Comment Re:Hmmm... (Score 1) 727

>Logarithm tells us that 2+2 != 4, but rather 3.99 [ad infinitum] - how's that for a bit of confusion.

But,

3.999... = 3 + 0.999... = 3 + 0.333... + 0.333... + 0.333... = 3 + 1/3 + 1/3 + 1/3 = 3 + 3/3 = 3 + 1 = 4.

So logarithms are right. There are more than four ways to write two squared.

The ISS Marks 10 Years In Space 153

Matt_dk writes to point out the upcoming tenth anniversary of the International Space Station in two days' time. "On 20 November 1998, a Russian Proton rocket lifted off from the Baikonur Cosmodrome for a historic mission: It was carrying the first module of the International Space Station ISS, named Zarya (Russian for 'dawn'). This cargo and control module, which weighs about 20 tonnes and is almost 13 meters long, provides electrical power, propulsion, flight path guidance and storage space. The launch of the module... heralded a new era in space exploration, as, for the first time ever, lasting cooperation in space was achieved between Russia, the US, Europe, Canada and Japan. Over the next ten years, many other modules were brought into orbit, and ISS developed into the largest human outpost in space. Since that time, the building blocks, transported by Russian launch vehicles or the US Space Shuttle, have expanded the ISS to the size of a soccer pitch and a current total mass of about 300 tons."

Why the Widening Gender Gap In Computer Science? 1563

ruheling writes "From yesterday's New York Times: ' What Has Driven Women Out of Computer Science?' In many US universities, over the past decade, there has been deliberate effort to integrate and encourage women and girls to get more involved in the 'hard' sciences, engineering, and math. However, instead of the proportion of women to men increasing, in Computer Science the opposite is actually true. Specifically, in 2001-2, only 28 percent of all undergraduate degrees in computer science went to women. Now many computer science departments report that women now make up less than 10 percent of the newest undergraduates. What's going on here, folks?"

Discuss the US Presidential Election & Education 1515

In 24 hours, many of you will be able to vote. So as we come down to the wire, this is really our last chance to talk about the issues. We've already discussed Health Care, the War, and the Economy. Today I'm opening up the floor to discuss education. Perhaps no other issue will matter more in 50 years. Which candidate will make the next generation smarter?

Why RAID 5 Stops Working In 2009 803

Lally Singh recommends a ZDNet piece predicting the imminent demise of RAID 5, noting that increasing storage and non-decreasing probability of disk failure will collide in a year or so. This reader adds, "Apparently, RAID 6 isn't far behind. I'll keep the ZFS plug short. Go ZFS. There, that was it." "Disk drive capacities double every 18-24 months. We have 1 TB drives now, and in 2009 we'll have 2 TB drives. With a 7-drive RAID 5 disk failure, you'll have 6 remaining 2 TB drives. As the RAID controller is busily reading through those 6 disks to reconstruct the data from the failed drive, it is almost certain it will see an [unrecoverable read error]. So the read fails ... The message 'we can't read this RAID volume' travels up the chain of command until an error message is presented on the screen. 12 TB of your carefully protected — you thought! — data is gone. Oh, you didn't back it up to tape? Bummer!"

Paralyzed Man Walks Again Using Exoskeleton 192

dominique_cimafranca notes a story up at the Daily Mail in the UK about a partially paralyzed man who is able to walk again using an exoskeleton frame. The article goes a bit far in comparing the device to Robocop, but it does show pictures of the man, paralyzed for the last 20 years, regaining some use of his legs. Quoting: "The device, called ReWalk, is the brainchild of engineer Amit Goffer, founder of Argo Medical Technologies, a small Israeli high-tech company. Something of a mix between the exoskeleton of a crustacean and the suit worn by Robocop, ReWalk helps paraplegics — people paralyzed below the waist — to stand, walk and climb stairs. The system, which requires crutches to help with balance, consists of motorized leg supports, body sensors and a back pack containing a computerized control box and rechargeable batteries."

Firefox Download Day To Start At 1 p.m. EST 1080

boustrophedon writes "Starting at midnight in their local timezones, downloaders have been asking when Firefox 3 will be ready for Firefox Download Day, June 17, 2008. Mary announced on the Spread Firefox Forum that downloads will commence at 10 AM PST." That means 1 p.m. East Coast time, and, in Justin Mason's view, some pretty annoying times of day for many parts of the world. Reader CorinneI supplies a link to PC Magazine's (very positive) overview of the new version's features, which praises the "speedy performance, thrifty memory usage, and, in particular, the address bar that now predicts where you want to go when you start typing (what Mozilla insiders refer to as the Awesome Bar)." FF3, even in Beta and RC form, and even with the extension incompatibilities I've run into, has quickly replaced FF2 as my preferred browser — for me, the improved drop-down autocomplete behavior alone is enough to justify the switch.

Do Women Write Better Code? 847

JCWDenton writes "The senior vice-president of engineering for computer-database company Ingres-and one of Silicon Valley's highest-ranking female programmers-insists that men and women write code differently. Women are more touchy-feely and considerate of those who will use the code later, she says. They'll intersperse their code ... with helpful comments and directions, explaining why they wrote the lines the way they did and exactly how they did it. The code becomes a type of 'roadmap' for others who might want to alter it or add to it later, says McGrattan, a native of Ireland who has been with Ingres since 1992. Men, on the other hand, have no such pretenses. Often, 'they try to show how clever they are by writing very cryptic code,' she tells the Business Technology Blog. 'They try to obfuscate things in the code,' and don't leave clear directions for people using it later. "

Cat Ownership Correlated With Heart Health 406

Ant tips us to a story making the rounds lately, based on reporting a couple of weeks old, that owning a cat could cut your heart attack risk by one third. No such effect was seen from dog ownership, but the researchers say that could be because there weren't enough dog owners in the study population to provide meaningful statistics. The study: "...analyzed data on 4,435 Americans, aged 30 to 75, who took part in the federal government's second National Health and Nutrition Examination Study, which ran from 1976-1980. According to the data in the survey, 2,435 of the participants either owned a cat or had owned a cat in the past, while the remaining 2,000 had never done so. [The] team then tracked rates of death from all causes, including heart and stroke. Cat owners 'appeared to have a lower rate of dying from heart attacks' over 10 years of follow-up compared to feline-free folk..."

UK Report Slams EULAs 239

draevil writes "Britain's National Consumer Council has completed an investigation into the practice of software End User License Agreements(EULAs) with the conclusion that many consumers are signing away their legal rights and agreeing to unfair terms, which they could never have scrutinized before purchase. The report also acknowledges that even if the EULA were available prior to purchase, it would be unreasonable to expect an average consumer to understand the terms to which they were agreeing. Here are the full report (PDF) and a summary." The NCC recommends that the European Commission bring softwre licenses under the same consumer protections that apply to other products in the EU.

Multifunction Printers — The Forgotten Security Risk? 153

eweekhickins writes to share an article in eWeek highlighting the forgotten risks that a multifunction printer could possibly offer. Brendan O'Connor first called attention to the vulnerabilities of these new devices at a Black Hat talk in '06 and warns that these are no longer "dumb" machine sitting in the corner and should be treated with their own respective security strategy. "During his Black Hat presentation in 2006, O'Connor picked apart the security model of a Xerox WorkCentre MFP, showing how the device operated more like a low-end server or workstation than a copier or printer--complete with an AMD processor, 256MB of SDRAM and an 80GB hard drive and running Linux, Apache and PostGreSQL. He showed how the authentication on the device's Web interface can be easily bypassed to launch commands to completely hijack a new Xerox WorkCentre machine."

Microsoft Insider Details Xbox 360 Red Ring Problems 415

kylemonger writes "A blogger at the Seattle PI has interviewed a Microsoft insider about the Xbox 360 project. The insider purports to have the background story on the 'red ring of death' (RROD) failures and why they are so common. 'RROD is caused by anything that fails in the "digital backbone" on the mother board. Also known as a core digital error. CPU, GPU, memory, etc. Bad parts, incompatible parts (timing problems) bad manufacturing process (like solder joints), misapplied heat sinks or thermal interface material, missing parts, broken parts, parts of the wrong value, missed test coverage. Any one or more, on any chip, or many other discrete components, would cause this. And many of the failures were obviously infant mortality, where they work when they leave the factory and fail early in use. The main design flaw was the excessive heat on the GPU warping the mother board around it. This would stress the solder joints on the GPU and any bad joints would then fail in early life. There are also other significantly high failure rates in other areas, like the DVD.'"

Do Any Companies Power Down at Night? 646

An anonymous reader writes "My Health Sciences Campus has about 8,000 desktop computers, and on any given night about half of them are left on. I know this because I track all the MAC addresses in case there is a virus outbreak. Aside from the current fad of 'being green', has anyone had any success in encouraging users to power-down at night? You could potentially eliminate running bots, protect yourself from the next virus outbreak, keep your data safe, etc. Do security concerns and power consumption issues matter enough to do this?"

Science Text Attempts to Reconcile Religion and Science 1071

terrymaster69 writes "The New York Times reports that the National Academy of Sciences has just published their third book outlining guidelines for the teaching of evolution. 'But this volume is unusual, people who worked on it say, because it is intended specifically for the lay public and because it devotes much of its space to explaining the differences between science and religion, and asserting that acceptance of evolution does not require abandoning belief in God.'"
