Update profile picture from an OpenSocial App

This week we released the possibility to change the current VIEWER’s profile picture from within any OpenSocial app through the OpenSocial JavaScript API:

var person = opensocial.newPerson({thumbnailUrl : 'BASE64_ENCODED_PHOTO'});
opensocial.requestUpdateViewer(person, function(response) {
   // response is either true or false 
});

When the requestUpdateViewer method is called we will ask the user if he really wants to change his profile picture to the new one. The user’s decision will be passed as a parameter to the callback function. As a developer you have to pass the new picture in the thumbnailUrl field of the opensocial.Person object. The content of this field is just the base64 encoded image in a valid Data-URL format.

Mashing up JavaScript – Advanced Techniques for modern Web Apps

Bastian Hofmann,VZnet Netzwerke Ltd.

2011-05-31 | 02:15 PM – 03:15 PM

Nowadays many modern web applications are solely relying on JavaScript to render their frontend. But if you want to create mashups, load data from many different places or include external widgets into your site, you are quickly running into boundaries because of browser and security restrictions. In this presentation I will talk about techniques helping you with such problems.

VZnet at Confoo Conference

VZnet is taking part at this year’s Confoo Conference in Montreal, Canada (March 9th – March 11th) with the following two talks:

Distributed Identities with OpenID

English session
The era of many separated logins and identities in the web is slowly coming to an end. Currently many of the big players are spurring this on with their own proprietary solutions, but open standards are starting to get more support as well with OpenID being the most promising one. In this session I will show how OpenID works for users and developers, where it currently fails and how OpenID is planned to evolve in the future.
Speaker: Bastian Hofmann

How to create social apps for millions of users

English session
Social apps have become very popular in the last years. In this session I will show you how to create an OpenSocial app which can be used by over 900 million users on many social networks around the world. After introducing you to the main concepts behind OpenSocial I will demonstrate live that it is easier than you think to develop a rich social app. Additionally to the basics like accessing the user’s social graph or integration with external APIs, I will also highlight features that will help you with a quick viral distribution, tight integration into the user’s social experience and access through mobile devices.
Speaker: Bastian Hofmann
