Once a month, we meet and someone gives a presentation about technical issues about the Perl programming language, the Raku programming language or the world surrounding them. Past topics include programming best practices, grammars, graphQL, reactive programming, anagrams, Perl 5 core maintenance, and more. Generally our speakers come from within phl.pm, but from time to time we bring in a guru from elsewhere in the community.

Our upcoming meetings are listed on our events page.
