This will be a web-based assistant and could be the beginning of your own AI project. It’s beginner-friendly, and I will guide you through it step-by-step. By the end, you’ll have your own AI assistant!
## What You’ll Need
- IDE (I recommend Visual Studio Code)
- Gemini API key
- Python
- Python libraries
## Download IDE — VS code
You can use any IDE you like, but if you don’t have one, please download VS Code. It’s really powerful and easy to use. Here’s the link: https://code.visualstudio.com/download
## Gemini API
### Create a Google Cloud Project
Before we obtain an API key, we need to create a project in Google Cloud. To create a project, please follow this link: https://console.cloud.google.com/cloud-resource-manager
After the project is created, we are ready to request an API key.
### How to Get Gemini API Key
To get the API key, visit https://aistudio.google.com/app/apikey and click on the “Create API key” button.
Then, select the project that you created in the previous step from the drop-down menu and click “Generate API key”.
Copy the key; we’ll need it in the next steps.
## Install Python
Windows: Download the installer from https://www.python.org/downloads/windows/
Linux (Ubuntu/Debian): Use this command in your terminal window:
```
sudo apt-get install python3
```
## Install Python Libraries
For the next steps, you need to use the terminal. If you are on Windows, you can use https://apps.microsoft.com/detail/9n0dx20hk701?rtc=1&hl=en-us
### Install PIP
After we set up Python, we need to set up the pip package installer for Python.
```
sudo apt install python3-pip
```
### Set Up a Virtual Environment
The next step is to set up virtual environments for our project to manage dependencies separately.
Use this command:
```
sudo apt install python3-venv
```
The command python3 -m venv myprojectenv is used to create a virtual environment for a Python project:
```
python3 -m venv myprojectenv
```
The command source myprojectenv/bin/activate is used to activate the virtual environment:
```
source myprojectenv/bin/activate
```
### Install LangChain
LangChain is a framework designed to simplify the creation of applications using large language models.
Use this command:
```
pip install langchain-core
```
### Install LangChain-Google-GenAI
Use this command:
```
pip install langchain-google-genai
```
This package contains the LangChain integrations for Gemini through their generative-ai SDK.
Once you’ve done that, we are ready to go to the next steps.
### Install Flask
Once the virtual environment is activated, we can use pip to set up Flask.
Use this command:
```
pip install Flask
```
Create a ChatBot with the Python Flask Framework
First, let’s create a directory for our app.
Use these commands:
```
mkdir myflaskapp
```
```
cd myflaskapp
```
Inside the directory, create a file for our app and call it “app.py”.
Then add the following content:
```
from flask import Flask
app = Flask(name)
@app.route('/')
def home():
return "Hello, Flask!"
if name == 'main':
app.run(debug=True)
```
To make sure that our app is working fine, let’s run it.
Use this command:
```
python3 app.py
```
If everything is okay, you will be able to access your Flask app at http://127.0.0.1:5000.
## Create an HTML Page for the Flask App
You can create your own HTML or use the example provided.
You can download it from here: [https://github.com/proflead/gemini-flask-app/blob/master/web/index.html](https://github.com/proflead/gemini-flask-app/blob/master/web/index.html)
You will need 2 JavaScript files:
To communicate with the Gemini API: [https://github.com/proflead/gemini-flask-app/blob/master/web/gemini-api.js](https://github.com/proflead/gemini-flask-app/blob/master/web/gemini-api.js)
And [https://github.com/proflead/gemini-flask-app/blob/master/web/main.js](https://github.com/proflead/gemini-flask-app/blob/master/web/main.js) To format the output result on the page without reloading the page.
### Change app.py
Let’s modify our app.py file with the following code:
You can copy the code from here: [https://github.com/proflead/gemini-flask-app/blob/master/app.py](https://github.com/proflead/gemini-flask-app/blob/master/app.py)
Once you are ready, run this command in the project folder:
```
python3 app.py
```
If you did everything correctly, you will be able to see your ChatBot.

1,883,309 | Using AI to improve security and learning in your AWS environment. | Why We're Building a Chatbot: Empowering Our Platform Team Our Platform engineers are the... | 0 | 2024-06-10T13:57:00 | https://dev.to/monica_escobar/using-ai-to-improve-security-and-learning-in-your-aws-environment-p90 | ## Why We're Building a Chatbot: Empowering Our Platform Team
Our Platform engineers are the backbone of our secure development process. However, they often face hurdles that slow them down and hinder their ability to deliver top-notch work. On top of this, there are different levels of expertise within the team and consulting all the available documentation can be a daunting and time consuming task. This chatbot could potentially reduce the coaching workload from the senior members to the junior members of the team.
To address these challenges and empower the teams, I chose to build a chatbot specifically designed to assist them.
Our team’s stack is composed of Airflow and Spark mainly, as well as the infrastructure hosted in AWS.
Here's a closer look at the pain points we're aiming to solve:
* Streamlining Security Testing: Finding potential security vulnerabilities in code can be a time-consuming task. The chatbot will help engineers identify issues quickly and efficiently, it can trigger automated security scans through Spark or Airflow jobs, analyze scan results from S3 buckets, and present findings to engineers in a user-friendly way. This has become even more prominent and needed now with GDPR regulations. It can become a good tool for detecting PII data especifically tailored to our environment, if for whatever reason, Amazon Macie is not on the cards.
* Enhancing Security Visibility: the team needs a clear picture of potential software vulnerabilities across all applications, like out of support versions. The chatbot can leverage data from various sources, like security reports stored in S3 buckets, and use this information to identify trends and potential vulnerabilities across applications managed by your EC2 instances within VPCs.
* Heavy teaching workload: having an easy accesible but secure chatbot to consult all the platform’s documentation, fully tailored to our environment, will positively impact everyone in the team. Junior members will become more independent and confident in what they do and senior members will have more time to spend working on their own tickets.
* Simplifying Security Practices: Developing strong threat models and security policies is crucial, but it can be complex. The chatbot will offer guidance and best practices, making it easier for engineers to implement these essential safeguards.
* Boosting Infrastructure Security: Infrastructure as Code (IaC) plays a vital role in our development process.The chatbot can leverage tools like CloudFormation or Terraform to identify potential security risks within IaC templates before deployment to EC2 instances.
* Enforcing Security Pipelines: Integrating security checks seamlessly into our development pipelines is essential. The chatbot will help enforce these checks, guaranteeing that security is never an afterthought by triggering security scans within Airflow pipelines, ensuring vulnerabilities are identified and addressed before code is deployed to production instances behind your ELBs.
* Ensuring Quality Control: We are committed to delivering high-quality solutions. The chatbot will provide us with valuable insights and data, enabling us to maintain a high level of control over the development process.
By building this chatbot, we're investing in building secure and reliable software, as well as promoting a continuous learning culture and self development.
Here's a detailed breakdown of the steps I followed to build our chatbot:
Step 0:
Use the following CloudFormation template to deploy all the resources.
{% embed https://github.com/Thetechyteacher/ai-chatbot.git %}
Step 1: Adding Documents to Amazon Simple Storage Service (S3)
* What it is: Amazon S3 is a secure, scalable object storage service that acts as the foundation for our chatbot's knowledge base.
* The Why: You'll store essential documents like security best practices, threat model templates, and IaC security guidelines in S3. This documents will be specific to your own production environment, so the answers can be fully tailored to our requirements. I personally chose to feed it with Spark and Airflow documentation, as well as general security docs.
* How to do it:
1. Create an S3 bucket: This acts as a virtual folder where you'll store your documents.
2. Upload relevant documents: Upload security policies, best practice guides, and any other resources you might need.
3. Configure access permissions: Ensure the chatbot has the necessary permissions to access and retrieve information from the S3 bucket.
Step 2: Searching with Amazon Kendra
* What it is: Amazon Kendra is an intelligent search service that allows users to easily find relevant information across various sources like S3 buckets.
* The Why: Kendra will be crucial for your chatbot to efficiently search the vast amount of security information stored in S3.
* How to do it:
1. Create a Kendra index: This index tells Kendra where to look for information, in this case, your S3 bucket containing security documents.
2. Add an s3 connector and link it to the s3 bucket which contains the data.
3. Sync now.
Step 3: Setting Up Access to Amazon Bedrock
* What it is: Amazon Bedrock is a security configuration language that helps enforce security best practices throughout your infrastructure.
* The Why: The chatbot can leverage Bedrock (AI) to guide chatbot users (our engineers) in developing secure IaC configurations and identify potential security risks in their code.
* How to do it:
1. You will need access to Anthrotopic (Claude) and Titan Express. If you don’t have it granted yet, you’ll need to request it now.
Step 4: Using SageMaker Studio IDE to Build Your Chatbot
* What it is: SageMaker Studio IDE is a cloud-based integrated development environment (IDE) designed for building and deploying machine learning models.
* The Why: SageMaker Studio provides the tools and resources you need to develop your chatbot's core functionality, including natural language processing (NLP) and dialogue management capabilities.
* How to do it:
1. Choose an appropriate Large Language Model (LLM): LLMs are AI models trained on massive amounts of text data, forming the foundation for your chatbot's ability to understand and respond to user queries. We will be using Claude and Titan Express.
2. Train the LLM on your security knowledge base: This involves feeding the LLM with the documents stored in S3, allowing it to learn the specific language and concepts related to DevSecOps security.
3. From the terminal, git clone the following repo: git clone https://github.com/aws-samples/generative-ai-to-build-a-devsecops-chatbot/
4. From the terminal, you will have to export Kendra’s Index ID, like this:
export KENDRA_INDEX_ID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
5. Install requirements:
pip install -r requirements.txt pip install -U langchain-community
6. And use streamline to design your script’s interface by running the following command: streamlit run app.py titan
7. Get the URL from this page and remove the /lab path. Instead, add this: /proxy/8501/
8. Navigate to that URL and you will see your own chatbot live and running, how exciting!
NOTE: If you want to use Claude run this command instead: streamlit run app.py claudeInstant
* Why would you want to test different LLM?
Different LLMs have varying strengths and weaknesses. Testing with multiple options helps identify the LLM that best understands the terminology and delivers the most accurate and helpful responses.
Step 5: Remember to clean up your resources to avoid any potential charges.

[In 2023, cloud IT infrastructure spending was around 105 billion dollars](https://www.statista.com/statistics/503686/worldwide-cloud-it-infrastructure-market-spending/#:~:text=In%202023%2C%20cloud%20IT%20infrastructure%20spending%20is%20expected%20to%20reach%20some%20105%20billion%20U.S.%20dollars.). These stats represent that businesses understand the importance of the cloud. Cloud computing is defined as a service that allows users to access computing resources such as servers, storage, databases, and other features on an as-needed basis. Further integration of cloud computing with operating systems and IoT shall open up more business possibilities and improve technological systems in the future. Moreover, edge computing brings data processing closer to the sources that generate data, minimizing delays, saving bandwidth resources, and improving the rate of real-time decisions made. This makes it a rather valuable outcome aimed at further enhancing the potential of IT infrastructure.
### Blockchain and Serverless Computing:
Blockchain technology’s decentralized, unalterable, and transparent structure transforms conventional IT support by providing secure databases, smooth interoperability across organizations, and reliable track and trace. On the other hand, serverless computing facilitates back-end services on an as-used basis or the Function as a Service (FaaS) model, so developers do not need to worry about managing servers or backend infrastructure. It transforms the management of IT infrastructures by abstractly handling servers, minimizing costs, and improving scalability, thus providing a better way of developing and implementing improved solutions for business processes.
## Conclusion:
In Conclusion, we stand on the verge of a world where digital transformation will be enhanced using IT infrastructure and its features, such as edge computing, IoT, scalability, and more. The future of digitalization is looking bright with advanced technologies like AI, blockchain, and machine learning.
The impacts will be more extensive and widespread in businesses like healthcare, education, fintech, etc. However, with more benefits, we must also look out for the probable challenges, address them, and find solutions for smooth and effective business operations and processes.

For this experiment, I also use the power of V0.dev, which provides an artificial intelligence to create components React or pure HTML with Tailwind CSS.
## Creating the UI using V0
Enter in the [v0.dev](https://v0.dev/) and put a prompt with the idea of the UI you want, in this case, I put:
> A clean snackbar com title, description and a button in the right side
### Step 1
### Step 2
### Step 3
That's it, thanks v0 and Tailwind CSS 🥰
## Structure used to organize
You are free to organize your own idea, but in my experience, I use:
### /components
Seems obvious, but this is where I store my components.
### /components/models
The file `snackbar.ts` is used to export the interface used on the component.
``` typescript
export interface SnackbarOptions {
visible: boolean;
title?: string;
description?: string;
}
```
Often when we create a new component with the Angular CLI, we have these files:
- snackbar.component.html
- snackbar.component.ts
- snackbar.component.spec.ts
- snackbar.component.scss
To create the state of the component, I included a new file called `snackbar.state.ts`, which contains the initialization of the signal.
``` typescript
import { signal } from '@angular/core';
import { SnackbarOptions } from './models/snackbar';
export const InitialState: SnackbarOptions = {
visible: false,
};
export const SnackbarState = signal(InitialState);
```
Now we need to put the template of the component in the place of the application (generally where we have the `<ng-outlet>` if you work with routes), this strategy with Signals is possibly due to the nature of Signal, we can easily listen to the changes of a signal using `effect()` inside the `constructor()`.
In this example, I used the `main.ts` file:
``` typescript
@Component({
selector: 'app-root',
standalone: true,
imports: [SnackbarComponent],
template: `
<main>
@if(snackbar) {
<snackbar
[title]="snackbar.title"
[description]="snackbar.description"
[visible]="snackbar.visible"
></snackbar>
}
</main>
`
})
```
This is where the magic happens, using the special method effect, Angular can identify and update the value of a signal:
``` typescript
export class App {
snackbar: SnackbarOptions | undefined;
constructor() {
effect(() => {
this.snackbar = SnackbarState();
});
}
}
```
To test the Snackbar, we are going to include a method to update the signal, the interest is you are free to update the Snackbar in any place of the application, you should only import the `snackbar.state.ts`, and the Snackbar `effect()` placed in the app will happen, nice isn't it?
``` typescript
handleOpen() {
SnackbarState.update((currentSnackbar) => {
return {
...currentSnackbar,
visible: true,
title: 'LinkedIn',
description: 'Amazing, it works fine!',
};
});
}
```

1,883,293 | Handling SQLite DB in Lambda Functions Using Zappa | Using SQLite is rather straightforward for managing quick services, but when it gets scalable and a... | 0 | 2024-06-10T13:41:07 | https://dev.to/tangoindiamango/handling-sqlite-db-in-lambda-functions-using-zappa-4blg | aws, django, programming | Using SQLite is rather straightforward for managing quick services, but when it gets scalable and a point of data integrity, RDBMS should be the choice at hand. While Relational Database Management Systems (RDBMS) like PostgreSQL or MySQL are the go-to choices for production-grade applications, there are scenarios where SQLite can be a viable and convenient option, especially during development or for small-scale projects. Moreover, when deploying a Django application to a Lambda function, it gets tedious to add secret keys just to test a simple app. You'd agree that working with SQLite would be a better option.
Lambda functions are designed to be stateless and ephemeral, making it challenging to use SQLite out of the box. Maybe it's quite straightforward and does support older versions easily, but along the line, you'd possibly run into issues such as deterministic=True which requires a specific version of SQLite. However, with few additional steps, you can seamlessly integrate SQLite with your Django project in Lambda, allowing you to focus on developing and testing your application without the overhead of setting up a full-fledged database.
When deploying Django applications to AWS Lambda functions, the ephemeral nature of the Lambda environment can pose challenges for maintaining persistent data storage. While it's possible to use RDBMS solutions with Lambda, it often requires additional configuration and setup, including managing database credentials, connection strings, and potentially adding external database instances. By using SQLite, you can simplify the deployment process and avoid the complexities associated with traditional RDBMS setups
Issues I came across while trying to use SQLite in Lambda
loss of data once the function execution ends.
Version Requirements: Some advanced features of SQLite, such as deterministic=True in functions, require specific versions of SQLite which may not be available in the Lambda environment.
**Using SQLite with Django in Lambda**
We can deploy our project using the following
To overcome the limitations of SQLite in Lambda, we can use a package called django_s3_sqlite. This allows us to store our SQLite database in an S3 bucket, enabling persistent storage beyond the ephemeral life of a Lambda function.
Install the django_s3_sqlite package:
```
pip install django_s3_sqlite
```
Update your Django settings:
In your settings.py file, update the DATABASES setting to use the django_s3_sqlite engine, and specify the S3 bucket and file name where your SQLite database will be stored:
```
DATABASES = {
'default': {
'ENGINE': 'django_s3_sqlite',
'NAME': f'{s3_file_name}.db',
'BUCKET': f'{s3_bucket_name}',
}
}
```
This configuration allows your Django application to use an SQLite database stored in an S3 bucket, ensuring persistent data storage across Lambda function invocations. Now let's set up Zappa
**Setting Up Zappa**
Zappa makes it easy to deploy Python applications, including Django projects, to AWS Lambda.
Install Zappa
```
pip install zappa
```
Create a zappa_settings.json file with the appropriate Zappa configuration for your project. Here's an example:
```
{
"production": {
"django_settings": "project_dir.settings",
"aws_region": "us-east-1",
"role_name": "zappa-control",
"role_arn": "your_arn_with_needed_access",
"manage_roles": false,
"project_name": "project_name",
"runtime": "python3.8", # note this version
"s3_bucket": "deploy_bucket",
"use_precompiled_packages": false
}
}
```
Note: We use `use_precompiled_packages` set to false to avoid potential compatibility issues with Lambda's environment. This way we can include our own SQlite binary file.
**Handling SQLite Binary in Lambda**
Given the earlier identified condition of Lambda functions being short-lived, we need to download the SQLite binary to run in our Lambda function. This ensures the required SQLite version is available. You can download the appropriate binary file for your Python version from the official SQLite website or from a trusted source.
Once you have the binary file, upload it to your S3 bucket for easy access during deployment.
```
aws s3 cp s3://{S3_BUCKET}/_sqlite3.so /var/task/_sqlite3.so
```
Note: The path `/var/task/` is the root of your Lambda function's execution environment. However, you can also use the project directory you will be pushing to Lambda:
```
aws s3 cp s3://{S3_BUCKET}/_sqlite3.so {LOCAL_PROJECT_ROOT}/_sqlite3.so
```
Note we are using the cli here, while it might pose some challenge to run cli commands from your code into the lamda function you can also utilize boto3 and write the code to do that, but this might require extra information. But an easier way to run cli commands in lambda function is using the AWS Lambda Layers function.
Also, here's a python function using the subprocess module
```
import subprocess
def download_sqlite_binary():
subprocess.run(['aws', 's3', 'cp', 's3://{S3_BUCKET}/_sqlite3.so', '/var/task/_sqlite3.so'])
```
Then, deploy your Django application to AWS Lambda using Zappa:
```
zappa deploy production
```
Voila. Once successful you should see the url provided for the deployed function. And if you test your application you'd notice your data being persistent. Nice Right.
While using SQLite with Django on AWS Lambda offers convenience and simplicity, it's important to consider the limitations and potential trade-offs such as data integrity, scalability, and Lambda limitations. Integrating SQLite with Django on AWS Lambda using Zappa can be a convenient and efficient solution for development, testing, or small-scale projects. However, reading from an S3 file in your Lambda function incurs additional costs. AWS S3 currently offers a free tier that includes 5GB of storage and allows 200,000 GET requests and 2,000 PUT or PATCH requests. With these pricing considerations, for small projects, the overhead is typically minimal compared to the benefits of simplicity and ease of setup. | tangoindiamango |

The journey from uncertainty to relief was made possible by the dedicated team at Francisco Hack.
I had planned a surprise birthday party for my best friend. I had saved up for months to organize the perfect celebration, only to find out that my bitcoin wallet containing the party funds and some other funds I had saved in the wallet worth $110,000USD had been tampered with. The initial excitement and anticipation turned into a frantic search for the missing money, casting a shadow over what was meant to be a joyous occasion. The heartbreak and disappointment I felt was profound, highlighting the harsh reality of how unexpected events can disrupt even the best-laid plans.
Discovering my missing cryptocurrency was a devastating moment, but contacting Francisco Hack proved to be the turning point. Their professionalism and expertise were evident from the start. They guided me through the process with patience and understanding, instilling confidence in their ability to resolve the issue.
Their knowledge of blockchain technology and digital forensics was truly impressive, and their transparent communication kept me informed and reassured throughout the recovery process. Their unwavering commitment to my case paid off when my lost bitcoin was successfully retrieved.
The moment I regained access to my funds was a moment of pure joy. Francisco Hack dedication and expertise transformed what seemed like a hopeless situation into a success story. I am forever grateful for their outstanding service and highly recommend them to anyone in need of cryptocurrency recovery assistance.
Thank you, Francisco Hack, for making the impossible possible and restoring my faith in recovering lost assets.

With the advent of container orchestration tools like Kubernetes, managing containerized applications has become more efficient. However, as the complexity of these applications grows, the need for a more comprehensive management solution becomes apparent. This is where service meshes come into play.
### What is a Service Mesh?
A service mesh is a configurable infrastructure layer for microservices applications that makes it easy to manage service discovery, traffic management, and security. It provides a unified way to manage the communication between microservices, allowing developers to focus on writing code rather than managing the underlying infrastructure.
### Service Mesh Architecture
A service mesh typically consists of the following components:
- **Data Plane**: This is the component responsible for handling the actual traffic between microservices. It is usually implemented using a proxy or a sidecar.
- **Control Plane**: This component manages the configuration and policies for the data plane. It is responsible for service discovery, traffic management, and security.
### Service Mesh Implementations
There are several service mesh implementations available, each with its own strengths and weaknesses. Some of the most popular ones include:
- **Istio**: Istio is an open-source service mesh developed by Google, IBM, and Lyft. It provides a robust set of features for traffic management, security, and observability.
- **Linkerd**: Linkerd is another open-source service mesh developed by Buoyant. It is known for its simplicity and ease of use.
- **Consul**: Consul is a service mesh developed by HashiCorp. It provides a comprehensive set of features for service discovery, traffic management, and security.
Service meshes play a critical role in [platform engineering](www.platformengineers.io) by providing a unified way to manage the communication between microservices. This allows platform engineers to focus on building and maintaining the underlying infrastructure rather than managing the complexities of microservices communication.
### Service Mesh Configuration
Configuring a service mesh involves defining the policies and configurations for the control plane. This can be done using YAML or JSON files. Here is an example of an Istio configuration file:
```yaml
apiVersion: networking.istio.io/v1alpha3
kind: ServiceEntry
metadata:
name: external-svc
spec:
hosts:
- external-svc.example.com
location: MESH_EXTERNAL
ports:
- name: http
number: 80
protocol: http
resolution: DNS
```
This configuration defines a service entry for an external service.
### Service Mesh and Observability
Service meshes provide a comprehensive set of features for observability. They allow developers to monitor and analyze the traffic between microservices, providing insights into the performance and behavior of the application. Here is an example of an Istio configuration file for observability:
```yaml
apiVersion: telemetry.istio.io/v1alpha1
kind: Telemetry
metadata:
name: telemetry
spec:
selector:
matchLabels:
istio: ingressgateway
providers:
- name: prometheus
type: PROMETHEUS
- name: jaeger
type: JAEGER
```
This configuration defines a telemetry configuration for Istio, which allows developers to monitor and analyze the traffic between microservices using Prometheus and Jaeger.
### Conclusion
Service meshes are a critical component of modern containerized applications. They provide a unified way to manage the communication between microservices, allowing developers to focus on writing code rather than managing the underlying infrastructure. By providing features for traffic management, security, and observability, service meshes have become an essential tool for managing complex microservices applications. | shahangita | |

You may... | 0 | 2024-06-10T13:26:37 | https://dev.to/paulike/preventing-extending-and-overriding-4j6p | java, programming, learning, beginners | Neither a final class nor a final method can be extended. A final data field is a constant. You may occasionally want to prevent classes from being extended. In such cases, use the **final** modifier to indicate that a class is final and cannot be a parent class. The **Math** class is a final class. The **String**, **StringBuilder**, and **StringBuffer** classes are also final classes. For example, the following class **A** is final and cannot be extended:
`public final class A {
// Data fields, constructors, and methods omitted
}`
You also can define a method to be final; a final method cannot be overridden by its subclasses.
For example, the following method **m** is final and cannot be overridden:
`public class Test {
// Data fields, constructors, and methods omitted
public final void m() {
// Do something
}
}`
The modifiers **public**, **protected**, **private**, **static**, **abstract**, and **final** are used on classes and class members (data and methods), except that the **final** modifier can also be used on local variables in a method. A **final** local variable is a constant inside a method. | paulike |
1,883,248 | Why Can’t We Use async with useEffect but Can with componentDidMount? | React is full of neat tricks and some puzzling limitations. One such quirk is the inability to... | 0 | 2024-06-10T13:26:01 | https://dev.to/niketanwadaskar/why-cant-we-use-async-with-useeffect-but-can-with-componentdidmount-45be | javascript, react, programming, beginners | React is full of neat tricks and some puzzling limitations. One such quirk is the inability to directly use `async` functions in the `useEffect` hook, unlike in the `componentDidMount` lifecycle method of class components. Let’s dive into why this is the case and how you can work around it without pulling your hair out!
## **The Basics: Why `useEffect` Doesn't Like async Functions**
**Function Signature:**
- What `useEffect` Wants: It expects its callback to return either nothing (undefined) or a cleanup function.
- What `async` Gives: An `async` function always returns a Promise, which doesn’t fit the return expectations of `useEffect`.
**Cleanup Function:**
- In `useEffect`: If you need to perform cleanup (like clearing timers, cancelling subscriptions, etc.), you return a cleanup function.
- With `async`: An `async` function cannot directly return this cleanup function because it returns a promise, leaving React unsure of what to do.
**Expected Return Value:**
- `useEffect` Expects: Either `undefined` or a cleanup function.
- `async` Provides: A Promise, which doesn't align with this requirement.
Here's a quick summary: `useEffect` wants either nothing or a cleanup function, but an `async` function always returns a Promise. Imagine ordering a coffee and getting a promise to deliver it someday—useEffect is just not cool with that.
## **The Difference with componentDidMount**
**Lifecycle Methods:**
- `componentDidMount`: Called after the component has rendered and the DOM is ready. You can use `async` functions within `componentDidMount` because it doesn’t have the same requirement for a cleanup function.
- `useEffect`: Designed to handle side effects (like data fetching, subscriptions, or DOM manipulations) in functional components. Since `useEffect` expects a cleanup function, using an async function directly would lead to unexpected behavior.
**Synchronous Nature:**
- `componentDidMount`: Inherently synchronous. You can call an async function within it to perform side effects without needing to return a cleanup function.
- `useEffect`: Expects a cleanup function, so using async directly leads to unexpected behavior.
## **Recommended Approaches: The Workarounds**
Since useEffect and async functions don’t mix well, here are some ways to handle async operations without causing React to throw a tantrum.
**1. Immediately Invoked Function Expression (IIFE)**
Wrap your async logic inside an IIFE to keep your useEffect callback synchronous.
```
useEffect(() => {
(async () => {
const data = await fetchSomeData();
console.log(data);
})();
}, []);
```
**2. Separate Function Declaration**
Declare the async function inside the effect and then call it.
```
useEffect(() => {
const fetchData = async () => {
const data = await fetchSomeData();
console.log(data);
};
fetchData();
}, []);
```
**3. Cleanup Example**
Handle cleanup within the async function and ensure it runs synchronously.
```
useEffect(() => {
let isMounted = true;
const fetchData = async () => {
const data = await fetchSomeData();
if (isMounted) {
console.log(data);
}
};
fetchData();
return () => {
isMounted = false;
};
}, []);
```
## **Conclusion**
Understanding why `useEffect` doesn't mesh well with `async` functions helps you write cleaner, more efficient React code. Remember, the trick is to keep the `useEffect` callback synchronous and handle async operations inside it. By wrapping your async logic properly, you can sidestep this quirky limitation and keep your side effects under control.
Happy coding, and may your React components be ever snappy and bug-free! And remember, just like React, sometimes life gives you a Promise—you just need to handle it right! | niketanwadaskar |

I learned the hard way about the importance of threat modeling and having backups._
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
[OWASP® Cornucopia 2.0](https://github.com/OWASP/cornucopia/releases/tag/v2.0.0)
Today, as one of the co-leaders for OWASP® Cornucopia together with Colin Watson and and Grant Ongers, I am very proud to share that we finally, with lots of help from contributors, supporters and backers and OWASPs hardworking employees are releasing OWASP® Cornucopia 2.0.
Why is this important and why should you care about this? First of all, as Adam Shostack would put it..
> “You never are going to have a better time than when people are having fun and talking to you.”
OWASP® Cornucopia is a threat modeling tool in the form of a card game to assist software development teams identify security requirements in Agile, conventional and formal development processes. It strives to be language, platform and technology-agnostic.
It’s one of the few tools that connects threat modeling with OWASP ASVS, MASVS, MASTG, SAFECode, SCP and CAPEC and helps to identify security requirements, come up with a security design and a threat model without any prior knowledge of any of this.
**_How? OWASP® Cornucopia is open, democratic and agile, and that’s why it works._**
At Admincontrol, we had been struggling for quite a while to get all our teams to do regularly threat-modeling sessions. It’s not that we weren’t able to do them it’s more that we didn’t see **active participation** during our threat modeling sessions. Either I would be the only one talking or I would be the only one coming up with threats and mitigations during the threat modeling sessions.
The initiative always had to come from me. If I didn’t take the initiative for the sessions, they wouldn’t happen. But we thought that it’s not like everybody has the same experience and knowledge about threat modeling.
Perhaps the teams lack training and knowledge about threat modeling? Perhaps it’s normal that not everybody can’t participate equally?
So we tried to increase and spread the knowledge about threat modeling, but no matter what we would do, it wouldn’t change the nature of the sessions.
We did **presentations** on threat modeling.
We **trained** security champions in doing threat modeling.
We attended a large amount of **follow-up meetings** and **online sessions** together with the teams.
We did threat-modeling on the **weekly security forums**.
We even submitted ISO 27001 ISMS security incidents on non-compliance to the project managers.
**_At a certain point I just had enough._**
I remember, I was in a session together with one of the teams and It was like I was watching myself from the outside of my body while I was talking, saying the exact same thing I had said 100 times before and I could see one of the poor people participating, falling asleep, while I was talking.
If you have people in the meeting falling asleep, then that is not their fault, doesn’t matter how little they may have slept the night before really, because if you have the people in your meeting engaged and in a dialog with you, then that won’t happen. So that was on me, I had fallen in the trap of starting lecturing the people in the sessions. If anybody here have kids you may have experienced that if you start lecturing them, they very rarely listen, but lecturing adults is not only stupid it’s also disrespectful. If you want engaging and meaningful conversations you need active participation from all parties.
So I wanted participation in the meetings. I wanted the teams to take the initiative and I wanted the people participating to learn something from them and take something with them back.
Now, after having used OWASP® Cornucopia for awhile, I can say that we have a lot more conversations during our threat modeling sessions then we used to. The teams themselves takes the initiative for threat modeling creates the threat models and come up with the threats that they need to mitigate. They take a lot more ownership, not only over the security requirement gathering and security design, but the functional testers have also started to do a lot more penetration testing. We are not that dependent any longer on having an external company doing penetration testing for us, and we are discovering more security issues earlier during development. thereby, reducing time to market and the number of defects found after the release.
From having these Cornucopia sessions we have learned that delegation of security requirement gathering, threat modeling and security planning is possible. The less we intervene, the better the overall quality of the sessions. As we are able to delegate the threat modeling to the teams we get an increased capacity for process improvement, facilitation, and we decrease the time-to-marked and number of production defects. From having these sessions we have also learned that everyone can actively participate regardless of their knowledge and experience, even the QA testers and project managers scores points and win rounds for threats in the game. And it can be fun too!
_**But what about the [OWASP® Cornucopia 2.0 release](https://github.com/OWASP/cornucopia/releases/tag/v2.0.0)?**_
Firstly, the formerly called “Cornucopia — Ecommerce Website Edition” is now called “Cornucopia — Website App Edition”. This edition was originally created in August 2012, released as v1.0 in February 2013 and has previously undergone a number of minor updates/releases in the following ten years. This has been substantially updated in today’s release of v2.0, in which the most noticeable change has been to update the OWASP ASVS mapping from ASVS v3.0 to v4.0. Further work on the data and code to generate the files for the cards themselves, the cases and folded leaflet and the legacy guide document has been undertaken, and this code also generates cards/cases/leaflets in two physical sizes. The smaller is often referred to as “bridge-sized cards” and the larger as “Tarot-sized cards”. All these v2.0 files are immediately available in six languages (EN, ES, FR, NL, NO-NB and PT-BR) due to efforts of past and current volunteers.
Secondly, as a result of other significant effort, there is now a completely new edition for threat modelling mobile apps. This “Cornucopia — Mobile App Edition” is released as v1.0 and is mapped to the OWASP Mobile Application Security Verification Standard (MASVS v2.0) and OWASP Mobile Application Security Testing Guide (MASTG) v1.7, and is available, initially, in one language (EN), and in two physical sizes. Like the original, this completely new edition of Cornucopia also has six suits of 13 cards plus two jokers, with the suit names drawn from MASVS: Platform & Code (PC), Authentication & Authorization (AA), Network & Storage (NS), Resilience (RS), Cryptography (CRM) and Cornucopia (COM).
The new Cornucopia Mobile App Edition 1.0
Both releases also have newly updated case designs.
Two new Cornucopia case designs
Finally, we are releasing a brand new website called “Copi”, available from [https://copi.owasp.org](https://copi.owasp.org) for online collaboration and gaming where you and your team can play both these games even if you are present in different locations.
You can download printable files from [https://github.com/OWASP/cornucopia/releases/tag/v2.0.0](https://github.com/OWASP/cornucopia/releases/tag/v2.0.0)
We thank everyone who has contributed to OWASP® Cornucopia over the years, without whom these latest releases would not have been possible.

**TL;DR:** Learn to bind SQLite data to the Syncfusion WinUI DataGrid, perform CRUD operations, and reflect these changes within the Grid. Key steps include setting up the SQLite connection, defining data models, and implementing UI components for performing CRUD actions.
The Syncfusion [WinUI DataGrid](https://www.syncfusion.com/winui-controls/datagrid "WinUI DataGrid") displays and manipulates tabular data. Its rich feature set includes functionalities like data binding, editing, sorting, filtering, and grouping. It has also been optimized to work with millions of records and handle high-frequency, real-time updates.
[SQLite](https://en.wikipedia.org/wiki/SQLite "Wikipedia: SQLite") is a lightweight, open-source, self-contained relational database management system (RDBMS). Its simplicity and efficiency stand out, making it a popular choice for embedded and mobile apps and desktop software.
In this blog, we’ll see how to bind and populate SQLite data in the Syncfusion WinUI DataGrid, perform CRUD (create, read, update, and delete) actions on the database, and update the changes in the DataGrid.
**Note:** Before proceeding, refer to the [WinUI DataGrid getting started documentation](https://help.syncfusion.com/winui/datagrid/getting-started "WinUI DataGrid getting started documentation").
## Binding SQLite data to the WinUI DataGrid
Let’s bind and populate data regarding contact details from an SQLite database in the Syncfusion WinUI DataGrid control by following these steps:
### Step 1: Install the required packages
Ensure you have installed the necessary packages for the SQLite DB connection in your project. Refer to the following image.
### Step 2: Define the class to access the database
Let’s define the **SQLiteDatabase** class that handles the SQLite connection and table creation. This class utilizes the **SQLiteAsyncConnection** API to manage the database operations.
Now, create a table named **Employee** in that SQLite database. Refer to the following code example.
```csharp
public class SQLiteDatabase
{
readonly SQLiteAsyncConnection _database;
public const string DatabaseFilename = "SQLiteDBActive.db";
public const SQLite.SQLiteOpenFlags Flags =
// Open the database in read/write mode.
SQLite.SQLiteOpenFlags.ReadWrite |
// Create the database if it doesn't exist.
SQLite.SQLiteOpenFlags.Create |
// Enable multi-threaded database access.
SQLite.SQLiteOpenFlags.SharedCache;
public static string DatabasePath =>
Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), DatabaseFilename);
public SQLiteDatabase()
{
_database = new SQLiteAsyncConnection(DatabasePath, Flags);
_database.CreateTableAsync<Employee>();
}
}
```
### Step 3: Create an instance for the SQLite connection
Create a singleton instance for the SQLite connection and initialize it in the **App.Xaml.cs** file to use the database in our business class **ViewModel**.
Refer to the following code example.
```csharp
public partial class App : Application
{
/// <summary>
/// Initializes the singleton app object. This is the first line of authored code
/// executed, which is the logical equivalent of main() or WinMain().
/// </summary>
public App()
{
this.InitializeComponent();
}
static SQLiteDatabase database;
// Create the database connection as a singleton.
public static SQLiteDatabase Database
{
get
{
if (database == null)
{
database = new SQLiteDatabase();
}
return database;
}
}
}
```
### Step 4: Create the Employee class
Next, we define the **Employee** class as a **Model** to hold the property values from the database table columns.
Refer to the following code example.
```csharp
public class Employee : NotificationObject, INotifyDataErrorInfo
{
private double _EmployeeID;
private string _Name;
private string _location;
private string _Title;
private DateTimeOffset? _BirthDate;
private string _Gender;
private bool employeeStatus;
private string _email;
Regex emailRegex = new Regex(@"^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$");
/// <summary>
/// Gets or sets the employee ID.
/// </summary>
/// <value>The employee ID.</value>
[PrimaryKey]
public double EmployeeID
{
get
{
return this._EmployeeID;
}
set
{
this._EmployeeID = value;
this.RaisePropertyChanged(nameof(EmployeeID));
}
}
/// <summary>
/// Gets or sets the last name.
/// </summary>
/// <value>The last name.</value>
public string Name
{
get
{
return this._Name;
}
set
{
this._Name = value;
this.RaisePropertyChanged(nameof(Name));
}
}
/// <summary>
/// Gets or sets the Location.
/// </summary>
/// <value>The location.</value>
public string Location
{
get
{
return this._location;
}
set
{
this._location = value;
this.RaisePropertyChanged(nameof(Location));
}
}
/// <summary>
/// Gets or sets the title.
/// </summary>
/// <value>The title.</value>
public string Title
{
get
{
return this._Title;
}
set
{
this._Title = value;
this.RaisePropertyChanged(nameof(Title));
}
}
/// <summary>
/// Gets or sets the Birth Date.
/// </summary>
/// <value>The BirthDate.</value>
public DateTimeOffset? BirthDate
{
get
{
return this._BirthDate;
}
set
{
this._BirthDate = value;
this.RaisePropertyChanged(nameof(BirthDate));
}
}
/// <summary>
/// Gets or sets the Gender.
/// </summary>
/// <value>The Gender.</value>
public string Gender
{
get
{
return this._Gender;
}
set
{
this._Gender = value;
this.RaisePropertyChanged(nameof(Gender));
}
}
/// <summary>
/// Gets or sets the Employee Status.
/// </summary>
/// <value>The EmployeeStatus.</value>
public bool EmployeeStatus
{
get
{
return employeeStatus;
}
set
{
employeeStatus = value;
this.RaisePropertyChanged(nameof(EmployeeStatus));
}
}
/// <summary>
/// Gets or sets the E-Mail.
/// </summary>
/// <value>The EMail.</value>
public string EMail
{
get { return _email; }
set
{
_email = value;
this.RaisePropertyChanged(nameof(EMail));
}
}
#region INotifyDataErrorInfo
public event EventHandler<DataErrorsChangedEventArgs> ErrorsChanged;
public IEnumerable GetErrors(string propertyName)
{
if (propertyName == "EMail")
{
if (!emailRegex.IsMatch(this.EMail))
{
List<string> errorList = new List<string>();
errorList.Add("Email ID is invalid!");
NotifyErrorsChanged(propertyName);
return errorList;
}
}
return null;
}
private void NotifyErrorsChanged(string propertyName)
{
if (ErrorsChanged != null)
ErrorsChanged(this, new DataErrorsChangedEventArgs(propertyName));
}
[DisplayAttribute(AutoGenerateField =false)]
public bool HasErrors
{
get { return this.EMail == null || !emailRegex.IsMatch(this.EMail); }
}
#endregion
}
```
### Step 5: Populating database data in the ViewModel
Then, populate the data from the SQLite database in the **EmployeeViewModel** class, as shown in the following code example.
```csharp
public class EmployeeViewModel : INotifyPropertyChanged, IDisposable
{
public EmployeeViewModel()
{
PopulateData();
employees = this.GetEmployeeDetails(30);
PopulateDB();
}
private async void PopulateDB()
{
foreach (Employee contact in Employees)
{
var item = await App.Database.GetEmployeeAsync(contact);
if (item == null)
await App.Database.AddEmployeeAsync(contact);
}
}
private ObservableCollection<Employee> employees;
/// <summary>
/// Get or set the Employee Details.
/// </summary>
public ObservableCollection<Employee> Employees
{
get
{
return employees;
}
}
Random r = new Random();
Dictionary<string, string> gender = new Dictionary<string, string>();
/// <summary>
/// Get the Employee Details.
/// </summary>
/// <param name="count"></param>
/// <returns></returns>
public ObservableCollection<Employee> GetEmployeeDetails(int count)
{
ObservableCollection<Employee> employees = new ObservableCollection<Employee>();
for (int i = 1; i <= count; i++)
{
var name = employeeName[r.Next(employeeName.Length - 1)];
var emp = new Employee()
{
EmployeeID = 1000 + i,
Name = name,
Location = location[r.Next(1, 8)],
Gender = gender[name],
Title = title[r.Next(title.Length - 1)],
BirthDate = new DateTimeOffset(new DateTime(r.Next(1975, 1985), r.Next(1, 12), r.Next(1, 28))),
EMail = name + "@" + mail[r.Next(0, mail.Count() - 1)],
EmployeeStatus = r.Next() % 2 == 0 ? true : false,
};
employees.Add(emp);
}
return employees;
}
/// <summary>
/// Populate the data for Gender.
/// </summary>
private void PopulateData()
{
gender.Add("Sean Jacobson", "Male");
gender.Add("Phyllis Allen", "Male");
gender.Add("Marvin Allen", "Male");
gender.Add("Michael Allen", "Male");
gender.Add("Cecil Allison", "Male");
gender.Add("Oscar Alpuerto", "Male");

gender.Add("Teresa Atkinson", "Male");
gender.Add("John Ault", "Male");
gender.Add("Robert Avalos", "Male");
gender.Add("Stephen Ayers", "Male");
gender.Add("Phillip Bacalzo", "Male");
gender.Add("Gustavo Achong", "Male");
gender.Add("Catherine Abel", "Male");
gender.Add("Kim Abercrombie", "Male");
gender.Add("Humberto Acevedo", "Male");
gender.Add("Pilar Ackerman", "Male");
gender.Add("Frances Adams", "Female");
gender.Add("Margar Smith", "Male");
gender.Add("Carla Adams", "Male");
gender.Add("Jay Adams", "Male");

gender.Add("J. Phillip Alexander", "Male");
gender.Add("Michelle Alexander", "Male");
gender.Add("Daniel Blanco", "Male");
gender.Add("Cory Booth", "Male");
gender.Add("James Bailey", "Female");
}
string[] title = new string[]
{
"Marketing Assistant", "Engineering Manager", "Senior Tool Designer", "Tool Designer",
"Marketing Manager", "Production Supervisor", "Production Technician", "Design Engineer",
"Vice President", "Product Manager", "Network Administrator", "HR Manager", "Stocker",

};
string[] employeeName = new string[]
{
"Sean Jacobson", "Phyllis Allen", "Marvin Allen", "Michael Allen", "Cecil Allison",

};
string[] location = new string[] { "UK", "USA", "Sweden", "France", "Canada", "Argentina", "Austria", "Germany", "Mexico" };
string[] mail = new string[] { "arpy.com", "sample.com", "rpy.com", "jourrapide.com" };
public event PropertyChangedEventHandler PropertyChanged;
public void OnPropertyChanged(string propertyName)
{
PropertyChangedEventHandler handler = PropertyChanged;
if (handler != null)
{
var e = new PropertyChangedEventArgs(propertyName);
handler(this, e);
}
}
public void Dispose()
{
Dispose(true);
GC.SuppressFinalize(this);
}
protected virtual void Dispose(bool isDisposable)
{
if (Employees != null)
Employees.Clear();
}
}
```
### Step 6: Define the WinUI DataGrid
In this step, we will define the WinUI DataGrid control to display data from the Employee table in our database. We’ll use the properties and structure of the Employee table to set up the DataGrid.
Refer to the following code example.
```xml
<?xml version="1.0" encoding="utf-8"?>
<Window
x:Class="SQLiteWithWinUIDataGrid.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:SQLiteWithWinUIDataGrid"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:dataGrid="using:Syncfusion.UI.Xaml.DataGrid"
mc:Ignorable="d">
<Grid>
<Grid.Resources>
<local:EmployeeViewModel x:Key="employeeViewModel"/>
</Grid.Resources>
<dataGrid:SfDataGrid DataContext="{StaticResource employeeViewModel}"
x:Name="sfDataGrid"
AllowEditing="True"
AutoGenerateColumns="True">
</dataGrid:SfDataGrid>
</Grid>
</Window>
```
### Step 7: Bind SQLite data to WinUI DataGrid
Then, bind the data from the SQLite database to the WinUI DataGrid control.
```csharp
public sealed partial class MainWindow : Window
{
public MainWindow()
{
this.InitializeComponent();
this.Activated += OnActivated;
}
private async void OnActivated(object sender, WindowActivatedEventArgs args)
{
sfDataGrid.ItemsSource = await App.Database.GetEmployeesAsync();
}
}
```
After executing the previous code examples, we’ll get the following output.
<figure>
<img src="https://www.syncfusion.com/blogs/wp-content/uploads/2024/06/2-Binding-SQLite-data-to-the-WinUI-DataGrid.png" alt="Binding SQLite data to the WinUI DataGrid" style="width:100%">
<figcaption>Binding SQLite data to the WinUI DataGrid</figcaption>
</figure>
## Perform CRUD actions with SQLite database and update in WinUI DataGrid
Let’s see how to perform CRUD actions on the SQLite database and update the changes in the WinUI DataGrid control.
Here, we have the **AddWindow**, **EditWindow**, and **DeleteWindow**, enabling us to add, save, and delete employee details, respectively. To perform such actions on this page, we must implement the code to perform CRUD operations on the SQLite database, and respective windows, as mentioned in the following steps.
### Step 1: Database implementation for CRUD actions
The **SQLite-net-pcl** assembly has pre-defined methods for performing CRUD operations. For database updates, refer to the following code example.
```csharp
public class SQLiteDatabase
{
readonly SQLiteAsyncConnection _database;
public async Task<List<Employee>> GetEmployeesAsync()
{
return await _database.Table<Employee>().ToListAsync();
}
public async Task<Employee> GetEmployeeAsync(Employee employee)
{
return await _database.Table<Employee>().Where(i => i.EmployeeID == employee.EmployeeID).FirstOrDefaultAsync();
}
public async Task<int> AddEmployeeAsync(Employee employee)
{
return await _database.InsertAsync(employee);
}
public Task<int> DeleteEmployeeAsync(Employee employee)
{
return _database.DeleteAsync(employee);
}
public Task<int> UpdateEmployeeAsync(Employee employee)
{
if (employee.EmployeeID != 0)
return _database.UpdateAsync(employee);
else
return _database.InsertAsync(employee);
}
}
```
### Step 2: Implement CRUD actions
The codes to add a new item, edit an item, or delete a selected item have been implemented through the **AddWindow**, **EditWindow**, and **DeleteWindow**, respectively. Also, these windows are integrated through a menu flyout support for record rows of DataGrid.
Refer to the following code example.
```xml
<dataGrid:SfDataGrid DataContext="{StaticResource employeeViewModel}"
x:Name="sfDataGrid"
AllowEditing="True"
ColumnWidthMode="Auto"
AutoGenerateColumns="True">
<dataGrid:SfDataGrid.RecordContextFlyout>
<MenuFlyout>
<MenuFlyoutItem Text="Add" Icon="Add" Click="OnAddMenuClick"/>
<MenuFlyoutItem Text="Edit" Icon="Edit" Click="OnEditMenuClick"/>
<MenuFlyoutItem Text="Delete" Icon="Delete" Click="OnDeleteMenuClick" />
</MenuFlyout>
</dataGrid:SfDataGrid.RecordContextFlyout>
</dataGrid:SfDataGrid>
```
Refer to the following image.
<figure>
<img src="https://www.syncfusion.com/blogs/wp-content/uploads/2024/06/3-Menu-flyout-to-perform-CRUD-actions-in-the-WinUI-DataGrid.png" alt="Menu flyout to perform CRUD actions in the WinUI DataGrid" style="width:100%">
<figcaption>Menu flyout to perform CRUD actions in the WinUI DataGrid</figcaption>
</figure>
Clicking on a menu flyout item will activate the corresponding window for CRUD operations, which is implemented as shown below.
```csharp
private void OnAddMenuClick(object sender, RoutedEventArgs e)
{
AddOrEditWindow addWindow = new AddOrEditWindow();
addWindow.Title = "Add Record";
App.ShowWindowAtCenter(addWindow.AppWindow, 550, 650);
addWindow.Activate();
}
private void OnEditMenuClick(object sender, RoutedEventArgs e)
{
AddOrEditWindow editWindow = new AddOrEditWindow();
editWindow.Title = "Edit Record";
editWindow.SelectedRecord = sfDataGrid.SelectedItem as Employee;
App.ShowWindowAtCenter(editWindow.AppWindow, 550, 650);
editWindow.Activate();
}
private void OnDeleteMenuClick(object sender, RoutedEventArgs e)
{
DeleteWindow deleteWindow = new DeleteWindow();
App.ShowWindowAtCenter(deleteWindow.AppWindow, 200, 500);
deleteWindow.SelectedRecord = sfDataGrid.SelectedItem as Employee;
deleteWindow.Activate();
}
```
### Step 3: Preparing a window to add a new record or to edit a selected record
The **AddOrEditWindow** class implements the UI to add new records with all necessary **Employee** class information and edit the selected record. The window binds controls with information on the selected record to retrieve data for the new or edit an existing record.
Information for creating a new record or editing an existing record can be retrieved with controls available in the window bound with details of the selected record. For edit operations, controls will be populated based on the **SelectedRecord,** which is bound, and for add operations, controls will be loaded with default values since the **SelectedRecord** will be null.
Refer to the following code example.
**AddOrEditWindow.xaml**
```xml
<?xml version="1.0" encoding="utf-8"?>
<Window
x:Class="SQLiteWithWinUIDataGrid.AddOrEditWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:local="using:SQLiteWithWinUIDataGrid"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d">
<Grid Margin="5" x:Name="AddEditGrid">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Center">
<Grid >

<ColumnDefinition Width="150"/>
<ColumnDefinition Width="250"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition />

</Grid.RowDefinitions>
<TextBlock Grid.Column="0" Grid.Row="0" Text="Employee ID:" HorizontalAlignment="Right" VerticalAlignment="Center" />
<NumberBox Grid.Column="1" Grid.Row="0" x:Name="employeeIDTextBox" Text="{Binding EmployeeID}" Margin="5" />
<TextBlock Grid.Column="0" Grid.Row="1" Text="Employee Name:" HorizontalAlignment="Right" VerticalAlignment="Center" />
<TextBox Grid.Column="1" Grid.Row="1" x:Name="employeeNameTextBox" Text="{Binding Name}" Margin="5" />
<TextBlock Grid.Column="0" Grid.Row="2" Text="Employee Mail:" HorizontalAlignment="Right" VerticalAlignment="Center" />
<TextBox Grid.Column="1" Grid.Row="2" x:Name="EmployeeMailTextBox" Text="{Binding EMail}" Margin="5"/>
<TextBlock Grid.Column="0" Grid.Row="3" Text="Employee Birth Date:" HorizontalAlignment="Right" VerticalAlignment="Center" />
<CalendarDatePicker Grid.Column="1" Grid.Row="3" x:Name="EmployeeBirthDatePicker" Date="{Binding BirthDate}" Margin="5" />
<TextBlock Grid.Column="0" Grid.Row="4" Text="Employee Gender:" HorizontalAlignment="Right" VerticalAlignment="Center" />
<ComboBox Grid.Column="1" Grid.Row="4" x:Name="GenderComboBox" SelectedItem="{Binding Gender}" Margin="5">
<x:String>Male</x:String>
<x:String>Female</x:String>
</ComboBox>
<TextBlock Grid.Column="0" Grid.Row="5" Text="Employee Location:" HorizontalAlignment="Right" VerticalAlignment="Center" />
<TextBox Grid.Column="1" Grid.Row="5" x:Name="EmployeeLocationTextBox" Text="{Binding Location}" Margin="5"/>
<StackPanel Grid.Column="1" Grid.Row="6" Orientation="Horizontal">
<Button Content="Save" Click="OnSaveClick" Margin="2" />
<Button Content="Cancel" Click="OnCancelClick" Margin="2"/>
</StackPanel>
</Grid>
</StackPanel>
</Grid>
</Window>
```
Refer to the following image. Here, you can see the UI representation of the window for adding a new record. It loads controls with default values.
The UI representation of the window to edit a selected record will load controls with values from the SelectedRecord, as shown below.
Clicking on the **Save** button in the add or edit window will add a new employee record in the underlying employee record collection if the **SelectedRecord** is empty and will modify the selected employee record with the modified data when the **SelectedRecord** is available.
The implementation for adding a new employee record or editing a selected record through the click operation of the **Save** button in the **AddOrEditWindow.xaml.cs** file is shown below.
```csharp
private async void OnSaveClick(object sender, RoutedEventArgs e)
{
bool isEdit = true;
if (SelectedRecord == null)
{
isEdit = false;
SelectedRecord = new Employee();
}
SelectedRecord.EmployeeID = this.employeeIDTextBox.Value;
SelectedRecord.Name = this.employeeNameTextBox.Text;
SelectedRecord.EMail = this.EmployeeMailTextBox.Text;
SelectedRecord.Gender = this.GenderComboBox.SelectedItem.ToString();
SelectedRecord.BirthDate = this.EmployeeBirthDatePicker.Date;
SelectedRecord.Location = this.EmployeeLocationTextBox.Text;
if (isEdit)
await App.Database.UpdateEmployeeAsync(SelectedRecord);
else
await App.Database.AddEmployeeAsync(SelectedRecord);
this.Close();
}
```
### Step 4: Preparing a window to delete a selected record
The UI for deleting a selected record from the collection is implemented in the **DeleteWindow** class.
Refer to the following code example.
**DeleteWindow.xaml**
```xml
<?xml version="1.0" encoding="utf-8"?>
<Window
x:Class="SQLiteWithWinUIDataGrid.DeleteWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:SQLiteWithWinUIDataGrid"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d" Title="Delete Record">
<Grid>
<StackPanel VerticalAlignment="Center" HorizontalAlignment="Center">
<TextBlock Text="Do you want to Delete the Selected Record?"/>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Center">
<Button Content="Yes" Margin="5" Click="OnYesClick" />
<Button Content="Cancel" Margin="5" Click="OnCancelClick"/>

So far you have used the private and... | 0 | 2024-06-10T13:22:17 | https://dev.to/paulike/the-protected-data-and-methods-12gb | java, programming, learning, beginners | A protected member of a class can be accessed from a subclass. So far you have used the **private** and **public** keywords to specify whether data fields and methods can be accessed from outside of the class. Private members can be accessed only from inside of the class, and public members can be accessed from any other classes.
Often it is desirable to allow subclasses to access data fields or methods defined in the superclass, but not to allow non-subclasses to access these data fields and methods. To accomplish this, you can use the **protected** keyword. This way you can access protected data fields or methods in a superclass from its subclasses.
The modifiers **private**, **protected**, and **public** are known as _visibility_ or _accessibility modifiers_ because they specify how classes and class members are accessed. The visibility of these modifiers increases in this order:
Table below summarizes the accessibility of the members in a class.
Figure below illustrates how a public, protected, default, and private datum or method in class **C1** can be accessed from a class **C2** in the same package, from a subclass **C3** in the same package, from a subclass **C4** in a different package, and from a class **C5** in a different package.
Use the **private** modifier to hide the members of the class completely so that they cannot be accessed directly from outside the class. Use no modifiers (the default) in order to allow the members of the class to be accessed directly from any class within the same package but not from other packages. Use the **protected** modifier to enable the members of the class to be accessed by the subclasses in any package or classes in the same package. Use the **public** modifier to enable the members of the class to be accessed by any class.
Your class can be used in two ways: (1) for creating instances of the class and (2) for defining subclasses by extending the class. Make the members **private** if they are not intended for use from outside the class. Make the members **public** if they are intended for the users of the class. Make the fields or methods **protected** if they are intended for the extenders of the class but not for the users of the class.
The **private** and **protected** modifiers can be used only for members of the class. The **public** modifier and the default modifier (i.e., no modifier) can be used on members of the class as well as on the class. A class with no modifier (i.e., not a public class) is not accessible by classes from other packages.
A subclass may override a protected method defined in its superclass and change its visibility to public. However, a subclass cannot weaken the accessibility of a method defined in the superclass. For example, if a method is defined as public in the superclass, it must be defined as public in the subclass. | paulike |

**Introduction**
Welcome to the wild and wacky world of Java programming! If you’ve ever wondered why Java developers have a special bond with their coffee mugs, or why they occasionally break into spontaneous dance routines while debugging, you’re about to find out.
**The Java 21 Conundrum**
Picture this: Java 21 introduces Unnamed Classes and Instance Main methods. Meanwhile, we’re still stuck on Java 17. It’s like waiting for a software update that never arrives. Maybe the Java team is secretly playing hide-and-seek with us. 🕵️♂️
**Java RAM Usage: A Love Story**
Java’s memory management is like a complicated relationship. It’s that clingy partner who refuses to let go of memory even after the breakup. “I still need those 2 GB, just in case!” says Java, while your laptop cries in agony. 💔
**The Java Developer’s Job Description**
Ever read a job description for a Java front-end developer? It goes something like this:
_J ust A_: Help me, please! I’ve been stuck in this enterprise dev job for the past 5 years, and I’m slowly deteriorating.
_V_: This isn’t a meme. It’s a legitimate call for help.
_A_: AAAAAA…
**Java Use Cases: A Flowchart**
Should you use Java? Let’s consult our handy flowchart:
_Are you building Android apps?_
Yes: Please stop. Use Kotlin. Trust us.
No: Well, then… still no.
Java Developers vs. Python
Imagine a Java developer trying to print “Hello World.” They stare at the screen, contemplating life choices. Meanwhile, the Python developer has already finished a cup of coffee, written a novel, and solved world hunger. 🐍☕
**Errors in Java Projects**
Creating a project with a new Java framework feels like watching a horror movie. The 67 errors you’ve never seen before pop up like unexpected jump scares. You follow a YouTube tutorial step by step, and suddenly, your IDE screams, “Congratulations! You’ve unlocked the ‘Confused Developer’ achievement!” 🎮👻
**Conclusion**
So there you have it—Java, where curly braces multiply like rabbits, memory leaks are the new normal, and every line of code feels like a quest in a fantasy novel. Stay tuned for more adventures in upcoming posts, where we’ll explore Java’s quirks, triumphs, and maybe even decode the secret messages hidden in its error messages. Until then, keep coding, keep laughing, and remember: Java is like a good cup of coffee—it keeps you awake and slightly jittery. ☕😄

1,883,262 | What is Decentralized Application (DApp)? | We all do know about different kind of applications, such as a web app, mobile app, distributed app... | 0 | 2024-06-10T13:17:57 | https://dev.to/whotarusharora/what-is-decentralized-application-dapp-3jcg | webdev, blockchain, web3, learning | We all do know about different kind of applications, such as a web app, mobile app, distributed app and more. But, in the recent years, a new term is coined in the software development market, which is decentralized application or the DApp.
The DApp was originally introduced with the introduction of Web 3.0, as it also runs on blockchain technology. And as we are moving towards the new world wide web, you should understand the fundamentals decentralized application. And to know about it, you don’t have to go anywhere else, as all necessary details are provided in this blog.
So, let’s get started.
## What are DApps?
Before we dive directly to the decentralized applications, it’s essentiality to have a fundamental understanding of the centralized application or software.
So, **centralized application** is a software, whose all operations are defined, handled and monitored by a single entity or authority. These applications are used by everyone on regular basis. The most common example of a centralized app can be any banking, social media, communication, or any other software such as Instagram, WhatsApp, Google Pay and more.
When you closely think about examples of centralized apps, you’ll realize that as a user, you don’t have any control over the data flow. Rest all is handled by the development authority, like Google manages Google Pay, and Meta handles the Instagram.
Now, let’s talk about decentralized applications, a complete opposite of the centralized ones.
A **DApp or a decentralized application** works entirely opposite to the centralized apps. DApp functions on the principles of blockchain technology and are mostly developed for Web 3.0. The features of a DApp can be similar to a normal application, but their logics gets executed using blockchain and smart contracts.
Further, in a DApp, there is no direct authority that handles the operations. Instead of it, multiple nodes participating in the app usage are responsible for every task. Due to this, DApps are considered more transparent, autonomous, and secure.
Thus, when blockchain is the primary pillar, then the app is decentralized, otherwise a centralized one. To know it better, you should also undergo the difference between Web 2.0 vs Web 3.0.
## Pros and Cons of DApps
Following are the top pros and cons of a DApp, that must be known before its development.
**Pros of a decentralized application**
* Each transaction is recorded using a public ledger, enabling easy transaction verification.
* The data is not under the control of a single entity.
* DApps create peer-to-peer to communication channels, enhancing speed, performance and stability.
* There’s no single point of failure. It ensures that resources are available in every scenario.
* Decentralized applications are created as open-source software, due to which development time, cost and efforts are low.
**Cons of a decentralized application**
* Due to open-source nature, the attackers can easily modify them and lead a potential breach.
* The DApp deployment ecosystem is complex and requires hefty resources to support the operations.
* DApps are developed mostly for users of Web 3.0. And as you know, web 3.0 is still not heavily used and because of this the user base lacks, impacting the ROI.
## How DApps Differ From Centralized and Distributed Applications?
If you have thoroughly undergone the very first section of this blog, you must know the difference between a DApp and a centralized app.
A DApp is not handled by a single authority, but by the number of nodes or users utilizing it.
On the other hand, a centralized app is controlled by a single authority. The DApp is mainly considered for Web 3.0, where blockchain is the primary base technology. However, centralized apps are preffered for Web 2.0, which is the current web version.
Now, comes the distributed part.
Here, the term distributed refers to the application architecture, such as microservices, and docker. In such architecture, different services of an application runs on an individual server using its own resources. But, internally, all the services are connected and communicate with each other.
It all depend on your specific requirements, whether you want to use distributed architecture or not. But, it’s concisely clear by professionals that both DApp and centralized app can be deployed on a distributed architecture.
Thus, centralized and DApp can both be distributed application.
## Top Decentralized Application Use Case
According to current development and potential of the blockchain technology, following are the top uses cases of decentralized applications.
**#1: Cryptocurrency Wallets**
We all got to know about cryptocurrency, when Bitcoin came into limelight. You would be glad to know that decentralized applications are used to managed to such digital currency. Whether its dodge coin, Ethereum, Tether, or any such currency, all need a wallet, so that user can send and receive it.
The crypto wallets are built on the basis of DApps and these wallets are non-custodial. It means that only you have to the access to associated private keys, which are used for conducting transactions.
**#2: DEXs**
Decentralized exchanges or DEXs are the primary way of connecting to a crypto wallet and initiate transaction. DEX is accessed through a web browser, which navigates you to the DApp, offering wallet access.
Following it, you reach to the features, allowing participation in lotteries, liquidity pools, NFT sale and purchase, crypto trading and more.
**#3: Social Media Applications**
The social media DApps are utilized for building communities and facilitate connecting with other high-end organizations and individuals. These application work contrastingly to centralized social media platforms. They don’t save your data and not even utilize it for monetization purposes by showing ads and clicking baits.
However, social media platforms built upon DApp principles let you own your data and process it in a secure way.
**#4: Online Games**
The DApp games are designed to facilitate the users with growing the value of their account.
The DApp games let user earn NFTs and play in a metaverse. Following it, the NFTs can be sold to other players or buyers in a marketplace. It help the game players to earn some real money and also connect with other players globally in a digital universe, where they can interact as a physical human being.
It sounds quite Sci-Fi, and in reality, it is much more.
## Wrapping Up
DApps are an avant-garde software solution, that are based on the blockchain technology. Such applications provide you the complete ownership or your data and optimize transparency, security and autonomy.
With the adaption of Web 3.0 and blockchain, the DApp development is taking pretty good rise. And you will see them for sure in the near future. Rest, decentralized applications are quite advanced, and you should understand them to take an edge over competitors.

## Understanding geospatial data types
[Geospatial data](https://www.ibm.com/topics/geospatial-data#:~:text=Types%20of%20geospatial%20data&text=There%20are%20two%20primary%20forms,vector%20data%20and%20raster%20data.) types in SQL databases represent different kinds of location-based information.
- Point: This data type represents a single point on a map, defined by its latitude and longitude coordinates. In everyday life, think of it as marking a specific location, like your house on a map. Real-world applications include mapping customer locations for a delivery service or pinpointing the location of a store for a store locator feature on a website.
- LineString: A LineString represents a connected sequence of points that form a line. It could be a road, a river, or a hiking trail on a map. For example, [LineString data](https://docs.actian.com/ingres/11.2/index.html#page/GeospatialUser/Linestring_Data_Type.htm) can help transportation planners analyze traffic flow along a road network or utility companies plan the route for laying down pipelines or power lines.
- Polygon: A Polygon represents a closed shape formed by a series of connected points, enclosing an area. This could be a city boundary, a park boundary, or a parcel of land. Real-world applications include zoning analysis in urban planning, determining flood zones for insurance purposes, or analyzing land use patterns for environmental conservation efforts.
These geospatial data types enable databases to store and manipulate location-based information, allowing businesses and organizations to make informed decisions based on spatial relationships and patterns in the data.
## Setting Up Geospatial Databases
img src: [saylordotorg.github.io](https://www.google.com/url?sa=i&url=https%3A%2F%2Fsaylordotorg.github.io%2Ftext_essentials-of-geographic-information-systems%2Fs09-02-geospatial-database-management.html&psig=AOvVaw2HNLim48-t95fVVkbySTMZ&ust=1718111319242000&source=images&cd=vfe&opi=89978449&ved=0CAQQjB1qFwoTCIjSv8-N0YYDFQAAAAAdAAAAABAE)
Setting up a[ geospatial database](https://www.oracle.com/ng/autonomous-database/what-is-geospatial-database/) is like giving your regular database a GPS upgrade, allowing it to understand and work with location-based information. Here's how you can do it using two popular options: PostgreSQL with PostGIS and MySQL with spatial extensions.
### For PostgreSQL with PostGIS:
1. Install[ PostgreSQL](https://aws.amazon.com/free/database/?gclid=CjwKCAjwyJqzBhBaEiwAWDRJVNSaEAxOzql9bQ8p1Sjj88tE9XA9JgvLrjfH4j78Yk94dFKQOk8LFxoCrlwQAvD_BwE&trk=9c492f02-02db-4831-96b9-ff48877e069b&sc_channel=ps&ef_id=CjwKCAjwyJqzBhBaEiwAWDRJVNSaEAxOzql9bQ8p1Sjj88tE9XA9JgvLrjfH4j78Yk94dFKQOk8LFxoCrlwQAvD_BwE:G:s&s_kwcid=AL!4422!3!669080204326!e!!g!!postgresql!20433874248!152626089256): Think of it as installing a smart organizer for your data. It's like setting up a toolbox for managing all your information neatly.
2. Add PostGIS Extension**: PostGIS is like a special tool you add to your toolbox that knows how to handle maps and locations. It's like giving your toolbox a GPS tracker.
3. Enable PostGIS: After adding PostGIS, you need to activate it, so your database knows it can handle geospatial data. It's like turning on the GPS feature in your phone.
4. Create Geospatial Tables: With PostGIS enabled, you can create tables in your database that understand location information. It's like adding shelves in your toolbox specifically designed to hold maps and location markers.
#### For MySQL with Spatial Extensions:
1. Install MySQL: Similar to PostgreSQL, you're setting up a place to store all your data. It's like creating a digital filing cabinet.
2. Enable Spatial Extensions: Spatial extensions are like installing a plugin or adding an extra feature to your database. It's like adding a special drawer to your filing cabinet just for maps and location data.
3. Create Geospatial Tables: Once you've enabled [spatial extensions](https://www.cmi.ac.in/~madhavan/courses/databases10/mysql-5.0-reference-manual/spatial-extensions.html), you can create tables in your database that can handle geospatial data. It's like adding folders in your special drawer for organizing different types of maps and location information.
Once your geospatial database is set up, you can start doing cool stuff like finding nearby places, drawing maps, and analyzing patterns in your data. Whether you're planning a city layout, tracking delivery routes, or studying wildlife habitats, having a geospatial database makes it much easier to work with location information in your projects. It's like having a superpowered map in your hands, guiding you to make better decisions and understand the world around you in a whole new way.
## Spatial indexing for performance
[Spatial indexing](https://learn.microsoft.com/en-us/sql/relational-databases/spatial/spatial-indexes-overview?view=sql-server-ver16) is like organizing a huge pile of maps so you can find specific locations quickly. In geospatial data analysis, where you're dealing with lots of location information, spatial indexing is essential for finding what you need fast.
Imagine you have a book with maps of different places, and you need to find a specific location. Without spatial indexing, you'd have to flip through the whole book to find it. But with spatial indexing, it's like having a map index that tells you exactly which page to look at, saving you time and effort.
Spatial indexes work by breaking down the geographic data into smaller sections, each with a unique identifier. When you search for something, the spatial index helps your database quickly narrow down the search to the right section, making the process much faster and more efficient.
Spatial indexing is crucial because it makes querying geospatial data much quicker and easier. It helps your database find nearby locations, calculate distances, and perform other tasks without having to scan through every single piece of data.
To make sure your spatial indexes work well, you need to choose the right type of index, update them regularly, and consider the size and distribution of your data. By following these best practices, you can ensure that your spatial indexes continue to provide efficient access to your geospatial data, making your analysis smoother and more effective.
## Performing spatial Queries
[Performing spatial queries](https://www.qgistutorials.com/en/docs/3/performing_spatial_queries.html) is like asking your database about places on a map. It's a bit like using a search engine, but instead of looking for websites, you're searching for locations. There are different types of spatial queries:
- Contains: This checks if one area completely fits inside another. It's like asking if a park contains a playground.
- Intersects: This helps determine if two areas overlap or touch each other. For instance, you might want to know if two parks share a border.
- Distance: This measures how far apart two points are on a map. It's useful for finding out how long it takes to get from one place to another.
In [SQL](https://aws.amazon.com/what-is/sql/#:~:text=Structured%20query%20language%20(SQL)%20is,information%20in%20a%20relational%20database.), which is a language for talking to databases, you use special commands to perform these spatial queries. They help you find specific information about locations and their relationships with each other. Spatial queries are handy for businesses trying to find nearby stores or customers, or for urban planners trying to understand how different parts of a city interact. They make it easier to make decisions based on location data.
## Geospatial Analysis Functions
Geospatial analysis functions in SQL databases are like special tools that help us understand and work with location-based information. They allow us to measure distances, calculate areas, and perform other tasks related to maps and geography.
For example, let's say you want to find out how far your house is from the nearest grocery store. With geospatial analysis functions, you can easily calculate this distance using the coordinates of both locations.
Similarly, if you're planning a park and want to know how much land it will cover, geospatial analysis functions can help. They allow you to calculate the area of the park by analyzing the shapes and sizes of its boundaries.
These functions are incredibly useful in many real-life situations. For businesses, they help optimize delivery routes, analyze customer locations, and identify new market opportunities. In urban planning, they assist in zoning decisions, transportation planning, and environmental conservation efforts. By leveraging geospatial analysis functions, organizations can make more informed decisions and gain valuable insights from location-based data.
## Advanced Geospatial Analysis Techniques
Advanced geospatial analysis techniques in SQL go beyond basic map calculations. They include cool stuff like geocoding, which is like turning addresses into map coordinates, and reverse geocoding, which does the opposite—turning coordinates into addresses. These techniques help businesses find where their customers are located or locate a place based on its coordinates.
Another advanced technique is raster data analysis, which is like analyzing images on a map to find patterns or understand changes over time. For example, scientists might use raster data analysis to track deforestation in a particular area.
These techniques have many real-world applications. For businesses, they help with targeted advertising, logistics planning, and market analysis. For emergency services, they can pinpoint the location of a caller in need of help. And for environmentalists, they're essential for monitoring changes in ecosystems and natural resources. By using advanced geospatial analysis techniques, organizations can gain deeper insights from location-based data and make smarter decisions.
## Best practices and optimization tips
To make [geospatial queries](https://www.mongodb.com/docs/manual/geospatial-queries/V) faster and more efficient, it's important to organize your data and use the right tools. Think of it like arranging your room to find things quickly. Choose the best way to store your location data, like using specific shelves for maps. Use indexes to create shortcuts for finding locations faster, like bookmarks in a book. Lastly, optimize your queries to ask the right questions, like knowing which page to turn to in a book. By following these tips, you can speed up your geospatial analysis and get the answers you need more quickly.
## Case studies and Real-world examples
Imagine a delivery company using geospatial data analysis to plan the most efficient routes for their drivers. By analyzing traffic patterns and customer locations, they can optimize delivery schedules, saving time and fuel costs. However, challenges like unexpected road closures or changes in customer demand can arise. Through continuous analysis and adaptation, they learn to anticipate these challenges and adjust their strategies accordingly. Similarly, city planners use geospatial analysis to design safer roads and better public transportation systems. By studying traffic flow and urban development patterns, they can address congestion issues and improve overall city infrastructure. These real-world examples demonstrate how geospatial data analysis in SQL helps organizations make smarter decisions and solve complex problems in various fields.
## Conclusion
Geospatial data analysis in SQL helps organizations understand location-based information better. By using tools like spatial queries and optimization techniques, businesses can make smarter decisions and solve problems more effectively, leading to improved operations and better results in various fields.

[This section](https://dev.to/paulike/case-study-on-object-oriented-thinking-3k3c) presented a stack class for storing **int** values. This section introduces a stack class to store objects. You can use an **ArrayList** to implement **Stack**, as shown in the program below. The UML diagram for the class is shown in Figure below.
An array list is created to store the elements in the stack (line 5). The **isEmpty()** method (lines 7–9) returns **list.isEmpty()**. The **getSize()** method (lines 11–13) returns **list.size()**. The **peek()** method (lines 15–17) retrieves the element at the top of the stack without removing it. The end of the list is the top of the stack. The **pop()** method (lines 19–23) removes the top element from the stack and returns it. The **push(Object element)** method (lines 25–27) adds the specified element to the stack. The **toString()** method (lines 29–32) defined in the **Object** class is overridden to display the contents of the stack by invoking **list.toString()**. The **toString()** method implemented in **ArrayList** returns a string representation of all the elements in an array list.
In the program above, **MyStack** contains **ArrayList**. The relationship between **MyStack** and **ArrayList** is _composition_. While inheritance models an _is-a_ relationship, composition models a _has-a_ relationship. You could also implement **MyStack** as a subclass of ArrayList. Using composition is better, however, because it enables you to define a completely new stack class without inheriting the unnecessary and inappropriate methods from _ArrayList_. | paulike |

1,883,252 | Scaling Next.js with Redis cache handler | Let's say you have dozens of Next.js instances in production, running in your Kubernetes cluster.... | 0 | 2024-06-10T13:08:22 | https://dev.to/rafalsz/scaling-nextjs-with-redis-cache-handler-55lh | javascript, nextjs, performance, tutorial | Let's say you have dozens of Next.js instances in production, running in your Kubernetes cluster. Most of your pages use [Incremental Static Regeneration](https://nextjs.org/docs/pages/building-your-application/data-fetching/incremental-static-regeneration) (ISR), allowing pages to be generated and saved in file storage upon a user's first visit. Subsequent requests to the same page are served instantly from the saved version, bypassing regeneration, at least until the set revalidation period expires. Sounds good, right?
Except it does not scale very well.
## Problem
The data is generated but never cleaned up. Moreover, every instance of NextJS uses the same data, duplicated and isolated. Here at [Odrabiamy.pl](http://odrabiamy.pl/), we noticed that all of our k8s instances were taking up to 30GB of storage each. That is a massive amount of data for one node, but what if we have 20 nodes? That would be 600 GB of data, which could easily be shared.
## Possible Solutions
We tried to come up with a solution to this problem, and these were our options:
1. **Use a [Kubernetes persistent volume](https://kubernetes.io/docs/concepts/storage/persistent-volumes/) and share the inside of the `.next` directory**, but it has its cons:
1. Every pod would have read/write access, which could cause massive problems with race conditions between pods. We would have to [write our own cache handler](https://nextjs.org/docs/app/api-reference/next-config-js/incrementalCacheHandlerPath) to make sure everything is stable.
2. A mechanism would be needed to copy the `.next` directory to a shared volume during deployment and, after it is not needed anymore, to delete it.
2. **Use Redis and the existing Next.js config to store all the generated pages** - which turned out to be perfect for us in terms of the required time to implement and the complexity of the solution.
## Next.js and Redis
By default, Next.js uses a file-based cache handler. However, Vercel has published a new config option to customize that. To do this, we have to load a custom cache handler in our `next.config.js`:
```jsx
cacheHandler:
process.env.NODE_ENV === 'production'
? require.resolve('./cache-handler.cjs')
: undefined,
```
We only load it in the production environment, as it isn’t necessary in development mode. Now it is time to implement the `cache-handler.cjs` file. (Note: depending on your npm config, you might need to write this using ES modules.)
We will utilize the [@neshca/cache-handler](https://caching-tools.github.io/next-shared-cache) package, which is a library that comes with pre-written handlers. The plan is to:
- Set Redis as the primary cache handler
- As a backup, use LRU cache (Least Recently Used, in-memory cache)
The basic implementation will be as follows:
```jsx
// cache-handler.cjs
const createClient = require('redis').createClient;
const CacheHandler = require('@neshca/cache-handler').CacheHandler;
const createLruCache = require('@neshca/cache-handler/local-lru').default;
const createRedisCache = require('@neshca/cache-handler/redis-strings').default;
CacheHandler.onCreation(async () => {
const localCache = createLruCache({
maxItemsNumber: 10000,
maxItemSizeBytes: 1024 * 1024 * 250, // Limit to 250 MB
});
let redisCache;
if (!process.env.REDIS_URL) {
console.warn('REDIS_URL env is not set, using local cache only.');
} else {
try {
const client = createClient({
url: process.env.REDIS_URL,
});
client.on('error', (error) => {
console.error('Redis error', error);
});
await client.connect();
redisCache = createRedisCache({
client,
keyPrefix: `next-shared-cache-${process.env.NEXT_PUBLIC_BUILD_NUMBER}:`,
// timeout for the Redis client operations like `get` and `set`
// after this timeout, the operation will be considered failed and the `localCache` will be used
timeoutMs: 5000,
});
} catch (error) {
console.log(
'Failed to initialize Redis cache, using local cache only.',
error,
);
}
}
return {
handlers: [redisCache, localCache],
ttl: {
// This value is also used as revalidation time for every ISR site
defaultStaleAge: process.env.NEXT_PUBLIC_CACHE_IN_SECONDS,
// This makes sure, that resources without set revalidation time aren't stored infinitely in Redis
estimateExpireAge: (staleAge) => staleAge,
},
};
});
module.exports = CacheHandler;
```
But here is one interesting caveat. What if Redis isn’t available during server start? The line `await client.connect();` will fail, and the page will load with a delay. But because of this, Next.js will try to initialize a new CacheHandler every time someone visits any page.
That is why we decided to use only LRU in such cases. However, the solution to this problem is not trivial, as `createClient` doesn’t throw errors; it operates only on callbacks. So a workaround is needed:
```jsx
...
let isReady = false;
const client = createClient({
url: process.env.REDIS_URL,
socket: {
reconnectStrategy: () => (isReady ? 5000 : false),
},
client.on('error', (error) => {
console.error('Redis error', error);
});
client.on('ready', () => {
isReady = true;
});
await client.connect();
...
```
This ensures that Next.js will not try to reconnect if the initial connection fails. In other cases, reconnection is desired and works like a charm.
## Performance and stability
Our performance tests showed that CPU usage increased by about 2%, but response times stayed the same.
At Odrabiamy, our goal is not only to have a performant solution but also to have independent infrastructure layers, so that any failure does not influence the functioning of the entire application. This is where the Least Recently Used (LRU) cache comes into play as a crucial fallback mechanism. During our performance tests, we manually terminated Redis multiple times, which resulted in **zero downtime**. The transition between Redis and the LRU cache was so seamless that it wasn’t even noticeable in our performance graphs.
## Conclusion
In the case of multiple Next.js instances running on a Kubernetes cluster, it is worth considering replacing the default file-system based cache with a Redis one. This can free up your storage resources without any risks and performance downgrades. Setting this configuration up is quite easy and was already battle-tested in our production environment. | rafalsz |

Being cognizant of obsolete technology and modernizing through advanced architectures such as [AWS Graviton architecture (Arm processor)](https://aws.amazon.com/ec2/graviton/), makes it possible to reveal more nuanced problems. This helps keep your systems current and in tune for the performance and cost optimization actions that [AWS Graviton migration](https://aws.amazon.com/ec2/graviton/getting-started/) provides.
**Trapped with Legacy x86: Between Comfort and Opportunity**
1. Inertia and Stability: This is because people are inclined to believe that the x86 environments are steadfast and easy to comprehend, hence many organizations are reluctant to move to the new operating environments. When everything is functioning smoothly, the urgency for change isn't felt.
2. Backward Compatibility: This type of argument can be referred to as the ‘double-edged sword’ since it often serves two masters; the purpose behind it is usually achieved at the cost of another.
Backward compatibility is also one of the key assets that can be attributed to x86 architectures. This makes it possible to use older software to operate on newer machines despite the lack of changes. Although this can be useful in the short-term, this creates a vicious cycle where organizations and firms can remain bound to outdated software, inhibit the process of improving and enhancing these applications, and expose themselves to risks.
Here's an example of how you might inventory current versions and evaluate the need for upgrades:
3. Resistance to Change: Changing from Intel x86 processor to Arm processor core means that users enter unknown space. Compatibility challenges, performance and operation issues combined with the fear of possible slowdowns can be quite a discouraging and daunting element to anyone willing to engage in change. Nonetheless, the move to AWS Graviton processor is a well-established process by now, with many businesses having already experienced this transition. Subject to comprehensive support from AWS and specialist partners, the migration can be smooth, thus, while reducing these risks greatly.
**Risks of Outdated Architectures Lurking in the Shadows**
1. Security Vulnerabilities: The continued use of old software versions on x86 architecture entails a considerable security risk for any organization experiencing cyber-attacks and data leakage. Exposed flaws give attackers the liberty to exploit such vulnerabilities.
2. Performance Degradation: This trend showcases that the longer the time between the creation of the legacy x86 architectures and modern options, the larger the performance difference becomes. Old version software is heavy and requires a lot of shop space, time, and system resources that cause slow down.
3. Compatibility Challenges: This incompatibility stems from the fact that as technology progresses, original x86 applications are less compatible with today’s architectural structures and specific programming languages. This results in dependencies that are difficult to overcome and stagnate the progress of technological innovations and advancement.
**Journey to Modernization with AWS Graviton**
1. Architectural Paradigm Shift: AWS Graviton requires an uncomplicated switch to Amazon’s chips with actual application modifications to deal with new architecture. Incorporating [Arm processor architecture](https://www.arm.com/partners/aws) opens up extra capabilities of performance and power conservation.
2. Leveraging ARM's Power: Arm architecture which has logged itself as energy efficient and sound performer gives us a peep into the latest options of computing. Ultimately, AWS Graviton instances enable companies to unlock the full potential of Arm and place them on the cutting edge.
3. Security Fortification: Graviton use in AWS not only improves the performance of the processors but also increases security. One must seek solace in the core security measures hard-wired within the Arm architectures which comprise robust defense against cyber threats.
**A Cost-Effective Modernization Solution**
Distinct from other application modernization projects that could be costly and time-consuming, the migration to AWS Graviton offers an opportunity for organizations to undertake a cost-effective strategy. Effectiveness and productivity can be achieved through the means of improved migratory tendencies also not only to save costs and minimize non-essential expenditures but also to help liberate resources. AWS Graviton price and effort for migration pays for itself in the costs that you will save! AWS Graviton processors offer up to a 40% better price performance than x86 processors and help you reach your sustainability goals.
Conclusion: When it comes to application modernization, organizations face a pivotal choice: fall back to familiar x86 designs or unlock the full potential of AWS Graviton. While x86 can give a sense of security and stick with the tried-and-true, AWS Graviton shows a way for greater advancement, and optimization along with safety. Thus, to pursue AWS Graviton transformation, a company undertakes an optimization process based on technological perspectives and future opportunities to be safer and more efficient.

1,883,247 | Day 9 - Deep Dive in Git & GitHub for DevOps Engineers | 1.What is Git and why is it important? Git is a distributed version control system that is widely... | 0 | 2024-06-10T13:02:58 | https://dev.to/oncloud7/day-9-deep-dive-in-git-github-for-devops-engineers-bck | devops, github, git, 90daysofdevops | **1.What is Git and why is it important?**
Git is a distributed version control system that is widely used in software development to manage source code and track changes made to it over time.
Basically, Git allows developers to collaborate on software projects in a highly organized and structured way. With Git, developers can create their own local working copy of a project, make changes to it, and then merge those changes back into the central repository. Git makes it easy to keep track of which changes were made by whom, when they were made, and why they were made.
**Here are a few reasons why Git is important:**
**Collaboration:** Git makes it easy for developers to collaborate on projects, even if they are located in different parts of the world. Multiple developers can work on the same codebase simultaneously without interfering with each other's work.
**Version control:** Git gives developers the ability to easily track changes to code over time and revert to earlier versions if necessary. This is important for maintaining the integrity of the codebase and ensuring that changes can be rolled back in case of errors or bugs.
**Branching and merging:** Git allows developers to create branches, which are separate copies of the codebase that can be modified independently. This allows for experimentation and testing of new features without affecting the main codebase. Branches can be merged back into the main codebase once the changes have been tested and approved.
**Integration with other tools:** Git can be integrated with other tools in the software development process, such as continuous integration (CI) servers, issue tracking systems, and code review tools. This allows for a highly automated and streamlined development workflow.
Overall, Git is important because it provides developers with a powerful set of tools for managing code, collaborating on projects, and ensuring the quality and integrity of their work.
**2.What is difference Between Main Branch and Master Branch?**
In Git, "main" and "master" branches are both commonly used to refer to the primary branch of a repository that contains the latest stable and production-ready code. However, there is no functional difference between the two terms and they can be used interchangeably.
The term "master" has historically been used in many software development projects to refer to the main branch. However, this term has been criticized for its potentially problematic connotations, particularly given the ongoing conversation about systemic racism and bias in the tech industry. As a result, many developers are now transitioning to using the term "main" instead of "master" to refer to the primary branch of their Git repository.
Many organizations and projects are now officially adopting "main" as the primary branch name, while others continue to use "master". In either case, the functionality of the branch remains the same regardless of whether it is named "main" or "master".
**3.Can you explain the difference between Git and GitHub?**
Git is a distributed version control system that is used to manage source code and track changes made to it over time. Git provides developers with a powerful set of tools for collaborating on code, maintaining version history, and ensuring the integrity and quality of the codebase.
GitHub, on the other hand, is a web-based hosting service for Git repositories. Essentially, GitHub provides a centralized platform for developers to store and share their Git repositories with others. In addition to hosting Git repositories, GitHub provides a range of features and tools that make it easy for developers to collaborate on code, track issues and bugs, and manage project workflows.
**4.How do you create a new repository on GitHub?**
To create a new repository on GitHub, you can follow these steps:
1.Log in to your GitHub account and click on the "+" icon in the upper right-hand corner of the page.
2.Select "New repository" from the dropdown menu.
3.Enter a name for your repository in the "Repository name" field. This name should be descriptive and memorable, and may include a combination of letters, numbers, and hyphens.
4.Optionally, you can add a description for your repository that describes its purpose, contents, or any other important information.
5.Choose whether your new repository will be public or private. Public repositories are visible to everyone, while private repositories can only be accessed by you and any collaborators you invite.
6.If you have an existing repository that you want to import into GitHub, you can choose the "Import repository" option and follow the prompts to import your code.
7.After you have set your options, click on the "Create repository" button to create your new repository.
**5.What is difference between local & remote repository? How to connect local to remote?**
A local repository is a copy of a Git repository that is stored on the developer's local machine, while a remote repository is a copy of a Git repository that is hosted on a remote server. The primary difference between the two is their location, with the local repository stored on the developer's computer and the remote repository stored on a server accessible via the internet or a local network.
**To connect a local repository to a remote repository, you can follow these steps:**
First, create a new repository on your remote Git server. This server could be GitHub, GitLab, Bitbucket, or any other Git hosting service.
Next, navigate to your local repository on your machine and open up a command-line interface.
Use the following command to add the remote repository to your local repository:
`git remote add origin [remote repository URL]`
This command tells Git to associate the remote repository with the name "origin".
Next, push your local repository to the remote repository using the following command:
`git push -u origin master`
This command tells Git to push the "master" branch of your local repository to the "origin" remote repository.
**Task-1:**
Set your user name and email address, which will be associated with your commits.
To set user name and email address to be associated with commits in Git, use the following commands, replacing the user name and email address with your own:
```
git config --global user.name "Your Name"
git config --global user.email "youremail@gmail.com"
```
**Task-2:**
1.Create a repository named "Devops" on GitHub
2.Connect your local repository to the repository on GitHub.
3.Create a new file in Devops/Day-09.txt & add some content to it
4.Push your local commits to the repository on GitHub

I would like to share a pattern for unit testing that I discovered while reading through the repository of one of our dependencies. It's about testing through object representation.
# Problems with Testing Code
I perceive many problems with testing, but two main ones stand out:
1. It’s difficult to write unit tests that test what they should and don't degrade over time.
2. It’s hard to write unit tests quickly.
Our mindset is to develop features as quickly as possible, even at the cost of sometimes breaking things. We don't have the capacity or appetite for 100% test coverage. This post is for similarly-minded programmers.
Senior developers are here to create well-structured designs and deliver features. Therefore, they don't have time to write good tests and delegate such work to junior colleagues.
Juniors don't know how to properly test code, so they test everything they can think of, as they were taught in school. **What they do is just cover the code in concrete.**
Tests become unreadable in half a year, making it hard to understand what they test. If changes are made to the "concreted code" later, tests break, requiring fixes. If they aren't readable, they can't be fixed, and the test rots – it gets deleted or modified just to pass, and the problem grows.
# How to Write Simple Tests?
Let's look at the test below. A simple test, checking that the items of the following invoice will be as expected. A very simple example, but it takes a moment to decode what exactly it tests.
```python
def test_subscription_with_usage_first_tier(self):
self.subscription.record_usage(quantity=5, created_at=aware_date(2020, 6, 1))
usage_summary_group = self.subscription.get_upcoming_invoice_item_groups(
aware_date(2020, 6, 1), aware_date(2020, 7, 1)
)
self.assertEqual(usage_summary_group.price, Decimal(4.5))
self.assertEqual(usage_summary_group.currency, "CZK")
self.assertEqual(len(usage_summary_group.items), 1)
self.assertEqual(usage_summary_group.items[0].price, Decimal(5))
self.assertEqual(usage_summary_group.items[0].currency, "CZK")
self.assertEqual(usage_summary_group.items[0].quantity, 5)
self.assertEqual(usage_summary_group.items[0].get_discounted_price(), Decimal(4.5))
self.assertEqual(usage_summary_group.items[0].discount_name, "Discount 10%")
self.assertEqual(usage_summary_group.items[0].discount_percent_off, 10)
```
An alternative I offer as a solution is to define a `__repr__` method for such an object that includes all relevant values.
```python
def test_subscription_with_usage_first_tier(self):
self.subscription.record_usage(quantity=5, created_at=aware_date(2020, 6, 1))
usage_summary_group = self.subscription.get_upcoming_invoice_item_groups(
aware_date(2020, 6, 1), aware_date(2020, 7, 1)
)
self.assertEqual(
repr(usage_summary_group),
"<UpcomingInvoiceItemGroup 4.50 CZK: Product - Tier 1 (x5) 5.00 CZK (Discount 10% = 0.50 CZK)>",
)
```
The test below tests the same thing as the first test. The difference is that the second test tests the string representation of the object instead of checking all the attributes.
The second test is much faster to write and significantly easier to read. Writing readable tests is one of the key factors in ensuring that a test doesn't rot over time.
But there's a catch. By not testing the object's attributes, there can be an error in the definition of the `__repr__` method.
This means that such a solution is a tradeoff. By trusting the `__repr__` method, I've written a test that is easy to read and faster to write. However, this could be the difference between having tested code and code for which no test exists.
# Conclusion
If you test your code and have no problems with it, you're probably doing it right. However, if you don't have time to write tests, this solution could provide simple, readable, and maintainable tests.

Often you need to create an array list from an array of objects or vice versa. You can write the code using a loop to accomplish this, but an easy way is to use the methods in the Java API. Here is an example to create an array list from an array:
`String[] array = {"red", "green", "blue"};
ArrayList<String> list = new ArrayList<>(Arrays.asList(array));`
The static method **asList** in the **Arrays** class returns a list that is passed to the **ArrayList** constructor for creating an **ArrayList**. Conversely, you can use the following code to create an array of objects from an array list.
`String[] array1 = new String[list.size()];
list.toArray(array1);`
Invoking **list.toArray(array1)** copies the contents from **list** to **array1**. If the elements in a list are comparable such as integers, double, or strings, you can use the static **sort** method in the **java.util.Collections** class to sort the elements. Here are examples:
`Integer[] array = {3, 5, 95, 4, 15, 34, 3, 6, 5};
ArrayList<Integer> list = new ArrayList<>(Arrays.asList(array));
java.util.Collections.sort(list);
System.out.println(list);`
You can use the static **max** and **min** in the **java.util.Collections** class to return the maximum and minimal element in a list. Here are examples:
`Integer[] array = {3, 5, 95, 4, 15, 34, 3, 6, 5};
ArrayList<Integer> list = new ArrayList<>(Arrays.asList(array));
System.out.println(java.util.Collections.max(list));
System.out.println(java.util.Collections.min(list));`
You can use the static **shuffle** method in the **java.util.Collections** class to perform a random shuffle for the elements in a list. Here are examples:
`Integer[] array = {3, 5, 95, 4, 15, 34, 3, 6, 5};
ArrayList<Integer> list = new ArrayList<>(Arrays.asList(array));
java.util.Collections.shuffle(list);
System.out.println(list);` | paulike |

Now we are ready to introduce a very useful class for storing objects. You can create an array to store objects. But, once the array is created, its size is fixed. Java provides the **ArrayList** class, which can be used to store an unlimited number of objects. Figure below shows some methods in **ArrayList**.
**ArrayList** is known as a generic class with a generic type **E**. You can specify a concrete type to replace **E** when creating an **ArrayList**. For example, the following statement creates an **ArrayList** and assigns its reference to variable **cities**. This **ArrayList** object can be used to store strings.
`ArrayList<String> cities = new ArrayList<String>();`
The following statement creates an **ArrayList** and assigns its reference to variable **dates**. This **ArrayList** object can be used to store dates.
`ArrayList<java.util.Date> dates = new ArrayList<java.util.Date> ();`
The statement
`ArrayList<AConcreteType> list = new ArrayList<AConcreteType>();`
can be simplified by
`ArrayList<AConcreteType> list = new ArrayList<>();`
The concrete type is no longer required in the constructor thanks to a feature called _type inference_. The compiler is able to infer the type from the variable declaration.
The program below gives an example of using **ArrayList** to store objects.
```
package demo;
import java.util.ArrayList;
public class TestArrayList {
public static void main(String[] args) {
// Create a list to store cities
ArrayList<String> cityList = new ArrayList<>();
// Add some cities in the list
cityList.add("London");
// cityList now contains [London]
cityList.add("Denver");
// cityList now contains [London. Denver]
cityList.add("Paris");
// cityList now contains [London, Denver, Paris]
cityList.add("Miami");
// cityList now contains [London, Denver, Paris, Miami]
cityList.add("Seoul");
// cityList now contains [London, Denver, Paris, Miami, Seoul]
cityList.add("Tokyo");
// cityList now contains [London, Denver, Paris, Miami, Seoul, Tokyo]
System.out.println("List size? " + cityList.size());
System.out.println("Is Miami in the list? " + cityList.contains("Miami"));
System.out.println("The location of Denver in the list? " + cityList.indexOf("Denver"));
System.out.println("Is the list empty? " + cityList.isEmpty()); // Print false
// Insert a new city at index 2
cityList.add(2, "Xian");
// Contains [London, Denver, Xian, Paris, Miami, Seoul, Tokyo]
// Remove a city from the list
cityList.remove("Miami");
// Contains [London, Denver, Xian, Paris, Seoul, Tokyo]
// Remove a city at index 1
cityList.remove(1);
// Contains [London, Xian, Paris, Seoul, Tokyo]
// Display the contents in the list
System.out.println(cityList.toString());
// Display the contents in the list in reverse order
for(int i = cityList.size() - 1; i >= 0; i--)
System.out.print(cityList.get(i) + " ");
System.out.println();
// Create a list to store two circles
ArrayList<CircleFromSimpleGeometricObject> list = new ArrayList<>();
// Add two circles
list.add(new CircleFromSimpleGeometricObject(2));
list.add(new CircleFromSimpleGeometricObject(3));
// Display the area of the first circle in the list
System.out.println("The area of the circle? " + list.get(0).getArea());
}
}
```
`List size? 6
Is Miami in the list? True
The location of Denver in the list? 1
Is the list empty? false
[London, Xian, Paris, Seoul, Tokyo]
Tokyo Seoul Paris Xian London
The area of the circle? 12.566370614359172`
Since the **ArrayList** is in the **java.util** package, it is imported in line 2. The program creates an **ArrayList** of strings using its no-arg constructor and assigns the reference to **cityList** (line 8). The **add** method (lines 11–21) adds strings to the end of list. So, after
**cityList.add("London")** (line 11), the list contains
`[London]`
After **cityList.add("Denver")** (line 13), the list contains
`[London, Denver]`
After adding **Paris**, **Miami**, **Seoul**, and **Tokyo** (lines 15–21), the list contains
`[London, Denver, Paris, Miami, Seoul, Tokyo]`
Invoking **size()** (line 24) returns the size of the list, which is currently **6**. Invoking **contains("Miami")** (line 25) checks whether the object is in the list. In this case, it returns **true**, since **Miami** is in the list. Invoking **indexOf("Denver")** (line 26) returns the index of **Denver** in the list, which is **1**. If **Denver** were not in the list, it would return **-1**. The **isEmpty()** method (line 27) checks whether the list is empty. It returns **false**, since the list is not empty.
The statement **cityList.add(2, "Xian")** (line 30) inserts an object into the list at the specified index. After this statement, the list becomes
`[London, Denver, Xian, Paris, Miami, Seoul, Tokyo]`
The statement **cityList.remove("Miami")** (line 34) removes the object from the list. After this statement, the list becomes
`[London, Denver, Xian, Paris, Seoul, Tokyo]`
The statement **cityList.remove(1)** (line 38) removes the object at the specified index from the list. After this statement, the list becomes
`[London, Xian, Paris, Seoul, Tokyo]`
The statement in line 42 is same as
`System.out.println(cityList);`
The **toString()** method returns a string representation of the list in the form of **[e0.toString(), e1.toString(), ..., ek.toString()]**, where **e0**, **e1**, . . . , and **ek** are the elements in the list.
The **get(index)** method (line 46) returns the object at the specified index.
**ArrayList** objects can be used like arrays, but there are many differences. Table below lists their similarities and differences.
Once an array is created, its size is fixed. You can access an array element using the square-bracket notation (e.g., **a[index]**). When an **ArrayList** is created, its size is **0**.
You cannot use the **get(index)** and **set(index, element)** methods if the element is not in the list. It is easy to add, insert, and remove elements in a list, but it is rather complex to add, insert, and remove elements in an array. You have to write code to manipulate the array in order to perform these operations. Note that you can sort an array using the **java.util.Arrays.sort(array)** method. To sort an array list, use the **java.util.Collections.sort(arraylist)** method.
Suppose you want to create an **ArrayList** for storing integers. Can you use the following code to create a list?
`ArrayList<int> list = new ArrayList<>();`
No. This will not work because the elements stored in an **ArrayList** must be of an object type. You cannot use a primitive data type such as **int** to replace a generic type. However, you can create an **ArrayList** for storing **Integer** objects as follows:
`ArrayList<Integer> list = new ArrayList<>();`
The program below gives a program that prompts the user to enter a sequence of numbers and displays the distinct numbers in the sequence. Assume that the input ends with **0** and **0** is not counted as a number in the sequence.
The program creates an **ArrayList** for **Integer** objects (line 8) and repeatedly reads a value in the loop (lines 14–19). For each value, if it is not in the list (line 17), add it to the list (line 18). You can rewrite this program using an array to store the elements rather than using an **ArrayList**. However, it is simpler to implement this program using an **ArrayList** for two reasons.
- First, the size of an **ArrayList** is flexible so you don’t have to specify its size in advance. When creating an array, its size must be specified.
- Second, **ArrayList** contains many useful methods. For example, you can test whether an element is in the list using the **contains** method. If you use an array, you have to write additional code to implement this method.
You can traverse the elements in an array using a foreach loop. The elements in an array list can also be traversed using a foreach loop using the following syntax:
`for (elementType element: arrayList) {
// Process the element
}`
For example, you can replace the code in lines 22-23 using the following code:
`for (int number: list)
System.out.print(number + “ “);` | paulike |

1,883,238 | How to identify a phishing Email in 2024 | Sarah was scrolling through her email inbox when a subject line caught her eye: "Exclusive Discount... | 0 | 2024-06-10T12:48:53 | https://blog.learnhub.africa/2024/06/10/how-to-identify-a-phishing-email-in-2024/ | security, cybersecurity, beginners, programming | Sarah was scrolling through her email inbox when a subject line caught her eye: "Exclusive Discount on Your Dream Vacation!" Intrigued, she opened the email, which claimed to be from a well-known travel company she had booked with before.
The email promised an incredible 75% off her next vacation package if she acted quickly and clicked the provided link.
Sarah excitedly clicked the link without a second thought, eager to secure the too-good-to-be-true deal. However, instead of being redirected to the travel company's website, she found herself on a suspicious-looking page requesting her personal and financial information.
Find out how to [Build Your First Password Cracker](https://blog.learnhub.africa/2024/02/29/build-your-first-password-cracker/)
Then, Sarah realized she had fallen victim to a cleverly crafted phishing scam. The email was not from the travel company at all but rather from cybercriminals attempting to steal her sensitive data by exploiting her desire for a discounted vacation.
Phishing attacks have become one of the most prevalent cybersecurity threats, posing significant risks to individuals and organizations.
According to the latest Phishing Activity Trends Report by the [Anti-Phishing Working Group](https://apwg.org/trendsreports/) (APWG), phishing attacks have skyrocketed in recent years. In the first quarter of 2024 alone, the APWG observed a staggering 1.2 million unique phishing sites, a 20% increase compared to the previous year. This alarming trend underscores the urgency of addressing this cybersecurity threat head-on.
As cybercriminals become more sophisticated in their tactics, everyone must stay vigilant and learn how to identify and mitigate these malicious attempts.
In this comprehensive guide, we'll explore the world of phishing emails, provide real-time data statistics, and provide actionable steps to protect yourself from these insidious attacks.
Phishing attacks have evolved beyond the traditional email scams, targeting various platforms, including social media, instant messaging, and even voice phishing (vishing) attacks. The financial sector remains the most targeted industry, accounting for 34.5% of all phishing attacks, closely followed by cloud service providers (29.1%) and online retailers (18.7%).
## How Phishing Email Works
Phishing emails can come in many forms, ranging from seemingly legitimate-looking messages to blatant attempts at deception. However, several red flags can help you identify these malicious emails:
- **Urgency and Scare Tactics**: Phishing emails often create a sense of urgency or fear, pressuring you to act quickly. They may claim that your account has been compromised or that you must verify your personal information immediately.
Also, like Sarah, you might miss out on a discount that is usually too good to be true, which might never be true, as our minds are programmed not to want to miss out, and we lose more.
- **Suspicious Sender**: Pay close attention to the sender's email address. Legitimate organizations typically use their official domain, while phishing emails may use spoofed or similar-looking domains.
Always look at the URL (Uniform Resource Locator). All the scammer needs is to change google.com to googla.com
- **Generic Greetings:** Legitimate companies typically address you by name or username. Phishing emails often use generic greetings like "Dear Customer" or "Valued Member."
While the scammer might be sending to multiple people at once, look if you are BCC (Blind copy) if you see that you are most likely being phished.
- **Spelling and Grammar Mistakes**: While not a foolproof indicator, phishing emails frequently contain spelling and grammar errors, which reputable organizations typically avoid.
Mostly, novices or beginners tend to make mistakes when writing scam emails; if you notice even one spelling error, then it might be a scam.
- **Suspicious Links and Attachments:** Hover over any links or attachments to reveal their destination or origin. Phishing emails may use URLs or attachments that appear legitimate but lead to malicious sites or contain malware.
Never click on any link unless you are sure of its destination. Copy the link location and drop it on Google.
- **Requests for Sensitive Information**: Reputable organizations will never ask through email for sensitive information like passwords, credit card numbers, or Social Security numbers.
Never assume anyone would love to help you sort your financial or bank issues over the internet, and never be too lazy to call or visit the bank directly.

## Common types of phishing attacks
1. **Email Phishing**: This is the most traditional form of phishing, where attackers send fraudulent emails designed to trick recipients into revealing sensitive information or clicking on malicious links or attachments.
Here, attackers rely on you to click a link, which takes you to a fraudulent website where you are asked to submit your details.
1. Spear Phishing: A targeted form of phishing aimed at specific individuals or organizations, often using personalized information to appear more convincing.
2. Vishing (Voice Phishing): Phishing attacks conducted over the phone, where attackers use social engineering tactics to manipulate victims into revealing sensitive information.
3. Smishing (SMS Phishing): Phishing attempts via text messages often contain malicious links or prompt recipients to call a fraudulent number.
4. Angler Phishing: A phishing attack that combines email and malicious websites to steal login credentials, especially targeting online services like webmail or banking.
5. Whaling: A highly targeted form of phishing aimed at high-profile individuals, such as executives or C-suite members.
6. Pharming is a technique where attackers redirect victims to fake websites, even if they enter the correct URL, by exploiting vulnerabilities in DNS servers or installing malware on the victim's device.
7. AI-Powered Phishing: With the rise of artificial intelligence (AI), cybercriminals are now leveraging AI technologies like natural language processing and generative AI to create highly convincing and personalized phishing emails and messages. AI can analyze a victim's online presence, communication patterns, and interests and then generate highly tailored phishing content that is more likely to bypass detection systems and trick the recipient.
8. Deepfake Phishing: Attackers use deepfake technology to create fake audio or video content featuring trusted individuals within an organization, making phishing attempts even more convincing and difficult to detect.
9. AI-Assisted Social Engineering: AI can also enhance social engineering tactics by analyzing large datasets and identifying potential vulnerabilities or points of leverage that can be exploited in phishing attacks.
As AI capabilities advance, individuals and organizations must stay vigilant and implement robust multi-layered security measures to protect against these increasingly sophisticated phishing attacks.
## Mitigating Phishing Attacks: A Proactive Approach
While identifying phishing emails is crucial, taking proactive measures to mitigate these attacks is equally important. Here are some effective steps you can take:
1. **Implement Robust Email Security Solutions**: Invest in reliable email security solutions that detect and block phishing attempts before they reach your inbox. Solutions like Secure Email Gateways (SEGs) and advanced spam filters can significantly reduce your exposure to phishing attacks.
2. **Enable Multi-Factor Authentication (MFA)**: Implementing MFA adds an extra layer of security by requiring multiple forms of authentication, such as a password and a one-time code sent to your mobile device. This makes it much harder for cybercriminals to gain unauthorized access to your accounts, even if they obtain your login credentials.
3. **Regularly Update Software and Systems:** It is crucial to keep your software and systems up-to-date with the latest security patches and updates. Cybercriminals often exploit known vulnerabilities; timely updates can help close these security gaps.
4. **Educate and Train Employees**: Your employees are often the first line of defense against phishing attacks. Provide regular cybersecurity awareness training to educate them on the latest phishing tactics and best practices for identifying and reporting suspicious emails.
5. **Implement a Robust Incident Response Plan**: A phishing attack may slip through the cracks despite your best efforts. A well-defined incident response plan can help you quickly contain and mitigate the impact of a successful phishing attempt.
6. **Encourage Reporting and Collaboration**: Foster an environment where employees feel comfortable reporting suspicious emails or activities. Collaboration between security teams, IT departments, and end-users is essential for effective phishing prevention and response.

## Staying Vigilant in the Face of Evolving Threats
Phishing attacks continue to evolve, with cybercriminals constantly adapting their tactics to bypass security measures and exploit human vulnerabilities. As we navigate the digital landscape, it's crucial to remain vigilant and adopt a proactive mindset regarding cybersecurity.
By staying informed about the latest phishing trends, implementing robust security measures, and fostering a culture of cybersecurity awareness within your organization, you can significantly reduce the risk of falling victim to these malicious attacks.
Remember, phishing is both a technical and a human challenge. Since attackers rely on your human nature to perpetuate their attacks, careful consideration must be implemented before any online transaction.

1,883,237 | Introduction of HTML | What is HTML? HTML stands for Hyper Text Markup Language HTML is the standard markup... | 0 | 2024-06-10T12:48:34 | https://dev.to/wasifali/introduction-of-html-5ffk | webdev, css, learning, html |
## **What is HTML?**
HTML stands for
Hyper Text Markup Language
HTML is the standard markup language for creating Web pages
HTML describes the structure of a Web page
HTML consists of a series of elements
HTML elements tell the browser how to display the content
HTML elements label pieces of content such as "this is a heading", "this is a paragraph", "this is a link", etc.
## **A Simple HTML Document**
## **Example**
```HTML
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
<h1>My First Heading</h1>
<p>My first paragraph. </p>
</body>
</html>
```
## **Example Explained**
The `<!DOCTYPE html>` declaration defines that this document is an HTML5 document
The `<html>` element is the root element of an HTML page
The `<head>` element contains meta information about the HTML page
The `<title>` element specifies a title for the HTML page (which is shown in the browser's title bar or in the page's tab)
The `<body>` element defines the document's body, and is a container for all the visible contents, such as headings, paragraphs, images, hyperlinks, tables, lists, etc.
The `<h1>` element defines a large heading
The `<p>` element defines a paragraph
## **What is an HTML Element?**
An HTML element is defined by a start tag, some content, and an end tag:
`<tagname>` Content goes here... `</tagname>`
The HTML element is everything from the start tag to the end tag:
```HTML
<h1>My First Heading</h1>
<p>My First paragraph</p>
```
## **The href Attribute**
The `<a>`tag defines a hyperlink.
## **Example**
`<a href="https://www.w3schools.com">Visit W3Schools</a>`
## **HTML Headings**
HTML headings are defined with the `<h1>` to `<h6>` tags.
`<h1>` defines the most important heading.` <h6>` defines the least important heading.
## **Example**
```HTML
<h1>Heading 1</h1>
<h2>Heading 2</h2>
<h3>Heading 3</h3>
<h4>Heading 4</h4>
<h5>Heading 5</h5>
<h6>Heading 6</h6>
```
## **HTML Paragraphs**
The HTML `<p>` defines a paragraph
A paragraph always starts on a new line, and browsers automatically add some white space (a margin) before and after a paragraph.
## **Example**
```HTML
<p>This is a paragraph.</p>
<p>This is another paragraph.</p>
```
## **The HTML Style Attribute**
Setting the style of an HTML element, can be done with the style attribute.
The HTML style attribute has the following syntax:
```HTML
<tagname style="property:value;">
```
## **HTML Formatting Elements**
Formatting elements were designed to display special types of text:
`<b>` - Bold text
`<strong>` - Important text
`<i>` - Italic text
`<em>` - Emphasized text
`<mark>` - Marked text
`<small>` - Smaller text
`<del>` - Deleted text
`<ins>` - Inserted text
`<sub>` - Subscript text
`<sup>` - Superscript text
## **HTML `<blockquote>` for Quotations**
The HTML `<blockquote>` element defines a section that is quoted from another source.
## **HTML `<q>` for Short Quotations**
The HTML `<q>` tag defines a short quotation.
## **HTML `<abbr>` for Abbreviations**
## **Example**
```HTML
<p>The <abbr title="World Health Organization">WHO</abbr> was founded in 1948.</p>
```
## **HTML `<address>` for Contact Information**
## **HTML `<cite>` for Work Title**
## **Example**
```HTML
<p><cite>The Scream</cite> by Edvard Munch. Painted in 1893.</p>
```
## **HTML `<bdo>` for Bi-Directional Override**
BDO stands for Bi-Directional Override.
The HTML `<bdo>` tag is used to override the current text direction:
## **Example**
```HTML
<bdo dir="rtl">This text will be written from right to left</bdo>
```
## **HTML Comment Tag**
You can add comments to your HTML source by using the following syntax:
```HTML
<!-- Write your comments here -->
```
## **Color Values**
In HTML, colors can also be specified using RGB values, HEX values, HSL values, RGBA values, and HSLA values.
The following three <div> elements have their background color set with RGB, HEX, and HSL values:
```HTML
rgb(255, 99, 71)
#ff6347
hsl(9, 100%, 64%)
```
The following two <div> elements have their background color set with RGBA and HSLA values, which add an Alpha channel to the color (here we have 50% transparency):
```HTML
rgba(255, 99, 71, 0.5)
hsla(9, 100%, 64%, 0.5)
```
## **Example**
```HTML
h1 style="background-color:rgb(255, 99, 71);">...</h1>
<h1 style="background-color:#ff6347;">...</h1>
<h1 style="background-color:hsl(9, 100%, 64%);">...</h1>
<h1 style="background-color:rgba(255, 99, 71, 0.5);">...</h1>

1,857,103 | Demystifying AWS Security: IAM Password Policies vs. Automated Access Key Rotation | Are you new to managing security in your AWS environment? Navigating the intricacies of AWS Identity... | 0 | 2024-06-10T12:42:39 | https://dev.to/damola12345/demystifying-aws-security-iam-password-policies-vs-automated-access-key-rotation-4l70 | security, aws, devops | Are you new to managing security in your AWS environment? Navigating the intricacies of AWS Identity and Access Management (IAM) can be overwhelming, especially when it comes to ensuring strong security practices. In this beginner-friendly blog post, we'll explore two fundamental aspects of AWS security: IAM password policies and automatically rotating IAM access keys using a Lambda function.
## IAM Password Policy: Strengthening Your Authentication
Let's start with IAM password policies. These policies define the rules and requirements for user passwords within your AWS account. By enforcing strong password policies, you can significantly enhance the security of your AWS environment. Here's what you need to know:
**_Complexity Requirements:_** IAM password policies allow you to specify complexity requirements such as minimum length, the inclusion of special characters, and the prohibition of common passwords.
**_Password Expiry:_** You can set password expiry periods to ensure that users regularly update their passwords. This helps mitigate the risk of compromised credentials.
**_Preventing Password Reuse:_** IAM password policies can also prevent users from reusing previous passwords, further bolstering security.
By configuring a robust IAM password policy, you establish a strong foundation for authentication security within your AWS account.
## Automatically Rotating IAM Access Keys: Enhancing Key Security
In addition to strong password policies, it's essential to regularly rotate IAM access keys. Access keys are used to authenticate programmatic access to AWS services, and regularly rotating them helps mitigate the risk of unauthorized access. Here's how you can automate this process using a Lambda function:
**_Lambda Function:_** AWS Lambda allows you to run code in response to various triggers. By creating a custom Lambda function, you can automate the rotation of IAM access keys.
**_Key Rotation Logic:_** The Lambda function checks the age of existing access keys associated with IAM users. If a key exceeds a specified age threshold, the function generates a new access key and deactivates the old one.
**_Scheduled Execution:_** You can schedule the Lambda function to run regularly, ensuring that access keys are rotated at predefined intervals without manual intervention.
By automatically rotating IAM access keys, you maintain a higher level of security in your AWS environment and reduce the risk of unauthorized access due to compromised credentials.
**_Conclusion_**
IAM password policies and automated access key rotation are essential components of AWS security. By enforcing strong password policies and regularly rotating access keys, you significantly reduce the risk of security breaches and unauthorized access in your AWS environment. | damola12345 |
1,883,232 | Choosing the Right Web Hosting in 2024: A Cost Breakdown | Website hosting costs depend on your website’s needs and the plan you choose. Here’s a breakdown of... | 0 | 2024-06-10T12:42:30 | https://dev.to/wewphosting/choosing-the-right-web-hosting-in-2024-a-cost-breakdown-1c47 |
Website hosting costs depend on your website’s needs and the plan you choose. Here’s a breakdown of different hosting options and their average prices:
- **Shared Hosting**: Most affordable option (starts at $10/month) ideal for low-traffic websites and blogs. Resources are shared with other websites on the same server.
- **Cloud Hosting**: More reliable than shared hosting (starts at $10/month) as it distributes your website across multiple servers. Offers scalability for growing businesses.
- **Dedicated Hosting**: Most expensive option (starts at $80/month) but gives you complete control over a server and its resources. Suitable for high-traffic websites with specific needs.
- **WordPress Hosting**: Streamlined hosting for WordPress websites (starts at $3.95/month) often includes features like one-click installation.
- **VPS Hosting**: Offers dedicated resources on a shared server, providing more control than shared hosting but less than a dedicated server (starts at $18/month).
### Beyond Hosting Costs:

1,883,224 | Generating replies with prompt chaining using Gemini API and NestJS | Introduction In this blog post, I demonstrated generating replies with prompt chaining.... | 27,661 | 2024-06-10T12:41:04 | https://www.blueskyconnie.com/generate-replies-with-prompt-chaining-using-gemini-api/ | generativeai, nestjs, gemini, tutorial | ##Introduction
In this blog post, I demonstrated generating replies with prompt chaining. Buyers can provide ratings and comments on sales transactions on auction sites like eBay. When the feedback is negative, the seller has to respond promptly to resolve the dispute. This demo saves time by generating replies in the same language as the buyer according to the tone (positive, neutral, or negative) and topics. Previous prompts obtain answers from the Gemini models and become a new prompt's parameters. Similarly, the model receives the new prompt to generate the final reply to keep customers happy.
###Generate Gemini API Key
Go to https://aistudio.google.com/app/apikey to generate an API key for a new or an existing Google Cloud project.
###Create a new NestJS Project
```bash
nest new nestjs-customer-feedback
```
###Install dependencies
```bash
npm i --save-exact @nestjs/swagger @nestjs/throttler dotenv compression helmet @google/generative-ai class-validator class-transformer
```
###Generate a Feedback Module
```bash
nest g mo advisoryFeedback
nest g co advisoryFeedback/presenters/http/advisoryFeedback --flat
nest g s advisoryFeedback/application/advisoryFeedback --flat
nest g s advisoryFeedback/application/advisoryFeedbackPromptChainingService --flat
```
Create an `AdvisoryFeedbackModule` module, a controller, a service for the API, and another service to build chained prompts.
###Define Gemini environment variables
```
// .env.example
PORT=3000
GOOGLE_GEMINI_API_KEY=<google gemini api key>
GOOGLE_GEMINI_MODEL=gemini-1.5-pro-latest
```
Copy `.env.example` to `.env`, and replace `GOOGLE_GEMINI_API_KEY` and `GOOGLE_GEMINI_MODEL` with the actual API Key and the Gemini model, respectively.
- PORT - port number of the NestJS application
- GOOGLE_GEMINI_API_KEY - API Key of Gemini
- GOOGLE_GEMINI_MODEL - Google model and I used Gemini 1.5 Pro in this demo
Add `.env` to the `.gitignore` file to prevent accidentally committing the Gemini API Key to the GitHub repo.
###Add configuration files
The project has 3 configuration files. `validate.config.ts` validates the payload is valid before any request can route to the controller to execute .
```typescript
// validate.config.ts
import { ValidationPipe } from '@nestjs/common';
export const validateConfig = new ValidationPipe({
whitelist: true,
stopAtFirstError: true,
forbidUnknownValues: false,
});
```
`env.config.ts` extracts the environment variables from process.env and stores the values in the env object.
```typescript
// env.config.ts
import dotenv from 'dotenv';
dotenv.config();
export const env = {
PORT: parseInt(process.env.PORT || '3000'),
GEMINI: {
API_KEY: process.env.GOOGLE_GEMINI_API_KEY || '',
MODEL_NAME: process.env.GOOGLE_GEMINI_MODEL || 'gemini-pro',
},
};
```
`throttler.config.ts` defines the rate limit of the Translation API
```typescript
// throttler.config.ts
import { ThrottlerModule } from '@nestjs/throttler';
export const throttlerConfig = ThrottlerModule.forRoot([
{
ttl: 60000,
limit: 10,
},
]);
```
Each route allows ten requests in 60,000 milliseconds or 1 minute.
###Bootstrap the application
```typescript
// bootstrap.ts
export class Bootstrap {
private app: NestExpressApplication;
async initApp() {
this.app = await NestFactory.create(AppModule);
}
enableCors() {
this.app.enableCors();
}
setupMiddleware() {
this.app.use(express.json({ limit: '1000kb' }));
this.app.use(express.urlencoded({ extended: false }));
this.app.use(compression());
this.app.use(helmet());
}
setupGlobalPipe() {
this.app.useGlobalPipes(validateConfig);
}
async startApp() {
await this.app.listen(env.PORT);
}
setupSwagger() {
const config = new DocumentBuilder()
.setTitle('ESG Advisory Feedback with Prompt Chaining ')
.setDescription('Integrate with Gemini to improve ESG advisory feebacking by prompt chaining')
.setVersion('1.0')
.addTag('Gemini API, Gemini 1.5 Pro Model, Prompt Chaining')
.build();
const document = SwaggerModule.createDocument(this.app, config);
SwaggerModule.setup('api', this.app, document);
}
}
```
Added a Bootstrap class to set up Swagger, middleware, global validation, CORS, and finally, application start.
```typescript
// main.ts
import { env } from '~configs/env.config';
import { Bootstrap } from '~core/bootstrap';
async function bootstrap() {
const bootstrap = new Bootstrap();
await bootstrap.initApp();
bootstrap.enableCors();
bootstrap.setupMiddleware();
bootstrap.setupGlobalPipe();
bootstrap.setupSwagger();
await bootstrap.startApp();
}
bootstrap()
.then(() => console.log(`The application starts successfully at port ${env.PORT}`))
.catch((error) => console.error(error));
```
The bootstrap function enabled CORS, registered middleware to the application, set up Swagger documentation, and validated payloads using a global pipe.
I have laid down the groundwork, and the next step is to add an endpoint to receive a payload for generating replies with prompt chaining.
###Define Feedback DTO
```typescript
// feedback.dto.ts
import { IsNotEmpty, IsString } from 'class-validator';
export class FeedbackDto {
@IsString()
@IsNotEmpty()
prompt: string;
}
```
`FeedbackDto` accepts a prompt, which is customer feedback.
###Construct Gemini Models
```typescript
// gemini.config.ts
import { GenerationConfig, HarmBlockThreshold, HarmCategory, SafetySetting } from '@google/generative-ai';
export const SAFETY_SETTINGS: SafetySetting[] = [
{
category: HarmCategory.HARM_CATEGORY_DANGEROUS_CONTENT,
threshold: HarmBlockThreshold.BLOCK_MEDIUM_AND_ABOVE,
},
{
category: HarmCategory.HARM_CATEGORY_HARASSMENT,
threshold: HarmBlockThreshold.BLOCK_MEDIUM_AND_ABOVE,
},
{
category: HarmCategory.HARM_CATEGORY_HATE_SPEECH,
threshold: HarmBlockThreshold.BLOCK_MEDIUM_AND_ABOVE,
},
{
category: HarmCategory.HARM_CATEGORY_SEXUALLY_EXPLICIT,
threshold: HarmBlockThreshold.BLOCK_MEDIUM_AND_ABOVE,
},
];
export const GENERATION_CONFIG: GenerationConfig = {
temperature: 0.5,
topK: 10,
topP: 0.5,
maxOutputTokens: 2048,
};
```
```typescript
// gemini.constant.ts
export const GEMINI_SENTIMENT_ANALYSIS_MODEL = 'GEMINI_SENTIMENT_ANALYSIS_MODEL';
export const GEMINI_REPLY_MODEL = 'GEMINI_REPLY_MODEL';
export const GEMINI_FIND_LANGUAGE_MODEL = 'GEMINI_FIND_LANGUAGE_MODEL';
```
```typescript
// mode.factory.ts
import { GoogleGenerativeAI } from '@google/generative-ai';
import { env } from '~configs/env.config';
import { GENERATION_CONFIG, SAFETY_SETTINGS } from '../configs/genimi.config';
export function modelFactory(systemInstruction: string, toJson = false) {
const genAI = new GoogleGenerativeAI(env.GEMINI.API_KEY);
const generationConfig = toJson ? { ...GENERATION_CONFIG, responseMimeType: 'application/json' } : GENERATION_CONFIG;
return genAI.getGenerativeModel({
model: env.GEMINI.MODEL_NAME,
systemInstruction,
generationConfig,
safetySettings: SAFETY_SETTINGS,
});
}
```
```typescript
// gemini-find-language.provider.ts
import { GenerativeModel } from '@google/generative-ai';
import { Provider } from '@nestjs/common';
import { GEMINI_FIND_LANGUAGE_MODEL } from '../constants/gemini.constant';
import { modelFactory } from './model-factory';
const FIND_LANGUAGE_SYSTEM_INSTRUCTION = `You are a multilingual expert that can identify the language used in this piece of text. Give me the language name, and nothing else.
If the text is written in Chinese, please differentiate Traditional Chinese and Simplified Chinese.
`;
export const GeminiFindLanguageProvider: Provider<GenerativeModel> = {
provide: GEMINI_FIND_LANGUAGE_MODEL,
useFactory: () => modelFactory(FIND_LANGUAGE_SYSTEM_INSTRUCTION),
};
```
The Gemini 1.5 Pro model accepts system instruction, which gives the model context. `GeminiFindLanguageProvider` is a model that can detect written language. When the language is Chinese, it should distinguish between Traditional Chinese and Simplified Chinese.
```typescript
// sentiment-model.provider.ts
const SENTIMENT_ANALYSIS_SYSTEM_INSTRUCTION = `
You are a sentiment analysis assistant who can identify the sentiment and topic of feedback and return the JSON output { "sentiment": string, "topic": string }.
When the sentiment is positive, return 'POSITIVE', is neutral, return 'NEUTRAL', is negative, return 'NEGATIVE'.
`;
export const GeminiSentimentAnalysisProvider: Provider<GenerativeModel> = {
provide: GEMINI_SENTIMENT_ANALYSIS_MODEL,
useFactory: () => modelFactory(SENTIMENT_ANALYSIS_SYSTEM_INSTRUCTION, true),
};
```
`GeminiSentimentAnalysisProvider` is a model that can identify the sentiment and topics of the feedback, and return the result in JSON. The JSON schema of the result is `{ sentiment: string; topic: string }`.
```typescript
// advisory-feedback-model.provider.ts
const REPLY_SYSTEM_INSTRUCTION =
"You are a professional ESG advisor, please give a short reply to customer's response and in the same language.";
export const GeminiReplyProvider: Provider<GenerativeModel> = {
provide: GEMINI_REPLY_MODEL,
useFactory: () => modelFactory(REPLY_SYSTEM_INSTRUCTION),
};
```
`GeminiReplyProvider` is a model that writes a short reply in the same language as the feedback.
###Implement Reply Service
```typescript
// sentiment-analysis.type.ts
export type SentimentAnalysis = {
sentiment: 'POSITIVE' | 'NEUTRAL' | 'NEGATIVE';
topic: string;
};
```
```typescript
// advisory-feedback-prompt-chaining.service.ts
// Omit the import statements
@Injectable()
export class AdvisoryFeedbackPromptChainingService {
private readonly logger = new Logger(AdvisoryFeedbackPromptChainingService.name);
constructor(
@Inject(GEMINI_SENTIMENT_ANALYSIS_MODEL) private analysisModel: GenerativeModel,
@Inject(GEMINI_REPLY_MODEL) private replyModel: GenerativeModel,
@Inject(GEMINI_FIND_LANGUAGE_MODEL) private findLanguageModel: GenerativeModel,
) {}
async generateReply(prompt: string): Promise<string> {
try {
const [analysis, language] = await Promise.all([this.analyseSentinment(prompt), this.findLanguage(prompt)]);
const { sentiment, topic } = analysis;
const chainedPrompt = `
The customer wrote a ${sentiment} feedback about ${topic} in ${language}. Provided feedback: ${prompt}.
Feedback:
`;
this.logger.log(chainedPrompt);
const result = await this.replyModel.generateContent(chainedPrompt);
const response = await result.response;
const text = response.text();
this.logger.log(text);
return text;
} catch (ex) {
console.error(ex);
throw ex;
}
}
private async analyseSentinment(prompt: string): Promise<SentimentAnalysis> {
try {
const result = await this.analysisModel.generateContent(prompt);
const response = await result.response;
return JSON.parse(response.text()) as SentimentAnalysis;
} catch (ex) {
console.error(ex);
throw ex;
}
}
private async findLanguage(prompt: string): Promise<string> {
try {
const languageResult = await this.findLanguageModel.generateContent(prompt);
const languageResponse = await languageResult.response;
return languageResponse.text();
} catch (ex) {
console.error(ex);
throw ex;
}
}
}
```
`AdvisoryFeedbackPromptChainingService` injects three chat models in the constructor.
- findLanguageModel - A chat model for detecting the language of the feedback.
- analysisModel - A chat model declared for determining the sentiment (POSITIVE, NEUTRAL, NEGATIVE) and the topics of the feedback.
- replyModel - A chat model declared for generating replies with prompt chaining.
- findLanguage - a private method that uses the findLanguageModel to detect the language of the feedback.
- analyseSentinment - a private method that uses the analysisModel to determine the sentiment and the topics of the feedback.
- generateReply - this method uses the results of findLanguage and analyseSentinment to construct a chained prompt. Then, it uses the replyModel to generate replies in the same language based on sentiment and topics.
The process for generating replies with prompt chaining ended by producing the text output from `generateReply`. The method asked questions iteratively and wrote a clear prompt for the LLM to draft a reply that was polite and addressed the need of the customer.
```typescript
// advisory-feedback.service.ts
// Omit the import statements to save space
@Injectable()
export class AdvisoryFeedbackService {
constructor(private promptChainingService: AdvisoryFeedbackPromptChainingService) {}
generateReply(prompt: string): Promise<string> {
return this.promptChainingService.generateReply(prompt);
}
}
```
`AdvisoryFeedbackService` injects `AdvisoryFeedbackPromptChainingService` and derives chained prompts to ask chat models to generate a reply.
###Implement Advisory Feedback Controller
```typescript
// advisory-feedback.controller.ts
// Omit the import statements to save space
@Controller('esg-advisory-feedback')
export class AdvisoryFeedbackController {
constructor(private service: AdvisoryFeedbackService) {}
@Post()
generateReply(@Body() dto: FeedbackDto): Promise<string> {
return this.service.generateReply(dto.prompt);
}
}
```
The `AdvisoryFeedbackController` injects `AdvisoryFeedbackService` using Gemini API and Gemini 1.5 Pro model. The endpoint invokes the method to generate a reply from the prompt.
- /esg-advisory-feedback - generate a reply from a prompt
Module Registration
The `AdvisoryFeedbackModule` provides `AdvisoryFeedbackPromptChainingService`, `AdvisoryFeedbackService`, `GeminiSentimentAnalysisProvider`, `GeminiAdvisoryFeedbackProvider` and `GeminiFindLanguageProvider`. The module has one controller that is `AdvisoryFeedbackController`.
```typescript
// advisory-feedback.module.ts
// Omit the import statements due to brevity reason
@Module({
controllers: [AdvisoryFeedbackController],
providers: [
AdvisoryFeedbackPromptChainingService,
AdvisoryFeedbackService,
GeminiSentimentAnalysisProvider,
GeminiReplyProvider,,
GeminiFindLanguageProvider,
],
})
export class AdvisoryFeedbackModule {}
```
###Import AdvisoryFeedbackModule into AppModule.
```typescript
// app.module.ts
@Module({
imports: [throttlerConfig, AdvisoryFeedbackModule],
controllers: [AppController],
providers: [
{
provide: APP_GUARD,
useClass: ThrottlerGuard,
},
],
})
export class AppModule {}
```
###Test the endpoints
I can test the endpoints with cURL, Postman or Swagger documentation after launching the application.
```bash
npm run start:dev
```
The URL of the Swagger documentation is http://localhost:3000/api.
In cURL
```bash
curl --location 'http://localhost:3000/esg-advisory-feedback' \
--header 'Content-Type: application/json' \
--data '{
"prompt": "Looking ahead, the needs of our customers will increasingly be defined by sustainable choices. ESG reporting through diginex has brought us uniformity, transparency and direction. It provides us with a framework to be able to demonstrate to all stakeholders - customers, employees, and investors - what we are doing and to be open and transparent."
}'
```
###Dockerize the application
```
// .dockerignore
.git
.gitignore
node_modules/
dist/
Dockerfile
.dockerignore
npm-debug.log
```
Create a `.dockerignore` file for Docker to ignore some files and directories.
```
// Dockerfile
# Use an official Node.js runtime as the base image
FROM node:20-alpine
# Set the working directory in the container
WORKDIR /app
# Copy package.json and package-lock.json to the working directory
COPY package*.json ./
# Install the dependencies
RUN npm install
# Copy the rest of the application code to the working directory
COPY . .
# Expose a port (if your application listens on a specific port)
EXPOSE 3000
# Define the command to run your application
CMD [ "npm", "run", "start:dev"]
```
I added the Dockerfile that installs the dependencies, builds the NestJS application, and starts it at port 3000.
```yaml
// docker-compose.yaml
version: '3.8'
services:
backend:
build:
context: .
dockerfile: Dockerfile
environment:
- PORT=${PORT}
- GOOGLE_GEMINI_API_KEY=${GOOGLE_GEMINI_API_KEY}
- GOOGLE_GEMINI_MODEL=${GOOGLE_GEMINI_MODEL}
ports:
- "${PORT}:${PORT}"
networks:
- ai
restart: unless-stopped
networks:
ai:
```
I added the docker-compose.yaml in the current folder, which was responsible for creating the NestJS application container.
###Launch the Docker application
```bash
docker-compose up
```
Navigate to http://localhost:3000/api to read and execute the API.
This concludes my blog post about using Gemini API and Gemini 1.5 Pro model to tackle generating replies regardless the written languages. Generating replies with prompt chaining reduces the efforts that a writer needs to compose a polite reply to any customer. I only scratched the surface of the capability of Gemini API and Gemini 1.5 Pro model because Gemini 1.5 Pro model can not only understand text inputs but also multimedia such as images and audios. I hope you like the content and continue to follow my learning experience in Angular, NestJS, Generative AI, and other technologies.

1,883,230 | 5 Ways to Swap Two Variables Without Using a Third Variable in Javascript | Swapping variables is a common task in programming, and there are several ways to do it without using... | 0 | 2024-06-10T12:38:31 | https://dev.to/amitkumar13/5-ways-to-swap-two-variables-without-using-a-third-variable-in-javascript-1845 | javascript, swapnumber | Swapping variables is a common task in programming, and there are several ways to do it without using a third variable. In this post, we'll explore five different methods in JavaScript, each with a detailed explanation.
## 1. Addition and Subtraction
This method involves simple arithmetic operations:
```
a = a + b;
b = a - b;
a = a - b;
console.log('After Addition and Subtraction:');
console.log('a:', a); // 40
console.log('b:', b); // 20
```
**Explanation:**
`a = a + b;` combines the values of `a` and `b` and stores the result in `a`.
`b = a - b;` subtracts the new value of `b` (which is `a`) from `a` to get the original value of `a`.
`a = a - b;` subtracts the new value of `b` (original `a`) from `a` to get the original value of `b`.
## 2. Multiplication and Division
Another arithmetic method, but using multiplication and division. Note that this method assumes `a` and `b` are non-zero to avoid division by zero:
```
a = 20;
b = 40;
a = a * b;
b = a / b;
a = a / b;
console.log('After Multiplication and Division:');
console.log('a:', a); // 40
console.log('b:', b); // 20
```
**Explanation:**
`a = a * b;` multiplies the values of `a` and `b` and stores the result in `a`.
`b = a / b;` divides the new value of `a` by `b` to get the original value of `a`.
`a = a / b;` divides the new value of `a` by the new value of `b` to get the original value of `b`.
## 3. Using Bitwise XOR
Bitwise operations can also be used to swap variables:
```
a = 20;
b = 40;
a = a ^ b;
b = a ^ b;
a = a ^ b;
console.log('After Bitwise XOR:');
console.log('a:', a); // 40
console.log('b:', b); // 20
```
**Explanation:**
`a = a ^ b;` stores the result of the bitwise XOR of `a` and `b` in `a`.
`b = a ^ b;` stores the result of the bitwise XOR of the new `a` and `b` (which is the original `a`) in `b`.
`a = a ^ b;` stores the result of the bitwise XOR of the new `a` and `b` (which is the original `b`) in `a`.
## 4. Using Array Destructuring
A more modern and elegant approach in JavaScript uses array destructuring:
```
a = 20;
b = 40;
[a, b] = [b, a];
console.log('After Array Destructuring:');
console.log('a:', a); // 40
console.log('b:', b); // 20
```
**Explanation:**
`[a, b] = [b, a];` swaps the values of `a` and `b` using array destructuring assignment. This is a concise and readable way to swap variables in modern JavaScript.
## 5. Compound Assignment Swap (Single Line Swap)
This clever method uses `a` combination of arithmetic and assignment in a single line:
```
a = 20;
b = 40;
a = a + b - (b = a);
console.log('After Compound Assignment Swap:');
console.log('a:', a); // 40
console.log('b:', b); // 20
```
**Explanation:**
`a = a + b - (b = a);` may look complex but it follows a specific sequence of operations due to how JavaScript evaluates expressions. Here's what happens:
1. `(b = a)` assigns the value of `a` to `b`.
2. Then, `a + b - (b = a)` becomes `a + a - a`, which effectively swaps the values of `a` and `b`.
In summary, each of these methods achieves the same result of swapping variables `a` and `b` without using a third variable, showcasing different techniques in JavaScript. | amitkumar13 |

1,883,226 | BigCommerce Performance Optimization Tips | In today's lightning-fast digital world, website speed is no longer a luxury - it's a necessity.... | 0 | 2024-06-10T12:35:55 | https://dev.to/developermansi/bigcommerce-performance-optimization-tips-4j33 | bigommerce, performanceoptimization |
In today's lightning-fast digital world, website speed is no longer a luxury - it's a necessity. This is especially true for eCommerce stores built on platforms like BigCommerce. Every millisecond a page takes to load can mean the difference between a satisfied customer and an abandoned cart.
## 5 Tips for Performance Optimization
Optimizing your BigCommerce store for better performance can lead to faster page load times, improved user experience, and potentially higher conversion rates. Here are five practical tips to help enhance the performance of your BigCommerce store:
**Tame the Image Beast**: Images are a crucial part of any eCommerce store, but they can also be major culprits behind slow loading times. Resizing images to fit your website's layout and using the right file format (JPEG for photos, PNG for graphics) can significantly reduce their weight. Consider using a Content Delivery Network (CDN) to deliver these optimized images to your visitors from geographically dispersed servers, further reducing load times.
**Code Cleanup Crew**:Over time, your BigCommerce store's code can accumulate bloat from unused apps, plugins, and scripts. Regularly audit your store's codebase and remove anything that's no longer serving a purpose. This will streamline your website and make it load faster. BigCommerce also offers built-in tools like Stencil Optimizer to help with this process.
**Caching the Cavalry**: Caching involves storing frequently accessed data on your server, so it doesn't have to be retrieved from the database every time a visitor loads a page. This can dramatically improve page load times, especially for returning visitors. BigCommerce offers built-in caching functionalities, but you can also explore third-party caching solutions for even more control.
**App Appraisal**:Third-party apps can add great functionality to your BigCommerce store, but they can also slow things down if not chosen carefully. Before installing any app, research its reputation and impact on performance. Consider if there are built-in BigCommerce features that can achieve the same results without the performance hit.
**Mobile Marvel Makeover:**
With the ever-increasing dominance of mobile shopping, ensuring your BigCommerce store offers a seamless experience on smartphones and tablets is crucial. BigCommerce offers responsive design options, but you can further optimize the mobile experience by prioritizing mobile-essential content and using image optimization techniques specifically for mobile devices.
## Bonus Tip: Stay Updated:
BigCommerce is constantly rolling out updates and improvements. Keeping your store and apps updated ensures you benefit from the latest performance optimizations and security patches.
## BigCommerce Development Services: Your Partner in Speed
While these tips are a great starting point, optimizing your BigCommerce store for peak performance can involve complex tasks. This is where BigCommerce development services from a reputable agency can be invaluable. They can help you with:
**In-depth performance audits**: Identify bottlenecks and areas for improvement
**Custom theme development**:Create a lightweight and efficient theme tailored to your brand
**Integration expertise**: Ensure smooth integration of third-party apps without compromising speed
**Code optimization**: Clean up code and streamline processes for optimal performance
By following these tips and partnering with a [BigCommerce development service](https://www.wagento.com/solutions/bigcommerce/), you can turn your BigCommerce store into a speed demon, providing a smooth and enjoyable shopping experience for your customers, ultimately leading to more conversions and a thriving online business.

While you cannot guarantee the plan will be profitable, you can make it as realistic as possible with the expectation of going above break-even.
What should a business plan for a mobile app include?
## Why is mobile app research necessary?
**Improves standards of quality**
You might have a specific idea of the type of user experience that your app can offer.

Another method defined in the Object class that is often used is the equals method. Its signature is
`public boolean equals(Object o)`
This method tests whether two objects are equal. The syntax for invoking it is:
`object1.equals(object2);`
The default implementation of the **equals** method in the **Object** class is:
`public boolean equals(Object obj) {
return (this == obj);
}`
This implementation checks whether two reference variables point to the same object using the **==** operator. You should override this method in your custom class to test whether two distinct objects have the same content.
The **equals** method is overridden in many classes in the Java API, such as **java.lang.String** and **java.util.Date**, to compare whether the contents of two objects are equal. The **equals** method in the **String** class is inherited from the **Object** class and is overridden in the **String** class to test whether two strings are identical in content.
You can override the **equals** method in the **Circle** class to compare whether two circles are equal based on their radius as follows:
`public boolean equals(Object o) {
if (o instanceof Circle)
return radius == ((Circle)o).radius;
else
return this == o;
}`
The **==** comparison operator is used for comparing two primitive data type values or for determining whether two objects have the same references. The **equals** method is intended to test whether two objects have the same contents, provided that the method is overridden in the defining class of the objects. The **==** operator is stronger than the **equals** method, in that the **==** operator checks whether the two reference variables refer to the same object. Using the signature **equals(SomeClassName obj)** (e.g., **equals(Circle c))** to override the **equals** method in a subclass is a common mistake. You should use **equals(Object obj)**. | paulike |

A trademark can help distinguish your products or services from competitors, providing legal protection and enhancing brand value. Understanding the costs and process involved in trademarking a name is essential for businesses and individuals. This article provides a comprehensive guide on the costs and steps to trademark a name in California.
## Introduction
Trademarking a name involves registering it with the United States Patent and Trademark Office (USPTO) or the California Secretary of State. This process ensures that your business name, logo, or slogan is legally protected from unauthorized use. While the cost to trademark a name can vary, it generally includes application fees, legal fees, and other associated expenses.
## Importance of Trademarking a Name
Trademarking a name provides several benefits, including:
**Legal Protection:** Prevents others from using your brand name without permission.
**Brand Identity:** Establishes a unique brand identity and prevents consumer confusion.
**Business Value:** Enhances the value of your business by protecting its intellectual property.
**Nationwide Protection:** Offers protection across the United States when registered with the USPTO.
Types of Trademarks
Before diving into the costs, it’s important to understand the different types of trademarks:
Standard Character Mark: Protects the word itself without regard to font, style, or color.
Design Mark: Protects the specific visual appearance of a logo or design.
Composite Mark: Combines both word elements and design elements.
Federal vs. State Trademark Registration
Trademarks can be registered at both the federal and state levels. Federal registration with the USPTO offers nationwide protection, while state registration with the California Secretary of State offers protection within California.
## Federal Trademark Registration
Federal registration is advisable if you plan to operate or expand your business nationwide. The USPTO is responsible for federal trademark registration, and the process typically involves the following steps:
Search for Existing Trademarks: Conduct a trademark search to ensure your desired name is not already registered.
Application Submission: Submit an application to the USPTO, including the required fees.
Examination Process: The USPTO examines the application for compliance with legal requirements.
Publication and Opposition: The trademark is published in the Official Gazette, allowing others to oppose the registration.
Registration: If no oppositions are filed, the trademark is registered.
State Trademark Registration
State registration is suitable for businesses operating solely within California. The California Secretary of State handles state trademark registration, which involves:
Search for Existing Trademarks: Conduct a search to ensure your **[how much does it cost to trademark a name in california](https://trademarkregistrationagency.com/blog/how-much-does-it-cost-to-trademark-a-name-in-california/)** desired name is not already registered at the state level.
Application Submission: Submit an application to the California Secretary of State, including the required fees.
Examination and Registration: The state office examines the application and, if approved, registers the trademark.
Costs Involved in Trademarking a Name
The cost to trademark a name in California depends on several factors, including whether you choose to register at the federal or state level, the complexity of your trademark, and whether you hire legal assistance.
## Federal Trademark Registration Costs
**USPTO Filing Fees**
The USPTO charges different fees based on the type of application and the number of classes of goods or services:
TEAS Plus: $250 per class. Requires strict adherence to USPTO guidelines.
TEAS Standard: $350 per class. Offers more flexibility in the application process.
Legal Fees
While it is possible to file a trademark application without legal assistance, hiring an attorney can help navigate the complexities of the process. Legal fees for trademark registration typically range from $500 to $2,000, depending on the attorney’s experience and the complexity of the case.
## Additional Costs
**Other potential costs include:**
Trademark Search: Conducting a comprehensive trademark search to identify potential conflicts can cost between $300 and $500.
Office Action Responses: If the USPTO issues an Office Action requiring additional information or clarification, legal fees for responding can range from $200 to $1,000.
Trademark Monitoring: Services to monitor and protect your trademark from infringement can cost around $100 to $500 annually.
## State Trademark Registration Costs
Filing Fees
The California Secretary of State charges a fee for trademark registration:
State Filing Fee: $70 per class.
Legal Fees
Legal fees for state trademark registration are generally lower than federal registration and can range from $300 to $1,000.
Additional Costs
Other potential costs include:
**Trademark Search:** A state-level trademark search can cost between $100 and $300.
**Office Action Responses:** Legal fees for responding to state Office Actions can range from $100 to $500.
## The Trademark Registration Process
**Step-by-Step Guide for Federal Registration**
**Conduct a Trademark Search**
Utilize the USPTO’s Trademark Electronic Search System (TESS) to search for existing trademarks.
Consider hiring a professional service for a comprehensive search.
**Prepare the Application**
Choose between TEAS Plus and TEAS Standard applications.
Gather necessary information, including a description of the goods/services and a specimen showing the trademark in use.
**Submit the Application**
File the application electronically via the USPTO’s Trademark Electronic Application System (TEAS).
Pay the appropriate filing fee.
**Examination Process**
The USPTO examines the application for compliance with legal requirements.
Respond to any Office Actions if issued.
**Publication in the Official Gazette**
The trademark is published, allowing for a 30-day opposition period.
If no oppositions are filed, the trademark proceeds to registration.
**Registration and Maintenance**
Upon approval, the trademark is registered.
File periodic maintenance documents to keep the trademark active.
## Step-by-Step Guide for State Registration
**Conduct a Trademark Search**
Use the California Secretary of State’s online database to search for existing trademarks.
Consider hiring a professional service for a comprehensive search.
**Prepare the Application**
Gather necessary information, including a description of the goods/services and a specimen showing the trademark in use.
Submit the Application
File the application with the California Secretary of State’s office.
Pay the filing fee.
**Examination Process**
The state office examines the application for compliance with legal requirements.
Respond to any Office Actions if issued.
**Registration and Maintenance
**
Upon approval, the trademark is registered.
File periodic maintenance documents to keep the trademark active.
## Tips for a Successful Trademark Application
Conduct Thorough Searches: Ensure no existing trademarks conflict with your desired name.
**Hire Professional Assistance:** Consider hiring an attorney to navigate the complexities of the application process.
**Be Detailed and Accurate:** Provide comprehensive and accurate information in your application.
**Monitor Your Trademark:** Regularly monitor for potential infringements and take action if necessary.
**Stay Compliant:** File necessary maintenance documents to keep your trademark active.
## Conclusion
Trademarking a name in California involves several steps and costs, but it is a worthwhile investment for protecting your brand. Whether you choose to register at the federal or state level, understanding the process and associated expenses can help you make informed decisions.

This blog post explores domain suspension, a situation where your website becomes inaccessible due to an issue with your domain name registration. It highlights the common reasons for suspension and how to restore your domain, emphasizing the importance of a reliable web hosting provider.
### Why Do Domains Get Suspended?
- **Non-payment of renewal fees**: The most common reason. Missing a renewal can lead to traffic loss, revenue loss, and even domain expiration, making it vulnerable to acquisition by others.
- **Terms of service violation**: Hosting providers suspend domains for illegal activities like malware distribution or spamming. This can damage your reputation and online visibility.
- **Incomplete or inaccurate WHOIS data**: Outdated contact information in the WHOIS database (which stores domain ownership details) can lead to suspension due to difficulty reaching you or non-compliance with regulations.
- **Trademark infringement**: Choosing a domain name that infringes on a trademark can result in suspension and legal action.
### Regaining Control of Your Suspended Domain
- **Identify the cause**: Contact your domain registrar or hosting provider to determine why your domain is suspended. Knowing the reason is crucial for taking the next steps.
- **Address the issue promptly**: Whether it’s payment, a terms of service violation, or inaccurate WHOIS information, resolve the issue quickly to minimize downtime and expedite restoration.
- **Update WHOIS information**: Ensure your contact details in the WHOIS database are accurate and up-to-date.
- **Solve terms of service violations**: Remove any prohibited content, cease illegal activities, or resolve trademark disputes.
- **Improve security measures**: Strengthen passwords, update software and plugins, implement firewalls, and monitor activity for suspicious behavior to prevent future security breaches.
**Also Read** : [What is Web Hosting? Understand Its Types and Key Details](https://www.wewp.io/what-is-web-hosting-its-types/)
### How Can a Reliable Web Hosting Provider Help?
- **Reminders and auto-renewal**: Reputable providers send renewal reminders and offer auto-renewal options to prevent domain expiration.
- **Monitoring and secure infrastructure**: They employ robust security measures and infrastructure to safeguard your website, minimizing the risk of suspension due to security breaches.
- **Compliance with Terms of Service**: Reliable providers adhere to terms of service, helping you avoid violations that could lead to suspension.
- **Legal guidance and support**: Some providers offer legal support to assist with resolving trademark disputes and other legal issues that may cause suspension.
### Conclusion
Domain suspension can disrupt your online business, but by following these steps and choosing a reliable web hosting provider, you can minimize the risk and restore your domain quickly. The blog post author, WeWP, emphasizes their secure WordPress hosting solutions that include domain management features and support to help you avoid these issues.

---
Visual Studio Code is a powerful code editor known for its extensibility. Users can install various extensions to fit their needs, and if something isn't available, they can build their own extensions to enhance productivity. To do this, an extension author needs to be familiar with the VS Code API and the development workflow for creating extensions.
In this blog post, we will show you the framework we used to build an extension using a webview to display anything you like. We will guide you through the development of an extension, where you can modify the project to do specific tasks, and finally, we will show you how to officially publish an extension on the VS Code Marketplace.
_The published VS Code extension_
_Extension listed in VS Code_
## Preparation
The VS Code extension will be a TypeScript project, and for the webview, we will use Svelte as the frontend framework. We have prepared a VS Code extension development template so that you can clone this repository and get started right away:
GitHub repository: [https://github.com/codesphere-cloud/vscode-extension-template](https://github.com/codesphere-cloud/vscode-extension-template?ref=codesphere.ghost.io)
```bash
git clone https://github.com/codesphere-cloud/vscode-extension-template
cd vscode-extension-template
npm i
```
This will download the VS Code template and install all the dependencies you need for developing your extension.
That's it. You are ready to test and build your extension. First, we want to make sure that the tutorial extension works. When developing an extension, we want to test every change right away, and testing should be a smooth workflow.
We can open a debug VS Code window called `Extension-Development-Host` to test our extension. First, we run a command to compile our extension while working on it.
```
npm run watch
```
Tip: open a new Terminal with this Keyboard combination: Ctrl + Shift + .
This compiles our extension every time we are changing our project. now we open either `src/SidebarProvider.ts` or `src/extension.ts` file and push `F5` to open a new extension-developing-host. an this is the result:
_Activated tutorial extension in an extension-development-host_
The template extension we provide adds a view to the activity bar on the side with a webview a user can interact with. We kept this tutorial template as simple as possible, so you can follow along with this tutorial and get to know the project better while adding new features to it.
This tutorial focuses on creating a webview in the side panel of VS Code, but you can do much more than that. In the last section of this blog post, we will list a bunch of links to useful resources for further reference.
Now, we will build a GitHub Copilot-style chat interface together, but with a locally installed Llama.cpp.
## Project idea
The idea is to replicate the GitHub Co-Pilot chat interface on VS Code but with a locally self-hosted Llama.cpp instance. The use case for this would be if you are working on a project which data should not be exposed to other services. Such an approach of using AI would be data compliant.
We need to set up our local Llama.cpp instance and use the server example of this repository to host our own OpenAI compatible chat completion, so we have a nice to use API. Now, we guide you through the process of setting up your locally installed Llama.cpp instance.
Firstly, you need to clone the GitHub repository of llama.cpp and build the project with `make` . Make sure that you are in the root directory of the extension:
```
git clone https://github.com/ggerganov/llama.cpp
cd llama.cpp/
make
```
Depending on your local resources this command might take while. After completion we can continue to set up the OpenAI compatible server:
```bash
cd examples/server
make server
```
Like before this might take a while. After building the server we need to download our model we want to use. The important thing is to use models in the .gguf format. You can browse avalable models on HuggingFace: [https://huggingface.co/models?library=gguf&sort=trending](https://huggingface.co/models?library=gguf&sort=trending&ref=codesphere.ghost.io)
We chose the qwen2-7b-instruct-q8\_0.gguf model: [https://huggingface.co/Qwen/Qwen2-7B-Instruct-GGUF/tree/main](https://huggingface.co/Qwen/Qwen2-7B-Instruct-GGUF/tree/main?ref=codesphere.ghost.io)
It is 8 GB and to download it takes a while. You can download it to your models/ directory in your root:
```
cd models/
wget https://huggingface.co/Qwen/Qwen2-7B-Instruct-GGUF/resolve/main/qwen2-7b-instruct-q8_0.gguf?download=true
```
Simply replace this link with the link to the model you want to use. Now, you need to wait until this model is downloaded.
When downloading is finished you can use this model right away. Execute this command in the root directory of llama.cpp:
```
chmod a+x ./server
./server -m models/qwen2-7b-instruct-q8_0.gguf -c 2048
```
And again, if you chose an other model replace the path to the model to the right file.
You can now use the `Llama.cpp` interface on `localhost:8080`
_Llama.cpp server on localhost_
You can for sure optimize the performance of the model running now on your localhost, but lets stick with this for this tutorial because we want to build a VS Code extension.
Since we are using the API we wont need that UI. Here is a documentation about the API: [https://github.com/ggerganov/llama.cpp/tree/master/examples/server#API-Endpoints](https://github.com/ggerganov/llama.cpp/tree/master/examples/server?ref=codesphere.ghost.io#API-Endpoints)
## Features to add
Inside our sidepanel extension we want to add these features:
- start your AI model out of VS Code
- place an input field for your prompts
- use the completion endpoint of our model to generate a response
- display the response to our webview
We want to keep this extension simple and if you want to you can take the challenge and improve it as you like! 🤗
### Creating a Button to Start and Stop Llama.cpp
Let's create buttons so that we don't have to type the command in the terminal every time we want to use our Llama instance. Additionally, it would be convenient to have a button to stop the model from running, as we don't want to manually find out the PID in order to kill the process.
The idea is to add icons to the top-right corner. Perhaps you're familiar with some extensions that have these small icons in the top-right corner (e.g., GitHub Co-Pilot).
_Icons in the right top corner_
To add these buttons, we need to modify our package.json file first. The `package.json` file in our project is an important file filled with various metadata about your extension. This file serves as one of the main entry points to your extension. Inside the `package.json`, there is a field called `menus`. We will add two additional icons to our existing icon by appending these objects to that array.
```
"menus": {
"view/title": [
{
"command": "tutorial.tutorial",
"when": "view == tutorial-sidebar",
"group": "navigation"
},
{
"command": "tutorial.start",
"when": "view == tutorial-sidebar && !tutorial.modelIsRunning",
"group": "navigation"
},
{
"command": "tutorial.stop",
"when": "view == tutorial-sidebar && tutorial.modelIsRunning",
"group": "navigation"
}
]
},
```
In the `when` attribute, you can specify conditions for when the icons should be displayed. We can control variables through the VS Code API. We want the start icon to be displayed when the model is not running, and when it is running, we want to display the stop button.
We aim to use small icons for these commands. There is a variety of internal icons available for use: [Icon Listing](https://code.visualstudio.com/api/references/icons-in-labels?ref=codesphere.ghost.io#icon-listing)
In our `package.json` file, there is a `commands` field where we can add such icons. You can simply copy this snippet and replace it with the existing one:
```
"commands": [
{
"command": "tutorial.tutorial",
"title": "tutorial",
"icon": "$(log-out)",
"category": "Tutorial command"
},
{
"command": "tutorial.start",
"title": "Start",
"icon": "$(play)",
"category": "Tutorial command"
},
{
"command": "tutorial.stop",
"title": "Stop",
"icon": "$(stop)",
"category": "Tutorial command"
}
]
```
Now we save with Ctrl + S and navigate to our Extension Development Host, then press Ctrl + R to refresh the window. You should now see the icons displayed in the top-right corner.
_Icons in the top corner_
Perhaps you noticed that the stop button is not displayed. This is because of the condition we provided in the `package.json`.
Now let's code the commands that are executed when clicking on these icons. We need to open the src/extension.ts file to register our commands with the extension. We register the commands in the activation function of this file. In our `package.json`, there is a field named `activationEvents` where we can specify when the activation function is executed.
```
"activationEvents": [
"onStartupFinished"
],
```
The activation event is set to `onStartupFinished`. This means the activation function is executed when VS Code is fully loaded. You can copy this code snippet and paste it into `extension.ts`:
```
context.subscriptions.push(
vscode.commands.registerCommand('tutorial.start', async () => {
vscode.commands.executeCommand('setContext', 'tutorial.modelIsRunning', true);
})
);
context.subscriptions.push(
vscode.commands.registerCommand('tutorial.stop', async () => {
vscode.commands.executeCommand('setContext', 'tutorial.modelIsRunning', false);
})
);
```
Now, when you reload the Extension Development Host with Ctrl + R, you can test these icons, and you will notice that after clicking, the icon changes. This is the result of using the condition. We can change the context for the modelIsRunning variable during the runtime of your extension.
Now, we actually want to add functionality to our buttons. We can do that by simply extending the `registerCommand()` code block with the logic we want to have.
We want to start our LLama.cpp instance when clicking `start` and `stop` it when clicking `stop`. We need to execute these bash commands. You can again simply copy and paste this code snippet into the code you already have:
a) start Llama.cpp on localhost:8080:
```
context.subscriptions.push(
vscode.commands.registerCommand('tutorial.start', async () => {
const extension = vscode.extensions.getExtension('Tutorial.tutorial')?.extensionPath;
// Your Llama.cpp folder has to be inside the extension folder
const serverPath = path.join(extension, 'llama.cpp', 'server');
const modelPath = path.join(extension, 'llama.cpp', 'models', 'qwen2-7b-instruct-q8_0.gguf');
const bashcommand = `${serverPath} -m ${modelPath} -c 2048`;
const test = 'echo hi';
exec (bashcommand, (error, stdout, stderr) => {
if (error) {
console.error(`exec error: ${error}`);
return;
}
if (stderr) {
console.error(`stderr: ${stderr}`);
return;
}
console.log(`stdout: ${stdout}`);
});
vscode.commands.executeCommand('setContext', 'tutorial.modelIsRunning', true);
})
);
```
Note: We will save the PID (process ID) of the process to our extension's globalStorage to ensure that we can kill this process with our extension's stop button. The globalStorage can be used for state management in our extension.
b) stop Llama.cpp server:
```
context.subscriptions.push(
vscode.commands.registerCommand('tutorial.stop', async () => {
const pid = context.globalState.get("codesphere.runningPID");
console.log(pid)
const bashcommand = `kill ${pid as number + 1}`;
const childProcess = exec(bashcommand, (error, stdout, stderr) => {
if (error) {
console.error(`exec error: ${error}`);
return;
}
if (stderr) {
console.error(`stderr: ${stderr}`);
return;
}
console.log(`stdout: ${stdout}`);
});
context.globalState.update("codesphere.runningPID", "");
vscode.commands.executeCommand('setContext', 'tutorial.modelIsRunning', false);
})
);
```
We loaded the PID from our `globalStorage` and used it to terminate the correct process. And there we have it! Now we can start and stop our local Llama.cpp model as needed.
Tip: We actually have a webview developer console inside the extension development host to debug our extension. You can open it as follows:
- `Ctrl + Shift + P`
- select `Developer: Open Webview Developer Tools`
_Developer Console inside VS Code_
### Place an input field to our webview
The user needs to place the prompt somewhere. Let's create the UI for that within our Svelte file. For that, we simply need HTML, CSS, and JavaScript for the functionality.
In our Svelte file, we have a `<script>` tag for JavaScript code and a `<style>` tag for CSS. In the rest of the file, you can place the HTML code. Let's keep it simple, and if you want, you can practice your UI/UX design by enhancing this code as you like.
Add the following two code snippets to `src/webviews/components`:
a) CSS
```
.prompt-container {
display: flex;
align-items: center;
padding: 10px;
width: 100%;
max-width: 600px;
margin: 0 auto;
position: fixed;
bottom: 0;
left: 0;
}
.prompt-input {
flex: 1;
padding: 10px;
border: none;
outline: none;
font-size: 16px;
}
.prompt-button {
display: flex;
justify-content: center;
align-items: center;
padding: 10px 20px;
font-size: 16px;
border: none;
cursor: pointer;
border-radius: 4px;
margin-left: 10px;
width: 50px;
height: 50px;
align-self: end;
}
```
b) HTML
```
<div class="prompt-container">
<textarea type="text" placeholder="Ask your model something about your code" wrap="hard" class="prompt-input"></textarea>
<button class="prompt-button">
<svg xmlns="http://www.w3.org/2000/svg" width="100px" height="100px" viewBox="0 0 16 16">
<path fill="currentColor" fill-rule="evenodd" d="m4.25 3l1.166-.624l8 5.333v1.248l-8 5.334l-1.166-.624zm1.5 1.401v7.864l5.898-3.932z" clip-rule="evenodd"/>
</svg>
</button>
</div>
```
And this is the result:
_Added input field_
As you can see, we didn't add a color to our button, but it's blue. That's because in our project, we have some standard VS Code styles imported. You can find the styles in the media directory of our project.
### Split the webview to two different sections
It's time to split up our webview since the HelloWorld template has nothing to do with our chat interface. We can have multiple webviews in our sidebar simultaneously, like an accordion, where you can open and close the different webviews as you like.

"views": {
"tutorial-sidebar-view": [
{
"type": "webview",
"id": "tutorial-sidebar",
"name": "Tutoial",

{
"type": "webview",
"id": "tutorial-chat",

"icon": "media/tutorial.svg",
"contextualTitle": "Chat"
}
]
},
```
With that simple trick we created a second webview window inside our sidebar:
_Second window in the sidebar_
The content in our new chat window is loading infinitely because we haven't registered content for that window in our extension. Let's change that by adding code in src/extension.ts:
```
const chatProvider = new ChatProvider(context.extensionUri, context);
context.subscriptions.push(
vscode.window.registerWebviewViewProvider(
"tutorial-chat",
chatProvider
)
);
```
Now, when you refresh the extension development host, you will see that the content is loaded into the second webview. The reason this works without adding extra files is that we provided the necessary files in the template. Here is a list of the files you need to add to register this new webview:
- `ChatProvider.ts` in `/src`
- `Chat.svelte` in `webviews/components`
- `chat.ts` in `webview/pages`
If you are about to create another webview and you are using our `SidebarProvider.ts` as a template for that, you need to change the compiled JavaScript and CSS files to the correct ones.
```
const styleResetUri = webview.asWebviewUri(
vscode.Uri.joinPath(this._extensionUri, "media", "reset.css")
);
const scriptUri = webview.asWebviewUri(
// change here
vscode.Uri.joinPath(this._extensionUri, "out", "compiled/chat.js")
);
const styleMainUri = webview.asWebviewUri(
// change here
vscode.Uri.joinPath(this._extensionUri, "out", "compiled/chat.css")
);
const styleVSCodeUri = webview.asWebviewUri(
vscode.Uri.joinPath(this._extensionUri, "media", "vscode.css")
);
```
### Add functionality to our chat-interface
Now we have our UI, but we need the logic for handling our prompts and displaying the response. In order to do that, we need to send our prompt to our model via the API and send the response to our webview so that we can display it. It follows the same pattern when implementing logic for our extension:
1. Send data from the webview to our extension via the postMessage method.
2. Handle the message within our extension's code (e.g., ChatProvider.ts) inside the switch-case block.
3. Send back data to our webview with the postMessage method.
First, we define a function to forward our prompt to the extension and add this prompt to our chat interface. You can replace the `someMessage()` function with the following code:
```
function someMessage() {
// Clear the textarea
document.getElementById('promptInput').value = '';
// add textblock to chat interface
const chat = document.createElement('div');
let randomId = generateRandomId();
chat.innerHTML = `<div style=" background-color: #00BCFF;
color: black;
padding: 10px;
margin: 10px;
border-radius: 10px;
display: inline-block;">${prompt}</div>`;
document.getElementById('chatContainer').appendChild(chat);
// Create response div
const responseDiv = document.createElement('div');
// styling
responseDiv.style = "background-color: #6F40D3; color: black; padding: 10px; margin: 10px; border-radius: 10px; display: inline-block;";
responseDiv.id = randomId;
document.getElementById('chatContainer').appendChild(responseDiv);
vscode.postMessage({
type: 'prompt',
value: {
prompt: prompt,
id: randomId
}
});
}
```
The `postMessage()` method will send a message to our extension, and the `type` property of the message body will serve as the identifier for which case in our switch-case code block will be executed within the `ChatProvider.ts`.
```
webviewView.webview.onDidReceiveMessage(async (data) => {
switch (data.type) {
case "prompt": {
if (!data.value) {
return;
}
let prompt = data.value.prompt;
let id = data.value.id;
const Test = async (prompt: string, id: any) => {
try {
let response = await fetch("http://127.0.0.1:8080/completion", {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify({
prompt,
n_predict: 30,
stream: true,
}),
});
if (!response.ok) {
throw new Error(`HTTP error! status: ${response.status}`);
}
if (!response.body) {
throw new Error('Response body is null');
}
const reader = response.body.getReader();
const decoder = new TextDecoder();
let result = '';
while (true) {
const { done, value } = await reader.read();
if (done) {
break;
}
result += decoder.decode(value, { stream: true });
const lines = result.split('\n');
for (const line of lines) {
if (line.startsWith('data:')) {
try {
const json = JSON.parse(line.substring(5).trim());
console.log(json.content);
let token = json.content;
this._view?.webview.postMessage({
type: "response",
value: token,
id: id
});
} catch (e) {
console.error('Error parsing JSON:', e);
}
}
}
result = lines[lines.length - 1];
}
this._view?.webview.postMessage({
type: "response",
value: "done",
id: id
});
} catch (error) {
console.error('Error:', error);
}
};
await Test(prompt, id);
break;
}
}
});
```
This will handle our request to our running LLM. We call it in stream mode, which means that every token is sent separately back. Every time we get a token, we send this token back to our extension via the `postMessage` method so that we can add it to our chat interface within the webview's code.
```
onMount(() => {
window.addEventListener('message', event => {
const message = event.data; // The JSON data our extension sent
console.log(`message received: ${JSON.stringify(message)}`);
switch (message.type) {
case 'response':
if (message.value === 'done') {
// Mark the end of the response
break;
}
let responseDiv = document.getElementById(message.id)
responseDiv.innerHTML += message.value;
break;
}
});
});
```
Now we can have a chat with our locally hosted LLM.
_VS Code extension LLM chat_
## Publish an extension
When we decide that our extension is ready to be published, we can do so using the vsce CLI tool for managing VS Code extensions.
Fist we need to install the vsce CLI:
```
npm install -g @vscode/vsce
```
Packaging your project to a .vsix file is the easiest way to share your extension. You need to run this command in the root directory of your project:
```
vsce pack
```
However, since it's not always trustworthy to share files directly, we might want to publish our extension in the official [VS Code Extension Marketplace](https://marketplace.visualstudio.com/vscode?ref=codesphere.ghost.io). Since Microsoft's official documentation for publishing extensions is clear, we will just reference their documentation here: [Publishing Extension](https://code.visualstudio.com/api/working-with-extensions/publishing-extension?ref=codesphere.ghost.io).
Once you've completed everything and your extension is accepted, it will be listed and available for other users to install.

## Conclusion
This tutorial serves as a comprehensive guide for creating a Visual Studio Code extension from scratch. We utilized the template provided to build an extension that interacts with a running Llama.cpp instance on `localhost:8080`. While this tutorial covers a lot, there are many more possibilities to explore when creating VS Code extensions, but covering all of them would be too much for one blog post.
If you're interested in building your own VS Code extension, you can join our Discord Server to connect with fellow software developers, Codesphere users, and the Codesphere team: [Discord Server](https://discord.gg/codesphere?ref=codesphere.ghost.io).
Furthermore, if you want to improve this tutorial extension, there are plenty of things you can do! It's a great project to practice your coding skills and your VS Code extension creation skills. Here are some ideas for improvement:
- **Persistent Chats** : Implement a feature to save chat histories or conversations between sessions.
- **Creating a HuggingFace LLM Browser as a Separate Webview to Download Models** : Develop a separate webview interface where users can browse and download models from HuggingFace.
- **Fine-Tune Prompt Settings or Create a UI for User Settings** : Allow users to fine-tune prompt settings or provide a user-friendly UI for configuring settings related to the extension.
- **Improve UI/UX** : Enhance the user interface and experience of the extension to make it more intuitive and visually appealing.
- **User-Friendly Installation of Llama.cpp** : Simplify the installation process of Llama.cpp for users, possibly by automating or providing clear instructions within the extension.
- **Improve Model Performance Depending on User's Hardware** : Implement optimizations to enhance the performance of the model, taking into account the hardware specifications of the user's machine.
- **Implement Error Handling** : Develop mechanisms to handle errors gracefully, providing meaningful error messages and guiding users on how to resolve issues when they occur.
- **Cross-Platform Compatibility** : Ensure that the extension functions smoothly on the Mac, Linux, and Windows operating systems. | simoncodephere |
1,883,207 | Casting Objects and the instanceof Operator | One object reference can be typecast into another object reference. This is called casting object. In... | 0 | 2024-06-10T12:15:39 | https://dev.to/paulike/casting-objects-and-the-instanceof-operator-2hgj | java, programming, learning, beginners | One object reference can be typecast into another object reference. This is called casting object. In the preceding section, the statement
`m(new Student());`
assigns the object **new Student()** to a parameter of the **Object** type. This statement is equivalent to
`Object o = new Student(); // Implicit casting
m(o);`
The statement **Object o = new Student()**, known as _implicit casting_, is legal because an instance of **Student** is an instance of **Object**.
Suppose you want to assign the object reference **o** to a variable of the **Student** type using the following statement:
`Student b = o;`
In this case a compile error would occur. Why does the statement **Object o = new Student()** work but **Student b = o** doesn’t? The reason is that a **Student** object is always an instance of **Object**, but an **Object** is not necessarily an instance of **Student**. Even though you can see that **o** is really a **Student** object, the compiler is not clever enough to know it. To tell the compiler that **o** is a **Student** object, use _explicit casting_. The syntax is similar to the one used for casting among primitive data types. Enclose the target object type in parentheses and place it before the object to be cast, as follows:
Student b = (Student)o; // Explicit casting
It is always possible to cast an instance of a subclass to a variable of a superclass (known as _upcasting_), because an instance of a subclass is _always_ an instance of its superclass. When casting an instance of a superclass to a variable of its subclass (known as _downcasting_), explicit casting must be used to confirm your intention to the compiler with the **(SubclassName)** cast notation. For the casting to be successful, you must make sure that the object to be cast is an instance of the subclass. If the superclass object is not an instance of the subclass, a runtime **ClassCastException** occurs. For example, if an object is not an instance of **Student**, it cannot be cast into a variable of **Student**. It is a good practice, therefore, to ensure that the object is an instance of another object before attempting a casting. This can be accomplished by using the **instanceof** operator. Consider the following code:
`Object myObject = new Circle();
... // Some lines of code
/** Perform casting if myObject is an instance of Circle */
if (myObject instanceof Circle) {
System.out.println("The circle diameter is " +
((Circle)myObject).getDiameter());
...
}`
You may be wondering why casting is necessary. The variable **myObject** is declared **Object**. The _declared type_ decides which method to match at compile time. Using **myObject.getDiameter()** would cause a compile error, because the **Object** class does not have the **getDiameter** method. The compiler cannot find a match for **myObject.getDiameter()**. Therefore, it is necessary to cast **myObject** into the **Circle** type to tell the compiler that **myObject** is also an instance of **Circle**.
Why not define **myObject** as a **Circle** type in the first place? To enable generic programming, it is a good practice to define a variable with a supertype, which can accept an object of any subtype. **instanceof** is a Java keyword. Every letter in a Java keyword is in lowercase.
To help understand casting, you may also consider the analogy of fruit, apple, and orange, with the **Fruit** class as the superclass for **Apple** and **Orange**. An apple is a fruit, so you can always safely assign an instance of **Apple** to a variable for **Fruit**. However, a fruit is not necessarily an apple, so you have to use explicit casting to assign an instance of **Fruit** to a variable of **Apple**.
The program below demonstrates polymorphism and casting. The program creates two objects (lines 7–8), a circle and a rectangle, and invokes the **displayObject** method to display them (lines 11–12). The **displayObject** method displays the area and diameter if the object is a circle (line 17), and the area if the object is a rectangle (lines 21).
The **displayObject(Object object)** method is an example of generic programming. It can be invoked by passing any instance of **Object**.
The program uses implicit casting to assign a **Circle** object to **object1** and a **Rectangle** object to **object2** (lines 7–8), then invokes the **displayObject** method to display the information on these objects (lines 11–12).
In the **displayObject** method (lines 16–24), explicit casting is used to cast the object to **Circle** if the object is an instance of **Circle**, and the methods **getArea** and **getDiameter** are used to display the area and diameter of the circle.
Casting can be done only when the source object is an instance of the target class. The program uses the **instanceof** operator to ensure that the source object is an instance of the target class before performing a casting (line 17).
Explicit casting to **Circle** (lines 18, 19) and to **Rectangle** (line 22) is necessary because the **getArea** and **getDiameter** methods are not available in the **Object** class.
The object member access operator (**.**) precedes the casting operator. Use parentheses to ensure that casting is done before the . operator, as in
`((Circle)object).getArea();`
Casting a primitive type value is different from casting an object reference. Casting a primitive type value returns a new value. For example:
`int age = 45;
byte newAge = (byte)age; // A new value is assigned to newAge`
However, casting an object reference does not create a new object. For example:
`Object o = new Circle();
Circle c = (Circle)o; // No new object is created`
Now reference variables **o** and **c** point to the same object. | paulike |

## OUR TASK:
Write an incident report based on the pcap and the alerts.
The incident report should contain the following:
Executive Summary
Details (of the infected Windows host)
Indicators of Compromise (IOCs).
## Investigating the PCAP
Analyzing Network Traffic with Basic Filters:
```
(http.request || tls.handshake.type eq 1) && !(ssdp)
```
Upon inspection, a GET request to 185.244.41.29 on port 80 was detected, fetching a malicious Dynamic Link Library (DLL) file associated with Trickbot malware.
85.244.41.29 port 80 - 185.244.41.29 - GET /ooiwy.pdf
Post infection traffic initially consists of HTTPS/SSL/TLS traffic over TCP port 443, 447, or 449 and an IP address check by the infected Windows host. After infection, the compromised Windows host performs an IP address check. which we can see in this pcap: `port 443 - api.ipify.org - GET /`
```
(http.request || tls.handshake.type eq 1 || tcp.flags eq 1) && !ssdp
```
Shortly after the HTTP request for the Trickbot executable, several attempted TCP connections over port 443 to different IP addresses are observed, before a successful TCP connection to 46.99.175.149 and 182.253.210.130.
The HTTPS/SSL/TLS traffic to various IP addresses over TCP ports 447 and 449 has unusual certificate data. We can review the certificate issuer associated with these two hosts by filtering on:
```
tls.handshake.type == 11 && ip.addr==46.99.175.149 && ip.addr==182.253.210.130
```
Select the packet and go to the frame details section and expand the information.
TLS > TLSv1: Certificate > handshake protocol:certificate > certificates(__ bytes) > Certificates[truncated] > SignedCertificate > Issuer > rdnSequence
The state or province name (Some-State) and the organization name (Internet Widgits Pty Ltd) are not used for legitimate HTTPS/SSL/TLS traffic. This is an indicator of malicious traffic, and its not limited to Trickbot.
The Trickbot-infected Windows host will check its IP address using a number of different IP address checking sites. it needs to ascertain its geographical location or to determine if it's running in a virtual environment or a sandbox. This tactic allows the malware to blend in with normal network traffic, making it harder to detect and mitigate its activities. Various legitimate IP address checking services used by Trickbot include:
api.ip[.]sb
checkip.amazonaws[.]com
icanhazip[.]com
ident[.]me
ip.anysrc[.]net
ipecho[.]net
ipinfo[.]io
myexternalip[.]com
wtfismyip[.]com
Again, an IP address check by itself is not malicious. However, this type of activity combined with other network traffic can provide indicators of an infection. you may see above host in the packet.
A Trickbot infection can generates HTTP traffic. this traffic sends information from the infected host like system information and passwords from the browser cache and email clients. This information is sent from the infected host to C2 server used by Trickbot. apply the basic filter :
```
(http.request || tls.handshake.type eq 1) && !(ssdp)
```
you see a post request to host 103.148.41.195. view packet content and you see infomation like processes running on the infected host system, system information.
For a comprehensive understanding of Trickbot Malware, I recommend reading Brad Duncan's article on it: [Trickbot Malware](https://unit42.paloaltonetworks.com/wireshark-tutorial-examining-trickbot-infections/)

The build quality is truly impressive, boasting a sturdy full-metal construction. Featuring a 10mm SCP diaphragm, dual magnetic circuit, and dual cavity dynamic drivers, these IEMs promise an outstanding listening experience.
Let’s take a closer look at this review and take a closer look at its performance.
**SIMGOT EW200 Review 2024**
**Design**
Simgot EW200 catches your eye with its sleek and sophisticated design. I was surprised at how light it felt despite its full metal construction. The exterior surface has a nice raised circular area with the logo in the center and the company slogan surrounding it. It's minimalist but really luxurious.
EW200 has two holes. One is inside and the other is outside. They are there to prevent driver flex, which is a nice touch. Overall, I like the design of the EW200. It has the perfect combination of style and practicality that I appreciate.
Oh, and don't forget the nozzle. 5.6mm adds to overall comfort. And speaking of comfort, these babies are top-notch. Now as for the build quality, I'm honestly surprised. I mean, is there metal construction in this price range? It was definitely unexpected. I would give it a solid 10/10 for the build quality. I mean, come on, it's metal!
Now let's talk about cables. The Simgot EW200's stock cable is covered in a PVC sheath, which is quite impressive for the price of such an IEM. Visually, it is even more stunning with its gold and silver exterior.
One thing I really appreciate is the design of the 2-pin connector. It has a sunken shape. This means that there is a very thin plastic housing around the pins of the cable. This makes the cable versatile and allows it to be used with basically any IEM. It's a thoughtful touch that adds to the overall convenience and value of the EW200 package.
**Comfort**
Let's look at comfort. The Simgot EW200 really excels in this department. I put it to the test and found that I could wear it for hours on end without any discomfort! They fit well in my ears and the included SpinFit CP100 ear tips are fantastic. I personally prefer the medium size for excellent adhesion.
Overall, these IEMs are a pleasure to wear except for one minor thing. When cold, its metal structure may feel a bit cold for the first few seconds, which can be somewhat uncomfortable. But honestly, that's a minor quibble in an otherwise very comfortable experience.
**Sound**
As you can see from the frequency response graph on the box itself, the Simgot EW200 moves between the Harman Target 2016 and the Simgot-Classic Target. However, I noticed a difference between my FR and the FR provided by the manufacturer. In my case, the bass is closer to the midrange. And this is something I welcome. But to my ears, this is clearly a classier set in the upper mids than in the lows.
The Harman 2016 pattern seeks more clarity by stretching the midrange, limiting the control area of the first treble, and tilting the curve toward the sub-bass. A balanced profile with a clear tendency towards light without losing the presence of the deepest bass.
**Base**
The bass is dry and powerful, but tight and controlled, with very limited boominess, just enough to maintain a natural, realistic, and well-controlled performance. It's true that I prefer a bit more presence, but the EW200 has a bass that tends to be standard.
That said, it sounds as it should and is presented as a reference. It's not a weak bass, but it's nimble and fast for its price, has good color, is smooth and pleasant, and has a very dynamic action. It decays quickly and leaves little sediment in the sediment. It has no presence beyond the rest of the frequency range but has the executive power to demonstrate quality and presence when needed.
As much as we expect additional power... A bass of this quality and great lift would be welcome. However, control has its limits, and trade-offs are demonstrated across the range. Additionally, this is a clean bass with an emphasis on the sub-bass, gently descending towards the midrange, eliminating any resonance or emphasized mid-range aspects.
In this way, the EW200 demonstrates its wisdom, depth, know-how, agility in difficult conditions (reading dirty, unfiltered bass) and its ability to easily and clearly represent planes and follow complex bass lines.
In ultra-low frequency pure tone testing, the quality of the LFO's performance is noticeable. It is not easy for IEMS in this price range to produce natural and deep sound.
At lower limits, it sounds sensational, and at higher IEMS it performs without difficulty. As you increase the frequency, the notes become more audible, but without losing their naturalness, and are tuned for a very realistic tone, excellent performance for the price, and vivid and highly effective realism.
Perhaps, to put it mildly, the surface will be soft and smooth rather than rough or visceral. It's clean and doesn't tear, which limits the fun and informativeness of the texture. You can't have everything for $40, but it's great nonetheless.
**Gaming Experience**
When it comes to gaming, the Simgot EW200 really shines. The soundstage it provides is wide, creating a vivid sense of space that makes it easy to locate other players. Improved recognition of footsteps and the ability to hear accurate audio signals, such as shields breaking or exploding, or footsteps fading or approaching.
This improved spatial awareness is especially impressive in tactical shooters, where you can accurately identify enemy movements, gun grabs, drops, and reload directions.
The EW200's soundstage creates an immersive gaming atmosphere, while exceptional depth perception adds another layer to the experience. However, it's worth noting that the treble can feel a bit harsh at times, especially with certain guns, or in games when the champion's voice is too shrill or loud, which can lead to fatigue.
For example, AKM in The Finals can be particularly annoying and lead you to turn down your volume. Something I should add that I've noticed is that separation and layering can take a bit of a hit when things start to get very complicated around you.
In these situations, you may become a bit blurry and this may slightly affect your concentration. However, this is very situational and doesn't detract much from the overall gaming experience.
However, despite these shortcomings, I would like to recommend the EW200 for gaming without hesitation. A fantastic choice to bring your games to life and give you an edge in competitive play.
**Base**
It doesn't have the boomiest bass, but it's definitely solid and well-balanced. It's not too overwhelming, but just enough to give the music some depth.
What I really appreciate is how open and airy the bass feels. It doesn't feel punchy, which actually contributes to the spaciousness of the overall soundstage. It's as if the bass supports the music but doesn't overwhelm it. It's a nice touch that adds to the overall listening experience.
**Mid**
With the V-shaped tuning, I initially thought vocals and instruments would be overshadowed by the bass, but I was pleasantly surprised. Vocals come through clear and clean, and instruments have excellent separation and detail.
However, I found that it could get a bit muddy once things started to get very busy, with gunshots and footsteps being heard all around. It's not a deal breaker in any way, it's just something to be aware of. Nonetheless, the overall presentation of the midrange is still very enjoyable and offers a good balance of clarity and detail in most situations.
**Treble**
It's certainly nice and impressively detailed. However, I have to admit that I am a bit sensitive to treble, and this product can be a bit on the sharp side for me.
That said, the treble still delivers a realistic and natural tone. It has a sparkling, popping quality. You could almost say it's crunchy. There is a significant amount of energy in this range, which can really enhance certain tracks and in-game sounds.
I found myself needing to turn the volume down a bit, especially when using certain guns in the game. Raising it too high can make it a bit harsher. But it's by no means a deal breaker. All it takes is a little tweaking to find the sweet spot.
Overall, the EW200's treble adds nice detail and life to the sound but can be a bit overwhelming at times for those sensitive to higher frequencies.
**Things we like:**
Great sound for every penny paid, great value for money.
A very successful profile between Harman Target 2016 and
Excellent quality/price ratio.
Great construction level.
**Things we don't like:**
Bass presence is decent and fair, but for those looking for more punch, this probably won't be for you.
[Check Price](https://www.amazon.com/Linsoul-SIMGOT-EW200-Silver-Plated-Audiophiles/dp/B0C73X3P8B?&linkCode=ll1&tag=biem06-20&linkId=b461138f4224e94e905f3ac9e9045552&language=en_US&ref_=as_li_ss_tl)
**Conclusion**
Simgot showed what the EW100P can do at twice the price. Make no mistake. Its value is only $40, which undoubtedly allowed the brand to set a benchmark to beat in this narrow price range and fierce competition.
Rather than straying off the beaten track in search of alternative sounds, it's a cross between the Target Harman 2016 and Simgot's own Target. But in fact, the crossover offers characteristics of neutrality and clarity that are hard to find at this price.
At least not so far. I haven't used all of the IEMS under $50 and can't say the EW200 is the best. However, we can say that this is a clear and definite recommendation for those looking for a very high price-performance ratio, a sound that is clean, clear, detailed, skillful, dynamic, lively, and effective, in which all three ranges are well represented.
Especially the transition between the midrange and first treble, but without reaching the dangerous territory that such emphasis always entails. Smart execution, smart choices. But to all this, you have to add an exemplary level of construction, with a metal capsule that's as stylish and shiny as the sound.
It is true that it is a little heavy, but thanks to the excellent ergonomic design, it seems to disappear once it is in your ear. The cable fits well and comes with a cloth pouch for storage.

My journey started with the Piscine at 42 School—a four-week program where I got my feet wet with C programming. Next, I enrolled in Scrimba's Front End BootCamp to work more with front-end. Currently, I'm in the final stretch of a full-stack coding course, which is part of a 600-hour program.
One thing that's been puzzling me is why so many coding programs don't emphasize testing right from the beginning. I reached out to ChatGPT for insights—because what's better than a machine to answer me this—and the responses pointed towards complexity and the idea that it would be covered later. However, I'm convinced that testing early on is crucial for developing robust and reliable code.
Testing isn't just an afterthought; it's a fundamental aspect of coding that deserves attention from the start. Ignoring it early on can lead to bad habits and potentially costly mistakes down the line. Moreover, it's surprising to hear about companies that seemingly operate without thorough testing. It highlights the importance of prioritizing testing in our coding practices.
To the coding community, please, let’s talk more about testing. Sharing experiences, challenges, and successes can help us all become better programmers. Tests are all about improving the quality and reliability of our code.
In conclusion, let's acknowledge the significance of testing in our coding journeys. It's time we integrated it into our practices from the very beginning. Happy coding, and don't forget to keep tests in your heart and in your code. <3 | nicolasnardi404 |
1,883,203 | Mitigating DNS Hijacking: Strategies for Detection and Prevention | This blog post explores DNS hijacking, a cyberattack that redirects website traffic to malicious... | 0 | 2024-06-10T12:13:17 | https://dev.to/wewphosting/mitigating-dns-hijacking-strategies-for-detection-and-prevention-4de1 |
This blog post explores DNS hijacking, a cyberattack that redirects website traffic to malicious sites. It can steal sensitive information, install malware, and cause financial losses. Businesses are particularly vulnerable if their web hosting provider doesn’t prioritize security.
### Understanding DNS Hijacking
DNS, like a phone book, translates user-friendly domain names (e.g., example.com) into numerical IP addresses that computers understand. In DNS hijacking, attackers corrupt this process, rerouting traffic to fraudulent websites.
### Four Types of DNS Hijacking Attacks
- **Local DNS Hijacking**: Malware on a user’s computer alters DNS settings, unknowingly redirecting them to malicious sites.
- **DNS Router Hijacking**: Hackers exploit vulnerabilities in router firmware to change DNS settings, redirecting everyone using that network.
- **Man-in-the-Middle DNS Hijacking**: Attackers insert their IP address into DNS settings, directing users to a malware-laden website disguised as the intended one.
- **Rogue DNS Server Hijacking**: Hackers gain access to a DNS server and modify configurations, redirecting traffic from legitimate websites to malicious ones.
### Five Ways to Prevent DNS Hijacking
1. **Secure Your DNS Resolvers**: Firewalls protect legitimate DNS resolvers (which send queries to servers) from external access and prevent fake resolvers from redirecting traffic.
2. **Choose a Reliable Hosting Provider**: A reputable provider uses robust security measures like firewalls, DDoS mitigation, and DNSSEC (for verifying record authenticity) to safeguard your website.
3. **Train Staff on Security Best Practices**: Educate staff on cybersecurity practices like avoiding suspicious links, using strong passwords, and verifying email senders before clicking links.
4. **Limit Name Server Access**: Implement multi-factor authentication and strong firewalls to secure your name servers. Separate resolvers and authoritative name servers for added protection.
5. **Patch Known Vulnerabilities Promptly**: Regularly update software and firmware to eliminate vulnerabilities that hackers might exploit.

### Why Choosing a Reliable Hosting Provider Matters
Web hosting providers play a crucial role in preventing DNS hijacking. They offer:
- **Strong DNS Infrastructure**: Reliable providers invest in secure DNS infrastructure with advanced features like DNSSEC.
- **Up-to-date Security**: They regularly update systems with the latest security patches to minimize vulnerabilities.
- **DDoS Attack Mitigation**: Effective DDoS mitigation measures prevent attacks that disrupt website availability and can be used in conjunction with DNS hijacking attempts.
- **Detection and Response**: Experienced hosting companies use monitoring tools to detect suspicious activity and respond quickly to prevent further damage.
- **Security Authentication Practices**: Strong password policies and multi-factor authentication safeguard DNS management interfaces from unauthorized access.
### Conclusion
DNS hijacking is a serious threat, but by implementing security strategies and choosing a reliable hosting provider, you can significantly reduce the risk. WeWP, the blog post author, emphasizes their expertise in secure WordPress hosting solutions.

However, mocking this API can be tricky, especially when using Jest in ES6. In this post, I'll walk you through the issues I encountered and how I resolved them.
The first approach I tried was to overwrite the `clipboard` object directly. Unfortunately, this doesn't work in ES6 because the `clipboard` object has only a getter, making it read-only. Attempting to assign a new value to `clipboard` will result in an error.
```js
// This won't work
navigator.clipboard = {
writeText: jest.fn()
};
```
The solution is to use `jest.spyOn` to create a mock implementation of the `writeText` method. Here's how you can do that:
```js
jest.spyOn(navigator.clipboard, 'writeText');
```
However, when I tried this approach, I ran into another issue: a `DOMException` with the message "Type text/plain does not match the blob's type". After some digging, I realized that this error was occurring because the Jest environment doesn't implement the Clipboard API.
To work around this, I had to mock the `writeText` method using `spyOn` and make it return a resolved Promise:
```js
const writeTextMock = jest.spyOn(navigator.clipboard, 'writeText').mockResolvedValue();
```
With this approach, my tests could call `navigator.clipboard.writeText` without throwing any errors, and I could use the `writeTextMock` to assert that the method was called with the expected arguments.
```js
describe('MessagePane', () => {
it('should copy content to clipboard when button is clicked', async () => {
const messages = [
{ author: 'USER', content: 'Hello' },
{ author: 'BOT', content: 'Hi' },
];
const { user } = renderWithProviders(
<MessagePane messages={messages} />, {}
);
const writeTextMock = jest.spyOn(navigator.clipboard, 'writeText').mockResolvedValue();
const copyButtons = screen.getAllByRole('button');
await user.click(copyButtons[1]);
expect(writeTextMock).toHaveBeenCalledWith('Hi');
});
});
```
In summary, mocking the `navigator.clipboard.writeText` method in Jest requires a few steps:
1. Use `jest.spyOn` to create a mock implementation of the `writeText` method.
2. Make the mock implementation return a resolved Promise to avoid `DOMException` errors.
3. Use the mock instance to assert that the method was called as expected in your tests.
I hope this blog post helps you navigate the intricacies of mocking the Clipboard API in Jest. Happy testing! | andrewchaa |

My frequent mistake in Go is overusing pointers, like this unrealistic example below:
```Go
type BBox struct {
X1 float64
Y1 float64
X2 float64
Y2 float64
}
func ShowWidth(b *BBox) {
w := math.Abs(b.X2 - b.X1)
fmt.Println(w)
}
func main() {
b1 := BBox{X1: 10.1, Y1: 100.2, X2: 1024.4, Y2: 4096.188888}
b2 := BBox{X1: 10.1, Y1: 100.2, X2: 2024.4, Y2: 4096.188888}
b3 := BBox{X1: 10.1, Y1: 100.2, X2: 3024.4, Y2: 4096.188888}
ShowWidth(&b1)
ShowWidth(&b2)
ShowWidth(&b3)
}
```
I pass a pointer of BBox to _ShowWidth_, which according to [@meeusdylan's post](https://medium.com/@meeusdylan/when-to-use-pointers-in-go-44c15fe04eac), it slows down my program because the garbage collector has to determine if a _BBox_ must be in stack or heap.
In the alternative code below, I don't use pointer.
```Go
func ShowWidth(b BBox) {
w := math.Abs(b.X2 - b.X1)
fmt.Println(w)
}
func main() {
b1 := BBox{X1: 10.1, Y1: 100.2, X2: 1024.4, Y2: 4096.188888}
b2 := BBox{X1: 10.1, Y1: 100.2, X2: 2024.4, Y2: 4096.188888}
b3 := BBox{X1: 10.1, Y1: 100.2, X2: 3024.4, Y2: 4096.188888}
ShowWidth(b1)
ShowWidth(b2)
ShowWidth(b3)
}
```
I worried that my program will copy the entire _BBox_ every time ShowWidth is called. So, I checked the generated asssembly code. It looks like this:
```
ShowWidth(b1)
0x48098e f20f10059ab60300 MOVSD_XMM $f64.4024333333333333(SB), X0
0x480996 f20f100d9ab60300 MOVSD_XMM $f64.40590ccccccccccd(SB), X1
0x48099e f20f10159ab60300 MOVSD_XMM $f64.409001999999999a(SB), X2
0x4809a6 f20f101daab60300 MOVSD_XMM $f64.40b000305af6c69b(SB), X3
0x4809ae e82dffffff CALL main.ShowWidth(SB)
```
So, what I worried was true. MOVSD_XMM is for copying value from a member of a _BBox_ in memory to a register one-by-one. You may see MOVSD_XMM was called 4 times per each ShowWidth call.
I didn't measure which one is faster or slower. I've heard that Skymont support loads per cycle. And, I wish they meant loading float64 using MOVSD_XMM as well. So, copying entire _BBox_ is hopefully fast. And, at least, as far as I have been told, a BBox will definitely remain in stack without a need of checking by the GC.
Moreover, passing by value seems to comply to Go community better than pointer. So it will look familiar, and everyone will be happy to see passing by value.
My plan is avoiding pointer by default, and I will use it only when I have to. About performance, I think I may have to benchmark before using a pointer. Or if the speed is acceptable, I won't optimize. | veer66 |

Hey community,
I wanted to share a nifty tool that could save us a lot of time and cost when we're making edits to large texts. It's called **LLM Patcher**, and it's built with Next.js, the Vercel AI SDK, and OpenAI.
## The Problem: Time and Cost Inefficiencies
You know how painful it can be when we ask an LLM to make changes to a large document? It always sends back the entire modified text. For big files, this means:
1. **Time Drain**: We end up waiting for the whole text to stream back, which is super slow.
2. **Cost Spike**: It’s expensive because we’re processing and transferring more data than needed.
LLM Patcher is designed to tackle these issues head-on.
## Demo
## How LLM Patcher Works
Here’s a quick rundown of how it streamlines the process:
1. **Input and Query**: You feed it the text and a find-and-replace query.
2. **Text Segmentation**: It splits the text into lines and sentences.
3. **Identifier Prefixing**: Each segment gets a unique identifier (like `<l1s1>` for line 1, sentence 1).
4. **Find-and-Replace Execution**: The LLM processes each segment to apply the changes.
5. **Streaming Changes**: Instead of the whole text, it streams back just the changes in a diff format (e.g., `<r:l1s1> string to find || string to replace`).
## What LLM Patcher Is and Isn’t For
### What It’s Great For:
- Finding and replacing text in large documents.
- Editing and patching texts efficiently.
- Specific workflows like:
- Fixing typos or word replacements.
- Anonymizing texts by replacing names.
- Handling sensitive info by replacing it with placeholders.
- Enhancing texts with SEO keywords.
### What It’s Not Designed For:
- Generating text from scratch.
- Summarizing or translating text.
- Sentiment analysis.
- Acting as a chatbot.
- General-purpose LLM tasks.
## Getting Started
Setting it up locally is straightforward:
1. Clone the repo and navigate to the project directory.
2. Set up your environment variables as defined in `.env.example` for OpenAI integration.
3. Install dependencies and start the dev server:
```bash
pnpm install
pnpm dev
```
4. The app should now be live on [localhost:3000](http://localhost:3000/).
> **Heads Up**: Don’t commit your `.env` file – it contains sensitive info.
## Final Thoughts
LLM Patcher could be a real game-changer for a lot of workflows, especially when dealing with large text edits. It’s efficient, cost-effective, and tailored for find-and-replace operations. Check out the [LLM Patcher Repository](https://github.com/theluk/llm-patcher) to see it in action. You can also checkout out the live demo inside the repo!

1,883,200 | Mastering JavaScript Cross-Browser Testing🧪 | Cross-browser testing is crucial in web development to ensure that your application works seamlessly... | 0 | 2024-06-10T12:08:41 | https://dev.to/dharamgfx/mastering-javascript-cross-browser-testing-4meg | webdev, javascript, testing, programming |
Cross-browser testing is crucial in web development to ensure that your application works seamlessly across different browsers and devices. Let's dive into the various aspects of cross-browser testing, with simple titles and code examples to illustrate each point.
## Introduction to Cross-Browser Testing
Cross-browser testing ensures that your web application behaves consistently across different web browsers and their versions. It helps to identify and fix compatibility issues that might arise due to varying implementations of web standards by different browsers.
### Why is Cross-Browser Testing Important?
- **User Experience**: Consistent experience across all browsers improves user satisfaction.
- **Accessibility**: Ensures that everyone, regardless of the browser they use, can access and use your application.
- **Functionality**: Detects and resolves functionality issues caused by browser differences.
## Strategies for Carrying Out Testing
Effective cross-browser testing requires a strategic approach to cover all bases.
### 1. Define Your Target Browsers
Identify the browsers and versions most commonly used by your target audience.
```javascript
const targetBrowsers = ['Chrome', 'Firefox', 'Safari', 'Edge', 'IE11'];
```
### 2. Use Virtual Machines and Browser Emulators
Tools like BrowserStack and Sauce Labs allow testing on real browsers hosted on virtual machines.
### 3. Perform Regular Testing
Integrate cross-browser testing into your CI/CD pipeline to catch issues early.
## Handling Common HTML and CSS Problems
HTML and CSS inconsistencies can cause layout and styling issues across browsers.
### 1. Use a CSS Reset or Normalize.css
These libraries help to standardize the default styling across different browsers.
```css
/* Normalize.css example */
body {
margin: 0;
font-family: Arial, sans-serif;
}
```
### 2. Vendor Prefixes
Use tools like Autoprefixer to add necessary vendor prefixes.
```css
.example {
display: -webkit-flex; /* Safari */
display: flex;
}
```
### 3. Responsive Design
Ensure your site is responsive using media queries.
```css
@media (max-width: 600px) {
.container {
flex-direction: column;
}
}
```
## Handling Common JavaScript Problems
JavaScript behavior can differ across browsers, leading to unexpected issues.
### 1. Use Polyfills
Polyfills allow you to use modern JavaScript features in older browsers.
```html
<script src="https://cdn.polyfill.io/v3/polyfill.min.js"></script>
```
### 2. Avoid Browser-Specific Code
Write standard, clean JavaScript, and avoid relying on browser-specific features.
### 3. Test for Compatibility
Use tools like Babel to transpile modern JavaScript to be compatible with older browsers.
```javascript
// Using Babel to transpile ES6 to ES5
const greet = () => {
console.log('Hello, World!');
};
```
## Handling Common Accessibility Problems
Accessibility ensures that all users, including those with disabilities, can use your application.
### 1. Use Semantic HTML
Use proper HTML tags to improve accessibility.
```html
<button aria-label="Close">X</button>
```
### 2. ARIA Roles and Attributes
Use ARIA roles and attributes to enhance accessibility.
```html
<div role="dialog" aria-labelledby="dialogTitle" aria-describedby="dialogDescription">
<h1 id="dialogTitle">Dialog Title</h1>
<p id="dialogDescription">This is a dialog description.</p>
</div>
```
### 3. Test with Screen Readers
Use screen readers to test your application's accessibility.
## Implementing Feature Detection
Feature detection helps you determine whether a browser supports a particular feature.
### 1. Modernizr
Modernizr is a JavaScript library that detects HTML5 and CSS3 features in the user’s browser.
```html
<script src="https://cdnjs.cloudflare.com/ajax/libs/modernizr/2.8.3/modernizr.min.js"></script>
<script>
if (Modernizr.canvas) {
// Supported
} else {
// Fallback
}
</script>
```
## Introduction to Automated Testing
Automated testing reduces the effort required for cross-browser testing by running tests automatically.
### 1. Selenium WebDriver
Selenium is a popular tool for automating web application testing across different browsers.
```javascript
const { Builder, By, Key, until } = require('selenium-webdriver');
let driver = new Builder().forBrowser('firefox').build();
async function example() {
await driver.get('http://www.google.com');
await driver.findElement(By.name('q')).sendKeys('cross-browser testing', Key.RETURN);
await driver.wait(until.titleIs('cross-browser testing - Google Search'), 1000);
await driver.quit();
}
example();
```
### 2. Cypress
Cypress is a JavaScript-based end-to-end testing framework.
```javascript
describe('My First Test', () => {
it('Visits the Kitchen Sink', () => {
cy.visit('https://example.cypress.io')
cy.contains('type').click()
cy.url().should('include', '/commands/actions')
})
})
```
## Setting Up Your Own Test Automation Environment
Creating your own test automation environment can streamline the testing process.
### 1. Install Required Tools
Install Selenium, WebDriver, or Cypress using npm.
```bash
npm install selenium-webdriver
npm install cypress
```
### 2. Configure Test Scripts
Set up test scripts to run your automated tests.
```json
"scripts": {
"test": "cypress open"
}
```
### 3. Integrate with CI/CD
Integrate your test scripts with CI/CD tools like Jenkins or GitHub Actions to automate the testing process.
```yaml
name: Node.js CI
on: [push]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Use Node.js
uses: actions/setup-node@v1
with:
node-version: '14'
- run: npm install
- run: npm test
```
## Conclusion
Cross-browser testing is essential for delivering a consistent and accessible user experience. By following the strategies and tips outlined in this post, you can effectively handle common issues and implement automated testing to streamline your development process. Happy testing! | dharamgfx |

#Comparison Using a Real-World Example
When comparing AIOHTTP and Requests, it's crucial to evaluate several key factors: ease of use, scalability and concurrency, and suitability for large-scale applications. Let's examine these factors using the example of the [NSFW Image Classification API](https://api4.ai/apis/nsfw) developed by [API4AI](https://api4.ai/).
To perform image analysis using the NSFW API, the following steps are required:
- Set up the request data (the public URL of the image to be analyzed).
- Configure the request parameters (the algorithm’s strictness level).
- Execute a POST HTTP request to the designated endpoint.
- Extract and process the JSON data from the response.
Below are code examples demonstrating how to achieve these steps
using both AIOHTTP and Requests.
#AIOHTTP
```python
import asyncio
import sys
import aiohttp
API_URL = 'https://demo.api4ai.cloud/nsfw/v1/results'
async def main():
"""Entry point."""
image_url = sys.argv[1] if len(sys.argv) > 1 else 'https://storage.googleapis.com/api4ai-static/samples/nsfw-1.jpg'
async with aiohttp.ClientSession() as session:
# POST image as URL. Set some query parameters.
data = {'url': image_url}
params = {'strictness': 1.0}
async with session.post(API_URL, data=data, params=params) as response:
resp_json = await response.json()
resp_text = await response.text()
# Print raw response.
print(f'💬 Raw response:\n{resp_text}\n')
# Parse response and probabilities.
probs = resp_json['results'][0]['entities'][0]['classes']
print(f'💬 Probabilities:\n{probs}')
if __name__ == '__main__':
# Run async function in asyncio loop.
asyncio.run(main())
```
**Ease of Use: Readability and Maintainability of Code**
The AIOHTTP example showcases the structure of an asynchronous Python application. It necessitates an understanding of the async/await syntax, which can be a challenge for those unfamiliar with asynchronous programming.

For large-scale applications, particularly those requiring real-time data processing or managing numerous concurrent connections, AIOHTTP is often the superior choice. Its efficient handling of asynchronous operations makes it suitable for high-performance and scalable applications. However, the complexity of asynchronous code and the potential challenges in debugging and maintaining such a codebase should be considered.
#Requests
```python
import os
import sys
import requests
API_URL = 'https://demo.api4ai.cloud/nsfw/v1/results'
if __name__ == '__main__':
# Parse args.
image_url = sys.argv[1] if len(sys.argv) > 1 else 'https://storage.googleapis.com/api4ai-static/samples/nsfw-1.jpg'
# POST image as URL. Set some query parameters.
data = {'url': image_url}
params = {'strictness': 1.0}
response = requests.post(API_URL, data=data, params=params)
# Print raw response.
print(f'💬 Raw response:\n{response.text}\n')
# Parse response and probabilities.
probs = response.json()['results'][0]['entities'][0]['classes']
print(f'💬 Probabilities:\n{probs}')
```
**Ease of Use: Readability and Maintainability of Code**
The Requests example is straightforward and easy to read, making it one of the most accessible HTTP libraries for those new to Python or HTTP requests. Its synchronous nature means that the code executes line by line, which can be more intuitive for understanding and maintaining, especially in smaller projects or scripts.

The HTML class attribute is used to specify a class for an HTML element.
The class attribute is often used to point to a class name in a style sheet.
we have three `<div>` elements with a class attribute with the value of `"city"`. All of the three `<div>` elements will be styled equally according to the. city
we have two `<span>` elements with a class attribute with the value of "note".
Both `<span>` elements will be styled equally according to the. note style
```HTML
<!DOCTYPE html>
<html>
<head>
<style>
.city {
background-color: tomato;
color: white;
border: 2px solid black;
margin: 20px;
padding: 20px;
}
</style>
</head>
<body>
<div class="city">
<h2>London</h2>
<p>London is the capital of England.</p>
</div>
<div class="city">
<h2>Paris</h2>
<p>Paris is the capital of France.</p>
</div>
<div class="city">
<h2>Tokyo</h2>
<p>Tokyo is the capital of Japan.</p>
</div>
</body>
</html>
```
## **Syntax:**
write a period (.) character, followed by a class name. Then, define the CSS properties within curly braces {} to create a class.
```HTML
<!DOCTYPE html>
<html>
<head>
<title>
Example
</title>
<style>
. myClass
{
color: blue; font-size: 20px;
}
</style>
</head>
<body>
<p class="myClass">This is a paragraph with the class "myClass”. </p>
</body>
</html>
```
## **Multiple Classes**
HTML elements can belong to more than one class.
`<h2>` element belongs to both the city class and also to the main class
## **Example**
```HTML
<h2 class="city main">London</h2>
<h2 class="city">Paris</h2>
<h2 class="city">Tokyo</h2>
```
## **Different Elements Can Share Same Class**
Different HTML elements can point to the same class name.
both `<h2>` and `<p>` point to the `"city"` class and will share the same style:
## **Example**
```HTML
HTML
<h2 class="city">Paris</h2>
<p class="city">Paris is the capital of France</p>
```
## **Use of The class Attribute in JavaScript**
JavaScript can access elements with a specific class name with the `getElementsByClassName()` method
```HTML
<script>
function myFunction() {
var x = document.getElementsByClassName("city");
for (var i = 0; i < x.length; i++) {
x[i].style.display = "none";
}
}
</script>

<li v-for="todo in todos" :key="todo.id">{{ todo.text }}</li>
</ul>
</template>
<script>
export default {
data() {
return {
todos: []
}
}
}
</script>
```
### Adding a New Todo Form: Vue Events, Methods, and Models
**Handling Form Input:**
```vue
<template>
<div>
<input v-model="newTodo" @keyup.enter="addTodo">
<button @click="addTodo">Add Todo</button>
<ul>
<li v-for="todo in todos" :key="todo.id">{{ todo.text }}</li>
</ul>
</div>
</template>
<script>
export default {
data() {
return {
newTodo: '',
todos: []
}
},
methods: {
addTodo() {
this.todos.push({ id: Date.now(), text: this.newTodo });
this.newTodo = '';
}
}
}
</script>
```
### Styling Vue Components with CSS
**Adding Styles:**
```vue
<template>
<div class="todo-list">
<!-- rest of the component -->
</div>
</template>
<style>
.todo-list {
font-family: Arial, sans-serif;
}
</style>
```
### Using Vue Computed Properties
**Computed Properties:**
```vue
<script>
export default {
data() {
return {
todos: []
}
},
computed: {
todoCount() {
return this.todos.length;
}
}
}
</script>
```
### Vue Conditional Rendering: Editing Existing Todos
**Editing Todos:**
```vue
<template>
<ul>
<li v-for="todo in todos" :key="todo.id">
<input v-model="todo.text">
</li>
</ul>
</template>
<script>
export default {
data() {
return {
todos: []
}
}
}
</script>
```
### Vue Refs and Lifecycle Methods for Focus Management
**Using Refs:**
```vue
<template>
<input ref="todoInput">
</template>
<script>
export default {
mounted() {
this.$refs.todoInput.focus();
}
}
</script>
```

## Svelte
### Getting Started with Svelte
Svelte is a radical new approach to building user interfaces. Unlike traditional frameworks, Svelte shifts much of the work to compile time.
**Installation:**
```bash
npx degit sveltejs/template my-app
cd my-app
npm install
npm run dev
```
### Starting Our Svelte Todo List App
**Basic Structure:**
```svelte
<script>
let todos = [];
</script>
<main>
<h1>Todo List</h1>
</main>
```
### Dynamic Behavior in Svelte: Working with Variables and Props
**Adding Todos:**
```svelte
<script>
let todos = [];
let newTodo = '';
function addTodo() {
todos = [...todos, { id: Date.now(), text: newTodo }];
newTodo = '';
}
</script>
<input bind:value={newTodo} on:keyup.enter={addTodo}>
<button on:click={addTodo}>Add Todo</button>
<ul>
{#each todos as todo (todo.id)}
<li>{todo.text}</li>
{/each}
</ul>
```
### Componentizing Our Svelte App
**Creating Components:**
```svelte
<!-- TodoItem.svelte -->
<script>
export let todo;
</script>
<li>{todo.text}</li>
```
### Advanced Svelte: Reactivity, Lifecycle, Accessibility
**Reactive Statements:**
```svelte
<script>
let count = 0;
$: doubled = count * 2;
</script>
<p>Count: {count}</p>
<p>D
oubled: {doubled}</p>
<button on:click={() => count += 1}>Increment</button>
```
### Working with Svelte Stores
**Creating a Store:**
```javascript
// store.js
import { writable } from 'svelte/store';
export const todos = writable([]);
```
### TypeScript Support in Svelte
**Using TypeScript:**
```bash
npx degit sveltejs/template my-app
cd my-app
node scripts/setupTypeScript.js
npm install
npm run dev
```
### Deployment and Next Steps
**Deploying Svelte App:**
```bash
npm run build
```

## Angular
### Getting Started with Angular
Angular is a platform for building mobile and desktop web applications.
**Installation:**
```bash
npm install -g @angular/cli
ng new my-app
cd my-app
ng serve
```
### Beginning Our Angular Todo List App
**Basic Structure:**
```typescript
// app/app.component.ts
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
template: `
<h1>Todo List</h1>
`
})
export class AppComponent {}
```
### Styling Our Angular App
**Adding Styles:**
```css
/* src/styles.css */
body {
font-family: Arial, sans-serif;
}
```
### Creating an Item Component
**Item Component:**
```typescript
// app/todo-item/todo-item.component.ts
import { Component, Input } from '@angular/core';
@Component({
selector: 'app-todo-item',
template: `<li>{{ todo.text }}</li>`
})
export class TodoItemComponent {
@Input() todo;
}
```
### Filtering Our To-Do Items
**Filtering Todos:**
```typescript
// app/app.component.ts
export class AppComponent {
todos = [];
filter = '';
get filteredTodos() {
return this.todos.filter(todo => todo.text.includes(this.filter));
}
}
```

The JVM decides which... | 0 | 2024-06-10T11:55:13 | https://dev.to/paulike/dynamic-binding-5f8i | java, programming, learning, beginners | A method can be implemented in several classes along the inheritance chain. The JVM decides which method is invoked at runtime. A method can be defined in a superclass and overridden in its subclass. For example, the **toString()** method is defined in the **Object** class and overridden in **GeometricObject**.
Consider the following code:
`Object o = new GeometricObject();
System.out.println(o.toString());`
Which **toString()** method is invoked by **o**? To answer this question, we first introduce two terms: declared type and actual type. A variable must be declared a type. The type that declares a variable is called the variable’s _declared type_. Here **o**’s declared type is **Object**. A variable of a reference type can hold a **null** value or a reference to an instance of the declared type. The instance may be created using the constructor of the declared type or its subtype. The _actual type_ of the variable is the actual class for the object referenced by the variable. Here **o**’s actual type is **GeometricObject**, because **o** references an object created using **new GeometricObject()**. Which **toString()** method is invoked by **o** is determined by **o**’s actual type. This is known as _dynamic binding_.
Dynamic binding works as follows: Suppose an object **o** is an instance of classes **C1**, **C2**, . . . , **Cn-1**, and **Cn**, where **C1** is a subclass of **C2**, **C2** is a subclass of **C3**, . . . , and **Cn-1** is a subclass of **Cn**, as shown in Figure below. That is, **Cn** is the most general class, and **C1** is the most specific class. In Java, **Cn** is the **Object** class. If **o** invokes a method **p**, the JVM searches for the implementation of the method **p** in **C1**, **C2**, . . . , **Cn-1**, and **Cn**, in this order, until it is found. Once an implementation is found, the search stops and the first-found implementation is invoked.
The program below gives an example to demonstrate dynamic binding.
`Student
Student
Person
java.lang.Object@130c19b`
Method **m** (line 12) takes a parameter of the **Object** type. You can invoke **m** with any object (e.g., **new GraduateStudent()**, **new Student()**, **new Person()**, and **new Object()**) in lines 6–9).
When the method **m(Object x)** is executed, the argument **x**’s **toString** method is invoked. x may be an instance of **GraduateStudent**, **Student**, **Person**, or **Object**. The classes **GraduateStudent**, **Student**, **Person**, and **Object** have their own implementations of the **toString** method. Which implementation is used will be determined by x’s actual type at runtime. Invoking **m(new GraduateStudent())** (line 6) causes the **toString** method defined in the **Student** class to be invoked.
Invoking **m(new Student())** (line 7) causes the **toString** method defined in the **Student** class to be invoked; invoking **m(new Person())** (line 8) causes the **toString** method defined in the **Person** class to be invoked; and invoking **m(new Object())** (line 9) causes the **toString** method defined in the **Object** class to be invoked.
Matching a method signature and binding a method implementation are two separate issues. The _declared type_ of the reference variable decides which method to match at compile time. The compiler finds a matching method according to the parameter type, number of parameters, and order of the parameters at compile time. A method may be implemented in several classes along the inheritance chain. The JVM dynamically binds the implementation of the method at runtime, decided by the actual type of the variable. | paulike |

An online... | 0 | 2024-06-10T11:53:31 | https://dev.to/rajsharma/what-should-be-the-features-of-online-tarot-reading-website-5elf | webdev, features, website, tarot | In today's digital age, the mysterious art of tarot reading has found a new home online. An online tarot reading website can offer knowledge, guidance, and support to users from the comfort of their own homes. But what features make an online tarot reading website truly effective and user-friendly? Here are the essential features that such a website should include to ensure a high-quality experience for its users.
## User-Friendly Design
The website should have a clean, simple design that is easy to navigate. Users should easily find what they're looking for without getting lost in a maze of links.
Clear headings, menus, and categories help users quickly access different sections of the site.
## Accurate and Detailed Readings
Hire trustworthy and skilled tarot readers to guarantee accurate and keen readings. Reader profiles, highlighting their experience and skills, help to create trust.
Offer various types of readings (e.g., love, career, health, general guidance) to meet different user needs.
Provide detailed explanations of each card and its significance in the reading to enhance user understanding.
## Interactive Features
Provide choices for video readings and [**free astrology consultation online chat**](https://www.mpanchang.com/astrotalk/chat-with-astrologer/) to make the experience deeper and more interesting. With the use of this function, users can communicate with the reader directly, ask questions, and get fast answers.
Provide automated readings with pre-programmed algorithms for easy and quick access. Make sure these are made to offer useful knowledge even in the absence of a live reader.
## Customization and Personalization
Allow users to create profiles to save their reading history, choices, and personal notes. This feature helps users track their progress and review past readings.
Use the information from user profiles to offer personalized reading recommendations and understandings based on their individual situations.
## Educational Resources
Provide educational content such as articles, videos, and tutorials about tarot reading, the meanings of different cards, and how to analyze spreads. This assists users to learn and understand tarot on their own.
Include a dictionary of tarot terms and a complete FAQ section to answer common questions and clear the process for beginners.
## Secure and Private
Make sure that user interactions and readings are kept private. To protect user information, apply data encryption and secure communication routes.
The website's privacy policy should be made clear and should explain how user data is gathered, processed, and safeguarded. Users' trust is increased when these issues are transparent.
## Accessibility
Make sure the website is accessible so that customers can easily access readings and features on their tablets and smartphones.
To reach a worldwide audience, provide readings and content in several languages.
## Community Features
Create a community space where users can connect with other tarot followers, exchange stories, and ask questions. This encourages a feeling of unity and community.
Allow individuals to assess and comment on their interactions with various readers. Additionally, by using this feedback, we can keep our standards high and direct new customers to the best services.
## Easy Payment Options
Offer various payment options, including credit/debit cards, PayPal, and other online payment systems, to make transactions easy and convenient.
Clearly show the pricing for different services and reading packages. Transparency in pricing avoids confusion and builds trust.
## Customer Support
Provide excellent customer support through live chat, email, or phone. Quick and helpful responses to user inquiries and issues improve the overall experience.
Include a feature for users to submit feedback about their experience. Regularly review this feedback to improve the website and services.
## Conclusion
A good online tarot reading website has to include interactive elements, solid safety protocols, expert and accurate readings, and user-centric design. By adding these crucial components, you can develop a platform that increases community engagement and loyalty while also offering users useful knowledge. Moreover, a well-designed tarot reading website can provide the clarity and support someone needs on their path, regardless of whether they are looking for direction on love, job, or personal growth.
