Paying for full-time servers for applications that go through usage spikes and troughs? Seems like a waste of money and energy.

Apps built with node.js frameworks like Express or KOA can easily be exposed as functions available to the public via API Gateways that have been correctly configured for security and scale with the Nitric CLI.

Rather than relying on dedicated servers that run continuously, Nitric provisions the necessary resources only when your functions are triggered by incoming requests. This architecture eliminates the need to manage and maintain full-time servers, freeing you from the overhead and enabling scale.

Nitric provisions auto-scaling resources in the cloud so you can concentrate on writing code and building features. This streamlined development workflow saves you time and effort, enabling faster iterations and enhancing your overall productivity.

BRIEF SUMMARY ON OBJECTS IN OOP
Published: 2023-07-10 20:35:59

Object-oriented programming (OOP) is a programming paradigm that emphasizes the use of objects, which are instances of classes, to represent and manipulate data. In OOP, objects are the basic building blocks of a program, and they encapsulate data and behavior into a single entity.

###The main characteristics of objects in OOP are:

1. Encapsulation: Objects encapsulate data and behavior into a single entity. This means that the data and the methods that operate on the data are bundled together in an object, and the object controls access to its internal state.

2. Inheritance: Objects can inherit properties and behavior from other objects. Inheritance allows objects to reuse code and to specialize behavior based on their class hierarchy.

3. Polymorphism: Objects can take on many forms and can be used interchangeably. Polymorphism allows objects to be treated as if they were instances of their superclass or any of their subclasses.

4. Abstraction: Objects abstract away complex details and provide a simpler interface to the outside world. Abstraction allows objects to be used without knowing how they are implemented or how they work internally.

###How to creat an object in oop:
To create an object in OOP, you first define a class, which is a blueprint or template for creating objects. A class defines the data and behavior that objects of that class will have. Once you have defined a class, you can create objects of that class by instantiating it with the `new` keyword.

For example, consider a class `Person` that represents a person's name and age:

```
class Person {
  String name;
  int age;

  public Person(String name, int age) {
    this.name = name;
    this.age = age;
  }

  public String getName() {
    return name;
  }

  public int getAge() {
    return age;
  }
}
```

To create a `Person` object, you would call the constructor of the `Person` class:

```
Person john = new Person("John", 30);
```

This creates a `Person` object named `john` with a name of "John" and an age of 30.

Once you have created a `Person` object, you can access its data and behavior using the dot notation:

```
String name = john.getName();
int age = john.getAge();
```

This retrieves the name and age of the `john` object using the `getName()` and `getAge()` methods.

###Conclusion:
In summary, objects in OOP are fundamental units of code that encapsulate data and behavior. They provide a way to model complex systems in a modular way and to reuse code through inheritance and polymorphism. By using objects, you can create more maintainable and extensible software systems.

Object-Oriented Programming: Classes, Explained for Tech Newbies
Published: 2023-07-10 19:57:07

**Introduction**
Object-Oriented Programming (OOP) is a popular programming paradigm used to develop software applications. At the core of OOP is the class, which is a fundamental building block for creating objects and defining their behavior. 

In this article, we'll take a beginner-friendly look at OOP classes and explore what they are and how they work. 

**What is an OOP Class?** 

An OOP class is a blueprint or template for creating objects. It defines the attributes (data) and methods (behavior) that an object of that class will have. Think of a class as a blueprint for a house and an object as an actual house that is built using the blueprint. 

OOP classes are used to create objects that represent real-world entities, such as cars, customers, and bank accounts. For example, a Car class might have attributes such as make, model, and year, and methods such as start, stop, and accelerate.

**How Do OOP Classes Work?** 

In OOP, every class is defined in a separate file with the same name as the class. For example, a class named Car would be defined in a file named Car.java. The code within the class file is organized into sections called members, which include fields, constructors, and methods. 

Fields are variables that store data, such as the make and model of a car. Constructors are special methods that are used to create new objects of a class. Methods are functions that define the behavior of the object, such as starting the car's engine.

**Conclusion** 

OOP classes are fundamental building blocks for creating objects and defining their behavior. They define the attributes and methods that objects of that class will have, and can be used to represent real-world entities in your OOP code.

Often I've come across what can only be describe as a **Beg-Ad**. That's:

> I built something, please, pretty please, buy my thing!

Now you might be thinking, it's free, it's open source, I'm not selling anything. But the truth is you are selling yourself, and the best ad isn't one where you streak through the night hoping people will see you. Want to do it in a refined and tasteful yet visible way.

> So what's the best way to do so without coming across as spammy and self-promotional?

Let's say you have a `homomorphic enabled analytic event testing` solution.

So, you wait. And then wait, and then likely wait some more, and potentially months or years from now someone might ask "Hey I really need an open source tool to monitor homomorphic enabled analytic event testing, what's available".

Which is your tool, OMG, someone wants my tool.

Although, the actual ask is unfortunately going to be instead: "I have no idea what the problem I'm having is but it looks like ....random gibberish..." and then that's the moment you are like "OMG, that's my thing, that's what we do, do you want me to share that with you", and then you share it, and everyone is happy!

If you post it now without waiting, some people might see it, but almost no one will remember or care because it probably isn't the immediate problem they are solving, and if they get to the problem later they likely can't remember who or what it is was. For everyone that doesn't care about that thing, it becomes instant spam :sad:. That by the way is what it is like when you post on Product Hunt.

## What are Objects in Programming?

Objects are a fundamental concept in programming, particularly in object-oriented programming (OOP). They represent real-world entities or concepts as software components with state (values of an object's attributes) and behavior (actions or methods). Objects are created from classes through instantiation and allow for modular, reusable code and more intuitive software design.
To know programming language you need to start from the beginning that is Object.

###INTRODUCTION

###A CLASS
A class is a blueprint for creating Object. A class  encapsulate data and funstions that manipulate data. Javascript classes are syntactic sugar over the  the prototypal inheritance ,in order word ES6 special functions. 
 
###HOW TO CREATE A CLASS
  To create a class you use the class keyword. Within the class, we create a constructor function, which define all the initial properties.

  A class is a template  for creating objects. All the properties in the constructor function will be automatically added to the new object.

 ###CONCLUSION
 Javascript class represent a major step forward in javascript object oreinted programming, javascript classes provide a much simpler and clearer syntax for creating objects and dealing with inheritance and also solve some problems that comes with using prototypes

A estrutura invisível: Descobrindo por que a lógica clássica é vital para programadores
Published: 2023-07-10 19:26:03

📚 Você sabia que a lógica clássica é uma ferramenta muito importante para os programadores? Neste artigo, vamos explorar o que é a lógica clássica, como ela pode ajudar os programadores e a importância de ter uma base estruturada nesse campo. Além disso, vou compartilhar alguns livros e autores sobre o assunto. Vamos lá! 🚀

## O que é lógica clássica?
A lógica clássica aristotélica é um sistema de pensamento desenvolvido pelo filósofo grego Aristóteles. Ele estabeleceu os princípios básicos da lógica clássica que ainda são amplamente utilizados hoje em dia. A lógica aristotélica se concentra em categorias, proposições e silogismos.
Nas categorias, Aristóteles agrupou objetos e conceitos em diferentes classes, como animais, plantas e substâncias. Ele também analisou a estrutura das proposições, que são afirmações sobre algo. Por exemplo, uma proposição pode ser "todos os gatos são animais".

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/oqbfo15o4iei0rwpqcmx.png)

Os silogismos são argumentos compostos por duas proposições chamadas premissas, seguidas de uma conclusão. Aristóteles desenvolveu regras para avaliar a validade dos silogismos. Por exemplo, se tivermos as premissas "todos os homens são mortais" e "Sócrates é homem", podemos concluir que "Sócrates é mortal".
A lógica clássica aristotélica fornece uma estrutura sólida para raciocinar de forma lógica e argumentar de maneira válida. Embora tenha sido desenvolvida há muito tempo, sua influência na lógica e na filosofia ainda é significativa nos dias de hoje.

## Como a lógica clássica pode ajudar os programadores?

Os programadores trabalham com códigos e algoritmos, que são sequências lógicas de instruções. A lógica clássica permite que eles entendam e desenvolvam essas sequências de maneira eficiente. Com ela, os programadores podem identificar erros em seus códigos, encontrar soluções para problemas complexos e criar programas mais robustos e confiáveis.

## A importância da base estruturada:

Ter uma base estruturada em lógica clássica é fundamental para os programadores. Essa base fornece uma compreensão sólida das estruturas lógicas subjacentes aos programas de computador. Com uma base sólida, os programadores podem construir algoritmos eficientes, evitar erros comuns e comunicar-se melhor com outros profissionais da área.

## Principais livros e autores sobre lógica clássica:

* "Introduction to Logic" por Irving M. Copi e Carl Cohen
* "A Concise Introduction to Logic" por Patrick J. Hurley
* "Logic and Philosophy: A Modern Introduction" por Alan Hausman e Howard Kahane
* "Organon" por Aristóteles
* "O trivium" por Miriam Joseph
* "Lógica Cosmologica" por Regis Jolivet
* "Lógica Menor" por Jacques Maritain

Getting Started with AWS Lambda: Building Serverless Functions
Tags: aws, computerscience, awsbigdata, beginners
Published: 2023-07-10 19:07:40

AWS Lambda is a convenient compute service offered by Amazon Web Services (AWS) that allows you to execute your code without the hassle of provisioning or managing servers.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/noeonxrnzidmug3a8xv4.jpg)

In this tutorial, we will guide you through the process of creating your initial serverless function using AWS Lambda.

### Prerequisites-

1. If you don't have an AWS account yet, you can easily create a free account at: https://aws.amazon.com/free/.

2. Once you've created your account, simply log in to the AWS Management Console at: https://console.aws.amazon.com/.

### Creating your first Lambda function

- Open the AWS Management Console and navigate to the Lambda service.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/zao0xs7k5s669mof07n3.png)


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/rp1nu6j7kojvn7sjuog9.png)

- Click on **Create Function** to initiate the creation of a new Lambda function.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/u27g71x4mjmxv18kev0o.png)

- Choose a blueprint that suits your specific use case. For instance, let's select the "hello world python" blueprint.



![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/7xajheb9scw442gfepxz.png)

#### Configure function details:

- Give your function a name, for example- MyFirstLambdaFunction. 
- Choose the runtime as **Python 3.8** (or any other runtime)


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/8sdexcoj2kgivks1arwc.png)

Leave the permissions settings as the default values for now.

- In the **Function code** section, you'll see the default code and you need to replace the code with the following snippet:

```
def lambda_handler(event, context):
    name = event['name']
    message = f"Hello, {name}!"
    return {
        'statusCode': 200,
        'body': message
    }

```

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/bq6fmtyakivhok6hwnh7.png)

- Configure the test event: Under the **Configure test events** dropdown, select **Hello-World** as the sample event template.

- Click on **Create** to create your Lambda function.

### Testing the Lambda function

- Once your function is created, you can test it by clicking on the **Test** button in the Lambda function console.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/11lces60iby4r2wip42p.png)

- Select the **HelloWorld** test event from the dropdown and click on **Test** again.

- You should see the output of your Lambda function in the console, which should be a JSON object containing the greeting message.

Mutable And Immutable Values in Javascript

In JavaScript there are two types of data types - primitive types and objects. Whenever you define a variable, the JavaScript engine allocates a memory to it. It stores all variable names on the Stack, while the values are either on the Stack or on the Heap.

```
let str = "hello"; 
// str (variable name) is stored on the Stack
// 'hello' (value) is stored on the Stack

let obj = { fname: "Vasil", lname: "Vasilev"} 
// obj (variable name) is stored on the Stack
// {...} the value is stored on the Heap
```

NB: The { fname: "Vasil", lname: "Vasilev"}  is merely a reference which points to the actual value stored on the Heap.

**Any data type value which is immutable is stored on a Stack data structure since it’s size is known during compilation phase.**

**Mutable data types such as Objects, Arrays are stored on a Heap data structure and a reference to the Object or array is stored on the stack data structure.**
