TACC Tapped for NSF’s Next Supercomputer

The Texas Advanced Computer Center (TACC) will house the latest leadership-class supercomputer funded by the National Science Foundation, a project that stands as a tribute to the NSF’s continued efforts to push supercomputing projects and the latest indication of the ground the organization is losing to the Department of Energy (DOE) in this effort. …

Las Marías of Azacualpa: Internet for Raising Women’s Voices

Azacualpa Yamaranguila, a village in the Intibuca region in Honduras, is celebrating. And not for nothing. Last Saturday was a historic day as they accessed the Internet for the very first time. For many of us, the Internet is taken for granted, but for the Lenca people it started like a dream 6 months ago when the Internet Society Honduras’ Chapter gave them the idea of connecting their village to the Internet. This idea became a reality thanks to the collective effort of the community and the support of Beyond the Net.

Las Marías

The party is for everyone but it focuses on them: Las Marías. With great curiosity, the women of the community came to the celebration early.

When I arrived after a 4-hour trip from Tegucigalpa, they were already there, dressed in colorful clothing. They were selling their products, taking care of their children, and anxiously awaiting the inauguration of the first community network of Azacualpa.

It was also the first anniversary of the radio ‘La Voz de las Mujeres’ (‘The Voice of the Women’) and María Santos, one of the heroes of the day and a leader of the community, was the first Continue reading

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

Applying AI to Network Analytics

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

Worth Reading: The Jargon

One enduring and complex piece of jargon is the use of “free” in relation to software. In fact, the term is so ambiguous that different terms have evolved to describe some of the variants—open source, FOSS, and even phrases such as “free as in speech, not as in beer.” But surely this is a good thing, right? —Mike Bursell @Opensource.com
