1,893,220 | Arrays in JavaScript: A Comprehensive Guide | Understanding Array Declaration and Accessing Elements, Array Methods: Adding and Removing Elements... | 26,790 | 2024-06-19T06:55:56 | https://dev.to/sadanandgadwal/arrays-in-javascript-a-comprehensive-guide-50ce | array, javascript, webdev, beginners | > Understanding Array Declaration and Accessing Elements, Array Methods: Adding and Removing Elements and Other Useful Array Methods, Iterating Over Arrays
Arrays are fundamental data structures in JavaScript, allowing us to store multiple values in a single variable. They are versatile and come with a variety of methods that make manipulating data efficient and straightforward. In this guide, we'll explore array basics, methods for adding and removing elements, and best practices for utilizing arrays effectively in your JavaScript code.
## Declaration and Accessing Elements
In JavaScript, you can declare an array using square brackets [] and populate it with elements separated by commas. Arrays can hold any type of data, including numbers, strings, objects, and even other arrays.
```
// Declaration of an array
let names = ['Raj', 'Shiva', 'Anand', 'Kumar'];
// Accessing elements using index
console.log(names[0]); // Output: 'Raj'
console.log(names[2]); // Output: 'Anand'
```
Arrays in JavaScript are zero-indexed, meaning the first element is accessed using index 0, the second with index 1, and so on.
**Array Methods: Adding and Removing Elements**
JavaScript arrays provide powerful methods for dynamically manipulating their contents:
- push: Adds one or more elements to the end of an array and returns the new length of the array.
```
names.push('Ajay');
console.log(names); // Output: ['Raj', 'Shiva', 'Anand', 'Kumar', 'Ajay']
```
- pop: Removes the last element from an array and returns that
```
element.
let lastName = names.pop();
console.log(lastName); // Output: 'Ajay'
console.log(names); // Output: ['Raj', 'Shiva', 'Anand', 'Kumar']
```
- shift: Removes the first element from an array and returns that element, shifting all other elements one position to the left.
```
let firstName = names.shift();
console.log(firstName); // Output: 'Raj'
```
- unshift: Adds one or more elements to the beginning of an array and returns the new length of the array.
```
names.unshift('Vivek');
console.log(names); // Output: ['Vivek', 'Shiva', 'Anand', 'Kumar']
```
## Useful Array Methods
- splice: Changes the contents of an array by removing or replacing existing elements and/or adding new elements.
```
names.splice(2, 0, 'Rahul'); // Insert 'Rahul' at index 2
console.log(names); // Output: ['Vivek', 'Shiva', 'Rahul', 'Anand', 'Kumar']
```
- slice: Returns a shallow copy of a portion of an array into a new array object selected from start to end (end not included).
```
let selectedNames = names.slice(1, 4); // Returns elements at index 1, 2, and 3
console.log(selectedNames); // Output: ['Shiva', 'Rahul', 'Anand']
```
- concat: Combines two or more arrays and returns a new array.
```
let moreNames = ['Suresh', 'Deepak'];
let allNames = names.concat(moreNames);
console.log(allNames);
```
**Iterating Over Arrays**
You can iterate over arrays using loops or array methods like
```
forEach, map, filter, and reduce. Here's an example using forEach:
names.forEach(function(name, index) {
console.log(`Name at index ${index}: ${name}`);
});
```
**> Certainly! coding problems, along with their solutions in JavaScript. **
**Problem 1: Find the Largest Number in an Array**
Problem Statement: Write a function that takes an array of numbers as input and returns the largest number in the array.
Example: Input: [3, 9, 1, 25, 6] Output: 25
Solution:
```
function findLargestNumber(arr) {
if (arr.length === 0) {
return null; // Return null for empty array or handle accordingly
}
let max = arr[0]; // Assume the first element is the largest initially
for (let i = 1; i < arr.length; i++) {
if (arr[i] > max) {
max = arr[i]; // Update max if current element is larger
}
}
return max;
}
// Example usage:
let numbers = [3, 9, 1, 25, 6];
console.log("Largest number:", findLargestNumber(numbers)); // Output: 25
or
//one-liner version
let findLargestNumberOneliner = arr => arr.length === 0 ? null : arr.reduce((max, current) => current >= max ? current : max, arr[0]);
let numbers1 = [3, 9, 1, 25, 6];
console.log("Largest number:", findLargestNumberOneliner(numbers1));
```
- This one-liner version achieves the same functionality as the original function:
- It uses Array.prototype.reduce to iterate over the array and find the maximum number.
- The initial value of max is set to arr[0], assuming the array is not empty (handled by the ternary operator arr.length === 0 ? null : ...).
- It compares each element current with max and updates max if current is larger.
**Problem 2: Reverse a String**
Problem Statement: Write a function that takes a string as input and returns the string reversed.
Example: Input: "hello" Output: "olleh"
Solution:
```
function reverseString(str) {
return str.split('').reverse().join('');
}
// Example
let str = "hello";
console.log("Reversed string:", reverseString(str));
// Output: "olleh"
```
Explanation:
- split('') : The split('') method splits the string str into an array of characters. If you pass an empty string '' as the delimiter, each character of the string becomes an element in the array.
- For str = "hello", str.split('') returns ['h', 'e', 'l', 'l', 'o'].
- reverse(): The reverse() method reverses the elements of the array.
- After ['h', 'e', 'l', 'l', 'o'].reverse(), the array becomes ['o', 'l', 'l', 'e', 'h'].
- join(''): The join('') method joins all elements of the array into a string.
- ['o', 'l', 'l', 'e', 'h'].join('') returns "olleh".
- Return Statement: Finally, return str.split('').reverse().join(''); returns the reversed string "olleh".
**Problem 3: Remove Duplicates from an Array**
Problem Statement: Write a function that takes an array of numbers or strings and returns a new array with duplicates removed.
Example: Input: [1, 3, 5, 3, 7, 1, 9, 5] Output: [1, 3, 5, 7, 9]
Solution:
```
function removeDuplicates(arr) {
let uniqueArray = [];
for (let i = 0; i < arr.length; i++) {
if (uniqueArray.indexOf(arr[i]) === -1) {
uniqueArray.push(arr[i]);
}
}
return uniqueArray;
}
// Example usage:
let numbersWithDuplicates = [1, 3, 5, 3, 7, 1, 9, 5];
let uniqueNumbers = removeDuplicates(numbersWithDuplicates);
console.log("Array with duplicates removed:", uniqueNumbers); // Output: [1, 3, 5, 7, 9]
or
//one-liner version
let removeDuplicatesOneliner = arr => [...new Set(arr)];
let numbersWithDuplicatesOneliner = [1, 3, 5, 3, 7, 1, 9, 5];
let uniqueNumbersOneliner = removeDuplicatesOneliner(numbersWithDuplicatesOneliner);
console.log("Array with duplicates removed:", uniqueNumbersOneliner);
```
- This one-liner version achieves the same functionality as the original function:
- Arrow Function: removeDuplicates is now written as an arrow function, which simplifies its syntax.
- Set Object: [...new Set(arr)] utilizes the Set object in JavaScript, which automatically removes duplicate values from an array.
- new Set(arr): Creates a Set object from the array arr, removing duplicates.
- [...new Set(arr)]: Converts the Set object back to an array.
- Example Usage: The function removeDuplicates is applied to numbersWithDuplicates, resulting in uniqueNumbers, which contains only the unique values from numbersWithDuplicates.
**Explanation for above questions:**
1. Find the Largest Number in an Array: Iterate through the array, keeping track of the maximum number encountered.
2. Reverse a String: Convert the string to an array of characters, reverse the array, and then join the characters back into a string.
3. Remove Duplicates from an Array: Use an auxiliary array (uniqueArray) to keep track of unique elements encountered so far. Check each element against uniqueArray and add it if it doesn't already exist.
These problems are common in interviews because they test basic understanding of algorithms (like searching and sorting) and manipulation of data structures (like arrays and strings). Practice these types of problems to improve your problem-solving skills and familiarity with JavaScript syntax and built-in functions.
**Conclusion**
Arrays in JavaScript are powerful and flexible, offering a wide range of methods for manipulating data efficiently. Understanding how to declare, access, and use array methods effectively will enhance your ability to work with collections of data in your JavaScript applications. Experiment with these methods and incorporate them into your projects to become proficient in handling arrays. Happy coding!

[GROWI](https://growi.org/), an open-source in-house wiki, has a public REST API. To make this API easier to use, we are developing a TypeScript/JavaScript SDK. It is still in progress, but we will gradually add more functions.
This article will explain how to perform CRUD (Create, Read, Update, Delete) operations on pages.
## Notes
This is a community SDK. Please refrain from contacting the official.
## Source code
The source code of GROWI TypeScript/JavaScript SDK is available on GitHub. The license is MIT.
[goofmint/growi-sdk-alpha](https://github.com/goofmint/growi-sdk-alpha)
## Installation
Installation is done via npm/yarn.
```bash
$ npm install @goofmint/growi-js
# or
$ yarn add @goofmint/growi-js
```
## Usage
First, import the SDK.
```javascript
const { GROWI } = require('@goofmint/growi-js');
// or
import { GROWI } from '@goofmint/growi-js';
```
Then, initialize it. At this point, we specify the API token for GROWI.
```javascript
const growi = new GROWI({ apiToken: 'your-api-token' });
```
In addition, the following parameters are provided.
- `url` : URL of GROWI. The default is `http://localhost:3000`.
- `path` : specifies the page path of GROWI. The default is '' . Specify when installing in a subdirectory.
## Get page
Currently, getting pages from the root is supported. The return value is a `Page` object.
```javascript
const page = await growi.root();
```
The page body is retrieved using the `contents` method.
```javascript
const contents = await page.contents();
```
## Get child pages
Use the `children` method to retrieve child pages. This is an array of `Page`.
```javascript
const children = await page.children();
```
## Update body text
To update the body, apply the body to the `contents` method. Then, call the `save` method.
```javascript
page.contents('new body');
await page.save();
```
## Create a new page
To create a new page, use the `create` method.
```javascript
const newPage = await growi.create({name: 'new page'});
```
When created, the `body` parameter can be used to specify the page's body, and the `grant` parameter can be used to specify the scope of the publication.
```javascript
const newPage = await page.create({ name, grant: growi.Page.Grant.public });
```
## Remove a page
Use the `remove` method to remove a page.
```javascript
await page.remove();
```
The optional parameter `isCompletely` will physically remove the page. If `isRecursively`, child pages are also removed recursively.
## Summary
As an in-house wiki, GROWI will likely need data linkage with in-house systems. Please use the Node.js SDK to operate GROWI from your system.

In the last post we have talked about about Math library, RegEx and destructuring in JavaScript. In this post we are going to know about hoisting and interpolation in JavaScript.
So let's get started🔥
## Hoisting in JavaScript
Hoisting is a JavaScript mechanism where variables and function declarations are moved to the top of their containing scope during the compilation phase. This means that you can use variables and functions before you declare them in your code.
So here you can see that we can use `x` before it is declared this is what hoisting is.
**Hoisting of variables**
For variables declared using var, the declaration is hoisted to the top, but the initialization stays in place. Until the code execution reaches the line where the variable is initialized, it will have a value of `undefined`.
For variables declared using `let` and `const`, the declarations are also hoisted, but they are not initialized. Accessing them before their declaration results in a `ReferenceError`.
**Function Hoisting**
Function declarations are hoisted entirely, including their definitions. This means you can call a function before you declare it in the code.
However, function expressions (both regular and arrow functions) are treated like variables and only the variable declaration is hoisted, not the assignment.
## Interpolation in JavaScript
String interpolation is a great programming language feature that allows injecting variables, function calls, and arithmetic expressions directly into a string. String interpolation was absent in JavaScript before ES6.
Let's see how string concatenation works-:
Here you can see that we can easily use variables in string by just concatenating them to the string. But this becomes very complex and tedious with large strings. This is why interpolation that is use of ``(backticks) and $ {expression} were introduced in ES6.
Let's see the above code using interpolation-:
You can see that now we don't have to worry with adding whitespaces like `" "` and complex concatenation.
Interpolation is just use of JavaScript expression in string.
You can see that how we are easily using ternary expression in string using interpolation.
So this was it for this blog. I hope you have understood it well. In the later blogs we are going to see some more important concepts of JavaScript. Till then stay connected and don't forget to follow me.
Thankyou 🩵

It’s been a very long time since I last posted! However, I came across something so fascinating that I couldn’t resist posting about it. “What is it?” You may ask, to which my response will be “read the title of this post.”
I was perusing through Eventbrite looking for tech meetups and networking events when I came across Signals and Pixels Art & Tech Meetup held at Hairpin Art Studio in the Avondale neighborhood of Chicago. The most interesting part about this meetup was something called “creative coding.” As a self-proclaimed music enthusiast and crochet hobbyist, I saw both art, music, and programming come together in the most extraordinary way.
**Today I learned** about a very interesting programming language called Max, also referred to as Max/MSP or Max/MSP/Jitter. Max is a visual block-based audio and multimedia programming language.
When I saw it, my first reaction was, "Scratch, is that you?” Scratch is also a visual block-based programming language; however, it isn’t strictly for music or multimedia.
Then I heard an ethereal sound that I titled “Quiescence Harmony,” created by a developer who wanted to listen to calming music while coding. Instead of finding music to listen to on Spotify, YouTube, SoundCloud, or Apple Music, he decided to create the music himself using the Max programming language. With some experimentation, or rather, when the developer added a block of code, to my dismay, the harmony quickly turned into a cacophony of sounds. It’s okay! He quickly rectified it by getting rid of that block of code and adding some additional blocks that produced a serene sound that complemented the original “Quiescence Harmony.” That wasn’t the end of it. There were visuals that accompanied and responded to the music!
If you’re a developer who loves music and art, Max might be the programming language for you. | prettyalana |

1,893,197 | HOT Protocol Project: Innovations, Goals, and Team | HOT Protocol Project: Innovations, Goals, and Team HOT Protocol is an ambitious cryptocurrency... | 0 | 2024-06-19T06:32:47 | https://dev.to/bin_bin_a2cdc79c28398885b/hot-protocol-project-innovations-goals-and-team-138l | cryptocurrency, hotdao, mining, review | HOT Protocol Project: Innovations, Goals, and Team
HOT Protocol is an ambitious cryptocurrency project built on the NEAR blockchain, offering innovative solutions in digital assets and finance. Let’s explore what this project entails, its goals, the team behind it, and the latest developments.
What is HOT Protocol?
HOT Protocol is a decentralized platform that allows users to create, store, and trade digital assets, including NFTs. The project combines high security standards with a user-friendly interface, making it accessible even for newcomers to the cryptocurrency space.
Key features of HOT Protocol:
- MPC Wallet: A wallet that splits the private key into multiple parts for enhanced security.
- HOT Accounts: Accounts with distributed private keys, allowing for passphrase changes and enabling two-factor authentication (2FA).
- Cross-Chain Gas: Capability to conduct transactions on any network using HOT tokens as gas fees.
Project Goals
Expanding User Capabilities:
- Support for EVM-compatible networks: such as Ethereum, BASE, Arbitrum, and Optimism.
- Integration with other blockchain platforms: including Solana, TON, and Bitcoin.
Security and Staking:
- Staking mechanisms: for HOT tokens, allowing users to earn rewards for holding coins.
- New security features: Implementation of two-factor authentication (2FA) and passphrase change options.
Trading on WhiteBit:
HOT is already traded on WhiteBit, with a daily trading volume of around $2 million. Compared to TWT futures on Binance, which have a volume of $5 million per day, HOT on Binance could potentially have a much higher trading volume.
Forecast and Potential of HOT
- Market Capitalization: It is predicted that HOT could reach a market cap of $1 billion. With 100 million tokens in circulation, the price could exceed $10 per token.
- NEAR and HOT: NEAR Protocol has announced Chain Abstraction, which could significantly change the Web3 landscape, impacting HOT's future development.
Cross-Network Gas Relay:
- Transaction Facilitation: Enabling transactions across networks and HOT token transfers for greater flexibility and user convenience.
Team and Founders
HOT Protocol is developed by a team of experienced blockchain developers and enthusiasts. Key team members include:
- Petr Volnov: One of the founders and lead developers with significant experience in Python and Solidity. He is also the founder of HERE Wallet for NEAR and actively contributes to the NEAR ecosystem through GitHub and social media.
Latest Developments
Recently, HOT Protocol has achieved several significant milestones:
- Support for new blockchains: The project is actively integrating with new blockchain networks, significantly expanding its capabilities.
- Launch of new security features: Introduction of two-factor authentication and passphrase change options to enhance user security.
- Developer interviews: Petr Volnov and other team members regularly participate in interviews, discussing new achievements and future plans, providing insights into the project's direction.
HOT Mining
HOT mining began in February 2024 and will continue until September-October 2024, providing an opportunity for users to participate and earn HOT tokens.
Addressing HOT Wallet's Drawbacks
Disclaimer: Not participating in the HOT Wallet project may be a significant oversight for many, as the project is worth every minute of your time and more. For example, the project is seven times older than NOTcoin and, unlike other projects, has ready solutions for 90% of potential issues. There are no other contenders for the "throne."
Today’s discussion focuses on analyzing HOT Wallet — one of the most talked-about topics in the crypto community. While many praise its innovations and capabilities, it’s important to consider some drawbacks that could impact your experience with the platform and its future.
Weak Marketing: Despite being a pioneer, HOT's audience is smaller than some weaker projects. This may indicate a less active marketing strategy or a deliberate choice of a higher-quality, but smaller audience.
New User Onboarding: Although the onboarding is eased with quests that earn users 6+ HOT, many new users still struggle to understand how to use the wallet. More guides and instructions could significantly ease the entry process.
Reward System: The philosophy of equal chances in claiming rewards is good in theory but causes dissatisfaction in practice among users who don't understand why some succeed in claiming rewards while others do not. A model like Binance NFT’s could reduce negative feedback.
Token Burning: While the burning mechanism is effective, reducing the number of available tokens is always a plus. It might be worth reconsidering the commission sizes for village-to-village transfers. Migration won’t decrease, but additional tens of thousands of HOT will burn forever.
Lack of Self-Promotion: It’s important not only to perform well but also to communicate achievements. The HOT team should more actively share successes to build trust and expand their audience. While avoiding excessive self-praise like the NOT team, it's necessary to highlight their achievements frequently.
Limited Interactivity in HOT Wallet: Despite all wallet products being free, HOT Wallet faces a lack of interactivity. Most actions within the wallet are about changing, transferring, etc., requiring a certain balance. While this is a good audience filter, it might be unwise to dismiss potential users aged 14-18 and others who currently can't or don't want to fund their wallets. Many of them are well-versed in cryptocurrencies but can't maintain an active balance. Providing these users a chance to explore HOT Wallet products could be an investment in the future, yielding dividends in 2-5 years.
Conclusion
HOT Wallet offers many opportunities and is the best product launched on Telegram, but like any innovative project, it faces several issues that need to be addressed on the go. Understanding these nuances will help you use this tool most effectively and avoid potential disappointments. You didn't see a point about listing dates here. Why? I have repeatedly written that the end-user benefits from postponing the listing, allowing the team to prepare a more refined product and secure new important partnerships, which will also affect the HOT token price.

[GROWI](https://growi.org/en/), an open-source in-house wiki, provides a plug-in feature. You can use it to display your own data or customize the display.
This is the first time I have developed a GROWI plugin, and we will explain the procedure.
## Plug-in developed
I developed [GROWI Plug-in to embed YouTube URL](https://github.com/goofmint/growi-plugin-embed-youtube). When you paste a YouTube URL into a GROWI page, the URL will be embedded in the GROWI page.
If you do not want to embed the link, please use the youtu.be domain.
```markdown
// will be embedded
https://www.youtube.com/watch?v=XXXXXXXXXXX
// will not be embedded
https://youtu.be/XXXXXXXXXXX
// the following will not be embedded
If you would like to see the video, please visit [this link](https://youtu.be/XXXXXXXXXXX).
```
## Plugin Development
When developing the plugin, I used [the template introduced recently](https://qiita.com/goofmint/items/497ea7dd722528cfa0cb) as a base.
[goofmint/growi-plugin-script-template: this is a template for creating a GROWI script plugin.](https://github.com/goofmint/growi-plugin- script-template)
### Rename
Rename the plugin.
```json
{
"name": "growi-plugin-youtube-embed", // change
"version": "1.0.0",.
"description": "GROWI plugin for embedding YouTube videos", // Change
:: }
}
```
Install the libraries needed for plugin development.
```bash
$ yarn
```
### Rename the files
Rename `src/Hello.tsx` and `src/Hello.css` to `src/EmbedYouTube.tsx` and `src/EmbedYouTube.css`.
### Edit src/EmbedYouTube.tsx
Depending on the content of the link, we determine whether it is a normal link or an embedded link.
```tsx
import innerText from 'react-innertext';.
import '. /EmbedYouTube.css';
const getYouTubeId = (href: string): string | null => {
const url = new URL(href);
const videoId = url.searchParams.get('v');
if (videoId) return videoId;
return null; }
};
export const EmbedYouTube = (A: React.FunctionComponent<any>): React.FunctionComponent<any> => {
return ({ children, href, . .props }) => {
const videoId = getYouTubeId(href);
// normal link
if (!videoId) {
return (
<>
<A {. .props}>{children}</A>
</>
);
}
// convert to embedded display
return (
<div className="youtube">
<iframe
width="560"
height="315"
src={`https://www.youtube.com/embed/${videoId}`}
title="YouTube video player"
allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share"
referrerPolicy="strict-origin-when-cross-origin"
allowFullScreen
></iframe>
</div>
);
};
};
```
### Edit src/EmbedYouTube.css
Write the CSS to make the video responsive.
```css
.youtube {
width: 100%;
aspect-ratio: 16 / 9;
}
.youtube iframe {
width: 100%;
height: 100%; }
}
```
### Editing client-entry.tsx
Edit `client-entry.tsx` to override the' a' tag's processing. This will send all `a` tag-related processing to `EmbedYouTube`.
```ts
const activate = (): void => {
if (growiFacade == null || growiFacade.markdownRenderer == null) {
return;
}
const { optionsGenerators } = growiFacade.markdownRenderer;
optionsGenerators.customGenerateViewOptions = (. .args) => {
const options = optionsGenerators.generateViewOptions(. .args);
const A = options.components.a;
// replace
options.components.a = EmbedYouTube(A); // overwrite processing
return options; }
}; }
};
```
## About the code
This plugin is available when you use it. Please specify `https://github.com/goofmint/growi-plugin-embed-youtube` in the GROWI plugin management.
[goofmint/growi-plugin-embed-youtube: this is a GROWI plugin to change YouTube URL to embed](https://github.com/goofmint/growi-plugin-embed-youtube)
## Summary
The GROWI plugin makes it very easy to customize the display content. This time, it is the `a` tag, but you can also customize other tags, such as the `img` tag and the `table` tag.
Please develop a plugin and make GROWI more useful!

1,893,194 | Death Calculator | Overview of How the Death Calculator Works The Death Calculator is designed to estimate life... | 0 | 2024-06-19T06:30:21 | https://dev.to/vinkalprajapati/death-calculator-5f3 | codepen, deathcalculator, vinkal041, vinkalprajapati |
{% codepen https://codepen.io/vinkalPrajapati/pen/YzbeaPP %}
Overview of How the Death Calculator Works
The Death Calculator is designed to estimate life expectancy based on user-inputted factors and provide interactive visualizations and information about remaining lifespan.
Form Submission Handling:
When the user submits the form with their name, date of birth (DOB), gender, lifestyle habits (smoking, exercise, diet, alcohol consumption), and living area, the JavaScript code captures these inputs.
Calculation of Life Expectancy:
Using the moment.js library, the calculator computes the user's current age and total days lived since their DOB.
Factors such as gender, smoking habits, exercise frequency, diet quality, alcohol consumption, and living area are taken into account to adjust the baseline life expectancy (set at 80 years in this example).
Displaying Results:
The calculated life expectancy, along with various informative details, is displayed dynamically in the user interface.
Information includes the user's birth date, current age, days lived, approximate seconds lived, and years remaining based on adjusted life expectancy.
Motivational and inspirational quotes are also included to encourage the user.
Visual Representation (Chart.js):
A doughnut chart is generated using Chart.js to visually represent the user's lifespan.
The chart displays two segments: years lived and years remaining, with corresponding colors and labels.
It provides a quick and intuitive visualization of how much of life has been lived and how much remains.
Real-Time Countdown:
A countdown timer dynamically calculates and displays the remaining years, days, hours, minutes, and seconds until the estimated death date.
It updates every second to reflect real-time changes based on the user's current age and adjusted life expectancy.
Speech Synthesis:
A feature allows the calculator to speak the calculated results aloud using the browser's SpeechSynthesis API.
When initiated, the calculator reads out details like name, birth date, age, days lived, remaining years, and motivational quotes.
A "Stop Speaking" button allows users to interrupt or stop the speech synthesis at any time.
User Experience and Accessibility:
The calculator enhances user experience with interactive elements like dynamic charts, real-time countdowns, and spoken output.
It promotes accessibility through speech synthesis, making the information accessible to users with visual impairments or those who prefer auditory feedback.
Overall, the Death Calculator provides a personalized and interactive experience by combining data analysis, visualization, real-time updates, and accessibility features to engage users in understanding and reflecting on their estimated lifespan based on various lifestyle choices and demographic factors. | vinkalprajapati |
1,893,193 | Add an alarm clock to the trading strategy | Traders who design trading strategies often ask me how to design timing functions for strategies so... | 0 | 2024-06-19T06:29:59 | https://dev.to/fmzquant/add-an-alarm-clock-to-the-trading-strategy-34of | trading, strategy, cryptocurrency, fmzquant | Traders who design trading strategies often ask me how to design timing functions for strategies so that strategies can handle certain tasks at specified times. For example, some intraday strategies need to close positions before the first section end in a trading day. How to design such requirements in the trading strategy? A strategy may use a lot of time control. In this way, we can encapsulate the time control function to minimize the coupling between the time control code and the strategy, so that the time control module can be reused and is concise in use.
## Design an "alarm clock"
```
// triggerTime: 14:58:00
function CreateAlarmClock(triggerHour, triggerMinute) {
var self = {} // constructed object
// Set members and functions to the constructed object below
self.isTrigger = false // Has it been triggered that day
self.triggerHour = triggerHour // The planned trigger hour
self.triggerMinute = triggerMinute // The planned trigger minute
self.nowDay = new Date().getDay() // what day is the current time
self.Check = function() { // Check function, check trigger, return true when triggered, return false if not triggered
var t = new Date() // Get the current time object
var hour = t.getHours() // Get the current decimal: 0~23
var minute = t.getMinutes() // Get the current minute: 0~59
var day = t.getDay() // Get the current number of days
if (day != self.nowDay) { // Judge, if the current day is not equal to the day of the record, reset the trigger flag as not triggered and update the number of days for the record
self.isTrigger = false
self.nowDay = day
}
if (self.isTrigger == false && hour == self.triggerHour && minute >= self.triggerMinute) {
// Determine whether the time is triggered, if it meets the conditions, set the flag isTrigger to true to indicate that it has been triggered
self.isTrigger = true
return true
}
return false // does not meet the trigger condition, that is, it is not triggered
}
return self // return the constructed object
}
```
We have designed and implemented a function to create an alarm clock object (can be understood as a constructor), and other languages can directly design an alarm clock class (for example, using Python, we will implement one in Python later).
Design the function to construct the "alarm clock" object, and only need one line of code to create an "alarm clock" object in use.
```
var t = CreateAlarmClock(14, 58)
```
For example, create an object t and trigger it at 14:58 every day.
You can create another object t1, which is triggered every day at 9:00.
```
var t1 = CreateAlarmClock(9, 0)
```
## Test strategy
We write a test strategy. The strategy uses the simplest moving average system. The strategy is just for testing and does not care about the profit.
The strategy plan is to open a position (long, short, no trade) based on the daily moving average golden cross and dead cross when the market opens at 9:00 every day, and close the position at 14:58 in the afternoon (close at 15:00).
```
function CreateAlarmClock(triggerHour, triggerMinute) {
var self = {} // constructed object
// Set members and functions to the constructed object below
self.isTrigger = false // Has it been triggered that day
self.triggerHour = triggerHour // The planned trigger hour
self.triggerMinute = triggerMinute // The planned trigger minute
self.nowDay = new Date().getDay() // what day is the current time
self.Check = function() {// Check function, check trigger, return true when triggered, return false if not triggered
var t = new Date() // Get the current time object
var hour = t.getHours() // Get the current decimal: 0~23
var minute = t.getMinutes() // Get the current minute: 0~59
var day = t.getDay() // Get the current number of days
if (day != self.nowDay) {// Judge, if the current day is not equal to the day of the record, reset the trigger flag as not triggered and update the number of days for the record
self.isTrigger = false
self.nowDay = day
}
if (self.isTrigger == false && hour == self.triggerHour && minute >= self.triggerMinute) {
// Determine whether the time is triggered, if it meets the conditions, set the flag isTrigger to true to indicate that it has been triggered
self.isTrigger = true
return true
}
return false // does not meet the trigger condition, that is, it is not triggered
}
return self // return the constructed object
}
function main() {
var q = $.NewTaskQueue()
var p = $.NewPositionManager()
// You can write: var t = CreateAlarmClock(14, 58)
// You can write: var t1 = CreateAlarmClock(9, 0)
var symbol = "i2009"
while (true) {
if (exchange.IO("status")) {
exchange.SetContractType(symbol)
var r = exchange.GetRecords()
if(!r || r.length <20) {
Sleep(500)
continue
}
if (/*Judging the conditions for opening a position at 9:00*/) {// You can write: t1.Check()
var fast = TA.MA(r, 2)
var slow = TA.MA(r, 5)
var direction = ""
if (_Cross(fast, slow) == 1) {
direction = "buy"
} else if(_Cross(fast, slow) == -1) {
direction = "sell"
}
if(direction != "") {
q.pushTask(exchange, symbol, direction, 1, function(task, ret) {
Log(task.desc, ret)
})
}
}
if (/*Judging 14:58 conditions for closing the position near the market close*/) {// You can write: t.Check()
p.CoverAll()
}
q.poll()
LogStatus(_D())
} else {
LogStatus(_D())
}
Sleep(500)
}
}
```
Put the CreateAlarmClock function we have implemented in the strategy, and construct two "alarm clock" objects at the beginning of the main function. In the strategy to determine the position of opening and closing, add the code that the "alarm clock" object calls the Check function, such as the commented out part of the code.
## Backtest
You can see the backtest, opening positions after 9 am and closing positions at 14:58 pm.
It can also be used for multi-variety strategies. Multiple such "alarm clock" objects can be created in multi-variety strategies for time control of multiple varieties without affecting each other.
## Python language implements alarm clock class
Implementation and test code:
```
import time
class AlarmClock:
def __init__(self, triggerHour, triggerMinute):
self.isTrigger = False
self.triggerHour = triggerHour
self.triggerMinute = triggerMinute
self.nowDay = time.localtime(time.time()).tm_wday
def Check(self):
t = time.localtime(time.time())
hour = t.tm_hour
minute = t.tm_min
day = t.tm_wday
if day != self.nowDay:
self.isTrigger = False
self.nowDay = day
if self.isTrigger == False and hour == self.triggerHour and minute >= self.triggerMinute:
self.isTrigger = True
return True
return False
def main():
t1 = AlarmClock(14,58)
t2 = AlarmClock(9, 0)
while True:
if exchange.IO("status"):
LogStatus(_D(), "Already connected!")
exchange.SetContractType("rb2010")
ticker = exchange.GetTicker()
if t1.Check():
Log("Market Close", "#FF0000")
if t2.Check():
Log("Market Open", "#CD32CD")
else :
LogStatus(_D(), "not connected!")
Sleep(500)
```
Backtest test run:
It should be noted that for backtest, the K-line cycle of the bottom layer cannot be set too large, otherwise the time detection point may be skipped directly and there will be no trigger.

[GROWI](https://growi.org/en/), an open-source in-house wiki, has a plug-in feature. This feature allows you to display your own data or customize the display.
This article will explain the procedure for developing a GROWI plug-in. This is as much as we know, as we have not yet grasped the whole process, but please use it as a reference during development.
## Types of plug-ins
There are three types of GROWI plug-ins
- script
- theme
- template
This time, we will focus on scripts.
## Template
We have created a template that can be used to create plug-ins. This is the base template.
[goofmint/growi-plugin-script-template](https://github.com/goofmint/growi-plugin-script-template)
## About files to be edited
After downloading or forking the above repository, edit the following files.
### package.json
Describe the plugin information. Change `name` and `description`.
```js
{
"name": "growi-plugin-script-template", // change this name
"version": "1.0.0",.
"description": "GROWI plugin template for script", // change this description
// : omitted
}
```
#### Installing Dependent Libraries
After renaming, install the libraries required for plugin development. Use the `yarn` command.
```bash
$ yarn
```
### client-entry.tsx
This is the file that is loaded when the plugin is executed. It is where you describe the plugin process. The `options.components` contains the tag information, so you can change the plugin's default behavior.
```typescript
import config from '. /package.json';
import { helloGROWI } from '. /src/Hello';
import { Options, Func, ViewOptions } from '. /types/utils';
declare const growiFacade : {
markdownRenderer?
optionsGenerators: {
customGenerateViewOptions: (path: string, options: Options, toc: Func) => ViewOptions, generateViewOptions: (path: string, options: Options, toc: Func)
generateViewOptions: (path: string, options: Options, toc: Func) => ViewOptions, ViewOptions
}, }
}, }
}; }
const activate = (): void => {
if (growiFacade == null || growiFacade.markdownRenderer == null) {
return;
}
const { optionsGenerators } = growiFacade.markdownRenderer;
optionsGenerators.customGenerateViewOptions = (. .args) => {
const options = optionsGenerators.generateViewOptions(. .args);
// extract the A tag
const { a } = options.components;
options.components.a = helloGROWI(a); // Overwrite the drawing content of the A tag
return options; }
}; }
}; }
const deactivate = (): void => {
};
// register activate
if ((window as any).pluginActivators == null) {
(window as any).pluginActivators = {}; }
}
(window as any).pluginActivators[config.name] = {
activate, deactivate, deactivate, deactivate, deactivate
deactivate, }
}; }
```
The following tags can be specified. When processing these tags, the plugin will override the process.
- a
- code
- h1
- h2
- h3
- h4
- h5
- h6
- lsx
- ref
- refs
- refimg
- refsimg
- gallery
- drawio
- table
- mermaid
- attachment
- img
For example, to change the processing of the `a` tag, use the following
```typescript
options.components.a = helloGROWI(a);.
```
### src/Hello.tsx
This is the file with `helloGROWI` above. Feel free to change the name of this function. In the following case, no processing is done.
```jsx
import '. /Hello.css';.
export const helloGROWI = (Tag: React.FunctionComponent<any>): React.
return ({ children, . .props }) => {
return (
<Tag {. .props}>{children}</Tag>
);
};
};
```
### src/Hello.css
CSS file. Feel free to change it.
## Preview
Change ``src/Demo.tsx`` to see the actual display.
```jsx
import React from 'react';
import ReactDOM from 'react-dom/client';
import { helloGROWI } from '. /Hello';
const href = 'https://growi.org/';
const HelloGROWI = helloGROWI(() => <a href={href}>Hello, GROWI</a>);
ReactDOM.createRoot(document.getElementById('root') as HTMLElement).render(
<React.StrictMode>
<HelloGROWI
href={href}
>Hello, GROWI</HelloGROWI>
</React.StrictMode>,.
);
```
Preview with the `vite` command or `yarn dev`.
```bash
$ yarn dev
```
Now you can see the demo display at `http://localhost:5173/demo.html`.
## Build the plugin
You can build the plugin with `yarn build`.
```bash
$ yarn build
```
If the build succeeds, the plugin files will be output in the `dist` directory.
## Install the plugin
You can install the plugin from the GROWI administration page.
## Publish the plugin
When the plugin is ready, publish it on GitHub repository and add a `growi-plugin` topic. It will then appear in the GROWI plugin list.
[GROWI plugin | GROWI.org](https://growi.org/plugins)
## Summary
Developing a plugin for GROWI is not difficult if you use a template. Please customize your own GROWI!

- Errors
- debugger keyword
constructor function:
A constructor function is a special function used to create objects in JavaScript.
A constructor function is created like this:
```
function Car(make, model, year) {
this.make = make;
this.model = model;
this.year = year;
}
```
A constructor function named Car is created here. A constructor function is used to create a new object and usually starts with an uppercase letter.
This function has make, model, and year parameters, which represent the properties of the newly created object.
The this keyword specifies the object being created:
this Keyword:
The value of the this keyword depends on how you call the function. In constructor functions, this refers to the newly created object. Within methods, this refers to the object on which the method was called.
Create a new object:
```
let myCar = new Car('Toyota', 'Corolla', 2020);
```
Here the Car constructor function is called using the new keyword and a new object is created. This call performs the following tasks:
- A new empty object is created.
- The created object is attached to this context.
- The Car function populates a new object with this: The make, model, and year properties take the values Toyota, Corolla, and 2020.
- The constructor function automatically returns the newly created object and attaches it to the myCar variable.
Export object properties to cansole:
```
console.log(myCar.make);
```
Here, after the myCar variable is created, we output the output via console.log to access its make property. This code outputs the value Toyota to the console because the make property of the myCar object is set to Toyota.
**JAVASCRIPT ERRORS**
types of errors
- ReferenceError
- SyntaxError
- TypeError
- URIError
- EvalError
- InternalError:
1-ReferenceError:
A ReferenceError occurs when a particular variable or function does not exist or is not defined.
```
console.log(test);
```
cansole:
2-SyntaxError:
SyntaxError Occurs when there is a syntax error in JavaScript code. These errors represent code violations.
```
a =; 5; //
```
Here a =; is written incorrectly because the = operator is not used correctly.
cansole:
3-TypeError:
TypeError occurs when a particular action or operation is performed against a value of the wrong type.
```
"abc".toFixed(5);
```
Here the toFixed method only applies to numeric values, but it is applied to string values.
cansole:
4-URIError:
URIError occurs in case of wrong usage related to URI (Uniform Resource Identifier). These errors can occur when the decodeURI(), decodeURIComponent(), encodeURI(), and encodeURIComponent() functions are called with incorrect parameters.
```
decodeURIComponent('%');
```
An error occurs here because the % sign is invalid.
cansole:
5-EvalError:
An EvalError can occur as a result of an incorrectly used eval() function in a program. However, since ES5, EvalError is almost deprecated and rarely encountered.
```
eval("foo bar");
```
After ES5, EvalError is usually replaced by other errors.
cansole:
6-InternalError:
InternalError is caused by an internal problem or limitation in the JavaScript engine. These errors are rare and often occur when the depth of recursion is exceeded or when other internal errors occur within the JavaScript interpreter.
```
function recurse() {
recurse();
}
recurse();
```
Here, the recursion depth is exceeded due to the function calling itself indefinitely.
cansole:
A try-catch block is used to catch and handle errors in JavaScript. Correct handling and handling of errors is important to ensure the stability of the application.
**debugging**
In JavaScript, the debugger keyword is used to analyze the code step by step, simplifying the process. This keyword allows you to stop and analyze the status of all code written in javascript, functions, code running in the browser or other debugging tools.
Debugging tasks:
The debugger keyword stops reading the code at the specified location and invokes the debugger. This is especially useful for understanding complex codes and detecting errors.
Where the code is interrupted, variables can be observed and their values analyzed. This makes it easier to quickly find and fix errors. We can check all the written codes one by one and see the result.
The debugger keyword works:
```
function name1() {
console.log('name1');
}
function name2() {
console.log('name2');
}
function name3() {
console.log('name3');
}
debugger
name1();
debugger
name2();
debugger
name3();
```
In this code, we can analyze the functions written from the top of the functions called by calling the debug keyword and moving down from the top, that is, we can analyze the functions and results.
debugging:
cansole:
Precautions When Using the Debugger Keyword:
Remove in production: The debugger keyword should be removed in a production environment. Otherwise, it may cause inconvenience to users.
Usage Limitation: Use the debugger keyword only where necessary and in short-term analysis processes. You shouldn't have too many debugger keywords in your code.
The debugger keyword is a powerful tool in JavaScript for stopping code execution, observing variables, and finding errors. With this keyword, you can analyze the code step by step and quickly identify and fix complex problems. It is important to know how to use the debugger keyword and its benefits to make the debugging process efficient.

1,893,188 | The Role of Asset Allocation in Portfolio Management | Portfolio management is the art and science of ascertaining investment mix and policy, aligning... | 0 | 2024-06-19T06:26:02 | https://dev.to/sonal_502242aca042c126125/the-role-of-asset-allocation-in-portfolio-management-49h1 | portfolio, assets, education, allocation |
Portfolio management is the art and science of ascertaining investment mix and policy, aligning assets to goals, and managing risk and performance. It entails allocating assets and managing investments in such a way that the portfolio is consistent with the investor's risk tolerance, financial objectives and the investment period.
The primary role of portfolio management is to maximise returns on various investments while minimising their risks.
The portfolio management process comprises processes such as goal setting, asset allocation, and continuing management and monitoring.
Asset Allocation - A Key Component of Portfolio Management
Asset allocation is an essential aspect of portfolio management that entails allocating investments among multiple asset classes, including stocks, cash, bonds and alternative investments. It aims to maximize the balance of risk and reward in a portfolio depending on investors' financial objectives, risk tolerance, and investment lifecycle.
But how does it impact the portfolio management process?
Let’s understand this by examining the key components and importance of asset allocation in portfolio management.
**Diversification**
One of the main advantages of asset allocation is diversification, which involves distributing assets across several asset classes to minimise risk. Each asset type behaves differently depending on market conditions and allows investors to reduce the impact of poor performance in a particular asset class on the total portfolio, for example - Stocks have the potential for high gains but are more volatile, and bonds provide more consistent yields and income but have lesser growth potential, while cash offers liquidity and stability but yields less return.
Risk Handling
Asset allocation is necessary for managing risk in a portfolio. By adjusting the proportion of different asset classes, investors can align their portfolios with their risk tolerance. For instance, cautious investors may allocate more to bonds and cash, while aggressive investors may allocate more to stocks and alternative investments.
**Profit Maximisation**
Profit maximisation is a key objective in portfolio management, and asset allocation is critical to achieving it. Returns can be optimized and overall portfolio performance improved by carefully selecting a mix of assets that match an investor's risk tolerance and investment period. One of the key profit-maximizing tactics is to discover asset classes with high prospective returns.
**Adapting to Market Conditions**
Economic considerations, inflation, interest rates and geopolitical events impact market movements. Portfolio adjustment facilitates optimal risk-reward alignment. Whereas, Tactical portfolio adjustments exhibit market conditions and opportunities. Overall, strategic asset allocation considers the investor's risk tolerance and investment goals in portfolio management.
How to Implement Asset Allocation in Portfolio Management?
Evaluate Risk Tolerance
To gauge risk tolerance, you as an investor must consider their financial status, age, and investment experience. Younger investors might take greater risks with a bigger allocation to shares, while retirees may prefer stability in the form of bonds.
Determine Investment Goals
Setting clear investment goals can help you determine the viable asset mix. For instance, a long-term goal, such as retirement, might have a large allocation to growth assets, like equities.
Calculate Investment Period
Determining the investment period can create a tremendous impact on asset allocation. Long-term investment goals can balance high volatility with a large allocation to equities, while short-term objectives may require a more conventional strategy or measures.
**Continuously Monitor and Rebalance**
Regular monitoring and rebalancing are necessary due to changing market conditions and personal circumstances. Regular monitoring ensures that the portfolio remains in line with the investor's objectives and risk tolerance. Rebalancing helps to preserve the appropriate asset allocation by accounting for market movements.
Challenges in Implementing Asset Allocation - Portfolio Management
Market Uncertainty
Market volatility can hamper asset class performance, by making it difficult to maintain suitable allocations. Thus, Investors must be prepared for short-term volatility and have measures in place to handle it, such as rebalancing or using hedging tactics.
**Behavioural biases**
Common biases such as overconfidence, herd behaviour and loss aversion can lead to poor investment-related decisions, such as following market trends or selling assets during the downtrend, and impact the investors’s portfolio negatively.
Political and Economic Factors
Factors such as inflation, downturns, and interest rate changes, can impact asset class performance and require investors to modify their strategy accordingly. For instance, rising interest rates may negatively affect the price of bonds, while geopolitical concerns might enhance market volatility. Hence, staying updated with global economic and political changes is essential for making informed and timely portfolio variations.
**Conclusion**
Asset allocation is a vital component of effective portfolio management. Diversifying investments across various asset classes allows investors to manage risks, maximize returns, and match their portfolios with their financial goals.
So, whether you are using the strategic or tactical approach, an effective asset allocation requires a complete knowledge of risk tolerance, investing goals, and period. Despite the challenges of market volatility and behavioural biases, disciplined asset allocation and regular portfolio rebalancing can greatly enhance the chances of long-term investing success.
As the financial landscape evolves with time, a strong asset allocation strategy remains crucial for navigating the complexities of the investment sphere.

1,893,172 | The Future of NFT Gaming with Sandbox Clone Scripts | Introduction The realm of digital assets and blockchain technology has... | 27,619 | 2024-06-19T06:07:27 | https://dev.to/aishik_chatterjee_0060e71/the-future-of-nft-gaming-with-sandbox-clone-scripts-15f0 | ## Introduction
The realm of digital assets and blockchain technology has expanded
significantly over the past few years, introducing innovative ways to leverage
technology in various sectors, including gaming. One of the most notable
advancements is the integration of Non-Fungible Tokens (NFTs) into gaming
platforms, which has revolutionized how players interact with games, offering
them a unique blend of entertainment and investment opportunities. This
introduction will delve into the concept of NFT gaming and explore the
specific role and importance of Sandbox Clone Script within this burgeoning
sector.
## Overview of NFT Gaming
NFT gaming combines traditional gaming mechanics with the unique aspects of
NFTs, allowing players to own, buy, sell, and trade in-game assets as digital
tokens on the blockchain. Unlike standard digital assets in traditional games,
NFTs have distinct, verifiable properties that make them unique and hence,
potentially more valuable. This uniqueness and the ability to prove ownership
securely make NFTs particularly appealing in the gaming world.
## Importance of Sandbox Clone Script in the NFT Space
The Sandbox Clone Script is a vital tool in the NFT space, particularly for
developers and entrepreneurs looking to launch their own virtual worlds and
gaming platforms. This script is essentially a ready-made solution that mimics
the core functionalities of the popular NFT game, The Sandbox, which allows
users to create, own, and monetize their gaming experiences using NFTs. By
using a clone script, developers can significantly reduce the time and
resources required to develop complex code from scratch.
## What is Sandbox Clone Script?
The Sandbox Clone Script is a comprehensive, ready-made software solution
designed to replicate the core functionalities of The Sandbox, a popular
virtual world and gaming ecosystem built on blockchain technology. This script
enables entrepreneurs and businesses to launch their own decentralized virtual
environment where users can create, own, and monetize their gaming experiences
using cryptocurrency and NFTs (Non-Fungible Tokens).
## Benefits of Using Sandbox Clone Script
### Quick Market Entry
One of the primary advantages of using a Sandbox clone script is the ability
to quickly enter the market. Developing a complex platform like The Sandbox
from scratch requires significant time and resources. By using a clone script,
businesses can bypass many of the initial development stages, such as
planning, coding, and testing foundational elements. This not only speeds up
the launch process but also allows businesses to capitalize on market trends
more rapidly.
### Cost-Effectiveness
Another significant benefit of using a Sandbox clone script is cost-
effectiveness. Developing a digital platform from the ground up can be
incredibly costly, involving expenses related to software development,
security protocols, server costs, and maintenance. Clone scripts, on the other
hand, are typically less expensive because they leverage existing software
architectures and designs.
### Scalability and Flexibility
Scalability and flexibility are crucial aspects of any software development,
especially when dealing with a Sandbox clone script. Scalability refers to the
ability of the system to handle a growing amount of work or its potential to
accommodate growth. Flexibility, on the other hand, involves the ease with
which the system can adapt to changes without significant additional costs or
modifications.
## Challenges in Implementing Sandbox Clone Script
### Technical Challenges
The technical challenges in implementing a Sandbox clone script are vast and
varied, depending on the complexity of the script and the infrastructure it
requires. These challenges include ensuring the scalability of the backend
systems, integrating various APIs, and maintaining data integrity and security
throughout the platform.
### Market Competition
The market competition in the realm of NFT gaming, particularly with platforms
like The Sandbox, is intensifying as more players enter the space. The Sandbox
itself has carved a niche by allowing users to create, own, and monetize their
gaming experiences using blockchain technology. This unique proposition has
attracted various competitors, each aiming to innovate and capture a portion
of the market.

</ul>
<h1>Part 6 Creating a Simple Firewall</h1>
<p>Welcome to Part 6. In this chapter we will extend the work we did in part 5
where we looked at a simple PerCpuArray map to count packets.</p>
<p>Using eBPF we can create a simple firewall/router. With a small amount of code we can
drop or redirect packets based on the source and destination addresses.
We will implement this in several stages using a hashmap to store the
configuration.
The initial version will load the IP addresses from user space and to the eBPF kernel code,
and with each iteration we can add more functionality.</p>
<p>As before, generate the code
using `</p>
<pre><code class="language-shell">cargo generate https://github.com/aya-rs/aya-template
</code></pre>
<p>I called the project <code>firewall-001</code></p>
<h1>Modify the generated source code</h1>
<p>Modify ebpf firewall-001-ebpf/Cargo.toml to include a dependency
for the network-types crate:</p>
<pre><code class="language-cargo">[dependencies]
aya-ebpf = "0.1.0"
aya-log-ebpf = "0.1.0"
firewall-001-common = { path = "../firewall-001-common" }
network-types = "0.0.5"
</code></pre>
<p>Then modify the ebpf code in <code>firewall-001-ebpf/src/main.rs</code>
so we can add HashMap map </p>
<p>In the eBPF code <code>firewall-001-ebpf/src/main.rs</code>
the header section should look like this:</p>
<pre><code class="language-rust"> use aya<em>ebpf::{bindings::xdp</em>action,
macros::{xdp,
map }, // <---- added map macro
programs::XdpContext,
maps::HashMap // <--- added hashmaps
};
use aya<em>log</em>ebpf::info;
use core::mem; // <--- added memory crate
use network_types::{ // Added
eth::{EthHdr, EtherType},
ip::{IpProto, Ipv4Hdr},
tcp::TcpHdr,
udp::UdpHdr,
};
</code></pre>
<p>Add the map definition, as in Part 5 we define the map in the ebpf code in
<code>firewall-001/firewall-001-ebpf/src/main.rs</code></p>
<pre><code class="language-rust"> #[map(name = "SRC<em>IP</em>FILTER")]
static mut SRC<em>IP</em>FILTER: HashMap<u32, u8> =
HashMap::<u32, u8>::with<em>max</em>entries(1024, 0);
</code></pre>
<p>As we are working with the eBPF subsystem in the kernel we
will need to work directly with raw pointers. This is where
will use the <code>core::mem crate</code>. We need to check the size
of data or the verifier will complain</p>
<pre><code class="language-rust"> fn ptr_at<T>(ctx: &XdpContext, offset: usize) -> Result<*const T, ()> {
let start = ctx.data();
let end = ctx.data_end();
let len = mem::size_of::<T>();
if start + offset + len > end {
return Err(());
}
Ok((start + offset) as *const T)
}
</code></pre>
<p>The packet parsing will be done in the try<em>firewall</em>001 function. We will peel off
the layers of each packet till we match the rules passed in by the map IP</p>
<pre><code class="language-rust"> let ethhdr: *const EthHdr = ptr_at(&ctx, 0)?; //
match unsafe { (*ethhdr).ether_type } {
EtherType::Ipv4 => {
info!(&ctx, "received IPv4 packet");
}
EtherType::Ipv6 => {
info!(&ctx, "received IPv6 packet");
return Ok(xdp<em>action::XDP</em>DROP);
}
<em> => return Ok(xdp_action::XDP</em>PASS),
}
</code></pre>
<p>We pass all IPv4 packets but drop any IPv6 packets, in the next section
we start to unpack the IPv4 header, first we get the port </p>
<pre><code class="language-rust"> let source_port = match unsafe { (*ipv4hdr).proto } {
IpProto::Tcp => {
let tcphdr: *const TcpHdr =
ptr_at(&ctx, EthHdr::LEN + Ipv4Hdr::LEN)?;
u16::from_be(unsafe { (*tcphdr).source })
}
IpProto::Udp => {
let udphdr: *const UdpHdr =
ptr_at(&ctx, EthHdr::LEN + Ipv4Hdr::LEN)?;
u16::from_be(unsafe { (*udphdr).source })
}
_ => return Err(()),
};
</code></pre>
<p>Then we check if the ip address is one in our list of blocked ip addresses</p>
<pre><code class="language-rust"> if unsafe { SRC<em>IP_FILTER.get(&source_addr).is</em>some() } {
info!(&ctx, "dropping packet ...");
return Ok(xdp<em>action::XDP</em>DROP);
}
</code></pre>
<p>The user space code reads a YAML config file that contains a list of IP addresses and
an instruction as to what to do to the packets coming from that address. </p>
<pre><code class="language-shell"> ---
"127.0.0.1" : "block"
"10.0.0.1" : "block"
"10.0.0.2" : "block"
</code></pre>
<p>We will use the figment crate to parse the YAML config file into a
hashmap that can be loaded into the eBPF map. </p>
<p>Modify the Cargo.toml file in firewall-001/Cargo.toml to include
the dependency:</p>
<pre><code class="language-cargo"> figment = { version = "0.10.18", features = ["yaml", "env"] }
</code></pre>
<p>And then add the following to the user space rust code in firewall-001/src/main.rs</p>
<pre><code class="language-rust"> use std::net::Ipv4Addr;
use figment::{Figment, providers::{Yaml, Format}};
...
#[tokio::main]
async fn main() -> Result<(), anyhow::Error> {
let opt = Opt::parse();
let config: HashMap<String,String> = Figment::new()
.merge(Yaml::file("config.yaml"))
.extract()?;
</code></pre>
<p>Here we extract the config file into a <code>HashMap<String,String></code>
Once we have the entries from our config file in the a HashMap
we can load them into the hashmap created in the ebpf code. </p>
<p>This is the opposite of what we did in the Part 5 where
we data was stored in the map on the eBPF side and passed
to the user space program. Here we load the data from user space
and pass it to the eBPF using the map.</p>
<pre><code class="language-rust"> let mut src<em>ip_filter : ayaHashMap<</em>, u32, u8> =
ayaHashMap::try<em>from( bpf.map_mut("SRC_IP</em>FILTER").unwrap())?;
...
for (k, v) in config {
if v == "block" {
let addr : Ipv4Addr = k.parse().unwrap();
println!("addr {:?}" , addr);
let <em> = src_ip</em>filter.insert(u32::from(addr), 1, 0);
}
}
</code></pre>
<p>The IP addresses get loaded into the map and are then visible in the
eBPF code running in the kernel.</p>
<p>We can use the loopback address 127.0.0.1 to test whether the firewall works
First load the eBPF program and attach it to the loopback interface</p>
<pre><code class="language-shell"> RUST_LOG=info cargo xtask run -- -i lo
</code></pre>
<p>We can check that it is loaded using bpftool</p>
<pre><code class="language-shell"> $ sudo bpftool prog list | grep -A 5 firewall
5118: xdp name firewall_002 tag 64a3874abd9070d2 gpl
loaded_at 2024-05-01T23:27:54-0700 uid 0
xlated 7008B jited 3759B memlock 8192B map_ids 1532,1534,1533,1535
</code></pre>
<p>We can use the netcat program to test it.
In one terminal start a server listening on port 9090</p>
<pre><code class="language-shell"> nc -l 9090
</code></pre>
<p>In another terminal send data to the server:</p>
<pre><code class="language-shell"> echo "the quick brown fox jumped over the lazy dog" | nc 127.0.0.1 9090
</code></pre>
<p>In the terminal running the cargo command:</p>
<pre><code class="language-shell"> 2024-05-02T06:37:27Z INFO firewall_002] received IPv4 packet
[2024-05-02T06:37:27Z INFO firewall_002] dropping packet ...
...
</code></pre>
<p>In the netcat server window there will no output showing receipt of a packet</p>

Here are some of the key ways the gaming industry is utilizing blockchain:
**In-Game Economies and Assets:**
Blockchain technology is enabling the creation of decentralized in-game economies, where players can truly own and trade digital assets, such as virtual land, items, or characters.
This allows for the development of player-driven economies and the ability to transfer or sell these assets outside of the game.
**Non-Fungible Tokens (NFTs):**
The gaming industry has been at the forefront of adopting and integrating NFTs, which are unique digital assets stored on the blockchain.
NFTs are being used to represent in-game items, collectibles, and even characters, providing players with true digital ownership and the ability to trade these assets on secondary markets
**Play-to-Earn (P2E) Models:**
Blockchain-based games are increasingly incorporating P2E models, where players can earn cryptocurrency or other blockchain-based rewards by participating in various in-game activities, such as completing tasks, winning matches, or engaging in the in-game economy.
This creates new revenue streams for players and incentivizes active participation in the game.
**Cross-Game Interoperability:**
Blockchain technology enables the development of interoperable gaming ecosystems, where digital assets and characters can be used across multiple games or platforms.
This allows for the creation of more robust and interconnected gaming experiences, where players can seamlessly transition between different games while maintaining their digital ownership.
**Decentralized Governance and Community Involvement:**
Some blockchain-based games are incorporating decentralized governance models, where players can participate in decision-making processes, such as voting on game updates or the allocation of in-game resources.
This fosters a sense of community ownership and empowers players to shape the direction of the game they are engaged with.
**Transparent and Secure Transactions:**
Blockchain technology provides a secure and transparent platform for in-game transactions, reducing the risks of fraud, hacking, or centralized control over the game's economy.
This can help build trust and confidence among players, as they can verify the authenticity and ownership of their digital assets.
These are just a few examples of how the gaming industry is leveraging blockchain technology to create more immersive, player-centric, and decentralized gaming experiences. As the technology continues to evolve, we can expect to see even more innovative applications of blockchain in the gaming industry.
Sure, let me expand a bit more on how the gaming industry is leveraging blockchain technology:
**Blockchain-based Game Platforms:**
Several blockchain-based game platforms have emerged, providing the infrastructure and tools for developers to create blockchain-powered games.
Examples include platforms like Enjin, Gala Games, and Axie Infinity, which offer features such as NFT marketplaces, in-game economies, and cross-game asset compatibility.
**Blockchain Gaming Ecosystems**:
The concept of "GameFi" (Game Finance) has gained traction, where blockchain-based games are integrated with decentralized finance (DeFi) protocols.
This allows players to earn, lend, or borrow cryptocurrency, and participate in the broader DeFi ecosystem within the context of the game.
**Blockchain-based Game Engines**:
Game engine providers, such as Unreal Engine and Unity, are integrating blockchain capabilities into their platforms, making it easier for developers to incorporate blockchain features into their games.
This includes support for NFTs, in-game economies, and other blockchain-related functionalities.
**Blockchain-based Esports and Tournaments**:
The esports industry is also exploring the use of blockchain technology to create more transparent and decentralized tournament platforms.
This can enable secure player registrations, transparent prize pool management, and the ability to tokenize tournament participation or winnings.
**Blockchain-based Game Publishing and Distribution**:
Some blockchain-based platforms are exploring decentralized game publishing and distribution models, where developers can directly reach players without the need for traditional game stores or publishers.
This can potentially provide more favorable revenue sharing for developers and more control over their intellectual property.
**Blockchain-powered Player Incentives**:
Blockchain-based games are experimenting with novel player incentive models, such as rewarding players for various in-game activities or for contributing to the game's development and community.
These incentives can take the form of cryptocurrency, NFTs, or other blockchain-based rewards.
As the blockchain technology continues to evolve and become more widely adopted, we can expect to see even more innovative and disruptive applications of this technology within the gaming industry, transforming the way games are developed, published, and experienced by players.

1,893,017 | Understanding JWT Authentication: A Complete Guide | Authentication is a critical aspect of web development, ensuring secure access to resources and... | 0 | 2024-06-19T06:02:00 | https://raajaryan.tech/jwt-authentication | javascript, node, beginners, react |
Authentication is a critical aspect of web development, ensuring secure access to resources and protecting sensitive data. JSON Web Tokens (JWT) have become a popular choice for handling authentication in modern web applications due to their simplicity and security. In this step-by-step guide, we'll walk through implementing JWT authentication in a MERN stack application.
## What is JWT?
JSON Web Token (JWT) is an open standard (RFC 7519) for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed. JWTs can be signed using a secret (with the HMAC algorithm) or a public/private key pair using RSA or ECDSA.
## Key Concepts of JWT
1. **Header**: Contains metadata about the token, including the type of token and the signing algorithm.
2. **Payload**: Contains the claims, which are statements about an entity (typically, the user) and additional data.
3. **Signature**: Ensures that the token hasn't been altered. It is created by encoding the header and payload and signing them using a secret key or a public/private key pair.
## Step-by-Step Guide to Implement JWT Authentication
### Step 1: Setting Up Your MERN Stack
Ensure you have the following setup:
- **MongoDB** for the database
- **Express** for the server framework
- **React** for the front-end
- **Node.js** for the runtime environment
### Step 2: Install Necessary Packages
Start by installing the required packages using npm:
```bash
npm install express mongoose jsonwebtoken bcryptjs cors body-parser
```
### Step 3: Set Up the Server
Create a new file `server.js` and set up a basic Express server:
```javascript
const express = require('express');
const mongoose = require('mongoose');
const cors = require('cors');
const bodyParser = require('body-parser');
const app = express();
// Middleware
app.use(cors());
app.use(bodyParser.json());
// Connect to MongoDB
mongoose.connect('mongodb://localhost:27017/yourdbname', {
useNewUrlParser: true,
useUnifiedTopology: true,
});
const db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', () => {
console.log('Connected to MongoDB');
});
app.listen(5000, () => {
console.log('Server is running on port 5000');
});
```
### Step 4: Create User Model
Create a `User` model with Mongoose:
```javascript
const mongoose = require('mongoose');
const bcrypt = require('bcryptjs');
const userSchema = new mongoose.Schema({
username: { type: String, required: true, unique: true },
password: { type: String, required: true },
});
userSchema.pre('save', async function (next) {
if (this.isModified('password') || this.isNew) {
const salt = await bcrypt.genSalt(10);
this.password = await bcrypt.hash(this.password, salt);
}
next();
});
const User = mongoose.model('User', userSchema);
module.exports = User;
```
### Step 5: Implement Registration and Login Routes
Create `auth.js` in the `routes` directory for handling authentication:
```javascript
const express = require('express');
const jwt = require('jsonwebtoken');
const bcrypt = require('bcryptjs');
const User = require('../models/User');
const router = express.Router();
const secretKey = 'yourSecretKey'; // Store this in an environment variable
// Registration
router.post('/register', async (req, res) => {
const { username, password } = req.body;
try {
let user = await User.findOne({ username });
if (user) {
return res.status(400).json({ msg: 'User already exists' });
}
user = new User({ username, password });
await user.save();
res.status(201).json({ msg: 'User registered successfully' });
} catch (err) {
res.status(500).json({ error: err.message });
}
});
// Login
router.post('/login', async (req, res) => {
const { username, password } = req.body;
try {
const user = await User.findOne({ username });
if (!user) {
return res.status(400).json({ msg: 'User does not exist' });
}
const isMatch = await bcrypt.compare(password, user.password);
if (!isMatch) {
return res.status(400).json({ msg: 'Invalid credentials' });
}
const payload = { userId: user._id };
const token = jwt.sign(payload, secretKey, { expiresIn: '1h' });
res.status(200).json({ token });
} catch (err) {
res.status(500).json({ error: err.message });
}
});
module.exports = router;
```
### Step 6: Protect Routes with JWT Middleware
Create a middleware to protect routes that require authentication:
```javascript
const jwt = require('jsonwebtoken');
const secretKey = 'yourSecretKey'; // Use the same key from your environment variable
const auth = (req, res, next) => {
const token = req.header('x-auth-token');
if (!token) {
return res.status(401).json({ msg: 'No token, authorization denied' });
}
try {
const decoded = jwt.verify(token, secretKey);
req.user = decoded.userId;
next();
} catch (err) {
res.status(401).json({ msg: 'Token is not valid' });
}
};
module.exports = auth;
```
### Step 7: Apply JWT Middleware to Protected Routes
Use the middleware to protect specific routes:
```javascript
const express = require('express');
const auth = require('./middleware/auth');
const router = express.Router();
// A protected route example
router.get('/protected', auth, (req, res) => {
res.status(200).json({ msg: 'You have accessed a protected route', userId: req.user });
});
module.exports = router;
```
### Step 8: Integrate Front-End with JWT Authentication
In your React application, you can manage JWTs using `localStorage` or `sessionStorage` for storing tokens and `axios` for making authenticated requests.
**Example of a login function in React:**
```javascript
import axios from 'axios';
const login = async (username, password) => {
try {
const res = await axios.post('http://localhost:5000/auth/login', { username, password });
const token = res.data.token;
localStorage.setItem('token', token);
// Redirect or perform further actions
} catch (err) {
console.error(err.response.data);
}
};
```
**Example of setting up `axios` to include JWT in headers:**
```javascript
import axios from 'axios';
const api = axios.create({
baseURL: 'http://localhost:5000',
});
api.interceptors.request.use(
config => {
const token = localStorage.getItem('token');
if (token) {
config.headers['x-auth-token'] = token;
}
return config;
},
error => {
return Promise.reject(error);
}
);
export default api;
```
### Conclusion
By following these steps, you should have a solid foundation for implementing JWT authentication in your MERN stack application. JWT provides a secure and scalable way to handle authentication, making it easier to protect your web application’s routes and resources.
Feel free to expand on this setup by adding features such as user roles, token refresh mechanisms, and enhanced security measures to further solidify your authentication process. Happy coding! | raajaryan |

Konstruktor funksiyasi (constructor function) JavaScriptda obyektlar yaratish uchun ishlatiladigan maxsus funksiyadir.
Konstruktor Funksiya shu ko'rinishda yaratiladi:
```
function Car(make, model, year) {
this.make = make;
this.model = model;
this.year = year;
}
```
Bu yerda Car nomli konstruktor funksiyasi yaratilgan. Konstruktor funksiyasi yangi obyekt yaratish uchun ishlatiladi va odatda katta harf bilan boshlanadi.
Bu funksiyada make, model, va year parametrlar bo'lib, ular yangi yaratilayotgan obyektning xususiyatlarini ifodalaydi.
this kalit so'zi yangi yaratilayotgan obyektni bildiradi:
this Kalit so'zi:
this kalit so'zining qiymati funksiyani qanday chaqirganingizga bog'liq. Konstruktor funksiyalarida this yangi yaratilgan obyektga ishora qiladi. Metodlar ichida esa this metod chaqirilgan obyektga ishora qiladi.
Yangi obyekt yaratish:
```
let myCar = new Car('Toyota', 'Corolla', 2020);
```
Bu yerda new kalit so'zi yordamida Car konstruktor funksiyasi chaqirilgan va yangi obyekt yaratilgan. Bu chaqiruv quyidagi vazifalarni bajaradi:
- Yangi bo'sh obyekt yaratiladi.
- Yaratilgan obyekt this konteks biriktiriladi.
- Car funksiyasi this orqali yangi obyektni to'ldiradi:
make, model, va year xususiyatlari Toyota, Corolla, va 2020 qiymatlarini oladi.
- Konstruktor funksiyasi avtomatik ravishda yangi yaratilgan obyektni qaytaradi va myCar o'zgaruvchisiga biriktiriladi.
Obyekt hususiyatlarini cansolega chiqarish:
```
console.log(myCar.make);
```
Bu yerda myCar o'zgaruvchisi yaratilgandan so'ng, uning make xususiyatiga kirish uchun console.log orqali natijani chiqaramiz. Bu kod Toyota qiymatini konsolga chiqaradi, chunki myCar obyektining make xususiyati Toyotaga teng qilib belgilangan.

This week means yesterday on Monday, 17 June 2024, as usual, I was writing an email for newsletter subscribers, (it’s FREE so feel free to [subscribe](http://ihatereading.in/subscribe)) between writing and sending emails I’ve to follow the following process
* Write email in a rich text editor, sometimes google doc or Notion or medium editor
* Convert Email into HTML format
* Add HTML to my backend email design tool, currently using [courier.com](https://app.courier.com/)
* Trigger API to send bulk emails using courier SDK
Of course, I can use alternatives like Mailchimp, Sendgrid, Twilio, Sendbird and so on.
Here is the extensive list of email supporters for developers
* Sendgrid
* Twilio
* Mailchimp
* Courier
* Resend
* Sendbird
* Gmail API
* AWS API
* Mailgun
* Outlook
Top 30+ Email API collection for developers
[Top 35 Email APIs/Services for Developers](https://ihatereading.in/t/5lDAaNTTc7nNQxYVomIv/top-35-email-apis-services-for-developers?source=post_page-----d2e8da9268f2--------------------------------)
### Collection of Email APIs for developers
[iHateReading](ihatereading.in)
Let’s start the picture, we have an extensive list of email providers and supporters.
One can easily integrate and start creating emails, and notifications but that’s not the real problem.
## Ice under the water
Every website needs emailing services for the following reasons
* Newsletter emails
* Product emails
* Notifications emails
* Weekly subscription emails
Every product may need a lot of different kinds of emails per week or sometimes twice a day.
Most of the above tools either provide a way to craft and design emails within the platform itself or allow developers to send emails directly via an HTML file.
The process is simplified in 2 ways
* Send email via HTML
* Craft HTML template and send the template
But this seems to have one bottlenecks
* One need to craft email everytime manually
* One need to use platform to manage subscribers or users
## Sending Bulk Emails to subscribers
Let me explain how, we run a newsletter business for iHateReading. Send newsletter to our 1k+ subscribers once a week.
* I’ve to craft email HTML manually on courier.app because that is the platform I was using
* Then I’ve to save this HTML and publish it
* Once the HTML is published as the template on courier app, I get the template Id
* Using courier SDK in Node.js server I send the email to my subscribers by passing template Id as well
* Courier SDK then send the template to my list users or subscribers
Now, even If I use Mailchimp, Sendgrid or Twilio all of them allow me to almost do the same process, create HTML manually and send emails to bulk users.
## Existing Problem
Most of the tools doesn’t simply allow to send bulk emails, they first want to store the bulk user data such as email address followed by sending bulk emails.
The problem with existing ones are
* Not everytime I want to share my subscribers with these platforms
* Why to craft and create HTML manually
* HTML creating process should be handled dynamically instead
* Bulk email and subscriber management should be done programmatically and securely
## Resend at Rescue
I don’t want to go into pros and cons, A vs B.
Sendgrid, Twilio, Mailchimp, AWS SES and Gmail API are the top most used notification tools in the world.
But as I’ve explained the problem we have faced with them for our product and resend helps us to somehow solve it.
**Here’s how**
* Resend allow you to craft emails programmatically
* Resend provide SDK to send bulk emails directly as HTML without
* Resend allows to add/manage subscribers as audiences
* Resend provides a react-email npm module to create emails using React components such as Button, Inputs, Cards
check the example below
[React Email](https://demo.react.email)
Using react components developers can easily create an email template and convert it into HTML format to send as an HTML.
The resend package provides built-in components to support various component types.
We need more tools like Resend and npm modules for emailing and notification services.
Another problem we are encountering is debouncing emails and invalid email addresses, validating emails.
One tool should help developers validate email, create HTML, and create audiences dynamically or using SDK.
Sample Solution
* At iHateReading, we are using editors to write a newsletter
* Then we convert the editor content into HTML format
* Followed by sending this HTML as an email using resend SDK
* Add subscribers to the audience via resend SDK to subscribers
If we need to send another newly released email or product email we can do it but we can’t edit the HTML file and editing the HTML file and components look is what we want to add in future.
I hope you have understood the problem and how are currently solving it.
Resend sounds pretty close to what we want to achieve, our main target is to completely automate the process.
Conclusion
==========
An extensive list of the emailing and notifications API, more than 30+ tools are available.
But still, most or all of them don’t provide a way to craft emails dynamically as well manage subscribers and send HTML, take care of email validation, alter the process of resending debounced emails and so on.
We at iHateReading, ended up creating our custom tool to solve this problem of simply writing an editor to craft HTML and send this to our bulk users or audience
Sooner or later we will bring another feature to even edit the HTML file interface using drag and drop, CSS styling editors and so on.
That’s it for today, see you in the next one

As a beginner, I've heard the terms "front-end development", "back-end development", and "full stack development" but what exactly do they mean? Well, I learned that Ruby is a backend language. The backend is comparable to the gears in a clock; they are essential for a clock or watch to work but the owner doesn't actually see the gears turning (depending on some watches and clocks). The only difference is, users almost never will see or access server-side data infrastructure. Why you may ask? My answer is *drum-roll please* **backend frameworks**; such as Ruby on Rails and Sinatra. Sinatra is a lightweight framework that enables developers to make small applications
I understand that users don't actually see _routes_, _HTTP calls_ or _api tokens_ and most users are not aware that they can change the route of an address to get to the desired content (granted the content exists and unless that user is a computer whiz or works in the tech industry). | prettyalana |

Single sign-on (SSO) is an authentication procedure that permits users to access several applications with a single login credential. This simplifies your web experience by granting access to various web applications without the need to input your username and password repeatedly. Recognizing the innate vulnerabilities of passwords, the concept of SSO has evolved into what is now termed reduced sign-on ([RSO](https://identitymanagersite.wordpress.com/2017/01/12/difference-between-sso-and//)). This transition is driven by adopting multiple authentication methods tailored to the risk profiles inherent in different enterprise environments. For example, in an SSO software enterprise, users log on with their ID and password. This process gives them access to low-risk information and multiple applications like the enterprise portal. However, when the user tries to access higher-risk applications and information, like a payroll system, the software requires them to use a more potent form of authentication. These forms of authentication may include digital certificates, security tokens, smart cards, biometrics, or combinations.
The internet is stateless. The SSO systems must constantly check whenever you try to access a web page or click on a different URL if there is an authentication policy on the webpage or URL you're trying to access. This back-and-forth communication can cause traffic spikes between the user's browser, the application server, and security servers, especially in big organizations with many users and resources. Hence, modern SSO systems store authentication and permission policies in Lightweight Directory Access Protocol ([LDAP](https://en.wikipedia.org/wiki/Lightweight_Directory_Access_Protocol/)) directories. LDAP directories are designed for high-performance lookups, which address large traffic loads. Additionally, the system frequently uses LDAP directories for authentication.
## Advantages of Single Sign-on
These are the benefits SSO provides:
* **Reduced password fatigue**: SSO reduces the risks of combining short and feeble passwords and usernames. It also reduces the time spent for re-entering passwords for the same identity.
* **Reduced IT costs due to reduced help desk calls**: IT costs were reduced due to a decreased number of IT help desk calls about passwords. Analyst Gartner specifies in a report that only 20 to 50 percent of help desk inquiries in IT are associated with forgotten passwords or password resets. Many SSO solutions permit users to reset passwords, often with help desk support.
* **Better management control:** All network management data are kept in a single repository. This ensures a singular, authoritative record of users' permissions and entitlements. Consequently, administrators can confidently modify a user's privileges, knowing that these adjustments will be applied consistently throughout the entire network.
* **Improved user productivity:** Users are relieved from recalling multiple passwords to access network resources.
* **Simpler administration:** Tasks are seamlessly integrated into routine maintenance, utilizing the same tools for other administrative duties.
## Security Risks of Single Sign-on
Conversely, SSO may only be ideal for some use cases. Some thorny issues include managing costs, control and security, etc. It can also be a single point of failure.
The Achilles heel of this authentication procedure is that users' credentials are vulnerable to compromise. An attacker can access all or most of the resources and applications on the network. Authentication exposures such as "[Sign In with Apple](https://portswigger.net/daily-swig/sign-in-with-apple-vulnerability-find-earns-100k-bug-bounty)" and [Microsoft OAuth flaws](https://www.darkreading.com/cloud-security/azure-ad-log-in-with-microsoft-authentication-bypass-affects-thousands/) allow attackers to pose as target users and sign into a site or web service.
As a countermeasure, the majority of security professionals recommend the incorporation of [two-factor authentication](https://duo.com/product/multi-factor-authentication-mfa/two-factor-authentication-2fa/) (2FA) or [multifactor authentication](https://en.wikipedia.org/wiki/Multi-factor_authentication/) (MFA) into any single sign-on setup. 2FA or MFA requires users to provide at least one authentication element alongside a password, such as a code delivered to a mobile device, a fingerprint, or an ID card. Because hackers do not easily pilfer these supplementary credentials, implementing MFA can significantly reduce the risks associated with compromised credentials in SSO.
In addition, requiring users to set long and complex passwords and rigorously encrypting and securing those passwords wherever they are stored helps prevent hackers from gaining access.
## Types of Single Sign-on
It's essential to understand some standard SSO protocols. A few examples of these protocols are:
* **Security Assertion Markup Language (SAML):** [SAML](https://en.wikipedia.org/wiki/Security_Assertion_Markup_Language//) is a basic SSO protocol. It is an open standard that exchanges authentication and authorization information between different parties, specifically between an [identity provider](https://en.wikipedia.org/wiki/Identity_provider/) and a service provider. It has now become an indispensable standard and is adopted by numerous application providers to verify authentication requests.
* **Open Authorization(OAuth):** [OAuth](https://en.wikipedia.org/wiki/OAuth//) delegates access by enabling internet users to authorize websites or applications to access their information or data on platforms without disclosing their passwords.
* **OpenID Connect (OIDC):** [OpenID connect](https://auth0.com/docs/authenticate/protocols/openid-connect-protocol/) is an open authentication protocol that enables users to be authenticated by collaborating websites, referred to as relying parties, through a third-party identity provider (IDP) service. This eliminates the necessity for website owners to develop their login systems while enabling users to access multiple independent websites without managing separate identities and passwords. Users establish accounts by choosing an OpenID identity provider, which they subsequently utilize to log in to any website that supports OpenID authentication.
* **Kerberos:** [Kerberos](https://en.wikipedia.org/wiki/Kerberos_(protocol)/) is a third-party network authentication technology that uses shared secret keys to authenticate a user securely in an unprotected network. It was designed primarily for a client-server model, and it supports mutual authentication, which means that both the user and the server can verify each other's identities. Kerberos protocol messages are secure from eavesdropping and replay attacks.

## Workflow of Single Sign-on
An identity provider (IDP) creates an authentication server that verifies user identity and provides an encrypted access token to confirm their identity. Users are redirected to the IDP when they first try to gain access to an app or website.
For example, a company chooses [Slack](https://slack.com//) for team collaboration and [Okta](https://www.okta.com//) for identity management. Users must go through Okta's authentication process when they want to access Slack. They may enter their corporate credentials or use a multifactor authentication method supported by Okta. Okta verifies the user's credentials against the user store and makes an authentication decision by starting an SSO session if they are valid. Along with this decision, Okta may provide Slack with additional user attributes such as username, email address, etc. These attributes help Slack personalize the user's experience and enforce any access control policies the organization sets.
While Slack relies on Okta for authentication and user attributes, it may still maintain a local account for the user. This local account contains user-specific data within the Slack platform, such as chat history.
Slack workshop's workspace
This is a free account. Click on upgrade for SAML authentication. To follow up the rest of the authentication process, check [Okta/Slack authentication process](https:/https://saml-doc.okta.com/SAML_Docs/How-to-Configure-SAML-2.0-for-Slack.html/).
The system authenticates the user's session and logs them into their Slack account.
Image source: [Helpjuice](https://help.helpjuice.com/en_US/authentication/single-sign-on-authentication/)
Here is a simple breakdown of an SSO workflow:
1. The user requests access from a website or application.
2. The application or website redirects the user to the identity provider's login page.
3. The user enters their login credentials.
4. If the credentials are valid, the identity provider verifies the user and passes an authentication token to the SSO server.
5. The SSO server returns the authentication token to the application or website.
6. The application permits access to the user and stores the session for future use.
## Prerequisites for Implementing Single Sign-on
To set up an SSO profile, you must gather some basic configuration from your IDP's support team or documentation. Consider the following prerequisites if all your users will sign in through one IDP using SAML:
* Sign-in page URL: This is a critical component known as the SSO URL or [SAML 2.0 Endpoint](https://www.ibm.com/docs/en/tfimbg/6.2.2.6?topic=urls-saml-20-endpoints/) (HTTP). It's the gateway where users sign in to your IDP.
* Sign-out page URL: This is where the user lands after exiting the Google app or service.
* Certificate: The [X.509 PEM](https://en.wikipedia.org/wiki/X.509/) certificate from your IDP is critical to the setup process.
* Change password URL: This is the page where users will change their passwords instead of changing them with IDP.
## Implementing Single Sign-on in Your Organization
You can set up SSO for your organization using Google as a service provider. To configure a profile for your users through one IDP using SAML protocol, do this:
1. Create an administrator account with Google and sign in to the Google Admin console.
2. Go to Menu>Security>Authentication>SSO with third-party IDP in the Admin console.
3. In the Third-party SSO profile for your organization, click Add SSO profile.
4. Check the Setup SSO with the third-party identity provider box.
Using the information in the prerequisites box, fill in the following for your identity provider:
* Enter the URLs for your IDP's sign-in and sign-out pages.
**Note:** Use HTTPS to enter all URLs, such as https://sso.example.com.
* After selecting Upload certificate, find and upload the X.509 certificate your IDP sent you.
* Choose whether to include a domain-specific issuer in the Google SAML request.
* If you have many domains using SSO with your IDP, use a domain-specific issuer to determine which domain is making the SAML request.
* If checked, Google sends an issuer-specific one to your domain. For instance, if example.com is your principal Google Workspace domain name, you can use google.com/a/example.com.
* If unchecked, Google sends the standard issuer in the SAML request (Google.com).
* Enter your IDP's change password URL here. Visitors will visit this URL (instead of the Google Change password page)

## Understanding Single Sign-on Protocols
Some SSO protocols and their pathway include:
### SAML
SAML is a standardized option for implementing SSO. This protocol uses [XML](https://en.wikipedia.org/wiki/XML/) files to exchange data about the user, the IDP, and the service provider. SAML's key components are assertion, identity provider, and the service provider.
**SAML Pathway**: In an application employing single sign-on, when a user asks for a request to a resource, the application, acting as the service provider, verifies the user's authorization by consulting the identity provider. The IDP, in turn, authenticates the user's identity and issues an assertion confirming the user's access privileges for the requested resource.
**SAML Use Cases:** SAML can enable SSO transactions. In an enterprise login SSO, users can employ SAML to access multiple applications without requiring a separate login. Additionally, in a federated SSO environment, users from one organization can utilize their credentials to access the resources another organization provides using SAML.
SAML can also enforce access control lists ([ACL](https://www.okta.com/identity-101/access-control-list//)) and facilitate ACL transactions. In this scenario, a user seeks access to a secure resource, and the SAML service renders an authorization verdict. Authentication is typically separate from this particular use case.
### OpenID Connect
OIDC is an authentication protocol that extends the OAuth 2.0 framework to provide a secure and dependable way to authenticate users across multiple apps. OIDC uses a JSON web token ([JWT](https://en.wikipedia.org/wiki/JSON_Web_Token/)) to exchange information between identity and service providers. JWTs are encrypted, digitally signed tokens that contain assertions about the user's identity.
**OIDC Pathway:** When a user requests access to a program, the application directs the request to the IDP for authentication. Once the authentication is complete, the IDP will prompt the user to grant access to the specified application. The IDP then generates an ID token containing identification information that the application can readily use. Subsequently, the IDP redirects the user to the program, allowing them to access it without the need to enter their credentials again.
**OpenID Connect Use Cases:** OIDC enables secure authentication, authorization, and API access. Some of the OpenID use cases include:
* **Implicit flow** is typically employed for single-page applications, where tokens are directly provided to the application via a redirect.
* **Authorization Code flow** is most commonly used in native, single-page, and mobile web apps. It's designed for applications that are not reliable for storing sensitive data. This flow utilizes cryptographically signed JWT tokens, and user data remains undisclosed to the application.
* **The hybrid approach** merges the flows mentioned above. Initially, it issues an ID token to the application via a redirect URL. Subsequently, the application exchanges the ID Token for a temporary access token.
### LDAP/AD
The LDAP allows users to access a credentials directory. Communication takes place via the LDAP Data Interchange Format ([LDIF](https://en.wikipedia.org/wiki/LDAP_Data_Interchange_Format/)). An LDAP directory can be shared across several applications. Integrating LDAP with Active Directory ([AD](https://en.wikipedia.org/wiki/Active_Directory/)) enables the central AD server to store user identities. Subsequently, applications can direct authentication requests to the LDAP/AD server.
**LDAP Pathway:** An application sends a request to access data stored in an LDAP database. The application provides the LDAP server user credentials, username, and password. Subsequently, the LDAP server compares the user identity information stored in the AD or LDAP database with the credentials provided by the user. This user identity information, including phone numbers, addresses, or group participation, serves as a unique identifier. If the credentials provided match the stored user ID, LDAP grants access to the requested data. However, incorrect credentials will deny access to LDAP, ensuring access control measures are upheld.
**LDAP/AD Use Cases:** Because of its open and cross-platform nature, LDAP is applicable across many directory service providers and applications. LDAP is typically a centralized repository for credentials like usernames and passwords.
LDAP authentication is compatible with various widely used applications, including [OpenVPN](https://openvpn.net//), [Docker](https://www.docker.com//), [Jenkins](https://www.jenkins.io//), and [Kubernetes](https://kubernetes.io//). System administrators leverage LDAP's SSO functionality to efficiently oversee LDAP database access across multiple applications.
## Selecting the Appropriate SSO Protocol
The choice of authentication protocol plays an important role when distinguishing between enterprise and consumer apps. Enterprise applications frequently use SAML because of its comprehensive support and integration capabilities with enterprise identity providers and its ability to handle intricate authentication circumstances. In contrast, [OAuth 2.0](https://oauth.net/2///) and OIDC are more suited for consumer-facing apps, as they are adaptable and compatible with mobile and online applications.
The specific authentication and authorization requirements are the foundational bedrock for SAML, OIDC, and OAuth2.0. If the primary need is authentication, which involves verifying user identification, SAML or OIDC are typically the preferred options. OIDC, built on top of OAuth 2.0, provides an additional identity layer to OAuth's authorization capabilities. Programs use OAuth 2.0 to access user resources while keeping user passwords uncompromised.
Regarding application and platform compatibility, ensuring that the SSO protocols align with your current infrastructure and the applications you plan to integrate is crucial. While SAML may be broadly supported by some legacy or enterprise systems, modern applications often favor OAuth 2.0 and OIDC due to their API-friendly nature and ability to enhance user experience, especially in web and mobile environments.
Additionally, you should future-proof your application ecosystem. Are you migrating to cloud-based services, APIs, and mobile apps? In cloud and mobile applications, OAuth 2.0 and OIDC may provide greater flexibility and are generally considered more forward-looking.
## Final Thoughts
Single sign-on is an authentication protocol that enables users to log in to websites or applications without re-entering their passwords. SAML, OIDC, and OAuth are some of the different authentication mechanisms that offer approaches to this process. This article has discussed how to implement SSO in your organization and the factors to consider when choosing the appropriate SSO protocol.

It helps to test hypotheses about differences among group means and is especially useful when comparing multiple groups.
Key Concepts:
1. Groups or Levels: These are the different categories or treatments being compared. For example, if you're testing the effect of different diets on weight loss, each diet is a group.
2. Within-Group Variance: This is the variability of data points within each group. It measures how much the data points in a single group deviate from the group mean.
3. Between-Group Variance: This is the variability between the group means. It measures how much the group means differ from the overall mean.
4. F-Statistic: ANOVA produces an F-statistic, which is a ratio of the between-group variance to the within-group variance. A higher F-statistic suggests a greater likelihood that the observed differences between group means are real and not due to random chance.
Steps in ANOVA:
Formulate Hypotheses:
* Null Hypothesis (H₀): The means of all groups are equal.
* Alternative Hypothesis (H₁): At least one group mean is different from the others.
* Calculate Group Means and Overall Mean.
* Calculate Within-Group and Between-Group Variance.
* Compute the F-Statistic:
`F = Between-Group Variance / Within-Group Variance`
* Compare the F-Statistic to a Critical Value: This critical value is determined by the degrees of freedom and the chosen significance level (often 0.05). If the F-statistic is larger than the critical value, reject the null hypothesis.
Assumptions of ANOVA:
- Independence: The samples must be independent of each other.
- Normality: The data in each group should be approximately normally distributed.
- Homogeneity of Variances: The variance among the groups should be approximately equal.
Types of ANOVA:
1. One-Way ANOVA: Used when comparing the means of three or more independent groups based on one factor.
2. Two-Way ANOVA: Used when comparing the means based on two factors and can also test for interaction effects between the factors.
3. Repeated Measures ANOVA: Used when the same subjects are used for each treatment (e.g., a longitudinal study).
Example Scenario:
We have test scores from three different teaching methods. We want to determine if there is a statistically significant difference between the means of these three groups.
```python
import numpy as np
# Example data: test scores from three different teaching methods
group1 = np.array([85, 90, 88, 92, 87])
group2 = np.array([78, 85, 80, 83, 82])
group3 = np.array([90, 92, 95, 91, 89])
# Combine all groups into a single array
all_data = np.concatenate([group1, group2, group3])
# Calculate group means and overall mean
mean_group1 = np.mean(group1)
mean_group2 = np.mean(group2)
mean_group3 = np.mean(group3)
mean_overall = np.mean(all_data)
# Calculate sum of squares between groups (SSB)
ssb = (len(group1) * (mean_group1 - mean_overall)**2 +
len(group2) * (mean_group2 - mean_overall)**2 +
len(group3) * (mean_group3 - mean_overall)**2)
# Calculate sum of squares within groups (SSW)
ssw = (np.sum((group1 - mean_group1)**2) +
np.sum((group2 - mean_group2)**2) +
np.sum((group3 - mean_group3)**2))
# Calculate degrees of freedom
df_between = 3 - 1 # Number of groups - 1
df_within = len(all_data) - 3 # Total number of observations - Number of groups
# Calculate mean squares
ms_between = ssb / df_between
ms_within = ssw / df_within
# Calculate the F-statistic
f_statistic = ms_between / ms_within
# Display results
print("ANOVA Results")
print("=============")
print(f"Sum of Squares Between (SSB): {ssb:.2f}")
print(f"Sum of Squares Within (SSW): {ssw:.2f}")
print(f"Degrees of Freedom Between: {df_between}")
print(f"Degrees of Freedom Within: {df_within}")
print(f"Mean Square Between (MSB): {ms_between:.2f}")
print(f"Mean Square Within (MSW): {ms_within:.2f}")
print(f"F-Statistic: {f_statistic:.2f}")
# To determine the p-value, we need to use the F-distribution
from scipy.stats import f
# Calculate the p-value
p_value = 1 - f.cdf(f_statistic, df_between, df_within)
print(f"P-Value: {p_value:.4f}")
# Conclusion
alpha = 0.05
if p_value < alpha:
print("Reject the null hypothesis: There is a significant difference between the group means.")
else:
print("Fail to reject the null hypothesis: There is no significant difference between the group means.")
```
output:
```python
ANOVA Results
=============
Sum of Squares Between (SSB): 252.13
Sum of Squares Within (SSW): 79.60
Degrees of Freedom Between: 2
Degrees of Freedom Within: 12
Mean Square Between (MSB): 126.07
Mean Square Within (MSW): 6.63
F-Statistic: 19.01
P-Value: 0.0002
Reject the null hypothesis: There is a significant difference between the group means.
```
**Explanation:**
1. Data Preparation: Three groups of test scores are defined and combined into a single array.
2. Mean Calculation: Calculate the means for each group and the overall mean.
3. Sum of Squares Calculation:
4. SSB (Sum of Squares Between): Measures the variance between the group means and the overall mean.
5. SSW (Sum of Squares Within): Measures the variance within each group.
6. Degrees of Freedom: Calculated for both between-group and within-group variations.
7. Mean Squares: Compute the mean squares by dividing the sum of squares by the respective degrees of freedom.
8. F-Statistic: Ratio of the mean square between groups to the mean square within groups.
9. P-Value: Using the F-distribution to determine the significance of the F-statistic.
**Conclusion: Based on the p-value, decide whether to reject the null hypothesis.**

All hooks are recognizable by the use prefix. For example, _useState_ is a hook.
React Hooks are functions that let you use state and other React features in functional components.
Introduced in React 16.8, hooks provide a way to manage component logic in a more concise and reusable way compared to class components.
For now, remember that hooks have rules that we need to abide by:
> Hooks can only be called from the top level of a functional component.
> Hooks can’t be called from inside loops or conditions.
## Commonly Used Hooks
1. useState: Manages state within functional components.
2. useEffect: Handles side effects like data fetching, subscriptions, or manually changing the DOM.
3. useContext: Provides a way to use React's Context API in functional components.
4. useReducer: Manages complex state logic and is an alternative to useState.
5. useRef: Accesses DOM elements directly or persists mutable values across renders.
6. useMemo: Memoizes expensive calculations.
7. useCallback: Memoizes callback functions to prevent unnecessary re-renders.
8. useLayoutEffect: Similar to useEffect, but it fires synchronously after all DOM mutations.
9. useImperativeHandle: Customizes the instance value that is exposed when using ref in parent components.
Well go through afew of the hooks.
1. _useState_: Manages state within functional components.
In the example above; 'useState' initializes state and returns an array with the current state value and a function to update it.
2. _useEffect_: Handles side effects like data fetching, subscriptions, or manually changing the DOM.
The example above is a section of the useEffect in a react file when collecting data.Here is how the whole file with the use Effectlooks like.
These are the most used hooks in react.

[Responsive web design](https://developer.mozilla.org/en-US/docs/Learn/CSS/CSS_layout/Responsive_Design) plays an important role in web development today, it is used to ensure websites created are accessible and user-friendly.
While most people are familiar with the fundamentals of responsive web design,understanding more advanced strategies can enhance their usefulness and quality.
This article will cover a few of these advanced techniques, focusing on dynamic typography, fluid media handling, retina-ready graphics, responsive navigation, conditional asset loading, and accessibility in responsive design.
## Dynamic Typography
In web design, typography plays an important role by influencing a website's legibility and user experience. With the increase of different devices and screen sizes, the typography across various devices must remain legible and visually appealing to users.
Dynamic typography simply refers to the ability of text on a website to adjust according to the screen dimensions and resolution of the device. This adjustment ensures that text remains clear and visually appealing, whether the user is viewing the website from a desktop computer, tablet, or smartphone.
This technique uses units such as viewport width (`vw`) and root em (`rem`) to create a responsive and scalable typography system that ensures readability across devices.
We can implement dynamic typography using `CSS` techniques to create responsive text styles that adjust to diverse screen sizes and user preferences. This can be achieved through the following methods:
**Viewport Units**: This involves using viewport units such as `vw` (viewport width) and `vh` (viewport height) to adjust font sizes to the size of the viewport. For example, setting `font-size: 3vw;` will adjust the font size to 3% of the viewport's width.
```html
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Viewport Units</title>
<style>
body {
font-size: 3vw;
background-color: black;
}
h1 {
color: white;
text-align: center;
}
p {
color: white;
font-family: verdana;
font-size: 20px;
</style>
</head>
<body>
<h1>Responsive Font Size</h1>
<p>This text will adjust its size based on the width of the viewport.</p>
</body>
</html>
```
In the code above, the `<meta name="viewport" content="width=device-width, initial-scale=1.0" />` tag is added in the `head` section of the HTML. The tag instructs the browser to match the viewport's width to the device's width and to scale the page to 1:1, ensuring it appears well on the device.
In the CSS section of the code, the font size of the body element is set to `3vw`, meaning it adjusts to 3% of the viewport's width, making it responsive to the viewport's width.
The font size adjusts accordingly as the width of the viewport changes when resizing the browser window or on different devices.
The HTML content of the code includes a `h1` heading with the text "Responsive Font Size" and a `p` tag with the text "This text will adjust its size based on the width of the viewport."
The image above displays the standard code output size when viewed in a browser.
As the viewport width changes, the font size of the text in the `p` and` h1` tags adjusts to match the viewport's width, as illustrated in the image below.
This scaling ensures readability across various screen sizes and devices, enhancing user experience.
**Media Queries**: [Media queries](https://developer.mozilla.org/en-US/docs/Learn/CSS/CSS_layout/Media_queries) can be used to set various styles depending on the size of the screen. i.e., you can specify varying font sizes for mobile devices, tablets, and desktop screens.
In the example below, we will show how media queries can be implemented in a simple project.
Here is the HTML;
```html
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<link rel="stylesheet" href="style.css" />
<title>Login Form</title>
</head>
<body>
<div class="container">
<h2>Login</h2>
<form>
<input type="text" placeholder="Username" required />
<input type="password" placeholder="Password" required />
<button type="submit">Login</button>
</form>
</div>
</body>
</html>
```
Here is the CSS;
```css
body {
font-family: Arial, sans-serif;
background-color: #000000;
margin: 0;
padding: 0;
}
.container {
max-width: 400px;
margin: 100px auto;
background-color: #fff;
padding: 20px;
border-radius: 5px;
box-shadow: 0 2px 5px rgba(0, 0, 0, 0.1);
}
h2 {
text-align: center;
margin-bottom: 20px;
}
form {
display: flex;
flex-direction: column;
}
input[type="text"],
input[type="password"],
button {
padding: 10px;
margin-bottom: 10px;
border: 1px solid #ccc;
border-radius: 3px;
box-sizing: border-box;
}
button {
background-color: #007bff;
color: #fff;
cursor: pointer;
}
/* Media queries for responsive design */
@media (max-width: 767px) {
.container {
max-width: 300px;
margin-top: 50px;
}
}
@media (min-width: 768px) and (max-width: 1023px) {
.container {
max-width: 400px;
}
}
@media (min-width: 1024px) {
.container {
max-width: 600px;
}
}
```
The code above uses CSS media queries to target the .container class, applying specific styles based on the width of the viewport.
Mobile view;
* The `max-width` 767px media query targets screens with a maximum width of 767 pixels. It adjusts `.container` to 300px width and sets a `margin-top` of 50px for smaller screens like mobile devices.
Tablet view;
* The `min-width` 768px and `max-width` 1023px media query targets screens with a width between 768 pixels and 1023 pixels and sets `.container` width back to 400px for bigger screens, such as tablets.
Desktop view;
* The `min-width` 1024px media query targets screens with a minimum width of 1024 pixels and expands `.container` to 600px for desktop and laptop screens.
Using these media queries, the login form's container adjusts its width and layout according to the user's screen size, ensuring a responsive and user-friendly design that works well on different devices and screen resolutions.
<CTA_Middle_Design />
**Fluid Typography**: [Fluid typography](https://blog.openreplay.com/doing-fluid-typography-for-responsive-designs/) techniques can be used to create scalable text that adjusts smoothly across various screen sizes. This can be achieved by combining viewport units, media queries, and the CSS `calc()` function.
```css
body {
font-size: calc(16px + 0.5vw);
}
```
Example;
```html
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Fluid Typography Example</title>
<style>
body {
font-size: calc(16px + 0.5vw);
background-color: black;
color: white;
}
</style>
</head>
<body>
<h1>Fluid Typography Example</h1>
<p>This is an example of fluid typography.</p>
</body>
</html>
```
Output;
In the example above, the `font-size` property within the `body` selector uses the `calc()` function to set the font size relative to the viewport width (`vw`). It begins at 16 pixels (`16px`) and increases by half of the viewport width (`0.5vw`).
When you open this HTML file in a web browser and resize the window, you'll observe the text size adapting dynamically, ensuring it remains legible across different screen sizes.
**Line Height**: This is done by modifying the line height according to the font size to ensure readability and visual appeal across various devices.
```css
body {
line-height: 1.5;
}
```
Let's use it in an example;
```html
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Line Height Example</title>
<style>
body {
background-color: black;
font-family: "Roboto", sans-serif;
color: white;
font-size: 16px;
line-height: 1.5;
}
</style>
</head>
<body>
<h1>Line Height Example</h1>
<p>This is an example of text with adjusted line height.</p>
</body>
</html>
```
Output;
In the example above, `line-height: 1.5;` in the `body` selector sets the line height of the text within the `body` element to 1.5 times the font size. This increases the spacing between lines, enhancing readability.
**Fallback Fonts**: To achieve consistent typography across platforms, you can use fallback font families as backups in case the primary font isn't available on the user’s device.
```css
body {
font-family: "Roboto", sans-serif;
}
```
The code sets the font family for the text in the `body` element to "Roboto" as the preferred font, with a fallback to a sans-serif font in case "Roboto" is unavailable.
Combining these methods above, you can create a responsive typography system that effectively adjusts to different screen sizes and enhances the user experience.
## Fluid Images and Videos
It is very important in web design to ensure that images and videos retain quality across various devices and screen sizes. A major challenge in responsive design is maintaining the aspect ratio of images and videos.
When a website is viewed on different devices with different screen sizes, the content needs to scale proportionally to use the available space effectively without reducing the quality or causing distortion. We can accomplish this by using the powerful properties of CSS to achieve fluidity.
In a fluid layout, elements can adapt to different viewport dimensions without changing their appearance or functionality.
An important tip for images is to use the CSS property `max-width: 100%;` in combination with `height: auto;.` This ensures that images resize proportionally based on the dimension of their container.
This property restricts the width of the image to fit within the available space without exceeding it, while `height: auto;` automatically adjusts the height of the image to preserve its aspect ratio.
This ensures that images scale smoothly across various screen sizes to prevent overflow or pixelation on smaller screens.
```css
img {
max-width: 100%;
height: auto;
}
```
The code above makes images on the webpage responsive by setting their maximum width to 100% of the container's width, allowing it resize proportionally. The `height: auto;` property maintains the image's aspect ratio, preventing distortion when resized.
You can make videos responsive by using the [aspect-ratio](https://developer.mozilla.org/en-US/docs/Web/CSS/aspect-ratio) property in CSS. This is done by specifying the required aspect ratio. For example, using 16:9 for widescreen videos makes the video element adjust its dimensions to maintain the correct aspect ratio regardless of the viewport size.
This makes the videos consistent and not stretched on devices with different screen dimensions.
```css
.video-container {
aspect-ratio: 16/9; /* Or any other desired aspect ratio */
}
```
The code above creates a class called `.video-container` with a 16:9 aspect ratio. It adjusts the container's height relative to its width, preserving the aspect ratio and ensuring a distortion-free display of videos or content inside.
## Retina-Ready Graphics
Ensuring your website has high-quality graphics is extremely important nowadays. Techniques such as the `srcset` attribute in HTML allow us to produce different image resolutions based on the device's pixel density, thus creating sharp visuals.
Retina-ready graphics are images designed to maintain sharpness on devices with high pixel density.
To achieve clear graphics on such screens, we can use the following methods:
* Select the right file formats that support high-quality visuals. For pictures, it is recommended to use [JPEG](https://developer.mozilla.org/en-US/docs/Glossary/JPEG) formats with high compression settings to reduce the size of the file without reducing the quality.
* Use [PNG]() or [SVG](https://developer.mozilla.org/en-US/docs/Web/SVG) formats for graphics to maintain the quality.
* Use vector graphics like SVG for your icons, logos, and illustrations to maintain quality.
* Use high-resolution images with double the resolution required for standard displays allows the image to retain its sharpness.
* Use CSS media queries to detect Retina displays and also serve higher-resolution graphics accordingly. You can achieve this by specifying different image URLs based on the device's pixel density.
By using these methods, we can ensure that graphics are of high quality on Retina displays, thus enhancing the overall quality of the website.
## Conditional Asset Loading
We can optimize the performance of responsive designs via [lazy loading](https://developer.mozilla.org/en-US/docs/Web/Performance/Lazy_loading) and conditional asset loading. Lazy loading refers to the loading of non-critical resources that are loaded only when they are needed. Lazy loading is mainly used in some user interactions such as scrolling and navigation.
You can implement lazy loading by using the `loading` attribute:
```html
<img loading="lazy" src="image.jpg" alt="..." />
<iframe loading="lazy" src="video-player.html" title="..."></iframe>
```
In the code above, the HTML elements use `lazy loading` for improved performance:
The `img` tag uses `loading="lazy"` to load the image only when it's about to enter the viewport, reducing initial load times and saving bandwidth.
The `iframe` tag uses `loading="lazy"` to lazy load the content. This can be helpful for large videos, which can be loaded only when needed, enhancing the overall page loading speed and user experience.
## Accessibility in Responsive Design
In creating accessible websites, people with disabilities or different browsing methods should also be considered.
There are [guidelines](https://www.w3.org/WAI/standards-guidelines/wcag/) published by the [Web Accessibility Initiative (WAI)](https://www.w3.org/WAI/) of the World Wide Web Consortium (W3C) that helps people with:
* Attention or anxiety disorders.
* Short-term memory, or people who multitask.
* Lower technological literacy.
* Poor wireless reception.
* Motor control issues.
To create responsive websites that are inclusive to meet the needs of the people mentioned above, we can use the following methods:
* Creation of content that can be presented in different ways without losing information or structure. For example, provide responsive layouts, with a single-column mobile design.
* Creation of content that does not distract people with attention deficit disorders. This provides access to people with cognitive disabilities by enabling them to focus on the main purpose of the content.
* Create user-friendly website navigation by incorporating title tags for quick understanding, using descriptive labels to identify specific components, and clear headings to organize content into chapters, sections, and subsections. This enhances navigation and improves comprehension for users.
## Conclusion
The article talked about the importance of Responsive Web Design (RWD) in creating accessible and user-friendly websites. It explored advanced techniques such as dynamic typography, fluid media handling, retina-ready graphics, responsive navigation, conditional asset loading, and accessibility methods that can enhance the quality and functionality of responsive designs. Through the mastery and combination of the techniques mentioned above, developers can create visually appealing and responsible websites.

1,893,161 | How to use Git | Commands and their Explanations | This guide walk you through how to use git, covering every command you'll need to navigate your way... | 27,838 | 2024-06-19T05:42:07 | https://dev.to/nnnirajn/how-to-use-git-commands-and-their-explanations-1bj7 | git, github, gitlab, programming | This guide walk you through how to use git, covering every command you'll need to navigate your way through version control like a pro. Whether you're a newcomer or a seasoned web developer, this post will provide valuable insights to enhance your workflow.
## What is Git?
To start things off, let's address the elephant in the room. What exactly is Git? Git is a distributed version control system. Unlike centralized version control systems, Git doesn't rely on a single repository to store all versions of your project. Instead, every developer has a complete copy on their own machine. This makes Git incredibly fast, scalable, and ideal for collaborating with teams of all sizes.
Before diving into the commands, let’s get Git up and running on your system.
### Installation
1. **Windows:**
+ Download the Git installer from [Git's official website](https://git-scm.com/).
+ Run the installer, and follow the on-screen prompts. Feel free to use the default settings.
2. **macOS:**
+ Use Homebrew to install Git. Open a terminal and enter:
```bash
brew install git
```
3. **Linux:**
+ Use your package manager. For Ubuntu/Debian, run:
```bash
sudo apt-get install git
```
### Configuration
Once installed, it's time to set up your identity. This information will be used in commit messages:
```bash
git config --global user.name "Your Name"
git config --global user.email "yourname@example.com"
```
To confirm your configurations:
```bash
git config --list
```
---
## Starting a Git Repository
Now that you have Git set up, let's start using it.
### Initializing a Repository
To create a new Git repository, navigate to your project directory and run:
```bash
git init
```
This command sets up a new repository, creating a .git directory in your project.
### Cloning an Existing Repository
If you want to contribute to an existing project, you can clone it to your local machine:
```bash
git clone https://github.com/user/repository.git
```
This creates a copy of the specified repository on your machine.
---
## Basic Commands
With the repository in place, let's explore some basic commands that you'll frequently use.
### Checking the Status
To view the status of your working directory and staging area, run:
```bash
git status
```
This command shows which files are staged, modified, or untracked.
### Adding Changes
When you make changes to files, you need to add them to the staging area before committing them:
```bash
git add filename
```
To add all files at once:
```bash
git add .
```
### Committing Changes
After staging your changes, you'll need to commit them:
```bash
git commit -m "Brief message describing the changes"
```
This command saves your changes in the repository. The message should be concise yet descriptive.
### Viewing Commit History
To see the commit history, use:
```bash
git log
```
This command displays all past commits, along with their messages. For a more compact view:
```bash
git log --oneline
```
---
## Branching and Merging
Branching is one of Git's most powerful features, allowing you to work on different tasks simultaneously.
### Creating a Branch
To create a new branch:
```bash
git branch new-branch
```
### Switching Branches
To switch to another branch:
```bash
git checkout new-branch
```
### Merging Branches
Once you're done working on a branch, you can merge it back into the main branch:
```bash
git checkout main
git merge new-branch
```
### Deleting a Branch
After merging, you may want to delete the branch:
```bash
git branch -d new-branch
```
---
## Remote Repositories
Collaborating with others requires interacting with remote repositories.
### Adding a Remote
To add a remote repository:
```bash
git remote add origin https://github.com/user/repository.git
```
### Viewing Remotes
To list your remote repositories:
```bash
git remote -v
```
### Pushing Changes
To push your changes to a remote repository:
```bash
git push origin branch-name
```
If it's your first time pushing a branch:
```bash
git push -u origin branch-name
```
### Pulling Changes
To update your local repository with changes from a remote repository:
```bash
git pull origin branch-name
```
---
## Advanced Commands
Let's dive deeper into some advanced commands that offer more control over your repository.
### Stashing Changes
If you need to switch branches but aren't ready to commit your changes, you can stash them:
```bash
git stash
```
To reapply the stashed changes:
```bash
git stash apply
```
### Viewing Diffs
To see changes between commits or working trees:
```bash
git diff
```
### Resetting Commits
To undo a commit and move the changes back to the staging area:
```bash
git reset HEAD~1
```
### Reverting Commits
To create a new commit that undoes a previous commit:
```bash
git revert commit-id
```
### Rebasing Branches
To reapply commits on top of another base tip:
```bash
git rebase branch-name
```
---
## Solving Conflicts
When multiple changes affect the same part of a file, a conflict occurs. Git provides tools to resolve these conflicts.
### Conflict Indicators
When a conflict happens, the affected file contains conflict markers:
```
<<<<<<< HEAD
Your changes
=======
Changes from the other branch
>>>>>>>
```
You'll need to edit the file to mark the resolved content.
### Adding and Committing Resolved Files
After resolving conflicts, mark the file as resolved:
```bash
git add filename
```
Then, commit the resolution:
```bash
git commit
```
---
## Git Workflows
Understanding different workflows can make managing your projects easier.
### Feature Branch Workflow

[Tanstack Router](https://tanstack.com/router/v1) is a modern and scalable routing solution for React, created by *Tanner Linsey(creator of react-query)*. Its [core objective](https://tanstack.com/router/v1/docs/framework/react/decisions-on-dx#1-why-is-the-routers-configuration-done-this-way) centers around type-safety and developer productivity.
The core philosophy behind TanStack Router is simply the full utilization of Typescript for web routing. Developers should be able to write type-safe routes, actions, and loaders, which will result in fewer runtime errors. This provides a cohesive environment where routes are well-defined type-safe contracts instead of just navigation pathways in an application.
On the contrary, React Router is built on the philosophy of simplicity and flexibility. It aims to make routing implementation in React applications simple. Unlike TanStack Router, React Router takes an unopinionated and incremental adoption approach, allowing developers to start simple and gradually add more advanced routing techniques as the need arises.
The following table from the [TanStack Router documentation](https://tanstack.com/router/latest/docs/framework/react/comparison) compares TanStack Router and React Router:

## Build a Single Page Application with React and TanStack Router
In this section, we will build a single-page application in React that retrieves data from an API and runs in the browser. Routing will be done using TanStack Router, and Tailwind-CSS will be used for styling. The application you'll build will show information about popular movies via the [TMDb API](https://developer.themoviedb.org/reference/search-movie).
Building this project from scratch will help us understand how to use the TanStack Router from a hands-on perspective, which is crucial when learning a new technology.
### Prerequisite
- Working knowledge of React and Typescript
- Familiarity with [Tailwind CSS](https://tailwindcss.com/)
- Code Editor — such as VSCode
- [Node.js Latest LTS](https://nodejs.org/en) installed on your computer.
- TMDb [API key](https://developer.themoviedb.org/reference/search-movie)
The complete code for this project can be found on *[GitHub](https://github.com/wisdomekpotu/tanstack-movieapp)*.
### Project Demo
### Creating a Vite App and Installing Dependencies
We will use [vite](https://vitejs.dev/) to create our React app.
```bash
npm create vite@latest movie-app --template react-ts
npm install
```
The preceding command allows you to scaffold a react project with Typescript using Vite. We use Typescript because our routing will be done via Tanstack Router, which is *100% type-safe*.
Next, install the following dependencies; they will be utilized for the project.
```bash
npm install -D zod tailwindcss postcss autoprefixer
npx tailwindcss init -p
```
In the preceding command, you installed [zod](https://zod.dev/?id=introduction), [tailwindcss](https://tailwindcss.com/docs/guides/vite) and its peer dependencies. The `npx tailwindcss init -p` command generates the `tailwind.config.js` and `postcss.config.js` files, which will be used to configure tailwind. Also, the *zod* library will validate and infer Typescript type(s) for routes.
After running the above commands, the following `package.json` will be created for the project.
```json
{
"name": "movie-app",
"private": true,
"version": "0.0.0",
"type": "module",
"scripts": {
"dev": "vite",
"build": "tsc && vite build",
"lint": "eslint . --ext ts,tsx --report-unused-disable-directives --max-warnings 0",
"preview": "vite preview"
},
"dependencies": {
"react": "^18.2.0",
"react-dom": "^18.2.0"
},
"devDependencies": {
"@types/react": "^18.2.66",
"@types/react-dom": "^18.2.22",
"@typescript-eslint/eslint-plugin": "^7.2.0",
"@typescript-eslint/parser": "^7.2.0",
"@vitejs/plugin-react": "^4.2.1",
"autoprefixer": "^10.4.19",
"eslint": "^8.57.0",
"eslint-plugin-react-hooks": "^4.6.0",
"eslint-plugin-react-refresh": "^0.4.6",
"postcss": "^8.4.38",
"tailwindcss": "^3.4.3",
"typescript": "^5.2.2",
"vite": "^5.2.0",
"zod": "^3.22.4"
}
}
```
Now, let's configure tailwind via the `tailwind.config.js` and `index.css` files, respectively.
Enter the following code:
`tailwind.config.js`:
```javascript
/** @type {import('tailwindcss').Config} */
export default {
content: [
"./index.html",
"./src/**/*.{js,ts,jsx,tsx}",
],
theme: {
extend: {},
},
plugins: [],
}
```
`src\index.css`:
```css
@tailwind base;
@tailwind components;
@tailwind utilities;
```
### Tanstack Router Setup
The development environment for our project is ready. In this section, we will install and configure TanStack Router, which is the main focus of this project. Let's start by installing the TanStack Router library.
Enter the following commands:
```bash
npm install @tanstack/react-router
npm install --save-dev @tanstack/react-router-vite-plugin
```
The `@tanstack/react-router-vite-plugin` will regenerate the routes whenever our application compiles.
Next, we set up Vite to use the plugin we just installed.
Enter the following code in `vite.config.ts`:
```typescript
// vite.config.ts
import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import { TanStackRouterVite } from "@tanstack/router-vite-plugin";
// https://vitejs.dev/config/
export default defineConfig({
plugins: [react(), TanStackRouterVite()],
});
```
### The Routes Directory
All route implementations for our application are carried out in the' routes' directory.
In the source[`src`] directory, create a new subdirectory called `routes`. This directory will contain all the routes of our application. Tanstack Router will infer routes based on its folder structure via filenames.
Next, inside the `routes` directory create the files `__root.tsx` and `index.tsx` respectively.
```
📦 movie-app
┣ 📂 src
┃ ┣ 📂 routes
┃ ┣ 📄 __root.tsx
┃ ┣ 📄 index.tsx
```
Next, run the following command:
```bash
npm run dev
```
The preceding command will generate a *[routeTree](https://tanstack.com/router/latest/docs/framework/react/guide/creating-a-router#route-tree)* for our application located in `routeTree.gen.ts` inside the `src` directory.
```typescript
// src\routeTree.gen.ts
import { Route as rootRoute } from "./routes/__root";
import { Route as IndexImport } from "./routes/index";
// Create/Update Routes
const IndexRoute = IndexImport.update({
path: "/",
getParentRoute: () => rootRoute,
} as any);
// Populate the FileRoutesByPath interface
declare module "@tanstack/react-router" {
interface FileRoutesByPath {
"/": {
preLoaderRoute: typeof IndexImport;
parentRoute: typeof rootRoute;
};
}
}
// Create and export the route tree
export const routeTree = rootRoute.addChildren([IndexRoute]);
```
### Router Instance
The router instance is the mechanism that connects TanStack Router to our React application—just like `<BrowserRouter>` [from React Router](https://reactrouter.com/en/main/router-components/browser-router).
Enter the following code in `App.tsx`:
```typescript
// src\App.tsx
import { RouterProvider, createRouter } from "@tanstack/react-router";
import { routeTree } from "./routeTree.gen";
const router = createRouter({ routeTree });
declare module "@tanstack/react-router" {
interface Register {
router: typeof router;
}
}
function App() {
return <RouterProvider router={router} />;
}
export default App;
```
The preceding code creates a router instance via the `createRouter` function from TanStack Router, which ensures all declared routes are *100% type-safe*.
### Layout Route
The layout route is the parent container of all routes in our application.
Enter the following code in `__root.tsx`:
```typescript
// src\routes\__root.tsx
import { createRootRoute, Outlet, Link } from '@tanstack/react-router';
export const Route = createRootRoute({
component: LayoutComponent,
});
function LayoutComponent() {
return (
<html lang='en'>
<head>
<meta charSet='UTF-8' />
<meta name='viewport' content='width=device-width, initial-scale=1.0' />
<title>Movie-App</title>
</head>
<body className='bg-black max-w-4xl mx-auto text-white px-5 md:px-0'>
<header className='flex justify-between items-center p-4 bg-[#780909] text-white rounded-b-2xl shadow-xl shadow-[#df0707] mb-6'>
<h1 className='text-2xl flex'>
<Link
to='/'
search={{ page: 1 }}
activeProps={{
className: 'font-bold hello',
}}
activeOptions={{
includeSearch: false,
}}
>
Movies🍿
</Link>
<div className='mx-5'>|</div>
<Link
to='/search'
search={{ q: '' }}
activeProps={{
className: 'font-bold',
}}
>
Search
</Link>
</h1>
<div id='favorites-count'>{/* <FavoritesCount /> */}</div>
</header>
<Outlet /> {/* Start rendering router matches */}
</body>
</html>
);
}
```
The preceding code does the following:
- Creates a root route component(via `createRootRoute`) that will be displayed on every application page.
- Implements basic navigation for our application via the `Link` component for TanStack Router.
- Renders other paths that the router will match via the `<Outlet/>` component from TanStack Router.
- Finally, applies styles in markup via tailwind classes.
Next, if the `npm run dev` command is still running, you should get the following output in your browser.
Browser Output:
### Building the Movies Index-Page
In this section, we will build the index page of our app, where all the movies retrieved from an API will be displayed in a paginated view.
*N/B: We'll use the [TMDb REST API](https://developer.themoviedb.org/docs/getting-started), which provides information about various popular TV shows and movies. Get an API key.*
When you ran the `npm run dev` command after setting up TanStack Router, along with the *routeTree* being generated, placeholder code was also generated for each file in the `routes` directory. So, your `index.tsx` page should look like this:
```typescript
// src\routes\index.tsx
import { createFileRoute } from '@tanstack/react-router';
export const Route = createFileRoute('/')({
component: () => <div>Hello/!</div>,
});
```
In the preceding code, we have a basic route implementation with TanStack Router. Unlike other file-based routers where components are exported, we export the *file route* instead. We create the file route via *[createFileRoute function](https://tanstack.com/router/latest/docs/framework/react/api/router/createFileRouteFunction#createfileroute-function)*, which accepts a single argument of type `string` that represents the *path* of the file that the route will be inferred from. Finally, we pass in a `component` that will be rendered when we hit the route path.
### Pagination
Let's implement the pagination feature to allow us to view data retrieved from the API in paginated segments.
First, we will create the pagination component.
In the `src` directory create a subdirectory called `components` and then create a `paging.tsx` file.
Enter the following code in `paging.tsx`
```typescript
import React from 'react';
import { Link } from '@tanstack/react-router';
export default function Paging({
pages,
Route,
page,
}: {
pages: number;
Route: any;
page: number;
}) {
return (
<div className='flex gap-1 text-xl font-bold justify-end'>
{new Array(pages).fill(0).map((_, i) =>
page === i + 1 ? (
<div className='px-4 py-2 border border-red-300 rounded bg-[#0b0000] text-white'>
{i + 1}
</div>
) : (
<Link
key={i}
from={Route.id}
search={{
page: i + 1,
}}
className='px-4 py-2 border border-red-300 rounded hover:bg-[#a33d3da1]'
>
{i + 1}
</Link>
)
)}
</div>
);
}
```
In the preceding code, we have a basic react presentational component. The pagination logic and conditional rendering based on the logic are in the' return' block of the component.
The pagination logic is basically:
- A new array is created with its length set to the number of pages that will be paginated via the `pages` prop.
- Each index in the array is *filled* with`0`— `array.fill(0)`
- The looped through via the `map()` function, where we check if the current page we have in our search param(via `page` prop) equals the index of the current array item.
- Next, a presentational component is shown depending on the result of the preceding condition.
- The *[Link](https://tanstack.com/router/latest/docs/framework/react/api/router/linkComponent#link-props)* component is used to navigate to a new page if the conditional is `true`—i.e, the search param(`page`) equals the current index(`i`). Check the docs for prop options([from](https://tanstack.com/router/latest/docs/framework/react/api/router/PathParamOptionsType), [search](https://tanstack.com/router/latest/docs/framework/react/api/router/SearchParamOptionsType)) used in the Link component.
- Finally, markup is styled with tailwind.
Next, we will build the index route, where movies will be retrieved from the API and paginated.
Enter the following code in `index.tsx`:
```typescript
// src\routes\index.tsx
import { createFileRoute, Link } from "@tanstack/react-router";
import { z } from "zod";
import Paging from "../components/Paging";
export const Route = createFileRoute("/")({
component: IndexComponent,
validateSearch: z.object({
page: z.number().catch(1),
}),
});
function IndexComponent() {
const pages = 4;
const { page } = Route.useSearch();
return (
<div>
<div className="flex justify-end pr-5 py-5">
<Paging page={page} pages={pages} Route={Route} />
</div>
</div>
);
}
```
The preceding code does the following:
- The *zod* library is used to manage and type our search parameters.
- The `validateSearch` option in `createFileRoute`is used to validate our search parameters from the URL via the zod library. In this case `page` must be `number` with a default value of `1`.
- The `IndexComponent` is a component that will be rendered when the route path is matched.
- In `IndexComponent`, *[useSearch hook](https://tanstack.com/router/latest/docs/framework/react/api/router/useSearchHook)* is used to access the current value of the `page` search parameter.
- The `pages` variable represents the number of pages for pagination.
- Required props are passed to the `Paging` component.
**Browser output:**
### Retrieving Data
We will be retrieving the data for our application from the [TMDb API](https://developer.themoviedb.org/reference/intro/getting-started) which will require an API key, get it [here](https://www.themoviedb.org/settings/api).
Next, create an `api.ts` file in the `src` directory and enter the following code:
```typescript
// get all Movies
export async function getMovies(page: number = 1) {
const response = await fetch(
`https://api.themoviedb.org/3/movie/popular?include_adult=false&language=en-US&page=${encodeURIComponent(page)}&api_key=${API_KEY}`
)
.then((r) => r.json())
.then((r) => ({
pages: 4,
movies: r.results,
}));
return response;
}
```
In the preceding code, the exported `getMovies()` function is used to fetch data from the API. It accepts a `page` parameter from the URL search parameters. Finally, it returns an object, where the `pages` property represents the number of pages, and `movies` is the data gotten from the API to be displayed on the UI.
Now, in `index.tsx`, enter the following code:
```typescript
// src\routes\index.tsx
import { createFileRoute, Link } from "@tanstack/react-router";
import Paging from "../components/Paging";
import { getMovies } from "../api";
import { z } from "zod";
export const Route = createFileRoute("/")({
component: IndexComponent,
validateSearch: z.object({
page: z.number().catch(1),
}),
loaderDeps: ({ search: { page } }) => ({ page }),
loader: ({ deps: { page } }) => getMovies(page),
});
function IndexComponent() {
const { page } = Route.useSearch();
const { movies, pages } = Route.useLoaderData();
return (
<div>
<div className="flex justify-end pr-5 py-5">
<Paging page={page} pages={pages} Route={Route} />
</div>
<div>{JSON.stringify(movies, null, 2)}</div>
</div>
);
}
```
In the preceding code, note the following:
- The `getMovies()` is imported and used. It gives us access to data from the API.
- The `/` route support pagination via the search param `page`. For this data to be stored in a cache, it has to be accessed via the `loaderDeps` function.
- The `loader` gets the `page` search param stored in cache and uses it to get data from the API via the `getMovies()` function.
- `Route.useLoaderData()` gives us access to the data loaded in the [loader](https://tanstack.com/router/latest/docs/framework/react/guide/data-loading#route-loaders).
- Finally, `JSON.stringify()` is used to show the data on the UI.
Browser Output:
Now, let's create a presentational component to make our UI more presentable:
In the `components` directory create `MovieCards.tsx` file, and add the following code:
```typescript
import { Link } from '@tanstack/react-router';
export default function IndexComponent({ movies }: { movies: any[] }) {
return (
<div className='grid grid-cols-1 md:grid-cols-2'>
{movies.map((m, i) => (
<Link
to='/movies/$movieId'
params={{
movieId: m.id,
}}
className='flex m-2'
key={m.id || i}
>
<img
src={`https://image.tmdb.org/t/p/w500${m.poster_path}`}
className='rounded-tl-lg rounded-bl-lg aspect-w-5 aspect-h-7 w-1/4'
/>
<div className='w-3/4 flex flex-col'>
<div className='font-bold text-xl px-4 bg-[#ba0c0c] text-white py-2 rounded-tr-md'>
{m.original_title}
</div>
<div className='border-red-900 border-b-2 border-r-2 rounded-br-lg flex-grow pt-3'>
<div className='italic line-clamp-2 px-4'>{m.overview}</div>
<div className='flex justify-between px-4 pt-3 items-center'>
{/* <FavoriteButton movieId={m.id} /> */}
<div>{m.vote_average.toFixed(1)} out of 10</div>
</div>
</div>
</div>
</Link>
))}
</div>
);
}
```
>N/B: The path `/movies/$movieId` in the `to` property in `Link` is not yet defined, so you will see an error. We will fix it in the next section.
Next, we will import this component into `index.tsx`, where it will replace `JSON.stringify()`, which is currently being used.
```typescript
.....
import MovieCards from "../components/MovieCards";
....
function IndexComponent() {
const { page } = Route.useSearch();
const { movies, pages } = Route.useLoaderData();
return (
<div>
<div className="flex justify-end pr-5 py-5">
<Paging page={page} pages={pages} Route={Route} />
</div>
<MovieCards movies={movies} />
</div>
);
}
```
Browser Output:
Our app's UI looks better now.
### Building The Movie Detail Page
The movie detail page displays the details of a single movie when it is clicked on.
### Using Path Parameters
*According to the [Tanstack Official Docs](https://tanstack.com/router/latest/docs/framework/react/guide/path-params#path-params):*
> *Path params are used to match a single segment (the text until the next `/`) and provide its value back to you as a named variable. They are defined by using the `$` character prefix in the path, followed by the key variable to assign it to.*
To implement the movie details functionality, we will use *[path parameters](https://tanstack.com/router/latest/docs/framework/react/guide/path-params#path-params)*, this will allow us to define dynamic routes via each movie `id`.
In the `routes` directory, create a new `movies` subdirectory, in the `movies` directory create a `$movieId.tsx`. This file will contain the logic for fetching an individual movie from TMDb API.
Enter the following code in `$movieId.tsx`:
```typescript
import { createFileRoute } from "@tanstack/react-router";
export const Route = createFileRoute("/movies/$movieId")({
component: MovieDetail,
});
function MovieDetail() {
return <h1>Movie!!!</h1>;
}
```
The preceding code is a basic implementation of the movie detail functionality without data from an API. The `MovieDetail` component is rendered when the path matches `/movies/$movieId`, where `$movieId` stands for the `id` of the movie that is clicked on the index page.
Browser Output:
Now, let's create a component for the movie details.
In the `component` directory, create a `Movie.tsx` file, and add the following code:
```typescript
import type { Movie } from '../types';
export default function Movie({ movie }: { movie: Movie }) {
return (

.join(', ')}
</div>
</div>
</div>
</div>
</div>
);
}
```
Now, let's get the movie details from the API.
Enter the following code in the `api.ts` file.
```typescript
....
// get Movie by Id
export async function getMovie(id: string) {
const response = await fetch(
`https://api.themoviedb.org/3/movie/${id}?language=en-US&api_key=${API_KEY}`
).then((r) => r.json());
return response;
}
```
The preceding code is a fetch request that retrieves details for individual movies based on their `id`.
Now, enter the following code in `$movieId.tsx`:
```typescript
import { createFileRoute } from "@tanstack/react-router";
import { getMovie } from "../../api";
import Movie from "../../components/Movie";
export const Route = createFileRoute("/movies/$movieId")({
component: MovieDetail,
loader: ({ params: { movieId } }) => getMovie(movieId),
});
function MovieDetail() {
const movie = Route.useLoaderData();
return <Movie movie={movie} />;
}
```
The above code does the following:
- The `getMovie()` function is imported from `api.tsx`.
- No need for `loaderDeps`, because we are working with path params. We simply pass the parameter into `loader`.
- `useLoaderData()` is used to access data from the `loader`.
- The `<Movie/>` component is used to display the movie detail on the UI.
Browser Output:
### Building Movie Search
The search feature will enable us to search for specific movies in our app. So, we will build a *search route* to implement this feature.
### Search Params for State Management
We will be storing our search query in the URL via search params, the code below shows how this is done with Tanstack Router.
In the `routes` directory, create a `search.tsx` file. Add the following code:
```typescript
import { createFileRoute, useNavigate} from "@tanstack/react-router";
import { useState } from "react";
interface SearchParams {
query: string;
}
export const Route = createFileRoute("/search")({
component: SearchRoute,
validateSearch: (search: { query: string }): SearchParams => {
return {
query: (search.query as string) || "",
};
},
});
function SearchRoute() {
const { query } = Route.useSearch();
const navigate = useNavigate({ from: Route.id });
const [newQuery, setNewQuery] = useState(query);
return (
<div className="p-2">
<div className="flex gap-2">
<input
value={newQuery}
onChange={(e) => {
setNewQuery(e.target.value);
}}
onKeyUp={(e) => {
if (e.key === "Enter") {
navigate({
search: (old: { query: string }) => ({
...old,
query: newQuery,
}),
});
}
}}
className="border-2 border-gray-300 rounded-md p-1 text-black w-full"
/>
<button
onClick={() => {
navigate({
search: (old: { query: string }) => ({
...old,
q: newQuery,
}),
});
}}
>
Search
</button>
</div>
// Results
</div>
);
}
```
The preceding code does the following:
- We define the `/search` route with the `createFileRoute()` function from TanStack Router.
- The [`validateSearch`](https://tanstack.com/router/latest/docs/framework/react/guide/search-params#validating-search-params) option is used to validate the search params of the `/search` route, it also returns a typed `SearchParams` object with a query property set to `string`.
- The `SearchRoute` component accesses the search param via `Route.useSearch()`.
- We use the `useNavigate` function from [TanStack Router](https://tanstack.com/router/latest/docs/framework/react/guide/navigation#usenavigate) to programmatically navigate from the `/search` route —`useNavigate({ from: Route.id })`.[]
- The `useState` hook for React is used to update the state of the `SearchRoute` component based on the search param `query`.
- In the `return` block, we update the search param based on the `input` `value` typed in by the user as a search query. Also, the `useNavigate` function is used to update *search* string(`query`) to what is currently being typed by the user via the [SearchParamOptions type](https://tanstack.com/router/latest/docs/framework/react/api/router/SearchParamOptionsType)
Browser Output:
In the above demo, you will notice that the search param in the URL got updated to the query that was entered in the search box.
### Showing Search Results
With the search functionality in place, the next step is to display the search result(s). For this, we will create a *nested route* inside the search route, which will also serve as an *[index route](https://tanstack.com/router/latest/docs/framework/react/guide/routing-concepts#index-routes)* of the search route.
### Nested Routing
The *[Outlet Componet](https://tanstack.com/router/latest/docs/framework/react/api/router/outletComponent#outlet-component)* is used to create nested routes in TanStack Router. Since the search route will be the parent route of the nested route, the outlet component is used here:
```typescript
// src\routes\search.tsx
import { createFileRoute, useNavigate, Outlet } from "@tanstack/react-router";
....
function SearchRoute() {
....
return (
<div className="p-2">
<div className="flex gap-2">
.....
</div>
<Outlet />
</div>
);
}
```
In the preceding code, the `<Outlet/>` component was added to the `SearchRoute` component in `search.tsx`. This is where the result(s) for our search query will be displayed.
First, let's retrieve the search results data from the API. Add the following code in `api.ts`
```typescript
......
// Search Movie
export async function searchMovie(query: string = "") {
const response = await fetch(
`https://api.themoviedb.org/3/search/movie?query=${encodeURIComponent(
query
)}&include_adult=false&language=en-US&page=1&api_key=${API_KEY}`
)
.then((r) => r.json())
.then((r) => r.results);
return response;
}
```
In the preceding code is the logic for retrieving search results from the TMDb API.
Next, in the `routes` directory, create the `search.index.tsx` file, and add the following code:
```typescript
import { createFileRoute } from "@tanstack/react-router";
import MovieCards from "../components/MovieCards";
import { searchMovie } from "../api";
interface SearchParams {
query: string;
}
export const Route = createFileRoute("/search/")({
component: SearchRoute,
loaderDeps: ({ search: { query } }) => ({ query }),
loader: async ({ deps: { query } }) => {
const searched_movies = await searchMovie(query);
return {
searched_movies,
};
},
validateSearch: (search: { query: string }): SearchParams => {
return {
query: (search.query as string) || "",
};
},
});
function SearchRoute() {
const { searched_movies } = Route.useLoaderData();
return (
<>
<MovieCards movies={searched_movies || []} />
</>
);
}
```
In the preceding code:
- We defined the `/search/` file route, which is the index route of the search route `/search`
- `validateSearch` is used to get the query, which will enable the interior index(`/search/`) to be routed into the `<Outlet/>` of the parent route(`/search`).
- The `searchMovie()` function retrieves movie results from the API via the `query` parameter.
- `loaderDeps` caches the search query, which is then used by the `loader` to fetch the search results.
- Finally, `useLoaderData` allows the search results to be accessed by the `SearchRoute` component. `SearchRoute` renders the results on the UI via the `<MovieCards/>` component.
Browser Output:
### Streaming Search Results
In this section, we are going to add some lazy-loading and code-splitting to our application.
We will display details for the first movie returned from the search results at the top of the page, the [*defer function*](https://tanstack.com/router/latest/docs/framework/react/api/router/deferFunction#:~:text=The%20defer%20function%20wraps%20a,promise%20is%20resolved%20or%20rejected.) and *[Await component](https://tanstack.com/router/latest/docs/framework/react/api/router/awaitComponent#await-component)* from TanStack Router will be used to enable other search results to be displayed sooner, without waiting for the details of the first movie to be rendered.
Sample UI:
### Fallbacks with React Suspense
Enter the following code in `search.index.tsx`:
```typescript
import { createFileRoute, defer, Await } from "@tanstack/react-router";
import { Suspense } from "react";
import MovieCards from "../components/MovieCards";
import Movie from "../components/Movie";
import { searchMovie, getMovie } from "../api";
interface SearchParams {
query: string;
}
export const Route = createFileRoute("/search/")({
component: SearchRoute,
loaderDeps: ({ search: { query } }) => ({ query }),
loader: async ({ deps: { query } }) => {
const searched_movies = await searchMovie(query);
return {
searched_movies,
firstMovie: searched_movies?.[0]?.id
? defer(getMovie(searched_movies[0].id))
: null,
};
},
validateSearch: (search: { query: string }): SearchParams => {
return {
query: (search.query as string) || "",
};
},
});
function SearchRoute() {
const { searched_movies, firstMovie } = Route.useLoaderData();
// fallbacks with React Suspense
return (
<>
{firstMovie && (
<div className="my-5">
<Suspense fallback={<div>Loading...</div>}>
<Await promise={firstMovie}>
{(movie) => {
return <Movie movie={movie} />;
}}
</Await>
</Suspense>
</div>
)}
<MovieCards movies={searched_movies || []} />
</>
);
}
```
In the preceding code:
- `getMovie()` calls the same API endpoint as movie details page in `$movieId.tsx`
- In `loader`, the data(first movie details) from `getMovie()` is *deferred* if the data is available via the [*defer function*](https://tanstack.com/router/latest/docs/framework/react/api/router/deferFunction#:~:text=The%20defer%20function%20wraps%20a,promise%20is%20resolved%20or%20rejected.).
- `defer()` allows us to lazy-load the data(first movie details), in case the API endpoint for the movie details takes time, we can show other search results before the first movie details.
- In the `return` block of the `SearchRoute` component:
- `Suspense` is used to provide a *fallback* until the promise(first movie details) from the [`Await`](https://tanstack.com/router/latest/docs/framework/react/api/router/awaitComponent#await-component) component is resolved.
- The *first movie details* is rendered via `<Movie/>` component to the UI.
Browser Output:
## Summary

1,893,155 | OKX futures contract hedging strategy by using C++ | Speaking of hedging strategies, there are various types, diverse combinations, and diverse ideas in... | 0 | 2024-06-19T05:25:43 | https://dev.to/fmzquant/okx-futures-contract-hedging-strategy-by-using-c-2hbf | strategy, okx, contract, hedging | Speaking of hedging strategies, there are various types, diverse combinations, and diverse ideas in various markets. We explore the design ideas and concepts of the hedging strategy from the most classic intertemporal hedging. Today, the crypto currency market is much more active than at the beginning, and there are also many futures contract exchanges that offer plenty of opportunities for arbitrage hedging. Spot cross-market arbitrage, cash hedge arbitrage, futures intertemporal arbitrage, futures cross-market arbitrage, etc., crypto quantitative trading strategies emerge one after another. Let's take a look at a "hardcore" intertemporal hedging strategy written in C++ and trading on the OKEX exchange. The strategy is based on the FMZ Quant quantitative trading platform.
## Principle of strategy
Why is the strategy somewhat hardcore because the strategy is written in C++ and the strategy reading is slightly more difficult. But it does not prevent readers from learning the essence of this strategy design and ideas. The strategy logic is relatively simple, the code length is moderate, only 500 lines. In terms of market data acquisition, unlike the other strategies that use the "rest" interface. This strategy uses the "websocket" interface to accept exchange market quotes.
In terms of design, the strategy structure is reasonable, the code coupling degree is very low, and it is convenient to expand or optimize. The logic is clear, and such a design is not only easy to understand. As a teaching material, learning this strategy's design is also a good example. The principle of this strategy is relatively simple, that is, does the spread of forward contract and recent contract are positive or negative? the basic principle is consistent with the intertemporal hedging of commodity futures.
**- Spread Positive, selling short forward contracts, buying long recent contracts.**
**- Spread negative, buying long forward contracts, selling short recent contracts.**
After understand the basic principles, the rest is how the strategy triggers the opening position of the hedge, how to close the position, how to add positions, total position control method and other strategy details processing.
The hedging strategy is mainly concerned with the fluctuation of the subject price difference (The Spread) and the regression of it. However, the difference is likely to fluctuate slightly, or to oscillate sharply, or in one direction.
This brings uncertainty about hedging profits and losses, but the risk is still much smaller than the unilateral trend. For the various optimizations of the intertemporal strategy, we can choose to start from the position controlling level and the opening and closing trigger condition. For example, we can use the classic "Bollinger band Indicator" to determine the price fluctuation. Due to the reasonable design and low coupling degree, this strategy can be easily modified into the "Bollinger index intertemporal hedging strategy"
## Analysis of strategy code
Looking at the code throughout, you can conclude that the code is roughly divided into four parts.
1. Enumerate value definitions, define some state values, and use to mark states. Some functional functions that are not related to the strategy, such as url encoding functions, time conversion functions, etc., have no relationship with the strategy logic, just for the data processing.
2. K-line data generator class: The strategy is driven by the K-line data generated by the generator class object.
3. Hedging class: Objects of this class can perform specific trading logic, hedging operations, and processing details of the strategy.
4. The main function of the strategy, which is the "main" function. The main function is the entry function of the strategy. The main loop is executed inside this function. In addition, this function also performs an important operation, that is, accessing the websocket interface of the exchange, and obtaining the pushed raw tick market data as the K-line data generator.
**Through the overall understanding of the strategy code, we can gradually learn the various aspects of the strategy, and then study the design, ideas and skills of the strategy.**
- Enumeration value definition, other function functions
1. enumerated type State statement
```
enum State { // Enum type defines some states
STATE_NA, // Abnormal state
STATE_IDLE, // idle
STATE_HOLD_LONG, // holding long positions
STATE_HOLD_SHORT, // holding short positions
};
```
Because some functions in the code return a state, these states are defined in the enumeration type State.
Seeing that STATE_NA appears in the code is abnormal, and STATE_IDLE is idle, that is, the state of the operation can be hedged. STATE_HOLD_LONG is the state in which the positive hedge position is held. STATE_HOLD_SHORT is the state in which the negative hedge position is held.
2. String substitution, not called in this strategy, is an alternate utility function, mainly dealing with strings.
```
string replace(string s, const string from, const string& to)
```
3. A Function for converting to hexadecimal characters toHex
```
inline unsigned char toHex(unsigned char x)
```
4. Handling url encoded functions
```
std::string urlencode(const std::string& str)
```
5. A time conversion function that converts the time in string format to a timestamp.
```
uint64_t _Time(string &s)
```
- K line data generator class
```
Class BarFeeder { // K line data generator class
Public:
BarFeeder(int period) : _period(period) { // constructor with argument "period" period, initialized in initialization list
_rs.Valid = true; // Initialize the "Valid" property of the K-line data in the constructor body.
}
Void feed(double price, Chart *c=nullptr, int chartIdx=0) { // input data, "nullptr" null pointer type, "chartIdx" index default parameter is 0
Uint64_t epoch = uint64_t(Unix() / _period) * _period * 1000; // The second-level timestamp removes the incomplete time period (incomplete _period seconds) and is converted to a millisecond timestamp.
Bool newBar = false; // mark the tag variable of the new K line Bar
If (_rs.size() == 0 || _rs[_rs.size()-1].Time < epoch) { // If the K line data is 0 in length. Or the last bar's timestamp is less than epoch (the last bar of the K line is more than the current most recent cycle timestamp)
Record r; // declare a K line bar structure
r.Time = epoch; // Construct the K line bar of the current cycle
r.Open = r.High = r.Low = r.Close = price; // Initialize the property
_rs.push_back(r); // K line bar is pressed into the K line data structure
If (_rs.size() > 2000) { // If the K-line data structure length exceeds 2000, the oldest data is removed.
_rs.erase(_rs.begin());
}
newBar = true; // tag
} else { // In other cases, it is not the case of a new bar.
Record &r = _rs[_rs.size() - 1]; // Reference the data of the last bar in the data.
r.High = max(r.High, price); // The highest price update operation for the referenced data.
r.Low = min(r.Low, price); // The lowest price update operation for the referenced data.
r.Close = price; // Update the closing price of the referenced data.

```
This class is mainly responsible for processing the acquired tick data into a difference K line for driving the strategy hedging logic.
Some readers may have questions, why use tick data? Why construct a K-line data generator like this? Is it not good to use K-line data directly? This kind of question has been issued in three bursts. When I wrote some hedging strategies, I also made a fuss. I found the answer when I wrote the "Bollinger hedge strategy". Since the K-line data for a single contract is the price change statistics for this contract over a certain period of time.
The K-line data of the difference between the two contracts is the difference price change statistics in a certain period. Therefore, it is not possible to simply take the K-line data of each of the two contracts for subtraction and calculate the difference of each data on each K-line Bar. The most obvious mistake is, for example, the highest price and the lowest price of two contracts, not necessarily at the same time. So the subtracted value doesn't make much sense.
Therefore, we need to use real-time tick data to calculate the difference in real time and calculate the price change in a certain period in real time (that is, the highest, lowest, open and close price on the K-line column). So we need a K-line data generator, as a class, a good separation of processing logic.
- Hedging class
```
Class Hedge { // Hedging class, the main logic of the strategy.
Public:
Hedge() { // constructor
...
};
State getState(string &symbolA, Depth &depthA, string &symbolB, Depth &depthB) { // Get state, parameters: contract A name, contract A depth data, contract B name, contract B depth data
...
}
Bool Loop(string &symbolA, Depth &depthA, string &symbolB, Depth &depthB, string extra="") { // Opening and closing position main logic
...
}
Private:
Vector<double> _addArr; // Hedging adding position list
String _state_desc[4] = {"NA", "IDLE", "LONG", "SHORT"}; // Status value Description
Int _countOpen = 0; // number of opening positions
Int _countCover = 0; // number of closing positions
Int _lastCache = 0; //
Int _hedgeCount = 0; // number of hedging
Int _loopCount = 0; // loop count (cycle count)
Double _holdPrice = 0; // holding position price
BarFeeder _feederA = BarFeeder(DPeriod); // A contract Quote K line generator
BarFeeder _feederB = BarFeeder(DPeriod); // B contract Quote K line generator
State _st = STATE_NA; // Hedging type Object Hedging position status
String _cfgStr; // chart configuration string
Double _holdAmount = 0; // holding position amount
Bool _isCover = false; // the tag of whether to close the position
Bool _needCheckOrder = true; // Set whether to check the order
Chart _c = Chart(""); // chart object and initialize
};
```
Because the code is relatively long, some parts are omitted, this is mainly showing the structure of this hedge class, the constructor Hedge function is omitted, mainly for the purpose the object initialization. Next, we introduce the two main "function" functions.
**getState**
This function mainly deals with order inspection, order cancellation, position detection, position balancing and so on. Because in the process of hedging transactions, it is impossible to avoid a single leg (that is, a contract is executed, another one is not), if the examination is performed in the placing order logic, and then the processing of the re-send order operation or closing position operation, the strategy logic will be chaotic.
So when designing this part, I took another idea. If the hedging operation is triggered, as long as the order is placed once, regardless of whether there is a single-leg hedging, the default is that the hedging is successful, and then the position balance is detected in the getState function, and the logic for processing the balance will be deal with independently.
**Loop**
The trading logic of the strategy is encapsulated in this function, in which getState is called, and the K-line data generator object is used to generate the K-line data of the difference(the spread), and the judgment of opening, closing, and adding position logic is performed. There are also some data update operations for the chart.
- Strategy main function
```
Void main() {
...
String realSymbolA = exchange.SetContractType(symbolA)["instrument"]; // Get the A contract (this_week / next_week / quarter ), the real contract ID corresponding to the week, next week, and quarter of the OKEX futures contract.
String realSymbolB = exchange.SetContractType(symbolB)["instrument"]; // ...
String qs = urlencode(json({{"op", "subscribe"}, {"args", {"futures/depth5:" + realSymbolA, "futures/depth5:" + realSymbolB}}}).dump()) ; // JSON encoding, url encoding for the parameters to be passed on the ws interface
Log("try connect to websocket"); // Print the information of the connection WS interface.
Auto ws = Dial("wss://real.okex.com:10442/ws/v3|compress=gzip_raw&mode=recv&reconnect=true&payload="+qs); // Call the FMZ API "Dial" function to access the WS interface of OKEX Futures
Log("connect to websocket success");
Depth depthA, depthB; // Declare two variables of the depth data structure to store the depth data of the A contract and the B contract
Auto fillDepth = [](json &data, Depth &d) { // Construct the code for the Depth data with the json data returned by the interface.
d.Valid = true;
d.Asks.clear();
d.Asks.push_back({atof(string(data["asks"][0][0]).c_str()), atof(string(data["asks"][0][1]).c_str( ))});
d.Bids.clear();
d.Bids.push_back({atof(string(data["bids"][0][0]).c_str()), atof(string(data["bids"][0][1]).c_str( ))});
};
String timeA; // time string A
String timeB; // time string B
While (true) {
Auto buf = ws.read(); // Read the data pushed by the WS interface
...
}
```
After the strategy is started, it is executed from the main function. In the initialization of the main function, the strategy subscribes to the tick market of the websocket interface. The main job of the main function is to construct a main loop that continuously receives the tick quotes pushed by the exchange's websocket interface, and then calls the member function of the hedge class object: Loop function. The trading logic in the Loop function is driven by the market data.
One point to note is that the tick market mentioned above is actually the subscription order thin depth data interface, which is the order book data for each file. However, the strategy only uses the first file of data, in fact, it is almost the same as the tick market data. The strategy does not use the data of other files, nor does it use the order value of the first file.
Take a closer look at how the strategy subscribes to the data of the websocket interface and how it is set up.
```
string qs = urlencode(json({{"op", "subscribe"}, {"args", {"futures/depth5:" + realSymbolA, "futures/depth5:" + realSymbolB}}}).dump());
Log("try connect to websocket");
auto ws = Dial("wss://real.okex.com:10442/ws/v3|compress=gzip_raw&mode=recv&reconnect=true&payload="+qs);
Log("connect to websocket success");
```
First, the url encoding of the subscription message json parameter passed by the subscribed interface, that is, the value of the payload parameter. Then an important step is to call the FMZ Quant platform's API interface function Dial function. The Dial function can be used to access the exchange's websocket interface. Here we make some settings, let the websocket connection control object ws to be created have automatic reconnection of disconnection (the subscription message still uses the value qs string of the payload parameter), to achieve this function, you need to add configuration in the parameter string of the Dial function.
The beginning of the Dial function parameter is as follows:
```
wss://real.okex.com:10442/ws/v3
```
This is the address of the websocket interface that needs to be accessed, and is separated by "|".
Compress=gzip_raw&mode=recv&reconnect=true&payload="+qs are all
configuration parameters.
After this setting, even if the websocket connection is disconnected, FMZ Quant trading platform's underlying system of the docker system will automatically reconnect and get the latest market data in time.
Grab every price fluctuation and quickly capture the right hedge.
- Position control
Position control is controlled using a ratio of hedge positions similar to the “Bofinacci” series.
```
For (int i = 0; i < AddMax + 1; i++) { // Construct a data structure that controls the number of scalping, similar to the ratio of the Bofinac sequence to the number of hedges.
If (_addArr.size() < 2) { // The first two added positions are changed as: Double the number of hedges
_addArr.push_back((i+1)*OpenAmount);
}
_addArr.push_back(_addArr[_addArr.size()-1] + _addArr[_addArr.size()-2]); // The last two adding positions are added together, and the current position quantity is calculated and stored in the "_addArr" data structure.
}
```
It can be seen that the number of additional positions added each time is the sum of the last two positions.
Such position control can realize the larger the difference, the relative increase of the arbitrage hedge, and the dispersion of the position, so as to grasp the small position of the small price fluctuation, and the large price fluctuation position is appropriately increased.
- Closing position: stop loss and take profit
Fixed stop loss spread and take profit spread.
When the position difference reaches the take profit position and the stop loss position, the take profit and stop loss are carried out.
- The designing of entering the market and leaving the market
The period of the parameter NPeriod control provides some dynamic control over the opening and closing position of the strategy.
- Strategy chart
The strategy automatically generates a spread K-line chart to mark relevant transaction information.
C++ strategy custom chart drawing operation is also very simple. You can see that in the constructor of the hedge class, we use the written chart configuration string _cfgStr to configure the chart object _c, _c is the private component of the hedge class. When the private member is initialized, the chart object constructed by the FMZ Quant platform custom chart API interface function is called.
```
_cfgStr = R"EOF(
[{
"extension": { "layout": "single", "col": 6, "height": "500px"},
"rangeSelector": {"enabled": false},
"tooltip": {"xDateFormat": "%Y-%m-%d %H:%M:%S, %A"},
"plotOptions": {"candlestick": {"color": "#d75442", "upColor": "#6ba583"}},
"chart":{"type":"line"},
"title":{"text":"Spread Long"},
"xAxis":{"title":{"text":"Date"}},
"series":[
{"type":"candlestick", "name":"Long Spread","data":[], "id":"dataseriesA"},
{"type":"flags","data":[], "onSeries": "dataseriesA"}
]
},
{
"extension": { "layout": "single", "col": 6, "height": "500px"},
"rangeSelector": {"enabled": false},
"tooltip": {"xDateFormat": "%Y-%m-%d %H:%M:%S, %A"},
"plotOptions": {"candlestick": {"color": "#d75442", "upColor": "#6ba583"}},
"chart":{"type":"line"},
"title":{"text":"Spread Short"},
"xAxis":{"title":{"text":"Date"}},
"series":[
{"type":"candlestick", "name":"Long Spread","data":[], "id":"dataseriesA"},
{"type":"flags","data":[], "onSeries": "dataseriesA"}
]
}
]
)EOF";
_c.update(_cfgStr); // Update chart objects with chart configuration
_c.reset(); // Reset chart data。
```
```
Call _c.update(_cfgStr); Use _cfgStr to configure to the chart object.
Call _c.reset(); to reset the chart data.
```
When the strategy code needs to insert data into the chart, it also calls the member function of the _c object directly, or passes the reference of _c as a parameter, and then calls the object member function (method) of _c to update the chart data and insert operation.
E.g:
```
_c.add(chartIdx, {{"x", UnixNano()/1000000}, {"title", action}, {"text", format("diff: %f", opPrice)}, {"color", color}});
```
After placing the order, mark the K line chart.
As follows, when drawing a K line, a reference to the chart object _c is passed as a parameter when calling the member function feed of the BarFeeder class.
```
void feed(double price, Chart *c=nullptr, int chartIdx=0)
```
That is, the formal parameter c of the feed function.
```
Json point = {bar.Time, bar.Open, bar.High, bar.Low, bar.Close}; // Construct a json type data
If (c != nullptr) { // The chart object pointer is not equal to the null pointer, do the following.
If (newBar) { // judge if the new Bar appears
C->add(chartIdx, point); // Call the chart object member function "add" to insert data into the chart object (new k line bar)
C->reset(1000); // only keep 1000 bar data
} else {
C->add(chartIdx, point, -1); // Otherwise update (not new bar), this point (update this bar).
}
}
```
Insert a new K-line Bar data into the chart by calling the add member function of the chart object _c.
```
c->add(chartIdx, point);
```

In OOP, objects are instances of classes, which define the structure and behavior of the object. This approach allows for the organization of code into modular and reusable components, enhancing code readability and maintainability.
Key principles of OOP include encapsulation, inheritance, and polymorphism. Encapsulation involves bundling data and methods within a class to restrict access and protect the integrity of the data. Inheritance allows one class to inherit properties and methods from another, promoting code reuse and establishing hierarchical relationships. Polymorphism enables objects to be treated as instances of their parent class, facilitating flexibility and extensibility in code design.
Proficiency in Java SE and Java EE
Java SE and Java EE are essential skills for developers working in the Java ecosystem. Java SE, also known as Standard Edition, provides the core Java programming language features and libraries that are fundamental for building applications. On the other hand, Java EE, which stands for Enterprise Edition, extends the capabilities of Java SE by offering additional APIs and tools for developing robust enterprise applications.
Proficiency in Java SE is crucial for mastering the basics of Java programming, such as syntax, data types, control structures, and object-oriented principles. Developers need to have a solid understanding of Java SE to write efficient and maintainable code. Java EE, on the other hand, equips developers with tools and technologies needed to build scalable and secure enterprise applications. It includes features like servlets, JavaServer Pages (JSP), Enterprise JavaBeans (EJB), and more, enabling developers to create complex, multi-tiered applications for businesses and organizations.
Experience with Spring Framework
Spring Framework is a powerful tool for Java developers, offering a comprehensive platform for building robust and scalable applications. With its extensive set of features, Spring simplifies the development process by providing solutions for various challenges faced during application development.[Hire dedicated java developer](https://www.appsierra.com/blog/hire-dedicated-java-developers) for better efficiency in software development.
Developers proficient in the Spring Framework can leverage its dependency injection and aspect-oriented programming capabilities to create modular and maintainable codebases. By utilizing Spring's features such as Spring MVC for web application development and Spring Security for implementing security measures, developers can streamline the development process and deliver high-quality software solutions.
Knowledge of Hibernate
Hibernate is a powerful and widely-used ORM (Object-Relational Mapping) framework in the Java ecosystem. It simplifies the task of persisting Java objects to a relational database by handling the mapping of Java classes to database tables and vice versa. With Hibernate, developers can focus more on their business logic rather than dealing with the complexities of SQL queries and database interactions.
One of the key benefits of using Hibernate is its automatic table generation feature, which eliminates the need for developers to manually create database tables. This feature not only saves time but also ensures consistency between the Java classes and the database schema. Additionally, Hibernate provides various querying options, including HQL (Hibernate Query Language) and Criteria API, making it easier to retrieve and manipulate data from the database.
Familiarity with RESTful web services
RESTful web services play a crucial role in modern software development, allowing applications to communicate over the web using standard protocols and conventions. By following the principles of REST, developers can design APIs that are easy to understand, flexible, and scalable. Understanding RESTful web services enables programmers to create interoperable systems that can be accessed by a wide range of clients, from web browsers to mobile devices.
Professionals familiar with RESTful web services are adept at designing APIs that adhere to REST principles, such as using standard HTTP methods like GET, POST, PUT, and DELETE. This familiarity empowers developers to create web services that are stateless, meaning each request contains all the information necessary for the server to fulfill it. Additionally, knowledge of RESTful web services allows programmers to incorporate best practices for security, caching, and versioning into their API designs, ensuring robust and efficient communication between clients and servers. | michaeljason_eb570f1a51d6 | |

Some people write code to master a programming language or framework. They want to be the best Java, C, or Python programmer, knowing all the ins and outs of the language. They write code because they love the process. While others meditate, read, or go for a walk, they open their computers and start typing.
I'm not that kind of programmer. I never was, and probably never will be. I don't care much about the programming language I use, as long as it's easy to read and write. I have never searched for a job because the company used a certain programming language I liked. Hell, I never even started at a new job already knowing the language the company used. I don't care about getting certifications to show off my expertise. While I sometimes enjoy the flow of coding, it's not my ultimate goal.
I write code for the results it brings. I love seeing [my most recently played song](https://yordi.me/show-your-recently-played-song-using-netlify-functions-and-lastfm/) every time I reload [my personal website](https://yordi.me/). I enjoy adding functionalities that aren't natively implemented, like [a search function on the Bear blogging platform](https://yordi.me/step-by-step-guide-implementing-search-in-bear-blog/). I find joy in teaching others how to code and seeing the spark in their eyes when a tough concept finally clicks.
Does this make me a non-typical programmer, someone who doesn't care much about the craft itself? Maybe. But in the long run, I don't mind. I code for my own reasons. And that's good enough. | yordiverkroost |

The capacity to access and retain financial data is becoming more prevalent as data breach concerns and redundancy increase. Having software that impedes your growth by failing to achieve this critical requirement might have a negative impact on your business.
That is why on-premise ERP software, such as Sage 100, is suitable for new enterprises that just need to meet basic needs. Now, [Sage Intacct](https://www.greytrix.com/sage-intacct/) enters the picture. It is a cloud-based ERP software that adapts and expands to meet changing business needs. Sage Intacct is the favored choice of modern enterprises because to its extensive capabilities in financial reporting, project management, accounting, and other areas.
Still unsure about the Sage 100 to Sage Intacct migration? Continue reading for a better understanding.
**Identify if you’ve outgrown Sage 100 to Sage Intacct:**
As businesses expand and adapt, so do their operational and financial management needs. That is why ERP software, such as [Sage 100 ERP](https://www.greytrix.com/sage-100/), must be capable of meeting complex and ever-changing corporate requirements. To maintain our business growth, we must transfer to a more well-vetted and agile cloud-based ERP system, such as Sage Intacct.
**Consider these reasons for [migrating from Sage 100 to Sage Intacct](https://www.greytrix.com/blogs/sageintacct/2024/06/14/migrating-from-sage-100-to-sage-intacct/):**

1,893,145 | Behind the Scenes with Redis: The Power of RESP Protocol | Ever wonder how Redis maintains its simplicity and efficiency over the network? Redis (Remote... | 0 | 2024-06-19T05:06:29 | https://dev.to/nayanraj-adhikary/behind-the-scenes-with-redis-the-power-of-resp-protocol-1g82 | webdev, redis, database, softwaredevelopment | Ever wonder how Redis maintains its simplicity and efficiency over the network?
Redis (Remote Dictionary Server) is a widely used in-memory data structure store that can be used as a database, cache, and message broker. One of the key aspects of Redis's efficiency and speed is its communication protocol, RESP (REdis Serialization Protocol).
This RESP helps the Redis client to communicate with the Redis server. This protocol was designed specifically for Redis, but you can use it in any client-server project.
RESP can serialize different data types including integers, strings, and arrays. It also features an error-specific type. A client sends a request to the Redis server as an array of strings.
## RESP versions
- As every protocol we have versions for RESP. Here are some of them.
1. Redis 2.0 supports RESP2 which become the standard
2. Redis 2 - Redis 7 supports RESP2 and RESP3
## RESP Magic
We have many data types that RESP supports. Let's look into some of them
Each of the data types has SET and GET commands for more inside you can look in the Redis Docs.
- Simple String: Simple strings are encoded with a `+` prefix followed by the string and terminated with `\r\n`.
```
+OK\r\n
```
- Errors: Errors are similar to simple strings but start with `-` prefix
```
-Error message\r\n
```
- Integers: Integers are encoded with a `:` prefix followed by the integer and terminated with `\r\n`.
```
:1000\r\n
```
- Arrays: Arrays are used to transmit multiple RESP types. They start with a `*` prefix followed by the number of elements in the array, a `\r\n`, and then the actual elements in RESP format.
```
*2\r\n$3\r\nfoo\r\n$3\r\nbar\r\n
```
If you notice each of the elements are separated by `\r\n`
## Communication Process
When a client sends a command to the Redis server, it uses the RESP protocol to format the command. The server parses the RESP message, executes the command, and sends a RESP-formatted response back to the client.
Example
Let's consider a simple GET command:
```
*2\r\n$3\r\nGET\r\n$3\r\nkey\r\n
```
Server response (if the key exists):
```
$5\r\nvalue\r\n
```
Server response (if the key does not exist):
```
$-1\r\n
```
Each of these is translated so that it is readable by removing the `\r\n`.
One example with a data type
Hashes
This is the most used data type, Hashes are maps between string fields and string values, which are perfect for representing objects.
```
*4\r\n$4\r\nHSET\r\n$6\r\nmyhash\r\n$4\r\nname\r\n$5\r\nAlice\r\n
```
Server response
```
:1\r\n
```
Getting hash field
Client request:
```
*3\r\n$4\r\nHGET\r\n$6\r\nmyhash\r\n$4\r\nname\r\n
```
Server response:
```
$5\r\nAlice\r\n
```
## Conclusion
RESP plays a crucial role in Redis's performance and efficiency, providing a simple yet powerful way to encode and decode messages between clients and servers. Understanding RESP and how it handles different Redis data types can help you make the most of Redis in your applications. Whether you're dealing with strings, lists, hashes, or sets, RESP ensures that communication is fast, reliable, and easy to work with.
## What we learned
1. How does the RESP help us serialize Redis command over the network and help us achieve the performance?

These... | 0 | 2024-06-19T05:06:10 | https://dev.to/motadata123/why-advanced-persistent-threats-important-in-cyber-security-5eff | advancedpersistentthreats, apt | One of the largest risks in contemporary cyber space is an [Advanced Persistent Threat](https://www.motadata.com/it-glossary/advanced-persistent-threat-apts/) or APT. These specific and advanced attack surfaces when you least think of them and greatly harm organizations, a country’s security, and its intellectual assets. Some cyber-attacks are done with keeping specific goals in mind while others focus just creating uncertainty and terror.
In this blog, we will introduce APTs and its outline of characteristics that really hits the cornerstone of the issue, stages of attack and several examples. We will gain deeper access to the nitty-gritty and also consider the significance of guarding the web applications, mobile applications and other important data centers against APTs and how the risks can be prevented with the right security measures being in place.
## What are Advanced Persistent Threats (APTs)?
APTs are sophisticated and protracted forms of cyber-attacks, more specifically meaning a targeted attack with possibly extended persistence. Unlike conventional malware, which targets systems and seeks to infect as many computers as possible, APTs are conducted more over a long period, and the goal is to compromise the system to acquire the security information.
APTs are social engineering techniques that are well orchestrated and catered for involving pro Greek threat actors. These attacks can be directed at any targeted network, be it government- related organizations or big companies and even sophisticated and strategic equipment systems. The primary objectives of advanced persistent threat are to establish continual presence in the target network, which enables the attacker extend steal information from the network and control system without being obvious.
The single specialty of APTs is their persistency. The offenders are also willing to commit adequate time to see that they have accomplished their goals. They do this by using attack methods that include spear phishing emails, zero-day vulnerability, malicious software and watering hole attacks that give them a foothold in the target network. Once inside, they roam horizontally and try to escalate their privileges, in this way obtaining access to other portions of the network and, respectively, to other types of data.
## Why are Advanced Persistent Threats are so Important?
APTs are of utmost importance in the field of cyber security due to their potential impact on national security, intellectual property, and organizations' competitive advantage. These targeted and prolonged attacks can lead to the theft of sensitive data, compromise critical infrastructure, and disrupt business operations. APTs are often orchestrated by well-funded nation-state cybercriminal groups, making them a significant concern for governments and organizations worldwide.
## Sophistication and Motivation
APTs are very complicated acts that are executed by ultramodern cybercriminals or those with a lot of funding, and this includes nations’ hired hackers. Criminal attackers have an aim that they want to achieve hence the attacks are made.
The attacks could be designed to steal trade secrets or research data from large corporations to gain a competitive edge in certain industries. They can also be of a political nature, that is, the attacker aims to use the obtained information for political purposes, including putting pressure on certain political forces or to gather sensitive information on them.
Other threat actors, like the members of organized crime groups, can conduct APTs with the motive of their financial rewarding. They focus on obtaining information that will be useful in unlawful activities, including identity theft
The coordination and motivation of advanced persistent threat attackers extend the groups which pose a threat to the security of nations and business entities. Thus, understanding the threats that APTs represent for governments and businesses can never be overemphasized, just as practical protective measures against these kinds of groups should be implemented.
## Devastating Impact
Advanced Persistent Threats (APTs) pose severe consequences with far reaching risks that encompass organizations and national security. Here are some of the potential consequences of APT attacks:
• **Theft of intellectual property:** Lost of important information such as trade secrets, research data and other unique techniques are likely to be stolen by APTs. If the attackers gain supervisory control, it will significantly impact competitive position and the corporation’s ability to innovate.
• **Loss of competitive advantage:** In the context of APT attacks, if a competitor gets access to huge amounts of valuable customer details, it can erode the organization’s competitive position in the market.
• **Compromise of national security:** Advanced Persistent Threat attacks that intrude into government agencies and information technology-based critical infrastructure systems will have negative impacts on the country’s security. While the stealing of information or even interrupting services is damaging in its own right, having sensitive information stolen or critical services interrupted can be a danger to citizens.
• **Damage to reputation and trust:** APT attacks, if successful, can therefore compromise an organization's security systems and its operations, resulting in negative consequences such as loss of credibility and customer trust. These can have far reaching implications on the shareholders, employees, customers and the organization in general as it leads to monetary losses, illegal data acquisition, etc.
Therefore, even if it is a junk email, be very apprehensive. It is important for smaller companies or larger organizations to understand and recognize the severity and the impact of advanced persistent threat attacks and take proactive measures to prevent and mitigate these threats.
## Evolving Threat
Cyber attacks have increased in number. These threats are impacting small and large organizations as they are evolving over an extended period. In addition, the earlier ones are getting more advanced over a long period of time. APT groups are the ones in the lead regarding such improvements and they are always ready to shift their tactics to penetrate a security layer.
The advanced persistent threat attack groups are affiliated and cooperation as well as information exchange drives their abilities forward, also complicates the positioning of organizations against them. Electronic means include the use of revolutionary tools and tactics, including zero day or unknown exploits and complex avoidance tactics to establish and maintain a foothold on target networks.
Along with the changes in the attack paradigms, APT groups also look for new technologies and areas to exploit. Whenever new technologies are introduced to organizations and businesses, including [cloud computing](https://www.motadata.com/blog/types-of-cloud-computing-services-deployment-models/) and Internet of Things (IoT) devices, APT groups are always assumed to take advantage of any vulnerability in the system.
The mandatory characteristic of the threat posed by APTs is that organizations cannot adopt a static approach to protection against it. This is consisting of use of appropriate security measures such as the improved [access control](https://www.motadata.com/it-glossary/access-control-list/), current software updates, and regular scanning of the traffic of the network for any signs of threat.
## How to Protect Against Advanced Persistent Threats (APTs)?
Minimizing and preventing exposures to Advanced Persistent Threat (APTs) entail the use of various layers of protection that are technical as well as organizational. Since it has both, it is important to understand the best practices to protect against APTs.
• **Implement defense in depth:** Develop multiple layers of defense which may include firewalls, IDS, access control measures, and other layers that may help to ward off APT more effectively.
• **Continuous monitoring and threat intelligence:** In this regard, the following steps should be implemented: Statically analyze network traffic and user’s activity to identify any signs of malicious activity. In addition, one should monitor threat intelligence sources for the latest emerging advanced persistent threat tactics and techniques to be prepared for any cases.
• **Vulnerability management:** To minimize the exposure to deceit by APT attackers, be careful to periodically sweep and remediate your systems and application software for possible weak spots.
• **Endpoint protection:** Use advanced endpoint protection solutions that may help identify APT attacks on the generic level and on particular devices in particular.
• Employee education and awareness: Immunize employees aware about threats/anomalies faced by Enterprise APT and typical methods like phishing emails to con them.
## Defense in Depth
A strong defense in-depth is the best way the network can be defended against advanced persistent threats. It entails the use of secure layers to put up defenses that can counteract the attacks in question. Here are some key components of defense in depth:
• **Access control:** There is also a need to maintain strict security measures of access control like authentication by using several methods and access control with minimal security permissions on sensitive systems and databases.
• **Network segmentation:** Isolate you network by organizing it into subnets and control data transfer between these subnets. This can assist in limiting the APT attack’s effects or its ability to gain further unauthorized access within the network.
• **Security monitoring:** Use IDPS and SIEM to identify an ongoing APT attack and apply corresponding countermeasures in near real time.
• **Incident response planning:** This should include the outline of the general and tactical measures for handling an APT attack as is explained below 0. This encompasses methods of dealing with containment, investigating, and recovery processes.
## Continuous Monitoring and Threat Intelligence
Security solutions that involve threat intelligence along with around the clock monitoring are foundations of APT protection strategies. Here's how these measures can help protect against APTs
• **Threat intelligence:** Use threat intelligence to follow up on the newest and most innovative compromises by APT attacks. The given data can aid organizations in their efforts to confront advanced persistent threat attacks.
• **Continuous monitoring:** Packet sniff and analyze the request strings and responses of users constantly to identify any unusual activity that is characteristic of an APT attack. This entails the practice of high technology security analytics to be in place.
• **Endpoint protection:** To some extent, this endpoint protection solutions can also detect and independently counter APT attacks targeting separate devices. These encompass issues such as next-generation antivirus, behavior-based protection, and endpoint detection and response or EDR.
By combining threat intelligence with [continuous monitoring](https://www.motadata.com/blog/continuous-monitoring/) and proactive vulnerability management, organizations can enhance their ability to detect, respond to, and mitigate the risks associated with APT attacks.
## Conclusion
In conclusion, Advanced Persistent Threats (APTs) pose a significant risk to cybersecurity due to their sophistication, motivation, and devastating impact. As these threats continue to evolve, implementing robust defense strategies such as Defense in Depth and Continuous Monitoring with Threat Intelligence is crucial to safeguarding sensitive data and systems. Stay vigilant and proactive in fortifying your security measures to mitigate the risks posed by APTs. | motadata123 |
1,893,143 | Navigating Client-Side Routing | Hello readers, I'm Simone, currently enrolled in the Academi Xi Front-End Web Development: Transform... | 0 | 2024-06-19T05:03:22 | https://dev.to/simoneveitch/navigating-react-client-side-routing-5cnb | Hello readers,
I'm Simone, currently enrolled in the Academi Xi Front-End Web Development: Transform course. I'm in the midst of Phase 2, which focuses on React.
After completing Phase 1, which laid the foundation for Javascript, Phase 2 introduced me to the world of React.
It took some adjustment moving from a vanilla Javascript mindset, to suddenly having to think in components, states and side effects. The biggest challenge I faced, however, was client-side routing.
I’ll tell you why.
Prior to being introduced to client-side routing the two main concepts that I was introduced to were useState and useEffect. While it took some time to get my head around these two hooks, they are more straightforward in their use.
Client-side routing introduced multiple concepts that I had to get my head around in a very brief amount of time. You need to understand all the components that make up client-side routing to get it to work on your web application and be able to troubleshoot issues that you will no doubt face when trying this out for the first time.
But first things first, why is client-side routing important? Client-side routing enables smooth navigation between different pages on your web application without making a full request to the server. This is beneficial as it leads to a faster user experience when navigating between pages.
In vanilla Javascript you will typically need to click on a link that points to a different HTML file, ie, loading an entirely new HTML document. To do this the browser has to send a request to the server for the new page, which can lead to a less smooth user experience.
Alternatively, to avoid a full page reload using vanilla Javascript, you can use Javascript to manipulate the DOM and update the content, but as it requires manual handling of the DOM it is more error prone.
While I personally find using vanilla Javascript for page navigation more simple and approachable as an aspiring front-end web developer, the benefits of using React and client-side routing outweigh those of vanilla JavaScript (if, and only if, you are building an application where page navigation is necessary).
React uses a single-page application approach, and handles routing within this, which allows for a more seamless navigation. This approach avoids full page reloads, and navigation is instead managed by React components.
Below I will take you through some key concepts relating to client-side routing with code examples from my Phase 2 React web application project.
**Getting started**
To get started using client-side routing you will need to install React Router, which is a library that handles routing in React applications. Without this you won’t have the components and hooks required to manage navigation and URL changes.
In your terminal add the following to install React Router
```
npm install react-router-dom
```
Then, import it into your application in the component where you need to enable client-side routing.
```
import React from "react";
import ReactDOM from "react-dom";
import { BrowserRouter as Router } from "react-router-dom";
```
Let me break this down before we continue.
BrowserRouter is the top level component that enables routing. It uses the HTML5 history API to manage the browser’s history stack, which is what allows you to navigate through your app using the browser's back and forward buttons.
Next, you need to wrap your components and routes in `<Router>` to be able to define routes and navigate between them without refreshing the page. You typically just need to do this in your top-level Router component, which in my case is index.js. You only need to do this once, as the `<Router>` component provides routing context to all its child components.
```
import React from "react";
import ReactDOM from "react-dom";
import { BrowserRouter as Router } from "react-router-dom";
import App from "./Components/App";
import './index.css';
ReactDOM.render(
<Router>
<App />
</Router>,
document.getElementById("root")
);
```
Now that we have that set up, we can start working on our routing context.
In my web application I have two main components that work with navigation, App and NavBar.
Starting with my App component, I import all the components that I want to navigate to.
```
import NavBar from "./NavBar";
import DirectoryList from "./DirectoryList";
import ResultsList from "./ResultsList";
import Contact from "./Contact";
import Tips from "./Tips";
import Home from "./Home";
import Footer from "./Footer";
```
I then wrap all my routes in `<Switch>`. The purpose of switch is that it ensures that only the first matching `<Route> `is rendered. This prevents multiple components from rendering at the same time, which is important to ensure a smooth user experience.
Next I wrap each component that will sit on its own page, ie, each component that I want the user to be able to navigate to, as though it’s its own page in `<Route>`. `<Route>` defines the paths and the components to render for those paths. For example, when the URL in my code is `/directorylist`, the DirectoryList component is rendered.
```
return (
<div className="app-container">
<NavBar />
<Switch>
<Route exact path="/directorylist">
<DirectoryList list={list}/>
</Route>
<Route exact path="/tips">
<Tips />
</Route>
<Route exact path="/contact">
<Contact onAddOrganisation={handleAddOrganisation}/>
</Route>
<Route exact path="/">
<Home />
</Route>
<Route
path="/results/:category"
render={({ match }) => (
<ResultsList category={match.params.category} />
)}
/>
</Switch>
<Footer />
</div>
);
```
There are a few props that make `<Route>` work as it does. You can see them all in use here:
```
<Route exact path="/directorylist">
<DirectoryList list={list}/>
</Route>
```
Path is the URL path to match, ‘exact’ ensures that the route matches exactly, preventing partial matches. This is especially important if you have a path that is `“/”` like I do for the Home component. And then there is the component to render, when the path matches, which in the above example is my DirectoryList component.
That concludes the routing context in my App component. In summary, the `<Router>` set up manages the routing context and determines which components to render based on the current URL.
This isn’t where the story ends though, next you need to set up the UI elements for navigating between the different routes, without that your users won’t be able to actually navigate to the different components. In my case, I manage this in my NavBar component.
**Navigation interface**
To start off, I again first need to import the component that enables rendering.
If you don’t plan to do any styling based on active routes you can import `<Link>`, but as I am, I imported `<NavLink>` instead. Both components render an anchor tag `(<a>)` and update the URL without causing a page reload. The difference is that with `<Navlink>` you can define styling for the active route.
```
import { NavLink } from "react-router-dom";
```
Next, I add all the NavLinks that will appear in my navigation bar.
```
return (
<div className={`navbar ${navBackground ? "navbar-scrolled" : ""}`}>
<button className={`hamburger ${menuOpen ? "open" : ""}`} onClick={toggleMenu}>
<div className="line"></div>
<div className="line"></div>
<div className="line"></div>
</button>
<div className={`nav-links ${menuOpen ? "open" : ""}`}>
<NavLink to="/" exact className="navlink" activeClassName="active">
Home
</NavLink>
<NavLink to="/directorylist" exact className="navlink" activeClassName="active">
Directory
</NavLink>
<NavLink to="/tips" exact className="navlink" activeClassName="active">
Tips
</NavLink>
<NavLink to="/contact" exact className="navlink" activeClassName="active">
Contact
</NavLink>
</div>
</div>
);
}
export default NavBar;
```
To break down the elements in the code above, the NavBar component provides a user interface for navigation, which is imported into my App components that renders that component. The NavLinks are used to create navigable links that allow users to switch between different routes, and it also enables me to add styling to the link when it matches the current URL.
I can then define the active style in my CSS, providing a better user experience as the user will know which route is active.
The screenshot below is from my web application, and when a route is active, ie, is the page the user is currently on, the nav element has an underline.
And that is that.
**Final words**
In summary, I need both the Router setup in my App component for routing logic and the NavLink setup in my NavBar component for navigation UI, to ensure that users can interact with my app and navigate between different pages smoothly.
These are the most fundamental parts of client-side routing. There are other hooks that are important, like useParams and useLocation, but I won’t go in to those here.
Thanks for reading.

In the realms of computer science and software engineering, certain concepts and principles play crucial roles in ensuring systems' robustness, reliability, and predictability. One such concept is [idempotency](https://dev.to/keploy/understanding-white-box-testing-an-in-depth-exploration-3ml), a term that, while seemingly esoteric, has profound implications in various areas, including web services, databases, and functional programming. This article delves into the definition, importance, and practical applications of idempotency, aiming to provide a comprehensive understanding of its role in modern computing.
What is Idempotency?
Idempotency is a property of certain operations that denotes their ability to be applied multiple times without changing the result beyond the initial application. Formally, an operation fff is idempotent if, for all inputs xxx, applying fff to xxx multiple times yields the same result as applying fff once. Mathematically, this is represented as:
f(f(x))=f(x)f(f(x)) = f(x)f(f(x))=f(x)
This definition implies that no matter how many times the operation is executed, the outcome remains constant after the first application.
The Importance of Idempotency
The significance of idempotency in computing can be appreciated across various dimensions:
1. Reliability: Idempotent operations ensure that systems can handle retries gracefully. In distributed systems, where network failures and partial system failures are common, retrying operations without fearing unintended consequences is crucial.
2. Safety: In web services, making HTTP requests idempotent means that if a client sends the same request multiple times, the server's state remains unchanged after the first request. This is particularly important for operations like payment processing or resource creation.
3. Consistency: Idempotency helps maintain data consistency. For instance, in database operations, an idempotent transaction can be retried multiple times in the event of a failure, ensuring that the database remains in a consistent state.
4. Simplicity: Idempotent operations simplify error handling logic. Since the result of applying an operation multiple times does not change, developers can avoid complex checks and conditions in their code.
Idempotency in Web Services
Idempotency is a critical concept in the design of RESTful web services. The HTTP specification defines certain methods as idempotent:
• GET: This method is inherently idempotent, as it is used to retrieve resources without modifying them.
• PUT: Used to update or create resources, PUT requests are idempotent because applying the same update multiple times does not change the resource state beyond the initial application.
• DELETE: While logically idempotent (deleting a resource that is already deleted does not change the state), it can have side effects such as triggering notifications.
• HEAD and OPTIONS: These methods are also idempotent as they are used for metadata retrieval and preflight requests, respectively.
Implementing Idempotency
The implementation of idempotency depends on the context and specific requirements of the operation. Here are some common strategies:
1. Idempotency Keys: For operations like resource creation or transaction processing, clients can generate unique idempotency keys. The server stores these keys and the results of the operations. Subsequent requests with the same key return the stored result without re-executing the operation.
2. Resource Versioning: In update operations, using versioning can ensure idempotency. Clients include the resource version in their requests, and the server only applies changes if the version matches the current state.
3. Conditional Requests: HTTP provides mechanisms like If-Match and If-None-Match headers to make requests conditional. This can help ensure that operations are applied only when certain conditions are met, thus maintaining idempotency.
4. State Checks: Before performing an operation, the system can check the current state to determine if the operation has already been applied. This is common in systems where the state can be queried efficiently.
Idempotency in Functional Programming
In functional programming, idempotency is often associated with pure functions. A pure function, by definition, does not produce side effects and always returns the same result given the same input. While not all pure functions are idempotent, idempotency is a valuable property in the context of functional programming because it ensures predictability and reliability.
For example, consider a function that sanitizes input strings by removing whitespace:
haskell
Copy code
sanitize :: String -> String
sanitize = trim . replaceMultipleSpaces
-- Assuming 'trim' and 'replaceMultipleSpaces' are both idempotent functions
If both trim and replaceMultipleSpaces are idempotent, then sanitize is also idempotent. Applying sanitize multiple times to the same input string yields the same result as applying it once.
Challenges and Considerations
While idempotency offers numerous benefits, implementing it can be challenging. Some operations are inherently non-idempotent, such as generating unique identifiers or processing user input that changes with each request. In such cases, ensuring idempotency requires careful design and often involves trade-offs.
Moreover, idempotency can have performance implications. For example, maintaining idempotency keys or resource versions might require additional storage and processing overhead. Balancing these costs with the benefits of idempotency is a critical consideration in system design.
Conclusion
Idempotency is a fundamental concept that enhances the reliability, safety, and simplicity of computing systems. By ensuring that operations can be repeated without unintended consequences, idempotency plays a crucial role in the robustness of web services, the consistency of databases, and the predictability of functional programming. Understanding and implementing idempotency effectively can significantly improve system design and operation, making it an indispensable tool in the arsenal of software engineers and computer scientists.

## 1. Introduction
### What is a Forward Proxy?
A forward proxy is an intermediary server that forwards client requests to other servers. It acts as a gateway between the client and the internet, making requests on behalf of the client and returning the responses to the client. This setup allows the proxy to manage and control access to resources, provide anonymity, and optimize performance.
### Benefits of Using a Forward Proxy
- **Privacy and Anonymity**: By masking the client's IP address, a forward proxy can enhance privacy.
- **Access Control**: Proxies can be used to control access to certain websites or services.
- **Caching**: They can cache frequently requested content to improve load times and reduce bandwidth usage.
- **Security**: Proxies can filter traffic and block malicious content.
---
## 2. Getting Started
### Prerequisites
Before setting up a forward proxy, ensure you have the following:
- A server or virtual machine with a Linux-based operating system (Ubuntu, CentOS, etc.).
- Root or sudo access to the server.
- Basic understanding of networking and command-line operations.
### Choosing the Right Proxy Software
There are several proxy software options available. Two of the most popular are Squid and Nginx. Squid is highly configurable and widely used, especially for caching purposes, while Nginx is known for its high performance and is often used as a web server or reverse proxy.
---
## 3. Setting Up a Forward Proxy with Squid
### Installation
To install Squid on Ubuntu, follow these steps:
```bash
sudo apt update
sudo apt install squid -y
```
For CentOS:
```bash
sudo yum install squid -y
```
### Basic Configuration
After installation, the main configuration file is located at `/etc/squid/squid.conf`. Open this file in your preferred text editor.
```bash
sudo nano /etc/squid/squid.conf
```
To set up a basic forward proxy, add the following lines:
```conf
http_port 3128
acl localnet src 192.168.1.0/24 # Replace with your network range
http_access allow localnet
http_access deny all
```
### Advanced Configuration
To enhance the functionality and security of your Squid proxy, consider the following configurations:
1. **Caching**: Configure caching to improve performance.
```conf
cache_dir ufs /var/spool/squid 100 16 256
maximum_object_size 4096 KB
```
2. **Access Control**: Define ACLs to control access.
```conf
acl allowed_sites dstdomain .example.com
http_access allow allowed_sites
```
3. **Logging**: Enable and configure logging for monitoring.
```conf
access_log /var/log/squid/access.log
cache_log /var/log/squid/cache.log
```
### Testing Your Proxy
After configuring Squid, restart the service:
```bash
sudo systemctl restart squid
```
To test your proxy, configure your web browser or client to use the proxy server's IP address and port (3128).
---
## 4. Setting Up a Forward Proxy with Nginx
### Installation
To install Nginx on Ubuntu, use the following commands:
```bash
sudo apt update
sudo apt install nginx -y
```
For CentOS:
```bash
sudo yum install nginx -y
```
### Basic Configuration
Open the Nginx configuration file:
```bash
sudo nano /etc/nginx/nginx.conf
```
Add the following configuration to set up a basic forward proxy:
```conf
http {
server {
listen 8080;
location / {
proxy_pass http://$http_host$request_uri;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
}
```
### Advanced Configuration
To enhance Nginx's proxy capabilities, consider these advanced configurations:
1. **SSL/TLS**: Secure the proxy with SSL/TLS.
```conf
server {
listen 443 ssl;
ssl_certificate /path/to/cert.pem;
ssl_certificate_key /path/to/key.pem;
location / {
proxy_pass http://$http_host$request_uri;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
```
2. **Load Balancing**: Distribute requests across multiple servers.
```conf
upstream backend {
server backend1.example.com;
server backend2.example.com;
}
server {
listen 8080;
location / {
proxy_pass http://backend;
}
}
```
### Testing Your Proxy
After configuring Nginx, restart the service:
```bash
sudo systemctl restart nginx
```
Configure your web browser or client to use the proxy server's IP address and port (8080) to test the setup.
---
## 5. Enhancing Your Proxy Setup
### Security Measures
- **Authentication**: Require users to authenticate before using the proxy.
For Squid, add:
```conf
auth_param basic program /usr/lib/squid/basic_ncsa_auth /etc/squid/passwd
auth_param basic children 5
auth_param basic realm Squid proxy-caching web server
auth_param basic credentialsttl 2 hours
acl authenticated proxy_auth REQUIRED
http_access allow authenticated
```
For Nginx, use:
```conf
location / {
auth_basic "Restricted";
auth_basic_user_file /etc/nginx/.htpasswd;
proxy_pass http://$http_host$request_uri;
}
```
- **IP Whitelisting**: Only allow specific IPs to use the proxy.
For Squid:
```conf
acl allowed_ips src 192.168.1.100/32
http_access allow allowed_ips
```
For Nginx:
```conf
location / {
allow 192.168.1.100;
deny all;
proxy_pass http://$http_host$request_uri;
}
```
### Performance Tuning
- **Squid**: Increase cache size and memory usage.
```conf
cache_mem 256 MB
maximum_object_size_in_memory 512 KB
```
- **Nginx**: Optimize worker processes and connections.
```conf
worker_processes auto;
worker_connections 1024;
```
---
## 6. Common Use Cases
### Caching Web Content
Caching helps reduce bandwidth usage and improves response times for frequently accessed resources. Squid is particularly effective for this purpose.
### Access Control and Monitoring
Proxies can restrict access to certain websites or services, making them useful in corporate environments to enforce internet usage policies.
### Anonymity and Privacy
By masking the client's IP address, a forward proxy can help users maintain anonymity online and protect their privacy.
---
## 7. Troubleshooting and Maintenance
### Common Issues
- **Connection Refused**: Ensure the proxy server is running and the correct ports are open.
- **Authentication Problems**: Verify the authentication configurations and user credentials.
- **Slow Performance**: Check for network issues, optimize configurations, and ensure adequate server resources.
### Regular Maintenance Tasks
- **Log Monitoring**: Regularly check log files for unusual activity.
- **Software Updates**: Keep your proxy software up to date to ensure security and performance.
- **Configuration Backups**: Maintain backups of your configuration files to quickly restore in case of issues.
---
## 8. Conclusion
Setting up a forward proxy can significantly enhance your network's functionality, security, and performance. Whether you choose Squid or Nginx, the steps outlined in this guide provide a comprehensive approach to configuring and managing a forward proxy. By understanding and implementing these configurations, you can effectively control network traffic, improve user privacy, and optimize resource usage.
Remember, the key to a successful proxy setup is continuous monitoring and maintenance. Regularly update your configurations, monitor logs, and stay informed about best practices and security updates. With these practices, your forward proxy will serve as a robust tool for managing and securing your network. | iaadidev |

1,892,095 | Clonador y Fusionador de Playlists para Spotify | Hace aproximadamente 2 años tuve la oportunidad de conocer proyectos en React, pero fue hacia finales... | 0 | 2024-06-19T04:40:24 | https://dev.to/garcodas/clonador-y-fusionador-de-playlists-para-spotify-k45 | react, spotify, vite, vercel | Hace aproximadamente 2 años tuve la oportunidad de conocer proyectos en React, pero fue hacia finales del año pasado cuando comencé a perfeccionar mis habilidades en esta tecnología.
Aunque todavía estoy en proceso de aprendizaje, he decidido compartir una serie de proyectos que he desarrollado en mi cuenta de [Github.](https://github.com/garcodas/) Durante este tiempo, mi objetivo ha sido crear proyectos funcionales que no solo beneficien mi crecimiento como desarrollador, sino que también puedan ser útiles para la comunidad en general. Recientemente, mientras escuchaba una playlist en Spotify, noté varias canciones que no me gustaban. Esto me llevó a plantearme la siguiente pregunta:
**¿Existirá una opción dentro de Spotify, en la que pueda clonar una playlist pública y que pueda eliminar canciones?**
La respuesta corta es: **No**
Debido a que solo el dueño de la playlist tiene el control total sobre su contenido, incluyendo la capacidad de agregar, eliminar o reorganizar canciones.
Entonces decidí investigar cómo funciona Spotify y descubrí que tienen una [API](https://aws.amazon.com/es/what-is/api/) a la cual puedes conectarte de forma **gratuita** después de cierta configuración. Con esta información, desarrollé la siguiente [SPA (Single Page Application).](https://digital55.com/blog/que-son-single-page-application-spa-desarrollo-elegido-por-gmail-linkedin/)
La versión más reciente del repositorio está publicada en vercel, puedes acceder desde acá [https://spotify-playlists-mu.vercel.app/](https://spotify-playlists-mu.vercel.app/)
## ¿Como funciona?
**Iniciar sesión con Spotify.**
> **¿Porque debo acceder con mi cuenta de Spotify?**
> Cuando clonas listas de reproducción, estas se guardan en tu cuenta, por lo que te conviertes en el administrador. Esto significa que no solo se agregarán a tu biblioteca, sino que también podrás gestionarlas a tu gusto. Está sesión quedará únicamente en tu navegador.
Al momento de que presiones el botón iniciar con Spotify, si no tienes ingresada tu sesión te pedirá que accedas.
Después de que ingreses sesión te pedirá que apruebes unos permisos, estos permisos servirán para crear playlists, agregar canciones a playlists y eliminar canciones.
Si otorgas los permisos correspondientes, la aplicación te dará un mensaje de Bienvenida y se habilitarán los inputs para colocar los links de las playlists.
**Clonar playlist**
Para clonar una playlist basta con poner el link de la playlist pública, si deseas eliminar una canción presiona el botón "Agregar Canción" y entonces las canciones que coloques en esa lista se excluirán de tu nueva playlist.
**Fusionar Playlists**
Durante el desarrollo de la aplicación web, se me ocurrió la idea de poder combinar las canciones de 2 o más playlists. Para esto, creé una sección donde se pueden ingresar los enlaces de las playlists públicas. Utilizando el [API de Spotify](https://developer.spotify.com/documentation/web-api), la aplicación crea una nueva playlist y agrega todas las canciones de las playlists especificadas.
## Explicando el código
Antes de continuar, cabe mencionar que el código está disponible de forma gratuita en mi [Github.](https://github.com/garcodas/spotify-playlists)
El link del repositorio es [https://github.com/garcodas/spotify-playlists](https://github.com/garcodas/spotify-playlists)
Debido a que es una SPA (Single Page Application), en el repositorio solo se encuentra la parte del frontend, que se conecta con el API de Spotify.
Para su desarrollo, se utilizaron las siguientes bibliotecas:
- React con versión 18.2.0
- React Router con versión 6.23.1
- Vite con versión 5.2.0
Para la realización de solicitudes se utilizó la biblioteca:
- Axios con versión 1.7.2
Para la realización y validación de formularios se utilizaron las bibliotecas:
- Zod con versión 3.23.8
- React Hook Form con versión 7.51.5
También se utilizó una biblioteca de componentes llamada [shadcn/ui](https://ui.shadcn.com/) la cual utiliza [tailwindcss](https://tailwindcss.com/) para estilizar los componentes.
En conclusión, esta SPA que he desarrollado te permite combinar canciones de varias playlists de Spotify, facilitando la creación de nuevas listas personalizadas. Todo el código está disponible en mi repositorio de GitHub, donde puedes encontrar la parte del frontend que se conecta con el API de Spotify.
Si estás interesado en aprender más sobre React o deseas contribuir haciendo mejoras al proyecto, te animo a explorar el repositorio y enviar tus Pull Requests. Estaré encantado de revisar y colaborar en tus aportes. Además, Estoy abierto a recibir comentarios constructivos sobre mi código para seguir avanzando en esta tecnología. Tu participación es muy valiosa para seguir mejorando esta herramienta.

Dois dos paradigmas mais influentes e amplamente utilizados são o paradigma procedural e o paradigma orientado a objetos. Cada um possui suas próprias filosofias, abordagens e benefícios e entender suas características é matéria primordial seja você um programador iniciante ou um engenheiro levantando requisitos para um novo projeto.
## Orientação a objetos
O paradigma orientado a objetos consiste na criação de _objetos_, que podem ser descritos, de forma simplória, como _instâncias_ de _classes_.
As classes definem propriedades (atributos) e comportamentos (métodos) que os objetos podem ter. A ideia é modelar as representações do mundo real em termos de objetos que interagem entre si.
Sua prática promove a reutilização de código através de conceitos como injeção de dependência permitindo a criação de sistemas complexos de forma modular. O encapsulamento, herança e polimorfismo são os pilares fundamentais deste paradigma.
## Procedural
No paradigma procedural, a estrutura do programa gira em torno de _funções_ e _procedimentos_. Aqui, a principal preocupação é a sequência de passos que devem ser seguidos para alcançar um determinado resultado.
O código é segmentado em funções que podem receber dados de entrada, processar ou transformá-los, e então retornar um resultado. A reutilização de código é alcançada através da criação de funções genéricas.
Este paradigma facilita a criação de programas mais simples e diretos, adequados para tarefas que podem ser divididas em etapas sequenciais claras. No entanto, pode se tornar complexo e difícil de gerenciar à medida que o programa cresce, especialmente em projetos maiores onde modularidade e abstração são essenciais.
## Conclusão
Em conclusão, tanto o paradigma procedural quanto o orientado a objetos têm suas vantagens e limitações. A escolha entre eles deve ser guiada pelas necessidades específicas do projeto, pela familiaridade da equipe e pelos requisitos de desempenho e manutenção. | lvteixeira | |
1,893,136 | C++ 的 string 物件到底佔幾個位元組？ | 最近剛好遇到一個問題, 才發現 C++ 中的 std::string 配置的空間在不同版本的編譯器並不一樣, 以底下的程式碼為例： #include<iostream> using... | 0 | 2024-06-19T04:33:41 | https://dev.to/codemee/c-de-string-wu-jian-dao-di-zhan-ji-ge-wei-yuan-zu--42ea | cpp, string | 最近剛好遇到一個問題, 才發現 C++ 中的 [`std::string`](https://en.cppreference.com/w/cpp/string/basic_string) 配置的空間在不同版本的編譯器並不一樣, 以底下的程式碼為例：
```cpp
#include<iostream>
using namespace std;
int main(void){
string s = "hello";
cout << "sizeof(s):" << sizeof(s) << endl;
return 0;
}
```
如果是在 gcc 4.9.3(原始的 [Dev-C++ 5.11](https://sourceforge.net/projects/orwelldevcpp/) 停留在 gcc 4.9.2, 若是 EMBARCADER 接手維護的 [Dev-C++ 6.3](https://www.embarcadero.com/free-tools/dev-cpp) 則是停留在 gcc 9.2.0), 執行結果如下：
```
sizeof(s):8
```
但若是在 gcc 5.1 開始, 執行結果如下：
```
sizeof(s):32
```
你可以[在這裡](https://godbolt.org/z/MnjYvz475)自由查看不同編譯器的結果。
這主要是因為在 gcc 5.1 之前, `std::string` 的實作會動態配置一塊動態變化大小的記憶體, 裡面存放字串目前長度、可容納字串長度以及字串內容, 字串物件裡面只有一個指向這塊記憶體中字串起始位址的指位器, 因此佔用了紀錄 64 位元系統位址的 8 個位元組。[整體結構](https://github.com/gcc-mirror/gcc/blob/6503c21eb9098470636326bae601a11ee4cc488e/libstdc%2B%2B-v3/include/bits/basic_string.h#L70)如下：
```
+-----------------
| size_t capacity
+-----------------
| size_t size
+-----------------
s | szie_t refcount
+---------- +-----------------
| char *ptr ------> |"hello"
+---------- +-----------------
```
若修改字串內容, 超過可容納的最長長度, 就會重新配置整塊記憶體。其中**共用計數**是配合 **(Copy on Write, 簡稱 CoW, 修改時才複製)** 機制運作。字串共用計數預設是 0, 如果複製字串物件給另一個字串物件時, 這兩個字串物件會共用同一塊記憶體, 並遞增共用計數。等到其中一個字串物件要修改字串內容時, 會檢查共用計數, 若共用計數大於 0, 就會配置新的一塊記憶體給要修改字串的物件, 並將原本的共用計數減 1, 讓兩個字串物件使用不同區塊的記憶體。如此可以避免不必要的動態記憶體配置動作, 如果字串物件沒有修改內容, 就會持續共用記憶體, 而不需要配置新的記憶體。
但是到了 [gcc 5.1](https://isocpp.org/blog/2015/04/gcc-5.1-released) 開始, 引入了 [small string optimization(簡稱 SSO, 短字串最佳化)](https://devblogs.microsoft.com/oldnewthing/20230803-00/?p=108532) 的實作方式, 現在字串物件存放的內容變多了, 裡面會有：
```
s
+----------------
| chat *ptr ----------+
+---------------- |
| size_t size |
+---------------- |
| buf (16 bytes) <----+
+----------------
```
`size_t` 和指位器都是 8 位元組, 所以總共佔 32 個位元組。當字串長度沒有超過 15 個字元時, 就會把字串直接儲存在 `buf` 中, 免去動態配置記憶體的時間, 加快處理短字串的效能。由於 `buf` 是固定的 16 個位元組, 所以可容納字串的最長長度就是 15(扣除結尾的 '\0')。
如果字串長度超過 15 時, 就會實際動態配置記憶體來存放, 這時結構會變成：
```
s
+----------------- +----------
| chat *ptr -------------> | buf
+----------------- +----------
| size_t size
+-----------------
| size_t capacity
+-----------------
| padding(8 bytes)
+-----------------
```
原本用來存放短字串的區域就會改成用來存放可容納字串的最長長度了。也由於實作方式的差異, 所以 gcc 5.1 開始就不使用 CoW 機制了。
我們可以透過以下的程式碼來驗證：
```cpp
#include <iostream>
using namespace std;
int main(void) {
string s = "hello, world";
cout << "sizeof(s):" << sizeof(s) << endl;
cout << "&s:" << &s << endl;

}
```
這裡透過條件編譯以不同的方式解譯字串物件的結構, 在 gcc 4.9.3 的執行結果如下：
```
sizeof(s):8
&s:0x7ffe2bd9f7b0
s.data():0x7652b8
s.capacity():12
s.size():12
*ptr:hello, world
refcount:2
capacity:12
size:12
sizeof(s):8
&s:0x7ffe2bd9f7b0
s.data():0x7662f8
s.capacity():24
s.size():18
*ptr:this is a new book
s2 refcount:1
s refcount:0
capacity:24
size:18
```
你可以看到一開始會依照字串長度配置記憶體, 從 s 物件的位址與實際儲存字串的位址也可以知道這兩個位址相差很遠, 顯示實際儲存字串的區塊是動態配置, 你也可以看到字串的長度與可容納最長長度都是 12。你也可以透過指位器運算, 經由剛剛解釋的結構取得個別資訊。我們也特亦將此字串物件複製兩次, 因此可以看到共用計數為 2, 表示有另外兩個字串物件共用這塊記憶體。
一旦將字串內容改成比較長的內容, 就可以看到因為重新配置記憶體, 所以實際儲存字串內容的位址改變了, 而且可容納字串的最長長度也不一樣, 變成 24 了。也因為修改字串, 所以會配置新的區塊存放, 你可以看到原本區塊的共用計數會減 1, 從 2 變為 1, 表示現在只有 1 的字串物件共用原本的區塊, 而新配置的區塊上共用計數則是 0。
如果是 gcc 5.1, 結果如下：
```
sizeof(s):32
&s:0x7ffda2e7f6d0
s.data():0x7ffda2e7f6e0
s.capacity():15
s.size():12
*ptr:hello, world
size:12
*ptr:hello, world
sizeof(s):32
&s:0x7ffda2e7f6d0
s.data():0x1a59ec0
s.capacity():30
s.size():18
*ptr:this is a new book
size:18
capacity:30
```
一開始因為是使用物件內固定大小的區塊儲存字串, 所以你可以看到 s 物件的位址與實際儲存字串內容的位址就相差 16, 如同前面解說的結構, 而且因為可存放區域的大小是固定的, 所以可容納字串的最長長度就是 15。你同樣可以利用指位器運算, 依循剛剛解說的結構取得個別資料。
一旦將字串長度加長到超過 15, 就會迫使程式動態配置記憶體, 你可看到 s 物件的位址不變, 但是實際儲存字串的位址已經改變了, 完全不在 s 物件內。現在可容納字串的最長長度也不再是 15, 而是新配置的記憶體大小 30 了。

1,893,048 | Decoupling Your Applications with AWS SQS: A Deep Dive | Decoupling Your Applications with AWS SQS: A Deep Dive In today's dynamic tech... | 0 | 2024-06-19T03:02:35 | https://dev.to/virajlakshitha/decoupling-your-applications-with-aws-sqs-a-deep-dive-1elm | 
# Decoupling Your Applications with AWS SQS: A Deep Dive
In today's dynamic tech landscape, building scalable and resilient applications is paramount. A common architectural pattern that facilitates this is asynchronous communication, allowing different components of your application to interact without direct coupling or immediate dependencies. This is where message queues come in, acting as intermediaries for seamless data flow. In the AWS ecosystem, Simple Queue Service (SQS) excels in this domain.
### Introduction to AWS SQS
Amazon SQS is a fully managed message queuing service designed to send, store, and receive messages between software components at any volume, without losing messages or requiring the availability of other services. SQS effectively decouples your application's components, enabling them to operate independently and enhancing fault tolerance.
### Core Concepts:
* **Messages:** The fundamental units of data transmitted via SQS, capable of carrying up to 256 KB of text in various formats (JSON, XML, etc.).
* **Queues:** Logical containers holding messages. Producers send messages to queues, and consumers retrieve messages from them.
* **Producers:** Applications or components sending messages to SQS queues.
* **Consumers:** Applications or components receiving messages from SQS queues for processing.
* **Visibility Timeout:** The duration a message is hidden from other consumers after being retrieved. This timeout ensures that a message is processed only once.
* **Dead-Letter Queues (DLQ):** A designated queue to capture messages that were not successfully processed. This is crucial for debugging and error handling.
### Use Cases for SQS:
1. **Microservices Choreography:** In a microservices architecture, SQS orchestrates communication by acting as a central message bus. Services communicate asynchronously via messages, promoting loose coupling and independent deployments.
**Example:** Imagine an e-commerce platform. When an order is placed, the order service sends a message to an SQS queue. The inventory service, subscribed to this queue, receives the message and updates the stock levels. This approach eliminates direct dependencies between services, allowing them to scale and evolve autonomously.
2. **Asynchronous Task Processing:** SQS handles tasks that don't require immediate responses, allowing your application to remain responsive.
**Example:** A social media platform can use SQS for image processing. When a user uploads an image, the application can queue a message for thumbnail generation. A background worker then processes this message asynchronously, freeing the main application thread from handling this time-consuming task.
3. **Buffering and Load Leveling:** SQS acts as a buffer between components with varying processing speeds. It prevents downstream services from being overwhelmed by sudden spikes in traffic.
**Example:** A news website experiencing a surge in traffic during a breaking news event can use SQS to buffer incoming user requests. This queue absorbs the traffic spikes, and web servers can then process requests at their own pace, preventing outages.
4. **Event-Driven Architectures:** SQS seamlessly integrates with other AWS services like EventBridge and SNS to build event-driven systems.
**Example:** A stock trading application can use SQS to process real-time market data. When a stock price changes significantly, a message is sent to an SQS queue. Trading algorithms subscribed to this queue can then react to these price fluctuations swiftly and automatically.
5. **Cross-Platform Integration:** SQS facilitates communication between applications written in different languages or hosted on different platforms.
**Example:** A mobile gaming app (written in Swift) can communicate with a backend server (running on Node.js) by exchanging messages through SQS. This allows for seamless data synchronization and interaction between different parts of the game ecosystem.
### Alternatives to AWS SQS
1. **RabbitMQ:** An open-source message broker known for its reliability and feature set. It supports various messaging protocols and offers flexible routing options.
2. **Apache Kafka:** Designed for high-throughput, low-latency streaming data. It's often used for building real-time data pipelines and event streaming platforms.
3. **Google Cloud Pub/Sub:** Google Cloud's fully managed real-time messaging service. Like SQS, it offers scalability and reliability for asynchronous communication.
### Conclusion
AWS SQS provides a robust and scalable solution for building decoupled, resilient, and highly available applications. Its ease of use, pay-as-you-go pricing, and seamless integration with other AWS services make it a compelling choice for architects and developers. Whether you are modernizing a legacy application or building a cloud-native solution, understanding and leveraging SQS can significantly enhance your application's architecture and performance.

**Advanced Use Case: Building a Serverless Image Processing Pipeline**
Let's imagine you're tasked with building an image processing pipeline for a media sharing application. Users should be able to upload images of any size, and your system needs to generate thumbnails, apply watermarks, and store the processed images efficiently. Here's how you can leverage AWS SQS in conjunction with other services to create a robust and scalable solution:
**Architecture:**
1. **Image Upload:** Users upload images to an S3 bucket.
2. **Trigger Lambda Function:** The S3 upload event triggers a Lambda function.
3. **Enqueue Message:** The Lambda function creates messages containing image metadata (S3 object key, desired transformations) and sends them to an SQS queue.
4. **Image Processing Workers:** A fleet of EC2 instances or ECS containers (using Fargate for serverless) run a worker process. These workers poll the SQS queue for messages.
5. **Image Processing:** Upon receiving a message, a worker downloads the original image from S3, performs the required image manipulations using a library like ImageMagick, and stores the processed images back into a separate S3 bucket.
6. **Dead-Letter Queue:** A Dead-Letter Queue (DLQ) is configured on the main SQS queue to capture any messages that were not processed successfully, allowing for error handling and retries.
**Advantages:**
* **Scalability and Cost-Effectiveness:** The serverless nature of Lambda and SQS allows the system to scale on-demand based on the volume of image uploads. You only pay for the resources you consume.
* **Fault Tolerance:** If an image processing worker fails, messages will remain in the SQS queue until another worker picks them up, ensuring no data loss.
* **Decoupling:** The use of SQS decouples image uploading from processing, allowing each component to operate independently and scale autonomously.
**Key Considerations:**
* **SQS Queue Configuration:** Use a standard queue for high throughput or a FIFO queue if message ordering is critical (e.g., applying a sequence of image transformations).
* **Concurrency Control:** Configure appropriate concurrency settings on Lambda and your worker processes to manage the rate of image processing and prevent overloading downstream systems.
* **Monitoring and Alerting:** Implement monitoring (using CloudWatch) and set up alerts to be notified of any processing backlogs or errors.
This advanced use case demonstrates how SQS, combined with other AWS services, can form the backbone of sophisticated, scalable, and fault-tolerant applications.

1,893,132 | Mastering CSS Variables: A Beginner's Guide to Custom Properties | Hey there! If you're looking to make your CSS cleaner, more efficient, and a whole lot more fun, then... | 0 | 2024-06-19T04:29:31 | https://dev.to/delia_code/mastering-css-variables-a-beginners-guide-to-custom-properties-1gdk | webdev, css, beginners, programming | Hey there! If you're looking to make your CSS cleaner, more efficient, and a whole lot more fun, then you're in the right place. Today, we're diving into the world of CSS Variables, also known as CSS Custom Properties. These little gems are a game-changer in how we write and manage styles in modern web development. So, let’s break down what CSS variables are, why they're awesome, and how you can start using them today.
## What Are CSS Variables?
CSS Variables allow you to store values that you want to reuse throughout your stylesheet. You can define a value once, and then reference it in multiple places. This is super handy for maintaining large stylesheets or themes.
### Syntax of CSS Variables
Defining a CSS variable is simple. You typically declare it within the `:root` pseudo-class, which makes it available globally across your stylesheet:
```css
:root {
--main-bg-color: coral;
}
```
Then, you can use this variable elsewhere in your CSS by wrapping it in `var()`:
```css
body {
background-color: var(--main-bg-color);
}
```
## Advantages of Using CSS Variables
1. **Maintainability**: Change the value in one place, and it updates everywhere. This is a lifesaver for projects where consistent theming is crucial.
2. **Scoping**: Unlike preprocessor variables (like those in SASS or LESS), CSS variables can be scoped locally to elements. This means you can define and override values for specific areas of your webpage.
3. **Runtime Changes**: CSS variables can be manipulated in real-time through JavaScript, making them perfect for dynamic themes or user-generated style changes.
## Practical Tips and Tricks
### Responsive Design
You can use CSS variables to simplify your responsive design workflow. For instance, you can define font sizes that change with the viewport:
```css
:root {
--font-small: 12px;
--font-large: 16px;
}
@media (min-width: 768px) {
:root {
--font-small: 14px;
--font-large: 18px;
}
}
body {
font-size: var(--font-small);
line-height: var(--font-large);
}
```
### Theming
Creating themes is a breeze with CSS variables. Define a set of variables for each theme, and switch between them easily:
```css
:root {
--primary-color: blue;
--secondary-color: green;
}
.dark-theme {
--primary-color: midnightblue;
--secondary-color: darkgreen;
}
.container {
color: var(--primary-color);
background-color: var(--secondary-color);
}
```
### Interacting with JavaScript
Adjusting CSS variables with JavaScript adds an interactive dimension to your site:
```javascript
document.documentElement.style.setProperty('--primary-color', 'purple');
```
## Common Pitfalls and How to Avoid Them
- **Browser Support**: While most modern browsers support CSS variables, some older versions (like Internet Explorer) do not. Consider using a fallback or a polyfill if older browser support is crucial.
- **Overuse**: It's tempting to turn every value into a variable. However, use them judiciously for values that genuinely need reuse or real-time manipulation.
CSS Variables open up a world of possibilities for writing DRY, maintainable, and dynamic CSS. They can help you manage large stylesheets with ease, create themed designs without a hassle, and even let you tweak styles on the fly with JavaScript. So go ahead, give them a try, and see how they can improve your styling workflow!
Remember, the key to mastering CSS Variables is practice and experimentation. Start small by integrating them into a project or two, and soon you'll be on your way to becoming a CSS pro!

CSS reset offers a clean slate by removing all default styles, while normalize.css preserves useful defaults and standardizes inconsistencies. Both techniques enhance cross-browser consistency, improve development efficiency, and contribute to a better user experience. | srijan_karki | |

I have been a Software Engineer for the last 8 years. Although I was interested in Machine Learning and AI in college, I never had the opportunity or patience to pursue that passion.
Now, when the ML field grew exponentially in 2023, with the latest innovations in large language models, I have a terrible longing for the road not taken. What if I choose to study Machine learning? What if I decided to pursue my career as an ML engineer? What would have happened if I had gone to graduate school?
Being stupidly optimistic, I decided to learn about Machine learning independently.
Partly this crazy idea was also partly inspired by Scott Young’s [ted talk video](https://www.youtube.com/watch?v=piSLobJfZ3c&ab_channel=TEDxTalks) titled: **“Can you get an MIT education for $2,000?”**. Scott talks about how he finished a computer science degree just by following MIT curriculums and self studying. After. which he was also able to land a entry level position.
I Googled around for self-taught ML Engineers. I got quite a few mixed reviews from Reddit. At this point, I am not sure whether it is possible to be a self-taught ML engineer. The only way to figure it out was to try to attempt it myself. However, I am optimistic.
I plan on taking courses from open-source courses available online, such as MIT Open Courseware and Coursera. The goal is to teach myself everything I can within the next 6~8 months.
To be clear, my goal here is not to build the next groundbreaking model. I simply want to see if I can get an interview for a junior-level Machine Learning or Data Engineering job after this experiment. This is purely an experiment and I am not trying to transition into a role in ML. So, if you are interested, join me on my journey. I plan on journaling about it weekly and documenting everything that I study.
Another disclaimer: I am not starting from scratch. As I did my undergraduate degree in Computer Engineering, I understand some of the fundamentals needed to pull this off. I have solid background knowledge of single and multivariable calculus, linear algebra, and statistics, as I took these courses in school about a decade ago.
I am going to follow this learning roadmap. However, I am going to omit many of these courses. I am going to focus mainly on Machine Learning, Deep learning, and Transformer Architecture.

For the first 4 weeks I am going to focus on finishing [Machine Learning Specialization](https://www.coursera.org/specializations/machine-learning-introduction?utm_campaign=WebsiteCourses-MLS-MiddleButton-mls-launch-2022&utm_medium=institutions&utm_source=deeplearning-ai) from Andrew Ng. The goal is to speed run through these first 3 courses and get a solid understanding of the basics.
That is all for today, see you in a week or two. | shadid12 |

They ensure that incoming and outgoing data packets reach the appropriate service (e.g., web server, email client) by specifying a unique number, typically ranging from 0 to 65535. | aritra-iss |
