Sam Tobin-Hochstadt will speak 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. http://www.ccs.neu.edu/home/samth/typed-scheme/ 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!

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 http://tmp.barzilay.org/wvh.jpg 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: http://www.northeastern.edu/campusmap/maps.html 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 common-lisp.net. 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. 5 More about the Meeting The previous Boston Lisp Meeting on Thursday, October 29th 2009 had about 30 participants. Daniel Herring spoke about LibCL and Alex Plotnick about CLWEB. http://fare.livejournal.com/148335.html We're always looking for more speakers. The call for speakers and all the other details are at: http://fare.livejournal.com/120393.html Volunteers to give Lightning Talks are also sought. http://fare.livejournal.com/143723.html For more information, see our web site http://boston-lisp.org/ For posts related to the Boston Lisp meetings in general, follow this link: http:// fare.livejournal.com/tag/boston-lisp-meeting or subscribe to our RSS feed: http://fare.livejournal.com/data/rss?tag=boston-lisp-meeting Please forward this information to people you think would be interested.

Ryan Culpepper will speak about PLT Scheme Macros. 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. 1 Ryan Culpepper on PLT Scheme Macros I will talk about writing macros in PLT Scheme, using the tools I've developed. The first tool is the macro stepper, which shows the macro expansion of programs as a series of rewriting steps. The macro stepper is adapted specifically to the challenges of writing macros in a hygienic macro system using a base language that is itself composed of layers of macros. I'll demonstrate how to use the macro stepper and talk about its implementation. The second tool I'll demonstrate is a specification system for Scheme syntax that makes macros robust and concise. I am a graduate student in the PLT group at Northeastern University working on making macros more powerful and easier to use. I'm interested in exploring new ways of expressing programs and methods of implementing and supporting program expression. 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.
