Boston Elixir Meetup: “Starting a business with Phoenix LiveView and Event Sourcing"

August 13 - August 13, 2025

Aaron Votre, who is a Lead Developer at Bright Harbor and previously at Corvus Insurance, will be giving a talk on event sourcing, the commanded library, and how at Bright Harbor they pair it with LiveView.

This is not an introductory tutorial on event sourcing, this talk focuses more on its practical applications and business impact.

There may also be time afterwards for anyone to demo any project they wish to share afterwards.

Sixth Func Prog Sweden 2025

August 19 - August 19, 2025

Welcome to the sixth 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.

• Intro by Magnus Sedlacek
• Rust vs. F# by Johan Olsson
• Turn old into new: Moving to elixir feature by feature by Anita Ludermann
• Post-show chat

Rust vs. F# F# is a multi-purpose functional-first language using the .NET ecosystem and runtime.

Rust is a systems-level functional-style language focused on memory safety.

This talk will compare these two languages, their similarites, differences, strengths and weaknesses. We will also discuss when you would choose one over the other.

Johan Olsson Johan Olsson is a software developer and a consultant at TheTribe, known for his expertise in Microsoft technologies and a longstanding passion for functional programming. He has 35+ years experience as a professional programmer, but started coding back in the dark ages (the early eighties). https://www.linkedin.com/in/jolsson800/

Turn old into new: Moving to elixir feature by feature It’s 2022 and our software feels like 1999. Our developer pace is fine but the habitat is crumbling, the technology is outdated. So in January 2023, we took the plunge and started building the new town over in Elixir Land.

In this talk, we share our approach to the technology shift and how we integrate this long term goal into our business as usual where we focus on modern software engineering with small incremental steps. We’ll take a look at the challenges we have faced and are still facing, some of which are: communicating between old and new system, shifting to functional programming, making existing data usable in Ecto, building bridges and shifting traffic and last but not least doing this all without the user noticing. We’ll also take a look at a real life feature that went from ugly duckling to shiny new with the help of the strangler fig pattern.

Anita Ludermann Software Engineer at Modell Aachen GmbH Anita Ludermann is a seasoned software engineer with over a decade of expertise. At Modell Aachen GmbH, she has worked extensively with the Elixir programming language, test-driven development and domain driven design. Together with her collagues, she modernizes the legacy codebase into a modern, maintainable solution.

In addition to her technical work, Anita is committed to fostering community and supporting others in tech. As the co-founder of Ladybugs Aachen, she creates opportunities for women in software development to connect, share knowledge, and grow their skills.

Drawing from her experience in legacy system transformation and her passion for collaboration, Anita offers practical insights into leveraging Elixir for building modern software solutions. https://www.linkedin.com/in/anita-ludermann/

Post-show chat Once the live stream is over we will do a post show chat on the FPS Discord Server, where you can join and ask questions and meet more community members (this will no be recorded).

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.
