Ask Slashdot: Building A Server Rack Into a New Home?

Ask Slashdot: Building A Server Rack Into a New Home?:
jawtheshark writes "I'm building a house, and obviously I want a modest network built-in. Nothing fancy, two RJ-45 per room, four in the living room, and that's basically it. I already got myself a rack mountable Cisco Small Business switch and I have a self-built 4U server (low-power, won't make much heat) which can be rack mounted (505mm deep). Now, the construction company suggests a wall mounted rack (6U: 340mm x 600mm x 480mm — 6U definitely won't be enough, but a 12U model exists). It's not expensive, but I have never worked on a rack where the backside is unreachable. (For work, I get to work in a data center with huge racks that are accessible from both sides). Now obviously, I don't need a data center-grade rack, but these wall-mounted racks scream 'switch-only' racks to me. What are your experiences? Is it possible to put servers in racks like these, or should I find a 'both-side-accessible' rack instead?"

1 World Trade Center Becomes the Tallest Building In NYC

1 World Trade Center Becomes the Tallest Building In NYC:

darthcamaro writes "On 9/11, terrorists took the lives of thousands of Americans — and removed a pair of icons from the New York City skyline. For the last 10+ years, The Empire State Building was the tallest building in NYC, but that changed today. 'Poking into the sky, the first column of the 100th floor of 1 World Trade Center will bring the tower to a height of 1,271 feet, making it 21 feet higher than the Empire State Building.'"

Woman coughs up "tumor"

Woman coughs up "tumor":




Above left is 62-year-old Bianca Riveron's lung x-ray showing a block spot that physicians told her was likely cancer. For decades, she had suffered from a constant cough and difficulty breathing. A few months ago, she coughed up blood and the doctors noticed the dark mass in her lung. But after a second endoscopy, Riveron coughed up the "tumor." Best guess is that it was the pit of a nispero fruit that Riveron inhaled nearly thirty years ago. "Lung ''cancer'' may have been fruit pit from 1984" (WTSP)

Student's brain flatlined during classes

Student's brain flatlined during classes:


From "A Wearable Sensor for Unobtrusive, Long-term Assessment of Electrodermal Activity" (by Poh, M.Z., Swenson, N.C., Picard, R.W. in IEEE Transactions on Biomedical Engineering, vol.57, no.5), a chart showing a single student's electrodermal activity over the course of a week. Note the neural flatlining during classtime. As Joi Ito notes, "Note that the activity is higher during sleep than during class." He also adds, "Obviously, this is just one student and doesn't necessarily generalize."

Triggertrap: nine ways to activate your DSLR with an iOS device, choose one

Triggertrap: nine ways to activate your DSLR with an iOS device, choose one:

When we first heard about the Kickstarter-funded Triggertrap, it was a nice but nichey lab instrument of a device that could fire your DSLR with diverse stimuli, like lights or ringing phones. It wasn't the first photo-tripping idea we'd seen, but at least it could be had for a fair sum ($75.00) and be used out of the box. But now, by connecting that tech to an app and charging $19.98 for both the software and hardware, Triggertrap might open up remote snapping to a lot more folks.
Running off any iPhone, iPad or iPod using iOS 5, the app uses a dongle which can be connected by cable or infrared to most DSLRs or advanced compacts. From there, you'll be able to use all of your iDevice's sensors as triggers, from motion through to facial recognition and even GPS. The app doesn't just fire the shutter, either -- it also gives you control over the focus and flash. And if you don't have a separate camera, the iPhone's built-in cam can be used instead -- which would save you from buying the $9.99 dongle, if you have the necessary accoutrements. So if you've been wondering how to get those hard-to-shoot images, or have more nefarious ideas, check the videos after the break.

UK High Court rules ISPs to block Pirate Bay, forgets it ain't the boss anymore

UK High Court rules ISPs to block Pirate Bay, forgets it ain't the boss anymore:

The High Court has ruled that British ISPs must block web-browsing citizens from accessing the infamous Pirate Bay. The controversial ruling comes just six months after the European Court of Justice (a superior court) declared that companies like Sky and TalkTalk were protected against injunctions to block, filter or monitor internet traffic for that purpose. Virgin Media told the BBC that it would comply, before sensibly adding that censorship measures like this are ineffective in the long term.

PSA: Space X streaming test-firing of Falcon 9 at 2:30pm ET / 11:30am PT (update: video):

Today, SpaceX is test-firing the engines of its Falcon 9 rocket in preparation for that oft-delayed May 7th launch for its Dragon capsule. You'll be able to watch the static-fire test from the comfort of your own desk by pointing a browser at the company website (link below) from 2:30pm ET / 11:30am PT. If successful, then the rocket will lift-off properly in a week's time, with designs on being the first commercial craft used to resupply the International Space Station.
Update: For those who missed the live stream, you can check out a replay of today's event just after the break.

New Study Suggests Wind Farms Can Cause Climate Change

New Study Suggests Wind Farms Can Cause Climate Change:
nachiketas writes "A study led by Liming Zhou, Research Associate Professor at the Department of Atmospheric and Environmental Sciences at the University of New York concludes that large wind farms could noticeably impact local weather patterns. According to Professor Zhou: 'While converting wind's kinetic energy into electricity, wind turbines modify surface-atmosphere exchanges and transfer of energy, momentum, mass and moisture within the atmosphere. These changes, if spatially large enough, might have noticeable impacts on local to regional weather and climate.'"

How Apple Sidesteps Billions In Global Taxes

How Apple Sidesteps Billions In Global Taxes:

An anonymous reader writes "An article at the NY Times explains the how the most profitable tech company in the world becomes even more profitable by finding ways to avoid or minimize taxes. Quoting: 'Apple's headquarters are in Cupertino, Calif. By putting an office in Reno, just 200 miles away, to collect and invest the company's profits, Apple sidesteps state income taxes on some of those gains. California's corporate tax rate is 8.84 percent. Nevada's? Zero. ... As it has in Nevada, Apple has created subsidiaries in low-tax places like Ireland, the Netherlands, Luxembourg and the British Virgin Islands — some little more than a letterbox or an anonymous office — that help cut the taxes it pays around the world. ... Without such tactics, Apple's federal tax bill in the United States most likely would have been $2.4 billion higher last year, according to a recent study (PDF) by a former Treasury Department economist, Martin A. Sullivan. As it stands, the company paid cash taxes of $3.3 billion around the world on its reported profits of $34.2 billion last year, a tax rate of 9.8 percent."

The Math Formula That Lead To the Financial Crash

The Math Formula That Lead To the Financial Crash:

New submitter jools33 writes "The BBC has a fascinating story about how a mathematical formula revolutionized the world of finance — and ultimately could have been responsible for its downfall. The Black-Scholes mathematical model, introduced in the 70s, opened up the world of options, futures, and derivatives trading in a way that nothing before or since has accomplished. Its phenomenal success and widespread adoption lead to Myron Scholes winning a Nobel prize in economics. Yet the widespread adoption of the model may have been responsible for the financial crisis of the past few years. It's interesting to ponder how algorithms and formulas that we work on today could fundamentally influence humanity's future."
