1,904,276 | How to use guardrail to protect PII information with AWS Bedrock Converse API, Lambda and Python! - Anthropic Haiku | Generative AI - Has Generative AI captured your imagination to the extent it has for me? Generative... | 0 | 2024-06-28T13:51:28 | https://dev.to/bhatiagirish/how-to-use-guardrail-to-protect-pii-information-with-aws-bedrock-converse-api-lambda-and-python-anthropic-haiku-1323 | aws, generativeai, amazonbedrock, bedrockconverseapi | Generative AI - Has Generative AI captured your imagination to the extent it has for me?
Generative AI is indeed fascinating! The advancements in foundation models have opened up incredible possibilities. Who would have imagined that technology would evolve to the point where you can generate content summaries from transcripts, have chatbots that can answer questions on any subject without requiring any coding on your part, or even create custom images based solely on your imagination by simply providing a prompt to a Generative AI service and foundation model? It's truly remarkable to witness the power and potential of Generative AI unfold.
In this article, I am going to show you how to build a serverless GenAI solution to create call center transcript summary via a Rest API, Lambda and AWS Bedrock Converse API. I have posted an article with detail steps on creating a GenAI solution for summarizing the call center transcripts by passing a transcript file that contains the conversation between a call center support staff and a customer.
**However, in this example, I will further extend it by adding the function to protect the customer PII information so that this information is abstracted from the response being returned by Amazon Bedrock Converse API to the end consumer of the API.**
Examples of PII (Personal Identifiable Information) - SSN, Account Number, Phone, Email, Address etc.
Amazon Bedrock is fully managed service that offers choice of many foundation models like Anthropic Claude, AI21 Jurassic-2 , Stability AI, Amazon Titan and others.
I will use recently released Anthropic Haiku foundation model and will invoke it via Amazon Bedrock Converse API.
**Let's revisit what Amazon Converse API is for and why it is needed?**
You might be wondering why there's a need for another API when Bedrock already supports invoking models for large language models (LLMs). The challenge that the Converse API aims to address is the varying parameters required to invoke different LLMs. It offers a consistent API that can call underlying Amazon Bedrock foundation models without requiring changes in your code. For example, your code can call Anthropic Haiku, Anthropic Sonnet, or Amazon Titan just by changing the model ID without needing any other modifications!
While the API specification provides a standardized set of inference parameters, it also allows for the inclusion of unique parameters when needed.
As of May 2024, the newly introduced Converse API does not support embedding or image generation models.
**What is Amazon Converse API guardrail?**
Generative AI guardrails, provided by various generative AI solutions, are one of my favorite functional areas to read about, validate, and prototype! These guardrails transform a generative AI solution into a Responsible AI solution by ensuring that responses stay within predefined boundaries. Examples include abstracting Personally Identifiable Information (PII) or preventing an API or chatbot from providing information from restricted areas, such as account details, investment advice, or any other sensitive data defined by the organization.
Amazon Bedrock initially supported guardrails for invoking foundational models. As of June 2024, similar support has been extended to the Amazon Bedrock Converse API.
I will implement these guardrails in a previously completed project involving the transcript summary for a call center. In this use case, the Generative AI response to the end consumer will abstract any Personally Identifiable Information.
**Guardrail Policies**
The Amazon Bedrock Guardrail feature allows you to configure various filters, providing responsible boundaries for the responses generated by your AI solution. These guardrails help ensure that the outputs are appropriate and align with your requirements and standards.
**Content Filters**
Content Filters across 6 categories
Hate
Insults
Sexual
Violence
Misconduct
Prompt Attack
Filters can be set to None, Low, Medium, High.
**Denied Topics**
You can specify filter for the topic that API should not respond to!
**Word Filter**
You can specify words that you want filter to act on before providing a response!
**Sensitive Information Filter**
Filter to either block or mask the Personal Identifiable Information.
Amazon Bedrock allow provides a way to configure the message provided back to the user if input or the response in violation with the guardrail configured policies. For example, if Sensitive information filter configured to block a request with account number, then, you can provide a customize response letting user know that request cannot be processed since it contains a forbidden data element.
Let's review our use cases:
- There is a transcript available for a case resolution and conversation between customer and support/call center team member.
- A call summary needs to be created based on this resolution/conversation transcript.
- An automated solution is required to create call summary.
- An automated solution will provide a repeatable way to create these call summary notes.
- Increase in productivity as team members usually work on documenting these notes can focus on other tasks.
- Guardrail should be configured so that PII information is not displayed in the response.
I am generating my lambda function using AWS SAM, however similar can be created using AWS Console. I like to use AWS SAM wherever possible as it provides me the flexibility to test the function without first deploying to AWS cloud.
Here is the architecture diagram for our use case.
**Create a SAM template**
I will create a SAM template for the lambda function that will contain the code to invoke Bedrock Converse API along with required parameters and a prompt. Lambda function can be created without the SAM template however, I prefer to use Infra as Code approach since that allow for easy recreation of cloud resources. Here is the SAM template for the lambda function.
**Create a Lambda Function**
The Lambda function serves as the core of this automated solution. It contains the code necessary to fulfill the business requirement of creating a summary of the call center transcript using the Amazon Bedrock Converse API. This Lambda function accepts a prompt, which is then forwarded to the Bedrock Converse API to generate a response using the Anthropic Haiku foundation model. Now, Let's look at the code behind it.
**Build function locally using AWS SAM**
Next build and validate function using AWS SAM before deploying the lambda function in AWS cloud. Few SAM commands used are:
SAM Build
SAM local invoke
SAM deploy
**Bedrock Invoke Model Vs. Bedrock Converse API**
**Bedrock InvokeModel**
**Bedrock Converse API**
**Validate the GenAI Model response using a prompt**
Prompt engineering is an essential component of any Generative AI solution. It is both art and science, as crafting an effective prompt is crucial for obtaining the desired response from the foundation model. Often, it requires multiple attempts and adjustments to the prompt to achieve the desired outcome from the Generative AI model.
Given that I'm deploying the solution to AWS API Gateway, I'll have an API endpoint post-deployment. I plan to utilize Postman for passing the prompt in the request and reviewing the response. Additionally, I can opt to post the response to an AWS S3 bucket for later review.
> I am using Postman to pass transcript file for the prompt.
> This transcript file has a conversation between call center employee (John) and customer (Girish) about a request to reset the password due to the locked account.
> John: Hello, thank you for calling technical support. My name is John and I will be your technical support representative. Can I have your account number, please?
> Girish: Yes, my account number is 213-456-8790.
> John: Thank you. I see that you have locked your account due to multiple failed attempts to enter your password. To reset your password, I will need to ask you a few security questions. Can you please provide me with the answers to your security questions?
> Girish: Sure, my security questions are: What is your favorite color? and What is your favorite food?
> John: Please can you provide your zip code?
> Girish: Yes, my zip code is 43215.
> John: one final question, Please confirm your email address.
> Girish: my email is gbtest@gmailtest.com.
> John: Great, thank you. I will now reset your password and send you an email with instructions on how to log in to your account. Please check your email in a few minutes.
> Girish: Thank you so much for your help.
> John: You're welcome. Is there anything else I can assist you with today?
> Girish: No, that's all for now. Thank you again for your help.
> John: You're welcome. Have a great day!
**Review the response returned by Generative AI Foundation Model**
As you can note in the response above, GenAI responses does not include the PII information.
Let's look at the response once guardrail policy is updated to block the PII data.
**Response with blocked data**
Above is the response when policy is updated to block if PII contains account number.
With these steps, a serverless GenAI solution to create call center transcript summary via a Rest API, Lambda and AWS Bedrock Converse API has been successfully completed. Python/Boto3 were used to invoke the Bedrock API with Anthropic Haiku.
**As was demonstrated, with Converse API, guardrail was used to implement a policy to control the GenAI response and abstract and block the PII data!**
A guardrail was created to remove the PII information from the response. Also guardrail config was updated to validate that account number when configured for blocking, will be blocked.

In problem 7.6.3, known as the **Dining-Philosophers Problem**, I found myself both amused and intrigued by its inherent complexity and practical implications. Without spoiling the details, I found the scenario both amusing and thought-provoking. I invite you to discover it firsthand within the pages of the book I mentioned previously, 'OPERATING SYSTEM CONCEPTS with JAVA.
**7.6.3 The Dining-Philosophers Problem**
The dining-philosophers problem illustrates a scenario where five philosophers sit at a circular table, each alternating between thinking and eating. The table is set with five single chopsticks, with each philosopher needing two chopsticks to eat. Philosophers pick up chopsticks one at a time and eat when they have both chopsticks. When finished, they put down both chopsticks and resume thinking.
**Problem Description**
- Setup: Five philosophers, a circular table, and five chopsticks.
- Action: Philosophers alternate between thinking and attempting to pick up two adjacent chopsticks to eat.
- Constraints : A philosopher cannot pick up a chopstick already held by a neighboring philosopher.
- Goal: Allocate resources (chopsticks) among processes (philosophers) to avoid deadlock and starvation.
**Solutions :**
**1. Semaphore Solution**: Each chopstick is represented by a semaphore initialized to 1. A philosopher tries to acquire both required chopsticks and releases them after eating. This approach prevents two neighboring philosophers from eating simultaneously but can lead to deadlock if all philosophers attempt to eat at once.
**2. Deadlock Prevention**: Strategies to prevent deadlock include:
- Limiting the number of philosophers allowed to pick up chopsticks simultaneously.
- Requiring philosophers to pick up both chopsticks at once to avoid one philosopher holding one chopstick indefinitely.
- Using asymmetric strategies where philosophers pick up chopsticks in a specific order based on their position at the table.
**Practical Considerations**
- Starvation: Even with deadlock-free solutions, ensuring fairness to prevent starvation (where a philosopher might never get to eat) remains a challenge.
- Concurrency Control: The dining-philosophers problem serves as a model for managing shared resources among multiple processes or threads, demonstrating the complexities of synchronization and resource allocation.
**Summary**
The dining-philosophers problem exemplifies concurrency challenges in resource allocation and synchronization. Solutions involve using semaphores or other synchronization mechanisms to coordinate access to shared resources while avoiding deadlock and striving to minimize starvation among processes or threads.

1,904,281 | Dancing Ghosts Exploring Static Electricity with Tissue Paper | Learn about static electricity with this fun experiment that makes tissue paper ghosts dance. This blog post explains the science behind static electricity and provides detailed steps for conducting this experiment with kids, either one-on-one or in a classroom setting. | 0 | 2024-06-28T13:50:13 | https://www.rics-notebook.com/blog/Kids/ScienceExperiments/DancingGhost | staticelectricity, dancingghosts, scienceexperiments, kidsscience | # 👻 Dancing Ghosts: Exploring Static Electricity with Tissue Paper 👻
Making tissue paper ghosts dance with static electricity is a fun and simple science experiment that introduces kids to the concepts of static electricity and electrostatic forces. This engaging activity is perfect for sparking curiosity and excitement about physics.
## 🔬 The Science Behind Dancing Ghosts 🔬
Static electricity is the result of an imbalance between positive and negative charges in objects. When certain materials are rubbed together, electrons are transferred from one material to the other, creating static electricity. The charged object can then attract or repel other objects with opposite or similar charges.
### 🌟 Key Concepts:
- **Static Electricity**: The buildup of electric charge on the surface of objects.
- **Electrons**: Negatively charged particles that can move from one object to another.
- **Attraction and Repulsion**: Objects with opposite charges attract each other, while objects with similar charges repel each other.
## 🧪 Materials Needed 🧪
- Tissue paper
- Scissors
- A balloon
- A wool cloth or your hair
## 📋 Detailed Steps to Create Dancing Ghosts 📋
1. **Cut Out Ghost Shapes**:
- Use the scissors to cut small ghost shapes out of the tissue paper. Make sure they are lightweight and have enough surface area to respond to static electricity.
2. **Inflate the Balloon**:
- Blow up the balloon and tie it off. This will be used to generate static electricity.
3. **Generate Static Electricity**:
- Rub the balloon vigorously on the wool cloth or on your hair for about 30 seconds. This will transfer electrons to the balloon, creating static electricity.
4. **Make the Ghosts Dance**:
- Hold the charged balloon close to the tissue paper ghosts. The ghosts will be attracted to the balloon and may even lift off the table and dance in the air.
## 🎓 Teaching Kids About Static Electricity 🎓
### One-on-One Lesson:
1. **Introduction**: Explain the basic concepts of static electricity and how rubbing certain materials together can create a static charge.
2. **Hands-On Activity**: Let the child help cut out the ghost shapes and generate the static charge on the balloon. Guide them through the steps, ensuring they understand each part of the process.
3. **Discussion**: Ask questions to encourage thinking, such as "Why do you think the ghosts are attracted to the balloon?" or "What happens if you rub the balloon on a different material?"
### Classroom Activity:
1. **Group Discussion**: Start with a brief explanation of static electricity and electrostatic forces. Show a video or perform a small-scale demonstration to capture interest.
2. **Group Experiment**: Divide the class into small groups. Provide each group with the necessary materials to create their dancing ghosts.
3. **Interactive Exploration**: Allow the groups to perform the experiment and observe the effects of static electricity. Encourage them to note how different materials affect the static charge.
4. **Sharing Observations**: Have each group present their findings and discuss any variations in their results. Talk about the science behind what they observed.
## 🏆 Best Practices for Performing the Experiment 🏆
### One-on-One:
- **Engagement**: Keep the child engaged by allowing them to handle the materials and generate the static charge. Encourage them to ask questions and make predictions.
- **Safety**: Ensure the child understands not to rub the balloon too hard on their hair to avoid static shocks. Supervise closely and provide guidance as needed.
### Classroom Setting:
- **Preparation**: Prepare all materials in advance and ensure each group has a designated area to work. Lay down protective coverings to manage any mess.
- **Supervision**: Monitor the groups to ensure they handle the materials safely and follow instructions.
- **Clean-Up**: Have a plan for clean-up, as the tissue paper can create small bits of debris. Provide wipes or cloths for quick clean-ups and designate a disposal area for the used materials.
## 🌟 Conclusion 🌟
Exploring static electricity with dancing tissue paper ghosts is a fantastic way to introduce kids to the concepts of static electricity and electrostatic forces. Whether you're working one-on-one or with a group, this experiment is sure to captivate and educate. It's a great opportunity to spark curiosity and excitement about physics while providing a memorable hands-on learning experience.

1,904,280 | Troubleshoot Roadrunner Email After Installing iOS Update 2024 | After updating your iPhone to the latest iOS version in 2024, you might encounter issues with your... | 0 | 2024-06-28T13:49:35 | https://dev.to/raikwar_nikhil_99cb8c5ac5/troubleshoot-roadrunner-email-after-installing-ios-update-2024-hcc |
After updating your iPhone to the latest iOS version in 2024, you might encounter issues with your Roadrunner email. This can be frustrating, especially if you rely on your email for communication. Fortunately, most problems can be resolved with a few troubleshooting steps. This guide will help you identify and fix common Roadrunner email issues that occur after an iOS update.
Verifying Email Account Settings
One of the first steps to [troubleshoot Roadrunner email ](https://roadrunnermailsupport.com/troubleshoot-roadrunner-email-after-installing-ios-update/)issues after an iOS update is to verify your email account settings. Updates can sometimes reset or alter settings, leading to connectivity problems. To ensure your settings are correct, open the Settings app on your iPhone, navigate to Mail, and then to Accounts. Select your Roadrunner account and review the incoming and outgoing mail server settings. The incoming mail server should be set to mail.twc.com, with the appropriate port and SSL settings. The outgoing mail server should also be set to mail.twc.com. Ensure that your username and password are entered correctly for both servers.
Checking Internet Connection
A stable internet connection is crucial for accessing email. Sometimes, an iOS update might interfere with network settings, leading to connectivity issues. Verify that your device is connected to the internet by opening a web browser and trying to visit a few websites. If the internet is not working, try toggling Wi-Fi off and on, switching between Wi-Fi and cellular data, or restarting your router. If the problem persists, reset your network settings by going to Settings, then General, followed by Reset, and selecting Reset Network Settings. Note that this will remove all saved Wi-Fi networks and passwords, so you will need to reconnect to your networks afterward.
Restarting the Device
Restarting your iPhone can resolve many minor glitches that occur after an iOS update. To restart your device, press and hold the power button along with either volume button until the power off slider appears. Slide to power off, wait a few seconds, and then press the power button again to turn the device back on. Once restarted, check if your Roadrunner email is functioning properly.
Removing and Re-adding the Email Account
If the issue persists, consider removing and re-adding your Roadrunner email account. This process can refresh the account settings and resolve any conflicts caused by the iOS update. To remove the account, open the Settings app, go to Mail, then Accounts, select your Roadrunner email account, and tap Delete Account. Confirm the deletion and then re-add the account by selecting Add Account, choosing Other, and entering your Roadrunner email credentials along with the correct server settings.
Updating Email App and iOS
Ensure that both your Mail app and iOS are up to date. App and system updates often include bug fixes and improvements that can resolve compatibility issues.

1,904,278 | Building a Secure OTP-based Login System in Next.js | In today's digital age, ensuring the security of user authentication is paramount. One effective... | 0 | 2024-06-28T13:48:30 | https://dev.to/abdur_rakibrony_97cea0e9/building-a-secure-otp-based-login-system-in-nextjs-gb0 | nextjs, react, authjs, otp | In today's digital age, ensuring the security of user authentication is paramount. One effective method is using One-Time Passwords (OTPs) for login. In this post, we'll walk through how to implement an OTP-based login system using Next.js, with both email and phone number options.
**Why Use OTP?**
OTPs add an extra layer of security by requiring a temporary code sent to the user's email or phone number. This method reduces the risk of unauthorized access, as the code is valid for a short period.
**Setting Up the Frontend**
We start by creating a login component that captures the user's email or phone number and handles OTP sending and verification.
```
//login component
"use client";
import { useState, useEffect } from "react";
import { Input } from "@/components/ui/input";
import { Lock, Mail, Phone } from "lucide-react";
import { Button } from "@/components/ui/button";
import {
InputOTP,
InputOTPGroup,
InputOTPSlot,
} from "@/components/ui/input-otp";
import { SendOTP } from "@/utils/SendOTP";
import { useRouter } from "next/navigation";
import { signIn } from "next-auth/react";
const Login = () => {
const [contact, setContact] = useState("");
const [otp, setOtp] = useState(false);
const [otpCode, setOtpCode] = useState("");
const [receivedOtpCode, setReceivedOtpCode] = useState("");
const [timeLeft, setTimeLeft] = useState(60);
const [timerRunning, setTimerRunning] = useState(false);
const [resendClicked, setResendClicked] = useState(false);
const [hasPassword, setHasPassword] = useState(false);
const [password, setPassword] = useState("");
const [isIncorrectOTP, setIsIncorrectOTP] = useState(false);
const router = useRouter();
const handleSendOtp = async () => {
setOtp(true);
startTimer();
setResendClicked(true);
const data = await SendOTP(contact);
if (data?.hasPassword) {
setHasPassword(data?.hasPassword);
}
if (data?.otp) {
setReceivedOtpCode(data?.otp);
}
};
const handleLogin = async () => {
if (otpCode === receivedOtpCode) {
await signIn("credentials", {
redirect: false,
email: isNaN(contact) ? contact : contact + "@gmail.com",
});
router.push("/");
} else {
setIsIncorrectOTP(true);
}
};
const startTimer = () => {
setTimeLeft(60);
setTimerRunning(true);
};
const resendOTP = () => {
setTimerRunning(false);
startTimer();
setResendClicked(true);
handleSendOtp();
};
useEffect(() => {
let timer;
if (timerRunning) {
timer = setTimeout(() => {
if (timeLeft > 0) {
setTimeLeft((prevTime) => prevTime - 1);
} else {
setTimerRunning(false);
}
}, 1000);
}
return () => clearTimeout(timer);
}, [timeLeft, timerRunning]);
useEffect(() => {
if (contact === "" || contact === null) {
setOtp(false);
setOtpCode("");
setTimeLeft(60);
setTimerRunning(false);
setResendClicked(false);
}
}, [contact]);
return (
<div>
<div className="relative w-full max-w-sm">
{contact === "" || isNaN(contact) ? (
<Mail

)}
<Input

placeholder="Email or phone"
onChange={(e) => setContact(e.target.value)}
disabled={contact && otp}
className="pl-10"
/>
</div>
{hasPassword ? (
<div className="relative w-full max-w-sm mt-4">

)}
{contact && otp && (

</InputOTPGroup>
</InputOTP>
<div>
{resendClicked && timeLeft > 0 ? (
<p className="text-sm">
Resend OTP available in{" "}
<span className="text-blue-500">
{timeLeft > 0 ? `${timeLeft}` : ""}
</span>
</p>
) : (
<Button
variant="link"
onClick={resendOTP}
className="text-blue-500"
>
Resend OTP
</Button>
)}
</div>
</div>
)}
</div>
)}
{receivedOtpCode ? (
<Button
onClick={handleLogin}
className="w-full mt-4 bg-green-500 hover:bg-green-400"
>
Login
</Button>
) : (
<Button
onClick={handleSendOtp}
className="w-full mt-4 bg-green-500 hover:bg-green-400"
>
Next
</Button>
)}
{isIncorrectOTP && (
<p className="text-red-500 text-sm text-center mt-2">
Incorrect OTP. Please try again.
</p>
)}
</div>
);
};
export default Login;
```
This component manages the user interaction for entering their contact information, sending the OTP, and handling the login process. It includes state management for various aspects such as OTP verification, countdown timer, and error handling.
**Backend API for OTP Generation and Sending**
Next, we'll set up the backend to handle OTP generation and sending. The OTP can be sent via email or SMS based on the user's contact information.
```
//OTP Generation and Sending
import { sendVerificationSMS } from "@/lib/sendSMS";
import User from "@/models/user";
import { NextResponse } from "next/server";
import { connectToDB } from "@/lib/db";
import nodemailer from "nodemailer";
const generateOTP = () => {
const digits = "0123456789";
let OTP = "";
for (let i = 0; i < 4; i++) {
OTP += digits[Math.floor(Math.random() * 10)];
}
return OTP;
};
const sendVerificationEmail = async (contact, otp) => {
try {
let transporter = nodemailer.createTransport({
service: "gmail",
auth: {
user: "your-email@gmail.com",
pass: "your-email-password",
},
});
let info = await transporter.sendMail({
from: `"Your Company" <your-email@gmail.com>`,
to: contact,
subject: "Verification Code",
text: `Your verification code is: ${otp}`,
});
return info.messageId;
} catch (error) {
console.error("Error sending email:", error);
throw new Error("Error sending verification email");
}
};
export async function POST(req, res) {
try {
await connectToDB();
const otp = generateOTP();
const { contact } = await req.json();
const existingUser = await User.findOne({
email: isNaN(contact) ? contact : contact + "@gmail.com",
});
if (isNaN(contact)) {
await sendVerificationEmail(contact, otp);
return NextResponse.json({
message: "Verification code has been sent to your email",
otp,
});
} else {
await sendVerificationSMS(contact, otp);
return NextResponse.json({
message: "Verification code has been sent",
otp,
});
}
} catch (error) {
console.error(error);
return NextResponse.error(
"An error occurred while processing the request."
);
}
}
```
This backend code handles OTP generation and sends it either via email or SMS depending on the user's input. The generateOTP function creates a random 4-digit OTP, and the sendVerificationEmail and sendVerificationSMS functions send the OTP to the user.
**Conclusion**
Implementing an OTP-based login system enhances the security of your application by adding an additional verification step. This system ensures that only users with access to the provided email or phone number can log in, protecting against unauthorized access.
Feel free to modify and expand upon this basic implementation to suit your specific requirements. Happy coding!

1,904,290 | ReactJS vs. React Native: A Beginner's Guide | Introduction: ReactJS and React Native are two powerful technologies from Facebook that have... | 0 | 2024-06-28T13:48:00 | https://dev.to/lukman_saidmodibbo_be550/reactjs-vs-react-native-a-beginners-guide-1kme | webdev, javascript, beginners | Introduction:
ReactJS and React Native are two powerful technologies from Facebook that have revolutionized the way we build web and mobile applications. While they share a common name and some similar principles, they serve different purposes. In this article, we'll compare ReactJS and React Native, highlighting their key differences and unique features. We'll also touch upon my expectations with React during the HNG Internship program.
ReactJS vs. React Native:
1. Purpose and Usage:
ReactJS: ReactJS, often referred to simply as React, is a JavaScript library used for building user interfaces, primarily for web applications. It allows developers to create reusable UI components and manage the state of their web applications efficiently.
React Native: React Native is a framework that enables developers to build mobile applications using JavaScript and React. It allows for the development of native mobile apps for both iOS and Android platforms using a single codebase.
2. Platform Differences:
ReactJS: ReactJS is used exclusively for web development. It works in the browser and interacts with the DOM (Document Object Model) to render web pages.
React Native: React Native is used for mobile app development. It compiles to native code, allowing the apps to perform like native apps on both iOS and Android devices.
3. Development Environment:
ReactJS: For ReactJS development, you primarily need a code editor like VS Code and a web browser for testing. You write components using JSX (JavaScript XML) which makes the code more readable and maintainable.
React Native: React Native development requires additional setup, including an emulator or a physical mobile device for testing. You'll also need tools like Expo or React Native CLI. React Native components are written in JSX but render to native components.
4. Components:
ReactJS: Components in ReactJS are HTML-like elements that render to the DOM. They can be functional or class-based components.
React Native: React Native components are not HTML elements. Instead, they map to native components like <View>, <Text>, and <Image> which are used to build the UI for mobile apps.
5. Styling:
ReactJS: In ReactJS, you typically use CSS or CSS-in-JS libraries like styled-components for styling.
React Native: In React Native, styling is done using JavaScript objects that resemble CSS but have different properties. You use the StyleSheet API provided by React Native.
My Expectations with React at HNG:
As a beginner, I am thrilled to use React in the HNG Internship program. I look forward to building complex and dynamic web applications, honing my skills in component-based architecture, and learning best practices from experienced developers. The hands-on experience with React will prepare me for real-world projects and enhance my understanding of modern web development.
Conclusion:
ReactJS and React Native are both fantastic technologies for building modern applications, but they serve different purposes. ReactJS is ideal for web development, while React Native is perfect for mobile app development. By understanding their differences and unique features, developers can choose the right tool for their specific project needs.

1,904,277 | The Benefits of Performance-Based Contracting for Government Projects | Discover how performance-based contracting can revolutionize government projects, enhancing efficiency, accountability, and innovation. | 0 | 2024-06-28T13:47:26 | https://www.govcon.me/blog/the_benefits_of_performance_based_contracting_for_government_projects | government, contracting, innovation | # The Benefits of Performance-Based Contracting for Government Projects
In today's rapidly changing world, government projects must adapt to deliver high-quality results efficiently and cost-effectively. Performance-Based Contracting (PBC) is emerging as a game-changer, offering a multitude of benefits that can significantly enhance public sector project management. Let's delve into why PBC could be the catalyst for a new era of government efficiency and innovation.
## The Evolution: From Traditional to Performance-Based Contracting
Traditional contracting methods often focus on specific inputs and processes, rather than outcomes. This approach can lead to:
- **Inflexibility**: Contractors stick to the letter of the contract, even when better solutions emerge.
- **Inefficiency**: Time and resources are wasted on micromanagement and detailed oversight.
- **Limited Innovation**: Contractors are not incentivized to innovate as their compensation isn't tied to results.
Performance-Based Contracting, in contrast, shifts the focus onto outcomes and results. Here's why this paradigm shift is transformative:
### Increased Accountability
By linking payment directly to performance, PBC holds contractors accountable for delivering specific results. Key performance indicators (KPIs) and Service Level Agreements (SLAs) are established, ensuring that contractors are only compensated when pre-defined objectives are met. This minimizes the risk of cost overruns and spurs consistent delivery of high-quality services.
### Enhanced Efficiency
With PBC, the emphasis on outcomes rather than processes allows contractors greater flexibility to use their expertise. Contractor innovation is incentivized and micromanagement is reduced, leading to more streamlined operations and faster project completions. Efficiency gains are a direct result of allowing skilled professionals to do what they do best without unnecessary bureaucratic hurdles.
### Promoting Innovation
PBC fosters an environment where innovation is not only encouraged but rewarded. Contractors are motivated to develop and implement creative solutions to meet performance targets. This dynamic environment can lead to cutting-edge advancements and methodologies, driving the sector forward as a whole.
### Risk Management
One of the standout benefits of PBC is its risk mitigation. By defining clear performance metrics, governments can transfer certain performance risks to contractors. This alignment of interests ensures that contractors are equally invested in the project's success, creating a win-win scenario for all parties involved.
### Cost-Effectiveness
While there may be initial setup costs associated with developing comprehensive PBC frameworks, the long-term financial benefits are substantial. Cost savings stem from reduced waste, efficient resource utilization, and the elimination of time-consuming oversight processes. Ultimately, taxpayers benefit from the judicious use of public funds.
### Examples in Action
Several governments around the world have already harnessed the power of PBC with impressive results:
1. **United States Federal Government**: The Federal Aviation Administration (FAA) utilized PBC for its telecommunications infrastructure, resulting in faster deployment and cost savings.
2. **United Kingdom**: The Department for Work and Pensions adopted PBC for employment services, leading to improved job placement rates and better outcomes for job seekers.
3. **Australia**: The Department of Defence's PBC initiatives have streamlined procurement processes and enhanced capability delivery.
## Implementing Performance-Based Contracting
Ready to embrace PBC for your government projects? Here's a step-by-step guide to get started:
### 1. Define Clear Objectives
Outline specific, measurable, achievable, relevant, and time-bound (SMART) objectives. This will form the basis of your KPIs and SLAs.
### 2. Develop Performance Metrics
Work with stakeholders to develop clear performance metrics. These should be directly linked to payment structures, ensuring that incentives are aligned with desired outcomes.
### 3. Select the Right Contractors
Choose contractors with a proven track record of innovation and efficiency. Their expertise will be crucial in meeting performance targets.
### 4. Foster Collaboration
Maintain open lines of communication with contractors. Collaboration is key to overcoming challenges and achieving successful outcomes.
### 5. Monitor and Evaluate
Regularly assess performance against the established metrics. Provide feedback and make adjustments as necessary to stay on track.
## The Future of Public Sector Projects
Performance-Based Contracting is not just a trend; it's a blueprint for the future of public sector projects. By embracing PBC, governments can unlock new levels of efficiency, accountability, and innovation, ultimately delivering better services to citizens. It's time to reimagine the possibilities and set a new standard for government project management.

1,904,271 | Ceph 의 이해(1) | 개요 요번에 ceph 장비를 모니터링해야 된다는 말이 있어서... Ceph에 대해 좀 리서치 해봤다. 우린 사실 Ceph 관련된 모니터링 요소만 알면 되는데,... | 0 | 2024-06-28T13:45:05 | https://dev.to/hj_lee/ceph-yi-ihae1-3ac3 | ceph, storage, cloud | ## 개요
요번에 ceph 장비를 모니터링해야 된다는 말이 있어서... Ceph에 대해 좀 리서치 해봤다.
우린 사실 Ceph 관련된 모니터링 요소만 알면 되는데, 메트릭을 분석하려면 기본지식이 좀 있어야 하니 어쩔 수 없이[?] 메트릭에 나오는 단어들 위주로 분석을 한번 해봤다.
- 여담인데, 요즘은 참 좋은 시대긴 하다. GPT로 일단 간단하게 단어 스크리닝하고, 애매한 부분이나 이해가 안 되는 부분등은 도큐먼트로 채워 봤는데, GPT가 틀린 말을 거의 안 했음.
- 그래서 쪼금 틀린 부분이 있을 수 있고...어느정도 내 편의대로 생각한 부분도 있을것이다...대부분 문서로 확인은 했지만...
## Ceph?
[Ceph Intro](https://docs.ceph.com/en/reef/start/intro/)
- Ceph는 redhat이 만든 클라우드 플랫폼에 적합한 스토리지...서비스 같은 거?
- Object storage, block device, Filesystem 모두 지원!(대단하다)
- Cluster로 구성 가능하고, 대규모 파일 관리에 매우 좋아 보인다.
- Ceph는 매우 당연하게도 데이터 분산, 복제, 무결성 등을 지원하고, 데이터 분산 같은 것들은 CRUSH 라는 해시 알고리즘을 통해 분배하고 관리한다. CRUSH에 관해서는 자세히 찾아보진 않았지만, 상당히 자주 언급됨.
## OSD, object
1. object는 '논리적 최소 단위'로서, 일반적으로 생각하는 Object Storage의 객체와는 조금 동떨어진 것으로 보인다.(ceph에서는 RADOS object라고 함)
일반적인 Object storage와는 비슷한 점이 있는데 object는 filesystem처럼 특정 디렉토리 구조에 얽매이는 것이 아니라 'flat한 namespace'에 저장된다고 함. 계층이 존재하지 않는다.
2. OSD(object storage device)는 '물리 장비의 논리적 단위'로서 쉽게 말하면 disk 정도에 매핑될 것 같다. object는 OSD에 저장되고, OSD는 실제 디스크에 파일 세그먼트를 기록하는 형식이 되겠다.
## Placement Group
PG(Placement group)은 '논리적 단위'인데, 대부분의 분산, 복제 작업이 이 단위를 기준으로 이루어진다.
'논리적 관점'에서는 object < PG.
'물리적 관점'에서는 object < OSD
가 된다.<br>
이 PG의 개념을 도큐먼트에서는 'layer of indirection'(간접 계층) 라고 부르는데, PG라는 간접 계층을 둠으로서 object와 OSD간의 결합도를 줄이고 유연성을 증대시키는 효과를 가져온다.
대충 살펴봤을때도 PG는 대부분의 데이터 무결성에 반드시 등장하는 존재이며, 해당 존재를 통해 Client가 접근해야 할 OSD를 정확하게 계산할 수 있다고 한다. 당연히 CRUSH 알고리즘을 통해서 ㅋㅋ
### Replication
PG의 Replication은 나름대로 단순하다면 단순한 구조로, Primary, Secondary(+@)로 이루어진다.
Primary에 먼저 데이터를 쓰고, Primary라 secondary에 분배하는 형식으로 무난한 구조라고 볼 수 있다.
### Sharding
PG의 Sharding은 erasure coding이라고 부르는데, erasure encoding function을 통해 데이터를 분해하고 추가 패리티를 붙여 OSD에 따로 저장한다.
마찬가지로 데이터 통합 시에는 decoding function을 이용하게 됨. 단순하다면 단순한 구조기도 하고...예시의 그림은 shard 하나가 실패(too slow)하는 것을 전제로 했는데, 이 상황에서는 데이터를 못 읽어오는 hang상태겠지만 실제로는 복제본이 있으니까 괜찮지 않을까 싶긴 하다.
## Pool
Pool 또한 '논리 단위'로, Cluster보다는 작은 개념이지만 일종의 파티션 역할을 하는 단위이다.
살펴봤을때 Openstack의 project라던가, k8s의 namespace와 같은 분리 파티션 역할을 하는 것 같다.
<br>
Pool을 분리하면 해당 요소들이 달라지게 된다.
- Ownership/Access to Objects
- Number of Placement Groups
- CRUSH Rule
단순히 논리적 분리 뿐만 아니라 Crush rule이나 PG 조절, 설정 분리와 같은 것도 있기 때문에 분리가 잘 된다면 storage의 사용 용도나 장비의 여건에 따라 아예 다른 장비처럼 운용이 가능하다는 게 가장 큰 메리트.
## 전체 관계도
단순 도식화긴 하지만, 앞의 설명을 통해 어느정도 이해가 가능할 것이다.
<br>
## 결론
- 익숙한 개념들도 있고, 생소한 개념도 있고.
- 현대의 데이터 분산 시스템을 차용함과 동시에, object 단위를 기반으로 대규모 클러스터 시스템과 함께 쓸 수 있게 고안한 것 같다. 일반적인 Cloud-k8s 시스템에서 스토리지를 따로 찾아서 설정하고 볼륨 지정하고 이게 좀 귀찮았는데 ceph를 잘 이용하면 하나의 엔드포인트만 봐도 되니 꽤 좋아 보임.
- 다음은 PG를 중심으로 어떻게 데이터를 관리하고 분산하고 무결성을 확보하는지 알아본다.

**1. Requirement Gathering and Planning**
Understanding the requirements was crucial. I had detailed meetings with stakeholders to grasp their needs, which included multi-currency support, real-time exchange rate updates, user authentication, data security, and scalability.
**2. Choosing the Tech Stack**
Based on the requirements, I chose Node.js for its asynchronous capabilities and scalability, MongoDB for its flexibility with unstructured data, and Redis for caching exchange rates to ensure fast access.
**3. Setting Up the Project**
I started by setting up the project structure, integrating Express.js for handling routes, and connecting to MongoDB to establish a solid foundation.
**4. Implementing Multi-Currency Support**
To handle multiple currencies, I integrated a reliable third-party API for real-time exchange rates.
**5. Ensuring Data Integrity**
Concurrency issues can lead to data corruption, so I used transactions in MongoDB to ensure atomicity and data consistency.
**6. Optimizing Performance with Caching**
Fetching exchange rates frequently can be costly and slow, so I implemented caching using Redis to improve performance.

Government contracting can seem like a daunting labyrinth, but for businesses looking to expand and secure steady revenue, it's an avenue worth navigating. In this blog post, we'll take you through the essential steps and tips to get started in government contracting, demystifying the process and setting you on the path to success.
## Understanding the Landscape
### What is Government Contracting?
Government contracting involves a private company entering into a legal agreement to provide goods or services to a government entity. This can range from local and state governments to federal agencies. The opportunities are vast and varied, making it an appealing option for many businesses.
### Why Should You Consider Government Contracts?
1. **Stable Revenue Stream**: Government contracts can provide a steady stream of income over extended periods.
2. **High Payment Security**: Since the government is the client, the risk of non-payment is minimal.
3. **Expansion Opportunities**: Successfully executing a government contract can enhance your business's reputation and open doors to new opportunities.
## Getting Started
### 1. **Research & Identify Opportunities**
Begin by identifying which government agencies need your products or services. Websites like [SAM.gov](https://sam.gov) (System for Award Management) list available contracts from different federal agencies. You can also look at specific agency websites for opportunities.
### 2. **Register Your Business**
Before you can bid on government contracts, your business must be registered. Here�s how:
- **Obtain a DUNS Number**: This is a unique nine-digit identifier for businesses.
- **Register with SAM**: The System for Award Management (SAM) is the primary database for vendors doing business with the federal government. Registration is free.
### 3. **Certify Your Business**
Different certifications can give your business a competitive edge:
- **Small Business Certification**: The Small Business Administration (SBA) offers various programs that benefit small businesses.
- **8(a) Business Development Program**: Assists small, disadvantaged businesses.
- **Women-Owned Small Business (WOSB) Certification**: Helps women entrepreneurs.
- **Veteran-Owned Small Business (VOSB) Certification**: Supports veteran business owners.
### 4. **Understand the Bidding Process**
Once registered, it's time to bid for contracts. Government contracts often follow a special bidding process:
- **Request for Proposal (RFP)**: A detailed list of what the agency needs.
- **Request for Quotation (RFQ)**: Typically used for services or products that are known and understood.
- **Invitation for Bid (IFB)**: More formal, often used for complex projects.
### 5. **Prepare a Competitive Bid**
Creating a winning proposal involves:
- **Understanding Requirements**: Make sure your proposal is tailored to the specific needs of the RFP.
- **Competitive Pricing**: Ensure your pricing is competitive but also realistic, factoring in all costs to deliver the service or product.
- **Quality Content**: Present a clear, concise, and compelling narrative that highlights your business strengths and experience.
### 6. **Building Relationships**
Like any industry, networking can play a crucial role. Attend industry days, procurement conferences, and meet government procurement officers to better understand their needs and processes.
## Tips for Success
### **Stay Compliant**
Government contracts come with stringent compliance requirements. Familiarize yourself with the [Federal Acquisition Regulation (FAR)](https://www.acquisition.gov/far/) to ensure you�re in compliance.
### **Focus on Quality**
Always prioritize the quality of your product or service. Government entities value reliability and high standards.
### **Be Patient**
Winning a government contract can be a lengthy process. Stay persistent and patient, continually refining your bids and understanding of the process.
## Final Thoughts
Government contracting may seem complex at first, but with diligent research, strategic planning, and a focus on compliance, your business can unlock a steady and lucrative revenue stream. So, dive in, explore opportunities, and take the steps outlined above to get started on your government contracting journey. The rewards are well worth the effort! | quantumcybersolution |
1,902,298 | Controlling AWS Lambda Costs | Managing your Amazon Web Services (AWS) costs can be challenging. AWS provides tools to limit usage... | 27,937 | 2024-06-28T13:36:26 | https://dev.to/kodsama/controlling-aws-lambda-costs-2kn8 | aws, cost, lambda, devops | Managing your Amazon Web Services (AWS) costs can be challenging. AWS provides tools to limit usage and notify you when costs rise unexpectedly. This guide focuses on scalable AWS services like [AWS Lambda](https://aws.amazon.com/lambda/) to help you keep costs under control.
Manually tearing down services when your budget is high is cumbersome. Instead, spend time setting up automated limits to prevent overspending.
## Steps to Control Costs
1. [Set Up Billing Alarms](#budget)
2. [Limit Lambda Concurrency](#concurrency)
- [Reduce Global Service Quotas](#quota)
- [Set Concurrency Limits for Individual Lambda Functions](#limit)
- [Set Rate Limits on API Gateway](#api)
- [Use AWS WAF to Avoid HTTP Flooding](#waf)
3. [Using a Killer Lambda](#killer)
4. [Closing Thoughts](#closing)
---
## Setting Up Billing Alarms <a name="budget"></a>
The first step is to set up budget alerts for your AWS costs. This way, you’ll get notified if your monthly AWS bill is estimated to cross a set threshold.
1. **Create a Budget**:
- Go to the AWS Management Console.
- Navigate to the AWS Budgets dashboard.
- Click on "Create a budget."
- Follow the steps to set your budget amount.
2. **Configure Alerts**:
- Set up alert notifications for when your budget threshold is reached. You can receive alerts via email or SNS (Simple Notification Service).
- To use SNS, create an SNS topic if you don't have one, and add subscribers (e.g., your email address).
With these alerts, you’ll know when you’re approaching your budget and can take action.
---
## Limiting Lambda Concurrency <a name="concurrency"></a>
Balancing scalability and cost is crucial. Limit Lambda invocations to prevent unexpectedly large bills.
### Reduce Global AWS Service Quotas for Lambda <a name="quota"></a>
Lower the total concurrency of all Lambda invocations (default is 1000):
1. Go to the AWS Management Console.
2. Search for "Service Quotas."
3. Filter for "Lambda."
4. Click on "Concurrent executions."
5. Click the "Request quota increase" button.
6. Fill in the new limit and submit the request.
### Set Concurrency Limits for Individual Lambda Functions <a name="limit"></a>
Limit concurrent invocations of specific Lambda functions:
1. Navigate to the desired Lambda function in the AWS Console.
2. Go to Configuration > Concurrency.
3. Click "Edit" in the Concurrency section.
4. Select "Reserve concurrency" and set the limit.
5. Click "Save."
### Set Rate Limits on API Gateway <a name="api"></a>
Control the number of requests sent to your backend:
1. Go to the AWS Management Console.
2. Search for "API Gateway."
3. Select your API.
4. Go to "Stages" and select the stage (e.g., `prod`, `dev`).
5. Scroll to the "Throttle" section in the "Stage Editor" tab.
6. Set the Rate Limit and Burst Limit.
7. Click "Save Changes."
### Use AWS WAF to Avoid HTTP Flooding <a name="waf"></a>
Protect against DDoS attacks by setting rate limits and blocking excessive requests:
1. Go to the AWS Management Console.
2. Search for "WAF."
3. Click on "Create web ACL."
4. Add a rate-based rule with your desired rate limit.
5. Set the action to "Block" when the rate limit is exceeded.
6. Select the resources you want to protect.
7. Click "Create web ACL."
---
## Using a Killer Lambda <a name="killer"></a>
To prevent AWS API Gateway and AWS Lambda from being invoked when a specific budget is reached, we can combine multiple AWS tools. For the sake of readability, I moved this part to a new article: [AWS cost control last resort, the killer lambda](https://dev.to/kodsama/aws-cost-control-last-resort-the-killer-lambda-5mk).
---
## Closing Thoughts <a name="closing"></a>
By following these steps, you can ensure that your AWS API Gateway and Lambda functions are managed effectively, preventing further costs and limiting possible cost overruns. This approach ensures your services are controlled and automatically restored at the beginning of the next period, keeping costs in check.
Managing AWS costs can be tough, but with the right setup, you can avoid unexpected expenses. Start with billing alarms and budgets, then use concurrency limits and API Gateway rate limits to control usage. AWS WAF can also protect against unexpected spikes.
Implementing these steps takes effort but will save you from manual intervention and unexpected costs in the long run. Focus on development, knowing your AWS costs are under control.
Address cost explosions in the development stage, but at least you can sleep peacefully until then. 😴 | kodsama |
1,904,130 | The Ultimate Bootstrap v/ Tailwind CSS Comparison | The world of web development is constantly evolving and choosing the right CSS framework can... | 0 | 2024-06-28T13:35:00 | https://dev.to/dixonsilveroff/the-ultimate-bootstrap-v-tailwind-css-comparison-4j7h | webdev, css, tailwindcss, bootstrap | The world of web development is constantly evolving and choosing the right CSS framework can significantly impact the success rate of the project you're building. Bootstrap and Tailwind CSS are two of the most popular frameworks available today. While both aim to streamline the styling process, they take fundamentally different approaches. In this article, I’ll explore the key differences between Bootstrap and Tailwind CSS and rate them on my personal scale to help you make informed decisions for your future projects.
Let's dive in, right away!
---
### Overview
#### Bootstrap: Component-Based Framework
Bootstrap, developed by Twitter, is one of the oldest and most widely used CSS frameworks. It offers a rich set of pre-styled components and a responsive grid system that allows developers to quickly build consistent and aesthetically pleasing websites.
#### Tailwind CSS: Utility-First Framework
Tailwind CSS (referred to as 'Tailwind' now henceforth), on the other hand, is a newer framework that focuses on a utility-first approach. Instead of providing pre-designed components, Tailwind offers low-level utility classes that can be combined to create custom designs. This approach provides greater flexibility and control over the final appearance of the application. Utilities are simple HTML classes typically scoped to a single CSS property which when added to a HTML Element, styles it accordingly, eg.
```
**CSS**
.block {
color: white;
background-color: teal;
margin: 10px;
}
.p-1 {
padding: 1rem;
}
**HTML**
<div class="block p-1"></div>
```
### Comparison
1. #### Design Philosophy
As mentioned before, **Bootstrap** provides a component-based approach with pre-styled UI elements, making it easy to build websites quickly. This however, can sometimes lead to a "Bootstrap look" which is common to many websites.
On the other hand, **Tailwind** offers a utility-first approach, giving developers granular control over the styling of their elements. This allows for more unique designs but requires a deeper understanding of CSS principles.
2. #### Beginner Support
**Bootstrap** is easier for beginners to get started with due to pre-designed components and ready-to-use styles.
While, **Tailwind** requires understanding of utility classes and how to combine them to create custom designs, which can be a bit challenging for beginners.
3. #### Responsive Design
**Bootstrap** uses a mobile-first approach with predefined breakpoints.
But **Tailwind CSS** boasts of flexible responsive design with customizable breakpoints.
4. #### Browser Support
**Bootstrap** supports all modern browsers and includes some polyfills for older browsers.
Meanwhile, **Tailwind** supports modern browsers with a focus on newer CSS features.
> A polyfill is a piece of code used to provide modern functionality on older browsers that do not natively support it.
5. #### Performance
**Bootstrap**'s larger CSS file and potentially unused styles can affect performance.
While, **Tailwind** promises better performance with minimized CSS files using tools like PurgeCSS.
6. #### Accessibility (a11y)
**Bootstrap** is built with a11y in mind, including ARIA roles and best practices.
But, **Tailwind** requires manual handling of a11y concerns.
7. #### Development Speed
Use **Bootstrap** if you want to get a decent-looking site up and running faster with pre-styled components.
On the other hand, **Tailwind** is faster for creating unique, custom designs without writing custom CSS.
8. #### Integration w/ Frontend Frameworks
**Bootstrap** can be integrated with various front-end frameworks but might require some little additional adjustments.
On the contrary, **Tailwind** easily integrates with modern JavaScript frameworks like ReactJS, Vue, and Angular.
9. #### Community and Ecosystem
**Bootstrap** boasts of a large community with extensive resources, plugins, and themes, offering sufficient support for it's userbase.
**Tailwind** still has growing community with increasing resources and third-party components.
### Use Cases
#### When to Use Bootstrap
**Bootstrap** is ideal for projects that need to be developed quickly with consistent aesthetics especially when used during a team project. Its pre-styled components are perfect for quick prototyping and MVPs.
#### When to Use Tailwind
**Tailwind** is better suited for projects that require highly customized designs. Its utility-first approach allows for greater flexibility, making it a favorite among developers who want complete control over their styling.
### Conclusion
Both **Bootstrap** and **Tailwind** have their strengths and weaknesses. **Bootstrap**'s component-based approach makes it perfect for rapid development and consistent design, while **Tailwind**'s utility-first philosophy offers unparalleled flexibility and control.
Ultimately, the choice between **Bootstrap** and **Tailwind** depends on your project's specific needs and your personal preferences as a developer. I'd also love to hear the unique thoughts of you devs out there concerning these two wonderful frameworks. Leave them in the comments!

1,904,256 | The interesting regex for Identifying Prime Numbers | Prime numbers are numbers greater than 1 that have no positive divisors other than 1 and... | 0 | 2024-06-28T13:33:34 | https://dev.to/joaoreider/the-interesting-regex-for-identifying-prime-numbers-405h | regex, math |
Prime numbers are numbers greater than 1 that have no positive divisors other than 1 and themselves.
The regex is `^1?$|^(11+?)\1+$`
Let's breaking Down...
First you need to know the meaning of these 3 symbols:
- **^**: _start of the string_
- **$**: _end of the string_
- **|**: _OR operator_
So we have two components in the main regex:
`1?`: The literal “1” and the question mark "?" for match the previous char zero or one times. So if we have zero characters or “1” it will match. Soon we will know the reason for this pattern here.
`(11+?)\1+`: The second pattern. `(11+?)` is a group and matches any string that starts with “11” by one or more “1”s. The “+?” makes it non-greedy, meaning it matches as few characters as possible.
`\1+` capture the same text again with as many characters as possible.
> E.g. So for the number '111111', the pattern '11' is repeated three times. For the number 5 ('11111'), there is no way to split it into repeated sub-patterns.
So the interesting thing is that we found how to evenly divide repeated sub patterns.
In the same number '111111', the pattern '111' is also repeated twice and this is captured by regex.
For prime numbers, the string cannot be divided evenly into repeating sub patterns.
Ah, and first pattern (1?) handles the non-prime cases of 0 and 1.
Thank you for reaching this point. If you need to contact me, here is my email: joaopauloj405@gmail.com

This article will give you a reality check so, be prepared for that. Before reading this article I would like to say "Be honest with yourself".
Note: _This article is solely for people who want to crack placements and want to mold themself to crack placements._
I know what you all are going through - self-doubt, low self-esteem, lack of guidance, lack of confidence, distracted in your life, don't know what to do, and the list goes on and on. Listen to me **stop overthinking** and **start doing what you enjoy**, **what you love to do**, and **what you're passionate about**. Just do it **I don't know who is stopping you** from doing things that you love to do.
Stop thinking about society just do what you want to do and **be the best** in it, let me tell you one thing "_Your time will come when people will say I want to become like him/her and you will be someone's inspiration_" seems like a dream right?
Believe me 1. when you will **raise your bar** 2. when you will **start believing in yourself** 3. when you will **start doing things that create impacts** in society that's the point when **people around you will start believing in you**.
> You shouldn't focus on why you can't do something, which is what most people do. You should focus on why perhaps you can, and be one of the exceptions.
Now let's come back to the topic.
## 1. Stop overwhelming your mind with lots of things. Just focus on one thing that can land you a job.
- Don't get distracted doing multiple things. Focus on one thing that's the formula to secure a job.
- Ask yourself what you want to do. If you're unable to answer and have less time **learn a tech stack that can easily land you a job either** in a startup or any company that's my personal opinion.
## 2. Build Crazy projects.
- Believe me, for off-campus opportunities companies look for students who have built crazy things.
- Your project should be technically challenging which makes you stand out from the crowd. Your project should be config-driven it should offer functionalities like searching, sorting, filtering out things, infinite scrolling, a recommendation system, skeleton loaders, leveraging LLM's power, and so on.
- You can build anything such as web apps, mobile apps, chrome extensions, iOS apps, or cool games as well.
- **Build something** that can be used in day-to-day life and **deploy it**.
- **Share your project on LinkedIn**, Twitter, and Reddit and clearly mention what are the features, what was the most challenging part of the project, what are your inspiration for building this project, and what are the future scopes of the project.
## Polishing Resume (One-pager Resume).
- Share your social media proofs such as LinkedIn, Github, Portfolio Website(not mandatory but as a developer, you should have one), and Leetcode.
- Mention technical skills.
- Showcase your projects and give a brief overview of your projects including the tech stack you've used to build the project. Make sure you provide a GitHub link to the project if possible share the deployed link of your project.
- Use actionable keywords.
- Make it ATS friendly and check whether your resume passes the ATS score or not.
- Companies don't care about fancy resumes the only thing that matters is whether you're able to justify what you've got on that single page or not. Keep it simple and minimal.
- CGPA is not mandatory (if you have a decent CGPA above 7 put it).
- Mention your extra-curricular activities it reflect your personality.
- Share value-added certificates.
## Communication is the key to your entrance
- Many students are good at tech but, they lack in presentation.
- Let me share one real example: What if your sister says I know the recipe for the food but I don't know how to cook it. (No hate to sister)
It's the the same thing - **I know how to build the product but, I'm unable to sell the product**. No matter how many functionalities you provide if you fail to articulate those functionalities no one is going to buy that product.
- Focus on your communication skills. Learn to articulate your thoughts in plain words.
- Listen + Practice => Good Communicator
## Keep applying for jobs
- **Daily apply for 50-100 jobs**. Keep applying insanely.
- Give interviews and learn from the interviews. You can fail 5-10-15 and even more interviews **don't get scared** but, slowly and steadily you will gain confidence and self-esteem which will make you good at handling interview pressure.
- Embrace the failures and learn from them.
- Get the feedback from the interviewer and start working on it.
- Ask for referrals.
- Apply at start-ups. The chances of getting shortlisted will be increased. At the initial stage of your career join any of the start-ups because you will know how things work, you need to be multi-tasking in start-ups, and these things will help you a lot in your later stage.
> Our greatest glory is not in never falling, but in rising every time we fall. (Confucius)
Do you know where the problem exists? Students are mad about FAANGS and as a fresher, they expect _X LPA_. I am not saying you should stop dreaming about high-paying jobs. I am saying to match the expectation with your reality. If you're capable enough crack it. Just be honest with yourself that's it.
Let's not be so quick to judge companies as good or bad. **Getting experience is what really matters**, and that can happen in all sorts of places—from startups to big companies like TCS, Wipro, and Infosys. It's all about learning and growing, and the **door to other opportunities will open** up as you gain experience.
**Remember, you're still in your 20s and there's plenty of time to explore different options! **
It's always better to be curious and adaptable. So don't be afraid to try something new!
In a nutshell: **continuous learning leads to better pay**.

1,904,252 | The Advantages of Task Order Contracts for Government Projects | Discover how task order contracts are revolutionizing government projects by adding flexibility, efficiency, and cost-effectiveness. | 0 | 2024-06-28T13:32:05 | https://www.govcon.me/blog/the_advantages_of_task_order_contracts_for_government_projects | governmentcontracts, projectmanagement, procurement | # The Advantages of Task Order Contracts for Government Projects
In the complex labyrinth of government procurement, **Task Order Contracts** (TOCs) emerge as a beacon of efficiency and adaptability. These contracts are a game-changer, offering a streamlined approach to managing government projects. Let's dive deep into how TOCs revolutionize public sector project management.
## What are Task Order Contracts?
Task Order Contracts are a type of **indefinite delivery, indefinite quantity (IDIQ)** contract. Unlike traditional procurement methods where the scope, timeline, and cost are rigidly predefined, TOCs provide a framework agreement with flexibility in execution. They authorize tasks as needed, allowing for an adaptable and responsive project management process.
### Key Characteristics of Task Order Contracts:
1. **Flexibility**: Adapt tasks as project needs evolve.
2. **Efficiency**: Simplified procurement for recurring needs.
3. **Cost-Effectiveness**: Competitive pricing through predefined rates.
4. **Speed**: Accelerated initiation and completion of tasks.
## Advantages of Task Order Contracts
### 1. Enhanced Flexibility
One of the hallmark advantages of TOCs is unparalleled flexibility. Government agencies can swiftly pivot and reallocate resources based on evolving project requirements without undergoing a lengthy procurement process each time.
- **Scalability**: Whether the project scope expands or contracts, TOCs accommodate changes smoothly.
- **Adaptability**: New tasks can be introduced and executed promptly, supporting dynamic project environments.
### 2. Increased Efficiency
By utilizing a single contract to authorize multiple tasks, TOCs significantly reduce the time and bureaucratic overhead associated with procurement.
- **Streamlined Processes**: Agencies issue task orders under a single overarching contract, bypassing repetitive procurement cycles.
- **Consistency**: With predefined terms and conditions, agencies and contractors maintain a consistent understanding throughout the contract lifecycle.
### 3. Cost-Effectiveness
TOCs enhance fiscal prudence by locking in competitive rates and providing budgetary predictability.
- **Economies of Scale**: Leveraging a single contract for multiple tasks yields cost advantages.
- **Predictable Budgeting**: Pre-negotiated rates aid in accurate forecasting and fiscal planning.
### 4. Rapid Deployment
In scenarios demanding quick responses, such as emergency management or unforeseen project pivots, TOCs come to the rescue.
- **Expedited Start**: Skip the prolonged bid solicitation and contracting phases.
- **Timely Execution**: Prompt initiation and completion of tasks ensure timely delivery of project outcomes.
## Real-World Applications of Task Order Contracts
### IT Services
Government agencies frequently use TOCs for IT services, such as software development, cybersecurity, and network maintenance. The flexibility to initiate, scale, and adjust tasks ensures that evolving technological needs are met without disruption.

1,904,250 | Connect to Azure SQL in R via Entra ID / AAD tokens from Azure CLI | One of the best features of the Azure SQL server is that you can connect to your database using your... | 0 | 2024-06-28T13:31:15 | https://dev.to/kummerer94/connect-to-azure-sql-in-r-via-entra-id-aad-tokens-from-azure-cli-3pn8 | r, sqlserver, azure | One of the best features of the Azure SQL server is that you can connect to your database using your Azure Active Directory (AAD, now called Entra ID) identity.
This works by retrieving an authentication token from Entry ID and then specifying this in the pre-connection attribute `SQL_COPT_SS_ACCESS_TOKEN`. If you are interested in the details, you can checkout the [issue about the implementation in the `odbc` package for R](https://github.com/r-dbi/odbc/issues/299).
This method does not only work for R but for any language that provides a package for an odbc driver that supports it. More information can be found in the [Microsoft docs for Python](https://learn.microsoft.com/en-us/azure/azure-sql/database/azure-sql-python-quickstart?view=azuresql&tabs=windows%2Csql-inter) or a [tutorial](https://medium.com/@everton_b.o/how-to-connect-to-azure-sql-database-with-mfa-using-python-on-macos-linux-de11cfdefb63) that explains the necessary steps in more detail.
Let's go back to R. First, you need to use the [`odbc`](https://github.com/r-dbi/odbc/) package for R and install the [Microsoft ODBC driver for SQL Server](https://learn.microsoft.com/de-de/sql/connect/odbc/microsoft-odbc-driver-for-sql-server?view=sql-server-ver16). You have probably installed the driver before if you have been connected to your sql server.
## Retrieve the token
There are multiple ways to retrieve a token. If you are developing locally, one of the easiest ways is to use Azure CLI. Make sure you have [Azure CLI](https://learn.microsoft.com/de-de/cli/azure/install-azure-cli) installed.
Make sure that you are logged by running this command in a terminal: `az login --allow-no-subscriptions`. The flag `--allow-no-subscriptions` makes sure you are able to retrieve a token even if you have no Azure subscriptions.
Then, you can retrieve a token. I am using the [`withr`](https://github.com/r-lib/withr) package here to make my life easier:
```R
result <- withr::with_tempfile("tf", {
suppressWarnings({
token <- system2(
"az",
c(
"account get-access-token",
"--resource https://database.windows.net",
"--query accessToken",
"--only-show-errors",
"--output yaml"
),
stdout = TRUE,
stderr = tf
)
})
system2error <- readLines(tf)
list(token = token[1], error = system2error)
})
print(result$token)
```
This should print the token in your R console. **Please note: this token is like a password. Please handle it with care.**
## Connect to the database
You can check the attributes of this JWT using a handy tool from Microsoft directly: [jwt.ms](https://jwt.ms/). It is safe to post your token there.
Finally, you have to connect to your server:
```R
con <- DBI::dbConnect(
odbc::odbc(),

> We are Trigger.dev, a background job platform with no timeouts for TypeScript developers. Check us out on [GitHub](https://github.com/triggerdotdev/trigger.dev) and give us a ⭐
## The discovery
At around 11pm local time (10pm UTC) on Thursday June 20, we were alerted to some issues in our production services powering the Trigger.dev cloud, as some of our dashboard/API instances started crashing.
We hopped on to our AWS production dashboard and saw that the CPU usage of our instances were really high and growing.
Combing through the logs on the crashed instances, we came across various errors, such as Prisma transaction timeouts:
```
Error: Invalid `prisma.taskAttempt.create()` invocation:Transaction API error: Transaction already closed: A query cannot be executed on an expired transaction. The timeout for this transaction was 5000 ms, however 6385 ms passed since the start of the transaction.
```
Followed by a message from Prisma stating they were unable to find the schema.prisma file and an uncaught exception, leading to the process exiting:
```
Error: Prisma Client is unable to find the Prisma schema file for this project. Please make sure the file exists at /app/prisma/schema.prisma.
```
We were puzzled by these errors, as the load on our primary database was consistently under 10% and the number of connections was healthy. We were also seeing other errors causing crashing, such as sending WebSocket messages to an already closed connection (which yes, [throws an exception](https://github.com/websockets/ws/issues/1515))
At the same time, we noticed that our network traffic was spiking, which was odd as we weren't seeing a corresponding increase in requests to our API:
Just past 1am local time, we deployed a couple things we had hoped would fix the issue (spoler: they did not). While waiting for the deploy to complete, I hit our metrics endpoint and was hoping to find some clues. I indeed did find something:
The deploy finished and the CPU usage dropped and the crashes stopped, so we were hopeful we had fixed the issue and went to bed.
## The issue returns
The next morning, we woke up to the same issue. The CPU usage was high again, the database was steady, and the network traffic was high. We were back to square one.
We had a hunch that if we could get a better idea behind the spikes in network traffic, we could find the root cause of the issue. We had access to AWS Application Load Balancer logs, so we setup the ability to query them [in Athena](https://docs.aws.amazon.com/athena/latest/ug/application-load-balancer-logs.html) and started by looking at the IPs with the most usage:
```sql
SELECT
client_ip,
COUNT(*) as request_count,
sum(received_bytes) / 1024 / 1024 as rx_total_mb,
sum(sent_bytes) / 1024 / 1024 as tx_total_mb
FROM
alb_logs
WHERE
day = '2024/06/20'
GROUP BY
client_ip
ORDER BY
tx_total_mb desc;
```
Which showed a pretty clear winner:
That's 21GB of data used by a single IP address in a single day. We wrote another query to see what paths this IP was hitting and causing the high network traffic:
```sql
SELECT
client_ip,
COUNT(*) as request_count,
min(time) as first_request,
max(time) as last_request,
sum(received_bytes) / 1024 / 1024 as rx_total_mb,
sum(sent_bytes) / 1024 / 1024 as tx_total_mb,
request_verb,
request_url
FROM
alb_logs
WHERE
day = '2024/06/20'
and client_ip = '93.xxx.xx.155'
GROUP BY
client_ip,
request_verb,
request_url
ORDER BY
tx_total_mb desc
limit 1000;
```
Most of the traffic was coming from just a few different paths, but they were all pointing to our v3 run trace view (just an example):
But the query above showed just a few paths, with thousands of requests each. We dug into the database and saw that these runs had 20k+ logs each, and our trace view lacked pagination. We also "live reload" the trace view as new logs come in, at most once per second.
So someone was triggering a v3 run, and viewing the trace view, as 20k+ logs came in, refreshing the entire page every second. This was causing the high network traffic, but doesn't explain the high CPU usage.
The next step to uncovering the root cause was to instrument the underlying code with some additional telemetry. Luckily we already have OpenTelemetry setup in our application, which sends traces to [Baselime.io](https://baselime.io). After adding additional spans to the code we started seeing traces like this:
As you can see in that trace above, a large amount of time was being spent inside the `createSpans` span. After about 30 seconds of digging, it was pretty clear what the issue was:
```ts
// This isn't the actual code, but a simplified version
for (const log of logs) {
// remember, 20k+ logs
const parentSpan = logs.find((l) => log.parentId === l.id);
}
```
Yup, that's a nested loop. We were iterating over 20k+ logs, and for each log, we were iterating over all the logs again to find the parent log (20k \* 20k = 400m). In Big O notation, this is O(n^2), which is not great (it's really bad).
We fixed the issue by creating a map of logs by ID, and then iterating over the logs once to create the spans. We quickly deployed the fix (along with limiting live-reloading the trace view when there are less than 1000 logs) and the CPU usage dropped, the network traffic dropped, and the crashes stopped (for now).
With this one issue fixed, we returned our attention to the event loop lag we had discovered the night before. We had squashed one instance of it, but we had a feeling this wasn't the only place it was causing issues.
Before we dive into how we discovered and fixed the rest of our event loop lag issues, let's take a step back and explain what event loop lag is.
## Event loop lag: a primer
Node.js only has a small amount of threads of operation, with the event-loop belonging to the main thread. That means that for every request that comes in, it's processed in the main thread.
This allows Node.js services to run with much more limited memory and resource consumption, as long as _the work being done on the main thread by each client is small_.
In this way Node.js is a bit like your local coffee shop, with a single barista. As long as no-one orders a Double Venti Soy Quad Shot with Foam, the coffee shop can serve everyone quickly. But one person can slow the whole process down and cause a lot of unhappy customers in line.
So how can this possibly scale? Well, Node.js actually will offload some work to other threads:
- Reading and writing files (libuv) happens on a worker thread
- DNS lookups
- IO operations (like database queries) are done on worker threads
- Crypto and zlib, while CPU heavy, are also offloaded to worker threads
The beauty of this setup is you don't have to do anything to take advantage of this. Node.js will automatically offload work to worker threads when it can.
The one thing Node.js asks of you, the application developer, is to fairly distribute main-thread work between clients. If you don't, you can run into event loop lag, leading to a long queue of angry clients waiting for their coffee.
Luckily, the Node.js team has published a pretty comprehensive guide on how to avoid event loop lag, which you can find [here](https://nodejs.org/en/learn/asynchronous-work/dont-block-the-event-loop).
## Monitoring event loop lag
After deploying the fix for the nested loop issue, we wanted to get a better idea of how often we were running into event loop lag. We added an event loop monitor to our application that would produce a span in OpenTelemetry if the event loop was blocked for more than 100ms:
```ts
import { createHook } from "node:async_hooks";
import { tracer } from "/blog/event-loop-lag/v3/tracer.server";
const THRESHOLD_NS = 1e8; // 100ms
const cache = new Map<number, { type: string; start?: [number, number] }>();
function init(
asyncId: number,
type: string,
triggerAsyncId: number,
resource: any
) {
cache.set(asyncId, {
type,
});
}
function destroy(asyncId: number) {
cache.delete(asyncId);
}
function before(asyncId: number) {
const cached = cache.get(asyncId);
if (!cached) {
return;
}
cache.set(asyncId, {
...cached,
start: process.hrtime(),
});
}
function after(asyncId: number) {
const cached = cache.get(asyncId);
if (!cached) {
return;
}
cache.delete(asyncId);
if (!cached.start) {
return;
}
const diff = process.hrtime(cached.start);
const diffNs = diff[0] * 1e9 + diff[1];
if (diffNs > THRESHOLD_NS) {
const time = diffNs / 1e6; // in ms
const newSpan = tracer.startSpan("event-loop-blocked", {
startTime: new Date(new Date().getTime() - time),
attributes: {
asyncType: cached.type,
label: "EventLoopMonitor",
},
});
newSpan.end();
}
}
export const eventLoopMonitor = singleton("eventLoopMonitor", () => {
const hook = createHook({ init, before, after, destroy });
return {
enable: () => {
console.log("🥸 Initializing event loop monitor");
hook.enable();
},
disable: () => {
console.log("🥸 Disabling event loop monitor");
hook.disable();
},
};
});
```
The code above makes use of `node:async_hooks` to capture and measure the time spent between the `before` and `after` hooks. If the duration between the two is greater than 100ms, we create a span in OpenTelemetry, making sure to set the `startTime` to the time the `before` hook executed.
We deployed the monitor on Friday afternoon and waited for the results. Around 10pm local time, we started seeing spans being created with pretty large durations:
## Event loop lag whack-a-mole
Starting the morning of Monday the 24th, we started on [a PR](https://github.com/triggerdotdev/trigger.dev/pull/1186) to fix as many of the event loop lag issues as we could. We submitted and deployed the PR around 10am UTC on Thursday the 27th with the following fixes:
- Added a limit of 25k logs to the trace view (after discovering a run with 222k logs). Added a "download all logs" button to allow users to download all logs if they needed them.
- Added pagination to our v2 schedule trigger list after we saw a 15s lag when a user had 8k+ schedules.
- Added a hard limit of 3MB on the input to a v2 task (after realizing we didn't have a limit at all), which matches the output limit on v2 tasks.
- Importantly, we changed how we calculated the size of the input and output of a v2 task. Previously, we were using `Buffer.byteLength` after having parsed the JSON of the request body. This was causing the event loop to block while calculating the size of the input and output. We now calculate the size of the input and output before parsing the JSON, using the `Content-Length` header of the request.
- We use Zod to parse incoming JSON request bodies, and removing the keys for the input and output of v2 tasks and handling them separately.
After deploying these fixes, we saw a significant drop in the number of spans being created by the event loop monitor:
We now have alerts setup to notify us if any event loop lag over 1s is detected, so we're able to catch and fix any new issues that arise.
## Next steps and takeaways
While most of the event-loop lag issues have been fixed, we still have more work to do in this area, especially around payload and output sizes of tasks in v3. We already support much larger payloads and outputs in v3 as we don't store payloads/outputs larger than 512KB in the database, but instead we store them in an object store (Cloudflare R2).
But v3 payloads are still parsed in our main thread, but in an upcoming update we're going to be doing 2 things to help with this:
1. For tasks triggered inside other tasks, we're going to upload large payloads to the object store and pass a reference to the payload when triggering the task. This will allow us to avoid parsing the payload in the main thread in our service.
2. For tasks triggered from client servers, and full payloads are being sent in the request body, we're going to stream the payload to the object store using `stream-json` (we have already built a prototype of this working).
More importantly, we now have a much better understanding of what it takes to run a reliable Node.js service in production that can handle a large number of clients. Going forward, we're going to be more careful in designing our code to avoid event loop lag.
## Addendum: serverless and event loop lag
Trigger.dev is implemented as a long-lived Node.js process, which as you can see above, takes some additional work to ensure that a single client can't block the event loop for everyone else. This is a common issue with long-lived Node.js processes, and is one of the reasons why serverless is so popular.
But serverless isn't a silver bullet. While serverless functions are short-lived, they still run on a single thread, and can still run into event loop lag. This is especially true if you're using a serverless function to handle a large number of clients, or if you're doing a lot of synchronous work in your function.
To keep request latency low, function instances are kept warm for a period of time after they're booted (known as a cold-boot). This means that while this event loop lag issue is mitigated somewhat by having many more instances running, it's still something you need to be aware of when building serverless Node.js applications. You can read more about this issue [here](https://medium.com/radient-tech-blog/aws-lambda-and-the-node-js-event-loop-864e48fba49).
### Background jobs
If you are running a long-lived Node.js service, requests aren't the only source of event loop lag that you need to be aware of. Offloading long-running or queued tasks inside the same Node.js process can also cause event loop lag, which will slow down requests and cause issues like the ones we experienced.
This is one reason why the pattern of using serverless for background jobs is so popular. By running background jobs in a separate process, you can avoid event loop lag issues in your main service and scale up and down to handle changing workloads. And serverless can be a great fit, but still requires careful design to avoid event loop lag and timeouts.
[Trigger.dev v3](https://trigger.dev) is now in Developer Preview and takes an approach that combines the best of both worlds. We deploy and run your background task code in a separate process, completely isolated from your main service and from each other, without worrying about timeouts. If you'd like to try it out, please [sign up for the waitlist](https://cloud.trigger.dev).

1,904,249 | The Vacuum Balloon Exploring the Science and Feasibility of Lifting Payloads to Space | This blog post explores the intriguing concept of using a vacuum balloon to lift payloads to space. By examining the physics behind this idea, including buoyancy, atmospheric pressure, and material properties, we delve into the challenges and potential of this innovative approach to space exploration. | 0 | 2024-06-28T13:29:44 | https://www.rics-notebook.com/blog/inventions/TheVacuumBalloon | vacuumballoon, spaceexploration, physics, buoyancy | # 🎈 The Vacuum Balloon: A Revolutionary Concept in Space Exploration? 🎈
As humanity continues to push the boundaries of space exploration, innovative ideas for reaching the final frontier are constantly emerging. One such concept is the vacuum balloon – a lightweight, hollow structure that uses the principle of buoyancy to lift payloads to space. In this blog post, we'll explore the science behind this intriguing idea and examine whether it could revolutionize the way we send objects into space.
# 🧪 The Physics Behind the Vacuum Balloon 🧪
To understand the concept of the vacuum balloon, we first need to delve into the fundamental physics principles at play. The key concepts involved are:
1. **Buoyancy**: Buoyancy is the upward force exerted on an object immersed in a fluid (in this case, the atmosphere). An object will float if its density is less than that of the surrounding fluid.
2. **Atmospheric Pressure**: Earth's atmosphere exerts pressure on objects due to the weight of the air above them. As altitude increases, atmospheric pressure decreases.
3. **Vacuum**: A vacuum is a space devoid of matter, including air. In a perfect vacuum, there is no pressure.
The idea behind the vacuum balloon is to create a structure that is essentially empty inside, like a vacuum, making it significantly less dense than the surrounding atmosphere. As a result, the balloon would experience a strong upward buoyant force, allowing it to lift a payload to high altitudes or even to the edge of space.
# 🌌 The Math Behind the Concept 🌌
To determine whether a vacuum balloon could work, we need to consider the mathematical relationships between the balloon's size, the payload's weight, and the atmospheric conditions at different altitudes.
The buoyant force (F_b) acting on the balloon can be calculated using Archimedes' principle:
F_b = ρ_air × g × V_balloon
Where:
- ρ_air is the density of air (which varies with altitude)
- g is the acceleration due to gravity (9.81 m/s^2)
- V_balloon is the volume of the balloon
For the balloon to lift a payload, the buoyant force must be greater than the combined weight of the balloon material and the payload:
F_b > (m_balloon + m_payload) × g
Where:
- m_balloon is the mass of the balloon material
- m_payload is the mass of the payload
As the balloon rises, the density of the surrounding air decreases, reducing the buoyant force. The balloon will continue to ascend until it reaches an altitude where the buoyant force equals the combined weight of the balloon and payload, at which point it will float like a bobber on the surface of water.
# 🚀 Challenges and Limitations 🚀
While the concept of a vacuum balloon is fascinating, there are several challenges and limitations to consider:
1. **Material Strength**: Creating a balloon that can withstand the pressure difference between the vacuum inside and the atmosphere outside while remaining lightweight is a significant engineering challenge. The material would need to be incredibly strong and resistant to punctures or tears.
2. **Atmospheric Drag**: As the balloon ascends, it will encounter atmospheric drag, which could slow its progress and limit its maximum altitude. The balloon's shape and surface properties would need to be optimized to minimize drag.
3. **Payload Protection**: The payload would need to be protected from the harsh conditions of the upper atmosphere and space, such as extreme temperatures, radiation, and vacuum. This would add weight and complexity to the overall system.
4. **Retrieval and Reusability**: Recovering the payload and potentially reusing the balloon would be another challenge. The balloon would need to be designed with retrieval mechanisms and be able to withstand the stresses of re-entry into Earth's atmosphere.
# 🔭 The Potential of Vacuum Balloons 🔭
Despite the challenges, the concept of vacuum balloons holds promise for certain space exploration applications. Some potential use cases include:
- **High-Altitude Scientific Missions**: Vacuum balloons could be used to lift scientific instruments to the upper atmosphere or even the edge of space for studying Earth's climate, monitoring weather patterns, or conducting astronomical observations.
- **Low-Cost Satellite Deployment**: Small satellites or CubeSats could potentially be launched using vacuum balloons, offering a more cost-effective alternative to traditional rocket launches for certain orbital altitudes.
- **Atmospheric Exploration on Other Planets**: Vacuum balloons could be adapted for use on other planets or moons with atmospheres, such as Mars or Titan, to study their atmospheric composition and dynamics.
# 🌟 Conclusion: A Concept Worth Exploring 🌟
The vacuum balloon is a fascinating concept that combines the principles of buoyancy, atmospheric pressure, and material science to potentially lift payloads to space. While there are significant engineering challenges to overcome, the idea holds promise for certain space exploration applications.
As we continue to push the boundaries of what's possible in space travel and scientific discovery, it's essential to explore innovative concepts like the vacuum balloon. By combining theoretical physics with advanced materials and engineering, we may one day see vacuum balloons becoming a reality and contributing to our ongoing quest to explore the cosmos. | eric_dequ |
1,904,104 | Master Base64 Decoding Today! | Introduction Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII... | 0 | 2024-06-28T12:34:12 | https://dev.to/keploy/master-base64-decoding-today-4dph | webdev, tutorial, python, ai |
**Introduction**
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation. It is commonly used to encode data that needs to be stored and transferred over media designed to deal with text. This ensures that the data remains intact without modification during transport. Understanding [Base64 decode](https://keploy.io/blog/community/understanding-base64-decoding) is crucial for anyone working with data transmission, encryption, or web development.
**What is Base64?**
Base64 encoding schemes are commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with textual data. This encoding helps to ensure that the data remains intact without modification during transport. Base64 is used commonly in a number of applications including email via MIME, as well as storing complex data in XML or JSON.
**How Base64 Works**
Base64 encoding takes three bytes, each consisting of eight bits, and represents them as four 6-bit base64 characters.
Here’s a simple illustration of how Base64 encoding works:
1. Original Binary Data: The data that needs to be encoded.
2. Convert to Binary: Each character is converted to its binary equivalent.
3. Split into 6-bit Groups: The binary data is split into groups of six bits.
4. Convert to Base64 Index: Each 6-bit group is converted to its corresponding Base64 index.
5. Convert to Base64 Characters: Each index is mapped to a Base64 character.
The Base64 Alphabet
The Base64 alphabet consists of 64 characters, which are:
• Uppercase letters: A-Z
• Lowercase letters: a-z
• Digits: 0-9
• Special characters: + and /
For example, the binary string 01000001 01000010 01000011 translates to ABC in ASCII, and would be encoded to QUJD in Base64.
Padding in Base64
Base64 encoding often includes padding characters (=) at the end of the encoded data. Padding is used to ensure the encoded data has a length that is a multiple of 4 bytes. The padding character = is used to fill the remaining space if the total number of bits in the original data is not a multiple of 6.
Why Use Base64?
Base64 is used in various scenarios where binary data needs to be encoded into text. Some common uses include:
1. Email Attachments: Email protocols were originally designed to handle plain text. To send binary files like images or documents as attachments, they need to be encoded into a text format.
2. Embedding Binary Data in Web Pages: Data URLs, which embed data directly in web pages, use Base64 encoding to represent the data as text.
3. Data Storage: When storing binary data in databases or JSON/XML, Base64 ensures data integrity by converting binary data into text.
Decoding Base64
Decoding Base64 is essentially the reverse of the encoding process. Here’s how it works:
1. Convert Base64 Characters to Binary: Each Base64 character is converted back to its corresponding 6-bit binary sequence.
2. Concatenate Binary Sequences: The binary sequences are concatenated to form a single binary string.
3. Split into 8-bit Groups: The concatenated binary string is split into 8-bit groups (bytes).
4. Convert to Original Data: Each 8-bit group is converted to its original character.
Implementing Base64 Decoding
Let's look at some examples of how Base64 decoding can be implemented in different programming languages.
Python
```
python
Copy code
import base64
# Example Base64 string
encoded_str = "SGVsbG8gV29ybGQh"
# Decode Base64 string
decoded_bytes = base64.b64decode(encoded_str)
decoded_str = decoded_bytes.decode('utf-8')
print(decoded_str) # Output: Hello World!
```
```
JavaScript
javascript
Copy code
// Example Base64 string
let encodedStr = "SGVsbG8gV29ybGQh";
// Decode Base64 string
let decodedStr = atob(encodedStr);
console.log(decodedStr); // Output: Hello World!
```
Java
```
java
Copy code
import java.util.Base64;
public class Base64DecodeExample {
public static void main(String[] args) {
// Example Base64 string
String encodedStr = "SGVsbG8gV29ybGQh";
// Decode Base64 string
byte[] decodedBytes = Base64.getDecoder().decode(encodedStr);
String decodedStr = new String(decodedBytes);
System.out.println(decodedStr); // Output: Hello World!
}
}
```
Common Pitfalls
While Base64 encoding and decoding is straightforward, there are a few common pitfalls to watch out for:
1. Padding: Incorrect handling of padding characters (=) can lead to decoding errors.
2. Character Encoding: Ensure the correct character encoding is used when converting between strings and bytes.
3. Data Corruption: Verify the integrity of the data before and after encoding/decoding to avoid data corruption.
Conclusion
Base64 encoding is a powerful tool for converting binary data into a text format that can be easily transmitted and stored. Whether you’re sending email attachments, embedding data in web pages, or storing binary data in a text-based format, understanding Base64 decoding is essential. By mastering the concepts and techniques of Base64 encoding and decoding, you can ensure data integrity and compatibility across various platforms and applications.
By following this guide, you now have a solid foundation in Base64 decoding, empowering you to handle text and binary data with confidence.

1,902,469 | Angular Form Architecture: Achieving Separation of Concerns with a FormHandlerService | Introduction In my previous articles, I've focused on managing the data flow in our... | 27,664 | 2024-06-28T13:28:45 | https://dev.to/cezar-plescan/angular-form-architecture-achieving-separation-of-concerns-with-a-formhandlerservice-5a7n | angular, tutorial, forms, service | ## Introduction
In my previous articles, I've focused on managing the data flow in our Angular user profile form, separating concerns between components and services. We successfully extracted the data access logic into a `UserService` and created a `HttpHelperService` to handle form data preparation. While this was a great step towards a cleaner architecture, we can further refine our form handling to enhance maintainability and reusability.
In this article, I'll tackle the challenge of managing form related logic within our Angular component. I'll focus on decoupling this logic from the component core responsibility of UI interactions, ensuring that our code adheres to the **Single Responsibility Principle (SRP)** and is more adaptable to future changes.
#### What I'll cover here
I'll guide you through the following steps:
- **Identifying form handling logic** - pinpoint specific methods and properties within the `UserProfileComponent` that relate to form management.
- **Creating the `FormHandlerService`** - a new service to house the extracted form handling logic.
- **Implementing reusable methods** - craft generic and reusable methods in the service to handle tasks like form updates, validation, and state management.
- **Integrating the service with the component** - modify the `UserProfileComponent` to delegate form related operations to the `FormHandlerService`.
- **Considering alternatives and best practices** - explore different approaches for organizing and sharing form handling logic, discussing their pros and cons.
By the end of this article, you'll have a deeper understanding of how to apply the Single Responsibility Principle to Angular forms, create reusable services for form logic, and build more maintainable and flexible frontend applications.
#### _A quick note_:
- _This article builds upon the concepts and code developed in previous articles in this series. If you're new here, I highly recommend catching up on the earlier articles to make the most of this one_.
- _You can find the starting point for the code I'll be working with in the `17.error-interceptor` branch of the [repository](https://github.com/cezar-plescan/user-profile-editor/tree/17.error-interceptor)_.
## Dealing with the form logic in the component
As I examine the [user-profile.component.ts](https://github.com/cezar-plescan/user-profile-editor/blob/17.error-interceptor/src/app/user-profile/user-profile.component.ts) file, I see a lot of code related to form handling. This includes things like updating the form values, displaying error messages, or figuring out whether the form has been changed.
I want to clean things up and make my code more organized. So, I'm going to follow the **separation of concerns principle** and move some of this form handling logic out of the component and into a new service. This way, the component can focus on its main job: managing how the form looks and feels for the user.
### Finding the right pieces to extract
I've spotted two methods that seem like good candidates for moving to a separate service: `updateForm()` and `setFormErrors()`.
The `updateForm()` method updates the form values, and it doesn't really depend on anything else in the component. It's a pretty general function that could be used with any form.{% embed https://gist.github.com/cezar-plescan/25f89223023b9e86a513fe04af3dcd5b %}
The second one, `setFormErrors()`, handles setting error messages on the form based on a response from the server. It's also not specific to this component; it could be used with other forms too. {% embed https://gist.github.com/cezar-plescan/6e94cb5839ebb9841ea2c0e5f0ac5ebe %}
There are other methods that work with the form too, like `restoreForm`, `isFormPristine`, `isSaveButtonDisabled`, or `isResetButtonDisabled`, but I'll tackle those later. For now, I want to simplify the component and extract the logic from `updateForm()` and `setFormErrors()` methods into a new service.
## Creating the `FormHandlerService`
I'll use the Angular CLI to create a new service in the `src/app/services` folder: `ng generate service form-handler`. Then, I'll move the `updateForm()` and `setFormErrors()` methods into this new service. Here's what the `FormHandlerService` looks like after moving the code: {% embed https://gist.github.com/cezar-plescan/94d2f7c49521243e9cbd1ce0f3edd8ba %}
At this moment the app is broken because the component doesn't have those methods anymore, and the service doesn't know which form to work on.
### Fixing the service code
I'll update the two methods to accept the form instance as a parameter: {% embed https://gist.github.com/cezar-plescan/592bd92e76cf764c5cc6142789f17c0e %}
Additionally, I'll create a separate file `src/app/shared/types/form.type.ts` containing the definition of the `FormModel` interface: {% embed https://gist.github.com/cezar-plescan/02c0fdcf439c7c51a5ca9882832059e1 %}
I've also made the service more flexible by using generic types `<FormType extends FormModel, DataType extends FormType>` so that it can work with different kinds of forms and data structures.
### Updating the `UserProfileComponent`
Now, let's update our component to use this new service:
- remove the original `updateForm()` and `setFormErrors()` methods from the component.
- inject the `FormHandlerService` into the component.
- call the service methods where needed, passing in the `form` object as an argument.
Here is the updated component code:{% embed https://gist.github.com/cezar-plescan/38c33d2be6607f88731b4eb2a87dca7b %}
### The power of reusability
With these changes, we've successfully extracted some of the form handling logic into a separate service. This makes the component cleaner, easier to understand, and more focused on its job of managing the UI. The `FormHandlerService` is now reusable; we can use it with other forms in our application, too.
### `isFormPristine()` method
Next I'll examine the logic in the `isFormPristine()` method. It checks if the form value matches the last saved data from the backend. This method relies on two things: the original user data and the current value of the form.
The logic inside `isFormPristine()` isn't specific to our component, so it's a good candidate for moving to the `FormHandlerService`. This way, we can reuse it with other forms throughout the application. To make this happen, I'll pass both the form instance and the last saved data as parameters to the method: {% embed https://gist.github.com/cezar-plescan/0d8d57c70e75ac153cf3c1e34e57ff5d %}
Then, I'll update the `UserProfileComponent`: remove the `isFormPristine()` method and replace it with `this.formHandlerService.isFormPristine()` in the two methods where it's used:{% embed https://gist.github.com/cezar-plescan/5872673e093b310dda2c41e48184ce24 %}
### Form button logic
But wait, there's more! The logic in the `isSaveButtonDisabled()` and `isResetButtonDisabled()` methods also looks pretty reusable. These methods determine when to disable the "Save" and "Reset" buttons, depending on whether the form is valid, pristine, or if a save operation is in progress.
Let's refactor these too and move them into our service:{% embed https://gist.github.com/cezar-plescan/0475f5c0387569a4b1e9152717dbe689 %}
And now update the `UserProfileComponent`, by simply delegating the calls to these new service methods:{% embed https://gist.github.com/cezar-plescan/6fd5753dc796025ca9c55589627d18bf %}
You might be thinking, _"Whoa, this is a lot of arguments to pass to the service!"_ And you're right, it does look like more code at first. But trust me, this will really pay off when you reuse the `FormHandlerService` in other components later on.
### `restoreForm()` method
Taking a closer look at the `restoreForm()` method, I see that it's responsible for resetting the form to its initial or pristine state. This logic is directly related to the form and its values, making it another candidate for extraction into our `FormHandlerService`.
By moving this method to the service, we:
- consolidate the form logic, keeping all form related operations centralized within the `FormHandlerService`, adhering to the Single Responsibility Principle (SRP).
- enhance reusability, making the `restoreForm` logic available to other components that might need it.
- simplify the component, removing unnecessary code from the `UserProfileComponent`, allowing it to focus more on its core UI responsibilities.
Let's see the refactored code of both the service and the component:{% embed https://gist.github.com/cezar-plescan/b508247d97d4735e53d7d769b484329d %}{% embed https://gist.github.com/cezar-plescan/a3330389eb1e745e552bc6cf32abb30b %}
## Separate service instance for each component
You might have noticed that all of the service methods currently require the form object as an argument. This can lead to a bit of extra work when calling these methods repeatedly. What if we could pass the form only once when the service is first injected into the component?
This would involve storing the form object within the service instance itself. To achieve this, we'll need to have multiple instances of the `FormHandlerService`, one for each component that injects it. Fortunately, Angular's dependency injection system allows us to easily provide services at the component level, ensuring each component gets its own dedicated instance.
### Modifying the `FormHandlerService`
Here's the updated service class:{% embed https://gist.github.com/cezar-plescan/15ed68892c7324f59d2120e42bad3f51 %}
The key changes:
- I've removed `{providedIn: 'root'}`. This ensures the service is no longer a singleton shared across the entire application.
- The service now contains the `form` property to store the form instance.
- The `initForm` method allows the component to initialize the service with its specific form instance.
- I've removed the `form` parameter from all the other methods and instead used the local reference `this.form`.
### Providing the service at the component level
Here's how to provide the service in the `UserProfileComponent`:{% embed https://gist.github.com/cezar-plescan/034d332b3093ff4b1514e1d8432ddbef %}
Remember to remove the `this.form` argument from all the service methods within the component.
### Benefits and considerations
By creating a separate service instance for each component, we achieve the following:
- reduced overhead - avoid passing the form object to every method call.
- clearer intent - the component interaction with the service is more explicit, as it initializes the service with the form upon creation.
- isolated forms - each component manages its own form independently, preventing conflicts between different forms.
#### There's a tradeoff
Having multiple instances of a service can **consume more memory**, especially if we have many components with forms.
#### Balancing flexibility and performance
While this approach offers **isolation** and **convenience**, we should consider the potential memory impact in larger applications with numerous forms.
The best approach will depend on the specific requirements and scale of our application. In many cases, the benefits of isolation and cleaner code outweigh the minor performance overhead of multiple service instances.
## Wrapping up
In this article, I've focused on improving the `UserProfileComponent` by moving its form related logic to a dedicated `FormHandlerService`. We've accomplished the following:
- recognized that the component was violating the Single Responsibility Principle by handling too many unrelated concerns.
- extracted form related methods like `updateForm`, `setFormErrors`, `isFormPristine`, and button state logic into this new service.
- used TypeScript generics to make the service reusable with different form types and data structures.
- provided the service at the component level to ensure each form has its own isolated instance.
By separating the form handling logic into a dedicated service, we've made our `UserProfileComponent` cleaner, more focused, and easier to maintain.
### Where to find the code
The complete code for this refactoring can be found in the `18.form-service` branch of the [GitHub repository](https://github.com/cezar-plescan/user-profile-editor/tree/18.form-service).
Feel free to explore, experiment, and adapt this approach to your own Angular forms. This is just another step in the ongoing journey of refactoring and improving our application architecture.

## Svelte: The New Kid on the Block
### Overview
Svelte is a relatively new front-end framework developed by Rich Harris. Unlike React, which does most of its work in the browser, Svelte shifts that work into the compile step. This results in a drastically different approach to building web applications.
### Key Features
1. No Virtual DOM: Svelte compiles your code to highly efficient, imperative code that directly manipulates the DOM. This results in faster performance and smaller bundle sizes.
2. Reactivity: Svelte has a built-in reactivity system that is intuitive and easy to use. You can create reactive variables by simply declaring them with the let keyword.
3. Simplicity: Svelte's syntax is straightforward and easy to learn, making it accessible to beginners while still powerful for experienced developers.
### Why Svelte is Intriguing
Svelte's approach to compiling away the framework is revolutionary. The performance gains and smaller bundle sizes are impressive, and the reactivity system feels natural and less boilerplate-y than other frameworks. While I plan to use React primarily, Svelte offers a refreshing alternative that challenges conventional front-end paradigms.
## Conclusion
Both ReactJS and Svelte have their unique advantages. ReactJS offers a robust ecosystem and a mature framework that's proven in production. Svelte, on the other hand, provides an innovative approach with impressive performance benefits. Choosing between them depends on your project's requirements and your personal preference.
In the HNG Internship, I look forward to deepening my expertise in React, building on my existing knowledge, and possibly exploring Svelte for suitable projects. The journey so far has been like being with family, sharing ideas, and growing together. I can't wait to see what's next!

In our quest for technological advancement, we often stumble upon ideas that seem counterintuitive yet hold immense potential. One such concept is the reverse microwave – a device designed to rapidly cool objects rather than heat them. In this blog post, we'll delve into the physics behind this intriguing idea and explore its potential applications, from everyday convenience to cutting-edge quantum computing research.
# 🧪 The Physics of Rapid Cooling 🧪
To understand how a reverse microwave might work, we need to examine the fundamental principles of thermodynamics and heat transfer. The key concepts involved are:
1. **Heat Transfer**: The process by which thermal energy moves from one object or system to another.
2. **Thermal Radiation**: The emission of electromagnetic waves from all matter that has a temperature above absolute zero.
3. **Thermoelectric Cooling**: The use of the Peltier effect to create a heat flux between two different types of materials.
The reverse microwave concept aims to accelerate the cooling process by efficiently removing thermal energy from an object. This could be achieved through a combination of advanced cooling techniques, including thermoelectric cooling and controlled thermal radiation.
# 🌡️ The Math Behind the Chill 🌡️
To quantify the cooling process, we can use several equations from thermodynamics and heat transfer. Let's examine a few key equations:
1. **Newton's Law of Cooling**:
dQ/dt = hA(T - T_env)
Where:
- dQ/dt is the rate of heat transfer
- h is the heat transfer coefficient
- A is the surface area of the object
- T is the temperature of the object
- T_env is the temperature of the environment
2. **Thermoelectric Cooling Efficiency**:
COP = Q_c / W_in
Where:
- COP is the coefficient of performance
- Q_c is the heat removed from the cold reservoir
- W_in is the work input to the system
3. **Stefan-Boltzmann Law for Thermal Radiation**:
P = εσA(T^4 - T_env^4)
Where:
- P is the net radiated power
- ε is the emissivity of the object
- σ is the Stefan-Boltzmann constant
- A is the surface area of the object
- T is the temperature of the object
- T_env is the temperature of the environment
By optimizing these processes, a reverse microwave could theoretically cool objects much faster than conventional refrigeration methods.
# 🚀 Challenges and Innovations 🚀
Developing an efficient reverse microwave presents several challenges:
1. **Energy Efficiency**: Rapid cooling requires significant energy input. Optimizing the cooling process to minimize energy consumption is crucial.
2. **Uniform Cooling**: Ensuring even cooling throughout the object, especially for items with varying densities or compositions.
3. **Material Compatibility**: Designing a system that can safely cool a wide range of materials without causing damage or altering their properties.
4. **Size and Cost**: Creating a device that is compact and affordable enough for consumer use while still delivering rapid cooling performance.
To address these challenges, researchers are exploring innovative cooling technologies, such as:
- Advanced thermoelectric materials with higher efficiency
- Nano-engineered surfaces for enhanced thermal radiation
- Microfluidic cooling systems for precise temperature control
- AI-driven cooling algorithms to optimize performance for different objects
# 🌟 From Kitchen Counters to Quantum Computers 🌟
While the idea of a reverse microwave might seem like a luxurious kitchen appliance, its potential applications extend far beyond quickly chilling beverages. The development of rapid cooling technology could have significant implications for various fields, including:
1. **Food Preservation**: Rapid cooling can help preserve food quality and extend shelf life.
2. **Medical Applications**: Quick cooling of medical samples or pharmaceuticals could improve storage and transportation.

Hello everyone and welcome back to my blog. Today I will show you how to code a "Number guessing game" using Rust.
{% embed https://twitter.com/BatsouElef/status/1806680564038324566 %}
By the end of this tutorial, you'll not only have a fun challenging game but also:
* You'll learn how to generate random numbers for user-guessing
* You'll learn the basics like loops and input in Rust
Don't forget you can find all the code on my [GitHub profile](https://github.com/EleftheriaBatsou), there will be a link for this project at the end of this article.
## Code the Game
Open your favorite code editor, type in the terminal `cargo new your-project-name` and let's start!
Firstly, we need to import the standard library for input `use std::io::stdin;`, as we will need the user to input a number. Then, inside the `main()` we're going to create a loop and we'll name it: `outer_loop` , this is going to be a looping structure. Let's also declare a variable: `let _number: u32 = 10;` with a value of 10. This is the value that the user should guess. Finally, we're asking the user to pick a number: `println!("Pick a number (1 to 15) >>>");`
***Note****: You may be thinking that this is a random number guessing game but we just gave* `_number` *a static number... Wait for it! We'll change it to a random number in a bit 🤓.*
So far we have:
```rust
fn main() {
'_outer_loop: loop {
let _number: u32 = 10;
println!("Pick a number (1 to 15) >>>");
}
```
But, as we mentioned above, it'd be more interesting to generate a random number. So the user will guess a new number each time they run our game.
Let's continue coding...
After showing the message `Pick a number (1 to 15) >>>` we need to store the user's number. So, we're going to have another `loop` and declare a new mutable variable that's going to contain the new empty string. We also want to pass a reference where we're going to store the string, and that's why we've imported it above the standard input library. The standard input is going to read the `line` .
```rust
let mut line = String::new();
let _input = stdin().read_line(&mut line);
```
Time to define our `guess`. 😊
`let guess: Option = input.ok().mapor(None, || line.trim().parse().ok());`
In the above line of code, the `ok()` means that the reader is at the end of the line of the `input` the user entered. After this we have `mapor`: this is going to return the default value or apply functions to a value.
So we're going to take the line and we're going to trim it and parse that string in order to be an integer value (`line.trim().parse().ok()` ) so we can compare between the user's guess and the predefined number so the data types can be compatible for comparison.
Now, we can continue with `matching` the `_guess`. (And this is why needed the `Option`.)
```rust
match _guess{
None => println!("enter a number..."),
Some(n) if n == _number => {
println!("Bravo! You guessed it!");
break '_outer_loop;
}
.
.
.
}
```
* If the input is `None`, we're going to print a line that says `enter a number`, and if some number is entered, then we're going to compare between the user's input and the number that's predefined (which is still `10`, but wait for it...).
* If the user guessed the correct number, then we're going to print a line that says `Bravo, you guessed it!`. And we're going to `break` out of the `loop`. That's why we defined above the `_outer_loop`.
* If the user's `input` is less than the number that's predefined, we're going to print `Too low`, and if it's higher, we're going to print `Too high` and if anything else, we're going to throw an error and the loop will continue.
```rust
Some(n) if n < _number => println!("Too low"),
Some(n) if n > _number => println!("Too high"),
Some(_) => println!("Error!")
```
You can now run the program with `cargo run` but every time you play the game the `_number` will be 10. Let's fix that. 👇
## Random Number Generator
The first thing we need is to `import` the random range dependency. We'll need to go to cargo.toml and include this `rand = "0.8.3"` in `[dependencies]`.
```ini
[dependencies]
rand = "0.8.3"
```
And in `main.rs` we'll include `use rand::Rng;`
Now, instead of having this predefined number `10`, we're going to create a dynamic one.
```rust
// let _number: u32 = 10;
let _number: i32 = rand::thread_rng().gen_range(1..=15)
```
This `_number` will be of `integer 32` instead of `unassigned 32`. ***Note:*** *If you have defined your variable* `i32`*, then you will need to define the* `Option` *also* `i32`*, and vice versa*. Now this integer has access to `thread_rng` inside the random package that `gen_range` from 1 to 15.
Let's run the program...
## Run It
Use `cargo run` to run the program.
## Conclusion
That was our simple rust game. Feel free to experiment with rand, integer and unsigned numbers.

1,904,239 | Managing Terraform State Across AWS Accounts Using GitHub Actions | When working on a Terraform project, it's common to save the Terraform state file in the same AWS... | 0 | 2024-06-28T13:24:00 | https://dev.to/sepiyush/managing-terraform-state-across-aws-accounts-using-github-actions-cjh | terraform, aws, githubactions, cicd | When working on a Terraform project, it's common to save the Terraform state file in the same AWS account where resources are deployed. However, there may be scenarios where you need to maintain the state file in a separate AWS account for better security and access control. This blog post walks you through setting up such a configuration and updating your CI/CD pipeline accordingly.
### Initial Setup: Terraform Project and CI/CD Pipeline
Imagine you have a Terraform project that deploys AWS resources and saves the Terraform state file in the same AWS account. You also have a CI/CD pipeline using GitHub Actions that looks something like this:
```yaml
name: Deploy Terraform Infrastructure
on:
push:
branches:
- branch
jobs:
terraform:
runs-on: ubuntu-latest
permissions:
id-token: write
contents: read
steps:
- name: Checkout repository
uses: actions/checkout@v2
- name: Setup Terraform
uses: hashicorp/setup-terraform@v1
with:
terraform_version: 1.8.5
- name: Configure AWS Credentials
id: aws-creds
uses: aws-actions/configure-aws-credentials@v1
with:
role-to-assume: <your role>
aws-region: <your region>
- name: Initialize Terraform
run: terraform init -backend-config="region=region" -reconfigure -backend-config="bucket=bucket-name"
- name: Plan Terraform
run: terraform plan -var="your variables" -out tf.plan
- name: Apply Terraform
if: github.event_name == 'push'
run: terraform apply "tf.plan"
```
### Request: Storing State File in a Separate AWS Account
There may be a request to store the state file in a separate AWS account due to security reasons, such as limited access, read-only permissions, and more restrictive policies. Here's how to achieve this.
### One-Time Setup: Creating Resources in the New AWS Account
First, you need to create the required resources in the new AWS account using Terraform. This is separate from the Terraform code used to deploy your application infrastructure. The Terraform template for setting up the new account might look like this:
```hcl
resource "aws_iam_openid_connect_provider" "github" {
url = "https://${var.github_idp_domain}"
client_id_list = ["sts.amazonaws.com"]
thumbprint_list = [var.github_idp_thumbprint]
}
provider "aws" {
region = var.region
profile = var.aws_profile
}
# Create S3 bucket
resource "aws_s3_bucket" "my_bucket" {
bucket = var.bucket_name
}
resource "aws_s3_bucket_public_access_block" "public_access_block" {
bucket = aws_s3_bucket.my_bucket.id
block_public_acls = true
block_public_policy = true
ignore_public_acls = true
restrict_public_buckets = true
}
# Create IAM role
resource "aws_iam_role" "github_actions_role" {
name = "github-actions-role"
assume_role_policy = jsonencode({
Version = "2012-10-17",
Statement = [
{
Effect = "Allow",
Principal = {
Federated = "arn:aws:iam::${data.aws_caller_identity.current.account_id}:oidc-provider/${var.github_idp_domain}"
},
Action = "sts:AssumeRoleWithWebIdentity",
Condition = {
StringEquals = {
"${var.github_idp_domain}:aud" : "sts.amazonaws.com",
"${var.github_idp_domain}:sub" : "repo:Organisation/Repo:ref:refs/heads/Branch"
}
}
}
]
})
}
# Create IAM policy
resource "aws_iam_role_policy" "s3_upload_policy" {
name = "s3-upload-policy"
role = aws_iam_role.github_actions_role.id
policy = jsonencode({
Version = "2012-10-17",
Statement = [
{
Effect = "Allow",
Action = [
"s3:PutObject",
"s3:GetObject"
],
Resource = [
aws_s3_bucket.my_bucket.arn,
"${aws_s3_bucket.my_bucket.arn}/*"
]
}
]
})
}
data "aws_caller_identity" "current" {}
```
### Migrating the State File
To migrate the state file to the new AWS account, follow these steps:
1. **Pull the State File**: Download your current state file.
```sh
terraform state pull > terraform.tfstate
```
2. **Delete the .terraform Directory**: Remove the initialized Terraform state to force reinitialization.
```sh
rm -rf .terraform
```
3. **Reinitialize Terraform**: Reinitialize Terraform with the new backend configuration.
```sh
terraform init -backend-config="region=<region>" -backend-config="bucket=<new bucket>" -backend-config="profile=<new aws account>"
```
### Updating the CI/CD Pipeline
To use the profile functionality in the CI/CD pipeline, you can use the `mcblair/configure-aws-profile-action@v1.0.0` [action](https://github.com/marketplace/actions/configure-aws-profile), which supports profiles. Here’s how the updated CI/CD pipeline looks:
```yaml
name: Deploy Terraform Infrastructure
on:
push:
branches:
- branch
jobs:
terraform:
runs-on: ubuntu-latest
permissions:
id-token: write
contents: read
steps:
- name: Checkout repository
uses: actions/checkout@v2
- name: Setup Terraform
uses: hashicorp/setup-terraform@v1
with:
terraform_version: 1.8.5
- name: Configure AWS Credentials for Deployment
id: dev-aws-creds
uses: mcblair/configure-aws-profile-action@v1.0.0
with:
role-arn: <current-aws-account-to-deploy-aws-resources-role-arn>
aws-region: <region>
profile-name: old-aws-account
- name: Configure AWS Credentials for State File
id: infra-aws-creds
uses: mcblair/configure-aws-profile-action@v1.0.0
with:
role-arn: <new-aws-account-created-for-github-actions-to-save-tf-statefile-role-arn>
region: <region>
profile-name: new-aws-account
- name: Initialize Terraform
run: |
cd mist-deployment
terraform init -backend-config="region=<region>" -backend-config="bucket=<new bucket>" -backend-config="profile=new-aws-account" -reconfigure
- name: Plan Terraform
run: |
cd mist-deployment
terraform plan -var="profile=old-aws-account" -out tf.plan
- name: Apply Terraform
if: github.event_name == 'push'
run: |
cd mist-deployment
terraform apply "tf.plan"
```
### Conclusion
By following these steps, you can successfully migrate your Terraform state file to a separate AWS account while maintaining a smooth CI/CD pipeline. This approach enhances security by limiting access to the state file and allows for better management and control of your AWS resources. | sepiyush |
1,904,050 | Understanding Base64 Decoding | In the world of computer science and data transmission, encoding and decoding are fundamental... | 0 | 2024-06-28T12:08:38 | https://keploy.io/blog/community/understanding-base64-decoding |
In the world of computer science and data transmission, encoding and decoding are fundamental concepts. One of the most commonly used encoding schemes is Base64. This encoding method is widely used in various applications, from email encoding and web data transfer to encoding binary data for storage.
So let's explore more in detail about Base64 decoding, exploring its purpose, how it works, with some practical real life examples.
**What is Base64 ?**
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format, using a set of 64 characters - uppercase and lowercase letters, digits, and symbols.
The purpose of using Base64 is to ensure that data remains intact and is not modified during transport. This is particularly useful when transmitting data over media that are designed to handle text, such as email or HTTP. Encoding binary data into ASCII characters helps to prevent data corruption during transmission.
For example, consider the binary sequence 010011010110000101101100. When grouped into 6-bit segments, it becomes 010011 010110 000101 101100, which corresponds to the Base64 characters TWFs.
**What is Base64 Encoding Scheme ?**
The Base64 character set consists of 64 characters, which are used to represent the binary data in text form and each character represents a 6-bit binary sequence, enabling the encoding of binary data into a readable string format.
Padding and the Role of the = Character
When the length of the binary data is not a multiple of 6 bits, padding is required to complete the final segment. Base64 uses the = character for padding. Depending on the length of the binary data, one or two = characters may be added to the end of the encoded string to ensure it is properly formatted.
For instance, the binary data 010011010110000101101100 converts to TWFs, which requires no padding. However, if the binary data length is not divisible by 6, padding is added.
**How Base64 Decoding works ?**
Base64 Decode involves reversing the encoding process. Here's a step-by-step breakdown:
Convert Base64 Characters to Binary: Each Base64 character is converted back to its 6-bit binary representation.
Combine Binary Groups: The 6-bit binary groups are combined to form the original binary data.
Convert Binary to Original Data: The binary data is then converted back to its original format, such as text or binary file.
**Handling Padding During Decoding**
When decoding, the = characters are removed before the binary conversion. The decoder then interprets the binary data according to the Base64 character set.
**Example of Decoding a Base64 String**
Let's decode TWFu back to its original form:
TWFu corresponds to 010011 010110 000101 101110.
Combining these groups gives 010011010110000101101110.
Practical Applications
**Real-World Examples of Base64 Decoding**
Web APIs: Many web APIs return encoded image data in Base64. For instance, an image retrieved from an API might be encoded to ensure it can be included in a JSON response.
Email Attachments: When receiving an email with an attachment, the email client decodes the Base64 data to retrieve the original file.
**Tools and Libraries for Base64 Decoding**
Numerous tools and libraries are available for Base64 decoding across various programming languages:
Python: The base64 module provides functions for encoding and decoding.
```
import base64
decoded_data = base64.b64decode(encoded_data)
JavaScript: The atob function decodes a Base64 string.
let decodedData = atob(encodedData);
Java: The Base64 class in java.util provides methods for decoding.
byte[] decodedBytes = Base64.getDecoder().decode(encodedString);
```
**Why Base64 is Not Encryption**
It is crucial to understand that Base64 encoding is not a form of encryption. It is a reversible encoding scheme designed for data representation and transmission, not for securing data. Base64 encoded data can be easily decoded, making it unsuitable for protecting sensitive information.
**Potential Security Risks and Mitigation**
While Base64 itself is not insecure, using it as a security measure can be risky. To mitigate potential risks:
**Encryption**: Use proper encryption methods to secure sensitive data.
**Validation:** Validate Base64 input to prevent injection attacks.
Transport Layer Security: Ensure data transmitted over networks is encrypted using protocols like TLS.
**Conclusion**
Base64 encoding and decoding are vital tools in data transmission, enabling the conversion of binary data into text format for easy handling and transport. While not suitable for security purposes, Base64 plays a significant role in various applications, from web APIs to email systems. Understanding how to encode and decode Base64 can greatly enhance your ability to work with diverse data formats in modern computing environments. Explore the many applications of Base64 encoding and decoding to see how it can be leveraged in your projects.
**FAQs**
**What is Base64 encoding and why is it used?**
Base64 encoding is a method of converting binary data into an ASCII string format. It is used to ensure data integrity during transmission over media that are designed to handle text. By converting binary data into a text string, Base64 encoding allows data to be transported over text-based protocols such as email and HTTP without being altered or corrupted.
**How does Base64 encoding handle binary data that isn't a multiple of 6 bits?**
Base64 encoding handles binary data that isn't a multiple of 6 bits by using padding. Padding is done using the = character. If the binary data length is not divisible by 6, one or two = characters are added to the end of the Base64 encoded string to make the length a multiple of 4, ensuring proper encoding and decoding.
**Is Base64 encoding secure for transmitting sensitive data?**
No, Base64 encoding is not secure for transmitting sensitive data. Base64 is an encoding scheme, not an encryption method. It is designed for data representation and transmission, not for data security. Base64 encoded data can be easily decoded, so it should not be used to protect sensitive information. For secure data transmission, proper encryption methods should be used.
**Can you provide an example of Base64 decoding in Python?**
```
import base64
# Example Base64 encoded string
encoded_data = "SGVsbG8sIFdvcmxkIQ=="
# Decoding the Base64 encoded string
decoded_data = base64.b64decode(encoded_data)
# Converting bytes to string
decoded_string = decoded_data.decode('utf-8')
print(decoded_string) # Output: Hello, World!
```
This script decodes the Base64 string "SGVsbG8sIFdvcmxkIQ==" back to its original form, "Hello, World!".
**What are some common use cases for Base64 encoding?**
Base64 encoding is commonly used in various scenarios, including:
**Email Attachments**: Encoding binary files such as images and documents to be sent as part of an email.
**Web APIs**: Encoding binary data like images and files in JSON responses.
**Data Storage**: Storing binary data in text-based formats like databases or configuration files that do not support binary data.
**Embed Images in HTML/CSS**: Encoding small images directly in HTML or CSS files to reduce the number of HTTP requests.
**Data URLs**: Embedding data directly in URLs for small pieces of data, such as icons or short scripts. | keploy | |

There is a common... | 0 | 2024-06-28T13:23:15 | https://dev.to/marcopatino/prs-in-trunk-based-development-8n8 | code, webdev, productivity, discuss | Wait, PRs in Trunk Based Development? Yes, PRs in Trunk Based Development.
There is a common misunderstanding with TBD, which is that it always implies committing directly to main/trunk and pair programming. This is false.
I talk a lot about code reviews, devex, branching models and everything around them, as I’m the cofounder at [pullpo.to/phunt](http://pullpo.to/phunt).
One common feedback that I’ve got many times is:
> Code reviews through pull requests were made for open source. In proprietary software, we should do trunk based development (implying pair programming and committing directly to trunk)
>
I don’t totally agree with this claim. I’m going to explain why. To give a little bit of context…
## What is TBD (Trunk Based Development)?
Basically, what TBD says is that we should avoid creating **long-lived** branches other than the main branch (trunk). Developers should push new commits directly there or merge **short-lived** feature branches (will come back to this later). The only rule for every new push or merge to trunk is to not break the build. The CI must pass.
The main concept behind TBD, which I love, is that we should keep developers close to a production environment or its closest equivalent, the main branch. Compared to other obsolete branching methods like Git Flow, TBD increases ownership and responsibility among developers, which is good. It also allows us to be always ready to deploy, and as a consequence, it normally increases deployment frequency. Since we can reach production faster, it also substantially reduces cycle time and time to recover from failures.
All of this is great, but keep reading please, the interesting part is about to come:
## PRs and code reviews in TBD.
If you are committing directly to trunk, the only way to do a code review before the code gets to trunk is by pair programming. There is no alternative. If you want to do a code review (and, [most of the times](https://martinfowler.com/articles/ship-show-ask.html), you want to do a code review) you need to do pair programming.
But TBD is also compatible (and actually recommends) doing PRs and **short-lived feature branches.** I know some people who wont believe this, so I’m attaching an screenshot from the official TBD website. https://trunkbaseddevelopment.com/short-lived-feature-branches/
TBD also recommends pairing, as it has a lot of advantages: better communication, shorter feedback loops… The thing is, pair programming doesn’t work for everyone, all the time, for every task.
In my case, I love pairing for problems that require creative solutions, or when debugging, or when onboarding a new developer. But I often feel much more productive when working alone. Many times I cannot achieve flow state while pairing.
Other people are always super productive while pairing, for every type of task, and they love it.
We are humans. Humans are different.
If you create **short-lived feature branches** now you have both options for code reviews: pair programming and conventional code reviews. You can detect good opportunities for pairing and go for it. In the other cases, go for conventional code reviews.
> *Other benefit of creating short-lived branches:*
>
>
> Before pushing a new commit to a branch, first you have to pull the latest version of that branch. Depending on different factors this command can take time.
>
> Now imagine 50 devs working on the same repo constantly pushing commits to trunk. It may be difficult to find a time window where no one pushes and you can pull the latest version and push your code.
>
> This problem is solved with PRs and merge queues. GitHub has its own merge queue feature.
>
## My take.
- If everyone in your team is happy with always doing pair programming AND this is not a problem for hiring new devs AND you don’t have issues with the CI or with finding a long enough time window where you can pull and push with anyone changing trunk, then great! Pairing and committing to trunk is the best solution. If this condition is not met…
- Do short-lived feature branches, but they have to be **short-lived**. Short-lived means max 2 days and only one committer (1 dev or 1 pair programming duo). [Code review channels](pullpo.to/channels) can help keep PRs fast. This is important. Otherwise, you are not doing TBD.
- Learn how to identify good opportunities for pairing in your team. This is a trial and error process. Every person is different. Know yourself.
- Set up you CI to run on PRs. Pair programming duos can have the option to directly merge (or send to merge queue) to trunk if the CI passes. Individual devs may need 1 or 2 approvals before merging.

In this post we... | 0 | 2024-06-28T11:49:49 | https://dev.to/akshat0610/day-23-of-30-of-javascript-2042 | webdev, javascript, beginners, tutorial | Hey reader👋 Hope you are doing well😊
In the last post we have talked about Callbacks. In this post we are going to discuss about Promises.
So let's get started🔥
## Promises
Promises are used to handle Asynchronous Operations preventing callback hell and unmanageable code. A Promise is an object that will produce a single value some time in the future. If the promise is successful, it will produce a resolved value, but if something goes wrong then it will produce a reason why the promise failed.
It is something like when you make a promise either you fullfill it or tell your reasons why you didn't able to fullfill it.
So this is an example of Promise. If the condition is true `resolve` method is called else `reject()` method is called. If promise is fullfilled then "success" is printed else an error is caught.
Note that we `resolve` method is utilized in `.then` and `reject` in `.catch`.
## How to create a Promise?
To create a promise, you need to create an instance object using the Promise constructor function. The Promise constructor function takes in one parameter. That parameter is a function that defines when to resolve the new promise, and optionally when to reject it.
In promises, resolve is a function with an optional parameter representing the resolved value. Also, reject is a function with an optional parameter representing the reason why the promise failed.
## States of Promise
- pending: This is the default state of a defined promise
- fulfilled: This is the state of a successful promise
- rejected: This is the state of a failed promise
## Callback in Promises
To use a callback in Promise we need to use `.then` method. This method takes in two callback functions. The first function runs if the promise is resolved, while the second function runs if the promise is rejected.
## How Promises eliminate Callback hell
Promises are a good way to eleminate callback hell as they use `.then()` which returns a promise either fullfilled or rejected hence eliminating "Pyramid of Doom".
The above code will lead to Callback hell. Let's use Promise to resolve this issue.
Now here you can see that we no more have callback syntax and whenever a promise fails we have a rejected promise and we will stop here to check for errors.
## Handle Errors in Promise
To handle errors in Promises, use the `.catch()` method. If anything goes wrong with any of our promises, this method can catch the reason for that error.
## Handling multiple Promises at once
When we have multiple promises we can run all in parallel at once. The methods through which we can achieve this are -:
- `Promise.all()`
- `Promise.race()`
- `Promise.any()`
- `Promise.allSettled()`
**`Promise.all()`**
`Promise.all()` accepts an array of promises as an argument but returns a single promise as the output.
The single promise returns resolves with an array of values if all the promises in the input array are fulfilled.If at least one promise in the input array does not resolve, `Promise.all()` will return a rejected promise with a reason. The reason of rejection will be same as the promise that is rejected.
`Promise.all()` will run all the input promises before it returns a value. But it does not run the promises one after the other–instead it runs them at the same time.
This is why the total time it would take Promise.all() to return a value is roughly the time it would take the longest promise in the array to finish.
`**Promise.race()**`
`Promise.race()` returns a promise that resolves or rejects as soon as one of the promises in the iterable resolves or rejects.
Here as first promise is resolving fastly that is why first is printed.
If the promise with the shortest execution time happens to be rejected with a reason, `Promise.race()` returns a rejected promise and the reason why the fastest promise was rejected.
`**Promise.any()**`
`Promise.any()` accepts an array of Promises as an argument but returns a single Promise as the output. The single promise it returns is the first resolved promise in the input array. This method waits for any promise in the array to be resolved and would immediately return it as the output.
If none of the promises in the array are resolved, `Promise.any()` returns a rejected promise. This rejected promise contains a JavaScript array of reasons, where each reason corresponds with that of a promise from the input array.
**`Promise.allSettled()`**
`Promise.allSettled()` is used when we want to wait for all promises to complete regardless of whether they are fulfilled or rejected.
`Promise.allSettled()` is similar to `Promise.all()` in that all their input promises must settle before the promise they return has a settled state—fulfilled or rejected.
The difference is `Promise.all()` can only be successful if all the promises in the input are resolved, while `Promise.allSettled()` does not care about the status of the input promises.
So this was all about Promises. Now you have better understanding of Promises. In the next blog we will discuss about `Async/Await`. Till then stay connected and follow me.

It... | 0 | 2024-06-28T13:07:18 | https://dev.to/woovi/typesafe-http-request-in-node-3ld9 | typesafe, node, fetch | Ensuring that HTTP requests and responses are typesafe is crucial in modern web development. It prevents errors, improves code readability, and enhances developer productivity. This article explores how to implement typesafe HTTP requests in a Node.js environment using TypeScript and Fetch.
## Why Typesafe HTTP Requests?
Type safety in HTTP requests means defining and enforcing the structure of request payloads and response data. This practice provides several benefits:
Error Prevention: Catch type mismatches at compile-time rather than runtime.
Documentation: Type definitions serve as a form of documentation, making it clear what data structures are expected.
IntelliSense Support: Enhanced IDE support, offering autocompletion and inline documentation.
## Typesafe API pattern
Create one file per endpoint following the pattern <endpoint><method>, in my case, it will be `ipGet`.
Manually test the API using curl, postman, or pure node fetch API
For example before testing the API:
```ts
export const ipGet = async (): Promise<any> => {
const url = 'https://ifconfig.me/all.json';
const options = {
method: 'GET',
headers: {
Accept: 'application/json',
'Content-Type': 'application/json',
},
};
const response = await fetch(url, options);
return await response.json();
}
```
After testing the API you can get a few JSON response examples, so you can properly type the function.
This is the JSON of the API above
```json
{
"ip_addr": "2804:",
"remote_host": "unavailable",
"user_agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Safari/537.36",
"port": "45180",
"language": "en-US,en;q=0.9,pt;q=0.8,und;q=0.7,fr;q=0.6",
"method": "GET",
"encoding": "gzip, deflate, br, zstd",
"mime": "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.7",
"via": "1.1 google",
"forwarded": "2804:"
}
```
Go to [https://transform.tools/json-to-typescript](https://transform.tools/json-to-typescript) to transform the JSON into a Typescript type
The final code with the proper types would be:
```ts
export type Result = {
ip_addr: string
remote_host: string
user_agent: string
port: string
language: string
method: string
encoding: string
mime: string
via: string
forwarded: string
}
export const ipGet = async (): Promise<Result> => {
const url = 'https://ifconfig.me/all.json';
const options = {
method: 'GET',
headers: {
Accept: 'application/json',
'Content-Type': 'application/json',
},
};
const response = await fetch(url, options);
return await response.json();
}
```
You should also type the body of the request for POST and PUT.
Also, type the query string if any.
## In Conclusion
Following this simple structure, you are going to have a better DX to consume external HTTP requests in a typesafe way.
I would also save some examples of JSON in a `fixtures` directory to make it easy to write automated tests using `jest-fetch-mock`

**Introduction:
**
GraphQL is a query language for APIs. developed by Facebook (now Meta). It allows developers to get the data they need and only receive it in response to their queries. Magento 2 supports GraphQL to help you streamline your data processes.
Three main operations of GraphQL are in use:
queries (for reading and receiving information);
mutations (needed for taking actions, creating data, and changing information,insert,update,delete);
subscriptions (this operation isn’t available in Magento yet, but it provides the opportunity to get data from the server in real-time automatically after a while, for instance, for notification.
Queries:
For reading and receiving information.
Mutations:
It is an operation of GraphQL by which you can insert new data or modify the existing data.
Mutations requests should be in the POST method only. You can optionally send a GET query request in a URL.
Data with Mutations : Query is used to fetch data but there could be a need where a person needs to make changes in backend data. So to achieve this in GraphQL we use Mutations.
Mutation Operations :
– creating new data
– updating existing data
– deleting existing data
Why Use GraphQL:
Developers can request only the data they need, which results in smaller and more efficient data transfers. This is especially important for mobile and low-bandwidth devices.
It has a simple and intuitive syntax, making it easy for developers to learn and use. This simplicity reduces the learning curve and allows developers to focus on building their applications.
Developers can create custom GraphQL queries, mutations, and types, allowing them to extend the platform’s default schema and create custom functionality that meets their specific requirements.
It allows for optimized queries, which can significantly improve application performance. This is because it reduces the number of API requests required to fetch data.
Requirements for Run GraphQL in Magento 2:
You can check your GraphQL query response by installing chrome extension ChromeiQL Or Altair.
If you install a browser extension, make sure it can set request headers.
Access a graphQL Endpoint in Magento 2:
https://<magento2-server>/graphql
Add This Sample Graphql (Already Defined By Magento 2) In The Editor And Send A Request To Get Product Data And Test Whether The Graphql Environment Is Setup or Not.
#Request
{
products(
filter: { sku: { eq: "24-WB01" } }
) {
items {
name
sku
}
}
}
#Response:
{
"data": {
"products": {
"items": [
{
"name": "Voyage Yoga Bag",
"sku": "24-WB01"
}
]
}
}
}
Define GraphQL Schema (Create Custom GraphQL):
When making a GraphQL request in Magento, the request supports the HTTP GET and POST methods. Mutations requests should be in the POST method only. You can optionally send a GET query request in a URL.
For example, http://<host>/graphql?query=%7Bproducts sent a GET request with a query string in the URL.
First Create A Custom Module For Our Graphql And Make A Below Files At Specific Path
A GraphQL schema defines the types, queries, and mutations your API will support.
Next, create a file in app/code/Vendor/Module/etc/schema.graphls directory like in the example below. Note that the etc/schema.graphqls part is mandatory.
Schema.graphqls (Reference):
Defines the basic structure of queries and mutations.
Defines which attributes can be used for input and output in GraphQL queries and mutations.
Requests and responses contain separate lists of valid features.
Points to the resolvers that verify and process the input data and response.
Is the source for displaying the schema in a GraphQL browser.
Defines which objects are cached.
type Query {
myCustomQuery(input: MyCustomInput!): MyCustomOutput @resolver(class: "Vendor\\Module\\Model\\Resolver\\MyCustomQuery")
}
Now Create a Resolver Class For add custom logic and return output data at below path
Vendor/Module/Model/Resolver/MyCustomQuery.php
GraphQL Authorization (Reference):
Authorization tokens: Commerce generates a JSON Web Token (JWT), a set of cryptographically signed credentials. All calls that perform an action on behalf of a logged-in customer or admin provide an authorization token. Authorization tokens are stateless. Commerce does not need to know the state of a client to execute a request--the token contains all of the information needed for authorization and authentication.
Session cookies: A session cookie is information generated by Commerce that is stored in the client's browser. It contains details about the session, including the time period the user can access resources. Cookies are stateful, thereby increasing complexity and possibly latency.
Adobe recommends that you use authorization tokens instead of session cookies for GraphQL requests.
Adobe Commerce provides separate token services for customers and administrators. When you request a token from one of these services, the service returns a unique access token in exchange for the account's username and password.
GraphQL provides a mutation that returns a token on behalf of a logged-in customer, but you must use a REST call to fetch an admin token. Any time you make a GraphQL or REST call that requires a token, specify the HTTP Authorization request header and assign the value as Bearer <token>. Request headers provide an example.
Admin tokens:
In Adobe Commerce and Magento Open Source GraphQL, you specify an admin token only if you need to query products, categories, price rules, or other entities that are scheduled to be in a campaign (staged content). Staging is supported in Adobe Commerce only. See Staging queries for more information.
Adobe Commerce and Magento Open Source do not provide a GraphQL mutation that generates an admin token. You must use a REST endpoint such as POST /V1/tfa/provider/google/authenticate instead. Generate the admin token shows how to use this endpoint.
By default, an admin token is valid for 4 hours. You can change these values from Admin by selecting Stores > Settings > Configuration > Services > OAuth > Access Token Expiration > Admin Token Lifetime.
Customer tokens:
The generateCustomerToken mutation requires the customer email address and password in the payload, as shown in the following example.
By default, a customer token is valid for 1 hour. You can change these values from Admin by selecting Stores > Settings > Configuration > Services > OAuth > Access Token Expiration > Customer Token Lifetime.
#Request
mutation {
generateCustomerToken(email: "customer@example.com", password: "password") {
token
}
}
#Response
{
"data": {
"generateCustomerToken": {
"token": "hoyz7k697ubv5hcpq92yrtx39i7x10um"
}
}
}
generateCustomerTokenAsAdmin: for remote shopping assistant
#Request
mutation{
generateCustomerTokenAsAdmin(input: {
customer_email: "customer@gmail.com"
}){
customer_token
}
Set Header For Customer Authentication:
Key: Authorization
Value: Bearer {Token}
Query Example (Without Parameters):
Create a schema.graphql file under etc directory and put below code.
Vendor/Module/etc/schema.graphql
#Magento GraphQL Query Schema
type Query {
testcustomer: returnData
@resolver(class: "Dolphin\\Core\\Model\\Resolver\\Customer") @doc(description: "Returns information about a customer")
}
type returnData @doc(description: "Testcustomer defines the customer name and other details") {
entity_id: Int
firstname: String
lastname: String
email: String
}
Here we create a query with name testcustomer and assign a resolver class
Add description text using @doc(description:’abc’) & provide the fields for customers.
Now, Create a Resolver Class at Vendor/Module/Model/Resolver/Customer.php
Add Your Custom Logic and return data in this resolver class
<?php
namespace Dolphin\Core\Model\Resolver;
use Magento\Framework\GraphQl\Config\Element\Field;
use Magento\Framework\GraphQl\Query\ResolverInterface;
use Magento\Framework\GraphQl\Schema\Type\ResolveInfo;
class CustomData implements ResolverInterface
{
private $customDataProvider;
public function __construct(
\Dolphin\Core\Model\Resolver\DataProvider\CustomData $customDataProvider
) {
$this->customDataProvider = $customDataProvider;
}
public function resolve(
Field $field,
$context,
ResolveInfo $info,
array $value = null,
array $args = null
) {
$customData = $this->customDataProvider->getCustomData();
return $customData;
}
}
That’s It Now Open Your Editor And Run This GraphQl.
Note: Don’t Forget To Add Customer Token In Header Before Send A Request.
#Request
query {
testcustomer {
entity_id
firstname
lastname
email
}
}
Our Graphql Response Provides The Customer Data.
#Response
{
"data": {
"testcustomer": {
"entity_id": 208,
"firstname": "maulik",
"lastname": "maulik",
"email": "demo@gmail.com"
}
}
}
Mutation Example (With Parameters):
Vendor/Module/etc/schema.graphql
# mutation examples for update a record
type Mutation {
recordUpdate(input: editInput!): editOutput
@resolver(class: "Dolphin\\Core\\Model\\Resolver\\RecordUpdate")
@doc(description: "Data Update")
}
Here recordUpdate is the graphql schema which accepts input as a parameter.
(The exclamation(!) point indicates the value is non-nullable).
Additionally passed a resolver class which contains an operation logic of update record.
we pass the input fields like below into the editInput.
input editInput {
car_id: Int @doc(description: "Record Id")
manufacturer: String @doc(description: "The manufacturer Name")
model: String @doc(description: "The model")
}
We set some fields as an input which is used to get the user input & update the data.
editOutput is set the output data of graphql response.
type editOutput {
status: Boolean
message: String
}
Here status returns the value true/false And message shows a custom message to the user.
Create a Resolver File For Custom Logic and Set Return Data.
Make Sure the output data and structure are same as defined in the schema file else it will be returned null.
$recordUpdate = [];
$recordUpdate["status"] = $status;
$recordUpdate["message"] = $message;
return $recordUpdate;
Main function recordUpdate contains the output data with the key we passed on editOutput.
#Request
mutation {
recordUpdate(input:{ car_id: 10,manufacturer:"Honda",model:"RTX" }) {
status
message
}
}
#Response
{
"data": {
"recordUpdate": {
"status": true,
"message": "Data Update Successfully"
}
}
}
Magento 2 GraphQL Exception Handling:
Adobe Commerce and Magento Open Source provide the following exception classes in Magento\Framework\GraphQl\Exception\Class.
Exceptions:
CLASS
DESCRIPTION
GraphQlAlreadyExistsException
Thrown when data already exists
GraphQlAuthenticationException

Although men's fashion has evolved in many ways over the years, most guys continue to hold tight to their favorite pair of denim jeans. From how skinny to wear them, and the type of fit that is most flattering-how denim should look. Below are some tips to make sure you look perfect in your jeans.
Grow Your Denim Wardrobe Wisely
DENIMJANE STYLE TIPS, BUT... FIRST THINGS FIRST Before we get into style tips around this particular item of your wardrobe - let's talk about the main part itself. Take care to buy quality navy blue jeans when you purchase your denim. While inexpensive jeans may appear to be a more frugal choice, they won't last as long and you'll end up paying for them several times over.
Some of the Do's and Don'ts to look great
But what if you are now in possession of pants that might not be the most ideal but at least fit better than anything else? You want to make sure your jeans fit properly. They should be fitting tight but not too much or feeling loose. A good rule of thumb is to be able to easily slide two fingers between your waist and the top of your jeans. Secondly, your jeans should fall just above the ankle for a clean and current look.
For colors, dark wash denim is always a good shout to look smart. Some black jeans are also a good idea instead of classic blue ones. Light wash denim is great but stay away from looking too aged with punty holes or tears in your jeans.
How to Find the Best Jeans for Your Body Shape
All jeans are not created equal, as bodies differ. This tip is about shopping jeans: consider your body shape so the fit doesnt shade anything-appropriate across. Tall and slim guys tend to look good on straight or boot-cut leg high waisted bootcut jeans while the relaxed fit works better if you have larger thighs or a very muscular body.
Accessories to Levitate Your Style
Denim jeans can be either dressed up or down for the occasion. Wearing the right shoe is one way to really increase your denim game. Classic leather boots or tennis sneakers. Go for colorful loafers or dress shoes in textures, point it to a full high fashionable look.
Even accessories can add on to your denim look. Leather belt Leather watches A belt enhances your dress sense. Wear a denim hat and jacket for an individualistic edge if you are looking experimental.
In conclusion, every man should own black denim jeans. Always select jeans, that fit on your body shape and do not forget to add accessories in order you can play trends according to your personal style. Use these little hacks and you will never dress like a denim schlub again!

A pergunta que devemos nos fazer é: quanto conhecimento técnico e experiência acumulamos ao longo da jornada? Quanto evoluímos em liderança? Quanto conseguimos desapegar do nosso ego? Quanto crescemos profissionalmente em inteligência emocional?
Decisões estruturais não são soluções instantâneas e passos equivocados, devido à falta de experiência, reflexão e uma certa ingenuidade, podem afundar um projeto de software, gerando prejuízos bilionários.
Estude, avance e tenha em mente que o aprendizado é contínuo. Bom senso e humildade nunca fazem mal a ninguém.
Aprenda a reconhecer que também precisa de ajuda e o seu papel é conduzir uma jornada para a solução no lugar de fingir sabedoria e agir no modo "aliem" destruindo tudo ao redor.
Você precisa de uma consultoria especializada em estratégia de software para apoiar a modernização do seu software? Entre em contato. Até a próxima !!!

In today’s edition of writing about AWS services, we will be learning about NAT Gateways, what they are, how they work and how they enhance our cloud infrastructure. From NAT gateways we will finish it off by talking about VPC endpoints. Allons-y (FYI: that’s “let’s go” in French 😉)
## NAT Gateways
First and foremost, NAT stands for Network Address Translation. Let’s look at what NAT really is before moving on to NAT gateways proper. Network Address Translation is a process in which private IP addresses used on a network (usually a local area network) are translated into public IP addresses that can be used to access the internet.
To understand how NAT gateways work, we are going to use the example of a two-tier architecture with a web tier deployed on EC2 instance in a public subnet (a public subnet is a subnet that has a route to an Internet gateway on the route table associated with it) and an application tier deployed on EC2 instances in a private subnet ( a private subnet has no route to an internet gateway on its route table). With this architecture, the EC2 instances that make up the application tier are unable to access the internet because they the subnet in which they reside has no route to an IGW on its route table. How will the instances go about performing tasks like downloading update patches from the internet? The answer lies in using NAT gateways. For the application tier to have access to the internet, we need to provision a NAT gateway in the public subnet housing our web tier.
When an instance in the application tier wants to connect to the internet, it sends a request which carries information such as the IP address of the instance and the destination of the request to the NAT gateway in the public subnet. The NAT gateway then translates the private IP address of the instance to a public elastic IP address in its address pool and uses it to forward the request to the internet via the internet gateway. One important thing to note about NAT gateways is that, they won’t accept or allow any inbound communication initiated from the internet as it only allows outbound traffic originating from your VPC. This can significantly improve the security posture of your infrastructure.
NAT gateways are managed by AWS. To create a NAT gateway, all you have to do is specify the subnet it will reside in and then associate an Elastic IP address (EIP). AWS handles every other configuration for you.
## VPC Endpoints
VPC endpoints allow private access to an array of AWS services using the internal AWS network instead of having to go through the internet using public DNS endpoints. These endpoints enable you to connect to supported services without having to configure an IGW (Internet Gateway), NAT Gateway, a VPN, or a Direct Connect (DX) connection.
There are two types of VPC endpoints available on AWS. They are the Interface Endpoints and Gateway Endpoints
**Interface Endpoints** — They are fundamentally Elastic Network Interfaces (ENI) placed in a subnet where they act as a target for any traffic that is being sent to a supported service. To be able to connect to an interface endpoint to access a supported service, you use PrivateLink. PrivateLink provides a secure and private connection between VPCs, AWS services and on-premises applications through the internal AWS network.
To see the suite of services that can be accessed via interface endpoints, check out this [AWS documentation](https://docs.aws.amazon.com/vpc/latest/privatelink/aws-services-privatelink-support.html).
**Gateway Endpoints** — They are targets within your route table that enable you to access supported services thereby keeping traffic within the AWS network. At the time of writing, the only services supported by gateway endpoints are: S3 and DynamoDB. Be sure to check the appropriate AWS documentation for any addition to the list of services. One last thing to keep in mind about gateway endpoints is that they only work with IPv4
## Conclusion
Some say the mark of a good dancer is to know when to bow out of the stage. With that, we have officially reached the end of this article about VPC endpoints and NAT gateways. I will like to implore you to keep learning and getting better at using tools such as these for you don’t know when they will come in handy. That could be sooner rather than later. Thank you for riding with me to the very end. Best of luck in all your endeavors. | brandondamue |

I was also caught up in this scenario while working with on a Node project recently.
In this article, I want to outline how this tedious process could be made easier by using Nodemon to automatically execute this repetitive task while working on Node.js projects.
Before I proceed, I want to let you know about the HNG internship that gives early career professionals in tech a chance to work on real-world projects and gives them the experience of a real-time workspace remotely. Check it out here [HNG Internships](https://hng.tech/internship)
Moving forward, to work with Nodemon, I installed nodemon as a dependency in my project using npm
`npm install nodemon`
This takes a few seconds or minutes to execute depending on your bandwidth strength, and afterwards Nodemon is added as a dependency in the package.json file as seen below
```
{
"dependencies": {
"express": "^4.19.2",
"nodemon": "^3.1.0"
}
}
```
After this, I adjusted the value of the "start" property in my package.json file to "nodemon app.js" where "app.js" is the name of the entry file for my application and I save the changes. Code shown below
```
{
"scripts": {
"start": "nodemon app.js"
}
}
```
After applying these changes, my server application automatically restarts and adjust to any changes I make to the program logic and I don't need to manually do that again. Once I run "npm start" at the first instance, the nodemon dependency takes care of restarting my server after any change is made.
This is one of the techniques I have learnt while building my portfolio in backend development and I look forward to expanding my horizon in this field as I enroll for the HNG11 internship.
I believe the internship will give me an opportunity to apply the concepts and techniques I have learnt so far in a real-world setting and a chance to collaborate with other like-minded developers. If you are someone who also needs this type of experience, do well to check it out [here](https://hng.tech/premium) and learn more about the internship.
Thanks for reading this article, I hope you learnt something.

They are necessary to enable effective searching, retrieval, and data manipulation as well as meaningful data organization. Any developer that works with JavaScript—a language that is frequently used for web development—must understand sorting algorithms. With a particular emphasis on JavaScript implementation, this essay seeks to offer a thorough grasp of sorting algorithms.
Understanding Sorting Algorithms
Algorithms for sorting lists or arrays are processes that put the items in a specific order, usually lexicographical or numerical. Sorting algorithms come in a variety of forms, each having advantages and disadvantages. Selecting the appropriate algorithm for a given issue or dataset requires an understanding of these algorithms.
Why Sorting Algorithms Matter
Sorting is a common operation in programming. Whether you are managing databases, processing data for machine learning, or simply organizing a list of names, sorting algorithms come into play. Efficient sorting can save time and computational resources, making your applications faster and more responsive.
Categories of Sorting Algorithms
Sorting algorithms can be broadly classified into two categories:
Comparison-based Sorting Algorithms: These algorithms determine the order of elements by comparing them. Examples include Bubble Sort, Selection Sort, Insertion Sort, Merge Sort, Quick Sort, and Heap Sort.
Non-comparison-based Sorting Algorithms: These algorithms do not compare elements directly. Instead, they use other techniques to sort data. Examples include Counting Sort, Radix Sort, and Bucket Sort.
Common Sorting Algorithms in JavaScript
1- Bubble Sort
One of the most basic sorting algorithms is bubble sort. It runs over the list again and again, comparing next components and swapping them if they are out of order. Until the list is sorted, this procedure is repeated.
Implementation
```
function bubbleSort(arr) {
let n = arr.length;
for (let i = 0; i < n - 1; i++) {
for (let j = 0; j < n - 1 - i; j++) {
if (arr[j] > arr[j + 1]) {
// Swap arr[j] and arr[j + 1]
let temp = arr[j];
arr[j] = arr[j + 1];
arr[j + 1] = temp;
}
}
}
return arr;
}
let array = [64, 34, 25, 12, 22, 11, 90];
console.log(bubbleSort(array));
```
2- Selection Sort
Selection Sort divides the input list into two parts: the sorted part and the unsorted part. It repeatedly selects the smallest element from the unsorted part and moves it to the sorted part.
Implementation
```
function selectionSort(arr) {
let n = arr.length;
for (let i = 0; i < n - 1; i++) {
let minIndex = i;
for (let j = i + 1; j < n; j++) {
if (arr[j] < arr[minIndex]) {
minIndex = j;
}
}
if (minIndex !== i) {
// Swap arr[i] and arr[minIndex]
let temp = arr[i];
arr[i] = arr[minIndex];
arr[minIndex] = temp;
}
}
return arr;
}
let array2 = [64, 25, 12, 22, 11];
console.log(selectionSort(array2));
```
3- Insertion Sort
Insertion Sort builds the sorted array one item at a time. It picks the next element from the unsorted part and inserts it into its correct position in the sorted part.
Implementation
```
function insertionSort(arr) {
let n = arr.length;
for (let i = 1; i < n; i++) {
let key = arr[i];
let j = i - 1;
while (j >= 0 && arr[j] > key) {
arr[j + 1] = arr[j];
j--;
}
arr[j + 1] = key;
}
return arr;
}
let array3 = [12, 11, 13, 5, 6];
console.log(insertionSort(array3));
```
4- Merge Sort
Merge Sort is a divide-and-conquer algorithm. It divides the array into halves, sorts each half recursively, and then merges the sorted halves.
Implementation
```
function mergeSort(arr) {
if (arr.length <= 1) {
return arr;
}
const mid = Math.floor(arr.length / 2);
const left = arr.slice(0, mid);
const right = arr.slice(mid);
return merge(mergeSort(left), mergeSort(right));
}
function merge(left, right) {
let result = [];
let leftIndex = 0;
let rightIndex = 0;
while (leftIndex < left.length && rightIndex < right.length) {
if (left[leftIndex] < right[rightIndex]) {
result.push(left[leftIndex]);
leftIndex++;
} else {
result.push(right[rightIndex]);
rightIndex++;
}
}
return result.concat(left.slice(leftIndex)).concat(right.slice(rightIndex));
}
let array4 = [38, 27, 43, 3, 9, 82, 10];
console.log(mergeSort(array4));
```
5- Quick Sort
Another divide-and-conquer algorithm is Quick Sort. The array is divided into two parts, with items fewer than the pivot on one side and elements bigger than the pivot on the other, when a pivot element is chosen. The halves are then sorted recursively.
Implementation
```
function quickSort(arr) {
if (arr.length <= 1) {
return arr;
}
const pivot = arr[arr.length - 1];
const left = [];
const right = [];
for (let i = 0; i < arr.length - 1; i++) {
if (arr[i] < pivot) {
left.push(arr[i]);
} else {
right.push(arr[i]);
}
}
return [...quickSort(left), pivot, ...quickSort(right)];
}
let array5 = [10, 7, 8, 9, 1, 5];
console.log(quickSort(array5));
```
6- Heap Sort
Heap Sort is a comparison-based algorithm that uses a binary heap data structure. It divides the array into a sorted and an unsorted region and iteratively shrinks the unsorted region by extracting the largest element and moving it to the sorted region.
Implementation
```
function heapSort(arr) {
let n = arr.length;
// Build heap (rearrange array)
for (let i = Math.floor(n / 2) - 1; i >= 0; i--) {
heapify(arr, n, i);
}
// One by one extract an element from heap
for (let i = n - 1; i > 0; i--) {
// Move current root to end
let temp = arr[0];
arr[0] = arr[i];
arr[i] = temp;
// Call max heapify on the reduced heap
heapify(arr, i, 0);
}
return arr;
}
function heapify(arr, n, i) {
let largest = i;
let left = 2 * i + 1;
let right = 2 * i + 2;
if (left < n && arr[left] > arr[largest]) {
largest = left;
}
if (right < n && arr[right] > arr[largest]) {
largest = right;
}
if (largest !== i) {
let swap = arr[i];
arr[i] = arr[largest];
arr[largest] = swap;
heapify(arr, n, largest);
}
}
let array6 = [12, 11, 13, 5, 6, 7];
console.log(heapSort(array6));
```
7- Counting Sort
Counting Sort is a non-comparison-based sorting algorithm. It works by counting the number of occurrences of each distinct element in the array and then using this information to place the elements in the correct position.
Implementation
```
function countingSort(arr, maxValue) {
let count = new Array(maxValue + 1).fill(0);
let sortedArray = new Array(arr.length);
// Count the number of occurrences of each value
for (let i = 0; i < arr.length; i++) {
count[arr[i]]++;
}
// Modify count array such that each element at each index
// stores the sum of previous counts.
for (let i = 1; i <= maxValue; i++) {
count[i] += count[i - 1];
}
// Build the sorted array
for (let i = arr.length - 1; i >= 0; i--) {
sortedArray[count[arr[i]] - 1] = arr[i];
count[arr[i]]--;
}
return sortedArray;
}
let array7 = [4, 2, 2, 8, 3, 3, 1];
console.log(countingSort(array7, Math.max(...array7)));
```
8- Radix Sort
Radix Sort is another non-comparison-based algorithm. It processes each digit of the numbers and sorts them by individual digits, starting from the least significant digit to the most significant digit.
Implementation
```
function radixSort(arr) {
const max = Math.max(...arr);
let digit = 1;
while ((max / digit) >= 1) {
arr = countingSortByDigit(arr, digit);
digit *= 10;
}
return arr;
}
function countingSortByDigit(arr, digit) {
let count = new Array(10).fill(0);
let sortedArray = new Array(arr.length);
// Count the occurrences of each digit
for (let i = 0; i < arr.length; i++) {
let digitIndex = Math.floor((arr[i] / digit) % 10);
count[digitIndex]++;
}
// Transform count to position of each digit in sorted array
for (let i = 1; i < 10; i++) {
count[i] += count[i - 1];
}
// Build the sorted array
for (let i = arr.length - 1; i >= 0; i--) {
let digitIndex = Math.floor((arr[i] / digit) % 10);
sortedArray[count[digitIndex] - 1] = arr[i];
count[digitIndex]--;
}
return sortedArray;
}
let array8 = [170, 45, 75, 90, 802, 24, 2, 66];
console.log(radixSort(array8));
```
9- Bucket Sort
Bucket Sort works by distributing the elements of an array into a number of buckets. Each bucket is then sorted individually, either using a different sorting algorithm or by recursively applying the bucket sort.
Implementation
```
function bucketSort(arr, bucketSize = 5) {
if (arr.length === 0) {
return arr;
}
// Determine minimum and maximum values
let minValue = Math.min(...arr);
let maxValue = Math.max(...arr);
// Initialize buckets
let bucketCount = Math.floor((maxValue - minValue) / bucketSize) + 1;
let buckets = new Array(bucketCount).fill().map(() => []);
// Distribute input array values into buckets
for (let i = 0; i < arr.length; i++) {
let bucketIndex = Math.floor((arr[i] - minValue) / bucketSize);
buckets[bucketIndex].push(arr[i]);
}
// Sort buckets and concatenate results
arr = [];
for (let i = 0; i < buckets.length; i++) {
if (buckets[i].length > 0) {
insertionSort(buckets[i]); // Using insertion sort to sort individual buckets
arr = arr.concat(buckets[i]);
}
}
return arr;
}
let array9 = [29, 25, 3, 49, 9, 37, 21, 43];
console.log(bucketSort(array9));
```
Performance Analysis of Sorting Algorithms
Understanding the performance characteristics of different sorting algorithms is crucial for selecting the right one for your specific use case. The performance of sorting algorithms is typically measured in terms of time complexity and space complexity.
Time Complexity
Bubble Sort: O(n^2)
Selection Sort: O(n^2)
Insertion Sort: O(n^2), but O(n) when the array is nearly sorted
Merge Sort: O(n log n)
Quick Sort: O(n log n) on average, O(n^2) in the worst case
Heap Sort: O(n log n)
Counting Sort: O(n + k), where k is the range of the input
Radix Sort: O(nk), where k is the number of digits in the largest number
Bucket Sort: O(n + k), where k is the number of buckets
Space Complexity
Bubble Sort: O(1)
Selection Sort: O(1)
Insertion Sort: O(1)
Merge Sort: O(n)
Quick Sort: O(log n) (due to recursion)
Heap Sort: O(1)
Counting Sort: O(k)
Radix Sort: O(n + k)
Bucket Sort: O(n + k)
Stability of Sorting Algorithms
A sorting algorithm is stable if it maintains the relative order of records with equal keys (i.e., values). Stability is important in certain applications where the original order of equal elements needs to be preserved.
Stable Algorithms: Bubble Sort, Insertion Sort, Merge Sort, Counting Sort, Radix Sort, Bucket Sort
Unstable Algorithms: Selection Sort, Quick Sort, Heap Sort
Choosing the Right Sorting Algorithm
The choice of sorting algorithm depends on several factors, including the size of the input array, the range of input values, the need for stability, and the expected distribution of values.
Small Arrays
For small arrays, simple algorithms like Insertion Sort and Bubble Sort are often efficient due to their low overhead. Although they have a time complexity of O(n^2), their performance can be competitive with more complex algorithms for small datasets.
Large Arrays
For larger arrays, algorithms with better time complexity such as Merge Sort, Quick Sort, and Heap Sort are more appropriate. Merge Sort and Heap Sort offer guaranteed O(n log n) performance, while Quick Sort is typically faster in practice due to smaller constant factors, despite its worst-case O(n^2) time complexity.
Nearly Sorted Arrays
For arrays that are already nearly sorted, Insertion Sort can be particularly efficient, with a best-case time complexity of O(n).
Arrays with a Small Range of Values
When the range of values is small compared to the number of elements, Counting Sort and Radix Sort can be very efficient. Counting Sort is particularly useful when the range of the input values (k) is not significantly larger than the number of elements (n).
Arrays Requiring Stability
When stability is a requirement, choose from stable algorithms such as Merge Sort, Bubble Sort, and Insertion Sort. Radix Sort and Counting Sort are also stable and efficient for suitable datasets.

1,895,426 | Thread and Process | What is a Thread? Let's understand it. As we know, every computational device has a CPU,... | 0 | 2024-06-21T02:46:54 | https://dev.to/anupam_tarai_3250344e48cd/thread-53h1 | java, backend, programming | ## What is a Thread? Let's understand it.
As we know, every computational device has a CPU, in which all the operations or code executions are done. Some CPUs can execute only one process at a time, which is known as a single-core CPU. In modern computers, CPUs are multi-core. Multi-core CPUs allow the execution of multiple code blocks or multiple processes simultaneously.
> A thread is the smallest unit of a process. Mordern OS supports multithreading. It divides the process into smaller units/thread to execute multiple parts of the process concurrently, maximizing CPU utilization.
## Process VS Thread
## Process
- A process is a independent program in execution.
- It has it's own memory space, computer resource and execution context.
- Each process is operate/execute in isolation from other processes.
- Processes are managed by operating system and have their own address space, Which means they do not share memory directly with other processes.
## Thread
- A thread is a smaller unit of a process. It is sometimes referred to as a "lightweight process."
- Threads within the same process share the same memory space and resources. This allows for easier communication and data sharing between threads.
## Key Differences
**Memory and Resource Allocation**
- **Process:** Each process has its own memory space and resources. Inter-process communication (IPC) mechanisms like pipes, sockets, or shared memory are needed for processes to communicate.
- **Thread:**Threads within the same process share the same memory space and resources. This makes inter-thread communication faster and more efficient, as they can directly access shared data.
**Isolation:**
- **Process:** Processes are isolated from each other. A crash in one process typically does not affect others.
- **Thread:**Threads are not isolated. A crash in one thread can potentially bring down the entire process.
**Creation and Context Switching:**
- **Process:** Creating and context switching between processes is more expensive in terms of time and system resources because it involves switching the entire memory space and resources.
- **Thread:**Creating and context switching between threads is faster and more efficient since threads share the same memory space and resources.
**Communication:**
- **Process:**Processes require explicit IPC mechanisms to communicate, which can be complex and slower.
- **Thread:** Threads can communicate directly through shared memory, making inter-thread communication faster and simpler.
**Concurrency:**
- **Process:** Processes can run concurrently, but they require more system resources. Useful for running separate applications or tasks that do not need to share data.
- **Thread:** Threads allow for more fine-grained concurrency within a single application, enabling better utilization of multi-core processors for parallel tasks.
**Use Cases:**
- **Processes:**
Suitable for running independent applications.
Useful when tasks need strong isolation for security or stability.
Examples: Web servers, database servers, separate programs.
- **Threads:**
Ideal for tasks that require shared data or resources.
Useful for parallelism within a single application to improve performance.
Examples: Multi-threaded applications like web browsers, games, or parallel computations.
## Conclusion
> Processes offer strong isolation but are more resource-intensive and slower in context switching.
> Threads provide faster context switching and efficient communication but require careful management to avoid issues like race conditions and deadlocks due to shared resources.

1,903,972 | A Comparison between ReactJS and jQuery | Hi, welcome back to my blog, today I would like to compare two front end technologies developers use... | 0 | 2024-06-28T12:47:17 | https://dev.to/kansoldev/a-comparison-between-reactjs-and-jquery-4ei8 | javascript, frontend, webdev | Hi, welcome back to my blog, today I would like to compare two front end technologies developers use to build websites and web applications, React and jQuery. I am also currently learning TypeScript, and I am writing an article about how I used TypeScript to recreate a FEM project I built with JS, expect to see that soon.
## Introduction
ReactJS and jQuery are both popular front end tools for developing websites and web applications, but they have different purposes and excel in different scenarios. It's important to understand their differences and use cases so that you as a developer can choose the right tool for your projects. First of all, I know you will be like, what's even the point of learning jQuery in 2024?, before you attack me, you should know that as of August 2022, **77% of the 10 million most popular websites still use jQuery**, source from [Wikipedia](https://en.m.wikipedia.org/wiki/JQuery#:~:text=As%20of%20August%202022%2C%20jQuery,than%20any%20other%20JavaScript%20library). I think that says a lot about how jQuery is still very important in the web ecosystem, so it isn't going away anytime soon.
## What is ReactJS?
ReactJS is JavaScript library used to build complex user interfaces. It follows a component-based architecture that allows developers create reusable UI components. React has a large community with widespread corporate backing, which makes it an ideal choice for many large-scale applications. Here are some of the key features React provides
**Component-Based Architecture:**
In React, your entire UI is made up of components. Take for example your twitter feed, you have the like component, the tweet component that shows a users tweet, the retweet component, the trending component etc. With React, you can deal with this components individually, and combine them together to form your entire UI which promotes reusability and modularity.
**State Management**
With React, you don't have to directly manipulate your DOM like how it is done in jQuery with things like $("#test").text(""). React uses what is called a **state**. Whenever you update the state of a component, React essentially **reacts** to that change, and re-renders the component to reflect the change
**Virtual DOM:**
This is **the feature** that makes react stand out from libraries like jQuery. The Virtual DOM is a lightweight representation of the real DOM in memory. Whenever the state of your component updates, React uses it's diffing algorithm to figure out what has changed in the Virtual DOM, which in turn updates the real DOM. This helps to efficiently update and render only the necessary parts of your components
**JSX**
React uses a syntax known as JSX that allows you write HTML within your Javascript code with ease, no need for complex string interpolation. Although, developers who use other frameworks like Vue and Angular don't really like JSX that much, but I feel it's not so bad. Let me know what you think
Currently, I am in an internship called [HNG Internship](https://hng.tech/internship), and they also use React as part of their Tech Stack. This internship has produced industry proven developers, so if you are looking for professional developers, check out their hiring platform on their [website](https://hng.tech/hire). I am looking forward to learning more about React from this Internship, as well as make more friends and expand my network.
One thing to understand about React is that React is just the "View" in the MVC architecture. It isn't a full fledged framework like Angular, it's only responsibility is to render the view of your application, and ensure the view is in sync with the state.
**What is jQuery?**
jQuery is a lightweight, fast, and feature-rich JavaScript library. It simplifies HTML DOM manipulation, event handling, and animation, making it easier to use JavaScript. I got to enjoy writing JavaScript code more because of jQuery, it simplifies so many things that pure JS sometimes can overcomplicate. Some features that jQuery provides are :-
- Simplifying DOM manipulation. This isn't so straight forward with React
- It provides support for **AJAX (Asynchronous JavaScript and XML)**. You might argue most recent codebases don't use AJAX anymore, but there are still a lot of websites out there that use jQuery, and they need AJAX in other to do asynchronous operations
- Cross browser compatibility - jQuery ensures that code works across multiple browsers, without any errors
- It is useful for running simple scripts like form validation, simple animations like slide up, show and hide etc.
#### Key Differences
The key differences between React and jQuery is in the area of DOM manipulation. React uses a Virtual DOM, it doesn't manipulate the DOM directly, rather it only updates part of the DOM that changed, while with jQuery, you directly manipulate the DOM. React also offers better performance than jQuery thanks to how it handles DOM updates compared to jQuery's direct DOM manipulation. Since you can break your UI into several components with React, building complex applications becomes easier than if you were to try it with jQuery
#### Conclusion
Choosing between ReactJS and jQuery depends on your project's requirements. ReactJS is best suited for more complex, interactive, and scalable applications, while jQuery is still valuable for simpler and quick-fix tasks, you can also use it to build simple websites.

I've figured out my path. I know what I'll be doing for the rest of my working life. It's all settled now!" You know what happened after that.
The aviation industry collapsed in on its self, and thousands of people were laid off, including me. That left me stuck. I didn't have the kind of work experience to compete with the thousands of other people who had just been laid off too. I tried for a while, but without even a hint of success. The jobs that I got close to getting wouldn't even pay my bills. I had to have a serious reckoning with myself, to try to figure out what I wanted to do.
I decided I was tired of the ups and downs of manufacturing, and so knew I was going to go back to school, it was just a matter of deciding what to study. I went back and forth with myself, and what I wanted out of my new career. I thought about becoming an electrician, or an HVAC tech, which would provide the opportunity to start my own business. But i was exhausted by the schedule of manufacturing, days tend to start at 5 or 6 in the morning, and knew that construction would be the same.
So that left me to fall back on things I had experimented with in high school, IT and web design. So again I evaluated what i wanted out of my career, and settled on the main difference I felt between the two: the ability to work from home. I felt that web design, and later software engineering, offered more flexibility, and that was something that I liked a lot. As a massive plus it would bring me within a close proximity to a dream I had mostly given up on since starting a family: designing my own video games. And so I went looking for programs and ended up settling on flatiron. I am very excited to be on this journey, and see where the path will take me. | cwiverson | |

1,904,125 | Resolving Contract Disputes with Government Agencies | Unpacking the complexities of contract disputes with government agencies and how technology is paving the way for smoother resolutions. | 0 | 2024-06-28T12:40:51 | https://www.govcon.me/blog/resolving_contract_disputes_with_government_agencies | government, contracts, legaltech | ## Introduction
Welcome to the intricate world of contract disputes with government agencies! If you’re reading this, chances are you’ve either found yourself in a tug-of-war over a government contract or you’re trying to understand how to steer clear of such situations. Whichever the case, you’ve come to the right place. Today, we'll unpack this complex subject and explore how advanced technologies are revolutionizing dispute resolutions.
## The Nature of Government Contracts
Government contracts can be lucrative but come with a set of stipulations and regulations that differ substantially from private contracts. The stakes are high: government projects often involve substantial resources, tight deadlines, and rigorous standards.
### Why Disputes Arise
Disputes typically arise due to several reasons:
- **Compliance Issues**: Contractors might fail to meet the strict compliance requirements set by the government, leading to disagreements.
- **Scope Changes**: Misunderstandings over what the contract covers can cause frustrations and disputes.
- **Performance and Delivery**: Delays and performance issues can hinder project timelines, triggering disputes.
## Traditional Dispute Resolution Mechanisms
Traditionally, disputes with government agencies have been resolved through **litigation** or **arbitration**. However, both these methods come with their own set of challenges:
### Litigation
Litigation is often seen as a last resort due to its time-consuming and expensive nature. It involves:
1. **Filing a Claim**: The contractor or the agency files a claim to start the legal process.
2. **Discovery Phase**: Both parties present evidence, which can be a prolonged phase.
3. **Trial**: Finally, a court hearing is scheduled, and a judge or jury makes a decision.
### Arbitration
Arbitration, while faster and less public than litigation, can still be quite complex. It generally includes:
1. **Initiation**: Parties agree to resolve the dispute through arbitration rather than court.
2. **Selection of Arbitrator(s)**: Neutral arbitrator(s) are selected.
3. **Hearing**: Parties present their case to the arbitrator(s) who then provide a binding decision.
## The Rise of LegalTech in Dispute Resolution
Enter **LegalTech**—the game-changer! Legal technology is streamlining the dispute resolution process in unprecedented ways.
### Smart Contracts
Smart contracts powered by blockchain technology can drastically reduce misunderstandings and disputes. These self-executing contracts automate compliance and performance tracking. With predefined terms coded into the blockchain, they ensure that any deviation from the contract terms is flagged immediately.
### Artificial Intelligence (AI)
AI is transforming the legal landscape by:
- **Predictive Analytics**: AI can predict potential dispute areas by analyzing past contract performance and compliance data.
- **Document Review**: AI-powered tools can review and interpret large volumes of legal documents swiftly, identifying crucial details that might help in the dispute resolution process.
### Online Dispute Resolution (ODR)
ODR platforms offer a seamless and efficient alternative to traditional methods. Here’s how they work:
1. **Digital Submission**: Parties submit their disputes online.
2. **Automated Analysis**: Advanced algorithms analyze the case.
3. **Mediation and Resolution**: Qualified mediators facilitate online discussions, helping to reach an amicable resolution.
### E-Discovery Tools
E-Discovery tools automate the discovery phase by quickly sifting through electronic records. This significantly reduces the time required in traditional litigation and arbitration.
## Case Studies
Let's take a look at some real-world cases where technology facilitated smoother dispute resolutions:
1. **Case Study 1: Smart Contracts in Public Procurement**: A municipal government used smart contracts for a large infrastructure project, which drastically reduced compliance issues and disputes.
2. **Case Study 2: AI-Powered Dispute Resolution**: A federal agency employed AI to predict and resolve disputes in a major defense contract, saving months of potentially litigious back-and-forth.
## Conclusion
Resolving contract disputes with government agencies doesn’t have to be a convoluted, drawn-out affair. With the advent of LegalTech, we’re witnessing a revolution in how these disputes are managed and resolved. From predictive analytics to smart contracts, technology is paving the way for a more transparent, efficient, and amicable dispute resolution landscape.

- Managing column width according to data length.
- Making the table responsive for all screen sizes.
- Debugging a custom build table using the TanStack table.
- Comprehensive documents can make it difficult to find quick answers.
- The learning curve is steep.
### **Getting Started with TanStack Table**
Let's start with a simple example. I'll create a basic table using TanStack Table.
#### **Step 1: Install TanStack Table**
First, let's install TanStack Table and its peer dependencies.
```bash
npm install @tanstack/react-table
```
#### **Step 2: Set Up the Table**
I'll start by setting up our table component. For this example, I’ll use a simple dataset of users.
```jsx
import * as React from 'react';
import {
createColumnHelper,
flexRender,
getCoreRowModel,
useReactTable,
} from '@tanstack/react-table';
export type User = {
id: number;
name: string;
age: number;
email: string;
country: string;
subscription: string;
wallet_balance: number;
};
export const users: User[] = [
{
id: 1,
name: 'John Doe',
age: 35,
email: 'john.doe@example.com',
country: 'United States',
subscription: 'Premium',
wallet_balance: 150.25,
},
{
id: 2,
name: 'Alice Smith',
age: 28,
email: 'alice.smith@example.com',
country: 'Canada',
subscription: 'Basic',
wallet_balance: 50.75,
}
];
const columnHelper = createColumnHelper<User>();
const columns = [
columnHelper.accessor('name', {
header: () => 'Name',
cell: (info) => info.getValue(),
}),
columnHelper.accessor('age', {
header: () => 'Age',
cell: (info) => info.getValue(),
}),
columnHelper.accessor('email', {
header: () => 'Email',
cell: (info) => info.getValue(),
}),
columnHelper.accessor('country', {
header: () => 'Country',
}),
columnHelper.accessor('subscription', {
header: 'Subscription',
}),
columnHelper.accessor('wallet_balance', {
header: 'Wallet balance',
}),
];
const Table = () => {
const [data, _setData] = React.useState([...users]);
const table = useReactTable({
data,
columns,
getCoreRowModel: getCoreRowModel(),
});
return (
<table>
<thead>
{table.getHeaderGroups().map((headerGroup) => (
<tr key={headerGroup.id}>
{headerGroup.headers.map((header) => (
<th key={header.id}>
{header.isPlaceholder
? null
: flexRender(
header.column.columnDef.header,
header.getContext()
)}
</th>
))}
</tr>
))}
</thead>
<tbody>
{table.getRowModel().rows.map((row) => (
<tr key={row.id}>
{row.getVisibleCells().map((cell) => (
<td key={cell.id}>
{flexRender(cell.column.columnDef.cell, cell.getContext())}
</td>
))}
</tr>
))}
</tbody>
</table>
);
};
export default Table;
```
In the code above we have the users data to populate the table. I'm using the createColumnHelper function to create columnHelper which is then used to define an array of columns. These columns decide how data will appear in the table. It creates columns according to the header I have provided. In this case, it is "Name," "Age," "Email," etc. We can customize cell rendering behavior by providing the cell property. If it is not provided then it indicates that the default cell rendering behavior will be used.
The useReactTable hook is used to set up a table component with data and column configurations. This configuration decides how data will be rendered in the table. I'm using table.getHeaderGroups() and table.getRowModel().rows for generating the header and body of the table.
After some styling, the table would look like the below image:
#### **Step 3: Customize Accordingly**
You can now start customizing the table according to your needs. You can add search, sorting, pagination, or any other features. TanStack provides the hooks and ease to add all this functionality. You can refer to their official documentation [here](https://tanstack.com/table/latest/docs/introduction).
### **Conclusion**
TanStack Table could be a great option for your next project. Its headless UI makes design integration effortless, and its rich feature set makes it simple to create pagination, sorting, filtering, and other features. For further clarity, explore additional examples in the documentation.
