Online Lisp Meeting #5
by Michał "phoe" Herda 22 Jul '20

22 Jul '20

Good morning, everyone! We officially start running out of fingers on a single hand, because this Online Lisp Meeting shall be the fifth one. We will have a pair of speakers this time: Bonface Munyoki, a software developer with a keen interest in functional programming, and Robert Strandh of SICL fame. Bonface will talk about Guix Past: > In the field of software development, libraries and tools evolve quickly > to keep up with trends, improvements in hardware or to work around > discovered/ exposed vulnerabilities. People, across diverse fields, > adapt their work by updating the libraries they use to keep up. For > scientists, that normally does not happen. Rarely will people maintain > the code they wrote for a paper they published; instead, it's the > impetus of the reader to reproduce the code based off the paper they > read. Outside academic papers, for long-living projects like > genenetwork¹, it would be desirable to provide a "time-machine" that > enables the user to jump between various past versions. Guix past³ is a > project initiated by Guix-HPC² that aims to provide these old, sometimes > archived libraries to users with the goal of enabling people to > reproduce old builds of software they used a couple of years ago. > > ¹ https://en.wikipedia.org/wiki/GeneNetwork > ² https://hpc.guix.info/ > ³ https://gitlab.inria.fr/guix-hpc/guix-past Robert will continue talking about creating a Common Lisp implementation with part 2 of his talk. > In this series of presentations, we examine different strategies for > creating a Common Lisp implementation, as well as the pros and cons of > each strategy. > > We assume basic knowledge about how a typical modern operating system > (such as Unix) works, and how traditional batch languages (such as C) > are compiled and executed on such a system. We furthermore assume > medium-level knowledge about Common Lisp. > > In part 2, we sketch a possible compiler that generates byte codes, > and an abstract machine for interpreting such byte codes. As before, the talk will be pre-recorded and played back on Twitch, with the ability to comment on the Twitch chat during playback. The videos will make it onto YouTube. In my evening, I plan on organizing an online drink and chat on Jitsi (I know that I promised you that the last time and didn't deliver - I wholeheartedly apologize.) - let's discuss that on #lispcafe. Date/time/location: * Date: 22nd July 2020 * Time: 13:00 CEST - https://time.is/en/CEST * Talk: https://www.twitch.tv/TwitchPlaysCommonLisp * Hangout: https://chat.heisig.xyz/TwitchPlaysCommonLisp Massive thanks to Marco Heisig for providing the Jitsi instance where we can hang out after the talk. (Ha! No one noticed that I called him Macro in the previous mail. Strangely suitable, anyway.) A mailing list has been created for the purpose of organizing and promoting the online talks. Further announcements will be posted there. See https://mailman.common-lisp.net/listinfo/online-lisp-meets If you'd like to submit something yourself, please feel free to. The slots are almost always open - there's no real queue for these videos. BR and see you! Michał "phoe" Herda

Good morning, everyone! It's time to have an Online Lisp Meeting for the fourth time. Robert Strandh will once again talk, this time about creating Common Lisp implementations! > In this series of presentations, we examine different strategies for creating a Common Lisp implementation, as well as the pros and cons of each strategy. > > We assume basic knowledge about how a typical modern operating system (such as Unix) works, and how traditional batch languages (such as C) are compiled and executed on such a system. We furthermore assume medium-level knowledge about Common Lisp. > > In part 1, we compare the issues of creating a Common Lisp implementation to the issues of writing a compiler for a traditional batch language for a typical modern operating system. Given these issues, we investigate some strategies for creating a compiler for a Common Lisp system, and we examine the requirements on the run-time environment for the compiled code to be executable in that environment. As before, the talk will be pre-recorded and played back on Twitch, with the ability to comment on the Twitch chat during playback. The videos will make it onto YouTube. In my evening, I plan on organizing an online drink and chat on Jitsi - let's discuss that on #lispcafe. Date/time/location: * Date: 29th June 2020 * Time: 13:00 CEST - https://time.is/en/CEST * Talk: https://www.twitch.tv/TwitchPlaysCommonLisp * Hangout: https://chat.heisig.xyz/TwitchPlaysCommonLisp Massive thanks to Macro Heisig for providing the Jitsi instance where we can hang out after the talk. A mailing list has been created for the purpose of organizing and promoting the online talks. Further announcements will be posted there. See https://mailman.common-lisp.net/listinfo/online-lisp-meets (I really think that I should customize the part where I ask everyone to submit their own talks or Lispy things they'd like to share, so, I guess that's what I am doing right now. Please throw them at me and I'll be happy to host them!) BR and see you! Michał "phoe" Herda

Online Lisp Meeting #3

15 Jun '20

Good morning, everyone! I am pleased to announce the third Online Lisp Meeting. There are two speakers for the third Online Lisp Meeting: Mark Evenson, the current maintainer of Armed Bear Common Lisp, and Robert Strandh, the initiator of SICL, the upcoming modular implementation of Common Lisp. Mark Evenson will talk about "Reflections on the Future History of Arming Bears". > With the recent releases of Armed Bear Common Lisp over the past six > months, the future of extending the implementation has come into > sharper focus. The majority of this work has occurred within the head > of one individual with little chance for public review and reflection, > we believe that an externalized exposition of the reasoning behind > these efforts would be of interest to those interested in the future > history of Common Lisp implementations. > > Most notably, with abcl-1.6.0 we extended the set of underlying Java > Virtual Machines (JVM) that the implementation runs on to include > openjdk11 and openjdk14 while maintaining compatibilty with openjdk6. > And with the internal overhaul or arrays specialized on unsigned bytes > in abcl-1.7.0, we made it possible to share such byte vectors with > memory allocated outside of the hosting JVM via system interfaces such > as malloc(). We first present the goals and challenges in affecting > these changes within the ABCL codebase. Then, we use this initial > exposition to serve as a springboard to discuss outstanding needed > changes in the ABCL 1 branch, and to outline some of the features > intended to be present in ABCL 2, due to be released in the Fall of 2020. > Robert Strandh will talk about First-Class Global Environments in Common Lisp. > At the European Lisp Symposium in 2015, we presented a paper entitled > "First-class Global Environments in Common Lisp". There are several > possible use cases for such environments. In this presentation, we > investigate the use of such environments at run time for so-called > "sandboxing", i.e., to allow only a pre-selected set of > functionalities to be visible to application code. In particular, we > demonstrate the main idea that allows such environments to be used > with no performance loss in almost all cases. As before, the talk will be pre-recorded and played back on Twitch, with the ability to comment on the Twitch chat during playback. Afterwards, we will have an online drink and chat on Jitsi. The videos will then make it onto YouTube. Date/time/location: * Date: 15th June 2020 * Time: 13:00 CEST - https://time.is/en/CEST * Talk: https://www.twitch.tv/TwitchPlaysCommonLisp * Hangout: https://chat.heisig.xyz/TwitchPlaysCommonLisp Massive thanks to Marco Heisig for providing the Jitsi instance where we can hang out after the talk.

Fwd: Online Lisp Meeting #2
by Michał "phoe" Herda 01 Jun '20

01 Jun '20

Good news, everyone! It is time to announce the second Online Lisp Meeting. This time, the speaker will be Michael Raskin of [`agnostic-lizard`](https://gitlab.common-lisp.net/mraskin/agnostic-lizard) fame; he will talk about **Query-FS: Integrating with UNIX from Common Lisp via FS API**. > The talk is about Query-FS, a virtual filesystem representing various queries (for example, SQL queries to a database) as directories. There will be a demo of what basic usage looks like, and an explanation of how it works inside. > Warning: while Query-FS is implemented is Common Lisp, its goal is integrating with non-Lisp things across a POSIX-defined interface. It probably makes little sense in an environment integrated around a single program (such as Emacs). And some included DSLs even look vaguely similar to Bash. So, it is a tool in Common Lisp for non-Lispy use. As before, the talk will be pre-recorded and played back on Twitch, with the ability to comment on the Twitch chat during playback. Afterwards, we will have an online drink and chat on Jitsi. Date/time/location: * Date: 1st June 2020 * Time: 13:00 CEST - https://time.is/en/CEST * Talk: https://www.twitch.tv/TwitchPlaysCommonLisp * Hangout: https://chat.heisig.xyz/TwitchPlaysCommonLisp * Slides: https://gitlab.common-lisp.net/cl-fuse/query-fs/-/wikis/Main-page Massive thanks to Marco Heisig for providing the Jitsi instance where we can hang out after the talk. A mailing list has been created for the purpose of organizing and promoting the online talks. Further announcements will be posted there.

Online Lisp meeting series
by Michał "phoe" Herda 12 May '20

12 May '20

Hello! First and foremost, massive thanks to all the organizers, all the speakers, and all the participants of European Lisp Symposium 2020 - the first and greatest fully online edition of the conference, surprisingly nice and wonderful in its own unique way. The recordings are available at https://www.twitch.tv/elsconf/videos Since the new formula turned out to be good and we are still likely going to be stuck in homes for the forthcoming weeks, I have decided to start a more cyclic Lisp meeting that is smaller in programme but more frequent in time, so we have more chances to meet and hang out with members of our Lisp community - even if just via chat and webcams. Similar to the ELS, the talk will be pre-recorded and streamed on Twitch with live chat available during the talk. Then, everyone is invited to participate in an online discussion and after-party on Jitsi with webcams and microphones. We can hang out, chat, comment, gossip, have a virtual drink, and make some plans for the next meetings. I can bootstrap the series. I will talk about multiple independent condition systems in a single Common Lisp image. I will use an example where I want to integrate two distinct condition/restart systems under one debugger: a host one provided by the Lisp implementation, and an independent and portable condition system. Date/time/location: * Date: 12th May 2020 * Time: 18:00 CEST - https://time.is/en/CEST * Talk: https://www.twitch.tv/TwitchPlaysCommonLisp * Hangout: https://chat.heisig.xyz/TwitchPlaysCommonLisp Massive thanks to Marco Heisig for providing the Jitsi instance where we can hang out after the talk. A new mailing list has been created for the purpose of organizing and promoting the online talks. Further announcements will be posted there. See https://mailman.common-lisp.net/listinfo/online-lisp-meets Everyone, please feel free and welcome to suggest your own ideas and record something that you'd like to talk about and share. BR and see you, Michał "phoe" Herda
