Um ponteiro é uma variável que armazena o endereço de memória de outra variável. Em outras palavras, ao invés de armazenar diretamente um valor, um ponteiro armazena a localização na memória onde esse valor está armazenado. Essa habilidade permite que o programa manipule diretamente os dados na memória, o que é extremamente útil para uma série de operações avançadas.

Podemos listar como as principais aplicações dos ponteiros:

Alocação Dinâmica de Memória:
Permite que o programa aloque memória durante a execução usando funções da biblioteca padrão, como malloc, calloc, realloc e free.

Manipulação de Arrays e Strings:
Facilita o acesso e modificação de elementos de arrays e strings.
Arrays e strings em C são manipulados com facilidade através de ponteiros.

Estruturas de Dados Dinâmicas:
Implementação de listas encadeadas, árvores, pilhas, filas e outras estruturas dinâmicas.
Ponteiros permitem que essas estruturas cresçam e diminuam de tamanho conforme necessário.

Passagem de Parâmetros para Funções:
Permite a passagem de grandes estruturas de dados ou arrays para funções sem a necessidade de cópia, melhorando a eficiência.
As funções podem modificar diretamente os argumentos passados via ponteiros.

Exemplo utilizando a linguagem de programação C:

#include <stdio.h>
#include <stdlib.h>

int main() {
    int *ptr; //aqui declaramos o ponteiro utilizando o operador * antes do nome da variável
    int n, i;

    printf("Digite o número de elementos: ");
    scanf("%d", &n);

    // Alocando memória para n inteiros
    ptr = (int*) malloc(n * sizeof(int));

    if (ptr == NULL) {
        printf("Erro de alocação de memória!\n");
        return 1;
    }

Exemplo de manipulação de Arrays:

#include <stdio.h>

void printArray(int *arr, int size) {
    for (int i = 0; i < size; ++i) {
        printf("%d ", *(arr + i));
    }
    printf("\n");
}

int main() {
    int arr[] = {1, 2, 3, 4, 5};
    int size = sizeof(arr) / sizeof(arr[0]);

    printArray(arr, size);

    return 0;
}

    printf("Digite os elementos do array:");
    for (i = 0; i < n; ++i) {
        scanf("%d", ptr + i);
    }

    printf("Os elementos do array são:");
    for (i = 0; i < n; ++i) {
        printf("%d ", *(ptr + i));
    }

    // Liberando a memória alocada
    free(ptr);

    return 0;
}

Overview of Generative AI - Part1
Tags: ai, chatgpt, programming
Published: 2024-05-23 19:08:39

<p>
<br>Generative artificial intelligence is artificial intelligence capable of generating text, images or other data using generative models, often in response to prompts. Generative AI models learn the patterns and structure of their input training data and then generate new data that has similar characteristics.</p>
<p>&nbsp;</p>
<p>Generative AI is artificial intelligence capable of generating text, images and other types of content. What makes it a fantastic technology is that it democratizes AI, anyone can use it with as little as a text prompt, a sentence written in a natural language.</p>
<p>&nbsp;</p>
<p>how large language models work<br><br>&nbsp;</p>
<ul>
<li><strong>Tokenizer, text to numbers</strong>: Large Language Models receive a text as input and generate a text as output. However, being statistical models, they work much better with numbers than text sequences. That’s why every input to the model is processed by a tokenizer, before being used by the core model. A token is a chunk of text – consisting of a variable number of characters, so the tokenizer's main task is splitting the input into an array of tokens. Then, each token is mapped with a token index, which is the integer encoding of the original text chunk.</li> 

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/d89pql069z8ba4ggihbt.png)

<li><strong>Predicting output tokens</strong>: Given n tokens as input (with max n varying from one model to another), the model is able to predict one token as output. This token is then incorporated into the input of the next iteration, in an expanding window pattern, enabling a better user experience of getting one (or multiple) sentence as an answer. This explains why, if you ever played with ChatGPT, you might have noticed that sometimes it looks like it stops in the middle of a sentence.</li>
<li><strong>Selection process, probability distribution</strong>: The output token is chosen by the model according to its probability of occurring after the current text sequence. This is because the model predicts a probability distribution over all possible ‘next tokens’, calculated based on its training. However, not always the token with the highest probability is chosen from the resulting distribution. A degree of randomness is added to this choice, in a way that the model acts in a non-deterministic fashion - we do not get the exact same output for the same input. This degree of randomness is added to simulate the process of creative thinking and it can be tuned using a model parameter called temperature.</li>

Emmet: A Productivity Booster for Web Developers.
Tags: css, html, webdev, emmet
Published: 2024-05-23 18:56:41

Emmet is a productivity tool for web developers, particularly those who work with HTML, CSS, and XML. It allows developers to write code snippets that can be expanded into full, valid code blocks with a single keystroke. This tool is widely integrated into many popular text editors and Integrated Development Environments (IDEs).

---

## Abbreviation Expansion.
**Emmet** uses short syntax to generate HTML and CSS code rapidly. As an example
```
<body>
  div>ul>li*3
<body>
```
It will produce
```
<body>
<div>
    <ul>
        <li></li>
        <li></li>
        <li></li>
    </ul>
</div>
<body>
```

## Tag wrapping.
It can wrap existing text of code with HTML tags, speeding up the process of structuring content.
[Link to the wrap with abbreviation examples](https://docs.emmet.io/actions/wrap-with-abbreviation/)

## Code snippets.
**Emmet** includes many built-in snippets for common code patterns and allows users to create custom snippets.
Custom code snippet:
```
{
    "html": {
        "snippets": {
            "btn": "<button class=\"btn\">${1:Submit}</button>"
        }
    }
}
```
Typing `btn` and expanding it will produce:
```
<button class="btn">Submit</button>
```

## Attributes and Text.
Abbreviations can include attributes and text.
```
a[href="https://example.com"]{Example}
```
It will produce:
```
<a href="https://example.com">Example</a>
```

## CSS support.
**Emmet** also supports CSS, allowing for rapid writing of style rules. For instance in CSS file
`* {
  m0
}`
It will produce:
```
* {
  margin: 0;
}
```

## Dynamic Values.
**Emmet** can generate dynamic values such as incrementing numbers, making it useful for creating lists, IDs, classes, and more.
```
<div>
  ul>li.item$*3
</div>
```
It will produce:
```
<div>
  <ul>
    <li class="item1"></li>
    <li class="item2"></li>
    <li class="item3"></li>
  </ul>
</div>
```

**Emmet** significantly speeds up coding by reducing the amount of repetitive typing required, allowing developers to focus more on design and logic rather than the boilerplate code.

How to call out contributions to your new, open source releases
Tags: release, programming, productivity, opensource
Published: 2024-05-23 18:40:25

OpenProject is committed to a release cycle of every four weeks. Is this ambitious? Yes. Does it offer them special opportunities despite the extra effort? Also, yes.

One of them is the chance to call out those who contributed to bug fixes, feature requests and feedback, and other types of support in that cycle. This includes companies, institutions, and individuals by name.

In the latest release ([14.1.0](https://www.openproject.org/docs/release-notes/14-1-0/)), OpenProject shares the following:

## Contributions

> A very special thank you goes to our sponsors for the features and improvements of this release:
> - The City of Cologne for sponsoring features on project attributes.
> - Deutsche Bahn for sponsoring the OneDrive/SharePoint integration.
> - German Federal Ministry of the Interior and Home Affairs (BMI) for sponsoring the features on progress reporting.

> Also a big thanks to our Community members for reporting bugs and helping us identify and provide fixes. Special thanks for reporting and finding bugs go to Marc Burk, Silas Kropf, and Hanley Loller.

> Last but not least, we are very grateful for our very engaged translation contributors on Crowdin, who translated quite a few OpenProject strings! This release we would like to highlight user Syvert who has done an outstanding number of translations for the Norwegian language in recent weeks.

> Would you like to help out with translations yourself? Then take a look at our [translation guide](https://www.openproject.org/docs/development/translate-openproject) and find out exactly how you can contribute. It is very much appreciated!

Thus, the OpenProject Community is strong and growing. The software is open source, and the company is open in the way that it takes and responds to feedback. The door is open.

Have you considered calling out your contributors on new releases?
Open source: The world of selfless collaboration
Tags: opensource, programming, collaboration
Published: 2024-05-23 18:39:23

Whether you're a developer or everyday user enjoying the conveniences of modern technology, open source projects likely play a crucial role in your digital experience. From the smart TV in your living room to the information system at your workplace, and even the complex systems within your car or the coffee machine brewing your morning joy – open source is the silent engine that helps different things work together better. It's the secret sauce driving **teamwork** and innovation in many areas.

ChatGPT would describe open source as follows: _“An open source project is like a big box of Legos that everyone can play with, build on, and share their creations with others for free!”_

Typically, these **"Legos"** represent software components that can be reused across various use cases and projects. Many commercial enterprise software products leverage these open source components. The explanation behind this is simple: why spend time reinventing the wheel when a desired feature often already exists in the open source world? Embracing open source projects is not only a time-saving practice but is actively encouraged within the developer community.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/noy9jrgnsx053xdq7vsh.png)

Want to know more about enterprises using open source? Make sure to checkout: [Tech Giants Fueling Open Source Innovation](https://openpledge.io/companies-supporting-open-source.html).

Open source thrives on the power of community collaboration. It's not just about lines of code; it's about a global community coming together to solve problems, share knowledge, and collectively improve software for everyone. This collaborative spirit extends to the principles of freedom and accessibility, where anyone can access, modify, and distribute open source software, fostering an inclusive and transparent environment.

Moreover, open source is not only about building on existing creations but also ensuring the **security** and **reliability** of the software. The transparent nature of open source allows for continuous audits, often making it more secure than closed-source alternatives. Open source projects evolve based on user feedback, ensuring adaptability and relevance in the ever-changing landscape of technology.

Read more on security risks of open source in an article [From Thriving to Forgotten: The Dynamics of Abandoned Open Source Projects](https://openpledge.io/abandoned-open-source-projects.html).

So, whether you're a seasoned developer or an everyday user, open source is not just a silent engine; it's a dynamic, collaborative force that powers the digital world we live in.
Creating route directory in Slim Php Framework
Tags: login, php, slim, framework
Published: 2024-05-23 18:38:17

Hello Everyone,

I have discussed on creating route directory in slim php framework. It makes easy to organize or modular your slim project.

Let's go,

**STEP 1:**
Firstly, copy your code in `public/index.php`:

```
$routes = glob(__DIR__ . "/../routes/*.php");

foreach($routes as $route)
{
     (require $route)($app);
}
```

**STEP 2:**
In second step, we'll create routes directory in our slim project directory and also create `routes/web.php` file:
Like this,

```
<?php

use Slim\App;

return function (App $app)
{
     $app->get("/your-route", function ($request, $response, $args){
           $response->getBody()->write("Hello, I am in your route");
           return $respones;
     });
};
```


I hope you to enjoy for creating such routes separate files that may be slim code organizable, readable.


Thank you for giving your valuable time to read this!✨

VS Code for Note-Taking
Tags: vscode, tutorial, beginners, notes
Published: 2024-05-23 18:23:13

## Using VS Code for Note-Taking

### 1. **Markdown Support**
VS Code has excellent support for Markdown, making it a great choice for note-taking. You can create Markdown files (.md) to organize your notes, ideas, and thoughts. Markdown allows you to format text, create lists, add headings, and include code snippets.

### 2. **Workspace Setup**
1. Open VS Code and create a new folder for your notes.
2. Save the folder as a workspace (File > Open Folder). This step ensures that you can manage multiple notes within the same workspace³.

### 3. **File and Folder Organization**
- Create subfolders within your workspace to categorize your notes. For example:
    - `Personal`
    - `Work`
    - `Projects`
    - `Ideas`
- Use descriptive folder names to make it easy to find specific notes later.

### 4. **Task Management**
VS Code allows you to automate tasks using the built-in **Tasks** feature. You can configure tasks to run scripts, start processes, and perform various actions. Here's how:

1. Create a `tasks.json` file in the `.vscode` folder within your workspace.
2. Define tasks using the appropriate task runner (e.g., TypeScript Compiler, linters, build systems).
3. Execute tasks directly from VS Code without entering the command line¹.

### 5. **Repetitive Tasks and Automation**
- Use tasks to automate repetitive actions. For example:
    - Compile TypeScript files automatically when you save them.
    - Run linters to check code quality.
    - Trigger build processes for your projects.

### 6. **Project Management**
- Create separate folders for each project within your workspace.
- Organize project-related notes, code snippets, and documentation in these folders.
- Use Markdown files to maintain project-specific to-do lists, milestones, and progress updates.

### 7. **Getting Things Done (GTD) Methodology**
- Apply GTD principles to your note-taking process:
    - Capture: Quickly jot down ideas, tasks, and notes.
    - Organize: Sort your notes into relevant folders.
    - Review: Regularly review and update your notes.
    - Prioritize: Identify high-priority tasks and focus on them.

Remember that VS Code is highly customizable, so explore extensions and settings that enhance your note-taking experience. Happy note-taking! 📝✨⁴
