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.

Mix in Rust with Python: PyO3
In this article, we'll dive into combining Rust with Python. Specifically, this post covers calling modules written in Rust from Python scripts.

Mix in C with Rust: A taste of C in your Rust
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.

Want more Rust? Break the cycle!
Let's be frank: Rust is a cool language, but there's not a chance I'm introducing it in my company if I can't get any engineers for it. We'll stick with technologies with a much healthier job market.

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.

Teach-rs: Rust 101 evolved
At the end of 2022, we announced the creation of Rust 101, a university course that introduces students of computer science to Rust. Initially, the course was created for the Faculty of Informatics and Information Technologies at STU Bratislava (FIIT), but from the start we've wanted to create an open-source, modular and reusable set of teaching resources. Having now achieved that milestone, it is time for a new announcement: Rust 101 has evolved to teach-rs.

Rust 101's first run at STU Bratislava
When we first introduced Rust 101 to you on our website, preparations for its first run where in full swing. The action started in February 2023; 20 students of the Faculty of Informatics and Information Technologies of the Slovak University of Technology in Bratislava followed 9 lectures and 9 tutorials, and worked on their own rust project to round off the course. The course was completed in May.
A while ago, in 2020, I wrote a blog post similar to this one. Sure, it has a bit of a clickbait-y title, but it couldn't be more accurate. At the time I was full of amazement about the way Rust tackles embedded software development. I forsaw great things for Rust's future, even though Rust and its ecosystem were yet not quite mature. We're 3 years further down the road right now, which is like 300 Rust years as Rust is progressing fast. About time for an update!

Rust 101: an open-source university course
In 2009 Rust was a new language. In 2022 that isn't true anymore. Nor does Rust have anything to prove. It's made it to the Linux Kernel, and Microsoft have dubbed it "the Industry’s Best Chance at Safe Systems Programming".

Long range networking with LoRa: an overview
Welcome to the age of communication. It's 2021 and technology has come a long way. People, large machines and small devices communicate more intensively than ever before, and many technologies to enable them to do so have been developed. Some of those technologies use physical pathways like fibreglass to reach their receivers, others use radio signals to send messages. It's these wireless communication technologies that spark the imagination the most.

Why Rust is a great fit for embedded software
Rust is nice for a lot of things. At Tweede golf we've been using the language primarily for high-performance web applications. But that's not all Rust can do. Rust can be used to write embedded applications as well.

The persistent microservice
The point of setting up a miniservice architecture is to enable horizontal scaling, improve reusability and to speed up development by separating each domain into an independent application. Miniservices depending on a database pose a number of challenges. We'll explore a couple of them.

Transitioning to a miniservice architecture
Imagine this: you have made the wise choice of taking the monolith-first approach, setting up an application. You have read my previous article about the pros and cons of miniservices. And now, the time has come to start the transition to a miniservice architecture. How do you go about that?

From monolith to miniservices (indeed, not microservices)
Tweede golf has built quite a few big web applications over the last ten years. One of our specialties being the development of Symfony applications, some of these applications have become massive, with a lot of separate functionality baked into a single monolith. For now, this situation is being contained as we've been strict about minimizing technical debt. In practice, however, it's extremely hard to completely avoid accumulation of technical debt, which is one of the reasons we have started looking into introducing microservice architectures into our projects.

Implementing Lempel-Ziv Jaccard Distance (LZJD) in Rust
One of our clients helps companies in becoming GDPR-compliant. A goal is to recognize sensitive pieces of user data in a big pile of registrations, receipts, emails, and transcripts, and mark them to be checked out later. As more and more data is collected by companies, finding and eliminating sensitive data becomes harder and harder, to the point where it is no longer possible for mere human employees to keep up without assistance.
