Introduction In the world of programming languages, Rust has long been labeled as “difficult to learn.” Many developers find themselves tormented by concepts like the borrow checker and lifetimes when they first encounter Rust. But is this “difficulty” label really fair? Today, we will not discuss how hard Rust is to learn, but rather take … Read more
Concurrency refers to the ability of a program to handle multiple tasks simultaneously. In Python, the two core methods for achieving concurrency are multithreading and multiprocessing. Although both can execute tasks “in parallel”, their underlying implementations and applicable scenarios are quite different, with the key difference being the memory space isolation between processes and threads.Multithreading … Read more
A Trio of Concurrency in Rust:<span>Join</span>、<span>Arc<Mutex></span> and <span>mpsc</span> Channel Synchronization in Practice Concurrency is one of Rust’s core advantages, but handling shared state and thread communication has always been a challenge in programming. Rust, with its ownership system and unique synchronization primitives, makes multithreaded programming safe and efficient, completely eliminating common issues like data races … Read more

Core Skills in C Programming These are the foundational skills you must master: Pointers and Memory Management Pointer arithmetic, relationship between pointers and arrays Multi-level pointers, pointers to functions Memory layout: stack, heap, BSS, data segment Structures and Unions Memory alignment, padding Bit fields Nested structures and flexible array members Preprocessor Techniques Macros, conditional … Read more
Introduction When using<span><span>HttpWebRequest</span></span> to initiate HTTP requests in C#, you can improve concurrency and performance in the following ways: 1. ServicePointManager Settings <span><span>ServicePointManager</span></span> is a static class that provides properties and methods for managing HTTP connections. To enhance concurrent performance, you need to adjust the following key properties: DefaultConnectionLimit: By default, the .NET Framework’s<span><span>ServicePointManager</span></span> limits … Read more
The most frustrating part of scripting is getting “stuck on the third line”: incorrect file paths, missing dependencies, or logs without color. Pydoer acts like an on-demand operations partner, turning the “download-install-start-stop-clean” pipeline into 5 Python statements. Students in the lab and programmers in coffee corners can run the entire process with a single command. … Read more
Boost.Fiber: A Lightweight User-Space Thread Framework in C++ In modern multitasking programming, threads are the fundamental units for achieving concurrency and parallel computation. However, the cost of context switching between threads is relatively high, especially at the operating system level. To provide a more lightweight concurrency solution, the Boost.Fiber library was created. What is Boost.Fiber? … Read more
Optimizing Linux System Configuration for One Million Concurrent Connections When building high-performance servers, the ability to handle high concurrency is crucial. To achieve one million concurrent connections on a Linux system, it is essential to adjust the following core parameter configurations. Shell Resource Configuration Check and adjust the shell resource limits using <span>ulimit -a</span>, as … Read more
In the previous chapters, we learned how to explicitly create and manage threads using <span>std::thread</span>. This is a powerful and straightforward method, but it can sometimes feel cumbersome. Often, we just want to execute a task asynchronously and retrieve its result at some point in the future without manually handling the tedious details of thread … Read more
It’s time to supplement some knowledge about <span>asyncio</span>… The following content is extracted from the video by <span>gemini-2.5-pro</span> corresponding to <span>Corey Schafer</span>‘s video on YTB, provided as a backup for reference, and the original video is recommended for learning. This is the second part; the first part can be found in the Python asyncio Tutorial: … Read more
