Boston Lisp Meeting: Thursday 2009-10-29 Alex Plotnick, Daniel Herring http://fare.livejournal.com/147676.html A Boston Lisp Meeting will take place on Thursday, October 29th 2009 at 1800 at MIT 34-401B. Alex Plotnick with talk about CLWEB, and Daniel Herring will give a short presentation of LibCL. 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 Alex Plotnick on CLWEB CLWEB is a literate programming system for Common Lisp in the tradition of Knuth's WEB and CWEB systems. These systems are based on the idea that there are two audiences for every program — the machine on the one hand and human programmers on the other — and that these two audiences have very different requirements for understanding a given program. They take as input a document containing a mixture of source code, TeX, and WEB control codes, and output both a program suitable for compilation or evaluation, and also a TeX file that contains a pretty-printed version of the source code along with accompanying commentary. The former is for the machine, while the latter is ready for typesetting, printing, and reading by a human. CLWEB is of course itself a literate program, written in itself, using (mostly) portable Common Lisp as the source language. http://www.cs.brandeis.edu/~plotnick/clweb/ Alex Plotnick is a graduate student in computer science at Brandeis University. His interests include natural and computer language semantics, computational linguistics, and philosophy of language. 2 Daniel Herring on LibCL LibCL is a self-contained collection of portable, free Common Lisp libraries. LibCL is released on a quarterly cycle and provides the following features. Simple install: download a single file per release. Integration: libraries are tested to work with each other. Community building: aiming for shared licensing and ownership of packages. Platform neutrality: the libraries should be portable across implementations and OSs. Accountability: public read-only git repositories track full history. http://libcl.com/ 3 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 tunes.org. 4 Time and Location The Lisp Meeting will take place on Thursday October 29th 2009 at 1800 (6pm) at MIT 34-401B. Note that this is not the usual day of the week. As the numbers indicate, the room is in Building 34, on the 4th floor. This is the usual location, on 50 Vassar Street, Cambridge.

Boston Lisp Meeting: Wednesday 2009-09-30 Christine Flood http://fare.livejournal.com/147676.html A Boston Lisp Meeting will take place on Wednesday, September 30th 2009 at 1800 at NEU WVG 108, where *Christine* Flood will speak about *Project Fortress*. 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. * *Christine Flood* will speak about *Project Fortress*. Project Fortress is a programming language designed at Sun Labs with these fundamental principles: What you write on your white board works (Standard Mathematical Syntax). Implicit Parallelism (Let the runtime system exploit the fine grained parallelism in your algorithm). Languages should be designed from the ground up to grow over time (A small fixed core with as much of Fortress as possible in Fortress libraries). Other features include strong static typing and transactional memory. This talk will give you an overview of the language and walk through some examples. Feel free to check out our open source implementation and language specification at http://ProjectFortress.sun.com/ Christine Flood is a research scientist at Sun Microsystems Labs. She has been working in the field of computer science for 20 years. Her interests are in programming language design and implementation particularly garbage collection and parallelism. She's a former Symbolics/MIT hacker. * * 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(a)tunes.org for registration. * * * *The Lisp Meeting will take place on Wednesday September 30th 2009 at 1800 (6pm) at NEU WVG 108.* This is neither the usual day of the week, nor the usual location. This is at Northeastern University, in the West Village G residence building which is right behind the Computer Science building WVH (see this picture http://tmp.barzilay.org/wvh.jpg ) 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).

[boston-lisp] lisp house
by Joe Corneli 03 Sep '09

03 Sep '09

[pjb] The walls inside the lisp house are paperthin like in Japanese houses. They're purely symbolic. Some other language may have reinforced concrete interior walls. Choose where you want to live! ;-) [nyef] pjb: Surely that has acoustic as well as thermal implications.... [pjb] Yes, you need to be more civilized in a Japanese house :-) [Xach] chilly during the AI winter -- http://www.cliki.net/IRC%20Quotes Hey, I've been in Boston enjoying myself for one summer, but need a place for fall. I was thinking it would be fun to live with other Lispers. Anyone here interested?

[boston-lisp] Scheme Workshop + Mitch-Wand-fest + BLM Lightning Talks
by Faré 19 Aug '09

19 Aug '09

Dear Boston Lisp Users, I had been repeatedly announcing at our previous meetings that a Scheme Workshop was to take place this year in Boston, but I realize hadn't sent mail about it. The Scheme Workshop 2009 is actually happening this week-end at Northeastern University, followed by a Symposium in honor of Mitch Wand. The official registration deadline is passed since earlier this month, but if you beg the proper person, you might get in. For the Scheme Workshop 2009 this Saturday, see http://users.csc.calpoly.edu/~clements/scheme-workshop-2009/ and contact John Clements <clements(a)brinckerhoff.org> ASAP. For the Mitchfest this Sunday and Monday, see http://www.ccs.neu.edu/events/wand-symposium/ and contact mitchfest-registration(a)ccs.neu.edu ASAP. You might or might not get a lunch, but odds are you can participate still. Since I'm announcing things, I might as well tell you that the two Lightning Talk slots for the August 31st BLM have been filled. Will speak: Gregory Marton about Teaching Linguistics through Programming and Alex Plotnick about Gabriel's Gimmick, an odd little idiom for (mis)using the sequence functions. http://fare.livejournal.com/146665.html However, you are welcome to apply to give a Lightning Talk at one of the later BLMs. While I am at it, you might or might not be interested in the Boston Haskell meeting. The one yesterday was quite interesting. http://groups.google.com/group/bostonhaskell I hope to see some of you soon at one of these events.

Boston Lisp Meeting: Monday 2009-08-31 Emmanuel Schanzer http://fare.livejournal.com/146665.html A Boston Lisp Meeting will take place on Monday, August 31st 2009 at 1800 at MIT 34-401B, where *Emmanuel Schanzer* will speak about *Teaching Mathematics and Problem-Solving through Programming*. Additionally, we are still accepting proposals for up to two volunteers to each give of a 5-minute Lightning Talk (followed by 2-minute Q&A). Also, there will be a buffet offered by ITA Software. Registration is not necessary but appreciated. See details below. * *Emmanuel Schanzer* will speak about *Teaching Mathematics and Problem-Solving through Programming*. Most people agree that students should be exposed to some form of Computer Science before graduating high school, but there is little consensus about what kind of exposure is best. At the same, Algebra has been identified as a pivotally important concept for students, both as the crucial gateway to higher forms of mathematics and as an indicator of future success. This talk explores Bootstrap, a particular approach to computer science education that focuses on Algebra instruction as a natural format for computer programming. Over the course of nine classes, students are exposed to functions and variables, and use their knowledge to design and build a simple videogame. Bootstrap is currently active in middle schools around the country, using volunteer teachers from companies and universities to teach programming to children as young as ten years old. Emmanuel Schanzer is the Program Director for Bootstrap, an organization which trains volunteer teachers to bring functional computer programming to underprivileged middle school students around the country using the curriculum he's developed since 2004. He began teaching Computer Science in 2000, teaching students at Cornell University how to program in Scheme, and later constructed Bootstrap to teach the same concepts as part of an afterschool program. He is now a Doctoral Candidate at Harvard University, studying Cognitive Science and Mathematics Instruction. http://www.bootstrapworld.org/ * * 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! * * * *The Lisp Meeting will take place on Monday August 31st 2009 at 1800 (6pm) at MIT, Room 34-401B.* As the numbers indicate, the room is in Building 34, on the 4th floor.

Boston Lisp Meeting: Monday 2009-07-27 Bruce Lewis, Richard Kreuter http://fare.livejournal.com/145087.html A Boston Lisp Meeting will take place on Monday, July 27th 2009 at 1800 at MIT 34-401B, where Bruce Lewis will speak about OurDoings, and Richard Kreuter will speak about defsystems and deliverables, or, unary REQUIRE for the win! Additionally, we are still accepting proposals for up to two volunteers to each give of a 5-minute Lightning Talk (followed by 2-minute Q&A). Also, there will be a buffet offered by ITA Software. Registration is not necessary but appreciated. See details below. * Bruce Lewis will speak about OurDoings < http://OurDoings.com/ >, a web site that solves the problem faced by people who take a lot of pictures, but don't have much time to share them online. Its approach to the problem is straightforward, but unique. In this talk, Bruce will use the OurDoings web site as context in which to explain how macros enable a kind of abstraction that functions do not, and how this form of abstraction is useful in common problems that thousands of programmers face. Bruce Lewis left the Lisp world after completing MIT 6.001 (Structure and Interpetation of Computer Programs) in Spring, 1987. Ten years later, seeking a better way to write database-driven web applications, he created <a href="http://brl.sourceforge.net/">BRL</a>, the "Beautiful Report Language", an alternative to Perl ("Practical Extraction and Report Language") that dominated web development at the time. Bruce lives in Beverly, Massachusetts with his wife and three children. * * Richard Kreuter will speak about Defsystems and deliverables, or, unary REQUIRE for the win! Common Lisp users have employed a succession of system construction tools ("defsystems") over the years. Howsoever good a defsystem tool might be, overuse of system construction tools creates needless technical and social problems in the community and confounds newcomer and professional alike. This presentation will cover some of the drawbacks of the traditional uses of defsystems, and proposes some approaches to deploying Lisp software intended to make Lisp library usage more tractable than defsystems make it. Richard Kreuter is a software developer in the Boston area. He has worked on Steel Bank Common Lisp, driven himself nuts by too much reading of the Common Lisp standard, and is likely to be the last person on earth who thinks CL's pathnames still are a good idea. * * * Having observed the success of the formula at ILC'2009, we have instituted Lightning Talks at the Boston Lisp Meeting. At every meeting, before the main talk, there are two slots for strictly timed 5-minute talks followed by 2-minute for questions and answers. The slots for next Monday are still open.

Norman Ramsey gave a talk about Using Higher-Order Functions and Continuation-Passing Style to Make Dataflow Optimization Simple. In the near future, we expect to have Bruce Lewis on 2009-07-27 about BRL http://brl.codesimply.net and ourdoings.com, Emmanuel Schanzer on 2009-08-31 about BootstrapWorld.org, and Christine Flood on some undetermined date about Fortress http://projectfortress.sun.com * * * * * * * We're always looking for more speakers.

[boston-lisp] [Final CfPart] 6th European Lisp Workshop, July 6th, Genova, Italy
by Didier Verna 24 Jun '09

24 Jun '09

+------------------------------------------------------------+ | FINAL CALL FOR PARTICIPATION | | 6th European Lisp Workshop | | July 6, Genova, Italy - co-located with ECOOP 2009 | | http://elw.bknr.net/2009 | +------------------------------------------------------------+ Important Dates =============== ECOOP late registration deadline: July 03, 2009 6th European Lisp Workshop: July 06, 2009 Please note that registration must be done with ECOOP itself. There is a reduced registration fee for workshop-only attendance. The early registration deadline is in two days, so register now! See http://ecoop09.disi.unige.it/ for details. 2009 Special News ================= * Edi Weitz will give a keynote address on the use of his notorious open source libraries in commercial / industrial application. * The workshop is sponsored by ITA Software, Inc. Please visit them at http://www.itasoftware.com/ * This year, and for the first time, the workshop proceedings will be published in the ACM Digital Library. Overview ======== "...Please don't assume Lisp is only useful for Animation and Graphics, AI, Bio-informatics, B2B and E-Commerce, Data Mining, EDA/Semiconductor applications, Expert Systems, Finance, Intelligent Agents, Knowledge Management, Mechanical CAD, Modeling and Simulation, Natural Language, Optimization, Research, Risk Analysis, Scheduling, Telecom, and Web Authoring just because these are the only things they happened to list." -- Kent Pitman Lisp, one of the eldest computer languages still in use today, is gaining momentum again. The structure of Lisp makes it easy to extend the language or even to implement entirely new dialects without starting from scratch, making it the ideal candidate for writing Domain Specific Languages. Common Lisp, with the Common Lisp Object System (CLOS), was the first object-oriented programming language to receive an ANSI standard and retains the most complete and advanced object system of any programming language, while influencing many other object-oriented programming languages that followed. This workshop will address the near-future role of Lisp-based languages in research, industry and education. We solicit contributions that discuss the opportunities Lisp provides to capture and enhance the possibilities in software engineering. We want to promote lively discussion between researchers proposing new approaches and practitioners reporting on their experience with the strengths and limitations of current Lisp technologies. Programme ========= In addition to Edi Weitz's keynote address, the workshop will feature four technical papers and two tutorials. Please visit the programme web page (http://elw2009.bknr.net/programme) for a detailed description. Organizers ========== Didier Verna, EPITA Research and Development Laboratory, Paris Charlotte Herzeel, Programming Technology Lab, Vrije Universiteit, Brussel Robert Strandh, LaBRI, University of Bordeaux I, France Christophe Rhodes, Goldsmiths College, University of London Hans Hübner, Software Developer, Berlin -- Resistance is futile.

Boston Lisp Meeting: Monday 2009-06-29 Eli Barzilay on Implementing Domain Specific Languages with PLT Scheme. http://fare.livejournal.com/144600.html A Boston Lisp Meeting will take place on Monday, June 29th 2009 at 1800 at MIT 34-401B, where Eli Barzilay will speak about Implementing Domain Specific Languages with PLT Scheme. Additionally, we are still accepting proposals for up to two volunteers to each give of a 5-minute Lightning Talk (followed by 2-minute Q&A). Also, there will be a buffet offered by ITA Software. Registration is not necessary but appreciated. See details below. * Eli Barzilay will speak about Implementing Domain Specific Languages with PLT Scheme. Many problems call for domain-specific languages (DSLs) to express them and their solutions; such languages enable a dialogue between domain experts and software developers. The Lisp and Scheme community has a decades-old tradition of creating and embedding special-purpose languages via macros. Over the last twenty years, we PLT Schemers have continued to develop this technology to the point where making up new languages is so quick and easy that PROGRAMMERS CREATE A LANGUAGE FOR WRITING A SINGLE PROGRAM. Embedded DSLs are appropriate for a whole range of domains and applications -- in both academia and industry. Notable examples include research languages, teaching languages, and application-specific languages like our text-friendly documentation language. In this talk Eli will demonstrate how to implement embedded *practical* DSLs in PLT Scheme. Eli Barzilay is a Researcher in the PLT group at Northeastern University. He has been a core PLT Scheme developer since 2003, and has used PLT's ability to implement new languages to an extreme. For his Programming Languages undergraduate course, he creates nearly one language per week. In addition to writing new languages, he is involved in helping PLT develop into a multi-lingual environment. His website is at http://barzilay.org/ * * Having observed the success of the formula at ILC'2009, we have instituted Lightning Talks at the Boston Lisp Meeting. At every meeting, before the main talk, there are two slots for strictly timed 5-minute talks followed by 2-minute for questions and answers. The slots for next Monday are still open. Step up and come talk about your pet project! * * * The Lisp Meeting will take place on Monday June 29th 2009 at 1800 (6pm) at MIT, Room 34-401B.

REMINDER Boston Lisp Meeting: TUESDAY May 26th - Norman Ramsey on Using HOFs and CPS to Make Dataflow Optimization Simple http://fare.livejournal.com/144312.html A Boston Lisp Meeting will take place on Tuesday, May 26th 2009 at 1800 at MIT 34-401B, where Norman Ramsey will speak about Using Higher-Order Functions and Continuation-Passing Style to Make Dataflow Optimization Simple. Additionally, Ravi Nanavati will summon a Boston Area Haskell Users' Group meeting, and we are still accepting proposals for one 5-minute Lightning Talk (followed by 2-minute Q&A). Also, there will be a buffet offered by ITA Software. Registration is not necessary but appreciated. See details below. * Norman Ramsey will speak about Using Higher-Order Functions and Continuation-Passing Style to Make Dataflow Optimization Simple. Norman Ramsey's research spans theory (a foundational model for probabilistic programming languages) and practice (methods for making code generators reusable). While he has contributed to a variety of topics in programming languages and software engineering, his primary interests lie in functional programming and programming-language infrastructure. His introduction to functional programming came on a Symbolics Lisp machine, but shortly afterward he was seduced by the beauty of algebraic data types and pattern matching. These days his favorite programmable programming systems are Haskell (look! it has Prolog in the type checker and will generate your code for you!) and Lua (the best of scripting, metaobjects, and C rolled up into a tiny package). He is currently Associate Professor of computer science at Tufts University, a job which he enjoys tremendously except that it does not leave him time for enough programming. His website is at http://www.cs.tufts.edu/~nr/ * * Having observed the success of the formula at ILC'2009, we have instituted Lightning Talks at the Boston Lisp Meeting. At every meeting, before the main talk, there are two slots for strictly timed 5-minute talks followed by 2-minute for questions and answers. One slot for next Tuesday is still open. Step up and come talk about your pet project! * * * The Lisp Meeting will take place on Tuesday May 26th 2009 at 1800 (6pm) at MIT, Room 34-401B. Note that the meeting will NOT take place as usual on the last Monday of the Month, but on the next day, Tuesday. Indeed, that last Monday of May is Memorial Day, a holiday, and the next day thus makes do as a "Virtual Monday". As the numbers indicate, the room is in Building 34, on the 4th floor. This is the usual location, on 50 Vassar Street, Cambridge.

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 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. * * * * * The previous Boston Lisp Meeting on April 27th had 35 participants. Noah Goodman gave a talk about Lambda the Ultimate Gamble Alan Bawden also gave a Lightning Talk about a proposed better representation for quasiquotes. In the near future, we expect to have Bruce Lewis on 2009-07-27 about BRL http://brl.codesimply.net and ourdoings.com, Emmanuel Schanzer on 2009-08-31 about BootstrapWorld.org, and Christine Flood on some undetermined date about Fortress http://projectfortress.sun.com We are still looking for confirmed speakers for June, September, October. * * * * * * We're always looking for more speakers.
