Facebook Putting Batteries On-Board Its Servers 155

1sockchuck writes "The data center of the future may have no central UPS units, and be filled with servers with on-board batteries. Facebook says it will adopt a new power distribution design that shifts the UPS and battery backup functions from the data center into the cabinet by adding a 12-volt battery to each server power supply, an approach pioneered by Google. Facebook says the move will slash its power bill and save millions in capital expenses on UPS systems and PDUs. Facebook acknowledged that these types of custom designs are limited to large companies, but called on server vendors and data center builders to adapt their offerings to make them available to smaller companies."

Dreamweaver Is Dying; Long Live Drupal! 318

Barence writes "Here's an interesting blog post by a designer who reckons Dreamweaver is dying. It's not Dreamweaver's fault, though. Nor is the problem Adobe and its development team — the last Dreamweaver CS4 version was the most impressive release in years. Moreover, although Microsoft Expression Web poses a far more credible threat than FrontPage could muster, Dreamweaver remains the best HTML/CSS page-based editor available. The real problem for Dreamweaver and for its users is that the nature of the web is changing dramatically."

Website Does Homework For Kids 166

A new French website allows children to pay older students to do their homework for them. Faismesdevoirs.com (domyhomework.com) allows children to buy answers to simple maths problems for 5 euros ($6), while a full end-of-year presentation complete with slides and speaking notes costs 80 euros ($100). Founder Stephane Boukris says, "I realized there was a gap in the market. Add to that a dose of insolence, a zest of arrogance and the internet, and you have faismesdevoirs.com." I thought cheating on homework was what older siblings were for.

Steve Bourne Talks About the History of Sh 232

An anonymous reader writes "Steve Bourne, the creator of the Bourne shell, or sh, talks about its history as the default Unix shell of Unix Version 7. Bourne worked on the shell in 1975 and said the process took no more than 6 months. Sh aimed to improve on the Thompson shell. 'I did change the shell so that command scripts could be used as filters. In the original shell this was not really feasible because the standard input for the executing script was the script itself. This change caused quite a disruption to the way people were used to working. I added variables, control flow and command substitution. The case statement allowed strings to be easily matched so that commands could decode their arguments and make decisions based on that. The for loop allowed iteration over a set of strings that were either explicit or by default the arguments that the command was given. I also added an additional quoting mechanism so that you could do variable substitutions within quotes. It was a significant redesign with some of the original flavor of the Thompson shell still there. Also I eliminated goto in favour of flow control primitives like if and for. This was also considered rather radical departure from the existing practice. Command substitution was something else I added because that gives you very general mechanism to do string processing; it allows you to get strings back from commands and use them as the text of the script as if you had typed it directly. I think this was a new idea that I, at least, had not seen in scripting languages, except perhaps LISP,' he says."

Firefox Beta Touts Advanced Engine, Solves 8 Flaws 493

nandemoari writes "Mozilla may be this year's winner in the 'browser battles' as they ready the next beta version of their tour-de-force, Firefox 3.1. Mozilla is resolving eight critical vulnerabilities found in the current version of Firefox — a move sure to garner applause from devoted Firefox users. As this year's crop of new browsers emerges, enhanced features are becoming secondary to one thing: speed. Mozilla is nearly ready to release the next beta version of Firefox 3.1 to the public for testing, and insiders predict that it will outpace even Safari 4, which has been the fastest browser in wide release since its beta began last week." It looks like they also will be upping the next major release to v3.5 to better show the significance of the release.

LEDs Lighting Up the African Darkness 182

Peace Corps Online writes "In a non-electrified society, life is defined by the sun and little is accomplished once it sets around 6 pm. Only 19 percent of rural areas in Ghana have electricity. The rest use foul-smelling kerosene lamps to light their huts, which pollute, provide little light and are major fire hazards. But now Philips has partnered with KITE, a not-for-profit Ghanaian organization, to bring artificial light to villages that have no electricity. The new Philips products include a portable lantern which provides bright white light where it is needed, the Dynamo Multi LED self-powered (wind-up) flashlight that provides 17 minutes of light from two minutes hand winding, and the 'My Reading Light,' which is a solar-powered reading light with built-in rechargeable battery. 'People can now do things in the evening,' says Harriette Amissah-Arthur, KITE's director. 'If you could only see the joy these products bring the villagers. You look at their faces; you have to see it to believe it.'"

Should Job Seekers Tell Employers To Quit Snooping? 681

onehitwonder writes in with a CIO opinion piece arguing that potential employees need to stand up to employers who snoop the Web for insights into their after-work activities, often disqualifying them as a result. "Employers are increasingly trolling the web for information about prospective employees that they can use in their hiring decisions. Consequently, career experts advise job seekers to not post any photos, opinions or information on blogs and social networking websites (like Slashdot) that a potential employer might find remotely off-putting. Instead of cautioning job seekers to censor their activity online, we job seekers and defenders of our civil liberties should tell employers to stop snooping and to stop judging our behavior outside of work, writes CIO.com Senior Online Editor Meridith Levinson. By basing professional hiring decisions on candidates' personal lives and beliefs, employers are effectively legislating people's behavior, and they're creating an online environment where people can't express their true beliefs, state their unvarnished opinions, be themselves, and that runs contrary to the free, communal ethos of the Web. Employers that exploit the Web to snoop into and judge people's personal lives infringe on everyone's privacy, and their actions verge on discrimination."

Smart Immigrants Going Home 770

olddotter writes "A 24-page paper on a reverse brain drain from the US back to home countries (PDF) is getting news coverage. Quoting: 'Our new paper, "America's Loss Is the World's Gain," finds that the vast majority of these returnees were relatively young. The average age was 30 for Indian returnees, and 33 for Chinese. They were highly educated, with degrees in management, technology, or science. Fifty-one percent of the Chinese held master's degrees and 41% had PhDs. Sixty-six percent of the Indians held a master's and 12.1% had PhDs. They were at very top of the educational distribution for these highly educated immigrant groups — precisely the kind of people who make the greatest contribution to the US economy and to business and job growth." Adding to the brain drain is a problem with slow US visa processing, since last November or so, that has been driving desirable students and scientists out of the country.

Linux Foundation Purchases Linux.com 231

darthcamaro and several other readers have noted that the Linux Foundation has bought Linux.com from SourceForge Inc. (Slashdot's corporate parent). The Linux Foundation (employer of Linus Torvalds) will take over the editorial and community stewardship for the site; SourceForge will continue to supply advertising on it. "[Linux Foundation Executive Director Jim] Zemlin says the Linux Foundation wants to build a collaborative forum where Linux users can share ideas and get information on the Linux operating system. A beta of the site will be released in the next few months. ... Linux.com is being redesigned as a central source for Linux software, documentation and answers regardless of platforms, including server, desktop/netbook, mobile and embedded areas." What do you think should be on Linux.com?

Collaborative Map-Reduce In the Browser 188

igrigorik writes "The generality and simplicity of Google's Map-Reduce is what makes it such a powerful tool. However, what if instead of using proprietary protocols we could crowd-source the CPU power of millions of users online every day? Javascript is the most widely deployed language — every browser can run it — and we could use it to push the job to the client. Then, all we would need is a browser and an HTTP server to power our self-assembling supercomputer (proof of concept + code). Imagine if all it took to join a compute job was to open a URL."
