In this blog post, I demonstrated how to generate replies with multiple Langchain chains. Buyers can provide ratings and comments on sales transactions in auction sites such as eBay. When the feedback is negative, the seller must reply promptly to resolve the dispute. This demo aims to generate responses in the same language of the buyer according to the the tone (positive, neutral or negative) and topics. Previous chains obtain answers from the Gemini model and become the next chain's output. Similarly, the model receives the new prompt to generate the final reply to keep customers happy.
###Generate Gemini API Key
Go to https://aistudio.google.com/app/apikey to generate an API key for a new or an existing Google Cloud project.
###Create a new NestJS Project
```bash
nest new nestjs-langchain-customer-feedback
```
###Install dependencies
```bash
npm i --save-exact @nestjs/swagger @nestjs/throttler dotenv compression helmet @google/generative-ai class-validator class-transformer langchain @langchain/core @langchain/google-genai
```
###Generate a Feedback Module
```bash
nest g mo advisoryFeedback
nest g co advisoryFeedback/presenters/http/advisoryFeedback --flat
nest g s advisoryFeedback/application/advisoryFeedback --flat
nest g s advisoryFeedback/application/advisoryFeedbackPromptChainingService --flat
```
Create an `AdvisoryFeedbackModule` module, a controller, a service for the API, and another service to build chained prompts.
###Define Gemini environment variables
```
// .env.example
PORT=3002
GOOGLE_GEMINI_API_KEY=<google gemini api key>
GOOGLE_GEMINI_MODEL=gemini-1.5-pro-latest
```
Copy `.env.example` to `.env`, and replace `GOOGLE_GEMINI_API_KEY` and `GOOGLE_GEMINI_MODEL` with the actual API Key and the Gemini model, respectively.
- PORT - port number of the NestJS application
- GOOGLE_GEMINI_API_KEY - API Key of Gemini
- GOOGLE_GEMINI_MODEL - Google model and I used Gemini 1.5 Pro in this demo
Add `.env` to the `.gitignore` file to prevent accidentally committing the Gemini API Key to the GitHub repo.
###Add configuration files
The project has 3 configuration files. `validate.config.ts` validates the payload is valid before any request can route to the controller to execute.
```typescript
// validate.config.ts
import { ValidationPipe } from '@nestjs/common';
export const validateConfig = new ValidationPipe({
whitelist: true,
stopAtFirstError: true,
forbidUnknownValues: false,
});
```
`env.config.ts` extracts the environment variables from process.env and stores the values in the env object.
```typescript
// env.config.ts
import dotenv from 'dotenv';
dotenv.config();
export const env = {
PORT: parseInt(process.env.PORT || '3000'),
GEMINI: {
API_KEY: process.env.GOOGLE_GEMINI_API_KEY || '',
MODEL_NAME: process.env.GOOGLE_GEMINI_MODEL || 'gemini-pro',
},
};
```
`throttler.config.ts` defines the rate limit of the API
```typescript
// throttler.config.ts
import { ThrottlerModule } from '@nestjs/throttler';
export const throttlerConfig = ThrottlerModule.forRoot([
{
ttl: 60000,
limit: 10,
},
]);
```
Each route allows ten requests in 60,000 milliseconds or 1 minute.
###Bootstrap the application
```typescript
// bootstrap.ts
export class Bootstrap {
private app: NestExpressApplication;
async initApp() {
this.app = await NestFactory.create(AppModule);
}
enableCors() {
this.app.enableCors();
}
setupMiddleware() {
this.app.use(express.json({ limit: '1000kb' }));
this.app.use(express.urlencoded({ extended: false }));
this.app.use(compression());
this.app.use(helmet());
}
setupGlobalPipe() {
this.app.useGlobalPipes(validateConfig);
}
async startApp() {
await this.app.listen(env.PORT);
}
setupSwagger() {
const config = new DocumentBuilder()
.setTitle('ESG Advisory Feedback with Langchain multiple chains and Gemini')
.setDescription('Integrate with Langchain to improve ESG advisory feebacking by prompt chaining')
.setVersion('1.0')
.addTag('Langchain, Gemini 1.5 Pro Model, Multiple Chains')
.build();
const document = SwaggerModule.createDocument(this.app, config);
SwaggerModule.setup('api', this.app, document);
}
}
```
Added a Bootstrap class to set up Swagger, middleware, global validation, CORS, and finally, application start.
```typescript
// main.ts
import { env } from '~configs/env.config';
import { Bootstrap } from '~core/bootstrap';
async function bootstrap() {
const bootstrap = new Bootstrap();
await bootstrap.initApp();
bootstrap.enableCors();
bootstrap.setupMiddleware();
bootstrap.setupGlobalPipe();
bootstrap.setupSwagger();
await bootstrap.startApp();
}
bootstrap()
.then(() => console.log(`The application starts successfully at port ${env.PORT}`))
.catch((error) => console.error(error));
```
The bootstrap function enabled CORS, registered middleware to the application, set up Swagger documentation, and validated payloads using a global pipe.
I have laid down the groundwork and the next step is to add an endpoint to receive payload for generating replies with prompt chaining.
###Define Feedback DTO
```typescript
// feedback.dto.ts
import { IsNotEmpty, IsString } from 'class-validator';
export class FeedbackDto {
@IsString()
@IsNotEmpty()
prompt: string;
}
```
`FeedbackDto` accepts a prompt, which is customer feedback.
###Construct Gemini Model
```typescript
// gemini.constant.ts
export const GEMINI_CHAT_MODEL = 'GEMINI_CHAT_MODEL';
```
```typescript
// gemini-chat-model.provider.ts
export const GeminiChatModelProvider: Provider<ChatGoogleGenerativeAI> = {
provide: GEMINI_CHAT_MODEL,
useFactory: () =>
new ChatGoogleGenerativeAI({
apiKey: env.GEMINI.API_KEY,
model: env.GEMINI.MODEL_NAME,
safetySettings: [
{
category: HarmCategory.HARM_CATEGORY_DANGEROUS_CONTENT,
threshold: HarmBlockThreshold.BLOCK_MEDIUM_AND_ABOVE,
},
{
category: HarmCategory.HARM_CATEGORY_HARASSMENT,
threshold: HarmBlockThreshold.BLOCK_MEDIUM_AND_ABOVE,
},
{
category: HarmCategory.HARM_CATEGORY_HATE_SPEECH,
threshold: HarmBlockThreshold.BLOCK_MEDIUM_AND_ABOVE,
},
{
category: HarmCategory.HARM_CATEGORY_SEXUALLY_EXPLICIT,
threshold: HarmBlockThreshold.BLOCK_MEDIUM_AND_ABOVE,
},
],
temperature: 0.5,
topK: 10,
topP: 0.5,
maxOutputTokens: 2048,
}),
};
```
`GeminiChatModelProvider` is a Gemini model that writes a short reply in the same language as the feedback.
###Implement Reply Service
```typescript
// customer-feedback.type.ts
export type CustomerFeedback = {
feedback: string;
};
```
```typescript
// advisory-feedback-prompt-chaining.service.ts
// Omit the import statements
@Injectable()
export class AdvisoryFeedbackPromptChainingService {
private readonly logger = new Logger(AdvisoryFeedbackPromptChainingService.name);
constructor(@Inject(GEMINI_CHAT_MODEL) private model: ChatGoogleGenerativeAI) {}
private createFindLanguageChain() {
const languageTemplate = `What is the language of this feedback?
When the feedback is written in Traditional Chinese, return Traditional Chinese. When the feedback is written in
Simplified Chinese, return Simplified Chinese.
Please give me the language name, and nothing else. Delete the trailing newline character
Feedback: {feedback}`;
const languagePrompt = PromptTemplate.fromTemplate<CustomerFeedback>(languageTemplate);
return languagePrompt.pipe(this.model).pipe(new StringOutputParser());
}
private createTopicChain() {
const topicTemplate = `What is the topic of this feedback?
Just the topic and explanation is not needed. Delete the trailing newline character
Feedback: {feedback}`;
const topicPrompt = PromptTemplate.fromTemplate<CustomerFeedback>(topicTemplate);
return topicPrompt.pipe(this.model).pipe(new StringOutputParser());
}
private createSentimentChain() {
const sentimentTemplate = `What is the sentiment of this feedback? No explaination is needed.
When the sentiment is positive, return 'POSITIVE', is neutral, return 'NEUTRAL', is negative, return 'NEGATIVE'.
Feedback: {feedback}`;
const sentimentPrompt = PromptTemplate.fromTemplate<CustomerFeedback>(sentimentTemplate);
return sentimentPrompt.pipe(this.model).pipe(new StringOutputParser());
}
async generateReply(feedback: string): Promise<string> {
try {
const chainMap = RunnableMap.from<CustomerFeedback>({
language: this.createFindLanguageChain(),
sentiment: this.createSentimentChain(),
topic: this.createTopicChain(),
feedback: ({ feedback }) => feedback,
});
const replyPrompt =
PromptTemplate.fromTemplate(`The customer wrote a {sentiment} feedback about {topic} in {language}. Feedback: {feedback}
Please give a short reply in the same language.`);
const combinedChain = RunnableSequence.from([chainMap, replyPrompt, this.model, new StringOutputParser()]);
const response = await combinedChain.invoke({
feedback,
});
this.logger.log(response);
return response;
} catch (ex) {
console.error(ex);
throw ex;
}
}
}
```
`AdvisoryFeedbackPromptChainingService` injects a chat model in the constructor.
- model - A chat model for a multi-turn conversation to generate a reply.
- createFindLanguageChain - a chain to identify the language of the feedback.
- createSentimentChain - a chain to determine the feedback's sentiment (POSITIVE, NEUTRAL, NEGATIVE).
- createTopicChain - a chain to determine the feedback topics.
- generateReply - this method executed multiple chains in parallel and the outputs became the inputs of the `replyPrompt`. Then, the combinedChain invoked the replyPrompt to generate replies in the same language based on sentiment and topics.
The process for generating replies ended by producing the text output from generateReply. The method asked questions concurrently and wrote a descriptive prompt for the LLM to draft a polite reply that addressed the needs of the customer.
```typescript
// advisory-feedback.service.ts
// Omit the import statements to save space
@Injectable()
export class AdvisoryFeedbackService {
constructor(private promptChainingService: AdvisoryFeedbackPromptChainingService) {}
generateReply(prompt: string): Promise<string> {
return this.promptChainingService.generateReply(prompt);
}
}
```
`AdvisoryFeedbackService` injects `AdvisoryFeedbackPromptChainingService` and constructs multiple chains to ask the chat model to generate a reply.
###Implement Advisory Feedback Controller
```typescript
// advisory-feedback.controller.ts
// Omit the import statements to save space
@Controller('esg-advisory-feedback')
export class AdvisoryFeedbackController {
constructor(private service: AdvisoryFeedbackService) {}
@Post()
generateReply(@Body() dto: FeedbackDto): Promise<string> {
return this.service.generateReply(dto.prompt);
}
}
```
The `AdvisoryFeedbackController` injects `AdvisoryFeedbackService` using Langchain and Gemini 1.5 Pro model. The endpoint invokes the method to generate a reply from the prompt.
- /esg-advisory-feedback - generate a reply from a prompt
###Module Registration
The `AdvisoryFeedbackModule` provides `AdvisoryFeedbackPromptChainingService`, `AdvisoryFeedbackService` and `GeminiChatModelProvider`. The module has one controller that is `AdvisoryFeedbackController`.
```typescript
// advisory-feedback.module.ts
// Omit the import statements due to brevity reason
@Module({
controllers: [AdvisoryFeedbackController],
providers: [GeminiChatModelProvider, AdvisoryFeedbackService, AdvisoryFeedbackPromptChainingService],
})
export class AdvisoryFeedbackModule {}
```
Import AdvisoryFeedbackModule into AppModule.
```typescript
// app.module.ts
@Module({
imports: [throttlerConfig, AdvisoryFeedbackModule],
controllers: [AppController],
providers: [
{
provide: APP_GUARD,
useClass: ThrottlerGuard,
},
],
})
export class AppModule {}
```
###Test the endpoints
I can test the endpoints with cURL, Postman or Swagger documentation after launching the application.
```bash
npm run start:dev
```
The URL of the Swagger documentation is http://localhost:3002/api.
In cURL
```bash
curl --location 'http://localhost:3002/esg-advisory-feedback' \
--header 'Content-Type: application/json' \
--data '{
"prompt": "Looking ahead, the needs of our customers will increasingly be defined by sustainable choices. ESG reporting through diginex has brought us uniformity, transparency and direction. It provides us with a framework to be able to demonstrate to all stakeholders - customers, employees, and investors - what we are doing and to be open and transparent."
}'
```
###Dockerize the application
```
// .dockerignore
.git
.gitignore
node_modules/
dist/
Dockerfile
.dockerignore
npm-debug.log
```
Create a `.dockerignore` file for Docker to ignore some files and directories.
```
// Dockerfile
# Use an official Node.js runtime as the base image
FROM node:20-alpine
# Set the working directory in the container
WORKDIR /app
# Copy package.json and package-lock.json to the working directory
COPY package*.json ./
# Install the dependencies
RUN npm install
# Copy the rest of the application code to the working directory
COPY . .
# Expose a port (if your application listens on a specific port)
EXPOSE 3002
# Define the command to run your application
CMD [ "npm", "run", "start:dev"]
```
I added the `Dockerfile` that installed the dependencies, built the NestJS application, and started it at port 3002.
```yaml
// docker-compose.yaml
version: '3.8'
services:
backend:
build:
context: .
dockerfile: Dockerfile
environment:
- PORT=${PORT}
- GOOGLE_GEMINI_API_KEY=${GOOGLE_GEMINI_API_KEY}
- GOOGLE_GEMINI_MODEL=${GOOGLE_GEMINI_MODEL}
ports:
- "${PORT}:${PORT}"
networks:
- ai
restart: unless-stopped
networks:
ai:
```
I added the `docker-compose.yaml` in the current folder, which was responsible for creating the NestJS application container.
###Launch the Docker application
```bash
docker-compose up
```
Navigate to http://localhost:3002/api to read and execute the API.
This concludes my blog post about using Langchain multiple chains and Gemini 1.5 Pro model to tackle generating replies regardless the written languages. Generating replies with multiple chains reduces the efforts that a writer needs to compose a polite reply to any customer. I only scratched the surface of Langchain and Gemini because Langchain integrates with many LLMs to create chatbots, RAG, and text embeddings applications. I hope you like the content and continue to follow my learning experience in Angular, NestJS, Generative AI, and other technologies.

Personalized recommendations appear before you even think of them, updates happen instantaneously, and interactions flow seamlessly. This captivating world is powered by real-time data, the lifeblood of modern applications.
But this power comes at a cost. The intricate [architecture behind real-time services](https://thenewstack.io/how-to-build-a-scalable-platform-architecture-for-real-time-data/) can make troubleshooting issues a nightmare. Organizations that rely on real-time data to deliver products and services face a critical challenge: ensuring data is delivered fresh and on time. Missing data or delays can cripple the user experience and demand resolutions within minutes, if not seconds.
This article delves into the world of real-time data challenges. We’ll explore the business settings where real-time data is king, highlighting the potential consequences of issues. Then I will introduce a novel approach that injects automation into the troubleshooting process, saving valuable time and resources, but most importantly mitigating the business impact when problems arise.
## Lags & Missing Data: The Hidden Disruptors Across Industries
Lags and missing data can be silent assassins, causing unseen disruptions that ripple through various industries. Let’s dig into the specific ways these issues can impact different business sectors.
### Financial markets
- **Trading:** In high-frequency trading, even milliseconds of delay can mean the difference between a profitable and losing trade. Real-time data on market movements is crucial for making informed trading decisions.
- **Fraud detection:** Real-time monitoring of transactions allows financial institutions to identify and prevent fraudulent activity as it happens. Delays in data can give fraudsters a window of opportunity.
- **Risk management:** Real-time data on market volatility, creditworthiness, and other factors helps businesses assess and manage risk effectively. Delays can lead to inaccurate risk assessments and potentially large losses.
### Supply chain management
- **Inventory management:** Real-time data on inventory levels helps businesses avoid stockouts and optimize inventory costs. Delays can lead to overstocking or understocking, impacting customer satisfaction and profitability.
- **Logistics and transportation:** Real-time tracking of shipments allows companies to optimize delivery routes, improve efficiency, and provide accurate delivery estimates to customers. Delays can disrupt logistics and lead to dissatisfied customers.
- **Demand forecasting:** Real-time data on customer behavior and sales trends allows businesses to forecast demand accurately. Delays can lead to inaccurate forecasts and production issues.
### Customer service
- **Live chat and phone support:** Real-time access to customer data allows support agents to personalize interactions and resolve issues quickly. Delays can lead to frustration and longer resolution times.
- **Social media monitoring:** Real-time tracking of customer sentiment on social media allows businesses to address concerns and build brand reputation. Delays can lead to negative feedback spreading before it’s addressed.
- **Personalization:** Real-time data on customer preferences allows businesses to personalize website experiences, product recommendations, and marketing campaigns. Delays can limit the effectiveness of these efforts.
###Manufacturing
- **Machine monitoring:** Real-time monitoring of machine performance allows for predictive maintenance, preventing costly downtime. Delays can lead to unexpected breakdowns and production delays.
- **Quality control:** Real-time data on product quality allows for immediate identification and correction of defects. Delays can lead to defective products reaching customers.

## The Delicate Dance: A Web of Services and Hidden Culprits
Modern user experiences that leverage real-time data rely on complex chains of interdependent services – a delicate dance of microservices, databases, messaging platforms, and virtualized compute infrastructure. A malfunction in any one element can create a ripple effect, impacting the freshness and availability of data for users. This translates to frustrating delays, lags, or even complete UX failures.
Let’s delve into the hidden culprits behind these issues and see how seemingly minor bottlenecks can snowball into major UX problems:
## Slowdown Domino with Degraded Microservice
- **Scenario:** A microservice responsible for product recommendations experiences high latency due to increased user traffic and internal performance degradation (e.g., memory leak, code inefficiency).
- **Impact 1:** The overloaded and degraded microservice takes significantly longer to process requests and respond to the database.
- **Impact 2:** The database, waiting for the slow microservice response, experiences delays in retrieving product information.
- **Impact 3:** Due to the degradation, the microservice might also have issues sending messages efficiently to the message queue. These messages contain updates on product availability, user preferences, or other relevant data for generating recommendations.
- **Impact 4:** Messages pile up in the queue due to slow processing by the microservice, causing delays in delivering updates to other microservices responsible for presenting information to the user.
- **Impact 5:** The cache, not receiving timely updates from the slow microservice and the message queue, relies on potentially outdated data.
- **User Impact:** Users experience significant delays in seeing product recommendations. The recommendations themselves might be inaccurate or irrelevant due to outdated data in the cache, hindering the user experience and potentially leading to missed sales opportunities. Additionally, users might see inconsistencies between product information displayed on different pages (due to some parts relying on the cache and others waiting for updates from the slow microservice).
## Message Queue Backup
- **Scenario:** A sudden spike in user activity overwhelms the message queue handling communication between microservices.
- **Impact 1:** Messages pile up in the queue, causing delays in communication between microservices.
- **Impact 2:** Downstream microservices waiting for messages experience delays in processing user actions.
- **Impact 3:** The cache, not receiving updates from slow microservices, might provide outdated information.
- **User Impact:** Users experience lags in various functionalities – for example, slow loading times for product pages, delayed updates in shopping carts, or sluggish responsiveness when performing actions.
## Cache Miss Cascade
- **Scenario:** A cache experiences a high rate of cache misses due to frequently changing data (e.g., real-time stock availability).
- **Impact 1:** The microservice needs to constantly retrieve data from the database, increasing the load on the database server.
- **Impact 2:** The database, overloaded with requests from the cache, experiences performance degradation.
- **Impact 3:** The slow database response times further contribute to cache misses, creating a feedback loop.
- **User Impact:** Users experience frequent delays as the system struggles to retrieve data for every request, leading to a sluggish and unresponsive user experience.
## Kubernetes Lag
- **Scenario:** A resource bottleneck occurs within the Kubernetes cluster, limiting the processing power available to microservices.
- **Impact 1:** Microservices experience slow response times due to limited resources.
- **Impact 2:** Delays in microservice communication and processing cascade throughout the service chain.
- **Impact 3:** The cache might become stale due to slow updates, and message queues could experience delays.
- **User Impact:** Users experience lags across various functionalities, from slow page loads and unresponsive buttons to delayed updates in real-time data like stock levels or live chat messages.
Even with advanced monitoring tools, pinpointing the root cause of these and other issues can be a [time-consuming detective hunt](https://www.causely.io/blog/devops-may-have-cheated-death-but-do-we-all-need-to-work-for-the-king-of-the-underworld/?utm_source=dev.to&utm_medium=referral&utm_campaign=real-time). The triage & troubleshooting process often requires a team effort, bringing together experts from various disciplines. Together, they sift through massive amounts of observability data – traces, metrics, logs, and the results of diagnostic tests – to piece together the evidence and draw the right conclusions so they can accurately determine the cause and effect. The speed and accuracy of the process is very much determined by the skills of the available resources when issues arise
Only when the root cause is understood can the responsible team make informed decisions to resolve the problem and restore reliable service.
## Transforming Incident Response: Automation of the Triage & Troubleshooting Process
Traditional methods of incident response, often relying on manual triage and troubleshooting, can be slow, inefficient, and prone to human error. This is where automation comes in, particularly with the advancements in Artificial Intelligence (AI). Specifically, a subfield of AI called [Causal AI](https://ssir.org/articles/entry/the_case_for_causal_ai) presents a revolutionary approach to transforming incident response.
Causal AI goes beyond correlation, directly revealing cause-and-effect relationships between incidents and their root causes. In an environment where services rely on real-time data and fast resolution is critical, Causal AI offers significant benefits:
- **Automated Triage:** Causal AI analyzes alerts and events to prioritize incidents based on severity and impact. It can also pinpoint the responsible teams, freeing resources from chasing false positives.
- **Machine Speed Root Cause Identification:** By analyzing causal relationships, Causal AI quickly identifies the root cause, enabling quicker remediation and minimizing damage.
- **Smarter Decisions:** A clear understanding of the causal chain empowers teams to make informed decisions for efficient incident resolution.
[Causely](https://www.causely.io/?utm_source=dev.to&utm_medium=referral&utm_campaign=real-time) is leading the way in applying Causal AI to incident response for modern cloud-native applications. Causely’s technology utilizes [causal reasoning](https://www.causely.io/blog/bridging-the-gap-between-observability-and-automation-with-causal-reasoning/?utm_source=dev.to&utm_medium=referral&utm_campaign=real-time) to automate triage and troubleshooting, significantly reducing resolution times and mitigating business impact. Additionally, Causal AI streamlines post-incident analysis by automatically documenting the causal chain.
Beyond reactive incident response, Causal AI offers proactive capabilities that focus on measures to reduce the probability of future incidents and service disruptions, through improved hygiene, predictions and “what if” analysis.
[The solution](https://www.causely.io/platform/?utm_source=dev.to&utm_medium=referral&utm_campaign=real-time) is built for the modern world that incorporates real-time data, applications that communicate synchronously and asynchronously, and leverage modern cloud building blocks (databases, caching, messaging & streaming platforms and Kubernetes).
This is just the beginning of the transformative impact Causal AI is having on incident response. As the technology evolves, we can expect even more advancements that will further streamline and strengthen organizations’ ability to continuously assure the reliability of applications.

1,883,442 | Swift 101: Collections Part II - Sets | Hola Mundo! Welcome to a new article in a series of Swift 101 notes 📝 I created these... | 27,019 | 2024-06-10T16:46:53 | https://dev.to/silviaespanagil/swift-101-collections-part-ii-sets-3i41 | swift, beginners, learning, mobile | #<h1> Hola Mundo! </h1>
<Enter>
Welcome to a new article in a series of [Swift 101 notes](https://dev.to/silviaespanagil/swift-101-getting-into-ios-development-gji) 📝 I created these notes while learning the language and decided to share them because, why not?
If you're new to Swift or interested in learning more about this language, I invite you to follow my series! 🙊
Last week I shared a post with [the first part of collections which was arrays](https://dev.to/silviaespanagil/swift-101-collections-part-i-arrays-2a52). Initially, I thought I would cover collections in two parts, but who wants to read that much in one go 🙅🏽♀️? So, this will be the second part of what will likely be four parts. Next week, I'll share and try to cover Tuples and Dictionaries.
So, let's get to it 💪!
___
As a quick refresher [from last week's chapter](https://dev.to/silviaespanagil/swift-101-collections-part-i-arrays-2a52), "Collections" are types that store multiple values. They arrange all those values in certain ways so we can access them in the future.
Think of it like a fruit basket with many fruits in it. Similarly, arrays in Swift store multiple values of the same type in an ordered list, like a line of apples, oranges, and bananas neatly arranged in your basket 🍎🍊🍌
There are many types of Collections, like Arrays which we already discussed. Today I want to share about ✨**Sets**✨.
<Enter>
___
###Sets
<Enter>
Sets, like arrays and other collections, allow us to store many elements **of the same type** in a variable. However, sets store the values without any particular order.
The main characteristics of sets are:
- **Order:** Sets **do not have a defined order**; they store values in the way that Swift thinks is most effective.
- **Elements can’t repeat itself**: On sets all element values must be unique. If there’s a duplicated one it will be ignored.
<Enter>
```
swift
let colors = Set(["red", "green", "blue"])
print(colors)
// Output: ["red", "blue", "green"]
let colors2 = Set(["red", "green", "blue", "green"])
print(colors2)
// Output: ["green", "red", "blue"]
```
To declare an empty set you specify the type of elements it will hold using the Set keyword followed by the type in angle brackets:
`var mySet = Set<Int>()`
You can also declare a set with initial values. Swift will infer the type of the set based on the type of the initial values:
`var mySet: Set = [1, 2, 3, 4, 5]`
or, specifying the type explicitly:
`var mySet: Set<Int> = [1, 2, 3, 4, 5]`
🔥 Remember that Sets do not maintain the order of elements and that repeated elements will be ignored 🔥
<Enter>

###Sets managing: accessing values and methods
####Accessing sets values
Since sets have no specific order, we must access their elements using loops or by using their methods and properties.
##### **Iterations on sets**
To iterate over a set, we can use the `for-in` loop. This allows us to access each element in the set one by one.
```swift
let fellowshipMembers: Set = ["Frodo", "Aragorn", "Gandalf", "Legolas", "Gimli", "Merry", "Pippin", "Boromir"]
for member in fellowshipMembers {
print(member)
}
// Output: This will print all the members
```
🧐 Remember that Sets do not maintain the order of elements 🧐
___
#### Set methods and properties
Swift also provides us with some methods and properties that we may use and that can be useful for different operations.
Let's see the most used:
####`.count`
This property counts how many elements are inside our Set.
```swift
let letter: Set = ["w", "e", "f", "o", "x"]
print(letter.count)
// Output: 5
```
####`.insert()`
This method allows us to add new elements to our Set.
``` swift
var groceryList: Set = ["Onions", "Apples", "Pasta"]
groceryList.insert("Bread")
print(groceryList)
// Possible output: ["Pasta", "Onions", "Bread", "Apples"]
```
####`.remove()`
Allows us to remove an element from the set
```swift
var groceryList: Set = ["Onions", "Apples", "Pasta"]
groceryList.remove("Pasta")
print(groceryList)
// Possible output: ["Onions", "Apples"]
```
####`.removeAll()`
This method empties the Set of all its values.
```swift
var groceryList: Set = ["Onions", "Apples", "Pasta"]
groceryList.removeAll()
print(groceryList)
// Output: []
```
####`.contains(_:)`
This method checks if the Set contains a specific element.
```swift
var numbers: Set = [3, 63, 27]
let containsTwentySeven = numbers.contains(27)
print(containsTwentySeven)
// Output: true
```
####`.isEmpty`
This property checks if the Set is empty and returns a boolean result.
```swift
var numbers = [3, 63, 27]
print(numbers.isEmpty) // Output: false
```
###Sets operations
####`.union(_:)`
This method returns a new set containing all elements from both sets. Since sets cannot have duplicate values, any value that appears in both sets will only appear once in the union.
```swift
let fellowshipOfTheRing: Set = ["Frodo", "Sam", "Merry", "Pippin", "Aragorn", "Legolas", "Gimli", "Boromir", "Gandalf"]
let charactersInRohan: Set = ["Aragorn", "Legolas", "Gimli", "Gandalf", "Eomer", "Eowyn", "Theoden"]
let allCharacters = fellowshipOfTheRing.union(charactersInRohan)
print(allCharacters)
// Possible output: ["Sam", "Merry", "Pippin", "Legolas", "Aragorn", "Gimli", "Eowyn", "Frodo", "Theoden", "Eomer", "Boromir", "Gandalf"]
```
####`.intersection(_:)`
This method returns a new set with only the elements common to both sets.
```swift
let fellowshipOfTheRing: Set = ["Frodo", "Sam", "Merry", "Pippin", "Aragorn", "Legolas", "Gimli", "Boromir", "Gandalf"]
let charactersInRohan: Set = ["Aragorn", "Legolas", "Gimli", "Gandalf", "Eomer", "Eowyn", "Theoden"]
let commonCharacters = fellowshipOfTheRing.intersection(charactersInRohan)
print(commonCharacters)
// Possible output: ["Aragorn", "Legolas", "Gandalf", "Gimli"]
```
####`.subtracting(_:)`
This method returns a new set with the elements of the first set that **are not** in the second set.
```swift
let fellowshipOfTheRing: Set = ["Frodo", "Sam", "Merry", "Pippin", "Aragorn", "Legolas", "Gimli", "Boromir", "Gandalf"]
let charactersInRohan: Set = ["Aragorn", "Legolas", "Gimli", "Gandalf", "Eomer", "Eowyn", "Theoden"]
let uniqueToFellowship = fellowshipOfTheRing.subtracting(charactersInRohan)
print(uniqueToFellowship)
// Possible output:["Boromir", "Frodo", "Pippin", "Sam", "Merry"]
```
####`.symmetricDifference(_:)`
This method returns a new set with elements that are in either of the sets **but not in both.**
```swift
let fellowshipOfTheRing: Set = ["Frodo", "Sam", "Merry", "Pippin", "Aragorn", "Legolas", "Gimli", "Boromir", "Gandalf"]
let charactersInRohan: Set = ["Aragorn", "Legolas", "Gimli", "Gandalf", "Eomer", "Eowyn", "Theoden"]
let differentCharacters = fellowshipOfTheRing.symmetricDifference(charactersInRohan)
print(differentCharacters)
// Possible output:["Pippin", "Boromir", "Eomer", "Merry", "Sam", "Frodo", "Eowyn", "Theoden"]
```

1,883,529 | Empowering Farmers with Livestock Match | Introduction Purpose of the Project: Livestock Match is an innovative platform designed to connect... | 0 | 2024-06-10T16:33:56 | https://dev.to/lawrence_denhere/empowering-farmers-with-livestock-match-4d81 | <u>**Introduction**</u>
**Purpose of the Project**: Livestock Match is an innovative platform designed to connect livestock farmers with quality breeding stock, streamlining the process and enhancing the sustainability of livestock operations.
<u>**Project Role and Timeline:**</u>
Since I worked solo on this project, I took on every role from ideation to deployment. The project timeline was as follows:
June 6, 2024: Project kickoff
June 10, 2024: Midpoint review and adjustments
June 13, 2024: Final presentation and deployment
**Target Audience:** The platform is tailored for livestock farmers seeking to improve their breeding practices and buyers looking for reliable and transparent transactions.
**Personal Focus:** My primary focus was on developing a user-friendly platform that simplifies the breeding stock selection process, provides essential market insights, and ensures secure transactions.
<u>**Inspiration Behind Livestock Match**</u>
Growing up surrounded by the sights, sounds, and smells of the farm, my passion for livestock husbandry was ignited at an early age. From the gentle lowing of cattle to the comforting warmth of the barn, every aspect of farm life captivated my imagination and instilled within me a deep appreciation for the symbiotic relationship between humans and animals.
As I witnessed the joys and challenges of farming firsthand, I became acutely aware of the critical role that breeding practices play in the success and sustainability of livestock operations. Despite the wealth of knowledge and experience accumulated over generations, I recognized the need for a modern solution that would streamline the process of connecting farmers with quality breeding stock.
Driven by my lifelong love for farming and a desire to contribute meaningfully to the agricultural community, I embarked on a journey to create Livestock Match. Rooted in the values of innovation, collaboration, and stewardship, Livestock Match is more than just a platform—it's a testament to the enduring bond between farmers and their animals. With Livestock Match, my goal is to empower farmers with the tools and resources they need to make informed breeding decisions, improve the health and productivity of their herds, and foster a more sustainable future for agriculture.
<u>**Project Accomplishments**</u>
**Project Outcome**: Livestock Match successfully connects farmers with buyers, offering a user-friendly platform with features like real-time market data, secure transactions, and detailed animal profiles.
<u>**Architecture Diagram**</u>:
<u>**Technologies Used**</u>:
**Frontend**: HTML5, CSS3, JavaScript (React) - React was chosen for its component-based architecture, which allowed for a modular and maintainable codebase.
**Backend**: Python, Django - Django provided a robust framework for developing the backend, ensuring security and scalability.
**Database**: PostgreSQL - Chosen for its reliability and performance in handling large datasets.
**APIs**: Twilio API for SMS notifications, Stripe API for secure payment processing - These APIs added essential functionality for user communication and secure payments.
<u>**Key Features**</u>:
**User Profiles**: Farmers can create detailed profiles for their livestock, including images, health records, and pricing.
**Market Insights**: Real-time data on market trends and pricing helps users make informed decisions.
**Secure Transactions**: Integrated payment processing ensures secure and seamless transactions between buyers and sellers.
<u>**Technical Challenge**</u>
One of the most daunting technical challenges I encountered while developing Livestock Match was integrating a secure and reliable payment processing system. From the outset, it was clear that ensuring secure transactions was paramount to building trust with users and maintaining the platform’s integrity. After evaluating several options, I decided to implement the Stripe API due to its robust security features and comprehensive documentation. The integration process involved setting up a Stripe account and configuring the API keys, which was straightforward. However, embedding the Stripe checkout process into the React frontend posed significant difficulties. I had to ensure that the user experience was seamless and that sensitive data was securely handled. On the backend, I implemented Django to manage transactions and ensure data integrity. Extensive testing was crucial, as I needed to identify and resolve any issues that could potentially compromise security or user experience. During testing, I encountered problems with handling webhook events, which required careful debugging and consultation with Stripe’s support resources. Ultimately, overcoming these challenges not only enhanced my technical skills but also reinforced the importance of thorough testing and attention to security in web development. The successful integration of Stripe provided users with a secure and efficient payment process, greatly enhancing the platform's functionality and user trust.
<u>**Learnings**</u>
<u>**Technical Takeaways**</u>:
**API Integration**: The importance of selecting the right APIs and understanding their documentation thoroughly.
**Security**: Ensuring secure transactions is paramount, requiring careful handling of user data and robust encryption methods.
<u>**Personal Growth**:</u>
**Full-Stack Development**: This project honed my skills in both frontend and backend development, allowing me to see the bigger picture of how different components interact.
**Problem-Solving**: Overcoming technical challenges reinforced my ability to think critically and find effective solutions.
**Future Directions**: This project has deepened my interest in developing solutions for the agricultural sector. Moving forward, I plan to explore more advanced features like predictive analytics for market trends and enhanced user engagement tools.
<u>**About Me**</u>
I am a passionate software engineer dedicated to creating technology solutions that address real-world problems. My experience spans full-stack development, with a focus on user-centric design and secure application architecture.

1,883,525 | Choosing Between SQL and NoSQL | Introduction to SQL and NoSQL Databases Databases are essential for storing and managing... | 0 | 2024-06-10T16:23:48 | https://dev.to/adrianbailador/choosing-between-sql-and-nosql-n9i | sql, nosql, database, webdev | ## Introduction to SQL and NoSQL Databases
Databases are essential for storing and managing data in modern applications. There are two major categories: **SQL** and **NoSQL**. The choice between these two depends on various factors, including the type of data, the nature of the queries, and the scalability needs.
## SQL Databases
SQL databases are relational database management systems (RDBMS) that use structured query languages (SQL) to define and manipulate data. They are divided into two main types:
1. **Row-Based**
2. **Column-Based**
### Row-Based Databases
Row-based databases store data for an entity in a row and its attributes in columns. Examples include MySQL, PostgreSQL, and SQLite.
**Advantages**:
- **Data Normalisation**: Avoids data duplication.
- **Transactions**: Ensure that a set of operations either complete successfully or fail completely.
- **Stability and Consistency**: Suitable for applications with well-defined data structures and frequent transactions.
**Disadvantages**:
- **Complex Queries**: Joins necessary for normalisation can complicate queries and affect performance.
- **Not Optimised for Analysis**: Analytical queries can be slow as they require reading many rows.
### Column-Based Databases
Column-based databases store data for each column together. Examples include Google BigTable and Cassandra.
**Advantages**:
- **Fast Analytical Queries**: Ideal for workloads that only need a few attributes.
- **Read Optimisation**: Store and read data from specific columns, improving performance for analytical queries.
**Disadvantages**:
- **Slow Write Operations**: Updating data in separate columns can be less efficient.
- **Complex Transactions**: Less suitable for applications requiring frequent transactions and immediate consistency.
---
## Example of SQL Table Structure
### Row-Based SQL (Example of Product and Seller Tables)
```plaintext
Product Table
--------------
| ID | Title | Price | SellerID |
|----|-----------|-------|----------|
| 1 | Product A | 10.00 | 1 |
| 2 | Product B | 20.00 | 2 |
Seller Table
-------------
| ID | Name |
|----|-----------|
| 1 | Seller 1 |
| 2 | Seller 2 |
```
### Column-Based SQL (Example of Product Table)
```plaintext
Product Columns
----------------
ID | Title
1 | Product A
2 | Product B
Price
------
ID | Price
1 | 10.00
2 | 20.00
SellerID
---------
ID | SellerID
1 | 1
2 | 2
```
## NoSQL Databases
NoSQL databases are database management systems that do not rely on the table and relational structure of SQL. The most common types are:
1. **Document Databases**
2. **Streaming Databases**
### Document Databases
Document databases store data in document formats, typically JSON. Examples include MongoDB and CouchDB.
**Advantages**:
- **Flexible Data Modelling**: Data can be stored in documents without a predefined structure.
- **Horizontal Scalability**: Can be easily distributed across multiple servers.
- **Fast Reads**: Ideal for applications requiring many fast reads and few writes.
**Disadvantages**:
- **Data Denormalisation**: Can lead to data duplication.
- **Eventual Consistency**: Do not always guarantee immediate data consistency, which can be an issue for certain applications.
### Streaming Databases
Used to handle real-time data streams. Examples include Kafka and Amazon SQS.
**Advantages**:
- **Handling Large Volumes of Real-Time Data**: Suitable for applications needing real-time data processing.
- **Decoupling Producers and Consumers**: Simplifies architecture by allowing producers to remain unaware of consumers.
**Disadvantages**:
- **Implementation Complexity**: Requires more complex infrastructure and careful message management.
## Example of NoSQL Document Structure
```json
{
"product_id": 1,
"title": "Product A",
"price": 10.00,
"seller": {
"id": 1,
"name": "Seller 1"
}
}
```
## Deciding Between SQL and NoSQL
**When to Use SQL**:
- You need transactional consistency.
- You have well-structured data and complex relationships.
- You prefer a rigid, normalised data model.
**When to Use NoSQL**:
- You need horizontal scalability.
- You have semi-structured or unstructured data.
- You require high read rates and low latency.
## Summary
- **SQL is Ideal For**: Applications requiring transactional consistency, well-defined data structures, and normalisation.
- **NoSQL is Ideal For**: Applications needing flexible data modelling, high horizontal scalability, and fast reads with few writes.
In conclusion, the choice between SQL and NoSQL depends on your specific data, performance, and scalability needs. SQL is ideal for transactional and structured applications, while NoSQL is more suitable for flexible and scalable applications. | adrianbailador |
1,841,650 | How To Create an NPM Package For React Native? | Introduction In the realm of React Native development, the ability to create and share... | 0 | 2024-06-10T16:22:51 | https://dev.to/amitkumar13/how-to-create-an-npm-package-for-react-native-4bkj | reactnative, react, npm, package | ## Introduction
In the realm of React Native development, the ability to create and share custom npm packages can significantly streamline workflows and enhance code reusability. This article serves as a comprehensive guide to help you create your own npm package tailored for React Native projects.
_Today, I'll delve into the intricacies of creating a custom npm package and uploading it to the npm store/registry, empowering you to streamline your development process and leverage the collective power of the developer community._
## Requirements for creating npm package
Before you begin creating your npm package, make sure you have the following prerequisites installed and set up on your system:
**1). GitHub Account:** Having a GitHub account is essential as it provides version control for your codebase and facilitates collaboration with other developers. You can host your package's source code on GitHub, making it accessible to a wider audience and allowing for community contributions and feedback.
**2). NPM Account:** You'll need an NPM account to publish your package to the NPM registry, making it available for others to install and use in their projects. Creating an NPM account is free and straightforward, requiring only basic information such as your email address and a username.
**3). Knowledge of React Native:** A solid understanding of React Native is crucial for developing components or utilities that integrate seamlessly with React Native projects. This includes knowledge of React Native's component lifecycle, styling, navigation, state management, and platform-specific considerations.
**4). Knowledge of TypeScript:** TypeScript is increasingly popular in the JavaScript ecosystem, offering static typing and enhanced code readability. Familiarity with TypeScript is beneficial when creating npm packages, especially if you want to provide type definitions for your package's API, improving developer experience and code reliability.
## What steps should be taken prior to developing a custom package?
Ensure that there are no existing similar packages already available or published before embarking on creating a custom package. Search platforms like Git or npm to identify any pre-existing packages of a similar nature.
## Create a new project
```
npx react-native init CustomButton
```
## Create a custom Button
Okay, let's create a custom button component
```
// File: src/components/CustomButton.js
import React from 'react';
import { TouchableOpacity, Text, StyleSheet } from 'react-native';
const CustomButton = ({ title, onPress }) => {
return (
<TouchableOpacity style={styles.button} onPress={onPress}>
<Text style={styles.buttonText}>{title}</Text>
</TouchableOpacity>
);
};
const styles = StyleSheet.create({
button: {
backgroundColor: '#007bff',
padding: 10,
borderRadius: 5,
},
buttonText: {
color: '#fff',
fontSize: 16,
fontWeight: 'bold',
textAlign: 'center',
},
});
export default CustomButton;
```
## Let's start with creating NPM package
First, create a new folder anywhere in the computer. Then, copy the "src" folder or any necessary files or folders that your component requires into this new folder. Inside the folder do the following command
Your final package.json look like this
> Note: Make sure to mention any other packages that your custom component relies on in the dependencies section of the `package.json` file.
```
{
"dependencies": {
"react": "18.2.0",
"react-native": "0.72.3",
"react-native-other-lib": "^2.2.0"
}
}
```
> If your custom component does not use any other packages, your package.json would look like this:
```
{
"dependencies": {
"react": "18.2.0",
"react-native": "0.72.3"
}
}
```
## Publishing Your Package
Open the terminal go to your project directory(same directory the your paste the scr folder) and Run the below command for npm login. To publish your package to npm, log in to your npm account using:
```
npm login
```
Then, publish your package with:
```
npm version 1.0.5 // must be unique version name
```
```
npm publish --access public
```
Your package is now published and available for others to install and use in their React Native projects.

1,883,451 | Shopify’s product overhaul: 2,000 variants, new GraphQL mutations, and a farewell to REST | Shopify’s 2024 Winter Editions focused on improving the foundations of the platform. And what is more... | 0 | 2024-06-10T16:18:36 | https://gadget.dev/blog/shopifys-product-overhaul-2000-variants-new-graphql-mutations-and-a-farewell-to-rest | shopify, webdev, graphql, restapi | [Shopify’s 2024 Winter Editions](https://www.shopify.com/ca/editions/winter2024) focused on improving the foundations of the platform. And what is more foundational to ecommerce than products?
Shopify announced one major change to how products are going to be handled in the platform going forward, which is accompanied by a bunch of changes to the underlying product APIs.
As always, that means many of these changes will affect developers. So let’s dig into what’s different.
## 100 → 2,000 product variants
At long last, Shopify has finally chosen to increase the product variant limit to 2,000 variants. This is great news for both developers and merchants, as it shifts variant management to Shopify’s infrastructure, so merchants no longer require custom applications to get around the 100 variant limit.
Merchants selling products that naturally have many different combinations and options, such as sizes, colors, and styles, will massively benefit from this limit increase.
The 2,000 variant limit isn’t live for production stores yet, but that doesn’t mean Shopify Partner developers can’t start testing out the changes on a development store.
To start testing the 2,000 variant limit:
- Create a new development store
- Select the Extended Variants developer preview
> **Note:** [Shopify’s documentation](https://shopify.dev/docs/api/release-notes/developer-previews#increased-variants-developer-preview) calls this preview the Increased Variants developer preview, instead of the Extended Variants naming displayed in the Partners dashboard when creating a new dev store.
Once your new development store is created, you can add up to 2,000 variants _per product_ by adding multiple product options as you normally would. Clothing options are a good place to start when generating test data.
For example, you could create a shirt product that comes in multiple different colors, has a range of different sizes, and has multiple different styles, for example, crew neck, v-neck, henley, and long-sleeved versions. Immediately, by offering 10 colors, 6 sizes, and 6 styles, you’ve created 360 possible variants (10 x 6 x 6) of this single product, which wouldn’t have worked with Shopify’s old 100 variant limit!
All of these variants will be visible as options on the product page in the storefront without any additional changes being required. No changes to Liquid or theme app extensions necessary.
Note: When adding a large number of variants, some additional loading is required on product pages in the admin. This will not be the case on the storefront itself.
Shopify is currently working with select partners to adopt this change in the variant limit and will be rolling this variant increase out across 2024.
## Updates for merchandising additional variants
With this increase in variants, merchants will also need to be able to properly merchandize all of the different variants and options that now exist for a single product. They may require dedicated URLs and SEO tags for product options, and certain product options or variants may need to be added to collections that are part of targeted marketing or discount campaigns.
Shopify has launched the [Combined Listings app](https://www.shopify.com/ca/enterprise/blog/combined-listings) to help display these additional variants in the storefront. It allows for flexibility in listing different options separately and provides proper SEO support for individual options and variants.
Available for Plus merchants only, this app allows merchants to [create child products under a single parent product](https://shopify.dev/docs/apps/build/product-merchandising/combined-listings), ensuring that each child has its own dedicated URL, media carousel, and description, while still being included as an option on a single product page.
This means that merchants can take full advantage of the additional variant limit without sacrificing their SEO strategies or losing the flexibility required by some product options.
## Product and variant API updates
In addition to the variant limit increasing, the product endpoints and data models are getting an overhaul as well. In version `2024-01`, the `/product` and `/variant` endpoints will be [deprecated in the REST Admin API](https://shopify.dev/docs/apps/build/graphql/migrate/new-product-model#whats-changing).
Additionally, the Shopify product data model and GraphQL Admin API are getting an overhaul, with additional fields and mutations being added allowing for bulk changes to product data.
Of particular interest, there is going to be a `productSet` mutation added that allows for product information to be [pushed in bulk from external sources](https://shopify.dev/docs/apps/build/graphql/migrate/new-product-model#database-sync-workflow), such as ERPs, to Shopify. Product options are also being elevated to first-class entities in the data model, which means that there will be a set of new mutations and fields for manipulating product option data.
You can [read Shopify’s documentation](https://shopify.dev/docs/apps/build/graphql/migrate/new-product-model/api-updates) to get all the details on the API changes for the updated product model. | gadget |

I don't want to make this a habit, but I guess it's been so busy these past two weeks that I didn't want to bother writing a whole post last week.
We've been focusing on getting our v0 (aka alpha version) out so that investors and such can start testing the app.
To generally cover what we've gotten done:
- iOS app is out on Test Flight
- revamped prompts
- speech to text
- two new architectures/prompts beyond what we had before
- a chat history sidebar
- selection of the architectures
- message limits
- a bunch of other small improvements/bugfixes
Generally, I've been working with my fellow prompt engineer and the others in the product team to get the prompts to do what we want, as has been the goal for the past 3 months. I believe I mentioned last time that we were transitioning from using fine-tune data to using just prompts for now. We need more resources to do fine-tune.
That being said, I also designed a script to get two AI models to talk to each other in a loop until the conversation naturally finishes. This was mostly to test that our prompts are adequate, but I can also take them and adapt them to fine-tune data. But the major issue is that it costs a lot and I'm actually not sure if it's generally better in terms of quality of the conversations.
Anyway, another thing we're considering is the fact that there's no chain-of-thought reasoning possible for our app. We are designing it so that the bot gives the shortest, most concise lines of questioning, which disallows for it to reason for the previous context. This causes the bot to follow the prompt and goals that we laid out a little too rigidly instead of following a natural flow. So to mitigate this, I'm thinking of designing a two-step process where it will take a long-winded response with chain-of-thought reasoning, then reduce that down to a singular question. This way, it can follow its own logic better.
So that's what's happened so far. Hopefully it turns out for the better. Until next time, cheers. | armantark |

1,883,446 | iOS or Android? Picking the Ideal Platform for Your App Development Journey | When comparing iOS and Android app development, it can be difficult to decide which platform is right... | 0 | 2024-06-10T16:13:03 | https://dev.to/jackwil77516601/ios-or-android-picking-the-ideal-platform-for-your-app-development-journey-4ol7 | mobile, hire, hireappdev, android | When comparing iOS and Android app development, it can be difficult to decide which platform is right for you. You don’t know whether to choose iOS or Android. This choice is what separates a would-be app developer from a successful entrepreneur — it can be tough to choose the correct one; however, not being able to select rightly could prevent you from succeeding. It’s challenging, guys. For example: an ambitious startup developed its first app on iOS because they didn’t realize that most of their target audience uses Android devices. Now they’re gun-shy about reinvesting in [mobile app development](https://hirefullstackdeveloperindia.com/hire-mobile-app-developers/) companies and worry they’ll never hit it big in this cutthroat market.
**Understanding the Differences between iOS and Android App Development**:
If you want to create a mobile app, one of your first choices will be whether to build for iOS or Android.
It’s not just about picking between Apple’s beautiful design aesthetics and Google’s flexible open-source platform.
**Different Programming Languages:**
When it comes to writing code for apps on each operating system, iOS apps are mainly written in Swift or Objective-C, while Android uses Java (or Kotlin, which was introduced by Google as an official language for the platform in 2017).
Kotlin has a more modern syntax than Java and tends to be easier on developers’ eyes.
**Varying Development Tools:**
The Integrated Development Environments (IDEs) used with each platform also have some differences; Xcode is the IDE for iOS while Android Studio is used for creating Android apps.
Xcode has features like live rendering directly within its interface but only runs on Macs. On the other hand, Android Studio works across multiple operating systems including Windows and Linux, powered by IntelliJ IDEA tools from JetBrains.
**Divergent Design Considerations:**
iOS follows Human Interface Guidelines that prioritize simplicity over flexibility with a focus on user experience, whereas the Material Design principles guiding Android app designs prioritize adaptability across diverse mobile devices even if this means slightly complex interfaces.
**Brief Comparison Summary:**
* Programming languages – Kotlin/Java(Swift/Objective C(iOS))
* IDEs employed – Andriod Studio(Android) against XCode(iOS)
* Last but not least important are design considerations each follow – Material Designs(Andriod), Human Interface Guidelines (iOs).
Now that we’ve outlined these differences more clearly, think about your specific project needs when considering which platform may align best with them.
**The Advantages of Creating iOS Apps:**
[iOS application development](https://hirefullstackdeveloperindia.com/hire-ios-developers/) has many advantages in the field of mobile application building that can greatly contribute to its success.
**A Greater Market Share with Apple Devices (iOS Apps):**
Devices like iPhones and iPads are very much loved all over the world, thus this provides a wider market share for your app hence increasing its reach and influence.
In some rich countries like the United States or Europe where people have huge purchasing power; it would be more appropriate to create an iPhone/iPad app because there are more iOS users among them (Refer below).
**Increased Monetization Opportunities on The Apple App Store:**
All iOS applications are hosted exclusively on the Apple App Store. According to research, it has been found that it earns more than the Google Play store by 85% or more.
This shows that there is an increased chance of making money through paid downloads and in-app purchases particularly when we consider that Apple users tend to be more involved than those using other platforms.
Further to this point is how strict their quality control measures are which only allow high-quality apps into the market thus reducing competition against bad ones.
**Predictable User Experience Across all IOS Devices:**
Updates are continuously made in all iPhone models up to the current one using the latest iOS software development kits (SDKs) that is why they have similar user interfaces (UI).
Through this uniformity, not only can mobile applications be designed for iOS but it also allows testing them more efficiently too.
The reason behind this is because developers do not have to worry about different screen sizes or OS versions on Android phones which may cause compatibility problems while working on an app.
Faster Time-to-Market With Fewer Device Fragmentation Issues.
Unlike android application development where there can be many types of devices with various features ,iOS generally uses integrated development environments and has less device fragmentation concerns since there are few apple devices available.
Android vs. iOS will always be a topic of debate.
Therefore, businesses can simplify their testing phase hence reducing time-to-market which gives them ability to rapidly introduce new services and respond promptly to changing customer needs.

1,883,441 | Securing the Build: Addressing Cairo Compiler Risks in StarkNet | The Cairo compiler is currently under development, which introduces potential security concerns. This... | 0 | 2024-06-10T16:06:19 | https://dev.to/pen_e58d9dbc52acdf766423e/securing-the-build-addressing-cairo-compiler-risks-in-starknet-3m2i | straknet, sierre, cairo, smartcontract | The Cairo compiler is currently under development, which introduces potential security concerns. This is mainly due to undiscovered bugs that could hypothetically arise during the compilation of Cairo programs. These unknown vulnerabilities can be avoided by leveraging a mature and tested compilation process.
**Why Sierra?**
Sierra, which stands for "Secure Integrated Relocatable Engine for Efficiency Automation," is a framework that provides a more stable intermediate representation for compiler audits and gas optimization. Sierra acts as an intermediary between the high-level Cairo language and the low-level execution environment.
By compiling Cairo code into Sierra, developers can perform audits and optimizations that are less susceptible to vulnerabilities introduced by Cairo compilers.
Sierra's maturity and stability provide a secure foundation for building and analyzing smart contracts, lowering the probability of introducing vulnerabilities produced by compilation artifacts.
**Enhancing Sierre Development with Debugging and Analysis
**
While the Universal Sierre Compiler (USC) serves as a stable intermediate representation, it's crucial to integrate debugging, performance analysis, and simulation analysis throughout the development lifecycle.
This proactive approach helps to:
Mitigate Potential Vulnerabilities: By proactively identifying and addressing issues early, these practices significantly reduce the risk of vulnerabilities sneaking into production code.
Optimize Performance: Performance analysis helps developers pinpoint bottlenecks and optimize code for efficiency, leading to faster and more cost-effective smart contracts.
Facilitate Communication: Regular communication within the StarkNet community is essential. Sharing findings from debugging and analysis can benefit the entire ecosystem by raising awareness of potential issues and fostering collaboration on solutions.
**Benefits of Sierre**
Compiler stability: Sierre provides a more stable compilation,reducing the risk of introducing compilation bugs, by using a mature and stable compiler.
Audit and optimisation: developers can utilise Sierre compiler for compiler -related audits and gas optimisation, ensuring their smart contracts are both secure and efficiant.
Community support: Due to the wide STARKNET community ecosystem developers can benifit from community scrutiny improvement and shared developments.
As StarkNet rapidly evolves,secure and optimized development will be a core focus for building robust smart contracts. By leveraging Sierre and best practices like debugging and analysis, developers can contribute to a secure and thriving StarkNet ecosystem. | pen_e58d9dbc52acdf766423e |
1,883,370 | Why Django + HTMX + Alpine.js is a better fit for content-driven sites than a JavaScript framework | When it comes to building a standard content-driven website, the choice of technology stack can... | 0 | 2024-06-10T16:04:42 | https://dev.to/documendous/why-django-htmx-alpinejs-is-a-better-fit-for-content-driven-sites-than-a-javascript-framework-2am7 | When it comes to building a standard content-driven website, the choice of technology stack can greatly influence the development process and the end result.
While modern JavaScript frameworks like Angular and React offer powerful features, they are usually not the best fit for every commercial and content-related project. Instead, opting for a server-side framework like Django, complemented with HTMX and Alpine.js for frontend functionality, can provide numerous benefits.
Here’s why:
**1. Simplicity and Ease of Use**
_Angular and React:_
- Both frameworks are powerful for frontend functionality but come with a steep learning curve.
- They require understanding complex concepts such as state management, component lifecycle, and JSX (in the case of React). Vast state management is almost never required unless you are building a live-action game or a true web application like a real-time stock trading platform.
- Setting up a project can be cumbersome, involving multiple configurations and dependencies.
_Django with HTMX and Alpine.js:_
- Django is known for its simplicity and “batteries-included” philosophy, providing tools and libraries needed for common tasks right out of the box.
- HTMX and Alpine.js are lightweight libraries that are easy to learn and integrate, allowing for rapid development without extensive boilerplate code.
- The combination of Django, HTMX, and Alpine.js provides a straightforward development experience, making it easier for developers to focus on delivering features.
**2. Performance and SEO**
_Angular and React:_
- Client-side rendering (CSR) can lead to slower initial page loads because the browser needs to download and execute JavaScript before rendering content.
- SEO can be challenging with CSR as search engine crawlers may struggle to index dynamically generated content, although this can be mitigated with server-side rendering (SSR), but it adds complexity.
_Django with HTMX and Alpine.js:_
- Django delivers server-rendered HTML, ensuring faster initial page loads since the browser receives fully formed HTML from the server.
- SEO is more straightforward with server-rendered content, as search engine crawlers can easily index the pages without additional configurations or workarounds.
- HTMX allows for dynamic content loading without a full page reload, improving user experience while maintaining the benefits of server-side rendering.
**3. Development and Maintenance**
_Angular and React:_
- Development often involves setting up and maintaining a complex build process with tools like Webpack, Babel, and various linters and preprocessors.
- State management and handling of large codebases can become challenging, necessitating the use of additional libraries like Redux or MobX.
- Continuous updates and breaking changes in these frameworks can introduce maintenance overhead.
_Django with HTMX and Alpine.js:_
- Django’s ORM and built-in admin interface simplify database interactions and content management.
- HTMX and Alpine.js are minimalistic and do not require complex build tools or extensive setup, reducing the maintenance burden.
- Django’s stability and long-term support releases ensure a reliable foundation for your website, minimizing disruptions from frequent breaking changes.
**4. Security**
_Angular and React:_
- Managing security in client-rendered applications requires careful handling of cross-site scripting (XSS) and other vulnerabilities.
- Additional measures are needed to protect sensitive data that might be exposed in the client-side code.
_Django with HTMX and Alpine.js:_
- Django’s built-in security features, such as protection against XSS, cross-site request forgery (CSRF), and SQL injection, provide a robust security framework.
- Server-side rendering means sensitive logic and data are kept on the server, reducing the risk of exposure to potential attackers.
- HTMX and Alpine.js, being minimalistic and handling smaller pieces of interactivity, pose a lower security risk compared to full-fledged JavaScript frameworks.
**5. Scalability and Flexibility**
_Angular and React:_
- While these frameworks can scale to complex applications, they might be overkill for standard websites, leading to unnecessary complexity.
- Handling server-side logic, authentication, and database interactions require additional backend development, often in a separate language or framework.
_Django with HTMX and Alpine.js:_
- Django provides a unified stack for both backend and frontend development, facilitating easier integration and reducing the need for context switching between different technologies.
- The modular nature of HTMX and Alpine.js allows you to add interactivity as needed, without overcomplicating the project.
- Django’s scalability features, such as built-in support for caching, async views, and robust ORM, ensure your website can grow with your needs.
**6. Deployment and Monitoring**
_Angular and React:_
- Deploying frontend frameworks involves setting up build pipelines, bundling, and ensuring compatibility across different browsers and devices.
- You need to manage static assets, deal with cache busting, and often require a content delivery network (CDN) to serve these assets efficiently.
- Monitoring client-side performance and errors can be complex, requiring additional tools and services to track user interactions, performance metrics, and JavaScript errors.
_Django with HTMX and Alpine.js:_
- Deploying a Django application is more straightforward, typically involving a single build process where both frontend and backend are integrated.
- With server-side rendering, there are fewer client-side assets to manage, simplifying the deployment process.
- Monitoring is more centralized, as server-side errors and performance can be tracked within your Django application, reducing the need for additional monitoring tools for the frontend.
**Conclusion**
For building a standard website, opting for Django with HTMX and Alpine.js offers a balanced approach that combines simplicity, performance, ease of maintenance, security, and straightforward deployment. While Angular and React are powerful tools for specific use cases, they may introduce unnecessary complexity for typical website projects. Embracing Django’s robust server-side capabilities along with the lightweight, dynamic enhancements provided by HTMX and Alpine.js can lead to a more efficient and enjoyable development experience. | documendous | |
1,883,439 | Leetcode Diary: Move Zeros | https://leetcode.com/problems/move-zeroes/ the question is super easy if you solve it by using an... | 0 | 2024-06-10T16:02:08 | https://dev.to/kevin074/leetcode-diary-move-zeros-4p8d | javascript, learning, coding, algorithms | https://leetcode.com/problems/move-zeroes/
the question is super easy if you solve it by using an extra array, using built-in methods to mutate the array via splice and then push.
However if you were to solve it in place like the question says, it isn't so easy anymore. This question is probably medium really because it requires some smart insights then.
I'll discuss my solution then another solution from the discussion section, which is actually much better, but very unintuitive (which is why I am writing this article)
My soultion was relatively simple: using two pointers, one for indexes that tracks zeros, and another for tracking non-zeros.
You write a while loop and while both indexes are less than the array length, you do:
1.) increment zeroIndex until you find the a 0 in the array
2.) increment the integerIndex while it's less than zeroIndex and the current number is a 0.
3.) both increments should stop if it is at array length
4.) swap these two indices
5.) repeat
code as below:
```
function swap (nums, i, j) {
const temp = nums[i]
nums[i] = nums[j]
nums[j] = temp
}
var moveZeroes = function(nums) {
let zeroIndex = 0
let integerIndex = 0
while (zeroIndex < nums.length && integerIndex < nums.length) {
while ( nums[zeroIndex] !== 0 &&
zeroIndex < nums.length
) {
zeroIndex++
}
while (
(
nums[integerIndex] === 0 ||
integerIndex < zeroIndex
) &&
integerIndex < nums.length
) {
integerIndex++
}
if (
zeroIndex < nums.length &&
integerIndex < nums.length
) {
swap(nums, zeroIndex, integerIndex)
}
}
};
```
it's not great, especially with the number of conditions involved, but it works :) ...
now here is the fun part...
the intuition required to get the optimal solution is:
you need to move all numbers by some number, this number is determined by **how many 0s are in front of it to start with**
therefore in the same two pointers approach a much easier way to do this is by having one pointer that tracks the current iteration and the other for tracking how many 0s have appeared in the iteration.
for each 0, you increment the zero count
for each non-zero you move it upward by the current zero count.
```
const moveZeroes = function(nums) {
let j =0;
for(let i=0; i< nums.length;i++){
if(nums[i] === 0){
j++ ;
} else {
[nums[i-j], nums[i]] = [nums[i], nums[i-j]]
}
}
};
```
this is much easier to read, but definitely harder to understand how it works.
I think during an interview if you were with this problem, the best bet to get this intuition if you go through this question carefully, and count exactly how many 0s does the number need to move forward.
I'd definitely be okay if you were to come up with some more complicated solution like the former though :) ...

In the last blog we have seen that how EDA is performed on a dataset. In this post we are going to discuss about Supervised Machine Learning and the algorithms that we can use to build our model.
So let's get started 🔥
## What is Supervised Machine Learning?
> Supervised machine learning is a type of machine learning where the algorithm learns from a labeled dataset.
Here the word **labeled** tells us that the dataset contains input as well as corresponding output values.
To understand it better let's take a dataset of **Housing Price**-:
We can see that here we have `area`, `bedrooms`, `balcony`, `age` and `price` as our columns. In this dataset the first four columns are determinant of price of a house. So we can say that **price is dependent variable and rest are our independent variable**. This is a labeled dataset.
We train our machine on the dataset so that it can make predictions for new, similar data.
**Note** that the above dataset contains numerical values only as output but we can have categorical data too. So we need to handle this very carefully to get accurate model.
## Supervised Machine Learning Problems
Based on the type of output column in our dataset, we have two types of supervised ML problem-:
- Regression Problem
- Classification Problem
**Regression Problem**
Regression is generally used for datasets where the output is continuous. The above example is a type of regression problem. The algorithms used include **Linear Regression** ,**Locally Weighted Regression**,**Lasso Regression** ,**Ridge Regression** ,**Decision Trees**, **Neural Networks**, **Random Forest** etc.
**Classification Problem**
Classification is generally used for datasets where the output is discreet. For example based on some data a candidate can either lose the election or win the election. The algorithms used include **Logistic Regression**, **Support Vector Machine**, **Decision Trees**, **Random Forest**, **Naive Bayes**, **Neural Networks** etc.
So now we are aware of the type of problems that we can encounter in Supervised Learning. In the next blog we are going to study about our very first algorithm i.e. Linear Regression.
Hope you have understood and liked this blog. Don't forget to like it and follow me.
Thankyou ❤️

So, while... | 0 | 2024-06-10T15:52:48 | https://dev.to/bkaush/single-server-setup-basics-of-system-design-b59 | systemdesign, webdev, beginners, learning |
Designing a system can look very daunting at first.
But it all starts with a small step.
So, while designing a system, we start off with a very simple approach where the system has only one server. Hence, called Single Server Setup.
A single server setup involves running your entire application stack (web server, database, application logic, etc.) on a single physical or virtual machine. It's straightforward, cost-effective, and perfect for startups or small projects where simplicity and budget are key.
## Understanding the diagram
1. Let's say you are a user, who wants to extract some examples of pet animals from `www.example.com`.
2. When you access this website through domain name (`www.example.com`), the web hosting company who is providing Domain Name System (DNS) service to this website will give you an IP address (e.g., 69.89.31.226).
3. As the IP address is provided, an HTTP (HyperText Transfer Protocol) request is sent to the web server.
4. The web server will process the request and send the desired output in the form of HTML page or JSON response to your browser.
That response is rendered by your web browser and you will be able to see the examples of pet animals.
Like you, many users must be accessing this website. So there are two main sources of traffic that can come to the server:
- **Web application:** This is accessed through a desktop device. Web application combines server-side logic (handling business processes and database communication) with client-side rendering (displaying content in browsers using HTML, CSS, and JavaScript). Together, they create interactive experiences accessible via web browsers.
- **Mobile application:** This is accessed through a mobile device. Mobile apps communicate with the web server through HTTP protocol. As JSON is a very lightweight API response format, it is used to send data from the server.
To conclude, there are many components that we are going to discuss in the system design that will extend this architecture.

Today was another solid day, I worked on my DSA Visualizer project and I think I'm almost at wrapping it up in maximum day or two. I made quite a few progress in scaling the visuals of all the structures and made it more interactive so the user is able to understand what are the intentions behind each action.
**What's next?**
I just need to add a few final touches to the app and test it on multiple test cases to see everything is smooth and then I will be ready to push it on my git repository.
**Improvements required**
I believe the project is up where I wanted it to be, for sure there must be some improvements that can be done which I will keep an out for but I think enough time is spent on this one so It's now time for me to wrap it up and move to the next interesting thing.
Wish me luck! | zain725342 |
1,883,431 | Epoch - Ethereum 2.0 | Greetings!! This is the first article that I plan to publish about random things Ethereum 2.0. In... | 0 | 2024-06-10T15:44:28 | https://dev.to/st1p3kolovrat/epoch-ethereum-20-k9f | ethereum, proofofstake, web3, blockchain | Greetings!! This is the first article that I plan to publish about random things Ethereum 2.0. In this article boss of the hour is Epoch. You will find out what is epoch in Ethereum 2.0 proof of stake, and what role does it play.
**Ethereum Epoch is a time frame during a set of validators activities are happening.**
**Activities:**
- Validators propose blocks
- Validators attest blocks proposed by others
Each epoch is divided into smaller time units, called **slots**. One epoch has 32 slots. Each slot lasts 12 seconds. Meaning each epoch lasts approximately 6.4 minutes.
One epoch therefore will have 32 blocks, and each slot will have one block.
In each slot there is one validator that is assigned to propose a new block, and a committee of validators that attest validity of that block.
---
Imagine a hotel named "The Grand Ethereum hotel". Each night, the hotel's kitchen team of chefs works together in a organised way to prepare a set of dishes for buffet dinner for hotel guests. Kitchen operates on a precise schedule to ensure fairness, efficiency, and culinary excellence.
Let us imagine one epoch is one night, or one dinner service. Therefore each epoch represents one dinner service over entire year.
For each slot, a team of chefs is involved. Among them, one chef is randomly chosen to be the Lead Chef for that slot. Selection process is fair, unpredictable and random, ensuring every chef has the opportunity to lead.
The chosen Lead Chef for that slot is responsible for making key decisions, coordinating the team's actions, and creating a dish (proposing a block).
Supporting Chefs' Role: The other chefs act as committee (attesting validators). They assist the Lead Chef by checking and supporting their decisions and actions, making sure everything is cooked perfectly. They attest the dish before it is given to hotel guests.
---
To summarise once again, In Ethereum 2.0, epoch consists of maximum 32 blocks. This means every epoch is composed of 32 slots, with each slot potentially holding one block. Slots occur every 12 seconds, making each epoch approximately 6.4 minutes long. Validators work within these epochs to propose and attest to blocks, ensuring the security and consensus of the network.

1,883,427 | NIST. framework or standard | Welcome to the world of NIST! Your question touches on some important distinctions between frameworks... | 0 | 2024-06-10T15:38:55 | https://dev.to/mikhail_dorokhovich_bd8d4/nist-framework-or-standard-23kj | Welcome to the world of NIST! Your question touches on some important distinctions between frameworks and standards, as well as the applicability and certifiability of NIST guidance. Let’s break this down:
# NIST as a Framework vs. Standard
## NIST Cybersecurity Framework (CSF):
- Framework: The NIST Cybersecurity Framework (CSF) is indeed a framework. It provides a set of guidelines and best practices to help organizations manage cybersecurity risk. The CSF is not a prescriptive standard; it’s more of a voluntary guide that organizations can adapt to their needs.
- Certification and Auditing: The NIST CSF itself is not something that organizations can get certified in. It’s intended to be flexible and adaptable, which makes it great for improving security posture but less suited for formal certification.
## NIST Special Publications (e.g., NIST SP 800-37):
- Standard: Some NIST publications can be considered more like standards. For example, NIST SP 800-37 Rev. 2, which focuses on the Risk Management Framework (RMF), provides a structured process for managing security and privacy risks. While it’s more detailed than the CSF, it is still a guideline and not a certifiable standard.
- Certification and Auditing: Organizations can align their processes with these publications, but like the CSF, there isn’t a formal certification process directly tied to NIST standards. However, following these standards closely can help in achieving other certifications (e.g., ISO/IEC 27001).
## Certifiable Standards
While NIST itself does not offer certifications, adhering to its guidelines can be part of achieving certification in other frameworks or standards. For an international school, particularly one owned by a British company, here are some alternatives and complementary standards that are certifiable:
#### ISO/IEC 27001:
This is an internationally recognized standard for information security management. While the holding company doesn’t currently work with ISO, this is the most common standard for which organizations seek certification. Implementing NIST guidelines can help prepare for ISO 27001 certification.
#### SOC 2:
Service Organization Control (SOC) 2 reports are based on the Trust Services Criteria and are relevant for service organizations. While not a NIST standard, SOC 2 audits can include controls that map to NIST guidelines.
#### GDPR Compliance:
Given that the school is owned by a British company, GDPR compliance is crucial. While GDPR is not a certification, demonstrating compliance can be supported by implementing robust security measures inspired by NIST standards.
##Implementing NIST Standards
For practical implementation, it would be beneficial to:
#### Conduct a Gap Analysis:
Compare your current practices against the NIST CSF and other relevant NIST guidelines to identify gaps.
#### Document Policies and Procedures:
Ensure all policies and procedures are well-documented and in line with the chosen NIST guidelines.
#### Engage with Stakeholders:
Work with the holding company to understand their risk management practices and align your school’s processes accordingly.
#### Prepare for Audits:
While you can’t get certified directly in NIST, prepare for audits by external parties that may verify your adherence to ISO 27001 or other standards using NIST guidelines as a foundation.
## Conclusion
NIST provides valuable frameworks and standards for enhancing cybersecurity but does not offer certification. Your school can benefit greatly from implementing NIST guidelines, and these efforts can be part of a broader strategy to achieve certifiable standards like ISO/IEC 27001 or SOC 2. Working closely with your holding company and aligning with recognized standards will be key to ensuring robust security and compliance.
For more detailed information, you can refer to the NIST website and specific publications:

As part of my research, I needed to evaluate the performance of Firecracker in serverless environments compared to traditional Linux containers (LXC). [OpenFaaS](https://www.openfaas.com), with its modular design, offered an excellent framework for this comparison. OpenFaas offered two running modes, which were OpenFaas using Kubernetes and [faasd](https://github.com/openfaas/faasd). Firecracker-containerd isn’t directly supported by Kubernetes due to the lack of a stable CRI plugin unless you consider the now unsupported [Firekube](https://github.com/weaveworks/wks-quickstart-firekube). Extending faasd to support Firecracker was simpler and served as sufficient proof of concept from my research. Otherwise, from a general point of view, the primary advantage of Firecracker over LXC in serverless computing is isolation, which isn’t crucial if you’re running faasd since serverless loads on faasd are typically trusted. So, there is no big need to do this other than plain curiosity.
With that in mind, let’s dive into the details. This guide isn’t a polished product; there are still rough edges, which I’ll cover in the conclusion section later.

To set up Firecracker, I followed the guide at [Firecracker-containerd's Getting Started](https://github.com/firecracker-microvm/firecracker-containerd/blob/main/docs/getting-started.md). The key steps involve building the necessary components by running the make command.
Before running make, I made a few adjustments to the Makefile to use `golang:1.21-bullseye` as the builder image. Then, I ran the following commands:
- `make all` to get `firecracker-ctr`, `firecracker-containerd`, and `containerd-shim-v2-firecracker`.
- `make firecracker` to get the Firecracker binary
- `make image` to get the rootfs
The goal is to have binaries for `Firecracker`, `firecracker-ctr`, `firecracker-containerd`, and `containerd-shim-v2-firecracker`, along with the Firecracker CNI plugin [`tc-redirect-tap`](https://github.com/firecracker-microvm/firecracker-go-sdk/tree/main/cni). The guide well explains each setup.
I use the `tc-redirect-tap` CNI plugin to connect containers running on Firecracker to the CNI network. A five-year-old (quite outdated) guide on Firecracker-containerd CNI networking options is found [here](https://github.com/firecracker-microvm/firecracker-containerd/blob/main/docs/networking.md). For simplicity's sake, I connect to the instances without using a network bridge and let Firecracker-containerd set up the networks. I attempted to adjust the configuration to use a network bridge, but using the `bridge` CNI plugin with the `tc-redirect-tap` plugin shows some weird behaviour, ultimately making the instance unreachable. So we set up container networking through the firecracker containerd configuration as mentioned in the [Networking Support section of the getting started guide](https://github.com/firecracker-microvm/firecracker-containerd/blob/main/docs/getting-started.md#networking-support). so ensure that your firecracker-containerd configuration files `/etc/containerd/firecracker-runtime.json` and `config.toml` are configured as per as the getting started guide.
I recommend testing out your firecracker-containerd setup and playing around with it to get comfortable with it.
## Extending faasd to firecracker-containerd
I had to set faasd to use the firecracker-containerd socket instead of the default containerd socket. While we can pass the socket and runtime using environment variables, as previously mentioned, the objective is **only** running on firecracker containerd, so we can hard set the default runtime and socket. Changing the runtime and socket at runtime using environment variables would mean adding code to handle both cases and validating the configurations of all components, which is additionaly code which we are avoiding for now. You can override the default runtime in the `ReadFromEnv` function at the `pkg/provider/config/read.go`. Changes need to be made to the `read_test.go` test file accordingly.
```go
func ReadFromEnv(hasEnv types.HasEnv) (*types.FaaSConfig, *ProviderConfig, error) {
//
// ... rest of the code is untouched
//
providerConfig := &ProviderConfig{
Sock: types.ParseString(hasEnv.Getenv("sock"), "/run/firecracker-containerd/containerd.sock"),
}
return config, providerConfig, nil
}
```
Setting default runtime for containerd at `cmd/provider.go`. runtime to `aws.firecracker`.
```go
func runProviderE(cmd *cobra.Command, _ []string) error {
//
// ... rest of the code is untouched
//
client, err := containerd.New(
providerConfig.Sock,
containerd.WithDefaultRuntime("aws.firecracker"),
)
//
// ...
//
}
```
### Changes to instance management
Swapping containerd for firecracker-containerd isn't straightforward and requires changes to the container creation code for faasd in `pkg/provider/handlers/deploy.go`. This part was a little tricky, and I must admit, I feel I might be missing a trick, but I did get it to work as intended with minimal changes, so I am going ahead and committing to it.
We would need to add `firecracker-containerd` as a dependency to the project
```bash
$ go get github.com/firecracker-microvm/firecracker-containerd/
```
and import the `firecrackeroci` submodule
```go
import (
// ... other imports
"github.com/firecracker-microvm/firecracker-containerd/runtime/firecrackeroci"
)
```
Now, we adjust the container options for firecracker-containerd by adding the `firecrackeroci.WithVMID` and `firecrackeroci.WithVMNetwork` options to be able to identify the VM and make firecracker containerd setup the networking as per the previous discussion on networking. We also commented out the mounts option as adding mounted volumes on firecracker-containerd was causing permission issues, and firecracker-containerd could not find the mounts (An issue that is persistent when running with Microk8s Kata as well).
```go
func deploy(ctx context.Context, req types.FunctionDeployment, client *containerd.Client, cni gocni.CNI, secretMountPath string, alwaysPull bool) error {
//
// ... rest of the code is untouched
//
copts := []containerd.NewContainerOpts{
containerd.WithImage(image),
containerd.WithSnapshotter(snapshotter),
containerd.WithNewSnapshot(name+"-snapshot", image),
containerd.WithNewSpec(
oci.WithImageConfig(image),
oci.WithCapabilities([]string{"CAP_NET_RAW"}),
// oci.WithMounts(mounts),
oci.WithEnv(envs),
firecrackeroci.WithVMID(name),
firecrackeroci.WithVMNetwork,
withMemory(memory)),
containerd.WithContainerLabels(labels),
}
container, err := client.NewContainer(
ctx,
name,
copts...,
)
//
// ...
//
}
```
Attaching the container IO to the faasd binary (which is faasd default behaviour) does not work with firecracker containerd, so we attach it to a temporary log file created for the container for now. Additionally, as firecracker containerd creates the CNI network for the function, we dont need to create it again here.
```go
func createTask(ctx context.Context, container containerd.Container, _ gocni.CNI) error {
name := container.ID()
task, taskErr := container.NewTask(ctx, cio.LogFile(fmt.Sprintf("/tmp/%s.log", name)))
if taskErr != nil {
return fmt.Errorf("unable to start task: %s, error: %w", name, taskErr)
}
log.Printf("Container ID: %s\tTask ID %s:\tTask PID: %d\t\n", name, task.ID(), task.Pid())
_, waitErr := task.Wait(ctx)
if waitErr != nil {
return errors.Wrapf(waitErr, "Unable to wait for task to start: %s", name)
}
if startErr := task.Start(ctx); startErr != nil {
return errors.Wrapf(startErr, "Unable to start task: %s", name)
}
ip, err := cninetwork.GetIPAddress(name)
if err != nil {
return err
}
log.Printf("%s has IP: %s.\n", name, ip)
return nil
}
```
You will notice that the `cninetwork.GetIPAddress` call has changed; we will get to this in the next section.
As you would have set which following the firecracker-containerd getting started guide, We would use the `devmapper` snapshotter. We will set the default snapshotter to devmapper, which would require changing the `snapshotter:= ""` lines to `snapshotter:= "devmapper"` in the `deploy` and `prepull` functions.
```go
func Remove(ctx context.Context, client *containerd.Client, name string) error {
//
// ...
//
} else {
snapshotter := "devmapper"
if val, ok := os.LookupEnv("snapshotter"); ok {
snapshotter = val
}
service := client.SnapshotService(snapshotter)
key := name + "-snapshot"
if _, err := client.SnapshotService("").Stat(ctx, key); err == nil {
service.Remove(ctx, key)
}
}
return nil
}
```
### Changes to networking
As the networks set up by firecracker containerd are `ptp` and setup by firecracker containerd and not by us, there are some major changes in the `cni_network` submodule. Firstly, we need to set up the CNI constants in line with the configuration passed to firecracker containerd.
```go
const (
// CNIBinDir describes the directory where the CNI binaries are stored
CNIBinDir = "/opt/cni/bin"
// CNIConfDir describes the directory where the CNI plugin's configuration is stored
CNIConfDir = "/etc/cni/conf.d"
// NetNSPathFmt gives the path to the a process network namespace, given the pid
NetNSPathFmt = "/proc/%d/ns/net"
// CNIDataDir is the directory CNI stores allocated IP for containers
CNIDataDir = "/var/run/cni"
// defaultCNIConfFilename is the vanity filename of default CNI configuration file
defaultCNIConfFilename = "fcnet.conflist"
// This value appears in iptables comments created by CNI.
defaultNetworkName = "fcnet"
// defaultSubnet is the default subnet used in the defaultCNIConf -- this value is set to not collide with common container networking subnets:
defaultSubnet = "10.64.0.0/16"
// defaultIfPrefix is the interface name to be created in the container
defaultIfPrefix = "veth"
)
// defaultCNIConf is a CNI configuration that enables network access to containers
var defaultCNIConf = fmt.Sprintf(`
{
"cniVersion": "0.4.0",
"name": "%s",
"plugins": [
{
"type": "ptp",
"ipMasq": true,
"ipam": {
"type": "host-local",
"subnet": "%s",
"dataDir": "%s",
"routes": [
{ "dst": "0.0.0.0/0" }
]
}
},
{
"type": "firewall"
},
{
"type": "tc-redirect-tap"
}
]
}
`, defaultNetworkName, defaultSubnet, CNIDataDir)
```
faasd retrieves the IP addresses for the containers by using the service name and the container task PID. However, I observed the task PID returned by the firecracker-containerd is not in line with the task PID of the firecracker process, which means the current code to retrieve the IP address would fail. So, I removed the PID parameter and used the service name to retrieve the IP address.
```go
func isCNIResultForContainer(fileName, container string) (bool, error) {
found := false
f, err := os.Open(fileName)
if err != nil {
return false, fmt.Errorf("failed to open CNI IP file for %s: %v", fileName, err)
}
defer f.Close()
reader := bufio.NewReader(f)
processLine, _ := reader.ReadString('\n')
if strings.Contains(processLine, container) {
ethNameLine, _ := reader.ReadString('\n')
if strings.Contains(ethNameLine, defaultIfPrefix) {
found = true
}
}
return found, nil
}
```
Thus we no longer need the PID to retrieve the IP address
```go
func GetIPAddress(container string) (string, error) {
CNIDir := path.Join(CNIDataDir, defaultNetworkName)
files, err := os.ReadDir(CNIDir)
if err != nil {
return "", fmt.Errorf("failed to read CNI dir for container %s: %v", container, err)
}
for _, file := range files {
// each fileName is an IP address
fileName := file.Name()
resultsFile := filepath.Join(CNIDir, fileName)
found, err := isCNIResultForPID(resultsFile, container)
if err != nil {
return "", err
}
if found {
return fileName, nil
}
}
return "", fmt.Errorf("unable to get IP address for container: %s", container)
}
```
Changes must be made to the `cni_network_test.go` test file accordingly.
The `GetIPAdress` function is also called the `pkg/supervisor.go`, which runs the Faas gateway and other processes required by OpenFaas. Therefore, we would need to modify the function call in that.
### Changes to conf files
To avoid this fork from clashing with an existing OpenFaas faasd installation, I renamed the binary and systemd services as faasd-fc; in the relevant file paths, in the `Makefile`, the systemd service files in `hack/faasd-fc.service` and `hack/faasd-fc-provider.service` and the `cmd/install.go` file.
You can build the faasd-fc binary using the command.
```bash
make dist-local
```
## Running It
You can start faasd-fc by running
```bash
sudo bin/faasd-fc install
```
Follow the instruction in the command output to setup faas-cli.
```bash
$ faas-cli ls
Function Invocations Replicas
```
I created a simple hello-world application in go to test the deployment. Lets deploy the function using faas-cli.
```bash
$ faas-cli deploy --image=alanjohn/hello-go:latest --name=hello-go --update=false
Function hello-go already exists, attempting rolling-update.
Deployed. 200 OK.
URL: http://127.0.0.1:8080/function/hello-go
```
You can use `firecracker-ctr` in the `openfaas-fn` namespace to check if the container and task for this container are running with the correct runtime and configuration. We can use `curl` to interact with the application.
```bash
$ curl http://127.0.0.1:8080/function/hello-go
hello, world!
$ faas-cli ls
Function Invocations Replicas
hello-go 1 1
```
It is working as expected
Now lets delete this function
```bash
$ faas-cli rm hello-go
Deleting: hello-go.
Removing old function.
$ faas-cli ls
Function Invocations Replicas
```
We can use `firecracker-ctr` to confirm that all resources in `openfaas-fn` namespace have been cleaned up.
## Conclusion
You can find the full code [here](https://github.com/alanpjohn/faasd-extended/tree/firecracker-support). Ideally, to get the most out of firecracker-containerd, you would want to have the firecracker instances running beforehand to remove the boot time of the firecracker VM from the time taken to start an instance as done by AWS lambda who have running firecracker microVM slots. But that would require some major refactoring to faasd and would be an overkill to faasd's intended use case. The lack of a network bridge and volume support is a more imminent issue that would completely bridge the gap between faasd and this firecracker-container extension that uses firecracker-containerd. Open to some inputs on how I could go around those. | alanpjohn |

## Inteligência Artificial
A inteligência artificial (IA) tem revolucionado diversos setores, e o campo da programação não é exceção.
O uso de IA na programação está transformando a maneira como os softwares são desenvolvidos, testados e mantidos, oferecendo novas ferramentas e métodos que podem aumentar significativamente a eficiência e a qualidade dos produtos finais.
### Aumento da Produtividade
A IA pode automatizar tarefas repetitivas e demoradas, como a revisão de código e testes de software, liberando os desenvolvedores para se concentrarem em tarefas mais complexas e criativas.
Ferramentas de IA, como os completadores de código baseados em aprendizado de máquina, podem ajudar a escrever código mais rapidamente e com menos erros.
### Melhoria na Qualidade do Código
Algoritmos de IA podem analisar grandes quantidades de código para detectar padrões e inconsistências que podem não ser evidentes para humanos, o que pode levar à identificação precoce de bugs e vulnerabilidades, reduzindo o custo e o tempo necessários para a manutenção de software.
### Personalização de Experiências de Desenvolvimento
A IA pode ser usada para adaptar ambientes de desenvolvimento às preferências individuais de cada programador, otimizando workflows e interfaces de acordo com o estilo de codificação e as tarefas mais frequentes de cada desenvolvedor.
### Dependência de Ferramentas Automatizadas
A crescente dependência de ferramentas de IA pode diminuir a compreensão dos programadores sobre o próprio código que escrevem, potencialmente levando a uma geração de desenvolvedores que podem não entender completamente o funcionamento interno do software que ajudam a criar.
### Questões de Emprego
Enquanto a automação por IA promete aumentar a eficiência, também traz preocupações sobre a substituição de empregos humanos.
À medida que as ferramentas de IA se tornam mais capazes, o papel do desenvolvedor humano pode mudar, o que levanta questões sobre a requalificação e a segurança no emprego na indústria de tecnologia.
### Ética na IA para Programação
É fundamental que os desenvolvedores compreendam e sejam capazes de explicar como as decisões foram tomadas por algoritmos de IA em seus projetos. Isso envolve garantir que a IA seja usada de maneira responsável e que seus processos sejam transparentes e justos.
### Vieses em Algoritmos
A IA é tão imparcial quanto os dados em que é treinada. Existe um risco significativo de que, sem uma supervisão adequada, os algoritmos de IA possam perpetuar ou até amplificar vieses existentes nos dados, levando a resultados injustos ou prejudiciais.

1,883,367 | Angular Forms new unified control state change events | The release of Angular v18 brought a bunch of exciting new features and improvements to the... | 0 | 2024-06-10T15:18:49 | https://medium.com/@davidepassafaro/angular-forms-new-unified-control-state-change-events-9e8e361c4777 | angular, frontend, webdev, javascript | The release of **Angular v18** brought a bunch of exciting new features and improvements to the framework.
One of these features is particularly promising, as it introduces a new capability within the **Angular Forms** library, by enhancing the **`AbstractControl`** class with unified control state change events.
As usual in my articles, before delving into the main topic, let's first review some fundamentals. This will help you better grasp the upcoming contents.
---
## Angular Reactive Forms: the fundamentals
**Angular Reactive Forms** offer a model-driven approach to handling form inputs, providing synchronous access to the data model, powerful tools for inputs validation and change tracking through **`Observables`**.
The **Reactive Forms** data model is composed using the following classes:
- **`FormControl`**: represents a single form input, its value is a primitive;
- **`FormGroup`**: represents a group of **`FormControl`**, its value is an object;
- **`FormArray`**: represents a list of **`FormControl`**, its value is an array.
A common example of form can be represented by a **`FormGroup`** like this:
```ts
import { FormGroup, FormControl, FormArray } from '@angular/forms';
const articleForm = new FormGroup({
title: new FormControl(''),
content: new FormControl(''),
tags: new FormArray([])
});
```
> **Note:** there is also the **`FormRecord`** class, an extension of the **`FormGroup`** class, which allows you to dynamically create a group of **`FormControl`** instances.
All these classes, hereafter referred to just as **controls**, are derived from the **`AbstractControl`** class, and thus share common properties and methods.
### Template binding
**Angular Reactive Forms** model-driven approach is powered by various directives provided by the library itself, which facilitate the integration of form controls with HTML elements.
Let's take the following **`FormGroup`** as an example:
```ts
this.articleForm = new FormGroup({
author: new FormGroup({
name: new FormControl(''),
}),
tags: new FormArray([ new FormControl('Angular') ]),
});
```
You can easily bind it to the template using the provided directives:
```html
<form [formGroup]="articleForm">
<div formGroupName="author">
<input formControlName="name" />
</div>
<div formArrayName="tags">
<div *ngFor="let tag of tags.controls; index as i">
<input [formControlName]="i" />
</div>
</div>
</form>
```
What is important to remember, without delving into an exhaustive but out-of-scope explanation, is that the **`FormGroupDirective`** allows us to easily create a button to **reset** the form and a button to **submit** its value:
```html
<form [formGroup]="articleForm">
<!-- form template -->
<button type="reset">Clear</button>
<button type="submit">Save</button>
</form>
```
The **`FormGroupDirective`** intercepts the click events emitted by these buttons to trigger the control's **`reset()`** function, which resets the control to its initial value, and the directive's **`ngSubmit`** output event.
### Listening for value changes
In order to listen for value changes to perform custom operations, you can subscribe to the **`valueChanges`** observable of the control you want to track:
```ts
myControl.valueChanges.subscribe(value => {
console.log('New value:', value)
});
```
### Disabled controls
Each control can be set to **disabled**, preventing users from editing its value. This mimics the behavior of the HTML **`disabled`** attribute.
To accomplish this, you can either create a control as **disabled**, or use the **`disable()`** and **`enable()`** and functions to toggle this status:
```ts
import { FormControl } from '@angular/forms';
const myControl = new FormControl({ value: '', disabled: true });
console.log(myControl.disabled, myControl.enabled) // true, false
myControl.enable();
console.log(myControl.disabled, myControl.enabled) // false, true
myControl.disable();
console.log(myControl.disabled, myControl.enabled) // true, false
```
As you can notice in the example above, the **`AbstractControl`** class provides two dedicated properties to describe this status: **`disabled`** and **`enabled`**.
### Validators
To enforce specific rules and ensure that your controls meet certain criteria, you can also specify some validation rules, or **validators**.
Validators can be **synchronous**, such as **`required`** or **`minLength`**, or **asynchronous**, to handle validation that depends on external resources:
```ts
import { FormControl, Validators } from '@angular/forms';
import { MyCustomAsyncValidators } from './my-custom-async-validators.ts';
const myFormControl = new FormControl('', {
validators: [ Validators.required, Validators.minLength(3) ],
asyncValidators: [ MyCustomAsyncValidators.validate ]
});
```
Based on these rules, the **`AbstractControl`** class provides also some properties that describe the status of the validity:
- **`valid`**: a boolean indicating whether the control value passed all of its validation rules tests;
- **`invalid`**: a boolean indicating whether the control value passed all of its validation rules tests; It is the opposite of the **`valid`** property;
- **`pending`**: a boolean indicating whether the control value is in the process of conducting a validation check.
## FormControlStatus
Both the **disabled** status and the **validation** status are interconnected.
In fact, they are derived by the **`status`** property, which is typed as follows:
```ts
type FormControlStatus = 'VALID' | 'INVALID' | 'PENDING' | 'DISABLED';
```
>**Note:** **`valid`**, **`invalid`**, **`pending`**, **`enabled`** and **`disabled`** properties are indeed just getters derived from the **`status`** property 🤓
### Pristine and Touched
The **`AbstractControl`** class provides also several properties that describe how the user has interacted with the form:
- **`pristine`**: a boolean indicating whether the control is pristine, meaning it has **not yet been modified**;
- **`dirty`**: boolean indicating whether the control **has been modified**;
- **`untouched`**: a boolean indicating whether the control has **not yet been touched**, meaning that it has not been interacted with yet;
- **`touched`**: a boolean indicating whether the control **has been touched**.
---
Now that we've revisited some of the fundamentals of **Angular Reactive Forms**, it's finally time to introduce the main topic of this article.
## New unified control state change events
Starting from Angular v18, the **`AbstractControl`** class now exposes a new **`events`** observable to track all control state change events.
Thanks to this, you can now monitor **`FormControl`**, **`FormGroup`** and **`FormArray`** classes through the following events: **`PristineEvent`**, **`PristineEvent`**, **`StatusEvent`** and **`TouchedEvent`**.
```ts
myControl.events
.pipe(filter((event) => event instanceof PristineChangeEvent))
.subscribe((event) => console.log('Pristine:', event.pristine));
myControl.events
.pipe(filter((event) => event instanceof ValueChangeEvent))
.subscribe((event) => console.log('Value:', event.value));
myControl.events
.pipe(filter((event) => event instanceof StatusChangeEvent))
.subscribe((event) => console.log('Status:', event.status));
myControl.events
.pipe(filter((event) => event instanceof TouchedChangeEvent))
.subscribe((event) => console.log('Touched:', event.touched));
```
These capabilities are very powerful, especially because, apart from the **`valueChange`**, it was previously not easy to properly track the state changes.
Additionally to this, the **`FormGroup`** class can also emit two additional events through the **`events`** observable: **`FormSubmittedEvent`** and **`FormResetEvent`**.
```ts
myControl.events
.pipe(filter((event) => event instanceof FormSubmittedEvent))
.subscribe((event) => console.log('Submit:', event));
myControl.events
.pipe(filter((event) => event instanceof FormResetEvent))
.subscribe((event) => console.log('Reset:', event));
```
Both the **`FormSubmittedEvent`** and **`FormResetEvent`** are inherited by the **`FormGroupDirective`** and are, in fact, emitted only by the directive itself.
### Additional insights
Thanks to this new addition, the following **`AbstractControl`** methods have been updated to support the **`emitEvent`** parameter:
- **`markAsPristine()`**: marks the control as **`pristine`**;
- **`markAsDirty()`**: marks the control as **`dirty`**;
- **`markAsTouched()`**: marks the control as **`touched`**;
- **`markAsUntouched()`**: marks the control as **`untouched`**;
- **`markAllAsTouched()`**: marks the control and its descendant as **`touched`**.

<p>In-house teams are becoming less vital for businesses, as modern companies are increasingly open to hiring outsourced software development teams and delegating some projects to freelancers, not just other companies. As a result, businesses are looking to nearshore their software development projects in Latin America. </p>
<p>Latin American countries have long been known for fronting a large pool of software development talent ready to bridge the skills gaps in the global IT field mainly due to the competitive prices, favorable IT policies, and exceptional services, solidifying its status as a top choice for nearshore software development.</p>
<p>As you begin your contractor hiring journey, you may ponder where to find software engineers in LATAM. To learn about the leading tech hotspots in Latin America, we have compiled industry-leading insights, providing an in-depth overview of the countries with the highest concentration of software developers in the region.</p>
<p>Happy reading!</p>
<h2>About the Method</h2>
<p>To compile this study, we used the professional LinkedIn tool—Recruiter. LinkedIn is a platform with a 630M member network, and it allowed us to find out how many Latin American developer profiles there are on the platform.</p>
<p>In addition to LinkedIn, we accessed data from Upwork to gather alternative insights into the numbers of active software developers in the LATAM region, providing a broader perspective on developer engagement and participation.</p>
<p>Our study also incorporated analysis from GitHub’s annual “State of the Octoverse” reports which provided valuable insights into global software development trends based on data from millions of repositories and contributions on their platform. This gave us valuable insights into developer communities across Latin America.</p>
<h2>Brazil—Top Pick</h2>
<figure class="wp-block-image is-resized"><img loading="lazy" src="https://lh7-us.googleusercontent.com/34EcX8P4cF3JFR_PXEpqR6mEuLS7flwg4IC9zVcfsFzZ3xybol1jpZkg3HSmsFFewcSJnO9SQ1_53VeuVHrR72xdFpGzaeTi65ifH4fqtq_Ja6sJVXHMGYcUUVIAEfmRIminL6w59yRBynKFoCNoA9o" alt="São Paulo – Brazil" width="668" height="381"><figcaption>São Paulo – Brazil</figcaption></figure>
<p>Here are the key facts about software development outsourcing to Brazil:</p>
<ul><li><strong>750k+</strong> software developers</li><li><strong>100k+</strong> IT graduates yearly</li><li><strong>$30-$60</strong> hourly developer rates</li><li><strong>US$22.41bn</strong> IT market size</li></ul>
<p>Brazil, the largest country in South America, has the largest IT market in Latin America and the 6th largest in the world. With 750,000+ active software developers, Brazil has the largest pool of well-educated and experienced developer talent in the region.</p>
<p>Brazil’s large population and growing middle class have created a significant market for technology products and services. Resultantly, Brazilian companies are increasingly looking to hire software developers who can help improve business processes and their competitiveness in the market. This has led to a growing demand for cloud computing, big data analytics, and cybersecurity professionals. It has also helped to fuel the growth of the IT services market. In 2024, revenue in the Brazilian IT services market is projected to reach US$22.41bn.</p>
<p>Brazil is also home to a large number of international IT firms. As such, Brazilian software developers will often already have experience working directly with US tech firms so they understand their context and cultural nuances. The time zone alignment with the US and Canada also allows for Brazilian software developers to have a reasonable overlap with US teams.</p>
<h2>Mexico</h2>
<figure class="wp-block-image"><img src="https://lh7-us.googleusercontent.com/JiWPMgzDoLdAA6zY0HQjDgWiqC0pAMX5hQ2arsD-vduavlJl1RU2B8pGzAQkLWPomizt4j3ZjMti9xVA5D8rflHTCXQRiptSbVWMiZ2c4eFf7EmiXw3kN7mhtQChwTxlyemH868_FGvvUgqiF22oVMY" alt="Mexico City"><figcaption>Teotihuacan – Mexico City</figcaption></figure>
<p>Here are the key facts about software development nearshoring to Mexico:</p>
<ul><li><strong>560k+</strong> software developers</li><li><strong>160k+</strong> IT graduates per year</li><li><strong>$40-$55</strong> hourly developer rates</li><li><strong>US$17.8bn</strong> IT market size</li></ul>
<p>Mexico has around 560,000 engineers involved in software development. This is largely a result of the Mexican government’s long-term policy to develop the country’s software market. One such policy is the government’s heavy investment in 38 IT clusters. These clusters have state-of-the-art equipment, stable electricity, and internet. Consequently, they have managed to cultivate a skilled IT workforce who can work remotely and bring home foreign currency. </p>
<p>For US businesses looking for remote workers closer to home, hiring Mexican developers makes a lot of sense, as the proximity of these countries to the home base eliminates major outsourcing challenges. Many US-based companies have chosen to nearshore their software development projects to Mexico due to lower software development rates, favorable business environment, high level of intellectual property protection, close people-to-people ties, and bilateral trade agreements.</p>
<p>It’s also easier to relocate Mexican developers to work in-house in the US since they can go through the NAFTA(USMCA) Visa which is simpler and has no number limitation like the HB1 Visa. Additionally, Mexico’s proximity to the United States means the cost of flying for in-person meetings is cheaper.</p>
<h2>Argentina</h2>
<figure class="wp-block-image is-resized is-style-default"><img loading="lazy" src="https://lh7-us.googleusercontent.com/iVQ33TaaWoVmO2DPZZPQqPTHBT0XqCYcclsOOm3xsfeOHK1NjnpxNzaB03jVzCma56JKPWL_3B-EgtxUWPHEAVMF2HRJzwih82EFEPDCzujW3qlPSkoU0Mo--CkWPumHJ36Bfb1H5zn2zLMZkh-_5VI" alt="Buenos Aires – Argentina " width="739" height="443"><figcaption>Buenos Aires – Argentina </figcaption></figure>
<p>Here are the key facts about software development outsourcing to Argentina:</p>
<ul><li><strong>160k+</strong> software developers</li><li><strong>15k+</strong> IT graduates yearly</li><li><strong>$45-$65</strong> hourly developer rates</li><li><strong>US$3.10bn</strong> IT market size</li></ul>
<p>Argentina, a country known for its football, delicious steak, and tango, is home to approximately 150,000 software developers. Everyone from startups to global corporations is finding the software developers they need in Argentina. Examples include IBM, Google, Oracle, Salesforce, and SAP. Software engineer statistics also show that Argentina is the fastest-growing country in Latin America for software development. According to <a href="https://github.com/github/innovationgraph/blob/main/data/developers.csv">GitHub</a> data tracking developer accounts by country—year over year—Argentina had the fastest-growing developer population. </p>
<figure class="wp-block-image"><img src="https://lh7-us.googleusercontent.com/RlFiO7MPhTUaZGHWigyLz0q-F3YN8N2Mj8eu__DbWb0eDuYLeiVSFMLG99Q5GSxyrT1EW_KClDIP18nK7VJ1GtA4nIdC1fdjBbQ2_lHVGCYdABNmMMYaKxotQ2GWT2xiCA51Pl4DnWSH7FzqaVLcEbM" alt="Argentina—has the fastest growth in GitHub developer accounts in Latin America"></figure>
<p>This growth is driven by huge demand domestically for the adoption of cloud-based services, data analytics, and artificial intelligence technologies. It’s no coincidence then that the country is home to 11 of the 34 unicorns in Latin America. This has seen Argentina emerge as an attractive destination for nearshore software development, particularly for companies in the United States.</p>
<h2>What are the risks from trying to hire software developers directly, with no assistance, in Latin America?</h2>
<p>Hiring software developers in Latin America directly can be cumbersome. The biggest deal-breaker is risk.</p>
<ul><li><strong>Visa restrictions</strong> make it too slow and cumbersome to hire these experts to work in the US. For example, in the United States, companies often need to sponsor H-1B visas for skilled foreign workers, including software developers. This process can be complex and competitive due to the limited number of visas available each year and the high demand for them.</li><li><strong>Opening a firm in Latin America to hire local developers doesn’t make sense, financially and legally</strong>. It involves substantial initial investments, ongoing operational costs, navigating complex legal and compliance requirements, and managing logistical hurdles like cultural differences and distance.</li><li><strong>Hiring remote developers from Latin America can present challenges related to support structure.</strong> Without a physical presence or local support structure, managing remote software development teams effectively, providing adequate support, and ensuring compliance with co-employment laws can be more complex.</li></ul>
<p>As experienced as you might be, chances are you probably won’t have sufficient knowledge of the local market. At Next Idea Tech, we specialize in understanding crucial aspects such as:</p>
<ul><li>Identifying companies utilizing similar technology stacks.</li><li>Recognizing reputable IT universities and specialized schools.</li><li>Determining fair and appropriate compensation.</li><li>Understanding mandatory benefits and employment requirements specific to hiring in Latin America, among other key insights.</li></ul>
<h2>So what are the legal liabilities to be aware of when hiring Latin American developers?</h2>
<p>The most common legal structures used for an nearshoring transaction in Latin America are:</p>
<ol><li><strong>The execution of a services agreement with a third party.</strong> This involves contracting with a third-party service provider to perform specific tasks or services on behalf of your company. The agreement outlines the scope of work, deliverables, timelines, payment terms, and other relevant terms and conditions.</li><li><strong>The execution of a temporary work agreement</strong>. This legal structure is used when hiring temporary or contract workers directly. It defines the terms of employment, such as duration, roles, responsibilities, compensation, benefits (if applicable), termination clauses, and legal obligations.</li><li><strong>The execution of an independent service provider contract.</strong> This applies when engaging independent contractors or freelancers to provide services without establishing an employer-employee relationship. The contract outlines the scope of services, payment terms, intellectual property rights, confidentiality provisions, and other relevant terms. </li></ol>
<p>By excluding the first option, then you will have to deal with…</p>
<h2>The cost and effort of hiring software developers in Latin America </h2>
<p>Starting and operating a business in Latin America can be complex, requiring an in-depth understanding of all the rules and regulations. </p>
<p>As an example, it takes around 60–90 days of work to start a business in Brazil, not including the time needed to open a bank account which requires extensive KYC procedures to be completed by the bank. This process can take anywhere from a few days up to a few months.</p>
<p>And if you’re thinking about hiring software developers as freelancers in Brazil, watch out: it can turn out more complicated than you imagined. There are laws that can turn this kind of work into permanent work in case the developer feels like being an actual employee of your company – then requiring its benefits and maybe even suing you.</p>
<p>And there’s more:</p>
<p><strong><em>“Argentina’s tax regime is one of the driving forces behind its complexity. The country has three tax jurisdictions that can be applicable to a corporation that operates through an Argentine PE (such as a branch or local subsidiary). Businesses operating in Argentina are subject to tax on Argentine and foreign-source income”.</em></strong> </p>
<p>Sounds like a lot of work, right? But for specialists who actually understand the process, this can be done a lot faster. </p>
<h2>Quality of hire (how can you be sure you’ve got the right person? It takes effort!)</h2>
<p>Is your HR ready to verify the tech skill level of candidates, in a foreign country? </p>
<p>We have a basic step-by-step take on tech recruiting. By doing so, we reach a deep understanding of your company culture. And also work side by side to find talents that have not only the tech skills that you need but also the cultural fit, keeping turnover under control. </p>
<p><strong>The bar is high</strong>: for 1 job position to be filled, we only deliver you the top 1-3% candidates: from 200 sourced candidates or applicants, we only introduce you to one-to-three of them. <strong>We spare you at least 25 profile interviews</strong>.</p>

1,883,379 | Master-Detail React DataGrid with Charts | In this article, I want to show you how easy it is to leverage the master-detail support in the... | 0 | 2024-06-10T15:12:28 | https://infinite-table.com/blog/2024/06/05/master-detail-datagrid-with-charts | webdev, javascript, frontend, typescript | In this article, I want to show you how easy it is to leverage the master-detail support in the [Infinite Table React DataGrid](https://infinite-table.com) in order to toggle between a table and a chart view in the row detail.
{% codesandbox gg7h4f %}
In the [RowDetail](https://infinite-table.com/docs/reference/infinite-table-props#components.RowDetail) component of Infinite Table, we render a `<DataSource />`, which in turn will render either an `<InfiniteTable />` component or a chart.
The `<DataSource />` in InfiniteTable is very powerful and does all the data processing the grid needs. All the row grouping, sorting, filtering, aggregations, pivoting are done in the `<DataSource />` - so you can use it standalone, or with InfiniteTable - it's totally up to you.
In practice, this means that you can use the `<DataSource />` to process your data and then simply pass that to a charting library like `ag-charts-react`.
```tsx
const detailGroupBy: DataSourcePropGroupBy<Developer> = [{ field: "stack" }];
const detailAggregationReducers: DataSourcePropAggregationReducers<Developer> =
{
salary: {
field: "salary",
initialValue: 0,
reducer: (acc, value) => acc + value,
done: (value, arr) => Math.round(arr.length ? value / arr.length : 0),
},
};
function RowDetail() {
const rowInfo = useMasterRowInfo<City>()!;
const [showChart, setShowChart] = React.useState(rowInfo.id % 2 == 1);
return (
<div style={{...}}>
<button onClick={() => setShowChart((showChart) => !showChart)}>
Click to see {showChart ? "grid" : "chart"}
</button>
{/**
* In this example, we leverage the DataSource aggregation and grouping feature to
* calculate the average salary by stack for the selected city.
*/}
<DataSource<Developer>
data={detailDataSource}
primaryKey="id"
groupBy={detailGroupBy}
aggregationReducers={detailAggregationReducers}
>
{/**
* Notice here we're not rendering an InfiniteTable component
* but rather we use a render function to access the aggregated data.
*/}
{(params) => {
// here we decide if we need to show the chart or the grid
if (!showChart) {
return (
<InfiniteTable
columns={detailColumns}
domProps={{
style: { paddingTop: 30 },
}}
/>
);
}
// the dataArray has all the aggregations and groupings done for us,
// so we need to retrieve the correct rows and pass it to the charting library
const groups = params.dataArray.filter((rowInfo) => rowInfo.isGroupRow);
const groupData = groups.map((group) => ({ stack: group.data?.stack, avgSalary: group.reducerData?.salary }));
return (
<AgChartsReact
options={{
autoSize: true,
title: {
text: `Avg salary by stack in ${rowInfo.data?.name}, ${rowInfo.data?.country}`,
},
data: groupData,
series: [
{
type: "bar",
xKey: "stack",
yKey: "avgSalary",
yName: "Average Salary",
},
],
}}
/>
);
}}
</DataSource>
</div>
);
}
```
The demo above is using the `ag-charts-react` package to render the charts.

1,883,375 | Understanding File Tracking Systems for Efficient Records Management | A file tracking system is a used to monitor the location and status of documents and records within... | 0 | 2024-06-10T15:09:03 | https://dev.to/file_tracker/understanding-file-tracking-systems-for-efficient-records-management-a1 | filetrackingsystem, filemanagement, rfid, barcodetracking | A file tracking system is a used to monitor the location and status of documents and records within an organization. Efficient file management is crucial in professional settings as it ensures that important documents are easily accessible and secure. This article will explore what file tracking systems are, their key features, the benefits they offer, and considerations for choosing the right system.
**What is a File Tracking System?
**
File tracking systems are designed to manage and track records within an organization. These systems help maintain an accurate log of where files are located, who has accessed them, and any changes made. Accurate file tracking is essential for organizational efficiency, as it reduces the time spent searching for documents and ensures that records are up-to-date and secure.
**Features of File Tracking Systems
**
**Computerized Records Management Software
**
Computerized records management software helps manage records efficiently by allowing organizations to import or enter data about documents, files, archives, and personnel. It establishes relationships between different records, defines user access rights, manages file locations and statuses, automates retention scheduling, tracks tasks, maintains audit trails, and generates various reports for monitoring and analysis.
**Check-Out and Check-In
**
Utilize software to query records for check-in and check-out. Documents can be labeled with barcodes or RFID labels for streamlined tracking, enabling rapid and accurate processing. The system manages file requests, notifies when files are ready for pickup, captures recipient details like fingerprints or PINs for sensitive transfers, and maintains a complete audit trail of all file movements, including transfer details and timestamps.
**Real-Time File Tracking throughout Facilities
**
Documents, files, and archives are labeled with RFID (radio wave) labels that enable real-time tracking as they travel throughout facilities. RFID antennas connect to a customer’s computer network and are ‘named’ in the database as a specific place or location. RFID antennas can be placed in work areas, along hallways, at elevators and stairwells, at department and building exits, or anywhere desired for real-time file tracking
**Passive Tracking at File Room Doorways
**
RFID antennas at file room doorways automatically track files as they exit or return, using motion sensors to determine direction. Personnel with RFID ID cards are identified when removing or returning files. Alarms, lights, and cameras provide visual, audible, and digital alerts for comprehensive monitoring, enhancing security and efficiency.
**Mobile RFID Scanners for File Tracking
**
Mobile RFID scanners are essential tools for efficiently tracking files within an organization. With a detection distance of approximately 20 feet (6 meters) or more, these scanners quickly identify files across various locations by scanning location barcodes on office door frames and other work areas. They rapidly scan all files at each location, updating the software with their current locations in real-time. Using indicators like beep speed, color-scale, and numeric index, these scanners facilitate easy file retrieval, ensuring that users can locate specific files with efficiency and accuracy.
****Prevent Unauthorized File or Archive Movements
****
RFID antennas strategically placed within facilities and at exits help prevent unauthorized movement or removal of documents and files. They detect both the items being moved and the person moving them, triggering alarms, lights, and cameras based on predefined rules. Additionally, software systems generate alerts to designated authorities via email and SMS, ensuring swift action in response to any unauthorized file movements. This RFID technology enhances security measures, effectively deterring unauthorized access to sensitive documents.
**Benefits of Implementing a File Tracking System:
**
1. Increased efficiency in file management processes
2. Reduction in errors and misplaced files
3. Enhanced security and access control
4. Cost savings through improved productivity and resource utilization
**Conclusion
**

Books are treasures that offer knowledge, entertainment, and a means to escape reality. A well-maintained reading collection can provide joy for generations. However, preserving books requires careful attention to environmental factors, handling practices, and storage solutions. This guide will provide you with essential tips to protect and preserve your reading collection.
## Understanding the Enemies of Books
## **Environmental Factors
**
Books are vulnerable to various environmental conditions. High humidity can cause mold growth, while low humidity can make pages brittle. Extreme temperatures can also be damaging. Ideally, books should be stored in an environment with a temperature between 60-70°F (16-21°C) and a relative humidity of 40-50%.
## Light Exposure
Exposure to light, especially direct sunlight, can cause the fading of book covers and pages. UV rays are particularly harmful as they can weaken paper fibers over time.
## Pests
Insects like silverfish, booklice, and termites are common threats to books. They feed on paper, glue, and other organic materials used in bookbinding.
## Handling Practices
Improper handling can cause significant damage to books. Rough handling, improper shelving, and excessive opening can lead to torn pages and broken spines.
## Proper Storage Solutions
Choosing the Right Bookshelves
Bookshelves should be sturdy and free of pests. Wooden shelves are attractive but may harbor insects if not treated properly. Metal shelves are a safer alternative. Ensure the shelves are clean and free of dust.
## Optimal Book Placement
Books should be stored upright with books of similar sizes placed together. This prevents warping and ensures even weight distribution. Avoid packing books too tightly as this can cause damage when books are removed or replaced.
## Protection from Light
Place bookshelves in a location away from direct sunlight. Use curtains or blinds to control light exposure. For added protection, consider UV-filtering covers for windows or UV-protective films for book covers.
## Climate Control
If possible, store books in a [climate-controlled environment](https://www.elpro.com/en/learn/climate-controlled-warehouse). Use dehumidifiers in humid areas and humidifiers in dry areas to maintain optimal humidity levels. Avoid storing books in basements or attics where temperature and humidity fluctuations are common.
## Handling and Cleaning Books
## Proper Handling Techniques
Always handle books with clean, dry hands to avoid transferring oils and dirt. Use both hands to support the book when reading to prevent strain on the spine. Avoid folding pages or using adhesive bookmarks, as these can damage the paper.
## Cleaning Books
Dust your books regularly with a soft, dry cloth. For deeper cleaning, use a book-specific vacuum attachment to remove dust and debris from the spine and between pages. If you encounter mold, isolate the affected book and consult a professional conservator for treatment.
## Advanced Preservation Techniques
## Acid-Free Storage Materials
Use acid-free storage materials such as boxes, tissue paper, and book covers. Acidic materials can cause paper to yellow and become brittle over time.
## Book Covers and Jackets
Protective book covers and jackets can shield books from dust, light, and physical damage. For valuable or frequently handled books, consider using polyester book jackets or archival-quality book covers.
## Repairing Damaged Books
For minor repairs, such as torn pages, use acid-free tape or a conservation glue. For significant damage, seek the help of a professional book conservator. Avoid using standard adhesive tapes and glues as they can cause further damage over time.
## Digital Preservation
## Digitizing Your Collection
Consider digitizing your reading collection to preserve the content without handling the physical books. Use a high-quality scanner to create digital copies of your books. Store digital copies on multiple devices and backup locations to prevent data loss.
## Using E-Readers
For everyday reading, use e-readers to reduce wear and tear on physical books. E-readers provide a convenient way to access your collection without risking damage to your books.
## Creating a Long-Term Preservation Plan
## Regular Inspections
Regularly inspect your reading collection for signs of damage, such as mold, pest activity, or physical wear. Early detection can prevent further deterioration.

Maintain a catalog of your books, noting their condition and any preservation actions taken. This can help track the condition of your collection over time and identify books that need special attention.
## Professional Conservation Services
For valuable or rare books, consider using professional conservation services. Conservators have the expertise and tools to handle delicate preservation tasks and can offer advice tailored to your specific collection.
## Conclusion
Protecting and preserving your reading collection requires a proactive approach to environmental control, proper handling, and regular maintenance. By following these guidelines, you can ensure that your books remain in excellent condition for years to come, allowing future generations to enjoy their timeless value. Investing time and resources into preserving your collection not only safeguards your investment but also maintains the legacy and knowledge contained within your treasured books. | blog-news | |
1,883,368 | WebRTC Vs Websocket: Which is best for your application | WebRTC and Websockets are both real time technologies, these technologies enable instantaneous... | 0 | 2024-06-10T15:05:39 | https://www.metered.ca/blog/webrtc-vs-websocket/ | webdev, javascript, webrtc, devops | WebRTC and Websockets are both real time technologies, these technologies enable instantaneous exchange of data.
Both the technologies are important for applications that require live interactions
Common use-cases for these technologies include online gaming, live chats, live streaming and other low latency applications
### **WebRTC (Web Real Time Communications)**
Webrtc allows peer to peer communication. With Webrtc you can share data and conduct video calling and live streaming. It is best for media streaming applications.
### **WebSocket**
Websocket provides full duplex communication channels. It is best for chat applications, real time notifications and updates.
Websockets also maintains persistent connections thus enabling instant data transfer between client and server.
## **Understanding WebRTC**
WebRTC is an open source tech that enables video and data transfer from peer to peer, that is different web browsers and mobile applications
WebRTC is part of the W3C consortium and thus supported by all major browsers.
Although WebRTC can be used to conduct peer2peer callling after [**Network traversal service**](https://metered.ca/stun-turn) is required such as a TURN server.
This is because NAT devices and firewall rules often block direct communication between devices on the internet.
1. P2p Communication
2. Media Streaming
3. Low Latency
## **Webrtc vs Websockets**
Here are some of the key differences between WebRTC and Websockets
## **Communication Models**
### **WebRTC's Peer to Peer Model**
WebRTC has a Peer to Peer communication model, where one device connects to another device, although this is not possible most of the time because of NAT devices, routers and firewalll rules
Video communication and data transfers are all possible with WebRTC, but these often require TURN servers to navigate the NAT
If you are looking for a TURN server service, then we recommend going for Metered TURN servers
WebRTC is generally lower latency than websockets, but has reduced server load and has end to end encryption leading to enhanced privacy
### **WebSocket's Client Server Model**
Websocket has a persistent connection between client and server, there is no scope of device to device communication in websockets.
It works between client and server. Websockets have a full duplex connection that is long lived, and this model is best for scenarios where you need a persistant connection for real time updates
These use-cases include real time notifications, real time chat
Data always passes through a central server. The reliance on server simplifies certain aspects of communication such as broadcasting to a wide user base and state management for the application
## **Performance and Latency**
### **Latency**
WebRTC generally has lower latency due to its peer to peer model and also it only requires a server to traverse NAT.
WebRTC is ideal for video calling and live streaming applications
On the other hand, Websockets exhibit higher latency because of their client server model and having a persistent connection with the server
### **Scalability Considerations**
WebRTC: When you add TURN servers in the mix WebRTC becomes infinitely scalable.
WebSocket: Websockets are also easily scalable with load balencers and clustering, although this is quite difficult as it reqires professional expertise to properly setup scalable websocket connections
## **Data Transmission**
Webrtc is optimized for video calling and stream but can also transmit any kind of data including including documents and files
Websocket is ideal choice for message based data including text and notifications
## **Security and encryption**
Webrtc uses end to end encryption using DTLS and SRTP, the communication is very secure, not even the TURN servers that are transmitting the data from one device to another cannot access the data.
Websockets you need to enable the security as it is not enabled by default, websockets uses TLS (ess://) to encrypt data between client and server, but the server has access to data unlike in webrtc where server does not have access to the data
## **Implementation Complexity**
### **Setup and configuration requirements**
Webrtc requires a TURN server for most cases to tranverse NAT and firewall rules and for connection establishment
Websocket is a simple setup with a websocket server it does not require a TURN server but requires a websocket server
### **Required Internet systems and third party systems**
Webrtc needs STUN and TURN servers and browser support for webrtc api, which is almost universally available as webrtc is implement by all the major browsers.
websockets require a websocket server TLS certificates and secure connections and handling of persistent connections, without a server websockets cannot work.
WebRTC can work without server in certain cases where the NAT rules are lax and easy to navigate.
Websockets need a websocket server, TLS certificate for secure connection and reliable server for persistent connections
## **Browser and device support**
WebRTC is supported by almost all browsers including chrome, firefox, edge safari and almost all other browsers.
Websocket is not as widely supported as webrtc, there are fallbacks available however including long polling with AJAX and server sent events if websockets are not available
| **Aspect** | **WebRTC** | **WebSocket** |
| --- | --- | --- |
| **Communication Model** | Peer-to-Peer | Client-Server |
| **Data Flow** | Directly between peers | Through a central server |
| **Latency** | Lower latenc | Slightly higher latency |
| **Best Use Cases** | Video calls, live streaming, gaming | Real-time notifications, chat apps, dashboards |
| **Scalability** | Complex (needs STUN/TURN, SFUs) | Easier with load balancers, clustering |
| **Types of Data** | Media streaming (audio, video, data) | Message-based (text, binary) |
| **Security** | DTLS/SRTP for media encryption | TLS (wss://) for data encryption |
| **Setup Complexity** | Requires STUN/TURN servers, signaling | Requires WebSocket server |
| **Infrastructure** | STUN/TURN servers, signaling server, media servers | WebSocket server, TLS certificates |
| **Browser Support** | Most modern browsers (Chrome, Firefox, Safari, Edge) | Broad support across modern browsers |
| **Fallback Options** | WebSocket for signaling, other libraries | Long-polling, Server-Sent Events (SSE) |
| **Performance** | Optimized for low latency media transfer | Suitable for real-time message transmission |
| **Implementation** | More complex due to NAT traversal, signaling | Simpler, with established libraries |
| **Network Topology** | Direct peer-to-peer, complex NAT traversal | Centralized client-server |
| **Examples** | Video conferencing, remote desktop | Chat systems, live feeds, real-time updates |

## **How Webrtc Works**
WebRTC enables real time communication between devices. WebRTC is designed to handle a wide range of data transfer applications including video calling and file transfer application.
In this section we are going to learn how the webrtc works:
### **Core Components WebRTC Architecture**
### **Media Capture and Encoding**
* Media Devices: The media devices are handled by the `getUserMedia()` api method. It captures the media from cameras, microphones, and other input devices
* Encoding: Encoding automatically compresses the media streams using codecs like VP8/VP9 for video and audio
### **Signalling**
* Purpose: Signalling exhanges the connection information like session descriptions and ICE candidates between devices that want to connect to each other
* Mechanism: WebRTC needs a signalling server to exchange messages but does not specify any perticular messagign system. You can use any messaging system that you prefer including WebSockets, SIP or XMPP
* Process: The signalling process involves exchange of SDP data and ICE candidates necessary for the connection
### **NAT Traversal**
* [**STUN Servers (Session Traversal utilities for NAT)**](https://www.metered.ca/tools/openrelay/stun-servers-and-friends/): Helps devices that are behind NAT discover their own IP addresses, which they can use to echange with each other and establish a direct connection. You can learn more about [**STUN servers**](https://www.metered.ca/tools/openrelay/stun-servers-and-friends/)
* [**TURN Servers ( Traversal Using Relays around NAT):**](https://www.metered.ca/stun-turn) TURN servers relay traffic between devices that are behind strict NAT and firewall rules where direct connection is not possible. You need TURN servers to be near your client devices that is why when considering a TURN server provider you need one that has server all over the world. One such provider is Metered.ca TURN server service provider with TURN server all over the world.
### **Peer Connection**
* **RTCPeerConnection:** This api manages the webrtc connection , handles media echange and performs ICE negotiation for the best path between peers.
* **ICE framework (Interactive connectivity establishment)** ICE servers gathers ICE candidates and network paths and establishes the connection using the best path possible. The ICE framework first tries to establish a direct connection using STUN servers but this often fails due to NAT and routers and firewall rules
### **Data Channels**
RTCDataChannels: This API allows transmission of arbitary data such as for file transfer, text chats and other media streams
## **Signalling Process, STUN / TURN servers**
### **STUN server**
Function: The STUN server replies back to any request that comes it with the request IP address and port number of the device from which the request is comming from. Thus letting the device which are behind a NAT know their own IP address and port number.
Usage: Once device knows what their IP address and port number is, the device can then exchange this information with another device across the internet with which it want to establish a direct webrtc connection. This fails may times because NAT and firewall rules block direct connection with external devices and then the ICE frameworks tries to establish the network using TURN servers between devices.
### **TURN servers**
Function: Relays encrypted data through its servers in a peer to peer connection to traverse NAT
Usage: Sure shot way to traverse NAT when all other options fail. TURN server succeeds
## **Peer to Peer Connection establishment**
### **Signalling Exchange**
* Device X. sends a SDP offer to Device Y Through a signalling server
* Device Y recieves the offer, creates and SDP answer and sends it back
* Both the devices exchange ICE candidates using the signalling server
### **ICE Candidates Gathering**
* Devices gather all the possible network paths that could be taken to reach other device. That is using STUN and if that fails using TURN servers
### **Connection Checks**
* Both the devices perform connectivity checks to test the gathered candidates to make sure which route to take that is direct connection via STUN or relay connection through TURN servers
### **Media Path Establishment**
* Once the route is establsihed then the devices connecgt with each other and start the connection and video call
## **How Websockets Works**
Websocket is a communication protocol using which you can establish a full duplex communication channel that is always on. That is until and unless it is disconnected
Websockets work over TCP connection, which is widely used. The Websocket protcol is designed to be lightweight, simple and easy to use
### **Key aspects of Websocket protocol**
The Websocket protocol is designed to facilitate real time full duplex communication, which is different from http because http connection ends when a request reaches its destination and get a reply for that request
A new connection is created for another request. In Websockets the connection is active unless it is closed by the server or the client
The full duplex connection in websocket means that the server and the client can recieve the messages simultaneously
### **Single TCP connection**
The websockets work over a single TCP connection which is open till the either the server or the client closes the connection.
### **Message framing**
Websocket data have message frameming where a single message contains both 1. a Metadata with information about type of data being sent and other misc technological data. 2. It also contains the payload the action data that a client wants to send to the server and to other clients
### **Low Latency**
The websocket connection is always open, therefore once the connection is established there is low latency when sending messages from the client to the server and from the server to the client | alakkadshaw |

however, here's the brutal truth - the conversion rate from impressions to signups was only **0.11%** at **just 22 new users.**
a 0.11% conversion is extremely **low**, indicating that my current approach and messaging needs refinement. for a product to be viable long-term, i'd want at least a 3-5% conversion rate from marketing efforts.
so what's next?
i have a crucial decision to make - **either double down on quotesai** by pivoting to create something more useful and valuable, **or start fresh** on a new project idea entirely.
i'm leaning towards iterating on quotesai based on the initial promising traction. over the next couple of weeks, i'll be:
researching and analyzing data to understand user needs better
speaking to some of you to gather qualitative feedback
ideating on new features/pivots that can drive higher conversions
> my goal is to build something that people genuinely want and will happily use daily.
this is just the beginning of my journey building in public. i'll continue sharing regular updates on my progress, what's working well, what's not, and most importantly - the lessons i'm learning along the way.
i hope that by documenting my process transparently, i can inspire others to launch their own open source projects too!
so stay tuned for more by following me on twitter @kathanmehtaa. let's grow quotesai (or whatever it evolves into) together!
if you are interested in checking out quotesai github repo → [click here](https://github.com/DarkInventor/QuotesAI)
and if u want to play around with quotesai → [click here](https://quotesai.vercel.app/)
i will see u in the next update till then lfg!
and, happy coding :)
ps- if u are interested in knowing more about how do i market my projects, what channels i use, and what i use lemme know and i will write about it by sharing my real world examples of how i do it and you can too.

1,882,172 | Spring Boot 3 application on AWS Lambda - Part 7 Measuring cold and warm starts with AWS Lambda Web Adapter | Introduction In the part 5 of the series we introduced AWS Lambda Web Adapter tool, and in... | 26,522 | 2024-06-10T15:01:37 | https://dev.to/aws-builders/spring-boot-3-application-on-aws-lambda-part-7-measuring-cold-and-warm-starts-with-aws-lambda-web-adapter-310h | aws, serverless, java, springboot | ## Introduction
In the [part 5](https://dev.to/aws-builders/spring-boot-3-application-on-aws-lambda-part-5-introduction-to-aws-lambda-web-adapter-m21) of the series we introduced AWS Lambda Web Adapter tool, and in the [part 6](https://dev.to/aws-builders/spring-boot-3-application-on-aws-lambda-part-6-develop-application-with-aws-lambda-web-adapter-h88) we explained how to develop Lambda function with AWS Lambda Web Adapter using Java 21 and Spring Boot 3.
In this article of the series, we'll measure the cold and warm start time including enabling SnapStart on the Lambda function but also applying various priming techniques like priming the DynamoDB invocation and priming the whole web request. We'll use Spring Boot 3.2 [sample application](https://github.com/Vadym79/AWSLambdaJavaWithSpringBoot/tree/master/spring-boot-3.2-with-lambda-web-adapter) for our measurements, and for all Lambda functions use JAVA_TOOL_OPTIONS: "-XX:+TieredCompilation -XX:TieredStopAtLevel=1" and give them Lambda 1024 MB memory. Current Spring Boot version 3.3. should work out of the box by switching the version in the POM file.
## Measuring cold starts and warm time with AWS Lambda Web Adapter and using Java 21 and Spring Boot 3
Enabling SnapStart on Lambda function is only a matter of configuration like :
```
SnapStart:
ApplyOn: PublishedVersions
```
applied in The Lambda Function Properties or Global Functions section of the SAM template, I'd like to dive deeper to how to use priming on top of it for our use case. I explained the ideas behind priming (in our case of DynamoDB request) in my article [AWS Lambda SnapStart - Part 5 Measuring priming, end to end latency and deployment time](https://dev.to/aws-builders/measuring-java-11-lambda-cold-starts-with-snapstart-part-5-priming-end-to-end-latency-and-deployment-time-jem)
The code for priming of DynamoDB request can be found [here](https://github.com/Vadym79/AWSLambdaJavaWithSpringBoot/blob/master/spring-boot-3.2-with-lambda-web-adapter/src/main/java/software/amazonaws/Priming.java).
This class Priming is additionally annotated with
@Configuration so it will be initialized as well before the initialization of bean, repositories and controllers is completed.
It implements import org.crac.**Resource** interface of the [CraC project](https://openjdk.org/projects/crac/).
With this invocation
```
Core.getGlobalContext().register(this);
```
Priming class registers itself as CRaC resource. We additionally prime the DynamoDB invocation by implementing **beforeCheckpoint** method from the [CRaC API](https://openjdk.org/projects/crac/).
```
@Override
public void beforeCheckpoint(org.crac.Context<? extends Resource> context) throws Exception {
productDao.getProduct("0");
}
```
which we'll be invoked during the deployment phase of the Lambda function and before Firecracker microVM snapshot is taken.
Web request invocation priming that we explored with AWS Serverless Java Container in the article [Spring Boot 3 application on AWS Lambda - Part 4 Measuring cold and warm starts with AWS Serverless Java Container](https://dev.to/aws-builders/spring-boot-3-application-on-aws-lambda-part-4-measuring-cold-and-warm-starts-with-aws-serverless-java-container-mb0) is not applicable to AWS Lambda Web Adapter as the latter doesn't offer the formal API for the request invocation as AWS Serverless Java Container does.
The results of the experiment below were based on reproducing more than 100 cold and approximately 100.000 warm starts with Lambda function with 1024 MB memory setting for the duration of 1 hour. For it I used the load test tool [hey](https://github.com/rakyll/hey), but you can use whatever tool you want, like [Serverless-artillery](https://www.npmjs.com/package/serverless-artillery) or [Postman](https://www.postman.com/).
I ran all these experiments on our **GetProductByIdWithSpringBoot32WithLambdaWebAdapter** Lambda function with 3 different scenarios with compilation option "-XX:+TieredCompilation -XX:TieredStopAtLevel=1" (client compilation without profiling). For further explanation please read my article about this topic [AWS SnapStart - Part 14 Measuring cold starts and deployment time with Java 21 using different compilation options ](https://dev.to/aws-builders/aws-snapstart-part-14-measuring-cold-and-warm-starts-with-java-21-using-different-compilation-options-el4)
1) No SnapStart enabled
in template.yaml use the following configuration:
```
Globals:
Function:
Handler: run.sh
CodeUri: target/aws-spring-boot-3.2-lambda-web-adapter-1.0.0-SNAPSHOT.jar
Runtime: java21
....
#SnapStart:
#ApplyOn: PublishedVersions
```
2) SnapStart enabled but no priming applied
in template.yaml use the following configuration:
```
Globals:
Function:
Handler: run.sh
CodeUri: target/aws-spring-boot-3.2-lambda-web-adapter-1.0.0-SNAPSHOT.jar
Runtime: java21
....
SnapStart:
ApplyOn: PublishedVersions
```
If we'd like to measure cold and warm starts, so the priming effect won't take place for the SnapStart enabled Lambda function we have to additionally remove **@Configuration** annotation from the [Priming class](https://github.com/Vadym79/AWSLambdaJavaWithSpringBoot/blob/master/spring-boot-3.2-with-lambda-web-adapter/src/main/java/software/amazonaws/Priming.java) or delete the entire Priming class.
3) SnapStart enabled with DynamoDB invocation priming
in template.yaml use the following configuration:
```
Globals:
Function:
Handler: run.sh
CodeUri: target/aws-spring-boot-3.2-lambda-web-adapter-1.0.0-SNAPSHOT.jar
Runtime: java21
....
SnapStart:
ApplyOn: PublishedVersions
```
and leave the Priming class described above as it is, so the priming effect takes place.
I will refer to those scenarios by their numbers in the tables below, for example scenario number 3) stays for "SnapStart enabled with DynamoDB invocation priming". Abbreviation **c** is for the cold start and **w** is for the warm start.
**Cold (c) and warm (w) start time in ms:**
|Scenario Number| c p50 | c p75 | c p90 |c p99 | c p99.9| c max |w p50 | w p75 | w p90 |w p99 | w p99.9 | w max |
|-----------|----------|-----------|----------|----------|----------|----------|-----------|----------|----------|----------|----------|----------|
|1|4777.94|4918.46|5068.17|5381.41|5392.18|5392.33|8.60|9.77|11.92|25.82|887.92|1061.54|
|2|1575.49|1649.61|2132.75|2264.57|2273.64|2274.45|8.26|9.38|11.09|23.46|1136.71|1161.12|
|3|674.35|709.61|974.14|1114.87|1195.66|1196.79|8.00|8.80|10.16|21.84|317.66|624.33|
## Conclusion
By enabling SnapStart on the Lambda function alone, it reduces the cold start time of the Lambda function significantly. By additionally using DynamoDB invocation priming we are be able to achieve cold starts only slightly higher than cold starts described in my article [AWS SnapStart -Measuring cold and warm starts with Java 21 using different memory settings](https://dev.to/aws-builders/aws-snapstart-part-14-measuring-cold-and-warm-starts-with-java-21-using-different-compilation-options-el4) where we measured cold and warm starts for the pure Lambda function without the usage of any frameworks including 1024MB memory setting like in our scenario.
Comparing the cold and warm start times we measured with AWS Serverless Java Container in the article [Measuring cold and warm starts with AWS Serverless Java Container](https://dev.to/aws-builders/spring-boot-3-application-on-aws-lambda-part-4-measuring-cold-and-warm-starts-with-aws-serverless-java-container-mb0) we observe that AWS Lambda Web Adaptor offers much lower cold start times for all scenarios. Even priming DynamoDB invocation with AWS Lambda Web Adapter offers lower cold start times than the web request invocation priming for the Serverless Java Container. Warm start times are very similar for both approaches being very slightly lower for Serverless Java Container.
In the next part of the series, I'll introduce Spring Cloud Function project and concepts behind it as another alternative to develop and run Spring Boot applications on AWS Lambda. | vkazulkin |

In this blog, we’ll walk through the steps to Dockerize a React application. Dockerizing your app can provide numerous benefits, such as ensuring consistency across environments, simplifying the deployment process, and improving scalability. Let's dive into the process!
**Prerequisites**
Before we start, make sure you have the following installed:
1. **Node.js** and **npm**: You can download and install them from [Node.js official website](https://nodejs.org/en).
2. **Docker**: Download and install Docker from [Docker's official website](https://www.docker.com/).
## Step 1: Create a React App
If you already have a React app, you can skip this step. Otherwise, let's create a simple React app using create-react-app:
```
npx create-react-app my-react-app
cd my-react-app
```
## Step 2: Create a Dockerfile
A Dockerfile is a script that contains a series of instructions on how to build a Docker image for your application. Create a file named Dockerfile in the root of your React project with the following content:
Dockerfile
```
# Use an official Node.js runtime as a parent image
FROM node:14-alpine
# Set the working directory in the container
WORKDIR /app
# Copy package.json and package-lock.json to the working directory
COPY package*.json ./
# Install dependencies
RUN npm install
# Copy the rest of the application code to the working directory
COPY . .
# Build the React app
RUN npm run build
# Install a simple web server to serve static files
RUN npm install -g serve
# Set the command to run the web server
CMD ["serve", "-s", "build"]
# Expose port 5000 to the outside world
EXPOSE 5000
```
This Dockerfile performs the following steps:
**FROM**: Specifies the base image. Here, we use a lightweight Node.js image based on Alpine Linux.
**WORKDIR**: Sets the working directory inside the container.
**COPY package.json ./**: Copies package.json and package-lock.json to the working directory.
**RUN npm install**: Installs the project dependencies.
**COPY . .**: Copies the entire project to the working directory.
**RUN npm run build**: Builds the React application.
**RUN npm install -g serve**: Installs serve, a simple web server for serving static files.
**CMD ["serve", "-s", "build"]**: Specifies the command to run the web server.
**EXPOSE 5000**: Exposes port 5000, which serve uses by default.
## Step 3: Build the Docker Image
Open a terminal, navigate to your project directory, and run the following command to build the Docker image:
```
docker build -t my-react-app .
```
This command builds the Docker image using the Dockerfile in the current directory (.) and tags it as my-react-app.
## Step 4: Run the Docker Container
Once the image is built, you can run a container using the following command:
```
docker run -p 5000:5000 my-react-app
```
This command maps port 5000 of the container to port 5000 on your local machine, allowing you to access the app in your browser at http://localhost:5000.
## Step 5: Verify the Setup
Open your browser and navigate to http://localhost:5000. You should see your React application running!
## Conclusion
Congratulations! You have successfully Dockerized your React application. By containerizing your app, you ensure a consistent environment across development, testing, and production, making deployments more predictable and scalable.
To summarize, here’s what we did:
1. Created a React app.
2. Wrote a Dockerfile to define the steps to containerize the app.
3. Built a Docker image from the Dockerfile.
4. Ran a Docker container from the image.
5. Verified that the app is running correctly.
With Docker, you can take advantage of containerization to streamline your development and deployment workflows. Happy coding! | hemanthreddyb |

1,883,361 | Using Snippets in Visual Studio Code | Introduction Compared to the posts I have uploaded so far, this will be super short and... | 0 | 2024-06-10T14:52:53 | https://dev.to/7jw92nvd1klaq1/using-snippets-in-visual-studio-code-1j97 | ## Introduction
Compared to the posts I have uploaded so far, this will be super short and brief, so I will briefly go through the topic of **Snippets** and how you should utilize it in Visual Studio Code, to ultimately enhance your experience as a developer! I am writing this as an assignment of the coding bootcamp that I am currently attending right now, so like I previously mentioned, it will be very concise and right to the point.
## Snippets?
Snippets are simply bits of code that you frequently utilize in your daily coding lives, that you tend to sort of copy and paste in so many parts of your projects. For example, to create an HTML document, you mostly start with the very line, which is `<!DOCTYPE html>` followed by various tags, such as `<html>`, `<head>`, `<body>`, etc. Quickly, having to repeat the patterns of typing all those manually become somewhat tedious, and you want to find the solution to simply not having to repeat those manually, every time you create a new page for your website. That's where Snippets come in. By using a functionality that simply include the code at your whim, you tend to use less time having to set up the basic structure of code, which simply allows you to save your time and let you work towards your goal from the get-go.
## How to use it?
I am currently writing this in context of using Visual Studio Code by Microsoft, since it seems to be the most convenient and advanced form of IDE currently. To enable the functionality of **Snippets** in VSC, we first have to download the extension called **Snippet Generator** by the user called **fiore**.
I will use part of what I am currently working on as an example, in an effort to showcase the usage of the extension we have downloaded. To give you context, as part of the project, I am currently creating the frontend of the bookshop project that I have been working on for some time, using TypeScript and React. In React, there is a thing called a component, which is basically a piece of reusable code that may be used throughout a project. To create a component, you tend to repeat the same process: You first have to create a function, import the same libraries, etc. Like I said, it starts feeling really tedious and annoying. I will show you in an example below, alongside **how to register and use snippets**.
Regardless of the nature of the language and the project you are working on, as long as you feel like you tend to repeat a lot of the same code over and over again, throughout your experience as a developer, it's going to come very useful.
```
import styled from "styled-components";
import { useForm } from "react-hook-form";
import InputText from "../components/common/InputText";
import useAuth from "../hooks/useAuth";
const Login = () => {
const { userLogin, error } = useAuth();
const { handleSubmit, register } = useForm<LoginFormProps>();
return (
<LoginStyle>
<form onSubmit={handleSubmit(userLogin)}>
<InputText placeholder="Email" inputType="text" {...register("email")} />
<InputText placeholder="Password" inputType="password" {...register("password")} />
<button type="submit">Login</button>
</form>
{error && <p>{error}</p>}
</LoginStyle>
);
};
const LoginStyle = styled.div`
padding: ${props => props.theme.layout.medium.padding};
background-color: ${props => props.theme.color.background};
border-radius: 0.25rem;
`;
export default Login;
```
Above is a file for containing the component called `Login`, which is rendered and displayed on the screen, when a user decides to log in to the website. Some of the notable lines in the code block includes the followings:
- **import styled from "styled-components";**
- **styled** is used in every page component. Definitely a part worth being a part of the snippet.
- **const Login**
- You may replace the word **Login**, with any name that you would like to call your component with. Regardless of whatever page component you create, you always have to name a component, so it is something that gets repeated every time.
- **const LoginStyle**
- This is also a bit of code that gets used for every page component. Just with the example above replacing the name of the component, we may replace the substring **Login** with the same name that the component is named after, so it is definitely worth making this part of the snippet for creating a page component.
- **export default Login;**
- Lastly, using the component **Login** in other files requires it being exported. This line gets used in every page component, and should be a part of the snippet. Just with the variable **LoginStyle**, this contains the name of the component, so you know what to do.
Identifying bits of lines that may be incorporated and used in other files that contain a page component, we end up with the following code block:
```
import styled from "styled-components";
const Login = () => {
return (
<LoginStyle>
</LoginStyle>
);
};
const LoginStyle = styled.div``;
export default Login;
```
Okay, so let's get to turning the code above into the snippet!
### 1. Replace the name of the component
- Before we turn those into a snippet that we would like to use over and over again, we have to prep them into being used as one. Like I said, in order to reuse the bits of code above, all we have to do is to replace the name of the component, which in this case is **Login**, with its respective name. Replace its name with `$1`
```
import styled from "styled-components";
const $1 = () => {
return (
<$1Style>
</$1Style>
);
};
const $1Style = styled.div``;
export default $1;
```
- As you can see, I have replaced the substring **Login** with the substring **$1**.
### 2. Highlight, Right-click them, and choose an option for creating a snippet
If you have installed the extension I mentioned at the beginning, once you right-click the highlighted section of the code, you should see the option called **Generate snippet** in the options.
### 3. Choose the programming language
What programming language is the code based on? If you are writing a snippet for C language, then choose C. Since I am trying to use this snippet to automate the initial process of creating a page component, I will choose the option **typescriptreact**.
### 4. Name a snippet
Name it how you like!
### 5. Choose the prefix
The prefix is basically used to generate the snippet in your code. **The naming convention seems to be that it should always start with the underscore character**, for the fact that it may be more distinct and may not be confused with other items in the autocompletion feature that VSC provides us with.
### 6. (Optional) Provide a description
Maybe you would like to explain to yourself what it is used for, for future references. This step is completely optional, so you may skip this step by simply pressing the **ENTER** on your keyboard!
### 7. Let's use this
Typing the prefix of the snippet that I just created, I get prompted with the following autocomplete. By pressing **ENTER**, I end up with the following snippet of code, with which I can start working on making a new page component right away! | 7jw92nvd1klaq1 | |

Yes, already! If you missed the first week, go back and read it [here](https://dev.to/nmiller15/learn-while-you-code-html-and-css-part-1-3064). As with week one, read through the brief lesson below, and then complete the challenge to learn as you code!
## Creating an HTML Document
All of the internet is just made up of text. In fact, all computers only read text (or well text, that breaks down to binary), but everything that you see on a website or on your phone screen is made up of characters. To create a web page, we have to put this into a specific format so that the computer knows how to read it. It's kind of like putting your essays in MLA or Chicago format in school so that your teacher could read it easier except much more strict!
### Elements
An HTML document is made up of what are called **elements**. These elements are represented by an opening tag, closing tag, and content. Below is a basic page, but with no content. Notice, will still have three elements on it, the `<html>` element, the `<head>` element and the `<body>` element. A blank page would look something like this:
```html
<!DOCTYPE html>
<html>
<head></head>
<body></body>
</html>
```
Most HTML elements will be represented with both an opening tag ( `<>` ) and a closing tag ( `</>` ). Anything between the opening and closing tag is said to be *within* that element, or a *child* of that element.
### `<html>`, `<head>` and `<body>`
In an HTML document, every element is a child of the `<html>` element, so all of your elements should be *inside* that one. The `<head>` and the `<body>` tags are also top level, structural elements that divide the `<html>` element into two sections. The `<head>` element will contain all of your metadata, information about the page, and the `<body>` element contains all of the visible elements of the page. You need these elements for the page to be HTML. Above is the simplest version of HTML *boilerplate,* or code that will always need to be there to function as expected.
### <!DOCTYPE html>
The other bit of boilerplate that we see in the above example is `<!DOCTYPE html>` . This is a document type declaration. We give different types of files to a browser to construct a webpage, and to signal to the browser that what it is about to read is HTML, we must include this declaration at the top of all of our HTML documents.
With this information you have all that you need to create a webpage that you can open in a browser on your computer!
## Challenge: Build a Web Page
### 1. Download a text editor.
Go to your web browser and find a text editor. If you want you can use the one on your computer already (TextEdit for Mac, Notepad for Windows). But, I would recommend that you download VS Code from their website for free!
### 2. Create a file called index.html and add the HTML Boilerplate to it.
Don't forget to declare your document type and to wrap your `<head>` and `<body>` tags with your `<html>` element tags.
### 3. In between the opening and closing `<body>` tags, type "Hello World!" and save the document.
You don't have to worry about any other elements for now, and it is okay that the `<head>` element does not contain anything.
### 4. Save your index.html file and double click to open your first webpage! Congratulations!
You may have to right click on the document and choose "Open with…" > Google Chrome (or whatever browser you are using.
Congratulations! You're a web developer now. You've just created a document that is readable by your browser! For an extra challenge, go ahead and check out MDN's website and see if you can locate the tag that will allow you to change the text that is displayed in your browser's tab while the page is open!
Good work! In the next part of this HTML and CSS series we will look closer at the different types of visible elements for your web page to make our web page a little more interesting! See you next time, and don't forget to:
Learn as You Code!

##Apache Kafka
============
Apache Kafka is an open-source distributed event streaming platform used for building real-time data pipelines and streaming applications.
Architecture of Kafka
---------------------
Kafka has a distributed architecture consisting of the following components:
* **Producer:** Applications that produce data and send it to Kafka topics.
* **Broker:** Kafka runs as a cluster of one or more servers called brokers, which store and manage the data.
* **Topic:** A category or feed name to which messages are published by producers.
* **Partition:** Topics are divided into partitions for scalability and parallelism.
* **Consumer:** Applications that subscribe to topics and consume the data.
* **ZooKeeper:** Coordinates and manages Kafka brokers.
The architecture allows for horizontal scaling, fault tolerance, and high throughput.

The decision to use SQL (Structured Query Language) or NoSQL (Not Only SQL) databases depends on various factors such as the nature of the data, scalability requirements, and the specific needs of your application. Here are some guidelines to consider
**Data Structure and Schema Flexibility:**
-
Use SQL databases when you have a structured data model with a fixed schema. SQL databases enforce a schema, which ensures data consistency and integrity.
-
Use NoSQL databases when you have unstructured or semi-structured data, or when your data model is expected to evolve frequently. NoSQL databases offer schema flexibility, allowing you to store and retrieve data without a predefined schema.
**Scaling:**
-
Use NoSQL databases for horizontal scalability. They are designed to scale out across multiple servers or clusters, making them suitable for handling large volumes of data and high write loads.
-
SQL databases can also scale vertically (by increasing server capacity) but may face limitations in horizontal scaling due to the rigid structure enforced by the relational model.
**Complex Queries and Transactions:**
-
Use SQL databases when your application requires complex queries involving multiple tables, joins, and aggregations. SQL databases excel at handling complex relational queries.
-
NoSQL databases may not be as suitable for complex queries involving multiple entities or relationships. They typically prioritize fast data retrieval and simple queries over complex relational operations.
**ACID Compliance:**
-
Use SQL databases when your application requires ACID (Atomicity, Consistency, Isolation, Durability) compliance for transactions. SQL databases provide strong consistency guarantees and ensure data integrity.
-
NoSQL databases often sacrifice strong consistency for performance and scalability. They may offer eventual consistency or relaxed transaction guarantees, which might be acceptable depending on your application's requirements.
**Data Volume and Speed:**
-
Use NoSQL databases when dealing with large volumes of rapidly changing data, such as in real-time analytics, IoT (Internet of Things) applications, or social media platforms.
-
SQL databases are suitable for applications with structured data and moderate to high transactional requirements, such as e-commerce platforms, financial systems, and enterprise applications.
**Development and Deployment Flexibility:**
-
NoSQL databases are often favored for agile development and rapid iteration, as they offer more flexibility in data modeling and schema evolution.
-
SQL databases may require more upfront planning and schema design but can offer better tooling, mature ecosystems, and robust transactional support for enterprise applications.
Ultimately, the choice between SQL and NoSQL databases depends on your specific use case, performance requirements, scalability needs, and development preferences. In some cases, a combination of both types of databases (polyglot persistence) might be appropriate, leveraging the strengths of each for different parts of your application.

1,883,353 | Quick Start Guide: React for the Rest of Us (With a Dash of Humor!) | Welcome to the ultimate guide to get you started with React.js. Let's dive into the React universe,... | 0 | 2024-06-10T14:45:05 | https://dev.to/ahnaf2009/quick-start-guide-react-for-the-rest-of-us-with-a-dash-of-humor-17eh | react, quickstartreactjs, javascript, componen | Welcome to the ultimate guide to get you started with React.js. Let's dive into the React universe, where you’ll learn the essential concepts you’ll use daily. It’s like learning to cook: master the basics, and you can whip up anything from a simple sandwich to a fancy gourmet dish.
## What You’ll Learn:
- How to create and nest components
- How to add markup and styles
- How to display data
- How to render conditions and lists
- How to respond to events and update the screen
- How to share data between components
---
## Creating and Nesting Components: Assemble Your Superhero Squad
React apps are made out of components. Think of a component as a piece of the UI (user interface) with its own logic and appearance. It can be as small as a button or as large as an entire page.
### Step 1: Creating a Simple Component
Imagine you’re introducing a new superhero to your squad. Here’s our first superhero: a button!
```jsx
function MyButton() {
return <button>I'm a button</button>;
}
```
Our hero is simple but effective. It’s a JavaScript function that returns a bit of HTML (called JSX in React). Now, let’s nest this superhero into another component, like adding Batman to the Justice League.
### Step 2: Nesting Components
Just like Batman works better with his team, our button can be part of a bigger component. Let’s create an app that welcomes users with a button.
```jsx
export default function MyApp() {
return (
<div>
<h1>Welcome to my app</h1>
<MyButton />
</div>
);
}
```
Notice that `<MyButton />` starts with a capital letter. That’s the rule: React component names always start with a capital letter, while HTML tags are lowercase. Think of it as giving your heroes proper names.
---
## Writing Markup with JSX: Speak the Superhero Language
The markup syntax you’ve seen above is called JSX. It’s optional but super convenient. JSX is stricter than HTML. You have to close tags like `<br />` and wrap multiple tags in a shared parent, like `<div>...</div>` or an empty `<>...</>` wrapper.
```jsx
function AboutPage() {
return (
<>
<h1>About</h1>
<p>
Hello there.
<br />
How do you do?
</p>
</>
);
}
```
Think of JSX as the secret superhero language. You can use an online converter to turn regular HTML into JSX if you need help translating.
---
## Adding Styles: Dressing Up Your Superheroes
In React, you specify a CSS class with `className`. It works the same way as the HTML `class` attribute. Let’s give our hero a stylish costume.
```jsx
<img className='avatar' />
```
Write the CSS rules in a separate file:
```css
/* In your CSS */
.avatar {
border-radius: 50%;
}
```
React doesn’t dictate how you add CSS files. Use a `<link>` tag in your HTML or follow the documentation for your build tool or framework.
---
## Displaying Data: Show Off Your Superhero Stats
JSX lets you mix JavaScript with HTML. Curly braces `{}` let you escape back into JavaScript to display data. For example, let’s display a user’s name:
```jsx
const user = { name: 'Hedy Lamarr' };
return <h1>{user.name}</h1>;
```
You can also use curly braces for attributes:
```jsx
const user = { imageUrl: 'https://i.imgur.com/yXOvdOSs.jpg' };
return <img className='avatar' src={user.imageUrl} />;
```
For complex expressions, like string concatenation:
```jsx
const user = {
name: 'Hedy Lamarr',
imageUrl: 'https://i.imgur.com/yXOvdOSs.jpg',
imageSize: 90,
};
export default function Profile() {
return (
<>
<h1>{user.name}</h1>
<img
className='avatar'
src={user.imageUrl}
alt={'Photo of ' + user.name}
style={{
width: user.imageSize,
height: user.imageSize,
}}
/>
</>
);
}
```
---
## Conditional Rendering: Superhero Decisions
React uses regular JavaScript for conditions. For example, you can use an `if` statement to include JSX conditionally:
```jsx
let content;
if (isLoggedIn) {
content = <AdminPanel />;
} else {
content = <LoginForm />;
}
return <div>{content}</div>;
```
For a more compact approach, use the conditional `?` operator:
```jsx
<div>{isLoggedIn ? <AdminPanel /> : <LoginForm />}</div>
```
Or use the logical `&&` operator when you don’t need an else branch:
```jsx
<div>{isLoggedIn && <AdminPanel />}</div>
```
---
## Rendering Lists: The Superhero Roster
Use JavaScript’s `map()` function to render lists of components. Imagine you have an array of products:
```jsx
const products = [
{ title: 'Cabbage', id: 1 },
{ title: 'Garlic', id: 2 },
{ title: 'Apple', id: 3 },
];
const listItems = products.map((product) => (
<li key={product.id}>{product.title}</li>
));
return <ul>{listItems}</ul>;
```
Each `<li>` needs a `key` attribute, usually from your data, like a database ID.
---
## Responding to Events: Superhero Actions
Respond to events by declaring event handler functions inside your components:
```jsx
function MyButton() {
function handleClick() {
alert('You clicked me!');
}
return <button onClick={handleClick}>Click me</button>;
}
```
Notice how `onClick={handleClick}` has no parentheses at the end. You only pass the function; React will call it when the event occurs.
---
## Updating the Screen: Superhero State
To remember some information, like how many times a button is clicked, add state to your component. First, import `useState` from React:
```jsx
import { useState } from 'react';
```
Declare a state variable inside your component:
```jsx
function MyButton() {
const [count, setCount] = useState(0);
function handleClick() {
setCount(count + 1);
}
return <button onClick={handleClick}>Clicked {count} times</button>;
}
```
`useState` gives you the current state (`count`) and a function to update it (`setCount`). Clicking the button updates the state and re-renders the component.
If you render the same component multiple times, each gets its own state:
```jsx
import { useState } from 'react';
export default function MyApp() {
return (
<div>
<h1>Counters that update separately</h1>
<MyButton />
<MyButton />
</div>
);
}
```
---
## Sharing Data Between Components: Superhero Team Coordination
Sometimes, components need to share data and update together. Move the state “upwards” to the closest common component. Here’s how:
First, move the state up from `MyButton` into `MyApp`:
```jsx
export default function MyApp() {
const [count, setCount] = useState(0);
function handleClick() {
setCount(count + 1);
}
return (
<div>
<h1>Counters that update together</h1>
<MyButton count={count} onClick={handleClick} />
<MyButton count={count} onClick={handleClick} />
</div>
);
}
```
Pass the state and click handler down as props:
```jsx
function MyButton({ count, onClick }) {
return <button onClick={onClick}>Clicked {count} times</button>;
}
```
When you click a button, `handleClick` updates the state in `MyApp`, which then passes the updated state to both `MyButton` components. This is called “lifting state up”.
---
## Conclusion
Congratulations! You’ve taken your first steps into the world of React and learned how to create, nest, style, and manage state in components. With these superpowers, you’re ready to build amazing, interactive web apps. Keep experimenting, stay curious, and remember: with great power comes great responsibility (and lots of fun coding adventures)!
Happy Coding!

Among these, Swift stands out for its simplicity, safety, and user-friendliness. In this blog post, we'll explore three key concepts in Swift that makes it the best option for ios development compared to JavaScript to provide a perspective from a beginner who is looking for the best language to use.
Swift's Safety and Type System
One of the most appealing features of Swift is its focus on safety. Swift is a type-safe language, which means it ensures that your code doesn’t mix values; such as numbers and strings. This safety feature helps prevent type-related errors and makes your code more predictable and dependable. In contrast, JavaScript will allow you to have mixed values in one declared variable. Such as an array, javascript will allow you to try to add a number with a string which will the output be a NAN, so far as with swift, it will auto correct. It will change the outlier to the corrected value.
// Swift can infer types, so you can also write:
let inferredNumbers = [1, 2, 3, 4, 5] // inferred as [Interger]
let inferredSum = inferredNumbers.reduce(0, +) // inferred as Int and sums up to 15
// However, JavaScript's dynamic typing can lead to unexpected results:
let mixedArray = [1, '2', 3, 4, 5];
let mixedSum = mixedArray.reduce((acc, num) => acc + num, 0); // Results in "012345" due to string concatenation
In the above example, Swift's type safety assures you that an array of numbers contains only integers, preventing type errors. In JavaScript it allows mixed values within arrays, which can lead to unexpected results or errors instead of numerical addition, unlike Swift. In this case, swift is way more dependable. Imagine not having to face any runtime delay errors. This Swift tool allows you to code more confidently and more efficiently.
Optionals is another powerful feature or tool in Swift that allows you to represent a missing value. This is useful when dealing with scenarios where a value is missing or not declared. JavaScript, on the other hand, uses null and undefined to represent the absence of a value, which can sometimes lead to errors or confusion. In Swift, you declare an optional by using a ? to the type. This means the variable can hold either a value of the specified type or ‘nil’ which is equal to no value.
// Swift Example
var optionalName: String? = "John"
optionalName = nil // valid because optionalName can hold a String or nil
// Unwrapping an optional safely using if-let
if let name = optionalName {
print("Hello, \(name)")
} else {
print("optionalName is nil")
}
In this example optionalName is declared as an optional String, so it can either hold a String value or be nil. Using the if let syntax, we safely unwrap optionalName. If it contains a value, we print it. Otherwise, we handle the case where it is nil.
Now lets compare it to a javascript example so you could see the beauty of optionals and how it can save you time and how efficient it is. In JavaScript, you can use null or undefined to represent the absence of a value. However, you need to check for these values explicitly.
// JavaScript Example
let name = "John";
name = null; // Can also be undefined
// Checking for null or undefined
if (name !== null && name !== undefined) {
console.log(`Hello, ${name}`);
} else {
console.log("name is null or undefined");
}
As you can see Swift's optionals provide a clear and safe way to handle missing values, reducing the likelihood of runtime errors. JavaScript’s approach requires more precise checks to ensure that a value is neither null nor undefined before using it.
2. Swift’s Visual and Interactive Toolsx
Swift's syntax is designed to be expressive and easy to read, making it an excellent choice for beginners. Its modern syntax makes common programming tasks easy to complete, especially in gaming development. Swift offers tools and frameworks for visualizing and developing games, particularly through Xcode and the SpriteKit framework. Swift Playgrounds is an interactive environment provided by Apple that makes learning Swift and experimenting with code fun and engaging. It’s particularly useful for visual learners and those new to programming. SpriteKit is a powerful framework provided by Apple specifically for 2D game development. It simplifies many aspects of game development, from rendering graphics to handling physics and user interactions. JavaScript also supports game development, particularly through frameworks like Phaser and libraries like Three.js for 3D graphics. However, the development environment is different and often less integrated than Swift's tools in Xcode and Playgrounds.
Swift’s tools like Playgrounds and frameworks like SpriteKit offer a highly integrated and user-friendly environment for game development. This makes Swift particularly appealing for beginners and visual learners, providing immediate feedback and simplifying the process of creating interactive and graphical applications. JavaScript, while also powerful for game development, often involves more setup and configuration, making Swift a more first choice option for many developers, specifically beginners.
3. Swift's User-Friendly Features
Swift was designed to be user-friendly, making it an excellent choice for beginners in iOS development. Its clear syntax, powerful libraries, and interactive environment make learning and using Swift a smooth experience, its not meant to be a difficult language at all. Also, Swift comes with a wide varitety of libraries and frameworks that simplify many common tasks. The Cocoa and Cocoa Touch frameworks, for instance, provide a wide range of functionalities for developing macOS and iOS applications. JavaScript also has libraries and frameworks, but the integration and consistency of Swift’s libraries with Apple's ecosystem provide a more seamless development experience. At the same time Swift’s standard library is extensive and powerful, providing a wide range of functionalities. Additionally, Swift has several frameworks that make developing for iOS and macOS efficient and enjoyable.
let fruits = ["Apple", "Banana", "Cherry"]
let uppercaseFruits = fruits.map { $0.uppercased() }
print(uppercaseFruits) // ["APPLE", "BANANA", "CHERRY"]
In this example, the map function is part of Swift’s standard library and allows you to transform each element in an array in a concise and readable manner.
Swift’s focus on safety, modern syntax, and user-friendly features makes it an excellent choice for iOS development. Comparing it to JavaScript highlights Swift's advantages in type safety, syntax, and learning tools, while also showing JavaScript’s flexibility and widespread use in web development. As I continue learning and experimenting with Swift and JavaScript, I’ll appreciate the strengths and trade-offs of each language, helping me become a more versatile developer. But, I think if i really deep dive into swift i’ll actually fall in love with it. My real goal is to do freelance work for business and create them ios apps.

1,883,302 | Exploring Inheritance & Polymorphism in OOP | Introduction In the previous post, we covered the basics of Object-Oriented Programming... | 27,662 | 2024-06-10T14:37:21 | https://dev.to/techtobe101/exploring-inheritance-polymorphism-in-oop-4hj0 | oop, techtobe101, beginners, programming | ### Introduction
In the previous post, we covered the basics of Object-Oriented Programming (OOP) and dove into abstraction and encapsulation. Now, let's explore the remaining two key concepts of OOP: inheritance and polymorphism.
### Understanding Inheritance
#### What is Inheritance?
Inheritance allows a class to inherit attributes and methods from another class. This promotes code reusability and establishes a natural hierarchy between classes. The class that inherits is called the subclass (or derived class), and the class being inherited from is the superclass (or base class).
#### How to Use Inheritance
Inheritance makes it easy to create new classes based on existing ones.
**Example:**
```python
class Vehicle:
def __init__(self, make, model):
self.make = make
self.model = model
def start_engine(self):
print("Engine started")
class Car(Vehicle):
def __init__(self, make, model, num_doors):
super().__init__(make, model)
self.num_doors = num_doors
def open_trunk(self):
print("Trunk opened")
```
`Car` inherits from `Vehicle`, adding its own properties and methods.
### Case Study: Creating a Vehicle Hierarchy
Imagine you are designing a system for different types of vehicles. By using inheritance, you create a base `Vehicle` class and extend it to specific types like `Car`, `Bike`, etc. This reduces redundancy and keeps the code organized.
#### How It Helps
This case study demonstrates how inheritance allows for code reuse and organization. It shows the efficiency of building on existing structures to handle more specific scenarios.
### Understanding Polymorphism
#### What is Polymorphism?
Polymorphism allows objects of different classes to be treated as objects of a common superclass. This means you can use a unified interface to work with different data types. Polymorphism is achieved through method overriding and method overloading.
#### How to Use Polymorphism
**Example:**
```python
class Animal:
def make_sound(self):
pass
class Dog(Animal):
def make_sound(self):
return "Bark"
class Cat(Animal):
def make_sound(self):
return "Meow"
def make_animal_sound(animal):
print(animal.make_sound())
dog = Dog()
cat = Cat()
make_animal_sound(dog) # Outputs: Bark
make_animal_sound(cat) # Outputs: Meow
```
Here, `make_animal_sound` can accept any `Animal` object, demonstrating polymorphism.
### Case Study: Handling Different Animals
Consider a program that needs to handle different animal sounds. By using polymorphism, you can create a general method to make animal sounds without worrying about the specific type of animal. This makes the code flexible and easy to extend.
#### How It Helps
This case study highlights the flexibility and power of polymorphism. It shows how you can write more generic and adaptable code, accommodating future changes and additions with ease.

### Introduction to Object-Oriented Programming (OOP)
Object-Oriented Programming (OOP) is a popular programming paradigm that organizes software design around data, or objects, rather than functions and logic. An object can be a data field with unique attributes and behavior. OOP simplifies complex software development by making it more modular, reusable, and maintainable.
### Key Concepts of OOP
There are four main concepts in OOP:
1. **Abstraction**
2. **Encapsulation**
3. **Inheritance**
4. **Polymorphism**
In this article, we will explore abstraction and encapsulation. Stay tuned for the next post in this series where we delve into inheritance and polymorphism.
### Understanding Abstraction
#### What is Abstraction?
Abstraction means simplifying complex systems by modeling classes appropriate to the problem. It involves focusing on relevant attributes and behaviors of an object while hiding unnecessary details. This way, developers can work with higher-level concepts without needing to understand all the underlying intricacies.
#### How to Use Abstraction
In OOP, you create classes to represent real-world objects but only include the details that matter.
**Example:**
```python
class Car:
def __init__(self, make, model):
self.make = make
self.model = model
def start_engine(self):
print("Engine started")
```
Here, `Car` is a class with essential details like `make`, `model`, and a method to start the engine.
### Case Study: Building a Car System
Consider a system where you need to manage different car models. By creating a `Car` class with essential properties and methods, you simplify how you interact with each car. You don’t need to know how each part of the car works, just how to use it.
#### How It Helps
This case study shows how abstraction hides complex details, making it easier to manage and use objects. It illustrates the power of structuring code to mirror real-world scenarios.
### Understanding Encapsulation
#### What is Encapsulation?
Encapsulation is the practice of bundling data (attributes) and methods (functions) that operate on the data into a single unit, or class. It also involves restricting access to some of the object's components, which is a means of preventing unintended interference and misuse of the data.
#### How to Use Encapsulation
Encapsulation protects the data inside an object from being altered in unexpected ways.
**Example:**
```python
class BankAccount:
def __init__(self, balance):
self.__balance = balance # Private attribute
def deposit(self, amount):
if amount > 0:
self.__balance += amount
def withdraw(self, amount):
if 0 < amount <= self.__balance:
self.__balance -= amount
def get_balance(self):
return self.__balance
```
Here, `__balance` is private and can only be changed through methods like `deposit` and `withdraw`.
### Case Study: Managing Bank Accounts
Think about managing bank accounts. By using encapsulation, you ensure that the balance can’t be directly modified. Users interact with the account through specific methods, which helps maintain the account’s integrity.
#### How It Helps
This case study shows how encapsulation protects data and ensures it is used correctly. It highlights the importance of controlling how data is accessed and modified.
### Conclusion
In this article, we've introduced the fundamental concepts of Object-Oriented Programming (OOP) and delved into the principles of abstraction and encapsulation. These concepts help in simplifying complex systems, making code more modular, reusable, and secure.
- **Abstraction** allows you to focus on the relevant details of an object while hiding unnecessary complexities.
- **Encapsulation** protects the internal state of an object by restricting direct access to some of its components.
By understanding and applying these principles, you can write more manageable and robust code. In the next article, we'll explore the remaining key concepts of OOP: inheritance and polymorphism. Stay tuned to learn how these principles further enhance your ability to write efficient and maintainable software.

1,883,347 | User Acceptance Testing (UAT): Meaning, Types & Process Explained | Use Acceptance Testing is the validation stage in the software development lifecycle that tests... | 0 | 2024-06-10T14:36:03 | https://dev.to/morrismoses149/user-acceptance-testing-uat-meaning-types-process-explained-2h4k | useracceptancetesting, testgrid | Use Acceptance Testing is the validation stage in the software development lifecycle that tests applications or programs in a real-world interface. It is the last stage before your app goes live. As the significance of app development rises, the need for proper UAT testing is highly coveted.
In this guide, we’ll talk about user acceptance testing (UAT), its importance, types, and a step-by-step process for performing UAT testing.
## What is User Acceptance Testing?
User Acceptance Testing, abbreviated as UAT, is an end-user or application testing that tests the application or software for real-world interactions with its intended audience or business representatives.
The goal of performing UAT is to test the software for its functionality, usability, security, and applicability in real-world scenarios. UAT is generally performed before the official release of the product.
## Importance of User Acceptance Testing
Just as important as it is to have a test drive before launching the automobile to the market, releasing software or an application program after real-world testing is equally important.
Hence, user acceptance testing is significant in reducing the errors that the users might face after the release. According to a survey, performing user acceptance testing can reduce post-release errors by 60%.
But that’s not the only reason. Let’s look at why UAT is important for the testers and developers:
**Cost-reduction**: Fixing the errors during the development process is much cheaper and easier rather than detecting and fixing them post-release.
**Improves final product**: When the developers release the product to a small part of the audience or within their organization, they receive critical feedback to improve product quality. Users can further know about optimizing the product as per users.
**Offers compliance**: UAT double-checks the laws and regulations set up by the local government. This is to ensure that the product offers compliance and follows regulations.
**Improves brand image**: Imagine your users giving feedback post-release about the bugs and glitches. UAT saves you from embarrassment, improves the brand image, and boosts customer loyalty.
Also, conducting user acceptance testing improves the overall user experience and saves you from the embarrassing monologue– “We are still new and evolving.”
## Types of User Acceptance Testing
UAT is a vast process and serves more than one purpose. Thus, it is divided into five different types deemed for different purposes:
**Beta testing**: Beta testing, also called field testing, is the real-world testing of the software by the selected end-users or stakeholders. It uses the real-world framework to create an environment in which the real users would work.
**Blackbox testing**: Also called behavioral testing, Blackbox testing tests the specific functionalities of the software without knowing the internal code. It focuses specifically on the input and output of the software program.
**Contract acceptance testing**: This testing is performed to ensure that the terms and conditions laid down in the service level agreement (SLA) are met. The product owners will only pay if the software follows specific requirements or criteria as laid in the contract.
**Alpha testing**: This is the first stage of UAT and is done during the software development stage. Alpha testing is performed by special testers who use various testing frameworks to conduct the test pre-release. The testers give feedback on the usability and compatibility of the software.
**Operational acceptance testing (OAT)**: As the name implies, OAT is a non-functional testing process that tests software or programs for stability, reliability, and operational efficiency.
## Pre-requisites of User Acceptance Testing
Before you start with the UAT test and set it up, there are a few prerequisites for the application to be qualified for the acceptance testing:
- Application code has to be completely developed.
- Unit testing, integration testing, and system testing should be done.
- The environment for UAT must be prepared.
- Business prerequisites must be present.
- There shouldn’t be any defects in the System Integration Test Phase.
- Regression testing must be performed with no major defects.
- All the defects found must be fixed and tested before UAT.
- The traceability matrix for all testing should be finished.
- Sign off mail of communication from the System Testing Team so that the system is ready for UAT execution.
- The only error acceptable before UAT is a cosmetic error.
## How to perform UAT testing?
Performing a user acceptance testing process takes a well-devised strategy.
### 1. Determine your business requirements
The first step is to identify and jolt down your business requirements. Requirements are the problems your software aims to solve for your target audience. There are two types of requirements that the testers take into consideration: business and functional requirements.
While the business requirements demonstrate the problem you solve, functional requirements include the technicalities of a program.
Based on these requirements, testers create test scenarios. Other documents for creating test scenarios:
These test scenarios are found from the following documents –
- Project charter
- Business use cases
- Process flow diagrams
- Business requirements documents
- System requirements specification
### 2. Create a UAT test plan
The strategy used to verify and ensure that the application meets its business requirements is outlined in the user acceptance testing plan. The [test plan](https://testgrid.io/blog/test-planning/) consists of various documents, which are explained below:
End-user testing strategy: It outlines various strategies that a user will use to perform the test. These include points like product description, test objectives, scope, standards, testing types, testers, user acceptance managers, and report methods.
Entry criteria: These are the criteria that the testing team lays before the testing begins. It checks if the product fulfills the pre-standards.
Exit criteria: These are the criteria set by the testing team to see if the product is ready to use. It includes all the pointers that determine the success of your product.
Test scenarios: Testers create these hypothetical conditions to test the viability of the product in the long run. It helps determine the common issues during the test.
### 3. Prepare test data & test environment
Preparing the test environment and test data is an essential step in conducting User Acceptance Testing (UAT).
The test environment should closely mimic the production environment where the software will be used, ensuring that the UAT accurately reflects real-world scenarios and conditions. Similarly, the test data should represent realistic user profiles, sample data sets, and any other data required for the specific testing scenarios.
Here’s what to keep in check for creating test data and test environment:
Hardware and software configurations: Set up the necessary hardware and software configurations to create a testing environment that closely resembles the production environment.
Network configurations: Configure the network settings to simulate the expected network conditions and connectivity for the end users.
Test data generation: Generate or gather the necessary test data that represents realistic user scenarios and activities. This may include user profiles, transaction data, or any other relevant data required for the UAT.
### 4. Choose the right UAT testing tools
Choosing the right User Acceptance Testing (UAT) testing tool is crucial for conducting an effective and efficient UAT process. A UAT testing tool provides features and functionalities that streamline the testing process, facilitate test case management, and enable effective communication and collaboration among the testing team and other project stakeholders.
When choosing a UAT testing tool, consider the following factors:
**Test case management**: Look for a tool that allows easy creation, organization, and management of test cases. The tool should provide features for assigning test cases to testers, tracking progress, and documenting test results.
**Bug tracking**: The tool should have built-in bug-tracking capabilities, allowing testers to report and track issues encountered during the UAT process.
**Collaboration and communication**: Choose a tool that facilitates clear communication and collaboration among the testing team, development team, and other stakeholders. It includes features such as comment threads, notifications, and real-time updates that can enhance collaboration and streamline communication.
**Integration capabilities**: Consider whether the tool can integrate with other project management and development tools used in your organization. It should also offer integration with tools such as project management software and bug tracking.
By choosing the right UAT testing tool, organizations can streamline the testing process, improve efficiency, and ensure accurate documentation and communication throughout the UAT process.
### 5. Execute and run the test
During this step, testers follow the defined test procedures and scenarios to validate the software’s functionality, performance, and usability. The key considerations for running UAT tests include:
**Execution of test scenarios**: Testers execute the predefined test scenarios, following the specified steps and interactions with the software.
**Recording test results**: Testers document the test results, recording any issues, observations, or unexpected behavior encountered during the testing process.
**Reporting issues**: Testers report any issues or bugs discovered during the testing process, providing detailed information about the problem, steps to reproduce it, and any supporting documentation or screenshots.
By running the planned tests, organizations can validate the software’s functionality, identify any issues or bugs, and ensure that the software meets the specified requirements and performs as expected.
### 6. Analyze test results
Lastly, Testers document the test results, providing detailed information about each test case, including the steps performed, expected results, and actual outcomes. It should track and report any issues or bugs discovered during the testing process, including detailed information about the problem and any supporting documentation or screenshots.
**User Acceptance Testing Checklist: **
- For performing the user acceptance testing, we have created a quick checklist to ensure that you tick mark all the requisites:
- Identify test cases for your reference
- Create a test scenario based on the test case
- Set out the pre-conditions to execute and create a test case
- Identify and note down the test data, such as login information, input values, etc.
- Let the testers write a report on the actual result of the performed test
- Compare the expected outcome with the actual outcome
- Include the additional screenshots or documents for supporting your tests
- Record the test date and track the progress of these tests
## UAT Best Practices
Before you begin with user acceptance testing, make sure to stick to the industry’s best practices.
Here are the quick best practices for performing UAT:
- Craft the UAT plan early in the project lifecycle. This plan should include comprehensive checklists to guide the entire testing process.
- Conduct pre-UAT sessions during the system testing phase to align expectations and define the precise scope of UAT. Testing should encompass the entire business flow from start to finish, simulating real-world scenarios and using actual data to ensure the system performs as expected under practical conditions.
- Adopt the perspective of a user who is completely unfamiliar with the system, focusing on usability to identify any potential areas of confusion or difficulty.
- After the completion of UAT, it is imperative to hold a feedback session. This allows testers to provide valuable insights and suggestions, which can be crucial for refining the system before it progresses to production.
- This structured approach not only streamlines the transition to the live environment but also enhances the overall quality and user satisfaction of the project.
## Challenges with User Acceptance Testing
Let’s look at the common challenges faced during the UAT testing process:
Old testing process: One of the challenges that testers face is the constant retests. The potential reason is the use of old testing methods like Excel sheets or a traditional/on-premise tool. This leads to a lack of visibility and an inefficient testing process.
**Undefined acceptance criteria**: There’s no success in UAT until you have clearly defined acceptance criteria. Testers should clearly lay out the acceptance criteria, agreed upon by all stakeholders.
Complex scenarios: Some test scenarios need specific testing conditions that may not be executed correctly by traditional testing tools. With traditional testing tools, executing the test scenarios may even require a higher learning curve.
**Time constraints**: Acceptance tests are often time-constrained, meaning testers have a fixed timeline for performing the tests. This limited time constraint leads to incomplete coverage of the software’s features and functionality.
**Adapting to changes**: Software projects are dynamic, with requirements and scope frequently changing. As new features are added, the testers have to adapt to these changes, which may be challenging without the right testing strategies
.

```
To send data, fetch() uses the body property for a post request to send data to the endpoint, while Axios uses the data property
The data in fetch() is transformed to a string using the JSON.stringify method
Axios automatically transforms the data returned from the server, but with fetch() you have to call the response.json method to parse the data to a JavaScript object
With Axios, the data response provided by the server can be accessed within the data object, while for the fetch() method, the final data can be named any variable | alamfatima1999 | |
1,882,947 | Handling Images on the Frontend Using FastAPI | In this tutorial, we'll look at how to use FastAPI to display static and dynamic images on the... | 0 | 2024-06-10T14:31:00 | https://geekpython.in/displaying-images-on-the-frontend-using-fastapi | fastapi, pyth, api | In this tutorial, we'll look at how to use FastAPI to display static and dynamic images on the frontend.
Displaying images on the frontend can be a time-consuming operation; it takes a significant amount of time and effort to create logic to show static and dynamic images. FastAPI includes certain classes and modules that can help you save time and effort when displaying images.
## Displaying static images
If you've dealt with the Python Flask or Django web frameworks, you'll know that in order to serve static files, we need to include them in the static folder established within the project's root directory.
The procedure is the same, however, the logic for displaying static images in FastAPI differs.
The following code will help us to display the ***static images*** on the frontend.
```python
# static_img.py
from fastapi import FastAPI
from fastapi.responses import HTMLResponse
from fastapi.staticfiles import StaticFiles
app = FastAPI()
app.mount("/imgs", StaticFiles(directory="imgs"), name='images')
@app.get("/", response_class=HTMLResponse)
def serve():
return """
<html>
<head>
<title></title>
</head>
<body>
<img src="imgs/g.png">
<h1>Hello World</h1>
</body>
</html>
"""
```
To serve static images or files, we utilised FastAPI's `StaticFiles` class. This class is derived directly from Starlette; we can simply import that class from `fastapi.staticfiles` instead of `starlette.staticfiles` for convenience.
We stored our static image inside the `imgs` directory present in the root directory and we passed this directory to the `StaticFiles()` instance and **mounted** it in the `/imgs` path.
> **Mounting** here means setting up or adding a completely independent application in a specific path, which will then take care of handling all the sub-paths.
Here,
`/img` - is a sub-path on which the sub-application will be mounted.
`directory='img'` - refers to the static directory where our static images or files will be stored.
`name='images'` - this name will be used by FastAPI internally or we can skip this also.
The path operation decorator `@app.get("/", response class=HTMLResponse)` was then created, and you'll notice that we passed `HTMLResponse`, which will assist in returning the HTML response directly from FastAPI.
The `response_class` will also be used to define the `media type` of the response and in this case, in the HTTP header, `Content-Type` will be set to `text/html`.
Then we created a **path operation function** called `serve()` and returned the HTML in which we passed our static image path(`"imgs/g.png"`) in the `src` attribute of the `<img>` tag.
Now run the server using the uvicorn.
```python
uvicorn static_img:app --reload
```
Here's the API response
If we see the API response in the Postman, then we'll see a raw HTML as a response by the FastAPI.
Due to `HTMLResponse` in the path operation decorator, the browser parses our HTML like it usually does for any HTML file.
## Another approach
This approach might be beneficial if you are working on a serious project and want your code to be more readable and manageable.
In this approach, we'll be using **jinja** and instead of using `HTMLResponse` we'll be using `Jinja2Templates` to render the HTML response.
> In order to use the `Jinja2Templates`, we need to install the `jinja2` library and it can be installed using the pip by running the command `pip install jinja2`.
```python
# files.py
from fastapi import FastAPI, Request
# The modules are directly coming from starlette
from fastapi.staticfiles import StaticFiles
from fastapi.templating import Jinja2Templates
app = FastAPI()
app.mount(
"/static", StaticFiles(directory="static"), name="static")
templates = Jinja2Templates(directory="templates")
@app.get("/")
def static(request: Request):
return templates.TemplateResponse("index.html", {"request": request})
```
The process is pretty much similar to the first approach but in this approach, we imported some more classes such as `Request` and `Jinja2Templates` from the `fastapi` and `fastapi.templating` modules, respectively.
Like in the first approach, we mounted the `StaticFiles(directory="static")` instance in a path `/static`.
Then using the `Jinja2Templates(directory="templates")`, we specified the directory called `templates` from where the FastAPI will look for the `.html` files and stored them inside the `templates` variable.
Then we created the path operation decorator `@app.get("/")` and followed by it created the path operation function called `static` and passed the `Request` class to the parameter `request`.
Then we returned the `TemplateResponse("index.html", {"request": request})`. In this case, we passed the `request` as part of the key-value pairs in the **Jinja2 context**. This will allow us to inject the dynamic content that we desire when the template is rendered.
Now write HTML code in the `index.html` file inside the **templates** directory.
```xml
<html>
<head>
<link href="{{ url_for('static') }}" />
<title>Serving Image Files Using FastAPI</title>
</head>
<body>
<img src="{{ url_for('static', path='assets/GP.png') }}" />
</body>
</html>
```
Just add the code `<link href="{{ url_for('static') }}" />` to link the directory named **static** as shown in the above code.
Then in the `src` attribute of the `<img>` tag, we specified the path to the static image using jinja like this `{{ url_for('static', path='assets/GP.png') }}`.
Now run the server using the command `uvicorn files:app --reload`.
Here's the response
If we see what we get when we send the request to the API using Postman.
We can include the same HTML as above in our `index.html` and get the same result but it won't be a good practice at all.
## Serving user-provided images
In this approach, we'll have a form where the user can enter an image that will be displayed on the frontend.
When a user uploads an image file, it is sent as **form data**, and we must install the following library to receive it.
```powershell
pip install python-multipart
```
The following code will be responsible for uploading and displaying the user-provided image.
```python
# dynamic.py
from fastapi import FastAPI, UploadFile, File, Request
from fastapi.templating import Jinja2Templates
import base64
app = FastAPI()
templates = Jinja2Templates(directory="templates")
@app.get("/")
def dynamic_file(request: Request):
return templates.TemplateResponse("dynamic.html", {"request": request})
@app.post("/dynamic")
def dynamic(request: Request, file: UploadFile = File()):
data = file.file.read()
file.file.close()
# encoding the image
encoded_image = base64.b64encode(data).decode("utf-8")
return templates.TemplateResponse(
"dynamic.html", {"request": request, "img": encoded_image})
```
The class `UploadFile` and function `File` from fastapi were imported into the code above to assist in handling the reading and uploading of the image file. We imported the `base64` library to handle image encoding and decoding.
We created a path operation decorator (`@app.get("/")`) and right below it created a path operation function called `dynamic_files` that will render the `dynamic.html` file on the path `"/"`.
Then we created a path operation decorator(`@app.post("/dynamic")`) to handle the **Post** request and then we created a path operation function called `dynamic` and passed `request: Request` and `file: UploadFile = File()`. Then we read the image file and stored it inside the `data` variable and finally closed the file.
Here, `file.file.read()` is equivalent to `UploadFile.file.read()`. `UploadFile` has a `file` attribute which is a file-like object and `read()` is a method also provided by `UploadFile` to read the bytes/characters of the image.
> If we would have defined the **asynchronous path operation function**, then we could read the file using `await file.read()`.
Now we've read the bytes of the image file and it needs to be encoded in a string that can be returned and passed to the template. If we look at the image's bytes, it would look like the following.
```powershell
xbd\x02\xacf\xb6\xaa\x02\x889\x95\xac6Q\x80\xa4<1\xcd\xef\xf7R\xc2\xb2<j\x08&6\xa8.s\x16M!i\xa8#\xe7RM$\x15\x00\x84\x81
...
x00\x00P\x1d\x01\x04\x00\x00\x00\x00\x00\xa8\x8e\x00\x02\x00\x00\x00\x00\x00T\xe7\xff\x03a\xbc\xbee\x93\xf6V\xfc\x00\x00\x00\x00IEND\xaeB`\x82'
```
`encoded_image = base64.b64encode(data).decode("utf-8")` will encode the bytes of the image file stored inside the `data` variable using the `utf-8` encoding into a string and the encoded string will be stored inside the `encoded_image` variable. Now, if we examine the encoded string, they will all appear to be random characters and resemble the following.
```powershell
+jYs7u5Zhy29PmXSh8aQtPim5Y4rC0OKzTQj5RYpzj2IBBCw3a7A0nEMRI1IbLj+uYSjUq/60lOuN3uaNuWvu85WK/RlHj67JyuW/H04oL16hCdtjvx6PFTD
...
I4AAAAAAAADVEUAAAAAAAIDqCCAAAAAAAEB1BBAAAAAAAKA6AggAAAAAAFAdAQQAAAAAAKiOAAIAAAAAAFTn/wNhvL5lk/ZW/AAAAABJRU5ErkJggg==
```
Then we returned the `dynamic.html` file and passed the variable `encoded_image` as a value of the key `"img"`.
### Writing template
`dynamic.html` file
```xml
<html>
<head>
<title>Rendering Dynamic Images Using FastAPI</title>
</head>
<body>
<form action="/dynamic" enctype="multipart/form-data" method="POST">
<input name="file" type="file" />
<input type="submit" />
</form>
{% if img %}
<h1>Rendered Image</h1>
<img src="data:image/jpeg;base64,{{ img }}" />
{% else %}
<h1>Image will be render here...</h1>
{% endif %}
</body>
</html>
```
In our `dynamic.html` file, we added a form tag that handles a **POST** request from the `"/dynamic"` URL, and we used the `enctype` attribute with the value `"multipart/form-data"` to handle file uploading through the form. Then, within the form, we added two **input** tags: one for selecting the image and one for submitting it.
Then we used jinja syntax to create an **if-else** condition and inserted an **img** tag with a `src` attribute containing our image. We passed `"data:image/jpeg;base64, img"` because we need to use this format to display base64 images in HTML.
### Testing API
Go to the URL `127.0.0.1:8000`.
We chose the image that will be displayed. The image will be displayed if we click the submit button.
**What if we want to save the user-provided image in a particular folder?**
### Saving user-provided images
To save user-provided images in a specific folder, assume we have a folder called **uploads** and want to save the images there.
```python
# dynamic.py
from fastapi import FastAPI, UploadFile, File, Request
from fastapi.templating import Jinja2Templates
import base64
app = FastAPI()
templates = Jinja2Templates(directory="templates")
@app.get("/")
def dynamic_file(request: Request):
return templates.TemplateResponse("dynamic.html", {"request": request})
@app.post("/dynamic")
def dynamic(request: Request, file: UploadFile = File()):
data = file.file.read()
# Image will be saved in the uploads folder prefixed with uploaded_
with open("uploads/saved_" + file.filename, "wb") as f:
f.write(data)
file.file.close()
# encoding and decoding the image bytes
encoded_image = base64.b64encode(data).decode("utf-8")
return templates.TemplateResponse(
"dynamic.html", {"request": request, "img": encoded_image})
```
We used the `open()` function and passed the path to our `uploads` folder with the name we want to prefix with the name of the image and opened it in `write` mode and then used `f.write(data)` to create an image within the uploads folder with the name ***saved\_xyz.png***.
### Testing
Run the server using `uvicorn dynamic:app --reload` and go to the URL `127.0.0.1:8000`.
## Conclusion
If you have worked with the Flask web framework, you may find it similar. FastAPI is a modern, high-performance web framework for building APIs using Python.
In this article, we've learned to display the static and user-provided(dynamic) images on the frontend using certain classes and modules from FastAPI. We saw two approaches for displaying static files on the frontend using FastAPI and then saw the process for displaying user-provided images and then the process for saving them in a particular folder.
Through this, we came across responses in FastAPI, requesting files, reading and uploading files, jinja templates and handling static files.

1,883,342 | Java Modal: A Step-by-Step Tutorial Even Your Grandma Can Follow! ;) | Hi there, fellow Java enthusiasts! Today, I'd like to do a step-by-step guide on how to use modals in... | 0 | 2024-06-10T14:29:22 | https://dev.to/jitskedh/react-modal-a-step-by-step-tutorial-even-your-grandma-can-follow--369o | Hi there, fellow Java enthusiasts! Today, I'd like to do a step-by-step guide on how to use modals in a Java-based web application using Spring Boot and Thymeleaf. Fear not, for I will guide you through each step with such clarity that even your dear grandma (or mom...) would be like, 'I could code that!' So, read along for a 'how to' on showing and hiding modals and handling form submissions. Ready? Let's dive into the world of Java modals!
- Step 1: Set Up Your Spring Boot Project
Assuming you already have a Spring Boot project set up, we'll skip straight to the next part.
- Step 2: Import Dependencies and Bootstrap
Our project depends on certain libraries, just like baking a cake requires flour. For this project, we will use Bootstrap, which provides a built-in modal component that makes creating and managing modals easier.
2.1 Add Bootstrap to Your Project
If you haven't already, you need to include Bootstrap in your project. You can do this by adding the following lines in the head of your template.
2.2
-Step 3: Let's define our component, in this case we'll call it 'formComponent
- Step 4: Setting op our state. We use state to keep track of the values that are being entered in the form fields. It's like having a smart assistant that remembers the user's input until we need it. With the useState hook, we create a state variable called values to store the form values and a function called setValues to update that state. This helps us make our app more interactive and responsive. The input values I use, you can change them to the ones you will use in your form.
- Step 5: Handling the change in our input fields Everytime we add a character in our input fields, we need to make sure that it's updating in our useState. That's why we create a function to handle this change and store it accordingly in the useState.
- Step 6: Handling the form submission So, whenever we filled out the whole form, we need to send it somewhere to the back for it to be processed and taken care of. (grandmas: Think about writing a letter, putting it in the mailbox and let the mailman take further care of it
- Step 7 (almost there): Showing and hiding the Modal The thing about a modal is that it gives you that extra sparkle on your project without having to create an entire new page for just a form. You open it, see the rest of the page in the background, but the focus lies on the Modal. Think of it in layers, your modal will be the top layer when opened, and the background will be the layer underneath.
So first we start by making 2 functions, one to open it and one to close it.
- Step 8: Rendering the component If we want to see the mdoal, we need to render it so that the user is able to see and interact with it.
This is where we start returning things, so that the user can see it.
In this example I see a '+' sign as a button to open the modal. We'll add a 'onClick' event that will trigger the 'showModal' function.
note the 'modal hidden' it's to style the modal. When 'hidden' we cannot see it. When we press the '+' button, the classname will be 'modal'.
- Step 9 (Be patient, 3 more to go): Implementing the content of the modal, when opened You can change my input with the input you'll need on your page. This step is were we will put content in our modals to display to the user.
- Step 10: Let's add our form input fields!
You can change the form input tyoes to whatever you need to use in ours, this is just an example of some you can use.
Note that we call the function 'handlesubmit' we created above to do what needs to be done when we press that button we're about to add!
- Step 11: FINAL STEP! Let's add our magic button who will handle everything without any other code needed..... just kidding, if only it were that simple on the back-end side...
Et voila, modal is ready in use. U can style the modal however you'd like. I used an overlay which blurred the layer below.
Below I put some screenshots of how my modal looks like in the project I used the modals in.
Thank you for reading!
Grandmas, I tried my best to explain it. I promise... but sometimes I don't even get half of what I'm doing ;)
Kindest regards,
Jitske De herdt

1,883,341 | Deep Dive into Web Session and Network Hijacking: Intercepting Data on Networks | Web session and network hijacking are critical security threats that can compromise personal and... | 0 | 2024-06-10T14:28:07 | https://dev.to/borisgigovic/deep-dive-into-web-session-and-network-hijacking-intercepting-data-on-networks-2ble | Web session and network hijacking are critical security threats that can compromise personal and organizational data integrity. These techniques allow attackers to intercept, view, and manipulate data transmitted over networks, leading to potential breaches of confidentiality. Understanding these methods provides insights into strengthening security protocols and mitigating risks associated with data interception.
## Understanding Web Session Hijacking
Web session hijacking, also known as cookie hijacking, involves the exploitation of valid web session IDs to gain unauthorized access to information on the network. When users authenticate to a website, they are often assigned a session cookie that keeps them logged in. If an attacker can acquire this cookie, they can impersonate the user.
### Operational Process:
**Session Sniffing:** Attackers use packet sniffing tools to capture unencrypted cookies as they travel over the network. Tools such as Wireshark or Tcpdump are used to monitor network traffic and capture data packets containing session IDs.
**Cross-Site Scripting (XSS)**: This involves injecting malicious scripts into web pages viewed by other users. If the script runs, it can send the user’s session cookies to the attacker.
**Session Fixation**: Here, the attacker tricks the user into logging in with a session ID known to the attacker. As soon as the user authenticates, the session becomes valid, and the attacker gains control.
### Preventive Measures:
- Implement HTTPS to secure data transmission.
- Use secure and HttpOnly cookie flags to protect cookies from being accessed by client-side scripts.
- Regularly update and patch web applications to mitigate vulnerabilities.
### Exploring Network Hijacking
Network hijacking involves taking over a network connection or part of the traffic to reroute data to the attacker’s location. It is more invasive than session hijacking as it can target entire networks.
#### Operational Process:
**ARP Spoofing:** Attackers send falsified ARP (Address Resolution Protocol) messages to a local network. This method associates the attacker’s MAC address with the IP address of another host, causing the traffic meant for that host to be sent to the attacker instead.
**DNS Hijacking:** This technique redirects queries to a malicious DNS server, leading users to fraudulent websites where attackers can intercept data.
**IP Spoofing:** Attackers send packets to a network pretending to be a trusted host to gain unauthorized access to the network.
#### Preventive Measures:
- Employ network security tools like ARPwatch to monitor ARP traffic and detect anomalies.
- Use DNSSEC (Domain Name System Security Extensions) to protect DNS queries.
- Implement packet filters to block packets with conflicting source addresses.
## Conclusion
Understanding and mitigating web session and network hijacking are crucial for maintaining the confidentiality and integrity of data across networks. By deploying robust security measures and remaining vigilant about potential vulnerabilities, individuals and organizations can protect themselves from these invasive attacks.
If you wish to learn more about the topic, it is recommended to attend a formal training class, such as the [Certified Ethical Hacker (CEHv12)](https://www.eccentrix.ca/en/courses/cybersecurity-and-cyberdefense/certified-ethical-hacker-cehv12-ec6154) course that explains in depth the concept and introduces a technical environment where you will be able to see the attack in motion. | borisgigovic | |
1,883,339 | How To Build a Simple GitHub Action To Deploy a Django Application to the Cloud | Continuous integration and continuous delivery (CI/CD) capabilities are basic expectations for modern... | 0 | 2024-06-10T14:25:13 | https://dev.to/heroku/how-to-build-a-simple-github-action-to-deploy-a-django-application-to-the-cloud-4395 | Continuous integration and continuous delivery (CI/CD) capabilities are basic expectations for modern development teams who want fast feedback on their changes and rapid deployment to the cloud. In recent years, we’ve seen the growing adoption of GitHub Actions, a feature-rich CI/CD system that dovetails nicely with cloud hosting platforms such as Heroku. In this article, we’ll demonstrate the power of these tools used in combination—specifically how GitHub Actions can be used to quickly deploy a Django application to the cloud.
## A Quick Introduction to Django
[Django](https://www.djangoproject.com/) is a Python web application framework that’s been around since the early 2000s. It follows a model-view-controller (MVC) architecture and is known as the “batteries-included” web framework for Python. That’s because it has lots of capabilities, including a strong object-relational mapping (ORM) for abstracting database operations and models. It also has a rich templating system with many object-oriented design features.
Instagram, Nextdoor, and Bitbucket are examples of applications built using Django. Clearly, if Django is behind Instagram, then we know that it can scale well. (Instagram hovers around being the fourth most visited site in the world!)
Security is another built-in feature; authentication, cross-site scripting protection, and CSRF features all come out of the box and are easy to configure. Django is over 20 years old, which means it has a large dev community and documentation base—both helpful when you’re trying to figure out why something has gone awry.
Downsides to Django? Yes, there are a few, with the biggest one being a steeper learning curve than other web application frameworks. You need to know parts of everything in the system to get it to work. For example, to get a minimal “hello world” page up in your browser, you need to set up the ORM, templates, views, routes, and a few other things. Contrast that with a framework like Flask (which is, admittedly, less feature-rich), where less than 20 lines of code can get your content displayed on a web page.
## Building Our Simple Django Application
If you’re not familiar with Django, [their tutorial](https://docs.djangoproject.com/en/5.0/intro/tutorial01/) is a good place to start learning how to get a base system configured and running. For this article, I’ve created a similar system using a PostgreSQL database and a few simple models and views. But we won’t spend time describing how to set up a complete Django application. That’s what the Django tutorial is for.
My application here is different from the tutorial in that I use PostgreSQL—instead of the default SQLite—as the database engine. The trouble with SQLite (besides poor performance in a web application setting) is that it is file-based, and the file resides on the same server as the web application that uses it. Most cloud platforms assume a stateless deployment, meaning the container that holds the application is wiped clean and refreshed every deployment. So, your database should run on a separate server from the web application. PostgreSQL will provide that for us.
The source code for this mini-demo project is available in [this GitHub repository](https://github.com/CapnMB/django-heroku-github-actions).
### Install Python dependencies
After you have cloned the repository, start up a virtual environment and install the Python dependencies for this project:
```
(venv) ~/project$ pip install -r requirements.txt
```
### Set up Django to use PostgreSQL
To use PostgreSQL with Django, we use the following packages:
- [psycopg2](https://pypi.org/project/psycopg2/) provides the engine drivers for Postgres.
- [dj-database-url](https://pypi.org/project/dj-database-url/) helps us set up the database connection string from an environment variable (useful for local testing and cloud deployments).
In our Django app, we navigate to mysite/mysite/ and modify settings.py (around line 78) to use PostgreSQL.
```
DATABASES = {"default": dj_database_url.config(conn_max_age=600, ssl_require=True)}
```
We’ll start by testing out our application locally. So, on your local PostgreSQL instance, create a new database.
```
postgres=# create database django_test_db;
```
Assuming our PostgreSQL username is dbuser and the password is password, then our DATABASE_URL will look something like this:
```
postgres://dbuser:password@localhost:5432/django_test_db
```
From here, we need to run our database migrations to set up our tables.
```
(venv) ~/project$ \
DATABASE_URL=postgres://dbuser:password@localhost:5432/django_test_db\
python mysite/manage.py migrate
Operations to perform:
Apply all migrations: admin, auth, contenttypes, movie_journal, sessions
Running migrations:
Applying contenttypes.0001_initial... OK
Applying auth.0001_initial... OK
Applying admin.0001_initial... OK

Applying auth.0012_alter_user_first_name_max_length... OK
Applying movie_journal.0001_initial... OK
Applying sessions.0001_initial... OK
```
### Test application locally
Now that we have set up our database, we can spin up our application and test it in the browser.
```
(venv) ~/project$ \
DATABASE_URL=postgres://dbuser:password@localhost:5432/django_test_db\
python mysite/manage.py runserver
…
Django version 4.2.11, using settings 'mysite.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
```
In our browser, we visit [http://localhost:8000/movie-journal](http://localhost:8000/movie-journal). This is what we see:
We’re up and running! We can go through the flow of creating a new journal entry.
Looking in our database, we see the record for our new entry.
```
django_test_db=# select * from movie_journal_moviejournalentry;
-[ RECORD 1 ]+-------------------------------------------------------------

```
Our application is working. We’re ready to deploy. Let’s walk through how to deploy using GitHub Actions directly from our repository on commit.
## The Power of GitHub Actions
Over the years, GitHub Actions has built up a large library of jobs/workflows, providing lots of reusable code and conveniences for developers.
With CI/CD, a development team can get fast feedback as soon as code changes are committed and pushed. Typical jobs found in a CI pipeline include style checkers, static analysis tools, and unit test runners. All of these help enforce good coding practices and adherence to team standards. Yes, all these tools existed before. But now, developers don’t need to worry about manually running them or waiting for them to finish.
Push your changes to the remote branch, and the job starts automatically. Go on to focus on your next coding task as GitHub runs the current jobs and displays their results as they come in. That’s the power of automation and the cloud, baby!
### Plug-and-play GitHub Action workflows
You can even have GitHub create your job configuration file for you. Within your repository on GitHub, click Actions. You’ll see an entire library of templates, giving you pre-built workflows that could potentially fit your needs.
Let’s click on the Configure button for the Pylint workflow. It looks like this:
```

pylint $(git ls-files '*.py')
```
This configuration directs GitHub Actions to create a new workflow in your repository named Pylint. It triggers a push to any branch. It has one job, build, that runs the latest Ubuntu image. Then, it runs all the steps for each of the three different versions of Python specified.
The steps are where the nitty-gritty work is defined. In this example, the job checks out your code, sets up the Python version, installs dependencies, and then runs the linter over your code.
Let’s create our own GitHub Action workflow to deploy our application directly to Heroku.
## Deploying to Heroku via a GitHub Action
Here’s the good news: it’s easy. First, [sign up for a Heroku account](https://www.googleadservices.com/pagead/aclk?sa=L&ai=DChcSEwiXtdaw-5mFAxXBLdQBHZJ5BJkYABABGgJvYQ&ase=2&gclid=Cj0KCQjwzZmwBhD8ARIsAH4v1gXSRHbXjzlc9n8gUY1x-3mgbp4AV3KsQznkWamh3S91LfOBGbOO0IYaArHsEALw_wcB&ohost=www.google.com&cid=CAESV-D2oE_02dbv0jHQ_lty1qqK8Lx5as8Sx0CGWY4yAwXX-iO_prj5-K-woiZ95Jwj1VyouwGSiQnd0ORFU-fyr8keQSYrY-2msOiEEe6x87QjOio6iFfYcw&sig=AOD64_07cvmaddkY6Suzb9QJWReiRtqCSQ&q&nis=4&adurl&ved=2ahUKEwivwc-w-5mFAxXbJUQIHTVzAGsQqyQoAHoECAoQEw) and [install the Heroku CLI](https://devcenter.heroku.com/articles/heroku-cli).
### Login, create app, and PostgreSQL add-on
With the Heroku CLI, we run the following commands to create our app and the PostgreSQL add-on:
```
$ heroku login
$ heroku apps:create django-github
Creating ⬢ django-github... done
https://django-github-6cbf23e36b5b.herokuapp.com/ | https://git.heroku.com/django-github.git
$ heroku addons:create heroku-postgresql:mini --app django-github
Creating heroku-postgresql:mini on ⬢ django-github... ~$0.007/hour (max $5/month)
Database has been created and is available
! This database is empty. If upgrading, you can transfer
! data from another database with pg:copy
```
### Add Heroku app host to allowed hosts list in Django
In our Django application settings, we need to update the list of [ALLOWED_HOSTS](https://docs.djangoproject.com/en/5.0/ref/settings/#allowed-hosts), which represent the host/domain names that your Django site can serve. We need to add the host from our newly created Heroku app. Edit mysite/mysite/settings.py, at around line 31, to add your Heroku app host. It will look similar to this:
```
ALLOWED_HOSTS = ["localhost", "django-github-6cbf23e36b5b.herokuapp.com"]
```
Don’t forget to commit this file to your repository.
### Procfile and requirements.txt
Next, we need to add a Heroku-specific file called Procfile. This goes into the root folder of our repository. This file tells Heroku how to start up our app and run migrations. It should have the following contents:
```
web: gunicorn --pythonpath mysite mysite.wsgi:application
release: cd mysite && ./manage.py migrate --no-input
```
Heroku will also need your requirements.txt file so it knows which Python dependencies to install.
### Get your Heroku API key
We will need our Heroku account API key. We’ll store this at GitHub so that our GitHub Action has authorization to deploy code to our Heroku app.
In your Heroku account settings, find the auto-generated API key and copy the value.
Then, in your GitHub repository settings, navigate to Secrets and variables > Actions.
On that page, click New repository secret. Supply a name for your repository secret and. Then, paste in your Heroku API key and click Add secret.
Your list of GitHub repository secrets should look like this:
## Create the job configuration file
Let’s create our GitHub Action workflow. Typically, we configure CI/CD jobs with a YAML file. With GitHub Actions, this is no different.
To add an action to your repository, create a .github subfolder in your project, and then create a workflows subfolder within that one. In .github/workflows/, we’ll create a file called django.yml. Your project tree should look like this:
```
.
├── .git
│ └── …
├── .github
│ └── workflows
│ └── django.yml
├── mysite
│ ├── manage.py
│ ├── mysite
│ │ ├── …
│ │ └── settings.py
│ └── …
├── Procfile
└── requirements.txt
```
Our django.yml file has the following contents:
```
name: Django CI
on:
push:
branches: [ "main" ]
jobs:
release:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- uses: akhileshns/heroku-deploy@v3.13.15
with:
heroku_api_key: ${{ secrets.HEROKU_API_KEY }}
heroku_app_name: "<your-heroku-app-name>"
heroku_email: "<your-heroku-email>"
```
This workflow builds off of the [Deploy to Heroku Action](https://github.com/marketplace/actions/deploy-to-heroku) in the GitHub Actions library. In fact, using that pre-built action makes our Heroku deployment simple. The only things you need to configure in this file are your Heroku app name and account email.
When we commit this file to our repo and push our main branch to GitHub, this kicks off our GitHub Action job for deploying to Heroku. In GitHub, we click the Actions tab and see the newly triggered workflow. When we click the release job in the workflow, this is what we see:
Near the bottom of the output of the deploy step, we see results from the Heroku deploy:
When we look in our Heroku app logs, we also see the successful deploy.
And finally, when we test our Heroku-deployed app in our browser, we see that it’s up and running.
Congrats! You’ve successfully deployed your Django action to Heroku via a GitHub Action!
## Conclusion
In this article, we set up a simple Django application with a PostgreSQL database. Then, we walked through how to use GitHub Actions to deploy the application directly to your Heroku on commit.
Django is a feature-rich web application framework for Python. Although for some cloud platforms, it can take some time to get things configured correctly, that’s not the case when you’re deploying to Heroku with GitHub Actions. Convenient off-the-shelf tools are available in both GitHub and Heroku, and they make deploying your Django application a breeze.

1,883,337 | Electrifying Software: Electron | In the world of software development, the need for building versatile and high-performance... | 0 | 2024-06-10T14:21:40 | https://dev.to/ajgamer/electrifying-software-electron-119c | beginners, opensource, electron | In the world of software development, the need for building versatile and high-performance applications has always been present. Enter Electron, a powerful framework that has redefined native app development with a unique blend of web technologies and native capabilities. But what exactly makes Electron stand out, and why should developers consider it for their next project?
## What is Electron?
Electron is an open-source framework developed by GitHub that allows developers to build cross-platform desktop applications using HTML, CSS, and JavaScript. It leverages the power of Node.js for backend operations and Chromium for rendering the front end, creating a seamless environment where web and native development converge.
## _Key Advantages_
- **Cross-Platform Compatibility:**
One of the most significant advantages of Electron is its ability to create applications that run smoothly on Windows, macOS, and Linux. This means that developers can write their code once and deploy it across multiple operating systems, saving time and resources.
- **Web Technology Familiarity:**
For developers well-versed in web development, Electron provides a familiar playground. The use of HTML, CSS, and JavaScript means there's no need to learn new programming languages or paradigms, significantly lowering the entry barrier.
- **Vast Database:**
Electron's database is large, with numerous libraries and tools available to enhance development. From frameworks like React to Node.js modules, developers have a plethora of resources at their disposal to build applications.
- **Active Community and Support:**
With a large and active community, Electron developers can find ample support and resources online. This community-driven approach ensures continuous improvement and a wealth of knowledge to tap into when encountering challenges.
## How Electron Works
At its core, Electron comprises three main components: Chromium, Node.js, and the Electron framework itself.
- **Chromium:**
Electron uses Chromium, the open-source browser project that also powers Google Chrome, to render the application's front end. This ensures that the app's UI behaves consistently across different platforms.
- **Node.js:**
On the backend, Electron employs Node.js, allowing developers to use JavaScript for server-side scripting. This integration makes it possible to manage file systems, handle network operations, and perform other backend tasks directly within the application.
- **Electron Framework:**
The Electron framework bridges the gap between Chromium and Node.js, providing APIs that facilitate communication between the front end and backend. This includes features like window management, notifications, and more.
**Building an Electron App: _A Quick Overview_**
Creating an Electron app is relatively straightforward. Here’s a basic outline of the steps involved:
- **Setting Up the Environment:**
First, you'll need [Node.js](https://nodejs.org/en) and _npm_ (Node Package Manager) installed on your machine. With these tools in place, you can create a new project directory and initialize it with `npm init`.
- **Installing Electron:**
Next, install Electron as a development dependency using npm:
```
npm install electron --save-dev
```
- **Creating the Main Script:**
In the root of your project directory, create a main.js file. This script will serve as the entry point for your Electron application. Here’s a simple example:
```
const { app, BrowserWindow } = require('electron');
function createWindow() {
const win = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
nodeIntegration: true,
},
});
win.loadFile('index.html');
}
app.whenReady().then(createWindow);
app.on('window-all-closed', () => {
if (process.platform !== 'darwin') {
app.quit();
}
});
app.on('activate', () => {
if (BrowserWindow.getAllWindows().length === 0) {
createWindow();
}
});
```
- **Creating the HTML File:**
Next, create an index.html file in the same directory:
```
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Hello Electron</title>
</head>
<body>
<h1>Hello, Electron!</h1>
<script>
console.log('Hello from the renderer process!');
</script>
</body>
</html>
```
- **Running the App:**
Finally, add a start script to your package.json file:
```
"scripts": {
"start": "electron ."
}
```
Short and sweet right? Now, you can run your app using:
```
npm start
```
## Real-World Applications of Electron
Electron has been used to create some of the most popular desktop applications in the market today. Examples include:
- **Visual Studio Code:** A powerful, lightweight code editor developed by Microsoft.
- **Slack:** A collaboration hub for work that combines messaging, tools, and files.
- **Spotify:**
The desktop client for the popular music streaming service.
These applications demonstrate the versatility and capability of Electron in delivering high-quality, performant applications that users love.
**Conclusion**
Electron has revolutionized native app development by combining the flexibility of web technologies with the power of native desktop capabilities. Its cross-platform compatibility, ease of use, and large database make it an excellent choice for developers looking to create modern, high-performance desktop applications.

In the ever-evolving battle between cybercriminals and security professionals, understanding the tactics of adversaries is crucial. One such tactic is reconnaissance, an essential method employed by ethical hackers to gather vital information about target systems. This process forms the backbone of defensive strategies aimed at fortifying security infrastructures.
###What is Reconnaissance?
Reconnaissance, the initial phase of ethical hacking, involves gathering information about a target system through methods like footprinting, scanning, and enumeration. This step is indispensable for identifying vulnerabilities and potential access points, thus forming the foundation for penetration testing and enhancing security measures.
###Types of Reconnaissance
Reconnaissance in cybersecurity is classified into two main types: active and passive. Active reconnaissance involves direct interaction with the target system using tools like automated scanning, ping, and netcat. While it is more accurate and quicker, it is also noisier and more likely to be detected. A common example is port scanning, which identifies open ports on a computer to find potential vulnerabilities. On the other hand, passive reconnaissance gathers information without direct interaction, ensuring the target remains unaware. This type uses non-intrusive methods like Wireshark and Shodan to collect data from web searches and open-source intelligence. Wireshark, for instance, analyzes network traffic discreetly to gather valuable insights.
###How Does Reconnaissance Work?
Reconnaissance involves systematically collecting information about a network, including OS platforms, running services, file permissions, user accounts, and trust relationships. Ethical hackers follow a structured approach with steps like collecting preliminary information, identifying active machines, pinpointing access points, and creating a network map. This comprehensive profile increases the likelihood of identifying and addressing security weaknesses.
###Fundamentals of Reconnaissance
Seven key principles guide effective reconnaissance: making reconnaissance a continuous habit, deploying assets dynamically, aligning efforts with objectives, reporting precise and timely information, maintaining flexibility in operations, staying vigilant and engaged with threats, and acting swiftly to adapt to new information.
###Preventing Reconnaissance Attacks
Organizations can employ several strategies to prevent reconnaissance attacks. Conducting penetration testing to assess network vulnerabilities, using passive scanning tools and vulnerability scanners, and implementing SIEM solutions to detect scanning activities are critical steps. Employing stateful firewalls as a first line of defense and logging multiple connection attempts to monitor for suspicious activities further strengthens security. Aligning these measures with the MITRE ATT&CK Framework can further enhance defense strategies against potential reconnaissance threats.
###Conclusion
Reconnaissance is a double-edged sword, used by both attackers and defenders in the cyber realm. Understanding and leveraging reconnaissance allows cybersecurity professionals to identify and mitigate vulnerabilities, transforming a commonly offensive tool into a robust defensive strategy. By staying vigilant and proactive, organizations can stay ahead of cyber threats and protect their digital assets effectively. | clouddefenseai | |

In my previous articles, we learned about [containers](https://mariusniemet.me/a-gentle-introduction-to-containerization/) and how to create a stack for your [multi-container app using docker-compose](https://mariusniemet.me/containerize-your-mutil-container-app-with-docker-compose/). However, managing a multitude of containers can quickly become complex and unwieldy. This is where container orchestration comes into play. In this article, we will do a quick overview of the challenges that can be handled using an orchestration tool and then introduce Kubernetes, its role, and its components.
## What is container orchestration?
Once the containers are running, container orchestration tools automate life cycle management and operational tasks based on the container definition file, including:
- Deployment: your app is running in production and you want to deploy a new version without downtime.
- Scaling up: you have a peak load at a certain time of the day you want your app to handle that load by automatically adding instances of your app and servers.
- Scaling down: once the load has decreased the resources should be removed as well to avoid paying for unnecessary machines.
- Performance and Health: your app is made by multiple services communicating with each other, if one of them fails you should be able to notice and restart the service.
- Networking: exposing your services to the end user and handling the communication between the internal services with load balancing.
Even though this article will be focused on Kubernetes I want to mention that there are multiple container orchestration platforms such as [Mesos](https://mesos.apache.org/), [Docker Swarm](https://docs.docker.com/engine/swarm/), [OpenShift](https://docs.openshift.com/), [Rancher](https://www.rancher.com/), [Hashicorp Nomad](https://www.nomadproject.io/), etc.
## What is Kubernetes?
Kubernetes is a platform built by Google for container orchestrations. It aims to provide automated solutions for all the challenges mentioned before such as deployment, horizontal scaling, performance and health monitoring of the application, etc.
Kubernetes has multiple components that work together in order to orchestrate the app's load.
### Control plane
The control plane is responsible for running the Kubernetes cluster and it has its components.
Each component plays a role within the control plane:
- **etcd:** it’s a fault-tolerant and distributed key-value store that stores the cluster state and configuration.
- **API Server:** exposes the API used to interact with the cluster and the internal and external requests.
- **Scheduler:** is responsible for scheduling new pod creation and deciding in which worker node they will be run.
- **Controller:** It monitors the current state of the cluster and takes action to move that state to the desired state. It runs separate processes such as node controller, replica, Endpoint, service account, and token controller.
- **Cloud manager controller:** it can embed cloud-specific control logic, such as accessing the cloud provider’s load balancer service. It enables you to connect a Kubernetes cluster with the cloud provider's API. Additionally, it helps decouple the Kubernetes cluster from components that interact with a cloud platform, so that elements inside the cluster do not need to be aware of the implementation specifics of each cloud provider.
### Node
Nodes are virtual or physical machines responsible for running the application instances. Each node has a bunch of components running in it.
- **Kube Proxy:** it communicates with the Kubernetes control plane and allows network communication to pods between pods.
- **Kubelet:** it’s the tool responsible for running the state on each node, checking container health, and taking action.
- **Container runtime:** each node needs a container runtime to run containers, it can be docker or any other runtime.
- **Container Networking:** Container networking enables containers to communicate with hosts or other containers.
- **Pod:** it’s the smallest unit Kubernetes allows to interact with. Inside a POD we can run containers.
### Cluster
A Kubernetes cluster is the collection of the control plane with its worker nodes. A cluster can scale up to 5000 worker nodes.
## Kubernetes Objects
Kubernetes objects are persistent entities in the Kubernetes system. They represent the state of the cluster, once an object is created and applied Kubernetes will work to ensure that the current state is equal to the desired.
- **Volume:** At its core, a volume is a directory, possibly with some data in it, accessible to the containers in a pod.
- **Service:** it’s a method used to expose an app within the cluster.
- **Namespace:** it’s a way to create an isolated collection of resources within the cluster. Names of resources need to be unique within a namespace, but not across namespaces.
and pods which we have already introduced in the previous section.
## Helm package manager
With Kubernetes, Helm serves as a package manager, working similarly to npm in Node.js and yum in Linux. Helm deploys charts as complete and packaged Kubernetes applications, which include pre-configured versioned application resources. It is possible to deploy different chart versions by using different configuration sets.
## Conclusion
In conclusion, we have explored the basics of container orchestration, the fundamentals of Kubernetes, its architecture, and its key components. We have also covered its basic objects and introduced Helm the package manager.
I hope you enjoy this article as much as I enjoyed writing it.

In this article, we'll delve deeper into the CAMARA project to understand its implications and what it means for the telecom industry.
## What is CAMARA?
Imagine this: the giants of telecommunications and technology, assembling like The Avengers, to establish a new standard aimed at harmonizing and exposing new network capabilities to create a seamless user experience. Say no more. Welcome to CAMARA!
CAMARA is an open-source project within the Linux Foundation that hosts the API standards and develops and tests the APIs. The project collaborates closely with the GSMA Operator Platform Group to align API requirements.
The name CAMARA originates from the Greek word for "arched roof," symbolizing the collaboration or alliance of multiple entities under one vision.
## How Does it Work?
The members (participants, coordinators, contributors, etc.) of the CAMARA project are organized into subprojects and working groups. Although it may sound similar, there are some differences.
### Subprojects
A subproject is where topics related to each API are discussed, including how to document and describe the API or develop and test it. Some examples of subprojects include [SIM Swap](https://github.com/camaraproject/SimSwap), [Device status](https://github.com/camaraproject/DeviceStatus), or [Number Verification](https://github.com/camaraproject/NumberVerification).
Members of each subproject meet virtually from time to time and organize their work around a GitHub repository and a mailing list. All repositories contain the same structure, making it easy to find information:
* The `documentation/MeetingMinutes` folder stores all minutes from previous meetings, during which decisions about the API's behavior are made.
* The `code/API_definitions` contains the OpenAPI specification of the API in YAML format.
### Working groups
The [working groups](https://github.com/camaraproject/WorkingGroups) typically address common topics across all subprojects. Some examples of working groups are the [API Backlog](https://github.com/camaraproject/WorkingGroups/blob/main/APIBacklog/documentation/APIbacklog.md), which manages the lifecycle of the API proposals, the Marketing group, responsible for promoting the APIs, or the Commonalities group, where common topics relevant to all APIs are discussed (e.g. authorization, documentation, or guidelines)
Just like the subprojects, members of the working groups use a [GitHub repository](https://github.com/camaraproject/WorkingGroups/) and a mailing list to coordinate their activities.
If you're curious about the project's structure and the roles of its participants, check out the [Project Structure and Roles](https://github.com/camaraproject/Governance/blob/main/ProjectStructureAndRoles.md) documentation page.
## API Lifecycle
One of the most interesting activities of the project is to maintain the lifecycle of the APIs.
Everything starts with the [API onboarding](https://github.com/camaraproject/Governance/blob/main/documentation/API-onboarding.md), where companies can submit a new API proposal outlining a high description of the API (what it does with some examples), along with its technical and commercial viability.
The API Backlog working group will evaluate the proposal and, if they approve it, they'll endorse the proposal to be sent to the steering committee for final approval. If all goes well, the API proposal will be transformed into an actual subproject, which will begin receiving contributions and ideas using the mechanisms described above.
Once the API specification is stable enough, the implementation will be deployed and tested in one or more operator networks. The deployment can be used in production environments if the tests prove successful.
## Conclusion
The CAMARA project sets an important milestone in the telco industry in terms of coordination and cooperation. The open structure of the project facilitates tracking and understanding some decisions taken behind each API.
The resources and documentation already generated by the project members are extensive. Be sure to explore their [GitHub](https://github.com/camaraproject) repositories and [Wiki](https://wiki.camaraproject.org/).

Einleitung
In der heutigen ästhetischen Medizin hat sich die Laserbehandlung als eine unverzichtbare Methode etabliert, um das Erscheinungsbild der Haut zu verbessern. Dank fortschrittlicher Technologien sind moderne Lasersysteme präziser und sicherer als je zuvor. Besonders in Zürich, einer Stadt, die für ihre hochwertigen medizinischen Dienstleistungen bekannt ist, erfreuen sich Laserbehandlungen großer Beliebtheit. Sie bieten eine minimal-invasive und risikoarme Alternative zu herkömmlichen chirurgischen Eingriffen und versprechen gleichzeitig ein natürliches und verjüngtes Aussehen.
Minimale Invasivität und Sicherheit
Einer der größten Vorteile der Laserbehandlung ist ihre minimal-invasive Natur. Im Gegensatz zu chirurgischen Eingriffen erfordert die Lasertherapie keine Schnitte oder Nähte. Dies reduziert das Risiko von Komplikationen und Infektionen erheblich. Moderne Lasergeräte sind zudem mit fortschrittlichen Sicherheitstechnologien ausgestattet, die eine präzise Steuerung und Anpassung der Behandlungsparameter ermöglichen. Dies stellt sicher, dass die Behandlung gezielt auf die individuellen Bedürfnisse der Patienten abgestimmt wird.
Förderung der Kollagen- und Elastinbildung
Ein zentraler Aspekt der Laserbehandlung ist die Stimulation der Kollagen- und Elastinproduktion in der Haut. Kollagen und Elastin sind essentielle Proteine, die für die Festigkeit und Elastizität der Haut verantwortlich sind. Mit zunehmendem Alter nimmt die natürliche Produktion dieser Proteine ab, was zu Falten und schlaffer Haut führt. Durch die gezielte Anwendung von Laserenergie wird die Bildung neuer Kollagen- und Elastinfasern angeregt, was zu einer natürlichen Straffung und Verdichtung des Gewebes führt. Das Ergebnis ist ein verjüngtes Hautbild und eine verbesserte Hautqualität.
Fraktionierte Lasertherapie
Die fraktionierte Lasertherapie ist eine der beliebtesten Formen der Laserbehandlung Zürich. Diese Methode verwendet mikroskopisch kleine Laserstrahlen, die in die Haut eindringen und gezielt winzige Bereiche behandeln. Dies stimuliert den Heilungsprozess der Haut und fördert die Neubildung von Kollagen. Die fraktionierte Lasertherapie ist besonders effektiv bei der Behandlung von Aknenarben, Pigmentstörungen und feinen Linien.
Laser Skin Resurfacing
Das Laser Skin Resurfacing ist eine weitere weit verbreitete Methode zur Hautverjüngung. Bei dieser Behandlung wird die oberste Hautschicht entfernt, um die darunter liegende frische und gesunde Haut freizulegen. Dies hilft, Hautunreinheiten, Sonnenschäden und feine Falten zu reduzieren. Die Erholungszeit nach dem Laser Skin Resurfacing ist minimal, und die Ergebnisse sind oft schon nach einer einzigen Sitzung sichtbar.
Nicht-ablativer Laser
Der nicht-ablative Laser ist eine schonende Behandlungsoption, die keine Schädigung der oberen Hautschicht verursacht. Stattdessen dringt die Laserenergie tief in die Haut ein, um die Kollagenproduktion zu stimulieren und die Hautstruktur zu verbessern. Diese Methode ist ideal für Patienten, die eine sanfte Behandlung mit minimaler Ausfallzeit wünschen.
Beratung und Hautanalyse
Der erste Schritt einer **[Laserbehandlung Zürich](https://skinatelier.ch/laserbehandlungen-zuerich/)** beginnt mit einer ausführlichen Beratung und Hautanalyse. Der behandelnde Arzt beurteilt den Hautzustand des Patienten, bespricht die gewünschten Ergebnisse und erklärt die verschiedenen Behandlungsmöglichkeiten. Basierend auf dieser Analyse wird ein individueller Behandlungsplan erstellt.
Durchführung der Behandlung
Am Behandlungstag wird die Haut zunächst gründlich gereinigt. Je nach Art der Lasertherapie kann eine betäubende Creme aufgetragen werden, um eventuelle Unannehmlichkeiten zu minimieren. Der Laser wird dann präzise auf die zu behandelnden Hautbereiche gerichtet. Die Dauer der Behandlung variiert je nach Größe des Behandlungsareals und Art der Lasertherapie, liegt jedoch in der Regel zwischen 30 Minuten und einer Stunde.
Nachbehandlung und Erholung
Nach der Laserbehandlung kann die Haut leicht gerötet oder geschwollen sein, ähnlich wie bei einem leichten Sonnenbrand. Diese Symptome klingen jedoch meist innerhalb weniger Tage ab. Es wird empfohlen, die Haut gut zu pflegen und Sonnenschutz zu verwenden, um den Heilungsprozess zu unterstützen und die besten Ergebnisse zu erzielen. Die meisten Patienten können bereits am nächsten Tag ihre normalen Aktivitäten wieder aufnehmen.
Risiken und Nebenwirkungen
Obwohl Laserbehandlungen im Allgemeinen als sicher gelten, können sie wie jede medizinische Behandlung auch Risiken und Nebenwirkungen mit sich bringen. Zu den möglichen Nebenwirkungen gehören vorübergehende Rötungen, Schwellungen und Hautreizungen. In seltenen Fällen können auch Pigmentveränderungen oder Narbenbildung auftreten. Es ist wichtig, dass die Behandlung von einem qualifizierten und erfahrenen Facharzt durchgeführt wird, um das Risiko von Komplikationen zu minimieren.
Fazit
Die Laserbehandlung Zürich bietet eine revolutionäre Möglichkeit zur Hautverjüngung und Verbesserung der Hautstruktur. Mit fortschrittlichen Technologien und minimalen Risiken stellen Lasertherapien eine effektive und schonende Alternative zu chirurgischen Eingriffen dar. Durch die Förderung der Kollagen- und Elastinbildung sorgt die Laserbehandlung für eine natürliche Straffung und Verdichtung des Gewebes, was zu einem verjüngten Teint und einer verbesserten Hautqualität führt. Für alle, die eine nicht-chirurgische Methode zur Hautverjüngung suchen, stellt die Laserbehandlung Zürich eine ausgezeichnete Wahl dar.

## 4. **Compute Services**
### 4.1.<u>Virtual Machine (VM - IaaS) </u>
- It's analogue to a Server. A single physical machine has been divided into slices and you can to rent a single slice of it;
- Even if the VM is turned off, billing will be still charged. Billings won't be charged only if you delete the machine;
- If you have a public IP assigned to your VM, when you delete it, don't forget to delete public IP too. Otherwise, you'll continue being charged.
- <u>Must belong at least to 1 subnet using a Network Interface Card (NIC) - some VMs have 1 or more NIC and can connect to 1 or more subnet;</u>
- Can be assigned to a public IP which can be accessed from outside Azure.
* <u>Standalone Server:</u> You don't share any resources/services.
* <u>Virtualization:</u> Some resources/services are shared with other VMs.
Microsoft provides over 700 images (CPU, RAM, IOPS...) os types to choose.
### 4.1.2.<u>VM Scaling Sets (VMSS)</u>
- <u>Scale Up</u>: To increase the size of a VM;
- <u>Scale Out</u>: Add more VMs and have them working together (it's the most common scenario);
- <u>Scale Sets</u>: Group of VM that can grow and shrink based on a predefined rule (base on monitoring demand, time/schedule...);
- A Scale Sets fills the elasticity requirement of cloud compute;
- Usually can handle over 100 VMs per Single Set, but you can configure to increase that to 1000 VMs per Single Set;
- To deploy a VMSS you have to provision at least 2 VMs running the exact same code;
- Can manage groups of VMs as one unit;
- With a Load Balancer in front of it to direct traffic randomly to one of VMs.
- <u>Availability Set</u>: Availability Sets allow you to tell Azure which virtual machines are identical, so that Azure will keep them apart physically inside the datacenter. This helps when there are either expected or unexpected downtime, by increasing the chances that one issue does not affect all VMs in a single Availability Set.
### 4.2.<u>App Services (Web Apps - PaaS)</u>
- Upload your code and configure it into Azure;
- You can download the software that you want, but only what is supported by Microsoft;
- You can access servers through FTP to get your files;
- You can do A/B tests using deployments slots.
### 4.3.<u>Azure Container Instance (ACI)</u>

In the software development ecosystem, there is often friction between software developers and technical writers when it comes to creating and contributing to software documentation. One reason for this issue is that these two key players often use different methods for publishing their work. However, wouldn't it be beneficial if software developers could collaborate with technical writers in writing and managing software documentation?
The answer is **YES**, it is possible, but only with the **Docs-as-Code** approach. To understand how this can be achieved, let's dive deeper into what the Docs-as-Code approach entails.
In this post, you will learn about managing technical documentation in the same way a developer handles code, known as the Doc-as-Code (DAC) approach, and why team leaders and technical writers should adopt it.

## Docs-as-Code (DaC)
In technical writing, many approaches have been used by technical writers for writing, publishing, and maintaining technical documentation. Previously, technical writers used Database CMS tools such as WordPress, Hippo, and others, which did not encourage contributions from other users, such as developers, to the documentation.
It was not until October 19, 2000, that [Tom Preston-Werner](https://tom.preston-werner.com/), co-founder of GitHub, had an idea about the Docs-as-Code (DaC) approach.
In a blog post, [Blogging Like a Hacker](https://tom.preston-werner.com/2008/11/17/blogging-like-a-hacker.html), he states,
> "What would happen if I approached blogging from a software
> development perspective? What would that look like?"
The question above gave birth to the **Docs-as-Code** approach.
### What is Docs-as-Code?
Docs-as-code is an approach to writing and publishing documentation with the same tools and processes developers use to create code.
In short, the DaC approach uses the same systems, processes, and workflows with docs as you do with programming code.
### Processes of the Docs-as-Code approach
The Docs-as-Code approach comprises:
- **Writing reStructuredText or Markdown** in plain text files.
- **Developing the documentation website using an open-source static site generator** like [Sphinx](https://www.sphinx-doc.org/en/master/) or [MkDocs](https://www.mkdocs.org/) to build the files locally through the command line, rather than using a commercial program.
- **Working with files using a text editor** that supports docs-as-code, such as Visual Studio Code.
- **Keeping track of the documentation in a version control repository** (usually a Git repo), similar to how developers store programming code, rather than keeping docs in another space like Dropbox or a SharePoint drive. Additionally, you can store the docs in the same repository as the code itself.
- **Working with other writers using version control systems** such as Git to track changes in the plain text files instead of collaborating through large content management systems or SharePoint-like check-in/check-out sites.
- **Automating the site build process with continuous delivery** to build the documentation website when you update the repository, rather than manually publishing and transferring files from one place to another.
- **Executing validation scripts** to check for broken links, improper terms/styles, and formatting errors instead of spot-checking the content manually.
- **Managing docs using processes similar to engineers** (e.g., agile scrum), such as dividing documentation tasks in an issue manager (such as JIRA), allocating the issues to bi-weekly sprints, and informing stakeholders about the tasks finished (showing demos).
#### Tools used in Docs-as-Code
There are many tools that you can use with the Docs-as-Code approach. They include:
- Plain text markup such as [reStructuredText](https://docutils.sourceforge.io/docs/ref/rst/directives.html) or Markdown. We recommend you use reStructuredText. You can read this [article](https://idratherbewriting.com/2016/10/28/markdown-or-restructuredtext-or-dita-choosing-format-tech-docs/) first to help decide which markup language to use in your project.
- Static site generators like [Sphinx](https://www.sphinx-doc.org/en/master/).
- Text editors that support Docs-as-Code, such as [Visual Studio Code](https://code.visualstudio.com/).
- [Git](https://git-scm.com/) for version control and [GitHub](https://github.com) for storing remote versions of the repository.
- Continuous integration and continuous delivery tools like [GitHub Actions](https://docs.github.com/en/actions).
- The [Python](https://python.org/) programming language.
### The Benefits and Limitations of Docs-as-Code
Using the docs-as-code approach has both merits and demerits, which you must consider before adopting it into your project. Below are some benefits and limitations of using the docs-as-code approach.
#### Benefits
- **Collaboration with developers:** The docs-as-code approach improves collaborative efforts between developers and technical writers, enabling the provision of better and more accurate documentation. Often, writing documentation for a particular product is complex enough to necessitate involvement from developers for both writing and reviewing. As a result, implementing the docs-as-code approach encourages developers to contribute to the product documentation, allowing technical writers to focus on documenting how to use the product effectively.
- **Integration with other infrastructures:** You can incorporate the docs-as-code workflow into existing company or project infrastructures. Most companies rely on certain infrastructures to operate, and any new approach they adopt must integrate seamlessly with those existing infrastructures. The docs-as-code approach is suitable for such companies because of its flexibility, making it easy to integrate into any existing infrastructure. For example, [useblocks GmbH](https://useblocks.com), a German software solution company, has developed a [Sphinx-Needs Enterprise](https://useblocks.com/sphinx-needs-enterprise/) plugin that integrates [Sphinx-Needs](https://sphinxcontrib-needs.readthedocs.io/en/latest/) into company-specific tool environments. This synchronization of data between Sphinx-Needs and existing tools like Jira, Azure, GitHub, and CodeBeamer ensures the utilization of data from other existing tools with Sphinx-Needs, resulting in the generation of meaningful documentation.
- **Contribution from the open-source community:** The docs-as-code approach embraces external contributions from other technical writers, subject-matter experts, and users. While not all documentation projects are public, most allow other contributors to participate in their development, aiding in the discovery and resolution of issues in the documentation. Although these contributions need to be reviewed to ensure they align with your style guide and content strategy, the input provided by the community helps enhance your documentation.
- **Continuous Delivery:** In the docs-as-code approach, you can rebuild your output by simply committing and pushing content into a Git repository. The repository will detect the changes and trigger a build and publishing job, a process known as **Continuous Delivery**. You can edit multiple pages and send your changes to your production repository. When the changes reach your production repository, an automatic content build and deploy process runs on your repo, quickly transferring the output files to your server. You no longer need to FTP files to a server or follow a manual deployment process. A quick update and a Git commit are all you need to change your documentation. This helps reduce the pressure of publishing and deploying docs and also encourages developers to write and contribute to the documentation. Continuous delivery is the feature that makes docs-as-code so much more effortless (with publishing) compared to other solutions.
- **Delivery of updated and validated documentation:** Using the DaC approach, you can deliver up-to-date documentation to your users, enabling them to access accurate content. For example, most Sphinx documentation sites provide information about the date of the last changes. This information informs readers if they are reading outdated content or not. Additionally, we can use validation scripts in our docs-as-code approach to ensure we validate each content before publishing it. Validation scripts, such as checking broken links or verifying if the content meets the style guide, help us identify mistakes so we can correct them.
- **Integration with A.I. tools:** You can use A.I. tools to assist in drafting and reviewing documentation, enhance documentation search capabilities with tools like [Algolia DocSearch](https://docsearch.algolia.com/) and [TypeSense DocSearch](https://typesense.org/docs/guide/docsearch.html), and provide a support assistant chatbot like [DocsBot AI](https://docsbot.ai/) that helps software users access information and troubleshoot problems.
- **Content reuse:** Content reuse is the ability to include content from one document in another. Most docs-as-code static site generators support content utilization using templating languages like [Jinja](https://palletsprojects.com/p/jinja/) to enable documentation writers to use conditional filtering, content reuse, variables, and more when writing documentation.
#### Limitations
Here's the revised version with corrections:
The following are some limitations of docs-as-code:
- **Learning Curve:** The DaC approach requires writers to be familiar with software development tools like Git. Additionally, most technical writers use Markdown to write their documentation. Although the Markdown language is easy to learn and use, it lacks standards. The many flavors of Markdown syntax make it challenging to use the same Markdown text across all Markdown-supported static site generators.
> **Note**
>
> Instead of using the Markdown language, we recommend you use the [reStructuredText](https://docutils.sourceforge.io/docs/ref/rst/directives.html) language.
- **Tool Integration:** Integrating documentation tools into existing workflows can be tricky at times if best practices are not implemented.
- **Cultural Shifts:** Both technical writers and developers must agree to the use of this approach for successful implementation.
- **Localization:** Localization in docs means adapting your documentation to the needs of a particular language. Having your documentation in multiple languages is a requirement for a documentation site that aims to convey its message to a particular language and culture. Most docs-as-code static site generators do not support translation (except [Sphinx](https://www.sphinx-doc.org/en/master/)). While we write most technical documentation in one language, it is appropriate if these docs-as-code tools support localization.
- **Hard to prevent Git disasters in public technical documentation:** Using version control systems, like Git in the docs-as-code workflow, requires some training and a code of conduct to prevent Git mistakes in public documentation.
- **No PDFs:** For most technical documentation, it is necessary to generate PDF documents for the entire documentation project or single pages in the documentation. PDF is possible, just not usually an out-of-the-box feature.
> **Note**
>
> You can try out either the [Sphinx-PDF Generate](https://isolveit.github.io/sphinx-pdf-generate/) or the [Sphinx-SimplePDF](https://sphinx-simplepdf.readthedocs.io/) plugin if you are using Sphinx-Doc.
## Conclusions
In most companies, technical writers adopt the docs-as-code approach to write both external and internal technical documentation. Although there are challenges with the approach, if the right measures and practices are put in place, both the developers and technical writers will benefit hugely from adopting the docs-as-code approach to document up-to-date content for their software users.
Below are some **best practices** I would recommend if you want to adopt the docs-as-code approach in your projects:
- **Early Integration:** Integrate the DaC approach into your documentation project early in the development process.
- **Automated Testing:** Employ automated testing tools like PyTest, linters, and formatters in CI/CD tools like GitHub Actions to ensure documentation accuracy.
- **Consistent Formats:** Analyze and select one or more text-based formats to use in your project and provide standards on the text-based formats selected for ease of collaboration.
- **Use third-party software and collaborative tools:** Utilize third-party tools to ensure writers focus on writing and delivering documentation quickly and to ensure collaborative editing and review.
- Additionally, **create a docs-as-code ecosystem that is open to all contributors**. If users contribute to the documentation, it enables a workflow where writers and users feel ownership of documentation and work together to deliver essential information.
There is more to building a proper **Docs-as-Code** ecosystem, and I hope to find and share such knowledge with everyone.

<h2><span style="font-weight: 400;">Finding the Best Deals on Cheap Car Rentals</span></h2>

<ol>
<li style="font-weight: 400;"><strong>Book in Advance:</strong><span style="font-weight: 400;"> Planning ahead and booking your rental car in advance can often result in lower rates. Many rental companies offer early booking discounts or promotional offers, so it's beneficial to reserve your vehicle as soon as your travel dates are confirmed.</span></li>
<li style="font-weight: 400;"><strong>Compare Prices:</strong><span style="font-weight: 400;"> Don't settle for the first rental company you come across. Take the time to compare prices from different providers to find the most competitive rates. Online platforms and comparison websites can be valuable tools for this purpose.</span></li>
<li style="font-weight: 400;"><strong>Check for Discounts:</strong><span style="font-weight: 400;"> Keep an eye out for special promotions, discounts for loyalty program members, or coupon codes that can further reduce your rental costs. These discounts may be available through the rental company's website or third-party booking platforms.</span></li>
<li style="font-weight: 400;"><strong>Opt for Off-Peak Times:</strong><span style="font-weight: 400;"> Rental rates can vary depending on the time of year and demand. Consider renting during off-peak seasons or weekdays when prices tend to be lower due to reduced demand.</span></li>
</ol>
<h2><span style="font-weight: 400;">Tips for a Smooth Rental Experience</span></h2>
<ol>
<li style="font-weight: 400;"><strong>Read the Terms and Conditions:</strong><span style="font-weight: 400;"> Before booking a rental car, carefully read the terms and conditions, including insurance coverage, fuel policies, and any additional fees. Understanding these details can prevent surprises and ensure a smooth rental experience.</span></li>
<li style="font-weight: 400;"><strong>Inspect the Vehicle:</strong><span style="font-weight: 400;"> Upon receiving the rental car, inspect it thoroughly for any existing damages or issues. Take note of any scratches, dents, or mechanical issues and inform the rental company to avoid liability disputes later.</span></li>
<li style="font-weight: 400;"><strong>Drive Responsibly:</strong><span style="font-weight: 400;"> Follow traffic rules and regulations while driving in Dubai. Familiarize yourself with local traffic laws and parking regulations to avoid fines or penalties during your rental period.</span></li>
<li style="font-weight: 400;"><strong>Return on Time:</strong><span style="font-weight: 400;"> Be punctual when returning the rental car to avoid late fees. Check the fuel level and cleanliness of the vehicle before handing it back to the rental company.</span></li>
</ol>
<h2><span style="font-weight: 400;">Conclusion</span></h2>
<p><span style="font-weight: 400;">In conclusion, opting for cheap car rental Dubai services can offer a convenient and budget-friendly way to explore the city's attractions and enjoy a flexible travel experience.

As a tiny web dev team with just the two of us, we recently had to deal with the fun challenge of finding a new teamie. This whole deal really made us realize that throwing a bunch of new people into the mix right away isn't always the best move. It's like everyone thinks, "more peeps, less work, yay!" But, in reality, it can totally backfire.
The thing is, when you go on a hiring spree and add a bunch of new folks too quickly, you're actually setting yourself up for more drama than a reality TV show. You've got more bureaucracy, a higher chance of miscommunication, and everyone leaning on each other like we're playing a giant game of Jenga. This can lead to projects turning into a hot mess and deadlines going out the window.
Onboarding and getting everyone up to speed is obviously important, but it's not just about teaching the newbies the ropes. You've gotta make sure everyone's got their own stuff to do, so it's fair and the work gets done right. If you don't, you'll have some peeps bored out of their minds and others drowning in work, which is a total no-go for team vibes.
For us, the struggle was real because I was basically the only one who could handle the training gig. My buddy, bless their heart, wasn't quite up to the task, which meant I had to juggle it all. This isn't ideal, because it puts a lot of pressure on me and might not give the new folks the best start.
So, trying to get a bunch of new hires up and running at the same time, especially with the situation we had, is like trying to solve a Rubik's Cube blindfolded. It's way better to add just one new person at a time, get them all cozy and confident, and then let them help out with the next round of newbies. That way, everyone learns and grows together, and you don't end up with any weak links in the chain.
Companies get all excited about growing super fast and hiring a ton of people, but that's like trying to build a house without a blueprint. It's bound to fall apart. What you really wanna do is take it slow, hire one dev at a time, and make sure they're fully ready to rock before you bring in the next one. That way, you build a solid team that actually works well together.
In the end, it's not about adding a bunch of bodies to the team as quickly as you can. It's about growing in a way that makes everyone stronger, smarter, and ready to tackle whatever comes next. Each new person should be like a Lego block that fits just right and helps build a cooler castle. Do it carefully, and you'll end up with a team that's unstoppable.
