🟨 JavaScript 3 | **Simple Counter**
Published: 2024-01-07 07:41:58


New day new JavaScript beginner Exercise! Here is what I got from ChatGPT today, and my solution below as always 😊

# **Create a Simple Counter**

**Objective**: Build a web page with a button that, when clicked, increments a counter. This exercise will help you practice handling user events (like button clicks) and updating the webpage dynamically.

**Steps**:

1. **HTML Setup**: Create an HTML file with a button and a placeholder to display the counter's value.
2. **Initialize the Counter**: In your JavaScript, start with a variable set to zero. This will keep track of the counter's value.
3. **Increase Counter on Button Click**: Add an event listener to the button so that each time it's clicked, the counter variable increases by 1.
4. **Display the Counter**: Update the counter display on the webpage each time the button is clicked.
5. **Styling (Optional)**: Add some basic CSS to make your button and counter display look nice.

# My Code

Alright I am starting to get annoyed that I can’t remember the JavaScript syntax out of my head, because I was mostly able to do that with Python. But I guess that’s exactly why python is getting so popular: It’s so easy and obvious

Well anyways that doesn’t help me here. Instead I decided to recreate todays code so often until I can just write it on my own without any help of ChatGPT. Took me 4 attempts until I finally was able to do even tho it is so simple, phewww

Formatting Phone Number in JavaScript - Country Code + Leading Zero (0)
Published: 2024-01-07 07:33:53

To ensure that `smsPhone` is in the format `'+2547XXXXXXXX'`, you can modify the code as follows:

```javascript
// Assuming smsPhone is a variable holding the phone number
const formattedPhone = `+${smsPhone.replace(/^0/, '254')}`;

const response = await sms.send({
    to: [formattedPhone],
    message: smsMessage,
    enqueue: true
});
```

This code uses the `replace` function to replace the leading '0' in the phone number with '254' and then adds a '+' to the beginning. This ensures that the phone number is in the international format. Ensure that `smsPhone` is a string representing the phone number without the country code. The modified `formattedPhone` variable should then be used in the `to` field of the `sms.send` method.
Machine Learning - Data Preprocessing-2 label encoder, Splitting Data and Feature scaling
Tags: ai, machinelearning, beginners
Published: 2024-01-07 07:31:03

H all, So in this article we will discuss about  **label encoder**, **splitting data set** and then **feature scaling** it.
So let's start with **label encoder** these are basically used for encoding dependent variable which is Y here. so in data set we have values like yes or no , that will be encoded to numeric values of 0 or 1. We will use LablelEncoder from sklearn preprocessing and then transform the data as below

`from sklearn.preprocessing import LabelEncoder
le = LabelEncoder()
y = le.fit_transform(y)`

After we are done with this we can now **split the data** into Training and Test sets. Generally we keep 80% of data as training and rest as test set. It is useful for evaluating model performance once we are done training the model. This can be done via train_test_split from sklearn model_selection

`from sklearn.model_selection import train_test_split
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size = 0.2, random_state = 1)`

Once we have got 2 sets of data if our data needs to **Feature scaling** we will perform that using Standard Scaler from sklearn preprocessing . Here we use mostly Standardization method for Feature Scaling, there is also another method which is called normalization but mostly standardization is used. We will first scale training data and then using same scaling parameters test set will be scaled. It is recommended and general practice to scale after data splitting as test data should be unseen data to the model and if we split after scaling it will have data bias and our model might not perform in the way we intend.

`from sklearn.preprocessing import StandardScaler
sc = StandardScaler()
X_train = sc.fit_transform(X_train)
X_test = sc.transform(X_test)`

Now we have transformed data after preprocessing and ready to develop our models to predict values. We will cover it in future articles.

Hope it helped.

Space Complexity for Java Dev : Beginners
Published: 2024-01-07 06:41:02


**Scenario:**

Jr: My prime number finder uses a boolean array to mark non-prime numbers. How can we improve the memory usage?

Sr: The boolean array approach uses O(n) space. However, the Sieve of Eratosthenes algorithm provides an optimized way with the same space complexity but improved memory utilization.

Jr: How does Sieve of Eratosthenes work mathematically?

Sr: The Sieve algorithm works on the principle of eliminating multiples of prime numbers. It starts by marking all numbers as potential primes and iterates up to the square root of n. For each prime number found, it marks all of its multiples as non-prime. This method takes O(n log log n) time complexity and O(n) space complexity.

```java
public void sieveOfEratosthenes(int n) {
    boolean[] primes = new boolean[n + 1];
    Arrays.fill(primes, true);
    
    for (int i = 2; i * i <= n; i++) {
        if (primes[i]) {
            for (int j = i * i; j <= n; j += i) {
                primes[j] = false;
            }
        }
    }
    
    for (int i = 2; i <= n; i++) {
        if (primes[i]) {
            System.out.print(i + " ");
        }
    }
}
```

Jr: So, it's a more optimized way to mark non-primes without using extra space for a separate array?

Sr: Precisely! This algorithm is more efficient for larger ranges as it sieves out non-prime numbers mathematically.

Jr: Can we explore another example with Fibonacci?

Sr: Certainly! The recursive Fibonacci approach uses O(n) space due to the recursive function call stack. However, an iterative approach like this:

```java
public int fibonacci(int n) {
    if (n <= 1) {
        return n;
    }
    int prev = 0, current = 1;
    for (int i = 2; i <= n; i++) {
        int temp = current;
        current = current + prev;
        prev = temp;
    }
    return current;
}
```

Sr: Mathematically, this iterative version uses only O(1) space as it avoids creating those additional function calls. Understanding these complexities helps us select the most efficient approach for different scenarios and larger computations.

Converting a string to Base64 manually
Tags: webdev, javascript, beginners, tutorial
Published: 2024-01-07 05:57:24

As a web developer, you must have heard or even used Base64 encodings. Generally we convert some texts or urls to Base64 encoded string. To do this either, we use programming language's methods or we use some third party tools.

In this tutorial we are going to learn how we can encode any text into Base64 manually.

Lets say, we want to encode a text **"hi"** in base64 binary encoding. Why I am saying it as binary, because base64 encoding is one of the binary representations.


## Step 1: Text To ASCII ( text is "hi")
First, each character in the string is converted to its ASCII representation, For example:

```
h: 104       i: 105     
```

## Step 2: Convert each ASCII character to 8bit binary

```
01101000 01101001
```

## Step 3: Split these binary numbers into group of 6 bits.

```
011010 000110 1001
```

## Step 4: Padding(if required)
If you notice the least significant number doesn't have 6 bits, then add 0 (zeroes) at the end to make it 6bits

```
011010 000110 100100
```
**Just remember one thing here,
if we add two zeroes then we will be using "=" at the end of base64 string 
if we will add 4 zeroes then we will be using "==" at the end of base64 string**

## Step 5 Convert it to Decimal

```
26 6 36
```

## Step 6: Use Base64 Table to find out corresponding character encoding

Base64 Table - it contains 64 characters
```
ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/
```

```
   Value Encoding  Value Encoding  Value Encoding  Value Encoding
         0 A            17 R            34 i            51 z

         6 G            23 X            40 o            57 5
         7 H            24 Y            41 p            58 6
         8 I            25 Z            42 q            59 7
         9 J            26 a            43 r            60 8
        10 K            27 b            44 s            61 9
        11 L            28 c            45 t            62 - (minus)
        12 M            29 d            46 u            63 _
        13 N            30 e            47 v           (underline)
        14 O            31 f            48 w
        15 P            32 g            49 x
        16 Q            33 h            50 y         (pad) =
```
So, 
26 -> a
6 -> G
36 -> k

```
aGk
```

## Step 7 - Now add padding ( we added two zeroes, so we will use one equal(=) sign.
aGk=


You can also verify this with JavaScript method
btoa("hi") . It will also print same.

Speak in the language of the field you serve,
With variables and functions that reflect its verve.
Model concepts true, with classes standing tall,
Echoing the world's design, heeding its call.

Let banking systems speak of loans and funds,
Let healthcare software whisper of patients and lungs.
Let e-commerce dance with carts and checkout lines,
Each line of code a mirror, where reality shines.

For when code aligns with the world it seeks to tame,
Complexity melts away, replaced by clarity's flame.
Engineers and users united in thought,
A common tongue discovered, wisdom dearly bought.

No need for translation, no cognitive leap,
The code itself a story, with secrets to reap.
Domain experts guide, their insights unfurled,
As code becomes a canvas, reflecting their world.

So let variables sing in the language of the trade,
Let functions echo actions, no detail betrayed.
Shape your code around the problem's core,
And watch understanding blossom, forevermore.

For in this symphony of code and domain's embrace,
Lies a clarity profound, a vibrant grace.
Where software becomes a bridge, a faithful guide,
Uniting minds and solving problems, side by side.

Docker Scout
Tags: ibbus, dockerscan, dockerscout, vulnerability
Published: 2024-01-07 05:32:45

Docker scout is the replacement of the legacy docker scan. Docker Scout analyzes image contents and generates a detailed report of packages and vulnerabilities that it detects. Docker Scout can also help provide you with suggestions for how you can remediate issues discovered by this analysis.

Docker images by analyzing their contents and **generating a detailed report of any vulnerabilities** detected during the process. 


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/6a7vbuyj3qvn4a2edw8z.png)

Docker Scout’s key features include inspecting for common **vulnerabilities and exposures (CVE),**providing security recommendations, and seamless integration with continuous integration, continuous delivery (CI/CD) workflows, helping you discover and remediate vulnerabilities during development.

Docker scout can be used with the two below integration methods

1. Image analysis in the docker hub

2. Artifactory Integration

Docker Scout**analyzes new tags automatically when you push to that repository. Advanced image analysis is more than point-in-time scanning**, the analysis gets reevaluated continuously, meaning you don’t need to re-scan the image to see an updated vulnerability report.

To automatically analyze images running in **remote environments you need to deploy the Docker Scout Artifactory agent**. The agent is a standalone service that analyzes images and uploads the result to Docker Scout.
