With so many programming languages like Python, C++, and C, how should I choose? There is no “best” language, only the “most suitable” one. The choice depends on what you want to do (Web, App, data analysis, system development?), the difficulty of learning, community resources, and personal interest. Beginners should prioritize languages that are syntax-friendly, … Read more
In the era of Industry 4.0, Industrial Internet of Things (IIoT) technology has gradually become the core of the manufacturing industry. By connecting devices to the network, interconnectivity between devices can be achieved, which improves production efficiency, optimizes production processes, and reduces production costs. To efficiently monitor and manage IIoT devices, developing a high-performance monitoring … Read more
1. Background 1. Storytelling Previously, I shared an article about <span>unmanaged memory leaks caused by C# calling C code</span>. This was a deliberately induced positive leak. In this article, we will explore the root cause of the leak from a reverse perspective. This issue is relatively easy to handle on Windows, as many people know … Read more
In this article, we will create an IIS hosted handler using C# to handle some special requests for our website. This hosted handler can perform various functions, such as preventing hotlinking and downloading of audio, video, and image resources on our site, as well as providing special services like webSocket services. We can write a … Read more
Introduction In modern game development, the performance of the game physics engine is crucial for creating a realistic gaming experience. From collision detection to complex rigid body motion simulation, the physics engine needs to handle a large number of mathematical calculations. The traditional Single Instruction Single Data (SISD) processing method gradually reveals performance bottlenecks when … Read more
Flurl is a modern URL builder.Building Flurl.Url Implicitly create Flurl.Url objects using string extension methods using Flurl;var url = "https://some-api.com" .AppendPathSegment("endpoint") .SetQueryParams(new { api_key = _config.GetValue<string>("MyApiKey"), max_results = 20, q = "I'll get encoded!" }) .SetFragment("after-hash");// result:// https://some-api.com/endpoint?api_key=xxx&max_results=20&q=I%27ll%20get%20encoded%21#after-hash 2. Create a Url object explicitly; all string extension methods can also be used with System.Uri var … Read more
