1024-bit RSA encryption cracked by carefully starving CPU of electricity

Since 1977, RSA public-key encryption has protected privacy and verified authenticity when using computers, gadgets and web browsers around the globe, with only the most brutish of brute force efforts (and 1,500 years of processing time) felling its 768-bit variety earlier this year. Now, three eggheads (or Wolverines, as it were) at the University of Michigan claim they can break it simply by tweaking a device’s power supply. By fluctuating the voltage to the CPU such that it generated a single hardware error per clock cycle, they found that they could cause the server to flip single bits of the private key at a time, allowing them to slowly piece together the password. With a small cluster of 81 Pentium 4 chips and 104 hours of processing time, they were able to successfully hack 1024-bit encryption in OpenSSL on a SPARC-based system, without damaging the computer, leaving a single trace or ending human life as we know it. That’s why they’re presenting a paper at the Design, Automation and Test conference this week in Europe, and that’s why — until RSA hopefully fixes the flaw — you should keep a close eye on your server room’s power supply.

Windows only: Free application Tableau Public creates beautiful visualizations from your data and lets you publish them to the web, where users can interact with your charts and graphs with live updates.
The video above provides a great overview of how the tool works. Essentially, you import your data into the desktop Windows application, then play around with different charts, graphs, or other options until you find the visualization or visualizations that best fit your data. When you’re happy with what you’ve put together, you can save the outcome to the web, which uploads the charts to the Tableau Public servers. From there you can embed it on any web page YouTube-style), and users can drill down into the data to their heart’s content.
Here’s an example of Tableau Public in action from a post on the Wall Street Journal:
Tableau Public is a free download for Windows, and looks like a great tool to try out next time you’re looking to make your otherwise boring data come to life. Update: Somehow I managed to miss the fact that Tableau Public is only free on a trial basis; its actual price tag is extremely hefty. (Though if you’re a student you can get it for as little as $69.)
Double Update: Actually, looks like Tableau Public is free after all! Straight from the horse’s mouth:
“People can download the free tool and publish their visualizations of their data for free. Tableau Public includes a free desktop product that you can download and use to publish interactive data visualizations to the web. The Tableau Public desktop saves work to the Tableau Public web servers – nothing is saved locally on your computer. All data saved to Tableau Public will be accessible by everyone on the internet, so be sure to work only with [publicly] available (and appropriate) data.
When people want to analyze their private or confidential data (particularly data in data warehouses and other large databases), then they may want to consider our commercial products.”
Apple vs Microsoft vs Sony [Graphs]
The core of any long-standing technology company is research and development. Here’s how Apple, Microsoft and Sony’s last decade of spending stack up.
Note that the first graph shows research and development as a percentage of revenue (to scale the spending by company, since revenues differ so greatly). This next graphic can help you conceptualize the revenue and R&D gap:

A Few Interesting Notes:
• Now, Microsoft spends about 17% of their revenue on R&D. Sony spends about 8%. Apple spends less than 4%.
• If you were to break down the amount of R&D that goes purely to physical (non-software) products sold by Apple and Sony, Sony would spend about $11.5 million per product while Apple would spend about $78.5 million per product. (Of course, that’s rolling the cost OS X and iPhone OS development into Macs and the iPhone, which could be seen as inflating their per product spending.)
• Microsoft just spends a lot of money in R&D, period—about $9 billion last year in generalized research (that often doesn’t lead to specific products). In terms of percentage growth over the last decade, Apple’s R&D has grown the most (nearly quadrupled) while Sony’s has grown the least (not quite doubled).
In light of these bare numbers, is it any surprise that Sony is struggling the most to capture the hearts and minds of a public hungry for gadgets?

This Is Why that Amazing NASA Earth Image Looked So Familiar
After publishing the The Most Accurate, Highest Resolution Earth View to Date, it got extremely popular: The day after, countless newspapers and blogs worldwide reposted the story. NASA wrote to us, surprised. Why? Because everyone already knew about it:

Yes, the Blue Marble is the iPhone’s default screen, which have been seen by millions of iPhone owners and by everyone who has read about the iPhone since 2007. In fact, the image has been public since 2002:
From: *************** <***********@nasa.gov>
Mr. Diaz
Hello. I am the photo editor for the Public Affairs Office at NASA’s Goddard Space Flight Center.
We were happy to see you featured our Blue Marble image on your website last week.
http://gizmodo.com/5478787/the-most-accurate-highest-resolution-earth-view-to-date#comments
We also featured it on our Flickr page but it has really taken off on the web. We had over 500,000 hits in the last two days alone.
Given that this is an image from 2002 I’m just curious what prompted you to post it on your site? Or did you pick it up from someplace other than our site? I see at the bottom it says “NASA via Twitter”
Really, I’m just curious because it’s gotten so much play over that few days.
Thank you for your interest in our work.
Take care,
Rebecca
The reason? Because it’s a beautiful image, that’s all. One that makes you marvel at the beauty of our planet, and how tiny and insignificant we are, but also how unique and rare. [Gizmodo—Thanks to John Hermann for telling me about the obvious]
Don’t forget to check NASA Goddard’s Flickr page. They keep posting really cool stuff.

If you’re in the military, here’s a tip: don’t put upcoming missions in your Facebook status. You wouldn’t think someone would need to tell you that, but here we are.
A raid on suspected militants in the West Bank was cancelled yesterday after an Israeli soldier updated his Facebook status to read “On Wednesday we clean up Qatanah, and on Thursday, god willing, we come home.” The solider has since, unsurprisingly, been relieved of combat duty for being a moron. He’ll also spend 10 days in prison for his update.
Trying to educate soldiers on the importance of not leaking classified info to Facebook, the Israel Defense Forces have started putting up new posters in bases:
In posters placed on military bases, a mock Facebook page shows the images of Iranian President Mahmoud Ahmadinejad, Syrian President Bashar Assad and Hezbollah leader Sheik Hassan Nasrallah. Below their pictures – and Facebook “friend requests” – reads the slogan: “You think that everyone is your friend?”
I really want to see one of those posters. Anyone in the IDF want to send us a picture? My email address is below. I won’t post it on Facebook, promise. [NY Times]
Please Euthanize This Big Boy Already – How Lack of Innovation Killed Another Giant
Not only did the shift towards digital communication cause a continuing decline in revenues, the lack of innovation caused the U.S. Postal Service to fall far behind able competitors like FedEx, UPS, etc. (lowering prices is not innovation; and delivering 3 days a week is not innovation either.) We are at a point now where if the USPS disappeared, consumers will shift their remaining habits towards digital and existing delivery competitors will (gladly) absorb the incremental business (because they already work the routes anyway, and can even lower prices due to extra volume).

March 4 (Bloomberg) — The U.S. Postal Service, facing a $238 billion budget deficit by 2020, should consider cutting delivery to as few as three days a week as the agency attempts to pare costs, a consulting firm said.
Those cuts are among changes McKinsey & Co. presented in a report this week at a postal conference in Washington. Options also included expanding business lines and restructuring retiree health benefits.

Online advertising company Permuto pulled data from the U.S. Census Bureau into a nice infographic comparing people’s purchasing habits in-store vs. online, and it got us wondering: What do you buy online vs. in stores?
(Click the image above for a closer look.)
According to the Census Bureau’s data, the old brick and mortar stores are still responsible for the majority of sales in most of the categories, save for a few notable categories, including books, clothing, and electronics. Since Lifehacker readers are a more tech-savvy crowd than most of the public, we’d guess you tend more toward the buy online crowd. Are you more of a virtual shopper, or do you still prefer to touch and feel before you buy? It certainly varies depending on what you’re buying, so tell us about it in the comments.
The iPod Touch Is This Generation’s Tamagotchi

All these wonderful things we’re learning today, from data! First, we find out that Android is a guy thing. Now, we discover that the iPod Touch shares more demographics with glittering vampires than smartphones. iPod Touch: Kid stuff.
The age distribution makes a lot of sense, especially with the direct available comparison of the iPhone: the iPod Touch is a good gift, a plausible purchase, and a good investment for a young person right now. An iPhone with a $70-a-month minimum contract is a tougher sell, either to parents, or to kids mostly supported by their parents.
And these kids don’t just buy different gadgets than adults—they use them differently, too. For example, they looooove apps:
But they’re stingy little bastards, these kids: 
Buying an app can be tough without a credit card, so again, this isn’t shocking. But it does poke a little hole in the idea of the iPod Touch as a massive moneymaker for Apple. Hardware sales are tremendous and highly profitable, sure, but once the devices are in users’ soft little baby hands, they don’t keep raking it in like the iPhone does. [AdMob]
