Building Tools for Traders with Ian Henry
Ian Henry, Ron Minsky, Mark Mandelbaum, Mark Mirchandani, David Eastman, Brian Dorsey
Ian Henry, a Jane Street engineer who transitioned from general web development to options trading tools, leverages the firm's custom OCaml ecosystem to build high-density interfaces that eliminate mouse usage and manage complex volatility surfaces. His recent work includes creating Bauble, a live 3D graphics environment in the Janet language that demonstrates how side projects using image-based state serialization and novel macro systems can rapidly inform internal production tooling. Through this process, Henry illustrates how Jane Street bridges the gap between low-latency exchange architecture and expert user needs by prioritizing type safety, extreme information density, and a parallel software universe free from standard web protocols.

What is an Operating System? with Anil Madhavapeddy
Anil Madhavapeddy, Ron Minsky, Mark Mandelbaum, Mark Blyther
Mirage OS is a pure OCaml unikernel framework that compiles applications into minimal, single-purpose binaries by linking only essential drivers and protocol stacks directly to the kernel. Since its origins as a Cambridge research project to verify high-level language performance, the system has achieved significant industrial adoption, powering Docker for Mac and Windows, Tezos blockchain nodes, and energy-efficient solar sensor networks. By utilizing a library operating system model and advanced features like the LDRF memory model, Mirage delivers enhanced security through a reduced attack surface while enabling scalable multi-core execution in upcoming language releases.
