Sure. But from a global economic perspective, in most cases there is no reason why you should lug two tons of vehicle around on the train. Also, staying in the car would would lose much of the comfort advantages of a train. Shared or rental cars at the stations would be more economic - but they miss the "mine" factor, of course.
Our ancestors had a network of rails all over the U.S. which acted as the backbone of the nation during the 1800s and early 1900s. Then in the 1930 and 40s they abandoned them. Why?
Well, the fact that the road network is nearly fully state-sponsored may have something to do with it...see e.g. Interstate Highway system.
Your references 2 and 3 are irrelevant, as they deal with the a-posteriori probability, i.e. they look at known offspring with problems and the possible causes for their problems. All of the studies are very small.
Please refer back to my request for PROOF. Your attempt to turn correlation into the proof is pathetic, and not scientific in any way.
Strictly speaking, there is no "proof" in science. But there is extremely convincing evidence. First, we are actually emitting somewhat more CO2 than the observed atmospheric increase. If you postulate some other source, where is our CO2 ending up? (The "missing" CO2 is mostly absorbed by the oceans, which become measurably more acidic (CO2 in solution forms carbonic acid)). Secondly, we see a decrease in atmospheric oxygen that is compatible with the burning of fossil fuels to create CO2. And thirdly, carbon from fossil fuels contains little to no of the heavier isotopes C13 and C14. And we see a shift in the isotopic ratios of the carbon in atmospheric CO2 that again is compatible with the new CO2 coming from the combustion of fossil carbon sources.
We also know in the UK the romans (circa 100BC) grew grapes almost up to the scottish borders, something not possible today because it's too cold.
That's wrong. Wine can be grown up to the Scottish border now. In fact, there are vineyards in Gotland now. But wine is a lousy indicator for climate, since its governed not only by climate, but by supply and demand (why make sour wine in Aberdeen when you can get a bottle of Chianti for UKP3.49 in the supermarket?) and, at least in Europe, by EU subsidies.
Al Gore's "inconvenient truth" (really Big Fat Lie, which makes him Big Fat Liar) not only was less scientifically accurate than the sci-fi movie "The Day After Tomorrow", but is actually banned from being shown to schoolkids in Britain because it is so inaccurate.
Wrong."The court ruled that the film was substantially founded upon scientific research and fact and could continue to be shown, but it had a degree of political bias such that teachers would be required to explain the context via guidance notes issued to schools along with the film."
The movie has generally received good marks for accuracy from scientists. It's not perfect, of course (and I found it boring), but what do you expect if you put decades of research into 90 minutes? It gets the core points right.
Whatever unique code is used in the asset register, use that as your workstation name.
This, as many above, seems to suggest that the names are arbitrary identifiers only used for administrative purposes.
But is some real situations, all those computers are UNIX boxes, and users need to log in into specific ones (yes, even workstations), and remember which one is which. A 20 letter+digit white noise name is very unlikely to be remembered properly.
Should we be building more private prisons to hold them cheaply, or should we be cherishing them and making sure they don't see Janet Jackson's nipple?
Why, of course we put them into prisons, both private and public, with no access to TV, or the Internet, or subversive books (like Huckleberry Finn or Common Sense, or Winnie-the-Pooh), to protect them from dangerous nipples and thoughts. Exceptions can be made for Good Kids (tm) by giving them access to selected chapters of the KJV and Conservapedia.
What do you mean by "better"? It's better to go for a Master's, and then for a Ph.D. You will learn more and different things, and you will have a great time. This may or may not translate to a better salary later on. But at least for me, a deeper understanding of the subject is very satisfying on its own.
I'm sorry. Where do we have a right to copy others' work?
Do you mean legally or morally? Legally, there are several cases in which we are indeed allowed to copy other's works, usually summarized under the term "fair use".
More interesting is the other case. I think copyright terms are now ridiculously long. After all, all new works rest heavily on the public domain of our shared culture - from obvious cases like Cinderella (lifted from an ancient fairy tale) to modern art like John Cage's 4â33â that is completely meaningless without the cultural background. It is only fair that new works also enter this pool after a reasonable number of years.
Currently, media companies are pushing for even longer copyrights, and for additional restrictions like the DMCA that circumvent many of the traditional fair use rights (what good is the right to sample a DVD for critical commentary if I cannot play it in my country due to region coding and can't work around it due to DMCA-like laws?). The Pirate Bay simply is pushing back.
The real problem is that media companies used to make their money via control of the distribution channel, not via the creation of new material. Despite claims to the contrary, you and I really used to pay for little silver plastic discs, not for "a license to listen". With the internet, they have lost effective control of the distribution channel. Copying is cheap, easy, widespread, and often even gives you a superior product. What we currently see is the dust from this disruptions slowly settling...
For my application (proof search in first-order logic), I need nearly exclusively integer performance, not flops. I also have extremely well-behaved parallelism - each processor gets an individual work package (typically a few kB of input), and chews on it for minutes, producing a summary of less than one kB. So I don't need a high-performance network, either. NUMA is not an issue, as every task works locally. On the other hand, multicore processors have given me very unreliable results, as the application is very memory access intensive, and contention between two processes on the same CPU is non-deterministic. For Core-2 processors, running two jobs at the same time throws off my measurements of cpu time by 20-30 percent.
On the other hand, Marvel expects to get the wall wart down to US$49,- and it only uses 5 watts. I'm interested in integer MIPS/watt and integer MIPS/$, and I think the wart is attractive there.
That's just normal behavior for any reasonably modern Unixy kernel. You don't waste resources by keeping a large pool of "free" memory around. Instead, you have large buffers and keep disk-backed pages swapped in until you need the memory, and only then reclaim them. "946799(0) pageins" means you are not currently swapping, and with the 4k page size of the Mac, it means that you have only ever loaded 3.7 GB from disk, and swapped out 1.2. Unless your machine has just been rebooted, this is not a sign of lack of memory.
Sorry, but Americans need not apply for "worst drivers". I've been in at least two of the "worst" cities in the US (Boston and Miami), and none of these came close to the average European city. And after I went through Paris in a car driven by a German who spent the last 6 months in Cairo, I do have a fairly high measure for people who want to beat that...
Ack, you probably were referring to having 1 Gig of RAM on board and not extra storage.
Yep. 512 MB of flash disk is plenty if all you need is a bit of Python, ssh, and a 200 kB executable. But 512 MB RAM is on the low side if you cannot reasonably swap.
No joke. If they come out with a Gig of memory, I'll buy 20 or so and set up my own compute farm. I'd really like to get my hand on a sample and a cross-compiler to see what 1.2 GHz ARM means for my application...
If you want to stretch their minds, Gödel, Escher, Bach by Douglas Hofstadter is excellent. It's much deeper than it may seems, so it needs some support from a teacher who knows what he or she is doing.
If you want to make their first year in college much easier, have them work trough Schaum's Outline of Linear Algebra by Seymour Lipschutz. It's the best introduction to LA I've ever seen, accessible, but without dumbing things down.
However, tasks that can be completed with an iterative polynomial-time algorithm often end up exponential when recursive. Of course, a bit of tail recursion and you can deal with that, but some things aren't easily tail recursed.
That is not so. Recursion is more general that iteration, and if you make use of that extra expressive power, you can get higher-complexity algorithms. But then these algorithms would be just as complex if implemented with iteration and an explicit stack, or whatever data structure is needed.
The canonical example where iteration is linear and naive recursion is exponential is the computation of the Fibonacci series. But the simple iterative algorithm is by no means obvious - or, on the other hand, a linear-time recursive algorithm is not significantly harder to come up with.
Problems that are not easily tail-recursive are also not easily solved with simple iteration.
This very much depends on the university. For the two (German) universities I'm most familiar with, Students have normal copyright in all work they create. They may, however, have only a shared copyright, depending on how much guidance and support they had from their supervisor/lecturer. The university reserves an unlimited license for scientific use of the work.
Please note that public universities in Germany are either free or charge a nominal fee only (typically not more than EUR 1000/year).
Say, that word, nazi, what does it mean again ? Oh right... it translates to "socialist".
No, it does not. It translates as "National Socialism". It's about as socialistic as the Democratic People's Republic of Korea is democratic.
Transferring ownership of means of production exclusively to the state and then creating "social justice", the central part of the nazi policy, what's that according to you ?
..except that the Nazis did not transfer the ownership of themeans of production exclusively to the state, which is why companies like IG Farben or Krupp made record profits.
Hitler was a fucking nobel peace prize laureate due to a leftist "professor", with a questionable past.
Strike three. You are out. No, Hitler was not a Nobel peace prize laureate. He was apparently nominated, but the nomination was withdrawn even before it could have been rejected.
No, there is no sustainable water supply. Even today, pumping removes much more water from the aquifer than is recharged, and several bores are already dry due to sinking pressure.
Because volcanoes put more carbon into the air that humans will in our entire existence on this earth.
That's nonsense. CO2 emissions by volcanoes (including those underwater) are less than 1% of current anthropogenic emissions. There is no serious doubt that the recent (during the last 150 or so years) increase in atmospheric CO2 is primarily due to the burning of fossil fuels. Simple mass balance shows that we emit about twice the amount of CO2 needed to explain the increase (the rest vanishes into natural sinks, mostly the oceans), and isotopic analysis shows that the carbon in that extra CO2 is of fossil origin.
I can understand being skeptical about global warming, but what I cannot understand is blatant ignorance about the basic facts
Sorry, but "highly critical solutions" and "Windows" does not really go together.
You don't seem to be heard of "Project Managers" in all their variety...
Actually, I am a project manager in one of its various forms, and I do development of safety-related systems. We currently use RHEL5 on the servers, and uLinux on embedded devices. No-one in our industry would use Windows except as a platform for writing documentation (and I hate it for that task;-).

The AAAS publishes the Science journal which has a distinctly liberal bias.
I would be interested to know how you arrive at that conclusion - any sources? Compared to what, exactly? Nature? PNAS?
