Talk in Boston: Lisp, LLVM, Molecular Lego
by Martin Cracauer 20 Nov '18

20 Nov '18

On June 9 I will host Christian Schafmeister for a talk about "Clasp: Common Lisp using LLVM and C++ for Molecular Metaprogramming". It is the talk he gave on the ELS2015 on London and I liked it a lot. It was one of many knockout talks on that conference. Lisp has come a long way. I am very happy Christian can give the talk locally. This event is in the Google office at Kendall Red Line station. External guests are invited. We have to do the full run with upfront registration, visitor pass and assigned Googler (aka me unless we get a lot of guests). So if you would like to come please let me know soon. If you have friends who might be interested in "Molecular Lego" please forward. The talk is about programming but the molecular part is very good. Same for general LLVM enthusiasts you might know. Planned time is June 9, 2015 12:00-13:00. You would need to be early because I can't set up Christian and get you in at the same time. PLEASE CONFIRM TIME in case there are changes. Abstract: Clasp is an implementation of Common Lisp that interoperates with C++ and uses LLVM as its backend. It is available at github.com/drmeister/clasp. The goal of Clasp is to become a performant Common Lisp that can use C++ libraries and interoperate with LLVM-based tools and languages. The first sophisticated C++ library with which Clasp interoperates is the Clang C/C++ compiler front end. Using the Clang library, Common Lisp programs can be written that parse and carry out static analysis and automatic refactoring of C/C++ code. This facility is used to automatically analyze the Clasp C++ source code and construct an interface to the Memory Pool System compacting garbage collector. The primary purpose of Clasp is to act as a performant language for scientific computing that will be used to design sophisticated new molecular devices, catalysts and therapeutic molecules based on our "Molecular Lego" technology. Clasp is a general programming language that will support many other applications.

ELS'19 - 12th European Lisp Symposium Hotel Bristol Palace Genova, Italy April 1-2 2019 In co-location with <Programming> 2019 Sponsored by EPITA http://www.european-lisp-symposium.org/2019/ The purpose of the European Lisp Symposium is to provide a forum for the discussion and dissemination of all aspects of design, implementation and application of any of the Lisp and Lisp-inspired dialects, including Common Lisp, Scheme, Emacs Lisp, AutoLisp, ISLISP, Dylan, Clojure, ACL2, ECMAScript, Racket, SKILL, Hop and so on. We encourage everyone interested in Lisp to participate. The 12th European Lisp Symposium invites high quality papers about novel research results, insights and lessons learned from practical applications and educational perspectives. We also encourage submissions about known ideas as long as they are presented in a new setting and/or in a highly elegant way. Topics include but are not limited to: - Context-, aspect-, domain-oriented and generative programming - Macro-, reflective-, meta- and/or rule-based development approaches - Language design and implementation - Language integration, inter-operation and deployment - Development methodologies, support and environments - Educational approaches and perspectives - Experience reports and case studies We invite submissions in the following forms: Papers: Technical papers of up to 8 pages that describe original results or explain known ideas in new and elegant ways. Demonstrations: Abstracts of up to 2 pages for demonstrations of tools, libraries, and applications. Tutorials: Abstracts of up to 4 pages for in-depth presentations about topics of special interest for at least 90 minutes and up to 180 minutes. The symposium will also provide slots for lightning talks, to be registered on-site every day. All submissions should be formatted following the ACM SIGS guidelines and include ACM Computing Classification System 2012 concepts and terms. Submissions should be uploaded to Easy Chair, at the following address: https://www.easychair.org/conferences/?conf=els2019 Note: to help us with the review process please indicate the type of submission by entering either "paper", "demo", or "tutorial" in the Keywords field. Important dates: - 01 Feb 2019 Submission deadline - 01 Mar 2019 Notification of acceptance - 18 Mar 2019 Final papers due - 01-02 Apr 2019 Symposium Programme chair: Nicolas Neuss, FAU Erlangen-Nürnberg, Germany Programme committee: tba Search Keywords: #els2019, ELS 2019, ELS '19, European Lisp Symposium 2019, European Lisp Symposium '19, 12th ELS, 12th European Lisp Symposium, European Lisp Conference 2019, European Lisp Conference '19 -- Resistance is futile.

Boston Lisp 2018-11-02 Marc Feeley: Compiling for Multi-language Task Migration
by fare＠tunes.org 22 Oct '18

22 Oct '18

The Boston Lisp Meeting Returns on Friday November 2nd 2018 at 7pm at the MIT Stata Center Star Conference Room 32-D463 Marc Feeley Professor at Université de Montréal Author of Gambit Scheme will visit us and give a talk on Compiling for Multi-language Task Migration Task migration allows a running program to continue its execution in a different destination environment. Increasingly, execution environments are defined by combinations of cultural and technological constraints, affecting the choice of host language, libraries and tools. A compiler supporting multiple target environments and task migration must be able to serialize continuations and then deserialize and continue their execution, ideally, even when the language of the destination environment is different. In this talk, I will describe a compilation approach based on a virtual machine that strikes a balance between implementation portability and efficiency. This approach is implemented in the Gambit Scheme compiler and it targets JavaScript, PHP, Python, Ruby and Java—some of the most popular host languages for web applications. Experiments show that it compares well with other Scheme compilers targeting high-level languages in terms of execution speed, being sometimes up to 3 orders of magnitude faster.

Announcing the Boston Lisp Meeting
by Faré 22 Oct '18

22 Oct '18

I created the attached placard for the next meeting. 1- Are there any volunteers to post it in various places of interest near you? Universities, places of work, etc. 2- Can you suggest suitable mailing-lists to which to forward the announcement? 3- I created the short url j.mp/BostonLisp for https://common-lisp.net/project/boston-lisp/ but the site hasn't been updated since 2009. Oops. Is there any volunteer to keep the website updated? 4- I propose said website be kept in git for collaborating without overwriting each other. 5- Unless some other volunteer objects, I will be using PLT Scribble to generate HTML. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org The hacker: someone who figured things out and made something cool happen. — Alan Schmitt

Dear Marc, I've confirmed the Star room at the MIT Stata Center for your talk on November 2nd at 1900. Can you give me a title and abstract for your presentation? —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org Beware of altruism. It is based on self-deception, the root of all evil. — Robert Heinlein, "Time Enough For Love"
