Demystifying monads in Rust through property-based testing (sunshowers.io)
In programming pedagogy, monads have a place as a mystical object from the functional programming world that’s hard to understand and even harder to explain.

Build your own SQLite in Rust, Part 5: Evaluating queries (sylver.dev)
In the previous posts, we've explored the SQLite file format and built a simple SQL parser. It's time to put these pieces together and implement a query evaluator!

Linus Torvalds Would Reportedly Merge Rust Kernel Code over Maintainer Objection (phoronix.com)
The drama surrounding Rust code within the Linux kernel continues... Christoph Hellwig is the maintainer of the DMA mapping helpers and several other areas of the kernel has been an outspoken critic of Rust code or secondary programming languages within the Linux kernel kernel. Hellwig has been critical of Rust code for the Linux kernel and its long-term maintainability.

Greg K-H: "Writing new code in Rust is a win for all of us" (kernel.org)
As someone who has seen almost EVERY kernel bugfix and security issue for the past 15+ years (well hopefully all of them end up in the stable trees, we do miss some at times when maintainers/developers forget to mark them as bugfixes), and who sees EVERY kernel CVE issued, I think I can speak on this topic.

Blessed Rust Crates (blessed.rs)
The standard library in Rust is not "batteries included", excluding functionality like HTTP(S), JSON, timezones, random numbers, and async IO. The recommended crate directory is a hand-curated guide to the crates.io ecosystem, helping you choose which crates to use.

Parsing JSON in 500 lines of Rust (krish.gg)
Last semester at university, I took a course called "Syntax-Based Tools and Compilers". It focused on building a scanner, parser, compiler, and so on for a language called PL0. We used Python in the course, but I was really interested in learning Rust at the time.

TIL: Rust does not prevent memory leaks (ycombinator.com)
I'm not a Rust developer so I have no clues about what Rust does, how it does or why it is the way it is.<p>I had a short interaction on another thread and some user told that Rust does not prevent memory leaks.<p>People talk so much about Rust memory safety and how everything must be rewritten in Rust, but if Rust does not prevent memory leaks why are people so crazy about it?

Show HN: Cot: a Rust web framework for lazy developers (mackow.ski)
Cot was born out of frustration - the kind that every Rust developer feels when searching for a batteries-included, Django-like web framework that just handles the basics for you. While Rust is a really mature language, the web ecosystem is still sort of lacking. Let’s change that.

Rewriting essential Linux packages in Rust (lwn.net)
Most Linux systems depend on a suite of core utilities that the GNU Project started development on decades ago and are, of course, written in C. At FOSDEM 2025, Sylvestre Ledru made the case in his main stage talk that modern systems require safer, more maintainable tools.

Rust Is Eating JavaScript (2023) (leerob.com)
Rust is a fast, reliable, and memory-efficient programming language. It's been voted the most loved programming language six years in a row (survey). Created by Mozilla, it's now used at Facebook, Apple, Amazon, Microsoft, and Google for systems infrastructure, encryption, virtualization, and more low-level programming.

Solving the ABA Problem in Rust with Tagged Pointers (minikin.me)
Concurrent programming is challenging, especially when designing lock-free data structures. One subtle issue that can arise is the ABA problem, leading to unexpected behavior in compare-and-swap (CAS) operations. In this post, we’ll explore the ABA problem and how to solve it in Rust using idiomatic and efficient techniques.

The state of Rust trying to catch up with Ada [video] (fosdem.org)
Ada has held its own in the safety critical space for just over 4 decades. Over the last 10 years Rust has pushed into the same space with varying success. Among other features, most notably Rust is missing the powerful declarations and convenience of use of subtypes. In this talk I will go into the various features that make Ada so useful for ensuring the absence of bugs, and where Rust stands on each of these features.

Asahi Linux Lead Developer Hector Martin Steps Down (phoronix.com)
Following arguments on the Linux kernel mailing list the past few days over some Linux kernel maintainers being against the notion of Rust code in the mainline Linux kernel and trying to avoid it and very passionate views over the Linux kernel development process, Asahi Linux lead developer Hector Martin has removed himself from being an upstream maintainer of the ARM Apple code.
