One of the standout features of Next.js is its integration with Node.js runtime. This allows developers to execute JavaScript code on the server side, enabling full stack development within the same project. With Next.js, you can write both frontend and backend code, streamlining the development process.
## Full Stack Development Capabilities
Next.js enables full stack development, meaning you can handle both the client-side and server-side logic within a single project. This reduces the complexity of managing separate backend projects and allows for seamless integration between frontend and backend components.
## Server-Side Rendering (SSR)
Server-side rendering (SSR) is a technique that renders web pages on the server and sends the fully rendered HTML to the client. This improves performance and search engine optimization (SEO). Next.js simplifies SSR, making it easy to implement and configure.
## Static Site Generation (SSG)
Static Site Generation (SSG) is another powerful feature of Next.js. It allows you to pre-render pages at build time, creating static HTML files that are served to the client. This results in faster load times and better performance, especially for content-heavy pages.
## Improved Performance and SEO
By leveraging SSR and SSG, Next.js significantly improves the performance and SEO of web applications. Pre-rendered pages load faster and are more easily indexed by search engines, leading to better visibility and user experience.

1,885,449 | ꜱᴄᴀʟɪɴɢ ᴀɴᴅ ɴᴏʀᴍᴀʟɪᴢɪɴɢ ᴅᴀᴛᴀ ꜰᴏʀ ᴍᴀᴄʜɪɴᴇ ʟᴇᴀʀɴɪɴɢ ᴍᴏᴅᴇʟꜱ | Scaling and Normalizing Data for Machine Learning Models 🐍🤖 In the world of machine... | 0 | 2024-06-12T08:55:33 | https://dev.to/kammarianand/ling-n-nrliing-r-hin-lrning-l-4bij | machinelearning, datascience, python, data | ## Scaling and Normalizing Data for Machine Learning Models 🐍🤖
In the world of machine learning, scaling and normalizing your data are crucial preprocessing steps before feeding it into models. Proper scaling ensures that each feature contributes equally to the result, while normalization often improves the performance of the algorithm. In this post, we'll explore these concepts in detail, focusing on methods provided by the `scikit-learn` module. We'll also provide code snippets and formulas for clarity.
## Why Scale and Normalize ❓
1. **Improves Model Performance**: Many machine learning algorithms perform better when features are on a similar scale. For instance, algorithms like SVM and KNN are sensitive to the scales of the features.
2. **Faster Convergence**: Gradient descent converges faster with scaled features.
3. **Reduces Bias**: Unscaled features can cause bias in the model towards features with a larger range.
## Scaling Techniques
### Standardization (Z-score Normalization)
Standardization scales the data to have a mean of zero and a standard deviation of one.
The formula is: `z = (x - μ) / σ`
Where:
- `x` is the original value
- `μ` is the mean of the feature
- `σ` is the standard deviation of the feature
#### Code Example
```python
from sklearn.preprocessing import StandardScaler
import numpy as np
# Sample data
data = np.array([[1, 2], [3, 4], [5, 6], [7, 8]])
# Standardizing the data
scaler = StandardScaler()
standardized_data = scaler.fit_transform(data)
print("Standardized Data:\n", standardized_data)
```
output
```python
Standardized Data:
[[-1.34164079 -1.34164079]
[-0.4472136 -0.4472136 ]
[ 0.4472136 0.4472136 ]
[ 1.34164079 1.34164079]]
```
### Min-Max Scaling (Normalization)
Min-Max scaling scales the data to a fixed range, usually [0, 1].
The formula is: `x' = (x - x_min) / (x_max - x_min)`
Where:
* x is the original value
* x_min is the minimum value of the feature
* x_max is the maximum value of the feature
#### Code Example
```python
from sklearn.preprocessing import MinMaxScaler
import numpy as np
# Sample data
data = np.array([[1, 2], [3, 4], [5, 6], [7, 8]])
# Normalizing the data
scaler = MinMaxScaler()
normalized_data = scaler.fit_transform(data)
print("Normalized Data:\n", normalized_data)
```
output
```python
Normalized Data:
[[0. 0. ]
[0.33333333 0.33333333]
[0.66666667 0.66666667]
[1. 1. ]]
```
## Normalization Techniques
### L2 Normalization
L2 normalization scales each data point such that the Euclidean norm (L2 norm) of the feature vector is 1.
The formula is: `x' = x / ||x||_2`
Where ||x||_2 is the L2 norm of the feature vector.
#### Code Example
```python
from sklearn.preprocessing import Normalizer
# Sample data
data = np.array([[1, 2], [3, 4], [5, 6], [7, 8]])
# Normalizing the data using L2 norm
normalizer = Normalizer(norm='l2')
l2_normalized_data = normalizer.fit_transform(data)
print("L2 Normalized Data:\n", l2_normalized_data)
```
output
```python
L2 Normalized Data:
[[0.4472136 0.89442719]
[0.6 0.8 ]
[0.6401844 0.76822128]
[0.65850461 0.75257669]]
```
### L1 Normalization
L1 normalization scales each data point such that the Manhattan norm (L1 norm) of the feature vector is 1. The formula is:
formula : `x' = x / ||x||_1`
Where `||x||_1` is the L1 norm of the feature vector.
#### Code Example
```python
from sklearn.preprocessing import Normalizer
# Sample data
data = np.array([[1, 2], [3, 4], [5, 6], [7, 8]])
# Normalizing the data using L1 norm
normalizer = Normalizer(norm='l1')
l1_normalized_data = normalizer.fit_transform(data)
print("L1 Normalized Data:\n", l1_normalized_data)
```
output
```python
L1 Normalized Data:
[[0.33333333 0.66666667]
[0.42857143 0.57142857]
[0.45454545 0.54545455]
[0.46666667 0.53333333]]
```
example code :
```python
from sklearn.datasets import load_iris
from sklearn.preprocessing import MinMaxScaler
from sklearn.linear_model import LogisticRegression
from sklearn.model_selection import train_test_split
# Load the iris dataset
data = load_iris()
X, y = data.data, data.target
# Normalize the features
scaler = MinMaxScaler()
X_normalized = scaler.fit_transform(X)
# Split the data into training and testing sets
X_train, X_test, y_train, y_test = train_test_split(X_normalized, y, test_size=0.3, random_state=42)
# Fit a logistic regression model
model = LogisticRegression()
model.fit(X_train, y_train)
# Evaluate the model
score = model.score(X_test, y_test)
print(f"Model Accuracy: {score:.2f}")
```
output : `Model Accuracy : 0.91`
**Conclusion**
Scaling and normalizing your data are fundamental steps in preparing it for machine learning models. scikit-learn provides convenient and efficient tools for both scaling and normalization. Here’s a quick summary of the methods discussed:
- Standardization: Adjusts the data to have a mean of 0 and a standard deviation of 1.
- Min-Max Scaling: Scales the data to a fixed range, usually [0, 1].
- L2 Normalization: Scales the data so that the L2 norm of each row is 1.
- L1 Normalization: Scales the data so that the L1 norm of each row is 1.
→ By correctly applying these techniques, you can improve the performance and convergence of your machine learning models.

This lead to inconsistencies and errors, especially when working sensitive data user roles. That's where the code snippet below comes in - clever to dynamically update enum in database, ensuring data integrity and flexibility in your application.
## The Problem: Stale Enum Values
```php
namespace App\Enums;
enum UserRoles: string
{
case ADMIN = 'admin';
case MODERATOR = 'mod';
case USER = 'user';
}
public static function values(): array
{
return array_column(self::cases(), 'value');
}
```
Imagine you have a roles table in your database, where each role is defined by an enum column name. Initially, you defined the enum values as `['admin', 'mod', 'user']`. However, as your application evolves, you need to add new roles, they won't be recognized by the database, leading to errors and inconsistencies.
So let's consider a scenario where you want to add two new roles, `editor` and `guest`, to the existing enum values. Without this dynamic update mechanism, you would need to manually modify the database to include these new values, which can be error-prone and time-consuming.
## The Solution: Dynamic Enum Updates
**UserRoles.php**
```php
namespace App\Enums;
enum UserRoles: string
{
case ADMIN = 'admin';
case MODERATOR = 'mod';
case USER = 'user';
case EDITOR = 'editor';
case GUEST = 'guest';
}
// ... reset of the codes ...
```
**UpdateUserRolesEnum.php**
```php
namespace App\Console\Commands;
use App\Enums\UserRoles;
use Illuminate\Console\Command;
use Illuminate\Support\Facades\DB;
class UpdateUserRolesEnum extends Command
{
protected $signature = 'user-roles-enum:update';
protected $description = 'Update enum values in the database';
public function handle()
{
$enumValues = UserRoles::values();
DB::statement("ALTER TABLE roles MODIFY name
ENUM('" . implode("','", $enumValues) . "')"
);
$this->info('Enum values updated successfully.');
}
}
```
The code snippet above provides a solution to this problem by dynamically updating the enum values in the database. Here's how it works:
The **`UpdateUserRolesEnumCommand`** command retrieves the current enum values from the **`UserRoles`** enum using the values() method.
The command then updates the enum values in the database using a raw SQL query, modifying the name column to include the new enum values.
Run this process every time you add a new case additionally, extract statements inside the handle() method when adding through the dashboard. The code that the enum values in the database are always up-to-date and in sync with the code. This approach has several benefits:
With this code, you can simply add the new roles to the **UserRoles** enum, and the command will take care of updating the database automatically. The resulting enum values in the database would be **`['admin', 'moderator', 'user', 'editor', 'guest']`**.
In conclusion, the code snippet above provides a valuable solution to the problem of stale enum values in your database.

## What is Test-driven development (TDD) and why it is Important?
Test-driven development (TDD) is a software development approach that emphasizes writing tests before writing the actual code. It follows a cycle of writing a failing test, writing the code to make the test pass, and then refactoring the code to improve its design.
The importance of test-driven development can be seen in several aspects:
* Improved Code Quality: TDD helps ensure that the code meets the desired requirements by writing tests that define the expected behavior.
* Faster Debugging: By writing tests first, developers can catch and fix issues early in development.
* Design Improvement: TDD promotes better software design. Since tests are written before the code, developers are forced to think about the design and structure of their code upfront.
* Better Collaboration: TDD encourages collaboration between developers and stakeholders. By defining the expected behavior through tests, developers, and stakeholders can have a shared understanding of the requirements.
* Documentation: The tests written in TDD act as living documentation for the codebase. They provide insights into the intended behavior of the code and serve as a reference for future development or maintenance.
* Continuous Integration and Deployment: TDD fits well with continuous integration and deployment practices. With a solid test suite, teams can automate the testing process and ensure the code remains functional and bug-free throughout the development lifecycle.
* Increased Confidence: With a comprehensive suite of tests, developers gain confidence in their code.
> In summary, test-driven development is important because it improves code quality, speeds up debugging, enhances software design, boosts confidence, promotes collaboration, serves as documentation, and aligns with modern development practices. By following TDD, developers can build robust and reliable software systems.

1,885,444 | next.js 14 server action, API route vs separate backend | Next.js API Routes in Next.js 14: Pros: Simplicity: Unified Codebase: Serverless... | 0 | 2024-06-12T08:54:33 | https://dev.to/robiulman/nextjs-14-server-action-api-route-vs-separate-backend-4266 | nextjs, backend, webdev, javascript |
### Next.js API Routes in Next.js 14:
Pros:
1. Simplicity:
2. Unified Codebase:
3. Serverless Architecture:
4. Performance
Cons:
1. Limited Flexibility:
2. Vendor Lock-in:
3. Scalability Concerns:
- In Next.js 14, API routes have been rewritten using React Server Components, which provide a more efficient and streamlined approach to handling server-side rendering (SSR) and server-side operations.
- API routes can now leverage the new Server Actions feature, which allows you to write server-side code directly within your React components, making it easier to integrate server-side logic with the frontend.
- With Server Actions, you can perform server-side operations like querying databases, interacting with APIs, or processing data, all within the same component file.
- The new architecture in Next.js 14 improves performance and reduces the overhead of server-client communication by minimizing the need for client-side JavaScript and allowing for more efficient rendering on the server.
- API routes and Server Actions are well-suited for handling lightweight to moderate server-side operations and can leverage the benefits of Next.js's built-in features like static generation, server-side rendering, and middleware.
### Separate Backend (Express, Django, Spring, etc.):
Pros:
1. Flexibility:
2. Scalability:
3. Specialized Frameworks:
4. Security and Compliance:
Cons:
1. Increased Complexity:
2. Deployment and Infrastructure:
3. Latency:
- Using a separate backend application built with frameworks like Express, Django, or Spring is still a viable option in Next.js 14, especially for applications with complex server-side requirements or when you need to leverage the full capabilities of a dedicated server-side framework.
- A separate backend allows for better separation of concerns, scalability, and flexibility in choosing the appropriate technology stack for the backend.
- Complex server-side operations like real-time communication (WebSockets), background jobs, and advanced database operations can be more easily implemented and managed within a dedicated backend application.
- With a separate backend, you have more control over server-side caching, load balancing, and horizontal scaling, which may be necessary for highly scalable and resource-intensive applications.
- However, using a separate backend introduces additional complexity in setting up and managing two separate applications (frontend and backend), as well as potential challenges in integrating the frontend and backend, such as handling CORS and authentication.
In Next.js 14, the decision between using Next.js API routes with Server Actions or a separate backend largely depends on the complexity of your application's server-side requirements and the expertise of your development team.
If your application has relatively simple to moderate server-side operations and can leverage the benefits of Next.js's built-in features, using Next.js API routes and Server Actions can provide a more streamlined and efficient development experience, with better integration between the frontend and backend.
On the other hand, if your application requires complex server-side logic, advanced server-side features, or if you need to leverage the full capabilities of a dedicated server-side framework, using a separate backend application may be the better choice. This approach allows for better scalability, flexibility, and separation of concerns, but at the cost of increased complexity in setup, deployment, and integration.
It's also worth noting that you can adopt a hybrid approach, where you use Next.js API routes and Server Actions for lightweight operations, while offloading more complex server-side logic to a separate backend application. This allows you to leverage the benefits of both architectures and mitigate their limitations based on your application's specific needs.
Ultimately, the decision should be based on a careful evaluation of your application's requirements, the complexity of your server-side operations, the expertise of your development team, and the scalability and performance demands of your project.

1,885,443 | Larry Connors RSI2 Mean Reversion Strategy | From Many friends asked me to write a grid and market maker strategy,But I generally... | 0 | 2024-06-12T08:51:11 | https://dev.to/fmzquant/larry-connors-rsi2-mean-reversion-strategy-nac | strategy, fmzquant, trading, cryptocurrency | ## From
Many friends asked me to write a grid and market maker strategy,But I generally decline directly. Regarding these strategies, first of all, you must have a strong mathematical knowledge, at least a doctor of mathematics.
In addition, high-frequency quantitative trading is more about financial resources, such as the amount of funds and broadband network speed.
The most important thing is that these violate my understanding of the trading.
Is there any other way to do high-frequency trading? Today we will introduce this RSI mean regression strategy based on Larry Connors.
## Introduction
The RSI2 strategy is a fairly simple mean regression trading strategy developed by Larry Connors, mainly operate during the price correction period.
When RSI2 falls below 10, it is considered over-selling and traders should look for buying opportunities.
When RSI2 rises above 90, it is considered over-buying and traders should look for selling opportunities.
This is a fairly aggressive short-term strategy aimed at participating in continuing trends. It is not intended to identify the main top or bottom of the price.
## Strategy
There are four steps to this strategy.
## Use the long-term moving average to determine the main trends
Connors recommends the 200-day moving average. The long-term trend rises above the 200-day moving average, and declines below it.
Traders should look for buying opportunities above the 200-day moving average and short selling opportunities below it.
## Select the RSI range to determine buying or selling opportunities
Connors tested RSI levels between 0 and 10 to buy and 90 to 100 to sell. (Based on closing price)
He found that when the RSI fell below 5, the return on buying was higher than the return below 10. The lower the RSI, the higher the return on subsequent long positions.
Correspondingly, when the RSI is higher than 95, the return on short selling is higher than the return on above 90.
## Regrading of the actual buying or short selling orders and their placing order time
Connors advocates the "close" method. Waiting for the closing price to open positions gives the trader more flexibility and can increase the winning rate.
## Set the appearance position
Where should stop-loss be?
Connors does not advocate the use of stop loss. In a quantitative test of hundreds of thousands of transactions, Connors found that the use of stop-loss actually "damaged" performance.
But in the example, Connors recommends to stop-loss long positions above the 5-day moving average and short positions below the 5-day moving average.
Obviously, this is a short-term trading strategy that can exit quickly, or consider setting up trailing stop loss or adopting SAR synthetic stop loss strategy.
Sometimes the market does indeed price drift upwards. Failure to use stop loss may result in excess losses and large losses.
This requires traders to consider and decide.
## Verification
The chart below shows the Dow Jones Industrial Average SPDR (DIA) and 200-day SMA (red), 5-period SMA (pink) and 2-period RSI.
When the DIA is higher than the 200-day SMA and the RSI (2) falls to 5 or lower, a bullish signal appears.
When the DIA is below the 200-day SMA and the RSI (2) rises to 95 or higher, a bearish signal will appear.
In these 12 months, there are 7 signals, 4 bullish and 3 bearish.
Among the 4 bullish signals, DIA rose by 3 of 4 times, which means that these signals may be profitable.
Among the four bearish signals, DIA fell only once.
After a bearish signal in October, DIA broke the 200-day moving average.
Once the 200-day moving average is exceeded, RSI2 will not fall to 5 or lower to generate another buying signal.
As for profit and loss, it will depend on the level of stop-loss and take- profit.
The second example shows Apple (APL), which is above the 200-day moving average for most of the time period.
During this period, there are at least ten buying signals.
Since APL saw a sawtooth decline from late February to mid-June 2011, it is difficult to avoid the loss of the first five indicators.
As the APL rose in a jagged pattern from August to January, the last five signals performed much better.
As can be seen from the chart, many signals are very early.
In other words, Apple fell to a new low after the initial buy signal and then rebounded.
## Conclusion
The RSI2 strategy provides traders with the opportunity to participate in continuing trends.
Connors pointed out that traders should buying at price retracement point, not breakouts point.
also, traders should sell at oversold rebounds, not price support breakouts point.
This strategy is in line with his philosophy.
Even though Connors' tests indicate that stop loss affects performance, it is prudent for traders to develop exit and stop loss strategies for any trading system.
When the situation becomes over-buying or a stop loss is set, the trader can exit the long position.
Similarly, when conditions are oversold, traders can withdraw from short positions.
Use these ideas to enhance your trading style, risk-reward preferences and personal judgment.
## FMZ source code display
Connors' strategy is relatively simple, it is simply written in M language. (Everyone can understand)
Because the original strategy design target was US stocks, the 200-day moving average was used as a reference.
In the violently volatile digital currency market, it is just suitable for short-term value return.
So we adjusted the time range to 15 minutes, and the MA period was 70, and use 1 times the leverage for backtest.

//When it is less than the moving average，rsi<10 open long position，rsi>90 close long position
AUTOFILTER;
```

## Backtest effect
After a systematic backtest, we see that the overall winning rate of the RSI strategy is high. Its performance satisfied us.
The maximum retracement occurs at 312, and extreme market conditions will do more harm to the strategy of shock return.
## Tweaking
After RSI2 rise above 95, the market can continue to rise;
After RSI2 drops below 5, the market can continue to fall.
To correct this situation, we may need to involve OHLCV analysis, intraday chart patterns, other momentum indicators, etc.
After RSI2 rise above 95, the market can continue to rise and it is dangerous to establish a short position.
Traders may consider filtering this signal by waiting for RSI2 to return below its centerline 50.

1,885,441 | How do you add page links and manage changes to a page by changing a single file in PHP? | Today I have learned to add page links in PHP project. And also know how to manage files that... | 0 | 2024-06-12T08:50:07 | https://dev.to/ghulam_mujtaba_247/how-to-add-page-links-and-to-manage-pages-a6a | webdev, beginners, programming, php | Today I have learned to add page links in PHP project. And also know how to manage files that contains the data of pages.
## Important must read
- Firstly you have to go to website https:/www.tailwindui.com to check different layouts or design of home pages to create like that.
- As you have chosen your design, at right corner of design there is an option to copy the code. Copy it and then follow next steps.
## Diving in code
In vs code project(version 1.
90 at the time of working)
, we need following dependencies:
- HTML5 basic code
- CSS for styling pages
- PHP page creation
## On VS Code Side
- Firstly open the software that is installed on your system and then start a new project named `index.view.php` then input ! and hit enter to get HTML5 basic code .
- Go to the `<body>` tag and paste the code you copied from the Tailwind website. When you paste the code, you'll notice comments at the beginning of the copied code."
```html
<!--html
This example requires updating your template:
```
<html class="h-full bg-gray-100">
<body class="h-full">
```
-->
```
Add these in code as follows:
```html
DOCTYPE html>
<html lang="en" class="h-full bg-gray-100">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body class="h-full">
```
## Buttons on web page with link
- The next section of code, copied from the website, contains a list of buttons - 'Home', 'About', 'Contact Us', and 'Testing' - that appear on the output screen. These buttons contain links that direct the user to the corresponding next page, where relevant data is available.
A page link is present in anchor tag `<a> <\a>` of HTML as:
```html
<a href="/" class="rounded-md bg-gray-900 px-3 py-2 text-sm font-medium text-white" aria-current="page">Home</a>
<a href="/abput.php" class="rounded-md px-3 py-2 text-sm font-medium text-gray-300 hover:bg-gray-700 hover:text-white">About</a>
<a href="/contact.php" class="rounded-md px-3 py-2 text-sm font-medium text-gray-300 hover:bg-gray-700 hover:text-white">Contact Us</a>
<a href="/testing.php" class="rounded-md px-3 py-2 text-sm font-medium text-gray-300 hover:bg-gray-700 hover:text-white">Testing</a>
```
- The button styling is also applied to the anchor tag with the link, using the `:hover` pseudo-class to change the button's state when pressed.
- After adding this code, a blank screen appears when debugging and running the code. To resolve this issue, add the `index.view.php` file with a starting PHP tag (`<?php`) at the top.
## Second file
This file is named as `index.php`
```php
<?php
require"Index.view.php";
```
Now the output will show.
I hope that you have clearly understand everything.
### Manage page by changing single file
To make changes to a page by modifying a single file, copy the navigation bar code within the `<nav></nav>` tags. Create a new directory and a new file named `nav.php` within it, and paste the code into this file. To utilize this file for the rest of the project, include its address in the same place from where the original code was copied.
Here's a summary of the steps:
1. Copy the navigation bar code within the `<nav></nav>` tags.
2. Create a new directory and a new file named `nav.php` within it.
3. Paste the copied code into the `nav.php` file.
4. Include the address of the `nav.php` file in the same place where the original code was copied.
```php
<?php require('particles/nav.php') ?>
```
By doing this, you can manage changes to the navigation bar from a single file (`nav.php`) and have the updates reflected across all pages that include it.
I hope that you have understand it. | ghulam_mujtaba_247 |

Ok, but what exactly are AI agents?
In a nutshell, agents (or AI bots) are small programs that can perform tasks like generating content or collecting data autonomously. The concept has been around since the early days of computing, but it has recently gained momentum with a new breed of large language models (LLMs) like GPT-4.
This article will teach you how to build your own AI agents in Taskade. You'll also learn how to train them to "think" like you, so you can relax and enjoy your coffee while agents do the heavy lifting. ☕️
💡 Here's a tl;dr of what we 're going to discuss
- Basics of AI agents and AI agent builders.
- Components of AI agents like memory, knowledge, and skills.
- Process of building, training, and deploying agents.
- Benefits of integrated AI agent builders.
- Impact of AI agent builders on a and individuals.
🦾 What Are AI Agent Builders?
------------------------------
Chat-based generative AI tools like ChatGPT or Bing are cool. But they work on a mostly ad-hoc basis. You formulate a problem, ask a question, and get a response. Simple.
But what if the problem comes up frequently or you need to perform certain tasks on a daily basis?
This is where AI agent builders come into play.
An AI agent builder is a standalone or integrated platform that lets you build, train, and deploy customized agents without technical know-how. And it's way cooler than it sounds.
An AI agent is made up of several components:
- 🧠 Short-term and long-term memory that stores the context of tasks it's working on.
- 💡 General knowledge of the large language model (LLM) that powers the agent.
- 👹 A unique "personality" and tone of voice that's reflected in the agent's responses.
- 🛠️ A set of specialized skills, e.g. the ability to browse the web.
AI agent builders give you full control over the nitty-gritty of your assistants. You decide what tasks they specialize in, how they respond to questions, and how much they know.
Of course, there is much more happening behind the scenes. But the whole point of agent builders is to seamlessly integrate [autonomous task management](https://www.taskade.com/blog/autonomous-task-management/) into existing workflows.
🐑 + 🤖 Introducing Taskade as an AI Agent Builder
--------------------------------------------------
Taskade is a productivity platform that blends project management features with smart tools powered by advanced AI. It's also the only solution with fully integrated agent-building capabilities.
(psst... that's Taskade down below. Isn't that a thing of beauty? 🤩)
[Taskade AI agents](https://www.taskade.com/ai/agents) live where you work ---not in some walled-garden platform, separate from your workflow, but inside your projects, folders, and workspaces, where all the action is.
Agents running inside your projects can automate a ton of different tasks:
- ✏️ Generate content
- 📈 Track progress
- 🌐 Browse the web
- 📥 Fetch information
- 🗓️ Schedule events
- 🗃️ Organize tasks
- And much more...
Customized AI agents in Taskade can be equipped with "knowledge," which is an aggregate of its training data and the things you teach them. They can also have a unique personality and set of skills that determine what tasks they perform and how they respond to questions.
Alright, enough theory. Let's build one. 👇
### Start with a Template
When it comes to building agents, there's the fully custom way --- think assembling IKEA furniture --- and there's the quick, streamlined method using AI agent templates built into Taskade.
For the purpose of this article, we're going to use the three agent templates to show you around.
💡 If you don't have a Taskade account, create one [here](https://www.taskade.com/signup) for free.
First, go to your [workspace](https://help.taskade.com/en/articles/8958483-create-a-workspace), and navigate to the Agents Tab at the top. This dashboard aggregates all agents within a workspace and allows you to interact with and customize them at any time.
Once inside, click the ➕ Create agent button.
You're now in the AI Agent Builder. We'll spend some time here, so make yourself comfortable.
Taskade features dozens of agent templates you can choose from. That includes specialized agents for project management, design, content creation, and research, just to name a few.
For now, let's select the ✍️ Copywriter agent and hit Create Agent.
Once you've chosen a template, a new window will appear. This is where we'll customize the agent's knowledge, personality, behavior, and commands. We'll discuss all that in the next step.
Before you move on, repeat the process and create two more agents:
- 🔎 Researcher
- 🍎 Brand Strategist
### Train Your Agents
Our ✍️ Copywriter agent comes with general knowledge about a variety of topics. Let's head to the 📓 Knowledge tab and give it a unique voice and expertise.
Hover the cursor over the agent, click the three dots --- on the right, and choose ✏️ Edit agent.
The first step is to get the agent acquainted with our brand's lingo.
We'll use a combination of successful blog articles, archival newsletters, and a set of style guidelines as a foundation. This will allow the agent to learn the patterns behind our brand's tone and style.
💡 Drop the documents into the 📓 Knowledge tab or provide links to sources.
As you can see, the agent has processed the information.
Our AI team is ready to roll; it's time to put it to work. 👇
💡 Agent feature unique [/AI commands](https://help.taskade.com/en/articles/8958457-custom-ai-agents#h_7520226d9e). Visit our [AI prompt guide](https://www.taskade.com/blog/ai-prompting/) to master the basics.
### Deploy the Agents
First, let's create a new project where we'll interact with the agents.
Go to the workspace where your agents are, click ➕ New Project, and choose Start Blank.
Let's say you want to write a newsletter announcing a new update for the app you're working on.
All you have to do is: 1) paste the changelog into the new project, 2) open the Chat (bottom-right), 3) use the selector at the top to choose the ✍️ Copywriter agent, and 4) tell the agent what you need.
The agent can read the project contents so it has all the information it needs to get started.
And here's the result.
In a separate project, we will ask the 🍎 Brand Strategist agent to identify key selling points, align them with our brand message, and brainstorm creative concepts for a multichannel marketing push.
We will also ask the 🔎 Researcher agent to scout market trends and user feedback.
💡 Taskade lets you build [multi-agent systems](https://www.taskade.com/blog/multi-agent-systems/) and run them concurrently within projects. The "pills" under each task indicate which agent is assigned and if the task is in progress.
### (Bonus Point) Put Your Agents on Autopilot
Taskade packs one more secret ingredient that makes agents even more powerful.
With the [Automation Flows](https://help.taskade.com/en/articles/8958467-getting-started-with-automation), you can add your agents into multi-level automated workflows based on triggers & actions that follow a simple "if this then that" logic.
Let's create an automation that will allow the ✍️ Copywriter agent to not only draft all new changelogs into newsletters but also convert them into a blog post inside WordPress.
In your workspace, go to the Automations tab at the top and click ➕ Add automation.
In the pop-up window, choose Start from scratch to create a new automation flow.
Inside the Automation Builder, we're going to choose the New Comment trigger that will activate every time somebody posts a new changelog as a project comment.
Finally, let's add two actions, one that will use the ✍️ Copywriter agent to convert the comment contents into a newsletter, and another that will transfer the draft to a WordPress account.
Now, whenever a new changelog comment is added to a project, the ✍️ Copywriter agent will draft a newsletter in your brand's unique voice and prep a blog post version in WordPress.
Automation opens up a world of possibilities and lets you connect your Taskade account to popular apps and services like Slack, Gmail, Google Forms, Calendly, and many more.

⚡️ Benefits of AI Agent Builders
--------------------------------
So, why use agents, and how are they better than chat-based generative AI tools?
One of the reasons why AI agents are gaining traction is how inefficient interactions with AI are.
Even something as simple as prompting AI to generate newsletter ideas means you need to: 1) provide background information on your product, company, and audience, 2) define the style and tone you're aiming at, 3) provide input information and additional context, and 4) repeat steps 1-3 ad nauseam.
With agents, you only need to do the "training" part once. Once your agents have learned the patterns and picked up the context, they will serve you within your established workflow.
The fact that most chat-based AI tools these days work in a vacuum doesn't help either.
If you already have a solid workflow --- say, you're a digital marketer with a finely tuned content strategy --- AI may help you conduct SEO research, generate a list of topics, or flesh out ideas.
What it won't be able to do is pass the output to the tools you're using.
A custom AI agent with [retrieval-augmented generation (RAG)](https://www.taskade.com/blog/what-is-retrieval-augmented-generation/) can do all that and more.
An integrated agentic workflow allows AI to "talk" to your CRM, sync up with your project management software, "listen" to your email marketing tools, and connect the dots in one place.
Agents can work next to you like team members. They can have unique personalities, skills, and expertise. They won't join you for a cup of morning coffee, but they will have your back 24/7.
🚀 Current Trends and Future Outlook
------------------------------------
AI tools have made remarkable progress since the days of GPT-2 and GP-3.
But where do we go from here? What's the next step in this evolution?
Google Brain co-founder and former chief AI scientist at Baidu Andrew Ng believes that agent-based workflows, as opposed to prompt-based AI interactions, are the future of the AI space.
> "I think AI agentic workflows will drive massive AI progress this year --- perhaps even more than the next generation of foundation models. This is an important trend, and I urge everyone who works in AI to pay attention to it."
We're also likely to see tighter integrations with existing platforms, either through no-code AI agent builders or APIs that will allow developers to embed agents into apps and services.
A team of agents may soon work in seamless collaboration with humans --- monitor progress against milestones, dynamically adjust project parameters in response to roadblocks, and even schedule meetings based on team members' work patterns, all fully autonomously.
The holistic approach seems to be the most natural direction for agents' development. And big tech players like Meta's Mark Zuckerberg already laud an integration of agents with business platforms.
> "I expect that a lot of interest in AI agents for business messaging and customer support will come once we nail that experience. Over time, this will extend to our work on the metaverse, too, where people will much more easily be able to create avatars, objects, worlds, and code to tie all of them together."
Another interesting avenue are physical products like the Humane Ai Pin and Rabbit's R1. AI wearables are still a proof-of-concept, but they may help explore more efficient ways of interacting with agents.
With more advanced large language models around the corner --- OpenAI has already announced a successor to GPT-4 coming later this year --- we're entering a completely new era where agents become deeply integrated, highly intuitive, and essential in our digital and physical lives.
🤔 Challenges and Ethical Considerations
----------------------------------------
Any discussion around artificial intelligence leads to inevitable questions.
How difficult is it to implement? What's the cost? What are the implications?
The cost of investment in custom AI models can be steep. We're talking about potential costs in the range of hundreds of thousands of dollars. That's a tough pill for most businesses to swallow.
AI agent builders that can seamlessly plug into existing apps & services offer a more accessible path. They make deploying and training AI agents quick, painless, and affordable.
For instance, a small retailer could use a customer service agent to handle inquiries, something that was previously only in the realm of e-commerce giants. A local clinic may employ the same agent to manage patient appointments and follow-ups --- routine tasks that eat up valuable time.
Of course, there are other considerations.
Some worry that AI that's too human-like may blur the lines between man and machine. And that in itself comes with a whole lot of interesting conundrums we haven't faced before.
Can agent interactions be clearly distinguished from human interactions?
How can we prevent AI from inheriting and perpetuating human biases?
Who is accountable for the actions and decisions of AI agents?
Building safe agentic systems will be a priority in the coming years. We're likely to see more regulatory bodies and standards that will address these questions. Companies will also need to work closely with legislators, ethicists, and the public to ensure that AI is developed responsibly.
🚀 Wrapping Up: Key Takeaways on AI Agent Builders and Their Impact
-------------------------------------------------------------------
Agentic systems and AI agent builders bring a new quality to the landscape of smart tools. They open up possibilities for more dynamic, contextual, and personalized interactions, without the hefty cost of implementing and training tailored, commercial-grade AI systems.
Whether you're a freelancer, an SMB owner, or just need an extra pair of hands to streamline your workflow, AI agent builders offer an accessible solution with a minimal learning curve.
Before you go, here are a few takeaways from this guide:

1,885,431 | Getting Started: Your Ruby On Rails App Hosted On DigitalOcean With AppSignal | Imagine this: you’ve just finished working on your brand new Rails app and have deployed it to a... | 27,700 | 2024-06-12T08:45:16 | https://blog.appsignal.com/2024/05/29/getting-started-your-ruby-on-rails-app-hosted-on-digitalocean-with-appsignal.html | ruby, rails | Imagine this: you’ve just finished working on your brand new Rails app and have deployed it to a cloud provider like DigitalOcean. Like any developer, you’re very proud of your work but you still have lots of questions, like:
- How well your new app will handle traffic
- Whether the optimizations you put in place will actually work, etc.
Your goal is to provide the best user experience. You want to be notified whenever errors or other important events occur so you can take care of them fast.
It would be great to have a setup that automatically monitors your application. Enter AppSignal! In this article, the first part of a two-part series, we'll set AppSignal up so that you can effectively monitor your Rails app hosted on DigitalOcean.
## Prerequisites
To follow along, make sure you have:
- A local installation of Ruby (this tutorial uses version 3.3.0).
- A local PostgreSQL installation (you can use a Docker version or a locally installed version).
- A [DigitalOcean account](https://cloud.digitalocean.com/registrations/new) to deploy the application.
- An [AppSignal account](https://appsignal.com/users/sign_up) (a free 30-day trial is available).
## An Introduction To Our Ruby On Rails App
For this tutorial, we'll be using a simple Rails 7 expense tracker app. Users will be able to sign up and create entries for their personal expenses, to track their expenses over time.
We'll deploy this app to DigitalOcean, then configure AppSignal's monitoring solution to keep track of what is going on under the hood.
[You can grab the source code or fork the app from here](https://github.com/iamaestimo/expense-tracker) to follow along.
## Deploying Your Rails App To DigitalOcean
We'll use DigitalOcean's app platform to deploy our application. The steps below assume that you've already forked the expense tracker app described above and that you have a DigitalOcean account ready to go.
After logging in, we'll create an app and get it up and running. Since we want to control some parts of this process, though, the first step is to create a database for the app.
### Creating the App Database
Click on the _Databases_ link on the left-hand menu, then click on the _Create Database_ link to create a new PostgreSQL database:
After completing the database settings in the next screen, take note of the database connection string. You'll use it as an environment variable when creating the app in the next step:
_At this point, you'll likely get a warning that your database is open to all incoming connections. Follow the accompanying link to take care of this security warning._
### Creating and Deploying the App
Finally, create the app by first clicking on the _Apps_ link on the left side menu:
Then connect the app's code repository resource as shown below:
Continue to the environment variables screen and insert the copied database URL string. Also, add the `RAILS_MASTER_KEY` as an environment variable since it will be used in the deployment process.
Then, with these environment variables in place, click on the _Next_ button to deploy the app:
With the app successfully deployed, we'll now set up monitoring using AppSignal.
## Setting up AppSignal to Monitor Your Rails App
First, log in to your [AppSignal account](https://appsignal.com/users/sign_in) and choose 'Ruby & Rails'.
Now add the [AppSignal gem](https://github.com/appsignal/appsignal-ruby) to the Rails app. This nifty gem will collect errors, exceptions, and relevant performance data, and port it over to AppSignal for analysis.
Open up the app's Gemfile and add the gem:
```ruby
# Gemfile
gem "appsignal"
```
Then run `bundle install`.
Finally, you'll need to run the installation script that comes with your account-specific API key attached. When you run this install script, you should get something similar to the below:
```shell
bundle exec appsignal install <redacted>
#######################################
## Starting AppSignal Installer ##
## --------------------------------- ##
## Need help? support@appsignal.com ##
## Docs? docs.appsignal.com ##
#######################################

Writing config file...
Config file written to config/appsignal.yml
#####################################
## AppSignal installation complete ##
#####################################
Sending example data to AppSignal...
Example data sent!
```
There are a couple of things to note when you run the script:
- You'll get the option to change your app's name as it will appear on AppSignal's dashboard or leave the default option.
- You'll also get the option to choose how you want AppSignal configured for your app. In my case, I went with the config file option, creating a config file in `config/appsignal.yml`, with the below content:
```yaml
# config/appsignal.yml
default: &defaults
push_api_key: "<%= ENV['APPSIGNAL_PUSH_API_KEY'] %>"
name: "ExpenseTracker"
development:
<<: *defaults
active: true
production:
<<: *defaults
active: true
```
Here, we define:
- A `push_api_key` which connects the app to AppSignal.
- The app's name as it will appear on AppSignal.
- The environments in which AppSignal will monitor the app (in this case, both development and production environments).
By the way, if you'd like to turn off AppSignal monitoring on the development environment, just set the `active` flag to `false`, like so:
```yaml
...
development:
<<: *defaults
active: false
...
```
_**Tip**: Both the config file and environment variable options do the same thing. They define how AppSignal will connect to your app, the app name, and which environment will be monitored._
Assuming everything goes to plan, you should see a screen showing that AppSignal is receiving data from your app!
## An Introduction to AppSignal's Dashboard for Rails
Now that everything is set up correctly and AppSignal is receiving data from your app, you can access the default app monitoring dashboard view as shown below:
_**Tip**: If you set up monitoring for both development and production environments, you can easily switch between them from the selection shown by the arrow._
From the default view, you have access to the following default charts:
- **Error rate** - This will show the rate of errors occurring in your app per unit of time.
- **Throughput** - Here, you'll get a snapshot of the throughput your app is able to handle in terms of requests per minute.
- **Response time** - This will show your app's response times.
- **Latest open errors** - This section will list the latest errors that will have happened within your app.
- **Latest open performance measurements** - This section lists the latest performance measurements, including method calls, API requests, etc.
Next, we'll see how to set up proper error tracking for a Rails application using AppSignal.
## Monitoring Errors with AppSignal
There are more than ten error types that could affect a running Ruby on Rails app. Obviously, some are more common than others. In this section, we'll simulate a few of these errors and see how AppSignal handles them. Let's start with a simple example first.
Since the expense tracker app is using Devise for authentication, let's add a check for whether a user is signed in. Instead of using the recommended `user_signed_in?` method, let's use the erroneous `user_logged_in?` method, which should trigger an `ActionView::Template::Error`:
```erb
<!-- app/views/shared/_navbar.html.erb -->
...
<% if user_logged_in? %>
<%= link_to 'Logout', destroy_user_session_path %>
<% else %>
<%= link_to new_user_session_path do %>
Login
<% end %>
<% end %>
...
```
Deploy this change, reload the production app, then go into the production environment dashboard in AppSignal and watch how this error shows up:
AppSignal makes it a breeze to get more details on any errors that happen in an application. For example, we can get details about the _ActionView_ template error by clicking on it from the 'Latest Open Errors' dashboard panel.
You can clearly see that the error is caused by an undefined method which points us in the right direction to fix it.
AppSignal's Errors dashboard also gives you extra information through the _Logbook_ and _Settings_ panels:
- **Logbook** - Here, you or your team members can add comments to an error being tracked by AppSignal. The Logbook panel also shows a chronological breakdown of any actions taken regarding the error in question.
- **Settings** - From this panel, you can assign an error to another team member, change alert settings (we'll check these out in detail in the second part of this tutorial), and set error severity.
And that's it for this part of the series!
## Wrapping Up
In this tutorial, we deployed a simple Rails application to DigitalOcean's app platform and hooked it up to AppSignal's application monitoring platform. We also went through how errors are monitored and displayed in AppSignal's Errors dashboard.
Obviously, this is just scratching the surface of what's possible with AppSignal. In the second part of this series, we'll dive deeper into performance measurements, anomaly detection, uptime monitoring, and logging.
In the meantime, happy coding!

1,885,425 | Access Tokens vs Refresh Tokens vs ID Tokens | In modern web and mobile applications, securing communication between clients and servers is... | 0 | 2024-06-12T08:39:48 | https://dev.to/rahulvijayvergiya/access-tokens-vs-refresh-tokens-vs-id-tokens-3c97 | tokens, jwt, idtoken, refreshtoken | In modern web and mobile applications, securing communication between clients and servers is critical. Tokens play a significant role in this process, especially in authentication and authorisation mechanisms. Among these tokens, Access Tokens, Refresh Tokens, and ID Tokens are the most commonly used. This article explores their differences, purposes, and how they work together to provide secure and efficient access control.
## 1. Access Tokens
### Purpose:
Access Tokens are primarily used to authorise access to protected resources or APIs. When a user logs into an application, the application requests an Access Token from an authorisation server (like OAuth 2.0). This token is then used to access resources on behalf of the user.
### Characteristics:
- **Short-lived:** Access Tokens typically have a short lifespan, usually ranging from a few minutes to a few hours. This minimises the risk of misuse if the token is compromised.
- **Bearer Token:** They are usually bearer tokens, meaning that any party in possession of the token can use it to access the associated resources.
- **Stateless:** Access Tokens are generally stateless, meaning the server does not need to store token details; instead, it validates the token based on its signature and claims.
### Usage:
When an application needs to access protected resources, it includes the Access Token in the HTTP Authorisation header as a Bearer token:
```
GET /resource HTTP/1.1
Host: api.example.com
Authorization: Bearer <access_token>
```
## 2. Refresh Tokens
### Purpose:
Refresh Tokens are used to obtain a new Access Token without requiring the user to re-authenticate. This is particularly useful for maintaining a seamless user experience in applications where users need continuous access over extended periods.
### Characteristics:
- **Long-lived:** Refresh Tokens typically have a longer lifespan compared to Access Tokens, often lasting days, weeks, or even months.
- **Secure Storage:** They must be stored securely (e.g., using encrypted storage) because their long lifespan increases the risk if they are compromised.
- **Revocable:** The server can revoke Refresh Tokens at any time, for instance, if a user logs out or if there are security concerns.
### Usage:
When an Access Token expires, the application sends the Refresh Token to the authorisation server to obtain a new Access Token:
```
POST /token HTTP/1.1
Host: auth.example.com
Content-Type: application/x-www-form-urlencoded
grant_type=refresh_token&refresh_token=<refresh_token>
```
## 3. ID Tokens
### Purpose:
ID Tokens are used to authenticate the user and provide identity information. They are commonly used in OpenID Connect (OIDC), which is an identity layer built on top of OAuth 2.0.
### Characteristics:
- **JWT Format:** ID Tokens are typically JSON Web Tokens (JWT), which are compact and URL-safe, making them easy to pass around in web applications.
- **Claims:** They contain claims about the user, such as user ID, name, email, and other profile information.
- **Short-lived:** Like Access Tokens, ID Tokens also have a short lifespan to reduce security risks.
### Usage:
When a user logs in, the authorisation server issues an ID Token along with the Access Token. The ID Token can be used by the client to get user information without querying the user database:
```
{
"iss": "https://auth.example.com",
"sub": "1234567890",
"aud": "client_id",
"exp": 1311281970,
"iat": 1311280970,
"name": "John Doe",
"email": "john.doe@example.com"
}
```
## Differences and How They Work Together
### Access Tokens vs. Refresh Tokens:
- Access Tokens are used for resource access and are short-lived to minimise security risks.
- Refresh Tokens are used to obtain new Access Tokens without user re-authentication, providing a balance between security and user experience.
### ID Tokens vs. Access Tokens:
- ID Tokens are for authentication and carry user identity information.
- Access Tokens are for authorisation and grant access to resources.
## Practical Workflow:
1. **Authentication:** The user logs in, and the authorisation server issues an ID Token and an Access Token.
2. **Resource Access:** The application uses the Access Token to access protected resources.
3. **Token Refresh:** When the Access Token expires, the application uses the Refresh Token to get a new Access Token.

1,885,422 | Pros and Cons of Benchmark Testing | Benchmark testing serves as a crucial process for evaluating the performance and capabilities of... | 0 | 2024-06-12T08:35:39 | https://dev.to/ngocninh123/pros-and-cons-of-benchmark-testing-2ki3 | benchmarktesting, testing | Benchmark testing serves as a crucial process for evaluating the performance and capabilities of various software systems, hardware components, and applications. By simulating real-world usage patterns and comparing results against predefined standards or benchmarks, developers and IT professionals gain valuable insights into the efficiency and reliability of their [test software](https://www.hdwebsoft.com/software-testing-services).
However, like any testing methodology, benchmark testing has its own set of advantages and disadvantages. Understanding these pros and cons can empower organizations to make informed decisions about integrating benchmark testing into their software development and maintenance processes. This blog will delve deeper into the specifics of both sides of the coin, helping you determine if benchmark testing is the right fit for your software development needs.
## Pros of Benchmark Testing
Ensuring your software performs flawlessly for every user is crucial, but how do you know where to begin improvements? Benchmark testing sets a baseline for your software's performance, providing a valuable starting point for optimization. Let's take a look at how it works to your advantage:
**Improved Performance Insight**
Benchmark testing goes beyond basic functionality checks, offering a deep dive into an application's performance under simulated load. This detailed analysis helps developers pinpoint bottlenecks and areas for optimization.
A study by researchers at Netflix found that by implementing A/B testing and data-driven performance analysis, they achieved a [10%](https://netflixtechblog.com/tagged/performance) reduction in content delivery costs while maintaining a high-quality user experience. By identifying inefficiencies and focusing optimization efforts on these areas, benchmark testing empowers developers to make targeted improvements that can significantly enhance overall application efficiency and, as the Netflix study suggests, even lead to cost savings.
**Enhanced User Experience**
Benchmark testing goes beyond technical jargon and dives straight into user experience. Studies by Google show a whopping [70% drop](https://www.thinkwithgoogle.com/marketing-strategies/app-and-mobile/mobile-page-speed-data/) in conversion rates on landing pages with just a 1-second mobile load time delay.
Benchmark testing helps identify these performance bottlenecks before they frustrate users. By simulating real-world usage patterns and analyzing metrics, it ensures your app delivers a fast and responsive experience. This translates to happy users who keep coming back for more, ultimately boosting engagement and conversion rates.
**Competitive Advantage**
Benchmark testing isn't just about internal optimization; it's a strategic tool for market positioning. By comparing performance against industry standards and competitor products, especially for e-commerce platforms, companies gain valuable insights. This allows them to identify areas where their systems excel, showcase strengths in marketing materials, and highlight a competitive edge.
Conversely, benchmark testing reveals potential weaknesses compared to competitors. This empowers companies to prioritize performance improvements, ensuring their products stay competitive and meet evolving user expectations in the market.
## Cons of Benchmark Testing
Benchmark testing provides a valuable snapshot of software performance, but all aspects must be considered to ensure the results accurately reflect real-world scenarios. Here's a breakdown of key factors to keep in mind when designing and interpreting benchmark tests:
**Resource Intensive**
While benchmark testing offers undeniable advantages, it's not without its challenges. The process can be resource-intensive, requiring significant investment in time, effort, and potentially specialized tools. This can be a hurdle for smaller teams or organizations with limited budgets.
A study by Tricentis highlights this challenge, reporting that [37%](https://www.scrum.org/resources/blog/why-teams-adopted-scrum-during-pandemic) of software development teams struggle to allocate sufficient resources for performance testing. This emphasizes the importance of careful planning and prioritizing testing efforts to maximize the value of benchmark testing within resource constraints.
**Complexity in Setup**
One of the hurdles in benchmark testing lies in creating and maintaining realistic testing environments. Accurately mimicking real-world user behavior and system load is a significant challenge. Factors like user location, device variations, and network fluctuations all contribute to a dynamic user experience. Recreating this complexity in a controlled environment requires meticulous planning and configuration.
Furthermore, maintaining consistency across multiple test runs is crucial for reliable data analysis. Any deviations can introduce errors and invalidate results. This interplay of complexity and meticulousness can lead to extended setup times and the potential for inaccuracies in the final benchmark results.
**Dependency on Test Conditions**
Performance testing is a powerful tool, but its effectiveness hinges on reliable results. A critical factor influencing this reliability is consistency within the test environment. Factors like hardware configurations, network bandwidth, and operating systems can all significantly impact performance metrics.
Unfortunately, ensuring a perfectly uniform test environment can be challenging. Differences in development, staging, and production environments are inevitable. To address this, meticulous planning and configuration management are crucial. By meticulously replicating real-world conditions as closely as possible, performance testing can deliver accurate and actionable insights, ultimately leading to a more optimized and responsive application.

부트캠프나 국비지원, 독학 등 개발자가 되기 위한 또는 시작하기 위한 방법들은 다양하다.
수많은 기관과 각 종 채용 연계 프로그램을 통해 개발자가 넘쳐나기 시작하였다. 연달아 코로나가 터지고 비대면이 증가하면서 개발자에 대한 수요는 기하급수적으로 올라갔다. 말 그대로 개발자 호황기다.
그러다 **2022년 이후 개발자 시장은 완전히 바뀌었다.**
이전 개발자 붐으로 인해 수 많은 개발자들이 시장에 넘쳐 나고, 금리 상승 및 스타트업 투자 급감 등으로 인해 개발자 채용 시장은 인력 감축하고 생존 모드에 들어섰다.
이후 많은 신입 개발자들은 높은 채용 요구사항과 더불어 3년 이상 경력자들과 경쟁하여 채용 바늘 구멍을 통과해야 하는 현실로 바뀌었다.
그런 현실을 반영하여 경쟁에서 뒤쳐지지 않기 위해 필자는 항해99 취업 리부트 코스를 지원하였다.
## 코스 선택 이유
결론부터 말하자면 취업 지원에 진심이다.
그리고 현재 시장을 누구보다 잘 알고 도움을 주기 때문에 지원하게 되었다.
더군다나, 다른 개발자 분들과 네트워킹을 통한 환경이 구축되어 있기 때문에 많은 도움을 받고 의지할 수 있기 때문이기도 하다.
정리하자면 장점은 다음과 같다.
> - 취업 지원을 아낌없이 해준다.
> - 온라인으로 진행되어도 네트워킹 참여도가 활발하다.
> - 이력서, 코딩테스트, 프로젝트, 면접 등 취업 전반에 필요한 항목을 점검하고 보완할 수 있다.
> - 수료 이후에도 이력서 및 면접 코칭이 가능하다.
> - 멘토링 시스템을 통해 원하는 질문에 대한 답변을 얻을 수 있다.
> - 발등에 불 떨어질 일은 없다.
이 중에서 현재 불안한 시장에서 부족한 `이력서와 면접 실력`을 지속적으로 피드백 해주고 지속적으로 고쳐나갈 수 있다는 장점이 이 취업 리부트 코스만의 가장 큰 장점이라 생각한다.
## 코스 이후
필자가 가장 만족하는 부분은 `이력서`와 `코테` 부분이다.
이력서 작성방법, 코딩테스트 대비 방법 등 무엇이든 방법을 알고 그 방법을 잘 적용하여 내 것으로 만든다면 많은 시간과 노력 대비 효과적인 결과를 만들어 낼 수 있는 것 같다.
현재 이력서와 이전 이력서를 비교하면 어떻게 이전 이력서를 가지고 취업지원을 하였는지 부끄럽다.
코딩테스트 역시 방법을 알고 시작하니 앞으로 어떻게 코테에 대비해야 하는지, 부족한 부분은 어떻게 매꿀 수 있는지 방향성을 알게 되었다.
면접 실력 향상에는 왕도가 없다. 꾸준히 지원하고 실전 경험을 쌓는 것이 중요하다고 생각한다. 그리고 지속적인 지원을 받을 수 있어서 면접에 대한 부담을 조금은 덜게 되었다.
> 필자는 항해에서 코딩테스트 문제를 풀고 [백준 플래티넘](https://solved.ac/profile/fkdlxmfkdl1)을 달성하였다.
## 마지막 한마디
무엇이든지 시작하고 있다면 좋은 징조라 생각한다.
아무것도 하지 않는 것 보다 지금 내게 가장 필요한 것을 찾고 그것을 바로 시작하면 된다.
필자 역시 이 코스를 수료하고 나서 앞으로 필요한 것들이 많이 생겨났다.
> - 오픈소스 기여하기
> - 코딩테스트 필수 유형 정복하기
> - 맛집 블로그 키우기
> - 개발자 커뮤니티 활성화하기
> - 좋은 프로젝트 코드(가독성, 추상화 등)에 대한 POC
> - 사용자 100명 이상 운영되는 서비스 배포해보기
이전과 비교하여 취업 시장에서 유리해진 점은 확실하다.
모든지 자기 하기 나름이다.

1,885,412 | Critical Rendering Path (CRP) | Understanding Critical Rendering Path is crucial in web development, as it impacts performance and... | 0 | 2024-06-12T08:29:42 | https://dev.to/nazarhapak/critical-rendering-path-crp-optimization-techniques-2kbd | webdev, performance, javascript, html | Understanding Critical Rendering Path is crucial in web development, as it impacts performance and user experience of website. As a web developer you can optimize Critical Rendering Path for better perfomance and SEO rankings.
In this article, we will look at basic terms of Critical Rendering Path, its sequence and techniques to optimize it.
## What exactly is CRP? 🤔
**Critical Rendering Path (CRP)** is a sequence of steps that the browser takes to convert HTML, CSS and JavaScript into pixels on the screen.
## Understanding Terms 🧠
- **Parsing** is a process of converting HTML and CSS into structures that the browser can understand and manipulate.
- **Rendering** is a process of converting DOM and CSSOM into pixels on the screen.
- **DOM (Document Object Model)** is a tree-like structure representing the HTML content of a web page. Each element, attribute, and piece of text in the HTML document becomes a **node** in this tree.
- **CSSOM (CSS Object Model)** is a tree-like structure that represents the CSS styles of a web page.
- **Render Tree** is combination of DOM and CSSOM. It contains only the nodes needed to render the page, including the visual information like styles and layout.
## Sequence in CRP 🚦
Steps in rendering process:
1. As browser receives **first package** of _HTML file_, it starts constructing the DOM.
2. It continues the process of DOM construction and as soon as browser discovers a reference to CSS file (`<link rel="stylesheet">`) it sends HTTP request for CSS file.
3. When it receives packages of _CSS file_, it starts **simultaneously** constructing the CSSOM.
4. When the browser counters reference to _JavaScript file_ (`<script>` element) it **stops parsing** HTML and CSS, as JavaScript can directly manipulate DOM and CSSOM. Only after JavaScript finished downloading and executing, parsing process continues.
5. When browser encounters tags for external data like _images, videos, audio etc_, it notes the locations of files but continues parsing the rest of the page. The browser can perform the initial paint of webpage even if the external data hasn't been fully loaded yet. (That's why u can see how images load even after main content has already appeared on screen).
6. DOM and CSSOM are combined to form the Render Tree, which represents what will be displayed on screen.
7. The browser makes the layout. It calculates the exact position and size of each visible element.
8. The browser paints pixels on the screen and displays the webpage.
Note, that when content on a webpage changes dynamically (text changes color, hover animations etc) or additional content is loaded browser **do not repaint the entire page**, instead it selectively updates parts of the page.
## CRP Optimization Techniques 💪
### Minimize Critical Resources
- Ensure only the necessary resources are included in the critical path.
- Use minification tools (to remove blank space) and compression(.zip) to reduce the size of resources.
### Optimize CSS Delivery
Even though CSS simultaniously parsing itself along with HTML, rendering process won't start until both DOM and CSSOM are ready. So, it is a good idea to render important CSS first and defer everything else.
- Inline important CSS content directly in the HTML.
- Load non-critical CSS asynchronously. `<link rel="stylesheet" href="style.css" media="print" onload="this.media='all'">`
### Optimize JavaScript Delivery
As you know for now, JavaScript blocks the parsing process of HTML and CSS as it can directly manipulate DOM and CSSOM.
By default JavaScript behaviour, it stops parsing while it downloads and executes. But you can use `defer` and `async` attributes to change that.
- Defering JavaScript ownloads it while HTML is parsing and executes it after it's done constructing DOM. `<script src="script.js" defer></script>`
- Downloading JavaScript asynchronously happens while HTML is parsing, but execution happens as soon as JavaScript file has finished downloading. `<script src="example.js" async></script>`
Many developers also put their scripts at the end of `<body>` element to ensure that they are loaded after HTML has been parsed.
You can also inline important JavaScript directly in HTML just like CSS.
### Use Preloading and Prefetching
- Preloading tells the browser to start fetching the file as soon as possible, before it is discovered in the document’s standard flow. This means the file is given a high priority. It doesn’t block the rendering process. `<link rel="preload" href="styles.css" as="style">`
- Prefetching loads resources that might be needed in the near future. By fetching them in advance, browser can serve them from cache when they are actually needed. These files are given lower priority, which means that they are loaded after everything else. `<link rel="prefetch" href="about-us.html">`
##Summary 📝
Critical Rendering Path is a sequence of steps which browser takes to display web content and there are several techniques to optimize it.

1,885,416 | How to Download Netflix Movies on MacBook for Offline Viewing | In this guide, we will explore how to download Netflix movies on your MacBook for offline viewing.... | 27,699 | 2024-06-12T08:29:39 | https://dev.to/nancychiu_/download-netflix-movies-on-mac | netflix, software | In this guide, we will explore how to download Netflix movies on your MacBook for offline viewing. Whether you're planning a long trip or just want to watch your favorite movies without worrying about internet connectivity, downloading Netflix movies on your MacBook can be incredibly useful.
Being able to download Netflix movies allows you to watch them anytime, anywhere, even without an internet connection. This is especially beneficial during travel, in areas with poor Wi-Fi, or when you simply want to save on data usage. Let's dive into the various methods you can use to download Netflix movies on MacBook.
## Using Netflix App Download Netflix Movies on MacBook
For downloading Netflix movies on your MacBook, the most reliable method is using the official Netflix app. This approach offers simplicity, security, and seamless integration with your device. Through the Netflix app, users can effortlessly access a wide range of content for offline viewing, ensuring a convenient and enjoyable entertainment experience. Let's explore this official method in detail.
### Before Using Netflix App You Must Know: Netflix Download Limit on MacBook
When it comes to downloading TV shows and movies from Netflix for offline viewing, MacBook users encounter a limitation: **the official Netflix app does not support downloads on MacBook devices**. Unlike other supported devices such as Android phones, iPhones, Windows computers, Amazon Fire tablets, and Google Chromebooks, MacBook users are unable to directly download content from the Netflix app.
**To access the download feature, users must utilize one of the supported devices listed below:**
- Android phone or tablet
- iPhone or iPad
- Windows 10 or Windows 11 computer
- Amazon Fire tablet
- Google Chromebook (with Google Play Store installed)
While installing the Netflix app directly on MacBook or iMac devices may not be feasible, there are alternative methods available:
- For MacBook Air/Pro/iMac with Apple Silicon (M1/M2/M3 chips), consider using the Netflix iOS App.
- If you're using a MacBook Air/Pro/iMac with Intel chips, try accessing Netflix through the Windows App.
### Method 1: Using the Netflix iOS App with Apple Silicon
As commonly understood, **Apple Silicon Mac** are capable of running iOS apps, yet Netflix has officially prohibited this functionality. To circumvent this limitation and download Netflix movies on your MacBook, you can employ **iMazing** to export the Netflix app from your iPhone or iPad.
**Follow these steps:**
1. Make sure you have an iPhone or iPad running iOS 14.01 or later with the Netflix app already downloaded.
2. Download and launch iMazing on your MacBook.
3. Connect your iOS device to your Mac using a USB cable.
4. Navigate to "Apps" > "Manage Apps" > "Library" within iMazing to access all downloaded apps on your iOS device.
5. Locate the "Netflix" app, double-click on it, and select "Export .IPA".
6. Run the "IPA" file to install the iOS Netflix app on your Mac, then proceed to launch the Netflix app.
7. Sign in to your account, and you'll be able to download Netflix movies on your MacBook for offline viewing.
### Method 2: Using Parallels for Windows Virtual Platform
Another popular method for downloading Netflix movies on MacBook involves setting up a Windows virtual platform using Parallels. This allows you to utilize the official Netflix app for direct downloads. While this method is secure, as it uses the official app within a virtual Windows environment, it does come with some limitations. The process can be complex, with cumbersome procedures, and it demands high computer performance, potentially leading to system lag. Additionally, it only offers access to a one-year paid package.
While this method ensures security, its complexity and resource-intensive nature may not be suitable for all users looking to download Netflix movies on their MacBook.
## Alternative Method: Easier and Faster - MovPilot Netflix Video Downloader
Using a dedicated Netflix video downloader is the best alternative method to download Netflix movies on MacBook. **MovPilot Netflix Video Downloader**, designed specifically for Netflix on Mac. With macOS X 10.11 or later, you can easily download any Netflix video on both MacBook and iMac using any Netflix plan.

We all love good, simple lists to tick off tasks. But if you're in the project management business, you need something better. Gantt charts are an excellent tool for mapping projects' life cycles, with a clear overview of start and end dates, who's doing what, and how it all overlaps. Here's it works.
💡 Learning the ropes? Read our guide on the [basics of project management](https://www.taskade.com/blog/project-management-basics/) first.
📐 What Is a Gantt Chart?
-------------------------
To answer this question, we need to move to 19th century Poland.
In the early 1890s, a Polish engineer Karol Adamiecki developed a tool called the "harmonogram," which was designed to organize tasks and timelines visually within a project. The harmonogram showed a sequence of tasks and their duration, together with the interdependencies between them.
The Harmonogram designed by K. Adamiecki^(1)^
While Adamiecki's idea was groundbreaking, it didn't get widespread attention beyond Poland and Russia. That happened much later with the work of Henry Gantt in the United States.
Circa 1910, Gantt devised his own version of the chart, which was essentially an improvement of the harmonogram. Gantt's variation presented tasks against time more clearly and was used extensively on major infrastructure projects, for example, the Hoover Dam and the Interstate Highway system.
Source: "Organizing for Work" by H. L. Gantt^(2)^
In their modern iteration, Gantt charts are often integrated into project management software, complete with real-time updates, drag-and-drop workflow, and AI support.
But we'll get to that in a moment.
Now that we know the "what," let's talk about the "how."
🗓️ How Do Gantt Charts Work?
-----------------------------
A typical Gantt chart is a horizontal bar chart that represents tasks within a project schedule. It shows the start and end dates of the various elements of a project. Just like this one:
On the left side of the chart, you'll find a task list.
On the right, you'll see the tasks transform into horizontal bars across a grid --- this is where the scheduling magic happens. Each bar indicates the duration of a corresponding task --- their position and length are your visual cues for the timeline: when a task begins and how long it's expected to last.
At the top of the Gantt Chart, there's a timeline that helps position tasks in time and track project progress, usually on a daily, weekly, monthly, or yearly scale.
In some Gantt charts, you'll also see lines connecting the horizontal bars representing individual tasks. They show task relationships or dependencies --- which tasks need to be finished before others can start.
The workflow is simple.
Every time you start a new project, you list individual tasks on the left. Then, you need to figure out an optimal start and finish date for each task and plot these as bars on your chart. Finally, if things shift, so if a task takes more or less time than expected, you make adjustments to reflect those changes.
So, why are Gantt charts so powerful?
🚀 Benefits of Using Gantt Charts
---------------------------------
### Enhanced Planning and Scheduling
🗓️
Gantt charts provide a bird's-eye view of your project's journey, breaking it down into bite-sized steps. You know when each stage is supposed to happen and how it connects to entire projects.
If you're a visual learner or thrive on structure, there is no better tool for planning ahead.
### Real-Time Progress Tracking
⚡
A Gantt chart is essentially a visual snapshot of a project. This means that it makes it extremely easy to track how fast you're moving and where you are relative to set project deadlines.
Whether you're cruising ahead or falling behind, a quick glance at the chart will tell you the whole story --- your current status, progress achieved, and potential roadblocks --- all in one place.
### Easier Resource Management
🗂️
Resources are like your project's fuel, and you've got to use them wisely.
Gantt charts help you spread out tasks so that your team isn't running on empty. You can see who's doing what and make sure no one's swamped while others are twiddling their thumbs.
By visualizing the workload distribution, you can identify potential resource constraints or bottlenecks and take proactive measures to address them.
### More Accurate Tracking
🔎
Imagine you're publishing a book.
There are editors to consult, covers to design, and pages to print --- that's a lot to handle. A Gantt chart will show you what's coming your way in the short and long-term perspective to make it manageable.
Plus, having deadlines staring back at you keeps the pressure on just the right amount.
🚧 Limitations and Considerations
---------------------------------
### Limited Flexibility
If the most thought-out plans have a tendency to shift, and the rigid structure of Gantt charts means that every time that happens, you're up for some heavy-duty reshuffling to reflect those changes.
Modern project management software with drag-and-drop interfaces makes the process very intuitive. But you still have to figure out how each change affects the overall [project timeline](https://www.taskade.com/wiki/project-management/project-timeline) and dependencies.
### Tendency for Complexity
Too much detail, too many day-to-day fluctuations, and the small tasks that keep the wheels turning can get overwhelming. This is especially true for visual-first project management tools.
Gantt charts are fantastic for tracking major milestones. But as your projects grow in complexity, so does the timeline, which means you'll likely need to make some sacrifices to keep things transparent.
### Limited Forecasting Accuracy
The Gantt chart can tell you and your team how long a task is supposed to take. But it doesn't account for task complexity or how many resources need to be involved.
Some tasks may appear deceptively straightforward on the chart but end up devouring more time and resources than anticipated because of their complexity or unforeseen challenges.
Similarly, certain tasks may require additional resources or expertise that were not initially accounted for in the Gantt chart. And this is a straight way to delays and bottlenecks down the road.
🐑 Creating a Gantt Chart Inside Taskade
----------------------------------------
If you're new to Taskade, here's a tl;dr.
Taskade is a holistic, AI-powered project management platform that's tailored for teams and individuals. Whether you're a project manager, a business owner, or part of a global team, Taskade gives you the flexibility you need to build great products and services anytime, anywhere.

Creating a Gantt chart in Taskade is simple.
Let's walk through the core components and steps really quickly.
### Set Up a New Project
First, you need to create a project inside your workspace.
(psst... read our [hierarchy structure article](https://help.taskade.com/en/articles/8958376-hierarchy-structure) to learn about both).
To do that, click the ➕ New Project button in the top-right corner of the main dashboard. There are several options here, but let's choose Start Blank at the top.
You're now in the project editor.
💡 Note: Taskades stores projects in tree-shaped databases. This means that you can transform them in many different ways. We call this approach [the Origami method](https://help.taskade.com/en/articles/8958384-what-are-project-views#h_72df614ad4).
To save the project and enable the Gantt Chart view:
1. Type a name for your new project
2. Click the Gantt Chart button in the top navigation bar (first icon from the right).
💡 Note: There are [seven unique project views in Taskade](https://help.taskade.com/en/articles/8958384-what-are-project-views) --- List, Board, Table, Mind Map, Org Chart, Calendar, and Gantt Chart. Be sure to try them all!
There is not much happening in our project; we need to add a few details to kick things off.
### Add New Tasks
To add new tasks, click the ➕ New task button and type their titles.
Now, we need to add the new tasks to the timeline on the right.
Find the appropriate start date on the timeline and click an empty space on the same level as your task on the left. You can adjust the duration by dragging the corners of timeline items to extend or shorten it.
⭐ Pro Tip: Swipe with two fingers on your trackpad or "drag" the timeline to find the dates you're looking for. You can also adjust the view using the time scale selector in the top-right.
Here's the final result.
### (Bonus Point) Navigate the Gantt Chart
The Gantt Chart view comes with a handful of useful features.
The vertical line on the chart is the Today Marker. It indicates the current date and provides a clear reference point for evaluating the project's progress against the planned project schedule.
Seeker Arrows --- you will find them at the edges of the timeline --- serve as navigational buttons. They allow you to quickly jump to tasks on the timeline, which is useful in longer projects.
Want to adjust priorities?
Click and hold at the center a task in the timeline and drag it left or right along the timeline.
✨ Practical Applications of Gantt Charts
----------------------------------------
Alright, so what's the best place and time to use Gantt charts?
Well, it depends on the type of industry you're in and the nature of the projects you're dealing with.
Traditionally, Gantt charts have been used in industries like construction, manufacturing, and engineering, where [project roadmaps](https://www.taskade.com/blog/project-roadmap/) and dependencies are organized into clear-cut phases.
But there are other areas where they come in handy.
For example, if you're developing an app, a Gantt chart can also help you break down the development process into bite-sized tasks and keep things under control. Or, if you're in the consulting business, charts can help you communicate with clients in a visual way.
Of course, that's not all.
In marketing and advertising campaigns, you can use charts to align multiple project streams. In event planning, they help coordinate all the moving parts, from venue preparation to vendor management.
Pretty cool, huh? But there is one more piece of the puzzle we need to discuss.
🤖 How Taskade AI Can Interact With And Generate Gantt Charts
-------------------------------------------------------------
This may sound lofty, but artificial intelligence has transformed the project management space for good. And we're not talking about mere data analytics or pattern recognition. That's old news.
We're talking about AI models that can interact with the project management tools you're already using.
Take the Gantt chart we created earlier. At a glance, it's a traditional timeline --- a linear representation of a project life cycle. It looks like a Gantt chart and does the garden-variety Gantt chart things.
But what really sets it apart is a full integration with Taskade AI.
Watch this short video introduction first:
Let's say you want to start a new phase in your project and need to estimate the duration of tasks. All you have to do is select those tasks in the project editor and use the /estimate duration AI command. Taskade AI will crunch the numbers and give you solid estimates for each item in an instant.
💡 Note: The /estimate duration command is part of the ✅ Task custom agent. Read our [guide to learn how to set up your own custom AI agents](https://help.taskade.com/en/articles/8958457-custom-ai-agents).
We can take this a step further.
Remember what we said about granularity? Let's try to break down the chunky tasks on the timeline into smaller, more manageable activities. To do that, type /subtask next to individual items. You can also bulk-select the entire list and apply the same command to all of the items.
The AI Assistant, which is part of Taskade's suite of AI-powered features, can even generate complete Gantt charts for your projects from scratch. All you have to do is describe what you're working on --- think objectives, deadlines, required resources, or available manpower --- and let AI do its magic.
🐑 Wrapping Up: The Strategic Edge of Gantt Charts in Project Management
------------------------------------------------------------------------
Alright, time to wrap this up.
You've learned what Gantt charts are and know how to use them. You also know how to leverage AI to make the most of this simple but mighty project management tool. And that's a good start.
All that's left is practice.
Gaining proficiency with Gantt charts in project management doesn't happen overnight, but as with any skill worth mastering, the payoff is worth the effort. So, dive in and experiment with your own projects. Start small if you need to; use charts to visualize your workflows and tweak as you go.

However, Microsoft took shots at React and announced they are not going to use it for Edge anymore.
After their article, developers questioned whether React is worth learning anymore.
I will explain their entire article and how it affects React, JavaScript Developers, and what are the true intentions of the Microsoft Edge Team.
## History
_Microsoft Edge is built using Chromium_, an Open-Source web browser project by Google. The default UI of Microsoft Edge is derived from Chromium.
Microsoft doesn't want Edge to look like Chrome (obviously). Therefore, Edge has UI components and elements designed by Microsoft. However, these components are made using React.
Many small components throughout Edge are created using React which collectively builds the entire browser.
The entire Edge browser isn't a React application. It combines multiple components in the form of HTML pages with React in them. The menu, dropdown, and the favourites tab are mini React apps.
That's not efficient, right? Especially for UI data that never changes dynamically. **Its inefficiency has caused Microsoft to doubt React**.
_But this story is half-baked_. We'll soon unveil whether React was at fault or Microsoft had a manufactured flaw.

{% embed https://store.afankhan.com/l/codenexus %}
---
## The Problems
Microsoft claims that React isn’t efficient, so they made improvements and announced it in an article published on _May 28th, 2024_.
{% embed https://youtu.be/avJmgfGpoJA %}
Microsoft observed that the bundles of code shared between multiple components were too large and that caused the browser to slow down.
They weren’t supposed to share a bundle with different components, but as they claim it is a problem, here are their reasons:
1. There was a modularity issue with the UI code. **The teams working on different components shared common bundles, files, etc**. It resulted in one part of the UI slowing down another part by sharing things that weren’t necessary.
2. **_Microsoft used a framework that relied on JavaScript to render the UI using the client-side rendering technique_**. Microsoft claims this is the second reason to slow their browser down.
As I explained earlier, Edge shared multiple React applications.
They didn’t initiate multiple React projects but used a single JavaScript Bundle in various places and mounted the Bundle to multiple props in many components.
> A JavaScript Bundle is an optimization technique that combines multiple JavaScript files into a single line to reduce and process the server requests efficiently.
And the second reason is why I am writing this article. Indirectly, Microsoft addressed React as the framework that caused the bundle problem for them.
Microsoft addressed React indirectly because they are working on React-based projects, like React Native for Windows, MacOS, and Xbox. However, they still loathe it for Edge.
**Even though Microsoft is building React Native, they still don’t use it for Edge**. Edge is a native desktop application and React Native would be an ideal solution, but Microsoft begs to differ.
It is because using HTML, CSS, and JavaScript, or React for menus, dropdowns, etc., is a common pattern or technique, or it was in the olden days. There’s a reason why they are switching, right?
In the ancient days, Menus and their options were individual HTML files. Every button or link to perform a specific action would redirect to an HTML file.
However, that old pattern was only used for components like a Menu. But Microsoft clearly didn’t understand that.
They used an HTML file with React for every simple component. Every HTML file required JavaScript. And they shared this JavaScript code with every team as bundles of code.
Microsoft embedded multiple HTML pages (in React apps) into their browser to control their entire UI. And now, they are looking for a solution to both problems.

{% embed https://store.afankhan.com/l/200-JS-Questions-Concepts-Resources %}
---
## The Solution
**For starters, React wasn’t the problem**. Microsoft implemented it incorrectly.
A bundle should work for a specific webpage and serve its purpose independently. Each page could have an individual bundle or collection.
However, when you share the same bundle or files across the work of different teams, you must expect chaos. Every team accesses and modifies the same bundles.
The outcome was expected. React wasn’t meant for what they were doing with it. React isn’t slow. But you cannot expect it to be blazing fast when you create dozens of instances.
Microsoft came up with a solution to a problem they created. They created a custom framework.
Microsoft announced WebUI 2.0 (not Web 2.0). A markup-first architecture. It solves the problem of large code bundles by minimizing their size and the amount of JavaScript that runs during the initialization path.
Microsoft has started using this new architecture to solve both problems I stated earlier. They used React for the wrong purpose, forgot that React Native exists, and solved a manufactured problem.
First, they used individual HTML files for each component with React inside them. Then, they offloaded the JavaScript code required by each HTML file into one bundle shared by ten other teams.
And now, they don’t use React anymore. What do you think about this?

Here's the thing. Tools like ChatGPT can do the groundwork for you. But making sure your content feels relatable and personal? That's where you come in.
In this guide, we'll show you how to weave in your unique voice and perspective into AI-generated content --- so it feels like it's coming from you, not a machine.
💡 New to AI tools? Check our [AI prompt guide](https://www.taskade.com/blog/ai-prompting/) to master the basics.
🧐 Why Would You Want To Humanize AI Content?
---------------------------------------------
AI-generated content is everywhere.
But what exactly does "AI-generated" even mean? 🤔
It's pretty much what it sounds like --- content that's not created by a human but by a machine. More specifically, by large language models (LLM) which are essentially clumps of sophisticated algorithms trained on vast amounts of data.
🤔 What makes us human? Psychologist Daniel Dennett and philosopher John Searle believe that the key ingredient AI lacks (yet) is consciousness. While LLMs can imitate human creativity, they are missing that inner experience we humans have --- the awareness that goes beyond just processing data. It's what makes us, well, us.
This could be text or images generated using ChatGPT, or it could be snippets of code and even music. Anything that can be digitized and replicated by learning patterns can be produced by AI.
And according to Google, the oracle of content creators, it's not entirely bad.
The Big G suggests that when used ethically, AI can enhance the content quality. If it meets the standards of experience, expertise, authoritativeness, and trustworthiness (EEAT), it's welcomed on their platform.
So, are there any penalties for not following the rules?
Google's is pretty clear on that too.
If you're pumping out low-quality content to manipulate rankings, you're breaking the rules. This could get your content pulled from search results, which is exactly what happened to many sites after the [recent Google core update](https://blog.google/products/search/google-search-update-march-2024/).
That can hurt. Especially if you're in the content marketing business.
📉
Rankings matter, but so does perception.
Many people can instinctively tell when content is AI-generated. It may lack nuances and personal touch. Or it may rattle out the same robotic phrases (we'll get to that) that instantly give away its "non-organic" origins.
If readers sense that your content lacks authenticity, they will drop out and never come back. So, let's learn how to sprinkle in that human charm.
🤖 ➡ 🙋♂️ How to Humanize AI-Generated Content
-----------------------------------------------
### 1\. Provide a "Seed" for Context
AI can't read your mind (yet) It can, however, infer your intent. In other words, it can "guess" what you're asking based on patterns it has learned.
🤔
Most of the time, the results of this guesswork are disappointingly generic.
The output may say things like "it is advisable " without backing the advice with "science." It will veer off the topic, touching on peripheral themes. It may go broad, never quite nailing the point. The more obscure or recent the topic you're covering, the more likely AI is to trudge around.
Unless you want to entertain yourself with a short story about time-traveling dinosaurs ruling ancient Egypt, you need to start humanizing AI by providing context:
- 🟠 Give AI a starting point: Want to write an introduction to an article? Write the first sentence, and let AI build on top of that. It doesn't have to be Pulitzer-worthy; just lay down a few thoughts and ideas you're aiming for.
- 🟠 Ask AI to enhance, not create: Use AI to add to or refine your content. Ask it to finish your own paragraphs or generate its variations. You can even provide the full draft and ask for suggestions on structure or argumentation.
- 🟠 Provide examples and let AI fill in the blanks: The more details you provide in the initial prompt, the better --- think names, dates, places, facts. With context, AI will be less likely to slip into unhinged creative tangents.
### 2\. Tone it Down
Sometimes, AI is like that one friend who uses five adjectives when one will do. Fancy words, complex sentences, a smorgasbord of synonyms no one asked for.
✨
(see what we did there?)
AI's enthusiasm for sophisticated vocabulary might seem impressive. You may even think it will impress your readers. The problem is that the output may say a lot without really saying anything.
People don't always talk like they're writing an essay for their English Lit class. Most conversations we have each day are casual. They're simple, direct.
Unless you're writing a technical manual or a legal document, you need to simplify:
- 🟢 Opt for simple, relatable language: When giving AI instructions, be clear that you expect simple, conversational tone. You can use phrases like "explain this to me like I'm five," or "Write this as if you're telling a story to a friend." Tailor the style and language to your audience.
- 🟢 Cap the thesaurus: AI loves showing off its vocab. To keep it in check, ask AI to "use plain words," or "avoid complex sentences." Simple words will make your message clear and more relatable. No fancy dictionary needed!
- 🟢 Shorten the sentences: AI can get carried away with long, winding sentences. Steer it back by asking for "short sentences only" or to "get to the point quickly." Your readers will thank you.
### 3\. Fact-Check the Output
By 2026, 90% of online content will be generated by AI.
And how much of the stuff you read online is penned by artificial intelligence? Nobody really knows. But a recent study with respondents from sixteen countries found that 85% of people worry about online disinformation.
🔍
We're not going down the rabbit hole to explain the connection. But we can expect things will go from tricky to problematic really fast, really soon.
Unlike search engines which pull information from indexed sources, AI generates responses based on its training data. That means it doesn't always get the facts right and sometimes mixes reality with fiction in bizarre ways.
This is what the artificial intelligence industry calls "AI hallucinations."
A seasoned human writer will catch the hallucinations if they know the subject well. But considering how much content we create each day --- conservative estimates put it at around 328.77 million terabytes --- it's hard to make sure that everything AI generates is spot-on.
The good news is you can take a few steps to keep your content trustworthy.
- 🔵 Don't treat AI like Google: Tools like ChatGPT don't replace diligent research. They provide a good starting point, you still need to put in the work. The rule of thumb is: always make sure to cross-verify the output with direct sources or through additional research.
- 🔵 Develop a critical eye: Train yourself to spot potential AI hallucinations. Pay attention to any historical facts, specific data, or quotes --- these are areas where AI might slip up. If you can't cross-check the information, ask the AI point-blank where it got it from.
- 🔵 Tell AI to stick to the facts: Some AI models offer a "temperature" setting: a higher temperature results in more varied and creative outputs, while a lower temperature makes the responses more predictable. In more closed platforms like ChatGPT, you can simply include additional instructions in the prompt, e.g. "explain the photosynthesis based on your training data."
### 4\. Use the Lingo of Your Audience
Nine times out of ten, generic prompts yield content that's about as exciting as watching paint dry. You get broad, vanilla statements that could apply to just about anyone. Think stock photos where everyone's smiling 24/7.
🥱
Your AI-generated content needs a unique flavor.
If you're talking to finance pros, terms like "ROI" and "equity" should be part of the output they make sense in the context. If you're addressing programmers, the readers may expect terms like "debugging," "push," and "commit."
Who are you targeting with your content?
Are they industry experts, casual enthusiasts, or complete novices?
What language (jargon, technical terms) do they use?
Once you know who your audience well, tweak your prompts accordingly:
- 🟣 Set specific parameters: Instruct AI on the language level and jargon appropriate for your audience. Make it crystal clear who the content is targeting. You may request industry-specific terminology for healthcare professionals or legal language for lawyers.
- 🟣 Refer to style guides: Give your AI a specific style manual to follow. If you're targeting academics, set it to use APA for psychology buffs or MLA for the literature crowd. Consistency in citation will build credibility and make the output more consistent.
### 5\. Add Real-Life Examples and Stories
When AI writes, it doesn't consider the reader's emotions or experiences. It delivers the what, but not the why or the how that people can see in their day-to-day lives.
🪞
Humanizing AI means you need to add elements your audience can relate to.
For instance, if you're covering a fitness app, don't just list the features --- tell the tale of someone who hit their daily 10,000 steps and improved their health.
If you're breaking down a budgeting tool, go beyond the specs. Share a personal success story how it helped Emma kiss her debt goodbye.
You get the idea.
Details matter --- real names, real problems, real results.
With these changes, your AI-generated text will mirror the conversations your readers have in their daily lives. They'll see themselves in the stories you tell.
- 🔴 Inject personal anecdotes: Find a real story that matches your point. Maybe it's your own, maybe it's a customer's. Just a few lines about a real experience can turn dull into relatable.
- 🔴 Add concrete examples: Stats and facts? Sure, they have their place. But follow them up with a concrete example. "This widget saves time" becomes "Meet John, who now enjoys breakfast with his kids because our widget cut his admin work by half."
- 🔴 Sprinkle an emotional touch: Tap into what you want your readers to feel. Share stories that hit home and genuine connections. Whether it's a tale of success or a heartfelt moment, emotions makes help your your message stick and build rapport.
### 6\. Rewrite Overused Words and Phrases
In the realm of content creation, AI tools play a significant role in enhancing and augmenting the complexity and diversity of language...
Sounds familiar? That right there is AI at its best.
🤖
AI models are only as good as their training data. And since they are trained on vast collections of human-generated content, they inherit our linguistic ways.
If you've used AI tools a few times, you already know what to look for.
Words and phrases like "meticulous," "navigating complexities," and "in the realm of" pop up often, and they make AI-generated text mechanical or overly formal.
Now, don't get us wrong, there is a place for sophisticated language. But most of the time, you're fine with simpler and relatable language.
The solution? Tell AI what words and phrases to avoid.
Compile a list of common clichés and overused expressions specific to the AI model you're using. When you're done, feed it to AI with an instruction to stay clear (we'll revisit this point in a moment).
### 7\. Avoid Using AI Detection Tools
Just because something sounds polished doesn't mean it's AI-generated.
Since GPT 3.5 and GPT-4 launched in late 2022 and early 2023, a ton of "AI detector" services have claimed to be able to flag content written by AI.
In a plot twist, one of those tools even flagged parts of the U.S. Constitution --- that centuries-old cornerstone of American law--- as AI-generated.
📜
Now imagine you're a student. You spend a whole night pouring your heart into an essay, fueled by liters of coffee. But when you submit your work, your professor runs it through AI detection tools.
The outcome? Doubt over its originality or, well... failing grade.
(to be fair, some students are using AI to write essays)
AI-detection recognizes patterns, and AI writing has patterns. But so does human writing. And so far, there hasn't been a reliable way to tell them apart.
Here's what you should do instead:
- 🟤 Use common sense: Don't let tools dictate the authenticity of your content; trust your instincts. You know what sounds real and what doesn't. After all, you're the expert in your field, and you know your audience better than any algorithm (right, right?).
- 🟤 Emphasize personal insights: Inject your unique perspectives or personal anecdotes into your writing. AI writing tools may not easily replicate these personalized elements, which can help your work stand out.
- 🟤 Blend sources and styles: Mix various sources and stylistic elements in your writing. Use quotations, citations, and vocabulary that reflects wide reading beyond typical AI training sets. Oh, and AI sucks at humor, so try your hand at that.
🐑🤖 Building An Agent In Taskade To Humanize Your AI-Generated Content
-----------------------------------------------------------------------
Everything we've covered so far falls into the "common sense" bag. But did you know that you can actually use AI to make your content more human?
"Wait, aren't we supposed to be careful with AI?"
Yes, but it's all about how you use it.
If you're new to [Taskade AI agents](https://www.taskade.com/ai/agents), here's a tl;dr.
### What Are Custom AI Agents in Taskade?
An agent is a small, specialized tool you can customize and train to perform specific tasks. It usually represents a specific role a human would occupy, e.g. editor, content strategist, engineer, or SEO expert.
Taskade features dozens of agent templates you can start with, each with a set of customizable commands that speed up work (more on that in a bit).
You can run agents within your projects or interact with them in a chat.
Here's a quick video introduction that will help you get up to speed.
Pretty cool, huh? Now, let's set one up.
### Create Your First Agent
Here's a typical content creator scenario.
You want to produce a weekly newsletter that highlights industry trends, news, and tips in a casual, yet authoritative tone.
We'll set up an agent that will act as a hyper-personalized writing assistant.
First, head over to your [workspace](https://help.taskade.com/en/articles/8958483-create-a-workspace) and go to the Agents tab.
Once inside, click ➕ Create agent, pick the ✍️ Copywriter template, give your new agent a name and avatar (optional), and hit Create.
You're now in the Agent Settings menu.
### Train Your Agent
The Knowledge tab on the left gives you several options to train your agent.
You can attach previous newsletters as .pdf or .docx documents, or any web resources (web pages, blogs, YouTube videos) you want the agent to learn from.
Start by adding a few newsletter samples so the agent can learn from your past content --- what worked, what resonated, and the overall style.
At this stage, you may also want to upload a list of words and phrases you want the agent to avoid.
Now, about those custom commands.
### Define Custom Commands
Custom commands are the levers you pull to interact with agents. They come in a simple / + "command name" format that works anywhere inside Taskade.
For instance, you may create a command to generate topic ideas based on trending keywords, or another to refine language for clarity and engagement.
Each command can be triggered in the project editor or in the chat.
The ✍️ Copywriter agent already includes several generic commands. You can customize each of them or add your own to the pool.
And now for the fun part. 🥳
### Use the Agent
Head back to the Agents tab and choose the ✍️ Copywriter agent from the list.
Once in the Agent Chat, describe the newsletter you're working on.
You may include details like:
- 👤 Target audience
- 💡 Newsletter topic
- 📐 Format and length
- 💬 Key messages
- 📣 Call-to-action
- 🚦 Tone and style preferences
Don't forget to instruct the agent to imitate the style of the uploaded documents.
Finally, ask the agent to generate and press ⌨️ Enter.
The agent will craft a personalized newsletter draft based on the guidelines.
Experiment with agent settings to match the type of content you'r working on. Play with the tone, style, and agent knowledge to match your unique style.
And that's it! 🥳

🪄 Giving Your AI Content That Human Touch
------------------------------------------
Time to wrap it up.
Whether we like it or not, LLMs have transformed the entire creative landscape. And companies like OpenAI, Nvidia, Amazon, Google, and others are already cooking up even more impressive tech as we're writing these words.
So, have humans fallen down the creative food chain?
Not so fast. AI-generated content may be affordable and easy to scale. But it can't replace the human touch that makes it stand out from the noise.
So keep creating content that not only informs but also connects and stands the test of time. Lean on AI for support, but let your own voice shine through. | taskade |

"use client";
import React from "react";
import { motion } from "framer-motion";
export default function Template({ children }: { children: React.ReactNode }) {
return (
<motion.div

1,885,319 | Step-by-Step Guide to Setting Up Stellar Validator Node | Note: The tutorial will guide you to set up three validation nodes. The tutorial is brief... | 0 | 2024-06-12T08:17:34 | https://dev.to/overcat/step-by-step-guide-to-setting-up-stellar-validator-node-3egk | stellar, devops, blockchain, tutorial | ## Note:
- The tutorial will guide you to set up three validation nodes.
- The tutorial is brief and should help you set up a node within 15 minutes (excluding time for synchronization).
- I will not explain in detail the reasons for each step here, please refer to [the detailed documentation](https://developers.stellar.org/network/core-node) provided by SDF for more information.
- You need to have a basic understanding of Stellar.
- You need to have a basic understanding of Linux.
- Some community members requested a simpler setup guide, so I wrote this tutorial hoping it helps. If you have any questions, feel free to ask in [the Stellar Dev Discord](https://discord.com/invite/stellardev).
## Prerequisites:
- Three servers with Ubuntu 22.04 installed. You can find the hardware requirements [here](https://developers.stellar.org/network/core-node/admin-guide/prerequisites).
- A domain name; we assume your domain is `example.com`.
- Three Stellar accounts for the nodes. We assume the account for node A is `GA`, for node B is `GB`, and for node C is `GC`. Their corresponding private keys are `SA`, `SB`, and `SC`. You need to activate these three accounts on the network and [set their home domain](https://stellar-sdk.readthedocs.io/en/stable/api.html#stellar_sdk.transaction_builder.TransactionBuilder.append_set_options_op) to `example.com`.
## Let's get started
### Setup domain
- Point `core-live-a.example.com`, `core-live-b.example.com`, and `core-live-c.example.com` to the IP addresses of nodes A, B, and C, respectively.
- Point `history.core-live-a.example.com`, `history.core-live-b.example.com`, and `history.core-live-c.example.com` to the IP addresses of nodes A, B, and C, respectively.
- Point `example.com` to any server; it can be the IP address of node A, B, or C, or it could be another server. Here, we assume it points to the IP address of node A.
### Setup Stellar Core
#### Add the Stellar repository
```bash
sudo curl -fsSL https://apt.stellar.org/SDF.asc -o /etc/apt/keyrings/SDF.asc
sudo chmod a+r /etc/apt/keyrings/SDF.asc
echo "deb [signed-by=/etc/apt/keyrings/SDF.asc] https://apt.stellar.org $(lsb_release -cs) stable" | sudo tee -a /etc/apt/sources.list.d/SDF.list
sudo apt update
```
#### Install PosttgreSQL and Stellar Core
```bash
sudo apt install postgresql postgresql-contrib stellar-core
```
#### Setup PostgreSQL
Let's create a new database user and database.
```bash
sudo -u postgres psql -c "CREATE ROLE stellar WITH LOGIN;"
sudo -u postgres psql -c "CREATE DATABASE stellar OWNER stellar;"
```
#### Add a custom cp command
This is to allow `Nginx` to have permission to read these files.
```bash
sudo nano /usr/bin/stellarcp
# Add the following content
# Save the file
```
```bash
#!/bin/bash
# Check the number of arguments
if [ "$#" -ne 2 ]; then
echo "Usage: stellarcp <source_file> <destination_file>"
exit 1
fi
# Copy the file
cp "$1" "$2"
# modify the permissions of the destination file
chmod 0644 "$2"
```
```bash
sudo chmod +x /usr/bin/stellarcp
```
#### Configure Stellar Core
```bash
sudo -u stellar nano /etc/stellar/stellar-core.cfg
# Add the following configuration
# save the file
```
You need to talk care of the `EDIT ME` in the configuration file. In addition, you can use https://stellarbeat.io to search for existing nodes on the network in order to select suitable validator nodes to add to your own configuration file.
In the example configuration file, the three nodes of `lightsail.network` are set by me. You can keep or remove them according to your preference.

NODE_HOME_DOMAIN="example.com"
# Only nodes that want to participate in SCP should set NODE_IS_VALIDATOR=true.
# Most instances should operate in observer mode with NODE_IS_VALIDATOR=false.
# See QUORUM_SET below.

# if false will look for CATCHUP_RECENT for catchup settings
# If you set it to false, then you should be able to complete the synchronization in a short time.
CATCHUP_COMPLETE=false
# DEPRECATED_SQL_LEDGER_STATE (bool) default false
# When set to true, SQL is used to store all ledger state instead of
# BucketListDB. This is not recommended and may cause performance degregradation.

# HISTORY
# Used to specify where to fetch and store the history archives.
# Fetching and storing history is kept as general as possible.
# Any place you can save and load static files from should be usable by the
# stellar-core history system. s3, the file system, http, etc
# stellar-core will call any external process you specify and will pass it the
# name of the file to save or load.
# Simply use template parameters `{0}` and `{1}` in place of the files being transmitted or retrieved.
# You can specify multiple places to store and fetch from. stellar-core will
# use multiple fetching locations as backup in case there is a failure fetching from one.
#
# Note: any archive you *put* to you must run `$ stellar-core new-hist <historyarchive>`
# once before you start.
# for example this config you would run: $ stellar-core new-hist local
# this creates a `local` archive on the local drive
# NB: this is an example, in general you should probably not do this as
# archives grow indefinitely
[HISTORY.local]
get="cp /var/lib/stellar/history/{0} {1}"
put="stellarcp {0} /var/lib/stellar/history/{1}"
mkdir="mkdir -p /var/lib/stellar/history/{0}"
```
{% enddetails %}
#### Initialize the database
```bash
sudo -u stellar stellar-core --conf /etc/stellar/stellar-core.cfg new-db
```
If the configuration is correct, you will not see any error message.
#### Initialize the history archive
```bash
sudo -u stellar stellar-core --conf /etc/stellar/stellar-core.cfg new-hist local
```
If you see `cp: target '/var/lib/stellar/history/.well-known/stellar-history.json' is not a directory`, don't worry, it's not your fault. You can ignore this message.
#### Start Stellar Core
```bash
sudo systemctl restart stellar-core
```
Check the status of Stellar Core:
```bash
sudo systemctl status stellar-core
```
You should see `Active: active (running)`. If you see other messages, please check the log file `/var/log/stellar/stellar-core.log`.
#### Check the sync status
```bash
stellar-core --conf /etc/stellar/stellar-core.cfg http-command 'info'
```
You should see the `state` is `Catching up`, now, you need to wait until the `state` is `Synced!`. Because we have set `CATCHUP_COMPLETE` to `false`, the validator will not synchronize the complete historical records. You should be able to complete the synchronization in a few minutes or hours.
### Publishing History Archives
Next, let's publish the history archives. We'll use Nginx to publish the locally stored history archives. You can use other methods to publish the history archives, such as publicly exposing the AWS S3 bucket.
The following example publishes history archives on node A. For nodes B and C, you need to repeat this process, adjusting the configuration file `EDIT ME` sections and replacing the domain information appropriately.
#### Install Nginx and Certbot
```bash
sudo apt install nginx certbot python3-certbot-nginx
```
#### Setup Nginx
```bash
# Create a new site configuration file, replace `history.core-live-a.example.com` with your domain
sudo nano /etc/nginx/sites-available/history.core-live-a.example.com
# Add the following configuration
# Save the file
```
```text
server {
listen 80;
root /var/lib/stellar/history/;
# EDIT ME: replace `history.core-live-a.example.com` with your domain
server_name history.core-live-a.example.com;
# do not cache 404 errors
error_page 404 /404.html;
location = /404.html {
add_header Cache-Control "no-cache" always;
}
# do not cache history state file
location ~ ^/.well-known/stellar-history.json$ {
add_header Cache-Control "no-cache" always;
try_files $uri =404;
}
# cache entire history archive for 1 day
location / {
add_header Cache-Control "max-age=86400";
try_files $uri =404;
}
}
```
#### Enable the site
```bash
sudo ln -s /etc/nginx/sites-available/history.core-live-a.example.com /etc/nginx/sites-enabled/
# Test the configuration
sudo nginx -t
# Reload Nginx
sudo nginx -s reload
```
#### Setup SSL Certificate
```bash
sudo certbot --nginx -d history.core-live-a.example.com
```
### Setup Stellar TOML
Here we will set up a `.well-known/stellar.toml` file to publish node information. Earlier, we pointed `example.com` to the IP address of node A, so we will set up this file on node A.
```bash
sudo mkdir -p /var/www/example.com/.well-known/
sudo nano /var/www/example.com/.well-known/stellar.toml
# Add the following content
# Save the file
```
```toml
# See https://github.com/stellar/stellar-protocol/blob/master/ecosystem/sep-0001.md for more information.

With round-the-clock medical care and compassionate support, clients navigate through withdrawal symptoms with strength and resolve, building the basis for their recovery path.
Therapy, in which patients participate in a range of therapeutic modalities catered to their particular needs and circumstances, is essential to the recovery process.

Through individual counseling sessions, group therapy, and psychoeducational workshops, participants explore the root causes of their addiction, develop coping strategies, and learn critical life skills to navigate the challenges of recovery. Therapists and counselors provide guidance, empathy, and encouragement, creating a safe and supportive environment for healing and growth.
Nasha Mukti Kendra in Himachal Pradesh offers comprehensive support services to facilitate successful reintegration into society outside the walls of the treatment facility. Vocational training, educational programs, and employment assistance empower individuals to build meaningful and sustainable livelihoods, fostering independence, self-sufficiency, and a sense of purpose beyond addiction.
Additionally, the center emphasizes the importance of nutrition, physical fitness, and overall wellness in supporting recovery and maintaining sobriety. Nutritional counseling, exercise programs, and wellness workshops equip individuals with the knowledge and tools to nourish their bodies, strengthen their minds, and enhance their overall health and vitality.
In addition, the center provides a wide range of support services for family members impacted by addiction and acknowledges the vital role that community and family play in the healing process. Families can heal from the effects of addiction, mend relationships, and create a supportive environment for recovery with the help of family therapy sessions, support groups, and educational workshops.
As individuals advance through their recovery journey, Nasha Mukti Kendra remains a consistent source of support, delivering aftercare services and alumni programs to guarantee continuous success and prevent relapse. People get the direction, support, and accountability they need to stay sober, deal with life's obstacles, and enjoy their newfound freedom through ongoing counseling, peer support, and community involvement.

1,885,195 | Recursion Explained: Mastering the Concept Step-by-Step | What is Recursion? Recursion is a way of programming where a function calls itself to... | 0 | 2024-06-12T08:09:58 | https://dev.to/fazilchengapra/recursion-explained-mastering-the-concept-step-by-step-4j1b | recursion, programming, datastructures, algorithms | ## **What is Recursion?**
`Recursion is a way of programming where a function calls itself to solve smaller parts of the same problem.`
```c
int fun() {
printf("This function does not stop!!!.\n");
fun(); // Recursive call without a base case
}
int main() {
fun();
return 0;
}
```
This is not a recursive program because a `recursive program is expected to have a base case.`
##**How does a base case function in recursion?**
`A base case helps stop the recursion in programs.`
**Example:-**
```c
int factorial(int n) {
if(n == 0){
return 1; // base case
}
return n * factorial(n - 1);
}
int main() {
int n = 3;
int result = factorial(n);
printf("%d", result);
return 0;
}
```
```
Output:
6
```
## **How does this program work? Step-by-step explanation:-**
##**Step1:-**
```c
int factorial(3) {
if(3 == 0){ // false
return 1; // base case
}
return 3 * factorial(2); // 3 - 1 = 2
}
int main() {
int n = 3;
int result = factorial(3); // n = 3
println("%d", result);
return 0;
}
```
**Call the main function to the factorial function, passing a parameter n.**
##**Step2:-**
**factorial(3) called to factorial(2)**
```c
int factorial(2) {
if(2 == 0){ // false
return 1; // base case
}
return 2 * factorial(1); // 2 - 1 = 1
}
```
##**Step3:-**
**factorial(2) called to factorial(1)**
```c
int factorial(1) {
if(1 == 0){ // false
return 1; // base case
}
return 1 * factorial(0); // 1 - 1 = 0
}
```
##**Step4:-**
**factorial(1) called to factorial(0)**
```c
int factorial(0) {
if(2 == 0){ // true
return 1; // base case
}
return 0 * factorial(-1); // 0 - 1 = -1 *this line not executed*
}
```
##**Return values**
```c

In doing so, I discovered some essential VSCode extensions that have significantly enhanced my productivity as a React developer. The only rule for this list is that all these extensions are **React specific**. While they might be useful for other purposes, their main focus is React.
So, let's dive in.
---
These extensions will help by providing you with snippets. **_Snippets_** are predefined pieces of code that can expand into a complete code block with a single keystroke (_pressing the tab key in most cases_). These snippets can range from a single line to an entire file. By using snippets, you can condense whole files into a short abbreviation, making your coding experience much smoother.
### **1. ES7 React/Redux/GraphQL/React-Native Snippets**
This [extension](https://marketplace.visualstudio.com/items?itemName=dsznajder.es7-react-js-snippets) provides a comprehensive collection of snippets for React, Redux, GraphQL, and React Native. These snippets can significantly speed up your development process by allowing you to quickly generate commonly used code structures. For example:
- `rcc` creates a React class component skeleton.
- `rfc` generates a React functional component.
- `rnfce` snippets help you quickly set up React Native component with default export.
* _The list is endless_ . Explore [here](https://github.com/r5n-dev/vscode-react-javascript-snippets/blob/HEAD/docs/Snippets.md)
These snippets are highly customizable and cover a wide range of use cases, making your development more efficient.
### **2. React Hooks Snippets**
The [React Hooks](https://marketplace.visualstudio.com/items?itemName=AlDuncanson.react-hooks-snippets) snippet extension simplifies the addition of hooks in React by providing specific abbreviations:
- `ush` for `useState` initializes a state variable.
- `ueh` for `useEffect` sets up a side effect.
- `uch` for `useContext` accesses a context.
This extension is particularly useful because it focuses on React's hooks API, which is a core feature for functional components. It helps you quickly implement hooks without having to remember the exact syntax every time.
### **3. VSCode React Refactor**
[VSCode React Refactor](https://marketplace.visualstudio.com/items?itemName=planbcoding.vscode-react-refactor) allows you to refactor your code by extracting parts of it into separate components. This can be particularly useful when your component becomes too large and you want to break it down into smaller, more manageable pieces. For example:
- Select a piece of JSX code.
- Right-click and choose "Refactor".
- Extract it into a new component.
This extension supports TypeScript and ensures that your extracted components are correctly imported and used, streamlining your refactoring process.
### **4. Paste JSON as Code**
[Paste JSON as Code] (https://marketplace.visualstudio.com/items?itemName=quicktype.quicktype) allows you to convert JSON objects into code. This is especially useful when dealing with APIs that return JSON responses. For instance:
- Copy a JSON object.
- Use the command palette to choose "Paste JSON as Code".
- Convert the JSON into JavaScript or TypeScript code with type definitions.
This extension helps in quickly transforming JSON data into usable code structures, saving time and reducing errors.
### **5. SVG Gallery**
[SVG Gallery] (https://marketplace.visualstudio.com/items?itemName=developer2006.svg-gallery) is an excellent tool for managing SVG files in your projects. It allows you to preview SVG files directly in VSCode, which can be particularly handy when dealing with multiple SVG assets. Features include:
- Preview SVGs within the editor.
- Copy SVG content as React components.
- Organize and manage your SVG assets efficiently.
This extension simplifies the process of working with SVG files, making it easier to integrate and manage vector graphics in your React projects.
---
While the above recommendations come from my subjective point of view and personal experience with these extensions, I urge you to install and experience them yourself. Each developer has unique needs and workflows, and these extensions might fit differently into your projects.
I encourage you to share some of the cool extensions that have enhanced your productivity. Remember, these are not the only extensions out there, and I'm always on the lookout for new tools to improve my workflow.
_This brings us to a thought-provoking question: **Are we creating lazy programmers by relying heavily on these extensions, or are we genuinely enhancing productivity and efficiency?** Share your thoughts and experiences. Let’s discuss whether these tools are crutches or catalysts for better development._
Until next time!......

> You don’t have to be an engineer to be be a racing driver, but you do have to have Mechanical Sympathy.
_Jackie Stewart, racing legend_
You don’t need to be a devops engineer to be a good software engineer. But it helps to have mechanical sympathy.
One of my favorite terms in the industry is mechanical sympathy. Its defined as having an understanding of how a tool you use, operates best ([AWS Well-Architected](https://wa.aws.amazon.com/wellarchitected/2020-07-02T19-33-23/wat.concept.mechanical-sympathy.en.html#:~:text=Mechanical%20sympathy%20is%20when%20you,Jackie%20Stewart%2C%20racing%20driver)).
A lot of engineers work or have worked or want to work in environments where tools like Kubernetes is being used to orchestrate the containers for the applications which they develop.
Even though most of these engineers do not need to concern themselves with interacting the underlying infrastructure. I argue that in most every case, having mechanical sympathy helps them become better engineers. They understand the limits, constraints and most importantly the capabilities for the system their application is running.
When I was transitioning from a Fullstack engineering role into a more backend specific role in 2017 one of my former coworkers held a mini workshop on Kubernetes during lunch at the company we used to work for. This workshop explained to me the basics of Kubernetes with a hands on approach and I started to gain some level of understanding what this was all about. The course gave me the exact amount of information that I needed to understand my company’s conversations around infrastructure and allowed me to build upon that knowledge and figure out more things on my own when I needed to. Since then I have worked on almost the entire spectrum of the stack and the transition was smoother because of the mechanical sympathy I had.
I honestly believe that gaining that small amount of mechanical sympathy helped me to become a better engineer than I would have been without it.
Another purpose of this post is that I want to tell you about how I want to pay it forward. I am creating a course which I am going to launch at the end of the summer. The course is a practical hands-on course on Kubernetes and like the name indicates it is designed to help you understand and make peace with this controversial and complicated subject. You can find it at https://zenkubernetes.com.
If this is something that you think might be useful to you feel free to sign up to the mailing list for a earlybird special discount.
P.S.
The course is still in closed beta but any feedback you might have on the topics or modules is greatly appreciated.

### Introduction
In recent years, the landscape of application development has undergone a significant transformation. The rise of low-code platforms is revolutionizing how applications are built, deployed, and maintained.
These platforms are designed to simplify and democratize the development process, enabling individuals with little to no programming experience to create functional applications.
This article delves into the world of low-code development, exploring its benefits, key features, leading platforms, use cases, and the future of this transformative approach.
## What are Low-Code Platforms?
Low-code platforms provide a visual development environment where developers can create applications through graphical user interfaces and configuration instead of traditional hand-coded programming.
They reduce the amount of manual coding required, thereby accelerating the development process.
Low-code platforms are designed to be accessible to both professional developers and business users, often featuring drag-and-drop components, pre-built templates, and reusable modules.
### The Rise of Low-Code Development
The growing popularity of low-code platforms is driven by several factors:
1. **Demand for Rapid Application Development (RAD)**: Businesses are under constant pressure to innovate and deliver solutions faster. Low-code platforms enable rapid prototyping and development, reducing time-to-market.
2. **IT Skills Shortage** : There is a global shortage of skilled developers. Low-code platforms empower non-developers to build applications, alleviating the burden on IT departments.
3. **Cost Efficiency** : Traditional development can be expensive due to the need for specialized skills and lengthy development cycles. Low-code platforms reduce development costs by streamlining the process and utilizing existing resources more effectively.
4. **Agility and Flexibility** : These platforms allow for quick iterations and changes, helping organizations adapt to evolving business needs and market conditions.
5. **Innovation and Experimentation** : By lowering the barriers to entry, low-code platforms encourage experimentation and innovation within organizations, fostering a culture of continuous improvement.
### Key Features of Low-Code Platforms
**Visual Development Interface **
A hallmark of low-code platforms is their visual development interface, which allows users to design applications using drag-and-drop components. This intuitive approach simplifies the development process and makes it accessible to non-technical users.

If you're part of the neurodiverse clan, you know the frustrations of missed deadlines, constant distractions, and car keys that sprout legs (metaphorically).
There are many ways to overcome those challenges. But offloading the grunt work to AI is one of the most effective strategies we've come to love.
Here's everything you need to know to get started. 👇
The Challenges of ADHD in Productivity
--------------------------------------
Let's start with the question of the day: "What is ADHD?"
Think of ADHD (attention deficit hyperactivity disorder) as a unique brain wiring. It's a state in which your mind constantly seeks new stimuli.
Imagine you're really into a book, totally hooked. The next thing you know, you're scrolling through your phone, with no clue how you got there.
Your brain's just hunting for the next buzz.
This may not seem like a big deal.
After all, the little distractions happen to everyone from time to time. But for someone with ADHD, the effort to focus is much greater.
Here are a few "features" (not bugs) that come with the ADHD brain:
- ⏰ Difficulty in managing time and meeting deadlines.
- 🔀 Struggles with organizing and prioritizing work.
- 🔥 Task switching and starting new tasks before finishing old ones.
- 🤷♀️ Misplacing things and forgetting about commitments.
- 👀 Overlooking or hyperfocusing on details (yes, you can do both!).
The good news is an ADHD diagnosis is not the end of the world.
There are ADHD coaches and therapists who specialize in working with the neurodiverse community. You can join support groups and online forums to share your experience. Or you can turn to technology to help you out.
🤖 Understanding AI and Its Role in ADHD Management
---------------------------------------------------
When we talk about AI, we can mean (at least) a couple of things.
There's the Hollywood type, ready to doom the world. And there's the real deal --- sophisticated large language models (LLMs) like GPT-4, Llama2, or Bart.
An LLM is a type of artificial intelligence system that can process and generate human-like content based on extensive datasets used in its training.
The purpose?
Anything from generating documents, answering questions, and assisting with language translation, to summarizing information. LLM can also simulate human-like conversations, but we'll get to that in a moment.
So, how does this help with ADHD?
AI can help you break down your to-dos into manageable chunks and shoot you reminders when deadlines creep up. Or it can conjure up tips and strategies for dealing with the daily overload.
Let's say you're working on a research paper.
One of the most daunting aspects is the planning stage --- outlining key sections, brainstorming arguments, and organizing thoughts.
These tasks require a lot of sustained focus, which means there are plenty of opportunities to fall down the rabbit hole of distractions.
AI can provide you with a "scaffolding for thoughts." It may outline key sections, generate ideas, and suggest real-world examples, just to name a few.
But that's just the beginning.
🧠🦾 AI-Powered Tools Inside Taskade Enhancing Productivity
-----------------------------------------------------------
Are you new to Taskade? Here's a tl;dr.

1,885,184 | CLASSES | TS | TypeScript Classes TypeScript adds types and visibility modifiers to JavaScript... | 0 | 2024-06-12T06:58:53 | https://dev.to/birusha/classes-ts-20o2 | webdev, typescript, beginners, programming | # TypeScript Classes
TypeScript adds types and visibility modifiers to JavaScript classes.
## Members: Types
The members of a class (properties & methods) are typed using type annotations, similar to variables.
```ts
class Person {
name: string;
}
const person = new Person();
person.name = "Jane";
```
## Members: Visibility
Class members also be given special modifiers which affect visibility.
There are three main visibility modifiers in TypeScript.
- **public** - (default) allows access to the class member from anywhere
- **private** - only allows access to the class member from within the class
- **protected** - allows access to the class member from itself and any classes that inherit it, which is covered in the inheritance section below
```ts
class Person {
private name: string;
public constructor(name: string) {
this.name = name;
}
getName(): string {
return this.name;
}
}
const person = new Person('Jane');
console.log(person.getName());
// console.log(person.name); person.name isn't accessible from outside the class since it's private
```
## Parameter Properties
TypeScript provides a convenient way to define class members in the constructor, by adding a visibility modifiers to the parameter.
```ts
class Person {
public constructor(private name: string) {
this.name = name;
}
getName(): string {
return this.name;
}
}
const person = new Person('Birusha');
console.log(person.getName());
// console.log(person.name); Property 'name' is private and only accessible within class 'Person'
```
## Readonly
Similar to arrays, the readonly keyword can prevent class members from being changed.
```ts
class Person {
readonly name: string;
public constructor(name: string) {
this.name = name;
}
getName(): string {
return this.name;
}
}
const person = new Person('John');
console.log(person.getName());
// person.name = 'Jill'; // Cannot assign to 'name' because it is a read-only property.
```
## Inheritance: Implements
```ts
interface Shape {
getArea: () => number;
}
class Rectangle implements Shape {
public constructor (
private readonly width: number,
private readonly height: number
) {}
getArea(): number {
return this.width * this.height;
}
}
const r = new Rectangle(4, 3);
console.log(r.getArea());
```
## Inheritance: Extends
```ts
interface Shape {
getArea: () => number;
}
class Rectangle implements Shape {
public constructor(
private readonly width: number,
private readonly height: number
) {}
getArea(): number {
return this.width * this.height;
}
}
class Square extends Rectangle {
public constructor(width: number){
super(width, width);
}
// getArea function is inherited
}
const s = new Square(40);
console.log(s.getArea());
```
## Override
When a class extends another class, it can replace the members of the parent class with the same name.
Newer versions of TypeScript allow explicitly marking this with the **override** keyword.
```ts
interface Shape {
getArea: () => number;
}
class Rectangle implements Shape {
public constructor(
public readonly width: number,
private readonly heigth: number
) {}
getArea(): number {
return this.width * this.heigth;
}
public toString(): string {
return `Rectangle[width=${this.width}, height=${this.heigth}]`;
}
}
class Square extends Rectangle {
public constructor(width: number) {
super(width, width);
}
// get area function inherited here
public override toString(): string {
return `Square[width=${this.width}]`;
}
}
const rectangle = new Rectangle(20, 4);
const square = new Square(30);
console.log(rectangle.toString());
console.log(square.toString());
```
## Abstract Classes
Classes can be written in a way that allows them to be used as a base class for other classes without having to implement all the members. This is done by using the **abstract** keyword. Members that are left unimplemented also use the abstract keyword.
```ts
abstract class Polygon {
public abstract getArea(): number;
public toString(): string {
return `Polygon[area=${this.getArea()}]`;
}
}
class Rectangle extends Polygon {
public constructor (
private readonly width: number,
private readonly heigth: number
)
{
super();
}
public getArea(): number {
return this.width * this.heigth;
}
}
const r = new Rectangle(43, 34);
console.log(r.getArea());
```

This means that JavaScript run tasks one at a time in a sequence from top to bottom. It goes through our code line by line and executes them as it goes. This process signifies that JavaScript is synchronous by default.
Synchronous code is much easier to read and write, as the execution flow is clear and easy to follow. On the flip side though, synchronous code can be blocking. This means that in case of a code that might take time to execute, like fetching data from an API; synchronous code will cause the program to wait for the data to arrive before moving on to the next lines of codes. This may lead to performance bottlenecks and waste of time.
Asynchronous code provides a way for us to write code such that codes that takes a while to execute does not block the rest of the execution thread to cause delay of execution. This is usually achieved by passing a callback function as a parameter to execute on the side while the time taking condition is being met. What Asynchronous code does is;
• execute the codes line by line,
• get to the asynchronous code,
• execute the code,
• set aside the callback function pending the required time for the function to run,
• execute next line(s) of codes,
• Execute callback when it is ready.
Asynchronous code are mostly used when fetching data from some database or API endpoints. Ussually, it takes a couple of seconds for these data to arrive from the server, hence we use asynchrounous code to ensure that the execution process is not blocked, pending the arrival of such data.
Another example of asynchronous code is the javascript setTimeout function. The setTimeout accepts a callback function that will be executed as soon as the stipulated time is completed.
Example;
```
console.log("line 1")
console.log("line 2")
setTimeout(() => {
console.log("line 3")
}, 1000)
console.log("line 4")
console.log("line 5")
console.log("line 6")
```
## HTTP requests
HTTP stands for hypertext transfer protocol. It is a set of rules and guidelines that guide how browsers and servers exchange information. Typically, HTTP requests involve making request to resources from a backend server and the resources get sent back as a response. HTTP requests are made to API endpoints. An Application Programming Interface (API) allows us to have access to data in another system. An endpoint is the specific URL we can use to interact with an API.
There are several types of HTTP requests, they include;
1. GET: for fetching data from a server
2. POST: for uploading or submitting data to a server.
3. DELETE: for deleting data.
4. PUT: for updating data.
5. PATCH: used to update parts of a data without replacing the data entirely.
6. OPTION: checking the HTTP methods available to a resource.
7. HEAD: getting information about data without retrieving the data
8. CONNECT: used for establishing a connection to a proxy server.
9. TRACE: used to test request path, for debugging purposes.
In this piece, we are going to focus on the GET request method. To illustrate http requests, we will be using the jsonplaceholder api https://jsonplaceholder.typicode.com.
Jsonplaceholder is a free api service that allows us to play around with http requests and receive json data in return.
## How to make HTTP request
There are a couple of approaches to handling http requests that have been made available over time. Some of them are;
• xmlHttpRequest object
• promises
• fetch api
• async await
• axios
• ajax etc.
We shall discus some of them.
xmlHttpRequest object
To make a request object, create a variable and assign the xmlHttpRequest object to it;
```
const xhr = new XMLHttpRequest();
```
The request object contains essential information about the request, such as the method, URL, headers, body, and other metadata. This object is what we will use to make a request from the browser. The xhr object comes with a couple of methods and properties.
First, we use the open method to specify the type of request we want to make and the endpoint we want to make it to.
```
xhr.open("GET", "https://jsonplaceholder.typicode.com/todos/");
```
Next, we use the send method to send the request.
```
xhr.send();
```
The response will be delivered to us in json format. json format text are strings that looks like an array of JavaScript objects, but are not objects.
Next we listen for the readystatechange event. The readystatechange event is fired whenever there is a change to the ready state of our request. The ready state represents the current stage of the request. The stages range from 0 to 4. With
0 meaning unsent;
1 meaning opened;
2 headers received;
3 loading
4 fully loaded and request completed.
In the readystatechange event listener we could do what operation we want to do.
```
xhr.addEventListener('readystatechange', () => {
console.log(xhr, xhr.readyState)
})
```
As it turns out, we can only do something with the response when the ready state is equal to 4. So we will do a check to see if the readystate is equal to 4
```
xhr.addEventListener('readystatechange', () => {
if (readystate === 4) {
console.log(xhr.responseText)
}
})
```
To make them accessible for presentation, we need to convert the json data into JavaScript objects and assign the outcome to a variable like so;
```
const todos = JSON.parse(xhr.responseText)
console.log(todos)
```
At this point, if we had sent the request to the wrong url, or there was a kind of error somehow there would still be no data returned to us.
**Status codes**
We would also need to also check for status codes, and verify that the status code is 200. Status codes are numbers that indicate the outcome of an HTTP request. Common status codes include;
• 200 – successful request
• 301-moved permanently to a new URL
• 403 – access denied
• 404 – page not found
• 408-request timed out
• 500-internal server error
• 503- service not available
Etc.
```
xhr.addEventListener('readystatechange', () => {
if (xhr.readyState === 4 && xhr.status === 200) {
const todos = JSON.parse(xhr.responseText)
console.log(todos)
} else {
console.log(`Error: ${xhr.status}`);
}
})
```
**With wrong url **
To make all of these codes more reusable, we will wrap them all up in a function and call that function when needed with a callback. The full code will be like;
```
const getTodos = (callback) => {
const xhr = new XMLHttpRequest();
xhr.open("GET", "https://jsonplaceholder.typicode.com/todos/");
xhr.send();
xhr.addEventListener('readystatechange', () => {
if (xhr.readyState === 4 && xhr.status === 200) {
const todos = JSON.parse(xhr.responseText)
callback(todos)
} else if (xhr.readyState === 4) {
console.log(`Error: ${xhr.status}`);
}
})
}
getTodos(callback(todos))
```
If we want to have access to the todos, and do some more things with them in the reusable form, we may have to pass in a callback function to the getTodos function. Then in the callback function we can do whatever we intend to do with the data, like displaying a list of the todos in our UI.
```
const getTodos = (callback) => {
const xhr = new XMLHttpRequest();
xhr.open("GET", "https://jsonplaceholder.typicode.com/todos/");
xhr.send();
xhr.addEventListener('readystatechange', () => {
if (xhr.readyState === 4 && xhr.status === 200) {
const todos = JSON.parse(xhr.responseText)
callback(undefined, todos)
} else if (xhr.readyState === 4) {
callback(`Error: ${xhr.status}`, undefined);
}
})
}
getTodos((err, todos) => {
const container = document.getElementById('container');
if (err) {
container.innerHTML = err;
} else {
for (i = 0; i < todos.length; ++i) {
let ul = document.createElement('ul');
let content = `<li> ${todos[i].id} . ${todos[i].title} </li>
<p> ${todos[i].completed}</p>`;
ul.innerHTML = content;
container.appendChild(ul);
}
}
})
```
Add a div with id of container to the HTML, and CSS as desired.
## Promises
JavaScript promise offers a cleaner and more easily maintainable way of handling asynchronous code. A promise is literarily an obligation to do something in the future. When a promise is made, there are three expected outcomes;
1. Pending: here we are still waiting for the promise to be fulfilled or not.
2. Resolve: meaning the outcome was successful and promise is fulfilled.
3. Reject: which means unfulfilled promise with unsuccessful outcome.
Syntax
```
const getData = new Promise((resolve, reject) => {
// asynchronous operation
if (success) {
resolve(result);
} else {
reject(error);
}
});
```
In most cases, we want something to happen when a promise returns successful, say we fetch some data; we want to do something with the data. If the data cannot be fetched, we also want to do something with that outcome as well. The promise approach helps us to handle these two instances with ease. We can call the getTodos function, and tack a .then method to it to handle success cases, and tack a .catch method to handle the error cases.
syntax
```
const getData = new Promise((resolve, reject) => {
// asynchronous operation
if (success) {
resolve(result);
} else {
reject(error);
}
});
getData().then(result => {
console.log(result)
}).catch(err => {
console.log(err)
})
```
## promise with xmlHttpRequest object
Back to our todos example from the xhr object, we would still create the xhr object and use the relevant methods. The major difference now is that rather than using callbacks to handle what will happen with the data received, or the error as the case may be, we will use the .then() and .catch to handle resolve and reject instances.
Syntax
```
const getTodos = (url) => {
return new Promise((resolve, reject) => {
const xhr = new XMLHttpRequest();
xhr.open("GET", url);
xhr.send();
xhr.addEventListener('readystatechange', () => {
if (xhr.readyState === 4 && xhr.status === 200) {
const todos = JSON.parse(xhr.responseText)
resolve(todos)
} else if (xhr.readyState === 4) {
reject(`Error: ${xhr.status}`);
}
})
})
}
getTodos("https://jsonplaceholder.typicode.com/todos/").then(todos => {
console.log(todos)
}).catch(err => {
console.log(err)
})
```
## promise with fetch API
The fetch API is a built in function that gives us a newer and cleaner way of accessing data asynchronously. In this case, we no longer need to define the xhr object or call the accompanying methods, or to check for ready state change. All of that is taken care of behind the hood by the fetch API.
You can tack a .then function on the fetch method to handle what to do in case of a resolve response, and a .catch method to handle errors.
Syntax
```
fetch("https://jsonplaceholder.typicode.com/todos/").then((response) => {
console.log(response)
}).catch((error) => {
console.log(error)
})
```
This will log out to us the response object, and not the exact data we intend to work with. To access the json data, we have to use the json() method on the response object and assign it to a variable. That variable will now allow us to do whatever we want with the data.
```
const todos = response.json();
return todos;
```
This will return to us another promise. To access the returned data, we will have to chain another .then() method and take the data as an argument.
```
fetch('todos.json').then((response) => {
console.log(response)
const todos = response.json();
return todos;
}).then(todos => {
console.log(todos)
}).catch((error) => {
console.log(error)
})
```
Another thing to note with the fetch API is that the fetch API checks for ready state change, but does not check for status code. Hence, if the readystate is 4, but status code is not 200, the promise will still resolve but you will not be able to access the data you want to access. So you have to somehow check to ensure that the status of your request is OK, and throw an error if it is not.
```
if (response.status !== 200) {
throw new Error("error! status: " + response.status)
}
```
If you try a non-existing address now, you can get a custom error message.
To make the code reusable, we can wrap the whole thing up in a function.
```
const getTodos = (url) => {
fetch(url).then((response) => {
if (response.status !== 200) {
throw new Error("error! status: " + response.status)
}
const todos = response.json();
return todos;
}).then(todos => {
console.log(todos)
}).catch((error) => {
console.log(error)
})
}
getTodos("https://jsonplaceholder.typicode.com/todos/")
```
## async and await
Another new introduction to javascript asynchronous programming is the use of async and await keywords. These keywords make it easier to chain promises together, and provide even simpler and easy to read and debug syntax for handling asynchronous operations.
The async keyword is used to declare that the function is an asynchronous function. Whereas the await keyword, is used to tell that the codes in the async function should wait for the response or rejection of the statement before proceeding with the rest of the function. The await keyword can only be used inside an async function.
Syntax
```
async function doSomething() {
const result = await getSomething(); // wait for the result
console.log(result); // continue with the rest of the code
}
// with arrow function
const doSomething = async () => {
const result = await getSomething(); // wait for the result
console.log(result); // continue with the rest of the code
}
```
So back to our getTodos example,
```
const getTodos = async () => {
const response = await fetch("https://jsonplaceholder.typicode.com/todos/");
console.log(response)
}
getTodos();
```
We would still need to use the json() method on the response;
```
const todos = await response.json();
return todos;
```
And also to throw an error if status code is not equal to 200;
```
if (response.status !== 200) {
throw new Error("error! status: " + response.status)
}
```
So now we will have;
```
const getTodos = async (url) => {
const response = await fetch(url);
if (response.status !== 200) {
throw new Error("error! status: " + response.status)
}
const todos = await response.json();
return todos;
}
```
To call this function with our desired url and chain the relevant response and error handling functions;
```
const getTodos = async (url) => {
const response = await fetch(url);
if (response.status !== 200) {
throw new Error()
}
const todos = await response.json();
return todos;
}
getTodos("https://jsonplaceholder.typicode.com/todos/")
.then(todos => {
console.log(todos)
})
.catch(err => {
console.log(err)
})
```
With the wrong address
## Summary
JavaScript is synchronous by default. This means that JavaScript executes code sequentially. But with data that requires some time to execute, there has to be some way to handle those instances without causing delay in execution or block the flow of execution.
There are different approaches available to handling these kinds of operations. Here, we discussed the xhr request object, promises, fetch, and async & await. These approaches were built on one another, as the methods improved over time. The newer approaches made the codes easier to write and read. Which will in turn make the codes easier to maintain and debug

Selenium RC was the original Selenium tool. It is a server that played a vital role in the evolution of Selenium. Selenium RC allows users to write application tests in various programming languages and supports.
Key features of Selenium Remote Control:
Selenium Remote Control facilitates the testing of web applications across different browsers and platforms. It enables test scripting in languages such as Java, C#, Perl, PHP, and Python. Selenium RC injects scripts into the browser to automate tasks.
**Selenium Server**
The Selenium Server is a standalone application that facilitates the execution of Selenium WebDriver tests. It includes Selenium Grid and Selenium RC functionalities. Selenium Server plays a pivotal role in:
Acts as a proxy server between the client and the WebDriver instance by receiving WebDriver commands for execution.
- Distributed testing to be executed on multiple machines or browsers simultaneously.
- Allows tests to be executed on different browsers and different operating systems running on remote machines.
- Integration with Selenium Grid to manage the distribution of test execution across multiple nodes connected to the grid.
- To add additional nodes to the Selenium Grid setup as needed. This enables efficient utilization of resources and faster test execution.
- Remote execution ensures running tests on a dedicated test environment. It does not need physical access to the machines or browsers.
- Page Object Model (POM)
- The Page Object Model is a design pattern commonly used in conjunction with Selenium. It enhances test maintenance and readability.
**Key aspects of POM**
- Object Repository: Represents web pages as classes and web elements as variables. Code Reusability: Promotes the reuse of code. It makes tests more maintainable and easier to understand.
- Separation of Concerns: Separates test logic from the implementation details of the web elements. It improves the robustness of test scripts.
**Conclusion**

1,885,305 | The New Era of Blockchain: How LinkNetwork is Reshaping the Public Blockchain Paradigm and Driving Web3 Innovation | In today’s blockchain market, the development of public blockchains has become the frontier of... | 0 | 2024-06-12T07:53:24 | https://dev.to/linknetwork/the-new-era-of-blockchain-how-linknetwork-is-reshaping-the-public-blockchain-paradigm-and-driving-web3-innovation-1kb2 |
In today’s blockchain market, the development of public blockchains has become the frontier of cryptographic technology innovation. Numerous public blockchain projects, such as Ethereum, Polkadot, EOS, etc., are each developing their unique technologies and application ecosystems, with competition continually intensifying. However, as the market evolves and technology matures, these public blockchains increasingly face challenges related to scalability, interoperability, security, and user privacy protection.
Current public blockchains generally face several core issues. Foremost among these is scalability; as the number of users and volume of transactions grow, many existing public blockchains struggle to effectively handle large-scale concurrent transactions, often leading to network congestion and rising transaction costs. Next, interoperability between chains is also a pain point. Operational barriers between different public blockchains restrict the flow of assets and data, hindering the formation of multi-chain ecosystems.
Moreover, security issues remain a critical focus of public blockchain technology. As value becomes concentrated, public blockchains become high-value targets for attacks. Protecting networks from threats such as 51% attacks, Sybil attacks, DDoS attacks, and smart contract vulnerabilities is a challenge that every public blockchain project must address. Additionally, as awareness of personal data protection increases, user demands for privacy protection are growing. Public blockchains must provide more stringent privacy measures to enhance user trust and system availability.
In the worldview of Web3, public blockchains are seen as the foundational platforms for building decentralized applications. To effectively integrate with the vast Web3 ecosystem, public blockchains need to provide robust functional support, including but not limited to efficient data processing capabilities, cross-chain asset interoperability, high security, and native privacy protection mechanisms. The future development direction of public blockchains should focus on enhancing their technical architecture and functionality to better serve decentralized finance (DeFi), non-fungible tokens (NFTs), decentralized social platforms, and other Web3 applications.
In this context, LinkNetwork has demonstrated its uniqueness. Through a series of technological innovations, LinkNetwork has addressed the core issues faced by existing public blockchains while providing solid foundational support for the vast Web3 ecosystem. LinkNetwork adopts the Proof of Stake Authority (PoSA) consensus mechanism, effectively balancing network decentralization, security, and processing speed, significantly enhancing the network’s scalability. Additionally, LinkNetwork incorporates an efficient cross-chain protocol that allows for the free flow of assets and data between different public blockchains, greatly enhancing its interoperability.
On the other hand, the technical architecture of LinkNetwork is designed to enhance user experience and meet the needs of enterprise-level applications. A core element is its revolutionary on-chain scaling solution, which, through innovative Plasma frameworks and subchain technology, greatly enhances the ability to handle large-scale concurrent transactions. This layered blockchain architecture enables the main chain to effectively offload non-critical transactions, maintaining core processing speed and security, while subchains can flexibly handle the demands of specific applications, achieving rapid responses and low-cost operations.
LinkNetwork has introduced advanced privacy protection technology — Zero-Knowledge Proofs (ZKP). This technology allows users to verify the validity of transactions without exposing any critical information, which is crucial for enhancing user privacy and building trust. Through this approach, LinkNetwork not only ensures the transparency and security of transactions but also protects user privacy, thus better adapting to the current market’s dual demands for privacy and security.
In addressing the security issues of smart contracts, LinkNetwork has adopted formal verification and static analysis techniques. These technologies can automatically detect vulnerabilities and logical errors in smart contract code, significantly enhancing the security of smart contracts. Using these methods, developers can ensure the reliability and security of their smart contracts before deployment, reducing security incidents caused by code errors, and supporting the vast content systems and economic and financial systems of Web3.
In the world of Web3, LinkNetwork is not just a public blockchain that provides infrastructure; it is also a platform that fosters innovation and connects different blockchain ecosystems. Through its cross-chain protocol, LinkNetwork provides a seamless interoperability interface between different blockchains, allowing assets and data to freely flow between various blockchains. This greatly promotes the development of decentralized applications (DApps) while enabling seamless interaction between different blockchain-based Web3 ecosystems and Web3 applications, accelerating the advent of the Web3 era.
Overall, LinkNetwork, through its innovative technological solutions, has maximized the functional thresholds of scalability, interoperability, security, and privacy protection, providing strong technical support and new application possibilities for the vast ecosystem of the Web3 world. As more developers and Web3 applications join the LinkNetwork ecosystem, we can anticipate a more open, secure, and prosperous on-chain future.

🚀 Today, let's delve into the world of Laravel comments using the fantastic package from `beyondcode`.
📁 This package allows seamless integration of commenting functionality into your Laravel applications. Users can comment on various entities like posts, articles, or any other model in your application.
Let's get started! 🌟
---
## Installation via Composer
`composer require beyondcode/laravel-comments`
The package will automatically register itself.
> You can publish the migration with:
```php
php artisan vendor:publish --provider="BeyondCode\Comments\CommentsServiceProvider" --tag="migrations"
```
> After the migration has been published you can create the media-table by running the migrations:
```php
php artisan migrate
```
> You can publish the config-file with:
```php
php artisan vendor:publish --provider="BeyondCode\Comments\CommentsServiceProvider" --tag="config"

We asked ourselves a simple question: "Why not make email work for us, not against us?" That's why we've built an email automation system that not only helps manage an unruly inbox, but it also integrates it into your workflow.
Here's everything you need to know to get started.👇
📬 Taskade's Automation Features Explained
------------------------------------------
A lot of email automation solutions out there just don't mesh well with how we work. You're either forced to choose between bulky extensions or standalone email apps that don't even "talk" to existing workflows.
Not exactly ideal, is it?
At Taskade, we took a different approach.
Unlike Zapier or IFTT, automations in Taskade are a native part of your work. There are no middlemen; it's just your messages, your projects, your rules.
[Taskade's automations](https://www.taskade.com/blog/ai-automation-agents/) live where you work to give you full control without context switching. You set them once, and they handle your emails, projects, tasks, or any other part of your workflow while you work on other things.
The question of the day is, what can you automate?
- ✉️ Internal and external communication
- 🤝 Client/employee onboarding
- 🗞️ Newsletter management
- 📣 Project updates and meeting reminders
- ✅ Task delegation
- ✏️ Content distribution
Of course, there are many more combinations you can try to make your work more effective. But before we get to that, let's warm up first.
🪚 Step-by-Step Guide to Automating Your Inbox
----------------------------------------------
Every Taskade automation starts inside a workspace or a folder.
If you're new to Taskade, here's a tl;dr.
🌳 A workspace is your HQ --- your projects live here. Folders are like drawers, they separate different work areas. Together with projects, they form a three-tier hierarchy that keeps your work in harmony.
With that out of the way, let's head to the Automations tab.
(psst... you'll find it at the top of your space)
Once inside, click ➕ Add automation and choose if you want to start from scratch or use a template. We'll pick the second option to show you around.
You're now in the automation editor.
Every automation consists of triggers and actions that follow the "If this happens, then do that" logic. Triggers start automations by monitoring for specific conditions; actions occur once the triggers' conditions are met.
It's that simple.
To create the first trigger, click the ➕ Add Trigger tile and pick one of the workflows from the list. Each automation can only have one trigger. Don't forget to connect your Gmail account first (you can use a personal or work email address).
Now, let's add a few steps and decide what will happen next.
Our automation will do the following:
1. Trigger when a task is assigned inside a project.
2. Send an email to notify the team.
3. Move the task to a group project titled "Priority List" for easier tracking.
Once you're done, save the changes and enable the toggle at the top.
Congratulations! Your first automation is ready! 🎉
And now, let's look at some popular workflows you can start with.
🪄 Example Workflows for Common Email Tasks
-------------------------------------------
### Autoreply to Emails
What's the biggest headache with email? Ask around, and you'll hear different answers. But for a lot of us, it's just trying to stay afloat in the endless stream.
But that's a thing of the past. You can set up an automation that will generate tailored (no more auto-responders!) replies to emails while you sip your morning coffee. Just to make your inbox one less thing to worry about.
The automation flow consists of:
1. 🔔 (TRIGGER) New Email: The trigger activates the automation sequence whenever a new email arrives in your inbox.
2. ✅ (ACTION) Generate with AI: Taskade AI creates a personalized and context-specific reply based on its system prompt.
3. ✅ (ACTION) Send Email: Taskade passes the AI-crafted response back to Gmail where it is automatically sent back to the sender.
### Generate Summaries of Emails with AI
Ever wished for a summary button for those lengthy emails?
With a dash of AI magic, you can create an automation that provides summaries of emails and feeds them into your Taskade projects. From tech updates to daily business tips, all neatly organized before you even brew your morning coffee.
1. 🔔 (TRIGGER) New Email: Activates on receiving a new email.
2. ✅ (ACTION) Generate with AI: This action uses a Taskade AI prompt to condense the email, extract key points, and summarize the content.
3. ✅ (ACTION) Add Task: The AI-generated summary is converted into a task and added to your Taskade project for easy access.
### Convert Emails into Action Items
"What's next?", "Do I need to do anything?", "What is the issue here?" Got those questions every time you open a new email? Let's sort that out.
This automation gives each email the star treatment. First, Taskade AI will read through incoming emails and pick out the tasks hidden in plain text. Then it will convert those email tasks into actionable items and drop them into a project.
1. 🔔 (TRIGGER) New Email: The automation kicks into gear with each new email. The email content will be analyzed in the next step.
2. ✅ (ACTION) Generate with AI: Taskade AI analyzes the content of the new email, identifying tasks and converting them into action items.
3. ✅ (ACTION) Create a Task: The Taskade AI output from the previous step is added as new tasks in a project of your choice.
### Create Complete Projects from Emails
Let's take it a step further.
Emails often include enough details to become standalone projects.
For example, an email outlining a new marketing campaign can include objectives, target demographics, key messages, and timelines. An email from a client might specify site structure and design preferences.
You can set up an automation that will set the stage for your team to take over.
1. ✅ (TRIGGER) New Email: Triggers when a new email is received.
2. ✅ (ACTION) Generate with AI: Taskade AI analyzes the content of the new email, identifying key details, tasks, people, and events.
3. ✅ (ACTION) Create Project: Transforms the email content into a comprehensive project, ready for team action and collaboration.
Of course, there are plenty of other ways you can use the email automation connector. Be sure to check our automation catalog for more ideas.
🔥 Advanced Email Automation Tips and Tricks
--------------------------------------------
Alright, we've covered the basics. Now let's dig into more advanced stuff.
### Automation with Custom AI Agents
Custom AI Agents are smart assistants you can train and deploy within Taskade projects. Each agent can have a unique personality, skills, and knowledge for tailored responses (check [custom AI agents documentation](https://help.taskade.com/en/articles/8958457-custom-ai-agents) to get started).
And the best part?
You can now integrate custom agents directly into automations flows.
For example, a custom agent can generate blog content based on assigned tasks, all in the unique voice of your brand. The automation will also push the new draft to your WordPress site so you can review and publish it.
1. 🔔 (TRIGGER) Task Assigned: The automation triggers when a task, e.g. with the topic of an article, is assigned to you or another project member.
2. ✅ (ACTION) Run Agent Command: Your custom agent will generate the content based on the topic. You can train the agent by adding custom commands, editing its system prompt, or uploading documents for reference.
3. ✅ (ACTION) Create Post: The content is added to the WordPress editor.
4. ✅ (ACTION) Send Email: Sends an email confirmation to the editor who's tasked with optimizing the content before it goes live.
### Lead Processing
It's Friday evening. You're winding down after a hectic week, dreaming about the weekend ahead. Suddenly, an email notification pops up. It's a new lead.
Exciting, right?
But also, a bit overwhelming. You think, "Can it wait until Monday?" But in the back of your mind, you know that tiny voice whispers, "Strike while it's hot!"
Instead, we will set up a flow that will: a) send a personalized email to the new lead, b) create a new task inside a project, and c) file the lead in Google Sheets.
1. 🔔 (TRIGGER) New Response: Activates when a new response is submitted through Google Forms or Typeform.
2. ✅ (ACTION) Generate with AI: Uses Taskade AI to analyze the response details and craft a personalized follow-up or thank-you message.
3. ✅ (ACTION) Send Email: Sends the AI-generated message.
4. ✅ (ACTION) Add Task: Transforms the new lead into a task.
5. ✅ (ACTION) Insert Row: Logs the details of incoming leads and their response into a Google Sheets spreadsheet.
### Schedule Automations
Want to run your workflows at intervals? Taskade allows you to [schedule automations](https://www.taskade.com/blog/schedule-automations-new-ai-agents/) to every hour, every day, every week, and every month.
For example, you could set up an automation to remind team members to submit their work hours, which will streamline administrative tasks.
1. 🔔 (TRIGGER) Schedule: Set the trigger frequency.

1,885,301 | Alien: The Past and Present of Communication Security and Its Paradigm Evolution | Communication security, a concept that has existed since the dawn of modern communication... | 0 | 2024-06-12T07:48:05 | https://dev.to/alien_web3/alien-the-past-and-present-of-communication-security-and-its-paradigm-evolution-209m |
Communication security, a concept that has existed since the dawn of modern communication technology, has grown increasingly important. Especially today, with the rapid development of digitization and globalization, it has become a critical issue in the field of information technology. From early telegraphs and telephones to today’s internet communications, every technological leap has brought new security challenges. We have witnessed the evolution from simple codes to complex encryption algorithms, from physical isolation to virtual private networks and cloud services. Each step reflects humanity’s relentless effort to ensure communication security while pursuing convenience.
At the turn of the 20th to the 21st century, with the proliferation of the internet and the development of mobile communication technologies, emails, instant messaging, and social networks became an integral part of everyday life. Although these tools have greatly facilitated communication, they have also exposed many security vulnerabilities, such as identity theft, data breaches, and network surveillance, with frequent occurrences. Due to these incidents, which pose a serious threat to the information security of individuals and businesses, there have been many voices around the world opposing instant messaging.
In response to these issues, technical experts and research institutions across various fields have invested tremendous efforts to develop more secure communication technologies to elevate human communication to a new level.
On the one hand, traditional encryption technologies, such as symmetric and asymmetric encryption, are widely used for secure data transmission; on the other hand, emerging technologies like end-to-end encryption are increasingly becoming a standard feature of instant messaging software, ensuring messages cannot be read or altered by third parties in transit between sender and receiver.
However, even the most advanced technologies can suffer from security vulnerabilities due to improper user operation or insufficient security policies by application and software service providers.
Moreover, many communication platforms may collect and analyze user data for commercial benefits, further intensifying public concern over communication security.
**Current Situation**
As we enter the third decade of the 21st century, with the rise of blockchain technology and the widespread adoption of digital identities, the field of communication security is presented with new developmental opportunities.
The decentralized nature and encryption mechanisms of blockchain technology offer a novel solution that can not only effectively defend against external attacks but also prevent service providers from misusing user data, truly addressing the issues of communication security and privacy protection at their core.
Today, the public’s awareness of privacy and data protection is growing stronger, and the demand for secure communication tools is higher than ever. As an emerging field in information technology, blockchain is gradually being developed as part of human communication, and an increasing number of communication applications based on blockchain encryption are emerging.
**Why has communication security become the foremost challenge as humanity steps into the digital era?**
After understanding the development and current state of communication security, let’s revisit why it is so critically regarded that it has become the primary challenge on humanity’s journey towards the digital era and the “Age of Trust.”
Firstly, digital communication technology, an indispensable part of modern society, affects the daily lives and work of billions of users worldwide. The concern is not only due to the frequent occurrences of security vulnerabilities and privacy breaches but also because these incidents are directly linked to the financial security of individuals, the trade secrets of businesses, and the security interests of nations.
In recent years, we have witnessed several shocking communication security incidents that have rocked the world. They have not only revealed the vulnerabilities of current communication technologies but also exposed the inadequacies of many platforms in protecting user data. We can trace the significance of communication security in these incidents that have had profound global effects:
**NSA Surveillance Incident:**
Event: In 2013, former CIA employee Edward Snowden exposed the secret surveillance program of the United States National Security Agency (NSA) known as PRISM, which involved the mass monitoring of phone and internet communications globally.
Scope of Impact: Leaked documents revealed that the NSA had monitored communication data from millions of individuals and businesses both within the United States and abroad.
Consequences: This incident sparked global concern and debate over the right to privacy and also had a serious impact on the diplomatic relations of the United States and its allies.
**Facebook Data Breach Incident:**
Event: In 2018, the data analytics firm Cambridge Analytica illegally accessed personal data of about 87 million Facebook users and used this information to influence electoral activities, including the 2016 U.S. presidential election.
Scope of Impact: Directly affected tens of millions of users worldwide, undermining trust in Facebook.
Consequences: Facebook faced scrutiny and hefty fines from governments around the world and was forced to strengthen its data protection measures on the platform. This incident also spurred reforms in global data protection regulations.
**Collapse of the Cryptocurrency Exchange Mt. Gox:**
Event: In 2014, Japan-based Mt. Gox, which was the largest Bitcoin exchange at the time, declared bankruptcy, stating that 850,000 bitcoins (valued at approximately $480 million at the time) were stolen due to security breaches on its platform.
Scope of Impact: Tens of thousands of users lost substantial funds.
Consequences: The incident shocked the global cryptocurrency market, resulting in a plummeting Bitcoin price. It compelled cryptocurrency trading platforms to strengthen security measures and triggered increased regulatory oversight of the cryptocurrency market by global regulators.
It is evident from these incidents that even the largest tech companies and the most trusted services cannot fully guarantee the security and privacy of communications. Each security incident raises public, business, and government concern for communication security to new heights and drives the continuous development and improvement of encryption technologies and security measures.
Communication security concerns everyone’s interests and relates to national security, economic development, and social stability. As technology advances and cyber attack methods evolve, the challenge of maintaining communication security becomes even more severe. Against this backdrop, establishing a new type of communication platform that can both ensure communication security and protect user privacy, such as the solutions provided by Alien, becomes particularly important and urgent.
**Widespread User Demands**
Globally, as cybersecurity incidents and data breaches become more frequent, users’ concerns about the security and privacy protection of communication apps have significantly increased. They require not only the security of messages during transmission but also hope that their data will not be misused or accessed without authorization by app providers. Additionally, with the increasing popularity of mobile payments and digital currencies, users are also demanding that communication apps integrate payment functions, expecting more convenient fund transfers while ensuring security.
**Alien: Reshaping the Future of Communication Security**
The emergence of Alien is not just a simple advancement in technology but a comprehensive revolution in the existing framework of communication security. By combining multi-layer encryption technologies and the decentralized features of blockchain, Alien can provide users with unprecedented security guarantees.
In terms of security upgrades, Alien categorizes them into three types:
**Upgrade of End-to-End Encryption — AlienSecure**
AlienSecure is a blockchain-based end-to-end encryption technology, specially designed for Alien, to ensure the security and privacy of data throughout the communication process. The key to this technology lies in its unique key management system, which completely decentralizes the storage and lifecycle management of keys, achieving high security and immutability.
Traditional encryption methods usually rely on centralized key management systems, which could become targets for attackers. AlienSecure eliminates the risk of a single point of failure by storing keys on a decentralized blockchain network. Each key is uniquely generated and bound to a specific communication instance, ensuring that only the communicating parties can access it.
1. In this model, when users attempt to access encrypted information, they must first verify their DID identity on the blockchain. Once verified, users can obtain the decryption key via a smart contract, ensuring that even the Alien platform itself cannot access the user’s private communications. It could even be said that as long as the blockchain network is not compromised, no one can access any communication information, nor can they decrypt it forcibly.
2. Decentralized Key Management: Blockchain Key Vault
One of Alien’s core innovations is its decentralized key management system, the Blockchain Key Vault. In this system, keys are no longer stored and managed by any single entity or server, but are distributed across the blockchain network, with keys dynamically generated and allocated by smart contracts during each communication. This method not only significantly reduces the risk of keys being stolen or lost but also ensures that unauthorized third parties cannot decrypt any communication content.
3. DID — Decentralized Identity Verification
Using decentralized identity verification (DID) technology, Alien creates a unique identity identifier for each user. This not only allows users to manage their identities and data without centralized service providers, but also ensures the security and non-forgeability of all users’ communication links at the identity verification level.
With these cutting-edge technologies, Alien has achieved a highly secure communication environment, where each feature is designed to enhance user trust and security. Alien aims to set a new industry standard for encrypted communication with these technologies, redefining modern communication security standards through unparalleled security features and user experience.
While it may not be possible to claim that communications are absolutely secure, Alien can provide true absolute privacy and communication protection. Alien is a communication tool truly belonging to the Web3 era, and with the regulatory-compliant communication protection solutions provided by AlienSecure, Alien is set to become one of the most attractive communication tools on the market. | alien_web3 | |

Hi Guys welcome back to target developers
my name is shivam sahu
I am Experienced angular frontend developer.
we have IT software projects available in below technologies-
If you need IT Software project whatsapp me 9752245608.
And also you can hire me for project freelance.
so guys in this part of video we will see -
In angular 17 how we can send simple object in the form of JSON format from frontend side to backend side.
Firstly we need to understand that how we can made simple object in
typescript so guys we will open typescript file and make myData object
with open and close curly braces under this we defined name qualification
technology so in this way we can create simple object.
So now we will convert myData object into json format. here you can see for this
inside ngoninit function we are using json.stringify method.
under this method we are passing mydata object which were created earlier.
and also you can see we are taking holding variable named as stringifieddata . Now we will console the result you can see on the screen.
you can observe here name has double quoted and manav also double quoted.
so we have successfully converted object to json object.
----
Now guys if there is a case where we have json object and we need to convert to simple object then what we will do ?
so in this case we will use JSON.parse("json object").
now lets see how we can achieve this -
you observe here stringifiedata variable holding json object so we will write json.parse function passing stringifiedata (json object).
now we will console the output. Yo can see on the screen we have succssfully converted json obect to simple object.
I this part of video we will see the during development of angular project sometimes we try to print object in html file but we observe that object is printing in the form of [object object] you can see on the screen.
so how we can unwrap this in html template so here we will use new angular concept that is json pipe.
so now lets see how we can achieve this ?
open typescript file you can see we have simpleobject named as myData now this myData try to print in html template so we will use pre tag here under this we use interpolation and type myData | json (json pipe).
note- for using json pipeyou need to import common module.
we have successfully unwrap [object object] using json pipe you can see output on the screen.

script 2 - Javascript string manipualtion interview questions.
Hi guys, Welcome back to Target Developers, I'm shivam sahu, and today we have an exciting video planned just for you
So, In today's video, we're going to explore Javascript string manipualtion interview question.
We're covering here coding interview questions and also you can download source code and word document from the
video description, so stay tuned
Before we dive in, make sure to subscribe and hit that bell icon so you never miss an update. If you enjoy this video, give it a thumbs up and share it with your friends
----start---
so guys firstly we will call function from this line named as reverseString, inside this function we are passing string value, which we want to reverse, here we can see we are passing my name shivam sahu.
Now guys we will create function, which we are trying to call,
inside this function we are taking variable which will hold string value i.e. shivam sahu
In next line we are declaring varibale named as reversedStr with empty string.
in next two lines you can see we are calculating string legth,
we can see we are getting legth 10 of given string. But we all know
that guys array start with index 0 so here we are iterating for loop from
length-1 and here we are giving condition i >=0 .
so in next line one by one we are getting character from end of string and the we are adding with empty string i.e. reversedStr.
so for loop will iterate until its fails and when it fails function will
return reversed string.
we are holding output in variable i.e. reversedString .
now we will console so you can see we have successfully reversed our given string.

A monorepo is a version control strategy where multiple projects, often including libraries, applications, and services, are stored in a single repository. This approach contrasts with a multirepo (multiple repositories) strategy, where each project or component is stored in its own repository.
## Key Concepts of Monorepos
**1. Unified Codebase**
In a monorepo, all projects and components share a unified codebase. This means that any changes made are immediately available to all related projects, facilitating synchronised updates and reducing the risk of version mismatches.
**2. Dependency Management**
Monorepos simplify dependency management by centralising dependencies in one place. Developers can manage shared libraries and tools more efficiently, ensuring consistency across projects.
**3. Code Reuse**
With all code housed in a single repository, code reuse becomes more straightforward. Common utilities and modules can be easily shared and maintained, reducing duplication and promoting best practices.
**4. Simplified Collaboration**
Monorepos foster collaboration by providing a single source of truth. Team members can see the entire project landscape, understand interdependencies, and contribute across multiple projects without switching contexts.
## Pros of Monorepos
- Easier to ensure all parts of the codebase are compatible with each other since they are developed together.
- Reduces the complexity of managing dependencies between projects. All projects can share common libraries and components without needing to manage these dependencies across multiple repositories.
- Promotes sharing of code between projects, which can lead to more efficient development and maintenance.
- Large-scale refactoring and architectural changes are easier to perform across the entire codebase, ensuring consistency and reducing technical debt.
Easier to enforce consistent development practices, tools, and configurations across all projects.
## Cons of Monorepos
- As the repository grows, performance can degrade. Large repositories can become unwieldy, slow to clone, and difficult to navigate.
- Operations like merging, rebasing, and history searches can become more complex and time-consuming.
- Fine-grained access control becomes more challenging. It’s harder to restrict access to specific parts of the codebase when everything is in a single repository.
## Use Cases for Monorepos
**1. Large-Scale Applications**
Organisations developing large-scale applications with multiple interconnected components can benefit from monorepos. For example, companies like Google and Facebook use monorepos to manage their extensive codebases, enabling seamless integration and deployment.
**2. Microservices Architecture**
In a microservice architecture, where services are designed to be loosely coupled but often need to interact, a monorepo can help maintain consistency and facilitate integration testing. Shared libraries and APIs can be updated and versioned together.
**3. Multi-Platform Development**
When developing applications for multiple platforms (e.g., web, mobile, desktop), a monorepo can centralise shared logic and components, reducing duplication and ensuring consistency across different platform versions.

1,885,293 | HTML layout elements and techniques, HTML responsive web designs, HTML computer code elements | HTML Layout Elements and Techniques HTML Layout Elements HTML has several... | 0 | 2024-06-12T07:39:53 | https://dev.to/wasifali/html-layout-elements-and-techniques-html-responsive-web-designs-html-computer-code-elements-4962 | webdev, css, learning, html | ## **HTML Layout Elements and Techniques**
## **HTML Layout Elements**
HTML has several semantic elements that define the different parts of a web page:
`<header>` - Defines a header for a document or a section
`<nav>` - Defines a set of navigation links
`<section>` - Defines a section in a document
`<article>` - Defines an independent, self-contained content
`<aside>` - Defines content aside from the content (like a sidebar)
`<footer>` - Defines a footer for a document or a section
`<details>` - Defines additional details that the user can open and close on demand
`<summary>` - Defines a heading for the <details> element
## **Example**
```HTML
Cities
London
Paris
Tokyo
London
London is the capital city of England. It is the most populous city in the United Kingdom, with a metropolitan area of over 13 million inhabitants.
Standing on the River Thames, London has been a major settlement for two millennia, its history going back to its founding by the Romans, who named it Londinium.
Footer
```
## **HTML Layout Techniques**
There are four different techniques to create multicolumn layouts. Each technique has its pros and cons:
CSS framework
CSS float property
CSS flexbox
CSS grid
## **CSS Frameworks**
If we want to create your layout fast, you can use a CSS framework, like W3.CSS or Bootstrap.
## **CSS Float Layout**
It is common to do entire web layouts using the CSS float property. Float is easy to learn - we just need to remember how the float and clear properties work.
## **CSS Flexbox Layout**
Use of flexbox ensures that elements behave predictably when the page layout must accommodate different screen sizes and different display devices.
## **CSS Grid Layout**
The CSS Grid Layout Module offers a grid-based layout system, with rows and columns, making it easier to design web pages without having to use floats and positioning.
## **HTML Responsive Web Design**
Responsive web design is about creating web pages that look good on all devices. Responsive Web Design is about using HTML and CSS to automatically resize, hide, shrink, or enlarge, a website, to make it look good on all devices (desktops, tablets, and phones)
## **Setting The Viewport**
To create a responsive website, add the following <meta> tag to all your web pages:
## **Example**
```HTML
<meta name="viewport" content="width=device-width, initial-scale=1.0">
```
## **Responsive Images**
Responsive images are images that scale nicely to fit any browser size.
## **Using the width Property**
If the CSS width property is set to 100%, the image will be responsive
## **Example**
```HTML
<img src="img_girl.jpg" style="width:100%;">
```
## **Using the max-width Property**
If the max-width property is set to 100%, the image will scale down if it has to, but never scale up to be larger than its original size
Show Different Images Depending on Browser Width
The HTML `<picture>` element allows you to define different images for different browser window sizes.
## **Example**
```HTML
<picture>
<source srcset="img_smallflower.jpg" media="(max-width: 600px)">
<source srcset="img_flowers.jpg" media="(max-width: 1500px)">
<source srcset="flowers.jpg">
<img src="img_smallflower.jpg" alt="Flowers">
</picture>
```
## **Responsive Text Size**
The text size can be set with a "vw" unit, which means the "viewport width".
## **Example**
```HTML
<h1 style="font-size:10vw">Hello World</h1>
```
## **HTML Computer Code Elements**
HTML contains several elements for defining user input and computer code.
## **Example**
```HTML
`<code>`
x = 5;
y = 6;
z = x + y;
`</code>`
```
## **HTML `<kbd>` For Keyboard Input**
The HTML `<kbd>` element is used to define keyboard input. The content inside is displayed in the browser's default monospace font.
## **Example**
```HTML
Define some text as keyboard input in a document:
<p>Save the document by pressing <kbd>Ctrl + S</kbd></p>
```
## **HTML `<samp>` For Program Output**
The HTML `<samp>` element is used to define sample output from a computer program. The content inside is displayed in the browser's default monospace font.
## **Example**
Define some text as sample output from a computer program in a document:

After almost 2 weeks I haven't continue my game development journey. either working on my project or continue the course. I have to move to other city, and there is a lot of things to do in life.
But now I will Continue my project. I decided to continue GameDev.tv courses to learn more about Godot instead of working on my project. maybe I will continue my project after finishing this section of the course. and of course I will implement all knowledge and skill I got from the course to my project.
So for the last project in GameDev.tv course, we will try to build a retro FPS game.
## Setting Up the Scene
Create a new project and set up the floor and camera.
As usual, to start project first we need to create new project in Godot and set up the game environment.
## First Person Movement
Using template scripts to quickly get a player character running and jumping.
## Input Events and Aiming
InputEvents and using them to move the camera
Thats all for today, because tomorrow my company held an event, so I need to prepare for that first. *or I will get fired :) | hizrawandwioka |

Subscribe to ‘[Letters to New Coders](https://www.letterstocoders.com/)’ to receive free weekly posts.
As a Computer Science student, I hit a bit of a hiccup while I was working on my first slightly bigger project involving data structures and pointers. It took me a day to write the program, but the program kept crashing.
After spending a few hours debugging, I gave up and decided to rewrite the program.
Spoiler alert: **it was a huge mistake**. Here’s why — and what it taught me about being a good programmer.
## The do-over
Rewriting my program took another day. It wasn’t a huge program, so redoing the effort seemed reasonable. I’d had no luck finding the bug in my first iteration, so I figured that taking the process mindfully from start to finish would help me ensure I had a functional program.
The result? **A different bug.**
This time, the program didn’t crash, but it wasn’t behaving as I expected it to. This was incredibly frustrating. The worst part was that there was now a bug in the part of code that had been working fine before.
For a moment, I considered combining the code from my first and second attempt to create one functional program. But this Frankenstein-approach would require me to understand where the bug was in each program anyway, on top of ensuring two different instances of code worked cohesively together. I’d already exerted duplicate efforts to write a second program, and without a doubt, this approach would only overcomplicate my matter.
The only solution was to go back to debugging my very first attempt, so I did — and eventually I was able to make that first program run perfectly.
While I wasted valuable time rewriting that program, I learned an even more valuable lesson: I should have spent that time debugging instead.
## Don’t start over. Debug.
Debugging can be stressful. It can even be a little disheartening. You can spend hours or days in confusion and frustration, only to find that the bug was under your nose the entire time. But even obvious mistakes like this are commonplace, and there’s no shame in them.
All developers — no matter how experienced — face bugs on a constant basis. So, the sooner you brave the debugging process, the better.
Even still, when you’ve written a relatively small program and get stuck on a bug, your knee-jerk reaction may be to write it from scratch, hoping that you’ll get lucky and come out bug-free.
But there are 2 reasons you shouldn’t do the do-over.
**1) It’s impractical (even unrealistic).**
You simply won’t have the option of rewriting programs as they get bigger. Once you start your first job, you’ll be making changes to big codebases of **millions of lines of code**. You simply don’t have the luxury to rewrite code around bugs when they happen (especially while pressed against deadlines).
Second, and most importantly…
**2) By starting over, you’re not building the muscle of debugging!**
Great developers don’t write perfect code, but they are very skilled at debugging.
Debugging is part and parcel of learning to code. Bugs are simply inevitable. They can arise from various causes, whether they’re your own errors, incompatible codebase changes, or from third-party dependencies. As a result, you can** expect to spend more time debugging** **than writing code** throughout your professional career.
As it turns out, debugging was a significant part of my job at Microsoft, where I focused on debugging process crashes for a few years. I was eventually able to create automations that allowed us to scale this debugging process as we scaled our services. It would’ve been impossible for me to manually debug these crashes on my own once we scaled, but I was only able to automate this process after I gained experience and understood the patterns from years of manual debugging.
The better you get at debugging quickly, the more successful you’ll be. So, work on your debugging skills. It takes time and effort. But whenever you find a bug, you learn a few things.
## 6 trusty tips for debugging
At first, you may hate debugging. But it’s a skill you will strengthen over time. Eventually you’ll agree that there’s no better feeling than finally fixing the bug in your code.
Here are some debugging strategies to explore:
1. **Describe the problem aloud to yourself** (or to a rubber duck, which is what devs call rubber duck debugging). Narrating your thought process can often reveal assumptions you made or details you missed.
2. **Narrow down the area where the bug is occurring.** Being able to “zoom in” on the problem area is like shining a flashlight in the darkness, and seeing exactly where you need to tend your code. It’s the best debugging muscle to develop early-on. You can either do this with a critical review of your code or other strategies like print/log statements.
3. **Use print/log statements.** This involves placing print statements in various points in your program to see where the problem is occurring. For example, you can place four print statements throughout your program. If the program crashes or gives an undesired output between statement 2 and statement 3, you know your bug lies between those particular statements.
4. **Use a debugger.** As a beginner, using a debugging tool can help you while you’re writing small programs in your own environment. Just keep in mind that it’s not a long-term strategy, as most debugging in a professional environment is done after the code is already written, when the only helpful strategy would be using print statements.
5. **Ask for help if you’re stuck.** There’s nothing wrong with asking for help, and the developer community, whether online or through a friend, is often happy to provide feedback.
6. **Sleep on it.** Take a break. You might be code-blind (or concept-blind) after trying to force yourself to figure something out. There’s a huge benefit to walking away from it or sleeping on it, and coming back to it with a fresh mind.
## Mastering the craft
As frustrating as they may be, facing bugs dead-on is always the best approach. You simply can’t learn to code without learning to debug.
This is why I’m really excited about the new course we’ve launched at Educative: [Mastering Debugging: Techniques for Efficient Code Diagnosis](https://www.educative.io/courses/mastering-debugging-techniques-for-eficient-code-diagnosis?utm_campaign=learn_to_code&utm_source=devto&utm_medium=text&utm_content=&utm_term=&eid=5082902844932096).
With this course, you can get hands-on with various types of bugs and debugging strategies, all in a controlled environment. Debugging can be intimidating, but in our AI-powered learning platform, you’ll be able to get feedback and guidance as you build your confidence with concrete debugging skills.
Happy learning!

1,885,291 | Deploy Node App to AWS EC2 Instance. | Deploying a Node.js application on an EC2 instance and configuring a domain to point to it while... | 0 | 2024-06-12T07:33:30 | https://dev.to/spiritmoney/deploy-node-app-to-aws-ec2-instance-1d88 | webdev, devops, beginners, programming | Deploying a Node.js application on an EC2 instance and configuring a domain to point to it while ensuring the app keeps running involves several steps. Here's a comprehensive guide to achieve this:
### Prerequisites
1. AWS Account
2. Domain name
3. Basic knowledge of Node.js, SSH, and Linux command line
### Steps
1. **Launch an EC2 Instance**
- Log in to your AWS Management Console.
- Navigate to the EC2 Dashboard.
- Click "Launch Instance".
- Choose an Amazon Machine Image (AMI), preferably Ubuntu or Amazon Linux.
- Choose an instance type (e.g., t2.micro for small applications).
- Configure instance details, storage, and tags as needed.
- Configure Security Group to allow HTTP (port 80), HTTPS (port 443), and SSH (port 22) access.
- Review and launch the instance, then download the key pair for SSH access.
2. **Set Up the EC2 Instance**
- Connect to your EC2 instance via SSH:
```
ssh -i /path/to/your-key-pair.pem ubuntu@your-ec2-public-ip
```
- Update the package list and install the necessary dependencies:
```
sudo apt update
sudo apt install nodejs npm
sudo npm install -g pm2
```
3. **Deploy Your Node.js Application**
- Transfer your application code to the EC2 instance using `scp` or by cloning from a Git repository:
```
scp -i /path/to/your-key-pair.pem -r /local/path/to/your-app ubuntu@your-ec2-public-ip:/home/ubuntu
```
- Navigate to your application directory and install dependencies:
```
cd /home/ubuntu/your-app
npm install
```
- Start your Node.js application using PM2 to keep it running:
```
pm2 start app.js
pm2 save
pm2 startup
```
4. **Set Up a Domain Name**
- Go to your domain registrar and configure the DNS settings:
- Create an `A` record pointing to your EC2 instance's public IP address.
- (Optional) For SSL, consider using AWS Certificate Manager and setting up an Application Load Balancer (ALB).
5. **Configure a Reverse Proxy with Nginx (Optional but Recommended)**
- Install Nginx:
```
sudo apt install nginx
```
- Configure Nginx as a reverse proxy:
```
sudo nano /etc/nginx/sites-available/default
```
- Replace the contents with the following (adjust paths and server name as needed):
```
server {
listen 80;
server_name your-domain.com;
location / {
proxy_pass <http://localhost:3000>;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
```
- Test the Nginx configuration and restart Nginx:
```
sudo nginx -t
sudo systemctl restart nginx
```
6. **Access Your Application**
- Navigate to your domain in a web browser to see your deployed Node.js application.
### Additional Tips
- **Security:** Regularly update your EC2 instance and installed packages.
- **Monitoring:** Use PM2's monitoring tools to keep track of your application's performance.
- **Backups:** Consider setting up automatic backups of your EC2 instance and application data.
This guide provides a basic setup. For production environments, you may want to look into more advanced configurations, such as load balancing, auto-scaling, and using a managed database service like Amazon RDS. | spiritmoney |

Michel was introduced to football at the age of six, when his father took him to watch a match between local Lorraine club Metz and a star team that included former Barcelona player Ladislav Kubala. During the match, Kubala made an impressive no-look pass, prompting young Michel to ask his father how it was possible. Aldo's explanation, "He looked ahead," left a lasting impression on Michel and shaped his football philosophy.
[DEV](https://michel-platini.com/)
At age nine, Michel played his first official match, which ended in a resounding 9–0 victory for his team, with Michel scoring two goals despite only joining the match towards the end. This first display of talent paved the way for his future career. In September 1966, he began playing for his local club Joeuf, where he trained tirelessly. Despite being the smallest among his peers and earning the nickname Shorty, Michel's determination never wavered. His peers soon gave him more flattering nicknames, such as The Little Prince of Football or Peleatini, a playful combination of his name with that of the legendary Brazilian player Pelé. | borolo_hok_f3bdd1c0cdce40 |

The traditional Relative Strength Index (RSI) uses two lines to reflect the strength of the price trend. This kind of graph can provide investors with an operation basis, which is very suitable for short-term price difference operations.
Based on the principle of balance between supply and demand in the market, RSI judges the strength of the buying and selling power of the long and short sides of the market by comparing the price rise and fall in the past period, and thus judges the future market trend.
## The role of RSI
In actual trading, RSI is generally only used as a reference to judge the price trend, and it is difficult to issue accurate trading signals by itself. It is just a supporting evidence supplemented by other technical analysis. For example, in the k line form theory, when the head and shoulders top pattern is confirmed, if the RSI is in the overbought zone at this time, the possibility of reversal is further strengthened.
The mathematical principle is that, in simple terms, the power comparison between buyers and sellers is obtained by numerical calculation. For example, if 100 people face a product, if more than 50 people want to buy, and they are competing to raise prices, the price of the product will rise. On the contrary, if more than 50 people are competing to sell, the price will naturally fall.
## Definition of RSI
First define the rising range U and falling range D:
Then define the relative strength
Among them, SMA (x, n) is the simple moving average of x with period n.
After normalizing RS, we get RSI:
After normalization, the value range of RSI is guaranteed to be between 0 and 100, which makes the RSI at different times comparable. It can be seen from the definition that RSI is positively related to RS, and RS is directly proportional to the average increase in the past n cycles and inversely proportional to the average decrease in the past n cycles.
Therefore, the RSI measures the magnitude of the average increase in the past n cycles relative to the average decline, that is, the strength of the bulls relative to the bears in the past n cycles. The larger the value, the stronger the bulls in the past period; the smaller the value, the stronger the bulls in the past.
## RSI strategy
The traditional RSI timing strategy is mainly divided into two categories. One type is a reversal strategy, that is, when the RSI is greater than (less than) a larger (smaller) value, the situation in which the power of buying parties (selling parties) is dominant will change.
The other type of strategy is just the opposite, that is, when the RSI changes from small to large (from large to small), it indicates that the buying parties (selling parties) power is dominant, and that this trend will continue. The following is a detailed introduction.
### RSI reversal strategy:
If the upper threshold of RSI is M, the lower threshold is 100-M. The area where M < RSI < 100 is defined as the over-buying area, that is, at this time, buying parties have been rising for a period of time in the past, and then the probability of the selling side prevailing is greater; otherwise, the area where 0 < RSI < 100-M is defined as over-selling area, at this time, the selling side has pressed the price for a period of time, after which the probability of buying parties prevailing is greater.
Therefore, when RSI > M, the position is closed and shorted, and when RSI < 100-M, the position is closed and longed, as shown in the figure below. Generally, the value of M is 80 or 70.
### RSI Trend Strategy:
The RSI trend strategy is similar to the moving average trend strategy. When the short-term RSI cross up (down) the long-term RSI, it is considered that buying parties (selling parties) have begun to push, and the trend of price increases (decreases) will continue for a period of time. A short-term RSI cross up the long-term RSI is called a golden cross, which is the buying opportunity; a short-term RSI cross down a long-term RSI is called a death cross, which is a selling opportunity, as shown in the following figure.
## Traditional RSI timing strategy for stock index futures
how effective is RSI in quantitative trading? Let's test the traditional RSI timing strategy on IF300. In order to highlight the essence, we adopted the simplest RSI timing strategy without setting take-profit and stop-loss.
Code:
```
/*backtest
start: 2015-02-22 00:00:00
end: 2020-04-09 00:00:00
period: 1d
exchanges: [{"eid":"Futures_CTP","currency":"FUTURES"}]
*/
function main() {
$.CTA('IF000', function (st) {
var r = st.records;
if (r.length < 14) {
return;
}
var rsi = talib.RSI(r, 14);
var rsi1 = rsi[rsi.length - 2];
var mp = st.position.amount;
if (mp != 1 && rsi1 < N) {
return 1;
}
if (mp != -1 && rsi1 > 100 - N) {
return -1;
}
});
}
```
Backtest results
It can be seen that whether it is used in the short-term or long-term, the return of the RSI reversal strategy is negative. Traditional RSI reversal strategies cannot be used directly for quantitative trading alone.
## Strategy drawbacks
So is there a better RSI timing strategy for stock index futures or commodity futures? We start with the shortcomings of traditional RSI timing strategies. The disadvantage of the traditional RSI reversal strategy is that it only uses the RSI indicator of a single period. Although the short-term RSI is in the over-selling zone, the RSI may be in the over-buying zone in the long-term. At this time, short selling can only make little profit in the short-term, and it is likely to lose money in the longer-term.
The traditional RSI trend strategy is the lag of crossover, which often occurs after a period of rise. At this time, there is not much time until the next reversal, so the profit margin is small. At the same time, the crossover only considers the relative size of the long and short periods of RSI, and does not consider the absolute size of the RSI itself. Therefore, by combining the advantages of the two traditional strategies, a new long-term and short-term RSI timing strategy can be obtained.
## Strategy upgrade
In order to overcome the disadvantages of using a single RSI, we use the same parameter period N on two K lines with different periods to calculate the short-term and long-term RSI respectively. In this way, it can better reflect the strength of long and short power in the medium and long term.
In order to overcome the shortcomings of using RSI relative size, we set two thresholds L and S for long-term and short-term RSI respectively. When the long-term RSI > L, the long-term perspective is considered to be dominant, and when the short-term RSI > S, the long-party is beginning to push, and the trend will continue; and vice versa.
Therefore, first of all, we can have a prediction on the trend range of L and S. Since short-term RSI is more sensitive than long-term RSI, L < S. The value range of L should be around 50, and the trend range of S should be around 80. In this way, the screening effect of long-term RSI can be guaranteed.
## Strategy logic
- Long position condition: long-term RSI> L, and short-term RSI> S.
- Short-term conditions: long-term RSI < 100-L, and short-term RSI < 100-S.
- Closing position conditions: Floating profit and loss reach a certain level, or the time is equal to 5 minutes before market close.
The improved RSI trading strategy separately calculates the RSI indicators on the K line of different periods. When the RSI of the low frequency K line is strong and the RSI of the high frequency K line is very strong, buying long; when the RSI of the low frequency K line is weak, the high frequency K line RSI indicator is weak, selling short; and also close all positions before market close.

This means marketing efforts must be tailored to address the specific needs, pain points, and buying behaviors of businesses, which often involve longer sales cycles and multiple decision-makers.
## Key Strategies for B2B SaaS Marketing Success
1. Targeted Customer Segmentation: Start by identifying your ideal customer profiles (ICPs) based on factors such as industry, company size, and pain points. Segment your target audience accordingly and tailor your marketing messages to address the specific needs of each segment.
2. Educational Content Marketing: B2B buyers are often looking for solutions to specific challenges they face in their industries. Create high-quality, educational content such as blog posts, whitepapers, case studies, and webinars that provide valuable insights and solutions to these challenges. Position your SaaS product as the answer to their problems.
3. Thought Leadership and Authority Building: Establish your company as a thought leader in your industry by sharing expertise through thought-provoking content, industry reports, and speaking engagements. Position your executives and key team members as industry experts who can provide valuable insights and guidance.
4. Strategic SEO and Content Optimization: Optimize your website and content for search engines to improve visibility and attract organic traffic. Conduct keyword research to identify relevant search terms and incorporate them naturally into your content. Focus on creating comprehensive, in-depth content that provides value to your target audience.
5. Inbound Marketing and Lead Generation: Implement an inbound marketing strategy focused on attracting and nurturing leads through relevant content, email marketing, and social media engagement. Offer valuable resources such as eBooks, templates, and toolkits in exchange for contact information to build your email list and nurture leads through the sales funnel.
6. Account-Based Marketing (ABM): For B2B SaaS companies targeting high-value accounts, ABM can be a highly effective strategy. Identify key accounts that align with your ICPs and create personalized marketing campaigns tailored to each account's specific needs and pain points. Leverage personalized outreach, targeted advertising, and account-specific content to engage decision-makers within these accounts.
7. Customer Success and Retention Strategies: In the B2B SaaS space, customer retention is just as important as customer acquisition. Implement proactive customer success strategies to ensure that your customers derive maximum value from your product. Offer ongoing support, training, and resources to help them achieve their goals. Encourage customer feedback and use it to continuously improve your product and services.

1,885,270 | The Rise of FRP Columns in Modern Construction | In recent years, the construction industry has witnessed significant advancements in materials and... | 0 | 2024-06-12T07:20:36 | https://dev.to/mark_anderson_6be2c05bc05/the-rise-of-frp-columns-in-modern-construction-5bi1 | architecture, architecturalproducts | In recent years, the construction industry has witnessed significant advancements in materials and technologies, one of which is the introduction of Fiber Reinforced Polymer (FRP) columns. FRP columns are rapidly gaining popularity due to their exceptional properties and versatile applications. This article explores the benefits, applications, and future potential of FRP columns, highlighting why they are becoming a preferred choice in modern construction.
**Understanding FRP Columns**
FRP, or Fiber Reinforced Polymer, is a composite material made from a polymer matrix reinforced with fibers. These fibers can be made from glass (GFRP), carbon (CFRP), aramid (AFRP), or basalt (BFRP). The combination of these materials results in a highly durable and flexible product that can withstand various environmental conditions and loads.
**The Advantages of FRP Columns**
**Lightweight and High Strength**
**Lightweight:** One of the most notable advantages of [frp columns structural](https://meltonclassics.com/products/architectural-columns/fiberglass-columns-covers/designs/) is their lightweight nature. They weigh significantly less than traditional materials like steel or concrete, which reduces the overall load on the structure. This aspect is particularly beneficial in retrofitting projects where weight addition needs to be minimal.
High Strength: Despite their lightweight nature, FRP columns possess a high strength-to-weight ratio. This means they can bear substantial loads without compromising structural integrity.
Corrosion Resistance
Unlike traditional materials, FRP columns are highly resistant to corrosion. This makes them ideal for use in environments exposed to moisture, chemicals, or saltwater, such as coastal regions or industrial sites.
**Durability and Longevity**
FRP columns are known for their long lifespan. They do not degrade or lose strength over time, even when exposed to harsh environmental conditions. This durability translates into reduced maintenance costs and a longer service life for structures.
**Ease of Installation**
The lightweight nature of FRP columns makes them easier and faster to install compared to traditional materials. This can significantly reduce construction time and labor costs.
**Design Flexibility**
FRP columns can be manufactured in various shapes, sizes, and colors, offering architects and engineers greater design flexibility. They can be molded into complex shapes and customized to meet specific aesthetic and structural requirements.
**Environmental Benefits**
FRP columns are an environmentally friendly choice as they can be made from recyclable materials. Additionally, their long lifespan reduces the need for frequent replacements, leading to less waste.
Applications of FRP Columns
**Infrastructure Projects**
FRP columns are widely used in infrastructure projects such as bridges, highways, and tunnels. Their corrosion resistance and durability make them ideal for these applications, where they are exposed to harsh environmental conditions.
**Commercial Buildings**
In commercial construction, FRP columns are used for both structural and decorative purposes. They provide support while enhancing the aesthetic appeal of buildings.
**Industrial Facilities**
Industrial environments often expose structures to chemicals and extreme conditions. FRP columns, with their resistance to corrosion and chemicals, are perfect for such settings, ensuring the longevity of the facility.
**Marine Structures**
Marine structures like docks, piers, and seawalls benefit greatly from the use of FRP columns. The material's resistance to saltwater corrosion ensures these structures remain robust and durable over time.
Retrofitting and Rehabilitation
FRP columns are also used in the retrofitting and rehabilitation of existing structures. Their lightweight nature makes them suitable for strengthening buildings and bridges without adding significant weight.
**Residential Buildings**
While not as common as in commercial or industrial applications, FRP columns are also finding their way into residential construction, particularly in custom homes that require unique design elements.
Case Studies
**The Sunshine Skyway Bridge**
Located in Florida, the Sunshine Skyway Bridge is an iconic example of FRP usage in infrastructure. The bridge employs FRP columns to support its structure, providing resistance to the corrosive saltwater environment and ensuring a longer lifespan.
**The Ohio River Bridges Projec**t
The Ohio River Bridges Project is another notable case where FRP columns were used. The project involved constructing new bridges and rehabilitating existing ones. The use of FRP columns helped in enhancing the structural integrity and extending the service life of the bridges.
**Retrofitting of Heritage Buildings in Europe**
Several heritage buildings in Europe have been retrofitted using FRP columns. These projects demonstrate the material's ability to provide structural reinforcement while preserving the architectural integrity of historic structures.
**Future Prospects of FRP Columns**
As the construction industry continues to evolve, the demand for sustainable and efficient materials is expected to rise. FRP columns, with their myriad of benefits, are well-positioned to meet this demand. Future advancements in FRP technology could further enhance their properties, making them even more integral to construction projects.
**Technological Advancements**
Ongoing research and development in FRP technology are likely to yield materials with even greater strength, durability, and environmental resistance. Innovations in manufacturing processes could also make FRP columns more cost-effective.
**Increased Adoption in Green Building Practices**
With a growing emphasis on sustainable construction, FRP columns are likely to see increased adoption. Their recyclability and long lifespan align with the principles of green building, making them a preferred choice for eco-conscious projects.
**Integration with Smart Technologies**
The integration of smart technologies with FRP columns could lead to the development of intelligent structures. Embedding sensors within FRP columns can enable real-time monitoring of structural health, providing valuable data for maintenance and safety purposes.
**Expansion into New Markets**
As awareness of the benefits of [Melton Classics](https://meltonclassics.com/
) FRP columns grows, they are expected to expand into new markets and applications. This could include more widespread use in residential construction and emerging industries such as renewable energy.
**Conclusion**
FRP columns are revolutionizing the construction industry with their unique combination of strength, durability, and versatility. Their numerous advantages over traditional materials make them an excellent choice for a wide range of applications, from infrastructure projects to commercial and industrial buildings. As technology advances and the demand for sustainable construction materials increases, FRP columns are poised to play a pivotal role in shaping the future of modern construction. Whether used for new builds or retrofitting existing structures, FRP columns offer a durable, cost-effective, and environmentally friendly solution that meets the needs of today's builders and architects.

1,881,841 | Back2Basics: Setting Up an Amazon EKS Cluster | Overview This blog post kicks off a three-part series exploring Amazon Elastic Kubernetes... | 27,819 | 2024-06-12T07:19:27 | https://dev.to/aws-builders/back2basics-setting-up-an-amazon-eks-cluster-2ep1 | aws, eks, kubernetes, opentofu | ### Overview
This blog post kicks off a three-part series exploring Amazon Elastic Kubernetes Service (EKS) and how builders like ourselves can deploy workloads and harness the power of Kubernetes.
Throughout this series, we'll delve into the fundamentals of Amazon EKS. We'll walk through the process of cluster provisioning, workload deployment, and monitoring. We'll leverage various solutions along the way, including `Karpenter` and `Grafana`.
As mentioned, this series aims to empower fellow builders to explore the exciting world of containerization.
### Kubernetes And It's Components
Before we dive into provisioning our first cluster, let's take a quick look at Kubernetes and its components.
**Control Plane Components**
- `kube-apiserver` - the central API endpoint for Kubernetes, handling requests for cluster management.
- `etcd` - a consistent and highly-available key value store used as Kubernetes' backing store for all cluster data.
- `kube-scheduler` - the automated scheduler responsible for assigning pods to available nodes in the cluster.
- `kube-controller-manager` - component that runs controller processes (e.g. Node controller, Job controller, etc.)
- `cloud-controller-manager` - component that embeds cloud-specific control logic.
**Node Components**
- `kubelet` - an agent that runs on each node in the cluster that makes sure that containers are running in a Pod.
- `kube-proxy` - is a network proxy that runs on each node in the cluster, implementing part of the Kubernetes service concept.
- `Container runtime` - is responsible for managing the execution and lifecycle of containers within Kubernetes.
That's a quick recap of Kubernetes components. We will talk more about the different things that make up Kubernetes, like pods and services, later on in this series.
_Worth noting – this month marks a significant milestone! June 2024 marks the 10th anniversary of Kubernetes🥳🎂. Over the past decade, it has established itself as the go-to platform for container orchestration. This widespread adoption is evident in its integration with major cloud providers like AWS._
### Amazon Elastic Kubernetes Service (EKS)
> Amazon Elastic Kubernetes Service (Amazon EKS) is a managed Kubernetes service to run Kubernetes in the AWS cloud and on-premises data centers. In the cloud, Amazon EKS automatically manages the availability and scalability of the Kubernetes control plane nodes responsible for scheduling containers, managing application availability, storing cluster data, and other key tasks. Read more: https://aws.amazon.com/eks/
There are several ways to provision an EKS cluster in AWS:
1. **AWS Management Console** - provides a user-friendly interface for creating and managing clusters.
2. **Using `eksctl`** - a simple command-line tool for creating and managing clusters on EKS.
3. **Infrastructure as Code (IaC) tools** - tools like `CloudFormation`, `Terraform` and `OpenTofu`.
In this series will use `OpenTofu` to provision an EKS cluster along with all the necessary resources to create a platform ready for workload deployment. So if you already know `Terraform`, learning `OpenTofu` will be easy as it is an open-source, community-driven fork of `Terraform` managed by the Linux Foundation. It offers similar functionalities while being actively developed and maintained by the open-source community.
### Let's Get Our Hands Dirty!
Our first goal is to setup a cluster. For this activity, we will be using this repository: {% embed https://github.com/romarcablao/back2basics-working-with-amazon-eks %}
**Prerequisite**
Make sure you have `OpenTofu` installed. If not, head over to the [OpenTofu Docs](https://opentofu.org/docs/intro/install/) for a quick installation guide.
**Steps**
**1. Clone the repository**
First things first, let's grab a copy of the code:
```bash
git clone https://github.com/romarcablao/back2basics-working-with-amazon-eks.git
```
**2. Configure `terraform.tfvars`**
Modify the `terraform.tfvars` depending on your need. As of now, it is set to use Kubernetes version 1.30 (the latest at the time of writing), but feel free to adjust this and the region based on your needs. Here's what you might want to change:
```yaml
environment = "demo"
cluster_name = "awscb-cluster"
cluster_version = "1.30"
region = "ap-southeast-1"
vpc_cidr = "10.0.0.0/16"
```
**3. Initialize and install plugins (tofu init)**
Once you've made your customizations, run `tofu init` to get everything set up and install any necessary plugins.
**4. Preview the changes (tofu plan)**
Before applying anything, let's see what OpenTofu is about to do with `tofu plan`. This will give you a preview of the changes that will be made.
**5. Apply the changes (tofu apply)**
Run `tofu apply` and when prompted, type `yes` to confirm the changes.
Looks familiar? You're not wrong! `OpenTofu` works very similarly as it shares a similar core setup with `Terraform`. And if you ever need to tear down the resources, just run `tofu destroy`.
**Now, lets check the resources provisioned!**
Once provisioning is done, we should be able to see a new cluster. But where can we find it? You can simply use the search box in `AWS Management Console`.
Click the cluster and you should be able to see something like this:
Do note that we enable a couple of addons in the template hence we should be able to see these three core addons.
`CoreDNS` - this enable service discovery within the cluster.
`Amazon VPC CNI` - this enable pod networking within the cluster.
`Amazon EKS Pod Identity Agent` - an agent used for EKS Pod Identity to grant AWS IAM permissions to pods through Kubernetes service accounts.
### Accessing the Cluster
Now that we have the cluster up and running, the next step is to check resources and manage them using `kubectl`.
By default, the cluster creator has full access to the cluster. First, we need to fetch the`kubeconfig` file by running:
```bash
aws eks update-kubeconfig --region $REGION --name $CLUSTER_NAME
```
Now, let's list all pods in all namespaces
```bash
kubectl get pods -A
```
Here's a sample output from the command above:
```bash
NAMESPACE NAME READY STATUS RESTARTS AGE
kube-system aws-node-5kvd4 2/2 Running 0 2m49s
kube-system aws-node-n2dqb 2/2 Running 0 2m51s
kube-system coredns-5765b87748-l4mj5 1/1 Running 0 2m7s
kube-system coredns-5765b87748-tpfnx 1/1 Running 0 2m7s
kube-system eks-pod-identity-agent-f9hhb 1/1 Running 0 2m7s
kube-system eks-pod-identity-agent-rdbzs 1/1 Running 0 2m7s
kube-system kube-proxy-8khgq 1/1 Running 0 2m51s
kube-system kube-proxy-p94w7 1/1 Running 0 2m49s
```
Let's check a couple of objects and resources:
```bash
# List all deployments in kube-system
kubectl get deployment -n kube-system
# List all daemonsets in kube-system
kubectl get daemonset -n kube-system
# List all nodes
kubectl get nodes
```
How about deploying a simple workload?
```bash
# Create a deployment
kubectl create deployment my-app --image nginx
# Scale the replicas of my-app deployment
kubectl scale deployment/my-app --replicas 2
# Check the pods
kubectl get pods
# Delete the deployment
kubectl delete deployment my-app
```
### What's Next?
Yay🎉, we're able to provision an EKS cluster, check resources and objects using `kubectl` and create a simple nginx deployment. Stay tuned for the next part in this series, where we'll dive into deployment, scaling and monitoring of workloads in Amazon EKS!
