In C++, template specialization allows us to provide specialized implementations for specific type parameters in templates. When the compiler encounters a specific type, it prioritizes the specialized version over the generic template. For example, for a generic template function that can compare the sizes of any two types of data, when it comes to comparing … Read more
The comprehensive online examination platform for universities, YunKaoKu, is continuously pursuing performance optimization to provide candidates with a more comfortable online examination experience. This morning, the YunKaoKu platform achieved HTTP/2.0 protocol transmission, replacing the traditional, outdated, and inefficient HTTP/1.1 protocol, resulting in page load times of less than 0.4 seconds. The core differences between … Read more
Before the advent of the C++11 standard, developers faced a tricky problem: how to store, pass, and invoke different types of callable entities in a unified manner? Ordinary function pointers cannot adapt to member functions (which require binding the <span><span>this</span></span> pointer), the type closure of functors (function objects) prevents cross-type generality, and the implementation of … Read more
Have you encountered such development pain points: the internal network environment cannot access external APIs and needs to be debugged through a proxy? Or do you need to monitor the HTTP request traffic of team applications? Recently, many developers in the .NET technology group have been discussing a common question: “How to quickly implement a … Read more
In-Depth Analysis of Linux Zero-Copy Technology Overview Zero-copy is an efficient data transfer technology designed to reduce CPU involvement in data copying operations, thereby improving system performance and reducing CPU load. In the Linux kernel, zero-copy technology is implemented through various mechanisms, including <span>sendfile()</span>, <span>splice()</span>, <span>copy_file_range()</span>, <span>mmap()</span>, and DMA (Direct Memory Access). Working Principle Traditional … Read more
Today, I want to share a small tool I recently discovered — <span>ccusage</span>. Although the project is small, its functionality is indeed impressive! I tried it out, and it **directly analyzed tens of thousands of lines of C code in a project, producing results in seconds, and the performance skyrocketed!** It is fantastic for investigating … Read more
