The working architecture of Perl applications — Viktor Turskyi, 45 minutes; accepted

I've seen a lot of Perl applications. I see a lot of misunderstandings around architectural patterns. 99% of Perl tutorials do not cover this topic and limited to "hello world" apps. How to build a really large application? What to choose Monolith or Microservices? How to think about architectural layers? How does GraphQL influence my architecture? I will answer all of these questions.

You Can Save The Planet. How About After Tea? — Sören Laird Sörries, 45 minutes; accepted

I don't mean to mock you, I don't think we will finish the task tonight. But I'd like to show it is feasible, and that it needs us to go about it and never stop.

Alternatively: What I have been doing and learning since the last PerlCon.

Console oriented sites and Perl 6: joining the worlds together — Igor Chubin, 20 minutes; accepted

Console sites or console services are sites that can be accessed from the browser or directly from the terminal, and though in both cases have the same or similar look and feel, accessing them from the terminal is usually preferable because of the advantages of the terminal itself. The question is, could Perl 6 become the main templating language for the console sites? And if yes, what main obstacles will be possibly faced on this way?

Why are there different implementations and which problem are they attempting to solve?
