"We thought ten people would care; instead a million people read our Storage Pod 1.0 blog post where we open sourced the Backblaze Storage Pod design and introduced the world's most cost-efficient way to store big data. The interest grew when we published our Petabytes on a Budget: Revealing More Secrets blog post that announced Storage Pod 2.0, which doubled the amount of storage and reduced the price. Since then several companies have built businesses selling Storage Pods inspired by Backblaze to hundreds of organizations around the world who are storing hundreds of petabytes of data on their own Storage Pods. Today we introduce Backblaze Storage Pod 3.0 which stores more data, costs less, is more reliable, and is easier to service."

"In the Harry Potter world, Ravenclaws are known for being the smart ones. That's their thing. In fact, that was really all they were known for. In the books, each house could be boiled down to one or two words: Gryffindors are brave, Ravenclaws are smart, Slytherins are evil and/or racist, and Hufflepuffs are pathetic loyal. (Giving rise to this hilarious Second City mockery.)"

"On Saturday, around 18 months after President Obama signed it into law, the Leahy-Smith America Invents Act will take effect. Ostensibly, the act is designed to bring U.S. patent law in line with the rest of the world. Of course, not everybody feels it will help achieve the patent system's goal of protecting inventors while fostering innovation, and its effect could be even more pronounced on the DIY inventor."

"If there was a single nerdy subtext that Bill Gates brought to his closing keynote at the SXSWedu conference in Austin, it was the importance of data. Useful data. Education data."

"In recent years, researchers in the messy world of biology have been able to build systems that function like the clean, binary switches on computer chips-and we've covered a number of reports in this area. Unfortunately, most of these share a significant limitation: they rely on proteins from bacteria that act as switches to turn genes on and off under specific conditions. We know about only a limited number of these genetic switches, which may set a severe limit on the number of logical operations we can string together inside a cell."

The march of science is stumbling and easily sidetracked, fraught with bias, fads and dead ends. A new research initiative based at the University of Chicago and the Computation Institute will use the latest computational tools to scrutinize this imperfect path and better understand how knowledge was and is created. Such understanding could transform the process of research, calling out past missteps while revealing unanticipated new directions for the future.

"Security researchers warn that cybercriminals have started using Java exploits signed with digital certificates to trick users into allowing the malicious code to run inside browsers. A signed Java exploit was discovered Monday on a website belonging to the Chemnitz University of Technology in Germany that was infected with a Web exploit toolkit called g01pack, security researcher Eric Romang said Tuesday in a blog post. "

Last week as part of its glitzy annual conference in Long Beach, California, TED awarded its $1 million prize to Sugata Mitra to support his wish to build a "School in the Cloud," a self-organized learning environment based on his "Hole in the Wall" and "Granny Cloud" research. Next week Pearson, the largest and most powerful education company in the world, will publish Dale Stephens' book Hacking Your Education: Ditch the Lectures, Save Tens of Thousands, and Learn More Than Your Peers Ever Will, a personal experience narrative and guide about dropping out of college and making it in Silicon Valley.

"The global pattern of e-mail communication reflects the cultural fault lines thought to determine future conflict, say computational social scientists."

"The issue of wealth inequality across the United States is well known, but this video shows you the extent of that imbalance in dramatic and graphic fashion. The video, which started going viral on Friday and whose traffic continues to climb on YouTube - reflects the facts as seen from many different sources. We present it without comment, letting you, our readers, be the judge."

"It is a wonder that we have yet to officially write about probability theory on this blog. Probability theory underlies a huge portion of artificial intelligence, machine learning, and statistics, and a number of our future posts will rely on the ideas and terminology we lay out in this post. Our first formal theory of machine learning will be deeply ingrained in probability theory, we will derive and analyze probabilistic learning algorithms, and our entire treatment of mathematical finance will be framed in terms of random variables."

"A brain-to-brain interface (BTBI) enabled a real-time transfer of behaviorally meaningful sensorimotor information between the brains of two rats. In this BTBI, an "encoder" rat performed sensorimotor tasks that required it to select from two choices of tactile or visual stimuli. While the encoder rat performed the task, samples of its cortical activity were transmitted to matching cortical areas of a "decoder" rat using intracortical microstimulation (ICMS). The decoder rat learned to make similar behavioral selections, guided solely by the information provided by the encoder rat's brain. These results demonstrated that a complex system was formed by coupling the animals' brains, suggesting that BTBIs can enable dyads or networks of animal's brains to exchange, process, and store information and, hence, serve as the basis for studies of novel types of social interaction and for biological computing devices."

It seems that more and more policy makers, advocacy groups, advertisers and media pundits are making claims based on science: this kind of potion is good for your health, that chemical is bad for the environment, this new technology can reduce crime. How is the public supposed to know what to believe?

CAVE2™, the next-generation large-scale virtual-reality environment, is a hybrid system that combines the benefits of both scalable-resolution display walls and virtual-reality systems to create a seamless 2D/3D environment that supports both information-rich analysis as well as virtual-reality simulation exploration at a resolution matching human visual acuity.

It's easy to get lost in CAVE2. The next-generation virtual reality platform is one of the most advanced visualization environments on Earth. It combines 320 degrees of panoramic, floor-to-ceiling LCD displays with an optical tracking interface that gives rise to a "hybrid reality system" capable of rendering remarkably immersive 3D environments - whether you wish to explore the labyrinthine vasculature of the human brain, or soar swiftly over the vast canyons of Mars.

"It may sound less likely than hell freezing over, but physicists have created an atomic gas with a sub-absolute-zero temperature for the first time. Their technique opens the door to generating negative-Kelvin materials and new quantum devices, and it could even help to solve a cosmological mystery."

The language we use affects the decisions we make, according to a new study. Participants made more rational decisions when money-related choices were posed in a foreign language that they had learned in a classroom setting than when they were asked in a native tongue.
