Calico & the Resource monad, Scripting on the JVM, and Nix Hashbangs
We have three great talks for this in person event by three great speakers!
Calico: my love letter to the Resource monad
I will share the story of my inspiration for Calico, a library for building interactive web UIs using the Typelevel stack. At the heart of Calico's design is the Resource monad from Cats Effect. In this talk, we will encounter various kinds of resources and use the power of programs-as-values to express and compose them monadically. Along the way, we will learn about Cats Effect, FS2, and frontend web development.
Speaker
Arman Bilge
Hi there, I'm Arman! I am a member of the Typelevel community and a core maintainer of several projects, including Cats Effect. I also serve as the Executive Director of the Typelevel Foundation, where I help grow our community and support industry adoption of our libraries. I am interested in functional programming, concurrent runtimes, and how community and technology interact in open source - ask me how you can get involved with Typelevel!
About Typelevel
Typelevel is an ecosystem of projects and a community of people united to foster an inclusive, welcoming, and safe environment around functional programming in Scala. We work together to develop projects that apply functional programming to challenging problems relevant in industry. Our community culture embraces curiosity and mentoring and we don't shy away from experimenting with new and exciting ideas. Most of all, we love to make programming joyful and social!

Scripting on the JVM with Scala
This talk will explore the use of Scala as a scripting language, replacing the Bash and Python scripts common throughout the industry. We will walk through live-coded demonstrations of how the JVM's benefits of performance, compile-time safety, and vast library ecosystem are advantages over traditional script platforms, but also how language verbosity, build tool overhead, and lack of convenient libraries hampers the efforts. Lastly we will demonstrate how script-focused tooling is able to smooth over some of those issues, simplifying build configuration and providing suitable libraries to make the JVM truly a world-class scripting environment as robust as any scripting language out there.

Hashbang! Nix Makes Anything Executable
Hashbangs (#!) mark file executables at the kernel level. Nix (the program) extends this idea with an esoteric header format that lets Nix (the language) wrap and manage any script file. Pushing this further, Nix (the operating system) makes it easy to make any file executable. Learn about Nix, and the terrible things you can do in a single file to bootstrap a script.
