Published: 2024-05-17 05:21:05

- First check the Go version by running the command 
```
go version
```

- Create a folder

```
mkdir <folder_name>
```

- Switch to created folder 

```
cd <folder_name>
```
 

- Initialize the go project by running the given command. You will get `go.mod` file.
```
go mod init <folder_name>
```


- Create a `main.go` file, use terminal or bash

```
notepad main.go 
touch main.go
```

- Let's write some basic code in `main.go` file. 

```go
package main 

import (
	"fmt"
)


func main() {
	fmt.Println("MongoDb with Go")
}

```

- Run the code by following command 

```
go run main.go 
```

- You will see this output in console 

```
MongoDb with Go
```

- Install some packages to connect MongoDB in Go. Here are commands

```
go get go.mongodb.org/mongo-driver
go get go.mongodb.org/mongo-driver/mongo
```

- Revisit the `main.go` file to connect MongoDB.  This is our full code 

```go
package main

import (
	"context"
	"fmt"
	"log"

	"go.mongodb.org/mongo-driver/mongo"
	"go.mongodb.org/mongo-driver/mongo/options"
)

// mongodb connections
var collection *mongo.Collection
var ctx = context.TODO()

func init() {
	clientOptions := options.Client().ApplyURI("mongodb://localhost:27017/")
	client, err := mongo.Connect(ctx, clientOptions)
	if err != nil {
		log.Fatal(err)
	}

	// check connection
	err = client.Ping(ctx, nil)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println("Connected to MongoDB!")

	collection = client.Database("testingWithGo").Collection("movies")
}

func main() {
	fmt.Println("MongoDb with Go")
}

```

- Run the code by following command again 

```
go run main.go 
```

- You will see this output in console 

```
Connected to MongoDB!
MongoDb with Go
```

That's for today. Thank You .

F# For Dummys - Day 6 Format
Tags: fsharp
Published: 2024-05-17 03:48:15

Today we learn how to format the output of println, and a new type char</br>

### what is formatting?
formatting is converting values into strings according to a specified format</br>
we introduce 2 ways to format:

- 
**String interpolation**: one way to combine variables and text is to use something called interpolation</br>
actually we used it yesterday
```
let name = "Lucy"
let age = 14
printfn $"my name is {name}, I'm {age} years old"
```
$ tell the compiler: please use the variable we defined before in this string</br>
{} indicate what exactly the variables we need, here in this example is {name} and {age}</br>
so it will replace the value of variables at the location of brace</br>
like type of age is int, it's converted to string '14' in the final output, we didn't transfer it explicitly

- 
**Specifiers**: You can also use format specifiers as part of what you're trying to print. Using specifiers is the most commonly used way to format in F#</br>
Let's use specifier to format in our example:
```
let name = "Lucy"
let age = 14
printfn "my name is %s, I'm %i years old" name age
```
you can see the output is the same</br>
%s is for name, it's for string type</br>
%i is for age, it's for int type</br>
we introduce 4 of them today:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/e0npkbtrsw8ru2bznjf6.png)

%b for bool
```f#
let is_this_apple = true
let is_this_orange = false

printfn "Is this an apple? %b" is_this_apple
printfn "Is this an orange? %b" is_this_orange
```
%c for char</br>
we have learned string type to describe a text, it represents a sequence of characters</br>
while char represents a single character, like 'a', 'b', 'c', 'd' or '!', '@', '#', '$'</br>
string and char are different types, not just the length, you can not concat them like this:
```f#
let str = "Hello"
let ch = '!'
let result = str + ch

printfn "%s" result  // Output: Hello!
```
will get error: The type 'char' does not match the type 'string'

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/4ugsgbgplk5urhm45247.jpg)

we can transfer a char to string like this, then can concat them properly
```f#
let str = "Hello"
let ch = '!'
let result = str + (string)ch

printfn "%s" result  // Output: Hello!
```

  - [Wireless Routers](#wireless-routers)
  - [Other Types of Routers](#other-types-of-routers)

Main types of routers available and their unique features to help you pick the perfect one for your needs.

## Broadband Routers

- **Broadband routers:**
  - Popular for connecting computers and to the Internet.
  - Necessary if you use Voice over IP (VOIP) technology and connect to the Internet through a phone line.
  - Often a special type of modem (ADSL) with both Ethernet and phone jacks.

- **Advantages of broadband routers:**
  - Equipped with a modem, eliminating the need for an additional device to connect to the Internet.
  - Offer fast internet speeds.
  - Can connect multiple devices.


- **Potential drawbacks of broadband routers:**
  - Susceptible to hacking and unauthorized access if not properly secured.
  - Wireless broadband routers can experience interference from other electronic devices, leading to signal drops or reduced speeds.
  - The wireless signal range can be limited, especially in large homes or offices, potentially requiring additional equipment like range extenders.

## Wireless Routers
- **Wireless routers have become increasingly popular:**
  - Create a wireless signal in your home or office.
  - Allow any PC within range to connect and use the Internet.

- **Advantages of wireless routers:**
  - Provide internet access to multiple devices without wires or cables.

- **Potential drawbacks of wireless routers:**
  - Less secure than wired routers, as anyone within range can potentially access your network.

## Other Types of Routers

- **Edge Routers:**
  - Placed at the edge of the ISP network.
  - Configured to external protocols like BGP (Border Gateway Protocol) to connect with other ISPs or large organizations.
  
- **Subscriber Edge Routers:**
  - Belong to an end-user organization (e.g., enterprise).
  - Configured to broadcast external BGP to the provider's AS(s).
  
- **Inter-provider Border Routers:**
  - Used for interconnecting ISPs.
  - BGP-speaking routers that maintain BGP sessions with other BGP routers in different providers' ASes.
  
- **Core Routers:**
  - Located within the middle or backbone of the LAN network, not at the periphery.
  - Provide a step-down backbone, connecting distribution routers from multiple buildings on a campus (LAN) or large enterprise location (WAN).
  - Optimized for high bandwidth.

- **Wired and Wireless Routers:**
  - Popular for home and small office networking.
  - Maintain routing and configuration information in their routing tables.
  - Filter incoming and outgoing traffic based on IP addresses.

In today’s digital-age, identity verification is crucial for securing online activities and transactions. As more services move online, authenticating users remotely requires innovative techniques beyond static passwords or photos that can be easily faked. One emerging solution gaining traction, especially for companies like MiniAiLive, is face liveness detection, which uses advanced computer vision algorithms to determine if a live human is present rather than photo or video spoofing.

https://leetcode.com/problems/delete-leaves-with-a-given-value/?envType=daily-question&envId=2024-05-17

```javascript
/**
 * Definition for a binary tree node.
 * function TreeNode(val, left, right) {
 *     this.val = (val===undefined ? 0 : val)
 *     this.left = (left===undefined ? null : left)
 *     this.right = (right===undefined ? null : right)
 * }
 */
/**
 * @param {TreeNode} root
 * @param {number} target
 * @return {TreeNode}
 */
var removeLeafNodes = function (root, target) {

    if (!root) return null

    root.left = removeLeafNodes(root.left, target)
    root.right = removeLeafNodes(root.right, target)

    if (root.val === target && !root.left && !root.right) {
        return null;
    }

    return root
};

```

traverse the left and right sub-tree, get to the last node, if it is the target, remove it by making it null, else do nothing. Perform this recursively.
Protecting Your Self-Written JavaScript Code from Unauthorized Use
Tags: javascript, webdev, programming, obfuscation
Published: 2024-05-17 01:57:15

To prevent others from directly "stealing" or unauthorized use of your JavaScript code, which is inherently executed on the client-side and can be viewed and modified by users, you can employ several strategies. Here is a translation of the previous answer into English:

1. **Code Obfuscation:**
   Use tools like JShaman or JS-Obfuscator to obfuscate your JavaScript code, making it difficult to read and understand. This won't deter a determined attacker, but it can deter most casual users.

2. **Code Splitting and Modularization:**
   Split your code into multiple modules and utilize modern front-end frameworks (such as React, Vue, Angular) and bundlers (like Webpack, Rollup) for packaging. This way, even if someone views the source code, they'll find it challenging to trace and understand the relationships between various parts.

3. **Copyright Notice and Licensing:**
   Include a copyright notice and licensing information at the top of your code, specifying the type of license you're using (e.g., MIT, Apache, etc.). This won't prevent code theft, but it provides legal protection and clarifies how you want your code to be used.

4. **Access Control and Authentication:**
   If your code relies on backend APIs or services, ensure these APIs or services are protected with appropriate access control and authentication. This way, even if someone gets your frontend code, they can't interact with the backend without proper credentials.

5. **Encrypt Sensitive Data:**
   Do not hardcode any sensitive data (such as API keys, passwords) in your frontend code. Instead, use secure backend mechanisms (such as HTTPS and OAuth) to transmit and validate such data.

6. **Use CDN and Version Control:**
   Serve your JavaScript code through a CDN (Content Delivery Network) and utilize version control to manage different versions. This makes it easier to track and manage the distribution and usage of your code.

7. **Monitoring and Alerts:**
   Use web analytics tools and logging to monitor the usage of your code. Set up alerts to notify you of abnormal behavior, such as excessive requests from unknown sources or unusual API call patterns.

8. **Limit Functionality:**
   If possible, restrict certain critical functionalities to only authenticated and authorized users. This can be achieved through backend validation, user session management, or frontend token systems.

9. **Legal Measures:**
   If you believe your code is being used or distributed illegally, you can consider taking legal action to protect your rights. This includes suing infringers, seeking compensation, or obtaining injunctions.

Please note that no method can completely prevent unauthorized use of your code. The strategies mentioned above are only meant to mitigate such risks. Always consider security and privacy best practices when writing and distributing your code.
Understanding Node.js: A Comprehensive Guide
Tags: javascript, webdev, programming, node
Published: 2024-05-17 01:52:49

Node.js has revolutionized the way developers build scalable and efficient web applications. Its event-driven, non-blocking I/O model makes it a preferred choice for server-side development. In this comprehensive guide, we'll explore what Node.js is, its core features, how to get started, and delve into some advanced concepts.

## What is Node.js?
Node.js is an open-source, cross-platform JavaScript runtime environment that executes JavaScript code outside of a web browser. Developed by Ryan Dahl in 2009, Node.js allows developers to use JavaScript to write server-side code, making it possible to build full-stack applications using a single programming language.

## Key Features of Node.js

1. Asynchronous and Event-Driven: Node.js operates on an event-driven architecture and asynchronous I/O. This means operations do not block the execution thread, making it highly efficient for I/O-intensive tasks.

2. Single-Threaded but Highly Scalable: Despite being single-threaded, Node.js can handle multiple connections concurrently, thanks to its event loop.

3. Fast Execution: Built on the V8 JavaScript engine, Node.js compiles JavaScript into native machine code, ensuring fast execution.

4. NPM (Node Package Manager): With a vast repository of open-source packages, NPM makes it easy to manage project dependencies.

5. Cross-Platform Compatibility: Node.js runs on various operating systems, including Windows, Linux, and macOS.
