Windows 8 graphics: Microsoft has hardware accelerated all the things
Moving into specific changes made to DirectX 11.1, Microsoft has made it much better at redrawing portions of the screen, such as on YouTube, where only the video segment should be constantly re-rendered. By reducing redundant redrawing of text and other static elements, there is less memory and processor cycle wastage.
via Windows 8 graphics: Microsoft has hardware accelerated all the things | ExtremeTech.
In all cases, faster and more efficient rendering will result in less hardware resources being used, and thus lower power consumption. In the entire cycle of Windows 8, improved efficiency and battery life are probably the strongest and most recurring themes. If the unremovable Metro Start Screen and Surface tablets wasn’t proof enough, this laser-tight focus on efficiency makes it patently clear that Microsoft’s primary concern is being competitive against Google and Apple in the mobile computing sector.
Black Hat hacker gains access to 4 million hotel rooms with Arduino microcontroller
Bad news: With less than $50 of off-the-shelf hardware and a little bit of programming, it’s possible for a hacker to gain instant, untraceable access to millions of key card-protected hotel rooms.

Tatu Ylonen, father of SSH, says security is ‘getting worse’
I think it’s getting worse. Consumer privacy is disappearing totally. And SSL [Secure Sockets Layer] is being questioned and the problem isn’t the protocol itself but the key infrastructure. There have been several incidents where someone has stolen from the certificate authorities.

Welcome to SIPp
SIPp is a free Open Source test tool / traffic generator for the SIP protocol. It includes a few basic SipStone user agent scenarios (UAC and UAS) and establishes and releases multiple calls with the INVITE and BYE methods. It can also reads custom XML scenario files describing from very simple to complex call flows. It features the dynamic display of statistics about running tests (call rate, round trip delay, and message statistics), periodic CSV statistics dumps, TCP and UDP over multiple sockets or multiplexed with retransmission management and dynamically adjustable call rates.

Poison Attacks Against Machine Learning
With AI systems becoming more common, we have to start worrying about security. A network intrusion may be all the more serious if it is a neural net that is affected. New results indicate that it may be easier than we thought to provide data to a learning program that causes it to learn the wrong things.
