No matter how efficient we make our transistors and memory cells, they will always consume a fixed but tiny amount of energy set by the second law of thermodynamics, a new study suggests. Now the question is how close our real-world devices can get to this fundamental value. “At the end of the day, it confirms that Landauer’s theory seems to →

5 Major Hospital Hacks: Horror Stories from the Cybersecurity Frontlines article tells that real-world war, combatants typically don’t attack hospitals. In the cyber realm, hackers have no such scruples. “We’re attacked about every 7 seconds, 24 hours a day” Many computers and medical devices in hospitals are running ancient operating systems that are full of security holes. →
Whether they’re for sensors in artificial skin that demands flexibility or for wearable electronics where the circuits must withstand our sweat, silicon-based chips aren’t always up to the task. Now, an international research team has developed a way to fabricate flexible, water-loving logic circuits and sensors without the need of semiconductors. Instead, what the researchers have done is coat gold →

It’s coming, it’s really coming, and it’s going to be huuuuugggge! That was the message of the tech company executives keynoting the annual Open Compute Project Summit, held this week in San Jose, Calif. They were talking about data. A tsunami of data. More data than anybody—even in an era in which 300 hours of video →
The good news is that some of today’s most advanced technologies are cheap and easy to find, both online and on the shelves of major chain stores. That’s also the bad news, according to DARPA. Darpa Invites Techies to Turn Off-the-Shelf Products Into Weapons in New ‘Improv’ Challenge article tells that defense agency is nervous →

What ISPs Can See: Clarifying the technical landscape of the broadband privacy debate https://www.teamupturn.com/reports/2016/what-isps-can-see Truly pervasive encryption on the Internet is still a long way off. The fraction of total Internet traffic that’s encrypted is a poor proxy for the privacy interests of a typical user. Even with HTTPS, ISPs can still see the domains →
The idea for this posting started when I read New approaches to dominate in embedded development article. Then I found some ther related articles and here is the result: long article. Embedded devices, or embedded systems, are specialized computer systems that constitute components of larger electromechanical systems with which they interface. The advent of low-cost →
