Summary of High-Quality C++ Programming Guidelines

by

The core goal of high-quality C++ programming is to write maintainable, scalable, efficient, and safe code. Below are practical high-quality programming guidelines covering key dimensions such as coding standards, design principles, performance optimization, and security practices: 1. Coding Standards and Style 1. Naming Conventions Variables/Functions: Use <span>snake_case</span> (e.g., <span>user_name</span>, <span>calculate_sum</span>), avoid abbreviations (unless they are … Read more

The PLC ‘Black Box’: Advanced Diagnostics and Error Handling Mechanisms

by

Introduction No matter how stable a system is, unexpected issues can still arise. An excellent program not only runs correctly but also can “respond calmly” when a fault occurs, clearly informing maintenance personnel “where the problem lies.” This is the diagnostic and error handling function of a PLC, akin to an airplane’s “black box.” 1. … Read more

Typical Handling Example of Estun Robot

Using the ER6-600-SR to implement a standard handling project, the gripper has two suction cups, allowing the robot to pick up two items at once from the pickup location and place them sequentially at the same drop-off location, stacking them on top of each other. After stacking five times, a signal is given to indicate … Read more

Understanding Linux Redirection

Understanding Linux Redirection In Linux systems, redirection is one of the core functionalities of shell scripts and command-line operations. It allows users to flexibly control the flow of standard input (stdin), standard output (stdout), and standard error (stderr) of commands, enabling powerful features such as data piping, logging, and error handling. Redirection not only simplifies … Read more

After Over 5 Years of Python, I Realized That Python Source Files Should Not Be Named Arbitrarily

It’s that time again to decide what to have for lunch. I’m tired of the restaurants around the office, but I still need to eat. So, I decided to write a small program to let Python randomly choose a lunch menu for me. I casually created a source file named <span>random.py</span> (remember this filename!), and … Read more

by
New Features in C++26 - Uninitialized Reads

1. What are Uninitialized Reads Erroneous behaviour for uninitialized reads, or uninitialized reads. In traditional C++, UB (Undefined Behavior) is a very broad term; any behavior that does not fall under normal operations can be considered undefined. This overly broad definition often leads to a problem where, after an issue arises, it is difficult to … Read more

Unified Error Handling Middleware for Golang HTTP

by
Unified Error Handling Middleware for Golang HTTP

Unified error handling is implemented through middleware and the ErrorResponse structure, capturing panics and standardizing responses. The middleware uses defer and recover to prevent crashes, and the writeError function simplifies error returns, ensuring consistent and maintainable API error responses when integrated with routing. In Go language development for web services, unified error handling is key … Read more

Differences and Similarities Between Result and Option in Rust: Important Considerations for Using Unwrap

The <span>Result</span> and <span>Option</span> enums in Rust are central to error handling. They are designed for different purposes, but caution is required when using methods like <span>unwrap</span>. Below is a table and some points to help you quickly understand their differences and the considerations for using <span>unwrap</span>. Feature <span>Option<T></span> <span>Result<T, E></span> Main Purpose Handles scenarios … Read more
