OCaml at LexiFi Nicolás Ojeda Bär ABSTRACT LexiFi is likely to have been the first real industrial user of OCaml, back when it was funded in 2000. In this talk, I will present some of the things we have learned along the way. Some of the ...

I Can See The Pixels: Designing Cross-Stitch Patterns in OCaml Mindy Preston (yomimono) ABSTRACT I was unsatisfied with existing cross-stitch pattern generating software, which was mostly structured like pixel-based paint programs. Those programs with support for very common operations like tiling borders were locked behind paywalls. I decided to write my own in OCaml, and I've been using it to design cross-stitch patterns since 2019. I'll talk a bit about the joy of making the Exact Right Tool, the anguish of abandoned experiments, and the ambiguous pleasure of monetizing art.

Frameworks: No, Libraries: Yes. Developing a product in OCaml from Scratch Malcolm Matalka (Terrateam) ABSTRACT Terrateam is an open source infrastructure management product written in OCaml. In order to stay lean and flexible, Terrateam has developed almost all of its own frameworks and tooling. With a small team, the Terrateam product punches well above its weight compared to its competition. This talk will cover the choice to develop their own frameworks, the good, the bad, and how OCaml has been instrumental in being able to achieve so much despite being a two person company.
