Schneider Electric announces Edge Module for IoT processing

Schneider Electric is the latest player to jump into the edge computing game for Internet of Things (IoT) devices with the announcement of its Edge Module for mobile and IoT applications. It follows the trend of processing IoT data where it is generated rather than sending it to a remote data center.Schneider Electric is a European giant that mostly specializes in energy management and power systems. So, it’s no surprise that the Edge Module comes with integrated power and cooling systems. That includes single- or three-phase power with a flexible power train in multiple ranges, N+1 standard cooling, and package cooling units mounted on the outside of the module to eliminate the need for external condensers or piping.To read this article in full, please click here

Visually Impaired Students in Rwanda Get a New Chance

Jacqueline is attending S4 secondary school HVP Gatagara. She used to read well, but when she reached primary five she went blind and started using audios.

“Studying with audios was challenging” she explains. “Sometimes I got bored and fell asleep. As time went by, I got experienced and I was able to pass my national examination regardless of my blindness.”

A project led by The Internet Society Rwanda Chapter and supported by Beyond the Net Funding Programme is implementing a breakthrough solution that will impact Rwanda’s education sector, addressing the urgent need of a functional learning environment for the visually impaired students.Visual impaired people are not aware of benefits they can get from the Internet. Awareness of what is possible and what is already available is crucial especially for blind students. Young Jacqueline believes that big things have small beginnings and that the Internet will give all students a better opportunity for a successful education: “We have a lot of books here, but we can’t take them home as others do. My request is to turn these books into audios and make them accessible to allow me and my classmates to keep on studying.”

A project called Continue reading

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

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
