Vanilla Flask vs. RESTful Flask
Published: 2023-08-29 04:06:14

Flask is a popular framework in Python that developers use to build applications and APIs. There are two different ways to go about it- you can use either "Vanilla Flask" or "RESTful Flask" (it could also be called Flask-RESTful).

Vanilla Flask
Vanilla Flask is the traditional way of building APIs, where you manually define the routes, handle HTTP methods, and manage data. While the setup is slightly more involved, it has the added benefit of being more flexible.

If you wanted to create an API to manage a list of books using Vanilla Flask it could potentially look like this-
```
from flask import Flask, jsonify

app = Flask(__name__)

books = [
    {"id": 1, "title": "Harry Potter", "author": "J.K. Rowling"},
    {"id": 2, "title": "The Hobbit", "author": "J.R.R. Tolkien"}
]

@app.route('/api/books', methods=['GET'])
def get_books():
    return jsonify(books)

if __name__ == '__main__':
    app.run(debug=True)
```

RESTful Flask
RESTful Flask, which is sometimes referred to as Flask-RESTful, is an extension of Flask that has a more structured way of building APIs. It uses concepts like resources and HTTP methods as class methods, which simplify the process of creating APIs.

And if you wanted to create an API to manage a list of books using RESTful Flask it could potentially look like this-
```
from flask import Flask
from flask_restful import Api, Resource

app = Flask(__name__)
api = Api(app)

books = [
    {"id": 1, "title": "Harry Potter", "author": "J.K. Rowling"},
    {"id": 2, "title": "The Hobbit", "author": "J.R.R. Tolkien"}
]

class BookList(Resource):
    def get(self):
        return books

api.add_resource(BookList, '/api/books')

if __name__ == '__main__':
    app.run(debug=True)
```
Managing Docker Contexts to Prevent Image Disappearance and Permission Issues
Published: 2023-08-29 03:36:22

Introduction

In the world of containerisation, Docker has become an integral tool for developers to manage and deploy applications seamlessly. However, occasional hiccups in the Docker environment can lead to perplexing issues, such as vanishing local Docker images and unexpected permission requirements. In this article, we'll delve into a recent experience that sheds light on this phenomenon and explore the solutions to mitigate such occurrences.

The Mysterious Disappearance

Imagine a scenario where you've just installed Docker Desktop, and suddenly, your locally built Docker images have vanished into thin air. Additionally, executing basic Docker commands prompts an unexpected request for sudo privileges. Without elevated permissions, an error message resembling the following surfaces:

> "Cannot connect to the Docker daemon at unix:///home/xyz/.docker/desktop/docker.sock. Is the Docker daemon running?"

Perplexing as this may seem, the root cause of this anomaly lies in Docker's inherent architecture and its management of different contexts.

Docker Context: Unveiling the Culprit

Docker Desktop, upon initiation, crafts a dedicated context to serve as a target for the Docker Command-Line Interface (CLI). This context is set as the active one for the CLI's use. This seemingly innocuous process serves a vital purpose: it prevents conflicts with a local Docker Engine that could potentially be operational on the Linux host and utilizing the default context.

The purpose of this context isolation becomes apparent during shutdown. When Docker Desktop closes, it restores the previously employed context to ensure a smooth transition between different Docker environments.

Solving the Mystery: Unveiling the Solution

Now that we've dissected the cause, let's unravel the solution. The Docker website itself offers insights into this quandary, suggesting a course of action to restore normalcy. If you find yourself grappling with Docker images mysteriously disappearing and unexpected permission requirements, consider these steps:

One initial remedy is to add yourself to the 'docker' group using the following command:

1. User Group Addition:
```py
sudo usermod -aG docker $USER
```

2. Context Exploration:

To comprehend the current context at play, utilize the command:

```
docker context list
```
3. Context Switching:

When you are not using docker desktop if you suspect that Docker Desktop might have altered your context, manually switch back to your original context using:

```
docker context use <context-name>
```
Exploring WebdriverIO
Tags: testing, testdev, automation, node
Published: 2023-08-29 02:45:45

Hello QA's, 
 
I recently bumped into WebdriverIO during my search for a better UI automation tool. Being into Selenium+Java, I have always found it to be hectic building frameworks, implementing listeners / hooks and wrappers, writing custom reporters / loggers and what not. But this new NodeJS based tool ( in fact, almost all the new age tools including Cypress and Playwright ) has made things simpler; be it the setup or integration with third party tools. I wanted to share with you what I found catchy with this particular tool. The points below might be applicable to others as well but for now let's focus on WebdriverIO. 

- **Setup** - All you need to have as pre requisite is a node installation and an IDE. The npm will do the rest for you.
- **Configuration** - The whole bulky framework is now reduced to a single **config.js** file. You just command the WebdriverIO "Hey! Run the tests with chrome." Or "I want you to generate an allure report for my test". And that's it. WebdriverIO does it for you.
The reporters, logging, hooks, drivers, test framework; all these are mentioned in the conf.js file.  
- **Integrate any kind of tests you wish to**; be it Web UI or Mobile App UI or even API/ webservices  calls. This is one of the features which made me pick WebdriverIO. I work on projects that has test scenarios integrated with Web + Mobile App + REST API. And most of the UI automation tools out there doesn't have this capability of integrating mobile app testing. WebdriverIO lets you achieve this by integrating Appium to your test suite. 
- **Run your tests anywhere** without touching your code. WebdriverIO executes your tests in local env as well as any cloud platforms ( saucelabs, browserstack etc. ). You just mention it in your config.js and leave the rest to WebdriverIO. 
- **Multiremote** - a feature that helps you handle multiple browser / driver sessions within the same worker. You can use this for cross browser testing, a server client app testing or a web + mobile app integrated testing. 
- **Multiple test frameworks support** - mocha, jasmine and cucumber. I was able to maintain two different test suites within the same project - cucumber based suite for e2e tests and mocha based suite for data driven tests.
- Features like **Isolated test contexts**, **auto-waiting**, **own assertion library**, **component testing**. 
- And a detailed **documentation**. 
 
 
But still I feel few things are missing in WebdriverIO which would have made my life easier. 
 
- Better debug options 
- Better ways to handle flaky tests 
- A code generator for recording the tests 
 
Here is one sample project I have done. The WebdriverIO team was kind enough to list this among their boilerplate projects.

VSCode + SvelteKit 에서 느려질 때
Tags: svelteautoimport
Published: 2023-08-29 02:10:03

SvelteKit 프로젝트가 조금 더 커지가 새로운 폴더나 파일을 만들 때 한 번도 본 적 없는 프로그래스가 뜰 때가 있다. 그러면서 Prettier가 파일을 읽는 중이라는 팝업이 뜨기 때문에 처음에는 `prettier too slow` 같은 식으로 검색을 해봤지만, 딱히 나오는 것이 없었다. 

그래서 svelte와 관련된 확장들을 하나씩 꺼봤는데, 범인은 `Svelte Auto Import` 였다. https://marketplace.visualstudio.com/items?itemName=pivaszbs.svelte-autoimport

하루에도 몇 번씩 저런 증상이 있던게 이걸 사용 중지하고나서는 이틀 째 전혀 느려지는 증상이 없다.
OpenAI finally launches ChatGPT Enterprise
Published: 2023-08-29 01:47:06

OpenAI has announced a new product for businesses that want to use its AI technology. ChatGPT Enterprise is a subscription service that offers unlimited, fast, and secure access to GPT-4 and other features that can help businesses improve their workflows and communication.

If you want to stay ahead of the curve in AI and tech, [look here first.](https://supercharged-ai.beehiiv.com/subscribe?utm_source=dev-to&utm_medium=chatgpt-enterprise&utm_campaign=campaign)

**Why this matters:**

- **ChatGPT Enterprise is the first product that lets businesses use GPT-4 without any restrictions.** The previous tiers of ChatGPT, which are still available for individuals and developers, have usage caps and lower performance. ChatGPT Enterprise removes these limitations and provides the most powerful version of GPT-4 yet.
- **ChatGPT Enterprise also offers enterprise-grade privacy and security.** Unlike some other AI services, OpenAI does not train its models on customer data or conversations and encrypts all data in transit and at rest. ChatGPT Enterprise is also SOC 2 compliant, which means it meets the standards for data protection and privacy.

**Some of the features of ChatGPT Enterprise are:**

- Unlimited access to GPT-4 (no usage caps)
- Higher-speed performance for GPT-4 (up to 2x faster)
- Unlimited access to advanced data analysis (formerly known as Code Interpreter)
- 32K token context windows for 4x longer inputs, files, or follow-ups

React: Performance Optimization para uma melhor experiência do usuário.
Published: 2023-08-29 01:31:15

Este artigo trata sobre técnicas e práticas para melhorar o desempenho e a eficiência das aplicações desenvolvidas em React. Uma aplicação React pode, em determinados cenários, tornar-se lenta e consumir muitos recursos do sistema, que pode prejudicar a experiência do usuário. Portanto, é importante entender alguns conceitos para evitar tais problemas e melhorar a performance do sistema. 

**REACT RENDERING**
As renderizações em React ocorrem quando o estado de um componente ou as suas propriedades mudam, levando a uma atualização na interface do usuário. O processo de renderização envolve a criação de uma representação virtual do DOM (Virtual DOM), comparação dessa representação com o estado anterior do DOM e, em seguida, a aplicação das diferenças no DOM real. 

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/wkiwtfj2qtoidlwhai1u.png)


![React rendering kitchen](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/7fwb0r4i3g63lfxieoxd.png)

1. Triggering a render (delivering the guest’s order to the kitchen).
2. Rendering the component (preparing the order in the kitchen).
3. Committing to the DOM (placing the order on the table).

**PREVENTING WASTED RENDERING**
Um dos maiores problemas de performance no React são renders desnecessários. Para isso, é interessante utilizar:
 
- useMemo() - Recebe dois parâmetros: a função, e as dependências que são atualizadas. Ele memoriza os valores das dependências e compara se permanecem iguais ou se modificaram. Se permanecem, ele não re-renderiza. Evita cálculos desnecessários.

![useMemo code](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/v3t2jcsz3m44e3qjiyx5.png)

- useCallback() - Memoriza funções. Evita re-renderizações desnecessárias de componentes filhos

![useCallback code](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/0p44z43f77n4lmm3ei6t.png)

- Code Splitting: Dividir o código e bundles menores.

- Lazy loading - Permite primeiro um carregamento leve para o usuário, uma tela leve, enquanto baixa/carrega chamadas e componentes pesados por trás. (Ex.: loading components, skeleton, etc.)
The Magic of Mood-Based Playlist Ai
Tags: ai, music, api, news
Published: 2023-08-29 00:06:22

Music is not just a collection of melodies and harmonies. It's a universal language that transcends borders, cultures, and, most importantly, our emotions. We've all experienced that overwhelming surge of nostalgia when a certain song plays or felt instantaneously happy listening to an upbeat track.

## Bridging Beats and Emotions
Why does a melancholic tune on Spotify make us teary, and an energetic one uplift our spirits? The answer lies deep within our brain's neural pathways. When music enters our ears, it isn't merely processed as sound. Our brains interpret these melodies and harmonies, leading to emotional responses. Essentially, music becomes an emotion-translator.

## A Dance of Dopamine
When you stumble upon a Spotify playlist that matches your mood perfectly, there's science at play. Listening to music releases dopamine, the feel-good neurotransmitter. The right song can literally bring joy, thanks to this neurochemical magic. So, when Taranify recommends a mood-based playlist, you're in for a dopamine treat!

## AI: The Modern Maestro
Enter Taranify Playlist AI, the technology making waves in the music world. Gone are the days of manually curating songs. With advanced algorithms, platforms like Taranify can gauge your mood and instantly curate a Spotify playlist tailored just for you. Think of it as having a personal maestro, understanding your feelings and setting them to music.

## The Cultural Canvas
Music and emotions aren't a new affair. Historically, different cultures have used music to express feelings, celebrate, or mourn. From the tribal beats of ancient civilizations to the grand orchestras of the Renaissance, music has always mirrored human emotion. Platforms like Spotify give us a modern twist, offering an endless cultural canvas of tracks to explore.

## The Power of Personalization
Imagine having a Spotify playlist that understands not just your musical taste, but your heart's state. That's the power of mood-based playlists. By aligning with your emotions, it creates a deeply personal listening experience. Every song becomes a reflection of your inner world, making each note resonate deeper.

## From Moods to Melodies
As we progress in the world of AI and tech, the bond between our moods and melodies will only strengthen. Services like Taranify are at the forefront, pioneering a movement where music is more than just sound—it's a mirror to our souls. A world where every emotion has its own soundtrack is not far away.

## To Conclude: An Emotional Encore
Music is an ever-evolving journey, and with the advent of technologies like [Taranify Mood AI](https://www.taranify.com), we're entering an era of emotional encore. So, next time you dive into a Spotify playlist, remember, it's not just tunes you're listening to but a reflection of your very emotions.
My notebook:
Published: 2023-08-28 23:44:04

Now I'm decide to make it my personal notebook, I know this site inst for this way of using. But I will. Idk.

this is my first post and I got nothing to share, but probably next one you be about **SQL**.

I've learned in last 9 months those technologies:

- JavaScript
{ madding REST API using Express.js and some middleware like Multer and use a JSON as DB in my classic Pokedex application }

- Mongoose
{ creating a classic login using a NoSQL db as MongooDB, using JWT and Bcrypt}
 
- HTML/CSS (lmao)
- React.js { create a application to my login API using react (my first contact, please forgive me }

I have so much to learn and so excited for it.
