    Learning C++ in College and Why I’m Bringing It Home to My Kids

    A college student learning C++ shares their motivation for studying the language—not for trends, but for foundational skills like logic, memory management, and problem-solving. They plan to teach these fundamentals to their children, emphasizing understanding systems over consuming tools, and using AI as an assistant rather than a crutch. The approach focuses on building blocks: step-by-step logic, input/output, variables, loops, and debugging with patience.

    C++ and Rust

    The Rust vs C++ debate has intensified, with Rust gaining adoption for its memory safety without performance costs. However, complete replacement may be unnecessary. Major projects like Chromium demonstrate that combining both languages strategically works well, using Rust for memory-critical components while maintaining C++ for other parts. Game engines and established codebases show C++ isn't easily replaceable. A pragmatic approach suggests both languages have distinct strengths and can coexist rather than one completely replacing the other.

    I got paid minimum wage to solve an impossible problem.

    A computer science student turned a supermarket floor sweeping job into an optimization problem using simulated annealing and the traveling salesman problem. The initial solution minimized distance but created an impractical path with excessive turns. Adding a turn penalty to the cost function produced a more realistic, human-friendly route. This experiment illustrates how optimizing for easily measurable metrics (distance, engagement, profit) instead of actual goals (usability, wellbeing, sustainability) leads to technically correct but practically useless or harmful outcomes in algorithms, social media, AI, and business.

    beginner-jhj/mini_browser

    A high school student built a functional browser engine from scratch in C++ over 8 weeks to understand how browsers work internally. The project implements HTML/CSS parsing, DOM tree construction, layout calculation, and rendering using Qt6. It covers the complete browser rendering pipeline: tokenization, DOM construction, style calculation (CSSOM), layout computation, and painting. The implementation supports core CSS properties, image loading with caching, navigation with history, and handles both block and inline layouts. Beyond technical achievements, the author emphasizes lessons in systematic debugging, persistence, pragmatism over perfection, and the importance of asking "why" when learning.

    Eliminate them all

    A Microsoft distinguished engineer posted on LinkedIn about eliminating all C/C++ code from Microsoft by 2030, claiming one engineer could rewrite 1 million lines per month using AI and algorithms. The post sparked controversy when he later clarified Windows wasn't included in this plan, despite the original statement saying 'every line.' The commentary criticizes the feasibility of such rapid rewrites, noting C++ and Rust solve problems differently, and questions Microsoft's ability to maintain Windows stability given recent update issues.
