1,891,199 | Why the R1 Rabbit OS Device Isn't Worth the Hype | The debut of the R1 device promised a revolutionary gadget that could understand its owner and... | 0 | 2024-06-17T12:39:41 | https://dev.to/lilarmstrong/why-the-r1-rabbit-os-device-isnt-worth-the-hype-246i | rabbitos, technology, ai, computing |
The debut of the R1 device promised a revolutionary gadget that could understand its owner and automate mundane visual tasks, a feature touted as a significant leap in mobile technology. When I pre-ordered the R1 device in January 2024, I had high expectations, fuelled by the considerable hype surrounding it. However, after receiving my order in June 2024, I found myself disappointed as the device fell short of my expectations. Below, I highlight key reasons why the Rabbit R1 device may not be the best choice for everyone, hoping to aid you in making an informed purchasing decision.
### Limited Conversation Duration
Activating the voice prompt on the R1 device involves pressing and holding a button on the right-hand side. While this seems straightforward, the dual-purpose nature of this button—as both a voice activation and power button—results in a frustratingly short conversation window. Hold the button too long, and the device powers off, cutting off your interaction. Though there is an option to use an on-screen keyboard and images to communicate with the AI, this defeats the purpose of the device, as these tasks can be performed just as easily on a standard mobile device.
### Limited App Connections
The R1 connects to apps like Spotify through its Large Action Model (LAM), which Rabbit describes as a method for the device to navigate and perform actions within apps based on user requests. This innovation aims to make the R1 more than just an information retrieval tool. However, the device currently supports only four apps: Uber for food, Spotify, DoorDash, and MidJourney. While Rabbit promises the ability to teach the device to use any app, the current limited app support significantly diminishes its value.
### Device Color
Color plays a significant role in user experience, influencing emotions and behavior. The R1 device comes in red, a color that, while impactful, is not ideal for prolonged and diverse use due to its stimulating effects. Colors that promote calmness and clarity, such as blues and greens, would have been more appropriate, enhancing focus and comfort. While I was willing to overlook this in hopes that the device’s other benefits would outweigh my concerns, it unfortunately did not.
### AI Issues
The AI in the R1 device is far from novel. There are instances where the AI fails to respond or leaves the user clueless about ongoing processes. This often happens when the AI doesn’t understand the context or specific words. Although the device sometimes indicates when it hasn’t understood a query, there are many occasions where no feedback is provided, leading to a poor user experience. Additionally, the R1 lacks GPS and navigation capabilities and performs basic tasks like setting reminders and sending emails poorly. The necessity of being online 24/7 to use the R1 is another significant drawback.
### Poor Battery Life
The R1 device’s battery life is unimpressive. For a device primarily using voice prompts, I expected a longer battery life. However, I found that the battery depletes quickly even when the device is idle. For instance, after leaving the device unused overnight, it was completely drained by the next morning despite starting at 100% charge.
### No USB Charging Cable
Another disappointing aspect was the lack of a USB charger and cable in the package. While this might have been a trade-off for a cheaper device, including a charger, even at an additional cost, would have been more user-friendly and cost-effective for the end user.
### Confusing User Interface
The R1 device’s user interface is confusing and not user-friendly. The lack of a comprehensive user manual exacerbates this issue, leading to a frustrating user experience. The interfaces introduced by the R1 team are not intuitive, making navigation and usage more complicated than necessary.
---
In summary, while the R1 Rabbit OS device promised innovation, it falls short in several critical areas. Its limited conversation duration, poor app connectivity, unsuitable color choice, unreliable AI performance, lack of basic features, inadequate battery life, absence of essential accessories, and confusing user interface collectively contribute to a disappointing user experience. Potential buyers should carefully consider these drawbacks before purchasing the R1 device. The r1 device seems futuristic, but in my own honest opinion, it isn’t worth your time. Life with the r1 should be awesome, but it is a mess. | lilarmstrong |

1,891,202 | Advanced Go Concepts | Data Structures Arrays and Slices Arrays Arrays in Go are... | 0 | 2024-06-17T12:44:46 | https://dev.to/gophers_kisumu/advanced-go-concepts-28o4 | ## Data Structures
### Arrays and Slices
#### Arrays
Arrays in Go are fixed-length sequences of elements of the same type. They are defined with a specific size, and once created, their size cannot be changed.
```go
var a [5]int // array of 5 integers
```
Arrays are useful when the size of the data is known and fixed, but their static nature makes them less flexible.
#### Slices
Slices are more flexible than arrays and are the preferred data structure in Go for handling sequences of elements. A slice is a dynamically-sized, flexible view into the elements of an array.
```go
s := []int{1, 2, 3, 4, 5} // slice of integers
```
Slices provide powerful and convenient ways to work with sequences of data. They support automatic resizing and share the underlying array storage, making them memory-efficient.
### Maps
Maps are Go's built-in hash table implementation and are used to store key-value pairs. They provide fast lookups, additions, and deletions.
```go
m := make(map[string]int)
m["foo"] = 42
```
Maps are ideal for scenarios where you need to associate unique keys with values, such as dictionaries, caches, and lookup tables.
### Structs
Structs are composite data types that group together variables under a single name. Each variable in a struct is called a field, and they can be of different types.
```go
type Person struct {
Name string
Age int
}
```
Structs are the building blocks of data structures in Go and are used to create complex types that group related data together.
### Pointers
#### Understanding Pointers
Pointers hold the memory address of a value. They are used to reference or dereference variables, allowing for indirect manipulation of values.
```go
var p *int
i := 42
p = &i // p now holds the memory address of i
```
Pointers are crucial for dynamic data structures, performance optimization, and when you need to share data between functions.
#### Pointer Operations
- **Dereferencing:** Access the value at the memory address held by a pointer using the `*` operator.
```go
fmt.Println(*p) // prints the value of i, which is 42
```
- **Address-of:** Get the memory address of a variable using the `&` operator.
```go
p = &i // p now holds the address of i
```
#### Structs with Pointers
Pointers can be used with structs to reference and manipulate data without copying the entire struct.
```go
type Person struct {
Name string
Age int
}
p := &Person{"Alice", 30}
p.Age = 31 // modify the Age field through the pointer
```
Using pointers with structs allows for more efficient memory usage and direct manipulation of the original data.
## Methods and Interfaces
### Defining Methods
Methods are functions with a special receiver argument. They can be defined for any type (except pointer types) and allow you to associate behaviors with types.
```go
type Circle struct {
Radius float64
}
func (c Circle) Area() float64 {
return 3.14 * c.Radius * c.Radius
}
```
In the example above, the `Area` method is defined for the `Circle` type, allowing instances of `Circle` to calculate their area.
### Receiver Functions
Receiver functions are methods that operate on the receiver, which is a special parameter between the `func` keyword and the method name. Receivers can be value receivers or pointer receivers.
- **Value Receiver:** The method operates on a copy of the value.
```go
func (c Circle) Area() float64 {
return 3.14 * c.Radius * c.Radius
}
```
- **Pointer Receiver:** The method operates on the original value through a pointer.
```go
func (c *Circle) Scale(factor float64) {
c.Radius *= factor
}
```
Using pointer receivers allows methods to modify the original value and is more efficient for large structs.
### Understanding and Using Interfaces
Interfaces define a set of method signatures and are satisfied by any type that implements those methods. They provide a way to specify the behavior that types must have.
```go
type Shape interface {
Area() float64
Perimeter() float64
}
```
Interfaces enable polymorphism in Go, allowing you to write flexible and reusable code.
#### Example Usage of Interfaces
```go
type Rectangle struct {
Width, Height float64
}
func (r Rectangle) Area() float64 {
return r.Width * r.Height
}
func (r Rectangle) Perimeter() float64 {
return 2 * (r.Width + r.Height)
}
func PrintShapeInfo(s Shape) {
fmt.Println("Area:", s.Area())
fmt.Println("Perimeter:", s.Perimeter())
}
r := Rectangle{Width: 3, Height: 4}
PrintShapeInfo(r)
```
In this example, the `Rectangle` type implements the `Shape` interface by providing the `Area` and `Perimeter` methods. The `PrintShapeInfo` function can accept any type that satisfies the `Shape` interface, demonstrating the power and flexibility of interfaces in Go. | gophers_kisumu | |

1,891,135 | How to Build Progressive Web Apps (PWAs) Using Laravel? | Ever feel like your website could be more? We've all been there. Users today expect fast, reliable... | 0 | 2024-06-17T12:36:59 | https://dev.to/aaronreddix/how-to-build-progressive-web-apps-pwas-using-laravel-1f6o | webdev, pwa, beginners, laravel | Ever feel like your website could be more? We've all been there. Users today expect fast, reliable experiences, even when their internet connection isn't perfect.
PWAs are the future of web development, blurring the lines between websites and mobile apps. They offer the best of both worlds: the accessibility of a website and the functionality of a native app. Imagine a website that loads instantly, even offline, lets you send push notifications, and feels like a native app on your phone's home screen. That's the magic of PWAs!
But building a PWA from scratch can be daunting. Here's where Laravel, a powerful PHP framework, swoops in to save the day. Laravel's robust framework, with its features like routing, templating, and caching, is a perfect fit for building powerful PWAs. Plus, Laravel's awesome community and available PWA packages make development a breeze.
So, are you ready to take your web development skills to the next level and build amazing PWAs? Let's dive in and explore how Laravel can help us create next-gen web experiences!
## What are PWAs?
Imagine you're browsing your favorite online store on your phone. Suddenly, the internet cuts out. Normally, you'd be stuck staring at a dreaded "loading" message. But with a PWA (Progressive Web App), things are different!
[PWAs are essentially websites that act like native apps](https://digimonksolutions.com/pwa-vs-native-app/). They offer features you wouldn't normally expect from a website, like:
**1. Offline Functionality**: Even without an internet connection, a PWA can still display cached content and let you interact with some features. This makes them perfect for situations with spotty internet. This is primarily achieved through Service Workers, which cache resources and handle network requests.
**2. Push Notifications**: Just like mobile apps, PWAs can send you updates and alerts directly to your device, keeping you in the loop. This typically requires integrating with services like Firebase Cloud Messaging (FCM).
**3. Installable on Your Home Screen**: No more hunting through bookmarks! PWAs can be installed directly on your home screen, just like a native app. With a single tap, you're ready to go. This is enabled by the web app manifest and the Service Worker.
Think of Twitter Lite or the Spotify web app – these are both examples of PWAs in action. They offer a smooth, app-like experience without requiring you to download anything from an app store.
## Why Use Laravel for PWAs?
So, PWAs sound pretty awesome, but why use Laravel to build them? Here's the thing: Laravel is like a Swiss Army Knife for web development. It comes packed with features that make building PWAs efficient and enjoyable.
Here's how Laravel streamlines the PWA development process:
- **Built-in Features**: Laravel already has features like routing, templating, and caching that are crucial for any web application, including PWAs. This saves you time and effort compared to building everything from scratch. It also supports robust RESTful APIs, which are often used in PWAs for dynamic content.
- **Blade Templating**: Laravel's Blade templating engine makes it easy to structure your PWA's views and keep your code clean and organized. Think of Blade as a cheat sheet for writing beautiful and efficient HTML code. Blade’s components and directives help in building reusable and maintainable front-end components.
- **Asset Management**: Managing all the different files (JavaScript, CSS, images) that go into a PWA can be a headache. Laravel's asset management features, including Laravel Mix, help you keep things organized and ensure all your files are properly referenced in your application.
- **Community to the Rescue**: The Laravel community is massive and incredibly helpful. There's a wealth of resources available online, and you're never far from finding an answer to your PWA development questions.
- **Packages**: There are several PWA packages available that can simplify the process even further. These packages often handle things like Service Worker generation and Manifest creation, saving you valuable development time.
In short, Laravel provides a solid foundation and a supportive community to help you build amazing PWAs efficiently. It's like having a superhero sidekick for your PWA development journey!

## Step 1: Project Setup
There are two ways to tackle this:
### 1. New Laravel Project
If you're starting fresh, you can create a brand new Laravel project using the Laravel installer. This can be done from your terminal with the following command:
```
composer create-project --prefer-dist laravel/laravel your-project-name
```
Make sure you replace "your-project-name" with something awesome and descriptive!
### 2. Existing Laravel Project
If you already have a Laravel project you'd like to turn into a PWA, that works too! Just navigate to your project directory in your terminal using:
```
cd your-existing-project
```
### Environment Check
No matter which approach you took, make sure you have the following things set up on your development machine:
- **PHP**: PWAs rely on PHP to run server-side logic. Make sure you have a recent version of PHP (7.3 or higher) installed on your machine. You can check your version by running php -v in your terminal.
- **Composer**: Composer is a dependency manager for PHP that helps us install Laravel and other [necessary Laravel packages](https://medium.com/codex/top-10-laravel-packages-for-developers-in-2024-c19432ca4d67). You can find installation instructions on the Composer website.
Once you have these things squared away, you're ready to dive into the exciting world of [PWA development with Laravel](https://digimonksolutions.com/services/laravel-development/)!
## Step 2: Package Installation
Remember how we mentioned awesome PWA packages for Laravel that can simplify our lives? Well, now's the time to put them to good use!
### 1. Package Power
Laravel is all about leveraging packages to extend functionality. In the world of PWAs, a popular choice is the "[Laravel PWA](https://github.com/silviolleite/laravel-pwa)" package by Silvio Leite. This package offers a convenient way to configure and generate essential PWA elements, like the Service Worker and web app manifest.
### 2. Installation with Composer
To install the "Laravel PWA" package, navigate to your project directory in your terminal and run the following command:
```
composer require silviolleite/laravel-pwa
```
This tells Composer to download and install the "Laravel PWA" package, along with any other dependencies it might have.
### 3. Keeping it Tidy
Once the package is installed, we can optionally publish its configuration file using the following command:
```
php artisan vendor:publish --provider="LaravelPWA\Providers\LaravelPWAServiceProvider"
```
This will create a new configuration file (config/laravelpwa.php) where you can customize various aspects of your PWA, such as app icons, theme colors, and manifest details. We'll explore this configuration file in more detail later.
By installing the "Laravel PWA" package, we've taken a big step towards building a powerful PWA. These packages handle a lot of the heavy lifting for us, allowing us to focus on the core functionalities of our application.
## Step 3: Service Worker Magic
Service Workers are like the silent heroes of the PWA world. These scripts run in the background, separate from your web page, and hold immense power:
### 1. Caching Resources
Service Workers can intercept requests for resources (like JavaScript files, images) and store them locally. This means that when a user visits your PWA again, even offline, the Service Worker can retrieve those cached resources and display a basic version of your app.
### 2. Handling Offline Requests
If a user tries to access a part of your PWA that requires an internet connection while offline, the Service Worker can gracefully handle the request and potentially display a fallback message or cached content.
### 3. Don’t Worry About the Code (For Now):
The good news is that the "Laravel PWA" package we installed earlier can simplify Service Worker generation. It typically provides a configuration option where you can specify which files and routes you want the Service Worker to cache. The package then handles the creation of the Service Worker script with the necessary caching logic.
### A Glimpse Under the Hood
For those curious about the inner workings, Service Workers are written in JavaScript and utilize features like the Cache API and the Fetch API. They can also leverage libraries like Workbox for more advanced caching strategies. But for now, let's focus on leveraging the power of the "Laravel PWA" package to streamline Service Worker implementation.
Here's a basic example of a Service Worker script:
```
self.addEventListener('install', event => {
event.waitUntil(
caches.open('my-cache')
.then(cache => cache.addAll([
'/',
'/css/app.css',
'/js/app.js',
// other assets
]))
);
});
self.addEventListener('fetch', event => {
event.respondWith(
caches.match(event.request)
.then(response => response || fetch(event.request))
);
});
```
## Step 4: PWA Manifest: App Identity
Imagine your PWA as a superhero. Just like a superhero needs a cool costume and a catchy name, your PWA needs a PWA Manifest – a JSON file that acts as your app's identity card. The Manifest tells the browser and user all sorts of important things about your PWA, such as:
- **App Name**: This is the name that will be displayed on the user's home screen and in app launcher menus.
- **Icons**: The Manifest specifies different sized icons for your PWA, ensuring it looks sharp on all devices.
- **Theme Color**: This sets the dominant color for your PWA's user interface, creating a cohesive look and feel.
- **Start URL**: This defines the starting point (the main page) of your PWA when launched from the home screen.
### The Manifest in Action
Let's take a closer look at what a Manifest file might look like:
```
{
"name": "My Awesome PWA",
"short_name": "My PWA",
"start_url": "/",
"display": "standalone",
"theme_color": "#007bff",
"background_color": "#ffffff",
"icons": [
{
"src": "/images/icons/icon-72x72.png",
"sizes": "72x72",
"type": "image/png"
},
{
"src": "/images/icons/icon-96x96.png",
"sizes": "96x96",
"type": "image/png"
},
// additional icon sizes...
]
}
```
In this example, we have a PWA named "My Awesome PWA" with a short name of "My PWA". It starts at the root URL ("/"), displays in standalone mode (like a native app), and has a theme color of #007bff (a nice blue). The icons array includes different sized icons for various devices.
## Step 5: Offline Views and User Experience
One of the most powerful features of a PWA is its ability to provide a seamless user experience, even when the internet connection is spotty or non-existent. Let's dive into how we can ensure our users have a smooth experience regardless of their connectivity status.
### Informative Messages
First, let's create a custom offline view that informs users they're offline and provides some helpful information. This view can be created using Laravel's Blade templating engine.
### 1. Create an Offline Route
In your routes/web.php file, add a route for the offline view:
```
Route::get('/offline', function () {
return view('offline');
});
```
### 2. Blade Template for Offline View
Create a new Blade template for the offline view. This template will be displayed when users try to access your PWA while offline.
```
<!-- resources/views/offline.blade.php -->
<!DOCTYPE html>
<html>
<head>
<title>Offline</title>
</head>
<body>
<h1>You are currently offline</h1>
<p>Some features may not be available.</p>
</body>
</html>
```
### 3. Service Worker Logic
Ensure your Service Worker serves this offline view when the user is offline. You can modify your Service Worker script to include a fallback response:
```
self.addEventListener('fetch', event => {
event.respondWith(
fetch(event.request).catch(() => caches.match('/offline'))
);
});
```
By implementing an offline view, we provide a better user experience and let users know they're offline in a friendly and informative way.
## Step 6: Deployment and Testing
Building a PWA is an exciting journey, but it's essential to ensure everything works perfectly before going live. Let's explore some best practices for deploying and testing your PWA.
### Thorough Testing
- **Lighthouse Audit**: One of the most effective ways to test your PWA is by running a Lighthouse audit in Chrome DevTools. Lighthouse provides insights into performance, accessibility, and PWA compliance. Here's how you can run a Lighthouse audit:
> 1. Open your PWA in Google Chrome.
> 2. Right-click on the page and select "Inspect" to open Chrome DevTools.
> 3. Navigate to the "Lighthouse" tab.
> 4. Click "Generate report" to run the audit and review the results.
- **Real-World Testing**: It's crucial to test your PWA on multiple devices and network conditions. Try using tools like BrowserStack to test on different devices and simulate various network speeds. This will help you ensure your PWA performs well in real-world scenarios.
- **User Feedback**: Engage with a small group of users to gather feedback on the PWA experience. Pay attention to any issues they encounter and make necessary improvements.
### Best Practices for Deployment
- **HTTPS**: Ensure your PWA is served over HTTPS. Service Workers require a secure context to function correctly. If your site isn't already using HTTPS, consider obtaining an SSL certificate.
- **Server Configuration**: Configure your server to serve the Service Worker and web app manifest files with the correct MIME types. This ensures browsers recognize and handle these files correctly.
- **Continuous Monitoring**: After deployment, keep an eye on your PWA's performance and user feedback. Regularly update and optimize your PWA to maintain a top-notch user experience.
## Conclusion
Building a PWA with Laravel is a rewarding experience that opens up new possibilities for your web applications. By leveraging Laravel's powerful features and the flexibility of PWAs, you can create fast, reliable, and engaging experiences for your users.
Remember, the journey doesn't end here. Stay updated with the latest trends and best practices in PWA development. Explore advanced features like background sync and advanced caching strategies to take your PWA to the next level.
Happy coding, and may your PWAs be ever fast and reliable! | aaronreddix |

1,891,144 | Go Fundamentals | Basic Syntax and Structure 1. Go Program Structure A Go program typically consists of... | 0 | 2024-06-17T12:34:01 | https://dev.to/gophers_kisumu/go-fundamentals-1e7i | #### Basic Syntax and Structure
**1. Go Program Structure**
A Go program typically consists of multiple packages, and the main package serves as the entry point of the program. The basic structure of a Go program is:
```go
package main
import "fmt"
// main function - the entry point of the program
func main() {
fmt.Println("Hello, World!")
}
```
- **Package Declaration**: Every Go file begins with a `package` declaration. The `main` package is special because it defines a standalone executable program.
- **Import Statements**: The `import` keyword is used to include other packages. For example, `fmt` is a package for formatted I/O operations.
- **Function Definition**: Functions are defined using the `func` keyword. The `main` function is the entry point of the program.
**2. Variables and Constants**
Variables and constants are fundamental to any programming language, allowing the storage and manipulation of data.
- **Variables**:
- Declared using the `var` keyword.
- Can be initialized when declared, or later.
```go
var x int
var y int = 10
z := 20 // shorthand for declaring and initializing a variable
```
- **Constants**:
- Declared using the `const` keyword.
- Cannot be changed once initialized.
```go
const Pi = 3.14
const Greeting = "Hello, World!"
```
**3. Basic Data Types**
Go has several built-in data types:
- **Strings**: Represent a sequence of characters.
```go
var name string = "Gopher"
```
- **Integers**: Represent whole numbers.
```go
var age int = 25
```
- **Floats**: Represent floating-point numbers.
```go
var height float64 = 5.9
```
- **Booleans**: Represent true or false values.
```go
var isActive bool = true
```
---
#### Control Structures
**1. Conditionals**
- **If Statement**: Executes a block of code if a specified condition is true.
```go
if x > 10 {
fmt.Println("x is greater than 10")
}
```
- **If-Else Statement**: Provides an alternative block of code if the condition is false.
```go
if x > 10 {
fmt.Println("x is greater than 10")
} else {
fmt.Println("x is 10 or less")
}
```
- **If-Else If-Else Statement**: Checks multiple conditions sequentially.
```go
if x > 10 {
fmt.Println("x is greater than 10")
} else if x == 10 {
fmt.Println("x is exactly 10")
} else {
fmt.Println("x is less than 10")
}
```
- **Switch Statement**: An alternative to multiple if-else if statements, providing a cleaner syntax.
```go
switch day {
case "Monday":
fmt.Println("Start of the work week")
case "Friday":
fmt.Println("End of the work week")
default:
fmt.Println("It's a regular day")
}
```
**2. Loops**
- **For Loop**: The only looping construct in Go, but it can be used in various forms.
- Traditional For Loop:
```go
for i := 0; i < 10; i++ {
fmt.Println(i)
}
```
- While-Like Loop:
```go
i := 0
for i < 10 {
fmt.Println(i)
i++
}
```
- Infinite Loop:
```go
for {
fmt.Println("Infinite loop")
}
```
---
#### Functions
**1. Defining and Calling Functions**
Functions in Go are defined using the `func` keyword. They can have parameters and return values.
- **Basic Function**:
```go
func greet() {
fmt.Println("Hello, World!")
}
func main() {
greet()
}
```
- **Function with Parameters**:
```go
func add(a int, b int) int {
return a + b
}
func main() {
sum := add(5, 7)
fmt.Println(sum)
}
```
- **Function with Multiple Return Values**:
```go
func divide(a int, b int) (int, int) {
quotient := a / b
remainder := a % b
return quotient, remainder
}
func main() {
q, r := divide(10, 3)
fmt.Println("Quotient:", q, "Remainder:", r)
}
```
**2. Anonymous Functions and Closures**
- **Anonymous Functions**: Functions without a name, often used as literals.
```go
func main() {
func() {
fmt.Println("Anonymous function")
}()
}
```
- **Closures**: Anonymous functions that capture variables from their surrounding scope.
```go
func main() {
x := 10
increment := func() int {
x++
return x
}
fmt.Println(increment()) // Output: 11
fmt.Println(increment()) // Output: 12
}
```
By mastering these fundamental aspects of Go, you'll be well-equipped to handle more advanced topics and build robust applications. The simplicity and clarity of Go's syntax and structures make it an excellent choice for both new and experienced developers. | gophers_kisumu | |

```
## Create a New C# Project
First, let's create a new C# Blazor project. Open your terminal and run the following commands:
```bash
dotnet new blazorwasm -o NameOfYourProject
```
This will create a new Blazor project in a directory named NameOfYourProject.
The directory contains by default an example project for you to play around.
To get into more details read this tutorial from the official microsoft website: https://dotnet.microsoft.com/en-us/learn/aspnet/blazor-tutorial/intro
To run the project locally navigate into the project folder:
```bash
cd NameOfYourProject
```
Use this command to start up the local development server:
```bash
dotnet watch
```
It even has hot reloading!
## Build your Project for Deployment
To deploy your C# application to Vercel, you need to build it first on your machine.
Use this command to generate the output files.
```bash
dotnet publish -c Release
```
The output files will be located in this folder:
```bash
bin/Release/net8.0/publish/wwwroot
```
Please note that the exact path my vary a bit. Depending on your .NET version.
## Initialize a Git Repository
Next, initialize a new Git repository and commit your code:
```bash
git init
git add .
git commit -m "Initial commit"
```
No push the code to your git repository.
First connect the github repo to your local repository:
```bash
git remote add origin https://github.comXXXXX
git push origin master
```
## Deploy to Vercel
Now, it’s time to deploy your application to Vercel. Follow these steps:
1. Go to [Vercel](https://vercel.com)
2. Add New Project
3. Select the repository from your github account
4. Set custom Build & Development Settings
5. Override the Output Directory to: *bin/Release/net8.0/publish/wwwroot*
Thats it!
You should now see a preview of your deployed C# Blazor App.
If you want to publish changes follow these instructions:
1. ```bash dotnet publish -c Release```
2. ```git add . && git commit -m "Your Commit Message"```
3. ```git push origin master```
Vercel will take care of the rest and you should see the live changes in 1-2 minutes on your website.
## Final Thoughts
Deploying C# applications to Vercel may seem unconventional given its JavaScript-centric nature. Vercel’s powerful platform allows you to build and ship your C# Blazor applications faster than ever.
By following the steps outlined above, you can harness the power of Vercel for your C# projects, ensuring smooth deployments and high performance. So, gear up, start building, and ship your applications faster with Vercel!

1,891,195 | How template method can ruin your Java code | Author: Konstantin Volohovsky OOP is wonderful. Programmers usually criticize those who don't follow... | 0 | 2024-06-17T12:30:49 | https://dev.to/anogneva/how-template-method-can-ruin-your-java-code-48ni | java, programming, coding | Author: Konstantin Volohovsky
OOP is wonderful\. Programmers usually criticize those who don't follow this paradigm, while the knowledge of patterns is often a must\. However, even the right approach doesn't completely protect from errors\. Today, we'll learn how to break a program using the standard template method\.
## Introduction
This is another article born from the check of [DBeaver](https://github.com/dbeaver/dbeaver) 24 using the PVS\-Studio static analyzer\. Along the way, I found some suspicious code fragments\. They inspired me to devote separate articles to them\. Here's an updatable list of articles in the series:
* [Volatile, DCL, and synchronization pitfalls in Java](https://pvs-studio.com/en/blog/posts/java/1128/)
* How template method can ruin your Java code \(you are here\)
## OOP? The template method?
### OOP\!
Not so long ago, I've written an [article](https://pvs-studio.com/en/blog/posts/java/1103/) on how you can apply OOP in your daily work\. It discusses the theoretical and hands\-on approaches and covers the topic more broadly than we'll do today\. So, if you're interested, I invite you to read that article\. However, don't worry, we'll be revising all the necessary information here\. In this article, let's treat the need to use OOP and adhere to SOLID as a fundamental principle\.
### The template method\!
So, one of the simplest patterns is the template method\. However, if some of you've suddenly forgotten how it's implemented, or if you're still a newbie, let's recall its contents\.
This section covers the basic information about the method, so if you're familiar with it, you may skip right to the next one\. The rest are welcome to the theoretical part\.
Let's pay tribute to GoF and take the classic scheme of this pattern from their [book](https://en.wikipedia.org/wiki/Design_Patterns):
It's that simple\. If you know how to read class diagrams, of course\. Otherwise, we can decipher it using an example in code that strives to appear real\.
Let's say we need to output the contents of the *Person* class to the console \(although, it can be a file or anything else\)\. The class contains only the first and last name\.
<spoiler title="Class contents">
```cpp
public class Person {
private final String name;
private final String surname;
public String getName() {
return name;
}
public String getSurname() {
return surname;
}
public Person(String name, String surname) {
this.name = name;
this.surname = surname;
}
}
```
If you think I don't want to overcomplicate things, then you're right :\)
</spoiler>
We can't just output the class contents, we need to serialize them\. Just for the fun of it, let's imagine we have two serialization formats: json and xml\. Of course, we could do everything in one class and choose the required serialization type via an enumeration, but then we'd violate two SOLID principles:
* SRP: by combining the logic of different serializers into one, we violate the single responsibility principle;
* OCP: by adding new serialization types in the future, we violate the open\-closed principle, since we have to change an existing class\.
Of course, once we remember this, we immediately realize that this isn't the right way\. Instead, let's define an abstract serializer method in our printer class\. The class implementation is trivial:
```cpp
public abstract class AbstractPersonPrinter {
protected abstract String serialize(Person person);
public void print(Person person) {
System.out.println(serialize(person));
}
}
```
All we need to do is create derivatives that implement their own logic\. For json:
```cpp
public class JsonPersonPrinter extends AbstractPersonPrinter {
@Override
public String serialize(Person person) {
var sb = new StringBuilder();
var s = System.getProperty("line.separator");
sb.append("{").append(s);
sb.append(" name: \"").append(person.getName())
.append("\"")
.append(s);
sb.append(" surname: \"").append(person.getSurname())
.append("\"")
.append(s);
sb.append("}");
return sb.toString();
}
}
```
And for xml:
```cpp
public class XmlPersonPrinter extends AbstractPersonPrinter {
@Override
public String serialize(Person person) {
var sb = new StringBuilder();
var s = System.getProperty("line.separator");
sb.append("<root>").append(s);
sb.append(" <name>").append(s);
sb.append(" ").append(person.getName())
.append(s);
sb.append(" </name>").append(s);
sb.append(" <surname>").append(s);
sb.append(" ").append(person.getSurname())
.append(s);
sb.append(" </surname>").append(s);
sb.append("</root>");
return sb.toString();
}
}
```
Voilà\. Now we can configure a logger and get the output in the format we want\. If we ever wanted to get the json or xml output at all\.
<spoiler title="Some logger code">
```cpp
public class ConsoleLogger {
private final AbstractPersonPrinter printer;
public ConsoleLogger(AbstractPersonPrinter printer) {
this.printer = printer;
}
public void logPerson(Person person) {
printer.print(person);
}
....
}
```
</spoiler>
<spoiler title="Some logger output">
json:
```cpp
{
name: "John"
surname: "Doe"
}
```
xml:
```cpp
<root>
<name>
John
</name>
<surname>
Doe
</surname>
</root>
```
</spoiler>
Let's get back to the class diagram\. We can redo it for this example, so that it's easier to understand the previous one:
Okay, the long explanation of the pattern is now over\. Almost\. The last thing to be mentioned: if you thought that it'd be better to use composition \(i\.e\. a strategy\) instead of inheritance, you aren't wrong\. I just wanted to demonstrate a particular pattern, so we shall use it\.
## Case study
### Problem and solution
One could say that the template method is basic in many ways, but there are some non\-obvious parts of it\.
For example, we've had the following task: a web page had a form with mostly editable data\. We needed to keep track of the data before and after the changes\. This way, when a user closed the page, we could notify them that they hadn't saved the changes\. There were many such forms on different pages, so we needed a common solution\.
Let's try to solve it:
1. We create the *ParameterBase* abstract generic class that contains the logic described above\. Copying from DTOs and other objects is performed via reflection, and the logic for storing and updating state is implemented using the memento pattern;
1. Such an approach is pretty rough, so we're not stopping just yet\. We haven't considered such complex things like mapping fields with different data types \(we'll leave them out for simplicity\) and simple things such as ignoring the source object fields for automatic copying\.
We need to fix the second issue somehow\. To do this, we introduce an overridden method where we can specify the fields that we don't need\. Here's a slightly simplified solution that I've written back then:
```cpp
public abstract class ParameterBase<TEntity>
: ObservableValidator where TEntity : class
{
protected virtual List<string> GetIgnoredProperties()
=> new List<string>();
public ParameterBase(TEntity entity)
{
var ignore = GetIgnoredProperties();
var sourceProp = GetType().GetProperties();
var colNumber = sourceProp.Length - ignore.Length;
var colCounter = 0;
foreach (var prop in sourceProp)
if (!(ignore.Contains(prop.Name)))
{
prop.SetValue(this, typeof(TEntity)
.GetProperty(prop.Name, Consts.PropertyBindingFlags)
.GetValue(entity, null), null);
colCounter++;
}
if (colNumber != colCounter)
throw new InvalidOperationException(
"Not every parameter field got its value");
this.PropertyChanged += Change;
}
....
}
```
<spoiler title="The code above is strange in some way">
My Java isn't broken, this is just the C\# code :\) Please take this as a stylistic digression\. I tried to keep the code simple\.
You may ask why C\# is used in the front\-end task, I'll answer that it's the Blazor framework\. Our company actively [uses](https://pvs-studio.com/en/blog/posts/csharp/1023/) it\.
By the way, since we're talking about other programming languages, we have an [article](https://pvs-studio.com/en/blog/posts/cpp/1125/) on a similar topic for C\+\+\.
</spoiler>
The algorithm is quite simple: using reflection, we copy all properties from the generic model to the *ParameterBase* descendant and ignore those specified in the descendant itself\. If the quantity doesn't add up, an exception is thrown\. Actually, the *GetIgnoredMappingProperties* method is a special case of a template method called a **hook**\. The task is complete\. Everything's fine, right?
### Sudden warning
It could be fine\. But after the build is finished, if we enable the incremental analysis, then PVS\-Studio issues the following message for the code above:
[V3068](https://pvs-studio.com/en/docs/warnings/v3068/) Calling overrideable class member 'GetIgnoredProperties' from constructor is dangerous\. ParameterBase\.cs\(34\)
At this point, I have to say that I'm not a big fan of [code smell](https://en.wikipedia.org/wiki/Code_smell) analysis\. Most of the time, one would feel outraged, curse the tool, and [suppress](https://pvs-studio.com/en/docs/manual/0017/) the warning looking like a smarty\-pants\. No need for suspense: in this case, the analyzer is wrong, and my solution has no issue\. That's exactly what I did back then, putting the warning in the project *suppress* file\. This is where I got it from now\.
Sure, you can imagine a possible issue and how to fix it:
1. If we add a constructor to the derivative that accepts additional data and change the behavior of *GetIgnoredProperties* depending on that data, we get exactly the issue mentioned in the diagnostic description;
1. To fix it, we could make the constructor private, put initialization in a separate method, and manage object creation via the factory\.
But why use these fancy tricks just to make the analyzer leave us alone, when it's easier to just suppress the warning? Well, it's boring\.
## Houston, we have a problem
### Danger is near
This case came to my mind when I stumbled upon a similar PVS\-Studio message for Java while browsing DBeaver:
[V6052](https://pvs-studio.com/en/docs/warnings/v6052/) Calling overridden 'isBinaryContents' method in 'TextWithOpen' parent\-class constructor may lead to use of uninitialized data\. Inspect field: binary\. TextWithOpenFile\.java\(77\), TextWithOpen\.java\(59\)
Looking back on my experiences, I wanted to move on but decided to examine the code anyway\. So, the *isBinaryContents* method is in the *TextWithOpenFIle* class:
```cpp
public class TextWithOpenFile extends TextWithOpen {
private final boolean binary;
....
@Override
protected boolean isBinaryContents() {
return binary;
}
....
}
```
It's not exciting\. Let's look at the only code fragment where it's used, though:
```cpp
public TextWithOpen(Composite parent, boolean multiFS, boolean secured) {
super(parent, SWT.NONE);
....
if (!useTextEditor && !isBinaryContents()) {
....
editItem.setEnabled(false);
}
....
}
```
The analyzer pointed to a huge constructor that I've shortened for convenience\. The previously mentioned *isBinaryContents* is used in the condition, whose body I've shortened by about 40 code lines\. Note that we're now in the parent class of *TextWithOpen*\. Now it'd be nice to see what's inside the parent *isBinaryContents*:
```cpp
protected boolean isBinaryContents() {
return false;
}
```
Oh, the **hook** we've discussed above\. So, developers wanted the second condition in the parent class to always be *true* \(don't forget about the negation in it\)\. Okay, what does the diagnostic [documentation](https://pvs-studio.com/en/docs/warnings/v6052/) say?
> The analyzer has detected a parent\-class constructor that uses a method overridden in the derived class\. As a result, the overridden method can be used by uninitialized class fields\.
We need to check the constructor of the *TextWithOpenFIle* class:
```cpp
public TextWithOpenFile(
Composite parent,
String title,
String[] filterExt,
int style,
boolean binary,
boolean multiFS,
boolean secured
) {
super(parent, multiFS, secured); // <=
this.title = title;
this.filterExt = filterExt;
this.style = style;
this.binary = binary; // <=
}
```
Wow\. An error is here\. We call the *TextWithOpenFile* constructor first\. Then, it calls the *TextWithOpen* constructor, where *isBinaryContents* is called\. The *isBinaryContents* method reads the value of *binary* that is *false* by default\. Only **then** the *binary* field is initialized in the *TextWithOpenFile* constructor\.
The most annoying thing is that it's not immediately clear how to fix it\. Simply moving the *super* call down doesn't work, unfortunately :\)
The easiest way would be to put the initialization in a separate method and call it separately in all constructors\. It's nice and simple but inefficient: if we overcomplicate the initialization, the probability of an error when creating a new derivative is higher\.
Using creational patterns would be a good alternative:
* Any factory, as I've mentioned above, would put the object creation process in a separate area\. This will at least remind us about the need for initialization and how it's done;
* The builder pattern also helps in this case\. This is a classic solution for cases where initialization is too complicated\. With the pattern, we can break the initialization into several simpler steps, making it easier to extend it further\.
### Moral of the story
It seems that here I have to admit that my skepticism had been put to shame, and the analyzer warnings shouldn't be ignored\. I'll still stand by my opinion, though\. After all, even our [documentation](https://pvs-studio.com/en/docs/warnings/v3068/) states the following:
> If you do want the program to behave as described above when initializing an object and you want to hide the analyzer warning, mark the message as a false positive\.
In my case, I estimated and still estimate the probability of an error to be incredibly small\. However, there are no guarantees\. Here we have a much more complex initialization with more parameters\. Under these circumstances, a dangerous trick has naturally led to an error\. All in all, sound risk assessment is the key to decision\-making\. It doesn't sound exciting too, I know :\)
## Conclusion
I'd like to end the article here\. I hope you enjoyed reading about how the right approach can lead to a frustrating mistake\. And if using overridden methods in constructors you'll double\-check everything, then my job here is done :\)

## A Reflection on Workflows
It's not uncommon that a team's workflow is "_go clone the repo_" and "_get your pull-requests reviewed_". While not inherently bad, this kind of vaguely defined workflow can be difficult to improve for several reasons:
1. **Team-wide Pain Points:** If running various upgrade commands causes groans, how can we turn these observations into solutions when there's no code to iteratively improve? I've seen teams argue **against** committing frequently because running the required upgrade-commands was too cumbersome. I've seen developers **not want to pull** out of fear it might mess up their setup. These anti-patterns are hard to uproot once established.
2. **Onboarding Complexity:** Without local workflows, onboarding often ends up just a list of manual steps. If new hires encounter a pain point they can probably update the guide, but those changes are likely to just rot themselves. Without code, it's hard to see which steps are redundant or combinable to reduce complexity.
To avoid this, we'll aggressively adopt **local workflows**. Runnable code is easier to iterate on and keep correct through test automation.
> ℹ️ _BTW I've worked on projects that took more than a **week** to get started 😱. This was a shocking waste of time, with senior developers debugging dependencies for hours. We can and must do better._
<br>
### Goals for Our Workflows
To determine our direction, let's consider the [DORA research on software delivery](https://dora.dev). This research identifies what software delivery patterns lead to the best outcomes, and for this article we'll focus on two key metrics that are part of a statistically meaningful pattern that is likely to **cause** improvements to organizational performance:
1. **Minimal time from code committed to that code running in production**, ideally no more than an hour.
2. **Frequent deploys**, ideally each commit resulting in a deployment.
We'll align with these principles to create workflows that enable our team to **continuously pull and push code changes with minimal delay**.
> ℹ️ _BTW for more on the DORA research, check out my articles: [Introduction to "Accelerate", the scientific analysis of software delivery](https://dev.to/jonlauridsen/an-introduction-to-accelerate-its-dora-metrics-30lh) and [The Software Delivery Performance Model](https://dev.to/jonlauridsen/the-software-delivery-performance-model-dora-metrics-2nf4). Their book, [Accelerate: The Science of Lean Software and DevOps](https://www.amazon.com/Accelerate-Software-Performing-Technology-Organizations/dp/1942788339), is highly recommended._
<br>
### Rethinking Branches
This research leads us to a choice: To achieve high-frequency changes, branches are not ideal. Why? Because pushing commits anywhere other than `main` introduces latency. If we're serious about an ideal workflow, we **shouldn't use branches**.
For some, this is a shocking statement. How else can changes land safely? If you rely on branches read on for more details, I promise it's possible to do away with them.
> ℹ️ _BTW for more on trunk-based development, see the [DORA research](https://dora.dev/devops-capabilities/technical/trunk-based-development/) and my [Beginners Intro to Trunk Based Development](https://dev.to/jonlauridsen/beginners-intro-to-trunk-based-development-3158)._
Let's start experimenting!
<br>
## Bootstrapping
The most extreme onboarding will be just a single command with no prior dependencies or requirements. Here’s the simplest way to run a remote script (on Mac and Linux):
```sh
$ curl -Ssf https://…/script | sh
```
Imagine an onboarding guide that's just that one line 😍.
But one small constraint: We'll need to inspect the user's configuration (e.g. to check if [pkgx](https://dev.to/jonlauridsen/perfect-elixir-environment-setup-1145#pgkx) is installed), and to do that we can't pipe to `sh` because that spawns a new shell. Instead, we need to `source` the script. And because we can't pipe to `source` we need to slightly change our ideal invocation:
```sh
$ curl -fsSL https://…/script > /tmp/script && source /tmp/script
```
But that's fine, this is still promising to be an extremely simple onboarding one-liner.
<br>
### Be Careful with System Dependencies
A word of caution before we get to coding: installing system dependencies affects the user's computer as a whole, and it's **not** wise to try to fully automate their installation:
1. It's **invasive**: Some developers have strong preferences, and our script could disrupt their setup. We're asking them to trust a script they don't know, so we should write code that can't cause damage.
2. It's **brittle**: We can't account for everyone's different system setups, so the more sophisticated our solutions are the more we risk our code will fail.
3. It's **unmaintainable**: We invite pointless sophistication where developers with different preferences will add their choice to the automation, and we end up with a mess of sophistication to maintain.
And for what? **pkgx** already has a slick installation process, so no amount of automation is saving much time! Let's instead just **identify missing dependencies** and let the user handle the installation.
<br>
### Maximize Trust
Let's make it clear that our script only suggests actions:
```sh
$ URL="https://raw.githubusercontent.com/gaggle/perfect-elixir/main/bootstrap"
$ curl -fsSL $URL > /tmp/bootstrap && source /tmp/bootstrap
This script bootstraps our development environment by suggesting
what dependencies need to be installed and configured.
To be clear: This script never changes or affects your system,
it only ever inspects and makes suggestions.
Ok to proceed? [y/n]:
```
> {% details 🖥️ Terminal %}
> <!-- 🎬 bootstrap_intro -->
> 
> {% enddetails %}
That should establish trust right from the start.
> ℹ️ _BTW I'm not showing bootstrap code here because it's mostly a simple script that outputs the above text. But if you'd like to follow the details [you're welcome to inspect the full bootstrap script here](https://raw.githubusercontent.com/gaggle/perfect-elixir/main/bootstrap)._
<br>
### The First Step
Let's first check if the developer has **pkgx** installed by verifying the exit code of `which pkgx`. If not installed, instruct the user:
```sh
Ok to proceed? [y/n]: y
• Checking for pkgx… ✓
• pkgx is not installed x
User action required: Install pkgx
──────────────────────────────────
You need to install pkgx. Source this script again afterwards.
pkgx can be installed in various ways, depending on your
preferences:
• Via Homebrew:
$ brew install pkgxdev/made/pkgx
• Via cURL:
$ curl -Ssf https://pkgx.sh | sh
For other ways to install see:
https://docs.pkgx.sh/run-anywhere/terminals
pkgx is the package manager that handles system dependencies,
and it is not currently installed. The installation is simple,
and via Homebrew does not require sudo or other forms of
elevated permissions.
Read more about pkgx on https://pkgx.sh
Source this script again after pkgx has been installed.
```
> {% details 🖥️ Terminal %}
> <!-- 🎬 bootstrap_pkgx -->
> 
> {% enddetails %}
This way the user can proceed at their own pace, but are offered easy copy-pasteable choices.
<br>
### All The Steps
To complete onboarding we'll do three more requirements:
1. Verify pkgx's **shell integration**.
2. Ensure the user has **cloned** our repository.
3. Confirm pkgx provides its **developer environment** (e.g., Elixir, Erlang).
Skipping details for brevity, the final bootstrapping script ends up running like this:
```console
Ok to proceed? [y/n]: y
• Checking for pkgx… ✓
• pkgx is installed ✓
• Checking pkgx shell integration… ✓
• Shell integration is active ✓
• Checking repository is cloned… ✓
• Repository is available ✓
• Checking development environment is active… ✓
• Development environment is active ✓
Good to go
Bootstrapping is done:
✓ pkgx is installed
✓ pkgx shell integration is active
✓ The repository is cloned and ready
✓ All system dependencies are available
This system has been bootstrapped and can now hook into our project 🎉
• Run this command to continue onboarding:
$ bin/doctor
```
> {% details 🖥️ Terminal %}
> Here is the full flow from factory-reset machine to ready to work on the project:
> <!-- 🎬 bootstrap_all_steps -->
> 
> {% enddetails %}
And with that, we’ve unlocked a simple onboarding solution. And the simplicity of the code should invite incremental improvements by the whole team. Nice!
Now let's explore the daily development workflow scripts developers will use regularly.
> ℹ️ _BTW this bootstrapping script may not suit enterprise requirements but can be extended to cover various cases. Keep in mind after its initial "**pkgx is installed**" check the full pkgx ecosystem is available, enabling powerful tools like GitHub CLI and entire programming languages. Bootstrapping can evolve significantly based on needs!_
<br>
## Daily Workflows
To enable developers to quickly pull and push code changes, we need to decide on the scripting language for our workflows. With pkgx, we can use any language, but should we?
<br>
### In Defence of Shell Scripting
Shell scripts are the industry standard for scripting, and are widely used and understood by almost everyone. While they may not be the most elegant choice, they are practical and often low-maintenance. We don't earn any money from writing workflow scripts, so probably our best choice is to avoid unnecessary complexities and go with what is most simple: shell scripting.
<br>
### Doctor
Our first workflow component will be a script to keep our development environment up-to-date, ensuring vital preconditions are met (e.g., the local database is running, migrations are applied, Mix dependencies installed, etc.).
> ℹ️ _BTW I've gotten used to calling this script `doctor` because it verifies the health of our environment. You can choose whatever name you feel is most fitting._
First, let's catch if the user has fallen out of the pkgx ecosystem. By overlapping with where bootstrap left off we provide a fallback for unforeseen errors:
```bash
$ cat bin/doctor
#!/usr/bin/env bash
set -euo pipefail
command which pkgx && which erl && which elixir ||\
(echo "Missing system dependencies, \
run 'source bin/bootstrap'" && exit 1)
```
We can simulate an issue by turning off the development environment:
```console
$ dev off
env -erlang.org=26.2.4 -elixir-lang.org=1.16.2 -postgresql.org=15.2.0
$ bin/doctor
/usr/local/bin/pkgx
Missing system dependencies, run 'source bin/bootstrap'
$ echo $?
1
```
Re-enabling the environment makes the check pass:
```console
$ dev on
env +erlang.org=26.2.4 +elixir-lang.org=1.16.2 +postgresql.org=15.2.0
$ bin/doctor
/usr/local/bin/pkgx
/Users/cloud/.pkgx/erlang.org/v26.2.4/bin/erl
/Users/cloud/.pkgx/elixir-lang.org/v1.16.2/bin/elixir
$ echo $?
0
```
This directs users back to bootstrapping if the pkgx system isn't activated, quite nice.
This implementation is pretty noisy though, and mixes low-level shell implementation with high-level goals. We can improve on that by introducing an abstraction layer via a shell helper function called `check`:
```bash
$ cat bin/doctor
#!/usr/bin/env bash
set -euo pipefail
source "$(dirname "$0")/.shhelpers"
check "Check system dependencies" \
"command which pkgx && which erl && which elixir" \
"source bin/bootstrap"
```
```console
$ bin/doctor
• Check system dependencies ✓
```
> {% details 🖥️ Terminal %}
> <!-- 🎬 doctor_one_check -->
> 
> {% enddetails %}
It's worth taking care of our terminal output to not go blind to all the mindless muck we can otherwise end up printing.
> ℹ️ _BTW the `.shhelpers` code is not directly relevant to this article, but [you can find the full script here](https://github.com/gaggle/perfect-elixir/blob/perfect-elixir-3-development-workflows-%26-processes/bin/.shhelpers) if you'd like. They're inspired by workflows introduced to me by [Eric Saxby](https://github.com/sax) and [Erik Hanson](https://github.com/eahanson) of [Synchronal](https://github.com/synchronal)._
Let's check if our local database is running next:
```sh
$ git-nice-diff -U0 .
/bin/doctor
L#7:
+check "Check PostgreSQL server is running" \
+ "pgrep -f bin/postgres" \
+ "bin/db start"
$ bin/doctor
• Check system dependencies ✓
• Check PostgreSQL server is running x
> Executed: pgrep -f bin/postgres
Suggested remedy: bin/db start
(Copied to clipboard)
$ bin/db start
• Creating /Users/cloud/perfect-elixir/priv/db ✓
• Initializing database ✓
• Database started:
waiting for server to start.... done
server started
↳ Database started ✓
$ bin/doctor
• Check system dependencies ✓
• Check PostgreSQL server is running ✓
```
> {% details 🖥️ Terminal %}
> <!-- 🎬 doctor_two_checks -->
> 
> {% enddetails %}
The **doctor** pattern is now clear: Check for a condition, suggest a fix. Simple to extend, easy to understand.
> ℹ️ _BTW the `bin/db` script abstracts logic away from the doctor script and provides a handy way for developers to manage their database. Its implementation isn't directly relevant but [you can read the full script here](https://github.com/gaggle/perfect-elixir/blob/perfect-elixir-3-development-workflows-%26-processes/bin/db)._
Let's skip to having added all necessary checks for our app to start:
```sh
$ bin/doctor
Running checks…
• Check system dependencies ✓
• Check developer environment ✓
• Check PostgreSQL server is running ✓
• Check PostgreSQL server has required user ✓
• Check mix hex ✓
• Check mix dependencies ✓
• Check PostgreSQL database exists ✓
✓ System is healthy & ready
```
> {% details 🖥️ Terminal %}
> <!-- 🎬 doctor_system_is_healthy -->
> 
> {% enddetails %}
And now we can start our app 🎉:
```sh
$ iex -S mix phx.server
[info] Running MyAppWeb.Endpoint with Bandit 1.4.2 at 127.0.0.1:4000 (http)
[info] Access MyAppWeb.Endpoint at http://localhost:4000
[watch] build finished, watching for changes...
Erlang/OTP 26 [erts-14.2.4] [source] [64-bit] [smp:2:2] [ds:2:2:10] [async-threads:1] [dtrace]
Interactive Elixir (1.16.2) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)>
```
> {% details 🖥️ Terminal %}
> <!-- 🎬 start -->
> 
> {% enddetails %}
We now have `bin/doctor` ensuring our system is ready. And new developers can go from a factory-reset machine to having our product running locally in just a handful of minutes by running **bootstrap** & **doctor**.
<br>
### Update
Next, we'll create a script to easily get the latest code. This will be a **replacement** for `git pull`, as it will pull down the latest changes **and** run necessary commands to apply changes correctly.
> ℹ️ _BTW especially teams that use trunk-based development can generate several dozens of commits per day, so there's good need for a script like this._
First, let's run `git pull`, and then ensure mix dependencies are up-to-date and compiled. The `.shhelpers` library from before has a `step` function that runs a command but hides the output unless an error occurs, which is perfect for this:
```console
$ cat bin/update
#!/usr/bin/env bash
set -euo pipefail
source "$(dirname "$0")/.shhelpers"
check "Check branch is main" \
'[ "$(git rev-parse --abbrev-ref HEAD)" = "main" ]' \
"git checkout main"
step "Pulling latest code" \
"git pull origin main --rebase"
step "Installing dependencies" "mix deps.get"
step "Compiling dependencies" "mix deps.compile"
bin/doctor
$ bin/update
• Check branch is main ✓
• Pulling latest code ✓
• Installing dependencies ✓
• Compiling dependencies ✓
Running checks…
• Check system dependencies ✓
• Check PostgreSQL server is running ✓
• Check PostgreSQL server has required user ✓
• Check mix hex ✓
• Check mix dependencies ✓
• Check PostgreSQL database exists ✓
✓ System is healthy & ready
```
> {% details 🖥️ Terminal %}
> 
> {% enddetails %}
This script makes it easy to integrate the latest changes, and because it ends with running `doctor` we're constantly ensuring our system is in a good state. And we'll add more steps to this script as needed whenever we discover additional tasks that should be run after pulling new code.
> ℹ️ _BTW usually `update` would also apply migrations, but we don't have any yet so I've skipped that for now._
<br>
### Shipit
The final workflow script, `shipit`, is crucial because it will let us safely ship changes. It must ensure our code is in a shippable state by running test automation and other quality gates before pushing the code.
Our needs are simple right now as we don't have much code: we just need to run unit-tests and formatting checks. Here's how we can do that:
```bash
$ cat bin/shipit
#!/usr/bin/env bash
set -euo pipefail
source "$(dirname "$0")/.shhelpers"
bin/update
step --with-output "Run tests" "mix test"
check "Check files are formatted" "mix format --check-formatted" "mix format"
step "Pushing changes to main" "git push origin main"
cecho "\n" -bB --green "✓" --green " Shipped! 🚢💨"
```
And the result is:
```console
$ bin/shipit
Integrating changes…
• Check active branch ✓
• Pulling latest code ✓
• Installing dependencies ✓
• Compiling dependencies ✓
Running checks…
• Check system dependencies ✓
• Check PostgreSQL server is running ✓
• Check PostgreSQL server has required user ✓
• Check mix hex ✓
• Check mix dependencies ✓
• Check PostgreSQL database exists ✓
✓ System is healthy & ready
Checking code…
• Run tests:
.....
Finished in 0.1 seconds (0.05s async, 0.06s sync)
5 tests, 0 failures
Randomized with seed 297141
↳ Run tests ✓
• Check files are formatted ✓
• Pushing changes to main ✓
✓ Shipped! 🚢💨
```
> {% details 🖥️ Terminal %}
> <!-- 🎬 shipit -->
> 
> {% enddetails %}
This provides a safe and quick way to ship code by first updating the code to ensure the environment is in sync, then running tests and checking for any issues, and finally pushing to main. This workflow maximizes Continuous Integration (CI) and Continuous Delivery (CD) by constantly integrating changes and pushing code to production with minimal latency.
All that's left now is to practice shipping frequently, and continuously engage customers for feedback!
> ℹ️ _BTW it's beneficial to adopt these scripts **while they're still raw and simple**. Waiting for them to be "perfect" is IMO a mistake because the clarity and ease of iteration of the initial versions is what builds trust in the workflows. The initial scripts should cover essential needs, and then be allowed to naturally expand. This engages the team and maximizes collective involvement._
<br>
### Check All the Things
We've established workflows that let us continuously integrate changes with `bin/update` and push changes with `bin/shipit` (replacing `git pull` and `git push`). While these scripts can be improved and made more robust by adding more quality gates (e.g., run Dialyzer, prevent compiler warnings, run security scans), there's one aspect we can't automate: **The review**.
Code is improved by multiple pairs of eyes, but how can that be done without adding branches and latency? The answer is simple yet impactful:
**Reviewing must also happen locally**.
Some developers may resist this idea, but it aligns with modern development practices: Discrete reviews, often from code-changes that have been hidden away in branches for hours and days, add latency and friction. We should instead aim for **continuous code reviewing**.
So when a commit is ready, get it reviewed immediately. Don't wait, don't delay, and don't start other work until the current work is reviewed. And to further reduce disruptions just code it together: share a workstation (or use screen sharing remotely) and develop the code collaboratively. This way, changes flow to main without obstacles, enabling true continuous integration and continuous delivery.
Then, practice taking many more much smaller steps, shipping dozens of times an hour.
**Now** we're achieving real continuous integration and continuous delivery 🤩.
> ℹ️ _BTW there is extensive literature on pair and whole-team programming. While negative pairing can be exhausting, positive pairing is very enjoyable 😊. Articles like [Pair Programming by Martin Fowler](https://martinfowler.com/articles/on-pair-programming.html) explain the dos and don'ts, and [Dave Farley's videos](https://www.youtube.com/watch?v=aItVJprLYkg) explore the topic insightfully. Additionally, [Woody Zuill's Mob Programming: A Whole Team Approach](https://www.youtube.com/watch?v=SHOVVnRB4h0) offers insights beyond pairing. For continuous improvement, [Many More Much Smaller Steps by GeePaw Hill](https://www.geepawhill.org/2021/09/29/many-more-much-smaller-steps-first-sketch/) provides excellent inspiration._
<br>
## Test Automating Our Workflows
Testing scripts is often considered too hard, but without tests, iterating on our scripts becomes increasingly difficult. Let's tackle this challenge step-by-step.
<br>
### Testability
To make scripts testable, we need to mock external calls. Running the script in a real environment for every test isn't feasible, so we need a way to simulate these calls.
<br>
### Mocking System Calls
We'll use a `call` command that by default simply wraps external calls, but it also allows itself to be mocked during tests. Here's a basic implementation we can wire into the start of our scripts, which defines `call` only if it doesn't already exist:
```bash
# Define call if 'call' is not already a command
if ! type call >/dev/null 2>&1; then
call() { "$@"; }
fi
```
Under test conditions, we can replace `call` with a mock implementation:
```console
$ call() { echo "called with: $*" > call.log; return 1; }
$ source bin/bootstrap
…
Ok to proceed? [y/n]: y
• Checking for pkgx… ✓
• pkgx is not installed x
…
$ cat call.log
called with: which pkgx
```
What we see above is that our mocked `call` gets invoked when we run bootstrap, allowing us to control its behavior and verify that our script responds correctly.
To put it into our bootstrapping context, we can wrap it all into an easier-to-use script that lets us configure and create a mocked `call` command, like this:
```console
$ export MOCK=$(test/mcall configure "which pkgx|1|")
$ source test/mcall
$ source bin/bootstrap
…
Ok to proceed? [y/n]: y
• Checking for pkgx… ✓
• pkgx is not installed x
…
$ test/mcall assert
All mocks used ✓
```
And that's it. That's one fully tested use case right there!
Well, sort of: I did have to manually answer `y` to bootstrap's prompt. How do we automate that?
> ℹ️ _BTW it's possible this complexity in testing shell scripts should be a reason to switch away from shell scripting. Maybe if we were writing all this in a more comprehensive programming language, we could use their mature test-runners to more easily achieve test-automation? It's worth considering, although for now I'll stay the course to see if this is even possible to solve._
<br>
### Expect
Next, we need to interact with our scripts and assert their outputs. For this, we'll use `expect`, a tool for automated interaction with programs:
```console
$ expect -c 'spawn echo "foo"; expect "foo"; expect eof'
spawn echo foo
foo
```
To test our bootstrap script, we can create an `expect` script:
```console
$ cat test/expect.exp
#!/usr/bin/env expect
set timeout 3
expect_before {
timeout { puts "timeout"; exit 2 }
}
spawn bash
send "source bin/bootstrap\r"
expect "Ok to proceed? [y/n]:"
send "n\r"
send "exit\r"
expect eof
```
Running this script simulates user interaction and validates the output:
```console
$ ./test/expect.exp
…
Ok to proceed? [y/n]: n
exit
bash-5.2$ exit
exit
$ echo $?
0
```
Cool.
And note: `expect` is **quite** extensible because it's based on the `Tcl` language (pronounced "tickle"). It has a great history dating back to the late 80s, and is a proper language with procedures and conditionals and much more.
> ℹ️ _BTW the full `expect` script I ended up with takes additional arguments and pretty-prints some details. [It's available here](https://github.com/gaggle/perfect-elixir/blob/perfect-elixir-3-development-workflows-%26-processes/test/run-expect-scenario) if you're curious._

To manage our tests, ensuring they all get run and tracking which ones pass and which fail, we'll turn to the **[Bash Automated Testing System](https://bats-core.readthedocs.io)** (bats). It lets us define tests in a bootstrap.bats file like this:
```bash
@test "pkgx not installed" {
run_mocked_scenario '
which pkgx|1|pkgx not found
' \ '
send "source bin/bootstrap\n"
exp "Ok to proceed?"
send "y\n"
exp "pkgx is not installed"
exp "User action required: Install pkgx"
exp_prompt
'
}
$ bats test/bootstrap.bats
bootstrap.bats
✓ pkgx not installed
1 test, 0 failures
```
> ℹ️ _BTW here I'm skipping over some details to not extend this article even more. The above snippet actually calls a bats helper function that orchestrates `mcall` and `expect`. The [full bootstrap.bats is available here](https://github.com/gaggle/perfect-elixir/blob/perfect-elixir-3-development-workflows-%26-processes/test/bootstrap.bats) if you'd like to follow all the details._
Finally, we can write tests for all possible use cases to ensure our script behaves as expected:
```console
$ bats test/bootstrap.bats
bootstrap.bats
✓ no to proceed
✓ pkgx not installed
✓ pkgx is too old
✓ pkgx is missing dev integration
✓ pkgx is missing env integration
✓ folder is not a repository
✓ remote is not expected repository
✓ no erl so should activate dev
✓ no elixir so should activate dev
✓ no psql so should activate dev
✓ good to go with git remote
✓ good to go with https remote
12 tests, 0 failures
```
> {% details 🖥️ Terminal %}
> <!-- 🎬 bats-bootstrap -->
> 
> {% enddetails %}
These tests help guard against regressions and ensure our scripts work across different shells. They've been very helpful in driving out several small bugs that would have otherwise plagued these scripts.
If you have simpler methods for testing interactive scripts, please share them!

Instead of copying and pasting the same code with minor changes, dynamic blocks let you write the configuration once and dynamically generate the variations based on input values.
This blog will dive into [Terraform](https://www.env0.com/blog/what-is-terraform-cli) dynamic blocks and their components like `label`, [`for_each`](https://www.env0.com/blog/terraform-for-each-examples-tips-and-best-practices), `iterator`, and `content`.
We will also explore various use cases and practical scenarios, such as:
1. creating EC2 instances with specific Amazon EBS volume configurations
2. applying dynamic blocks in resource and data blocks
3. implementing multilevel nested dynamic blocks
> **_Disclaimer_**_All use cases for dynamic blocks in Terraform discussed here work similarly in_ [_OpenTofu_](https://www.env0.com/blog/opentofu-the-open-source-terraform-alternative)_, the open-source Terraform alternative. However, to keep it simple and familiar for DevOps engineers, we will refer to them as Terraform dynamic blocks throughout this discussion._
**Where to Use Dynamic Blocks**
-------------------------------
Here are some situations where dynamic blocks prove to be helpful:
* **Creating Multiple AWS Subnets**: Suppose you need to create subnets in different availability zones. Rather than writing separate blocks for each subnet, you can use a dynamic block to iterate over a list of availability zones and create a subnet for each one.
* **Configuring Security Group Rules**: When managing many security group rules, dynamic blocks help you define and organize them compactly. Instead of writing each rule separately, you can use a dynamic block to iterate over a list of rules, which simplifies the configuration
* **Provisioning Multiple EC2 Instances**: If you need multiple EC2 instances with similar configurations but different attributes (like tags or instance types), dynamic blocks allow you to handle this efficiently.
**Components of Terraform Dynamic Blocks**
------------------------------------------
Dynamic blocks contain four main components - the `label`, `for_each`, `iterator`, and `content`.
Here's a detailed explanation of each:
### **Basic Syntax**
To demonstrate how these work, let's use an example of a dynamic block that creates multiple configurations based on a list of input values.
Here’s what that dynamic block's syntax would look like:
dynamic "label" {
for_each = var.iterable_variable
iterator = iterator_name # Optional, defaults to label
content {
# Configuration details for each iteration
attribute = iterator_name.value
}
}
In this configuration:
* The `label` specifies the type of dynamic block to create.
* The `for_each` statement loops through a list or map provided by `var.iterable_variable`, creating a block for each item.
* The `iterator` is an optional name for the current item in the loop. If not specified, Terraform uses the label name by default. This iterator allows you to reference the current item being processed.
* The `content` block contains the configuration details for each generated block, using `iterator_name.value` to insert the appropriate value for each iteration.
Let's apply this dynamic block syntax in a real-world scenario where we provision multiple EC2 instances and attach specific EBS volumes based on their instance IDs.
First, let's create a **main.tf** file. To use this, we need to retrieve existing instances using a data block and create a local variable to hold the instance IDs:
In this configuration, the data `aws_instances`, `existing_instances` block fetches existing running EC2 instances. The `locals` block creates a local variable `instance_ids` that stores the IDs of the fetched instances.
Next, we will use a dynamic block to apply specific EBS configurations to EC2 instances based on their instance IDs.
We will dynamically attach different EBS volumes to the specified instances by iterating over the instance IDs. This approach ensures that each instance receives the appropriate EBS volume settings without redundant code.
Here is how our resource block will look:
resource "aws_instance" "dynamic_instance" {
for_each = {
for instance_id in local.instance_ids :
instance_id => instance_id
}
ami = "ami-0c55b159cbfafe1f0"
instance_type = "t2.micro"
tags = {
Name = each.key
}
dynamic "ebs_block_device" {
for_each = [
for id in local.instance_ids : id
if id == "i-0d5933a76d45a6aee"
]
content {
device_name = "/dev/sdh"
volume_size = 10
encrypted = true
}
}
dynamic "ebs_block_device" {
for_each = [
for id in local.instance_ids : id
if id == "i-095aff1e2acc82958"
]
content {
device_name = "/dev/sdh"
volume_size = 20
encrypted = true
}
}
}
In this resource block, the `for_each` statement iterates over the `instance_ids` to create a resource for each instance.
The dynamic blocks `ebs_block_device` iterate over the instance IDs and attach specific EBS volumes to instances with `IDs i-0d5933a76d45a6aee` and `i-095aff1e2acc82958`, ensuring each instance receives the correct EBS volume settings.
**How to Use Terraform Dynamic Blocks**
---------------------------------------
Dynamic blocks are supported inside resource, data, provider, and provisioner blocks. This section will focus on applying dynamic blocks within resource and data blocks.
### **Applying Dynamic Blocks in Resource Blocks**
Dynamic blocks can be applied within resource blocks to handle configurations that repeat with slight variations. This is useful for resources that require nested blocks for repeated configurations, such as AWS security groups with multiple ingress and egress rules.
For example, you can [apply](https://www.env0.com/blog/terraform-apply-guide-command-options-and-examples) dynamic blocks within a resource block to create AWS security groups.
We'll define variables for subnets and security group rules in our **variables.tf**. These variables will hold the configurations needed for creating subnets and security group rules in AWS.
variable "subnets" {
description = "A list of maps, where each map contains subnet-specific attributes"
type = list(object({
cidr_block = string
az = string
}))
default = [
{
cidr_block = "10.0.1.0/24"
az = "us-west-2a"
},
{
cidr_block = "10.0.2.0/24"
az = "us-west-2b"
},
{
cidr_block = "10.0.3.0/24"
az = "us-west-2c"
}
]
}
variable "security_group_rules" {
description = "A list of security group rules"
type = list(object({
type = string
from_port = number
to_port = number
protocol = string
cidr_blocks = list(string)
}))
default = [
{
type = "ingress"
from_port = 80
to_port = 80
protocol = "tcp"
cidr_blocks = ["0.0.0.0/0"]
},
{
type = "ingress"
from_port = 443
to_port = 443
protocol = "tcp"
cidr_blocks = ["0.0.0.0/0"]
}
]
}
Now, let's create an `aws_security_group` resource with a dynamic block configuration:
resource "aws_security_group" "env0_security_group" {
name = "env0-security-group"
vpc_id = aws_vpc.env0_vpc.id
dynamic "ingress" {
for_each = [for rule in var.security_group_rules : rule if rule.type == "ingress"]
content {
from_port = ingress.value.from_port
to_port = ingress.value.to_port
protocol = ingress.value.protocol
cidr_blocks = ingress.value.cidr_blocks
}
}
dynamic "egress" {
for_each = [for rule in var.security_group_rules : rule if rule.type == "egress"]
content {
from_port = egress.value.from_port
to_port = egress.value.to_port
protocol = egress.value.protocol
cidr_blocks = egress.value.cidr_blocks
}
}
tags = {
Name = "env0-security-group"
}
}
In the Terraform code above, dynamic blocks are used to iterate over the `security_group_rules`.
For each ingress rule, a new ingress block is created with the specified ports, protocol, and CIDR blocks.
Similarly, for each egress rule, a new egress block is created. This ensures that all specified rules are dynamically applied to the security group, streamlining the configuration and maintaining consistency across the setup.
### **Applying Dynamic Blocks in Data Blocks**
Dynamic blocks can also be used within data blocks to retrieve information on the go. This approach is useful when you query resources based on varying criteria and dynamically generate the query filters.
For example, you need to find all EC2 instances in your AWS account that match specific criteria, such as being in a "running" state and having a specific tag. Instead of manually specifying each filter, you can use dynamic blocks to define these filters programmatically.
resource "aws_instance" "env0_instance" {
ami = "ami-09040d770ffe2224f"
instance_type = "t2.micro"
tags = {
Name = "env0-instance"
Environment = "env0"
}
}
variable "instance_filters" {
description = "A list of filters for finding EC2 instances"
default = [
{
name = "instance-state-name"
values = ["running"]
},
{
name = "tag:Environment"
values = ["env0"]
}
]
}
data "aws_instances" "env0_instances" {
dynamic "filter" {
for_each = var.instance_filters
content {
name = filter.value.name
values = filter.value.values
}
}
}
output "instance_ids" {
value = data.aws_instances.env0_instances.ids
}
In this configuration, the dynamic block within the data block iterates over the `instance_filters` variable.
For each filter in the list, it creates a filter block with the specified name and values, allowing you to query EC2 instances based on dynamic criteria. The resulting instance IDs are then output for further use.
By using dynamic blocks in both resource and data blocks, you can create more flexible and maintainable Terraform configurations that adapt to varying requirements and reduce redundancy in your code.
**Multilevel Nested Dynamic Blocks**
------------------------------------
Nested dynamic blocks allow you to handle more complex configurations by embedding one dynamic block inside another.
This is particularly useful when dealing with resources that have nested configurations requiring iteration over multiple levels of nested blocks – for example, when defining custom attributes with constraints for AWS Cognito User Pools.
### **How to Implement Nested Dynamic Blocks**
Implementing nested dynamic blocks involves using one dynamic block inside another, allowing each level to iterate over its own set of values.
For example, to create an AWS Cognito User Pool with nested custom attributes, we can define variables for the custom attributes and their constraints. Nested dynamic blocks are then used to generate the schema, iterating over the attributes and their constraints to build the complete configuration efficiently.
First, let us define `env0_user_pool_custom_attributes` variable for user pool custom attributes and their constraints in our **variables.tf** file, which will hold a list of custom attribute configurations for an AWS Cognito User Pool:
variable "env0_user_pool_custom_attributes" {
description = "List of custom attributes for the user pool"
type = list(object({
name = string
attribute_data_type = string
is_required = bool
is_mutable = bool
string_attribute_constraints = list(object({
min_length = number
max_length = number
}))
}))
default = [
{
name = "custom-attribute"
attribute_data_type = "String"
is_required = false
is_mutable = true
string_attribute_constraints = [
{
min_length = 4
max_length = 256
}
]
}
]
}
Next, we will create the `aws_cognito_user_pool` resource using nested dynamic blocks to define the schema for the user pool:
resource "aws_cognito_user_pool" "env0_production_user_pool" {
name = "env0-production-user-pool"
dynamic "schema" {
for_each = var.env0_user_pool_custom_attributes
content {
name = schema.value.name
attribute_data_type = schema.value.attribute_data_type
mutable = schema.value.is_mutable
required = schema.value.is_required
dynamic "string_attribute_constraints" {
for_each = lookup(schema.value, "string_attribute_constraints", [])
content {
min_length = string_attribute_constraints.value.min_length
max_length = string_attribute_constraints.value.max_length
}
}
}
}
}
Here, the outer dynamic block schema iterates over the `env0_user_pool_custom_attributes` variable to create a schema for each custom attribute. Inside the schema block, another dynamic block `string_attribute_constraints` iterates over the constraints for each attribute.
This setup dynamically creates a schema entry for each custom attribute and applies the specified constraints, such as minimum and maximum lengths, ensuring a flexible and efficient configuration.
You can manage complex Terraform configurations more effectively using nested dynamic blocks to reduce redundancy and improve maintainability. This technique is beneficial for handling resources that require deep nesting and multiple levels of dynamic configurations.
**Terraform Dynamic Blocks with env0**
--------------------------------------
[env0](https://www.env0.com/) is a powerful platform designed to streamline IaC workflows, making managing and deploying cloud infrastructure easier. By integrating with tools like Terraform or OpenTofu, env0 enhances control over cloud deployments. Let’s look at an example that demonstrates how to use env0 to automate the creation of multiple AWS subnets using Terraform dynamic blocks.
**Setting Up env0**
1. On your env0 dashboard, create a new project. Name it something like "AWS VPC Project".
2. Connect your Git repository where your Terraform code is stored. If you don't have a repository, create one and push your Terraform configuration to it.
3. Set the required variables, such as AWS credentials and any Terraform variables you’ve defined.
4. Click the deploy button to start Terraform deployment. env0 will handle the execution and provide logs and outputs.
By using [env0](https://www.env0.com/) and dynamic blocks together, you can efficiently manage and automate the creation of multiple AWS subnets.
This approach makes your Terraform code more scalable and maintainable. With env0, you benefit from streamlined deployments and centralized infrastructure management.
**Conclusion**
---------------
In this blog, we explored how to use Terraform dynamic blocks to create AWS subnets, configure security group rules, and set up EC2 instances efficiently. We also looked at nested dynamic blocks for handling complex setups, like custom attributes for AWS Cognito User Pools.
By using [env0](https://www.env0.com/) to automate Terraform deployments, we made the process easier and more organized. This combination helps keep your infrastructure scalable, maintainable, and free from repetitive tasks, letting you focus on more important work.
**Frequently Asked Questions**
-------------------------------
#### **Q: What is a dynamic block vs. static block in Terraform?**
Terraform dynamic block allows you to generate multiple nested blocks within a resource or module based on a `for_each` expression.
This is useful when the number of blocks is not fixed or doesn’t need to be computed. A static block is a fixed configuration written directly into the Terraform code, specifying the exact settings without iteration or computation.
#### **Q: What is one disadvantage of using dynamic blocks in Terraform?**
One disadvantage of using dynamic blocks in Terraform is that they can make the configuration harder to read and understand.
This can be particularly challenging for new team members or when the logic within the dynamic block becomes complex, potentially leading to maintenance difficulties.
#### **Q: What is the difference between dynamic block and for_each in Terraform?**
The difference between a dynamic block and `for_each` in Terraform lies in their use cases.
A dynamic block dynamically creates multiple nested blocks within a single resource or module, allowing for flexible configuration of nested elements. On the other hand, `for_each` iterates over a set of values to create multiple instances of a resource or module, enabling the creation of several independent resources based on a collection.
#### **Q: What is a dynamic tag in Terraform?**
A dynamic tag in Terraform is a tag created using a dynamic block, which allows tags to be generated based on a `for_each` expression or other dynamic conditions.
This approach enables more flexible and programmatic tagging of resources, adapting to different scenarios and requirements without hardcoding each tag. | env0team |

In this article, we will learn how to create a local Kubernetes cluster using [kind](https://kind.sigs.k8s.io/).
[Kind](https://kind.sigs.k8s.io/) (Kubernetes in Docker) is a tool for running local Kubernetes clusters using Docker container “nodes”. kind was primarily designed for testing Kubernetes but may be used for local development or CI.
## Installation
Depending on your OS you can check the documentation [here](https://kind.sigs.k8s.io/). If you are on Windows like me you can:
- Install with A Package Manager [chocolatey](https://chocolatey.org/install). Once chocolatey is installed run the command below:
```
choco install kind
```
- Install from release binaries with PowerShell
```
curl.exe -Lo kind-windows-amd64.exe https://kind.sigs.k8s.io/dl/v0.23.0/kind-windows-amd64
Move-Item .\kind-windows-amd64.exe c:\some-dir-in-your-PATH\kind.exe
```
Since Kind leverages docker, you will need to have docker installed on your machine or you can let Kind install it for you during the process. You can run the command below to check if it has been successfully installed.
```
kind --version
```
## Creating a cluster
Once you have Kind installed we create a cluster by running the command below:
```
kind create cluster
```
It will create and run a docker container on your machine, that container will act as the control plane of your cluster and all the control plane components will be installed in it. Run the command below to check the containers that are currently running:
```
docker ps
```
We have one container running with the name kind-control-plane, this is our first cluster. It’s a cluster with a single node that will act as a node and control plane as well.
### Cluster with a name
The cluster created above has the name `kind` which is the name by default but we can create a new cluster and specify a different name:
```
kind create cluster --name second-cluster
```
Now we have two clusters, the first is kind the second second-cluster.
### Cluster with multiple nodes
In production most of the time we have multiple nodes for running our apps, it’s always better to have the same infra locally for testing. Kind allows us to create a cluster with multiple nodes (control plane and worker nodes), to do that we have to create a file to specify the configuration.
```
# three node (two workers) cluster config
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
- role: worker
- role: worker
```
Create a file named `kind-example-config.yaml` copy and paste the content above then run the command below:
```
kind create cluster --config kind-example-config.yaml
```
The cluster has been successfully created and you can see from the image below we have three containers running, the control plane, and two workers nodes.
You can expose extra ports for the worker nodes so they can be accessible from the machine, to do that you have to update your configuration:
```
apiVersion: kind.x-k8s.io/v1alpha4
kind: Cluster
nodes:
- role: control-plane
extraPortMappings:
- containerPort: 30000
hostPort: 30000
listenAddress: "0.0.0.0" # Optional, defaults to "0.0.0.0"
protocol: tcp # Optional, defaults to tcp
- containerPort: 31321
hostPort: 31321
- containerPort: 31300
hostPort: 31300
- role: worker
- role: worker
```
## Deleting a cluster
You can delete a cluster by running the command below:
```
kind delete cluster
```
If the cluster’s name is mentioned, it will delete the default cluster the one that has the name `kind`
```
kind delete cluster --name second-cluster
```
### Interact with the cluster
Once kind is installed we can already use the `kubectl` commands:
```
kubectl get node
```
If you have multiple clusters on your machine you have to specify the name of the cluster as context for each command:
```
Kubectl get nodes --context kind-kind-2
# or
kubectl get nodes --context kind-second-cluster
```
## Load docker images
One of the advantages of having a local cluster is that we don’t need to host our images in a registry to use them in Kubernetes Deployment. But since our nodes are running inside containers we have to make our images available inside those containers so they can be used. To do that Kind provide a command to load images into the cluster nodes:
```
kind load docker-image my-image-name:tag
```
This will make the image `my-image-name` available for use in the cluster.
## Install Helm
From now we have a working Kubernetes cluster, we might need Helm to easily install packages. According to your OS check the [documentation](https://helm.sh/docs/intro/install/). If you are on Windows like me you can install it by using chocolatey.
```
choco install kubernetes-helm
```
```
helm version
```
### Install nginx using Helm
- Add and update the repo:
```
helm repo add stable https://charts.helm.sh/stable
helm repo update
```
- Install Nginx
```
helm install my-nginx stable/nginx-ingress
```
- Get the pods list
- Get the services list
We have nginx running inside our cluster.
## Conclusion
Throughout the article, we have discovered what is Kind and how to create a Kubernetes cluster for local development. In the next article, we will learn how to deploy our first app in Kubernetes.
I hope you enjoy this article as much as I enjoyed writing it.

That might not be a problem if you order a static IP from your ISP, but not all ISPs make it easy or cheap. There are also several reasons you might want to avoid that.
## Current setup
In my initial post I suggested using Intel NUC to host every tool in the closed off local network that only you have access too. Basically you can install server version of Ubuntu, setup ssh access, install docker, and run any tool you need on that docker (I will post extensive guide in the future). I'm using also Portainer and Traefik as my main containers to actually bind any local address to a new service, so I don't have to jump on different ports, depending on what I want. Now your local address becomes something like portainer.home.local.
## Moving to public
Now, this type of routing can be incorporated in public environment if you had domain pointing to your static IP, port-forwarded 80 and 443 to your intel NUC from router, and let Traefik take over routing over subdomains. That's classic way of routing traffic. In fact, that's not so different from spinning up EC2 with docker and doing that yourself on external network. Definitely it's safer this way.
But we are going the economic way, and actually the best of both worlds: tunneling. That's right, we will make a bridge between the domain and our container. This way traffic comes from indirect source instead of directly through our router and local network. You can even set up docker network so it's closed off from the rest of your internal network.
There are several tools that allows tunneling like [ngrok](https://ngrok.com/) or [tunnelmole](https://tunnelmole.com/), however, best option is actually [Cloudflare](https://cloudflare.com/). It's free for small amounts of traffic, and works best in docker environment.
### Step 1. Get the domain
Honestly, you can't go public without domain, if you don't have one, you have to grab one. Keep in mind that you need to point DNS towards Cloudflare nameservers so you can't use one that already is occupied by something else. Best services that provide domains for me are:
- [GoDaddy](https://www.godaddy.com/en-uk) - I've been using them for years. I had good experience with their customer service, and most of my domains sits there.
- [NameCheap](https://www.namecheap.com/) - Name says it all. Solid alternative, some domains comes cheaper then GoDaddy, some don't. But one of the main benefit is - they have `.xyz` domains for $1 a year!
### Step 2. Set up a domain on cloudflare.
Now let's create account on cloudflare and add our domain. Go to websites and add new domain.
After you provide domain you already own, you will be asked to subscribe... don't worry, there is free tier, scroll down:
Do the quick domain scan, click on next, until you get to activation page:
Scroll down until you see nameservers:
Set up DNS records to point to your cloudflare nameservers (don't copy from me, these can be different for you)
Now, you need to wait until domain propagates correctly. Depending on where you have your own DNS servers set up, it can take between 5 minutes up to 24 hours.
### Step 3: Tunnel your traffic.
Alright, we have cloudflare account and domain set and ready. Let's setup our proxy bridge. Go to "Zero Trust" section:
Now expand "Networks" section and select "Tunnels":
Now click on "Create a tunnel" and on the next screen select "Cloudflared". Name your tunnel on the next screen.
Your tunnel is created, now you have to install it in your docker. But before we do that, we need to setup our network.
```bash
$ docker network create -d bridge public_services
$ docker run --network=public_services cloudflare/cloudflared:latest tunnel --no-autoupdate run --token <your-token>
$ docker run --name hello-world --network=public_services -d -p 80:80 strm/helloworld-http
$ docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' hello-world
$ # 172.17.0.3
```
This way your tunnel will have access only to services that run on the same network. Last command is what you need to get internal networks container ip. We will need that for tunneling.
Let's get back to cloudflare and let's make new routes. Edit your tunnel and go to "Private Network"
Here set up which networks should be visible in your tunnel. Set up CIDR accordingly to your container's IP.
Now go to "Public Hostname" tab, and click "Add a public hostname"
Here we set up our routing to a specific domain. We can run multiple services this way, each with it's own specific subdomain, or we can set up our personal website. The best thing is - there are no limitations to technology you want to use, as long as it's dockerized.
## Conclusion
Setting up a personal domain and hosting your own services can be a daunting task, especially if you're concerned about security and exposing your local network to the public internet. With docker and Cloudflare however it can be actually quite rewarding and fairly safe. It is good extension of your homelab if you have one, without a need to resort to traditional hosting.
With this setup, you can host a variety of services, from personal websites to custom applications, all while maintaining a secure and isolated environment. The possibilities are endless, and the best part is that you have complete control over your data and services.
So, if you've been hesitant to explore the world of self-hosting due to security concerns or technical challenges, give this method a try. You might be surprised at how easy and rewarding it can be to have your own little corner of the internet, all while keeping your local network safe and sound.

By treating individual objects and composite objects uniformly, this pattern enhances the flexibility and maintainability of your software. Let's explore this pattern through a clear, step-by-step approach using a real-world analogy.
#### Real-World Analogy: File System
Consider a file system on your computer. Files and folders are organized hierarchically. Folders can contain files or other folders, which can further contain files or folders, and so on. This hierarchy is a perfect example where the Composite Design Pattern is beneficial.
### Step-by-Step Guide to the Composite Design Pattern
#### Step 1: Designing the Component Interface
First, define an interface that represents both individual and composite objects. In our file system analogy, this interface might be called `FileComponent`.
```java
public interface FileComponent {
void showDetails();
}
```
#### Step 2: Implementing the Interface with Leaf and Composite Classes
Next, implement this interface with both leaf and composite classes. Leaf classes represent individual objects (files), and composite classes represent composite objects (folders).
**Leaf Class: File**
```java
public class File implements FileComponent {
private String name;
private long size;
public File(String name, long size) {
this.name = name;
this.size = size;
}
@Override
public void showDetails() {
System.out.println("File: " + name + " [Size: " + size + " bytes]");
}
}
```
**Composite Class: Folder**
```java
import java.util.ArrayList;
import java.util.List;
public class Folder implements FileComponent {
private String name;
private List<FileComponent> components = new ArrayList<>();
public Folder(String name) {
this.name = name;
}
public void addComponent(FileComponent component) {
components.add(component);
}
public void removeComponent(FileComponent component) {
components.remove(component);
}
@Override
public void showDetails() {
System.out.println("Folder: " + name);
for (FileComponent component : components) {
component.showDetails();
}
}
}
```
#### Step 3: Sending Requests from Client to Composite Using Component Interface
Clients interact with the composite structure through the component interface. They can treat both leaf and composite objects uniformly.
**Client Class**
```java
public class CompositePatternDemo {
public static void main(String[] args) {
FileComponent file1 = new File("Document1.txt", 1200);
FileComponent file2 = new File("Document2.txt", 1500);
Folder folder = new Folder("MyDocuments");
folder.addComponent(file1);
folder.addComponent(file2);
FileComponent file3 = new File("Image.png", 2500);
Folder subFolder = new Folder("Images");
subFolder.addComponent(file3);
folder.addComponent(subFolder);
folder.showDetails();
}
}
```
### When to Use the Composite Design Pattern
1. **Hierarchical Relationships**: Ideal for scenarios with hierarchical structures like file systems, organizational charts, or graphical compositions where objects can be both individual elements and parts of a larger structure.
2. **Uniform Operations**: When you need to perform similar operations on individual elements and composite structures. The Composite Pattern ensures consistent behavior across different types of elements.
3. **Recursive Processing**: Useful when traversing through a hierarchy of elements to perform operations on each element or group. The Composite Pattern simplifies this by providing a unified approach.
### Conclusion
The Composite Design Pattern simplifies the management of complex hierarchical structures by treating individual objects and composites uniformly. By following these steps and leveraging real-world analogies, you can enhance the flexibility, readability, and maintainability of your software systems.

Typescript requires that we specify the types for the different variables and function arguments in React. When they are native types it is not intrincate, but for React components it can be different. Here are 3 ways to specify types for React components that contain children as part of their props.
## Types With ReactNode
The easiest way is manually, by specifying children as an optional React node.
``` javascript
import React from 'react'
type Props = {
children?: React.ReactNode
}
const MyComponent = ({ children }: Props) => {
return (
<div>
{children}
</div>
)
}
export default MyComponent
```
## Using React.FC
The second way is to use a FC (Functional Component) object provided by React, which leaves implicit the use of children and also prevents us from returning undefined. Consider that using _React.FC_ is [considered by some developers as a bad practice](https://coffeebytes.dev/en/why-using-react.fc-could-be-a-bad-practice/).
``` javascript
import React from 'react'
const MyComponent: React.FC<{}> = ({ children }) => {
return (
<div>
{children}
</div>
)
}
export default MyComponent
```
## React.PropsWithChildren
The last way is to make use of the PropsWithChildren object provided by React which, as its name says, already includes the props with the children component, ready to be used directly.
``` javascript
import React from 'react'
type Props = React.PropsWithChildren<{}>
const MyComponent = ({ children }: Props) => {
return (
<div>
{children}
</div>
)
}
export default MyComponent
```

1,889,888 | The backdrop-filter CSS property has been unprefixed | The backdrop-filter CSS property required a prefix 1 in Safari since forever, well 2015 to be more... | 0 | 2024-06-17T12:00:00 | https://www.roboleary.net/blog/unprefixing-backdrop-filter/ | css, webdev | The [`backdrop-filter`](https://developer.mozilla.org/en-US/docs/Web/CSS/backdrop-filter) CSS property required a prefix [^1] in Safari since forever, well 2015 to be more precise. You *had to* use `-webkit-backdrop-filter` just for Safari's sake. Starting in Safari 18 beta, you don’t need the prefix! 🤗
Mostly you don't need to pay attention to prefixes, they affect only a small portion of CSS properties nowadays. *But* occasionaly, they can trip you up! That is the case with the `backdrop-filter` property. Its adoption has been staggered. Support was added to Chrome in 2019 and Firefox in 2022, and they did not require a prefix. This is why prefixes can be easily overlooked!
Safari has also stated that it has improved the implementation of the property, and boosted its cross-browser interoperability. You should be able to use this property with no caveats going forward soon.
## Where is `backdrop-filter` used?
If you are not familiar with `backdrop-filter`, it is having a moment with the [glassmorphism](https://www.nngroup.com/articles/glassmorphism/) trend. This is maybe why it has caught the attention of Apple again!
There are even dedicated generators such as the aptly named [Glassmorphism CSS Generator](https://ui.glass/generator/) that spit out a CSS snippet with the property. If you have used that generator, you are lucky because it includes the prefixed version of the property for you, so you avoided a Safari mishap!
A beautiful example of its usage is [Aysenur Turk's redesign of the Adobe Creative Cloud app](https://codepen.io/TurkAysenur/pen/ZEpxeYm).
{% codepen https://codepen.io/TurkAysenur/pen/ZEpxeYm %}
There are other use cases for `backdrop-filter`, but that is a topic for another day!
## Final words
Trimming the technical debt of the "web platform" is progress. I think that unprefixing properties often goes unnoticed and is underappreciated. I appreciate it! Kudos to Safari for doing this work!
You should be able to use `backdrop-filter` with no caveats going forward soon! 🙏
[^1]: Browser vendors used to add prefixes to experimental or nonstandard CSS properties to enable developers to experiment with new ideas. It led to a raft of issues. Thankfully, browser vendors moved from "prefixing", favouring feature flags inside the browser settings instead. However, there are still properties that were never unprefixed!

1,891,150 | Understanding the Basics: What is Electronic Data Interchange (EDI)? | In today’s digital age, businesses are constantly looking for efficient and cost-effective ways to... | 0 | 2024-06-17T11:55:09 | https://dev.to/actionedi/understanding-the-basics-what-is-electronic-data-interchange-edi-1h3n | In today’s digital age, businesses are constantly looking for efficient and cost-effective ways to streamline their operations. Electronic Data Interchange (EDI) is a solution that has transformed the way companies exchange information. But what exactly is EDI?
EDI is the electronic interchange of business documents between trading partners in a standardized format. It enables businesses to send and receive data electronically, eliminating the need for paper-based transactions. By utilizing agreed-upon message standards, such as EDIFACT or ANSI X12, EDI facilitates the exchange of purchase orders, invoices, shipping notices, and other business documents seamlessly and securely.
Implementing EDI offers numerous advantages for businesses. It improves accuracy by reducing manual data entry errors, enhances efficiency by automating processes, and accelerates the exchange of information, leading to shorter order cycles and faster response times.
In this article, we will delve deeper into the basics of EDI, including its benefits, how it works, and its role in streamlining supply chain processes. So, let’s get started and uncover the power of EDI in transforming business operations.
**How does EDI work?**
EDI works by establishing a direct connection between trading partners’ computer systems. Instead of manually entering and processing data, businesses can automate the exchange of information through EDI. This is achieved by mapping data from internal systems to the required format and sending it electronically to the recipient.
The process begins with the creation of a business document, such as a purchase order or an invoice, in the sender’s system. The document is then converted into the standardized EDI format and transmitted to the recipient. The recipient’s system receives and processes the EDI message, extracting the relevant data and integrating it into their internal systems.
EDI communication can take place through various methods, including Value-Added Networks (VANs), direct connections (AS2, FTP, SFTP), or web-based EDI solutions. These methods ensure secure transmission and adherence to agreed-upon standards, maintaining data integrity and confidentiality.
Implementing EDI requires collaboration between trading partners to establish and maintain the necessary connections and define the message standards and document formats. Once the EDI system is set up, businesses can enjoy the benefits of seamless data exchange, improved efficiency, and enhanced collaboration.
Advantages of using EDI
Implementing EDI offers numerous advantages for businesses. Firstly, it improves accuracy by reducing manual data entry errors. With EDI, information is entered into the system only once, eliminating the need for rekeying and minimizing the risk of human errors. This leads to increased data quality and reduces the likelihood of costly mistakes.
Secondly, EDI enhances efficiency by automating processes. Manual handling of business documents can be time-consuming and prone to delays. By automating the exchange of information, EDI eliminates the need for manual intervention, enabling faster processing and reducing cycle times. This not only saves time but also improves overall productivity.
Thirdly, EDI accelerates the exchange of information, leading to shorter order cycles and faster response times. With traditional paper-based transactions, delays can occur due to physical handling, mailing, and manual processing. EDI eliminates these bottlenecks by enabling instant transmission and processing of data, ensuring timely responses and improved customer satisfaction.
Furthermore, EDI enables better visibility and tracking of transactions. Businesses can easily track the status of orders, invoices, and other documents, enabling proactive management and real-time monitoring. This visibility improves supply chain efficiency and allows for better decision-making based on accurate and up-to-date information.
In addition, EDI promotes better collaboration between trading partners. By standardizing the format and structure of business documents, EDI ensures seamless communication and eliminates the need for manual reconciliation of different formats. This streamlines processes and fosters stronger relationships between businesses, leading to improved supply chain management and increased customer satisfaction.
Conclusion
In conclusion, Electronic Data Interchange (EDI) has revolutionized the way businesses exchange information. By enabling the electronic interchange of business documents in a standardized format, EDI streamlines operations, improves accuracy, enhances efficiency, and accelerates the exchange of information. It offers numerous benefits for businesses of all sizes and across various industries, from improved supply chain management to enhanced collaboration with trading partners.
Understanding the basics of EDI, including how it works, its advantages, key components, and implementation considerations, is crucial for businesses looking to leverage its power. By embracing EDI and integrating it into their operations, businesses can optimize their supply chain processes, reduce costs, and gain a competitive edge in today’s fast-paced digital landscape. So, explore the possibilities of EDI and unlock the potential for transformation in your business.

## Introduction
Imagine a mystical night in the Enchanted Forest where shadows weave spells of silence and the moon bathes the leaves in silver whispers. In this magical realm, you take on the role of the Forest's Arcane Hunter, a master of ancient texts and echoic spells. Your quest is to harness the power of Linux commands to unveil secrets hidden in plain sight and to bring to light the spells encoded within arcane texts.
Armed only with your knowledge and the Linux terminal, you shall embark on a series of challenges to demonstrate proficiency in manipulating text displays. Your objective is to learn and master the `echo` command—to create messages, cast spells, and unveil charms in the terminal's dark canvas.
Prepare to step into a world where each keystroke unravels a part of the greater mystery that is the Enchanted Forest's nocturnal chorus. Are you ready to become the linguistic artisan of this wilderness? Your journey begins now.
## The Echo Spell of Greeting
In this step, you will cast your first echo spell by sending a greeting to the forest. The `echo` command in Linux is used to display a line of text to the terminal output. Before unleashing your first spell, you must prepare the script that contains your words of magic.
Open the terminal and type the following command:
```bash
echo "Greetings, Enchanted Forest! I am the Arcane Hunter."
```
The expected result will be:
```
Greetings, Enchanted Forest! I am the Arcane Hunter.
```
## Echoing the Charm of Paths
For this step, use the power of `echo` to reveal your current path in the forest, the one known as the "present working directory." The charm requires you to append this information within a text file named `path_charm.txt`. Here you shall capture the essence of the path and keep it for later incantations.
To achieve this, execute the following command in the terminal:
```bash
cd ~/project
echo "Current path: $(pwd)" > path_charm.txt
```
After running it, look inside `path_charm.txt` using `cat path_charm.txt` to see the following content:
```text
Current path: /home/labex/project
```
## Summary
In this lab, you embarked on an enchanting journey through the Enchanted Forest, casting echo spells and learning the fundamentals of displaying text in the Linux environment. Starting with a simple greeting, you wove your way through revealing your path, all using the `echo` command as your guiding spell.
My design logic was to create an engaging, gamified scenario encouraging the learner to connect emotionally to the lab activities, thus enhancing memory retention and making the learning process enjoyable. I hope this lab has provided you with the confidence to continue exploring and mastering the Linux command line, preparing you for more complex incantations within this magical forest of knowledge.

1,891,142 | Encapsulate What Varies (EWV) Principle: A Pragmatic Approach | Applying the Encapsulate What Varies (EWV) principle helps create maintainable, flexible, and... | 0 | 2024-06-17T11:47:35 | https://dev.to/muhammad_salem/encapsulate-what-varies-ewv-principle-a-pragmatic-approach-2p3f |
Applying the Encapsulate What Varies (EWV) principle helps create maintainable, flexible, and adaptable software systems. The essence of this principle is to identify aspects of your application that are likely to change and encapsulate them in such a way that these changes do not affect the core, stable parts of your system. Let's explore this with real-world examples and practical steps.
### Understanding the Problem Domain
**Domain Understanding**: The first step is to deeply understand the problem domain and the core functionalities of your application. This involves:
- Analyzing requirements
- Identifying key use cases
- Understanding the data involved
**Example**: Suppose you are developing an e-commerce platform. Core functionalities might include product catalog management, order processing, and user authentication.
### Identifying Stable Core and Variable Aspects
**Identify Stable Core**: Pinpoint the functionalities that remain consistent throughout the application's lifecycle.
**Example**: In our e-commerce platform, the core order processing logic, such as adding items to the cart, calculating totals, and managing user sessions, remains stable.
**Look for Variability**: Analyze areas where functionalities might change due to evolving requirements.
**Example**: Payment methods (credit card, PayPal, cryptocurrencies), shipping options (standard, express, international), and promotional discount rules are likely to change over time.
### Techniques for Identifying Variable Aspects
1. **Scenario Analysis**: Consider different use cases and identify if some aspects of the application behave differently.
2. **Future-Proofing**: Think about potential future requirements and how the application might need to adapt.
3. **Non-Functional Considerations**: Reflect on performance, scalability, or security factors.
4. **External Dependencies**: Recognize dependencies on external systems or data sources.
### Real-World Example: Payment Processing
#### Stable Core: Order Processing
```csharp
public class OrderService
{
public void ProcessOrder(Order order)
{
// Stable core logic for processing an order
// ...
}
}
```
#### Variable Aspect: Payment Method
```csharp
public interface IPaymentProcessor
{
void ProcessPayment(Order order);
}
public class CreditCardPaymentProcessor : IPaymentProcessor
{
public void ProcessPayment(Order order)
{
// Logic for processing credit card payment
// ...
}
}
public class PayPalPaymentProcessor : IPaymentProcessor
{
public void ProcessPayment(Order order)
{
// Logic for processing PayPal payment
// ...
}
}
public class PaymentService
{
private readonly IPaymentProcessor _paymentProcessor;
public PaymentService(IPaymentProcessor paymentProcessor)
{
_paymentProcessor = paymentProcessor;
}
public void ProcessPayment(Order order)
{
_paymentProcessor.ProcessPayment(order);
}
}
```
### Benefits of Encapsulating What Varies
1. **Increased Maintainability**: Easier to modify or extend variable aspects without affecting core logic.
2. **Improved Flexibility**: The application can adapt to changing requirements more readily.
3. **Enhanced Reusability**: Stable core components can be reused across different projects or integrations.
4. **Better Testability**: Individual variable components can be tested in isolation.
### Tips for Pragmatic Implementation
1. **Start with Core**: Focus on building the stable core functionalities first.
2. **Identify Clear Boundaries**: Clearly define the interfaces between stable and variable aspects.
3. **Use Abstraction Layers**: Employ well-defined interfaces to separate variable aspects from the core.
4. **Don't Over-engineer**: Focus on areas where variability is evident. Avoid over-complicating the design.
5. **Refactor as Needed**: As the application evolves, refactor to identify new areas of variability and encapsulate accordingly.
### Example: Shipping Options
#### Stable Core: Shipping Logic
```csharp
public class ShippingService
{
public void ShipOrder(Order order)
{
// Stable core logic for shipping an order
// ...
}
}
```
#### Variable Aspect: Shipping Methods
```csharp
public interface IShippingMethod
{
void Ship(Order order);
}
public class StandardShipping : IShippingMethod
{
public void Ship(Order order)
{
// Logic for standard shipping
// ...
}
}
public class ExpressShipping : IShippingMethod
{
public void Ship(Order order)
{
// Logic for express shipping
// ...
}
}
public class ShippingService
{
private readonly IShippingMethod _shippingMethod;
public ShippingService(IShippingMethod shippingMethod)
{
_shippingMethod = shippingMethod;
}
public void ShipOrder(Order order)
{
_shippingMethod.Ship(order);
}
}
```
### Final Thoughts
By adhering to the EWV principle, you can design software that is both robust and adaptable to change. This approach is particularly valuable in rapidly evolving domains where requirements can change frequently. The key is to deeply understand the problem domain, identify the stable core functionalities, and encapsulate the aspects that are likely to change. This not only makes your codebase more maintainable and flexible but also enhances testability and reusability.
Encapsulating what varies is a cornerstone of good object-oriented design and leads to high-quality code that stands the test of time. | muhammad_salem | |
1,891,141 | Bridging the Gap: Integrating Responsible AI Practices into Scalable LLMOps for Enterprise Excellence | Responsible LLMOps: Integrating Responsible AI Practices into LLMOps ... | 0 | 2024-06-17T11:47:30 | https://dev.to/emma_in_tech/bridging-the-gap-integrating-responsible-ai-practices-into-scalable-llmops-for-enterprise-excellence-19k3 | ai, llmops, aiops, machinelearning | ### Responsible LLMOps: Integrating Responsible AI Practices into LLMOps
#### Introduction
The rapid adoption of Large Language Models (LLMs) in enterprises has opened new avenues for AI-driven solutions. However, this enthusiasm is often tempered by challenges related to scaling and responsibly managing these models. The growing focus on Responsible AI practices highlights the need to integrate these principles into LLM operations, giving rise to the concept of Responsible LLMOps. This blog explores the intricacies of combining LLMOps with Responsible AI, focusing on addressing specific challenges and proposing solutions for a well-governed AI ecosystem.
#### Understanding LLMOps
LLMOps, an extension of MLOps, deals specifically with the lifecycle management of LLMs. Unlike traditional MLOps, which focuses on structured data and supervised learning, LLMOps addresses the complexities of handling unstructured data, such as text, images, and audio. This involves managing pre-trained foundational models and ensuring real-time content generation based on user inputs. Key aspects include:
1. **Unstructured Data**: LLMOps primarily deals with large volumes of unstructured data, necessitating robust data management strategies.
2. **Pre-trained Models**: Instead of building models from scratch, LLMOps often involves fine-tuning pre-trained models on domain-specific data.
3. **Human Feedback Loops**: Continuous improvement of LLMs requires integrating human feedback to enhance response quality and reduce biases.
#### LLMOps Architectural Patterns
The implementation of LLMOps can vary based on the use-case and enterprise requirements. Here are five prevalent architectural patterns:
1. **Black-box LLM APIs**: This model involves interacting with LLMs through APIs, such as ChatGPT, for tasks like knowledge retrieval, summarization, and natural language generation. Prompt engineering is crucial in this scenario to guide the LLMs towards generating accurate responses.
2. **Embedded LLM Apps**: LLMs embedded within enterprise platforms (e.g., Salesforce, ServiceNow) provide ready-to-use AI solutions. Data ownership and IP liability are critical considerations here.
3. **LLM Fine-tuning**: Fine-tuning involves adapting a pre-trained LLM with enterprise-specific data to create domain-specific Small Language Models (SLMs). This approach requires access to model weights and is often more feasible with open-source models.
4. **Retrieval Augmented Generation (RAG)**: RAG provides context to LLMs by retrieving relevant documents, thereby grounding the responses. This method is less computationally intensive than fine-tuning.
5. **AI Agents**: Advanced AI agents like AutoGPT can perform complex tasks by orchestrating multiple LLMs and AI applications, following a goal-oriented approach.
#### Integrating Responsible AI into LLMOps
Responsible AI practices must be embedded within the LLMOps framework to ensure ethical and reliable AI solutions. This integration involves addressing various dimensions, including data quality, model performance, explainability, and data privacy.
1. **Data Quality and Reliability**
- Ensuring consistent and accurate data for training and fine-tuning LLMs is critical. This includes monitoring data pipelines and eliminating biases to improve the trustworthiness of the models.
- Example: In a chatbot for an airport, integrating RAG architecture can help provide accurate flight status and ticket availability by grounding the responses in real-time data.
2. **Model Performance and Reproducibility**
- Evaluating model performance during both training and inference phases ensures that LLMs meet expected standards. Metrics like Perplexity, BLEU, and ROUGE, along with human evaluations, are essential for assessing model quality.
- Example: For an AI product summarizing social media campaign responses, metrics such as BLEU and ROUGE can measure the quality of generated insights.
3. **Model Explainability**
- Explainability tools and frameworks, such as Chain of Thought (CoT), help elucidate how LLMs arrive at their conclusions, enhancing transparency and trust.
- Example: In a medical insurance chatbot, providing explanations alongside claim status helps users understand the rationale behind decisions.
4. **Data Privacy**
- Safeguarding the privacy of both enterprise data used for fine-tuning and user data provided as prompts is crucial. Implementing robust privacy controls and adhering to regulatory guidelines ensures compliance and protection.
- Example: Ensuring data privacy in a cloud-based LLM platform involves setting up secure environments and access controls for sensitive information.
#### Conclusion
The fusion of Responsible AI practices with LLMOps creates a robust framework for deploying scalable and ethical AI solutions in enterprises. By addressing specific challenges related to data quality, model performance, explainability, and privacy, organizations can build a well-governed AI ecosystem. This integrated approach not only accelerates LLM adoption but also future-proofs AI investments, ensuring they remain relevant and effective as the technology landscape evolves.
Responsible LLMOps is not just about managing AI lifecycles; it’s about embedding ethical principles at every stage of AI deployment. By doing so, enterprises can harness the full potential of LLMs while maintaining accountability and trust with their stakeholders.
---
As enterprises increasingly adopt Large Language Models (LLMs), integrating Responsible AI practices into LLMOps becomes essential for ethical and scalable AI solutions. This blog explores the challenges and solutions in combining these frameworks to ensure a well-governed AI ecosystem.

1,891,140 | Mastering Async/Await in JavaScript Like a Pro! | 1. Introduction to Async/Await Async/Await is a much more modern JavaScript syntax for... | 27,607 | 2024-06-17T11:47:08 | https://dev.to/hkp22/mastering-asyncawait-in-javascript-like-a-pro-33h0 | webdev, javascript, programming, react | ### 1. Introduction to Async/Await
Async/Await is a much more modern JavaScript syntax for dealing with asynchronous operations of a program in a much smoother and more intuitive way. It was launched within ECMAScript 2017, or ES8, that eases working with Promises and gives asynchronous-looking and-behaving, synchronous-like code.
{% youtube TeX-ecZH7Z8 %}
👉 **[Download eBook - JavaScript: from ES2015 to ES2023](https://qirolab.gumroad.com/l/javascript-from-es2015-to-es2023)**
.
#### Importance in Modern JavaScript Development
Asynchronous programming is definitely important in JavaScript, most particularly in tasks like API calls, file handling, and timers. Async/await also enhances readability and many other maintainability aspects of the code; hence, easier writing and debugging.
#### Basic Syntax
The async keyword applies the definition of an asynchronous function, while the await keyword is then applied to cause the function execution to actually pause until a promise has been resolved.
```javascript
async function example() {
let value = await someAsyncFunction();
console.log(value);
}
```
---
### 2. Understanding Asynchronous Programming
#### Synchronous vs. Asynchronous Operations
- **Synchronous:** The operations are executed one after the other; each subsequent operation is blocked until the previous one is completed.
- **Asynchronous:** The operations can run irrespective of the main program's flow; the program can continue with other tasks in its execution.
#### Callbacks and Promises as Predecessors
- **Callbacks:** A function is passed as an argument to another function, which is executed once an asynchronous operation is complete. It can result in "callback hell."
- **Promises:** It is an object that represents the eventual completion or failure of an operation. This approach makes the code more readable compared to callbacks, but sometimes it can also lead to complexity and mess.
---
### 3. Async Functions
#### Definition and Usage
An async function is a function declared using the async keyword. It enables you to write the Promise-based code as much simpler async/await syntax, and you can write async in it, which suspends the execution until a Promise resolves.
#### How to Declare an Async Function
```javascript
async function fetchData() {
let response = await fetch('https://api.example.com/data');
let data = await response.json();
return data;
}
```
---
### 4. Await Keyword
#### Definition and Usage
The `await` keyword is used to wait for a Promise to resolve. It can only be used inside an `async` function.
#### How it Works within Async Functions
When `await` is encountered, the async function pauses execution until the Promise settles. The resolved value of the Promise is then returned.
```javascript
async function getUser() {
let user = await fetchUserFromDatabase();
console.log(user);
}
```
---
### 5. Error Handling
#### Using Try/Catch with Async/Await
Errors in async functions can be handled using try/catch blocks, similar to synchronous code.
```javascript
async function fetchData() {
try {
let response = await fetch('https://api.example.com/data');
let data = await response.json();
return data;
} catch (error) {
console.error('Error fetching data:', error);
}
}
```
#### Common Pitfalls and How to Avoid Them
- **Forgetting to use `await`:** Leads to unhandled Promises.
- **Using `await` outside of `async` functions:** Causes syntax errors.
---
### 6. Practical Examples
#### Fetching Data from an API
```javascript
async function getApiData() {
let response = await fetch('https://api.example.com/data');
let data = await response.json();
console.log(data);
}
```
#### Sequential vs. Parallel Execution
- **Sequential Execution:**
```javascript
async function sequentialTasks() {
let result1 = await task1();
let result2 = await task2();
console.log(result1, result2);
}
```
- **Parallel Execution:**
```javascript
async function parallelTasks() {
let [result1, result2] = await Promise.all([task1(), task2()]);
console.log(result1, result2);
}
```
---
### 7. Advanced Topics
#### Async/Await with ES6 Modules
Async functions can be exported and imported just like any other functions in ES6 modules.
```javascript
// module.js
export async function fetchData() {
let response = await fetch('https://api.example.com/data');
return await response.json();
}
// main.js
import { fetchData } from './module.js';
fetchData().then(data => console.log(data));
```
#### Combining with Other Asynchronous Patterns
You can combine async/await with other Promise methods like `Promise.all` for concurrent execution.
```javascript
async function loadData() {
let [users, posts] = await Promise.all([fetchUsers(), fetchPosts()]);
console.log(users, posts);
}
```
---
### 8. Conclusion
#### Summary of Key Points
- [Async/await](https://qirolab.com/posts/javascript-asyncawait-writing-clean-and-efficient-asynchronous-code) provides a more readable and maintainable way to handle asynchronous operations.
- Async functions return Promises, and `await` pauses execution until the Promise resolves.
- Error handling is straightforward with try/catch.
- Practical use cases include API calls and concurrent task execution.
#### Best Practices
- Always use `await` inside `async` functions.
- Handle errors gracefully with try/catch.
- Use `Promise.all` for parallel execution to improve performance.

This is because ESG metrics help investors assess the broader impact of a company’s operations, extending beyond mere financial performance.
For those seeking data on a company's positive impact on local communities, [ESG services](https://www.sganalytics.com/esg-services/) offer valuable insights. These services provide comprehensive reports based on data-driven surveys concerning ESG compliance standards. ESG audits, in particular, play a crucial role in enabling informed investment decisions and effective portfolio management strategies. Through these audits, investors can monitor whether a firm is delivering on its SDG promises. Additionally, investors can ensure their capital supports businesses that prioritize fair wages and respect for employees.
How to Get Started with ESG Investing
1. Identify Key Metrics
The initial step in ESG investing is to determine which metrics are most important to you. Investors need to identify the ESG metrics that align with their values, such as forest preservation or tax transparency, before selecting a stock or asset class. It's essential to recognize that different metrics carry varying significance across industries. For example, carbon and greenhouse gas (GHG) emission risks will differ between data centers, agricultural businesses, and construction firms.
Organizations looking to attract sustainability-focused investors can greatly benefit from [ESG consulting](https://www.sganalytics.com/esg-consulting/). Consultants help companies understand what investors consider an ESG-first enterprise and how they can enhance their operations to meet these expectations.
2. Set Realistic Goals
Adopting greener resources and production technologies can be financially challenging for businesses, especially during the initial stages of the energy transition. Therefore, investors, regulators, and entrepreneurs must rely on real-world data to estimate the progress rate of compliance improvement initiatives.
An organization or exchange-traded fund (ETF) may lose investors if its compliance milestones seem too distant. Hence, regulators involved in policy changes that affect ESG dynamics need to consider the timeframe businesses will require to modify their operations.
3. Mitigate Greenwashing Risks
Greenwashing, where companies falsely advertise themselves as eco-friendly or socially responsible, poses a significant challenge in ESG investing. Investors must be vigilant against such deceptive practices. For example, a company might claim it opposes discriminatory practices but fails to act when an employee faces workplace harassment. Similarly, an energy distributor might not reduce its reliance on coal and petroleum derivatives despite claiming to support green energy.
To combat greenwashing, investors and fund managers should cross-verify the sustainability claims made by target companies during press releases or marketing campaigns.
4. Utilize Multiple ESG Rating Frameworks
To validate a corporation’s SDG commitments, investors can use rating mechanisms based on multi-variate performance analytics. Numerous sustainability accounting frameworks exist today. For instance, the Global Reporting Initiative (GRI) provides sector-specific modules, meaning an agricultural business will use different GRI standards than technology or finance firms.
Investors can start comparing ESG scores through online databases offering preliminary insights into how various brands and ETFs compete. More detailed data is often available through paid platforms or experienced consultants.
The Importance of ESG Criteria
ESG criteria empower investors to evaluate the ecological and social risks associated with a company's operations. Fund managers and financial institutions can adopt a more objective approach to stock screening by leveraging industry-relevant assistance. This not only ensures a responsible investment strategy but also aligns with global sustainability trends.
Overcoming Greenwashing Challenges
While it can be challenging for sustainability investors to overcome greenwashing risks, extensive analytical models can provide valuable support. By referring to multiple sustainability accounting frameworks or databases, investors can verify a firm's compliance ratings. This comprehensive approach is essential for starting with ESG investing.
However, manual inspection of ESG ratings can be time-consuming, and these ratings often change due to mergers and new projects. Therefore, partnering with data providers capable of automating compliance tracking, controversy analytics, and carbon credit assessments is crucial for efficient ESG investing.
Conclusion
ESG investing serves as a powerful approach that allows investors to consider the environmental, social, and governance impacts of their investment choices. By focusing on key metrics, setting realistic goals, mitigating greenwashing risks, and employing multiple ESG rating frameworks, investors can make informed and responsible decisions.
Partnering with data providers for automated compliance tracking and analysis further streamlines the process, ensuring investors remain aligned with their sustainability objectives while navigating the dynamic ESG landscape. Ultimately, ESG investing is not solely about financial returns; it is about contributing to a sustainable future by supporting companies that prioritize responsible and ethical practices. This approach not only drives positive societal change but also fosters long-term economic resilience and stability. | linda0609 | |

We all know Oracle releases quarterly updates, and the release of the year is here: “Oracle Financials 24A Release.” This brings a variety of new features and upgrades to improve function- ality & expedite procedures, enhance workflows, empower data driven decision-making, and im- prove user experience. This update offers a plethora of interesting new features and chan- ges. As with any significant update, careful tes- ting is necessary to guarantee a seamless tran- sition and prevent any glitches.
Insufficient testing and poorly executed modifi- cations might risk business continuity and per- haps cause system outages. Oracle clients re- quire a thorough testing plan for the Oracle Cloud Financials 24A update to prevent this. Compre- hensive testing, enabled by test automation, allows users to focus on maximizing the new features that Oracle has made available.
**What’s New in the Oracle 24A Release**?
**Human Capital Management**
Additional features added by Global Human Resources include Oracle Grow template integration, longer task expiry, journey editing, and new task kinds. Updates to hiring procedures, roles, and compensation features, along with pages created by VBS and mass download filters, are among the elements of the Redwood experience.
Redwood Talent Management offers AI-powered features such as feedback generation, AI-driven profile construction, AI-enabled goal setting, and enhanced performance evaluation.
Recruiting brings new developments in AI and enhances the internal candidate experience. Talent Management offers Suggested Successors and Best Features for the Redwood succession planning process. AI-powered goal development is included in goal management. Opportunity Marketplace adds fresh functionality, and Learning offers more options and automated suggestions.
**Financials Supply Chain Management**
The Oracle Financials 24A release enhances sourcing, limited availability, supplier qualification management, procurement contracts, external purchases, item replacement, supply chain management, and sourcing.
**Some Technical Updates**
The Oracle financials 24A upgrade includes improvements to HCM, recruiting, Talent Management, learning, and Absence Management. It also adds a new topic area to Workforce Scheduling, and an expanding characteristic is Global Payroll.
**Functional Changes from the Oracle Cloud Financials 24A Release**
**Payables**: A new report called the Payables Exception Report makes it possible to examine invoice exceptions categorized by exception type and to link particular exceptions to resources for analysis and resolution. The campaign manager can now choose suppliers for dynamic discounting campaigns based on currency, payment terms, and methods. This maximizes campaign efficacy by allowing the manager to select suppliers with more extended payment periods.
**Receivables**: Users can sweep invalid Receivables Transactions to a later Accounting Period by utilizing the programs "Review transaction information without sweep" and "Sweep transactions to next accounting period." Receivables transactions can have their third-party tax registration numbers automatically assigned to them at the time of transaction formation. When creating a Receivables transaction, the user can automatically give the legal entity third-party tax registration number to the bill-to-customer.
**General Ledger**: Attachments Audit can be enabled on the journal attachments files to track and evaluate all attachment actions, including download, update, deletion, and insert/check-in. A subset of the values assigned to the primary ledger and associated legal entities in the primary balancing segment can also be applied to the Secondary Ledger. In situations when the primary ledger represents several legal entities or nations, this effectively allows organizations to populate subsidiary ledgers for particular legal entities.
**Expected Financials**: Users now have the ability to auto-post journals across all ledgers and assign them the data access set. This will streamline the journal entry procedure, minimize manual efforts, and provide accuracy in financial reporting.
**Taxes**: To streamline tax compliance procedures, Oracle has integrated Avalara's automatic tax partner integration. This integration guarantees compliance with tax laws, expedites tax computations, and lowers error rates.
**Expenses**: To ensure accuracy and compliance, costs resubmitted are evaluated using audit standards to identify duplicate expenses. Organizations can reduce fraudulent activity and improve cost management procedures by automating the detection of duplicate payments.
**What are the best practices for testing the Oracle Cloud Financials 24A Release**?
- The testing parameters decide which tests are crucial and which are not during the quarterly Oracle Financials Cloud update.
- Implement sanity testing as soon as possible to ensure business continuity.
- Determine which business procedures related to finances should be automated and which ones still require manual testing.
- To demonstrate the variations between releases, use impact analysis reports.
**Technological improvements anticipate with the Oracle Cloud Financials 24A Release**
- You can download and install the most recent version of the Oracle ADF Desktop Integration add-in, which is version 5.1.5.26625, right now.
- With the Oracle 24A release, deprecated Business Intelligence View Objects (BIVOs) can no longer be extracted using BI Cloud Connector.
- Additional data items will be included in the Receivables XML invoice extract as required by different national legislation. Therefore, there is less need for implementation-specific modification.
- Using the Oracle Financials 24A release, alternative payer name mapping rules for Japanese client bank accounts can be bulk-uploaded via the Zengin Format for Japan REST API.

The significance of security and compliance in the creation of financial software in the current digital era cannot be emphasizedemphasised. Financial software is being used more and more, thus it's critical to make sure these systems are safe and legal.
If this isn't done, there may be monetary losses, legal repercussions, and reputational harm. For financial software development to achieve security and compliance, it is crucial to comprehend best practices and rules.
The best practices and rules that financial institutions should adhere to to guarantee the security and compliance of their software development projects will be discussed in this article. Now let's get started with the significance of security inito buildingbuild a financial planning software.
## What is the Importance of Building a Secure Financial Software?
Financial firms shouldhave an obligation to safeguard their clients' sensitive information because the financial sector is heavily regulated. Any security breach may lead to large monetary losses, harm to one's reputation, and legal ramifications.
In addition, noncompliance may result in expensive fines, legal repercussions, and reputational harm to the organizationorganisation. The digital age and changing client needs are forcing financial institutions to embrace new technology, which raises the risk of non-compliance and security breaches. Furthermore, given how quickly technology is being adopted, it is even more important to give security and compliance procedures top priority.
## Practices for Secure Financial Software Development- Easy Points to Remember
Building finance software requires careful attention to security and compliance. Financial organizations can safeguard their software and data from security breaches and non-compliance by adhering to several best practices. However, not all of them are recommended by professionals or helpful for the development of financial software.
As a result, we have listed below the top 8 practices for security and compliance followed by the best financial software development company to create a robust financial software.
## Keeping Up Regulatory Compliance
To guarantee compliance, financial institutions have to abide by regulatory requirements and rules. These regulations may include GDPR, PCI DSS, and other banking industry-specific guidelines. To ensure adherence to these requirements, compliance entails putting in place the proper security measures, keeping an eye on systems regularlyon a regular basis, and performing audits.
For instance, toin order to make sure that its clients are not engaged in any unlawful activity, banks are required to adhere to the Anti-Money Laundering (AML) legislation.
## Multiple-Factor Verification
For identification and authorization, a username and password areis important that to verifyverifies a user. In multi-factor authentication, the client's identity (biometrics), possessions (hardware tokens, one-time codes), and knowledge (password) can all be used.
Use dynamic PIN codes, one-time passwords, calls, push alerts, fingerprints, face recognition, or retinal scans, for instance, to integrate security into financial apps.
A lot of fintech businesses employ adaptive or risk-based authentication. This means that toin order to identify suspicious activity, the system examines data entry, registered devices, geolocation, access timings, and other behavioralbehavioural aspects.
## Permissions and Roles
To ensure that data access is secure in a financial application, user roles and permissions must be specified. Think about positions like manager, IT specialist, administrator, client, support service, etc.
RBAC role settings and permission organizationorganisation are available for use. The ACL approach, which provides users with a list of all operations, is an alternative. This makes it possible to identify each user as having access to particular information and features. Customers and unapproved staff won't be able to see too much at the same time.
Establish access control guidelines for client-side caching, file permissions, and insecure identifiers. It would be ideal to restrict rights to the barest minimum required and to permit their expansion when circumstances demand.
## Performing Detailed Risk Assessments
Regular, in-depth risk evaluations are crucial for detecting potential flaws in financial software. The evaluations ought to appraise the probability and possible consequences of diverse security risks and offer suggestions for mitigating these hazards.
A financial organizationorganisation might, for instance, carry out a risk assessment to find any weaknesses in its online banking system and take appropriate action to fix them.
## Digitising Confidential Data
The process of transforming data into a coded language to prevent unwanted access is known as encryption. Sensitive data, including account numbers, transaction data, and personal information, should be encrypted by financial institutions.
For instance, end-to-end encryption could be used by a bank to guard against possible breaches involving the transaction data of its clients.
## Regular Penetration Testing and Security Audits
Financial organizations can find possible security flaws in their systems and fix them before they are exploited with the aid of routine security audits and penetration tests. These audits may include evaluations from the inside as well as the outside, together with suggestions for enhancing security.
For instance, a financial institution may contract with an outside security company to audit and test its systems for vulnerabilities.
## Assurance of Quality
Maintaining strong finance app security standards throughout the development lifecycle requires appropriate QA. Determining and evaluating requirements, formulating potential business scenarios, testing functionality and databases, establishing API specifications, authorizingauthorising and authenticating users, and user approval are all included in the process.
To find and address vulnerabilities, regular security assessments are crucial. Remember to perform penetration testing as well to evaluate application resilience and replicate real-world threats.
## Code Obfuscation
Clones of banking apps are frequently made by cybercriminals to obtain user information. You should use code obfuscation to protect yourself. This includes adding unnecessary or meaningless code to the program binary, eliminating potentially exposed metadata, encrypting part or all of the code, and labeling classes and variables with meaningless labels.
## Conclusion
In conclusion, any finance company's business and reputation are greatly influenced by security and compliance. Respecting security and compliance policies is essential to preventing money losses, legal repercussions, and harm to one's reputation.
To achieve security and compliance in financial software development, it is imperative to follow the above-discussed best practices, which include identifying and prioritizing compliance requirements, creating explicit policies and procedures, educating staff members on security protocols, and tracking and reporting on security and compliance activities.
Additionally, we strongly advise that you closely adhere to the best software development practices and consult with a [financial software development company](https://www.cmarix.com/finance-and-banking.html) that specializes in creating financial software while making plans for financial software development. Make sure they follow these instructions, as this guarantees the safety and adherence to the software.

1,891,121 | 🤯Deep vs Shallow cloning ??? | How to determine? Shallow Copy Criteria: Only the top-level properties are... | 0 | 2024-06-17T11:21:11 | https://dev.to/__khojiakbar__/deep-vs-shallow-cloning--40ln | javascript, deep, shallow, cloning |
# How to determine?
## Shallow Copy
**Criteria:**
* Only the top-level properties are copied. Nested objects are copied by reference.
**Indicators:**
* If modifying a nested object in the copied object also changes the original object's nested object, it is a shallow copy.
Both the original and copied objects' nested objects will have the same reference.
```
let original = {
name: "Alice",
address: { city: "Wonderland" }
};
let shallowCopy = { ...original }; // Shallow copy
shallowCopy.address.city = "New Wonderland";
console.log(original.address.city); // Output: "New Wonderland"
console.log(shallowCopy.address.city); // Output: "New Wonderland"
console.log(original.address === shallowCopy.address); // Output: true
```
## Deep Copy
**Criteria:**
- All properties, including nested objects, are fully copied. No references to the original nested objects are retained.
**Indicators:**
- If modifying a nested object in the copied object does not change the original object's nested object, it is a deep copy.
- The original and copied objects' nested objects will have different references.
```
let original = {
name: "Alice",
address: { city: "Wonderland" }
};
let deepCopy = JSON.parse(JSON.stringify(original)); // Deep copy
deepCopy.address.city = "New Wonderland";
console.log(original.address.city); // Output: "Wonderland"
console.log(deepCopy.address.city); // Output: "New Wonderland"
console.log(original.address === deepCopy.address); // Output: false
```
## Steps to Check Copy Type
### 1. Create Original Object:
Define an object with nested properties.
```
let original = {
name: "Alice",
address: { city: "Wonderland" }
};
```
### 2. Make a Copy:
Create a copy using your chosen method.
```
let copy = { ...original }; // For shallow copy
// or
let copy = JSON.parse(JSON.stringify(original)); // For deep copy
```
### 3. Modify Nested Property in Copy:
Change a nested property in the copied object.
```
copy.address.city = "New Wonderland";
```
### 4. Check Original Object:
Compare the nested property in the original object.
```
console.log(original.address.city); // Check if this has changed
```
### 5. Compare References:
Check if the nested objects are the same reference.
```
console.log(original.address === copy.address); // true for shallow, false for deep
```
## Summary
**Shallow Copy:**
* Top-level properties are copied.
* Nested objects are shared (same reference).
* Modifying nested objects in the copy affects the original.
**Deep Copy:**
* All properties, including nested objects, are fully copied.
* Nested objects are not shared (different references).
* Modifying nested objects in the copy does not affect the original.
By following these steps and criteria, you can determine whether an object copy is shallow or deep.

1,890,500 | Ho we built Ammirator. The OnlyFans competitor | Our journey began a year ago when we started thinking about building a platform for content creators... | 0 | 2024-06-17T11:18:22 | https://dev.to/ammirator/ho-we-built-ammirator-the-onlyfans-competitor-26e1 | web3, ethereum, javascript, kubernetes | Our journey began a year ago when we started thinking about building a platform for content creators that would work fully with crypto and have the lowest platform fee in the industry (**just 10%**), and that's when we started to build [Ammirator](https://ammirator.com).
We choose crypto because the problem with traditional payment providers is that they may block payments or block your account on their side if your platform contains content they do not like, on top of that they take a fee from each transaction from every subscription or tip, so instead of this money to go to content creators these go to payment providers without them doing anything at all.
To have a truly independent platform we decided to use Ethereum as our currency and all the transactions to be sent directly to the blockchain without having any payment provider in the middle.
We also needed somewhere to store our data, and that place should be fully controllable by us and be a safe one, and not depend on third parties.
We never had the question "Which Database to choose", we were ok with any opensource solution the main question was how to store data in a way that it is available on multiple nodes/machines so that in case some node is shut down or attacked then the database container moves to a new node and data is available there instantly.
For this purpose we picked Longhorn, this is an open-source tool that can replicate your data from one disk to another on a totally different machine.
You guessed it right all mentioned above is most probably possible just with Kubernetes clusters at least in an easy way.
Since we wanted our platform to not depend on third parties we can't afford to use Kubernetes solutions like ECS or others.
All the tools we use are deployed on bare metal and are fully controlled and managed by us.
Having these infrastructure benefits from the very start is not enough to win competitors like Onlyfans, so we spent the whole year building a lot of features that should help our content creators monetize their content and bring happiness to their fans.
We have features like paid subscriptions, tips, paid posts, and basic things like chats with fans, suggestions, etc.
Now having all the infrastructure controlled by us and having all the data on our side, we basically can modify the platform fee we take from creators to a minimum at any time just to cover nodes/machines costs and developers' time.
Our platform fee consists **just 10%** which is the lowest one we know in the industry.
Most of the similar platforms have a fee of 20% and from a minimal subscription of 5$ they do not really make money because 20% is just 1$ and most of this goes to the payment provider which also takes a fee from each transaction and the platform remains just with less than a half from there, and on top of that the payment providers dictate them what kind of content they are allowed or not to post.
Because of these poor decisions made by the founders and developers of these platforms, have to lose also content creators who have to pay 20% of their money, which is more than some taxes in some countries for a minute.
At [Ammirator](https://ammirator.com) we do not have all these problems, and we can truly focus on features and creators' happiness while delivering a platform that gives all the necessary tools for them to interact with their fans.
This allows us to become a true competitor for most of content creators' platforms out there, and who knows maybe in this run we'll be the ones to stay at the top due to our futuristic thinking. | ammirator |
1,891,078 | Associations in EF Core | let's dive into a comprehensive guide on associations in Entity Framework Core (EF Core). ... | 0 | 2024-06-17T10:28:09 | https://dev.to/muhammad_salem/associations-in-ef-core-14d3 | dotnet, efcore | let's dive into a comprehensive guide on associations in Entity Framework Core (EF Core).
### Associations in Entity Framework Core
In object-oriented programming and database design, associations represent relationships between entities. EF Core supports several types of associations:
1. **One-to-One (1:1)**
2. **One-to-Many (1:N)**
3. **Many-to-Many (M:N)**
Each type of association is handled differently in EF Core. Here’s a detailed guide on how to define and work with these associations.
#### 1. One-to-One (1:1)
In a one-to-one relationship, each entity instance is related to a single instance of another entity.
**Example:** A `User` has one `Profile`.
**Defining One-to-One Relationship:**
```csharp
public class User
{
public int UserId { get; set; }
public string Name { get; set; }
public Profile Profile { get; set; }
}
public class Profile
{
public int ProfileId { get; set; }
public string Bio { get; set; }
public int UserId { get; set; }
public User User { get; set; }
}
public class ApplicationDbContext : DbContext
{
public DbSet<User> Users { get; set; }
public DbSet<Profile> Profiles { get; set; }
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<User>()
.HasOne(u => u.Profile)
.WithOne(p => p.User)
.HasForeignKey<Profile>(p => p.UserId);
}
}
```
### 2. One-to-Many (1:N)
In a one-to-many relationship, each entity instance in one entity is related to multiple instances of another entity.
**Example:** An `Instructor` can teach multiple `Course` instances.
**Defining One-to-Many Relationship:**
```csharp
public class Instructor
{
public int InstructorId { get; set; }
public string Name { get; set; }
public ICollection<Course> Courses { get; set; }
}
public class Course
{
public int CourseId { get; set; }
public string Title { get; set; }
public int InstructorId { get; set; }
public Instructor Instructor { get; set; }
}
public class ApplicationDbContext : DbContext
{
public DbSet<Instructor> Instructors { get; set; }
public DbSet<Course> Courses { get; set; }
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<Instructor>()
.HasMany(i => i.Courses)
.WithOne(c => c.Instructor)
.HasForeignKey(c => c.InstructorId);
}
}
```
### 3. Many-to-Many (M:N)
In a many-to-many relationship, each entity instance is related to many instances of another entity, and vice versa.
**Example:** Students can enroll in multiple courses, and each course can have multiple students.
**Defining Many-to-Many Relationship:**
Before EF Core 5.0, you needed a join entity. From EF Core 5.0 onwards, you can directly define many-to-many relationships.
**Using a Join Entity (EF Core < 5.0):**
```csharp
public class Student
{
public int StudentId { get; set; }
public string Name { get; set; }
public ICollection<StudentCourse> StudentCourses { get; set; }
}
public class Course
{
public int CourseId { get; set; }
public string Title { get; set; }
public ICollection<StudentCourse> StudentCourses { get; set; }
}
public class StudentCourse
{
public int StudentId { get; set; }
public Student Student { get; set; }
public int CourseId { get; set; }
public Course Course { get; set; }
}
public class ApplicationDbContext : DbContext
{
public DbSet<Student> Students { get; set; }
public DbSet<Course> Courses { get; set; }
public DbSet<StudentCourse> StudentCourses { get; set; }
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<StudentCourse>()
.HasKey(sc => new { sc.StudentId, sc.CourseId });
modelBuilder.Entity<StudentCourse>()
.HasOne(sc => sc.Student)
.WithMany(s => s.StudentCourses)
.HasForeignKey(sc => sc.StudentId);
modelBuilder.Entity<StudentCourse>()
.HasOne(sc => sc.Course)
.WithMany(c => c.StudentCourses)
.HasForeignKey(sc => sc.CourseId);
}
}
```
**Directly (EF Core 5.0+):**
```csharp
public class Student
{
public int StudentId { get; set; }
public string Name { get; set; }
public ICollection<Course> Courses { get; set; }
}
public class Course
{
public int CourseId { get; set; }
public string Title { get; set; }
public ICollection<Student> Students { get; set; }
}
public class ApplicationDbContext : DbContext
{
public DbSet<Student> Students { get; set; }
public DbSet<Course> Courses { get; set; }
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<Student>()
.HasMany(s => s.Courses)
.WithMany(c => c.Students)
.UsingEntity<Dictionary<string, object>>(
"StudentCourse",
j => j.HasOne<Course>().WithMany().HasForeignKey("CourseId"),
j => j.HasOne<Student>().WithMany().HasForeignKey("StudentId"));
}
}
```
### Additional Considerations
1. **Navigation Properties:**
- Always define navigation properties to allow EF Core to navigate between related entities.
2. **Foreign Keys:**
- Define foreign keys explicitly to ensure the integrity of the relationships.
3. **Fluent API vs Data Annotations:**
- Use the Fluent API (`OnModelCreating`) for complex configurations. Data annotations can be used for simpler configurations directly in the entity classes.
4. **Loading Related Data:**
- Use methods like `Include` and `ThenInclude` to load related data eagerly.
```csharp
var courseWithStudents = context.Courses
.Include(c => c.Students)
.ToList();
```
5. **Cascade Delete:**
- Configure cascade delete behavior to ensure that related data is deleted as expected.
```csharp
modelBuilder.Entity<Course>()
.HasMany(c => c.Students)
.WithMany(s => s.Courses)
.OnDelete(DeleteBehavior.Cascade);
```
### Example Queries
#### Adding Data
```csharp
using (var context = new ApplicationDbContext())
{
var instructor = new Instructor { Name = "John Doe" };
var course = new Course { Title = "C# Basics", Description = "Learn the basics of C#", Instructor = instructor };
var lesson = new Lesson { Title = "Introduction to C#", Content = "Content of the lesson", Duration = 1.5, Course = course };
context.Instructors.Add(instructor);
context.Courses.Add(course);
context.Lessons.Add(lesson);
context.SaveChanges();
}
```
#### Querying Data
```csharp
using (var context = new ApplicationDbContext())
{
var courses = context.Courses
.Include(c => c.Lessons)
.ToList();
var students = context.Students
.Include(s => s.Enrollments)
.ThenInclude(e => e.Course)
.ToList();
}
```
### Summary
Associations are fundamental in modeling relationships between entities in EF Core. Understanding how to properly configure one-to-one, one-to-many, and many-to-many relationships is crucial for creating a robust and efficient data model. Using a combination of navigation properties, foreign keys, the Fluent API, and eager loading will help you manage these associations effectively. Keep practicing with different scenarios to deepen your understanding of EF Core associations! | muhammad_salem |

1,891,111 | The Right Way to Clone Nested Object/Array (Deep Clone) in Javascript | This post was originally published at... | 0 | 2024-06-17T11:18:00 | https://devaradise.com/deep-clone-nested-object-array-in-javascript/ | javascript, webdev, beginners, frontend | This post was originally published at [https://devaradise.com/deep-clone-nested-object-array-in-javascript](https://devaradise.com/deep-clone-nested-object-array-in-javascript)
As you might know, Javascript uses pass-by-reference when passing an object, array, or function to a new variable. When you pass an object, array, or function to a new variable, a reference (memory address) to the object is passed.
Any modification to the object's properties in the new variable will be reflected in the original object since they both point to the same memory location.
```javascript
const original = { name: 'Alice' };
const newVariable = original;
newVariable.name = 'Bob';
console.log(original); // { name: 'Bob' };
```
To solve this issue we can use `Object.assign()` or `{...}` spread operator to clone the original object.
```javascript
const original = { name: 'Alice' };
const newVariable = Object.assign({}, original);
newVariable.name = 'Bob';
console.log(original); // { name: 'Alice' };
```
However, this solution only works for a simple object or flat array. Meanwhile, in real-world use cases, we often have to deal with complex, nested objects and arrays.
## Object.assign and Spread Operator Are not Enough!
Recently, I encountered a bug in my project codebase that happened because the previous developer used the spread operator (`{...}`) to clone a nested object. The object structure is like this.
```javascript
const initialForm = { name: 'Alice', items: [{ value: 1 }] };
const editableForm = { ...initialForm };
```
The expected outcome from the codes is we want to have 2 objects, where the `initialForm` is the previous data before editing, and `editableForm` is the object that will be bound to a form component where the user can modify it.
If a user clicks a submit button in the form, we want to compare both objects to see if the user makes any changes. It works as expected when the user changes the name, because well they are 2 different objects.
But when we added an item or changed the item value without changing the name, the comparison didn't detect any change.
```javascript
const editableForm = { ...initialForm };
editableForm.item.push({ value: 2 });
console.log(JSON.stringify(editableForm) === JSON.stringify(initialForm)); // true
console.log(initialForm); // { name: 'Alice', items: [{ value: 1 }, { value: 2 }] }
```
It turns out that the `{ ...initialForm }` didn't clone the `items` array value to `editableForm`. The objects `initialForm` and `editableForm` are indeed 2 different objects, but they refer to the same `items` array value in memory.
To fix this issue, we browsed the internet and found some methods to clone nested objects/arrays properly.
## Modern Ways to Clone Nested Objects/Arrays
Here are some effective methods for deep cloning in modern JavaScript:
### 1. Using the new `structuredClone` function.
`structuredClone` is the newest and most recommended approach. It's built into modern browsers and offers several advantages:
- **Deep Cloning**: Handles nested structures effectively.
- **Circular References**: Can handle circular references within the object.
- **Data Type Support**: Supports data types like Dates, Sets, Maps, and more.
More details about `structuredClone` can be found in [MDN documentation](https://developer.mozilla.org/en-US/docs/Web/API/structuredClone#description)
#### Props
- Modern, robust, efficient, handles complex data types and circular references.
#### Cons
- Limited browser support (might require a polyfill for older browsers).
- No support for an object with function and will return a `DataCloneError`.
#### Examples
```javascript
const original = { name: 'Alice', data: [{ value: 3 }] };
const cloned = structuredClone(original);
cloned.data[0].value = 2;
console.log(original); // { name: 'Alice', data: [{ value: 3 }] }
console.log(cloned); // { name: 'Alice', data: [{ value: 2 }] }
const objWithFunction = { name: 'Alice', action: () => {} };
const objWithFunctionClone = structuredClone(objWithFunction);
// DataCloneError: Failed to execute 'structuredClone' on 'Window': () => {} could not be cloned.
```
### 2. Using JSON Serialization (`JSON.stringify` & `JSON.parse`)
This method leverages JSON conversion. It converts the object to a JSON string and then parses it back into a JavaScript object. While effective, it has limitations:
#### Pros:
- Simple and widely supported approach.
#### Cons:
- Loss of Information: Certain data types like Dates, Functions, Set, Map, and custom objects might lose their original properties during conversion.
- Circular References: Cannot handle circular references by default.
#### Example
```javascript
const original = {
name: 'Alice',
date: new Date()
};
const cloned = JSON.parse(JSON.stringify(original));
console.log(original); // {"name":"Alice", "date": Sat Jun 15 2024 12:38:56 GMT+0700 (Western Indonesia Time) }
console.log(cloned); // {"name":"Alice", "date": "2024-06-15T05:37:06.172Z" }
original.circular = original;
const circularObj = JSON.parse(JSON.stringify(original));
// TypeError: Converting circular structure to JSON
```
### 3. Using loash `cloneDeep` (Library Approach)
If you're using the lodash library, you can leverage its [`cloneDeep`](https://lodash.com/docs/4.17.15#cloneDeep) function for deep cloning. It offers similar functionality to `structuredClone` but requires an additional library.
#### Pros
- Convenient if you're already using lodash, offers deep cloning functionality.
- Widely supported
#### Cons:
- Introduces an external dependency.
#### Examples
```javascript
import { cloneDeep } from 'lodash';
const original = { name: 'Alice', data: [{ value: 3 }] };
const cloned = cloneDeep(original);
cloned.data[0].value = 2;
console.log(original); // { name: 'Alice', data: [{ value: 3 }] }
console.log(cloned); // { name: 'Alice', data: [{ value: 2 }] }
```
### 4. Manual Deep Clone (Recursive Approach)
For more control and handling of specific data types, you can write a recursive function to traverse the object structure and create new copies at each level. This approach offers flexibility but requires more coding effort.
## Choosing the Right Method
The best method for deep cloning depends on your specific needs and browser compatibility. Here's a quick guide:
- Use `structuredClone` for the most modern and robust solution, or when working in Nodejs environment
- Use JSON serialization for a simpler approach, but be aware of limitations.
- Use `lodash.cloneDeep` if you're already using lodash.
- Use a manual recursive approach for fine-grained control or handling specific data types.
## Conclusion
By understanding these different methods for deep cloning nested objects and arrays in JavaScript, you can ensure your code works as intended and avoid unintended modifications to the original data. Choose the method that best suits your project requirements and browser compatibility.

## Problem description
When drawing a pie chart for the first time, I hope to highlight a block. How should I configure it?
## Solution
1. First, you need to set the graphic style in the selected state in the chart spec configuration.
```
pie: {
state: {
selected: {
outerRadius: 0.85,
stroke: '#000',
lineWidth: 1
}
}
},
```
2. Set the default selected data item through setSelected API
```
const vchart = new VChart(spec, { dom });
vchart.renderSync();
vchart.setSelected({
// one data record
})
```
## Code example
```
const spec = {
type: 'pie',
data: [
{
id: 'id0',
values: [
{ type: 'oxygen', value: '46.60' },
{ type: 'silicon', value: '27.72' },
{ type: 'aluminum', value: '8.13' },
{ type: 'iron', value: '5' },
{ type: 'calcium', value: '3.63' },
{ type: 'sodium', value: '2.83' },
{ type: 'potassium', value: '2.59' },
{ type: 'others', value: '3.5' }
]
}
],
outerRadius: 0.8,
innerRadius: 0.5,
padAngle: 0.6,
valueField: 'value',
categoryField: 'type',
pie: {
state: {
selected: {
outerRadius: 0.85,
stroke: '#000',
lineWidth: 1
}
}
},
};
const vchart = new VChart(spec, { dom: CONTAINER_ID });
vchart.renderSync();
vchart.setSelected({ type: 'oxygen'})
// Just for the convenience of console debugging, DO NOT COPY!
window['vchart'] = vchart;
```

1,890,494 | Write Less, Fix Never: The Art of Highly Reliable Code | If you're a developer tirelessly pushing out new changes, only to be dragged back by errors in your... | 0 | 2024-06-17T11:14:20 | https://dev.to/middleware/write-less-fix-never-the-art-of-highly-reliable-code-5a0i | developer, productivity, programming, career | 
If you're a developer tirelessly pushing out new changes, only to be dragged back by errors in your past work, this post is incredibly relevant for you.
Over the past decade in software development, one of the key mistakes I've made and seen others make repeatedly — is focusing on doing more work rather than ensuring the work done (no matter how small) is robust and will continue to work properly. These recurring errors can significantly hamper productivity and motivation.
From my own share of mistakes, I’ve learned valuable lessons. Here, I’d like to share a few strategies that will not only help you **ship robust software** but also **free you from the shackles of your past work**.
We will talk about the top 5 strategies that worked for me:
1. [Plan for 10x](#1-plan-for-10x)
2. [Psst: Your old work got a bug and is calling you back](#2-psst-your-old-work-got-a-bug-and-is-calling-you-back)
3. [Make the Systems Work for You, Not the Other Way Around](#3-make-the-systems-work-for-you-not-the-other-way-around)
4. [Always Answer with a Link](#4-always-answer-with-a-link)
5. [Understand software building is a team sport](#5-understand-software-building-is-a-team-sport).
## 1. Plan for 10x
There are two types of engineers IMHO: those who hack their way through for today and those who design for the distant future. Neither approach is sustainable on its own.
Your code should be able to handle the growth your business is about to experience. However, over-designing for future challenges can lead to unnecessary complexity. There's a term dedicated to this - [Bike Shedding](https://thedecisionlab.com/biases/bikeshedding)
Here's my practical rule of thumb: plan for 10 times the current scale or consider how much your business is expected to grow in the next 2-3 years. Ensure your plans align with your business goals.
For example, if you're a cab company designing a booking module, and today your company handles 10,000 rides a day with an expectation to reach 100,000 rides a day in 2 years, use that as your benchmark. Designing a system for 10 million rides a day when you're only doing 10,000 rides might result in an overly complex and expensive solution.
## 2. Psst: Your old work got a bug and is calling you back
"Days and weeks of debugging can save you a few hours of writing tests" - someone wise.
Shipping code without testing all the edge cases is like a spray and pray strategy. The simplest way to ensure your code works as expected is by adding unit tests. This might sound obvious, but the importance of thorough testing cannot be overstated.
Unit tests not only act as the first line of defense against obvious errors but also serve as insurance for your code against unintended changes that could violate business requirements. Hence, reducing those adhoc bugs being assigned to you every sprint 😉
**A trick for the lazy (like me)**: Before you write the code:
- Write tests covering every corner case you can think of.
- Pretend you're trying to break someone else's system.
- Write assert False in all the tests and run them.
- Naturally, all tests will fail.
Now, just work towards making each test pass. This approach takes less time overall and produces robust code every time!
## 3. Make the Systems Work for You, Not the Other Way Around
One of my managers once gave me the most impactful advice: "Act, don't react." This advice came when I was constantly being tagged on different Slack channels for problems, customer complaints, and payment failures. I was just reacting to each request, having no clue what might happen next.
That's when I started asking three questions for every feature I built:
- How will I know it's working?
- How will I know it failed?
- How will I know it succeeded?
I then answered these questions at every level (feature, screens, app) by sending metrics to our APM tools like Datadog or NewRelic.
After setting this up, I configured alerts to notify me if anything went wrong.
By doing this, I became aware of bugs before they escalated into major issues, preventing reactive measures, poor customer experiences, and my own uncertainty about what might come next.
Start answering these three fundamental questions every time you build something to ensure you always act instead of react.
## 4. Always Answer with a Link
Just like bad work gets you tagged on various Slack channels for fixes, great work gets you tagged for context in areas you've worked on.
This can drain your energy when you least expect it, or worse, it can make you the go-to person for the same tasks because you know the complete picture.
**Keep this secret trick to yourself:**
Document everything. Include the context, architecture, and business-specific decisions you made while building the feature. When someone asks about the context of an area (feature, screen, app), just send them the link to the updated document. This will save you a few hours every time.
Additionally, thorough documentation makes onboarding new team members easier and ensures that your work remains accessible and understandable over time.
## 5. Understand software building is a team sport.
Software engineering often emphasizes the individual contributor path. However, reaching the end goal alone is impossible—you only reach it with your team (and vice versa).
Understanding and adopting a process excellence mindset helps you leverage the team's collective productivity.
Sorry for that worded statement 😄
To simplify, ensuring that reviews, deployments, and any collaborative activities involving code don't have significant wait times boosts your productivity immensely!
The best way to identify high waiting or blocked times in your team is to measure DORA metrics. You can use an open-source tool like [Middleware](https://github.com/middlewarehq/middleware), which provides [DORA metrics](https://www.middlewarehq.com/blog/what-are-dora-metrics-how-they-can-help-your-software-delivery-process) out of the box.
{% embed https://github.com/middlewarehq/middleware %}
PS: I'm also co-founder of [Middleware](https://middlewarehq.com) and our mission is to make engineering frictionless for engineers. Do consider giving us a star if you like what we've built!
## Ship code like a boss!
By adopting these suggestions, you can significantly reduce the time spent revisiting and fixing past work. This will not only enhance your productivity but also ensure that your focus remains on innovating and delivering new features.
Be productive, not busy! All the best 😊 | dhruvagarwal |

Managing a company's workforce is a crucial aspect of any business operation. To ensure smooth and efficient management of employees, many organi- zations rely on powerful software called Human Capital Management (HCM) systems. One such system that stands out is Workday Human Capital Management. This comprehensive guide will delve into the details of how Workday HCM functions, the importance of testing for its seamless functioning, and the advantages of using test automation.
**Understanding Workday Human Capital Management**
Workday Human Capital Management is a cloud-based system that can handle different human resources tasks. It helps with recruiting new employees, managing payroll, and developing talent within the organization. This system offers a customizable framework, allowing companies to tailor it to their specific needs. By using Workday HCM, businesses can improve collaboration among teams, align their workforce with strategic goals, and simplify complex HR procedures.
Workday releases updates biannually to ensure its users have access to the latest features and functionality across both web browsers and mobile devices. This continuous improvement approach keeps Workday's offerings at the forefront of innovation, empowering businesses to streamline their operations and stay competitive in an ever-evolving digital landscape.
**Modules of Workday Human Capital Management**
Workday's comprehensive Human Capital Management (HCM) module is a powerful tool that simplifies workforce management and HR activities. Some distinct features offered by the tool are:

**Time Tracking**: Interacting with payroll, project management, and task management for simplified time tracking.
**Importance of Testing in Workday HCM**
Thoroughly examining the Workday Human Capital Management system before deployment and during its ongoing operation is extremely vital. Overlooking rigorous testing exposes companies to a multitude of risks, including technical disruptions that could bring operations to halt, data inaccuracies that undermine decision-making, reduced user adoption due to frustration with performance issues, financial losses stemming from downtime or reputational damage, and long-term harm to the organization's credibility and public image.
**Impact of Workday Testing on ROI**
For enterprises transitioning from legacy systems to the cutting-edge Workday platform, prioritizing testing from the outset is imperative to optimizing their return on this significant investment (ROI). Delaying testing until the final stages of the deployment process can lead to costly setbacks, including delays in going live and escalating expenses associated with rectifying defects discovered late in the game. However, by proactively shifting testing timelines and implementing automated testing solutions early on, organizations can dramatically reduce the overall testing workload, accelerate deployments, and hasten the realization of favorable ROI. Innovative test automation tools, such as the powerful Opkey platform, offer cost-efficient solutions tailored to streamlining complex Workday testing processes.
**Choosing the Right Workday HCM Test Automation Tool**
When companies need to test their Workday system, they should choose a tool that is affordable, easy to use, and has lots of helpful features. Opkey is a great choice because it has pre-built tools that make testing faster, allows users to create automated tests without coding, can automatically fix broken test scripts, and can test the entire Workday system from start to finish. These amazing features help companies test their Workday Human Capital Management system more quickly, spend less time fixing broken scripts, and get more value from their investment in Workday.
**Automating Workday HCM Testing for Enhanced HR Processes**
Testing Workday HCM systems manually is really hard. Writing test scripts takes a long time. Running the tests manually is slow and boring. Getting the test data ready is complicated too. But automating Workday testing makes everything much easier, faster, and more accurate. Automated tests can check more of the system to make sure it works right and follows all the rules. Automating testing saves money, lets companies get feedback and make improvements to their Workday system more quickly. Opkey's no-code approach is awesome because anyone can create and run robust test suites, even if they don't know how to code. This ensures the Workday system is working at its best and running efficiently.
**Concluding Remarks**!
Workday Human Capital Management is a strong tool that helps businesses manage their HR processes better. It makes things more organized and helps companies succeed. Testing and using tools like Opkey for automation are very important. They help make sure that when new parts of Workday are added, everything works smoothly. Testing and automation also help Workday run better and faster. This lets companies get more value from their investment in Workday. As the digital world keeps changing, testing and automation are becoming more and more crucial. | rohitbhandari102 |

## Exploring the World of Face Swap through Deepfake Technology
The world of face swap is driven by deepfake technology, revolutionizing the way we interact with adult content.
### What is a Face Swap?
Face swap is a technique that involves swapping the faces of two individuals in an image or video. In the context of AI and deepfake technology, face swap allows for the realistic manipulation of facial features for various purposes.
### How Does AI Face Swap Technology Work?
Using advanced algorithms involving deep learning and neural networks, AI face swap technology analyzes facial features in images or videos and replaces them with others seamlessly. By mapping key points on faces, the tool swaps expressions, movements, and features to create realistic face swaps.
### Deepfake Technology in the Adult Content Industry
The development of deepfake technology has significantly impacted the adult content industry, allowing people now to easily generate deepfake content by swapping faces in videos. As deepfake technology continues to improve, it poses significant concerns regarding privacy, and ethics, especially stricter regulations in the adult entertainment industry. At the same time, AI advancements may help in identifying and stopping the spread of deepfake content.

1,891,098 | How to Use Ollama for Front-end with Streaming Output | Introduction LLM applications are becoming increasingly popular. However, there are... | 27,713 | 2024-06-17T10:58:52 | https://medium.com/@ppaanngggg/how-to-use-ollama-for-front-end-with-streaming-output-30052f7bf8fc | webdev, ollama, llm, nextjs | ## Introduction
LLM applications are becoming increasingly popular. However, there are numerous LLM models, each with its differences. Handling streaming output can be complex, especially for new front-end developers.
Thanks to the [AI SDK](https://sdk.vercel.ai/) developed by Vercel, implementing LLM chat in next.js with streaming output has become incredibly easy. Next, I'll provide a step-by-step tutorial on how to integrate Ollama into your front-end project.
## Install Ollama
Ollama is the premier local LLM inferencer. It allows for direct model downloading and exports APIs for backend use. If you're seeking lower latency or improved privacy through local LLM deployment, Ollama is an excellent choice. For installation, if you're using Linux, simply run the following command:
```bash
curl -fsSL https://ollama.com/install.sh | sh
```
If you're using a different OS, please follow this [link](https://ollama.com/download).
## Create a New Next.js Project
To create a new Next.js project, enter the command `npx create-next-app@latest your-new-project`. Make sure you choose App route mode. After that, run `npm dev` and open `localhost:3000` in your preferred browser to verify if the new project is set up correctly.
Next, you need to install the AI SDK:
```bash
npm install ai
```
The AI SDK utilizes a sophisticated provider design, enabling you to implement your own LLM provider. At present, it is only necessary to install the Ollama provider offered by third-party support.
```bash
npm install ollama-ai-provider
```
## Server-Side Code
Now that you've gathered all the prerequisites for your LLM application, create a new file named `actions.ts` in the `app` folder:
```tsx
"use server";
import { ollama } from "ollama-ai-provider";
import { streamText } from "ai";
import { createStreamableValue } from "ai/rsc";
export interface Message {
role: "user" | "assistant";
content: string;
}
export async function continueConversation(history: Message[]) {
"use server";
const stream = createStreamableValue();
const model = ollama("llama3:8b");
(async () => {
const { textStream } = await streamText({
model: model,
messages: history,
});
for await (const text of textStream) {
stream.update(text);
}
stream.done();
})().then(() => {});
return {
messages: history,
newMessage: stream.value,
};
}
```
Let me provide some explanation about this code.
1. `interface Message` is a shared interface that establishes the structure of a message. It includes two properties: 'role' (which can be either 'user' or 'assistant') and 'content' (the actual text of the message).
2. The `continueConversation` function is a server component that utilizes the conversation history to generate the assistant's response. This function interacts with the Ollama model (specifically `llama3:8b`, but you can replace it with any model of your choice) to generate a continuous text output.
3. The `streamText` function is part of the AI SDK and it creates a text stream that will be updated with the assistant's response as it is generated.
## Client-Side Code
Next, replace the contents of `page.tsx` with the new code:
```tsx
"use client";
import { useState } from "react";
import { continueConversation, Message } from "./actions";
import { readStreamableValue } from "ai/rsc";
export default function Home() {
const [conversation, setConversation] = useState<Message[]>([]);
const [input, setInput] = useState<string>("");
return (
<div>
<div>
{conversation.map((message, index) => (
<div key={index}>
{message.role}: {message.content}
</div>
))}
</div>
<div>
<input
type="text"
value={input}
onChange={(event) => {
setInput(event.target.value);
}}
/>
<button
onClick={async () => {
const { messages, newMessage } = await continueConversation([
...conversation,
{ role: "user", content: input },
]);
let textContent = "";
for await (const delta of readStreamableValue(newMessage)) {
textContent = `${textContent}${delta}`;
setConversation([
...messages,
{ role: "assistant", content: textContent },
]);
}
}}
>
Send Message
</button>
</div>
</div>
);
}
```
This is a very simple UI you can continue talk with LLM model now. There are some important snips:
1. The `input` field captures the user's input. It is controlled by a React state variable that gets updated every time the input changes.
2. The `button` has an `onClick` event that triggers the `continueConversation` function. This function takes the current conversation history, appends the user's new message, and waits for the assistant's response.
3. The `conversation` array holds the history of the conversation. Each message is displayed on the screen, and new messages are appended at the end. By using `readStreamableValue` from the AI SDK, we're able to read the streaming output value from the server component function and update the conversation in real-time.
## Let’s Test Now
I type "who are you" into the input placeholder.
Here is the output of `llama:8b` supported by Ollama. You'll notice that the output is printed in a streaming manner.

In... | 0 | 2024-06-17T10:51:42 | https://dev.to/dynamicmethods/a-detailed-guide-to-web-application-development-in-2024-1iji | html, angular, javascript | **[Web application development](https://dynamic-methods.com/web-application-development-services/)** is a symbol of the constant change that defines the modern world. In 2024, there will be more users than ever before. In addition to practicality, consumers expect outstanding, engaging, and inventive experiences.
This guide shows you how to become a smart web app developer, using the latest technologies, digital advancements, and tried-and-tested code lines to build web apps that thrive in this dynamic environment.
## Technologies Used in Web Application Development
It is essential to focus on the basics first instead of directly jumping into frameworks, language, and integrating AI. It may be true that there are emerging innovations that mark a new era in web development, but still, the three major technologies that form the foundation of web development are HTML, CSS, and JavaScript.
- **HTML (HyperText Markup Language):** The building block to the structure of your web app is HTML – this is what defines your content and the structure of your pages. rehearse mastery of primary HTML components, characteristics, and marking tags for reliable structure.
- **CSS (Cascading Style Sheets):** Creating a stunning and engaging User Interface, CSS determines the appearance of your web application. Learning CSS properties such as Flexbox Grid Layout, media queries, and many others helps you in achieving the desired responsive design whereby the app adjusts accordingly depending on the type of device being used.
- **JavaScript:** A language for making your web applications interactive. In 2024, the emphasis on knowing the variables, functions, DOM manipulation, and event handling of JavaScript will be critical. Phinze takes a deep dive into core JavaScript concepts such as modules, arrow functions, and the spread operator to maintain clean and efficient code.
## Web Application Development Frameworks
## Frontend Frameworks
Frontend frameworks provide the essential elements and features that allow developers to start building web applications and speed up the process by reducing the time spent learning foundational languages.
Here are some of the most popular choices in 2024:
- **React:** Another popular framework developed by Facebook, React is a library that helps in creating interactive and reusable components. React native has a virtual DOM that helps ensure an efficient rendering process for scaling up web apps.
- **Angular:** One such recipe-based organized approach is provided by Google's angular which comes with features such as dependency injection and routing. It is suitable for business-level, mission-critical implementations.
- **Vuejs:** Vue.js is a library that is known for its lightweight and quick learning abilities. offers a high level of polymorphism and dynamic nature. It is good for simpler projects or if you prefer a relatively light and easy framework to learn.
- **Svelte:** Svelte is a young and progressive framework that translates all code into optimized vanilla JavaScript at the build stage. This leads to extremely quick and lightweight web applications.
## Backend Frameworks
The backend foundation is a critical component that keeps your web application running smoothly, even though the front end is where users interact with its magic.
Here are some key backend technologies to consider:
- **Node. js:** Another great framework for creating real-time applications – Node. js is a JavaScript runtime environment that provides run-time environments for the JavaScript programming language on the server side. It is also event-driven and is designed for I/O intensive applications and hence is highly suitable for real-time applications.
- **Python:** Python is a dynamic and object-oriented multipurpose language suitable for beginners and widely spread on the web because of the large number of libraries and frameworks such as Django and Flask. It is a structured language with a clear syntax and ease of use, which makes it ideal for the development of both the backend and big data in an organization.
- **Java:** Java is a complicated and developed language that is used mainly for building applications at the business level. It is primarily aimed at achieving maximum security and scalability for websites with high traffic volumes.

Throughout your container journey, you will be pulling, starting, stopping, and removing containers from your local environment quite frequently. Prior to deploying a container in a production environment, it is critical to run the container locally to understand how it should work. This includes starting, stopping and restarting containers, getting details about how the container is running, and, of course accessing verbose logs to view critical details about the applications running inside the container. The basic commands we are going to discuss are the following:
- **docker start**: This command starts a container instance that is no longer in a running state.
- **docker stop**: This command stops a running container instance.
- **docker restart**: This command restarts a running container.
- **docker pull**: This command downloads a container image to the local cache.
- **docker attach**: This command allows users to gain access (or attach) to the primary process of a running Docker container instance.
- **docker exec**: This command executes a command inside a running container.
- **docker rm**: This command deletes a stopped container.
- **docker rmi**: This command deletes a container image.
- **docker inspect**: This command shows verbose details about the state of a container.
Container life cycle management is an essential component of managing containers in production environments. Knowing how to investigate running containers is a critical skill that will help you evaluate the health of your containerized infrastructure.
In the following exercise, we are going to manage a container using these commands.
### Managing Container Life Cycles
When managing containers in any kind of environment, it is important to understand the status of container instances. Most of the time we use base container images that contain a specific baseline configuration on top of which the applications are deployed. Ubuntu is one of the most commonly used base images that are used for packaging applications.
Unlike a full operating system image, the Ubuntu base container image is quite slim and intentionally leaves out a lot of packages. Most of the base images do have a package system that allows us to install any missing package.
Keep in mind, though, that you want to keep the base images as slim as possible, only installing the packages you really need. This ensures that container images can quickly be pulled and started by Docker hosts.
In this exercise, we will work with the official Ubuntu base container image. This image will be used to start container instances on which we will use various container life cycle management commands.
In a new terminal or PowerShell window, execute the **docker pull** command to download **Ubuntu 18.04** container image. Remember, we can use tags to specify the image version. If you don't provide a tag, the latest will automatically be pulled.
```powershell
docker pull ubuntu:18.04
```
You should see the following output:
```
18.04: Pulling from library/ubuntu
7c457f213c76: Pull complete
Digest: sha256:152dc042452c496007f07ca9127571cb9c29697f42acbfad72324b2bb2e43c98
Status: Downloaded newer image for ubuntu:18.04
docker.io/library/ubuntu:18.04
```
---
Use the **docker pull** command to download the **Ubuntu 19.04** base image:
```powershell
docker pull ubuntu:19.04
```
You should see the following output:
```
19.04: Pulling from library/ubuntu
4dc9c2fff018: Pull complete
0a4ccbb24215: Pull complete
c0f243bc6706: Pull complete
5ff1eaecba77: Pull complete
Digest: sha256:2adeae829bf27a3399a0e7db8ae38d5adb89bcaf1bbef378240bc0e6724e8344
Status: Downloaded newer image for ubuntu:19.04
docker.io/library/ubuntu:19.04
```
---
Use the **docker images** command to confirm that the container images are downloaded to the local container cache:
```powershell
docker images
```
The contents of the local container cache will display the **Ubuntu 18.04** and **Ubuntu 19.04** base images, as well as any other images you have in your local cache:
```
REPOSITORY TAG IMAGE ID CREATED SIZE
ubuntu 18.04 f9a80a55f492 12 months ago 63.2MB
hello-world latest d2c94e258dcb 13 months ago 13.3kB
ubuntu 19.04 c88ac1f841b7 4 years ago 70MB
... ... ... ... ...
```
---
Before running these images, use the **docker inspect** command to get verbose output about the images. In your terminal, run the **docker inspect** command and use the **IMAGE ID** value if the **Ubuntu 18.04** container image as an argument:
```powershell
docker inspect f9a80a55f492
```
The **inspect** output will contain a large list of attributes that define the container. For example, you can see what environment variables are configured within the container, whether the container has a hostname set when the image was last updated, and a breakdown of all of the layers that define that container.
```
"Id": "sha256:f9a80a55f492e823bf5d51f1bd5f87ea3eed1cb31788686aa99a2fb61a27af6a",

```
---
Inspecting the **Ubuntu 19.04** container, you can see that this parameter is different. Run the **docker inspect** command in the **Ubuntu 19.04** container image ID:
```powershell
docker inspect c88ac1f841b7
```
In the displayed output, you will see that this container image was created on a different date to the **18.04** container image:
```
"Id": "sha256:c88ac1f841b72add46f5a8b0e77c2ad6864d47e5603686ea64375acd55e27906",

```
This can be useful if, for example, you know that a security vulnerability might be present in an Ubuntu base image.
---
After inspecting both the container images, it will be clear that our best choice in this scenario is to stick with the LTS 18.04 release. The preceding outputs show that the 18.04 release is more up to date than the 19.04. This is something to be expected, as Ubuntu generally will provide more stable updates for the LTS releases.
---
Write the **docker run** command with the **-d** flag on your terminal of choice to start up an instance of the Ubuntu 18.04 container:
```powershell
docker run -d ubuntu:18.04
```
This time we are using the **-d** flag. This tells Docker to run the container in **daemon mode** (or in the background). If we omit the **-d** flag, the container will take over our current terminal session until the primary process inside the container terminates.
---
Check the status of the container using the **docker ps -a** command:
```powershell
docker ps -a
```
This will reveal a similar output to the following:
```
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
f05ee6d22795 ubuntu:18.04 "/bin/bash" 2 minutes ago Exited (0) 2 minutes ago condescending_thompson
```
The container is stopped and exited. This is because the primary process inside this Ubuntu container is **/bin/bash**, which is a shell. The Bash shell cannot run without being executed in an interactive mode since it expects text input from the user.
---
Run the **docker run** command again, passing in the **-i** flag to make the session interactive, and the **-t** flag to allocate a **pseudo-tty** handler to the container. A **pseudo-tty** handler will essentially link the user's terminal to the interactive Bash sell running inside the container.
This will allow Bash to run properly since it will instruct the container to run in an interactive mode, expecting user input. You can also give the container a human-readable name by passing in the **--name** flag. Use the following command in your terminal:
```powershell
docker run -i -t -d --name ubuntu18 ubuntu:18.04
```
You should now see the new instance running, as well as the instance that failed to start previously:
```
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
0b4b857747a5 ubuntu:18.04 "/bin/bash" 21 seconds ago Up 20 seconds ubuntu18
f05ee6d22795 ubuntu:18.04
```
---
We now have an Ubuntu container up and running. We can run commands inside the container using the **docker exec** command. We can use the **exec** command to access a Bash shell, which will allow us to run commands inside the container. Similar to **docker run**, pass in the **-i** and **-t** flags to make it an interactive session. Also pass in the name or ID of the container, so that Docker knows which container you are targeting. The final argument of **docker exec** is always the command you wish to execute. In this case, it will be **/bin/bash** to start a Bash shell inside the container instance:
```powershell
docker exec -it ubuntu18 /bin/bash
```
You should immediately see your terminal to change to a root shell. This indicates that you have successfully launched a shell inside your Ubuntu container. The hostname of the container, (in my case **0b4b857747a5**) is taken from the first twelve characters of the container ID. This allows the user to know for certain which container they are accessing
```bash
root@0b4b857747a5:/#
```
---
Run the **echo** command inside the **ubuntu18** container instance to write a hello world message:
```bash
echo "Hello world from ubuntu18" > helloworld.txt
```
---
Run the **exit** command to exit from the Bash shell of the **ubuntu18** container. You should return to your normal terminal shell:
```bash
root@0b4b857747a5:/# exit
```
---
Now, lets create a second container named **ubuntu19** that will also run in the Docker environment using the **Ubuntu 19.04** image:
```powershell
docker run -itd --name ubuntu19 ubuntu:19.04
```
---
Again, run the **docker exec** to access a shell of this second container. Remember to use the name or container ID of the new container you created. Likewise, access a Bash shell inside this container, so the final argument will be **/bin/bash**:
```powershell
docker exec -it ubuntu19 /bin/bash
```
You should see that the prompt once again changed to a Bash root shell, similar to how it did for the **Ubuntu 18.04** container image:
```bash
root@b073985d739a:/#
```
---
Run the **echo** command inside the **ubuntu19** container instance to write a hello world message:
```bash
echo "Hello world from ubuntu19" > helloworld.txt
```
---
Currently, you should have two Ubuntu container instances running in your Docker environment, with two separate **hello-world** files in the home directory. If you run the **docker ps** command, you should see your containers
```
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
b073985d739a ubuntu:19.04 "/bin/bash" 11 minutes ago Up 11 minutes ubuntu19
0b4b857747a5 ubuntu:18.04 "/bin/bash" 3 hours ago Up 3 hours ubuntu18
```
---
Instead of using **docker exec** to access a shell inside our containers, we are going to use it to display the output of the **helloworld.txt** files, by executing the **cat** command inside the containers
```powershell
docker exec -it ubuntu18 cat helloworld.txt
```
The output will display the **helloworld** message we added to the container in previous steps. Notice that as soon as the **cat** command was completed and the output displayed, the user was moved back to the context of the main terminal. This is because the **docker exec** session will only exist for as long the command provided by the user is running.
In the previous example of the Bash shell, Bash will only exit if the user terminates it by using the **exit** command. In this example, only the **Hello world** output is displayed, because the **cat** command displayed the output and exited, and thus, terminating the **docker exec** session.
```
Hello world from ubuntu 18
```
---
Run the same **cat** command in the **ubuntu2** container instance:
```
Hello world from ubuntu 19
```
As you can see, Docker was able to allocate an interactive session on both the containers, execute the command, and return the output directly in our running container instances.
---
In a similar manner to that we used to execute commands inside our running containers, we can also stop, start and restart them. Stop one of your container instances using the **docker stop** command. In your terminal session, execute the **docker stop** command, followed by the name or container ID of the **ubuntu19** container:
```powershell
docker stop ubuntu19
```
This command should return the name of the container.
---
We can use the **docker ps** command to view all running container instances:
```powershell
docker ps
```
The output will display the **ubuntu1** container up and running:
```
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
c8c0010f65fb ubuntu:18.04 "/bin/bash" 5 days ago Up 4 seconds ubuntu18
```
---
Execute the **docker ps -a** command to view all container instances, regardless of whether they are running. This will show us the stopped container:
```powershell
docker ps -a
```
The output should display something similar to the following:
```
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
df6354e844f9 ubuntu:19.04 "/bin/bash" 5 days ago Exited (0) 5 days ago ubuntu19
c8c0010f65fb ubuntu:18.04 "/bin/bash" 5 days ago Up 2 minutes ubuntu18
```
From this state we can experiment with starting, stopping, or executing commands inside the containers.
---
When container instances are in a stopped state, we can use the **docker rm** command to delete the container instances altogether. Use the **docker rm** followed by the name or id of the container to delete the **ubuntu19** instance:
```powershell
docker rm ubuntu19
```
The output should be the name of the container
---
To completely reset the state of your docker environment, delete the base images you downloaded during this post. Use the **docker images** command to view the cached based images:
```powershell
docker images
```
A list of Docker images and associated metadata in the local cache should be displayed:
```
REPOSITORY TAG IMAGE ID CREATED SIZE
ubuntu 18.04 f9a80a55f492 12 months ago 63.2MB
hello-world latest d2c94e258dcb 13 months ago 13.3kB
ubuntu 19.04 c88ac1f841b7 4 years ago 70MB
```
---
Use the **docker rmi** command followed by an image ID to delete the first image:
```powershell
docker rmi f9a80a55f492
```
Similar to **docker pull**, the **rmi** command will delete each image and all associated layers
```
Untagged: ubuntu:18.04
Untagged: ubuntu@sha256:152dc042452c496007f07ca9127571cb9c29697f42acbfad72324b2bb2e43c98

```
It is important to periodically clean up your Docker environment, as building and running containers can cause large amounts of disk usage over time. To streamline the cleaning up of your environment, Docker provides a **prune** command that will automatically remove old containers and base images
```powershell
docker system prune -fa
```
Executing this command will remove any container images that are not tied to an existing running container, along with any other resources in your Docker environment.
## Summary
Using commands such as `docker run`, `docker start`, `docker exec`,
`docker ps`, and `docker stop`, we have explored the basics of container life cycle management through the Docker CLI. Through the various steps in this post, we launched container instances from the same base image, configured them using `docker exec`, and cleaned up the deployments using other basic container life cycle commands such as `docker rm` and `docker rmi`.

If you’re looking to build dApps or interact with the Solana ecosystem, running your own RPC node offers several advantages:
**Reduced Reliance**: Free yourself from dependence on public RPC nodes, ensuring data sovereignty and potentially faster response times.
**Customization**: Tailor the node to your specific needs, enabling features like filtering or whitelisting requests.
Solana relies on validators, which are computers that maintain the network. Each validator runs a program to track accounts and validate transactions. Without validators, Solana wouldn’t function.
Before diving into RPC, let’s clarify a key distinction. The validator software offers two deployment options: voting/consensus nodes and RPC nodes. While both leverage the same software, RPC nodes prioritize performance and refrain from voting. Unlike validator nodes focused on consensus, RPC nodes serve a distinct purpose within the cluster. They act as information providers, responding to blockchain inquiries and facilitating transaction submissions from users.

1,891,080 | How AI Virtual Staging is Transforming Property Listings | Introduction In an increasingly digital world, the real estate industry is embracing... | 0 | 2024-06-17T10:50:00 | https://dev.to/novita_ai/how-ai-virtual-staging-is-transforming-property-listings-o03 | ## Introduction
In an increasingly digital world, the real estate industry is embracing innovative technologies to stay competitive and enhance property marketing. One such groundbreaking technology is AI virtual staging, which uses artificial intelligence to digitally furnish and decorate real estate photos, making them more appealing to potential buyers. At the forefront of this revolution is Virtual Staging AI, an innovative startup from the Harvard Innovation Lab. This article explores the concept of AI virtual staging, the pioneering work of Virtual Staging AI, and the transformative impact of this technology on the real estate industry.
## What is AI Virtual Staging?
AI virtual staging is a cutting-edge technology that leverages artificial intelligence to create realistic, digitally furnished and decorated images of vacant properties. Unlike traditional staging, which involves physically placing furniture and decor in a home, AI virtual staging allows real estate professionals to enhance property photos digitally. This process is not only faster and more cost-effective but also offers unparalleled flexibility in showcasing different design styles and layouts.
Traditional staging can be a time-consuming and expensive process, requiring the rental of furniture and decor, as well as the services of professional stagers. In contrast, AI virtual staging can transform empty or poorly furnished spaces into visually stunning listings within hours. By using sophisticated algorithms and image recognition technology, AI can accurately place furniture, rugs, lighting, and other decor elements in real estate photos, creating an inviting and attractive presentation that appeals to potential buyers.
## How AI Virtual Staging Works
The process of AI virtual staging involves several advanced technologies and techniques. Here's a step-by-step look at how it works:
### Image Upload
Real estate professionals upload photos of empty or sparsely furnished properties to the AI platform.
### AI Analysis
The AI system analyzes the photos, recognizing architectural features, room dimensions, and lighting conditions.
### Furniture Placement
Using a database of furniture and decor items, the AI algorithm selects appropriate pieces and places them in the photos. This includes determining the optimal placement and scaling of each item to ensure a realistic appearance.
### Rendering
The AI generates high-quality, photorealistic images that showcase the property with the newly added furnishings and decor.
### Customization
Users can make adjustments to the staging, such as changing furniture styles or color schemes, to better match their target audience's preferences.
## Difference Between AI Virtual Staging and Traditional Virtual Staging
AI virtual staging and traditional virtual staging are both methods of creating realistic images of a property without the need for physical staging. However, there are some key differences between the two methods.
AI virtual staging uses artificial intelligence to generate images of a property, while traditional virtual staging uses 3D modeling and rendering software. This means that AI virtual staging can be more affordable and faster than traditional virtual staging, but it can also be less realistic.
Here is a table comparing the two methods:
Ultimately, the best choice for you will depend on your budget, timeline, and desired level of realism.
Here are some additional things to consider when choosing between AI virtual staging and traditional virtual staging:
### The size and complexity of your property.
AI virtual staging is best suited for small to medium-sized properties with simple layouts. Traditional virtual staging is a better option for large or complex properties with multiple rooms and features.
### The desired level of customization
AI virtual staging offers less customization than traditional virtual staging. If you want to be able to choose the specific furniture, colors, and finishes used in your virtual staging, then traditional virtual staging is a better option.
#### Your timeline
AI virtual staging can be completed in a matter of days, while traditional virtual staging can take several weeks or even months. If you are on a tight deadline, then AI virtual staging is a better option.
If you are still not sure which method is right for you, I recommend talking to a real estate agent or virtual staging company. They can help you assess your needs and make the best decision for your property.

I liked this approach because it allowed to create reactive values globally in apps that are easily accessible and that could be modified when needed.
However, right now you could achieve something similar by using the composables and have a global state there. This approach is more like Vue 3 compatible with the usage of composables, script setup, and other DX utils that come natively with the framework.
In this article, I want to introduce you to the concept that I am using both in my work and hobby projects.
Enjoy!
## 🟢 Sharing composable state in Vue apps
Normally, when we create a composable, we usually do it like the following:
```ts
import { ref } from 'vue'
export const useWishlist = () => {
const wishlist = ref({})
const addToWishlist = (key, value) => {
wishlist.value[key] = value
}
return {
wishlist,
addToWishlist,
}
}
```
First, we create a new composable function
Next, we create a reactive `ref` variable that will store the state
Furthermore, we create a funtion that modifies the state.
And finally, we return all this as a part of the composable.
This approach certainly works but each call of the `useWishlist` composable will generate a new `wishlist` variable.
Sometimes, we may want to have a global reactive property that would be responsible for storing the state of the customer's wishlist. How do we do that then?
The only small different that we need to do here to achieve that is to move registration of `wishlist` variable, outside of the `useWishlist` composable like following:
```ts
import { ref } from 'vue'
const wishlist = ref({})
export const useWishlist = () => {
const addToWishlist = (key, value) => {
wishlist.value[key] = value
}
return {
wishlist,
addToWishlist,
}
}
```
This way, whenever we access the `useWishlist` composable, the value of `wishlist` will be the same globally. Thanks to this approach we can trigger `addToWishlist` method from multiple places in the application and have the `wishlist` variable being updated automatically.
If you would like to learn more about composables, check out the official docs [here](https://vuejs.org/guide/reusability/composables.html).

In the rapidly evolving landscape of artificial intelligence, the interplay between large language models ([**LLMs**](https://blogs.novita.ai/top-llms-for-2024-how-to-evaluate-and-improve-an-open-source-llm/)) and their smaller counterparts is a narrative of synergy and innovation. The towering capabilities of LLMs like GPT-3 and GPT-4, while awe-inspiring, are encased in a fortress of limitations - limited accessibility of model weights, immense computational demands, and the constraints of in-context learning (ICL).
Yet, within these confines lies a chink, an opportunity for small models to step in as plug-ins, offering a bridge to more personalized and efficient applications. This blog delves into the necessity and impact of integrating small models as plug-ins within the expansive realms of LLMs, exploring the concept of Super In-Context Learning (SuperICL) and its real-world ramifications.
## Understanding LLMs and Smaller Models
### The Differences between LLMs and Smaller Models
A Large Language Model is a sophisticated AI system designed to process and understand large volumes of natural language data. LLMs typically have a vast number of parameters, often ranging from hundreds of millions to billions. This allows them to capture intricate patterns and relationships within language, enabling advanced capabilities such as language translation, text summarization, question-answering, and content generation. LLMs are trained on large datasets and can exhibit complex behaviors and "emergent abilities" as they scale up in size, although the latter concept is subject to debate, as discussed in the Stanford research.
In contrast, smaller models have fewer parameters and are less complex. They may be more limited in their capabilities and the range of tasks they can perform effectively. Smaller models are typically used for more specific or less complex tasks due to their lower computational requirements and smaller dataset needs. While they can be very efficient and effective for certain applications, they generally do not possess the same level of nuanced understanding or the ability to handle a wide variety of language tasks as LLMs.
### What Are the Best Open-Source LLMs?
- BERT: Developed by Google, BERT is a pioneering LLM known for its transformative impact on natural language processing, utilized globally in Google Search and inspiring numerous specialized models.
- Falcon 180B: The UAE's Technology Innovation Institute's LLM with 180 billion parameters, excelling in text generation and processing, with a smaller version, Falcon-40B, also recognized for language understanding.
- GPT-NeoX and GPT-J: EleutherAI's open-source LLMs with 20 billion and 6 billion parameters, respectively, offering high performance across domains and promoting AI democratization.
- LLaMA 3: Meta AI's versatile LLM, ranging from 7 to 70 billion parameters, optimized for natural language generation and customizable through an open-source license, with APIs available for developers. Companies, e.g. [**Novita AI**](https://novita.ai/llm-api), usually offer LLaMA 3 APIs for AI startups.
- BLOOM: An open-source LLM with 176 billion parameters, a collaborative effort by Hugging Face, designed for multilingual and programming language text generation, prioritizing transparency and accessibility.
- Vicuna 13-B: Fine-tuned from LLaMa 13B, this open-source conversational model is adept at handling extended dialogues in chatbot applications across industries, showcasing advanced conversational AI capabilities.
## Why Do We Need Small Models As Plug-Ins for Large Language Models?
### Limited Accessibility of Model Weights
- LLMs like GPT-3 and GPT-4 are powerful tools for a variety of natural language processing (NLP) tasks. However, the actual weight parameters of these models are typically not shared publicly due to intellectual property and security concerns.
- Without access to the model weights, it's not possible to perform in-house fine-tuning where the model's parameters are adjusted to better suit a specific task or dataset.
### Immense Model Sizes
- LLMs are typically very large, with billions of parameters, which makes them resource-intensive. The hardware requirements for training or even fine-tuning such models are beyond the reach of most individuals and smaller organizations.
- The large size also means that transferring these models to different hardware or using them in environments with limited computational power is challenging.
### In-Context Learning (ICL) Limitations
- ICL is a technique where a few labeled examples are provided alongside the input to help the model make predictions. This method allows the model to learn from the context provided by the examples.
- However, ICL is limited by the context length that the LLM can process. If the context is too long, it may exceed the model's capacity, and the model won't be able to effectively utilize all the provided examples.
- This limitation is particularly problematic when there is a large amount of supervised data available, as ICL can only use a small subset of it due to the context length constraint.
To address these issues, some scholars propose Super In-Context Learning (SuperICL), which combines the strengths of LLMs with locally fine-tuned smaller models. The smaller models, or plug-ins, are fine-tuned on task-specific data and provide a bridge between the general capabilities of the LLM and the specific requirements of the task at hand. This approach allows for more effective knowledge transfer and improved performance on supervised tasks, overcoming the limitations of ICL and the challenges associated with the size and inaccessibility of LLMs.
## How Do People Find out Small Models Are Valuable Plug-Ins for Large Language Models?
In this section, we are going to discuss the paper titled "Small Models are Valuable Plug-ins for Large Language Models" by Canwen Xu, Yichong Xu, Shuohang Wang, Yang Liu, Chenguang Zhu and Julian McAuley from University of California, San Diego and Microsoft. Like always, if the research details do not interest you, feel free to skip to the next section.
### Method
Based on the recognition of LLMs' limitations, which we have discussed in the previous section, the authors propose SuperICL to combine LLMs with locally fine-tuned smaller plug-in models. The plug-in model is first fine-tuned on the task-specific supervised dataset. It then makes predictions with confidence scores on the training examples from this dataset. These predictions are provided as context to the LLM along with the test input. The LLM utilizes this context to make the final prediction and can optionally generate an explanation for its reasoning.
### Experiment Design
They evaluate on the GLUE benchmark for natural language understanding tasks and on XNLI for zero-shot cross-lingual transfer. GPT-3.5 is used as the LLM and RoBERTa-Large/XLM-R as plug-in models. SuperICL is compared against baselines of ICL with GPT-3.5 and using only the plug-in models.
### Results
SuperICL outperforms both GPT-3.5 ICL and the plug-in models individually on the GLUE benchmark. On the XNLI dataset, SuperICL improves over XLM-R for most languages, demonstrating effective zero-shot transfer. An ablation study shows the importance of each component in the SuperICL approach.
### Wrap-Up
SuperICL achieves superior performance by combining the strengths of LLMs and smaller plug-in models fine-tuned on task data. It addresses the instability issue of regular ICL by separating language understanding from task-specific knowledge absorption. Additionally, SuperICL enhances the capabilities of smaller models like extending their multilinguality coverage. It also provides interpretability by allowing the LLM to generate explanations when overriding plug-in predictions.
## Real-life Cases of Small Models As Plug-Ins for Large Language Models
### Customized Customer Service Chatbots
Small, domain-specific models can be fine-tuned to understand the terminology and context of a particular industry and then used as plug-ins in a large chatbot framework to provide more accurate and relevant responses.
### Medical Diagnosis Assistance
A small model trained on medical records and literature can act as a plug-in for an LLM to assist doctors in diagnosing conditions, suggesting treatments, and interpreting medical tests more accurately.
### Legal Document Analysis
Small models fine-tuned on legal documents can be used to enhance LLMs in parsing and understanding legal contracts, providing summaries, and highlighting potential issues or clauses.
### Language Translation
For low-resource languages, small models can be trained on the available data and then used as plug-ins in LLMs to improve translation quality and handle nuances better.
### Educational Tools
Small models tailored to educational content can be integrated with LLMs to create intelligent tutoring systems that provide personalized feedback and explanations to students.
### Content Moderation
Small models trained to detect specific types of content (e.g., hate speech, explicit content) can be used to enhance the capabilities of LLMs in moderating user-generated content on social media platforms.
### Healthcare Monitoring
Small models trained to recognize patterns in patient data can be used to provide early warnings or insights into potential health issues when integrated with an LLM that can process and analyze larger datasets.
These applications demonstrate how the combination of specialized knowledge from small models with the broad understanding of LLMs can lead to more efficient, accurate, and tailored solutions in various professional and personal contexts.

## Limitations of Small Models As Plug-Ins for Large Language Models
### Dependency on plug-in model performance
The overall performance of SuperICL is still reliant on the quality of the locally fine-tuned plug-in model. If the plug-in model performs poorly on the task, it may limit SuperICL's effectiveness.
### Computational cost
Fine-tuning the plug-in model requires access to sufficient computational resources. For very large supervised datasets, this fine-tuning may become prohibitively expensive for smaller research groups or individuals.
### Task generalizability
The experiments focus on natural language understanding tasks in the GLUE benchmark. While promising, more evaluation is needed to assess SuperICL's effectiveness on other NLP tasks like generation, summarization, translation etc.
### Cross-task transfer
It's unclear how well a single plug-in model fine-tuned on one task can generalize and provide effective context for an entirely different task when used with SuperICL.
### Multilinguality limits
While SuperICL enhances multilinguality, its cross-lingual abilities are still fundamentally limited by the original multilingual capabilities of the plug-in model like XLM-R.
## Conclusion
The integration of small models as plug-ins with LLMs, as demonstrated by SuperICL, offers a compelling solution to the inherent limitations of large-scale AI. By augmenting the capabilities of LLMs, we pave the way for more nuanced, efficient, and broadly applicable AI systems. Yet, challenges such as dependency on plug-in performance, computational costs, and task generalizability persist, urging a balanced approach to harnessing this synergy.

The short answer to... | 0 | 2024-06-17T10:47:07 | https://dev.to/novita_ai/are-emergent-abilities-of-large-language-models-a-mirage-or-not-33nd | llm | ## Introduction
Are emergent abilities of large language models a mirage? The short answer to this question is: mostly, yes. Some scholars from Stanford argue that it's all about metrics. To be specific, [**LLMs**](https://blogs.novita.ai/top-10-llm-models-on-hugging-face/) develop their abilities gradually, not abruptly according to most metrics, while these emergent miracles only show up in certain metrics. In this blog, we explore the original definition of emergent abilities of large language models, how these scholars challenge the claim and implications of their findings in the AI world.
## What Are Emergent Abilities of Large Language Models?
**Emergent abilities** refer to new capabilities or behaviors that arise in complex systems as they scale up in size or complexity. In the context of LLMs, these are unexpected skills or improvements in performance that supposedly weren't present in smaller models but appear as the model grows.
### Characteristic 1: Sharpness
**Sharpness** in the context of emergent abilities refers to the sudden and dramatic increase in performance on a specific task. It's as if the model has a "lightbulb moment" where it transitions from not being able to perform a task at all to doing it flawlessly. This is often visualized as a steep curve on a graph, showing performance metrics like accuracy or task completion rate jumping from a low value to a high one without much in-between.
Imagine you have a series of language models with varying sizes, from small to very large. You test their ability to translate text from English to French. The smaller models might struggle, providing poor translations with many errors. However, as you test larger and larger models, you might suddenly find that at a certain size, the model's translations are almost perfect, with very few, if any, errors. This sudden improvement is what is referred to as the "sharpness" of the emergent ability.
### Characteristic 2: Unpredictability
**Unpredictability** is about the difficulty in foreseeing when or at what size a model will exhibit an emergent ability. There isn't a clear, gradual trend that you can point to and say, "When we reach this size or complexity, the model will be able to do X." Instead, the appearance of these abilities seems to come out of the blue, without any obvious pattern or warning.
Continuing with the translation example, you might expect that as you increase the size of the model, its translation ability will steadily improve. However, unpredictability means that you can't reliably predict at which exact model size the translations will become excellent. One model might show a leap in ability when it has 100 million parameters, while another might not show the same leap until it has a billion parameters. There's no clear rule that tells you when this will happen, making the emergence of the ability unpredictable.
## Challenging the Emergence Claim: Just A Mirage
The article titled "Are Emergent Abilities of Large Language Models a Mirage?" by Rylan Schaeffer, Brando Miranda, and Sanmi Koyejo from Stanford University's Computer Science department, challenges the notion that LLMs exhibit emergent abilities. As always, if you are not interested in the research details, just grab this takeaway and move to the next section: **perceived "emergent abilities" in large language models may actually be an illusion created by the choice of performance metrics** rather than a genuine and abrupt change in the models' capabilities as they scale up in size.
### Research Background & Research Question
The article begins by discussing the concept of emergent properties in complex systems, which has gained attention in machine learning due to observations of large language models (LLMs) displaying abilities not seen in smaller models. These emergent abilities are characterized by their sharpness and unpredictability.
The research question posed by the article is whether these emergent abilities are a fundamental property of scaling AI models or an artifact of the metrics used to measure performance.
### Experiment Design
The authors propose an alternative explanation for emergent abilities, suggesting that they may be a result of the choice of metric rather than intrinsic model behavior. They present a mathematical model to demonstrate this and test their hypothesis through three complementary approaches:
1. They tested their idea using a well-known AI model family (InstructGPT/GPT-3) on tasks where people said these special skills showed up. They looked at how changing the test scores (metrics) changed what we see.
2. They conducted a meta-analysis of emergent abilities on a bunch of tests (BIG-Bench) to see if these special skills only showed up when using certain ways of scoring (metrics).
3. They induced seemingly emergent abilities in multiple vision tasks across diverse deep networks by changing evaluation metrics.
### Findings
- **The Test Results:** When the researchers changed the way they measured the AI's performance (the metrics), they saw something interesting. Instead of a sudden jump in the AI's abilities, they found a smooth and steady improvement as the AI models got bigger. This was the opposite of what they expected if the AI really had "special skills" that appeared out of nowhere.
- **Different Metrics, Different Stories:** They found that certain ways of measuring performance made it look like the AI got a lot better really fast. But when they used different metrics that graded the AI more fairly, the improvements were more gradual. It was like the AI wasn't suddenly getting smarter; it was just being tested in a way that made it look that way.
- **The Big Test (Meta-Analysis):** When they looked at a bunch of different tests (the BIG-Bench), they saw that these "special skills" only showed up when certain metrics were used. It was like these skills were hiding and only appeared when the test was set up in a certain way.
-** Making Skills Appear:** Finally, the researchers showed that they could make these "special skills" appear in other types of AI tasks (like recognizing pictures) just by changing how they measured the AI's performance. It was like magic, but instead of a real magic trick, it was about how they were looking at the AI's abilities.
## Implications for AI Research and Development
### Metric Selection
Researchers should carefully consider the choice of metrics when evaluating AI models. The paper suggests that nonlinear or discontinuous metrics might create a misleading perception of model capabilities. Choosing appropriate metrics that accurately reflect gradual improvements is crucial for valid and reliable assessment.
### Benchmark Design
The design of benchmarks should take into account the potential influence of metric choice on the perceived abilities of AI models. Benchmarks should use a variety of metrics to provide a comprehensive assessment and avoid overemphasizing results from metrics that might induce the appearance of emergent abilities.
### Interpretation of Results
Researchers should be cautious when interpreting results that suggest emergent abilities. The paper encourages a more nuanced understanding of model performance, taking into account the possibility that observed 'emergent' behaviors might be artifacts of the measurement process.
### Model Transparency and Reproducibility
The paper highlights the importance of making models and their outputs publicly available for independent verification. This transparency is essential for the scientific community to validate claims and reproduce results, ensuring the integrity of AI research.
### AI Safety and Alignment
If emergent abilities are perceived to arise unpredictably, it could have implications for AI safety and alignment. However, if these abilities are a result of metric choice, it suggests that researchers have more control over the development of AI capabilities than previously thought, which could be leveraged to guide AI development towards beneficial outcomes.
### Resource Allocation
Understanding that emergent abilities might be a mirage can inform resource allocation in AI development. Instead of focusing on scaling models to achieve unpredictable abilities, resources might be better spent on refining algorithms, datasets, and training processes to produce desired outcomes in a more predictable manner.
### Ethical Considerations
The ethical implications of AI capabilities are closely tied to our understanding of what AI can and cannot do. If emergent abilities are less common or less abrupt than believed, this could affect how we approach ethical guidelines and regulations for AI development and deployment.
### Public Communication
Communicating AI capabilities to the public accurately is important for managing expectations and addressing concerns about AI. The paper's findings suggest that caution should be exercised to avoid overstating AI capabilities and to provide a clear and realistic picture of AI's current and potential future abilities.
### Research Prioritization
The findings might lead researchers to prioritize understanding the fundamental mechanisms behind AI performance improvements over searching for elusive emergent abilities. This could involve more focus on algorithmic improvements, data quality, and training techniques.
## Get Hands-on Experience with LLM's Capabilities
Although the authors deny LLM's capabilities as emerging, they do not indicate that LLM's capabilities are not solid. LLMs' abilities to solve problems in real-life scenarios are unquestionable. If you are eager to get hands-on experience with LLM's capabilities, Novita AI provides AI startups with [**LLM APIs**](https://novita.ai/llm-api) to leverage the power of LLMs.

## Conclusion
The debate on whether large language models (LLMs) exhibit genuine emergent abilities or if these are a mirage, as suggested by researchers from Stanford, brings into focus the pivotal role of performance metrics in AI evaluation. The study posits that the sharp and unpredictable improvements attributed to LLMs may be an artifact of certain metrics rather than an intrinsic model capability.
This perspective prompts the AI community to reconsider the design of benchmarks and the interpretation of results, advocating for transparency, diverse metrics, and a deeper understanding of AI's incremental progress. The implications are clear: as we advance AI research, we must critically examine the tools of our assessment to ensure a realistic and ethical development path that aligns with societal expectations and safety standards.

I was asked in our most recent [virtual event](https://workshops.code-maven.com/): What is your strategy to promote Rust?
My short answer was that I don't have a strategy as I don't see as my goal to make companies switch to Rust. Besides, who am I to be able to convince companies to switch to Rust?
Thinking about it a bit more I realized I do have a strategy.
I would like to make Rust more accessible, easier to learn by running these [virtual workshops in English](https://workshops.code-maven.com/). I also just opened a new Meetup group called [Rust in Israel](https://www.meetup.com/rust-in-israel/) that I'll use to organize in-person events in Israel and virtual events in Hebrew.
I'll use these platforms to provide opportunities to the local Rust developers to showcase the fun stuff they work on and to the local companies can showcase how and why they decided to use Rust.
I believe the more than 100 [Rust user groups](https://rust.code-maven.com/user-groups) provide similar opportunities.

1,891,058 | Starting from Scratch in IT in 2024: Things you shouldn't worry about | Intense competition among juniors, AI taking over jobs, and ongoing crises – why these shouldn’t... | 0 | 2024-06-17T10:38:23 | https://dev.to/vorniches/starting-from-scratch-in-it-in-2024-things-you-shouldnt-worry-about-4p17 | productivity, beginners, career, ai | Intense competition among juniors, AI taking over jobs, and ongoing crises – why these shouldn’t deter you if you’ve decided that IT is your path, and how hard work and self-belief aren’t just Disney thinking.
In the comments on my previous post about [career lessons](https://dev.to/vorniches/ive-worked-in-it-for-over-10-years-here-are-5-things-i-wish-i-knew-when-i-started-43pe), many people recognized themselves. However, there were also some reasonable concerns from other experienced developers who had tough experiences on their way. I want to address these and some other concerns that I’ve encountered from people starting a new path as IT specialists.
## On Competition
The first concern is the high level of competition. Yes, there are many juniors, and there always have been more candidates than job openings! I was rejected from jobs 100 times more than I was accepted. This is normal and expected. However, what’s truly lacking are adequate people. There’s a global crisis of adequate people. If you can realistically assess your skills and abilities, are willing to learn, and don’t give up, you will find your place in any profession and location. The key is consistency and a willingness to learn. If you don’t get the job but learn from the experience, you improve and increase your chances for successful interviews in the future.
Don’t chase money. While working for free isn’t ideal, if you have an internship with the potential for a job or can stretch your current savings or work part-time, it’s worth trying. Even if you don’t land the job, it’s still valuable experience. Use it wisely to increase your chances.
My first job in test automation paid around $300 a month. This was much less than my previous income from web development, and I searched for it for six months, facing rejections and being ignored along the way. However, I got an offer for my next testing job in just three days, and my earnings nearly quadrupled. This isn’t a universal "success" formula, but sometimes, when you’re on the right path, such things happen.
Yes, competition is high, but adequate people who can learn, adapt, and stay positive will always find their place in the market. Don’t fear rejections – use them as opportunities for growth and to increase your chances of future success.
## AI is Your Friend, Not Your Enemy
I understand the concerns about AI in programming, especially from those who haven’t used it. Headlines might make it seem like AI will soon replace everyone. Artists are already being replaced, and coders are next (haha).
Seriously, the most significant change with AI in programming in the near future is that it will become a standard part of the workspace. For example, officially provided by employers, in code editors, and with paid access to services like ChatGPT. This won’t reduce the number of jobs, but being able to work with AI can become a competitive advantage.
As a junior or potential junior, AI can be a great mentor at the beginning. It can guide you on starting projects from scratch, what to do when stuck, help write code, and debug errors. For beginners, if used correctly, AI can accelerate learning tenfold; for experienced developers, it can boost productivity tenfold. Of course, you can’t rely on it 100%, but over time, AI becomes smarter, less buggy, and more useful. I speak from experience. When GitHub released the Copilot beta, even before ChatGPT, I used it. When ChatGPT-3 appeared, I was among the first users. What the latest version, ChatGPT-4o, can do today is astonishing. The key is to communicate with it correctly, and if you lack experience, verify what it provides. Use traditional search and even a second opinion from another AI, like using ChatGPT as the main tool and verifying with Perplexity.ai.
If you’re stuck, don’t know what to do next, and don’t want or can’t talk to real people, AI is your best friend.
## What About the Crisis?
When wasn’t there a crisis? There were a few relatively calm years, especially in IT, but that’s over. Overall, crises are beyond your control. What can you do? Focus on what you can change – your life and profession if that’s what you desire.
Many companies hired extensively during the Covid, now, mass layoffs are happening. But there was a shortage in skilled professionals, is it changed globally? No. There's still a significant deficit of skilled professionals, particularly those who are truly capable. Businesses are finding it hard to fill positions with qualified individuals. This shortage of adequate talent means that those who can learn, adapt, and stay positive are in high demand. There are still plenty of opportunities for those who are ready to work hard and develop their skills. Learn, gain experience, go to interviews, and seize opportunities. This isn’t Disney thinking – it’s a principle of development in life. You either develop, improve, and find your place, or give up, make excuses, and change nothing.
If it takes four years to change your profession, what would be better for you – achieving the life you want in four years or remaining the same person in four years, having done nothing? This is life, and you need to take control where you can and not worry about what you can’t influence.
## A Little Life Example
If you don't speak russian, the message on the screenshot is from my friend Vlad (name changed), and in this message, Vlad shares with me the joy of successfully completing his probation period at his first job in IT.
Vlad started exploring what he could do in IT just over two years before I received his message in February 2024. Vlad chose a direction and persistently pursued it. Sometimes he doubted himself, sometimes he worried about failing, but advice and words of support from someone who had been through it helped him not give up and keep going.
He studied, went to interviews, faced rejections or was ignored. He learned from this experience and got better until he finally became the person for the job he got. Is this a happy ending? Oh no, it’s the beginning of a new stage, new challenges, and a new path. Only now, Vlad is learning not between shifts at a factory (this is not a figure of speech), but at the job he dreamed of – a Java backend developer in a major enterprise. I don’t know how he knew this was his calling from the start and not frontend like I might have suggested, but that only increases my respect and pride for him.
---
I, too, tried to get entry-level positions many times and was often rejected. I kept learning until I started getting positions slightly above entry-level. In some ways, it’s even easier for you today – you have AI. AI has concentrated experience and can greatly assist you, providing guidance if you ask the right questions.
Don’t fear competition, AI, or the crisis. The main thing is to be adequate, learn, and not give up. There’s always a place in the world for those willing to work hard and develop.

1,891,076 | Decorator Pattern | Step-by-Step Guide to Implementing the Decorator Pattern The Decorator Pattern is a... | 0 | 2024-06-17T10:25:21 | https://dev.to/muhammad_salem/decorator-pattern-1adl | designpatterns, softwaredesign, oop | ### Step-by-Step Guide to Implementing the Decorator Pattern
The Decorator Pattern is a structural design pattern that allows you to dynamically add behavior to an object without affecting the behavior of other objects from the same class. It provides a flexible alternative to subclassing for extending functionality.
#### 1. Understand the Concept
The Decorator Pattern involves the following key components:
- **Component Interface**: An abstract class or interface that defines the operations.
- **Concrete Component**: A class that implements the Component interface.
- **Decorator**: An abstract class that implements the Component interface and has a reference to a Component object.
- **Concrete Decorators**: Classes that extend the Decorator class and add functionalities to the Component.
#### 2. Define the Example Scenario
Let's consider a real-world example: A coffee shop where you can order different types of coffee and add various condiments (like milk, sugar, and whipped cream) dynamically.
#### 3. Implementing the Example
**Step 1: Define the Component Interface**
First, create an interface or abstract class for the coffee:
**Step 2: Create Concrete Components**
Next, create concrete implementations of the Coffee class:
```csharp
public class Espresso : Coffee
{
public override string GetDescription()
{
return "Espresso";
}
public override double Cost()
{
return 1.99;
}
}
public class HouseBlend : Coffee
{
public override string GetDescription()
{
return "House Blend Coffee";
}
public override double Cost()
{
return 0.89;
}
}
```
**Step 3: Create the Decorator Abstract Class**
Create an abstract decorator class that implements the Coffee interface and holds a reference to a Coffee object:
```csharp
public abstract class CoffeeDecorator : Coffee
{
protected Coffee _coffee;
public CoffeeDecorator(Coffee coffee)
{
_coffee = coffee;
}
public override string GetDescription()
{
return _coffee.GetDescription();
}
public override double Cost()
{
return _coffee.Cost();
}
}
```
**Step 4: Create Concrete Decorators**
Now, create concrete decorators that extend the CoffeeDecorator class and add functionalities:
```csharp
public class Milk : CoffeeDecorator
{
public Milk(Coffee coffee) : base(coffee)
{
}
public override string GetDescription()
{
return _coffee.GetDescription() + ", Milk";
}
public override double Cost()
{
return _coffee.Cost() + 0.50;
}
}
public class Sugar : CoffeeDecorator
{
public Sugar(Coffee coffee) : base(coffee)
{
}
public override string GetDescription()
{
return _coffee.GetDescription() + ", Sugar";
}
public override double Cost()
{
return _coffee.Cost() + 0.20;
}
}
public class WhippedCream : CoffeeDecorator
{
public WhippedCream(Coffee coffee) : base(coffee)
{
}
public override string GetDescription()
{
return _coffee.GetDescription() + ", Whipped Cream";
}
public override double Cost()
{
return _coffee.Cost() + 0.70;
}
}
```
**Step 5: Use the Decorators**
Finally, use the decorators to dynamically add functionalities to the coffee objects:
```csharp
class Program
{
static void Main(string[] args)
{
Coffee myCoffee = new Espresso();
Console.WriteLine($"{myCoffee.GetDescription()} ${myCoffee.Cost()}");
myCoffee = new Milk(myCoffee);
Console.WriteLine($"{myCoffee.GetDescription()} ${myCoffee.Cost()}");
myCoffee = new Sugar(myCoffee);
Console.WriteLine($"{myCoffee.GetDescription()} ${myCoffee.Cost()}");
myCoffee = new WhippedCream(myCoffee);
Console.WriteLine($"{myCoffee.GetDescription()} ${myCoffee.Cost()}");
// Output:
// Espresso $1.99
// Espresso, Milk $2.49
// Espresso, Milk, Sugar $2.69
// Espresso, Milk, Sugar, Whipped Cream $3.39
}
}
```
### Summary
- **Step 1**: Define a Component interface or abstract class.
- **Step 2**: Create Concrete Components that implement the Component interface.
- **Step 3**: Create an abstract Decorator class that also implements the Component interface and holds a reference to a Component object.
- **Step 4**: Create Concrete Decorators that extend the Decorator class and add functionalities.
- **Step 5**: Use the decorators to dynamically add behaviors to the component.
By following these steps, you can implement the Decorator Pattern to add functionalities to objects dynamically, keeping your design flexible and adherent to the Open/Closed Principle. This approach helps in maintaining a clean and extendable codebase. | muhammad_salem |

1,891,067 | How to Use NPM Libraries that Might get Deprecated..!📦 | In the world of JavaScript development, utilizing third-party libraries from npm (Node Package... | 0 | 2024-06-17T10:17:04 | https://dev.to/nirmeet_gandhi/how-to-use-npm-libraries-that-might-get-deprecated-516k | javascript, react, npm, packagemanager | In the world of JavaScript development, utilizing third-party libraries from npm (Node Package Manager) is common practice. However, what happens when a library you rely on becomes deprecated or is no longer maintained?
**Fear not!!**
This blog will guide you through the process of effectively using and customizing deprecated npm libraries to fit seamlessly into your projects.🛠️
**Understanding the Challenge**
Imagine you’ve built a fantastic feature in your application using a popular npm library, let’s say react-credit-cards-2. Over time, the library's development slows down, and eventually, it's marked as deprecated in npm. This means no more updates, no bug fixes, and potentially, no support for new features or security patches.
😕As a responsible developer, you know you need to transition away from it. Here’s how you can approach this:
**Step-by-Step Guide**
**Locate the Library**
- Start by searching for the deprecated library on npm or directly on GitHub. For instance, you might find the repository for react-credit-cards-2 at [github.com/flequis/react-credit-cards-2](https://github.com/felquis/react-credit-cards-2).
**Download the Repository**
- Instead of cloning the repository using Git, you can download the source code directly from GitHub:
- Navigate to the GitHub repository for the library (github.com/flequis/react-credit-cards-2).
- Click on the green Code button.
- Select Download ZIP to download the repository as a ZIP file to your local machine.📥
**Customize the Library**
- Extract the downloaded ZIP file to access the library’s source code. Look for the src folder which typically contains the main codebase of the library. Remove any unnecessary files or folders that won’t be used in your project.
**Organize Your Project**
- Create a new directory within your project’s structure, let’s call it custom-component. Inside this directory, create a folder named after the library (e.g., react-credit-cards-2). Move the contents of the src folder from the extracted repository into this newly created folder.📂
**Use the Customized Library**
- Instead of importing the library directly from npm, import it from your customized version. You might create an index.js or index.ts file inside your library folder to export all necessary components or functions.
```
// Example of using the customized library
import CreditCardForm from './custom-libraries/react-credit-cards';
function App() {
return (
<div>
<CreditCardForm />
</div>
);
}
```
**Why Customize?**
Customizing deprecated npm libraries allows you to:
- Maintain Control: You can fix bugs or add features specific to your project’s needs.
- Security: Ensure security updates are applied if the library was deprecated due to vulnerabilities.
- Longevity: Extend the life of a library until you can find a suitable replacement.🕒
**Conclusion**
While using deprecated npm libraries isn’t ideal, it’s sometimes necessary. By following these steps, you can effectively manage and customize deprecated libraries, ensuring your projects remain stable and secure. Remember, always keep an eye out for alternative libraries or updates that may eventually replace your customized solution.
**Additional Tips**🌟
- Documentation: Maintain documentation on your customization, especially if other team members are involved.
- Community Support: Engage with the community. you might not be alone in facing this challenge.
- Migration Plan: Start planning for migration to a supported library as soon as feasible.
By mastering the art of customizing deprecated npm libraries, you can navigate through transitions smoothly and keep your projects up-to-date and efficient.
Happy coding! 🚀

1,891,066 | Building a Blogging Platform with the MERN Stack | Introduction As a MERN stack developer, one of the best ways to hone your skills and build... | 0 | 2024-06-17T10:16:17 | https://raajaryan.tech/building-a-blogging-platform-with-the-mern-stack | javascript, beginners, programming, tutorial | ### Introduction
As a MERN stack developer, one of the best ways to hone your skills and build a comprehensive portfolio is to create real-world applications. In this article, we will build a simple yet functional blogging platform using the MERN stack (MongoDB, Express, React, Node.js). This project will cover user authentication, CRUD operations for blog posts, and basic responsive UI design.
### Project Overview
Our blogging platform will allow users to:
- Register and log in
- Create, read, update, and delete blog posts
- Comment on posts
- Navigate through a responsive user interface
### Technology Stack
- **Frontend:** React
- **Backend:** Node.js and Express
- **Database:** MongoDB
- **Authentication:** JWT (JSON Web Tokens)
### Setting Up the Project
#### 1. Backend Setup
We start by setting up the backend, which will handle user authentication, post creation, and data management.
##### Initialize the Backend
1. **Create and Navigate to the Backend Directory:**
```bash
mkdir blog-platform
cd blog-platform
mkdir backend
cd backend
npm init -y
npm install express mongoose dotenv jsonwebtoken bcryptjs
```
2. **Create the Project Structure:**
```
backend/
├── models/
├── routes/
├── controllers/
├── middleware/
├── .env
├── server.js
```
3. **Set Up the Server (`server.js`):**
```javascript
const express = require('express');
const mongoose = require('mongoose');
const dotenv = require('dotenv');
dotenv.config();
const app = express();
app.use(express.json());
const connectDB = async () => {
let connected = false;
while (!connected) {
try {
await mongoose.connect(process.env.MONGO_URI, {
useNewUrlParser: true,
useUnifiedTopology: true,
});
console.log('Connected to MongoDB');
connected = true;
} catch (err) {
console.error(err.message);
console.log('Retrying MongoDB connection in 5 seconds...');
await new Promise(res => setTimeout(res, 5000)); // Wait 5 seconds before retrying
}
}
};
connectDB();
const server = app.listen(process.env.PORT || 5000, () =>
console.log(`Server running on port ${process.env.PORT || 5000}`)
);
// Graceful shutdown
process.on('SIGTERM', () => {
console.info('SIGTERM signal received.');
console.log('Closing http server.');
server.close(() => {
console.log('Http server closed.');
mongoose.connection.close(false, () => {
console.log('MongoDb connection closed.');
process.exit(0);
});
});
});
```
4. **Configure Environment Variables (`.env`):**
```
MONGO_URI=your_mongo_connection_string
JWT_SECRET=your_jwt_secret
```
##### Create Models
1. **User Model (`models/User.js`):**
```javascript
const mongoose = require('mongoose');
const UserSchema = new mongoose.Schema({
username: { type: String, required: true, unique: true },
email: { type: String, required: true, unique: true },
password: { type: String, required: true }
});
module.exports = mongoose.model('User', UserSchema);
```
2. **Post Model (`models/Post.js`):**
```javascript
const mongoose = require('mongoose');
const PostSchema = new mongoose.Schema({
title: { type: String, required: true },
content: { type: String, required: true },
author: { type: mongoose.Schema.Types.ObjectId, ref: 'User' },
createdAt: { type: Date, default: Date.now }
});
module.exports = mongoose.model('Post', PostSchema);
```
##### Create Controllers
1. **User Controller (`controllers/userController.js`):**
```javascript
const User = require('../models/User');
const bcrypt = require('bcryptjs');
const jwt = require('jsonwebtoken');
exports.register = async (req, res) => {
const { username, email, password } = req.body;
try {
const hashedPassword = await bcrypt.hash(password, 10);
const newUser = new User({ username, email, password: hashedPassword });
await newUser.save();
res.status(201).json(newUser);
} catch (error) {
res.status(400).json({ message: error.message });
}
};
exports.login = async (req, res) => {
const { email, password } = req.body;
try {
const user = await User.findOne({ email });
if (!user) return res.status(400).json({ message: "User not found" });
const isMatch = await bcrypt.compare(password, user.password);
if (!isMatch) return res.status(400).json({ message: "Invalid credentials" });
const token = jwt.sign({ id: user._id }, process.env.JWT_SECRET, { expiresIn: '1h' });
res.json({ token, user: { id: user._id, username: user.username, email: user.email } });
} catch (error) {
res.status(400).json({ message: error.message });
}
};
```
##### Create Routes
1. **User Routes (`routes/userRoutes.js`):**
```javascript
const router = require('express').Router();
const { register, login } = require('../controllers/userController');
router.post('/register', register);
router.post('/login', login);
module.exports = router;
```
2. **Post Routes (`routes/postRoutes.js`):**
```javascript
const router = require('express').Router();
const Post = require('../models/Post');
router.post('/', async (req, res) => {
const { title, content, author } = req.body;
try {
const newPost = new Post({ title, content, author });
await newPost.save();
res.status(201).json(newPost);
} catch (error) {
res.status(400).json({ message: error.message });
}
});
router.get('/', async (req, res) => {
try {
const posts = await Post.find().populate('author', 'username');
res.json(posts);
} catch (error) {
res.status(400).json({ message: error.message });
}
});
module.exports = router;
```
##### Create Middleware
1. **Auth Middleware (`middleware/auth.js`):**
```javascript
const jwt = require('jsonwebtoken');
const auth = (req, res, next) => {
const token = req.header('x-auth-token');
if (!token) return res.status(401).json({ message: "No token, authorization denied" });
try {
const decoded = jwt.verify(token, process.env.JWT_SECRET);
req.user = decoded;
next();
} catch (error) {
res.status(400).json({ message: "Token is not valid" });
}
};
module.exports = auth;
```
#### 2. Frontend Setup
##### Initialize the Frontend
1. **Create and Navigate to the Frontend Directory:**
```bash
npx create-react-app frontend
cd frontend
npm install axios react-router-dom
```
2. **Create the Project Structure:**
```
frontend/
├── public/
├── src/
├── components/
├── pages/
├── App.js
├── index.js
├── ...
```
##### Create Components
1. **Login Component (`components/Login.js`):**
```javascript
import React, { useState } from 'react';
import axios from 'axios';
const Login = ({ setAuth }) => {
const [email, setEmail] = useState('');
const [password, setPassword] = useState('');
const handleSubmit = async (e) => {
e.preventDefault();
try {
const res = await axios.post('/api/auth/login', { email, password });
setAuth(res.data.token);
} catch (error) {
console.error(error);
}
};
return (
<form onSubmit={handleSubmit}>
<input type="email" value={email} onChange={(e) => setEmail(e.target.value)} />
<input type="password" value={password} onChange={(e) => setPassword(e.target.value)} />
<button type="submit">Login</button>
</form>
);
};
export default Login;
```
2. **Register Component (`components/Register.js`):**
```javascript
import React, { useState } from 'react';
import axios from 'axios';
const Register = () => {
const [username, setUsername] = useState('');
const [email, setEmail] = useState('');
const [password, setPassword] = useState('');
const handleSubmit = async (e) => {
e.preventDefault();
try {
await axios.post('/api/auth/register', { username, email, password });
// Handle success, e.g., redirect to login
} catch (error) {
console.error(error);
}
};
return (
<form onSubmit={handleSubmit}>
<input type="text" value={username} onChange={(e) => setUsername(e.target.value)} />
<input type="email" value={email} onChange={(e) => setEmail(e.target.value)} />
<input type="password" value={password} onChange={(e) => setPassword(e.target.value)} />
<button type="submit">Register</button>
</form>
);
};
export default Register;
```
##### Create Pages
1. **Home Page (`pages/Home.js`):**
```javascript
import React, { useEffect, useState } from 'react';
import axios from 'axios';
const Home = () => {
const [posts, setPosts] = useState([]);
useEffect(() => {
const fetchPosts = async () => {
try {
const res = await axios.get('/api/posts');
setPosts(res.data);
} catch (error) {
console.error(error);
}
};
fetchPosts();
}, []);
return (
<div>
{posts.map(post => (
<div key={post._id}>
<h2>{post.title}</h2>
<p>{post.content}</p>
<small>By: {post.author.username}</small>
</div>
))}
</div>
);
};
export default Home;
```
### Advanced Features

1,891,065 | Classes in C# | Uzbek | Assalomu alaykum barchaga. Bugun biza C# dasturlash tilida Class tushunchasi bilan bog'liq miflarni... | 0 | 2024-06-17T10:15:14 | https://dev.to/ozodbek_soft/classes-in-c-uzbek-c7h | class, csharp, uzbek, dotnet | Assalomu alaykum barchaga. Bugun biza C# dasturlash tilida `Class` tushunchasi bilan bog'liq miflarni sindiramiz. Dastlab Classlar haqida gaplashsak. Class bu reference Type hisoblanadi. Va xotirada HEAP dan joy oladi.
C# dasturlash tilida `class` - bu Object-Oriented-Programming(OOP)ni asosiy tushunchalaridan biri hisoblanadi. Classlar yordamida yangi turdagi obekt yaratishingiz va ularga ishlov berish, methodlarni(function) guruhlashingiz mumkin.
**Class nima ?**
Class bu - obektlarning tuzilishi, xususiyatlari(properties), methodlar(functions)larni aniqlovchi shablon yoki qolib. Yuqorida aytganimizdek siz - Classlar yordamida yangi obektlarni yaratishingiz, ularga ishlov berishingiz va methodlarni guruhlashingiz mumkin bo'ladi.
**Classlar nima uchun kerak ?**
`- 1 - Ma'lumotlarni guruhlash: Classlar yordamida ma'lumotlar va methodlarni guruhlash imkoniyatiga ega bo'lamiz. Bu bizga codeni o'qish va yaxshi tushunish imkoniyatini beradi.
- 2 - Qayta foydalanish: Bir marta yaratilgan classdan ko'p joyda foydalanish mumkin. Bu esa codeni yaxshi ishlashini ta'minlaydi (100 xil nomli o'zgaruvchi yaratib o'tirmaysiz 🔥)
- 3 - Encasulation: Classlar ma'lumotlarni yashirish va ularga kirishni nazorat qilish, imkonini beradi.
- 4 - Inheritance: Bir class boshqa classlardan meros olib(nusxa olib), uning xususiyatlari va methodlarini o'zida saqlab qolishi mumkin.`
_Classlar haqida biroz nazariy bilimga ega bo'ldik. Endi undan foydalanishni bilib olamiz._
Person.cs
```
// Bir Person degan class yaratib olamiz
public class Person
{
// xususiyatlari 👇
public string Name { get; set; }
public int Age { get; set; }
// Salomlashish uchun Method
public void Greeting()
=> Console.WriteLine($"Assalomu alaykum. Mening ismim: "{Name}" va men {Age}") yoshdaman");
}
```
Yuqoridagi codeda bir inson haqida ma'lumotlarni olib salomlashish uchun bir method yaratdik. Endi shu class asosida bir obekt yaratib olamiz...
Program.cs
```
public class Program
{
// Yangi obekt hosil qilib olamiz. Person classi asosida
Person odam = new Person();
// Propertylarga value berib chiqamiz
odam.Name = "Ozodbek";
odam.Age = 17;
// Salomlashish uchun methodni ushbu obekt orqali ishlatib ko'ramiz
odam.Greeting();
}
```
Output:Terminal
```
Assalomu alaykum. Mening ismim **Ozodbek** va men 17 yoshdaman
```
Classlarni tushunib oldik. Endi Constructor haqida ham bir ikki shingil ma'lumot berib o'tmasam bo'lmaydi.
**Constructor** - _bu, classning obektini yaratishda automatic ravishda chaqiriladigan methoddir. Return type mavjud emas. Constructor yordamida boshlang'ich qiymatlarni berishimiz mumkin._
**Person.cs**
```
// Boyagi, Person deganda misol qilamiz
public class Person
{
// xususiyatlari 👇
public string Name { get; set; }
public int Age { get; set; }
// Constructor
public Person(string name, int age)
{
Name = name;
Age = age;
}
public void Greeting()
=> Console.WriteLine($"Salom mening ismim{Name}, Yoshim {Age} da")
}
```
Constructorni chiqaramiz
**Program.cs**
```
public class Program
{
public void Main()
{
Person odam2 = new Person("Ozodbek", 17);
odam2.Greeting();
}
}
```
**Inheritance** - bir class ikkinchi classdan meros olib uni xususiyatlari va mehtodlari o'zida saqlab qolishi uchun kerak.
**Inheritance** orqali ham ishlab ko'rishimiz kerak.
**Program.cs**
```
// Asosiy animal class
public class Animal
{
public string Name { get; set; }
public void speak()
=> Console>WriteLine($"The {Name} sound");
}
// Inheritance (meros) olamiz.
public class Dog : Animal
{
public void Color()
=> Console>WriteLine("Dog color is Black");
}
```
Program.cs
```
public class Program
{
public static void Main()
{
Dog kuchuk = new Dog();
kuchuk.Name = "Rex";
kuchuk.Speak();
kuchuk .Color();
}
}
```
**Output**
```
The Rex sound
Dog color is Black
```
**Xulosa**: Classlar bu C# dasturlash tilida asosiy tushuncha va u yordamida strukturalash, ma'lumotlarni guruhlash va hokazolarni qilish mumkin. O'rgangan misollarimizni review qilish orqali siz chuqurroq tushunib ham olishingiz mumkin(Classlarni). Bu misollar orqali bir sodda tilda tushuntirib berdik degan umiddaman😊

1,891,063 | Benefits of the Beehiiv Newsletter Platform for Content Creators | I would like to inform you that have moved all my articles and newsletter from medium.com to Beehiiv.... | 0 | 2024-06-17T10:13:33 | https://dev.to/samuel_olatubi/benefits-of-the-beehiiv-newsletter-platform-for-content-creators-3gkp | writing, productivity, news, google | I would like to inform you that have moved all my articles and newsletter from medium.com to Beehiiv. Why? Because the Beehiiv platform offers much more functionality, even in its free version. In my case, Beehiiv complements perfectly the free version of the marketing platform LeadsLeap and the modest newsletter on medium.com.
Luckily, I found Faith on Fiverr, and let me tell you, she did an amazing job! She transferred all my articles and newsletters smoothly, optimized them for SEO (which is a big plus!), and even used some really cool templates that look fantastic.
Seriously, I can't recommend her enough. If you're looking for some help with your content or want to explore monetization options on Beehiiv, Faith is your person! [Contact Faith here](https://www.fiverr.com/s/DBmw8Ko)
Beehiiv: A Powerful Newsletter Platform
IMHO, Beehiiv is one of the best newsletter platforms and provides a lot of essential features tailored for content creators. Let’s explore a few of them:
Monetization without membership fees
Beehiiv allows you to charge for newsletter subscriptions without taking a percentage of your revenue.
Good SEO optimization
Beehiiv offers an SEO-optimized website, ensuring better visibility for your content.
Without installation
No need to install any additional tools; Beehiiv simplifies the setup process.
Works as a blog + newsletter
You can publish content both as blog posts and email messages, maximizing your reach and engagement.
Many Integrations
Beehiiv provides API access and integrates with hundreds of popular web tools, expanding your capabilities.
Advanced email customization
With Beehiiv’s flexible email editor, you can create unique and visually appealing email messages.
Email analytics

Multiple newsletters per account
Manage multiple newsletters from one Beehiiv account, streamlining your content creation and distribution.
Leveraging LeadsLeap for Enhanced Marketing
What is LeadsLeap? It’s a comprehensive marketing platform that provides all the tools available in e-marketing for free. There is also a PRO version available, which includes more advanced features. However, I want to show that if something is missing in the free version, it can be replaced with an external tool.
The free LeadsLeap version includes:
Hosting
Mailing list
Landing and splash page builder
Traffic tracking and monitoring
Free advertisements
Codes that allow others to import and clone your site
And much more
Many of my subscribers using the free version complain about the lack of an automatic mailing list. That’s why I decided to combine Beehiiv with the free version of LeadsLeap to address this issue effectively.

Being able to use data structures and write your own algorithms for your day to day problems is one of the best things.
But even after watching a lot of videos and following tutorials, you may find yourself not being able to solve basic DSA problems.
I have recently found this platform CodeChef where you can practice problems on DSA.
I am going to list down all the data structures and algorithms which are present in this roadmap:
### Data structures
1. Linked Lists
2. Stacks
3. Queues
4. Matrices
5. Trees
6. Graphs
7. Heaps
8. Disjoint set union
9. Tries
### Algorithms
1. Greedy Algorithms
2. Two pointers
3. Prefix sums
4. Binary search
5. Recursion
6. Bit manipulation
7. Dynamic programming
8. Number theory
If you learn all this data structures and algorithms, and practice sufficient problems on them, you can easily become one a good developer.
You can find the roadmap here - https://www.codechef.com/roadmap/data-structures-and-algorithms
Even though you will not be implementing this DSA on your day to day job, but you will still be able to think on how to approach and solve the problems.
Happy coding! | justani |
