If one exerts a centripetal force on an object to constrain it into circular motion, then the object exerts a centrifugal force in reaction. Newton's 3rd law.
I'm going to nitpick here -- If object A exerts a force on B, causing B to go in a circle (that's the centripetal force), then you are correct that by Newton's third law, B also exerts an oppositely directed force on A. However, that force is not what is commonly called "centrifugal force," which is a pseudoforce felt by B in its accelerating frame of reference.
Whether or not you want to call centrifugal force real or not depends on how you define "real." It certainly has as much justification as many other mathematical constructs and simplifications used in physics.
Publishers have figured out how to use electronic class material, and it's going to be more expensive, not less. My personal favorite: I tutored for a class where the students paid $120+ for a 200-page, paperback textbook, and a 1-year subscription to a very poorly done website necessary for the class. So now they save money by not printing all of the material, charge you as much as a full book would cost... and then the used book is only worth a fraction of its new price.
I know a lot of universites are getting upset with how some companies release a new edition every year with maybe or or two minor changes and make the university proffesors change all their problem sets to adapt
Nobody in power at the universities is "upset" about it. They absolutely love it -- their professors write the books, and they usually own the bookstores and get a cut of the profits. Yes, when talking to the students they will put on the facade that they want to "do something" about the textbook situation, but don't hold your breath. These guys could teach everyone in Washington a thing or two about making promises you don't intend to keep.
the thing is downmods reduce karma. This makes people take them personally since if you lose too much karma the starting score of your posts goes down and you could possiblly even end up banned.
It's just a couple points. No damage is going to be done by an occasional downmod if the poster generally contributes to discussions in a positive way. If someone is getting modded down so often for making redundant posts that it puts them in danger of being banned, then perhaps they need to stop posting things that are so obvious.
Out of interest if you belived your post to be offtopic why did you use karma bonus to post it at +2?
I figured that it was something that moderators could benefit from reading, as there's far too much lousy moderation that goes on on this site. The karma bonus means higher visibility.
it may be second in line, but both posts were at the same time, and only one slashdot post lies inbetween, theyre probably within the same second or two even. Redundant is a bit unfair.
Redundant is not unfair, it's accurate. Moderation should not treated as some sort of reward system for "good posters," it should be used to improve the quality of discussion. If two posts are largely the same, it makes the discussion easier to read and participate in if only one shows up in normal browsing. Posters should just realize that a downmod is not neccessarily a personal insult; it may just be a way to improve the conversation.
And incidentally, moderators, my post is "Offtopic". Please handle it appropriately.
Tell you what -- when you win the 10,000 song gift card, give it to me and I'll buy you a pizza. Certainly that has more value to you than the 10,000 iTunes songs, right? And though I don't use iTunes or have an iPod, I suspect that I can probably come up with a use for such a prize, if I try really hard.
It's just stupid and impinges on the legal users of that bandwidth at the school.
You don't seem to understand the motivation for this. Illegal downloads take a huge toll on the internet connections at universities, because so many people are downloading the latest Britney Spears that the network becomes unusable for anyone else. The restrictions are intended to help the legal users of the bandwidth.
It could easily be the case that if series A is commercially available, and series B is freely available via fansubs, that people will choose to watch series B over series A because of the cost. Thus, the fansubs could impact the sales of a different, commercially available series.
Not mozilla, but here's a site that blocks you if you use Opera: http://www.environmentalchemistry.com/. It's been linked to on a couple slashdot posts, and so after I sent the webmasters a note telling them what I thought, I added it to my hosts file pointing to 0.0.0.0 so I won't click through to it again.
It would have been nice if they have to post something of his, if it had at least been a marginally newsworthy story. Of all the crap he comes up with, was this really the most interesting?
Unless you want that overflow you found to get patched, pick and choose your targets carefully.
Given that most of the heavy-hitting worms and malware use already-patched exploits, I don't think that this is all that much of a concern to the typical script kiddie.
And his comment is at +5. Just goes to show that despite all the complaints about bad statistics in this story, the moderators love an unsubstantiated number that fits their preconceptions as well as anyone else.
It takes more energy to accelerate quicker than it does to accelerate slower.
As a blanket statement, this is false. Going from zero to sixty in ten seconds may end up requiring more work than doing the same in twenty seconds. However, depending on the engine, the gears, the wheels, the road, and all sorts of other factors, it may not. It's a complex problem that can't be solved via simple analysis.
He's not missing the point; he understood completely. It's not their job to give it to you in every format on the planet. If you think that the price is too steep, perhaps you just shouldn't buy it. Claiming that you "need" to buy them all reminds me of those who say that by releasing a special edition, the director "forces" them to buy it again. Just show a little self-control.
Screen sci-fi has finally caught up with written science fiction. We're in college now. High school is over. There's just no need for "Star Trek" anymore.
Remember, this is by Orson Scott Card, author of some of the most derivative juvenile science fiction I've ever read. If there's anyone unqualified to make this particular judgement about science fiction, he's it.
Don't get me wrong, these messages shouldn't be marked as spam,
See, this is where you get into the realm of what some people consider appropriate, and some don't. I'm of the opinion that any message that was mailed to thousands of recipients most certainly should be marked as spam. If I sign up for a mailing list, I can whitelist it myself. If you trust your ISP to do your spam filtering without any input from you... well, of course not everyone is going to be satisfied with the results.
Do you have any evidence at all that they didn't? Unless you have some reason to think that it isn't, I would give them the benefit of the doubt. The source code, as given, is in an easily modifiable and compilable state.
You're really reaching for an excuse to call this illegal. The intent of the quoted phrase from the GPL is to prevent people from releasing source code by running it through an obfuscator and then distributing it on punchcards.
Alienating 50% of your potential customers -- especially when you're targeting a fairly small group -- is hardly guaranteed to be a recipe for success. It may work in some cases, but it could backfire just as easily.
Regardless, that wasn't really my point. Your statement was that they're on the right track if more people like than dislike the ad. How about the scenario when one ad is split 55 "like" / 45 "dislike", and another is split 75 "like" / 25 "indifferent".
As long as people who agree with me outnumber the people who share your opinion, then they're on the right track.
Back that one up a bit -- relative percentages have nothing to do with it. What's better from a marketing perspective -- an ad that 50% of your potential audience really likes, and 50% of of them really dislike, or an ad that 100% of your audience likes?
Not that I'm commenting on the effectiveness of this particular ad.
Rich people have no right to screw poor people with illegal contracts
Contracts cannot force people to do illegal things
Those are all reasons why you can't do something if it's already illegal. None of them are reasons to make selling DRM-protected media illegal. I'm with the parent poster 100% -- this shouldn't be any of the government's business. Glad I don't live in France.
Literacy tests and grandfather clauses in the South were applied consistently to both white and black voters, too. That didn't make them non-discriminatory.
My thoughts? If the editors can't be bothered to glance at the last dozen stories posted on the front page before posting a new story, they won't review a computer-generated list of potential dupes either.
How's this for a solution: if an editor posts a dupe, he doesn't get paid that day. Maybe that would actually get them to pay attention.

Of course, those two categories also make (2) and (3) rather redundant...
