Originally published on tamiz.pro . The Silent Crisis: Undefined Behavior Across Language Boundaries Recent high-profile security incidents have exposed a growing concern in the software engineering world: undefined behavior (UB) is not just a C/C++ problem anymore. From Rust compilation bugs to JavaScript engine vulnerabilities, developers are witnessing how subtle language design choices can lead to catastrophic failures when code crosses language boundaries or interacts with low-level systems. These incidents aren't isolated — they represent a systemic issue affecting modern software stacks built on heterogeneous language ecosystems. Case Study: The Rust Memory Safety Myth Rust was built with the promise of memory safety without garbage collection. Yet, recent CVEs have revealed that undefined behavior in unsafe Rust blocks can compromise entire systems: The 2024 OpenSSL Rust Port Incident A critical vulnerability was discovered in a Rust port of OpenSSL where unsafe code blocks performed unchecked pointer arithmetic. While the safe Rust layer enforced bounds checking, the unsafe boundary passed raw pointers to the C layer without validation. // Vulnerable pattern discovered in the incident unsafe { let ptr = slice .as_mut_ptr (); // No bounds check - undefined if offset exceeds slice length let unsafe_slice = std :: slice :: from_raw_parts_mut ( ptr , len + offset ); } This wasn't caught by Rust's compiler because it explicitly allows unsafe operations. The UB only manifested during cross-language calls to the underlying C library. The WebAssembly Compilation Bug Another incident involved a Rust-to-Wasm compilation bug where the compiler optimized away what should have been defensive checks, assuming the guarantees of safe Rust would hold at runtime. When these assumptions broke at the Wasm boundary, attackers could trigger heap overflows. JavaScript's Hidden Undefined Behavior While JavaScript is often criticized for loose typing, its recent security incidents

Seven months after Elon Musk announced that Tesla Robotaxis in Austin were operating without human safety monitors onboard, the city's service appears to have finally gone fully driverless. Over the past two weeks, all 170 Tesla Robotaxi rides in Austin monitored by the crowdsourced Robotaxi Tracker were unsupervised, the site's creator, Ethan McKanna, told The […]
Is Amp Crash a guitar amp or a guitar pedal? Yes. Death By Audio's latest is, in fact, both. While it's in a guitar pedal enclosure, Amp Crash is actually a tiny 3-watt amp hooked up to a 2-inch speaker. You can even connect an external speaker if you want. This isn't a digital re-creation […]

I love writing in Markdown. What I don't love is opening a 200MB+ Electron app just to jot down a note. So I built Markify - a desktop Markdown editor that weighs in at under 10MB and still ships a real feature set. Why bother Obsidian is great, but it's heavy, and most of what I actually need day-to-day is simpler: open a file, write, preview, export, done. Every "lightweight" alternative I tried either wasn't actually light, or was missing basics like PDF export or a proper file explorer. So I built the tool I wanted. What's in it Open & save .md , .markdown , .mdx files with native dialogs Sidebar file explorer - browse a whole folder, expand subfolders on demand, just like VS Code Three view modes : Read, Edit, and Hybrid (live side-by-side preview) PDF export with embedded images and proper Unicode font handling Light/dark theme that follows your system in real time 4 languages out of the box: English, French, German, Spanish Native title bar per platform (real traffic lights on macOS, custom controls on Windows/Linux) The stack Angular 22 (with Signals) on the frontend, Rust on the backend, glued together with Tauri 2 . That combo is exactly why the app stays small - no bundled Chromium, no Node runtime shipped, just the OS's native webview. 82 unit tests (Vitest) keep the core services honest. Everything is open source, AGPL-3.0: github.com/Martzcode/Markify Markdown is basically AI's native language now Here's the other reason this project felt worth building right now: every LLM defaults to Markdown. Ask ChatGPT, Claude, or Copilot for anything structured and you get headers, bullet lists, code fences, bold text - Markdown, every time. It's become the de facto output format for AI because it's plain text, unambiguous to parse, and renders cleanly almost everywhere. That shift changes what a Markdown editor needs to be good at: Copy-pasting AI output should just work - no reformatting, no broken tables, no mangled code blocks Code block rendering with copy b
