Virtualizing the World of Cable
By Wayne Hickey – When cable operators saw huge demands in linear video, Video-on-Demand (VoD) and high-speed data services, and faced with an aging analog infrastructure, they moved to a Converged Cable Access Platform (CCAP) to increase capacity and throughput. CCAP combines headend functions into a single architecture by combing Edge Quadrature Amplitude Modulation (EQAM) and Cable Modem Termination System (CMTS).

Back in June 2011, CableLabs created CCAP by blending two competing platforms, a Comcast-backed Converged Multiservice Access Platform (CMAP) and a Time Warner Cable Converged Edge Services Access Router (CESAR) platform. The following year CCAP products were introduced, and deployed the year after.

Fast forward to today, cable operators are looking to implement software-based access platforms, migrate away from commonly deployed centralized, purpose-built CCAP equipment, and virtualize CCAP (vCCAP) — and thus begin the shift to a Distributed Access Architecture (DAA). Developed by CableLabs, vCCAP is the latest cable technologies that combines functions including the CMTS and EQAM.

Virtualizing and distributing MAC and PHY functions enables digital combining, eliminates analog optics with cost effective 10G Ethernet transport, and converts analog fiber nodes to digital optic IP-enabled devices. DAA makes it easier to push fiber deeper into the edge of the network, and along with the ability to support denser wavelengths for each fiber, digital optics greatly improves Carrier-to-Noise-Ratio (CNR), which will enable higher orders of QAM on the coax and higher performance DOCSIS technologies. more> https://goo.gl/EoPwPL

The only job a robot couldn’t do

By Daniel Carter – The gig economy is growing rapidly, but it’s also changing how we think about what it means to work. Uber and other online platforms are making the case for a future in which work happens in little on-demand bursts — you need a ride, and someone appears to give you that ride. Instead of a salary and benefits like health insurance, the worker gets paid only for the time they’re actually driving you around.

I’m a researcher who studies how people work and I have a hard time endorsing this vision of the future. When I see Favor delivery drivers waiting to pick up a to-go order, I imagine a future in which half of us stand in line while the other half sit on couches. And then I imagine a future in which all these mundane tasks are automated: the cars drive themselves, the burritos fly in our windows on drones. And I wonder how companies are going to make money when there are no jobs and we can’t afford to buy a burrito or pay for a ride home from the bar. more> https://goo.gl/gXoUXd

Are Internet companies complicit in promoting hateful and harmful content?

By Hany Farid – In 2016, Facebook, Google, Microsoft, and Twitter announced that they would work together to develop new technology to quickly identify and remove extremism-related content from their platforms. Despite some progress, serious problems remain.

First, we need a fast and effective method to remove content. Once content has been identified, reported, and determined to be illegal or in violation of terms of service, it should be immediately removed (Prime Minister Theresa May is calling for a maximum of two hours from notification to take-down).

Fourth, we need to invest in human resources. While advances in machine learning hold promise, these technologies – as technology companies will admit – are not yet nearly accurate enough to operate across the breadth and depth of the internet. There are more than a billion uploads to Facebook each day and 300 hours of video uploaded to YouTube each minute of the day.

This means that any machine-learning based solution will have to be paired with a significant team of human analysts that can resolve complex and often subtle issues of intent and meaning that are still out of reach of even the most sophisticated machine learning solutions. more> https://goo.gl/X2ACdL

The Coming Software Apocalypse

By James Somers – “When we had electromechanical systems, we used to be able to test them exhaustively,” says Nancy Leveson, a professor of aeronautics and astronautics at the Massachusetts Institute of Technology who has been studying software safety for 35 years. She became known for her report on the Therac-25, a radiation-therapy machine that killed six patients because of a software error. “We used to be able to think through all the things it could do, all the states it could get into.

Software is different. Just by editing the text in a file somewhere, the same hunk of silicon can become an autopilot or an inventory-control system. This flexibility is software’s miracle, and its curse. Because it can be changed cheaply, software is constantly changed; and because it’s unmoored from anything physical—a program that is a thousand times more complex than another takes up the same actual space—it tends to grow without bound. “The problem,” Leveson wrote in a book, “is that we are attempting to build systems that are beyond our ability to intellectually manage.” more> https://goo.gl/XSu4jU

5 Mindsets to Bring Positive Change Across Society

By Raya Bidshahri – To contribute to human progress, it is not enough to be intelligent, resourceful, or well-connected. Those are all factors that play a significant role but aren’t the true driving forces of disruptive innovation. Stimulating positive change at civilization level also requires certain mindsets and ways of thinking.

Here are five mindsets that will allow us to leave a positive mark on humanity.

  1. Curiosity and Critical Thinking
    One of the tragedies of our education system is that it fails to nurture the childlike sense of wonder that we are all born with.
  2. Intelligent Optimism
    Nothing productive will come from blind optimism and ignorance of some of the brutal realities of our world.
  3. Risk-taking
    Paving a new way forward for humanity comes at a cost. More often than not, executing a radically disruptive idea is a risk.
  4. Moonshot Thinking
    Instead of looking to make a 10 percent gain or improvement in a current product or idea, moonshot thinking involves aiming for a 10x improvement of the status quo.
  5. Cosmic Perspective
    We’ve all heard of “thinking big” or ‘big-picture thinking.” Moving beyond that involves having a cosmic perspective.

It’s about asking the right questions, being intelligently optimistic about the future, taking a risk with a moonshot, and maintaining a cosmic perspective. more> https://goo.gl/V2bVjb

Optic Zoo Networks Keeps Vancouver’s Data Traveling at Blistering Speeds with Ciena

By Tony Ross – Optic Zoo Networks is a recognized brand throughout metro Vancouver due to our extensive carrier grade dark fiber network and infrastructure. Based on demand and to further accelerate our growth and better serve Tier 1 service providers, we knew it was time to take our offerings to the next level.

Our customers need to support bandwidth-hogging applications like virtual and augmented reality, as well as Internet of Things (IoT). However, in order for data to continue to flow with ease, we needed to ensure that Optic Zoo Networks was ready to support that growth. That meant offering new Carrier Ethernet Services (CES), and in turn, required that we build a Carrier Ethernet Network (CEN).

To continue to support top-echelon service providers, however, we needed to build a CEN that could scale instantaneously and meet the needs of organizations in a range of industries – from finance, healthcare, education, and more.

For example, customers that previously wanted to upgrade to higher levels of bandwidth had to go through inefficient processes, such as having to order a network loop that could take weeks. With our CEN, today’s 1G customers can easily upgrade to 10G tomorrow with a simple software upgrade. more> https://goo.gl/fh54t3

Local communities are driving global politics

By Raghuram G. Rajan – We live in a strange time.

Countries are more prosperous than ever before, new technologies that promise to solve our most intractable problems are on the horizon, and yet there is widespread unhappiness in some of the richest countries in the world. White males of working age in the United States are killing themselves through alcohol, drugs, and suicide at a rate that is as if 10 Vietnam Wars were raging simultaneously.

The immediate reason appears to be economic despair, as moderately educated workers lose jobs because of trade and automation. But workers lose (and gain) jobs regularly.

Why are even well-educated workers, holding decent middle-class jobs, so disheartened now? What should we do?

What we are seeing is a consequence of the information-technology revolution that started in the early 1970s, magnified by trade.

Every past technological revolution has been disruptive, prompted a societal reaction, and eventually resulted in societal change that helped us get the best out of the revolution. We have felt the disruption of the IT revolution, which has sometimes been punctuated by dramatic episodes such as the 2007–10 global financial crisis; we are now seeing the reaction in populist movements of the extreme left and right.

What has not happened yet is the necessary societal change, which is why so many despair of the future.

We are at a critical moment in human history, when wrong choices could derail human economic progress. more> https://goo.gl/aLSuFh

Do We Need to Rethink What College Means?

BOOK REVIEW

Bridging the Gaps. Authors: James Rosenbaum, Caitlin E. Ahearn and Janet E. Rosenbaum.

By Dwyer Gunn – There are two ways to look at America’s college-for-all movement. On the one hand, it represents a rare policy success: Today, 90 percent of high school graduates enroll in college within eight years of graduating from high school, up from 45 percent in 1960.

On the other hand, it serves as a cautionary tale about the unintended consequences of even the best-intentioned policy initiatives.

The book is actually named for them—the three gaps. And the gaps are really quite outrageous. When we interviewed students, the students talked about these three things: taking courses without getting credits, getting credits that didn’t count for credentials, and getting credentials that didn’t have payoffs in the labor market.

We found that such students were making bad choices because they didn’t have good information. And they were losing a lot of time and, ultimately, dropping out with no payoff. more> https://goo.gl/KKfJmS

The Next Crisis Will Start in Silicon Valley

By William Magnuson – It has been 10 years since the last financial crisis, and some have already started to predict that the next one is near. But when it comes, it will likely have its roots in Silicon Valley, not Wall Street.

Our banks are better capitalized than ever. Our regulators conduct regular stress tests of large institutions. And the Dodd-Frank Act imposes strict requirements on systemically important financial institutions.

But while these reforms have managed to reduce the risks that caused the last crisis, they have ignored, and in some cases exacerbated, the emerging risks that may cause the next one.

These financial technology (or “fintech”) markets are populated by small startup companies, the exact opposite of the large, concentrated Wall Street banks that have for so long dominated finance. And they have brought great benefits for investors and consumers. By automating decision-making and reducing the costs of transactions, fintech has greased the wheels of finance, making it faster and more efficient.

But revolutions often end in destruction. And the fintech revolution has created an environment ripe for instability and disruption. It does so in three ways. …

Wall Street is no longer the future of finance. Silicon Valley is. more> https://goo.gl/LK6CsY

Return of the city-state

BOOK REVIEW

Radicals Chasing Utopia, Author: Jamie Bartlett.
The End of the Nation State, Author: Jean-Marie Guéhenno.
The End of the Nation State, Author: Kenichi Ohmae.
The New Localism: How Cities Can Thrive in the Age of Populism, Author: Bruce Katz.

Nation-states came late to history, and there’s plenty of evidence to suggest they won’t make it to the end of the century
By Jamie Bartlett – To the people living under the mighty empire, these events must have been unthinkable. Just as they must have been for those living through the collapse of the Pharaoh’s rule or Christendom or the Ancien Régime.

We are just as deluded that our model of living in ‘countries’ is inevitable and eternal.

Which is all rather odd, since they’re not really that old. Until the mid-19th century, most of the world was a sprawl of empires, unclaimed land, city-states and principalities, which travelers crossed without checks or passports. As industrialization made societies more complex, large centralized bureaucracies grew up to manage them.

Those governments best able to unify their regions, store records, and coordinate action (especially war) grew more powerful vis-à-vis their neighbors. Revolutions – especially in the United States (1776) and France (1789) – helped to create the idea of a commonly defined ‘national interest’, while improved communications unified language, culture and identity. Imperialistic expansion spread the nation-state model worldwide, and by the middle of the 20th century it was the only game in town.

There are now 193 nation-states ruling the world. more> https://goo.gl/2N1bGb
