That is the max draw. The operating draw for most devices that size is about 1/3rd the rating of the power supply. The same ratio is quite close for full sized PC power supplies. A 1000 watt power supply draws ~300. Maybe 350 while under load.

Your laptop likely draws 20watts while idle and 25 while operating at full load.

Nearly all home-sized solar panels (made by BP, Sharp, Sanyo, Sunpower, etc) come from very large, established companies. These panels all have *at-least* 25 year warranties that guarantee the panels will still generate 80% of their peak capacity at this time. A good number carry 30-year production warranties, and have for several decades.

I'd like to know where you got this information that the panels only last 10 years.

Those are just a start. I designed and manage a PV array that provides 25% of my company's energy consumption and offer's an 8 year financial payback - in rainy Seattle. Many solar manufacturers place their panels on the roofs of their factories to offset a portion of their electrical consumption.

Surprise, Windows Listed as Most Secure OS 499

Posted by Zonk from the opposite-day dept.
david_g17 writes "According to a Symantec study reported by Information Week, Microsoft has the most secure operating system amongst its commercial competitors. The report only covered the last 6 months of vulnerabilities and patch releases, but the results place Microsoft operating systems above Mac OS X and Red Hat. According to the article, 'The report found that Microsoft Windows had the fewest number of patches and the shortest average patch development time of the five operating systems it monitored in the last six months of 2006.' The article continues to mention the metrics used in the study (quantity and severity of vulnerabilities as well as the amount of time one must wait for the patch to be released)."

How To Make the DS Even Better 82

Posted by Zonk from the add-a-totally-wicked-spoiler dept.
Next Generation has up an interesting piece considering ways to make the ultra-successful Nintendo DS even better. Thoughts include streamlining the needlessly complicated 'friend code' system, adding internal flash ram to the device, and rolling out a virtual console system ala the Wii. Their best idea, I think, is to use the GBA slot on the system for a cartridge including all of these new elements: "The advantage over typical 'system upgrades', like the ram expansion for the N64 or the PS2 hard drive, is that this cartridge should have little direct effect on game software; it would simply transform the DS into a more useful and personal tool. Such an update would also weed out the necessity to offer a whole new DS model, further annoying people who felt forced to upgrade to the DS Lite - itself only a cosmetic adjustment."

Beyond the challenge of convincing consumers to buy a Zune, Microsoft faces a battle for public perception. When Google News thinks "Zune" is a typo and current iPod news stories online outnumber Zune stories 25-to-1, what can Microsoft do to get better press?"

Bill Gates, chairman of Microsoft, will speak at Harvard University's commencement ceremony in June and, like all commencement speakers, will receive an honorary degree from the institution. It's hard to guess if Gates, the wealthiest person in the world and co-founder of a company that brought in $44 billion in revenue last year, cares. But the programming whiz who once dropped out of Harvard will likely feel some sense of satisfaction. http://www.networkworld.com/news/2007/032207-bill- gates-to-finally-receive.html"

Submission + - Single human gene gives mice tri-color vision

Submitted by
maynard
maynard writes: "Scientists from Johns Hopkins University School of Medicine and Howard Hughes Medical Institute working in collaboration have published a study in the peer reviewed journal Science showing that mice transgenetically altered with a single human gene are then able to see in full tri-color vision. Mice without this alteration are normally colorblind. The scientists speculate that even mammalian brains from animals that have never evolved color vision are flexible enough to interpret new color sense information with just a simple addition of new photoreceptors. Such a result is also indicated by a dominant X chromosome mutation that allows for quad-color vision in some women. From the article:

The experiments were designed to determine whether the brains of the genetically altered mice could efficiently process sensory information from the new photoreceptors in their eyes. Among mammals, this more complex type of color vision has only been observed in primates, and therefore the brains of mice did not need to evolve to make these discriminations.


The new abilities of the genetically engineered mice indicate that the mammalian brain possesses a flexibility that permits a nearly instantaneous upgrade in the complexity of color vision, say the study's senior authors, Gerald Jacobs and Jeremy Nathans.

Submission + - Which IT careers are hot and which are not?

necromante writes: I've been working on different IT positions through my career: Support, some networking, DBA, web development, project management, even working on the client side for a little while. However I don't feel like I am really an specialist on any of those subjects and I feel I need to focus on a particular field. So I decided to ask Slahdot for some feedback before taking my decision. Is there any IT career that I should consider more than the others? Which are the emerging fields? Any industry in particular? Which careers on IT are actually more in demand and which ones not? Or is a better path to focus on moving into management? By the way, I am writing from Canada. I do understand that this also depends everyones tastes, likes and dislikes. However I would like to have a better idea of which are the available options. I hope the results of this discussion can benefit other Slashdot readers. Thank you for your time!

ICANN Set To Review Accreditation Policy 31

Posted by Zonk from the at-least-something-will-come-of-this dept.
tinkertim writes "ICANN is re-evaluating the scope and purpose of its accreditations, apparently sparked by the recent collapse of garage domain name registrar Registerfly. In a press release dated March 21, 2007, President and CEO of ICANN, Dr Paul Twomey is quoted as saying : 'What has happened to registrants with RegisterFly.com has made it clear there must be comprehensive review of the registrar accreditation process and the content of the RAA.' Dr. Twomey is blaming (in part) 'weaknesses in the RAA' for severe and undue hardships that many registrants encountered when trying to transfer names away from the failing registrar, Registerfly. Many new points to be discussed include allowing registrants to view the performance of registrars in an 'independent comparative way', as well as new language to allow ICANN to forcibly intercede in the face of wide spread, persistent and consistent complaints. 10 good points for discussion are listed by Dr. Twomey in the release, who invites all ICANN stakeholders to participate in re-evaluating the RAA. Registerfly, the catalyst for this re-write does not officially lose their accredited status until March 31, 2007, and continues to display the ICANN seal on their web site."
