The iconic MIT home page Spotlight features a daily-changing image and design that focuses on advances in research, technology and education taking place at the Institute. Though some Spotlights do run multiple days - for example Friday's spot usually runs through the weekend, we work very hard to maintain the daily-changing tradition. We've combed our servers and have compiled a digital archive of the Institute home page through the years - well over 2000 images. Enjoy!

In computer-science classes, homework assignments consist of writing programs. It’s easy to create automated tests that determine whether a given program function yields the right outputs to a series of inputs, but those tests say little about whether the function is efficiently designed or whether it contains catastrophic errors that the test inputs happen not to elicit. Professors and teaching assistants review students’ code to try to flag obvious mistakes, but even in undergraduate lecture courses, they usually don’t have time for exhaustive analysis.

In April, MIT researchers will present a new system that automatically compares students’ solutions to programming assignments, lumping together those that use substantially similar techniques.

The MIT home page Spotlight showcases the research, technology and education advances taking place at the Institute every day.

What makes it as a Spotlight image is an editorial decision by the MIT News Office based on factors that include timeliness, promotion of MIT's mission, the balance of interest to both internal and external audiences, and appropriateness.

We do welcome ideas and submissions for spotlights from community members, but please note we are not able to accommodate all requests. We are unable to run event previews or promotions as spotlights; for those looking to promote an event, we are happy to include your listing as an event headline on the homepage (when space is available). For more information, e-mail the spotlight team.

Today’s Spotlight features a photograph, taken by Petty Officer 3rd Class Geoffrey Lewis of the U.S. Navy/Department of Defense, that shows the USS Mobile Bay leading the USS Curtis and USS Russell in a composite training unit exercise.

The ongoing turmoil in Iraq has prompted calls for a renewal of U.S. military action in that country, as well as criticism from those who want to avoid further military commitment there.

Among the dissenters: Barry Posen, an MIT political scientist who has become an increasingly vocal critic of what he sees as excessive hawkishness in U.S. foreign policy. Posen believes that U.S. long-term strategy relies too heavily on a bipartisan commitment to military activism in order to pursue the goal of spreading liberal democracy — what he calls the “liberal hegemony project” that dominates Washington.
