Code BEAM Lite Stockholm

June 02 - June 02, 2025

The Conference for Erlang and Elixir Developers in Sweden Meet people and companies using and developing high performance, fault-tolerant and resilient applications that scale to billions of users in production in areas like Fintech, eCommerce, IoT, Gaming, Blockchain, Security, Machine Learning and more. Code BEAM Stockholm is in the home of Erlang and has a strong community of developers from the Nordics. Come and join us to learn from each other, share knowledge and be inspired all while growing your network of contacts.

More advanced developers will appreciate that our programme is packed with cutting-edge thought provoking talks. At Code BEAM Lite Stockholm we will uncover how BEAM languages are transforming areas like IoT, Fintech, Machine Learning, Blockchain, Security and more!

Developers of every level can expect to learn from each other, share knowledge all while growing our community reach in the Nordics.

Erlang Workshop 2025

October 12 - October 12, 2025

General Information Welcome to the website of the Erlang 2025 workshop!

Series Erlang 2025 is the 24rd ACM SIGPLAN Erlang Workshop and is a satellite event of the 30th ACM SIGPLAN International Conference on Functional Programming (ICFP 2025).

Scope The workshop aims to bring together the open source, academic, and industrial communities of Erlang, other BEAM-related languages, actor model programming, distribution, and concurrency to discuss techniques, technologies, languages, and other relevant topics. The Erlang model of concurrent programming has been widely emulated, for example, by Akka in Scala. Moreover, several newer programming languages, such as Elixir, have been designed atop Erlang’s VM. The workshop welcomes contributions related to any and all systems like those mentioned above.

Proceedings As with previous years, the accepted workshop papers will be published by the ACM and will appear in the ACM Digital Library.

Goals The workshop aims to enable participants to learn about recent developments in techniques and tools, novel applications, draw lessons from users’ experiences, and identify research problems and common areas relevant to the practice of Erlang and other Erlang-like languages, functional programming, actor model programming, distribution, concurrency, etc.

We are looking forward to your participation!

Func Prog Sweden April 2025 at Kivra

October 16 - October 16, 2025

Details Welcome to the third Func Prog Sweden MeetUp 2025 – Online

This MeetUp will be streamed live online on the Func Prog Sweden YouTube channel: https://www.youtube.com/c/FuncProgSweden

The program starts at 18:00 / 6 PM:

Intro by Magnus Sedlacek Boost your command-line applications with potions! by Eric Torreborre Dependent types are everywhere! by Elisabeth Stenholm Post-show chat Boost your command-line applications with potions! How hard can it be to parse command-line arguments for an application? My initial, and foolish, answer was “not too hard”. Thanks to this misplaced over-confidence this talk presents potions, a command-line arguments parsing library written in Unison (https://unison-lang.org).

We will start with a tour of the library features: various type of options, support for environment variables, styled help, and more. We will then dive into the implementation of the library, where the main workhorse is (drum roll) Unison’s effect system called “abilities”.

We’ll see what can be checked at compile-time, what can’t, how abilities are layered to provide different DSLs (domain-specific languages), how they can be used to enclose state for mutually recursive functions, etc…

Finally, I will talk about some of the issues that slowed me down during the development, and why I feel that a full-fledge Unison IDE will be indispensable for any medium to large scale project.

Eric Torreborre I am a Rust/Elixir developer working at Ockam where we enable private systems to communicate without exposing their network to the Internet (ask me more if you’re interested!). I am also a functional programmer at heart, having professional experience with both Scala and Haskell which I enjoyed very much!

Dependent types are everywhere! Have you ever heard of dependent types? Even if you have not, chances are you have most likely encountered some data structure that is actually dependently typed, without knowing it. In this talk I will explain what dependent types are and why they are everywhere, we just don’t notice them as we are so used to living without them. With dependent types we can express our structures more correctly, giving us more guarantees compile time. As a concrete example I will share my recent experience with writing a small questionnaire with a web frontend, all the parts of this construction that are actually dependently typed, and the differences between writing it with and without dependent types.

Elisabeth Stenholm Elisabeth is 32 years old, born in Uppsala and raised in Stockholm. She has a PhD in dependent type theory from the University of Bergen, and is currently working as a fullstack developer at Frende Forsikring — a Norwegian insurance company based in Bergen. In her workday, Elisabeth writes primarily in the functional languages F# and Elm. She is passionate about type theory and functional programming, and enjoys sharing her knowledge on these topics with others.
