Data crunching has grown so sophisticated and powerful, privacy researchers now warn that tracing identities from a pool of supposedly "anonymized" data is not just a possibility, it's a certainty.

"It is depressingly hard to try to anonymize data in a way that resists identification by a committed adversary," Arvind Narayanan, a privacy researcher at Princeton University, told NBC News.

such as the DuckDuckGo search engine, whose motto is "We don't track you" — gain popularity, an incentive would arise.

In the group that did the best someone took on a lead role and was able to delegate and make sure things were done effectively. This makes me wonder about teaching project management and group dynamics for the social sciences and other solo-author disciplines?

The expression "Big Brother" has become dated. Experts would seem to have reached consensus on the term "Big Data" to describe the new favorite topic of discussion in boardrooms, at conventions like Berlin's re:publica last week, and in a number of new books. Big Data promises both total control and the logical management of our future in all aspects of life.

New is the way companies, government agencies and scientists are now beginning to interpret and analyze their data resources. Because storage space costs almost nothing nowadays, computers, which are getting faster and faster, can link and correlate a wide variety of data around the clock. Algorithms are what create order from this chaos. They dig through, discovering previously unknown patterns and promptly revealing new relationships, insights and business models. Though the term Big Data means very little to most people, the power of algorithms is already everywhere. Credit card companies can quickly recognize unusual usage patterns, and hence automatically warn cardholders when large sums are suddenly being charged to their cards in places where they have never been. Energy companies use weather

According to official figures, since the Swedish capital Stockholm began using algorithms to manage traffic, drive times through the city's downtown area have been cut in half and emissions reduced by 10 percent. Online merchants have recently started using the analyses to optimize their selling strategies. The widespread phrase "Customers who bought this item also bought …" is only one example of the approach.

use and share open educational materials, which are basically defined as free resources created on a license that allows users to share, revise, and repurpose them as they see fit.

BMW and Toyota have collaborated in the area of sharing costs and knowledge for electric car battery research, despite the fact that both compete in the luxury car segment. In fact, they have a history of collaborating with each other.

Bill and Melinda Gates Foundation funded a collaborative research consortium comprised of investigators around the world in order to speed up HIV vaccine development.

Be clear about what you are collaborating on. Set boundaries for collaboration at the beginning.Have a limited and well-defined purpose for the collaboration.Be clear about use and ownership of existing and jointly-created intellectual property.Depending on the situation, you may need to involve legal counsel. Collaborating with other firms, even competitors, may be what is needed to help both parties advance and improve. Be open to the possibilities, yet clear about the boundaries.

In Axonify’s platform, assessment and training are directly tied together. Because many employees use Axonify regularly, the platform is able to constantly track employee knowledge and intelligently provide the information needed to close an employee’s individual knowledge gap, says Leaman. The app also leverages learning research to optimize retention by repeating the questions in specific time intervals. Even after an employee “graduates” out of a specific topic, the questions will still be revisited about seven months later to help lock in the knowledge.

Tin Can, on the other hand allows companies and employees to record more common learning events: attending a session at a conference, say, or researching and writing a company blog post. “Companies are starting to recognize how employees actually learn and allowing them to do it the way they wish to, rather than forcing them into a draconian system,” Martin says.
