Published: 2024-03-09 21:30:00

I've never used a tool more powerful than this ever before.

It took me less than 2 minutes to generate:

✅ SaaS Dashboard UI
✅ Checkout section for an e-commerce site
✅ and literally anything else

You can even modify parts of the code!

Wanna take a look into what it is?

Before that, take a look at these:

{% embed https://twitter.com/mustafaergisi/status/1731726948034846907 %}

***

### About This Awesome Tool 👇

[v0](https://v0.dev/) is a generative user interface system by Vercel Labs powered by AI.

It generates copy-and-paste friendly React code based on shadcn/ui and Tailwind CSS that people can use in their projects.

It also supports "Screenshot to Code" which makes it even more powerful.

Here’s how it works:

1️⃣ Describe the interface you want to build
2️⃣ v0 produces code using open-source tools like React, Tailwind CSS, and Shadcn UI
3️⃣ Select an iteration and keep editing in v0
4️⃣ When you're ready, copy and paste that code into your app and develop from there

***

### v0's Powers 🔥

Imagine you want to create a new website, but you don’t have any experience with coding.

With v0, you can describe the user interface you want in plain text, and v0 will generate the necessary React code.

For example, you could say:

> _A landing page hero section with a heading, leading text and an opt-in form._

Here's what it will give you:

![Image](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/paia3ayyaxe4w4jilx3z.png)

For the source code of the component: click the "Code" button

![Image](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/zrbovrl1szr6dn2053rg.png)

You can also prompt it to modify some parts of the component with this text box

![Image](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/bnfzo6d3p0l98i9jedyw.png)

I asked it to "add a gradient to the background with a slight blur" and here's what it gave me:

### Final Thoughts 🙌

Again, the classic question arises: **Will this be the end of frontend developers?**

According to me, til the foreseeable future, No.

But yes, it will make UI development a bit too easy.

Arrow Funcion In javascript

[](https://youtu.be/TUzDpvm3BOk?feature=shared)
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/8fpnjmr3jkymenki55fv.png)**
## **First we need tho understand what is function**
**
**[Function](https://youtu.be/otz_EQ3z1HA?si=suKrtdJzfRbHGHyV)**- It is Block of statement  which take input as parameter and perform some operation on that input and return them as output.
**
## **Syntax of  Normal Function **
**
`function HelloWorld()// function defintion
{
  console.log("Hii")
}
HelloWorld();// function calling`
Now, we need to understand 
**--What is Arrow Function??**
**Arrow Function**-{()=>}-concise way of writing javascript function in shorter way.
Introduced in ES6 version.It is anonymous function without a name.
  **Syntax of  Normal Arrow Function**

`const hello=()=>
{
  console.log("hello world");
}
hello();
`
**[Arrow Function with parameters](https://youtu.be/TUzDpvm3BOk?feature=shared)**
`const add=(a,b)=>
{
return a+b;
}
console.log(add(2,3))`
**Simpler way of writing Arrow Function**
`const diff=(a,b)=>a-b;
console.log(diff(2,1))`

**Note :- arguments keyword are not available in arrow function.**

**Spread Operator in arrow Function**

`const Number=(...num)=> console.log(num)
Number(2,3,4,5,10) // [2,3,4,5,10]`

First we need to understand **what is Hoisting in javascript** so calling a function before defining it Known as  Function Hoisting.
It does not give any difference in normal function for ex
`multiply(3,2))//6
function multiply(a,b)
{
 console.log(a*b);
}`
But is not allowed in arrow function it will show error.

before , discussing this keyword in arrow function let's see the working of this keyword in normal function declared inside object.

`const obj=
{
  name:'Radhika',
  myFunction: function()
{
  console.log(this.name)
},
};
obj.myFunction// 'Radhika'`

Here , in above code this keyword is working for this object only but if we declare this keyword inside arrow function it will show value as undefined let see the code of it.

```
const obj=
{
  value:20,
  myFunction: ()=>
{
  console.log(this.value)
},
};
obj.myFunction()// undefined `


the reason behind is this that this keyword inside arrow function work for window not for that object inside which it is declared in case of arrow function.

Cracking the Code: Exploring Key Components in Kubernetes YAML
Tags: kubernetes, cncf, cloudnative, devops
Published: 2024-03-09 20:02:28


In the realm of Kubernetes, YAML files serve as blueprints for deploying and managing various resources. Among these resources, the pod stands out as a fundamental building block. In this guide, we'll delve into the key components of a pod definition YAML file, shedding light on each element's significance and role in the Kubernetes ecosystem.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/gb2jou8zl5qnf7ws59nk.jpg)

A typical Kubernetes YAML file looks like this:

```
apiVersion: v1
kind: Pod
metadata:
  name: mypod
spec:
  containers:
  - name: nginx
    image: nginx:latest
    ports:
    - containerPort: 80

```

Let's explore a few of the components of the Kubernetes YAML file.

1: **apiVersion**: 
The apiVersion field in a Kubernetes Pod definition YAML file specifies the version of the Kubernetes API being used. Typically, it's set to "v1" for most use cases. However, depending on the resource being created (such as a deployment or service), the value may vary. For instance, when creating a deployment, the apiVersion might be "apps/v1".

2: **kind** :
The kind field defines the type of Kubernetes object or resource being created. In the context of pods, the value would be "Pod". However, Kubernetes supports various resources, so the kind can vary accordingly. For example, for a Deployment, the kind would be "Deployment".

3: **metadata** :
It basically contains metadata about the Kubernetes resource, such as name, labels, and annotations.

4: **spec** :
The spec (specifications) section provides additional details about the resource being defined. For pods, the spec includes essential parameters like container names, container images, ports, and more. Each Kubernetes resource has its own specific set of specifications outlined in its documentation, ensuring flexibility and customisation.

These are the fundamental components you'll find in most Kubernetes YAML files. Depending on the resource type, additional fields or sections may be required or optional, like selectors, volumes, initContainers, etc.

**Conclusion**:
Understanding the structure of a Pod Definition YAML file is fundamental for managing Kubernetes resources effectively. Keep experimenting and exploring Kubernetes documentation to deepen your understanding and proficiency with Kubernetes manifests.

****Q2. Suppose you are a software tester and you are assigned to test a new mobile app that has just been developed. The app has three different user roles: basic user, premium user, and admin user. You have been given the following three test scenarios to execute:****

1)Basic users can only access limited features of the app, while premium users can access all features. Admin users have access to advanced settings and can perform all actions.

2)Users should be able to create and delete their accounts successfully. Passwords must meet the required complexity standards and users should receive a conformation email upon successful account creation.

3)Users should be able to navigate through the app seamlessly without any crashes or performance issues. The app should also display appropriate error messages when a user attempts to perform an action they are not authorized to perform.

For each of the test scenarios, describe the steps you would take to test them and the expected results.

ChatGPT is my Pair Programming Partner
Tags: programming, python, productivity, chatgpt
Published: 2024-03-09 18:53:25

I've developed a dozens of Python projects that are implemented or hosted on Raspberry Pis or Lightsail servers. My Pi projects are predominately **internet of things** applications using many sensor and components from **Adafruit**. The AWS Lightsail applications are all Django projects. I've also developed a couple of Django web servers on Pis. 

When I've encountered problems - syntax or logic - I've relied heavily on the Dev and open source community. I can't count the number of times I've searched StackOverflow or GitHub for a solution to my current problem. **Thank you!**

The downside is that my typical searching effort has been pretty time consuming and somewhat hit or miss. 

Now, my first stop is **ChatGPT** to get help and the experience has been amazing. ChatGPT provides great examples and I can tailor the responses to make it almost a cut-n-paste solution! I now have a pair programming partner that is a language lawyer, tester and strong developer! 

_I highly recommend adding ChatGPT to your development toolkit_.
Want to prevent Model Overfitting?
Tags: machinelearning, deeplearning, datascience, learning
Published: 2024-03-09 18:32:47

Five different techniques to prevent overfitting:
- Early Stopping: In this method, we track the loss on the validation set during the training phase and use it to determine when to stop training such that the model is accurate but not overfitting.

- Image Augmentation: Artificially boosting the number of images in our training set by applying random image transformations to the existing images in the training set.

- Dropout: Removing a random selection of a fixed number of neurons in a neural network during training.

- Increase dataset size: The more training data you feed, the less likely it is to overfit. The reason is that, as you add more data, the model cannot overfit all the samples, and is forced to generalize to make progress.

- Regularization: Regularization is a method to constrain the model to fit our data accurately and not overfit. It can also be thought of as penalizing unnecessary complexity in our model


Did I miss anything?🤔 Let me know in the comments. Happy Learning.😊
Deploying Go To AWS using CDK in 2024
Tags: go, aws, errors, lambda
Published: 2024-03-09 18:09:06

With go.1x being a deprecated runtime in AWS, we need to start using the `PROVIDED_AL2023` runtime. There are quite a few tutorials out there that go over deploying Go lambdas, so I wont cover the extreme detail. (I followed this one by Melkey btw ;)) This is meant to fill in the gap if you are getting this pesky error at runtime:

```shell
Error: Couldn't find valid bootstrap(s): [/var/task/bootstrap /opt/bootstrap]
```

Let's say you have a lambda function defined like this with CDK:
```typescript
const myTestFunction = new lambda.Function(this, "myTestFunction", {
      // This points to where your Go lambda lives
      code: lambda.Code.fromAsset("lambdas"),
      handler: "main",
      runtime: lambda.Runtime.PROVIDED_AL2023 // Because GO_1_X is now deprecated
    });
```
(this is also assuming your file structure follows Melkey's video)

If you were to just build your lambda like this: 
```shell
GOOS=linux GOARCH=amd64 go build -o main
```
You will encounter the pesky bootstrap error. This is because AWS lambda looks for a bootstrap in the folder that you defined in your code block.

Simply change the out file to `bootstrap`

```shell
GOOS=linux GOARCH=amd64 go build -o bootstrap 
```

AWS Lambda will now be able to see your built Go function and your function will be invoked properly.

There might be better ways to do this, but currently I'm new to Go and this worked for me! Hopefully this helps someone out!
