Abstract:

Producing industry impacts has been an important, yet challenging task for the research community. Although there are a few cases on reporting 'what to do' (reflecting good things to keep doing and replicate elsewhere), there are still strong needs of reporting successful technology-transfer cases and stories behind them for the research community to learn from and replicate. This talk presents the successful technology-transfer case of Pex (http://research.microsoft.com/projects/pex) and its relatives (tools derived from or associated with Pex) from Microsoft Research and lessons learned from more than eight years of research efforts by the Pex team of Microsoft Research in collaboration with academia. Moles, a tool associated with Pex, was shipped as Fakes with Visual Studio since August 2012, benefiting a huge user base of Visual Studio around the world. The number of download counts of Pex and its lightweight version called Code Digger has reached tens of thousands within one or two years. Pex4Fun (http://www.pex4fun.com/, derived from Pex), an educational gaming website released since June 2010, has achieved high educational impact, reflected by the number of clicks of the 'Ask Pex!' button (indicating the attempts made by users to solve games at Pex4Fun) as over 1.4 million till now. Very recently, Code Hunt (https://www.codehunt.com/) was released by Microsoft Research for adding more fun and gaming effects as an extension to Pex4Fun.
