Short-circuiting
Tags: python, programming
Published: 2023-09-16 06:56:51

Short-circuiting is not unique to Python; it's a feature found in many programming languages, including but not limited to JavaScript, Java, C++, and C#

The core principle remains consistent: evaluation stops as soon as the final outcome is determined.

In Python, Short-circuiting behavior is evident in the use of logical operators like `or` and `and`. The key principle is that these operators will stop evaluating as soon as the outcome is determined. This feature has several implications, both for performance and functionality.

### `or` Operator

As you've seen in the previous example, the `or` operator will evaluate operands from left to right and return the first "truthy" value it encounters. If no "truthy" value is found, it returns the last "falsy" value.

```python
result = None or '' or 0 or 'first_truthy' or 'second_truthy'
# result will be 'first_truthy'
```

### `and` Operator

The `and` operator also evaluates operands from left to right but stops as soon as it encounters a "falsy" value and returns it. If all operands are "truthy," it returns the last "truthy" value.

```python
result = 1 and 2 and 'third_truthy' and None and 'not_evaluated'
# result will be None
```

### `if` and `elif` Statements

Short-circuiting can also occur in `if` and `elif` statements, where later conditions aren't evaluated if an earlier condition has already been met:

```python
if cheaper_function() or expensive_function():
    # expensive_function will not be called if cheaper_function returns True
```

### Nested Logical Operations

You can combine `or` and `and` in nested conditions. Be cautious here, as readability can become an issue.

```python
result = func1() or (func2() and func3())
# If func1() is truthy, neither func2() nor func3() will be evaluated.
```

### Implications

1. **Performance Optimization**: Short-circuiting can be leveraged to improve performance by placing less expensive or faster-to-evaluate conditions earlier in the logic chain.

2. **Conditional Side Effects**: If a function or operation inside a logical expression has side-effects (like database operations), those side-effects may not occur if short-circuiting prevents their evaluation.

3. **Readability and Maintenance**: While short-circuiting can make code more efficient, it can also make it less readable if overused or implemented without clarity.
Case Study: Amplifying Graph Database Power with PostgreSQL and Apache AGE - Part 1
Published: 2023-09-16 06:56:44

**Summary:**
A prominent social media company faced difficulties managing the extensive data produced on its platform due to the limitations of its conventional relational database management system. This system struggled with the intricate and interrelated data structures typical of social networks. Consequently, the company decided to explore graph database solutions and ultimately opted for the implementation of PostgreSQL with the Apache AGE extension.

**Challenges:**
The existing relational database management system proved inadequate for handling the intricacies of social network data, particularly in representing and querying the diverse relationships between users, such as followers, likes, and shares. Furthermore, the company needed a solution capable of scaling to manage the massive volume of data generated on its platform.

**Solution:**
To overcome these challenges, the company adopted PostgreSQL with the Apache AGE extension. This extension empowered the company to depict social network data as a graph, simplifying the process of querying and analyzing the complex user relationships. Additionally, the extension's advanced indexing and querying features enabled faster and more efficient data retrieval, a crucial requirement given the company's platform's scale.

**Quotes of the day**

> Kal kare so aaj kar, aaj kare so ab.

Hi, everyone welcome back to my blog series. In the last blog, I shared a post in which, I said that I'd start a blog series where I'll post a project series-wise in which I'll use new technologies like <code>ASPN.NET Core Web API</code>, `Angular` and `Azure` and more.

I'll start a project named Buttler, which I created during my college time period. So I will share their ER-Diagram and DFD to better understand the project in this post.

This project is nothing but for learning those technologies are best practices. It is a food ordering system in which there are 3 types of users `Admin`, `Staff`, and `User`, where users can make orders for their food items and track their order status or cancel their orders.
On the other hand admin and staff users can update their food status for tracking. Admin can create new staff users and manipulates them according to their requirement, where staff can manipulate the users. Never mind you can understand better when you see the **DFD** which is given below.


![DFD diagram](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/gci4c7pzu37lcrexxwki.png)

So now you can understand the flow better.
Now moving to the Entities we'll use in this project are, given below.


![ER-diagram](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/vtctlb3go2tjc7q9jd51.png)

We'll create those entities with a Code-First approach and everything will be code-first, if you're not good at the code-first approach then you can begin with the database-first approach you can use that ER to create or make tables in your database.

So that's all from my side in this post, see in the next post with the monolithic project structure of **ASP.NET Core Web API**.

Tuple Immutability
Tags: python
Published: 2023-09-16 06:37:19

In Python, the immutability of a tuple refers to the fact that once a tuple is created, its structure cannot be altered. Specifically, you cannot add, remove, or change elements within the tuple itself. 

However, this immutability is shallow, which means that if a tuple contains mutable elements—like lists or dictionaries—those elements themselves can be modified.

### What Does Immutability Mean?

When we say tuples are immutable, it implies that the tuple object itself cannot change after its creation:

```python
# Immutable: Cannot change the tuple itself
my_tuple = (1, 2, 3)
# The following line would cause an error
# my_tuple[1] = 4
```

### Mutable Objects Inside Tuples

Despite the tuple's immutability, any mutable objects inside the tuple can be modified:

```python
# Tuple with a list (mutable object) inside
my_tuple = (1, 2, [3, 4])

# Modifying the internal list is possible
my_tuple[2][0] = 5
# my_tuple becomes (1, 2, [5, 4])
```

### Implications in a Professional Setting

Understanding the shallow immutability of tuples is crucial in various scenarios:

1. **Data Integrity**: If you are dealing with configurations or settings that should remain constant throughout the program, using tuples makes sense. However, you must be cautious if these tuples contain mutable types, as those can still be altered.
  
2. **Performance**: Given that tuples are immutable, they are generally faster for read-only operations compared to lists. This could be advantageous in performance-critical sections of your code.

3. **Multi-threading**: The immutability of tuples makes them inherently thread-safe for the tuple elements themselves, but not necessarily for mutable objects contained within.

4. **Program Architecture**: If your application requires a constant set of parameters, especially in a complex system architecture where parameters are passed through multiple functions or layers, using tuples can serve as a form of documentation that these should not be modified.

Nerve Regen Formula the dietary arrangement made solely to fix the seriousness in neuropathic torment paying little heed to mature or orientation. As found in the authority site supplement was made by Kevin Mill operator, a restorative physicist who wishes to spread mindfulness in dealing with the solid nerve capabilities. As per him his definition of Nerve Regen Formula assists with forestalling the bone pounding torment and make ordinary. According to its true site, the Nerve Regen Formula enhancement is the normal and compelling mix of nutrients, plants and spices that could uphold with the sound nerves. It likewise helps in alleviating from the horrible neuropathic agony, fix and revive the nerves. This is made conceivable by the maker by adding the outlandish impacts of fixings like "Passiflora In essence and Corydalis Yanhuosuo, California poppy seeds, Thorny pear and Marshmallow root". According to the authority site, these fixings support solid sensitive spots, nerve unwinding and mends them from torment. It is made sufficiently strong to give the ideal outcomes and to upgrade the outcomes there are not many sound tips included by the maker that consolidates with the enhancement.

Solving "All Nodes Distance K in Binary Tree" Leet code Question
Tags: beginners, java, programming, tutorial
Published: 2023-09-16 06:00:00

## Problem Statement
Given a binary tree, you are given a target node `target` and an integer `k`. Return a list of all the values that are at a distance `k` from the target node in the tree.

## Approach
The idea to solve this problem is to perform a depth-first search (DFS) traversal of the binary tree to find nodes at a distance `k` from the target node. We'll use a few helper functions to achieve this.

1. **UpdateParent Function**: We'll start by creating a mapping of each node to its parent node. This will help us navigate the tree later.

2. **Traversal Function**: In this function, we'll perform the DFS traversal. When we reach a node at a distance `k` from the target node, we add its value to the result list. We also maintain a `HashSet` to keep track of visited nodes to avoid revisiting them. The recursion continues until we either find nodes at distance `k` or reach the end of the tree.

3. Finally, in the `distanceK` function, we initialize the necessary data structures and call the `UpdateParent` function to create the mapping of nodes to their parents. Then, we call the `Traversal` function to find nodes at distance `k` from the target node and add their values to the result list.

## Complexity Analysis
- Time Complexity: The DFS traversal of the binary tree takes O(n) time, where n is the number of nodes in the tree.
- Space Complexity: The space complexity is O(n) due to the space used by the HashMap, HashSet, and the recursion stack.

## Code :

```

/**
 * Definition for a binary tree node.
 * public class TreeNode {
 *     int val;
 *     TreeNode left;
 *     TreeNode right;
 *     TreeNode(int x) { val = x; }
 * }
 */
class Solution {

    public void UpdateParent(TreeNode Parent, TreeNode Current, HashMap<TreeNode, TreeNode> map) {
        if (Current == null) {
            return;
        }
        map.put(Current, Parent);

        UpdateParent(Current, Current.left, map);
        UpdateParent(Current, Current.right, map);
    }

    public void Traversal(int distance, TreeNode node, HashMap<TreeNode, TreeNode> map, List<Integer> list,HashSet<TreeNode> set) {
        if (node == null) {
            return;
        }
        if (set.contains(node)) {
            return;
        }
        set.add(node);

        if (distance == 0) {
            list.add(node.val);
            return;
        }
        Traversal(distance - 1, node.left, map, list, set);
        Traversal(distance - 1, node.right, map, list, set);
        Traversal(distance - 1, map.get(node), map, list, set);

    }

    public List<Integer> distanceK(TreeNode root, TreeNode target, int k) {
        HashMap<TreeNode, TreeNode> map = new HashMap<>();
        HashSet<TreeNode> set = new HashSet<>();
        List<Integer> list = new ArrayList<>();
        UpdateParent(null, root, map);
        Traversal(k, target, map, list, set);
        return list;
    }
}

Title: What's New in React 18: Introducing createRoot
Published: 2023-09-16 04:41:55

Introduction:
React, the popular JavaScript library for building user interfaces, has introduced a game-changing feature in its latest version, React 18. Say hello to createRoot, a powerful tool that makes your React apps faster and more efficient. In this blog post, we'll explore what createRoot is, why it was introduced, and when you might need it.

What is createRoot?
At its core, createRoot is a new way to render React components into a web page. It's like a fresh approach to handling the rendering of your app. With createRoot, you can enjoy several benefits that weren't available with the older ReactDOM.render() method.

Automatic Batching for Efficiency:
Imagine you have a basket, and you're collecting updates to your web page in it. createRoot automatically groups these updates together and applies them all at once. This is like making a single trip to the store instead of going back and forth multiple times. The result? Your app becomes faster because it reduces the number of times it has to update the web page. Automatic batching is one of the standout features of createRoot.

Here's how you can use createRoot:

`

```
import { createRoot } from 'react-dom';

const root = createRoot(document.getElementById('root'));

root.render(<App />);`
```
Suspense for Smooth Loading:
Another exciting feature of createRoot is its support for "Suspense." Think of Suspense as a way to load data without making your app feel slow. It's like telling your app, "Hold on, I'm getting some information, but I won't freeze the whole app while I do it." This makes your app feel more responsive and user-friendly.

Here's an example of using Suspense with createRoot:


```
import { createRoot, Suspense } from 'react-dom';

const root = createRoot(document.getElementById('root'));

root.render(
  <Suspense fallback={<LoadingSpinner />}>
    <App />
  </Suspense>
);
```
Concurrent Rendering for Multitasking:
createRoot enables concurrent rendering, which is like turning your React app into a multitasking superhero. It can work on multiple tasks at the same time, which is especially helpful for complex apps. Your app becomes more responsive, and tasks are completed faster.

When Do You Need createRoot?
Now that you know what createRoot does, when should you consider using it?

If you want to make your app faster and more efficient, createRoot is your ally.
If you're using Suspense to load data without slowing down your app's performance.
If you want to take advantage of automatic batching to update your web page more efficiently.
Conclusion:
React 18's createRoot is a game-changer for building efficient and responsive web applications. It simplifies the process of rendering components, introduces automatic batching, supports Suspense for smoother loading, and enables concurrent rendering for multitasking. If you're looking to supercharge your React app, createRoot is a tool you should definitely explore.

Stay tuned for more updates and tutorials as React 18 continues to shape the future of web development.
