- [Wrapper Types](#wrapper-types)
   * [system diagram](#system-diagram)

{%- # TOC end -%}

## Basic Data Structure
There are eight major data types in Java, which can be divided into numerical, character, and boolean types.

- Numerical Types

| Data Type   | Size | Ranges |
| ---------- | ---- | -------- |
| byte | 8 bit  | -128 ~ 127 |
| short| 16 bit | -2^15 ~ 2^15 - 1 |
| int  | 32 bit | -2^31 ~ 2^31 - 1 |
| long | 64 bit | -2^63 ~ 2^63 - 1 |
| float | 32 bit | single precision floating point type, such as 2.0f |
| double | 64 bit | higher precision floating point type, such as 2.0 |

- Character Types

| Data Type   | Size | Ranges |
| ---------- | ---- | -------- |
| char | 16 bit  | Used to represent Unicode characters, 1 character = 2 bytes |

- Boolean Types

| Data Type   | Size | Ranges |
| ---------- | ---- | -------- |
| boolean | logical value | true && false |

---

## Wrapper Types
In Java, each primitive data type has a corresponding wrapper class. Assignment and conversion between the primitive types and their corresponding wrapper classes are achieved through automatic boxing and unboxing.

| Primitive Data Types | Wrapper Classes |
| -------------------- | --------------- |
| boolean              | Boolean         |
| char                 | Character       |
| byte                 | Byte            |
| short                | Short           |
| int                  | Integer         |
| long                 | Long            |
| float                | Float           |
| double               | Double          |

1. Automatic Boxing refers to automatically converting a primitive value into its corresponding object wrapper.

2. Unboxing is the reverse process where an object wrapper's value is converted back to its corresponding primitive type.

Mount EBS Volume with EC2 Linux Instance
Tags: aws, linux, ec2, ebs
Published: 2024-01-25 10:44:15

Amazon Elastic Block Store (EBS) is an easy-to-use, scalable, high-performance block-storage service designed to work with EC2 instances. Unlike the instance store volume that comes with an EC2 instance, which is ephemeral and gets deleted when the instance is terminated, EBS volumes are independent of the instance and persist even after the instance is terminated. This means that any data written to the EBS volume will be preserved and can be accessed when the instance is restarted or launched again. There are several reasons why you might want to attach a separate EBS volume to an EC2 instance. Some of them are,

**1. Data Persistence**
**2. Scalability and flexibility**
**3. Performance**

In this blog post, we will learn about mounting an EBS instance in a Ubuntu Linux machine.

After attaching an EBS volume with a running EC2 instance, you can check it using the list block command 

```
> lsblk
```

![Image](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/em0fgwb62sawczvwmgx3.png)

After that create a mount point in the `/mnt` folder.

```
> sudo mkdir -p /mnt/db
```

`/mnt/db` folder will be used for mounting the volume. So let's create the `ext4` file system in the newly attached volume `xvdf`

```
> sudo mkfs -t ext4 /dev/xvdf
```

![Image](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ayst4fob8am7aivgjecz.png)

Now our file system is ready in the volume `/dev/xvdf`. For mounting it with `/mnt/db` we just need to use the mount command.

```
> sudo mount /dev/xvdf /mnt/db
```

Congratulations you have successfully mounted the volume and it's ready to use. For checking it you can use `lsblk` command.


![Image](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/djdaswmz3lyir3dkvg9i.png)

For initializing the attached volume after an instance reboot/restart we can use the Linux file systems table `/etc/fstab`. Open the file `/etc/fstab` using `nano` and add the below-mentioned line at the end of the file.

```
/dev/xvdf   /mnt/db   ext4   defaults,nofail   0   2
```

Save & Close the file. Enjoy!

[20 Days of DynamoDB] Day 13 - Using the DynamoDB expression package to build Condition expressions
Tags: dynamodb, serverless, database, cloud
Published: 2024-01-25 10:32:50

*Posted: 25/Jan/2024*

Thanks to the `expression` package in the AWS Go SDK for DynamoDB, you can programmatically build Condition expressions and use them with write operations. Here is an example with the `DeleteItem` API:

```go
	conditionExpressionBuilder := expression.Name("inactive_days").GreaterThanEqual(expression.Value(20))
	conditionExpression, _ := expression.NewBuilder().WithCondition(conditionExpressionBuilder).Build()

	_, err := client.DeleteItem(context.Background(), &dynamodb.DeleteItemInput{
		TableName: aws.String(tableName),
		Key: map[string]types.AttributeValue{
			"email": &types.AttributeValueMemberS{Value: email},
		},
		ConditionExpression:       conditionExpression.Condition(),
		ExpressionAttributeNames:  conditionExpression.Names(),
		ExpressionAttributeValues: conditionExpression.Values(),
	})
```

Primeros errores con React + Vite
Tags: react, vite, swc, spanish
Published: 2024-01-25 10:11:30

## La Problemática
Esta mañana, retomé mis ejercicios con React como de costumbre. Al ejecutar VScode y realizar un git pull para traer los cambios de ayer, me encontré con una sorpresa desagradable.

`[vite] Internal server error: Bindings not found. Plugin: vite:react-swc
`
Tanto en la terminal como en la web, se lanzó un error relacionado con el compilador SWC.

## No te pongas aerodinámico conmigo
Después de entrar en pánico durante unos segundos, lo primero que se me ocurrió fue repasar el commit del día anterior. Sin embargo, para mi sorpresa, 😅 solo había cambios de estilo en archivos CSS 🤔, por lo que descartamos esa opción.

## Reinicia, que eso suele funcionar
El siguiente paso fue ejecutar npm i para actualizar las dependencias, pero solo conseguí que npm me "sugiriera encarecidamente que arregle problemas de seguridad".

## Auditfix, pero seguimos igual
Después de solucionar los problemas de seguridad, continuamos con el problema. 🤔 ¿Y si vuelvo a instalar todo el proyecto? No sonaba mal, así que manos a la obra.

## Vuelta a empezar
Decidí eliminar la carpeta `node_modules` y el archivo `package-lock.json` del proyecto para realizar una instalación "limpia" de las dependencias. Ejecutamos el proyecto y 🎉¡Funciona!🎉.

Desconozco cuál sería el motivo por el que SWC decidiera dejar de funcionar repentinamente, pero al menos ya tenemos una manera rápida de solucionar el problema.

¿Te ha pasado alguna vez lo mismo?
JWT in RTOS
Tags: iot, rtos, tutorial, c
Published: 2024-01-25 10:02:23

> JWT(JSON Web Token) 在IOT常被使用的Token協定。因為其具有方便製作以及高安全性被廣泛使用各種裝置認證。這篇文章主旨是在RTOS mbed環境中，使用open ssl從KEY pair的生成到使用KEY簽屬JWT，之後再使用Public key認證JWT token

##JWT的組成
JWT可以分為三個部分組成，分別為:**header.payload.signature**

##Mbed JWT tutorial
### zephyer environment
- open one thread to run jwt ， this article only foucus on how zephyer jwt used. 
### 1. Open ssl - Key pair generate
create key use mbedtls header

```C
#include <mbedtls/pk.h>
#include "mbedtls/entropy.h"
#include <mbedtls/rsa.h>
#include <mbedtls/sha256.h>
```
- Gen private key
- Gen key pair

```C
#use for random seed
static int csprng_wrapper(void *ctx, unsigned char *dest, size_t size)
{
	ARG_UNUSED(ctx);
	return sys_csrand_get((void *)dest, size);
}

void create_rsa_keys(mbedtls_pk_context *private_key) 
{
    mbedtls_entropy_context entropy;
    mbedtls_ctr_drbg_context ctr_drbg;
    mbedtls_entropy_init(&entropy); #進行初始化
    mbedtls_ctr_drbg_init(&ctr_drbg); #進行亂數的初始化
    const char *pers = "test pers for test" # 設置pers
    const char *msg = "test msg for test" #設置msg
    
    int ret = mbedtls_ctr_drbg_seed(&ctr_drbg, csprng_wrapper, NULL ,(const unsigned char *)pers, strlen(pers));#封裝生成key 的seed
    ret = mbedtls_pk_setup(private_key, mbedtls_pk_info_from_type(MBEDTLS_PK_RSA));#輸入的位置初始化為儲存private key的空間
   mbedtls_rsa_gen_key(mbedtls_pk_rsa(*private_key), csprng_wrapper, NULL, 2048, 65537); #產生private key後儲存
   printf("\r\nKey generation %s\r\n", ret == 0 ? "successful" : "failed");
   ret = mbedtls_rsa_check_privkey(mbedtls_pk_rsa(*private_key)); #check private key 是否合法
   printf("\r\n check private key sucessfully %s\r\n", ret == 0 ? "successful" : "failed");
   mbedtls_ctr_drbg_free(&ctr_drbg); #釋放空間
   mbedtls_entropy_free(&entropy); #釋放空間

 }  
   
```
因為public key可以快速地從private key中取得。在mbedtls中有兩組函數

```C
mbedtls_pk_parse_key(&pri_key, private_pem_buf, strlen(private_pem_buf) + 1, NULL, 0, csprng_wrapper, NULL);
#此函數的pk不代表private key，因此函數將同時撈出private key and public key儲存到第一個你指定的空間中，private_pem_buf則是你存放的private key

mbedtls_pk_parse_public_key(); # 而此函數直接提取public key
```




### 2. Mbed JWT - Create JWT token

- Use mbed JWT lib
- Use private key sign Token

### 3. Token verify 

- use Public key verify

Published: 2024-01-25 09:53:43

History of Web 3.0: Web 1.0

Web 1.0 consisted of all static websites created using HTML, CSS, and JavaScript. There weren't many web applications on the internet, and there was minimal interaction.

During this period, we had messengers like MSN and AOL chat rooms. Overall, the user experience was not as advanced as it is in today's network. Additionally, we couldn't stream music and videos at that time.

Web 2.0: The Rise of Interaction

The introduction of Web 2.0 marked a significant shift. Websites became dynamic, allowing user-generated content and interaction. Social media platforms, blogs, and forums emerged, bringing people together on the internet. Services like Facebook, YouTube, and Wikipedia exemplify the Web 2.0 era.

Web 3.0: Decentralization and Blockchain

Web 3.0 represents the next phase in the evolution of the internet. It emphasizes decentralization, increased user control over data, and the integration of blockchain technology. Blockchain, the underlying technology of cryptocurrencies like Bitcoin and Ethereum, brings transparency, security, and trust to online interactions.
