1,921,952 | AWS Aurora Global Database | Aurora Global Database is an option supported on AWS Aurora MySQL and PostgreSQL engines enabling two... | 0 | 2024-07-13T05:26:29 | https://dev.to/dm8ry/aws-aurora-36na | aws, database, cloud, postgres | Aurora Global Database is an option supported on AWS Aurora MySQL and PostgreSQL engines enabling two primary use cases.
The first use case supports a disaster recovery solution that can handle a full regional failure with a low recovery point objective (RPO) and a low recovery time objective (RTO) while minimizing the performance impact on the protected database cluster.
The second major use case for Aurora Global Database is providing read-only copies of an Amazon Aurora cluster in up to five remote regions to serve users close to those regions. This provides users in remote regions with lower latency reads and some write capabilities than having to connect to the, further away, primary region.
Aurora was designed with high performance, reliability, and scalability in mind. It delivers high performance through innovative storage and replication mechanisms. It accesses data fast and supports high throughput. Aurora automatically scales data volume, ensuring performance and stability as the workload increases. Its built-in high availability mechanisms include automatic data backups and the ability to create replicas for read load balancing.
AWS Aurora is designed for intensive heavy-duty operations.
The AWS Aurora can be considered as a global database, that contains one primary and a few secondary clusters spread across multiple regions. The primary cluster of AWS Aurora is the cluster having one writer/reader DB instance with some extra readers. And secondary clusters are AWS Aurora clusters with reader DB instances.
AWS Aurora reader instances allow the offload of read-intensive workloads, to make the system more performant and scalable.
The AWS Aurora global database includes multiple AWS regions. It allows to have low-latency global reads and to enable disaster recovery in case of emergency across AWS regions.

One of the remarkable features of AWS Aurora is the distributed, fault-tolerant, auto-scaling storage decoupled from compute resources. The Amazon Aurora storage engine is a distributed SAN. It spans multiple availability zones (AZs) in a region. The storage is managed by AWS Aurora, and there is no need to provision its volume and I/O configuration.
The storage of AWS Aurora is distributed across regions, that’s why it takes milliseconds to get transactions executed on the primary cluster DB instance to be propagated to the secondary clusters.
The choice of AWS Aurora represents an advantage for critical enterprise-grade systems that require continuous availability. AWS Aurora replicates data across AZs in a region for high availability. It synchronously replicates data to six storage nodes connected to cluster volume across Availability Zones when it is written to the primary DB instance. In addition to avoiding I/O freezes and minimizing latency spikes during system backups, this approach offers data redundancy.
There are two main configurations of AWS Aurora: provisioned and serverless.
AWS Aurora provisioned option allows the creation of DB instances in the clusters of a specific type, for example, r7g.4xlarge. This is suitable when the workload has a constant predictable pattern. It creates the right balance between resources, performance, and cost.
In case workloads are changing, and are hardly predictable it can choose serverless AWS Aurora instances configuration. It allows scaling up and scaling down DB instances in the clusters elastically, transparently, and automatically according to the actual load. The Aurora serverless configuration uses minimal and maximum ACUs (Aurora Compute Units). Each ACU is associated with allocated CPU, memory, and networking. Once the workload of the DB instance increases, there is a demand for more resources, and the DB instance scales up automatically according to the configured ACUs range. Once the workload decreases, the AWS Aurora scales down automatically. It allows one to adjust performance better and helps to keep the optimal cost.
AWS Aurora’s I/O-Optimized storage configuration allows predictable pricing for applications and improved price performance, significant cost savings for I/O-intensive applications.
AWS Aurora's original failover mechanism deserves special attention. In case of a possible outage Aurora automatically performs failover to a reader DB instance in the same cluster. In case no reader exists in the cluster, it will create it automatically in case of failover. In case there are a few readers in the cluster the tier DB instance configuration parameter defines the priority of the failover. AWS Aurora ensures that the failover will not require changing the connection string on the application side. In addition, in the case of global database configuration, Aurora allows failover to another region.

A forma geral do laço while:
```
while(condição) instrução;
```
- condição é uma expressão booleana que controla o laço.
- instrução pode ser uma única instrução ou um bloco de instruções.
- O laço repete enquanto a condição for verdadeira.
**Exemplo Simples**
Exibe o alfabeto usando um laço while:
```
// Demonstra o laço while.
class WhileDemo {
public static void main(String args[]) {
char ch = 'a'; // inicializa ch com 'a'
while(ch <= 'z') { // condição para o laço
System.out.print(ch); // exibe ch
ch++; // incrementa ch
}
}
}
```
**Funcionamento:**
- ch é inicializado com 'a'.
- A cada iteração, ch é exibido e incrementado.
- O laço continua até ch ser maior que 'z'.
**Características do Laço while**
Verifica a condição no início do laço.
O código dentro do laço pode não ser executado se a condição for falsa desde o início.
Elimina a necessidade de um teste separado antes do laço.
**Exemplo de Potências de 2**
Calcula as potências inteiras de 2 de 0 a 9:
```
// Calcula as potências inteiras de 2.
class Power {
public static void main(String args[]) {
int e;
int result;
for(int i = 0; i < 10; i++) {
result = 1;
e = i;
while(e > 0) { // enquanto e for maior que 0
result *= 2; // multiplica result por 2
e--; // decrementa e
}
System.out.println("2 to the " + i + " power is " + result);
}
}
}
```
**Funcionamento:**
- result é inicializado com 1.
- e recebe o valor de i.
- Enquanto e for maior que 0, result é multiplicado por 2 e e é decrementado.
- O laço while não é executado se e for 0.
Saída do Programa: A saída do programa mostra as potências de 2 de 0 a 9
O laço while é ignorado quando e é 0, como na primeira iteração do laço for.
**Conclusão**
- O laço while é útil para repetir um bloco de código enquanto uma condição for verdadeira.
- Pode ser usado de forma eficiente para realizar operações iterativas, como mostrar o alfabeto ou calcular potências.

1,921,954 | Why Buying Instagram Followers in the UK Can Boost Your Social Media Strategy | In the ever-evolving landscape of social media marketing, Instagram stands as a powerful platform for... | 0 | 2024-07-13T05:27:58 | https://dev.to/social-viral/why-buying-instagram-followers-in-the-uk-can-boost-your-social-media-strategy-2mi9 | buyinstagramfollowers, buyfollower, programming, beginners | In the ever-evolving landscape of social media marketing, Instagram stands as a powerful platform for individuals and businesses alike to showcase their brand, connect with audiences, and drive engagement. With over a billion active users globally, Instagram offers unparalleled opportunities for visibility and growth, making it a key battleground for digital marketing success.
One of the most discussed strategies for accelerating growth on Instagram is purchasing followers. This practice has sparked debates within the marketing community, with proponents highlighting its potential benefits and detractors cautioning against potential pitfalls. In this article, we delve into the phenomenon of buying Instagram followers in the UK, exploring its rationale, implications, and effectiveness as a strategy for enhancing social media presence.
**Understanding the Appeal**
The appeal of [buy Instagram followers uk](https://socialviral.uk) in its promise to expedite the growth trajectory of an account. For individuals and businesses looking to establish credibility quickly, a larger follower count can serve as social proof of popularity and influence. In a competitive digital landscape, where perception often shapes reality, a substantial follower base can attract organic followers, engagement, and partnerships.
The Mechanics Behind Buying Instagram Followers
The process typically involves engaging with third-party services that offer packages of followers at varying price points. These followers are often generated through automated accounts (bots) or real accounts incentivized to follow through mutual engagement agreements. While the specifics can vary, the core idea is to increase follower numbers rapidly.
**Benefits of Buying Instagram Followers**
1. **Social Proof and Perception:** A higher follower count can create an initial impression of popularity and credibility, encouraging others to follow and engage with the account.
2. **Kickstarting Growth:** Starting with a larger follower base can expedite organic growth, as the account appears more established and trustworthy to potential followers.
3. **Enhanced Visibility:** Accounts with more followers are more likely to appear in search results and explore pages, increasing the likelihood of attracting new, organic followers.
Potential Drawbacks and Considerations
While buying Instagram followers can offer initial benefits, it's essential to consider the potential drawbacks:
1. **Quality of Followers:** Purchased followers may not be genuinely interested in the content, resulting in low engagement rates and limited interaction.
2. **Risk of Penalties:** Instagram's terms of service prohibit the use of third-party services to generate fake engagement. Accounts found violating these terms may face penalties, including account suspension or shadowbanning.
3. **Long-Term Viability: **Sustainable growth on Instagram relies on genuine engagement and connection with an audience. Relying solely on purchased followers can hinder long-term success.
**Strategies for Effective Use
**To maximize the benefits and minimize risks associated with buying Instagram followers, consider these strategies:
1. **Targeted Approach:** Choose services that offer targeted followers based on demographics, interests, or location, such as buying Instagram followers specifically in the UK to align with your target audience.
2. **Balance with Organic Growth:** Supplement purchased followers with organic strategies such as creating compelling content, engaging with followers, and participating in relevant communities.
3. **Monitor Engagement Metrics:** Track engagement rates, comments, and shares to gauge the quality of interactions and adjust strategies accordingly.
Ethical Considerations
The ethical implications of buying Instagram followers are significant. While it can provide a temporary boost in visibility, it's crucial to prioritize authenticity and genuine connection with your audience. Building a loyal following organically fosters trust and credibility, which are integral to sustainable success in digital marketing.
**Conclusion**
Buying Instagram followers in the UK can be a contentious strategy, with potential benefits and risks to consider. While it can jumpstart visibility and social proof, it should be approached cautiously, keeping long-term goals and ethical considerations in mind. Ultimately, a balanced approach that combines purchased followers with organic growth strategies is key to unlocking sustained success on Instagram.
As Instagram continues to evolve and algorithms change, adapting and refining your approach will be essential. By understanding the nuances of buying followers and integrating them into a holistic social media strategy, individuals and businesses can navigate the complexities of digital marketing with confidence and purpose.

Too tight can be painful and restrict circulation. Too loose and you could lose this precious token of your love. If the sizing is right, your wedding ring will fit wonderfully and be proudly worn every day.
You want your wedding band to be perfect when you buy it. Sizing matters for many reasons:
**1. COMFORT:**
Unfit rings can cause blisters, calluses, and pain.
**2. SECURITY:**
While a tight ring might become caught and cause swelling, a loose ring can easily slip off and get lost.
**3. APPEARANCE:**
A well-fitting ring displays its beauty and design as intended when it rests comfortably on your finger.
**4. LONGEVITY:**
Over time, frequent resizing or adjustments may cause the ring to lose strength. Its integrity and look can be preserved by making sure it fits properly from the beginning.
At Nirvana Jewelers Diamond Boutique, every detail matters, especially your wedding ring. Your ring will last a long time and be a beautiful, safe, and comfortable sign of your commitment thanks to our excellent sizing. | david_marcu_29d063c11a089 | |
1,921,963 | The Truth About Learning Python in 2024 | Is Python Still the Golden Ticket? For years, Python has been the darling of the programming... | 0 | 2024-07-13T05:55:50 | https://dev.to/halimshams/the-truth-about-learning-python-in-2024-4m8m | python, programming | **Is Python Still the Golden Ticket?**
---
For years, Python has been the darling of the programming world, touted as the key to unlocking a lucrative career in tech. But with the AI revolution, layoffs, and a shifting market, **is Python still the best bet for programmers**? In this article, we'll give you an objective assessment of Python's current state in the industry and reveal **the real truth about learning programming languages in today's rapidly changing landscape**.
To understand why Python has been so popular, let's take a step back. Python was created in 1991, a time when programming was a far cry from what it is today. Back then, languages like C, C++, and Java were the norm, and **coding was a tough process**. Python changed the game by making programming **easy and accessible**, allowing developers **to achieve complex tasks with just a few lines of code**. This led to a self-reinforcing cycle where Python's popularity made it even more popular, as companies had access to a larger pool of developers.
Today, Python remains a dominant force in industries like **data science, AI, and backend development**. However, with the AI revolution and the rise of "**Big Data**," the landscape is shifting. While AI might seem like a positive trend for Python programmers, the reality is that **most AI development is now centered around existing tools like ChatGPT, rather than building new AI from scratch**. Meanwhile, **"Big Data" is becoming increasingly important**, with companies using Python to analyze and draw insights from massive datasets.
So, **is Python still a viable option for programmers**? The answer is a resounding **‘*yes*’**. According to job data, **Python remains the second most popular programming language, behind JavaScript**. However, the real truth about learning programming languages today is that **it's not just about mastering one language**. With AI democratizing programming, **it's becoming easier for anyone to learn to code**. **What sets successful developers apart is their ability to solve problems with code, think critically, and make the right decisions about what code to write.**
### **The Real Secret to Success as a Python Developer**
In today's market, **it's not enough to just learn Python or build a few simple projects**. To stand out, **you need to be able to sell your skills, showcase your problem-solving abilities**, and demonstrate the character traits that companies look for in a developer. This might seem daunting, but the good news is that it's easier than you think. By focusing on building **real-world projects, highlighting your skills**, and showcasing your unique perspective, you can stand out from the crowd and land your dream job.
### Final thoughts
While Python remains a dominant force in the industry, the **real key to success lies in developing the skills, mindset, and character traits** that companies look for in a developer. Most programmers out there don't even know how to do the basics, like most resumes that I look at, are so bad that **if you just do a couple of the basics right, you'll automatically Stand Out above 95%**, and I know this might sound overwhelming. You can just go out and take these steps and go and apply them yourself. If you're serious about making it happen in 2024, then go explore this article and build these project and put them in your resume:

Remember, these project ideas are just my recommendations which I found quite rare, you might have more brilliant ideas that you’d like to turn them to real life which prioritizing them above any other project is way more better than jumping to these project ideas.

- Em Java, um laço pode não ter um corpo associado, pois uma instrução nula é sintaticamente válida.
**Utilidade**
- Laços sem corpo podem ser usados para operações que são completamente tratadas na expressão do laço.
-Exemplo de laço sem corpo
- O exemplo abaixo soma os números de 1 a 5 usando um laço for sem corpo:
```
class Empty3 {
public static void main(String args[]) {
int i;
int sum = 0;
// soma os números até 5
for (i = 1; i <= 5; sum += i++);
System.out.println("Sum is " + sum);
}
}
```
A saída do programa é: Sum is 15
**Análise do laço**
A soma é realizada completamente dentro da expressão do laço for.
A expressão de iteração sum += i++ faz a adição e o incremento de i:
sum += i++;
**Desmembrando a expressão**
- Essa expressão pode ser entendida como duas partes:
- sum = sum + i; - Adiciona i a sum.
i++; - Incrementa i.
**Importância**
- Instruções desse tipo são comuns em programas Java profissionais.
- Entender e desmembrar essas expressões facilita a compreensão do código.

Why go to the mall when you can search for the product you want just as you would ask to a store employee? Simply **write your query in natural language**, and we’ll show you examples of the products you're looking for. For example, try typing `I need a winter jacket for women` or `I would like a black smartphone with camera`.
The best part is that **the site doesn't requires for a Wix subscription to finish the checkout process** because it's entirely built using Wix elements and Velo APIs.

## Development Journey
Utilizing Wix Studio has helped me accelerating frontend development, significantly reducing time while ensuring a fully responsive design across all devices. JavaScript plays an important role in enhancing user interaction with Wix Studio elements, enabling dynamic features seamlessly. Moreover, our site employs robust security measures, including database's, web methods', and router's security, to safeguard user data and ensure a secure browsing experience.
> Before diving into how I created Mega Mart, it's important to say that I did not install any apps from the Wix Market. While I used `Wix Stores` for saving products to the cart and then retrived them in some pages, I opted to build the product pages, cart, and checkout pages entirely from scratch using Wix Elements.
> **Disclaimer**
> Since this is a demo for the contest, I have only saved 29 products in the database. To get the most out of the AI image product recognition and AI search methods, please first familiarize yourself with the available products in the store. For example, searching for a printer or a hammer might not yield results, as these items are not in the demo database. However, if this project were scaled up for large companies like Home Depot or Walmart, which have thousands of products in their databases, the AI functionalities would perform comprehensive searches and provide a wider range of results.

## How I built it
Developing this ecommerce site wasn't easy, especially given the tight timeline, but I'm proud to have built it with all its functionality within just 2 weeks.
### Home
The first page I developed was the home page, where I aimed to incorporate features commonly found in other ecommerce sites such as showcasing best sellers, new arrivals, and highlighting the benefits of shopping at the store.
Below is an example of how I retrieved data for best sellers and newest products in the code.
```javascript
import wixData from 'wix-data';
import wixWindowFrontend from 'wix-window-frontend';
import wixLocationFrontend from 'wix-location-frontend';
const limit = wixWindowFrontend.formFactor === "Mobile" ? 6 : 5
const bestSellers = (await wixData.query("Products").descending("rating").limit(limit).find()).items
$w('#repeater2').data = bestSellers
$w('#repeater2').onItemReady(($item, itemData, index)=>{
$item('#imageX9').src = itemData.imageUrl[0].src
$item('#imageX9').alt = itemData.name
$item('#text12').text = itemData.name
$item('#text13').text = "$" + itemData.price
$item('#box15').onClick(() => {
wixLocationFrontend.to(`/product/${itemData._id}`)
})
})
const newProucts = (await wixData.query("Products").descending("_createdDate").limit(limit).find()).items
$w('#repeater3').data = newProucts
$w('#repeater3').onItemReady(($item, itemData, index)=>{
$item('#imageX10').src = itemData.imageUrl[0].src
$item('#imageX10').alt = itemData.name
$item('#text15').text = itemData.name
$item('#text14').text = "$" + itemData.price
$item('#box19').onClick(() => {
wixLocationFrontend.to(`/product/${itemData._id}`)
})
})
```
As you can see, the code also includes logic to detect whether the user is browsing on a mobile device or not. In mobile view, the repeaters are displayed in two columns, while in tablet and computer modes, they are arranged in a single row with five columns.
### Login & Register
I believe that the register and login pages should have an intuitive UI/UX interface. If either processes are difficult or frustrating for users, they may leave the site, resulting in a lost sale.
To prevent this, Mega Mart uses a passwordless system. Each time you want to log in, a one-time code will be sent via SMS, call, or email, eliminating the need to remember multiple passwords.
#### Register
```javascript
import { verify, sendVerification } from "backend/twilio.web"
import { register } from "backend/members.web"
$w('#button1').onClick(async () => {
$w('#imageX9').show()
$w('#button1').disable()
if ($w('#box37').isVisible) {
if ($w('#input5').valid) {
$w('#text35').collapse()
const verifyEmailResponse = await verify($w('#input3').value, $w('#input5').value)
const verifyPhoneResponse = await verify($w('#input4').value, $w('#input5').value)
if (verifyEmailResponse || verifyPhoneResponse) {
try {
const sessionToken = await register($w('#input1').value, $w('#input2').value, $w('#input3').value, $w('#input4').value)
await authentication.applySessionToken(sessionToken)
} catch (error) {
$w('#text35').text = "Error registering: " + new Error(error).message
$w('#text35').expand()
}
} else {
$w('#text35').text = "Wrong verification code."
$w('#text35').expand()
}
}
} else {
const sendEmailResponse = await sendVerification("email", $w('#input3').value)
const sendSMSResponse = await sendVerification("sms", $w('#input4').value)
if (sendEmailResponse && sendSMSResponse) {
$w('#input1,#input2,#box36').collapse()
$w('#box37').expand()
$w('#button1').label = "Register"
$w('#text37').hide()
}
}
$w('#imageX9').hide()
$w('#button1').enable()
})
```
This code handles the registration process when the button is clicked. If the `verification code input box` is visible and the verification code input is valid, it verifies the user's email or phone number with the provided verification code. If either verification is successful, it attempts to register the user and then apply a session token for authentication. If the verification fails, an error message is displayed.
If the box is not visible, it sends verification codes to the user's email and phone, then updates the UI to allow the user to complete the registration.
#### Login
**Sending verification code to user**
```javascript
import { sendVerification } from "backend/twilio.web"
import { verifyEmailOrPhoneNumber} from "backend/members.web"
$w('#button2,#button3').onClick(async (rest) => {
if ($w('#input7').valid || $w('#input8').valid) {
$w('#imageX10').show()
$w('#text34').collapse()
$w('#button2,#button3').disable()
let toSearch = $w('#input7').isVisible ? $w('#input7').value : $w('#input8').value
if (!(await verifyEmailOrPhoneNumber(toSearch))) {
$w('#text34').text = "There isn't an account with that email or phone number."
$w('#text34').expand()
} else {
switch (rest.target) {
case $w('#button2'):
let response = false
if ($w('#input7').isVisible) {
response = await sendVerification("email", $w('#input7').value)
verificationTypeAtLogin = "email"
$w('#text31').text = "Please check you email. It may be at junk mails."
} else {
response = await sendVerification("sms", $w('#input8').value)
verificationTypeAtLogin = "sms"
$w('#text31').text = "Please check you SMS."
}
if (response) {
$w('#text33,#box41,#box47').collapse()
$w('#box46,#box48').expand()
$w('#text36').hide()
} else {
$w('#text34').text = "We couldn't send the verification code. Try using another method."
$w('#text34').expand()
}
break;
case $w('#button3'):
verificationTypeAtLogin = "call"
$w('#text31').text = "You will receive a phone call in a few moments."
if (await sendVerification("call", $w('#input8').value)) {
$w('#text33,#box41,#box47').collapse()
$w('#box46,#box48').expand()
$w('#text36').hide()
} else {
$w('#text34').text = "We couldn't send the verification code. Try using another method."
$w('#text34').expand()
}
break;
}
}
$w('#imageX10').hide()
$w('#button2,#button3').enable()
}
})
```
It first verifies the existence of the entered email or phone number.
Depending on which button is clicked, it sends a verification code via email, SMS, or call. Then it expands `verification code input` for the user to write the received code.
If verification fails, an appropriate error message is displayed. Finally, the loading image is hidden, and the buttons are re-enabled.
**Verifying verification code**
```javascript
import { verify } from "backend/twilio.web"
import { login } from "backend/members.web"
if ($w('#input9').valid) {
$w('#imageX11').show()
$w('#text34').collapse()
$w('#button4').disable()
let verifyResponse = false
if (verificationTypeAtLogin === "email") verifyResponse = await verify($w('#input7').value, $w('#input9').value)
else verifyResponse = await verify($w('#input8').value, $w('#input9').value)
if (verifyResponse) {
try {
const sessionToken = await login(verificationTypeAtLogin === "email" ? $w('#input7').value : "", verificationTypeAtLogin !== "email" ? $w('#input8').value : "")
await authentication.applySessionToken(sessionToken)
} catch (error) {
$w('#text34').text = "Error registering: " + new Error(error).message
$w('#text34').expand()
$w('#imageX11').hide()
$w('#button4').enable()
}
} else {
$w('#text34').text = "Wrong verification code."
$w('#text34').expand()
$w('#imageX11').hide()
$w('#button4').enable()
}
}
```
It verifies the provided code based on the verification type (email or phone). If verification is successful, it attempts to log the user in and apply the session token for authentication.
#### Redirecting the user
Whether the user is logging in or registering, after a successful process, they will be redirected to the last page they visited.
```javascript
import { authentication } from "wix-members"
import wixLocationFrontend from 'wix-location-frontend'
authentication.onLogin(() => {
wixLocationFrontend.to(wixLocationFrontend.query.redirect)
})
```
### Search bar window
In order to allow users to search for products from any page, I added the search bar inside a lightbox.
#### Search type
First check what search type the user selected.
```javascript
import wixWindowFrontend from 'wix-window-frontend';
$w('#imageX7').hide()
$w('#button2,#input1,#searchByImage,#searchByAI').enable()
const type = wixWindowFrontend.lightbox.getContext()
let instructions = ""
switch (type) {
case "text":
$w('#searchByTextMobile').show("fade", { duration: 500 })
instructions = "Enter keywords or product names into the search bar."
break;
case "image":
$w('#searchByImage').show("fade", { duration: 500 })
instructions = "Upload an image of the product you are looking for."
break;
case "AI":
$w('#searchByAI').show("fade", { duration: 500 })
instructions = "Type your query in natural language (e.g., 'I need a winter jacket for women')."
break;
}
$w('#text21').text = `Search by ${type}`
$w('#text22').text = instructions
```
#### Handle search type
**By image**
```javascript
import { getImageLabels } from "backend/googleVision.web"
$w('#searchByImage').onChange(async () => {
$w('#searchByImage').disable()
$w('#imageX7').show()
const file = await $w('#searchByImage').uploadFiles()
const labels = await getImageLabels(file[0].fileUrl)
sendTo("tags", labels)
})
```
First, the image is uploaded to the Media Manager to obtain its URL. Then, the URL is sent to Google Vision to identify tags related to the image.
**By AI**
```javascript
$w('#searchByAI').onKeyPress(async (rest) => {
if ($w('#searchByAI').valid && rest.key === "Enter") {
$w('#searchByAI').disable()
$w('#imageX7').show()
const labels = await getTextLabels($w('#searchByAI').value)
sendTo("tags", labels)
}
})
```
If the user presses `Enter`, the input text is tokenized to extract nouns.
#### Search redirection
Once one of the methods is completed, the user is redirected to the `search router page` with the queries included in the URL.
```javascript
import wixLocationFrontend from 'wix-location-frontend';
function sendTo(type = "", value = []) {
wixLocationFrontend.to(`/search?type=${type}&value=${JSON.stringify(value)}`)
}
```
### Search page
This is a `Wix Router page` that helped me show the different types of search, and also the wishlist of the products the user saved.
#### Repeater display
```javascript
import wixWindowFrontend from 'wix-window-frontend';
import { cart } from "wix-stores-frontend";
let originalItem = wixWindowFrontend.getRouterData()
let items = wixWindowFrontend.getRouterData()
initRepeater(items)
$w('#repeater1').onItemReady(async ($item, itemData, index) => {
$item('#imageX9').src = itemData.imageUrl[0].src
$item('#text12').text = itemData.name
$item('#text13').text = "$" + itemData.price
$item('#ratingsDisplay1').rating = itemData.rating
$item('#button1').onClick(async () => {
const product = [{
productId: itemData._id,
quantity: 1,
}]
await cart.addProducts(product)
await showAlert("add")
})
$item('#box38').onClick(() => {
wixLocationFrontend.to(`/product/${itemData._id}`)
})
if (authentication.loggedIn()) {
const userID = await currentMember.getMember({ fieldsets: ["FULL"] })
const item = await wixData.query("Wishlist").eq("product", itemData._id).eq("_owner", userID._id).find()
if (item.totalCount === 0) $item('#button2').expand()
else {
itemData.wishList = item.items[0]._id
$item('#button3').expand()
}
} else $item('#button2').expand()
$item('#button2').onClick(async () => {
if (authentication.loggedIn()) {
const itemWishlist = await wixData.insert("Wishlist", { product: itemData._id })
itemData.wishList = itemWishlist._id
await showAlert("save")
$item('#button2').collapse().then(() => {
$item('#button3').expand()
})
} else wixWindowFrontend.openLightbox("loginToWishlist")
})
$item('#button3').onClick(async () => {
await wixData.remove("Wishlist", itemData.wishList)
await showAlert("remove")
$item('#button3').collapse().then(() => {
$item('#button2').expand()
})
})
})
function initRepeater(items = [], changeFilter = true) {
$w('#repeater1').data = items
if ($w('#repeater1').data.length === 0) {
if (wixLocationFrontend.query.type === "wishlist") {
$w('#text27').text = "You haven't add any item to your wishlist. Add your first product!"
} else {
$w('#text27').text = "Try searching with another method or include more details if you are using AI."
}
$w('#section5').collapse()
$w('#section6').expand()
} else {
const htmlLinks = items[0].tags.slice(0, 5).map(word => `<span style="font-size: 10px;"><a href="/search?type=tags&value=[%22${word}%22]">${word}</a></span>`).join(' - ');
$w('#text22').html = htmlLinks
$w('#section6').collapse()
$w('#section5').expand()
$w('#switch1').checked = false
if (changeFilter) {
const maxPrice = sortByPrice(items, "desc")[0]
$w('#slider1').max = maxPrice.price
$w('#slider2').max = maxPrice.price
$w('#slider2').value = maxPrice.price
}
}
}
```
As you can see, this includes the `import { cart } from "wix-stores-frontend"` statement, which allows the product to be added to the cart when the user clicks the button inside the repeater.
#### Sort products
```javascript
$w('#switch1').onChange(() => {
$w('#repeater1').data = []
items = sortByPrice(items, $w('#switch1').checked ? "desc" : "asc")
$w('#repeater1').data = items
})
function sortByPrice(products = [{}], order = 'asc') {
return products.sort((a, b) => {
if (order === 'asc') {
return a.price - b.price;
} else if (order === 'desc') {
return b.price - a.price;
} else {
throw new Error("Order must be either 'asc' or 'desc'");
}
});
}
```
#### Filter products
```javascript
$w('#slider1,#slider2').onChange(() => {
items = filterByPriceRange(originalItem, $w('#slider1').value, $w('#slider2').value)
initRepeater(items, false)
})
function filterByPriceRange(products, minPrice, maxPrice) {
return products.filter(product => product.price >= minPrice && product.price <= maxPrice);
}
```
#### Wixlocation.onChange()
Since searching for new products redirects the user to the same page `/search` and only changes the URL queries, I needed to handle this with `wixLocationFrontend.onChange()` to update the repeater items.
### Product page
This is also a router page `/product/${productID}` that fetches product information from the backend and displays it using `wixWindowFrontend.getRouterData()`.
```javascript
import wixWindowFrontend from 'wix-window-frontend';
const product = wixWindowFrontend.getRouterData()
$w('#gallery1').items = product.imageUrl
$w('#features').text = product.features
$w('#title').text = product.name
$w('#brand').text = product.brand
$w('#color').text = product.color
$w('#price').text = String(product.price)
$w('#description').text = product.description
$w('#ratings').rating = product.rating
$w('#stock').text = `${product.stock} available`
```
Since you can add the product to your cart from here, with the option to set a quantity, I used the following code to achieve this.
```javascript
import { cart } from "wix-stores-frontend"
$w('#addCart').onClick(async () => {
const productToSave = [{
productId: product._id,
quantity: Number($w('#inputQuantity').value),
}]
await cart.addProducts(productToSave)
await showAlert("add")
})
$w('#quantityLess,#quantityMore').onClick((rest) => {
let value = Number($w('#inputQuantity').value)
switch (rest.target) {
case $w('#quantityLess'):
if (value > 1) value--
break;
case $w('#quantityMore'):
value++
break;
}
$w('#inputQuantity').value = String(value)
})
```
Also having the option to add the product to the wishlist or delete it.
```javascript
$w('#addWishList').onClick(async () => {
if (authentication.loggedIn()) {
await wixData.insert("Wishlist", { product: product._id })
await showAlert("save")
$w('#addWishList').collapse().then(() => {
$w('#deleteWishlist').expand()
})
} else wixWindowFrontend.openLightbox("loginToWishlist")
})
$w('#deleteWishlist').onClick(async () => {
await wixData.remove("Wishlist", product.wishList)
await showAlert("remove")
$w('#deleteWishlist').collapse().then(() => {
$w('#addWishList').expand()
})
})
```
### Cart page
Need to review your cart? This page allows you to check if you have added the desired quantities of the products you want to buy and also lets you delete any items if needed.
```javascript
import { cart } from "wix-stores-frontend"
$w('#repeater1').onItemReady(($item, itemData, index) => {
$item('#quantityLess,#quantityMore').onClick(async (rest) => {
$item('#quantityLess,#quantityMore,#button3').disable()
let value = Number($item('#inputQuantity').value)
switch (rest.target) {
case $item('#quantityLess'):
if (value > 1) value--
break;
case $item('#quantityMore'):
value++
break;
}
$item('#inputQuantity').value = String(value)
$item('#text22').text = `$${(itemData.price * value).toFixed(2)}`
const updadedCart = await cart.updateLineItemQuantity(Number(itemData._id), value)
$item('#quantityLess,#quantityMore,#button3').enable()
$w('#text25').text = `Total: $${updadedCart.totals.total.toFixed(2)}`
})
$item('#button3').onClick(async () => {
$item('#quantityLess,#quantityMore,#button3').disable()
await cart.removeProduct(Number(itemData._id))
await initCart()
})
})
```
Clicking the buttons `#quantityLess` and `#quantityMore` triggers an event to edit the product quantity. Clicking the `#button3` removes the product from the cart.
### Checkout
This is the final step for purchasing at Mega Market.
If the user is a Site Member, it retrieves their saved addresses and accumulated cashback from their account.
```javascript
import { authentication, currentMember } from "wix-members-frontend"
if (authentication.loggedIn()) {
$w('#text25').collapse()
const user = await currentMember.getMember({ fieldsets: ["FULL"] })
$w('#input1').value = user.contactDetails.firstName
$w('#input2').value = user.contactDetails.lastName
$w('#input3').value = user.loginEmail
$w('#input4').value = user.contactDetails.phones[0]
const addresses = await getUserAdderess(user._id)
if (addresses.length === 0) {
$w('#dropdown1').options = [{ value: "No addresses founded", label: "No addresses founded" }]
$w('#dropdown1').value = "No addresses founded"
$w('#dropdown1').disable()
} else {
const addressesOptions = addresses.map(address => ({
label: `${address.addressLine} ${address.state}, ${address.country}`,
value: JSON.stringify(address)
}));
$w('#dropdown1').options = addressesOptions
}
const totalCashback = await getTotalCashback(user._id)
if (totalCashback === 0) {
$w('#switch1').disable()
$w('#switch1').checked = false
$w('#text28').text = `You will earn $${Number(currentCart.totals.total * 0.01).toFixed(2)} in cashback with this order.`
} else {
cashback = totalCashback > currentCart.totals.total ? currentCart.totals.total : totalCashback;
$w('#switch1').enable()
$w('#text28').text = `Use my cashback: $${Number(cashback).toFixed(2)}`
}
}
```
It also validates that the card number of the user is a Master Card, Visa or AMEX.
```javascript
$w('#input10').onCustomValidation((value, reject) => {
const cardsInfo = {
"Unknown": {
"image": "https://static.wixstatic.com/media/4c0a11_600a3b93f607463296a7c9149268800e~mv2.gif",
"regex": /^\d+$/,
"length": 16
},
"Master Credit": {

"Master Debit": {

"regex": ,
"length": 16
}
}
const cardCategory = identifyCardCategory(value)
$w('#imageX8').src = cardsInfo[cardCategory].image
$w('#input10').maxLength = cardsInfo[cardCategory].length
if (!cardsInfo[cardCategory].regex.test(value)) {
reject("Invalid card number")
}
})
function identifyCardCategory(cardNumber) {
const patterns = {
masterCredit: ,
visaCredit: ,
amex: ,
visaDebit: ,
masterDebit:
};
if (patterns.masterCredit.test(cardNumber)) return "Master Credit";
if (patterns.visaCredit.test(cardNumber)) return "Visa Credit";
if (patterns.amex.test(cardNumber)) return "AMEX";
if (patterns.visaDebit.test(cardNumber)) return "Visa Debit";
if (patterns.masterDebit.test(cardNumber)) return "Master Debit";
return "Unknown";
}
```
After the user inputs all the required information, it's time to process the order.
```javascript
$w('#button2').onClick(async () => {
if ($w('#input1').valid && $w('#input2').valid && $w('#input3').valid && $w('#input4').valid && $w('#input5').valid && $w('#input6').valid && $w('#input7').valid && $w('#input8').valid && $w('#input9').valid && $w('#input10').valid && $w('#dropdown2').valid && $w('#dropdown3').valid && $w('#dropdown4').valid) {
$w('TextInput,Dropdown').disable()
$w('#box53').show()
const productArray = currentCart.lineItems.map(item => ({
quantity: item.quantity,
name: item.name,
priceData: {
price: item.price,
},
mediaItem: {
src: item.mediaItem.src
}
}));
const insertedItem = await wixData.insert("Orders", {
lineItems: productArray,
totals: {
subtotal: subTotal,
total: total,
},
shippingInfo: {
shipmentDetails: {
address: {
city: $w('#dropdown4').value,
country: $w('#dropdown2').value,
addressLine: $w('#input5').value,
postalCode: $w('#input6').value,
subdivision: $w('#dropdown3').value,
}
}
},
billingInfo: {
address: {
city: $w('#dropdown4').value,
country: $w('#dropdown2').value,
addressLine: $w('#input5').value,
postalCode: $w('#input6').value,
subdivision: $w('#dropdown3').value,
},
lastName: $w('#input2').value,
firstName: $w('#input1').value,
email: $w('#input3').value,
phone: $w('#input4').value
},
cashback: $w('#switch1').checked
})
for (let lineItem of currentCart.lineItems) {
await cart.removeProduct(lineItem.id)
}
wixLocationFrontend.to(`/order/${insertedItem._id}`)
}
})
```
This `wixData.insert()` triggers a data hook that creates the order using `wixStoresBackend.createOrder()` which I'll talk of it later.
### Order page
This page displays the order information passed though the `wixWindowFrontend.getRouterData()`.
```javascript
import wixWindowFrontend from 'wix-window-frontend';
const orderInfo = wixWindowFrontend.getRouterData()
const contact = orderInfo.billingInfo
const shipping = contact.address
$w('#text21').text = `Order #${orderInfo.orderNumber}`
$w('#text48').text = `Amount paid: $${orderInfo.totals.total}`
$w('#text47').text = `Subtotal: $${Number(orderInfo.totals.subtotal).toFixed(2)} | Discounts: $${Number(orderInfo.totals.subtotal - orderInfo.totals.total).toFixed(2)}`
$w('#text26').text = contact.firstName
$w('#text27').text = contact.lastName
$w('#text28').text = contact.phone
$w('#text29').text = contact.email
$w('#text30').text = shipping.addressLine
$w('#text31').text = shipping.city
$w('#text32').text = shipping.postalCode
$w('#text33').text = `${shipping.subdivision}, ${shipping.country}`
```

1,921,973 | Reinforcement Learning in AI: Algorithms and Applications | Artificial intelligence (AI) has numerous branches, each contributing to its incredible advancements.... | 0 | 2024-07-13T06:12:00 | https://dev.to/fizza_c3e734ee2a307cf35e5/reinforcement-learning-in-ai-algorithms-and-applications-2fd5 | ai, algorithms, machinelearning |
Artificial intelligence (AI) has numerous branches, each contributing to its incredible advancements. Among these, reinforcement learning (RL) stands out for its unique approach to problem-solving, enabling machines to learn from their actions and experiences. This blog will delve into the fundamentals of reinforcement learning, its algorithms, and its applications across various industries. If you are intrigued by AI and want to dive deeper into this field, a [data science specialization certificate](https://www.example.com) could be your gateway to mastering these cutting-edge technologies.
**What is Reinforcement Learning?**
Reinforcement learning is a type of machine learning where an agent learns to make decisions by performing actions and receiving feedback from its environment. Unlike supervised learning, which relies on a labeled dataset, RL focuses on learning from interactions and optimizing for long-term rewards.
**The key components of RL are:**
- _**Agent**:_ The learner or decision-maker.
- _**Environment**:_ The external system the agent interacts with.
- _**Actions**:_ The set of all possible moves the agent can make.
- _**Rewards**:_ The feedback the agent receives from the environment after acting.
-_ **States**:_ The different situations in which the agent can find itself.
- _**Policy**:_ The strategy the agent employs to determine the next action based on the current state.
**Key Algorithms in Reinforcement Learning**
1. **Q-Learning**
Q-Learning is a value-based RL algorithm where the agent learns the value of taking a particular action in a particular state. It updates the Q-values using the Bellman equation to converge to the optimal action-value function.
\[
Q(s, a) \leftarrow Q(s, a) + \alpha \left[ r + \gamma \max_{a'} Q(s', a') - Q(s, a) \right]
\]
Here, \( \alpha \) is the learning rate, \( \gamma \) is the discount factor, \( r \) is the reward, and \( s' \) is the new state.
2. **Deep Q-Networks (DQN)**
DQN combines Q-Learning with deep neural networks to handle high-dimensional state spaces. This algorithm employs a neural network to approximate the Q-value function and uses experience replay and target networks to stabilize training.
3. **Policy Gradient Methods**
Policy gradient methods directly optimize the policy (the agent's behavior) by adjusting its parameters based on the received rewards. The agent learns a probability distribution over actions and uses gradient ascent to maximize the expected reward.
\[
\nabla J(\theta) = \mathbb{E}_{\pi_\theta} \left[ \nabla \log \pi_\theta(a|s) R \right]
\]
4. **Actor-Critic Methods**
Actor-critic methods combine the advantages of value-based and policy-based approaches. The "actor" updates the policy directly, while the "critic" evaluates the action taken by the actor, providing a gradient signal to improve the policy.
**Applications of Reinforcement Learning**
1. **Gaming**
RL has shown remarkable success in gaming, with AI agents achieving superhuman performance in games like Go and Chess, and video games such as Dota 2 and StarCraft II. These agents use RL algorithms to learn strategies and improve their gameplay through extensive simulations.
2. **Robotics**
In robotics, RL enables robots to learn complex tasks such as walking, grasping objects, and navigating through environments. By learning from trial and error, robots can adapt to new tasks and improve their performance over time.
3. **Finance**
Financial markets are dynamic and uncertain, making them ideal for RL applications. RL algorithms can optimize trading strategies, manage portfolios, and even assist in fraud detection by learning from historical data and market trends.
4. **Healthcare**
In healthcare, RL can optimize treatment strategies, personalize medicine, and manage healthcare resources. For instance, RL algorithms can assist in developing personalized treatment plans for patients by analyzing their medical history and treatment outcomes.
5. **Autonomous Vehicles**
Autonomous vehicles rely on RL to navigate complex environments, make real-time decisions, and ensure passenger safety. RL algorithms help these vehicles learn from their interactions with the environment, improving their ability to handle various driving scenarios.

## Introduction:
JavaScript injection attacks are a significant security threat to web applications. These attacks can lead to data breaches, unauthorized actions, and various other security issues. I will guide you through advanced techniques to detect and prevent JavaScript injection attacks. This blog will include real-world example code to help you understand and implement these techniques effectively.
## What is JavaScript Injection?
JavaScript injection occurs when an attacker is able to inject malicious code into a web application. This can happen through various means, such as input fields, URL parameters, or even cookies. Once injected, the malicious code can execute within the context of the web application, potentially leading to data theft, unauthorized actions, and other harmful consequences.
## Common Types of JavaScript Injection Attacks:
**1. Cross-Site Scripting (XSS):** Injecting malicious scripts into web pages viewed by other users.
**2. DOM-Based XSS:** Manipulating the DOM environment to execute malicious JavaScript.
**3. SQL Injection:** Injecting SQL commands that can execute arbitrary queries on the database.
## Detecting JavaScript Injection Attacks:
### 1. Input Validation:
- Validate all user inputs on both the client and server sides.
- Use regular expressions to ensure inputs meet expected formats.
```js
function validateInput(input) {
const regex = /^[a-zA-Z0-9_]*$/; // Example regex for alphanumeric and underscore
return regex.test(input);
}
const userInput = document.getElementById('user-input').value;
if (!validateInput(userInput)) {
alert('Invalid input');
}
```
### 2. Content Security Policy (CSP):
Implement CSP to control the sources from which JavaScript can be loaded and executed.
```js
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self'">
```
### 3.Escaping User Input:
Escape all user inputs to prevent the execution of malicious scripts.
```js
function escapeHTML(input) {
const div = document.createElement('div');
div.appendChild(document.createTextNode(input));
return div.innerHTML;
}
const safeInput = escapeHTML(userInput);
document.getElementById('output').innerHTML = safeInput;
```
## Preventing JavaScript Injection Attacks:
### 1. Use Prepared Statements:
For SQL queries, use prepared statements to avoid SQL injection.
```js
const query = 'SELECT * FROM users WHERE username = ?';
db.execute(query, [username], (err, results) => {
// Handle results
});
```
### 2. Sanitize User Inputs:
Use libraries like DOMPurify to sanitize HTML and prevent XSS attacks.
```js
const cleanInput = DOMPurify.sanitize(userInput);
document.getElementById('output').innerHTML = cleanInput;
```
### HTTP-Only Cookies:
Use HTTP-only cookies to prevent access to cookies via JavaScript.
```js
document.cookie = "sessionId=abc123; HttpOnly";
```
### 4. Limit JavaScript Capabilities:
Use features like Subresource Integrity (SRI) to ensure that only trusted scripts are executed.
```js
<script src="https://example.com/script.js" integrity="sha384-oqVuAfXRKap7fdgcCY5uykM6+R9GqQ8K/uxAuNS8mFLdtfiP4uH90+U8IsrK4QR" crossorigin="anonymous"></script>
```
## Example:
Consider a simple login form that could be susceptible to JavaScript injection. Here's how you can secure it:
### HTML:
```html
<form id="login-form" method="POST" action="/login">
<label for="username">Username:</label>
<input type="text" id="username" name="username" required>
<label for="password">Password:</label>
<input type="password" id="password" name="password" required>
<button type="submit">Login</button>
</form>
```
### JavaScript:
```js
document.getElementById('login-form').addEventListener('submit', function(event) {
const username = document.getElementById('username').value;
const password = document.getElementById('password').value;
if (!validateInput(username) || !validateInput(password)) {
alert('Invalid input');
event.preventDefault();
}
});
function validateInput(input) {
const regex = /^[a-zA-Z0-9_]*$/;
return regex.test(input);
}
```
### Server-Side (Node.js Example):
```js
const express = require('express');
const app = express();
const bodyParser = require('body-parser');
const mysql = require('mysql');
const db = mysql.createConnection({
host: 'localhost',
user: 'root',
password: '',
database: 'test'
});
app.use(bodyParser.urlencoded({ extended: true }));
app.post('/login', (req, res) => {
const username = req.body.username;
const password = req.body.password;
const query = 'SELECT * FROM users WHERE username = ? AND password = ?';
db.execute(query, [username, password], (err, results) => {
if (err) throw err;
if (results.length > 0) {
res.send('Login successful');
} else {
res.send('Invalid credentials');
}
});
});
app.listen(3000, () => {
console.log('Server is running on port 3000');
});
```
### Conclusion:
Detecting and preventing JavaScript injection attacks is crucial for maintaining the security of your web applications. By implementing the techniques discussed in this blog, you can significantly reduce the risk of such attacks. Remember to validate and sanitize all user inputs, use CSP, HTTP-only cookies, and limit JavaScript capabilities using SRI.

Inspired by the beautiful and functional dashboards I've seen online, I embarked on a journey to personalize my own Home Assistant experience. This post dives into the plugins I used, my customization choices, and a final glimpse of the finished product.
## **Introducing the Plugin Powerhouse**
Several plugins played a pivotal role in building my dream dashboard, each offering unique functionalities that elevated the user experience.
I meticulously handpicked a select few from the vast plugin library, prioritizing consistency and cohesiveness around the versatile [Bubble Card](https://github.com/Clooos/Bubble-Card), to craft this personalized experience.
### Bubble Card

I recently stumbled upon the [Bubble Card](https://github.com/Clooos/Bubble) plugin, and let me tell you, it was a game-changer!
This new plugin quickly became the star of my dashboard makeover. Its cool, rounded design elements totally revamped the whole look and feel, making everything smooth and visually appealing.
To take things to the next level, I also started using the [Bubble](https://github.com/Clooos/Bubble) theme, created by the same awesome creator.
Together, they work like magic, creating a consistent and stunning dashboard that's more than just the sum of its parts.
It's like my dashboard went from info central to an interactive and visually engaging masterpiece!
### Card Mod
Anyone who's ever tinkered with their dashboard to make it look snazzy probably knows about Card Mod – it's kind of a no-brainer.
This awesome plugin lets you, well, mod your cards by taking styles from other cards. Need to change the background color, for example? Card Mod is your new best friend.
It helps if you know a little CSS, but even without it, you can do some pretty cool stuff and make your dashboard look way less, well, boring.
### Decluttering Card
Card Mod is so cool, I went a little overboard and ended up customizing practically everything! But all those tweaks scattered throughout my config started to feel like a bit of a pain to manage.
That's when I discovered the magic of [Decluttering Card](https://github.com/custom-cards/decluttering-card). This plugin lets me create card templates that I can reuse everywhere, shrinking my configuration file down to a much more manageable size.
Now, I can make a change in one place, and it ripples through my entire dashboard – a total win!
### Config Template Card
Decluttering Card definitely helps with the templating issue, but it can't handle everything, especially when things get a little more dynamic.
Thankfully, the [Config Template Card](https://github.com/iantrich/config-template-card) swoops in to save the day! This plugin lets you use JavaScript to make pretty much any property of your card dynamic, putting the finishing touches on your template mastery.
It's like the final ingredient in the recipe for perfect dashboard customization.
### Lovelace Layout Card
Now I have the power to create the perfect cards, I just needed the final touch: a stellar layout.
Thankfully, [Lovelace Layout Card](https://github.com/thomasloven/lovelace-layout-card) swoops in to save the day! This plugin allows me to craft a perfectly responsive dashboard that flawlessly adapts to both my desktop and mobile, ensuring a seamless Home Assistant experience no matter the device I'm using.
## **Bringing it to Life: My Customization Journey**
In the following sections, I'll delve into the specifics of how I utilized these plugins to realize my desired dashboard functionalities.
I'll provide a detailed explanation for each, empowering you to replicate or adapt these approaches to craft your own personalized Home Assistant experience.
### Alarm

Keeping tabs on my home alarm system's status is crucial. To achieve this, I needed a clear and immediate visual indicator right on my dashboard.
The ideal card would dynamically change its background color based on the alarm's state: green for disabled, orange for armed, and red for triggered. Luckily, the style customization of Bubble Card allowed me to create this functionality perfectly.
Now, with just a glance, I can see the alarm's status and take appropriate action if needed.
Here is the decluttering-card template:
```yaml
default:
- name: ''
- columns: 2
card:
type: custom:bubble-card
card_type: button
button_type: state
entity: '[[entity]]'
name: '[[name]]'
show_state: true
icon: mdi:alarm-light
columns: '[[columns]]'
card_layout: large
styles: |
.bubble-button-card-container {
background-color: ${state === 'disarmed' ? 'var(--success-color)' : state === 'triggered' ? 'var(--error-color)' : 'var(--warning-color)'};
}
.bubble-icon {
color: ${state === 'disarmed' ? 'var(--success-color)' : state === 'triggered' ? 'var(--error-color)' : 'var(--warning-color)'} !important;
opacity: 0.6 !important;
}
```
### AQI

Monitoring air quality is a top priority for me, as I'm sensitive to pollution.
Having this data readily available on my dashboard helps me maintain my health, not only through automations with my air purifier but also by allowing me to check the current pollution level at a glance.
I envisioned a card that would display the Air Quality Index (AQI) using a color-coded system: green for good air quality (AQI below 50), orange for moderate air quality (AQI below 100), and red for poor air quality (AQI above 100).
This way, I could easily understand the air quality and take appropriate actions, if necessary.
Here is the decluttering-card template:
```yaml
default:
- name: ''
card:
type: 'custom:bubble-card'
card_type: button
button_type: state
entity: '[[entity]]'
name: '[[name]]'
icon: mdi:leaf
show_state: true
columns: 2
card_layout: large
styles: |
.bubble-button-card-container {
background-color: ${state < 50 ? 'var(--success-color)' : state < 100 ? 'var(--warning-color)' : 'var(--error-color)'};
}
.bubble-icon {
color: ${state < 50 ? 'var(--success-color)' : state < 100 ? 'var(--warning-color)' : 'var(--error-color)'} !important;
opacity: 0.6 !important;
}
```
### Covers

My cover cards demanded a presentation that was both information-rich and visually clear. To achieve this, I implemented a three-pronged approach:
- **Condensed Icon Spacing & Favorite Position Integration:** I tightened the spacing between the cover icons, fostering a sense of cohesion for the linked actions they represent. Additionally, I incorporated a sub-button displaying the favorite position (set at 15% in my case) directly within the card itself.
- **Seamless Opening Percentage Display:** The current opening percentage is crucial information, and I eliminated the need for a separate entity card by integrating it directly into the cover card.
- **Color-Coded Status Recognition:** Finally, I implemented a color-coding system to provide instant status recognition. Blue signifies a fully open cover, while purple highlights the preferred 15% position. This visual language allows for quick comprehension and informed decision-making when interacting with my covers.
This combined approach effectively streamlined the cover card format, enhancing both information accessibility and user experience.
Here is the decluttering-card template:
```yaml
default:

### Separator

To keep my dashboard organized, I grouped things into sections.
Bubble Card's separator mode was perfect for adding section titles, but I wanted to give them a little makeover.
So, I played around with some CSS to make the font lighter and bigger, and tweaked the line color so it stands out even when the cards aren't in a popup.
Now the section titles are easy to read and add a nice touch to the whole thing!
Here is the decluttering-card template:
```yaml
default:
- icon: ''
- name: ''
card:
type: custom:bubble-card
card_type: separator
name: '[[name]]'
icon: '[[icon]]'
card_layout: large
styles: |
.bubble-name {
font-weight: 100;
font-size: 20px;
}
.bubble-line {
background-color: var(--background-color-2, var(--secondary-background-color));
opacity: 0.2;
}
```
### Thermostat

Craving more from my smart thermostat display, I used custom-template-card to dynamically change the card's icon based on heating state.
Color cues joined the party: blue for off, green for achieved comfort, and orange for heating to reach temperature. I even incorporated the target temperature in this customized switch card.
Now, it's a one-stop shop for efficient and comfortable climate control!
```yaml
default:
- name: ''
- offset: 1
card:
type: custom:config-template-card
variables:
MODE: "states['[[entity]]'].state"
entities:
- "[[entity]]"

}
.bubble-state::after {

margin-left: 4px;
}
```
### Weather

While Bubble Card forms the foundation, the true magic lies in the customization of my weather display. It leverages the power of sub-buttons to showcase a range of essential information: current conditions, daily highs and lows, wind speed, and the anticipated rain forecast.
But the key is the intuitive color-coding system I implemented:
- **Temperatures** utilize a blue-to-red gradient, providing a quick glimpse of the expected highs and lows.
- **Wind speed** follows a similar approach, transitioning from neutral to red as intensity increases.
- **Rain** takes center stage with a prominent blue highlight whenever there's a chance of precipitation.
This visual language allows me to grasp the daily forecast at a glance, without getting bogged down in numbers. It's a testament to the power of visual communication and user experience design in action!

### Weather forecast

While the current weather is important, I also crave a sneak peek at the next week's forecast.
To achieve this, I leveraged the same color-coded system from my weather card for a visually cohesive experience. Additionally, I cleverly formatted the current day using its attributes, while also extracting the high and low temperatures from the same source.
This way, I get a clear picture of the upcoming week's weather trends right on my dashboard.
```yaml

1,921,984 | O Laço do-while em Java | Estrutura Geral O laço do-while executa as instruções pelo menos uma vez antes de verificar a... | 0 | 2024-07-13T06:25:23 | https://dev.to/devsjavagirls/o-laco-do-while-em-java-1io3 | java | **Estrutura Geral**
O laço do-while executa as instruções pelo menos uma vez antes de verificar a condição.
A forma geral é:
```
do {
instruções;
} while(condição);
```
**Diferença dos Laços for e while**
- Em for e while, a condição é verificada antes da execução do laço.
- Em do-while, a condição é verificada após a execução do laço, garantindo que ele execute pelo menos uma vez.
**Exemplo Simples**
Um programa que entra em laço até o usuário inserir a letra 'q':
```
// Demonstra o laço do-while.
class DWDemo {
public static void main(String args[]) throws java.io.IOException {
char ch;
do {
System.out.print("Press a key followed by ENTER: ");
ch = (char) System.in.read(); // obtém um char
} while(ch != 'q');
}
}
```
**Jogo de Adivinhação Melhorado**
Um programa de adivinhação que entra em laço até o usuário adivinhar a letra correta:
ver Guess4.java
**Explicação do Programa de Adivinhação**
- O programa lê caracteres do usuário até que a letra correta seja adivinhada.
- Há dois laços do-while:
- O primeiro laço continua até o usuário adivinhar a letra correta.
- O segundo laço descarta caracteres extras do buffer de entrada até encontrar um \n (nova linha).
**Exemplo de Execução**
Execução típica do programa de adivinhação
```
I'm thinking of a letter between A and Z.
Can you guess it: A
...Sorry, you're too low
Try again!
I'm thinking of a letter between A and Z.
Can you guess it: Z
...Sorry, you're too high
Try again!
I'm thinking of a letter between A and Z.
Can you guess it: K
** Right **
```
**Detalhe Importante**
- A entrada do console é armazenada em um buffer de linha, então pressionar ENTER adiciona uma sequência de nova linha que precisa ser descartada.
- O segundo laço do-while remove caracteres extras do buffer para evitar leituras indesejadas.
**Conclusão**
- O laço do-while é útil quando você precisa garantir que o bloco de instruções seja executado pelo menos uma vez.
- Ele é especialmente prático para interações com o usuário onde uma ação inicial é necessária antes da verificação da condição.

1,921,986 | Setting Up Traefik and mkcert for Local Development | Traefik is a powerful HTTP reverse proxy and load balancer that simplifies the deployment of... | 0 | 2024-07-13T07:43:49 | https://dev.to/agusrdz/setting-up-traefik-and-mkcert-for-local-development-48j5 | traefik, docker, mkcert, development | Traefik is a powerful HTTP reverse proxy and load balancer that simplifies the deployment of microservices. While it's widely used in production environments, Traefik is also incredibly useful for local development. When combined with mkcert, a tool for creating locally trusted development certificates, you can create a seamless, secure development environment that mirrors production settings.
In this guide, we'll walk through setting up Traefik and mkcert for local development, focusing on the most relevant features and common issues, such as using APIs or third-party services that require HTTPS.
## Prerequisites
Before starting, ensure you have the following installed on your machine:
1. **Docker**: To containerize your applications.
2. **Docker Compose**: To manage multi-container Docker applications.
3. **External Network**: Create an external Docker network to connect all your services.
You can create the external network with the following command:
```sh
docker network create web
```
> Note: Creating an external network allows you to connect multiple Docker Compose projects to the same network. This way, you don't need to have all your containers in a single docker-compose.yml file or in the same directory. It enables you to use Traefik as a proxy across multiple projects seamlessly.
## Why Use Traefik and mkcert for Local Development?
There are several key benefits to using Traefik and mkcert together:
1. **Simplified Configuration**: Traefik provides an easy way to configure routing rules and manage traffic, using dynamic configuration files that can be updated without restarting the server.
2. **Automatic HTTPS with mkcert**: mkcert generates locally trusted SSL certificates for custom domain names, allowing you to work with HTTPS connections in your local environment without warnings or errors.
3. **Custom Domain Names**: Traefik allows you to define custom domain names for your services, making it easier to manage multiple projects locally.
4. **Load Balancing**: Traefik can distribute traffic among multiple instances of a service, providing load balancing for your applications.
5. **Middleware Support**: Traefik supports middleware plugins that can modify requests and responses, add authentication, rate limiting, and other features.
By using Traefik and mkcert, you can create a local development environment that handles multiple services, ensures secure HTTPS connections, and mimics production conditions.
## Common Issues Addressed
- **APIs and Third-Party Services**: Many APIs and third-party services require HTTPS. Without a proper SSL setup, you may encounter errors when integrating these services locally.
- **Domain Conflicts**: Using custom domain names with Traefik helps avoid conflicts between services running on different ports.
- **Security Warnings**: Browsers often show security warnings for self-signed certificates. mkcert creates certificates trusted by your local machine, eliminating these warnings.
## Setting Up Your Environment
This guide describes how to configure your environment to use Traefik as a reverse proxy with HTTPS connections. Ensure you have `docker-compose` installed to execute the following steps.
### Quick Start
A Makefile can simplify the setup process. You can run the following command from the root directory to install all dependencies and start the services:
```sh
make install
```
Alternatively, you can install each component individually by navigating to each service directory and running `make install`.
## Configuration Files
#### `docker-compose.yml`
To set up Traefik and mkcert in your `docker-compose.yml`, include the following configuration:
```yaml
services:
mkcert:
environment:
- domain=*.home.com,*.site.com,*.local.com
container_name: mkcert
volumes:
- ./certs/:/root/.local/share/mkcert
image: vishnunair/docker-mkcert
labels:
- "traefik.enable=false"
networks:
- web
traefik:
image: traefik:latest
container_name: traefik
ports:
- "80:80"
- "443:443"
- "8080:8080"
volumes:
- "/var/run/docker.sock:/var/run/docker.sock:ro"
- "./config/traefik.yml:/etc/traefik/traefik.yml:ro"
- "./config/dynamic.yml:/etc/traefik/dynamic.yml:ro"
- "./certs/:/etc/certs:ro"
labels:
- "traefik.enable=true"
- "traefik.http.routers.traefik.rule=Host(`traefik.home.com`)"
- "traefik.http.routers.traefik.entrypoints=https"
- "traefik.http.routers.traefik.tls=true"
- "traefik.http.routers.traefik.service=traefik@docker"
- "traefik.http.services.traefik.loadbalancer.server.port=8080"
networks:
- web
networks:
web:
external: true
```
#### traefik.yml
Traefik's main configuration file, `traefik.yml`, should include the following:
```yaml
global:
sendAnonymousUsage: false
api:
dashboard: true
insecure: true
providers:
docker:
endpoint: "unix:///var/run/docker.sock"
watch: true
exposedByDefault: false
file:
filename: /etc/traefik/dynamic.yml
watch: true
log:
level: INFO
format: common
entryPoints:
http:
address: ":80"
http:
redirections:
entryPoint:
to: https
scheme: https
https:
address: ":443"
```
#### dynamic.yml
Traefik's dynamic configuration file, `dynamic.yml`, should include the TLS certificate information:
```yaml
tls:
certificates:
- certFile: "/etc/certs/_wildcard.home.com.pem"
keyFile: "/etc/certs/_wildcard.home.com-key.pem"
- certFile: "/etc/certs/_wildcard.site.com.pem"
keyFile: "/etc/certs/_wildcard.site.com-key.pem"
- certFile: "/etc/certs/_wildcard.local.com.pem"
keyFile: "/etc/certs/_wildcard.local.com-key.pem"
```
### Modify the Hosts File
To properly route the domains to your local environment, add the following entries to your `hosts` file:
```sh
127.0.0.1 traefik.home.com
127.0.0.1 whoami.home.com
127.0.0.1 laravel1.site.com
127.0.0.1 laravel2.site.com
127.0.0.1 laravel3.local.com
127.0.0.1 laravel4.local.com
```
### Add Certificates to Trusted Certificates Store
To avoid security warnings in your browser, you need to add the `.pem` certificate to your trusted certificates store.
- **On macOS**: Open the `.pem` file with Keychain Access and add it to your System or Login keychain. Make sure to mark the certificate as trusted.
- **On Windows**: Run `certutil -addstore -f "ROOT" example.com+1.pem` in the command line as an administrator.
- **On Linux**: The method to add trusted certificates may vary by distribution. A common approach is to copy the `.pem` file to `/usr/local/share/ca-certificates/` and then run `sudo update-ca-certificates`.


## Conclusion
By following these steps and configurations, you can effectively set up Traefik and mkcert to manage multiple services and secure HTTPS connections in your local development environment. This setup not only mimics a production environment but also ensures that you can seamlessly integrate third-party services and APIs that require HTTPS. With Traefik's powerful routing capabilities and mkcert's easy-to-use certificate generation, your local development process will be more efficient, secure, and organized.
For more details and the complete setup, you can check the repository: [https://github.com/AgusRdz/traefik-proxy](https://github.com/AgusRdz/traefik-proxy).

1,921,989 | Hoisting in javascript ? | “Hoisting is behavior in javascript where all the variable and function declaration moved to the top... | 0 | 2024-07-13T06:45:46 | https://dev.to/sagar7170/hoisting-in-javascript--46md | javascript, beginners, webdev | “Hoisting is behavior in javascript where all the variable and function declaration moved to the top of the containing scope during compilation phase before code execution”
You may came across this definition everywhere but “it is a myth that all the variable and function declaration physically top of the code ” This is not true!
But instead , In hoisting all the variable and function declaration already get assigned memory before code execution in the compilation and stay exactly where we typed them.
So exactly how var/let/const and functions are hoisted.
Here are some examples:
```
console.log(a) // undefined
console.log(b) // ReferenceError
console.log(c) // ReferenceError
var a = 10;
let b = 20;
const c = 30;
```
Variable declared with var will be hoisted and during compilation time var variable assigned in memory with value undefined that why when we console var before declaration we get undefined
Variable declared with const/let will also hoisted but not initialized with undefined . we can not access them before declaration , otherwise we receive a ReferenceError. This is because of Temporal Dead Zone, a time where variable exist but not initialized .
But what about function
Well it depends how we declare our functions. See below.
```
greet1();
greet2();
greet3();
greet4();
//function declaration is full hoisted
function greet1(){
console.log("greet1");
}
// TypeError: greet2 is not a function
var greet2 = function(){
console.log("greet2");
}
// ReferenceError: Cannot access 'greet3' before initialization
let greet3 = function(){
console.log("greet2");
}
// ReferenceError: Cannot access 'greet4' before initialization
const greet4 = function(){
console.log("greet2");
}
```
Traditional function declaration is fully hoisted means we can call it throughout the code.
but with function expression , we are unable to it before it has been declared . This is why three function declared with variables gives us an error. So we have two option either we change the function expression to function declaration or call the function after declarations. | sagar7170 |

1,921,992 | Building a Simple To-Do List App with React 🚀 | Introduction: In this tutorial, we'll walk through the process of building a simple to-do list app... | 0 | 2024-07-13T06:50:19 | https://dev.to/devabdul/building-a-simple-to-do-list-app-with-react-2afk | webdev, javascript, beginners, programming | **Introduction:**
In this tutorial, we'll walk through the process of building a simple to-do list app using React. This project will help you understand the basics of React components, state management, and event handling. By the end of this tutorial, you'll have a functional to-do list app that you can further enhance with additional features.
**Prerequisites:**
- Basic knowledge of JavaScript and HTML.
- Node.js installed on your machine.
- A code editor like VS Code.
**Step 1: Setting Up the Project**
First, let's set up our React project using Create React App. Open your terminal and run the following commands:
```bash
npx create-react-app todo-app
cd todo-app
npm start
```
This will create a new React project and start the development server. Open your browser and navigate to `http://localhost:3000` to see the default React app.
**Step 2: Creating the To-Do List Component**
Next, we'll create a new component for our to-do list. Create a new file called `TodoList.js` in the `src` directory and add the following code:
```javascript
import React, { useState } from 'react';
function TodoList() {
const [tasks, setTasks] = useState([]);
const [input, setInput] = useState('');
const addTask = () => {
if (input.trim()) {
setTasks([...tasks, input]);
setInput('');
}
};
return (
<div>
<h1>To-Do List</h1>
<input
type="text"
value={input}
onChange={(e) => setInput(e.target.value)}
placeholder="Enter a new task"
/>
<button onClick={addTask}>Add Task</button>
<ul>
{tasks.map((task, index) => (
<li key={index}>{task}</li>
))}
</ul>
</div>
);
}
export default TodoList;
```
**Step 3: Using the To-Do List Component in App.js**
Now, let's use our `TodoList` component in the main `App.js` file. Open `src/App.js` and update it as follows:
```javascript
import React from 'react';
import TodoList from './TodoList';
import './App.css';
function App() {
return (
<div className="App">
<TodoList />
</div>
);
}
export default App;
```
**Step 4: Adding Some Styling**
To make our app look better, let's add some basic styling. Open `src/App.css` and add the following styles:
```css
.App {
text-align: center;
}
input {
margin-right: 10px;
}
button {
margin-left: 10px;
}
ul {
list-style-type: none;
padding: 0;
}
li {
background: #f4f4f4;
margin: 5px 0;
padding: 10px;
border-radius: 4px;
}
```
**Conclusion:**
That's it! You've built a simple to-do list app with React. You can now add, display, and clear tasks. Feel free to extend this app by adding features like task deletion, task editing, or even persisting tasks in local storage.

**Less Technical Know-How Required:** Clone scripts are designed to be user-friendly, making them accessible even for those with limited technical expertise.
## Consider Appkodes for Your UberEats Clone Script Needs

If you’re considering an UberEats clone script, Appkodes is highly recommended. They offer a range of robust and customizable scripts, including food delivery solutions that can help you hit the ground running.
**Ready-to-Use Solutions:**Get started quickly with pre-built features.
**Customizable Designs:** Tailor the app to suit your brand identity.
**Comprehensive Support:** Benefit from reliable technical support throughout your journey.
**Building from Scratch:** The Challenges
While building an app from scratch allows for full customization, it comes with several drawbacks:
**Time-Consuming:** Developing an app from the ground up can take months or even years.
**Higher Costs:** The expense of hiring developers, designers, and project managers adds up quickly.
**Complexity:** Requires extensive technical knowledge and resources to manage coding, testing, and deployment.
## In Summary

Choosing between an UberEats clone script and building from scratch ultimately depends on your goals, budget, and timeline. For many entrepreneurs, clone scripts offer a practical and efficient solution that can help bring your food delivery app vision to life without the headaches of traditional development.

1,921,998 | The Future of Meme Coin Development Company | Inspired by Internet memes and jokes, cryptocurrency memes have gained immense popularity in recent... | 0 | 2024-07-13T07:04:11 | https://dev.to/kala12/the-future-of-meme-coin-development-company-1kbp | Inspired by Internet memes and jokes, cryptocurrency memes have gained immense popularity in recent years. As the world of digital currency evolves, meme-coins aren't just a fad—they're a phenomenon. Here's a look at the future of meme coin development and what it holds for developers and investors.
**Increased adoption and popularity
**Memecoins like Dogecoin and Shiba Inu have already gained significant attention. Their success showed that people are willing to invest in fun and community cryptocurrencies. As more people become aware and interested in cryptocurrencies, the adoption of meme coin is likely to increase as well.
**Community involvement and loyalty
**One of the driving forces behind meme-coins is strong community support. Developers should focus on interacting with their community to build loyalty and trust. This can include regular updates, an interactive social media presence and listening to community feedback.
**Real-World Use Cases
**To ensure long-term success, meme coin developers will likely focus on creating real-world use cases. This means integrating meme-coins into different platforms for payment, gifting or even gaming. Real utility helps native coins gain credibility and stability.
**Regulatory Overview
**As meme-coins become more popular, they will inevitably attract the attention of regulators. Developers must understand and follow the rules to avoid legal problems. Transparent practices and clear communication with investors can help navigate this difficult landscape.
**Technological Advances
**The technology behind memes continues to evolve. Developers are likely to explore new blockchain technologies and scalable solutions to make transactions faster and more secure. Innovations such as smart contracts and decentralized finance (DeFi) integrations also play a role.
**Collaborations and Partnerships
**In the future the development of meme-coins will involve more collaboration with established brands and companies. Partnerships can help achieve mainstream acceptance and create new opportunities for meme-coins. Joint ventures can also bring more expertise and resources.
**Enhanced Security
**Data security remains a top priority for cryptocurrency developers. As the number of cyber threats and hacking incidents increases, it is important to keep users' money and data safe. Strong security measures and regular audits help maintain investor confidence.
**Managing Market Volatility
**Memecoins are known for their volatility. Developers must find ways to manage and mitigate extreme price swings. This could include mechanisms such as liquid pools, staking or even linking the value of the coin to a stable asset to increase price stability.
**Environmental Aspects
**The environmental impact of cryptocurrencies, especially in relation to energy consumption, has become a major concern. Meme coin developers can focus on creating more energy efficient mining and transaction processes. One solution could be to use proof of stake (PoS) instead of proof of work (PoW).
**Education and Awareness

## Introduction
In the world of machine learning, the quality of your features can significantly impact the performance of your models. Feature engineering is the process of transforming raw data into meaningful features that better represent the underlying problem to the predictive models, leading to improved accuracy. In this article, we'll explore various techniques to enhance model performance through effective feature engineering.
### Understanding Feature Engineering
Feature engineering involves creating new features or modifying existing ones to improve the performance of machine learning models. It requires domain knowledge, creativity, and an understanding of the data. Effective feature engineering can lead to simpler models, better generalization, and improved interpretability.
### Techniques for Effective Feature Engineering
**Handling Missing Values**
How you handle missing values can significantly affect your model's performance.
**Imputation:** Replace missing values with mean, median, mode, or a constant value. Advanced techniques include using algorithms like k-nearest neighbors (KNN) or predictive models to estimate missing values.
**Removal:** If the number of missing values is small, you can remove the rows or columns with missing data.
**Encoding Categorical Variables**
Machine learning algorithms require numerical input, so categorical variables must be encoded.
**Label Encoding:** Assigns a unique integer to each category.
**One-Hot Encoding:** Creates binary columns for each category. Ideal for
nominal categorical variables where the order does not matter.
**Target Encoding:** Replaces each category with the mean of the target variable. Useful for high-cardinality features.
### Feature Scaling
Scaling features ensure that they are on the same scale, which can improve the performance of distance-based algorithms like KNN and gradient-based algorithms like logistic regression and neural networks.
**Standardization:** Results in features with a mean of 0 and a standard deviation of 1.
**Normalization:** Rescale features to a range of [0, 1] or [-1, 1]. Useful for algorithms like neural networks and KNN.
### Feature Creation
Creating new features from existing ones can capture additional information and improve model performance.
**Polynomial Features:** Create interaction terms and polynomial terms to capture non-linear relationships.
**Log Transformation:** Apply a logarithmic transformation to skewed features to reduce the impact of outliers and make the data more normally distributed.
**Binning:** Convert continuous features into categorical bins to capture non-linear relationships and reduce noise.
### Dimensionality Reduction
Reducing the number of features can help prevent overfitting and improve model interpretability.
**Principal Component Analysis (PCA):** Transforms features into a lower-dimensional space while retaining most of the variance.
**Linear Discriminant Analysis (LDA):** Reduces dimensionality by maximizing class separability.
### Feature Selection
Selecting the most relevant features can improve model performance and reduce computational complexity.
**Univariate Selection:** Select features based on statistical tests like chi-square for classification and ANOVA for regression.
**Recursive Feature Elimination (RFE):** Iteratively removes the least important features based on model performance.
Feature Importance: Use models like random forests or gradient boosting to rank features by their importance.
### Handling Imbalanced Data
Class imbalance can lead to biased models. Addressing this issue can significantly improve model performance.
**Resampling:** Oversample the minority class or undersample the majority class to balance the classes.
**Synthetic Data Generation:** Use techniques like Synthetic Minority Over-sampling Technique (SMOTE) to generate synthetic samples for the minority class.
**Class Weights:** Assign higher weights to the minority class during model training to balance the impact of each class.
### Time-Based Features
For time series data, creating time-based features can capture temporal patterns and improve model performance.
**Lag Features:** Create features based on previous time steps.
**Rolling Statistics:** Compute rolling mean, median, standard deviation, etc., to capture trends and seasonality.
**Date/Time Features:** Extract features like day of the week, month, hour, etc., to capture periodic patterns.
### Domain-Specific Features
Leverage domain knowledge to create features that capture important aspects of the problem. This can involve creating custom metrics, aggregating data, or engineering features specific to the domain.
Feature Interaction
Consider interactions between features to capture complex relationships. This can involve creating interaction terms, using decision trees to
identify important interactions, or apply techniques like feature crossing in deep learning.
### Practical Example
Let's illustrate feature engineering with a practical example.
**Handling Missing Values:** Impute missing values for square footage with the mean and for neighborhood with the mode.
**Encoding Categorical Variables:** One-hot encode the neighborhood feature.
**Feature Scaling: **Standardize square footage and the number of bedrooms.
**Feature Creation: **Create a new feature, price per square foot, by dividing the price by the square footage.
**Feature Selection:** Use feature importance from a random forest model to select the most relevant features.
**Handling Imbalanced Data:** If predicting whether a house price is above a certain threshold, balance the classes using SMOTE.
By applying these techniques, we can create a more robust model that better captures the underlying patterns in the data.
### Conclusion
Effective feature engineering is a critical step in the machine learning pipeline. By handling missing values, encoding categorical variables, scaling features, creating new features, reducing dimensionality, selecting relevant features, addressing class imbalance, leveraging time-based features, incorporating domain-specific knowledge, and considering feature interactions, you can significantly enhance model performance. Experimentation and domain expertise, particularly in a [Data Science course in Lucknow](https://uncodemy.com/course/data-science-training-course-in-lucknow), Nagpur, Delhi, Noida, and all locations in India, are key to identifying the most impactful features for your specific problem.

Each week Mohammad S. Anwar sends out [The Weekly Challenge](https://theweeklychallenge.org/), a chance for all of us to come up with solutions to two weekly tasks. My solutions are written in Python first, and then converted to Perl. It's a great way for us all to practice some coding.
[Challenge](https://theweeklychallenge.org/blog/perl-weekly-challenge-277/), [My solutions](https://github.com/manwar/perlweeklychallenge-club/tree/master/challenge-277/sgreen)
## Task 1: Count Common
### Task
You are given two array of strings, `@words1` and `@words2`.
Write a script to return the count of words that appears in both arrays exactly once.
### My solution
In my day job, I usually don't use TDD for writing new code. Things are different when I work on The Weekly Challenge, as there are examples that can be used to test success. Once I've pull the code into my local repo and before I write any code, I create `test.py` with the expected output. I then do my code, and ensure the tests past. And occasionally I find out my code doesn't pass the tests. Today was such an example.
My original solution for this was to convert the lists into sets and perform an intersection of them. Simple one liner. However the third test failed because the words 'is' appears more than once.
In the end I took a different approach. I take each word for from first list and check that it appears once (and only once) in all the lists. While that task takes two arrays of strings, my solution will take many.
```python
def count_common(*words_list: list[list]) -> int:
count = 0
for word in set(words_list[0]):
for words in words_list:
if words.count(word) != 1:
break
else:
count+=1
return count
```
The only funky thing here (from a Perl perspective) is the `for ... else` feature. In Python, the else part is only executed when the loop is not broken out of.
For the command line input a take a strings of space-separated values to make each list.
### Examples
```bash
$ ./ch-1.py "Perl is my friend" "Perl and Raku are friend"
2
$ ./ch-1.py "Perl and Python are very similar" "Python is top in guest languages"
1
$ ./ch-1.py "Perl is imperative Lisp is functional" "Crystal is similar to Ruby"
```
## Task 2: Strong Pair
### Task
You are given an array of integers, `@ints`.
Write a script to return the count of all strong pairs in the given array. A pair of integers x and y is called strong pair if it satisfies: `0 < |x - y| < min(x, y)`.
### My solution
This doesn't need much explanation, I simply loop through the unique positions, and count the number of times the condition is met.
```python
def strong_pair(ints: list) -> int:
ints = list(set(ints))
count = 0
for i in range(len(ints)-1):
for j in range(i+1, len(ints)):
if abs(ints[i]-ints[j]) < min(ints[i], ints[j]):
count += 1
return count
```
### Examples
```bash
$ ./ch-2.py 1 2 3 4 5
4
$ ./ch-2.py 5 7 1 7
1
```

**Apa Itu Buasir**
Buasir, atau hemoroid, merupakan masalah kesihatan yang melibatkan pembesaran dan bengkaknya pembuluh darah di sekitar dubur. Keadaan ini boleh menjadi tidak selesa dan menyakitkan, dan biasanya disebabkan oleh tekanan yang berlebihan pada saluran pembuangan atau pembuluh darah di dalam rektum dan dubur.
**Punca Buasir**
Buasir boleh disebabkan oleh beberapa faktor, termasuk:
Tekanan Berlebihan: Tekanan semasa sembelit atau ketegangan semasa mengandung.
Faktor Genetik: Memiliki keluarga dengan riwayat buasir meningkatkan risiko.
Gaya Hidup dan Diet: Kekurangan serat dalam makanan, kurangnya aktiviti fizikal, dan kebiasaan duduk terlalu lama.
**Jenis Buasir**
Terdapat dua jenis utama buasir:
Buasir Dalaman: Terletak di dalam rektum dan biasanya tidak dapat dilihat atau dirasai kecuali apabila ia prolaps (keluar melalui dubur).
Buasir Luaran: Terletak di luar dubur dan boleh terasa sebagai benjolan yang lembut.
**Gejala Buasir****
Gejala buasir bergantung kepada jenis dan tahap keparahannya. Gejala yang biasa termasuk
Rasa gatal atau terbakar di sekitar dubur.
Rasa tidak selesa atau sakit semasa duduk.
Perdarahan semasa atau selepas buang air besar.
Benjolan atau pembengkakan di sekitar dubur.
**Rawatan dan Pencegahan**
Rawatan bergantung kepada tahap dan keparahan buasir:
Pengubatan Konservatif: Termasuk penggunaan krim atau salep, dan mengubah gaya hidup untuk mengelakkan sembelit.
Prosedur Minimally Invasive: Seperti pengikatan kawat atau skleroterapi untuk buasir yang teruk.
Pembedahan: Kadang-kadang diperlukan untuk buasir yang sangat teruk atau kronik


**Pencegahan Buasir**
Langkah-langkah berikut boleh membantu mengurangkan risiko atau mencegah kekambuhan buasir:
Makan makanan kaya serat untuk mengelakkan sembelit.
Minum banyak air untuk menjaga konsistensi najis.
Berolahraga secara teratur.
Elakkan menahan nafas semasa membuang air besar.







Buasir adalah masalah umum yang boleh mempengaruhi kualiti hidup seseorang. Dengan mengenal pasti gejala awal dan mengambil langkah-langkah pencegahan yang sesuai, kebanyakan orang dapat mengelakkan keparahan yang lebih teruk. Bagi sesiapa yang mengalami gejala buasir yang serius atau berterusan, adalah penting untuk mendapatkan nasihat dan rawatan dari profesional kesihatan untuk mengelakkan komplikasi yang lebih serius.

1,922,019 | Adding Internationalization (i18n) to Next.js Apps: Supporting Multiple Languages | Internationalisation, abbreviated as i18n, is a critical component of contemporary web development.... | 0 | 2024-07-13T07:26:50 | https://www.swhabitation.com/blogs/adding-internationalization-i18n-to-nextjs-apps-supporting-multiple-languages | internationalization, nextjs, i18n, webdev | Internationalisation, abbreviated as i18n, is a critical component of contemporary web development. To put it another way, i18n means preparing your app to be able to support multiple languages, making sure that your content can be accessed by users from around the world. By adding i18n to your Next.js app, you are opening up the opportunity for user’s who speak different languages to enjoy your app, and reach a wider audience. This guide is a walkthrough of the steps to add i18n to your Next.js app in a frictionless way, including lots of code examples to aid along the way.
## Setting Up Next.Js For I18n
Firstly, let us confirm that Next.js has been installed. If you haven't already, get started with a new Next.js project by executing the following commands:
```
npx create-next-app my-i18n-app
cd my-i18n-app
```
Next, we need to configure our Next.js to support i18n. Open your project's `next.config.js` file and add the following configuration:
```
// next.config.js
module.exports = {
i18n: {
locales: ['en', 'fr', 'es'], // List all the languages you want to support
defaultLocale: 'en', // Default language
},
};
```
Once again, we must configure our Next.js application to be able to use i18n. This involves opening our `next.config.js` file, and adding the following configuration:
## Creating Language Files
Language files are the container for your translations. For this we will be using JSON files. Create a locales directory at the root of your project, with a sub-directory for each language that your want support. For example:
```
/locales
/en
common.json
/fr
common.json
/es
common.json
```
Every JSON will have key-value pairs for your translations. Here is an example of what `common.json` might look like for English (`/locales/en/common.json`):
```
{
"welcome": "Welcome to our website!",
"description": "This is an example of internationalization with Next.js."
}
```
And for French (`/locales/fr/common.json`):
```
{
"welcome": "Bienvenue sur notre site!",
"description": "Ceci est un exemple d'internationalisation avec Next.js."
}
```
## Adding A Language Switcher
To enable users to switch languages, we will create a basic language switcher component- Create a new file called `LanguageSwitcher.js` in your `components` folder:
```
// components/LanguageSwitcher.js
import { useRouter } from 'next/router';
const LanguageSwitcher = () => {
const router = useRouter();
const changeLanguage = (locale) => {
router.push(router.pathname, router.asPath, { locale });
};
return (
<div>
<button onClick={() => changeLanguage('en')}>English</button>
<button onClick={() => changeLanguage('fr')}>Français</button>
<button onClick={() => changeLanguage('es')}>Español</button>
</div>
);
};
export default LanguageSwitcher;
```
You can then add this component to your pages to enable the user to swap languages.
## Translating Pages And Components
To assist with translations, Next.js offers a `useTranslation` hook through the `next-i18next` library. To get started:
```
npm install next-i18next
```
Then, create a `next-i18next.config.js` file in the root of your project:
```
// next-i18next.config.js
module.exports = {
i18n: {
defaultLocale: 'en',
locales: ['en', 'fr', 'es'],
},
};
```
Change your `next.config.js` to use this setup:
```
// next.config.js
const { i18n } = require('./next-i18next.config');
module.exports = {
i18n,
};
```
To finish up, cover your app with the `appWithTranslation` higher-order component. Make changes to `pages/_app.js`:
```
// pages/_app.js
import { appWithTranslation } from 'next-i18next';
import '../styles/globals.css';
function MyApp({ Component, pageProps }) {
return <Component {...pageProps} />;
}
export default appWithTranslation(MyApp);
```
To apply translations in your components or pages, you need to import the `useTranslation` hook:
```
// pages/index.js
import { useTranslation } from 'next-i18next';
import { serverSideTranslations } from 'next-i18next/serverSideTranslations';
import LanguageSwitcher from '../components/LanguageSwitcher';
export async function getStaticProps({ locale }) {
return {
props: {
...(await serverSideTranslations(locale, ['common'])),
},
};
}
export default function Home() {
const { t } = useTranslation('common');
return (
<div>
<LanguageSwitcher />
<h1>{t('welcome')}</h1>
<p>{t('description')}</p>
</div>
);
}
```
## Managing Dates, Numbers, And Other Locale-Specific Data
Translating text is significant part of internationalization. There are other aspects to consider. Dates. Numbers. Currencies. Let's look at how to handle these.
## Formatting Dates And Times
To format dates and times according to user's locale You can use the `Intl.DateTimeFormat` API. Here is an example
```
const formatDate = (date, locale) => {
return new Intl.DateTimeFormat(locale, {
year: 'numeric',
month: 'long',
day: 'numeric',
}).format(date);
};
// Usage
const date = new Date();
console.log(formatDate(date, 'en')); // July 13, 2024
console.log(formatDate(date, 'fr')); // 13 juillet 2024
```
## Handling Numbers And Currencies
For formatting numbers and currencies the `Intl.NumberFormat` API is very useful. Here is how you can use it,
```
const formatNumber = (number, locale, currency) => {
return new Intl.NumberFormat(locale, {
style: 'currency',
currency: currency,
}).format(number);
};
// Usage
const amount = 123456.789;
console.log(formatNumber(amount, 'en-US', 'USD')); // $123,456.79
console.log(formatNumber(amount, 'fr-FR', 'EUR')); // 123 456,79 €
```
By using these internationalization APIs, you ensure that dates, numbers, and currencies are displayed correctly based on the user's locale.
## Testing Your I18n Setup
To see your translations in action, run your Next.js app:
```
npm run dev
```
Open your browser and navigate to your app. You should see the text in your default language. Try switching languages using the language switcher to see the translated text.
## Conclusion
By this point, you have walked through adding internationalization to your Next.js application. We looked at how to set up Next.js for I18n, create language files, add a language switcher, translate your pages and components, and manage locale-specific data such as dates and numbers.

1,922,023 | Connecting a Serverless PostgreSQL Database (Neon) to NestJS Using the Config Service | Introduction The primary goal of this project is to illustrate the process of connecting a... | 0 | 2024-07-13T13:43:27 | https://dev.to/jardiin/connecting-a-serverless-postgresql-database-neon-to-nestjs-using-the-config-service-221l | nestjs, postgressql, typeorm, neonpostgressql | ### Introduction
The primary goal of this project is to illustrate the process of connecting a Neon database to a NestJS application through the Config Service, which helps manage configuration settings in a clean and organized manner. Neon PostgreSQL is designed to deliver a seamless database experience without the hassle of managing infrastructure.
In addition, I will demonstrate (in another guide) how to implement create and manage database entities with TypeORM, a popular Object-Relational Mapping (ORM) tool, to define and manage database entities.
### Prerequisites
1. A NestJS and TypeScript project already initialized -> If you don't have a NestJS project set up yet, you can follow the official NestJS guide to initialize a new project with TypeScript. ([Link](https://docs.nestjs.com/first-steps))
2. An account on Neon PostgreSQL -> You can sign up for a Neon PostgreSQL account ([Link](https://neon.tech/))
3. For setting up a new project in Neon PostgreSQL, you can follow their official guide ([official link](https://neon.tech/docs/get-started-with-neon/signing-up#step-2-onboarding-in-the-neon-console)). As of now, Neon PostgreSQL offers advantageous free solutions when setting up a new project
### Packages
In addition to the packages provided by Nest on the initial setup, the following dependencies will help us to connect to Neon database.
```json
"dependencies": {
"@nestjs/common": "^10.0.0",
"@nestjs/config": "^3.2.2",
"@nestjs/core": "^10.0.0",
"@nestjs/platform-express": "^10.3.10",
"@nestjs/typeorm": "^10.0.2",
"class-transformer": "^0.5.1",
"class-validator": "^0.14.1",
"dotenv": "^16.4.5",
"express": "^4.19.2",
"pg": "^8.12.0",
"typeorm": "^0.3.20",
}
```
### Configuring Environment Variables
Create a .env file in the root directory of your NestJS project. This file will contain all the necessary environment variables for your application. Below there is an example of a ".env" file for our project
```env
# ====== NEON POSTGRES ====== #
DATABASE_HOST='NEON PGHOST'
DATABASE_USER='NEON PGUSER'
DATABASE_PASSWORD='NEON PGPASSWORD'
DATABASE_PORT= 5432 #(usually it's 5432)
DATABASE_ENDPOINT_ID='NEON ENDPOINT_ID'
DATABASE_NAME='NEON PGDATABASE'
# ====== PORTS ====== #
NEST_PORT= YOUR_NEST_PORT #(usually it's 3000)
```
Given that the **prerequisite** N°3 has been met and you have successfully created a project on Neon PostgreSQL, you will find the necessary environment variables directly from the Neon dashboard. Here is an image illustrating the relevant variables you will need to configure

### (1) Configuring the Nest.JS Project -> config/ folder
We'll start by organizing our configuration files in the config folder. Here, we'll create two essential files: `app.config.ts` and `database.config.ts`
#### app.config.ts
This setup register the application configuration settings under the name 'config' with @nestjs/config. Here we will define the port and node environment.
```typescript
import { registerAs } from '@nestjs/config';
export default registerAs('config', () => ({
port: parseInt(process.env.NEST_PORT, 10) || 5575,
nodenv: process.env.NODE_ENV,
}));
```
#### database.config.ts
This setup configures the connection options for Neon PostgreSQL database connections using the environment variables defined earlier. It utilizes `@nestjs/config` to manage environment variables
```typescript
import { registerAs } from '@nestjs/config';
export default registerAs('database', () => ({
type: 'postgres', // Neon PostgreSQL database type
host: process.env.DATABASE_HOST || 'localhost',
database: process.env.DATABASE_NAME,
port: process.env.DATABASE_PORT,
username: process.env.DATABASE_USER,
password: process.env.DATABASE_PASSWORD,
entities: [`${__dirname}/../**/*.entity{.ts,.js}`], // TypeORM Entities to be stored in the database
subscribers: [`${__dirname}/../**/*.subscriber{.ts,.js}`], // OPTIONAL
synchronize: process.env.NODE_ENV === 'development', // Set `true` to synchronize the database schema with the entities
logging: process.env.NODE_ENV === 'development',
ssl: true,
connection: {
options: `project=${process.env.DATABASE_ENDPOINT_ID}`,
},
migrations: [`${__dirname}/../database/migrations/*{.ts,.js}`], // Migrations
migrationsTableName: 'typeorm-migrations', // Set the name of the migrations table
}))
```
#### index.ts
This index.ts file simplifies exporting configurations by re-exporting `AppConfig` and `DatabaseConfig` from their respective files
```typescript
export { default as AppConfig } from './app.config';
export { default as DatabaseConfig } from './database.config';
```
### (2) Configuring the Nest.JS Project -> database/ folder
Inside this folder we configure a TypeORM DataSource for Neon database using settings from environment variables.
#### typeorm.config.ts
```typescript
// ====== IMPORTS =========
import { DataSource } from 'typeorm';
import { ConfigService } from '@nestjs/config';
import { config } from 'dotenv';
config();
// 1. Define a configuration for TypeORM
const configService = new ConfigService();
export default new DataSource({
type: 'postgres', // Neon PostgreSQL database type
host: configService.get<string>('DATABASE_HOST'),
database: configService.get<string>('DATABASE_NAME'),
port: configService.get<number>('DATABASE_PORT'),
username: configService.get<string>('DATABASE_USER'),
password: configService.get<string>('DATABASE_PASSWORD'),
entities: [`${__dirname}/../src/**/*.entity{.ts,.js}`],
subscribers: [`${__dirname}/../**/*.subscriber{.ts,.js}`] // OPTIONAL,
synchronize: process.env.NODE_ENV === 'development',
logging: process.env.NODE_ENV === 'development',
ssl: true,
migrations: [`${__dirname}/../database/migrations/*{.ts,.js}`],
migrationsTableName: 'typeorm-migrations', // Set the same name as you did on database.config
})
```
From now on, this file will manage the entities you create in your project. Additionally, if you need to make modifications to the database schema, the setup includes support for using migrations.
### (3) Configuring the Nest.JS Project -> app.module.ts
The `app.module.ts` orchestrates the main structure and dependencies of the NestJS application. It imports the necessary modules to configures TypeORM for database access using environment variables.
```typescript
// ======== MODULES =========
import { Module, forwardRef } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';
import { ConfigModule, ConfigService } from '@nestjs/config';
// ======== CONTROLLERS =========
import { AppController } from './app.controller';
// ======== SERVICES =========
import { AppService } from './app.service';
// ======== CONFIG =========
import { AppConfig, DatabaseConfig } from 'config/index';
@Module({
imports: [
// Load environment variables
ConfigModule.forRoot({
isGlobal: true, // Set `true` for global configuration
cache: true,
load: [AppConfig, DatabaseConfig],
}),
// TypeORM configuration
TypeOrmModule.forRootAsync({
imports: [ConfigModule], // Import the ConfigModule
useFactory: (configService: ConfigService) => ({
...configService.get('database'),
}),
inject: [ConfigService], // Inject the ConfigService
}),
// Other Project Modules
],
controllers: [AppController],
providers: [AppService],
})
export class AppModule { }
```
### (4) Configuring the Nest.JS Project -> main.ts
This `main.ts` file initializes the NestJS application, sets up middleware, establishes a database connection using configuration from ConfigService, and starts the server to handle incoming requests.
```typescript
// ====== IMPORTS ======
import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import * as dotenv from 'dotenv';
import { static as expose } from 'express';
import { ConfigService } from '@nestjs/config';
dotenv.config();
async function bootstrap() {
const app = await NestFactory.create(AppModule);
// Configuration Service
const configService = app.get(ConfigService);
const port = configService.get('NEST_PORT');
await app
.listen(port || 3375)
.then(() => {
console.log('Current Database Name: ', configService.get('DATABASE_NAME'));
console.log(`Application is running on port`, configService.get('NEST_PORT'));
})
.catch((err) => {
console.error('Error while starting application: ', err.message);
});
}
bootstrap();
```
### Conclusion
The configuration steps are now complete. To start the application and connect to the configured database, simply run the following command:
```bash
yarn start:dev OR yarn start
```
You should see the database connection details in the terminal, indicating that the connection has been successfully established like the picture below

1,922,025 | Understanding SQL Joins and Grouping using Set Theory | 🏁 In the world of databases, SQL joins are fundamental operations that allow us to combine data from... | 0 | 2024-07-13T10:13:12 | https://dev.to/samandar_komilov/understanding-sql-joins-and-grouping-using-set-theory-i58 | sql, database | 🏁 In the world of databases, SQL joins are fundamental operations that allow us to combine data from multiple tables based on related columns. While SQL joins might seem daunting at first, they are conceptually rooted in Set Theory — a branch of mathematics that deals with collections of objects and operations on them.

This post aims to demystify SQL joins by exploring their relationship with set theory concepts:
1. **Understanding Tables as Sets:** In SQL, each table can be seen as a set of rows (records). Just as in set theory, these rows are unique unless explicitly defined otherwise.
2. **Types of Joins:** SQL offers several types of joins—such as inner joins, left joins, right joins, and outer joins—each serving a specific purpose in combining data from multiple tables.
3. **Set Operations Analogies:** We'll delve into how SQL joins correspond to set operations. For instance, an inner join can be likened to the intersection of two sets, where only the common elements (rows) are retained.
4. **Visualizing Joins:** Using practical examples and diagrams, we'll visualize how data from different tables intersects or combines based on join conditions.
By the end of this post, you'll have a clearer understanding of SQL joins not just as technical database operations, but as logical extensions of set theory principles.
## Understanding Tables as Sets
Each table consists of some number of rows and columns, we know. In each row, there are a number of elements equal to the number of columns.

For instance, in this table, there are 4 rows with 3 elements each (3 columns). Each row is considered as a **tuple** in set theory and the table is a **set of tuples** of elements:
`K = {(1, Polat, 45), (2, Memati, 40), (3, Abdulhey, 39), (4, Cahit, 35)}`
So, I hope we got the point. Now, let's move onto the JOINS.
## Types of Joins
There are various sources that tell distinct information about the exact number of Joins. We'll consider the following Join types:
1. INNER JOIN
2. LEFT (OUTER) JOIN
3. RIGHT (OUTER) JOIN
4. FULL (OUTER) JOIN
5. CROSS JOIN (Cartesian Product)
6. ANTI LEFT JOIN
7. ANTI RIGHT JOIN
8. ANTI OUTER JOIN
## INNER JOIN
An inner join returns only the rows (tuples) that have matching values in both tables (sets).

In set theory terms, it performs an **intersection** of two sets. Let's say, we are inner joining A and B tables, then:
```
Inner Join = A ∩ B
```
It would be clearer if we consider elementwise, yeah? So, say we have these sets:
```
A = {(1, 'Pusat'), (2, 'Zaza'), (3, 'Murad')}
B = {(1, 'HR'), (2, 'IT'), (4, 'Sales')}
```
Then the inner join on the 1st element (employeeID) of these 2 sets will be:
```
A ∩ B = {(1, 'Pusat', 'HR'), (2, 'Zaza', 'IT')}
```
But `'Murad'` and `'Sales'` have different IDs, so they are not present in inner join result.
## LEFT (OUTER) JOIN
A left outer join returns all the rows from the left table (set), along with the matching rows from the right table (set). If there is no match, the result is NULL from the right table.

In set theory, it can be thought of as including all elements from the left set and the intersection with the right set:
```
Left Outer Join = A ∪ (A ∩ B)
```
In terms of the above example sets, the resulting left outer join set will be like this:
```
A ∪ (A ∩ B) = {(1, 'Pusat', 'HR'), (2, 'Zaza', 'IT'), (3, 'Murad', NULL)}
```
Because, the result is all the matching rows (tuples) plus the other tuples on the left set. Due to the absence of Department for `Murad`, `NULL` will be saved.
## RIGHT (OUTER) JOIN
A right outer join returns all the rows from the right table (set), along with the matching rows from the left table (set). If there is no match, the result is NULL from the left table. This is similar to the left join but includes all elements from the right set.

In set theory, it can be thought of as including all elements from the right set and the intersection with the left set:
```
Right Outer Join = B ∪ (A ∩ B)
```
In terms of the above example sets, the resulting right outer join set will be like this:
```
B ∪ (A ∩ B) = {(1, 'Pusat', 'HR'), (2, 'Zaza', 'IT'), (4, NULL, 'Sales')}
```
Because, the result is all the matching rows (tuples) plus the other tuples on the right set. Due to the absence of Name for `Sales`, `NULL` will be saved.
## FULL (OUTER) JOIN
A full outer join returns all the rows when there is a match in either table (set). If there is no match, the result is NULL on the side that does not have a match.

In set theory, it is the **union** of both sets, including their intersection:
```
Full Outer Join = (A ∪ B) ∪ (A ∩ B)
```
In terms of the above example sets, the resulting right outer join set will be like this:
```
B ∪ (A ∩ B) = {(1, 'Pusat', 'HR'), (2, 'Zaza', 'IT'), (3, 'Murad', NULL), (4, NULL, 'Sales')}
```
This is like the sum of 2 above cases, but the matching rows participate only once in the result set.
## CROSS JOIN (Cartesian Product)
A cross join produces the Cartesian product of two tables, meaning it combines each row from the first table with every row from the second table.

In set theory, there is a cartesian product operation: `A × B`.
In terms of the above example sets, the result becomes:
```
A × B = {(1, 'Pusat', 1, 'HR'), (1, 'Pusat', 2, 'IT'), ...}
```
The list is too long (3×3 elements), hence I left only a few of them, but you got the point.
## ANTI LEFT JOIN
Returns rows from the left table (A) that do not have matching rows in the right table (B).

In set theory, this operation is similar to finding elements in set A that are not in set B, denoted as `A ∖ B`. The result according to the example sets above:
```
A ∖ B = {(3, 'Murad')}
```
## ANTI RIGHT JOIN
Returns rows from the right table (B) that do not have matching rows in the left table (A).

In set theory, this operation is similar to finding elements in set B that are not in set A, denoted as `B ∖ A`. The result according to the example sets above:
```
B \ A = {(4, 'Sales')}
```
## ANTI FULL JOIN
Returns rows that do not have matching rows in either table (A or B).

In set theory, this operation corresponds to the symmetric difference of sets A and B, denoted as `A Δ B`. The result according to the example sets above:
```
A Δ B = {(3, 'Murad', NULL), (4, NULL, 'Sales')}
```
Enough with Joins, now let's start considering Group By in terms of set theory and with examples.
## GROUP BY

When you get a soft starter, you are providing the heavy-duty motor with assistance to start up its electric thrashing in an orderly manner. Voltage increases slowly to keep the motor protected over time. How Soft Starters Work & Why They Matter
Advantages of Soft Starters
If you just want to reduce the inrush surge of current when a motor is started soft starters are fine. This surge can damage the engine and other machinery. Soft starters also help reduce the wear and tear on a motor by achieving gentle start-up.
Soft starters have a number of advantages that make them wise investments for any heavy-duty motor system. A major Fan Frequency Inverter advantage is that they can reduce a sudden surge of electrical current when motor starts. A substantial spike in current when it is initially energized, referred to as Inrush Current, can be harmful for both the motor and associated equipment. Through a controlled increase in voltage, this problem is avoided by soft starters which helps to extend the life of the motor.
Further, these devices are vital as motor starters and contribute immensely towards the reduction of mechanical stress caused to the Motor during startup. Soft starters do not subject a motor to sudden and harsh activation - they initiate slow, gentle startups instead of jerking into motion, which helps reduce internal wear on key components (which contributes toward the longevity of the unit).
Using Soft Starters
All you need to do is to place it in between the power source and your motor. This allows the settings to be based on what that motor needs. There is a manual that comes with the soft starter which gives you instructions on how to set it up.
Soft starters are easy and very user friendly to use. Start interconnecting the soft starter in between the motor and power supply. Then adjust the settings for the motor as required. The accompanying manual offers specific procedures for soft starter configuration; clear and detailed instructions make setup simple!
Applications of Soft Starters
Soft starter used in marine, oil and gas,mining,water treatment industry. In these industries, they are used to prime machines such as pumps, fans or conveyor belts.
Soft starters are widely used across marine, oil and gas, mining as well as the water treatment industries. Major appliances when them include Fan Inverter pumps, fans and conveyor belts soft starters are widely used to initiate these domains. These characteristics of adaptive functionality and reliability makes it a key element in enabling the seamless operation within these industrial settings.
Conclusion
Their use in heavy-duty motors cannot be completed without the very existence of soft starters. They make for easy starting and longevity of motors. The Fan Frequeny Converter quality of soft starter & Manufacturer are key to safe and efficient operations.
To sum up, soft starters are indispensable in ensuring that the start-up of a heavy motor occurs smoothly. They work to provide motors with long-term service life by promoting smooth and controlled starts. It is necessary to choose a well-functioning soft starter made by experienced manufacturer for both safety and efficiency in motor systems. | hdjfb_hsdhd_ef70dd1f48779 |

1,922,036 | New Css Media Query Syntax(Media Query Level 4 or MQ4) | The new CSS media query syntax, often referred to as "Media Query Level 4" or "MQ4", introduces... | 0 | 2024-07-13T07:58:07 | https://dev.to/e-tech/new-css-media-query-syntaxmedia-query-level-4-or-mq4-2ha3 | The new CSS media query syntax, often referred to as "Media Query Level 4" or "MQ4", introduces several improvements and new features. Here are the key aspects of the new syntax:
1.**Range Syntax:**
Instead of using min-width and max-width, you can now use a more concise range syntax:
@media (width >= 768px) and (width <= 1024px) {
/* Styles for screens between 768px and 1024px */
}
**2.Comparison Operators:**
You can use <, >, <=, >= for more intuitive comparisons:
@media (width > 1200px) {
/* Styles for screens wider than 1200px */
}
**3.'not' Keyword:**
The 'not' keyword can be used for inverse conditions:
@media not (color) {
/* Styles for non-color devices */
}
**4.Custom Media Queries:**
You can define reusable media query aliases:
@custom-media --small-viewport (width <= 30em);
@media (--small-viewport) {
/* Styles for small viewports */
}
**5.Media Query Ranges:**
You can use the 'to' keyword for ranges:
@media (400px <= width <= 700px) {
/* Equivalent to the above */
}
**6.Improved Logical Operators:**
'and', 'or', and 'not' can be used more flexibly:
@media ((hover: hover) and (pointer: fine)) or (width > 1200px) {
/* Styles for devices with hover and fine pointer, or large screens */
}
**7.Feature Detection:**
New features for detecting device capabilities:
@media (hover: hover) {
/* Styles for devices that support hover */
}
**8.Aspect Ratio:
Easier syntax for targeting aspect ratios:**
@media (aspect-ratio: 16/9) {
/* Styles for 16:9 aspect ratio */
}
It's important to note that while these features are part of the CSS Media Queries Level 4 specification, browser support may vary. Always check the current browser support before using these features in production. For wider compatibility, you might need to provide fallbacks or use a preprocessor that compiles to the older syntax for browsers that don't yet support the new features. | e-tech | |

Serolean's distinct mechanism that makes it work lies in its ability to naturally boost serotonin levels, a neurotransmitter pivotal in regulating appetite and mood. Elevated serotonin levels can lead to reduced appetite, curbing unnecessary cravings and overeating, which is a primary factor in weight gain. By addressing the root cause of weight challenges at the neurotransmitter level, Serolean offers a unique approach compared to conventional weight management supplements.

1,922,034 | Buy Now, Pay Later (BNPL) - How It Works, Benefits and Design | Buy Now, Pay Later (BNPL) is a form of digital lending. BNPL services offer customers a way to... | 0 | 2024-07-13T07:55:37 | https://dev.to/seyhunak/buy-now-pay-later-bnpl-how-it-works-benefits-and-design-19h5 | Buy Now, Pay Later (BNPL) is a form of digital lending. BNPL services offer customers a way to finance their purchases by splitting the cost into smaller, manageable installments, typically without requiring an upfront payment. This digital lending model involves assessing the customer’s creditworthiness, approving the loan, and managing repayments, all through online or mobile platforms. BNPL leverages digital technology to provide a seamless and convenient borrowing experience, making it a subset of the broader digital lending ecosystem.
Buy Now, Pay Later (BNPL in short) services provide a convenient payment option for customers, allowing them to make purchases and pay for them over time.
Here’s a detailed breakdown of how BNPL works, I like to explain in step by step both in business and technical perspective.
Journey
1. Customer Makes a Purchase
The process begins when a customer selects items they want to purchase and proceeds to the checkout on a merchant’s website or physical store. At the checkout stage, the merchant offers BNPL as one of the payment options. The customer then selects the BNPL option to split the cost into manageable installments.
2. Customer Signs Up or Signs In
Once the BNPL option is selected, the customer is prompted to sign up for the BNPL service if they don’t already have an account, or to sign in if they do. Signing up involves providing personal information and agreeing to the terms and conditions of the service. This step ensures that the service provider has the necessary details to perform credit and identity checks.
3. Instant e-KYC and Credit Risk Analysis
To ensure the customer’s eligibility, the BNPL service provider performs an instant electronic Know Your Customer (e-KYC) verification and credit risk assessment. This involves checking the customer’s identity and evaluating their creditworthiness based on various data points, including credit history and financial behavior. This step is crucial for minimizing the risk of defaults.
4. Approval and Payment
Based on the results of the e-KYC and credit risk analysis, the BNPL service provider decides whether to approve the transaction. If approved, the BNPL provider pays the merchant on behalf of the customer, allowing the customer to complete the purchase without paying the full amount upfront. This immediate payment to the merchant helps ensure a smooth transaction and quick delivery of goods.
5. Product Delivery
With the payment process completed, the merchant proceeds to ship the product to the customer. The customer receives the product just as they would if they had paid in full at the time of purchase. This seamless experience enhances customer satisfaction and encourages repeat business.
6. Repayment Schedule
After the purchase, the customer is provided with a repayment schedule outlining the installment amounts and due dates. The repayment period and frequency of installments can vary depending on the terms set by the BNPL provider. This schedule helps customers manage their finances by spreading the cost over time.
7. Customer Makes Repayments
The final step involves the customer making payments according to the provided schedule. Payments can be automatically deducted from the customer’s bank account or made manually through the BNPL platform. These installments are usually interest-free if paid on time, though late payments may incur additional fees.
Key Players and Their Roles
The key players in the BNPL ecosystem include the customer, the merchant, and the BNPL service provider. The customer benefits from flexible payment options, allowing them to manage their finances better. The merchant benefits from increased sales and reduced cart abandonment rates, as BNPL options can attract a wider range of customers. The BNPL service provider facilitates the transaction, pays the merchant upfront, and manages the repayment process, generating revenue through interest, late fees, and merchant fees.
Benefits of BNPL
For customers, BNPL services provide financial flexibility, enabling them to acquire products without paying the full price upfront. This can be particularly useful for budgeting and managing high-value purchases. For merchants, offering BNPL can lead to higher conversion rates and average order values, making it an attractive option to increase sales. Lastly, BNPL providers benefit from building a customer base and generating revenue through various fees.
This detailed explanation highlights how BNPL services work, detailing each step of the process and the roles of the key players involved, providing a comprehensive understanding of the BNPL ecosystem.
The provided diagram titled “How Does Buy Now Pay Later Work?” outlines the sequential steps involved in a Buy Now Pay Later (BNPL) process.
Now lets find out, with simple explanation of each step in the diagram:
Customer makes an online purchase at a merchant site: The process begins with a customer selecting products and making an online purchase on a merchant’s website.
Merchant offers BNPL as a payment option at checkout: At the checkout stage, the merchant provides the customer with the option to choose BNPL as a payment method.
Customer signs up/signs in to the BNPL service providing platform: The customer either signs up for a new account or signs in to an existing account on the BNPL service provider’s platform.
Payment is debited from the BNPL platform: Once the BNPL option is selected and approved, the payment for the purchase is debited from the BNPL platform. This means the BNPL provider pays the merchant on behalf of the customer.
Product is delivered to the customer: The merchant processes the order and delivers the product to the customer.
Instant e-KYC and credit risk analysis is done by the BNPL service provider: The BNPL service provider performs an electronic Know Your Customer (e-KYC) process and conducts a credit risk analysis to assess the customer’s creditworthiness.
BNPL service provider approves the credit: Based on the results of the e-KYC and credit risk analysis, the BNPL service provider decides whether to approve the credit. If approved, the customer can proceed with the BNPL payment plan.
Customer pays the balance to the BNPL service provider at the end of credit period: The final step involves the customer repaying the BNPL service provider. The customer pays the outstanding balance as per the agreed credit terms at the end of the credit period.
Business Use-Cases for Buy Now, Pay Later (BNPL) Systems
Buy Now, Pay Later (BNPL) systems offer versatile financing solutions across various industries, enhancing customer satisfaction and driving sales.
In e-commerce platforms, BNPL increases conversion rates and average order values by providing flexible payment options. Retail stores can enhance customer loyalty and attract budget-conscious shoppers by offering BNPL at the point of sale.
The travel and hospitality sector benefits from increased bookings and revenue by making travel more accessible through installment payments.
Healthcare services can improve access and manage cash flow by allowing patients to finance medical procedures. Educational institutions can boost enrollment and retention by enabling students to pay tuition fees in installments.

1,922,035 | Creating a CSS Dark/Light Mode Toggle | Dark and light mode switchers have become increasingly popular, offering users the flexibility to... | 0 | 2024-07-13T07:57:11 | https://dev.to/mdhassanpatwary/creating-a-css-darklight-mode-switcher-26cd | webdev, html, css, javascript | Dark and light mode switchers have become increasingly popular, offering users the flexibility to choose their preferred visual experience. Whether it's to reduce eye strain, save battery life, or simply follow personal preference, implementing a dark/light mode switcher can significantly enhance user experience. In this article, we'll guide you through creating a simple yet effective dark/light mode switcher using HTML, CSS, and JavaScript.
## Why Implement Dark/Light Mode?
**1. User Preference:** Some users prefer dark mode for aesthetics or reduced eye strain, especially in low-light environments.
**2. Accessibility:** Improving accessibility by offering a theme that can help visually impaired users.
**3. Battery Saving:** On OLED screens, dark mode can save battery life.
## Setting Up the HTML Structure
Start by creating a simple HTML structure. We'll need a button to toggle between dark and light modes.
```
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Dark/Light Mode Switcher</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<div class="container">
<h1>Dark/Light Mode Switcher</h1>
<button id="modeSwitcher">Switch to Dark Mode</button>
<p>Toggle the button to switch between dark and light modes.</p>
</div>
<script src="script.js"></script>
</body>
</html>
```
## Styling with CSS
Next, we'll define our styles for both dark and light modes. We'll use CSS variables to make switching themes easier.
```
/* styles.css */
:root {
--bg-color: #ffffff;
--text-color: #000000;
--button-bg-color: #000000;
--button-text-color: #ffffff;
}
body {
background-color: var(--bg-color);
color: var(--text-color);
font-family: Arial, sans-serif;
transition: background-color 0.3s ease, color 0.3s ease;
}
.container {
text-align: center;
margin-top: 50px;
}
button {
background-color: var(--button-bg-color);
color: var(--button-text-color);
border: none;
padding: 10px 20px;
cursor: pointer;
transition: background-color 0.3s ease, color 0.3s ease;
}
button:hover {
opacity: 0.8;
}
body.dark-mode {
--bg-color: #333333;
--text-color: #ffffff;
--button-bg-color: #ffffff;
--button-text-color: #000000;
}
```
## Adding JavaScript Functionality
Now, we'll add the JavaScript to handle the theme switch. We'll also save the user's preference in `localStorage` so that their choice persists across sessions.
```
// script.js
document.addEventListener('DOMContentLoaded', () => {
const switcher = document.getElementById('modeSwitcher');
const currentMode = localStorage.getItem('theme') || 'light';
if (currentMode === 'dark') {
document.body.classList.add('dark-mode');
switcher.textContent = 'Switch to Light Mode';
}
switcher.addEventListener('click', () => {
document.body.classList.toggle('dark-mode');
const mode = document.body.classList.contains('dark-mode') ? 'dark' : 'light';
switcher.textContent = mode === 'dark' ? 'Switch to Light Mode' : 'Switch to Dark Mode';
localStorage.setItem('theme', mode);
});
});
```
## Explanation
**1. CSS Variables:** We use CSS variables to define the colors for both modes, making it easy to switch between them.
**2. JavaScript:** We add an event listener to the button to toggle the `dark-mode` class on the `body` element. We also update the button text based on the current mode and save the mode in `localStorage`.
**3. Persistent Theme:** When the page loads, we check `localStorage` for the user's preference and apply the appropriate theme.
## Conclusion
Implementing a dark/light mode switcher enhances user experience by providing visual options that cater to different preferences and conditions. With just a few lines of HTML, CSS, and JavaScript, you can add this valuable feature to your web projects.
Feel free to experiment with more advanced features, such as smooth transitions or additional themes. The possibilities are endless, and your users will appreciate the added flexibility.

> This is also not a sad story, I was so intrigued instead when remembered that time 😜.
The drawback to the past 2020 when COVID-19 outbreak. No job with a very limited budget but need to start a business ASAP to keep me alive.
Shortly... an "Online store with delivery service for the daily consumer needs" was the option. I installed WordPress on a cheap shared hosting which cost me only US$66 for the first 3 years of subscription.
**Theme :**
- Storefront (Free)
**Plugin :**
- WooCommerce (It's Free),
- LSCWP (Free),
- Free WordFence,
- Free Yoast SEO
- My Own plugin to override some functionalities with my "code of convincion" that i break into three parts.
## Part 1 - to tackle the slow performance and to gain more trust 🤩
WordPress on shared hosting will surely give me a headache, it's no Problem. But what if my customer also headache? So part 1 of my "code of convincion" will help to avoid the slow performance and to convince my customer that my business is not cheap.
> This code is not new, I believe everyone has seen these couple of codes since it circular around the internet.

}
}

## Part 2 - to make over and to look more professional 😎
The iconic login page of WordPress will be my office entrance and it's very classic, plus footer section of the storefront theme is very ugly and very possible to degrade my business. So I changed it to convince my prospective customer that my business is professional.
```

• Understanding Hair Loss
Before diving into the treatment, it’s essential to understand why hair loss happens. Common causes include:
1. Genetics: Family history of baldness.
2. Hormonal Changes: Imbalances during puberty, pregnancy, and menopause.
3. Medical Conditions: Thyroid issues, alopecia areata, and scalp infections.
4. Medications: Side effects of certain drugs.
5. Stress and Lifestyle: High-stress levels and unhealthy lifestyle choices.
• Conventional Treatment for Hair Loss
Despite the fact that remedies promising to restore hair to balding heads have been around since ancient times, most men and women with thinning hair can do little to reverse the process. For cosmetic purposes, or after hair loss from surgery or drug treatments, many people turn to wigs, hairpieces, and hair weaving. Some even get tattoos to simulate lost eyebrows and eyelashes. Hair loss is one of the common afflictions of a modern, stressful lifestyle. Healthy hair significantly contributes to self-confidence and self-image. Unfortunately, worrying about hair loss can exacerbate this vicious cycle. Freedom from hair loss might be the key you need for personal and professional success.
Hair loss (alopecia) can affect just your scalp or your entire body, and it can be temporary or permanent. It can result from heredity, hormonal changes, medical conditions, or simply aging. Anyone can experience hair loss, but it is more common in men. Baldness typically refers to excessive hair loss from your scalp. Hereditary hair loss with age is the most common cause of baldness.
Some people choose to let their hair loss run its course untreated and unhidden. Others may cover it up with hairstyles, makeup, hats, or scarves. Still, alternative treatments like homeopathy can be one of the treatments available to prevent further hair loss or to restore growth.
• Symptoms of hair loss might also include:
1) Gradual thinning on top of head.
2) Round or patchy bald spots on scalp.
3) Surprising loosening of hair
4) Complete-body hair loss
5) Patches of scaling that unfold over the scalp. That is a signal of ringworm. It can be followed with the aid of damaged hair, redness, and swelling and, at instances, oozing.
• Modern Homeopathy’s Approach
Modern Homeopathy takes a holistic approach to treating hair loss. Unlike conventional treatments that may involve harsh chemicals or invasive procedures, modern homeopathy focuses on advanced research based remedies that are painless, have no side effects and also promote overall health and well-being. These remedies can be safely used by individuals of all ages. Here’s why it’s considered the best homeopathy treatment for hair loss:
1) Individualized Treatment Plans
Modern Homeopathy recognizes that each individual is unique, and so are their health concerns. Modern Homeopathy practitioners create personalized treatment plans based on a thorough assessment of the patient’s medical history, lifestyle, and specific symptoms. This ensures that the treatment is tailored to address the root cause of hair loss.
2) Boosting Overall Health
One of the key principles of modern homeopathy is to treat the person as a whole rather than just the symptoms. By improving overall health and addressing underlying issues such as nutritional deficiencies, hormonal imbalances, and stress, Modern Homeopathy helps in promoting healthy hair growth and preventing further hair loss.
3) Stress Management
Stress is a significant factor contributing to hair loss. Modern Homeopathy includes techniques and remedies to manage stress effectively, thereby reducing its impact on hair health. Relaxation techniques, lifestyle modifications, and specific stress-relief remedies are part of the comprehensive treatment plan.
• Success Stories
Many individuals have experienced remarkable improvements in their hair health with Modern Homeopathy’s best homeopathy treatment for hair loss. Patients have reported reduced hair fall, improved hair texture, and even regrowth of lost hair. The holistic approach not only addresses hair loss but also enhances overall well-being.
If you’re struggling with hair loss and seeking an effective solution, Modern Homeopathy offers the best homeopathy treatment for hair loss. By addressing the root causes and promoting overall health, homeopathy provides a safe and sustainable way to combat hair loss and achieve healthier, fuller hair.

Fork the repo and use... | 0 | 2024-07-13T08:32:50 | https://dev.to/cschindlbeck/gitlab-repository-manager-1056 | terraform, gitlab, devops, productivity | This guide shows an example on how to automate GitLab settings with Terraform.
Fork the [repo](https://github.com/cschindlbeck/gitlab_repo_manager) and use it as a template to start adapting it for your organization!
You can extend this for various other automation tasks.
## Reasoning and Advantages of this Approach
Are you responsible in your organization for a complex project with many repositories? Are you tired of going through all repositories manually and do such tasks as adding/removing users and setting merge permissions?
By following this guide, you can:
- Save Time: Automate repetitive tasks and focus on what truly matters.
- Reduce Errors: Minimize human errors with consistent automation scripts.
- Improve Productivity: Streamline your workflow and enhance team collaboration.
This guide exemplifies how to leverage Terraform to automate branch protection permissions in GitLab.
## Fictitious example
In this example, branch protection rules for two fictitious teams (backend and frontend) with different repositories respectively, are automated.
The repositories hosted on GitLab and each teams requires specific branch protection rules. The frontend team handles solely frontend repos, and the backend team handles the backend repos.
To get a rough idea, this table summarizes what we want to achieve automatically

## Step-by-Step Explanation
### Initial Setup
Security first, so export your Gitlab PAT (private access token) via the command line, by setting an environment variable with
```bash
export $TF_VAR_gitlab_token=YOURTOKEN
```
in order to avoid exposing sensitive information in your git repo (put it in your .bashrc/.zshrc if you do not want to do this each time you open a terminal). This environment variable is then accessible in HCL (Terraform's own programming language) via `var.gitlab_token` (make sure you give at least repo_read, repo_write permissions for the PAT).
Now we can add the [Gitlab provider](https://registry.terraform.io/providers/gitlabhq/gitlab/latest/docs) to enable Terraform to communicate with Gitlab:
```hcl
terraform {
required_providers {
gitlab = {
source = "gitlabhq/gitlab"
version = "17.1.0"
}
}
}
variable "gitlab_token" {}
provider "gitlab" {
base_url = "https://gitlab.iav.com/api/v4"
token = var.gitlab_token
}
```
Initialize the terraform directory
```bash
terraform init
```
which will download the necessary code for communication with the Gitlab API in a .terraform directory.
### Get a list of frontend and backend repositories
Then, we must obtain a list of all frontend and backend repositories. For simplicity, we assume that these repositories (in Gitlab called "projects") are found in the same directory (in Gitlab called "group").
Enter the path to the group in the next block and
```hcl
# Specify the path to your group
data "gitlab_group" "group" {
full_path = "<YOUR_PATH_TO_YOUR_GROUP>"
}
# Filter repositories for the frontend
data "gitlab_projects" "frontend_projects" {
group_id = data.gitlab_group.group.id
order_by = "name"
include_subgroups = true
search = "frontend" # filter out repos containing the word 'frontend'
}
# Filter repositories for the backend
data "gitlab_projects" "backend_projects" {
group_id = data.gitlab_group.group.id
order_by = "name"
include_subgroups = true
search = "backend" # filter out repos containing the word 'backend'
}
```
These so-called data resources will obtain the current information of the repositories and store them in the terraform.tfstate file. By specifing a search field, we can obtain only the repos that contain a certain word, here front- and backend. This makes them accessible via `data.gitlab_projects.frontend_projects.projects` and `data.gitlab_projects.backend_projects.projects` so that we can change the settings there accordingly. Note that this will only work if the repos adhere to a certain naming scheme, here they must include the words frontend or backend.
### Specify who is admin or dev
Now, let's define who is a backend and a frontend admin or developer, starting with the frontend admins.
You can get the IDs by searching for the person in Gitlab and right-clicking the three dots on the right to copy their ID.
Here, we set a list of frontend admins
```hcl
variable "frontend_admins" {
description = "List of frontend admin ids"
type = list(number)
default = [71, 63]
}
```
And let's repeat the same for the remaining ones with
```hcl
variable "frontend_devs" {
description = "List of frontend dev ids"
type = list(number)
default = [82, 102, 182]
}
variable "backend_admins" {
description = "List of backend admin ids"
type = list(number)
default = [713]
}
variable "backend_devs" {
description = "List of backend dev ids"
type = list(number)
default = [767, 90, 152]
}
```
### Protect branches
Finally we can set our branch protection rules for all the repositories in an automated way.
Let's start with protecting the master branch of the frontend repositories, by including this block.
```hcl
resource "gitlab_branch_protection" "frontend_master_protection" {
for_each = { for project in data.gitlab_projects.frontend_projects.projects : project.id => project }
project = each.value.id
allow_force_push = true
code_owner_approval_required = true
branch = "master"
push_access_level = "no one" # do not push to master directly
merge_access_level = "no one" # we will specify who can push below
dynamic "allowed_to_merge" {
for_each = var.frontend_admins
content {
user_id = allowed_to_merge.value
}
}
}
```
Let's explore this large block in more detail:
- `for_each`: We loop over all our frontend repositories that we gathered in the data block previously
- `allow_force_push`/`code_owner_approval_required`: Allow force push by the admins/Require code owner approval
- `push_access_level`/`merge_access_level`: Set level of push/merge access (no one, developer, maintainer, owner), we allow no role here, but individual accounts
- `allowed_to_merge`: We loop over all frontend admins for merge rights
We set levels to `no one` in this example because backend and frontend devs might both be classified as developer but we want only to include the ones responsible for their part.
Now, we can do the same for the dev branch
```hcl
resource "gitlab_branch_protection" "frontend_dev_protection" {
for_each = { for project in data.gitlab_projects.frontend_projects.projects : project.id => project }
project = each.value.id
allow_force_push = false
code_owner_approval_required = true
branch = "dev"
push_access_level = "developer" # here, let's allow every developer to push, regardless of front- or backend
merge_access_level = "no one" # we will specify who can push below
dynamic "allowed_to_merge" {
for_each = distinct(concat(var.frontend_admins, var.frontend_devs)) # union over devs and admins
content {
user_id = allowed_to_merge.value
}
}
dynamic "allowed_to_push" {
for_each = distinct(concat(var.frontend_admins, var.frontend_devs)) # union over devs and admins
content {
user_id = allowed_to_push.value
}
}
}
```
We follow the same approach as for the master branch with a few differences for the dev branch:
- `allow_force_push`/`code_owner_approval_required`: We disallow force push for anyone here
- `allowed_to_push`/`allowed_to_merge`: We loop over the union of frontend admins and devs to let them have push/merge rights (admins should be able to merge/push too, right?)
Now that we have done this for the frontend repos, we can do this in an analagous fashion for the backend repos by changing only `frontend_projects` to `backend_projects` and `frontend_admins` and `frontend_devs` to `backend_admins` and `backend_devs`, such as
```hcl
...
for_each = { for project in data.gitlab_projects.backend_projects.projects : project.id => project }
...
for_each = distinct(concat(var.backend_admins, var.backend_devs)) # union over devs and admins
```
You can take a look at the entire code [here](https://github.com/cschindlbeck/gitlab_repo_manager), or adapt the settings to your preferences/organizational process.
Now we have every set up to make the changes readily availabe in GitLab.
### Deployment
Finally, we can apply our changes via
```bash
terraform apply
```
Carefully look through the upcoming changes and confirm with `yes` if you are sure everything is set correctly.
Attention: if you have already set up your repos (and settings) in Gitlab, this will fail as Terraform will complain that the resources already exist. In this case, you will need to import the current state to your terraform.tfstate first, so that terraform is able to manage this.
You can do this for each project you want to import via
```bash
terraform import gitlab_project.gitlab_repo_manager <project_id>
```
or, alternatively, for more complex projects, check out [terraformer](https://github.com/GoogleCloudPlatform/terraformer), a CLI tool to import/update your tfstate from existing infrastructure.
## Summary
This guide walked you through an example on how to set up branch protection in multiple Gitlab repos automatically via Terraform. You can take this example as a starting point on how to automate much more settings in Gitlab repos, such as setting the preferred merge method, tag protection, branch rules and much more!
If you host your repos on GitHub you can take this example as a template and take the structure and adapt it step-by-step for the [GitHub provider](https://registry.terraform.io/providers/integrations/github/latest/docs).
The days are numbered where you had to do this manually for (countless) repos in a complex project for every subteam. Embrace the mighty tooling capabilities of Terraform!
Bonus: Check out how to set the preferred merge method (the only correct answer is fast-forward only, right?) in my [github repo](https://github.com/cschindlbeck/gitlab_repo_manager). | cschindlbeck |
1,922,073 | TWS Earphones vs Wired Earphones | TWS Earphones vs Wired Earphones, earphones have undergone significant transformations, providing... | 0 | 2024-07-13T08:31:18 | https://dev.to/bjbjearbuds/tws-earphones-vs-wired-earphones-27ag | TWS Earphones vs Wired Earphones, earphones have undergone significant transformations, providing users with diverse choices tailored to their specific needs. The two major categories that dominate the market today are True Wireless Stereo (TWS) earphones and traditional wired earphones. Each has its own set of advantages and drawbacks, making the choice between them largely dependent on individual preferences and usage scenarios. This article delves into a detailed comparison of TWS earphones and wired earphones to help you decide which is better for your needs.
**What Are TWS Earphones?
**TWS earphones, or True Wireless Stereo earphones, are a type of wireless earphones that completely eliminate the need for any cables or wires, including the one connecting the left and right earpieces. They rely on Bluetooth technology to transmit audio from the source device to the earphones.
**TWS Earphones vs Wired Earphones
****Advantages of TWS Earphones**
Complete Freedom of Movement: Without any wires, TWS earphones provide unparalleled freedom of movement, making them ideal for workouts, commuting, and any on-the-go activities. You can easily store them in a pocket or small case without worrying about tangled cables.
Modern Features: TWS earphones often come equipped with advanced features such as touch controls, voice assistants (like Siri or Google Assistant), and noise cancellation (both active and passive). These features enhance user convenience and audio experience.

Portability: Most TWS earphones come with a compact charging case that not only protects the earphones but also provides additional battery life. This makes them highly portable and ensures they are ready to use whenever you need them.
Style and Comfort: The sleek design and ergonomic fit of TWS earphones make them stylish and comfortable for long-term wear. Many brands offer various sizes of ear tips to ensure a secure fit.
Disadvantages of TWS Earphones
Battery Life: The primary limitation of TWS earphones is battery life. While the charging case can extend usage, the earphones themselves typically offer only a few hours of continuous playback. Users need to remember to recharge them frequently.
Latency Issues: Some TWS earphones can experience latency issues, which can be problematic when watching videos or playing games. This is because the audio signal takes a fraction of a second to be transmitted wirelessly, causing a slight delay.
Cost: High-quality TWS earphones can be quite expensive compared to wired counterparts. The price includes the cost of miniaturized components and advanced technologies packed into a small form factor.
What Are Wired Earphones?
Wired earphones are the traditional type of earphones that connect to your device via a physical cable, typically with a 3.5mm headphone jack or a USB-C/Lightning connector.
**Advantages of Wired Earphones
**
Sound Quality: Wired earphones generally offer superior sound quality due to the direct connection to the audio source. This eliminates any potential interference or compression that might occur with wireless transmission.
Zero Latency: Wired earphones provide a direct connection to the device, resulting in zero audio latency. This makes them ideal for watching videos, gaming, and professional audio work where timing is crucial.
Battery-Free Operation: Wired earphones do not require batteries, making them reliable for continuous use without the need to recharge. This is especially useful for long listening sessions.

In this tutorial we will introduce you to the ZK tech-stack and the tools you can use to build ZK applications for the Celo blockchain.
**Learning Objectives
At the end of this chapter, you will:
- Understand the zK tech stack
- Build a simple zK Circuit
## An Overview of the Celo zK Tech Stack
The Celo blockchain is a Layer 1 protocol and its light client is based on ZK features. However there are rumors and proposals that Celo may transition to a Layer-2 model with a zkEVM.
When looking at ZK applications in Celo at a high level, we can separate the techstack into two sections based on Prover and Verifier.
The Prover side is executed off-chain on a user machine while the Verification takes place on-chain. Now let's dive deeper into the different tools developers can use to develop ZK applications.

## The zK Stack
The main individual components of this stack include the:
1) Celo EVM,
2) prover, and
3) domain-specific language (DSL).

1. The Celo EVM
This is Celo’s Solidity execution environment where smart contract logic would be executed. When designing your ZK application you can write code in solidity that can verify ZK proofs on chain. This is a powerful ability because now your contracts can act based on off-chain proofs (we will expand on this shortly).
2. The Prover
As discussed in previous chapters, a Prover is software that given some input can generate a Proof of some computation. Today there are two mainstream provers that are popular amongst the ZK community: Groth16 provers and plonk based provers.
3. DSL
A DSL (Domain Specific Language) is a programming language (just like Javascript or C++) but is designed to allow developers to express ZK Circuits easily. A ZK Circuit is the component that allows a user to generate a proof (e.g., prove that you paid X-amount of USDC to a client).
A popular DSL for SnarkJS a Groth16 prover is Circom, while a popular DSL for Plonk provers is HALO2.
Let's have a look at an example showing how all these elements come together.
Going over the project
In this tutorial we will be using circom and snarkjs to build our circuits and generate our proofs. If you are using VS code there is a syntax highlighter for circom for VSCode.
Setting up your dependencies
Install nodejs (LTS should be good), and make sure you have nvm installed.
Clone this repo: [](https://github.com/chad11111/zk-celocamp-tutorial )
Clone the submodules: `git submodule update --init --recursive`
Install the packages with `npm i`
## Circom and SnarkJS
Circom is the DSL we will be writing during this tutorial. SnarkJS is a program developed by IDEN3 which allows you to generate all files required to generate and verify your compiled Circom circuits. To understand the relation between Caricom and SnarkJS, let's review a common developer flow.

The diagram above shows the flow of how Snarkjs takes a circuit - a pre generated power of tau (ptau) file and public inputs - and is able to generate verifying and proving keys. These keys can then generate proofs and verify them. In this tutorial we will be using Groth16 which requires a trusted setup and thus for each circuit you will have to generate the setup.
1. What are Ptau Files ?
The .ptau file is related to the "Powers of Tau" ceremony, which is a multi-party computation (MPC) protocol. The Powers of Tau ceremony is a one-time setup that generates a common reference string (CRS) needed to construct and verify zk-SNARK proofs. This CRS is also known as the "structured reference string" (SRS). During the ceremony, participants contribute randomness to the protocol, and the .ptau file accumulates these contributions. The purpose of this is to ensure that as long as one participant in the ceremony is honest and destroys their "toxic waste" (the randomness they used), the final SRS can be considered secure. It's a foundational step in preparing the environment for secure, succinct, and non-interactive proofs where no single party can have enough information to cheat the system.
2. What is a Witness?
In zero-knowledge proofs, a witness refers to the set of values that satisfy the constraints of the arithmetic circuit (or R1CS in the case of zk-SNARKs) for a given instance. Essentially, it is the private input that, along with the public inputs, makes the statement being proven true. The witness demonstrates that the prover knows a solution to the problem without revealing the solution itself.
To generate a proof we first need private and public inputs. If you were to build a full ZK sudoku application, then you would probably receive this information from the user's moves inside the application’s UI.
## Building a Simple Circuit
Let's begin with building a simple circuit to understand the core basics of writing Circom and compiling it with Snarkjs. In this example circuit, given a private input sideLength of a square proves that you know some square of size X without revealing the sideLength.
template SquareAreaProof() {
signal private input sideLength; // The side length of the square, a private input
signal input declaredArea; // The declared area of the square, a public input
signal output isValid; // Output signal to indicate if the proof is valid
// Calculate the actual area by squaring the side length
signal actualArea;
actualArea <== sideLength * sideLength;
// Check if the declared area matches the actual area
isValid <== actualArea === declaredArea;
}
component main = SquareAreaProof();
Let’s define the following key terms: private input, input and output.
private input is a value which only the prover should know.
input is a public input, this input is a value known to the general public.
output is simply a boolean value describing if the proof has passed or not.
If we examine the logic of our circuit we perform a calculation based on the private input sideLength. The computation is simple:
signal actualArea;
actualArea <== sideLength * sideLength;
We calculate the area based on the input. We then proceed to validate that the public input declaredArea is in fact the same as actualArea. These conditions generate constraints which generate a proof. I suggest that you read the official Circom language documentation to gain a more in depth understanding of the Circom language.
## Build Another Simple Circuit
Challenge: Write a circuit that can verify the area of a triangle.

h - height from base
b - length of base
I suggest you approach this exercise in the following steps:
1. Define which inputs are private and which inputs are public.
2. Define the core logic
3. Define the constraint to check if the proof is valid.
Using Dependencies
Every time we create a circuit we are creating a method, and similar to other programming languages, methods can be exported and reused.
`template MyCircuit() {`
This template (MyCircuit) can be imported by other circuits and used to encapsulate logic. A popular example is circomlib, a collection of common circuits ranging from bit operators to hash functions. Let's see how you can use `circomlib`.
First let's create a folder. Name it as you wish, and then enter that folder.
`mkdir <foldername>
cd <foldername>`
Second, initiate a new Node project with npm and install circomlib.
`npm init
npm i circomlib`
For this example let's use `circomlibs` poseidon hash.
Create a new circuit named `PoseidonHasher`.
`pragma circom 2.0.0;
include "node_modules/circomlib/circuits/poseidon.circom";
template PoseidonHasher() {
signal input in;
signal output out;
component poseidon = Poseidon(1);
poseidon.inputs[0] <== in;
out <== poseidon.out;
}
component main = PoseidonHasher();`
In the second line we import `poseidon.circom` we are then able to use it easily, we just saved ourselves many hours of development by importing a ready made primitive.

(路加福音19章)
辛丑年疫情封城的那一年,我祷告上主给我一个选民女人,结果出现了一个在德国的军委大院长大的女人。她用六爻卦预测了疫苗无效,所以拒绝了打疫苗,通过了疫情期间的兽印考试。我对她的特点进行了记录,随后发现,这三个特点是选民的印记,它们分别是:中国术数对应古代希伯来文化在中国的流传,军委大院长大代表启示录四神兽红马在中国的后裔,在德国代表出埃及,迎接欧美秩序。
随后我对中国术数研究,发现了希伯来语的圣经解经和中国的术数思想的一致性。从而解释了它们是一个源头。
今年年初我在北京遇到了一个会中国术数的人,但是她没有出过国,没有进入过欧美秩序。我试图去给她预言,但是她却弃绝了。这样,我终于理解了当时耶稣的心情,古以色列是选民,但是思想境界,眼界需要提升,提升的方法是从古以色列到巴比伦去,这次提升,被认为是巴比伦的流亡。但是如果不流亡,古以色列会腐败下去。正如我在北京遇到的用中国术数的人,她的思想只在今生的沾光,看不到更大更强的力量正在作用。
选民流亡到巴比伦是必须的,为的是提升他们对神的理解,否则他们会在今生沉沦。所以美国秩序进入中国代表了进步,是救赎,而不是沉沦。如果今生的思维不灭亡,选民就无法出埃及,不出埃及就无法进入应许之地,巴比伦的流亡是得到应许之地所必需的。一切都是上主的计划和安排。

1,922,086 | Real-Time 3D: My Journey in Building a C++ OpenGL Rendering Engine | What is a Rendering Engine? A rendering engine abstracts the process of drawing objects... | 28,070 | 2024-07-13T20:02:33 | https://dev.to/yuvsouce/real-time-3d-my-journey-in-building-a-c-opengl-rendering-engine-2bj4 | gamedev, cpp, programming, devjournal |

## What is a Rendering Engine?
A rendering engine abstracts the process of drawing objects on the screen. It uses the GPU to convert logic (e.g., a 3D model) into a 2D image displayed on a screen.
### Motivation:
I've always loved graphics, especially in video games. As a child, I was fascinated by how future graphics would look and how realistic they could become. Besides my personal love for graphics, it's a challenging field. The development of graphics involves interesting mathematical challenges (linear algebra) and requires efficient, optimized coding, often in fast "low-level" languages like C++.
## Game Development:
Beyond the engine and its basic supported capabilities, I developed a scene/game - a kind of maze in a 3D world with impassable objects. I implemented the A* algorithm to find the shortest path between two points. The algorithm is an extension of Dijkstra's algorithm and is widely used in video games, such as finding a path between a player character and a target.
#### Challenges:
Implementing the algorithm was slightly challenging despite its simplicity. The algorithm searches a graph, but I didn't have nodes; I had a 3D world with infinite points. Therefore, I had to convert the world into nodes by defining squares on a map, with each point belonging to a specific square.
#### Optimization:
Deciding the size of the squares was critical. If a blocking object partially occupies a square, should the whole square be considered blocked? Reducing the size of each square increases accuracy but slows down the algorithm. For example, with a 64x64 grid (4,096 squares), reducing the square size by half increases the grid to 128x128 (16,000 squares), significantly impacting algorithm speed and data structure choice.

#### Debugging Tools:
OpenGL is a state machine, making it hard to debug or understand its current state. While it provides basic output for incorrect input, understanding why things don't appear on the screen as expected is challenging. Hence, I decided to develop visual debugging tools to display each square on the map, mark objects and their occupied squares, and visualize algorithm paths. This decision saved time by providing visual confirmation of what was happening on the screen.
## Video Demonstration:
The attached video demonstrates dynamic lighting, various backgrounds and textures, model loading, and a scene with a sofa, computer, and other elements. Towards the end, a penguin aims to reach a bench along the shortest path. The A* algorithm is visually represented, with red nodes indicating closed nodes and green nodes representing the shortest path. The algorithm operates instantly, but the animation is intentionally slowed down for clarity.
Note: I later updated the interface, so the video is from before the change. Therefore, the images of the engine are different.

It... | 0 | 2024-07-13T09:15:48 | https://dev.to/gddh_gdjdh_652d4423f5f12c/gasoline-diesel-generators-maintenance-and-care-tips-5dd5 | design | Gasoline diesel generators are all-purpose machines that work as a constant power resource. It provides novel solution to unsteady power generation especially out in forest and can also be used as a grid-independant based back-up generator for your home or office. Because the generators are portable, simple to operate and provide stable power supply as opposed to powered by other sources. Also, they are standalone and do not require to be connected to power grid or weather dependence. These features make gasoline diesel pumps generators preferred for different activities including camping, outdoor events and construction projects.
As time have passed, Gasoline diesel generators has dramatically improved through the innovation providing higher performance and reliability. Most contemporary generators use electronic controls to maintain the output of power and ensure that fuel is consumed efficiently. On top of this, the refreshed models are also quieter than their predecessors and can be used indoors or in settings where reducing decibel levels is a concern.
Gasoline diesel generators are guaranteed not to explode and cause some accidents when they use, so I believe that safety is still the most important. You must read and carefully follow the manufacturer's instructions in order to play safe. Keep the generator clear of flammable materials, and never operate it in an enclosed space (such as a garage) to avoid dangerous carbon monoxide buildup that can kill you. Operation: Never operate the generator indoors, near open windows or inside of any living areas and be sure proper ventilation while it is running.
A Diesel Generator is pretty simple to use, but it requires a few steps on your part in order for you get the maximum performance. Before you run the generator, make sure there is fuel and oil in it if no fill accordingly;; check for amount of iol them add more. Plug your load into the silent generator, and then turn on the engine by turning a key (for electric start) or pulling on a cord; once running adjust throttle as needed. Remember to close the generator and let it cool down before you put it away.
Servicing is important in keeping the reliability and durability of your Gasoline Diesel Generator There will still the need to observe regular oil and air filter changes, as well as occasionally inspecting (but not replacing) spark plugs so sticking with a schedule like Subaru outlined is crucial. Also, you must use good fuel and oil because inferior quality of the materials can cause damage in the engine or may prevent it to work.
Gasoline diesel generators are highly versatile and suitable for home use, with a robust backup power system that can provide electricity to your home, small business or outdoor events; construction sites, emergency facilities like hospitals. 3. They are also one of the top choices for both campers, Rvers and dwellers alike. These generators are getting cleaner with technology thats progressing and efficient advanced too, which makes them a simple option for many different applications.
Ultimately, gas diesel generators are reliable and provide power efficiently that can be used both in residential or commercial environments some advantages including portability, easy maintenance and is much more cost-effective. But rightly maintaining your hair extension is necessary for performance. Following the manufacturer's service advice and putting good power pressure washer quality fuel and oil in help keep this generator gasser rolling along. Emphasizing on safety, adhering to the guidelines,and understanding more of what gasoline diesel generator can offer will help you take advantage of them as a power backup when natural disasters and outages occur. | gddh_gdjdh_652d4423f5f12c |

1,922,097 | Know Backend of Stake’s Mine Game | Hey there, fellow game enthusiasts! 🎮 I’ve recently built a Mine Game, and I’m excited to share how... | 0 | 2024-07-13T09:32:46 | https://dev.to/hemantcode625/know-backend-of-stakes-mine-game-2d11 | gamedev, webdev, redis, graphql | Hey there, fellow game enthusiasts! 🎮
I’ve recently built a Mine Game, and I’m excited to share how the backend is designed. If you’re curious about how such games work behind the scenes, you’re in the right place!

**What is a Mine Game?**
First things first, let’s quickly recap what a Mine Game is. Inspired by Stake’s popular version, it’s a betting game where players reveal tiles on a grid, hoping to avoid mines. Each safe tile increases their winnings, but hitting a mine means losing the bet.
**Tech Stack**
Frontend: Vite and React
Styling: Tailwind CSS
Backend: Node.js with Redis and GraphQL
**Designing the Backend**
When a user starts a game, a unique game ID is generated. The game data includes fields like mineCount, mineField, bettingAmount, multiplierArray, and isGameOver. The mineField is not sent in queries but rather in mutations to prevent cheating or malpractices.
**GraphQL Resolvers**
Here’s how I implemented the backend using GraphQL resolvers:
```
const resolvers = {
Query: {
getGameResults: async (_, { gameId }) => {
const gameData = await redis.get(gameId);
const game = JSON.parse(gameData);
return {
mineCount: game.mineCount,
mineField: game.gameOver ? game.mineField : [],
betAmount: game.betAmount,
multiplier: game.multiplier,
isWinner: game.betAmount * game.multiplier > 0 ? true : false,
rounds: game.isWinner ? game.rounds : game.rounds + 1,
winningAmount:
game.multiplier == null ? 0 : game.betAmount * game.multiplier,
updatedAt: game.updatedAt,
};
},
},
Mutation: {
startGame: async (_, { betAmount, mineCount }) => {
const gameId = uuidv4();
const mineField = generateMineField(mineCount);
const multiplierArray = generatePayoutMultipliers(25, mineCount, 0.98);
const updatedAt = new Date().toISOString();
const gameData = {
mineField,
betAmount,
mineCount,
gameOver: false,
rounds: -1,
positionSelected: [],
multipliers: multiplierArray,
updatedAt,
};
await redis.set(gameId, JSON.stringify(gameData));
return { gameId, betAmount, mineCount, updatedAt };
},
cashoutResult: async (_, { gameId }) => {
const gameData = await redis.get(gameId);
const game = JSON.parse(gameData);
game.gameOver = true;
await redis.set(gameId, JSON.stringify(game));
return {
mineCount: game.mineCount,
mineField: game.gameOver ? game.mineField : [],
betAmount: game.betAmount,
multiplier: game.multiplier,
isWinner: game.betAmount * game.multiplier > 0 ? true : false,
rounds: game.isWinner ? game.rounds : game.rounds + 1,
winningAmount:
game.multiplier == null ? 0 : game.betAmount * game.multiplier,
updatedAt: game.updatedAt,
};
},
selectTile: async (_, { gameId, position }) => {
const gameData = await redis.get(gameId);
const game = JSON.parse(gameData);
if (game.gameOver) {
return {
multiplier: game.multiplier,
};
}
if (!Array.isArray(game.positionSelected)) {
game.positionSelected = [];
}
if (!game.positionSelected.includes(position)) {
game.positionSelected.push(position);
game.rounds += 1;
}
const isMine = game.mineField[position] === "M";
const isGem = game.mineField[position] === "G";
const updatedAt = new Date().toISOString();
game.isMine = isMine;
game.updatedAt = updatedAt;
if (isMine) {
game.gameOver = true;
game.isWinner = false;
game.multiplier = 0;
game.winningAmount = 0;
} else if (
isGem &&
!game.gameOver &&
game.rounds < game.multipliers.length
) {
game.multiplier = game.multipliers[game.rounds].payoutMultiplier;
game.winningAmount = game.betAmount * game.multiplier;
} else if (game.gameOver) {
throw new Error("Game over. You can't select any more tiles.");
} else {
throw new Error("Invalid rounds index for multipliers array.");
}
await redis.set(gameId, JSON.stringify(game));
return {
isMine,
multiplier: game.multiplier,
winningAmount: game.winningAmount,
updatedAt,
};
},
},
};
```
**Wrapping Up**
Building the backend for a Mine Game was a fantastic learning experience. If you’re interested in game development or just curious about how such games work, I hope this overview helps you get started!
Soon gonna add a payment gateway to manage wallet and deploying it on AWS EKS.

1,922,113 | Conan: Your Embedded Cross-Compilation Champion | In the continuously changing field of software development, modern programming languages such as Rust... | 0 | 2024-07-13T11:21:31 | https://dev.to/khozaei/conan-your-embedded-cross-compilation-champion-5bb9 | conan, cmake, embedded, crosscompile | In the continuously changing field of software development, modern programming languages such as Rust and Go have established new standards by integrating built-in package managers. These tools have greatly simplified the development process, allowing developers to easily handle dependencies, improve their workflows, and boost productivity. The convenience provided by these package managers underscores the necessity for a strong solution for C++ development.
Conan is a revolutionary package manager created for C++ developers. Conan simplifies and streamlines package management within the C++ ecosystem, making library and dependency management easier than ever. One of Conan's standout features is its strong support for cross-compiling, which is essential for developers working on embedded systems and applications that target multiple architectures.
Conan's cross-compiling capabilities simplify the development process by enabling developers to build and test their applications for different target environments from a single setup. This feature is especially beneficial for projects that need to run on various hardware configurations, ensuring compatibility and performance across the board.
Moreover, Conan supports a wide range of libraries, offering a vast repository that developers can leverage to enhance their projects. This extensive library support ensures that developers have access to the tools and resources they need, reducing the time spent on configuring and managing dependencies.
For organizations with specific requirements, Conan provides the flexibility to manage private packages using Artifactory Community Edition. This integration ensures that sensitive or proprietary packages remain secure and accessible only to authorized personnel, maintaining the integrity and confidentiality of the development process.

## 1. Integrate Conan as a Dependency Using CMake
CMake's `FetchContent` module is a powerful feature introduced in CMake 3.11 that allows you to download and incorporate external content (such as source code or scripts) directly into your build process. It is particularly useful for managing project dependencies without requiring pre-installed libraries or packages.
### 1.1. Key Features of `FetchContent`
- **Download and Include External Projects**: `FetchContent` can download content from URLs, Git repositories, or local paths. This content can then be included in your build as if it were part of your source tree.
- **Version Control**: By specifying the exact URL or Git tag/branch/commit, you can ensure that your project always uses a specific version of the external content, providing stability and reproducibility.
- **Automatic Integration**: The fetched content can be automatically integrated into the CMake build system, making it straightforward to compile and link against the downloaded content.
- **Configuration and Customization**: You can configure the fetched content using CMake variables, enabling customization and fine-tuning of how the external content is built and used.
### 1.2. Resolve Canon Dependency in CMake
To handle different host operating systems using CMake's FetchContent, you can conditionally fetch and configure dependencies based on the detected operating system. For our example, we focused on implementing it on a Linux host machine.
```cmake
include(FetchContent)
FetchContent_Declare(conan
URL https://github.com/conan-io/conan/releases/download/2.3.2/conan-2.3.2-linux-x86_64.tgz
)
FetchContent_Populate(conan)
if (conan_POPULATED)
set(CONANEXE ${conan_SOURCE_DIR}/conan)
set(CONAN_AVAILABLE TRUE)
endif()
```

## 2. Defining Profiles for Cross-Compiling
In Conan, profiles are used to define settings, options, environment variables, and tools that should be used during the package creation and consumption process. When cross-compiling, it's essential to distinguish between the build and host profiles, and define appropriate toolchains for each.
### 2.1. Build Profile
The build profile specifies the environment where the build tools will run. This is typically your native machine (e.g., x86_64 Linux) which compiles code.
```ini
[settings]
arch=x86_64
build_type=Release
compiler=gcc
compiler.cppstd=gnu17
compiler.libcxx=libstdc++11
compiler.version=12
os=Linux
```
### 2.2. Host Profile
The host profile specifies the environment where the compiled package will run. This can be a different architecture or platform, such as ARM for embedded systems.
```ini
[settings]
arch=armv8
build_type=Release
compiler=clang
compiler.cppstd=17
compiler.libcxx=libc++
compiler.version=12
os=Linux
[buildenv]
CC=/usr/local/mdc_sdk_llvm/dp_gea/mdc_cross_compiler/bin/clang
CXX=/usr/local/mdc_sdk_llvm/dp_gea/mdc_cross_compiler/bin/clang++
LD=/usr/local/mdc_sdk_llvm/dp_gea/mdc_cross_compiler/bin/lld
SYSROOT=/usr/local/mdc_sdk_llvm/dp_gea/mdc_cross_compiler/sysroot
CXXFLAGS=--sysroot=/usr/local/mdc_sdk_llvm/dp_gea/mdc_cross_compiler/sysroot
CFLAGS=--sysroot=/usr/local/mdc_sdk_llvm/dp_gea/mdc_cross_compiler/sysroot
```

## 3. Third-Party Libraries Using Conan
Conan Center is a central repository of open-source packages, which includes a wide range of libraries ready to be integrated into your projects.
### 3.1. Searching for Libraries in Conan Center
- **Visit Conan Center**: Go to [Conan Center](https://conan.io/center) to browse or search for libraries.
- **Search for a Library**: Use the search bar to find the library you need. For example, if you are looking for the `eigen` library, type "eigen" in the search bar.
- **Select the Library**: Click on the library from the search results to view its details, including versions, available options, and usage instructions.
### 3.2. Creating a `conanfile.txt` File
The `conanfile.txt` file is used to define the dependencies and configurations for your project. Here’s an example `conanfile.txt` for a project that depends on `Eigen` and `Boost` libraries:
```ini
[requires]
eigen/3.4.0
boost/1.85.0
[generators]
CMakeDeps
CMakeToolchain
[layout]
cmake_layout
```

## 4. Integrating Conan with CMake
Integrating Conan with CMake is a common practice to streamline dependency management in C++ projects. Conan handles the downloading and management of dependencies, while CMake orchestrates the build process.
```cmake
if (${CONAN_AVAILABLE})
execute_process(COMMAND "${CONANEXE}" install conanfile.txt --build=missing --profile:build=conan.build --profile:host=conan.host
WORKING_DIRECTORY ${PROJECT_SOURCE_DIR})
endif()
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} ${CMAKE_BINARY_DIR}/Release/generators)
include(conan_toolchain)
find_package(Eigen3 REQUIRED)
find_package(Boost REQUIRED COMPONENTS filesystem)
add_executable(${PROJECT_NAME} main.cpp)
target_link_libraries(${PROJECT_NAME} Eigen3::Eigen Boost::filesystem)
```

## 5. Use Libraries in Your Code
Now you can include and use the `Eigen` and `Boost` libraries in your `main.cpp` or other source files.
```C++
#include <iostream>
#include <Eigen/Dense>
#include <boost/filesystem.hpp>
int main() {
// Create a 2x2 matrix
Eigen::MatrixXd m(2, 2);
m << 1, 2,
3, 4;
// Add another matrix
Eigen::MatrixXd v(2, 2);
v << 5, 6,
7, 8;
m = m + v;
// Print the resulting matrix
std::cout << "Resulting matrix:\n" << m << std::endl;
boost::filesystem::path my_file = "data.txt";
// Check if the file exists
if (boost::filesystem::exists(my_file)) {
std::cout << my_file << " exists." << std::endl;
} else {
std::cout << my_file << " does not exist." << std::endl;
}
// Create a directory (if it doesn't exist)
boost::filesystem::path my_dir = "test_dir";
if (!boost::filesystem::exists(my_dir)) {
boost::filesystem::create_directory(my_dir);
std::cout << "Created directory: " << my_dir << std::endl;
}
return 0;
}
```

So, you're curious about artificial intelligence and want to dive into the world of deep learning? Great choice! TensorFlow, a powerful open-source platform, is a fantastic starting point. In this post, we'll walk you through building your very first neural network. No prior experience? Don't worry, we'll break it down step-by-step.
**What is TensorFlow?**
TensorFlow is like a versatile toolkit for creating and training various machine learning models. It's used for everything from image recognition to natural language processing. Think of it as your trusty companion on this AI journey.
**Setting Up Your Environment**
Before we start coding, let's ensure you have the right tools. You'll need:
**Python installed**
TensorFlow installed (use pip install tensorflow in your terminal)
A basic understanding of Python programming
**Building Your First Neural Network**
1. Import Necessary Libraries:
**Python**
import tensorflow as tf
import numpy as np
**Prepare Your Data:**
For simplicity, we'll use a small dataset. Imagine you want to predict house prices based on square footage.
Python
# Sample data
houses = np.array([1000, 1500, 2000, 2500, 3000])
prices = np.array([100, 150, 200, 250, 300])
**Create the Model:**
Python
model = tf.keras.Sequential([
tf.keras.layers.Dense(1, input_shape=[1])
])
**Compile the Model:**
Python
model.compile(loss='mean_squared_error', optimizer='adam')
**Train the Model:**
Python
model.fit(houses, prices, epochs=100)
**Make Predictions:**
Python
new_house = np.array([1800])
predicted_price = model.predict(new_house)
print(predicted_price)
**Understanding the Code**
- We imported TensorFlow and NumPy.
- Created sample house sizes and prices.
- Defined a simple neural network with one layer.
- Compiled the model with a loss function and optimizer.
- Trained the model on our data.
- Predicted the price of a new house.
**Conclusion**
> Congratulations! You've built your first neural network using TensorFlow. While this is a basic example, it lays the foundation for more complex models. Remember, practice is key. Experiment with different datasets, architectures, and hyperparameters to improve your skills.
