Online Lisp Meeting #6

#.(ALEXANDRIA:RANDOM-ELT *OLM-MAIL-GREETINGS*) Our speakers for the sixth Online Lisp Meeting are Jan Moringen, a major SBCL contributor, and Hayley Patton, a Lisp object farmer. Jan Moringen will talk about Clouseau, a CLIM-based implementation of the Common Lisp inspector facility. > An inspector is a software tool the purpose of which is the > interactive inspection and manipulation of values and their relations > within a running program. Besides more prominent components such as > editors and debuggers, inspectors play an important role in > interactive development environments or just interactive environments > in general. Common Lisp and Common Lisp-based environments have a > long history of inspectors: Genera's inspector, CL:INSPECT, the SLIME > inspector and McCLIM's two inspectors called Clouseau, to name a few. > > This presentation is about the latter two: the original Clouseau and, > more importantly, the redesigned and rewritten implementation that > replaced it. After mentioning a few crucial requirements and design > decisions, the presentation focuses on a user's perspective. It > demonstrates the basic use, specialized visualizations and operations > and customization of the rewritten Clouseau. Hayley Patton will talk about Techniques and Utilities for Farming Objects On The Net. > This presentation is about programming concurrent, distributed systems > in Common Lisp, and some of the ideas that have sprung up while > developing the Netfarm distributed object system. We will demonstrate > how we try to abstract away wire protocol and format differences, how > we can use a recommender system to filter unwanted content for an end > user in the Netfarm system; and some libraries we have worked on, with > the aim to produce performant and robust concurrent Lisp programs. 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. * Date: 5th August 2020 * Time: 13:00 CEST - https://time.is/en/CEST * Talk: https://www.twitch.tv/TwitchPlaysCommonLisp * Hangout: https://chat.heisig.xyz/TwitchPlaysCommonLisp @ 19:00 CEST Massive thanks to Marco Heisig for providing the Jitsi instance where we can hang out after the talk. (This time I've actually put in an hour for that! That's a part of success.) 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

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.
