Boston Lisp Meeting: Monday 2009-12-14 Sam Tobin-Hochstadt

A Boston Lisp Meeting will take place on Monday, December 14th 2009 at 1800 at NEU WVH 366. Sam Tobin-Hochstadt will talk about Typed Scheme.

Additionally, we will have two 5-minute Lightning Talks, each followed by 2-minute Q&A. Speakers to be announced.

Also, there will be a buffet offered by ITA Software. Registration is not necessary but appreciated. See details below.

1 Sam Tobin-Hochstadt on Typed Scheme

Typed Scheme is a system for incrementally porting untyped PLT Scheme programs to a typed language. The type system is designed to automatically accommodate typical Scheme idioms, and includes several novel features to support this. It also offers sound and automatic interoperability with untyped code. It has been used in real applications and on thousands of lines of existing Scheme code.

Sam Tobin-Hochstadt is a postdoc at Northeastern University, working for Matthias Felleisen. He is investigating the integration of typed and untyped languages, with a focus on Scheme and JavaScript. As a graduate student, he developed Typed Scheme, which he continues to maintain. He is currently supported by a grant from the Mozilla Corporation.

2 Lightning Talks

At every meeting, before the main talk, there are two slots for strictly timed 5-minute "Lightning Talks" followed by 2 minutes for questions and answers.

The slots for next meeting are still open. Step up and come talk about your pet project! Contact me at fare at

3 Time and Location

The Lisp Meeting will take place on Monday December 14th 2009 at 1800 (6pm) at NEU WVH 366.

Note that we're back on a Monday, and that we're using a new location.

This is at Northeastern University, in the Computer Science building WVH (West Village H, see this picture) when you arrive from the T on Huntington Avenue (Green E line, stop at Northeastern Station, or possibly Museum of Fine Arts; you can also walk from Ruggles on the Orange line). As the number indicates, the room is on the third floor. Northeastern maps and direction: Many thanks go to Eli Barzilay for arranging for the room, and to Northeastern University for welcoming us.

4 Dinner

ITA Software a fine employer of Lisp hackers (disclaimer: I work there), is kindly purchasing a buffet to accompany our monthly Boston Lisp meeting. Anyone who attends is welcome to partake.

We appreciate it if you let us know you're coming, and what food taboos you have, so that we can order the correct amount and kind of food. Tell us by sending email to boston-lisp-meeting-register at We won't send any acknowledgement unless requested; importantly, we'll keep your identity and address confidential and won't communicate any such information to anyone, not even to our sponsors.
