درود
همونطور که میدونید iptables منقضی شده و بجاش nftables رو آوردن که بسیار داینامیکه و همین موضوع باعث شده که پرفورمنس بهتری داشته باشه
درکنار ساده‌تر شدن کلی امکانات جدید بهتون میده
مهاجرت از iptables به nftables خیلی ساده‌تر از اون چیزیه که فکرش رو بکنید
اگه iptables رو یاد گرفتید و بلدید دیگه استفاده از nftables براتون کاری نداره
شدیدا توصیه میکنم ازش استفاده کنید

اینم ویکی آرچ که خوب توضیح داده

Consider the following Go code snippet. What will be the output? (For answer choose an item in the poll 👇👇)

package main

import (
    "fmt"
    "sync"
)

func main() {
    var wg sync.WaitGroup
    var mu sync.Mutex
    counter := 0

    for i := 0; i < 5; i++ {
        wg.Add(1)
        go func() {
            defer wg.Done()
            for j := 0; j < 1000; j++ {
                mu.Lock()
                counter++
                mu.Unlock()

        }()
    }

    wg.Wait()
    fmt.Println("Final Counter:", counter)

Clean Architecture

Clean architecture isn't revolutionary. You need to follow one crucial principle: inner layers can't reference outer layers. Essentially, we're applying dependency inversion on the application level. Inner layers define abstractions, and outer layers implement these abstractions.

You can package Clean Architecture across multiple projects. This is the most common approach with a Domain, Application, Infrastructure, and Presentation project.

However, you can also group components for a single feature together. This is called a vertical slice, and it improves the cohesion of your design.

What are the benefits of Clean architecture?

- Modularity
- Separation of concerns
- Testability of business logic
- Improved team productivity
- Loose coupling of components

Binary Trees

A binary tree is a tree data structure where each node has no more than two children.

A binary tree can come in many forms, such as the following:

Full binary tree: every node has either zero or two children.

Complete binary tree: each level of the tree has a complete set of nodes, with the last level being the exception.

Perfect binary tree: Every level of the tree including the last level is complete.

Balanced binary tree: the depth of the left and right sub-trees of all nodes differ by no more than 1.

Binary search tree: each node is larger than all the nodes in their left sub-tree, and smaller than all the nodes in their right sub-tree.

Binary trees are great for storing ordered data for sort and search operations. Their strict structure and properties make these tasks highly efficient.

Some typical use cases are:

🔸 Search algorithms

🔸 Sort algorithms

🔸 Pathfinding algorithms

🔸 Representation of hierarchical data

Classes are often used to implement binary trees because of their ability to use encapsulation and abstraction.

A Node class is used to store its value and its left and right child. An insert function would be used to add a value relative to a given root node. Based on the binary tree type, it may need to travel through the tree to find its appropriate position. Based on your use case, you may want to have other methods like search and traverse.

Binary trees are integral to programming. They provide an essential building block for developing efficient algorithms and programs.

Using http.NoBody is better nil.

req := httptest.NewRequest(http.MethodGet, "/", http.NoBody)

It's zero allocation and safe no body for some methods.
