Python was created in the late 1980s by **Guido van Rossum**. The first version of Python was released in 1991. Since then, Python has become one of the most popular programming languages in the world.

>"Python is a great first language, and a great last language." - Guido van Rossum

Python is a simple language to learn. The syntax is easy to understand, and there are many resources available to help beginners get started. Once you have learned the basics, you can start to build your own projects.

Python is also a powerful language. It can be used for a wide variety of tasks, including web development, data science, and machine learning. It is also used by many large companies, such as Google, Facebook, and Netflix.

### Here is a table of Python versions and their release years:

| Version | Year |
|---|---|
| Python 1.0 | 1991 |
| Python 2.0 | 2000 |
| Python 3.0 | 2008 |
| Python 3.1 | 2009 |
| Python 3.2 | 2010 |
| Python 3.3 | 2012 |
| Python 3.4 | 2014 |
| Python 3.5 | 2015 |
| Python 3.6 | 2016 |
| Python 3.7 | 2018 |
| Python 3.8 | 2019 |
| Python 3.9 | 2020 |
| Python 3.10 | 2021 |

#### Here is a sample Python code

```python
def factorial(n):
    if n == 0:
        return 1
    else:
        return n * factorial(n - 1)

print(factorial(5))
```

This code defines a function called `factorial()` that calculates the factorial of a number. The factorial of a number is the product of all the positive integers less than or equal to that number. For example, the factorial of 5 is 120.

The code first checks if the number is 0. If it is, then the function returns 1. Otherwise, the function recursively calls itself, passing in the number minus 1. The recursive call will eventually reach the base case, where the number is 0, and the function will return 1.

The code then prints the result of the `factorial()` function. In this case, the result is 120.

#### Summary

Python is a powerful and versatile programming language that is easy to learn. It is a great choice for beginners and experienced developers alike. If you are looking for a programming language to learn, I highly recommend Python.

Unleashing the Code: Python Car Game Coding Adventure
Tags: webdev, beginners, programming, devops
Published: 2023-07-13 05:21:17

Certainly! Here's an example of a simple car game coded in Python using the Pygame library:

```
import pygame
import time
import random

# Initialize Pygame
pygame.init()

# Set up the game window
width = 800
height = 600
game_display = pygame.display.set_mode((width, height))
pygame.display.set_caption("Car Game")

# Set up colors
white = (255, 255, 255)
black = (0, 0, 0)
red = (255, 0, 0)

# Set up the clock
clock = pygame.time.Clock()

# Set up the car attributes
car_width = 73

# Load the car image
car_img = pygame.image.load("car.png")

def car(x, y):
    game_display.blit(car_img, (x, y))

# Display message
def message(msg, color):
    font_style = pygame.font.SysFont(None, 50)
    message_render = font_style.render(msg, True, color)
    game_display.blit(message_render, [width / 6, height / 3])

# Main game loop
def game_loop():
    game_over = False
    x = width * 0.45
    y = height * 0.8
    x_change = 0

    # Game loop
    while not game_over:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                game_over = True
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT:
                    x_change = -5
                if event.key == pygame.K_RIGHT:
                    x_change = 5

            if event.type == pygame.KEYUP:
                if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
                    x_change = 0

        x += x_change

        game_display.fill(white)
        car(x, y)

        # Set boundaries for the car
        if x > width - car_width or x < 0:
            game_over = True

        pygame.display.update()
        clock.tick(60)

    pygame.quit()
    quit()

# Run the game
game_loop()

```
In this car game, the player controls a car using the left and right arrow keys. The objective is to navigate the car within the game window without hitting the boundaries. The game loop handles user input, updates the car's position, and checks for collisions.

Feel free to modify and enhance the code to add additional features, such as obstacles, scoring, or levels. Game coding allows for endless possibilities, so let your creativity shine and have fun exploring the world of game development!
Exploring the Power of PostgreSQL and Postgres Enterprise Manager
Published: 2023-07-13 05:43:01

Greetings, fellow developers,

PostgreSQL is a potent, open-source object-relational database system that many of you are undoubtedly familiar with. It boasts extensive expandability and adheres to standards, making it a favored choice for numerous developers. The latest release, PostgreSQL 15, introduces numerous new features and enhancements that augment its performance, resilience, and functionality.

PostgreSQL's commitment to standards compliance and adaptability is truly admirable. Arrays, user-defined types, and multidimensional arrays are supported. Also, PostgreSQL offers comprehensive functionality for searching and indexing text.

However, managing PostgreSQL databases can prove to be quite intricate, particularly as your data expands. This is where the remarkable Postgres Enterprise Manager comes into play. PEM serves as a comprehensive management tool that simplifies the arduous task of overseeing, monitoring, and fine-tuning PostgreSQL and EDB Postgres Advanced Server databases.

PEM facilitates this by offering a user-friendly web-based interface, allowing you to effectively manage multiple Postgres clusters from a centralized location. It presents an array of tools for SQL development, job scheduling, alerting mechanisms, and more. Personally, I find the capacity manager feature to be particularly noteworthy as it aids in monitoring the overall health and performance of your database over time.

PEM combined with PostgreSQL has significantly simplified database management tasks. The synergy between the two is undeniably powerful, and this combination is highly recommended to any developer working with large-scale PostgreSQL databases.

In summary, the powerful duo of PostgreSQL's robustness and adaptability, complemented by PEM's management capabilities, presents a potent toolkit for software engineers. Whether one possesses expertise in PostgreSQL or is a novice exploring its possibilities, it is encouraged to explore these tools and discover how one can enhance ones database management endeavors.

3 essential tools for your JSON objects
Tags: json, tooling, developers
Published: 2023-07-13 04:45:19

This is a short listicle

As a developer, it is sometimes difficult to work with JSON. Especially if you are working with third-party APIs. The structure of the object is not in your control. And you have to work with what you get.

Here are 3 tools that I found super helpful in scenarios like this

### **1\. JSONLint**

JSONLint is a validator and reformatter for JSON. You can copy paste, or directly type in the editor and it validates and format your messy JSON.

Link: [https://jsonlint.com](https://jsonlint.com/)

### **2\. JSON Editor Online**

It allows you to transform and compare your JSON. You can Configure schema, inspect and query JSON with ease.

Link: [https://jsoneditoronline.org](https://jsoneditoronline.org/)

### **3\. JSON Path Finder**

It allows you to find the path of an item in a JSON object. You can expand and select elements in a tree view. And it gives the dot notation of the currently selected piece of data.

Link: [https://jsonpathfinder.com](https://jsonpathfinder.com/)

Let me know in the comments if you know something better.

I hope you find this valuable, if you did - awesome **👌** share it with your folks if it's relevant to them. If you have any suggestions/comments please feel free.

Happy coding!

When To Use Graph Database Model Over Relational Database Models
Tags: postgres, apacheage
Published: 2023-07-13 04:39:51

There are a lot of different database models out there. Nothing is right and wrong, it all depends on the cases and the requirements of the project, the blog will focus on when to use Graph databases over relational ones.

## When to use a Graph model?

1. When Complex relations exist between data. A general and common case is when building a social media app, you will most probably use a Graph model to handle relations between users, as graph model will be much easier structure to handle complex interconnected data.

1. When project data model is inconsistent and requires frequent changes. Given social media app as an example, the shape of data will often be changed as demands and requirements change, so having flexible data model is necessary

1. When Additional attributes are only necessary for some entities (not all of them), in these cases working with relational databases will force you to create a separate table (best practices) to handle additional attributes rather than having (null) value for those attributes in rows that don't have values for them, so it's harder to handle those type of issues in relational models than in graph models which is simpler, and changing the data structure at any point in time is easier

1. Running reading queries is simpler with cypher than sql in a lot of cases


Graph models is not always the best suited, you should always think in terms of performance, which type of databases will bring the best performance possible?, also what type of queries I will often be running?, what kind of data you are working with?, and more importantly what expertise your team has?. Thinking in terms of all of these is important to make the right decision and choose the most suited database model to fit your needs. 

I've been using postgres for a quite a long time, and I came recently across an extension that add and power postgres with graph functionalities, the extension is `apache/age` which is worth checking for those want to leverage both graph and relational databases functionalities in a single database.
"Should I learn Monads?"
Tags: monad, functional, haskell, purescript
Published: 2023-07-13 04:37:00

- This is written (or thought) from the perspective of a JS developer who discovered functional programming as recently as 2019 and has used monads.
- This is not a tutorial on monads, by the way.

---

Absolutely.

It's quite normal for JS developers to be okay with doing `possibleObject.someProperty` when `possibleObject` is not guaranteed to be an object in the first place. That is, it could be "null" or "undefined". Learning monads and using them (the `Maybe` monad in this case) has helped me be aware of and mitigate this risk (of property access in vanilla JS). Now, I use `get` from Lodash or the fancier `S.prop` from [Sanctuary](https://sanctuary.js.org) depending on the project.

Functions that could throw errors (known and unknown) will need to be handled with try catch blocks. The `Either` monad has helped me not only be more conscious about such functions when I use them but also model my data structures and pipeline functions better to handle this easily. Think of this: instead of `try catch` all over the place, I wrap functions in a way that they will return a tuple of `[error, data]` and I just need to check for either to be `null` to know if the function worked or failed. No `try catch` blocks all over the place.

Monad's `bind` and `map` have helped me understand how useful such functions are when dealing with pipelines and data transformation (which is about 80% of my work). Maybe they are only useful when you write code in a functional-style but the utility is enormous nevertheless.

Learning monads has also helped me quickly identify certain patterns (for example, think of running an array of promises parallely and then processing the result. In JS, this is `[Promise<value1>, Promise<value2>, Promise<value3>]` but using this data as-is is a messy business. But if you convert this into a `Promise<[value1, value2, value3]>`, suddenly, you only have to unwrap a single promise (via `await`) to get all the values and have fun using simple, synchronous array functions. This idea is called `sequence` and within the FP-world, most libraries provide this function).

### Learning monads

While this is a completely subjective feeling, I think the best way to learn about monads would be to actually build them from scratch.

The [monad challenges](https://blog.curlyfri.es/monad-challenges-purescript/) were hard. I spent days solving some of them and had to rope in some help from the FP community.

But in the end, while I came out of it battered, some of the core ideas of monads (and why we have them in the first place) got ingrained in me. And they've made writing and approaching problems (to be solved through code) much easier.
Exploring the Base64 Encoding and Decoding Functions in JavaScript: btoa() and atob()
Tags: javascript, encode, decode, base64
Published: 2023-07-13 04:15:07

**Introduction:**
In JavaScript, the btoa() and atob() global functions are essential tools for handling Base64 encoding and decoding. The btoa() function allows you to create a Base64-encoded ASCII string from a binary string, treating each character as a byte of binary data. On the other hand, the atob() function decodes a Base64-encoded string back into its original form. This article delves into the syntax, usage, and examples of these functions, emphasizing their significance in JavaScript development.

**Encoding with btoa():**
The btoa() method enables the conversion of a binary string into a Base64-encoded ASCII string. It is particularly useful for encoding data that may encounter communication problems during transmission. By employing the btoa() function, you can encode various types of information, including control characters represented by ASCII values ranging from 0 to 31.

**Decoding with atob():**
The atob() function acts as the counterpart to btoa(), allowing you to decode a Base64-encoded string back into its original binary representation. By utilizing atob(), you can reliably retrieve encoded data and restore it to its original form.

Example Usage:
Let's explore an example to illustrate the usage of btoa() and atob() functions in JavaScript:

```
const encodedData = btoa("Hello, world"); // 'SGVsbG8sIHdvcmxk'
const decodedData = atob(encodedData); // "Hello, world"
```

In the above code snippet, we start by utilizing the btoa() function to encode the string "Hello, world." The resulting Base64-encoded data is stored in the variable encodedData. Subsequently, we employ the atob() function to decode the encodedData, and the original string "Hello, world" is obtained and stored in the decodedData variable.

**Conclusion:**
The btoa() and atob() global functions in JavaScript are invaluable tools for handling Base64 encoding and decoding. With btoa(), you can encode binary strings into Base64-encoded ASCII strings, while atob() allows for the reverse process of decoding Base64-encoded strings back to their original form. Understanding and utilizing these functions empower front-end developers to work with encoded data, enabling reliable transmission and retrieval of information. Be mindful of the limitations when working with Unicode strings, and refer to appropriate resources to address such scenarios effectively.

Quick Tips: Styling MUI Components with the sx Prop
Published: 2023-07-13 03:50:06

### **Elevate Your MUI Components: Mastering the `sx` Prop for Styling**

Material-UI (now known as MUI) has always been a popular choice among React developers for its rich component library and flexibility. One of the game-changers introduced in MUI is the `sx` prop, which provides a powerful and concise way to style components directly. In today's quick tip, we'll explore how to use the `sx` prop to change button hover effects and to integrate images seamlessly into Box components.

---

To change a button color on hover with MUI, you can use the inline css `sx` prop with ":hover".

Example:
```jsx
<Button
  variant="contained"
  sx={{bgcolor: "#525252",
       ":hover": {bgcolor: "#5c5c5c",color: "white"},
     }}
>
Click Me
</Button>
```

To put an image into a box component, you can set 'component="img"'.
```jsx
<Box
   component="img"
   src={`http://localhost:4000/${cover}`}
   sx={{
        // Match the width of the image to the parent element
        width: "100%", 
        height: "auto", 
        maxWidth: "250px", 
        maxHeight: "200px", 
        borderRadius: "10px",
        objectFit: "cover",
      }}
 ></Box>
```
