As electrodes, the harvester uses a carbon nanomaterial called graphene, layered with modified human proteins. The electrodes collect energy from the human body, relay it to the harvester, which then stores it for later use. Because graphene sheets can be drawn in sheets as thin as a few atoms, this allows for the creation of utra-thin supercapacitors that could be used as alternatives to classic batteries. For example, the bio-friendly supercapacitors researchers created are thinner than a human hair, and are also flexible, moving and twisting with the human body.
The new material, made of silica-coated copper nanowires encased in a polymer matrix, encodes information not in states of charge but instead in states of resistance. By applying a small voltage, it can be switched between a state of high resistance, which stops electric current, and a state of low resistance, which allows current to flow. And, unlike silicon, the nanowires and the polymer can be dissolved in methanol, creating a liquid that can be sprayed through the nozzle of a printer.
Amazingly, its write speed is three microseconds, "rivaling the speed of flash drives." The information can be re-written many times, and the stored data can last for up to 10 years.
Nmap.org has a tradition -- the first person to notify them when new Nmap appears in a new movie wins a signed copy of Nmap Network Scanning "or a T-shirt of your choice from the Zero Day Clothing Nmap Store." (The site adds that "movie script writers, artists, and digital asset managers are also welcome to email Fyodor for advice.") And Nmap.org just added another film, Oliver Stone's new movie about Edward Snowden. In one early scene, Snowden is given a network security challenge at a CIA training class which is expected to take 5 to 8 hours. But with the help Nmap and a custom Nmap NSE script named ptest.nse, Snowden stuns the professor by completing everything in 38 minutes!
According to the site, even the movie's trailer features Nmap. Anybody else have their own favorite stories about code in the movies?
Ruby on Rails Creator and founder/CTO of Basecamp, David Heinemeier Hansson has responded to questions submitted by Slashdot readers. Read on for his answers.
While there's extensive material throughout the Internet on best practices for managing distributed teams, it seems to either take an agile perspective, the project manager's perspective or be otherwise based on the assumption that everyone in the team are working in the same project. In my case, I'd be managing a distributed team of developers all assigned to different projects. How can I build cohesion, alignment and trust for my team of embedded software developers in this new three-dimensional distributed matrix organization?
Anyone have any relevant experiences to share with distributed teams or "matrix" organizations? Leave your answers in the comments. How can you manage developers who are all distributed across multiple projects?
I have used the product "TestLog" which is a well-thought-out product; has test matrix capabilities (and other good features); however it does not have any integration with JIRA. (Hint, hint: Atlassian, this is what you need!).
Is there any company that makes a "plug-in" for JIRA with a similar features to TestLog – test case management that is well thought out, not just an afterthought?
