When the lights go out: How utilities can better assess the impact of outages on their network assets
Do you have access to real-time data and an end-to-end network view to know what network resources are impacted during a power outage?
By Mitch Simcoe – We’ve all seen this movie before. Back on July 13th, a power outage in New York City impacted 72,000 Manhattan customers (including shutting down Broadway on a Saturday night) which was attributed to an issue with the utility company’s relay protection system. The power grid’s protection system should have triggered a protection relay to isolate the faulty power line which ultimately led to the outage.
Yet as we enter the peak of summer heat in August, additional power outages continued to plague NYC this summer. A little over a week after the Manhattan blackout, 50,000 customers in Brooklyn and Queens lost their power as the temperature rose to above 90 degrees amid a brutal heat wave. “More than 30,000 customers had their juice deliberately cut by the utility thereby avoiding a much longer outage,” Con Ed spokesperson Allen Drury told Curbed at the time. Curbed also indicated that Con Ed had identified a ‘flawed connection’ as the cause of Manhattan’s major blackout.
As these power outages occur, and with more frequency lately, the first question to staff from utility management is: what resources, facilities and customers have been impacted by the outage?
In the world of Operational Technology/Information Technology (OT/IT) networking, how can utilities answer this question if they do not have a complete understanding of the resources underpinning their networks? To effectively manage their networks at the most basic level, utilities need an inventory system that accurately presents all available resources, both physical and virtual, end-to-end.

Reality-Defying Photo Composites Master the Impossible
By Jordan Kushins – Juan José Egúsquiza is based in Brooklyn, New York, but he spends much of his time as a man of the world. From Paris to San Francisco to Barcelona to Lucerne and beyond, the Lima, Peru-born multimedia artist and Adobe Creative Resident makes his way across the globe with his camera in hand. While exploring, he captures ordinary moments with a click, and these images become the basis for what he calls “Impossible Stories”: brain-bending composites that challenge the way we relate to and interpret our surroundings.
When I was young, I played music—percussion, mostly—and was in a band with my twin brother, who’s also an artist. He was so creative, and making things all the time, often grabbing trash and turning it into sculptures or instruments. That idea of recycling—of taking elements that were meant to be for something and then using them to build something else—was super, super cool to me. At some point I realized I wanted to start creating my own special things as well.
I was 19 or 20 when I first started taking pictures. I’d be traveling, mostly alone, and all of a sudden I’d be somewhere I’ve never been before: walking around, seeing new things, observing ordinary moments. I’ve always liked those the most; like, someone throwing a cookie away in a garbage can. Once you take a picture of it, it becomes something totally different.
At first, I wouldn’t edit my images at all, but eventually I started thinking: “What if I grabbed one element from this image and put it on something else?” Now that kind of photo compositing is a daily practice. more>

By Tom Nichols – I’m used to people disagreeing with me on lots of things. Principled, informed arguments are a sign of intellectual health and vitality in a democracy. I’m worried because we no longer have those kinds of arguments, just angry shouting matches.
I fear we are moving beyond a natural skepticism regarding expert claims to the death of the ideal of expertise itself: a Google-fueled, Wikipedia-based, blog-sodden collapse of any division between professionals and laypeople, teachers and students, knowers and wonderers—in other words, between those with achievement in an area and those with none. By the death of expertise, I do not mean the death of actual expert abilities, the knowledge of specific things that sets some people apart from others in various areas.
There will always be doctors and lawyers and engineers and other specialists. And most sane people go straight to them if they break a bone or get arrested or need to build a bridge. But that represents a kind of reliance on experts as technicians, the use of established knowledge as an off-the-shelf convenience as desired. “Stitch this cut in my leg, but don’t lecture me about my diet.”
The larger discussions, from what constitutes a nutritious diet to what actions will best further U.S. interests, require conversations between ordinary citizens and experts. But increasingly, citizens don’t want to have those conversations. Rather, they want to weigh in and have their opinions treated with deep respect and their preferences honored not on the strength of their arguments or on the evidence they present but based on their feelings, emotions, and whatever stray information they may have picked up here or there along the way.
This is a very bad thing. more>

Transforming the Capital Asset Lifecycle – Part 1
By John Lusty – “Innovate or die”. Three years ago, in the global oil & gas industry, this was the dire message communicated from the boardroom to the operating plant as falling commodity prices were hollowing out corporate income statements. The same story echoed through the supply chain as engineering contractors and equipment manufacturers fought for survival – trying to win enough work to remain healthy within a shrinking capital project market while creating greater value from the existing capital asset lifecycle.
The cost-cutting that ensued was ugly, and the job losses were substantial. In parallel, the appetite for innovative ideas sky-rocketed as producers worked to wring out costs and remain profitable at any price. This triggered a new behavior within the traditionally siloed energy industry, for the first-time visionaries started to look to other manufacturing industries for capabilities that could be adapted to their own companies.
What they saw was a shock. Despite years of investing in software and technology, capital asset owners in the energy and process industries still had a long way to go to get full value from their technical information compared to other, more mature, industries. Unlike their business information which, to a greater degree, had been consolidated following two decades of ERP implementations, the technical information supporting their plant assets was still scattered across different locations and incompatible file formats.
To make matters worse, data from multiple projects and facilities used software from a variety of vendors along with their own standards and specifications. Plants that came in through acquisitions and mergers were even more unique. more>

Photonic integration and co-packaging: Design tools for footprint optimization in data center networks
As traffic within and between data centers continues to grow, operators need to constrain the resulting increase in power consumption to minimize operational costs. This is driving the need to manage footprint and power at the system design level. Photonic integration and co-packaging are related approaches to addressing area and power challenges for networking applications.
By Patricia Bower – Data center networks have evolved rapidly over the last couple of years, in large part due to the scalability and flexibility supported by today’s compact modular DCI solutions. System designers leveraged advances in key foundational technologies to pack significant capacity and service density into these products, and their popularity is growing as these solutions capture new market segments.
The same advances have also paved the way for new consumption models for coherent optical technology in the form of footprint-optimized, pluggable solutions. As traffic growth for server interconnect within data centers continues to increase, greater for interconnect between data centers (DCI) will be required.
Scaling of data center traffic to get more bandwidth adds to the power consumption overhead and real estate requirements for operators which adds to capital and operational costs.
With each new generation of switching platform and coherent optical transport systems, designers have met the challenges by increasing throughput density and reducing power/bit. Both intra-DC and DCI traffic flows will increasingly rely on advances in foundational technologies and system design options to mitigate power consumption while maximizing interconnect densities.
What are these foundational technologies? They include:
- Complementary Metal-Oxide Semiconductor (CMOS)
- Indium phosphide (InP)
- Silicon photonics (SiPhot)
In networking applications, CMOS is the basis for both high-capacity switch chips used in router platforms and coherent optical digital-signal-processors (DSP).
InP and SiPhot are used to build electo-optical circuits for signal transport over optical fibers. Together, the DSP and electro-optical components are the heart of coherent optical transport systems. more>
