"Perl 5 was my rewrite of Perl. I want Perl 6 to be the community's rewrite of Perl and of the community." - Larry Wall (circa 2000)
"I am in favor of this change [a community driven renaming from Perl 6 to Raku], because it reflects an ancient wisdom: 'No one sews a patch of unshrunk cloth on an old garment, for the patch will pull away from the garment, making the tear worse. Neither do people pour new wine into old wineskins. If they do, the skins will burst; the wine will run out and the wineskins will be ruined. No, they pour new wine into new wineskins, and both are preserved.'" - Larry Wall (2019)
IRC communication has played an integral role in the Raku community for more than a decade. There are various channels for Raku-related activities on
libera.chat. There are several bots to make IRC activity more convenient and fun. You can read about IRC content here in greater details.
The Raku Discord server serves a similar purpose. Thanks to the bridges written by fellow Raku members, it integrates well with the main IRC channels.
StackOverflow is also a great resource for asking questions and helping others with their Raku problems and challenges.
More resources can be found in the raku.org community page.
Camelia, the multi-color butterfly with P 6 in her wings, is the symbol of this diverse and welcoming community.
Elizabeth Mattijsen usually posts in the "Rakudo Weekly" blog, a summary of Raku posts, tweets, comments and other interesting tidbits. If you want a single resource to know what is going on in the Raku community now, this is your best resource.
Historical articles (pre name change) can be found archived on the "Perl 6 Weekly" blog.
Organization and assignment of days is done through the different Raku channels and the Raku/advent repository. If you want to participate, its organization starts by the end of October, so check out the channels above to keep up to date.
