Tags: apacheage, postgres, postgressql, database
Published: 2023-11-11 10:23:46

In the field of database administration, replication and high availability (HA) are essential components that guarantee system uptime. Strong features are available in PostgreSQL, an open-source relational database management system, for creating high availability configurations and data replication across several servers. We'll look at methods and approaches to get high availability and replication in PostgreSQL in this in-depth article.

**Understanding High Availability:**
The ability of a system to continue functioning and being available despite hardware malfunctions, software problems, or other disturbances is known as high availability. Achieving high availability in PostgreSQL entails configuring the system to reduce downtime and guarantee data integrity.

**Replication Models for PostgreSQL:** PostgreSQL offers a number of replication models, each tailored to satisfy certain needs. Some typical replication models are as follows:

**1. Physical Replication:**
Streaming replication, as it is also called, is the process of replicating the whole PostgreSQL cluster to one or more standby nodes.

- Benefits replicated in real time.

- Ideal for extensive databases.

- Taking into account needs a shared file system in order to replicate.

**Logical Replication:** 
Using a logical decoding method, it replicates particular tables or databases.
Benefits: Greater freedom in selecting replicated tables.
Replicating data selectively is possible with this.
Take into account: In comparison to physical replication, there can be some lag.

**Bi-Directional Replication (BDR):** 
Permits multi-master configurations by enabling bidirectional replication across nodes.
Benefits: Accommodates writes across several nodes.
Perfect for installations that are dispersed geographically.
Take into account: Needs further setup and customization.


**Conclusion**
In conclusion, PostgreSQL high availability and replication are essential for guaranteeing the dependability and robustness of your database architecture. You can select between logical and physical replication types and add further tools for load balancing and automated failover based on your particular needs. You may build a PostgreSQL environment that satisfies the needs of contemporary, always-on applications by adhering to best practices and routinely testing your configuration. This will ensure high availability and effective data replication.

**Introduction**
A robust open-source relational database management system called PostgreSQL is frequently used for managing and storing vital data for a variety of applications, from small-scale projects to extensive business solutions. PostgreSQL administration requires backup and restoration procedures since it is critical to the safety and availability of this data. We'll go over several backup and restore methods in this extensive article to help you protect your PostgreSQL databases.


**Why Do You Backup?**
Prior to delving into tactics, it is imperative to comprehend the significance of consistent backups:

**Data protection:** Human mistake, hardware malfunctions, and accidental data loss are all possible. Backups are a safeguard against losing or corrupting data.

**Disaster Recovery:** Having a backup lets you swiftly restore your database to a previous state in case of a system breakdown or other unforeseen circumstance.

**Database Migration:** When moving databases between servers or settings, backups make the process easier.


**Best Practices:** 

**Test Backups Often:**
Restore backups to a test environment to make sure they are routinely checked.

**Automate Procedures for Backups:**
Use automatic backup processes to prevent human error and guarantee consistency.

**External Storage:**
To guard against physical harm or the loss of the primary server, store backups offsite.

**Observation and Warnings:**
Set up monitoring to get notifications when there are abnormalities or backup failures.

**Backup Procedures for Documents:**
Keep thorough records of your backup and restoration processes so you can resort to them in an emergency.

**Conclusion**
In conclusion, PostgreSQL database administrators must have a strong backup and restoration plan in place to protect data and guarantee business continuity. Operational requirements, recovery time targets, database size, and other considerations all play a role in selecting the best approach. You may reduce the risk of data loss and system failures by putting best practices and a well-thought-out backup strategy into place. This will lay a strong basis for the dependability of your PostgreSQL databases.
CACHE NO LADO DO CLIENTE
Published: 2023-11-11 10:14:13

O armazenamento no lado do cliente é crucial para evitar sobrecarga no servidor e proporcionar maior velocidade na entrega de informações ao usuário. Existem várias formas de realizar isso, considerando o contexto da web.

##COOKIES

Este é um dos primeiros métodos de armazenamento no lado do cliente, sendo usado, na época, de forma geral para cache. Atualmente, é empregado para armazenar informações relacionadas a sessões de usuários, estados e outros dados menores.

##WEB STORAGE

Os cookies apresentam um problema de desempenho, enviando dados a cada nova requisição do cliente de volta ao servidor para verificação. Por isso, surgiram novos métodos, como o Web Storage, que armazena dados com a estrutura de chave e valor, permanentemente ou temporariamente (os dados são apagados ao fechar o navegador). É excelente para armazenar dados simples, como nome e foto de perfil de um usuário.

##INDEXED DB

Esta opção oferece um sistema de banco de dados completo, sendo facilmente utilizado para armazenar estruturas de dados mais complexas, como postagens recorrentes em uma rede social.

##CACHE API

O funcionamento deste método de armazenamento é um pouco diferente, pois apenas armazena respostas HTTP do servidor. No entanto, há algo especial: os service workers. São processos diretamente relacionados ao seu domínio/site de origem, interceptando as requisições do cliente e respostas do servidor, podendo tratá-las conforme desejado pelo desenvolvedor. Assim, os service workers podem interceptar as respostas do servidor e usar o Cache API para armazenamento, permitindo um site completamente offline.

##CONCLUSÕES

Claro que poderíamos nos utilizar de outras ferramentas para tal, como o Redis; contudo, temos um grande leque de soluções disponíveis no contexto de sites web, quase que nativamente (pois essas soluções são, em sua grande maioria, APIs escritas em JavaScript) para economia de recursos, melhoria de desempenho e maior satisfação do cliente. That's all, folks!

In recent years, there has been a noticeable shift of software engineers and developers moving from Windows PCs to macOS devices like MacBooks and iMacs. There are several reasons why macOS is becoming the preferred operating system for programming and development work.

### 1. Performance and Stability 🔋

macOS is based on Unix and has a optimized kernel that provides a smooth and responsive user experience. The hardware and software integration on Macs enables maximum performance and stability. This translates to less time wasted on troubleshooting crashes, bugs, and other system issues.

**_Windows sucks in driver updating and it causes unexpected crashes in PC._**

### 2. Unix-based System ❤️

macOS being Unix-based provides a native terminal and access to powerful Unix command line utilities. This allows developers to work more efficiently on tasks like managing packages, deployments, and configurations. The Unix architecture contributes to the stability and security of macOS as well.

### 3. Better Development Tools 🛠️

The Apple ecosystem offers advanced IDEs (Integrated Development Environments) like Xcode and user-friendly tools for coding, testing, and debugging. Xcode in particular makes iOS and macOS development seamless. Many open source and third-party development tools are optimized for macOS.

### 4. Cross-platform Compatibility 🔄

Macs allow developers to build and test apps for different platforms like iOS, Windows, Android, and more. Technologies like Virtual Machines, emulators, and dual booting (Intel MacBooks support windows ) provide flexibility within macOS to work across diverse software stacks.

### 5. User Experience 📒

The interface, hardware, and overall UX of macOS is polished and intuitive. MacBooks offer premium build quality and battery life, making them pleasant to use for long coding sessions. macOS also offers many accessibility features to customize the user experience.

### 6. Security 🔐

Apple takes a layered approach to security – from the chip level with Apple Silicon to encryption, malware detection, and frequent software updates. This provides peace of mind for developers working on sensitive code and data.

In short, macOS offers the perfect blend of UNIX power, development tools, hardware stability, and elegant UX for modern software engineering needs.

> **So in the last do you prefer Mac or Windows ?**

Setting up Tailwind CSS in React with Vite
Tags: tailwindcss, react
Published: 2023-11-11 08:30:11

TailwindCSS has nowadays become the best solution for styling web applications. I started using it some months back and I just love the flexibility it gives.
In this post, I will show how you can easily set tailwindCSS up and start using in React applications.

I am using Vite CLI to create all my new React applications. Vite is a code build tool created on top of rollup. It provides a cli to create any kind of web application (React, Vue, Solid etc). It has a better performance than CRA or even manually set webpack project. Also hot code replacement is very fast. Below image shows the steps to create the React application.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/0fjmfln2f3g9fhrfrxah.png)

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/5pot1g96wxadrloq6o6u.png)

Once you have application up, you can follow the below steps. 

Below video also walks you through the same steps of setting up tailwindCSS.

{% embed https://youtu.be/-CN-tZzjno0?si=vrEMp5r-rHyRjK1z %}

1. Install tailwindcss and autoprefixer as dev-dependencies.
`npm i tailwindcss autoprefixer --save-dev`
Autoprefixer - This is a postCSS plugin which upon code build, adds vendor prefix to some CSS rules. There are few style attributes which need -webkit or -moz prefix for Chrome and Mozilla browsers. Autoprefixer takes care of them.

2. Run below command to initialize tailwindcss
`npx tailwindcss init -p`
This will create 2 files

postcss.config.js (-p helps to create this file)
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/1uv3qm3bpu3exvzilpp5.png)

tailwind.config.js
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/1jd036ay9rpe2fxi88cj.png)

3. In tailwind.config.js, update the content value with the path which contains the tsx,jsx files. Only the file path mentioned here will be considered by tailwindCSS.
`content: ["./src/**/*.{js,jsx,ts,tsx}"],`
If any changes are to be done to exisiting properties of tailwind, you can add them in theme section. 

4. Open App.css or index.css and add 
`@tailwind base;`
`@tailwind components;`
`@tailwind utilities;`

You are ready to use tailwind css classNames in your code now.
If you are using VS code, you can also install an extension "Tailwind CSS Intellisense" which will help in auto suggesting the classNames.

You are all set. Happy Coding.

Published: 2023-11-11 08:20:50

## Create your own ChatGPT

OpenAI is rolling out the custom version of ChatGPT to create your own chatGPT version. Anyone can easily build their own GPT—no coding is required. You can make them for yourself, just for your company’s internal use, or for everyone. Creating one is as easy as starting a conversation, giving it instructions and extra knowledge, and picking what it can do, like searching the web, making images or analyzing data.

This is a good feature to roll out because one can create GPTs without actual code, and one can integrate other third-party plugins, and databases to automate the work.

## Earn from creating your own GPTs
Yeah, you read it right, one can create his/her own GPTs and correspondingly sell or showcase them in the community over the GPT store.
OpenAI is about to launch in the GPT store just like the Apple or Android store for everyone to share their custom GPTs and monetise their work.

## Upgraded GPT4 data till April 2023
This is inevitable, OpenAI will keep on looking the ways to monetise the platform, especially chatGPT. OpenAI upgraded version now has the model trained till April 2023, meaning if you using the free version of chatGPT the GPT model will answer till the data belonging to September 2022 which has been increased to April 2023 in the upgraded version.

One can create own GPT without code, one can sell GPT on store and one can integrate more plugins and databases in the GPT to customise GPT.

Journey of SkyPress-Pt 1: Review
Tags: webdev, javascript, beginners, react
Published: 2023-11-11 08:20:31

Hello, viewers! or I readers I suppose, I'm... uh, just call me Keys. I'm learning ReactJS and mastered the core front-end tech + PHP. Ok no more nonsense, let's start **now**

In this part, we aren't going to see any code or are we? 'Cause this is my present self which'll be my past self. Ok for real, let's start now

So why am I doing a review? Why not get into code now? What even is SkyPress?!

answers, from the first to last question: 

1. Because I want all of you to understand what I've been building prior to this post 
2. I feel I need to do a review
3. It's like wordpress but not quite. It's more like a GUI to make a HTML page, with styles, and **probably** JS

I already build the landing page and now building the heaviest part, the designer using react. Problems come(as they often do)

1. React won't display anything, solved by wrapping JSX in the return statement(yes, I'm sloppy)
2. React don't display anything in a component, if you are intrigued by this consider checking my stackoverflow question where I explain this problem in depth, not yet solved

OH GOD! I AM SO SLOPPY! I FOUND IT, THE ANSWER TO NUMBER 2!

I forgot to pass a prop in react

```
<button type='button' className={'bg-primary text-white p-2 m-1 rounded'+extraClasses}>{content}</button>
```
See that content props there? I forgot to pass it as a attribute in the JSX, and now I know that we also could do this

`<Btn>Hello</Btn>`

rather than this

`<Btn content='Hello'></Btn>`

The former could be done by passing the children props to the element declaration

```
const Btn = ({children}) => {
  return (
    <button type='button'>{children}</button>
  );
}
```
and just pass the text in between the angled brackets like good 'ol HTML

anyways I must prepare for my math course and start to work on my language project 

Ciao!
