Launch time!

ScalaIO 2025's starting! With a few minutes late 🤫

ScalaIO's tomorrow! If you cannot attend in person, we've opened streaming tickets available on the website 👉 scala.io This will give you access to live stream and a replay link, in case you're not in the same TZ 🤗

ScalaIO's around the corner! We'll have a community party on Friday at 7pm, come have a drink (and food!) with us 😊 (more information will follow) See you soon!

OMG wow! Catalytic compilation in @ApacheSpark - this will be another cracker definitely. So, a double-cracker definitely, in Data Engineering category - At #ScalaIO Paris 2025 as I’m diving into Compile-time data contracts which fuels Data pipelines, don’t make pipelines unbreakable - they make breakage predictable. And, stoked to see Catalytic compilation - transforming code generation with macro superpowers. Come geek out with me - scala.io/sessions #scala #data #dataengineering @ScalaIO_FR

📢Last batch ! Balanced sampling as a tool for useful PBT random tree generation (Jim Newton) -> get more representative outputs for your ASTs Running LLMs Locally with Scala: From APIs to Local Inference (Sören Dreano) -> privacy, speed and type safety to build AI-powered apps

Penultimate batch ! API-First or Scala-First? Generating APIs with ZIO-HTTP (@wiemzin) bridge the gap between API design for stakeholders and developers Catalytic Compilation : A modern take on safe spark (@dmatheson8) unleash Scala 3 features to easily build safer pipelines

Can we have the Standard Library for Macros? (@MateuszKubuszok) makes simple things simple, and hard things (at least) possible 🚀 Event Sourcing is just a foldLeft on Events and a decide function! Or is it? (@squircles_io) master of immutability but UPDATE db all day long ? 👀

I am very happy to announce that will be speaking at Scala.io in Paris on 17 October! This will be my first conference talk since 2019, and I'm going to try to make it the best ever! I will introduce soundness.dev to the world: a tour de force of all the wonderful things you can do with Scala 3. I will show you an exciting, optimistic and realistic future for Scala. I will show you how to build CLI and web applications with code that's as easier to read than Python or JavaScript, but just as safe as Haskell. Thank you to the conference team for giving me this opportunity. Scala.io has a special place in my heart: it's always been a delightful, independent and friendly event, and I'm excited to be coming back to Paris! If you want to see the pinnacle of coding elegance, then please come along!
