Fuzz testing is incredibly useful: it has caught many a bug during the development of NTP packet parsing and gzip/bzip2 (de)compression.

But I've always been unsatisfied with the fuzzer being a black box. When it runs for hours and reports no issues, what do we actually learn from that? In ntpd-rs we've previously had a bug fly under the radar because the fuzzer just did not reach a large chunk of code. So, does my fuzzer actually exercise the code paths that I think it should?

We've been writing how-tos about using Rust in existing C, Python, and C++ projects, but this article shows you an in-production example of Rust interoperability: Recently I worked on exposing the TSP Rust API to Python and NodeJS users.

Mix in Rust with C++

This article will help you to slowly introduce some Rust into your C++ project. We'll familiarize ourselves with the tooling and go through some examples.

Can't wait to learn how to call C code from your Rust project after reading my previous posts about Rust interop in general and calling Rust from C? Good! If you haven't read those yet, please do, because I'm going to assume you have in this article. We've seen the basics of Rust's FFI, and have experimented with calling Rust from C. Going the other way around, you'll walk into much the same challenges.

The other day I came across Diplomat, an opinionated tool that makes a lot of choices for you. If you've read my previous post in this series, you'll have seen that that can be quite valuable. If you haven't read the previous article yet, do so before continuing to read this one, as it'll help you appreciate the concepts in this post, and it introduces the example as well.

Mix in Rust with C

So, you've just read my previous post on Rust interoperability in general, and now you're curious about how to actually apply the concepts to your situation. You've come to the right place, because in this post and the two that follow, I'll demonstrate how to make Rust and C talk to each other.

Mix in Rust

What does it actually mean to introduce Rust in an existing project, and having it communicate with other languages in the code base? This article launches a series of blog posts that provide guidance for introducing Rust into your code base step by step.

Our tagline reads “Software must become safer”, and for good reason; We feel very strongly about this. But it does lead to the obvious and fair question: “What exactly do you do to ensure that the software your teams produce is safe and secure?”

In February of 2024, I was invited by Matthias Endler of Corrode to join him on his podcast Rust in Production. We discussed how Tweede golf uses Rust in production, to ensure the safety and security of critical infrastructure software.

If one person at Tweede golf is a Rustacean, it’s definitely Wouter. Whether it’s about web, embedded, or even games: he tried it. And probably not just tried it, but prototyped, created, documented, presented, and nailed it. Just take a look at Wouter’s GitHub page[1]. He’s also engaged in the Rust community as an organizer of RustFest, member of the Dutch Rust foundation, and as maintainer of several open-source crates. He believes that Rust is well on its way to perfection.

Functional Rust? (4/5)

Lars started at Tweede golf about a year ago. We lured him in with the prospect of working on a cool embedded project in Rust. Since then he clocked a lot of Rust hours on it and on a research project we are running. Still, he manages to astound us with critical notes on Rust. Rightly so? Let's just say interviewing a functional programming purist like Lars gives us a lot of new perspectives around Rust.

Rust wide web (2/5)

Ruben has experience with a lot (and I mean a lot) of programming languages. When I asked which ones, he could name 21 off the top of his head. He loves experimenting with them, seeing what each can and can’t do. What makes a language unique? What can one language do better than the other? Why was Ruben the one to first evangelize Rust within Tweede golf? Let’s ask him!

At Tweede golf, we’ve been visiting meetups and conferences throughout the years. As we have high hopes for Rust, and a strong personal adoration for the language, we decided on hosting our own Rust meetup and starting a Rust Nijmegen group.

We often get the question how productive working with Rust is. "We know that it is awesome, but isn't it hard to learn? Don’t you struggle with the borrow checker?". Well, we put it to the test in Google's Hash Code 2019 programming competition.

We all want our 3D visualisations to be as real as possible. A basic premise seems to be that they adhere to the laws of physics. No small feat! Or is it?

We decided to give it a go during a two-day programming contest. Our team's idea was to develop a web-based game where the user cycles around and has to avoid crashing into cars. To create the game, we needed a physics engine.
