Hey Everyone, I hope you're doing well and staying safe. Sorry for the long wait between messages. As Didier just said the ELS will be online, yay! How's everyone doing? Fare, how's the startup, I miss the details. Jon

Hey Boston Lisp

I have been looking at Julia and its ecosystem in the last few months, and it is a very interesting experience. The language has full-strength Lisp macros, and full-strength multiple dispatch (so it is a full Lisp), while the user-facing syntax is not Lisp-like: https://docs.julialang.org/en/v1/manual/metaprogramming/ So it's both a Lisp and a non-Lisp. Generally speaking, people who creat Julia are consistently trying to "eat one's cake and to have it too", along multiple dimensions. Another axis is that the language is more flexible than Python, but is as fast as C. This is achieved via a very tasteful language design (the compiler is a normal competent LLVM compiler without miracles, it does not play any special role in this combination of expressiveness and speed). I have also found Julia open-source software on github unusually readable and easy to understand (it also tends to be very compact). The reason I was looking at Julia was that I was having an unusually flexible class of machine learning problems (a class of neural machines which is based on processing complicated structured data streams, and on using "flexible tensors" with tree-shaped indices; so one can do much more with these neural machines than with traditional neural nets). Even the most flexible Python frameworks, such as PyTorch, are too rigid for this class of problems, because they are oriented towards fixed multidimensional arrays ("tensors"). In this sense, Julia ecosystem seems to have a perfect fit, the Julia Flux machine learning framework, which is specifically oriented towards maximal flexibility and away from "tensors", while still being focused on high performance: https://github.com/FluxML/Flux.jl So far I was mostly reading other people's code, and doing small-scale explorations of my own (and creating publicly available notes in the process): https://github.com/anhinga/2020-julia-drafts I think that what I am trying to do with Julia Flux should be doable single-handedly (the tools seem to be that good), but I also hope to find collaborators (a small team would be able to move really fast with this). - Mishka On Tue, 14 Apr 2020, Jonathan Godbout wrote: > Hey Everyone, > I hope you're doing well and staying safe. > Sorry for the long wait between messages. > As Didier just said the ELS will be online, yay! > > How's everyone doing? > Fare, how's the startup, I miss the details. > > Jon > > >

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 13th European Lisp Symposium Special Focus on Compilers In cooperation with: ACM SIGPLAN Call for participation April 27 - April 28, 2020 Sponsored by EPITA, Igalia S.L., and RavenPack ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #COVID19 important information ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In the context of the current pandemic, the symposium has been turned into an online event, and will be open to anyone, free of charge! Connection instructions will be posted on the website when available. Invited Speakers ~~~~~~~~~~~~~~~~ Andrew W. Keep (Cisco Systems, Inc.), on the Nanopass Framework. Daniel Kochmański (Turtleware), on ECL, the Embeddable Common Lisp. Scope ~~~~~ 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 dialects, including Common Lisp, Scheme, Emacs Lisp, Clojure, Racket, ACL2, AutoLisp, ISLISP, Dylan, ECMAScript, SKILL and so on. We encourage everyone interested in Lisp to participate. This year's focus is directed towards "Compilers". Programme Chair ~~~~~~~~~~~~~~~ Ioanna M. Dimitriou H. - Igalia, Spain/Germany Local Chair ~~~~~~~~~~~ Nicolas Hafner - Shinmera, Switzerland Programme Committee ~~~~~~~~~~~~~~~~~~~ Andy Wingo - Igalia, Spain/France Asumu Takikawa - Igalia, Spain/USA Charlotte Herzeel - Imec, ExaScience Lab, Belgium Christophe Rhodes - Google, UK Irène Durand - Université Bordeaux 1, France Jim Newton - EPITA Research Lab, France Kent Pitman - HyperMeta, USA Leonie Dreschler-Fischer - University of Hamburg, Germany Marco Heisig - FAU Erlangen-Nürnberg, Germany Mark Evenson - not.org, Austria Max Rottenkolber - Interstellar Ventures, Germany Metin Evrim Ulu - Middle East Technical University, Turkey Paulo Matos - Igalia, Spain/Germany Robert Goldman - SIFT, USA Robert Strandh - Université Bordeaux 1, France Sky Hester - consultant, USA -- Resistance is futile.
