If you’re at the epicentre of South African technological development and entrepreneurship, then you probably already know about JoziHub.  If you don’t, but aspire to moving and shaking with the local shapers of tech innovation, then you’d better brush up on your knowledge quickly.  JoziHub could very well be the new Nirvana for geek innovators.

JoziHub, a sparse yet casual space nestled amongst the cafes and shops at 44 Stanley Avenue in Milpark, Johannesburg, might belie its cutting-edge function at first glance.  This hub of technology exists through the collaborative effort of big tech players; it is spearheaded by Praekelt Foundation and backed by the likes of Omidyar Network, Google, ISlabs and Venture Solutions.

Cathleen Kaveny, John P. Murphy Foundation Professor of Law and Professor of Theology at the University of Notre Dame, talks about how in the broad Christian tradition, believers can act as positive disruptors when they challenge themselves and their communities to uphold the dignity of each and every person.

Kaveny is the author of Law's Virtues (2012)

Positive disruptions: 

Disrupt investments to empower women

Melinda Gates speaks at TEDxChange 2012

TEDxChange, happening this Wednesday, April 3, is a global conversation on some of the most pressing and intractable health and equity issues in our world today — like access to clean water, to schools, to medicine, to technology and to information. Overall, the event will deliver inspiration to those who have the courage to believe that change is possible.

The event, hosted by Melinda Gates, will begin at 9 am (PDT) at the Gates Foundation Campus in Seattle, Washington. The 90 minute program will stream live online at TED.com and TEDxChange.org.

Why should you be one of the many people watching TEDxChange live?

The theme: Positive Disruption. We all want our world to be a better place to live in. But most of us know that sometimes that’s easier said than done. Sometimes, it takes a shake-up to our assumptions, our traditions, our schedules, our values and our communities to get us to spring to action and make real change happen. This is where TEDxChange comes in. It’s that (positive) disruption to your regularly-scheduled program. RSVP to watch »
