How I publish microblog messages to my blog, mastodon and my .signatur

Das ist ein Bericht, was sich bei meinen graphischen CPAN-Modulen tat. Updates für Graphics::Color::Toolkit, Graphics::ColorNames::* aber vor allem beim Harmonographen, Juliagraphen, Cellgraphen und vielleicht sind auch schon neue Module hinzugekomme

I have been doing AI with Perl for a few decades. Now - 3 decades into Perl - I think it is time to turn the predicate around and let AI do Perl

In the world of cricket, T20, ODI, and Test matches represent distinct formats, each demanding a unique strategic mindset. Software development mirrors this diversity: the solution changes based on size, scale, and timeline, shifting from the rapid-fire execution of a one-liner to the long-term endurance required for enterprise systems.
