It's been the case for every SQL database in practical use since E. F. Codd first came up with the concept: Records either exist or they don't. When you run a SELECT statement, you're querying the current state of the data. A state is either true or false.

Android applications downloaded by as many as 185 million users can expose end users' online banking and social networking credentials, e-mail and instant-messaging contents because the programs use inadequate encryption protections, computer scientists have found. The researchers identified 41 applications in Google's Play Market that leaked sensitive data as it traveled between handsets running the Ice Cream Sandwich version of Android and webservers for banks and other online services. By connecting the devices to a local area network that used a variety of well-known exploits, some of them available online, the scientists were able to defeat the secure sockets layer and transport layer security protocols implemented by the apps. Their research paper didn't identify the programs, except to say they have been downloaded from 39.5 million and 185 million times, based on Google statistics.

PopFab is a multi-tool for the 21st century. At its heart is a computer-controlled motion platform and a means of attaching various toolheads. These enable PopFab to make objects from a digital plan in a variety of ways: current capabilities include 3D printing (as you are about to see), milling, vinyl cutting, and drawing - with more on the way. PopFab has traveled the world as a carry-on item of luggage to Saudi Arabia and Germany, and within the USA to Aspen in Colorado. We hope that this is only the beginning.

The Yomiuri Shimbun It may be possible to travel to space in an elevator as early as 2050, a major construction company has announced. Obayashi Corp., headquartered in Tokyo, on Monday unveiled a project to build a gigantic elevator that would transport passengers to a station 36,000 kilometers above the Earth. For the envisaged project, the company would utilize carbon nanotubes, which are 20 times stronger than steel, to produce cables for the space elevator.

It's impossible to grasp the consequences or outcomes of new technology, especially when that technology is developed by a twenty-something hacker. That much was already clear in January 2010, when Mark Zuckerberg told TechCrunch founder Michael Arrington that Facebook isn't just a place to connect with your friends. It was a place to be more public than ever before. "People have really gotten comfortable not only sharing more information and different kinds, but more openly and with more people. That social norm is just something that has evolved over time," he said. "But we viewed that as a really important thing, to always keep a beginner's mind and what would we do if we were starting the company now and we decided that these would be the social norms now and we just went for it."
