dtjohnson writes "The National Snow and Ice Data
Center (NSIDC) has been at the forefront of predicting doom in the arctic as ice melts due to global warming. In May, 2008 they went so far as to predict that the North Pole would be ice-free during
the 2008 'melt season,' leading to a lively Slashdot discussion. Today, however, they say that they have been the victims of 'sensor drift' that led
to an underestimation of Arctic ice extent by as much as 500,000 square
kilometers. The problem was discovered after they received
emails from puzzled readers, asking why obviously sea-ice-covered
regions were showing up as ice-free, open ocean. It turns
out that the NSIDC relies on an older, less-reliable method of tracking
sea ice extent called SSM/I that does not agree with a newer method called AMSR-E. So why doesn't NSIDC use the newer AMSR-E data? 'We do not use AMSR-E data in our analysis because it
is not consistent with our historical data.' Turns out that the AMSR-E data only goes back to 2002, which is probably not long enough for the NSIDC to make sweeping conclusions about melting. The AMSR-E data is updated daily and is available to the public. Thus far, sea ice
extent in 2009 is tracking ahead of 2005, 2006, 2007, and 2008, so
the predictions of an ice-free north pole might be premature."

The series of bulletin boards called 'newsgroups' shared by thousands of computers, which traded new messages several times a day, is now a thing of the past."
An anonymous reader writes "Raytheon is bringing 'Iron Man' to life, according to EETimes. 'The movie opens in theaters worldwide today, but the real "iron man" has already been under construction at Raytheon Company (Salt Lake City, Utah) since 2000. Raytheon's Exoskeleton project is the brainchild of project leader Stephen Jacobsen and is being funded by the U.S. Army. The project, according to the company, permits soldiers to don an Exoskeleton suit that amplifies their strength — enabling them to lift 200-pound payloads without tiring.'"

Darkman, Walkin Dude writes "An internet group calling itself Anonymous has declared war on the Church of Scientology, in the form of an ominous posting to the YouTube site. 'In the statement, the group explained their goal as safeguarding the right to freedom of speech. "A spokesperson said that the group's goals include bringing an end to the financial exploitation of Church members and protecting the right to free speech, a right which they claim was consistently violated by the Church of Scientology in pursuit of its opponents." The press release also claimed that the Church of Scientology misused copyright and trademark law in order to remove criticism from websites including Digg and YouTube. The statement goes on to assert that the attacks from the group "will continue until the Church of Scientology reacts, at which point they will change strategy".' It should be noted that Slashdot users have had interactions with Scientology in the past as well."

ZDOne writes "ZDNet UK is reporting that it will not be known until the Android software development kit comes out on Monday whether the Gphone will be strictly Java-based, but security experts claim that the less smart a phone is, the less vulnerable it is. Android developers should stick to a semi-smartphone platform because the Java sandbox can protect against the normal kinds of attacks, experts claim. The article also discusses some of the pros and cons of open vs. closed source security. 'The debate about the relative security merits of open-source as opposed to proprietary software development has been a very long-running one. Open-source software development has the advantage of many pairs of eyes scrutinizing the code, meaning irregularities can be spotted and ironed out, while updates to plug vulnerabilities can be written and pushed out very quickly. However, one of the disadvantages of open-source development is that anyone can scrutinize the source code to find vulnerabilities and write exploits. The source code in proprietary software, on the other hand, can't be directly viewed, meaning vulnerabilities need to be found through reverse engineering.'"
