Kate took this exclusive spy photo of the T's newest Red Line car in Harvard Square at Honk at Oktoberfest yesterday (photo used under Creative Commons).

David Kruta was also there. As were 16WadeSt, RedGoldFly, BehindDarkEyes, 1130am, Oakenguy, Connie and Asphaltstadt.

Redgoldfly spies some clothes outside Oona's in Harvard Square.

Sam Baltrusis has the scoop on the Harvard Square landmark/joint, shut on Sept. 20 by a grease fire.

David Harris files a video report from Harvard Square: Protesters protest bailout, foreclosures and Jeff Jacoby.

Bookdwarf has the scoop.

The new owners are Jeff Mayersohn and his wife, Linda Seamonson:

Mayersohn, who lives in Wellesley, said, "As a customer of Harvard Book Store for over thirty years, I'm overwhelmed and elated by this opportunity. My wife and I have wanted to own a bookstore for many years--I never imagined that it could be Harvard Book Store."

Mayersohn is a vice president at Sonus Networks, which builds equipment for heavy-duty Voice over IP networks - he's an alumnus of BBN and GTE Internetworking. Sonus has had some issues this year.

She suffered an ankle injury and cuts in the early Sunday incident at Mass. Ave. and Everett Street, but the bus and the students aboard it came out OK, the Crimson reports.

The Crimson reports on a spate of robberies at Harvard dorms and attacks on Harvard students in Harvard Square:

For a few Quincy House residents, their suite offered small comfort from the rain this weekend as they awoke Saturday to the sound of a male intruder robbing their room. The thief was stealing what amounted to be the third laptop that was snatched from Quincy students in the past week. ...

Three physicists claim that shutting certain Boston roads at rush hour could actually improve traffic flow. Unfortunately, we'll have to wait for the next issue of Physical Review Letters to learn which roads. In the meantime, we have this synopsis from the Economist of the paper by Hyejin Youn and Hawoong Jeong, of the Korea Advanced Institute of Science and Technology, and Michael Gastner, of the Santa Fe Institute, who spent quite a bit of time analyzing traffic flows in Boston, London and New York. Locally, they looked at different ways to get from Harvard Square to Boston Common:

... Modifying the road network could reduce delays. And contrary to popular belief, a simple way to do that might be to close certain roads. This is known as Braess's paradox, after another mathematician, Dietrich Braess, who found that adding extra capacity to a network can sometimes reduce its overall efficiency.

In Boston the group looked to see if the paradox could be created by closing any of the 246 links. In 240 cases their analysis showed that a closure increased traffic problems. But closing any one of the remaining six streets reduced the [total commute time] of the new Nash equilibrium.

Cambridge Police were kept busy this weekend responding to a series of reports of angry people who didn't feel like keeping things bottled up:

Friday:

• A black woman shoved into a fare gate at Alewife by an angry white man, between 50 and 60, screaming racial epithets at her.
• A Sidney Street resident scratched and smacked in the face by his angry ex-girlfriend from Allston.

Grease fire in the hood over the grill at Mr. Bartley's shuts both it and the Hong Kong, the Crimson reports.
