This is the announcement letter from Ivan:

Hello everyone,

For our February meeting Johan Tibell kindly agreed to make a talk about high performance Haskell.

The meeting place is our usual place in SoMa, kindly provided by Engine Yard:
500 Third Street, Suite 510 San Francisco, CA 94107
Contact phone (mine): [masked].  Host's phone (Larry's): [masked].
Please arrive a little bit earlier, so that we could start at 7pm sharp.

We may try to set up the video feed through Google Hangout (I will post a public link in my G+ before the meeting starts if we succeed in setting it up), however please don't rely on it and try to visit the meeting in person if possible. If you are going to be joining the hangout, please mute your microphone before you join.

Some people will be going from the South Bay (and probably East Bay) to the meeting and back, so there's a possibility of carpooling. Also, it's very easy to get to Engine Yard from the Caltrain station (4th & King Str) and Embarcadero/Powell BART stations. Please send me a message if you need help figuring out transportation. If you are driving and can take some people from East/South Bay to the meeting and back, please send a message to the[masked] mailing list.
Please retweet/post to reddit/forward this email to those who may be interested in attending. If you plan to attend and you're not yet subscribed, please subscribe to BAHaskell Google Group to follow all the discussions related to this meeting (if you have troubles with the captcha while joining, please send me a direct email).
Cheers, Ivan
