An anonymous reader writes “NASA’s Mars rovers have been on the red planet for five years now. The rovers were originally planned to stay operational on the planet for only 90 days, but it has turned into a much longer mission than anticipated. NASA has put together a video to celebrate the anniversary. The rovers have made important discoveries about wet and violent environments on ancient Mars. They also have returned a quarter-million images, driven more than 21 kilometers (13 miles), climbed a mountain, descended into craters, struggled with sand traps and aging hardware, survived dust storms, and relayed more than 36 gigabytes of data via NASA’s Mars Odyssey orbiter. To date, the rovers remain operational for new campaigns the team has planned for them.”

An anonymous reader writes “ZDNet’s Adrian Kingsley-Hughes tested the latest Win7 build against XP and Vista and came to a surprising conclusion: Win7 performs better than the other 2 OSs in the vast majority of the 23 tasks tested. Even installation. ‘Rather than publish a series of benchmark results for the three operating systems (something which Microsoft frowns upon for beta builds, not to mention the fact that the final numbers only really matter for the release candidate and RTM builds), I’ve decided to put Windows 7, Vista and XP head-to-head in a series of real-world tests…’” This review shows only a 1-2-3 ranking for each test, so there’s no sense of the quantitative level of improvement.

ofcourseyouare writes “The Independent is a UK newspaper which has been pushing hard for cuts in CO2 emissions for years. It recently polled a group of ‘the world’s leading climate scientists,’ revealing a ‘growing support for geoengineering’ in addition to cutting CO2 — not as a substitute. For example, Jim Lovelock, author of The Gaia Theory, comments: ‘I disagree that geoengineering the climate is a dangerous distraction and I disagree that on no account should it ever be considered. I strongly agree that we now need a “plan B” where a geoengineering strategy is drawn up in parallel with other measures to curb CO2 emissions.’ Professor Kerry Emanuel of MIT said, ‘While a geoengineering solution is bound to be less than desirable, the probability of getting global agreement on emissions reductions before it is too late is very small.’”

UnknowingFool writes “As a followup to the Zune New Year’s Eve meltdown, Microsoft has issued a workaround for what some users have correctly guessed was a bug caused by a leap year. To recover from the problem, let the Zune drain the batteries and restart it after noon on January 1, 2009. Many sites are reporting that Microsoft has ‘fixed’ the issue, but technically all Microsoft has done is to ask users to wait out the conditions that triggered the bug. Unless a software patch comes out, Zunes will suffer the same problem again in four years.” Reader ndtechnologies adds, “According to posts in the Toshiba forum at anythingbutipod.com, the same bug that shut down millions of Zune 30’s also affects the Toshiba Gigabeat S. The Zune 30 is based off of the Gigabeat S series and was co-developed by Microsoft with Toshiba.”

AOL has been shutting down its free Web services, in some cases with little or no notice to users, and they are not the only ones. This blog post on the coming “datapocalypse” makes the case that those who host Web content should be required to provide notice and access to data for a year, and be held strictly accountable the way landlords are before they can evict a tenant. Some commenters on the post argue that you get what you pay for with free Web services, and that users should be backing up their data anyway. What do you think, should there be required notice and access before online hosts take user data offline for good?

Z80xxc! writes “FIRST (For Inspiration and Recognition of Science and Technology) has officially announced the 2009 FIRST Robotics Competition. This competition, started by inventor Dean Kamen, encourages high-school students to design and build robots to compete with and against other FRC teams. The competition overview video is available from NASA. This year’s competition is called ‘Lunacy.’ The game consists of a series of 135-second face-offs during which the student-designed robots must pick up 9-inch game balls and deposit them in trailers hitched to the opposing teams’ robots. The game field is coated with regolith, a slick polymer material, and special wheels are used to create a low-traction interaction with the crater’s surface. Together, these combine to simulate the one-sixth gravity on the surface of the moon. For any readers who are interested in participating, FRC teams can always use more adult mentors.”

Timothy R. Butler writes “Much to the chagrin of owners of various 2G cell phones on AT&T Mobility’s network, including the highly visible (and originally highly expensive) first-generation iPhone, we have discovered that AT&T has been quietly adjusting its network in ways that degrade 2G network performance as it has sought to build out its next-generation 3G network. Many of the phones affected, including BlackBerry devices, are still well within their two-year contract period.”

ancientribe writes “Security experts are cautiously on the lookout for some lesser-known but potentially lethal threats that could be more difficult to prepare for and defend against in 2009. These aren’t your typical enterprise hack attacks. They’re mainly large-scale Internet threats — attacks that knock out sections of the Internet infrastructure, radical extremist hackers, Web attacks that adversely affect online ad revenue, and even the unthinkable: human casualties as a result of a cyberattack.” Also known as the new group of things the fear mongers will use to make you do their bidding.

mattskent writes “I’m currently a junior in college working towards my Bachelor’s degree in Computer Science. As such, I’m starting to look pretty seriously at jobs in the IT/Computer Science field. I’ve spent plenty of time working entry-level IT jobs doing various kinds of help desk type work, and so most of the exposure I’ve had to the field is related to support of other people’s computers. I enjoy helping other people out, but I’d rather not be plugging things in and restarting computers the rest of my life. Although the possibility is growing on me, I don’t think I would particularly love to write code all day for a living either. What are some interesting jobs that you’ve had or heard of that I could look into fresh out of college with a Computer Science degree?”

fortapocalypse sends word that a new paper was published today in the journal Science on the hypothesis that a comet impact wiped out the Clovis people 12,900 years ago. (We discussed this hypothesis last year when it was put forth.) The new evidence is a layer of nanodiamonds at locations all across North America, at a depth corresponding to 12,900 years ago, none earlier or later. The researchers hypothesize that the comet that initiated the Younger Dryas, reversing the warming from the previous ice age, fragmented and exploded in a continent-wide conflagration that produced a layer of diamond from carbon on the surface. While disputing the current hypothesis, NASA’s David Morrison allows, “They may have discovered something absolutely marvelous and unexplained.”
