Why Use Structured Errors in Rust Applications? TL;DR I prefer thiserror enums over anyhow , even for application code that simply propagates errors. Custom error types require additional effort, but make the code easier to reason about and maintain down the road. “Using thiserror for libraries and anyhow for applications” In 2025, this is the conventional error handling practice in the Rust community. Let’s quickly recap the main ideas: Libraries should expose error types that provide as mu

The update in question, KB5058405, was automatically rolled out to devices running Windows 11 versions 23H2 and 22H2. Instead of simply improving security, it has triggered a critical error for a subset of users.

Type inference has a reputation for causing unhelpful error messages from the compiler when there is a type error. For example, here’s a typical comment: However, things don’t have to be this way. Type inference’s bad reputation is due to design decisions in existing languages that sacrifice good error messages in exchange for other goals. There is nothing inherent to type inference that prevents you from offering good error messages. I recently released PolySubML, a programming language combi

Using unwrap() in Rust is Okay One day before Rust 1.0 was released, I published a blog post covering the fundamentals of error handling. A particularly important but small section buried in the middle of the article is named “unwrapping isn’t evil”. That section briefly described that, broadly speaking, using unwrap() is okay if it’s in test/example code or when panicking indicates a bug. I generally still hold that belief today. That belief is put into practice in Rust’s standard library a

LLM-powered agents are beginning to look a lot like tireless junior developers. Hand them an API along with the docs and they’ll diligently read the reference, issue a request, parse the error, adjust parameters, and try again and again—on loop—until something works. Frameworks like LangChain and OpenAI function-calling helpers, as well as agents like Cursor, Claude Code, OpenAI Codex, and Codename Goose, make that cycle even easier to wire up and follow. But raw persistence of an agent isn’t

I recently attended RustWeek (which was totally awesome) and the talks by Alex Crichton (on the history of Rust) and Pietro Albini (on the importance of error messages) inspired me to do a little archaeology into the way Rust compiler messages have evolved over time.

I noticed that handling the None variant of Option without falling back on unwrap() is a common papercut in Rust. More specifically, the problem arises when you want to return early from a function that returns a Result if you encounter None . It has been discussed a million times already, but, surprisingly, not even the Rust book mentions my favorite approach to handling that, and many forum posts are outdated. With a bit of practice, robust handling of None can become as easy as unwrap() , b

Learning, to a computer, is just turning bad guesses into better ones. In this post, we’ll see how that starts with a straight line: how linear regression makes the first guess, and gradient descent keeps improving it. Let's start with something familiar: house prices. Bigger houses tend to cost more; smaller ones, less. It's the kind of pattern you can almost see without thinking: more space, more money. When we plot it, the shape is clear: a loose upward slope, with some noise but a definite
