1,873,104 | How to Change User's Password in Django: A Friendly Guide | Hey there, Django developers! Whether you’re building a robust web application or a simple website,... | 0 | 2024-06-01T16:02:17 | https://dev.to/davidomisakin/how-to-change-users-password-in-django-a-friendly-guide-556l | Hey there, Django developers! Whether you’re building a robust web application or a simple website, user authentication is a crucial feature. One essential part of user authentication is allowing users to change their passwords. In this guide, I’ll walk you through how to implement a password change feature in Django. Let’s get started!
**Step 1**: Setting Up Your Django Project
```
pip install Django
```
Create a new Django project and app if you haven't already:
```
django-admin startproject myproject
cd myproject
django-admin startapp myapp
```
Don’t forget to add your app to the INSTALLED_APPS list in `myproject/settings.py`:
```
INSTALLED_APPS = [
...
'myapp',
]
```
**Step 2**: Adding URL Patterns
To enable password change functionality, we need to add some URL patterns. Create a urls.py file in 'myapp'.
Open myapp/urls.py and include the following:
```
from django.urls import path
from django.contrib.auth import views as auth_views
urlpatterns = [
path('password_change/', auth_views.PasswordChangeView.as_view(template_name='password_change.html'), name='password_change'),
path('password_change/done/', auth_views.PasswordChangeDoneView.as_view(template_name='password_change_done.html'), name='password_change_done'),
]
```
Make sure you also include `myapp.urls` in your main `myproject/urls.py`:
```
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('myapp.urls')),
]
```
**Step 3**: Creating Templates
Django’s built-in `PasswordChangeView `and `PasswordChangeDoneView `require templates to render the forms and success messages. Create a directory called `templates `inside your app folder, and then create two HTML files: `password_change.html` and `password_change_done.html`.
Here’s a basic example for `password_change.html`:
```
<!-- templates/password_change.html -->
{% extends "base.html" %}
{% block content %}
<h2>Change Password</h2>
<form method="post">
{% csrf_token %}
{{ form.as_p }}
<button type="submit">Change Password</button>
</form>
{% endblock %}
```
For password_change_done.html:
```
<!-- templates/password_change_done.html -->
{% extends "base.html" %}
{% block content %}
<h2>Password Change Successful</h2>
<p>Your password has been changed successfully!</p>
{% endblock %}
```
Step 4: Do not forget to update the templates directory in Settings
Ensure you have the following settings in myproject/settings.py to manage your templates and authentication:
```
# Template settings
TEMPLATES = [
{
...
'DIRS': [BASE_DIR / 'templates'],
...
},
]
# Authentication settings
LOGIN_URL = 'login'
LOGIN_REDIRECT_URL = 'home'
LOGOUT_REDIRECT_URL = 'login'
```
**Step 5**: Test the Password Change Functionality
Start your Django development server:
```
python manage.py runserver
```
Navigate to http://127.0.0.1:8000/password_change/ and you should see the password change form. Enter your current password, new password, and confirm the new password. If everything is set up correctly, you should be redirected to the password change success page.
**Conclusion**
And that’s it! You’ve successfully implemented a password change feature in your Django application. This feature enhances the security of your application by allowing users to update their passwords regularly.
Feel free to customize the templates and views to better fit your project’s design and functionality. If you have any questions or run into any issues, don’t hesitate to reach out. Happy coding!

1,873,091 | Enhancing Python Classes with Magic Methods: A Comprehensive Guide | Introduction: Magic methods, also known as ‘dunder’ methods, are a unique feature in... | 0 | 2024-06-01T16:01:42 | https://dev.to/christopherthai/enhancing-python-classes-with-magic-methods-a-comprehensive-guide-49ec | python, webdev, tutorial, learning | ##Introduction:##
Magic methods, also known as ‘dunder’ methods, are a unique feature in Python that can add a touch of ‘magic’ to your classes. These methods, surrounded by double underscores, are triggered by the Python interpreter under specific circumstances. Also, they enable classes to integrate seamlessly with fundamental Python operations. They can be used for various tasks, such as converting an object to a string or adding two objects together. For instance, the ‘str’ method can describe how an object should be represented as a string, and the ‘add’ method can define how two objects should be added together.
Python interpreters invoke these methods in specific scenarios. A typical example is the `__init__()` method, which initializes a new object, `__repr__()` and `__str__()`, which are used for representing the object as a string for developers and users, respectively. Through magic methods, Python allows objects to overload standard operations, a concept where an object can redefine how an operator or built-in function works with that object. This capability is a powerful tool that improves the code’s efficiency and functionality, ensuring that objects work with Python built-in functions effectively and intuitively.
This blog will explore how leveraging magic methods can improve the utility of custom classes, making them more versatile and robust than Python’s core types and promoting their deeper integration with the language’s features. This leads to more cleaner and maintainablity code and enables developers to implement advanced object-oriented designs that interact naturally with Python’s own structures.
##Understanding Magic Methods:##
Magic methods provide a way to define how your objects should interact with various aspects of Python, such as functions, statements, and operators. They are the mechanism behind the sense for many of Python’s built-in functionalities, and by defining these methods in your classes, you can leverage Python’s intuitive and concise styles.
##Essential Magic Methods and Their Implementations:##
###Constructor and Initializer: `__new__` and `__init__`###
* `__new__(cls, …):` Called to create a new instance of a class. `__new__` is rarely used but is essential for immutable or complex instances where you need to control the creation before initialization.
* `__init__(self, …):` Used to initialize a new object after it’s been created.
```
class Example:
# __new__ is a class method that is called before __init__
def __new__(cls):
print("Creating instance")
return super(Example, cls).__new__(cls) # super() returns the parent class
# __init__ is a instance method that is called after __new__
def __init__(self):
print("Initializing instance")
```
###String Representation: `__str__` and `__repr__`###
* `__str__(self):` Defines the user-friendly string representation of an object, and is used by the str() function and print.
* `__repr__(self):` Intended for developers, used for debugging and development, should be as explicit as possible and, if feasible, match the code necessary to recreate the object.
```
class Product:
def __init__(self, name, price):
self.name = name
self.price = price
__str__ is called by the str() built-in function and by the print statement
# It should return a string representation of the object
def __str__(self):
return f"{self.name} costs ${self.price}"
__repr__ is called by the repr() built-in function and is also used in the interactive console to display the object
def __repr__(self):
return f'Product("{self.name}", {self.price})'
```
###Arithmetic Operations: `__add__`, `__sub__`, etc.###
* Define behavior for all arithmetic operators `(+, , , /)`.
* `__add__(self, other):` Allows two objects to be added together using `+`.
```
class Vector:
def __init__(self, x, y):
self.x, self.y = x, y
# __add__ is called when the + operator is used.
# It should return a new object with the result of the operation (not modify the original object)
def __add__(self, other):
return Vector(self.x + other.x, self.y + other.y)
def __repr__(self):
return f"Vector({self.x}, {self.y})"
```
###Comparison Magic Methods: `__eq__`, `__lt__`, etc.###
* `__eq__(self, other):` Defines behavior for the equality operator `==`.
* Other comparison methods include `__ne__`, `__lt__`, `__le__`, `__gt__`, `__ge__`.
```
class Book:
def __init__(self, title, author):
self.title = title
self.author = author
# __eq__ is called when the == operator is used.
# It should return True if the objects are equal, False otherwise
def __eq__(self, other):
return self.title == other.title and self.author == other.author
```
###Container Methods: `__len__`, `__getitem__`, `__setitem__`, and `__delitem__`###
* These methods allow your objects to act like containers.
* `__len__(self):` Return the length of the container.
* `__getitem__(self, key):` Define behavior for accessing an item `(container[key])`.
* `__setitem__(self, key, value):` Define behavior for setting an item `(container[key] = value)`.
* `__delitem__(self, key):` Define behavior for deleting an item `(del container[key])`.
```
class SimpleDict:
def __init__(self):
self._items = {}
# __len__ is called by the len() built-in function
# It should return the length of the object
def __len__(self):
return len(self._items)
# __getitem__ is called when the object is accessed using the [] operator
# It should return the value associated with the key
def __getitem__(self, key):
return self._items.get(key, None)
# __setitem__ is called when the object is modified using the [] operator
# It should set the value associated with the key
def __setitem__(self, key, value):
self._items[key] = value
# __delitem__ is called when an item is deleted using the del statement
# It should delete the item associated with the key
def __delitem__(self, key):
if key in self._items:
del self._items[key]
```
###Practical Example: Creating a Complex Number Class with Magic Methods###
Let’s bring some of these concepts together by creating a class that represents complex numbers and uses several magic methods to allow mathematical operations and more:
```
class ComplexNumber:
# __init__ is called when the object is created
# It should initialize the object with the given real and imaginary parts
def __init__(self, real, imag):
self.real = real
self.imag = imag
# __add__ is called when the + operator is used.
# It should return a new object with the result of the operation (not modify the original object)
def __add__(self, other):
return ComplexNumber(self.real + other.real, self.imag + other.imag)
# __sub__ is called when the - operator is used.
# It should return a new object with the result of the operation (not modify the original object)
def __mul__(self, other):
return ComplexNumber(
self.real * other.real - self.imag * other.imag,
self.imag * other.real + self.real * other.imag,
)
# __str__ is called by the str() built-in function and by the print statement
def __repr__(self):
return f"{self.real} + {self.imag}i"
```
In this example, the **ComplexNmber** class allows additions and multiplication of complex numbers, integrating seamlessly with Python’s syntax.
##Conclusion:##
Magic methods are critical to Python programming, serving as a bridge that allows custom objects to emulate the behavior of bulti-in types. This feature enriches the language by offering to improve functionality and effortlessly integrate with Python’s core operations. When developers incorporate these unique methods, characterized by their double underscore prefixes and suffice, into their classes, they naturally empower their code to interact with basic Python operators and functions. This will result in more maintainable and intuitive codes, significantly improving the readability and performance of software applications. So, implementing magic methods can ensure that custom objects adhere to Pythong’s elegant syncs and thrive within its operational paradigm, thus elevating the overall programming experience.
##Further Exploration:##
The capabilities of magic methods extend far beyond what has been discussed in this blog. They provide a foundational framework that invites further experimentation and exploration. For instance, methods like `__enter__` and `__exit__` are crucial for context management, facilitating using the “with” statement to manage resources efficiently. Additionally, the `__call__` method can make an object callable, just like a function, which opens up creative possibilities for designing flexible and modular code. Exploring these and other magic methods can unlock advanced functionality and enable developers to create more sophisticated and robust systems within the Python environment. Engaging with these more profound aspects of Python’s object models can encourage a better utilization and understanding of the Python language’s extensive features, which can drive innovation and expertise in Python programming. | christopherthai |

All I understand, which I believe is fundamental to all these new architectures, is how you and your team maintain a code base, not in terms of “Clean Code,” but how you figure out that these many functionalities should belong to this or that module or component. It is a great observation to make when you finally understand that scaling is not always the solution to every problem that runs on a server and communicates via the network.
It is not trivial to convince people in tech that you may not have to rewrite the whole system because it is not coping with the traffic or the input. Start looking for places where you are doing expensive computes, and the logic may need some refactoring this time to get the same results. I have seen this in many projects where some pieces of code work as duct tape and now when we bring the whole system to play in the field, the tape is starting to widen open sooner or later. And I get it that sometimes, because of time constraints, or you don’t understand the fundamentals of the language and are not interested in it, or it was your last day at the company, or you don’t understand outcomes from a feature that is expected, whatever it may be, you did what you did. Still, now that is going to serve the people you don’t even know.
Now coming back to it, the first approach everyone should take is to build the monolithic system more modular and define the boundaries for each module in such a way that you know when something is off where you should be looking. Second, understand the process of every module and compare their performance after doing some fixes and removing those nested loops or recursive calls and throwing some caching in it, try reducing multiple database calls by doing many more optimized queries, making high compute operations asynchronous, split the operations, and etc. After that, if you still have problems, go ahead and pick one module that is having performance issues and fewer dependencies and start building the microservice by just replicating it and using a message broker like Kafka to communicate with the dependencies of the old system for that service to produce and consume the message triggered by some event asynchronously and observe the new microservice if it is working as expected. By doing so, you are having the same service working in both systems; this gives you insight into how performant the microservice will be, and not break the existing system by bringing a foreign architecture with no knowledge of where and when it may start showing some grey areas.
Building software is always about numbers, assumptions, precedence, resources, and rewrites. A microservice for a startup company where the number of people working on the software is fewer than 50 is not a very good choice. If you are doing this, then it is a clear sign that you don’t understand what the goal of the software is and how to use the resources you have. You are either exploiting the resources you have just because you can or you read an article about how monoliths can bring you unforeseen troubles. In any case, you are always responsible for every duct tape to every exploit.
In my conclusion, I can only state, build everything as simply as possible and this comes with failing experiences and not by writing more code the same way every time. State the boundaries very carefully and adhere to those to keep the parts and pieces decoupled as much as possible while doing the job they are responsible for. Read and watch people building software still alive for more than 10 years, because they may share some opinions that can be hard to digest but they have experienced the worst you could ever imagine (a world without AWS or Cloudflare). I like the benefits of monoliths and microservices and I can use both if I have to that gives me more control over making future decisions which is always the case in building software where people lose control and may get sidetracked.
So in the end, it is all up to the understanding, the ego, and the satisfaction, since we are human in the end and we have feelings. Every wrong decision is a step towards upskilling.
Good luck! | sourabpramanik |

Traditionally, this involves a third party, but in this case, the third party is an honest one facilitated by the smart contract. This contract involves three parties: the Depositor, the Arbiter, and the Beneficiary.
**Depositor:** The payer in the escrow agreement.
**Beneficiary:** The recipient of the funds from the escrow after the Arbiter confirms the transaction, typically for providing some service to the Depositor.
**Arbiter:** The trusted middleman responsible for approving the transaction. The Arbiter ensures the goods or services are received before releasing the funds.
**_From the lessons at Alchemy University, I learned to create an escrow smart contract with the following key components:_**
1. **State Variables:** Understanding and declaring variables that store the contract's state.
2. **Constructor:** Initializing the contract with specific parameters.
3. **Payable Constructor:** Allowing the constructor to handle Ether transactions.
4. **Functions:** Implementing the contract's logic through functions.
5. **Function Security:** Restricting function calls to specific addresses for security purposes.
6. **Events:** Emitting events to log significant actions in the contract.
**Here's a sample implementation of an escrow smart contract in Solidity:**
```
// SPDX-License-Identifier: MIT
pragma solidity 0.8.20;
contract Escrow {
address public depositor;
address public beneficiary;
address public arbiter;
constructor(address _arbiter, address _beneficiary)payable{
depositor = msg.sender;
arbiter = _arbiter;
beneficiary = _beneficiary;
}
function approve()external {
//check if the caller of the function is the arbiter.
require(msg.sender == arbiter, "Only arbiter can approve");
uint balance = address(this).balance;
payable(beneficiary).transfer(balance);
emit Approved(balance);
}
event Approved(uint);
}
```
This contract ensures that only the Arbiter can approve the transfer of funds to the Beneficiary, adding a layer of security and trust to the transaction process.
**_Please, questions and contributions are welcome_**

Social media is a mess for most people, but it is a hidden Gem for business owners. In our decade-long journey as a social media marketing service provider, we saw some small business owners frustrated for not understanding relevant content, not understanding ROI, not having engagement ideas, and not having a strong business focus.
Success requires a growth mindset and the ability to take risks. They are unsuccessful because they need some clarification about social media marketing. Such as:
1) I need a huge social media presence for a successful business.
You don't need it because everyone is not your customer. If your content is for everyone, then your content is for no one. Do deep research on your target audience& make content for them.
2) The more followers I have, the better.
When you post content (Optimal Posting best practices), social media shows it to a small group of people, and it observes how people react to it.
Based on this result, social media algorithms choose how to distribute this piece of content on the internet.

1,873,088 | Building Your First Browser Game with Three.js and React: Part 4 - Adding Game Mechanics | Welcome to the final post of our series on creating a browser game with Three.js and React. In this... | 27,308 | 2024-06-01T15:28:58 | https://rherault.dev/articles/create-3d-game-part-4 | webdev, react, threejs, tutorial | Welcome to the final post of our series on **creating a browser game with Three.js and React**. In this piece, we'll introduce **game mechanics** to our mini-basketball game. We'll specifically establish a **scoring system** using **Zustand** for state management and configure **colliders** in our Table component to detect when the ball passes through the hoop.
## Step 1: Setting Up Zustand
First, we're going to use [Zustand](https://github.com/pmndrs/zustand) to manage our game score. Zustand is a lightweight, fast, and scalable **state management** solution for React.
While there are many state management options for React, I favor Zustand for its simplicity and it’s created by **Pmndrs**, the creators of R3F!
We need state management to **store** the score of the current game. This allows us to trigger increments in our table component and pass these values to our Interface. State management simplifies the process of **sharing values across all our components**.
To start, we need to install it:
```bash
npm install zustand
```
With Zustand installed, let's proceed to create the store. This is a file used for defining the values to be stored and shared across your components.
To do this, create a new file named `src/stores/useGame.js` and set up the store:
```jsx
import { create } from 'zustand'
export default create((set) => {
return {
/**
* Score
*/
score: 0,
increment: () => set((state) => ({ score: state.score + 1 })),
}
})
```
Our store is straightforward, containing just one variable: `score`, which keeps track of the number of balls we score. It also has a simple function `increment` that increases this score.
## Step 2: Displaying the Score
Next, we'll display the score on the **game interface** by creating a very simple HTML interface.
First, create a new file named `Interface.jsx` inside the `src/` directory:
```jsx
import useGame from "./stores/useGame"
const Interface = () => {
const points = useGame((state) => state.score)
return <div className="points">
<h1>{points} points</h1>
</div>
}
export default Interface
```
In this interface, we utilize our store to retrieve and display the actual game score within a `div` inside an `h1` tag.
Next, we need to import it into our app. Since this component is not 3D-related, let's add it to our `main.jsx` file outside of our `Canvas`:
```jsx
import React from 'react'
import ReactDOM from 'react-dom/client'
import { Canvas } from '@react-three/fiber'
import Experience from './Experience'
import './index.css'
import Interface from './Interface'
ReactDOM.createRoot(document.getElementById('root')).render(
<React.StrictMode>
<Interface />
<Canvas>
<Experience />
</Canvas>
</React.StrictMode>
)
```
You should see your interface in the top-left corner of the scene, as shown:
While it isn't bad, it’s very ugly. Let's add some CSS to enhance its appearance slightly. Open the existing `index.css` file and append the following at the end:
```css
.points {
position: fixed;
top: 0;
left: 0;
width: 100%;
z-index: 999;
display: flex;
justify-content: center;
align-items: center;
color: #fff;
font-size: 1.25rem;
}
```
Great! The text is now centered, enlarged, white, and a little less unattractive (you can still improve it yourself!):
## Step 3: Implementing Colliders
Now, we need to **detect** when the ball passes through the hoop using **colliders** in the `Table` component.
Colliders not only add physics to our object but also define areas where objects are **detected** when passing through.
Let's add our first collider to the hoop. Locate the `nodes.Ring.geometry` within the Table component:
```jsx
const Table = (props) => {
return (
<group {...props}>
{/* ... */}
<CuboidCollider
args={[0.35, 0, 0.35]}
position={[-1.686, 1.40, 0]}
sensor
>
<mesh
castShadow
receiveShadow
geometry={nodes.Ring.geometry}
material={materials.Red}
position={[0, 0.06, 0]}
/>
</CuboidCollider>
{/* ... */}
</group>
);
};
```
We've added a custom `CuboidCollider` to our Ring with a unique property `sensor`. A [**sensor**](https://github.com/pmndrs/react-three-rapier?tab=readme-ov-file#sensors) allows for specific functions like `onIntersectionEnter` or `onIntersectionExit`. These functions can detect when an object enters or exits this specific collider. If we define a **collider** with the sensor, this collider won't generate any contact points. Its only purpose is to detect other objects.
Remember to **adjust the position** of our Ring. This is because now it's the parent collider that defines the position of our mesh.
Now, if you look inside your ring, you should see the cuboid collider as illustrated below:
This component should detect when the ball enters it. To achieve this, we simply need to add a function at the beginning of our component and use it in our collider:
```jsx
import useGame from '../stores/useGame';
const Table = (props) => {
// ...
const increaseScore = useGame((state) => state.increment)
// ...
return (
<group {...props}>
{/* ... */}
<CuboidCollider
args={[0.35, 0, 0.35]}
position={[-1.686, 1.40, 0]}
sensor
onIntersectionExit={increaseScore}
>
<mesh
castShadow
receiveShadow
geometry={nodes.Ring.geometry}
material={materials.Red}
position={[0, 0.06, 0]}
/>
</CuboidCollider>
{/* ... */}
</group>
);
};
```
We've created a function called `increaseScore` that utilizes the `increment` function from our store. This function is used within the `onIntersectionExit` property of the CuboidCollider.
You can now play your game! Let's score some balls.
However, there is a problem.
You may have noticed that sometimes the score increases by two, or if the ball bounces too much and enters the hoop a second time, the score increases multiple times.
We need to verify this. We need to **determine if the ball is returning to our thruster**.
To do this, we already have all the necessary information! We just need another **collider**! 🎉
Let's add this collider and implement some **conditions for our goal**:
```jsx
import { useRef, useState } from 'react'
import useGame from '../stores/useGame';
const Table = (props) => {
// ...
const [isScored, setIsScored] = useState(false)
const increaseScore = useGame((state) => state.increment)
const goal = () => {
if(!isScored) {
setIsScored(true)
increaseScore()
}
}
// ...
return (
<group {...props}>
<RigidBody type='fixed' colliders='trimesh' restitution={0.6} friction={0}>
<mesh
castShadow
receiveShadow
geometry={nodes.Table.geometry}
material={materials.Wood}
position={[0, 0.068, 0]}
/>
{/* Add this collider inside the RigidBody of the Table mesh */}
<CuboidCollider
args={[0, 2, 1.5]}
position={[1.5, 1.5, 0]}
sensor
onIntersectionExit={() => {
setIsScored(false)
}}
/>
</RigidBody>
{/* ... */}
<CuboidCollider
args={[0.35, 0, 0.35]}
position={[-1.686, 1.40, 0]}
sensor
onIntersectionExit={goal}
>
<mesh
castShadow
receiveShadow
geometry={nodes.Ring.geometry}
material={materials.Red}
position={[0, 0.06, 0]}
/>
</CuboidCollider>
{/* ... */}
</group>
);
};
```
Here's what we've done: we've added a **state** to our Table component using the `useState` hook. This state helps us determine whether we've already scored or not. We've also created a `goal` function to increment the score and set this state to `true`. This prevents indefinite score incrementing when the ball has already been scored but hasn't returned to the thruster yet.
To detect if the ball has returned to the thruster and is ready for another shot, we've placed a new `CuboidCollider` on our Table and reset the state to `false`.
You should now see the new collider positioned right in front of the thruster.
Now, when we launch the ball and it passes through our hoop, the goal function checks if we've already scored. If we haven't, it increments our score and sets the state to `true`. When we pass through our new Collider in front of our thruster, this variable switches to `false`, and we're ready to score again.
This improvement **prevents us from scoring multiple points with one shot** like we could before.
Finally, we can go to our `Experience.jsx` file and delete the `debug` property from the Physics component.
## Conclusion
Congratulations! You've successfully incorporated game mechanics into your browser game using Three.js and React. You now have **a fully functioning mini-basketball game** equipped with a scoring system. This marks the end of our series on building your first browser game. Continue to experiment and add new features to further enhance your game.
In the future, I'll include some **bonus articles** to further **improve the game**, such as **adding confetti** when scoring, and so on.
There's always room for improvement in this game! For instance, Aezakmi from the **Three.js Journey Discord** suggested adding some "randomness" to the force of the thruster. I've included his message below in case it sparks some ideas:
> So basically you have "puncher" state between 0 and 1, where 0 is full down, and 1 is full up.
To calculate the force you gotta do the (1.0 - puncherState)*forceValue . For example if the ball collide with puncher being halfway up, you gonna apply (1.0 - 0.5) * forceValue and if pucher is full up the force gonna be zero (1.0 - 1.0) * forceValue.
>
>
> Now we need to calculate the direction for the force to apply.
> Thats gonna be even easier. Just do new Vector3().subVectors(ball.position, puncher.position).normalize().
This topic might be a bit advanced, but I believe everyone will be able to grasp it after this series!

- React Compiler
- Hydration error improvements
- Caching updates
**React Compiler:**
In order to optimize applications, React Compiler automatically memoizes your code. You may be familiar today with memoization through APIs such as useMemo, useCallback, and React.memo. With these APIs you can tell React that certain parts of your application don’t need to recompute if their inputs haven’t changed, reducing work on updates. While powerful, it’s easy to forget to apply memoization or apply them incorrectly. This can lead to inefficient updates as React has to check parts of your UI that don’t have any meaningful changes.
The compiler uses its knowledge of JavaScript and React’s rules to automatically memoize values or groups of values within your components and hooks. If it detects breakages of the rules, it will automatically skip over just those components or hooks, and continue safely compiling other code.
[Click for more details](https://react.dev/learn/react-compiler)
**Hydration error improvements:**
Next.js 14.1 made improvements to error messages and hydration errors. Next.js 15 continues to build on those by adding an improved hydration error view. Hydration errors now display the source code of the error with suggestions on how to address the issue.
For example, this was a previous hydration error message in Next.js 14.1:
Next.js 15 RC has improved this to:
**Caching updates:**
With Next.js 15, we’re changing the caching default for fetch requests, GET Route Handlers, and Client Router Cache from cached by default to uncached by default. If you want to retain the previous behavior, you can continue to opt-into caching.
We're continuing to improve caching in Next.js in the coming months and we'll share more details in the Next.js 15 GA announcement.
`fetch('https://...', { cache: 'force-cache' | 'no-store' });`
- no-store - fetch a resource from a remote server on every request and do not update the cache
- force-cache - fetch a resource from the cache (if it exists) or a remote server and update the cache
[Click for more details](https://nextjs.org/blog/next-15-rc#caching-updates)
The best part is the update in hydration error! | hussain101 | |

Spring, bir sınıfın bağımlılıklarını otomatik olarak enjekte etmek için `@Autowired` anotasyonunu kullanır. Ancak, aynı türden birden fazla bean (nesne) varsa, Spring hangi bean'in enjekte edileceğini bilemez ve bu durumda `@Qualifier` kullanılır. `@Qualifier`, hangi bean'in enjekte edileceğini belirlemek için kullanılır.
### @Qualifier Kullanımı
1. **Tanımlama**: İlk olarak, birden fazla bean oluşturulmalıdır. Her biri farklı bir isimle tanımlanır.
```java
@Configuration
public class AppConfig {
@Bean
public Vehicle car() {
return new Car();
}
@Bean
public Vehicle bike() {
return new Bike();
}
}
```
2. **Enjeksiyon**: Daha sonra, `@Autowired` ile birlikte `@Qualifier` kullanarak belirli bir bean'i enjekte edebilirsiniz.
```java
public class VehicleService {
private final Vehicle vehicle;
@Autowired
public VehicleService(@Qualifier("car") Vehicle vehicle) {
this.vehicle = vehicle;
}
public void service() {
vehicle.drive();
}
}
```
Bu örnekte, `VehicleService` sınıfı içinde `car` bean'i enjekte edilir. Eğer `@Qualifier` kullanılmazsa ve birden fazla `Vehicle` türünde bean varsa, Spring bir çakışma hatası verir.
### @Qualifier'ın Avantajları
- **Netlik**: Hangi bean'in enjekte edileceği açıkça belirtilir.
- **Çakışma Önleme**: Aynı türden birden fazla bean olduğunda, çakışmaları önler.
- **Kontrol**: Geliştiriciye daha fazla kontrol sağlar ve hangi bean'in kullanıldığını belirtmek için esneklik sunar.
### Özet
`@Qualifier` anotasyonu, Spring'de bağımlılık enjeksiyonunu özelleştirmek ve belirli bean'leri seçmek için kullanılır. `@Autowired` anotasyonu ile birlikte kullanıldığında, aynı türden birden fazla bean olduğunda hangi bean'in enjekte edileceğini açıkça belirler. Bu, çakışmaları önler ve kodun daha okunabilir ve bakımı daha kolay olmasını sağlar. | mustafacam | |

### Advance Options for embed view implemented
The embedded view of CircuitVerse circuits can be used to display circuits in an iframe on other websites.
By clicking the Embed button on the bottom right, a dialog box can be opened, allowing the user to create a customised embed view for the circuit.
As you can see in the Advance option section user gets to decide which properties should be there in the embed view.
The Embed view Advance option was already implemented in the previous year GSoC i.e in GSoC’22 by this PR — Link, now was the time to implement the same in the Vue Simulator. The implementation was a bit different, as we could now use Vue’s reactive nature to make the task easier.
In the embed Component we will get the preference data from the params using the `useRoute` method.
```typescript
import { useRoute } from 'vue-router'
const route = useRoute()
const hasDisplayTitle = ref(route.query.display_title ? route.query.display_title === 'true' : false);
const hasClockTime = ref(route.query.clock_time ? route.query.clock_time === 'true' : true);
const hasFullscreen = ref(route.query.fullscreen ? route.query.fullscreen === 'true' : true);
const hasZoomInOut = ref(route.query.zoom_in_out ? route.query.zoom_in_out === 'true' : true);
```
Then we can use data to conditionally render components.
```html
<div v-if="hasZoomInOut.value" id="zoom-in-out-embed" class="zoom- wrapper">
```
You can checkout the Pull Request here — https://github.com/CircuitVerse/cv-frontend-vue/pull/312
### Fix for Timing Diagram increase decrease buttons
Previously, the increase and decrease buttons of the timing diagram were not working.
Using Vue's reactives fixed the problem, link to the PR - https://github.com/CircuitVerse/cv-frontend-vue/pull/313
### A PR for all bug fixes and updates from the main repo
Since decoupling of the new vue simulator some updates and bug fixes were made in the main simulator which needs to be updated in the vue simulator.
It is a single PR for all the updates that can be directly applied to the Vue simulator without any changes, with different commit for each issue - https://github.com/CircuitVerse/cv-frontend-vue/pull/314
### Conclusion
I have learned a lot more about the codebase and good practices. It was a good start, and I am now more excited to move on to the next tasks. Thanks to all my mentors who helped me plan the timeline for tasks; it helped me get a good start.

Now I am going to make a random scratch game in 3 different time periods and I don't know why I am doing this but I went on
## 45 sec scratch game
A 45 sec is pretty difficult to do because we should make sprites, backdrops and function them in just 45sec. I thought I could make a game in 45sec but I failed in doing it properly. This was the worst game I have ever coded or done in my life because it included a ball which moves with our mouse pointer and when It touches the edge we get a point and it's sprites were very bad and it does not have a backdrop just a white screen with a blue ball.
## 1min scratch game
A 1min scratch game is just 15sec more than the 45sec scratch game so the results would almost be the same the same but it was more better than I expected how it would be. I made a scratch cat clicker game which has white backdrop a scratch cat in the middle a and when we clicked it the score would increase.
## 10min scratch game '
Ten minutes is very high time and I thought it was very low so I decided a different type of car game where there will be speed and other different entities that are in a car but that is not possible so I simply made a normal scratch car game and I did it before 10min and a lot of time has been wasted and the game also is very bad.

1,873,078 | Why You Shouldn’t Pass React’s setState as a Prop: A Deep Dive | In a React application, passing the setState function from a parent component to its children... | 0 | 2024-06-01T15:17:41 | https://dev.to/christopherthai/why-you-shouldnt-pass-reacts-setstate-as-a-prop-a-deep-dive-4bc8 | javascript, react, webdev, programming | In a React application, passing the setState function from a parent component to its children component as a prop is a common method to manage the state across different parts of the application. However, this seemingly convenient method can introduce a host of issues that can compromise the maintainability, performance, and structure of the React application. This blog post will dive into these issues, explaining why we shouldn’t pass setState as a prop in React function components and provide you with better practices and state management approaches.
##Functional Components and Hooks##
Before we delve into the core issues, it’s crucial to grasp the benefits of React function components enhanced by Hooks. These advancements provide superior, simpler, and more efficient ways to manage the state within the React application. Hooks enable the use of state and other React features within function components, promoting component reusability and functional patterns.
##Problems with Passing setState as a Prop##
###Breaks the Principle of Encapsulation###
Encapsulation is a crucial principle in React and component-based architecture, emphasizing that components should manage their own logic and state independently. Encapsulation ensures that components are loosely connected and can operate independently, improving testability and reusability.
View this example where the parent component passes its setState function to the child components:
```
// Define a functional component called ParentComponent
const ParentComponent = () => {
// Declare a state variable called count and a function to update it called setCount, initialized to 0
const [count, setCount] = useState(0);
// Render the JSX elements
return (
<div>
{/* Render the ChildComponent and pass the setCount function as a prop called setCount */}
<ChildComponent setCount={setCount} />
{/* Display the value of count */}
<p>Count: {count}</p>
</div>
);
};
// Define a functional component called ChildComponent
const ChildComponent = ({ setCount }) => {
// Render a button that triggers the setCount function when clicked and increments the count by 1
return <button onClick={() => setCount(count => count + 1)}>Increment</button>;
};
```
In this code example, the ChildComponent directly changes or manipulates the state of ParentComponent, which makes it tightly connected with the parent and less reusable in other contexts.
One metaphor about encapsulation and how passing setState as a prop breaks the principle of encapsulation is thinking encapsulation is like having your own garden where you control what grows and how it’s maintained. Passing setState as a prop is like letting your neighbor decide when to water your plants. It disrupts the independence of your garden, blending the boundaries between your space and theirs.
###Increase Complexity###
Passing the setState down as a prop from the parent component to the child component raises the complexity of the component hierarchy. It can change the source of the state changes and make it harder to track how and where the state is getting updated or changed. All of these can make it more challenging to diagnose and fix issues, especially in large applications with deep and many component trees.
These can also make it more complex when trying to refactor the codes. Just changing the state structure in the parent components may also require changing the child components that get and receive the setState function, which can lead to a codebase that will be hard and resistant to change.
One metaphor about this is passing a setState as a prop is like adding extra switches and levers to every room in a house that controls the same light. It complicates knowing which switch was used to turn on the light, adding unnecessary complexity to a simple action.
###Performance Concerns###
If the setState is misused, it can lead to performance issues and unnecessary re-renders. Suppose a child’s components randomly update the parent’s state. In that case, it can lead to a re-render of the parent and its entire subtree, regardless of whether the update logically and reasonably requires such a widespread re-render. React works hard to update the apps smoothly, but it can slow things down if state changes happen more often than needed. This is especially true for big and complex applications with large numbers of components.
One metaphor about this is passing a setState as a prop, which is like having too many cooks in the kitchen. Just as too many cooks can slow down meal preparation by getting in each other’s way, too many components trying to manage the same state can slow down the app by triggering unnecessary updates and re-renders.
##Better State Management Approaches##
Given the drawback of passing setState as a prop, let’s explore an alternative state management pattern that adheres to React’s best practices.
###Lifting State Up###
The “lifting state up” pattern involves moving the state to the nearest common ancestor of the component that needs it. This helps centralize state management and avoid the need to move or pass the state around.
```
// Define a functional component called ParentComponent
const ParentComponent = () => {
// Declare a state variable called count and a function to update it called setCount, initialized to 0
const [count, setCount] = useState(0);
// Define a function called incrementCount that increments the count by 1
const incrementCount = () => setCount(prevCount => prevCount + 1);
// Render the JSX elements
return (
<div>
{/* Render the ChildComponent and pass the incrementCount function as a prop called onIncrement */}
<ChildComponent onIncrement={incrementCount} />
{/* Display the value of count */}
<p>Count: {count}</p>
</div>
);
};
// Define a functional component called ChildComponent
const ChildComponent = ({ onIncrement }) => {
// Render a button that triggers the onIncrement function when clicked
return <button onClick={onIncrement}>Increment</button>;
};
```
The above pattern reuses the child component, ensuring a clear and orderly flow of state, which aids in maintaining structure and clarity.
One metaphor about lifting state up is like moving a water tank to the roof of an apartment building. This way, gravity ensures water flows down and distributes to all apartments evenly.
###Using Context API###
For more global state management needs, the Context API provides an excellent and efficient solution to share states across the entire component tree with prop drilling.
```
// Create a context
const CountContext = React.createContext();
function ParentComponent() {
const [count, setCount] = useState(0); // State
const incrementCount = () => setCount(count + 1); // Function to increment the count
return (
// Wrap the child component with the context provider
<CountContext.Provider value={{ count, incrementCount }}> // Provide the value to the context
<ChildComponent /> // Child component
</CountContext.Provider> // Close the context
);
}
function ChildComponent() {
const { incrementCount } = useContext(CountContext); // Access the value from the context
return <button onClick={incrementCount}>Increment</button>; // Render a button that triggers the increment function
}
```
The Context API facilitates an improved method for managing and accessing state throughout the components tree. This approach allows for streamlined state sharing across the application, which improves state management efficiency and component communication.
One metaphor about Context API is that it is like a public bulletin board in a building: once a message is posted, anyone in the building can see it without needing to pass notes from person to person.
###Custom Hooks###
Custom hooks in React are reusable functions that let you share logic and stateful behavior between components. They encapsulate both the state and related logic, making them an efficient tool for distributing functionality across components.
```
// Custom hook to manage the count state
const useCounter = (initialValue = 0) => {
const [count, setCount] = useState(initialValue); // State variable to hold the count value
const incrementCount = () => setCount(count + 1); // Function to increment the count
return { count, incrementCount }; // Return the count value and increment function
};
// Parent component using the custom counter hook
const ParentComponents = () => {
const { count, incrementCount } = useCounter(); // Destructure the count value and increment function from the custom hook
return (
<div>
<ChildComponent onIncrement={incrementCount} /> // Render the child component and pass the increment function as a prop
<p>Count: {count}</p> // Display the count value
</div>
);
};
// Child component that receives the increment function as a prop
const ChildComponents = ({ onIncrement }) => {
return <button onClick={onIncrement}>Increment</button>; // Render a button that triggers the onIncrement function when clicked
};
```
Custom Hooks enabled modular sharing of logic across components, enhancing and improving the readability, organization, and conciseness of the application. This approval streamlines development, making maintaining an efficient and clean codebase easier.
One metaphor about custom hooks is they are like toolkits that you can carry around, allowing you to reuse tools (logic and state management) in different projects (components) effortlessly.
##Conclusion##
Passing ‘setState’ as a prop in React can result in some bad outcomes. It tends to violate the principle of encapsulation, where the components are supposed to manage their own logic and state independently. This can add unnecessary complexity to the application’s structure and degrade the performance through unnecessary and inefficient rendering processes. Luckily, React offers more effective state management techniques that prevent these issues. Those techniques include “lift state up” to a common parent component, utilizing the Context API for widespread state access, and designing custom hooks to shared state logic from a parent component to the child component. These techniques and strategies can surgically improve React applications’ efficiency, scalability, and maintainability. | christopherthai |

1,873,075 | How to Use Helper Functions? | In Javascript programming, the idea of helper functions is a fundamental principle that helps to... | 0 | 2024-06-01T15:10:09 | https://dev.to/christopherthai/how-to-use-helper-functions-4lpi | javascript, webdev, beginners, programming | In Javascript programming, the idea of helper functions is a fundamental principle that helps to improve code maintainability, readability, and efficiency. These functions are usually designed to perform specific tasks regularly required across different parts of an application. By making these tasks into separate, well-defined functions, software developers can avoid writing the same code multiple times, simplifying complex operations, and making the codebase look concise, clean, and easy to read and understand by other developers. This blog will cover more about the helper function, such as its characteristics, importance, benefits, some examples, and ways to organize more effectively and efficiently within more extensive applications.
##What are Helper Functions?##
Helper functions are small, reusable functions that carry out specific calculations or tasks. These functions encourage the DRY (Don’t Repeat Yourself) principle so that code is not unnecessarily duplicated across the application. This technique will help save effort and time, minimize the risk of bugs, and make it easy to change one piece of the code logic in one place.
##What are the Characteristics of Helper Functions?##
1. **Reusability** Helper functions are designed to be reusable so they can be reused in different parts of an application and other projects.
2. **Having No Side Effects:** Helper functions should not cause any side effects in the application or project. Their output should only depend on its input, which makes it easier to debug and predictable.
3. **Having a Single Responsibility:** Each helper function should only be responsible for one piece of functionality or operation. This makes functions more reusable and more accessible to debug.
##What are the Benefits of Helper Function?##
1. **Improve Readability:** Well-defined name helper functions can clarify the intentions behind a code block and make parts of the code more understandable and readable.
2. **Decrease Code Repetition:** The helper function can consolidate similar tasks and decrease code repetition. This can make the codebase more feasible and decrease the risk of bugs and errors.
3. **Make Testing Easier:** Since helper functions are designed to execute one task, they are much easier to test.
4. **Easy to Maintain:** Dedicating one task or functionality to a helper function simplifies changing, updating, and maintaining an application. If a specific functionality is needed, a change must be made only once in the code.
##Some Examples of Helper Functions##
Let’s see some examples where helper functions can be helpful:
###Calculation: Addition, Subtract, Multiply, & Divide###
```
const addition = (a, b) => {
return a + b
}
```
```
const subtract = (a, b) => {
return a - b
}
```
```
const multiply = (a, b) => {
return a * b
}
```
```
const divide = (a, b) => {
return a / b
}
```
All four functions above pass two numbers as arguments and return the result based on the operation: addition, subtraction, multiplication, or division. These functions can be useful and reused in making calculations like the total price of each item in the shopping cart.
###Capitalizing the First letter of a String###
```
const capitalizeFirstLetter = (string) => {
return string.charAt(0).toUpperCase() + string.slice(1).toLowerCase();
}
```
The function will take in an input a string and separate it by uppercasing the first letter, lowering the rest of the letters, and combining them. This function is useful for ensuring that user input is always and consistently formatted.
###Capitalizing the First Letters of the Words in a Sentence###
```
const upperCaseFirstLetterInSentence = (string) => {
return string.toLowerCase().split(' ').map(word => word.charAt(0).toUpperCase() + word.slice(1)).join(' ');
}
```
The function will take input as a string, a sentence in this case, and return a new string in which the first letter of the words in the sentence is uppercase. This function would be very useful for formatting text for display purposes.
###Checking if a Number is Even###
```
const isEven = (number) => {
return number % 2 === 0;
}
```
The function checks if a number is even or not. It takes a number, divides it by two, and checks if the remainder is equal to zero. The function is helpful because it’s reusable, so you don’t have to write the same code many times when checking if a number is even or not.
###Converting Fahrenheit to Celsius###
```
const fahrenheitToCelsius = (fahrenheit) => {
return (fahrenheit - 32) * 5 / 9;
}
```
The function is simply a temperature conversion, converting Fahrenheit to Celsius. It is useful when making calculations in weather and science applications.
###How to Organize Helper Functions?###
There will be a time when you will use many help functions on big applications. So, organizing them will be essential to maintain a clean and concise codebase. A helpful tip is to group the helper functions into modules based on their functionality, such as numberUtils.js, stringUtils.js, or dateUtils.js, and import these modules when you need to use them or use their functionality. Another helpful tip is creating documentation explaining what each helper function does, the parameters, and return values. The last tip is to develop a suite of unit tests to ensure the helper functions are working as intended.
##Conclusion##
In conclusion, the helper function in Javascript is a powerful tool for developers who aim to promote and encourage code readability, reuse, and maintainability. Changing common tasks into reusable functions can make your code more manageable and straightforward to test, maintain, and read.
The takeaway from this blog is your understanding of the significance of helper functions. Thanks for reading the blog! | christopherthai |

Como alguém com uma vasta experiência de vida e uma carreira multifacetada, tanto na área de tecnologia quanto em gestão de projetos, sempre fui guiado por uma intuição prática e uma capacidade de leitura de ambientes que transcende a teoria formal.
Na minha trajetória, desde os primeiros passos como programador Cobol até a minha atuação atual na área de Gestão de Projetos e/ou Developer Relations, sempre utilizei abordagens que hoje sei identificar como SWOT. No entanto, naquela época, eu simplesmente seguia o "cheiro", confiando no meu feeling para tomar decisões estratégicas e operacionais.
Por exemplo, ao fundar e gerenciar empresas como TaNaObra, BrBoalt e Biosbug Informática, minha análise natural dos cenários e a capacidade de identificar pontos fortes e fracos, bem como as oportunidades de mercado e as possíveis ameaças, foram cruciais para o sucesso. Eu não chamava isso de SWOT, mas sim de bom senso e experiência de vida. Era como se eu tivesse uma bússola interna que me guiava nas decisões.
Hoje, com um entendimento mais formal e técnico, sei que minhas práticas intuitivas sempre seguiram os princípios da análise SWOT. Utilizava minhas experiências e observações para maximizar pontos fortes, como a habilidade de liderar equipes e inovar, e minimizar fraquezas, como a falta de certos recursos. Da mesma forma, sempre estive atento às oportunidades no mercado e vigilante em relação às ameaças, seja de concorrência, mudanças tecnológicas ou econômicas.
Na minha atual função de gestor de projetos, sou capaz de não apenas aplicar esses conceitos, mas também de explicá-los e documentá-los. Isso é fundamental para o desenvolvimento de roadmaps estratégicos e para a apresentação de planos detalhados às partes interessadas. Meu background em Developer Relations e em desenvolvimento web complementa essa capacidade, permitindo que eu me conecte com equipes técnicas e comunique claramente os objetivos e estratégias.
Portanto, apesar de minha abordagem inicial ter sido baseada na intuição e na experiência, hoje reconheço e valorizo o poder das ferramentas formais de gestão. A análise SWOT é uma delas, uma estrutura que agora posso nomear e utilizar conscientemente, mas que sempre esteve presente na minha prática diária de forma natural e instintiva.
Em resumo, a experiência de vida e a prática constante em diversos setores me ensinaram a navegar e a gerir com eficácia, mesmo antes de conhecer os nomes das ferramentas que utilizava. Agora, com um entendimento teórico e prático, estou preparado para integrar essas ferramentas formalmente nos processos de gestão, tornando minhas habilidades e intuições mais acessíveis e replicáveis para minhas equipes e projetos. | biosbug |

It’s almost impossible to guarantee 100% data protection but there are some key strategies that can ensure data protection to a great degree: Below I have tried touching on a few strategies.
1. Data Encryption: Encrypt sensitive data both at rest and in transit to prevent unauthorized access.
2. Access Controls: Implement strict access controls, ensuring only authorized personnel have access to sensitive data. Use role-based access controls (RBAC) and the principle of least privilege.
3. Regular Backups: Regularly back up data and store copies in secure, off-site locations. Test backups periodically to ensure they can be restored successfully.
4. Employee Training: This is one of the most key strategy and I feel Organisations don’t really pay enough attention to this. Conducting regular cybersecurity training for employees to recognize phishing attempts, social engineering, and other security threats. This cannot be overemphasised.
5. Network Security: Use firewalls, intrusion detection/prevention systems (IDS/IPS), and secure network architecture to protect against external threats.
6. Endpoint Protection: Deploy antivirus software, endpoint detection and response (EDR) solutions, and ensure devices are patched and updated regularly.
7. Data Loss Prevention (DLP): Implement DLP solutions to monitor and control the transfer of sensitive data outside the corporate network.
8. Incident Response Plan: Develop and maintain an incident response plan to quickly and effectively address data breaches or security incidents.
9. Compliance and Audits: Regularly audit and review security practices to ensure compliance with industry regulations and standards (e.g., GDPR, HIPAA, PCI DSS).
10. Cloud Security: If using cloud services, ensure cloud providers offer robust security measures and configure cloud settings securely.
11. Multi-Factor Authentication (MFA): Use MFA to add an extra layer of security for accessing corporate systems and data.
By implementing these strategies, organizations can significantly reduce the risk of data breaches and protect their valuable corporate data. | stevetechie | |

1,855,066 | React 19 Beta Release: A Quick Guide | React 19 Beta has been announced, it introduces several new concepts that simplify state management,... | 0 | 2024-06-01T14:24:32 | https://webdeveloper.beehiiv.com/p/react-19-beta-release-quick-guide | react, webdev, javascript, frontend | React 19 Beta has been announced, it introduces several new concepts that simplify state management, error handling, and asynchronous operations in React applications. In this article, I’ll quickly summarize these features so you can quickly grasp the main points.
# Simplifying Asynchronous Operations with Actions
One of the standout features in React 19 is the introduction of “Actions”. Actions are a new way to handle data mutations and state updates following asynchronous operations. Previously, developers had to manage pending states, errors, and optimistic updates manually, which could get cumbersome. React 19 aims to simplify this process significantly.
#### Example: Updating a User’s Name
Consider a common use case where a user submits a form to update their name. In earlier versions of React, you might handle the asynchronous API request like this:
```jsx
function UpdateName({}) {
const [name, setName] = useState("");
const [error, setError] = useState(null);
const [isPending, setIsPending] = useState(false);
const handleSubmit = async () => {
setIsPending(true);
const error = await updateName(name);
setIsPending(false);
if (error) {
setError(error);
return;
}
redirect("/path");
};
return (
<div>
<input value={name} onChange={(event) => setName(event.target.value)} />
<button onClick={handleSubmit} disabled={isPending}>
Update
</button>
{error && <p>{error}</p>}
</div>
);
}
```
With React 19, you can utilize the `useTransition` hook to handle the pending state more succinctly:
```jsx
function UpdateName({}) {
const [name, setName] = useState("");
const [error, setError] = useState(null);
const [isPending, startTransition] = useTransition();
const handleSubmit = async () => {
startTransition(async () => {
const error = await updateName(name);
if (error) {
setError(error);
return;
}
redirect("/path");
});
};
return (
<div>
<input value={name} onChange={(event) => setName(event.target.value)} />
<button onClick={handleSubmit} disabled={isPending}>
Update
</button>
{error && <p>{error}</p>}
</div>
);
}
```
This new approach automatically manages the pending state and error handling, making the code cleaner and more manageable.
### Enhancements in Form Handling
React 19 introduces several improvements in how forms can be managed, particularly through the integration of Actions into form elements. This new feature simplifies form submission processes and error handling.
#### Simplified Form Submission
Using Actions, forms can now automatically handle data submissions without the need for cumbersome error and state management. Here’s how you might use it:
```jsx
function ChangeName({ name, setName }) {
const [error, submitAction, isPending] = useActionState(
async (previousState, formData) => {
const error = await updateName(formData.get("name"));
if (error) {
return error;
}
redirect("/path");
}
);
return (
<form action={submitAction}>
<input type="text" name="name" />
<button type="submit" disabled={isPending}>Update</button>
{error && <p>{error}</p>}
</form>
);
}
```
This code snippet shows a form that utilizes the `useActionState` hook to manage the submission process. This hook encapsulates the logic for handling pending states, errors, and the actual data submission, reducing boilerplate and improving readability.
#### New Hook — `useFormStatus`
This hook allows components to access the form's status directly, treating it much like context. This is particularly useful for designing components that need to react to the form's state.
```jsx
import { useFormStatus } from 'react-dom';
function DesignButton() {
const { pending } = useFormStatus();
return <button type="submit" disabled={pending}>Submit</button>;
}
```
#### New Hook — `useOptimistic`
This hook allows developers to optimistically update the UI, providing instant feedback before the operation completes.
```jsx
function ChangeName({ currentName, onUpdateName }) {
const [optimisticName, setOptimisticName] = useOptimistic(currentName);
const submitAction = async formData => {
const newName = formData.get("name");
setOptimisticName(newName);
const updatedName = await updateName(newName);
onUpdateName(updatedName);
};
return (
<form action={submitAction}>
<p>Your name is: {optimisticName}</p>
<label>Change Name:</label>
<input type="text" name="name" disabled={currentName !== optimisticName} />
</form>
);
}
```
The useOptimistic hook will render optimisticName immediately while the updateName request is in progress. When the update completes or an error occurs, React automatically switches back to the currentName value.
### New API: `use`
`use` in React 19 designed to read resources during render. It supports suspending components until resources, like promises, resolve, enhancing the integration with React's Suspense feature.
```jsx
import { use } from 'react';
function Comments({ commentsPromise }) {
const comments = use(commentsPromise);
return comments.map(comment => <p key={comment.id}>{comment}</p>);
}
function Page({ commentsPromise }) {
return (
<Suspense fallback={<div>Loading...</div>}>
<Comments commentsPromise={commentsPromise} />
</Suspense>
);
}
```
### React Server Components
React Server Components allow rendering of components ahead of time, in a distinct environment separate from the client application. This feature enables execution at build time on a CI server or per request on a web server, improving performance and resource efficiency.
While Server Components are stable across major releases, the APIs for bundling or frameworks might change in minor releases. To ensure compatibility, it’s recommended to pin a specific React version or use the Canary release.
#### Server Actions
Server Actions in React 19 enable client components to invoke asynchronous server-executed functions. This interaction is streamlined through a `"use server"` directive, automating the reference passing between client and server.
### Enhancements in React 19
#### `ref` as a Prop
React 19 allows `ref` to be passed directly as a prop to function components, simplifying the component's code by eliminating the need for `forwardRef`.
```jsx
function MyInput({ placeholder, ref }) {
return <input placeholder={placeholder} ref={ref} />;
}
<MyInput ref={React.createRef()} />
```
#### Improved Hydration Error Handling
React 19 improves how hydration errors are reported, offering a clearer and more detailed message when mismatches occur.
#### `<Context>` as a Provider
The new React version allows `<Context>` to be used directly as a provider:
```jsx
const ThemeContext = createContext('');
function App({ children }) {
return <ThemeContext value="dark">{children}</ThemeContext>;
}
```
#### Cleanup Functions for `ref`
React 19 supports returning a cleanup function from `ref` callbacks, aiding in better resource management when components unmount.
```jsx
<input ref={ref => {
// Actions on ref creation
return () => {
// Cleanup actions
};
}} />
```
#### `useDeferredValue` with Initial Value
React 19 introduces an `initialValue` for `useDeferredValue`, allowing immediate use of a default value before any deferred updates.
```jsx
function Search({ deferredValue }) {
// On initial render the value is ''.
// Then a re-render is scheduled with the deferredValue.
const value = useDeferredValue(deferredValue, '');
return <Results query={value} />;
}
```
#### Advanced Document Metadata Management
React 19 supports rendering `<title>`, `<meta>`, and `<link>` tags within component renders, automatically managing their placement in the document's `<head>`.
```jsx
function BlogPost({ post }) {
return (
<article>
<h1>{post.title}</h1>
<title>{post.title}</title>
<meta name="author" content="Josh" />
<link rel="author" href="https://twitter.com/joshcstory/" />
<meta name="keywords" content={post.keywords} />
<p>Eee equals mc-squared...</p>
</article>
);
}
```
When React renders this component, it will see the `<title>` `<link>` and `<meta>` tags, and automatically hoist them to the `<head>` section of document.
#### Improved Handling of Stylesheets and Scripts
React 19 enhances how stylesheets and scripts are handled, ensuring proper loading order and avoiding duplication.
**Stylesheet Management Example:**
```jsx
function ComponentOne() {
return (
<Suspense fallback="loading...">
<link rel="stylesheet" href="foo" precedence="default" />
<link rel="stylesheet" href="bar" precedence="high" />
<article className="foo-class bar-class">{...}</article>
</Suspense>
);
}
function ComponentTwo() {
return (
<div>
<p>{...}</p>
<link rel="stylesheet" href="baz" precedence="default" /> <-- will be inserted between foo & bar
</div>
)
}
function App() {
return <>
<ComponentOne />
...
<ComponentOne /> // won't lead to a duplicate stylesheet link in the DOM
</>
}
```
**Async Scripts Example:**
```jsx
function MyComponent() {
return (
<div>
<script async={true} src="..." />
Hello World
</div>
)
}
function App() {
<html>
<body>
<MyComponent>
...
<MyComponent> // won't lead to duplicate script in the DOM
</body>
</html>
}
```
#### Support for Preloading Resources
React 19 introduces new APIs for loading and preloading resources, enhancing performance and user experience during initial loads and subsequent updates.
```jsx
import { prefetchDNS, preconnect, preload, preinit } from 'react-dom';
function MyComponent() {
// Eagerly loads and executes the script
preinit('https://.../path/to/some/script.js', { as: 'script' });
// Preloads the font
preload('https://.../path/to/font.woff', { as: 'font' });
// Preloads the stylesheet
preload('https://.../path/to/stylesheet.css', { as: 'style' });
// DNS prefetch for upcoming requests
prefetchDNS('https://...');
// Preconnects to the server for upcoming requests
preconnect('https://...');
}
// Resulting HTML from server-side rendering
<html>
<head>
<link rel="prefetch-dns" href="https://...">
<link rel="preconnect" href="https://...">
<link rel="preload" as="font" href="https://.../path/to/font.woff">
<link rel="preload" as="style" href="https://.../path/to/stylesheet.css">
<script async="" src="https://.../path/to/some/script.js"></script>
</head>
<body>
...
</body>
</html>
```
These APIs help optimize resource discovery and loading, improving performance by reducing load times during critical rendering paths.
#### Compatibility with Third-Party Scripts and Extensions
React 19 improves handling of third-party scripts and browser extensions during hydration. This enhancement prevents common mismatches and errors that occur when third-party scripts modify the DOM outside of React’s control.
#### Enhanced Hydration Compatibility
When hydrating, if React detects discrepancies due to third-party scripts, it now intelligently skips over unexpected tags rather than triggering re-render errors. This approach minimizes potential disruptions caused by external scripts and extensions, ensuring a smoother user experience.
#### Improved Error Reporting
React 19 streamlines error reporting by consolidating information and reducing the occurrence of duplicate error messages. This update provides clearer insights into component failures, especially within complex applications.
Additionally, React 19 introduces root options like `onCaughtError`, `onUncaughtError`, and `onRecoverableError`, offering more granular control over error handling across the application.
#### Full Support for Custom Elements
React 19 provides comprehensive support for custom elements, ensuring full compatibility with the [Custom Elements Everywhere](https://custom-elements-everywhere.com/?utm_source=webdeveloper.beehiiv.com&utm_medium=newsletter&utm_campaign=react-19-beta-release-a-quick-guide) standards. This support facilitates the integration of custom elements within React applications, improving interoperability and component reusability.

Bài viết này sẽ giúp bạn hiểu rõ hơn về cách chọn lựa và sử dụng sữa rửa mặt phù hợp nhất cho loại da này.
Đoạn Phát Triển:
Hiểu rõ về da hỗn hợp thiên khô: Để chăm sóc da hiệu quả, điều quan trọng là bạn phải hiểu rõ về tình trạng da của mình. Da hỗn hợp thiên khô có đặc điểm là vùng da T-zone (trán, mũi, và cằm) thường dầu và bóng, trong khi vùng da xung quanh khác thường khô và có thể bong tróc. Điều này đòi hỏi bạn cần một sản phẩm sữa rửa mặt có khả năng cân bằng dầu và độ ẩm trên da.
Tìm kiếm thành phần phù hợp: Khi lựa chọn sữa rửa mặt, hãy chú ý đến thành phần của sản phẩm. Da hỗn hợp thiên khô thường cần các thành phần như axit hyaluronic, glycerin, hoặc dầu hoa trà giúp cân bằng độ ẩm, cùng với các chất làm sạch nhẹ nhàng như axit salicylic hoặc enzym papain để loại bỏ dầu thừa mà không làm khô da.
Kiểm tra độ pH: Độ pH của sữa rửa mặt cũng là một yếu tố quan trọng. Da hỗn hợp thiên khô thường cần một sản phẩm có độ pH cân bằng, gần với pH tự nhiên của da (tầm 4.5 đến 5.5), giúp duy trì làn da mềm mại và không bị khô sau khi sử dụng.
Thực hiện thử nghiệm trước khi sử dụng: Trước khi áp dụng sữa rửa mặt lên toàn bộ khuôn mặt, hãy thử nghiệm sản phẩm trên một phần nhỏ da, chẳng hạn như sau tai, để đảm bảo không gây kích ứng hoặc mẩn đỏ.
Đoạn Kết: Với những bí quyết trên, việc lựa chọn sữa rửa mặt cho da hỗn hợp thiên khô sẽ dễ dàng hơn và hiệu quả hơn. Đừng quên rằng, việc duy trì làn da khoẻ mạnh đòi hỏi sự chăm sóc đúng đắn và liên tục. Hãy chọn sản phẩm phù hợp và duy trì một chế độ làm đẹp hàng ngày để có làn da mềm mại, sáng khỏe. | beauty_hadung | |

It's my second week of learning this new language, and I can attest that I'm intrigued and impressed so far.
It has intrusive capabilities and features compared to other languages that I have encountered in the past. Getting started with Golang as a self-taught wasn't easy at the start until I resorted to the right resources, which eventually enabled me to comprehend the new language.
Besides, the fact that I had knowledge of programming (before I took my Computer Science degree course) worked to my advantage since I could easily wrap my head around its concepts;
Fast forward: my 2-week stay in Golang has proved worthwhile since I have become so confident in my grasp of coding (at a basic level though) using the simplest and fastest language in the 21st century.
And here is everything I've covered so far:
1. Background history of Golang development
a. when it was developed;
b. why it was developed;
c. its features
2. Syntactic Structure
3. Variables
4. Constants
5. Operators
6. Arrays
7. Slices
8. Maps
9. Structs
10. Functions
11. Pointers
12. Loops
a. for
i. range
13. Conditional statements
a. if
b. if else
c. else if
i. break
ii. continue
Therefore, I decided to document everything I have covered, at the basic level, before I continue getting deeper and further. I believe this documentation has to play two vital roles:
1. Help me develop a better grasp of everything I have learned or covered so far. 2. Help in giving another aspiring (or beginner) Golang developer insights into the basics of the language.
Part II of this documentation shall be a continuation... from "Background History of Golang Development." | agoladev |

JavaScript provides a rich set of array methods to manipulate and work with arrays. Here is a comprehensive list of these methods along with sample usage:
Mutator Methods
These methods modify the array they are called on.
## push()
Adds one or more elements to the end of an array and returns the new length of the array.
sample:
```js
let arr = [1, 2, 3];
arr.push(4); // arr is now [1, 2, 3, 4]
```
## pop()
Removes the last element from an array and returns that element.
sample:
```js
let arr = [1, 2, 3];
let lastElement = arr.pop(); // arr is now [1, 2]; lastElement is 3
```
## shift()
Removes the first element from an array and returns that element.
sample:
```js
let arr = [1, 2, 3];
let firstElement = arr.shift(); // arr is now [2, 3]; firstElement is 1
```
## unshift()
Adds one or more elements to the beginning of an array and returns the new length of the array.
sample:
```js
let arr = [1, 2, 3];
arr.unshift(0); // arr is now [0, 1, 2, 3]
```
## splice()
Adds and/or removes elements from an array.
sample:
```js
let arr = [1, 2, 3, 4];
arr.splice(1, 2, 'a', 'b'); // arr is now [1, 'a', 'b', 4]
```
## sort()
Sorts the elements of an array in place and returns the sorted array.
sample:
```js
let arr = [3, 1, 4, 1, 5, 9];
arr.sort(); // arr is now [1, 1, 3, 4, 5, 9]
```
## reverse()
Reverses the order of the elements in an array in place.
sample:
```js
let arr = [1, 2, 3];
arr.reverse(); // arr is now [3, 2, 1]
```
## Accessor Methods
These methods do not modify the array and typically return a new array or a single value.
## concat()
Merges two or more arrays.
sample:
```js
let arr1 = [1, 2];
let arr2 = [3, 4];
let newArr = arr1.concat(arr2); // newArr is [1, 2, 3, 4]
```
## join()
Joins all elements of an array into a string.
sample:
```js
let arr = [1, 2, 3];
let str = arr.join('-'); // str is '1-2-3'
```
## slice()
Returns a shallow copy of a portion of an array into a new array.
sample:
```js
let arr = [1, 2, 3, 4, 5];
let slicedArr = arr.slice(1, 3); // slicedArr is [2, 3]
```
## indexOf()
Returns the first index at which a given element can be found in the array.
sample:
```js
let arr = [1, 2, 3];
let index = arr.indexOf(2); // index is 1
```
## lastIndexOf()
Returns the last index at which a given element can be found in the array.
sample:
```js
let arr = [1, 2, 3, 2];
let index = arr.lastIndexOf(2); // index is 3
```
## includes()
Determines whether an array includes a certain value.
sample:
```js
let arr = [1, 2, 3];
let hasTwo = arr.includes(2); // hasTwo is true
```
## toString()
Returns a string representing the array.
sample:
```js
let arr = [1, 2, 3];
let str = arr.toString(); // str is '1,2,3'
```
## toLocaleString()
Returns a localized string representing the array.
sample:
```js
let arr = [1, 2, 3];
let str = arr.toLocaleString(); // str might vary based on locale
```
## Iteration Methods
These methods iterate over the array, typically applying a function to each element.
## forEach()
Executes a provided function once for each array element.
sample:
```js
let arr = [1, 2, 3];
arr.forEach(element => console.log(element)); // logs 1, 2, 3
```
## map()
Creates a new array with the results of calling a provided function on every element.
sample:
```js
let arr = [1, 2, 3];
let doubled = arr.map(x => x * 2); // doubled is [2, 4, 6]
```
## filter()
Creates a new array with all elements that pass the test implemented by the provided function.
sample:
```js
let arr = [1, 2, 3, 4];
let evens = arr.filter(x => x % 2 === 0); // evens is [2, 4]
```
## reduce()
Applies a function against an accumulator and each element to reduce it to a single value.
sample:
```js
let arr = [1, 2, 3, 4];
let sum = arr.reduce((acc, curr) => acc + curr, 0); // sum is 10
```
## reduceRight()
Applies a function against an accumulator and each element (from right to left) to reduce it to a single value.
sample:
```js
let arr = [1, 2, 3, 4];
let sum = arr.reduceRight((acc, curr) => acc + curr, 0); // sum is 10
```
## some()
Tests whether at least one element passes the test implemented by the provided function.
sample:
```js
let arr = [1, 2, 3];
let hasEven = arr.some(x => x % 2 === 0); // hasEven is true
```
## every()
Tests whether all elements pass the test implemented by the provided function.
sample:
```js
let arr = [1, 2, 3];
let allPositive = arr.every(x => x > 0); // allPositive is true
```
## find()
Returns the first element that satisfies the provided testing function.
sample:
```js
let arr = [1, 2, 3];
let found = arr.find(x => x > 1); // found is 2
```
## findIndex()
Returns the index of the first element that satisfies the provided testing function.
sample:
```js
let arr = [1, 2, 3];
let index = arr.findIndex(x => x > 1); // index is 1
```
## flat()
Creates a new array with all sub-array elements concatenated into it recursively up to the specified depth.
sample:
```js
let arr = [1, [2, [3, 4]]];
let flatArr = arr.flat(2); // flatArr is [1, 2, 3, 4]
```
## flatMap()
First maps each element using a mapping function, then flattens the result into a new array.
sample:
```js
let arr = [1, 2, 3];
let flatMapped = arr.flatMap(x => [x, x * 2]); // flatMapped is [1, 2, 2, 4, 3, 6]
```
## entries()
Returns a new Array Iterator object that contains the key/value pairs for each index in the array.
sample:
```js
let arr = ['a', 'b', 'c'];
let iterator = arr.entries();
for (let [index, value] of iterator) {
console.log(index, value); // logs 0 'a', 1 'b', 2 'c'
}
```
## keys()
Returns a new Array Iterator that contains the keys for each index in the array.
sample:
```js
let arr = ['a', 'b', 'c'];
let iterator = arr.keys();
for (let key of iterator) {
console.log(key); // logs 0, 1, 2
}
```
## values()
Returns a new Array Iterator object that contains the values for each index in

1,873,050 | Converting an Integer to ASCII String in Go | Converting an integer to its ASCII string representation is a common task in programming. The process... | 0 | 2024-06-01T14:10:22 | https://dev.to/zone01kisumu/converting-an-integer-to-ascii-string-in-go-3269 | tutorial | Converting an integer to its ASCII string representation is a common task in programming. The process involves taking an integer value and transforming it into a string that represents the same number in human-readable form. In Go, this can be accomplished using a custom function. Below, we will go through a step-by-step explanation of how to implement such a function, followed by an example implementation.
**Step-by-Step Explanation**
1. Handle the Zero Case: If the integer is zero, return the string "0" directly.
2. Handle Negative Numbers: If the integer is negative, record the sign and convert the number to its positive equivalent for further processing.
3. Convert Digits to Characters: Extract each digit of the integer starting from the least significant digit (rightmost) and convert it to the corresponding ASCII character.
4. Construct the String: Build the resulting string by prepending each character.
5. Add the Sign: If the original integer was negative, prepend a minus sign to the result.
**Example Implementation**
Here is an example of a function, Itoa, that converts an integer to its ASCII string representation in Go:
```
package main
import (
"fmt"
)
func Itoa(n int) string {
if n == 0 {
return "0"
}
sign := ""
if n < 0 {
sign = "-"
n = -n
}
q := ""
for n > 0 {
digits := n % 10
q = string(rune('0'+digits)) + q
n /= 10
}
return sign + q
}
func main() {
fmt.Println(Itoa(0)) // Output: "0"
fmt.Println(Itoa(12345)) // Output: "12345"
fmt.Println(Itoa(-67890)) // Output: "-67890"
}
```
## Step 1: Handle the Zero Case
Handling the zero case is the first step in converting an integer to its ASCII string representation. It ensures that when the input integer is zero, the function immediately returns the string "0".
```
func Itoa(n int) string {
if n == 0 {
return "0"
}
// Other steps follow...
}
```
## Step 2: Handle Negative Numbers
Handling negative numbers involves identifying negative numbers and preparing them for conversion to their ASCII string representation. It ensures that negative numbers are correctly converted and that their negative sign is preserved in the resulting string.
```
func Itoa(n int) string {
// Step 1 code...
sign := ""
if n < 0 {
sign = "-"
n = -n
}
// Other steps follow...
}
```
## Step 3: Convert Digits to Characters
Converting digits to characters is a fundamental part of converting an integer to its ASCII string representation. It involves extracting each digit of the integer, starting from the least significant digit, and converting it to the corresponding ASCII character.
```
func Itoa(n int) string {
// Steps 1 and 2 code...
q := ""
for n > 0 {
digits := n % 10
q = string(rune('0'+digits)) + q
n /= 10
}
// Other steps follow...
}
```
## Step 4: Construct the Resulting String
Constructing the resulting string is the final step in converting an integer to its ASCII string representation. It involves combining the sign (if the number was negative) and the string of digits to form the final string representation of the integer.
```
func Itoa(n int) string {
// Steps 1, 2, and 3 code...
return sign + q
}
```
## Step 5: Add the Sign
Adding the sign is the final sub-step in constructing the resulting string for negative numbers. It ensures that the resulting string includes the negative sign at the beginning for negative numbers, making the string representation of the integer complete.
```
func Itoa(n int) string {
// Steps 1, 2, 3, and 4 code...
return sign + q
}
```
By following these steps, you can convert an integer to its ASCII string representation in Go. The above process allows you to represent integers as strings, making them suitable for display and manipulation in text-based environments.
You have been provided a comprehensive guide to converting integers to ASCII strings in Go, covering each step of the process in detail. Understanding these steps will help you convert integers to their string representations more effectively in your Go programs. | stellaacharoiro |

A recent... | 0 | 2024-06-01T13:49:44 | https://dev.to/goktugerol/apple-security-breach-protect-yourself-from-ransomware-and-data-theft-1dg9 | ransomware, applesecuritybreach, cyberthreats, cybersecurity | Have you ever considered buying a used Apple device or any used tech device? Think twice. A recent security breach highlights the risks associated with used devices and the importance of safeguarding your data.
**Exposed Serial Numbers and Data Theft**
A MacBook's exposed serial number can be exploited to steal your valuable data and lock you out of your device. This significant Apple security breach has raised concerns about the vulnerability of used devices.
Scammers are resourceful and can steal your data even if you haven't shared it with anyone. Keyloggers, software that records every keystroke on your computer, and unnoticed screen spying are just a couple of their tactics.
Here are two alarming examples of this security breach:
Case 1: https://discussions.apple.com/thread/255620960?sortBy=best
Case 2: https://forums.developer.apple.com/forums/thread/756247
This security breach raises serious questions about Apple's security measures. It shouldn't be this easy for malicious actors to exploit vulnerabilities and access users' data. Apple needs to address this issue promptly and patch the security hole.
**The Growing Threat of Ransomware**
In addition to data theft, the rise of ransomware attacks is another major concern. Ransomware encrypts or deletes your data, holding it hostage until you pay a ransom. These ransoms can range from small amounts to millions of dollars, with the highest publicly known ransom reaching a staggering $40 million.
Remember, there's no guarantee that your data will be released even after paying the ransom. It's crucial to protect your devices, be aware of the threats, and report any suspicious activity.
**Protect Yourself**
Here are some tips to protect yourself from data theft and ransomware attacks:
**Avoid buying used tech devices: **The risks associated with used devices are significant. Consider buying new or certified refurbished devices from reputable sellers.
**Be cautious about sharing information:** Avoid recording your screen, sharing screenshots (even with customer support), and disclosing sensitive information online.
**Use strong passwords and two-factor authentication:** Secure your accounts with strong, unique passwords and enable two-factor authentication whenever possible.
**Keep your software updated:** Regularly update your operating system and applications to patch security vulnerabilities.
**Back up your data:** Create regular backups of your important data and store them offline or in a secure cloud storage service.
**Be vigilant:** Stay informed about the latest cyber threats and be cautious of suspicious emails, links, and attachments.
By following these tips, you can significantly reduce your risk of falling victim to cyberattacks and protect your valuable data. | goktugerol |

1,869,391 | HFDP(12) - Compound Pattern | Compound Pattern is to combine two or more patterns to solve a general problem. One of the most... | 21,253 | 2024-05-29T16:21:30 | https://dev.to/jzfrank/hfdp12-compound-pattern-2e2b | Compound Pattern is to combine two or more patterns to solve a general problem. One of the most famous compound pattern is the MVC (model view controller) pattern.
MVC involves Model, View, and Controller. When user touch a button, it will invoke controller to do certain things. The controller then invoke the model to modify its state. Finally, the model will notify the view that something changes. The view will be rendered accordingly.
Learning MVC from top down is a bit involving. However, learning it from bottom up is very simple. MVC is nothing but a combination of patterns.
The controller and the view are using the `Strategy pattern`. The view does not care the concrete behavior, it just invokes the controller. A concrete controller is just an implementation of an interface and could be easily replaced by another implementation.
The model and the view are using the `Observer pattern`. The model is the Observable and the view is the Observer. The model could notify the subscribed view the changes of its status. The observer view will update the view accordingly.
The view itself is using the `Composite pattern`. Consider the relationship between a window and a button. They are both visual elements but have an inclusive relation. A view could be a standalone or could contain other views.
Sometimes we want to reuse a controller. Often we need to use Adapter pattern to adapt the interface.
MVC pattern is so useful that it gets adapted and used in many popular frameworks. In the web world, a thin client approach is where the model, most of view, and the controller all reside in the server, while the browser renders the view. Single Page Application approach is all the model, view and controller reside in the browser. Most frameworks lie in between the two extremes.

1,873,037 | RESTful APIs: Fundamentos, Práticas e Implementação | Introdução As APIs RESTful são um componente essencial do desenvolvimento web moderno,... | 0 | 2024-06-01T13:45:00 | https://dev.to/thiagohnrt/restful-apis-fundamentos-praticas-e-implementacao-gle | webdev, restapi, fullstack, braziliandevs | ## Introdução
As APIs RESTful são um componente essencial do desenvolvimento web moderno, permitindo que diferentes sistemas se comuniquem de forma eficiente e escalável. Este artigo explorará os fundamentos das APIs RESTful, as melhores práticas para sua implementação e exemplos práticos de como criar uma API RESTful.
### 1. O Que São APIs RESTful?
APIs (Application Programming Interfaces) são conjuntos de regras que permitem que diferentes aplicações se comuniquem. O REST (Representational State Transfer) é um estilo de arquitetura para projetar redes de aplicativos que utilizam os princípios da web. Uma API que segue os princípios REST é chamada de API RESTful.
### 2. Princípios do REST
Para ser considerada RESTful, uma API deve seguir seis princípios arquiteturais:
1. **Cliente-Servidor**: A separação entre cliente e servidor melhora a portabilidade do cliente em diferentes plataformas e a escalabilidade do servidor.
2. **Stateless**: Cada requisição do cliente ao servidor deve conter todas as informações necessárias para entender e processar o pedido. O servidor não armazena nenhuma informação sobre o estado do cliente entre as requisições.
3. **Cacheável**: As respostas devem ser explicitamente rotuladas como cacheáveis ou não, para evitar que clientes reutilizem dados desatualizados.
4. **Interface Uniforme**: A aplicação de uma interface uniforme simplifica e desacopla a arquitetura. Isso geralmente é implementado com os métodos HTTP padrão (GET, POST, PUT, DELETE).
5. **Sistema em Camadas**: Uma arquitetura REST pode ser composta de camadas hierárquicas, onde cada camada não conhece as camadas além daquela com a qual está interagindo.
6. **Código Sob Demanda (opcional)**: A funcionalidade pode ser estendida pelo envio de código executável do servidor para o cliente quando necessário.
### 3. Métodos HTTP Comuns
Os métodos HTTP são utilizados para realizar operações específicas em recursos. Os métodos mais comuns são:
- **GET**: Recupera dados de um recurso.
- **POST**: Envia dados para criar um novo recurso.
- **PUT**: Atualiza um recurso existente.
- **DELETE**: Remove um recurso.
### 4. Estrutura de uma API RESTful
Uma API RESTful bem projetada segue uma estrutura organizada e consistente. Aqui estão alguns elementos essenciais:
#### 4.1. Endpoints
Os endpoints são as URLs onde os recursos podem ser acessados. Devem ser intuitivos e representativos dos recursos que manipulam. Por exemplo:
- `/users` - Endpoint para gerenciar usuários.
- `/products` - Endpoint para gerenciar produtos.
#### 4.2. Paths e Verbos
Os paths dos endpoints devem ser nomeados com substantivos no plural, e os métodos HTTP (verbos) devem indicar a ação a ser realizada. Exemplos:
- `GET /users` - Retorna uma lista de usuários.
- `POST /users` - Cria um novo usuário.
- `GET /users/{id}` - Retorna os dados de um usuário específico.
- `PUT /users/{id}` - Atualiza os dados de um usuário específico.
- `DELETE /users/{id}` - Remove um usuário específico.
#### 4.3. Status Codes
Os códigos de status HTTP informam ao cliente o resultado da requisição:
- **200 OK**: Requisição bem-sucedida.
- **201 Created**: Recurso criado com sucesso.
- **204 No Content**: Requisição bem-sucedida, mas sem conteúdo para retornar.
- **400 Bad Request**: Requisição inválida.
- **401 Unauthorized**: Autenticação necessária.
- **404 Not Found**: Recurso não encontrado.
- **500 Internal Server Error**: Erro no servidor.
### 5. Boas Práticas
Para garantir que sua API RESTful seja eficiente e fácil de usar, siga estas boas práticas:
#### 5.1. Nomenclatura Consistente
Use uma nomenclatura clara e consistente para endpoints e recursos. Utilize substantivos no plural para paths e mantenha uma estrutura uniforme.
#### 5.2. HATEOAS (Hypermedia As The Engine Of Application State)
Incorpore links nos recursos retornados pela API para descrever como os clientes podem navegar pela API. Isso torna a API mais intuitiva e autoexplicativa.
#### 5.3. Documentação
Documente sua API de forma abrangente e clara. Ferramentas como Swagger/OpenAPI podem gerar documentação interativa e facilitar o uso por desenvolvedores.
#### 5.4. Autenticação e Autorização
Proteja sua API com mecanismos adequados de autenticação (como OAuth) e autorização para garantir que apenas usuários legítimos possam acessar os recursos.
### 6. Exemplo Prático
Vamos criar um exemplo simples de API RESTful usando Node.js e Express.js.
#### 6.1. Configuração Inicial
1. Crie um novo projeto Node.js:
```sh
mkdir api-example
cd api-example
npm init -y
npm install express
```
2. Crie um arquivo `index.js` e adicione o seguinte código:
```js
const express = require('express');
const app = express();
const port = 3000;
app.use(express.json());
let users = [
{ id: 1, name: 'John Doe' },
{ id: 2, name: 'Jane Doe' },
];
// GET /users
app.get('/users', (req, res) => {
res.json(users);
});
// GET /users/:id

This guide provides an overview of the current road conditions and essential travel tips for a safe and enjoyable trip.https://iamnavigato.com/road-conditions-guide-for-spiti-valley-trip/
Current Road Conditions
Key Routes to Spiti Valley
Shimla to Spiti (via Kinnaur)
Road Status: Generally open year-round, barring heavy snowfall or landslides.
Condition: The road from Shimla to Kinnaur is relatively well-maintained, but the stretch from Kinnaur to Spiti can be challenging with narrow paths, steep ascents, and potential landslide-prone areas.
Manali to Spiti (via Rohtang Pass and Kunzum Pass)
Road Status: Typically open from June to October.
Condition: This route is more adventurous but also riskier. Rohtang Pass and Kunzum Pass are high-altitude passes with rugged terrain. The road is often rocky and can be affected by snow and ice, making it tricky to navigate.
Internal Roads in Spiti Valley
Kaza to Key Monastery and Kibber: Well-maintained, but narrow and steep.
Kaza to Tabo and Dhankar: Mixed conditions with some well-paved sections and some rough patches.
Kaza to Pin Valley: Generally good but can have muddy and slippery areas during the monsoon season.
Travel Tips for Spiti Valley Road Trip
Preparing Your Vehicle
Vehicle Choice: A 4x4 vehicle or a sturdy SUV is recommended. Ensure your vehicle is in excellent condition, with good tires and a robust suspension system.
Fuel: Fuel stations are sparse. Top up your tank at every opportunity, especially in major towns like Manali, Kaza, and Reckong Peo.
Spare Parts and Tools: Carry essential spare parts, including extra tires, fan belts, and a comprehensive tool kit. Knowing basic repair skills can be incredibly helpful.
Packing Essentials
Clothing: Pack layers to manage the varying temperatures. Warm clothing, waterproof jackets, and sturdy shoes are a must.
Health and Safety: Carry a well-stocked first-aid kit, including medicines for altitude sickness. Oxygen cans can be lifesavers in high-altitude areas.
Food and Water: Stock up on non-perishable snacks and bottled water, as restaurants and shops are not always readily available.
Accommodation
Homestays: Spiti Valley offers numerous homestays, providing a closer look at local culture. Booking in advance during peak seasons is advisable.
Guesthouses and Hotels: Available in major towns like Kaza, Tabo, and Kalpa. They offer basic amenities, but luxury should not be expected.
Camping: For the adventurous, camping is an option, but ensure you are equipped with the right gear to handle the cold nights and potential wildlife.
Health and Safety Precautions
Altitude Sickness: Acclimatize gradually by spending a couple of days in places like Manali or Shimla before ascending to higher altitudes. Stay hydrated and avoid strenuous activity initially.
Emergency Contacts: Keep a list of emergency contacts, including local authorities, hospitals, and your country's embassy or consulate.
Weather Updates: Check weather conditions regularly. Sudden weather changes can lead to road closures, especially at high-altitude passes.
Things to Do in Spiti Valley
Monasteries: Visit ancient monasteries like Key Monastery, Tabo Monastery, and Dhankar Monastery. These spiritual hubs offer tranquility and insight into Buddhist culture.
Adventure Activities: Engage in trekking, camping, and exploring lesser-known trails. The Pin Valley National Park offers excellent opportunities for wildlife spotting.
Cultural Immersion: Interact with the locals, experience traditional Spitian cuisine, and participate in local festivals if your visit coincides with one.
Environmental Responsibility
Spiti Valley is a fragile ecosystem. Respect the environment by following these guidelines:
No Littering: Carry all your trash back with you. Use biodegradable products whenever possible.
Stay on Marked Trails: Avoid off-roading to protect the local flora and fauna.
Water Conservation: Use water sparingly. Many regions in Spiti face water shortages, especially during the dry months.

1,873,032 | Day1 #90daysofdevops | 1. What is DevOps? DevOps combines cultural philosophies, practices, and tools to improve... | 0 | 2024-06-01T13:27:13 | https://dev.to/oncloud7/day1-90daysofdevops-2pj0 | devops, day1, 90daysofdevops, automation | **1. What is DevOps?**
DevOps combines cultural philosophies, practices, and tools to improve collaboration and communication between software development and IT operations teams. This collaboration allows faster development cycles, improved software quality, and quicker response to customer needs.
Traditionally, development and operations teams worked separately. Developers would write the code, and then hand it off to operations to deploy and maintain it. This could lead to inefficiencies and friction between the two teams. DevOps breaks down these silos and encourages the two teams to work together throughout the entire software development lifecycle.
**2.What is Automation?**
Automation is the use of technology and tools to perform tasks and processes without human intervention.
It involves scripting or programming to automate repetitive and manual tasks, reducing the need for manual intervention and human error.
Automation can be applied to various areas, such as software testing, deployment, infrastructure provisioning, and monitoring.
By automating tasks, organizations can improve efficiency, reduce errors, and free up valuable time for teams to focus on more critical and creative work.
**3.What is Scaling?**
Scaling is the ability to handle increased workloads or accommodate growth without sacrificing performance or reliability.
In the context of software systems, scaling involves adding resources, such as servers or computing power, to handle higher demands.
Scaling can be achieved vertically (scaling up) by increasing the capacity of individual resources, or horizontally (scaling out) by adding more resources in parallel.
Effective scaling ensures that software applications can handle increased user traffic, data processing, or other workloads while maintaining optimal performance.
**4.What is Infrastructure?**
Infrastructure is the underlying foundation or framework that supports software applications and services.
It includes hardware, servers, networks, storage, and other components required to host and run software systems.
In the context of DevOps, infrastructure can also include cloud-based services, virtualization, containers, and other technologies.
Infrastructure needs to be scalable, reliable, and flexible to meet the changing demands of software applications.
**5.Why DevOps is Important?**
1. Faster time to market
2. Improved collaboration
3. Continuous integration and delivery
4. Increased reliability
5. Enhanced quality
6. Scalability and flexibility
7. Cost savings

Use a `trigger` provided react-hook-form and call this in custom submit method.
This approach is using basic JavaScript.
```tsx
const formSchema = z.object({
name: z.string(),
});
const Form = () => {
const { register, trigger } = useForm<z.infer<typeof formSchema>>({
resolver: zodResolver(formSchema),
});
const onSubmit = async (e: React.FormEvent<HTMLFormElement>) => {
const isValid = await trigger();
if (!isValid) {
e.preventDefault();
return;
}
// if you want to add something to the form, you can write it here.
};
return (
<form onSubmit={onSubmit}>
<input {...register('name')} />
<button type="submit">Submit</button>
</form>
);
};
```
I develop the react application on MPA, so I needed to send a form by not ajax. | cojiroooo |

1,873,028 | An exercise in semantics - Method vs Function | In the programming terminology, we often encounter the terms method and function. Let's engage in an... | 0 | 2024-06-01T13:21:30 | https://dev.to/yannick555/an-exercise-in-semantics-method-vs-function-23gn | programming, theory, semantics | In the programming terminology, we often encounter the terms *method* and *function*. Let's engage in an exercise in semantics, broadening our understanding to consider the contextual nuances that shape both terms.
In many programming languages, such as JavaScript or Python, modules or namespaces provide a structural framework for organising code and enforcing encapsulation. Within these constructs, functions can be grouped together, forming cohesive units of functionality within a specific context. It is within this context that we propose a reevaluation of terminology.
## TL;DR
In OOP, a *method* is a function that is associated with an object.
In a more general form: In programming, a *method* is a function that is related to a context and whose visibility/accessibility is restricted by that context, where *context*, *relation to the context* and *visibility/accessibility restriction* all depend on the specific programming language considered.
## Introduction
The terms *method* and *function* are often used interchangeably, but there are key differences between them, especially in object-oriented programming (OOP). The following sections provide a detailed comparison.
## Function
- **Definition**: A function is a block of code designed to perform a specific task. It is defined independently and can be called with parameters to execute its task.
- **Context**: Functions are not inherently associated with any object. They can be standalone or part of a module.
- **Usage**: Functions are used to encapsulate reusable code and can be called from anywhere in the program if they are in scope.
- **Syntax Example** (in Python):
```python
def add(param1, param2):
# function body
return param1 + param2
```
## Method
- **Definition**: A method is a function that is associated with an object. In OOP, methods define the behaviours of an object and can operate on data contained within the object (its attributes).
- **Context**: Methods are defined within a class and must be called on an instance of that class (or the class itself for class methods).
- **Usage**: Methods are used to manipulate the data of an object and to perform operations related to that object. They can access and modify the object’s state.
- **Syntax Example** (in Python):
```python
class MyClass:
def add(self, param1, param2):
# method body
return param1 + param2
# Creating an instance of MyClass
obj = MyClass()
# Calling the add method on the object
result = obj.add(1, 2)
```
## Key Differences
1. **Association**:
- **Function**: Independent, not tied to any object.
- **Method**: Bound to an object (instance method) or a class (class method/static method).
2. **Self Parameter (Python Specific)**:
- **Function**: No implicit parameter.
- **Method**: The first parameter is typically `self` for instance methods, which refers to the instance of the class.
3. **Calling**:
- **Function**: Called directly by its name (if in scope) or via module reference.
- **Method**: Called on an instance or class.
4. **Scope**:
- **Function**: Can be globally scoped or limited to a specific module.
- **Method**: Scoped within the class definition and often interacts with the instance's attributes and other methods.
## The case of static methods in Java
Given the definition of a method provided supra, one may wonder why static methods in Java should be called *method* instead of *function*: static methods are indeed not linked to an object.
In Java, static methods are linked to a class rather than an instance of the class, but they are still considered methods for several reasons rooted in object-oriented programming principles and terminology:
### 1. **Context and Namespace**
- **Class Context**: Static methods belong to the class's namespace and are defined within the class body. Even though they do not operate on an instance of the class, their definition within the class ties them to the class's scope.
- **Encapsulation**: By being part of the class, static methods help encapsulate functionality that is logically related to the class but does not require access to instance-specific data.
### 2. **Access and Usage**
- **Access**: Static methods are called using the class name, reflecting their association with the class. This usage pattern reinforces their identity as methods within the class. Private static methods may be called from non-static methods of the same class, reinforcing the conceptual link between a static method and instances of its containing class.
- **Functionality**: Static methods can access other static methods and static variables of the class. This capability aligns with the class-level context and differentiates them from standalone functions.
### 3. **Terminological Consistency**
- **Method**: In OOP, the term *method* is used to describe functions that are defined within a class, regardless of whether they operate on instances or not. This convention maintains consistency in terminology.
- **Class Methods**: Similarly, class methods are also considered methods because they are associated with the class and can access class-level data and methods. Static methods fit this conceptual framework.
### Example to Illustrate the Concept
Here's a Python example to illustrate how static methods fit within a class:
```python
class MathUtility:
# A static method
@staticmethod
def add(a, b):
return a + b
# Another static method
@staticmethod
def subtract(a, b):
return a - b
# Calling static methods using the class name
result1 = MathUtility.add(5, 3)
result2 = MathUtility.subtract(10, 4)
print(result1) # Output: 8
print(result2) # Output: 6
```
Thus, even though static methods do not operate on instances, their definition within a class and their role in encapsulating class-related functionality justify their classification as methods rather than standalone functions.
## My opinion
I would argue that the link to an object or a class may be a bit too restrictive, when using the term *method*.
Consider expanding the context beyond objects and classes to include modules or namespaces. In many languages, modules or namespaces provide a way to group related functions and restrict their visibility from outside contexts. This grouping can enforce encapsulation and modularity in a manner similar to classes.
The key is understanding that what distinguishes a *method* from any other kind of function is the relation to some context as well as a visibility/accessibility specific to that context.
`Note that I do not further define what the kind of the relation should be, given that it may differ with many languages, and given that any further specification may not be general enough to be compatible with the constructs of all existing or future languages.`
For instance, in JavaScript or Python, functions defined within a module or namespace can be considered methods of that module if they are meant to operate within its context. These functions might not belong to a specific object or class, but they are still tied to the module's scope and restricted in their visibility and access.
Therefore, it might be appropriate to use the term _method_ instead of _function_ in such contexts. The essential characteristics that differentiate methods from functions—namely, the contextual association and restricted visibility—are present, but at the level of a module or namespace rather than an individual object or class.
By broadening our perspective, we can recognise that methods do not need to be limited to the traditional object-oriented paradigm. Instead, they can exist within any structured context that enforces scope and encapsulation, whether it be a class, module, or namespace.
## Summary
While, by definition, as methods are a special kind of function, both functions and methods perform similar roles by encapsulating code for reuse, methods are functions that live inside objects and are meant to operate on the data contained within those objects. Functions are more general-purpose and not tied to any particular data structure. | yannick555 |

So I'm back after two days of missing my streak of posting here, but I did not miss a day of development. Still, I'm counting my progress according to the days I post here so day 7 it is. I'm done implementing logic and visualization of stack, queue, and linked list on my DSA visualizer project and it has been really fun. I also refactored the code a little bit and redefined the whole file structure of the application more clean and stream lined.
**What's next?**
I will be moving on to binary search tree and will do the same for like I did with other structures. Although I really want to push the boundary of animation and visualization of structures but for now I wanna get the basic add and remove functionality to it and later put on extra time to polish it up.
**Improvements required**
I really want to take time with this one and basically make it as efficient and fun to use as possible in terms of visuals and functionality. I really want to add sorting functionality for each structure and present them in a way it is fun to visualize. I do have some ideas on how to get there but if there are recommendations, feel free to write down.
Wish me luck! | zain725342 |

1,872,949 | Currying in JavaScript | What is Function Currying in JavaScript ? 🙄🙄 Currying is an advanced technique of working... | 0 | 2024-06-01T12:56:16 | https://dev.to/mrhimanshusahni/currying-in-javascript-20d5 | javascript, programming, learning, webdev | ## What is Function Currying in JavaScript ? 🙄🙄
**Currying** is an advanced technique of working with functions. It’s used not only in JavaScript, but in other languages as well.
It is a technique in functional programming, that transforms the function of multiple arguments into several functions of a single argument in sequence.
The translation of function happens something like this,
Currying is a transformation of functions that translates a function from callable as `f(a, b, c)` into callable as `f(a)(b)(c)`.
<u>**Please note: Currying doesn’t call a function. It just transforms it.**</u>
**How to achieve Currying in JavaScript?**
Currying is not built-in by default in JavaScript. We can implement currying by following the ways
- It can be achieved by using the **`bind()`** method.
- It can be achieved by using the **closures**.
- Using Third-party libraries such as **Lodash**.
1) Currying using **`bind()`** method
2) Currying using **closures** in JavaScript
3) Currying using Third-party Library **Lodash**

**Why is currying useful in JavaScript**
1. **Code re-usability**: Curried functions can be used to create reusable code that can be used in different contexts. Since curried functions can be partially applied, they can be reused with different arguments to create new functions.
2. **Improved code readability**: Curried functions can make code more readable and expressive by breaking down complex logic into smaller, more manageable pieces. This can make it easier for developers to understand and maintain code.
3. It helps us to avoid passing the same variable multiple times.
4. **Promotes functional programming**: Currying is a key concept in functional programming, and using curried functions in your code can promote functional programming practices.
5. It reduces the chances of error in our function by dividing it into multiple smaller functions that can handle one responsibility
**Noted Points: The currying requires the function to have a fixed number of arguments.**
> A function that uses rest parameters, such as **`f(...args)`**, can’t be curried this way.
---
## Summary
Currying in JavaScript is a technique that does the transform and makes `f(a,b,c)` callable as `f(a)(b)(c)`.
## Conclusion
Currying is a great technique that can bring many benefits to JavaScript programming.
By using the currying technique, you can create more **re-usable**, **maintainable**, and **modular code** that is better suited to the challenges of modern web development.

The goal is to help you understand... | 0 | 2024-06-01T12:55:14 | https://dev.to/shehzadhussain/why-is-front-end-development-so-complicated-3g8o | webdev, javascript, beginners, programming | Is front-end development too complex? Today, we'll talk about it.
The goal is to help you understand today's front-end development.
Front-end development is important for any developer. It affects how well web apps work.
Many developers find modern front-end frameworks hard to use. This is because technologies change quickly, and web apps need to be:
- **fast**
- **interactive**
- **easy to maintain**
## Front-end development has become more complex over the years.
Front-end development has changed a lot since the days of jQuery. New frameworks like Angular, React, and Vue have introduced new challenges:
- **State Management**: The web is stateless, so we need strong solutions to manage the state. Angular and React tried to solve these issues but brought their problems.
- **Dependencies**: Many dependencies and tools make project setup harder. While useful, they need regular maintenance. Abandoned packages can also cause issues.
- **SEO and Performance**: Modern frameworks must have good SEO and fast loading times.
- **Web evolution**: Web apps now aim to be as engaging as mobile apps, driving complexity.
- **Complex Modern frameworks**: There are many frameworks available to use.
## State Management Evolution
In the past, managing state in web apps was simple but limited. As apps got more complex, **we needed better state management**. Angular offered a complete solution but it was heavy and complex.**React provided a simpler, component-based approach**.
This example shows how React’s useState hook makes state management easy.
## The Dependency Dilemma
Modern front-end projects have many dependencies. They bring great features but you need to manage and update them often. Tools like Webpack and Babel add complexity but are essential.
Managing dependencies is simple. But, you have to keep an eye on updates and compatibility.
## Where to start in front-end development?
First, **master the fundamentals** and then...
I strongly recommend **React**. It's one of the best and most popular front-end frameworks.
React is a safe bet!
## React Developer Roadmap in 6 Simple Steps
1. HTML, CSS, and JavaScript fundamentals
2. Git version control system
3. React fundamentals
4. State management
5. API interaction
6. Testing
## Conclusion
**Front-end development is more complex now**. It's the truth. Yet, this complexity meets the needs of modern web apps.
**Mastering current tools is key to building strong, high-performing web apps**.
Stay willing to learn, improve, and build awesome apps!
Please, comment on your thoughts. Your thoughts are valuable to contribute to the front-end development field. All are welcome! I want to hear them.
Keep up the good work! :) | shehzadhussain |

1,873,008 | On Writing Good Code | Over the years I have realized that delivered code is light-years better than beautiful but useless... | 0 | 2024-06-01T12:39:21 | https://primalskill.blog/on-writing-good-code | webdev, beginners, architecture, programming | Over the years I have realized that delivered code is light-years better than beautiful but useless code. This of course is not to belittle the "code artists" I look up to who have the mental capability to deliver "JIT code" that is also clean, beautiful, and reads like a good novel.
So what about the rest of us? What can we do to make our code just that tiny bit better for our future selves and colleagues who will maintain it?
I have gathered a few principles, North Stars if you will, to guide me along this journey, and the first is that:
> Programs must be written for people to read, and only incidentally for machines to execute. -- Hal Abelson
Even though code will ultimately be interpreted and executed by machines, the code base itself should always be written with humans first in mind.
I have never successfully got my way around in a code base that wasn't readable and the [code architecture could easily be reasoned about](https://primalskill.blog/wins-and-trade-offs-in-software). There's something beautiful when reading well-written code, the execution path flows in our mind like well-composed music.
> A long descriptive name is better than a short enigmatic name. A long descriptive name is better than a long descriptive comment. -- Robert C. Martin
There are always two camps of people when we're talking about software, and the idea above is no exception. In the past developers and mentors always told new programmers to have small variable names, functions, and constants.
This, like everything else, in programming is nuanced and can be interpreted in multiple ways. Yes, when variables don't have any meaningful underlying logic behind them and are ephemeral such as a counter variable in a loop, by all means, should have short names.
Anything else should instantly let the reader know what it is about, a function called `UpdateProductStatusCode` is leaps and bounds better than a function called `updProd` or `upd_prod_st`.
Also, the second part of the quote A long descriptive name is better than a long descriptive comment refers to the fact that if a developer has to write a long comment to explain what a function or code block is about is usually a "code smell" to refactor the code. Explaining complex code flows is still encouraged though, I like writing long comments to explain what a function does if the execution path is complicated.
> Code is read more than it is written. -- Daniel Roy Greenfeld
I've written more about this concept in this [blog post here](https://primalskill.blog/code-is-read-more-than-it-is-written).
This quote underlines the idea that the majority of developers' time is spent understanding code and only incidentally spending time writing code. I could argue that writing code is just a side effect of thinking deeply about a solution to a very specific software problem.
> Don't comment bad code, rewrite it. -- Brian Kernighan
Commenting a badly written piece of code is lazy, but not everybody has the luxury of time to refactor code often, but nonetheless, everybody should strive for it.
Production code is inherently messy and always in need of refactoring, commenting, and explaining why a poorly written function does what it does is always encouraged in my opinion when you don't have the necessary resources to improve it.
> In programming, boring and simple is always better than smart and complex. -- Rob Pike
A straightforward and simple solution is always preferable because it is easier to understand, maintain, and debug. Simple code is more accessible to other developers who may need to work on it in the future, reducing the likelihood of introducing bugs or errors.
Complex solutions, while they might seem clever or efficient, can introduce unnecessary complications, making the code harder to read or build on top of. Complex code can become a maintenance burden, as it needs more time to understand.
I will always choose the [simple, boring, and battle-tested tech.](https://primalskill.blog/its-probably-fine) over the latest and newest shiny thing as I mentioned at the beginning of this article that delivered code is better than beautiful code that misses the deadline.

## What I Built
<!-- Tell us what you built and what you were looking to achieve. -->
I built a sort of minimal modern website. I hoped to free up space and condense it down into a small carousel to make it easier to navigate. I also wanted the gradients to feel like sunsets, as when most people think of beaches, sunsets go along with them.
## Demo
<!-- Show us your project! You can directly embed an editor into this post (see the FAQ section from the challenge page) or you can share an image of your project and share a public link to the code. -->
{% codepen https://codepen.io/SalladShooter/pen/NWVpbNV %}
## Journey
<!-- Tell us about your process, what you learned, anything you are particularly proud of, what you hope to do next, etc. -->
In the beginning I played around with what HTML was given, and planned out what I sort of wanted it to look like. I focused on the CSS for most of the challenge, but used a little JavaScript to add a little bit of styling to the HTML elements without editing it. During this process I learnt a lot about clipping masks and radial gradients in the CSS, as that was something I had never done. I am proud of the header looking like a sunset to a beach. I hope to take these skills and apply them to upcoming projects, and revise current ongoing ones.
I hope you like what I have made for the June DEV Frontend Challenge! | salladshooter |

To complement the official course, I turned to YouTube tutorials. These bite-sized lessons were a lifesaver, offering flexibility to learn at my own pace. Channels like "Azure Academy" and "John Savill's Technical Training" broke down complex concepts into manageable chunks. The visual and auditory learning style of these tutorials helped reinforce my understanding and provided practical insights that were often missing from the official materials.

### Practical Experience
Theory alone isn't enough; practical experience is crucial. I carved out time to experiment with Azure's free tier, setting up virtual machines, deploying web apps, and exploring various Azure services. This hands-on practice was invaluable. It turned abstract concepts into tangible skills, solidifying my understanding and boosting my confidence.
Edusum.com Practice Tests
Despite my progress, I still felt the need for a comprehensive assessment of my preparedness. This is where Edusum.com came into play. The site offers over 1000 practice questions tailored to the AZ-900 exam, covering every topic in depth. The quality and variety of these questions were impressive, mimicking the style and difficulty of the actual exam.
Taking these practice tests was like undergoing a series of rigorous training sessions before a big game. Each test highlighted my strengths and pinpointed areas that needed more attention. The detailed explanations for each question were particularly helpful, providing insights into why a particular answer was correct or incorrect.
### Preparation Strategy:
Balancing study time with a full-time job was challenging but manageable. I developed a study routine that fit my schedule, dedicating early mornings and weekends to focused study sessions. This consistency, even if for shorter durations, made a significant difference. Using Edusum.com's mobile-friendly platform, I could even squeeze in a few practice questions during lunch breaks or while commuting.
As the exam date approached, I ramped up my preparation, focusing on areas where I felt less confident. I revisited the official course, rewatched key YouTube tutorials, and retook Edusum.com practice tests. The night before the exam, I reviewed my notes and did a final round of [practice questions](https://www.edusum.com/microsoft/az-900-microsoft-azure-fundamentals) to ensure everything was fresh in my mind.
## Passing the AZ-900 Exam
The moment of truth arrived, and I felt prepared. Thanks to the comprehensive preparation strategy and the invaluable practice tests from Edusum.com, I passed the AZ-900 exam with flying colors. The structured approach, combined with diverse learning resources, was key to my success.
In a Nutshell: The Secret to Success
Passing the AZ-900 exam amidst a busy professional life is undoubtedly challenging, but it's achievable with the right strategy. The combination of official training, YouTube tutorials, hands-on practice, and the exhaustive practice questions from Edusum.com proved to be the perfect formula. For anyone looking to conquer this exam, I highly recommend integrating Edusum.com's practice tests into your study routine. They provide not just preparation, but the confidence to succeed.

Since the release of ChatGPT, there has been a surge in interest in AI automation. When it comes to automation, AI Agents take the first seat. From Robots to self-driving cars to software systems, AI agents hold the potential to transform our world as we know it. With the continuous improvements in frontier AI models, these agents are becoming more capable and versatile.
However, despite all the hype and speculation, we are still in the early era of AI Agents, and building reliable and useful agents is challenging. A significant amount of effort is being dedicated to developing infrastructures, AI architectures, frameworks, and tooling ecosystems for creating reliable agents. This is similar to the early 90s era of the internet when foundational technologies were being built to support the massive growth and innovation that followed. As we stand at the cusp of this transformative era, now is the perfect time to learn about AI, AI agents, and the tools driving this revolution.
This article will explore what AI agents are, the different types of agents and their workflows, and provide real-world examples, and resources to help you build your own AI agents.
## Learning Objectives
- Understand what AI agents are.
- Explore different types of AI agents.
- Discover the key components of AI agents.
- Learn about AI agent workflows.
- Explore practical use cases of AI agents with examples.
- Find out how Composio can help build reliable and useful AI agents in the wild.
## What are AI Agents?
AI agents are systems powered by AI models that can autonomously perform tasks, interact with their environment, and make decisions based on their programming and the data they process. The agents can receive input from their environment via sensors or software integrations, and with the help of the decision-making prowess of AI models, they can act to influence it. The input data could be texts, images, audio, or videos. The AI model, typically an LLM (Large Language Model) or an LMM (Large Multi-modal Model), is responsible for interpreting the data and taking the necessary steps to achieve a given task.
**Example:**
Consider a customer service AI agent for an e-commerce platform. This AI agent uses an LLM to understand customer queries received through text messages. When a customer asks about the status of their order, the AI agent interprets the text input, retrieves the relevant information from the order database, and provides an accurate response. If the query involves a product return, the agent can initiate the return process by interacting with the return management system, providing the customer with instructions and updates.
## **What are the key principles that define** agents in AI **?**
You must be wondering, Isn't software doing the same thing, that is autonomously completing pre-determined tasks? So, what is the difference between AI agents and traditional software?
AI agents run on powerful LLMs like GPT-4. These models are trained on human-generated data, including logical reasoning, math, and coding tasks. This enables them to understand context of the questions, make informed decisions, and adapt to new information in ways traditional software cannot.
For instance, OpenAI’s Figure robot is a humanoid robot that uses a multi-modal model to reason and execute tasks. The robot processes auditory and visual data from surroundings via the multi-modal AI model. The model then intelligently decides which course of action to take to accomplish a task. The agent does not need human guidance at every step of decision-making, it can take cues from previous states to plan further.
## Types of AI Agents
Now that you know, what AI Agents are, let’s dig a bit more and understand different types of AI Agents.
### 1. Simple reflex agents
The most basic AI Agent whose functionality is limited to pre-defined rules. The agent receives external stimuli via sensors and responds with a specific action based on condition-action rules.
- **Example** : In a thermostat, when the temperature drops below a certain threshold, it turns on the heater. It doesn't store past data or learn from new information.
### 2. Model-based reflex agents
These are similar to simple reflex agents but unlike the latter, they have advanced decision-making capabilities. Instead of following pre-defined rules, model-based reflex agents use an internal model of the world to understand the effects of their actions, allowing them to make more informed and flexible decisions.
- **Example** : a vacuum-cleaning robot. It maintains an internal model of surroundings while cleaning. Sensing dirt cleans the spot; when it sees an obstacle, it updates its map and chooses a new path.
### 3. Goal-based Agents
Goal-based agents are a step up from reflex agents. The agents are motivated by a specific goal. The agents evaluate multiple actions based on how well they help achieve the goal. The agents can plan ahead of time and take possible sequences of actions to accomplish the goal.
- **Example** : a self-driving car that navigates from point A to point B.
### 4. Utility-based Agents
Utility-based agents possess a sophisticated decision-making framework. These agents can evaluate the effectiveness and desirability of different outcomes. They assess various possible courses of action to complete a task and select the one that maximizes utility. Utility factors can include efficiency, cost, time, and risk.
- **Example** : An investment trading system that manages a portfolio of stocks. Instead of just aiming to increase the portfolio's value (a goal), it evaluates potential trades based on their expected return and risk (utility).
### 5. Learning Agents
Learning Agents as the name suggests learn from their past interactions to improve at a given task over time. It uses a problem generator to simulate new tasks, that help refine their decision-making abilities and adapt to new situations. This continuous learning process allows them to become more efficient and effective in their operations.
- **Example** : A social media recommendation engine starts by recommending popular content and over time, it starts recommending content based on previous interactions.
### 6. Multi-agent System
Multi-agent systems are required when the task requires coordination among other agentic systems. These systems allow multiple AI Agents to work in tandem by sharing states and data. These systems are useful when tasks are interconnected and the actions of one agent affect others.
- **Example:** A collaborative crew of AI agents that consists of a research agent, an analyst agent, and a coding agent. The research agent with access to knowledge bases can autonomously extract relevant information, the analyst agent will analyze the data and instruct the code agent to prepare graphs and plots summarizing the result.
## Components of Artificial Intelligence Agent Architecture
The architecture of an AI Agent depends on the specific application and requirements. The architecture can be physical, software-based, or a mix of both. So, let’s discuss the components of an agent system.
- **Sensors/Prompts** : The agent receives external stimuli via sensors or text prompts. A physical robotic agent perceives the surroundings via a camera, mic, proximity, RADAR, and other such sensors. The input could come from these sensors or be provided in text format for software-based systems. For example, data can be provided in JSON, XML, or other structured text formats.
- **Actuators/Tools:** The actuators and tools help the agent execute tasks in the real world. Robotic systems depend on wheels, hands, legs, etc, while software-based systems use tool integrations.
- **Processors/Decision-making system:** These handle inputs from sensors, analyze the data, and determine the appropriate actions to accomplish a given task. Usually, this is an AI model.
- **Knowledge Base:** For long-term memory, previous interactions, or any external data is stored in a database. This enables the agents to access external data as and when needed.
### Example: A self-driving car
- **Sensors** : A self-driving car uses LIDAR, RADAR, and a Camera to perceive its surroundings, and navigate traffic and other obstacles. It may receive voice instructions from passengers through a mic.
- **Actuators** : The car uses the steering wheel, brakes, and other mechanical components to drive.
- **Processors** : The car’s onboard computer will use an AI model to process input data to avoid obstacles and find optimal routes.
- **Knowledge Base** : The car may have databases for storing map data, route information, and other such data to aid in better navigation.
## How does AI Agents Work?
So far, you have learned what makes an AI Agent, the types of agents, and the different components of a typical AI Agent system. To summarize, AI Agents are systems that can dynamically interact with their environment with the help of sensors, actuators, AI Models, and Knowledge bases. Now you will learn how these components work together to achieve a goal.
- **Goal Initialization** : The first step of the process is to provide the LLM in the back end with the desired goal. The LLM processes the goal and acknowledges the objective.
- **Task Planning:** The LLM prepares a step-by-step task list to accomplish the job and starts searching for components to finish jobs.
- **Tool use:** The LLMs are provided with a set of tools, and depending on the task, they will pick appropriate tools to accomplish the task. For example, if the task requires gathering information from the web, the LLM will choose a tool to surf the internet and collect data.
- **Data Storing and Accessing:** If the data needs to be saved on disk or in a database, the agent will select a tool to store the data in the appropriate format. The agent can also access data systems for task execution. For example, an AI Agent can retrieve documents from a file system to process them for further downstream tasks like report generation.
- **Termination:** The workflow ends when predefined conditions are met. This can occur when the execution is complete, or when the agent lacks access to the necessary tools and reaches a threshold number of iterations.
This is the overall structure of typical agentic workflows.
## AI Agents Example
Let's explore some promising real-world examples of AI agents.
### Figure's Humanoid Robots
Figure, a robotics company supported by OpenAI, launched a humanoid robot powered by OpenAI's multi-modal GPT model. The robot perceives the environment via a camera, mic, and other sensors. When the robot receives the command, it uses the AI model’s reasoning and decision-making ability to understand the task and uses actuators to finish the job. The robot has also shown the capability to learn by seeing activities.
### Devin: The First AI Software Engineer
Devin from the Cognition Labs took the internet by storm when it showcased its remarkable software development skills. It could navigate the GitHub repository, fix codes, and many more. It showed 13.86% accuracy on the SWE bench, a benchmark for AI SWE tasks. After Devin, many open-source alternatives have emerged showing similar or better performance.
### Waymo Self-driving Cars
Google's Waymo has turned the vision of autonomous driving into reality, enabling cars to travel from point A to point B without human intervention. With advanced sensors, AI model, and learning systems, the cars can process their environment to navigate traffic, avoid obstacles, and reach their destination safely.

最近整`HTTP3`客户端时候，需要验证服务端证书，中间出了点小插曲，老是报错见上篇[文章](https://dev.to/shouhua_57/http3zhi-quictlsbao-cuo-unable-to-get-local-issuer-certificate-14ic)，问题解决了但是想到另外个问题，浏览器和客户端都是怎么验证证书的，我们都知道服务端给出证书，客户端根据本地的或者用户提供的根证书校验，但是系统根证书在哪儿，为什么我没有设置，他们就自动找到了？本文旨在根据这个问题，梳理Ubuntu系统自带证书库和浏览器的证书库。本文主要聚焦Ubuntu系统，但是其他系统的流程大致相似。
## 系统证书库
Ubuntu系统的证书目录位于`/etc/ssl/certs`, 根证书是`/etc/ssl/certs/ca-certificates.crt`。 其他平台的默认证书可以查看[golang源码文件](https://go.dev/src/crypto/x509/root_linux.go)。
查看`/etc/ssl/certs`发现里面有很多`pem`格式证书，这里就是系统根证书目录，我的机器上面有部分软链接到`/usr/share/ca-certificates/mozilla`（这个是系统读取`/etc/ca-certificates.conf`配置加入的）。文件`/etc/ssl/certs/ca-certificates.crt`是这些证书的合集，可以使用如下命令查看所有证书的`subject`
```bash
awk -v cmd='openssl x509 -noout -subject' '/BEGIN/ {close(cmd)}; {print | cmd}' < /etc/ssl/certs/ca-certificates.crt
```
### 系统证书更新
系统不建议我们自己手动证书到这个目录和文件中，那我们如何添加证书到系统呢？系统提供了命令`update-ca-certificates`
```bash
man 8 update-ca-certificates
```
根据manpage介绍，`update-ca-certificates`更新`etc/ssl/certs`和`ca-certificates.crt`。我们将`pem`格式证书以`.crt`后缀放到`/usr/local/share/ca-certificates`，一个证书一个文件，然后执行命令就会自动添加到根目录证书中。
### 寻找证书
刚才不建议咱们自己添加证书，因为其中有些步骤是看不见的，比如[c_rehash](https://www.openssl.org/docs/manmaster/man1/openssl-rehash.html)过程。寻找证书通过证书的`subject`，如果通过打开文件找到`subject`比对，那这样效率太低了，所以通过将证书的`subject`的hash值作为文件名，就可以提高寻找效率了，`rehash`就是干这个事。比如，我的系统中有个`Go_Daddy_Class_2_CA.pem`证书
```bash
ll /etc/ssl/certs | grep 'Go_Daddy_Class_2_CA'
# f081611a.0 -> Go_Daddy_Class_2_CA.pem 这个是rehash生成文件
# Go_Daddy_Class_2_CA.pem -> /usr/share/ca-certificates/mozilla/Go_Daddy_Class_2_CA.crt
```
可以通过以下命令看下hash值是否正确(当然是正确的)
```bash
openssl x509 -hash -fingerprint -noout -in $(readlink -f /etc/ssl/certs/Go_Daddy_Class_2_CA.pem)
# f081611a
# SHA1 Fingerprint=27:96:BA:E6:3F:18:01:E2:77:26:1B:A0:D7:77:70:02:8F:20:EE:E4
```
最后的`.0`是为了防止hash碰撞产生一样的值。
## OpenSSL
OpenSSL默认情况使用系统证书库
```bash
openssl version -d # 打印OpenSSL目录
ls -l $(openssl version -d | tr -d '"' | awk '{print $2}') # 查看OpenSSL目录内容
```
通过查看OpenSSL目录，里面的`certs`文件夹默认是软链接到`/etc/ssl/certs`。因此OpenSSL编写代码使用默认证书库就是系统证书库
```c
SSL_CTX_set_default_verify_paths(ssl_ctx);
```
## 浏览器
浏览器一般使用图形界面设置，但是我就觉得纳闷了，我在浏览器中设置了，但是根目录证书中没有，猜想肯定使用自己证书库，查找后确定是这样的。
`Firefox`和`Chrome`都使用`sqlite`存储用户导入证书，具体放在文件`cert9.db`中，早期放在`cert8.db`，这里咱们不溯源历史，有兴趣可以查看相关[文档](https://wiki.mozilla.org/NSS_Shared_DB)。同样，这个数据库不建议直接操作，浏览器都使用了[NSS_Shared_DB](https://wiki.mozilla.org/NSS_Shared_DB)管理数据库，提供了命令`certutil`操作，Ubuntu需要安装`libnss3-tools`
```bash
sudo apt install libnss3-tools
```
[Chromium源码文档](https://chromium.googlesource.com/chromium/src/+/master/docs/linux/cert_management.md#add-a-certificate)中有提供如何操作。
### 查找浏览器证书库地址
命令操作没啥问题，但是关键是制定证书的数据库地址。Ubuntu一般使用`snap`(尽管不想使用)按照`Chrome`，会放在snap目录`$HOME/snap/[chromium|firefox]`，如果没有snap目录，可以查看个人目录隐藏文件夹`$HOME/.pki/nssdb`，可能会不一样，可以通过查找方式查询：
```bash
find $HOME -type f -name 'cert9.db'
```
注意浏览器都是以用户(profile)形式生成`cert9.db`的，Chromium系列明显亲民点，可以使用比如`$HOME/snap/chromium/current`软链接到当前用户目录。
## JKS(Java Key Store)
在前面查看`/etc/ssl/certs`目录时，看到有个文件夹`java`，翻看资料后发现，`JAVA`平台可以使用自己的证书库，支持多种存储格式，JKS的store位于`$JAVA_HOME/lib/security/cacerts`或者`$JAVA_HOME/jre/lib/security/cacerts`，JKS使用JDK提供的工具`keytool`管理。JKS的store默认密码是`changeit`。
```bash
# find JAVA_HOME
export JAVA_HOME=readlink -f $(which java) | sed 's/\/bin\/java//'
# List
keytool -list -keystore $JAVA_HOME/lib/security/cacerts -storepass changeit | head -5
# OR
keytool -list -cacerts -storepass changeit | head -5
# Add
keytook -import -alias testCert -keystore $JAVA_HOME/lib/security/cacerts -file ca_cert.crt
```
## 有用知识
工具[mkcert](https://github.com/FiloSottile/mkcert)是cert操作相关的库，里面有上面的相关信息，有兴趣可以仔细查看阅读。

It works by removing the outer layer of skin and stimulating collagen production. However, it's less suitable for very sensitive or dark skin due to potential pigmentation issues.
Microdermabrasion: This is a mechanical exfoliation that removes the outermost layer of dead skin cells, ideal for dry and non-sensitive skin types.
3. Minimally Invasive Procedures:
Microneedling: This involves tiny needles that prick the skin, encouraging regeneration and collagen production. It’s generally safe for all skin types, including sensitive skin.
Fillers: Hyaluronic acid fillers can fill out shallow-to-moderate scars, suitable for all skin types but especially beneficial for those with less elastic skin.
Consultation with a Dermatologist
The next step is to consult a dermatologist who can provide tailored advice based on your skin type and the severity of your scarring. A professional can assess your skin’s condition, discuss your medical history, and recommend the most suitable treatment options.
Considerations for Treatment in Chennai
When choosing a clinic in Chennai, consider factors like the expertise of the dermatologist, the types of treatments offered, and the clinic’s reputation. It’s also worth considering the climate of Chennai; for example, some treatments may require limiting sun exposure, which can be challenging in such a sunny city.
Conclusion
Choosing the right acne scar treatment involves understanding your skin type, researching available treatments, and consulting with professionals. Whether it’s home remedies or advanced dermatological procedures, Chennai offers a plethora of options to help you achieve smoother, clearer skin. By carefully selecting the treatment best suited to your skin type and needs, you can effectively manage and reduce acne scars in Chennai, enhancing both your appearance and confidence.

1,872,938 | How to compile, deploy and interact with smart contracts using Apeworx(ape) and VS Code. | Today, we are going to write our smart contracts using Vyper and the Apeworx framework. We are going... | 0 | 2024-06-01T11:34:44 | https://dev.to/mosesmuwawu/how-to-compile-deploy-and-interact-with-smart-contracts-using-apeworxape-and-vs-code-4hie | smartcontract, vyper, apeworx, web3 | Today, we are going to write our smart contracts using Vyper and the [Apeworx](https://docs.apeworx.io/ape/stable/userguides/quickstart.html) framework. We are going to connect to the ethereum network using [Sepolia](https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://www.alchemy.com/faucets/ethereum-sepolia&ved=2ahUKEwjxiYmL67mGAxWk3QIHHTcoE8AQFnoECBUQAQ&usg=AOvVaw3SPRlvlGFEBx-iKOSKlCWU) via [Alchemy](https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://www.alchemy.com/&ved=2ahUKEwi0vP366rmGAxWb0AIHHVGFCHkQFnoECBsQAQ&usg=AOvVaw1UlSJxXmtPQHfkuY4FAfE8).
## Prerequisites
- python version later than 3.8
- pip installed
- metamask wallet already [set up](https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://www.alchemy.com/overviews/how-to-add-sepolia-to-metamask&ved=2ahUKEwi5ypf367mGAxWqwAIHHfYDCoUQFnoECCQQAQ&usg=AOvVaw1o5ZcnrWQSjj6vYco-pub4)
## Procedure
First, we are going to set up the development environment. Remember, when using windows, it's recommended to use WSL2 for development purposes. I am using Ubuntu for this tutorial.
- Let's create a project folder named `testing`.
`mkdir testing`
- Then, navigate through the folder: `cd testing`
- Create a virtual environment named `.venv`
`python3 -m venv .venv`and then, run `code .` to open vs code.
In the VS code terminal, activate the virtual environment by running `source .venv/bin/activate`
Next, we are going to install `apeworx` and all dependencies through a single command: `pip install eth-ape'[recommended-plugins]'`.
After a successful installation, we are now going to connect our project to the metamask wallet through creation of what is called an [account.](https://academy.apeworx.io/articles/account-tutorial.html)
- Run `ape accounts import meta_wallet`
In the above command, we have named our account 'meta_wallet'(you can name it anything you want). You'll then be prompted to enter `private key` and create a `passphrase` to encrypt your account.
```bash
Enter Private Key:
Create Passphrase to encrypt account:
Repeat for confirmation:
```
To enter private key, go to your metamask wallet and copy a private key and securely save it somewhere. Paste it into the terminal and please note that you won't be able to see it so, don't paste more than once.
For a passphrase, create something that you won't forget.
To confirm if your account has been imported, run `ape accounts list`.
One more last thing to do for a successful set up is adding the Alchemy-api-key to our settings.
Run `code ~/.bashrc` to open the bashrc file. In this file, add the following line of code("YOUR_ALCHEMY_API_KEY" with the actual api key from alchemy) to the bottom end of it: `export WEB3_ALCHEMY_API_KEY="YOUR_ALCHEMY_API_KEY"
`
**Note:** If you are running your program on a testnet, please make sure that your alchemy ethereum app is a testnet not a mainnet.
Good that we are now done with the set up process, let's go for the actual business.
We shall start by initializing a project by running `ape init`.
This creates creates a project structure including; .build(for storage of artifacts), scripts folder, tests folder, contracts folder, and the ape.config-yaml file.
First, in the contracts folder, let's create a new file named `hello.vy` and add the following code which returns "Helloo, World!".
```python
#pragma version ^0.3.10
# A simple Vyper contract
@external
def say_hello() -> String[14]:
return "Helloo, World!"
```
Next is to compile our code: `ape compile`.
Please note that after running the above command, a new file named `hello.json` is automatically created in the .build folder. This file contains the `abi` and `bytcode` of the contract.
Apart from abi, for our web3 library to be able interact with the deployed smart contract, it will need what we call a contract address and network. So, our next task is to create a another file named `deploy_hello.py` in the scripts folder for serving two purposes:
1. Deploying script
2. Saving or adding the contact address and network details to the already existing hello.json file.
```python
import json
from ape import project, accounts
def main():
# Load your account
account = accounts.load('meta_wallet')
# Deploy the contract
contract = project.hello.deploy(sender=account)
# Save the deployment details
build_file = '.build/hello.json'
with open(build_file, 'r') as file:
contract_json = json.load(file)
contract_json['networks'] = {
'sepolia': {
'address': contract.address
}
}
with open(build_file, 'w') as file:
json.dump(contract_json, file, indent=4)
print(f"Contract deployed at address: {contract.address}")
if __name__ == "__main__":
main()
```
Run `ape run deploy_hello --network ethereum:sepolia:alchemy` .
Congratulations if your deployment was a successful one.
Lastly, we are going to interact with our deployed smart contract using [web3.py](https://web3py.readthedocs.io/en/latest/quickstart.html) library. Create a `scripts/interact_hello.py` file and add the following code:
```python
import json
from web3 import Web3
# Define the path to the contract build file
contract_build_file = '.build/hello.json'
# Load the contract ABI and address from the build file
try:
with open(contract_build_file, 'r') as file:
contract_json = json.load(file)
contract_abi = contract_json.get('abi')
# Ensure the ABI is loaded
if not contract_abi:
raise ValueError("ABI not found in the contract build file.")
# Check for the 'networks' key and retrieve the address
networks = contract_json.get('networks')
if not networks:
raise KeyError("Networks key not found in the contract build file.")
# Replace 'sepolia' with the actual network name used during deployment
network_details = networks.get('sepolia')
if not network_details:
raise KeyError("Network details for 'sepolia' not found.")
contract_address = network_details.get('address')
if not contract_address:
raise ValueError("Contract address not found in the network details.")
except (IOError, ValueError, KeyError) as e:
print(f"Error loading contract build file: {e}")
exit(1)
# Connect to the Ethereum network (e.g., Sepolia via Alchemy)
provider_url = 'Your_alchemy_url'
web3 = Web3(Web3.HTTPProvider(provider_url))
# Ensure the connection is successful
if not web3.is_connected():
print("Failed to connect to the Ethereum network.")
exit()
# Create a contract instance
contract = web3.eth.contract(address=contract_address, abi=contract_abi)
# Call the hello() function
def call_hello():
try:
message = contract.functions.say_hello().call()
print(f"Contract message: {message}")
except Exception as e:
print(f"An error occurred: {e}")
if __name__ == "__main__":
call_hello()
```
Run `python scripts/interact_hello.py`
Output: `Contract message: Helloo, World!`
Wow! we have had our smart contract compiled, deployed and interacted with all in vs code. If you found this article helpful, don't hesitate to give me a like and please follow for more. Thank You!
