~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 15th European Lisp Symposium Call for Participation March 21-22, 2022 FEUP, Porto, Portugal & Online In cooperation with ACM SIGPLAN https://www.european-lisp-symposium.org/2022 Sponsored by EPITA, Franz Inc., and SISCOG ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Important News ~~~~~~~~~~~~~~~ - Full programme now online - Invited speakers below - Registrations are open Scope ~~~~~ The European Lisp Symposium is a premier forum for the discussion and dissemination of all aspects of design, implementation and application of any of the Lisp dialects, including Common Lisp, Scheme, Emacs Lisp, Clojure, Racket, ACL2, AutoLisp, ISLISP, Dylan, SKILL, Hy, Shen, Carp, Janet, uLisp, Picolisp, Gamelisp, TXR, and so on. We encourage everyone interested in Lisp to participate. The 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 Invited talks ~~~~~~~~~~~~~ Building SICMUtils, the Atelier of Abstractions -- Sam Ritchie SICMUtils is a Clojure library designed for interactive exploration of mathematical physics. It is simultaneously a work of persuasive writing, a collection of essays on functional pearls and computational ideas, a stable of workhorse functional abstractions, and a practical place to work and visualize algorithms and physical systems, on a server or in the browser. How do you build a library like this? This talk will go through the architecture of SICMUtils, based on many of the ideas of "additive programming" from Gerald Sussman and Chris Hanson's latest book, Software Design for Flexibility. We'll look at surprising examples of the system becoming easier to extend over time. Clojure's embrace of its host platform lets us use the best modern work in Javascript for visualization, while keeping the horsepower of our servers for real work. Lisp's particular elegance will shine throughout. Creating a Common Lisp Implementation -- Robert Strandh Being dissatisfied with the way current Common Lisp implementations are written, and with the duplication of system code between different implementations, we started the SICL project in 2008. The initial idea was to create modules that the creators of Common Lisp implementations could use to create a complete system from an initial minimal core. But this idea was unsatisfactory because it required each module to be written in a subset of Common Lisp. So instead, we decided to use the full language to implement these modules, effectively making them useless to an implementation using traditional bootstrapping techniques. We therefore decided to also create a new Common Lisp implementation (also named SICL), that could use those modules. A crucial element is a bootstrapping technique that can handle these modules. In this spirit, we have developed several modules, including an implementation of CLOS which is also an important element of bootstrapping. Lately, we have increased our level of ambition in that we want to extract those modules as separate (and separately maintained) repositories, which requires us to deal with code during bootstrapping that was not specifically written for SICL. In our talk, we describe this evolution of ambition, and its consequences to bootstrapping, in more detail. We also give an overview of several new techniques we created, some of which have been published (at ICL and ELS) and some of which have not. Finally, we discuss the future of the project, and other projects for which we imagine SICL to be a base. Lisp as Renaissance Workshop: A Lispy Tour through Mathematical Physics -- Sam Ritchie Lisp is an exquisite medium for the communication of computational ideas. From our most accurate observations of physical reality up through chemistry, biology, and cognition, the universe seems to be computing itself; modeling and simulating these systems in machines has led to incredible technological wealth. Deep principles and beautiful abstractions seem to drive these systems, but they have always been hard to discover; and we are floundering at the computational frontiers of intelligence, synthetic biology and control systems for our climate. The only way to push forward is to build powerful tools that can communicate and teach. This talk will take a tour through SICMUtils, a Lisp system designed as a workshop for conducting serious work in mathematical physics and sharing those explorations in a deeply interactive, multiplayer way. The library’s growth parallels our human scientific history; hopefully tools like this will help us write the next chapter.
