A small announcement with big feelings:
Lambda Days won’t be happening in 2026. It’s a difficult moment for us - this conference has always been about people, passion, and the FP community coming together.
To keep that spirit alive, we’ve released:
🎬 All 2025 talk recordings, now available to everyone!
👉 youtube.com/playlist?list=PL…
We hope they bring you inspiration until we meet again.
Dear FP Community,
Even though we're on a break this year, there are still many great gatherings to attend, such as @Lambda_World, which is colocated with two other tech conferences in Málaga!🇪🇸🌞 So take your functional and non-functional friends and spend those few autumn days where it's still warm!
Call For Papers is open until the 31st of March 2026

In case you would run out of YouTube content to watch, two of my talks are now publicly available:
"What is Functional Programming?" from @LambdaDays
youtube.com/watch?v=pnZSff01…
and, somewhat related, but putting the above ideas into code, "A Tour of Ox 1.0: Direct-Style Concurrency and Resiliency" from @scaladays: youtube.com/watch?v=Gn0q5zsG…
Part of that last talk was live-releasing Ox 1.0, and if it wasn't for a vigilant audience member, I'd have forgotten to check if the release actually happened by the end of the talk ;) (it did).
🎥 New keynote video is live!
Romain Michon (Faust core dev & researcher at @Inria) shows how a functional language like Faust powers real-time sound processing — from musical instruments to immersive audio systems.
🎶 With live demos & cool embedded applications!

🚨If your Thursday’s dragging a bit, here’s something to shake it up ⚡
@odersky, the creator of Scala, gave an awesome keynote at Lambda Days, and the video’s now up! He dives into making capabilities safe and convenient, with some very cool Scala features along the way.

Many programmers would love to use "productivity languages" like @elmlang, but what about the business person who often makes the final decision?
How can we rethink our strategies such that authors, developers, and businesses grow stronger together? 🔄

#LambdaDays were a blast! A perfect balance between thought-provoking keynotes from researchers and industry-grounded talks covering various languages and ecosystems. And of course the hallway track! Glad to have met lots of interesting people. Going home with a lot of ideas.

Yesterday I finally presented my talk about Kyo's encoding of algebraic effects "Suspension: the magic behind composability" 🥳 If you want to understand how Kyo works under the hood, see the link in the reply 🪄
I had a blast at @LambdaDays! Meeting people from other programming communities, people I've interacted for years only online, other Brazilians, and even coworkers at the conference was a great experience. I'm definitely planning to return next year :)

Thank you @DevoxxPL & @LambdaDays! It's been very intense three days, with great hallway/functional/Java/AI tracks :) Hope to see you next year!
