When designing classes to overload operators, it is essential to choose whether to implement the operator as a member or as a regular non-member function.

Usage of placeholder modifier * in C/C++
C/C++中占位修饰符*的用法
In the process of solving problems, I came across this code snippet for formatting output: printf("%*s%s%*s\n",__________);
The required output format is: ________123456________//The underscores represent spaces
Ambiguity caused by incorrect use of macro definitions in C++
C++中错用宏定义造成的二义性
When writing code, the macro (#define) command is often used. Recently, I encountered two instances where macros were misused, so I’ll analyze them here.

As a C++ programmer, I have long been accustomed to using tools like GCC, but I must say that GCC’s error messages are terrible. Although there are error prompts, it often requires manual debugging to understand them… Now, the good news is here, the accuracy of Clang‘s messages is incomparably better than that of GCC.
Using Wolfram|Alpha to Evaluate Integrals
使用Wolfram|Alpha求积分
Actually, using WolframAlpha to compute integrals is quite overkill (but it’s also a strict requirement for laziness). Recently, I’ve been studying Wolfram Language and slowly discovering new ways to play with it.
Use Koding to manage static blogs online

Previously, I would complete articles on local and then publish them, having already set up a bunch of things like node.js, hexo, git, etc. on my own computer. So, it’s very convenient to use on my computer, but if I switch to another computer, it’s tragic; everything needs to be configured by myself, so I almost end up in a non-usable state whenever I change computers.
Reading "The Beauty of Mathematics"
读《数学之美》
I have had “The Beauty of Mathematics” for some time now, and as a book I’ve been reading during my leisure time, it has indeed piqued my interest a great deal. Since I don’t allocate much time to reading, averaging only one or two chapters a day, I finished all the chapters yesterday and was left wanting more.
Analyzing the Mathematical Principles in Cryptography
分析密码学中的数学原理
Recently, I’ve been intrigued by the mathematical models in computers discussed in “The Beauty of Mathematics” and the number theory from “What is Mathematics.” Today, I managed to suppress my laziness for a moment, and I’m going to analyze the mathematical models in cryptography!
Deploy Shadowsocks service on Linux
Linux部署Shadowsocks服务
These past few days, I reinstalled Linux and wanted to avoid using GUI for SS. The information online wasn’t very useful, so I experimented a bit.
