Some things matter more than contributing to open-source software in your free time. A lot more. It’s trendy to ask for open-source work as evidence of your interest in tech and commitment to software development. Trendy and completely wrong. Companies should not demand open-source contributions from their employees, and beyond that, should learn to recognize that profit is not the most valuable thing in the world. People are...

Strings &strs and Vecs and slices (and Unicode) – oh, my! Notes This episode, I take a deep dive on strings in Rust, looking at the differences between String and &str, discussing Unicode a bit, and then expanding the discussion to think about how these types relate to the types they’re built on (like Vec)...

Just how good Rust is, and how you can learn it even if you’re busy. Notes Sometimes life goes crazy and I don’t have time to do all the technical writing required for a full episode, but I can’t get Rust off my mind, so I record an episode like this one. Where I talk a bit about how versatile Rust is and suggest some surprising ways you might be able to use it...

Reasoning about and using lifetimes in Rust (and why we need them) Notes Lifetimes are our way of reasoning about how long a given piece of data is available and safe to use in Rust. The reason we don't have the dangling pointer problem is that we do have lifetimes instead. They're not magic, they're just a bit of semantics and syntax that let us specify the rules for how long any given item lives, and how long references to data must be valid...

What it means to be an expression-oriented language, and how that works out in Rust. Notes Rust is an expression-oriented language. What does that mean, and how does it play out in Rust? We look at if and match blocks, discuss looping constructs, and examine functions, and then widen out to discuss how having an expression-oriented language can change the way we think about programming...

Type systems: strong vs. weak, dynamic vs. static, and degrees of expressivity...

Sean Griffin on type systems and hopes for Rust's future Notes ----- Chris chats with Sean Griffin about the tradeoffs between mental overhead and type safety, the expressiveness of different type systems, and some of the places where Rust currently falls down. ### Corrigenda Sean noted he could be wrong about `IEnumerable` not having a `Sum` method in C♯, and post-show research indicated that he was (it's possible it was added after he had stopped doing .NET work, of course)...

Sean Griffin on Rust, Diesel, and ORMs Notes Chris chats with Sean Griffin about his programming background and initial experience with Rust, Rust’s appeal, and what he’s doing with Diesel and some of his plans for a new web framework in Rust.

The value of a good community, and how you can help Rust today. Community is one of the most important parts of a programming language community, or indeed *any* technical community. In this episode, I talk a bit about what happens when you don't have a good community, how Rust's community has done well so far, and then how to keep building a good community and how to build good things *as* a community...
