Ferguson: America’s cultural segregation fault lines


BOOK REVIEW

Habits of the Heart (pdf), Author: Robert Bellah.

The Big Sort: Why the Clustering of Like-Minded America Is Tearing Us Apart, Authors: Bill Bishop and Robert Cushing.

By Neal Gabler – We don’t live in America anymore. We live in thousands of Americas, many no farther away than our computer screens and the Internet. These are self-identified Americas.

But there is another, more pernicious effect of cultural segregation. It shrinks the world rather than enlarges it — reinforces what already is, circumscribes people within their own worldview.

In a segregated world, especially the virtually segregated world we now have thanks to the Internet, we need never leave our own cultural ghetto. more> http://tinyurl.com/kewk6pl

Why An Anti To-Do List Might Be The Secret To Productivity


By Joel Gascoigne – My approach with the Anti-To-Do List is to have not just a single list each day, as many of us do now (our to-do list), but to have two.

The idea of the Anti-To-Do List is that it is the account of progress for that day. In some ways it’s a “Done” List.

This is really powerful, because you can always look back at your Anti-To-Do List and see how much you’ve got done (even if the items weren’t on your todo list). more> http://tinyurl.com/llr3ag8

How Watson Changed IBM


By Brad Power – IBM, a company with a long and successful tradition of internally-focused R&D activities, is adapting to this new world of creating platforms and enabling open innovation.

So how does it work?

With multiple business models. Mike Rhodin, IBM’s senior vice president responsible for Watson, told me, “There are three core business models that we will run in parallel.

The first is around industries that we think will go through a big change in “cognitive” [natural language] computing, such as financial services and healthcare.

The second is where we see similar patterns across industries, such as how people discover and engage with organizations and how organizations make different kinds of decisions.

The third business model is creating an ecosystem of entrepreneurs. We’re always looking for companies with brilliant ideas that we can partner with or acquire. more> http://tinyurl.com/lp6cnqp

Will Your Next Hard Drive Be Liquid?


By Cabe Atwell – Two material scientists, Sharon Glotzer and David Pine, are on a mission to create the world’s first liquid hard drive. Their current calculations estimate that one teaspoon of this liquid data would be able to store 1 TB of data.

This research is building on the work of other researchers to find denser ways to store data. Harvard researchers have recently stored 700 TB on a single strand of DNA, so DNA still takes the cake when it comes to natural data-storing ability.

However, it may not become a USB stick anytime soon. more> http://tinyurl.com/qf7kzso

From CEO ‘Takers’ To CEO ‘Makers’


By Steve Denning – The rotten foundations of shareholder value theory in the writings of Friedman and Jensen are now lost to the public view.

Business schools in particular have a responsibility to stop teaching shareholder value in their core curriculum to their students and start systematically teaching the better idea: the primary purpose of the corporation is to serve customers’ interests.

Business schools must recognize that it is not enough to teach Customer Capitalism as an optional subject. Textbooks that teach shareholder value theory as a basic assumption must be discarded. more> http://tinyurl.com/pe3bvbb

The Intricate Puzzle Known as Chip Design


By Bob Smith – These days, chip design may seem like an intricately connected jigsaw puzzle, including small, oddly shaped interlocking pieces.

Instead of static parts of a puzzle – typically, 300, 500, 750 or 1,000 pieces – spread across a coffee table, a chip under design has loads of dynamic parts located in a variety of directories or sub-directories found on various computers.

The focal point is the processor, not the center of a well-known and photographed painting or skyline, as is often the case with puzzles.

Ah, but memories are playing almost as big a role as processors, especially in chips slated for mobile multimedia devices with higher bandwidth and performance, and low-cost and power requirements.

Fortunately, things aren’t that dire any longer for engineers worried about a chip’s system yield and reliability. One clever engineering group was motivated to figure this out. It set a goal to implement a DDR memory subsystem that would deliver the highest performance and quality within a small footprint and minimal power consumption. more> http://tinyurl.com/k4evteq

Testing Electric Propulsion

NASA – On Aug. 19, National Aviation Day, a lot of people are reflecting on how far aviation has come in the last century. Could this be the future – a plane with many electric motors that can hover like a helicopter and fly like a plane, and that could revolutionize air travel?

Engineers at NASA’s Langley Research Center in Hampton, Va., are studying the concept with models such as the unmanned aerial system GL-10 Greased Lightning. The GL-10, which has a 10-foot wingspan, recently flew successfully while tethered. Free-flight tests are planned in the fall of 2014.

This research has helped lead to NASA Aeronautics Research Mission Directorate efforts to better understand the potential of electric propulsion across all types, sizes and missions for aviation.
