Tags: datascience, nlp
Published: 2023-06-20 13:47:59

Natural Language Processing (NLP) is a subfield of electronic thinking (man-made knowledge) and semantics that bright lights on the correspondence between computers and human language. It includes the improvement of calculations and models to empower PCs to comprehend, decipher, and create human language in a way that is significant and helpful.

NLP plays a crucial role in [data science](https://prerogative.in/blog/what-is-datascience/) by providing tools and techniques to process and analyze vast amounts of textual data, allowing valuable insights to be extracted. Here's an overview of how NLP enables computers to understand, interpret, and generate human language:

- Text Preprocessing Techniques: Explore the various preprocessing techniques used in NLP, such as tokenization, stemming, lemmatization, and stop word removal. Discuss their importance in preparing text data for analysis.

- Sentiment Analysis: Explain how NLP can be used for sentiment analysis, which involves determining the sentiment or emotion expressed in text data. Discuss the applications of sentiment analysis in fields like social media monitoring, customer feedback analysis, and brand reputation management.


- Topic Modeling: Introduce topic modelling algorithms, such as Latent Dirichlet Allocation (LDA) and Non-Negative Matrix Factorization (NMF), and their role in uncovering hidden themes or topics within a large corpus of text data. Provide examples of how topic modelling can be applied, such as in document clustering or content recommendation systems.


- Text Classification: Explore the use of NLP in text classification tasks, including sentiment classification, spam detection, and intent recognition. Explain popular algorithms like Naive Bayes, Support Vector Machines (SVM), and deep learning models like Recurrent Neural Networks (RNNs) or Transformers.

- Text Generation: Discuss the advancements in text generation techniques, such as language models like OpenAI's GPT, and their applications in chatbots, content generation, and machine translation. Highlight the challenges and ethical considerations in generating human-like text.

- NLP and Unstructured Data: Highlight how NLP enables the analysis of unstructured data, such as social media posts, customer reviews, or medical records. Explain the value of extracting insights from unstructured data sources and the impact on decision-making.


- Future Trends and Challenges: Discuss emerging trends and challenges in NLP, such as multilingual processing, domain adaptation, and handling sarcasm or irony in the text. Explore ongoing research and potential applications of NLP in areas like healthcare, finance, and legal industries.

Moreover, a [Data Science Internship](https://prerogative.in/internship/data-science-internship/) can help you know about Natural Language Processing and many other contents related to Data Science in detail, and that too from experts with a deeper knowledge of this.
Uncanny visual symbols of a git conflict explained
Tags: git, webdev, beginners, github
Published: 2023-06-20 13:24:37

Git is such a popular Version Control System. It needs no introduction.<br />
Software development is a collaborative task where git helps track and versions the changes made. When working in a team setting, conflicts are frequent visitors. I am not refferring to people coming to blows, but Git encountering lines in files that have received edits from two branches during a merge operation.

Therefore a _git conflict_ arises **when two separate branches have made edits to the same line in a file**, or **when a file has been deleted in one branch but edited in the other**.

When you inspect an affected file in a merge conflict, there are strange symbols that appear in the lines where the conflict has occured. Ideally when git encounters a conflict during a merge, it will edit the content of the affected files with visual indicators that mark edits received from both sides of the involved branches.

These symbols are `<<<<<<<`, `=======` and `>>>>>>>`, like in the example illustration below of a merge conflict:

![Merge conflict symbols](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/mwoxnsb13aylkwqlfiec.png)

## What these symbols mean

Its simple.<br />
**`=======`** is a symbol that separates edits recived from both branches. The content above and enclosed between **`<<<<<<<`**, and **`=======`** is the receiving branch. More specifically the branch that is currently checked out and receiving work from another branch.<br />
And the content below **`=======`**, enclosed between **`=======`** and **`>>>>>>>`**, is the merging branch.

It is helpful to search a project for these symbols during a merge to find where conflicts need to be resolved.

To fix a conflict, you as a developer has to decide which either side of the **`=======`** symbol you want to stick with. Once decided, you can replace the symbols with the content you have chosen. Once you are certain you have fixed all the conflicts pointed out by Git, you can mark resolved by runnig `git add` on the file(s) and finally `git commit` to complete the merge operation.

If somehow later this merge turns to be a mistake, you might want to equip yourself with git techniques to undo. I wrote an article that teaches exactly that: [how to undo mistakes in Git](https://dev.to/smitterhane/turn-around-your-git-mistakes-in-17-ways-2mn1).

Thanks for reading.

Getting Started with Git-


𝗴𝗶𝘁 𝗶𝗻𝗶𝘁 : This is the very first command you'll need to use when starting a new project. It initializes a new Git repository in your current directory.

𝗴𝗶𝘁 𝗰𝗹𝗼𝗻𝗲 <𝗿𝗲𝗽𝗼> : To work on an existing project, you'll want to clone (copy) it to your local machine. This command does that.

𝗠𝗮𝗸𝗲 𝗖𝗵𝗮𝗻𝗴𝗲𝘀
#Git
𝗴𝗶𝘁 𝘀𝘁𝗮𝘁𝘂𝘀 : Before making or after making changes, it's good practice to check the status of your files. This command will show you any changes that are currently unstaged.

𝗴𝗶𝘁 𝗮𝗱𝗱 <𝗳𝗶𝗹𝗲𝗻𝗮𝗺𝗲> : After you've made some changes to your files, you'll want to stage them for a commit. This command adds a specific file to the stage.

𝗴𝗶𝘁 𝗮𝗱𝗱 . 𝗼𝗿 𝗴𝗶𝘁 𝗮𝗱𝗱 -𝗔 : Instead of adding files one by one, you can add all your changed files to the stage with one command.

𝗴𝗶𝘁 𝗰𝗼𝗺𝗺𝗶𝘁 -𝗺 "𝗖𝗼𝗺𝗺𝗶𝘁 𝗺𝗲𝘀𝘀𝗮𝗴𝗲" : Now that your changes are staged, you can commit them with a descriptive message.

𝗕𝗿𝗮𝗻𝗰𝗵𝗶𝗻𝗴

𝗴𝗶𝘁 𝗯𝗿𝗮𝗻𝗰𝗵 : This command will list all the local branches in your current repository.

𝗴𝗶𝘁 𝗯𝗿𝗮𝗻𝗰𝗵 <𝗯𝗿𝗮𝗻𝗰𝗵𝗻𝗮𝗺𝗲> : This command creates a new branch.

𝗴𝗶𝘁 𝗰𝗵𝗲𝗰𝗸𝗼𝘂𝘁 <𝗯𝗿𝗮𝗻𝗰𝗵𝗻𝗮𝗺𝗲> : If you want to switch to a different branch, use this command.

𝗴𝗶𝘁 𝗺𝗲𝗿𝗴𝗲 <𝗯𝗿𝗮𝗻𝗰𝗵𝗻𝗮𝗺𝗲> : Once you've finished making changes in a branch, you'll want to bring those changes into your main branch (usually master). This command does that.

𝗥𝗲𝗺𝗼𝘁𝗲 𝗥𝗲𝗽𝗼𝘀𝗶𝘁𝗼𝗿𝗶𝗲𝘀

𝗴𝗶𝘁 𝗽𝘂𝘀𝗵 𝗼𝗿𝗶𝗴𝗶𝗻 <𝗯𝗿𝗮𝗻𝗰𝗵𝗻𝗮𝗺𝗲> : This command sends your commits to the remote repository.

𝗴𝗶𝘁 𝗽𝘂𝗹𝗹 : If other people are also working on your project, you'll want to keep your local repo up-to-date with their changes. This command fetches and merges any changes from the remote repository.

𝗴𝗶𝘁 𝗿𝗲𝗺𝗼𝘁𝗲 -𝘃 : To check which remote servers are connected with your local repository.

𝗞𝗲𝘆 𝗗𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝗰𝗲𝘀

𝗴𝗶𝘁 𝗳𝗲𝘁𝗰𝗵 𝘃𝘀 𝗴𝗶𝘁 𝗽𝘂𝗹𝗹: Both download data from a remote repository. However, git fetch just downloads it without integrating it, while git pull also merges it into your local files.

𝗴𝗶𝘁 𝗺𝗲𝗿𝗴𝗲 𝘃𝘀 𝗴𝗶𝘁 𝗿𝗲𝗯𝗮𝘀𝗲: Both incorporate changes from one branch to another. git merge combines the source and target branches via a new commit, whereas git rebase moves or combines commits to a new base, making a cleaner history.

𝗴𝗶𝘁 𝗿𝗲𝘀𝗲𝘁 𝘃𝘀 𝗴𝗶𝘁 𝗿𝗲𝘃𝗲𝗿𝘁: Both are used to undo changes. git reset discards local changes completely, while git revert undoes public changes by creating a new reversing commit, thereby preserving history.

Git is an extremely powerful tool with plenty more commands and options.

However, this guide gives you a good start and reference point as you continue to explore and leverage Git for your version control needs.

O que é um webhook?
Tags: beginners, devrel, programming
Published: 2023-06-20 12:25:41


Um webhook é uma forma de comunicação em que um servidor envia solicitações HTTP para um cliente em resposta a eventos ou atualizações ocorridas no servidor. É uma maneira eficiente de receber informações em tempo real, eliminando a necessidade de consultas repetidas (polling).


Suponha que voce tenha um site de comércio eletrônico. Os clientes enviam pedidos por meio da API gateway, que encaminha as transações de pagamento para o serviço de pagamento. O serviço de pagamento, por sua vez, se comunica com um provedor de serviços de pagamento externo (PSP) para concluir as transações.

Existem duas maneiras de lidar com a essa comunicação:

🔹 1. Polling 

Após enviar a solicitação de pagamento, o serviço de continua perguntando sobre o status da transação. Após várias tentativas, o serviço finalmente retorna o status.

**O polling possui duas desvantagens:**

- O polling constante do status requer recursos do serviço.
- A comunicação direta com o serviço de pagamento, cria vulnerabilidades de segurança.

🔹 2. Webhook

Podemos registrar um webhook no serviço. Isso significa: me avise quando uma determinada URL houver atualizações na solicitação. Quando o serviço concluir o processamento, ele invocará a solicitação HTTP para atualizar o status da transação.

Dessa forma, o paradigma de programação é alterado e o serviço não precisa mais desperdiçar recursos para consultar o status do pagamento.

**E se o serviço nunca retornar a chamada? **

Podemos configurar um job de limpeza para verificar o status do pagamento a cada hora.

Os webhooks são frequentemente chamados de APIs reversas ou APIs de push, pois o servidor envia solicitações HTTP para o cliente. Precisamos prestar atenção a três coisas ao usar um webhook:

1 - Projetar uma API adequada para o serviço chamar.

2 - Configurar regras adequadas na API gateway por motivos de segurança.

3 - Registrar a URL correta no serviço.

**Branches**

**Category**: The first thing to do when naming a branch in git, You have to give it a category. The following are the different categories of git naming.
 
**Feature**: Used for adding, refactoring, or removing a feature.
**Bugfix**: Used for fixing a bug.
**Hotfix**: Used for giving the codes a temporary solution. (Usually because of an emergency).
**Test**: Used for experimenting outside of a ticket.
**Wip**: For a work in progress.

**Reference**: The second thing to do is to give the branch a reference which begins with a “/” or “-” sign and then the reference. If there is no reference, just add “/no-ref”. 
Using separators such as “category/no/ref” or “category-no-ref”, improve the readability, but remember to be consistent with the chosen sign. 

**Description**: Depending on the sign you chose to go with between “/” and “-”, after the reference you put another sign, followed by a short description of your message. This description should be “Kebab-cased”, (meaning: a programming variable naming convention, where the space between words and any special character are replaced with a dash “-”). 
**Branch naming example:** 
For adding, refactoring, removing a feature use
**git branch feature/issue-10/create-new-button**

For fixing a bug use
**Git branch bugfix/issue-20/signup-button-overlap**

For fixing a bug really fast as a temporary solution use
**Git branch hotfix/issue-30/login-button-not-working**

For experimenting outside of an issue use
**Git branch test/no-ref/refactor-login-component**




![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/a6btypufoudstjonz69r.png)
**Commits**

**Category**: The first thing to do when naming a commit in git, You have to give it a category. The following are the different categories of commit naming.
 
**Feat**: Used for adding a new feature.
**Fix**: Used for fixing a bug.
**Refactor**: Used for changing the codes for performance 
**Chore**: Used for everything else.


**Description**: After the category, the colon sign (:) is written to announce the commit description. 

**Statement**: After the colon, a commit description follows in the form of a short statement describing the changes made. Statements are separated by a semi-colon (;).

**Commit naming example: **
**Git commit -m”category: added new image; replaced old footer”**

Basic about Ruby C API
Tags: ruby, rails, gem
Published: 2023-06-20 11:53:07

### Creating a Gem using Ruby C API

Sometimes we want to use a lib built with `C` language without any `Ruby` version, to make this we'll find a gem that integrates the lib `C` with `Ruby`. But, how this Gem was built?

In this article I'll show how to make this, using as an example the project [musicrb](https://github.com/juneira/musicrb/tree/v0.0.0), this Gem uses the lib of `C` [vlc](https://www.videolan.org/vlc/index.pt_BR.html) to play music on Ruby.

### How is possible to integrate Ruby and C?

It's simple: `Ruby` is built using `C`, so we'll build a shared lib to the interpreter of `Ruby` use.

But do not trust in me, see the [repository of language](https://github.com/ruby/ruby)!

### Basic about Ruby C API

Before starting to code our lib, we'll see some features in [Ruby C API](http://silverhammermba.github.io/emberb/c/) that we will use (p.s.: this tutorial is very basic if you want deep in this theme, my recommendation is the book [Ruby Under a Microscope](https://www.amazon.com.br/Ruby-Under-Microscope-Illustrated-Internals/dp/1593275277)). 

#### VALUE

See **VALUE** as a pointer to a `Ruby's Object`, since the `Ruby` is dynamic this feature is required. Then `String`, `Number`, `Class`, `Module` ... are accessed and modified by `VALUE` through functions of `Ruby C API`.

This is an example using `VALUE` as a pointer to `String`:

```ruby
VALUE x;
x = rb_str_new_cstr("Hello, world!");

VALUE str;
str = rb_sprintf("pi = %f. %"PRIsVALUE" inspected: %+"PRIsVALUE, M_PI, x, x);

/* pi = 3.141593. Hello, world! inspected: "Hello, world!" */
```

We can see that isn't required to pass the type of VALUE to methods like a program`Ruby`!

#### DEFINE

The Gem `musicrb` has a `class` named `Music`, and has two static methods: `play` and `stop`.

Define this `class` and `methods` using `Ruby` is very simple:

```ruby
class Music
  def play
    # Implementation ...
  end

  def stop
    # Implementation ...
  end
end
```

The code in `C` will be like this:

```c
// Headers ...

// Global variables ...
VALUE rb_cMusic;

VALUE
rb_music_stop(VALUE msc)
{
  // Implementation ...
}

VALUE
rb_music_play(VALUE msc, VALUE rpath)
{
  // Implementation ...
}

void
Init_musicrb(void)
{
  rb_cMusic = rb_define_class("Music", rb_cObject);
  rb_define_singleton_method(rb_cMusic, "play", rb_music_play, 1);
  rb_define_singleton_method(rb_cMusic, "stop", rb_music_stop, 0);
}

```

`rb_define_class`: Define a class named "Music" that has a heritage with "Object".
`rb_define_singleton_method`: Define a singleton method to class "Music", in other words, a method of class. The last parameter of the function is the number of args.

Again, don't trust me!
See here the [code](https://github.com/juneira/musicrb/blob/v0.0.0/ext/musicrb/musicrb.c).

### Next steps

Okay, we already see the basics about the `Ruby C API`, but how to compile and test this code?

This post is already too long... I will follow up on the subject in the next article!

Goodbye, see you soon!
