ai.bythebay.io Nov 2025, Oakland, full-stack AI conference The Chunk data structure powers the fs2 streaming library. In this talk, we’ll look at the design of Chunk and in particular, how design constraints guided its evolution.Michael has been using Scala since 2009, when he was convinced to give it a try by listening to Dick Wall and the Java Posse. He introduced Scala at Comcast and has written a number of open source functional programming libraries since then, including scodec, simulacrum, and ip4s. He’s also the lead maintainer of FS2, a pretty neat functional streaming library, and contributes heavily to the Typelevel ecosystem.
