Terribly saddened by the Sandy Hook Elementary School shooting. Thoughts and prayers go out to the families of the victims, and hopefully we can all come together and figure out how to never ever let something like this happen again.

Plenty more holiday parties this week. The one event you don't wanna miss is the Queens Tech Meetup Holiday Party. QTM has quickly raced to almost a thousand members, and this Wednesday they've assembled a rockstar panel of women in NYC tech including Rachel Haot (Chief Digital Officer, New York City), Reshma Saujani (Founder, Girls Who Code and former New York City Deputy Public Advocate). Jessica Lawrence (Managing Director, New York Tech Meetup) and Helen Marshall (Queens Borough President and Coalition for Queens). Long Island City is happening, yo!

Who wants high-speed broadband fiber goodness at their business? You do! The NYCEDC may be bringing you the Christmas gift you always wanted. It's called the NYC Fiber Challenge. Winners receive free fiber build-out to their business, an overall value of up to $7 million for all winning businesses over two years. The application deadline is 2pm on December 27. Go get 'em! If you wanna learn more, there'll be a few workshops this week in Long Island City and Brooklyn.

Matter Ventures, a new incubator for media startups supported by The Knight Foundation, KQED, and Public Radio Exchange will be holding an information session on December 18th from 6:30 to 8:30pm at the CUNY Graduate School of Journalism. Inaugural class begins in late February and the deadline for applications is January 6th.

In other news, Manhattan's hottest new museum is ... MoMath! It's the first math museum in the U.S. and, true to its name, math pervades every aspect of the design--even the cafe, where the walls are made of Tetris-like puzzle shapes called pentominoes, and the tables are arranged as a knight would progress on a chessboard. The museum is located at 11 E. 26th St (north of Madison Square Park) and open everyday from 10 to 5. So go check it out and don't forget to take your kids (and nieces and nephews) along. It's about time we made an effort to make math cool and fun!

And if you're looking to check out GPS shoes with LED lights, a high-tech music box, Rotobooths and 3D printers, head on over to the WIRED popup store in SoHo (583 Broadway). It's open 11am-7pm Tuesday to Sunday through December 23rd.
