VLSI stands for Very Large Scale Integration. Generally there are substantially 2 types of VLSI systems – 1. systems in VLSI grounded System Design, 2. VLSI Design systems. You might be confused to understand the difference between these 2 types of systems. Let me now explain to you.

Systems in VLSI grounded system design are the systems which involve the design of varied types of digital systems that can be enforced on a PLD device like a FPGA or a CPLD.

The systems which deal with the semiconductor design are called as systems in VLSI design. These are veritably delicate and precious to apply in real time.
 
Top 5 VLSI Projects for ECE
- Bluetooth Based Wireless Home Automation System.
- FPGA Based Robotic ARM Controller.
- Cloud based temperature Monitoring system using IOT.

Advantages of using typed useSelector hook
Tags: react, redux, typescript
Published: 2022-08-17 10:14:00

One of advantages of using  typescript are that it reduces the risk of Bugged Code and  more Information/Documentation in Your Codebase. In order to fully embrace these cool features in our react application when using redux we have to use typed react-redux hooks. In this article we are going to explore how we can perform typing on `useSelector` hook.

When using typed useSelector hook our editor is able to detect properties that are associated with our redux central state.

In order to achieve this we have create a custom hook let's name is `useTypedSelector`. But before we jump in and implement this cool hook we have to first make some adjustment.

Before we create this hook we have to first determine the type of our redux state i.e properties of the central state. To achieve this we have to perform the following step: 

```
// import all reducers
import {combineReducers, createStore, applyMiddleware} from "redux";
// combine reducers
const reducer = combineReducers({});
export const store =createStore(reducer);
export type RootState = ReturnType<typeof reducer>;
```
In order to annotate typed useSelector hook we need RootState which represent the type of our redux central state. 

So in order to implement our custom typed useSelector hook we need `TypedUseSelectorHook` interface from `react-redux` and our `RootState` for annotation.

```
import {useSelector, TypedUseSelectorHook}  from "react-redux";
import {RootState} from "../state";

export const useTypedSelector: TypedUseSelectorHook<RootState> = useSelector;
```

After this, then we can go on and  use this hook to select slices of our state we need to use.
Understanding Excess Property Checking in Typescript
Tags: typescript, webdev, javascript, node
Published: 2022-08-17 09:06:00

**_This post was first posted in my newsletter [All Things Typescript](https://www.allthingstypescript.dev/) focused on teaching developers how to build better mental models around Typescript and its typing system. Please subscribe to start learning and mastering Typescript_**

Excess property checking is when Typescript checks your object to ensure that it doesn’t contain any extra properties on top of what is defined in the type annotation for the object.

Typescript doesn’t always check for excess properties in an object. Understanding when Typescript will check for excess properties is crucial as it helps you know what to expect from Typescript under different conditions.

Let’s start with the following type:

```ts
type Person {
  firstName: string;
  lastName: string;
}
```

If we created a new variable and typed it as Person, any excess properties in the object will be checked, and Typescript will throw an error.

```ts
const x: Person = {
  firstName: "John",
  lastName: "Doe",
  age: 13,`
}
```

In this case, you are going to get the following error:

![](https://substackcdn.com/image/fetch/w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fbucketeer-e05bbc84-baa3-437e-9518-adb32be77984.s3.amazonaws.com%2Fpublic%2Fimages%2F89577ee2-25bf-4b9d-9307-c78ab759fe58_915x272.png)

Type '{ firstName: string; lastName: string; age: number; }' is not assignable to type 'Person'. Object literal may only specify known properties, and 'age' does not exist in type 'Person'

  
And this makes sense and is expected because our type `Person` doesn’t contain the `age` property.

But, there are some situations where Typescript will remain silent when excess properties are available in an object.

Let’s explore which situations are those.

The first situation is when you introduce an object with the excess fields and assign it to a variable typed as `Person`.

```ts
const x = {
  firstName: "John",
  lastName: "Doe",
  age: 13,`
}

const y: Person = x;
```

In this case, Typescript won’t check for excess properties as type `Person` is a subset of the type inferred for variable `x`, which is inferred to include all properties in `Person` plus `age`. This is known as **duck-typing or structural typing**, which I will look at later.

> "If it walks like a duck and it quacks like a duck, then it must be a duck"

And in the second situation, when you use an assertion, this doesn’t trigger excess property checking in Typescript.

```ts
const x = {
 firstName: "John",
 lastName: "Doe",
 age: 13,
} as Person;
```

#### Conclusion

To recap, excess property checking is only triggered when we define object literals with a type annotation and not in other cases. So, why do we have it? It can be very useful for catching wrong typos and wrong property names. This means it’s very limited in scope and understanding when Typescript will check for excess properties and when it will not is essential for building a better mental model for understanding and using Typescript.
How to implement Lazy Loading in REACT | code splitting
Tags: react, javascript, webdev, programming
Published: 2022-08-17 09:35:00

Here is a simple App component: 

```
import Bids from './components/Pages/OnlineAuction/Auctions/Bids'
import { GeneralGoods } from './components/Pages/Galleries/GeneralGoods/GeneralGoods'

class App extends Component {
  render() {
    return (
    <div>
      <BrowserRouter>
      <div>
        <Routes>
       
            <Route path="/galleries-general-goods" element={<GeneralGoods />} />
           
        </Routes>
      </div>
      </BrowserRouter>
      </div>
    );
  }
}

export default App;
```

React imports all the components as soon as the Application starts. But there's a problem to this.

React takes some time to load all components and the App is accessible only after all the components have been imported.
So if a user to your site or app does not visit 7 out of 8 of your components, they will still be loaded and this has an impact on the performance of your app.

Luckily, there is a solution made available to us by REACT. 

**Lazy Loading**
We can choose when to load the required components. So components are only imported by REACT App only when the relevant route is visited.

Below are the 5 simple steps to achieve this:
1- Import Lazy & Suspense from REACT.

```
import {lazy, Suspense} from 'react'
```

2- Use the import function

```
const myComponent = () => import('./components/myComponent')
```

3- Wrap your imports in lazy()

```
const myComponent = lazy (() => 
import('./components/myComponent'))
```

4- Wrap the returns inside Suspense()

```
function App() {
    return (
      <Suspense>
        //ALL YOUR RETURN COMPONENTS HERE
      </Suspense>
)
}
```

5- Specify fallback for Suspense()

```
<Suspense fallback={<div><p>I am Loading</p></div>}
    //ALL YOUR RETURN COMPONENTS HERE
</Suspense>
```

Complete component should be something like this:

```
import {lazy, Suspense} from 'react'
import {Switch, Route} from 'react-router-dom'
const Bids = lazy(() => import('./components/Bids'))
const GeneralGoods = lazy(() => import('./components/GeneralGoods'))

function App() {
    return (
      <Suspense fallback={<div><p>I am Loading</p></div>} >
<Switch>
       <Route path="/bids" exact>
         <Bids />
       </Route>
       <Route path="/goods" exact>
         <GeneralGoods />
      </Route>
</Switch>

       </Suspense>
   )

}
```

How to create a backup of distro from WSL2
Tags: wsl, wsl2, backup, ubuntu
Published: 2022-08-17 09:32:00

Create a new backup of one distro from WSL2 on Windows is very simple. You simply need open a new powershell and run the command bellow:

```
 wsl --export Ubuntu-20.04 'C:\Backup-wsl\Bkp_Ubuntu-20.04'
```

Obviously, you can use the command to make the backup from another distro, and/or to another file. (Ex: `wsl --export {your_distro} '{your_path}'`)

**Note:** To make the backup, the Windows can stop your distro.
JavaScript (ES6) data Type
Tags: javascript, webdev, beginners, programming
Published: 2022-08-17 09:30:00

Hello everyone, welcome to the second blog of the beginner series. 
In previous blog we talked about DOM method, today we will be discussing basics on Data types.
**

## 
what is data type?
**
Data type describe the different types or kinds of data that we are gonna be working with and how things are stored. In javascript, there are 6 data types:

- String type
- Boolean type.
- Null type.
- Undefined type.
- BigInt type.
- Symbol type
**

## String:
**
A string is a series of characters like "Harry".  Also it could be a single character, a line of text, a paragraph, and so on. In javaScript there is no difference between single quotes and double quotes. You can use quotes inside a string, as long as they don't match the quotes surrounding the string.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/zgku1rfao0eix5sogbr8.png)
**

## Boolean Type:
**
In programming there is only two type of values, like 

- True or False
- yes or No.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/k00kouh9t6fn2d8kjs2g.png)
**

## Null type :
**
JavaScript Null value represent the international absence of any object value.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/wrh0fqqd4nb9jiu2b6cz.png)
**

## Undefined type:
**
A variable without a value defined has the value undefined. This is not similar as Null. 

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/fgaue8p2q4tgaxsije8v.png)
**

## BigInt type :
**
BigInt is a built-in object in javaScript. It's a primitive wrapper object used to represent and manipulate primitive BigInt values which are too large to be represented by the number primitive.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/wtysa2wwo8isfs1pdszh.png)
**

## Symbol type :
** 
A symbol represents a unique identifier. we can create many symbols with the exactly the same description, but they are different values. Symbols are must be unique.

PROGRAMMING AND YOUR MOVIES
Tags: webdev, programming, beginners
Published: 2022-08-17 09:25:43

I know you were thinking programming is as simple as what you see in series and movies.

Programming is nothing like what they show in Hollywood movies.

Movies usually show someone sitting in front of a laptop, typing like their fingers are on fire, and then everything magically works.


![Hacker Playing around the computer like in movies](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/42rs5hcr0rhcf13x14zk.gif)

This is why so many people have imposter syndrome, they never feel they know how to code, even though they’ve been programming for a long time.

The way coding is portrayed in the media is why you always feel and think other people know more than you do and in the real sense you are a badass developer.

Programming is, actually, a lot of searching for solutions and asking questions.

Programming is also hard sometimes put that in mind.

A lot of programming is looking up stuff that works for others online, and then transmuting it and taking it and applying it to YOUR project. well done boss you tried well.

Most people, when they run into a problem, they just give up. I was this before, I don't like many challenges and dislike testing out so as not to disrupt what I have.

They'll either ask somebody for an answer, or give up, and then they'll go, "Okay, this project is too hard. I can't do it.

Nope. You need to Google the 💩 out of it.

I promise you the answer is somewhere lurking on GitHub, on Stack Overflow, on a blog far away on page 15 of your search, or in a YouTube tutorial.

You could watch the tutorial and see how they implemented this one feature in their own project. You could take it and then try to implement it into your own project.

It's an incredible ability to have, and the way you develop it is by persevering through a problem and sticking through all the way to the end. 👊.

If you see me code a project, it's not going to be as exciting as you think it is.

I'm not just going to be sitting there and just coding it from scratch. 😴

I'll be looking up stuff, I'll be pulling pieces of code (pull stack developer😊), I'll be trying to think of things, I'll think of ideas... and then I'll keep moving on. 🚀

![Control C gif](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/gs67yxa7vocemuocrt6y.gif)

Just so you know:

You are good at what you do and you can break the limits. Also, know that you could have imposter syndrome and still be incompetent....

That's how you code and overcome imposter syndrome 💯
