Idiomatic Monads in Rust
A pragmatic new design for high-level abstractions Monads (and, more generally, constructs known as “higher kinded types”) are a tool for high-level abstraction in programming languages1. Historically, there has been a lot of debate inside (and outside) the Rust community about whether monads would be a useful…

A deep dive into Multicore OCaml garbage collector
I recently gave a talk on the internals of multicore OCaml GC at Jane Street offices in NYC. The slides from the talk are available online . But I felt that the slides alone aren’t particularly edifying. This post is basically the slides from the talk annotated with notes.

Initialization in C++ is Seriously Bonkers
I was recently reminded of why I think it’s a bad idea to teach beginners C++. It’s a bad idea because it is an objective mess—albeit a beautiful, twisted, tragic, wondrous mess. Despite the current state of the community, this post is not a polemic against modern C++. This post is partly a follow-up on Simon Brand’s…

Running Rust on the Rumprun Unikernel
The Rust programming language has been able to run on bare-metal without the standard library for quite some while now. However, most Rust applications depend on the std crate, and therefore still need a full operating system to run.
