It's true to say that a major factor in the premature curtailment of the orginally planned series of Apollo missions was the entirely rational fear that the more missions launched, the greater the probability of a total loss of missions and crew, and that this would lead to a complete loss of public support for NASA.

Submission + - KDE 4 uses 40% less memory despite 3D eye-candy

Submitted by
An anonymous reader writes: Pro-Linux reports that KDE 4, scheduled to be released in January 2008, consumes almost 40% less memory than KDE 3.5, despite the fact that version 4 of the Free and Open Source desktop system includes a composited window manager and a revamped menu and applet interface. KDE developer Will Stephenson showcased KDE 4's 3D eye-candy on a 256Mb laptop with 1Ghz CPU and run-of-the-mill integrated graphics, pointing out that mini-optimizations haven't even yet been started. Will this combination of resource efficiency and consumer appeal make KDE 4 the leader in the booming Linux-based ultra mobile laptop and energy efficient desktop markets?

Submission + - Huge offshore wind power programme launched in UK

Submitted by OriginalArlen
OriginalArlen writes: The UK government has announced an ambitious plan to expand the existing, already extensive offshore wind turbine farms to an estimated 7000 units, enough to generate 20% of the UK's power needs by 2020. The newly green-friendly Conservative opposition party is also backing the scheme. Wonder what they'll make of it in Oregon...

Submission + - Electric Cars to Help Utilities Load Balance Grid

Submitted by
Reservoir Hill
Reservoir Hill writes: "A team at the University of Delaware has created a system that enables vehicles to not only run on electricity alone, but also to generate revenue by storing and providing electricity for utilities. The technology, known as V2G, for vehicle-to-grid, lets electricity flow from the car's battery to power lines and back. When the car is in the V2G setting, the battery's charge goes up or down depending on the needs of the grid operator, which sometimes must store surplus power and other times requires extra power to respond to surges in usage. The ability of the V2G car's battery to act like a sponge provides a solution for utilities, which pay millions to generating stations that help balance the grid. Willett Kempton, who began developing the technology more than a decade ago, estimates the value for utilities could be up to $4,000 a year for the service, part of which could be paid to drivers. A car sitting there with a tank of gasoline in it, that's useless," says Kempton. "If it's a battery storing a lot of electricity and a big plug that allows moving power back and forth quickly, then it's valuable.""

Submission + - First details of manned Mars mission from NASA (bbc.co.uk)

Submitted by OriginalArlen
OriginalArlen writes: The BBC has a first look at NASA's initial concepts for a manned Mars mission, currently pencilled in for 2031. The main vehicle would be assembled on orbit over three or four launches of the planned Ares V heavy lift rocket. New abilities to repair, replace, and even produce replacement parts will be needed to provide enough self-sufficiency a 30 months mission, including 16 months on the surface. The presentation was apparently delivered at a meeting of the Lunar Exploration Management Group, although there's nothing on their site yet.

Submission + - Coppola loses all his data 4

Submitted by Colin Smith
Colin Smith writes: This is really an object lesson in backup methodology.

Film director Francis Ford Coppola has appealed for the return of his computer backup device following a robbery at his house in Argentina on Wednesday. He told Argentine broadcaster Todo Noticias he had lost 15 years' worth of data, including writing and photographs of his family.

Submission + - Do Not Call listings to expire in 2008. (yahoo.com)

Submitted by
Ant
Ant writes: "Yahoo! News report that the cherished dinner hour void of telemarketers could vanish next year for millions of people when phone numbers begin dropping off the national/United States (U.S.)'s Do Not Call list. The Federal Trade Commission (FTC), which oversees the list, says there is a simple fix. But some lawmakers think it is a hassle to expect people to re-register their phone numbers every five years. Numbers placed on the registry, begun in June 2003, are valid for five years. For the millions of people who signed onto the list in its early days, their numbers will automatically drop off beginning next June if they do not enroll again... Seen on Blue's News."

Microsoft No Longer a 'Laughingstock' of Security? 282

Posted by Zonk from the set-the-bar-high-guys dept.
Toreo asesino writes "In a Q&A with Scott Charney, the vice president of Trustworthy Computing at Microsoft, Charney suggests that security in Microsoft products has moved on from being the 'laughing stock' of the IT industry to something more respectable. He largely attributes this to the new Security Development Lifecycle implemented in development practices nearly six years ago. 'The challenge is really quite often in dealing with unrealistic expectations. We still have vulnerabilities in our code, and we'll never reduce them to zero. So sometimes we will have a vulnerability and people say to me, "So the [Security Development Lifecycle (SDL)] is a failure right?" No it isn't. It was our aspirational goal that the SDL will get rid of every bug.'"

Sun Says OpenSolaris Will Challenge Linux 405

Posted by kdawson from the color-us-skeptical dept.
E5Rebel writes "Sun Microsystems has ambitious plans for the commercial and open source versions of its Solaris operating system. The company hopes to achieve for Solaris the kind of widespread uptake already enjoyed by Java. This means challenging Linux. 'There's an enormous momentum building behind Solaris,' according to Ian Murdock, chief operating platforms officer at Sun, who was chief technology officer of the Linux Foundation and creator of the Debian Linux distribution. Isn't it all a bit late?"

Submission + - Government won't allow green car sales (msn.com)

Submitted by
Geoffrey.landis
Geoffrey.landis writes: "Auto industry blogger Lawrence Ulrich notes that Honda is now making a "Partial Zero Emissions Vehicle" (or PZEV for short) version of the 2008 Accord, an all-new vehicle that is redesigned to meet California emission standards. He notes "So, just how green is a PZEV machine? Well, if you just cut your lawn with a gas mower, congratulations, you just put out more pollution in one hour than these cars do in 2,000 miles of driving." But the irony is that it's actually illegal for automakers to sell these green cars outside of the special states they were designed for! Apparently, anybody selling one of these ultra-green vehicles out of the correctly-designated venue — which means either California, or seven northeast-states with similar pollution laws — "could be subject to civil fines of up to $27,500. Volvo sent its dealers a memo alerting them to this fact, noting that its greenest S40 and V50 models were only for the special states.""

Submission + - Scientist must pay to read his own CC'd paper (cam.ac.uk)

Glyn Moody
Glyn Moody writes: "Peter Murray Rust, a chemist at Cambridge University, was lost for words when he found Oxford University Press's website demanded $48 from him to access his own scientific paper, in which he holds copyright and which he released under a Creative Commons licence. As he writes, the journal in question was "selling my intellectual property, without my permission, against the terms of the licence (no commercial use)." In the light of this kind of copyright abuse and of the PRISM Coalition, a new FUD group set up by scientific publishers to discredit open access, isn't it time to say enough is enough, and demand free access to the research we pay for through our taxes?"

Submission + - Facebook Leaves Advertisers Exposed to Hate Speech (newscloud.com) 1

NewsCloud writes: "Does Facebook believe that no publicity is bad publicity? Why else would they leave a group called, "Fuck Islam" open since July 21, 2007 despite more than 53,482 members joining an opposing group called petiton: if "f**k Islam" is not shut down..we r quitting facebook group. Furthermore, advertisers such as Sprint, Verizon, T Mobile, Target, Qwest and French's wouldn't be too happy to learn that they are paying for ads on the "Fuck Islam" group pages.

I'm not advocating a policy against free speech, just strict enforcement of Facebook's own Terms of Use. The group name is clearly vulgar and obscene. Arguably, inflammatory and hateful. Facebook has positioned itself as the darling of the social network world, without the spam, porn and the sex offender problems of MySpace. Yet, this sort of thing isn't new to Facebook (see Facing Up to Facebook Racism and Elder hate groups on facebook. There's even an active group called I hate Iraqis targeting Iraqi refugees fleeing to Jordan.
Shouldn't a startup like Facebook, worth reportedly more than a billion dollars with over a hundred employees be expected to comply with its Terms of Use in less than six weeks?"

Submission + - Six minutes of terror: landing humans on Mars

Submitted by OriginalArlen
OriginalArlen writes: Universe Today has a fascinating article discussing the difficulty of executing EDL (entry, descent, landing) on Mars for vehicles bigger than MER, Viking and Pathfinder, and for manned craft in particular. Airbags can't be used for obvious reasons, but the atmosphere is too thin to be used for parachutes or aerobraking by large heavy vehicles, and the stronger gravity (compared to the moon) makes an Apollo-style powered descent impossible. The best current idea is a huge inflatable torus called a hypercone.

Submission + - The impossibility of colonising the galaxy (antipope.org)

Submitted by OriginalArlen
OriginalArlen writes: The science fiction writer Charlie Stross has written an excellent and comprehensive explanation of why, a million SF books, movies and games not withstanding, human colonisation of other star systems is impossible. This may seem a controversial idea, although it seems commonsensical to many — fortunately, Charlie makes a clear-headed and unarguable case, so far as I can see.

Nevertheless it would be interesting to see reasoned responses from the community who believe this is not merely possible, but inevitable — and even, as Hawking has said, vital for the survival of the species. So, who's right — Hawking or Stross?
