Computing should be based on light, not electricity, scientists say

Light-carrying, miniature wires are potentially more efficient for computing than other forms of interconnects, including copper and larger optical systems, say experts.However, there’s been a problem in getting such a nanowire system to work, the University of North Carolina at Chapel Hill, explains in an article published on Science Daily.“There hasn't been a controlled method for selectively sending light down along nanoscale wires,” says James Cahoon, a professor in the College of Arts and Sciences. “Optical technology has either used much larger structures or wasted a lot of light in the process.” Creating light uses power, defeating the object, for one thing.To read this article in full, please click here

Duo's software as a service-based (SaaS) model will be integrated with Cisco ISE to extend ISE to provide cloud-delivered application access control. By verifying user and device trust, Duo will add trusted identity awareness into Cisco's Secure Internet Gateway, Cloud Access Security Broker, Enterprise Mobility Management, and several other cloud-delivered products. Cisco's in-depth visibility of over 180 million managed devices will be augmented by Duo's broad visibility of mobile and unmanaged devices. Cisco said that Integration of its network, device and cloud security platforms with Duo Security’s zero-trust authentication and access products will let customers to quickly secure users to any application on any networked device. In fact, about 75% of Duo’s customers are up and running in less than Continue reading

Why IoT for seniors is a lot tougher than it looks

We’ve all heard the promises about how the Internet of Things (IoT) is perfectly positioned to provide healthcare, entertainment, and a wide variety of other services to the aging populations of many industrialized nations. The need is real because the population of countries like Japan, Italy, Greece, and Germany are getting older fast, resulting in a dearth of youngsters able (and willing, of course) to take care of their parents’ generation.The idea — bolstered by a European Commission on the topic — is that autonomous devices, robots, built-in sensors, medical and fitness wearables, voice-activated assistants, specially tuned smart homes, and other IoT innovations will fill in the gaps, helping meet the needs of seniors without requiring legions of younger workers. But when I saw a recent CNBC story about Google’s Nest home automation unit exploring the senior citizen market, it made me laugh out loud.To read this article in full, please click here

Skydive With oVirt

Skydive network is an open source real-time network topology and protocols analyzer providing a comprehensive way of understanding what is happening in your network infrastructure. The common use cases will be, troubleshooting, monitoring, SDN integration and much more. It has features such as:

  • Topology capturing - Captures network topology, interface, bridge and more
  • Flow capture - Distributed probe, L2-L4 classifier, GRE, VXLAN, GENEVE, MPLS/GRE, MPLS/UDP tunnelling support
  • Extendable - Support for external SDN Controllers or container based infrastructure, OpenStack. Supports extensions through API

Benefit to oVirt users

Skydive allows oVirt administrators to see the network configuration and topology of their oVirt cluster. Administrators can capture traffic from VM1 to VM2 or monitor the traffic between VMs or hosts. Skydive can generate traffic between 2 running VMs on different hosts and then analyze. Administrators can create alerts in Skydive UI to notify when traffic is disconnected or down.

Installation steps

  1. git clone https://github.com/skydive-project/skydive.git

  2. Create inventory file

SSDs poised to get a lot cheaper

If you are SSD shopping for your servers, you might want to wait a little because a market research firm that follows this sector said conditions are ripe for price drops in the coming months.DRAMeXchange, a division of market research firm TrendForce, forecasts that the average selling prices (ASP) of NAND Flash will drop by around 10 percent quarter over quarter respectively in the third and fourth quarters of 2018.Usually Q3 is the time of peak demand as OEMs ramp up manufacturing for the Christmas holiday, but the growth of the end-market demand has been weaker than anticipated. At the same time, the supply of 3D-NAND Flash continues to expand.To read this article in full, please click here
