before you claim that Newton and Gauss were lying, consider that they didn't have any reason to. Without claiming credit for calculus, Newton would still be the most influential physicist of all time, and there was no peer to Gauss.
I'll admit that for all the rest of us, working in groups will help immensely, but let's not shackle the few truly exceptional people that exist to the mediocre. The solution here is for us not to pretend we're geniuses. Just because it's encouraging to pretend that Newton is just like the rest of us, doesn't mean we should be so dishonest as to pretend it's true.
If you're going to separate the men from the boys, do it the way Knuth intended.;-) Actually, that algorithm ought to pretty good at weeding out the faint of heart in a CS classroom, too.
It isn't strictly true that programming paradigms have nothing to do with algorithms. Due to the vagueness of the term algorithm, there's plenty of room for misunderstanding. However, if you interpret the word algorithm as meaning a finite sequence of explicit instructions, it isn't meaningful to talk about an algorithm in a pure functional language. This is true of any declarative language, by definition.
It isn't just sophistry either. The best solution of a given problem will vary wildly between a procedural implementation and a functional one.
Take a naive recursive definition of the Fibonacci sequence as an example (F(n)=F(n-1)+F(n-2)). In a pure functional language, the compiler is free to use memoization to achieve O(n) in running time and stack usage, whereas in a procedural language the same definition will be O(2^n). An algorithm that uses explicit looping is more appropriate for a procedural implementation. (This ignores the constant time solution that may be available depending on the domain of the function and the floating point precision available.)
There is plenty reason to criticize/. summaries, but I think that in this case your criticism in unfounded. Any algorithm that makes explicit use of mutable variables, looping or side effects cannot be implemented as-is in a purely functional programming language.
Honestly, I don't see what your opinion is on Nimrod. Are you calling Nimrod a primitive, or were you pointing out the sophistication that is credited to early, Middle Eastern culture even by the bible?
Or is it just laughable that you choose to use the name of a great, non-Western historical leader as a derogative while railing against Western Imperialism?
The Japanese have a word for the sensation you get looking at this sort of otherworldly monstrosity. They say oishisou, which literally means, "that looks delicious."
I really ought to just drop it, but I'm waiting for a backup to finish and the following was irresistible.
Utilizing quantum entanglement to transfer information over great distances, instantly, is obviously a genius idea.
The article, and the summary, are about quantum computing, not quantum cryptography or quantum teleportation. That's the significance of the word "computing" in the title. (Here comes the "I already knew that," right?)
But that article summary means nothing to anyone who isn't a hardware engineer.
I'm not an engineer at all, and there was nothing in the least bit difficult to understand about the summary. Does everything have to be dumbed down? How far should we all sink, and to whose standard? If it isn't in pictographs, the illiterate will be excluded!
Sad, really. I'm lucky if I go see a film at the theater once a year. There just aren't enough movies that deserve my money in that regard.
I don't think I've seen a film I really liked at the theater in 5 years, and I go to the theater at least twice a month. However, the kind of people whose company I prefer (read: chicks) seem to enjoy mainstream movies. Two hours isn't that long, and if it gets too boring you can always just close your eyes and think about something interesting, like combinatorics or complex analysis;-)
It's pretty shabby to reward Hollywood with cash for wooden acting on top of brain dead scripts, but just try to get through a month without directly or indirectly paying money to any parasites or thieves.
There's a big difference between "I am not an engineer" and "I don't understand basic units of measure." The concept of absolute zero is something you should have learned in elementary school. I'm not on any pedestal. Maybe you're standing in a ditch.
Even ignoring that, your argument is pretty nonsensical. You say that if the average person doesn't understand the specs it will never have widespread commercial appeal. It doesn't follow that if you don't understand the article summary, that no one else will understand the applications of quantum computers in the future. Unless you think that the summary of this article is the single current and future source of information about quantum computing...
Even if no one understood the specs or even the utility of quantum computers, they could still be commercially successful. Popular understanding of quantum physics wasn't required before personal computers (using transistors) and CDs (using lasers) became successful.
This is not an article about video games. If all of science and technology had to be dumbed down so that you personally could understand it, there wouldn't be any video games for you to play (modelling motion and optics), let alone computers, cars or the controlled use of fire.
If you don't understand something, either educate yourself so you can understand it, or leave it alone. The correct response is not a call to remove the hard sciences from public discussion.
How did you get modded up, anyway? If the average slashdot user agrees with Barbie that "math is hard," it's probably time to let slashdot drown in its own stupidity.
Yes, anything you can get without cost has no economic value (no one will trade for it). Saying freely copyable things are without value is taking economics too seriously. By your argument, air to breathe has no value. Of course there is a utility, but no one will pay for it until they feel a shortage.
So, no one will pay for a copy of an existing item because they can copy it for free. New, unique objects can't simply be copied from old objects, so the first copy does have a value. This means designers and artists can profit, but there's no need for factory owners or publishers to copy originals anymore. Doesn't this increase the profit for, and lower the barriers to entry to, creation?
The objects that are created in SL are essentially software. If objects can be freely copied, then it's very close to BSD or MIT licensed software. Software with those licenses gets produced outside the context of virtual worlds.
That would accomplish what? By what physical mechanism would microwave energy be converted into sound waves? The parent is talking out of his (admittedly venerable) ass, which he more or less admits. The technology works exactly like your microwave oven. It rapidly heats an object using rf energy, in this case a skull, not a baked potato. The only thing that's changed is the power is cycled so that the cyclical heating causes pressure waves. It's the subtle difference in received energy and timing of the rf bursts that makes the difference between boiled brains and auditory hallucinations.

Nobody around here uses them either, but for me it's the least painful way of using the language. If I use generic containers and map (List.ConvertAll) or fold (I had to write a short implementation myself, not that it's difficult. Is there a standard version?), at least I don't have to write any loops. Still, the syntax doesn't feel natural to me (whining, I know) and trying to write purely functional code would be more trouble than it's worth. I thought about implementing a functional IO system for about a second before I went back to what I'm being paid to work on.:-(
They don't always require a license because most people don't have licenses. Getting a license is a multi-month, several thousand dollar (or several hundred thousand yen, actually) ordeal. People that don't live in rural areas don't need cars and in congestion choked cities, cars are mostly luxury items.
The article is pretty skewed. The real story is that Taspo is starting July 1st. Taspo is a card based system that doesn't use any age verification. It's being deployed nationwide. You have to apply for a Taspo card using some form of state-issued photo identification. Maybe there's a weak link in the application procedure, but only one card is issued per person and cards that have been lost or are being abused can be disabled remotely.
The article says that there will be 4000 age verification machines (in a country of 130 million), but I've never seen one. Every day, I see dozens of machines that say Taspo will be required starting July 1st. All the smokers I know have Taspo cards.
I'm sure it probably isn't, but it reminds me a lot of Sakaigawa in Machida. Thinking about it, all the little rivers look like that. Even further off-topic, it would be nice to talk to a fellow slashdotter. If you want to get a beer in Akihabara some time, send me an email.
Sorry to pick on you, but I've just exceeded my daily limit of oversimplified anti-government rants. It isn't personal. There are bad things about government. Noone likes paying taxes and being (implicitly) threatened with death or imprisonment by a police force and army. Supporting a government often means supporting decisions that conflict with one's personal values and morals, for example paying taxes to a government that executes criminals or provides abortions. The people in power tend to be the same rich or powerful people that are always in power; there's no real equality. The important things that governments provide are greater stability, peace and order. Maybe a government is only an instrument of the powerful to secure these things for themselves at the expense of the less powerful, but stability and order benefit everyone. It's illustrative to look at historical and modern examples of governmental collapse. Anarchy leads to starvation, violence and, eventually, rule by warlords. Whether it's rich white men in a city far away, or a gang of young men with automatic weapons on your block, someone will seize power. Strong centralized government is just a more stable and less chaotic, less violent choice. Of course there are times when revolution is in order, but unless a new government replaces the old one, there's little hope for positive change.
That you don't discriminate between dirty bombs (not even nuclear weapons), salted bombs (designed to maximize radiation due to fallout) and neutron bombs (designed to maximize neutron radiation from fusion) means that you shouldn't criticize the accuracy or competence of others. And in your world there have been thousands of nuclear detonations in western Europe... As opposed to the reality of TWO wartime uses of nuclear weapons. You would do better to read more and write less.
thats not true, there is just a small group ho is "ethnocentric". I live here for more than fives years and have not yet had direct contact with any of those "ethnocentric" groups. all Japs I met were absolutely friendly and open to foreigners. The parent either lives with his eyes (and ears) closed or is just plain trolling. Anyone who's spent more than a day or two in a Japanese city has heard the ultra-nationalists in their vans blaring music that sounds pre-1950's. But beyond that, people are openly racist is a way that would draw gasps and demands for political correctness training in America. They aren't what Americans might imagine as hate-filled bigots, but they openly discuss traits they perceive to be common to certain nationalities or races. They wouldn't think twice about (for instance) not hiring someone because of their race (or nationality, or age or sex or orientation). Often job applications require a photo along with the applicant's resume.
You just insinuated that velocity scales linearly with energy and got a +5 Insightful for it! Never mind that at Mach 32, drag will almost certainly be larger than 1 G.
Here's my bid for +5, Insightful: maybe if we glued feathers to the projectiles, they'd fly better. Be careful not to use wax, though. If you get too close to the sun, the feathers fall off.:-(
In order to make a paper airplane that can fall back to Earth from a space station, the Japan Origami Paper Airplane Group and Tokyo University have been brought together. Using the University's wind tunnel, testing was performed on the 17th.
In the experiment an 8 cm long paper airplane, folded into the shape of the space shuttle, was made of material that had been treated for heat resistance. It was tested for heat resistance and strength in a Mach 7 airflow generated by the ultra high speed wind tunnel located at Todai's Kashiwa Campus (Kashiwa City, Chiba Prefecture).
Space vehicles such as the Space Shuttle can reach speeds of Mach 20 on reentry and due to the high temperatures caused friction with the atomosphere, their surfaces require special heat resistance devices. Because of the low weight of the paper airplane, it will begin deceleration from where the atmosphere is thin and be able to land slowly. It is said that it may be able to return to Earth without burning up.
Shinji Suzuki, professor of aerospace engineering at Tokyo University, shared his dream. "I want to fly it from the Space Station with a message of peace. I don't know where in the world it will land, but hopefully the person who finds it report it."
$8.75/person? I just went to the theater the other day and it was about that... since the price was nearly half off for a special they run on the first day of the month. It normally costs 1800 yen ($15.25) at the theater I went to. For premier movies, it costs 3000 yen ($25) per ticket. I wasn't expecting the discount and my date paid for herself, so it was really cheap.
I must be insane to ask on slashdot, but is it the kiss of death when your date insists on splitting the bill? Maybe it's more the friendly handshake of death than the kiss of death.:-(
