📰 図を描いて理解するRustの所有権 (👍 41)

🇬🇧 Visual guide to understanding Rust's ownership system using diagrams and chemistry analogies (H₂ + O₂ → H₂O) to explain memory safety concepts.
🇰🇷 다이어그램과 화학 반응 비유를 활용하여 Rust의 소유권 시스템과 메모리 안전성 개념을 시각적으로 설명합니다.

People often claim that memory-safe languages eliminate the class of memory bugs, but that is not true and can give less experienced devs a false sense of security.

You can violate borrow checker at runtime in Rust with zero unsafe blocks. You can have null-pointer dereference in C#. You can index out of bounds in Java.

The difference is that while C++ will crash at unspecified time with SIGSEGV (or not crash at all), memory-safe languages will either crash at a well-defined time in a well-defined way, or they will emit an exception you shall handle.

In the customers eyes, that might not even be a difference.

Soon on github: rilua - a Rust port of Lua 5.1. Key upgrades:

✅ Arena-based GC with gen. indices - no memory corruption
✅ Result-based errors - no longjmp/setjmp risks
✅ AST compilation - testable, optimizable pipeline
✅ Trait-based API - ergonomic embedding

Passes 19/23 PUC-Rio tests. Sacrifices some speed (0.9-2.2x) for memory safety & maintainability.

WhatsApp migrated 160,000 lines of C++ to Rust to eliminate memory-safety bugs. Here’s how compiler-level security changed its threat model.

"Rust is much more type safe than C is. And so if you have a void pointer, what does that mean in Rust? There's no translation for it. And that's how TrapC is fundamentally different because it actually remembers what that void pointer actually is."

Oh, joy! 🎉 Another ode to the almighty null pointer, where we learn that catching them is as easy as catching a cold in winter 🌨️. But wait, the "Billion Dollar Mistake" is just a misunderstood little rascal 🙄, because, really, who needs memory safety when you have "individualelement mindsets" to blame? 😂👨‍💻

Ah yes, the age-old quest for a Rust paradise without the meddling borrow checker—because clearly, who needs memory safety when you can live on the edge? 😂🔪 Why bother with the pesky details of secure coding when you can just throw caution to the wind and #YOLO your way through software development? 🙈💻

This week on #OpenSourceSecurity I chat with @djc and @ctz about #Rustls. A lot has happened with Rustls in the last few years (and there's a lot more to come). Writing a TLS implementation is incredibly complicated, even when you don't have to worry about memory safety

Rustls with Dirkjan and Joe

Josh talk to Dirkjan and Joe about Rustls (pronounced rustles), a Rust-based TLS library. Dirkjan and Joe are developers on Rustls. We talk about the history that got us to this point. The many many challenges in writing a TLS library (Rust or not). We also chat about some of what’s to come. Rustls has an OpenSSL compatibility layer which makes is a really interesting project.
