To improve network throughput, scrap the ones-and-zeros system

Abandoning a signal’s traditional binary ones and zeroes will improve throughput in fiber, a Dutch PhD researcher says. By increasing the number of bit states from the traditional two — the one and zero — to four or eight, adding more light colors, and changing clock rates for each wavelength, throughput will be significantly increased, he claims.“A higher number of levels implies more information per symbol, so four levels contain two bits of information, and eight levels contain three bits,” says Robbert van der Linden in an article on the Eindhoven University of Technology Department of Electrical Engineering website.To read this article in full, please click here

IPv6 Paves Way to Boundless Mobility

Avoid Write-Only Code

You probably know that fantastic feeling when you think your newly-discovered tool is a Hammer of Thor, capable of solving every problem (or at least crashing through it). I guess you’re also familiar with that sinking feeling when you’re trying to use your beloved hammer to whitewash a bikeshed.

Not surprisingly, the cruder the tool is, the quicker you’ll hit its limits, like when you try to do data processing in Jinja2 (hint: don’t).

IDG Contributor Network: How to achieve and sustain peak performance in your data center

As Tom Brady once said, “if you don’t play to win, don’t play at all.” This mantra is reflected in Brady’s TB12 Method, a holistic lifecycle based on 12 principles that make up the optimal approach to exercise, training and living a life of vitality. It’s built on the premise of stopping an accident prior to it happening through pre-habitation and taking intelligent, strategic preventative measures. And while implementing all 12 principles is not required, their effect is cumulative: the more you can incorporate, the better your results will be.While this methodology applies to training superior athletes, data center managers have their own set of principles to ensure optimal data center performance. What we’ve dubbed the DCM10 Method, there are 10 fundamental steps every data center manager should use to evaluate their current data center and help transform its functionality. Similar to the TB12 Method, while not all of these steps are required to create a successful strategy, the more best practices applied will result in higher performance across the board.To read this article in full, please click here

Jazmin Fallas Kerr: Creating Opportunities for Women in Costa Rica

The age-old tradition of the physical marketplace may be crumbling, and many women-led families in Costa Rica are feeling the pinch. In fact, in Jazmin Fallas Kerr’s hometown, Desamparados, nearly half of all families with women as head of household are in poverty.

To combat that, Kerr made a digital bridge between creation and commerce. Hyena is an Internet-based marketplace which allows women artisans to sell their handiwork online for a fair price. The site now has more than 50 local women courting customers for their crafts. Kerr’s upbringing helped her develop the idea.

“I was inspired by my mother; she is a family leader and artisan,” Kerr said. “We are from an area of social vulnerability, and I know the difficulties these families face.”

The site helps solve a more universal problem. It gives women the flexibility and time to work outside of homemaking responsibilities.

“[I want to] empower women to create better opportunities for their families,” Kerr said. “It is being achieved through a platform involving different actors in society that involves from fair trade to online education.”

Winner of the “Creator of Digital Change” contest, Hyena exists thanks to that $3,000 prize money from the Continue reading

The Cybersecurity Tech Accord Fits Squarely in the Collaborative Security Approach

Last week at RSA, more than 30 global companies came together to sign the Cybersecurity Tech Accord “to protect and empower civilians online and to improve the security, stability and resilience of cyberspace.”  It is an example of collaboration, which demonstrates the commitment and focus of the signatory companies to take action in order to tackle the significant security threats we are currently facing. It is this type of collective action we have promoted as part of our collaborative security

The Tech Accord is a positive step by large corporations across the globe involved in security to come together in the name of collaboration and make security commitments that resonate with the demands of Internet users everywhere. Per the Accord’s website, there are four main tenets of the Tech Accord:

• Stronger defense
  The companies will mount a stronger defense against cyberattacks. As part of this, recognizing that everyone deserves protection, the companies pledged to protect all customers globally regardless of the motivation for attacks online.
• No offense
  The companies will not help governments launch cyberattacks against innocent citizens and enterprises, and will protect against tampering or exploitation of their products and services through every stage of technology development, design Continue reading

BrandPost: Analysys Mason Case Study of Windstream: Intelligent Multi-layer/Multi-domain Network Automation with SDN

Windstream made its SDN move by implementing Ciena’s Blue Planet to automate how it delivers wavelength services across its multi-vendor optical network -- setting the stage for the provider to virtualize network functions to enhance service activation and delivery times. Operational efficiency and customer experience are crucial to Windstream's success in the USA, but its heterogeneous network footprint can make network service provisioning and device configuration complex and costly. Building a programmable SDN-based network with Ciena's Blue Planet software is helping Windstream simplify operations, move to DevOps-centric processes, and create an extensible platform for new services.To read this article in full, please click here
