Article Steve Klabnik · 1y Is Rust faster than C? Comparing Rust and C performance is complex because 'all things being the same' is difficult to define. While both languages can achieve similar performance through inline assembly and compiler optimizations, they differ in default behaviors like struct field ordering, bounds checking, and safety guarantees. Rust's compile-time safety checks may lead developers to write different code patterns than in C, affecting runtime performance. Social factors also play a role, as developers may be more willing to write performance-oriented code in Rust due to its safety guarantees. Fundamentally, there's no inherent reason Rust cannot match C's performance capabilities. 75 4 12. 13 [](/posts/my-game-development-journey-finding-my-path-nk2vvtnyu "My Game Development Journey: Finding My Path") Article Game Developers · 1y My Game Development Journey: Finding My Path The author shares their journey from studying economics to pursuing game development, highlighting challenges such as tutorial dependency and finding a better approach through hands-on experience.

While Rust offers memory safety advantages and is gaining adoption in new projects by major tech companies, the vast existing C codebase and lack of motivation to rewrite stable systems means C will persist. Rust may eventually inherit C's role in systems programming, but both languages will coexist, with C remaining relevant for understanding machine fundamentals and Rust providing safer alternatives for new development. 73 24 14. 15 [](/posts/the-tor-project-is-now-rewritten-in-rust-instead-of-c-qctr5ukre "The Tor Project is Now Rewritten in Rust Instead of C") Article It's Foss · 44w The Tor Project is Now Rewritten in Rust Instead of C Arti 1.8.0, the Rust rewrite of Tor, introduces circuit timeout improvements that replace predictable timing patterns with randomized intervals to reduce fingerprinting risks.

The rewrite addresses memory safety vulnerabilities inherent in the original C codebase, including buffer overflows and use-after-free bugs. 69 3 15. 16 [](/posts/why-were-90s-programmers-so-legendary--8bkczpwfh "Why were 90s programmers so legendary?") Video bigboxSWE · 50w Why were 90s programmers so legendary? Explores why 1990s programmers like John Carmack, Linus Torvalds, and Richard Stallman became legendary figures. The era's severe hardware constraints—limited RAM, slow processors, and scarce resources—forced developers to write highly optimized code and build tools from scratch. Without modern conveniences like package managers, AI assistants, or abundant tutorials, programmers had to master low-level optimization techniques, including manual memory management and assembly code. While the problems were simpler in scope compared to today's distributed systems, the technical challenges were significantly harder, creating a generation of developers with deep systems knowledge. 69 20 16. 17 [](/posts/why-is-sqlite-coded-in-c-953jfnju9 "Why Is SQLite Coded In C") Article Hacker News · 1y Why Is SQLite Coded In C SQLite remains implemented in C because it provides optimal performance, universal compatibility across platforms and languages, minimal runtime dependencies, and stability. C enables SQLite to be called from any programming language, requires only basic standard library functions, and avoids the complexity of modern language runtimes. While safe languages like Rust are acknowledged as potential future options, the SQLite team prioritizes mature, well-understood languages and notes that recoding would likely introduce more bugs than it would fix. The article addresses common questions about why SQLite wasn't built with object-oriented languages or modern safe alternatives. 70 21 17. 18 [](/posts/in-defense-of-c--ajukwsrbp "In Defense of C++") Article DEV · 1y In Defense of C++ C++ remains a powerful and relevant programming language despite common criticisms about complexity, safety, and being outdated. The language's perceived complexity can be managed by starting simple and adding advanced features only when needed. Modern C++ standards (C++20, C++23) continue to evolve with new features like modules and coroutines. While memory safety concerns are valid, they can be addressed through smart pointers and proper practices. C++ continues to power major systems from browsers to game engines, and rewrites to other languages often succeed due to architectural improvements rather than just language choice. 71 8 18. 19 [](/posts/qgis-qgis-qgis-is-a-free-open-source-cross-platform-lin-win-mac-geographical-information-system-2sim61rdr "qgis/QGIS: QGIS is a free, open source, cross platform (lin/win/mac) geographical information system (GIS)") Article Hacker News · 1y qgis/QGIS: QGIS is a free, open source, cross platform (lin/win/mac) geographical information system (GIS) QGIS is a free, open-source geographical information system that runs on multiple platforms.
