An anonymous reader writes "A story on Wired News reports the problems Jewish synagogues have protecting their Torahs from theft. The Torah scrolls, containing the five books of Moses, are hand lettered over the course of a year, are often hundreds of years old, and can sell for $50,000 or more. But Judaic law "dictates that not one character can be added to the 304,805 letters of the Torah's text", which makes them untraceable and easily sold on the black market. Rabbinic authorities have recently approved two computer-based systems to make the scrolls traceable: one takes a digital fingerprint of a Torah, a second makes microperforations in the parchment that yield a unique identifier."

karvind writes "BBC has an interesting story on the 50th birthday of atomic clocks. The first accurate caesium atomic clock was developed at the NPL in 1955 by Dr Louis Essen. And after 5 decades In September the US National Institute of Standards and Technology (NIST) used computer chip fabrication techniques to make a small atomic clock. The final development should see a battery-operated system about the size of a sugar lump. NIST also has a page on history of atomic clocks"

Rollie Hawk writes "The Tyrannosaurus rex has long been the darling of science fiction dinosaurs and has one of the most well-known skeletal designs among extinct creatures. But while even the most casual dinosaur enthusiast can identify the T. rex, until recently the sex of individual specimens was not discernable. Though dinosaurs are most known for their traits shared with modern reptiles, it is their kinship with birds that has finally revealed the sex of a T. rex fossil. To prepare for egg production, female birds develop a thick layer of medullary bone in their long bones, which acts as an extra source of eggshell calcium. According to Dr. Mary H. Schweitzer of North Carolina State University, the 'tyrant lizard king' appears to do the same thing. She explains that 'dinosaurs produced and shelled their eggs much more like modern birds than like modern crocodiles.'"

grqb writes "Reuters is reporting that strong growth for portable devices such as laptop computers, game and music players, PDAs and mobile phones is expected to pressure battery manufacturers to improve their products, which are quickly becoming the limiting step in portable technology development. The lithium-ion battery technology that is commonly used hasn't changed in several years. The race is on to find battery technologies that are lighter and have increased life, but major breakthroughs don't seem to be on the horizon other than the lithium polymer battery, which can squeeze roughly 10-20% more life than lithium-ion. Micro fuel cells that run off of methanol are touted to be the next major wave for portable power, although logistics and price still make these fuel cells long shots, which is why Nokia recently dropped development of this technology."

StudMuffin asks: "I teach graduate computer science courses at a Big 10 university to grad students, who have never programmed before and are studying Human-Computer Interaction or other Information Science specialties. These courses are usually their first dip into the programming pool, so we have tons to cover in three months. This fall, I have been asked to take over and redesign our 'Complex Website' course, which is getting a bit long in the tooth. This course has traditionally been about database backed websites with server-side scripting. My only requirements are that there be coverage of PHP and that we have basic instruction about persistence using a database (which must be MySQL). However, I believe that the nature of 'complex' websites has changed, with XHTML, CSS, Javascript, web services, and so on. Sites like Google Maps make the browser feel like a fat client and are making the web browser a true window onto enormous data sets, and take into consideration the MoRAS of small views on large worlds. What do Slashdot readers consider a reasonable curriculum would be for a redesigned course like this?"

YetAnotherName writes "The MPAA, which has worked hard to get a broadcast flag into US digital television, is unlikely to push for it, according to the EFF.

JJ Budion writes "If you've signed up for an account on Wikipedia.org, you may want to check this page to make sure you're not on there. It seems certain users with identical password hashes can find other user names with the same password, and Wikipedia (despite being alerted) has done nothing about the problem for the last year. A good (although slightly inflammatory) description of the problem can be found here. This is probably a good occasion to remember to use strong passwords (apparently only users with common passwords, like dictionary words, are affected)."

xbsd writes "John Stedman, a lieutenant in the Los Angeles County Sheriff's Department in charge of IP violations, testified in front of the Senate Homeland Security committee that some associates of terrorist groups such as Hezbollah may be involved in copyright violations. According to CNET's Declean McCullagh: 'Even though Stedman's evidence is circumstantial, his testimony comes as Congress is expected to consider new copyright legislation this year. An invocation of terrorism, the trump card of modern American politics, could ease the passage of the next major expansion of copyright powers'."

(Tor has been mentioned on Slashdot twice before.)"

Roland Piquepaille writes "Based on ideas taken from Wikipedia and dodgeball, Cellphedia allows its members to broadcast questions to its community and receive answers, using SMS text messaging on cell phones. Here is how it works, according to "Cellphedia Melds Facts with Mobile Smart Mobs" from E-Commerce Times. First, you register for free on the site and you indicate your subjects of interest. If you want to ask a question, it is sent to all the members who expressed interest in this particular subject. Finally, the first answer received by Cellphedia is sent back to you. This means that later answers, which could have been more accurate, are discarded. But this service is still very young and its creator is working hard to improve it. Read more for some examples of questions and answers stored on the Cellphedia central server."

peterdaly writes "As a proud new owner of a Mac mini, I quickly discovered the internal hard drive performance was so pathetic compared to what I was used to that I needed to do something about it ... preferably on the cheap. I ended up trying a FireWire attached storage enclosure and using an older 80GB drive I had in my closet from a dead PC. My mini got about a 75 percent disk performance increase for about $50 (or $100 if you need a drive). Here is a benchmark of before and after as well as information about my research and upgrade. If you already have at least 512MB RAM, this may be the best performance bang for your buck if you're looking for your mini to be faster and more responsive."

FleaPlus writes "ABC News, Pasadena Star-News, and Space Politics report on a recent statement by NASA chief Michael Griffin on NASA's plans for the future and how it will be reflected in their annual budget. Griffin has ordered preparations for one last shuttle servicing mission to the Hubble Space Telescope. He also plans to greatly accelerate development of the Crew Exploration Vehicle to have it ready when the Space Shuttles retire in 2010, stating that the CEV 'needs to be safe, it needs to be simple, it needs to be soon.' Some other highlights include $34 million for the Centennial Challenges prize program and the possibility of completing the space station with unmanned rockets after the shuttles retire. However, due to budget limitations, the cost of returning the Space Shuttles to flight, and over $400 million in Congressional earmarks, a number of other areas will see delays, including space station, aeronautics, and exploration research. NASA also plans on restructuring Project Prometheus to focus on developing space-qualified nuclear power systems for use in human and robotic surface operations, instead of a probe to Jupiter's moons." The Washington Post has a look at NASA's future as well.

FleaPlus writes "The Washington Times and Space.com has an article on a plan for a low-cost shuttle replacement by t/Space, an organization whose team includes AirLaunch LLC and Burt Rutan's Scaled Composites. Instead of a one-size-fits-all craft, t/Space's plan is to build an air-launched four-person capsule termed the Crew Transfer Vehicle (CXV), specialized for carrying people to and from low-Earth orbit. Once in orbit the CXV would dock with a separately-launched Crew Exploration Vehicle (likely built by Lockheed Martin or Northrop Grumman), which could be optimized for traveling between Earth orbit and the Moon. The CXV would also be able to dock with a space station or serve as a crew lifeboat. The group, which has already received some NASA funding, calculates that it can have the system ready by 2008 for $400 million, with a per-launch cost of $20 million (compared to ~$500 million per shuttle launch). Development would be done under a competitive fixed-price (instead of cost-plus) contract."

A: No. Chaos is hard to create, even on the Internet. Here's an example. Go to Amazon.com. Buy a book without using SSL. Watch the total lack of chaos.'"

brokencomputer writes "There is an interesting interview with Bram Cohen, the creator of BitTorrent, on my site, WrongPlanet.net. Because there is already a plethora of information about BitTorrent, this interview takes a different approach and focuses entirely on Cohen's Asperger's Syndrome. In addition to being interesting to anyone interested in BitTorrent, Cohen's story is extremely inspirational to those of us who do have Asperger's, and will probably be so even to those without Asperger's Syndrome."

nysus writes "Anti-evolutionists have made classrooms in Kansas a key battleground in America's culture war. Again. The New York Times reports they are proposing to change the definition of science in Kansas: 'instead of "seeking natural explanations for what we observe around us," the new standards would describe it as a "continuing investigation that uses observation, hypothesis testing, measurement, experimentation, logical argument and theory building to lead to more adequate explanations of natural phenomena."'" From the article: "In the first of three daylong hearings being referred to here as a direct descendant of the 1925 Scopes Monkey Trial in Tennessee, a parade of Ph.D.'s testified Thursday about the flaws they saw in mainstream science's explanation of the origins of life. It was one part biology lesson, one part political theater, and the biggest stage yet for the emerging movement known as intelligent design, which posits that life's complexity cannot be explained without a supernatural creator."

FleaPlus writes "The US Air Force has awarded a $100 million contract to SpaceX, an orbital rocket launch company which aims to 'increase the reliability and reduce the cost of access to space by a factor of ten.' The contract is for launch services on a recurring basis through 2010 on SpaceX's Falcon I rocket. The company has been mentioned previously on Slashdot. SpaceX was founded by former Paypal CEO Elon Musk, who was asked to testify before Congress last month on the future market for commercial spaceflight. Their Falcon I rocket recently completed structural qualification and initial test firings, and will be lifting off later this year at a per-launch price of $6 million. Their larger $16 million Falcon V rocket, designed to be able to carry people to orbit, are scheduled to launch next year."

Content based image retrieval (CBIR), the technique to search for images not by keywords, but by comparing features of the images themselves has been the focus of much research ever since the web emerged. Consider for instance adding CBIR to Google Images, where you would be able to search for images similar to a query image instead of using keywords. A research project at Penn State University has recently been applied to the biggest aviation photo database in the world with close to 800,000 images. You can search for images similar to a photo already in their database (click "View similar photos") or submit your own query image. Some queries generate better results than others but CBIR is certainly here to stay and will be standard in many image applications of the future.

Rollie Hawk writes "While many limits on stem cell research exist in the United States, scientist are finding wants to straddle or at least blur the line between man and animal. It's not quite The Island of Doctor Moreau, but it's bringing a pantheon of ethical dilemmas, nonetheless. The creation of chimeras, named for the mythical beast composed of parts from several different animals, has been in the news off and on for the last few months. The latest case involves around 50 sheep said to possess at least partially human organs. These heavily modded sheep are growning human-like organs such as livers, hearts, and blood. All of these could eventually be close enough to the real thing to be harvested as replacements parts. If that doesn't shock you, consider one other human organ that is being grown in some of these sheep: human brains. While it is doubtful that anyone would want a brain transplant from a human-sheep chimera, it does hold the possibility for doing brain research that would never be allowed on human beings. That is, unless, the brains end up being too human. Just the possibility of a human mind bouncing around inside a sheep's head is a scary proposition."

Spy Hunter writes "The Scalable Vector Graphics format has yet to take off on the web, perhaps due to a small installed base of SVG-enabled browsers. That could soon change as the latest Firefox 1.1 nightly builds have started coming with native SVG support compiled in and enabled by default. If this feature makes into the Firefox 1.1 release (which is not certain, but likely, as the developers want it to happen) it will increase the number of web users who have an SVG renderer installed. But perhaps more interesting than that is the possibility of mixing SVG graphic elements directly into the markup of regular XHTML pages, freeing vector graphics from the small rectangle of a browser plugin and opening up a host of exciting new possibilities for web developers. This is enabled by the integration of SVG directly into the Gecko rendering engine, instead of as a browser plugin. With such a useful web developer feature available only in Firefox, could we soon start seeing websites asking their users to download Firefox to get the best browsing experience?"

Slashback tonight with updates and clarifications on recent Slashdot stories (and story arcs), including a downright Operatic end to Jon S. von Tetzchner's cross-oceanic attempt (or was that just in fun?), the status of post-death email privacy, minimizing the dangers of RFID passports, and more - read on for the details.

Actually, it's taking tests that reduces IQ. The guys at Mind Hacks have dissected the widely reported story that 'email destroys the mind faster than marijuana' [Posted on Slashdot a few days ago -- T.] and found that it is more spin than science. The results show simply that people do worse at IQ tests when distracted, although Hewlett-Packard are not releasing details of the experiment, so others cannot even evaluate if the research is sound. The use of psychobabble for marketing marches on.

One day this will all be commemorated as ... an opera. GreyPoopon writes "It looks like Jon's attempt at swimming the Atlantic has ended in early failure. Taking the blame once again is is PR Manager, Eskil Sivertsen. The raft he was using was somehow punctured this morning, and Jon had to abondon his trek to perform a heroic rescue. Perhaps someone should take on the task of sending our downtrodden adventurer a cup of Mom's hot chocolate."

PCP theorem simplified, still way over my head. Stridar writes "Sanjeev Arora's proof of the PCP theorem was a great acheivement. This theorem, a reduction of NP to PCP, allowed for many striking results on the difficulty of finding approximate solutions to NP-Hard problems. However, his original proof is long and technical, focusing on the arithmetization of booelan formulas. It has long been an open problem to simplify this result. Now Irit Dinur , a mathematician at the Hebrew University, has given a purely combinatorial proof of the PCP theorem, in her exciting paper "The PCP Theorem by Gap Amplification" ."

I think several other things end at death, too. microbee writes "The Register reports that Yahoo has complied with a court order to give a dead soldier's email account to his parents. It's not clear to me from the news whether they got direct access to the actual mail box, or just hard copy of those emails. If the former, it's a bit funny to read "the family complain they have only got emails received by Justin, not those he wrote." People have to wonder whether their privacy ends at death."

Haven't they ever seen The Killing Fields? valdean writes "Following up on past Slashdot stories, Wired News reports that the State Department is now considering adding a password to the new RFID passports, in response to 'criticism from computer security professionals and civil libertarians.' According to the article, 'The data... would be locked and unavailable to any reader that doesn't know a secret key or password to unlock the data. To obtain the key, a passport officer would need to physically scan the machine-readable text that's printed on the passport page beneath the photo... The reader would then hash the data to create a unique key that could be used to authenticate the reader and unlock the data on the RFID chip.'"

gnuman99 writes "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.

Aglassis writes "It appears that NASA is not backing down from their nuclear space initiative. Project Prometheus has recently started a new web page (under JPL) and NASA is finishing up a period of public comment (last session today). Currently Northrop Grumman is contracted to begin preliminary design of the spacecraft until 2008 for NASA (the reactor will be built by the Department of Energy's Division of Naval Reactors--the folks who control all US submarine and aircraft carrier nuclear reactors). Early specs are that it will be 60 meters long, have a 30,000 kg mass, use a 100 KW reactor using Brayton cycle gas turbines, be powered by ion thrusters with a 7000 second specific impulse, and have a science payload of 1500 kg. Early mission plans for Prometheus 1 (Jupiter Icy Moons Orbiter) indicate that the spacecraft would orbit Callisto, Ganymede, and Europa individually, and perhaps have a lifespan of about 20 years."

FleaPlus writes "The MIT Technology Review has an article predicting where the mainstream of the environmental movement may likely reverse its collective stance in the next ten years. The four areas discussed are population growth, urbanization, genetically-engineered organisms, and nuclear power. The article is written by Stewart Brand, known for creating the Whole Earth Catalog, the WELL online community, and the Long Now Foundation. Brand also has some interesting comments regarding the sometimes-conflicting interaction between romantics and scientists in the environmental movement. There's an online debate between Brand and former DOE official Joseph Romm on TR Blogs." Frankly, unless humanity decides to undergo a massive collective personality change of not being consumption-focused, I don't see much other way around these particular issues. What we all need is an Arthur to keep us depressed and sleeping in darkened rooms to lower energy consumption.

deglr6328 writes "In what is being heralded variously as a "remarkable accomplishment" and a "breakthrough", physicists have reportedly beaten the diffraction limit at optical frequencies. First hypothesized to be possible 30 years ago by Russian physicist Victor Veselago, meta-material "superlenses" with negative refractive indices were first demonstrated around 2001 at microwave frequencies. The use of a thin silver film as an optical superlens in this case, has allowed the team to resolve features less than 40 nanometers wide; 10 times better than any conventional optical microscope. The consequences of the discovery are immediately apparent and include opportunities for extremely fine biomedical imaging in-vivo and greater increases in transistor density for microchips by superlens augmentation of photolithography masks."

Sanity writes "Michel Rocard, economist and former French prime minister, has just published a report on the European Software Patents Directive. He is the European Parliament's draftsperson or "rapporteur" on the directive, and so it is likely that his views will be taken very seriously.
