Here is how it works in detail:
1️⃣ Smart Contract Guarantee
BitPower Loop uses smart contract technology to automatically execute all lending transactions. This automated execution eliminates the possibility of human intervention and ensures the security and transparency of transactions. All transaction records are immutable and publicly available on the blockchain.
2️⃣ Decentralized Lending
On the BitPower Loop platform, borrowers and suppliers borrow directly through smart contracts without relying on traditional financial intermediaries. This decentralized lending model reduces transaction costs and provides participants with greater autonomy and flexibility.
3️⃣ Funding Pool Mechanism
Suppliers deposit their crypto assets into BitPower Loop's funding pool to provide liquidity for lending activities. Borrowers borrow the required assets from the funding pool by providing collateral (such as cryptocurrency). The funding pool mechanism improves liquidity and makes the borrowing and repayment process more flexible and efficient. Suppliers can withdraw assets at any time without waiting for the loan to expire, which makes the liquidity of BitPower Loop contracts much higher than peer-to-peer counterparts.
4️⃣ Dynamic interest rates
The interest rates of the BitPower Loop platform are dynamically adjusted according to market supply and demand. Smart contracts automatically adjust interest rates according to current market conditions to ensure the fairness and efficiency of the lending market. All interest rate calculation processes are open and transparent, ensuring the fairness and reliability of transactions.
5️⃣ Secure asset collateral
Borrowers can choose to provide crypto assets as collateral. These collaterals not only reduce loan risks, but also provide borrowers with higher loan amounts and lower interest rates. If the value of the borrower's collateral is lower than the liquidation threshold, the smart contract will automatically trigger liquidation to protect the security of the fund pool.
6️⃣ Global services
Based on blockchain technology, BitPower Loop can provide lending services to users around the world without geographical restrictions. All transactions on the platform are conducted through blockchain, ensuring that participants around the world can enjoy convenient and secure lending services.
7️⃣ Fast Approval and Efficient Management
The loan application process has been simplified and automatically reviewed by smart contracts, without the need for tedious manual approval. This greatly improves the efficiency of borrowing, allowing users to obtain the funds they need faster. All management operations are also automatically executed through smart contracts, ensuring the efficient operation of the platform.
Summary
BitPower Loop provides a safe, efficient and transparent lending platform through its smart contract technology, decentralized lending model, dynamic interest rate mechanism and global services, providing users with flexible asset management and lending solutions.

1,917,265 | How personalisation works in Sitecore XM Cloud | In my previous article, I shared a comprehensive troubleshooting guide for Sitecore XM Cloud tracking... | 0 | 2024-07-11T11:07:43 | https://www.byteminds.co.uk/blog/how-personalisation-works-in-sitecore-xm-cloud | sitecore, xmcloud, personalization, webdev | In my previous article, I shared a comprehensive [troubleshooting guide for Sitecore XM Cloud tracking and personalisation](https://dev.to/byteminds_agency/troubleshooting-tracking-and-personalisation-in-sitecore-xm-cloud-2n6). The guide addresses common issues, explains investigation steps and provides solutions for these issues.
However, understanding how the personalisation engine works in depth can further help in diagnosing persistent issues and developing personalised websites. This article visualises what happens behind the scenes when you enable personalisation and tracking in your Sitecore XM Cloud applications.
## Overview of the personalisation workflow
Before we start, let's familiarise ourselves with key elements of the diagram we are going to look at.
1. On the left hand site we can see the **Browser**, it is responsible for sending requests to our application and displaying the result to end users.
2. The **JSS app** sits at the top centre of the diagram and it represents the Rendering Host role in Sitecore Headless topology. It is the application that processes incoming requests and handles the presentation layer. In this case it is a Next.js application based on the [XM Cloud foundation template](https://doc.sitecore.com/xmc/en/developers/xm-cloud/getting-started-with-xm-cloud.html).
3. **Edge / XM API** is shown on the right hand side, it is a GraphQL endpoint that returns layout definition and content for requested pages, including [personalised variants](https://doc.sitecore.com/xmc/en/users/xm-cloud/create-a-page-variant.html). It can be Experience Edge API for cloud-based setups or a local CM container API endpoint for development purposes.
4. Finally, at the bottom we can see **Tracking & Interactive API** powered by the embedded instance of Sitecore CDP & Personalize. This is where [audiences](https://doc.sitecore.com/xmc/en/users/xm-cloud/creating-an-audience.html) are stored, [conditions](https://doc.sitecore.com/xmc/en/users/xm-cloud/specifying-variables-for-conditions.html) are executed and [analytics](https://doc.sitecore.com/xmc/en/users/xm-cloud/analyze.html) is collected.
When we talk about Next.js applications, there are two main rendering methods: **Server-Side Rendering (SSR)** and **Static Site Generation (SSG)**. Sitecore XM Cloud personalisation engine works slightly differently with these two approaches so we will cover both of them to understand their specifics.
## Server-Side Rendering
This is what happens when a website visitor opens a page that has personalised variants.
**Step 1.** When a user loads the website or navigates to a new page, the browser sends an HTTP request to the Next.js application, including cookies and HTTP headers that can be used in personalisation conditions.
**Step 2.** The Next.js application runs all registered middleware modules, with the [Personalize middleware](https://doc.sitecore.com/xmc/en/developers/jss/220/jss-xmc/personalization-in-jss-next-js-applications.html) being of particular interest. This middleware sends an API request to the GraphQL endpoint to fetch all personalised variants for the current page configured in the CMS.
If there are no personalised variants configured for this page or the page is not found, this middleware will exit and page generation will continue as usual.
**Step 3.** If a page has more than one variant, the middleware sends another API request to the Personalize API to detect if the current visitor matches any of the audiences configured for this page. This is where cookies and HTTP headers received from the browser will help as they will be passed to the Personalize API to identify the visitor.
**Step 4.** By combining responses from these two API requests, the middleware determines which personalised page variant is suitable for the current visitor (cat-themed page in the diagram below 😺).
If the visitor matches an audience configured for the page, the middleware will rewrite the page path to a special personalised variant path (for example, from `/_site_Test/Pets` to `/_variantId_0dd7b00680be49c6815ca4d0793a36da/_site_Test/Pets`) and this will instruct the Next.js application to use the specific page variant when rendering the page. So the personalised version of the page will be rendered on the server and returned to the browser.
If the visitor does not match any audiences, then the default page variant will be rendered and returned to the user.
**Step 5.** Once the page is rendered in the browser, a special React component responsible for tracking will send an API request to the CDP Stream API to register the page view, including which personalised variant was shown. This data is later will be aggregated and shown in analytics reports.
## Static Site Generation (SSG)
The SSG process flow is similar to SSR but has some specifics related to this rendering method. Now, let's see what are these differences.
**Step 1.** This step is exactly the same as for SSR - the browser sends an HTTP request to the Next.js application with cookies and HTTP headers.
**Step 2.** This is where things get different from the SSR process. When the Personalize middleware kicks in, it checks if there are any pre-rendered page variants for this page (the default, cat-themed 😺 and dog-themed 🐶 variants in the diagram). If yes, it skips the API request to the Edge / XM API, otherwise it will fall back to the standard SSR process and fetch personalised variants for the current page.
**Step 3.** This step is the same as in the SSR flow - if a page has personalised variants, the middleware sends an API request to the Personalize API to identify visitor's audience.
**Step 4.** If there is a match and personalised page variants are pre-generated, the middleware will rewrite the page path and then the appropriate personalised page variant will be chosen and returned to the browser (looks like it's the cat-themed variant again! 😺).
If there are no pre-generated personalised variants, but they exist in the CMS and the visitor matches one of the audiences, then the middleware will rewrite the page path, the Next.js app will generate the page variant and save the static output for future requests. This is the default process, see notes at the end of the article to learn more about static generation of personalised page variants.
If the visitor does not match any audiences, then the default page variant will be returned to the user using the statically generated HTML if it exists.
**Step 5.** As with SSR, once the page is returned to the browser the `CdpPageView` React component will send an API request to track the page view event for reporting.
As you can see, the flow is very similar for SSR and SSG. The SSG method with static HTML generation and skipping some API requests can give us a performance boost, especially for websites with high traffic and personalisation enabled on frequently visited pages.
## Notes
### Personalize middleware
The middleware is provided by Sitecore as a part of the [JSS XM Cloud add-on for Next.js](https://doc.sitecore.com/xmc/en/developers/jss/220/jss-xmc/the-jss-xm-cloud-add-on-for-next-js.html). Please note that this add-on is compatible with JSS version 21.6 and later. For earlier versions the [Next.js Personalize add-on](https://doc.sitecore.com/xmc/en/developers/jss/215/jss-xmc/the-next-js-personalize-add-on.html) is used that is now obsolete.
This add-on is only compatible with Sitecore XM Cloud due to specific naming conventions and pre-configured settings required for the embedded CDP and Personalize instance.
### Build-time static generation of personalised page variants
To expand on the step 4 of SSG process, let's see when exactly personalised page variants are generated. As you may know, hosting providers often limit the time available for SSG builds. By default, pre-generation of personalised page variants during build is disabled in to avoid long build times.
However, if sufficient build time is available (for example, your website does not have too many pages) or you have critical personalisation rules on key pages (for instance, you only have a small number of personalised variants on the homepage or an important campaign page), then SSG for personalised variants [can be explicitly enabled](https://doc.sitecore.com/xmc/en/developers/jss/220/jss-xmc/walkthrough--configuring-personalization-in-a-next-js-jss-app.html#enable-static-generation-for-personalized-variants).
This can be done by modifying the file `src/lib/sitemap-fetcher/plugins/graphql-sitemap-service.ts` and setting the `includePersonalizedRoutes` parameter to `true` in the sitemap service constructor:
```
this._graphqlSitemapService = new MultisiteGraphQLSitemapService({
clientFactory,
sites: [...new Set(siteResolver.sites.map((site: SiteInfo) => site.name))],
includePersonalizedRoutes: true,
});
```
Just make sure to watch your build time after enabling this setting to avoid build failing or incurring unnecessary hosting costs.
---
Sitecore XM Cloud provides robust support for personalisation out-of-the-box for both SSR and SSG rendering methods. The add-on with Personalize middleware and CDP tracking component streamlines the process of fetching, matching, and delivering personalised content to website visitors while tracking interactions for reporting.
Hope this article helps to understand the entire process of personalisation and tracking in XM Cloud and allows you to build well-performing and personalised applications. Feel free to share your thoughts and questions in the comments!

They are teaching python free that's an impressive approach of them.. really welcome this approach and thanks for this approach.
However,teaching is good.but they really bored in first class
Besides,I really loved the name parottasalna...in my point of view that's seems to be unique

I'm reaching out for help with a persistent issue we've been experiencing in our React application whenever users translate the page using Google Translate.
We have the following error message:
`NotFoundError: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node.`
This error seems to occur consistently and is proving difficult to resolve. We've already investigated various resources, including this https://martijnhols.nl/gists/everything-about-google-translate-crashing-react on Google Translate issues with React.
Despite these efforts, the problem persists.
Example Issue in Code
We've already tried to address this issue by wrapping strings in spans or fragments using both the ternary and "And (&&)" operators in our React components. However, we don't believe this fully solves all our problems.
Here's an example how we tried to fix this issue:
```
JSX:
{checked && <span>checked</span>}
or
JSX:
{checked ? <>checked</> : <>not checked</>}
```
**Sentry Issue Trace**
Additionally, here is a snippet from our Sentry logs that shows where the error is being thrown in react-dom.production.min.js:
`{snip} c=c.stateNode,8===a.nodeType?a.parentNode.removeChild(c):a.removeChild(c)):X.removeChild(c.stateNode));break;case 18:null!==X&&(Xj?(a=X,c=c. {snip}`
Logger Output:
`{
"arguments": [
{
"message": "Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node.",
"name": "NotFoundError",
"stack": "Error: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node.

Has anyone else encountered this issue, especially in applications using Google Translate? Are there known workarounds or fixes that can be implemented to prevent this error?
Any insights or suggestions on how to tackle this problem would be greatly appreciated. We are looking for a more robust solution to ensure our application remains stable and user-friendly even when translated.
Reminder: "noTranslation" is not an option for us, we need to find a proper way to work around this issue.
Thank you in advance for your help! | mikex95 | |
1,917,288 | Guard dans Angular | Introduction Dans cet article, nous allons explorer comment utiliser les gardes (guards)... | 0 | 2024-07-09T12:20:32 | https://dev.to/bilongodavid/guard-dans-angular-1o76 | javascript, angular, website |
### Introduction
Dans cet article, nous allons explorer comment utiliser les gardes (guards) avec Angular 17. Les gardes permettent de protéger les routes et de vérifier certaines conditions avant de permettre l'accès à une route spécifique.
### Qu'est-ce qu'un Garde Fonctionnel ?
Un garde fonctionnel dans Angular est une fonction utilisée pour intercepter et potentiellement bloquer la navigation vers une route. Avec Angular 17, vous utilisez `CanActivateFn` pour créer des gardes fonctionnels.
### Exemple de Code
Voici un exemple de garde fonctionnel `authGuard` :
```typescript
import { CanActivateFn } from '@angular/router';
import { inject } from '@angular/core';
import { Router } from '@angular/router';
import { AuthService } from './auth.service';
export const authGuard: CanActivateFn = (route, state) => {
const authService = inject(AuthService);
const router = inject(Router);
if (authService.isLoggedIn()) {
return true;
} else {
router.navigate(['/login']);
return false;
}
};
```
### Utilisation du Garde
Pour utiliser ce garde, vous devez le configurer dans votre module de routage en utilisant `provideRouter` et `withGuards` :
```typescript
import { bootstrapApplication } from '@angular/platform-browser';
import { provideRouter, withGuards } from '@angular/router';
import { AppComponent } from './app/app.component';
import { authGuard } from './app/guards/auth.guard';
const routes = [
{ path: 'protected', component: ProtectedComponent, canActivate: [authGuard] }
];
bootstrapApplication(AppComponent, {
providers: [
provideRouter(routes, withGuards())
]
}).catch(err => console.error(err));
```
### Explication du Code
- **CanActivateFn** : Un type représentant une fonction de garde.
- **inject** : Fonction pour injecter des dépendances comme des services.
- **Router** : Service de routage pour naviguer vers d'autres routes.
- **authGuard** : Fonction de garde vérifiant si l'utilisateur est authentifié.
### Conclusion
Les gardes fonctionnels dans Angular 17 offrent une manière flexible et puissante de protéger les routes et de gérer les autorisations. Ils sont particulièrement utiles pour des tâches telles que l'authentification et le contrôle d'accès.
Pour plus de détails, consultez la [documentation officielle d'Angular sur les gardes](https://angular.io/api/router/CanActivateFn)【20†source】【22†source】【23†source】. | bilongodavid |

Let's dive into the world of **CSS Media Queries** and explore how they enhance responsive web design.
## Understanding CSS Media Queries
CSS Media Queries allow us to adapt the presentation of content based on different viewport sizes. The viewport represents the visible area of a web page, which varies depending on the device used to access the site¹. These queries are essential for creating responsive designs that look great on various screens.
## Traditional Syntax
In the past, we used the following syntax to apply styles based on viewport width:
```css
/* When the viewport width is at least 600px */
@media (min-width: 600px) {
.element {
/* Style away! */
}
}
```
## The New Syntax
The Media Queries Level 4 specification introduces a more concise and intuitive syntax using comparison operators. These operators allow us to directly compare values instead of combining conditions with the `and` operator¹:
- `<`: Evaluates if a value is less than another value.
- `>`: Evaluates if a value is greater than another value.
- `=`: Evaluates if a value is equal to another value.
- `<=`: Evaluates if a value is less than or equal to another value.
- `>=`: Evaluates if a value is greater than or equal to another value.
Now, let's rewrite the previous example using the new syntax:
```css
/* When the viewport width is 600px or greater */
@media (width >= 600px) {
.element {
/* Style away! */
}
}
```
## Targeting Ranges
Often, we create breakpoints in our designs—conditions where the layout "breaks" and specific styles are applied. These breakpoints typically depend on the viewport being between two widths. With the new syntax, we can easily target a range of viewport widths:
```css
/* When the viewport width is between 600px and 1200px */
@media (width >= 600px) and (width <= 1200px) {
.element {
/* Style away! */
}
}
```
By embracing these new comparison operators, we can write cleaner, more expressive media queries for responsive web design. Happy coding! 🚀🎨 | koolkamalkishor | |

I wonder if I can use pyenv and pipenv on Fedora Workstation 40 although I don't use these utilities in my personal projects. And the answer is yes.
The steps are as follow:
## Install dependencies
```shell
sudo dnf builddep python3
```
## Install pyenv
```shell
curl https://pyenv.run | bash
```
I know that you don't like running Bash script immediately from cURL.
## Modify .bashrc
Pyenv normally told you to append these lines to .bashrc, and the restart your terminal.
```
export PYENV_ROOT="$HOME/.pyenv"
[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init -)"
# Restart your shell for the changes to take effect.
# Load pyenv-virtualenv automatically by adding
# the following to ~/.bashrc:
eval "$(pyenv virtualenv-init -)"
```
## Install Python via Pyenv
```
pyenv install 3.10 # You can choose other versions
```
I know that we can install Python using configure and make like many other packages, but you can use pyenv as well.
## Set default python
```
pyenv global 3.10 # or other version
```
And then restart your terminal.
## And finally, install pipenv
```
pip install pipenv
```

The Covid pandemic altered... | 0 | 2024-07-09T12:26:22 | https://dev.to/infowindtech57/dedicated-software-development-team-accelerate-your-development-42oa | softwaredevelopment | In today’s rapidly changing technology world, this strategy is essential. The Covid pandemic altered our approach to work. The prevalence of remote teams has made it simpler to locate competent engineers worldwide. We’ll talk about the benefits of having a dedicated development team in this piece. We’ll provide a thorough study on how to appoint the ideal group to meet your business’s demands in 2024. The first stage is to ascertain the needs of your project. Making the optimal team configuration choice is equally crucial. We’ll go over every important detail needed to make your project successful.
According to a ManpowerGroup poll, there is a skills shortage worldwide and the pandemic has affected the global labor market. Following France, Romania, and Italy, the US is one of the top few countries that struggles mightily to fill open posts. Manufacturing, sales, IT, logistics, and administration are top industries needing qualified people.
To assist businesses amid rapid technological changes, this article explores benefits, challenges, and best practices.
Benefits of Dedicated Development Teams
Let’s go over the main justifications for your company to consider hiring a specialized development team.
1. Economy of Cost
One of the key justifications for large corporations outsourcing part of their work is the real possibility to reduce operating expenses. Organizations can achieve cost minimization using a dedicated development team strategy in a number of ways, such as:
Supplying charges that are predictable because you will know ahead of time what each expert’s hourly rate is. This will assist you in creating a more accurate budget that will last the whole project.
Ensuring more efficient resource allocation and the full engagement of qualified professionals on pertinent projects. This maximizes the value that may be gained from each team member by reducing downtime and idle periods.
You won’t have to worry about the long-term expenses and responsibilities of employing and training full-time staff because dedicated teams may be readily scaled up or down in accordance with project requirements. This allows you to respond swiftly to changing needs.
2. Proficiency and Specialization
Using a dedicated development team frequently entails reaching out to a wide range of talent from different regions. This makes sure that your development team has all it needs to tackle challenging assignments and projects that can call for specialized knowledge that isn’t easily found within the company or even in your area.
Moreover, dedicated development teams usually keep up with the newest developments in technology. With this flexibility, you won’t need to undergo a significant amount of internal retraining in order to integrate the newest technology into your projects.
3. Ability to Adjust to Change
As needed, you can quickly adjust the team’s size, specialty, and composition within the context of your current business goals. This will free your company from the rigid structure of an internal team and enable it to swiftly modify development goals, introduce new features, or respond to changing market trends. Your business will always have the knowledgeable professionals it needs to handle a variety of markets and legal situations.
4. Participation and Dedication
Unlike some of the other approaches, a dedicated team approach has a shared sense of accountability for project success. Together, in-house and external developers have this shared accountability, which motivates team members to be more involved and dedicated as they strive toward shared goals since they understand how their efforts directly affect the project’s results.
5. No Hustle to Hire and Paycheck Anguish
Software development firms have in-house HR specialists and recruiters. You merely pay the hourly rates, so you don’t need to bother about any HR-related tasks. Payroll, benefits administration, and other administrative work for internal staff might require a lot of time and resources. The administrative load will be reduced by hiring an outside team.
6. Fast Time-to-Market
You are able to modify your strategy when it comes to time to market. To accomplish this, you can work and hire software developers who best fit your needs from the beginning. Teams dedicated to developing software are excellent for startups who want to release their products more quickly.
7. 24/7 Workplace: The Advantage of Time Differences
Diverse time zones might be advantageous since they allow for uninterrupted planning of operations. Rather than posing a problem for cooperation and communication, it offers a tactical benefit that lets companies run around the clock and guarantees steady project advancement. Such an opportunity might be extremely beneficial to industries that depend on continuous operations, such financial institutions, e-commerce platforms, and international customer support services.
Common Challenges in Hiring a Dedicated Development Team
Businesses must overcome a number of obstacles to learn how to hire a dedicated development team with the necessary experience. These obstacles include locating the proper people, making sure that culture fit, managing remote teams, preserving team cohesiveness, and others. Let’s examine the difficulties and ways to get beyond them in more detail:
1. Acquiring Talent
Finding talent is one of the biggest obstacles to creating a development team with experience. Finding personnel with the right knowledge and experience can be a laborious process, requiring time and resources for candidate screening, as there is a global shortage of developers with the necessary abilities.
Businesses that want to overcome this obstacle should use a variety of methods to find talent, including professional networking, social media, and job boards. Gaining access to pre-screened individuals through a partnership with reputable outsourcing or consulting businesses helps streamline the recruitment process.
2. Barriers to Communication
Any development program must have effective communication to be successful. However, working with teams in different time zones or countries can provide special communication challenges because of cultural, linguistic, and working differences. These differences can cause delays, misunderstandings, and ultimately project failure.
Early in the development process, companies should establish communication rules in order to efficiently manage communication obstacles. It entails setting up expectations for responses, channels, cultural training as required, and any required language coaching sessions. Project management tools, daily stand-up meetings, and regularly scheduled video calls can all facilitate better teamwork and communication.
3. Differences in Time Zones
Businesses that collaborate with global development teams may face difficulties due to time zones. When team members are located in different time zones, it may be more challenging to plan meetings, set up work schedules, and respond to inquiries quickly.
Businesses should implement flexible work schedules that accommodate team members who reside in different time zones. In order to facilitate collaboration without the requirement for real-time communication, this may entail reducing working hours, scheduling appointments that coincide with one another, or utilizing asynchronous communications.
4. Cultural Disparities
Cultural differences can have an impact on many aspects of growth, including communication styles, decision-making processes, and workplace ethics. Teams with different cultural backgrounds may experience conflict that needs to be resolved through ongoing discussions or compromise when members are unable to adapt to or comprehend one another’s traditions and conventions.
By organizing cultural exchange events or providing cross-cultural exchange training, businesses can help team members become more sensitive to and conscious of cultural differences and promote an inclusive and cooperative work environment. Teams with similar beliefs and objectives may also find it easier to overcome the disparities between individuals of different backgrounds.
5. Quality Assurance
Businesses that employ committed development teams confront particular difficulties when it comes to quality control protocols. The possibility exists that subpar products will satisfy customer requirements and specifications even in the presence of strong controls and sufficient quality control procedures.
Striving to uphold quality standards requires businesses to apply strict quality assurance practices all the way through the development process. Frequent testing, code reviews, and user acceptability testing are some of these processes that help find and fix errors or inconsistencies quickly. Establishing precise performance indicators and quality measures enables firms to gauge the productivity of their development teams.
6. Protection of Intellectual Property
Businesses hiring software development teams must prioritize protecting intellectual property. This is crucial, especially when collaborating with offshore vendors in different legal systems. Businesses run the danger of losing control over critical data and technologies if they don’t implement enough security measures.
Businesses should create clear contracts outlining ownership, secrecy, and non-disclosure responsibilities in order to reduce these risks. Sensitive information is further protected from unwanted access or exposure by putting strong security measures in place, such as encryption and access limits. In software development collaborations, these actions are crucial for preserving ownership over intellectual property and guaranteeing data security.

In... | 0 | 2024-07-09T12:31:07 | https://dev.to/morrismoses149/how-to-do-regression-testing-2969 | regressiontesting, testgrid | If you are looking for how to do regression testing, then you have landed on the correct article!
In agile, testing must evolve with each sprint, and testers must ensure that new changes do not interfere with the application’s existing functionality. This is referred to as regression testing.
Regression testing ensures that the application’s previous functionality is still functional and that new changes have not introduced new bugs. Regression tests should be used whether there is a small localized change or a more significant change to the software.
Teams must ensure that new code does not conflict with older code and that non-changed code continues to function as expected.
There are frequent build cycles in agile, and the application is updated regularly. As a result, regression testing is critical in agile.
Therefore, a testing team should build the regression suite for successful agile regression testing from the beginning of product development. Along with development sprints, they should continue to improve them.
## Why is Regression Testing Important?
It’s difficult for developers to remember all of the intricate ways new code could interact with existing code when writing code for new features.
Avoiding any potential UI errors slows developers down, making it difficult for agile teams to meet their sprint deadlines. Unfortunately, in many cases, it’s impossible to avoid making mistakes.
However, with a dependable regression test suite, a developer can ensure that a new feature is compatible with all existing functionalities before merging the branch back into the master.
If the tests uncover any new bugs, they can be fixed before joining the branch. As a result, regression testing serves as a safety net, allowing developers to concentrate on the new functionality they’re creating.
Today, most developers would never consider checking in a new code branch without first performing unit testing.
Similarly, when new Rainforest developers start, they can’t believe they’ve ever merged a branch or pushed code to production without first regression testing the UI.
Know more: [Beginner Guide for Automated Regression Testing Tools](https://testgrid.io/blog/beginners-guide-for-automated-regression-testing-tools/)
## When to Do Regression Testing?
It may take some trial and error to find the best cadence for running your entire regression testing suite. However, not every code change is significant enough to warrant running your entire suite.
However, because you’ll be more familiar with the features in the new build and the volume of code you’re testing is smaller, the more frequently you run the suite, the less time it will take to evaluate the results and fix any bugs.
Every time you merge a branch back to master, you should run your full regression suite. If that is not possible, you should still adhere to a few general guidelines.
In the following scenarios, you should always run your regression suite:
- When introducing new features to a product (e.g., adding time-tracking to an invoicing app).
- Following the correction of bugs in an existing feature to ensure that the bug fixes did not introduce new regressions.
- Following the implementation of a significant software upgrade (e.g., switching to the latest version of Ruby on Rails).
- Before deploying code to production.
## Best Practices for Regression Testing
### 01 Don’t aim for 100% automation
Regardless of how advanced the test infrastructure is, 100% automation is not possible. At the very least, test scripts must be written, and human testers must validate the results.
In the best-case scenario, 70 to 90 percent automation is achievable because a certain number of test cases will result in false positives/negatives and are therefore unsuitable for regression testing.
### 02 Concentrate on the most vulnerable areas of software
Most developers and testers are familiar enough with their software to identify the areas/functions/features that are most likely to be impacted by changes in each sprint.
Additionally, user-facing functions and critical backend issues must be tested regularly. As previously stated, the collaborative approach to regression testing in agile development aids in this because it includes developers.
### 03 Choose Automation
Automation is a must for accelerating regression tests for Agile sprints. Begin with an automated regression test script, then modify it with each new feature.
As a result, QAs must focus on making incremental changes with each sprint rather than running the tests.
### 04 Know About The Needs of Testers
Keep in mind that testers will need to invest some manual testing effort in the early stages – studying product flow, software logic, UI changes, and so on.
Automated regression tests are best introduced after the software has been developed and some significant changes have already been implemented. Regression tests should also be interspersed with manual verifications to check for false positives or negatives.
## Automated and Regression Testing:
**Fast-running**: Because automated tools can perform certain tasks faster than humans, selecting the right problems to solve with an automated tool can increase the speed with which they are completed. When implementing an automated tool or framework, anything that is highly repetitive and easily automated should be prioritized.
**Parallel activities**: Running automated tools on machines other than the team’s systems allows them to run in the background while other tasks are completed. However, this does not necessarily imply that your team can perform more regression testing in the same amount of time. Plan ahead of time and consider your approach to automation in your regression testing strategy.
**Targeted feedback**: You can use automated tools to work with parts of the system that might be trickier to get to when testing normally. This allows automated tools to potentially give feedback on very specific parts of the product, which will help you target additional regression testing with greater accuracy.
## Regression Testing Methods:
Re-testing everything entails rerunning all existing tests against the new codebase. This would isolate regressions if the tests were well designed. This method, however, is resource-intensive and may not be feasible for a large codebase.
Selective re-testing is sometimes possible to identify a subset of your existing tests that can address all or nearly all of your codebase’s “moving parts.” It is then sufficient to rerun that specific set to find regressions throughout the codebase.
Prioritized re-testing—applicable to large codebases. Priority tests focus on code paths, user actions, and areas of functionality that are likely to contain bugs. After these tests have been completed, you can proceed to the next set of tests.
## Challenges of Regression Testing:
### 01 There are too many changes
Agile methods incorporate stakeholder feedback after each sprint, which is a good strategy for avoiding significant changes later on.
However, if management and users propose too many changes to product requirements, it may be necessary to rework regression test scripts from scratch in the middle of a project.
### 02 Expanding test suites
As new features are added, the scope of regression tests grows with each sprint. As a result, suits can quickly become unwieldy and unmanageable with sufficient automation and team structure.
### 03 Pressures of test case maintenance
As test suites grow in size, they must also be maintained, examined, and updated after each sprint. Obsolete tests must be removed, and new tests must be created and added. This can be time-consuming if a project necessitates a large number of iterations.
### 04 Communication needs
Testers must maintain constant contact with developers, business analysts, users, and other stakeholders. They require this to become acquainted with the features being developed and user expectations. This may be difficult to achieve and maintain for small teams in particular.
### 05 Necessities of skills, knowledge, and frameworks
Automation necessitates testers with technical skills and extensive knowledge of test automation frameworks such as Selenium, Appium, multiple programming languages, and experience running tests in various environments.
Consolidating a team of such individuals may pose financial and time-related challenges for teams just getting started with Agile development.
Selenium for Regression Testing:
Selenium is an open-source suite of web testing tools. It is now the most popular tool for web testing on both desktop and mobile devices.
Testers can ensure that their web app does not break by running Selenium scripts against web browsers such as Chrome, Firefox, and Safari.
Selenium can be used to perform a wide range of tests, including user interface testing, sanity testing, and regression testing.
Using Selenium for regression testing assists developers in detecting flaws in their web applications before they affect customers. Strategically, such tests aid developers in the modification of code and the introduction of new features.
Selenium regression testing automation frees up testers to focus on problem-solving or more complex types of tests. Furthermore, automation ensures that tests are run methodically and efficiently and that they are not subject to human error.
## How To Do Regression Testing In Selenium?
### 01 Specify the Requirements
Concentrate on the product and define what is critical for you, the product team, your customers, and other stakeholders.
- Consider whether you should test only one application or several.
- When will I run the regression tests – at the end of each sprint or only after significant changes?
- What constitutes a significant change?
- When do I need to achieve complete regression coverage?
### 02 Examine Possible Use Cases
Use cases will assist you in understanding exactly what you are up against. Begin with a logical description of the tests you intend to cover. Don’t forget about difficult scenarios so that you’re fully prepared.
03 Establish a baseline
A proper baseline from which to build will allow us to understand where we are.
### 04 Select Your Technology Stack
Choosing your tech stack entails selecting a scripting language, a testing platform, and scaling tools. Consider the expected outcomes, inbound and outbound data, and what needs to be covered.
Aside from the standard tapping and scrolling, it would help if you also prepared the following for mobile web testing.
### 05 Face ID / Fingerprint ID
- Network condition simulation (loss of connectivity, insufficient network coverage).
- Location simulation.
- Image injection, such as scanning barcodes or QR codes.
- Injection of audio.
- SIM-cards
- Complete control over system settings (i.e., Offline mode, Low battery mode).
### 06 Make Tests
Obtain a critical mass of tests and incorporate them into the automation pattern. All of these tests must be atomic and by the overall plan of action. This means they should be able to run independently without relying on other tests.
## Conclusion:
Regression Testing ensures the least amount of downtime while keeping costs low. Our Regression Testing suite provides that new features or enhancements to the application have no unintended consequences for the application’s current quality.
Our test teams thoroughly comprehend and analyze the effects of changes made to the test environment and application.
Changes to the test environment can include deployment configuration changes, database updates, and operating system updates, to name a few. Bug fixes, new functionality, functionality enhancements, integrations, patches, and interfaces are all examples of changes to the application.
Regression testing is unquestionably necessary, particularly after introducing new features or changes to software code. Still, it is not recommended to perform regression testing manually because it consumes a significant amount of time and resources and may be inaccurate.

Regarding information, they have a website where any individual can read clients’ reviews and feedback that they post. Or it can be by recommendations gotten from other patients and from friends, family or any other person you know. Positive feedback and a good clinic reputation in the community mean that people have had satisfactory experiences with the clinic. This will help you locate the <strong style="mso-bidi-font-weight: normal;">best dentist doctor near me</strong>.</span></p>
<p style="text-align: justify;"><span style="mso-spacerun: yes;"> </span></p>
<h2><a></a><strong style="mso-bidi-font-weight: normal;"><span><span style="mso-spacerun: yes;"> </span>2. Dentist's Qualifications and Experience: </span></strong></h2>
<p style="text-align: justify;"><span style="mso-spacerun: yes;"> </span></p>
<p style="text-align: justify;"><span>Another tip that you should consider is to ensure that you take your time to review the education and the working experience of the dentists performing the services at the clinic. Also, the clients should visit qualified dentists with all the requisite authorization to conduct dental operations. For any special treatments, including orthodontic, surgery, or cosmetic work, book with a dentist doctor who is well qualified and licensed near you. </span></p>
<p style="text-align: justify;"><span style="mso-spacerun: yes;"> </span></p>

<p style="text-align: justify;"><span style="mso-spacerun: yes;"> </span></p>
<p style="text-align: justify;"><span>You need to discover whatever services are offered at the clinic for the teeth. Thus, it is recommended that a good tooth clinic should offer diverse services ranging from simple ones like checkups and cleaning, binding, and filling to more complex treatments such as whitening and reshaping the teeth, root canal treatment, crowning, and implant. Doing this will also give you the opportunity to receive all necessary treatments from one center. </span></p>

1,917,326 | Best Practices for Creating Container Images | Imagine running 100s of microservices in production without knowing the dos and don'ts around... | 0 | 2024-07-10T05:34:18 | https://devtron.ai/blog/best-practices-for-creating-container-image/ | docker, kubernetes, devops, cloud | Imagine running 100s of microservices in production without knowing the dos and don'ts around creating container images. It’d be chaotic. You don’t want to spend hours building your container images and also you would not want to deploy images with vulnerabilities.
Containerization has become a cornerstone of modern software development and deployment, offering numerous benefits in terms of scalability, consistency, portability, and efficiency. One of the key elements in the container ecosystem is the creation of optimized and secure container images. In this blog, we will delve into the best practices for creating container images to help you build lightweight, reliable, and most importantly secure images to make sure that your image is production-ready.
## Hacks for optimizing container images
Creating a container image and optimizing it are two sides of a coin. For container creation, there are different ways which might involve writing a declarative Dockerfile or maybe using cloud-native buildpacks depending upon the use-cases. When it comes to optimization, it's true for all types of images being created. Here are some of the methods that can be used to optimize your container image and ensure the uptime of your applications.
## 1) Docker Hub image pull rate limit
In cases when you are dealing at scale, for instance - running a daemon set that is pulling its docker image from Docker Hub on a 100-node cluster at a time. In such scenarios, you’ll frequently face issues of rate limit. For example: You have reached your pull rate limit
Now, How do we deal with it?
i) Look for an alternative container registry where your helm chart’s public image could be available for instance, quay or ghcr. In these container registries, there aren't any image pull limits. [Recommended]
ii) Keep the image in your organization’s container registry like ECR, ACR, etc. Make sure that the node has appropriate permissions for the pod to inherit. There would be an overhead to keep updating the image in case you are using your private registries for public helm charts.
> Note: In the case of Docker Hub, 100 pull requests per 6 hours for anonymous users on a free plan. Enforced based on your IP Address. And 200 pull requests per 6 hours for authenticated users on a free plan.
## 2) Use Build Contexts
Avoid building your docker images like this - Docker build -t <tag> . , unless you want to set the context as the current working directory. Here period (.) means context as the current working directory.
Let’s say you have two directories: i) app and ii) consumer having the app’s code and consumer’s code respectively within the same repository then your build context should be app/ and consumer/ respectively. This would be helpful in scenarios where you are using COPY . . in Dockerfile as you will only be copying content from a specified folder instead of a complete repository and hence it’ll decrease time.
PS: It is super easy to configure the build context if you are building your Dockerfile from Devtron
## 3) Multi-architecture Builds
If you have multi-architecture nodes in your cluster, i.e., ARM-based and AMD-based machines, then you will need to set the –platform flag to specify the target platform. By default, you can only build for a single platform at a time. With IDPs like Devtron, you can easily build container images for multiple architectures at your fingertips.
## 4) Implement Image Caching
A container image has multiple different layers. Imagine the size of container image is in Gegabytes. Everytime you build an image, it will start from the initial layers and build each and every layer. Those layers comes from the steps given in your dockerfile or the steps involved in building the image. Once you build your image, in subsequent builds, it will again create all those layers which will increase the time to build. To optimise the build time, it is highly recommended to implement caching mechanism so that next time when a new image will be build, it will leverage the cache of previous build for all those steps which were not changed and using the existing cache, build time will be reduced.
## 5) Golden Image Creation
It is one of the widely recommended practices to have golden images for your application. If all of your applications require a certain package, you don’t want to install it at run time; every time instead you can include it in the golden image and use that image as a bage image for your container images. It’ll save a lot of time.
Techniques for optimizing container image
Now let's discuss some of the common techniques that can help you optimize your container images.
## 1) Multi-Stage Builds
Multi-stage builds enable you to create a final image that only includes the runtime dependencies and necessary artifacts. Unnecessary build tools, libraries, and intermediate files are discarded in subsequent stages, resulting in smaller image sizes. This reduction in size leads to faster image pulls and deployments, optimizing resource utilization. For applications such as Java which uses maven/gradle files, a multi-stage dockerfile can be helpful.
## 2) Minimize Layers
Concatenate RUN commands to make your Dockerfile more readable and create fewer layers. Fewer layers mean a smaller container image. Each RUN statement in the Dockerfile creates a layer that gets cached. Concatenating reduces the number of layers.
## 3) Use Lightweight Images
Always choose the smallest base images that do not contain the complete or full-blown OS with system utilities installed. You can install the specific tools and utilities needed for your application in the Dockerfile build. This will reduce possible vulnerabilities and the attack surface of your image.
## Creating a Secure Container Image
Making sure the container image is secure and ready to be used in production is another important aspect and a part of DevSecOps practices. Here are some of the practices that can be incorporated for building a secure image.
## 1) Environment Variables
Never inject environment variables within your container image. Embedding env variables within your container image means you are hardcoding them within the image. This way the image would not be generic to use across various microservices. So always use configMaps and Secrets to store env variables and credentials.
## 2) Vulnerability Scanning
Never deploy images with critical CVEs into production as this way you would be an easy target for hackers to hack into your application. Make sure to integrate vulnerability scanning tools in your pipeline so that you ship an application without vulnerabilities. On top of vulnerability scanning, having governance policies such as automatically blocking the image with critical CVEs can help you strengthen the pipeline.
Check out [this blog to understand more about vulnerability scanning of container images using Trivy and how Devtron integrates with it](https://devtron.ai/blog/improve-security-with-vulnerability-scanning-by-trivy/).
## 3) Non-root User
By default, Docker containers run as the root user, which can pose security risks if the container gets compromised. In such cases, the hacker would have root access to your host and could bring the entire node down. So always ensure that your images run as non-root by defining USER in your Dockerfile.
## 4) Avoid using <image>:latest
The latest image tag for any public repository might bring in unexpected bugs. So it’s always recommended to specify a specific version instead of the latest.
## Conclusion
Creating high-quality container images is a crucial aspect of modern application development and deployment. By following these best practices, you can produce container images that are optimized, secure, and well-suited for deployment in various environments. Well-crafted images contribute to faster deployment, improved security, better resource utilization, and enhanced application performance, setting the foundation for successful container-based workflows.

1,917,328 | How to build a Todo app with Typescript | In this blog post, we will build a to-do app using typescript. The app allows users to add, delete,... | 0 | 2024-07-09T12:47:20 | https://p-blog.online/668d291bc61f9d5a320a0622? | webdev, typescript, beginners | 
In this blog post, we will build a to-do app using typescript. The app allows users to add, delete, and update tasks, and users can mark completed tasks or unmark them. We will follow the Model, View, Controller (MVC) design pattern. Here is the link for the app [Todo app with typescript](https://6683cca0885c60255f7d5361--beautiful-madeleine-23be54.netlify.app/). We will use `vite` to quickly set up the typescript project. Let's get started!
## Setup typescript project using `vite`
Run the following command in the terminal
```
npm create vite@latest
```
It will ask you to enter the project name. we can say `Typescript-todo-app`. We will be using just typescript in this project so, in `Select a framework` prompt we need to choose `Vanilla`. In the next prompt, we need to choose `TypeScript`. Then, Vite will setup the project for us. To run the project run the following command in the terminal:
```
cd Typescript-todo-app
npm install
npm run dev
```
This will run the typescript-configured project. We can delete all unwanted files. I have used `bootstrap` and `uuid` to generate a unique `id` for each task item. So, let's install these packages and import them into the `main.ts` file
```
npm install bootstrap uuid
```
```
import "bootstrap/dist/css/bootstrap.min.css";
import { v4 as uuid } from "uuid";
```
Our project files and folders tree looks like the following:
```
Typescript-todo-app
├── public
├── src
│ ├── controller
│ │ └── TaskListController.ts
│ ├── model
│ │ ├── TaskItem.ts
│ │ └── TaskList.ts
│ ├── view
│ │ └── TaskListView.ts
│ └── main.ts
├── index.html
└── tsconfig.json
```
## Creating model for TaskItem and TaskList
### TaskItem
In the `model` folder create a file `TaskItem.ts`. In this file, we will define a model for a single task. A single task item will have the following properties
* Unique `id` for that we will be using `uuid` library
* `task` actual description of the task itself
* `completed` a boolean value indicating whether the task is completed or not, which value will be `false` by default and can be changed latter
```
export interface SingleTask {
id: string;
task: string;
completed: boolean;
}
export default class TaskItem implements SingleTask {
constructor(
private _id: string = "",
private _task: string = "",
private _completed: boolean = false
) {}
get id(): string {
return this._id;
}
set id(id: string) {
this._id = id;
}
get task(): string {
return this._task;
}
set task(task: string) {
this._task = task;
}
get completed(): boolean {
return this._completed;
}
set completed(completed: boolean) {
this._completed = completed;
}
}
```
Here, first, we have defined an `interface` for a `SingleTask`. The interface provides the syntax for classes to follow. Any classes implementing a particular interface have to follow the structure provided by that interface.
Then, we have defined a `class` named `TaskItem` that implements the `SingleTask` interface. This means that the `TaskItem` class has to have all properties defined in the interface.
The constructor allows us to set the value for `id`, `task`, and `completed` when creating a new `TaskItem` instance. Plus, we've also defined getter and setter methods for each property. Getters allow us to retrieve the current value of the property, while setters ensure that any changes to the property are handled appropriately. We will see these in action while editing tasks and toggling task status.
### TaskList
`TaskList.ts` will be responsible for managing the collection of TaskItem which includes retrieving tasks, adding, deleting, updating tasks, saving collection of tasks in `localStorage`, loading tasks from `localStorage`, and filtering tasks.
```
import TaskItem from "./TaskItem";
interface AllTask {
tasks: TaskItem[];
load(): void;
save(): void;
clearTask(): void;
addTask(taskObj: TaskItem): void;
removeTask(id: string): void;
editTask(id: string, updatedTaskText: string): void;
toggleTaskChange(id: string): void;
getTaskToComplete(): TaskItem[];
getCompletedTask(): TaskItem[];
}
export default class TaskList implements AllTask {
private _tasks: TaskItem[] = [];
get tasks(): TaskItem[] {
return this._tasks;
}
load(): void {
const storedTasks: string | null = localStorage.getItem("myTodo");
if (!storedTasks) return;
const parsedTaskList: {
_id: string;
_task: string;
_completed: boolean;
}[] = JSON.parse(storedTasks);
parsedTaskList.forEach((taskObj) => {
const newTaskList = new TaskItem(
taskObj._id,
taskObj._task,
taskObj._completed
);
this.addTask(newTaskList);
});
}
save(): void {
localStorage.setItem("myTodo", JSON.stringify(this._tasks));
}
clearTask(): void {
this._tasks = [];
localStorage.removeItem("myTodo");
}
addTask(taskObj: TaskItem): void {
this._tasks.push(taskObj);
this.save();
}
removeTask(id: string): void {
this._tasks = this._tasks.filter((task) => task.id !== id);
this.save();
}
editTask(id: string, updatedTaskText: string): void {
if (updatedTaskText.trim() === "") return;
const taskToUpdate = this._tasks.find((task) => task.id === id);
if (!taskToUpdate) return;
taskToUpdate.task = updatedTaskText;
this.save();
}
toggleTaskChange(id: string): void {
const taskToUpdateChange = this._tasks.find((task) => task.id === id);
if (!taskToUpdateChange) return;
taskToUpdateChange.completed = !taskToUpdateChange.completed;
this.save();
}
getCompletedTask(): TaskItem[] {
const completedTask = this._tasks.filter((task) => task.completed);
return completedTask;
}
getTaskToComplete(): TaskItem[] {
const taskToComplete = this._tasks.filter((task) => !task.completed);
return taskToComplete;
}
}
```
In the above code, first, we have imported the `TaskItem` class and then defined an interface `AllTask`. This interface outlines the methods a `TaskList` class should implement to manage tasks.
Inside the `TaskList` class, we have private property `_tasks` which holds an array of `TaskItem`.
The `load` method attempts to retrieve a serialized list of tasks from local storage with the key "`myTodo`".
If data is found, it parses the JSON string back into an array of objects with properties matching TaskItem's structure. It then iterates through the parsed data and creates new `TaskItem` objects, adding them to the internal `_tasks` array using the `addTask` method.
The `save` method serializes the current `_tasks` array into a JSON string and stores it in `localStorage` with the key "`myTodo`".
`clearTask`: This method removes all tasks from the internal list and clears the associated data from localStorage.
`addTask`: This method adds a new `TaskItem` object to the beginning of the internal `_tasks` array and calls the save method to persist the change.
`removeTask`: This method takes an `id` as input and filters the `_tasks` array, keeping only tasks where the id property doesn't match the provided id. It then calls save to persist the change.
`editTask`: This method takes an `id` and a `updatedTaskText` as input. It first checks if the `updatedTaskText` is empty (trimmed) and returns if so.
It then finds the task with the matching `id` using the find method. If no task is found, it returns. Finally, it updates the `task` property of the found `task` object with the provided `updatedTaskText` and calls `save` to persist the change.
`toggleTaskChange`: This method takes an id as input. It finds the task with the matching `id` and flips the value of its completed property (i.e., marks it as completed if pending or vice versa). Finally, it calls `save` to persist the change.
`getCompletedTask`: This method returns an array containing only the tasks where the completed property is set to true (completed tasks).
`getTaskToComplete`: This method returns an array containing only the tasks where the completed property is set to false (pending tasks).
## Creating a controller for TaskList
Now, let's create a file named `TaskListController.ts` inside the `controller` folder. This class acts as a bridge between `view` and `modal` as it interacts with `model` based on user interaction through the `view` component which we will create later.
First of all, let's import `TaskItem` and `TaskList` classes from the `model` and define an interface for `TaskListController`.
```
import TaskItem from "../model/TaskItem";
import TaskList from "../model/TaskList";
interface Controller {
getTaskList(): TaskItem[];
addTask(newTask: TaskItem): void;
deleteTask(taskId: string): void;
editTask(taskId: string, updatedTaskText: string): void;
loadTask(): void;
clearTask(): void;
saveTask(): void;
toggleTaskChange(taskId: string): void;
getPendingTask(): TaskItem[];
getCompletedTask(): TaskItem[];
}
```
Now, create a class `TaskListController` that implements the `Controller` interface. This ensures the class provides all the functionalities defined in the interface.
```
export default class TaskListController implements Controller {
private _taskList: TaskList = new TaskList();
constructor() {
this.loadTask();
}
getTaskList(): TaskItem[] {
return this._taskList.tasks;
}
addTask(newTask: TaskItem): void {
this._taskList.addTask(newTask);
}
deleteTask(taskId: string): void {
this._taskList.removeTask(taskId);
}
editTask(taskId: string, updatedTaskText: string): void {
this._taskList.editTask(taskId, updatedTaskText);
}
getCompletedTask(): TaskItem[] {
const completedTask = this._taskList.getCompletedTask();
return completedTask;
}
getPendingTask(): TaskItem[] {
const pendingTask = this._taskList.getTaskToComplete();
return pendingTask;
}
clearTask(): void {
this._taskList.clearTask();
}
loadTask(): void {
this._taskList.load();
}
saveTask(): void {
this._taskList.save();
}
toggleTaskChange(taskId: string): void {
this._taskList.toggleTaskChange(taskId);
}
}
```
Inside the class, a private property `_taskList` is declared and initialized with a new instance of the `TaskList` class. This `_taskList` object handles the actual storage and manipulation of tasks.
The constructor gets called whenever a new `TaskListController` object is created.
Inside the constructor, it calls the `loadTask` method, to retrieve any previously saved tasks from persistent storage and populate the internal `_taskList` object.
The class defines several methods each of these methods simply calls the corresponding method on the internal `_taskList` object. For instance, `getTaskList` calls t`his._taskList`.tasks to retrieve the task list, `addTask` calls `this._taskList`.
By delegating the work to the `_taskList` object, the TaskListController acts as a facade, providing a convenient interface for interacting with the task management functionalities.
## Creating a view for TaskList
Let's create a file named `TaskListView.ts` inside a folder `view`. We will create a class `HTMLTaskListView`, which is responsible for rendering the tasks on the web page and managing user interactions. First, let's create an interface for this class.
```
import TaskItem from "../model/TaskItem";
import TaskListController from "../controller/TaskListController";
interface DOMList {
clear(): void;
render(allTask: TaskItem[]): void;
}
```
In the above interface `DOMList`, we only have two methods. These two methods will be public and are responsible for rendering tasks and clearing all tasks.
Now let's look at `HTMLTaskListView` class.
```
export default class HTMLTaskListView implements DOMList {
private ul: HTMLUListElement;
private taskListController: TaskListController;
constructor(taskListController: TaskListController) {
this.ul = document.getElementById("taskList") as HTMLUListElement;
this.taskListController = taskListController;
if (!this.ul)
throw new Error("Could not find html ul element in html document.");
}
clear(): void {
this.ul.innerHTML = "";
}
private createTaskListElement(task: TaskItem): HTMLLIElement {
const li = document.createElement("li") as HTMLLIElement;
li.className = "list-group-item d-flex gap-3 align-items-center";
li.dataset.taskId = task.id;
const checkBox = this.createCheckBox(task);
const label = this.createLabel(task);
const editTaskInput = this.createEditTaskInput();
const [saveButton, editButton] = this.createEditAndSaveButton(
editTaskInput,
label,
task
);
const deleteButton = this.createDeleteButton(task);
li.append(
checkBox,
editTaskInput,
label,
editButton,
saveButton,
deleteButton
);
return li;
}
private createCheckBox(task: TaskItem): HTMLInputElement {
const checkBox = document.createElement("input") as HTMLInputElement;
checkBox.type = "checkbox";
checkBox.checked = task.completed;
checkBox.addEventListener("change", () => {
this.taskListController.toggleTaskChange(task.id);
});
return checkBox;
}
private createEditTaskInput(): HTMLInputElement {
/// input field to edit task
const editTaskInput = document.createElement("input") as HTMLInputElement;
editTaskInput.hidden = true;
editTaskInput.type = "text";
editTaskInput.className = "form-control";
return editTaskInput;
}
private createLabel(task: TaskItem): HTMLLabelElement {
const label = document.createElement("label") as HTMLLabelElement;
label.htmlFor = task.id;
label.textContent = task.task;
return label;
}
private createEditAndSaveButton(
editTaskInput: HTMLInputElement,
label: HTMLLabelElement,
task: TaskItem
): HTMLButtonElement[] {
const saveButton = document.createElement("button") as HTMLButtonElement;
saveButton.hidden = true;
saveButton.className = "btn btn-warning btn-sm";
saveButton.textContent = "Save";
const editButton = document.createElement("button") as HTMLButtonElement;
editButton.className = "btn btn-success btn-sm";
editButton.textContent = "Edit";
saveButton.addEventListener("click", () => {
const updatedTaskText = editTaskInput.value;
task.task = updatedTaskText;
this.taskListController.editTask(task.id, updatedTaskText);
saveButton.hidden = true;
editButton.hidden = false;
editTaskInput.hidden = true;
this.render(this.taskListController.getTaskList());
});
editButton.addEventListener("click", () => {
saveButton.hidden = false;
editTaskInput.hidden = false;
editTaskInput.value = task.task;
label.innerText = "";
editButton.hidden = true;
});
return [saveButton, editButton];
}
private createDeleteButton(task: TaskItem): HTMLButtonElement {
const deleteButton = document.createElement("button") as HTMLButtonElement;
deleteButton.className = "btn btn-primary btn-sm";
deleteButton.textContent = "Delete";
deleteButton.addEventListener("click", () => {
this.taskListController.deleteTask(task.id);
this.render(this.taskListController.getTaskList());
});
return deleteButton;
}
render(allTask: TaskItem[]): void {
this.clear();
allTask.forEach((task) => {
const li = this.createTaskListElement(task);
this.ul.append(li);
});
}
}
```
### Constructor and Initialization
The constructor initializes the HTMLTaskListView class. It sets up essential properties and ensures that the necessary DOM elements are available.
```
constructor(taskListController: TaskListController) {
this.ul = document.getElementById("taskList") as HTMLUListElement;
this.taskListController = taskListController;
if (!this.ul)
throw new Error("Could not find html ul element in html document.");
}
```
The properties `taskListController` is an instance of `TaskListController` that manager the tasks and `ul` is a reference to the HTML unordered list element where tasks will be displayed.
### Clearing the TaskList
The `clear` method removes all child elements from the ul element, effectively clearing the task list displayed on the webpage.
```
clear(): void {
this.ul.innerHTML = "";
}
```
### Creating Task List Elements
* `createTaskListElement(task: TaskItem): HTMLLIElement` creates an individual task item element (li) and appends various components such as checkboxes, labels, edit inputs, and buttons and we have methods for each of these components.
* `createEditTaskInput(): HTMLInputElement` generates an input field used for editing the task description, initially hides the input field, and will show when the user clicks on `Edit` button.
* `createLabel(task: TaskItem): HTMLLabelElement` creates a label element to display the task description.
* `createEditAndSaveButton(editTaskInput: HTMLInputElement, label: HTMLLabelElement, task: TaskItem): HTMLButtonElement[]` generates buttons for editing and saving task descriptions and manages their visibility and actions.
* `createDeleteButton(task: TaskItem): HTMLButtonElement` creates a delete button and when clicked removes tasks from the list.
### Rendering the Task List
`render` method takes an array of `TaskItem` representing all tasks to be displayed, clears the current task list, and populates it with the provided tasks.
## Creating an add task form
So far, we have created a Model, View, and Controller for our Todo app. Now, it's time to look into `index.html` page. Where we will create a form where users can write a task and add it to our to-do app plus we will create buttons to show completed tasks, tasks to complete, and clear all tasks.
```
<body>
<div class="container" style="max-width: 800px;">
<h2>Todo list app with TypeScript</h2>
<form class="m-3" id="todo-form">
<div class="form-group p-2 d-flex">
<input name="new-todo" class="form-control" type="text" id="new-todo" placeholder="Add new todo"/>
<button type="submit" class="btn btn-primary mx-2">Add</button>
</div>
</form>
<section style="max-width: 600px;">
<div class="btn-group my-2" role="group" aria-label="Basic mixed styles example">
<button type="button" id="all-task" class="btn btn-danger">All Tasks</button>
<button type="button" id="completed-task" class="btn btn-warning">Completed Task</button>
<button type="button" id="task-to-complete" class="btn btn-success">Task To Complete</button>
<buttonc type="button" id="clear-btn" class="btn btn-secondary">Clear All</button>
</div>
<ul id="taskList" class="list-group">
</ul>
</section>
</div>
</body>
```
## Connecting Model, View, Controller
In, MVC architecture, View captures user interaction such as new task is added, the delete button is clicked, and sends them to the Controller. Then, the Controller acts as an intermediary between the Model and the View. It updates the Model such as adding a new task to the task list, deleting a task from the list, or updating a single task. We have already created a Model, View, and Controller. Now let's connect them together.
In `main.ts` file let's import the required classes and initialize Controller and View.
### Importing and Initializing the Controller and View
```
import TaskItem from "./model/TaskItem";
import TaskListController from "./controller/TaskListController";
import HTMLTaskListView from "./view/TaskListView";
const taskListController = new TaskListController();
const taskListView = new HTMLTaskListView(taskListController);
```
* `taskListController`: An instance of `TaskListController` that manages the task data and business logic.
* `taskListView`: An instance of `HTMLTaskListView` that takes the taskListController as an argument. This view will handle rendering tasks on the webpage.
### Accessing DOM Elements
```
const todoForm = document.getElementById("todo-form") as HTMLFormElement;
const clearBtn = document.getElementById("clear-btn") as HTMLButtonElement;
const showCompletedTask = document.getElementById("completed-task") as HTMLButtonElement;
const showTaskToComplete = document.getElementById("task-to-complete") as HTMLButtonElement;
const showAllTask = document.getElementById("all-task") as HTMLButtonElement;
```
* `todoForm`: The form where new tasks are added.
* `clearBtn`: The button to clear all tasks.
* `showCompletedTask`: The button to filter and display completed tasks.
* `showTaskToComplete`: The button to filter and display pending tasks.
* `showAllTask`: The button to display all tasks.
### Initializing the Application
```
const initApp = () => {
const allTask = taskListController.getTaskList();
taskListView.render(allTask);
};
initApp()
```
* `initApp`: A function that initializes the application by fetching all tasks from the controller and rendering them using the view. We have called the `initApp` function right away to ensure that the task list is rendered when the application loads.
### Adding a New Task
```
if (todoForm) {
todoForm.addEventListener("submit", (e) => {
e.preventDefault();
const formData = new FormData(todoForm);
const todoValue = formData.get("new-todo") as string;
if (todoValue === null || todoValue?.toString().trim() === "") return;
const newTask = new TaskItem(uuid(), todoValue.trim());
taskListController.addTask(newTask);
initApp();
todoForm.reset();
});
}
```
On submission, `todoForm` will do the following:
1. Prevent the default form submission behavior.
2. Extract the new task description from the form.
3. Validate the task description (non-empty and non-null).
4. Create a new TaskItem with a unique ID and the trimmed task description.
5. Add the new task to the controller.
6. Reinitialize the application to render the updated task list.
7. Reset the form.
### Clearing All Tasks
```
clearBtn.addEventListener("click", () => {
taskListController.clearTask();
taskListView.clear();
});
```
### Showing Completed Tasks
```
showCompletedTask.addEventListener("click", () => {
const completedTask = taskListController.getCompletedTask();
taskListView.render(completedTask);
});
```
### Showing Tasks to Complete
```
showTaskToComplete.addEventListener("click", () => {
const taskToComplete = taskListController.getPendingTask();
taskListView.render(taskToComplete);
});
```
## Conclusion
In Conclusion, our todo application built using the MVC architecture demonstrates a robust and maintainable structure for managing tasks. By breaking down the responsibilities into distinct components—Model, View, and Controller—the application achieves a clear separation of concerns, which enhances both scalability and maintainability. | pmadhav82 |

Did you know that [SharePoint workflows](https://www.webtualglobal.com/best-sharepoint-development-company-in-usa/) can drastically reduce the time and effort needed for your business processes? Recent statistics reveal that companies using SharePoint workflows see a 30% reduction in project turnaround time and a 25% increase in productivity. Essentially, workflows act like tiny superheroes, helping you streamline daily tasks and enhance overall efficiency.
**What is SharePoint Workflow?**
Gone are the days of relying on SharePoint Designer 2010 for workflows. With Microsoft’s latest tool, Power Automate, you can create even more powerful workflows within your Microsoft 365 environment. [Power Automate](https://www.webtualglobal.com/best-power-automation-development-company-in-usa/) has become the recommended solution for workflow development, as Microsoft has stopped updating SharePoint Designer since 2013.
If you want to leverage the latest workflow technology, it’s time to transition from the old to the new with Microsoft Power Automate. Let’s explore how SharePoint workflows can transform your work processes.
**Use Cases for SharePoint Workflow**
**Leave Requests Made Easy**: Imagine submitting your vacation time online and having it automatically routed to your boss for approval. That’s the power of a SharePoint workflow, complete with reminders to ensure timely approval.
**Streamlined Invoicing**: No more manually sending invoices to different departments for approval. A SharePoint workflow automates the process and stores everything in a central location, eliminating headaches.
**Effortless Feedback Collection**: Create a SharePoint workflow to send out surveys and collect feedback from your customers. You’ll get the information you need without any hassles.
**Enhanced Document Functionality**: With SharePoint workflows, your documents can do more than just sit in a folder. Set up workflows to automatically perform tasks like sending email notifications or updating statuses when files are changed or uploaded.
**Multiple Approvals Made Simple**: Approval processes can quickly become complicated, but with a SharePoint workflow, you can easily set up multilevel approvals. Requests are routed sequentially, and if not approved in time, they get automatically escalated.
**Types of SharePoint Workflow**
**Approval Workflow**: This workflow routes a document or item to one or more people for approval. It can be triggered manually or automatically when an item is created in a SharePoint list or a document is uploaded to a library.
**Use Case**: Invoices sent to the accounting department may need approval before payment. An approval workflow automates this chain, routing the invoice to the appropriate managers before final approval and uploading to the library.
**Notification Workflow**: This workflow sends an email notification to the relevant person when something important happens, such as the approval of a document or a status change. It speeds up processes and prevents delays.
**Use Case**: After completing a major project, your tech team marks it as complete in the SharePoint list. You receive an instant notification, allowing you to update your client promptly.
**Automation Workflow**: These workflows perform tasks automatically when certain conditions are met, such as moving an invoice to the correct folder once it’s approved.
**Use Case**: When you approve an invoice, an automation workflow can move it to the designated folder automatically, saving you time and effort.
**Custom Workflow**: These workflows can be tailored to meet your business’s unique needs by combining different types of workflows.
**Use Case**: To approve an invoice and notify the accounting department, use an approval workflow and a notification workflow. Customize the workflow to suit your organization’s specific requirements.
**Benefits of Using SharePoint Workflows**
**Time-Saving and Increased Productivity:** SharePoint workflows automate mundane tasks, freeing up your time to focus on innovative ideas and business growth.
**Accuracy and Consistency**: Automating tasks ensures they are performed consistently, reducing errors and keeping everyone aligned.
**Enhanced Collaboration**: SharePoint workflows facilitate document sharing and tracking, allowing teams to work together more effectively without constant check-ins.
**Clear Visibility**: Workflows provide a transparent view of task and document progress, helping you stay informed and make better decisions.
**Flexibility**: Customize workflows to fit your needs, choosing the types of workflows, the people involved, and the actions taken at each step.
**Conclusion**
SharePoint workflows offer numerous benefits to any organization aiming to streamline processes and enhance collaboration. From managing leave requests to automating document approvals, workflows can help businesses operate more efficiently and effectively. By embracing workflow automation, companies can reduce risks, save time and money, and achieve greater success.
So, if you’re ready to elevate your business processes, it’s time to explore the power of SharePoint workflows.
**Note**
SharePoint Designer 2010 workflows have been retired since August 1, 2020, for new tenants and removed from existing tenants on November 1, 2020.

1,917,332 | TailwindCSS Text. Free UI/UX design course | Text At the end of the previous lesson, we finally managed to place the Call to action... | 25,935 | 2024-07-09T15:00:00 | https://dev.to/keepcoding/tailwindcss-text-free-uiux-design-course-4p6f | tailwindcss, learning, webdev, design | ## Text
At the end of the previous lesson, we finally managed to place the Call to action elements perfectly in the center of our Hero Image. But the result is far from satisfactory.
First of all, you can hardly see anything here!
## Step 1 - change the color of the text
Changing the text color in Tailwind is simple and we've talked about it in the previous lesson. To change it, for example, to white, just add the .text-white class to the element.
Then all elements that are its children will take this property. So add .text-white class to the parent element of our Call to action:
By the way - we can remove .p-10 class, which was added at the beginning of the previous lesson when the Navbar was covering Call to action. We don't need it anymore.
**HTML**
```
<!-- Call to action -->
<div class="text-white">
<h1>I am learning Tailwind</h1>
<h2>And what an exciting adventure it is!</h2>
</div>
```
Slightly better, but still the contrast against the background is too weak. We'll get to that soon. Now let's try to improve the text itself a bit more.
## Step 2 - change the size of the text
By default, the typography in Tailwind has no styling, which makes headings like h1, h2. h3 etc. and paragraphs look the same.
So to make the h1 element look like the most important heading on the page, we need to use the Tailwind classes.
In Tailwind you can control the font size of any element, including headings, with the text-{size} utility. For example:
**text-xs:** Extra small text size
** text-sm:** Small text size
**text-base:** Base text size (approximately equivalent to the browser default)
**text-lg:** Large text size
**text-xl:** Extra-large text size
**text-2xl** through **text-9xl: **Incrementally larger text sizes
So let's add **.text-5xl** class to h1 element in our Call to action, and **.text-2xl** to the **h2:**
**HTML**
```
<!-- Call to action -->
<div class="text-white">
<h1 class="text-5xl">I am learning Tailwind</h1>
<h2 class="text-2xl">And what an exciting adventure it is!</h2>
</div>
```
It's taking shape, but there's still a lot of work to do.
## Step 3 - change the weight of the text
You can control the font weight of any element, including headings, with the font-{weight} utility. Have a look at a list of classes you could use:
**font-thin:** Sets the font weight to **100**
** font-extralight:** Sets the font weight to **200**
**font-light:** Sets the font weight to **300**
**font-normal:** Sets the font weight to **400**
**font-medium:** Sets the font weight to **500**
**font-semibold:** Sets the font weight to **700**
**font-extrabold:** Sets the font weight to **800**
**font-black:** Sets the font weight to **900**
So let's add **.font-semibold"** class to h1 element in our Call to action, and **.font-medium to the h2:**
**HTML**
```
<!-- Call to action -->
<div class="text-white">
<h1 class="text-5xl font-semibold">I am learning Tailwind</h1>
<h2 class="text-2xl font-medium">
And what an exciting adventure it is!
</h2>
</div>
```
Better. Now let's center it.
## Step 4 - center the text
It is true that we managed to center the Call to action in relation to the Hero Image, but still elements such as headings or the button are pressed to the left edge of the Call to Action. It would be nice if they were fully centered.
This is also very easy to do in Tailwind. Just add the text-center class to the Call to action element.
**HTML**
```
<!-- Call to action -->
<div class="text-center text-white">
<h1 class="text-5xl font-semibold">I am learning Tailwind</h1>
<h2 class="text-2xl font-medium">
And what an exciting adventure it is!
</h2>
</div>
```
Now **Call to action** looks much better, but there is still a lot of work ahead of us.

1,917,335 | Supercharging Your Cypress Tests with Custom Commands | Introduction Cypress is a powerful tool for end-to-end testing, offering a robust set of... | 0 | 2024-07-10T01:51:48 | https://dev.to/aswani25/supercharging-your-cypress-tests-with-custom-commands-4jlc | testing, webdev, javascript, cypress | ## Introduction
Cypress is a powerful tool for end-to-end testing, offering a robust set of built-in commands to interact with web applications. However, every project has unique needs that might not be fully covered by the default set of commands. This is where custom commands come in. Custom commands allow you to extend Cypress's functionality, making your tests more readable and maintainable. In this post, we’ll explore how to create and use custom commands in Cypress to enhance your test automation framework.
## Why Use Custom Commands?
Custom commands offer several benefits:
1. **Reusability:** Encapsulate common actions that are repeated across multiple tests.
2. **Maintainability:** Centralize the logic of complex actions, so changes only need to be made in one place.
3. **Readability:** Improve the readability of your tests by abstracting away implementation details.
## Setting Up Cypress
Before we dive into creating custom commands, let’s set up Cypress if you haven’t already:
```
npm install cypress --save-dev
```
After installation, open Cypress:
```
npx cypress open
```
## Creating Custom Commands
Cypress custom commands are defined in the `cypress/support/commands.js` file. Let’s walk through some examples to see how you can create and use custom commands.
**Example 1: Login Command**
Suppose you have a login form that you need to interact with frequently. You can create a custom command to handle the login process:
```js
// cypress/support/commands.js
Cypress.Commands.add('login', (email, password) => {
cy.visit('/login');
cy.get('input[name=email]').type(email);
cy.get('input[name=password]').type(password);
cy.get('button[type=submit]').click();
});
```
Now, you can use the `login` command in your tests:
```js
// cypress/integration/login.spec.js
describe('Login Tests', () => {
it('Should login with valid credentials', () => {
cy.login('test@example.com', 'password123');
cy.url().should('include', '/dashboard');
});
});
```
**Example 2: Custom Command with Assertions**
You can also add custom assertions to your commands. Let’s create a command to check if an element is visible and contains specific text:
```js
// cypress/support/commands.js
Cypress.Commands.add('shouldBeVisibleWithText', (selector, text) => {
cy.get(selector).should('be.visible').and('contain.text', text);
});
```
Usage in a test:
```js
// cypress/integration/visibility.spec.js
describe('Visibility Tests', () => {
it('Should display welcome message', () => {
cy.visit('/home');
cy.shouldBeVisibleWithText('.welcome-message', 'Welcome to the Dashboard');
});
});
```
## Best Practices for Custom Commands
1. **Name Commands Clearly:** Use descriptive names for your custom commands to make tests more understandable.
2. **Parameterize Commands:** Accept parameters to make commands flexible and reusable.
3. **Chain Commands:** Ensure commands return Cypress chainables (`cy.wrap()`) to enable chaining.
4. **Document Commands:** Add comments to describe the purpose and usage of each custom command.
## Advanced Tips
1. **TypeScript Support:** If you’re using TypeScript, you can add type definitions for your custom commands to enhance autocompletion and type checking.
2. **Error Handling:** Implement error handling within custom commands to provide informative feedback when something goes wrong.
3. **Reusable Functions:** For complex logic, create helper functions that can be used within custom commands to keep your `commands.js` file clean and focused.
## Conclusion
Custom commands in Cypress provide a powerful way to extend the framework’s capabilities, making your tests more reusable, maintainable, and readable. By encapsulating common actions and adding custom assertions, you can streamline your test automation process and focus on what matters most: ensuring your application works flawlessly.
Start implementing custom commands in your Cypress projects today and see the difference they can make in your testing workflow. Happy testing! | aswani25 |

The problem is that no one is talking about the good reason. Currently, the AI hype is all about generative text, terrible automation, and attempting to perform actions that don’t make sense.
In this blog post, engineers will learn what GenAI can actually do for them from a technical perspective.
## The Problem With LLMs
Do you like glue on your pizza? Yeah, me either.
However, LLMs think we do! Yes, this was an actual suggestion from a popular LLM-based chatbot recently. Put glue on your pizza to help the cheese not fall off.
Let’s talk about what LLMs are. Large Language Models are Data Models that have the ability to “train themselves”, and by train themselves, I mean go out on the internet and find data that already exists. Standard Data Models are trained based on Data Sets that humans create. Those Data Models are then fed to AI workloads. LLMs, instead of needing to go through that training, pull data that already exists… and we all know the quality of data on the internet.
Therein lies the problem. We still need GOOD data to feed LLMs. Otherwise, they will go scrub the trenches of Reddit for information. This leads us to the question “should gatekeepers be put in place for where LLMs can pull data from?” The answer is yes, but the next question is “Who’s responsibility is that?”.
LLMs aren’t meant to help us with the creative aspect of anything. They’re meant to remove tasks That we shouldn’t have to do manually. It’s literally just a better version of automation.
Let’s talk about a few of those tasks
## Low-Hanging Fruit
The first thing that comes to mind is highly repetitive tasks.
This brings us back to when automation first went through its popularity phase. In the world of Systems Administration, automation with PowerShell, Bash, or Python has become more and more necessary. Not because it was taking anyone’s job, but because it freed engineers up to do different tasks.
Running commands on a terminal was the far superior solution when comparing it to clicking “Next” a bunch of times on a GUI.
Now, we want to go faster. The terminal is still better for repeatability when compared to a GUI, but chatbots are superior. For example, running ‘kubectl logs’ for the millionth time isn’t necessary. Instead, engineers can use a tool like k8sgpt to pull all of the log errors and warnings for them. In this instance, k8sgpt isn’t taking jobs. It’s making the lives of engineers less trivial, just like automation did.
## Troubleshooting
From a troubleshooting perspective, GenAI makes a lot of sense. Thinking about it in the “automation 2.0” mindset, you can take what you’ve learned from troubleshooting on a terminal and make your life much easier.
Let’s take the k8sgpt example from the previous section.
In today’s world, you have two choices:
1. Run `kubectl events` and `kubectl logs` for the millionth time.
2. Have a tool that can handle it for me.
Option two sounds better.
With some GenAI magic, k8sgpt can scan your cluster to tell you if any problems are happening. You as the engineer still have to fix those problems, so the creative aspect is still in your hands. You just don’t have to do the mundane task of running the same command hundreds of times anymore.
Do the following if you want to see an example in your Kubernetes cluster.
1. Install k8sgpt
```jsx
brew tap k8sgpt-ai/k8sgpt
brew install k8sgpt
```
1. Generate an OpenAI token.
```jsx
k8sgpt generate
```
1. Add the authentication (k8sgpt uses OpenAI for authentication).
```jsx
k8sgpt auth add
```
Run the `analyze` command to see if any problems are occurring within your environment.
```jsx
k8sgpt analyze --explain
```
## Templates
Last but certainly not least, and the most important for engineers, is code templates.
Think about it - how many times have you written the same function/method/code block outline? In reality, what primarily changes is the logic within the function/method. In terms of Kubernetes Manifests, it’s the same. The values change within a Manifest, but not the template itself.
Let’s take an example from Bing Copilot.
I based it to create a Manifest template for me and it did a really good job.
What I liked the most is that not only did it create the template, but it told me what I needed to change within the code to make it unique to my particular use case.
## Closing Thoughts
Generative AI, chatbots, automation 2.0, or whatever else you’d like to call it is a good thing. It’s not a bad implementation or next step in our tech journey. Everyone has to remember that it’s not for:
1. Thinking for you.
2. Being creative.
3. Getting you off the hook to do actual work.
It’s an implementation to remove the low-hanging fruit and repetitive tasks that don’t make sense for you to do. | thenjdevopsguy |

1,917,339 | Writing cleaner code with Tailwind CSS in React | As a React developer, you might have faced challenges with managing multiple conditionals for styles... | 0 | 2024-07-09T12:59:56 | https://dev.to/heydrigh_ribeiro_1d05ea2d/writing-cleaner-code-with-tailwind-css-in-react-1icn | react, tailwindcss, vscode, beginners |
As a React developer, you might have faced challenges with managing multiple conditionals for styles in your components. Inline styles, while straightforward, can quickly become messy and hard to maintain. In this article, I'll share a solution to this problem by using a dictionary to handle styles more effectively. We'll also address a common issue with Tailwind CSS IntelliSense in VSCode and how to fix it.
## The Issue: Multiple conditionals for styles
Let's start with a common scenario. You have a Button component with different styles based on its type prop. Here's an example:
```typescript
import { ButtonProps } from './types'
const Button = ({ type = 'primary', children, ...rest }: ButtonProps) => {
return (
<button
className={
type === 'primary'
? 'bg-blue-500 text-white px-4 py-2 rounded'
: type === 'secondary'
? 'bg-gray-500 text-white px-4 py-2 rounded'
: 'border border-blue-500 text-blue-500 bg-transparent px-4 py-2 rounded'
}
{...rest}
>
{children}
</button>
)
}
export default Button
```
While this approach works, it can become unwieldy as the number of conditionals increases. It's also harder to maintain and less readable.
## The Solution: Using a dictionary for styles
A cleaner approach is to use a dictionary to manage styles. This method improves code readability and takes advantage of TypeScript's typing system. Here's how you can refactor the Button component:
```typescript
import { ButtonProps, ButtonTypes } from './types'
const Button = ({ type = 'primary', children, ...rest }: ButtonProps) => {
const typeVariantClasses: Record<ButtonTypes, string> = {
primary: 'bg-blue-500 text-white px-4 py-2 rounded',
secondary: 'bg-gray-500 text-white px-4 py-2 rounded',
outlined: 'border border-blue-500 text-blue-500 bg-transparent px-4 py-2 rounded',
}
const buttonClass = typeVariantClasses[type]
return (
<button className={buttonClass} {...rest}>
{children}
</button>
)
}
export default Button
```
By using a dictionary, you separate the styling logic from the component rendering, making your code cleaner and more maintainable.
## The New Issue: Loss of Tailwind CSS IntelliSense
One downside of this approach is the loss of Tailwind CSS IntelliSense in VSCode. When you define your classes in a dictionary, VSCode no longer recognizes them as Tailwind classes, which means you lose the helpful IntelliSense suggestions.
## The Workaround: Configuring Tailwind CSS IntelliSense
Thankfully, there's a way to bring back Tailwind CSS IntelliSense for these dynamic class names. Add the following line to your VSCode user settings:
`"tailwindCSS.classAttributes": ["class", "className", ".*Styles.*", ".*Classes.*"]
`
This configuration tells VSCode to recognize any attribute that includes Styles or Classes as a Tailwind class. Here's what it looks like in practice:
With this setting, you'll get Tailwind CSS IntelliSense suggestions for dynamically generated class names, making your development process smoother and more efficient.
## Conclusion
By refactoring your components to use a dictionary for styles, you can write cleaner and more maintainable code. And with the VSCode configuration tweak, you don't have to sacrifice the convenience of Tailwind CSS intelliSense. Give this approach a try in your next project and enjoy the benefits of cleaner code and improved developer experience.

In the last post we have talked about Document and Element interfaces of DOM. In this post we are going to discuss about some other interfaces of DOM.
So let's get started🔥
## Event Interface
The Event interface represents an event which takes place on an EventTarget. An event can be triggered by the user action e.g. clicking the mouse button or tapping keyboard, or generated by APIs to represent the progress of an asynchronous task.
Many DOM elements can be set up to accept (or "listen" for) these events, and execute code in response to process (or "handle") them. Event-handlers are usually connected (or "attached") to various HTML elements (such as `<button>, <div>, <span>` etc.) using `EventTarget.addEventListener()`.
The `addEventListener()` method attaches an event handler to the specified element.
There are various events that can be performed on an element such as -:
- click -> fired when button or any other clickable element is clicked.
- blur -> fired when an element has lost focus.
- focus -> fired when an element has gained focus.
- mouseover -> fired when mouse pointer points to that element.
- mouseout
- transistionend -> fired when a CSS transistion has finished playing.
- submit -> fired when a form is submitted.
There are more events that can be performed. But these are important ones.
**Event Methods**
- `event.preventDefault()` -> It is used to prevent the default behaviour of an event. For example when a button is clicked the page is reloaded this can be prevented using this method.
There are more interfaces but these were important ones.
We can change style of HTML element using JS DOM -:
So this is it for this blog I hope you have understood it well. Please feel free to add if I have missed something.
Don't forget to follow me.

Thousands of coloured blocks “partying” as popcorn as they transform from ideas to algorithms
Mocking Up Elementary Parsers and Interpreters in Spec to Algorithm
In Spec to Algorithm (S2A), creating easy parsers and interpreters is simple and efficient. By breaking down complicated expressions into manageable parts, S2A allows developers to generate algorithms speedily. For example, think of the instance `instance([1,1], [[is, [1+1]]])`. Here, `instance` is a function that takes inputs `[1,1]` and computes the expression `[is, [1+1]] = 2`. S2A parses this expression, identifies the operation `is` (equality check), and performs the computation.
This method can be extended to various parsing and interpretation jobs. Another instance could be `instances([[[1, 2], [[is, [1+2]]]],[[3, 4], [[is, [3+4]]]]])`, and produces `C is A+B` where `A`, `B` and `C` are variables. S2A parses the input, assigns values to `A`, `B` and `C`, and computes the sum of new inputs. Such strengths make S2A an outstanding tool for developers to mock up and test easy parsers and interpreters, streamlining the development process and improving productivity.
S2A can break complex patterns into output, making algorithms out of decision trees to do it. For example, the following query returns the object given subject, verb (determiner), and object. Here, `off` refers to not breaking items into characters, which would be helpful for recombining characters.
```
spec_to_algorithm([[[input,[['A',[s,v,o]]]],[output,[['B',[o]]]]], [[input,[['A',[s,v,d,o]]]],[output,[['B',[o]]]]]], off,_).
```
This algorithm is saved as the following code:
```
:-include('auxiliary_s2a.pl').
algorithm(In_vars,
Out_var) :-
findall(Var1,(member(Var, In_vars),
characterise1(Var, Var2),
strings_atoms_numbers(Var2, Var21),
term_to_brackets(Var21, Var1)
), In_vars1),
...
```
In the following, `T1_old`, the training input is split into two non-deterministic (nd) branches for matching.
```
...
T1_old=[[nd,[[[s,v,d,o],[output,[[o]]]],[[s,v,o],[output,[[o]]]]]]],
append(In_vars1,[[output,_]], In_vars3),
rs_and_data_to_term(T1_old, In_vars3,_,[], In_vars2,_T2_old, true),
double_to_single_brackets(In_vars2, In_vars21),
append(In_vars41,[[output, T2_old]], In_vars21),
double_to_single_brackets(In_vars41, In_vars4),
...
```
In the following line, the map is [[]] because there are no variables (from multiple specs) in the output.
```
...
member(Map2,[[]]),
double_to_single_brackets(T2_old, T2_old3),
move_vars(Map2, In_vars4, T2_old3,[], Out_var2),
findall(Out_var3,remove_nd(Out_var2, Out_var3), Out_var4),
member(Out_var5, Out_var4),
term_to_list(Out_var5, Out_var6),
[Out_var6]=Out_var.
```
The following query converts Prolog code into terms and could form and calculate `B is (1+2)+3` later. A and B are downcased in the Term Prolog form, to be converted to a and b afterwards.
```
spec_to_algorithm([[[input,[['A',["A is 1+2, B is A+3."]]]],[output,[['B',[[[+,[1,2,[lower,['A']]]],[+,[[lower,['A']],3,[lower,['B']]]]]]]]]]], off,_).
```
The following excerpts from the generated algorithm show that the single spec is pattern-matched to the output. Again, there are no output variables to map, but if there were, they (for example, [A, B]->A) would be mapped from (1,1) (item 1 of the second dimension or list level) to (1) (item 1 of the first list level).
```
T1_old=[[["A is 1+2, B is A+3."],
[output,[["[","[",+,"[",1,2,"[", lower,"[", "A","]","]","]","]","[",+,"[","[", lower,"[", "A","]","]",3,"[", lower,"[", "B","]","]","]","]","]"]]]]],
...
member(Map2,[[]]),
```

1,917,344 | Build Better With Stellar Smart Contract Challenge: A Companion Guide | Interested in our web3 challenge but not sure where to start? In this post, we'll share an overview... | 0 | 2024-07-09T13:16:16 | https://dev.to/stellar/build-better-with-stellar-smart-contract-challenge-a-companion-guide-2ing | rust, smartcontract, web3, stellarchallenge | Interested in our web3 challenge but not sure where to start? In this post, we'll share an overview of web3 and blockchain technology and set you up with all the information you need to learn about Stellar and the Soroban smart contracts platform.
## A Quick Primer on Web3
### What is web3 and blockchain?
Blockchain provides a way for people around the world to collectively maintain a database without relying on a central authority. It's a model for sharing and reconciling information, designed for our interconnected, global future. [Read Blockchain Basics](https://stellar.org/resources/quick-explainer-on-crypto-blockchain-and-stellar).
### How does crypto relate to this?
The blockchain, the core technology behind cryptocurrencies, is replicated across all computers in the network. New data is added to this chain using cryptographic methods that make it simple to detect even the smallest alteration to any previous transaction. Each time a new block of data is added, the entire network effectively verifies the integrity of all earlier data. This process is known as reaching consensus.
### Why are people skeptical of crypto/blockchain?
Critics of cryptocurrency and blockchain technology often make three main arguments:
1. Crypto and blockchain lack practical applications.
2. Traditional technologies outperform blockchain for similar functions.
3. The industry faces significant regulatory uncertainty.
By participating in the Stellar ecosystem and this hackathon, we aim to challenge at least the first two points. Our goal is to show that you can:
1. Contribute to innovative decentralized finance solutions.
2. Help provide financial access to billions of people.
While regulatory uncertainty remains a concern, it’s important to remember that most emerging technologies experience regulatory uncertainty, and we encourage developers to explore these technologies responsibly. Our hope is to bridge traditional and decentralized finance in a compliant manner.
## What are Smart Contracts?
Smart contracts are programs stored on a blockchain that run automatically when predetermined conditions are met. However, a platform that only allows developers to write code to a blockchain is not enough. To create robust, practical, and sustainable products and services, additional features are necessary to ensure safe and efficient execution. [Learn about smart contract basics](https://stellar.org/learn/smart-contract-basics).
## Why are dApps interesting?
Decentralized Applications (dApps) are programs that operate on blockchain networks, enabling direct peer-to-peer services. This eliminates the need for centralized intermediaries, effectively decentralizing various processes.
A common example of a dApp is a decentralized exchange (DEX). On a DEX, users can trade assets directly with each other using a transparent, peer-to-peer order book. This removes the need for a broker or other middleman. Decentralized apps have the potential to improve efficiency and transparency across various applications. They are particularly useful for:
- Lending and borrowing
- Exchanging value
By removing intermediaries, dApps can offer these services more directly and often at lower costs than traditional centralized systems.
## DeFi Glossary
**Decentralized Finance (DeFi):** A movement that leverages decentralized networks to transform traditional financial products into trustless and transparent protocols.
- **Wallets:** Used to store digital assets like tokens or NFTs, associated with an account. Must be funded on both testnet and mainnet.Learn more about [connecting wallets to a dApp here](https://developers.stellar.org/docs/smart-contracts/guides/freighter/integrate-freighter-react).
- **Testnet:** Sandbox blockchain environment for building and prototyping.
- **Mainnet:** Production blockchain environment for real assets/transactions.
- [**Tokens:**](https://developers.stellar.org/docs/build/smart-contracts/example-contracts/tokens) These are assets that can be created or are already on the network. They can be tied to real-world value (ex. Stablecoins are pegged to real fiat currency like the dollar), they can be representative of a real-world asset, or they can simply be made unrelated to anything in the real world (ex. memecoin)
- **Staking:** Staking is the process of putting digital assets to productive use within a blockchain network. In decentralized finance (DeFi) applications, users can 'stake' their assets, allowing them to be used by the network in various ways. This often generates rewards for the asset holder in the form of earned interest.
- [**Liquidity Pools:**](https://developers.stellar.org/docs/build/smart-contracts/example-contracts/liquidity-pool) Liquidity pools are collections of funds locked in smart contracts, enabling decentralized trading, lending, and more. Users contribute assets and receive Liquidity Provider (LP) tokens, representing their share. These pools ensure liquidity for traders, reducing slippage and improving market efficiency. Liquidity providers earn rewards through transaction fees and additional incentives from DeFi platforms.
## An Overview of Web3 Development
Web3 development introduces new paradigms for creating decentralized applications. This section covers key aspects of the Web3 development process:
- **Local Development:** Local development involves using specialized tools and frameworks that allow you to write, compile, and test smart contracts locally. Stellar's new smart contract platform, Soroban, uses Rust for writing smart contracts. For local development, you'll use the Soroban CLI, which allows you to set up a local network, compile Rust contracts, and deploy them. The Stellar SDK is still used for interacting with the Stellar network, and it's available in multiple languages including JavaScript, Python, and others. Tools like the Stellar Laboratory remain useful for testing operations, and the Stellar Core can be used for running a local network for testing purposes.
- **App Hosting:** Stellar apps usually have a traditional web front-end that can be hosted on standard [web servers like Vercel](https://developers.stellar.org/docs/learn/interactive/dapps/challenges/challenge-0-crowdfund#checkpoint-4--ship-it-). The backend interacts with the Stellar network through Horizon API. Smart contracts on Stellar, called Stellar Core Contracts, are deployed directly to the Stellar network. Users interact with your app through Stellar-compatible wallets or interfaces you create using the Stellar SDK.
- **Compute and Storage:** Computation happens on the Stellar network when transactions or operations are processed. For data storage, Stellar offers limited on-chain storage through account data entries. For larger data needs, developers often use off-chain solutions and store references or hashes on the Stellar blockchain. Payments for network usage are made in Lumens (XLM), Stellar's native currency.
For more in-depth information about the Stellar tech stack, visit [our dev docs](https://developers.stellar.org/docs/learn/fundamentals).

1,917,345 | Best Practices for Custom Commands in Cypress: A Detailed Guide | Introduction In our previous post, we introduced the concept of custom commands in Cypress... | 0 | 2024-07-11T12:31:33 | https://dev.to/aswani25/best-practices-for-custom-commands-in-cypress-a-detailed-guide-cl2 | testing, webdev, javascript, cypress | ## Introduction
In our previous post, we introduced the concept of custom commands in Cypress and demonstrated how they can simplify and enhance your testing framework. This follow-up post dives deeper into the best practices for creating and using custom commands, providing detailed examples to ensure your tests are maintainable, readable, and robust.
## Why Best Practices Matter
Following best practices when creating custom commands ensures that your tests remain scalable, easy to understand, and quick to update. Properly structured custom commands can significantly reduce code duplication and improve the overall quality of your test suite.
## Best Practices for Custom Commands
**1. Name Commands Clearly**
Clear and descriptive names make your commands easy to understand and use. A good command name should convey its purpose without needing additional context.
**Example:**
```js
// cypress/support/commands.js
Cypress.Commands.add('login', (email, password) => {
cy.visit('/login');
cy.get('input[name=email]').type(email);
cy.get('input[name=password]').type(password);
cy.get('button[type=submit]').click();
});
```
**Usage:**
```js
// cypress/integration/login.spec.js
describe('Login Tests', () => {
it('Should login with valid credentials', () => {
cy.login('test@example.com', 'password123');
cy.url().should('include', '/dashboard');
});
});
```
**2. Parameterize Commands**
Commands should accept parameters to enhance their flexibility and reusability. This allows the same command to be used in different contexts with different data.
**Example:**
```js
// cypress/support/commands.js
Cypress.Commands.add('fillForm', (formData) => {
cy.get('input[name=firstName]').type(formData.firstName);
cy.get('input[name=lastName]').type(formData.lastName);
cy.get('input[name=email]').type(formData.email);
cy.get('button[type=submit]').click();
});
```
**Usage:**
```js
// cypress/integration/form.spec.js
describe('Form Tests', () => {
it('Should submit the form with valid data', () => {
const formData = {
firstName: 'John',
lastName: 'Doe',
email: 'john.doe@example.com'
};
cy.fillForm(formData);
cy.get('.success-message').should('be.visible');
});
});
```
**3. Chain Commands**
Ensure custom commands return Cypress chainables using `cy.wrap()` to enable chaining and maintain the flow of Cypress commands.
**Example:**
```js
// cypress/support/commands.js
Cypress.Commands.add('selectDropdown', (selector, value) => {
cy.get(selector).select(value).should('have.value', value);
return cy.wrap(value);
});
```
**Usage:**
```js
// cypress/integration/dropdown.spec.js
describe('Dropdown Tests', () => {
it('Should select a value from the dropdown', () => {
cy.visit('/dropdown-page');
cy.selectDropdown('#dropdown', 'Option 1').then((value) => {
expect(value).to.equal('Option 1');
});
});
});
```
**4. Document Commands**
Add comments to your custom commands to describe their purpose and usage. This helps other developers understand your code and use it correctly.
**Example:**
```js
// cypress/support/commands.js
/**
* Custom command to login to the application
* @param {string} email - User email
* @param {string} password - User password
*/
Cypress.Commands.add('login', (email, password) => {
cy.visit('/login');
cy.get('input[name=email]').type(email);
cy.get('input[name=password]').type(password);
cy.get('button[type=submit]').click();
});
```
**5. Modularize Common Actions**
Encapsulate common actions within custom commands to promote reuse and reduce duplication. This also makes tests more readable by abstracting complex interactions.
**Example:**
```js
// cypress/support/commands.js
Cypress.Commands.add('addItemToCart', (itemName) => {
cy.get('.product-list').contains(itemName).click();
cy.get('.add-to-cart').click();
});
```
Usage:
```js
// cypress/integration/cart.spec.js
describe('Cart Tests', () => {
it('Should add an item to the cart', () => {
cy.visit('/shop');
cy.addItemToCart('Laptop');
cy.get('.cart-items').should('contain', 'Laptop');
});
});
```
## Conclusion
By following these best practices, you can create custom commands in Cypress that are not only powerful but also maintainable and easy to understand. Clear naming, parameterization, chaining, documentation, and modularization are key to writing effective custom commands. Implement these practices in your test automation framework to enhance the quality and efficiency of your tests.
Start refining your custom commands today, and take your Cypress tests to the next level. Happy testing! | aswani25 |

1,917,347 | Microsoft 365 Groups: A Comprehensive Guide | Microsoft 365 Groups is a powerful feature within the Microsoft 365 suite that enhances collaboration... | 0 | 2024-07-09T13:18:17 | https://dev.to/borisgigovic/microsoft-365-groups-a-comprehensive-guide-38ld | microsoft365, microsoftsecuritygroups, cloudsecurity, identityandaccess | Microsoft 365 Groups is a powerful feature within the Microsoft 365 suite that enhances collaboration and communication among team members. This comprehensive guide aims to demystify Microsoft 365 Groups by explaining what they are, how they can be used, the differences between Microsoft 365 Groups and legacy distribution and security groups, and integration scenarios with various Microsoft 365 services.
## What Are Microsoft 365 Groups?
Microsoft 365 Groups is a service that enables users to create and manage groups for collaboration and communication. A group is essentially a collection of people, resources, and tools brought together to facilitate teamwork and streamline project management. When you create a Microsoft 365 Group, you automatically get access to several collaboration tools, such as a shared mailbox, calendar, document library, OneNote notebook, and more.
## Key Features of Microsoft 365 Groups
1. Shared Mailbox: Each group gets a shared mailbox that members can use to communicate with each other and external parties.
2. Shared Calendar: A shared calendar allows group members to schedule and manage events and meetings.
3. Document Library: Each group gets a document library in SharePoint for storing and collaborating on files.
4. OneNote Notebook: A shared OneNote notebook is provided for taking notes and organizing information.
5. Planner: Microsoft Planner is integrated with groups to help with task management and project planning.
6. Microsoft Teams: Groups can be integrated with Microsoft Teams for real-time communication and collaboration.
## How Microsoft 365 Groups Can Be Used
## Collaboration and Communication
Microsoft 365 Groups enhance collaboration by providing a centralized space where team members can communicate, share documents, and manage tasks. This is particularly useful for project-based teams that need to coordinate efforts and stay aligned.
**Example**
A marketing team can create a Microsoft 365 Group to manage their campaigns. They can use the shared mailbox for email communication, the document library for storing marketing materials, and Planner to track campaign tasks.
## Project Management
Groups can be used for project management by leveraging tools like Planner and the shared calendar. This helps teams stay organized and ensures that everyone is aware of deadlines and responsibilities.
**Example**
A software development team can create a group for each project. They can use the shared calendar to schedule milestones, Planner to assign tasks, and the document library to store project documentation.
## External Collaboration
Microsoft 365 Groups can include external users, making it easy to collaborate with partners, vendors, and clients. External members can be granted access to specific group resources while maintaining security and compliance.
**Example**
A consulting firm can create a group for each client engagement. External clients can be added to the group to facilitate communication and document sharing.
## Departmental Coordination
Departments within an organization can use Microsoft 365 Groups to streamline internal communication and resource sharing. This reduces the reliance on email and improves transparency.
**Example**
The HR department can create a group to manage internal communications, store policy documents, and schedule departmental meetings.
## Differences Between Microsoft 365 Groups and Legacy Distribution and Security Groups
## Distribution Groups
Distribution groups are used for sending email notifications to a group of people. They do not have associated collaboration tools like shared mailboxes or document libraries.
## Key Differences
- **Purpose**: Distribution groups are primarily for email distribution, while Microsoft 365 Groups offer a broader range of collaboration tools.
- **Resources**: Microsoft 365 Groups provide access to shared mailboxes, calendars, document libraries, and more, whereas distribution groups do not.
- **Management**: Microsoft 365 Groups are managed through the Microsoft 365 Admin Center, while distribution groups are typically managed through Exchange.
## Security Groups
Security groups are used to manage user permissions and access to resources. They do not provide collaboration tools and are focused on security and access control.
## Key Differences
- **Purpose**: Security groups are used for access management, while Microsoft 365 Groups focus on collaboration and communication.
- **Resources**: Microsoft 365 Groups come with shared resources like mailboxes and document libraries, while security groups do not.
- **Management**: Security groups are managed through Active Directory, whereas Microsoft 365 Groups are managed through the Microsoft 365 Admin Center.
## Integration Scenarios with Microsoft 365 Services
## Microsoft Teams
Microsoft 365 Groups can be integrated with Microsoft Teams to provide a seamless collaboration experience. When a group is created in Microsoft Teams, it automatically creates a Microsoft 365 Group with all its associated resources.
**Example**
A sales team can use Microsoft Teams for real-time communication and collaboration while leveraging the shared mailbox, calendar, and document library provided by the Microsoft 365 Group.
## SharePoint
Groups are closely integrated with SharePoint, providing each group with a dedicated site for document management and collaboration. This integration ensures that documents are easily accessible and can be collaboratively edited.
**Example**
A research team can use the SharePoint site associated with their Microsoft 365 Group to store and collaborate on research papers and data.
## Planner
Microsoft Planner is integrated with Microsoft 365 Groups, allowing teams to create, assign, and track tasks. This helps in efficient project management and ensures that tasks are completed on time.
**Example**
A product development team can use Planner to manage the development process, assign tasks to team members, and track progress.
## Outlook
Groups are integrated with Outlook, providing a shared mailbox and calendar. This integration allows team members to stay updated with group communications and schedule events easily.
**Example**
A finance team can use the shared mailbox in Outlook to manage departmental communications and the shared calendar to schedule financial reviews and meetings.
## OneNote
Each Microsoft 365 Group comes with a shared OneNote notebook, facilitating note-taking and information organization. This is useful for keeping meeting notes, project documentation, and brainstorming ideas in one place.
**Example**
A project management office can use the shared OneNote notebook to document project plans, meeting notes, and lessons learned.
## Power Automate
Microsoft 365 Groups can be integrated with Power Automate to automate repetitive tasks and workflows. This enhances productivity and ensures consistency in processes.
**Example**
An IT support team can create a workflow that automatically adds new support tickets to a Planner board and notifies team members via the shared mailbox.
## Ensuring Full Functionality
## Proper Group Management
Regularly review and manage group memberships to ensure that only relevant users have access to group resources. Use dynamic membership rules to automate group management based on user attributes.
## Security and Compliance
Implement security and compliance policies to protect group data. Use sensitivity labels, retention policies, and access controls to secure group resources.
## Training and Adoption
Provide training to users on how to effectively use Microsoft 365 Groups and their associated tools. Encourage adoption by demonstrating the benefits of using groups for collaboration and project management.
## Monitoring and Reporting
Use the Microsoft 365 Admin Center to monitor group usage and activity. Generate reports to track group performance and identify areas for improvement.
## Conclusion
Microsoft 365 Groups is a versatile and powerful feature that enhances collaboration and communication within an organization. By understanding the various types of groups, their uses, and integration scenarios, you can leverage Microsoft 365 Groups to streamline your workflows and improve team productivity.

1,917,359 | Flux Fundamentals: Mastering GitOps Deployments with Flux | GitOps, a set of principles that utilize Git as the single source of truth for managing... | 0 | 2024-07-09T13:32:43 | https://dev.to/platform_engineers/flux-fundamentals-mastering-gitops-deployments-with-flux-3k9o | GitOps, a set of principles that utilize Git as the single source of truth for managing infrastructure, has revolutionized the way platform engineering teams manage and deploy applications. One of the key tools in this space is Flux, an open-source project that automates the deployment of applications to Kubernetes clusters. In this blog, we will delve into the fundamentals of Flux and explore how it can be used to master GitOps deployments.
### Understanding Flux
Flux is a GitOps operator that automates the deployment of applications to Kubernetes clusters. It does this by continuously reconciling the cluster state with the desired state declared in a Git repository. This means that any changes made to the Git repository are automatically applied to the cluster, ensuring that the cluster remains in the desired state.
### Key Features of Flux
Flux provides several key features that make it an ideal choice for GitOps deployments:
- **Multi-tenancy**: Flux supports multi-tenancy, allowing each source repository to have its own set of permissions.
- **Health Checks and Alerts**: Flux provides operational insights through health checks, events, and alerts, ensuring that any issues with the cluster are quickly identified and addressed.
- **Support for Multiple Source Repositories**: Flux can synchronize with multiple source repositories, making it easy to manage multiple applications and environments.
- **Support for Various File Types**: Flux supports YAML-formatted manifests, Helm charts, and Kustomize files, making it versatile and adaptable to different deployment scenarios.
### Bootstrapping Flux
To get started with Flux, you need to bootstrap it onto your Kubernetes cluster. This involves creating a Git repository, adding Flux component manifests to the repository, deploying Flux components to the cluster, and configuring Flux to track the desired path in the repository.
Here is an example of how to bootstrap Flux using the Flux CLI:
```bash
flux bootstrap github \
--owner=$GITHUB_USER \
--repository=fleet-infra \
--branch=main \
--path=./clusters/my-cluster \
--personal
```
### Deploying Applications with Flux
Once Flux is bootstrapped, you can deploy applications to your Kubernetes cluster using GitOps. This involves creating a GitRepository manifest pointing to the application repository, committing and pushing the manifest to the repository, and then applying the manifest to the cluster.
Here is an example of how to create a GitRepository manifest and deploy an application using Flux:
```yaml
apiVersion: source.toolkit.fluxcd.io/v1
kind: GitRepository
metadata:
name: podinfo
namespace: flux-system
spec:
interval: 1m
ref:
branch: master
url: https://github.com/stefanprodan/podinfo
```
### Customizing Application Configuration
Flux also supports customizing application configuration through Kustomize patches. This allows you to make environment-specific changes to your application without modifying the original code.
Here is an example of how to create a Kustomize patch and apply it to an application:
```yaml
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
metadata:
name: podinfo
namespace: flux-system
spec:
interval: 1m
ref:
branch: master
url: https://github.com/stefanprodan/podinfo
patches:
- path: ./kustomize/patch.yaml
```
### Conclusion
In conclusion, Flux is a powerful tool for mastering GitOps deployments. Its ability to automate the deployment of applications to Kubernetes clusters, support for multiple source repositories, and customization options through Kustomize patches make it an ideal choice for [platform engineering](www.platformengineers.io) teams. By following the steps outlined in this blog, you can get started with Flux and begin deploying applications using GitOps principles. | shahangita | |

1,917,362 | Why does Woovi use MongoDB? | This article explains our decision-making at Woovi to build our fintech on top of MongoDB. ... | 0 | 2024-07-09T18:15:28 | https://dev.to/woovi/why-does-woovi-use-mongodb-m04 | mongodb, woovi | This article explains our decision-making at Woovi to build our fintech on top of MongoDB.
## Why MongoDB?
I think the best two general databases that you can choose to build your Startup are MongoDB or PostgreSQL.
We decided to go with MongoDB for several reasons, outlined below.
## Database migrations
When you are building a new product your data modeling and schema will evolve, and you need to perform database migrations to ensure your codebase only handles one version of these schemas.
When working with SQL you need to perform two types of migrations: structure and data migrations.
Structure migrations are the ones that add, modify, or remove your database schema. Usually using SQL DDL.
Data migration is when you migrate from one data format to another data format. It is like running a _.map_ in some items of some collections. Usually, a script uses database cursors.
When using MongoDB we don't need to care about structure migrations, only with data migrations. No need for up-and-down migrations. You just move forward.
## No need for ORM
Most projects using SQL use an ORM instead of writing pure SQL.
ORM is a bad abstraction that will generate non-optimized queries.
The DX of writing pure SQL is not the best one in most programming languages.
With MongoDB you just use `mongoose` to define your schema and use find, save, and aggregate to perform queries and migrations.
## Database modeling
When you are doing database modeling in MongoDB you focus more on the workload that your product will perform, you focus more on how you are going to read the data than on creating a lot of tables and relationships.
When using MongoDB you can achieve the same data modeling with fewer tables/collections than the counter-party using SQL.
You ended up with a simpler model.
When working on an early stage stage you need to iterate a lot your data model until you finds the one that works, MongoDB makes it easy to iterate.
Another benefit is that you focus on more decoupled modeling with fewer joins/lookups. This helps you at scale if you want to break your system into some microservices.
A decoupled data model creates a decoupled codebase.
## Database scaling
MongoDB is easier to scale than PostgreSQL. It is easier to set up a replica set or sharding than when using PG.
Database scaling is hard for both.
You can also have a hidden replica to use in your BI system like metabase
## Indexes
MongoDB has many types of indexes to support many use cases.
- single field index: when filtering by a single field)
- compound field index: when filtering by many fields at the same time [https://emptysqua.re/blog/optimizing-mongodb-compound-indexes/](https://emptysqua.re/blog/optimizing-mongodb-compound-indexes/)
- multikey index: array fields
text index: full-text search in many fields in the same collection
- wildcard index: to handle metadata, schemaless design, filter for fields that you don't know yet
- geospatial index: to filter by location, near, intersection, and more
- ttl index
## Unstructured data
NoSQL thrives to store unstructured data that can be processed later on.
## Change Streams
MongoDB Change Streams enable change data capture that makes it possible to sync MongoDB data into other systems, like updating materialized views, updating elastic search data, and enabling realtime updates to WebSockets.
## In Conclusion
MongoDB is a great database for your Startup, and it will handle the scaling when needed.
As your product grows you need to add other specific databases to handle different use cases. Like Redis, Elastic Search, and others.

1,917,364 | Create Architecture Diagram as Code for a 2-Tier Bookstore Application | How to Create Architecture Diagram as Code for a 2-Tier Bookstore Application Creating... | 7,690 | 2024-07-09T15:20:30 | https://dev.to/aws-builders/create-architecture-diagram-as-code-for-a-2-tier-bookstore-application-2356 | aws, python, architecture, devrel | ## **How to Create Architecture Diagram as Code for a 2-Tier Bookstore Application**
Creating architecture `diagrams as code` is a modern approach that offers numerous benefits over traditional diagramming methods, including architecture diagram automation, and consistency. This approach allows for version-controlled, easily reproducible, and modifiable diagrams that can evolve alongside your application.
This article will guide you through the process of creating an architecture diagram for a 2-tier bookstore application in AWS Cloud using `Python` and its [`diagrams`] library.
## Why Diagrams as Code?
Diagrams as code offer several advantages over traditional diagramming tools:
- **Version Control**: Changes to diagrams can be tracked over time.
- **Automation**: Diagrams can be automatically updated as part of your CI/CD pipeline.
- **Consistency**: Ensures uniformity in the presentation of your architecture.
Diagram as code makes it easy to **Architects** and **Developers** to update their architecture diagram, and use version control to maintain various versions of the Architecture.
## Tools & Technology Used
We'll use the [`diagrams`] Python library, which allows for creating cloud system architecture diagrams using code. It supports various providers, including **AWS, GCP, Azure**, and many more.
## Prerequisites
- Python 3.x installed on your system
- Basic understanding of Python programming
- Familiarity with virtual environments in Python
## Sample Application: Bookstore 2-Tier Architecture
Our sample application is a simple bookstore with a 2-tier architecture consisting of a frontend and a backend, along with a database. It also includes a CI/CD pipeline and monitoring services.
To run the Python code that generates an architecture diagram for a bookstore application, follow these detailed steps. These steps include setting up a virtual environment, installing dependencies, and running the script.
### Step 1: Setting Up a Python Virtual Environment
First, you need to create a virtual environment. A virtual environment is a self-contained directory that contains a Python installation for a particular version of Python, plus a number of additional packages.
1. Open your terminal.
2. Navigate to the directory where you want to store your project.
3. Run the following command to create a virtual environment named `venv`:
```bash
python3 -m venv venv
```
### Activate the Virtual Environment
Activate the virtual environment to use it for your project.
- On macOS and Linux:
```bash
source venv/bin/activate
```
- On Windows:
```bash
.\venv\Scripts\activate
```
### Install the Required Libraries
With the environment activated, install the `diagrams` library, which enables you to generate architecture diagrams using Python code.
```bash
pip install diagrams graphviz
```
## Step 2: Writing the Diagram Code
Create a new Python file named [`architecture.py`] and open it in your favorite text editor.
Copy the following code into the file. This code defines the architecture of a simple bookstore application with a 2-tier architecture, including a frontend, a backend, a database, a CI/CD pipeline, and monitoring services.
```python
from diagrams import Diagram, Cluster, Edge
from diagrams.aws.compute import EC2
from diagrams.aws.database import RDS
from diagrams.aws.network import ELB, Route53
from diagrams.aws.general import Client
from diagrams.onprem.network import Internet
from diagrams.onprem.monitoring import Prometheus, Grafana
from diagrams.programming.framework import React
from diagrams.custom import Custom
graph_attr = {'ranksep': '1.0'} #, 'rankdir': 'TB'}
with Diagram("Two Tier Application Architecture", show=False, graph_attr=graph_attr):
with Cluster("User Network"):
client = Client("User")
internet = Internet("Internet")
with Cluster("CI/CD Pipeline"):
with Cluster("Source Code"):
react = React("React")
terraform = Custom("Terraform", "./tf.png")
github_actions = Custom("GitHub Actions", "./ghactions.png")
with Cluster("AWS Cloud"):
with Cluster("VPC"):
with Cluster("Public Subnet"):
dns = Route53("DNS")
lb = ELB("Load Balancer")
# public_subnet = Subnet("Public Subnet")
dns >> lb
with Cluster("Private Subnet for Backend"):
# private_subnet_backend = Subnet("Private Subnet")
backend = EC2("Backend (Node.js)")
db = RDS("Database (MongoDB)")
backend >> db
with Cluster("Private Subnet for Frontend"):
# private_subnet_frontend = Subnet("Private Subnet")
frontend = EC2("Frontend (React)")
# private_subnet_frontend >> frontend
with Cluster("Monitoring"):
prometheus = Prometheus("Prometheus")
grafana = Grafana("Grafana")
client >> internet >> dns
react >> github_actions
terraform >> github_actions
lb >> Edge(label="HTTP/HTTPS") >> frontend
lb >> Edge(label="HTTP/HTTPS") >> backend
backend >> Edge(label="Database Connection") >> db
backend >> prometheus
frontend >> prometheus
db >> prometheus
prometheus >> grafana
# Connecting CI/CD Pipeline to AWS Cloud
github_actions >> Edge(color="blue", style="dashed", label="Deploy to AWS Cloud") >> dns
# Creating Custom Node
# Custom Node: We can create a custom node to represent the subnet.
# The diagrams library allows you to create custom nodes with your own images,
# which can be useful for representing components that are not available as predefined classes.
# from diagrams import Node
# class Subnet(Node):
# _icon_dir = "path/to/custom/icons"
# _icon = "subnet.png"
```
Full source code has been available in GitHub. Please [check it out here](https://github.com/chefgs/gpt_demos/tree/main/bookstore-app/arch-diagram).
## Python Code Break down of the Architecture Diagram
Let's break down the Python code used to generate the architecture diagram step-by-step:
```python
from diagrams import Diagram, Cluster, Edge
from diagrams.aws.compute import EC2
from diagrams.aws.database import RDS
from diagrams.aws.network import ELB, Route53
from diagrams.aws.devtools import Codepipeline, Codebuild
from diagrams.aws.general import Client
from diagrams.onprem.network import Internet
from diagrams.onprem.container import Docker
from diagrams.onprem.monitoring import Prometheus, Grafana
from diagrams.programming.language import Python
```
### Imports
- **Diagram, Cluster, Edge**: Core components from the `diagrams` library to create diagrams, group components, and define connections.
- **AWS Components**: Various AWS components (`EC2`, `RDS`, `ELB`, `Route53`, `Codepipeline`, `Codebuild`, `Client`) to represent different parts of the architecture.
- **On-Prem Components**: Components for non-cloud (on-prem) services (`Internet`, `Docker`, `Prometheus`, `Grafana`).
- **Programming Language**: Represents GitHub Actions with a generic programming language icon (`Python`).
### Creating the Diagram
```python
with Diagram("Two Tier Application Architecture", show=False, graph_attr=graph_attr):
with Cluster("User Network"):
client = Client("User")
internet = Internet("Internet")
```
- **Diagram**: The main context for the diagram, with the title "Bookstore Application Architecture". `show=False` prevents the diagram from being immediately displayed.
- **Client**: Represents the user accessing the application.
- **DNS**: Uses Route53 to represent the DNS service.
### CI/CD Pipeline
```python
with Cluster("CI/CD Pipeline"):
with Cluster("Source Code"):
react = React("React")
terraform = Custom("Terraform", "./tf.png")
github_actions = Custom("GitHub Actions", "./ghactions.png")
```
- **Cluster**: Groups components logically. Here, it groups the CI/CD pipeline components.
- **GitHub Actions**: Represented using a generic programming language user uploaded icon (`ghactions.png`).
- **React and Custom**: MERN code and Terraform code representation (with user uploaded Terraform icon). They are integrated with the GitHub action workflow for CICD deployment.
### AWS Cloud & Monitoring Components
```python
with Cluster("AWS Cloud"):
with Cluster("VPC"):
with Cluster("Public Subnet"):
dns = Route53("DNS")
lb = ELB("Load Balancer")
# public_subnet = Subnet("Public Subnet")
dns >> lb
with Cluster("Private Subnet for Backend"):
# private_subnet_backend = Subnet("Private Subnet")
backend = EC2("Backend (Node.js)")
db = RDS("Database (MongoDB)")
backend >> db
with Cluster("Private Subnet for Frontend"):
# private_subnet_frontend = Subnet("Private Subnet")
frontend = EC2("Frontend (React)")
# private_subnet_frontend >> frontend
with Cluster("Monitoring"):
prometheus = Prometheus("Prometheus")
grafana = Grafana("Grafana")
```
- **AWS Cloud Cluster**: Groups all AWS cloud components.
- **Load Balancer (ELB) and DNS**: Distributes traffic between frontend and backend services. DNS used to be exposed to the public internet.
- **VPC Cluster**: VPC cluster has been created to indicate private and public subnet networks for UI layer and backend layer.
- **Backend Service Cluster**: Contains the backend server (Node.js on EC2) and the database (MongoDB on RDS).
- **Frontend Service Cluster**: Contains the frontend server (React on EC2).
- **Monitoring Cluster**: Contains Prometheus for metrics collection and Grafana for visualization.
### Defining Connections
```python
client >> internet >> dns
react >> github_actions
terraform >> github_actions
lb >> Edge(label="HTTP/HTTPS") >> frontend
lb >> Edge(label="HTTP/HTTPS") >> backend
backend >> Edge(label="Database Connection") >> db
backend >> prometheus
frontend >> prometheus
db >> prometheus
prometheus >> grafana
```
- **Connections**: Represented using `>>` operator, defining the flow and connections between components.
- **client >> internet >> dns**: The user accesses the DNS service, via public internet.
- **react >> github_actions**: Represents the CI/CD pipeline flow from MERN Code into integration GitHub Actions.
- **terraform >> github_actions**: Represents the CI/CD pipeline flow from Terraform infra deployment code into integration GitHub Actions.
- **lb >> Edge(label="HTTP/HTTPS") >> frontend**: The load balancer directs traffic to the frontend services.

### Summary of Diagram Breakdown
The Python script leverages the `diagrams` library to create a structured, version-controlled architecture diagram. It groups related components into clusters, defines the interactions between them using directed edges, and ensures the entire infrastructure is visually represented in a clear, consistent manner. This approach makes it easy to update and maintain the architecture diagram as the application evolves.
### Adding custom node for user-defined components
Let us see how to create a custom node in Python using the `diagrams` library. This library allows developers to visually represent their infrastructure and systems.
The purpose of creating a custom node is to represent a user-defined architecture component and ICON/logo.
Method 1: Defining the `from diagrams.custom import Custom` Diagrams Custom module, and using this section along with the valid logo/ICON PNG image of the architecture component.
For example, we have added Terraform Icon using this method.
We need to store the license free PNG image for this purpose.
```
from diagrams.custom import Custom
terraform = Custom("Terraform", "./tf.png")
```
Method 2:
As depicted on the _commented out_ example, a custom node definition for subnet has been added.
A subnet is part of VPC architecture &, and is a logical subdivision of an IP network. The ability to create custom nodes is particularly useful when the predefined classes provided by the `diagrams` library do not cover all the components you need to represent in your architecture diagrams.
- The code snippet begins by importing the `Node` class from the `diagrams` library.
- This `Node` class is the base class for all diagram nodes, and custom nodes can be created by subclassing it.
- The subclass shown in the example is named `Subnet`, indicating its intended use to represent subnetworks.
Within the `Subnet` class, two class attributes are defined:
- `_icon_dir`: This attribute specifies the directory path where custom icons are stored. In this example, it's set to `"path/to/custom/icons"`, which should be replaced with the actual path to the directory containing the icon files.
- `_icon`: This attribute specifies the filename of the icon image that will be used to visually represent the node in the diagram. Here, it is set to `"subnet.png"`, indicating that an image file named `subnet.png` in the specified directory will be used as the icon for the subnet node.
By defining these attributes, the `Subnet` class tells the `diagrams` library where to find the custom icon and which icon to use when rendering the subnet node in a diagram. This allows for a more customized and visually accurate representation of the system's architecture.
## Step 3: Generating the Diagram
Ensure the Python script ([`architecture.py`] is saved in your project directory.
Run the script to generate the architecture diagram. Ensure your virtual environment is activated, then execute:
```bash
python architecture.py
```
This command executes the script, which generates a PNG image named `Bookstore Application Architecture.png` in the same directory, illustrating the architecture of the bookstore application.
### Understanding the Diagram `Bookstore Application Architecture.png`
- **User Network**: Represents the entry point for users, connecting through the internet to our application.
- **CI/CD Pipeline**: Showcases the automation for deploying our React frontend and Terraform configurations.
- **AWS Cloud**: Hosts our application, including the load balancer, DNS service, backend service (Node.js), frontend service (React), and database (MongoDB).
- **Monitoring**: Utilizes Prometheus for monitoring and Grafana for visualization.
## Step 4: Deactivating the Virtual Environment
Once you're done working in the virtual environment, you can deactivate it by running:
```bash
deactivate
```
This command returns you to the system’s default Python interpreter with all its installed libraries.
By following these steps, you've successfully set up a virtual environment, installed necessary dependencies, and run a Python script to generate an architecture diagram for a bookstore application.
## Benefits & Use-cases of Diagram as code
Diagrams as code offer numerous benefits in real-time project scenarios, providing a powerful and efficient way to manage and visualize complex system architectures. Here are some typical use-cases:
1. Documentation and Communication
Architecture Documentation: Automatically generate up-to-date diagrams that accurately reflect the current state of the system architecture. This ensures that documentation is always current and avoids the pitfalls of manually maintained diagrams.
Team Communication: Facilitate better communication among team members by providing a clear and consistent visualization of the architecture, which can be easily shared and discussed.
2. Infrastructure as Code (IaC) Integration
IaC Synchronization: Use diagrams as code to keep architecture diagrams in sync with the actual infrastructure managed by tools like Terraform, CloudFormation, or Ansible. This provides a visual representation of the infrastructure that matches the code.
Automated Updates: Automatically update architecture diagrams as part of the CI/CD pipeline whenever changes are made to the IaC scripts. This ensures that diagrams reflect the latest infrastructure changes.
3. CI/CD Pipeline Integration
Pipeline Visualization: Visualize the CI/CD pipeline stages and the flow of code from development to production. This helps in understanding the deployment process and identifying potential bottlenecks.
Deployment Architecture: Generate diagrams that show the architecture of the deployed application, including microservices, databases, and other components. This can be especially useful for troubleshooting and optimizing deployment strategies.
4. Microservices and Distributed Systems
Service Dependencies: Visualize the dependencies and interactions between microservices in a distributed system. This helps in understanding the overall system behavior and identifying potential points of failure.
Dynamic Environments: Automatically generate diagrams for dynamic environments where services and dependencies may frequently change. This ensures that the architecture diagram remains accurate and up-to-date.
5. Architecture diagram AI automation:
If you want to create AI to generate architecture diagram for given prompt, then we can use this method of generating diagrams
## Conclusion
You've now successfully created an architecture diagram as code for a 2-tier bookstore application. This method allows for easy updates, version control, and integration into CI/CD pipelines, making it an efficient tool for modern software development practices.

1,917,365 | WebAssembly: Revolutionizing Web Performance | The web has come a long way since the days of static HTML pages. Modern web applications are rich,... | 0 | 2024-07-09T13:42:44 | https://dev.to/andylarkin677/webassembly-revolutionizing-web-performance-1jla | webdev, javascript, webassembly, typescript | The web has come a long way since the days of static HTML pages. Modern web applications are rich, interactive, and complex, often rivaling native applications in functionality and user experience. However, achieving high performance with JavaScript, the primary language of the web, can be challenging, especially for computation-intensive tasks. Enter WebAssembly (Wasm), a game-changer in the web development landscape. WebAssembly promises to revolutionize web performance, making it possible to run high-speed, low-level code in the browser. Let's explore what WebAssembly is, how it works, and why it's transforming the web.
What is WebAssembly?
WebAssembly is a binary instruction format designed as a portable target for the compilation of high-level languages like C, C++, and Rust. Unlike JavaScript, which is an interpreted language, WebAssembly code is compiled to a binary format that is executed at near-native speed by the web browser. It is supported by all major browsers, including Chrome, Firefox, Safari, and Edge.
How Does WebAssembly Work?
WebAssembly works by compiling high-level source code into a binary format that can be executed by the browser's virtual machine. Here's a simplified breakdown of the process:
Compilation: Source code written in a high-level language (e.g., C, C++) is compiled into WebAssembly bytecode using a compiler like Emscripten or Rust's built-in toolchain.
Loading and Execution: The WebAssembly module is loaded into the web page and executed by the browser. WebAssembly modules are typically loaded alongside JavaScript, which can interact with and control the WebAssembly code.
Benefits of WebAssembly
1. Performance
The most significant advantage of WebAssembly is its performance. Because it is a low-level bytecode, it can run at near-native speed. This makes it ideal for performance-critical applications like games, video editing, and CAD tools, which were previously impractical to run in the browser.
2. Portability
WebAssembly is designed to be portable and can run on any platform that supports the web. This means developers can write code once and run it anywhere, reducing the need for platform-specific codebases.
3. Interoperability
WebAssembly is designed to work seamlessly with JavaScript. Developers can call WebAssembly functions from JavaScript and vice versa, making it easy to integrate into existing web applications.
4. Security
WebAssembly modules run in a sandboxed environment, providing a layer of security. This isolation helps prevent malicious code from affecting the host system, making it a safe choice for running untrusted code.
Use Cases of WebAssembly
1. Gaming
WebAssembly's performance capabilities make it an excellent choice for web-based games. Games that require intensive graphics and fast computations can benefit significantly from WebAssembly.
2. Web Applications
Applications that demand high performance, such as video editors, image processing tools, and scientific simulations, can achieve better performance with WebAssembly.
3. Cross-Platform Libraries
Developers can compile existing libraries written in languages like C and C++ to WebAssembly, enabling them to be used in web applications. This reuse of existing code can save significant development time and effort.
Challenges and Limitations
While WebAssembly offers numerous benefits, it is not without its challenges:
Debugging: Debugging WebAssembly code can be more challenging compared to JavaScript, as it involves working with lower-level code.
Complexity: Integrating WebAssembly into existing JavaScript projects can add complexity, especially for developers unfamiliar with low-level programming.
Tooling and Ecosystem: Although growing, the tooling and ecosystem around WebAssembly are not as mature as those for JavaScript.
Conclusion
WebAssembly is a powerful technology that is revolutionizing web performance. By enabling near-native speed for web applications, it opens up new possibilities for what can be achieved in the browser. While there are challenges to adopting WebAssembly, its benefits make it a compelling option for developers looking to build high-performance web applications. As the ecosystem continues to mature, we can expect to see even more innovative uses of WebAssembly in the future.
If you're a web developer aiming to push the boundaries of what's possible on the web, exploring WebAssembly is a worthwhile endeavor. It might just be the key to unlocking the next level of web performance for your applications. | andylarkin677 |

1,917,368 | How To Deal With Side Effects | Dealing with side effects in React is crucial to ensuring your components behave correctly and... | 0 | 2024-07-10T08:29:27 | https://dev.to/ark7/how-to-deal-with-side-effects-5f22 | javascript, programming, tutorial, webdev | Dealing with side effects in React is crucial to ensuring your components behave correctly and efficiently. React provides several hooks and lifecycle methods to handle side effects.
Certain components in React need to interact with things outside themselves. These things can be anything from querying data from a server to finding/changing the position of the component on the webpage or even sending some data to a server when necessary. This interaction with the outside world is called a **side-effect**.
Though we are already familiar with rendering code and adding event handlers, it is not enough for all uses, like when you want to connect to your server and fetch messages to show to a user.
**Effects** let you run some code to synchronize your component as necessary, on rendering or a reactive/state value change rather than on a particular event.
Similar to how we have the _useState_ hook, React offers us a handy useEffect hook to use effects in our components.
Here's an overview of how to manage side effects in functional components using hooks and in class components using lifecycle methods:
If you run the code above, you do realize that the count in our wepage is inconsistenmt and it runs crazy, this implementation has a problem: _setInterval _is called every time the component renders, which will create multiple intervals and can cause performance issues.
This is where the useEffect hook swoops in to save us. We can wrap this calculation inside a useEffect hook to move it outside the rendering calculation. It accepts a callback function with all the calculations.
In the code above , we have added the useEffect function but the result from our page still runs crazy.
_useEffect_ is a hook that lets us perform side effects in function components. Here, we use it to set up an interval that increments the counter every second.
The _setInterval_ function runs the provided function (which increments counter) every 1000 milliseconds (1 second).
The return statement inside _useEffect_ is a cleanup function that clears the interval when the component is unmounted to prevent memory leaks.
## The dependency array
Effect Runs on Every Render: Without the dependency array, useEffect runs after every render.
This means that every time the component re-renders (which happens whenever the state or props change), a new interval is set up. This leads to multiple intervals being created, causing the counter to increment much faster than intended.
Fortunately, the second argument accepts an array of dependencies allowing the hook to re-render only when those dependencies are changed. So if you have a state variable and want to have some side-effect occur any time the state changes, you can use this hook and mention the state variable in the dependency array.
We pass an empty array in this example because we do not want the useEffect hook to run anytime other than the initial component render.
Here is how we pass an empty array.
In the code sample above, by including the dependency array,we ensure that the interval is set up only once when the component mounts and not on every render. However, it is crucial to add cleanup for the interval to prevent potential memory leaks or performance issues.
As seen now, our application counts seconds without being messy but we still have an issue with the counter updating twice every second though. That can be understood as a behavior caused by the React StrictMode.
In our code, every time the useEffect hook runs, a new setInterval is used. When the component is unmounted, setInterval is not stopped, it keeps incrementing. This unnecessary behavior can be prevented by clearing the interval when the component is unmounted and that is where the third part of our useEffect hook comes in - the cleanup function.
You can return a function from the callback in the useEffect hook, which will be executed each time before the next effect is run, and one final time when the component is unmounted. In this case, let us clean up the interval with a cleanup function.
**In our code provided above:**
useEffect is a hook that lets us perform side effects in function components. Here, it is used to set up an interval.
Inside useEffect, the setInterval function creates an interval that increments the counter state by 1 every 1000 milliseconds (1 second).
The const key = setInterval(...) line assigns the interval ID to a variable named key.
The **return statement **inside useEffect is a cleanup function that clears the interval when the component **unmounts**. This prevents memory leaks by ensuring that the interval is properly cleaned up.
The empty dependency array [] ensures that this effect runs only once, after the initial render of the component.
## NB
By including the cleanup function inside the useEffect, we ensure that the interval is properly cleared when the component is unmounted, preventing potential memory leaks and ensuring efficient use of resources.
This is a summary of how useEffect hook:
```
useEffect(
() => {
// execute side effect
return () => {
// cleanup function on unmounting or re-running effect
}
},
// optional dependency array
[/* 0 or more entries */]
)
```
## Cases where useEffect does not need to be used.
1. You do not need to use an effect if you are only calculating something based on the state during rendering. For a change in a component, due to a change in the props, you can calculate and set it during rendering.
2. You do not need effects for events. Code that runs when a component is displayed should be in effects, the rest should be in events.
3. You do not need an effect to reset the state based on a condition most of the time. You have learned about keys in React. Just like using a key on a list’s item, adding one to a component, based on the state on which it should be reset creates a unique version of that component for each change in the value of the state.
4. If you are having issues with managing your state and want to use an effect to update the state of a parent or some other non-child component, consider lifting the state. As we know, in React, the state flows in one direction, generally down the DOM. So the parents know of the data before passing it to the children. If multiple children are required to make use of a single state, it should be moved up to the parent that has all of the components that need it, instead of using escape hatches like an effect.
That has brought us to the end of our learning on useEffect in React.
In case of any questions let me know and we shall go through them one by one.
Happy hacking!

---
Sorte pode ser criada.
Ok, talvez essa frase seja um pouco *clickbait*.
Não existe uma fórmula mágica que faça com que você tenha.
Mas, existe uma estratégia que pessoas de sucesso tem aplicado há décadas. E que nós podemos tirar alguns aprendizados para nós também.
Mas, como isso se relaciona com trabalhar pra gringa ou engenharia de software?
Aumentando nosso radar de oportunidades. Seja para conseguir vagas com altos salários ($100/h+), trabalhar com tecnologias que temos interesse, sair do país. Há uma infinidade de possibilidades onde ter mais sorte pode nos ajudar.
Hoje vamos discutir sobre isso.
## 📣 O que esperar do artigo
- Quais são os tipos de sorte
- Como criar cenários que favoreçam a sorte vir para você
## 🎰 A primeira definição de sorte
Sorte binária. Ou você tem sorte, ou não tem.
Essa é a primeira definição de sorte que temos em nossas vidas. Andamos na rua, achamos uma nota de dez reais e ficamos felizes, com sorte. (Lembram-se quando 10 reais comprava 3 chocolates de 170g na Americanas e as vezes até uma coca também?)
Temos aqui também a questão de privilégio. Você pode nascer numa família rica, ou ter que batalhar desde cedo. Uma loteria figurativa.
Ao acreditar apenas na sorte binária, pode ser uma situação confortante. A gente se conforma com o fato de que nunca seremos herdeiros. Que a nossa falta de sucesso não é nossa culpa, mas um problema das nossas circunstâncias.
**Porém, esse é um cenário que nos limita. Pois podemos acreditar que nossa falta de sucesso é por uma questão de sorte.**
## 🍀 Quatros tipos de sorte
[Naval Ravikant resume a sorte em quatro situações diferentes](https://www.navalmanack.com/almanack-of-naval-ravikant/how-to-get-lucky) (tradução livre por mim):
1. Esperar que a sorte te encontre.
2. Persistir e continuar tentando até que você tropece nela.
3. Preparar a mente e saber oportunidades que outros não percebam.
4. Se tornar o melhor naquilo que você faz. Continuar se esforçando até que isso seja verdade. Oportunidades irão te perseguir. Sorte se torna o seu destino.
Analisando mais a fundo, podemos separar estes cenários usando quatro variáveis: **passivo vs ativo** e **geral vs individual** ([definição feita pelo swyx](https://www.swyx.io/create-luck)).
Imagine uma planta. Ela vive sua vida inteira em um lugar, e controla extremamente pouco sobre seus arredores. Ela não se arrisca. Se encaixa perfeitamente no primeiro cenário. Qualquer sorte que aconteça a ela é acidental.
Agora, imagine uma pessoa apostando em um cassino. Ela pode apostar mil vezes, e não ganhar nenhuma vez. Mas, pode ser que ela ganhe alguma coisa depois de tentar 5 mil vezes. Mas, não foi pelo esforço dela. E simplesmente por tentar demais. Se encaixa no segundo cenário.
Para o terceiro cenário, vamos imaginar um engenheiro de software. Essa pessoa fala inglês, tem experiência de mercado numa stack relevante, e um LinkedIn atualizado. Um recrutador o contata para fazer uma entrevista, ele passa. É o terceiro cenário: a oportunidade o encontrou e ele estava preparado.
Agora, vamos pegar outro engenheiro de software. Além de ter tudo que o anterior fazia, ele também tem um blog pessoal onde publica sobre tecnologias que aprende. Participa de discussões em fóruns e comunidades. E faz palestras quando tem oportunidade. Nesse exemplo, um gerente de uma empresa o contata diretamente convidando-o para trabalhar com ele.
Para o último caso, a chance veio pelo simples fato da pessoa existir e fazer aquilo que ela gosta. E se aprimorar cada vez mais em suas habilidades. **A oportunidade se tornou seu destino.**
O que isso nos diz:
1. Para aumentar nossos momentos de sorte, precisamos nos **arriscar mais.** Fazer coisas que nos coloquem em chance de algo bom acontecer.
2. Para que as oportunidades sejam bem aproveitadas, devemos estar sempre **bem preparados** para quando ela aconteça.
## 🎯 Estratégia
**Queremos fazer com que a nossa sorte seja magnética**. 🧲
Para isso, precisamos definir uma estratégia que, no longo prazo, nos levem para o quarto cenário. Que façam com que oportunidades venham até nós, e que estejamos preparados para ela.
Isso pode variar dependendo da sua profissão. Nesse artigo, vou focar em engenheiros de software.
Existem várias maneiras de você conseguir isso. Essa imagem mostra apenas alguns deles. Existem várias outras formas que não incluí, como contribuir para *open-source* e participar de comunidades.
O principal ponto é **fazer coisas em público, conhecer pessoas, e ter um histórico digital do seu trabalho.**
## 🌟 TL;DR
- Pessoas de sucesso vêm aplicando técnicas há décadas para ter mais sorte. Como? Sendo bom no que faz e tendo um histórico do seu trabalho
- Sorte é uma mistura entre oportunidade e preparação. Use hábitos e estratégias na sua vida que te empurrem nessa direção. Construa seu caráter e reputação de maneira íntegra, em público, e as oportunidades virão até você.
- Indiferente do que você faz, o importante é ter um viés de ação. Faça coisas ativamente, e seja intencional sobre como você gasta o seu tempo.

1,917,381 | j-Exec — Total.js | j-Exec is part of the jComponent library from Total.js. You can find more information about j-Exec on... | 0 | 2024-07-09T14:17:06 | https://dev.to/palo/j-exec-totaljs-2bo4 | frontend, ui, totaljs, development | j-Exec is part of the jComponent library from Total.js. You can find more information about j-Exec on [componentator.com](https://componentator.com/components/j-exec/) or [GitHub](https://github.com/totaljs/components/tree/master/j-Exec).
This component is singleton and works for the whole HTML document, where it is used. After adding a class _exec_, _exec2_, or _exec3_ to the element this component captures a click event (or double-click and right-click, depending on usage) and executes a method that you define.
## How to use j-Exec
As first step you have to know how to use jComponent library. I wrote about it in my previous blog, so for more information please read this [blog post](https://dev.to/palo/jcomponent-totaljs-1m26).
**Initialization**
It is very straightforward to use j-Exec in your applications and here I show you an example.
First of all, you have to initialize it in your code. A good practice is to initialize your singleton components on the top of your document (I have them as the first thing in my _body_ element). It is clear and easy to debug when you know where to look for your components.
```html
<ui-component name="exec"></ui-component>
```
After this, you can use j-Exec on every element you want as many times as you need.
**Usage**
To make j-Exec work it is important to add two things to your element. You have to add class exec to a particular element and attribute _data-exec_, which must contain the method you want to execute.
Example:
This example will include code with plugins, so if you want more information about them, please read my [previous blog](https://dev.to/palo/totaljs-ui-library-2c3n) or [documentation](https://docs.totaljs.com/components/40d03002xw50c/) (or the example on [componentator.com](https://componentator.com/components/j-exec/) is without plugins).
```html
<ui-plugin path="example">
<div class="exec" data-exec="?/click">Click</div>
</ui-plugin>
```
After clicking on our element (in this case, the _div_ element with the text _Click_), the method _click_ from our PLUGIN will be executed.
```javascript
PLUGIN('example', function(exports) {
exports.click = function(element, event) {
console.log('Click');
};
});
```
This is JavaScript PLUGIN with one method _click_. After executing this method word click will appear in our console. As you can see you can catch the_ element_ which was clicked and the _event_ which invoked this method.
**Double-click and right-click**
If you want to capture double click or right click you can use the same code as in the example above with two little changes in HTML code. These changes would be **class and attribute**.
**Double-click**
```html
<ui-plugin path="example">
<div class="exec2" data-exec2="?/click">Click</div>
</ui-plugin>
```
**Right-click**
```html
<ui-plugin path="example">
<div class="exec3" data-exec3="?/click">Click</div>
</ui-plugin>
```
## Redirect
j-Exec can be also used directly for redirecting. After clicking on an element with class exec will be executed method _REDIRECT()_.
Example:
```html
<ui-plugin path="example">
<div class="exec" data-href="home">Click</div>
</ui-plugin>
```
Clicking on our div element with the text _Click_ will execute method **REDIRECT('/home/')**. This method performs redirects to relative path **/home/**. If you want more information about this method, please read the [documentation](https://docs.totaljs.com/components/40d02001ra51c/#61b95001ob51c).
**Double-click and right-click**
Double-click and right-click work the same as in the example with invoking our method. We have to change class and attribute.
**Double-click**
```html
<ui-plugin path="example">
<div class="exec2" data-href2="home">Click</div>
</ui-plugin>
```
**Right-click**
```html

1,917,373 | The Importance of React in Web Development | React, developed and maintained by Facebook, has become one of the most popular JavaScript libraries... | 0 | 2024-07-09T13:58:11 | https://dev.to/patrick_chibueze_e2567f25/the-importance-of-react-in-web-development-1dn4 | react, webdev, reactjsdevelopment, programming | React, developed and maintained by Facebook, has become one of the most popular JavaScript libraries for building user interfaces, particularly single-page applications. Since its release in 2013, React has revolutionized web development with its component-based architecture, virtual DOM, and efficient rendering. This guide will explore the significance of React in modern web development and provide code examples to illustrate its core features.
## Key Features of React
- Component-Based Architecture
React promotes a component-based architecture where the UI is divided into reusable, self-contained components. This modularity makes development more manageable and scalable.
Example: A Simple React Component
```jsx
import React from 'react';
function Greeting(props) {
return <h1>Hello, {props.name}!</h1>;
}
export default Greeting;
```
In this example, JSX syntax is used to create an `h1` element rendered to the DOM.
- Unidirectional Data Flow
React enforces a unidirectional data flow, making it easier to track data changes and debug applications. Data flows from parent components to child components through props.
Example: Passing Data with Props
```jsx
import React from 'react';
function Welcome(props) {
return <h1>Welcome, {props.user}!</h1>;
}
function App() {
return <Welcome user="Patrick" />;
}
export default App;
```
In this example, the `App` component passes the `user `prop to the `Welcome `component.
## Advantages of Using React
- Performance
React's virtual DOM and efficient diffing algorithm significantly enhance performance, especially for applications with complex UIs and frequent updates.
- Developer Experience
React's component-based architecture and JSX syntax streamline the development process, making it easier to write, read, and maintain code. The extensive ecosystem, including tools like React Developer Tools, further enhances the developer experience.
- Cross-Platform Development
With React Native, developers can use the same React principles and codebase to build mobile applications for iOS and Android, reducing development time and effort.
- Community and Ecosystem
React boasts a vast and active community, providing numerous libraries, tools, and resources. This extensive ecosystem accelerates development and fosters innovation.
## Real-World Applications of React
React powers some of the most popular and high-performing web applications, including:
- Facebook: React is used extensively across Facebook's web platform.
- Instagram: The photo-sharing app leverages React for its web interface.

1,917,375 | Optimizing Performance in Full-Stack Applications | Optimizing performance in full-stack applications is crucial for ensuring a smooth user experience,... | 0 | 2024-07-09T14:02:44 | https://dev.to/chariesdevil/optimizing-performance-in-full-stack-applications-41e2 | app, developer, fullstack | Optimizing performance in full-stack applications is crucial for ensuring a smooth user experience, reducing server load, and improving overall efficiency. This involves a combination of front-end and back-end optimizations, efficient database management, and strategic use of caching. In this article, we'll explore various techniques to optimize full-stack applications.
Front-End Optimization
1. Minimize HTTP Requests
HTTP requests significantly impact page load time. Reducing the number of requests can be achieved by combining CSS and JavaScript files, using CSS sprites for images, and inlining small assets directly into the HTML.
2. Optimize Images
Images are often the largest files on a webpage. To optimize them:
Compression: Use tools like TinyPNG or ImageOptim to reduce file size without losing quality.
Responsive Images: Serve different image sizes based on the user's device using the srcset attribute.
Lazy Loading: Load images only when they enter the viewport with the loading="lazy" attribute.
3. Minify and Bundle Assets
Minifying CSS, JavaScript, and HTML files removes unnecessary characters, reducing file size. Tools like UglifyJS for JavaScript and CSSNano for CSS can help. Bundling multiple files into a single file reduces the number of HTTP requests.
4. Use a Content Delivery Network (CDN)
A CDN stores copies of your website's static assets in multiple geographic locations, reducing latency and speeding up load times for users across the globe. Popular CDNs include Cloudflare, Akamai, and Amazon CloudFront.
5. Implement Browser Caching
Leverage browser caching to store static resources on the user's device. This reduces the need to re-download assets on subsequent visits. Set appropriate cache headers for static files, like images, CSS, and JavaScript.
Back-End Optimization
1. Optimize Database Queries
Inefficient database queries can slow down your application. To optimize them:
Indexing: Properly index your database tables to speed up query performance.
Query Optimization: Use tools like EXPLAIN (in SQL databases) to analyze and optimize your queries.
Avoid N+1 Queries: Fetch related data in a single query to avoid multiple database hits.
2. Use Caching Strategically
Caching can dramatically improve performance by storing frequently accessed data in memory. Techniques include:
In-Memory Caching: Use systems like Redis or Memcached to cache database queries, API responses, and session data.
HTTP Caching: Set cache headers like ETag, Last-Modified, and Cache-Control to control browser and proxy caching.
3. Optimize Server-Side Code
Efficient server-side code is essential for fast responses:
Asynchronous Processing: Use asynchronous programming models (e.g., Node.js) to handle I/O operations without blocking the main thread.
Load Balancing: Distribute incoming traffic across multiple servers to avoid overloading a single server.
Optimize Middleware: Use lightweight and efficient middleware for routing and processing requests.
Database Management
1. Choose the Right Database
Select a database that fits your application's needs. Relational databases (e.g., PostgreSQL, MySQL) are suitable for structured data, while NoSQL databases (e.g., MongoDB, Cassandra) are better for unstructured data and high scalability.
2. Optimize Schema Design
A well-designed schema improves query performance and reduces redundancy:
Normalization: Eliminate redundant data by dividing tables into smaller, related tables.
Denormalization: In some cases, denormalization (storing redundant data) can improve read performance at the cost of write performance.
3. Monitor and Tune Performance
Regularly monitor your database performance and tune it as needed:
Query Monitoring: Use tools like New Relic or Datadog to monitor and analyze query performance.
Resource Allocation: Ensure your database has sufficient CPU, memory, and storage resources.
Caching Strategies
1. Client-Side Caching
Store data on the client side to reduce server load and improve responsiveness:
Service Workers: Use service workers to cache static assets and API responses, enabling offline capabilities.
Local Storage and IndexedDB: Store data locally in the browser for faster access and offline support.
2. Server-Side Caching
Implement server-side caching to reduce database load and speed up responses:
**Page Caching:** Cache entire pages for anonymous users to serve them quickly without hitting the database.
**Fragment Caching:** Cache parts of a page (e.g., user profile data) to reduce database queries.
## Performance Monitoring and Testing
**1. Use Performance Monitoring Tools**
Tools like Google Lighthouse, WebPageTest, and GTmetrix provide insights into your application's performance, highlighting areas for improvement.
**2. Load Testing**
Simulate heavy traffic to identify bottlenecks and optimize your application. Tools like Apache JMeter and Locust can help perform load testing.
**3. Continuous Performance Testing**
Integrate performance testing into your CI/CD pipeline to catch performance regressions early. Use tools like Jenkins, Travis CI, or GitHub Actions to automate performance testing.
## Conclusion
Optimizing performance in full-stack applications requires a holistic approach, addressing both front-end and back-end aspects. By minimizing HTTP requests, optimizing images, leveraging caching, and ensuring efficient database management, you can significantly improve your application's performance. Regular monitoring and testing are essential to maintaining optimal performance as your application evolves. Implement these techniques to deliver a fast, responsive, and scalable full-stack application. | chariesdevil |

After using tmux for more than a decade, I’ve recently moved away from it and switched to using the multiplex features in wezterm. One of my favorite plugins for tmux is [tmux-thumbs](https://github.com/fcsonline/tmux-thumbs). This allowed me to write patterns using regex and press a shortcut to highlight those patterns. It would give me a set of quick keys I could type that would then either copy the text to my clipboard or paste it to the command line. This comes in very handy when using kubectl and dealing with pod names.
Wezterm has a similar feature called QuickSelect. The following config will create a LEADER-f shortcut for selecting the string and pasting it into the command prompt and LEADER-F to copy it to the clipboard.
```
local config = wezterm.config_builder()
config.keys = {
{
key = "f",
mods = "LEADER",
action = act.QuickSelectArgs({
label = "paste",
action = wezterm.action_callback(function(window, pane)
local selection = window:get_selection_text_for_pane(pane)
pane:paste(selection)
end),
}),
},
{ key = "F", mods = "LEADER", action = act.QuickSelect },
}
config.quick_select_patterns = {
"[a-z]+(?:-[a-z0-9]+)+-[a-z0-9]+",
}
return config

<figcaption>The part I struggle with the most: Automation and CI/CD</figcaption>
</figure>
This part of the challenge was both the most enlightening and the most challenging. <u>_Automating deployments and managing infrastructure as code were entirely new concepts for me, but they have now become some of the most valuable skills I’ve gained._</u>
**Steps Involved:**
1. **Learning Terraform**: I spent around 16 hours going through tutorials and documentation to get a solid understanding of Terraform. Writing infrastructure as code (IaC) to manage my AWS resources was a game-changer. Instead of manually creating and managing resources through the AWS console, I could now define my entire infrastructure in code and deploy it with a single command.
2. **Creating Terraform Configurations**: I created separate Terraform configurations for my frontend and backend resources. This included S3 buckets, CloudFront distributions, API Gateway, DynamoDB tables, and Lambda functions. The process was iterative – I often had to destroy and recreate resources to fix configuration issues.
3. **Setting Up CI/CD Pipelines**: Using GitHub Actions, I set up workflows to automate the deployment process. One workflow handled the frontend, updating the S3 bucket with new website files whenever I pushed changes to my GitHub repository. Another workflow managed the backend, deploying updated Lambda functions and API Gateway configurations.
### Challenges Faced:
1. **Infrastructure as Code**: Learning Terraform was like learning a new language. There were times when I had to completely rewrite my configurations because of a small mistake. However, the more I used it, the more I appreciated its power and flexibility.
**Solution:
https://www.youtube.com/watch?v=7xngnjfIlK4&ab_channel=DevOpsDirective**
2. **CI/CD Pipelines**: Setting up GitHub Actions was straightforward, but making sure the workflows ran smoothly was another story. I had to debug several issues related to permissions and environment variables. Automating the deployment of my infrastructure saved me countless hours and ensured consistency across deployments.
**Solution:
https://github.blog/2022-02-02-build-ci-cd-pipeline-github-actions-four-steps/**
3. **Email Integration with SES**: As part of the dynamic contact form, I integrated Amazon SES (Simple Email Service) to handle email submissions. This was a new challenge as I had to ensure the emails were sent correctly from my Lambda function, which required setting up proper IAM permissions and SES configurations.
**Solution:
https://www.youtube.com/watch?v=LhkXP9Oli7U&ab_channel=Coderjony**
### Lessons Learned:
- **Infrastructure as Code**: Gaining a deep understanding of AWS resources by configuring them with Terraform was immensely rewarding. It made managing my cloud infrastructure efficient and scalable.
- **CI/CD Pipelines**: Automating deployments with GitHub Actions streamlined my development process, making it easier to deploy changes confidently and quickly.
- **Email Integration**: Implementing Amazon SES for email functionality expanded my knowledge of AWS services and their integration.

1,917,480 | Fin Intercom vs GaliChat - The Best AI Assistant for your Business | GaliChat and Intercom's Fin are two AI-powered chatbots built to ease customer support by providing... | 0 | 2024-07-10T09:50:14 | https://dev.to/creativetim_official/fin-intercom-vs-galichat-the-best-ai-assistant-for-your-business-1c7d | ai, automation | [GaliChat](https://www.galichat.com/) and [Intercom's Fin](https://www.intercom.com/drlp/ai-chatbot) are **two AI-powered chatbots built to ease customer support by providing automated and accurate responses to user queries.**
While both are based on advanced AI language models, they differ in their specific features, customization options, and integration capabilities.
## ⚙️ Chatbot Setup
**GaliChat** has a quick and user-friendly setup process, with only three simple steps to get the chatbot up and running on a website.
###### _[Source](https://www.galichat.com/)_
Users can add their website links or files, train the chatbot with their relevant data (knowledge center, documentation, internal information, training notes), and integrate it into their website.
###### _[Source](https://www.galichat.com/)_
This no-code approach helps businesses to deploy a custom chatbot in just minutes.
In contrast, setting up **Intercom's Fin** may involve a more complex process, as it relies on integrating with Intercom's existing tools and workflows.
###### _[Source](https://www.intercom.com/help/en/articles/7120684-fin-ai-agent-explained)_
While Fin uses Intercom's customer data and knowledge base, it may require additional setup time in comparison with GaliChat's streamlined approach.
## 🤝 Integrations
**Fin** integrates with Intercom’s suite of tools, including inbox, ticketing, messenger, and reporting tools, ensuring a more complete and unified experience for support teams and customers.
###### _[Source](https://www.intercom.com/help/en/articles/7120684-fin-ai-agent-explained)_
Fin also features omnichannel conversations across email, phone, live chat, SMS, WhatsApp, Facebook, and Instagram, all routed to a single inbox for efficient prioritization and resolution.
Known for its simplicity, **GaliChat** does not currently support other integrations as it addresses to businesses who are looking for a simple but functional AI website chatbot.
## 🎨 Chatbot Customization Options
In terms of functionality, **GaliChat** provides a no-code platform that helps businesses quickly set up an AI chatbot customized to their specific needs, which can be trained on the company's own website data and content. This allows for highly personalized interactions and accurate responses to customer questions.
###### _[Source](https://www.galichat.com/)_
In terms of branding, GaliChat can also be customized to match the company’s brand and differentiate it from competitors. Users can personalize the chatbot's appearance, including changing its name and icon, and customize the messenger interface.
**Fin AI Agent** offers even more customization options to align with brand identity. The platform allows for customizing Fin's behavior through Workflows, enabling businesses to set specific audience targeting, configure auto-close parameters, and customize closing messages.
###### _[Source](https://www.intercom.com/help/en/articles/7837525-customizing-fin-ai-agent-in-the-messenger)_
Additionally, Fin provides control over content sources, allowing users to specify whether they should use only custom answers or blend them with AI-generated responses.
## 🗣 Multilingual Support
**GaliChat** offers multilingual support, being capable of understanding and responding in over 50 languages. This makes it perfect for businesses with a global customer base.
###### _[Source](https://www.galichat.com/)_
**Intercom's Fin** also provides multilingual capabilities, though the exact number of supported languages is not specified. Intercom recommends creating separate help center articles and chat flows for each language, which can be a bit more time-consuming to set up and maintain compared to GaliChat's more streamlined approach.
## 💰 Pricing
Galichat.com offers a pricing model that is more budget-friendly, appealing to small and medium-sized enterprises with its affordable rates and scalable options.
In contrast, Intercom's Fin, while providing a more comprehensive suite of advanced features such as sophisticated automation and analytics, tends to come at a higher price point.

Redis is a versatile database that can solve many problems when scaling a Fintech.
## Cache
The first problem that Redis solves is to be able to cache data.
You can use cache to reduce the workload from external APIs or the main database.
We use it to cache slow/expensive external APIs, OAuth2 tokens, and account balances.
## Distributed Lock
We use Redis to create distributed locks to make concurrency safe in some scenarios like updating the balance of an account.
[A simple distributed lock implementation using Redis](https://dev.to/woovi/a-simple-distributed-lock-implementation-using-redis-445c)
## Message Queue
We use Redis to create a message queue and async batch processing using BullMQ
## Pub/Sub
We use Redis to create a publisher/subscriber to make our application real-time using WebSockets and GraphQL Subscriptions.
## Rate Limiting
We also implement rate limiting using Redis to avoid DDoS attacks, Credential stuffing, Brute force attacks, and Data scraping.
## In Conclusion
Redis is a versatile database that can be used in many scenarios to solve many problems as you scale.
If you are not using Redis, it could be a good addition to your tech stack

<p>Last week, I participated in <a href="https://www.opensouthcode.org/" rel="nofollow noopener">Open South Code</a> in Malaga, explaining the creative process behind <a href="https://comicss.art/">comiCSS</a>. As part of the conference, there was a kid's event, and I volunteered for it.</p>
<p>The organizers asked me to do something related to my talk, and that's how a new CSS utility-class library was born: <a href="https://alvaromontoro.com/sansjs/demos/batman-comic-css/">batman-comic.css</a>. This library is for anyone willing to create Batman comic strips.</p>
<p>Since its creation in the past two weeks, we've used the library in two kids' conferences. The library allows children to play with HTML and quickly see the power of CSS —even when this may not be the best way to use it. <b>Children enjoy seeing how you can add text or replace some HTML classes, and a completely different comic pops up instantly</b>.</p>
<h2>Origin</h2>
<p>The original idea for the library came from "<a href="https://comicss.art/comics/50/">Wedding Invitation</a>," a comiCSS cartoon strip featuring Batman and Robin arguing about how <del>Bruce Wayne</del> Batman can be a penny-pincher:</p>
<p>I liked that comic idea and wanted to streamline the process, even if I didn't have anything planned with these characters. Simplifying the process would provide more consistency (and speed) to comiCSS. Apart from this library, I've been working on something on the side. But I digress.</p>
<p>Creating a CSS library to generate the characters seemed simple for the event (I only had a few days to prepare the activity), as I already had many facial expressions done.</p>
<p>The instant gratification of HTML and CSS would also go a long way with the kids. They were going to code and see how the comic updated immediately. And so it went.</p>
<h2>The Library</h2>
<p>There is a <a href="https://alvaromontoro.com/sansjs/demos/batman-comic-css/">documentation page online</a> with all the details, colors, and classes —and <a href="https://alvaromontoro.com/sansjs/demos/batman-comic/">another one in Spanish</a> that I created for the children's events.</p>
<p>The characters' drawings are in CSS using a single HTML element, its pseudo-elements, and many gradients. This simplicity makes it easy to add a character to the comic. For example, this will add a smiling Batman:</p>
```html
<div class="batman"></div>
```
<p>Then, there are classes to set different eyes and mouths. <b>All the characters have the same face-expression classes that generate up to 864 different combinations</b> (12 eye combinations * 24 mouth combinations * 3 additional features). For example, this will add an angry Batman:</p>
```html
<div class="batman eyes-angry mouth-angry"></div>
```
<p>These are the list of classes that each character can have. Some of them can be combined with others (noted as "combinable")</p>
<ul>
<li>Eyes
<ul>
<li><code>eyes-no</code>: No eyes.
<li><code>eyes-think</code>: Eyes slightly closed from the top.
<li><code>eyes-doubt</code>: Eyes slightly closed from top to bottom.
<li><code>eyes-sad</code>: Eyes skewed to look sad (towards the inside).
<li><code>eyes-angry</code>: Eyes skewed to look angry (towards the outside).
<li><code>eyes-suspicious</code>: The left eye thinks, and the right eye is angry.
<li><code>eyes-surprise</code> (combinable): larger eyes.
<li><code>eyes-shock</code> (combinable): the right eye is more prominent.
</ul>
</li>
<li>Mouth
<ul>
<li><code>mouth-no</code>: No mouth.
<li><code>mouth-sad</code>: Frawned mouth.
<li><code>mouth-angry</code>: see mouth-sad.
<li><code>mouth-talk</code>: Mouth with the character talking.
<li><code>mouth-round</code>: a circle
<li><code>mouth-whisper</code>: a small oval
<li><code>mouth-right</code> (combinable): moves the mouth slightly to the right side.
<li><code>mouth-left</code> (combinable): moves the mouth slightly to the left side.
<li><code>mouth-to-right</code> (combinable): skews the mouth towards the right.
<li><code>mouth-to-left</code> (combinable): skews the mouth towards the left.
</ul>
</li>
<li>Others
<ul>
<li><code>blush</code>: a reddish glow in the visible part of the face.
<li><code>scare</code>: a blueish glow in the visible part of the face.
<li><code>shame</code>: a (lighter?) reddish glow in the visible part of the face.
</ul>
</li>
</ul>
<p>I'm not 100% sold on these class names. I developed the library in a "quick and dirty" way and may likely change the names and default values to bring more consistency.</p>
<p>Additionally, <b>each character uses different CSS custom properties to define their colors</b> (<a href="https://alvaromontoro.com/sansjs/demos/batman-comic-css/">check the documentation for more information</a>), and <b>the comic strip panels use CSS Grid for layout</b> for easy customization.</p>
<h2>Examples</h2>
<p>Here are some examples of what can be created with the library as it is right now (quite limited):</p>
<p>A couple of them are the same idea implemented differently. I needed more ideas, but these examples should showcase the library options.</p>
<h2>What's next?</h2>
<p>As I mentioned above, I might use the library myself to generate new CSS comics, but in all honesty, I still don't know how it will apply.</p>
<p>I may reuse it in events —especially with children and beginners, who seem more impressed by their capabilities and what they can achieve with a bit of code. But it will require some updates:</p>
<ul>
<li>New characters (Superman? Bane? Joker? Catwoman?)</li>
<li>New facial expressions</li>
<li>Correct facial expressions (Robin is a bit buggy)</li>
<li>Adding props</li>
</ul>
<p>A future step will be to share the library on GitHub and open it to the world, allowing others to use it and contribute new content (especially props).</p>

Experiencing the Automatic Repair Blue Screen, also known as the **Blue Screen of Death (BSOD)**, can be frustrating. This issue can arise from various causes, such as **sudden power loss**, **Windows registry collapse**, **corrupted boot or system files**, **hardware failures**, and **software conflicts**. Below is a comprehensive guide to solutions for different issues that lead to BSOD.
# Accessing Advanced Options
To access the solutions below, navigate to:
Advanced options > Troubleshoot > Advanced options
## 1. Startup Repair
**Startup Repair ** prepares your computer, operating system (OS), hardware, or software for operation. This process, often called booting, loads the OS into the computer's main memory or RAM. On a PC, you typically see the initial Windows or Mac desktop screen after booting.
Rebooting your computer is sometimes necessary to resolve issues. The shortcut key for rebooting is **Ctrl + Alt + Del.**
**Bootloader:** A program that runs before the OS starts, loading the OS kernel into memory. It is typically stored on the device's firmware (BIOS/UEFI).
**Commands for Bootloader and BIOS Information:**
Bootloader Information:
```
bcdedit
```
BIOS Information:
```
wmic bios get /format:list
```
Accessing Boot Menu:
For Lenovo laptops, press **F12** repeatedly at the Lenovo logo during bootup.
# 2. Uninstall Updates
Recently installed Windows updates can sometimes cause issues. Uninstalling these updates might resolve the BSOD.
# 3. Command Prompt Solutions
**Method 1:** Using Bootrec and System Tools
Move to the Windows Installation Drive:
```
C:
```
Create a New Master Boot Record (MBR):
```
bootrec /fixmbr
```
Create a New Boot Sector:
```
bootrec /fixboot
```
Scan Disks for Windows Installations:
```
bootrec /scanos
```
Check Disk Utility (Check and repair disk errors):
```
chkdsk /f /r c:
```
System File Checker Tool (Scan and replace protected system files):
```
sfc /scannow
```
Summarized Commands:
```
bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
chkdsk /f /r c:
sfc /scannow
```
**Method 2:** Windows Registry Repair
The Windows Registry is a centralized database storing configuration settings and options for both the OS and applications. Backups of the registry are stored in the **regback** folder.
(Note: This works only if automatic registry backup has been enabled before)
Commands:
```
cd windows/system32/config
MD backup
copy "." backup
cd regback
copy "." ..
```
# 4. System Restore
System Restore acts as a **"Time Traveling Machine"**, helping to protect and repair your computer's software by creating restore points. These points can be created manually or automatically by Windows before significant events, such as installing software or updates.
Restore points are snapshots of your computer's system files, installed applications, Windows registry, and system settings at a particular point in time.
(Note: System Restore does **not** affect personal data but will uninstall any software updates or drivers installed after the chosen restore point.)
# Conclusion
By following these solutions, you can resolve various issues that cause the Automatic Repair Blue Screen (BSOD) and restore your computer to normal functioning. Remember to back up important data regularly to prevent data loss during such issues.

Today and all the other days are where I'll suck, I'll still dedicate the same amount of time to read a day, but the content might be less :D since even if a formula is proven, it's better to try and disprove it too. So I'll bribe you with a meme from reddit.
#### A mini review for vectors
1. An array of numbers (Computer Science)
2. An array with direction and magnitude (Physics)
3. An object that obeys addition and scaling (Mathematics)
## Chapter 2 (Linear Algebra)
### Examples of Vectors
1. Geometric vectors
2. Polynomials
3. Audio
4. Elements of real numbers
#### Why?
The simple explanation is, all four examples obey the mathematical definition that these values can be added and becomes a new set of vector.
## Vector Mindmap
The tl;dr:
1. Matrix are composed of vectors and represents system of linear equations
2. System of linear equations can solve matrix inverse by using gaussian eliminations
3. Vector are the properties of linear independence, which is explained alongside linear/affine mapping in Chapter 12 Classifications
## System of Linear Equations
### Why should you know system of linear equations?
The simple flow is if a problem can be transformed to system of linear equations, then that problem can be solved using linear algebra.
Though there is a caveat that the amount of equations must be the same as the amount of unknown variables (Commonly... I'll explain this later on)
#### Example
##### No solutions
{% katex %}
\begin{align*}
(1) \quad & x_1 + x_2 + x_3 = 3 \\\
(2) \quad & x_1 - x_2 + 2x_3 = 2 \\\
(3) \quad & 2x_1 + 3x_3 = 1
\end{align*}
{% endkatex %}
Adding (1) and (2):
{% katex %}
\begin{align*}
(x_1 + x_2 + x_3) + (x_1 - x_2 + 2x_3) &= 3 + 2
\end{align*}
\\\
\begin{align*}
2x_1 + 3x_3 &= 5
\end{align*}
{% endkatex %}
This contradicts (3):
{% katex %}
\begin{align*}
2x_1 + 3x_3 &= 1
\end{align*}
{% endkatex %}
##### Found Solution
{% katex %}
\begin{align*}
(1) \quad & x_1 + x_2 + x_3 = 3 \\\
(2) \quad & x_1 - x_2 + 2x_3 = 2 \\\
(3) \quad & x_2 + x_3 = 2
\end{align*}
{% endkatex %}
Subtracting (1) and (2) -> (4):
{% katex %}
\begin{align*}
(4) \quad & 2x_2 - x_3 &= 1
\end{align*}
{% endkatex %}
Subtracting (3) and (4):
{% katex %}
\begin{align*}
(3) \quad & x_2 + x_3 = 2 \\\
(4) \quad & 2x_2 - x_3 = 1
\end{align*}
{% endkatex %}
Subtracting (3) and (4):
{% katex %}
\begin{align*}
-3x_3 = -3 \\\
\therefore x_3 = 1
\end{align*}
{% endkatex %}
With x3 found, it's just a matter of replacing the known equations and we'll find
{% katex %}
\begin{align*}
x_1 = 1,
x_2 = 1,
x_3 = 1
\end{align*}
{% endkatex %}
### Surprise Quiz!
There's one more problem. There's no contradictions and (technically) there's an answer. But what's more fun is, try and see what makes this problem difficult to solve by creating a question yourself!
{% katex %}

## Three base concepts of matrices
1. Additions and subtractions. The rule is the row and column of both matrix are the same.
{% katex %}
\begin{align*}
A_{mn} + B_{mn} &= C_{mn}
\end{align*}
{% endkatex %}
2. Multiplication (Dot Product). The rule is the number of columns of the first matrix (In this case A) needs to have the same value as the row of the second matrix (In this case B).
{% katex %}
\begin{align*}
A_{mn} \cdot B_{nk} &= C_{mk}
\end{align*}
{% endkatex %}
The result will return a new matrix with the size of (row A x Column B)
3. The Identity Matrix
A NxN-matrix with the main diagonal being filled with 1 while the rest are zeros.
{% katex %}
I_3 = \begin{pmatrix}
1 & 0 & 0 \\\
0 & 1 & 0 \\\
0 & 0 & 1
\end{pmatrix}
{% endkatex %}
The main diagonal is when the row and column index is the same. So row 1 column 1, row 2 column 2, etc.
## Properties of Matrices
Much like the base concepts, there are three properties described in the book before we delve into Inverse and Transpose.
### Associativity
{% katex %}
\forall A \in \mathbb{R}^{m \times n}, \;
B \in \mathbb{R}^{n \times p}, \;\\\
C \in \mathbb{R}^{p \times q} \; : \; (AB)C = A(BC)
{% endkatex %}
Don't be scared or annoyed by these symbols! This just means for all (V) A, B, and C that belongs to real numbers (R) with the dimensions of mxn,nxp,pxq respectively will create the equation.
P.S. If you weren't scared or annoyed, congratulations you're not me.
### Distributivity
{% katex %}
\forall A,B \in \mathbb{R}^{m \times n}, \;\\\
C,D \in \mathbb{R}^{n \times p} \;\\\
: (A+B)C = AB+BC\\\
: A(C+D) = AC+CD
{% endkatex %}
Much like scaling the matrix, when there's both addition/subtraction along side multiplication, the multiplication is distributed throughout the addition/subtraction.
### Multiplication with identity matrix
{% katex %}
\forall A \in \mathbb{R}^{m \times n}\\\
: I_{m \times m} A_{m \times n} = A_{m \times n} I_{n \times n} = A_{m \times n}
{% endkatex %}
When a matrix is multiplied by an identity matrix, the resulting matrix won't change. The same goes for an identity matrix multiplied by a matrix, the result will not change the shape nor the values of the matrix multiplied.

1,917,493 | The Hidden Power of the Box Model: What Every Frontend Dev Must Know | As the developer of flitter.dev, a rendering engine framework, I often find myself explaining the... | 0 | 2024-07-09T14:51:34 | https://dev.to/moondaeseung/the-hidden-power-of-the-box-model-what-every-frontend-dev-must-know-4ba2 | As the developer of [flitter.dev](flitter.dev), a rendering engine framework, I often find myself explaining the intricacies of how browsers and rendering engines work. This article aims to provide a comprehensive overview of the box model, its implementation in browsers, and how similar concepts are used in other frameworks.
## The Box Model and Browser Rendering
Browser rendering engines use the Box Model as the foundation for constructing web page layouts. When we write HTML tags, the browser parses them to create a Render Tree. Examining the class inheritance relationships of the instances that make up this tree, we find that the superclass is named RenderBox. Most HTML elements are parsed into instances of classes that inherit from RenderBox.
Key characteristics of the Box Model include:
1. **Area Distinction**: Elements are separated into box units.
2. **Spacing Control**: Margins and padding allow for adjustment of space between content.
3. **Layout Alignment**: Elements are aligned either horizontally or vertically.
4. **Tree Structure**: Boxes can contain other boxes, resulting in an overall tree structure.
The Box Model is particularly useful for displaying content. Books, magazines, newspapers, and websites primarily arrange content horizontally or vertically, and parent-child paragraph structures are easily represented. However, games and 2D/3D graphic images are challenging to resolve with the Box Model. These elements are difficult to divide into box shapes, requiring separate definitions for interaction units.
Browsers leverage the Box Model to help position elements as desired using only HTML and CSS. Consider the scenario of creating a desktop application without a browser engine. You would need to construct the Render Tree yourself, calculate coordinates for element layouts based on the hierarchical structure, determine which element was triggered by an event at (x, y) coordinates, and implement a hitTest() method for each Render Tree element to decide whether to activate event handlers.
For mobile apps that don't use browsers, frameworks perform these tasks. For instance, Google's cross-platform framework Flutter generates RenderObject instances (which inherit from RenderBox) for each widget. When the root object calls for layout, it calculates the positions of its children and passes coordinate information to the graphics engine for painting on the screen.
## Data Visualization and the Box Model
Data visualization content like charts and diagrams often contains many elements that can be represented by the Box Model. Bar graphs, in particular, can be fully expressed using just the Box Model. However, certain graphic elements (e.g., curved or bent lines) are challenging to represent in HTML. Consequently, chart and diagram libraries typically use SVG or Canvas instead of HTML. This means that these libraries must perform the role of the browser, which is why creating charts and diagrams can be complex.
## Conclusion
Understanding the Box Model and how rendering engines work is crucial for web developers and those working on rendering frameworks. While the Box Model is powerful and widely applicable, it's important to recognize its limitations and know when alternative approaches are necessary. As we continue to develop flitter.dev and other rendering solutions, these foundational concepts remain at the core of our work. | moondaeseung | |

1,917,495 | Delete automatic assignment of Public IPv4 addresses to Amazon EC2 instances using the AWS Systems Manager Automation runbook. | I recently did something similar using AWS Config -> Amazon EventBridge -> AWS Lambda in... | 0 | 2024-07-11T07:49:47 | https://dev.to/nishikawaakira/delete-automatic-assignment-of-public-ipv4-addresses-to-amazon-ec2-instances-using-the-aws-systems-manager-automation-runbook-15h8 | aws, automation |
I recently did something similar using AWS Config -> Amazon EventBridge -> AWS Lambda in [another article](https://dev.to/nishikawaakira/automatically-remove-automatic-ipv4-address-assignment-to-amazon-ec2-instances-12fl). In this case, I would like to use Automation runbook in AWS Systems Manager to delete the public IPv4 addresses of the EC2 instance automatically.
I would like to tell you that you don't need to have many programming skills to use Automation runbook to gain control.
## Create an AWS Systems Manager Automation runbook
Now, let's go and actually create AWS Systems Manager Automation runbook.
Initially, the following screen is opened. The Design tab is now selected.
You can create a runbook using the graphical interface in this way, or you can select the {} Code tab and edit YAML or JSON directly.
## Writing Automation runbook
When you visually add parts to Automation runbook, you will see YAML being described. You can also write Python within this YAML. Take, for example, [AWS-BulkDeleteAssociation](https://ap-northeast-1.console.aws.amazon.com/systems-manager/documents/AWS-BulkDeleteAssociation/content?region=ap-northeast-1) in the managed runbook.
The following is written in Python, but this is quite difficult without some programming skills. This is not smart, and for the purpose of this article, I want to show that it can be implemented by people with no programming knowledge, so I want to prove that we can do it without using services like AWS Lambda!
First of all, I will create a runbook with only the minimum required elements.
Select the "AWS APIs" tab under the search box and enter "modifynetwork" in the search box to find the ModifyNetworkInterfaceAttribute of the AWS API to be used this time. Drag and drop it to the middle of the "ModifyNetworkInterfaceAttribute" between Start and End.
{} Open the Code tab. You will see that "ModifyNetworkInterfaceAttribute" is being hit as an API, as shown below.
We want to put arguments here, as you can see from AWS Lambda code in the previous article,
As you can see from AWS Lambda code in the previous article, it seems to be sufficient to enter NetworkInterfaceId. [The API Reference is here](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_ModifyNetworkInterfaceAttribute.html) You can also see that you need to set AssociatePublicIpAddress to false in order to prevent the automatic assignment of Public IPv4 addresses.
Let's describe it as follows. The regular expression is written on the assumption that NetworkInterfaceId starts with "eni-" and that a combination of alphabets and numbers is entered. Also, entering (Required) in the parameter description will be treated as a required parameter. It is not mandatory to pass assumeRole as a parameter, but it is always recommended to do so. This is because you may want to use this runbook by assuming it from another AWS account. For example, there are use cases where a runbook is distributed to each account in CloudFormation StackSets, etc., and the runbook can be assumed and executed from an administrative account.
```
schemaVersion: '0.3'
description: Disable Public IPv4 on EC2.
assumeRole: '{{ AutomationAssumeRole }}'
parameters:
AutomationAssumeRole:
type: String
description: (Optional) The ARN of the role that allows Automation to perform the actions on your behalf.
default: ''
NetworkInterfaceId:
type: String
description: (Required) Network Interface Id
allowedPattern: ^eni-[a-z0-9]+$
mainSteps:
- name: ModifyNetworkInterfaceAttribute
action: aws:executeAwsApi
isEnd: true
inputs:
Service: ec2
Api: ModifyNetworkInterfaceAttribute
NetworkInterfaceId: '{{ NetworkInterfaceId }}'
AssociatePublicIpAddress: false
```
Now, enter a suitable name in NewRunbook and press "Create runbook".
## Test runs Automation runbook.
Open the runbook you have created. You can find the runbook you created in "Owned by me" tab.
Open it and click on Execute automation.
Before you do so, create an EC2 instance.
Check the network interface ID of the EC2 instance.
Try entering a Network Interface ID starting with "eni-" in "NetworkInterfaceId" field of the Input parameters and click Execute.
Check that the public IP address in the network interface ID on EC2 instance has been removed. You will see that it has been deleted. We will now see if this is really the end of the process.
## AWS Config settings
As before, I will use the "ec2-instance-no-public-ip" managed rule.
Open this Config rule and click on "Manage remediation"
Choose your own AWS Systems Manager Automation runbook.
Notice that only InstanceId can be passed as Resource ID parameter.
Oops, it seems that the network interface ID cannot be passed here, even though I really want to pass it here.
In other words, there seems to be no way to pass the network interface ID dynamically.
## Get a list of network interface ID from EC2 instance ID
We have no choice but to change course. You will find that you need to get the network interface ID from the EC2 instance in order to pass it on. There are two main methods. The first is to use DescribeInstances to get all the EC2 information and extract only the necessary information. The second is to use [DescribeNetworkInterfaces](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DescribeNetworkInterfaces.html) to get just network interfaces information.
This time, the information on EC2 instance will hardly be used, so we will hit DescribeNetworkInterfaces API to get the information on network interfaces only.
So, as shown below, DescribeNetworkInterfaces API is used to create the part that obtains information on network interfaces.
The code is as follows.
```
schemaVersion: '0.3'
description: Disable Public IPv4 on EC2.
assumeRole: '{{ AutomationAssumeRole }}'
parameters:
InstanceId:
type: String
description: The ID of the EC2 instance
AutomationAssumeRole:
type: String
description: (Optional) The ARN of the role that allows Automation to perform the actions on your behalf.
default: ''
mainSteps:
- name: DescribeNetworkInterfaces
action: aws:executeAwsApi
isEnd: true
inputs:
Service: ec2
Api: DescribeNetworkInterfaces
Filters:
- Name: attachment.instance-id
Values:
- '{{InstanceId}}'
outputs:
- Name: NetworkInterfaceIds
Selector: $.NetworkInterfaces..NetworkInterfaceId
Type: StringList
```
Network interface Ids can now be retrieved as a StringList.
There is a caveat here: if you look at the API specification for DescribeNetworkInterfaces, the Request Parameter is written as Filter.N, but at first, it was not clear how to write it in YAML.
The answer I arrived at is below, which is closer to the way [CLI](https://docs.aws.amazon.com/cli/latest/reference/ec2/describe-network-interfaces.html) is written.
```
Filters:
- Name: attachment.instance-id
Values:
- '{{InstanceId}}'
```
Another is Selector in outputs.
```
Selector: $.NetworkInterfaces..NetworkInterfaceId
```
This Selector allows you to specify which values are output and used in the next step. As an EC2 instance may have multiple network interface, it is necessary to retrieve them all, but when using Selector: $.NetworkInterfaces, only a MapList (like an associative array) can be specified for Type. In this case, the loop in the runbook cannot be used. Therefore, you need to get the array as a StringList, which can be done by writing "..". By writing this, the list of specified items can be retrieved as a StringList.
## Delete the public IPv4 address of the relevant network interface ID
Now that you have reached this point, the rest is easy. Create a runbook like the following.
The final code is as follows.
```
schemaVersion: '0.3'
description: Disable Public IPv4 on EC2.
assumeRole: '{{ AutomationAssumeRole }}'
parameters:
InstanceId:
type: String
description: The ID of the EC2 instance
AutomationAssumeRole:
type: String
description: (Optional) The ARN of the role that allows Automation to perform the actions on your behalf.
default: ''
mainSteps:
- name: DescribeNetworkInterfaces
action: aws:executeAwsApi
nextStep: Loop
isEnd: false
inputs:
Service: ec2
Api: DescribeNetworkInterfaces
Filters:
- Name: attachment.instance-id
Values:
- '{{InstanceId}}'
outputs:
- Name: NetworkInterfaceIds
Selector: $.NetworkInterfaces..NetworkInterfaceId
Type: StringList
- name: Loop
action: aws:loop
isEnd: true
inputs:
Iterators: '{{ DescribeNetworkInterfaces.NetworkInterfaceIds }}'
Steps:
- name: ModifyNetworkInterfaceAttribute
action: aws:executeAwsApi
isEnd: true
inputs:
Service: ec2
Api: ModifyNetworkInterfaceAttribute
NetworkInterfaceId: '{{ Loop.CurrentIteratorValue }}'
AssociatePublicIpAddress: false
```
"Create new version", then select "Create new default version" to create a new document.
Before you start testing, launch an EC2 instance and attach several Network Interfaces.
Then open the runbook, click on "Execute automation", enter the InstanceId and press Execute.
Check the previous screen to see if it has been disabled properly. If it is disabled as shown in the image below, you have succeeded.
## Conclusion
In this way, control can be exercised without programming knowledge. However, when you write it like this, you might think it's easy to do! And while that is the aim, there are some real quirks in the way YAML is written, and I had a lot of trouble with it.
At first, I thought that to get the network interface IDs as a list, I would need to write some Python code. And indeed, the first version of this blog did. While researching, I realized that it could be retrieved using "..".
I'm going to accumulate this kind of runbook writing style and work towards a situation where anyone can control the AWS environment!
Thank you for reading to the end.

https://github.com/Okerew/okrolearn
Why did I make this project? I made it as I saw problems with pytorch, there weren't any data analasys featurues, some more algortihms could be implemented, better support for sparse tensors with scipy, use of cupy, easier creation of cuda kernels. A view to simplify, use a lot more of python, create better support for cpus and MacOS.
Can be installed with `pip install okrolearn`

🎙️groCTO: Originals | Team Building 101: Communication & Innovation ft. Paul Lewis
In a recent episode, host Kovid Batra is joined by Paul Lewis, a seasoned technology leader with over 30 years of experience, shares his insights on building tech teams from scratch, offering valuable perspectives from his vast experience in the technology sector.
Paul addresses crucial elements by aligning developers to the basic principles of the organisation, implementing effective hiring and talent acquisition strategies, establishing robust processes and communication practices. At Pythian, he tackled challenges head-on, prioritised aligning tech innovation with business requirements, and offered parting advice for aspiring tech leaders on the importance of these elements in driving success.

“Of course, this mission and vision must be interesting to your people. If it’s not interesting nobody will follow.” — Adrian Stanek
🤝 Aligning Developers: A Personal Approach
Adrian Stanek whom you might know as snackableCTO for his short insights shares his playbook on how to bring a team together to foster a sense of comradeship and shared purpose.
Imagine you have a clear action and go present it to your team. 10 people fill the room and you enthusiastically go through your presentation and boom, resistance. Apparently for no reason. Why is this? Let’s dive in!
Step 1: Vision
Clearly communicate the mission and vision to inspire your team. This doesn’t mean you tell your team what to do. Merely stating what the desired outcomes are and reasons for picking them.
The Mission and Vision are about effective storytelling to inspire your people. It’s not to paint a pretty picture where everyone is happy.
“There is no way to make everybody happy. We need to go through something.”
It’s to give your engineering team something to believe in. Make your developers the story's heroes; they will follow the journey through.
Finding it difficult to align your business & dev efforts or unsure about clear goals, great communication, or strategic alignment? At groCTO connect, our mentors are here to help you navigate your leadership career with confidence.

Advance your leadership skills with 1:1 mentorship from top CTOs, VPEs & tech leaders.
Step 2: Overcome Resistance
Adrian highlights a key aspect of resistance. Don’t suppress it, use it as a form of feedback, albeit clumsy.
Resistance tells us:
I like XYZ language better
ABC is more effective than XYZ because of…
I just mastered XYZ, so why should I start learning something new?
I don’t want to start at the beginning again; I would instead join another team to stay with what I have learned.
Disagreements will naturally arise even in high-performing teams. Focus on showing to your team what they have to gain by overcoming the resistance rather than shirking it.
Resistance is not permanent, it is friction to the initial momentum. Once the team is moving steadily in the same direction resistance diminishes.
This is key for the next step…
Step 3: Ownership & Responsibility
Everyone has a bit of a micromanager inside of us. Define the desired qualities and frameworks you expect from your teams and let them figure out the details. Remove obstacles but do not force your own preferred path onto the team. This will encourage them to regress back to resistance and vision-building.
The specifics of achieving that mission should be left to the team. A cohesive, motivated team is grown by tackling challenges together where they are free to explore their proposed solutions within given constraints.

One of the most frequent questions Gartner gets asked is how to go from zero to one. Engineers and leaders from 20 large tech companies were interviewed, including DoorDash, Lattice, and Yelp.
Hopefully after reading through the main findings you’ll more easily decide whether it is time for such an initiative in your company—or how to improve an existing one.
30% of companies start with CI/CD pipelines…
… followed by CI/CD pipeline bottlenecks as the company grows
Delivery bottlenecks are highly visible and become the focus for investment
Investments used for pipeline optimisations and engineering intelligence
Other successful alternative reasons to starting DevProd initiatives include:

🙈 The 10 Most Common Mistakes of First-Time CTOs, #5 and #6
The Chief Technology Officer position is a rare breed. It is a mix of entrepreneurial gusto and technical ability. Always trained in the field and through experience, usually with unrelated fields of academic study. Most CTOs have grown into the role by necessity or picked it as founders.
Sergio Visinoni has a practical series for patterns he observed by first-time CTO to help them avoid obvious, yet unintuitive mistakes. This brief is about the ones he numbered number #5 and #6.
#5 100% in Reactive mode
Reduce the chaos surrounding your calendar by building a healthy planning discipline. According to Sergio, the non-negotiable are:
Address the systemic issues causing all the fires
Dedicate a non-trivial amount of time and attention to proactive work
Set a time budget for recurring weekly meetings
#6 Tech Roadmap Separate from the Product Roadmap
All the important problems are on the product roadmap. That’s also where the most difficult conversations lay in wait, in contrast to the relative comfort of technology issues, maintenance and keeping the lights on activities.
“When building a tech roadmap in isolation, you're essentially pushing down all the unsolved prioritiSation issues to the team.”
Sergio advices CTOs stuck on this treadmill to approach the product priorities first. Validate them with the appropriate stakeholders and leverage commitments as a vessel to build trust. This trust is then available when technology concerns get translated to business outcomes and make their way onto the list.
That’s for Today!
Whether you're hustling with your side projects, catching up with the latest technologies, or simply relaxing & recharging, wish you all a lovely day ahead.

1,917,503 | Port your Supabase App to Hyperlambda | Most of our partners don't care about anything but our ability to deliver kick ass AI chatbots.... | 0 | 2024-07-09T15:00:16 | https://ainiro.io/blog/port-your-supabase-app-to-hyperlambda | lowcode, productivity | Most of our partners don't care about anything but our ability to deliver [kick ass AI chatbots](https://ainiro.io/ai-chatbot). However, [Magic Cloud](https://ainiro.io/magic-cloud) is actually a complete low-code and no-code software development automation platform - And some of our partners require more than just an AI chatbot, such as complex integrations with their existing systems - At which point Hyperlambda and our low-code and no-code features becomes interesting.
In addition, there are according to Supabase themselves roughly 1 million people having a PostgreSQL database hosted by Supabase, without the ability to use it for anything intelligently what so ever, without using _"edge functions"_ - Which of course completely eliminates all low-code features, while also ensuring you end up with with something that can only be described as Spaghetti.
In this article I will therefore explain the details about the first touch point in Magic, specifically the URL resolver, and help you understand why Magic is a solution to your Supabase scalability and code quality problems.
## One Endpoint to Rule them All
Magic actually has only one single endpoint. It's written in C#, and here's roughly how it looks like.
```csharp
namespace magic.endpoint.controller
{
public class EndpointController : ControllerBase
{
[HttpGet]
[HttpPut]
[HttpPost]
[HttpPatch]
[HttpDelete]
[Route("{*url}")]
[RequestFormLimits(ValueLengthLimit = int.MaxValue, MultipartBodyLengthLimit = int.MaxValue)]
public async Task<IActionResult> Execute(string url)
{
return await HandleRequest(Request.Method?.ToLowerInvariant(), url);
}
}
}
```
Ignoring the fact that C# on .Net Core 8 is _"a bajillion"_ times faster, more scalable, and less resource demanding than Python, PHP, and NodeJS - Let's try to look at how the above code actually does what Magic allows for it to do.
The above wildcard character ensures that the above method is invoked for _every single HTTP request towards the server_, for all 5 most commonly used verbs. This allows us to use the path of the URL as a _"parameter"_, which results in loading up a [Hyperlambda](https://docs.ainiro.io/hyperlambda/) file matching the specified URL, parse this file into a lambda object - Which then is executed and returns some result to the client.
## Internals
I'm not going to give you all the gory details of how it was implemented, but the above `HandleRequest` invokes a dependency injected service according to the following logic.
```csharp
services.AddScoped<IHttpExecutorAsync>(provider => {
var context = provider.GetRequiredService<IHttpContextAccessor>().HttpContext;
if (context.Request.Path.StartsWithSegments("/magic"))
return provider.GetRequiredService<HttpApiExecutorAsync>();
return provider.GetRequiredService<HttpFileExecutorAsync>();
});
```
Basically, it's got two service implementations; One service for API requests and another service for file requests. API requests requires the URL to start out with _"/magic/"_, while everything else is handled by the default file server.
### The File Server
The default file server is a Hyperlambda web server, allowing us to serve static content such as HTML, CSS, and JavaScript - While also applying _"server-side mixin logic"_ to HTML files. Mixin logic is Hyperlambda code dynamically substituting parts of the HTML with the result of executing Hyperlambda code.
The latter allows us to have Hyperlambda _"code behind files"_ that are executed when some URL is requested.
The file server service appends _".html"_ by default on requests without an extension, prepends _"/etc/www/"_ to the path, and then simply returns whatever it finds at this specific location, trying to serve it as the correct MIME type, and also applying HTTP headers in the process. To understand the beauty and flexibility of this approach, realise our website was entirely created as a Hyperlambda website.
Not only did we build our own CMS based upon GitHub, GitHub Workflow Actions, publishing blogs as Markdown dynamically parsed by the backend as they're being served - But we even built our own programming language and web server to serve the frikkin' thing.
> But please, don't tell your senior dev, he'll think I'm crazy ... 😂
Below you can literally see with your own eyes how even our website is in fact a cloudlet by itself, allowing you to use the cloudlet to serve your own websites, including sites built on ReactJS, Angular, or VueJS. So not only is Magic a low-code and no-code software development alternative to your existing software development platform - But it's also in theory a replacement of WordPress and Joomla if you wish.
This allows me to write blogs using Visual Studio Code, push towards GitHub, and have a workflow action triggered that moves the updated code into our website, which is simply a Magic Cloudlet being resolved from ainiro.io.
Once the code makes it to our ainiro.io cloudlet, it will dynamically execute any associated Hyperlambda code behind files as some URL is being requested.
Since Magic Cloud therefore by the very definition of the term is a _"web server"_, we can also (duh!) serve other types of web apps, such as React, Angular, static HTML, etc.
This is how we deploy the AI expert system in fact, which is just an Angular app, built during push towards GitHub, zipped, transferred to our internal _"AppStore"_, and served through plugins in your cloudlet. Every time I push towards the master branch in GitHub, a new _"version"_ of the AI Expert System is automatically built and uploaded to our _"AppStore"_.
### The API server
The API service is a bit different. First of all, it'll only kick in on requests that starts out with _"/magic/"_. Then it will only resolve URLs going towards either your _"/system/"_ folder or your _"/modules/"_ folder. This allows you to have private files that you don't publicly expose to the web directly, without having some piece of Hyperlambda code explicitly returning the file of course.
Basically, unless your file is in one of these 3 folders, it's not even possible in theory to access it from the outside of your cloudlet.
* /etc/www/
* /modules/
* /system/
The first thing the service does is to remove the _"/magic"_ parts, for then to append the verb in small case, and finally end the request with _".hl"_. So an HTTP GET request resembling the following _"/magic/modules/foo/bar"_ will end up being resolved by a Hyperlambda file at the path _"/modules/foo/bar.get.hl"_.
This is often referred to as _"programming by convention"_ since there's no need for any configuration object to declare which files are served by which URL. Need a new endpoint? Chose a verb and create a new Hyperlambda file, and you're done!
The Hyperlambda is parsed and executed, after having parameters passed into it - For then to return the result of the execution to the client. Since Hyperlambda is a Turing complete environment, this allows you to do literally anything you wish within this Hyperlambda file, and have the result of the execution returned to the client.
At least in theory this allows you to do _anything_ you want inside of this Hyperlambda file, including reading from your database, invoking 3rd party services, or accessing the file system to read and write files. Below is a Hyperlambda file for reference purposes.
And yes, the system is *scattered* with AI features, such as using AI to automatically generate documentation for files, in its help system, and even an integrated code support AI chatbot that will to some extent even *generate code* for you!
Since only files with an HTTP verb as the second last parts of their path are possibly to resolve, this allows you to _"hide"_ internals of your application that's not possible to resolve using the API web server.
And if you're missing something in Hyperlambda, adding C# code and interacting with it from your existing endpoint is literally as easy as creating a new C# class as follows.
```csharp
[Slot(Name = "foo.bar")]
public class FooBar : ISlot
{
public void Signal(ISignaler signaler, Node input)
{
input.Value = 42;
}
}
```
The above C# class will once your cloudlet is initialised allow you to invoke a slot named __[foo.bar]__ that simply returns the value 42.
This feature of Hyperlambda allows you to create C# code, and _"mix it in"_ with your low-code software development automation parts, resulting in that it literally becomes **impossible to get stuck with something you cannot do**!
> If Supabase is a steam locomotive, then Hyperlambda is an inter-galactical spaceship with warp drive from the future!
The process to port your existing Supabase solutions is as follows.
1. Take your existing Supabase PostgreSQL database and point Magic towards it
2. Click a button and you're now done with 80% of your job
3. Solve 99% of the rest of the problem with Hyperlambda, typically using declarative programming constructs, not even requiring you _understand_ Hyperlambda
4. Solve the remaining parts with C# and integrate with Hyperlambda
Porting _any_ Supabase database towards the above is typically a 5 minute to 10 hour job, at which point you'd end up with something 1,000x faster and 1,000,000 times more scalable, and 1,000,000,000 more flexible!
## Wrapping Up
Magic Cloud is a web server, similarly to [PostgREST](https://postgrest.org/en/v12/). The difference is that PostgREST doesn't generate code files, it only parses QUERY parameters and JSON payloads, and uses these as its foundation to interact with your database, dynamically building SQL in the process.
Hyperlambda is also a web server, but a web server that allows you to add _code_ to your endpoints. Most of this code is **automatically generated by the machine**, which explains our slogan being _"Where the Machine Creates the Code"_. However, the ability to dynamically add business logic to your database endpoints is what makes Magic a _real_ low-code framework, while Supabase is a _toy_ low-code framework. Below you can see the difference for yourself.
This allows you to _"intercept"_ database access in your cloudlet with business logic, allowing Magic to do _"a bajillion"_ things that PostgREST and Supabase can simply never do.
So now you understand why it is that once you're stuck with your Supabase solution, and you need help, we at AINIRO can help you and _"port"_ your existing backend solution to Magic in a couple of hours, and add whatever amounts of business logic you want to on top of your database CRUD endpoints.
The funny thing is that you can still _keep_ your PostgreSQL database hosted by Supabase, using your Magic cloudlet as an intermediary and API _"gateway"_ to your database, resulting in zero down time during the porting phase. And when you're done, you simply swap out a simple CNAME DNS record, and you've painlessly upgraded to a modern low-code web application solution.
Have a najs day 😊

At CardMakerz.com, we specialize in helping you craft personalized greeting cards that stand out. In this post, we’ll share some tips and tools to help you design the perfect card for any occasion.
**Why Personalized Greeting Cards Matter**
In an age of digital communication, a physical greeting card feels even more special. It shows that you took the time to think about the recipient and put in the effort to create something unique. Personalized cards can:
1. **Strengthen Relationships**: A thoughtful card can show friends and family that you care.
2. **Express Your Creativity**: Designing your own cards allows you to express your artistic side.
3. **Make Memorable Keepsakes**: Custom cards are often kept as cherished mementos.
**Tips for Designing Custom Greeting Cards**
1. **Know Your Audience**
- Consider the recipient’s interests and personality. Are they into nature, modern art, or vintage designs? Tailor your card to their tastes.
2. **Choose the Right Theme**
- Select a theme that suits the occasion. For example, use bright colors and playful fonts for a birthday card, or elegant and subtle designs for a wedding invitation.
3. **Use High-Quality Images**
- Whether you’re using personal photos or stock images, ensure they are high resolution. Blurry or pixelated images can detract from the overall look of your card.
4. **Incorporate Personal Touches**

However, as developers, we've all faced the daunting challenge of "callback hell" or the "pyramid of doom." This phenomenon occurs when nested callbacks become deeply nested, making code difficult to read, maintain, and debug.
## What is Callback Hell?
Callback hell refers to the situation where multiple nested callbacks are used to handle asynchronous operations. While callbacks are a fundamental part of JavaScript, overusing them can lead to a tangled, pyramid-like structure of code. This not only makes the codebase look messy but also complicates error handling and logic flow.
## Example of Callback Hell
Let's take a look at a simple example:
```
const fs = require('fs');
fs.readFile('file1.txt', 'utf8', (err, data1) => {
if (err) {
console.error('Error reading file1:', err);
return;
}
fs.readFile('file2.txt', 'utf8', (err, data2) => {
if (err) {
console.error('Error reading file2:', err);
return;
}
fs.readFile('file3.txt', 'utf8', (err, data3) => {
if (err) {
console.error('Error reading file3:', err);
return;
}
console.log('Files content:', data1, data2, data3);
});
});
});
```
In this example, each fs.readFile call is nested within the previous one, creating a pyramid structure that is difficult to follow and maintain. As the number of callbacks increases, the complexity and indentation levels grow, leading to unreadable code.
## Why Callback Hell is Problematic
### 1. Readability:
Deeply nested callbacks make the code hard to read and understand. The logic flow is not linear, and it's easy to get lost in the maze of functions.
### 2. Maintainability:
Updating or modifying deeply nested callback structures is challenging. Adding new functionality or changing existing logic can introduce bugs and errors.
### 3. Error Handling:
Managing errors in callback hell is cumbersome. Each callback needs its own error handling, leading to duplicated and scattered error management code
### 4. Debugging
Debugging deeply nested code is time-consuming and frustrating. Tracing the source of an issue through multiple layers of callbacks can be difficult.
## Escaping Callback Hell
Thankfully, modern JavaScript provides several tools and patterns to avoid callback hell and write cleaner, more maintainable asynchronous code.
### 1. Promises
```
const fs = require('fs').promises;
fs.readFile('file1.txt', 'utf8')
.then(data1 => fs.readFile('file2.txt', 'utf8'))
.then(data2 => fs.readFile('file3.txt', 'utf8'))
.then(data3 => console.log('Files content:', data1, data2, data3))
.catch(err => console.error('Error reading files:', err));
```
### 2. Async/Await
Async/await is built on top of promises and provides a more synchronous-looking syntax for asynchronous code.
```
const fs = require('fs').promises;
async function readFiles() {
try {
const data1 = await fs.readFile('file1.txt', 'utf8');
const data2 = await fs.readFile('file2.txt', 'utf8');
const data3 = await fs.readFile('file3.txt', 'utf8');
console.log('Files content:', data1, data2, data3);
} catch (err) {
console.error('Error reading files:', err);
}
}
readFiles();
```
### 3. Modularization
Breaking down code into smaller, reusable functions can help manage complexity and improve readability.
```
const fs = require('fs').promises;
async function readFileContent(filePath) {
return await fs.readFile(filePath, 'utf8');
}
async function readFiles() {
try {
const data1 = await readFileContent('file1.txt');
const data2 = await readFileContent('file2.txt');
const data3 = await readFileContent('file3.txt');
console.log('Files content:', data1, data2, data3);
} catch (err) {
console.error('Error reading files:', err);
}
}
readFiles();
```
## Conclusion
Callback hell is a common challenge in JavaScript development, but it's one that can be overcome with the right techniques. By leveraging promises, async/await, and modularization, we can write cleaner, more maintainable asynchronous code. As developers, it's crucial to adopt these modern practices to improve the quality and readability of our codebases.
Let's embrace these tools and move away from the dreaded pyramid of doom, creating code that is not only functional but also elegant and easy to manage.
