Facebook Changes Privacy Policies, Scraps User Voting

Facebook

Orome1 writes “The voting period for the proposed changes to Facebook’s Statement of Rights and Responsibilities and Data Use Policy has ended on Monday, and despite the email sent out to the users asking them to review the changes and cast their vote, less than one percent of all users have done so. ‘An external auditor has reviewed and confirmed the final results. Of the 668,872 people who voted, 589,141 recommended we keep our existing SRR and Data Use Policy,”‘stated Elliot Schrage , Facebook’s vice president of communications, public policy, and marketing. Still, that is not nearly enough to prevent the proposed changes — as required by Facebook, at least 30 percent of the users should have voted against them in order to keep the previous versions of the policies. Schrage pointed out that that the whole experience illustrated the clear value of Facebook’s notice and comment process.”

How Data Center Operator IPR Survived Sandy

Data Storage

Nerval’s Lobster writes “At the end of October, Hurricane Sandy struck the eastern seaboard of the United States, leaving massive amounts of property damage in its wake. Data center operators in Sandy’s path were forced to take extreme measures to keep their systems up and running. While flooding and winds knocked some of them out of commission, others managed to keep their infrastructure online until the crisis passed. In our previous interview, we spoke with CoreSite, a Manhattan-based data center that endured even as much of New York City went without power. For this installment, Slashdot Datacenter sat down with executives from IPR, which operates two data centers—in Wilmington, Delaware and Reading, Pennsylvania—close to Sandy’s track as it made landfall over New Jersey and pushed northwest.”

Visi.io

Visi.io comes from David Pollak and aims at revolutionizing building tablet apps, but the main attraction now seems to be in exploring the way data flow and cloud computing can be integrated. The screencast is somewhat underwhelming but at least convinces me that there is a working prototype (I haven’t looked further than the website as yet). The vision document has some nice ideas. Visi.io came up recently in the discussion of the future of spreadsheets.

Green Grid Argues That Data Centers Can Lose the Chillers

Nerval’s Lobster writes “The Green Grid, a nonprofit organization dedicated to making IT infrastructures and data centers more energy-efficient, is making the case that data center operators are operating their facilities in too conservative a fashion. Rather than rely on mechanical chillers, it argues in a new white paper (PDF), data centers can reduce power consumption via a higher inlet temperature of 20 degrees C. Green Grid originally recommended that data center operators build to the ASHRAE A2 specifications: 10 to 35 degrees C (dry-bulb temperature) and between 20 to 80 percent humidity. But the paper also presented data that a range of between 20 and 35 degrees C was acceptable. Data centers have traditionally included chillers, mechanical cooling devices designed to lower the inlet temperature. Cooling the air, according to what the paper originally called anecdotal evidence, lowered the number of server failures that a data center experienced each year. But chilling the air also added additional costs, and PUE numbers would go up as a result.”

An anonymous reader writes “The details of a Canadian spying case are coming to light, including the method of copying the sensitive data from the ‘secured’ computer linking five countries and the Russian handlers: Copy Data into Notepad; Save File to Floppy Drive; USB Key; ???; Profit! For $3000/mo in prepaid credit cards and wire transfers.”

Data Breach Reveals 100k IEEE.org Members’ Plaintext Passwords

Security

First time accepted submitter radudragusin writes “IEEE suffered a data breach which I discovered on September 18. For a few days I was uncertain what to do with the information and the data. Yesterday I let them know, and they fixed (at least partially) the problem. The usernames and passwords kept in plaintext were publicly available on their FTP server for at least one month prior to my discovery. Among the almost 100.000 compromised users are Apple, Google, IBM, Oracle and Samsung employees, as well as researchers from NASA, Stanford and many other places. I did not and will not make the raw data available, but I took the liberty to analyse it briefly.”

How Internet Data Centers Waste Power

September 23rd, 2012 09:28 admin View Comments

Power

Rick Zeman writes “The New York Times has extensively surveyed and analyzed data center power usage and patterns. At their behest, the consulting firm McKinsey & Company analyzed energy use by data centers and found that, on average they were using only 6 percent to 12 percent of the electricity powering their servers to perform computations. The rest was essentially used to keep servers idling and ready in case of a surge in activity that could slow or crash their operations. ‘Worldwide, the digital warehouses use about 30 billion watts of electricity, roughly equivalent to the output of 30 nuclear power plants.’ In other words, ‘A single data center can take more power than a medium-size town.’ This is the price being paid to ensure everyone has instant access to every email they’ve ever received, or for their instant Facebook status update. Data Center providers are finding that they can’t rack servers fast enough to provide for users’ needs: A few companies say they are using extensively re-engineered software and cooling systems to decrease wasted power. Among them are Facebook and Google, which also have redesigned their hardware. Still, according to recent disclosures, Google’s data centers consume nearly 300 million watts and Facebook’s about 60 million watts. Many of these solutions are readily available, but in a risk-averse industry, most companies have been reluctant to make wholesale change, according to industry experts.”
