Get The Underlying OS on which the program is running in Java
Published: 2023-08-15 10:18:19

You may want to know the operating system on which your Java program is running because you want to

1. **Implement platform-specific behavior →** Let’s say you need to construct a file path in your program. But the ways in which file paths are constructed on Windows and Unix-based systems are different. Knowing the OS on which the program is running may help you implement a robust solution that works on different systems.
2. **Use a platform-specific library →** There are some libraries that work only on a particular OS. So, you want to know whether you can use one library in your program.
3. **Access System Properties →** There are some system properties that have different values on different operating systems. Such as the default temporary directory or the user home directory. Knowing the OS may help you access these values correctly.

If you have any of the above-mentioned use cases or any other use cases, but you want to know the OS on which your programming is running, you are in the right place.

Hi! I’m Gaurav Kumar, and you’re welcome to **"Re-Inventing the Wheel"**. Now, without further ado, let's see the code that will tell us about the OS on which it’s running.

Below is the code snippet to know the underlying OS on which it’s running.

```java
String os = System.getProperty("os.name");
System.out.println("OS: " + os);
```

**Note:** The string inside the **`getProperty()`** method is case-sensitive. Make sure that each letter used is in lowercase; otherwise, it returns `**null**`.

### Other ways to determine the OS

1. Using **`System.getenv`** method
    
    ```java
    String os = System.getenv("OS");
    System.out.println("OS: " + os);
    ```
    
    This code works fine on Windows. However, this code is not portable as the ***OS*** environment variable is not present by default on many other operating systems, such as **Linux and Mac OS**.
    
2. Using **`Runtime.exe`** method
    
    ```java
    Process p = Runtime.getRuntime().exec("uname -s");
    BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
    String os = reader.readLine();
    System.out.println("Operating system: " + os);
    ```
    
    This code executes the **`uname -s`** command, which returns the name of the operating system on Unix-based systems. However, this approach is not portable, as the **`uname`** command may not be available on all operating systems.
    

### Conclusion

The most reliable way to know the OS on which a program is running is to use **`System.getProperty`** method that works on all the operating systems.

At the end, I would like to take this opportunity to thank you for reading this article until the end.

Happy Coding 😀!

See you soon!
Turborepo and ts(2307) Error - Cannot find module 'abc' or its corresponding type declarations.ts(2307)
Published: 2023-08-15 10:02:46

When using Turborepo in VSCode, I have found that sometimes VScode starts throwing up 2307 errors. This is because it can't seem to see the modules installed at the root level inside a package. 

Turns out this is entirely just a weird Typescript issue, not Turborepo or VSCode

A guide to Git Aliases
Tags: git, beginners
Published: 2023-08-15 10:01:17

Typing long commands can get tiresome, this is where aliases can come in handy!

In this blog post I’ll share how you can set up aliases for your Git commands.  Using aliases allows you to set up shortcuts that will make your life easier.  There are two ways in which you can set up your aliases.

## Set up aliases using the Git config command
You can set up your aliases using a command within your command line tool. 

The format for the command is: 

```bash
git config --global alias.<alias-name> '<git-command>'
```

In practice that means if you want to type **git c** instead of typing **git checkout** the alias you would configure is: 

```bash
git config --global alias.c checkout
```

![Setting up a Git alias](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ypsgh4p59wrsqo78b1nd.png)


## Set up aliases using the .gitconfig file
Another approach is to make modifications to the .gitconfig file.  This is usually stored within your home directory, on my Windows machine it was stored under _C:\users\sarah\ _

Within this file create an alias section like below:
```bash
[alias]

# Shortcut for status
st = status

# Shortcut for checkout
co = checkout

# Shortcut for branch
b = branch

# Shortcut for help
h = help

# Shortcut for last commit
last = log -1 HEAD

# Shortcut to query log for altered files
l = log --stat

# Shortcut to query log and make it pretty
ld = log --graph --decorate --date=short
```

## Deleting a Git alias
If you want to remove an alias you can delete the configuration from the .gitconfig file or you can use the following command:

```bash
git config --global --unset alias.<alias-name>
```

![Deleting a Git alias](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/991xzbz5jxqske59i18n.png)

## Check all aliases in Git
If you want to check which aliases are currently set within your configuration you can use the command: 

```bash
git config --get-regexp '^alias\.'
```

## Using Git aliases

Now that the aliases are set up you can now use them when you are within your command line tool.  I can now use **git l** in lieu of **git log –stat**. 

> 💡 It’s important to remember, these aliases are only applicable to your local machine.

React Native cli v/s Expo
Tags: reactnative, expo, comparereactnativecliandexp
Published: 2023-08-15 09:34:35

hi techies,
All new techies who want to start with react native mostly get stuck to which platform they should choose to get head start on developing react native apps.


![Image source: techilaservices.com](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/iz2p6su451tkvk4mdeml.jpg)

From my work experience I found that

- Expo is the easiest way to get started with react native development.
- It provides an encapsulated environment which set the developer free from the Windows / macOS i.e. no worry about platform the output will be a QR which can be used by Android + iOS devices to track the project performance and progress
- But Expo give up when it comes to interact with native part of the device, lets say we want to execute some Java or iOS code or we need to access the native part of the device at that point Expo is of no use.
- Another issue is **Expo Go** App which is used to check / test the application work progress when the Expo Go is upgraded it make you sweat to execute the code on Expo Go or upgrade the old expo version code in new expo version

- So in short for small application where you do not have to deal with native support of device and only simple data movement from here to there then Expo is Good.

**Usual Case which might happen**
But lets say you started some project which later on or in next phases requires native support then in that case:

- You have to eject the project from expo
- This will return the bare react native cli project

**Now lets talk about React Native CLI**
I do not find anything wrong in react native cli.
Only part which I had read as cons of react native is that:

- it requires separate environment for windows and macOS to test and execute
- some of the packages when need to have `pod install`

Other than that I did not find anything which stops you to use React Native CLI

**Now What to choose**
I also started with Expo when I was new to React Native and it was good, but later when project started growing and more features were requested at that point of time I realized that native was better and then I started my code with React Native CLI which only make you work harder at the beginning but later you enjoy the project

So I would like to put my thought to start with React Native CLI always this will keep you happy 

Thanks guys for the reading🫡

Java Stack: Unveiling LIFO Magic
Tags: datastructures, algorithms, java, i
Published: 2023-08-15 09:28:07

A stack is a linear data structure that follows the principle of Last In First Out (LIFO). This means the last element inserted inside the stack is removed first.

_Concepts and Principles:_
Visualize a stack as a vertical arrangement of elements, where you can:

- Push:
 Add an element to the top of the stack.

- Pop:
 Remove an element from the top of the stack.

- IsEmpty:
 Check if the stack is empty.

- IsFull:
 Check if the stack is full.

- Peek:
 View the value of the top element without removal.

_Working of the Stack:_
In Java programming, we use a pointer called top to keep track of the top element. Upon initialization, top is set to -1 to indicate an empty stack. When an element is pushed, top is incremented, and for popping, it is decremented. These operations are carried out with checks to avoid overflow or underflow.

_Stack Implementation in Java:_
Below is a practical implementation of a stack in Java:

```

public class Stack {
    private int maxSize;
    private int[] stackArray;
    private int top;

    public Stack(int size) {
        maxSize = size;
        stackArray = new int[maxSize];
        top = -1;
    }

    public boolean isEmpty() {
        return top == -1;
    }

    public boolean isFull() {
        return top == maxSize - 1;
    }

    public void push(int value) {
        if (!isFull()) {
            stackArray[++top] = value;
            System.out.println("Pushed item: " + value);
        } else {
            System.out.println("Stack is full. Cannot push.");
        }
    }

    public int pop() {
        if (!isEmpty()) {
            return stackArray[top--];
        } else {
            System.out.println("Stack is empty. Cannot pop.");
            return -1; 
        }
    }

    public int peek() {
        if (!isEmpty()) {
            return stackArray[top];
        } else {
            System.out.println("Stack is empty. Cannot peek.");
            return -1; 
        }
    }
}
```
_Time Complexity:_
Stack operations using arrays have a constant time complexity (O(1)) for both push and pop, making them efficient and suitable for various applications.

_Applications:_
Stacks prove their versatility across various domains:

1. Expression Evaluation:
 Stacks assist compilers in evaluating expressions by converting them into postfix notation for efficient processing.

2. Function Calls:
 Method calls and recursion in programming languages often utilize stacks to manage execution contexts.

3. Browser History:
 Browsers utilize stacks to facilitate backward navigation through visited URLs.
¿Qué es SCRUM? Una introducción detallada
Tags: scrum, queesscrum
Published: 2023-08-15 09:26:57

En el dinámico panorama actual, donde la rapidez y la adaptabilidad son cruciales para el éxito, las empresas están adoptando enfoques más ágiles para gestionar proyectos y entregar valor. Uno de estos enfoques es SCRUM. Aunque se originó en el mundo del desarrollo de software, su versatilidad lo ha hecho popular en una variedad de industrias. Vamos a sumergirnos profundamente en el mundo de SCRUM.

## 1. Historia de SCRUM

SCRUM no es una invención reciente. De hecho, se inspiró en un artículo de 1986 escrito por Hirotaka Takeuchi y Ikujiro Nonaka en la "Harvard Business Review". En este artículo, los autores comparaban el desarrollo de proyectos exitosos con los scrums en el rugby, donde un equipo trabaja hacia un objetivo común en lugar de pasar el balón de un jugador a otro.

## 2. Principios y Valores de SCRUM

Más allá de las características y eventos, SCRUM se basa en valores fundamentales: compromiso, coraje, enfoque, apertura y respeto. Estos valores garantizan que todos los miembros del equipo se mantengan alineados y se comuniquen efectivamente.

## 3. Artefactos de SCRUM

Además de los roles y ceremonias, SCRUM se compone de varios artefactos:

**Product Backlog**: Es una lista priorizada de características, funcionalidades y requisitos del producto. Está en constante evolución y es gestionada por el Product Owner.

**Sprint Backlog**: Se extrae del Product Backlog y contiene las tareas seleccionadas para el sprint actual. Es una guía para el equipo de desarrollo sobre lo que necesita hacerse durante el sprint.

**Incremento**: Es el resultado del sprint, un producto usable y potencialmente desplegable.

## 4. Beneficios adicionales de SCRUM

**Eficiencia mejorada**: Al eliminar tareas innecesarias y enfocarse en las prioridades, los equipos pueden producir más en menos tiempo.

**Satisfacción del cliente**: Al entregar regularmente y recopilar retroalimentación, se garantiza que el producto final se alinee con las expectativas y necesidades del cliente.

**Desarrollo profesional**: SCRUM también ofrece oportunidades para el crecimiento profesional. Los miembros del equipo aprenden a trabajar en ambientes colaborativos, a tomar decisiones rápidamente y a adaptarse a cambios inesperados.

## 5. Desafíos de SCRUM

Como cualquier metodología, SCRUM no está exento de desafíos. Requiere un cambio cultural, un compromiso total de todos los participantes y una formación adecuada. Es esencial comprender que simplemente seguir los pasos de SCRUM sin adoptar su filosofía puede no producir los resultados deseados.

## Conclusión ampliada

SCRUM es mucho más que una simple lista de reglas o procedimientos; es una forma de pensar y actuar en el mundo profesional. Es un compromiso con la excelencia, la adaptabilidad y la colaboración. Con la comprensión y la aplicación adecuadas, SCRUM puede ser una herramienta poderosa para cualquier organización que busque mantenerse relevante y eficiente en un mundo que cambia rápidamente.

JavaScript Equality Operators: Demystifying == vs. === for Precise Comparisons
Tags: javascript, beginners, webdev, tutorial
Published: 2023-08-15 08:23:57


When it comes to comparisons in `JavaScript`, the choice between the `==` (loose equality) and `===` (strict equality) operators can have a significant impact on your code's behavior. Let's explore the key differences with practical code examples.

`Loose Equality (==):`

The `==` operator performs type coercion, converting operands to the same type before comparison:

![javascript](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/smro6h3f6p74r4m5q8rm.png)
`Strict Equality (===)`:

The `===` operator checks both value and type, without type coercion:

![javascript](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/c2q294x3tc3vrurhzzb4.png)

## When to Use Each:

1. `Use === (Strict Equality) By Default:`

For most scenarios, strict equality is recommended. It prevents unexpected type conversions:


![javascript](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/7ixbrxa1j5l3smq46sin.png)

2. `Use == (Loose Equality) When Necessary`:

Use loose equality when you specifically want type coercion, like checking for null or undefined:

![javascript](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/3w5bovwr5vvvkg1y4b0b.png)

## Best Practices:

1. `Consistency`: Prioritize `===` for consistency and predictability.
2. `Explicit Type Checking`: Use `===` for explicit type checking:


![javascript](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/n9cdmfbuv2ghx2nk4lmb.png)

## Conclusion:

While both `==` and `=== `have their use cases, the `===` (strict equality) operator is generally safer due to its explicit type checking and avoidance of implicit conversions.
