two bad choices
I have some insight on this topic as a university professor. I've used both systems, and I was on the Academic Technology Committee when it was advising the CTO and CIO on purchasing decisions for such systems. We wound up paying for both. As you say, they both suck, and I'm sure whatever unholy combination is produced will suck even worse. At the time - 1999 or 2000 I believe - "open source" was something my colleagues on the committee had heard of but didn't know anything about, and the CTO and CIO were computer-savvy but looked on open source with disdain (this made sense as they were constantly wined and dined by folks who represent closed source companies looking for big deals). I was teaching summers at UCLA at the time and had the opportunity to use ClassWeb, an open source alternative to such tools. My experience with the tool was exemplary; I thought it was easy to use, it fulfilled the necessary functions and was not needlessly confusing for students. It was also free. Best of all, the developer worked at UCLA so when there were features I wanted I was able to ask him for them and they were available in days. It was truly a classic case of the superiority of the open source model working well. For much less the price we paid for Blackboard and CT, which all the students complain about, we could have hired programmers to handle coding issues on classweb and had an open source solution that we could fine tune at will. But when I made the suggestion, the feeling around the table (particularly from the CTO and CIO) was, shut up hippie.... Today I don't use any such tools -- I still code my course web pages by hand using html and have some very primitive open source discussion board technology for discussions. I think it's necessary to have courses online these days for various reasons, but the tools offered by these companies are needlessly ornate and confusing. The open source model makes sense in general but especially in public university settings where costs are a relevant factor and where the freedom to tinker with code brings with it additional educational benefits.

Re:An honest question...
How do we know the universe is 13.7 billion years old? It was recently discovered that the universe's expansion is accelerating as time goes by. Assuming this change in acceleration has been the case all along, doesn't that really fudge with the numbers we used to estimate the universe's age?
There are many ways to estimate the age of the universe, not all of which involve calculating the expansion of the universe.

Heritability and environmental / developmental alteration of methylation and thus gene expression: Control of Gene Expression in Eukaryotes by Phillip McClean
http://www.cc.ndsu.nodak.edu/instruct/mcclean/plsc 431/geneexpress/eukaryex5.htm
http://www.ifgene.org/vines.htm"Bizarre things are going on that we are just beginning to get a handle on," says Marcus Pembrey, a clinical geneticist at the Institute of Child Health in London. Consider the pregnant Dutch women who starved during the famine of the Second World War. Not unexpectedly, they had small babies. Far more surprisingly, those babies went on to have small babies, even though the postwar generation was well fed and no genes had been tinkered with.

Cotton tree eh?
Well if you like being naked!
Among Bombacaceae, the most famous economically important fruit hair has been harvested from Ceiba pentandra, the kapok or silk-cotton tree. Probably few people in California have ever heard of kapok, a towering emergent of lowland neotropical forests, often reaching fifty meters in height and forming enormous, flaring root buttresses that prevent the tree from snapping at the base. Unlike cotton, kapok cannot be woven into cloth, but formerly it was widely used for stuffing pillows, bases and balls for baseball and softball, mattresses, and, especially, life jackets. In fact, during World War II, a U.S. sailor would commonly refer to his life jacket as a "kapok." Since the war, however, synthetic fibers have replaced kapok for these traditional uses.

MSWord & Storing Negative Information & An
The Fine Article doesn't mention one exciting development in the field of information theory, related to negative information, which may one day tie it to Vacuum Energy or Zero Point physics in a grand unified theory that, once we come to understand it, could form the basis of a star drive to power star ships.
It seems that virtual particles of antimatter and exotic particles of normal matter that spontaneously emerge from the void, and then disappear without interacting with anything. [1] The theoretical potential of tapping this particle flux has brought vacuum energy to the fore of research by the NSA into Quantum Information Theory.
Experiments conducted by the NSA and the DOE on large data samples gathered in large bureaucracies (both public and private) indicate that Microsoft Word Documents are effective containers for Negative Information, which hitherto had been considered a transient phenomenon, almost impossible to store given our current understanding of physics. The phenomenon of massive amounts of stored negative informisinformation, as it turns out, makes the typical corporate or government intranet much more resiliant to cyber terrorist attack than previously predicted -- nearly as resiliant as the typical government organization to a FOIA request today, for comparison.
It is expected that once we understand the characteristics of MS Word Documents which allow them to efficiently store negative information in a stable form, Quantum Physicists and Information Theorists should be able to get together, perhaps over a nice hot cup of tea, and stitch the two branches together, getting us one step closer to faster than light travel, finally bringing the stars within reach -- except it won't really be FTL, it will be something that we don't presently understand.

OS Bioinformatics software
Most useful open source bioinformatics software is going to be geared toward biologists with at least some programming and unix skills. A lot of it was written by bioinformaticians which tend to lean more toward the informatics than the bio. They get more caught up in the technical aspects of the feild rather than the biology of the problem looking to be addressed. Unfortunately, the same can be said about most commercial bioinformatics software as well.
On the flip side, when people more interested in the biology than the technology write software, they tend to write just enough to get the job done and then stop. Software from this camp is often buggy and has a bad UI or no UI at all. It gets the job done, but only if you know exactly how to use it.
Anyway, you might want to take a look at R - http://cran.stat.ucla.edu/. It's more geared towards statistics but it does have some protein modules. -

Unfortunately in current US law, the mere circumvention of a "copy protection" mechanism by the end user is illegal, whether your doing so violates ordinary copyright or not. There are exceptions made for libraries and research institutions, but not for ordinary end users.

Re:CNN is apparently in the midst of a new plan...
And before anyone complains, you may be interested in at least considering:
http://www.polisci.ucla.edu/faculty/groseclose/Med ia.Bias.8.htm [ucla.edu]
which finds, in part
Our results show a very significant liberal bias.
Of course, this study has deep methodological problems that have been discussed to death in the statistical reporting community (See, e.g., Measuring Media Bias, Michael Cardwell, George Mason University, March 1, 2005). The consensus seems to be that the studied media outlets trail their consumer's tendencies in this area--that is, consumers do not, in fact, demand objective coverage, but rather demand coverage skewed to match their views, and media outlets tailor their product to consumer demands. And that changes in consumer bias precede (and drive) changes in media bias.
One of the major findings is that the American people are by and large more liberal than the members of Congress (in large part because conservatives tend to vote more than liberals, possibly because of age correlations), so comparisons to members of Congress don't tell you whether the media is skewed relative to the general population--and, in fact, it appears that it is not.
The second upshot is that, since the general population's conservative/liberal leanings are farther to the left than a study of members of Congress would show, it turns out that not only is the media on the whole in line with the public's stance, but that the New York Times is far closer in line with the public's beliefs than is Fox News.
Note that none of this is meant as a vindication of any journalistic integrity or objectivity; on the contrary, it seems to be basically a result of the media outlets following the dollar and trying to present the news as people want to hear it.

CNN is apparently in the midst of a new plan...
...to win viewers/readers from FOX News. There's a Newsweek piece about it this week.
[CNN president Jonathan] Klein is making revolutionary changes at the cable network--scrapping signature broadcasts like "Crossfire" and "Inside Politics," shaking up his morning-show ensemble and his prime-time producing staff, and creating a new international news show at noon. These are only the first steps in a broad overhaul plan aimed at getting the pioneering and once dominant cable news network out of a seemingly perennial second-place finish, far behind Fox News.
And before anyone complains, you may be interested in at least considering:
http://www.polisci.ucla.edu/faculty/groseclose/Med ia.Bias.8.htm
which finds, in part
Our results show a very significant liberal bias. All of the news outlets except Fox News Special Report received a score to the left of the average member of Congress. Moreover, by one of our measures all but three of these media outlets (Special Report, the Drudge Report, and ABCs World News Tonight) were closer to the average Democrat in Congress than to the median member of the House of Representatives. One of our measures found that the Drudge Report is the most centrist of all media outlets in our sample. Our other measure found that Fox News Special Report is the most centrist.
and
Based on sentences as the level of observation (the results of which are listed in Table 8), the Drudge Report is the most centrist, Fox News Special Report is second, ABC World News Tonight is third, and CBS Evening is last.
Given that the conventional wisdom is that the Drudge Report and Fox News are conservative news outlets, this ordering might be surprising. Perhaps more surprising is the degree to which the mainstream press is liberal. The results of Table 8 show that the Los Angeles Times, the New York Times, USA Today, and CBS Evening News are not only liberal, they are closer to the average Democrat in Congress (who has a score of 74.1) than they are to the median of the whole House (who has a score of 39.0). [...] the New York Times is twice as far from the center as Fox News Special Report, to gain a balanced perspective, one would need to spend twice as much time watching Special Report as he or she spends reading the New York Times. [...] Our results contrast strongly with the prior expectations of many others. It is easy to find quotes from prominent journalists and academics who claim that there is no systematic bias among media outlets in the U.S. [...] The main conclusion of our paper is that our results simply reject such claims.
Please note:
These findings refer strictly to the news stories of the outlets. That is, we omitted editorials, book reviews, and letters to the editor from our sample. (emphasis mine)
It makes me sad when people can't tell the difference between NEWS and OP-ED. Do people also have that same problem with the editorial page of the New York Times? Or just, say, Sean Hannity on FOX News? Is it acceptable to judge the news gathering and reporting capability of the Times by exclusively evaluating the content of its opinion page?
Further, one of the prime measures this report uses is the scoring for members of Congress by Americans for Democratic Action (ADA), the self-described "nation's oldest liberal lobbying group".
Now, some might say that comparing news to members of Congress, be they Democrats or Republicans, isn't an effective measure (especially if you believe there is virtually no real difference between today's politicians). But at least take time to consider the report.

Re:At the risk of being off-topic...
In practice, no economically optimized dictatorship has ever existed
Some people in South Korea and Taiwan may say that this concept is not quite correct. Recent work titled "The Political Economy of Growth: Democracy and Human Capital" (PDF) shows that democracy has no statistically significant direct effect on economic growth.
There are plenty of examples of dictatorships which were highly effective in achieving economic growth, and plenty of examples of democracies which are not effective in achieving economic growth. Of course, the converse of both is true as well.
Economic growth has much more to do with regulation per se, as opposed to the political source of the regulation. -

Re:A big DUH on pragmatism ...
The most pragmatic thing would have been to KEEP the sanctions going and keep Saddam in his box. Less Americans would have died (1500 and counting) and less IRAQIS would have died (100,000) and counting.
If you look at it in a vacuum, sure.
But what about the approximately 600,000 Iraqis that died (according to various estimates by Amnesty International and Human Rights Watch) as a direct result of the sanctions process?
Now that sanctions are over, we have a hope at a quite significant net preservation of Iraqi life when compared to the egregiously abused UNOFP and sanctions process.
The REAL motives of the Iraq war was to acquire the Iraqi oil resources (it was the ONLY asset protected after the invasion)
As I said, but I'd say not so much "acquire the Iraqi oil resources" as "ensure that we have continued and future access to the oil resources in the entire mideast region as part of a comprehensive plan to reshape the state of governments in the mideast, and prevent a possible Panislamic empire that would desire the destruction of the US and the West".
and to create permanent bases with which to frighten and intimidate Iraq's Arab neighbors.
All in the eyes of the beholder, I guess - YES, to frighten and intimidate Iraq's non-US- and non-West-friendly neighbors! We want them shaking in their boots, and for reformers and modernists to rise up from within and demand change, for example, in places like Tehran.
Hey, I was FOR the war when it started. I parted from my liberal colleagues because I believe that Saddam was a threat. I didn't believe ANYTHING Bush said. I believed COLIN POWELL. Jeesh, he sure spoiled his credibility with me.
Since hundreds upon hundreds of tons of Iraq's WMD are unaccounted for to this very day, it wasn't beyond reason to expect to find WMD in Iraq. But even if we did find large caches of WMD in Iraq, that wouldn't have changed the fact that WMD is not the primary reason we went to Iraq, though it was initially the *stated* one.
The only acceptable reason for risking American lives is SAVING American lives. You seem to think this little Iraq excursion is protecting Americans.
Actually, I didn't say either, but on this topic, you're falling into the trap I see many succumb to: once again, looking at it as a vacuum:
1500 lives lost; that's 1500 lives that would have been saved had we not gone.
It's not that simple or black and white, man! I find this type of black and white reasoning astounding coming from people who usually denigrate that type of reasoning. Iraq, and the overall mideast strategy, is NOT A VACUUM.
MANY lives will be lost in this effort. The goal, however, is that, longer term (e.g., the next 50-75 years), many more lives will be spared, on BOTH sides.
Now, I understand the pragmatism of saying "you can't predict the future, but we KNOW that those 1500 would still be alive had we not gone, and we further know we would not be directly responsible for XX0,000 Iraqi deaths". Certainly I agree with that.
But what of the approximately 50,000-100,000 Iraqis/year who would have died due to inattention under sanctions (as had happened each one of the previous 12 years, according to liberal human rights watchdog organizations, meaning there was no reason to expect it to change)?
What about the Americans or other Westerners - say, in Europe - that may die from attacks due to the unchecked growth and increasing aggression of Panislamic terrorists?
I think you've been watching too much Fox News.

We control our own developmentEvolution acts on population gene pools when some factor favors the survival of specific genes. However, modern humans depend on genetics to a far smaller extent then any other species; rather, we depend on our intelligence. We don't evolve thicker fur or blubber to live in colder environments, we alter our environment (shelter) or create artificial means to warm ourselves. Synthetic transportation replaces wings or faster legs. We use medicine to cure ourselves of disease and accidents. It therefore seems both likely and acceptable that in the future, humans will choose to alter themselves at a physical, internal level. This seems to be a logical progression from our current external prosthetics, like cars. I suspect this will take the form of one or more of the following:
- Genetic engineering: Gene therapy is currently a very promising field of study, and research on vectors is finally yielding some extremely promising results, both for viral (see some of the fourth generation or higher lentiviral systems) and non-viral (liposomes etc). As gene therapy becomes common, the same techniques can be applied to not just fix genes, but add or alter existing ones to give desirable attributes (better vision, etc).
- Brain-computer interfaces: Once again, most current research takes place with the aim to provide superior prosthetics to people who have suffered from accidents. This is my personal area of interest. In principle, all the input and output going into the brain should be able to be intercepted and controlled. By doing that, a person could be transplanted into any artificial body desired. I feel that at the current pace of development, this will be a relatively (there is always risk with surgery) safe and well understood procedure within 20-30 years, assuming research isn't outlawed or anything like that.
- Medical nanotechnology: Very speculative, I don't think anyone knows for sure whether is can actually be done or not. I'm listing it because it would be a different way to augment the human body from the previous two.
All of these technologies may work together, of course. It may be that human genetic engineering would help a person be more compatible with synthetic augmentations, for example. I also believe these are all good things. The core of what makes us us is our minds, and it seems tragic that so many people are restricted by the box their brain must travel in. I hope to be able to help make it so that losing limbs and getting paralyzed are simply no longer problems that need to be worried about beyond some inconvenience. I think that transferring to artificial bodies, or at least advanced gene therapy, will be important for future efforts to colonize space. It appears that in many ways, the primary threat is luddites shutting the research down. Fortunately, so far most of this has passed under their radar, so I am hopeful that will continue to be the case until actual products are ready to go. At that point, it will be too late to stop it. It is an exciting time to be alive though, and I encourage everyone to go and do some research on the subject, especially if you have access to a college or corporate net that has subscriptions to primary research engines, like ScienceDirect or JStor. Also, everyone can look at becoming a member of the AAAS, which will get you online access to Science.

Summary of the actual nature article
Their setup: The 'crystal' mentioned in the mainstream articles, is a z-cut lithium tantalate crystal (LiTaO3), with the negative axis facing outward onto a hollow copper block. A tiny tungsten probe (80 microns long and 100 nm wide) is then attached to the other crystal face. This probe acts as a tiny mast for the electric field so that there is a powerful electrical field at the tip of the probe. Then there were a bunch of fancy neutron-counters and single-photon counters bundled around it.
What they did: First they added deuterium gas (at 0.7 Pa) and then cooled the crystal down using liquid nitrogen (to 240 K). Then they used a little heater to increase the chamber temperature slowly.
What happened: Less than 3 minutes later, and still below 273 K (0 degrees Celcius), the neutron signal rose above the background level. There were x-rays coming from the probe tip, and a whole bunch of neutrons. After a few more minutes, the electric field was so strong that it caused arcing between the probe tip and the enclosure (because they kept heatingthe crystal, and the field thus kept getting stronger). The arcing stopped the process (and I'd guess it damages the crystal?).
They added a few links in the article to previous papers: a pdf describing the concept they are trying to harness, another pdf with more about how they use the crystals with the deuterium gas, and a brief abstract.
I think this is pretty cool. I bet/hope that before long (within 10 years), this will be powering small extrasolar probes.
Pretty neat stuff. I don't even mind dupe posts when they're on such important stuff.

A UCLA collaboration (Seth Putterman, Brian Naranjo and Jim Gimzewski) appear to have developed a fusion device powered by a pyroelectric crystal, a type of crystal used in cell phones to filter signals. When heated, such a crystal produces a large electric charge on its surface. The UCLA researchers placed a lithium tantalate (LiTaO3) pyroelectric crystal so that one side touches a copper disc. A tiny tungsten probe is then placed at the center of the copper disc. When the crystal is subsequently heated, a very large large electric field is produced at the end of the tugsten tip, ~25 billion volts per meter. This field gradient is so high that it strips the electrons from nearby deuterium atoms. The ionized deuterium atoms then accelerated by this field towards a solid target of erbium deuteride (ErD2). They collide with it at such high energies that some fuse with the target. A measurement of almost 900 neutrons per second was observed. This is 400 times the background! Although the amount of energy produced in this initial experiment was miniscule (~1E-8 jules), this technology could be used for things like microthrusters. There are pictures and movies on the UCLA's physics site. Reader richmlpdx adds a link to coverage at MSNBC.

Google on "Sovereign immunity" patentYou might try learning some of the new WWW search technology. I went to Googleand it returned some excellent references, such as this first. One trick is using good keywords, and you must have missed my including "Sovereign immunity" in the OP.
As for international violations, they apply only where the patent has jurisdiction. The US government is free to violate french patents so long as they do so on American soil.

Re:It's time to start using of the "I" word
The "slippery slope" argument is inherently fallacious
It is?Remember, a slippery slope argument is only fallacious if the causality between the steps is unclear or non-existent.
Also remember, when free-speech activists decried the DMCA proposal because of its chilling effect, they were shouted down with "slippery slope fallacy!" as well. Yet one of the first to use the DMCA was the Church of Scientology to take down critics' sites.
Go get a logic class will you?

Re:Lies, Damn Lies and Statistics
Actally, if you had bothered to read TFA you'd have noticed that the information comes from a survey conducted by researchers at UCLA, which polls freshmen at universities across the country:
The survey
So who's part of the clueless masses now? -
Re:Lies, Damn Lies and Statistics
No. The study was done by the Higher Education Research Institute at UCLA, not solely of Freshmen at UCLA.
If you click the link provided on the CRN story page to the HERI web site and look at the FAQ for the study you will find a PDF document that lists all of the colleges and universities that participated last year (and every previous year back to 1966).
They aren't numbered. But I count 54 institutions on the first page and there are 26 pages in the document. That's 1400 colleges and universities. Granted, some of the institutions that participated in the past did not participate last year. But in any case it's a large study that encompasses many more than one university.
How about we raise the level of discourse here and try some cursory investigation before we post?
Did any of the moderators who modded up this post check to see if "Flexible Typhoon" was correct in his assertion that the study was only of UCLA freshmen? Is there some kind of mutually-reinforcing aesthetic of half-assed-ness here at slashdot? Do some fact-checking or you may reward a blow-hard.

I agree, but not everyone does
Whichever side you're on in the copyright debate, you have to agree this legislation is draconian and excessive, to say the least.
Obviously not, as Congress passed the bill.
Remember when you couldn't go to jail for copyright infringement unless you were profiting off the copyright infringement? Hard to believe the law has changed so much in only 8 years. Thanks a lot Bill Clinton, you opened up the floodgates.

requirements vary...I saw several posts that say a HS diploma or GED isn't strictly required by many colleges, and I'm thinking that's a load of BS. Of course they require diplomas.
Well, after looking at a few institutions, it appears a diploma isn't always a must-have after all:
- Harvard doesn't list it in the admission requirements.
- But, U Penn does require a completed secondary education program in their requirements.
- Some like Penn State are a little fuzzy - they require four years of secondary education, but not necessarily a diploma (?).
- UCLA again doens't state a diploma specifically, but does require very specific secondary education credits.
All in all, it looks like it's going to vary significantly from institution to institution. I suggest your friend find out where he/she wants to go to college and act accordingly. - Harvard doesn't list it in the admission requirements.

Re:Remember...
Nobody's talking about constant state monitoring of your vehicle's position. Where in the bill does it say that? Yes, I guess they could, in theory, track your vehicle's location, but they're not doing that.
And the income tax was originally 3%, and those who warned it might one day reach 10% were told they were paranoid. And your Social Security number was never to be used for identification purposes. The slippery slope is not always a fallacy. -
Re:Hmm
Slippery Slope arguments may not hold up in Logic class, but humans aren't logical. I saw this in another
/. post recently that really clears up why Slippery Slope arguments both are valid, and important to consider, when dealing with humans and politics.

Re:copyright in America
Copyright isn't criminal at all in the states. It's a purely civil offense, so the only redress is a suit.
I'm amazed anyone still believes this, given that it has not been true for eight years now: the No Electronic Theft act, signed into law by President Clinton in 1997, makes commercial piracy, or non-commercial piracy where the value of works pirated over a 180-day period exceeds $1000, a criminal offense, punishable by heavy fines, several years in jail, or both.
