Published: 2023-04-27 21:53:20

Muitas vezes desejamos mostrar uma mensagem de alerta na tela de um usuário e podemos usar diversos meios como um Text ou até um Alert para aviso. Entretanto o React tem a sua disponibilidade os Toast de notificação. Neste artigo iremos criar Toasts. Ele fornece dois tipos de toasts: sucesso e erro, que são personalizáveis ​​por meio do objeto ToastConfig fornecido.

**Instalação da biblioteca Toast -**

Para usar este componente, instale-o como um pacote npm:

```
npm install --save react-native-toast-message
yarn add react-native-toast-message
```

**Utilizando o Toast-**

Importe o Provider componente do pacote e envolva-o em seu componente principal:

```
import Toast from "react-native-toast-message";

const App = () => {
  return (
    <View>
      {/* Your main component */}
      <Toast.Provider />
    </View>
  );
};
```

Isso cria um provedor toast que pode ser usado para mostrar mensagens toast. Para mostrar uma mensagem toast, basta chamar o método showSuccess ou showError do Toast objeto:

```
import Toast from "react-native-toast-message";

const ExampleComponent = () => {
  const handleButtonClick = () => {
    Toast.showSuccess("Success message");
    Toast.showError("Error message");
  };

  return (
    <View>
      <Button title="Show Toast" onPress={handleButtonClick} />
    </View>
  );
};
```
Por padrão, o componente será exibido na parte inferior da tela, acima do teclado (se estiver visível). Você pode personalizar a aparência do brinde passando um ToastConfigobjeto para o componente Provider:

```
import Toast from "react-native-toast-message";

const config = {
  successStyle: {
    backgroundColor: "#00FF00",
  },
  errorStyle: {
    backgroundColor: "#FF0000",
  },
  textStyle: {
    color: "#FFFFFF",
  },
};

const App = () => {
  return (
    <View>
      {/* Your main component */}
      <Toast.Provider config={config} />
    </View>
  );
};
```
Com isso, conseguimos ver o quão fácil é utilizar o Toast. Espero que este artigo tenha o ajudado a criar mensagens de notificação para sua aplicação mobile feita em React Native. Obrigado por ler até aqui.
Control Structures
Tags: python, beginners, programming, tutorial
Published: 2023-04-27 21:12:20

In Python, control structures are essential constructs that allow programmers to control the flow of execution of a program. Control structures include if-else statements, loops, and functions. In this blog post, we will explore each of these control structures in detail, including their syntax, properties, and usage.
## If-Else Statements
If-else statements are used to make decisions in a program. They evaluate a condition and execute a block of code if the condition is true, or another block of code if the condition is false.

For example, the following code snippet uses an if-else statement to check if a number is even or odd:

```
num = 5

if num % 2 == 0:
    print(num, "is even")
else:
    print(num, "is odd")
```

Output:

```
5 is odd
```
## Loops
Loops are used to execute a block of code repeatedly. Python supports two types of loops: for loops and while loops.
### For Loops
For loops are used to iterate over a sequence of elements, such as a list, tuple, or dictionary. The loop variable takes on each element of the sequence in turn, and the block of code inside the loop is executed for each element.

For example, the following code snippet uses a for loop to iterate over a list of numbers and print each number:

```
numbers = [1, 2, 3, 4, 5]

for num in numbers:
    print(num)
```

Output:

```
1
2
3
4
5
```
### While Loops
While loops are used to execute a block of code repeatedly as long as a condition is true. The condition is evaluated at the beginning of each iteration, and the block of code inside the loop is executed only if the condition is true.

For example, the following code snippet uses a while loop to print the first 5 numbers:

```
num = 1

while num <= 5:
    print(num)
    num += 1
```

Output:

```
1
2
3
4
5
```
## Functions
Functions are used to encapsulate a block of code that performs a specific task. Functions can accept input arguments, perform computations, and return output values.

For example, the following code snippet defines a function that takes two arguments and returns their sum:

```
def add_numbers(x, y):
    return x + y

result = add_numbers(2, 3)
print(result)
```

Output:

```
5
```
Control structures are fundamental constructs that every Python programmer needs to be familiar with. If-else statements are used to make decisions, while loops and for loops are used to execute code repeatedly, and functions are used to encapsulate and reuse code. By mastering these control structures, you can control the flow of execution of your program and write efficient and effective code.
Data Types and Structures
Tags: python, programming, tutorial, beginners
Published: 2023-04-27 21:08:50

In Python, data types and structures are fundamental concepts that every programmer needs to be familiar with. Python provides various built-in data structures, such as lists, dictionaries, sets, and tuples, which can be used to represent and manipulate data efficiently. In this blog post, we will explore each of these data types and structures in detail, including their syntax, properties, and usage.
## Lists
A list is a mutable sequence data type that can hold any number of elements of different types. Lists are created by enclosing a comma-separated sequence of elements in square brackets [].

For example, the following code snippet creates a list of integers and prints its contents:

```
my_list = [1, 2, 3, 4, 5]
print(my_list)
```

Output:

```
[1, 2, 3, 4, 5]
```

Lists support various operations such as appending, inserting, removing, and slicing. For example, we can append a new element to the end of the list using the `append()` method:

```
my_list = [1, 2, 3, 4, 5]
my_list.append(6)
print(my_list)
```

Output:

```
[1, 2, 3, 4, 5, 6]
```
## Dictionaries
A dictionary is an unordered collection of key-value pairs, where each key is associated with a value. Dictionaries are created by enclosing a comma-separated sequence of key-value pairs in curly braces {}.

For example, the following code snippet creates a dictionary of person names and their ages:

```
my_dict = {'Alice': 25, 'Bob': 30, 'Charlie': 35}
print(my_dict)
```

Output:

```
{'Alice': 25, 'Bob': 30, 'Charlie': 35}
```

Dictionaries support various operations such as adding, deleting, and modifying key-value pairs. For example, we can add a new key-value pair to the dictionary using the square bracket notation:

```
my_dict = {'Alice': 25, 'Bob': 30, 'Charlie': 35}
my_dict['David'] = 40
print(my_dict)
```

Output:

```
{'Alice': 25, 'Bob': 30, 'Charlie': 35, 'David': 40}
```
## Sets
A set is an unordered collection of unique elements. Sets are created by enclosing a comma-separated sequence of elements in curly braces {}.

For example, the following code snippet creates a set of integers:

```
my_set = {1, 2, 3, 4, 5}
print(my_set)
```

Output:

```
{1, 2, 3, 4, 5}
```

Sets support various operations such as adding, removing, and manipulating elements. For example, we can add a new element to the set using the `add()` method:

```
my_set = {1, 2, 3, 4, 5}
my_set.add(6)
print(my_set)
```

Output:

```
{1, 2, 3, 4, 5, 6}
```
## Tuples
A tuple is an immutable sequence data type that can hold any number of elements of different types. Tuples are created by enclosing a comma-separated sequence of elements in parentheses ().

For example, the following code snippet creates a tuple of integers and prints its contents:

```
my_tuple = (1, 2, 3, 4, 5)
print(my_tuple)
```

Output:

```
(1, 2, 3, 4, 5)

Used Hospital Beds For Sale
Published: 2023-04-27 20:10:09

As healthcare costs continue to rise, hospitals and medical facilities are always looking for ways to cut expenses. One solution that has gained popularity in recent years is the purchase of [used hospital beds](https://landolov.com/product-category/used-hospital-beds/). These beds are typically sold by hospitals that are upgrading their equipment or closing down.

But what exactly are used hospital beds and why would anyone want to purchase them?

Used hospital beds are exactly what they sound like - beds that have been previously used in a medical facility. They are typically sold at a lower price than new beds and can be a cost-effective option for smaller medical facilities, long-term care facilities, and even individuals in need of home care.

While the idea of purchasing a used hospital bed may seem unappealing to some, it’s important to note that these beds are thoroughly cleaned, sanitized, and refurbished before being resold. In fact, many used hospital beds are in excellent condition and are just as functional as new beds.

One of the main advantages of purchasing a used hospital bed is the cost savings. New hospital beds can cost thousands of dollars, but used beds can be purchased for a fraction of the cost. This can be especially beneficial for smaller medical facilities or individuals who may not have the budget for a brand new bed.

Used hospital beds can also be a more sustainable option. By purchasing a used bed, you are preventing it from ending up in a landfill and reducing the demand for new beds to be manufactured.

It’s important to note that when purchasing a used hospital bed, you should do your research and make sure you are working with a reputable seller. Look for a seller who thoroughly inspects and refurbishes their beds before selling them and who offers a warranty or return policy.

Overall, purchasing a used hospital bed can be a cost-effective and sustainable solution for medical facilities and individuals in need of home care from [Landolov](https://landolov.com/). By choosing to purchase used equipment, you can save money while also doing your part to reduce waste and promote sustainability.

Getting started with Apache AgeDB: A Beginner's Guide
Published: 2023-04-27 18:39:53

If you're looking to work with complex, highly interconnected data, then Apache AgeDB may be just what you need. This open-source graph database is designed to handle data with complex relationships, making it ideal for use cases such as social networks, recommendation engines, and fraud detection systems. In this blog, we'll walk you through the process of getting started with Apache AgeDB, from installation to running your first queries.

### Step 1: Installing Apache AgeDB
The first step to getting started with Apache AgeDB is to install it. Apache AgeDB is built as an extension to PostgreSQL, so you'll need to have PostgreSQL installed on your system first. 

If you don't have PostgreSQL installed, you can download it from the official PostgreSQL website.

Once you have PostgreSQL installed, you can install Apache AgeDB by following these steps:
1. Download the latest version of Apache AgeDB from the official Apache AgeDB website.

2. Extract the downloaded archive to a directory of your choice.

3. Run the following command to install Apache AgeDB:

```
make install 
```

4. Finally, restart PostgreSQL to load the newly installed extension.

### Step 2: Creating a database
With Apache AgeDB installed, the next step is to create a database. To create a new database in PostgreSQL, you can use the createdb command. For example, to create a database named mydatabase, you can run the following command:

```
createdb mydatabase 
```

Once you have created a database, you can create a graph in Apache AgeDB by running the following SQL command:

```
CREATE GRAPH mygraph; 
```
This will create a new graph named mygraph in your database.

### Step 3: Creating nodes and edges
Now that you have a graph, you can start adding nodes and edges to it. To add a node to a graph, you can use the following SQL command:

```
INSERT INTO mygraph.vertices VALUES (1, 'Alice'); 
```
This will create a new node with an ID of 1 and a label of "Alice" in the graph.

To add an edge between two nodes, you can use the following SQL command:

```
INSERT INTO mygraph.edges VALUES (1, 2, 'knows'); 
```
This will create a new edge with a label of "knows" between the nodes with IDs 1 and 2.

### Step 4: Running queries
Now that you have some data in your graph, you can start running queries to retrieve and manipulate it. Apache AgeDB uses the Cypher query language, which is designed specifically for graph databases. Here's an example of a simple Cypher query that retrieves all nodes in the graph:

```
MATCH (n) RETURN n; 
```

This query will return a list of all nodes in the graph, along with their properties.

### Conclusion
Getting started with Apache AgeDB may seem daunting at first, but with these basic steps, you should be able to get up and running in no time. From here, you can start exploring more advanced features of Apache AgeDB, such as indexing and traversal queries, and begin to unlock the full potential of your graph data.
