1,917,011 | GitHub Scams as a Business Model | Look carefully at the graph below. It displays the number of software developers that exists in the... | 0 | 2024-07-09T09:14:35 | https://ainiro.io/blog/github-scams-as-a-business-model | opensource, github | Look carefully at the graph below. It displays the number of software developers that exists in the world. In 2024 there are 28 million software developers world wide. You can [check it out for yourself here](https://www.statista.com/statistics/627312/worldwide-developer-population/).
[GitHub](https://github.com/) is a website for software developers. If you haven't heard about it, think of it like a community of software developers, where we can meet, share ideas, and publish open source projects we've been working on. Below are the total number of software developers over the years. As you can see, there are 28 million today.
For a software developer GitHub is brilliant. GitHub has tons of services for people like me. Most of these services are also free, so for me it's frikkin' brilliant. However, for people who don't code, it's about as useful as a goat in the back seat of a taxi. There's absolutely no reason what so ever why a person who is not a software developer would want to register and create an account with GitHub.
GitHub is not the only platform out there, and not all software developers are actively using a platform such as GitHub. A guesstimate would be that 50% of the world's software developers have actually created an account with GitHub. This implies that 14 million software developers have a GitHub account. However, GitHub has way more than 100 million registered users! Excuse me for my French here, but ...
> If there are 14 million software developers on GitHub, who the fuck are the remaining 86 million people?
Running some rough stats on the above, implies that 80% of all GitHub users have absolutely no idea what so ever about how to create software at any capacity. Maybe some 10% of these additional accounts can be contributed to project managers and web designers, but even accommodating for such numbers implies that 7 out of 10 GitHub accounts are either fake, or literally Supabase CEO's aunt Jenny (or something).
Registering a GitHub account is not illegal, so aunt Jenny is of course more than welcome to create an account over there - There are also no laws against clicking the star icon on individual projects at GitHub. However, the problem becomes real when open source projects are evaluated according to how many stars they have.
> Evaluating the quality of Open Source projects from how many Stargazers they have is the equivalent of counting your children by how many times you masturbated in the shower ...
Not only is it a useless metric, but it probably proves nothing besides that the project is _fundamentally useless_. Having many Stargazers on GitHub is kind of like having 500+ reviews on Amazon - It implies dick shit zilch!
## Social Ponzi Schemes
GitHub has been overrun by the same psychopaths that's been selling likes on Facebook, Twitter, and YouTube now for a decade. Yes, you can literally _purchase GitHub accounts and likes_! I don't want to link to these croks for obvious reasons, but you can probably manually figure out their URL I presume.
They're even running their site on Shopify, making their whole operation simply so absurd I'm not even sure how to comment on them ...
## It's all rubbish
I can barely login to Facebook anymore without seeing some AI chatbot provider with an ad having 11,365 likes, and 467 comments. This is course _"peculiar"_ once you realise their website is a single page site, looks like something created with Microsoft Word, for then to having been dumped and exported as HTML. Buying anything online today basically feels more like it used to feel like when you were buying snakeoil in the 1890s.
> You know the product is crap, while the sales guy tells you it'll cure all ailments - And once the sheriff comes around, he jumps on his horse and rides like the wind out of town to avoid being lynched - Which is what he actually deserves
## The cost to society
Let me ask you a simple question; When your daughter hits the break pedal on her car to avoid front colliding with a truck, who would you prefer having created the software that ensures the car actually slows down instead of speeding up.
1. Some high functioning autistic dude with glasses the size of coca cola bottles, who can't even gather the strength to speek to girls, because he's afraid of starting to stutter, and therefore spent 40 years coding instead of playing with his dick?
2. Or some dude with a nice tan, being a self-proclaimed _"AI expert"_ on LinkedIn, looking like Arnold Schwarzenegger on all his photos, with a master degree from _"The University of Bullshit and Rubbish"_, taught by _"Professor Hoax"_, claiming to having worked with 501 of all Fortune 500 companies, having increased their revenue by a quadrillion, effectively solely responsible for every single good piece of tech we've got in 2024?
Exactly ...
> Hey you, yes you - You that marketing psycho, who have now started infiltrating GitHub with your social scams. Just a friendly piece of advice; Maybe leave us devs alone with our little community, to avoid having satellites start dropping from the sky on to your house, resulting in your entire shit, including your life, ending up going down the toilet like the shit it's probably less worth than.
Just a friendly piece of advice ...
## PwC is **THAT** way!
Then you can go talk to the (other) scammers of the world, such as the four big ones, to sell in your garbage services, based upon prompt engineering ChatGPT, to have it create _"next level trading algos"_, inevitably turning everybody into riches that'll dwarf Elon Musk. However, the _real_ code is still ours, and you'd be smart to _keep it that way_ for a looong, looong, loooong time ...
So stay the fuck out of GitHub you psycho! Or shit might start to get real one of these days ...

This can include text, images, music, and even videos. The technology behind GenAI has seen rapid advancements, and it's becoming increasingly accessible to developers and enthusiasts alike. In this article, we'll explore what GenAI is, how you can start learning it, provide a practical example using Python and a pre-trained model from Hugging Face, and discuss its real-world applications and future impact.
## What is Generative AI?
Generative AI refers to a class of algorithms that can generate new data samples from a learned distribution. Unlike traditional AI models that classify or predict outcomes, GenAI models create. This could be writing a story, composing a piece of music, generating an image, or even simulating human conversations.
The most common techniques used in GenAI include:
- **Generative Adversarial Networks (GANs):** These models consist of two neural networks, a generator and a discriminator, that are trained together in a process that allows the generator to produce increasingly realistic data.
- **Variational Autoencoders (VAEs):** These models work by encoding data into a latent space and then decoding it back to reconstruct the input data. This latent space can be sampled to generate new data.
- **Transformers:** These models, particularly when used in natural language processing (NLP), can generate coherent and contextually relevant text based on given input. Examples include GPT (Generative Pre-trained Transformer) models.
## How to Start Learning Generative AI
### 1. Understand the Basics of Machine Learning
Before diving into GenAI, it's crucial to have a solid understanding of machine learning (ML) fundamentals. You should be comfortable with concepts like neural networks, backpropagation, and training algorithms. Resources like "Hands-On Machine Learning with Scikit-Learn, Keras, and TensorFlow" by Aurélien Géron can be extremely helpful.
### 2. Learn About Specific Generative Models
- **GANs:** Start with Ian Goodfellow's original paper on GANs and then explore resources like "GANs in Action" by Jakub Langr and Vladimir Bok.
- **VAEs:** Dive into the technical details with the original paper by Kingma and Welling. Tutorials and courses on platforms like Coursera and Udemy can also be helpful.
- **Transformers:** Read the original paper "Attention is All You Need" and follow up with articles and tutorials on more recent advancements like GPT-3.
### 3. Practical Implementation
Implementing models is the best way to understand their workings. Platforms like Google Colab provide an excellent environment for running and experimenting with ML models without needing a powerful local machine.
### 4. Explore Pre-trained Models
Hugging Face is a treasure trove of pre-trained models for various NLP tasks. They provide an easy-to-use interface and a vast library of models, which makes it an excellent resource for beginners and experts alike.

---
## Example: Using a Pre-trained Model from Hugging Face
Let's dive into a practical example. We'll use a pre-trained GPT-2 model from Hugging Face to generate text based on a given prompt.
### Step 1: Install the Necessary Libraries
First, ensure you have the necessary libraries installed. You can do this via pip:
```bash
pip install transformers
pip install torch
```
### Step 2: Load the Pre-trained Model
Next, we'll load the pre-trained GPT-2 model and its tokenizer from Hugging Face.
```python
from transformers import GPT2LMHeadModel, GPT2Tokenizer
# Load the pre-trained model and tokenizer
model_name = "gpt2"
model = GPT2LMHeadModel.from_pretrained(model_name)
tokenizer = GPT2Tokenizer.from_pretrained(model_name)
```
### Step 3: Generate Text
We'll use the model to generate text based on a given prompt. Here's how you can do it:
```python
# Define the prompt
prompt = "Once upon a time, in a land far, far away,"
# Encode the prompt
inputs = tokenizer.encode(prompt, return_tensors="pt")
# Generate text
outputs = model.generate(inputs, max_length=100, num_return_sequences=1)
# Decode the generated text
generated_text = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(generated_text)
```
### Step 4: Run the Code
When you run this code, the model will generate a continuation of the given prompt. For example, you might get something like:
```
Once upon a time, in a land far, far away, there lived a wise old owl who knew the secrets of the forest. The animals would come from near and far to seek the owl's advice. One day, a young rabbit approached the owl with a question...
```

1,916,981 | Delegated Types and and building the ultimate Kanban Board in Rails | We're getting ready to work on our Kanban Board feature. It's exciting as we haven't started a "big"... | 0 | 2024-07-09T08:44:38 | https://dev.to/adrianthedev/delegated-types-and-and-building-the-ultimate-kanban-board-in-rails-1jmn | rails, kanban, devtools, database | We're getting ready to work on our Kanban Board feature. It's exciting as we haven't started a "big" feature in a while.
As we embark on this, we began to think about how to model the database around it. We have a couple of constraints within Avo's context, which makes it a bit more challenging.
#### 1. We don't own the records/models that sit on the board
This is the ethos of Avo; the user can have Users, Products, ToDos, and any other kind of models added to the board. We don't own those models and can't dictate the design decisions around them.
#### 2. We don't want to enforce database restrictions (or have as few as possible)
Another big feature of Avo is that you configure it with code and not by database rows. This is powerful because all your configuration is very portable across all environments. This means we don't ship any migrations with Avo and, again, don't impose database restrictions on you.
So how do we keep track of which item is on which board/column?
#### 3. We want multi-item-type boards
We'd love to support boards that handle multiple item types, meaning you could have a User, a Product, and a To-Do on the same board and work with all of them as if they were the same item.
#### 4. Make it as configurable as possible
We want this to be the ultimate Kanban board feature out there. Maybe not from the initial iteration, but still be able to easily add features as we progress.
### How Do We Do It?
It's an interesting challenge, I think.
#### Initial Iteration
We first thought about the simplest use case. We would require the user to add a column to each record type in the database to indicate which column that record is placed in.
That quickly becomes problematic if you want that record in multiple columns.
```ruby
User
- id
- name
- kanban_column # add this to hold the board it is on
```
This starts to look like [Single Table Inheritance](https://guides.rubyonrails.org/association_basics.html#single-table-inheritance-sti).
You also need to hold the position on the board. Adding another database column? What if you need to add another property? It starts getting messy really quickly.
#### Second Iteration
Then, we thought about holding the position and board information in a different table. This is great as it doesn't impact the user's database modeling. We can "do what we want there" and not bother the user.
```ruby
User
- id
- name
KanbanItem
- record_type ("User")
- record_id (55)
- column ("In progress") # which column
- position (2) # position in the column
```
This is already better. But what does it look like? That's right! It looks like [Delegated Types](https://guides.rubyonrails.org/association_basics.html#delegated-types).
Delegated Types are a great abstraction for holding common data for multiple types of models. They have great heuristics and are proven and tested.
It checks all the boxes:
- We don't need to apply any updates to the user's model database structure.
- We can have the same record sit on multiple boards.
- This future-proofs this feature so we can customize it as we want.
We still have a few things to look into and test out, but the "meat" of the feature is there!
How would you build this feature?

1,916,988 | Introduction to CSS Animation: Bringing Websites to Life | In the field of web development, a website’s aesthetic appeal is essential for engaging users and... | 0 | 2024-07-09T08:51:25 | https://dev.to/code_passion/introduction-to-css-animation-bringing-websites-to-life-5bn3 | html, css, webdev, tutorial | In the field of web development, a website’s aesthetic appeal is essential for engaging users and improving their experience. CSS animation is an effective tools for developer. CSS animation allows developers to breathe life into static web elements, resulting in visually appealing and dynamic user interfaces that capture and delight visitors.
**Understanding CSS Animation**
[CSS animation](https://skillivo.in/introduction-to-css-animation-1/) enables developers to animate HTML elements without requiring JavaScript or any other tools. Keyframes, transitions, and other CSS attributes allow developers to control many aspects of an element’s appearance and behaviour over time.
**Key Concepts**
**1. keyframes**
A keyframe in CSS defines the styles that an element should have at certain moments during an animation sequence. Consider establishing waypoints along a path that an element will follow as it animates. These waypoints, given as percentages ranging from 0% to 100%, specify how the element should appear at each stage of the animation. ([Read more](https://skillivo.in/introduction-to-css-animation-1/))
**Syntax and Usage**
To define keyframes in CSS, use the @keyframes rule followed by a name for the animation sequence. Within the @keyframes block, you specify the percentage values (or keywords like from and to), as well as the CSS attributes and values that should be applied at certain points.
Here’s a basic example
```
@keyframes slide-in {
from {
transform: translateX(-100%);
}
to {
transform: translateX(0);
}
}
```
In this example, the slide-in animation slides an element from left to right, starting from outside the viewport (-100% of its width) and ending at its original position (0%).
**Applying Keyframes**
Once you’ve set your keyframes, use CSS’s animation property to apply them to elements. This property lets you provide the animation’s name, duration, timing function, delay, and other characteristics.
```
.element {
animation: slide-in 1s ease-out;
}
```
The slide-in animation is assigned to the.element class, which lasts for one second and uses an easing function for smooth acceleration and deceleration..
Let’s see an example
This animation makes text shake horizontally.
output:
```
<!DOCTYPE html>
<html>
<head>
<meta charset='utf-8'>
<meta http-equiv='X-UA-Compatible' content='IE=edge'>
<title>Page Title</title>
<meta name='viewport' content='width=device-width, initial-scale=1'>
<style>
.shaker {
font-size: 24px;
animation: shake 0.5s cubic-bezier(0.36, 0.07, 0.19, 0.97) infinite;
}
div
{
width:500px;
margin: 0 auto;
margin-top:300px;
}
@keyframes shake {
0%, 100% { transform: translateX(0); }
25% { transform: translateX(-5px); }
50% { transform: translateX(5px); }
75% { transform: translateX(-3px); }
100% { transform: translateX(3px); }
}
</style>
</head>
<body>
<div class="shaker">Shaking Text</div>
</body>
</html>
```
These HTML examples show how to include CSS keyframe animations into your web pages and create engaging visual effects.
**Animation Properties of CSS Animation**
[CSS animation](https://skillivo.in/introduction-to-css-animation-1/) properties allow developers to precisely control how items move, transform, and transition on a web page. These features allow you to create appealing animations without using JavaScript or external libraries. ([click Here](https://skillivo.in/introduction-to-css-animation-1/) to read more examples of css animation)
Syntax:
```
animation: name duration timing-function delay iteration-count direction fill-mode play-state;
```
let’s look at another example
output:
```
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Cubic Bezier Bouncing Animation Example</title>
<style>
.ball {
width: 100px;
height: 100px;
background-color: #df6412;
border-radius: 50%;
position: absolute;
top: 50%;
left: 50%;
animation: bounce 1.5s cubic-bezier(0.68, -0.55, 0.265, 1.55) infinite;
}
@keyframes bounce {
0%, 100% {
transform: translateY(0);
}
50% {
transform: translateY(-100px);
}
}
</style>
</head>
<body>
<div class="ball"></div>
</body>
</html>
```
In this example
1. The animation property adds a bouncing effect to the ball element by using keyframe animations.
2. The cubic Bézier timing function used in the animation is defined by the cubic-bezier(0.68, -0.55, 0.265, 1.55) function, with specific control points.
3. The bounce keyframes animation create the bounce effect, starting from the initial state (0%) to halfway (50%) where the ball is translated upward by 100px (translateY(-100px)) and then returning to the initial state (100%).
4. By adjusting the control points of the cubic Bézier curve, you may customise the timing and behaviour of the bouncing animation to produce desired results.
**Conclusion**
CSS animation features give developers a variety of tools to create visually beautiful and interactive web experiences. By mastering these features and integrating them in new ways, developers can bring their designs to life and increase user engagement. CSS animations are best learned through experimentation and practice. ([Read more about CSS Animation](https://skillivo.in/introduction-to-css-animation-1/)) | code_passion |

1,917,017 | What's the Difference Between Session-Based Authentication and JWTs? | Introduction In the world of web development, authentication is a crucial aspect that... | 0 | 2024-07-09T09:18:43 | https://dev.to/ruzny_ma/whats-the-difference-between-session-based-authentication-and-jwts-49gg | webdev, jwt, security, node | ## **Introduction**
In the world of web development, authentication is a crucial aspect that ensures secure communication between the client and the server. Two common methods of authentication are session-based authentication and JWT (JSON Web Token) token-based authentication. While both methods serve the same purpose, they have different mechanisms and use cases. In this blog post, we'll explore the differences between these two authentication methods, their advantages, and their potential drawbacks.
## Session-Based Authentication
Session-based authentication is a traditional method where the server maintains the authentication state. Here's how it typically works:
1. **User Login:** The user provides their credentials (username and password) to log in.
2. **Server Verification:** The server verifies the credentials. If they are correct, the server creates a session.
3. **Session ID Creation:** The server generates a unique session ID and stores it in a session store (usually an in-memory store like Redis or a database).
4. **Cookie Storage:** The session ID is sent back to the client in a cookie.
5. **Subsequent Requests:** For every subsequent request, the client sends the cookie with the session ID.
6. **Server Validation:** The server checks the session store for the session ID to validate the user's identity.
### Advantages of Session-Based Authentication
- **Security:** Since the session ID is stored on the server, it can be invalidated easily by the server if necessary.
- **Simplicity:** Easy to implement and widely understood.
### Drawbacks of Session-Based Authentication
- **Scalability:** As the user base grows, maintaining sessions in a centralized store can become a bottleneck.
- **Stateful:** The server needs to maintain the state, which can complicate server-side logic and load balancing.
## JWT-Based Authentication
JWT-based authentication is a more modern approach that eliminates the need for server-side session storage. Here's how it works:
1. **User Login:** The user provides their credentials to log in.
2. **Server Verification:** The server verifies the credentials. If they are correct, the server generates a JWT.
3. **Token Creation:** The JWT contains the user's information and is signed using a secret key or a public/private key pair.
4. **Token Storage:** The JWT is sent back to the client, usually stored in local storage or a cookie.
5. **Subsequent Requests:** For every subsequent request, the client sends the JWT.
6. **Server Validation:** The server verifies the JWT's signature and extracts the user's information.
### Advantages of JWT-Based Authentication
- **Scalability:** No need for server-side session storage, making it easier to scale horizontally.
- **Stateless:** The server doesn't need to maintain the state, simplifying the architecture.
- **Self-Contained:** All necessary information is stored within the token, reducing server load.
### Drawbacks of JWT-Based Authentication
- **Invalidation:** Invalidating a JWT before its expiration time can be challenging.
- **Stale Data:** The data within the JWT can become stale if the user's information changes.
- **Token Size:** JWTs can be large, increasing the payload size for each request.
## Choosing the Right Method
Ultimately, the choice between session-based authentication and JWT-based authentication depends on the specific needs of your application. Here are some considerations:
### Session-Based Authentication
- Suitable for applications with a smaller user base.
- Preferred when you need to easily invalidate sessions.
- Better for environments where security is a top priority.
### JWT-Based Authentication
- Ideal for large-scale applications with distributed systems.
- Useful when you want a stateless architecture.
- Efficient for microservices and APIs that require scalability.
## **Conclusion**
Both session-based authentication and JWT-based authentication have their pros and cons. Understanding their differences and use cases will help you make an informed decision based on your application's requirements. By mastering these concepts, you'll be well-prepared to implement secure and efficient authentication mechanisms in your projects.

1,917,158 | Database Normalization simplified | Applying the normalization rules You can apply the data normalization rules (sometimes just called... | 0 | 2024-07-09T10:45:09 | https://dev.to/muhammad_salem/database-normalization-simplified-1lm8 | Applying the normalization rules
You can apply the data normalization rules (sometimes just called normalization rules) as the next step in your design. You use these rules to see if your tables are structured correctly. The process of applying the rules to your database design is called normalizing the database, or just normalization.
Normalization is most useful after you have represented all of the information items and have arrived at a preliminary design. The idea is to help you ensure that you have divided your information items into the appropriate tables. What normalization cannot do is ensure that you have all the correct data items to begin with.
You apply the rules in succession, at each step ensuring that your design arrives at one of what is known as the "normal forms." Five normal forms are widely accepted — the first normal form through the fifth normal form. This article expands on the first three, because they are all that is required for the majority of database designs.
Sure! Let's walk through the normalization process step by step, up to the third normal form (3NF), using clear examples to illustrate each step.
### First Normal Form (1NF)
**Definition**: A table is in the first normal form if:
1. All the columns contain atomic (indivisible) values.
2. Each column contains values of a single type.
3. Each column contains a unique name.
4. The order in which data is stored does not matter.
**Example:**
Consider a table for storing customer orders:
| OrderID | CustomerName | CustomerPhone | Product1 | Product2 | Product3 | ... |
|---------|--------------|---------------|----------|----------|----------|-----|
| 1 | John Doe | 123-456-7890 | Widget A | Widget B | NULL | ... |
| 2 | Jane Smith | 987-654-3210 | Widget C | NULL | NULL | ... |
This table is not in 1NF because it has repeating groups (Product1, Product2, Product3, ...).
To convert this to 1NF, we should remove the repeating groups and ensure each column contains only atomic values:
| OrderID | CustomerName | CustomerPhone | Product |
|---------|--------------|---------------|----------|
| 1 | John Doe | 123-456-7890 | Widget A |
| 1 | John Doe | 123-456-7890 | Widget B |
| 2 | Jane Smith | 987-654-3210 | Widget C |
Now, each column contains atomic values and there are no repeating groups.
### Second Normal Form (2NF)
**Definition**: A table is in the second normal form if:
1. It is in 1NF.
2. All non-key attributes are fully functional dependent on the primary key (i.e., there are no partial dependencies).
**Example:**
Consider the 1NF table from above:
| OrderID | CustomerName | CustomerPhone | Product |
|---------|--------------|---------------|----------|
| 1 | John Doe | 123-456-7890 | Widget A |
| 1 | John Doe | 123-456-7890 | Widget B |
| 2 | Jane Smith | 987-654-3210 | Widget C |
Here, `CustomerName` and `CustomerPhone` are partially dependent on `OrderID` since they depend on the customer, not the specific product in the order.
To achieve 2NF, we separate the table into two tables: one for orders and another for customers:
**Orders Table:**
| OrderID | CustomerID | Product |
|---------|------------|----------|
| 1 | 1 | Widget A |
| 1 | 1 | Widget B |
| 2 | 2 | Widget C |
**Customers Table:**
| CustomerID | CustomerName | CustomerPhone |
|------------|--------------|---------------|
| 1 | John Doe | 123-456-7890 |
| 2 | Jane Smith | 987-654-3210 |
Now, all non-key attributes are fully dependent on the primary key of each table.
### Third Normal Form (3NF)
**Definition**: A table is in the third normal form if:
1. It is in 2NF.
2. There are no transitive dependencies (i.e., non-key attributes do not depend on other non-key attributes).
**Example:**
Consider our 2NF tables:
**Orders Table:**
| OrderID | CustomerID | Product |
|---------|------------|----------|
| 1 | 1 | Widget A |
| 1 | 1 | Widget B |
| 2 | 2 | Widget C |
**Customers Table:**
| CustomerID | CustomerName | CustomerPhone |
|------------|--------------|---------------|
| 1 | John Doe | 123-456-7890 |
| 2 | Jane Smith | 987-654-3210 |
Assume we have another table for products with product details:
**Products Table:**
| ProductID | ProductName | Price |
|-----------|-------------|-------|
| A | Widget A | 10.00 |
| B | Widget B | 15.00 |
| C | Widget C | 20.00 |
To achieve 3NF, ensure there are no transitive dependencies. In our case, there are none since `ProductName` and `Price` are attributes of the Products table and are not dependent on any other non-key attribute.
The final structure is:
**Orders Table:**
| OrderID | CustomerID | ProductID |
|---------|------------|-----------|
| 1 | 1 | A |
| 1 | 1 | B |
| 2 | 2 | C |
**Customers Table:**
| CustomerID | CustomerName | CustomerPhone |
|------------|--------------|---------------|
| 1 | John Doe | 123-456-7890 |
| 2 | Jane Smith | 987-654-3210 |
**Products Table:**
| ProductID | ProductName | Price |
|-----------|-------------|-------|
| A | Widget A | 10.00 |
| B | Widget B | 15.00 |
| C | Widget C | 20.00 |
### Summary
1. **1NF**: Ensure each table column contains atomic values and there are no repeating groups.
2. **2NF**: Ensure the table is in 1NF and all non-key attributes are fully dependent on the primary key.
3. **3NF**: Ensure the table is in 2NF and there are no transitive dependencies.
By following these steps, you can normalize your database to ensure it is well-structured and efficient, reducing redundancy and ensuring data integrity. | muhammad_salem | |
1,917,057 | Mastering API Versioning: Strategies for Seamless Frontend-Backend Communication in Mobile Apps | Effective API versioning is essential for maintaining seamless communication between the frontend and... | 0 | 2024-07-09T09:21:06 | https://dev.to/theodo/mastering-api-versioning-strategies-for-seamless-frontend-backend-communication-in-mobile-apps-12o7 | api |
Effective API versioning is essential for maintaining seamless communication between the frontend and backend. This article explains why API versioning is important and analyses various versioning strategies, offering practical insights for backend and mobile app developers. My goal is to equip you with the knowledge to manage API versions efficiently, by ensuring a practical experience for developers while maintaining a seamless user experience. This article is based on our experience with API versioning in the [PassCulture](https://pass.culture.fr/) app.
# 1. Context
In the PassCulture app, as with many applications, we control both the frontend and the backend. However, we do not control the version of the frontend that the user is using. This lack of control over the app version necessitates effective API versioning to ensure compatibility and functionality across different user versions. As the app evolves, the API code may change to accommodate new versions of the app, which may not be compatible with older versions.
For example, consider an API endpoint for user authentication that initially requires a username and password.
```python
@app.route('/auth', methods=['POST'])
def auth():
username = request.json['username']
password = request.json['password']
user = User.query.filter_by(username=username).first()
if user and user.check_password(password):
return jsonify({'token': generate_token()}), 200
return jsonify({'error': 'Invalid credentials'}), 401
```
The frontend (app V1) would send a request to this endpoint with the following code:
```javascript
fetch("/auth", {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({
username: "user",
password: "password",
}),
});
```
Now, suppose we want to add two-factor authentication to the app. We could modify the endpoint to require an additional field, `otp`, for the one-time password.
```python
@app.route('/auth', methods=['POST'])
def auth():
username = request.json['username']
password = request.json['password']
otp = request.json['otp']
user = User.query.filter_by(username=username).first()
if user and user.check_password(password) and user.check_otp(otp):
return jsonify({'token': generate_token()}), 200
return jsonify({'error': 'Invalid credentials'}), 401
```
The frontend (app V2) would need to be updated to include the `otp` field in the request.
```javascript
fetch("/auth", {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({
username: "user",
password: "password",
otp: "123456",
}),
});
```
However, app V1 would not include the otp field, resulting in an error when users on V1 try to authenticate. To avoid this issue, we need to implement API versioning. This way, both versions of the app can interact with the backend appropriately: app V1 can continue to use the original endpoint without otp, while app V2 can use a new version of the endpoint that requires otp. This ensures compatibility and a seamless user experience across different app versions.
# 2. Alternatives to API Versioning
Is API versioning the only solution to manage changes in the backend code? Not necessarily. Here are some alternatives to API versioning:
## a. Forced App Updates
One way to manage changes in the backend code is to force users to update their app. This approach ensures that all users are on the latest version of the app, which is compatible with the latest backend code. However, forced app updates can be disruptive to users and may not always be feasible, especially if users are on older devices or have limited internet connectivity.
Forced updates are a good solution for critical issues, such as security vulnerabilities, that require immediate action.However, they may not be the best approach for non-critical changes or new features.
## b. Feature Flags
Feature flags allow you to control the visibility of new features in the app without requiring a new version. By using feature flags, you can gradually roll out new features to users without forcing them to update the app. However, feature flags can be complex to manage and may not be suitable for all types of changes.
If we take the previous example of adding two-factor authentication, we can write the V2 code as follows:
```javascript
if (featureFlags.twoFactorAuth) {
fetch("/auth", {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({
username: "user",
password: "password",
otp: "123456",
}),
});
} else {
fetch("/auth", {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({
username: "user",
password: "password",
}),
});
}
```
Then we would enable the feature flag when all users have updated their app to V2 and we will simultaniously update the backend code to handle the new field.
We will then need to clean the code to remove the old code and the feature flag.
This approach can be useful for simultaneously rolling out new features across different app versions. However, it requires careful management of feature flags and may introduce complexity to the codebase.
## c. API Route Backward Compatibility
Another approach is to maintain backward compatibility in the API routes. This means that the backend code is designed to handle requests from older app versions, even if the route has been updated. For example, the backend code can check if the request contains the `otp` field and handle it accordingly.
Example:
```python
@app.route('/auth', methods=['POST'])
def auth():
username = request.json['username']
password = request.json['password']
otp = request.json.get('otp') # Use get to avoid KeyError
user = User.query.filter_by(username=username).first()
if user and user.check_password(password) and (otp is None or user.check_otp(otp)):
token = generate_token()
if opt is None:
limit_access_to_some_features(token)
return jsonify({'token': token}),200
return jsonify({'error': 'Invalid credentials'}), 401
```
This approach can be useful for minor changes. However, it can lead to complex code and potential bugs if not managed properly. It also requires careful testing to ensure that backward compatibility is maintained. It also requires the developer to clean the code once the old version of the app is no longer used.
# 3. **Possible Versioning Solutions**
When managing multiple API versions, there are several strategies to consider. Mainly three strategies come to mind:
## a. **Code level versioning**
This solution consists of managing the different versions of the routes in the code.
In this case, the different route versions are just different routes in the code. We declare new routes with the version included in the URL.
Example:
```python
@app.route('/v1/auth', methods=['POST'])
@route.deprecated
def auth():
pass
@app.route('/v2/auth', methods=['POST'])
def auth_v2():
pass
```
In this case, The app specifies the version of the route it wants to use in the URL.
For example the app V1 will use the route `/v1/auth` as follows:
```javascript
fetch("/v1/auth", {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({
username: "user",
password: "password",
}),
});
```
The app V2 will use the route `/v2/auth` as follows:
```javascript
fetch("/v2/auth", {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({
username: "user",
password: "password",
otp: "123456",
}),
});
```
## b. **Infrastructure level versioning**
This solution consists of deploying multiple API instances in parallel on different pods. Each instance corresponds to a version of the API. The app specifies the version of the API it wants to use in the request. The infrastructure is responsible for routing the request to the correct API instance.
A Pod is a group of one or more containers, with shared storage/network resources, and a specification for how to run the containers. Pods are the smallest deployable units of computing that can be created and managed in Kubernetes. Read more about [Kubernetes Pods](https://kubernetes.io/docs/concepts/workloads/pods/).
In this case, whenever the developer wants to create a new version of a route, he just needs to change the code without thinking about the old version. The old version of the route will still be available as long as the old pod is still running, and the new version will be available as soon as a new pod is deployed with the latest API code.
When a pod is no longer used, it can be deleted. This will delete the old version of the route. Deleting the pod will depend on the oldest version of the app users can still use.
In general, a git branch is created for each version of the API. In case of critical issues, modifying the old code can be done by cherry-picking the fix commit to the versions branch and redeploying it from that branch.
In contrast, to code level versioning, infrastructure level versioning doesn't require the developer to clean the code when the old version is no longer used. Additionaly, infrastructure level versioning ensures that a change in the code will not affect the old versions of the app, thus requiring no quality check on the old versions of the app.
## c. **Backend For Frontend (BFF) level versioning**
This type of versioning is a compromise between the two previous solutions. It consists of splitting the backend into two parts: the main backend and the BFF. The main backend is responsible for the business logic and the data access. The BFF is responsible for calling the main backend and formatting the data in the way that each app version expects. The BFF is versioned, and the app specifies the version of the BFF it wants to use in the request.
The main contrast between this solution and the infrastructure level versioning is that it ensures that a change in the business logic will affect all versions of the app. While keeping the advantage of the infrastructure level versioning of not needing to clean the code.
However it requires a good separation of the business logic from the data formatting and the data access.
# 4. **Key Considerations**
In order to choose the best solution for API versioning, we consider the following key criteria:
## a. **Correcting Critical Bugs Across Versions**
It’s crucial to be able to check which versions are affected by a bug or a vunerability. It’s also important to be able to fix the bug in all affected versions.
## b. **Same business logic for all versions**
It’s important to ensure that a change in the business logic will affect all versions of the app. Since this can create inconsistances between the different versions of the app. And a use of an old business logic can be a critical security issue.
## c. **Maniability**
It should be easy for the developers to manage the multiple versions:
- Easy to create, update or delete a version of a route
- Easy to mark versions as deprecated
- Easy to update the app's code to use a new version of a route
## d. **No Version inter-dependency**
When managing multiple versions, it's important to be able to make changes to a specific version without affecting others. For example, if there is a bug in version 1.0.0, you should be able to fix it without impacting version 2.0.0. Releasing a new version should not affect existing versions, thereby avoiding the risk of introducing new bugs into old versions. This approach ensures that older versions remain stable and reliable, eliminating the need for unnecessary quality checks on all versions with every release. This strategy should allow for better control over the quality of older versions.
## e. **Traceability**
It should be easy to know which version of a route is being used by which version of the app and vice versa.
This allows for better tracking of the usage of the different versions of the routes, helping on decisions for when to delete or update existing routes.
## f. **Deployment process**
The chosen solution should make the deployment process simple. It should be easy to deploy a new version of a route.
## g. **Set Up**
The effort required to set up the solution should be taken into account. The solution should be easy to set up and maintain.
# 5. **Evaluation of the different solutions**

# 6. Our choice
After evaluating the different versioning strategies, we opted for code-level versioning. Here’s why:
Complexity: We ruled out infrastructure-level versioning due to its complexity in setup and maintenance. Additionally, it was crucial for us that any change in business logic affects all app versions, which infrastructure-level versioning does not guarantee.
Independence: While BFF level versioning provides some degree of version independence, it also introduces significant setup and maintenance challenges. Furthermore, it doesn’t ensure full version independence.
Business Logic Separation: By effectively separating the business logic from data formatting and access, code-level versioning can offer the same benefits as BFF level versioning. In our scenario, complete independence between versions is not critical, thanks to our comprehensive test suite that catches most bugs introduced by changes. Additionally, we are working towards automating end-to-end tests to identify critical bugs in older app versions.
Practicality: Given our context, simplicity is key. Code-level versioning emerged as the most straightforward and practical solution, aligning well with our testing strategies and maintenance capabilities.
Therefore, we settled on code-level versioning as it meets our needs without adding unnecessary complexity.
# Conclusion
I have explained the importance of API versioning and presented three solutions—infrastructure-level, BFF-level, and code-level versioning—each with its own pros and cons.
If you are managing an application where backend and frontend evolve independently, versioning is crucial. I suggest starting by determining your priorities and assessing the most important criteria, and I hope this article will help you to select the best versioning strategy for your needs.

_Windows-Security_
- Now, click on **Virus & Threat Protection** which is available under Protection areas.
_Virus-Threat-Protection_
- Windows Security will open now. Click on **Firewall & Network Protection**.
_Firewall and Network Protection_
- Click on **Allow an app through firewall**.
_Allow an App through Windows Firewall_
- Windows Firewall Allowed Apps will open now. Click on **Change Settings** so that the system will allow you to make changes to the Allowed Apps. You might be prompted to enter an **Administrator password** or confirm your choice.
_Change Settings_
- Scroll through the list of apps available, and locate the app that you want to allow through Windows Firewall.
- Once you find your app, you can find two check boxes next to it, **Private and Public**. Private networks are networks that you trust, such as your home or office network. Public networks are networks that you do not trust or not familiar with, such as a public Wi-Fi at a mall or airport. Choose accordingly.
- Finally, click **OK** to save the changes. Your selected app should now be allowed through Windows Firewall in Windows 11.
Note: You can also use Start menu and Control Panel to access Windows Security in Windows 11.
## What are the Risks of allowing an app through Windows Firewall?
**Allowing an app through Windows Firewall** introduces several risks, such as **unauthorized access** and **data leakage**. If the app has security vulnerabilities or becomes compromised, attackers can exploit these weaknesses to gain unauthorized access to your system, potentially leading to **data breaches**. Additionally, allowing apps increases your network’s attack surface, providing more opportunities for malware to communicate with **command-and-control servers** , which can further spread infections or exfiltrate data. Furthermore, allowing unnecessary apps can consume **network bandwidth and system resources** , affecting overall performance.
### When should an App be allowed?
_Safe Computing with Windows Firewall_
There are three crucial considerations. **Trusted Source, Specific need, and Proper Configuration**.
1. Ensure the app comes from a trusted source and is not malicious. Only allow apps that are necessary and verified to be safe.
2. Allow the app through the firewall only if it specifically needs network access to function. Unnecessary allowances can create security risks.
3. Configure the firewall to allow only the necessary types of traffic for the app. For example, allow specific ports, protocols, or IP addresses rather than a broad allowance.
> #### Information on the Go!
>
> The principle of “ **default deny** ” is a security best practice. It means that by default, all connections are blocked, and only those explicitly allowed are permitted. This minimizes the attack surface and enhances security.
## Restore Firewalls to default in Windows 11:
If you wish to restore the Firewall Settings back to its default configuration, follow the below steps.
- Under **Firewall and Network Protection** , click on **Restore firewalls to default**.
_Restore Firewall Settings_
- Now, Default Settings window will open now. Click on **Restore Defaults**.
_Restore Defaults_
- This option will remove Windows Defender Firewall settings that you have configured for all network locations. Please note that this might cause some apps to stop working.
## Take away:
Windows Firewall blocks apps **by default** , even those from trusted sources, to maintain a high level of security and ensure that only necessary network communications are allowed. This approach helps maintain a secure computing environment and minimizes the risk of unauthorized access and data breaches. By being cautious and selective about which apps are allowed through Windows Firewall, you can minimize potential security risks and maintain a more secure network environment in Windows 11. **Safe Computing!

Whether you're manipulating the DOM, handling events, or working with AJAX, mastering these shortcuts can greatly enhance your productivity. Here are 15 handy jQuery tips to optimize your code:
## 1. Chaining Methods
Take advantage of method chaining to perform multiple actions on the same set of elements in a single line of code.
```
$('div').addClass('highlight').slideDown().fadeIn();
```
## 2. Shorthand for Document Ready
Use the short version of `$(document).ready()` to run code when the DOM is fully loaded.
```
$(function() {
// Code to run when the DOM is ready
});
```
## 3. Event Delegation with on
Delegate events using `on` to handle events for dynamically added elements efficiently.
```
$(document).on('click', '.dynamic-element', function() {
// Event handling code
});
```
## 4. Element Existence Check
Check if an element exists before performing actions to prevent errors.
```
if ($('#element').length) {
// Element exists, perform actions
}
```
## 5. Selecting Multiple Elements
Select multiple elements at once by separating them with commas.
```
$('p, .class, #id').hide();
```
## 6. Efficient Attribute Manipulation
Use prop instead of `attr` for properties like `checked`, `disabled`, and `selected` for better performance.
```
$('#checkbox').prop('checked', true);
```
## 7. Using `$.each` for Iteration
Iterate over arrays and objects efficiently with `$.each`.
```
$.each(array, function(index, value) {
console.log(index + ": " + value);
});
```
## 8. Data Storage with `.data()`
Store and retrieve custom data associated with elements using `.data()`.
```
$('#element').data('key', 'value');
console.log($('#element').data('key'));
```
## 9. Shorthand for AJAX
Use shorthand methods like `$.get`, `$.post`, and `$.getJSON` for AJAX requests.
```
$.get('url', function(data) {
console.log(data);
});
```
## 10. Use `$.trim` to Clean Strings
Remove leading and trailing whitespace from strings with `$.trim`.
```
var cleanString = $.trim(' some text ');
console.log(cleanString); // "some text"
```
## 11. `toggleClass` for Toggle Behavior
Toggle classes on elements using `toggleClass` for easy add/remove functionality.
```
$('#element').toggleClass('active');
```
## 12. Filtering Elements
Refine selections using filters like `:first`, `:last`, `:even`, `:odd`, etc., to target specific elements efficiently.
```
$('li:first').addClass('first-item');
```
## 13. `slideUp` and `slideDown`
Animate element visibility with `slideUp` and `slideDown` for smooth transitions.
```
$('#element').slideUp();
```
## 14. Handling Forms with `serialize`
Serialize form data into a query string for AJAX submissions.
```
var formData = $('#myForm').serialize();
$.post('submit.php', formData, function(response) {
console.log('Response: ' + response);
});
```
## 15. `empty` and `remove`
Use `empty` to remove child elements and content within an element, and `remove` to completely remove elements from the DOM.
```
$('#container').empty();
$('#element').remove();
```
## Conclusion
These jQuery shortcut tips empower you to write cleaner, more efficient JavaScript code. By integrating these techniques into your workflow, you'll enhance productivity and maintainability in your web development projects.

1,917,081 | Android Launch Modes | Launch modes of android tell us how our activity instances will be maintained in activity history... | 0 | 2024-07-09T09:28:17 | https://dev.to/dilip_chandar_58fce2b3b7b/android-launch-modes-2pjh | android, androiddev | Launch modes of android tell us how our activity instances will be maintained in activity history stack.
There are 4 types of launch modes
**standard**
**singleTop**
**singleTask**
**singleInstance**
**1. standard**
This is the default launch mode of activity in android. We don’t have to explicitly specify this in AndroidManifest.xml. When an activity is of this launch mode type, it will have multiple instances.
For example if Activity A, which is of standard launch mode type, whenever this activity is launched, it will create new instance of Activity A.
**2. singleTop**
This is the next type of launch mode which can also have multiple instances of the activity similar to standard type but on certain conditions. We have to specify that for the required activity in AndroidManifest.xml like this
**android:launchMode="singleTop"**
Whenever an activity falls into this type, on launch of this particular activity, new instance of the activity will only be created if it is not on the top of the recent activity history stack. Otherwise existing instance which is present on top will be re-used.
_Activity A(singleTop) -> Activity B(standard) -> Activity A(singleTop)_
In the above flow, Activity A is launched at first. Then Activity B is launched. Again Activity is launched. But as activity A is not in top and Activity B is in top, new instance of Activity A is created.
In the same flow, if activity A is again launched, it will re-use existing instance since it was already present on top
_Activity A(singleTop) -> Activity B(standard) -> Activity A(singleTop)_
**3. singleTask**
This type of launch mode can only have one instance of the activity and should be specified in AndroidManifest.xml like this
**android:launchMode=”singleTask”**
Whenever an activity falls into this type of launch mode, on launch of the particular activity, it will create new instance only once. And when launched again, it will re-use the existing instance regardless of whether it is in top or other order of history stack. And while re-using the instance, it will clear stack of all activities below it and then get launched.
For example:
_Activity A (standard) -> Activity B (singleTop) -> Activity C (singleTask)_
Now if activity C is launched, it will clear history of activity A and activity B and Activity C will be the only activity left in history stack.
**4. singIeInstance**
This type of launch mode can also have only one instance of the particular activity. We have to specify this launch mode in AndroidManifest.xml like this
**android:launchMode=”singleInstance”**
This type of launch mode is useful to separate the activity from existing stack and create the instance in a separate task. And in that task also, only one instance of the activity can exist.
For example:
_Activity A (standard) -> Activity B (singleTop) -> Activity C (singleTask)_
Now if Activity D (singleInstance) is launched, the flow will be like below
**Task or Stack 1:** _Activity A (standard) -> Activity B (singleTop) -> Activity C (singleTask)_
**Task or Stack 2:** _Activity D (singleInstance)_
As you can see, both are in separate history stack.
Note: Whenever an existing instance has to be re-used in any one of the launch modes like singleTop, singleTask and singleInstance, a method called **onNewIntent(Intent intent)** will be triggered.
Happy coding..

The global [footwear market](https://www.persistencemarketresearch.com/market-research/footwear-market.asp) is projected to reach approximately US$592 billion by 2032, growing steadily at a compound annual growth rate (CAGR) of 4.2% from 2024 to 2032. Key highlights include the rising popularity of smart footwear with integrated technology for activity tracking and personalized coaching. Direct-to-consumer (D2C) models are gaining traction as brands aim to connect directly with consumers, enhancing market growth. The growth of e-commerce is also pivotal in expanding market reach.
Footwear encompasses a wide range of products, from fashion-forward shoes to sports and casual footwear. Consumer preferences drive demand across various categories, including safety and industrial footwear used in sectors like construction and mining. Materials such as rubber, textiles, synthetics, foam, leather, and recycled plastics are utilized in production, balancing cost effectiveness with durability and functionality.
The market benefits from increased disposable income and growing awareness of the health benefits associated with sports and fitness activities. Demand for athletic footwear is particularly influenced by rising health concerns due to sedentary lifestyles, alongside global sporting events like the Olympics and World Cup, which spur interest in sports-related footwear among lifestyle consumers.
As the athletic footwear industry continues to expand, driven by a combination of technological advancements, shifting consumer preferences, and emerging market dynamics, understanding the market share dynamics becomes crucial for stakeholders. This press release delves into the current market share landscape, highlighting key trends and innovations that are shaping the future of the industry.
**1. Market Share Landscape**
The athletic footwear market has seen robust growth over the past few years, with key players such as Nike, Adidas, Puma, Under Armour, and ASICS leading the charge. According to recent reports, Nike holds the largest market share, followed closely by Adidas. These two giants dominate the global market, together accounting for a significant portion of sales. However, smaller and emerging brands are also making their mark, particularly in niche segments and regional markets.
Nike’s market leadership is attributed to its strong brand recognition, innovative products, and extensive global reach. The company’s strategic investments in technology, such as smart and connected footwear, as well as its emphasis on sustainability, have further solidified its position. Adidas, on the other hand, has excelled through its focus on performance, style, and sustainability initiatives, including its popular Boost technology and Parley ocean plastic collaboration.
**2. Technological Innovations: Smart Footwear and Performance Enhancement**
Technological integration remains a driving force in the athletic footwear market. Brands are leveraging advanced technologies to enhance performance, comfort, and user experience. Smart footwear, equipped with sensors and connectivity features, is gaining traction among athletes and fitness enthusiasts.
Nike and Under Armour have been pioneers in this space. Nike’s Adapt series, featuring self-lacing technology and app-controlled fit adjustments, represents a significant leap in footwear innovation. Under Armour’s HOVR series includes embedded sensors that track performance metrics and provide real-time feedback, helping athletes optimize their training routines.
Performance enhancement technologies are also crucial. ASICS, renowned for its focus on biomechanics, continues to innovate with features like GEL cushioning and FlyteFoam midsoles that offer superior shock absorption and energy return. Brooks, another performance-focused brand, has gained a loyal following with its DNA LOFT cushioning and GuideRails support system, designed to enhance stability and reduce the risk of injuries.
**3. Sustainability: The Green Revolution in Athletic Footwear**
Sustainability has become a central theme in the athletic footwear market, driven by increasing environmental awareness among consumers. Brands are adopting eco-friendly materials and sustainable manufacturing processes to reduce their environmental footprint.
Adidas has made significant strides with its Futurecraft Loop, a fully recyclable shoe designed to be remade into new shoes at the end of its lifecycle. The company’s collaboration with Parley for the Oceans to create shoes from recycled ocean plastic has also garnered positive attention. Nike’s Move to Zero initiative focuses on reducing waste and carbon emissions across its product lines, with products like the Space Hippie collection made from recycled materials.
Smaller brands like Allbirds and Veja are also making a significant impact with their commitment to sustainability. Allbirds uses materials like merino wool, eucalyptus tree fiber, and sugarcane to create comfortable and eco-friendly shoes, while Veja’s emphasis on organic cotton, wild rubber, and fair trade practices has resonated with environmentally conscious consumers.
**4. Customization and Personalization: Meeting Diverse Consumer Preferences**
Customization and personalization have become crucial in catering to the diverse preferences of today’s consumers. Advances in digital technology, particularly 3D printing, are enabling brands to offer bespoke footwear solutions.
Nike’s By You platform and Adidas’ miAdidas service allow consumers to personalize their shoes, choosing from various materials, colors, and performance features. This trend is not only enhancing customer satisfaction but also fostering deeper brand loyalty as consumers seek products that reflect their unique identities and performance needs.
Under Armour has also embraced this trend with its ICON customization platform, allowing athletes to create personalized designs for their footwear. This focus on customization is particularly appealing to younger consumers who value individuality and self-expression.
**5. Athleisure and Versatility: Blurring the Lines Between Athletic and Casual Wear**
The athleisure trend, blending athletic and casual wear, continues to dominate the market. Consumers prioritize comfort and versatility, driving demand for athletic shoes that can transition seamlessly from the gym to everyday activities.
Brands are responding with innovative designs that offer both performance and style. New Balance, for example, has expanded its athleisure offerings with designs that appeal to a broad demographic. The company’s focus on comfort and performance has resonated with consumers seeking versatile footwear for various activities.
Similarly, Adidas’ Yeezy line, a collaboration with Kanye West, combines high-fashion aesthetics with the comfort of athletic shoes, catering to fashion-conscious consumers. This trend underscores the growing importance of versatility in footwear design, as consumers seek products that meet their diverse lifestyle needs.
**6. Direct-to-Consumer (DTC) Models: Revolutionizing Retail**
The shift towards direct-to-consumer (DTC) models is reshaping the athletic footwear retail landscape. By bypassing traditional retail channels, brands can offer more competitive pricing, greater product variety, and enhanced customer experiences.
Allbirds and Hoka One One are prime examples of brands successfully leveraging the DTC model. Allbirds, which began as an online-only brand, has expanded its presence with physical stores while maintaining a strong online sales strategy. Hoka One One, known for its maximalist running shoes, has built a loyal customer base through its online platform, offering a seamless shopping experience and superior customer service.
This model also allows for more direct engagement with consumers, fostering stronger relationships and better understanding of customer preferences. As a result, brands can tailor their offerings to meet the evolving needs of their target audiences more effectively.
**7. The Role of Social Media and Influencer Marketing**
Social media and influencer marketing continue to play a pivotal role in shaping consumer perceptions and driving sales in the athletic footwear market. Platforms like Instagram, TikTok, and YouTube provide brands with powerful tools to reach and engage with a global audience.
Influencers, with their vast followings and authentic connections with their audiences, are instrumental in promoting new products and trends. Brands are increasingly collaborating with influencers to create buzz and drive consumer interest.
Puma’s partnerships with celebrities like Rihanna and Selena Gomez have significantly boosted its brand visibility and appeal among younger consumers. Similarly, Nike’s collaborations with athletes and social media personalities help maintain its status as a leading trendsetter in the market.
**8. Global Expansion and Emerging Markets**
The global expansion of athletic footwear brands into emerging markets presents significant growth opportunities. Rapid urbanization, rising disposable incomes, and increasing health consciousness in regions such as Asia-Pacific, Latin America, and Africa are driving demand for athletic footwear.
China and India, in particular, represent substantial growth opportunities for the athletic footwear market. Brands like Nike, Adidas, and Under Armour are investing heavily in these markets, establishing local manufacturing facilities, and launching targeted marketing campaigns to cater to the preferences of these diverse consumer bases.
**Conclusion**
The athletic footwear market is at a dynamic juncture, driven by a confluence of sustainability, technology, customization, and evolving consumer preferences. Brands that can adeptly navigate these trends and continue to innovate will not only capture market share but also shape the future of the industry.
As we move forward, the ability to balance performance with sustainability, style with comfort, and personalization with mass appeal will define the leaders in the athletic footwear market. The future of athletic footwear promises to be dynamic and diverse, reflecting the needs and aspirations of athletes and consumers worldwide. The industry's continued growth and innovation will undoubtedly provide exciting opportunities for brands and consumers alike.

1,917,085 | MIMI's Strong Strategies in a Volatile Market: Ensuring User Returns | Amid global financial turbulence, investors face unprecedented challenges and uncertainties. Recent... | 0 | 2024-07-09T09:31:31 | https://dev.to/mimi_official/mimis-strong-strategies-in-a-volatile-market-ensuring-user-returns-2f77 | Amid global financial turbulence, investors face unprecedented challenges and uncertainties. Recent significant events have profoundly impacted both traditional financial markets and the emerging cryptocurrency market, influencing market confidence and investment behaviour. In this context, providing stable investment options and guaranteeing returns has become essential for every financial platform.
As an innovative decentralized financial protocol, MIMI is dedicated to offering reliable investment tools and stable return guarantees in this volatile market environment. By leveraging advanced technology and stringent risk management, MIMI focuses on asset growth and protecting user interests during market fluctuations. Our goal is to ensure that users can invest with confidence under any market conditions and enjoy safe, transparent, and efficient financial services.
Global Market Dynamics and Cryptocurrency Challenges
The global market is experiencing significant events that are affecting traditional financial markets and bringing immense volatility and uncertainty to the cryptocurrency market. President Biden's announcement of his re-election campaign introduces future policy uncertainties, impacting market expectations. Concurrently, U.K. Prime Minister Sunak's resignation has drawn widespread market attention and turmoil, particularly affecting the European market.
In this context, the cryptocurrency market has not been spared. A transfer of 400 million DOGE from an unknown wallet to Binance has sparked concerns about liquidity and price volatility. Additionally, the U.S. dollar index (DXY) falling below 105 has further exacerbated market uncertainty and volatility. The total cryptocurrency market capitalization has dropped below $2.2 trillion, with a 6.2% decline within 24 hours, highlighting extreme market instability.
Amid such a volatile market, investors face severe price fluctuations and increasingly stringent market regulations. For instance, New Zealand's tax authority has warned cryptocurrency traders to declare their income, reflecting a global trend towards stricter cryptocurrency market regulation.
MIMI's Stable Investment Strategies
To address market volatility, MIMI employs robust investment strategies designed to provide secure and reliable returns for users. We ensure users can achieve stable returns under market conditions through technological innovation and risk management.
Our multi-chain aggregation technology allows users to seamlessly operate and manage assets across different blockchains, effectively diversifying the risks associated with single-chain operations. By spreading investments across multiple blockchains, MIMI reduces the impact of market volatility on individual assets, enhancing the overall stability and security of investment portfolios.
MIMI offers a range of low-threshold liquidity yield products. These products, driven by smart contracts and A.I. technology, can analyze market data and user behaviour in real-time to optimize fund allocation. Smart contracts automatically execute investment strategies, ensuring funds achieve maximum returns at the optimal time and in the best projects. Through extensive data analysis, A.I. technology further enhances investment decisions and yield distribution by identifying the best investment opportunities and risk points.
Regarding specific investment strategies, MIMI adopts diversification and risk-hedging approaches. The diversification strategy allocates users' funds across different asset classes and projects to mitigate the risk of single-asset volatility. The risk hedging strategy uses financial instruments like options and futures to offset the adverse effects of market fluctuations. Through these strategies, the MIMI platform maintains stable growth of user assets amid market turbulence.
User Return Protection Mechanism
The MIMI platform employs transparent and efficient mechanisms to ensure investment security and stable returns for users.
Our return distribution mechanism is based on smart contracts and blockchain technology, ensuring all distribution processes are open and transparent. Smart contracts automatically execute return distributions according to preset rules, avoiding human errors and unfairness. All distribution and fund flow data are recorded on the blockchain, allowing users to view and verify them anytime.
We also optimize fund allocation and investment strategies through A.I. technology and data analysis. The A.I. system analyzes market data in real time, identifies the best investment opportunities, and adjusts fund allocation based on market dynamics, ensuring the most efficient use of user funds.
The MIMI platform employs multi-signature and permission management mechanisms to safeguard user returns further. Multi-signature technology requires multiple independent key holders to sign transactions for execution jointly. This prevents single key theft and enhances transaction security and credibility.
Through innovative technologies and stable strategies, the MIMI platform provides a safe, transparent, and efficient investment platform amid global market volatility and tightening regulations. Our multi-chain aggregation technology, smart contract applications, and AI-driven investment strategies optimize fund allocation, reduce investment risks, and ensure users achieve stable returns under any market conditions.
In the future, MIMI will continue to focus on technological innovation and market expansion, maintaining a leading position in the blockchain financial sector. We will continuously optimize our platform's services and products to meet users' diverse needs. MIMI invites more users and partners to join us in promoting the sustainable development of blockchain technology and enjoying safe, transparent, and convenient financial services.

1,917,088 | Fetching Data Dengan Alpine JS | Kali ini kita akan belajar fetching data dari API dengan menggunakan Alpine JS. Kita akan buat... | 0 | 2024-07-10T12:57:26 | https://dev.to/mahib22/fetching-data-dengan-alpine-js-4l15 | javascript, alpinejs, fetch, api | Kali ini kita akan belajar fetching data dari API dengan menggunakan Alpine JS. Kita akan buat website yang menampilkan daftar klub sepak bola yang bermain di Liga Premier Inggris yang diambil dari API [berikut](https://www.thesportsdb.com/api/v1/json/3/search_all_teams.php?l=English%20Premier%20League).
[Alpine JS](https://alpinejs.dev/) merupakan sebuah lightweight framework Javascript yang dapat kita manfaatkan untuk membuat sebuah interaktif website tanpa harus menggunakan framework seperti React atau Vue. Ketika menggunakan Alpine JS kita dapat dengan mudah langsung menerapkan sifat Javascript ke dalam file HTML tanpa perlu menuliskannya secara terpisah.
Silahkan buat file HTML dengan nama _index.html_, kemudian sisipkan kode berikut.
```
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Latihan Alpine JS</title>
<!-- Import Alpine JS -->
<script defer src="https://cdn.jsdelivr.net/npm/alpinejs@3.x.x/dist/cdn.min.js"></script>
<!-- Import Tailwind -->
<script src="https://cdn.tailwindcss.com"></script>
<!-- Google Fonts -->
<link rel="preconnect" href="https://fonts.googleapis.com" />
<link rel="preconnect" href="https://fonts.gstatic.com" crossorigin />
<link href="https://fonts.googleapis.com/css2?family=Roboto:wght@300;400;500;700&display=swap" rel="stylesheet"/>
<style>
* {
font-family: "Roboto", sans-serif;
}
</style>
</head>
<body>
</body>
</html>
```
Selanjutnya kita akan membuat komponen card menggunakan Tailwind CSS.
```
<div class="container px-4 py-12 mx-auto">
<div class="flex flex-wrap">
<div class="lg:w-1/4 md:w-1/2 p-4 w-full">
<img alt="logo" class="object-cover h-56 mx-auto" src="" />
<div class="mt-4">
<h2 class="text-gray-500 text-xs tracking-widest mb-1"></h2>
<h1 class="text-gray-900 text-xl font-medium"></h1>
</div>
</div>
</div>
</div>
```
Kemudian kita akan melakukan fetching data dan menampilkannya pada komponen card.
```
<div class="flex flex-wrap" x-data="{ teams: [] }" x-init="fetch('https://www.thesportsdb.com/api/v1/json/3/search_all_teams.php?l=English%20Premier%20League').then(response => response.json()).then(data => { teams = data.teams })">
<template x-for="team in teams">
<div class="lg:w-1/4 md:w-1/2 p-4 w-full">
<img x-bind:alt="team.idTeam" class="object-cover h-56 mx-auto" x-bind:src="team.strBadge" />
<div class="mt-4">
<h2 class="text-gray-500 text-xs tracking-widest mb-1" x-text="team.strLocation"></h2>
<h1 class="text-gray-900 text-xl font-medium" x-text="team.strTeam"></h1>
</div>
</div>
</template>
</div>
```
Selamat! Anda berhasil melakukan fetching API dengan menggunakan Alpine JS dan menampilkannya kepada pengguna, berikut ini adalah hasilnya.
Berikut ini penjelasan dari kode yang dibuat.
**x-data** berfungsi untuk menampung data logic Javascript agar berjalan langsung pada tag HTML tersebut. Pada kode tersebut kita membuat satu variabel dengan nama teams yang bertipe data array. Variabel ini bertujuan untuk menampung data hasil fetching pada fungsi tersebut.
**x-init** bertujuan untuk melakukan inisialisasi sebelum komponen tersebut di load. Pada kode tersebut kita menyisipkan fungsi fetch yang bertujuan untuk mengambil data dari endpoint API yang sudah kita siapkan sebelumnya. Kemudian sebelum halaman browser ditampilkan, Alpine JS akan melakukan proses fetching di belakang layar kemudian hasil dari fetching tersebut ditampung kedalam variabel teams yang sudah dideklarasikan di awal.
**x-for** digunakan untuk melakukan proses perulangan dari variabel teams kemudian ditampung kembali dalam variabel team.
**x-bind** untuk menampilkan gambar dan **x-text** untuk mencetak langsung data kedalam tampilan HTML. | mahib22 |

One powerful tool that has gained prominence is the QR (Quick Response) code. These codes have evolved from their origins in inventory tracking to becoming a versatile tool for marketers. With [Divsly](https://divsly.com/?utm_source=blog&utm_medium=blog+post&utm_campaign=blog_post)'s state-of-the-art [QR Code Generator](https://divsly.com/qr-code-generator?utm_source=blog&utm_medium=blog+post&utm_campaign=blog_post), businesses can leverage this technology to enhance their marketing campaigns and engage with customers in innovative ways.
## Understanding QR Codes
Firstly, let's delve into what QR codes are and why they matter. QR codes are two-dimensional barcodes that store information in a matrix pattern. They can be scanned using smartphones equipped with a QR code reader, instantly linking users to websites, digital content, or specific actions like making a purchase or accessing exclusive offers. This ease of use makes QR codes highly effective in bridging the gap between offline and online marketing efforts.
## The Role of QR Codes in Marketing
QR codes have become integral to modern marketing strategies for several reasons:
**Enhanced Customer Engagement:** QR codes offer a seamless way for customers to interact with brands. Whether it's scanning a code to visit a product page, participate in a contest, or receive promotional discounts, QR codes facilitate direct engagement.
**Tracking and Analytics:** Marketers can track QR code scans to gather valuable data on customer behavior and campaign effectiveness. This data helps in refining marketing strategies and understanding consumer preferences.
**Cost-Effective Solution:** Implementing QR codes in marketing campaigns is relatively inexpensive compared to traditional advertising methods. It allows businesses of all sizes to enhance their outreach without breaking the bank.

**Educational Resources:** Generate QR codes for educational materials, enabling students to access supplementary content, quizzes, or instructional videos directly from textbooks or classroom materials.
## Best Practices for Implementing QR Codes
To maximize the effectiveness of QR codes in your marketing campaigns, consider these best practices:
**Placement:** Ensure QR codes are placed in prominent locations where they are easily visible and accessible to your target audience.
**Clear Call-to-Action (CTA):** Accompany QR codes with a clear and compelling CTA instructing users on what to expect upon scanning, such as "Scan to Get 20% Off Your Next Purchase."
**Testing and Optimization:** Regularly test QR codes across different devices and environments to ensure compatibility and functionality. Optimize QR code designs based on performance analytics to achieve better engagement rates.

So you can use **[SMS Surveys](https://www.zonkafeedback.com/sms-surveys)** as a reliable medium to gather feedback from your customers.
## Why is Delivery Feedback Important?
Imagine you order a dress online. Your order is placed within seconds, and you get a notification of receiving your product within two days. But you do not get it for seven days, and you miss wearing it on occasion, which was five days after you placed your order. How would you feel? Of course terrible, because the delivery is very late than expected and ruined the wholesale purpose of buying that dress.
Similarly, if you receive the delivery on time, but the delivery staff is impolite, you will never feel good while taking delivery because it will make your Delivery Experience awful and ultimately affect your overall shopping experience. You may choose to switch to another online shopping platform or delivery service.
The same is with your customers. So if you are into the online store business, you cannot afford to ignore the delivery aspect.
## Why use SMS Surveys for Delivery Feedback?
The online orders process includes registering a mobile number, and most of the online orders are made through phones only. Whether ordering a pizza or purchasing a dress for a party, a phone number is mandatory to provide. Therefore, SMS becomes a channel that you can use anytime to provide information about the customers’ orders.
You can provide delivery status like ‘Packed,’ ‘Out for Delivery,’ or ‘Delivered’ through SMS. Similarly, you can use this channel to send short surveys to the customers to obtain Delivery Feedback.
Although channels like Email and social media are also accessible easily with the increased use of smartphones, still, SMS is an unbeaten mode of communication that never loses its value. 75% of the young generation also prefer to receive communications regarding deliveries, promotions, and surveys through text messages. Here are some Benefits of SMS surveys to be sent to obtain Delivery Feedback.
## Useful Features of SMS Surveys for Delivery Feedback
Here are some features of SMS Surveys that make them helpful in collecting Delivery Feedback.
1. SMS **[Survey Tools](https://www.zonkafeedback.com/blog/online-survey-tools)** can be integrated with your POS and Delivery platforms
2. SMS Surveys can be scheduled
3. SMS Surveys can be customized and personalized
4. SMS Surveys can be tracked
Let’s learn more about these benefits and how you can derive them.
## 1. SMS Survey Tools can be integrated with your POS and Delivery platforms
It is nearly impossible to manage to send SMS Surveys to all your customers manually in a real-life scenario. That's why it's a great idea to integrate your SMS Survey Tool with your Point-of-Sales and Delivery platforms. With integration, you can set up rules to trigger SMS Surveys once the status of the order changes to 'Delivered' in your POS or delivery platform. This ensures that your SMS Surveys are sent seamlessly and automatically at the right time.
## 2. SMS Surveys can be scheduled
Another benefit of sending SMS Surveys is that you can schedule them as per your requirement. With SMS Survey Tools, you can also set delays in sending your Feedback SMSes. For instance, if you're seeking feedback about the product quality and not just the delivery, it may be ideal sending the SMS after a delay of 3 days instead of right away. This will give your customers enough time to experience the product. Similarly, it is a great idea to send the Feedback SMS after 2-3 hours in case of food delivery, giving the customer enough time to have had their meal.
## 3. SMS Surveys can be customized and personalized
You can ask any questions you like in your surveys and completely customize them. You can also white-label them by adding your company branding, logo, background, and more, and set your SMS Sender ID as well. Add logic to make your SMS Surveys more intuitive. For instance, if your customer is unhappy with the delivery (based on your first survey question), follow it up with a question to ask the reasons for dissatisfaction. You could give this as a comment box for customers to share their opinion or give them options to choose from like packaging, delay, quality, etc.
You can also personalize your SMS when sending the survey. Include customers' names, refer to the product they purchased or any other identifiable information, including your brand name, and more to put a better impression and help improve response rate. Studies suggest that 80% of customers are likely to make purchases from a brand providing them a personalized experience compared to other brands.
You also get the option to personalize your SMS surveys as per the product and delivery. You can use placeholders for this purpose. Placeholders help you insert details like the Customer’s Name, Product Purchased, and any other information relevant to the order or delivery required in the SMS. In this way, you don’t need to draft a new message manually every time. It will automatically take the details and include them in the content of the text message.
You can collect Delivery Feedback through SMS whenever a delivery is involved in your business. Be it a courier delivery or a food delivery; Delivery Feedback is relevant for all, and SMS is the best way to gather it. Here are some use cases of SMS Surveys for gathering Delivery Feedback.
## 4. SMS Surveys can be tracked
With Zonka Feedback, you track all the SMS Surveys you sent — view how many SMSes were sent, to whom, and when. Check delivery dates and time. View if the survey was opened and was responded to or not.
1. Using SMS Surveys for Delivery Feedback
2. Feedback for Product Delivery
3. Feedback for Restaurant and Food Delivery
4. Delivery for Couriers and Packages
Let’s explore how and where you can use SMS Surveys for obtaining Delivery Feedback.
## 1. Delivery of Products purchased through Online Shopping
Online shopping has become a part of the lives of many. There are different types of products that people purchase online. Be it clothes, linen suits, accessories, decor items, groceries, or even medicines; almost all products are available online for people to buy. Especially after the advent of the pandemic of COVID19, online shopping has increased to a large extent. 49% of the global customers do more online shopping than they used to do before the pandemic, and this number is 62% in the U.S.
As online shopping increases, so is the home delivery of products because delivery is a significant part of online shopping. It is something that strongly affects customers’ experiences. You can use Delivery Feedback Surveys to gauge satisfaction about various aspects of product delivery:
- If you want to capture only delivery feedback, it is ideal sending a **[delivery survey](https://www.zonkafeedback.com/blog/customer-satisfaction-survey-questions-for-delivery-business)** right after the product has been delivered. Here is an example:
`Hey [Name], thanks for purchasing with us. Your [product] was delivered today at [time]. We would love to know your delivery feedback. [Feedback Link] - [Company Name]`
If you want to obtain feedback regarding the quality and satisfaction with the product, it is ideal to schedule it 2-3 days after the delivery. Here is an example:
`Hey [Name], thanks for purchasing with us. Your [product] was delivered on [date]. We would love to know your feedback about how satisfied you are with the product quality. [Feedback Link] - [Company Name]`
You can also use these templates for creating delivery feedback surveys.
Using SMS Surveys for Delivery Feedback will ensure you get the accurate picture and customer insights of how the delivery of your products was. You can trigger SMS Surveys to be sent to the customers as soon as delivery happens and the status is changed to ‘Delivered’.
## 2. Food Delivery and Restaurant Home Delivery Feedback
Like online shopping has increased, the delivery of food has also increased to a large extent. Researches suggest that every year, food delivery in the U.S. increases by 20%. Moreover, the pandemic has also led to the fast growth of food delivery globally. People don't feel safe and comfortable eating outside. 43% of Americans feel more comfortable getting home delivery of food rather than dining at a restaurant.
So if you have a restaurant or a takeaway restaurant, Food Delivery is a significant area to focus on. Delivery has a substantial effect on the quality of food delivered. Delay in food delivery can finish the freshness of food and make the food items stale and difficult to consume.
Moreover, the behavior of your delivery staff directly showcases your hospitality. So you need to ensure your delivery staff behaves in a pleasant like your waiters act with the customers at the restaurant. A Delivery Survey helps you to do that. You can ask these types of questions in a Food Delivery Survey:
- How was the delivery?
- Was the delivery person courteous?
- Was the food delivered on time?
- Was the food delivered packaged well?
- Was the food hot and fresh when delivered?
For this purpose, you can trigger SMS surveys as soon your delivery staff delivers the food. Here is an example of a survey message you can send to collect food delivery feedback.
`Hey [Name], thanks for giving us an opportunity to serve you. Your food was delivered today at [time]. We would love to know your feedback about how much you are satisfied with the quality of food and delivery service. [Feedback Link] - [Company Name]`
Sending a Delivery Survey at the right time will enable you to get real-time customer insights. You will be in a position to improve Customer Experience in case you receive negative feedback. If you send SMS Surveys just after delivery, the customers can share their experience, and you can quickly take appropriate action on it. This way, you can even convert negative feedback into a positive one.
## 3. Delivery of Couriers
Delivery of Couriers across the globe is increasing. The global courier industry consists of more than 580,950 businesses employing around 4.1 million people. Reports suggest that the sector recorded a growth of 4% than the previous year, with total revenue amounting to $325 billion in 2019.
If you are into Courier services, delivery of goods is the mainstream work in your business. Here, capturing Delivery Feedback becomes a priority because Delivery Experience is the only thing that can take your business towards success or failure.
So whenever you deliver a shipment, you should send SMS Surveys to your customers. You can also send messages informing that the consignment is delivered and, in the same SMS, include a survey link asking for feedback. Here is an example of such a message:
`Hey [Name], thanks for using our courier services. Your shipment was delivered today at [time]. We would love to know your feedback about our courier services. [Feedback Link] - [Company Name]`
Sending such a message and capturing Courier Delivery Feedback will enable you to know about and improve the Customer Experience by focussing on the improvement areas of your delivery service.
You can use SMS Surveys to capture Delivery Feedback in all the above cases and any business where delivery of goods is involved. | kaumudi_tiwari_500ea164e7 |

## Having An Effective Communication Skill
Excellent written as well as verbal communication is the most pivotal skills for QA managers. As a QA manager, you need to:
* Effectively report the overall status of his team to higher management.
* Ability to communicate properly with non-technical as well as technical people, especially explaining the technical challenges to the management team.
* Should be able to diplomatically deny any request from higher management or the development team when the overall product quality is not perfect for release.
Conducting regular meetings also falls among the duties of a manager.
* If the team is large, formal meetings should be conducted regularly where the agenda should be discussed prior to the meeting and a MOM should be sent to the team members after the meeting.
* If the team is small, pre and post-meeting MOM is not necessary, a basic stand up meeting will be perfect.

Just enter the URL in the mobile site tester to test site’s compatibility across 50+ device viewports. **
## Problem Solving
Once I worked on a project where the testing team faced a fast transition from manual to automation. Initially, when the team worked on [manual testing](https://www.lambdatest.com/learning-hub/manual-testing), the test cases were not that much detailed since testers understood what they needed to do in each test cases. But when [automation testing](https://www.lambdatest.com/automation-testing) came into play, multiple problems surfaced.
Automation testers who were hired did not understand the test cases as they were not detailed enough. Here are the ways to [write effective test cases](https://www.lambdatest.com/blog/how-to-write-test-cases-effectively/). The tool they used could not support the bulk export of test cases and finally, the team had to answer to the management regarding where their work was blocked.
Problem-solving ability is a crucial skill for QA managers to deal with such unprecedented scenarios effectively.
If your project is developing a web application, the most common issue often faced is [cross browser compatibility](https://www.lambdatest.com/learning-hub/cross-browser-compatibility). If your project is in Agile, cross browser compatibility may not be specified in the requirement but may come as an enhancement request later on, once a demo is scheduled and the stakeholder finds out that the application is failing to render on the certain browser running on specific devices.
It is a best practice to incorporate the execution of [cross browser testing](https://www.lambdatest.com/online-browser-testing) in every sprint since it will take a lot of effort to do the testing of the entire application if cross browser compatibility comes later on as an additional request.

Easily test on 3000+ desktop & mobile environments. **
You can deal with such situations with such unprecedented scenarios by:
* Training the testers from the beginning to follow standard procedures to avoid less detailed and bulky test cases.
* Use mind maps and checklists which can replace the test cases.
* Sort the problem according to complexity, start by solving the problem with minimum risk and complexity and move up higher.
For this, you can leverage cloud-based testing platforms like LambdaTest. It is an AI-powered test orchestration and execution platform that allows you perform manual and [automated testing](https://www.lambdatest.com/learning-hub/automation-testing) at scale on over various browsers, devices, and platforms combinations. With this, you can ensure your websites or web apps are cross-browser and cross-platform compatible.

Discover its features, uses, and best practices for optimal performance.
**
## Hawk-Eyed Gaze Over Analytics
Another critical skill for QA managers is the ability to analyze the data with a keen eye for monitoring granular level details. Instead of only proving that an application is working fine, a QA manager should guide his team and in fact, work himself to recognize errors that are hidden. As a QA manager, you should be able to detect anomalies and guide your team on how to resolve it along with formulating a resolution strategy. Not only that, having a keen eye for details will also require him to take a quick look at the overall application and check if anything looks off when compared to the requirement specification.
## Be Adaptable + Influential
People don’t like change, especially when it comes to the way they are doing things and having no problem while doing their job. However, you must adaptability and influence, are counted as a highly relevant skill for QA managers. As their job is to find out ways that make the team’s work easier and faster. Especially, in the current age of Agile when the stakeholders expect faster delivery, you must bring in a change to ensure that your team does not lag behind in comparison to others. As you bring something new on-board, it is important to encourage your colleagues and teammates to adapt the same for better productivity, individual output, and collective delivery.
* Conduct an audit to find out if anything is wrong in the existing process, for example — the team may be facing a problem to maintain test scripts which are quite similar.
* Discuss with the team and find out their opinion regarding what needs to change, for example setting up data-driven tests.
* The final step is to implement the change and convincing the higher management why this change is required.

## Visualization & Prioritization Of Business Scenarios
A test manager must be able to get an abstract idea from the client provided specs and visualize a real-time business situation. He must also be able to be ready for a knowledge sharing session with either his team or higher management if the situation arises. In short, the manager must also be able to play the role of a business analyst.
Apart from analyzing complex issues, visualization and prioritization of business scenarios are indispensable skills for QA managers. As a QA manager, you must also be able to anticipate a complex issue fluently by taking a look at the requirement. System simulation should fall among the qualities of a good QA manager. He should not focus on a particular defect, instead, he should focus on how a particular defect will impact the bigger picture. Since it is not possible for the entire team to block time for a brainstorming session, the manager should always be ready to help any resource in terms of sharing business knowledge as required.

**
## Time Management — Crucial in the Agile World
If you want to become a good QA manager, you should be able to adapt yourself as well as your time to keep in pace with the Agile world. You must always be ready to deal with the client whenever any critical change in the requirement arrives.
If your team is not able to deliver the work within the deadline, the blame will come upon you. Time management is a definite skill for QA managers, especially in the current world of DevOps and Agile. You along with your team should always be ready with the deliverables so that the management does not face any need to extend the deadline.
My suggestion to you would be to go for a good project management tools such as Jira, Asana which would offer a dashboard to help everyone understand what every member of the team is doing and when? Using a custom IM(Instant Messaging) web app such as Skype, Slack etc. would also help in collaborating better to pace up the project delivery. Here are top [collaboration tools](https://www.lambdatest.com/blog/collaboration-tools/?utm_source=hashnode&utm_medium=organic&utm_campaign=july_09&utm_term=vs&utm_content=blog) for your software testing team.
## Have a Strong Base in Programming
Programming languages are a must-have skill for QA managers. With the growing usage of automation tools, QA managers must also have a strong programming base to keep up with their team as well as understanding what the client needs. What programming language you should learn depends on the automation script used by your organization. For example, if your team works with [Selenium WebDriver](https://www.lambdatest.com/learning-hub/webdriver?utm_source=hashnode&utm_medium=organic&utm_campaign=july_09&utm_term=vs&utm_content=learning_hub), you should have knowledge in JavaScript.

**
On the other hand knowledge of Java or web services is needed if your project is using UFT. Apart from that, knowledge of SQL is something that every manager should possess no matter what automation tool your company is using. Apart from that, you should know the core fundamentals of BDD and object-oriented programming. This includes practical knowledge of Python, Ruby, and Perl as well. Here are the top [programming languages for automation testing](https://www.lambdatest.com/blog/top-programming-languages-helpful-for-testers/?utm_source=hashnode&utm_medium=organic&utm_campaign=july_09&utm_term=vs&utm_content=blog) that testers can use.
## Strong Negotiation Skills
The situation may often arise when you need to convince the stakeholders or higher management that their expectation from your team is not possible in real time. Let me explain by giving an example.
I’ve faced situations when the delivery deadline was getting nearer and some critical defects were not fixed yet. The development team’s priority was always high to the management and the testing team started getting emails to “cover it up” and pass the test case.
Often the same thing happened when stakeholders used to pick a “defect” even when everything was working fine as per requirement.
In case of the first scenario, a good QA manager should be able to diplomatically fight with the management explaining why his team is doing the right thing and how letting a critical defect go unfixed will impact the product or company’s reputation in the long run.
In the second scenario, the manager’s negotiating skill as a BA will matter most since he will be required to discuss with the stakeholder and point out how everything is working fine as per requirement. Remember, negotiating well is a skill for QA managers that all companies seek to have.

**
## Be A Team Player
Quality of a good QA manager is to build up a “dream” team where the members, besides being skilled, appreciate each other’s work and behave more like a family where they cooperate, help each other and appreciate others as well. To build up a great team, you must
* Organize budget-friendly events that involve team building activities and games.
* During the lunch hours, take out your team together for lunch and have discussions on non-technical topics so that the team members become friendlier with you as well as among themselves.
* Encourage your QA team to help and cooperate, other teams, especially the development team.
* The most organization allows a quarterly or half-yearly budget to the project that is to be spent on events or parties. Even if your company does not have that, encourage your team to organize parties or outings where they can have a good time together not as colleagues, but as friends.

## Willingness To Help Your Team Members Grow As An Individual
This is one skill for QA managers that is often missed out by many. Stress is always going to be a part of your SDLC, due to narrow project deadlines. However, you should not stop individual growth for any resource who is working under your team. As a QA manager, you should remember to help your team members grow in their career. So that eventually when they become a manager, they follow you as an inspiration and help their resources, the same way as you did.
* Start by spreading the best practices which you learned in your overall career as a quality analyst or a QA manager.
* Organize internal as well as external training. Motivate your team members to attend those training by explaining how it will help in their career.
* Work in a group to share the competencies among the entire team.
* Also, don’t keep your team members too busy. Allow them some time and let them learn a few things by themselves. Especially if one of your team members is a fresher, start by keeping his workload light with no hurry or deadline so that he can learn to complete the work by himself without taking any help from the seniors.
## Be Bold and Confident
Confidence! A primary skill for QA managers around the globe. A manager acts like the leader of the entire team. And self confidence is the base of leadership. Be bold and confident whenever you are about to express your opinion to your superiors or your team. Let’s suppose the stakeholder of your project is making a sudden change request just when delivery time is getting closer. If you are not bold enough to politely refuse his request thinking that what the management or the client will think about you, your entire team will suffer because of the unnecessary work. Even the higher management will not like it that being a QA manager, you accept whatever requests the stakeholders make. Yes, the person on the other side may be superior in terms of designation, but if you think that your decision is right, you must not be afraid to act on it.

## Be Skeptical For Traditional Prejudices
A good relationship between different teams in a project adds a lot of value to the company’s overall work culture. As a QA manager, you can either contribute to an inspiring environment or foster a pessimistic work culture.
A criticized product of the traditional waterfall model is the conventional “testers vs developers” mentality, that separated the process, timeline and role among developers and testers. This mentality still exists with the advancement of [continuous testing in DevOps](https://www.lambdatest.com/blog/how-to-implement-continuous-testing-in-devops-like-a-pro/?utm_source=hashnode&utm_medium=organic&utm_campaign=july_09&utm_term=vs&utm_content=blog) and Agile.
If you keep on fostering this superstitious mentality, a barrier gets created between testers and developers, resulting in conversation barriers in the worst case, which can impact the quality of a product. Discourage if you spot any team member behaving like this and try to find out the root cause of why this belief is existing in your team?
## Read The Situation — Know When to Step in or Step Aside
You must trust your team and know what your team members are capable of. They must not always depend on you to guide them and sometimes, they should be able to figure things on their own. A team that is high performing does not need any tool, process or person standing in their way. Those teams always take the initiative and are self-directing. If you step in too often, the testers will get a message that they are required to come to you before taking any decision and ask for permission. This will reduce the team’s moral and impact their work.
However, if you don’t step in when required, the work will definitely be impacted. Use your intuition and take a situational approach to decide where your presence is needed, and thus, help your team accordingly, instead of depending on contemporary procedures.

## So, What Makes A Good QA Manager?
Is it is technical skills, the certifications, years of experience in software testing or keeping up with the current testing trends such as [shift-left testing](https://www.lambdatest.com/learning-hub/shift-left-testing?utm_source=hashnode&utm_medium=organic&utm_campaign=july_09&utm_term=vs&utm_content=learning_hub), IoT, [automated testing](https://www.lambdatest.com/learning-hub/automation-testing?utm_source=hashnode&utm_medium=organic&utm_campaign=july_09&utm_term=vs&utm_content=learning_hub) and more!
Well, you need all of that, but most importantly you need an ability to create and work with a creative team where each and every member are equally valuable and irreplaceable for the organization. You need to understand your role as a manager as well as how to effectively use your leadership skills which will not only make our team stand out, but also make you inspiration in the eyes of your team members. All the best!

Let's get to it.
## the climb.
I started in the worst possible position as a web developer: CTO. I started my own company, had no professional experience whatsoever, just a box of tools that I barely knew how to use, and the confidence that goes with any idiot that just came out of a double degree in entrepreneurship and software engineering. In other words, I was a ticking time bomb, the most fertile ground you could think of for a proper burnout. And Burn out I did.
I didn't know how to code properly, yet I was coding. I never stopped to think and reflect on my life, mostly because I had no life. I had customers, and I was a slave to my "product". And my product was shite.
But we had customers. So I pushed on. And when we finally crashed, what did I learn ? Did I find a job as a junior developer in a nice company that could help me get better through the help of a wise, caring mentor ?
No sir. I made the complete opposite. I started another company. And guess what. Second burnout in a row. Long story short, it took a miracle to get me out of here: I won a hackaton, that earned me a trip around the globe. Finally, I had time to breathe. And I learned the first importants lessons:
- In between jobs, take some time off. Relaxation is not a reward, it's a requirement toward any meaningful achievement.
- Start small. Be Humble. Sites like [roadmap](https://roadmap.sh/) can help you tremendously. Because in life, everything valuable takes time.
- It's OK to ask for help, both for your job and in your life.
## the peak
after 3 years of building abominations through carefully sabotaged codebases, I decided it was time to move on. And so, I joined the worst best company of my career.
This company had everything a 27yo could ask for: early stage, young team, only rowdy guys (our slack history would send us all to jail), afterwork twice a week, and a codebase that was so toxic it's a miracle it didn't spontaneously exploded. but boy did we have fun adding GIFs and sparkles and hover effects.
And guess what ? Another terrible thing happened. We raised funds. Like, a lot.
Raising funds when your product is unstable is not unlike throwing water at a raging kitchen oil fire. You're in for a nasty surprise. And when your customers start asking for simple features, but your codebase is but a glorified diarrhea, you start to think "hmm, maybe we should have used Typescript".
Because asking the following questions really hurts:
- Why does our landing page take 8 seconds to load ?
- Was it such a good idea naming that variable "x" ?
- How did we manage to turn our most important user story into a 1800 lines function that is, obviously, not tested ?
So, we did what we had to do. And it felt soooo good.
```sh
rm -rf client
rm -rf api
```
Yup. We started new. And let me be clear: the only reason we could do so was because we raised funds. We were overpaid kids playing around with bits of code that had nothing to do with our core product.
it took us 2 months to rebuild the app, with the help of a great freelancer that helped us design, build and test the app.
For the first time in my career, I understood what it meant to believe in a product, to fight for it, and to nurture it. Our backlog slowly started to pile down, our customers were happier than ever. But karma is a bitch, the pandemic came, we "crashed" (AKA, the company didn't have any money to pay the tech team), so we all left, hoping that things would get better, but just like pauses don't work in relationships, they don't work in jobs either. I moved on, and evolved into a brand new kind of idiot. But in the mean time, I learned some new lessons:
- Building a great product takes time and conviction
- Its a good thing to have a nice team. It's better to have a good team. It's a miracle to have a team that is both benevolent and efficient.
# the fall
From 2020 to early 2023, I never managed to keep a job for more than a few months. Why ?
Because I was stupid. That's why. Here's a program to completely fuck up your life:
- Be nice and charming
- A company reaches out to you
- Interviews go well, because you are self-confident
- Your get hired.
- You're good at talking, but not good at coding
- Because you have 6/7/8 years of experience, your salary is HUGE.
- Company slowly realises that you are not qualified for the job.
- Everyone loves you, except the people that work with you on a daily basis. Think "Oh, we just hired a golden retriever to code our most anticipated feature. He can't code whatsoever, but he's a GOOD BOI"
- HR thanks you and ends up your introductory period.
- back to step one.
I did this not one, not twice, but 5 times in a row, blissfully happy, not realising that the only reason I was getting hired was because I'm good at selling myself. After the 5th failure in a row, karma struck me. And almost killed me. Literally. But more on that later: the main issue with this endless cycle was that staying in a company for such a short amount of time is not enough to make you better: you cannot get a grasp on the product, you do not have enough time to start building something meaningful, and because I was not good at coding, I couldn't even help the junior devs (who were sometimes better than I was).
So I learned the most important lesson of them all:
- I suck, and that's alright, as long as I'm able to acknowledge it and decide to get better.
Which leads us to the main part of this story
## the forge
Early 2023, I started reading. A lot. About coding, about health, about habits. And I completely reshaped my life.
Here is the complete path I took:
## Acknowledge
You have to understand that the quality of your work is merely a reflection of your life, and therefore, of your habits. And my habits were a mess. From video games to sleepless nights, from alcohol to sedentary lifestyle, I had it all wrong.
I used Google calendar to write down what my weeks look like. Every single thing, from sleep to work to fun. And I picked 3 things I wanted to change.
- Take care of my health
- Stop playing video games
- get better at coding
## Act
So, that's all I did. I removed everything that was not aimed toward that goal. Sold my gaming computer, subscribed to a weekly delivery of healthy food, set my alarm clock to 6 in the morning, hit the gym. It took me 3 months to turn this into a routine.
Here's how the day unfolds now:
- wake up at 6AM
- Drink water
- hit the gym for 60 minutes
- cold shower
- Get to work
- set my to-do list using calendar
- Get back home
- read/practice guitar
- No more screen time after 9PM
- Sleep at 10PM
My instagram feed went from cat videos and sexy girls to self-help and music. My youtube feed went from video games to coding tutorials and self-development. My salary more than doubled over 18 months.
but here are the key insights:
- Went from 4/5 MR a week to 3/4 a day
- Went from 20+ comments per MR to 1/2
- Went from "senior" to lead developer
- Went from 68kg skinny fat to 84kg bulky (I'm 1.84m tall)
- went from bragging self-confident to silent self-confident.
## Track
Here is the single most important change that I made: I started taking notes. Meaningful notes. I use Obsidian as my note app.
- After a workout, I write down my weight, and how much I lifted. Reps, weight, everything.
- When learning a new skill/library, I write down valuable bits of code
- Every morning, I write down about the previous day. What did I do ? How did I feel ?
- Every valuable tutorial/post/video is turned into a new page.
- Tags and [Links](https://help.obsidian.md/Linking+notes+and+files/Internal+links) are your best friends.
- I organise my notes using [this method](https://www.youtube.com/watch?v=Xw3SkhB4dMk) and [this method](https://www.youtube.com/watch?v=hSTy_BInQs8&t=973s)
Taking notes is not only a great way to keep track of your progress, it also tremendously helps your memory. Reading documentation is not enough, you have to write down what you understood, challenge it, and then use it.
Here are the tools I use on a daily basis:
- Obsidian
- Google calendar
- Minimalist phone. Basically turned my smartphone into a Nokia 3310.
- Turned off all notifications
- Spotify. Hans Zimmer is the GOAT to get into a state of Flow. As a matter of fact, I'm listening to the interstellar OST while writing these lines.
- ChatGPT. It's only getting better and better.
- VSCode, zen mode.
And here are the last lessons that managed to reshape me.
- Your job is an extension of your day. Not the other way around.
- Do the things that matter first thing in the morning. There's nothing more frustrating that coming home after a long day of work and realise that you didn't do anything except work.
- understand that everything that is not an investment is a liability.
- Keep track of your progress. I use [obsidian tracker](https://github.com/pyrochlore/obsidian-tracker) to keep track of my habits, workouts and so on
- Be benevolent. Your goal should always be to either get better, or help people get better. Which is basically the same.
I hope this post will help you get better at whatever you consider to be important.

In today’s digital economy, data is a critical asset for businesses. Efficient management and governance of this resource are crucial for driving growth and innovation. As data-driven decision-making becomes increasingly important, implementing effective data governance strategies is essential for ensuring data quality, security, and compliance.
## Understanding Data Governance
Data governance involves managing the availability, usability, integrity, and security of data within an organization. It sets decision rights and accountability frameworks to ensure data is used appropriately. Effective data governance ensures that the right data is accessible to the right people at the right time, empowering businesses to leverage data for strategic advantage.
## Establishing a Data Governance Framework
Creating a robust data governance framework is the foundation of managing data assets effectively. Here’s how to get started:
**1. Define Roles and Responsibilities**: Set up a data governance team, often called a Data Governance Council or Steering Committee, including representatives from various departments such as IT, legal, operations, and business units. Ensure clear role definitions and responsibilities to promote accountability and streamlined decision-making.
**2. Develop Data Policies and Procedures**: Establish comprehensive policies covering data collection, storage, usage, sharing, and deletion. Align these policies with business strategies, legal requirements, and industry standards. Regularly update and communicate these policies to all employees to ensure consistent data practices across the organization.
## Implementing Data Security Measures
Data security is paramount in data governance. Protect your data assets by implementing robust security measures:
**• Encryption**: Secure data at rest and in transit using advanced encryption techniques.
**• Access Controls**: Implement strong passwords, multi-factor authentication, and role-based access controls.
**• Network Security**: Use firewalls, intrusion detection systems, and regular security audits to safeguard your network.
A comprehensive data security strategy should include ongoing monitoring and response plans to address potential breaches swiftly.
## Conducting Regular Audits and Compliance Checks
Regular audits and compliance checks are critical for maintaining data governance standards:
**• Internal Audits**: Conduct regular internal audits to identify and rectify areas of non-compliance.
**• Third-Party Audits**: Engage external auditors for an unbiased evaluation of your data governance framework.
**• Compliance Checks**: Ensure your data practices align with regulations like GDPR, CCPA, and HIPAA, especially in highly regulated sectors.
## Fostering a Culture of Data Stewardship
Creating a culture of data stewardship ensures that everyone in the organization values and practices good data management:
**• Training and Education**: Regularly train employees on data governance policies and best practices.
**• Transparency**: Promote transparency in data usage and decision-making processes.
**• Incentives**: Reward employees for adhering to data governance practices and contributing to data quality and security.
## Leveraging Technology for Data Governance
Modern tools and technologies can enhance your data governance efforts:
**• Data Management Platforms**: Use platforms that integrate data governance functionalities for seamless management.
**• Automation Tools**: Implement automation for routine data governance tasks to reduce manual effort and minimize errors.
**• Analytics and Reporting**: Use analytics tools to monitor data governance performance and identify areas for improvement.
## Conclusion
Effective data governance is essential for maximizing the value of your data assets while ensuring compliance and security. By establishing a robust framework, implementing strong security measures, conducting regular audits, fostering a culture of data stewardship, and leveraging technology, businesses can confidently navigate the complexities of data management in 2024.

Additionally, the arrow up and down keys didn't work either. This issue arises because MacOS doesn't come with OpenSSH built-in.
To install OpenSSH on your Mac, follow these steps:
1. First, check the version of SFTP you are using by entering the following command in the terminal:
```bash
which sftp
```
The output will look something like this:
```bash
/usr/bin/sftp
```
2. Install OpenSSH using Homebrew:
```bash
brew install openssh
```
3. After the installation, verify if SFTP is installed correctly by entering:
```bash
brew list openssh
```
After doing this, you can enjoy faster development and server access.

1,917,104 | Understanding Foreign Exchange: A Comprehensive Guide | Foreign Exchange, commonly known as Forex or FX, is the world's largest and most liquid financial... | 0 | 2024-07-09T09:49:47 | https://dev.to/ronny_odhiambo_dfd50cf0ee/understanding-foreign-exchange-a-comprehensive-guide-5ae8 | foreign, forex | Foreign Exchange, commonly known as Forex or FX, is the world's largest and most liquid financial market, where currencies are traded 24 hours a day, five days a week. The daily trading volume in the forex market exceeds $6 trillion, making it a hub for traders seeking profit opportunities. Whether you're a novice or an experienced trader, understanding the fundamentals of forex trading is crucial for success in this dynamic market.
## **What is Foreign Exchange?**
Foreign exchange involves the buying and selling of currencies. Unlike other financial markets, forex operates without a centralized exchange. Instead, transactions occur over-the-counter (OTC) through a global network of banks, brokers, and financial institutions. The primary participants in the forex market include commercial banks, central banks, financial institutions, hedge funds, corporations, and individual traders.
**Concepts in Forex Trading**
**Currency Pairs**
Forex trading is always conducted in pairs. A currency pair consists of two currencies: the base currency and the quote currency. The value of a currency pair is determined by comparing the value of the base currency against the quote currency. For example, in the EUR/USD pair, EUR is the base currency, and USD is the quote currency. If the EUR/USD pair is trading at 1.20, it means 1 EUR is equivalent to 1.20 USD.
**Bid and Ask Price**
The bid price is the price at which a trader can sell a currency pair, while the ask price is the price at which a trader can buy a currency pair. The difference between the bid and ask price is known as the spread. The spread represents the cost of trading and is a crucial factor for traders to consider.
**Leverage and Margin**
Leverage allows traders to control a larger position with a smaller amount of capital. For example, with 100:1 leverage, a trader can control a $100,000 position with just $1,000. While leverage can amplify profits, it also increases the potential for significant losses. Margin is the amount of money required to open and maintain a leveraged position.
**Pips and Lots**
A pip (percentage in point) is the smallest price movement in the forex market, usually equal to 0.0001 for most currency pairs. Lot sizes represent the volume of a trade. A standard lot is 100,000 units of the base currency, while mini lots and micro lots represent 10,000 and 1,000 units, respectively.
## **Fundamental and Technical Analysis
**
**Fundamental Analysis**
Fundamental analysis involves evaluating economic, social, and political factors that influence currency prices. Key indicators include interest rates, inflation rates, employment data, and geopolitical events. Central banks play a significant role in forex markets through their monetary policies, which can impact currency values.
**Technical Analysis**
Technical analysis involves analyzing historical price data and charts to identify patterns and trends. Traders use various technical indicators, such as moving averages, Relative Strength Index (RSI), and Fibonacci retracement levels, to make informed trading decisions. Technical analysis helps traders predict future price movements based on past performance.
**Benefits of Forex Trading**
Liquidity: The forex market's high liquidity ensures that trades can be executed quickly at any time.
Accessibility: Forex trading is accessible to individuals with relatively low capital requirements.
Diverse Opportunities: With numerous currency pairs to trade, there are ample opportunities to profit from various market conditions.
Flexibility: The forex market operates 24 hours a day, allowing traders to choose their trading hours.
**Risks and Challenges
**
Volatility: The forex market can be highly volatile, leading to significant price fluctuations.
Leverage Risks: While leverage can amplify profits, it also increases the risk of substantial losses.
Emotional Trading: Emotional decision-making can lead to poor trading outcomes. Developing a disciplined trading strategy is essential.
**Getting Started with Forex Trading
**
Educate Yourself: Gain a thorough understanding of forex trading through online courses, books, and webinars.

Here's a step-by-step guide to help... | 0 | 2024-07-09T09:52:26 | https://dev.to/jagadishwaran_g_c1d0a2786/how-to-install-the-python-1ig0 | Installing Python on a Windows 64-bit system is straightforward. Here's a step-by-step guide to help you through the process:
**Step 1: Download Python Installer**
Visit the Python official website: Go to python.org.
Navigate to the downloads section: Click on "Downloads" from the top navigation menu.
**Download Python:** The website should detect your operating system and offer the appropriate installer. You'll want to download the latest version of Python 3.x (e.g., Python 3.10.0). Ensure that you select the 64-bit installer unless you specifically need the 32-bit version for compatibility reasons.
Direct link to the Python download page: Python Downloads
**Step 2: Run the Installer**
Run the downloaded installer: Once the download completes, locate the downloaded installer file (typically named something like python-3.X.X-amd64.exe where X.X is the version number).
Launch the installer: Double-click the installer file to start the installation process.
Check "Add Python to PATH": On the first page of the installer, make sure to check the box that says "Add Python X.X to PATH". This will allow you to run Python from the command line more easily.
Customize the installation (optional): You can click on "Customize installation" if you want to modify the installation directory or choose specific components. For most users, the default options are fine.
**Begin installation: **Click "Install Now" to begin the installation.
Wait for the installation to complete: The installer will now install Python onto your system. This process usually takes a few minutes.
**Step 3: Verify Python Installation**
Check Python version: Once the installation is complete, you can verify it by opening a command prompt:
Type python --version or python -V and press Enter. This should display the installed Python version, confirming that Python is installed correctly.
Optional: Verify pip installation: Pip is Python's package installer, and it usually comes bundled with Python installations from version 3.4 onwards. To verify pip, type pip --version or pip -V and press Enter. This should display the installed pip version.
**Step 4: Set up Python Development Environment (Optional)**
Install a text editor or IDE: While not necessary for running Python, you may want to install a text editor or an Integrated Development Environment (IDE) for easier coding. Popular choices include Visual Studio Code, PyCharm, and IDLE (comes with Python). | jagadishwaran_g_c1d0a2786 | |

1,917,110 | Quickly Recover Your Outlook PST Passwords with PST Password Recovery Software: | Have you lost your PST password? Are you seeking a solution to unlock PST files without knowing the... | 0 | 2024-07-09T09:56:22 | https://dev.to/enzo_james_9c89d3e24d9ccc/quickly-recover-your-outlook-pst-passwords-with-pst-password-recovery-software-2ebh | outlookpstpasswordrecovery, pstpasswordremover, pstpasswordrecovery, outlookpstpasswordremover | Have you lost your PST password? Are you seeking a solution to unlock PST files without knowing the right password? You've arrived at the correct place and moment. Here is a simple guide for [removing forgotten passwords](https://www.linkedin.com/pulse/how-recover-pst-file-password-shoviv-software-13skc/) from PST Files. PST password recovery is a complex process for Outlook users. However, using a professional PST Password Recovery application, you can easily reset the PST password and open a password-protected PST file. In this article, I will assist all Outlook users who have lost their PST password.
## What is an Outlook PST file Password?
An Outlook PST file password is a security technique for storing and protecting the contents of a PST (Personal Storage Table) file in Microsoft Outlook. When a password is assigned to a PST file, it forbids unwanted access to the email, contacts, calendar items, and other data.
You can create a password when you create or update a PST file in Outlook.
This password protects your emails and other information from those who should not view them. When you try to open the PST file later, Outlook will ask you for the password. You won't be let in if you don't type it correctly.
## Password Protects PST Files: How?
Passwords provide a higher level of security for your computer data. Imagine you share a computer with others, and there are no separate accounts. To keep your emails private, you can use a password to lock your PST file. Outlook uses a method called CRC32 to do this. Once set, you'll need the password to open the PST file. It's straightforward to do this. You can use Microsoft Outlook to add a password to each PST file.
**Follow these simple steps:**
- To start, open Microsoft Outlook.
- Next, go to the taskbar and then click on Account Settings.
- Select Account Settings.
- In the Account Setting dialog box, go to the Data Files tab and choose the Outlook data file you want to protect with a password.
- Click on the Change Password button to set a password for the PST file.
- Now, please enter a password and confirm it by typing it again.
- You can also choose to save this password in your password list.
- Lastly, Click the OK button to save the changes.
Following these steps, you can easily add password protection to your PST files. Now that your mailbox data in the PST file is safeguarded, you'll need to enter the correct password every time you open Microsoft Outlook.
## Recovering PST Password Using Third-Party Software: A Solution for Forgotten Passwords
It can be frustrating if you need help remembering your PST password. Remember, you won't be able to open a password-protected PST file without the correct password. But what if you forget it? If you've noted down your PST file password somewhere, you're in luck because you can easily find it. However, if you can't recover the lost password alone, you might need a professional Outlook Password Recovery service. While a third-party program can't find your original password, it can unlock the PST file by creating a new password. There are many options online for PST Password Recovery software, but make sure to choose a reliable one before buying.
**Recommendation for a Third-Party Tool to Recover PST Password:**
While numerous options are available to recover your PST passwords, I recommend trying the **[Shoviv PST Password Recovery tool](https://www.shoviv.com/unlock-outlook-password.html)**. It's considered one of the best options for Outlook users. It works with all versions of Microsoft Outlook, even the latest version for 32-bit and 64-bit systems. Since PST files use a delicate encryption method called CRC32, this tool can quickly recover your PST passwords. This software lets you easily retrieve passwords of any language and length.
**Some features of the PST Password Recovery tool:**
- The Outlook PST Recovery tool lets you add many PST files without size limits.
- It quickly and efficiently removes, recovers, or changes passwords for numerous PST files you've added.
- You can unlock or reset passwords for PST files from older versions of Outlook, like 2016, 2013, 2010, and 2007.
- It can also handle PST files that are too big.
- Whether your PST files are in ANSI or Unicode mode, it's easy to unlock them.
- This tool works with all versions of Windows OP.
- Outlook PST Password Recovery in four easy steps:
- Install and open the software.
- Add your PST files.
- Click on the Recover Password button
- Choose one of the three provided passwords to unlock your PST files.
> Before buying the full version of the Shoviv Outlook PST Password Recovery tool, try out the demo version to unlock PST files up to 500 MB in size. If you need to unlock large files, you'll need to purchase the full version.
## Conclusion
Losing your Outlook PST password can be irritating, but there are options for recovering or resetting it. Using expert solutions, such as the Shoviv PST Password Recovery tool, makes the procedure simple and effective. Following a few easy steps, you can recover access to your password-protected PST files and secure your mailbox data. Remember to test the demo version before purchasing the complete product, and make sure you select a reputable alternative for PST password recovery. With the appropriate strategy, you can overcome the difficulty of forgetting passwords and protect your Outlook data.

```
GCWare services are not controlled by the unified start/stop command. The services controlled by the unified command are:
```sh
gclusterd, gcrecover, gbased, gc_sync_server, gcmonit, gcmmonit
```
**Separate Start/Stop Commands for GCWare Services:**
```sh
gcware_services all start
gcware_services all stop
gcware_services all restart
```
Services controlled by GCWare start/stop commands: `gcware`, `gcware_monit`, `gcware_mmonit`
**Example:**
- **Multi-Instance Server (2 GNodes):** `192.168.146.20 & 192.168.146.40`, with `192.168.146.20` being the composite node.
**Unified Start/Stop Commands for a Specific Type of Service:**
```sh
gcluster_services gcluster start/stop
gcluster_services gcware start/stop
gcluster_services gcrecover start/stop
gcluster_services syncserver start/stop
gcluster_services gbase start/stop
gcmonit.sh start/stop/status
```
**Example:**
```sh
[gbase@rhel73-1 ~]$ gcluster_services gbase stop
Stopping gbase: [OK]
Stopping gbase: [OK]
[gbase@rhel73-1 ~]$ gcmonit.sh stop
Stopping GCMonit success!
```
**Start/Stop Commands for a Single Instance in a Multi-Instance Server:**
Only GNode supports multiple instances, while GCWare and Coordinator can have only one instance per physical machine. Start/stop commands for GNode and SyncServer services:
```sh
gcluster_services syncserver_ip start/stop
gcluster_services gbase_ip start/stop
```
**Example:**
```sh
gcluster_services gbase_192.168.146.40 stop
gcluster_services syncserver_192.168.146.40 stop
```
**Connecting to a GNode Instance with `gncli` in a Multi-Instance Server:**
```sh
gncli –h ip
```
**Example:**
```sh
[gbase@rhel73-1 sys_tablespace]$ pwd
/opt/192.168.146.40/gnode/userdata/gbase/testdb/sys_tablespace
[gbase@rhel73-1 sys_tablespace]$ ls

## 2. Features Affected by Multi-Instance Deployment
Compared to versions V8.6 and V9.5.2, version V9.5.3 supports multi-instance deployment, affecting the following features:
- License acquisition and installation changes
- Node directory structure changes
- Cluster service management changes
- Cluster upgrade and rollback changes
- Cluster node replacement changes
- Cluster backup and recovery changes
- Compatibility issues between multi-instance and non-multi-instance versions—local load changes
### 2.1 Upgrade and Rollback
#### Single-instance to Multi-instance Upgrade
Steps: Upgrade → Expansion → Multi-instance NUMA Binding [Optional]
**Step 1: Upgrade**
The upgrade syntax remains unchanged. The original cluster to be upgraded must be version 952 or above.
```sh
./gcinstall.py --silent=demo.options -U
```
For cluster upgrades, `gcwareHost` must be specified and must be the old version gcware node. For cluster upgrades, `gcwareHostNodeID` cannot be specified if using IPv4; if not using IPv4, `gcwareHostNodeID` must be specified and its value must be the node ID of the existing gcware.
**Note:**
To find the `gcwareHostNodeID` for non-IPv4, check the `gcware.conf` file in the `gcware/config` directory. The `nodeid` under `Totem` is `gcwarehostnodeid`, and the `nodeid` under `gcware` is `coordinatehostnodeid`.
**Step 2: Expansion**
Execute with the database administrator user (e.g., gbase).
Install cluster software on the new multi-instance node:
```sh
./gcinstall.py --silent=demo.options --license_file=gbase.lic
```
Modify `demo.options`: add `dataHost`, fill in the existing `existCoordinateHost`, `existDataHost`, and `existGcwareHost`, and comment out `#coordinateHost`, `#coordinateHostNodeID`, `#gcwareHost`, and `#gcwareHostNodeID`.
Create distribution:
```sh
gcadmin distribution gcChangeInfo.xml p 1 d 1
```
Generate a new hashmap:
```sql
gbase> initnodedatamap;
```
Data redistribution:
Adjust the rebalance parameters as needed based on the data volume to be redistributed:
```sql
gbase> set global gcluster_rebalancing_concurrent_count=0;
gbase> rebalance instance;
gbase> set global gcluster_rebalancing_concurrent_count=3;
gbase> select * from gclusterdb.rebalancing_status;
```
Delete the old hashmap:
```sql
gbase> refreshnodedatamap drop 1;
```
Delete the old distribution:
```sh
gcadmin rmdistribution 1;
```
**Step 3: Multi-instance NUMA Binding [Optional]**
You can choose to bind the NUMA node based on actual needs. Refer to the NUMA binding section in the previous chapters. Modify the `gnode/server/bin/gcluster_services` file under the multi-instance and restart the cluster service.
**Note:**
Possible issues during the expansion step of a single-instance upgrade to a multi-instance version:
```sh
./gcinstall.py --silent=demo.options --license_file=20210323.lic
```
After execution, the multi-instance data node may not have a license file. Re-execute `./License` import, but if it still doesn't have the file, manually copy it and then start the gbase service.
#### Multi-instance to Multi-instance Upgrade
The upgrade syntax remains unchanged.
**Automatic Rollback**
Errors occurring during single-instance to multi-instance or multi-instance to multi-instance upgrades will automatically rollback without manual intervention.
**Manual Rollback**
The cluster must be available before rollback. Rollback syntax is as follows:
Switch to the `gcinstall` directory:
```sh
python Restore.py --silent=demo.options –backupFile= --backupGcwareFile=
```
**Note:**
If rolling back from multi-instance to single-instance, ensure no expansion or contraction operations were performed on the cluster after the upgrade. The upgrade program backs up important files of the original cluster before upgrading, such as system tables and environment variables; user data is not backed up. If the original cluster was multi-instance, the backup file will have a multi-instance identifier. The rollback program will automatically determine whether to rollback to single-instance or multi-instance by reading the backup file.
### 2.2 Node Replacement
There are three types of node replacement:
**Coordinator Node Replacement**
On a normally functioning management node, execute the following command:
```sh
replace.py --host=IP --type=coor --dbaUser=dba_user --dbaUserPwd=*** --generalDBUser=db_user --generalDBPwd='***' –overwrite --sync_coordi_metadata_timeout=minutes --retry_times=* --license_file=***
```
**Gnode Node Replacement**
On a normally functioning management node, execute the following command:
```sh
replace.py --host=IP --type=data --dbaUser=dba_user --dbaUserPwd=*** --vcname=vc_name --generalDBUser=db_user --generalDBPwd='***' –overwrite --sync_coordi_metadata_timeout=minutes --retry_times=* --license_file=***
```
**Gcware Node Replacement**
On a normally functioning gcware node, execute the following command:
```sh
cd $GCWARE_BASE/gcware_server/
./gcserver.py --host=IP --dbaUser=gbase --dbaPwd=gbase --overwrite
```
Coordinator and gnode node replacements are not affected by multi-instance; operations remain unchanged (including composite nodes of coordinator and gnode).
Gcware node replacement syntax after unbinding gcware is as follows:
Multi-instance gcware node replacement removes the `--prefix` parameter. `gcserver.py` reads environment variables to obtain the installation path of gcware. `gcserver.py` reinstalls the replaced gcware node, copies gcware data, and completes the gcware node replacement.
If gcware, gcluster, and gnode are deployed on the same server, it is recommended to replace the gcware node first, then the gcluster node, and finally the gnode node.
### 2.3 Backup and Recovery
Single-machine multi-instance backup and recovery `rcman` adds parameter `-s` to specify the backup instance's IP. If this parameter is not specified, the backup fails.
The current version supports backup and recovery for non-gbase database users. `gcrcman.py` and `rcman` add parameter `-U` to specify the database username for backup and recovery. This user needs to have access to all cluster tables. If the specified user lacks sufficient permissions, the program will error out and exit. If not specified, the default is the gbase user.
The current version supports backup and recovery of independently deployed gcware versions.
### 2.4 Impact and Solutions for Local Loading in Multi-instance
Multi-instance deployment impacts local file loading functionality, leading to compatibility issues compared to non-multi-instance versions. The local loading path syntax format in multi-instance uses the following format:
```sh
file://host + abs_path
```
**Note:** If the cluster is deployed as multi-instance, any original local loading path using the syntax `file://+abs_path` needs to be rewritten to use the specified host syntax format. | congcong |

#Let's talk semantics#HTML#WebDev#SEO
What are semantics in the first place?
_Semantic HTML tags clearly indicate the role of the content they enclose, such as header, article, footer, and aside. In contrast, non-semantic tags like <span> and <div> do not provide any contextual meaning on their own._
**<u>Why Semantics HTML?</u>**
_Semantic HTML makes code easier to read and understand. Even non-developers can understand code better when semantic tags are used. These tags help both search engines and assistive technologies understand the structure and meaning of web content._
**<u>Benefits:</u>**
- Accessibility: _Semantic tags make it easier for screen readers to interpret and navigate web content._
- SEO: _Semantic HTML helps search engines better understand and index web content._
**<u>The Role of Semantic HTML in Enhancing SEO and Web Accessibility</u>**
_Semantic HTML plays a crucial role in SEO by indicating the role of the content to search engines. Tags like header, article, nav, section, and footer help search engines determine the relevance of content to user queries._
<u>**Examples of Positive SEO Impact**</u>
- Case Study 1: _A blog using <article> tags sees improved rankings because search engines can easily identify the main content._
- Case Study 2: _An e-commerce site using <product> tags with schema markup achieves rich snippets in search results, leading to higher click-through rates._
<u>**How do semantic tags help search engines understand web content better?**</u>
_Semantic HTML enhances the compatibility of web content with assistive technologies, such as screen readers. Tags like nav, main, and footer enhance screen reader navigation. Semantic HTML promotes an inclusive web experience by improving keyboard navigation and understanding._
**<u>Examples</u>**
- Screen Reader Navigation -_Tags like article, section, and aside group related content together, providing context about the role of each content block._
- Landmarks-_Tags like header, nav, main, and footer create landmarks that screen readers can list, allowing users to jump directly to these parts of the page._
<u>**How does semantic HTML improve the accessibility of web pages for users with disabilities, including screen reader compatibility?**</u>
You might ask yourself how semantic HTML improves the accessibility of web pages with disabilities?
**<u>Inclusive Web Experience </u>**
Using semantic HTML promotes an inclusive web experience by:Using semantic HTML promotes an inclusive web experience by:
_- Keyboard Navigation:Keyboard inaccessibility is improved when using the semantic HTML since it has the structure and order of content that is easily understandable. This is especially important to all users who have mobility impairments using keyboard navigation.
- Enhanced Understanding:Semantic tags add context to structurally identified points which helps assistive technologies in providing a much smoother and more meaningful interpretation and use of the content. For example, figure tag with figcaption can tell image description to the listeners, so, users with visual impairments can also use those pages._
**<u>Examples of how using semantic HTML can positively impact a website’s SEO performance.</u>**
_- Improved Content Hierarchy and Readability - Semantic HTML provides a clear and logical structure to the content, making it easier for search engines to read and understand.
- Enhanced Rich Snippets and Structured Data - Semantic HTML tags work well with structured data, which can enhance the appearance of search results with rich snippets.
- Better Accessibility and User Experience - Semantic HTML improves the accessibility of web pages, leading to a better user experience, which can indirectly impact SEO._
<u>**Enhancing SEO with Semantic HTML**</u>
_- Compatibility with Assistive Technologies
Semantic HTML enhances the compatibility of web content with assistive technologies, such as screen readers
- Screen Reader Navigation
Screen reader tags including nav for grabbing navigation bars, main for grabbing the content that is most relevant to the page’s purpose, and footer for grabbing the content found at the bottom of the page enhance the efficiency of screen reader navigation through the web content. There are always options that allow users to access main content and/or other sections of the page.
- Labeling and Associations
In form controls, the elements such as label tag, and fieldset enable the proper labeling of the form control and grouping to facilitate the passing of this information by screen reader._
**<u>Conclusion </u>**
_Semantic HTML plays an important role both in increasing the website’s ranking and in making it more accessible for people with disabilities. Semantic tags organize web content in a way that is more comprehensible to search engines, thus improving the rating of webpage results, along with improving website accessibility for disabled civilians. Semantic HTML is one of the Web Development best practices that should be worked to achieve better results from the search engine’s point of view and an improved Web accessibility._

### 3.检查安装
要检查它是否已安装，请打开终端并运行:
```shell
magick --version
```
如果您看到类似下面的输出，那么您就代表安装好了！
```shell
Version: ImageMagick 7.1.1-34 Q16-HDRI aarch64 22301 https://imagemagick.org

Compiler: gcc (4.2)
```
## 二、基本命令
ImageMagick 拥有众多功能和能力。我将重点介绍我日常的使用一些功能,处理一些简单、实用的用例，但实际上，我们只是触及了此工具的表面。还有更多操作可以查看官方文档。
### 1.查看图片信息
在使用之前我们先了解一下检查图片信息的命令,使用 **magick identify** 检查你的图片信息。
```shell
magick identify tiger.jpg
```
输出
```shell
tiger.jpg JPEG 1280x853 1280x853+0+0 8-bit sRGB 279261B 0.000u 0:00.000
```
各个参数的代表的意义：
* tiger.webp:文件名。
* WEBP:图像格式（WEBP）。
* 1280x853:图像的维度，宽度为800像素，高度为400像素。
* 1280x853+0+0:图像维度和偏移量。
* 1280x853 表示图像的宽度和高度。
* +0+0 表示图像的偏移量（起始点位置），在这里表示没有偏移（从左上角开始）。
* 8-bit:每个颜色通道的位深度（这里是8位）。
* sRGB:图像的颜色空间（标准RGB颜色空间）。
* 279261B:图像文件的大小（字节），这里是279261字节（约279KB）。
* 0.000u:用户CPU时间（以秒为单位），即处理图像所花费的CPU时间。
* 0:00.000:真实时间（以分钟和秒为单位），即处理图像所花费的实际时间
### 2.转换图像格式
要将图像从一种格式转换为另一种格式，ImageMagick支持超过200种不同的图像格式，包括但不限于 PNG、JPEG、GIF、WebP、HEIC、SVG、PDF、DPX、EXR 和 TIFF 等。如果要转换图片格式,请使用命令 **magick**(以前版本是convert)后跟输入和输出文件名。例如，要将 PNG 图像转换为 WEBP，请运行：
```shell
magick input.png output.webp
```
同样，你想转换一个目录中的所有png 到webp,可以使用下面命令应用于目录中的所有图像：
```shell
mogrify -format webp *.png
```
这会将当前目录中的所有 PNG 文件转换为 WEBP,并保持原文件不变。
### 3.调整图像大小
要调整图像大小，请使用-resize 参数，后跟新尺寸。例如，要将图像大小调整为800x600像素，请运行：
```shell
magick input.jpg -resize 800x600 output.jpg
```
您还可以以百分比的方式来缩放图片：
```shell
magick input.jpg -resize 50% output.jpg
```
这会将图像大小调整为原始尺寸的 50％，通常，更改图像大小的最常见方法是将其缩小以适应所需大小。但是可以完全放大图像。
### 4.翻转和旋转
现在让我们看看如何翻转和旋转图像，这有时很有用。要旋转图像，请使用-rotate 参数。例如，要将图像顺时针旋转 60 度，请运行：
```shell
magick input.jpg -rotate 60 output.jpg
```
您还可以将旋转角度指定为负值以逆时针旋转：
```shell
magick input.jpg -rotate -60 output.jpg
```
### 5.裁剪图像
要裁剪图像，请使用-crop选项的命令，后跟新尺寸。裁剪的原点在左上角,例如，要从左上角开始将图像裁剪为 400x400 像素，请运行：
```shell
magick input.jpg -crop 400x400+0+0 output.jpg
```
该400x400部分指定新的尺寸，+0+0指定裁剪的起点。
您还可以将起点指定为图像大小的百分比：
```shell
magick input.jpg -crop 50%x50%+0+0 output.jpg
```
这会从图像的左上角开始将图像裁剪为原始尺寸的 50％。
### 5.添加水印
要给图片添加水印,使用下面类似下面的命令,例如在右下角添加一个“blog.eimoon.com”的水印。
```shell
magick image.jpg -gravity SouthEast -pointsize 24 -fill white -annotate +10+10 "blog.eimoon.com" image_watermarked.jpg
```
下面解释一下每个参数的含义：
* **magick**: ImageMagick的命令行工具，用于图像转换和处理。
* **image.jpg**: 输入的图片文件。
* **-gravity SouthEast**: 将水印定位在图片的右下角（东南角）。
* **-pointsize 24**: 设置水印文字的大小为24点。
* **-fill white**: 设置水印文字的颜色为白色。
* **-annotate +10+10 "blog.eimoon.com"**: 在指定位置添加水印文本。+10+10 表示将水印文字从右下角向左上方偏移10像素，以免贴边太近。
* **image_watermarked.jpg**: 输出的图片文件，带有水印。
*
您可以调整不透明度和重力值，将水印放置在您喜欢的任何位置。您还可以为图片添加更多效果。尝试不同的选项，看看您能想出什么样的创意效果.
### 6.添加模糊效果
要为图像添加模糊效果，使用-blur参数，后跟半径和 sigma 值。sigma 值决定模糊量。要添加半径和 sigma 值为 5 的高斯模糊，请运行：
```shell
magick tiger.jpg -blur 5X5 tiger2.jpg
```
### 7.添加锐化效果
要为图像添加锐化效果，请使用-sharpen选项的命令，后跟半径和 sigma。要添加半径为 0 且 sigma 为 1 的锐化效果，请运行：
```shell
magick tiger.jpg -sharpen 0X1 tiger2.jpg
```
您可以调整半径和 sigma 值来创建不同级别的锐化.
## 结论
在本文中，我们介绍了 ImageMagick 提供的通过命令行处理图像的一些基本功能。还有一下颜色修改,生成gif动画,添加边框等等操作, 我使用的不多,如果你感兴趣的可以查看[文档](https://imagemagick.org/Usage/)。
当然，再次强调,我们这些操作只触及了冰山一角，还有许多高级功能和选项可用,因此请务必查看ImageMagick 文档以了解更多详细信息。

1,917,117 | Time Management Hacks for the Overwhelmed Tech Student | Time management is the scourge of our progress and output. It affects us in work, life, and school.... | 0 | 2024-07-09T10:05:57 | https://dev.to/martinbaun/time-management-hacks-for-the-overwhelmed-tech-student-183m | beginners, productivity, learning, softwaredevelopment | Time management is the scourge of our progress and output. It affects us in work, life, and school.
These are tips to help you manage your time as a tech student.
## Habit stacking
Habit stacking is an underrated hack that students rarely use. It is a skill I subconsciously use to boost my productivity in my daily endeavors. It allows you to handle multiple things at the same time. It is a timesaver that is so simple to implement and stick to. One of my favorite habit stacks is having coffee as I handle deadlines and administrative duties for my remote team. I enjoy my morning coffee and log into meetings with my remote team with a big smile. Another example of habit stacking I do is writing my YouTube video scripts while enjoying my break from the hustle of my work.
The principle of habit stacking is placing symbiotic tasks together, allowing you to multitask efficiently. You can use this principle in various ways as a student. I would practice coding before bed, or study a specific short topic on my coffee break. You'll knock down two birds with one stone doing this. You'll notice your time management and productivity steadily improve. Habit stacking is a game changer that will help you stay focused. It has been a great addition to my routine and will improve your time management. I have written an article to help you build on habit stacking.
Read: *[Action Breeds Clarity](https://martinbaun.com/blog/posts/action-breeds-clarity-2/)*
## Time blocking
Time blocking is a core time management hack I live by. It is a simple and efficient way to manage time, prioritize tasks, and prevent procrastination. It forces you to be accountable for how you spend your time. It also reveals bad habits we have. It's no secret we tend to extend our breaks or push our work back to do other things. This is the worst productivity killer as we unconsciously train ourselves to put off vital tasks for pleasurable activities. I've seen people become overwhelmed with their workload because they didn't properly manage their tasks.
I like to focus on one task at a time. I have to-do lists for each day and week that I adequately distribute in specific time blocks. I focus on one task and do it to the best of my ability. I don't give myself the leeway to spend too much time on a task. These time blocks force me to use my time efficiently. I pair this hack with time tracking to ensure I use my time properly. I've incorporated checklists into this strategy. They detail the important aspects of the project that require my attention. Checklists are a good way to increase productivity. They guide your work and ensure you don't waste your time.
You can make a to-do list with a checklist breaking down what to do. Students feel stressed when they have to balance numerous subjects. You can make this simple. Allocate time to your studies, have each topic with its delegated time slot, and watch your workflow improve. You can also get software to help you manage your time. I use Goleko in addition to checklists to handle all my tasks and responsibilities. It helps me [Manage Projects Better.](https://goleko.com/) You can learn more about checklists in the article below.
Read: *[Boost Productivity With Checklist](https://martinbaun.com/blog/posts/boost-productivity-with-checklist/)*
## The Pareto Principle (80⁄20 Rule)
The Pareto principle is a favorite of mine. It challenges you to decipher which tasks produce the best results. Doing these tasks first tends to produce the best outcome. I like working on developing software and offering services to my clients. These are 20% of tasks that produce 80% of the results. You can divide these tasks based on their importance. Break these tasks into smaller sections. Checklists are excellent for this purpose. This helps you focus and stay on track with the set goals.
These tasks are usually academic for students. You can pick the topic with the highest return. This is your 20%. Then divide the topic into specific objectives. A study guide is perfect for this. You can refer to previous academic year assessments to gauge the high-yield areas. You can use your study sessions to hammer the content and decipher areas that need to improve. You can take this further by forming study groups. This will help you cover more as everyone is assigned a topic to teach and explain. You can do this for any critical task to produce the best results. You'll be able to accomplish your goals and enhance your productivity.
The Pareto principle allows for good time management. It helps you stay organized with a healthy work-life balance. It will help you handle simple tasks, reduce mental fatigue, and decrease stress. You can improve time management on your group projects by using screen recording software to give feedback. You can improve time spent on back-and-forth by giving excellent feedback on specific tasks. VideoFeedbackr is an excellent choice for your needs. [Give feedback hassle-free](https://videofeedbackr.com/) while saving your valuable time.
## Eliminate Distractions
You can plan your day with a manageable amount of tasks. We overestimate our capabilities and end up frustrated when things don't work. Task management is a key principle to follow. Prioritize your tasks giving them different levels of importance and urgency. Saying you'll study for 10 hours is a lie. You'll probably procrastinate for 5 hours simply trying to start anything. This stunts your academic and professional life. It also grossly inflates the time you spend on tasks.
It is better to set realistic and achievable goals. You can plan to study for 6 hours. You can divide these 6 hours into three 2-hour blocks. This will give you a better chance to study. Doing it this way also gives you reasonable rest times. These are vital for stress reduction and management. You can use productivity apps if they help you stay focused. Enhanced productivity is achievable by using your time well and proper project management. College can be a stressful place without effective time management techniques. I find using interesting documents helps me focus more. This is why I use ElegantDoc for all of my softcopy needs. It lets me [Make Impactful Documents in Seconds](https://elegantdoc.com/) allowing me to have fun and keep my focus as well.
Distractions are everywhere and it's vital to keep yourself focused. Accomplishing goals is addictive. You can finish one thing at a time daily or weekly. This will help you keep track of your progress. It will help you reduce stress and give you enough time for adequate sleep. Good time management skills are the key to seeing this type of success.
## The Starting Principle
The starting principle deciphers whether a task is pursuable in your current mental state. It is excellent for tasks you loathe or aren't looking forward to. I have used it to great effect and seen great results from it. You give yourself 5 minutes to work on that task. You can then determine whether you want to continue or not. I stop doing it if my view on it hasn't changed. This is one of my best time management tips. It prevents you from spending time forcing yourself to do a task. I prioritize quality in everything I do. Forcing yourself to do a task you don't want to do is counterproductive. You'll take regular breaks and get easily distracted.
Many people find themselves powering through a task to meet upcoming deadlines. This is the wrong approach to follow when striving for excellence. You can refer to your long-term goals as often as you can. They will help formulate practical tips to keep you focused and on track. Forcing yourself to do a task for the sake of it is detrimental to your well-being and reduces your productivity.

1,917,123 | Common Terms in Computer Vision | When you read about Artificial Intelligence, Machine Learning and Computer Vision you often come... | 0 | 2024-07-09T10:14:42 | https://dev.to/askui/common-terms-in-computer-vision-36o8 | javascript, typescript, tutorial | When you read about Artificial Intelligence, Machine Learning and Computer Vision you often come across terms that seem to be common.
But do you know all of them and what they actually mean?
In this blog we will list the most common terms that we use in our day-to-day work.
## Bounding Box
A _Bounding Box_ is a rectangle around a detected element or region in a picture. In code they are represented with their coordinates. There are different formats used. Some examples:
* `pascal_voc`: \[xmin, ymin, ymax, ymax]
* `coco`: \[xmin, ymin, width, height]
* `yolo`: normalized \[xcenter, ycenter, width, height]
Example in JSON:
```json
{
"xmin": "1128.2720982142857",
"ymin": "160.21332310267857",
"xmax": "1178.8204241071428",
"ymax": "180.83512834821428"
}
```
## Annotation
An annotation can be the visual representation of a bounding box or just a keypoint. But also a textual description is possible.
Usually bounding boxes are used in _grounding_ together with _labels_ and to establish a ground-truth or reference for trainingdata and testdata for training computer vision models.
Annotations differ from labels in that they can include any additional metadata.
## Label
A label is given to a bounding box or a keypoint and identifies which class or category an object or area the model assigned to it. In the above example the `person`-text above the bounding box is a label.
Labels are also used to train models where the training set consists of correctly labeled images.
## Image Classification
Image classification is used to put a predefined label on an image.
For an image of a cat would get the label _cat_, while the image of a sunset would get the label _sunset_.
This seems like a trivial thing to do but it actually has a lot of practical use cases:
* Recognition of objects or entities depicted in images
* Classifying medical image for detecting abnormalities
* Image retrieval based on categories
## Image Segmentation
The goal of image segmentation is to divide an image into areas that belong together. The areas are visually distinctive from each other.
The output of the process is a set of segmentation masks that can be used to process the image further.
Take this segmentation of an avatar image where the masks define where a person is and where the background is. A practical application would be to remove the background based on these masks.
## Object Detection
Object detection is used to identify objects in images and video. It is a crucial task in a lot of domains such as Surveillance and Security, Environmental Monitoring and Augmented Reality.
It takes visual input and determines the objects that are present. The objects are described with a bounding box and also get a class-label and sometimes a confidence score.
## Feature
A distinctive feature in an area or keypoint of an image. Usually you attribute features to a specific class you want to detect.
For a **mouse** those could be the shape, surroundings or fur pattern. Those are represented as numerical vectors, called descriptors, that capture the visual properties of an area or keypoint.
## Feature Vector
Feature vectors are not limited to Computer Vision, but used there for all kind of tasks.
A feature vector is generated from input data such as an image and contains one numerical entry for every feature. Feature vectors are typically high-dimensional.
In practice feature vectors get generated by a _Backbone_ (see next heading) which are by themselves models trained to extract useful features.
## Grounding
_Grounding_ is the process of connecting high-level concepts, for example **Mouse**, with visual features, for example **tail**.
Now that you have high-level concepts and their representation in the model you can also put them into context and relation with each-other.
Grounding can also be done by humans for training data. There you annotate an input with bounding boxes and labels, so the model has a _Ground Truth_ to learn from.
## Referring Expression
Referring Expression in Computer Vision are used to describe objects or areas in images. They can contain attributes like color or relations to other objects.
Take this example: "The bike next to the child." You do not point to the bike directly but give a reference point _child_. Or you could give a description: "The red building next to the blue car.".
Referring Expressions are typically used in tasks like object localization, object detection or image retrieval.
## Zero-Shot
In general _zero-shot_ is when models can do tasks they were not specifically trained on.
To some extend, and most of them rather poorly, every model can perform tasks without specific training as the goal of training is to get a higher-level understanding of concepts.
_Zero-shot_ learning in Computer Vision also includes more information than just labeled examples. The focus is on data that describes relationships between categories, so the model can generalize better to new categories.
This also requires large scale training on a lot of data, so the model is exposed to billions of examples and can generalize without specific training to new tasks.
## Conclusion
That are all, but sure there are more. Do you know of any we should include?

The community straight away came together and formed their collective groups to make sure their community members don't get left behind. There were many events including workshops, meetups, bookclubs happening around the world as this news broke.
Women Who Code Dublin (ex-director here 🙋🏻♀️) and Women Who Code Belfast (who has been very active) banded together to form [Women Coders Community Ireland](https://www.meetup.com/women-coders-comm-ireland/) -- this is an all-island group. If you are interested in getting involved, let us know.
One core ex-WWC group of folks created Women Coders Network, they are re-creating the various structure for keeping community events going, and are still lookin for volunteers. You can join their discord server. 👇👇👇
{% embed https://discord.gg/YpaJ3JckNM %}
And today's news broke of yet [another long-running organisation that will be shutting down, and that's Girls in Tech](https://x.com/GirlsinTech/status/1810355749148586416)!
And it all boils down to funding as it's been harder to get funding from companies and people alike the last few years.
I am involved in initiatives that advocate diversity in tech, but right now it's primary focus is Ireland and Northern Ireland. I thought in isolation it was me who thought getting funding was hard. The most basic is getting support for meetups - that's a little bit "easier" with companies offering to host (and cater food which is a bonus as that's not cheap).
But what about the wider implications, like community conferences (which I have had chats with a few) that found it hard to seek sponsors to help alleviate the expenses of running the event and offering affordable tickets.
Free events (local community meetups) are still expected to provide food and beverage with 40-60% no-shows by attendees.
Many of this is taken for granted by everyone. What can we all do to help initiatives that are still running. And of course, my ones as when I heard about Women Who Code, I thought "If they can't do it, how can [Coding Grace](https://codinggrace.com) survive?" and the spiralling starts. The difference with [PyLadies Dublin](https://dublin.pyladies.com/) (I run monthly, if possible) is that it's part of [PyLadies](https://pyladies.com/) global and is supported by [The PSF](https://www.python.org/psf-landing/).
{% embed https://x.com/pyladies/status/1792164972149026826 %}
This year, PyLadies Auctions (annual event at [PyConUS](https://us.pycon.org/2024/)) raised over US$60k this year! So I can apply for support (which I rarely do and rely on local support). The meetup page for PyLadies Dublin is part of PSF's pro-network account on meetup, so no need to pay meetup (extortionate) fees.
Locally, we don't have that privilege, I keep an eye out on local funding like [Funding Point from The Wheel](https://www.wheel.ie/funding), but the ones of interest only allows registered charities. 😢 Plus I don't have time to write applications to grants (and I'm not great at writing them either).
With [Coding Grace](https://codinggrace.com) (an organisation I co-founded), it's a registered not-for-profit Irish company (CLG) which has its minimum annual expenses - bank and accountant's fee are the main ones.
I am very bad at asking for donations of which we have several ways from Open Collective (it's down to 2 people who regularly contributes) to Patreon, Ko-Fi and even GitHub sponsors.
Can someone help me figure out how to ask for donations without feeling guilty?
What about support for other exisiting organisations out there? Here's a list of curated groups around Ireland and Northern Ireland (this needs updating btw, so help would be appreciated here also), I don't know what the funding sitch is for all the groups that I'm not involved in, but if there are ones that you are interested in, even if you can't support with your time, find a way to donate.
https://diversityintech.fyi/diversity/
Murmers of decreasing budgets allocated to DEI/CSR initiatives in the corporate world, how can we make sure that it's still very important?
I've no answers, I am feeling despair although this means we as a community have to work even harder. I hope to kickstart and figure out the next steps at the very least for Coding Grace with the rest of the team and our amazing advisors/mentors. Find a smarter way to keep what we doing alive and get funded.

1,917,130 | How to List and Print All Layers in PyTorch Model | Introduction In PyTorch, a well-liked tool for deep learning, you might find yourself... | 0 | 2024-07-09T10:19:15 | https://dev.to/novita_ai/how-to-list-and-print-all-layers-in-pytorch-model-8m3 | ## Introduction
In PyTorch, a well-liked tool for deep learning, you might find yourself needing to see and list every layer of your model. This is pretty handy when you’re trying to get how the model is put together, looking at its parts, or working with certain layers directly. This blog post will walk through three different ways you can go about listing and showing all the layers in your pytorch model. Moreover, this blog is going to introduce an excellent way for you to run Pytorch — on a GPU Cloud.
## Understanding PyTorch Models
Inside a pytorch model, there are different layers that each do their own thing to the data they get. These layers work together to shape up what’s known as the architecture of your model. During training time, certain values within these layers adjust themselves — these are called trainable parameters — aiming to make your model smarter over time.
### The Basics of PyTorch Model Architecture
In PyTorch, when you’re setting up a model, what you do is extend the nn.Module class to create your own structure. Inside this setup, there's a must-have method called forward. This one is crucial because it takes in your data and then marches it through the layers of your model one by one until it spits out the result. Think of each layer as its own little worker, like nn.Linear for straight-up connections or nn.Conv2d for filtering images.
To make sure these workers line up correctly and pass things along in order, we use something called the nn.Sequential class. With this handy tool, all you have to do is list out your layers in order they should work on the data. It’s like telling them: "You first! Now you go!" And so on until every piece has done its job.
### Key Components of PyTorch Models
In PyTorch, there are a few important parts that really matter. For starters, we’ve got what’s called a pretrained model. This is basically a ready-to-go model that has already learned a lot from being trained on tons of data. It knows certain things because it remembers the weights and biases from its training time. When we use one of these pretrained models, we’re taking all that knowledge it picked up and applying it to whatever task we have at hand.
## Setting Up Your Environment for PyTorch
Before diving into the cool stuff we’re going to talk about later in this blog, you’ve got to get your computer ready. This means putting a few things on it like Python, PyTorch, and torchvision.
First off, Python is what you’ll be using when you do deep learning with PyTorch. Make sure it’s set up on your computer. If not, head over to the official Python website where you can grab and install it.
After that comes installing PyTorch itself. It’s basically the star of the show for deep learning in PyTorch land. It gives you all sorts of tools and goodies for making and teaching neural networks how to learn stuff by themselves. To get it onto your system, just use pip package manager with `pip install torch`.
But wait — there’s more! You also need torchvision in your toolkit because if working with images is what excites you then this library has got some treats for ya’. Think pre-made datasets or models which are super handy for vision tasks plus ways to tweak those images so they’re just right for training purposes; again pip makes life easy here: `pip install torchvision`.
### Installing PyTorch
To get PyTorch on your computer, just open up where you type commands (like the terminal or command prompt) and put in:
```
pip install torch
```
This tells your computer to grab the newest version of PyTorch and set it up for you. You’ll need a good internet connection because this might take a bit of time.
### Verifying PyTorch Installation
To make sure PyTorch is set up right, you can try out a basic Python script or use it in an interactive setting like Jupyter Notebook or the Python REPL. Just go into the Python environment you like best and bring in the torch module with this line of code:
```
import torch
```
## Listing Layers in a PyTorch Model
Now that we’ve got the basics down about how a PyTorch model is put together, let’s dive into how we can see and list every layer it has.
### Using .children() and .modules() Methods
To show every layer in a pytorch model, we can use the `.children()` and `.modules() `methods together with dot notation. Here's how you do it:
```
for name, module in model.named_modules():
print(name, module)
```
With this code snippet above, we’re using the `named_modules()` method to get each part of our PyTorch model along with its name. By going through these one by one and showing their names and what they are, we manage to display all parts of our PyTorch setup.
What comes out from running this bit of Python is a list that tells us the names of different layers and shows us their modules too. This info is pretty handy for when you want to dive deeper into certain layers or change them up somehow.
### Practical Examples of Listing Layers
When working with a PyTorch model, it’s really handy to know how to show and list all its parts. This can help you understand the model better, tweak certain bits of it, or fix issues. Here are some easy ways to do that:
- To get straight to a specific part using its name:
- You just use dot notation like this: `model.layer1.0.relu`
- When you want to go through each part one by one and maybe change things as you go:
- A simple for loop lets you walk through named modules so you can work on them individually.
- If your goal is just seeing what parts there are along with their details:
- Combining the `named_modules()` method with `print` gives you both names and info about each module.
## Printing Layers Details
Besides just naming the different parts of a PyTorch model, you might also want to share more about each part. This includes how many settings it has and what its results look like.
### Accessing Specific Layer Information
If you’re diving into a PyTorch model and want to peek at the details of its layers, there’s a handy tool called “named_parameters” that can help. This function is like a treasure map; it guides you through all the named parameters in your model. By using this map, you can find specific information about each layer.
Here’s how it works: with just a few lines of code, you can print out everything about each layer.
```
for name, parameter in model.named_parameters():
print(name, parameter)
```
In these lines of code, `name` tells us which layer we're looking at while `parameter` shows us the tensor for that layer. It's like getting an X-ray view of your pytorch model - seeing what makes up each part without having to cut anything open!
On top of that, if you’re feeling adventurous or need something more user-friendly for complex tasks or deep analysis on those layers? Check out the `ptrblck` library. It’s designed specifically for working smoothly with tensors and parameters in PyTorch models making things easier when dealing with complicated structures or needing detailed insights into how everything fits together.
### Custom Functions to Print Layers
If you want to see certain layers or groups of them in a PyTorch model, you can whip up your own functions with the help of PyTorch and Python. These bits of code will need your model as an input and then they’ll show you just the layers you’re curious about.
Take this for instance: if you’re interested in checking out all the convolutional layers a model has, here’s how you could do it:
```
def print_conv_layers(model):
for name, module in model.named_modules():
if isinstance(module, nn.Conv2d):
print(name, module)
```
With this function, we go through each named module within our pytorch model and check whether it’s a `nn.Conv2d` type. If that checks out, we get to see both its name and what’s inside.
## Advanced Techniques
Besides the simple ways of looking at and printing parts of a PyTorch model, there are some cooler tricks you can do for a deeper dive.
### Iterating Through Named Modules
When you’re working with a PyTorch model, going through named modules one by one lets you do certain things to each part. You can use the `named_modules` function for this. It gives you an iterator that goes over every named module in your model.
With this approach, getting into and changing specific parts of the model becomes possible. For instance, if there’s a particular layer you want to tweak or check out its output for more analysis.
A handy way to keep track of these modules is by putting them into a dictionary. This makes it super easy to find and work on any module just by knowing its name. Here’s how it looks:
```
named_modules_dict = dict(model.named_modules())
conv1 = named_module_dict['conv1']
```
In the example above, `conv1` points to the module called 'conv1'. Now that you've got hold of it directly from your list, doing whatever operation needed on it becomes straightforward.
### Using Hooks to Extract Layers’ Output
In PyTorch, hooks let you set up special functions that get called at certain times when your model is running. Think of it like setting a checkpoint in a video game where something specific happens. These are really handy if you want to see what’s going on inside certain parts of your model.
To make these work, first off, you’ve got to write a function. This isn’t just any function though; it needs four pieces: module, input, output, and context. The most important bit here is the ‘output’ part because this lets you peek into what the layer’s spitting out and change things around if needed.
Here’s how you can whip up one of these hook functions:
```
def hook_fn(module,input,output):
# Do whatever with the output
print(output)
```
After crafting your function, attaching it to a layer in your model comes next. You do this by calling `register_forward_hook` on whichever layer catches your fancy:
```
layer.register_forward_hook(hook_fn)
```
With everything set up now whenever that particular piece of code runs during the forward pass — bam! Your little custom function jumps into action letting you mess with or simply observe the outputs right then and there.

## Introduction
Welcome, Flutter fans, to the world of "BBB - Ba Ba Bank" - the most imaginary bank you'll ever code for! 🐑💰
Disclaimer: This is a work of fiction. Any resemblance to actual banks, solvent or bankrupt, is purely coincidental. All banking functions depicted are used solely for educational purposes in learning Flutter and Dart design patterns. No real money was lost or gained in the making of this guide.
Imagine you're tasked with creating a mobile app for this quirky bank. Your mission: build an app that's strong, can grow, and is easy to fix. It should handle everything from counting sheep (not coins) to giving wool-based credit scores. As we go on this fluffy journey, we'll face challenges that we can solve with design patterns - the handy tools in a developer's toolbox.
Design patterns are like cooking recipes, but for coding. They help solve common problems that pop up in programming. By learning these patterns, we can write code that's faster, more flexible, and easier to manage than a well-behaved sheep.
In this guide, we'll see how to use different design patterns as we build our "Ba Ba Bank" app. We'll look at four main types of patterns:
1. Creational Patterns: These help us make new things in our code, like minting new sheep... I mean, coins.
2. Structural Patterns: These help us organize our code, like herding sheep into pens.
3. Behavioral Patterns: These help different parts of our code work together, making sure our sheep (code parts) play nice.
4. Architectural Patterns: These give our whole app structure, like planning the fanciest sheep barn ever.
So, grab your coding tools, put on your developer hat, and let's explore Flutter design patterns with "Ba Ba Bank"! Remember, in this made-up bank, the only real thing we're saving is knowledge. Let's make it grow! 🚀🐑💻
## Creational Patterns
Creational patterns focus on object creation mechanisms, trying to create objects in a manner suitable to the situation. As we start developing "Ba Ba Bank", we'll encounter several scenarios where these patterns prove invaluable.
### Factory Method
As we begin implementing the account creation system for "Ba Ba Bank", we realize that we need a flexible way to create different types of bank accounts. We anticipate supporting various account types such as savings accounts, checking accounts, and possibly investment accounts in the future. This is where the Factory Method pattern comes in handy.
The Factory Method pattern provides an interface for creating objects in a superclass, allowing subclasses to alter the type of objects that will be created. This pattern is particularly useful for our bank account creation system because it allows us to add new account types in the future without modifying existing code.
Let's implement the Factory Method pattern for our bank account creation:
```dart
abstract class BankAccount {
String accountNumber;
double balance;
BankAccount(this.accountNumber, this.balance);
void deposit(double amount);
bool withdraw(double amount);
double getBalance();
}
class SavingsAccount extends BankAccount {
double interestRate;
SavingsAccount(String accountNumber, double balance, this.interestRate)
: super(accountNumber, balance);
@override
void deposit(double amount) {
balance += amount;
balance += amount * interestRate; // Apply interest on deposit
}
@override
bool withdraw(double amount) {
if (balance >= amount) {
balance -= amount;
return true;
}
return false;
}
@override
double getBalance() => balance;
}
class CheckingAccount extends BankAccount {
double overdraftLimit;
CheckingAccount(String accountNumber, double balance, this.overdraftLimit)
: super(accountNumber, balance);
@override
void deposit(double amount) {
balance += amount;
}
@override
bool withdraw(double amount) {
if (balance + overdraftLimit >= amount) {
balance -= amount;
return true;
}
return false;
}
@override
double getBalance() => balance;
}
abstract class BankAccountFactory {
BankAccount createAccount(String accountNumber, double initialBalance);
}
class SavingsAccountFactory implements BankAccountFactory {
final double interestRate;
SavingsAccountFactory(this.interestRate);
@override
BankAccount createAccount(String accountNumber, double initialBalance) {
return SavingsAccount(accountNumber, initialBalance, interestRate);
}
}
class CheckingAccountFactory implements BankAccountFactory {
final double overdraftLimit;
CheckingAccountFactory(this.overdraftLimit);
@override
BankAccount createAccount(String accountNumber, double initialBalance) {
return CheckingAccount(accountNumber, initialBalance, overdraftLimit);
}
}
// Usage
void main() {
BankAccountFactory savingsFactory = SavingsAccountFactory(0.05);
BankAccountFactory checkingFactory = CheckingAccountFactory(1000);
BankAccount savingsAccount = savingsFactory.createAccount('SAV001', 1000);
BankAccount checkingAccount = checkingFactory.createAccount('CHK001', 500);
savingsAccount.deposit(100);
print('Savings account balance: ${savingsAccount.getBalance()}');
checkingAccount.withdraw(600);
print('Checking account balance: ${checkingAccount.getBalance()}');
}
```
By using the Factory Method pattern, we've created a flexible system for creating bank accounts. If we need to add a new type of account in the future, we can simply create a new class that extends BankAccount and a corresponding factory class. This approach adheres to the Open-Closed Principle, allowing us to extend our system without modifying existing code.
### Abstract Factory
As "Ba Ba Bank" expands its services, we decide to offer different types of banking products, each with its own set of accounts and cards. For example, we might have a "Standard Banking" package and a "Premium Banking" package. This is where the Abstract Factory pattern becomes useful.
The Abstract Factory pattern provides an interface for creating families of related or dependent objects without specifying their concrete classes. Let's implement this pattern for our banking packages:
```dart
abstract class BankAccount {
String getAccountDetails();
}
abstract class CreditCard {
String getCardDetails();
}
class StandardBankAccount implements BankAccount {
@override
String getAccountDetails() => "Standard Bank Account";
}
class PremiumBankAccount implements BankAccount {
@override
String getAccountDetails() => "Premium Bank Account";
}
class StandardCreditCard implements CreditCard {
@override
String getCardDetails() => "Standard Credit Card";
}
class PremiumCreditCard implements CreditCard {
@override
String getCardDetails() => "Premium Credit Card";
}
abstract class BankingFactory {
BankAccount createBankAccount();
CreditCard createCreditCard();
}
class StandardBankingFactory implements BankingFactory {
@override
BankAccount createBankAccount() => StandardBankAccount();
@override
CreditCard createCreditCard() => StandardCreditCard();
}
class PremiumBankingFactory implements BankingFactory {
@override
BankAccount createBankAccount() => PremiumBankAccount();
@override
CreditCard createCreditCard() => PremiumCreditCard();
}
// Usage
void main() {
BankingFactory standardFactory = StandardBankingFactory();
BankingFactory premiumFactory = PremiumBankingFactory();
BankAccount standardAccount = standardFactory.createBankAccount();
CreditCard standardCard = standardFactory.createCreditCard();
BankAccount premiumAccount = premiumFactory.createBankAccount();
CreditCard premiumCard = premiumFactory.createCreditCard();
print(standardAccount.getAccountDetails()); // Output: Standard Bank Account
print(standardCard.getCardDetails()); // Output: Standard Credit Card
print(premiumAccount.getAccountDetails()); // Output: Premium Bank Account
print(premiumCard.getCardDetails()); // Output: Premium Credit Card
}
```
The Abstract Factory pattern allows us to create families of related objects (in this case, banking products) without specifying their concrete classes. This makes it easy to introduce new types of banking packages in the future without modifying existing code.
### Builder
As we continue developing "Ba Ba Bank", we realize that we need to generate complex financial reports. These reports might have different combinations of information depending on the user's needs or their account type. This is where the Builder pattern comes in handy.
The Builder pattern separates the construction of a complex object from its representation, allowing the same construction process to create various representations. Let's implement a financial report builder:
```dart
class FinancialReport {
String? accountSummary;
String? transactionHistory;
String? creditScore;
String? investmentOverview;
String generateReport() {
StringBuffer report = StringBuffer();
if (accountSummary != null) report.writeln('Account Summary: $accountSummary');
if (transactionHistory != null) report.writeln('Transaction History: $transactionHistory');
if (creditScore != null) report.writeln('Credit Score: $creditScore');
if (investmentOverview != null) report.writeln('Investment Overview: $investmentOverview');
return report.toString();
}
}
class FinancialReportBuilder {
final FinancialReport _report = FinancialReport();
FinancialReportBuilder setAccountSummary(String summary) {
_report.accountSummary = summary;
return this;
}
FinancialReportBuilder setTransactionHistory(String history) {
_report.transactionHistory = history;
return this;
}
FinancialReportBuilder setCreditScore(String score) {
_report.creditScore = score;
return this;
}
FinancialReportBuilder setInvestmentOverview(String overview) {
_report.investmentOverview = overview;
return this;
}
FinancialReport build() {
return _report;
}
}
// Usage
void main() {
var standardReport = FinancialReportBuilder()
.setAccountSummary('Balance: $5000')
.setTransactionHistory('10 transactions in the last month')
.build();
var premiumReport = FinancialReportBuilder()
.setAccountSummary('Total balance: $50000')
.setTransactionHistory('30 transactions in the last month')
.setCreditScore('Excellent (800)')
.setInvestmentOverview('Stocks: 60%, Bonds: 30%, Cash: 10%')
.build();
print('Standard Report:\n${standardReport.generateReport()}');
print('\nPremium Report:\n${premiumReport.generateReport()}');
}
```
The Builder pattern allows us to create different types of financial reports with varying levels of detail without cluttering the FinancialReport class with numerous constructor parameters. This makes our code more readable and flexible, as we can easily add new report elements in the future.
### Singleton
As we develop the user authentication system for "Ba Ba Bank", we realize that we need a way to manage the user's session across the entire application. We want to ensure that there's only one instance of the user session, accessible from anywhere in the app. This is a perfect use case for the Singleton pattern.
The Singleton pattern ensures a class has only one instance and provides a global point of access to it. Let's implement a UserSession class using the Singleton pattern:
```dart
class UserSession {
static final UserSession _instance = UserSession._internal();
factory UserSession() {
return _instance;
}
UserSession._internal();
String? _token;
String? _userId;
void login(String token, String userId) {
_token = token;
_userId = userId;
}
void logout() {
_token = null;
_userId = null;
}
bool get isLoggedIn => _token != null;
String? get userId => _userId;
String? getToken() {
if (_token == null) {
throw Exception('User is not logged in');
}
return _token;
}
}
// Usage
void main() {
final session1 = UserSession();
final session2 = UserSession();
print(session1 == session2); // Output: true
session1.login('abc123', 'user001');
print(session2.isLoggedIn); // Output: true
print(session2.userId); // Output: user001
session2.logout();
print(session1.isLoggedIn); // Output: false
}
```
By using the Singleton pattern for UserSession, we ensure that there's only one instance of the session throughout the app. This prevents inconsistencies that could arise from having multiple session objects and provides a centralized point for managing the user's authentication state.
### Prototype
In "Ba Ba Bank", we might want to create templates for common types of transactions or account settings. The Prototype pattern can be useful in this scenario, allowing us to clone existing objects instead of creating new ones from scratch.
The Prototype pattern specifies the kinds of objects to create using a prototypical instance, and create new objects by copying this prototype. Let's implement a prototype for transaction templates:
```dart
abstract class TransactionTemplate {
String description;
double amount;
TransactionTemplate(this.description, this.amount);
TransactionTemplate clone();
}
class PaymentTemplate extends TransactionTemplate {
String recipient;
PaymentTemplate(String description, double amount, this.recipient)
: super(description, amount);
@override
PaymentTemplate clone() {
return PaymentTemplate(description, amount, recipient);
}
}
class TransferTemplate extends TransactionTemplate {
String fromAccount;
String toAccount;
TransferTemplate(String description, double amount, this.fromAccount, this.toAccount)
: super(description, amount);
@override
TransferTemplate clone() {
return TransferTemplate(description, amount, fromAccount, toAccount);
}
}
// Usage
void main() {
var rentPayment = PaymentTemplate('Monthly Rent', 1000, 'Landlord');
var rentPaymentCopy = rentPayment.clone();
rentPaymentCopy.amount = 1100; // Rent increased
var internalTransfer = TransferTemplate('Transfer to Savings', 500, 'Checking', 'Savings');
var internalTransferCopy = internalTransfer.clone();
internalTransferCopy.amount = 700; // Increased transfer amount
print('Original Rent Payment: ${rentPayment.amount}');
print('Modified Rent Payment: ${rentPaymentCopy.amount}');
print('Original Transfer: ${internalTransfer.amount}');
print('Modified Transfer: ${internalTransferCopy.amount}');
}
```
The Prototype pattern allows us to create new transaction templates by cloning existing ones, which can be particularly useful when we want to create variations of common transactions without starting from scratch each time.
## Structural Patterns
As our "Ba Ba Bank" app continues to grow in complexity, we need to focus on how to organize our code effectively. Structural patterns help us compose classes and objects into larger structures while keeping these structures flexible and efficient.
### Adapter
As we expand "Ba Ba Bank", we decide to integrate a third-party payment system into our app. However, its interface is incompatible with our existing code. This is where the Adapter pattern becomes crucial.
The Adapter pattern allows objects with incompatible interfaces to work together. It acts as a wrapper between two objects, catching calls for one object and transforming them to format and interface recognizable by the second object. Let's implement an adapter for our payment system:
```dart
// Our payment system interface
abstract class PaymentProcessor {
Future<bool> processPayment(double amount);
}
// Third-party payment system with an incompatible interface
class ThirdPartyPaymentSystem {
Future<Map<String, dynamic>> makePayment(int cents) async {
// Simulating payment processing
await Future.delayed(Duration(seconds: 1));
return {'success': true, 'transaction_id': '12345'};
}
}
// Adapter for the third-party payment system
class ThirdPartyPaymentAdapter implements PaymentProcessor {
final ThirdPartyPaymentSystem _thirdPartySystem;
ThirdPartyPaymentAdapter(this._thirdPartySystem);
@override
Future<bool> processPayment(double amount) async {
var result = await _thirdPartySystem.makePayment((amount * 100).toInt());
return result['success'] == true;
}
}
// Usage
void main() async {
PaymentProcessor paymentProcessor = ThirdPartyPaymentAdapter(ThirdPartyPaymentSystem());
bool success = await paymentProcessor.processPayment(99.99);
if (success) {
print('Payment processed successfully');
} else {
print('Payment processing failed');
}
}
```
By using the Adapter pattern, we've successfully integrated the third-party payment system into our app without changing our existing PaymentProcessor interface. This makes it easy to switch between different payment providers in the future if needed.
### Bridge
As "Ba Ba Bank" grows, we realize that we need to support different types of notifications (email, SMS, push notifications) for various banking operations (account activity, fraud alerts, promotional offers). The Bridge pattern can help us manage this complexity.
The Bridge pattern separates an object's abstraction from its implementation so that the two can vary independently. Let's implement this for our notification system:
```dart
// Abstraction
abstract class Notification {
final NotificationSender sender;
Notification(this.sender);
void send();
}
// Implementor
abstract class NotificationSender {
void sendNotification(String message);
}
// Concrete Abstractions
class AccountActivityNotification extends Notification {
AccountActivityNotification(NotificationSender sender) : super(sender);
@override
void send() {
sender.sendNotification("There was activity on your account.");
}
}
class FraudAlertNotification extends Notification {
FraudAlertNotification(NotificationSender sender) : super(sender);
@override
void send() {
sender.sendNotification("Suspicious activity detected on your account!");
}
}
// Concrete Implementors
class EmailNotificationSender implements NotificationSender {
@override
void sendNotification(String message) {
print("Sending Email: $message");
}
}
class SMSNotificationSender implements NotificationSender {
@override
void sendNotification(String message) {
print("Sending SMS: $message");
}
}
// Usage
void main() {
var emailSender = EmailNotificationSender();
var smsSender = SMSNotificationSender();
var accountNotificationEmail = AccountActivityNotification(emailSender);
var fraudNotificationSMS = FraudAlertNotification(smsSender);
accountNotificationEmail.send();
fraudNotificationSMS.send();
}
```
The Bridge pattern allows us to combine different types of notifications with different sending methods, making our system more flexible and easier to extend.
### Composite
In "Ba Ba Bank", we want to create a feature that allows users to group their accounts and view combined balances. The Composite pattern is perfect for this scenario.
The Composite pattern lets you compose objects into tree structures to represent part-whole hierarchies. It lets clients treat individual objects and compositions of objects uniformly. Here's how we can implement it:
```dart
abstract class AccountComponent {
String getName();
double getBalance();
}
class BankAccount implements AccountComponent {
String name;
double balance;
BankAccount(this.name, this.balance);
@override
String getName() => name;
@override
double getBalance() => balance;
}
class AccountGroup implements AccountComponent {
String name;
List<AccountComponent> accounts = [];
AccountGroup(this.name);
void addAccount(AccountComponent account) {
accounts.add(account);
}
@override
String getName() => name;
@override
double getBalance() {
return accounts.fold(0, (sum, account) => sum + account.getBalance());
}
}
// Usage
void main() {
var checkingAccount = BankAccount('Checking', 1000);
var savingsAccount = BankAccount('Savings', 2000);
var stocksAccount = BankAccount('Stocks', 5000);
var personalAccounts = AccountGroup('Personal Accounts');
personalAccounts.addAccount(checkingAccount);
personalAccounts.addAccount(savingsAccount);
var rootGroup = AccountGroup('All Accounts');
rootGroup.addAccount(personalAccounts);
rootGroup.addAccount(stocksAccount);
print('Total Balance: ${rootGroup.getBalance()}'); // Output: Total Balance: 8000
print('Personal Accounts Balance: ${personalAccounts.getBalance()}'); // Output: Personal Accounts Balance: 3000
}
```
The Composite pattern allows us to create complex account structures while still being able to work with individual accounts and groups of accounts through the same interface.
### Decorator
As we develop the account features for "Ba Ba Bank", we realize that we want to be able to add additional behaviors to accounts dynamically. For example, we might want to add overdraft protection or automatic savings to certain accounts. The Decorator pattern is ideal for this situation.
The Decorator pattern allows behavior to be added to individual objects, either statically or dynamically, without affecting the behavior of other objects from the same class. Here's how we can implement it:
```dart
abstract class Account {
String getDescription();
double getBalance();
void credit(double amount);
bool debit(double amount);
}
class BasicAccount implements Account {
String _description;
double _balance;
BasicAccount(this._description, this._balance);
@override
String getDescription() => _description;
@override
double getBalance() => _balance;
@override
void credit(double amount) {
_balance += amount;
}
@override
bool debit(double amount) {
if (_balance >= amount) {
_balance -= amount;
return true;
}
return false;
}
}
abstract class AccountDecorator implements Account {
final Account _account;
AccountDecorator(this._account);
@override
String getDescription() => _account.getDescription();
@override
double getBalance() => _account.getBalance();
@override
void credit(double amount) => _account.credit(amount);
@override
bool debit(double amount) => _account.debit(amount);
}
class OverdraftProtection extends AccountDecorator {
double _overdraftLimit;
OverdraftProtection(Account account, this._overdraftLimit) : super(account);
@override
String getDescription() => '${super.getDescription()} with Overdraft Protection';
@override
bool debit(double amount) {
if (super.getBalance() + _overdraftLimit >= amount) {
super.debit(amount);
return true;
}
return false;
}
}
class AutoSave extends AccountDecorator {
double _savePercentage;
AutoSave(Account account, this._savePercentage) : super(account);
@override
String getDescription() => '${super.getDescription()} with Auto Save';
@override
void credit(double amount) {
double saveAmount = amount * _savePercentage;
super.credit(amount - saveAmount);
print('Saved $saveAmount');
}
}
// Usage
void main() {
Account account = BasicAccount('Checking Account', 1000);
account = OverdraftProtection(account, 500);
account = AutoSave(account, 0.1);
print(account.getDescription());
print('Initial balance: ${account.getBalance()}');
account.credit(200);
print('After credit: ${account.getBalance()}');
bool success = account.debit(1500);
print('Debit ${success ? 'succeeded' : 'failed'}. New balance: ${account.getBalance()}');
}
```
The Decorator pattern allows us to add new behaviors to our accounts dynamically, without altering the existing account classes. This makes our system more flexible and easier to extend with new features.
### Facade
As "Ba Ba Bank" grows more complex, we need a way to simplify the interface for common banking operations. The Facade pattern can help us achieve this.
The Facade pattern provides a simplified interface to a complex subsystem. Let's implement a BankingFacade that simplifies the process of transferring money between accounts:
```dart
class AccountManager {
bool verifyAccount(String accountNumber) {
// Verify account logic
print('Verifying account $accountNumber');
return true;
}
}
class FundsManager {
bool checkSufficientFunds(String accountNumber, double amount) {
// Check funds logic
print('Checking funds in account $accountNumber');
return true;
}
}
class TransferManager {
void transfer(String fromAccount, String toAccount, double amount) {
// Transfer logic
print('Transferring $amount from $fromAccount to $toAccount');
}
}
class NotificationManager {
void sendNotification(String accountNumber, String message) {
// Notification logic
print('Sending notification to account $accountNumber: $message');
}
}
class BankingFacade {
final AccountManager _accountManager = AccountManager();
final FundsManager _fundsManager = FundsManager();
final TransferManager _transferManager = TransferManager();
final NotificationManager _notificationManager = NotificationManager();
bool transferMoney(String fromAccount, String toAccount, double amount) {
if (!_accountManager.verifyAccount(fromAccount) ||
!_accountManager.verifyAccount(toAccount)) {
return false;
}
if (!_fundsManager.checkSufficientFunds(fromAccount, amount)) {
return false;
}
_transferManager.transfer(fromAccount, toAccount, amount);
_notificationManager.sendNotification(fromAccount, 'Transfer of $amount sent to $toAccount');
_notificationManager.sendNotification(toAccount, 'Transfer of $amount received from $fromAccount');
return true;
}
}
// Usage
void main() {
var facade = BankingFacade();
facade.transferMoney('123456', '789012', 500);
}
```
The Facade pattern simplifies the complex process of transferring money between accounts into a single method call, hiding the complexities of account verification, funds checking, transfer execution, and notification sending from the client code.
### Flyweight
In "Ba Ba Bank", we might have a large number of transactions that share common properties. The Flyweight pattern can help us save memory by sharing common parts of state between multiple objects instead of keeping all of the data in each object.
The Flyweight pattern is used to minimize memory usage by sharing as much data as possible with other similar objects. Here's how we could implement it for transaction types:
```dart
class TransactionType {
final String name;
final String description;
TransactionType(this.name, this.description);
}
class TransactionTypeFactory {
final Map<String, TransactionType> _transactionTypes = {};
TransactionType getTransactionType(String name) {
if (!_transactionTypes.containsKey(name)) {
switch (name) {
case 'deposit':
_transactionTypes[name] = TransactionType('deposit', 'Money added to account');
break;
case 'withdrawal':
_transactionTypes[name] = TransactionType('withdrawal', 'Money removed from account');
break;
case 'transfer':
_transactionTypes[name] = TransactionType('transfer', 'Money moved between accounts');
break;
default:
throw ArgumentError('Unknown transaction type');
}
}
return _transactionTypes[name]!;
}
}
class Transaction {
final TransactionType type;
final double amount;
final DateTime date;
Transaction(this.type, this.amount, this.date);
void display() {
print('${type.name.toUpperCase()}: $amount on ${date.toIso8601String()}');
print('Description: ${type.description}');
}
}
// Usage
void main() {
var factory = TransactionTypeFactory();
var transactions = [
Transaction(factory.getTransactionType('deposit'), 100, DateTime.now()),
Transaction(factory.getTransactionType('withdrawal'), 50, DateTime.now()),
Transaction(factory.getTransactionType('transfer'), 75, DateTime.now()),
Transaction(factory.getTransactionType('deposit'), 200, DateTime.now()),
];
for (var transaction in transactions) {
transaction.display();
print('---');
}
}
```
The Flyweight pattern allows us to share the common TransactionType objects among multiple Transaction objects, potentially saving memory when dealing with a large number of transactions.
### Proxy
In "Ba Ba Bank", we might want to control access to certain sensitive operations or implement lazy loading of resource-heavy objects. The Proxy pattern can help us achieve this.
The Proxy pattern provides a surrogate or placeholder for another object to control access to it. Here's an example of how we might use a proxy to control access to a user's account information:
```dart
abstract class AccountInfo {
void displayAccountInfo();
}
class RealAccountInfo implements AccountInfo {
String accountNumber;
RealAccountInfo(this.accountNumber) {
_loadAccountInfo();
}
void _loadAccountInfo() {
print('Loading account info for $accountNumber from database...');
// Simulate loading data from database
}
@override
void displayAccountInfo() {
print('Account Number: $accountNumber');
print('Balance: \$1,000,000'); // Just an example
}
}
class AccountInfoProxy implements AccountInfo {
late RealAccountInfo _realAccountInfo;
String accountNumber;
String? _userRole;
AccountInfoProxy(this.accountNumber, this._userRole);
@override
void displayAccountInfo() {
if (_userRole == 'admin' || _userRole == 'account_owner') {
_realAccountInfo = RealAccountInfo(accountNumber);
_realAccountInfo.displayAccountInfo();
} else {
print('Access denied. You do not have permission to view this account info.');
}
}
}
// Usage
void main() {
var adminProxy = AccountInfoProxy('12345', 'admin');
var userProxy = AccountInfoProxy('12345', 'user');
print('Admin accessing account info:');
adminProxy.displayAccountInfo();
print('\nRegular user accessing account info:');
userProxy.displayAccountInfo();
}
```
The Proxy pattern allows us to add a level of indirection when accessing an object. In this case, we're using it to control access to account information based on the user's role, and to implement lazy loading of the account information.
## Behavioral Patterns
Behavioral patterns are concerned with algorithms and the assignment of responsibilities between objects. They characterize complex control flow that's difficult to follow at run-time. Let's explore how these patterns can be applied in our "Ba Ba Bank" application.
### Observer
In "Ba Ba Bank", we want to implement a feature that notifies users of any changes to their account balance. The Observer pattern is perfect for this scenario.
The Observer pattern defines a one-to-many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically. Here's how we can implement it:
```dart
abstract class Subject {
void registerObserver(Observer observer);
void removeObserver(Observer observer);
void notifyObservers();
}
abstract class Observer {
void update(double balance);
}
class Account implements Subject {
double _balance = 0;
final List<Observer> _observers = [];
double get balance => _balance;
void deposit(double amount) {
_balance += amount;
notifyObservers();
}
void withdraw(double amount) {
if (_balance >= amount) {
_balance -= amount;
notifyObservers();
}
}
@override
void registerObserver(Observer observer) {
_observers.add(observer);
}
@override
void removeObserver(Observer observer) {
_observers.remove(observer);
}
@override
void notifyObservers() {
for (var observer in _observers) {
observer.update(_balance);
}
}
}
class BalanceDisplay implements Observer {
@override
void update(double balance) {
print('Balance Display: Current balance is $balance');
}
}
class MobileNotification implements Observer {
@override
void update(double balance) {
print('Mobile Notification: Your balance has changed. New balance: $balance');
}
}
// Usage
void main() {
var account = Account();
var display = BalanceDisplay();
var notification = MobileNotification();
account.registerObserver(display);
account.registerObserver(notification);
account.deposit(1000);
account.withdraw(500);
}
```
The Observer pattern allows us to create a flexible notification system where multiple observers (like a balance display and a mobile notification system) can be notified of changes to an account's balance without tightly coupling these components to the Account class.
### Strategy
In "Ba Ba Bank", we want to offer different saving strategies for our customers. The Strategy pattern can help us implement this feature.
The Strategy pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. It lets the algorithm vary independently from clients that use it. Here's how we can implement it:
```dart
abstract class SavingsStrategy {
double calculateInterest(double balance);
}
class ConservativeSavingsStrategy implements SavingsStrategy {
@override
double calculateInterest(double balance) {
return balance * 0.01; // 1% interest
}
}
class ModerateSavingsStrategy implements SavingsStrategy {
@override
double calculateInterest(double balance) {
return balance * 0.02; // 2% interest
}
}
class AggressiveSavingsStrategy implements SavingsStrategy {
@override
double calculateInterest(double balance) {
return balance * 0.05; // 5% interest
}
}
class SavingsAccount {
double _balance;
SavingsStrategy _strategy;
SavingsAccount(this._balance, this._strategy);
void setStrategy(SavingsStrategy strategy) {
_strategy = strategy;
}
void addInterest() {
double interest = _strategy.calculateInterest(_balance);
_balance += interest;
print('Added interest: $interest. New balance: $_balance');
}
}
// Usage
void main() {
var account = SavingsAccount(1000, ConservativeSavingsStrategy());
account.addInterest();
account.setStrategy(ModerateSavingsStrategy());
account.addInterest();
account.setStrategy(AggressiveSavingsStrategy());
account.addInterest();
}
```
The Strategy pattern allows us to define a family of algorithms (in this case, different savings strategies), encapsulate each one, and make them interchangeable. This makes it easy to add new strategies in the future without modifying the SavingsAccount class.
### Command
In "Ba Ba Bank", we want to implement a transaction system that supports undoing operations. The Command pattern is ideal for this scenario.
The Command pattern turns a request into a stand-alone object that contains all information about the request. This transformation lets you pass requests as a method arguments, delay or queue a request's execution, and support undoable operations. Here's how we can implement it:
```dart
abstract class Command {
void execute();
void undo();
}
class Account {
double _balance = 0;
void deposit(double amount) {
_balance += amount;
print('Deposited $amount. New balance: $_balance');
}
void withdraw(double amount) {
if (_balance >= amount) {
_balance -= amount;
print('Withdrawn $amount. New balance: $_balance');
} else {
print('Insufficient funds');
}
}
double get balance => _balance;
}
class DepositCommand implements Command {
final Account _account;
final double _amount;
DepositCommand(this._account, this._amount);
@override
void execute() {
_account.deposit(_amount);
}
@override
void undo() {
_account.withdraw(_amount);
}
}
class WithdrawCommand implements Command {
final Account _account;
final double _amount;
WithdrawCommand(this._account, this._amount);
@override
void execute() {
_account.withdraw(_amount);
}
@override
void undo() {
_account.deposit(_amount);
}
}
class TransactionManager {
final List<Command> _commands = [];
int _currentIndex = -1;
void executeCommand(Command command) {
command.execute();
_commands.add(command);
_currentIndex++;
}
void undo() {
if (_currentIndex >= 0) {
_commands[_currentIndex].undo();
_currentIndex--;
} else {
print('No more commands to undo');
}
}
void redo() {
if (_currentIndex < _commands.length - 1) {
_currentIndex++;
_commands[_currentIndex].execute();
} else {
print('No more commands to redo');
}
}
}
// Usage
void main() {
var account = Account();
var manager = TransactionManager();
manager.executeCommand(DepositCommand(account, 100));
manager.executeCommand(WithdrawCommand(account, 50));
manager.executeCommand(DepositCommand(account, 200));
print('Current balance: ${account.balance}');
manager.undo();
print('After undo: ${account.balance}');
manager.redo();
print('After redo: ${account.balance}');
}
```
The Command pattern allows us to encapsulate each bank transaction as a Command object. This makes it easy to implement undo and redo functionality, as well as to queue or log transactions.
### State
In "Ba Ba Bank", we want to implement different account states (e.g., standard, gold, platinum) with different behaviors. The State pattern can help us manage this complexity.
The State pattern allows an object to alter its behavior when its internal state changes. The object will appear to change its class. Here's how we can implement it:
```dart
abstract class AccountState {
void deposit(Account account, double amount);
void withdraw(Account account, double amount);
}
class StandardState implements AccountState {
@override
void deposit(Account account, double amount) {
account.balance += amount;
print('Standard account: Deposited $amount. New balance: ${account.balance}');
if (account.balance > 10000) {
account.setState(GoldState());
}
}
@override
void withdraw(Account account, double amount) {
if (account.balance >= amount) {
account.balance -= amount;
print('Standard account: Withdrawn $amount. New balance: ${account.balance}');
} else {
print('Standard account: Insufficient funds');
}
}
}
class GoldState implements AccountState {
@override
void deposit(Account account, double amount) {
account.balance += amount * 1.1; // 10% bonus
print('Gold account: Deposited $amount with 10% bonus. New balance: ${account.balance}');
if (account.balance > 20000) {
account.setState(PlatinumState());
}
}
@override
void withdraw(Account account, double amount) {
if (account.balance >= amount) {
account.balance -= amount;
print('Gold account: Withdrawn $amount. New balance: ${account.balance}');
} else {
print('Gold account: Insufficient funds');
}
if (account.balance < 10000) {
account.setState(StandardState());
}
}
}
class PlatinumState implements AccountState {
@override
void deposit(Account account, double amount) {
account.balance += amount * 1.2; // 20% bonus
print('Platinum account: Deposited $amount with 20% bonus. New balance: ${account.balance}');
}
@override
void withdraw(Account account, double amount) {
account.balance -= amount;
print('Platinum account: Withdrawn $amount. New balance: ${account.balance}');
if (account.balance < 20000) {
account.setState(GoldState());
}
}
}
class Account {
AccountState _state;
double _balance = 0;
Account() : _state = StandardState();
void setState(AccountState state) {
_state = state;
print('Account state changed to ${state.runtimeType}');
}
void deposit(double amount) {
_state.deposit(this, amount);
}
void withdraw(double amount) {
_state.withdraw(this, amount);
}
double get balance => _balance;
set balance(double value) => _balance = value;
}
// Usage
void main() {
var account = Account();
account.deposit(5000);
account.deposit(7000);
account.withdraw(3000);
account.deposit(15000);
account.withdraw(10000);
}
```
The State pattern allows the Account object to change its behavior when its balance changes, without using large conditional statements. Each state is encapsulated in its own class, making it easy to add new states or modify existing ones.
### Chain of Responsibility
In "Ba Ba Bank", we want to implement a loan approval system where different levels of employees can approve loans of different sizes. The Chain of Responsibility pattern is perfect for this scenario.
The Chain of Responsibility pattern passes requests along a chain of handlers. Upon receiving a request, each handler decides either to process the request or to pass it to the next handler in the chain. Here's how we can implement it:
```dart
abstract class LoanHandler {
LoanHandler? _nextHandler;
void setNext(LoanHandler handler) {
_nextHandler = handler;
}
void handleRequest(Loan loan);
}
class Loan {
final double amount;
Loan(this.amount);
}
class JuniorOfficer extends LoanHandler {
@override
void handleRequest(Loan loan) {
if (loan.amount <= 10000) {
print('Junior Officer approves loan of ${loan.amount}');
} else if (_nextHandler != null) {
_nextHandler!.handleRequest(loan);
}
}
}
class SeniorOfficer extends LoanHandler {
@override
void handleRequest(Loan loan) {
if (loan.amount <= 50000) {
print('Senior Officer approves loan of ${loan.amount}');
} else if (_nextHandler != null) {
_nextHandler!.handleRequest(loan);
}
}
}
class Manager extends LoanHandler {
@override
void handleRequest(Loan loan) {
if (loan.amount <= 100000) {
print('Manager approves loan of ${loan.amount}');
} else {
print('Loan of ${loan.amount} requires executive approval');
}
}
}
// Usage
void main() {
var juniorOfficer = JuniorOfficer();
var seniorOfficer = SeniorOfficer();
var manager = Manager();
juniorOfficer.setNext(seniorOfficer);
seniorOfficer.setNext(manager);
juniorOfficer.handleRequest(Loan(5000));
juniorOfficer.handleRequest(Loan(25000));
juniorOfficer.handleRequest(Loan(75000));
juniorOfficer.handleRequest(Loan(200000));
}
```
The Chain of Responsibility pattern allows us to create a chain of loan handlers. Each handler has the ability to process a request or pass it to the next handler in the chain. This makes it easy to add new handlers or change the order of handlers without modifying the client code.
### Memento
In "Ba Ba Bank", we want to implement a feature that allows users to save and restore the state of their account settings. The Memento pattern is ideal for this scenario.
The Memento pattern lets you save and restore the previous state of an object without revealing the details of its implementation. Here's how we can implement it:
```dart
class AccountSettings {
bool _notificationsEnabled;
String _language;
String _theme;
AccountSettings(this._notificationsEnabled, this._language, this._theme);
void setSettings(bool notifications, String language, String theme) {
_notificationsEnabled = notifications;
_language = language;
_theme = theme;
}
AccountSettingsMemento save() {
return AccountSettingsMemento(_notificationsEnabled, _language, _theme);
}
void restore(AccountSettingsMemento memento) {
_notificationsEnabled = memento.notificationsEnabled;
_language = memento.language;
_theme = memento.theme;
}
@override
String toString() {
return 'AccountSettings: {notifications: $_notificationsEnabled, language: $_language, theme: $_theme}';
}
}
class AccountSettingsMemento {
final bool notificationsEnabled;
final String language;
final String theme;
AccountSettingsMemento(this.notificationsEnabled, this.language, this.theme);
}
class AccountSettingsCaretaker {
AccountSettingsMemento? _memento;
void saveSettings(AccountSettings settings) {
_memento = settings.save();
}
void restoreSettings(AccountSettings settings) {
if (_memento != null) {
settings.restore(_memento!);
}
}
}
// Usage
void main() {
var settings = AccountSettings(true, 'English', 'Light');
var caretaker = AccountSettingsCaretaker();
print('Original settings: $settings');
caretaker.saveSettings(settings);
settings.setSettings(false, 'Spanish', 'Dark');
print('Modified settings: $settings');
caretaker.restoreSettings(settings);
print('Restored settings: $settings');
}
```
The Memento pattern allows us to save and restore the state of the AccountSettings object without exposing its internal structure. This is particularly useful for implementing "undo" functionality or for saving user preferences.
## Architectural Patterns
Architectural patterns are high-level strategies that concern large-scale components and the global properties and mechanisms of a system. They provide an organized structure to our Flutter application, making it easier to develop, maintain, and scale.
### MVVM (Model-View-ViewModel)
MVVM is a design pattern that separates the development of the graphical user interface (View) from the business logic and data (Model) via an intermediary (ViewModel). This separation enhances modularity and makes it easier to maintain and test the code. In "Ba Ba Bank", we can use MVVM to structure our account overview screen.
Here's how we might implement MVVM in our Flutter app:
```dart
import 'package:flutter/material.dart';
import 'package:provider/provider.dart';
// Model
class Account {
String id;
String type;
double balance;
Account(this.id, this.type, this.balance);
}
// ViewModel
class AccountViewModel extends ChangeNotifier {
Account _account;
AccountViewModel(this._account);
String get accountId => _account.id;
String get accountType => _account.type;
double get balance => _account.balance;
void deposit(double amount) {
_account.balance += amount;
notifyListeners();
}
void withdraw(double amount) {
if (_account.balance >= amount) {
_account.balance -= amount;
notifyListeners();
}
}
}
// View
class AccountView extends StatelessWidget {
@override
Widget build(BuildContext context) {
return ChangeNotifierProvider(
create: (context) => AccountViewModel(Account('123', 'Savings', 1000)),
child: Consumer<AccountViewModel>(
builder: (context, viewModel, child) {
return Scaffold(
appBar: AppBar(title: Text('Account Overview')),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text('Account ID: ${viewModel.accountId}'),
Text('Type: ${viewModel.accountType}'),
Text('Balance: \$${viewModel.balance.toStringAsFixed(2)}'),
ElevatedButton(
child: Text('Deposit \$100'),
onPressed: () => viewModel.deposit(100),
),
ElevatedButton(
child: Text('Withdraw \$50'),
onPressed: () => viewModel.withdraw(50),
),
],
),
),
);
},
),
);
}
}
// Usage
void main() {
runApp(MaterialApp(home: AccountView()));
}
```
In this MVVM implementation:
- The Model (Account) represents the data and business logic.
- The ViewModel (AccountViewModel) acts as an intermediary between the Model and the View. It exposes data and commands that the View can use.
- The View (AccountView) is responsible for the UI layout and binds to properties and commands exposed by the ViewModel.
MVVM allows us to separate concerns, making our code more modular and easier to test. The ViewModel can be tested independently of the UI, and the View can be easily modified without affecting the underlying logic.
### BLoC (Business Logic Component)
BLoC is a design pattern that helps separate the presentation layer from the business logic. It relies heavily on streams and reactive programming. In "Ba Ba Bank", we can use BLoC to manage the state of a transaction history screen.
Here's an example of how we might implement BLoC:
```dart
import 'dart:async';
import 'package:flutter/material.dart';
import 'package:flutter_bloc/flutter_bloc.dart';
// Events
abstract class TransactionEvent {}
class LoadTransactions extends TransactionEvent {}
class AddTransaction extends TransactionEvent {
final String description;
final double amount;
AddTransaction(this.description, this.amount);
}
// States
abstract class TransactionState {}
class TransactionInitial extends TransactionState {}
class TransactionLoading extends TransactionState {}
class TransactionLoaded extends TransactionState {
final List<Transaction> transactions;
TransactionLoaded(this.transactions);
}
// Model
class Transaction {
final String id;
final String description;
final double amount;
final DateTime date;
Transaction(this.id, this.description, this.amount, this.date);
}
// BLoC
class TransactionBloc extends Bloc<TransactionEvent, TransactionState> {
TransactionBloc() : super(TransactionInitial());
@override
Stream<TransactionState> mapEventToState(TransactionEvent event) async* {
if (event is LoadTransactions) {
yield TransactionLoading();
// Simulating API call
await Future.delayed(Duration(seconds: 1));
yield TransactionLoaded([
Transaction('1', 'Grocery Shopping', -50.0, DateTime.now().subtract(Duration(days: 1))),
Transaction('2', 'Salary', 1000.0, DateTime.now().subtract(Duration(days: 2))),
]);
} else if (event is AddTransaction) {
if (state is TransactionLoaded) {
final currentTransactions = (state as TransactionLoaded).transactions;
yield TransactionLoaded([
Transaction(
DateTime.now().millisecondsSinceEpoch.toString(),
event.description,
event.amount,
DateTime.now(),
),
...currentTransactions,
]);
}
}
}
}
// View
class TransactionHistoryPage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return BlocProvider(
create: (context) => TransactionBloc()..add(LoadTransactions()),
child: Scaffold(
appBar: AppBar(title: Text('Transaction History')),
body: BlocBuilder<TransactionBloc, TransactionState>(
builder: (context, state) {
if (state is TransactionLoading) {
return Center(child: CircularProgressIndicator());
} else if (state is TransactionLoaded) {
return ListView.builder(
itemCount: state.transactions.length,
itemBuilder: (context, index) {
final transaction = state.transactions[index];
return ListTile(
title: Text(transaction.description),
subtitle: Text(transaction.date.toString()),
trailing: Text('\$${transaction.amount.toStringAsFixed(2)}'),
);
},
);
}
return Center(child: Text('No transactions'));
},
),
floatingActionButton: FloatingActionButton(
child: Icon(Icons.add),
onPressed: () {
context.read<TransactionBloc>().add(AddTransaction('New Transaction', -30.0));
},
),
),
);
}
}
// Usage
void main() {
runApp(MaterialApp(home: TransactionHistoryPage()));
}
```
In this BLoC implementation:
- Events (TransactionEvent) represent user actions or system events.
- States (TransactionState) represent the different states our UI can be in.
- The BLoC (TransactionBloc) manages the business logic, converting events to states.
- The View (TransactionHistoryPage) responds to state changes and sends events to the BLoC.
BLoC helps us manage complex state in a predictable way, making our app more maintainable and testable.
### Repository Pattern
The Repository pattern adds an abstraction layer between the data source and the business logic of an application. In "Ba Ba Bank", we can use this pattern to abstract away the details of how we fetch and store user data.
Here's an example of how we might implement the Repository pattern:
```dart
import 'dart:async';
// Model
class User {
final String id;
final String name;
final String email;
User(this.id, this.name, this.email);
factory User.fromJson(Map<String, dynamic> json) {
return User(json['id'], json['name'], json['email']);
}
Map<String, dynamic> toJson() {
return {'id': id, 'name': name, 'email': email};
}
}
// Repository Interface
abstract class UserRepository {
Future<User> getUser(String id);
Future<void> updateUser(User user);
}
// API Implementation
class ApiUserRepository implements UserRepository {
@override
Future<User> getUser(String id) async {
// Simulating API call
await Future.delayed(Duration(seconds: 1));
return User(id, 'John Doe', 'john@example.com');
}
@override
Future<void> updateUser(User user) async {
// Simulating API call
await Future.delayed(Duration(seconds: 1));
print('User updated: ${user.toJson()}');
}
}
// Local Storage Implementation
class LocalUserRepository implements UserRepository {
final Map<String, User> _storage = {};
@override
Future<User> getUser(String id) async {
// Simulating local storage retrieval
await Future.delayed(Duration(milliseconds: 100));
return _storage[id] ?? User(id, 'Unknown', 'unknown@example.com');
}
@override
Future<void> updateUser(User user) async {
// Simulating local storage update
await Future.delayed(Duration(milliseconds: 100));
_storage[user.id] = user;
print('User updated locally: ${user.toJson()}');
}
}
// Usage
void main() async {
UserRepository apiRepo = ApiUserRepository();
UserRepository localRepo = LocalUserRepository();
var user = await apiRepo.getUser('123');
print('User from API: ${user.name}');
await localRepo.updateUser(user);
var localUser = await localRepo.getUser('123');
print('User from local storage: ${localUser.name}');
}
```
The Repository pattern allows us to abstract away the data source, making it easy to switch between different data sources (like API and local storage) without changing the rest of our application code. This is particularly useful in mobile applications where we might want to cache data locally for offline use.
### Clean Architecture
Clean Architecture is a software design philosophy that separates the elements of a design into ring levels. The main rule of clean architecture is that code dependencies can only come from the outer levels inward. In "Ba Ba Bank", we can use Clean Architecture to structure our entire application.
Here's a simplified example of how we might implement Clean Architecture:
```dart
// Entities (Enterprise Business Rules)
class Account {
final String id;
double balance;
Account(this.id, this.balance);
}
// Use Cases (Application Business Rules)
abstract class TransferMoney {
Future<void> execute(String fromId, String toId, double amount);
}
class TransferMoneyUseCase implements TransferMoney {
final AccountRepository repository;
TransferMoneyUseCase(this.repository);
@override
Future<void> execute(String fromId, String toId, double amount) async {
var fromAccount = await repository.getAccount(fromId);
var toAccount = await repository.getAccount(toId);
if (fromAccount.balance < amount) {
throw Exception('Insufficient funds');
}
fromAccount.balance -= amount;
toAccount.balance += amount;
await repository.updateAccount(fromAccount);
await repository.updateAccount(toAccount);
}
}
// Interface Adapters
abstract class AccountRepository {
Future<Account> getAccount(String id);
Future<void> updateAccount(Account account);
}
class AccountRepositoryImpl implements AccountRepository {
// This could be using an API client or local database
final Map<String, Account> _accounts = {
'1': Account('1', 1000),
'2': Account('2', 500),
};
@override
Future<Account> getAccount(String id) async {
await Future.delayed(Duration(milliseconds: 100)); // Simulating I/O
return _accounts[id] ?? Account(id, 0);
}
@override
Future<void> updateAccount(Account account) async {
await Future.delayed(Duration(milliseconds: 100)); // Simulating I/O
_accounts[account.id] = account;
}
}
// Frameworks & Drivers (UI, Database, External Interfaces)
class TransferMoneyViewModel {
final TransferMoney transferMoney;
TransferMoneyViewModel(this.transferMoney);
Future<void> transfer(String fromId, String toId, double amount) async {
try {
await transferMoney.execute(fromId, toId, amount);
print('Transfer successful');
} catch (e) {
print('Transfer failed: ${e.toString()}');
}
}
}
// Usage
void main() async {
var repository = AccountRepositoryImpl();
var useCase = TransferMoneyUseCase(repository);
var viewModel = TransferMoneyViewModel(useCase);
await viewModel.transfer('1', '2', 200);
var account1 = await repository.getAccount('1');
var account2 = await repository.getAccount('2');
print('Account 1 balance: ${account1.balance}');
print('Account 2 balance: ${account2.balance}');
}
```
In this Clean Architecture implementation:
- Entities represent the core business objects.
- Use Cases contain the business logic of the application.
- The Repository is an interface adapter that abstracts the data source.
- The ViewModel acts as a presenter, connecting the UI to the Use Cases.
Clean Architecture helps us create a system that is independent of frameworks, testable, and independent of the UI. This makes our "Ba Ba Bank" app more maintainable and adaptable to change.
## When to Use Design Patterns
While design patterns offer numerous benefits, it's crucial to use them judiciously. Here are some guidelines on when to apply design patterns:
1. Understand the problem: Before applying a pattern, make sure you fully understand the problem you're trying to solve.
2. Start simple: Don't overcomplicate your code with patterns if a simple solution works well.
3. Consider future changes: Apply patterns when you anticipate that the code will need to change or expand in the future.
4. Evaluate trade-offs: Each pattern has its advantages and potential drawbacks. Assess whether the benefits outweigh any disadvantages.
5. Follow YAGNI (You Aren't Gonna Need It): Don't add complexity by implementing functionality "just in case."
6. Use patterns consistently: If you decide to use a certain pattern, apply it consistently throughout your project.
7. Document pattern usage: Ensure that other developers on the team understand which patterns are being used and why.
Remember, the goal is not to use as many patterns as possible, but to solve problems effectively and create robust, scalable software.
## Conclusion
Throughout the development of our "BBB - Ba Ba Bank" application, we've explored how various design patterns can be applied to solve common problems and improve the structure of our code. From managing object creation with creational patterns to organizing complex structures with structural patterns, defining object interactions with behavioral patterns, and structuring our application with architectural patterns, each pattern has played a crucial role in building a robust and maintainable banking app.
By understanding these patterns and their appropriate use cases, you can write more efficient, readable, and maintainable Flutter applications. Remember that the effectiveness of a pattern depends on the specific context of your project. Always consider the trade-offs and choose the solution that best fits your needs.
As you continue to develop "Ba Ba Bank" and other Flutter applications, keep exploring these patterns, practice implementing them, and always strive to understand the underlying principles that make them effective.
## Additional Resources
To further your understanding of design patterns in software development and Flutter specifically, consider exploring these resources:
1. "Design Patterns: Elements of Reusable Object-Oriented Software" by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides - The classic book on design patterns.
2. "Flutter Design Patterns" by Mangirdas Kazlauskas - A comprehensive guide on implementing design patterns in Flutter.
3. Dart Design Patterns website (https://dart.dev/guides/language/effective-dart/design) - Official Dart language design patterns guide.
4. Flutter documentation (https://flutter.dev/docs) - The official Flutter documentation, which often demonstrates best practices and pattern usage.
5. "Clean Architecture: A Craftsman's Guide to Software Structure and Design" by Robert C. Martin - A great resource for understanding clean architecture principles.
Remember, the best way to master design patterns is through practice. Try implementing these patterns in your Flutter projects, analyze their impact, and continually refine your approach to software design.
As you've seen throughout this article, design patterns are powerful tools that can greatly enhance the quality, maintainability, and scalability of your Flutter applications. However, it's important to remember that patterns are not a one-size-fits-all solution. Each pattern should be applied thoughtfully, considering the specific needs and constraints of your project.
In our "BBB - Ba Ba Bank" application, we've demonstrated how various patterns can be used to solve different challenges:
1. Creational Patterns like Factory Method and Builder helped us manage the creation of complex objects such as bank accounts and financial reports.
2. Structural Patterns like Adapter and Decorator allowed us to compose objects and classes into larger structures, helping us integrate third-party payment systems and add new behaviors to our accounts dynamically.
3. Behavioral Patterns like Observer and Command helped us define clear communication patterns between objects, enabling features like real-time balance updates and undoable transactions.
4. Architectural Patterns like MVVM and Clean Architecture provided overall structure to our application, separating concerns and making our code more testable and maintainable.
As you continue to develop "Ba Ba Bank" or work on other Flutter projects, keep these patterns in mind, but also remember to:
- Start with the simplest solution that solves your problem. Don't over-engineer your code with unnecessary patterns.
- Refactor towards patterns when you see a clear benefit. It's often easier to recognize the need for a pattern as your code evolves.
- Communicate with your team about the patterns you're using. Shared understanding is crucial for maintaining a consistent codebase.
- Stay updated with the Flutter community. New patterns and best practices emerge as the framework evolves.
Lastly, remember that design patterns are tools to help you write better code, not rules that must be followed blindly. The best developers know not just how to apply patterns, but when to apply them—and when not to.
As you gain more experience with these patterns in real-world projects, you'll develop an intuition for when and how to apply them effectively. This knowledge will not only make you a better Flutter developer but will also enhance your overall software design skills.
We hope this comprehensive guide to design patterns in Flutter, as illustrated through our "BBB - Ba Ba Bank" application, has been helpful in your journey as a Flutter developer. Happy coding, and may your future Flutter projects be well-structured, maintainable, and successful!
## Further Learning
To continue your learning journey with design patterns and Flutter development, consider the following steps:
1. Practice implementing these patterns in small, focused projects. This will help you understand their nuances and trade-offs.
2. Join Flutter community forums and discuss pattern usage with other developers. You'll gain insights into real-world applications and challenges.
3. Contribute to open-source Flutter projects. This will expose you to how patterns are used in larger, collaborative environments.
4. Stay updated with Flutter's evolution. As the framework grows, new patterns and best practices may emerge.
5. Explore how these patterns are used in other programming languages and frameworks. This broader perspective will deepen your understanding of software design principles.
Remember, becoming proficient with design patterns is a journey. It takes time, practice, and reflection. But with each pattern you master, you'll become a more effective and versatile developer, capable of tackling increasingly complex challenges in your Flutter projects.

In JavaScript, object-oriented programming (OOP) is a programming paradigm that is based on the concept of “objects”, which are collections of data and functions that work together to perform certain tasks.
In OOP, objects are created from “classes”, which are templates that define the properties and methods of the objects they create.
**Advantages of OOP**
One of the key advantages of using OOP in JavaScript is that it allows you to organize your code in a more logical and manageable way. With OOP, you can create classes that represent real-world objects and define the properties and methods that those objects have. This makes it easier to understand and work with your code, especially as it grows in complexity.
Another benefit of OOP in JavaScript or programming is that it allows for code reuse and extensibility.
Once you have defined a class, you can create as many objects from that class as you need. This can save you a lot of time and effort because you don’t have to write the same code over and over again for each object.
Additionally, you can create new classes that inherit from existing classes, which allows you to reuse and extend the functionality of existing code.
**Getting started with OOP**
To get started with OOP in JavaScript, you first need to understand the concept of a class. In JavaScript, a class is a template that defines the properties and methods of the objects it creates. Here is an example of a simple class that represents a person:
```
class Person {
constructor(name, age) {
this.name = name;
this.age = age;
}
greet() {
console.log(`Hi, my name is ${this.name} and I am ${this.age} years old.`);
}
}
```
In this example, the Person class has two properties: name and age. It also has one method, greet(), which outputs a greeting to the console.
To create an object from this class, you use the new keyword followed by the name of the class, like this:
```
const person1 = new Person("John", 25);
const person2 = new Person("Jane", 30);
```
Once you have created an object, you can access its properties and methods using dot notation, like this:
**OOP Inheritance in JavaScript**
In addition to defining classes and creating objects, OOP in JavaScript also allows for inheritance. This means that you can create new classes that inherit the properties and methods of existing classes. For example, let’s say you want to create a Student class that represents a student at a school. The Student class could inherit from the Person class, like this:
```
class Student extends Person {
constructor(name, age, school) {
super(name, age);
this.school = school;
}
info() {
console.log(`${this.name} is ${this.age} years old and goes to ${this.school}.`);
}
}
```
**Four Pillars of OOPS**
The four pillars of object-oriented programming (OOP) in JavaScript are:
**Encapsulation:**
Encapsulation refers to the idea of wrapping data and functionality together inside an object. In OOP, objects are the basic building blocks of your code, and each object has its own properties and methods. This allows you to organize your code in a way that makes it easier to understand and work with.
For example, you might create a Person class that has properties like name and age, and methods like greet() and introduce().
**Abstraction**:
Abstraction is the process of hiding the details of an object’s implementation and only exposing the necessary information to the user. In OOP, you can use abstraction to make your code more modular and flexible.
For example, you can define an abstract class that provides a common interface for a group of related objects, without specifying how those objects are implemented.
**Inheritance:**
Inheritance is the process of creating new classes that inherit the properties and methods of existing classes. This allows you to reuse and extend existing code, which can save you time and effort.
For example, if you have a Person class that defines common properties and methods for a person, you can create a Student class that inherits from the Person class and adds additional functionality.
**Polymorphism:**
Polymorphism is the ability of different objects to respond to the same method call in different ways. In OOP, polymorphism allows you to create objects that share a common interface, but have different implementations. This makes your code more flexible and allows you to write code that is more easily maintainable and extensible.
For example, you can create a Shape class that defines a common draw() method, and then create subclasses for different types of shapes (e.g. Circle, Rectangle, etc.) that each implement the draw() method in their own way.
Here is an example of how these pillars of OOP might be used in a JavaScript program:
```
// Encapsulation: define a Person class with properties and methods
class Person {
constructor(name, age) {
this.name = name;
this.age = age;
}
greet() {
console.log(`Hi, my name is ${this.name} and I am ${this.age} years old.`);
}
}
// Inheritance: define a Student class that inherits from the Person class
class Student extends Person {
constructor(name, age, school) {
super(name, age);
this.school = school;
}
info() {
console.log(`${this.name} is ${this.age} years old and goes to ${this.school}.`);
}
}
// Abstraction: define an abstract Shape class with a common draw() method
abstract class Shape {
abstract draw(): void;
}
// Polymorphism: define subclasses of Shape that implement the draw() method in their own way
class Circle extends Shape {
draw() {
console.log("Drawing a circle...");
}
}
class Rectangle extends Shape {
draw() {
console.log("Drawing a rectangle...");
}
}
```
**Wrapping Up**
Object-oriented programming is a fundamental concept in JavaScript and can greatly improve the structure and organization of your code. By understanding and implementing concepts such as encapsulation, inheritance, and polymorphism, you can create more efficient and maintainable programs.
Whether you’re a beginner or an experienced developer, taking the time to master OOP in JavaScript will pay off in the long run. Thanks for reading, and happy coding. | adarshgupta101 |

- There are real-world examples out there showing how various fields have benefited from using AI to turn photos into engaging videos.
## Introduction
Pictures were once the go-to for telling stories, but in today's digital world, videos reign supreme for capturing and retaining attention. Creating high-quality videos from scratch is time-consuming. That's why image to video AI APIs come in, using smart tech tricks to quickly transform images into videos. These tools make high quality video creation, offering features like clear video quality, fast turnaround times, customized options, and the ability to add dynamic text captions.
## Understanding Image to Video AI API
To know how image to video AI API functions, we should start by understanding what AI and API mean. Artificial Intelligence (AI) is all about creating computer systems that can do things which usually need humans to work out. On the flip side, APIs are like bridges for software, letting different programs talk and work together.
When turning pictures into videos, image to video AI APIs keep stable diffusion. So you get a smooth flow from one frame to another without any jarring jumps, making your video look slick and professional. The generator steps in to spice up those still images by adding motion and vibrancy, bringing them to life in a way only moving pictures can.
### What is Image to Video AI API?
A image to video API is a business-friendly platforms that feature AI functionality focused on streamlining production tasks and improving video content. It enables developers to produce videos through programming, providing functions like uploading, programming, storing, encoding, and optimizing delivery.
### How Image to Video AI API Works
Image to video AI APIs produce videos using dynamic data. Developers integrate the image editing API into software applications or websites by including the code (JavaScript, Python, Bash, etc) and dependencies. Sending API request, the platform provides great solutions to analyze photos, identify objects and places, and create smooth transitions for a more realistic viewing experience. Once the video is rendered, developers can retrieve it using the provided URL and user interface.
## Key Features of Image to Video AI APIs
When you're looking into tools that can turn pictures into videos, there are the benefits and features to focus.

I'm still learning!
Hey everyone. I'm back.
And, yeah, I'm still making n00b TypeScript mistakes 😢
But luckily I've got some really clever coworkers that point out some awesome TypeScript tips while I continue to build [Open SaaS](https://OpenSaaS.sh) and make it the best, free, open-source SaaS starter for React & NodeJS.
[](https://OpenSaaS.sh)
And I'm going to share those tips with you today.
In the [first part of this series on TypeScript](https://dev.to/wasp/ive-been-writing-typescript-without-understanding-it-5ef4), I went into some fundamentals on what it is and how it works. I also touched on the `satisfies` keyword and some of the quirks around TypeScript's structural typing system.
In this episode, I'm going to teach you how to share a set of values across a large app (such as a SaaS app) by using a nifty technique to make sure that you never forget to update other parts of your app whenever new values are added or changed.
Let's jump right into some code then.
## Keeping track of values across a big app
In [Open SaaS](http://opensaas.sh), we wanted to assign some payment plan values we could use across the entire app, both front-end and back-end. For example, most SaaS apps have a few different products plans they might sell, like:
- a monthly `Hobby` subscription plan,
- a monthly `Pro` subscription plan,
- and a one-time payment product that gives the user 10 `Credits` they can redeem in the app (instead of a monthly plan).
So it seemed like a good idea to use an `enum` and to pass those plan values around and keep them consistent:
```tsx
export enum PaymentPlanId {
Hobby = 'hobby',
Pro = 'pro',
Credits10 = 'credits10',
}
```
Then, we could use this enum on the Pricing Page, as well as in our server-side functions.
```tsx
// ./client/PricingPage.tsx
import { PaymentPlanId } from '../payments/plans.ts'
export const planCards = [
{
name: 'Hobby',
id: PaymentPlanId.Hobby,
price: '$9.99',
description: 'All you need to get started',
features: ['Limited monthly usage', 'Basic support'],
},
{
name: 'Pro',
id: PaymentPlanId.Pro,
price: '$19.99',
description: 'Our most popular plan',
features: ['Unlimited monthly usage', 'Priority customer support'],
},
{
name: '10 Credits',
id: PaymentPlanId.Credits10,
price: '$9.99',
description: 'One-time purchase of 10 credits for your account',
features: ['Use credits for e.g. OpenAI API calls', 'No expiration date'],
},
];
export function PricingPage(props) {
return (
...
planCards.map(planCard => {
<PlanCard card={planCard} />
})
...
)
}
```
Above, you can see how we use the enum as the payment plan ID on our Pricing Page. Then, we pass that ID to our button click handler, and send it in our request to the server so we know which payment plan to process.
```tsx
// ./server/Payments.ts
export const stripePayment: StripePayment<PaymentPlanId, StripePaymentResult> = async (plan, context) => {
let stripePriceId;
if (plan === PaymentPlanId.Hobby) {
stripePriceId = process.env.STRIPE_HOBBY_SUBSCRIPTION_PRICE_ID!;
} else if (plan === PaymentPlanId.Pro) {
stripePriceId = process.env.STRIPE_PRO_SUBSCRIPTION_PRICE_ID!;
} else if (plan === PaymentPlanId.Credits10) {
stripePriceId = process.env.STRIPE_CREDITS_PRICE_ID!;
} else {
throw new HttpError(404, 'Invalid plan');
}
//...
```
The nice thing about using the enum here is that it’s easy to use consistently across the entire app. And in the case above, we use it to map our pricing plans to the price IDs that they were given when we created these products on Stripe, which we've saved as environment variables.
But with our current code, what happens if we decide to create a new plan, such as a 50 Credit one-time payment plan, and add it to our app?
```tsx
export enum PaymentPlanId {
Hobby = 'hobby',
Pro = 'pro',
Credits10 = 'credits10',
Credits50 = 'credits50'
}
```
Well, currently, we’d have to go through the app, find each place where we’re using `PaymentPlanID`, and add a reference to our new `Credits50` plan.
```tsx
// ./client/PricingPage.tsx
import { PaymentPlanId } from '../payments/plans.ts'
export const planCards = [
{
name: 'Hobby',
id: PaymentPlanId.Hobby,
//...
},
{
name: 'Pro',
id: PaymentPlanId.Pro,
price: '$19.99',
//...
},
{
name: '10 Credits',
id: PaymentPlanId.Credits10,
//...
},
{
name: '50 Credits',
id: PaymentPlanId.Credits50.
//...
}
];
export function PricingPage(props) {
return (
...
planCards.map(planCard => {
<PlanCard card={planCard} />
})
...
)
}
// ./server/Payments.ts
export const stripePayment: StripePayment<PaymentPlanId, StripePaymentResult> = async (plan, context) => {
let stripePriceId;
if (plan === PaymentPlanId.Hobby) {
stripePriceId = process.env.STRIPE_HOBBY_SUBSCRIPTION_PRICE_ID!;
} else if (plan === PaymentPlanId.Pro) {
//..
} else if (plan === PaymentPlanId.Credits50) {
stripePriceId = process.env.STRIPE_CREDITS_50_PRICE_ID!; // ✅
} else {
throw new HttpError(404, 'Invalid plan');
}
```
Ok. That might not seem too difficult, but what if you’re using `PaymentPlanId` in more than just two files? There is a really high chance you will forget to reference your new payment plan somewhere!
Wouldn’t it be cool if we could have TypeScript tell us when we forgot to add it somewhere? This is exactly the problem the `Record` type can help us solve.
Let’s take a look.
## Using Record Types to Keep Values in Sync
First off, a `Record` is a utility type to help us type objects. By using `Record` we can define exactly what types our keys and values should be.
The type `Record<X, Y>` on an object means "This object literal must define a _value of type Y for every possible value of type X_". In other words, Records enforce compile-time checks for exhaustiveness.
In practical terms, what this means is that when someone adds a new value to the enum `PaymentPlanId`, the compiler won't let them forget about adding an appropriate mapping
This keeps our object mappings strong and safe.
Let's take a look at how it works with our `PaymentPlanId` enum in action. Let’s first look at how we could use a `Record` type to make sure we always have all the Payment Plans included on our pricing page:
```tsx
export enum PaymentPlanId {
Hobby = 'hobby',
Pro = 'pro',
Credits10 = 'credits10',
}
// ./client/PricingPage.tsx
export const planCards: Record<PaymentPlanId, PaymentPlanCard> = {
[PaymentPlanId.Hobby]: {
name: 'Hobby',
price: '$9.99',
description: 'All you need to get started',
features: ['Limited monthly usage', 'Basic support'],
},
[PaymentPlanId.Pro]: {
name: 'Pro',
price: '$19.99',
description: 'Our most popular plan',
features: ['Unlimited monthly usage', 'Priority customer support'],
},
[PaymentPlanId.Credits10]: {
name: '10 Credits',
price: '$9.99',
description: 'One-time purchase of 10 credits for your account',
features: ['Use credits for e.g. OpenAI API calls', 'No expiration date'],
}
};
export function PricingPage(props) {
return (
...
planCards.map(planCard => {
<PlanCard card={planCard} />
})
...
)
}
```
Now `planCards` is a `Record` type where the key has to be a `PaymentPlanId`, and the value must be an object with the payment plan information (`PaymentPlanCard`).
The magic here happens when we add a new value to our enum, such as `Credits50`:
```tsx
export enum PaymentPlanId {
Hobby = 'hobby',
Pro = 'pro',
Credits10 = 'credits10',
Credits50 = 'credits50'
}
```
Now TypeScript is giving us a compile-time error, `Property '[PaymentPlanId.Credits50]' is missing...`, to let us know that our Pricing Page doesn’t contain a card for our new plan.
Now you see the simple power of using a `Record` to keep values consistent. But we shouldn’t only do this for the front-end, let’s fix our server-side function that process payments for our different plans:
```tsx
// ./payments/plans.ts
export const paymentPlans: Record<PaymentPlanId, PaymentPlan> = {
[PaymentPlanId.Hobby]: {
stripePriceId: process.env.STRIPE_HOBBY_SUBSCRIPTION_PRICE_ID,
kind: 'subscription'
},
[PaymentPlanId.Pro]: {
stripePriceId: process.env.STRIPE_PRO_SUBSCRIPTION_PRICE_ID,
kind: 'subscription'
},
[PaymentPlanId.Credits10]: {
stripePriceId: process.env.STRIPE_CREDITS_PRICE_ID,
kind: 'credits',
amount: 10
},
[PaymentPlanId.Credits50]: {
stripePriceId: process.env.STRIPE_CREDITS_PRICE_ID,
kind: 'credits',
amount: 50
},
};
// ./server/Payments.ts
import { paymentPlans } from './payments/plans.ts'
export const stripePayment: StripePayment<PaymentPlanId, StripePaymentResult> = async (planId, context) => {
const priceId = paymentPlans[planId].stripePriceId
//...
```
What’s really cool about this technique, is that by defining `paymentPlans` with a `Record` type that uses our `PaymentPlanId` enum as the key value, we can always be sure we never forget any of our payment plans or make a silly typo. TypeScript will save us here.
Plus, we can switch out our entire `if else` block for a clean one-liner:
```tsx
const priceId = paymentPlans[planId].stripePriceId
```
Smoooooth :)
It’s also very likely that we will use the `paymentPlans` object elsewhere in our code, making it cleaner and much more maintainable. A real win-win-win situation, thanks to the `Record` type.
## Preferring Mappings with `Record` over `if else`
Just to further bring the point home of how `Record` can make our lives easier as developers, let’s look at another example of using it client-side to display some user account information.
First, let’s summarize what’s going on in our app and how we used our friendly utility type already:
1. we defined the `PaymentPlanId` enum to centralize our payment plan IDs and keep them consistent across the app.
2. we mapped objects using `Record` in the client and server code to make sure that all our Payment Plans are present in these objects, that way if we add a new payment plan we will get TypeScript warnings that they must also be added to these objects as well.
Now, we use those IDs on the front-end and pass them to our server-side call to process the payment for the correct plan when a user clicks the `Buy Plan` button. When the user completes the payment, we save that `PaymentPlanId` to a property on the user model in our database, e.g. `user.paymentPlan`.
Let’s now take a look at how we can again use that value, along with objects mapped with the `Record` type, to conditionally retrieve account information in a way that’s much cleaner and more type-safe than `if else` or `switch` blocks can be:
```tsx
// ./client/AccountPage.tsx
export function AccountPage({ user }: { user: User }) {
const paymentPlanIdToInfo: Record<PaymentPlanId, string> = {
[PaymentPlanId.Hobby]: 'You are subscribed to the monthly Hobby plan.',
[PaymentPlanId.Pro]: 'You are subscribed to the monthly Pro plan.',
[PaymentPlanId.Credits10]: `You purchased the 10 Credits plan and have ${user.credits} left`,
[PaymentPlanId.Credits50]: `You purchased the 50 Credits plan and have ${user.credits} left`
};
return (
<div>{ paymentPlanIdToInfo[user.paymentPlan] }</div>
)
}
```
Again, all we have to do is update our `PaymentPlanId` enum to include any additional payment plans we may create, and TypeScript will warn us that we need to add it to all mappings where it was used as a `Record` key or value type.
In comparison, if we were using an `if else` block, we’d get no such warnings. We’d also have no protection against silly typos, leading to buggier, harder to maintain code:
```tsx
export function AccountPage({ user }: { user: User }) {
let infoMessage = '';
if(user.paymentPlan === PaymentPlanId.Hobby) {
infoMessage = 'You are subscribed to the monthly Hobby plan.';
// ❌ We forgot the Pro plan here, but will get no warning from TS!
} else if(user.paymentPlan === PaymentPlanId.Credits10) {
infoMessage = `You purchased the 10 Credits plan and have ${user.credits} left`;
// ❌ Below we used the wrong user property to compare to PaymentPlanId.
// Although it's acceptable code, it's not the correct type!
} else if(user.paymentStatus === PaymentPlanId.Credits50) {
infoMessage = `You purchased the 50 Credits plan and have ${user.credits} left`;
}
return (
<div>{ infoMessage }</div>
)
}
```
But there are times when we need more complex condition checking and the ability to handle any side cases individually. In such cases, we’re definitely better off using `if else` or `switch` statements.
So how can we get the same type-checking thoroughness of `Record` mappings, but with the benefits of an `if else` or `switch`?
---
**By the way…**
We're working hard at [Wasp](https://wasp-lang.dev/) to create the best open-source React/NodeJS framework that allows you to move fast!
That's why we've got ready-to-use full-stack app templates with a simple CLI command, like [Open SaaS](https://opensaas.sh), or a ToDo App with TypeScript. All you have to do is install Wasp:
```sh
curl -sSL https://get.wasp-lang.dev/installer.sh | sh
```
and run:
```sh
wasp new -t saas
# or
wasp new -t todo-ts
```
You'll get a full-stack templates with Auth and end-to-end TypeSafety, out of the box, to help you learn TypeScript, or to get you started building your profitable side-project quickly and safely :)
---
### Using `never`… sometimes
The answer to the above question is that we need a way to check for “exhaustiveness” in our `switch` statements. Let’s use the example below:
```tsx
// ./payments/Stripe.ts
const plan = paymentPlans[planId];
let subscriptionPlan: PaymentPlanId | undefined;
let numOfCreditsPurchased: number | undefined;
switch (plan.kind) {
case 'subscription':
subscriptionPlan = planId;
break;
case 'credits':
numOfCreditsPurchased = plan.effect.amount;
break;
}
```
We’ve reached for a relatively simple `switch` statement here instead of a mapping with the `Record` type because assigning the values of our two variables, `subscriptionPlan` and `numOfCreditsPurchased` , is a lot cleaner and easier to read this way.
But now we’ve lost the exhaustive type checking we’d get with a `Record` type mapping, so if we were to add a new `plan.kind`, like `metered-usage` for example, we’d get no warning from TypeScript in our `switch` statement above.
Boo!
Luckily, there is an easy solution. We can create a utility function that will do the checking for us:
```tsx
export function assertUnreachable(x: never): never {
throw Error('This code should be unreachable');
}
```
This might look weird, but what’s important is the use of the `never` type. It tells TypeScript that this value should “never” occur.
So that we can see how this utility function works, let’s go ahead now and add our new plan `kind`:
```tsx
// ./payments/plans.ts
export const paymentPlans: Record<PaymentPlanId, PaymentPlan> = {
[PaymentPlanId.Hobby]: {
stripePriceId: process.env.STRIPE_HOBBY_SUBSCRIPTION_PRICE_ID,
kind: 'subscription'
},
[PaymentPlanId.Pro]: {
stripePriceId: process.env.STRIPE_PRO_SUBSCRIPTION_PRICE_ID,
kind: 'subscription'
},
[PaymentPlanId.Credits10]: {
stripePriceId: process.env.STRIPE_CREDITS_PRICE_ID,
kind: 'credits',
amount: 10
},
// ✅ Our new payment plan kind
[PaymentPlanId.MeteredUsage]: {
stripePriceId: process.env.STRIPE_METERED_PRICE_ID,
kind: 'metered-usage'
};
```
Now, if we add `assertUnreachable`, check out what happens:
Ah ha! We’re getting an error `Argument of type '{ kind: "metered-usage"; }' is not assignable to parameter of type 'never'`
Perfect. We’ve introduced exhaustive type checking into our `switch` statement. This code is actually never meant to be run, it’s just there to provide friendly warnings for us in advance.
To get TypeScript to stop being mad at us in this case, all we have to do is…:
```tsx
switch (plan.kind) {
case 'subscription':
subscriptionPlan = planId;
break;
case 'credits':
numOfCreditsPurchased = plan.effect.amount;
break;
// ✅ Add our new payment plan kind
case 'metered-usage'
currentUsage = getUserCurrentUsage(user);
break;
default:
assertUnreachable(plan.kind);
}
```
This is great. We get all the benefits of dealing with more complex logic in a `switch` statement, with the assurance that we'll never forget any possible `plan.kind` case being used in our app.
Stuff like this makes code way less error prone, and much easier to debug. A little bit of preparation goes a long way!

Developing dynamic and interactive web apps is crucial in the dynamic and ever-changing world of web development. The speed and versatility of React, a JavaScript toolkit for creating user interfaces, have led to its great popularity. However, PHP is still a strong option for server-side programming. This tutorial will show you how to easily combine the functionality of a PHP backend and React front-end to utilize their respective strengths fully.
## Understanding the Distinct Roles of PHP and React
## What Is PHP
The term PHP is an acronym for Hypertext Preprocessor. It is a server-side scripting language that is used for web development. It can be easily embedded with HTML files. HTML codes can also be written in a PHP file.
## Merits Of PHP
Below are a few Merits of PHP
**Ease of Learning and Use**:
- PHP is known for its straightforward syntax, which is relatively easy for beginners. This simplicity helps new developers start building web applications quickly.
**Wide Adoption and Community Support**:
- PHP has a large and active community. This means extensive documentation, numerous tutorials, and a wealth of online resources. Community support also translates into a vast pre-written code, frameworks, and plugin library.
**Integration Capabilities**:
- PHP integrates seamlessly with various databases (such as MySQL, PostgreSQL, SQLite), web servers (like Apache and Nginx), and other services. This makes it a versatile choice for web development.
**Open Source**:
- PHP is free to use and distribute. This lowers the cost of development, especially for small businesses and startups.
**Cross-Platform Compatibility**:
- PHP can run on multiple platforms, including Windows, Linux, and macOS. This flexibility ensures that PHP applications can be deployed in diverse environments without compatibility issues.
## Demerits Of PHP
Below are a few Demerits of PHP.
1. **Inconsistent Function Naming and Parameter Order**:
- One of the common criticisms of PHP is its inconsistent function naming conventions and parameter order. For example, functions may have different naming patterns (`str_replace` vs. `strpos`) and parameter orders (`array_filter($array, $callback)` vs. `array_map($callback, $array)`). This inconsistency can lead to confusion and errors, especially for new developers.
2. **Historical Security Issues**:
- PHP has had a history of security vulnerabilities, partly due to its widespread use and partly due to the way it was designed. While modern PHP has significantly improved in terms of security features, legacy codebases and bad practices from earlier versions can still pose security risks.
3. **Performance Compared to Other Languages**:
- While PHP has made great strides in improving performance (especially with PHP 7 and later), it can still be slower compared to some other languages like Node.js or Go for certain tasks. This can be a drawback for applications requiring extremely high performance and low latency.
4. **Weak Typing**:
- PHP’s weak typing system, which allows implicit type conversions, can lead to unexpected behavior and bugs that are difficult to track down. For example, comparing a string to a number may yield unexpected results (`"123" == 123` is true, but `"123" === 123` is false). This can be problematic, especially for large, complex codebases.
5. **Over-Reliance on Older, Procedural Code**:
- Many PHP applications and tutorials still use older, procedural programming techniques rather than modern, object-oriented, or functional programming practices. This can lead to less maintainable and harder-to-read code. While modern frameworks encourage better practices, the legacy of procedural code can still be a significant issue.
## What Is React
React JS is a declarative, efficient, and flexible JavaScript library for building user interfaces. It’s ‘V’ in MVC. ReactJS is an open-source, component-based front-end library, responsible only for the view layer of the application. It is maintained by Facebook.
## Merits Of React Js
Below are a few Merits of React Js.
1. **Component-Based Architecture**:
- React follows a component-based architecture, which allows developers to build reusable UI components. This modularity leads to cleaner, more maintainable, and scalable code. Components can be reused across different parts of an application, reducing redundancy and improving development efficiency.
2. **Virtual DOM for Improved Performance**:
- React uses a Virtual DOM (Document Object Model) to optimize rendering performance. When the state of an application changes, React updates the Virtual DOM first, which then efficiently updates the actual DOM only where necessary. This minimizes direct manipulation of the DOM, leading to faster and more efficient updates, particularly beneficial for complex applications with frequent UI changes.
3. **Declarative UI**:
- React's declarative approach to building UIs makes code more predictable and easier to debug. Developers describe what the UI should look like for a given state, and React takes care of updating the actual UI based on state changes. This simplifies the process of developing interactive user interfaces and makes the code more readable.
4. **Rich Ecosystem and Community Support**:
- React has a vast ecosystem with numerous libraries, tools, and extensions that enhance its functionality. The strong community support ensures that developers have access to extensive resources, tutorials, and third-party components. Additionally, the backing of Facebook and contributions from a large number of developers worldwide ensure React remains up-to-date and continuously improving.
5. **Strong Support for JSX**:
- React uses JSX (JavaScript XML), a syntax extension that allows HTML to be written within JavaScript. JSX simplifies the process of creating React components and makes the code more readable by visually separating the structure (HTML) from the logic (JavaScript). This tight integration of markup with logic enhances development efficiency and reduces context switching for developers.
## Demerits Of React Js
Below are a few Demerits of React Js.
1. **Steep Learning Curve**:
- React's flexibility and the wide array of tools and libraries in its ecosystem can make the learning curve steep for beginners. Understanding concepts like JSX, components, state management, and the intricacies of the Virtual DOM can be challenging for new developers.
2. **Boilerplate and Complexity**:
- Setting up a React project often involves considerable boilerplate code and configuration. Tools like Create React App simplify the initial setup, but as projects grow, the complexity can increase, requiring additional configuration and understanding of build tools like Webpack and Babel.
3. **Rapidly Changing Environment**:
- The React ecosystem evolves quickly, with frequent updates and new tools emerging regularly. Keeping up with the latest best practices, updates, and libraries can be overwhelming for developers. This fast pace of change can also lead to issues with outdated documentation and compatibility between different libraries and versions.
4. **Poor SEO**:
- By default, React renders applications on the client side, which can lead to poor SEO performance because search engine crawlers might have difficulty indexing the dynamic content. Although solutions like server-side rendering (SSR) with frameworks like Next.js exist, implementing them adds complexity to the project.
5. **State Management Complexity**:
- Managing state in large React applications can become complex. While React's built-in state management works well for small applications, scaling up requires more sophisticated state management solutions like Redux, MobX, or the Context API. These solutions add another layer of complexity and require additional learning and setup.
##The Synergy Between PHP and React in Modern Web Applications
The synergy between PHP and React in modern web applications leverages the strengths of both technologies to create robust, dynamic, and scalable applications. Here’s an in-depth look at how these technologies complement each other and the benefits of combining them:
## 5 Benefits of using PHP with React
Note: the benefits are more than five but here are the listed few!
## 1. Full-Stack Versatility
**Frontend and backend integration:**
- **Seamless Data Handling:** React effectively manages the front end, while PHP can handle server-side logic and data exchanges, resulting in a coherent development environment.
- **API-Driven Development:** By supplying data to the React frontend via GraphQL or RESTful endpoints, PHP may function as a potent backend API, allowing for a clear division of responsibilities.
**Efficiency of Development:**
- **Parallel Development:** Teams working on front-end and back-end projects simultaneously can speed up development and eliminate bottlenecks.
- **reused Components:** Frontend development is more modular and manageable because of React's component-based design, which guarantees that UI elements are reused.
## 2. Scalability
**Managing a Higher Load:**
- Effective Backend: PHP frameworks like Laravel are designed to manage massive amounts of data and user requests effectively, handling intricate and scalable backend processes.
- Frontend Optimisation: Even with intricate and data-intensive apps, React's virtual DOM and effective diffing technique guarantee quick and responsive UI changes.
**Architecture of Microservices:**
- **Modular Approach:** Different services can scale independently when PHP is included in a microservices architecture. React facilitates scalability by allowing it to use these services as required.
- **Burden Distribution:** The program as a whole can manage more traffic skillfully by dividing the burden between PHP, which handles server-side operations, and React, which handles client-side interactions.
## 3. Performance
**Quick load times:**
- **Server-Side Rendering (SSR):** Initial HTML may be pre-rendered by PHP and sent to the client, thereafter React can hydrate it. This method boosts the user experience and speeds up the initial load time.
- **Asynchronous Data Fetching:** By using React, data may be fetched from the PHP backend asynchronously, maintaining a responsive user interface and effective handling of data changes.
**Enhanced Communication:**
- **Effective State Management:** React's state management features, such as context and hooks, enable better handling of UI state changes, which minimizes the need for pointless re-renders.
- **Caching and Optimisation:** PHP can use server-side caching techniques to speed up the serving of static material and lower database demand, therefore improving performance.
## 4. Rich User Interfaces
**UIs that are interactive and dynamic:**
- **Component-Based design:** React's component-based design enables programmers to create complex, interactive user interfaces that are simple to update and expand.
- **Real-Time Updates:** React is capable of handling dynamic content changes and real-time updates with efficiency, making for a smooth and interesting user experience.
**Improved User Experience:**
- **Contemporary UI Libraries:** React works nicely with contemporary UI libraries and frameworks (such as Material-UI and Ant Design), enabling programmers to design aesthetically pleasing and intuitive user interfaces.
- **Building responsive** and adaptable user interfaces (UIs) that function effectively on a variety of devices and screen sizes is made simple using React.
## 5. SEO-Friendly
**Better Optimisation for Search Engines:**
- **Server-Side Rendering (SSR):** Pre-rendering HTML content using PHP before providing it to the client guarantees better search engine indexing and SEO.
- **Meta Tags and Dynamic material:** Using information from the PHP backend, React can dynamically manage and update meta tags, titles, and other SEO-relevant material.
**Better Crawlability:**
- **Static Site Generation (SSG):** React may produce static pages at build time, improving the application's SEO while retaining PHP for dynamic content, by utilizing solutions like Next.js, which supports both SSR and SSG.
- **URL Structure:** React can handle routing and navigation, making sure that visitors and search engines can explore the site with ease, while PHP can manage clear, SEO-friendly URL structures.
Developers may construct robust, scalable, and performance-optimized online apps with rich user experiences and search engine optimization by integrating PHP with React. Because of their synergy, frontend and backend technologies may be combined to create a strong and adaptable development process.

## **Creating a PHP and React Development Environment**
At this point, we are about to start an actual project using React.js and PHP as the front end.
## Prerequisites
There are things you need to know as a developer or things you need to have to be able to make php work as a backend with React. Here is the essential list!
- Have Basic Knowledge of PHP
- Know your React.Js
- Make Sure Node.js accompanied by npm is installed on your machine.
- Have PHP installed in your system Apache or Nginx
## Step By Step Process On How To Use PHP As a Backend Using React As A Front-end
The step to use PHP as a backend alongside React is quite simple and it’s as follows.
**Building The Frontend**
**Step 1:** Open your terminal and run the following command below:
npx create-react-app my-react-app
Note: before running this command, you have to cd into the directory where you want your react folder to be! the way to cd to your desired directory is by adding this command to your terminal
cd Documents
After this, you’ll wait for your React app to be created.
Step 2: Navigate to your project folder:
The project you just created needs to be visited in the terminal
cd my-react-app
Step 3: Start the development server:
npm start
**Building the PHP Backend**
It's time to construct the PHP backend now that your React application is operational:
**Step 1:** Create a new folder for your PHP files within your React app directory.
to achieve this, run the following command on your terminal
mkdir php_backend
By running this command you’ll see a folder named php_backend
**Step 2:** Inside the php-backend folder, create a file named `index.php`.
Note: you’re free to call it any name, in my case I decided to use the index.php.
**Step 3:** In the `index.php` you can start defining your PHP endpoints and logic.
Below is what is written in my `php-backend/index.php` if you’re a PHP developer you’ll be familiar with this syntax.
<?PHP
$serverName="localhost";
$userName="root";
$password="";
$databaseName="react_php";
$conn = mysqli_connect($serverName, $userName, $password, $databaseName);
$recText = $_POST['text'];
$query = ("INSERT INTO react_php (texts) VALUES('$recText')");
if (mysqli_query($conn, $query)) {
echo "Data has been inserted successfully";
}else {
echo "Error";
}
?>
Now the next thing to do is go to the React Code you created earlier and open the folder in your code editor you’ll see a folder like `src/App.js` and add this syntax below.
import React, { Component } from 'react';
// import logo from './logo.svg';
import axios from 'axios'; //Import Axios
import './App.css';
class App extends Component{
state = {
text : ""
}
handleAdd = async e =>{
await this.setState({
text : e.target.value
})
}
handleSubmit = e =>{
e.preventDefault();
console.log(this.state.text);
let formData = new FormData();
formData.append("text", this.state.text);
const url = "http://localhost:80/react-backend/"
axios.post(url,formData)
.then(res=> console.log(res.data))
.catch(err=> console.log(err))
}
render(){
return(
<div className="App-header">
<input
onChange={this.handleAdd}
className="form-control"
// value={this.state.text}
type="text"
id='text'
placeholder='Enter Some Text!'/>
<br/>
<button
onClick={this.handleSubmit}
className="btn btn-success"
id='submit'> Save</button>
</div>
);
}
}
export default App;
Note: what allows the PHP to work is the `**Axios**.` Look at the code snippet below you’ll see how we used it!
In the public folder of your project, you’ll see an `index.html` file in that file I added a bootstrap cdn as a framework I'm using,
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@4.6.2/dist/css/bootstrap.min.css">
So Here’s a little styling.
.App {
text-align: center;
}
.App-logo {
height: 40vmin;
pointer-events: none;
}
@media (prefers-reduced-motion: no-preference) {
.App-logo {
animation: App-logo-spin infinite 20s linear;
}
}
.App-header {
background-color: #282c34;
min-height: 100vh;
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
font-size: calc(10px + 2vmin);
color: white;
}
.App-link {
color: #61dafb;
}
@keyframes App-logo-spin {
from {
transform: rotate(0deg);
}
to {
transform: rotate(360deg);
}
}
After trying all these here’s the view it will give to you.
Her is the database controlling the backend. once you fill in the text and click save the text will display in the database automatically.
hereafter I wrote `**Freddie**` and I clicked on **Browse,** in the top right corner of the image displayed below. Once you see this know that you have done the right thing.
That’s the step I used in React and PHP in a single application.
## Conclusion
In conclusion, integrating PHP as a backend with React as a frontend offers a robust and versatile solution for modern web application development. As discussed, this combination leverages the strengths of PHP's server-side capabilities and React's dynamic, component-based architecture to create scalable, high-performance applications. PHP efficiently handles server-side logic, database interactions, and API creation, while React ensures a rich, responsive user interface and seamless data handling.
This synergy between PHP and React not only enhances the development process but also results in web applications that are interactive, engaging, and SEO-friendly. Embracing this powerful integration empowers developers to build comprehensive and user-centric web applications with ease and efficiency.
I hope you found this tutorial incredibly valuable! Until next time, goodbye.

1,917,144 | Designing B2B Authentication Experiences: Universal vs. Organization-Specific Login | One of the first decisions you must make when architecting a new B2B application? How you’re going to... | 0 | 2024-07-09T10:35:04 | https://www.scalekit.com/blog/designing-b2b-authentication-experiences-universal-vs-organization-specific-login | webdev, tutorial, security, saas | One of the first decisions you must make when architecting a new B2B application? How you’re going to allow users to authenticate.
You have two choices: the universal login page or the organization-specific login page. We’ll make the distinction clear in a moment, but for now, know that the path you choose here has significant downstream effects on the entire lifecycle of your B2B application, and in ways far more significant than designing and developing a login page that looks good. Notably, three personas are most affected with the choice you make:
- Your internal product engineers, who build your application.
- Your customers’ IT administrators, who provision users, manage privileges, and enable single sign-on (SSO) integration with their identity providers (IdPs) such as Okta, Microsoft Azure AD.
- Your product’s users, who will be logging into your application.
Conveniently, two popular applications—Notion and Slack—have made opposite choices for end-user authentication flows. Their ubiquity makes them ideal for identifying how they implemented differing flows, tracing the pros and cons for each affected persona, and ultimately helping you create the best authentication paradigm for your application.
## What are the Notion and Slack styles of Authentication?
Before diving too deeply into authentication nuances, let’s clarify our definitions.
- Notion-style authentication flow uses universal login page
- Slack-style authentication flow uses organization-specific login page
### How are they different?
With a universal login page, the application identifies which organization the end user belongs to. In contrast, with an organization-specific page, the end user shares the organization as input to the application before they can be authenticated.
With Notion, you start authentication by loading the universal login page at notion.so/login. You give your work email address, which Notion uses to identify which organization you belong to based on the domain name. If your email is celina@foocorp.com, Notion assumes you’re part of the organization associated with foocorp.com.
Notion uses that information to provide you with the next best step for the authentication flow, which might be entering a password, using SSO, receiving a magic link, or any auth setting configured by your IT admin.
In the case of Slack’s authentication experience, as an end user, you must navigate to the Slack’s organization-specific login page at a specific URL, like foocorp.slack.com. In this case, you’ve already specified which organization you belong to (Foocorp) through the subdomain, and Slack uses that information to show you the appropriate authentication flow.
In both cases, once the application identifies the end-user’s organization, it honors their authentication settings, including SSO, identity provider, multi-factor authentication (MFA), password policy, and so on.
The user experience (UX) around honoring those settings can still vary between applications. Notion’s universal login page, for example, separates the email and password fields so it can perform the home realm discovery (that’s discovering the tenant) and honor auth settings.
Note that, Dropbox hides the password field if the email address entered matches a tenant with enterprise authentication enabled.
Freshworks takes yet another approach, using home realm discovery to ascertain your tenant and redirecting your browser to an organization-specific login page.
Again, these differences might seem small, but the impact is outsized by a few orders of magnitude by the resulting choices around implementation and infrastructure.
### Contributing technical factors: tenancy and home realm discovery
Tenancy is the architectural decision to isolate the authentication policies, settings, users, and data between each organization registered with an application. Multi-tenant architecture is an essential ingredient for the authentication and security of a SaaS app, ensuring a user of organization Foorcorp can never read data belonging to organization Barcorp.
Home realm discovery (HRD) is the process by which a application identifies which tenant a user belongs to from the login page. Because every application uses a multi-tenant architecture, HRD is also necessary, as there could be a hundred Celina users, each belonging to a different organization and stored inside a different tenant. HRD requires an identifier, which applications collect in a few standard ways:
- The domain name (foocorp.com) on the end-user’s work email.
- An organization-specific “username,” like Foocorp.
- A user-specific ID that cannot be repeated elsewhere, like celina0001 versus celina0002.
If we map this idea to the universal and organization-specific login pages concept from before, we can clarify our definitions even more.
- With a universal login page, the application must complete some type of HRD to authenticate end users.
- With an organization-specific login page, the HRD is done as the user inputs the organization name as part of the authentication process.
Once the application completes HRD and maps the end user’s identifier to a tenant, it can honor those authentication settings and allow them to finish logging in using approved methods. Now that you understand the two possible authentication flows for a application, and how each works alongside your required multi-tenant architecture, we can explore those big implications.
### For your app’s internal engineering team
**Universal Login**
Pros
- Universal login pages are easy to design and develop, as only one possible user interface (UI) and common UX pattern exists.
- You can extend universal login pages to allow a single user to log in to multiple workspaces for cross-organization collaboration similar to Notion.
Cons
- Your team must implement a robust Home Realm Discovery (HRD) to discover the appropriate tenant that a user belongs to based on the user input. This Home Realm Discovery can either based on user’s email address of explicit input of user’s tenant information like Account Name, Organization ID etc. This requires additional engineering effort for the HRD implementation.
- If your customers require data residency, you must engineer more network-level workarounds to redirect users to the appropriate tenant and region.
**Organization-specific Login**
Pros
- Users perform HRD on your behalf by supplying the subdomain, which simplifies your backend logic.
- In some ways, it’s easier for your team to manage data residency, as you can map the DNS records for a specific tenant (foocorp.com) to cloud resources in their region of choice.
Cons
- Instead of designing and developing a single authentication flow, your team is now responsible for many.
- Must develop additional measures to help new users remember the URL for their login page, such as email reminders. You may even want to create a method for them to recover a “lost” organization.
### For your customer’s IT administrator
**Universal login**
Pros
- Similar to the development process, they only have a single authentication flow and login page to worry about.
Cons
- IT administrators at enterprise organizations might require far more customization than a universal login page can offer.
**Organization-specific login**
Pros
- Customize the login page so their users perceive the product as a white-labeled solution.
- Restrict authentication methods to only an approved subset of the available options, simplifying the UX and moving users toward the “best” option.
- Add custom terms or disclaimer notices onto the login page for legal or compliance purposes.
Cons
- Must educate their employees or customers to visit the specific URL to access the application.
### For your application’s end user
**Universal login**
Pros
- The UX is extremely straightforward: they navigate to a well-known URL like notion.so/login or through a big Log in button on your homepage.
Cons
- None.
**Organization-specific login**
Pros
- The UX around approved authentication methods
Cons
- End users must remember the URL for their organization-specific login page. If they can’t remember or retrieve the information, they could be frustrated enough to create a new account or abandon your application altogether.
## How do you choose between a universal vs. organization-specific login page?
Frankly, there is no direct answer. The best solution is based on your customers and admins experience in your application. As you’re making other architectural and technical decisions, such as which JavaScript UI framework to choose, whether to build a monolith or many microservices, or which cloud provider gives you the most startup credits, you should take time to weigh the user experience for each persona in light of your long-term go-to-market (GTM) strategy.
Generally, if you’re appealing to the end-user experience, universal login pages are most familiar to the widest range of users. If you need to offer the customer IT administrator complete flexibility, or are selling to enterprise customers who expect a completely white-labeled solution, then organization-specific pages are a great fit.
What type of login page did Scalekit pick? When we reach general availability, we’ll use a universal login page, where our application performs HRD using the user’s work email as the identifier.
We opted for the universal login page to ensure our users always have the simplest possible experience logging in. We don’t want situations where users have lost their accounts simply because they forgot which subdomain they’re supposed to navigate to. We know that comes at a higher technical cost to us around HRD, but it’s a sacrifice we’re willing to make for the most seamless end-user experience.
The other decision you must make early on is how you’ll build the authentication integration itself. You can go it alone and build a [SAML implementation](https://www.scalekit.com/blog/read-this-before-you-implement-saml) for ultimate control at the cost of complexity and many developer hours, or you can partner with a platform like [Scalekit](https://www.scalekit.com/) to get your B2B application enterprise-ready in days, not weeks or months.
Either way, ensure your choice lets you also pick the login page that works best for your customers—once you’ve started developing and deploying infrastructure, you can’t take your choice back. | scalekit |
