Vict0r writes "Researchers at the Georgia Tech Research Institute have recently demonstrated a way to grow carbon nanotubes in towers. The article also discusses applications for solar cells." From the article: "Reflections off the Gothamesque towers would provide more opportunity for each photon of sunlight to interact with the p/n junction of the cell. That would increase the power output from PV cells of a given size, or allow cells to be made smaller while producing the same amount of power."

Foobaz writes "Until now, the only application that can play audio on Apple's AirPort Express has been Apple's own iTunes. But Rogue Amoeba, makers of Audio Hijack, just released Airfoil, a program that lets you redirect anything to your AirPort Express, like streaming audio from mplayer, RealPlayer, or VLC."

Viridian writes "Jef Raskin, GUI pioneer, interface expert, Apple employee #31, and the man most credited with the creation of the Apple Macintosh, died of cancer on Saturday February 26, 2005. It was Raskin who named it after his favorite fruit, the McIntosh apple, although he said that he changed the spelling to "Macintosh" to avoid potential copyright conflicts with McIntosh, the audio equipment manufacturer."

fenimor writes "The kilogram is the only one of the seven basic units of the international measurement system defined by a physical artifact rather than a natural phenomenon. International team of scientists suggest replacing the kilogram artifact -- a cylinder of platinum-iridium alloy about the size of a plum --with a definition based on one of two unchanging natural phenomena, either a quantity of light or the mass of a fixed number of atoms. They propose to adopt either one of two definitions for the kilogram by selecting a specific value for either the Planck constant or the Avogadro number."

An Anonymous Reader writes "In a recent presentation and post, Kent Beck (eXtreme Programming, Embrace Change) highlights Open Quality Dashboards as a means to make software development accountable. Many different approaches attempt to reduce the number of issues creeping in all along the development process. Whether a shop abides by the rules of up-front UML design or test-driven development, or a methodology somewhere in between, the ongoing burst of popularity for tools enabling continuous integration and frequent releases shows the need for unit testing to appear earlier in the development process. In this context, quality dashboards could well establish a credible benchmark for software accountability."

ChrisMDP writes "Tom's Hardware has an interesting interview with Mitch Kapor, the chairman of the Mozilla Foundation. They discuss, amongst other things, what it's like competing with Microsoft, and Firefox as an operating system." From the interview: "Pragmatically, I think we have to distinguish between a base set of extensions and everything else. It gets progressively more difficult to create seamless solutions when there are nearly infinite possibilities for customization and tweaking of settings. There's a basic tension in principle that can never be completely resolved."

Wohngebaeudeversicherung writes "Astronomers have discovered a galaxy about 50 million lightyears away from earth that appears to be composed entirly of dark matter. This galaxy, dubbed VIRGOHI21 is rotating like a real galaxy, at speeds only explainable through massive amounts of matter, thought no single visible star could be detected."

Brian writes "In the wake of news that Microsoft is developing prototype software to detect rootkits, SysInternals has released a free rootkit detection tool named RootkitRevealer for all Windows systems NT4+. RootkitRevealer works by "comparing the results of a system scan at the highest level with that at the lowest level," and detects every known rootkit at rootkit.com. They also report that it is impossible to know for sure that a given system is clean from within it, but that defeating their tool would require a level of sophistication not yet seen. You can download RootkitRevealer."

Baricom writes "Just a few weeks after a major power outage took out well-known blogging service LiveJournal for several hours, almost all of Wikimedia Foundation's services are offline due to a tripped circuit breaker at a different colo. Among other services, Wikimedia runs the well-known Wikipedia open encyclopedia. Coincidentally, the foundation is in the middle of a fundraising drive to pay for new servers. They have established an off-site backup of the fundraising page here until power returns."

MondoMor writes "Apparently, the atmosphere above Earth's strongest storms acts like a particle accelerator, according to a UC Santa Cruz paper. TGFs (Terrestrial Gamma ray Flashes) may occur as seldom as 50 times a day, 'but the rate could be up to 100 times higher if, as some models indicate, TGFs are emitted as narrowly focused beams that would only be detected when the satellite is directly in their path.' I'm glad the gamma-ray bursts are directed into space."

fenimor writes "Much like the popular SETI@Home distributed computing project that searches radio telescope data for signs of extraterrestrial life, the new Einstein@Home will search for gravitational waves in data collected by U.S. and European gravitational wave detectors. Albert Einstein's General Theory of Relativity predicted the existence of gravitational waves in 1916, but only now has technology reached the point that scientists hope to detect them directly."

A key question is whether the US economy will benefit relative the rest of the world, with some arguing that new technologies such as clean power generation and energy efficient appliances will provide an economic boost."

rickbassham asks: "With VoIP really catching on these days, I decided to look into it for keeping deployed soldiers in touch with family and friends. I am currently a soldier in Iraq, and have the ability to get satellite-based internet, thanks to a few of the locals. While individually it is prohibitively expensive, a group of soldiers can come together to purchase a decent-to-high-speed internet connection. One of my plans is to link other soldiers to Vonage or another VoIP provider, so they will be able to keep in touch. Understanding the latency issues with VoIP via satellite (not to mention the other disadvantages), what upload speed does Slashdot recommend as a minimum for a QoS enabled connection for about 15-20 soldiers? The same for a non-QoS connection? What recommendations do you have for a good VoIP provider?"

Photographers taking pictures of the sculpture have been charged money by the city. The park district is claiming that pictures of the park violate the designers' and artists' copyrights. Quoth Karen Ryan, the press director for the park's project, "The copyrights for the enhancements in Millennium Park are owned by the artist who created them. As such, anyone reproducing the works, especially for commercial purposes, needs the permission of that artist." In response, Chicagoland bloggers have been posting as many pictures as they can get of The Bean."

Their proposal is to build a new Hubble Origins Probe, reusing the Hubble design but using lighter and more cost-effective technologies. The probe would include instruments currently waiting to be installed on Hubble, as well as a Japanese-built imager which 'will allow scientists to map the heavens more than 20 times faster than even a refurbished Hubble Space Telescope could.' It would take an estimated 65 months and under $1 billion to build, less than the estimated cost of a service mission."

ThinkMagnet (James Mitchell) writes " Blink: The Power of Thinking Without Thinking is Malcolm Gladwell's foray into the study of intuitive decision-making. The author, a former Washington Post science and technology writer, reveals his journalistic background in his narrative style. His assertions are based on recent scientific findings, but are always presented as a story. This makes good conversation fodder, but can frustrate readers who prefer direct presentation of scientific arguments." Read on for the rest of Mitchell's review. Blink: The Power of Thinking Without Thinking author Malcolm Gladwell pages 288 pages publisher Little, Brown (January 11, 2005) rating 8 reviewer James Mitchell ISBN 0316172324 summary This book discusses in narrative style the mechanics of subconscious snap decisions.

First, Gladwell introduces a concept called "thin-slicing." This involves the human brain's critical reduction of information to make predictions about complicated systems. For example, a system developed at the University of Washington can predict with 95% accuracy whether a couple will be divorced within fifteen years, based entirely upon one hour of observed interaction.

Next, Gladwell discusses analogous ways the human brain uses thin-slicing to make subconscious snap decisions. Interestingly, this rapid decision-making process can easily be primed by external influences. External influences affect more decisions than many people care to admit; these factors form the basis for snap judgments and first impressions.

Gladwell relates a study of how well a subject's personality was evaluated either by strangers who visited the subject's dorm room for fifteen minutes or by friends that knew the subject well. Friends were more accurate about extraversion and agreeableness, but the strangers were better at gauging conscientiousness, emotional stability, and openness to new experiences. Thin-slicing isn't always correct; it depends on having the right information.

Superficial traits can be used to the advantage of an actor trying to project a particular characterization. Similarly, an authority figure can dress and behave in a particular fashion to influence subordinates. Warren G. Harding made overwhelmingly positive first impressions throughout his political career, although he is considered by historians to be one of the worst American presidents. Despite his consistently lackluster performance, his attractive bearing and appearance camouflaged his shortcomings.

On the other hand, by understanding the fallibilities of intuition, one can influence others' unconscious decision-making processes and be more aware of influences on one's own intuition. People can control and develop their intuitive decision-making skills. For instance, a successful car salesman would never be distracted by the appearance of a customer to the detriment of a sale. A portion of the book discusses physiological tests that reveal the strength of stereotypes in subconscious decision making by measuring reaction times.

Having defined the capabilities and limitations of intuitive decision-making, Gladwell spends a chapter focusing on spontaneity through the story of General Paul Van Riper and Millennium Challenge '02. A technologically advanced military with a vast array of information collection and "common operational picture" was pitted against a less technologically capable adversary led by General Van Riper. Much as David defeated Goliath, Van Riper's force inflicted staggering losses on his information-gorged enemy. His victory illustrates the utility of pre-arranged structure (such as "commander's intent" or "desired endstate") to empower subordinates to make spontaneous decisions. The fog of war couldn't really be defied, but decision makers could be trained to cope well with uncertainty.

The latter parts of the book discuss how intuitive decision-making can fall short. Humans' senses and subconscious minds can be negatively affected in stressful environments where stimuli are distorted and thin-slicing can easily go awry. Gladwell takes examples from recent developments in police procedures designed to avoid situations that adversely affect law enforcement personnel. For instance, many departments make their officers patrol individually. Without partners, they are more likely to wait for backup before entering dangerous situations. The author also performs a detailed deconstruction of the Amadou Diallo shooting in New York City. He concludes that the tragedy was not a product of conscious injustice, but simply a chain reaction of impaired snap decisions made within seven seconds of violence.

Overall, Blink makes for a quick read and is sure to stimulate conversation. Its premise is simple, and it contains ample food for thought. Its discussion of priming the intuition with particular stimuli and impaired "thin-slicing" provides a useful tool in deconstructing human behavior. The strengths and weaknesses of intuition-priming and thin-slicing are useful knowledge for any professional decision-maker.

RichiH writes "Most of you have probably heard that science journals are getting more and more expensive. In hard numbers, 215% increase in price over the last fifteen years. What proves a major problem for libraries and interested individuals is great for the publishers. Reed Elsevier, with about 1700 scientific magazines the leading publisher, had a profit margin of 33.8% in 2003. With most research which is published, the taxpayers get the bill while the publishers get the money. So now for the good news: People are starting to fight this. Creative Commons is a good way, for example. Additionally, there are several magazines available which are based on a author-pays basis. If this sounds like a strange idea, think again. If Cell prints an article by you, you are charged $1000 for the first and $250 for each additional graphic you include. And this is for a reader-pays magazine! With PLoS Biology, the author pays $1500 for the whole article and the reader gets the magazine for free on the internet. Biomed Central lists 100 free magazines while the Directory of Open Access Journals lists an amazing 1425. I for one considered getting the $160 a year print subscription of PLoS just Because."

Several states and research institutions have been using their own money to undertake research. The AP coverage is up as well. Update: 01/24 19:40 GMT by J : Carl Zimmer has a fascinating description of the sugars we humans lack that contaminated the stem cell lines. What a curious genetic heritage we have...

News for nerds writes "Following the news of Sony slashing its profit forecast due to the underperforming AV & PC divisions, Ken Kutaragi, president of Sony Computer Entertainment Inc. (SCEI) known by the PlayStation brand, admitted he and other Sony employees have been frustrated for years with management's reluctance to introduce products like Apple Computer Inc.'s iPod, mainly because Sony had music and movie units that were worried about content rights. The PSP by SCEI is one of the first Sony products that support non-proprietary standards such as MP3 or H.264, and now SCEI considers opening up the UMD disc format employed in the PSP."

conJunk points out this AP story carried by Salon (also covered by various sources linked from Google News) "about the Pentagon's plan to send robot soldiers to Iraq in March or April. The program, Special Weapons Observation Reconnaissance Detection Systems, uses Foster-Miller TALON robots, and is said to be "years ahead of the larger Future Combat System vehicles currently under development by big defense contractors such as Lockheed Martin and General Dynamics Corp." If it's successful, maybe our men and women in uniform will have to team up with the United Auto Workers to fight the robo-threat to their jobs." Note that (whatever other considerations you might have about such deployment), the Rules of Robotics that some readers have linked to don't really apply to remote-controlled drones, which is what these are.

fthiess writes "Comment spam is in many ways even more annoying than regular email spam, since you generally have to do more than just hit the delete button to get rid of it. Its defining characteristic is that spammers abuse websites where the public can add content (blogs, wikis, forums, and even top referrer lists) to increase their own ranking in search engines. It seems, however, that the days of content spam are numbered: today Google announced that, in partnership with MSN Search and Yahoo!, that they have implemented a way to block content spam." (More below.)

"Briefly, you just change your blogging/wiki/forum/etc. software so that any hyperlinks in publicly-contributed text have a new rel=nofollow attribute added to any anchor tags. Google, MSN, and Yahoo! will now no longer index any such links, so the motive for content spamming disappears. Especially hopeful is the fact that a slew of makers of blogging software, including Six Apart, have announced they are supporting the new attribute."

My criteria is that the card support (or be capable of in future firmware) Encrypted QAM, and that the card ignore the broadcast flag. I'll need to make my choice before July 1st, 2005. Of the few cards available that support HDTV, 64/256-QAM support (needed for cable broadcast) is spotty and it's not clear which cards currently ignore the broadcast flag.

eric3xxx asks: "A week or so after Christmas, I tried to connect to my home wireless network and while I could see my access point I could not connect. After scanning the network, it turned out that there were at least twenty new access points in my apartment building (and in the surrounding buildings). Most of them had names such as 'linksys' and were all set on their respective vendors default channel (apparently a lot of people received 802.11b/g WAPs as presents). I tried changing the channel on my access point, starting at 1 and continuing through all of the channels, and none of them worked (probably since the channels overlap). In any case, I have no clear solution to this problem. I suppose I could boost the signal, however, that also increases noise. Perhaps I could convince my neighbors to put together a shared wireless network. I may just switch to 802.11a since it isn't as widely used." Has anyone else had success in configuring their APs to work in an areas of heavy wireless traffic?

Gebraucht von Neuwagen writes "This finding adds extremely salty water to the extreme environments where extremophiles can live. The Discovery Basin contains a brine that has the highest concentration of magnesium chloride found thus far in a marine environment; such concentrations are considered anathema to life. The researcher was quoted saying: "This in turn adds to arguments that life could exist outside the Earth""

kinema writes "A few days ago the Supreme Court of Connecticut ruled that the town of Greenwich's Department of Information Technology does not have to release the images and GIS data that the town keeps. The court found that mandatory disclosure of the data under the state's freedom of information statues is exempted under a recently passed state law that allows information to be kept secret 'when there are reasonable grounds to believe that their disclosure may result in a safety risk.' I'm sure I'm not the only one in the audience that has a hard time swallowing this. I am looking into filing a similar request to obtain the GIS data for the Portland Oregon metro area. As the data is currently available to anyone willing to shell out the nearly $900 per year, the local government isn't going to be able to argue that the data could be used by terrorists and should therefore be kept from the public which paid untold amounts for the data to be collected through their taxes." Update: 01/11 16:51 GMT by M : This story is incorrect. Although the case was just heard by the court, there has been no decision either for or against the disclosure of the GIS information.

brlcad writes "After 20 years of active development under a proprietary government license agreement, the BRL-CAD solid modeling suite has just been released as Open Source software. BRL-CAD is one of the many legacies of the late Michael Muuss, author of ping. The package began on the PDP-11 and VAX 11/780--before the emergence of ANSI/ISO C language standards--and boasts one of the first parallel Ray tracers in existence. Today BRL-CAD has over 750,000 lines of source code. It incorporates both 3D modeling and rendering capabilities, and supports an API for user-developed geometric analysis applications. It continues to be developed and maintained by the U.S. Army Research Laboratory and its partners. Various portions of the package are distributed under the GPL, LGPL, GFDL, and BSD licenses."
