Wittenberger) Date: Wed, 9 Sep 2020 11:49:05 +0200 Subject: [gambit-list] Fix IPv6 support Message-ID: <20200909114905.3e13567f@devuan> Sorry, if this reaches you twice. Looks like I accidentally sent this out yesterday with github-noreply. The attached file `testtcp.scm` fails with gambit 0.9.2 here. With the attached patch applied it prints "Success!". Another sorry: the patch is against 0.9.2 since I can't build current master using 0.9.3 (and can't use 0.9.3 with lambdanative for testing). Otherwise the patch addresses the - to me at least surprising - fact that on my Linux box `sizeof(struct sockaddr)` is smaller than `sizeof(struct sockaddr_in6)`. Additionally it provides a sensible default for the local address to use with `open-tcp-client`. Best J?rg BTW: After too many failed attempts like `make from-scratch` etc. I'd really love to learn how build githug/master. -------------- next part -------------- A non-text attachment was scrubbed...

First call for papers ??????? 22nd Symposium on Trends in Functional Programming ????????????????????????? tfp2021.org ------------------------------------------------------------------------- The symposium on Trends in Functional Programming (TFP) is an international forum for researchers with interests in all aspects of functional programming, taking a broad view of current and future trends in the area. It aspires to be a lively environment for presenting the latest research results, and other contributions. * TFP offers a supportive reviewing process designed to help less experienced ? authors succeed, with two rounds of review, both before and after the ? symposium itself. Authors have an opportunity to address reviewers' concerns ? before final decisions on publication in the proceedings. * TFP offers two "best paper" awards, the John McCarthy award for best paper, ? and the David Turner award for best student paper. * TFP is co-located with Lambda Days in beautiful Krakow. Lambda Days is a ? vibrant developer conference with hundreds of attendees and a lively programme ? of talks on functional programming in practice. Due to the covid pandemic, ? the event is online with a lot of attention to interaction and getting to ? socialize with the community. Important Dates --------------- Submission deadline for pre-symposium review:???? 20th November, 2020 Submission deadline for draft papers:???????????? 15th January, 2021 Symposium dates:????????????????????????????????? 17-19th February, 2021 * We strongly encourage authors to submit their work for the first deadline. ? Authors whose papers are accepted for presentation, but not immediately for the ? proceedings in this first round, will have almost two months to address the ? reviewers' concerns. Papers submitted for the first deadline will also have ? priority for the presentation slots at the symposium. Visit tfp2021.org for more information.

TFPIE 2021 Call for papers -------------------------------- https://wiki.tfpie.science.ru.nl/TFPIE2021#TFPIE_2021 (February 16 2021, co-organized with TFP 2021 and Lambda Days 2021) The goal of the International Workshops on Trends in Functional Programming in Education is to gather researchers, professors, teachers, and all professionals that use or are interested in the use of functional programming in education. TFPIE aims to be a venue where novel ideas, classroom-tested ideas, and work in progress on the use of functional programming in education are discussed. The one-day workshop will foster a spirit of open discussion by having a review process for publication after the workshop. TFPIE 2021 welcomes submissions in the above mentioned areas. This year many teaching programmes have had to make a rapid transition to online teaching, and we explicitly solicit papers that explore this area of teaching functional programming. Topics of interest include, but are not limited to: -? FP and beginning CS students -? FP and Computational Thinking -? FP and Artificial Intelligence -? FP in Robotics -? FP and Music -? Advanced FP for undergraduates -? FP in graduate education -? Engaging students in research using FP -? FP in Programming Languages -? FP in the high school curriculum -? FP as a stepping stone to other CS topics -? FP and Philosophy -? The pedagogy of teaching FP -? FP and e-learning: MOOCs, automated assessment etc. -? Best Lectures - more details below In addition to papers, we are requesting best lecture presentations. What's your best lecture topic in an FP related course? Do you have a fun way to present FP concepts to novices or perhaps an especially interesting presentation of a difficult topic? In either case, please consider sharing it. Best lecture topics will be selected for presentation based on a short abstract describing the lecture and its interest to TFPIE attendees. The length of the presentation should be comparable to that of a paper. On top of the lecture itself, the presentation can also provide commentary on the lecture. Submissions Potential presenters are invited to submit an extended abstract (4-6 pages) or a draft paper (up to 20 pages) in EPTCS style. The authors of accepted presentations will have their preprints and their slides made available on the workshop's website. Papers and abstracts can be submitted via easychair at the following link: https://easychair.org/conferences/?conf=tfpie2021 After the workshop, presenters are invited to submit (a revised version of) their article for review. The PC will select the best articles. We plan to publish them in the Electronic Proceedings in Theoretical Computer Science (EPTCS). Articles rejected for presentation and extended abstracts will not be formally reviewed by the PC. Dates -? Submission deadline: January 11 2021, Anywhere on Earth. -?

I recall you said something to this effect in the past. Thought came to mind now, that what about that Gambit could have use of an |apply| form that takes a vector as argument, due to prevalence of speed benefit of vector over list. Please share your thoughts on this one. Adam -------------- next part -------------- An HTML attachment was scrubbed... URL:
