Computing Pioneer Ray Ozzie and Security Veteran Nico Sell Join Code/Mobile Lineup

The term “legend” gets thrown around a lot, but with Ray Ozzie, it is definitely appropriate.

Ozzie worked at Software Arts–the firm that created Visicalc–before leaving to join Lotus, where he created Lotus Notes. From there Ozzie built Groove and, after selling that company to Microsoft, served as Bill Gates successor as chief software architect. For the last couple of years, he has been quietly leading a small team to create Talko, a new kind of collaboration software designed specifically for mobile workers.

Given both his long career and his current focus on mobile, there will be lots to talk about when Ozzie takes the stage at our Code/Mobile event, which takes place Oct. 27-28 in Half Moon Bay, Calif.

Also speaking at Code/Mobile will be Nico Sell, the longtime Defcon organizer and chief executive of encrypted messaging service Wickr. With all the focus around security (and the lack thereof), Sell will offer a unique take on what the Instagrams and Snapchats of the world should be doing to protect their users.

And, if you are wondering about those glasses Sell is wearing in the photo, you can expect to see those, too. Sell wears them in public to keep her retinas private. She takes privacy just as seriously with Wickr, which is designed as a “zero knowledge” system in which the company knows neither the identities of its users nor the contents of their messages.

They join an already stellar lineup as Re/code looks to put the mobile revolution in context.

Also taking the stage will be T-Mobile CEO John Legere, YouTube chief Susan Wojcicki, Motorola president Rick Osterloh along with the founders of Instagram and WhatsApp and many, many more.

Tickets are going fast, so if you want to be in the audience, now is the time to register.
