    Testing Tools at a Conference Week in Zurich


    The beautiful interior of the Eidgenössische Technische Hochschule’s (ETH, the Swiss Federal Institute of Technology) main building in Zurich is always abuzz with conferences at the end of June, including TOOLS—and this year was no exception. Now in its forty-ninth iteration, TOOLS was a week-long event that brought together four major conferences, eight workshops, and a tutorial on the subject of programming languages, models, components, and proofs.

    ETH is a world-famous institute for science and technology; it has produced 21 Nobel Prize winners since its inception in 1855—with seven since 1975—a top score among European universities. Perhaps ETH is more widely known as the place where Albert Einstein began his studies. The chair of Software Engineering is held by Bertrand Meyer, who started the TOOLS Conference Series in 1989 with conferences held in different continents: TOOLS Europe, TOOLS USA, TOOLS Pacific, and TOOLS China.  Eight people from Microsoft were right at the center of the event this year.

    With program committees spread across the world, holding a program committee meeting to discuss the selection of the papers for the conference is a challenge—but one that TOOLS has always met. This year, I had the honor of serving as program co-chair of one of the conferences, and Ethan Jackson was program co-chair of another. The collected papers from TOOLS are available as a volume entitled Objects, Components, Models, Patterns in the prestigious Lecture Notes in Computer Science series, published by Springer.

    The program committee meeting for 2011 was held in Zurich in March with 16 members present and 16 listening in from various regions ranging from India to the United States’ west coast. With very careful planning, papers were scheduled for discussion according to the time zone in their reviewers’ regions. Thus, Aditya Nori from Microsoft Research India was brought in first, and Nikolai Tillmann from Microsoft Research Redmond, Washington, had to rise very early to discuss his papers at the end of the meeting.

    Other Microsoft researchers who participated in the conference week included Yuri Gurevich, the conference co-chair of TAP (Tests and Proofs), and program committee members of the various conferences: Nikolaj Bjorner, Clemens Syzperski, Margus Veanes, and Madhu Sudan. (I should note that Nikolaj Bjorner and his team are well known for having popularized the use of testers through RiSE4fun, which enables the tools to be run in browsers.)

    Patrice Godefroid presented the keynote address for one of the conferences: TAP 2011. He discussed his work with the SAGE tool for white-box testing technology. Test generation has recently become the largest application of SMT solvers as measured by computational usage. Satisfiability Modulo Theories (SMT) are concerned with checking the satisfiability of logical formulas over one or more theories. At Microsoft, the Z3 SMT solver has solved more than 2 billion constraints in the past two years as a sub-component of SAGE, the first white-box fuzzer. Fuzz testing is an effective technique for finding security vulnerabilities in software. Traditionally, fuzz-testing tools apply random mutations to well-formed inputs of a program and test the resulting values.

    Since 2009, SAGE has been running non-stop on more than 100 (on average) machines, automatically “fuzzing” hundreds of applications in a dedicated lab that is owned by the Windows security test team. In the process, SAGE found many new expensive security vulnerabilities (which were missed by black box testing and static program analysis).

    Making the World a Better Place, One Fellow at a Time


    If you wanted to be certain that the best IT minds were focused on research into some of today’s most challenging societal problems, what would you do? How would you ensure that there is a global pipeline of computer-science talent? If you’re Microsoft Research, you would set aside US$1.4 million a year to fund the Microsoft Research Faculty Fellowship program.

    The 2011 Faculty Fellows receive their awards at the Microsoft Research Faculty Summit.

    Now in its seventh year, this program has named 40 academic researchers whose exceptional talent for research and thought leadership make them stand out in their fields. Each Fellow receives up to US$200,000 to pursue breakthrough, high-impact research. The grant is an unrestricted gift, providing the Fellows the freedom to plan their research, hire graduate students, build labs, and acquire equipment. In addition to the monetary grant, each Fellow also receives software, invitations to academic and professional conferences, and the opportunity to work directly with leading computer scientists at Microsoft Research.

    During the 2011 Microsoft Research Faculty Summit, currently in progress in Redmond, Washington (July 18 to 20), we were delighted to announce the recipients of the 2011 Microsoft Research Faculty Fellowships. These stellar researchers were chosen through a rigorous, multi-tier selection process that involved more than 100 expert reviewers. The reviewers looked for future academic leaders who are at the beginning of their careers. Microsoft’s goal is to encourage these early-career faculty and help them work on the kind of high-risk/high-reward research that often is overlooked by traditional funding mechanisms.

    With these goals in mind, the selection criteria included not only the capability to pursue cutting-edge research, but also the personal leadership skills that are necessary to bring those ideas to fruition and to communicate complex concepts in a way that inspires and intrigues. The review process winnowed the list of candidates down to 18 finalists, who were then interviewed in person by a panel of Microsoft Research executives and researchers, along with faculty members from some of the nation’s leading universities.

    Out of this arduous process emerged eight of the best and brightest young researchers—men and women who not only have interesting research agendas, but who also have demonstrated the potential to do great work throughout their careers. So, without further ado, here are this year’s Microsoft Research Faculty Fellows:

    • Maria Florina Balcan, assistant professor, Georgia Institute of Technology, for research in machine learning, adaptation, and intelligence
    • Krishnendu Chatterjee, assistant professor, IST Austria, for research in software engineering
    • Jure Leskovec, assistant professor at Stanford University, for research in data mining, web science, and social computing
    • Alistair McEwan, lecturer, University of Sydney, for research in biomedical engineering
    • Shwetak Patel, assistant professor, University of Washington, for research in human-computer interactions, embedded systems, energy, and sensor networks
    • Anderson de Rezende Rocha, assistant professor, University of Campinas, for research in machine intelligence and pattern analysis
    • Keith Noah Snavely, assistant professor, Cornell University, for research on computer vision
    • Brent Waters, assistant professor, University of Texas, for research on security and cryptography

    So, how do the newest Faculty Fellows feel about their selection? The following are responses from two of them.

    Shwetak Patel, an assistant professor at the University of Washington (departments of Computer Science & Engineering and Electrical Engineering), conducts research in a variety of areas such as energy monitoring technology for the home and health-monitoring technologies that use mobile phones and a sensing system, and has been collaborating with Microsoft Research on natural user interface technologies.

    Reflecting on the Faculty Fellowship, Professor Patel observed that “The biggest benefit of the fellowship is not just the award, but the exposure of my work to the rest of MSR [Microsoft Research] and the MSR connections that come from it. In addition, my students are going to equally benefit from working with MSR through these joint projects.

    “This is a great honor and it is very respected by the community. The MSR Faculty Fellowship is probably one the most prestigious junior faculty awards out there and certainly the most prestigious corporate faculty fellowship.”

    Anderson Rocha, an assistant professor at the University of Campinas (Institute of Computing), is working on new machine-learning and computer-vision techniques to help solve problems that are related to digital document forensics.

    Professor Rocha proudly noted that his selection breaks new ground. “As far [as] I was told, I'm the first Latin American researcher actually working in Latin America to get this award. Therefore, it means a milestone in the sense it can motivate other young researchers in this region to keep working and believing they are also capable of achieving international recognition for their work.

    “The award is an extra motivation for me and my students to keep pursuing digital forensics and innovative techniques to investigate solutions for helping law enforcement agencies in Brazil and abroad in their daily fight against organized crime.”

    Professors Patel and Rocha exemplify the drive and intellect of all eight of our new Faculty Fellows. We are proud to welcome them into the fold, and we look forward to helping them advance computer science’s contributions to the future of society and our planet.

    Bringing the Cloud to a Smartphone Near You


    Bringing the Cloud to a Smartphone Near YouOne of the coolest things about working in Microsoft Research is the opportunity to see what bright students can do with cutting-edge technology. Project Hawaii is a perfect example. This project, which began in January 2010, offers students the opportunity to explore how the cloud can enhance our mobile devices, especially the increasingly ubiquitous smartphone. In Project Hawaii, we’ve provided students with tools, services, and equipment for creating their own cloud-enabled mobile applications. The current Project Hawaii platform consists of a Windows Phone 7 smartphone and several cloud services, including Relay, Rendezvous, Optical Character Recognition, Speech to Text, and Windows Azure for computation and data storage.  

    Some 300 students at 21 universities (see the list of schools) participated in the project earlier this year, building approximately 80 cloud-enhanced apps for the Windows Phone 7. Past Project Hawaii apps have ranged from MobiSafe, which alerts drivers when they have entered an area with a high risk of traffic accidents, to ReceiptManager, which provides one convenient location to consolidate and view all the digital receipts that are generated by the user’s mobile payment applications. Then there’s Flagged Down, an app that lets users search for and hail cabs in their vicinity.

    Just imagine a scenario where MobiSafe alerts you—via a hands-free smartphone, of course—that you’re driving into an accident danger zone. You decide to park your car and, by using Flagged Down, you easily hail a nearby taxi, which takes you safely to your destination. You pay the driver with your debit card, and the amount is automatically added to your (unfortunately) growing stack of payments in the ReceiptManager.

    Sound far-fetched? Well, so did GPS and robotic vacuum cleaners not too long ago. Really, there is no limit to the possible applications that these talented, motivated students can conceive.

    Another Project Hawaii application has the potential to save lives by recording a heart patient’s EKG (electrocardiogram) and location and relaying these data to healthcare professionals via a web-based portal. Or maybe you’re a lonely zombie, pining away for another brain-chomping buddy. Fear not: a Project Hawaii game app will enable you to infect other players when they’re in physical proximity to you. Just think of the possibilities for a zombie mob-flash—or more seriously, the options for a variety of location-based games.

    Professor Nilanjan Banerjee, whose programming paradigms class at the University of Arkansas developed the above-mentioned remote EKG monitoring app, exudes a level of enthusiasm that is characteristic of faculty members who are involved in Project Hawaii. “Hawaii is a platform that helps rapid development of fairly complex applications. With the help of cloud services that can be accessed through simple intuitive APIs, the time to developing a sophisticated application is reduced considerably,” he says. “This is especially important in a project-oriented course, where the system needs to be built and adequately tested within a two-three month time frame.”

    “There are two ingredients that the Hawaii initiative provides that are key to the success of a mobile system or programming class,” continues Professor Banerjee. “First, for the instructor, it provides access to functional cloud services (and example source code) that he can use to demo cloud-enabled applications in class. Personally, I have found it very fruitful to demo services like the relay and speech-to-text in class and run my students through the client-side source code. Second, Hawaii provides us access to actual Windows Phones that students can play with—I have found that the interest of students is spiked when they work with real devices.”

    Another of Professor Banerjee’s classes, “Hot Topics in Mobile and Pervasive Computing,” developed Traveltant (shorthand for travel consultant), a Windows Phone 7 application that combines data from Facebook, Bing, and Yelp to provide personalized planning and recommendation to users while traveling.

    Several 2011 Project Hawaii apps will be demonstrated at the Microsoft Research Faculty Summit, which is in progress in Redmond, Washington, from July 18 to 20. One that we expect to generate great interest comes from Stanford University and was developed by a group of students in Professor Jay Borenstein’s Computer Science Innovation class who collaborated with Microsoft Research to create myscience, a platform that enables scientists to launch citizen-science projects instantly. By using this Windows Phone 7 experience, citizens can capture data through sensors on the phone and submit the data to various scientific studies.

    According to Professor Borenstein, “Project Hawaii was a key piece in enabling the sensor data from the phone to reach the Azure cloud in a reliable and efficient manner. In this case, Project Hawaii aided the development of software for creating substantial scientific data sets that would otherwise have been impractical to assemble. The tools made it possible for a team of students to create a full-featured application serving two audiences—scientists and ordinary citizens with Windows phones—in less than five months.”

    Like I said, one of the coolest things about working at Microsoft Research is seeing what creative young people can do with technology. Oh, and the free soda—that’s pretty cool, too.
