Abstracts & bios:

"Scala 3 support in IntelliJ Scala Plugin", Maciej Gorywoda

If you follow releases of IntelliJ IDEA and the Scala Plugin, you might have noticed that “Scala 3 support” is the main topic of almost every blog post with release notes. Every four months, give or take, the Scala Plugin team delivers better handling for established Scala 3 features and new developments, supporting those that landed only recently or are still in the experimental phase. In this talk, we will try out a few of them, such as enums, indentation syntax, named tuples, and transparent inline methods.

I’m a Product Marketing Manager in the IntelliJ Scala team at JetBrains. I graduated from Warsaw University of Technology in 2005 with an MSc in artificial neural networks. I worked as a video game AI expert, a web tools and Android developer, a Scala software developer, and since two years ago a person who writes and talks publicly about features of IntelliJ Idea with the Scala Plugin. In 2024, I became a Scala Ambassador. In my free time, I train martial arts, read lots of history books, and run a YouTube channel.

"Easier Scala Builds with the Mill Build Tool", Haoyi Li

Mill is a Scala build tool that improves upon every aspect of the venerable SBT toolchain: more performant, easier to understand, and scalable to larger codebases. Most importantly, Mill makes build configuration easy: easier to write, easier to navigate, and easier to understand. This talk will explore how Mill works, demonstrate its advantages over SBT in a live-coding setting, and dive into the novel techniques that a modern build tool uses to improve upon older build tools of years and decades past.

Li Haoyi graduated from MIT with a degree in Computer Science and Engineering, since then has built core infrastructure for high-growth companies like Dropbox and Databricks, and has been a major contributor to the open source community. Author of the "com-lihaoyi" suite of OSS Scala projects, these projects have over 10,000 stars on Github, and are downloaded over 20,000,000 times a month. Haoyi has deep experience in the JVM and has professionally built distributed backend systems, programming languages, high-performance web applications, and much more.
