Explains Rust’s Copy and Clone traits, their differences, implementation, and best practices.
SQLAlchemy is the most popular Object Relational Mapping (ORM) in the Python ecosystem. It has an elegant design and is divided into two parts: the underlying Core and the upper-level traditional ORM. In most ORMs in Python and even in other languages, a good hierarchical design has not been implemented. For example, in Django's ORM, the database connection and the ORM itself are completely mixed together.
An HTTP Server, as understood from its name, is a server that supports the HTTP protocol. While a Web Server, in addition to supporting the HTTP protocol, may also support other network protocols. This article will focus on introducing several common ways to write a Web Server using the official package of Golang.
Best practices for organizing Rust projects, from basic crate structures to complex workspaces.
A practical introduction to Rust’s Ordering for atomic operations and reliable concurrency.
This language itself has many remarkable features, such as a more robust type system, more pure functional programming support, powerful language features, and a compiler written in a native language with extremely high performance. Of course, it also has corresponding disadvantages. This article will focus on introducing ReScript's powerful features, its surrounding ecosystem, and its integration with React, which is most closely related to our daily use.
In the world of Golang, timers have a wide range of application scenarios. However, the question of exactly how precise they are has always been a concern for developers. This article will delve deep into the management of the timer heap in Go and the mechanism for obtaining time at runtime, thus revealing to what extent we can rely on the accuracy of timers.
Techniques to enhance Rust's multithreading performance by refining Arc and lock usage.
Hugo is a static website page generation tool written in Golang, and its efficiency is much higher than that of Jekyll written in Ruby. You can directly download the binary package from Github, and after decompression, add it to the PATH environment variable to use it.
In the field of software development, testing the performance of Golang locks is a practical task. Recently, a friend raised a question: when performing thread-safe read and write operations on a slice, should one choose a read-write lock (rwlock) or a mutex lock (mutex), and which lock has better performance? This question has triggered an in-depth discussion.
A comparison of message push strategies to help you choose the right solution for your needs.
Compilation optimization refers to the use of various technical means during the compilation process to improve the execution efficiency and resource utilization efficiency of the generated code. The Go language compiler will automatically perform some basic optimizations. However, through reasonable code design and compilation parameter settings, the program performance can be further improved.
Learn how to optimize Rust compilation for minimal size, maximum speed, or a balance of both.
A practical guide to choosing between Rust macros and functions for clean, efficient, and maintainable code.
With its efficiency (in terms of size) and professionalism (professional types), Protobuf should have a higher coverage in the future data transmission field.
In the Go language, there are two keywords that often appear in pairs — panic and recover. These two keywords are closely related to defer. They are both built-in functions in the Go language and provide complementary functions.
Optimize resource loading with fetchpriority to improve web performance and user experience. Engineering
`errgroup` is an official extended library that adds error handling capabilities on the basis of `sync.WaitGroup`, providing functions such as synchronization, error propagation, and context cancellation. Its `WithContext` method can add a cancellation function, `SetLimit` can limit the number of concurrency, and `TryGo` can try to start a task. The source code is ingeniously designed and worthy of reference.
In Python, a decorator is essentially a Python function. It has unique capabilities that allow it to add additional functionality to other functions without modifying their original code. The return value of a decorator is also a function object. In simple terms, it is a function specifically designed to return another function.
A technical breakdown of Fast Refresh, React’s modern approach to hot reloading and component updates.
Mentioned that when the native HTTP server in Go handles client connections, it spawns a goroutine for each connection, which is a rather brute - force approach. To gain a deeper understanding, let's take a look at the Go source code.
A guide to handling Node.js process exits, preventing crashes, and ensuring smooth recovery.
In front-end development, project optimization is a crucial aspect of improving performance. One common optimization strategy is to appropriately replace embedded small images with Base64 strings to reduce the number of HTTP requests on a page. Meanwhile, it's emphasized that these should be small images, usually with a size not exceeding a specific number of kilobytes. So, what exactly is Base64? And why can it play a role in front - end optimization? Let's explore in depth together.
A guide to idempotency, its importance in software engineering, and techniques to ensure data integrity and reliability.
When you hear "functional programming," Go usually isn't the first language that comes to mind. You might think of Haskell, with its pure functions and monads (don't panic, we'll explain that in detail later), or JavaScript, which loves to showcase its features with higher - order functions and callbacks. But in fact, you can also do functional programming in Go, and the process is far from dull.
How HTTP caching works: strong caching, negotiated caching, and best practices for efficiency.
In the world of the Internet, the HTTP protocol is undoubtedly a fundamental protocol and essential knowledge in the field of web development.
