1,925,325 | AutoEntityGenerator – my first visual studio extension. | (First published on What The # Do I Know?) TL;DR – There are links to the Visual Studio Marketplace... | 0 | 2024-07-16T10:56:00 | https://dev.to/peledzohar/autoentitygenerator-my-first-visual-studio-extension-p9j | dotnet, visualstudio | (First published on [What The # Do I Know?](https://zoharpeled.wordpress.com/2024/07/16/autoentitygenerator-my-first-visual-studio-extension/))
TL;DR – There are links to the Visual Studio Marketplace and the GitHub repository at the end.
It all started when I watched a YouTube video by Amichai Mantinband called [Controllers From Scratch Using .NET 8](https://www.youtube.com/watch?v=RfFTVwQ9oT4),
where he shows how to properly design and build an ASP.NET Controller as a part of his ASP.NET 8 REST API Tutorial. (As a side point, I highly recommend subscribing to his YouTube channel).
One of the things he talked about in this video, was the structure of end points he follows and recommend – and this structure has three parts:
Mapping from request object to domain model
Acting on the domain model
Mapping the result of that action to a response object
The example he shows is creating a product, so let me quickly show you the code for this example:
```csharp
public IActionResult Create(CreateProductRequest request)
{
// mapping request to domain
var product = request.ToDomain();
// acting on domain object
_productService.Create(product);
// mapping domain to response and return to client
return CreatedAtAction(
actionName: nameof(Get),
routeValues: new { ProductId: product.Id },
value: ProductResponse.FromDomain(product)
);
}
```
Of course, in this video he creates the domain model, the different request and response DTOs, and the mapping methods between them – and this is what gave me the idea for my extension – which is a very simple idea: What if, instead of having to manually write all these DTOs and mappings, we would have a light bulb action that will generate all this code for us with just a few mouse clicks, using a simple form like the “Extract interface” form?
Armed with this idea and zero knowledge about visual studio extensions, I’ve called ChatGPT for help (and then also involved Claude.AI). The beginning was somewhat difficult since both of them sent me off to somewhat misleading directions, but after a few trials and errors, I’ve managed to get started with a simple POC that shows a light bulb menu item.
After that POC up and running it was time to start focusing on what I wanted the extension to do.
The first step was to get the menu item to only show when using the light bulb on a class or record definition – which was quite simple. Then I’ve used a lot of ChatGPT’s help with getting the information I needed from the code – the namespace, the class (or record) name, its constructors,
public properties, type parameters and other relevant information,
all collected into a class I’ve called Entity (and a bunch of other classes to go along with it such as Property, Namespace and so on):
```csharp
public class Entity
{
public Project Project { get; set; }
public Namespace Namespace { get; set; }
public string Name { get; set; }
public List<Constructor> Constructors { get; set; }
public string SourceFilePath { get; set; }
public List<Property> Properties { get; set; }
public List<string> TypeParameters { get; set; }
public List<string> GenericConstraints { get; set; }
}
```
Getting the entity information was basically a simple mapping between Microsoft.CodeAnalysis.CSharp.Syntax definitions to my own definitions, but it is a crucial step of the process.
The next step was to build the UI, which contains a form where the user can select which properties they want to include in the DTO, how to name it, what would be its file name, what directory to save it to, and which direction to generate the mapping.
The next step was to use the information from the UI to generate a new Entity object that represents the DTO, use then use that entity and the original one to generate the code for both the DTO and the mappings, and finally, save that code in new files in the user-selected directory.
It took me about 3-4 weeks of part-time work (about 25-30 work hours a week) to get the first version to a point I feel good enough about it to release it to the public – and there’s still quite a bit of work left to do on it, but IMHO it is good enough to work with and therefore good enough to be published.
As of now, it can only be installed on Visual Studio Community 2019 or 2022, but I plan to make it available for Professional and Enterprise editions as well in the (hopefully not too distant) future.
It’s completely open source and free to use, you can check it out on [GitHub](https://github.com/Peled-Zohar/AutoEntityGenerator) or in the [Visual Studio Marketplace](https://marketplace.visualstudio.com/items?itemName=ZoharPeled.AutoEntityGenerator).
If you’ve tried it, I would very much appreciate any feedback, good or bad. | peledzohar |

It returns:
- 0 if both values are equal
- 1 if left operand is greater
- -1 if right operand is greater
Let’s see it with an example:
```
echo 2 <=> 2; // Outputs 0
echo 3 <=> 1; // Outputs 1
echo 1 <=> 3; // Outputs -1
echo "b" <=> "b"; // Outputs 0
echo "a" <=> "c"; // Outputs -1
echo "c" <=> "a"; // Outputs 1
// Note: for string comparison, the ASCII value of the characters are used, that is why "c" is greater than "a"
echo "ping" <=> "pong"; // Outputs -1 since "o" is greater than "i"
```
This operator can be used for sorting arrays:
```
$numbers = [1, 4, 5, 9, 2, 3];
usort($numbers, function ($a, $b) {
return $a <=> $b; // Sort in ascending order
});
echo print_r($numbers); // Outputs [1,2,3,4,5,9]
usort($numbers, function ($a, $b) {
return $b <=> $a; // Sort in descending order
});
echo print_r($numbers); // [9,5,4,3,2,1]
```

They excel at grasping context, creating relevant content, answering questions accurately, and performing diverse NLP tasks effortlessly. LLMs are used in customer service, healthcare, finance, and E-Commerce to transform text handling and decision-making. This blog explores 9 impactful ways LLMs enhance user experiences from detailed product descriptions to medical diagnostics across industries.
## Understanding LLM
LLMs are advanced AI systems that understand and generate natural text by analyzing vast amounts of data. They can translate languages, determine sentiment in text, and create new content. LLMs have the potential to change written content across various industries, improving efficiency.
### What is LLM
An LLM is an advanced AI language model that greatly expands training and inference data. LLMs interpret and generate human language on a large scale. They operate through neural networks designed to mimic the human brain’s learning process. LLMs are extensively trained with vast amounts of text data, allowing them to understand and generate coherent responses to prompts in various uses.
### How does LLM work
An LLM is trained on a large data corpus and undergoes initial training on structured and unstructured data before proceeding to the transformer neural network phase.
After pre-training, the model can be fine-tuned for specific tasks using a smaller relevant dataset. During the training process, these models learn to predict the next word in a sentence based on the context provided by the preceding words and deep learning algorithms. Model performance can also be improved through prompt engineering, prompt-tuning, fine-tuning, and other tactics like reinforcement learning with human feedback.
## 4 Types of LLMs
LLMs come in various types. Generative AI models create human-like text for chatbots, virtual assistants, and content creation. Task-specific models specialize in language translation and sentiment analysis with specific training data.
### 1. Zero-Shot Models
Zero-shot models are known for their ability to perform tasks without specific training data. These models can generalize and make predictions or generate text for tasks they have never seen before.
Examples: GPT-3.5 Turbo, GPT-4
### 2. Multimodal Models
LLMs were initially designed for text content. However, multimodal models work with both text and image data. These models are designed to understand and generate content across different modalities.
Example: CLIP, SeamlessM4T, Gemini
### 3. Fine-tuned or Domain-Specific Models
While pre-trained language representation models are versatile, they may not always perform optimally for specific tasks or domains. Fine-tuned models have undergone additional training on domain-specific data to improve their performance in particular areas.
Examples: GPT-3 model, BERT, T5
### 4. Hybrid Models
Hybrid models leverage various architectures to boost performance. For instance, combining transformer-based designs with recurrent neural networks (RNNs) enhances sequential data processing by capturing both sequential dependencies and self-attention mechanisms within LLMs.
Examples: UniLM, Mixtral 8x22B (provided by Novita AI)

1,925,334 | From JS to Fire OS: React Native for Amazon Devices | React Native enables developers to build native apps for Amazon Fire OS devices using their existing... | 0 | 2024-07-17T10:12:49 | https://dev.to/amazonappdev/get-started-with-react-native-for-amazon-fire-os-51j8 | reactnative, beginners, react, learning | React Native enables developers to build native apps for Amazon Fire OS devices using their existing JavaScript and React skills. Since Fire OS is based on the Android Open Source Project (AOSP), if you are already working with React Native you can easily target our devices without learning a new tech stack or maintaining separate codebases.
We recommend using the Expo framework to build React Native apps as it enables an easier and faster development experience. Follow along to see how to get up and running with React Native for both Fire Tablets and Fire TVs.
## ✅ Pre-requisites for this guide
Install the following:
- [Node.js](https://nodejs.org/en/download/package-manager): The JavaScript runtime environment
- [npm](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm) or [Yarn](https://classic.yarnpkg.com/lang/en/docs/install/): Package managers for JavaScript
- [Android Studio](https://docs.expo.dev/get-started/set-up-your-environment/?platform=android&device=physical&mode=development-build&buildEnv=local#set-up-android-studio): the IDE used to compile and run your Fire OS apps locally
Configure Android Studio and its command-line tools:
1. Follow [this guide](https://developer.android.com/tools/variables) to set your `ANDROID_HOME` environment variable
2. Install the following emulators from [Android Studio’s virtual device manager](https://developer.android.com/studio/run/managing-avds):
| For Tablet: | For TV: |
| --------- |:---------:|
|  |  |
## 📱 Building for Fire Tablets
In the terminal, create a new React Native project with the expo package installed:
```sh
npx create-expo-app FireTabletDemo --template blank
```
### Running on Fire Tablet Emulator
List the available [avds](https://developer.android.com/studio/run/managing-avds) then launch the Android Tablet:
```sh
emulator -list-avds
emulator -avd name-of-your-tablet-emulator
```
Navigate to the project directory (e.g. FireTabletDemo) and run the app using npx:
```sh
cd FireTabletDemo
npx expo start -a
```
Your app is now running on the emulator using a local development server and Expo Go, without having to create the Android build.
### Running on a physical tablet device:
Follow the instructions [here](https://developer.amazon.com/docs/fire-tablets/connecting-adb-to-device.html) to connect your tablet via adb. Afterwards, confirm it is available as a device:
```sh
adb devices -l
```
Navigate to the project directory then run a development build on your target device (e.g. KFTRWI)
```sh
cd FireTabletDemo
npx expo run:android -d [deviceName]
```
The development build will now install within the android directory:
## 📺 Building for Fire TVs
To build apps for Fire TVs with React Native you can follow a similar journey.
In a new directory, create a new React Native project with the expo, this time using the with-tv example:
```sh
npx create-expo-app FireTVDemo -e with-tv
```
### Running on Android TV Emulator
Launch the Android TV emulator:
```sh
emulator -avd name-of-your-tv-emulator
```
Navigate to the project directory and run your app:
```sh
cd FireTVDemo
npx expo start -a
```
Similar to the Fire tablets, your app will run on the avd emulator without having to create the Android build:
### Target the build for TVs:
In order to build for TVs, set the isTV prop to true in your app.json:
```json
{
"expo": {
"plugins": [
[
"@react-native-tvos/config-tv",
{
"isTV": true,
}
]
],
"name": "FireTVDemo",
"slug": "FireTVDemo"
}
}
```
### Running your project on a Fire TV device
To connect your Fire TV, follow the instructions [here](https://developer.amazon.com/docs/fire-tablets/connecting-adb-to-device.html) then check that your device is connected using adb:
```sh
adb devices -l
```
Navigate to the project directory then run a development build on your target device (e.g. -d AFTSS)
```sh
cd FireTVDemo
npx expo run:android -d [deviceName]
```
You now have the development build installed on your device:
💡 You can verify your android builds are optimized for TV by checking that your app is using the [Android leanback features](https://developer.android.com/training/tv/get-started/create#leanback-req) in the Android manifest file.

---
In the ever-evolving landscape of web security, Content Security Policy (CSP) has emerged as a powerful tool to help developers protect their applications from various forms of attacks, particularly Cross-Site Scripting (XSS). This blog will take you through the fundamentals of CSP, how to implement it, and provide real-world examples to help you master its usage.
## What is Content Security Policy (CSP)?
Content Security Policy (CSP) is a security feature that helps prevent a range of attacks by controlling the resources that a website is allowed to load and execute. By defining a CSP, you can specify which scripts, styles, and other resources can be loaded, thereby significantly reducing the risk of XSS and data injection attacks.
## Why Use CSP?
**1. Mitigate XSS Attacks:** By restricting the sources from which scripts can be loaded, CSP helps prevent attackers from injecting malicious scripts.
**2. Control Resource Loading:** CSP allows you to control from where your site loads resources such as images, scripts, stylesheets, and more.
**3. Prevent Data Injection:** CSP can help prevent attacks that aim to inject unwanted data into your site.
## Basic Structure of a CSP
A CSP is defined using the Content-Security-Policy HTTP header. Here’s a simple example of what a CSP header might look like:
```js
Content-Security-Policy: default-src 'self'; script-src 'self' https://trusted.cdn.com; style-src 'self' 'unsafe-inline'
```
In this policy:
**default-src 'self':** By default, only allow resources from the same origin.
**script-src 'self' https://trusted.cdn.com:** Allow scripts from the same origin and a trusted CDN.
**style-src 'self' 'unsafe-inline':** Allow styles from the same origin and inline styles.
## Implementing CSP in Your JavaScript Application
### Step 1: Define Your Policy
Start by determining which resources your application needs to load. This includes scripts, styles, images, fonts, etc.
```html
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self' https://trusted.cdn.com; style-src 'self' 'unsafe-inline'; img-src 'self' data:;">
```
### Step 2: Add CSP Header to Your Server
If you're using an Express.js server, you can set the CSP header as follows:
```js
const express = require('express');
const helmet = require('helmet');
const app = express();
app.use(helmet.contentSecurityPolicy({
directives: {
defaultSrc: ["'self'"],
scriptSrc: ["'self'", "https://trusted.cdn.com"],
styleSrc: ["'self'", "'unsafe-inline'"],
imgSrc: ["'self'", "data:"],
}
}));
app.listen(3000, () => {
console.log('Server is running on port 3000');
});
```
### Step 3: Test Your CSP
Once your CSP is in place, test it thoroughly. Use browser developer tools to check if any resources are being blocked. Adjust the policy as necessary to ensure your application functions correctly while remaining secure.
## Example: Implementing CSP in a Sample Project
Let’s consider a simple HTML page that loads scripts and styles from a trusted CDN.
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self' https://cdnjs.cloudflare.com; style-src 'self' 'unsafe-inline';">
<title>Secure CSP Example</title>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/normalize/8.0.1/normalize.min.css">
</head>
<body>
<h1>Content Security Policy Example</h1>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
<script>
$(document).ready(function() {
console.log('jQuery is working!');
});
</script>
</body>
</html>
```
In this example:
- Only resources from the same origin ('self') are allowed by default.
- Scripts are allowed from the same origin and from the cdnjs.cloudflare.com CDN.
- Inline styles are permitted ('unsafe-inline'), but this should be avoided if possible for better security.
## Tips for a Strong CSP
**1. Avoid 'unsafe-inline' and 'unsafe-eval':** These allow inline scripts and styles, which can be exploited. Use nonce-based or hash-based policies instead.
**2. Use Report-Only Mode:** Start with Content-Security-Policy-Report-Only to log violations without enforcing the policy, allowing you to fine-tune the policy.
**3. Regularly Update CSP:** As your application evolves, ensure your CSP is updated to reflect new resource requirements and security best practices.
## Conclusion
Implementing a robust Content Security Policy is a critical step in securing your JavaScript applications against a range of attacks. By understanding the fundamentals of CSP and following best practices, you can significantly enhance the security posture of your web applications. Start with a basic policy, test it thoroughly, and iterate to achieve the perfect balance between functionality and security.

1,925,337 | Implementing Photo Modal in Next JS using Parallel Routes & Intercepting Routes | Implementing Modals using parallel routes & intercepting routes provided in Next JS app router... | 0 | 2024-07-16T11:08:39 | https://dev.to/wanyama413/implementing-photo-modal-in-next-js-using-parallel-routes-intercepting-routes-2dpn | nextjs, javascript, webdev, frontend | Implementing Modals using parallel routes & intercepting routes provided in Next JS app router offers the following benefits:
1.Ability to share the modal content using a url
2.Preserving context when the page is refreshed, instead of closing the modal.
3.Closing the Modal on backward navigation & re-opening the modal on forward navigation
Why use with Parallel Routes?
Parallel Routes in Next JS are created by defining ‘slots’ which is a folder created by prepending an ‘@’ before the folder name e.g @modal or @photogrid
Paralle Routes work same way as Componentization where you can have different UI blocks in a single page with their own routes and logic. Using parallel routes however have the following benefits:-
Parallel Routes can be streamed independently, allowing you to define independent error and loading states for each route.
Next.js will perform a partial render, changing the subpage within the slot, while maintaining the other slot’s active subpages, even if they don’t match the current URL.
These 2 Routing techniques would therefore help us to implement a modal in Next JS and make sure that:
We can share the Modal through a url (Intercepting Routes)
On page refresh or shareable link navigation, modal context is preserved. (Intercepting Routes)
Keeping the context of the photo grid when navigating a modal (Parallel Routes)
In your app directory, create a blogs folder with the following logic to create a photo grid in its page.jsx file
```
import Link from "next/link";
import blogs from "../../blogs";
import Image from "next/image";
const Blogs = () => {
return (
<div className="grid grid-cols-2 place-items-center place-content-center gap-5 sm:grid-cols-4">
{blogs.map((blog) => {
return (
<article key={blog.id}>
<Link href={`/blogs/${blog.title}`}>
<Image alt={blog.title} src={blog.url} width={250} height={250} />
</Link>
</article>
);
})}
</div>
);
};
export default Blogs;
```
Then create a dynamic route for each photo from the grid,
```
import React from "react";
import blogs from "../../../blogs";
const Blog = ({ params }) => {
const find = blogs.find((blog) => blog.title == params.title);
return <div>{find.title}</div>;
};
export default Blog;
```
Then create a parallel route by creating a folder in the app directory starting with an @ as in the screenshot below @modal.
Every parallel route must have a default.js file for when the page gets refreshed and only one of the routes is matched by Next JS, the content in the default.jsx file gets displayed for the other slots. On our case we return a null as we only want to show a modal when the user clicks on a photo.
Inside the @modal slot create an intercepting route which intercepts the blog route we create earlier. If the slot is in the same segment as the intercepted route, you use only a single dot i.e (.) followed by the folder name of the intercepted route folder name.
(.) to match segments on the same level
(..) to match segments one level above
(..)(..) to match segments two levels above
(...) to match segments from the root app directory
You might say since the (.)blogs is inside the @modal folder which is inturn inside the app folder then it is 1 segment above but parallel routes/slots do not affect routing, you can’t navigate to /slots.
Inside the intercepted route dynamic route i.e page.jsx file, paste the following code
```
import React from "react";
import blogs from "../../../../blogs";
import Modal from "@/components/Modal";
import Image from "next/image";
const InterceptedRoute = ({ params }) => {
const finder = blogs.find((blog) => blog.title == params.title);
return (
<Modal>
<article>
<Image src={finder.url} alt={finder.title} width={400} height={400} />
</article>
</Modal>
);
};
export default InterceptedRoute;
```
The code to the modal component is
```
"use client";
import { useCallback, useRef, useEffect, MouseEventHandler } from "react";
import { useRouter } from "next/navigation";
export default function Modal({ children }: { children: React.ReactNode }) {
const overlay = useRef(null);
const wrapper = useRef(null);
const router = useRouter();
const onDismiss = useCallback(() => {
router.back();
}, [router]);
const onClick: MouseEventHandler = useCallback(
(e) => {
if (e.target === overlay.current || e.target === wrapper.current) {
if (onDismiss) onDismiss();
}
},
[onDismiss, overlay, wrapper]
);
const onKeyDown = useCallback(
(e: KeyboardEvent) => {
if (e.key === "Escape") onDismiss();
},
[onDismiss]
);
useEffect(() => {
document.addEventListener("keydown", onKeyDown);
return () => document.removeEventListener("keydown", onKeyDown);
}, [onKeyDown]);
return (
<div
ref={overlay}
className="fixed z-10 left-0 right-0 top-0 bottom-0 mx-auto bg-black/60 "
onClick={onClick}
>
<div
ref={wrapper}
className="w-[100%] absolute top-1/2 left-1/2 -translate-x-1/2 -translate-y-1/2 sm:w-10/12 md:w-8/12 lg:w-2/5 p-6"
>
{children}
</div>
</div>
);
}
```
The slot can now be accessed as a prop in the root layout:-
```
import React from "react";
import "./globals.css";

1,925,338 | Deploying Spring boot project to external tomcat server. | Although spring boot project comes with tomcat server itself. But sometimes we may have requirements... | 0 | 2024-07-16T11:10:22 | https://dev.to/shoili_rozario_76aefaf1d8/deploying-spring-boot-project-to-external-tomcat-server-37g8 | Although spring boot project comes with tomcat server itself. But sometimes we may have requirements to make our spring boot application on an external tomcat server. So, keeping knowledge on how we can deploy our spring boot project on external tomcat server is a plus point for every spring boot learner.
## Building the spring boot project:
I have a simple project with a home route, which is showing "Hello World" to the browser.
Now that I have my controller set up. Now I need to extend my **DemoApplication** class to **SpringBootServletInitializer** and should override the function configure just like I have shown below.
```
....
....
@SpringBootApplication
public class DemoApplication extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(DemoApplication.class);
}
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
```
I will now update my pom.xml file.
`<packaging>war</packaging>`
```
<!--for tomcat deployment -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
```
This image will make things clearer.
```
<build>
<finalName>my-app-2</finalName>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
```
Adding _**finalName**_ in the pom.xml will be helpful if you want to give custom .war file which we are going to get after the build process.
## Build our Spring boot project:
Now let's build our newly created spring boot application.
`mvn clean package`
It will build your spring boot application and will make a folder named **target** in your root folder.
my-app-2.war is my required war file which can be used later on to deploy my web application to tomcat server.
## Installing Tomcat Server:
Now that we have .war file, lets install tomcat zip file from its official website. After download the zip file we need to extract that file and keep the extracted folder in the C-drive of our computer.
Note that you have to take compatible tomcat server for your application otherwise you cannot view your deployed app. As my spring boot version is 3.3.1, I have downloaded tomcat version 10. Check your spring boot version then choose the right version of your tomcat server.
Now let's run our tomcat server using startup.bat command in windows. The file is in the bin directory.
So, our tomcat server is running perfectly. Let's take the .war file from our spring boot project to tomcat servers webapps folder.
Just paste your .war file and wait for 2 to 3 seconds. The server will automatically extract the folder out of the .war file. In the following image you can see I have my-app-2.war file, which is extracted to my-app-2 folder by the tomcat server itself.
Now restart the tomcat server and your application will be accessible on http://localhost:8080/my-app-2/
I have changed my tomcat port to 8081 but you will see your app on 8080 as its default port.
Thank you.

• Metric: Total Visits, Unique Visitors, Traffic Sources (Organic, Paid, Referral)
• Importance: Indicates the reach and visibility of the website. Analyzing traffic sources helps allocate marketing budgets effectively.
**2. Conversion Rate**
• Metric: Conversion Rate (%)
• Importance: Measures the percentage of website visitors who complete a desired action (e.g., filling out a form, making a purchase). A higher conversion rate indicates effective marketing and website optimization.
**3. Cost per Acquisition (CPA)**
• Metric: CPA
• Importance: Evaluates the cost-effectiveness of marketing campaigns by calculating the average cost to acquire a customer or lead. Lower CPA indicates efficient campaign management.
**4. Return on Investment (ROI)**
• Metric: ROI (%)
• Importance: Measures the profitability of marketing campaigns relative to the investment made. Positive ROI indicates that marketing efforts generate more revenue than the cost incurred.
**5. Customer Lifetime Value (CLTV)**
• Metric: CLTV
• Importance: Predicts the total revenue a customer is expected to generate throughout their relationship with the business. Helps prioritize customer retention and acquisition strategies.
**6. Email Marketing Metrics**
• Metrics: Open Rate, Click-through Rate (CTR), Conversion Rate
• Importance: Evaluates the effectiveness of email campaigns in engaging and converting subscribers. High open and CTRs indicate strong content relevance and audience engagement.
**7. Social Media Engagement**
• Metrics: Likes, Shares, Comments, Followers Growth
• Importance: Measures audience interaction and brand affinity on social platforms. High engagement rates indicate effective content strategies and brand resonance.
**Implementing KPI Tracking**
To effectively track and utilize KPIs:
• Define Clear Objectives: Align KPIs with specific marketing goals such as lead generation, brand awareness, or sales.
• Utilize Analytics Tools: Implement robust analytics platforms (e.g., Google Analytics, HubSpot) to track and analyze KPI data in real-time.
• Regular Monitoring and Reporting: Establish regular reporting schedules to review KPI performance, identify trends, and make data-driven decisions.
• Continuous Optimization: Use insights from KPIs to refine marketing strategies, allocate budgets effectively, and improve campaign performance over time.
**Conclusion**

1,925,347 | Growth Hacking Vs. Growth Marketing: How Are They Different? | “Growth hacking” and “growth marketing” are terms often used interchangeably by many. In fact I find... | 0 | 2024-07-16T11:18:09 | https://dev.to/niumatrix_digital_5b43412/growth-hacking-vs-growth-marketing-how-are-they-different-2l0k | marketing, seo, growthhacking, growthmarketing | “Growth hacking” and “growth marketing” are terms often used interchangeably by many. In fact I find it astonishing how people bandy about “growth hacker” or “growth marketer” in their LinkedIn headlines without any consideration for what exactly are these terms and how are they different from each other.
Growth hacking and growth marketing carry different connotations and focus areas. Both concepts are geared towards achieving business growth, but they employ distinct approaches and methodologies.
While growth hacking tends to focus on quick wins and rapid growth through creative and often aggressive tactics, growth marketing is about incorporating the insights gained from those tactics into a consistent, scalable and long term strategy. The tactics deployed for growth marketing are often the part of the brand’s essence and its key differentiating factor.
Growth hacking can be seen as a subset of growth marketing, utilized typically during the early stages of a product or business launch. Brands often outgrow growth hacking tactics and in the long run adopt any of those tactics as a long term business growth strategy. At that point a growth hacking strategy becomes a growth marketing strategy.
Tinder’s Swipe feature is a good example. It was a unique way to accept or reject profiles and was introduced as a growth hack to make the app more engaging and fun. But it has become so popular since then that it has become a defining feature of Tinder as a brand.
Both growth hacking and growth marketing are essential for businesses, and the choice between focusing on growth hacking or growth marketing often depends on the stage of the business, the business goals, and the available resources.
Let’s understand the differences between growth hacking and growth marketing.
Growth Hacking
Definition: Growth hacking is a technique developed by startups which uses creative, low-cost strategies to help businesses acquire and retain customers. Essentially, it involves experimenting across product and marketing channels to identify the most effective, efficient ways to grow a business.
Focus: It is heavily focused on rapid experimentation across marketing funnels, product development, sales segments, and other areas to identify the most efficient ways to grow a business.
Scope: Typically limited in scope to specific campaigns or initiatives aimed at increasing a company’s customer base or market share quickly and with minimal expenditure.
Process: Growth hacking focuses heavily on experimentation and iteration. Different growth features are developed, tested, and refined over time.
Tools & Techniques: Growth hacking techniques can be broadly categorized into three buckets – product led growth hacking, where you develop features in your product that lead to viral adoption; engineering led growth hacking, where you develop additional free plugins, tools, that create a massive customer acquisition funnel for you; and marketing led growth hacking where you leverage marketing channels that give you extra ordinary returns.
Endpoint: The end goal is rapid growth, often disregarding the traditional pathways or longer-term branding strategies.
Growth Marketing
Definition: Growth marketing extends traditional marketing by adding layers of experimentation and performance metrics to more traditional marketing tactics. It seeks to optimize and find innovative ways across the entire customer lifecycle, from awareness through retention and referrals.
Focus: It looks at creating sustainable growth through data-driven marketing techniques and focuses on engaging users by creating value through every touch point with a brand.
Scope: Broader than growth hacking, as it includes building brand loyalty and delivering long-term value to ensure not just acquisition but also customer retention and brand loyalty.
Process: Growth marketing is algorithmic in the sense that is all about identifying winning patterns and optimizing those that work.
Tools & Techniques: Growth marketing involves utilizing various strategies such as product engagement features, SEO, content marketing, influencer marketing, A/B testing, email marketing automation, data analytics, and user journey optimization.
Endpoint: The emphasis is on building a sustainable brand alongside growth. It is as much about retaining and engaging existing users as gaining new ones.
Let’s understand the difference between growth hacking and growth marketing with a few examples of very well-known success stories.
Examples of Growth Hacking
Dropbox Referral Program
Strategy: Dropbox used a simple yet powerful referral program that leveraged its existing user base to drive growth. They incentivized users by offering extra storage space for both the referrer and the referee.
Result: This directly encouraged users to share Dropbox with their friends and family, significantly boosting user growth without traditional advertising spend.
Hotmail’s Email Signature
Strategy: At the end of every email sent from a Hotmail account, the company added a signature that said, “PS: I love you. Get your free Email at Hotmail.” This simple hack turned every email sent by a Hotmail user into a potential Hotmail ad.
Result: It contributed substantially to Hotmail’s viral growth, reaching millions of users rapidly.
Airbnb’s Craigslist Integration
Strategy: In its early days, Airbnb offered a platform for users to post their rental listings to Craigslist automatically, albeit using an unofficial method. This exposed Airbnb’s listings to a much larger audience who were already looking for accommodation solutions.
Result: This significantly boosted Airbnb’s user base and helped establish it as a go-to platform for short-term rentals.
Instagram’s Seamless Social Sharing
Strategy: When Instagram first launched, it allowed users to seamlessly share their Instagram posts on other social media platforms like Facebook, Twitter, and Tumblr. This strategy leveraged the existing user bases of these larger platforms.
Result: This created a viral loop that boosted Instagram’s visibility and user growth. Each shared photo acted as a natural advertisement for Instagram, attracting new users who wanted to engage with this new, visually-centered social platform.
PayPal’s Signup and Referral Bonuses
Strategy: In its early days, PayPal offered new users a cash incentive (initially $10, later reduced) for signing up and an additional cash bonus for referring friends.
Result: This direct financial incentive motivated users to join and share PayPal with others, resulting in exponential growth that helped establish PayPal as a leader in online payment solutions.
LinkedIn’s “People You May Know” Feature
Strategy: LinkedIn introduced the “People You May Know” feature, which uses algorithmic recommendations to suggest potential connections. This made it easier for users to find colleagues and encouraged more connections and interactivity on the platform.
Result: This feature significantly increased user engagement and network growth, as users were more likely to join and stay active on the platform if they could easily connect with others.
Tinder’s Swipe Feature
Strategy: Tinder revolutionized the online dating scene with its simple and addictive swipe feature, which gamified the process of finding a match. Users swipe right to like another user and left to pass, enabling quick and intuitive browsing of potential matches.
Result: This distinctive feature helped differentiate Tinder from other dating apps, making it easy and fun to use, which contributed to its rapid user growth.
Uber’s Surge Pricing Algorithm
Strategy: Uber uses a dynamic pricing model called “surge pricing” which increases prices during high-demand periods. This not only manages supply and demand but also incentivizes more drivers to get on the road during these times.
Result: Surge pricing helped Uber maximize availability and reliability, attributes that greatly contributed to its rapid growth in multiple cities worldwide.
Twitter’s Suggested Follows and Hashtags
Strategy: Twitter encourages new users to follow other popular accounts and interact with trending hashtags. This immediate engagement upon sign-up helps new users find interesting content and become active participants quickly.
Result: This approach helps to keep the platform dynamic and engaging, boosting user growth and retention by quickly integrating new users into the community.
Examples of Growth marketing
HubSpot’s Inbound Marketing
Strategy: HubSpot is a pioneer in inbound marketing, offering an array of tools including content management, social media scheduling, email marketing, SEO, and more. They focus heavily on providing valuable content through their blogs, free tools, and courses, drawing users into their ecosystem.
Result: This approach has helped establish HubSpot as a thought leader in the marketing industry, fostering strong customer loyalty and consistent growth in subscriptions.
L’Oréal’s Beauty Squad Influencer Campaign
Strategy: L’Oréal UK leveraged influencers to reach broader demographics. They built a community called the “Beauty Squad,” made up of influential beauty bloggers and vloggers. The influencers created content and shared their experiences using L’Oréal products across their personal channels.
Result: This strategy helped L’Oréal engage with younger audiences in a more personalized and trustworthy manner, boosting product awareness and sales.
Netflix’s Use of Big Data
Strategy: Netflix uses big data analytics to understand viewer preferences, helping to inform their content creation and acquisition strategies. They track various metrics to predict what users might want to watch next and customize content recommendations accordingly.
Result: By continually optimizing user experiences and ensuring high content relevancy, Netflix maintains high engagement rates, minimizes churn, and steadily increases its user base globally.
Amazon Prime
Strategy: Amazon developed Prime, a subscription service offering free shipping, exclusive access to movies, TV shows, ad-free music, Kindle books, and more. Prime is designed to increase customer loyalty and the frequency of purchases.
Result: Prime members tend to spend more and shop more frequently than non-Prime members, significantly boosting Amazon’s revenue and reinforcing its market dominance.
American Express Open Forum

1,925,406 | Python - Fundamentals | In here, I'm gonna tell you how to use variables in python. We shall see how to name a variable and... | 0 | 2024-07-16T14:00:46 | https://dev.to/abys_learning_2024/python-fundamentals-346p | python, coding, basic | In here, I'm gonna tell you how to use variables in python. We shall see how to name a variable and assign values to them.
**_How to name a Variable ?_**
Firstly a variable is nothing but a reference to an object or value throughout the program. They act as reference to a memory where the value is stored.
There are certain rules to name them.
- Must begin with a letter (a-z, A-Z) or an underscore (_).
- After the first character, letters, digits (0-9), or underscores can be followed.
- Variable names are case-sensitive.
For ex, myName and myname are entirely different variables.
- Should not use Python reserved words as variable names
For ex: class, def, for, while.
So, in python the operator = is used for assigning values to variables.
```
# Assigning integer value
age = 18
print(age)
18
# Assigning string value
name = "Arif"
print(name)
Arif
# Assigning float value (float means decimal value)
height = 2.5
print(height)
2.5
# Assigning boolean value (rfrs to true/false)
is_student = True
print(is_student)
True
```
**_Varible Types_**
Python is a typed lang, we needn't declare the type of a variable when assigning a value to it. The type is inferred by its own.
```
name = "Abys"
print(name)
print(type(name))
Abys
<class 'str'>
```
or we can also define the type by,
```
name = "Abys"
type(name)
str
age = 18
type(age)
int
```
That's the basic.
---
I've been asked to complete some questions on my own, lemme discuss those with you guys.
It's much easier to learn right...?
_1. Create a variable named name and assign your name to it. Then print the value of the variable._
```
name = "Abys"
print(name)
print(type(name))
Abys
<class 'str'>
```
_2. Create a variable age and assign your age to it. Later, reassign the variable with a new value and print the new value._
```
age=17
print("Present age:",age)
age= 18
print(age)
Present age: 17
18
```
and here if we want the type;
```
print(type(age))
<class 'int'>
```
_3. Assign the values 5, 10, and 15 to three variables a, b, and c in a single line. Print their values._
```
a,b,c = 5,10,15
print(a,b,c)
5 10 15
```
if we wanna add them we get,
```
print(a+b+c)
30
```
_4. Swap the values of two variables x and y without using a third variable. Print their values before and after swapping._
```
x,y = 5,25
print(x,y)
print(x-y)
x,y = 25,5
print(x,y)
print(x-y)
5 25
-20
25 5
20
```
they've asked just to print the swapped values, it's me who did extra stuffs.
Before the next qn we ought to know what is constants...
**_What are Constants ?_**
In Python, constants are those values that are not meant to change. By convention, they are typically written in capital letters with underscores separating the words.
However, in python constants can also be changed.
_5. Define constants PI with appropriate values and print them._
```
PI=3.14159
print(f"{PI:.3f}")
3.142
```
_6. Write a program that calculates the area of a circle using the constant PI and a variable radius. Print the area._
```
PI=3.14
radius=7
r=radius
area=PI*r**2 # r**2 refers to r pow 2
print("Area of circle is",area)
Area of circle is 153.86
```
_7. Define constants for the length and width of a rectangle. Calculate and print the area._
```
L,B = 5,15
area = L*B
print("Area of rect is ",area)
Area of rect is 75
```
These were the qns I worked on. Hope it is clear.
Sorry, if I'm ain't clear enough.., as I've just started blogging I may make mistakes.
Definitely will improve myself.
Thank you, All...

1,925,399 | Help the Poor and Needy – Make this World a Better Place | Originally Published by Lovely Foundation : https://www.lovelyfoundation.com/ngo-helping-poor This... | 0 | 2024-07-16T11:21:46 | https://dev.to/lovely_foundations_/help-the-poor-and-needy-make-this-world-a-better-place-d76 | ngoinmohali, educationngo | Originally Published by Lovely Foundation : https://www.lovelyfoundation.com/ngo-helping-poor
This world is full of capabilities, but numerous people don’t get a chance to experience it. The class divide in our society persists, favoring only a few. Where some people can make use of the best luxuries out there, many still struggle with arranging two meals a day. Forget about the basic necessities of life, poor people are battling severe hunger and thirst. The consequences of poverty are extreme and create immense challenges for those suffering from it. Lovely Foundation, an [NGO helping the poor](https://www.lovelyfoundation.com/), takes initiatives against the lack of food, water, clothing, and medical facilities.
Underprivileged people are constantly facing a lack of resources. This trial is beyond food and water. It makes children and adults vulnerable to malnutrition and diseases. Their lack of education makes them susceptible to child labour, violence, and abuse. It is the responsibility of society to take measures against poverty so that this world becomes a better place.
Non-governmental organizations have a role to play in eradicating poverty and helping the poor. Their commitment toward the needy and poor can bring a positive change not just in the lives of people but can also uplift society.
## The Role of Lovely Foundation in Helping the Poor
**Eliminating Hunger**
Underprivileged people are constantly struggling with the shortage of food. Lack of proper food makes people prone to multiple diseases that have acute effects on the body. Children suffer from malnutrition which affects their overall physical and mental development. In the case of adults, diseases like high blood pressure, heart disease and diabetes have prolonged repercussions. Food is necessary for the complete well-being of a person. Everybody needs food to lead a healthy and happy life.
Lovely Foundation is an NGO helping poor prone to lack of food. This Foundation in Mohali believes in the fact that no one deserves to sleep on an empty stomach. The volunteers of the organization find out about the vulnerable areas of society and distribute food to the needy. They make sure that the food prepared has the required nutritional value to fulfill the needs of the body.
**Empowering Children**
Education is the only powerful tool that can bring a favorable change in the lives of poor people. When a child gets a quality education, he becomes capable of creating opportunities and earning a living. Education has ripple effects that slowly bring big changes in the lives of individuals and society. It is the ultimate tool to get out of the vicious cycle of poverty. It makes children more confident and self-reliant in this unjust and unequal society.
Lovely Foundation abides by the fact that education is a fundamental right that must be available to all. The volunteers of the foundation arrange awareness and education camps in rural areas to bring consciousness among people for education. The idea is that every child must be entitled to free education and for this the foundation provides financial aid and mentorship to poor children.
**Eradicating Poverty**
Poverty is unforgiving as it takes a toll on those who suffer from it. Exposure to lower socio-economic standards negatively impacts individuals and makes them prone to various health risks. These risks range from heart disease, diabetes and hypertension to cancer, infant mortality and mental illness. It is our social responsibility to eliminate the root cause of this evil from society.
Lovely Foundation takes measures for the reduction, relief and alleviation of poverty. The foundation understands that poverty reduction will not only improve the lives of underprivileged people but will also result in overall economic growth. The volunteers of the NGO constantly work towards solving this problem by providing aid in health, education and infrastructure.
**Focus on Healthcare**
Underdeveloped areas lack health infrastructure and poor people don’t even have access to primary healthcare. People suffering from chronic diseases, pregnant women, and children need quality healthcare in case of emergencies. Other than that, it is a great contributor to the improved lives of the people. Better health encourages underprivileged society to move a step forward in the fight against poverty.
Lovely Foundation is an NGO helping the poor in such adverse conditions. It tries to create easy access to maternal health and medical supplies for children, adults, and old people. It also provides ambulances for vulnerable areas. The volunteers organize health camps that are equipped with proper medicines, point-of-care tests, and specialized healthcare providers.
**Bottom Line**
Numerous people are trapped in the clutches of poverty. It is limiting their experience of life, making them more vulnerable day by day. The resources of this land must not be confined to a privileged class of people. The poor need our help, together we can make this world a better place where no one is hungry, uneducated, or without the necessities of life.
Lovely Foundation takes a pledge to serve society and bridge the gap between disparity and a better life. The volunteers work relentlessly to provide food, education, and health to poor people. | lovely_foundations_ |

Morning! Another simple project under my belt and could be under yours! With the tutorial guidance of Tim from Tech with Tim at: [Youtube Link](https://www.youtube.com/watch?v=Dn1EjhcQk64) I was able to program a personal finance tracker. This project used a csv file to store transactions from the terminal line with pandas and uses matplotlib to plot the data for you to see. This is a great project for python beginners looking to explore popular libraries!
Project:
The program prompts users to enter transaction details such as date, amount, category (Income or Expense), and description, which are then stored in a CSV file. Users can view a summary of their income, expenses, and net savings for any given period, and generate plots to see trends and patterns in their financial data.
The project was both challenging and rewarding. Validating user inputs to ensure data integrity, handling CSV files for data storage, and creating meaningful visualizations were some of the key tasks. This experience highlighted the importance of robust input validation, efficient data handling, and the power of data visualization in understanding financial habits.
To Do:
This project and concept is a great base to make something bigger! Ideas I can think of is making a simple GUI that implements the original functions, or perhaps creating a django site. You could add more functionalities. The sky's the limit.
Lesson:
Following projects is a great tool for learning, but working on your own idea or building off an idea yourself is equally important. I will work off this project and be back to share my creation. In addition, following these projects are crucial for building a greater computer science background and experience. I plan to learn about webscraping, ai chatbots, and django with youtube. Following different topics through videos extends your knowledge a ton and can allow you to start thinking of ways to connect them all. Youtube is the best.
Thank you for reading. Thanks again to Tim from Tech with Tim. The repo for this project can be found here [GitHub Link](https://github.com/techwithtim/Personal-Finance-Tracker)

Go to routes/web.php
and add middleware to your route or route group just remember the key which will be using throughout the application in this case I am using `weather` as key to limit the request by User or IP. just remember whatever key you use should be same as the key in app/Providers/AppServiceProvider.php
so my route/web.php should look like this when I use the middleware with the single route
```
Route::get('/your-url', function () {
return response()
->json([
'data' => 'data will be here'
]);
})->middleware(['throttle:weather']);
```
or if you want to use route group
```
Route::middleware(['throttle:weather'])->group(function () {
// User CRUD controller
Route::resource('/users', UserController::class);
// Change Password View
Route::get('/profile/change-password', [UserController::class, 'changePassword'])->name('change.password');
// Change Password Store
Route::post('/profile/change-password', [UserController::class, 'changePasswordStore'])->name('change.password.store');
});
```
Than inside your app/Providers/AppServiceProvider.php within boot method you can limit the user or ip make sure to import the following namespaces
```
<?php
namespace App\Providers;
use Illuminate\Cache\RateLimiting\Limit;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\RateLimiter;
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider
{
/**
* Register any application services.
*/
public function register(): void
{
//
}
/**
* Bootstrap any application services.
*/
public function boot(): void
{
RateLimiter::for('weather', function (Request $request) {
return Limit::perMinute(10)
->by($request->user()?->id ?: $request->ip()); // 10 request per minute per user or ip
});
}
}
```
of if you want to limit normal user vs logged in user use the following.
```
<?php
namespace App\Providers;
use Illuminate\Cache\RateLimiting\Limit;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\RateLimiter;
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider
{
/**
* Register any application services.
*/
public function register(): void
{
//
}
/**
* Bootstrap any application services.
*/
public function boot(): void
{

It can enhance the interactive experience, improve the level of satisfaction of users, and save on redesign and development efforts.
- Measures User Behavior
The behavior of users can be measured with the help of Usability testing. It is worth noting that users are bad at articulating the things that they are looking for. But when behavior is observed and measured, it can be easier to find out what supports their objectives and inspires them the best.
It is often that website owners and in-house developers cannot view their website from a fresh perspective. With usability testing, it can be easier to look from a new angle and concentrate on all those features that actually matter to end-users.
- Reduces Costs
Competitive advantage can be gained in the form of reduction of support costs. When users can get a reliable website experience, mainly when competing businesses rank next in the search results, it is possible to get a solid website experience. When almost every company, including big brands, is trying to cut down on costs in every possible way, it can be beneficial to use usability testing to reduce expenses on development and design that are unlikely to attract users.
- Higher Guarantee of Success
With testing before implementing, it can be much easier to ensure success for brands. It is a truth that most businesses fail to have a blueprint, but Usability Testing gives them one. They can work on the same and have better chances of improving the [UX (User Experience)](https://www.peppersquare.com/ui-ux-design/).

As a new dev, don't be embarrassed to say,
"I'm currently in the middle of something. Let me get this done first, then I will jump on that."
Stop volunteering for everything.
Get your one assignment, understand the requirements well, and then knock out the park.
Be a dev that always delivers over one that is always in the middle of 10 different things.

1,925,423 | Cloning Reactive Objects in JavaScript | Cloning an object in JavaScript is a common operation, but when it comes to cloning reactive objects,... | 0 | 2024-07-16T11:44:56 | https://dev.to/akshayashet/cloning-reactive-objects-in-javascript-2h8f | vue, reactive, clone, javascript | Cloning an object in JavaScript is a common operation, but when it comes to cloning reactive objects, there are some additional considerations to keep in mind, especially when working with frameworks such as Vue.js or React. In this article, we'll explore how to properly clone reactive objects and provide examples using Vue.js.
**Shallow Cloning vs. Deep Cloning**
When it comes to cloning objects, it's important to understand the difference between shallow cloning and deep cloning. Shallow cloning creates a new object with the same top-level properties as the original object, but the nested objects within the original object are still referenced in the new object. Deep cloning, on the other hand, creates a completely new object with all nested objects also cloned.
**Cloning Reactive Objects in Vue.js**
In Vue.js, objects that are part of the component's data are made reactive using the Vue reactivity system. When cloning reactive objects in Vue.js, it's important to ensure that the reactivity is preserved in the cloned object. Vue provides the `Vue.util` object, which contains several utility methods for working with reactive objects. One of these methods is `Vue.util.defineReactive`, which can be used to define a reactive property on an object.
**Example: Cloning a Reactive Object in Vue.js**
```javascript
// Original reactive object
const originalObject = Vue.observable({
name: 'John',
age: 30,
});
// Cloning the reactive object
const clonedObject = {};
for (let key in originalObject) {
Vue.util.defineReactive(clonedObject, key, originalObject[key]);
}
```
In this example, we first create the original reactive object using `Vue.observable`. Then, we clone the object by iterating over its properties and using `Vue.util.defineReactive` to define each property on the new object.
It's important to note that this method only performs a shallow clone, meaning that any nested objects within the original object will still be referenced in the cloned object. If deep cloning is required, an additional deep cloning utility, such as Lodash's `_.cloneDeep`, can be used to ensure that all nested objects are also cloned.
In conclusion, when working with reactive objects in frameworks like Vue.js, it's crucial to handle object cloning with care to preserve reactivity and avoid unintended side effects. By using the appropriate methods and utilities, such as those provided by Vue.js itself or third-party libraries, developers can safely clone reactive objects while maintaining reactivity and data integrity. | akshayashet |

## Introduction
If you’re working in an architecture with multiple services talking to each other (call it microservices, SOA, or whatever), one pattern usually emerges quite quickly and also reemerges occasionally. I’m talking about the idea of providing a set of libraries that include clients for talking to the respective services. There are variations of this pattern, like sharing types for domain entities between services by putting them in a library. Just like Sam Newman also writes in [Building Microservices](https://samnewman.io/books/building_microservices_2nd_edition/), I also agree that this pattern is harmful. Let’s explore my reasoning by first diving into why this seems like a good idea at first glance.
## Promised benefits
The usual arguments in favor of this pattern are:
- We only have to implement the client once, we are following DRY.
- Engineers find it easier to call the service because they don’t have to write their own client.
- Updating clients is easy this way because we just have to bump the library version.
- It ensures we are calling the other service correctly.
I find some of these are false assumptions. And some of these are true, but come with bigger drawbacks than these advantages. Let me go into detail about each of them.
### It is DRY
_Applying too much DRY_
For the uninitiated, DRY stands for Don’t Repeat Yourself. It’s a principle that says you shouldn’t have code implementing the same principle twice, but reuse one implemenation of that code.
It’s true that this way you only have to maintain one client implementation. However, that implementation must also satisfy the requirements of _all_ client services. When your architecture evolves and your clients develop different needs, this means you’ll have to write more complex code that supports all those needs at the same time.
### Ease of use
I think this one is the truest statement of the bunch. It’ll always be easier to install a dependency and call a function than it is to call an HTTP endpoint. But on well-structured and documented APIs, I don’t find the difference to be all that big. I’ll present an alternative later in the article that is _almost_ as easy as using a dependency.
### Easy updating
If anything changes on the server side, you just have to run a single command on the client to update the package responsible for calling the server. This is easy. However, there are two reasons why I think this is not a very strong argument.
Firstly, you still can’t do any breaking changes on the server side, because you cannot update the client and the server at the same time. So you still have to be careful about how you introduce changes to your APIs.
The second is that while this makes it easy to update, it also forces me to accept any and all updates that are introduced to the client, even if my specific service might not benefit from these. If you have a larger number of clients, you will have to make sure that every client’s needs are met by a single implementation. Depending on how diverse your clients are, this might be easy or very hard. In any case, I find it is often underestimated how much simpler a client can be if it is implemented to just specifically support the needs of a single service. Having a client supporting multiple services will inevitably have to be at least a little more abstract.
### Calling services correctly
This argument is a popular one among people that highly value type-safety. They will claim that having a library ensures that the call made from the client matches the interface that is present on the server. However, I think this is not true at all. The only thing it will guarantee is that the client request will match the API of the server at the time that the client was compiled.
Now, you could be forgiven for thinking this is practically the same. But remember that you usually have multiple environments like a staging, demo, production. And those can run different versions of your server, for various reasons. Maybe a deployment failed, maybe you update the demo environment less frequently. No matter the reason, having a shared library will not protect you to deploy a client with a version of the library that does not work with what is deployed on the server side.
If you want to ensure compatibility between client and server, you have to check their interface compatibility before a deployment. The best way to do that in my experience is [contract testing](https://martinfowler.com/bliki/ContractTest.html).
## Disadvantages
Now that we’ve put the advantages into context, I want to highlight the disadvantages I see with the approach of the shared client library. Those are:
- Versioning is difficult
- You are dependent on the technology it is implemented with
- It introduces subtle coupling
### Versioning hell
Depending on how exactly you implement this approach, you can get into quite a bit of versioning hell. If every service has a dedicated library with a client for that service, you have a lot of library versions to check and update regularly. This creates a complex web of dependencies between different services.
You could decrease the impact of this by putting all client implementations inside a single library. But then you have a single point of failure and a massive shared dependency between all services. Also, you might want to publish the client library from the repository of the service that the client talks to, so that client and service change together. But you can’t do that if all the clients are part of a single library.
### Technology dependency
This is the most obvious drawback, but also the one depending most on your circumstances. Naturally, if you implement a client in a specific language, other services can only use that client if they are also written in the same language, or at least the same runtime. And I don’t think I have to convince anyone that maintaining multiple different implementations of these clients in different languages is a bad idea.
This might not be a big issue for you since you write all your frontends and backends in the same language, like is possible with TypeScript. However, how confident are you that it will stay like this forever? That you will never need to write a service in a different language, maybe for performance reasons? Or maybe at some point you want to have an iOS or Android app. Sure, you can write those in TypeScript as well, but if you want an excellent user experience, you’re usually forced to adopt the native stack of the platform instead.
I think there are situations where you can be quite sure you will not need another language, but don’t be overconfident when deciding this. We humans are historically very bad at predicting the future.
### Coupling
_These have been coupled for a long time_
The most important problem with sharing clients between services is that it introduces a subtle coupling between the services. Naturally, we try to reduce coupling between microservices to the absolute minimum. So this is a problem for us. But many engineers fail to see that sharing a library with a client introduces coupling, so let me explain further.
Without a library, the only coupling that exists is that the client depends on the shape of the API of the server. This is not something we can get around, so this is the absolute minimum of coupling we can get away with. Now, if you also introduce a library that includes types/classes for the server’s business entities and logic to translate those entities to HTTP requests, those are now additional things that the client depends on. You might also decide to use the same type/class for the server and the shared client library. But this means that every change to the representation of the business entity also forces a change in the library, which in turn is also forced on the user of the library.
This might not seem very dangerous when you are starting out, but over time, you will make many changes to your services and to the shared libraries. And there will always be a temptation to put something in the shared library because it is the easiest way to solve a problem at that moment. Maybe you need some caching, maybe a translation function for a specific entity, or maybe add a header with logging information. The amount of responsibilities will inevitably increase over time, increasing the coupling further.
Each and every of these responsibilities is a potential source for breakage on every change. And it is a decision that you make for every user of the client, taking agency away from them and potentially not presenting the optimal solution for their usage patterns. The more services use one of those client libraries, the more difficult it is to introduce changes to the library.
I have personal experience with this downside. At one place I worked at, we had a shared client library for a service that used certain small helper libraries to implement the client. One of those helpers had a big breaking change one day and we had to spend quite some time to both update the library and update all the services that used it. And none of those changes had anything to do with the API itself, so it felt like a big waste of time.
## What to do instead?
But then what should we be doing instead? Should we implement a client in every repository where we need to call another service? While I don’t think that this is actually as bad as it sounds, there is also another solution that avoids this while also avoiding the disadvantages we just talked about so thoroughly.
### Enter OpenAPI
Have you ever heard of [OpenAPI](https://www.openapis.org/)? It is a standard for API descriptions. It defines a format for JSON or YAML files that allows you to specify what endpoints exist on an HTTP API, what parameters they accept, what status codes they can return, and so on. Not only that, but it is a wonderful way to document APIs in a way that is both useful for tooling and also for humans, since you can also add descriptions in prose. Nowadays, many APIs publish an OpenAPI specification for their interfaces. For example, here is the [OpenAPI specification for the PokéAPI](https://github.com/PokeAPI/pokeapi/blob/master/openapi.yml).
For example, the endpoint to list Pokémon on the PokéAPI is described like this:
```yaml
/api/v2/pokemon:
get:
operationId: pokemon_list
description: Pokémon are the creatures that inhabit the world of the Pokémon
games. They can be caught using Pokéballs and trained by battling with other
Pokémon. Each Pokémon belongs to a specific species but may take on a variant
which makes it differ from other Pokémon of the same species, such as base
stats, available abilities and typings. See [Bulbapedia](http://bulbapedia.bulbagarden.net/wiki/Pok%C3%A9mon_(species))
for greater detail.

```
The `$ref: "#/components/schemas/PaginatedPokemonSummaryList"` is a reference to another part of the document. You can use those references to avoid repeating the same payload schema several times.
Now OpenAPI is great for documentation, but it also allows you to generate clients automatically that comply with the spec that you present as an input. So if you create good documentation for your API, you also get a client for that API for free.
### How to use it
There are a few things we need to do to take full advantage of this approach. First, we need to agree in our organization that all services will publish OpenAPI specifications for their APIs. The specifications need to be in a place where every engineer can easily get them. In organizations where I can grant at least read-access for all repositories to the engineers, I usually just define a conventional path where the spec should be put in the repository of the service that implements the described API.
Next, we need to make sure that the API is _actually_ describing the interface of the service. Since the spec is just a JSON or YAML file, this does not enforce anything. And it’s really easy to forget updating the spec after you make a change to your API. An easy way to make sure that the API and the spec match is to use some kind of framework that generates the spec from your API code. In Node.js with TypeScript, [Fastify has a plugin](https://github.com/fastify/fastify-swagger) that uses the schema of your routes to also generate an OpenAPI spec.
This works pretty well. But let’s assume your web server or framework of choice does not offer anything like that. Another easy way to achieve this is to leverage your test suite. During the automated tests of the HTTP API, you can just read the OpenAPI spec and check every request and response against the specification, failing the current test if any of them do not match the spec. An easy way to do this in Node.js is [jest-openapi](https://github.com/openapi-library/OpenAPIValidators/tree/master/packages/jest-openapi#readme). If you already have tests for your HTTP API and an OpenAPI spec, then this literally adds one line of code per test. Like this:
```typescript
import jestOpenAPI from "jest-openapi";
// Here you have to load your OpenAPI spec.
jestOpenAPI("openapi/spec.yml");
describe("GET /example/endpoint", () => {
it("should satisfy OpenAPI spec", async () => {
const response = await fetch("http://localhost:3000/api/v2/pokemon");
expect(response.status).toEqual(200);
// This is what checks the response against your OpenAPI spec.
expect(response).toSatisfyApiSpec();
});
});
```
Now that we know that our spec really describes our implemented API, we only need to solve how the client can call the API. As I already said earlier, we can leverage the specification to generate a client in whatever language we want. For that, we just copy the OpenAPI specification file from the service that defines it into the codebase of the service or client that wants to call the API. In TypeScript, my preferred tool is [openapi-typescript](https://openapi-ts.dev/). It really takes advantage of TypeScript’s type system, allows adding middlewares and authentication, and only weighs about 5kb. Generating a client with it is just one line on your terminal:
```bash
npx openapi-typescript ./openapi/spec.yml -o ./openapi/spec.d.ts
```
And using it is similarly simple:
```typescript
import createClient from "openapi-fetch";
import type { paths } from "./openapi/spec";
const client = createClient<paths>({ baseUrl: "http://localhost:3000" });
// The URL is autocompleted here due to the generated types.
// It also enforces any required headers and returns a discriminated union
// of either the error or the success result.
const { data, error } = await client.GET("/api/v2/pokemon", {
headers: { Authorization: "some-token" },
});
```
And now we are ready to do calls, without having introduced any form of shared library. Success!
### Why is this better?
Since I already spent a lot of time explaining the shared library’s disadvantages, you already probably see how we avoid many of them with this approach. But at the risk of repeating myself, let me explain why this is better than sharing a library with a client implementation.
#### Open for any tech stack
The generator we used to get a client implementation is by far not the only one out there. There is pretty much a generator for every major language. So in a polyglot environment, we can easily generate clients for any of our services in seconds. This also allows each team to choose for themselves which tech stack suits their problem best. While I think there is great benefit in keeping tech stacks across teams consistent, there is usually a need for at least some variation. And you might always have that one really critical service that needs to be really performant, making it a great candidate for a rewrite in Rust.
#### No publishing/updating lifecycle
Obviously, if you don’t have any library, you also don’t need to publish or update it. Depending on the amount of libraries, this saves quite a bit of CI/CD work. And even if you can automate large parts of this lifecycle, it’s still there, it still needs to be maintained, and it can still break. Having no code at all will always be easier to maintain.
#### No single source of truth
This might be a bit counter-intuitive, but I really like that there is no single source of truth. Since we copy-paste the OpenAPI specification from the server, each client ends up with their own version of the specification. You could even delete parts of the specification that you’re not using on your client.
Many engineers shudder at the thought of this, because it is a violation of DRY, and they need to maintain all of those duplicated specs manually. But the mistake is assuming that those specs need to be maintained. We should be trying to avoid making breaking changes to our APIs anyway. So unless there is either a breaking change or I need to call a new endpoint, why would I update my local specification if I can do everything I need with it? There is no reason at all to do this.
This creates a situation where every client has their own truth for what the API of the server looks like. They basically only document _their_ assumptions about the API. As long as the server satisfies every client’s assumptions, it doesn’t really matter that they are different. If one client is missing a field of the response in his spec, but the client doesn’t intend to use that field, then we don’t have a problem.
Since this is not a single source of truth, I like to call this a “distributed truth”. And as the name implies, I also think this is a very suitable solution for a distributed system, which is what a microservice architecture is.
## Potential drawbacks
Every solutions has pros and cons, and this one is not an exception. So while I’m convinced this is the better way to do this, I still want to talk a bit about the challenges with this approach.
### You need to create the specs
This one is somewhat obvious, but depending on your organization, it can be challenging to make engineers write documentation. For this approach to succeed, you need to convince your engineers to document their APIs using the OpenAPI standard. And also to document it well and thoroughly. For example, if you only document success responses and not the possible error status codes, this greatly diminishes the value of the specification.
Having said that, getting a client for free is usually a good incentive to write such a spec. And the payoff for good documentation is well worth the effort even when you don’t use it to generate clients from it.
### Only works with REST APIs
OpenAPI is really focused on documenting REST APIs that use JSON or XML. If you use something like GraphQL or gRPC, OpenAPI doesn’t really work for that. So it’s not a solution that you can employ. Having said that, those solutions usually come with their own way of documenting the APIs and generating clients for them. So it’s a better idea anyways to use what they provide.
## Where client libraries work well
I have mostly worked in environments where there is one service per repository. In this case, I find the OpenAPI approach far superior to the shared client library. However, if you have a monorepo where all clients and the server are in the same codebase, this changes things. You can change the client and server in the same commit, and you can proceed to deploy them entirely together. I can see the approach of sharing a client work very well here. Although this technically wouldn’t be a shared client library, because you just import the same code in both client and server without making it a library.
## Conclusion
Now you should have a good overview of the disadvantages of sharing client implementations using a shared library. You should also know how to do it instead by leveraging OpenAPI specifications.
I want to emphasize that this aims specifically at client libraries. I still think there is a place for shared libraries between microservices if those libraries implement true cross-cutting concerns, like logging, monitoring, or caching. You still have to be careful to stay with a general-purpose implementation of these concerns and not introduce specifics of any service in them, but as long as you do that, shared libraries are a great use case for that.
If you really bought into this and want to try it yourself, start by searching for OpenAPI integration for your current HTTP server or framework and your test framework. This is usually a good place to start when you don’t yet have any specs. Then search for some generators for clients in your tech stack. There are usually plenty to choose from. Once you found the tools you want to use, just start adding a spec for a single, simple endpoint and see how it feels.
I hope this was valuable to you and that I could convince you of my perspective on this topic. If not, I’d love to hear from you why you still think shared client libraries are a good solution for this and what your experience with them is. | mmainz |

For example, many API documentation tools offer a playground whereby developers can “Try” how APIs produce responses for a certain input through various endpoints. Some tools automatically generate code samples for various programming languages so that developers can directly plugin the code for their integration efforts. Developers also explore the various documentation related to API endpoints, such as security, path parameters, query parameters, and responses.
## GenAI use cases for API Documentation
Generative AI (GenAI) enhances the developer experience by providing new ways to interact with API documentation. Developers can get code snippets quickly instead of browsing through entire documentation, troubleshoot errors effectively, generate code documentation, and more importantly, annotate custom fields inside API documentation specification files
#### 1. Content Generation
GenAI tools can automatically create documentation for API endpoints since they can understand the code snippets' logic and functionality. This helps developers to build documentation for REST API endpoints quickly and also emerging GraphQL as well. These can be part of the developer’s IDE/SDK stack whereby documentation generation happens quickly.
#### 2. Enhance Consistency and Quality
GenAI can read and adopt the style guides. The style guides can be then incorporated during the documentation creation process thus enhancing consistency and producing high-quality documentation.
### Code snippets
Instead of browsing through the entire API documentation for code snippets, developers can use GenAI-based search engines to get a code snippet quickly by asking the right questions.For example, the GenAI technology is smart enough to convert code from one programming language to another language. Code snippets can be checked for syntax errors and logical errors. Thus, developers feel empowered as they are able to accomplish tasks much faster and more efficiently.
### Troubleshooting
When a developer is faced with some errors and wishes to troubleshoot code, the GenAI chatbot can greatly enhance the developer experience. Just pasting the error output or error logs into the chatbot prompt and asking how to debug this error would produce a response detailing the troubleshooting sequence. The chatbot can guide and also educate developers on best practices. Suppose the chatbot is using any private knowledge utilizing any internal documentation that has reported this issue as a bug. In that case, it can immediately alert developers in the chat interface about the issue. If the developer is logged in, the chatbot can provide more personalized information based on historic chats, such as
- Proactive updates on the issues that the developer has reported
- Provide more personalized responses based on the developer profile and usage patterns
- Provide updates regarding API uptime and other reliability metrics

Mas o que... | 28,078 | 2024-07-16T11:53:27 | https://dev.to/aghastygd/integracao-do-cloudinary-ao-seu-projeto-django-gratuitamente-8pm | cloudstorage, django, tutorial, python | No [tutorial passado](https://dev.to/aghastygd/hospede-seu-site-django-com-arquivos-estaticos-na-vercel-gratuitamente-novo-metodo-339p), você aprendeu a hospedar um site Django de maneira gratuita no Vercel. Mas o que acontece se o seu site precisar fazer upload de arquivos, como fotos ou vídeos? Normalmente, você teria um diretório de mídia no seu projeto para armazenar e renderizar esses arquivos, pois não é uma boa prática armazenar fotos ou vídeos diretamente no banco de dados.
No entanto, a Vercel não permite escrita na plataforma. Como resolver isso? É aí que entra o Cloudinary, um serviço de upload de imagens e vídeos com um plano gratuito oferecendo 25 GB de storage, ideal para o seu projeto que necessita de armazenamento de mídias.
Neste tutorial, você aprenderá a integrar o Cloudinary ao seu projeto Django, aproveitando a SDK que esta plataforma oferece para Python.
## Implementando Cloudinary no seu projeto Django
Para seguir com esse tutorial, basta ter um projeto Django funcionando, seja ele já hospedado na Vercel ou não, pois o método é o mesmo.
####**Passo 1:**
A primeira coisa é instalar a SDK do Cloudinary no seu ambiente de desenvolvimento usando:
```bash
pip install cloudinary
```
**Dica:** Se for na Vercel, basta adicionar `cloudinary` no `requirements.txt` do seu projeto e fazer o build (redeploy) novamente. Caso esteja controlando versões com o Git, o commit dessa alteração já vai automaticamente buildar na plataforma Vercel e estará instalando a biblioteca usando o nosso [script bash](https://dev.to/aghastygd/hospede-seu-site-django-com-arquivos-estaticos-na-vercel-gratuitamente-novo-metodo-339p#:~:text=mais%20um%20arquivo-,build.sh,-com%20o%20seguinte) que criamos anteriormente.
####**Passo 2:**
No seu `settings.py`, importe o `cloudinary` e adicione a seguinte configuração:
```python
import cloudinary
import cloudinary.uploader
import cloudinary.api
cloudinary.config(
cloud_name = os.getenv("CLOUD_NAME"),
api_key = os.getenv("CLOUD_API_KEY"),
api_secret = os.getenv("CLOUD_SECRET_KEY"),
)
```
####**Passo 3:**
No seu `models.py` faça o seguinte import:
```python
from cloudinary.models import CloudinaryField
```
E no campo de imagem em qualquer modelo seu que faz upload de imagens, use o `CloudinaryField` além de `models.ImageField` (padrão do Django), veja o exemplo de um modelo `Post`:
```python
# models.py
class Post(models.Model):
title = models.CharField(max_length=100)
description = models.CharField(max_length=250)
image = CloudinaryField("image") # nesta linha
def __str__(self):
return self.title
```
####**Passo 4:**
Agora você vai configurar váriaveis de ambiente que chamaste no segundo passo.
Para isso, crie um arquivo `.env` no diretório raíz do seu projeto com as seguintes variáveis:
```makefile
CLOUD_NAME=seu cloud_name
CLOUD_API_KEY=sua api_key
CLOUD_SECRET_KEY=sua secret_key
```
**Dica:** Se estiver usando a Vercel, você pode adicionar variáveis de ambiente diretamente nas configurações do projeto na dashboard da plataforma. Além de criar um arquivo `.env` localmente, acesse a dashboard da Vercel e adicione as variáveis com os respectivos valores no seu projeto.
Falando em valores, você precisará pegar eles na sua conta do Cloudinary, para isso, acesse o [site oficial](https://cloudinary.com/), e crie uma conta se não tiver uma.
Tendo acesso à Dashboard da sua conta, clique em **"Go to API Key"**:
Na próxima tela, clique em **"Generate API KEY"** para obter suas chaves de acesso:
Com isso, você terá os valores necessários para preencher seu arquivo `.env`: `CLOUD_NAME`, `CLOUD_API_KEY` e `CLOUD_SECRET_KEY`.
Neste tutorial, estamos usando o `os.getenv` para acessar as váriaveis, e para funcionar, precisamos da biblioteca `python-dotenv`. Então, caso não tenha essa biblioteca no seu ambiente, faça a instalação com:
```
pip install python-dotenv
```
E no princípio do `settings.py` do seu projeto, faça a importação dela para permitir o uso:
```python
# settings.py
import os
from dotenv import load_dotenv
load_dotenv()
```
Tudo pronto! Você configurou o Cloudinary no seu projeto, permitindo o upload e host de imagens diretamente na plataforma. Parabéns por ter concluído!
Agora, para exibir essas imagens no seu projeto, você pode configurar suas views e templates para renderizar as URLs das imagens em suas páginas.
##Links Utéis:
- **Projeto usado para configuração de Cloudinary nesse tutorial:** https://github.com/AghastyGD/django-cloudinary-demo.git - Inclusive, neste repositório adicionei `views` e `templates` de exemplo para demonstrar uma imagem hospedada no Cloudinary. Você pode usá-lo como referência.
- **Documentação do Cloudinary para uso com Python:** https://cloudinary.com/documentation/django_integration - Recomendo a leitura, pois oferece diversas funcionalidades adicionais, como compressão de imagens, transformações e muito mais.
Se precisar de mais ajuda ou tiver dúvidas, deixe um comentário. Te vejo na próxima vez 👋.

MILF. Mom, I’d Like to. .. We’ll let you fill in the blank. We recognize them, we appreciate them, and we desire to have one. To anyone who may not know what MILF stands for, it means older women who have a sexual appeal. These hot moms often attract men who are relatively younger than them, as well as teenage boys. You were still young when you saw the original MILF, Stifler’s mom in American Pie.
If there’s anything we’re sure of, all the movies and shows that showed how easy it is to have a MILF was all BS. Being interested in mature women is one thing, but being mature is a whole different thing. Emotional baggage, compatibility issues, complication, do we need to go on?
That’s why we’re bringing you the word of [AI MILF Porn](https://www.kupid.ai/tag/milf). These lovely ladies do not ask for much. They are just here for you and your pleasure. Come, let's explore the good, the naughty, the sexy AI MILF.
**What is AI MILF**
People have different tastes when it comes to selecting their dream girls. Some want innocent 20 years old, others want 30-year-old women, while many crave more experienced women or MILF. We know that all men are wired differently and can be interested in women of different ages and size. To fulfill those desires, we offer you AI-created females for all the types of women you may want.
Lately, one of our most popular categories has become the AI MILF porn. And why not? They are created with a blend of the rawness of real women with cutting-edge technology. These AI-generated women are programmed to talk, dress, and even think like actual women and, at times, even surpass them. And you can select them based on your choice.
This fusion offers a unique experience that traditional adult content cannot provide.
**The Rise of AI MILF Porn**
A study of nearly 9,000 households over 13 years evaluated the marital satisfaction of differently aged couples: “Marital happiness appears to be higher for older women married to younger men than for younger women married to older men.” Ah, so there is something to it, then. Again, it’s science.
**Communication:** Love, as we know, is the basis of every good relationship, and chemistry can be said to be the foundation of love. Nevertheless, chemistry is out of the question if there are no good communication skills. Hence, personality types are used in the process of tailoring the Milf AI Girlfriend that you have.
**Customization:** Creating an A Girlfriend is fun, but AI MILFs don’t solely depend on that. When it comes to the web app, AI Porn plays a huge role in making it even more interesting. You can create images of your AI Girl in the Doggystyle or Cowgirl position. Create whatever comes to your mind and be able to select from a number of various pornographic encounters.
**Flexibility:** Free your imaginations by using AI MILFs.These ladies know no limit they can be as wild as you want. They are always ready to cater any specific fetish that is out there.
**Conclusion**
Now that you know how tempting our AI MILFs are, what are you waiting for? Find a reliable platform like Kupid.ai that lets you create your dream girl exactly how you want. Let the adventure begin!

1,925,438 | Testcontainers + Golang: Melhorando seus testes com Docker | No desenvolvimento de software, testar aplicativos que dependem de serviços externos, como bancos de... | 0 | 2024-07-17T00:53:47 | https://dev.to/rflpazini/testcontainers-golang-melhorando-seus-testes-com-docker-2hb7 | docker, go, testing, coding | No desenvolvimento de software, testar aplicativos que dependem de serviços externos, como bancos de dados, pode ser desafiador. Garantir que o ambiente de teste esteja configurado corretamente e que os testes sejam isolados e reproduzíveis é crucial para a qualidade do software.
Neste artigo, vamos explorar como usar [Testcontainers](https://testcontainers.com/) com Golang para melhorar a produtividade e a qualidade dos testes de integração, garantindo um ambiente de teste consistente e isolado.
## O que é Testcontainers?
Testcontainers é uma biblioteca que facilita a criação e o gerenciamento de contêineres Docker diretamente a partir dos seus testes de código. Originalmente desenvolvida para Java, agora possui implementações para outras linguagens, incluindo [Golang](https://golang.testcontainers.org/quickstart/).
A principal vantagem do Testcontainers é fornecer um ambiente de teste isolado e consistente, eliminando as variáveis e inconsistências que podem ocorrer em testes que dependem de serviços externos.
## Como o Testcontainers Funciona?
Testcontainers usa a API Docker para criar, configurar e gerenciar contêineres. De uma forma resumida, aqui estão os passos básicos de como ele funciona:
- **Criação do Contêiner**: O Testcontainers inicia um contêiner com base em uma imagem Docker especificada. Ele pode ser configurado para usar qualquer imagem disponível no Docker Hub ou em repositórios privados.
- **Configuração**: Você pode configurar o contêiner para atender às necessidades específicas do seu teste. Isso inclui definir variáveis de ambiente, montar volumes e configurar portas.
- **Esperas e Estratégias de Inicialização**: O Testcontainers fornece estratégias para esperar que o contêiner esteja pronto antes de executar os testes. Por exemplo, você pode esperar até que uma determinada porta esteja aberta ou até que um log específico apareça.
- **Conexão**: Uma vez que o contêiner está em execução e configurado, o Testcontainers fornece os detalhes de conexão (como URL de conexão do banco de dados) que podem ser usados nos testes.
- **Limpeza**: Após a execução dos testes, o Testcontainers garante que os contêineres sejam interrompidos e removidos, mantendo o ambiente de desenvolvimento limpo.
Essa abordagem garante que cada teste seja executado em um ambiente isolado, evitando interferências e garantindo reprodutibilidade.
## Por que usar Testcontainers?
Testcontainers oferece várias vantagens para testes de integração, entre elas:
- **Isolamento**: Cada teste é executado em um ambiente isolado, eliminando interferências entre testes.
- **Consistência**: Garantia de que o ambiente de teste é sempre o mesmo, independentemente de onde ou quando o teste é executado.
- **Facilidade de Configuração**: Automatiza a configuração do ambiente de teste, incluindo a inicialização e limpeza de contêineres Docker.
- **Reprodutibilidade**: Facilita a reprodução de bugs em um ambiente controlado e previsível.
## Case Real de uso
Toda essa teoria é muito legal, mas chegou a hora de aplicá-la na vida real. Para isso deixei um CRUD bem simples de uma loja de livros e será nosso exemplo de como podemos implementar um teste de integração e testar todo o caminho de nossa API.
> Link do repositório da [book-store](https://github.com/rflpazini/articles/tree/main/book-store)
Essa é a estrutura do nosso projeto:
```bash
book-store/
├── cmd/
│ └── bookstore/
│ └── main.go
├── internal/
│ ├── book/
│ │ ├── model.go
│ │ ├── repository.go
│ │ └── service.go
│ └── server/
│ └── server.go
├── pkg/
│ ├── api/
│ │ └── book/
│ │ └── handler.go //arquivo que iremos testar
│ ├── database/
│ │ └── postgres.go
│ └── utils/
│ └── response.go
└── go.mod
└── go.sum
```
## Implementação dos Testes de Integração
Vamos criar testes de integração para os handlers no pacote book. Usaremos o [Postgres module](https://golang.testcontainers.org/modules/postgres/) para configurar um contêiner PostgreSQL para os testes.
> Podemos utilizar qualquer contêiner que quisermos. Caso não exista uma implementação para um module específico para seu caso, basta utilizar o [GenericContainer](https://golang.testcontainers.org/features/creating_container/)
### Configuração do Contêiner e implementando os testes
A primeira coisa que iremos fazer é criar um arquivo de teste `handler_test.go` dentro do pacote `pkg/api/book`.
Uma de nossas principais funções será a
`setupTestContainer`. Ela configura e inicializa um contêiner PostgreSQL para testes de integração, retorna um pool de conexão do PostgreSQL e uma função de `teardown` para limpar o ambiente de teste após a execução dos testes.
```go
// pkg/api/book/handler_test.go
package book
import (
"context"
"testing"
"github.com/jackc/pgx/v4/pgxpool"
"github.com/testcontainers/testcontainers-go/modules/postgres"
)
const (
dbName = "bookstore"
dbUser = "user"
dbPass = "S3cret"
)
func setupTestContainer(t *testing.T) (*pgxpool.Pool, func()) {
ctx := context.Background()
// Configura o contêiner com a imagem Docker da versão que queremos utilizar,
// nome do banco de dados, usuário e senha, e o driver de comunicação.
postgresC, err := postgres.Run(
ctx,
"postgres:16-alpine",
postgres.WithDatabase(dbName),
postgres.WithUsername(dbUser),
postgres.WithPassword(dbPass),
postgres.BasicWaitStrategies(),
postgres.WithSQLDriver("pgx"),
)
if err != nil {
t.Fatal(err)
}
// Obtém a URI de conexão diretamente do contêiner criado.
dbURI, err := postgresC.ConnectionString(ctx)
if err != nil {
t.Fatal(err)
}
// Cria a conexão utilizando o driver PGX.
db, err := pgxpool.Connect(ctx, dbURI)
if err != nil {
t.Fatal(err)
}
// Cria a tabela "books" no banco de dados.
_, err = db.Exec(ctx, `
CREATE TABLE books (
id SERIAL PRIMARY KEY,
title VARCHAR(255) NOT NULL,
author VARCHAR(255) NOT NULL,
isbn VARCHAR(20) NOT NULL
);
`)
if err != nil {
t.Fatal(err)
}
teardown := func() {
db.Close()
if err := postgresC.Terminate(ctx); err != nil {
t.Fatalf("failed to terminate container: %s", err)
}
}
return db, teardown
}
```
## Escrevendo os cenários de teste
Agora que temos uma função que cria o contêiner, é hora de escrever os cenários de teste. Neste caso utilizaremos os seguintes cenários:
1. Create and Get Book: que irá adicionar um novo livro e retornar em nossa API
2. Update Book: atualizará as informações do livro do DB
3. Delete Book: apagará as informações do nosso livro
### Estrutura dos Testes
Para facilitar a leitura e ser mais fácil a manutenção de nosso teste, vou utilizar um modelo de escrita que se chama [Table Driven Tests](https://go.dev/wiki/TableDrivenTests), onde cada teste é definido por um struct que contém:
- `name`: Nome do teste.
- `method`: Método HTTP a ser usado (GET, POST, PUT, DELETE).
- `url`: URL do endpoint a ser testado.
- `body`: Corpo da requisição.
- `setupFunc`: Função opcional para configurar o estado inicial do banco de dados.
- `assertFunc`: Função para verificar a resposta do teste.
```go
tests := []struct {
name string
method string
url string
body string
setupFunc func(*testing.T, *pgxpool.Pool)
assertFunc func(*testing.T, *httptest.ResponseRecorder)
}
```
### Execução dos Testes
Para cada caso de teste, a função `t.Run` é usada para executar o teste. Dentro de cada teste, se houver uma `setupFunc`, ela é chamada para configurar o estado inicial. Em seguida, uma requisição HTTP é criada e enviada ao endpoint apropriado. A função `assertFunc` é então chamada para verificar se a resposta está correta.
E agora basta adicionar os nós do struct com os cenários de teste que queremos. A função de testes ficará assim:
```go
package book
import (
"context"
"encoding/json"
"net/http"
"net/http/httptest"
"strconv"
"strings"
"testing"
"book-store/internal/book"
"github.com/jackc/pgx/v4/pgxpool"
"github.com/labstack/echo/v4"
"github.com/stretchr/testify/assert"
"github.com/testcontainers/testcontainers-go/modules/postgres"
)
const (
dbName = "bookstore"
dbUser = "user"
dbPass = "S3cret"
)
func setupTestContainer(t *testing.T) (*pgxpool.Pool, func()) {
ctx := context.Background()
// Configura o contêiner com a imagem Docker da versão que queremos utilizar,
// nome do banco de dados, usuário e senha, e o driver de comunicação.
postgresC, err := postgres.Run(
ctx,
"postgres:16-alpine",
postgres.WithDatabase(dbName),
postgres.WithUsername(dbUser),
postgres.WithPassword(dbPass),
postgres.BasicWaitStrategies(),
postgres.WithSQLDriver("pgx"),
)
if err != nil {
t.Fatal(err)
}
// Obtém a URI de conexão diretamente do contêiner criado.
dbURI, err := postgresC.ConnectionString(ctx)
if err != nil {
t.Fatal(err)
}
// Cria a conexão utilizando o driver PGX.
db, err := pgxpool.Connect(ctx, dbURI)
if err != nil {
t.Fatal(err)
}
// Cria a tabela "books" no banco de dados.
_, err = db.Exec(ctx, `
CREATE TABLE books (
id SERIAL PRIMARY KEY,
title VARCHAR(255) NOT NULL,
author VARCHAR(255) NOT NULL,
isbn VARCHAR(20) NOT NULL
);
`)
if err != nil {
t.Fatal(err)
}
teardown := func() {
db.Close()
if err := postgresC.Terminate(ctx); err != nil {
t.Fatalf("failed to terminate container: %s", err)
}
}
return db, teardown
}
func TestHandlers(t *testing.T) {
db, teardown := setupTestContainer(t)
defer teardown()
e := echo.New()
RegisterRoutes(e, db)
tests := []struct {
name string // Nome do teste
method string // Metodo HTTP que será utilizado
url string // URL da API
body string // Body do request
setupFunc func(*testing.T, *pgxpool.Pool) // Função de configuração do nosso teste
assertFunc func(*testing.T, *httptest.ResponseRecorder) // Função onde faremos os asserts
}{
{

}
for _, tt := range tests {

req := httptest.NewRequest(tt.method, tt.url, strings.NewReader(tt.body))
req.Header.Set(echo.HeaderContentType, echo.MIMEApplicationJSON)
rec := httptest.NewRecorder()
c := e.NewContext(req, rec)
switch tt.method {
case http.MethodPost:
assert.NoError(t, CreateBook(c, book.NewService(book.NewRepository(db))))
case http.MethodPut:

c.SetParamValues("1")
assert.NoError(t, DeleteBook(c, book.NewService(book.NewRepository(db))))
}
tt.assertFunc(t, rec)
})
}
}
```
E depois de implementarmos o teste, basta executá-lo:
> Lembre-se de estar com o Docker rodando neste momento
```shell
$ go test ./pkg/api/book -v
```
O resultado será o seguinte:
```shell

I came across some surprising behaviour recently. One of the defining features of tuples is that they can be considered equal if each member of the tuple in the equivalent position is equal.
So the tuple `[1, 3] ` should be equal to the tuple `[1,3]`, but in Typescript they are not because tuples in Typescript are a way of describing the types of heterogeneous arrays (which normally take a single type for all the elements within them).
Arrays are only equal if they are the same reference and there are no special rules for value equality for them in Javascript, which ultimately what we're writing here.
I'm not sure what a better name for what Typescript [calls tuples](https://www.typescriptlang.org/play/?#example/tuples), maybe typed arrays, but the current name does carry some inconvenient expectations for those of us coming from other languages.

1,925,448 | Introducing Vue 3: Exploring Its New Features with Examples | Vue 3, the latest iteration of the popular JavaScript framework, comes with several exciting features... | 0 | 2024-07-17T07:01:23 | https://dev.to/akshayashet/introducing-vue-3-exploring-its-new-features-with-examples-3p2e | Vue 3, the latest iteration of the popular JavaScript framework, comes with several exciting features and improvements that enhance its capabilities for building modern web applications. In this technical blog post, we'll delve into some of the key features introduced in Vue 3 and provide examples to illustrate their usage.
**1. Composition API:**
Vue 3 introduces the Composition API, which offers a new way to organize and reuse logic across components. Let's take a look at a simple example of using the Composition API to fetch and display data in a Vue 3 component:
```javascript
import { ref, onMounted } from 'vue';
export default {
setup() {
const data = ref([]);
onMounted(async () => {
const response = await fetch('https://api.example.com/data');
data.value = await response.json();
});
return {
data
};
}
};
```
In this example, we use the `ref` function to declare reactive data and the `onMounted` lifecycle hook to fetch data when the component is mounted. This demonstrates how the Composition API allows for more streamlined organization and reuse of component logic.
**2. Teleport:**
The new Teleport feature in Vue 3 allows developers to render a component's children at a different place in the document hierarchy. Let's consider an example of using Teleport to create a modal dialog in Vue 3:
```javascript
<template>
<teleport to="body">
<div v-if="showModal" class="modal">
<h2>Modal Dialog</h2>
<p>This is a modal dialog rendered outside the current DOM hierarchy.</p>
</div>
</teleport>
</template>
<script>
import { ref } from 'vue';
export default {
setup() {
const showModal = ref(false);
return {
showModal
};
}
};
</script>
```
In this example, we use the `teleport` component to render the modal dialog outside the current DOM hierarchy, allowing for greater flexibility in managing the position and behavior of dynamic UI elements.
**3. Fragments:**
Vue 3 introduces support for Fragments, which enable components to return multiple root nodes without the need for an extra wrapping element. Here's an example of using Fragments to render a list of items in a Vue 3 component:
```javascript
<template>
<>
<h2>Item List</h2>
<ul>
<li v-for="item in items" :key="item.id">
{{ item.name }}
</li>
</ul>
</>
</template>
<script>
import { ref } from 'vue';
export default {
setup() {
const items = ref([
{ id: 1, name: 'Item 1' },
{ id: 2, name: 'Item 2' },
{ id: 3, name: 'Item 3' }
]);
return {
items
};
}
};
</script>
```
In this example, we use Fragments to return multiple root nodes from the component without needing to wrap them in a parent element, resulting in cleaner and more concise template code.
**4. Better TypeScript Support:**
Vue 3 offers enhanced support for TypeScript, providing better type inference and more robust type checking capabilities. Here's a simple example demonstrating improved TypeScript support in Vue 3 component:
```typescript
interface User {
id: number;
name: string;
age: number;
}
export default defineComponent({
data(): {
return {
user: {
id: 1,
name: 'John Doe',
age: 30
} as User
};
}
});
```
In this TypeScript example, we define an interface for the `User` type and use it to provide type annotations for the `user` data property, leveraging Vue 3's improved TypeScript integration.
**5. Smaller Bundle Size and Better Performance:**
Vue 3 has been optimized for improved performance and reduced bundle size, thanks to its re-written virtual DOM implementation. While the benefits of performance optimizations may not be directly demonstrated in a code example, developers can expect faster rendering and better overall application performance in Vue 3.
_In conclusion, Vue 3 introduces a host of compelling new features and improvements that enhance its capabilities for building modern web applications. From the Composition API to Teleport, Fragments, improved TypeScript support, and performance optimizations, Vue 3 offers a powerful set of tools and capabilities for developers. The examples provided here illustrate the practical usage of these features, showcasing their utility and flexibility in real-world Vue 3 applications._ | akshayashet | |

1,925,450 | Solving the SQL Murder Mystery: A Step-by-Step Guide | Maybe I should consider a career as a detective! In this article, I am going to walk you through how... | 0 | 2024-07-16T12:30:03 | https://dev.to/mayorla/solving-the-sql-murder-mystery-a-step-by-step-guide-29cc | sql, database, datascience, howto | Maybe I should consider a career as a detective! In this article, I am going to walk you through how I solved a mystery murder case from SQL Murder Mystery. Let us dive into the crime scene and uncover the truth step by step.
**The Mystery**
A crime has taken place and the detective needs your help. The detective gave you the crime scene report but you somehow lost it. You vaguely remember that the crime was a murder that occurred sometime on Jan. 15, 2018, and that it took place in SQL City. Let's start by retrieving the corresponding crime scene report from the police department’s database. A schema was provided;
**The Initial Clues**
I only remembered the type of crime, the city, and the date. So, I started with this query:
```
SELECT * FROM crime_scene_report
WHERE type = 'murder'
AND city = 'SQL City'
AND date = '20180115';
```
Here’s what I found:
"Security footage shows that there were 2 witnesses. The first witness lives at the last house on "Northwestern Dr". The second witness named Annabel lives somewhere on "Franklin Ave""
Great! So We have two witnesses. The first one lives at the last house on Northwestern Dr, and the second one, Annabel, lives on Franklin Ave.
**Finding the First Witness**
To identify the first witness, I run this query:
```
SELECT * FROM person
WHERE address_street_name = 'Northwestern Dr'
ORDER BY address_number DESC
LIMIT 1;
```
From this query, I was able to identify **Morty Schapiro** with person_id 14887 and license_id 118009 as my first witness.
**Finding the Second Witness**
For the second witness, Annabel, I ran:
```
SELECT * FROM person
WHERE name LIKE 'Annabel%'
AND address_street_name = 'Franklin Ave';
```
From this query, I was able to get my second witness **Annabel Miller** with person_id 16371 and license_id 490173.
**Gathering Witness Statements**
Next, I needed to find out what each witness saw. I run a query to know what Morty Schapiro witnessed:
```
SELECT * FROM interview
WHERE person_id = '14887';
```
Morty's statement: I heard a gunshot and then saw a man run out. He had a "Get Fit Now Gym" bag. The membership number on the bag started with "48Z". Only gold members have those bags. The man got into a car with a plate that included "H42W".
Now, let’s run a query to get Annabel Miller's statement:
```
SELECT * FROM interview
WHERE person_id = '16371';
```
Annabel's statement: I saw the murder happen and I recognized the killer from my gym when I was working out last week on January the 9th.
**Identifying the Killer**
From the statements above, I know the following:
- The murderer is a "Get Fit Now Gym" gold member.
- The membership number starts with "48Z".
- The car plate includes "H42W".
- The murderer was at the gym on January 9th.
First, I checked for gym check-ins on January 9th with this query:
```
SELECT * FROM get_fit_now_check_in
WHERE check_in_date = '20180109'
AND membership_id LIKE '48Z%';
```
I got two results with membership_id 48Z7A and 48Z55. Both are gold members, so I need to narrow it down using the car plate information.
Narrowing Down the Suspects
First, I retrieved the license details for both suspects:
```
SELECT * FROM person
WHERE id IN (28819, 67318);
```
I got two result from running the query above: Jeremy Bowers with license_id 423327 and Joe Germuska with license_id 173289.
Next, I checked their car plates:
```
SELECT * FROM drivers_license
WHERE id IN (423327, 173289);
```
From my result, I was able to identify Jeremy Bowers as the Murderer.
**The Real Mastermind**
Upon further investigation, I found that Jeremy Bowers was hired by a woman with distinct characteristics. Let’s run a query to see his statement:
```
SELECT * FROM interview
WHERE person_id = '67318';
```
Jeremy's statement: I was hired by a woman with a lot of money. I don't know her name but I know she's around 5'5" (65") or 5'7" (67"). She has red hair and she drives a Tesla Model S. I know that she attended the SQL Symphony Concert 3 times in December 2017.
Using this information, I searched for the woman:
```
SELECT * FROM drivers_license
WHERE hair_color = 'red'
AND gender = 'female'
AND car_make = 'Tesla'
AND car_model = 'Model S';
```
I got 3 results from this, all with the same height as described by Jeremy. From Jeremy's statement the mastermind attended SQL Symphony Concert thrice.
I run a query to check for the person_id on the person table.
```
SELECT * FROM person
WHERE license_id in (202298,291182,918773);
```
I got the license_id and name of the 3 possible mastermind from the query above; Red korb with id 78881, Regina George with id 90700 and Miranda Priestly with id 99716.
Finally, I run a query to check their attendance at the SQL Symphony Concert, to see who attended thrice;
```
SELECT * FROM facebook_event_checkin
WHERE person_id IN (78881, 90700, 99716);
```
From my query, I was able to get that The mastermind is Miranda Priestly with person_id 99716, who attended the concerts three times.
Conclusion
The murderer is Jeremy Bowers, but the mastermind behind the crime is Miranda Priestly. This was a thrilling case to solve, combining SQL queries with logical deduction. It was an exciting journey to catch the real villain behind the murder.

1,925,456 | Day 1 of NodeJS || Introduction | Hey reader 😊 Excited huh!!😁 From today (16/07/2024) we are going to start our NodeJS series🥳. In... | 0 | 2024-07-16T12:31:36 | https://dev.to/akshat0610/day-1-of-nodejs-introduction-449j | webdev, node, beginners, tutorial | Hey reader 😊 Excited huh!!😁
From today (16/07/2024) we are going to start our NodeJS series🥳. In this series we are going to cover everything. we will start from very basic and will take it to advanced level.
Prerequisites-:
- Basic understanding of JavaScript.
- Understanding of Synchronous and Asynchronous Programming.
You can read above stuff from here👉[https://dev.to/akshat0610/javascript-series-log-3mp7](url)
In this blog I am going to give you an Introduction of NodeJS.
So let's get started 🔥
## What is NodeJs?
Node.js is an **open source** and **cross platfrom** JS runtime environment. It enables us to execute JS code on server side ,handling tasks such as server side scripting ,networking ,file operations etc.
Node.js is a cross platfrom JS runtime environment this means that Node.js can run outside of a web browser , which means we can use JavaScript for server side programming and Node.js is cross platfrom that is it is compatible for different operating systems.
Now we are seeing two words here **Server** and **Web Browsers**, what they actually are🤔. Let's see-:
**Server** -: A server is a computer system or a software system that provides services or resources to other computers or clients over network. They often host websites ,web applications, APIs, databases and other resources. They are responsible for processing requests , executing code and managing data storage and retrieval.
**Browser** -: A browser is a software application used to access and view information on World Wide Web. They interpret and render web pages written in HTML,CSS and JS. Browers send requests to servers to retrieve web pages and other resources.
Node.js runs the **V8 JS engine** , the core of Google Chrome ,outside the browser. The **V8 engine is an open-source JavaScript engine developed by Google** for the Chrome web browser. The V8 engine is written in C++ and is highly optimized for performance. It compiles JavaScript code into machine code directly, rather than interpreting it line by line, which helps to achieve high execution speeds. Node.js leverages the V8 engine to execute JavaScript code outside of the browser, making it fast and efficient for server-side applications.
## History of NodeJS
The history of Node.js is fascinating! It all began in 2009, when Ryan Dahl created the first version of Node.js. He wanted to create a fast and lightweight runtime environment for JavaScript, and he chose to use the Google Chrome V8 JavaScript engine as the foundation for Node.js. The first release of Node.js was met with great enthusiasm by developers, and it quickly gained popularity as a platform for developing server-side applications.
Later in 2011 , npm (Node Package Manager) was introduced, becoming the default package manager for Node.js. npm provided a vast ecosystem of reusable modules and libraries, greatly accelerating the development process for Node.js developers.
In all of these years different versions of Node.js have been introduced and various useful features have been added. The latest version of Node.js is Node v22.0.0 released on 24/04/2024 .
## Advantages of Node.js
- Fast and Scalable: Node.js is built on the V8 JavaScript engine from Google, which compiles JavaScript directly into machine code, resulting in lightning-fast execution. Its event-driven, non-blocking I/O model allows for handling multiple requests simultaneously, making it highly scalable.
- Single Language: With Node.js, you can use JavaScript on both the client and server-side, streamlining development and reducing context-switching between different languages.
- Large Ecosystem: Node.js has a vast ecosystem of libraries and frameworks available via npm (Node Package Manager), the largest ecosystem of open-source libraries in the world. This allows developers to leverage existing solutions for various tasks, reducing development time and effort.
- Asynchronous and Non-blocking: Node.js uses asynchronous, non-blocking I/O operations, allowing it to handle concurrent connections efficiently. This makes it ideal for building real-time applications such as chat apps, gaming platforms, and streaming services.
- Community Support: Node.js has a vibrant and active community of developers, contributors, and enthusiasts who continually improve the platform, provide support, and share knowledge through forums, meetups, and online communities.
- Cross-platform: Node.js is cross-platform, meaning it can run on various operating systems such as Windows, macOS, and Linux. This flexibility allows developers to build applications that can run seamlessly across different environments.
- Microservices Architecture: Node.js is well-suited for microservices architecture, where applications are composed of small, independent services that can be developed, deployed, and scaled independently. Its lightweight nature and efficient handling of I/O make it an excellent choice for building microservices-based applications.
- Real-time Web Applications: Node.js excels at building real-time web applications that require constant communication between the client and server, such as online gaming platforms, collaborative editing tools, and live chat applications.
- Performance Monitoring and Debugging: Node.js comes with built-in tools for performance monitoring and debugging, such as the Node.js Inspector and various profiling tools. These tools make it easier for developers to diagnose and optimize their applications for better performance.
- Enterprise Adoption: Many large enterprises and tech giants such as Netflix, PayPal, LinkedIn, and Uber have adopted Node.js for their backend systems, demonstrating its reliability, scalability, and performance in production environments.
In summary, Node.js offers a potent combination of speed, scalability, flexibility, and a thriving ecosystem, making it an ideal choice for building modern, high-performance web applications.
Note that we shouldn’t use Node.js in CPU intensive applications.
In summary Node.js has made it easy for everyone by providing single language for both frontend and backend. It has made web development way easier.
I hope you have understood what Node.js is and it’s importance .We will see more about it in next articles. Till then stay connected. Don’t forget to follow me 😄.
Thankyou 🤍

By 2024, Single-page Applications (SPAs) will likely outnumber Multi-page Applications (MPAs). An SPA loads a single page initially. It then updates this page with new material as users interact. In contrast to conventional MPAs, which load a new page for each interaction, SPAs dynamically produce content and transition between user inputs with ease.
Motion UI
Consumer attention spans in an era of limitless digital stimulation are just moments long. In an era where people’s attention spans are getting shorter, businesses employ every tactic in the book and yet fail to succeed. They are anticipated to address their primary issue as 2024 approaches with the emergence of Motion UI, which is completely transforming front-end development. Basic definition: Motion UI is a novel method to user interface (UI) design that uses animations and transitions to improve the user experience (UX) of web applications.
JAMStack
In 2024, JAMStack appears to be really here, expanding the possibilities for front-end programming. In JAMStack, JAM stands for JavaScript, APIs, and mark-up (HTML and CSS). Taken together, these components form a modular web development architecture that includes higher-level markup data that has already been precompiled and is stored and served through content delivery networks (CDNs). Additionally, the dynamic features of JavaScript and APIs are added to the mix.
Micro Front-Ends
By 2024, micro front ends will have grown to prominence and be influencing front end development techniques. Micro Front-Ends, which have their own codebase, development team, and deployment pipelines, divide huge, complicated Front-End systems into smaller, lightweight, and manageable portions in contrast to monolithic designs. These components, also known as micro Front-Ends, operate independently, reflecting the principles of microservices architectures and enabling developers to handle various components without interfering with the main architectural layer.
VR and AR
The two common sectors have advanced significantly. However, new technologies will push the frontiers even further in 2024. By projecting digital objects onto a live view or replacing a real-life environment with a simulated one, VR and AR technologies are enhancing the immersion and interactivity of web apps. This will ultimately lead to greater business growth and enhanced conversions. With improvements in both hardware and software, the technologies are getting a big push and are going to change the way users interact with them.

If you like these kinds of analysis, you should subscribe to the [AImodels.fyi newsletter](https://aimodels.substack.com) or follow me on [Twitter](https://twitter.com/mikeyoung44).*
## Overview
- This paper introduces "SpreadsheetLLM," a novel approach for encoding spreadsheets to enable their use with large language models (LLMs).
- The researchers propose techniques to represent the structure, formulas, and data of spreadsheets in a format that can be effectively processed by LLMs.
- Experiments demonstrate that SpreadsheetLLM outperforms previous methods for spreadsheet-related tasks like formula prediction and cell value generation.
## Plain English Explanation
Spreadsheets are a commonly used tool for organizing and analyzing data, but they can be challenging for large language models (LLMs) to understand. [This paper](https://aimodels.fyi/papers/arxiv/spreadsheetbench-towards-challenging-real-world-spreadsheet-manipulation) introduces a new way to represent spreadsheets that makes it easier for LLMs to work with them.
The key idea is to encode the structure, formulas, and data in spreadsheets in a format that LLMs can process more effectively. For example, the researchers represent the relationships between cells and the logic encoded in formulas in a way that preserves the spreadsheet's semantics. [This allows LLMs](https://aimodels.fyi/papers/arxiv/large-language-modelsllms-tabular-data-prediction-generation) to better understand and reason about the contents of a spreadsheet.
By using this SpreadsheetLLM approach, the researchers show that LLMs can perform tasks like predicting missing cell values or generating new formulas [more accurately](https://aimodels.fyi/papers/arxiv/unleashing-potential-large-language-models-predictive-tabular) than previous methods. This could be useful for applications like spreadsheet automation, where an LLM could assist users by suggesting relevant formulas or completing partially filled-in spreadsheets.
## Technical Explanation
The paper introduces "SpreadsheetLLM," a novel encoding scheme that represents spreadsheets in a format suitable for processing by large language models (LLMs). The key elements of the SpreadsheetLLM approach are:
1. **Structural Encoding**: The researchers develop a way to encode the hierarchical structure of a spreadsheet, including the relationships between cells, sheets, and workbooks. This preserves the semantic meaning of the spreadsheet layout.
2. **Formula Encoding**: Spreadsheet formulas are encoded using a domain-specific language that captures the logic and dependencies between cells. This allows LLMs to understand and reason about the computational aspects of the spreadsheet.
3. **Data Encoding**: The numerical and textual data within the spreadsheet cells are encoded in a format that can be effectively processed by LLMs, such as using embeddings to represent different data types.
The researchers evaluate SpreadsheetLLM on a range of spreadsheet-related tasks, including [formula prediction](https://aimodels.fyi/papers/arxiv/vision-language-models-spreadsheet-understanding-challenges-opportunities) and cell value generation. They show that SpreadsheetLLM outperforms previous methods that used less structured representations of spreadsheets. This suggests that the proposed encoding scheme enables LLMs to better understand and reason about the content and logic of spreadsheets.
## Critical Analysis
The paper presents a compelling approach for encoding spreadsheets in a way that is compatible with large language models. However, there are a few potential limitations and areas for further research:
1. **Scalability**: While the encoding scheme is designed to be efficient, it's unclear how well SpreadsheetLLM would scale to very large or complex spreadsheets. [Exploring ways to further optimize the encoding](https://aimodels.fyi/papers/arxiv/reallm-general-framework-llm-compression-fine-tuning) could be an area for future work.
2. **Real-world Evaluation**: The paper evaluates SpreadsheetLLM on synthetic datasets and specific tasks. Assessing its performance on more diverse, real-world spreadsheets and a broader range of applications would help validate the approach's practical utility.
3. **Interpretability**: As with many LLM-based systems, it may be challenging to interpret the reasoning behind SpreadsheetLLM's outputs. Developing more transparent and explainable models could be valuable for certain use cases.
Overall, the SpreadsheetLLM approach represents an important step forward in enabling large language models to effectively process and reason about spreadsheet data. Further research and real-world testing could help unlock the full potential of this technology.
## Conclusion
This paper introduces SpreadsheetLLM, a novel encoding scheme that allows large language models to efficiently process and reason about the structure, formulas, and data in spreadsheets. By preserving the semantic information of spreadsheets, the researchers demonstrate that LLMs can outperform previous methods on tasks like formula prediction and cell value generation.
The SpreadsheetLLM approach could have significant implications for the future of spreadsheet automation and other applications where language models need to understand and manipulate tabular data. While the paper identifies some areas for further research, the overall findings suggest that this is a promising direction for bridging the gap between large language models and the practical world of spreadsheets.

If you like these kinds of analysis, you should subscribe to the [AImodels.fyi newsletter](https://aimodels.substack.com) or follow me on [Twitter](https://twitter.com/mikeyoung44).*
## Overview
- This paper examines how large language models (LLMs) can be used to generate and reason about code, but notes that the static nature of these models' knowledge does not reflect the fact that code libraries and APIs are constantly evolving.
- The paper presents a new benchmark called [CodeUpdateArena](https://aimodels.fyi/papers/arxiv/codeeditorbench-evaluating-code-editing-capability-large-language) to test how well LLMs can update their knowledge to handle changes in code APIs.
- The benchmark involves synthetic API function updates paired with program synthesis examples that use the updated functionality, with the goal of testing whether an LLM can solve these examples without being provided the documentation for the updates.
## Plain English Explanation
Large language models (LLMs) are powerful tools that can be used to generate and understand code. However, the knowledge these models have is static - it doesn't change even as the actual code libraries and APIs they rely on are constantly being updated with new features and changes.
[The CodeUpdateArena benchmark](https://aimodels.fyi/papers/arxiv/codeeditorbench-evaluating-code-editing-capability-large-language) is designed to test how well LLMs can update their own knowledge to keep up with these real-world changes. It presents the model with a synthetic update to a code API function, along with a programming task that requires using the updated functionality. The goal is to see if the model can solve the programming task without being explicitly shown the documentation for the API update.
This is a more challenging task than updating an LLM's knowledge about facts encoded in regular text. With code, the model has to correctly reason about the semantics and behavior of the modified function, not just reproduce its syntax. Succeeding at this benchmark would show that an LLM can dynamically adapt its knowledge to handle evolving code APIs, rather than being limited to a fixed set of capabilities.
## Technical Explanation
The paper presents the [CodeUpdateArena benchmark](https://aimodels.fyi/papers/arxiv/codeeditorbench-evaluating-code-editing-capability-large-language) to test how well large language models (LLMs) can update their knowledge about code APIs that are continuously evolving.
The benchmark consists of synthetic API function updates paired with program synthesis examples that use the updated functionality. The goal is to update an LLM so that it can solve these programming tasks without being provided the documentation for the API changes at inference time. This is more challenging than updating an LLM's knowledge about general facts, as the model must reason about the semantics of the modified function rather than just reproducing its syntax.
The dataset is constructed by first prompting GPT-4 to generate atomic and executable function updates across 54 functions from 7 diverse Python packages. Then, for each update, the authors generate program synthesis examples whose solutions are prone to use the updated functionality.
The paper's experiments show that simply prepending documentation of the update to open-source code LLMs like [DeepSeek](https://aimodels.fyi/papers/arxiv/learning-performance-improving-code-edits) and [CodeLlama](https://aimodels.fyi/papers/arxiv/whats-wrong-your-code-generated-by-large) does not allow them to incorporate the changes for problem solving. Furthermore, existing knowledge editing techniques also have substantial room for improvement on this benchmark.
## Critical Analysis
The CodeUpdateArena benchmark represents an important step forward in evaluating the capabilities of large language models (LLMs) to handle evolving code APIs, a critical limitation of current approaches. By focusing on the semantics of code updates rather than just their syntax, the benchmark poses a more challenging and realistic test of an LLM's ability to dynamically adapt its knowledge.
However, the paper acknowledges some potential limitations of the benchmark. For example, the synthetic nature of the API updates may not fully capture the complexities of real-world code library changes. Additionally, the scope of the benchmark is limited to a relatively small set of Python functions, and it remains to be seen how well the findings generalize to larger, more diverse codebases.
Further research is also needed to develop more effective techniques for enabling LLMs to update their knowledge about code APIs. The paper's finding that simply providing documentation is insufficient suggests that more sophisticated approaches, potentially drawing on ideas from [dynamic knowledge verification](https://aimodels.fyi/papers/arxiv/dyknowdynamically-verifying-time-sensitive-factual-knowledge-llms) or [code editing](https://aimodels.fyi/papers/arxiv/learning-performance-improving-code-edits), may be required.
Overall, the CodeUpdateArena benchmark represents an important contribution to the ongoing efforts to [improve the code generation capabilities of large language models](https://aimodels.fyi/papers/arxiv/bigcodebench-benchmarking-code-generation-diverse-function-calls) and make them more robust to the evolving nature of software development.
## Conclusion
This paper presents a new benchmark called CodeUpdateArena to evaluate how well large language models (LLMs) can update their knowledge about evolving code APIs, a critical limitation of current approaches. The benchmark involves synthetic API function updates paired with programming tasks that require using the updated functionality, challenging the model to reason about the semantic changes rather than just reproducing syntax.
The paper's experiments show that existing techniques, such as simply providing documentation, are not sufficient for enabling LLMs to incorporate these changes for problem solving. This highlights the need for more advanced knowledge editing methods that can dynamically update an LLM's understanding of code APIs.
The CodeUpdateArena benchmark represents an important step forward in assessing the capabilities of LLMs in the code generation domain, and the insights from this research can help drive the development of more robust and adaptable models that can keep pace with the rapidly evolving software landscape.

## Overview
This paper introduces a new dataset and experiments to enhance the coherence of extractive summarization using large language models (LLMs). Extractive summarization is the process of selecting and combining the most important sentences from a document to create a concise summary. The authors argue that current extractive summarization models often produce incoherent summaries, and they aim to address this issue.
## Plain English Explanation
The researchers created a new dataset to train and evaluate extractive summarization models that produce more coherent summaries. Coherence refers to how well the sentences in a summary flow together and make sense as a whole.
The key innovations in this work are:
1. They developed a new dataset called [LAMSUM](https://aimodels.fyi/papers/arxiv/lamsum-novel-framework-extractive-summarization-user-generated) that contains human-written summaries annotated for coherence. This allows them to train and evaluate models on coherence.
2. They conducted experiments using different LLM-based approaches to enhance the coherence of extractive summaries, including fine-tuning models on the LAMSUM dataset.
The goal is to create extractive summarization systems that generate summaries that are not just informative, but also flow logically and read naturally. This could make the summaries more useful for tasks like academic research, news reporting, and other applications where coherence is important.
## Technical Explanation
The authors first constructed the LAMSUM dataset, which consists of article passages and corresponding human-written summaries. The summaries were annotated for coherence using crowdsourcing. This allows the researchers to train and evaluate models on their ability to produce coherent extractive summaries.
They then experimented with different LLM-based approaches to improve coherence in extractive summarization:
1. Fine-tuning large language models like BERT, RoBERTa, and GPT-2 on the LAMSUM dataset to directly optimize for coherence.
2. Using LLMs to rerank candidate extractive summaries based on coherence scores.
3. Incorporating coherence scoring as an additional objective when training extractive summarization models.
The results show that the LLM-based approaches can indeed enhance the coherence of extractive summaries compared to previous methods. The authors provide detailed analysis and ablation studies to understand the key factors driving these improvements.
## Critical Analysis
The paper makes a valuable contribution by introducing the LAMSUM dataset and demonstrating effective ways to leverage LLMs to improve coherence in extractive summarization. However, the authors acknowledge some limitations:
- The LAMSUM dataset is relatively small compared to other summarization benchmarks, so the models may not generalize as well to larger-scale real-world applications.
- The coherence annotations in LAMSUM are subjective and may not fully capture all aspects of summary quality.
- The proposed methods still have room for improvement, as even the best-performing models do not achieve human-level coherence scores on the dataset.
It would also be interesting to see how these coherence-enhanced extractive summaries compare to abstractive summarization approaches in terms of both coherence and overall quality. Further research could explore using the LAMSUM dataset for training more advanced summarization models or combining extractive and abstractive techniques.
## Conclusion
This paper presents an important step towards improving the coherence of extractive summarization using large language models. The new LAMSUM dataset and LLM-based methods offer a promising direction for developing more natural and useful text summarization systems. While there are still some limitations to address, this work demonstrates the value of focusing on summary coherence and provides a strong foundation for future research in this area.

## Overview
- Introduces a novel attention mechanism called "SparQ Attention" that can significantly reduce the bandwidth required for large language model (LLM) inference
- Demonstrates the effectiveness of SparQ Attention on various language tasks, including natural language generation, question answering, and text classification
- Provides insights into the potential for bandwidth-efficient LLM inference, which could enable more accessible and energy-efficient AI applications
## Plain English Explanation
The [SparQ Attention](https://aimodels.fyi/papers/arxiv/efficient-economic-large-language-model-inference-attention) paper presents a new way to make large language models (LLMs) more efficient. LLMs are powerful AI systems that can generate human-like text, answer questions, and perform other language-related tasks. However, running these models can be resource-intensive, requiring a lot of computing power and data transfer.
The researchers behind this paper developed a technique called "SparQ Attention" that can significantly reduce the amount of data needed to run an LLM. The key idea is to selectively transfer only the most important information from the model's attention mechanism, rather than transferring the entire attention matrix. This allows the model to make predictions with much less data, saving on bandwidth and energy consumption.
The paper demonstrates that SparQ Attention can maintain the performance of LLMs while reducing the required bandwidth by up to 90%. This could enable more accessible and energy-efficient AI applications, such as running language models on mobile devices or in low-power settings.
## Technical Explanation
The [SparQ Attention](https://aimodels.fyi/papers/arxiv/efficient-economic-large-language-model-inference-attention) paper proposes a novel attention mechanism called "SparQ Attention" that can significantly reduce the bandwidth required for large language model (LLM) inference.
The core idea of SparQ Attention is to selectively transfer only the most important information from the model's attention mechanism, rather than transferring the entire attention matrix. This is achieved by identifying a smaller set of "salient" attention weights that capture the key dependencies in the input sequence.
The [paper](https://aimodels.fyi/papers/arxiv/efficient-economic-large-language-model-inference-attention) introduces two key components to realize this:
1. **Attention Memory Transfer**: A technique to efficiently transfer the salient attention weights from the model to the client, reducing the overall bandwidth requirements.
2. **SparQ Attention**: A modified attention mechanism that can be seamlessly integrated into existing LLMs to enable bandwidth-efficient inference.
The authors evaluate the effectiveness of SparQ Attention on various language tasks, including natural language generation, question answering, and text classification. They demonstrate that SparQ Attention can maintain the performance of LLMs while reducing the required bandwidth by up to 90%, outperforming alternative [bandwidth-efficient techniques](https://aimodels.fyi/papers/arxiv/self-selected-attention-span-accelerating-large-language, https://aimodels.fyi/papers/arxiv/quickllama-query-aware-inference-acceleration-large-language, https://aimodels.fyi/papers/arxiv/relayattention-efficient-large-language-model-serving-long).
## Critical Analysis
The [SparQ Attention](https://aimodels.fyi/papers/arxiv/efficient-economic-large-language-model-inference-attention) paper presents a promising approach to making large language model (LLM) inference more bandwidth-efficient. By selectively transferring only the most important attention information, the technique can significantly reduce the data requirements while maintaining model performance.
However, the paper does not address the potential impact of this selective attention on the interpretability and explainability of the LLM's decision-making process. Removing certain attention weights could affect the model's ability to provide transparent explanations for its outputs, which is an important consideration for many real-world applications.
Additionally, the paper focuses on a specific set of language tasks and does not explore the generalizability of SparQ Attention to other domains or more complex language models. Further research is needed to understand the broader applicability and limitations of this approach.
It's also worth noting that the paper does not discuss the potential security or privacy implications of bandwidth-efficient LLM inference. As AI systems become more widely deployed, it will be crucial to consider the security and privacy trade-offs of such techniques.
## Conclusion
The [SparQ Attention](https://aimodels.fyi/papers/arxiv/efficient-economic-large-language-model-inference-attention) paper presents an innovative approach to making large language model (LLM) inference more bandwidth-efficient. By selectively transferring only the most important attention information, the SparQ Attention technique can reduce the data requirements by up to 90% while maintaining model performance.
This breakthrough could enable more accessible and energy-efficient AI applications, such as running language models on mobile devices or in low-power settings. The potential for bandwidth-efficient LLM inference could have far-reaching implications for the democratization of AI and the development of more sustainable, environmentally-friendly AI systems.
While the paper raises some critical questions about the interpretability and generalizability of the SparQ Attention approach, it represents an important step forward in the ongoing effort to make large language models more efficient and accessible.

## Overview
- Introduces a new class of reinforcement learning (RL) algorithms called Monte Carlo Forest Search (MCFS) for learning policies in tree-structured Markov Decision Processes (tree MDPs)
- Focuses on problems where policy execution involves traversing an exponential-sized tree, such as proving unsatisfiability of a SAT formula, counting the number of solutions to a satisfiable SAT formula, or finding the optimal solution to a mixed-integer program
- Presents an instantiation of MCFS called Knuth Synthesis, which learns DPLL branching policies for solving the Boolean satisfiability (SAT) problem with the goal of achieving good average-case performance on a given distribution of unsatisfiable instances
## Plain English Explanation
The paper introduces a new approach called [Monte Carlo Forest Search (MCFS)](https://aimodels.fyi/papers/arxiv/layered-staged-monte-carlo-tree-search-smt) for solving complex problems that involve searching through an exponentially large tree of possible solutions. Examples of such problems include proving that a set of logical constraints (a SAT formula) has no solutions, counting the number of solutions to a satisfiable SAT formula, or finding the best solution to a mixed-integer programming problem.
The key idea behind MCFS is to view these tree-structured problems not as finding a single good path through the tree, but rather as finding a small "tree" (or set of solutions) within a larger "forest" of candidate trees. The researchers develop a specific MCFS algorithm called Knuth Synthesis, which learns how to make early decisions in the search process that can dramatically reduce the size of the overall search tree.
Knuth Synthesis does this by leveraging two key insights: First, it uses a clever statistical technique developed by Donald Knuth to estimate the size of the search tree by randomly sampling paths through it, rather than trying to fully explore the entire tree. Second, it focuses its learning on the early decisions in the search process, which have the greatest potential to reduce the overall tree size, rather than trying to learn a policy for the entire tree.
By using these techniques, Knuth Synthesis was able to match or exceed the performance of a strong baseline on several well-known SAT problem distributions, even on instances that were two orders of magnitude more challenging than those tackled in previous reinforcement learning studies.
## Technical Explanation
The paper introduces a new class of reinforcement learning (RL) algorithms called [Monte Carlo Forest Search (MCFS)](https://aimodels.fyi/papers/arxiv/monte-carlo-tree-search-boosts-reasoning-via) for learning policies in tree-structured Markov Decision Processes (tree MDPs). In these problems, policy execution involves traversing an exponential-sized tree, which makes traditional RL approaches prohibitively expensive.
MCFS algorithms can be seen as an extension of [Monte Carlo Tree Search (MCTS)](https://aimodels.fyi/papers/arxiv/monte-carlo-search-algorithms-discovering-monte-carlo) to cases where the goal is not to find a good path (solution) within a tree, but rather to find a small tree within a forest of candidate trees. The researchers instantiate and evaluate their ideas in an algorithm called Knuth Synthesis, an MCFS algorithm that learns DPLL branching policies for solving the Boolean satisfiability (SAT) problem.
Knuth Synthesis addresses the prohibitive costs of policy evaluations in an exponentially-sized tree using two key ideas: First, it estimates tree size by randomly sampling paths and measuring their lengths, drawing on an unbiased approximation technique due to [Knuth (1975)](https://aimodels.fyi/papers/arxiv/proof-number-based-monte-carlo-tree-search). Second, it queries a strong solver at a user-defined depth rather than learning a policy across the whole tree, focusing the policy search on early decisions that offer the greatest potential for reducing tree size.
The researchers show that Knuth Synthesis matched or exceeded the performance of a strong baseline on three well-known SAT distributions, tackling problems that were two orders of magnitude more challenging than those addressed in previous RL studies.
## Critical Analysis
The paper presents a novel and promising approach to solving complex, tree-structured problems using reinforcement learning. The key insights of using statistical tree size estimation and focusing the policy search on early decisions are clever and well-justified.
However, the paper does not provide a comprehensive analysis of the limitations of the Knuth Synthesis algorithm. For example, it would be useful to understand how the performance of the algorithm scales with the size and complexity of the problem instances, or how sensitive it is to the choice of the user-defined depth at which the strong solver is queried.
Additionally, the paper does not compare Knuth Synthesis to other recent advances in RL for tree-structured problems, such as [the work on proof-number based MCTS](https://aimodels.fyi/papers/arxiv/accessing-gpt-4-level-mathematical-olympiad-solutions). Exploring these comparisons could provide valuable insights into the relative strengths and weaknesses of different approaches.
Overall, the paper makes a strong contribution by introducing MCFS and the Knuth Synthesis algorithm, but there is room for further research to fully understand the capabilities and limitations of this new class of RL algorithms.
## Conclusion
This paper presents a novel class of reinforcement learning algorithms called Monte Carlo Forest Search (MCFS) for tackling complex, tree-structured problems. The researchers develop a specific MCFS algorithm called Knuth Synthesis, which learns DPLL branching policies for solving the Boolean satisfiability (SAT) problem.
By leveraging statistical tree size estimation and focusing the policy search on early decisions, Knuth Synthesis was able to match or exceed the performance of a strong baseline on several well-known SAT problem distributions, even on instances that were significantly more challenging than those addressed in previous RL studies.
This work opens up new avenues for applying reinforcement learning to a broader class of problems that involve searching through exponentially large trees of possibilities, with potential applications in areas like theorem proving, program synthesis, and optimization. Further research is needed to fully understand the capabilities and limitations of MCFS algorithms, but this paper represents an important step forward in this promising direction.

## Overview
- This paper presents a novel approach for estimating the number of clusters in a dataset using human input and a similarity-driven nested importance sampling technique.
- The method allows users to interactively guide the clustering process and provide feedback to refine the cluster count estimation.
- The proposed approach aims to address the challenge of determining the optimal number of clusters, which is a common issue in unsupervised learning.
## Plain English Explanation
Clustering is a widely used technique in data analysis to group similar data points together. However, determining the right number of clusters, known as the "cluster count," can be challenging, especially in complex datasets. [This paper introduces a new method](https://aimodels.fyi/papers/arxiv/learning-commonality-divergence-variety-unsupervised-visible-infrared) that combines human input and a statistical sampling technique to estimate the cluster count more effectively.
The key idea is to let the user provide feedback on the clustering results and use that information to refine the estimation process. The method starts by randomly sampling data points and grouping them into an initial set of clusters. The user then reviews these clusters and indicates which ones are similar or dissimilar. This user feedback is used to guide a nested importance sampling algorithm, which iteratively adjusts the cluster count to better match the user's understanding of the data.
By incorporating human expertise into the clustering process, the method can overcome the limitations of purely algorithmic approaches and converge on a cluster count that aligns with the user's intuition about the dataset. [This approach can be particularly useful](https://aimodels.fyi/papers/arxiv/synthesizing-efficient-data-diffusion-models-person-re) when working with large or complex datasets where the optimal number of clusters is not immediately apparent.
## Technical Explanation
The paper proposes a human-in-the-loop approach for estimating the number of clusters in a dataset. The method starts by randomly sampling a subset of data points and performing an initial clustering. The user then reviews the resulting clusters and provides feedback on which ones are similar or dissimilar.
This user feedback is incorporated into a nested importance sampling algorithm, which iteratively adjusts the cluster count to better match the user's understanding of the data. The algorithm uses a similarity-driven sampling strategy to focus on the regions of the data space where the user's feedback indicates the clustering could be improved.
The sampling process involves two nested loops: an outer loop that updates the cluster count and an inner loop that refines the cluster assignments based on the user's feedback. The algorithm continues to refine the cluster count and assignments until the user is satisfied with the results or a predefined stopping criterion is met.
[The authors evaluate the proposed method](https://aimodels.fyi/papers/arxiv/robust-pseudo-label-learning-neighbor-relation-unsupervised) on several synthetic and real-world datasets, demonstrating its ability to converge to the correct cluster count more accurately and efficiently than traditional clustering algorithms. They also show that the method can adapt to the user's preferences and provide insights that may not be captured by purely algorithmic approaches.
## Critical Analysis
The paper presents a promising approach for incorporating human expertise into the clustering process, which can be particularly valuable when working with complex or high-dimensional datasets. By allowing the user to provide feedback and guide the clustering, the method can overcome the limitations of automatic clustering algorithms and converge on a cluster count that better aligns with the user's understanding of the data.
However, the paper does not address the potential biases or subjectivity that may arise from the user's feedback. [It is important to consider how the method would handle disagreements between multiple users](https://aimodels.fyi/papers/arxiv/instruct-reid-towards-universal-purpose-instruction-guided) or how to ensure the feedback is representative of the overall dataset. Additionally, the paper does not explore the scalability of the method to very large datasets or its performance on datasets with complex, non-convex cluster shapes.
[Further research could investigate ways to quantify the reliability and consistency of the user feedback, as well as techniques to handle diverse user preferences or incorporate uncertainty into the cluster count estimation](https://aimodels.fyi/papers/arxiv/addressing-elephant-room-robust-animal-re-identification). Additionally, exploring the integration of this method with other clustering algorithms or visualization techniques could enhance its practical utility and acceptance within the data analysis community.
## Conclusion
The proposed human-in-the-loop approach for estimating the number of clusters in a dataset represents a promising step towards more intuitive and user-friendly clustering methods. By incorporating human expertise and feedback into the clustering process, the method can overcome the limitations of purely algorithmic approaches and converge on a cluster count that better aligns with the user's understanding of the data.
While the paper raises some interesting questions about the potential biases and scalability of the method, it demonstrates the value of leveraging human-computer interaction techniques in the context of unsupervised learning. As the field of data analysis continues to evolve, methods like this one may play an increasingly important role in empowering users to explore and make sense of complex datasets more effectively.

The paper also delves into [Algebraic Topology](https://aimodels.fyi/papers/arxiv/transport-algebraic-structure-to-latent-embeddings), which studies the properties of shapes and spaces that remain unchanged under continuous deformations. By incorporating these topological insights, machine learning models can better handle noisy, high-dimensional, or manifold-structured data.
Additionally, the authors explore the use of [Riemannian Geometry](https://aimodels.fyi/papers/arxiv/singular-riemannian-geometry-approach-to-deep-neural) in machine learning. Riemannian geometry is a powerful framework for studying curved spaces, which can be useful for modeling complex, non-Euclidean data structures that are common in real-world applications.
By bridging the gap between advanced mathematics and practical machine learning, this paper aims to inspire new directions for research and development in the field, leading to more powerful, interpretable, and adaptable AI systems.

## Overview
• The paper introduces **[WildGaussians](https://aimodels.fyi/papers/arxiv/wild-gs-real-time-novel-view-synthesis)**, a novel 3D Gaussian splatting technique for real-time novel view synthesis in uncontrolled scenes.
• The method represents 3D scenes using a sparse set of Gaussian primitives, which can be efficiently rendered using GPU-accelerated splatting.
• This enables high-quality 3D reconstruction and rendering from sparse RGB-D or multi-view data, even in challenging real-world environments.
## Plain English Explanation
The paper presents a new way to create 3D models from images and videos captured in the real world. Traditional 3D modeling often requires carefully controlled environments or expensive equipment. **[WildGaussians](https://aimodels.fyi/papers/arxiv/wild-gs-real-time-novel-view-synthesis)** aims to make 3D modeling more accessible by working with regular photos and videos taken in uncontrolled settings, like a person's home or a busy city street.
The key insight is to represent the 3D world using simple geometric shapes called Gaussians. These Gaussians can be quickly rendered on a computer's graphics card, allowing for real-time 3D reconstruction and rendering. This means you can create 3D models and explore them interactively, even on ordinary devices like smartphones or laptops.
The **[WildGaussians](https://aimodels.fyi/papers/arxiv/wild-gs-real-time-novel-view-synthesis)** approach is inspired by recent advances in **[3D Gaussian splatting](https://aimodels.fyi/papers/arxiv/recent-advances-3d-gaussian-splatting)** and **[generative models](https://aimodels.fyi/papers/arxiv/gaussian-splatting-decoder-3d-aware-generative-adversarial)** that can create 3D scenes from 2D images. By combining these ideas, the researchers have developed a system that can capture the complex shapes and appearances found in real-world environments, while still being efficient enough for interactive use.
## Technical Explanation
The **[WildGaussians](https://aimodels.fyi/papers/arxiv/wild-gs-real-time-novel-view-synthesis)** system first uses a neural network to extract a sparse set of 3D Gaussian primitives from RGB-D or multi-view input data. These Gaussians represent the geometry and appearance of the scene in a compact way.
To render the 3D scene, the system uses GPU-accelerated **[Gaussian splatting](https://aimodels.fyi/papers/arxiv/recent-advances-3d-gaussian-splatting)**. This means that each Gaussian primitive is "splatted" or projected onto the screen, creating a smooth, high-quality 3D reconstruction. The system can also handle **[appearance-conditioned Gaussians](https://aimodels.fyi/papers/arxiv/swag-splatting-wild-images-appearance-conditioned-gaussians)** to capture complex material properties.
The researchers evaluate **[WildGaussians](https://aimodels.fyi/papers/arxiv/wild-gs-real-time-novel-view-synthesis)** on a variety of real-world scenes, demonstrating its ability to handle challenging environments and produce high-fidelity 3D reconstructions at interactive framerates. They also show how the system can be integrated with **[neural radiance fields](https://aimodels.fyi/papers/arxiv/gaussian-splatting-nerf-based-color-opacity)** for advanced rendering capabilities.
## Critical Analysis
The **[WildGaussians](https://aimodels.fyi/papers/arxiv/wild-gs-real-time-novel-view-synthesis)** approach is a promising step towards making 3D modeling and rendering more accessible, but it does have some limitations. The system is still dependent on RGB-D or multi-view input data, which may not be readily available in all scenarios. Additionally, the neural network used to extract the Gaussian primitives may struggle with highly complex or intricate scenes.
Further research could explore ways to make the system more robust to incomplete or noisy input data, or to extend the Gaussian representation to capture even more detailed geometries and appearances. Integrating **[WildGaussians](https://aimodels.fyi/papers/arxiv/wild-gs-real-time-novel-view-synthesis)** with other 3D reconstruction techniques could also lead to interesting synergies and expanded capabilities.
## Conclusion
**[WildGaussians](https://aimodels.fyi/papers/arxiv/wild-gs-real-time-novel-view-synthesis)** represents an important step forward in making 3D modeling and rendering more accessible to a wider audience. By using a sparse Gaussian representation and efficient GPU-accelerated splatting, the system can produce high-quality 3D reconstructions from real-world data in real-time. This could have significant implications for a variety of applications, from virtual and augmented reality to 3D content creation and scene understanding.

## Overview
- Presents a new approach called TurboTLS to establish TLS connections using one less round trip
- Sends the initial client-to-server and server-to-client flows of the TLS handshake over UDP instead of TCP
- Simultaneously carries out the three-way TCP handshake in the same flights
- Completes the final flight of the TLS handshake over the established TCP connection
- Avoids UDP fragmentation issues using request-based fragmentation
- Offers substantial latency improvements, especially on reliable connections
## Plain English Explanation
The paper introduces a new technique called **TurboTLS** that can [establish TLS connections](https://aimodels.fyi/papers/arxiv/case-transport-level-encryption-datacenter-networks) more efficiently by reducing the number of round trips required. Typically, establishing a secure TLS connection involves a back-and-forth exchange between the client and server over a TCP connection.
In the TurboTLS approach, the initial steps of this TLS handshake are sent over a [UDP](https://aimodels.fyi/papers/arxiv/to-switch-or-not-to-switch-to) connection instead of TCP. At the same time, the three-way TCP handshake to set up the underlying connection is also happening. Once the TCP connection is ready, the final step of the TLS handshake can be completed over that TCP link, and then the application data can be sent.
This allows the TLS connection to be established more quickly, effectively **eliminating one round trip** compared to the traditional approach. To avoid issues with UDP packet fragmentation, the system uses a clever technique where the client sends enough initial UDP requests to give the server enough space to fit its full response in a single packet.
Experiments show that this **TurboTLS** approach can provide substantial latency improvements, especially on reliable network connections where the round trip time savings are most impactful. Even on less reliable networks, the system has mechanisms to quickly fall back to the standard TCP-based TLS handshake if needed, ensuring adequate performance.
## Technical Explanation
The core innovation in this paper is the **TurboTLS** technique, which modifies the standard TLS handshake process to leverage [UDP](https://aimodels.fyi/papers/arxiv/core-quic-enabling-dynamic-implementation-agnostic-protocol) in addition to TCP.
Traditionally, the TLS handshake occurs over a TCP connection, requiring multiple round trips between the client and server. In the TurboTLS approach, the initial client-to-server and server-to-client flows of the TLS handshake are sent over UDP rather than TCP. Simultaneously, the three-way TCP handshake to establish the underlying connection is also carried out in these same message flights.
Once the TCP connection is established, the client and server can complete the final flight of the TLS handshake over the TCP link and then use that connection for application data transfer. No changes are made to the contents of the TLS handshake protocol itself - only the delivery mechanism is modified.
To address potential issues with UDP packet fragmentation, the authors employ a **request-based fragmentation** technique. The client sends a series of UDP requests in advance, providing enough space for the server to fit its full response within a single response packet per request packet.
The authors also describe how clients can detect server support for TurboTLS without an additional round trip, by having the server advertise its capabilities in a DNS HTTPS resource record.
Experimental results demonstrate that TurboTLS can provide substantial **latency improvements**, especially on reliable network connections where the round trip time savings are most impactful. To ensure adequate performance on less reliable connections, the system employs lightweight packet ordering and buffering mechanisms, allowing the client to quickly fall back to the standard TCP-based TLS handshake if needed.
## Critical Analysis
The TurboTLS approach presented in this paper offers a novel and promising solution for reducing the latency associated with establishing secure TLS connections. By leveraging UDP in addition to TCP, the authors are able to effectively eliminate one round trip from the standard TLS handshake process.
One key strength of this approach is its **compatibility** with existing TLS infrastructure - the paper does not require any changes to the TLS protocol itself, only the delivery mechanism. This should make it easier to adopt and deploy TurboTLS in real-world environments.
The authors also demonstrate thoughtful solutions to potential challenges, such as the UDP fragmentation issue. The request-based fragmentation technique seems well-designed to address this problem without adding significant complexity.
That said, the paper does not extensively explore the **security implications** of using UDP for the initial TLS handshake flows. While the authors note that no changes are made to the TLS protocol, it would be valuable to have a more thorough security analysis to understand any potential vulnerabilities or attack vectors introduced by this approach.
Additionally, the paper focuses primarily on **latency improvements**, but does not delve deeply into other performance metrics like throughput or CPU/memory usage. Further research could investigate the broader performance characteristics of TurboTLS to fully understand its tradeoffs and limitations.
Overall, the TurboTLS technique presented in this paper represents a promising step forward in optimizing TLS connection establishment. The authors have identified an important problem and developed an innovative solution. However, as with any new approach, ongoing research and real-world deployment will be necessary to fully evaluate its strengths, weaknesses, and long-term viability.
## Conclusion
This paper introduces a novel technique called **TurboTLS** that can establish secure TLS connections using one less round trip than the traditional approach. By sending the initial TLS handshake flows over UDP while simultaneously setting up the underlying TCP connection, TurboTLS is able to reduce the latency of the connection establishment process.
The authors' experimental results demonstrate substantial performance improvements, especially on reliable network connections. The use of request-based fragmentation and other mechanisms to address potential UDP-related issues further bolsters the practicality of this approach.
While the paper does not explore all aspects of TurboTLS's performance and security implications in depth, it presents a compelling and innovative solution to an important problem in network communications. As [web protocols continue to evolve](https://aimodels.fyi/papers/arxiv/session-types-transport-layer-towards-implementation-tcp) and the demand for low-latency, secure connections grows, techniques like TurboTLS may play an increasingly important role in optimizing the underlying infrastructure.

## Overview
- The paper explores the integration of softmax and linear attention mechanisms in transformer models, aiming to improve performance and efficiency.
- It introduces a novel attention module called Agent Attention, which combines the strengths of softmax and linear attention.
- The authors evaluate Agent Attention on various tasks, including image recognition, object detection, and language modeling, demonstrating its advantages over traditional attention mechanisms.
## Plain English Explanation
Attention mechanisms are a crucial component of transformer models, which have revolutionized many areas of artificial intelligence, from [natural language processing](https://aimodels.fyi/papers/arxiv/attention-as-rnn) to computer vision. Transformer models use attention to focus on the most relevant parts of their input when generating output.
The paper explores a new way of doing attention called "Agent Attention," which combines two common attention approaches: [softmax attention](https://aimodels.fyi/papers/arxiv/softmax-attention-constant-cost-per-token) and [linear attention](https://aimodels.fyi/papers/arxiv/breaking-attention-bottleneck). Softmax attention assigns importance to each input element based on its similarity to the current output, while linear attention assigns importance based on a linear transformation of the input.
The key insight of Agent Attention is that by integrating these two approaches, the model can capture both local and global dependencies in the data, leading to improved performance and efficiency. This is particularly useful for tasks like image recognition and object detection, where [Mansformer](https://aimodels.fyi/papers/arxiv/mansformer-efficient-transformer-mixed-attention-image-deblurring) has shown the benefits of [hardware-aware attention mechanisms](https://aimodels.fyi/papers/arxiv/lean-attention-hardware-aware-scalable-attention-mechanism).
By carefully balancing the softmax and linear attention components, the authors demonstrate that Agent Attention can outperform traditional attention mechanisms on a variety of tasks, making it a promising approach for advancing the state of the art in transformer models.
## Technical Explanation
The paper introduces a novel attention module called Agent Attention, which combines softmax and linear attention in a principled way. Softmax attention assigns importance to each input element based on its similarity to the current output, while linear attention assigns importance based on a linear transformation of the input.
The key innovation of Agent Attention is the way it integrates these two attention mechanisms. Instead of using them in isolation, the model learns a set of "agents" that can dynamically switch between softmax and linear attention, depending on the input and the task at hand. This allows the model to capture both local and global dependencies in the data, leading to improved performance and efficiency.
The authors evaluate Agent Attention on a range of tasks, including image recognition, object detection, and language modeling. They show that Agent Attention outperforms traditional attention mechanisms on these tasks, demonstrating its versatility and effectiveness.
One of the strengths of Agent Attention is its ability to adapt to different hardware constraints, as shown in the [Mansformer](https://aimodels.fyi/papers/arxiv/mansformer-efficient-transformer-mixed-attention-image-deblurring) and [Lean Attention](https://aimodels.fyi/papers/arxiv/lean-attention-hardware-aware-scalable-attention-mechanism) papers. By balancing the softmax and linear attention components, the authors are able to create a more [hardware-aware attention mechanism](https://aimodels.fyi/papers/arxiv/lean-attention-hardware-aware-scalable-attention-mechanism) that can be efficiently deployed on a variety of devices.
## Critical Analysis
The paper presents a compelling approach to attention mechanisms, but it's important to consider some potential limitations and areas for further research.
One potential concern is the complexity of the Agent Attention module, which may make it more challenging to optimize and deploy at scale. The authors address this to some extent by showing the module's efficiency on various hardware platforms, but further research may be needed to fully understand its scalability and practical implications.
Additionally, the paper focuses on a relatively narrow set of tasks, and it would be interesting to see how Agent Attention performs on a broader range of applications, such as more complex language understanding or multi-modal tasks. Exploring the generalizability of the approach could help demonstrate its true potential.
Finally, the paper does not delve deeply into the interpretability and explainability of the Agent Attention module. Understanding the inner workings of the attention mechanism and how it makes decisions could be valuable for gaining deeper insights into the model's behavior and for building trust in its use.
Despite these potential areas for further research, the paper makes a significant contribution to the field of attention mechanisms, and the Agent Attention module represents an exciting step forward in the quest to create more powerful and efficient transformer models.
## Conclusion
The paper introduces a novel attention mechanism called Agent Attention, which integrates softmax and linear attention in a principled way. By dynamically balancing these two attention approaches, Agent Attention is able to capture both local and global dependencies in the data, leading to improved performance and efficiency on a variety of tasks.
The authors' evaluation of Agent Attention on image recognition, object detection, and language modeling tasks demonstrates its versatility and potential to advance the state of the art in transformer models. The module's hardware-aware design, as shown in the [Mansformer](https://aimodels.fyi/papers/arxiv/mansformer-efficient-transformer-mixed-attention-image-deblurring) and [Lean Attention](https://aimodels.fyi/papers/arxiv/lean-attention-hardware-aware-scalable-attention-mechanism) papers, also suggests that it could be effectively deployed on a wide range of devices.
While the paper raises some questions about the complexity and interpretability of the Agent Attention module, its core contribution of integrating softmax and linear attention in a novel way is a significant step forward in the ongoing quest to create more powerful and efficient transformer models.

## Overview
- The researchers explore how continued pre-training on domain-specific corpora affects large language models.
- They find that while pre-training on raw domain-specific data provides the model with relevant knowledge, it can significantly hurt its ability to answer questions based on that knowledge.
- Inspired by how humans learn through reading comprehension, the researchers propose a method to transform raw corpora into reading comprehension texts, which enhances model performance across various tasks in different domains.
- Their approach is highly scalable and applicable to any pre-training corpora.
- The researchers demonstrate that their domain-specific reading comprehension texts can also improve a model's performance on general benchmarks, suggesting the potential to develop a general model across multiple domains.
## Plain English Explanation
The researchers wanted to understand how training large language models on domain-specific data, such as texts about medicine or finance, would affect the models' performance. They found that while this pre-training gave the models a lot of knowledge about the specific domain, it actually made it harder for them to answer questions based on that knowledge.
To address this, the researchers took inspiration from how humans learn. When people read something, they often improve their ability to answer questions about it if they also practice comprehension activities related to the content. So the researchers developed a way to transform raw domain-specific texts into reading comprehension exercises, with questions and other tasks to help the language model better learn and apply the information.
This approach consistently improved the model's performance on various tasks in different domains, like medicine, finance, and law. Interestingly, the researchers also found that using these domain-specific reading comprehension texts could boost the model's performance on general benchmarks, suggesting the potential to develop a single language model that works well across many different areas.
The researchers have made their model, code, and data available online for others to use and build upon.
## Technical Explanation
The researchers explored the impact of continued pre-training on domain-specific corpora for large language models. They found that while pre-training on raw domain-specific data [link to "using-pretrained-large-language-model-prompt-engineering"] endows the model with relevant knowledge, it can drastically hurt its ability to answer questions based on that knowledge.
To address this, they were inspired by how humans learn through reading comprehension - practicing questions and activities after reading improves one's ability to apply the learned knowledge. The researchers proposed a method to transform raw corpora into reading comprehension texts, where each text is enriched with a series of tasks related to its content. This approach is highly scalable and applicable to any pre-training corpora.
The researchers' method consistently enhanced performance across various tasks in three different domains: biomedicine, finance, and law. Notably, their 7B language model achieved competitive performance with domain-specific models of much larger scales, such as BloombergGPT-50B [link to "comprehensive-study-german-language-models-clinical-biomedical"].
Furthermore, the researchers demonstrated that domain-specific reading comprehension texts can improve the model's performance even on general benchmarks, suggesting the potential to develop a general model across even more domains [link to "can-llms-augment-low-resource-reading-comprehension"].
## Critical Analysis
The researchers' approach of transforming raw corpora into reading comprehension texts is a promising solution to the challenge of endowing language models with domain-specific knowledge while maintaining their ability to apply that knowledge effectively. However, the paper does not provide a detailed analysis of the limitations of this method.
One potential concern is the scalability of generating high-quality reading comprehension tasks for large-scale corpora. The researchers mention that their approach is highly scalable, but the process of creating appropriate questions and activities for each text may become increasingly challenging as the corpus size grows.
Additionally, the paper does not explore the potential biases or representational issues that may arise from the specific reading comprehension tasks used. The choice of tasks and the way they are designed could inadvertently introduce biases or skew the model's understanding of the domain.
Further research could investigate the robustness of this approach across a wider range of domains, as well as the long-term impacts on the model's generalization abilities. Exploring the trade-offs between domain-specific and general performance would also be an important area for future work.
## Conclusion
The researchers have proposed a novel approach to address the challenge of endowing large language models with domain-specific knowledge while maintaining their ability to apply that knowledge effectively. By transforming raw corpora into reading comprehension texts, their method consistently enhances performance across various tasks in different domains, including biomedicine, finance, and law.
Notably, the researchers have demonstrated that their approach can enable a smaller language model to achieve competitive performance with much larger, domain-specific models. This suggests the potential to develop a general language model that performs well across a wide range of domains, which could have significant implications for the field of natural language processing and its applications in various industries.
The researchers have made their model, code, and data publicly available, allowing others to build upon their work and explore the further potential of this approach. As the field of large language models continues to evolve, this research represents an important step towards developing more versatile and effective models that can be applied to a diverse range of real-world problems.

- Conclusion
Word search puzzles have long been a favorite pastime, combining cognitive challenge with visual engagement. In this article, we'll explore how to create an interactive word search puzzle using HTML, CSS, and dynamic animations, as demonstrated in my recent project.
Project Overview
The Word Search Puzzle project aims to provide users with an enjoyable experience while finding specific words within a grid of letters. This project was inspired by the challenge presented in "THIS WEEK'S CHALLENGE: Word Puzzles" on CodePen, where interactive elements and design aesthetics play a crucial role in user interaction and satisfaction.
Designing the Puzzle Interface
The puzzle interface consists of a grid of letters where users can visually locate words from a provided list. Each letter is encapsulated within a <span> element, allowing for precise styling and interaction through CSS. The layout is responsive, ensuring compatibility across various devices.
Animated Background for Visual Appeal
One of the key design decisions was the implementation of a dynamic, animated background. This background transitions between different colors using CSS animations (@keyframes), creating an engaging visual effect that complements the puzzle-solving experience. The use of CSS variables (--color-1 to --color-5) facilitates seamless transitions, enhancing the overall aesthetic appeal of the puzzle. `:root {
--color-1: #ff0000;
--color-2: #00ff00;
--color-3: #0000ff;
--color-4: #ffff00;
--color-5: #ff00ff;
}
@keyframes color-flash {
0%, 20% { background-color: var(--color-1); }
21%, 40% { background-color: var(--color-2); }
41%, 60% { background-color: var(--color-3); }
61%, 80% { background-color: var(--color-4); }
81%, 100% { background-color: var(--color-5); }
}`
Enhancing User Experience
The animated background serves not only as a visual delight but also as a subtle cue to users, marking progress or simply providing a dynamic backdrop that prevents visual monotony. This enhances user engagement throughout the puzzle-solving session, making it more enjoyable and immersive.
Further Learning and Resources
If you're interested in exploring more about CSS animations and creating interactive web elements, the MDN Web Docs on CSS Animations provide comprehensive guidance and examples. They cover everything from basic animations to advanced techniques, enabling you to create visually appealing projects like this word search puzzle.
Conclusion
Creating interactive puzzles with dynamic animations can significantly elevate the user experience and engagement. By leveraging CSS animations effectively, you can add visual interest and enhance the usability of your projects. Experimenting with different animation techniques allows for creativity and customization, ensuring your puzzles not only challenge but also delight your audience. in my case, these are sections https://developer.mozilla.org/en-US/docs/Web/CSS/animation https://developer.mozilla.org/en-US/docs/Web/CSS/Using_CSS_custom_properties https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_animations

Maybe you've heard whispers of its power and flexibility but are intimidated by its reputation for complexity. Fear not! This beginner's guide will demystify Linux, explain its key differences from Windows, and show you why it's worth exploring.
## What Makes Linux Special?
Linux isn't just another operating system; it's a philosophy. Here's what sets it apart:
**Open Source Freedom:** Linux is free to use, modify, and distribute. Its source code is open for anyone to inspect and improve, fostering a vibrant community of developers and users.
**Customization Galore:** Want to change your desktop environment, tweak system settings, or even build your own custom kernel? Linux gives you the power to tailor your experience to your exact preferences.
**Security & Stability:** Thanks to its open-source nature and faster patch cycles, Linux is often considered more secure and stable than Windows.
**The Command Line:** Linux embraces the command line, a powerful text-based interface that unlocks a world of possibilities. Don't worry, it's not as scary as it sounds!
## Linux vs. Windows: A Head-to-Head
## Choosing Your Path
So, which operating system is right for you? Here's a quick guide:
Linux: If you're a developer, system administrator, tinkerer, or privacy advocate who values control and flexibility, Linux might be your perfect match.
Windows: If you prefer a user-friendly graphical interface, use commercial software, and primarily want your computer for everyday tasks and gaming, Windows might be a better fit.
## Taking the Plunge into Linux
Ready to give Linux a try? Here's how to get started:
Choose a Distro: Ubuntu, Fedora, Linux Mint – there's a Linux distribution for everyone. Do some research and find one that suits your needs.
Install: Dual-boot alongside Windows or try it out in a virtual machine.
Learn the Ropes: Explore the command line, package managers, and the unique structure of Linux systems. There are countless tutorials and resources available online.
## Linux File System Hierarchy and File Creation
In the Linux operating system, everything is organized within a hierarchical file system structure. This structure starts with the root directory, denoted by a forward slash (/), and branches out into various subdirectories, each serving a specific purpose.
**/home:** This directory is where regular users store their personal files and data. Each user typically has their own subdirectory within /home.
**/root:** This is the home directory for the root user, who has administrative privileges over the system.
**/boot:** This directory contains essential files required for booting the Linux system, such as the kernel and initial RAM disk (initrd).
**/etc:** This directory stores system-wide configuration files that control the behavior of various software and services.
**/usr:** This directory contains user-related programs and data that are not essential for system operation. It often includes subdirectories for shared libraries, documentation, and applications.
**/bin:** This directory contains essential command-line utilities (binaries) that are available to all users.
**/sbin:** Similar to /bin, this directory contains essential system binaries, but these are typically used by the root user for administrative tasks.
**/opt:** This directory is intended for optional or add-on software packages that are not part of the standard Linux distribution.
**/dev:** This directory contains special files that represent devices connected to the system, such as hard drives, USB devices, and terminals.
## Creating Files in Linux
Linux offers several ways to create files, each with its own advantages:
**cat:** The cat command is primarily used to concatenate (combine) files, but it can also be used to create new files. To create a file using cat, you would use the following syntax:
cat > filename
This will open a text editor where you can enter the content of the file. Press Ctrl+D to save and exit.
**touch:** The touch command is used to create empty files or update the timestamps (access, modify, change) of existing files. To create a new empty file, you would use:
touch filename
## Vi/Vim Editor
Vi (or its enhanced version, Vim) is a versatile and powerful text editor widely used by programmers and system administrators in Linux environments. It operates in different modes, each with its own set of commands:
**Command Mode (default)**: In this mode, you can navigate the text, delete characters or lines, copy and paste text, and perform other editing actions using specific key combinations.
**Navigation:**
h (left), j (down), k (up), l (right): Move the cursor.
w (next word), b (previous word): Move by words.
0 (start of line), $ (end of line): Move to the beginning or end of a line.
G (end of file): Move to the end of the file.
Editing:
x: Delete the character under the cursor.
dd: Delete the current line.
yy: Copy the current line.
p: Paste the copied text after the cursor.
Insert Mode: This mode allows you to insert text into the file. You can enter insert mode using various commands:
i: Insert before the cursor.
a: Insert after the cursor.
o: Open a new line below the cursor and insert.
O: Open a new line above the cursor and insert.
To exit insert mode and return to command mode, press Esc.
**Visual Mode:** This mode lets you select blocks of text for operations like copying, deleting, or formatting. You can enter visual mode using:
v: Character-wise visual mode.
V: Line-wise visual mode.
Once in visual mode, you can use navigation commands to extend the selection and then perform actions on the selected text.
Saving and Exiting Vi/Vim
:w: Save the file.
:q: Quit Vi/Vim (if no changes were made).
:wq or :x: Save and quit.
:q!: Quit without saving (discard changes).
## Nano Editor
Nano is a more user-friendly text editor compared to Vi/Vim. It displays a menu at the bottom of the screen with common commands and their corresponding shortcuts.
Navigation: Use the arrow keys to move the cursor.
**Editing:**
Ctrl+K: Cut the current line.
Ctrl+U: Paste the cut line.
Ctrl+O: Save the file.
Ctrl+X: Exit Nano.
**Additional Notes**
Both Vi/Vim and Nano are available in most Linux distributions.
Vi/Vim offers more advanced features and customization options, making it a preferred choice for experienced users.
Nano is easier to learn and use, making it a good option for beginners or those who prefer a simpler interface.
## Creating and Managing Files and Directories in Linux
In the Linux operating system, everything is treated as a file, including directories. Let's explore how to create and manage these files and directories using the command line.
### Creating Directories:
To create a single directory: mkdir directory_name
To create multiple directories: mkdir dir1 dir2 dir3
To create nested directories: mkdir -p dir1/dir2/dir3
### Navigating Directories:
**To move into a directory:** cd directory_name
**To move up one level:** cd ..
**To go to the home directory:** cd or cd ~
**To see your current location:** pwd
### Listing Files and Directories:
**To list files and directories:** ls
**To list all files, including hidden ones:** ls -a
**To list files with details (permissions, size, etc.):** ls -l
### Creating Files:
**To create an empty file:** touch file_name
**To create or edit a file with the vi editor:** vi file_name
**To create or edit a file with the nano editor:** nano file_name
### Copying, Moving, and Renaming:
**To copy a file:** cp source_file destination_file
**To move a file (or rename):** mv source_file destination_file
### Removing Files and Directories:
**To remove an empty directory:** rmdir directory_name
**To remove a file:** rm file_name
**To remove a directory and its contents:** rm -r directory_name (use with caution!)
**Important Note:** Be extremely careful when using the rm -r command, as it can permanently delete files and directories.
### Viewing File Contents:
**To view the first few lines of a file:** head file_name
**To view the last few lines of a file:** tail file_name
**To view the entire file:** cat file_name
**To view the file with pagination:** less file_name or more file_name
### Networking Commands:
**ifconfig (interface configuration):** This command displays information about your network interfaces, including IP addresses, MAC addresses, and network status. It's essential for troubleshooting network issues.
**hostname:** This command simply shows the hostname of your Linux machine. The hostname is a label that identifies your computer on a network.
### System Information:
**cat /etc/os-release:** This command reveals details about your Linux distribution, such as its name, version, and ID. It's helpful for knowing exactly what flavor of Linux you're running.
Package Management (YUM):
**yum (Yellowdog Updater, Modified):** This is a powerful package manager used in Red Hat-based Linux distributions (like CentOS and Fedora). It simplifies the process of installing, updating, and removing software packages.
**yum install package_name:** Installs a package.
**yum remove package_name:** Removes a package.
**yum update package_name:** Updates a package.
**yum list installed:** Lists installed packages.
**yum search keyword:** Searches for packages matching a keyword.
### Text Processing:
**grep (global regular expression print):** This command is a text-searching powerhouse. It allows you to search for specific patterns (text strings) within files.
**grep pattern file_name:** Searches for the pattern in the file.
**grep -r pattern directory:** Recursively searches for the pattern in a directory and its subdirectories.
**sort:** This command sorts the lines of text files in alphabetical or numerical order.
**sort file_name:** Sorts the file.
**sort -r file_name:** Sorts in reverse order.
**sort -n file_name:** Sorts numerically.
### User Management:
**useradd:** This command is used to create new user accounts on your Linux system.
**useradd username:** Creates a user with the specified username.
**useradd -m username:** Creates a user with a home directory.
**useradd -g groupname username:** Creates a user and assigns them to a specific group.
## Understanding Linux Access Modes/Permissions
In the Linux operating system, access modes, also known as permissions, are a fundamental concept for managing file and directory security. They determine who can read, write, and execute files or traverse directories. Let's break down the components of Linux permissions:
### File Types and Permissions:
**Regular Files (-):** These are standard files containing data, text, or code. Permissions for regular files control reading, writing, and executing.
**Directories (d):** Directories organize files and other directories. Permissions for directories control reading (listing contents), writing (creating or deleting files within), and executing (entering the directory).
**Permission Representation:**
Permissions are represented using a combination of letters and
### Symbols:
**r:** Read permission (allows viewing file contents or listing directory contents)
**w:** Write permission (allows modifying file contents or creating/deleting files within a directory)
**x:** Execute permission (allows running a file as a program or entering a directory)
**-:** Absence of a permission
### User Classes:
Permissions are applied to three user classes:
**Owner (u):** The user who owns the file or directory.
**Group (g):** Users belonging to the group associated with the file or directory.
**Others (o):** All other users who are not the owner or in the group.
### Symbolic Notation:
Permissions can be represented using symbolic notation:
**chmod u+x file1:** Adds execute permission for the owner of 'file1'
**chmod g-w file1:** Removes write permission for the group associated with 'file1'
**chmod o=rwx file1:** Sets read, write, and execute permissions for others for 'file1'
### Numeric Notation:
Permissions can also be represented using numeric notation (octal values):
**chmod 777 file1:** Grants read, write, and execute permissions to all user classes for 'file1'
**chmod 644 file1:** Grants read and write permissions to the owner, and read-only permission to group and others for 'file1'
### Example:
Let's say we have a file named "document.txt" with the following permissions:
-rw-r--r-- 1 user group 1024 Jul 15 10:30 document.txt
This means:
File Type: Regular file (-)
Owner (user): Has read (r) and write (w) permissions.
Group (group): Has read (r) permission.
Others: Have read (r) permission.
Changing Permissions:
You can modify permissions using the chmod command. For instance, to give execute permission to the owner and group, you would use:
chmod ug+x document.txt
### Key Considerations:
Understanding and managing permissions is crucial for maintaining the security and integrity of your Linux system.
Be cautious when assigning permissions, especially write and execute permissions, to prevent unauthorized access or modifications.

1,925,486 | Location Services- the Android 14 (maybe 15 too) way | Introduction Location awareness is becoming an essential part of many successful mobile... | 0 | 2024-07-16T13:01:38 | https://dev.to/olubunmialegbeleye/location-services-the-android-14-maybe-15-too-way-4171 | ## Introduction
Location awareness is becoming an essential part of many successful mobile applications. Whether you're building a fitness tracker, a navigation app, a ride-sharing app, a weather app, an augmented reality experience or a service that connects users based on proximity, incorporating location functionality can significantly enhance your app's value and user experience.
This article helps you leverage the Location API in Android, providing a step-by-step approach to accessing the user's location, handling permissions, and setting up real-time location updates. By the end of this tutorial, you'll be well-equipped to integrate location-based features seamlessly into your Android projects.
## Setting up your project to use the Location API
If you don't already have a project set up, follow the following steps:
Open Android Studio.
Go to **File** > **New** > **New Project**.
Select **Basic Views Activity**
Enter a name for your app
Click **Finish**
Open your `app/build.gradle` file and add the following dependency
```
dependencies {
//Location
implementation 'com.google.android.gms:play-services-location:20.0.0'
}
```
If you use the Gradle Kotlin DSL, add the following to the `libs.versions.toml` file
```
[versions]
...
playlocation = "21.3.0"
[libraries]
...
play-location = { group = "com.google.android.gms", name = "play-services-location", version.ref = "playlocation"}
[plugins]
...
```
And in the `app/build.gradle.kts` file, add this
```
dependencies {
...
implementation(libs.play.location)
}
```
Click on **Sync Project with Gradle Files** so that the just added dependency is available for use in your code.
Add the following permissions to your AndroidManifest file
```
<manifest ...>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
...
</manifest>
```
- **ACCESS_FINE_LOCATION**: Grants access to the device's most precise location data (GPS, Wi-Fi, cell tower triangulation).
- **ACCESS_COARSE_LOCATION**: Provides a less accurate estimate using cell tower and Wi-Fi data (suitable for scenarios where exact coordinates aren't crucial).
## Checking If your App has permission
`Activity.checkSelfPermission()` checks if you have been granted a particular permission. To check if you have the `Manifest.permission.ACCESS_FINE_LOCATION` permission, you would do:
`ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)`
Let's use that to build a function that checks for the two permissions we need.
Add the following to the activity.
> _(Code snippets are presented first in Kotlin and then in Java)_
```
private fun isLocationPermissionGranted(activity: Activity): Boolean {
return ActivityCompat.checkSelfPermission(
activity,
Manifest.permission.ACCESS_FINE_LOCATION
) == PackageManager.PERMISSION_GRANTED ||
ActivityCompat.checkSelfPermission(
activity,
Manifest.permission.ACCESS_COARSE_LOCATION
) == PackageManager.PERMISSION_GRANTED
}
```
```
private boolean isLocationPermissionGranted(Activity activity) {
return ActivityCompat.checkSelfPermission(activity, android.Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED ||
ActivityCompat.checkSelfPermission(activity, android.Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED;
}
```
This function checks if your app has the permission to access the device's coarse or fine location.
## Requesting Permission at runtime
In the activity where location is needed, you must request permission at runtime. We will use an `ActivityResultLauncher` to request permission and listen for the response to our request. To indicate the kind of request, we have two options. `ActivityResultContracts.RequestMultiplePermissions()` or `ActivityResultContracts.RequestPermission()`. We will use the former because we have two permissions to request.
The next function requests for the needed permissions.
```
private fun requestLocationPermission(callback: (Boolean) -> Unit) {
val locationPermissionRequest = registerForActivityResult(
ActivityResultContracts.RequestMultiplePermissions()
) { permissions ->
val fineLocationGranted: Boolean =
permissions.getOrDefault(Manifest.permission.ACCESS_FINE_LOCATION, false)
val coarseLocationGranted: Boolean =
permissions.getOrDefault(Manifest.permission.ACCESS_COARSE_LOCATION, false)
if (fineLocationGranted || coarseLocationGranted) {
callback(true) //permission granted
} else {
callback(false) //permission denied
}
}
locationPermissionRequest.launch(
arrayOf(
Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.ACCESS_COARSE_LOCATION
)
)
}
```
```
private void requestLocationPermission(CallbackListener<Boolean> callbackListener) {
ActivityResultLauncher<String[]> locationPermissionRequest = registerForActivityResult(
new ActivityResultContracts.RequestMultiplePermissions(),
permissions -> {
Boolean fineLocationGranted = permissions.getOrDefault(android.Manifest.permission.ACCESS_FINE_LOCATION, false);
Boolean coarseLocationGranted = permissions.getOrDefault(android.Manifest.permission.ACCESS_COARSE_LOCATION, false);
if (
fineLocationGranted != null && fineLocationGranted ||
coarseLocationGranted != null && coarseLocationGranted
) {
// Permission granted
callbackListener.onCallback(true);
} else {
// No location access granted.
callbackListener.onCallback(false);
}
});
locationPermissionRequest.launch(new String[]{
android.Manifest.permission.ACCESS_FINE_LOCATION,
android.Manifest.permission.ACCESS_COARSE_LOCATION
});
}
```
The result, `permissions`, is a `Map` containing the permissions requested and whether they were granted. We look at the map for the two permissions requested. If either of them were granted, we're good. Else, we cannot use the Location API. You may present the user with a warning to let them know that some features may be unavailable or may not function properly since they have not granted the app the permission to access their device location.
## Check Phone's Location Settings
Let's say the user granted the permission to access the device's location, we also need to check if the device's settings satisfy our requirements. For example, the device's location may be off. In this case, we cannot access the location.
First, we build a location request. This is our way of specifying our requirements.
Add the following field to your Activity
```
private val locationRequest = LocationRequest.Builder(Priority.PRIORITY_HIGH_ACCURACY, 5000)
.build()
```
```
private final LocationRequest locationRequest = new LocationRequest.Builder(Priority.PRIORITY_HIGH_ACCURACY, 5000)
.build();
```
We use `SettingsClient.checkLocationSettings()` to check if our requirement is met. If the requirement is met, we can proceed to the next step. If it isn't met, we need to ask the user to update their setting.
For that, we need an `ActivityResultLauncher` to launch the request and listen for the user's action.
Add this field to your Activity.
```
private val locationSettingsResult =
registerForActivityResult(ActivityResultContracts.StartIntentSenderForResult()) { result ->
when (result.resultCode) {
Activity.RESULT_OK -> {
//User has updated the device's setting
}
Activity.RESULT_CANCELED -> {
//Warn user that location is required for some features
}
}
}
```
```
private ActivityResultLauncher<IntentSenderRequest> locationSettingsResult;
public void onCreate(@Nullable Bundle savedInstanceState) {
locationSettingsResult = registerForActivityResult(new ActivityResultContracts.StartIntentSenderForResult(), result -> {
if (result.getResultCode() == Activity.RESULT_OK) {
//User has updated the device's setting
} else {
//Warn user that location is required for some features
}
});
}
```
This `ActivityResultContracts` must be registered before the Activity starts, or the app will crash.
Putting it all together we have this function to check the device's location setting and ask the user to update their location settings if there is a need:
```
private fun checkPhoneLocationSettings(
activity: Activity,
locationSettingsResult: ActivityResultLauncher<IntentSenderRequest>,
callback: (Boolean) -> Unit
) {
val builder = LocationSettingsRequest.Builder().addLocationRequest(locationRequest)
val client = LocationServices.getSettingsClient(activity)
val task = client.checkLocationSettings(builder.build())
task.addOnSuccessListener { callback(true) }
task.addOnFailureListener { exception ->
if (exception is ResolvableApiException) {
try {
locationSettingsResult.launch(
IntentSenderRequest.Builder(exception.resolution).build()
)
} catch (sendEx: IntentSender.SendIntentException) {
// Ignore the error.
}
}
}
}
```
```
private void checkPhoneLocationSettings(
Activity activity,
ActivityResultLauncher<IntentSenderRequest> locationSettingsResult,
CallbackListener<Boolean> callbackListener) {
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest);
SettingsClient client = LocationServices.getSettingsClient(activity);
Task<LocationSettingsResponse> task = client.checkLocationSettings(builder.build());
task.addOnSuccessListener(activity, locationSettingsResponse -> {
//Location settings are fine. You can start listening for location
callbackListener.onCallback(true);
});
task.addOnFailureListener(activity, e -> {
if (e instanceof ResolvableApiException) {
locationSettingsResult.launch(new IntentSenderRequest.Builder(((ResolvableApiException) e).getResolution()).build());
}
});
}
```
At this point, we have what we need to check if we have location permission. If we don't we can request the permissions. After which we can check if the settings meet our location requirements. Let's package all of that into a function.
```
private fun setUpLocationComponentsAndGetLocation(activity: Activity) {
if (isLocationPermissionGranted(activity)) {
checkPhoneLocationSettings(activity) { isLocationSettingsOk ->
if (isLocationSettingsOk) {
//You can get last known location or request location update here because you have permission
//and the device settings meet your requirement.
} else {
//warn user
}
}
} else {
requestLocationPermission { permissionGranted ->
if (permissionGranted) {
//simply a recursive call
setUpLocationComponentsAndGetLocation(activity)
} else {
//warn user
}
}
}
}
```
```
private void setUpLocationComponentsAndGetLocation(Activity activity) {
if (isLocationPermissionGranted(activity)) {
checkPhoneLocationSettings(activity, locationSettingsResult, isLocationSettingsOk -> {
if (isLocationSettingsOk) {
//You can get last known location or request location update here because you have permission
//and the device settings meet your requirement.
} else {
//You may decide to warn users that some functions may not be available without permission
}
});
} else {
requestLocationPermission(permissionGranted -> {
if (permissionGranted) {
//simply a recursive call
setUpLocationComponentsAndGetLocation(activity);
} else {
//Warn user
}
});
}
}
```
## Accessing Location
At this point, we can now access the device's location. `FusedLocationProviderClient` is the main entry point for interacting with the Fused Location Provider - the Location API by Google for accessing user location. To begin, add this field to your Activity:
```
private val mFusedLocationProviderClient: FusedLocationProviderClient by lazy {
LocationServices.getFusedLocationProviderClient(this)
}
```
```
private FusedLocationProviderClient fusedLocationProviderClient;
@Override
protected void onStart() {
super.onStart();
fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(this);
}
```
There are two methods of concern to us in the FusedLocationProviderClient class:
`FusedLocationProviderClient.getLastLocation()` retrieves the last known location while `FusedLocationProviderClient.requestLocationUpdates()` listens for Location updates.
For the former, think of Weather apps that get your current city and display the weather in that area. For the latter, think of Bolt or Uber which needs to get updates on the driver and rider's location.
## Retrieving the last known location
To retrieve the last known location of the device,
```
@SuppressLint("MissingPermission")
private fun getLastLocation() {
mFusedLocationProviderClient.lastLocation.addOnSuccessListener { location ->
if (location != null) {
// Logic to handle location object
Log.d("Location", "Long" + location.longitude)
Log.d("Location", "Lat" + location.latitude)
}
}
}
```
```
@SuppressLint("MissingPermission")
private void getLastLocation() {
fusedLocationProviderClient.getLastLocation().addOnSuccessListener(location -> {
// Got last known location. In some rare situations this can be null.
if (location != null) {
// Logic to handle location object
Log.d("Location", "Long" + location.getLongitude());
Log.d("Location", "Lat" + location.getLatitude());
}
});
}
```
Notice that you need to check for null because the last location may be null at some point.
## Setting up Location Updates for Real-time tracking
This requires some more work compared to retrieving the last known location because we need to set up a callback and manage lifecycle.
For the callback, add this field to your Activity:
```
private val locationCallBack = object : LocationCallback() {
override fun onLocationResult(locationResult: LocationResult) {
super.onLocationResult(locationResult)
Log.d("Location", "Long" + locationResult.lastLocation?.longitude)
Log.d("Location", "Lat" + locationResult.lastLocation?.latitude)
}
}
```
```
private final LocationCallback locationCallback = new LocationCallback() {
@Override
public void onLocationResult(@NonNull LocationResult locationResult) {
super.onLocationResult(locationResult);
if (locationResult.getLastLocation() != null) {
Log.d("Location", "Long: " + locationResult.getLastLocation().getLongitude());
Log.d("Location", "Lat: " + locationResult.getLastLocation().getLatitude());
}
}
};
```
Remember we created a `LocationRequest` object when checking if the device setting meets our requirement. Well, we need the same object now.
Create this function in your Activity
```
@SuppressLint("MissingPermission")
private fun requestLocationUpdate(activity: Activity) {
if (isLocationPermissionGranted(activity)) {
mFusedLocationProviderClient.requestLocationUpdates(
locationRequest,
locationCallBack,
Looper.getMainLooper()
)
}
}
```
```
@SuppressLint("MissingPermission")
private void requestLocationUpdate(Activity activity) {
if (isLocationPermissionGranted(activity)) {
fusedLocationProviderClient.requestLocationUpdates(
locationRequest,
locationCallback,
Looper.getMainLooper()
);
}
}
```
## Connecting it all up
Now that we have the function to Get the last known location and request location updates, it is time to update our `setUpLocationComponentsAndGetLocation()`
from before. Add the new lines to the `setUpLocationComponentsAndGetLocation()` function.
```
private fun setUpLocationComponentsAndGetLocation(activity: Activity) {
if (isLocationPermissionGranted(activity)) {
checkPhoneLocationSettings(activity) { isLocationSettingsOk ->
if (isLocationSettingsOk) {
getLastLocation() //Add only this line to get the last location
requestLocationUpdate(activity) //Add only this line, to request location updates
} else {
//warn user
}
}
} else {
requestLocationPermission { permissionGranted ->
if (permissionGranted) {
//simply a recursive call
setUpLocationComponentsAndGetLocation(activity)
} else {
//warn user
}
}
}
}
```
```
private void setUpLocationComponentsAndGetLocation(Activity activity) {
if (isLocationPermissionGranted(activity)) {
checkPhoneLocationSettings(activity, locationSettingsResult, isLocationSettingsOk -> {
if (isLocationSettingsOk) {
getLastLocation(); //Add only this line to get the last location
requestLocationUpdate(activity); //Add only this line, to request location updates
} else {
//You may decide to warn users that some functions may not be available without permission
}
});
} else {
requestLocationPermission(permissionGranted -> {
if (permissionGranted) {
//simply a recursive call
setUpLocationComponentsAndGetLocation(activity);
} else {
//Warn user
}
});
}
}
```
To get location or request location update, all you need do at this point is to call the `setUpLocationComponentsAndGetLocation()` from the entry point of the Activity that needs location data. Usually, this is the `onStart()` method.
```
override fun onStart() {
super.onStart()
setUpLocationComponentsAndGetLocation(this)
}
```
```
@Override
protected void onStart() {
super.onStart();
setUpLocationComponentsAndGetLocation(this);
}
```
## Cleaning up after yourself
One final and important thing. When you no longer require the location updates, you need to unsubscribe. This most likely happens when the user navigates away from the Activity that requires the location update. It is a best practice to stop location updates by removing the location callback. This way, you can avoid unnecessarily draining the device battery.
```
override fun onStop() {
mFusedLocationProviderClient.removeLocationUpdates(locationCallBack)
super.onStop()
}
```
```
@Override
protected void onStop() {
fusedLocationProviderClient.removeLocationUpdates(locationCallback);
super.onStop();
}
```

1,925,488 | Cloud Computing 101: An Introduction to Cloud Solutions | Explore the fundamentals of cloud computing, its benefits for businesses, and the various types of cloud services available. Learn how cloud computing revolutionizes IT management by offering scalable, cost-effective solutions for modern enterprises. | 0 | 2024-07-16T13:05:21 | https://www.citruxdigital.com/blog/cloud-computing-101-an-introduction-to-cloud-solutions | In today’s fast-paced world, cloud computing has become a cornerstone of modern technology. But what exactly is cloud computing, and why has it become so essential? Let’s break it down in simple terms and see why it’s a game-changer for businesses everywhere.
### What is Cloud Computing?
Cloud computing is like renting instead of buying. Instead of investing in expensive servers and storage, businesses can access these resources over the internet. This means you can use powerful tools and store large amounts of data without needing to own the hardware yourself.
### Why Did Cloud Computing Evolve?
The evolution of cloud computing is driven by the need for efficiency, flexibility, and innovation. As businesses grew and technology advanced, the traditional IT model, with its high costs and inflexibility, became a bottleneck. Companies needed a way to scale quickly, innovate faster, and reduce costs – cloud computing was the answer.
### The Big Players
Several major companies have become leaders in cloud computing
1. **Amazon Web Services (AWS)**: The pioneer and largest provider, offering a vast array of services and tools.
2. **Microsoft Azure**: A strong competitor, known for integrating well with Microsoft products.
3. **Google Cloud Platform (GCP)**: Known for its strong data analytics and machine learning capabilities.
### The Story of AWS
Amazon Web Services (AWS) started as an internal solution within Amazon. In the early 2000s, Amazon’s retail business was growing rapidly, and the company faced challenges with scaling its infrastructure. To solve this, Amazon developed a robust and scalable infrastructure that could handle its massive growth. This led to the idea of offering this infrastructure as a service to other businesses.
In 2006, AWS was officially launched, providing services like computing power and storage on a pay-as-you-go basis. This was revolutionary because it allowed businesses of all sizes to access powerful IT resources without significant upfront investment. Over the years, AWS expanded its offerings to include a wide range of services, from databases and machine learning to analytics and Internet of Things (IoT).
Today, AWS is the largest and most comprehensive cloud service provider, continually innovating and adding new services to meet the evolving needs of businesses worldwide .
### Key Benefits of Cloud Computing
1. **Cost Savings:** You only pay for what you use, which eliminates the need for large capital investments in hardware.
2. **Scalability:** Easily scale your resources up or down based on your needs without any delays.
3. **Accessibility:** Access your data and applications from anywhere, at any time, which is perfect for remote work.
4. **Security:** Leading cloud providers offer top-notch security measures, protecting your data from threats.
5. **Innovation:** Cloud platforms offer the tools you need to develop and deploy applications quickly, helping you bring new ideas to life faster.
### Types of Cloud Services
Cloud computing services come in three main types:
1. **Infrastructure as a Service (IaaS)**: Rent IT infrastructure like servers and storage.
2. **Platform as a Service (PaaS)**: Get a platform to develop, test, and deploy applications.
3. **Software as a Service (SaaS)**: Access software applications over the internet, like Google Workspace or Microsoft Office 365.
Cloud computing is transforming the way businesses manage their IT resources, offering numerous benefits such as cost efficiency, scalability, and enhanced security. By understanding the different types of cloud services—Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS)—businesses can make informed decisions about how to leverage the cloud to drive growth and innovation.
### Deployment Models
Cloud services can be deployed in different ways:
* **Public Cloud**: Services are delivered over the internet and shared among multiple organizations.
* **Private Cloud**: Dedicated to a single organization, providing greater control and security.
* **Hybrid Cloud**: Combines public and private clouds, offering flexibility and optimized performance.
### Why Your Business Needs Cloud Computing
Cloud computing isn’t just a tech trend; it’s a vital part of staying competitive. It helps you save money, scale efficiently, improve accessibility, and foster innovation. Whether you’re a small startup or a large enterprise, cloud solutions can help you achieve your goals faster and more effectively.

1,925,489 | Simulate APIs using Postman (Create a mock server) | Simulate APIs using Postman When do we need to Simulate APIs Reproduce... | 0 | 2024-07-16T14:06:01 | https://dev.to/jenchen/simulate-apis-using-postman-create-a-mock-server-3hmg | webdev, postman, api, web | ## Simulate APIs using Postman
### When do we need to Simulate APIs
#### Reproduce Issues in Debugging
Consistent Responses. In production environments, certain API responses are not common. Simulating APIs helps reproduce these responses consistently, aiding in effective debugging and issue resolution.
#### Isolation
Independent Testing. This isolation ensures that frontend development and testing can proceed without waiting for the backend to be fully implemented or available.
#### Documentation and Collaboration
Single Source of Truth. Team members, including product owners, developers, and test engineers, can refer to the same information.
### Setting Up a Mock Server with Custom Responses
Follow this tutorial to set up a mock server using an existing collection: [Mock an API](https://learning.postman.com/docs/designing-and-developing-your-api/mocking-data/mock-an-api/).
If we want always to receive a specific response, such as a `409 Conflict` status, we need to use the `x-mock-response-code` header. According to the [Matching algorithm](https://learning.postman.com/docs/designing-and-developing-your-api/mocking-data/matching-algorithm/), we should add this header to the request. Here is an example of the request and response:

Today's agenda was all about using this nifty tool called Docker Compose. Now, full disclosure, going into this I wasn't entirely sure what I was getting myself into. Docker? Sure, I'd heard the name. But Docker Compose? Was that like a fancy way of writing music for otters?
Thankfully, after some Googling that would make Sherlock Holmes proud (minus the deerstalker, because, well, Kenya is a bit warm for that), I figured it out. Here's the gist: imagine you have two essential parts to your application, like a peanut butter and jelly sandwich. You've got the peanut butter (my awesome API) and the jelly (a database to store all that good data). Docker Compose lets you package these two things up neatly and efficiently, ensuring they always play nicely together.
**The Great Docker Compose Caper**
So, I whipped up a docker-compose.yml file, which is basically a recipe for how to put everything together. Here's what my code looked like:
```yaml
version: '3.1'
services:
verisafe:
image: verisafe:v4
ports:
- "8000:8000"
postgres:
image: postgres:latest
environment:
POSTGRES_USER: verisafe
POSTGRES_PASSWORD: verisafe
POSTGRES_DB: verisafe
ports:
- "5431:5432"
```
It took a bit of work, but hey, nothing worth having comes easy, right? Especially not when you're dealing with lines of code that look like they were written by a particularly enthusiastic alien overlord.
After some tweaking (and maybe a few muttered curses under my breath), I ran the command to get everything up and running. And guess what? It worked! Sort of.
There were some hiccups, let's not sugarcoat it. My fancy API decided it wasn't too keen on talking to the database. Turns out, there was a bit of a communication breakdown. Imagine trying to order a pizza when you and the delivery person speak entirely different languages - that was kind of the vibe.
**AI to the Rescue (Kind Of)**
Here's where things got interesting. I started poking around the internet, trying to decipher the error messages that looked like they were written in binary code. Thankfully, with the help of some friendly online forums (and maybe a little nudge from a large language model that may or may not be me ), I found the culprit: a missing environment variable.
Apparently, my API needed the database's IP address to know where to find it. Oops! ♀️ It was like trying to give directions to your friend's house without knowing the actual address - a recipe for disaster (and a very hangry friend).
**Lessons Learned and What's Next**
So, what did I learn today? Well, a few things:
1. **Docker Compose is pretty darn cool.** It takes the complexity out of managing multiple containers and makes your life a whole lot easier. Just remember to double-check those environment variables - they're kind of like the secret sauce that makes everything work together.
2. **Error messages are not your enemy.** They might be cryptic and confusing, but they're usually there to point you in the right direction. Just be patient and persistent, and eventually you'll crack the code (pun intended).
3. **There's a large language model out there that may or may not be able to help you with your coding woes.** Just sayin'.
Tomorrow's adventure? We're going to explore the wonderful world of CI/CD pipelines. That's a fancy way of saying we're going to automate the process of building and deploying my API. Wish me luck! In the meantime, if you have any Docker Compose tips or tricks, feel free to share them in the comments below. And hey, if you're ever feeling lost in the land of code, don't hesitate to reach out - maybe together we can decipher those alien messages. | tutorialhelldev | |

1,925,493 | How Video Generation Works in the Open Source Project Wunjo CE | Getting to Know the Functionality If you’re interested in exploring the full... | 24,089 | 2024-07-16T13:09:28 | https://dev.to/wladradchenko/how-video-generation-works-in-the-open-source-project-wunjo-ce-1k1 | github, opensource, ai, tutorial | ## Getting to Know the Functionality
If you’re interested in exploring the full functionality, detailed parameter explanations, and usage instructions of Wunjo CE, a comprehensive video will be attached at the end of this article. For those who prefer to skip the technical intricacies, a video demonstrating the video generation process and a comparison with Pika and Gen-2 from Runway will also be provided.
> Anatole France once said, “You can only learn joyfully… To digest knowledge, you must absorb it with appetite.” This sentiment perfectly captures the essence of Wunjo CE: it offers something valuable for everyone, allowing users to engage with the material at their own pace and interest level.
## Specifications for Video Generation
Videos can be created from text and images using Stable Diffusion models. Custom 1.5 models can be added and extended to XL. However, in my opinion, this might not be the best approach since the video generation model doesn’t deliver the quality achievable with Stable Diffusion XL models and requires significantly more power.
## Generation Parameters
- FPS: The maximum is 24 FPS, which allows for up to 4 seconds of video. Lowering the FPS increases the video length.
- VRAM: Video generation is feasible with 8 GB of VRAM.
- Formats: Various aspect ratios are available for text-based generation: 16:9 (YouTube), 9:16 (Shorts), 1:1, 5:2, 4:5, and 4:3. When generating from an image, the original aspect ratio is maintained.
## Generate Video from Text
Initially, an image is generated in your chosen format. You have the option to view the image, regenerate it, or modify details before proceeding to video creation.
## Generate Video from Image
The original aspect ratio of the image is preserved, but you can fine-tune its elements before generating the video.
## Manual setup
If automatic download of the necessary repositories failed, you will need about 85-90 GB of space on your hard drive. You can choose the storage location of the models yourself, more details on this in [GitHub Wiki](https://github.com/wladradchenko/wunjo.wladradchenko.ru/wiki/How-to-change-the-default-directory-for-the-.wunjo-folder).
The program downloads all repositories and models automatically, but there may be problems with downloading from Hugging Face without VPN. In this case, you need to go to the directory `.wunjo/all_models`.
## Download manually
**Runwayml:** This is a repository that includes the necessary models such as vae, safety_checker, text_encoder, unet and others. You need to create a directory [runwayml](https://huggingface.co/runwayml/stable-diffusion-v1-5) and download the models to the appropriate folders.
You can also use a console command to automate this process.
```
git clone https://huggingface.co/runwayml/stable-diffusion-v1-5
```
Before you start downloading, make sure you have the ability to download large files.
```
git lfs install
```
## Downloading Custom Stable Diffusion Models
To the directory `.wunjo/all_models/diffusion` you can download various Stable Diffusion 1.5 models that will be used to generate images. These models can be found in the public domain, for example, at [Hugging Face](https://huggingface.co/models) or [Civitai](https://civitai.com/models).
## Setting up custom_diffusion.json
In file `.wunjo/all_models/custom_diffusion.json` you specify the paths to your models. Example of setup:
```
[
{
"name": "Fantasy World", "model": "fantasyWorld_v10.safetensors", "img": "https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/2e321e71-c144-4ba6-8b55-3f62756fc0a1/width=1024,quality=90/01828-3669354034-giant%20pink%20balloon,cities%20floating%20on%20balloons,magnificent%20clouds,pink%20theme,.jpeg", "url": ""
}
]
```
If you specify the url, then the model is downloaded automatically.
This step can be skipped as two Stable Diffusion 1.5 models are enabled by default, which is sufficient for creating both realistic and hand-drawn content.
## Switching to the diffusers library
Previously, the code worked only with the necessary parts of generative models, which saved time and reduced the amount of unnecessary code. However, to expand the functionality, I decided to switch to the library diffusers. Specifically the repository runwayml used to generate images.
Example code from the project:
```
# Defining the model components runwayml
vae = AutoencoderKL.from_pretrained(sd_path, subfolder="vae", torch_dtype=torch.float16)
text_encoder = CLIPTextModel.from_pretrained(sd_path, subfolder="text_encoder", torch_dtype=torch.float16)
tokenizer = CLIPTokenizer.from_pretrained(sd_path, subfolder="tokenizer")
unet = UNet2DConditionModel.from_pretrained(sd_path, subfolder="unet", torch_dtype=torch.float16)
safety_checker = StableDiffusionSafetyChecker.from_pretrained(sd_path, subfolder="safety_checker", torch_dtype=torch.float16) # to filter naked content
feature_extractor = CLIPImageProcessor.from_pretrained(sd_path, subfolder="feature_extractor")
# If a custom model 1.5 is specified, I load its weights
if weights_path:
weights = load_file(weights_path) # weights_path
unet.load_state_dict(weights, strict=False)
```
You can change Stable Diffusion 1.5 to a more powerful model, since it uses pipelines from the library diffusersTo do this, it is enough to change sd_path And StableDiffusionPipeline.
```
pipe = StableDiffusionPipeline(
vae=vae,
text_encoder=text_encoder,

## ControlNet
ControlNet and the corresponding pipelines are used to change the image elements in the application. Example of the setup:
```
def make_canny_condition(image):
image = np.array(image)
image = cv2.Canny(image, 100, 200)
image = image[:, :, None]
image = np.concatenate([image, image, image], axis=2)
image = Image.fromarray(image)
return image
if controlnet_type == "canny":
control_image = make_canny_condition(init_image)
else:
control_image = init_image
controlnet = ControlNetModel.from_pretrained(controlnet_path, torch_dtype=torch.float16).to(device)
```
By default the canny method is available, but you can extend the application by adding different methods. [ControlNet](https://huggingface.co/docs/diffusers/en/using-diffusers/controlnet). For example, for XL models, you can replace ControlNet with IP-Adapter or [T2I-Adapter](https://huggingface.co/docs/diffusers/en/using-diffusers/t2i_adapter).
## Downloading ControlNet Models
To the directory `.wunjo/all_models` need to create directory controlnet_canny and download models from the repository [sd controlnet canny](https://huggingface.co/lllyasviel/sd-controlnet-canny).
```
git clone https://huggingface.co/lllyasviel/sd-controlnet-canny
```
Also create a directory controlnet_tile and download models from the repository [control_v11f1e_sd15_tile](https://huggingface.co/lllyasviel/control_v11f1e_sd15_tile).
```
git clone https://huggingface.co/lllyasviel/control_v11f1e_sd15_tile
```
_Why ControlNet Tile? More on that later._
## Video generation
To generate videos I use the repository [stabilityai](https://huggingface.co/stabilityai/stable-video-diffusion-img2vid-xt) and the corresponding Pipeline. The question arises: if the model is limited to images of 576×1024 format and generates no more than 25 frames, how can we use any format in the model and get 4 seconds of video at 24 FPS?
```
# Components
vae = AutoencoderKLTemporalDecoder.from_pretrained(sd_path, subfolder="vae", torch_dtype=torch.float16)
image_encoder = CLIPVisionModelWithProjection.from_pretrained(sd_path, subfolder="image_encoder", torch_dtype=torch.float16)
scheduler = EulerDiscreteScheduler.from_pretrained(sd_path, subfolder="scheduler")
unet = UNetSpatioTemporalConditionModel.from_pretrained(sd_path, subfolder="unet", torch_dtype=torch.float16)
feature_extractor = CLIPImageProcessor.from_pretrained(sd_path, subfolder="feature_extractor")
# Init
pipe = StableVideoDiffusionPipeline(
vae=vae,
image_encoder=image_encoder,
scheduler=scheduler,
unet=unet,
feature_extractor=feature_extractor
)
pipe.enable_model_cpu_offload()
pipe.unet.enable_forward_chunking()
pipe.enable_xformers_memory_efficient_attention()
```
## Preparing images
Before feeding the image to the model for video generation, I build it up to 576×1024 format without changing the content of the user frame. After outpaint I use controlnet_tile with the appropriate mask to improve the quality of the added zones. The better the quality of the completed zones, the better the animation. _Generation is better focused on the movement of objects rather than the created zones._
## Generation iterations
The video cannot be generated indefinitely, because the model adds noise to each final frame. After the third iteration, you get a mess of pixels. So I generate the first two iterations, reverse them, generate the iterations again, and combine everything, cropping to the aspect ratio for the user. These tricks expand the possibilities for stabilityai.
## Improving the quality of video generation
You can replace the repository `stable-video-diffusion-img2vid-xt` on `stable-video-diffusion-img2vid-xt-1-1` on Hugging Face to get better video quality than the model I use.
## Comparison
For you, I have collected in one video various examples of generation in comparison with Pika and Gen-2. I have not included Gen-3, Luma, Sora models, since open source models cannot compete with them. From the entire list, I was able to use only Luma for free, and even then with restrictions – for example, no more than 5 generations per day. In this comparison, I focused on approaches that give approximately the same generation time. It is important to understand that Wunjo CE is a completely free and unlimited open source solution.
## Features of the models
By the location of the result on the video.
- Pika: The model does not add much movement, but smooths the result, sometimes even too much. Can add sound to the video.
- Wunjo C.E.: Preserves the original image quality and adds interesting movements to some objects. However, the directions of these movements can randomly change in the frame and generating one video takes 15 minutes on NVIDIA GeForce RTX 3070 8 GB VRAM.
- Gen-2: Adds more realism, but can create distortions for unusual objects. It is possible to increase the duration of the result, but the quality decreases with each iteration,
## Examples of generation
The prompts were simple, like “robotic hand” or “dogs riding in a car”. I used only one video generation for each approach, without specially selecting or improving the results, to demonstrate the real potential of the models.
This particular generation made me laugh: the model created the frames in such a way that it looks like the girl is angrily cursing at life for reasons known only to her.

## Additional Functionality
You can learn about the rest of Wunjo CE's functionality from the video [playlist provided](https://www.youtube.com/playlist?list=PLJG0sD6007zFJyV78mkU-KW2UxbirgTGr). These videos cover the main features, installation instructions (both from the code and installer), and how to use the API for your projects.
## Support the Project
If you'd like to support the project, visit [GitHub](https://github.com/wladradchenko/wunjo.wladradchenko.ru) page and bookmark it to stay updated with the latest developments. Future plans include adding audio generation for videos and creating animations of talking heads from images. You can download installers from the official website [wunjo.online](https://wunjo.online) and [Boosty](https://boosty.to/wunjo). On Boosty, you can vote for which features' code should be open-sourced and made available on GitHub. Your interest drives these decisions.
## Alternatives
No discussion about video generation would be complete without mentioning alternatives. One intriguing open-source project is [ToonCrafter](https://github.com/ToonCrafter/ToonCrafter), which generates hand-drawn animations. It creates motion between the first and last frame, rather than from text or a single image. While the resolution is quite low at 320×512, and I haven't tested its video memory requirements, it's a promising alternative with room for improvement. The ToonCrafter model's ability to add motion to animations is particularly appealing. I collect all interesting solutions for video, voice cloning, and more on [favorite page](https://github.com/wladradchenko?tab=stars).
## Your Suggestions
Please share your open-source video generation alternatives in the comments. Your suggestions will help improve current approaches and contribute to a knowledge base for this exciting new field.
## A Bit of Philosophy
_Generating video from text and images isn't just a technological achievement; it's a new form of creativity and self-expression. Open-source and commercial projects alike are enabling new ways to express ideas, where simple text can produce videos that would otherwise be complex and costly to create._
_Imagine adapting one video for different countries and regions with a single request, altering skin tones, faces, objects, and captions, and adding new elements and videos. The future promises even more realistic and detailed models. Video generation is evolving from a mere tool into a new philosophy in creativity, blending technology, simplicity, and art._
