#.(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
