Re:Don't take freedom for granted
Last I checked we had a right to life, liberty, and the pursuit of happiness. A kid with down syndrome would die rather early without help, I would say that is denying him the right to life and most certainly liberty since he inherently has to rely on others until he can come into his own for the most part. That's also just one use of social security.
How is the concept behind graduated rates arbitrary. Are you disputing that it is not easier for someone making a few million a year to pay 35% than it is for someone making 38k paying 18%? I would be interested in how you arrive at that conclusion. This is not anymore tyranny than taxes are in general. You are benefiting more from society so you should have to pay more back to society.
Just from your posts that you referenced again and again which don't actually define socialism, they only demonize it with a libertarian slant that the strong should survive like they have over the last couple billion years. Libertarians often forget that when 38k a year people struggle to pay rent they quite often turn to crime as you can see with the sizable increase in crime-rates of late. Don't take my word for it. CNN Source.
It is the same all over the world, when people are desperate they take desperate measures and that isn't good for anybody including the rich.
I don't see another method of fair distribution, wealthy people can't get that way on their own, they have to rely on public funds in one way or another whether it be through roads, telecomm, or power infrastructure which was all publicly funded while it got off the ground.
Socialism is not a dirty word nor a dirty concept, as long as it is applied appropriately it serves the vast majority of people's interests. As you like to keep saying, you give up a little liberty so that there isn't chaos.
Here is some more material. more evidence.
So you agree that police and fire are necessary evils to prevent chaos but you ignore that financial causes of the crime that needs to be prevented. They are intrinsically linked.
I also think you need to read the comments on your graph more carefully as they state why those numbers are misleading. No one was disputing that the rich put more dollars into the pot but those graphs don't add up. The author himself contradicts himself with his graphs. He presents different numbers with the same title and then his other graph shows that the bottom bracket pay 96.93% while the top bracket pays 39.38%
I find that whole page very poorly written.

School teachers should record children questions
Everyday school teachers should record children questions and disclose them in school notice boards or in a website.
This will enhance intrinsic motivation of school children. -
Should record all WHY and HOW questions from Kids
As per the scientific research there is no such thing as intrinsic motivation.

Hence it is imperative to solicit why and how type of questions from Kids whether they sound rational or not.
All high school teachers across the private and public schools should record these questions everyday from Kids and display them in school notice boards or their websites. -

Re:Recycling sucks!
If you're going to make a controversial statement like the energy cost of recycling is higher than disposing, please back it up with references.
Here's something I found about the energy benefits of recycling. From http://ohioline.osu.edu/cd-fact/0108.html.
"Energy
Recycling aluminum requires 95 percent less energy than producing aluminum from bauxite ore. Making paper from recycled stock requires 64 percent less energy than using wood pulp. Containers made from recycled plastic save up to 60 percent of the energy required to make the same product from virgin material. Recycled ferrous scrap consumes 75 percent less energy than new ore. Virtually every material recycled uses less energy than using virgin materials. How much energy is this? Using and discarding just two aluminum cans in one day uses more energy than is used daily by each of a billion people in less developed countries. The average saving, however, does not include added energy costs of collection and transportation. "

Re:She will.
"Blah-blah, CO2 is good for plant growth, blah-blah, things will be better than ever before..." The problem is that plants need more than CO2 to grow, like minerals, nitrogen and water. IOW, increased CO2 will just sap up those resources even faster. Not to mention that "Nutritional quality declines because while the plants produce more seeds under higher CO2 levels, the seeds contain less nitrogen."

Re:Not So Funny: Threshold of Renewable Resources
Nuclear waste blather? Launch it all at the sun??
Yes, let's take all these tons and tons of radioactive material, pack it on top of some of the most efficient chemical explosives known to mankind, and elevate it into the atmosphere's global air currents. Paging the what-could-possibly-go-wrong department....
Okay, even disregarding this point, you and most people in this thread seem to be operating under a very common misconception about what "nuclear waste" is and the nuclear power industry as a whole. Most people will think of spent nuclear fuel as nuclear waste, when in fact there are many more kinds. The most often overlooked, and by far the largest source of volume in nuclear waste, is so-called "low-level waste," and is a very important window of insight into what actually goes on in a nuclear plant in reality.
From wikipedia: "Low-level waste (LLW) is a term used to describe nuclear waste that does not fit into the categorical definitions for high-level waste (HLW), spent nuclear fuel (SNF), transuranic waste (TRU), or certain byproduct materials known as 11e(2) wastes, such as uranium mill tailings."
To put this into plain English, this usually consists of everything that has been exposed to radiation in the course of a nuclear plant's facilities. "Nuclear waste" isn't just spent fuel rods. It's hammers, it's protective suit coverings, it's old pipes that have had to be replaced. There is a --huge-- volume of things that get contaminated by radiation in a plant. More information than you could ever use on this subject is found here Just to launch the low level nuclear waste alone in the state of Ohio alone (generated by only two nuclear reactors mind you) in the year of 1987 alone would require launching a satellite holding 50,000 cubic feet of material into space.
The simple fact is that in a nuclear power plant, radiation is --everywhere-- and it, to some degree or another, infects --everything--.
On an anecdotal note, of my family's grandfathers worked in the Pilgrim Power plant in Massachusetts for decades. He doesn't talk about his time at the nuclear plant much, even though it comprises pretty much all if his adult life. As more and more of his friends started dying of cancer, he just stopped mentioning it at all. While this is melodramatic, it's true: it reminds me in an uncanny fashion of how several other family members do not talk about their time in Vietnam.
The few things he did say gave me an insight into the nuclear industry that is very different from anything that shows up in G.W.'s nuclear power proposals.
He told me about how whenever he was working, he had to wear what he called a "dosometer." It was shaped like a security badge, and it changed color as it was continuously exposed to radiation, which was always present in some level at the plant. After a certain threshhold of accumulated radiation deemed "dangerous" was reached, the employee was supposed to stop working. Sometimes due to fiscal and work pressures, they just got a new tag. I'm sure safety procedures might be somewhat better nowadays, but humans are humans, and corners will always be cut on some level, by both management and by the employees, especially as economic times get harder.
While he has lived to a ripe old age, literally every one of his friends from the plant died a horrible death due to every type of cancer imaginable. "Incidents" like Three Mile Island and Chernobyl grab the headlines, but the nuclear industry kills each and every day in a way that is incredibly hard to quantify.
So, please. This "magic uranium" stuff is wishful thinking at best. If nuclear power truly is the only solution until humanity hypothetically masters fusion, that is a truly depressing option.

Re:So now we have thehttp://researchnews.osu.edu/archive/co2plant.htm
Crops have higher yields when more CO2 is available, even if growing conditions arenâ(TM)t perfect.
"But there's a tradeoff between quantity and quality. While crops may be more productive, the resulting produce will be of lower nutritional quality."
"Wild plants are constrained by what they can do with increased CO2. They may use it for survival and defense rather than to boost reproduction."
Nutritional quality declines because while the plants produce more seeds under higher CO2 levels, the seeds contain less nitrogen.
"The quality of the food produced by the plant decreases, so you've got to eat more of it to get the same benefits," Curtis said. "Nitrogen is a critical component for building protein in animals, and much of the grain grown in the United States is fed to livestock.

Re:Simple Math
SO the amount in the air goes up.
And plants everywhere are happy. There are studies that show that increased atmospheric CO2 is sequestered more quickly by plants. After all, if you eat more burgers you're bound to get fat. Feed the plants more CO2 (while avoiding toxic levels), and they will find a way to use it. -

Re:Fewest Users = Fewest Flaws
Among the Vista *features* I've found the most annoying, is this: At some point, not exactly sure when, or why it happens, but Vista will completely quit playing any and all media files in any media application. A search for trying to fix this problem will just tell you to get codecs. However, at the same time this occurs, one may notice that their network connectivity icon in the systray has a little red x over it even though you are connected. Any attempts to bring up network devices through the start menu or by right clicking on the icon usually will result in a long delay before any network options are presented to you. (It may appear that it is frozen, but given enough time, it will come up). Researching this problem led me to discover that in order to fix this problem I need to type "net localgroup Administrators

!Dynamic walkingI'm a bastard for nit-picking, but that doesn't look like dynamic walking.
To be precise, a robot walks dynamically if its center of gravity extends beyond the boundaries of its support polygon while walking. Take a look at the robot I work on to see dynamic walking. The difference lies in what happens if all the joints suddenly locked up completely while walking. A robot that actually walks dynamically would almost certainly fall over. Asimo and this robot would not. This appears to be the static or quasi-static situation described in the second link. -

Re:Matter knowing it's own existence>>Now look back at Europe in the middle ages, just handfulls of generations ago when humans were about 80% of our current average height.
Uh? It seems as if you're suggesting that these guys were different from us, only the living conditions (and the lack of medical knowledge) made them smaller for example, otherwise they were 100% identical to us. This is a very fine line to cut. Height is not a well understood factor in human genetic drift over the last millennium. Certainly some groups of humans have varied in height dramatically over the past thousand years, both becoming taller and shorter. See Men From Early Middle Ages Were Nearly As Tall As Modern People. Each generation applies unique pressures to its populations, and it would take many generations of a consistent pressure (or a species-threatening event) to permanently alter the genetic makeup of a species, but drift happens every generation. One generation might be taller (say, because food supplies needed for larger people are plentiful). The next shorter (perhaps due to famine, where the tallest will die first, needing more food). If these forcers were permanent (at least when measured on the scale of a millennium or so), then you might see the genetic markers for the less successful types of human completely disappear from the species. This is how evolution happens. It's not a straight-line between fish and man, but a slow, halting process of minor changes, most of which are reversed. It's one step forward, two steps back, with thousands of branch-points that lead to dead-ends or other species. -
Clickers
The physics department at my university has started using "clickers." They are small handheld devices resembling calculators that students can use to wirelessly answer multiple-choice questions an instructor poses via e.g. a slide on a presentation. After everyone answers the question and the timer ticks down to zero, the instructor can display a histogram of counts/answer.
Individual devices are tied to students in that only one id number is allowed per device, so these are also useful for taking attendence in large classes. Students enter their id upon connecting to the instructor's master node at the beginning of the class. Their utility for teaching depends largely on the questions the instructor asks, of course. If two answers receive similar amounts of support from students, individuals could be called on to explain their reasoning, helping the instructor to highlight where their weaknesses in understanding lie.
The devices are sort of a mixed blessing. I found that the best problems for them were those with two very similar answers that differed only conceptually, rather than mathematically.
Here's a link to one kind of clicker that's being used this semester (XP software via Parallels on OS X :) http://telr.osu.edu/clickers/ (I am not affiliated with OSU at this time) -

Re:In theory, the CO2 is recycled
The rest die off in at most a few years, and decay pretty quickly.
Bingo! What do you think is trapped in decayed plant matter? Hydrocarbons.
No, I understand the biology completely. Unfortunately, you appear to be looking at this through an ideological lens. Plus you don't seem to understand where that 'soil-produced' CO2 comes from.
No, you're still missing my point. Fallow land looks like this:
CO2 -> live plant -> dead plant -> soil organic matter
This goes on for hundreds of years. Lots of carbon builds up in the ground that way. Sometimes that carbon gets buried for millions of years turning it into fossil fuels:
soil organic matter -> buried millions of years -> fossil fuels
You are complaining about the combustion of fossil fuels because it releases CO2:
fossil fuels -> oxidation -> CO2
Plowing exposes soil organic matter to natural weathering which results in erosion/oxidation and releases CO2 back into the atmosphere. Therefore, a plan to take land not currently in crop production to grow corn for bio-fuels looks like this:
soil organic matter -> oxidation -> CO2Look familiar? I'm not talking about the CO2 that is in the air that you plan to recycle. I'm talking about the CO2 already captured in the ground where it will stay until you start your plows. Putting more land into crop production will release that CO2. You're essentially burning tons of fossil fuels before they become fossil fuels.
Besides that elementary fact about the carbon cycle... Keep in mind that farmers use lots of lime to raise the pH of acidic soils rich in organic matter.... CaCO3 + H -> Ca + OH + CO2. Then there's nitrogen fertilizer, used abundantly in corn production... yielding acid rain, smog, holes in the ozone, and greenhouse gases. Hooray!!
The sequestered carbon becomes fossil fuels.
Not if you oxidize it before it gets there.
Releasing that carbon is what upsets the balance and leads to a net increase in CO2 level.
And that's exactly what will happen with this retarded corn bio-fuel scheme. Releasing billions of tons of sequestered carbon that lived happily as soil organic matter until you decided to plow land it was trapped in. I'll assure you the people advocating this scheme know this. They only care about themselves and their corn prices. Starving people be damned, lets burn food!
If you really cared and wanted to reduce CO2, you'd be advocating no till farming. Maybe algae based bio-fuels would accomplish the goal of reducing CO2. Personally, I don't see CO2 as a problem, but if you do, you should at least know that this scheme is a really bad idea on a number of different levels. Sorry if any of this sounded condescending, but having to explain this stuff over and over again to people who've been misled by the talking heads isn't very rewarding. Don't let people with hidden agendas (Bush, realclimate.org, etc) lead you around by the nose.

Gary Demos, John Whitney, james Blinn, TRON,
I was a classmate of Gary Demos at Caltech. Through him I met John Whitney Jr.,and John Whitney, Sr. I've got to point out that Demos and Whitney, Jr., played a key role in the history of CGI, including on TRON. John Whitney, Sr. is the father of computers in film animation, going back to analog computers in the 1950s; he also invented the credit crawl technique from the opening of Star Wars (30 years old today).
To excerpt from
http://accad.osu.edu/~waynec/history/timeline.html
While at CalTech, Gary Demos was made aware of the work of John Whitney, Sr. who was teaching classes there, experimenting with early CG images. Whitney's work, and that of the University of Utah, prompted Demos in 1972 to go to work for Evans and Sutherland. E&S used DEC PDP-11 computers along with custom E&S hardware, including the Picture System and a variation of the UofU frame buffer. At E&S, Demos began discussions about filmmaking with Ivan Sutherland, and together they started a company in LA called the Picture/Design Group. Demos met John Whitney Jr. at P/DG, and they started to work on some joint projects with Information International, Inc. Founded in 1962, III was in the business of creating digital scanners and other image processing equipment. Jim Blinn developed software (TRANEW) for III, which ran on a modified DEC 10, called the Foonly F1, which came out of the Stanford Research group and was originally used for OCR.
The III graphics effort was founded as Motion Pictures Product Group by Whitney and Demos (with Art Durinski, Tom McMahon, and Karol Brandt) in 1974. Early software was written by Blinn, Frank Crow, Craig Reynolds, and Larry Malone.They did some early film tests and broadcast graphics work for the European market. Motion picture work included TRON, Futureworld, Westworld, and Looker. They also produced Adam Powers, the Juggler as a demo of their capabilities. They marketed their services as "Digital Scene Simulation", and did several spots for Mercedes ABC and KCET. III hired Richard Taylor, an art director at Robert Abel, to handle the creative director efforts there. He brought a sense of film production to III, which in his words were lacking. He directed "Adam Powers" and was assigned as the effects supervisor for TRON (III produced the MCP, the Solar Sailor, and Sark's Carrier). Other projects included tests for Close Encounters, Star Wars, The Black Hole and the Empire Strikes Back, a stereo production called Magic Journeys, and many groundbreaking television promotion sequences.
Although they defined much of the early commercial perception of CGI, disputes regarding the computing power necessary to continue in the business prompted Whitney and Demos to leave to establish Digital Productions in 1982. They departed before TRON was completed, so much of the III contract was taken up by MAGI. Richard Taylor continued to handle the effects supervision, and was hired by MAGI when the film wrapped.
Gary Demos and John Whitney, Jr. went on to Digital Productions and then Whitney/Demos, and Demos more recently founded DemoGraFX (which was acquired by Dolby Laboratories in 2003), where he worked with digital TV, HDTV standards, digital compositing, and other high technology graphics related projects. Whitney founded USAnimation, which later became Virtual Magic Animation, in 1992. Demos and Whitney received the Academy of Motion Picture Arts and Sciences' Scientific and Engineering Award for the Photo Realistic Simulation Of Motion Picture Photography By Means of Computer Generated Images in 1984 for work on the movies "The Last Starfighter" and on "2010" using the Cray XMP. Demos also received an Academy Scientific and Engineering Award in 1995 for Pioneering Work In Digital Film Scanning", and an Academy Technical Achievement Award in 1996 for Pioneering Work In Digital Film Compositing Systems.

Re:isp's crying about having to provide what they
Students pay a small fraction of the highly subsidized costs of their education - tuition, facilities, infrastructure, salaries - at a TAXPAYER funded public institution such as Ohio University.
You have no idea what the hell you're talking about. Of Ohio State's $3.76 billion 2006/2007 budget, only $510 million (13.5%) came from state appropriations.
Considerably more money ($921 million / 24.5%) came from students. And even more than that came from the hospital that Ohio State operates.
Is this information hard to find? No! It's right on the Ohio State site, right here.
The fact is, at Ohio State, students funding is twice as big a factor as state funding. And student funding isn't a "small fraction" - it's nearly a quarter of the entire budget.
I go to a "state funded" school (University of Colorado at Boulder), but Colorado only contributes 8.1% of the funding for my university. Student fees and tuition contribute 39% of the budget - almost five times as much as state funding.
I am so sick and tired about this "what are my tax dollars doing" bullshit with regards to educational institutions. There are 26,000 people who attend my university. That's larger than most of the cities in Wyoming.
If a city offered municipal internet access (as many Slashdot users would like), would it be OK if the city decided that you shouldn't be allowed to use? What if the city prevented other providers from offering services on their premises?And I assure you, the taxpayers of Ohio have much better things to do with their money than to foot enormous bandwidth bills so that students can illegally download copyrighted music, movies, and porn faster.
Here we go again. Because, if someone is using BitTorrent, they must be a dirty criminal. Give me a break. There are so many legitimite uses for P2P that it's not even funny. I downloaded an Ubuntu CD when 7.04 came out using BitTorrent. Public domain and educational materials - including videos - are distributed with BitTorrent. There are even professors on campus who use BitTorrent to distribute video lectures.
Maybe you are too short-sighted to see the many uses of P2P technology. Guess what? The vast majority of email sent today is spam. That doesn't mean that email isn't a valuable tool.
I remember when Bill Owens made an incredibly stupid statement about how CU should dismiss a particular professor. Owens didn't seem to understand that universities have a large degree of autonomy - it's not the Governor who selects the Regents, it's the voters. If you don't like what's happening at Ohio State, elect different representatives. But don't go pretending that the State legislature should make policy decisions. Ohio doesn't like it when the Federal Government decides to interfere. Your City Council doesn't like it when the State interferes. -

Re:Is this a surprise to you, or are you just jokiI was already familiar with the Wikipedia cite, what other papers did you refer to? Right after my Wikipedia link, I said "See in particular, Foukal et al. (2006) and Stott et al. (2003)." The full references:
P. Foukal, C. Fröhlich, H. Spruit, and T. M. L. Wigley, "Variations in solar luminosity and their effect on the Earth's climate", Nature 443, 161 (2006) (link)
P. A. Stott, G. S. Jones, and J. F. B. Mitchell, "Do models underestimate the solar contribution to recent climate change?", Journal of Climate 16, 4079 (2003) (link) You say the CO2 emissions correlate with global temp curves, did they cause the Medieval Warming Period or Holocene?
No. I have not claimed that CO2 emissions are the only factor that influences global temperature, nor have I claimed that the Sun does not affect global temperature. What I claimed is that solar variations cannot account for the majority of the recent (last 50+ years) warming. Other than solar activity, the only explanation for the extraordinary Holocene warming is a recent (1999) theory that the Earth's tilt may have changed for a couple thousand years. That theory is based on a model, there's no evidence as of yet. As soon as you try to translate "sunspot number" into "warming", that too is based on a model, and there's even less evidence of that than there is for orbital forcings, although there is some evidence that some localized coolings during the Holocene were due to reductions in insolation. Possibly, except that the Earth's history shows the global climate has little sensitivity to CO2 levels. It is impossible to predict absolute global temperatures from absolute CO2 levels alone; you have to know what all the other forcings are doing; paleo data that far back doesn't tell you anything about the climate sensitivity. You can do better predicting changes in temperature from changes in CO2 levels, but even that is not very useful given the sparsity of the data on million-year timescales. Changes in CO2 levels and changes in temperatures do correlate well in the finer-grained data over the last few hundred thousand years (e.g. the Vostok ice cores). And CO2 is in fact implicated even in far-past climate changes, such as the Ordovician cool period you mention (see here). Finally, there have only been three periods during which temps have been as low as they are today, and the other two took place during mass extinctions (Ordovician and Permian). Your point? Also, the Permian extinction period is the only other time when CO2 levels have been as low. Again, your point? Are you trying to draw some relationship between CO2 levels and mass extinctions? If so, what?
Just another coincidence? Or proof that we're in an unstable period of cooling and the Earth's climate is eventually going to get warmer no matter what we do. The Earth's climate may get warmer "no matter what we do" on million year time scales, but the majority of the warming that has been happening recently is due mostly to us, and currently far outweighs much more gradual climate trends (which have been towards cooling, not warming, over the last 5000-8000 years).
Attributing global warming to "natural cycles" both disagrees with the nature of those cycles and ignores the existence of the greenhouse effect. certainly there haven't been runaway greenhouse effects that the current models would lead us to expect What "runaway greenhouse effects" do you believe current models lead us to expect? -
Re:Yes besause...GP is simply asking for a bit more than speculation before making trillion dollar policy decisions. There is more than "speculation" on the matter, but there are still deep uncertainties regarding the extent and impact of future warming. The existence of current warming, and man's contribution to it, is not however in doubt.
Yet, CO2 was an order of magnitude higher 450 million years ago and temperatures were roughly the same as they are today. Climate isn't correlated with absolute concentrations of CO2, because of all of the other climate factors in effect. Changes in climate are correlated with changes in CO2, however. In fact, the Ordovician temperatures and CO2 concentrations to which you refer support our picture of the influence of CO2 on the climate, rather than contradicting it. The evidence suggests that a drop in CO2 precipitated the ice age, and a rise in CO2 may have ended it. CO2 concentrations are about 20% higher today than they have been any time in the last 400,000 years yet drastic temperature increases have not followed suit. They're not drastic on the scale of "an ending ice age", but they have produced an unusually rapid temperature change, temperature increases are related nonlinearly to CO2 concentration, and we are still in for a lot of CO2 increase over the next century, which is the real worry. In the mid 90's, Dr. Patrick Michaels called bullshit in front of Congress when predictions of higher temperatures made by computer models did not materialize. Micahels' analysis was, shall we say, dodgy at best. "climate scientists" once again were eating humble pie when computer models that generated gloom and doom "hockey stick" graphs were shown to spit out hockey sticks with random input by people who were not climate scientists McKitrick & McIntyre's analysis is also not without its flaws (here and here). -
What is the purpose of the class?
What are you trying to teach the students? If you get a bare microcontroller like a PIC then you quickly have to spend a lot of time teaching electronics so that the students know how to properly connect hardware to collect sensor data and drive motors. You end up explaining different communications protocols (what is this RS232-TTL chip for, what is SPI and I2C, etc.) which may or may not be the purpose of the class. If the purpose is to "build a robot that does task x" then you're better off getting a kit of some sort that has some built-in interfaces for sensor inputs and motor outputs. I've had many years of experience with the Handyboard and must suggest it has a good choice, though $200-250 may be a bit pricey to get started. Oregon State and Atmel have teamed up to produce a system for their EE curriculum that looks promising, though you would have to get in contact with them to see how you might be able to purchase their boards in bulk (they have a website you can order some parts from, base kit is $105). If you want to teach "this is how you program a robot" then you can pick up any programmable robotics set and get going quickly. For younger students that haven't programmed before something more graphical may be better for them (Mindstorms for example, though you don't seem to want this sort of thing). Any way you go you'll probably end up teaching teamwork skills (and you should probably throw in some documentation skills also). There is a freshman program developed around the Handyboard that teaches such skills at Ohio State (dislaimer: I was a TA for this program) which has quite a few materials you may find useful. In summary, make sure you decide on your curriculm, then pick a controller that best fits into both that and your budget.

What I have always wondered about...
The Chicxulub event, while large, is not the only large impact suffered in Earth's history. There are quite a number of large craters in the geologic history, and probably more that we have not stumbled upon yet. The Earth Impact Database lists two craters larger than Chicxulub:
http://www.unb.ca/passc/ImpactDatabase/CIDiameterS ort2.htm
Wikipedia blurbs on the two largest (as usual, do more research to verify if interested:)
http://en.wikipedia.org/wiki/Vredefort_crater
http://en.wikipedia.org/wiki/Sudbury_Basin
There are also questions about a possible crater in Antarctica, but it's too new an announcement to know if the features observed are actually impact related: http://researchnews.osu.edu/archive/erthboom.htm
My question is, why would the Chicxulub event have been so uniquely deadly?
I suppose one possible scenario is a double (or more) sucker punch of large impact followed by volcanic activity and/or other factors that happened to hit while the Earth was still recovering from the impact. Of course, that's a bit complex for a spectacular headline.
I hope work continues on this - it's a fascinating insight into our environment and might be useful in knowing how to safeguard ourselves against changes in the future. -

Er, that's THE Ohio State University, thank you very much.

Re:Any Irony Here?
.....That's the reason that Kyoto largely exempts developing economies.....
Kyoto is a farce designed to hobble western economies and give some an unfair advantage. If pollution is really bad and affects the entire planet, then it doesn't really matter where it is generated. Unlike many pollutants man generates, CO2 is a natural component of the atmosphere. Every time you exhale you add some.
Climate is subject to many variables, including solar output. There is evidence that human activity has had little if any effect on global climate in the past.
http://researchnews.osu.edu/archive/5200event.htm
There is nothing that says solar output may not oscillate again like it did 5200 years ago. There are two intriguing mentions in the Bible about a future time when there will be significantly increased solar output. (Isaiah 30:26, Revelation 16:8-9) People may scoff at these ancient writings, but neither can anyone unequivocally say this could never happen.
We humans did not make the earth nor the sun. We are incredibly arrogant creatures who think we can affect the work of the Creator in any material way. -
Re:What if it does? Seriously.
A lot of that I'm sure is safe, but I can't imagine that somewhere in there and among Microsoft's untold zillions of software patents that there isn't a (legally) reasonable case that could be made against something OSS that people would care about.
A good many GUI's existing before MS-Windows. Just as there are timelines which document how OS kernel's have evolved, there are also timelines which document how GUI's have evolved. This site documents the evolution of each and every GUI, along with every icon that each GUI has used. This is particularly important for commercial application developers who wish to avoid any lawsuits caused by using someone elses "trademarked" icon.
As an example, here is the components page, which documents the evolution of the most commonly used icons.
As long as the Linux community can prove that any feature in an application has prior art in earlier GUI's that haven't been patented or copyrighted by Microsoft, then it is pure Microsoft FUD. If MS want to sue Linux, then they will have to sue the other OS vendors as well. -

you undermine your own argument when you misinterpret statements like that.First off, the GP claimed that the fraud was on the order of "thousands of registrations", but the only places in which his article mentioned numbers were the 7 duplicates and 1 dead person, along with 4 people getting 2 counts of fraud-related indictments.

I agree that if an area has a history of problems with elections, I'd probably want to institute things like a mandatory recount in those areas so that you verify the accuracy of the results, but a history of illegal behaviour isnt itself evidence of criminal activity.

Districts that used systems that produced paper ballots would still be subject to recounts.
To an extent. The exact details of the recount statute and court ruling are complex, but it boils down to this:
o the only time a county can initiate any recount is if the totals are within one-half of one percent of votes cast
o even then, a manual recount may not be ordered if the number of overvotes, undervotes, and provisional ballots is fewer than the number of votes needed to change the outcome of the election
o in the unlikely event that a recount does occur, the first recount must be done electronically, either by re-printing the results from the touchscreens or by re-running the ballots through a scanner
o after the initial "recount", the only way they can move onto a manual recount is if the new totals are within one-quarter of one percent of each other
