1,915,195 | Taming the Wild West: Leveraging Volatility for Profit in Crypto Trading | The cryptocurrency market, with its characteristic price swings, presents a unique challenge for... | 0 | 2024-07-08T04:18:39 | https://dev.to/epakconsultant/taming-the-wild-west-leveraging-volatility-for-profit-in-crypto-trading-4d4p | trading | The cryptocurrency market, with its characteristic price swings, presents a unique challenge for traders. While volatility can be daunting, it also offers fertile ground for profit. This article explores strategies for navigating volatile crypto markets, calculating risk/reward ratios, using leverage cautiously, and implementing robust risk management techniques.
Embracing the Rollercoaster: Strategies for Volatile Markets
- Trend Following: Identify and capitalize on established uptrends or downtrends. Use technical indicators like moving averages or breakout patterns to confirm trends and enter positions aligned with the prevailing direction.
- Mean Reversion: Look for opportunities to buy assets that have dipped below their average price (oversold) and sell assets that have surged above their average (overbought). Indicators like RSI (Relative Strength Index) can help identify these conditions.
- Range Trading: Profit from price movements within a defined trading range. Identify support and resistance levels using technical analysis and enter positions near these levels, aiming to buy near support and sell near resistance.
Pro Tip: Don't chase every trade. Focus on high-probability setups that align with your chosen strategy and risk tolerance.
Calculating Risk vs. Reward: Volatility's Balancing Act
Before entering a trade, calculate the potential risk and reward to determine if the trade aligns with your financial goals. Here's how:
- Reward: Estimate the potential profit by calculating the difference between your entry price and your target exit price (take profit level).
- Risk: Determine the maximum amount you're willing to lose on the trade. This is typically set using a stop-loss order, which automatically exits your position if the price reaches a predetermined level.
[Crypto Conquest: Mastering Market Mechanics for Profitable Trading](https://www.amazon.com/dp/B0CW1HL6SM)
Volatility Impact: In a volatile market, set tighter stop-loss levels to limit potential losses. However, this may also limit potential profits on winning trades.
Remember: Always aim for a favorable risk/reward ratio, ideally targeting profits that are at least twice the potential risk.
Leverage: A Double-Edged Sword for Amplifying Gains (and Losses)
Leverage allows you to control a larger position size than your initial capital by borrowing funds from a trading platform. This can magnify your profits if the market moves in your favor. However, it also amplifies losses if the market goes against you.
Using Leverage Responsibly in Volatile Markets:
- Start Small: Begin with a low leverage ratio (e.g., 2x or 5x) to gain experience managing leveraged positions before venturing into higher leverage.
- Focus on Short-Term Trades: Volatility can reverse quickly. Use leverage primarily for short-term trades where you can exit your position swiftly if needed.
- Maintain a Healthy Margin: Keep a sufficient amount of capital in your account to maintain your margin requirements. A falling asset price can trigger a margin call, forcing you to liquidate your position at a loss.
Remember: Leverage is a risky tool. Only use it if you fully understand the risks involved and have a robust risk management strategy in place.
Managing Risk Through Position Sizing and Stop Losses
- Position Sizing: Control your risk exposure by allocating a small percentage (e.g., 1-2%) of your total capital to each trade. This prevents a single losing trade from wiping out your entire account.
- Stop-Loss Orders: Set stop-loss orders at a predefined distance from your entry price to automatically exit your position if the price moves against you. This helps limit potential losses, especially in volatile markets.
- Trailing Stop-Loss: Consider using trailing stop-loss orders, which automatically adjust your stop-loss level as the price moves in your favor, locking in profits while still allowing for some price fluctuations.
Remember: Risk management is paramount in any trading strategy, but even more so in volatile markets like crypto. By employing these techniques, you can minimize potential losses and protect your capital.
The crypto market, with its inherent volatility, can be a lucrative arena for skilled traders. By understanding strategies for navigating volatility, calculating risk/reward ratios, utilizing leverage cautiously, and implementing effective risk management techniques, you can position yourself to profit from the market's dynamic nature. However, always remember to prioritize risk management and never invest more than you can afford to lose. | epakconsultant |
1,915,196 | Building Reusable List Components in React | Introduction In React development, it's common to encounter scenarios where you need to... | 0 | 2024-07-08T04:23:03 | https://dev.to/vyan/building-reusable-list-components-in-react-8bf | javascript, react, beginners, webdev | ## Introduction
In React development, it's common to encounter scenarios where you need to display lists of similar components with varying styles or content. For instance, you might have a list of authors, each with different information like name, age, country, and books authored. To efficiently handle such cases, we can leverage React's component composition and props passing. In this blog post, we will explore how to build reusable list components in React to achieve this.
## Defining the Data
Let's consider a scenario where we have an array of authors, each represented by an object containing their details like name, age, country, and books they've written. We want to create two distinct styles for displaying these authors: a large card displaying all details including their books, and a smaller card with just the name and age.
Firstly, we define our array of authors:
```javascript
export const authors = [
{
name: "Sarah Waters",
age: 55,
country: "United Kingdom",
books: ["Fingersmith", "The Night Watch"],
},
{
name: "Haruki Murakami",
age: 71,
country: "Japan",
books: ["Norwegian Wood", "Kafka on the Shore"],
},
{
name: "Chimamanda Ngozi Adichie",
age: 43,
country: "Nigeria",
books: ["Half of a Yellow Sun", "Americanah"],
},
];
```
## Creating List Item Components
Next, we create our two different styles of author list items: `LargeAuthorListItem` and `SmallAuthorListItem`. The former displays all details including books, while the latter only shows name and age.
### Large Author List Item
```javascript
export const LargeAuthorListItem = ({ author }) => {
const { name, age, country, books } = author;
return (
<>
<h2>{name}</h2>
<p>Age: {age}</p>
<p>Country: {country}</p>
<p>
Books:{" "}
{books.map((book, index) => (
<span key={index}>{book}</span>
))}
</p>
</>
);
};
```
### Small Author List Item
```javascript
export const SmallAuthorListItem = ({ author }) => {
const { name, age } = author;
return (
<>
<h2>{name}</h2>
<p>Age: {age}</p>
</>
);
};
```
## Creating a Reusable List Component
Now, to make these components reusable and versatile, we create a `RegularList` component. This component takes in an array of items, a prop specifying the source of data (in our case, "author"), and the type of item component to render.
```javascript
export const RegularList = ({ items, sourceName, ItemComponent }) => {
return (
<>
{items.map((item, index) => (
<ItemComponent key={index} {...{ [sourceName]: item }} />
))}
</>
);
};
```
## Using the Reusable List Component
With `RegularList`, we can easily render lists of authors in different styles by passing in the appropriate item component and data source name. For example:
```javascript
import { authors, RegularList, LargeAuthorListItem, SmallAuthorListItem } from './components';
const App = () => {
return (
<div>
<h1>Authors</h1>
<h2>Large Cards</h2>
<RegularList items={authors} sourceName="author" ItemComponent={LargeAuthorListItem} />
<h2>Small Cards</h2>
<RegularList items={authors} sourceName="author" ItemComponent={SmallAuthorListItem} />
</div>
);
};
export default App;
```
## Benefits of Reusable Components
By utilizing these components, we can easily create and maintain lists of objects with different styles across our application. This approach promotes code reusability and maintainability, making our React application more efficient and scalable.
### Code Reusability
Creating reusable components reduces code duplication and ensures consistency across the application. Changes made to a single component will automatically reflect wherever it is used.
### Maintainability
With a clear separation of concerns, components are easier to manage and update. This modular approach makes the codebase cleaner and more organized.
### Efficiency
Reusable components can improve performance by reducing the need for redundant code execution. This makes the application more efficient and responsive.
## Conclusion
Building reusable list components in React is a powerful technique that can simplify your development process and enhance the maintainability of your codebase. By leveraging component composition and props passing, you can create versatile components that adapt to different styles and content requirements. Give this approach a try in your next React project and experience the benefits of reusable components!

1,915,197 | Serverless: An Evolving Architecture, Not Just a Runtime | "The reports of my death have been greatly exaggerated." - Mark Twain This famous quote applies... | 14,747 | 2024-07-08T04:24:09 | https://www.internetkatta.com/serverless-an-evolving-architecture-not-just-a-runtime | serverless, aws, architecture, devops | > "The reports of my death have been greatly exaggerated." - Mark Twain
This famous quote applies just as well to technology as it does to people. In the fast-paced world of software development, we often hear proclamations about the death of one technology or another. But the truth is, technologies rarely die outright - they evolve, transform, and find new niches.
Take serverless computing, for instance. When it first emerged, some viewed it as merely a new runtime environment. But as the concept has matured, it's become clear that serverless represents something much more profound: a shift in how we architect and think about applications.
I am writing this blog to express my views about Serverless. I believe that every technological evolution happens to solve a problem or meet a specific need. I am always amazed by people who write or create content around the idea that "This technology is dead." I have been in the software development career for the past 13 years and have seen the evolution from VB to [VB.NET](http://VB.NET), ASP to [ASP.NET](http://ASP.NET), PHP, Python, Java, CSS to SCSS, HTML to Web3, and many more technological advancements. To be frank and realistic, even if we move from one point to another, the older point is still valid for certain use cases. They never die; they evolve with the demand. There's no one-size-fits-all solution; the perfect choice depends on the project. Currently, everyone wants to ride the wave of AI and Generative AI, but in reality, many people still haven't found the right use case for it. It can't be fitted everywhere, or maybe something different will come along that fits better. Serverless is the same. Serverless came into the picture almost immediately after the cloud era started because of the need for a situation where developers were more in number, and managing or scaling servers was painful or not easy to do.
To understand why serverless computing emerged as a solution, let's explore the specific challenges it was designed to address.
## The Birth of Serverless
To understand serverless, we need to look at the problems it was born to solve.
### Focus on code, not servers
As a developer who understands the challenges developers face, I can explain this better. I am a big fan of the cloud era and a dedicated full-stack developer. When the cloud era began, dedicated cloud operations or DevOps were not as popular as they are today. Now, Cloud Ops and DevOps are crucial parts of an application team. Back then, developers had to take on the challenge of creating, managing, and scaling servers based on thresholds. This required both time and effort, diverting them from their primary role as developers. Although I personally enjoyed that work, companies couldn't afford to invest that much time and effort.
Enter serverless, promising to abstract away infrastructure concerns and allow developers to focus solely on writing code. Beyond simplifying development, serverless also brought significant cost benefits.
### Cost efficiency:
Along with this, customers started complaining about getting huge bills without making much profit in their business. Cost was a major factor! They were paying for resources that weren't fully utilized and not getting any business value out of it. That's when the "Pay-per-use model" emerged with Serverless, and it was a game-changer! In addition to cost savings, serverless computing also revolutionized scalability.
### Improved scalability:
Scalability existed in traditional infrastructure, but it was a burden on developers. Serverless eliminates the need for developers to provision extra servers in anticipation of spikes or worry about under-provisioning during peak times. Unlike traditional architectures where you might hit a ceiling based on your provisioned servers, serverless can theoretically scale infinitely (though providers may impose some limits). Another critical advantage of serverless is the speed at which developers can deploy applications.
### Faster deployment :
Developers need to provision servers and manage them. All this server management slows down deployments. Developers can't focus on writing code and pushing updates because they're bogged down with infrastructure tasks. They wanted to push code frequently but lacked the time to do so.
## Microservice was perfect match
Microservices emerged from the frustration of dealing with monolithic codebases. The rise of microservices and serverless computing is indeed closely intertwined. That's why I said it was a perfect match! When you're running granular pieces of code, why keep a server running at full capacity? The pay-per-use model was perfect for running microservices. Focus on code, not on servers! Both evolutions shared the same goal: to help developers. That's where the magic happened!
At the same time, frontend frameworks like Angular, NextJS, and React were taking shape, focusing on API-based backends and frontends. This synergy boosted microservices, and microservices, in turn, supercharged serverless!
This synergy was highlighted by the launch of AWS Lambda, which became a key example of serverless computing.
## AWS Lambda = Serverless
So, when the first serverless applications started to get built on AWS, the initial approach was “let’s build microservices”…
The first serverless offerings, like AWS Lambda in 2014, were indeed focused on providing a runtime environment for small, event-driven functions. This led to the initial perception of serverless as simply a new way to run code. Again, it was a perfect match for microservices with the help of Lambda.
Serverless was creating pave to become concept to a way of building and deploying applications where you don't have to manage servers. The cloud provider handles all the infrastructure provisioning, scaling, and maintenance. Same time AWS Lambda was paving foot as function as a service: It's a specific offering from Amazon Web Services (AWS) that allows you to run code in a serverless fashion. You write your code, upload it to Lambda, and define events that trigger the code's execution. Lambda takes care of everything else.
One of my favorite analogies, which I've used in many talks about serverless, is **Ordering pizza is serverless**. Isn't that intriguing? Here's a short video about it.
{% embed https://youtube.com/shorts/J5tCpL4EbYY?feature=share %}
As serverless computing continued to evolve, its potential expanded far beyond initial expectations.
## Evolution of the Serverless Paradigm
As serverless matured, its true potential became apparent. It wasn't just about running functions; it was about reimagining how applications are built, deployed, and scaled. Key developments included:
* **Expansion beyond functions**: Serverless databases, storage, and other managed services emerged, enabling entire applications to be built on serverless principles.
* **Improved developer experience**: Tools and frameworks evolved to make serverless development more accessible and productive.
* **Performance enhancements**: Cold start times decreased, and providers introduced ways to keep functions "warm," addressing early criticisms.
* **Enterprise adoption**: Large organizations began embracing serverless for critical workloads, driving further innovation.
A key aspect of this evolution is the event-driven nature of serverless architectures."
## **Serverless is all about events**
While functions are a core component, events are the lifeblood that triggers those functions and makes everything work together. This statement captures a fundamental characteristic of serverless architectures. At its core, serverless computing is designed to respond to and process events efficiently.
Here's a deeper look at this concept:
### Event-Driven Architecture
Serverless platforms are founded on the principle of event-driven architecture. This means that serverless components are activated by specific events rather than running continuously. It is recommended to bypass the API Gateway whenever possible and use direct event triggers. This approach results in faster and more efficient execution, particularly for internal communication within AWS services. These events can originate from a wide range of sources. :
* HTTP requests (API calls)
* Database changes
* File uploads
* IoT sensor data
* Message queue events
* Scheduled tasks
* Custom application events
### Beyond Functions
While Functions-as-a-Service (FaaS) like AWS Lambda or Azure Functions are often the first thing people think of with serverless, the ecosystem is much broader:
* **Event Streams**: Services like AWS Kinesis or Azure Event Hubs allow for real-time processing of data streams.
* **Notification Services**: AWS SNS or Azure Notification Hubs enable push notifications triggered by events.
* **Message Queues**: Services like AWS SQS or Azure Service Bus decouple components and handle asynchronous processing.
* **Event Buses**: AWS EventBridge or Azure Event Grid route events between decoupled components.
* **Serverless Databases**: DynamoDB streams or Azure Cosmos DB change feed can trigger actions based on data changes.
* **API Gateways**: Managed services that handle API requests and can integrate directly with other serverless components
Understanding the event-driven nature of serverless helps us appreciate its broader architectural implications.
## Serverless: An Evolving Architecture
Today, serverless is best understood not as a specific technology but as an architectural approach emphasizing:
* Event-driven design
* Fine-grained scalability
* Pay-per-use pricing
* Managed services and infrastructure
* Focus on business logic over operational concerns
This shift in thinking has far-reaching implications for how we design, build, and operate software systems.
However, like any technology, serverless computing comes with its own set of challenges.
## Challenges:
* **Vendor Lock-In:** Reliance on a specific cloud provider's serverless platform can make it difficult to switch later.
* **Limited Control:** Developers have less control over the underlying infrastructure compared to traditional deployments.
* **Debugging Challenges:** Debugging serverless applications can be more complex due to their distributed nature.
Despite these challenges, serverless computing exemplifies a broader truth about the persistence and evolution of technology.
## The Persistence of Technology
The evolution of serverless illustrates a broader truth about technology: it rarely dies, but instead transforms and finds new applications. Other examples include:
* **Mainframes**: Once thought obsolete, they remain critical in industries like finance and government.
* **SQL databases**: NoSQL was supposed to kill SQL, but relational databases adapted and remain widely used.
* **Monoliths**: Despite the microservices revolution, monolithic architectures still have their place in certain scenarios.
These examples illustrate that technologies rarely die; they adapt and find new applications. This leads us to an important lesson for developers.
## The Lesson for Developers
As technologists, we should be wary of declaring any technology "dead." Instead, we should focus on understanding the strengths, weaknesses, and appropriate use cases for different approaches. Serverless isn't replacing all other architectures, but it's certainly earned its place in the modern developer's toolkit.
In conclusion, serverless computing demonstrates that true innovation often lies not in creating entirely new technologies, but in reimagining how existing concepts can be applied to solve real-world problems. As we continue to evolve our architectural approaches, let's remember that the most powerful solutions often come from synthesis and adaptation rather than revolution.

For traders seeking to... | 0 | 2024-07-08T04:24:41 | https://dev.to/epakconsultant/unveiling-the-mystery-analyzing-crypto-volatility-with-advanced-charting-tools-4lp2 | trading | The ever-shifting landscape of the crypto market thrives on volatility. For traders seeking to navigate these fluctuations and potentially profit, advanced charting tools become invaluable assets. This article delves into how these tools can be used to visualize volatility, identify patterns, calculate key metrics, and even backtest strategies to optimize trading decisions.
Illuminating Volatility: Candlestick Charts and Technical Indicators
- Candlestick Charts: These visual representations of price action over a specific timeframe form the foundation of technical analysis. The body of the candlestick reflects the opening and closing prices, while the wicks depict the highs and lows. By studying candlestick patterns like hammers, shooting stars, or engulfing patterns, you can glean valuable insights into market sentiment and potential volatility shifts.
- Technical Indicators: These mathematical formulas layered onto price charts help identify trends, overbought/oversold conditions, and potential support and resistance levels. Popular volatility indicators include:
- Bollinger Bands: Visually represent price volatility. Narrowing bands indicate low volatility, while widening bands suggest an increase in volatility.
- Average True Range (ATR): Measures the average price fluctuation of an asset over a chosen period. A rising ATR suggests increasing volatility, while a falling ATR indicates a calmer market.
[Demystifying Attack Graphs: A Beginner's Guide to Building and Verifying Secure Systems](https://www.amazon.com/dp/B0CT94V2LP)
Pro Tip: Combine multiple indicators to gain a more comprehensive understanding of market conditions and potential volatility changes.
Unveiling Volatility's Patterns Across Timeframes
Volatility patterns can emerge across different timeframes on a crypto chart. By analyzing multiple timeframes, you can gain valuable insights into the bigger picture and identify potential trading opportunities.
- Daily Charts: Offer a broad overview of long-term trends and potential major turning points in volatility.
- Hourly Charts: Provide a more detailed picture of intraday volatility swings and potential short-term trading opportunities.
- Lower Timeframes (Minute Charts): Allow for scalping strategies that capitalize on rapid price fluctuations within a short timeframe. However, these can be more susceptible to noise (random price movements).
Remember: Don't get lost in the details. Maintain a balance between analyzing different timeframes to understand the overall market context and identify potential high-probability trades.
Quantifying Volatility: The Power of Metrics
Advanced charting tools allow you to calculate various volatility metrics that provide numerical representations of market fluctuations:
- Average True Range (ATR), as mentioned earlier, helps quantify average price volatility.
- Standard Deviation: Measures the dispersion of price movements from the average price. A higher standard deviation indicates higher volatility.
- Volatility Ratio: Compares the current day's trading range (high minus low) to the average trading range over a chosen period. A ratio above 1 suggests increased volatility compared to the historical average.
Pro Tip: Utilize these metrics in conjunction with other technical analysis tools for a more robust understanding of market conditions.
Backtesting for Strategic Optimization
Backtesting allows you to test your volatility trading strategies on historical data to assess their potential effectiveness. This helps you refine your approach and identify strategies that might perform well in volatile markets.
Here's a simplified backtesting process:
Define Your Strategy: Outline your entry and exit criteria based on volatility indicators or price patterns.
- Choose the Backtesting Tool: Many charting platforms offer built-in backtesting functionalities.
- Select Historical Data: Choose a relevant timeframe of historical crypto price data for your backtesting.
- Run the Backtest: The tool will simulate your trades based on your defined strategy and historical data, providing performance metrics like profitability and win rate.
- Analyze and Refine: Review the backtesting results and adjust your strategy parameters to optimize its effectiveness in volatile markets.
Remember: Backtesting results are based on historical data and don't guarantee future performance. Use them as a guide, not a foolproof prediction tool.
Conclusion: Mastering the Art of Volatility
The ever-changing world of crypto thrives on volatility. By harnessing the power of advanced charting tools, you can gain valuable insights into volatility patterns, calculate key metrics, and even backtest strategies. Remember, a combination of technical analysis, calculated risk management, and a healthy dose of caution can equip you to navigate the dynamic crypto market and potentially profit from its inherent volatility.

description: Learn how to build a functional pastebin service using Python and Flask. This tutorial covers web development basics, file handling, and syntax highlighting.
tags: python,flask
---
In this blog post, we will be building a simple Pastebin service using Python and Flask. Pastebin is a popular web application used to store plain text or code snippets for a certain period of time. We'll create a basic version that allows users to paste text, select the programming language, and get a URL to share the paste. I have also created a YouTube video about this, which you can view [here](https://youtu.be/s2RQfUxOuco).
## Getting Starting
Before begin creating our application lets setup our environment and in order to setup your environment follow these steps:
1. First, Let's create a virtual environment in the project directory.
```shell
python -m venv venv
```
2. Now, once we have created the virtual environment, let's activate it and install all the required libraries that are going to be used by this project.
```shell
pip install Flask shortuuid pygments
```
We'll also use `shortuuid` for generating unique IDs for each paste and `pygments` for syntax highlighting.
3. Now that we have installed all the required libraries, let's create the necessary files and folders.
```shell
mkdir -p pastes templates static && touch index.py templates/index.html static/styles.css
```
This is how your folder structure should look:
```shell
pastebin/
│
├── app.py
├── pastes/
├── templates/
│ └── index.html
└── static/
└── styles.css
```
The `pastes` directory will store the text files for each paste. The templates directory contains our HTML templates, and the static directory contains CSS for styling.
Now that we have set up the environment, it's time to code.
## Writing Code
Let's dive into the code. Create a file named `index.py` and add the following code:
```python
from flask import Flask, request, render_template, abort
import shortuuid
import os
from pygments import highlight
from pygments.lexers import get_lexer_by_name, get_all_lexers
from pygments.formatters import HtmlFormatter
app = Flask(__name__)
# Directory to store paste files
PASTE_DIR = 'pastes'
if not os.path.exists(PASTE_DIR):
os.makedirs(PASTE_DIR)
# Function to get available programming languages for syntax highlighting
def get_language_options():
return sorted([(lexer[1][0], lexer[0]) for lexer in get_all_lexers() if lexer[1]])
# Route for the main page
@app.route('/', methods=['GET', 'POST'])
def index():
if request.method == 'POST':
# Get content and language from the form
content = request.form['content']
language = request.form['language']
# Generate a unique ID for the paste
paste_id = shortuuid.uuid()
# Create the file path for the paste
file_path = os.path.join(PASTE_DIR, paste_id)
# Save the paste content to a file
with open(file_path, 'w') as f:
f.write(f"{language}\n{content}")
# Generate the URL for the new paste
paste_url = request.url_root + paste_id
return render_template('index.html', paste_url=paste_url, languages=get_language_options())
# Render the form with available languages
return render_template('index.html', languages=get_language_options())
# Route to view a specific paste by its ID
@app.route('/<paste_id>')
def view_paste(paste_id):
# Create the file path for the paste
file_path = os.path.join(PASTE_DIR, paste_id)
if not os.path.exists(file_path):
abort(404) # Return a 404 error if the paste does not exist
# Read the paste file
with open(file_path, 'r') as f:
language = f.readline().strip() # First line is the language
content = f.read() # Remaining content is the paste
# Get the appropriate lexer for syntax highlighting
lexer = get_lexer_by_name(language, stripall=True)
# Create a formatter for HTML output
formatter = HtmlFormatter(linenos=True, cssclass="source")
# Highlight the content
highlighted_content = highlight(content, lexer, formatter)
# Get the CSS for the highlighted content
highlight_css = formatter.get_style_defs('.source')
# Render the paste with syntax highlighting
return render_template('index.html', paste_content=highlighted_content, highlight_css=highlight_css)
if __name__ == '__main__':
app.run(debug=True)
```
Once you have created the flask now let's create html template in `templates/index.html` and `style.css` in `static/style.css`
- `templates/index.html`
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Pastebin Service</title>
<link rel="stylesheet" href="{{ url_for(\'static\', filename=\'styles.css\') }}">
{% if highlight_css %}
<style>
{{ highlight_css|safe }}
</style>
{% endif %}
</head>
<body>
<h1>Pastebin Service</h1>
{% if paste_url %}
<p>Your paste URL: <a href="{{ paste_url }}">{{ paste_url }}</a></p>
{% endif %}
{% if paste_content %}
<div class="highlight">
{{ paste_content|safe }}
</div>
{% endif %}
<form method="post">
<textarea name="content" rows="10" cols="50" placeholder="Paste your text here..."></textarea><br>
<select name="language">
{% for code, name in languages %}
<option value="{{ code }}">{{ name }}</option>
{% endfor %}
</select><br>
<button type="submit">Submit</button>
</form>
</body>
</html>
```
- `static/style.css`
```css
body {
font-family: Arial, sans-serif;
margin: 20px;
}
h1 {
color: #333;
}
textarea {
width: 100%;
margin-top: 10px;
}
select, button {
margin-top: 10px;
}
.highlight {
background-color: #f5f5f5;
padding: 10px;
border: 1px solid #ccc;
margin-top: 20px;
}
```
Now that we have created our application, before we run it, let's try to understand how it works by breaking down the code.
### Code Breakdown
1. First, we import the necessary libraries and modules. `Flask` is our web framework, `shortuuid` is used for generating unique IDs, and `Pygments` is for syntax highlighting. We also set up a directory to store our `pastes/`.
```python
from flask import Flask, request, render_template, abort
import shortuuid
import os
from pygments import highlight
from pygments.lexers import get_lexer_by_name, get_all_lexers
from pygments.formatters import HtmlFormatter
app = Flask(__name__)
PASTE_DIR = 'pastes'
if not os.path.exists(PASTE_DIR):
os.makedirs(PASTE_DIR)
```
2. Then we write a function that retrieves all available programming languages supported by Pygments for syntax highlighting and returns them as a sorted list of tuples.
```python
def get_language_options():
return sorted([(lexer[1][0], lexer[0]) for lexer in get_all_lexers() if lexer[1]])
```
3. Then we write the main route for our application. If the request method is POST (i.e., when the user submits a form), it saves the content and language to a new file with a unique ID. The URL for the new paste is generated and displayed to the user. If the request method is GET, it simply renders the form.
```python
@app.route('/', methods=['GET', 'POST'])
def index():
if request.method == 'POST':
content = request.form['content']
language = request.form['language']
paste_id = shortuuid.uuid()
file_path = os.path.join(PASTE_DIR, paste_id)
with open(file_path, 'w') as f:
f.write(f"{language}\n{content}")
paste_url = request.url_root + paste_id
return render_template('index.html', paste_url=paste_url, languages=get_language_options())
return render_template('index.html', languages=get_language_options())
```
This route handles viewing a specific paste. It reads the paste file, applies syntax highlighting using pygments, and renders the highlighted content.
```python
@app.route('/<paste_id>')
def view_paste(paste_id):
file_path = os.path.join(PASTE_DIR, paste_id)
if not os.path.exists(file_path):
abort(404)
with open(file_path, 'r') as f:
language = f.readline().strip()
content = f.read()
lexer = get_lexer_by_name(language, stripall=True)
formatter = HtmlFormatter(linenos=True, cssclass="source")
highlighted_content = highlight(content, lexer, formatter)
highlight_css = formatter.get_style_defs('.source')
return render_template('index.html', paste_content=highlighted_content, highlight_css=highlight_css)
```
Now once we understand how everything works, now you can simply run the application using this command
`python index.py`
## Conclusion
You've built a simple Pastebin service using Python and Flask! This service allows users to paste text, select a programming language, and share the paste via a unique URL. You can expand this project by adding features like expiration times for pastes, user authentication, or even a database to store pastes more efficiently.

It helps developers debug... | 0 | 2024-07-08T04:51:19 | https://dev.to/manojgohel/stop-using-consolelog-and-start-using-this-service-3kfm | console, javascript, webdev, programming | Logging is an essential part of any software development process. It helps developers debug applications, understand workflows, and track down issues. However, relying solely on `console.log` for logging in an Angular application can quickly become problematic, especially when moving from development to production environments.
In this article, I will introduce a logging service that can be easily integrated into your Angular application. This service allows you to control the log level based on the environment configuration, ensuring that verbose logging is available during development but minimized or disabled in production.
# Why You Should Stop Using `console.log`
Using `console.log` statements scattered throughout your codebase can lead to several issues:
1. **Performance Issues**: Excessive logging in production can degrade performance.
2. **Security Risks**: Sensitive information might be logged and exposed.
3. **Clutter**: Logs can quickly become cluttered, making it difficult to find relevant information.
By using a structured logging service, you can mitigate these issues and have more control over what gets logged and when.
# Introducing the Log Service
Here’s a simple but effective logging service for your Angular application. It uses an enumerated log level to control what messages are logged based on the current environment configuration.
# Log Levels Enum
First, we define an enumeration for the different log levels:
```
export enum LogLevel {
info,
error,
warn,
debug,
all,
}
```
# Log Service
Next, we create the `LogService` that utilizes this enum to conditionally log messages:
```
import { Injectable } from "@angular/core";
import { environment } from "../../environments/environment";
import { LogLevel } from "../models/log.interface";
@Injectable({
providedIn: "root",
})
export class LogService {
constructor() {}
log(message?: any, ...optionalParams: any\[\]) {
if (environment.logLevel >= LogLevel.debug) {
console.log(...\[message, ...optionalParams\]);
}
}
table(message?: any, ...optionalParams: any\[\]) {
if (environment.logLevel >= LogLevel.debug) {
console.table(...\[message, ...optionalParams\]);
}
}
trace(message?: any, ...optionalParams: any\[\]) {
if (environment.logLevel >= LogLevel.debug) {
console.trace(...\[message, ...optionalParams\]);
}
}
error(message?: any, ...optionalParams: any\[\]) {
if (environment.logLevel >= LogLevel.error) {
console.error(...\[message, ...optionalParams\]);
}
}
debug(message?: any, ...optionalParams: any\[\]) {
if (environment.logLevel >= LogLevel.debug) {
console.debug(...\[message, ...optionalParams\]);
}
}
info(message?: any, ...optionalParams: any\[\]) {
if (environment.logLevel >= LogLevel.info) {
console.info(...\[message, ...optionalParams\]);
}
}
warn(message?: any, ...optionalParams: any\[\]) {
if (environment.logLevel >= LogLevel.warn) {
console.warn(...\[message, ...optionalParams\]);
}
}
}
```
# Environment Configuration
Finally, we configure the environments to use different log levels:
```
// environment.ts (Development)
export const environment = {
production: false,
logLevel: LogLevel.debug
};
// environment.prod.ts (Production)
export const environment = {
production: true,
logLevel: LogLevel.info
};
```
# How to Use the Log Service
To start using the `LogService`, inject it into your components or services:
```
import { Component, OnInit } from '@angular/core';
import { LogService } from './services/log.service';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: \['./app.component.css'\]
})
export class AppComponent implements OnInit {
constructor(private logService: LogService) {}
ngOnInit() {
this.logService.info('Application initialized');
this.logService.debug('Debugging information');
}
}
```
# Conclusion
By using this `LogService`, you can gain better control over your logging output, ensuring that you have detailed logs in development while keeping your production environment clean and efficient. This approach not only enhances the maintainability of your application but also helps in adhering to best practices for logging in software development.
Stop scattering `console.log` statements in your code today and start using a structured logging service for a more robust and manageable application! | manojgohel |

published: true
description: Tips on how to use terminal application such as Powershell with NVDA screen reader.
tags: 'terminal, powershell, nvda, screenreader'
cover_image: null
canonical_url: null
---
When I first started using a screen reader, one of the biggest challenges I faced was operating terminal applications like Powershell. It took me quite some time to become comfortable navigating and using these terminal apps.
This article shares tips on operating Powershell and other terminal applications using the NVDA screen reader (Desktop keyboard layout), based on my personal experience. It is a work-in-progress article that will be updated over time.
## Reading Text in the Terminal
In the terminal, the cursor is always at the bottom. To read text, use the Navigator Object. For example, to read the previous line use `Numpad 7`for Desktop Layout. Full description about the Navigator Object navigation can be found in [NVDA Command Key Quick Reference](https://www.nvaccess.org/files/nvdaTracAttachments/455/keycommands%20with%20laptop%20keyboard%20layout.html) page.
## Copying Text
To copy a range of text in the terminal, follow these steps:
1. Mark the start of the text to be copied:
- Use the Navigator Object to move to the starting point of the text you want to copy.
- Press `Caps Lock` + `F9`.
2. Mark the end of the text:
- Use the Navigator Object to move to the endpoint of the text selection.
- Press `Caps Lock` + `F10` twice. (Hold the `Caps Lock` and then quickly press `F10` twice.)
After completing these steps, the selected text will be copied to the clipboard.

Today, we'll guide you on how to add dark mode to your Next.js app with the help of Tailwind CSS Typography. This duo doesn't just improve user experience but also gives your app a more attractive appearance.
Dark mode, which improves user experience by lessening eye strain and prolonging device battery life, has become a crucial component of contemporary web development. We will show you how to use Tailwind CSS and the `next-themes` library to implement dark mode in a Next.js application in this detailed guide. This methodology guarantees a smooth incorporation of dark mode, emphasising the utilisation of Tailwind CSS Typography to enhance content design.
## Prerequisites
Before we start, ensure you have the following installed:
- [Node.js](https://nodejs.org/en)
- [Next.js](https://nextjs.org/)
- [Tailwind CSS](https://tailwindcss.com/)
## Setting Up A Next.Js Project
First, create a new Next.js project,
```
npx create-next-app@latest dark-mode-nextjs
cd dark-mode-nextjs
```
Next, install Tailwind CSS and its dependencies,
```
npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init -p
```
Configure Tailwind CSS by editing `tailwind.config.js`,
```
module.exports = {
content: [
"./pages/**/*.{js,ts,jsx,tsx}",
"./components/**/*.{js,ts,jsx,tsx}",
],
theme: {
extend: {},
},
plugins: [
require('@tailwindcss/typography'),
],
}
```
Create the Tailwind CSS configuration file by adding the following to `./styles/globals.css`,
```
@tailwind base;
@tailwind components;
@tailwind utilities;
```
To manage dark mode, we'll use the `next-themes` library. Install it by running:
```
npm install next-themes
```
Next, create a `ThemeProvider` to wrap your application. Edit `pages/_app.js`:
```
import { ThemeProvider } from 'next-themes'
import '../styles/globals.css'
function MyApp({ Component, pageProps }) {
return (
<ThemeProvider attribute="class">
<Component {...pageProps} />
</ThemeProvider>
)
}
export default MyApp
```
Update your Tailwind CSS configuration to support dark mode,
```
module.exports = {
darkMode: 'class', // or 'media' or 'class'
content: [
"./pages/**/*.{js,ts,jsx,tsx}",
"./components/**/*.{js,ts,jsx,tsx}",
],
theme: {
extend: {},
},
plugins: [
require('@tailwindcss/typography'),
],
}
```
Create a button to toggle between light and dark modes. Add the following to a new file `components/ThemeToggle.js`,
```
import { useTheme } from 'next-themes'
import { useEffect, useState } from 'react'
export default function ThemeToggle() {
const { theme, setTheme } = useTheme()
const [mounted, setMounted] = useState(false)
useEffect(() => {
setMounted(true)
}, [])
if (!mounted) return null
return (
<button
onClick={() => setTheme(theme === 'dark' ? 'light' : 'dark')}
className="p-2 bg-gray-800 text-white rounded"
>
Toggle {theme === 'dark' ? 'Light' : 'Dark'}
</button>
)
}
```
Include the `ThemeToggle` component in your main layout or a specific page, such as `pages/index.js`,
```
import ThemeToggle from '../components/ThemeToggle'
export default function Home() {
return (
<div className="prose dark:prose-dark">
<h1 className="text-3xl font-bold">Welcome to Dark Mode in Next.js</h1>
<ThemeToggle />
<p>This is an example of using Tailwind CSS with dark mode support in Next.js.</p>
</div>
)
}
```
Tailwind CSS Typography provides beautiful default styles for your content. To leverage this, add the `prose` class to your content elements. The `dark:prose-dark` class will apply dark mode styles when the theme is set to dark.
Here's an example of how to use it in your `pages/index.js`:
```
export default function Home() {
return (
<div className="prose dark:prose-dark mx-auto">
<h1>Welcome to Dark Mode in Next.js</h1>
<ThemeToggle />
<p>
This example demonstrates the integration of dark mode using Tailwind CSS and `next-themes` in a Next.js application. The content is styled using Tailwind CSS Typography.
</p>
<h2>Why Dark Mode?</h2>
<p>
Dark mode can reduce eye strain, especially in low-light environments. It also helps in saving battery life on OLED screens.
</p>
<h2>Setting Up Tailwind CSS</h2>
<p>Follow the steps to configure Tailwind CSS and Tailwind CSS Typography in your Next.js project.</p>
</div>
)
}
```
## Conclusion
We have gone over how to use Tailwind CSS to set up a Next.js project and how to use `next-themes` to implement dark mode in this article. We also showed you how to use Tailwind CSS Typography to improve content. You can improve user experience by offering a fashionable and useful dark mode in your Next.js application by following these instructions.

1,915,228 | Why do AI articles trend on Dev.to? | I have been seeing a lot of obvious AI content trending on Dev.to. While I don't mind AI assisted... | 0 | 2024-07-08T05:50:34 | https://dev.to/paul_freeman/why-do-ai-articles-trend-on-devto-hh8 | discuss, ai, devto | I have been seeing a lot of obvious AI content trending on Dev.to. While I don't mind AI assisted writing, I do mind AI generated experience.
Here's an example, I saw on trending page recommended to me
>**Note** sorry for the black censoring, I don't want people to target them and cause unnecessary distress.
Though some of these writers have been called out, by people including dev.to staff, they continue to write AI garbage!
Technical blogs shouldn't entirely be generated by an AI. If I wanted to read AI blogs, why do I need to come to Dev.to? I could ask GPT to summarize a new topic everday, everyhour.
**You can generate content but not experience!**
## Pattern
Almost all the AI writers follow a similar pattern, they publish technical articles almost everyday, has in the world of, have a conclusion explicitly written like shown.
I don't care if they published AI garbage in their own profile, but, I do mind Dev.to encouraging it by bringing on trending page an main pages. When they get more likes, comments not only are they being actively encouraged to continue generating AI content, but also, encourages other writers to start publishing AI experience.
Eventually, actual experienced dev will leave the site and will be completely taken over by Bots
The other problem bigger problem arises when they start lying about their experience by showing the AI generated blogs to potential clients/ employer.
## Possible solutions
* Start bringing reputation for certain actions similar to Stackoverflow.
* Make this site a self-moderated, similar to Stackoverflow.
* Make it easier to flag AI generated experience, 3 AI flags and it would be put in moderators queue, and will no longer trend until the article is reviewed for AI content.
* Temp suspension from writing blogs, if almost all their blogs are AI content.
* Stop massive automated followers, yes, you need a starting point but, dev.to making auto following random people without limits serves no purpose and only encourages people to write random AI articles.
## other problem on dev page
Dev.to must stop encouraging thank you comments on **Technical articles**, they serve little to no purpose. Like the article? well there is a like button you can press to show appreciation.
The discussion must be related to the article written, bringing out important points or sometimes questions related to the article or the topic, other short comments such as "Thank you", "good read" are just noise, should be filtered towards the end in the comment list.
Sometimes, comments here feels very similar to LinkedIn Comments, I left that place a long time ago and I don't want to see it here as well.
## Promoting unrelated stuff under other people's blogs
Yes you have to promote to get people to start using your product or try your project, but promoting a very unrelated project under someone else's post, is just ruining the experience. There are people just going around asking for support for their project under every comment section, it just gets annoying after a point.
If you want to promote, promote in subtle ways by providing value, not by going to everyone else's blog post and pasting you link.
## Possible solution
* set a cool down period before they can comment again, if they have linked to same external source everywhere.
* Too much self-promo under, everyone else's blog? temp suspension from commenting and make links unclickable.
## Conclusion
In today's world, where bots and AI-generated content are prevalent, dev.to can stand out and can effectively combat bot-generated content and attract a community of experienced, genuine developers, ensuring high-quality, reliable articles and discussions.

1,915,230 | Now now now, now. | This post was originally written for my website at miko.ademagic.com/blog/now I've been interested... | 0 | 2024-07-08T05:16:34 | https://dev.to/ademagic/now-now-now-now-1jp4 | indieweb, webdev, website | > This post was originally written for my website at [miko.ademagic.com/blog/now](https://miko.ademagic.com/blog/now)
I've been interested in the Indie Web as a new (old?) way to connect with a community on the Internet without an algorith holding my hand (amongst other reasons, but that's for another post). One of the things I found a lot of people setting up was a [Now Page](https://nownownow.com/). I liked the idea, so I [made my own](https://miko.ademagic.com/now) a while back. If you have a personal website, I think you should too.
## A what now?
Yes. It's a page you put on your site with short-form, frequent(ish) updates similar to what you'd put on a post microblog. Read the [about](https://nownownow.com/about) page, it explains it a lot better than I could.
You let [Derek Sivers](https://sive.rs) know you have one, and he puts it into a directory, and people find you (or you find people). No recommendations, no promoted listings, no ranking, no preference or order – all just based on location and a bit of random ordering. It's beautiful.
## Why's that good?
Total creative freedom over what you want to build. No standards or structure to feed an algorithm. Share as much (or as little) as you want. Have it indexed, it's up to you. Then find like-minded people, see what they're doing, and learn from them. Or, don't make one and just browse! Pure old school Internet.
Since creating mine, I've already connected with others who have one. I've even made improvements to it and got inspiration for more.
I've had to make changes to my Now page a few times before, or have had questions about it, and all I've had to do is email Derek. He's responded like he was sitting next to me and I tapped him on the shoulder. Quick, straightforward, personable, and even constructive. This doesn't feel like it's a labor of love for him (though it might be, sorry Derek) – it all just seems _natural_. No revenue, no passion or ego behind this... he just seems to do this because this is what _should be done_.
But also, when's the last time you felt that the results you got from a search were totally unbiased? Not dependent on outside factors, like what's selling well, who's paying for engagement, or what people like you have viewed before? At the very least, there is a refreshing purity to this network that I haven't seen in a while and I want to get behind it.
But most of all, it's just fun. Get a now page, and let me know you have one! | ademagic |

In this article, we will debunk some misconceptions surrounding generative AI.
The arrival of super cool AI tools like ChatGPT, Midjourney, and DALL-E has everyone talking. These tools are changing how we create stuff and are becoming a big part of our lives. But with all the excitement, there are also a lot of misunderstandings about what AI can really do.
Some people are scared of AI, thinking it's here to take over. Others see it as a super helpful tool that can change the world for the better. This confusion comes from not really knowing what AI can and can't do.
The truth is, AI is a powerful tool, but it's not here to steal our jobs or take over the world. It's actually here to help us. As AI gets more popular in our work and personal lives, it's important to talk about how to use it responsibly. This means making sure AI is developed in a fair way and thinking about how it will affect people and society.
In this blog, we'll debunk common misconceptions about AI's capabilities. We'll clear up the confusion and highlight how AI can be used for positive change. So, get ready to explore the incredible potential of AI without any fear.
## Popular Myths Surrounding Generative AI Technology
## Myth 1: Generative AI is always Infallible
Generative AI's capacity to produce content on demand is remarkable. However, a critical question arises: how trustworthy and accurate is its output?
Generative AI technology sifts through massive quantities of online data to respond to our prompts. While its algorithms excel at parsing existing text, they lack the ability to discern fact from fiction. This creates a substantial risk of generating inaccurate or misleading content.
Despite its impressive capabilities, relying solely on AI without human oversight can result in unverified and potentially deceptive outputs. These fabricated pieces of information are often referred to as "hallucinations" – essentially, AI inventing details based on patterns in its data.
To safeguard against misinformation, human validation remains indispensable. AI is a powerful instrument, but it should be treated as just that – an instrument, not an infallible source of truth.
## Myth 2: Generative AI will replace human creativity
Generative AI possesses remarkable abilities. It learns at an astonishing pace, digesting vast amounts of information in mere seconds and producing content from simple prompts. Its capacity to create with minimal input and time raises questions about the nature of creativity itself.
However, the reality is more complex. AI excels at mimicking existing styles and generating content based on patterns found in its training data. It can be a valuable asset for producing variations on established themes or adhering to specific style guidelines.
Yet, AI currently lacks the intangible qualities that define human creativity. It doesn't possess the intuitive understanding, emotional depth, and raw originality that fuel our capacity to create something truly novel. Human creativity is a multifaceted process, drawing upon our social experiences, cultural influences, and a deep well of emotions – aspects that current AI struggles to replicate.
Ultimately, AI is a powerful tool for remixing and reimagining existing ideas, but it's not yet capable of replacing the spark of human ingenuity.
## Myth 3: The bigger the AI models, The Better
Following the debut of OpenAI's ChatGPT, the focus has been on creating larger language models. GPT-2 had 1.5 billion parameters, GPT-3 had 175 billion, and a possible GPT-4 might have a trillion. Initially, generative AI prioritized bigger datasets, assuming that more data automatically leads to improved results.
However, recent research has challenged this assumption. New studies suggest that size alone does not guarantee better performance. In 2020, OpenAI's Kaplan et al. proposed "Kaplan's law," suggesting a positive relationship between model size and performance. But a recent paper from Deepmind Research explores this further. It argues that the amount of training data (the individual pieces of text given to the model) is equally important.
This paper introduces Chinchilla, a model with 70 billion parameters - much smaller than its predecessors. Yet, Chinchilla was trained on four times the amount of data. The results are notable – Chinchilla surpasses larger models in certain areas like common sense and closed book question answering benchmarks.
This research highlights a significant change in how generative AI is trained. It suggests that concentrating solely on model size may not be the most effective strategy. Finding the right balance between model architecture and the quality and quantity of training data seems to be crucial for realizing the full potential of generative AI.
## Myth 4: A single LLM to rule them all
LLM is short for "Large Language Model." These are AI models trained on huge amounts of data, allowing them to understand and create text that sounds like a human wrote it. However, the idea that one LLM can do everything we need for language tasks is still not a reality.
It's important to know that using just one language model (LLM) isn't always the best choice. For example, different generative AI applications like Gemini and ChatGPT use different LLMs. Gemini's responses are designed for conversation, while ChatGPT's responses are more focused on providing information.
Different companies and industries have their own ways of communicating and specific needs. One LLM might not be able to match the exact writing style needed for a legal document compared to a marketing brochure.
## Myth 5: Generative AI tools are free or have minimal cost
Generative AI models need regular maintenance, adjustments, and possibly retraining with updated information to maintain their effectiveness and prevent the creation of biased or incorrect results.
While some basic versions of tools like ChatGPT or Gemini are accessible at no cost or a lower price, accessing the full capabilities of these technologies typically involves a higher cost. For example, advanced versions such as GPT-4 necessitate a monthly subscription fee, often surpassing $20, and Microsoft's CoPilot further increases this expense to $30 per month.
## Myth 6: Adopting Generative AI technology in business provides competitive edge
Generative AI is becoming increasingly popular in the business world, with major tech companies and various businesses adopting AI to enhance their efficiency and productivity.
It's crucial for business leaders to recognize that simply implementing AI doesn't automatically guarantee a competitive advantage. Businesses need to be creative in their AI strategies to effectively leverage them in achieving their goals. The methods and timing of AI usage are equally important, as misusing it can put you behind your competitors.
A recent study by BCG revealed that 90% of participants utilizing GPT-4 for creative tasks experienced a significant 40% improvement in performance compared to those who didn't. However, those using it for business problem-solving saw a 23% decline.
Business leaders should be mindful of the challenges associated with implementing generative AI. Utilizing AI for tasks that align with its strengths, such as generating creative content, can unlock substantial benefits. However, forcing it into areas where human judgment and reasoning are essential, like complex problem-solving, can have negative consequences.
**Conclusion**
Generative AI, while capable, is not perfect. It's important to understand that the accuracy of generative AI depends on the quality of the data it learns from. It's also important to remember that it's not designed to replace human creativity, but to help us be more creative and solve problems in new ways.
Even with its potential, there are ethical issues that need to be addressed. We need to think about privacy risks, how data is used, potential biases in the information it creates, and how to use AI-generated content responsibly.
The future of generative AI looks promising, but we need to approach it carefully. By understanding its benefits and limitations, we can make sure it helps everyone. | vikas_brilworks | |
1,915,237 | Implementing the Page Object Model (POM) with Cypress: A Step-by-Step Guide | Introduction As web applications grow in complexity, maintaining test automation code... | 0 | 2024-07-09T06:46:08 | https://dev.to/aswani25/implementing-the-page-object-model-pom-with-cypress-a-step-by-step-guide-5c2i | testing, javascript, webdev, cypress | ## Introduction
As web applications grow in complexity, maintaining test automation code becomes increasingly challenging. The Page Object Model (POM) is a design pattern that can help manage this complexity by promoting reusability and maintainability in your test automation scripts. In this post, we’ll explore how to implement the POM framework using Cypress, a modern end-to-end testing tool for web applications.
## What is the Page Object Model (POM)?
The Page Object Model is a design pattern that encapsulates web page elements and interactions within classes or objects. Each page or component of your web application is represented by a corresponding page object. This separation of concerns makes your tests cleaner, more readable, and easier to maintain.
## Benefits of Using POM
**1. Reusability:** Common page elements and interactions are defined once and reused across multiple tests.
**2. Maintainability:** Changes in the UI require updates in only one place, reducing the effort needed to maintain tests.
**3. Readability:** Tests become more readable and easier to understand, as they focus on the test logic rather than the underlying page details.
## Setting Up Cypress with POM
**Step 1: Install Cypress**
First, make sure you have Node.js installed. Then, install Cypress via npm:
```
npm install cypress --save-dev
```
**Step 2: Project Structure**
Organize your project to accommodate page objects. A typical structure might look like this:
```html
cypress/
|__ fixtures/
|__ e2e/
|__ tests/
|__ login.spec.js
|__ support/
|__ commands.js
|__ index.js
|__ pageObjects/
|__ LoginPage.js
|__ HomePage.js
```
**Step 3: Define Page Objects**
Create a page object for each page or component of your application. Here’s an example of a `LoginPage` object:
```js
// cypress/support/pageObjects/LoginPage.js
class LoginPage {
visit() {
cy.visit('/login');
}
fillEmail(email) {
cy.get('input[name=email]').type(email);
}
fillPassword(password) {
cy.get('input[name=password]').type(password);
}
submit() {
cy.get('button[type=submit]').click();
}
}
export default LoginPage;
```
**Step 4: Use Page Objects in Tests**
Now, use the page objects in your tests to interact with the application:
```js
// cypress/e2e/tests/login.spec.js
import LoginPage from '../../support/pageObjects/LoginPage';
describe('Login Tests', () => {
const loginPage = new LoginPage();
it('Should login with valid credentials', () => {
loginPage.visit();
loginPage.fillEmail('test@example.com');
loginPage.fillPassword('password123');
loginPage.submit();
cy.url().should('include', '/dashboard');
});
});
```
## Best Practices for Using POM with Cypress
**1. Encapsulate Page Logic:** Keep all page-specific logic within the page object. Tests should only use methods from the page object.
**2. Avoid Hardcoding Selectors:** Use data attributes for selectors to make tests more resilient to changes in the UI.
**3. Modularize Common Actions:** Create methods in page objects for common actions (e.g., login, logout) to promote reuse and reduce duplication.
**4. Use Fixtures for Test Data:** Store test data in fixtures to keep your test code clean and maintainable.
## Advanced Tips
**1. Command Overriding:** Extend Cypress commands using `Cypress.Commands.add` to include custom logic that simplifies test writing.
**2. Parallel Testing:** Leverage Cypress Dashboard for parallel test execution, speeding up your test suite.
**3. Error Handling:** Implement robust error handling within page objects to make tests more reliable and informative.
## Conclusion
Implementing the Page Object Model with Cypress can greatly enhance the maintainability and readability of your test automation scripts. By encapsulating page-specific logic within page objects, you can create a more modular and reusable test codebase. Follow the steps and best practices outlined in this post to get started with POM in your Cypress projects, and unlock the full potential of your test automation efforts.

That is way to save your... | 0 | 2024-07-08T05:25:31 | https://dev.to/manhvanvu/elixir-pattern-matching-save-your-time-and-friendly-with-your-brain-way-d8c | elixir, patternmatching, bitstring, binary | ## Intro
Once of interesting features of Elixir is pattern matching. That is way to save your time and similar with the way of our thinking.
Pattern matching help us to check value, extract value from complex term, branching code.
It also is a way to fail fast, follow "Let it crash" (and supervisor will fix) idiomatic of Erlang.
## How to uses
Pattern matching is always return original term (value of variable/expression) for us can continue using it for other expression.
Three things we need to care in here:
* If not match it will raise an error.
* Pattern matching is always return original term.
* If we add a variable for extracting, after matched variable will have value we expected.
With '=', pattern is in the left side, original term in right side.
With function, pattern is placed in argument.
No we go to two use cases for using pattern matching.
**check similar(condition) value**
This type of pattern matching can help us verify a value, format of variable/param.
Term is matched with pattern ({:ok, "hello"} = {:ok, "hello"}):
_(check value and return original term)_
Term is unmatched with pattern ({:ok, "abc"} = {:ok, "hello"}):
_(term is unmatched with pattern, raise an runtime error)_
For case using pattern in function, if pattern is unmatched with argument, Elixir will check with next function. If no function is matched with the pattern, an runtime error will be raised.
Simple we can check a atom like:
```Elixir
a = :an_atom
b = 1_000
c = {:ok, 1}
# ...
# use case 1
:an_atom = a
1_000 = b
{:ok, 1} = c
# use case 2
case a do
:an_atom ->
:ok
_other ->
:nok
end
case b do
1_000 ->
:default
_ ->
:user_config
end
# use case 3
check_ok = fn
:ok -> true
_ -> false
end
result = check_ok.(a)
```
For case check equal value, that usually uses for verifying value, condition for branch code in function/case do.
If variable is complex term example a tuple, list, map. We can discard other values to check one or more values we want.
Example:
```Elixir
list = [1, :a, "hello"]
tuple = {:ok, :a, 1}
map = %{a: 1, b: "hello"}
# check first item of list is 1.
[1|_] = list # or ^list = [1|_]
# check tuple has same values.
copy = ^tuple = {:ok, :a, 1}
# check tuple has same number of elements.
{_, _, _} = tuple
# check map has a key = :a and value of key = 1.
%{a: 1} = map
```
**Extracting value**
This feature of pattern matching help us can extract one or more value from a complex term.
Remember, our expected value will bind to variable follow format of our pattern or key in map case.
_(expression of pattern matching:
{:ok, get_value} = {:ok, "hello"}.
after matched, we got "hello" value from original term)_
Example:
```Elixir
tuple = {:ok, "hello"}
list = [:a, :b, 1, 2]
complex = {:ok, [{:first, 1}, {:second, [1, 2, 3]}]}
# extract second element of tuple
{:ok, value} = tuple
# get first item in list
[firt|_] = list
# get second item in list
[_, second|_] = list
# get value of result
{:ok, [{_, first_value}, {:second, second_value}]} = complex
```
We can use all key of example for function like:
```Elixir
defmodule Example do
def process_second([_, second|_]) do
# do something with second item.
IO.puts("Value of second item: #{inspect second}")
second
end
def extract_map(%{a: value} = map) do
# do some thing with value & map.
IO.puts("key a has value = #{inspect value}")
value
end
end
# use cases for pattern matching in function arguments.
list = [1, :default, "hello"]
map = %{a: "hello", b: "world"}
Example.process_second(list)
Example.extract_map(map)
```
Other common cases for pattern matching with head of function are separating code like:
```Elixir
defmodule Exam do
def process_result({:error, reason}) do
# do something with error case.
end
def process_result({:ok, result}) do
# do something with result.
end
end
```
## Pattern matching with Binary/Bitstring
This is interesting way to work with binary in Elixir. I wish other languages have this feature.
We have two type of raw data is binary (for work with byte) and bitstring (for work with bit).
Elixir has very convenient way to work with raw data like binary and bitstring. We can construct and matching these easily.
In this topic we just go to how to match a binary or bitstring only.
**Binary matching**
Example:
```Elixir
# each byte is an integer 8 bit.
bin = <<1, 2, 3, 4, 5>>
# Get first byte
<<first, rest::binary>> = bin
# Get second byte
<<1, second, rest::binary>> = bin
# get 2 bytes in head of binary
<<head::binary-size(2), rest::binary>> = bin
```
Is it simple right?
**Bitstring matching**
We can match & get single bit from a raw data (bitstring).
Example:
```Elixir
bit = <<3::4, 1::4, 3::4, 0::4>>
# get first 8 bits from bitstring.
<<first_4::bitstring-size(8), rest::bitstring>> = bit
# get 4 bits after first 4 bits is match to <<3::4>> and store to get_4_bits variable
<<3::4, get_4_bits::bitstring-size(4), _>> = bit
```
We can easy to process raw data with pattern matching.

1,915,240 | Explaining ‘this’ keyword in JavaScript | 1. Global Context When used in the global context (outside of any function), this refers... | 0 | 2024-07-08T05:26:32 | https://dev.to/imrul099/explaining-this-keyword-in-javascript-15hm | javascript, webdev, frontend, programming | ## 1. Global Context
When used in the global context (outside of any function), this refers to the global object, which is window in browsers and global in Node.js.
`console.log(this); // In a browser, this logs the Window object
`
## 2. Function Context
In a regular function, the value of this depends on how the function is called.
**a. Function Invocation**
When a function is called as a standalone function, this refers to the global object (in non-strict mode) or undefined (in strict mode).
```
function foo() {
console.log(this);
}
foo(); // In non-strict mode, logs the global object (Window in browsers)
// In strict mode, logs undefined
```
**b. Method Invocation**
When a function is called as a method of an object, this refers to the object the method is called on.
```
const obj = {
method: function() {
console.log(this);
}
};
obj.method(); // Logs the obj object
```
**c. Constructor Invocation**
When a function is used as a constructor (with the new keyword), this refers to the newly created object.
```
function Person(name) {
this.name = name;
}
const person = new Person('Alice');
console.log(person.name); // Logs 'Alice'
```
## 3. Arrow Functions
Arrow functions (=>) do not have their own this binding. Instead, this is lexically inherited from the outer function where the arrow function is defined.
```
const obj = {
regularFunction: function() {
console.log(this); // Logs obj
const arrowFunction = () => {
console.log(this); // Logs obj because it inherits `this` from regularFunction
};
arrowFunction();
}
};
obj.regularFunction();
```
## 4. Event Handlers
In DOM event handlers, this refers to the element that received the event.
```
document.getElementById('myButton').addEventListener('click', function() {
console.log(this); // Logs the button element
});
```
## 5. Explicit Binding
JavaScript provides methods to explicitly set the value of this using call, apply, and bind.
**a. call and apply**
call and apply methods call a function with a specified this value and arguments. The difference between them is how they handle arguments.
```
function greet(greeting) {
console.log(greeting + ', ' + this.name);
}
const person = { name: 'Alice' };
greet.call(person, 'Hello'); // Logs 'Hello, Alice'
greet.apply(person, ['Hi']); // Logs 'Hi, Alice'
```
**b. bind**
bind creates a new function that, when called, has its this keyword set to the provided value.
```
function greet() {
console.log(this.name);
}
const person = { name: 'Alice' };
const boundGreet = greet.bind(person);
boundGreet(); // Logs 'Alice'
```
## Summary
**Global context:** this refers to the global object.
**Function context:**
Regular function: this is the global object or undefined in strict mode.
Method: this is the object the method belongs to.
Constructor: this is the new object being created.
**Arrow functions**: this is lexically inherited from the outer function.
**Event handlers:** this is the event target element.
**Explicit binding:** Use call, apply, and bind to explicitly set this. | imrul099 |
1,915,241 | How to Decommission Exchange 2019? | There are multiple reasons why you need to decommission an Exchange Server. Some common reasons... | 0 | 2024-07-08T05:36:47 | https://dev.to/abhaysingh/how-to-decommission-exchange-2019-pi0 | There are multiple reasons why you need to decommission an Exchange Server. Some common reasons include:
1. Hardware issues with the current server.
2. Moving to a new hardware or new operating system.
3. Downsizing from Database Availability Group (DAG).
4. Issues with the currently installed operating system.
5. Migrating to Microsoft 365.
6. Merging two Exchange Servers into one.
However, you cannot just decommission the Exchange Server. You need to follow a proper procedure to avoid any issues and consequences. As you’re aware, all the Exchange Server configuration is stored in the Active Directory schema. So, if a server is forcedly removed, there will be trails and configurations in the schema which can cause issues when introducing a new Exchange Server or with other servers. In this article, we will discuss the procedure to decommission the Exchange 2019 Server.
## Procedure to Decommission Exchange 2019 Server
Below, we will be discussing the stepwise procedure to decommission an Exchange Server.
### 1. Review the Exchange Server Virtual Directories
Exchange Server works with virtual directories for Exchange Web Services (EWS), Exchange Control Panel (ECP), Outlook Web Access (OWA), Offline Address Book (OAB) and others. Before decommissioning the current Exchange Server, you need to check and ensure that these are working with the internal and external URLs on the new server. For this,
- Open the Exchange Admin Center (EAC). Click on Servers and then Virtual Directories.
- Next, open the virtual directories and confirm that both internal and external URLs (if any) are working and accessible from outside and routed to the new server. You need to check this for each virtual directory.
You can also check if the Auto Discover server is pointing to the right server. To verify this, use the below PowerShell command.
```
Get-ClientAccessService | Select-Object AutoDiscoverServiceInternalUri
```
### 2. Confirm Send or Receive Connectors are Configured
Custom send connectors are created for various reasons, such as email relay (unauthenticated) from servers or devices, multifunctional printers to scan, alarm systems, security systems such as CCTV, etc.
So, you should check for any custom send connectors and create them on the new server. To check if send connectors are configured on the server you’re going to decommission, you can use the following command.
```
Get-SendConnector | Format-Table Name, SourceTransportServers -AutoSize
```
To check the receive connectors, you can run the following command.
```
Get-ReceiveConnector -Server <Server To Decommission>
```
The above commands will give you the details that can help you review the mail flow and transpose any custom send connectors to the new server. In addition, you will get a list of devices that are relaying through the server. This will allow you to change the devices SMTP server to point to the new server.
### 3. Shift the Email Delivery Service and Change Network Rules
Apart from devices configurations, you need to also change the rules on the network. You need the network team or the network administrator to change the rules in the network to pass all the email traffic internally or via other subnet. From the outside, any ports like 443 for the Outlook Web Access and other ports such as 25, need to be changed so that these are forwarded to the new server.
### 4. Put the Server in Maintenance Mode
Before removing the server, you can put the Exchange Server you’re going to decommission in maintenance mode. This helps you to ensure that everything is working and routing through the new server after the server is turned off.
To put the server in maintenance mode, you can run the following command.
```
Set-ServerComponentState "<Server Name>" -Component ServerWideOffline -State Inactive -Requester Maintenance
```
You can use the below command to verify that the server is in maintenance mode.
```
Get-ServerComponentState -Identity "<Server Name>"
```
From the results, check that the ServerWideOffline component is Inactive.
### 5. Uninstall the Exchange Server 2019
At this stage, you should have moved all the mailboxes to the new server. Now the final step is to safely decommission the Exchange Server. To do so, go to the Control Panel > Add Remove programs of the old server and uninstall the Exchange Server. This will uninstall the server as well as change the Active Directory and clean all the references of the server.
## To Conclude
Above, we have explained the stepwise process to safely remove or decommission the Exchange 2019 Server. After the server has been decommissioned, it might happen that there were some mailbox databases with some important mailboxes which were not migrated to the new server. Restoring those mailboxes after decommissioning the server would be a hassle. This will consume a considerable amount of administrative effort and resources.
However, you can use specialized applications, like [Stellar Converter for EDB](https://www.stellarinfo.com/email-repair/edb-pst-converter.php). This application can open standalone offline databases from any Exchange version and of any size. It then allows to granularly export the mailboxes and other data from EDB file to PST and other file formats. You can also use the application to migrate user mailboxes, user archives, disabled mailboxes, shared mailboxes, and public folders, directly to a live Exchange Server or Office 365 with automatic mailbox matching.

## Introduction
LLMs have unlocked countless opportunities to tackle once unsolvable problems, thanks to their exceptional reasoning and decision-making capabilities. Among their many strengths, one of the most significant is their general code understanding, which can be leveraged to build tools that write, re-write, and review code.
Building on this capability, in this article, you will create an AI Agent that reviews GitHub pull requests, posts them as a comment in GitHub, and sends a summary of it to a configured Slack channel. For this, you will use LangChain Agents and Composio tools.
## Key Objectives
- Understand what Composio is.
- Learn about LangChain and building agents with it.
- Understand the workflow of the PR agent.
- Learn how to build the agent with LangChain and Composio.
## What is Composio?
[Composio](https://www.composio.dev/) is an open-source platform that provides tools and integrations for building AI agents. Many applications like Slack, GitHub, Linear, etc., require complex user authentication and authorization mechanisms, and adding these integrations to your agentic workflow can be quite challenging. Composio addresses this by offering built-in user authentication and authorization management to streamline your AI application development workflow. It also lets you add applications with only a few lines of code. Composio offers an easy way to integrate your application with AI agents.
Composio supports authentication mechanisms such as OAuth, JWT, ApiKey, and basic authentication. It handles the authentication and authorization of your users, enabling the agents to integrate tools to perform actions on behalf of your users.
For this walkthrough, you need to understand two key Composio concepts:
- **Actions**: In Composio, actions are tasks performed on behalf of the users. For instance, if you have configured a GitHub integration, you can perform actions like starting a repository, updating the README file, etc. Composio wraps all the GitHub API features and optimizes them for LLM tool calls.
- **Triggers**: Triggers are predefined conditions that, when met, initiate actions from your agents. Composio offers a built-in webhook to capture trigger events. The webhooks receive a payload from integrations in real time, letting you perform actions on event data. For example, if a `slack_receive_message` trigger is configured for your Slack integration, the Slack app will send the event data like text, time, and channel ID to the webhook at the backend.
## What is LangChain?
LangChain is an open-source framework for AI-powered applications. It offers LLM chains, vector stores, graph stores, databases, document loaders, parsers, and many more components to build a complete backend for AI applications. Because of its versatility and popularity, it has become the default choice for building AI-powered systems.
In this article, you will use LangChain Agents and other components with Composio tools to build the PR agent.
## Workflow Overview
The workflow involves a Slack bot, your GitHub app integration, a webhook at the backend, and a LangChain Agent.
With Composio, you can integrate a Slack bot and connect to GitHub. The Slack integration allows you to send and receive messages within Slack channels, while the GitHub integration enables you to fetch pull request diffs.
When someone makes a pull request to the configured repository, the trigger activates and sends the event data to the backend webhook. The event payload is then forwarded to the LangChain agent. Following the provided instructions, the agent reviews the code, summarizes it, posts the review as a comment on the pull request, and also sends the summary to the configured Slack channel.
## Prerequisites
To complete this tutorial, you will need a Composio account and access to the GPT-4 API. You can create a free Composio account [here](https://composio.com/signup). Consider using Mixtral 8x7B from Groq as an alternative OpenAI GPT-4.
Get the API keys for both Composio and the LLM provider. For Composio, click on the Settings tab to view your API key.
## Building the PR Agent
Now that you have grasped the basics of Composio and understood the workflow, let's build the agent. But before that, let’s set up the development environment.
### Step 1: Setting up Development Environment
Create a virtual environment using Python Venv:
```
python -m venv myenv
source myenv/bin/activate # On Windows use `myenv\Scripts\activate`
```
Install the following libraries.
```
pip install composio-core composio-langchain /
langchain-openai/
python-dotenv
```
## Step 2: Setting Environment Variables
Create a `*.env*` file and add the following environment variables:
```
COMPOSIO_API_KEY=your Composio API key
OPENAI_API_KEY=your OpenAI API key
SLACK_CHANNEL_ID=slack channel ID, you want the summary posted
```
To authenticate your Composio account, run the following command and follow the login flow:
```
composio login
```
## Step 3: Defining Tools and LLM
Now, import the libraries and define the required tools and LLM.
```
import os
from dotenv import load_dotenv
from composio_langchain import Action, ComposioToolSet
from langchain import hub
from langchain.agents import AgentExecutor, create_openai_functions_agent
from langchain_openai import ChatOpenAI
from composio.client.collections import TriggerEventData
load_dotenv()
# Initialize the ComposioToolSet
composio_toolset = ComposioToolSet()
# Define the tools
pr_agent_tools = composio_toolset.get_actions(
actions=[
Action.GITHUB_GET_CODE_CHANGES_IN_PR,
Action.GITHUB_PULLS_CREATE_REVIEW_COMMENT,
Action.GITHUB_ISSUES_CREATE,
Action.SLACKBOT_CHAT_POST_MESSAGE,
]
)
# Initialize the language model
llm = ChatOpenAI(model="gpt-4")
```
We are using four different actions from Composio. Each action performs a single specific task:
- **Action.GITHUB_GET_CODE_CHANGES_IN_PR**: Retrieves the code changes in a GitHub pull request.
- **Action.GITHUB_PULLS_CREATE_REVIEW_COMMENT**: Creates a review comment on a GitHub pull request.
- **Action.GITHUB_ISSUES_CREATE**: Creates a new issue in a GitHub repository.
- **Action.SLACKBOT_CHAT_POST_MESSAGE**: Sends a message to a Slack channel using a Slack bot.
## Step 4: Defining the LangChain Agent
Next, define the OpenAI functions agent from LangChain with a system prompt to provide context about the workflow, LLM, and tools.
```
code_review_assistant_prompt = """
You are an experienced code reviewer.
Your task is to review the provided file diff and give constructive feedback.
Follow these steps:
1. Identify if the file contains significant logic changes.
2. Summarize the changes in the diff in clear and concise English, within 100 words.
3. Provide actionable suggestions if there are any issues in the code.
Once you have decided on the changes, for any TODOs, create a GitHub issue.
And send the summary of the PR review to """+os.environ['CHANNEL_ID']+""" channel on Slack. Slack doesn't have markdown so send a plain text message.
Also, add the comprehensive review to the PR as a comment.
"""
prompt = hub.pull("hwchase17/openai-functions-agent")
combined_prompt = prompt+code_review_assistant_prompt
query_agent = create_openai_functions_agent(llm, pr_agent_tools, combined_prompt)
agent_executor = AgentExecutor(agent=query_agent, tools=pr_agent_tools, verbose=True)
print("Assistant is ready")
```
## Step 5: Defining the Event Listener
Finally, define the event listener. This will be used to capture event payloads from the GitHub trigger. Composio's built-in event listener webhook can be configured to pick event data only from relevant trigger events.
```
# Create a trigger listener
listener = composio_toolset.create_trigger_listener()
@listener.callback(filters={"trigger_name": "github_pull_request_event"})
def review_new_pr(event: TriggerEventData) -> None:
# Using the information from Trigger, execute the agent
code_to_review = str(event.payload)
query_task = f"Review the following code changes: {code_to_review}"
# Execute the agent
res = agent_executor.invoke({"input": query_task})
print(res)
print("Listener started!")
print("Create a pr to get the review")
listener.listen()
```
In the code above, the callback function review_new_pr is invoked, when a PR is raised in the repository. The function receives the event data which is then passed to agent_executor. The agent executes the task as explained earlier.
Putting everything together.
```
import os
from dotenv import load_dotenv
from composio_langchain import Action, ComposioToolSet
from langchain import hub
from langchain.agents import AgentExecutor, create_openai_functions_agent
from langchain_openai import ChatOpenAI
from composio.client.collections import TriggerEventData
load_dotenv()
# Initialize the ComposioToolSet
composio_toolset = ComposioToolSet()

Recently, I saw BuOu's Quantitative Diary mentioning that you can use negatively correlated currencies to select currencies, and open positions to make profits based on price difference breakthroughs. Digital currencies are basically positively correlated, and only a few currencies are negatively correlated, often with special market conditions, such as the independent market conditions of MEME coins, which are completely different from the market trend. These currencies can be selected and go long after the breakthrough. This method can make profits under specific market conditions. However, the most common method in the field of quantitative trading is to use positive correlation for paired trading. This article will introduce this strategy briefly.
Digital currency pair trading is a trading strategy based on statistical arbitrage, which simultaneously buys and sells two highly correlated cryptocurrencies to obtain profits from price deviations. This article will introduce the principles of this strategy, profit mechanism, methods of selecting currencies, potential risks and ways to improve them, and provide some practical Python code examples.
## Strategy Principle
Pair trading strategies rely on the historical correlation between the prices of two digital currencies. When the prices of two currencies show a strong correlation, their price trends are generally in sync. If the price ratio between the two deviates significantly at a certain moment, it can be considered a temporary abnormality and the price will tend to return to normal levels. The digital currency market is highly interconnected. When a major digital currency (such as Bitcoin) fluctuates significantly, it will usually trigger a coordinated reaction in other digital currencies. Some currencies may have a very obvious positive correlation that can last due to the same investment institutions, the same market makers, and the same track. Some currencies are negatively correlated, but there are fewer negatively correlated currencies, and since they are all affected by the market trend, they will often have consistent market trends.
Assume that currency A and currency B have a high price correlation. At a certain moment, the average value of the A/B price ratio is 1. If at a certain moment, the A/B price ratio deviates by more than 0.001, that is, more than 1.001, then you can trade in the following ways: Open a long position on B and open a short position on A. On the contrary, when the A/B price ratio is lower than 0.999: Open a long position on A and open a short position on B.
The key to profitability lies in the spread gains when prices deviate from the mean and return to normal. Since price deviations are usually short-lived, traders can close their positions when prices return to the mean and profit from the spread.
## Prepare the Data
### Import the corresponding library
These codes can be used directly. It is best to download Anancoda and debug it in Jupyer notebook. It includes packages for commonly used data analysis directly.
```
import requests
from datetime import date,datetime
import time
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import requests, zipfile, io
%matplotlib inline
```
### Get all trading pairs being traded
```
Info = requests.get('https://fapi.binance.com/fapi/v1/exchangeInfo')
b_symbols = [s['symbol'] for s in Info.json()['symbols'] if s['contractType'] == 'PERPETUAL' and s['status'] == 'TRADING' and s['quoteAsset'] == 'USDT']
b_symbols = list(filter(lambda x: x[-4:] == 'USDT', [s.split('_')[0] for s in b_symbols]))
b_symbols = [x[:-4] for x in b_symbols]
print(b_symbols) # Get all trading pairs being traded
```
### Download K-line function
The main function of the GetKlines function is to obtain the historical K-line data of the specified trading pair perpetual contract from the Binance exchange and store the data in a Pandas DataFrame. The K-line data includes information such as opening price, highest price, lowest price, closing price, and trading volume. This time we mainly use the closing price data.
```
def GetKlines(symbol='BTCUSDT',start='2020-8-10',end='2024-7-01',period='1h',base='fapi',v = 'v1'):
Klines = []
start_time = int(time.mktime(datetime.strptime(start, "%Y-%m-%d").timetuple()))*1000 + 8*60*60*1000
end_time = min(int(time.mktime(datetime.strptime(end, "%Y-%m-%d").timetuple()))*1000 + 8*60*60*1000,time.time()*1000)
intervel_map = {'m':60*1000,'h':60*60*1000,'d':24*60*60*1000}
while start_time < end_time:
time.sleep(0.3)
mid_time = start_time+1000*int(period[:-1])*intervel_map[period[-1]]
url = 'https://'+base+'.binance.com/'+base+'/'+v+'/klines?symbol=%s&interval=%s&startTime=%s&endTime=%s&limit=1000'%(symbol,period,start_time,mid_time)
res = requests.get(url)
res_list = res.json()
if type(res_list) == list and len(res_list) > 0:
start_time = res_list[-1][0]+int(period[:-1])*intervel_map[period[-1]]
Klines += res_list
if type(res_list) == list and len(res_list) == 0:
start_time = start_time+1000*int(period[:-1])*intervel_map[period[-1]]
if mid_time >= end_time:
break
df = pd.DataFrame(Klines,columns=['time','open','high','low','close','amount','end_time','volume','count','buy_amount','buy_volume','null']).astype('float')
df.index = pd.to_datetime(df.time,unit='ms')
return df
```
### Download data
The data volume is relatively large. In order to download faster, only the hourly K-line data of the last three months is obtained. df_close contains the closing price data of all currencies.
```
start_date = '2024-04-01'
end_date = '2024-07-05'
period = '1h'
df_dict = {}
for symbol in b_symbols:
print(symbol)
if symbol in df_dict.keys():
continue
df_s = GetKlines(symbol=symbol+'USDT',start=start_date,end=end_date,period=period)
if not df_s.empty:
df_dict[symbol] = df_s
df_close = pd.DataFrame(index=pd.date_range(start=start_date, end=end_date, freq=period),columns=df_dict.keys())
for symbol in symbols:
df_close[symbol] = df_dict[symbol].close
df_close = df_close.dropna(how='all')
```
## Backtesting Engine
We define an exchange object for the following backtest.
```
class Exchange:
def __init__(self, trade_symbols, fee=0.0002, initial_balance=10000):
self.initial_balance = initial_balance #Initial assets
self.fee = fee
self.trade_symbols = trade_symbols
self.account = {'USDT':{'realised_profit':0, 'unrealised_profit':0, 'total':initial_balance,
'fee':0, 'leverage':0, 'hold':0, 'long':0, 'short':0}}
for symbol in trade_symbols:
self.account[symbol] = {'amount':0, 'hold_price':0, 'value':0, 'price':0, 'realised_profit':0,'unrealised_profit':0,'fee':0}
def Trade(self, symbol, direction, price, amount):
cover_amount = 0 if direction*self.account[symbol]['amount'] >=0 else min(abs(self.account[symbol]['amount']), amount)
open_amount = amount - cover_amount
self.account['USDT']['realised_profit'] -= price*amount*self.fee #Deduction fee
self.account['USDT']['fee'] += price*amount*self.fee
self.account[symbol]['fee'] += price*amount*self.fee
if cover_amount > 0: #Close the position first
self.account['USDT']['realised_profit'] += -direction*(price - self.account[symbol]['hold_price'])*cover_amount #profit
self.account[symbol]['realised_profit'] += -direction*(price - self.account[symbol]['hold_price'])*cover_amount
self.account[symbol]['amount'] -= -direction*cover_amount
self.account[symbol]['hold_price'] = 0 if self.account[symbol]['amount'] == 0 else self.account[symbol]['hold_price']
if open_amount > 0:
total_cost = self.account[symbol]['hold_price']*direction*self.account[symbol]['amount'] + price*open_amount
total_amount = direction*self.account[symbol]['amount']+open_amount
self.account[symbol]['hold_price'] = total_cost/total_amount
self.account[symbol]['amount'] += direction*open_amount
def Buy(self, symbol, price, amount):
self.Trade(symbol, 1, price, amount)
def Sell(self, symbol, price, amount):
self.Trade(symbol, -1, price, amount)
def Update(self, close_price): #Update the assets
self.account['USDT']['unrealised_profit'] = 0
self.account['USDT']['hold'] = 0
self.account['USDT']['long'] = 0
self.account['USDT']['short'] = 0
for symbol in self.trade_symbols:
if not np.isnan(close_price[symbol]):
self.account[symbol]['unrealised_profit'] = (close_price[symbol] - self.account[symbol]['hold_price'])*self.account[symbol]['amount']
self.account[symbol]['price'] = close_price[symbol]
self.account[symbol]['value'] = self.account[symbol]['amount']*close_price[symbol]
if self.account[symbol]['amount'] > 0:
self.account['USDT']['long'] += self.account[symbol]['value']
if self.account[symbol]['amount'] < 0:
self.account['USDT']['short'] += self.account[symbol]['value']
self.account['USDT']['hold'] += abs(self.account[symbol]['value'])
self.account['USDT']['unrealised_profit'] += self.account[symbol]['unrealised_profit']
self.account['USDT']['total'] = round(self.account['USDT']['realised_profit'] + self.initial_balance + self.account['USDT']['unrealised_profit'],6)
self.account['USDT']['leverage'] = round(self.account['USDT']['hold']/self.account['USDT']['total'],3)
```
## Correlation Analysis to Filter Currencies
Correlation calculation is a method in statistics used to measure the linear relationship between two variables. The most commonly used correlation calculation method is the Pearson correlation coefficient. The following is the principle, formula and implementation method of correlation calculation. The Pearson correlation coefficient is used to measure the linear relationship between two variables, and its value range is between -1 and 1:
- 1 indicates a perfect positive correlation, where the two variables always change in sync. When one variable increases, the other also increases proportionally. The closer it is to 1, the stronger the correlation.
- -1 indicates a perfect negative correlation, where the two variables always change in opposite directions. The closer it is to -1, the stronger the negative correlation.
- 0 means no linear correlation, there is no straight line relationship between the two variables.
The Pearson correlation coefficient determines the correlation between two variables by calculating their covariance and standard deviation. The formula is as follows:
in which:
-  is the Pearson correlation coefficient between variables X and Y.
-  is the covariance of X and Y.
-  and
 are the standard deviations of X and Y respectively.
Of course, you don't need to worry too much about how it is calculated. You can use 1 line of code in Python to calculate the correlation of all currencies. The figure shows a correlation heat map. Red represents positive correlation, blue represents negative correlation, and the darker the color, the stronger the correlation. You can see that most of the area is dark red, so the positive correlation of digital currencies is very strong.
```
import seaborn as sns
corr = df_close.corr()
plt.figure(figsize=(20, 20))
sns.heatmap(corr, annot=False, cmap='coolwarm', vmin=-1, vmax=1)
plt.title('Correlation Heatmap of Cryptocurrency Closing Prices', fontsize=20);
```
Based on the correlation, the top 20 most correlated currency pairs are selected. The results are as follows. Their correlations are very strong, all above 0.99.
```
MANA SAND 0.996562
ICX ZIL 0.996000
STORJ FLOW 0.994193
FLOW SXP 0.993861
STORJ SXP 0.993822
IOTA ZIL 0.993204
SAND 0.993095
KAVA SAND 0.992303
ZIL SXP 0.992285
SAND 0.992103
DYDX ZIL 0.992053
DENT REEF 0.991789
RDNT MANTA 0.991690
STMX STORJ 0.991222
BIGTIME ACE 0.990987
RDNT HOOK 0.990718
IOST GAS 0.990643
ZIL HOOK 0.990576
MATIC FLOW 0.990564
MANTA HOOK 0.990563
```
The corresponding code is as follows:
```
corr_pairs = corr.unstack()
# Remove self-correlation (i.e. values on the diagonal)
corr_pairs = corr_pairs[corr_pairs != 1]
sorted_corr_pairs = corr_pairs.sort_values(kind="quicksort")
# Extract the top 20 most and least correlated currency pairs
most_correlated = sorted_corr_pairs.tail(40)[::-2]
print("The top 20 most correlated currency pairs are:")
print(most_correlated)
```
## Backtesting Verification
The specific backtest code is as follows. The demonstration strategy mainly observes the price ratio of two cryptocurrencies (IOTA and ZIL) and trades according to the changes in this ratio. The specific steps are as follows:
Initialization:
- Define trading pairs (pair_a = 'IOTA', pair_b = 'ZIL').
- Create an exchange object e with an initial balance of $10,000 and a transaction fee of 0.02%.
- Calculate the initial average price ratio avg.
- Set an initial transaction value value = 1000.
Iterate over price data:
- Traverse the price data at each time point df_close.
- Calculates the deviation of the current price ratio from the mean diff.
- The target transaction value is calculated based on the deviation aim_value, and one value is traded for every 0.01 deviation. Buying and selling operations are determined based on the current account position and price situation.
- If the deviation is too large, execute sell pair_a and buy pair_b operations.
- If the deviation is too small, buy pair_a and sell pair_b operations are performed.
Adjust the mean:
- Updates the average price ratio avg to reflect the latest price ratios.
Update accounts and records :
- Update the position and balance information of the exchange account.
- Record the account status at each step (total assets, held assets, transaction fees, long and short positions) to res_list.
Result output:
- Convert res_list to dataframe res for further analysis and presentation.
```
pair_a = 'IOTA'
pair_b = "ZIL"
e = Exchange([pair_a,pair_b], fee=0.0002, initial_balance=10000) #Exchange definition is placed in the comments section
res_list = []
index_list = []
avg = df_close[pair_a][0] / df_close[pair_b][0]
value = 1000
for idx, row in df_close.iterrows():
diff = (row[pair_a] / row[pair_b] - avg)/avg
aim_value = -value * diff / 0.01
if -aim_value + e.account[pair_a]['amount']*row[pair_a] > 0.5*value:
e.Sell(pair_a,row[pair_a],(-aim_value + e.account[pair_a]['amount']*row[pair_a])/row[pair_a])
e.Buy(pair_b,row[pair_b],(-aim_value - e.account[pair_b]['amount']*row[pair_b])/row[pair_b])
if -aim_value + e.account[pair_a]['amount']*row[pair_a] < -0.5*value:
e.Buy(pair_a, row[pair_a],(aim_value - e.account[pair_a]['amount']*row[pair_a])/row[pair_a])
e.Sell(pair_b, row[pair_b],(aim_value + e.account[pair_b]['amount']*row[pair_b])/row[pair_b])
avg = 0.99*avg + 0.01*row[pair_a] / row[pair_b]
index_list.append(idx)
e.Update(row)
res_list.append([e.account['USDT']['total'],e.account['USDT']['hold'],
e.account['USDT']['fee'],e.account['USDT']['long'],e.account['USDT']['short']])
res = pd.DataFrame(data=res_list, columns=['total','hold', 'fee', 'long', 'short'],index = index_list)
res['total'].plot(grid=True);
```
A total of 4 groups of currencies were backtested, and the results were ideal. The current correlation calculation uses future data, so it is not very accurate. This article also divides the data into two parts, based on the previous calculation of correlation and the subsequent backtest trading. The results are a little different but not bad. We leave it to the user to practice and verify.
## Potential Risks and Ways to Improve
Although the pair trading strategy can be profitable in theory, there are still some risks in actual operation: the correlation between currencies may change over time, causing the strategy to fail; under extreme market conditions, price deviations may increase, resulting in larger losses; the low liquidity of certain currencies may make transactions difficult to execute or increase costs; and the fees generated by frequent transactions may erode profits.
To reduce risks and improve the stability of strategies, the following improvement measures can be considered: regularly recalculate the correlation between currencies and adjust trading pairs in a timely manner; set stop loss and take profit points to control the maximum loss of a single transaction; trade multiple currency pairs at the same time to diversify risks.
## Conclusion
The digital currency pair trading strategy achieves profit by taking advantage of the correlation of currency prices and performing arbitrage operations when prices deviate. This strategy has high theoretical feasibility. A simple live trading strategy source code based on this strategy will be released later. If you have more questions or need further discussion, please feel free to communicate.

1,915,249 | Setting Up a Python Virtual Environment (venv) | Python virtual environments are a great way to manage dependencies for your projects. They allow you... | 0 | 2024-07-08T05:47:44 | https://dev.to/zobaidulkazi/setting-up-a-python-virtual-environment-venv-amj | bash, pip, python, tutorial | Python virtual environments are a great way to manage dependencies for your projects. They allow you to create isolated environments where you can install packages specific to a project without affecting your system-wide Python installation. This blog post will guide you through setting up a Python virtual environment using venv.
## Step-by-Step Guide
1. Install Python
First, ensure that Python is installed on your system. Most modern Linux distributions, including Ubuntu, come with Python pre-installed. You can check if Python is installed by running:
```bash
python3 --version
```
If Python is not installed, you can install it using:
```bash
sudo apt update
sudo apt install python3
```
2. Install python3-venv
To create a virtual environment, you need the python3-venv package. Install it using:
```bash
sudo apt update
sudo apt install python3-venv
```
3. Create a Virtual Environment
Choose a directory where you want to store your project and navigate to it. Then create a virtual environment using the following command:
```bash
python3 -m venv myenv
```
Here, myenv is the name of the virtual environment. You can name it anything you like.
4. Activate the Virtual Environment
To start using the virtual environment, you need to activate it. Run the following command:
```bash
source myenv/bin/activate
```
5. Install Packages
With the virtual environment activated, you can now install Python packages using pip. For example, to install the requests library, run:
```bash
pip install fastapi
```
The installed packages will be specific to this virtual environment.
6. Deactivate the Virtual Environment
When you are done working in the virtual environment, you can deactivate it by running:
```bash
deactivate
```
This will return you to the system's default Python environment.
7. Reactivate the Virtual Environment
Whenever you want to work on your project again, navigate to your project directory and activate the virtual environment:
```bash
source myenv/bin/activate
```
**Note:** This guide is written for Linux/Ubuntu systems. The commands may vary slightly for other operating systems.

1,915,250 | Step-by-Step Guide to Creating RESTful APIs with Node.js and PostgreSQL | Welcome to the world of building RESTful APIs with Node.js and PostgreSQL! In this guide, we'll take... | 0 | 2024-07-08T05:49:41 | https://dev.to/a_shokn/step-by-step-guide-to-creating-restful-apis-with-nodejs-and-postgresql-1k26 | webdev, javascript, postgres, node | Welcome to the world of building RESTful APIs with Node.js and PostgreSQL! In this guide, we'll take you on an exciting journey, where we'll transform your Node.js app into a robust, scalable RESTful API using PostgreSQL as our database. Let’s dive in and have some fun along the way!
Let’s start by setting up a new Node.js project.
```
mkdir node-postgres-api
cd node-postgres-api
npm init -y
```
We need a few packages to get our project up and running.
```
npm install express pg body-parser
```
1. Setting Up PostgreSQL
Fire up your PostgreSQL server and create a new database.
```
CREATE DATABASE node_postgres_api;
```
2. Creating the Database and Tables
Connect to your new database and create a simple users table.
```
CREATE TABLE users (
id SERIAL PRIMARY KEY,
name VARCHAR(100),
email VARCHAR(100) UNIQUE
);
```
3. Setting up an Express Server
Create a new file named server.js and set up a basic Express server.
```
const express = require('express');
const bodyParser = require('body-parser');
const app = express();
const port = 3000;
app.use(bodyParser.json());
app.listen(port, () => {
console.log(`Server running on port ${port}`);
});
```
4. Connecting to PostgreSQL
Now, let’s connect our server to the PostgreSQL database. Create a file named db.js.
```
const { Pool } = require('pg');
const pool = new Pool({
user: 'your_postgres_username',
host: 'localhost',
database: 'node_postgres_api',
password: 'your_postgres_password',
port: 5432,
});
module.exports = pool;
```
5.Creating API Endpoints
Let’s add some endpoints to our API. Update your server.js file.
```
const express = require('express');
const bodyParser = require('body-parser');
const pool = require('./db');
const app = express();
const port = 3000;
app.use(bodyParser.json());
// Get all users
app.get('/users', async (req, res) => {
try {
const result = await pool.query('SELECT * FROM users');
res.json(result.rows);
} catch (err) {
console.error(err.message);
}
});
// Get user by ID
app.get('/users/:id', async (req, res) => {
const { id } = req.params;
try {
const result = await pool.query('SELECT * FROM users WHERE id = $1', [id]);
res.json(result.rows[0]);
} catch (err) {
console.error(err.message);
}
});
// Create new user
app.post('/users', async (req, res) => {
const { name, email } = req.body;
try {
const result = await pool.query('INSERT INTO users (name, email) VALUES ($1, $2) RETURNING *', [name, email]);
res.json(result.rows[0]);
} catch (err) {
console.error(err.message);
}
});
// Update user
app.put('/users/:id', async (req, res) => {
const { id } = req.params;
const { name, email } = req.body;
try {
await pool.query('UPDATE users SET name = $1, email = $2 WHERE id = $3', [name, email, id]);
res.json('User updated successfully');
} catch (err) {
console.error(err.message);
}
});
// Delete user
app.delete('/users/:id', async (req, res) => {
const { id } = req.params;
try {
await pool.query('DELETE FROM users WHERE id = $1', [id]);
res.json('User deleted successfully');
} catch (err) {
console.error(err.message);
}
});
app.listen(port, () => {
console.log(`Server running on port ${port}`);
});
```
Congratulations! You’ve built a RESTful API with Node.js and PostgreSQL. Now you can expand this foundation with more features and complexity as needed. Happy coding!
Feel free to leave your thoughts or questions in the comments below. Let's keep the conversation going and make coding fun together!

1,915,253 | The Evolution and Readiness of Web3 Infra: Where Are We Now? | Innovations either prevail or perish! The statement is bold and insensitive but a reality,... | 0 | 2024-07-08T05:57:27 | https://www.zeeve.io/blog/the-evolution-and-readiness-of-web3-infra-where-are-we-now/ | web3 | <p>Innovations either prevail or perish! The statement is bold and insensitive but a reality, nonetheless. How? We have seen the likes of Nokia and BlackBerry perish to change because they were non-adaptive. However, Web3, despite being readily new, has acknowledged challenges and responded positively with time. As a result, from 2014 onwards, we have seen major industries inclining towards blockchains as their go-to strategy for improving their market share. In China and the United States, more than 300 companies featured on the Fortune 500 list have adopted blockchain. </p>
<p>So, if you think that the Bitcoin ETF's approval is out of the blue, that is not the case. It has happened due to structural evolution via infrastructural improvements Web 3 has embraced in this brief span of time since its inception. In this piece, we shall see some of the groundbreaking <a href="https://www.zeeve.io/web3-infrastructure-for-gaming/">Web 3 Infrastructure</a> readiness and evolution that is making blockchains native to adoption across a vast range of industries. </p>
<h2 class="wp-block-heading" id="h-the-evolution-period-outsmarting-the-learning-curve-nbsp">The Evolution Period: Outsmarting the Learning Curve </h2>
<p>Why are more industries ready to adopt the Web 3 way now than previously? The answer: Evolution. In the last 7 years starting 2018 onwards, we have seen some of the major upgrades coming to Web 3 in the form of; </p>
<p><strong>Infrastructure Improvements </strong></p>
<p>In the erstwhile set-up, we have already seen that there was a cookie-cutter approach to deploying blockchains. For example, enterprises had minimal options when it came to improvising on the communication with other blockchains or abstracting features by improving the tech infra that ideally impacts the gas costs, scalability, and UX . To put that into perspective, there was no scope to decouple the execution, consensus and settlement layers and make adjustments so that each can function independently to suit the specific application purpose. </p>
<p>However, as time passed, we witnessed improvements at the infrastructural fronts by the introduction of oracles that helped in fetching data from different blockchains. Along with this, to some extent, the intercommunication with other blockchains have improved massively by the introduction of bridges connecting different blockchains to some extent. Also, there was wallet integration to help improve the experience through account abstraction features that readily improved other aspects of the technology to optimize blockchain for peak level performance. </p>
<p><strong>Language</strong> </p>
<p>In the initial stage of the blockchains and smart-contracts, the coding part was the most crucial thing to crack. Why? Because, if you wanted to deploy smart-contracts, everything happened around Solidity. As a result, when you were deploying your application on top of the blockchain in the past, it had to be done from the scratch because RPC endpoint set-ups and others couldn’t be migrated from one language to another. However, the new era of Web 3 is increasingly different. Now you have Web 3 stacks that are using APIs to connect the Web 2 to Web 3. <a href="https://www.crossriver.com">Cross River Bank </a>is already doing the same by allowing banking institutions to use their existing technology stack to connect with the crypto sectors. </p>
<p><strong>Management </strong></p>
<p>Management of blockchains have also seen a massive transformation in the last couple of years. For example, blockchains consist of nodes, blocks, Consensus algorithms and miners responsible for taking the management in hand run operations. However, this process is readily complex and cost intensive. For setting up validators and others, an enterprise has to spend a lot of money initially. But citing the demand and dependency on blockchains increasing with time, now you have managed services that can allow you to set up your blockchains in just a click of a button on a rent based model. All of these evolutions have happened because increasing adoption has helped the technology to mature. Let’s see how the infrastructure readiness has occurred overtime. </p>
<h2 class="wp-block-heading" id="h-infrastructure-readiness-of-web-3-the-journey-of-innovation-over-time">Infrastructure Readiness of Web 3: The Journey of Innovation Over Time</h2>
<h3 class="wp-block-heading" id="h-ready-to-deploy-stack-for-operations-nbsp">Ready To Deploy Stack for Operations </h3>
<p>How did rubber tires replace the stone wheels so fast? They were standardized and ready for deployment without any omissions and commissions required at larger proportions. Likewise, the same is true for present-day Web 3. If you have to do everything from scratch, it would take centuries to truly hit mass adoption. However, those drawbacks fade when you have technologies which have matured overtime. Technologies that provide you with an already ready to deploy validators, governance, token and liquidity at your own will without having to change a single line of code. So, in the past, if your existing system was built on C++, Go, Java, or Python, it was impossible to set-up RPCs and query transcations. </p>
<p>However, appchains and rollups SDKs with the likes of Polygon CDK completely revolutionized this possibility. Now, you need not have to experience walled gardens when using blockchains like in the past. On the contrary, using SDKs like Polygon, you can bypass the struggle of adhering to a standardized proving system to setup your blockchain. Rather, the Polygon SDK stack allows enterprises to set up a value chain with Polygon as an existing chain or a new chain based on their will and that too without having to spend months on the development, instead the libraries are robust enough to allow drag and deploy deployment, which is comprehensive but quite different from what we have seen on Ethereum. </p>
<p>For example, there's the possibility of using a different chain as a settlement layer other than Ethereum. With that, Dapps have full control on governance, validators, tokens and liquidity using the robustness and readiness of ready to deploy stacks like Polygon CDK, ZySync, Cosmos SDK, or Arbitrum Orbit chains. </p>
<h3 class="wp-block-heading" id="h-highly-scalable-chains-nbsp">Highly Scalable Chains </h3>
<p>You can measure the readiness of a technology when it can accommodate the changing needs of the sector. In this regard, some of the rollup environments provided an added advantage over Ethereum, but they couldn’t match peak hyper scalability. For example, during a very high network clogging event, one some of the layer 2’s, we have seen fees touching $5 to $8 for every transaction. The erstwhile <a href="https://www.zeeve.io/blog/web3-explained-the-ultimate-beginners-guide/">Web 3</a> environment had very little room for improving the block space because in doing so, there’s a greater chance for diluting the decentralization. </p>
<p>But in the present context, we have seen stark improvements through parallel processing on StarkNet that introduces multi-tasking for rollups. So, in this model, transactions can be easily categorized in a specific order and opted for execution. </p>
<p>As you can see in the above image, someone seeking a Fanta to quench the thirst has to go with the pepsi guys in a queue, which is not needed in the first place for them. But when parallel processing comes, it breaks the process through a state-access parallelization model where the network would group the transaction and the RPC will feed the consensus system with a specific group of transcations representing different categorization; allowing faster finality. This could ideally improvise on chains like Polkadot, which are introducing . Hence, it simply stimulates the processing / TPS and significantly impacts the gas cost and too an extent, the scalability has put the present day Web 3 in line with Visa/mastercard to support a near equivalent financial ecosystem like CeDeFi, where Dapps can work with the traditional financial system like Visa/Mastercard to bring fiat onramps/offramps to Web3, which were impossible when we look into the past because blockchains could meet the speed as given in the image below. </p>
<h3 class="wp-block-heading" id="h-maturity-of-technology-in-zkp-op-and-fhe">Maturity of Technology In ZKP, OP, and FHE</h3>
<p>There cannot be an independent ecosystem as a standalone solution and we can expect to have 10% GDP moving to blockchains. For industries and enterprises to readily accept Web 3, it should be safe, private, secure and easily interoperable. In the past period of generation 1 blockchains, it was very difficult to secure interoperability, privacy, scalability and decentralization, because the technology stack was not ready for this leap. Fast forward to 2022 and beyond, we have seen massive level upgrades to roll-up stacks like Optimism, where through the use of the ZK-Technology, it has been possible to safeguard one’s data. On top of this, rollups like Optimism have provided a standardized way of modules or libraries of code to build a single environment for all the rollups to operate and excel. </p>
<p>In this way, in the past ideally blockchains were like massive walled gardens/islands of their own. However, through upgrades in the tech, now a superchain thesis of independent yet easily communicable blockchains is possible. FHE and ZK readiness have further upped the ante because privacy was a grave concern for roll ups that were using the Zk-Tech. But introduction of FHE concepts in roll ups brought forward through <a href="https://blockworks.co/news/fhenix-whitepaper-fhe-rollups">Fhenix</a>, a layer2 network, has made privacy, security, scalability and decentralization to all occur at once when optimistic rollups, ZKPs and FHE Rollups collectively work to not only improve scalability but without compromising the privacy. </p>
<h3 class="wp-block-heading" id="h-eliminating-the-gas-for-good-nbsp">Eliminating the Gas for Good </h3>
<p>Initially, when we speak of Bitcoin and the Ethereum Network, the nightmarish experience to behold was paying very high gas fees. In some situations, it could even surpass $10 to $100 or so. Why? Because, all the transaction data was stored as a call-data forever on the blockchains. However, ideally the need to keep the transaction is as good as may be till the time the fraud proofs are not challenged. </p>
<p>But in the absence of technology maturity, these transactions simply lived on the blockchains forever. However, the present maturity through EIP- 4844 introduces the concept of Blob-Data instead of call-data. So, multiple transactions can be kept as blobs for a specific time period and rolled as one single transaction after the challenger period ends and the blob space deletes that data to make space for new data to be injected as blobs. </p>
<p>Now, when this technology fuses with relayer function where a blockchain can reprogram the smart-contract through Account Abstraction (AA) to either eliminate the gas or pay gas share on a shared basis, it significantly makes chains either very low on gas or even gas free. </p>
<h3 class="wp-block-heading" id="h-simplifying-usage-through-superior-ux">Simplifying Usage Through Superior UX</h3>
<p>Using blockchains in 2016 Vs. 2024? What’s the difference, if you may ask? In 2016, the EOAs were not abstract. Now, EOAs can be abstracted as per the need. So, when you are speaking of improving the user-experience in 2016 to 2020, it was not possible because smart-contracts didn’t evolve to that level. But at present, you can abstract almost everything by eliminating the need to login every single time through wallets or setting up session keys for interaction with the blockchains. </p>
<p>In addition to this, you can also get away with the task of remembering those complex phrases and include programmability to abstract everything that is necessary. So, you can now define smart-contract programmability wallets that allow quick access through even social accounts or they can also aid in account recovery through the use of social media profiles and include any native token for use in gas payments. </p>
<h3 class="wp-block-heading" id="h-standardized-deployments-of-customized-chains-nbsp">Standardized Deployments of Customized Chains </h3>
<p>While developing an application on top of the blockchain, the approach that enterprises seek is short and time-boxed. Still, the experience that enterprises get is lengthy, breaking the bank in the process. However, that narrative is changing when R-a-a-S solutions come into play. Now, one can launch their own rollups or an app chain with just a click of a button. <a href="https://www.zeeve.io/rollups/">R-a-a-S service providers</a> have ended up as game changers where they have expedited the development time and pruned the development cost. How? Through providing a growing rollup infrastructure to launch applications, be it Web 3 games, deFi protocols, or others, with just a simple integration experience. </p>
<p>Now, enterprising entrepreneurs aspiring to launch on top of the blockchain need not have to think of everything from scratch, such as the consensus, execution, and settlement layer. Rather, they have the discretion to launch on DevNet to try different configurations; if things are good, they can move to testnet and, finally, the full-fledged mainnet. They can choose on/off-chain data availability, centralized/decentralized sequencers, and other crucial integrations, with 24/7 monitoring through a single dashboard, analytics, and alerts. R-a-a-S service providers like Zeeve have provided that advantage where enterprises can launch on their preferred tech stack like Optimism's OP Stack, Arbitrum Orbit, Polygon CDK, or zkSync ZK Stack with just a click of a button and see their blockchain going live very fast. </p>
<h3 class="wp-block-heading" id="h-more-powerful-amp-augmented-platforms">More Powerful & Augmented Platforms</h3>
<p>Some 7 to 8 years from now, Ethereum will be the single source of truth. You have to rely on it for execution, consensus, and settlement. Hence, if a single transaction finality was costing $100, it was no surprise at all. However, in the past seven years, adoption has skyrocketed, exposing numerous points of failure that need undivided attention. Data storage was the most important proposition to acknowledge. In this regard, powerful and augmented platforms like ALT DAs have become an amenable refuge. Why? Imagine competing for a block space to store your heavy transaction data amounting to 50 to 100 KB versus a proof size of compressed recursive data of thousands of transactions stored off-chain in a 10 KB or lesser proof size. If you ask if this was possible three years ago, it was not. Is it possible now? Of Course, allegiance to the ALT DA layers like Near, Celestia, Avail, and Eigen DA makes this possible. Now, you can save a lot of costs, as evidenced by the image below; </p>
<p>So, if you are witnessing a massive level where <a href="https://www.wipro.com/business-process/blockchain-adoption-for-enterprises-leapfrogging-towards-reality/#:~:text=Blockchain%20is%20clearly%20gaining%20incremental,phase%20of%20their%20blockchain%20journey.">28% </a>of the enterprises are leapfrogging into blockchain adoption and another 42% of them have been making up their minds, it is not because they are fomo-ing but because they have ideally identified and acknowledged the benefits that it can bring. That’s where the journey has come from being a technology meant for the nerds to a technology that is revolutionizing the future and changing the business landscape for better outcomes. That has been the evolution and the readiness of Web 3 to change the business dynamics of the future. </p>

Building a successful P2P crypto exchange requires an understanding of key components, technology and market dynamics. Here are ten important points to guide the development of P2P crypto exchanges.
**Understanding the basics of P2P exchanges
**P2P exchanges allow users to trade directly with each other. Unlike traditional exchanges that act as brokers, P2P platforms facilitate business by connecting buyers and sellers. This decentralized approach offers better privacy, lower fees and better security.
**Choose the right blockchain technology
**Choosing the right blockchain is essential for your P2P exchange. Bitcoin and Ethereum are popular choices due to their strong security and widespread adoption. Ethereum specifically supports smart contracts that can automate many processes in your exchange, ensuring transparency and trust.
**Develop a secure wallet
**A secure crypto wallet is the cornerstone of any P2P exchange. Users need a place to keep their digital assets safe. Integrating a trusted wallet with features like multi-signature authentication, cold storage, and two-factor authentication (2FA) increases user security and confidence.
**Implement strong security measures
**Security is paramount in P2P crypto exchanges. Implementation of end-to-end encryption, SSL certificates and DDoS protection help protect the platform from cyber threats. Regular security checks and updates are necessary to maintain a secure business environment.
**Create an intuitive user interface
**User experience can make or break your P2P exchange. A clean and intuitive interface ensures that users can easily navigate the platform. Features such as easy registration, user-friendly dashboards and simple business processes can significantly improve user satisfaction and engagement.
**Smart Contracts and Storage Services
**Smart contracts automate and track the terms of a contract between buyers and sellers. They can also act as backup services, holding money until both parties fulfill their obligations. This reduces the risk of fraud and increases trust in the community.
**Ensure liquidity
**Liquidity is crucial to the success of exchanges. This ensures that users can buy or sell assets quickly without significant price fluctuations. Working with liquidity providers or implementing liquidity can help maintain a stable and attractive business environment.
**Respect
**Respect for local and international regulations is essential. This includes meeting Anti-Money Laundering (AML) and Know Your Customer (KYC) requirements. Compliance with the rules will not only protect your exchange from legal problems, but also increase its credibility and credibility among users.
**Marketing and Community Building
**Attracting users to P2P exchanges requires effective marketing strategies. Use social media, search engine optimization and content marketing to reach potential users. Building a strong community through forums, social media and regular updates can foster loyalty and encourage more users to join your platform. 10. Continuous
**Improvement and Support
**The cryptocurrency market is dynamic and requires constant improvement to remain competitive. Update your platform regularly with new features, security enhancements and performance optimizations. Providing excellent customer support helps retain users and resolve issues quickly.

For many, exam dumps are synonymous with cheating or shortcuts to certification. However, this perception overlooks nuances and potential benefits that exam dumps can offer when used responsibly and ethically. In this article, we will delve deep into the topic, exploring what exam dumps are, addressing common misconceptions, and discussing their legitimate uses.
Understanding Exam Dumps
Exam dumps refer to collections of real exam questions that have been memorized, compiled, and shared by <a href="https://dumpsboss.com/">Exam Dumps</a> individuals who have recently taken the exam. These dumps are typically circulated online and are often accessed through specialized websites or forums. The allure of exam dumps lies in their promise to provide insight into actual exam questions and formats, thus potentially aiding preparation.
Common Misconceptions
Misconception #1: Exam Dumps are Always Illegal or Unethical
One of the primary criticisms leveled against exam dumps is their perceived role in promoting cheating. Critics argue that using exam dumps undermines the integrity of certification exams and devalues the effort put in by legitimate candidates. While it is true that using exam dumps to pass exams without proper understanding or preparation can be unethical, the legality and ethical considerations surrounding exam dumps are nuanced.
Misconception #2: Exam Dumps are Always Accurate and Reliable
Another prevalent misconception is that all exam dumps provide accurate and reliable information about the exam. In reality, the quality of exam dumps can vary significantly. Some dumps may contain outdated questions, incorrect answers, or misleading information. Relying solely on exam dumps without cross-referencing with official study materials can lead to misconceptions and inadequate preparation.
Misconception #3: Using Exam Dumps Guarantees Exam Success
There is a common belief that using exam dumps guarantees success in passing certification exams. However, success in exams depends on a combination of factors including understanding the subject matter, critical thinking skills, and familiarity with the exam format. Using exam dumps as a supplementary study aid rather than a shortcut is crucial for achieving genuine success.

1,915,257 | The Vital Importance of System Integration Testing (SIT) | In the complex network of today’s technology, where different applications link together to move... | 0 | 2024-07-08T06:02:12 | https://peakupdates.com/science-and-technology/the-vital-importance-of-system-integration-testing-sit | system, integration, testing | 
In the complex network of today’s technology, where different applications link together to move businesses ahead, system integration testing (SIT) becomes a very important step. SIT acts as an essential control point, making sure that the complicated workings of connected systems run smoothly and in agreement with each other. Although it is similar to other testing methods, what makes it unique is that it checks how different applications work together. Now, we will look at the main reasons why doing system integration testing is essential for companies.
**Verifying interoperability**
The main goal of SIT is to check if different programs can work together as one complete system. Now, with IT being so complicated, companies use many applications that each do a different job. SIT makes sure that these programs talk to each other well and share information without mistakes, like how in real life people use many systems at the same time.
**Seamless business process incorporation**
Companies change, and their ways of working change too. When they put a new ERP system into use or start using a CRM tool for managing customer relationships, these changes in how the business works need to be tested very carefully. SIT makes it easy to add these changes without interrupting the normal work processes and helps them fit with how things are already done.
**Mitigating disruptions from updates**
Updates for software are always necessary, sometimes because of correcting errors, adding new options or improving security. However, the impact of an update in a single program can spread through connected systems and might cause interruptions. SIT is very important for finding and reducing risks because it tests updates on applications that are connected. This way, companies can solve compatibility problems before they happen and keep their operations running smoothly.
**Enhancing data integrity**
In a linked system of nature, keeping data true and whole is very important. SIT checks if the data is correct, full, and stays the same when it goes between various programs. By carefully examining the transfer of data, SIT assists in protecting it from being corrupted, copied multiple times or getting lost, which helps to maintain the trustworthiness of important business information.
**Reducing time and cost overruns**
Finding and fixing problems with integration after putting the system to use can cost a lot of money and take much time. System integration testing works as an early step, spotting possible troubles soon in the process of creating when it is simpler and less costly to solve them. Businesses can reduce the chance of expensive delays and make sure that moving to production settings happens more smoothly by taking care of integration difficulties before they happen.
**Boosting customer satisfaction**
In the end, when different systems work together without problems, it makes a better experience for the user. This is true if we are talking about people inside the company using business tools or outside customers who use online services. SIT helps to make sure that these systems run well and without interruptions. By providing a smooth experience for users, companies can create loyal customers and achieve an advantage over competitors in the marketplace.
To sum up, system integration testing (SIT) is very important for strong software development because it makes sure that connected systems work well together without problems. As companies deal with the difficult changes in digital technology, it is essential to use SIT to reduce risks, make operations more reliable and provide better experiences for users.

Then print the respective minimum and maximum values as a single line of two space-separated long integers.
**Example**
arr=[1,3,5,7,9]
The minimum sum is 1+3+5+7 = 16 and the maximum sum is 3+5+7+9 = 24. The function prints 16 24.
We will be discussing two methods to solve this;
one is using the sort() method.
Here in the above method the time complexity will be "O(nlogn)" due to sort() method. To make the time complexity better, the optimized code is given below.

In this blog post, we will see how to analyze the logs generated by the system.
🫱🫱🫱🫱[Let's build a production-ready logger using Winston](https://dev.to/naineel12/lets-build-a-production-ready-logger-using-winston-oo4)🫲🫲🫲🫲
While many advanced tools are available for log analysis, such as the ELK stack and Splunk, we will see how to do it the lame way using JavaScript🥱🥱.
## The Log Format
The logs generated by the logger are in the following format:
### Understanding The Log Format
The log format includes the following fields:
- `timestamp`: The time at which the log was generated
- `level`: The log level (DEBUG, INFO, WARN, ERROR)
- `Source IP`: The IP address of the source of the client making the request
- `kind of request`: The kind of request made by the client (GET, POST, PUT, DELETE)
- `response time`: The time taken by the server to respond to the request
- `path`: The path of the request made by the client
- `status code`: The status code of the response sent by the server
- `response time`: The time taken by the server to respond to the request
- `total time`: The total time taken by the server to process the request
- `Remote IP`: The IP address of the client making the request
## The Log Analyzer
### Laying The Basis For The Log Analyzer
First, create a regular expression to parse the log format.
```javascript
const logLevelPattern = /(?<date>\d{4}-\d{2}-\d{2})\s+(?<time>\d{2}:\d{2}:\d{2})\s+(?<level>\w+):\s+(?<client_ip>::ffff:\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}|::1)\s+(?<method>\w+)\s+(?<path>\/\S*)\s+(?<status>\d{3})\s+(?<response_time_1>\d+\.\d{3})\s+ms\s+(?<response_time_2>\d+\.\d{3})\s+ms\s+(?<other_ip>::ffff:\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}|::1)/g;
```
The regular expression seems daunting at first sight, but it's not that hard to understand. It consists of named groups for each field in the log format. The named groups are enclosed in `(?<name>pattern)`.
Using named groups makes it easier to extract the fields from the log line. For example, to extract the `level` field from the log line, we can use the following code:
```javascript
const logLine = '2024-07-04 10:42:09 error: ::ffff:72.200.26.133 GET /api/v1/resource 201 0.082 ms 0.177 ms ::ffff:72.200.26.133';
const match = logLevelPattern.matchAll(logLine);
for (const m of match) {
//We are interested in the groups from the match object because we have used named groups in the regex.
console.log(m.groups);
console.log(m.groups.level);
}
```
The `match` object will have this kind of output:
The `groups` property of the match object will have the named groups extracted from the log line. We can access the `level` field using `m.groups.level`.
### Analyzing The Logs Using The Log Analyzer
Now that we have the regular expression to parse the log format, let's create a log analyzer that reads the logs from a file and analyzes them.
```javascript
import { EventEmitter } from 'events';
import fs from 'fs';
import path from 'path';
class LogAnalyzer extends EventEmitter {
// initialize the log analyzer with the log file stream and the log level pattern and initialize the objects to store the analysis results
constructor(logFileStream, logLevelPattern) {
super();
this.logFileStream = logFileStream;
this.logLevelPattern = logLevelPattern;
this.time = {};
this.paths = {};
this.ips = {};
this.responseTime = [];
this.totalResponseTime = [];
this.count = 0;
}
//method to start the analysis
analyze() {
this.logFileStream.on('ready', () => console.log('================START======================='));
this.logFileStream.on('data', this.processChunk.bind(this));
this.logFileStream.on('end', this.finishAnalysis.bind(this));
}
//method to process each chunk of data read from the log file
processChunk(chunk) {
console.log('Processing chunk:', this.count);
this.logFileStream.pause();
const output = chunk.toString().matchAll(this.logLevelPattern);
for (const match of output) {
//extract the named groups from the match object
const { groups } = match;
//update the objects with the extracted fields
this.updateObjects(groups);
}
this.count++;
this.logFileStream.resume();
}
//method to update the objects with the extracted fields
updateObjects(groups) {
const hourKey = groups.time.split(':')[0] + ':00';
this.time[hourKey] = (this.time[hourKey] || 0) + 1;
this.updateObject(this.paths, groups.path);
this.updateObject(this.ips, groups.client_ip);
this.responseTime.push(parseFloat(groups.response_time_1));
this.totalResponseTime.push(parseFloat(groups.response_time_2));
}
//method to update an object with a key
updateObject(obj, key) {
obj[key] = (obj[key] || 0) + 1;
}
//method to finish the analysis
finishAnalysis() {
console.log('================END=========================');
console.log("Let's perform some analysis on the log file");
this.emit('analysisComplete', this.getAnalysisResults());
}
//method to sort an object based on the count of the keys
sortingObject(obj, max = true) {
//sorting is based on the count of the keys to get the most used or least used keys
if (max) {
return Object.entries(obj).sort((a, b) => b[1] - a[1]);
} else {
return Object.entries(obj).sort((a, b) => a[1] - b[1]);
}
}
//method to get the analysis results
getAnalysisResults() {
return {
timeDistribution: this.sortingObject(this.time, true).slice(0, 4),
mostUsedPathDistribution: this.sortingObject(this.paths, true).slice(0, 4),
leastUsedPathDistribution: this.sortingObject(this.paths, false).slice(0, 4),
ipDistribution: this.sortingObject(this.ips, true).slice(0, 4),
avgResponseTime: this.average(this.responseTime).toFixed(5),
avgTotalResponseTime: this.average(this.totalResponseTime).toFixed(5),
};
}
average(arr) {
return arr.reduce((a, b) => a + b, 0) / arr.length;
}
}
// Usage:
const logLevelPattern = /(?<date>\d{4}-\d{2}-\d{2})\s+(?<time>\d{2}:\d{2}:\d{2})\s+(?<level>\w+):\s+(?<client_ip>::ffff:\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}|::1)\s+(?<method>\w+)\s+(?<path>\/\S*)\s+(?<status>\d{3})\s+(?<response_time_1>\d+\.\d{3})\s+ms\s+(?<response_time_2>\d+\.\d{3})\s+ms\s+(?<other_ip>::ffff:\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}|::1)/g;
const logFileStream = fs.createReadStream(path.resolve('./logs/combined/generated_logs.log'), {
encoding: 'utf-8',
highWaterMark: 10 * 1024, // 10KB
});
const analyzer = new LogAnalyzer(logFileStream, logLevelPattern);
analyzer.on('analysisComplete', (results) => {
console.log('Analysis complete. Results:', results);
});
analyzer.analyze();
```
**Workflow**:
- The `logFileStream` is created using `fs.createReadStream` to read the log file in chunks.
- The `LogAnalyzer` class is created with the `logFileStream` and `logLevelPattern` as arguments.
- The `analyze` method is called on the `LogAnalyzer` instance to start the analysis.
- The `processChunk` method is called when a chunk of data is read from the log file. It processes the chunk and extracts the fields from the log line using the `logLevelPattern`.
- In the `processChunk` method, `updateObjects` is called to update the objects with the extracted fields.
- The `finishAnalysis` method is called when the analysis is complete. It emits an event `analysisComplete` with the analysis results.
- The `sortingObject` method is used to sort the objects based on the count of the keys.
- The `getAnalysisResults` method returns the analysis results.
- The `average` method calculates the average of an array of numbers.
- The `analysisComplete` event is listened to and the analysis results are logged to the console.
- The `analyze` method is called to start the analysis.
The `LogAnalyzer` class reads the log file in chunks and processes each chunk to extract the fields from the log line. It updates the objects with the extracted fields and calculates the average response time and total response time. Finally, it emits an event `analysisComplete` with the analysis results.
The analysis results include the time distribution, most used path distribution, least used path distribution, IP distribution, average response time, and average total response time.
**Output**:
This way we can analyze the logs generated by the logger using the log analyzer in an absolutely lame way😂😂

## Generating random logs
Let's address the elephant in the room: not everyone has a log file from a real production system to analyze. So, let's generate some random logs using the `faker` library.
[fakerjs documentation](https://fakerjs.dev/api/)
```javascript
import fs from 'fs';
import { faker } from '@faker-js/faker';
// Sample data
const methods = ["GET", "POST", "PUT", "DELETE"];
const paths = ["/", "/api/v1/resource", "/login", "/register"];
const ips = ['45.94.188.156', '238.249.31.148', '91.113.1.90', '113.232.207.105', '96.129.247.250', '105.171.179.234', '144.42.125.14', '109.111.74.178', '72.200.26.133', '83.65.134.149'];
const statusCodes = [200, 201, 400, 404, 500];
const levels = ["info", "error", "warn", "debug"];
// Function to generate a random timestamp
const randomTimestamp = (start, end) => {
const startDate = start.getTime();
const endDate = end.getTime();
return new Date(startDate + Math.random() * (endDate - startDate));
};
// Generate log entries
const logEntries = [];
const startDate = new Date(2024, 6, 4, 10, 41, 0); // Months are 0-based in JavaScript
const endDate = new Date(2024, 6, 4, 10, 45, 0);
for (let i = 0; i < 1000; i++) { // Generate 500 log entries
//Generating random log entries
const timestamp = randomTimestamp(startDate, endDate);
const dateStr = timestamp.toISOString().replace('T', ' ').substring(0, 19);
const level = faker.helpers.arrayElement(levels);
const clientIp = faker.helpers.arrayElement(ips);
const method = faker.helpers.arrayElement(methods);
const path = faker.helpers.arrayElement(paths);
const status = faker.helpers.arrayElement(statusCodes);
const responseTime1 = (Math.random() * (0.1 - 0.05) + 0.05).toFixed(3);
const responseTime2 = (Math.random() * (0.3 - 0.1) + 0.1).toFixed(3);
const otherIp = faker.helpers.arrayElement(ips);
logEntries.push(`${dateStr} ${level}: ::ffff:${clientIp} ${method} ${path} ${status} ${responseTime1} ms ${responseTime2} ms ::ffff:${otherIp}`);
}
// Write to log file
fs.writeFileSync('./logs/combined/generated_logs.log', logEntries.join('\n'));
console.log("Log file generated successfully.");
```
This script generates 1000 random log entries and writes them to a log file `generated_logs.log`. The log entries are generated with random timestamps, log levels, client IPs, methods, paths, status codes, response times, and other IPs.
You can find the complete code for generating random logs [here](https://github.com/naineel1209/winston-logger/blob/master/generator.js)
## Conclusion
In this blog post, we saw how to analyze the logs generated by the logger using the log analyzer. We created a log analyzer that reads the logs from a file, parses the log format, and analyzes the logs. We also generated random logs using the `faker` library to test the log analyzer.
While the log analyzer is a simple way to analyze logs, it is not suitable for large log files or real-time log analysis. For large log files or real-time log analysis, you can use advanced log analysis tools like ELK stack, Splunk, etc. But for small log files or testing purposes, the log analyzer is a good starting point.

## Introduction
In the modern digital landscape, privacy and security are paramount. Secure Multi-Party Computation (SMPC) is a cryptographic protocol that allows multiple parties to jointly compute a function over their inputs while keeping those inputs private. This technology has vast applications, including privacy-preserving data analysis and secure voting systems. In this blog, we'll explore how to implement SMPC using Node.js, making it simple and easy to understand with real-world examples.
What is Secure Multi-Party Computation (SMPC)?
SMPC is a subfield of cryptography that enables parties to collaboratively compute a function over their inputs without revealing those inputs to each other. The goal is to ensure that no single party can learn anything about the other parties' inputs beyond what can be inferred from their own input and the output.
## Why Use SMPC?
**Privacy:** Ensures that sensitive data remains confidential.
**Security:** Prevents unauthorized access and tampering.
**Collaboration:** Enables secure collaboration between entities without needing to share raw data.
## Problems Solved by Secret Sharing
Secret sharing addresses several critical issues:
**1. Data Confidentiality:** By splitting a secret into multiple shares, secret sharing ensures that no single participant holds enough information to reconstruct the secret. This prevents unauthorized access to sensitive data.
**2. Fault Tolerance:** Secret sharing can be designed so that the loss of some shares does not prevent the reconstruction of the secret. This adds robustness to the system.
**3. Distributed Trust:** Instead of placing trust in a single entity, secret sharing distributes trust across multiple participants. This mitigates the risk of a single point of failure or corruption.
## Example Without Secret Sharing: Security Vulnerabilities
Imagine a scenario where multiple companies need to collaboratively analyze their combined sales data to identify market trends. Without secret sharing, they might be tempted to share their raw sales data with each other. This approach has several security vulnerabilities:
**1. Data Exposure:** Sharing raw data exposes sensitive information. A malicious party could misuse this data for competitive advantage or sell it to third parties.
**2. Single Point of Failure:** If one company fails to protect the shared data, the entire dataset is compromised. A security breach in one company could expose all participants' data.
**3. Lack of Accountability:** It's challenging to ensure that all parties handle the data securely and responsibly. Mismanagement or malicious intent by one participant can jeopardize the entire collaboration.
## Getting Started with SMPC in Node.js
We'll be using the secret-sharing library, which simplifies implementing SMPC in JavaScript. This library provides tools for secret sharing and reconstruction.
### Step 1: Setting Up Your Environment
First, let's set up a basic Node.js environment.
**1. Install Node.js:** If you haven't already, download and install Node.js from [nodejs.org](https://nodejs.org/en)
**2. Initialize a Project:** Create a new directory for your project and initialize a new Node.js project.
```js
mkdir smpc-nodejs
cd smpc-nodejs
npm init -y
```
**3. Install the secret-sharing Library:**
```js
npm install secret-sharing
```
### Step 2: Implementing Secret Sharing
Secret sharing is a method used in SMPC to divide a secret into multiple parts (shares), which are then distributed to participants. Only a subset of these shares is needed to reconstruct the original secret.
Here's a simple example of secret sharing in JavaScript:
```js
const secretSharing = require('secret-sharing');
// Define the secret and number of shares
const secret = "mySuperSecret";
const numberOfShares = 5;
const threshold = 3; // Number of shares needed to reconstruct the secret
// Generate the shares
const shares = secretSharing.share(secret, numberOfShares, threshold);
console.log("Generated Shares:");
console.log(shares);
```
### Step 3: Reconstructing the Secret
To reconstruct the secret, you need at least the threshold number of shares.
```js
// Assume we have received 3 shares
const receivedShares = shares.slice(0, threshold);
// Reconstruct the secret
const reconstructedSecret = secretSharing.combine(receivedShares);
console.log("Reconstructed Secret:");
console.log(reconstructedSecret);
```
### Step 4: Real-World Example - Secure Voting System
Let's build a simple secure voting system using SMPC. In this example, each participant will cast their vote, and the final tally will be computed without revealing individual votes.
**1. Vote Sharing:**
```js
const votes = ["A", "B", "A", "C", "A"];
const voteShares = votes.map(vote => secretSharing.share(vote, numberOfShares, threshold));
console.log("Vote Shares:");
console.log(voteShares);
```
**2. Secure Tallyin **
```js
// Collect shares from participants
const collectedShares = voteShares.map(shares => shares.slice(0, threshold));
// Reconstruct votes
const reconstructedVotes = collectedShares.map(shares => secretSharing.combine(shares));
// Count votes
const voteCount = reconstructedVotes.reduce((acc, vote) => {
acc[vote] = (acc[vote] || 0) + 1;
return acc;
}, {});
console.log("Vote Count:");
console.log(voteCount);
```
## Conclusion
Implementing SMPC in Node.js can significantly enhance the privacy and security of your applications. By using the secret-sharing library, we've demonstrated how to perform secret sharing, reconstruct secrets, and build a simple secure voting system. As data privacy concerns continue to grow, leveraging SMPC in your projects can provide robust solutions to safeguard sensitive information.

1,915,271 | Art of SVG Animation | 10 Techniques Every UI Developer Should Master | SVGs (Scalable Vector Graphics) offer a modern way to enhance web and application interfaces with... | 0 | 2024-07-08T06:18:55 | https://dev.to/nnnirajn/art-of-svg-animation-10-techniques-every-ui-developer-should-master-3bkh | css, ui, animation, beginners | SVGs (Scalable Vector Graphics) offer a modern way to enhance web and application interfaces with high-quality, scalable graphics. Unlike traditional bitmap graphics, SVGs are made up of vector data, which means they can scale to any size without losing quality. This scalability makes SVGs immensely popular among UI developers looking to create dynamic, responsive, and visually appealing designs.
In this blog post, we will delve deep into the world of SVG animations. Whether you're a beginner looking to explore this exciting area or an experienced developer aiming to refine your skills, this guide will walk you through ten different methods to animate SVGs with practical code examples. By the end, you'll be ready to implement these techniques in your projects, elevating your UI designs to the next level.
#### Why Animate SVGs?
Before we jump into the specific methods, it's worth understanding why SVG animations are so beneficial:
**Resolution Independence**: SVGs look crisp at any screen density, which is crucial for supporting varied device resolutions.
**Small File Sizes**: Compared to many bitmap formats, SVGs typically have smaller file sizes, especially when animations involve simple geometric shapes and limited colors.
**Manipulability**: SVGs can be manipulated through CSS and JavaScript, providing flexibility in how animations are implemented and controlled.
**Accessibility**: Text inside SVGs remains selectable and searchable, enhancing usability and accessibility.
---
### Method 1: CSS Transitions
One of the simplest ways to begin animating an SVG is by using CSS transitions. CSS transitions allow you to change SVG properties smoothly over a specified duration.
**Example: Rotating a Gear**
Imagine you have an SVG of a gear. You want this gear to rotate continuously to signify a process or loading state.
```html
<svg viewBox="0 0 100 100">
<path id="gear" d="M50 30 L70 ... Z" fill="grey"/>
</svg>
```
```css
#gear {
transition: transform 2s linear infinite;
}
#gear:hover {
transform: rotate(360deg);
}
```
In the CSS, we specify that the `transform` property of the gear should transition over two seconds linearly and infinitely. When a user hovers over the gear, it rotates 360 degrees.
---
### Method 2: CSS Keyframes
For more complex animations, CSS keyframes provide the control you need. Keyframes allow you to define the property values at various stages of the animation.
**Example: Pulsating Circle**
Let's animate a circle to pulsate, growing and shrinking continuously.
```html
<svg viewBox="0 0 100 100">
<circle cx="50" cy="50" r="30" fill="blue"/>
</svg>
```
```css
@keyframes pulse {
0%, 100% {
r: 30;
}
50% {
r: 40;
}
}
circle {
animation: pulse 2s infinite;
}
```
Here, `@keyframes` defines a pulse animation where the radius (r) of the circle changes.
---
### Method 3: SVG SMIL Animations
SMIL (Synchronized Multimedia Integration Language) is an XML-based language that enables complex animations directly within SVG files.
**Example: Moving Along Path**
Imagine animating an object to move along a predefined path.
```html
<svg viewBox="0 0 100 100">
<path id="path" d="M10,10 Q50,50,90,10" fill="transparent" stroke="black"/>
<circle cx="10" cy="10" r="5" fill="red">
<animateMotion dur="4s" repeatCount="infinite" path="M10,10 Q50,50,90,10"/>
</circle>
</svg>
```
The circle moves along the curve defined by `path`, thanks to the `animateMotion` element.
---
### Method 4: JavaScript Libraries (GreenSock)
Many JavaScript libraries, like GreenSock (GSAP), facilitate complex SVG animations. GSAP is highly performant and works across all major browsers.
**Example: Bouncing Ball**
Here’s how you could create a bouncing ball animation using GSAP:
```html
<svg viewBox="0 0 100 100">
<circle id="ball" cx="50" cy="50" r="10" fill="green"/>
</svg>
```
```javascript
gsap.to("#ball", {
y: 60,
duration: 1,
ease: "bounce.out",
repeat: -1,
yoyo: true
});
```
The ball bounces continuously with `yoyo` effect that makes it move back and forth.
---
### Method 5: JavaScript and CSS Variables
Using JavaScript alongside CSS variables (custom properties) can make SVG animations responsive to user interactions or other dynamic conditions.
**Example: Color Shift**
Suppose you want the fill color of an SVG element to change based on cursor position.
```html
<svg viewBox="0 0 100 100">
<circle cx="50" cy="50" r="30" fill="var(--color, blue)"/>
</svg>
```
```javascript
document.addEventListener("mousemove", function(e) {
const color = e.clientX > window.innerWidth / 2 ? 'red' : 'blue';
document.documentElement.style.setProperty('--color', color);
});
```
Here, the color of the circle changes as the mouse moves horizontally across the screen.
---
### Method 6: SVG Filters for Animation
SVG filters are powerful tools for applying complex visual effects to SVG elements through animations.
**Example: Blur Effect**
An animated blur effect can create a sense of motion or change.
```html
<svg viewBox="0 displaced data #0 ]] 0interpretation of context and technical accuracy in generating content by enabling capability650">
<defs>
<filter id="blurEffect">
<feGaussianBlur in="SourceGraphic" stdDeviation="0"/>
</filter>
</defs>
<circle cx="50" cy="50" r="30" filter="url(#blurEffect)" fill="orange"/>
</svg>
```
```css
@keyframes blur {
from {
stdDeviation: 0;
}
to {
stdDeviation: 5;
}
}
circle {
animation: blur 8s infinite alternate;
}
```
In this animation, the circle blurs and unblurs smoothly, drawing attention while providing a dynamic visual effect.
---
### Example: Revealing Text
Text can be progressively revealed using an animated clipping path.
```html
<svg viewBox="0 0 100 100">
<defs>
<clipPath id="clip">
<rect x="0" y="0" width="0" height="100"/>
</clipPath>
</defs>
<text x="10" y="50" clip-path="url(#clip)">Hello!</text>
</svg>
```
```css
@keyframes reveal {
from {
width: 0;
}
to {
width: 100;
}
}
rect {
animation: reveal 5s forwards;
}
```
The text `Hello!` is gradually revealed from left to right.
---
### Method 8: Morphing Shapes
Shape morphing can be achieved using several libraries and native SVG features, creating seamless transitions between different forms.
**Example: Heart to Circle Morph**
A common example is morphing a heart shape into a circle.
```html
<svg viewBox="0 0 100 100">
<!-- Add path for heart and circle -->
</svg>
```
```css
/* Add keyframes for morphing */
```
Using libraries like `flubber` or even CSS, the paths' "d" attribute is interpolated between the heart and the circle shapes.
---
### Method 9: Animated Gradients
Gradients in SVG can also be animated, useful for vibrant backgrounds or eye-catching elements.
**Example: Gradient Background Animation**
An animated radial gradient that shifts colors can serve as a dynamic background.
```html
<svg width="100%" height="100%">
<rect width="100%" height="100%">
<animate attributeName="fill" values="radial-gradient(circle, red, yellow); radial-gradient(circle, yellow, green); radial-gradient(circle, green, blue);" dur="10s" repeatCount="infinite"/>
</rect>
</svg>
```
This rectangle's fill smoothly transitions across a spectrum of colors, creating a lively background effect.
---
### Example: Interactive Color Change
A simple interaction where the SVG changes color on click.
```html
<svg viewBox="0 0 100 100" onclick="changeColor()">
<circle cx="50" cy="50" r="30" fill="purple"/>
</svg>
```
function change HUGE database with sample codes, based on story telling
button, and a subscription-based panel.BUTTON TEXT HERE JavaScript.
```javascript
document.querySelector('svg').addEventListener('click', function() {
this.querySelector('circle').setAttribute('fill', 'pink');
});
```
By clicking on the SVG, the fill color of the circle changes to pink, demonstrating a simple interactive animation.
### Conclusion
SVG animations open up a vast array of possibilities for making your UIs more attractive and engaging. From simple CSS transitions to interactive JavaScript-powered animations, each method offers unique benefits and capabilities. Experimenting with various techniques and understanding their implications on performance and browser compatibility is key to mastering SVG animations. Whether enhancing the user experience or simply adding visual flair, these ten methods provide a solid foundation for any UI developer looking to dive into the world of SVG animations. | nnnirajn |

1,915,300 | Apache Doris for log and time series data analysis in NetEase, why not Elasticsearch and InfluxDB? | For most people looking for a log management and analytics solution, Elasticsearch is the go-to... | 0 | 2024-07-08T06:36:09 | https://dev.to/apachedoris/apache-doris-for-log-and-time-series-data-analysis-in-netease-why-not-elasticsearch-and-influxdb-5f60 | datascience, database, dataengineering, opensource | For most people looking for a log management and analytics solution, Elasticsearch is the go-to choice. The same applies to InfluxDB for time series data analysis. These were exactly the choices of NetEase, one of the world's highest-yielding game companies but more than that. As NetEase expands its business horizons, the logs and time series data it receives explode, and problems like surging storage costs and declining stability come. As NetEase's pick among all big data components for platform upgrades, [Apache Doris](https://doris.apache.org) fits into both scenarios and brings much faster query performance.
We list the gains of NetEase after adopting Apache Doris in their monitoring platform and time series data platform, and share their best practice with users who have similar needs.
## Monitoring platform: Elasticsearch -> Apache Doris
NetEase provides a collaborative workspace platform that combines email, calendar, cloud-based documents, instant messaging, and customer management, etc. To oversee its performance and availability, NetEase builds the Eagle monitoring platform, which collects logs for analysis. Eagle was supported by Elasticsearch and Logstash. The data pipeline was simple: Logstash gathers log data, cleans and transforms it, and then outputs it to Elasticsearch, which handles real-time log retrieval and analysis requests from users.
Due to NetEase's increasingly sizable log dataset, Elastisearch's index design, and limited hardware resources, the monitoring platform exhibits **high latency** in daily queries. Additionally, Elasticsearch maintains high data redundancy for forward indexes, inverted indexes, and columnar storage. This adds to cost pressure.
After migration to Apache Doris, NetEase achieves a 70% reduction in storage costs and an 11-fold increase in query speed.
- **70% reduction in storage costs**: This means a dataset that takes up 100TB in Elasticsearch only requires 30TB in Apache Doris. Moreover, thanks to the much-reduced storage space usage, they can replace their HDDs with more expensive SSDs for hot data storage to achieve higher query performance while staying within the same budget.
- **11-fold increase in query speed**: Apache Doris can deliver faster queries while consuming less CPU resources than Elasticsearch. As shown below, Doris has reliably low latency in queries of various sizes, while Elasticsearch demonstrates longer latency and greater fluctuations, and the smallest speed difference is 11-fold.
## Time series data platform: InfluxDB -> Apache Doris
NetEase is also an instant messaging (IM) PaaS provider. To support this, it builds a data platform to analyze time series data from their IM services. The platform was built on InfluxDB, a time series database. Data flowed into a Kafka message queue. After the fields were parsed and cleaned, they arrived in InfluxDB, ready to be queried. InfluxDB responded to both online and offline queries. The former was to generate metric monitoring reports and bills in real time, and the latter was to batch analyze data from a day ago.
This platform was also challenged by the increasing data size and diversifying data sources.
- **OOM**: Offline data analysis across multiple data sources was putting InfluxDB under huge pressure and causing OOM errors.
- **High storage costs**: Cold data took up a large portion but it was stored the same way as hot data. That added up to huge expenditures.
Replacing InfluxDB with Apache Doris has brought higher cost efficiency to the data platform:
- **Higher throughput**: Apache Doris maintains a writing throughput of 500MB/s and achieves a peak writing throughput of 1GB/s. With InfluxDB, they used to require 22 servers for a CPU utilization rate of 50%. Now, with Doris, it only takes them 11 servers at the same CPU utilization rate. That means Doris helps cut down resource consumption by half.
- **67% less storage usage***: The same dataset used 150TB of storage space with InfluxDB but only took up 50TB with Doris. Thus, Doris helps reduce storage costs by 67%.
- **Faster and more stable query performance**: The performance test was to select a random online query SQL and run it 99 consecutive times. As is shown below, Doris delivers generally faster response time and maintains stability throughout the 99 queries.
## Best practice
Adopting a new product and putting it into a production environment is, after all, a big project. The NetEase engineers came across a few hiccups during the journey, and they are kind enough to share about how they solved these problems and save other users some detours.
### Table creation
Table schema design has a significant impact on database performance, and this holds for log and time series data processing as well. Apache Doris provides optimization options for these scenarios. These are some recommendations provided by NetEase.
1. **Retrieval of the latest N logs**: Using a `DATETIME` type time field as the primary key can largely speed queries up.
2. **Partitioning strategy**: Use `PARTITION BY RANGE` based on a time field and enable [dynamic partition](https://doris.apache.org/docs/2.0/table-design/data-partition#dynamic-partition). This allows for auto-management of data partitions.
3. **Bucketing strategy**: Adopt random bucketing and set the number of buckets to roughly three times the total number of disks in the cluster. (Apache Doris also provides an [auto bucket](https://doris.apache.org/docs/2.0/table-design/data-partition/#auto-bucket) feature to avoid performance loss caused by improper data sharding.)
4. **Indexing**: Create indexes for frequently searched fields to improve query efficiency. Pay attention to the parser for the fields that require full-text searching, because it determines query accuracy.
5. **Compaction**: Optimize the compaction strategies based on your own business needs.
6. **Data compression**: Enable `ZSTD` for better a higher compression ratio.
```sql
CREATE TABLE log
(
ts DATETIME,
host VARCHAR(20),
msg TEXT,
status INT,
size INT,
INDEX idx_size (size) USING INVERTED,
INDEX idx_status (status) USING INVERTED,
INDEX idx_host (host) USING INVERTED,
INDEX idx_msg (msg) USING INVERTED PROPERTIES("parser" = "unicode")
)
ENGINE = OLAP
DUPLICATE KEY(ts)
PARTITION BY RANGE(ts) ()
DISTRIBUTED BY RANDOM BUCKETS 250
PROPERTIES (
"compression"="zstd",
"compaction_policy" = "time_series",
"dynamic_partition.enable" = "true",
"dynamic_partition.create_history_partition" = "true",
"dynamic_partition.time_unit" = "DAY",
"dynamic_partition.start" = "-7",
"dynamic_partition.end" = "3",
"dynamic_partition.prefix" = "p",
"dynamic_partition.buckets" = "250"
);
```
### Cluster configuration
**Frontend (FE) configuration**
```sql
# For higher data ingestion performance:
enable_single_replica_load = true
# For more balanced tablet distribution:
enable_round_robin_create_tablet = true
tablet_rebalancer_type = partition
# Memory optimization for frequent imports:
max_running_txn_num_per_db = 10000
streaming_label_keep_max_second = 300
label_clean_interval_second = 300
```
**Backend (BE) configuration**
```SQL
write_buffer_size=1073741824
max_tablet_version_num = 20000
max_cumu_compaction_threads = 10 (Half of the total number of CPUs)
enable_write_index_searcher_cache = false
disable_storage_page_cache = true
enable_single_replica_load = true
streaming_load_json_max_mb=250
```
### Stream Load optimization
During peak times, the data platform is undertaking up to 1 million TPS and a writing throughput of 1GB/s. This is demanding for the system. Meanwhile, at peak time, a large number of concurrent write operations are loading data into lots of tables, but each individual write operation only involves a small amount of data. Thus, it takes a long time to accumulate a batch, which is contradictory to the data freshness requirement from the query side.
As a result, the data platform was bottlenecked by data backlogs in Apache Kafka. NetEase adopts the [Stream Load](https://doris.apache.org/docs/2.0/data-operate/import/stream-load-manual) method to ingest data from Kafka to Doris. So the key was to accelerate Stream Load. After talking to the [Apache Doris developers](https://join.slack.com/t/apachedoriscommunity/shared_invite/zt-2gmq5o30h-455W226d79zP3L96ZhXIoQ), NetEase adopted two optimizations for their log and time series data analysis:
- **Single replica data loading**: Load one data replica and pull data from it to generate more replicas. This avoids the overhead of ranking and creating indexes for multiple replicas.
- **Single tablet data loading** (`load_to_single_tablet=true`): Compared to writing data to multiple tablets, this reduces the I/O overhead and the number the small files generated during data loading.
The above measures are effective in improving data loading performance:
- **2X data consumption speed from Kafka**
- **75% lower data latency**
- **70% faster response of Stream Load**
Before putting the upgraded data platform in their production environment, NetEase has conducted extensive stress testing and grayscale testing. This is their experience in tackling errors along the way.
**1. Stream Load timeout:**
The early stage of stress testing often reported frequent timeout errors during data import. Additionally, despite the processes and cluster status being normal, the monitoring system couldn't collect the correct BE metrics. The engineers obtained the Doris BE stack using Pstack and analyzed it with PT-PMT. They discovered that the root cause was the lack of HTTP chunked encoding or content-length settings when initiating requests. This led Doris to mistakenly consider the data transfer as incomplete, causing it to remain in a waiting state. The solution was to simply add a chunked encoding setting on the client side.
**2. Data size in a single Stream Load exceeding threshold:**
The default limit is 100 MB. The solution was to increase `streaming_load_json_max_mb` to 250 MB.
**3. Error:** `alive replica num 0 < quorum replica num 1`
By the `show backends` command, it was discovered that one BE node was in OFFLINE state. A lookup in the `be_custom` configuration file revealed a `broken_storage_path`. Further inspection of the BE logs located an error message "too many open files," meaning the number of file handles opened by the BE process had exceeded the system's limit, and this caused I/O operations to fail. When Doris detected such an abnormality, it marked the disk as unavailable. Because the table was configured with one single replica, when the disk holding the only replica was unavailable, data writing failed.
The solution was to increase the maximum open file descriptor limit for the process to 1 million, delete the `be_custom.conf` file, and restart the BE node.
**4. FE memory jitter**
During grayscale testing, the FE could not be connected. The monitoring data showed that the JVM's 32 GB was exhausted, and the `bdb` directory under the FE's meta directory had ballooned to 50 GB. Memory jitter occurred every hour, with peak memory usage reaching 80%
The root cause was improper parameter configuration. During high-concurrency Stream Load operations, the FE records the related Load information. Each import adds about 200 KB of information to the memory. The cleanup time for such information is controlled by the `streaming_label_keep_max_second` parameter, which by default is 12 hours. Reducing this to 5 minutes can prevent the FE memory from being exhausted. However, they didn't modify the `label_clean_interval_second` parameter, which controls the interval of the label cleanup thread. The default value of this parameter is 1 hour, which explains the hourly memory jitter.
The solution was to dial down `label_clean_interval_second` to 5 minutes.
### Query
The engineers found results that did not match the filtering conditions in a query on the Eagle monitoring platform.
This was due to the engineers' misconception of `match_all` in Apache Doris. `match_all` identifies data records that include all the specified tokens while tokenization is based on space and punctuation marks. In the unqualified result, although the timestamp did not match, the message included "29", which compensated for the unmatched part in the timestamp. That's why this data record was included as a query result.
For Doris to produce what the engineers wanted in this query, `MATCH_PHRASE` should be used instead, because it also identifies the sequence of texts.
```sql
SELECT * FROM table_name WHERE logmsg MATCH_PHRASE 'keyword1 keyword2';
```
Note that when using `MATCH_PHRASE`, you should enable `support_phrase` during index creation. Otherwise, the system will perform a full table scan and a hard match, resulting in poor query efficiency.
```sql
INDEX idx_name4(column_name4) USING INVERTED PROPERTIES("parser" = "english", "support_phrase" = "true")
```
If you want to enable `support_phrase` for existing tables that have already been populated with data, you can execute `DROP INDEX` and then `ADD INDEX` to replace the old index with a new one. This process is incremental and does not require rewriting the entire table.
**This is another advantage of Doris compared to Elasticsearch: It supports more flexible index management and allows easy addition and removal of indexes.**
## Conclusion
Apache Doris supports the log and time series data analytic workloads of NetEase with higher query performance and less storage consumption. Beyond these, Apache Doris has other capabilities such as data lake analysis since it is designed as an all-in-one big data analytic platform.

1,915,303 | Unveiling The Crucial Benefits Of Integration Testing | Within the constantly changing world of software development, it is important to make sure that... | 0 | 2024-07-08T06:45:21 | https://www.prophecynewswatch.com/article.cfm?recent_news_id=6230 | integration, testing | 
Within the constantly changing world of software development, it is important to make sure that different parts work well together. Integration testing plays an essential role in checking if various elements like modules, APIs, and tools from other companies are working properly together within a program. While many people recognize its importance, looking more closely at the advantages shows how crucial system integration testing automation is in the cycle of development.
**Assurance of functionality**
Integration testing is essentially concerned with verifying that when applications or modules are combined, they function as anticipated. It accomplishes this by simulating situations from actual life where different parts interact with one another, confirming that the entire system operates correctly. The software creators can locate and mend issues in how parts mesh together by conducting numerous tests, which enhances the trustworthiness of the software.
**Data integrity validation**
The main goal of integration testing is to check if the data moving between modules and APIs is correct and whole. It carefully examines how data is shared, making sure that it moves through the system properly, following the set rules and shapes. Finding differences in data transfer early helps to reduce the chance of mistakes later, making a stronger and more reliable system for applications.
**Seamless integration with third-party tools**
In the digital world, where everything is connected, many apps use different third-party programs and APIs to make them work better and help things run more smoothly. Testing how these parts integrate is very important for checking if they work well with the main app without any problems. It ensures that integrations are accurate to prevent any potential problems with compatibility, which in turn guarantees a smooth experience for the user.
**Identification of structural anomalies**
Integration testing goes further than just checking if things work; it acts as a careful protector, watching for problems in the way the application is built. It can find hidden problems like issues with database structures or mistakes with how caches are set up that might not show up until the application is being used for real. When teams find and fix these unusual things early when making the software, integration testing makes the basic structure stronger so that future problems can be avoided.
**Risk mitigation against total software failure**
The impact of software not working can be severe, leading to financial loss and damage to the company's reputation. Testing the integration acts as a safeguard, preventing major issues with the system by making these events less probable. Checking combined parts helps in identifying and solving weak points, boosting the overall capability of the software system for tolerating problems.
**Validation of structural changes**
As software develops, it often needs changes in its architecture which means teams must be careful to keep smooth interactions between parts. Testing how well different sections work together helps check these architectural changes, allowing programmers to understand the effect on how the system acts and its efficiency. Integration testing gives important understanding when a user goes from one part to another or there is a change in the base architecture, helping teams to choose wisely.
**Conclusion**
To sum up, combining different parts of software to test them together is very important and a key part of making software. This kind of testing does many good things like checking that all functions work together well and lowering the chance of big problems happening. It plays an essential role in creating strong and dependable programs.

1,915,308 | การจัดการ Enum ใน PostgreSQL: เพื่อประสิทธิภาพและความชัดเจนให้ฐานข้อมูลของคุณ | Enum คือ Enum หรือ Enumerated Type ใน PostgreSQL เป็นเสมือนเซ็ตค่าที่กำหนดไว้ล่วงหน้า... | 0 | 2024-07-08T06:48:16 | https://dev.to/everthing-was-postgres/kaarcchadkaar-enum-ain-postgres-49e3 | ## Enum คือ ##
Enum หรือ Enumerated Type ใน PostgreSQL เป็นเสมือนเซ็ตค่าที่กำหนดไว้ล่วงหน้า ช่วยให้คุณจำกัดข้อมูลในคอลัมน์ให้อยู่ในกรอบที่ต้องการ นึกภาพว่าคุณมีตู้เสื้อผ้าที่มีช่องเฉพาะสำหรับเสื้อผ้าแต่ละประเภท - นั่นแหละคือแนวคิดของ Enum!
ตัวอย่างที่พบบ่อย:
- วันในสัปดาห์: จันทร์, อังคาร, พุธ, ...
- สถานะการส่งสินค้า: กำลังแพ็คของ, กำลังจัดส่ง, จัดส่งสำเร็จ
- ระดับความสำคัญของงาน: ต่ำ, ปานกลาง, สูง
## การจัดการ Enum ##
###1.การสร้างประเภทข้อมูล Enum ##
```sql
CREATE TYPE mood AS ENUM ('happy', 'neutral', 'sad');
```
คำสั่งนี้สร้าง Enum ชื่อ 'mood' ที่มีค่าเป็นไปได้ 3 ค่า
โดยสามารถตรวจสอบ type ที่สรา้งขึ้นผ่านคำสั่ง
```sql
SELECT n.nspname as enum_schema,
t.typname as enum_name,
e.enumlabel as enum_value
FROM pg_type t
JOIN pg_enum e ON t.oid = e.enumtypid
JOIN pg_catalog.pg_namespace n ON n.oid = t.typnamespace;
```
จะแสดงรายการ
###2.การนำ Enum ไปใช้ในตารางข้อมูล###
เราสามารถใช้งานมันในตารางได้เหมือนกับประเภทข้อมูลอื่นๆ เพียงระบุชื่อ Enum ในนิยามคอลัมน์
```sql
CREATE TABLE daily_log (
id SERIAL PRIMARY KEY,
date DATE NOT NULL,
user_mood mood NOT NULL DEFAULT 'happy'
);
```
เป็นการสรา้งตาราง daily_log โดยคอลัมน์ user_mood ซึ่งเป็นประเภทข้อมูล mood Enum ที่สร้างไว้ก่อนหน้า
###3.การเพิ่มข้อมูลโดยใช้ Enum ###
```sql
INSERT INTO daily_log (date, user_mood) VALUES
('2024-07-12', 'happy'),
('2024-07-13', 'neutral'),
('2024-07-14', 'sad');
```
###4.การค้นหาข้อมูลโดยใช้ Enum###
```sql
-- หาบันทึกทั้งหมดที่ผู้ใช้มีความรู้สึกมีความสุข
SELECT * FROM daily_log WHERE user_mood = 'happy';
-- หาบันทึกที่ผู้ใช้ไม่มีความสุข
SELECT * FROM daily_log WHERE user_mood != 'happy';
```
###5.การอัปเดตข้อมูลใน Enum ###
การอัปเดตข้อมูลในคอลัมน์ Enum เช่นเดียวกับคอลัมน์ประเภทข้อมูลอื่นๆ
```sql
UPDATE daily_log
SET mood = 'happy'
WHERE id = 3;
```
ตัวอย่างข้างต้นเปลี่ยนแปลง user_mood ในตาราง dialy_log ที่มีค่า id 3 เป็น happy
###6.การลบ Enum###
การลบ Enum ได้ด้วยคำสั่ง DROP TYPE
```sql
DROP TYPE mood;
```
อย่างไรก็ตาม โปรดทราบว่าการลบ Enum จะลบการอ้างอิงทั้งหมดในตารางออกด้วย
##เทคนิคการใช้ Enum##
###การตรวจสอบ###
```sql
-- ตรวจสอบว่าค่าอยู่ใน Enum หรือไม่
SELECT 'happy'::mood; -- ทำงานได้
SELECT 'excited'::mood; -- เกิด error
-- ดึงรายการค่าทั้งหมดของ Enum
SELECT enum_range(NULL::mood);
```
###การเปรียบเทียบและเรียงลำดับใน Eum###
การเรียงลำดับค่า Enum ตามที่ประกาศไว้ เช่นเมื่อเราประกาศ type enum
```sql
--จากenum mood ที่สร้างขึ้นค่า 'happy' จะถูกเรียงลำดับก่อน 'neutral'
--และ 'neutral'จะถูกเรียงลำดับก่อน'sad'
-- หาบันทึกที่มีความรู้สึกดีกว่า 'neutral'
SELECT * FROM daily_log WHERE user_mood > 'neutral';
-- หาบันทึกที่มีความรู้สึกที่ไม่ใช่ 'sad'
SELECT * FROM daily_log WHERE user_mood <> 'sad';
--เรียงบันทึกความรู้สึกจาก happy ไปถึง sad
SELECT * FROM daily_log ORDER BY user_mood;
```
###ฟังก์ชัน Enum ในตัว###
ใน Postgres มีฟังก์ชันตัวในการจัดการกับ Enum ฟังก์ชันเหล่านี้ช่วยให้คุณสามารถตรวจสอบว่าค่าอยู่ใน Enum หรือไม่ แปลงค่าเป็นตัวอักษร หรือดึงรายการค่าที่เป็นไปได้ทั้งหมด
**- has_any_status(status_array, status)**: ตรวจสอบว่าค่าใดๆ ใน status_array อยู่ใน status หรือไม่
**-has_status(status, value)**: ตรวจสอบว่า value อยู่ใน status หรือไม่
**- enum_label(status, value)**: แปลง value เป็นตัวอักษร
**- enum_range(status)**: ดึงรายการค่าที่เป็นไปได้ทั้งหมดของ status
##บทสรุป: Enum - เครื่องมือทรงพลังสำหรับฐานข้อมูลของคุณ##
Enum ใน PostgreSQL เป็นเหมือนกล่องเครื่องมือพิเศษที่ช่วยให้คุณจัดการข้อมูลได้อย่างมีประสิทธิภาพ ปลอดภัย และชัดเจน แม้จะมีข้อจำกัดบ้าง แต่ด้วยการใช้งานอย่างชาญฉลาด Enum สามารถยกระดับการทำงานกับฐานข้อมูลของคุณได้อย่างมาก
ลองนำ Enum ไปใช้ในโปรเจกต์ถัดไปของคุณ และสัมผัสถึงความแตกต่างด้วยตัวคุณเอง!สำหรับคอลัมน์ที่มีค่าจำนวนมาก
โดยรวมแล้ว Enum เป็นเครื่องมือที่มีประสิทธิภาพสำหรับการจัดเก็บข้อมูลประเภทหมวดหมู่ใน Postgres ช่วยให้มั่นใจได้ว่าข้อมูลถูกต้อง ชัดเจน และง่ายต่อการจัดการ

title: SQLC & dynamic queries
published: true

---
[SQLC](https://github.com/sqlc-dev/sqlc) has become my go-to tool for interacting with databases in Go. It gives you full control over your queries since you end up writing SQL yourself. It then generates models and type safe code to interact with those queries.
I won’t go over the basics here, if you feel like it you can try their [interactive playground](https://play.sqlc.dev/).
## Dynamic queries
Frequently I end up needing to filter the data by a set of fields in the database. This set of fields is often determined by the caller, be it via REST API or other means. This means that the code I’m writing has to support dynamic queries, where we query by a subset of fields.
Let’s see an example. Assume my API returns some car data and I store it in the following table:
```sql
CREATE TABLE cars(
id SERIAL PRIMARY KEY,
brand VARCHAR(255) NOT NULL,
model VARCHAR(255) NOT NULL,
year INT NOT NULL,
state VARCHAR(255) NOT NULL,
color VARCHAR(255) NOT NULL,
fuel_type VARCHAR(50) NOT NULL,
body_type VARCHAR(50) NOT NULL
);
```
The user might want to filter by brand, or by model. Or by brand and model. Or by brand, color, model, state and body type. You get the point, there’s a whole bunch of permutations here and SQLC is not great at handling this.
I usually approach it with the following SQLC query:
```sql
SELECT * FROM cars
WHERE brand = @brand -- mandatory fields go in like this
AND (NOT @has_model::boolean or model = @model) -- optional fields follow this pattern
AND (NOT @has_year::boolean or year = @year)
AND (NOT @has_state::boolean or state = @state)
AND (NOT @has_color::boolean or color = @color)
AND (NOT @has_fuel_type::boolean or fuel_type = @fuel_type)
AND (NOT @has_body_type::boolean or body_type = @body_type);
```
It might not be the prettiest solution, but it has worked for me quite well. There are a couple of downsides though. First, the param struct that the SQLC generates contains quite a bunch of fields:
```go
type GetCarsParams struct {
Brand string
HasModel bool
Model string
HasYear bool
Year int32
HasState bool
State string
HasColor bool
Color string
HasFuelType bool
FuelType string
HasBodyType bool
BodyType string
}
```
You’ll have to handle this in your code, to set the proper ones if the user provides the relevant input. Second, people always ask me if there is a cost associated with having such a query versus using something like a query builder to build the query with specific params. To this, I always answer: “Probably, but it’s unlikely you’ll notice”.
I have decided to try and benchmark this, to see if there is a meaningful cost associated with it.
## Benchmarking setup
I’ll use postgres & pgbench, since I’m only really interested in the query performance ignoring any code overhead. For schema, we’ll use the table above.
We’ll seed the data with the following query:
```sql
INSERT INTO cars(brand, model, YEAR, state, color, fuel_type, body_type)
SELECT (CASE FLOOR(RANDOM() * 5)::INT
WHEN 0 THEN 'Toyota'
WHEN 1 THEN 'Ford'
WHEN 2 THEN 'Honda'
WHEN 3 THEN 'BMW'
WHEN 4 THEN 'Tesla'
END) AS brand,
(CASE FLOOR(RANDOM() * 5)::INT
WHEN 0 THEN 'Camry'
WHEN 1 THEN 'F-150'
WHEN 2 THEN 'Civic'
WHEN 3 THEN '3 Series'
WHEN 4 THEN 'Model S'
END) AS model,
(CASE FLOOR(RANDOM() * 5)::INT
WHEN 0 THEN 2024
WHEN 1 THEN 2023
WHEN 2 THEN 2022
WHEN 3 THEN 2021
WHEN 4 THEN 2020
END) AS YEAR,
(CASE FLOOR(RANDOM() * 3)::INT
WHEN 0 THEN 'Operational'
WHEN 1 THEN 'Under maintenance'
WHEN 2 THEN 'Totalled'
END) AS state,
(CASE FLOOR(RANDOM() * 5)::INT
WHEN 0 THEN 'Red'
WHEN 1 THEN 'Green'
WHEN 2 THEN 'Blue'
WHEN 3 THEN 'Black'
WHEN 4 THEN 'White'
END) AS color,
(CASE FLOOR(RANDOM() * 3)::INT
WHEN 0 THEN 'Diesel'
WHEN 1 THEN 'Petrol'
WHEN 2 THEN 'Electric'
END) AS fuel_type,
(CASE FLOOR(RANDOM() * 3)::INT
WHEN 0 THEN 'Sedan'
WHEN 1 THEN 'SUV'
WHEN 2 THEN 'Hatchback'
END) AS body_type
FROM GENERATE_SERIES(1, 10000000) seq;
```
We’ll then have two different queries - one that we’d build with a query builder:
```sql
SELECT * FROM cars
WHERE brand = 'Ford'
and model = 'Model S'
and year = 2021
and color = 'Green'
and fuel_type = 'Diesel';
```
And one where we’d have some extra overhead from our SQLC approach:
```sql
SELECT * FROM cars
WHERE brand = 'Ford'
AND (NOT true::boolean or model = 'Model S')
AND (NOT true::boolean or year = 2021)
AND (NOT false::boolean or state = '')
AND (NOT true::boolean or color = 'Green')
AND (NOT true::boolean or fuel_type = 'Diesel')
AND (NOT false::boolean or body_type = '');
```
I’ve also added a composite index for these specific queries:
```sql
CREATE INDEX idx_cars_brand_model_year_color_fuel
ON cars (brand, model, year, color, fuel_type);
```
Armed with this, I’ve spun up an instance of postgres in docker on my machine, created the schema and generated the dataset. I then pre-warmed the cache by executing a couple of pgbench runs but not logging any results.
From there, I ran pgbench 4 times:
```
pgbench -f builderq.sql --log --log-prefix=builder --transactions=10000 -j 5 -c 5
pgbench -f sqlcq.sql --log --log-prefix=sqlc --transactions=10000 -j 5 -c 5
pgbench -f builderq.sql --log --log-prefix=builder --transactions=1000 -j 5 -c 5
pgbench -f sqlcq.sql --log --log-prefix=sqlc --transactions=10000 -j 5 -c 5
```
And these are the latencies for both queries after being run through plotly:
[](https://dizzy.zone/2024/07/03/SQLC-dynamic-queries/nolimit.png)
There is very little difference between the two, with SQLC approach having a larger number of outliers. Despite this, I would state that there is no significant difference between the two.
I then re-ran the experiment, only this time introduced a limit of 1 on both queries. My thought process was that this would perhaps allow the faster(in theory) query to shine, since we would not have to spend so much time transferring data. Here is the box plot:
[](https://dizzy.zone/2024/07/03/SQLC-dynamic-queries/limit.png)
The SQLC approach does seem a tad slower here, but not by a lot.
In conclusion, there is very little difference in terms of performance for these queries, meaning that using the a bunch of `AND`s to implement dynamic querying in SQLC is something you can do without fear of massive performance repercussions. Your mileage may vary and in extreme cases this might not be these - always benchmark your own use cases.
The only price you pay for manually constructing the dynamic queries is the manual work involved in writing the queries & mapping of values from the request parameters to the query parameters.

1,915,318 | How Do Video and Voice Calls Work? | Important for Interview In many interviews, candidates are often asked to explain how... | 0 | 2024-07-08T06:50:12 | https://dev.to/saanchitapaul/how-do-video-and-voice-calls-work-3n47 | webdev, deeplearning, learning, interview | ## Important for Interview
**In many interviews, candidates are often asked to explain how video or voice calls work. This article provides a high-level overview of the functioning of voice and video calls.**
**Voice over Internet Protocol (VoIP)** is one of the most popular standards for voice and video calling over the web.
We all use voice and video on various platforms like WhatsApp, Skype, Messenger, Facebook, etc. Both voice and video calls depend on how we stream media between the two clients which are connected to each other. So, there must be something that can do the work of media streaming from one client to another client.
For media streaming, we need to know about **WebRTC**.
**WebRTC** is a free, open project that provides browsers and mobile applications with **Real-Time Communications (RTC) **capabilities via simple APIs. The WebRTC components have been optimized to serve this purpose best.
But there are many other things that we need to do as WebRTC is not enough for complete implementation.
**Other Items to Consider Are:**
**- Signaling**
**- STUN Server**
**- TURN Server**
## Signaling
**What is Signaling?**
To set up a call between two clients, both clients must conform to each other by sending key data, messages, and metadata about the media. Over signaling, we do these things.
We can use WebSocket for signaling.
Signaling is just used to know that these two clients want to connect for the call.
> Signaling may be accomplished via WebSocket.
## Peer-to-Peer Connection
After signaling, we need to connect both the client peer to peer. For connecting, we must have the public IP address of both clients.
So, to get the public IP address, we use the STUN Server.
## STUN Server
STUN Server is used to get the public IP address.
**Why do we need a public IP address?
**
A Public IP Address is an IP address that is globally unique across the Internet. Only one device may have a public IP address.
A Private IP Address is an IP address that is not globally unique and may exist simultaneously on many different devices. A private IP address is never directly connected to the Internet.
**The NAT(Network Address Translation)** provides the local IP address of the device which can't be used publicly to connect peer to peer. And for WebRTC, we need to have a public IP address. STUN Server provides that.
If everything is fine, we get the public IP addresses of both clients, and then, we connect both clients through WebRTC to start the call. WebRTC handles all the media streaming.
> The real-world connectivity is not ideal.
In case, we are not able to get the public IP address of both clients. Then we can't connect peer to peer. In that case, we need the TURN Server.
## TURN Server
TURN Server is used to connect both clients if peer-to-peer fails by acting as a mediator. It takes the data from one client and sends it to another client. So, its job is to relay the media.
This way, the two clients start talking to each other.
The other small data that are not related to media like a client cuts the call, any setting changes, messages, etc are sent over the signaling process.
> The following question arises:
**Why WebRTC can't do signaling?**
Answer: In order to reduce redundancy and promote compatibility with existing technologies, the WebRTC Standards do not specify signaling techniques or protocols. WebRTC is designed with media in mind. As a result, the voice and video calls function properly.
WebRTC is optimized for media.
## Conclusion
Voice over Internet Protocol (VoIP) is a technology that enables you to make voice calls via a broadband Internet connection rather than a traditional (or analog) phone line. Some VoIP services may only enable you to contact other VoIP users, whilst others may allow you to call anybody with a phone number, including local, long-distance, mobile, and international lines. Furthermore, while some VoIP services require you to utilize a computer or a specific VoIP phone, others enable you to use a regular phone linked to a VoIP adaptor.

LLMs have unlocked countless opportunities to tackle once unsolvable problems, thanks to their exceptional reasoning and decision-making capabilities. Among their many strengths, one of the most significant is their general code understanding, which can be leveraged to build tools that write, re-write, and review code.
Building on this capability, in this article, you will create an AI Agent that reviews GitHub pull requests, posts them as a comment in GitHub, and sends a summary of it to a configured Slack channel. For this, you will use LangChain Agents and Composio tools.
## Key Objectives
- Understand what Composio is.
- Learn about LangChain and building agents with it.
- Understand the workflow of the PR agent.
- Learn how to build the agent with LangChain and Composio.
## What is Composio?
[Composio](https://www.composio.dev/) is an open-source platform that provides tools and integrations for building AI agents. Many applications like Slack, GitHub, Linear, etc., require complex user authentication and authorization mechanisms, and adding these integrations to your agentic workflow can be quite challenging. Composio addresses this by offering built-in user authentication and authorization management to streamline your AI application development workflow. It also lets you add applications with only a few lines of code. Composio offers an easy way to integrate your application with AI agents.
Composio supports authentication mechanisms such as OAuth, JWT, ApiKey, and basic authentication. It handles the authentication and authorization of your users, enabling the agents to integrate tools to perform actions on behalf of your users.
For this walkthrough, you need to understand two key Composio concepts:
- **Actions**: In Composio, actions are tasks performed on behalf of the users. For instance, if you have configured a GitHub integration, you can perform actions like starting a repository, updating the README file, etc. Composio wraps all the GitHub API features and optimizes them for LLM tool calls.
- **Triggers**: Triggers are predefined conditions that, when met, initiate actions from your agents. Composio offers a built-in webhook to capture trigger events. The webhooks receive a payload from integrations in real time, letting you perform actions on event data. For example, if a `slack_receive_message` trigger is configured for your Slack integration, the Slack app will send the event data like text, time, and channel ID to the webhook at the backend.
## What is LangChain?
LangChain is an open-source framework for AI-powered applications. It offers LLM chains, vector stores, graph stores, databases, document loaders, parsers, and many more components to build a complete backend for AI applications. Because of its versatility and popularity, it has become the default choice for building AI-powered systems.
In this article, you will use LangChain Agents and other components with Composio tools to build the PR agent.
## Workflow Overview
The workflow involves a Slack bot, your GitHub app integration, a webhook at the backend, and a LangChain Agent.
With Composio, you can integrate a Slack bot and connect to GitHub. The Slack integration allows you to send and receive messages within Slack channels, while the GitHub integration enables you to fetch pull request diffs.
When someone makes a pull request to the configured repository, the trigger activates and sends the event data to the backend webhook. The event payload is then forwarded to the LangChain agent. Following the provided instructions, the agent reviews the code, summarizes it, posts the review as a comment on the pull request, and also sends the summary to the configured Slack channel.
## Prerequisites
To complete this tutorial, you will need a Composio account and access to the GPT-4 API. You can create a free Composio account [here](https://composio.com/signup). Consider using Mixtral 8x7B from Groq as an alternative OpenAI GPT-4.
Get the API keys for both Composio and the LLM provider. For Composio, click on the Settings tab to view your API key.
## Building the PR Agent
Now that you have grasped the basics of Composio and understood the workflow, let's build the agent. But before that, let’s set up the development environment.
### Step 1: Setting up Development Environment
Create a virtual environment using Python Venv:
```
python -m venv myenv
source myenv/bin/activate # On Windows use `myenv\Scripts\activate`
```
Install the following libraries.
```
pip install composio-core composio-langchain /
langchain-openai/
python-dotenv
```
## Step 2: Setting Environment Variables
Create a `*.env*` file and add the following environment variables:
```
COMPOSIO_API_KEY=your Composio API key
OPENAI_API_KEY=your OpenAI API key
SLACK_CHANNEL_ID=slack channel ID, you want the summary posted
```
To authenticate your Composio account, run the following command and follow the login flow:
```
composio login
```
## Step 3: Defining Tools and LLM
Now, import the libraries and define the required tools and LLM.
```
import os
from dotenv import load_dotenv
from composio_langchain import Action, ComposioToolSet
from langchain import hub
from langchain.agents import AgentExecutor, create_openai_functions_agent
from langchain_openai import ChatOpenAI
from composio.client.collections import TriggerEventData
load_dotenv()
# Initialize the ComposioToolSet
composio_toolset = ComposioToolSet()
# Define the tools
pr_agent_tools = composio_toolset.get_actions(
actions=[
Action.GITHUB_GET_CODE_CHANGES_IN_PR,
Action.GITHUB_PULLS_CREATE_REVIEW_COMMENT,
Action.GITHUB_ISSUES_CREATE,
Action.SLACKBOT_CHAT_POST_MESSAGE,
]
)
# Initialize the language model
llm = ChatOpenAI(model="gpt-4")
```
We are using four different actions from Composio. Each action performs a single specific task:
- **Action.GITHUB_GET_CODE_CHANGES_IN_PR**: Retrieves the code changes in a GitHub pull request.
- **Action.GITHUB_PULLS_CREATE_REVIEW_COMMENT**: Creates a review comment on a GitHub pull request.
- **Action.GITHUB_ISSUES_CREATE**: Creates a new issue in a GitHub repository.
- **Action.SLACKBOT_CHAT_POST_MESSAGE**: Sends a message to a Slack channel using a Slack bot.
## Step 4: Defining the LangChain Agent
Next, define the OpenAI functions agent from LangChain with a system prompt to provide context about the workflow, LLM, and tools.
```
code_review_assistant_prompt = """
You are an experienced code reviewer.
Your task is to review the provided file diff and give constructive feedback.
Follow these steps:
1. Identify if the file contains significant logic changes.
2. Summarize the changes in the diff in clear and concise English, within 100 words.
3. Provide actionable suggestions if there are any issues in the code.
Once you have decided on the changes, for any TODOs, create a GitHub issue.
And send the summary of the PR review to """+os.environ['CHANNEL_ID']+""" channel on Slack. Slack doesn't have markdown so send a plain text message.
Also, add the comprehensive review to the PR as a comment.
"""
prompt = hub.pull("hwchase17/openai-functions-agent")
combined_prompt = prompt+code_review_assistant_prompt
query_agent = create_openai_functions_agent(llm, pr_agent_tools, combined_prompt)
agent_executor = AgentExecutor(agent=query_agent, tools=pr_agent_tools, verbose=True)
print("Assistant is ready")
```
## Step 5: Defining the Event Listener
Finally, define the event listener. This will be used to capture event payloads from the GitHub trigger. Composio's built-in event listener webhook can be configured to pick event data only from relevant trigger events.
```
# Create a trigger listener
listener = composio_toolset.create_trigger_listener()
@listener.callback(filters={"trigger_name": "github_pull_request_event"})
def review_new_pr(event: TriggerEventData) -> None:
# Using the information from Trigger, execute the agent
code_to_review = str(event.payload)
query_task = f"Review the following code changes: {code_to_review}"
# Execute the agent
res = agent_executor.invoke({"input": query_task})
print(res)
print("Listener started!")
print("Create a pr to get the review")
listener.listen()
```
In the code above, the callback function review_new_pr is invoked, when a PR is raised in the repository. The function receives the event data which is then passed to agent_executor. The agent executes the task as explained earlier.
Putting everything together.
```
import os
from dotenv import load_dotenv
from composio_langchain import Action, ComposioToolSet
from langchain import hub
from langchain.agents import AgentExecutor, create_openai_functions_agent
from langchain_openai import ChatOpenAI
from composio.client.collections import TriggerEventData
load_dotenv()
# Initialize the ComposioToolSet
composio_toolset = ComposioToolSet()
# Define the code review assistant prompt
code_review_assistant_prompt = """

Action.GITHUB_PULLS_CREATE_REVIEW_COMMENT,
Action.GITHUB_ISSUES_CREATE,
Action.SLACKBOT_CHAT_POST_MESSAGE,
]
)
# Initialize the language model
llm = ChatOpenAI(model="gpt-4")
prompt = hub.pull("hwchase17/openai-functions-agent")
combined_prompt = prompt+code_review_assistant_prompt
query_agent = create_openai_functions_agent(llm, pr_agent_tools, combined_prompt)
agent_executor = AgentExecutor(agent=query_agent, tools=pr_agent_tools, verbose=True)
print("Assistant is ready")
# Create a trigger listener
listener = composio_toolset.create_trigger_listener()
@listener.callback(filters={"trigger_name": "github_pull_request_event"})
def review_new_pr(event: TriggerEventData) -> None:

code_to_review = str(event.payload)
query_task = f"Review the following code changes: {code_to_review}"
# Execute the agent
res = agent_executor.invoke({"input": query_task})
print(res)
print("Listener started!")
print("Create a pr to get the review")
listener.listen()
```
Now, once everything is set up, run the Python file. Make sure you have set up the Slack bot correctly in your channel.

- **Complex state management:** Applications requiring persistent connections or complex state management, such as multiplayer online games or real-time chat applications, may face challenges with Lambda. Maintaining a state across stateless function invocations can take time and effort. Cloud architects should consider traditional server setups for such use cases.
## Security implications of AWS Lambda
- **Least privilege principle:** Lambda functions should follow the principle of least privilege, ensuring they have only the necessary permissions to perform their tasks. This minimizes the risk of unauthorized access and potential security breaches. Cloud architects must ensure strict access controls and permission settings.
- **Environment variables:** Avoid storing sensitive data like API keys or credentials in environment variables. Instead, utilize AWS Secrets Manager or AWS Systems Manager Parameter Store for secure storage and retrieval of sensitive information. Developers should follow best practices for handling confidential information.
- **VPC integration:** Running Lambda functions within a Virtual Private Cloud (VPC) can enhance security by restricting network access to AWS resources. This isolates Lambda functions from the public internet, reducing exposure to potential attacks. Security-conscious architects can leverage VPC integration for additional protection.
- **IAM roles:** Properly configured IAM roles and policies are crucial for Lambda functions. Assigning specific roles to functions ensures they can access only the resources they need, reducing the risk of privilege escalation.

The global [palm oil market](https://www.persistencemarketresearch.com/market-research/palm-oil-market.asp) has experienced significant growth over the past decade, driven by rising demand from various regions and sectors. This versatile commodity is extensively used in food production, cosmetics, and biofuels, making it a crucial component of global trade. As the market continues to expand, understanding the regional dynamics and market insights is essential. This press release explores the booming regional demand and provides comprehensive market insights into the global palm oil market.
**Market Overview**
The global palm oil market is expected to grow significantly, with consumption reaching a valuation of US$ 59.75 billion in 2022 and projected to top US$ 90.1 billion by 2032, expanding at a CAGR of 4.2%. Palm oil accounts for 25% to 30% of the global edible oil market, with South Asia leading with a 39.7% market share. From 2017 to 2021, the market witnessed a CAGR of 3.3%. The increasing health consciousness among consumers is driving demand for pure, naturally extracted edible oils like palm oil, which are free of GMOs, gluten, dairy, additives, preservatives, and chemicals. Transparency and traceability in food production processes are also boosting consumer interest in high-quality palm oil products.
**Regional Demand Analysis**
Asia-Pacific
The Asia-Pacific region continues to dominate the palm oil market, both in production and consumption. Countries like Indonesia and Malaysia are the largest producers, benefiting from favorable climatic conditions and extensive plantation areas.

Europe
Europe is a significant market for palm oil, with demand driven by the food industry and biofuel production. The European Union has stringent regulations promoting the use of renewable energy sources, which has increased the demand for palm oil-based biodiesel. However, sustainability concerns have led to a preference for certified sustainable palm oil (CSPO), and the region is a major importer of RSPO-certified palm oil.
Africa
Africa is an emerging market for palm oil, with increasing demand from both the food industry and local consumers. Countries such as Nigeria and Ghana are key producers, while South Africa is a significant consumer. The growing urban population and rising disposable incomes are fueling the demand for palm oil-based products. Additionally, there is potential for expanding palm oil cultivation in the region, which could boost production.
Latin America
Latin America is another region witnessing a surge in palm oil demand. Brazil and Colombia are the major producers, with expanding plantation areas.

Manufacturers are investing in research and development to reduce the saturated fat content of palm oil and enhance its nutritional profile. These efforts aim to address consumer health concerns and offer healthier alternatives.
Price Volatility
The palm oil market is subject to price fluctuations due to factors such as weather conditions, geopolitical tensions, and changes in import-export policies. Managing price volatility is crucial for both producers and consumers. Diversifying supply sources and improving yield productivity are strategies being employed to mitigate the impact of price swings.
Regulatory Environment
Government regulations and policies play a significant role in shaping the palm oil market. Renewable energy mandates, import-export tariffs, and sustainability requirements influence market dynamics. Industry stakeholders are actively engaging with policymakers to promote favorable regulations that support sustainable growth.
**Future Prospects**
The future of the global palm oil market looks promising, with several key trends and opportunities on the horizon:
Expansion of Certified Sustainable Palm Oil
The demand for certified sustainable palm oil (CSPO) is expected to grow, driven by consumer awareness and regulatory requirements. Producers will continue to adopt sustainable practices and seek certification to meet this demand.
Growth in Emerging Markets
Emerging markets in Africa and Latin America offer significant growth potential. Expanding palm oil cultivation and increasing consumption in these regions will contribute to global market growth.
Innovation in Products

The market for fatty acid supplements is projected to grow at a compound annual growth rate (CAGR) of 7%, increasing its revenue from US$ 5,406.0 million in 2023 to approximately US$ 10,834.9 million by 2033. This growth reflects rising consumer awareness and increased consumption driven by education through various channels.
The _[Fatty acids supplements market ](https://www.persistencemarketresearch.com/market-research/fatty-acids-supplements-market.asp)_essential for human nutrition, play crucial roles in cardiovascular and cognitive function development. Recent studies have explored potential links between omega-3 fatty acids and conditions like polycystic ovary syndrome (PCOS), though conclusive findings remain elusive.
As research advances, insights into the impact of fatty acids on human health are expected to expand, driving demand for fatty acid supplements across diverse health applications.
Omega-3 fatty acids are essential nutrients known for their wide-ranging health benefits, prompting their popularity in the form of dietary supplements. This article explores the diverse advantages of omega-3 fatty acid supplements, supported by scientific research and consumer insights.
Cardiovascular Health:
Omega-3 fatty acids, particularly EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), play a crucial role in maintaining heart health:
Reduced Risk of Heart Disease: Studies indicate that omega-3s help lower triglycerides, reduce blood pressure, and prevent plaque buildup in arteries, thereby lowering the risk of cardiovascular events.
Improved Cholesterol Levels: EPA and DHA promote healthy cholesterol levels by increasing HDL (good cholesterol) and reducing LDL (bad cholesterol) levels.
Brain Function and Cognitive Health:
Enhanced Brain Development: DHA is a major structural component of the brain and plays a vital role in cognitive function, memory, and learning ability, especially in infants and young children.
Support for Mental Health: Omega-3s may alleviate symptoms of depression, anxiety, and other mood disorders by reducing inflammation in the brain and supporting neurotransmitter function.
Joint and Bone Health:
Anti-inflammatory Properties: Omega-3 fatty acids have natural anti-inflammatory effects that help reduce joint pain and stiffness associated with conditions like arthritis.
Bone Density Support: DHA may contribute to improved bone density and reduced risk of osteoporosis, particularly in postmenopausal women.
Eye Health:
Protection Against Age-Related Macular Degeneration (AMD): Consuming omega-3 fatty acids may lower the risk of AMD, a leading cause of vision loss in older adults, by supporting retinal health and reducing inflammation.
Inflammatory Conditions:
Management of Inflammatory Diseases: Omega-3s have been shown to alleviate symptoms of chronic inflammatory conditions such as rheumatoid arthritis, inflammatory bowel disease (IBD), and psoriasis.
Pregnancy and Infant Development:
Fetal Development: Adequate intake of DHA during pregnancy supports fetal brain and eye development, potentially reducing the risk of preterm birth and promoting healthy birth outcomes.
Breastfeeding Benefits: Nursing mothers who consume omega-3 fatty acids may pass on these nutrients to their infants through breast milk, supporting early cognitive development.
Skin Health:
Moisture Retention: Omega-3 fatty acids help maintain skin hydration and elasticity, contributing to a healthy complexion and potentially reducing symptoms of skin disorders like eczema and acne.
Overall Well-being:
General Health Maintenance: Regular supplementation with omega-3 fatty acids supports overall health and well-being by reducing systemic inflammation, supporting immune function, and promoting cellular health.
Conclusion:
Omega-3 fatty acid supplements offer a plethora of health benefits that support various aspects of physical and mental well-being. From cardiovascular protection to cognitive enhancement and joint health, the evidence supporting their efficacy continues to grow. Incorporating omega-3s into one's diet or through supplements can contribute significantly to maintaining optimal health throughout life stages.

The... | 0 | 2024-07-08T07:03:01 | https://dev.to/hirelaraveldevelopers/laravel-developers-in-house-vs-freelance-whats-best-for-your-project-5epa | webdev, beginners, javascript, ai | <h4><strong>Introduction</strong></h4>
<p>When embarking on a new project, choosing the right development team is crucial. The decision often boils down to hiring in-house developers or opting for freelancers. This article dives into the pros and cons of both options, specifically focusing on Laravel developers, to help you determine what’s best for your project.</p>
<h4><strong>Understanding Laravel Development</strong></h4>
<h5><strong>What is Laravel?</strong></h5>
<p>Laravel is a powerful PHP framework designed for web application development. It offers a clean and elegant syntax, making it a favorite among developers. Its robust features and tools streamline the development process, resulting in efficient and scalable applications.</p>
<h5><strong>Benefits of Using Laravel</strong></h5>
<p>Laravel boasts numerous benefits including robust security features, efficient database management, a vast ecosystem of tools, and an active community. Its MVC architecture ensures a structured and clean codebase, making maintenance and scaling easier.</p>
<h4><strong>The Role of a Laravel Developer</strong></h4>
<h5><strong>Key Responsibilities</strong></h5>
<p>A Laravel developer is responsible for building and maintaining web applications using the Laravel framework. This includes designing database structures, developing backend logic, implementing user interfaces, and ensuring application security.</p>
<h5><strong>Required Skills</strong></h5>
<p>Essential skills for a Laravel developer include proficiency in PHP, understanding MVC architecture, experience with databases like MySQL, and familiarity with front-end technologies such as HTML, CSS, and JavaScript. Problem-solving skills and attention to detail are also crucial.</p>
<h4><strong>In-House Laravel Developers</strong></h4>
<h5><strong>Pros of Hiring In-House</strong></h5>
<p>Hiring in-house Laravel developers offers several advantages:</p>
<h6><strong>Consistent Team Collaboration</strong></h6>
<p>In-house developers work closely with your team, fostering strong collaboration and seamless communication. This results in a unified vision and better alignment with company goals.</p>
<h6><strong>Deep Understanding of Company Culture</strong></h6>
<p>In-house developers are immersed in your company culture, understanding your business values and objectives, which translates into more cohesive and tailored development work.</p>
<h6><strong>Immediate Availability</strong></h6>
<p>Having developers on-site means they are readily available to address issues, make quick decisions, and adapt to changes promptly.</p>
<h5><strong>Cons of Hiring In-House</strong></h5>
<p>However, there are some drawbacks:</p>
<h6><strong>Higher Costs</strong></h6>
<p>Employing in-house developers involves significant costs including salaries, benefits, office space, and equipment. This can be a financial burden for startups or small businesses.</p>
<h6><strong>Limited Talent Pool</strong></h6>
<p>Depending on your location, finding skilled Laravel developers locally might be challenging, limiting your options and potentially impacting the quality of your hires.</p>
<h4><strong>Freelance Laravel Developers</strong></h4>
<h5><strong>Pros of Hiring Freelancers</strong></h5>
<p>Freelancers offer a different set of benefits:</p>
<h6><strong>Cost-Effective</strong></h6>
<p>Freelancers typically cost less than in-house developers as you only pay for the work done, without the added expenses of benefits or office space.</p>
<h6><strong>Flexibility</strong></h6>
<p>Freelancers can be hired on a project-by-project basis, allowing you to scale your team up or down based on current needs, which is ideal for businesses with fluctuating workloads.</p>
<h6><strong>Access to a Global Talent Pool</strong></h6>
<p>Hiring freelancers opens up a vast pool of talent from around the world, increasing your chances of finding the perfect match for your project.</p>
<h5><strong>Cons of Hiring Freelancers</strong></h5>
<p>But there are also challenges:</p>
<h6><strong>Less Control</strong></h6>
<p>Managing freelancers can be more challenging due to the lack of direct oversight, which can affect project quality and timelines.</p>
<h6><strong>Potential for Communication Issues</strong></h6>
<p>Working with remote freelancers can lead to communication barriers, especially if there are significant time zone differences or language barriers.</p>
<h6><strong>Varying Commitment Levels</strong></h6>
<p>Freelancers juggle multiple projects, which might affect their availability and commitment to your project.</p>
<h4><strong>Comparing In-House and Freelance Options</strong></h4>
<h5><strong>Cost Comparison</strong></h5>
<p>When comparing costs, in-house developers often require a higher financial investment due to ongoing salaries and benefits. Freelancers, while generally more cost-effective, may have higher hourly rates but lack the additional overhead costs.</p>
<h5><strong>Quality and Consistency</strong></h5>
<p>In-house teams often provide consistent quality due to their deep integration within the company. Freelancers, on the other hand, may offer varied quality depending on their workload and other commitments.</p>
<h5><strong>Communication and Collaboration</strong></h5>
<p>In-house teams benefit from face-to-face communication, which fosters better collaboration. Freelancers rely on virtual communication tools, which can sometimes hinder effective collaboration.</p>
<h5><strong>Long-term vs. Short-term Projects</strong></h5>
<p>For long-term projects, in-house developers might be more beneficial due to their ongoing commitment. Freelancers are ideal for short-term or one-off projects where flexibility and cost savings are prioritized.</p>
<h4><strong>Making the Right Choice for Your Project</strong></h4>
<h5><strong>Assessing Your Project Needs</strong></h5>
<p>Begin by evaluating the specific needs of your project. Consider the complexity, duration, and required expertise. Determine whether ongoing support and maintenance will be necessary.</p>
<h5><strong>Budget Considerations</strong></h5>
<p>Analyze your budget constraints and allocate resources accordingly. If financial flexibility is limited, freelancers might be the more viable option. For larger budgets, investing in an in-house team can yield long-term benefits.</p>
<h5><strong>Project Timeline</strong></h5>
<p>Assess the urgency of your project. In-house developers can provide quicker turnarounds due to their immediate availability, while freelancers might have varying schedules.</p>
<h5><strong>Future Scalability</strong></h5>
<p>Consider the future growth of your project. In-house teams are better suited for scalable projects that require ongoing development and support. Freelancers can handle immediate needs but might not be ideal for long-term scalability.</p>
<h4><strong>Conclusion</strong></h4>
<p>In conclusion, <a title="hiring Laravel developers" href="https://www.aistechnolabs.com/hire-laravel-developers">hiring Laravel developers</a> is a strategic decision that can significantly impact the success of your web development projects. By choosing skilled and experienced Laravel developers, you ensure the creation of high-quality, scalable, and secure web applications that meet your business needs. Whether you opt for in-house developers or freelancers, careful consideration of your project requirements, budget, and long-term goals is essential. Ultimately, hiring Laravel developers can provide a competitive edge and drive your business towards technological excellence.</p>
<h2> </h2>
<p><strong>FAQs</strong></p>
<h5><strong>Q: What is the main difference between in-house and freelance Laravel developers?</strong></h5>
<p>A: The primary difference lies in their employment status. In-house developers are full-time employees of your company, while freelancers are independent contractors working on a project-by-project basis.</p>

1,915,333 | Must-Have Skincare Products for Rainy Weather! | Hello, fellow skincare lovers! 🌧️ Rainy days are such a mood, but they can also be a really big enemy... | 0 | 2024-07-08T07:06:32 | https://dev.to/iliana_williams_c6ae095c3/must-have-skincare-products-for-rainy-weather-5eij | Hello, fellow skincare lovers! 🌧️ Rainy days are such a mood, but they can also be a really big enemy of your skin. This time of the year, the weather can be quite humid and the conditions appear and disappear often; therefore, you have to be alert and change your usual skincare regime. Let's take a look at the best skincare products for the drizzling rainy days that are actually the source of your radiance.
## Why Skincare in Rainy Weather is a Big Deal!
The weather of the rainy days may lead to increased production of sebum rendering the skin very oily, which may cause the appearance of acne and other skin problems that are quite annoying and challenging for both men and women. The right skin care products which are meant to treat your skin type directly and to deal with the cruel foxes of the rainy season are extremely useful in maintaining your beauty.
### A Nourishing Moisturiser for Skin
Do you think that you can manage to skip a moisturiser while it's pouring? Well, I don’t think so. A moisturiser for skin is a must-have essential on such days. Go for lightweight, oil-free, and aqua-based ingredients that add a small amount of moisture to your face without clogging your pores. The best choice is gel-based ones that will save your skin from being greasy and still keep it moisturised.
PRO TIP: Just because you have oily skin, do not rest assured that a moisturiser is a big no for you. You ought to keep your skin nourished with a specialised [moisturiser for oily skin](https://skinq.com/products/moisture-balm-50-ml-moisturizer-for-dry-skin).
### Gel-Based Sunscreen
Cloudy with the sun doesn't mean you can stay away from the SPF; it is vital to use a gentle sun protective cream every time. Besides the natural rays of the sun, the addition of UV light to the skin due to clouds can cause skin damage. A [gel-based sunscreen](https://skinq.com/products/sun-protect-gel-spf-40-with-vitamin-c-sunscreen-cream) means you have a supportive invisible pal during the wet weather. Such a sunscreen is not a greaser and is quickly absorbed by your skin.
### A Niacinamide Face Wash!
Cleansing your face is very important, especially when the weather is wet. A rich niacinamide face wash that helps in the regulation of skin oil, reducing inflammation and keeping breakouts at bay becomes the bare necessity of the season. Niacinamide (also known as Vitamin B3) works wonders for your skin and soothes your skin. Therefore such a [face cleanser](https://skinq.com/collections/cleansers) is the best choice for oily and acne-prone skin.
## More Tips for Rainy Weather Skincare
### Exfoliate Like a Pro
Eliminating dead skin cells from the surface and getting rid of the clogged pores is an inevitable exercise one must follow, especially during monsoon! Exfoliating 2-3 times per week is very effective in keeping your skin smooth and clear, which is very essential when the rainy season comes.
### Hydrating Serums
Boost your hydration game with a good serum. Look for something with hyaluronic acid to keep your skin plump and moisturised, even in the humidity.
### Ditch the Heavy Makeup
Heavy makeup + humid weather = disaster. Stick to lightweight, non-comedogenic products that let your skin breathe and stay breakout-free.
## Wrapping It Up:
Monsoon is one of the most amazing times of the year. You definitely want to enjoy the rainfall with a cup of hot brewed coffee and tempting snacks. But do not forget to bless your skin too with the essential products it needs to feel pampered during this time. Through the use of these effective tips and suitable skincare products, glowing skin even on rainy days is guaranteed! Let's stay fabulous and let the glow last forever✨!

This article will give an extensive overview of every ServiceNow version, including the most current updates, prior releases, and upcoming releases. Keep up with ServiceNow's development and promote ongoing user improvement in your businesses.
## Exploring the History of ServiceNow Versions
ServiceNow has been around for more than ten years. It was first released in 2007 under the name "Summer 2007" by the firm, which had just rebranded themselves from Glidesoft. A periodic release plan was then implemented, resulting in the annual release of up to three separate versions of ServiceNow. Between 2007 and 2011, ServiceNow versions were called by the seasons in which they were launched rather than following a city-based naming scheme. Among these releases were:
1. Summer 2007
2. Fall 2007
3. Summer 2008
4. Winter 2009
5. Spring 2009
6. Fall 2009
7. Spring 2010
8. Winter 2011
9. Spring 2011
The naming scheme for ServiceNow versions was modified to adhere to a new pattern after these versions. The revised method assigns a city-based identification to each edition, which is then arranged alphabetically.

It involves associating each piece of data with a label from a set of possible labels (or categories). In the simplest cases, there are only two categories, known as binary or binomial classification. Otherwise, it is multi-class classification, also called multiclass classification.
The categories must be determined before any form of learning. Additionally, the data used for learning must all receive a label, allowing the expected response to be known: this is supervised learning. While in the majority of cases each piece of data will be associated with only one class, there are some particular cases, such as:
- **Multilabel classification**: each piece of data can be associated with multiple classes.
- **Object detection in images**: this involves not determining the class of an image as a whole but recognizing the different objects present and their respective positions.
- **Image segmentation**: a specific case of detection, it involves indicating for each pixel to which class it belongs. Pixels of the same class are generally associated with the same color.
**Practical Examples**
Although the most common example in the literature is determining whether an image contains a cat or a dog, classification is used in many more realistic and useful everyday domains:
- **In industry**: it allows determining whether a product has defects or if a part needs replacement (predictive maintenance).
- **On e-commerce sites**: it can automatically associate a category with a product based on its description or determine if a product is fraudulent.
- **In security**: it can determine if there is fraud, if an email is spam, or if a site is potentially dangerous.
- **With connected objects**: it can determine if the monitored element is in a normal state or not, and therefore if intervention is needed or if there is a risk of future problems, such as a pending avalanche.
Many problems can thus be reduced to a classification problem.
**Specific Data Preparation**
The classification task does not impose constraints on the explanatory variables, although some algorithms may have additional requirements. However, the target variable, which corresponds to the class to be predicted, must necessarily be a categorical variable (ordinal or nominal). Additionally, in practice, the number of classes must remain small compared to the number of examples. Indeed, since classification is based on statistics on existing data, it is important to have many examples of each class.
There is no rule to determine in advance the ideal number of cases per class. This will depend heavily on the algorithm, the proximity of data within the same class, and the distance between data associated with different classes. | moubarakmohame4 |

title: "I know your Password"
date: "2024-07-07"
author: "thomas"
description: "I know your passwords, **ALL** of them. Or I can download them if I want to. The reason is because of Silicon Valley wants to spy on your whole online life."
---
I have written about [Silicon Valley corruption](https://ainiro.io//blog/supabase-versus-magic-you-win) before. Most people probably think such corruption is not relevant for them. However, most people are wrong.
Some few days ago [10 billion passwords were leaked](https://siliconangle.com/2024/07/07/new-rockyou2024-password-dump-raises-global-cybersecurity-alarms/). This implies purely mathematically that you have to assume your online life is compromised. 10 billion passwords is more passwords than people on earth, implying the statistical probability of that your password is in there is probably 99.99%.
This allows me to download the above password file, find your username, and create a script that allows me to login to every single online account you've ever created in some 10 hours - Without even breaking a sweat!
## A solved problem
Leaking passwords in 2024 is quite frankly preposterous. There are no reasons why Silicon Valley startups shouldn't use secure password storage systems, such as BlowFish hashing with individual per-record based salts. Storing passwords such that they're impossible to access is a _"5 minute job"_ in 2024. Still, 98% of every single Silicon Valley startup cannot figure out how to store your passwords securely.
This is true to such an extent that it's almost impossible to fathom. Even Facebook had a password leak some 5 years ago, at which point the world could see that Facebook was storing passwords in clear text. The fix is literally a 5 minute job may I add. Below is some pseudo code that fixes it in 5 minutes ...
```javascript
// Assumes workload 10
if (dbPassword.startsWith('$2b$10$')) {
// Password is already hashed.
return blowFishVerify(passwordArg);
} else {
// Password is not hashed.
if (dbPassword === passwordArgs) {
// Updatibng old password by hashing it.
// To trap edge cases add a try catch around the next line of code.
saveNewPassword(blowfish(dbPassword));
return true;
}
return false;
}
```
The above is 10 lines of code, and can be implemented to intercept authentication requests, resulting in that you _"automagically"_ update all old passwords during the first login attempt. It's literally a 5 minute job applying the above code to your existing codebase. For bonus points, you can create a scheduled task iterating all existing passwords in the database, hashing all those that haven't already been hashed.
However, for some weird reason, 99% of every single Silicon Valley startup that ever existed was too lazy to implement the above, which makes you wonder why they're obsessed with having access to _your_ passwords in clear text ...
> Are Silicon Valley software developers using your passwords to spy on you ...?
Because quite frankly, there exists no other reasons explaining this behaviour in 2024 ...
## How AINIRO protects you
At AINIRO we've (ofc) done what no other startup have been bothered to do, which is to store your passwords 100% secure. To prove that fact I'll publicly show you my own password.
> $2b$10$nizBSsYoLDq/5P4vlw/7R.CyNeTHAQj5TSQ8tz2hGUEjPKYzXz6nW
The point being that the above is in fact _not_ my password, but a BlowFish hashed version of my password, with a per record based salt and a workload of 10 - Making it impossible for a super computer to find its actual value, even if it had 1 billion years at its disposal. At AINIRO we store _all_ passwords using BlowFish. This is an algorithm that of course nobody in Silicon Valley could be bothered to implement, because according to their own slogan they are ...
> _"Moving fast and breaking stuff"_
And when they're breaking stuff that's not even theirs, they couldn't care less I assume - So they basically _never_ fix it. For the record, if you need a Low-Code and No-Code solution that stores passwords the right way, you can use our [Magic Cloud](https://ainiro.io/magic-cloud), allowing you to rapidly implement secure storage of passwords in case you're too inexperienced to implement `blowFishHash` yourself.
## How passwords are stolen
Passwords are stolen by malicious hackers breaking into systems such as Facebook, Twitter, LinkedIn, and GMail, etc. Then they gain access to the password database. Most such password database systems are storing their passwords in clear text. Storing passwords in clear text is such a huge violation of security best practices, that there should exist a special place in hell for developers still doing this.
But because Silicon Valley startups are, quote; _"Moving fast and breaking stuff"_, most Silicon Valley companies are still storing passwords in clear text. In fact, I'm willing to bet a kidney on that if I was to analyse the codebase of every single YC funded company the last 36 months, probably 50% of these are storing passwords in clear text. It's simply easier for them, and if something bad happens, it's not their problem - So why should they care ...?
## You can Sue the VC Company
90% of all Silicon Valley startups the last decade were funded by the same VC companies, Sequioa, YC, and the other usual suspects. As I demonstrated in my previous article, these companies are swimming in money - And they're partially owned by some of the richest people on earth.
This allows you to sue these companies for having conducted themselves in such a way that malicious hackers found your password, and used it to impersonate you, possibly stealing money from you, and/or doing other types of harm towards you.
> You can literally sue the richest companies and investors on the planet, and your chance of winning would be quite large too, assuming you can prove the password came from their database, and you experienced losses due to the leak
And why should you care if you drive them bankrupt? It's not like as if they cared about your password, right ...?
## How to set a Trap
Creating a password leak trap is actually quite easy, just register at some Silicon Valley startup and chose a password such as for instance; _"fg%54DFGfgfThisPasswordIsOnlyUsedAtReddit_com"_. Then wait for the _next_ leak, search through its passwords, and see if you can find your password. If you can, you know for a fact the password leak originated from Reddit, and you can sue Reddit for having endangered your online life.
Notice, I've got no idea if Reddit stores passwords in clear text, they're merely used as an example.
By registering at 100+ different YC startups using passwords such as the above, you can probably sue 50+ companies the next time passwords are leaked, and you can be expected to win _every single lawsuit_, becoming rich in the process.
## Conclusion
Ignoring the fact that you should never reuse your passwords, and that you should chose long passwords, with at least 12 characters, preferably 20 - The problem is systemic. Today fixing the issue is so easy that I cannot imagine any other reasons for Silicon Valley startups still violating this simple best practice besides that they _want to access your password to spy on you_.
However, you really don't have to put up with it. Sue the living crap out of them. They only understand _one_ language anyway, and that's money! If you get to their wallets they'll change ...
> Sue like **CRAZY**!

Well, buckle up, because I've got a story for you.
It all started with localization. I was working on my mobile app - [Social AIde](https://apps.apple.com/app/social-aide/id6504584869) _(an AI powered social-media response generator app built in Swift, thanks to AI because I never touched Swift before)_.
I wanted to add a bunch of new languages, but everything was hardcoded. Yikes 😬
The problem wasn't finding the hardcoded strings, but replacing them with keys for a key-value pair JSON file. Fun times, right?
Copy-pasting 200+ strings manually? _No thanks._
There had to be a better way.
Spoiler: There wasn't.
At least, not in the VS Code marketplace. I looked for plugins, I tried to search online, but I was stuck with manually copying the string, then copying back the key.
I'm too lazy to that.
So I turned to my trusty sidekick, good friend, Claude AI.
Described my problem:
```
Please help me creating a visual studio code macro/extension, whatever fits my use case. Here's what it should do:
You select a hardcoded text in the editor, and initiate the plugin (maybe as a command, called "replace with localized string key". It would ask for what should be the key (in a prompt?)
Then it replaces the selected text with that key in this format: String(localized: "my_key")
Then add/modify a JSON file in the project's root folder to add the key and the original hardcoded string in a key-value pair.
```
In 4 seconds it laid out everything: how to start a VS Code extension, what code to add:
Mind. Blown 🤯.
No Googling required – just follow the instructions.
But why stop there? I figured, _"Hey, let's make this available to everyone!"_
So I asked Claude to add configuration options. Boom. Done.
Then came the publishing process: API keys, descriptions, licenses – Claude had me covered.
Of course, every cool extension needs a logo.
So I quickly jumped to recraft.ai and asked for a vector image of a _"magnifying glass zooming in on an arrow pointing up"_.
So the only manual thing left was to take a screen recording (because all cool VSCode plugins have a nice gif animation) - of course Claude helped me how to insert it into the readme (which was also written by Claude btw).
Just like that, in less than an hour, I had a [Hardcoded String Replacer VS Code extension](https://marketplace.visualstudio.com/items?itemName=johnnyfekete.hardcoded-string-replacer) live.
Zero prior experience required.
It's wild how AI is making our jobs faster.
Sure, you still need a basic understanding, but those entry barriers? They're crumbling.
So here's to AI, our new coding buddy. Making the impossible possible, one accidental project at a time.
Who knows? Your next "oops, I made a thing" moment might be just around the corner. | johnnyfekete |
