Last month, British Prime Minister David Cameron paid a visit to the MIT Media Lab as a part of his weeklong tour of the U.S. to promote the United Kingdom with Prince Harry. Cameron was welcomed by Media Lab director Joichi Ito and MIT president L. Rafael Reif. Policemen stood guard outside the Media Lab throughout Cameron’s visit, with at least one sniper on the roof of Senior House.

It’s been a little more than a year since edX, the nonprofit online learning enterprise founded by MIT and Harvard, first launched with much fanfare and a lot of press. Now, the enterprise encompasses 27 schools from 11 countries. In the past two weeks alone, edX has added more than half of those schools. At the same time, edX has completely overhauled its website design with the intentions of making it more colorful, sleek, and ultimately more appealing to the world. Finally, last Saturday, edX released its entire source code with the hopes of making the learning platform an open source project to which the community can contribute.

Last Tuesday, Dean for Student Life Chris Colombo announced that Bexley Hall would be closed for up to three years for renovations, displacing all residents at the end of this semester. On Friday, the Bexley community collectively voiced their concerns and wishes in a letter addressed to Chancellor Eric Grimson PhD ’80 and Dean Colombo, signed by over 70 students and GRTs. Grimson and Colombo responded to the letter yesterday afternoon. In the meantime, Bexley residents were given the option of entering a housing lottery, which closed yesterday at 5 p.m., if they wanted to remain in on-campus housing next year.

On Wednesday, Salman A. Khan ’98, founder of Khan Academy, was brought to MIT by StartLabs to speak about starting Khan Academy and what he’s doing now. He fielded questions from MIT President Rafael Reif, who interviewed him on the stage of Kresge Auditorium.

In early spring, the Association of Student Activities (ASA) emailed to all ASA-recognized student groups requiring that the information in their ASA database entry to be up-to-date and compliant with the ASA’s rules and regulations. One of the requirements was that group constitutions include the ASA Governance Clause ­— any group missing the clause from its constitution received a notification of such, requiring that the clause be added in order for the ASA to approve the constitution. (The Tech, as it is currently an ASA-recognized group without the governance clause, also received this request.) The clause as a requirement for ASA-recognized groups has existed for several years, according to ASA president Rachel H. Keeler ’14, but has not been uniformly enforced.

Next time you have something to say about the dining halls, consider talking to the members of MIT’s House Dining Committee (HDC).

Last semester, the freshman class’ passing rate for the math and science General Institute Requirements (GIRs) was 96.3 percent. According to Julie B. Norman, the Senior Associate Dean for Undergraduate Education, this pass rate is similar to previous years’ numbers.

What does the co-creator of Lost and director of the next Star Wars film have to do with an international chess grandmaster? A successful fashion designer? The author of a New York Times bestseller?

This year, 25.9 percent of freshmen were offered early sophomore standing, down slightly from last year’s 26.9 percent. Of the 296 eligible, 134 freshmen have accepted so far. Offers were sent out in late November by the Senior Associate Dean for Undergraduate Education Julie B. Norman. Although freshmen have until Add Date, March 8, to accept, Norman does not expect the number to rise significantly.
