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, Haoyi has deep experience in the JVM and has used Scala to professionally build distributed backend systems, programming languages, high-performance web applications, and much more.
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.

The Functional World conference aims to improve learning & knowledge sharing by meeting with other people passionate about functional programming. On Functional World, you can find topics related to all functional languages Scala, Clojure or Haskell to name a few.
Our event on the meetup platform has already gained over 1300 members. You can see the articles, access videos, and get information about members. These numbers keep growing and allow the event to develop and expand its horizons.

If you’re interested in upcoming Scalac’s Functional World events, you should also check out our Meetup page!
The first of the event created by Scalac was the Tricity Scala User Group (TSUG), which allowed for the support and association of local societies. However, we wanted to broaden the horizons beyond the Scala theme. Therefore, our team took up topics related to functional programming and created the Functional Tricity Meetup.
During the pandemic, Scalac decided to broadcast the event online and changed its name to Functional World and involve programmers from different parts of the globe.
