I made one of my favorite pull requests ever on December 17, 2016:
rust-www/pulls/634: add npm to friends page
On any given day, the npm registry, a repository of packages primarily for JavaScript and Node.js, serves around 350,000,000 package downloads. The npm services team is small and this once little Node.js service, the lifeblood of the modern web development workflow, is now a huge set of microservices- and starting in late 2016, it’s no longer just Node.js- it’s running production Rust.
In this talk, I’ll tell the story of how I convinced my manager and team to give Rust a chance. Along the way, I’ll talk about the critical challenges that the npm registry services encounter on a daily basis, the patterns we’ve adopted to cope with the heavy operational load, and how they are well suited to be solved with Rust. I’ll also highlight the unique aspects of Rust that make it an pleasure to learn and teach, as well as how it is a strong technical candidate for replacing Node.js (hint: Tokio!).
At the end of the talk, you will have a keen understanding of what problems Rust is good at solving and feel motivated and empowered to start the conversation about bringing Rust into your own organization.

This is a guest lecture I gave at Two Sigma in November 2018 where I discussed the experience of using Rust for building larger, high-performance systems. In it, I cover what makes Rust an attractive option for such projects; Noria, the high-performance research database prototype I've built using Rust; an interesting concurrent data-structure we use in Noria; and how I've found Rust to work in that context.
The presentation slides are available at https://jon.tsp.io/slides/rust-twosigma/ .
You can read more about Noria at https://pdos.csail.mit.edu/noria .
Learn what makes the programming language Rust a unique technology, such as the memory safety guarantees that enable more people to write performant systems-level code. Hear about how Rust Editions evolve the language and the compiler without breaking existing code. See who’s trusting Rust for critical products today. Join us on Rust’s journey to the future.

Even as the climate is warming, there is so little we know about it today. Computational modeling is how climate scientists reconcile our understanding of climate with what we observe. Traditionally, these models would have been written in Fortran, but today’s climate emergency needs tools that are significantly easier to work with. Julia was built for this purpose and makes it easy for everybody focused on solving the problem to work together effectively. No more silos; we must now be part of an interconnected world.

Julia is a performance oriented language written from the ground-up to support numerical processing and parallelisation. The basic syntax of Julia resembles a cross between Matlab and Python, but offers performance which is comparable to compiled C-code. I will present an overview of the language with particular emphasis on where Python users may benefit in using it in their daily work.
Python users have long benefitted from the less verbose nature of Python, when compared with C and Fortran. However, Python was originally designed for scripting tasks, using dynamic types and widescale object orientation, neither of which features are necessarily beneficial when it comes to numerical computing. Thus, we have seen the widespread use of Python libraries for numerical computation (scipy, numpy, etc.).
Julia is a new language, developed at MIT, which attempts to learn from the experience of development of Python and similar languages. The main goals are to provide a non-verbose, performance oriented language written from the ground-up to support numerical processing and parallelisation. In its most basic syntax Julia resembles a cross between Matlab and Python, but via compilation through an intermediate level representation (llvm) it offers performance which is comparable to compiled C-code.
I am not going to argue that Julia is ready for primetime yet. However, it is definitely worth consideration by anyone currently resorting to cython or needing distributed access to large datasets.
I will present an outline/introduction to the language, including the main benefits and current weaknesses. Of particular interest to the audience may be the fact that Python libraries are importable and callable from within Julia, allowing a continuity of existing workflow but from a Julia-based host environment. My main focus will be for a numerically literate audience who are already contending with the technical limitations of Python and are curious about the new language in town.
