Linux Day in Modena: an Introduction to Raku

Yesterday it was the Italian Linux Day, and after nine years I came back to this great event as a speaker in my own city, Modena.
I was at previous events, but as a participant, but this year I had the opportunity to speak again.

I decided to present an introductory talk about Raku, the title of the talk was “Il linguaggio della farfallina” (“The butterfly language”).
I’ve extracted the video recording of my talk (in italian) and placed it online:



The talk is a brief and quick introduction to Raku, and in order to demonstrate some features of the language I decided to implement the cat(1) Unix command in Raku. Therefore, I shown how to handle IO roles, how to use postfix operators like for and if, how to concatenate different method calls (method chaining), and how to deal with the topic.
The I explained about classes, and provided a controversial example about people and green pass and how roles can help mapping these concepts to data structures.
Last I did provide a quick example on grammars.
My slide were too much to be shown in the 40 minutes slot I had, but probably they will become available from the event organizers.

About the Linux Day 2021

The Linux Day has been organized perfectly by the Make It Modena and the local Linux User Group (LUG) Conoscere Linux.
Unluckily it was not possible to get it with live participant, so we (the speakers) were gathered in a room from which we were streaming the talks to high schools and other interested participants.
So far, I collected positive reactions.
The full video of the event is available on YouTube:



It is probably the first time in ten or more eyars that I deliver a talk that has nothing to do with PostgreSQL, and I always wanted to give a talk about Perl without finding out the right event, so I’m glad I had this opportunity.
