Beyond Web 2.0: Exploring the Benefits and Opportunities of Web 3.0's Decentralized Future
Published: 2023-04-28 18:49:05

## **Introduction**
As the internet has evolved, so has the way we interact with it. The first iteration of the web, known as Web 1.0, was primarily static and focused on providing information. With the introduction of Web 2.0, the internet became more interactive, allowing users to contribute content and engage with others. Now, we stand on the precipice of another major shift in the way we use the internet, as Web 3.0 comes into focus.

Web 3.0 is the next generation of the internet, built on decentralized systems and utilizing blockchain technology. This new web promises to transform the way we interact with each other and the world around us, and there are several compelling reasons why you should consider transitioning from Web 2.0 to Web 3.0:

1.) **Decentralization**: One of the most significant differences between Web 2.0 and Web 3.0 is the move towards decentralization. With Web 2.0, content is created and controlled by a small number of powerful corporations. Web 3.0, on the other hand, allows for the creation and distribution of content to be in the hands of a decentralized community. This decentralized structure makes the internet more resilient and less vulnerable to censorship, manipulation, and other forms of control.

2.) **Security**: With Web 3.0, security is built into the system from the ground up. By utilizing blockchain technology, Web 3.0 ensures that data is secure and cannot be easily tampered with. This is particularly important given the rise of cybercrime and data breaches in recent years.

3.)**Privacy**: Web 2.0 has been criticized for its lack of privacy protections. With Web 3.0, users have greater control over their data and can decide who has access to it. This increased privacy is achieved through the use of decentralized identity solutions that allow users to control their own identity and data.

4.)**Interoperability**: Web 3.0 allows for greater interoperability between different applications and systems. This means that data can be easily shared between different platforms, enabling greater collaboration and innovation.

5.)**Micropayments**: Web 3.0 introduces the concept of micropayments, which allows for transactions as small as a few cents to be made easily and securely. This opens up new revenue streams for content creators and other participants in the decentralized ecosystem.

## **Conslusion**
In conclusion, the transition from Web 2.0 to Web 3.0 represents a fundamental shift in the way we use the internet. By embracing decentralization, security, privacy, interoperability and micropayments. Web 3.0 promises to create a more open, inclusive, and decentralized internet that is resistant to censorship and manipulation. As Web 3.0 continues to evolve, it will be exciting to see the new applications and possibilities that emerge.
Predicate Functions

Published: 2023-04-28 18:47:50

In the world of graph databases, predicates are essential for filtering and refining query results. Predicates are boolean functions that evaluate input data and return true or false, depending on whether the input meets certain criteria. In this blog post, we'll take a closer look at two types of predicates - exists() with a property argument and exists() with a path argument.

## exists() with a property argument:

The exists() function with a property argument returns true if the specified property exists in the node, relationship, or map. It is different from the EXISTS clause, which is used to check the existence of a subquery result. The exists() function is typically used to filter out subgraphs in the WHERE part of a query.

The syntax for using exists() with a property argument is as follows:

```
exists(property)
```

Here's an example of how to use exists() with a property argument:

```
SELECT *
FROM cypher('graph_name', $$
     MATCH (n)
     WHERE exists(n.surname)
     RETURN n.first_name, n.last_name
$$) as (first_name agtype, last_name agtype);
```

This query returns all nodes that have a surname property, along with their first_name and last_name values.

## exists() with a path argument:
The exists() function with a path argument returns true if there already exists the given path in the graph. This predicate is useful for filtering nodes that are connected to a specific node through a given path.

The syntax for using exists() with a path argument is as follows:

```
exists(path)
```

Here's an example of how to use exists() with a path argument:

```
SELECT *
FROM cypher('graph_name', $$
     MATCH (n)
     WHERE exists(n)-[]-(name: 'Willem Defoe')
     RETURN n.full_name
$$) as (full_name agtype);
```

This query returns all nodes that have a path to a node with the name property equal to 'Willem Defoe', along with their full_name values.

## Conclusion:
In conclusion, predicates are a powerful tool for filtering and refining query results in graph databases. Whether you're using exists() with a property argument or exists() with a path argument, understanding how these predicates work can help you write more efficient and effective queries.
Understanding how React handles state updates.
Tags: react, javascript, webdev
Published: 2023-04-28 18:29:21

As someone who has experienced being a new JavaScript developer and attempted to learn React after grasping the fundamentals of state and its management at the component level, I've noticed that confusion can arise regarding the synchronicity of the state setter returned by the useState hook. In this situation, My objective is to offer a brief explanation of how React manages state updates.

Consider this code snippet:

```
function App() {
  const [count, setCount] = useState(0);

  const onClickHandler = () => {
    setCount(count + 1);
  };

  return (
    <div className="App">
      <h3>{count}</h3>
      <button onClick={onClickHandler}>Increment</button>
    </div>
  );
}
```

In the above scenario, what can be inferred is that, on click of the button, the setCount will increment the state count by 1. Pretty straight forward.

Now consider the following change in the above code:

```
function App() {
  const [count, setCount] = useState(0);

  const onClickHandler = () => {
    for (let i = 0; i < 100; i++) {
      setCount(count + 1); 
    }
  };

  return (
    <div className="App">
      <h3>{count}</h3>
      <button onClick={onClickHandler}>Increment</button>
    </div>
  );
}
```

In this scenario, you will see that essentially the state updates just once and count value becomes 1 on a single click.

To understand what just happened, we would have to understand how state updates are characterised in React. Primarily, they are **not asynchronous**. But what makes them a bit peculiar than other synchronous functions is that **state updates in React are scheduled in a Queue**. Now, React updates the state, hence causing a re-rendering of the view if needed, but updates are committed on its own whims to enhance rendering performance. React may delay it, and then update several components in a batch. So essentially in the above component, the entire for loop runs adding a bunch of state updates in the queue but what matters is that the count value inside setCount(count + 1) is still 0, which means referencing the state right after updating it is pitfall to be avoided at all cost. Upon encountering the last setCount, the value of count is still 0 and hence it's incremented.

Now there is another way to reference current state inside a state update method:

```
function App() {
  const [count, setCount] = useState(0);
  console.log("Rendered");
  const onClickHandler = () => {
    for (let i = 0; i < 100; i++) {
      setCount((currCount) => currCount + 1);
    }
  };

  return (
    <div className="App">
      <h3>{count}</h3>
      <button onClick={onClickHandler}>Increment</button>
    </div>
  );
}
```

What will be observed is in this case we will see the state of count updated to 100 on a single click. The reason being the added callback is going to be executed post the previously scheduled state update and in process providing the updated state value.

Hope reading through this article helped you get a fresh perspective to React state updates.
Destructuring props in React
Tags: beginners, react, codenewbie, discuss
Published: 2023-04-28 18:14:30

As with everything in coding, there is usually more than one way to reach the same outcome. Sometimes it's about best practice, but often times it comes down to personal preference.

_Destructuring props is no exception to this._

## What is a prop?

In React, "props" is a shorthand for properties, which are used to pass down data and functions from parent components to child components. Destructuring those props is a way to extract values from objects or arrays and assign them to variables.

## Version One


Here's an example of destructuring props in the child component:

```

function MyComponent(props) {
  return (
    <div>
      <h1>{props.prop1}</h1>
      <p>{props.prop2}</p>
    </div>
  );
}

```
In the example above, we extract prop1 and prop2 from props using destructuring, and then use them in the component's return.

This is helpful when you are passing down multiple functions and states, since the passed down prop will get pretty lengthy. This issue I find is that I tend to have to look back at the parent component to see exactly what I passed down and need to utilize.

## Version 2

Here's an example of destructuring props as you pass them down:

```

function MyComponent({prop1, prop2}) {
  return (
    <div>
      <h1>{prop1}</h1>
      <p>{prop2}</p>
    </div>
  );
}

```
In the example above, the component MyComponent takes an object as its argument, which contains two properties: prop1 and prop2. Instead of using props.prop1 and props.prop2, we can use destructuring to extract the values of these properties and assign them to variables of the same name.

I find this beneficial to be able to visualize everything I am passing down in one statement, so I know what I have used.

## So which is better?


In both examples, destructuring props allows us to use the properties directly without needing to reference them via the props object. This can make the code more readable and concise. At the end of the day, it comes down to personal preference, since both of these options will give you the same results.

Which do you prefer?
Price's Law: My Path to Becoming an Overperforming Wizard
Published: 2023-04-28 18:14:28

If you're a software developer, chances are you've heard of Price's Law. But what does it really mean, and why does it matter? Simply put, Price's Law states that in any given field, the square root of the number of people in that field will produce half of the output. 

So for example, for a company of 16 people, 50% of the work is done by 4 engineers.
For a team of 100 people, 10 engineers do half the work. 
For a project of 10,000 people, 100 do half the work.

A small number of top performers are responsible for the majority of the work.

Looking at popular open source projects we see just how true Price's Law is. A study of the top 1000 contributors to the Linux kernel found that just 10% of them were responsible for over 80% of the code contributions. Similarly, a study of the top 1000 contributors to the Apache Hadoop project found that just 11% of them were responsible for over 90% of the code contributions.

As a software developer, I really fancy being one of these overperforming wizards. You know, the guys who seem to effortlessly crank out code that is miles ahead of everyone else's. The ones who push the boundaries of what is possible and leave their mark on the industry.

These numbers are staggering, and they show just how important it is to strive to be one of the top performers in our field. The question is, can anyone become an overperforming wizard, or are they just born that way?

While there is no clear-cut answer, for me, I am constantly pushing myself to learn new skills and take on challenging projects. It means seeking out mentorship and guidance, and being willing to put in the extra time and effort to produce high-quality work.

But it's not just about hard work. It's also about having a passion for software development and a DEEP understanding of the underlying technologies. Take George Hotz, for example. He became famous in the early 2000s for jailbreaking the iPhone and developing a self-driving car. His success was due in part to his incredible coding skills, but also to his deep understanding of the inner workings of technology.

Or take Michael Carmichael, another top performer in the field of software development. Carmichael is the founder of the popular open source project, the SaltStack configuration management system. His success is due to his deep knowledge of software development and his ability to build a community of contributors around his project.

The bottom line is, becoming an overperforming wizard in software development is possible, but it takes a lot of hard work, dedication, and passion. Anime has taught me that while not everyone may be born with the natural ability to excel in this field, anyone can improve their skills with practice and dedication. 

I really wonder if I will ever be one of the greats. At least by my own standards.
Browser Workflow in Bangla
Published: 2023-04-28 17:09:05

React JS এর ক্ষেত্রে আমরা বারবারই একটা fancy word শুনে থাকি, সেটা হলো Virtual DOM! যে myth টা মানুষের মধ্যে ঢুকে আছে সেটা হলো - Virtual DOM, আমাদের চির পরিচিত browser DOM এর থেকে অনেক fast এবং একারণে vanilla DOM এর থেকে React অনেক fast User Interface Render করে! আসলেই কি তাই? React কি শুধুই Performance achieve করার জন্যই Virtual DOM use করে?

আমরা শুনে থাকি DOM(document object model) টা slow and inefficient । কিন্তু এটা টিক না ।

react এর dom এর ক্ষেত্রে বলা হয় এটা dom(document object model ) এর চেয়ে বেশি efficient and fast way তে view render করতে পারে ।

_*we will discuss here why reactDOM faster and efficent.
what is vartual dom
why we will choose react *_

## DOM কি আসলেই slow ?

React JS এর ক্ষেত্রে আমরা বারবারই একটা fancy word শুনে থাকি, সেটা হলো Virtual DOM! যে myth টা মানুষের মধ্যে ঢুকে আছে সেটা হলো - Virtual DOM, আমাদের চির পরিচিত browser DOM এর থেকে অনেক fast। কথাটা সম্পর্ন ভুল ।

truth is DOM আসলে যতয়েষ্ট fast । dom theke কোন element add or রিমুভ করা simple একটা জাভাস্ক্রীপ্ট object এ property set করার মতো ।

যে process টা slow তা হল dom change হওয়ার পরে আমাদের চোখের সামনে সেটাকে দেখানোর জন্যে browser কে যে কাজটা করতে হয় সেই
process টা slow

সেটা বুজতে হলে আমাদের ব্রাউজার এর workflow টা বুজতে হবে

## browser workflow

1. browser যখন html file receive করে ব্রাউজার এর render enginee সেটাকে parse করে (html parse ) এবং একটা dom tree বানাই । dom tree তে সব html এলিমেন্ট এক এক টা node হিসাবে থাকে
   ![Screenshot 2023-04-28 210526](https://user-images.githubusercontent.com/48369328/235184188-3e5e9477-dfcc-49e1-bb1c-2f01df0075ee.png)

2. একই সাথে html এর সাথে যে css style গুলো এসেছিল সেগুলো আবার css parser এর কাছে যায় এবং সেটাকে parse করে document object (dom) এর মতো আর একটা model বানাই তাকে cssom বলে ![Screenshot 2023-04-28 211549](https://user-images.githubusercontent.com/48369328/235186814-acd7d2b2-4500-4526-bb65-fbb5ba4c58e5.png)

তাহলে dom হল html এর object model আর ccsom হল style এর অবজেক্ট মডেল ![Screenshot 2023-04-28 212147](https://user-images.githubusercontent.com/48369328/235188821-46dde417-d383-4a92-8f75-3f5707c80545.png)

3. এই parse css আর parse html মিলে আর একটা render tree নামে tree বানাই ![Screenshot 2023-04-28 213135](https://user-images.githubusercontent.com/48369328/235190632-c583ee42-d63c-4e51-b2c0-9fda1165d37a.png)
4. এই render tree কে layout নামের একটা prase এর মদ্যে দিয়ে যেতে হয় ![Screenshot 2023-04-28 214107](https://user-images.githubusercontent.com/48369328/235192812-14fa0acb-0671-4211-b740-2678588c9b80.png) এই layout prase এ প্রতিটা render tree র element এর coordinate হিসেব করে element গুলোর সাথে attatch হয়ে যায় যেন screen এর কোন জায়গায় actually সেটা print হবে সেটা সে বুজতে পারে ।
5. যেহেতু এখন render tree এর কাছে element আছে সেগুলোর style আছে এবং কোন জায়গায় print করতে হবে সেগুলোর coordinate আছে তাই এবার last prase painting এ paint বা print করে দেয় যাতে আমরা দেখতে পরি বা display করতে পরি!
