Community PicksΒ·2yMemory Safety in C++ vs Rust vs Zig
The post compares C++, Rust, and Zig in terms of memory safety. C++ offers freedom but can lead to unsafe memory practices; Circle C++ provides stricter safety features while maintaining compatibility with existing codebases. Rust ensures exceptional memory safety with a strict compiler and concepts like the borrow checker. Zig strikes a balance with reasonable memory safety and ease of use, making it simpler to integrate into existing projects. Key focus areas include lifetime safety, type safety, and runtime safety, highlighting how each language handles these aspects differently.

Barry's C++ BlogΒ·2yCode Generation in Rust vs C++26
The post compares how Rust and the upcoming C++26 handle code generation and reflection. While C++26 is working on integrating reflection capabilities, Rust excels in code generation using declarative and procedural macros. Key examples include pretty-printing structs and JSON serialization, highlighting the differences in syntax and library design between the two languages. The discussion emphasizes how Rust's derive macros inject necessary implementations automatically, whereas C++ uses introspection to achieve similar results with less boilerplate code.
LobstersΒ·2yC++ Design Patterns For Low-Latency Applications
Performance optimizations remain crucial in applications like high-frequency trading (HFT), where low latency is essential. This post discusses a preprint article from Imperial College London focusing on design patterns in C++ for low-latency applications. The optimizations include common practices like prewarming CPU caches and advanced techniques like hotpath versus coldpath separation. Benchmarks using Google Benchmark demonstrate the effectiveness of these patterns, and the detailed implementations are available on GitHub.
ThePrimeTimeΒ·2yCreator Of C++ On How Long To Learn A Language | Prime Reacts
Learning a language like C++ can vary significantly based on prior programming experience. Experienced programmers might pick up the basics in days or weeks through resources like 'A Tour of C++,' but reaching a professional level can take months or years. Understanding complex code written by others can be particularly challenging due to heavy use of macros and templates. The post also highlights that merely knowing the syntax doesn't equate to mastering the language's intended usage.
Game DevelopersΒ·1yMath in programming...
The author shares their newfound realization about the importance of math in programming, particularly in the context of game development. They provide a C++ code snippet demonstrating the use of mathematics to animate a platform in a game by adjusting its position using trigonometric functions.
Low Level Game DevΒ·2yI made my own shadertoy in C++
A developer shares their experience of creating a custom Shader toy in C++, complete with features like sliders, custom textures, color pickers, and a full 3D pipeline. The project aims to provide functionalities missing from Shader toy, such as the ability to modify uniforms and write optional vertex shaders. The developer also discusses tackling various challenges, such as detecting shader uniforms and making the project Shader toy-compatible, ultimately planning to expand the tool further with more features.
P99 ConfΒ·2yRust vs. Zig β and C++ and Mojo β for Systems Programming
At P99 CONF, a debate between Jarred Sumner, Pekka Enberg, and Glauber Costa on ThePrimeagen's Twitch stream explored the benefits and drawbacks of Rust and Zig for systems programming. Key points included Rust's memory safety and robust ecosystem, and Zig's low-level control and better interoperability with C. They also touched on Mojo's potential, particularly for machine learning, and agreed that both Rust and Zig offer significant advantages over older versions of C++.
Marius BancilaΒ·2yWhatβs new in C++26 (part 1)
C++26 introduces several new language and library features, such as specifying a reason for deleting a function, using placeholder variables with no names, and allowing structured binding declarations as conditions.
