Boston Lisp Meeting: Monday 2010-09-20 Hari Prashanth on Functional Data Structures for Typed Racket

A Boston Lisp Meeting will take place on Monday, September 20th 2010 at 1800 at NEU WVH 366. Hari Prashanth will speak about Functional Data Structures for Typed Racket.

Additionally, we will have two Lightning Talks. Speakers to be announced.

1 Hari Prashanth on Functional Data Structures for Typed Racket

Scheme provides excellent language support for programming in a functional style, but little in the way of library support. In this talk, I present our experience developing a comprehensive library of functional data structures in Typed Racket a typed variant of Racket, which allows us to maintain the type invariants of the original definitions.

Hari Prashanth is a Master's student at Northeastern University. He is working with Sam Tobin-Hochstadt for his thesis. His advisor is Matthias Felleisen.

2 Lightning Talks

At every meeting, before the main talk, there are two slots for strictly timed 5-minute "Lightning Talks" each 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, September 20th 2010 at 1800 (6pm) at NEU WVH 366.

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 near to Parker St (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.

Many thanks go to Eli Barzilay for arranging for the room, and to Northeastern University for welcoming us.

4 No Dinner

We haven't been able to renew sponsorship from our usual partners for 2010, and are not planning to have after-meeting buffet anymore at this point. An informal group will probably gather to have dinner within walking distance of the venue.

5 More about the Meeting

The previous Boston Lisp Meeting on Monday, July 26th 2010 had about participants. Slava Pestov spoke about Factor: an interactive, dynamic, stack-based programming language.

We're always looking for more speakers. The call for speakers and all the other details are at: Volunteers to give Lightning Talks are also sought.
