Little PRs make the mighty refactor
Published: 2024-06-27 04:03:30

## Need of the hour
Refactoring is a crucial part of software development. It involves altering the structure of the code without changing its functionality. However, it's a process that can be fraught with risk if not carefully and thoroughly reviewed. This risk becomes exacerbated when automated tests, which serve as a safety net, ensuring that the code being modified still functions as expected, are not present.

## Common problems

A common pitfall that developers often fall into when undertaking a refactor is the temptation to tackle everything at once. This usually results in a large and unwieldy pull request, which can be quite daunting for anyone tasked with reviewing it. The larger the pull request, the greater the risk of crucial details being missed, errors being overlooked, and the process becoming excessively time-consuming.

## Strategize

A far more effective and efficient strategy is to break down the refactor into smaller, more manageable parts or segments. This approach not only simplifies the task at hand but also makes the review process a lot easier and far less prone to error. It's a simple matter of comparison; reviewing 10 files is significantly simpler and less time-consuming than reviewing 100 files. The smaller the task, the more attention to detail can be provided, leading to a more thorough and accurate review process.

## The real life matrix

Let's delve into the practicalities of the refactoring process. Suppose you're working on a project and you create a branch off from your `main` branch, naming it `refactor-1`. However, `refactor-1` isn't merged yet. But you have more work to do on the refactor, so what do you do? You create another branch off from `refactor-1`, naming it `refactor-2`, and you continue working there.

## Sailing on 2 ships

But what happens if you need to make changes to `refactor-1`? Perhaps there was an oversight in the initial refactor, or maybe new information has come to light that requires alterations to the code in `refactor-1`. In this situation, you would make the necessary changes to `refactor-1`, and then rebase `refactor-2` with `refactor-1`. This process ensures that `refactor-2` remains up-to-date with any changes made in `refactor-1`, maintaining code integrity and consistency throughout the refactor.

## The Essence

In conclusion, when undertaking a refactor, it's paramount to remember the importance of thorough review, the advantages of breaking down the task into smaller parts, and the necessity of maintaining code consistency when branching and rebasing. These practices lead to a smoother, more efficient refactoring process, minimizing risk and maximizing code quality.

了解用户中心与单点登录 （SSO）
Tags: webdev, javascript, python, ai
Published: 2024-06-27 03:35:03

在当今互联的数字环境中，有效管理用户身份对于安全性和用户体验都至关重要。该领域的两个基本组件是用户中心和单点登录 （SSO） 系统。虽然两者都有助于用户身份验证和访问控制，但它们具有不同的目的并提供独特的优势。

用户中心：集中式身份管理

用户中心，通常称为用户管理系统 （UMS），充当集中式存储库，用于在特定应用程序或平台生态系统中存储和管理用户身份、配置文件和访问权限。它的主要功能围绕着维护一个全面的用户信息数据库，其中包括个人详细信息、偏好、角色和权限。

用户中心的主要特点：

集中式身份存储：所有用户数据都存储在一个地方，确保一致性和易于管理。
精细访问控制：管理员可以定义和强制实施针对不同用户角色或组定制的访问权限。
用户配置文件管理：详细的用户配置文件允许个性化的用户体验和有针对性的通信。
集成能力：通常与平台内的其他系统集成，促进各种服务的无缝功能。
用户中心对于需要强大身份管理功能的平台至关重要，可确保管理员完全控制谁访问系统内的内容。它们为用户身份验证和授权提供了一种结构化的方法，增强了安全性和对数据保护法规的遵守。

单点登录 （SSO）：简化访问

相比之下，单点登录 （SSO） 简化了跨多个相关但独立的系统或应用程序的用户身份验证过程。SSO 不要求用户单独登录每个系统，而是允许用户进行一次身份验证并访问所有连接的系统，而无需重新输入凭据。这通过减少登录提示的数量来简化用户体验，并通过集中身份验证来增强安全性。


单点登录 （SSO） 的主要特点：

统一认证：用户只需登录一次，即可访问多个系统或应用程序。
增强的用户便利性：减少密码疲劳，提高工作效率。
集中控制：管理员可以集中管理用户访问权限，必要时只需一次操作即可撤销所有系统的访问权限。
安全优势：最大限度地降低密码相关漏洞的风险，并增强对安全策略的合规性。
SSO 在用户定期与多个互连系统（如企业应用程序或协作平台）交互的环境中特别有用。它提高了效率和用户满意度，同时保持了严格的安全措施。

选择正确的解决方案

在用户中心和单点登录 （SSO） 之间做出决定时，组织应考虑其在身份管理、访问控制要求和用户体验目标方面的特定需求：

用户中心非常适合需要详细的用户管理功能、严格的访问控制和个性化用户体验的平台。
SSO 适用于需要跨多个系统无缝访问用户的环境，在保持强大安全协议的同时提高便利性和生产力。
总之，虽然用户中心和单点登录系统在管理数字身份方面都发挥着关键作用，但它们的功能迎合了身份管理和用户访问控制的不同方面。了解这些区别使组织能够实施符合其运营需求和战略目标的最合适的解决方案。

用户中心的定义和作用
用户中心通常指的是一个专门负责管理用户信息和授权的应用程序。在大型应用系统中，用户中心将用户的登录认证、权限控制、个人信息管理等功能独立出来，形成一个单独的模块或服务。这样做的好处是可以集中管理用户信息，提高系统的安全性和稳定性，同时也便于维护和扩展。

用户中心的设计原则
用户中心的设计原则通常遵循以用户为中心的设计理念，即通过深入了解用户的需求和使用习惯，来设计符合用户期望的功能和服务。这种设计方法强调用户的参与和反馈，确保产品能够满足用户的实际需求，提升用户体验


用户中心功能
用户服务中心：负责管理用户的基本信息，如用户名、密码、电子邮件地址、手机号码等，并提供用户注册、登录、密码找回、修改个人信息等服务。

账号服务中心：涉及账号的创建、管理、注销以及状态控制等功能，如账号锁定、账号封锁等。

BAC服务中心：基于角色的访问控制（Role-Based Access Control），用于管理用户的权限，如访问控制、操作控制等

结论
用户中心在企业中的应用为企业带来了诸多价值，随着数字化时代的到来，客户体验已成为企业竞争的关键要素之一。因此，建立用户中心、优化客户体验已成为企业数字化转型的重要方向之一。在未来，随着技术的不断发展和创新，相信用户中心将在企业中发挥更加重要的作用，为企业带来更多的价值。

Lattice Generation using GPU computing in realtime

Published: 2024-06-27 02:53:12

Here I am sharing a opensource software through which possibility to create lattice structure which can change shape and size spatially that too in real time (almost) . Even though heavy computation are happening in the background , with the help of GPU computing it is achieved with element wise computation executing parallely. This helps in avoiding the storage creation of very big Matrices. Without the memory problem(huge RAM memory), this sofware package increases the feasibility for generating spatially variant lattice for real world problems.

The main dependencies required for this software to run are CUDA, Vulkan and GLFW.

Cuda facilitate parallel computation,

Vulkan handles faster visualisation ,

GLFW handles the window management.

The possibilities of this software is demonstrated with 6 different examples in the following picture

Normal  - no change in the orientation of lattice

Bend  - Bending the lattice progressively from 0 to 90 degree

Round - 360 degree rotation of lattice

Uniform - No change in size

Varying - Changes in size

## _**Normal and Uniform**_

Why are cookies ";" seperated
Tags: javascript, systemdesignwithzeeshanali
Published: 2024-06-27 02:51:15

Hi Guys,

This article is straightforward and adheres to standard practices.

In a recent interview, I was asked why cookies are separated by a semicolon (`;`) and not by any other unique character.

The answer is:

Important reason for using `;` as a separator in cookies is to comply with the syntax rules defined by the **HTTP protocol specifications**. These rules ensure that cookies can be reliably parsed and understood by different web browsers and servers. Here are additional technical reasons:

1. **Backward Compatibility**: Early implementations of cookies in web browsers used `;` as a separator, and maintaining this convention ensures backward compatibility with older browsers and web applications. Changing the separator could break existing systems.

2. **Simplicity in Parsing**: Using a single character as a separator simplifies the parsing logic for cookies. Web browsers and servers can use simple string-splitting functions to break down the cookie string into its individual components. This reduces the complexity of the code and helps avoid errors.

3. **RFC Compliance**: The use of `;` as a separator is specified in RFC 6265, which outlines the standards for HTTP cookies. Adhering to this standard ensures interoperability between different web technologies.

### RFC 6265 Excerpt

RFC 6265 explicitly defines the use of `;` as a separator in cookie headers:

```
cookie-header = "Cookie:" OWS cookie-string OWS
cookie-string = cookie-pair *( ";" SP cookie-pair )
cookie-pair = cookie-name "=" cookie-value
```

This excerpt from the specification shows that each `cookie-pair` (a name-value pair) is separated by a `;` followed by optional whitespace.

### Example in Context

Here’s how a cookie header looks in an HTTP response, adhering to the standard:

```
Set-Cookie: theme=light; Expires=Wed, 21 Oct 2024 07:28:00 GMT; Path=/; Secure; HttpOnly
```

In this context, the `;` ensures that each attribute of the cookie is clearly delineated, which is crucial for proper parsing and handling by the browser.

By using `;` as the separator, web technologies ensure consistent and reliable handling of cookies across different platforms and implementations. This consistency is vital for the correct operation of web applications that depend on cookies for session management, user preferences, and other functions.

Parsing the Interwebs
Tags: ruby, scraping, beginners, nokogiri
Published: 2020-09-25 20:51:04

My first cli project I created from scratch used Nokogiri. I found that using the The Bastards Book of Ruby was a great resource. I highly recommend checking out their website to refer to, if your looking to make a web scraper cli. Grabbing css selectors for the first time was not an easy task. The internet is deep and so are its selectors. You might be asking yourself how do you grab selectors? Using Nokogiri a ruby gem you parse the url creating nodes that you can then iterate over and use to present data to the end user. If you inspect the page and grab the css selector from the html you parsed, you can grab very specific data. I found that not every website could be scraped and that was my biggest setback. As a beginner in software development sometimes its better to take a step back, realizing that its not your fault your not getting the results you expect. The key here is to keep trying and don't give up. You will produce results with perseverance and patience.
The Lifecycle of a JavaScript File in the Browser: Request, Load, Execute1
Tags: javascript, execution, backstage, browser
Published: 2024-06-27 02:31:14

## Lifecycle of a JavaScript file in the browser: request, load, and execution

In this article, we'll walk through the life of a JavaScript file and see the full version of a file request, from its download, all the way to its execution. Understanding this method can help developers improve the performance of web pages and thus the user experience.

### 1. Request:
When the browser encounters a script tag in an HTML document, it sends an HTTP request to the server to get the JavaScript file specified in the src attribute. This request can be synchronous or asynchronous depending on how the tag is set up.

### 2. Load:
Once the request is sent, the browser starts loading the JavaScript file. During this phase, the browser can load multiple files in parallel to improve performance. However, the browser must be careful in the order in which files are loaded and executed to ensure that the page functions correctly.

### 3. Execute:
After the JavaScript file is fully loaded, the browser starts executing it. If the tag contains an async property, the file is executed immediately after it is uploaded. If it contains the defer property, the file is executed after the entire page is fully loaded and parsed.

1 - Request: The browser sends an HTTP request to the server to obtain a JavaScript file.
2 - Load: The browser starts loading the JavaScript file after receiving the request.
3 - Execute: The browser executes the JavaScript file after it has completed loading.

- Large or multiple JavaScript files can cause page loading delays. Therefore, it is important to use techniques such as async and defer to improve performance.

- Developers need to be aware of how the order in which JavaScript files are loaded and executed affects the page's cross-browser compatibility.


### Understanding the life cycle of a JavaScript file in a browser can help developers write more efficient code and improve user experience. By optimizing the request, load, and fulfillment process, page load time can be reduced and overall performance improved.

在后端接口封装中，我们一般都会对返回的数据做一个封装，以防止系统出现不可预期的数据结构和类型。比如这样：

结构体 1

{
  "success": true,
  "code": 200,
  "message": "成功",
  "data": {
    "items": [
      {
        "id": "1",
        "name": "小王",
        "identified": "JavaPub博主"
      }
    ]
  }
}
结构体 2

{
    "ret": 200,
    "data": {
        "title": "Default Api",
        "content": "王哥 您好，欢迎使用 apifather!",
        "version": "1.1.0",
        "time": 14231428021
    },
    "msg": ""
}
不论如何定义，多一个或少一个字段，我们都需要统一规范。接下来我们拆解一下，

首先，通过观察，一定要有状态码，也就是案例中的 code 和 ret ，通过状态码可以知道当前程序哪里出了问题，比如 200 就是成功。有同学会问，为何不用 data 来判断，为空或者为 0 就是错误，当然不行。

比如：下面这个结构，data 长度虽然等于 0，但是这属于确实没查到数据，而不是程序出错。

 

{
    "ret": 200,
    "data": [],
    "msg": ""
}
再看 data，这个毋庸置疑，它是接口的核心数据，也是接口对外提供的业务数据。

再看 message 或者称为 msg，它是给状态做一个文字说明。比如，有个老六在定义了一个状态码（666），第一次调用这个接口的同学可能并不知道返回的状态码含义、也不想去查接口文档，我加个描述：（老六的接口不通啦），调用者就一目了然了。

最后看 success 字段，这个字段是为了更规范而加的，方便前端直接将接口响应状态展示。比如：用户登录成功，可以展示一个 true，或者前端在判断时也可以写更简洁的代码 if result.success:。毕竟将（老六的接口不通啦）描述直接展示出来显得不太正式。

 

基于以上几点，我们的返回结构这样定义：

ApiResponse.class

// 定义API响应结构体
public class ApiResponse<T> {
    private int status; // HTTP状态码
    private String message; // 状态信息
    private T data; // 返回的数据，泛型支持返回不同类型的数据

    // 构造函数
    public ApiResponse(ResponseStatus status) {
        this.status = status.getCode();
        this.message = status.getMessage();
    }

    // 带数据的构造函数
    public ApiResponse(ResponseStatus status, T data) {
        this(status);
        this.data = data;
    }

    // Getter和Setter方法
    // ...
}
定义完返回结构后，我们需要定义状态的枚举值。这是为了定一个统一的规范，方便开发时状态码搞混。

// 定义状态码枚举
public enum ResponseStatus {
    SUCCESS(200, "操作成功"),
    ERROR(500, "服务器内部错误"),
    BAD_REQUEST(400, "请求参数错误"),
    NOT_FOUND(404, "资源未找到"),
    UNAUTHORIZED(401, "未授权"),
    FORBIDDEN(403, "禁止访问");

    private final int code;
    private final String message;

    ResponseStatus(int code, String message) {
        this.code = code;
        this.message = message;
    }

    public int getCode() {
        return code;
    }

    public String getMessage() {
        return message;
    }
}
如何使用呢

@GetMapping("/users/{id}")
public ResponseEntity<ApiResponse<User>> getUser(@PathVariable Long id) {
    try {
        User user = userService.getUserById(id);
        if (user != null) {
            return ResponseEntity.ok(new ApiResponse<>(ResponseStatus.SUCCESS, user));
        } else {
            return ResponseEntity.status(HttpStatus.NOT_FOUND)
                                 .body(new ApiResponse<>(ResponseStatus.NOT_FOUND));
        }
    } catch (Exception e) {
        // 这里可以根据异常类型返回不同的错误状态码和消息
        return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR)
                             .body(new ApiResponse<>(ResponseStatus.ERROR));
    }
}
 

这里使用了 Spring 自带的返回结构体 ResponseEntity 进行封装。

获取到的结果是这样的：

{
  "code": 200,
  "message": "操作成功",
  "data": {
    "id": "1",
    "name": "javapub",
    "age": 18
  }
}
