Programming language support to ensure that programs correctly enforce their security policies would help, but, to date, no language has the ability to verify the enforcement of the kinds of policies used in practice---dynamic, stateful policies which address a broad range of concerns including forms http://www.digwin.com/roles-stacks-histories-a-triple-for-hoare Behavioural type and effect systems regulate properties such as adherence to object and communication protocols, dynamic security policies, avoidance of race conditions, and many others. Typically, each system is based on some specific syntax of constraints, and is checked with an ad hoc solver. Instead, we advocate types refined with first-order http://www.digwin.com/nasa-and-microsoft-ask-citizen-scientists-to-be-a-martian Built on Microsoft cloud services technologies, NASA’s interactive “citizen-science” Web service lets anyone explore the Red Planet up close, while also contributing to Mars missions. http://www.digwin.com/games-for-learning-institute-announces-design-contest-for-microsofts-xna-game-studio-pl The Games for Learning Institute, a joint research endeavor of Microsoft Research, New York University, and other universities, has announced the Game Design Challenge to build mini-games for learning on Microsoft’s XNA Game Studio 3.1 platform. http://www.digwin.com/evaluating-recommender-systems Recommender systems are now popular both commercially and in the research community, where many approaches have been suggested for providing recommendations. In many cases a system designer that wishes to employ a recommendation system must choose between a set of candidate approaches. A first step towards selecting an appropriate algorithm is to http://www.digwin.com/action-prediction-and-identification-from-mining-temporal-user-behavior Predicting user's action provides many monetization opportunities to web service providers. If a user's future action can be predicted and identified correctly in time or in advance, we can not only satisfy user's current need, but also facilitate and simplify user's future online activities. Traditional works on user behavior modeling such as http://www.digwin.com/microsoft-chief-research-and-strategy-officer-craig-mundie-shared-vision-for-future-of-com Craig Mundie, chief research and strategy officer of Microsoft delivered a lecture titled Rethinking Computing at The Chinese University of Hong Kong on Nov. 16. http://www.digwin.com/the-use-of-assertions A new study from Microsoft Research shows the power of seeding your code with assertions. http://www.digwin.com/bendable-magnetic-interface A sensing surface developed by Microsoft researchers offers new ways to use computers. http://www.digwin.com/ortc-sample-code We provide sample code implementing the algorithm described in our 1999 paper “Optimal Compression of IP Routing Tables.” This is a single C file: no binary, installation kit, nor documentation. http://www.digwin.com/finding-heapbounds-for-hardware-synthesis Dynamically allocated and manipulated data structures cannot be translated into hardware unless there is an upper bound on the amount of memory the program uses during all executions. This bound can depend on the generic parameters to the program, i.e., program inputs that are instantiated at synthesis time. We propose a constraint based method for http://www.digwin.com/modelbased-testing-of-web-applications-using-nmodel We show how model-based on-the-fly testing can be applied in the context of web applications using the NModel toolkit. The concrete case study is a commercial web-based positioning system called WorkForce Management (WFM) which interacts with a number of other services, such as billing and positioning, through a mobile operator.
