Before going to prepare or clear any certification exam we must know why it is relevant and what importance it holds.

So when you are working for an organization or looking for a change. To get interview call, you need something alongside your resume to maximize your chances and even clients want to bet on your skills if you are certified. Hence to standout you need an X factor but that does not mean, not much knowledge is required or hands-on. Remember knowledge is power.

Now lets go deep and find how to successfully climb a ladder of  certification exam.

Stage 1 : Choose the right certification, based on your interest and pre skills or things you are actively working and need a industry validation.

Stage 2 : Know the exam in & out. What are the skills tested with its weightage so that you can make a roadmap to start preparing.

Stage 3 : Start slow with theory and later gradually go for practice and hands-on. In industry you work on system, use keyboard and its never oral.

Stage 4 : Go for the practice exam and observer your weak areas to brush them up and go through again if in doubt.

Stage 5 : Finally have confidence, patience and sit for the exam. Note there are no fixed seats or openings, you perform well you won.

Cheers! Please add or recommend more if I missed something.
Need help with my Midjourney prompt generator
Tags: midjourney, html, ai, css
Published: 2023-06-20 03:04:39

Hello! I'm quite new to coding and have just begun learning HTML. I've developed a prompt generator for Midjourney. I want to enhance it now by adding a feature allowing users to input a specific "keyword." And based on the keyword entered, the system will generate a related prompt. So my question is, what type of code would allow the user to enter the keyword and provide the prompts based on it?

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/uxnti9qpz866y9ng8mj4.png)

This is my current [live version](https://thecognitivequest.com/midjourney-prompt-generator-the-only-free-tool-you-need/) of Midjourney prompt generator

Published: 2023-06-20 02:55:17

To generate an HTML Allure report in the Cypress framework, you can follow these steps:

**Install the Allure Command Line tool:**

The Allure Command Line tool is required to generate the HTML report. Install it globally using the following command:

```
npm install -g allure-commandline
```

**Add the Cypress Allure Plugin:**

Install the Cypress Allure Plugin by running the following command:

```
npm install --save-dev @shelex/cypress-allure-plugin
```

**Configure the Cypress plugin:**

Open the cypress/plugins/index.js file and add the following code:

```
const allureWriter = require('@shelex/cypress-allure-plugin/writer');

module.exports = (on, config) => {
  allureWriter(on, config);
  return config;
};

```

**Run your Cypress tests:**

Run your Cypress tests using the Cypress command:

```
npx cypress run
```

**Generate the Allure report:**

After running the tests, the Allure report data will be stored in the allure-results directory.

To generate the HTML report, use the following command:

```
allure generate allure-results --clean && allure open
```

This command will generate the HTML report based on the data in the allure-results directory and open it in your default browser.

That's it! You have generated an HTML Allure report for your Cypress tests. The report will provide detailed information about the test execution, including test cases, steps, attachments, and more.

Webhook vs Socketio
Tags: webhook, socketio
Published: 2023-06-20 02:04:32


Webhooks and WebSockets are both web technologies that allow for real-time communication between applications. However, they have different strengths and weaknesses, and are best suited for different use cases.

Webhooks are one-way connections that allow an application to send data to another application. When an event occurs in the first application, a webhook is triggered and sends data to the second application. Webhooks are typically used for event-driven communication, such as when a user signs up for a newsletter or makes a purchase.

WebSockets are two-way connections that allow applications to communicate with each other in real time. WebSockets are typically used for applications that require constant communication, such as chat applications or multiplayer games.

Here is a table summarizing the key differences between webhooks and WebSockets:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/qutntiac3p68wfsx2mn7.jpg)

When to use webhooks:

- When you need to send data from one application to another in a one-way fashion.
- When you need to ensure that the data is delivered reliably.
- When you need to scale the communication easily.

When to use WebSockets:

- When you need to communicate with another application in real time.
- When you need to send a lot of data between applications.
- When you need to ensure that the communication is secure.
- In general, webhooks are a good choice for applications that need to send data from one application to another in a reliable and scalable way.

WebSockets are a good choice for applications that need to communicate with another application in real time and send a lot of data.

Here are some examples of applications that use webhooks:

- Email marketing applications: When a user signs up for an email list, the email marketing application can send a webhook to a CRM application to create a new contact record.
- Payment processing applications: When a user makes a purchase, the payment processing application can send a webhook to an inventory management application to update the product stock levels.
- Chat applications: When a user sends a message in a chat application, the chat application can send a webhook to a notification service to send a notification to the recipient.

Here are some examples of applications that use WebSockets:

- Chat applications: Chat applications use WebSockets to allow users to communicate with each other in real time.
- Multiplayer games: Multiplayer games use WebSockets to allow players to interact with each other in real time.
- Stock trading applications: Stock trading applications use WebSockets to get real-time updates on stock prices.
Set up React on Mac
Published: 2023-06-20 00:40:04

## Install Node.js

Check `brew` version.
```console
$ brew -v
Homebrew 4.0.23
```

## Install nodebrew
Following this post, I decided to install nodebrew. I won't be an active frontend developer, but this might help in the future to switch or maintain versions of `npm` as described.
https://fromscratch-y.work/en/blog/programming/mac-nodejs-install/#sec4-1

```console
$ brew install nodebrew
(...snip...)
==> Caveats
You need to manually run setup_dirs to create directories required by nodebrew:
  /opt/homebrew/opt/nodebrew/bin/nodebrew setup_dirs

Add path:
  export PATH=$HOME/.nodebrew/current/bin:$PATH

To use Homebrew's directories rather than ~/.nodebrew add to your profile:
  export NODEBREW_ROOT=/opt/homebrew/var/nodebrew

zsh completions have been installed to:
  /opt/homebrew/share/zsh/site-functions
==> Summary
🍺  /opt/homebrew/Cellar/nodebrew/1.2.0: 8 files, 40.6KB

(...snip...)
```

Not sure what the `setup_dirs` does...

Added the PATH to my `.zshrc`
```console
$ echo 'export PATH=$HOME/.nodebrew/current/bin:$PATH' >> ~/.zshrc 
$ source ~/.zshrc 
```

## Specify the node version
```console
$ nodebrew ls-remote
v0.0.1    v0.0.2    v0.0.3    v0.0.4    v0.0.5    v0.0.6    

v0.1.0    v0.1.1    v0.1.2    v0.1.3    v0.1.4    v0.1.5    v0.1.6    v0.1.7
(...snip...)

v20.0.0   v20.1.0   v20.2.0   v20.3.0   
(...snip...)

io@v3.0.0 io@v3.1.0 io@v3.2.0 io@v3.3.0 io@v3.3.1 
```

Install the stable version
```console
$ nodebrew install stable
$ nodebrew list
v20.3.0
```

Activate the installed version
```console
$ nodebrew use v20.3.0
use v20.3.0
$ node -v
v20.3.0
$ npm -v
9.6.7
```

## Create an app
```console
$ npx create-react-app react-app
```
According to this page https://react.dev/learn/start-a-new-react-project, that creates [Next.js](https://nextjs.org) project.

To run, go down to the created project folder, and start `npm`.
```console
$ cd react-app
$ npm start
```

This automatically opens `http://localhost:3000` with your default browser and show the starter page.

![React Starter Page](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/wtnltxfs22psabdz0zvs.png)

Further more, below comment will create a `build` folder for deployment.
```console
$  npm run build
```
Source: https://create-react-app.dev/docs/deployment/ 

My plan it to run a server using Spring Boot.


## Why React?
As a Java backend developer, I need to work with frontend developers. Also wanted to set up a simple website based on Java backend, and picked React as the FE framework - simply because it's most trending framework on the FE side.

While bugs really move and infect plants, skin, and code .. they have much of a role in our lives that should make us take them seriously, … I mean differently! 😅

Of all sorts of bugs 🐞 the one in the code could really make you lose a lot of money 🤣 and you can not kill them by using pesticides, but rather by having a peaceful-mind that never runs outta patience, digging deep and reviewing the  codebase that you earlier celebrated its release … what the bug!

With AI, we reached the point where we are, now, developing AI that is capable of killing real bugs:

> "AI-controlled robotic laser can target and kill cockroaches" - newscientist.com

If you ask me, I couldn't let this get past my imagination 👉 This is StarWars In The Field lol 😂
but how about a bug in the AI? 
could we have a robot w/ laser? but it has a bug in their codebase … re-appearing in the news headlines again but this time it reads:

> "Uncontrolled AI robot chasing framers with a green laser beam" - thatisinmymind.me

but wait? what about the poor farmers.. and how could they self-defend themselves against the out-of-control robot?

for that we should continue with what the news could read:

> "…and while farmers are making their way out of the field, they keep releasing more bugs to distract the raged robot." 😂

That's a fair fight, bugs vs bugs and we live in the margin.

But seriously, if we could ever take anything seriously in this publication 😆 .. why we do not enjoy bugs?

We all know a bug could be the feature u r about to discover, it could be your app's competitive edge, or it could be your best selling point.

Is it just because they r not intended? Or just cuz they feel off?

* Cuz I know as everybody knows that not all bugs r hated, like..

- ..imagine a switch button that toggles on/off but it fills the whole width of your screen so the switcher travels onChange from edge to edge .. wouldn't that be playful and inviting for more session duration avgs and lesser bounce rates .. pllllllllllz 🙃

* How about a website that is built w/ unintentional components, full of bugs.. 

 -  ..man, I'd stay there, forever, adventuring for 👉 from where the sidebar could show and come in for me 😂😂

* Wait! ✋

 -  …how about an app for developers that rewards (The Best Generated Bug) and we r battling 🙃🤣🤣


That's enough for today 😁

Muy posiblemente antes el tener Linux dentro de tu computadora te hacia ver como una persona que sabía lo que hacías porque desde la instalación no era meramente a base de clics, sino que debías de tener un entendimiento de lo que estabas a punto de hacer en cuanto a las particiones que tanto ibas a destinar a cada una y la razón detrás de ello. No solo eso sino que también necesitabas un ambiente lo más parecido a tu ambiente de QA y Production para evitar errores de compatibilidad.

Pero con el paso del tiempo esto ha cambiando drásticamente para la parte de desarrollo de software ya que con la llegada de la tecnología de contenedores como es Docker. Elegir tu sistema operativo en este momento tiene mas que ver con tus gustos y en donde te sientes mas cómodo mas que con la compatibilidad entre sistemas operativos.

Antes Windows de Microsoft era una plataforma que no estaba diseñada para la parte de desarrollo porque tenia muchos problemas y realmente muchas de las herramientas no estaban hechas para esta plataforma. Pero el gigante tecnológico se a empeñado fuertemente en revertir esto. Algunas de sus principales jugadas que hay que tener en cuenta es la creación de Windows Subsystem Linux (WSL) y Visual Studio Code (VS code), este último se comió el mercado de los editores de texto y con la cantidad de plugins que puedes añadir no tiene nada que envidiarle a un IDE.

GitHub fue comprada en 2018 y ello permitió que junto con su colaboración con OpenAI generaron Copilot una IA que te ayuda a autocompletar tu código y hace sugerencias de acuerdo a lo que estas haciendo.

En el Microsoft Build de 2023 mostraron que habrá un dashboard especialmente diseñado para desarrolladores en donde verás las cosas las relevantes acerca de tus proyecto y demás. No solo eso sino que también podrás configurar una partición especial para tus proyectos en donde tendrás una mejora en el rendimiento y otras cosas.

Sinceramente yo como desarrollador; Microsoft me ha hecho la vida mas sencilla para que me dedique a lo que verdaderamente importa: programar. Tiene años que no ocupo una distribución de Linux como mi sistema operativo principal pero no lo hecho de menos ahora con todas las posibilidades que existen dentro de Microsoft y su ecosistema que esta construyendo para desarrolladores.

Claramente mi yo de la universidad hubiera repudiado y hecho feo a Windows pero las cosas han cambiado y es de sabios cambiar de opinion.
