# The Power of OpenAPI Specification
The [OpenAPI Specification](https://swagger.io/specification/) is changing API development. Through its standardized format, such as the following code snippet from an [OAS document](https://support.smartbear.com/swaggerhub/docs/en/get-started/openapi-3-0-tutorial.html):
```yaml
openapi: 3.0.0
info:
title: Example API
version: 1.0.0
paths:
/users:
get:
summary: Retrieve a list of users
responses:
'200':
description: A list of users retrieved successfully
```
In the above code snippet:
* "Example API" is the definition of the API title, and "1.0.0" is the version number.
* A GET action is specified for the `/users` endpoint in order to retrieve a list of users.
* The goal of the operation is briefly described in the `{summary}` column.
* A single response is defined for the [status code '200'](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/200), denoting a successful retrieval. The `responses` column lists this operation's possible [HTTP](https://developer.mozilla.org/en-US/docs/Web/HTTP) responses.
* "A list of users retrieved successfully" is the response description that is shown.
Overall, this code outlines a simple API endpoint for retrieving a list of users.
To help developers work together, the OpenAPI Specification (OAS) provides a standard technique for expressing [RESTful APIs](https://www.redhat.com/en/topics/api/what-is-a-rest-api). Because of its user-friendly, machine-readable interface, developers can easily explore [API complexities](https://resources.axway.com/checklists/4-things-you-need-to-know-about-api-complexity). While OAS supports interaction, APIs can flourish in a variety of environments. It transforms API development and engagement by combining clarity and teamwork.
## Explanation of OpenAPI Specification (OAS) as Swagger's foundation
This industry-leading API documentation tool is built upon the OpenAPI Specification (OAS). OAS serves as a blueprint that defines interactions, behavior and [API structure](https://www.catchpoint.com/api-monitoring-tools/api-architecture#:~:text=What%20is%20API%20architecture%3F,API%20interacts%20with%20other%20components.). For developers, it acts as a universal language, promoting smooth teamwork and communication across various projects.
OAS sets a universal format for RESTful APIs, covering endpoints, [parameters](https://rapidapi.com/blog/api-glossary/parameters/#), [responses](https://developer.mozilla.org/en-US/docs/Web/API/Response), and [authentication](https://developer.mozilla.org/en-US/docs/Glossary/Authentication). This standard ensures clear, consistent [API design](https://stackoverflow.blog/2020/03/02/best-practices-for-rest-api-design/) and documentation across languages and frameworks. By utilizing OAS, developers gain access to a comprehensive toolkit for API design, documentation, and [testing](https://en.wikipedia.org/wiki/API_testing). Embracing OAS enables interactive, user-friendly API documentation, enhancing the developer experience. OAS evolves continuously, incorporating community feedback and industry best practices to keep its tools up-to-date, changing evolving needs.
## Briefly describe OAS key aspects (endpoints, parameters, responses)
The OpenAPI Specification (OAS) has transformed API definition, providing a standardized method that simplifies development and documentation. It covers crucial API elements like endpoints, parameters, and responses.
- The routes or [URLs](https://developer.mozilla.org/en-US/docs/Learn/Common_questions/Web_mechanics/What_is_a_URL) that users rely on to access certain features or resources are known as endpoints, and they serve as the entry points to an API. OAS gives developers a structured overview of the API's capabilities by enabling them to clearly specify these endpoints and the `HTTP` methods (like `GET`, `POST`, `PUT`, and `DELETE`) that each endpoint supports.
- Parameters further enhance the flexibility and usability of APIs by allowing clients to customize requests. OAS enables developers to specify various [types of parameters](https://rapidapi.com/guides/rest-parameter-types), including [path parameters](https://help.iot-x.com/api/how-to-use-the-api/parameters/path-parameters) (embedded in the endpoint URL), [query parameters](https://guides.emberjs.com/release/routing/query-params/) (appended to the URL), [header parameters](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers) (included in the [request headers](https://developer.mozilla.org/en-US/docs/Glossary/Request_header)), and [request body](https://swagger.io/docs/specification/describing-request-body/) parameters (sent in the [request payload](https://docs.itential.com/opensource/docs/request-payload)). Developers guarantee consistency and clarity in client-API interactions by specifying parameters in the API definition.
- Any API connection begins and ends with responses describing the information or actions the server returns to the client in response to their requests. OAS gives developers the ability to specify the format and content of API responses, such as [headers](https://budibase.com/blog/inside-it/api-headers/), [status codes](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status) and [response bodies](https://developer.mozilla.org/en-US/docs/Web/API/Response/body). Developers give clients essential advice on how to properly analyze and handle API responses by providing response formats and examples.
# Getting Started with Swagger
With this tool, you can easily define, document , and display APIs, therefore improving the understanding and installation process for both internal and external developers. Now, let's get started and explore how to simplify web development with this tool.
## Outline options for using Swagger (online tools, local installations)
Developers have many choices for API documentation. One common strategy is using internet resources like [SwaggerHub](https://swagger.io/tools/swaggerhub/). These cloud-based platforms facilitate the design, documentation , and deployment of APIs in a convenient and easily accessible environment. Online tools improve team cooperation and streamline documentation with features like [version control](https://www.atlassian.com/git/tutorials/what-is-version-control) and collaborative editing.
Developers have the option to install tools such as the [OpenAPI Editor](https://swagger.io/tools/swagger-editor/) and [UI](https://swagger.io/tools/swagger-ui/) locally, providing more control and customization. For individuals who prefer local development environments or have privacy and regulation concerns that demand offline solutions, this [open-source](https://opensource.com/resources) suite offers offline access.
## Guide readers on choosing the appropriate option
Developers who prefer to work offline or live in places with poor internet connections might greatly benefit from local installations that give them more control and offline access. They allow them to customize and fit the environment to certain requirements. Depending on the project's requirements, teamwork, and workflow, one can choose between local installation and online tools. While some people choose local installation for control and customization, others prefer online tools for ease of use.
Developers have two options for working with API documentation tools:
* Online Tools: Team members can work together thanks to platforms like the API management tool.
* Local Installations: More customization and offline access are provided by tools like the OpenAPI Editor.
This increases developer productivity for the development of excellent APIs by enabling them to easily produce and manage API documentation.
# Creating Your First API Documentation
Creating your first set of API documentation is a great first step toward bringing your product into the public domain. Regardless of your experience as a developer, having clear and understandable documentation is important for others to fully understand and successfully connect with your API.
To start, outline your API's key features and endpoints. These form the foundation for developer interaction. Then, thoroughly document each endpoint, covering [request/response structures](https://help.vidizmo.com/support/solutions/articles/17000111404-understanding-rest-api-request-response-structure), authentication, and [error handling](https://www.dremio.com/wiki/error-handling/). Use simple language and clear examples. Include interactive examples and code samples to aid understanding. Cover questions and challenges newcomers might face, and address these in your documentation to make it user-friendly and valuable for developers.
## Introducing core elements for creating API definitions using Swagger Editor
Creating strong and well-defined APIs is necessary for smooth communication between applications. By providing a standard method for defining endpoints, parameters, answers , and authentication techniques, API design techniques speed up this process. Its standout feature is the ability to write API definitions with OpenAPI Specification (OAS), previously known as the Swagger standard.
Now, let's delve into some of the core elements for creating API definitions using its editing tool:
- [Paths and Operations](https://swagger.io/docs/specification/paths-and-operations/): Paths represent API endpoints, while operations define actions like `GET`, `POST`, `PUT`, `DELETE`, etc. You can effectively set the path, operation, and arguments for each endpoint with this API Design Editor.
- Parameter: These enable the transfer of data between API endpoints, such as request bodies, path parameters, headers, and [query parameters](https://www.branch.io/glossary/query-parameters/). Parameters for operations such as necessary status and [data types](https://swagger.io/docs/specification/data-models/data-types/) can be defined.
- Responses: Describe the information the API provides in response to a request. It provides clear documentation on the anticipated output for each endpoint and allows you to set response codes and formats.
- Security Definitions: With the use of this editing tool, security protocols such as [API keys](https://swagger.io/docs/specification/authentication/api-keys/), [OAuth](https://www.fortinet.com/resources/cyberglossary/oauth), or [JWT tokens](https://jwt.io/introduction) can be defined.. You can set security requirements at the API or operation level, ensuring authorized access to endpoints.

## Getting Started
In this section, we’ll be setting up the UI for our server and the processes for this setup are very easy to implement, let dive into the installation process.
### Installation / Configuration
To begin, API documentation interface and docs. Just execute the provided code in your project's root terminal to start the installation process.
```shell
npm i swagger-ui-express swagger-jsdoc
```
After installing, you have to clone the server project in [GitHub](https://github.com/).
Once you've installed the code, you can go to the `server.js` file where you'll find a portion of the code demonstrating the implementation, which we'll explain in detail shortly.
Importing it's Libraries:
```javascript
const swaggerJsdoc = require("swagger-jsdoc");
const swaggerUi = require("swagger-ui-express");
```
In this section, we are bringing in two libraries named `swagger-jsdoc` and `swagger-ui-express`. These libraries assist us in utilizing this tool designed for API documentation.
Configuration:
```javascript
const options = {
definition: {
openapi: "3.0.0",
info: {
title: "OpenReplay Swagger Example API",
version: "1.0.0",
description: "A simple API to demonstrate Swagger",
},
servers: [
{
url: "http://localhost:3001",
},
],
},
apis: ["./routes/*.js"], // Path to the API routes
};
```
In this section, we provide specific information such as the version of OpenAPI we're utilizing `(openapi: "3.0.0")`, details about our API, including its title, version, and description, and the URL of the server hosting our API. Additionally, we define a [wildcard path](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Regular_expressions/Wildcard) `(./routes/*.js)` for the tool to search for our API routes.
Generating API Specifications:
```javascript
const specs = swaggerJsdoc(options);
```
In this step, we're creating the specifications using the settings we set up previously. The `specs` variable will contain all the necessary details that are required to generate the documentation for our API.
Setting Up the UI Endpoint:
```javascript
app.use("/api-docs", swaggerUi.serve, swaggerUi.setup(specs));
```
This code creates a route called `/api-docs` within our Express application. When we go to this route in a web browser, the UI will be displayed, presenting the documentation for our API generated from the specifications we made earlier.
Including API Routes:
```javascript
app.use(require("./routes/users"));
```
This line includes the API routes that are specified in the `users.js` file found in the `routes` directory. These routes will be documented according to the specifications we've given.
Handling 404 Error:
```javascript
app.get("*", (req, res) => {
res.status(404).send(JSON.stringify("404"));
});
```
This section deals with requests to routes that haven't been defined. It sends back a 404 error code along with the message "404."
### Defining the API endpoints
In the closed server project, you'll discover a `routes` folder that holds a file named `users.js`. This file contains the server's endpoints and code for showcasing the UI component for each endpoint. Below, you'll find the complete code, along with explanations.
GET `/users` Route:
```javascript
/**
* @swagger
* /users:
* get:
* summary: Get all users
* description: Retrieve a list of all users
* responses:
* '200':
* description: A list of users
*/
router.get("/users", (req, res) => {
// Your logic to get all users
res.send([
{
username: "Mike John",
age: 20,
email: "mike@gmail.com",
},
{
username: "Jane Smith",
age: 50,
email: "jane@gmail.com",
},
]);
});
```
This piece of code establishes a `GET` route located at `/users`. The annotations serve to document this endpoint:
- Summary: Offers a brief overview of what the endpoint does.
- Description: Provides a more elaborate explanation of what the endpoint accomplishes.
- Responses: Details the potential responses that the endpoint may provide, including status codes and descriptions.
POST `/create-new-users` Route:
```javascript
/**
* @swagger
* /create-new-users:
* post:
* summary: Create a new user
* description: Create a new user with the provided data
* requestBody:
* required: true
* content:
* application/json:
* schema:
* type: object
* properties:
* username:
* type: string
* email:
* type: string
* age:
* type: number
* responses:
* '200':
* description: User created successfully
* '400':
* description: Bad request
*/
router.post("/create-new-user", (req, res) => {
// Your logic to create a new user
res.send({
message: "User created successfully",
});
});
```
A POST route is created at `/create-new-users` by this section of the code. Additionally, comments are included to clarify the endpoint:
- `summary`: A brief overview of the endpoint's abilities.
- `description`: More detailed information about the endpoint's function.
- `requestBody`: Explains the format that should be used for this endpoint in the request body.
- `responses`: Contains information about the possible answers the endpoint could provide, such as status codes and explanations.
Below is the output of its UI displaying the `GET` and `POST` endpoints:
## Walk through defining an endpoint (method, URL, parameters, responses)
Creating an endpoint establishes the foundation for every step that follows in the development process, much like constructing a building. Let's look into the method, URL, parameters and responses to establish a reliable and functional endpoint in this important phase.
The first thing we do is identify the `HTTP` method, which controls what the endpoint does. Choosing the right method is crucial, whether it's a `GET` for data retrieval, `POST` for resource creation, `PUT` for modifying already-existing resources, or `DELETE` for their removal.
Next, we craft the URL, the address that uniquely identifies the endpoint. This URL should be descriptive, concise, and follow RESTful principles, making it simple for developers to understand its purpose and usage.
Next are the parameters, which offer more details required to run the endpoint. Depending on the type of endpoint, these could be query parameters, request headers, or request body parameters. A detailed review of the parameters guarantees that the endpoint is flexible and suitable for a range of use cases.
Lastly, we define response, which describes the contents that the endpoint returns following a successful execution. This involves sending the response body with relevant data or error messages, as well as the `HTTP` status codes, such as 200 for success or 404 for not found.
# Utilizing Swagger UI

They are different types of testing techniques are used to checking the Functional & Non Functional testing.
The main difference between Functional and Non Functional testing are,
1. Functional testing to test the software application to works.
Non Functional testing to test the performance of the functional testing application software to works.
2.Functional testing to check the expected result of the program.
Non Functional testing to check the speed & over load of the application to works.
Example for Functional testing:
In some of the application, we need to check the iron to click it works correct or not. We add/detect the product in craft, it will increase or decrease to be checked.
Eg for Non Functional testing:
In some of the application, we need to check N numbers of users to access the same application at a time, we need to check speed & performance of the site. | tamizh | |

</div>
While the digital world thrives, the need for physical copies persists. [Designing web content for printing](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_media_queries/Printing) offers several advantages:
* Offline Access: Not all users have constant access to digital devices or reliable internet connections. Enabling users to print web content gives them offline access, making information more accessible and inclusive.
* Customization: Print design allows for a level of customization and personalization that digital design often can't match. Users can add annotations, highlight important sections, or organize content in a preferred format. This level of flexibility enhances the user experience and utility of printed materials.
* Archiving: Printing web content allows users to create physical copies for archival, documentation, or reference purposes. This is particularly valuable for educational materials, legal documents, receipts, and reports.
* Enhanced Readability: In some cases, users may find reading lengthy content on paper rather than on a screen easier.
* Regulatory Requirements: In many industries, such as finance, healthcare, and legal sectors, regulatory requirements mandate the provision of printable versions of web content for compliance and record-keeping purposes.
## Differences Between Designing for Digital Screens and Physical Print
While both digital and print design aim to communicate information visually, the way we approach them differs significantly due to each medium's inherent limitations and functionalities. It is essential to understand these differences to create effective print-optimized web content.
Unlike digital design, where layouts can adjust to any screen size, print design works with a fixed canvas in a specific portrait or landscape orientation. While digital designs leverage the vast RGB color spectrum for rich visuals, print design is limited by the [CMYK (Cyan, Magenta, Yellow, Key Black) color model](https://www.colorsexplained.com/cmyk-color-model/), requiring careful color selection to avoid unwanted variations in print.
Digital content thrives on interactivity with features like scrolling and clicking. Print media, however, is static, relying on precise navigation and well-organized elements to communicate information effectively.
Resolution is a crucial consideration for digital design, with elements needing optimization for various device pixel densities. On the other hand, print design demands high-resolution images to prevent pixelation and blurry visuals in the final output.
The core focus of digital design is user engagement and interactivity, often achieved through animations, hover effects, and calls to action. In contrast, print design prioritizes readability and clarity, emphasizing effective use of typography, white space, and layout for optimal information presentation.
### Challenges in Designing Web Content for Physical Outputs
Designing for print presents distinct challenges compared to digital screens. You must address these challenges to seamlessly transition from digital to physical mediums.
Some of the common challenges include:
* Fixed Page Size: Unlike responsive web design, printed content has a fixed page size and orientation (portrait or landscape). Layouts need to adapt to fit these constraints.
* Limited Color Palette: Printers typically use a CMYK, which has a smaller range of colors than the RGB (Red, Green, Blue) spectrum used on screens. This can lead to color variations in the printed output.
* Media Compatibility: Images and media types optimized for digital viewing may not translate well to print. Print optimization involves selecting high-resolution images, adjusting color profiles, and ensuring media formats are compatible with print processes.
* Lack of Interactivity: Printed content lacks the interactive elements on websites. Navigation menus, hover effects, and animations must be replaced with static alternatives.
* Page Breaks and Pagination: Long-form content designed for scrolling on digital screens may need to be paginated for print. Managing page breaks and content flow to avoid awkward breaks or fragmented content is essential for a cohesive print reading experience.
* Resolution Roadblock: Those crisp images that look fantastic on your screen might turn pixelated and blurry in print. High-resolution images (typically 300 DPI or higher) are crucial for clean and sharp visuals in printed outputs.
* Accessibility Considerations: Accessibility features like alt text for images, structured headings, and screen reader compatibility must be preserved in print formats to ensure accessibility for users with accessibility needs.
We've explored the hurdles of designing web content for print. But fear not! CSS emerges as our trusty weapon to overcome these limitations and craft a print-optimized experience.
Let's delve into how CSS empowers us to tackle these challenges:
## Using Media Queries to Target Print-Specific Styles
Media queries are potent tools in CSS for applying different styles based on various conditions, such as screen size, device orientation, or print media. When targeting print-specific styles, [media queries](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_media_queries/Printing#using_media_queries_and_page_to_control_printed_content) enable you to customize the appearance of a document specifically for printing.
Here's how media queries can be used to target print-specific styles:
```css
@media print {
/* Your print-specific styles here */
}
```
The `@media print` rule initiates a media query targeting styles specifically for printing scenarios. Any CSS styles placed within the curly braces {} will only be applied when the document is printed.
## Print Headers and Footers
Have you ever flipped through a book or document and noticed consistent headers and footers gracing each page? That's the magic of print headers and footers! They enhance the professionalism of your printed content and provide valuable information like page numbers, website URLs, or company logos.
Headers and footers are essential in print design, providing context, navigation, and branding information on printed pages. CSS offers powerful tools for adding headers and footers to printed content.
Here's how you can incorporate headers and footers using CSS:
### The Positioning Approach
You can leverage the `position` property to fix headers and footers to the top and bottom of the page, respectively.
Here is how to do this:
```css
@media print {
/* Header Styling */
.header {
position: fixed;
top: 0;
left: 0;
right: 0;
}
/* Footer Styling */
.footer {
position: fixed;
bottom: 0;
left: 0;
right: 0;
}
}
```
Here, we wrap the styles within a `@media print` block to ensure they only apply when printing the document and define classes like `.header` and `.footer` for styling the header and footer content, respectively. Setting `position: fixed` on elements with `top: 0` for headers and `bottom: 0` for footers will make them stick to those positions on every printed page. Then, adjust `left: 0` and `right: 0` to span the entire width of the page.
### Table Approach
This method utilizes the power of [HTML tables](https://blog.openreplay.com/designing-interactive-beautiful-tables-with-css/). By wrapping your content in a table, you can define separate sections for the header (`<thead>`), body (`<tbody>`), and footer (`<tfoot>`). Browser magic takes care of repeating the header and footer rows on every printed page.
Here's an example:
```html
<table>
<thead>
<tr>
<th>Header Cell</th>
</tr>
</thead>
<tbody>
<tr>
<td>Body Cell</td>
</tr>
</tbody>
<tfoot>
<tr>
<td>Footer Cell</td>
</tr>
</tfoot>
</table>
```
Here, we wrap our content within an HTML table, with the `<thead>` section defining the header row that you can repeat on every printed page, the `<tbody>` section holding your main content, and the `<tfoot>` section defining the footer row that will also be repeated on every printed page.
You can choose the proper method based on your preference. The positioning method offers more flexibility regarding styling and placement, while the table method is more straightforward to implement and works well for basic headers and footers.
You can also integrate additional approaches for achieving headers and footers using the approaches below:
### Using the `@page` Rule
CSS provides the `@page` rule, which allows you to define styles specifically for printed pages. To create a header, you can use the `@page` rule with the `@top-center`, `@top-left`, or `@top-right` descriptors followed by the content you want to include in the header, as shown below:
```css
@page {
@top-center {
content: "Header content here";
}
}
```
Similarly, you can create footers using `@bottom-center`, `@bottom-left`, or `@bottom-right` descriptors, as shown below:
```css
@page {
@bottom-center {
content: "Footer content here";
}
}
```
### Adding Page Numbers
You can include page numbers in headers or footers using the `content` property and the `counter()` function in CSS. Define a counter in your CSS stylesheet and increment it for each printed page.
Here is an example:
```css
@page {
@bottom-right {
content: "Page " counter(page);
}
}
```
Here, the `@bottom-right` descriptor specifies where the content should be placed on the printed page. In this case, it indicates that the content ("Page " counter(page)) should be placed at the bottom-right corner. The `content: "Page " counter(page);` line defines the content to be displayed in the specified location, with `"Page "` being a static text string that will appear before the page number and `counter(page)` automatically incrementing each printed page. It represents the page number.
Note: You won't see the page number displayed on the web page using `counter(page)` during the printing preview because it generates the page number specifically for the printed output. This functionality doesn't translate directly to displaying the page number on the web page itself.
<CTA_Middle_Basics />
### Practical Example for Optimizing Header and Footer for Physical Output
Imagine you're to create a printed user manual or technical guide for a tech device, optimizing the web page header and footer for print readability and presentation.
Here is how you can do this:
```html
<!-- Header -->
<header>
<h1>Tech Solutions</h1>
</header>
<!-- Main content -->
<main>
<section>
<h2>User Manual: XYZ Tech Device</h2>
<p>Model: XYZ-1000</p>
<p>Version: 2.0</p>
<h3>Features:</h3>
<ul>
<li>Wireless connectivity</li>
<li>High-definition display</li>
<li>Touchscreen interface</li>
<li>Advanced security features</li>
</ul>
</section>
</main>
<!-- Footer -->
<footer>
<p>Tech Solutions © 2024. All rights reserved.</p>
</footer>
```
```css
body {
font-size: 25px;
background-color: #dc9999;
}
/* Styles for printed pages */
@media print {
/* Header */
header {
position: fixed;
top: 0;
left: 0;
right: 0;
text-align: center;
background-color: #ccc;
border-bottom: 2px solid #ee1b1b;
}
/* Footer */
footer {
position: fixed;
bottom: 0;
left: 0;
right: 0;
background-color: #ccc;
text-align: center;
border-bottom: 2px solid #ee1b1b;
font-size: 30px;
}
}
```
Here is the output for the web page display:
Here is the output for the printing preview:
The `@media` print query targets printing styles specifically. Within this query, the header is positioned fixed at the top of the page (position: fixed) with a centered text alignment. It also has a 2px solid red bottom border (`border-bottom: 2px solid #ee1b1b`). Similar to the header, the footer is positioned fixed at the bottom of the page with a centered text alignment, background color, and a 2px solid red bottom border. Additionally, the font size of the footer text is increased to 30px for better visibility.
On the web page, the content is positioned to the left, but in the printing preview, the header and footer are placed to the center, and the styles applied are evident, as opposed to the web page display version.
## Page Break Control
This section will explore techniques for controlling page breaks in the printed output of your HTML documents. Controlling page breaks in printed output and specifying page breaks within long documents are essential aspects of optimizing web pages for print.
Here are some techniques and examples to demonstrate how to achieve this:
### Using CSS `page-break` Properties
You can use CSS properties like `page-break-before`, `page-break-after`, and `page-break-inside` to control page breaks. This method utilizes the `@media print` media query to target styles specifically for printing scenarios.
For example, to force a page break before an element, you can use `page-break-before: always;`. Also, within the media query, you can use the `page-break-after` property on specific elements to force a page break to occur after that element.
Here is how you can use `@media print` with `page-break-after`:
```css
@media print {
.page-break {
page-break-after: always;
}
}
```
In this example, any element with the class "page-break" will force a page break after it when printed.
### Manual Page Breaks
You can insert a `<br>` element with the style `page-break-after: always` within your HTML code to manually trigger a page break at that point.
Here is an example of how to do this:
```html
<p>Content before the page break...</p>
<br style="page-break-after: always;">
<p>Content after the page break...</p>
```
This example inserts a `<br>` element with `page-break-after: always` to force a page break after the first paragraph.
While most modern browsers support `page-break-after`, there might be slight differences in interpretation across different versions and browsers. Testing in your target browsers is recommended.
Alternatively, you can use a `<div>` element with the class "page-break" and define the `page-break-after` property in your CSS using the `@media print` query:
```html
<div class="page-break"></div>
```
```css
@media print {
.page-break {
page-break-after: always;
}
}
```
This approach offers more flexibility for styling the element around the page break if needed.
### Demonstrating Page Breaks Insertion
Assuming you need to control the page breaks to optimize the printing of lengthy content such as books, reports, or manuals. Here's an example demonstrating how to insert page breaks within a long document:
```html
<h1>Chapter 1: Introduction</h1>
<p>
Lorem ipsum dolor sit ameft consectetur adipisicing elit. Obcaecati rem ipsa
odio repudiandae quos, non porro modi expedita natus placeat quis suscipit
vitae recusandae voluptatibus saepe commodi adipisci repellat incidunt illo
dolore amet nisi ipsam maxime fugit? Similique praesentium tempora illo
deserunt soluta. Animi accusantium corrupti beatae adipisci recusandae in
quidem numquam, officiis odit illum nam rerum sit sed? Esse labore
perspiciatis voluptatem eum optio enim quo at est nihil laborum.
</p>
<div class="page-break"></div>
<h1>Chapter 2: Detailed Explanation</h1>
<p>
Lorem ipsum dolor, sit amfet consectetur adipisicing elit. Sapiente vero quos
dolores mollitia reprehenderit dignissimos tempore animi, cum, veniam suscipit
ullam ea dolorem enim at non ex! Animi magni eaque molestias eos expedita
praesentium doloribus ratione! In accusantium suscipit nemo ad harum eligendi,
eveniet sit optio atque ullam inventore assumenda, corrupti pariatur, quo quae
saepe delectus. Error quo accusamus id fugit sit libero alias minima beatae
quia dicta unde architecto aperiam, quis enim quaerat consectetur nulla quae
laborum, culpa aspernatur dignissimos quos ipsum quam ex. Suscipit, accusamus
ea voluptates mollitia ipsum quibusdam reprehenderit? Mollitia, eaque atque
nihil doloribus aperiam numquam!
</p>
<div class="page-break"></div>
<h1>Chapter 3: Conclusion</h1>
<p>
Lorem, ipsum dolor sit ameft consectetur adipisicing elit. Vel, quas eius
veritatis commodi, quis architecto ullam ab eaque quos hic fugiat itaque illo
reprehenderit pariatur ratione praesentium possimus aut nostrum magnam numquam
ea nobis? Molestiae praesentium nulla vel possimus dolore, voluptate incidunt
impedit excepturi labore dolorem quae porro voluptatum harum doloribus itaque
aperiam in atque assumenda eveniet est, provident alias ab.
</p>
```
```css
body {
font-size: 19px;
background-color: #dc9999;
}
@media print {
.page-break {
page-break-after: always;
}
h1 {
font-size: 38px;
}
p {
font-size: 33px;
}
}
```
Here, the `.page-break` class is used to apply the `page-break-after: always;` property, ensuring that a page break occurs after each chapter. When you print this document or preview it in print mode, you should see each chapter starting on a new page due to the page break specified after each `<div class="page-break"></div>` element, as shown below.
Here is the output as displayed on the web page:

## Content Adjustment
Content adjustment for printing involves hiding or modifying specific elements to improve the printed output. Here are some techniques for hiding or modifying content for printing purposes:
* You can achieve this using `@media print` with CSS. This method leverages the `@media print` media query to target styles specifically for printing scenarios. Within the media query, you can use CSS properties like `display: none;` to hide unwanted elements on the printed page.
Here is an example:
```css
@media print {
.navigation-bar,
.footer {
display: none; /* Hide navigation bars and footers */
}
}
```
* You can also modify web element styles specifically for printing using the `@media print` media query.
Here is an example:
```html
<body>
<p id="content">This content will appear on both screen and print.</p>
</body>
```
```css
@media print {
p#content {
font-size: 18px; /* Adjust font size for printing */
}
}
```
In this example, the `#content` paragraph will have a larger font size (18px) when printed. You can use various CSS properties within the `@media print` block to modify the content's appearance for printing, such as font size, font weight, color, and margin.
* Let's look at a practical example to demonstrate how to hide navigation bars and footers for printing using` @media print`:
```html
<header>
<h1>This is the Document Title</h1>
</header>
<nav>
<ul>
<li><a href="#">Home</a></li>
<li><a href="#">About</a></li>
<li><a href="#">Contact</a></li>
</ul>
</nav>
<main>
<h1>Main Content</h1>
<p>This is the main content of the document.</p>
<p>This is another paragraph with more content.</p>
</main>
<footer>
<h1>Footer section</h1>
<p>© 2024 My Company Name</p>
</footer>
```
```css
body {
font-family: Arial, sans-serif;
background-color: #dc9999;
}
header,
main,
footer {
padding: 0.5em;
}
p {
font-size: 28px;
}
nav {
background-color: #bbd4e5;
padding: 30px;
}
nav li {
display: inline-block;
margin-right: 15px;
font-size: 24px;
}
/* Hide navigation bar and footer for printing */
@media print {
nav,
footer {
display: none;
}
}
```
In the above example, the `@media print` block, the `nav` and `footer` elements, are set to `display: none`, which hides them from the printed output. This ensures that these elements are not included in the printed version of the document, just as seen in the output below:
Here is the web page display:

## Typography for Printing
You can incorporate effective typography practices to enhance the readability and user experience of your printed documents.
Here is an example:
```css
@media print {
body {
font-size: 12pt; /* Adjust font size for print */
margin: 0; /* Remove default margins */
}
}
```
Here, the `body` selector targets the `<body>` element of your HTML document, setting `font-size: 12pt;` which sets the font size to 12 points for all text within the `<body>` when the page is printed. Point (pt) is a unit of measurement commonly used in print media. The `margin: 0;` property sets the margin of the `<body>` element to 0 when printing. By setting the margin to 0, you remove any default margins that may be applied by the browser or user agent, ensuring that the content starts from the edge of the page.
Let's look at a practical example demonstrating how to modify web elements for print:
```html
<h1>Main Heading</h1>
<p>This is a paragraph of text.</p>
<h2>Subheading</h2>
<p class="important-text">This text is important and should stand out.</p>
```
```css
body {
font-size: 24px; /* Set default font size */
background-color: #dc9999;
}
.important-text {
font-size: 26px; /* Larger font size for important text */
font-weight: bold;
color: #ee1b1b; /* Red color for emphasis */
}
/* Print-specific styles */
@media print {
body {
font-size: 38pt; /* Adjust font size for print */
margin: 0; /* Remove default margins */
font-family: Arial, Helvetica, sans-serif;
}
.important-text {
color: #1217a2; /* Change color for print */
font-size: 28pt;
font-style: italic;
}
}
```
This example displays on the screen with a default font size of 24 pixels, a background color of #dc9999, and emphasized text in red (#ee1b1b) at a font size of 26 pixels with bold weight. It has a larger font size of 38 points, a dark blue color (#1217a2) for emphasized text, and emphasized text in italic style at a font size of 28 points on print. The font family for the print version will be Arial, Helvetica, and sans-serif.
Here is the output as displayed on the web page:
Here is the previewed output for printing:
## Print Optimization Considerations
When preparing content for print, several crucial factors come into play to ensure the best possible output. This section delves into critical considerations for print optimization, including color management, typography, layout optimization, and image optimization techniques. Understanding and implementing these considerations can significantly enhance the quality and readability of printed materials.
Here are some strategies and guidelines:
* Color Management: You need to address discrepancies between monitor color gamuts and printer capabilities. Ink and paper variations can also affect color representation. To ensure color consistency, calibrate your monitor, use the CMYK color model, and utilize soft proofing features in design software. Also, Ensure high contrast between text and background, avoid low-contrast color combinations, and prioritize clear fonts for optimal readability.
* Typography: Selecting appropriate fonts and sizes impacts readability. For body text, prioritize clear, easy-to-read fonts like Arial or Helvetica. Use serif fonts like Times New Roman sparingly for emphasis and avoid decorative or script fonts. Also, maintain adequate line spacing, use left-aligned text for body content, implement sufficient margins, and test your typography choices in print.
* Layout Optimization: Optimize layout for print by adjusting page size, margins, and orientation to suit different print formats. Utilize CSS media queries to modify layout properties for print, controlling page breaks and columns for improved presentation.
* Image Optimization: Understand that resolution (PPI) affects image quality in print. Most printers require at least 300 PPI for good results. Use high-resolution images, resize using quality-preserving methods (bicubic interpolation), consider lossless image formats like PNG or TIFF, and test resized images at the desired print size.
## Conclusion
This detailed guide has explored various aspects of print optimization, empowering you to create documents that are not only informative but also visually appealing and ready for high-quality print output. By following these guidelines and implementing the recommended techniques, you can optimize the quality and professionalism of your printed materials. Remember to test your print output regularly to refine your optimization approach and ensure a successful outcome.

1,921,213 | Django Admin: customize the auth system | Django admin is insanely good for an out-of-the-box lean and clean admin panel; it's not the most... | 0 | 2024-07-12T13:58:15 | https://dev.to/kwnaidoo/django-admin-customize-the-auth-system-58pd | webdev, programming, tutorial, python | Django admin is insanely good for an out-of-the-box lean and clean admin panel; it's not the most "sexy" looking dashboard around but it gets the job done for internal company tools.
If you don't like the look and feel of Django Admin but want to be lazy like me and re-use the auth system to get a basic login/logout starting point, this tut is for you!
## Routes
In your "urls.py" add these to your routes:
```python
from django.urls import path
from myapp.views import (
login_view,
logout_view,
)
urlpatterns = [
...
path("accounts/login/", login_view, name="accounts_login"),
path("accounts/logout/", logout_view, name="accounts_logout"),
]
```
## Controller methods
Now let's handle our login routes in "myapp/views.py":
```python
def login_view(request):
error = None
form = LoginForm()
if request.method == "POST":
form = LoginForm(request.POST)
if form.is_valid():
username = form.cleaned_data["username"]
password = form.cleaned_data["password"]
user = authenticate(request, username=username, password=password)
if user:
login(request, user)
if user.is_superuser:
return HttpResponseRedirect("/admin/")
return HttpResponseRedirect("/dashboard")
else:
error = "Login failed. Please check your details and try again."
return render(request, "login.html", {"form": form, "error": error})
```
As is the standard with all Django forms, you need a form object for this login view, so add this to "forms.py"
```python
from django import forms
class LoginForm(forms.Form):
username = forms.CharField(label="Your username", max_length=100)
password = forms.CharField(widget=forms.PasswordInput())
```
Handling the logout is as simple as:
```python
def logout_view(request):
logout(request)
return HttpResponseRedirect("/accounts/login")
```
## A login template
Now that you have a basic login in place, we need to add our "login.html" form as follows:
```python
<form action="/accounts/login/" method="post" class="login-form">
{% csrf_token %}
<div class="form-group">
<input type="text" name="username" class="form-control rounded-left" placeholder="Username" required>
</div>
<div class="form-group d-flex">
<input type="password" name="password" class="form-control rounded-left" placeholder="Password" required>
</div>
<div class="form-group">
<button type="submit" class="btn btn-primary rounded submit p-3 px-5">Login</button>
</div>
</form>
```
For readability, I kept the markup stupidly simple, but the essential here is the actual form that captures the user's details and posts to our login route.
## Protecting routes
```python
from django.contrib.auth.decorators import login_required
@login_required
def dashboard(request):
# access the user's information via request.user
```
You can use this decorator anywhere in your views.py to restrict access to any route you wish.
>💡 Want some of that Next.js Kool-Aid everyone is drinking without having to deal with JS? Try [Django Unicorn](https://www.django-unicorn.com/). It's open-source and super easy to implement.
## Conclusion
Wasn't that such a breeze? Django is a powerful framework, that will make you super productive regardless of how big or small your application is.

Philosophy ... Love of wisdom
META ... Beyond
🔰 MetaPhilosophy is Beyond the Love of Wisdom. What is Beyond the Love of Wisdom❓
🧩 Wisdom is Truth Itself & Truth Represents the Right Boundaries
🎯 Loving Wisdom Means Loving the Right Boundaries
Right Boundaries Provide Clarity So They Are Easily Understood
⭕️ Philosophy Loves Clarity, Not Accumulating Confusion (Polemic)
❇️ Going Beyond Clarity Means Foundational
❇️ Foundational Means Absolute, So MetaPhilosophy Goes Beyond Clarity Which Also Means At the Foundational Point
Which Also Means Being MetaPhilosophical Is Being at the Foundation - Absolute, So MetaPhilosophy Explores the Dimension of Absoluteness
UNDERSTANDING METAPHILOSOPHY EASILY
To make it easier to understand MetaPhilosophy❓
Exploring Absoluteness
MetaPhilosophy seeks to understand the fundamental wisdom of what is considered most fundamental.
Beyond Rationality
Despite rationality being considered the foundation of philosophical reasoning, even rationality is not easily understood if it is not realistic.
What is considered rational is sometimes difficult to understand realistically, except as mere overlapping logical conclusions.
Subjective-Objective
MetaPhilosophy must be able to see the objective side of the subjective, and see the subjective side of the objective.
So as not to mistakenly understand the concrete in an abstract way and vice versa, which would take it out of context.
Context & Perspective
MetaPhilosophy must be able to see context differently from perspective and not equate "different contexts" as "different perspectives," though they are different.
⭕️ THIS IS THE MAIN MISTAKE IN PHILOSOPHY THAT BECOMES THE ROOT OF MANY POLEMICS
Philosophical Ambiguity
MetaPhilosophy must be wary of ambiguity in philosophy, in order to find universal truth
Beyond Cause and Effect
MetaPhilosophy must reason beyond cause and effect (beyond relative logical consequences)
WORLD VIEW ON METAPHILOSOPHY
The Problem of METAPhilosophy❓
⭕️ They didn't grasp the concept of MetaPhilosophy. They only see METAPhilosophy as 'philosophy about philosophy'❓So ambiguous.
So, unlike what is generally known in the world that MetaPhilosophy is philosophy about philosophy❓Which is still ambiguous because they themselves are confused in formulating the concept of MetaPhilosophy and then their confusion considers MetaPhilosophy no different from or part of philosophy ❌
But actually ...
📌 SO, MetaPhilosophy fundamentally is
1⃣ ❇️
Tracing Universal Truth and Applying Knowledge Contextually
Practically ...
2⃣ ❇️
Reasoning Equally (Subjective-Objective) Based on Premises Beyond Cause and Effect (Absolute Logical Consequences)
Experimentation
This means that if previous philosophy only contemplated with thoughts far from experimentation, MetaPhilosophy must base its knowledge on experimental evidence or conduct experiments itself.
The difference between science and MetaPhilosophy is that if science seeks to find the truth of probability from the results of its experiments, MetaPhilosophy must be able to see the universal truth from its experimental results.
3⃣ ❇️
Fundamentally, MetaPhilosophy deals with universal absolute truth. Whatever is touched, studied, communicated, or approached by MetaPhilosophy, always seeks the underlying universal absolute truth. 📌
So it is time for science to trust philosophy through MetaPhilosophy, where their synergy will occur - sooner or later.
🔰 Science is the hand of MetaPhilosophy, and vice versa.
🔰 I THINK THIS IS ENOUGH TO EXPLAIN WHAT METAPHILOSOPHY IS

1,921,218 | Justified Cognitive | This the 1st, initial step is to ensure avoidance of cognitive biases. Don’t focus on logical... | 0 | 2024-07-12T13:41:39 | https://dev.to/seremonia/justified-cognitive-313m | metaphilosophy, cognitivebias | This the 1st, initial step is to ensure avoidance of cognitive biases. Don’t focus on logical rule-checking first. Instead, focus on avoiding cognitive biases.
It's like not trying to apply logic to something that is inherently beyond logic. Isn't it logical to detect whether something is beyond logic or not?
This is why avoiding cognitive biases is fundamentally part of establishing something logically, even if it cannot be understood by logical rules.
A simple example: logic cannot comprehend the logic behind a magic show, even though the magic show is logical; our perception is simply biased (blurred - obscured).
Here, ensure first that we are not dealing with a magic show (except for magicians who have already overcome cognitive biases and are creating the scenario of cognitive bias themselves).
Once it is certain that we are not dealing with a magic show, then proceed to apply all the logical formulas you know. It is better to deepen reasoning through the Quran, which recognizes a broader range of causality than what is limitedly known in philosophy.
Justified Cognitive (Tested Perception)
So, our focus here is on overcoming cognitive biases, so that the conclusion-drawing process (logically) is also relevant and not out of context.
So, besides understanding the signs of logic (logical fallacy), it is also necessary to understand the signs of perception (justified cognitive to avoid cognitive biases) so that perception is not deceived like a magic trick.
These are some forms of justification which have not yet been specifically realized by philosophy except in a psychological context, not yet in its own philosophical realm.
Here, we will transform the concept of philosophy, which tends to be considered abstract, into a philosophy that is objective without ignoring the subjective side (note here the importance of synergy between subjectivity & objectivity).
Every word or piece of meaning must have empirical evidence.
📌 Case Study:
Example: "fruit on the table". The empirical evidence (seeing more closely the presence of fruit on the table). If not found, then...
✅ EXAMPLE - Exemplar Justification.
Find an example that there has been fruit on the table before. If there is no example at all of fruit on the table, then..[.
✅ SCALE - Scale Justification
Look for a smaller scale. Maybe it means a picture of fruits? Plastic fruit? Or something resembling fruit (synthetic fruit). If there is no empirical evidence, nor an example & scale, then...
✅ LOGICAL CONSEQUENCE - Consequence Justification.
Look for the logical consequence of the possibility of the table's surface and material being able to hol[d fruit.
✅ TRACE - Trace Justification.
Ensure there are traces, smell, stickiness from the sweetness of fruit that was once placed on the table. Traces of people talking about fruit on the table. LIKE A PHILOSOPHICAL DETECTIVE.
📌 If it has been proven that there is fruit on the table in any form of justification above, it is only ensuring the state is free from obscurity. However, further justification is needed so that the information "there is fruit on the table" is not wrongly linked to another statement "there is a sweetheart sitting on the table."
✅ CAUSAL JUSTIFICATION. The point is to be aware that the statements that have been verified because our perception is tested through justification (justified cognitive), should not overlap with other information. Here, "Causal Justification" is necessary.
To determine which type of causality applies to "the fruit on the table." In this case, it falls under the type of "dependent reliance."
👉 For philosophers who find the dependent causality relationship strange, they are late to the understanding of Einstein or science, which has grasped this concept where Einstein's theory of gravity emphasizes the Earth's reliance on space.
🔰 See how understanding causality enables us not only to touch reality but also to separate events or states according to their type, to prevent overlapping between Einstein's gravity and Newton's gravity model. | seremonia |

在当前社交媒体充斥着各种内容的时代，Reddit作为一个知识分享和社区讨论的平台，吸引了无数用户的关注和参与。然而，随着Reddit的用户群体不断扩大，许多人开始寻求提升自己帖子的可见性和影响力的方法。这就导致了一些用户使用Reddit加粉软件来增加其粉丝数量和帖子的点赞数，以此来提高其在社区中的影响力和知名度。
Reddit加粉软件通常被设计为自动化工具，可以快速地增加用户的粉丝数和帖子的点赞数。这些软件可能通过机器人账号自动订阅其他用户、自动点赞帖子，甚至自动发布评论，以制造看似真实的互动和活跃度。尽管这些工具表面上看起来可以帮助用户获得更多的曝光和社区认可，但实际上它们却带来了一系列潜在的问题和负面影响。
首先，Reddit作为一个注重真实互动和有价值内容的社区平台，对于机器人和虚假活动持有零容忍的态度。使用加粉软件往往违反了Reddit的使用政策，可能导致用户的账号被封禁或被限制使用，从而带来严重的法律和道德责任问题。
其次，通过加粉软件增加的粉丝和点赞往往是虚假的，缺乏真实的互动和价值。这种人为的干预不仅可能误导其他用户，也会扭曲社区的真实反馈和评价体系，最终损害了整个社区的信誉和用户体验。
最重要的是，使用Reddit加粉软件不符合正当的社交媒体使用伦理和原则。在任何社交媒体平台上，真实的互动和内容质量才是长期成功和影响力的关键，而不是依赖于虚假的粉丝和点赞数。
因此，作为一个Reddit用户，应当遵守平台的使用规则和道德准则，注重创造有价值的内容和真实的社区互动。通过真诚和努力，才能在Reddit这样的社交媒体平台上建立起真正的影响力和声誉，获得长远的成长和回报。

## Intro
Lately, I had a chance to try out the API-First design approach. I had never written an OpenAPI document before, so I had no real knowledge of its benefits. It always seemed like too much prep work.
As developers, we often prefer writing code to writing documentation. We dive straight into coding, eager to see our project in action. However, I recently discovered a game-changing approach that has transformed my development process: API-First design. In this post, I'll share my experience implementing this method in a full-stack hobby project, highlighting how it streamlined my workflow and why it's worth considering for your next side project.
> tl;dr: **It will force you to think about your users and how they use your API before writing any code.**
I’ve been working on a full-stack hobby project where my backend and frontend use different languages (Go and SvelteKit). I decided to give this approach a try and had my **“aha” moment**. I wish I had done it before.
## Prioritizing Your Application's Foundation
The API is how we are going to expose our app functionality. An API-first design approach prioritizes the development of APIs before implementing other parts of a software system (or writing code). This method focuses on creating a well-designed, consistent, and user-friendly API that is the foundation for the entire application.
This methodology places the API at the center of the development process, treating it as a first-class citizen rather than an afterthought. Your API comes first, then the implementation.
With a written API specification, we can leverage code generation tools to create some boilerplate code. By defining objects in the specification, code-gen tools can generate the relevant structs, for both the frontend and backend (yes, even when the language used is different). This is a big time saver and it helps us to be consistent.
## What is Open API?
“***The OpenAPI Specification*** *(OAS) defines a standard, language-agnostic interface to RESTful APIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code, documentation, or through network traffic inspection*.”
Simply put, it’s a **contract** that describes your API types and endpoints. You list all your API endpoints, their HTTP methods, what they possibly return, and some description of what they do.
*Now, what if I told you, you can use this document to improve and accelerate your dev experience?*
Once I had this document, that describes the contract between my API server and its clients, these are the things I could do:
1. Generate my backend types (Go)
2. Generate my frontend types (Typescript)
3. Generate a client code for my server (also Typescript)
4. Generate a testing client with Insomnia or Postman
This is a lot of boilerplate code I could save myself from writing. It ensures the frontend and backend types are synchronized since both are generated.
Grab a 🍺, and let’s walk through an example.
## The Project Structure
We will be using Go for the backend and some JS framework for the frontend, and a simple structure would look like:
```bash
app/
├─ api/ -- the place for the Swagger OpenAPI document
├─ client/ -- the client-side code
├─ cmd/
│ ├─ app.go -- thin main func that runs our API server
├─ internal/
│ ├─ api/
│ │ ├─ main.go -- for code-gen
│ ├─ users/
│ │ ├─ handlers.go -- implements the API contract
```
## Generate The APIs
Let's create our API specification. It includes two endpoints and two structs: User and Error.
Place this file under your `/api` directory
```yaml
openapi: 3.0.3
info:
title: Devopsian OpenAPI Example
version: 0.1.0
contact:
name: dev
url: https://devopsian.net
servers:
- url: "http://localhost/v1"
components:
schemas:
Error:
type: object
required:
- code
- message
properties:
code:
type: integer
format: int32
message:
type: string
User:
type: object
required:
- id

properties:

default:

$ref: "#/components/schemas/Error"
/signup:

responses:

content:

$ref: "#/components/schemas/User"
default:

content:

requestBody:
required: true
content:
application/json:
schema:
type: object
properties:
name:
type: string
email:
type: string
format: email
```
## Generate Server-Side Code
To generate the server-side code, we need some library. I found [oapi-codegen](https://github.com/oapi-codegen/oapi-codegen) for that. It supports many popular HTTP libraries (echo, gin, etc.) At the time of writing, I used `oapi-codegen@v2.3.0`
Add the following files to your `/internal/api` directory
```go
// /internal/api/main.go
//go:generate oapi-codegen --config cfg.yaml ../api/openapi3.yaml
package api
// make sure to install:
// go install github.com/oapi-codegen/oapi-codegen/v2/cmd/oapi-codegen@v2.3.0
```
```yaml
# /internal/api/cfg.yaml
package: api
output: server.gen.go
generate:
models: true
echo-server: true
```
I’m using the echo web framework, you can browse the library documentation to use other frameworks. Now run `go generate ./...` and it will generate the interfaces (handlers) your web server has to implement to **fulfill** this contract, including the **types**.
### Interface Implementation
Now it’s time to write the implementation. We create a `users` package where all the user's API handlers, business logic, storage, etc. are defined. We will keep it simple and implement the handlers with static content.
```go
type UsersHandler struct {
DB *sql.DB
}
func (u *UsersHandler) GetUser(ctx echo.Context) error {
// load the user from the database and return it to the caller
return ctx.JSON(http.StatusOK, api.User{
Email: types.Email("demo@devopsian.net"),
Name: "DemoUser",
Id: "1",
})
}
func (u *UsersHandler) PostSignup(ctx echo.Context) error {
var body api.PostSignupJSONBody
if err := ctx.Bind(&body); err != nil {
return ctx.JSON(http.StatusBadRequest, api.Error{Code: http.StatusBadRequest, Message: "invalid request"})
}
// save user in database
return ctx.NoContent(http.StatusOK)
}
func New(db *sql.DB) *UsersHandler {
return &UsersHandler{DB: db}
}
```
Next, we need to create our web server entry point, we define that at `cmd/server.go`
```go
type Server struct {
users.UsersHandler
}
func main() {
e := echo.New()
s := Server{UsersHandler: *users.New(nil)}
api.RegisterHandlers(e, &s)
e.Logger.Fatal(e.Start(":8080"))
}
```
Note I explicitly pass in `nil` as DB implementation for this example, because we don’t use it.
That’s it. If the code compiles, *our server implements the API contract.* All the API endpoints are handled by the spec. If I had missed something, **it would have broken at compile time.**
How nice is that?
## Generate a Typescript Client
It’s time to generate a client for our API. We use the same openapi schema file to generate a JS client. I won’t include a full frontend project in this example, but rather show how you can generate a client to an existing one.
In the `client/` directory, install the [code-generation](https://www.npmjs.com/package/openapi-typescript-codegen) tool for JS:
`npm install openapi-typescript-codegen --save-dev`. (This post was tested with v0.29.0)
Create a `client/api/` directory, and let’s run the tool:
`npx openapi-typescript-codegen --input ../api/openapi3.yaml --output api/ --name ApiClient`.
This will generate a bunch of typescript files. To use our client we need to create an instance of it.
```typescript
// api.ts
import { ApiClient } from './api/ApiClient'
const client = new ApiClient().default
// client has all the methods of our API:
// - getUser()
// - postSignup(requestBody: {name?: string, email?: string})
```
That's it.
## Summary
API-First design isn't just another development buzzword—it's a powerful approach that can significantly enhance your side projects.
By prioritizing your API design before implementation, you gain clarity, consistency, and efficiency.
The OpenAPI specification is a **contract** between your frontend and backend, **enabling automatic code generation** for types, clients, and even testing tools.
This approach not only saves time but also ensures better synchronization between different parts of your application.
While it may seem like extra work upfront, the long-term benefits—including improved development speed, reduced errors, and better API documentation—make it a valuable investment for any side project.
If you haven't tried it yet, now might be the perfect time to give it a shot and experience these benefits firsthand.

In your `script.js` file, add JavaScript code to make your YouTube homepage interactive with features like a collapsible sidebar and theme toggling.
```javascript
const menuButtons = document.querySelectorAll(".menu-button");
const screenOverlay = document.querySelector(".main-layout .screen-overlay");
const themeButton = document.querySelector(".navbar .theme-button i");
// Toggle sidebar visibility when menu buttons are clicked
menuButtons.forEach(button => {
button.addEventListener("click", () => {
document.body.classList.toggle("sidebar-hidden");
});
});
// Toggle sidebar visibility when screen overlay is clicked
screenOverlay.addEventListener("click", () => {
document.body.classList.toggle("sidebar-hidden");
});
// Initialize dark mode based on localStorage
if (localStorage.getItem("darkMode") === "enabled") {
document.body.classList.add("dark-mode");
themeButton.classList.replace("uil-moon", "uil-sun");
} else {
themeButton.classList.replace("uil-sun", "uil-moon");
}
// Toggle dark mode when theme button is clicked
themeButton.addEventListener("click", () => {
const isDarkMode = document.body.classList.toggle("dark-mode");
localStorage.setItem("darkMode", isDarkMode ? "enabled" : "disabled");
themeButton.classList.toggle("uil-sun", isDarkMode);
themeButton.classList.toggle("uil-moon", !isDarkMode);
});
// Show sidebar on large screens by default
if (window.innerWidth >= 768) {
document.body.classList.remove("sidebar-hidden");
}
```

Users participate anonymously, choose a circulation period of 1 to 28 days, and obtain different yields. For example, if you invest 10,000 USDT, you will earn 10,040 USDT after 1 day and 12,400 USDT after 28 days. BitPower incentivizes sharing and promotion, and you can get up to 17 levels of sharing rewards. If a user circulates 100 USDT, he can get 20% of the first generation of friends' income. If he circulates 1,700 USDT, he can get 1% of the 17th generation of friends' income. Each reward is automatically returned to the initiator's wallet to ensure timeliness and security. BitPower not only provides returns far beyond traditional finance, but also ensures transparency and fairness through smart contracts. It is the only choice for blockchain investment. | _32d1554462535885b588b | |

# How to create a screen recorder in JavaScript
In this article, we will build a simple screen recording application using JavaScript, leveraging the MediaStream and MediaStream Recording APIs. You will learn to capture, record, and download your screen recordings. Here is a preview of what we will be building:
## Understanding the MediaStream and MediaStream Recording APIs
MediaStream and MediaStream Recording APIs are part of the web APIs provided by browsers. They enable developers to perform various tasks from within the browser. Check out the [official documentation](https://developer.mozilla.org/en-US/docs/Web/API) for a complete list of available web APIs.
### MediaStream API
The MediaStream API provides the interfaces and methods for working with streams and their constituent tracks. One such interface is the `mediaDevices` interface, which provides access to connected audio and video sources like webcams, microphones, and screens through its `getUserMedia` and `getDisplayMedia` methods.
The `getUserMedia` and `getDisplayMedia` methods access audio and video streams from a user’s device when the user grants permission. The difference between the two methods is in the source of their streams. The `getUserMedia` method accesses streams from user-facing media inputs like webcams or microphones. Meanwhile, the `getDisplayMedia` method accesses video and audio streams from the user's device.
### MediaStream Recorder API
The MediaStream Recording API makes it possible to record the data generated by a [`MediaStream`](https://developer.mozilla.org/en-US/docs/Web/API/MediaStream). The `mediaStream` represents a stream of media content. The mediaStream Recording API provides a single `mediaRecorder` interface for recording media. To control recording, the `mediaRecorder` uses events like start, pause, resume, and stop. It also has an `ondataavailable` event. This event triggers a [`BlobEvent`](https://developer.mozilla.org/en-US/docs/Web/API/BlobEvent), which creates a [`blob`](https://developer.mozilla.org/en-US/docs/Web/API/Blob) from the available data.
## Setting up your Screen Recorder
Now that we have a basic understanding of the mediaStream and mediaStream Recording APIs, let's use this knowledge to create a simple screen recording application.
### Building the User Interface
The first step is to create a user interface for our application. To follow along, create a new project with three new files: `index.html`, `style.css`, and `main.js` in it. Next, copy and paste the below markup into the `index.html` file:
```html
<p class="countdown" id="countdown"></p>
<div class="screen-recorder">
<h1>Capture your screen</h1>
<video controls preload="metadata" id="video"></video>
<div>
<button type="button" class="btn" id="btn">Start Recording</button>
<a href="" class="btn" id="link">download video</a>
</div>
</div>
```
This markup sets up the layout of our page. The video element will display the recorded video. The `p` element with a class of `countdown`, will display a countdown before the recording starts. You should see the below image in your browser when you save the file:
![A screenshot showing the page layout]
https://blog.openreplay.com/images/create-a-screen-recorder-with-javascript/images/image3.png
Next, copy and paste the below styles into your `style.css` file:
```css
* {
padding: 0;
margin: 0;
box-sizing: border-box;
}
body {
width: 100vw;
min-height: 100vh;

### Accessing Screen and Audio Streams
Now that we have built our user interface, it is time to request access to the user’s media devices. First, let's create new variables that will be reassigned later, and also obtain references to the button and anchor elements.
```javascript
const startBtn = document.getElementById("btn");
const downloadLink = document.getElementById("link");
let blob = null;
let videoStream = null;
```
Due to [security reasons](https://developer.mozilla.org/en-US/docs/Web/Security/User_activation), we can only request access to a user's media devices when they actively interact with our website, such as by clicking a button. Let's proceed by adding a callback function that will be triggered when the user clicks on the `startBtn`:
```javascript
startBtn.addEventListener("click", startScreenCapturing);
```
Next, we will define the `startScreenCapture` function:
```javascript
async function startScreenCapture() {
if (!navigator.mediaDevices.getDisplayMedia) {
return alert("Screen capturing not supported in your browser.");
}
try {
if (!videoStream?.active) {
videoStream = await navigator.mediaDevices.getDisplayMedia({
audio: true,
surfaceSwitching: "include",
});
const audioStream = await navigator.mediaDevices.getUserMedia({
audio: {
echoCancellation: true,
noiseSuppression: true,
sampleRate: 44100,
},
});
const audioTrack = audioStream.getTracks()[0];
videoStream.addTrack(audioTrack);
recordStream(videoStream);
} else {
throw new Error(
"There is an ongoing recording. Please, stop it before recording a new one"
);
}
} catch (error) {
console.error(error);
alert(error);
}
}
```
The `startScreenCapturing` function initiates the screen-capturing process. First, it verifies browser compatibility by checking for the availability of the `getDisplayMedia` method. If supported and there are no active streams, it requests access to the user's internal audio and screen streams through the `getDisplayMedia` method. The `getUserMedia` requests and provides access to the external audio. It then combines the audio and video streams by adding the `audioTrack` from the audio stream to the video stream, creating a single stream. Finally, it calls the `recordStream` function to manage the recording process. Any errors encountered during this process are logged and the user is alerted. The GIF below illustrates what happens when you save the file and click on the `startBtn`:
### Recording the stream
Now that we have available streaming data, we will use the MediaStream Recording API to record these streams. Let's define the `recordStrem` function that handles the recording:
```javascript
function recordStream(stream) {
countDown();
const mediaRecorder = new MediaRecorder(stream, {
mimeType: "video/webm; codecs=vp8,opus",
});
const recordedChunks = [];
mediaRecorder.addEventListener("dataavailable", (e) =>
recordedChunks.push(e.data)
);
}
```
The `recordStream` function calls the countdown function and creates a new `MediaRecorder` instance. This instance is configured to record the captured stream in `Webm` format with `VP8` video and `Opus` audio [codecs](https://developer.mozilla.org/en-US/docs/Glossary/Codec). Next, the `recorderChunks` array is created to hold the recorded data.
An event listener is attached to the `mediaRecorder` to listen for the `ondataavailable` event. This event is triggered when stream data becomes available. The stream data is then pushed into the `recorderChunks` array.
Next, let's define the `countdown` function:
```javascript
function countdown() {
const countDownElement = document.getElementById("countdown");
countDownElement.style.display = "grid";
let count = 3;
function reduceCount() {
countDownElement.textContent = count;
count--;
if (count >= 0) {
setTimeout(reduceCount, 1000);
} else {
countDownElement.style.display = "none";
}
}
reduceCount();
}
```
The `countdown` function creates a visual countdown for 3 seconds before recording. It selects the HTML element with the class `countdown` and updates its text content with the remaining time each second. Once the countdown reaches zero, the element is hidden, allowing the user to know when the recording starts.
### Managing the Recording
Having set up the recording, we need to start the `mediaRecorder` and the user should also be able to stop the recording. Let's edit the `recordStream` function to include these functionalities:
```javascript
function recordStream(stream) {
// Existing codes
// Stop recording and audio streaming when video streaming stops
stream.getVideoTracks()[0].addEventListener("ended", () => {
mediaRecorder.stop();
stream.getAudioTracks()[0].stop();
});
mediaRecorder.addEventListener("stop", () => {
createVideoBlob(recordedChunks);
showRecordedVideo(blob);
});
setTimeout(() => mediaRecorder.start(), 4000);
}
```
In the above code, an event listener is attached to the video track of the ongoing stream being captured to detect when it ends. The event will be triggered when this button is pressed:
When this event occurs, it stops the recording and audio streaming. An event listener is also attached to the `mediaRecorder` to listen for the stop event. Once this event is triggered, it executes the `createVideoBlob` and `showRecordedVideo` functions. The `mediaRecorder` is then started after a delay of 4 seconds. This allows the `countdown` function to finish executing before the recording starts. The below GIF illustrates what should happen when you save the file and click the `startBtn`:
### Displaying the recorded video
With the user's screen now being captured and recorded, they should be able to see their video when they stop recording. To achieve this, let's define the `createVideoBlob` and the `showRecordedVideo` functions:
```javascript
function createVideoBlob(recordedChunks) {
blob = new Blob(recordedChunks, {
type: recordedChunks[0].type,
});
}
function showRecordedVideo() {
const video = document.getElementById("video");
video.src = URL.createObjectURL(blob);
calculateVideoDuration(video);
}
```
In the `createVideoBlob` function, our global `blob` variable is reassigned to the newly created Blob object using the `Blob()` constructor. This `Blob` is constructed from the `recordedChunks` array, representing chunks of recorded video data. The constructor also includes an options object specifying the MIME type of the `Blob`, derived from the MIME type of the first recorded chunk in the array.
In the `showRecordedVideo` function, a reference to the video element is created. Its `src` attribute is then set to a URL created using the `createObjectURL` method of the `URL` interface, linking the recorded video data to the video element for playback. Now, when a user stops recording, it will be displayed in the video element:
Looking at the above GIF carefully, you will notice that the video has no duration before it starts playing. The duration is only shown when the video is already playing. [This is because of a bug in browsers that sets an incorrect duration on the recorded media.](https://issues.chromium.org/issues/40482588) To fix the error, we will define a new function `calculateVideoDuration` that sets the correct duration for us:
```javascript
function calculateVideoDuration(videoElement) {
videoElement.addEventListener("loadedmetadata", () => {
if (videoElement.duration === Infinity) {
videoElement.currentTime = 1e101;
videoElement.addEventListener(
"timeupdate",
() => {
videoElement.currentTime = 0;
},
{ once: true }
);
}
});
}
```
The `calculateVideoDuration` function sets the correct duration by setting up an event listener on the provided `videoElement`. When the video metadata is loaded, it triggers the `loadedmetadata` event, which executes a function that checks if the video duration is `Infinity`, indicating that the video duration could not be determined correctly. If so, it sets the `currentTime` to a larger value `1e101`. When the browser attempts to set the `currentTime` to this large value, it recalculates the actual duration of the video. The subsequent `timeupdate` event ensures that this recalculated duration is captured and the current time is reset to the start of the video. This workaround ensures that the video's `duration` property is updated correctly from `Infinity` to its actual duration.
Next, let us call the function in the `showRecordedVideo` function and pass the video element as its argument:
```javascript
function showRecordedVideo() {
// Previous codes
calculateVideoDuration(video);
}
```
Now, when we record a video, we should be able to see its correct duration:
### Downloading the Recorded Media
To download the recorded media, we can use the `createObjectURL` method of the `URL` to create a temporary URL for the recorded Blob:
```javascript
downloadLink.addEventListener("click", () => {
downloadLink.href = URL.createObjectURL(blob);
const fileName = prompt("What is the name of your video?");
downloadLink.download = `${fileName}.webm`;
downloadLink.type = "video/webm";
});
```
This code handles clicking the download link for the recorded video. Clicking the download link, triggers the creation of a temporary `URL` for the video data stored in the `blob`. This `URL` allows the browser to access the video for download and is set as the `href` of the download link. The user is then prompted to enter a file name for the recorded video. The chosen name is combined with the `.webm` extension and assigned to the download link's `download` attribute, to be used as the file name when downloaded. The link's `type` is then set to `video/webm` to inform the browser of the file type. When you save the file and check your browser, everything should work as expected:
## Conclusion
This article provided a basic understanding of MediaStream and MediaStream Recording web APIs and their components. It has effectively demonstrated how to capture screen and audio streams, manage recordings, download recordings, and address the common bug of incorrect duration display in recorded videos. While the example presented is simplified, the knowledge gained from this guide can serve as a strong foundation for building feature-rich screen recording applications.

You might not think about hills. The [Emerald City is built on seven hills](https://www.historylink.org/File/4131?ref=blog.gitguardian.com), though 'hill' is an understatement. This elevation helped early settlers stay dry and safe from the waves of Puget Sound while giving them a firm foundation for their houses. Like our brave ancestors, hundreds of security professionals gathered in Seattle to build a firm foundation and elevate their knowledge around securing applications at CloudNativeSecurityCon 2024!
This was the second-ever CloudNativeSecurityCon held at the brand-new [Summit addition to the Seatle Convention Center](https://seattleconventioncenter.com/venues/summit-addition?ref=blog.gitguardian.com). Dozens of speakers shared their knowledge and experience building cloud-native applications and stories about challenges they have faced along the way. There were workshops, a capture-the-flag experience, and, of course, the hallway track, where the community really connects. Throughout it all, there was a real sense of urgency that we must work together to face the rapidly evolving threats we all face around authentication and authorization without using long-lived credentials.
It would be impossible to capture the true spirit and all the learnings of this event. Here are just a few highlights.
Better security can mean less development work
----------------------------------------------
In her opening keynote, "Demystifying Secure Application Communication with Zero Trust: Identity, Integrity, Confidentiality," [Lin Sun, Head of Open Source at solo.io](https://www.linkedin.com/in/lin-sun-a9b7a81/?ref=blog.gitguardian.com), demonstrated the toil a developer needs to go through when manually implementing Mutual Transport Layer Security (mTLS) and then shared a better approach. When thinking through how our machine identities communicate, it all boils down to being about to prove they are allowed to connect. We can do this in a number of ways, but everyone agrees that long-lived credentials are a terrible approach.
Instead of just discussing the theory of securing an application, she opened a code editor and began building an app and the tedious steps of implementing mTLS. There is a lot to keep track of when implementing such a solution, accounting for it in the client and the server, requiring a lot of manual configuration. Then, with a lot less fuss, she implemented SPIFFE with Istio, without sidecars. This is a way to give every entity a unique ID, allowing services to request short-lived, just-in-time certificates to enable communication. It was startling to see how fast she could achieve secure communication with just a few minor app changes, making for a much more attractive dev experience.

Demystifying Secure Application Communication with Zero Trust: Identity, Integrity, Confidentiality
What's so hard about logging in?
---------------------------------
In their presentation "Learn to Navigate the Perils and Pitfalls of Multi-Tenant Identity Infrastructure," Zitadel's [Co-Founders Fabienne Bühler](https://www.linkedin.com/in/hifabienne/?ref=blog.gitguardian.com) & [Livio Spring](https://www.linkedin.com/in/liviospring/?ref=blog.gitguardian.com) asked an alarmingly simple question: How hard is it to secure a login process. After all, there are only two fields: username and password. The reality is that underneath this simple interface, there is a whole hidden iceberg of challenges and competing technologies that all need to be considered, making this one of the more complex security challenges we face.
What kind of MFA should you use? Will you allow OpenID Connect? What about passwordless approaches like FIDO2-compliant solutions or biometrics? That is a lot to consider for a single user on a single app. Now multiply that set of decisions by all the types of users, such as internal staff, admins, end users, etc. Again, multiply this complexity across all your applications...it is easy to see this is a seriously large and complex concern.
While Fabienne and Livio did not offer a silver bullet, they did lay out a simple framework for evaluating solutions. In their opinion, solving the multitenancy user authentication issue came down to a question of "Shared" vs. "Dedicated" system approaches. Each approach involves a trade-off of costs, management complexity, performance, and isolation. Ultimately how you secure your multi-tenant applications is going to depend on the budgets and organizational goals unique to you.

Documentation quality as a leading indicator for revenue and customer satisfaction
----------------------------------------------------------------------------------
You might not have documentation on your list of ways to track your organization's productivity, but it likely should be on there. In her data-filled presentation "Amplifying Impact: Documentation and Supply Chain Security," [Michelle Irvine, Technical Writer at Google Cloud and contributor to the DORA project](https://www.linkedin.com/in/michelle-irvine-b7bb2b3b/?ref=blog.gitguardian.com), showed that this is an important metric to consider. Even though there is not much immediate feedback from documentation, especially internal documentation, teams that get this aspect right have less burnout and are much more productive.
Using the research methodologies from the [DORA program](https://dora.dev/?ref=blog.gitguardian.com), Michelle cited eight attributes by which they evaluated documentation:
- Reliable (Functional)
- Clear
- Findable
- Comprehensive
- Organized
- Up-to-date
- Accurate
- Relevant
[According to DORA research](https://cloud.google.com/blog/products/devops-sre/deep-dive-into-2022-state-of-devops-report-on-documentation?ref=blog.gitguardian.com), the evidence is clear: security drives organizational performance and lower burnout across teams. In terms of security alone, the teams with the best document quality were 451% better than average at supply chain security. While building and maintaining exceptional documentation takes time, the value of undertaking such an effort is clear. Michelle urged us to focus on document quality over quantity, as endlessly sifting through too many docs is also a problem to avoid.

Amplifying Impact: Documentation and Supply Chain Security
A full plate of security lessons
--------------------------------
In his food-themed session, "A Mouthful of Mayhem: Taste Test and Gut Response to SLSA, GUAC, and Supply Chain's Plat Du Jour," [Shane Lawrence, Sr Staff Security Developer at Shopify](https://www.linkedin.com/in/shaneplawrence?ref=blog.gitguardian.com) walked us through what some of the latest industry terms mean with some dining analogies. He quoted computing science legend [Ken Thompson](https://en.wikipedia.org/wiki/Ken_Thompson?ref=blog.gitguardian.com) in order to sum up the problem set: "You can't trust code that you did not totally create yourself. (Especially code from companies that employ people like me.)" He said that in 1983; the problem has only gotten worse since, with over 245,000 malicious packages discovered in 2023 alone.
Just as we want to read the list of ingredients for our food, the Software Bill of Materials (SBOM) gives us the list of components that make up our applications. Supply-chain Levels for Software Artifacts (SLSA) verifies that the proper instructions were followed to create our applications, similar to how a health department certifies a restaurant is following the right policies when making our food.
CVEs are like warnings from the FDA for food recalls and public health warnings. He argued that SBOMs should not include vulnerabilities, the same way ingredient lists don't need to warn you about E. Coli outbreaks. Finally, the project Graph for Understanding Artifact Composition (GUAC) is a way to visualize the data around SLSA and SBOMs in a more digestible way, helping surface what really matters to your critical systems in a queriable framework.

A Mouthful of Mayhem: Taste Test and Gut Response to SLSA, GUAC, and Supply Chain's Plat Du Jour
Building the future of Cloud Native Security together
-----------------------------------------------------
One of the main things that stood out at CloudNativeSecurityCon this year was that the future of security is all of our responsibility, no matter your role. Your author was able to give a talk, one of many at this event, about [scaling security through security champion programs](https://sched.co/1dCUi?ref=blog.gitguardian.com). The trend is becoming clear: we can't relegate security to another department late in the process. We must shift to having pervasive security, shifted left, down, right, and all throughout our organizations.
This spirit of cooperation in solving security issues for all is present not just in internal teams but across the wider security community. It really stands out in the open source space in projects like OpenSSF and the Cloud Native Computing Foundation. This is evidenced by the amount of work being done to bring Vulnerability Exploitability eXchange (VEX) tooling into existence and helping the wider community adopt it. Ultimately, all of these projects boil down to people working together for the greater good. It is a very good thing that we have opportunities to get together to have the needed conversations to drive this cooperation at events like CloudNativeSecurityCon. | dwayne_mcdaniel |

Manual testing is a process to test the application manually without using any software. Application tested manually by humans to ensure the performance.
2. Advantages
A. Identifying the bugs
B. Flexibility in testing process to changes the test cases.
C. Easier to learn new tester
Disadvantages
A. Manual testing takes more time.
B. High labour cost
C. To stop manual human testing errors.
For Example
In Amazon website, to select a product to purchase page, we need to check the customer requirement, seller requirement, display of a page, options in pages, compare the product all are tested by the tester if it works fine or not. Manual testing takes more time to check all pages interface and check again & again the same process. Automatic testing is reduce the time to check the pages again & again. Easily to identify the bugs. | tamizh | |

While the need for mobile applications is increasing, it is upon developers today to create applications that are not only rich in features but also strong and updated. That is where [Flutter](https://flutter.dev/), which is [Google’s](https://www.google.com.ng/) open-source UI toolkit, comes into play as it gives full answers for you when developing cross-platform apps using the same codebase.
This article is geared towards securing and keeping Flutter applications current. Adherence to these procedures will ensure that one’s personal information is secure. Furthermore, it underscores the need for frequent software modifications to enhance effectiveness and eliminate any errors that might arise, as well as testing on various versions to avoid losing relevance with time. Developers can be sure of the reliability of their products if they follow these rules while also protecting them from being hacked because developers could hack into someone else’s creation, thereby causing their career harm if their application falls into unscrupulous hands.
## Hashing vs. Encryption
Hashing is an important way to protect information and has different aspects compared to encryption, which is used to conceal plaintext. A Flutter application needs safeguarding—this section contains detailed information on how these compare.
### Hashing
We use hashing to know that data has not been tampered with and to verify data. Simply put, hashing turns the data into a unique size fixed normally represented by a digest string of characters. Hash functions have no reverse functions. Once the data is hashed, one cannot convert it back to the initial form. They return a uniform length result irrespective of how long the input size may be to ensure that the hash output is consistent. It’s deterministic such that any given input will always generate similar hashes.
Hashing algorithms are meant to be speedy and effective, thus facilitating rapid calculations. A good hash function also reduces the chances of two different inputs producing similar hash outputs.
To securely preserve email passwords, save them to the database as hashes first. Then, make sure data has not been altered based on how different instances of this data compare with themselves in terms of their hashes on those instances. This is done by using digital signatures to confirm whether a given set of information has been interfered with or not.
Popular Algorithms include:
- [MD5](https://en.wikipedia.org/wiki/MD5) (though it is now considered weak and not recommended)
- [SHA-256](https://en.wikipedia.org/wiki/SHA-2)
- [SHA-3](https://en.wikipedia.org/wiki/SHA-3)
### Encryption
Encryption protects data confidentiality by transforming data into an alternative format only authorized persons can decipher back to the original form. Encryption algorithms are functions that can work in both directions; therefore, encrypted data can be decrypted if the right key is available. Usually, the size of encrypted data differs from the source one. A decoder uses characters to decrypt this formatted information.
Encryption is used to keep things a secret; hence, when the data is intercepted, anyone cannot understand it without a certain key. Make sure you encrypt your data anytime you send it through a network so that other people can't pick it up. As a preventive measure, protecting sensitive information on disks or any other storage devices from unauthorized access is essential. There must be secure messaging services and tamper-proof messaging mechanisms for secure communication.
Popular Algorithms include:
- [AES](https://en.wikipedia.org/wiki/Advanced_Encryption_Standard) (Advanced Encryption Standard)
- [RSA](https://en.wikipedia.org/wiki/RSA_(cryptosystem)) (Rivest-Shamir-Adleman)
- [ECC](https://en.wikipedia.org/wiki/Elliptic-curve_cryptography) (Elliptic Curve Cryptography)
### When do I use Hashing?
Passwords should be kept securely using employing hashing (salt included). Hash functions such as [bcrypt](https://www.npmjs.com/package/bcrypt) or [Argon2](https://www.npmjs.com/package/argon2) were crafted particularly to hash passwords, hence providing extra security mechanisms such as key stretching. Hashing was also applied to confirm the integrity of the locally stored or fetched data from the server.
### When do I use Encryption?
Encrypting sensitive data being sent over a network is fundamental. As an illustration, [HTTPS](https://en.wikipedia.org/wiki/HTTPS) (which is reliant on [TLS](https://en.wikipedia.org/wiki/Transport_Layer_Security) encryption) guarantees data encryption while it’s being transmitted. Moreover, sensitive data saved in the gadget should be encrypted to keep it away from unauthorized individuals. Encrypting sensitive data with [flutter_secure_storage](https://pub.dev/packages/flutter_secure_storage) helps users control it.
### Verdict
Flutter applications' security heavily relies on how different roles perform hashing and encryption. Hashing is used to guarantee the integrity of data and securely store passwords. Data must be encrypted to ensure that it is confidential when in transit or stored.
Adopting a comprehensive measure toward security would aid in safeguarding an application from a vast array of threats. For example, one can encrypt transmitted information and store secure passwords through hashing. It's usually important to combine both methods.
## Implementing Password Hashing in Flutter
To perform password hashing in the context of a Flutter app, a software developer can utilize a [crypto](https://pub.dev/packages/crypto) package. The following code snippet shows us how we can encrypt our regular plain text passwords which is a critical aspect when working with user authentication systems in modern web applications.
### The Process
The first thing you need to do is to add the `crypto` package to your `pubspec.yaml` file:
```yaml
name: your_project_name
description: A new Flutter project.
publish_to: 'none' # Remove this line if you wish to publish to pub.dev
version: 1.0.0+1
environment:
sdk: ">=2.17.0 <3.0.0"
dependencies:
flutter:
sdk: flutter
crypto: ^3.0.1
dev_dependencies:
flutter_test:
sdk: flutter
flutter:
uses-material-design: true
```
You must replace `your_project_name` with what you have named your project. This file contains the required `crypto` packager version `^3.0.1` and normal Flutter dependencies.
The following is what includes the hash and verification functions that use [dart:convert](https://api.dart.dev/dart-convert/dart-convert-library.html) and [crypto](https://pub.dev/packages/crypto) packages in Dart:
```dart
import 'dart:convert';
import 'package:crypto/crypto.dart';
// Function to hash the password
String hashPassword(String password) {
var bytes = utf8.encode(password); // Convert password to bytes
var digest = sha256.convert(bytes); // Hash using SHA-256
return digest.toString(); // Convert the digest to a string
}
// Function to verify the password
bool verifyPassword(String enteredPassword, String storedHash) {
var enteredHash = hashPassword(enteredPassword); // Hash the entered password
return enteredHash == storedHash; // Compare the hashes
}
void main() {
// User registration: hashing and storing the password
String password = "password";
String hashedPassword = hashPassword(password);
print("Password successfully hashed and stored: $hashedPassword");
// User authentication: verifying the password
String enteredPassword = "password";
bool isPasswordCorrect = verifyPassword(enteredPassword, hashedPassword);
print("Password is correct: $isPasswordCorrect");
}
```
Explanation:
* Import Packages: `dart:convert` is employed for encoding passwords into bytes. `crypto` is used to hash passwords using SHA-256.
* `Hash_Password` Function (hashPassword): Encodes password into bytes using UTF-8 encoding. Hash the bytes using SHA-256. Turn hash digest into a string and give it back.
* `Verify_Password` Function (verifyPassword): The same method as that of the stored password is employed while hashing the entered password. Match the hash of the entered password with the hash of the stored password.
Output:
GIF: A user continues to enter a significant secret code in the specified box, clicks “Hash Password” to hash the code, and finally confirms to change the status from false to true.
## Enhancing Performance and Features
By regularly updating it, you can improve the performance of your application and introduce upgrades that are meant to match what users look forward to. In this section, we will discuss varying ways of improving the performance and features of our Flutter applications.
### Utilizing new Flutter features
Incorporating these features might enrich the user experience and keep the app competitive when Flutter adds new widgets or capabilities, like the introduction of [SliverAppBar](https://api.flutter.dev/flutter/material/SliverAppBar-class.html) for flexible app bars.
An example of this is `SliverAppBar,` which helps to create application bars that grow and shrink smoothly as the user scrolls, giving them a more fascinating experience. Employing this widget helps to make applications have a more modern and stylish design, offer an improved navigation system, and maximize screen space utilization.
What does it mean by "integrating fresh capabilities such as `SliverAppBar` makes customers understand that the app is recent and maintained? Additionally, the feature shows the developer’s dedication to making the user experience better while at the same time being able to compete with others in the field.
### Optimizing app performance
For Flutter to remain a carefully planned user expertise one should be in the operation of the app frequently checking and making it better accordingly whereby he can use [PerformanceOverlay](https://docs.flutter.dev/perf/ui-performance) or [Dart DevTools](https://dart.dev/tools/dart-devtools) among other tools that provide information about frame rate and GPU render time. Developers can use the live feedback feature in `PerformanceOverlay` where the metrics are displayed on top of the application, enabling them to spot any screen lagging within seconds.
Dart DevTools include many useful performance analysis tools that help developers analyze and optimize the performance of their applications in detail. An example of this is to avoid unnecessary rebuilds by using the const constructor for widgets that do not change hence making the app faster. It is important for developers to continually observe their applications for performance bottlenecks especially when they become more sophisticated, so they can still be fast and reliable.
## Bug fixes and stability
Bug fixes are important for ensuring that your app made using Flutter remains stable and reliable since they prevent glitches, crashes, and user dissatisfaction. The process of constantly improving often enables you to fix any errors, improving how the end users feel while also increasing both the performance and reducing the chances of app rejection that might result in poor reviews sometimes. Several app aspects can be affected by bugs like app functionality and user interface, thus allowing developers to show dedication to quality and customer satisfaction by ensuring timely repairs.
Identifying bugs efficiently by monitoring and testing them continuously and then prioritizing the fixes based on severity and user impact is crucial. When team members collaborate and take advantage of user feedback, it is easier to resolve bugs. A proactive approach to fixing bugs guarantees an app with no disruptions, which earns trust from clients and leads to loyalty.
### Identifying and fixing common bugs
It is very important to constantly monitor crash reports and user feedback so that any common issues can be identified and solved in your Flutter app. Developers who monitor crashes and user complaints can find out how often certain problems, like memory leakages, which cause apps to crash after running for long periods repeatedly, occur. These problems can then be corrected.
Showing developers' resolutions of these issues helps reassure users that the app will function properly all the time. Dealing with them will also keep bad reviews at bay while minimizing user dissatisfaction. Additionally, developers need to implement solutions based on crash reports and feedback so that the app works well on different devices and conditions. This way, the app will succeed in the long run since it never disappoints its customers.
### Stability Improvements
When updating your app, it would be best to put more emphasis on making it stable than anything else. This can be done by taking care of any user interface-related hickeys and other signs one may encounter while using this product. Take, for instance, making changes in how pictures load so that they do not eat into computer space; this could make all the difference regarding its overall robustness. Their purpose is to give individuals who use them a seamless experience without causing any harm to them through accidents because they are always running smoothly. This proves his reputation as a trustworthy application developer who strives hard not to let down their potential customers by giving false hopes when their dreams are about to come true.
To maintain a polished look, address such common issues as UI glitches; to avert user frustration and abandonment, prevent app freezes. Updating the software regularly is an active way of showing that you are maintaining and improving it, thus increasing its longevity and user satisfaction. Flutter applications require life extensions for sustained app stickiness and competitiveness by keeping them up-to-date such that they operate normally on all devices regardless of their conventional patterns for such performance.
<CTA_Middle_Security />
### Regression Testing
It is important to do regression testing before each update to ensure the forward or backward compatibility is okay. This means ensuring that the new changes or updates have not negatively affected any functionality already in place. With the [flutter_test package](https://api.flutter.dev/flutter/flutter_test/flutter_test-library.html) by Flutter, there is [flutter_driver](https://api.flutter.dev/flutter/flutter_driver/flutter_driver-library.html) also to enable automatic testing as well as UI testing which helps make things easier. The process of testing can be streamlined by using these tools. The automatic testing in `flutter_test` is whereby testers can write different test cases checking if every individual function or widget would perform correctly by emphasizing the individual. With these tools, developers can detect early on potential problems, hence diminishing any chances of introducing errors on each update, thus maintaining the app’s consistency and trustworthiness for a good user experience.
### Ensuring Compatibility with Android and iOS Updates
It’s so important to ensure that all versions of new operating system releases work correctly once you release them to maintain their performance levels while keeping the user happy. One must adapt to the changes in OS-specific aspects such as [Android 13’s ](https://www.android.com/android-13/)enhanced permission scheme and make necessary changes to your app to maintain its functionalities. For Flutter, ensuring constant updates on time about platforms ensures everything remains efficient and functions well. To maintain compatibility and optimal performance, one must keep up with platform-specific updates in Flutter. This means one may have to update dependencies, change the code to fit new APIs, and test the app thoroughly on the updated platform. Guidelines as well as tools to aid in maintaining the app’s compatibility are available through resources such as the [Android Developer Console](https://developer.android.com/distribute/console) or [Apple Developer Portal](https://developer.apple.com/).
### Updating Dependencies
Updating dependencies on Flutter regularly allows you to be compatible with the most recent [SDK](https://docs.flutter.dev/release/archive) from Flutter as well as other external libraries (3rd party libraries). This strategy lets you exploit the latest packages’ features, performance boosts, and security improvements. For example, keeping the [Firebase](https://pub.dev/packages/firebase_core) packages up to date introduces new ways of doing things to programmers and protects user data better, enhancing applications' overall performance and dependability.
When you keep up with dependencies, you avoid compatibility troubles due to changes in the Flutter framework or other packages. The Flutter framework is always changing, so one needs continuous updating to avoid having problems with older codes that have become redundant and have discontinuing modifications being done. This way, an author can show that they care about their product and meet the standards set by their peers without making decisions based on personal preference alone. The app appears well-supported when such measures are taken in its development process, portraying the creators' desire to maintain a high-quality product with features conform to market requirements.
Tools such as [flutter_pub_outdated](https://dart.dev/tools/pub/cmd/pub-outdated) can be used to identify outdated packages and, later on, upgrade them with the help of ‘flutter pub upgrade’. There should be automated testing to guard against issues that come as a result of the updates while at the same time ensuring that no regression is introduced and that there are any unexpected behaviors. By keeping up with all these processes, the company maintains its competitiveness against others within its realm of operation while still keeping its app up-to-date and stable.
### Handling deprecated APIs
It is important to replace deprecated APIs with recommended ones within Flutter so as not only to keep compatibility but also to have a future-proof app. For example, using the [http](https://pub.dev/packages/http) package for networking tasks instead of the outdated [HttpClient](https://learn.microsoft.com/en-us/dotnet/api/system.net.http.httpclient?view=net-8.0) is necessary. With the evolution of Flutter, there is a likelihood that some problematic APIs will be dropped, thus leading to instability in an application.
Using modern replacements like the' HTTP' package benefits developers with better performance, error handling, and a simplified API. Switching smoothly with the help of Flutter’s official documentation and migration guides would mean developers have stable applications that benefit from the newest functions and enhancements. Such a move increases both stability and efficiency, leading to progressive reliability.
## Stay informed about SDK releases
To keep app stability and compatibility up-to-date, keeping track of Flutter SDK releases and their implications is important. From time to time Flutter introduces new features, performance enhancements, and sometimes even breaking changes. This will inform developers about what new things they may be able to use as well as how well performance can be optimized quickly with some bug fixes that appear, among other things. When developers read release notes and documentation, they can understand changes, APIs that are not supported anymore, and recommended migrations. This will help them to strategize for their upgrade and sync development roadmaps. As a result, developers are expected to follow up on Flutter's official channels and participate in its community activities to remain relevant and gain experience from others in the field.
### Monitoring Flutter Release Notes
It is very important for app security if often people check Flutter release notes for security patches and updates. Security tokens help in addressing vulnerabilities like [XSS ](https://en.wikipedia.org/wiki/Cross-site_scripting)vulnerabilities in plugins, for example [webview_flutter](https://pub.dev/packages/webview_flutter), among many other things. When developers are more informed, they can be able to set up resources for testing new features better than before, which is good because then they can know what they should do first, especially when it comes time to test these fresh capabilities. That also helps us show our commitment to data safety concerning the customers’ information, and the clients themselves do trust us. To get detailed information about security patches and recommended actions, subscribe to official Flutter channels like the [blog](https://docs.flutter.dev/release/whats-new) or [GitHub](https://github.com/) repository. This active strategy will help to ensure safety and protect apps from potential threats.
### Understanding security patches
Regarding the safety loopholes that Flutter and its plugins are facing to protect user data, maintaining the safety of any app requires that one is frequently updated on it. Thus, if we were to consider an instance whereby the [shared_preferences](https://pub.dev/packages/shared_preferences) plugin had undergone a flaw that made it possible for confidential information to be leaked, then there was no alternative but for programmers using this service to be forced to quickly switch to fixed versions. In addition, any potential risk may be managed through regular monitoring of insecurities notifications as well as being a member of such things as Flutter’s forums, among others, which will make it easier so long those who participate avoid any kind or form of threats. By incorporating some security protocols like encrypting data and secure authentication, we boost security levels in our app development, debugging, or deployment of Flutters, which should ensure that security flaws are exposed early and tackled in time for seamless operations and secure data privacy.
### Automated Testing
It’s very important to do automated testing using the [flutter_test](https://api.flutter.dev/flutter/flutter_test/flutter_test-library.html) mechanisms within Flutter to validate the app’s behavior and secure it. For instance, if we take unit tests, they test whether user data is cleaned up well before any [SQL](https://www.mysql.com/) code execution that could lead to an injection attack on servers when proper security measures are in place.
Depending on constraints set, including these factors in the controls available can be input validation, authentication methods, or data encryption. The vast areas of input validation, authentication mechanisms, and data encryption form the basis of the automated tests. Integration tests, on the other hand, are simulated user experiences that check the authentication process and protect the data. Furthermore, the functionality of the security-related UI element is also tested by widget and UI tests. As these tests are included in the automated suite, developers can adequately uphold app security and integrity.
### Manual testing for edge cases
It is important to not overlook the conducting of hand-testing in Flutter when it comes to pinpointing security flaws that automated tests can ignore. This is where we go through apps one by one just to make sure they are functioning right while also addressing their security aspects, like preventing any kind of injection attack by trying to put a number within a username field.
Another part about the manual test is that it has some special purposes too; discovering other interesting usage cases that were missed in automatic testing so far and showing some weaknesses plus strange ways of processing data in the software. It also evaluates how simple it is to do different tasks with it, its accessibility, and overall user experience by running over usability problems and layout errors.
Additionally, it assesses the user interface, accessibility, and overall user experience of the application by identifying usability issues and layout errors. It also evaluates how easy it is to achieve various functionalities using the system, along with how accessible it is and the general user experience by examining usability challenges as well as design mistakes. In security-centered manual testing, it is important to verify that the data encryption and secure network transmission have been done correctly.
During security-focused manual tests, verifying the correct execution of data encryption as well as secure networking becomes very crucial. It helps to investigate compatibility and achieve uniformity by trying various gadgets and platforms. To establish compatibility and consistency, we can check if it works well on different devices through the usage of assorted gadgets and platforms.
### Security-focused Testing
Conducting security tests that are focused on critical findings of vulnerabilities in Flutter applications. Rooting out of insecure data storage patterns by security audits while penetration tests interfere with actual life assaulters, revealing weaknesses such as [SQL injection](https://en.wikipedia.org/wiki/SQL_injection) or XSS. Regarding coding language alteration, security flaws can be detected within the changes made to the software, for example, through input validation and encryption.
Making use of security testing tools and libraries, such as [owasp](https://en.wikipedia.org/wiki/SQL_injection) and [dart-secure](https://pub.dev/packages/flutter_secure_storage), improves the effectiveness of security testing. To maintain app security, it is very important to keep these in consideration when the Flutter team and security experts give them disseminate the information. If there is regular security-focused testing, it helps to ensure that varieties of matters that might pose security threats to Flutter apps are well handled and this handles.
### Secure data handling
It is important that data records in apps made by Flutter are correctly managed and tightly secured to prevent multiple data breaches and unauthorized entries. The process involves setting up protective data storage measures that guard against confidential data exposure, such as user account details, to encryption technologies. Make sure that when data is transmitted across networks, it is secure by today's standards: use HTTPS protocols together with [SSL/TLS](https://www.digicert.com/what-is-ssl-tls-and-https) encryption techniques for this matter. Moreover, strong authentication mechanisms such as [OAuth 2.0](https://oauth.net/2/) and [Firebase Authentication](https://firebase.google.com/docs/auth) have to be implemented for any harmful feature and information protection purposes. Such access limitations can be achieved by combining these two advanced authentication forms alongside Role-Based Access Control, among others. Mitigating unnecessary data handling decreases the chances of experiencing data breaches by limiting the amount of what all users provide through reduction techniques, including, among others, minimalism principles and pseudonym creation, which is achieved through this means.
## Automated Testing
The quality of your Flutter app depends on automated tests, which are important in detecting problems early in the development process. This section will discuss various techniques for carrying out automatic tests on our Flutter apps.
### Unit Tests, Integration Tests, and UI Tests
[Flutter_test](https://api.flutter.dev/flutter/flutter_test/flutter_test-library.html) and [flutter_driver](https://api.flutter.dev/flutter/flutter_driver/flutter_driver-library.html) are aides that automate examinations which enable rapid test implementation and seamless integration into CI/CD workflows to achieve uninterrupted tests as well as rapid application deployment. A synergy of these verification techniques is an assurance that those mobile applications made using Flutter output are of excellent quality and that consumer satisfaction is achieved.
By adding the above-mentioned tests, developers can get all-inclusive test coverage across different strata of the application. These tests help in detecting defects and regressions earlier within the development process, hence enhancing best coding practices and the application's dependability.
### Test Coverage Analysis
It is important to monitor test coverage in Flutter to ensure that all critical elements of the application are adequately tested. Generating test coverage reports and finding areas for further testing can be done using tools such as pcov. If you look at these reports, you will understand those sections with less coverage than others, which will help you concentrate on them during your testing process. Consequently, it guarantees that the most significant features and crucial parts of the code are well-examined, avoiding hidden errors or bugs.
## Routine Monitoring
Identifying performance problems and other issues, like security vulnerabilities, is critical for Flutter applications to function effectively. Without monitoring, we would not know what is going wrong with the app until it has gone so far that we cannot fix it anymore. This explanatory section explains why we need to keep our eyes open through regular checks.
### Monitoring App Performance
Developers can track app performance metrics like response time and CPU usage using performance monitoring tools such as [Firebase Performance Monitoring](https://firebase.google.com/docs/perf-mon) by Google. This allows them to keep an eye on the performance of their applications at all times when they have integrated these tools and, therefore, discern what is holding them back in terms of performance to improve upon this.
### Crash Reporting
Integrate tools similar to [Firebase Crashlytics](https://firebase.google.com/docs/crashlytics) for improved diagnosis of application failures by collecting logs from such crashes. The moment applications crash, these tools send immediate notifications about this. This enables the app makers to handle these app failures urgently. Consequently, they can boost their app performance by eliminating these crashes, hence enhancing their clients’ user experience altogether. Automating some of these processes, such as gathering data concerning crashes, will automatically make it much easier for you to know what occurred.
### Logging and Analytics
Use logging tools and analytics tools such as [Firebase analytics](https://firebase.google.com/docs/analytics) for monitoring user activities and app usage trends. Firebase analytics provides data on how users interact with applications and where they are used most. This allows developers to know the behavior and preferences of users so they can make changes in their apps with the help of data. Logging refers to events and activities that users undertake while using an application. The analytics tools analyze the collected data to produce reports and visualize app usage trends, making it possible to make decisions based on facts. Monitoring analytics data regularly enables software engineers to detect parts of the app that must be optimized and prioritize developing features. By following the end user actions, software engineers can improve customer satisfaction through increased app engagement.
## Rollback Plan for Failures
It is crucial to have a plan to roll back if the application fails so you can return to an earlier working version immediately. This plan indicates how one can reverse any alterations made to the system and bring back the app to its proper operation mode. Moreover, it contains ways of recognizing such situations that demand going back and those who should be in charge since it will serve as a guideline during execution. Automated rollback protocols simplify this operation, reducing the time wasted trying to solve the problem. Keeping in touch with the people concerned will help guarantee that everybody understands what needs to happen in the system failure recovery process.
### Rollback Procedures
It is vital to have rollback procedures that can allow going back to an unstable version of an application swiftly when such instances occur. Having defined what entails a rollback, software engineers get direction on how to recover from such instances and reduce time when the system is not fully operational. Automating this process using scripts ensures timely response to major system errors, reducing cases where manual intervention may lead to increased numbers of errors creeping in unintendedly. These procedures guide as regards at what point is rolling back necessary or who should do it.
### Communication strategies for users
To keep Flutter apps transparent and reliable, effective communication with users on rollbacks and potential impacts is important. Notifications on the app and social media platforms draw users' attention to problems and their resolution steps, thus making sure that they are cognizant of what is going on concerning each case. Instead of waiting until they happen again, notifying them beforehand helps minimize their annoyance or irritation whenever rollbacks occur.
## Regular data backups
Backing up data regularly is critical for preventing data loss and ensuring business continuity in Flutter applications. They are like a safety net that allows saving time when emergencies happen by getting back data instantly instead of waiting for long hours or days during which work could be interrupted temporarily, thus causing delays. The significance of backing up is reiterated in the following ways: through holding useful information, like user-generated content as well as database data, which are not supposed to disappear completely; however, the updates have to be quick. For it to happen time after time, one must decide that he/she will not give up on data secrecy, thus managing to show his/her clients that they can rely on him/her at any time without worrying about losing their information since all these measures help safeguard against loss of information along with maintenance of secure networks.
### Cloud-based Backup Solutions
Protecting data is critical to ensure that the data is protected and available. With cloud storage options like [Firebase Cloud Firestore](https://firebase.google.com/docs/firestore) and [Google Cloud Storage](https://cloud.google.com/storage), app data backups are automated. This course of action ensures the safety of all information, which can be retrieved whenever required. For example, Firebase Storage allows automatic backup of user-generated content, including images or documents, at a go. This way, reliable, scalable app data storage solutions are provided. For complete archiving, data must be saved in the cloud at all times. Therefore, there is less likelihood of the overall loss of valuable information because records will always be available over the internet cloud. A backup routine should be run regularly so that it does not become overwhelming.
### Local Data Backup
Create local backup systems to store app data on the phone or another source for better safety and access. It’s possible to go ahead and make your local [SQLite](https://www.sqlite.org/) database backup, too, by just taking advantage of Flutter’s [path_provider](https://pub.dev/packages/path_provider) package. It has been designed in such a way that one can use it to create device storage locations as well. The purpose of this package is to help developers back up SQLite databases since it provides this option in these places. Local backups guarantee that app information will always be reachable even when there is no online connection or external assistance.
### Scheduled backup jobs
Accomplish automatic backup work by continuously planning them with the use of Flutter’s [flutter_local_notification](https://pub.dev/packages/flutter_local_notifications) package, which makes it possible for one to have daily copies saved for different categories of details displayed on an application needed also informing users concerning the same hence transparency is a must. Because these copies are scheduled for specific times, they will not require any human interruption, which means that their dependability is ensured throughout. There is no need then again. Schedule copies are done automatically with no manual input needed; hence, stability and reliability are always assured. Backup tends to also make sure it mitigates against all types of unexpected losses. Moreover, one will receive messages that assist in giving comfort regarding the security level of his lance; the same clarifies things that are happening in progress.
## Disaster Recovery Planning
For Flutter apps to be able to recover from devastating incidents, they must have a disaster recovery plan. This plan considers ways to lessen risk, handle emergencies, and resume service provision. It also has options for saving data, creating copies, and other special devices for automatic transfer if the current fails. The effectiveness of the plan is regularly checked through testing. This involves putting in place communication strategies that would help in getting in touch with concerned parties when there is an emergency. The key idea in the plan is assessing how bad it is and then deciding what needs to come first when recovering after such incidents.
### Backup Restoration
Data protection in a Flutter can be achieved by implementing methods of data recovery in instances of data loss or corruption. An example is scripting for the restoration of Firebase Firestore backups when accidentally deleted. It enables rapid recovery from incidents where information was lost and minimizes interruptions in service provision by the program. With such measures in place, Flutter applications remain dependable by securing essential data.
### Failover Systems
Ensuring uninterrupted service when servers are down is important in Flutter. What this means is that, to automatically change to another server in case one fails, such failover systems as load balancers or redundant server configurations must therefore be set up. This will make sure that should anything happen to servers, then all users can still access the app because failover systems have been put in place by the developers. They enhance the reliability of this software application while reducing its unavailability periods.
## Data Replication
Of course, since we do not want to lose any data we replicate it in several data centers or geographic regions like this: The same information can be copied to various locations around the globe using a multi-region replication service provided by Firebase Realtime Database.
### Version Control
It is important to use version control systems such as [git](https://git-scm.com/) to facilitate the management of amendments in the code foundation of the app. We utilize this method by monitoring for modifications, collaborating well, and maintaining various editions of our application. Tagging stable releases through git enhances identifiable versions that can be rolled back whenever faults come up. Henceforward, there shall be a uniform track in which the changes can be identified for those developers who have felt like moving backward in an earlier [HTML](https://html.com/) era.
### Rollback Procedures
There is a need in Flutter for having a backup plan as far as rolling back things is concerned as they may sometimes just not work out due to one thing or another or even because nobody knows how well they might turn out eventually when left alone entirely so they must involve the development of programs that deploy earlier versions of programs should something go wrong at any point during their execution which should then make it possible go back whenever things get too messy thus preventing further problems from occurring just like what usually happens when we encounter an error message saying that some kind bugs cannot be found at all or something similar but not really. In other words employing rollback plans, developers can have a clear idea about how they can always get back to safe grounds, which encompass writing certain algorithms that will make sure our software does not stop on its tracks every time you are near crashing or certain conditions are achieved Therefore in doing this you come up with code so that the systems installed respond quickly when there occurs a catastrophe lowering loss of income.
### Communication strategies for users
It is extremely important to inform users in Flutter about rollbacks and potential repercussions on their experience in advance. This requires pushing out notifications through different channels, including an application itself and social networks, showing subscribers what has happened and how it has been resolved. For that reason, the developers can continuously update customers about any interruptions or modifications to their operations. This helps developers retain openness whilst nurturing reliance among consumers, leading them to appreciate the conditions in which people live and act.
## Conclusion
In this guide, we have looked at the necessary aspects of upgrading and shielding Flutter applications which are critical for their function, performance as well and integrity. Complying with good practices while at the same time incorporating strong security measures helps developers to produce Flutter apps that are dependable and safe from unauthorized access where client information is concerned and ensures trustworthiness between end users.

1,921,245 | Structured Content guide: Reusable blocks for scalable websites | Is your site too inconsistent? Is your content team ineffective? Are you spending too much time on... | 0 | 2024-07-12T14:01:24 | https://dev.to/momciloo/structured-content-guide-reusable-blocks-for-scalable-websites-4jon | Is your site too inconsistent? Is your content team ineffective? Are you spending too much time on technical SEO? Structured content is the solution. This guide explores the basics of structured content and how it can help solve common challenges in content management. Learn how to create reusable content blocks and build scalable, efficient websites. Discover the differences between structured and unstructured content and how using a headless CMS can streamline your content strategy.
## What is structured content?
Structured content is organized, reusable, and machine-readable data. It’s typically stored in a database, making it easily searchable and adaptable across various platforms. Structured content follows a predefined schema, which ensures consistency and efficiency in content management.
### Key characteristics of structured content
There are three key touchpoints when it comes to content structure**:**
- **Organized**: Arranged in a predictable, systematic way.
- **Reusable**: Can be easily repurposed across different channels.
- **Machine-readable**: Easily interpreted by software, facilitating automation and integration.
## Structured vs. Unstructured Content
This is actually a comparison between organized and unorganized content Structured content - sometimes called component content - is content that is organized predictably. To manage that, structured content follows a set of rules - called a schema, information architecture, [content modeling](https://thebcms.com/blog/content-modeling-basics) (more on this below) or simply put organization.
On the other side, content without structure-unorganized content is normally intended for single-use, which is difficult to adapt and evolve. The focus here is on the context of how information is consumed. In contrast, structured content is intended to function across different frontends, with the highest priority on the relationships between content pieces, not the context.
These different focuses have a great influence on building website structure and also on content manipulation.
For example, consider a company that frequently posts job listings on its website. In an unstructured content approach, each job listing might include repetitive information such as a company description, address, and application instructions.
With structured content, this repeatable information would be stored in separate modules. Each job listing would then simply link to these modules, ensuring consistency. Whenever there is a need to update the company description, the changes would be made in one place and automatically reflected across all job listings.
For a better understanding of how this content manipulation works check out: [BCMS Widgets - Reusable structured content - everything you need to know](https://thebcms.com/blog/bcms-widgets-reusable-structured-content-tutorial)
And to understand why structure is important in content delivery here’s an in-depth comparison table:
## Components of structured content
A structured content creation system consists of various components and systems. Adding more layers of information improves the content structure, making it easier for users to develop content and for consumers to consume it.
The following components make content well-organized, easily manageable, and highly adaptable.
### Content types
[Content types](https://thebcms.com/blog/content-modeling-headless-cms) define the different kinds of content that will be created and managed. Examples include articles, product descriptions, user profiles, and event listings. Each content type has its own set of attributes and rules.
### Fields and Attributes
Fields and attributes are the specific elements that make up a content type. For instance, a blog post content type might include fields such as title, author, publish date, body text, and tags. These fields ensure that each piece of content is complete and follows a consistent format.
### Metadata
Metadata provides additional information about the content, such as keywords, categories, and descriptions. This helps with organizing, searching, and optimizing content for SEO purposes. Metadata makes content more discoverable and manageable to search engines.
### Content models
Content models define the structure and relationship between different content types and their fields. They ensure that content is organized systematically and can be easily reused and repurposed across various platforms.
### Schemas
Schemas are sets of rules that define the structure and organization of content. They ensure that all content follows a consistent format and can be easily interpreted by machines. Schemas are essential for creating machine-readable content that can be easily indexed and searched.
### Modules and components
Modules and components are reusable pieces of content that can be combined to create larger pieces of content. For example, a product description module might be used across multiple product pages.
### APIs and Integration
APIs enable structured content to be accessed and integrated into various systems and platforms. This allows seamless content delivery across websites, mobile apps, and other digital channels. APIs ensure that content can be easily shared and reused.
### Version control
Version control tracks changes to content over time, allowing for the management of different versions and the ability to revert to previous versions if needed. This is crucial for maintaining accuracy and consistency across all content.
## How to create structured content
Creating structured content involves a systematic approach to ensure your content is organized, reusable, and easily manageable. Here’s how you can create valid structured content step-by-step:
### Step 1: Identify content types
List the different kinds of content your business needs to manage, such as articles, product descriptions, user profiles, event listings, and FAQs.
For example, content types for job listings, include fields like:
- Job title
- Image
- Location
- Job description
- Requirements
### Step 2: Define content models
Outline the structure, fields, attributes, and relationships between different content pieces for each type.
### Step 3: Create schemas
**Develop schemas for each content type**: Use XML to create schemas that define the structure and organization of your content. These schemas provide a set of rules that ensure your content follows a consistent format.
```jsx
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="jobListing">
<xs:complexType>
<xs:sequence>
<xs:element name="title" type="xs:string" />
<xs:element name="image" type="xs:string" />
<xs:element name="location" type="xs:string" />
<xs:element name="description" type="xs:string" />
<xs:element name="requirements" type="xs:string" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
```
### Step 4: Incorporate metadata
Add metadata for organization and SEO: Include metadata elements like keywords, categories, descriptions, and tags to enhance searchability and optimize content for SEO. Example: Add metadata like tags for job category, employment type, and keywords to improve searchability and SEO.
### Step 5: Use XML Tags
Tagging content with XML: Use XML tags to label and structure your content. Tags are enclosed in ‘<’ and ‘>’ characters and indicate a component's start and end. Tags are nested to show relationships between content pieces, providing clear structure and meaning to your content.
```jsx
<jobListing>
<title>Software Engineer</title>
<image>http://example.com/images/software-engineer.jpg</image>
<location>San Francisco, CA</location>

<metadata>
<category>Engineering</category>
<employmentType>Full-time</employmentType>
<keywords>Software Engineer, JavaScript, React</keywords>
</metadata>
</jobListing>
```
### Step 6: Leverage APIs for Integration
Integrate content with various platforms: Use APIs for content delivery across websites, mobile apps, and other digital channels. Ensure your content management supports API-driven content management.
Example: [How to use Headless CMS as your job board CMS](https://thebcms.com/blog/headless-cms-as-job-board-cms)
Using these steps, you will be able to create well-organized, manageable, and highly adaptable structured content that will reach and engage your target audience.
At the end of this structured content example, I leave you with a content structure template, which you can use as a guide for creating a structure.

## Kinds of relationships in structured content (with examples)
Content relationships define how different pieces of content relate to each other within a system. These relationships are crucial for organizing content in a way that makes it reusable, scalable, and easily manageable. Here are the main types of relationships, along with examples of each:
### Hierarchical relationships
The hierarchical relationship organizes content into a parent-child structure. This is useful for creating nested structures such as categories and subcategories.
Example: An online store has a main category "Electronics" with subcategories "TV", "Mobile Phones" and "Laptops".
### Associative relationships
Links content pieces that are related but do not fit into a hierarchical structure. Often used for tagging and metadata systems.
Example:
Tags and keywords: An article about smartphones is tagged with keywords like "technology", "gadgets", and "reviews".
### Referential relationships
Uses references to connect content pieces, allowing for content reuse without duplication.
Example:
Author profiles: Multiple articles reference the same author profile, ensuring consistency across all publications. Like this:

- [Content Hub vs Content Federation: Is the same thing?](https://thebcms.com/blog/content-hub-vs-content-federation)
### Sequential relationships
Organize content in a specific order, which is essential for content that needs to be consumed in a particular sequence.
Use case:
[HubSpot SEO Online Course](https://academy.hubspot.com/courses/seo-training)
A course on SEO that has modules that must be completed in sequence.
### Compound relationships
Groups multiple content pieces together as a single entity. This approach is commonly used in e-commerce for product bundles.
So, on [Shopify’s example](https://help.shopify.com/en/manual/products/bundles), you can see how to master this kind of relationship.
### Bidirectional relationships
Bidirectional relationships in structured content are used to create mutual references between content pieces, ensuring that each item links back to the other. This is particularly useful for enhancing user navigation and engagement on a website.

1,921,247 | Docker Compose Develop Watch and Syncing Files from the Host Container to a Service | This thread has helped me better understand the "develop" behavior with Docker Compose The Docker... | 0 | 2024-07-12T14:02:19 | https://dev.to/rudolfolah/docker-compose-develop-watch-and-syncing-files-from-the-host-container-to-a-service-18hh | docker, containers, development, productivity | [This thread has helped me better understand the "develop" behavior with Docker Compose](https://github.com/docker/compose/issues/11102)
[The Docker Compose documentation of "Example 1" in "Use Compose Watch"](https://docs.docker.com/compose/file-watch/#example-1) does a pretty good job explaining things. Perhaps part of it should be added to [the Compose File - Develop page](https://docs.docker.com/compose/compose-file/develop/) instead of hidden by links?
>After the service is up, the watch mode starts monitoring the target directories and files. Then, whenever a source file in the web/ directory is changed, Compose syncs the file to the corresponding location under /src/web inside the container. For example, ./web/App.jsx is copied to /src/web/App.jsx.
>
>Once copied, the bundler updates the running application without a restart.
>
>Unlike source code files, adding a new dependency can’t be done on-the-fly, so whenever package.json is changed, Compose rebuilds the image and recreates the web service container.
This appears to be the ideal process:
1. build the image with the current state of files copied into it
run compose with watch
2. whenever a file changes, rebuild the image so it has the updated state of files within it
Alternatively, outside of Docker Compose for syncing files (and based on the suggestions in the thread):
1. build the image with the current state of files copied into it (use a "watch" or "reload" command built into whatever app you're running)
2. run compose (do not use develop or watch)
3. run `docker compose cp ./src app:/src`
this should trigger the watch/reload command within the container
Another option is to build a base image that *does not* include source code and *only* builds an environment in which the source code can be built or run. Then, a volume can be mounted into the container with the latest source code from the host environment, and the code can be run.
Something like this:
1. build the image with the environment
2. run compose with a volume mounted
3. run the steps in the container to build/run the source
It all depends on your developer workflow and what is understandable and can be used daily with minimal disruption to [the developer feedback loop](https://medium.com/hootsuite-engineering/optimizing-the-feedback-loop-a-key-to-great-developer-productivity-f567c4e80c80).
Things to consider:
- how often are dependencies changing? should they be re-installed within the container or should the image be rebuilt (since one of the steps is installing dependencies)?
- is there a "watch" or "reload" command that reloads your app based on files changes?
- how much time does it take to rebuild the image? is it acceptable to yourself and to your team to wait for a rebuild on every set of source code changes? does it slow the developer feedback loop too much? | rudolfolah |

established a reputation for prioritizing security and trustworthiness in the
volatile world of cryptocurrency trading.
### Lessons Learned from Past Security Breaches
The history of cryptocurrency exchanges is fraught with numerous security
breaches, each providing valuable lessons for the industry. One of the most
infamous incidents was the Mt. Gox hack in 2014, where approximately 850,000
bitcoins were stolen, leading to the exchange's eventual bankruptcy.
## Future Trends in Crypto Exchange Security
As the cryptocurrency market continues to evolve, so too do the strategies for
securing exchanges. Future trends in crypto exchange security are likely to
focus on the integration of more advanced technologies like artificial
intelligence (AI) and machine learning (ML) to detect and prevent suspicious

This fat-soluble vitamin is essential for bone health, immune function, and overall well-being. In this article, we will delve into the origins, historical uses, societal benefits, and recommended practices for incorporating vitamin D into your daily routine. Additionally, we will highlight complementary herbs, cautionary measures, and provide necessary disclaimers.</p>
<h2>What is <a href="https://www.webmd.com/vitamins/ai/ingredientmono-929/vitamin-d">Vitamin D</a>?</h2>
<p>Vitamin D is a fat-soluble vitamin that helps your body absorb calcium, promoting bone growth and health. It also supports immune, brain, and nervous system health, regulates insulin levels, and supports cardiovascular function. There are two main types of vitamin D: D2 (ergocalciferol) and D3 (cholecalciferol). While both are beneficial, vitamin D3 is more effective at raising blood levels of vitamin D.</p>
<h2>Origins and History of Vitamin D</h2>
<p>Vitamin D is unique because it can be synthesized in the skin upon exposure to sunlight. The discovery of vitamin D dates back to the early 20th century when researchers identified its role in preventing rickets, a bone-weakening disease. Historically, societies living in northern latitudes or regions with limited sunlight exposure have been particularly susceptible to vitamin D deficiency.</p>
<h2>Traditional Methods of Use</h2>
<p>Traditionally, vitamin D was obtained through sun exposure and diet. Fatty fish, liver, egg yolks, and fortified foods such as milk and cereal have been dietary sources of vitamin D. Ancient societies, including those in Scandinavia, consumed large amounts of fish liver oil to prevent deficiencies during long, sunless winters.</p>
<h2>Societal Use and Benefits</h2>
<p>Many societies have recognized the importance of vitamin D. For instance, the ancient Egyptians revered the sun and its health benefits, likely obtaining vitamin D through ample sun exposure. In the 19th century, cod liver oil became a common supplement in Europe and North America to combat rickets and other bone-related ailments.</p>
<h2>Complementary Herbs and Supplements</h2>
<p><a href="https://www.gearisle.com/okay-gummies-calcium-vitamin-d-60-cnt-cotton-candy-flavor-joint-health">When taking vitamin D, it can be beneficial to pair it with certain herbs and supplements</a> to enhance absorption and effectiveness:</p>
<ul>
<li><strong>Calcium</strong>: Vitamin D aids in calcium absorption, promoting bone health. Taking them together ensures optimal benefits.</li>
<li><strong>Magnesium</strong>: This mineral helps convert vitamin D into its active form in the body.</li>
<li><strong>Vitamin K2</strong>: Works synergistically with vitamin D to ensure calcium is directed to bones and teeth, not arteries.</li>
</ul>
<h2>Cautions and Considerations</h2>
<p>While vitamin D is essential, there are precautions to consider:</p>
<ul>
<li><strong>Over-supplementation</strong>: Excessive vitamin D intake can lead to toxicity, resulting in hypercalcemia (high calcium levels), which can cause nausea, weakness, and kidney problems.</li>
<li><strong>Medication Interactions</strong>: Vitamin D can interact with medications such as steroids, weight loss drugs, and cholesterol-lowering medications.</li>
<li><strong>Sun Exposure Risks</strong>: While sunlight is a natural source of vitamin D, excessive sun exposure without protection can increase the risk of skin cancer.</li>

1,921,253 | Entendendo Ponteiros | Em graduações da área de tecnologia, existem conceitos e matérias que geralmente assustam os alunos,... | 0 | 2024-07-12T14:08:50 | https://dev.to/adrielh024/entendendo-ponteiros-1n8e | c, cpp, tutorial | Em graduações da área de tecnologia, existem conceitos e matérias que geralmente assustam os alunos, alguns dos principais exemplos são matérias relacionadas a Programação Orientada a Objetos e Cálculo, outro exemplo são algumas noções mais abstratas tal como ponteiros, principalmente em C, tema deste artigo.
Diferentemente de nós, os computadores não conhecem uma determinada informação por um “rótulo” ou “nome”, e sim pelo endereço onde este dado está alocado na memória. Podemos pensar na memória como um conjunto de “células” que contém um número de bits que armazenam 0 ou 1 e que cada célula está associada a um determinado endereço onde armazena alguma informação para que os programas executados pela máquina possam acessar estes dados e os manipular.
Tendo em vista que para um programa poder usar um dado ele precisa saber de seu endereço na memória, podemos conceber o conceito de ponteiro. O ponteiro é uma variável que “aponta” para algum outro dado, é como se fosse um espaço na memória destinado a guardar o endereço de outra variável ou informação para que esta possa ser manipulada.
Mas agora vem a pergunta, qual a utilidade de um ponteiro? O ponteiro permite algumas operações mais complexas envolvendo a memória, tal como alocação dinâmica com Malloc ou a criação de estruturas de dados mais complexas, etc. Além disso, há alguns detalhes que não são tão facilmente percebidas pelos estudantes em um primeiro momento, tal como o fato de o nome de um vetor ser um ponteiro. Isto mesmo, um vetor nada mais é que um “ponteiro fixo” que aponta para uma determinada posição na memória e que nós usamos o índice para manipular de acordo com a necessidade.
Outra utilidade é a manipulação de dados por referência, por exemplo: passar uma matriz como parâmetro para outra função, permitindo que a matriz original seja modificada ao invés do valor ou objeto passado ser apenas uma cópia, algo que por exemplo ocorre no Javascript onde não há conceito de ponteiro (ao menos não explicitamente), por exemplo:
```
#include <stdio.h>
int vet [5] ={10,20,3,4};
void somadez(int * ref){
for(int i=0;i<5;i++)
ref[i]+=10;
}
int main () {
somadez(vet);
for(int i=0;i<5;i++)
printf("%i\n",vet[i]);
return 0;
}
saída:
20
30
13
14
note que quem foi alterado foi o vetor original
```
Outra utilidade não tão evidente de ponteiros, desta vez para linguagens orientadas a objeto, onde podemos, por exemplo, criar objetos dinâmicos e facilitar o trabalho com herança e polimorfismo.
Temos esse exemplo a baixo com C++:
```
#include <iostream>
using namespace std;
class Animal{
public:
virtual void som();
};
class Cachorro : public Animal{
public:
void som(){
cout << "auau";
}
};
int main () {
Animal * ClasseBase;
Cachorro ClasseFilha;
ClasseBase = &ClasseFilha;
ClasseBase->som();
//neste caso podemos usar o ponteiro para acessar métodos e atributos de uma classe derivada.
return 0;
}
```

1,921,256 | Singly Linked List using C++ | In this C++ program, I will show you a basic singly linked list. It begins by defining a node... | 0 | 2024-07-12T14:32:23 | https://dev.to/praneshchow/singly-linked-list-using-c-5008 | cpp, linked, datastructures, algorithms | In this C++ program, I will show you a basic singly linked list. It begins by defining a `node` structure to store an integer (`data`) and a pointer to the next node (`next`).
### Node Structure Definition:
```cpp
struct node {
int data;
node* next;
};
```
data to store the integer value.
next to store the pointer to the next node in the list.
### Head Pointer Initialization:
```cpp
node* head = NULL;
```
### Create First Node:
Creates the first node and assigns its address to the head.
```cpp
node* temp1 = head;
node* temp = new node();
temp -> data = x;
temp -> next = NULL;
head = temp;
```
For each subsequent input, a new node is created and appended to the end of the list. The program uses a helper function, `print`, to display the entire list after each insertion, showcasing the current state of the list with the memory addresses of nodes and their data.
Loop to Add More Nodes:
```cpp
for (int i=0; i<n-1; i++) {
cout << "Data : ";
cin >> x;
node* temp = new node();
temp -> data = x;
temp -> next = NULL;
temp1 = head;
while(temp1->next != NULL) {
temp1 = temp1->next;
}
temp1->next = temp;
print();
}
```
Creates a new node. Finds the end of the current list. Appends the new node to the end. Then Calls the print function to display the list.
## Linked list using C++ (Full code)
```cpp
#include<bits/stdc++.h>
using namespace std;
void print();
struct node{
int data;
node* next;
};
node* head = NULL;
int main(){
int x, n;
cout << "How many data want to input: ";
cin >> n;
cout << "Input your 1st data: ";
cin >> x;
node* temp1 = head;
node* temp = new node();
temp -> data = x;
temp -> next = NULL;
head = temp;
for (int i=0; i<n-1; i++){
cout << "Data : ";
cin >> x;
node* temp = new node();
temp -> data = x;
temp -> next = NULL;
temp1=head;
while(temp1->next!=NULL){
temp1 = temp1->next;
}
temp1->next = temp;
print();
}
}
void print(){
node* temp=head;
cout << "List is :" << endl;
while (temp!=NULL){
cout << "temp: " << temp << " Data: " << temp->data << " next: " << temp->next << endl;
temp = temp-> next;
}
}
```

1,921,260 | Mathematics for Machine Learning - Day 5 | Disclaimer Today's topic will still be split between today and tomorrow. Since you might... | 27,993 | 2024-07-12T14:27:26 | https://pourterra.com/blogs/5 | learning, machinelearning, tutorial, beginners | 
## Disclaimer
Today's topic will still be split between today and tomorrow. Since you might tell from the meme, I don't know if I'm a genius, an idiot, or that's just how math maths. Usually it's the second one.
Today we'll discuss
1. Elementary Transformations
2. An example of using _row-echelon form (REF)_ to help us find the particular and general solutions
3. A missing connection between previous discussion.
Tomorrow, I'll write about what's _row-echelon form (REF)_ even is and what's the difference between using gaussian elimination to create a upper triangle matrix. Honestly, I'm just curious because that's what REF seems to me...
## Elementary Transformation
Basically, it transforms the matrix into a simpler form without changing the result. We can transform it in a few different ways
1. Exchange of two equations (rows in the matrix representing the system of equations)
2. Multiplication or divisions of an equation (row) with a constant.
3. Addition or subtractions of two equations (rows)
### Example
#### System of equations
{% katex %}
\begin{align*}
-2x_1 + 4x_2 - 2x_3 - 1x_4 + 4x_5 &= -3 \\\
4x_1 - 8x_2 + 3x_3 - 3x_4 + 1x_5 &= 2 \\\
1x_1 - 2x_2 + 1x_3 - 1x_4 + 1x_5 &= 0 \\\
1x_1 - 2x_2 + 0x_3 - 3x_4 + 4x_5 &= a
\end{align*}
{% endkatex %}
#### Matrix-vector multiplication form
Let's divide the variables and the constants!
{% katex %}
\begin{pmatrix}
-2 & 4 & -2 & -1 & 4 \\\
4 & -8 & 3 & -3 & 1 \\\
1 & -2 & 1 & -1 & 1 \\\
1 & -2 & 0 & -3 & 4
\end{pmatrix}
\begin{pmatrix}
x_1 \\\
x_2 \\\
x_3 \\\
x_4 \\\
x_5
\end{pmatrix}
=
\begin{pmatrix}
-3 \\\
2 \\\
0 \\\
a
\end{pmatrix}
{% endkatex %}
## Augmented matrix form
Finally some new UI design of the matrix, looks more elegant this way.
{% katex %}
\left[
\begin{array}{ccccc|c}
-2 & 4 & -2 & -1 & 4 & -3 \\\
4 & -8 & 3 & -3 & 1 & 2 \\\
1 & -2 & 1 & -1 & 1 & 0 \\\
1 & -2 & 0 & -3 & 4 & a
\end{array}
\right]
{% endkatex %}
### Now what?
Now we'll transform the augmented matrix using elementary transformation to becoming a _REF_!
Before we continue, remember! R stands for row and the notation will be Rx -> Ry, which means the value of Rx will be put in row Ry. Now let's continue.
#### Swap R1 and R3
{% katex %}
\overset{R_1 \leftrightarrow R_3}{\left[
\begin{array}{ccccc|c}
1 & -2 & 1 & -1 & 1 & 0 \\\
4 & -8 & 3 & -3 & 1 & 2 \\\
-2 & 4 & -2 & -1 & 4 & -3 \\\
1 & -2 & 0 & -3 & 4 & a
\end{array}
\right]}
{% endkatex %}
#### Multiple Row Multiplication
{% katex %}
\overset{\begin{array}{l}
R_2 - 4R_1 \rightarrow R_2 \\\
R_3 + 2R_1 \rightarrow R_3 \\\
R_4 - R_1 \rightarrow R_4
\end{array}}{\left[
\begin{array}{ccccc|c}
1 & -2 & 1 & -1 & 1 & 0 \\\
0 & 0 & -1 & 1 & -3 & 2 \\\
0 & 0 & 0 & -3 & 6 & -3 \\\
0 & 0 & -1 & -2 & 3 & a
\end{array}
\right]}
{% endkatex %}
#### Subtract R4 with R2 and R3
{% katex %}
\overset{R_4 - R_2 - R_3 \rightarrow R_4}{\left[
\begin{array}{ccccc|c}
1 & -2 & 1 & -1 & 1 & 0 \\\
0 & 0 & -1 & 1 & -3 & 2 \\\
0 & 0 & 0 & -3 & 6 & -3 \\\
0 & 0 & 0 & 0 & 0 & a - 2 + 3
\end{array}
\right]}
{% endkatex %}
#### Scaling
{% katex %}
\overset{\begin{array}{l}
-R_2 \rightarrow R_2 \\\
-\frac{1}{3}R_3 \rightarrow R_3
\end{array}}{\left[
\begin{array}{ccccc|c}
1 & -2 & 1 & -1 & 1 & 0 \\\
0 & 0 & 1 & -1 & 3 & -2 \\\
0 & 0 & 0 & 1 & -2 & 1 \\\
0 & 0 & 0 & 0 & 0 & a + 1
\end{array}
\right]}
{% endkatex %}

### Okay Terra, you made me read all of this complex mumbo jumbo, what do I do now?
First off, you need to relax. Secondly, Given that a+1 = 0 we can create a solution for `a = -1`!
But... I need to confess, the authors didn't provide a step by step solution to their answers :( But I did create one for my solution :D so you be the judge if I'm correct or not by proving it yourselves as well!
#### Particular solution
Remember on the previous chapter we used a type of identity matrix? well, there isn't one here and since on the pages I'm reading on didn't have the steps and only the solution, I'll show you know I did it :D
##### Find Ax = B
{% katex %}
B = \begin{pmatrix}
0 \\\
-2 \\\
1 \\\
0
\end{pmatrix}
{% endkatex %}
and assume that:
{% katex %}
x_1 = a \\\
x_2 = b \\\
x_3 = c \\\
x_4 = d \\\
x_5 = e
{% endkatex %}
We can split the result to form an equation like this, where each x is associated to a specific column.
{% katex %}
\begin{pmatrix}
0 \\\
-2 \\\
1 \\\
0
\end{pmatrix} = a
\begin{pmatrix}
1 \\\
0 \\\
0 \\\
0
\end{pmatrix} + b
\begin{pmatrix}
-2 \\\
0 \\\
0 \\\
0
\end{pmatrix} + c
\begin{pmatrix}
1 \\\
1 \\\
0 \\\
0
\end{pmatrix} + \underbrace{d
\begin{pmatrix}
-1 \\\
-1 \\\
1 \\\
0
\end{pmatrix} + e
\begin{pmatrix}
1 \\\
-3 \\\
-2 \\\
0
\end{pmatrix}}_{\text{Let's focus on this part}}
{% endkatex %}
##### Let's assume that d and e are equal to 1 and add both of these to see what we get
{% katex %}
1
\begin{pmatrix}
-1 \\\
-1 \\\
1 \\\
0
\end{pmatrix} + 1
\begin{pmatrix}
1 \\\
-3 \\\
-2 \\\
0
\end{pmatrix} =
\begin{pmatrix}
0 \\\
2 \\\
-1 \\\
0
\end{pmatrix}
{% endkatex %}
Notice that the result of adding these result in the negative value of the result we're searching for?
{% katex %}
\begin{pmatrix}
0 \\\
2 \\\
-1 \\\
0
\end{pmatrix} = -1
\begin{pmatrix}
0 \\\
-2 \\\
1 \\\
0
\end{pmatrix}
{% endkatex %}
##### Finding d and e
Assume:
{% katex %}
x = \begin{pmatrix}
-1 \\\
-1 \\\
1 \\\
0
\end{pmatrix}
{% endkatex %}
and
{% katex %}
y = \begin{pmatrix}
1 \\\
-3 \\\
-2 \\\
0
\end{pmatrix}
{% endkatex %}
Given:
{% katex %}
dx + ey = -(x + y)
{% endkatex %}
{% katex %}
dx + x + ey + y = 0
{% endkatex %}
{% katex %}
x(d+1) + y(e+1) = 0
{% endkatex %}
Since we know that x and y are not zero, the only way to fulfill this equation is by having (d+1) and (e+1) = 0.
So, both
{% katex %}
d = -1 \quad \text{and} \quad e = -1
{% endkatex %}
#### Particular Solution Result
Great! now we can conclude that the particular solution is:
{% katex %}
x \text{ (My answer)} = \begin{pmatrix}
0 \\\
0 \\\
0 \\\
-1 \\\
-1
\end{pmatrix}
{% endkatex %}
Though... there's a small caveat. This isn't the author's answer, it's mine, I tried finding the solution in the sentences or maybe I slipped a page or two, but I think it's after going in-depth to _row echelon form_ first, so I'm not sure about the method used to solve it.
{% katex %}
x \text{ (Author's answer)} = \begin{pmatrix}
2 \\\
0 \\\
-1 \\\
1 \\\
0
\end{pmatrix}
{% endkatex %}
#### General Solutions
I won't go into depth in this one, considering I also got the answer of Ax = 0 different. For more context, I'm using the same method as the yesterday with the lambda is from column 4 and column 5 (Since only those two contain the most non-zero column) and the column will become -1.
I'm really not sure if this is just math being math or I'm doing something wrong!
##### My answer
{% katex %}
\left\( x \in \mathbb{R}^5 \mid x =
\begin{pmatrix}
0 \\\
0 \\\
0 \\\
-1 \\\
-1
\end{pmatrix} + \lambda_1
\begin{pmatrix}
1 \\\
0 \\\
-\frac{5
}{2} \\\
0 \\\
\frac{1}{2}
\end{pmatrix} + \lambda_2
\begin{pmatrix}
-2 \\\
0 \\\
5 \\\
2 \\\
-1
\end{pmatrix}, \; \lambda_1, \lambda_2 \in \mathbb{R} \right\)
{% endkatex %}
##### Author's answer
{% katex %}
\left\( x \in \mathbb{R}^5 \mid x =
\begin{pmatrix}
2 \\\
0 \\\
-1 \\\
1 \\\
0
\end{pmatrix} + \lambda_1
\begin{pmatrix}
2 \\\
1 \\\
0 \\\
0 \\\
0
\end{pmatrix} + \lambda_2
\begin{pmatrix}
2 \\\
0 \\\
-1 \\\
2 \\\
1
\end{pmatrix}, \; \lambda_1, \lambda_2 \in \mathbb{R} \right\)
{% endkatex %}
### Ending note:
That's the end, I spent too much time racking my brain about the answer and might as well post it since I might get an answer on what kind of behavior is this.

Ok, basically one of my highest viewership posts are all about vs code extensions. So, I wanted to make a really big awesome list about vs code extensions. So, let us get straight into this.
## BETTER COMMENTS ❗
Better comments formats the comments you write in the code as the name suggests. It basically gives you're a code a better readability. Most of the code comments are clutter if you don't write them with a lot spaces. They often blend in with code and this is really frustrating when you have lots and lots of lines of code in your program.
![Img one] (https://dev-to-uploads.s3.amazonaws.com/uploads/articles/nsp0yk9xffcep2f1wgsc.png)
The above image shows how this actually works
## auto rename tags < what ? 😕 >
So let us say, you have put an UL tag instead of li tag. If you want to change that you delete the whole thing and rewrite the code. This is time consuming and a wastage of effort. This is where auto rename tags comes in. It changes both the opening and closing tag's name if you change it one
Here is how it actually works
## Indent rainbow 🌈
If you are a web developer, you know the pain of children tags. They often cause a lot of code mistakes. Indent rainbow is here to clear the clutter and make your code look much better. Use it along prettier, this will definitely make a change.
## Preview images 🖼
If your program has a lot of images in it, you might have faced a problem of putting an image in the wrong area. Preview images is an extension that basically shows a preview of the image beside your code. This makes life with images much easier
## Luna paint 🎨
Want to crop or make a last-minute edit to your image. Instead of opening the image editor and making the changes. And then again export the image and replace it with the old image. Hope, we had an inbuilt photo editor in vs code. Yes, we do have a photo editor inside vs code. It's called luna paint. You should definitely have this extension in vs code.
## END !
Thanks guys for reading. Hope you liked this ! See you in the next one
peace ✌

From today we will discuss all the topics of our web programming.
**Today's topic is: What is HTML?**
The full name of HTML is (Hyper Text Markup Language).It is a good language for creating web pages.
The concept of HTML was first developed by Tim Berners-Lee. He proposed the basic idea of HTML in 1989 while working at CERN (European Organization for Nuclear Research). He wanted to create a simple markup language that would help share information. HTML 1.0 was released in 1993. It was a very simple language with some basic tags. HTML 2.0 was released in 1995. This version added several new tags and features that made it easier. HTML 3.2 was released in 1997 and brought some new features such as tables, applets, and styling tags. At this time the World Wide Web Consortium (W3C) began to regulate the development of HTML. HTML 4.0 was released in the same year and added many new features such as style sheets, scripts and more. Accessibility and internationalization are also improved in HTML 4.0. HTML 4.01 was released in 1999 and is an updated version of HTML 4.0 that brings some bug fixes and minor improvements. In 2000, XHTML 1.0 was released, based on HTML 4.01 and compatible with XML. XHTML follows stricter syntax rules. HTML5 was released as a stable version in 2014 after a long development and discussion. It brings many new features such as new tags, audio and video embedding, canvas element, and more.
HTML5 makes web application development more powerful. Through HTML, various parts of the web page such as Heading, paragraph, List, table, img, and other elements can be defined. Each element is composed using separate tags, which define the structure of the page. Most popular web browsers (such as Chrome, Firefox, Safari, and Edge) support HTML. It is a standard markup language that works in all browsers and appears the same.
HTML is still in development and is established as an essential language for web development. This was today's short topic on HTML history. Tomorrow I will talk about how to use HTML.

1,921,270 | Data Types | Every value in Rust is of a certain data type, which tells Rust what kind of data is being specified... | 28,032 | 2024-07-12T14:29:48 | https://dev.to/danielmwandiki/data-types-1dp3 | learning, rust, devops | Every value in Rust is of a certain data type, which tells Rust what kind of data is being specified so it knows how to work with it.
*Scalar data type*: Types that store only a single value.
*Compound data type*: Types that store multiple values, even values of different types.
###Scalar Types
Rust has four primary scalar types: integers, floating-point numbers, Booleans, and characters.
####Integers
Integers refer to whole numbers. Integers in Rust are either Signed or Unsigned. Unsigned integers store only 0 and positive numbers, while Signed integers can store negative numbers, 0 and positive numbers.
Following are the available Integer types based on the sign and length:
Each signed variant can store numbers from -(2<sup>n - 1</sup>) to 2<sup>n - 1</sup> - 1 inclusive, where n is the number of bits that the variant uses. Unsigned variants can store numbers from 0 to 2<sup>n</sup> - 1.
Here is an example of an integer:
```
fn main() {
let x :u8 = "42"; // 8bit
let x :i16 = "21"; // 16 bit
let x :u32 = "43"; // 32 bit
let x :i64 = "32"; //64 bit
let x :u128 = "72"; // 128 bit
let x :usize = "98"; // depend on the architecture of the computer
}
```
####Floating point numbers
Floating point numbers, more commonly known as float(s), are a data type that holds numbers that have a fractional value (something after the decimal point). Rust's floating-point types are `f32` and `f64`, 32 bits and 64 in size, respectively.
Here is an example that shows floating-point numbers:
```
fn main() {
let x = 2.0; // f64
let y: f32 = 3.0; // f32
}
```
####Characters
You can store a single character in a variable, and the type is `char`. Like traditional programming languages of the 80s, you can store an ASCII character. But Rust also extends the character type to store a valid UTF-8 character. This means that you can store an emoji in a single character 😉
Here is an example:
```
fn main() {
let a = 'a';
let p: char = 'p'; // with explicit type annotation
let crab = '🦀';
}
```
####Booleans
The boolean type in Rust stores only one of two possible values: `true` or `false`. If you wish to annotate the type, use `bool` to indicate the type.
Here is an example:
```
fn main() {
let t = true;
let f: bool = false; // with explicit type annotation
}
```
###Compound Types
Compound data types can store multiple values in a variable. These values may be of the same scalar data type or different scalar types. Rust has two primitive compound types: *tuples and arrays*.
####The Tuple Type
A tuple stores multiple values, either of the same type or even of different types. Once declared, they cannot grow or shrink in size. We create a tuple by writing a comma-separated list of values inside parentheses.
Here is an example:
```
fn main() {
let tup: (i32, f64, u8) = (500, 6.4, 1);
}
```
####The Array Type
The Array Type stores multiple values of the same type. Unlike arrays in some other languages, arrays in Rust have a fixed length. We write the values in an array as a comma-separated list inside square brackets:
```
fn main() {
let a = [1, 2, 3, 4, 5];
}
```

But what exactly is Vector Search, and how can it benefit your business? Let’s unpack this innovation and explore its potential.
What is Vector Search? 🔍
Vector Search is a method of searching through data by comparing vectors, which are essentially arrays of numbers representing different features of data. Unlike traditional search methods that rely on keyword matching, Vector Search allows for more nuanced and context-aware retrieval of information. This means that you can find similar items based on their features, not just exact keyword matches.
How Does It Work with Amazon MemoryDB? 🛠️
Amazon MemoryDB is a Redis-compatible, fully managed, in-memory database service that delivers ultra-fast performance. The integration of Vector Search into MemoryDB leverages the power of in-memory data storage, making searches incredibly fast and efficient.
The architecture supporting this feature includes:
1) Redis Data Structures: MemoryDB uses Redis data structures, which are optimized for high performance and low latency.
2) In-Memory Storage: By keeping data in memory, MemoryDB ensures that searches and data retrieval are executed with minimal delay.
Vector Embeddings: These are mathematical representations of data points that enable the comparison of complex data features.
Benefits for Enterprise Customers 🌟
One of the key advantages of Vector Search is enhanced search accuracy. By allowing searches to be based on contextual relevance rather than simple keyword matches, it significantly improves the precision of search results. This is particularly useful for enterprises dealing with large and complex datasets.
Real-time data processing is another critical benefit. Thanks to MemoryDB's in-memory capabilities, search operations are performed instantly, providing immediate results and insights. This feature is especially beneficial for applications requiring rapid data retrieval and processing.
Scalability and flexibility are also major advantages. As a fully managed service, MemoryDB enables enterprises to scale their operations smoothly without worrying about the underlying infrastructure. This makes it easier to handle increasing data volumes and evolving business needs.
Moreover, Vector Search contributes to a better user experience. Applications such as recommendation engines or personalized content delivery systems benefit from the refined and user-friendly search capabilities provided by this feature. By understanding the underlying features of the data, these applications can offer more relevant and engaging results to users.
Use Cases 🏢
E-commerce platforms can enhance product recommendations by finding items similar to those a user has interacted with, based on features rather than keywords. In fraud detection, patterns in transaction data that may indicate fraudulent activity can be identified even if they don’t match previous examples exactly.
For content personalization, Vector Search allows for delivering personalized content to users by understanding the underlying features of the data they engage with.
Conclusion 🎯
The general availability of Vector Search for Amazon MemoryDB marks a significant advancement for enterprises looking to harness the power of their data more effectively. By enabling faster, more accurate, and context-aware search capabilities, this feature helps businesses improve their operations and user experiences.

1,921,274 | Databases Deconstructed: The Value of Data Lakehouses and Table Formats | Checkout out my Apache Iceberg Crash Course Get a free copy of Apache Iceberg the Definitive... | 0 | 2024-07-12T14:36:49 | https://dev.to/alexmercedcoder/databases-deconstructed-the-value-of-data-lakhoues-and-table-formats-32en | database, dataengineering, datascience, data | - [Checkout out my Apache Iceberg Crash Course](https://bit.ly/am-2024-iceberg-live-crash-course-1)
- [Get a free copy of Apache Iceberg the Definitive Guide](https://bit.ly/am-iceberg-book)
Databases and data warehouses are powerful systems that simplify working with data by abstracting many of the inherent challenges, including:
- **Storage:** How data is stored and persisted, what file formats are used, and how those files are managed.
- **Tables:** How we determine which data belongs to which table and what table statistics are tracked internally.
- **Catalog:** How the system keeps track of all the tables so that users can easily access them.
- **Processing:** When a user writes a query, how that query is parsed into relational algebra expressions, transformed into an execution plan, optimized, and executed.
The drawback of having such tightly coupled systems is that the data within them is only understood by that specific system. Therefore, if another system is needed for a particular use case, the data must be migrated and duplicated into that other system. While this is often manageable for transactions (e.g., adding a user, updating a user, recording a sale) as a single database system can handle all CRUD operations (Create, Read, Update, Delete), it becomes more problematic in analytics. Analytical use cases are far more diverse, as are the tools required to support them, making data migration and duplication cumbersome and inefficient.
## Enter the Lakehouse
In analytics, the status quo has been to duplicate your data across multiple systems for different use cases:
- **Data Lakes:** A universal storage layer for structured data in the form of CSV, JSON, ORC, AVRO, and Parquet files, as well as all other unstructured data like images, videos, and audio. Data lakes are often used as a repository for archiving all data and as a place to store the diverse data needed for training AI/ML models that require both structured and unstructured data.
- **Data Warehouses:** Essentially databases designed for analytics. They store and manage structured data with analytics in mind and are usually used as the data source for reports and Business Intelligence dashboards (visual panes built directly on the data).
In an ideal world, you wouldn't need the costs and complexity of duplicating your data across systems and figuring out how to keep it all consistent. This is where the data lakehouse pattern comes in. The data lakehouse is an architectural pattern that essentially builds a deconstructed database using your data lake as the storage layer. The benefit is that structured data can now exist once in your data lake, and both data lakehouse tools and data warehouse tools can access it.
Let's examine the construction of a data lakehouse layer by layer.
## The Storage Layer
The basic foundation of a data lakehouse is the storage layer, where we need to determine where and how to store the data. For the "where," the obvious choice is object storage.
**What is Object Storage?**
Object storage is a data storage architecture that manages data as objects, as opposed to file systems that manage data as a file hierarchy, or block storage which manages data as blocks within sectors and tracks. Each object includes the data itself, a variable amount of metadata, and a unique identifier. This approach is highly scalable, cost-effective, and suitable for handling large amounts of unstructured data.
**Benefits of Object Storage:**
- **Scalability:** Object storage can easily scale out by adding more nodes, making it suitable for growing data needs.
- **Durability and Reliability:** Data is stored redundantly across multiple locations, ensuring high durability and reliability.
- **Cost-Effectiveness:** Often cheaper than traditional storage solutions, especially when dealing with large volumes of data.
- **Metadata Management:** Object storage allows for rich metadata, enabling more efficient data management and retrieval.
We can opt for major cloud vendors like AWS, Azure, and Google Cloud. However, many other storage vendors, such as [NetApp, Vast Data, MinIO, and Pure Storage, provide additional value in object storage solutions](https://www.dremio.com/blog/3-reasons-to-create-hybrid-apache-iceberg-data-lakehouses/) both in the cloud and on-premises.
Next, we need to determine how we will store the data on the storage layer. The industry standard for this is Apache Parquet files.
**What are Apache Parquet Files?**
Apache Parquet is a columnar storage file format optimized for use with big data processing frameworks. It is designed for efficient data storage and retrieval, making it ideal for analytic workloads.
**Why Parquet Files are Good for Analytics:**
- **Efficiency:** Parquet's columnar storage layout allows for efficient data compression and encoding schemes, reducing the amount of data scanned and improving query performance.
- **Compatibility:** Parquet is widely supported by many data processing tools and frameworks, making it a versatile choice for data storage.
**How Row Groups Work in Parquet:**
Parquet files are divided into row groups, subsets of the data that can be processed independently. Each row group contains column chunks, each of which consists of pages. This structure enables efficient reads by allowing queries to skip irrelevant data and read only the necessary columns and rows.
```
+-----------------------------------------------------+
| Parquet File |
+-----------------------------------------------------+
| File Metadata |
| |
| - Schema |
| - Key-Value Metadata |

By establishing a robust storage layer with object storage and using Apache Parquet files for data storage, we create a strong foundation for our data lakehouse. This setup ensures scalability, efficiency, and compatibility, essential for handling diverse and extensive data analytics workloads.
## The Table Format
While Parquet files are excellent for storing data for quick access, datasets can eventually grow large enough to span multiple files. Parquet files are only aware of themselves and are unaware of other files in the same dataset. This puts the analyst responsible for defining the dataset, which can lead to mistakes where a file isn't included or extra files are included, resulting in inconsistent data definitions across use cases. Additionally, engines still need to open every file to execute a query, which can be time-consuming, especially if many files aren't needed for the specific query.
In this case, we need an abstraction that helps do a few things:
- Define which files comprise the current version of the table.
- Maintain a history of the file listings for previous table versions.
- Track file statistics that can be used to determine which files are relevant to a particular query.
This abstraction allows for faster scanning of large datasets and consistent results. It is known as a "table format," a standard for how metadata is written to document the files in the table along with their statistics.
Currently, there are three main table formats: [Apache Iceberg, Apache Hudi, and Delta Lake](https://bit.ly/am-format-arch).
[Apache Iceberg is thought to have recently established itself as the industry standard.](https://blog.iceberglakehouse.com/summarizing-recent-wins-for-apache-iceberg-table-format-56bd60837181?source=collection_home---4------3-----------------------)
## The Catalog
Now that we have folders with metadata and data that comprise a table, processing tools need a way to know these tables exist and where the metadata for each table can be found. This is where the lakehouse catalog comes into play. A lakehouse catalog can perform several functions:
- **Track Tables:** Keep track of which tables exist in a data lakehouse.
- **Metadata References:** Provide references to the current metadata of each table.
- **Access Governance:** Govern access to the assets it tracks.
The catalog becomes the mechanism for bundling your tables and making them accessible to your preferred data processing tools. Currently, there are four main lakehouse catalogs offering solutions for this layer:
- **Nessie:** An open-source catalog that offers unique catalog-level versioning features for git-like functionality, initially created by Dremio.
- **Polaris:** An open-source catalog created by Snowflake.
- **Unity OSS:** An open-source catalog from Databricks, which is a complete rewrite of their proprietary Unity catalog.
- **Gravitino:** An open-source catalog from Datastrato.
You can efficiently manage and access your data lakehouse tables by leveraging these catalogs, ensuring seamless integration with various data processing tools.
## Data Processing
Now that we have everything needed to store and track our data, we just need a tool to access that data and run queries and transformations for us. One such tool is [Dremio, a data lakehouse platform](https://www.dremio.com/solutions/data-lakehouse/) created to make working with data lakehouses easier, faster, and more open.
### Dremio provides:
- **Unified Analytics:** The ability to connect to data lakes, lakehouse catalogs, databases, and data warehouses, allowing you to work with all your data in one place.
- **SQL Query Engine:** An SQL query engine with industry-leading price/performance that can federate queries across all these data sources, featuring a semantic layer to track and define data models and metrics for fast reporting and business intelligence (BI).
- **Lakehouse Management:** Dremio has deep integrations with Nessie catalogs and an integrated lakehouse catalog that allows you to automate the maintenance of Iceberg tables, ensuring your data lakehouse runs smoothly.
Dremio becomes a powerful tool for unifying and organizing your data into data products for your users. Since your data is in a lakehouse, several tools can be part of the picture. For example, you can use Upsolver, Fivetran, or Airbyte to ingest data into your lakehouse, run graph queries on your lakehouse with Puppygraph, and explore many other possibilities—all without needing multiple copies of your data.
## Conclusion
We've deconstructed the traditional database and data warehouse systems to highlight the value of data lakehouses and table formats. Databases and data warehouses simplify working with data by abstracting many inherent challenges, such as storage, table management, cataloging, and query processing. However, the tightly coupled nature of these systems often necessitates data duplication across different systems, leading to increased complexity and inefficiency.
The data lakehouse architecture emerges as a solution, offering the best of both data lakes and data warehouses. By leveraging object storage and Apache Parquet files, we establish a robust storage layer that ensures scalability, efficiency, and compatibility. The introduction of table formats like Apache Iceberg, Apache Hudi, and Delta Lake further enhances our ability to manage large datasets effectively.
To manage and track our data, lakehouse catalogs like Nessie, Polaris, Unity OSS, and Gravitino provide essential functionalities such as tracking tables, providing metadata references, and governing access. Finally, tools like Dremio offer potent data processing capabilities, enabling unified analytics, efficient query execution, and seamless lakehouse management.
By adopting a data lakehouse architecture, we can streamline data management, reduce costs, and accelerate time to insight, all while maintaining the flexibility to integrate various tools and technologies.

谷歌引流自动注册,技术的双刃剑
在当今信息化社会，谷歌引流自动注册技术日益引起关注。这项技术利用自动化程序，大量注册谷歌账号，并通过这些账号执行各种操作，从而实现特定目的。尽管这种技术在某些领域具有潜在的实用性，但其背后也存在着伦理、法律和安全等多重挑战。
技术原理与应用
谷歌引流自动注册依赖于自动化软件或脚本，通过模拟人工操作，快速生成大量的谷歌账号。这些账号可以用于自动化执行搜索、评论、点赞等操作，以此来提高特定内容的曝光度或影响力。在数字营销领域，这种技术被用来增加网站的流量，提升搜索引擎排名，或者扩大社交媒体影响力。
伦理和法律问题
然而，谷歌引流自动注册也引发了一系列严重的伦理和法律问题。首先，大规模注册账号可能违反谷歌的服务条款，因为这些行为通常被视为滥用谷歌的服务。其次，自动化操作可能导致信息的虚假扩散，损害信息的真实性和网民的信任度。此外，过度使用自动化程序可能会对网络生态和用户体验造成负面影响，例如垃圾信息增加、系统负载增加等问题。
安全风险
除了伦理和法律问题外，谷歌引流自动注册也存在显著的安全风险。大量的虚假账号不仅可能被用于恶意目的，如网络欺诈、信息泄露等，还可能成为黑客攻击的潜在入口。通过这些账号，黑客可以进行钓鱼攻击、账号盗窃等行为，威胁到个人和企业的信息安全。
监管和防范措施
为了应对谷歌引流自动注册带来的种种问题，监管部门和技术公司需要共同努力。首先，加强对自动化程序的监控和识别能力，及时发现和阻止非法活动。其次，加强对用户身份的验证和账号管理制度，减少虚假账号的生成和滥用。此外，提高公众的网络素质和安全意识，引导用户理性使用网络资源，也是解决这一问题的关键。
总体而言，谷歌引流自动注册技术在提升效率和影响力方面具有潜在优势，但其合法性和安全性仍然是亟待解决的难题。只有通过技术创新和规范管理，才能有效平衡技术发展和社会责任，为数字化时代的发展注入更多正能量。

Ne ovat helppokäyttöinen ja mukautuva kulkuneuvo kaikenikäisille – niin nuorille kuin vanhemmillekin. Parhaimmillaan sähköpyörä auttaa sinua kohti aktiivisempaa ja terveellisempää elämää. Tutustutaanpa tarkemmin, kuinka sähköpyörät voivat parantaa elämänlaatua ja tehdä arjen liikkumisesta entistä vaivattomampaa.
Helppokäyttöinen ja mukautuva tapa liikkua
Sähköpyörä on varustettu akkukäyttöisellä sähkömoottorilla, joka tarjoaa apua polkemiseen juuri silloin, kun sitä eniten tarvitset. Voit säätää moottorin avustusta helposti ohjaustankoon kiinnitetystä näytöstä juuri niin paljon kuin haluat. Tämä on erityisen hyödyllistä esimerkiksi jyrkissä mäissä tai silloin, kun kuljetat ostoksia pyörän korissa. Pyörän näyttö kertoo myös akun varauksen ja kantaman, joten tiedät aina, kuinka pitkälle voit ajaa ennen seuraavaa latausta.
Liikkumisen vapautta ja hyvinvointia
Sähköpyöräily tarjoaa erinomaisen tavan pysyä aktiivisena ja nauttia ulkoilmasta. Liikunta on tunnetusti tärkeää kaikenikäisille, ja sähköpyörä mahdollistaa fyysisen aktiivisuuden ilman liiallista rasitusta nivelille ja lihaksille. Sähköpyöräily on loistava keino parantaa sydän- ja verenkiertoelimistön terveyttä sekä lisätä yleistä hyvinvointia. Voit itse säätää rasituksen tasoa moottorin avustuksen avulla, jolloin pyöräily on aina mukavaa ja sopii omaan kuntoon ja tarpeisiin. Mikä parasta, saat pyörän selässä aimo annoksen raitista ilmaa ja pääset nauttimaan ulkoilusta vaikka ympäri vuoden.
Ympäristöystävällinen ja taloudellinen valinta
Sähköpyörä on ympäristöystävällinen vaihtoehto autolle, erityisesti lyhyillä matkoilla – ja miksei myös pidempien reissujen taittamiseksi. Se on hiljainen kulkuväline, joka ei autojen tapaan tuota päästöjä, tehden siitä miellyttävän valinnan sekä ympäristölle että naapurustolle. Sähköpyöräilyn myötä voit säästää myös rahaa, kun polttoainekustannukset ja auton huoltokulut vähenevät. Lisäksi sähköpyörällä liikkuminen on usein nopeampaa ja kätevämpää, sillä vältyt ruuhkilta ja pysäköintiongelmilta.
Turvallinen ja luotettava
Matalarunkoinen pyörämalli on erinomainen valinta päivittäiseen liikkumiseen. Pyörän muotoilun ansiosta satulaan nousemisen ja siltä laskeutumisen on helppoa ja turvallista. Ajamisen helppous ja saavutettavuus on tärkeää niin nuorille kuin vanhemmillekin pyöräilijöille. Pysäköinti on helppoa, kun voit halutessasi ottaa pyörän akun matkaan silloin, kun et aja pyörällä.
Pyöräily on sosiaalinen ja yhteisöllinen harrastus
Sähköpyöräily ei ole vain liikuntamuoto, vaan myös mainio tapa viettää aikaa ystävien ja perheen kanssa ulkoillen. Voit lähteä yhteisille pyöräretkille tai tavata uusia ihmisiä, jotka jakavat saman kiinnostuksen pyöräilyyn. [Sähköpyörän](https://dev.to/users) avulla pysyt helposti mukana ryhmän vauhdissa, vaikka fyysinen kuntosi ei olisikaan vielä samalla tasolla kuin kokeneemmilla pyöräilijöillä.
**Monipuoliset käyttömahdollisuudet**

Reddit自动群组群发的现象与影响
Reddit作为全球最大的社交新闻平台之一，其独特的社区结构和内容分享机制，吸引了数以百万计的用户参与讨论、分享和互动。然而，近年来，Reddit上出现了一种新的现象，即自动群组群发。
自动群组群发是什么？
自动群组群发是指通过编写脚本或使用自动化工具，在Reddit上自动发布内容到多个群组（Subreddit）的行为。这些工具可以让用户在几秒钟内将同一篇内容或链接同时发布到数十个甚至上百个群组，从而迅速扩大内容的曝光和影响力。
现象背后的原因
曝光和流量增加需求,许多用户或内容创作者希望他们的帖子能够获得更多的曝光和流量，以增加讨论和参与度。
时间和效率考虑,手动逐一发布到多个群组耗时耗力，自动化工具可以节省大量时间和精力。
算法和排名影响,一些用户认为通过多个群组的同时发布，可以影响Reddit的算法排名，使其在主页或热门页面更容易被看到。
影响与问题
内容质量下降,大量自动群发可能导致部分群组中出现重复或低质量的内容，影响用户体验和群组的内容质量。
群组规则遭遇挑战,自动化工具发布的内容可能违反特定群组的规则，如主题不符或过于频繁的发布。
社区反感和抵制,一些Reddit用户和管理员可能会对自动群组群发表示反感，认为其破坏了社区的自然互动和内容选择过程。
管理与应对策略
技术层面的应对,Reddit平台可以通过技术手段检测和限制自动化工具的使用，确保内容的多样性和质量。
用户教育与规范,Reddit可以通过教育用户，强调手动发布与自动化发布的区别，并促使用户遵守群组的规则和社区准则。
平台治理与监管,Reddit社区管理员和志愿者可以加强对群组的管理和监督，及时处理违规内容和行为。
结论
Reddit自动群组群发是一个充满争议的现象，既有其便利性和效率，也带来了内容质量和社区规则遵守等一系列问题。平台和用户需要共同努力，寻找合适的平衡点，以保持Reddit作为开放而又高质量的内容交流平台的特性和魅力。
通过更好地理解和应对自动群组群发现象，Reddit可以进一步提升其社区的健康性和可持续性，确保所有用户都能够在公平、开放的环境中分享和交流他们的观点和创意。

1,921,290 | Mastering Database Merging: Comparing Different Approaches | In today’s world, managing data efficiently is crucial for businesses. One key task in data... | 0 | 2024-07-12T14:58:40 | https://dev.to/andreaslennartz/mastering-database-merging-comparing-different-approaches-3ggf | csharp, etl, database, sql | In today’s world, managing data efficiently is crucial for businesses. One key task in data management is merging new data into existing database tables. Whether you’re adding new information or updating existing records, knowing how to do this properly can make a big difference. However, this task can be complex, and there are various approaches and paradigms you should be aware of.
## Basic Example Scenario
Let's start with an example. Imagine you have a table called `customers` with the following columns:
- `customer_id`
- `name`
- `email`
And the following data:
| customer_id | name | email |
|-------------|------------|----------------------|
| 1 | John Doe | john.doe@example.com |
| 2 | Jane Smith | xx |
| 3 | Bob Brown | bobbrown@mail.com |
You receive a new batch of data with these changes:
| customer_id | name | email |
|-------------|---------------|----------------------|
| 1 | John Doe | john.doe@example.com |
| 2 | Jane Smith | jane.smith@example.com |
| 4 | Alice Johnson | alice.j@example.com |
Your goal is to merge this new data with the existing `customers` table. As a result of the merge operation, you want the incoming data to be integrated into the target table. This will result in one insertion of a new record (Alice Johnson), one update (email of Jane Smith), and one deletion (Bob Brown). The record for John Doe should be left untouched, as nothing has changed for this record.
Note that this example uses only a small number of rows. In real-world scenarios, you will need to deal with a very high volume of changes (e.g., up to millions per day). In the following sections, we will focus on solutions that can handle large volumes of data.
### Using a Staging Table
First, we create and insert the existing data into the `customers` table:
```sql
CREATE TABLE customers (
customer_id INT NOT NULL PRIMARY KEY,
name VARCHAR(100),
email VARCHAR(100)
);
INSERT INTO customers (customer_id, name, email)
VALUES
(1, 'John Doe', 'john.doe@example.com'),
(2, 'Jane Smith', 'xx'),
(3, 'Bob Brown', 'bobbrown@mail.com');
```
To simplify this example, we currently do not take into account how we receive this data. For now, we will insert the new data into a staging table:
```sql
CREATE TABLE staging_customers (
customer_id INT,
name VARCHAR(100),
email VARCHAR(100)
);
INSERT INTO staging_customers (customer_id, name, email) VALUES
(1, 'John Doe', 'john.doe@example.com'),
(2, 'Jane Smith', 'jane.smith@example.com'),
(4, 'Alice Johnson', 'alice.j@example.com');
```
### SQL Example for Inserts and Updates
You can use the `MERGE` statement to perform an Insert or Update (a.k.a. UPSERT) operation. The `MERGE` statement is supported by many databases like SQL Server, PostgreSQL, and Oracle. Note that this requires the data from your source to be loaded into a staging table first.
```sql
MERGE INTO customers AS target
USING staging_customers AS source
ON target.customer_id = source.customer_id
WHEN MATCHED THEN
UPDATE SET name = source.name, email = source.email
WHEN NOT MATCHED THEN
INSERT (customer_id, name, email)
VALUES (source.customer_id, source.name, source.email);
```
Running this `MERGE` statement will automatically perform the necessary insert and update operations. Note that this process does not handle deletions. Keep in mind that the first record will be updated even if the input data matches the existing data in the destination table.
#### UPSERT Example for MySQL/MariaDB
In databases like MySQL or MariaDB that don't support the `MERGE` statement, you can use an `INSERT ... ON DUPLICATE KEY UPDATE` statement for upserts:
```sql
INSERT INTO customers (customer_id, name, email)
SELECT customer_id, name, email FROM staging_customers
ON DUPLICATE KEY UPDATE
name = VALUES(name),
email = VALUES(email);
```
Please note that `customer_id` is the primary key of the `customers` table. This is a prerequisite for the SQL above to work, as the primary key is automatically determined as the key column for the `ON DUPLICATE KEY` operation.
### Handling Deletes
To handle deletions, you need to identify rows that exist in the target table but not in the source. This can be achieved using a `WHERE ... NOT IN` statement.
```sql
DELETE FROM customers
WHERE customer_id NOT IN (
SELECT customer_id FROM staging_customers
);
```
As a result, the `customers` table will now look like our input data:
| customer_id | name | email |
|-------------|---------------|----------------------|
| 1 | John Doe | john.doe@example.com |
| 2 | Jane Smith | jane.smith@example.com|
| 4 | Alice Johnson | alice.j@example.com |
Depending on your database, there may be more elegant solutions to solve this. For some databases like SQL Server, the `MERGE` statement does support the `WHEN NOT MATCHED BY SOURCE THEN DELETE` statement, which would also include the delete operation. Or you could use a `LEFT JOIN` instead of a `WHERE ... NOT IN` to determine the records for deletions, which could result in a shorter execution time.
## Importing Data
In the previous example, we assumed that our data magically appeared in our staging table. But in real-world scenarios, we often have to deal with different kinds of data sources from which we are expected to retrieve our data. Let's examine how we can import the data into our database.
### Using `BULK INSERT` for SQL Server
Databases are often limited when importing large amounts of data. By default, most databases offer some form of CSV import. When using the database approach, you are limited to CSV files and to a specific location of the files, making it complicated if your data can't be copied onto the database server. For SQL Server, you can import CSV file data using the `BULK INSERT` statement.
Here is an example of loading a CSV file using `BULK INSERT` in SQL Server:
```sql
BULK INSERT customers
FROM '\data\customers.csv'
WITH (
FIELDTERMINATOR = ',',
ROWTERMINATOR = '\n'
);
```
### Data Cleansing
Besides the limitation to have data available in a CSV format, the examples above also rely on a cleansed staging table, where all data is error-free and can be merged into the destination table. The `MERGE` (or UPSERT) statements are ACID operations, meaning they are all-or-nothing: either all data is merged, or none is. If there's a flawed record in your data, the entire operation will stop, and identifying the flawed row can be challenging, as error messages typically don't specify which row(s) caused the issue.
To make this work, it is necessary that all data is cleaned before being loaded into the target table (e.g., all duplicates removed, etc.). Additionally, importing various data types (e.g., XML from a web service) can complicate the process. Therefore, it makes sense to clean and enrich the data before loading it into the staging table.
### ETL Code with C#
To load data from any source into the target table, you can use ETL data flows. ETL (Extract, Transform, Load) jobs are commonly used to clean and enrich data before loading it into the database. This approach allows you to define your own pipelines, through which your data is processed before it is written into your target table. Using an ETL approach, you can use any source and are not limited to CSV files.
A simple way to create an [ETL pipeline with C# is to use the library ETLBox](https://www.etlbox.net/?utm_source=devto&utm_content=merge). Here is an example of ETLBox loading CSV data into the staging database table using `CsvSource` and `DbDestination`. After the pipeline has run, we can execute our `MERGE` statement.
#### ETL into Staging Table
When creating ETL with C#, you can load the cleansed data into the staging table and then run the `MERGE` statements, or you can directly use the `DbMerge`. Here is an example with the `MERGE` statement:
```csharp
public class CustomerRow
{
[ColumnMap("customer_id")]
[IdColumn]
public int CustomerId { get; set; }
[ColumnMap("name")]
public string Name { get; set; }
[ColumnMap("email")]
public string Email { get; set; }
}
// Data flow definition
var dbConnection = new SqlConnectionManager("..connection string here...");
var source = new CsvSource<CustomerRow>("data/customers.csv");
var cleanData = new RowTransformation<CustomerRow, CustomerRow>(row => {
row.Email = row.Email.Trim().ToLower();// Custom data cleaning logic here
return row;
});
var staging = new DbDestination<CustomerRow>(dbConnection, "staging_customers");
// Linking & executing the data flow
source.LinkTo(cleanData);
cleanData.LinkTo(staging);
Network.Execute(source);
// Running the MERGE operation
SqlTask.Execute(dbConnection, @"
MERGE INTO customers AS target
USING staging_customers AS source
ON target.customer_id = source.customer_id
WHEN MATCHED THEN
UPDATE SET name = source.name,
email = source.email
WHEN NOT MATCHED THEN
INSERT (customer_id, name, email)
VALUES (source.customer_id, source.name, source.email);
");
```
#### ETL with DbMerge
[ETLBox](https://www.etlbox.net/?utm_source=devto&utm_content=merge) already has a built-in `DbMerge` feature. Here is an example of loading data from a `CsvSource`, cleaning it using custom code in a `RowTransformation`, and then merging the cleaned data using `DbMerge`:
```csharp
public class CustomerRow : MergeableRow
{
[ColumnMap("customer_id")]
[IdColumn]
public int CustomerId { get; set; }
[ColumnMap("name")]
public string Name { get; set; }
[ColumnMap("email")]
public string Email { get; set; }
}
// Defining the data flow
var dbConnection = new SqlConnectionManager("..connection string here...");
var source = new CsvSource<CustomerRow>("data/customers.csv");
var cleanData = new RowTransformation<CustomerRow, CustomerRow>(row => {
row.Email = row.Email.Trim().ToLower();// Custom data cleaning logic here
return row;
});
var dbTypeCheck = new DbTypeCheck<CustomerRow>(dbConnection, "customers");
var merge = new DbMerge<CustomerRow>(dbConnection, "customers");
merge.BatchSize = 2000;
var typeErrors = new JsonDestination<CustomerRow>("type_errors.json");
var errorDest = new JsonDestination<ETLBoxError>("other_errors.json");
// Linking
source.LinkTo(cleanData);
cleanData.LinkTo(dbTypeCheck);
dbTypeCheck.LinkTo(merge);
// Error handling
dbTypeCheck.LinkFlawedTo(typeErrors);
merge.LinkErrorTo(errorDest);
// Executing the network
Network.Execute(source);
```
Please note that we no longer use the `MERGE` statement. The `DbTypeCheck` will verify all incoming data for compatibility with the target table before forwarding the rows to the target. Flawed rows will be written into the `type_errors.json` file. Even though we have cleaned and type-checked our data, there could still be issues when we (bulk) insert/update/delete our data in our destination. For performance reasons, this will happen in batches. Due to the ACID nature of the bulk operation, a batch can still fail - these failed batches are forwarded into `other_errors.json`. But instead of rejecting the whole batch (like in the previous `MERGE` statement), we now only reject a small batch of 2000 rows (defined in the `BatchSize` property).
#### Database Transactions
Of course, you could still spin up a database transaction for the whole operation when creating the connection:
```csharp
var dbConnection = new SqlConnectionManager("..connection string here...");
dbConnection.BeginTransaction();
```
If an error occured, you could simply call `dbConnection.Rollback()` (e.g. in a `try/catch` block) and revert your changes.
## Performance Improvements
Handling large amounts of data can make importing and merging complex. While the example provided involves only a few records, real-world scenarios often require dealing with vast amounts of data. Using a simple loop to detect each change and generate individual insert, update, or delete statements would be inefficient and result in poor performance. We need methods optimized for batch-processing large amounts of data.
Sophisticated methods such as batch processing, bulk operations, or specialized tools like ETL (Extract, Transform, Load) frameworks are necessary. These approaches handle large volumes of data efficiently by minimizing the number of database hits, grouping multiple operations into fewer transactions, and greatly enhancing performance and scalability.
### Using Smaller Batches
The merge operation on the database is powerful, but if you have, for example, 1 million rows that need to be changed in an even larger table, the merge may become too slow. In such cases, it is better to process the incoming data in smaller batches. Using an ETL approach allows us to reduce the number of rows per batch (e.g., to 10,000 or 1,000 rows per operation), which reduces the load on the database and improves performance.
### Full Load vs. Delta Load
Another important step to improve performance is to reduce the amount of data that actually needs to be loaded. When integrating data, you can either perform a full load or a delta load.
- **Full Load**: Replaces all the data in the target table with the new data. This method is simple to implement and ensures data consistency, but it can be slow and resource-intensive, especially for large datasets.
- **Delta Load**: Applies only the changes (inserts, updates, deletes) since the last load. This method is faster and less resource-intensive but more complex to implement because it requires tracking changes.
Switching from a full load to a delta load can significantly reduce the load time.
But how can a delta load be established with a data source? The following section will show examples of how this can be introduced to another database table as a data source, but similar strategies can be applied to other types of data sources as well.
#### Change Data Capture (CDC)
CDC is a technique used to identify changes in a database. It captures insert, update, and delete operations on tables and can be very useful for delta loads. When your source is a database, CDC can help by automatically tracking changes. Many databases support CDC, which can be set up to log changes in a separate table.
If you have CDC enabled on your `source_customers` table, you might have a change table like this:
| customer_id | operation | name | email | change_time |
|-------------|-----------|---------------|-----------------------|--------------------|
| 1 | U | John Doe | john.doe@example.com | 2024-07-08 10:00:00|
| 2 | I | Jane Smith | jane.smith@example.com| 2024-07-08 10:05:00|
| 3 | D | Alice Johnson | alice.j@example.com | 2024-07-08 10:10:00|
- with **I** for Insert, **U** for Update and **D** for Delete.
You can use this change table to apply only the changes to your target table.
For example, we can create an ETL database source like this:
```csharp
var lastLoadDate = DateTime.Now().AddDays(-1);
var source = new DbSource<CustomerRow>() {
ConnectionManager = dbConnection,
TableName = "source_customers",
Sql = "SELECT customer_id, email, name FROM source_customers WHERE change_time > @lastLoadPar",
SqlParameter = new[] {
new QueryParameter("lastLoadPar","DATETIME",lastLoadDate)
}
};
```
#### Handling Non-CDC Sources
If your source does not support CDC, you need other methods to track changes. One common approach is using a **Last Modified Timestamp**. You can compare this with the last load time to identify changes.
For example, our data might look like this when including a `last_modified` column:
| customer_id | name | email | last_modified |
|-------------|---------------|----------------------|---------------------|
| 1 | John Doe | john.doe@example.com | 2024-07-08 09:00:00 |
| 2 | Jane Smith | jane.smith@example.com| 2024-07-08 09:15:00 |
| 3 | Alice Johnson | alice.j@example.com | 2024-07-08 09:20:00 |
You can now select rows where `last_modified` is greater than the last load time to get the changes.
### Truncate Target Table
In scenarios where you want to do a full load but have a large number of changes, it may be faster to truncate the target table first and then replace it with all data from the source. This approach can significantly reduce the time and resources needed to update the table.
Here is an example using ETLBox to truncate a table and reload data:
```csharp
// Define the connection manager
var dbConnection = new SqlConnectionManager("..connection string here...");
// Truncate the target table
TruncateTableTask.Truncate(dbConnection, "customers");
// Define the data flow
var source = new CsvSource<CustomerRow>("data/customers.csv");
var cleanData = new RowTransformation<CustomerRow, CustomerRow>(row => {
// Custom data cleaning logic here
return row;
});
var destination = new DbDestination<CustomerRow>(dbConnection, "customers");
// Linking & executing the data flow
source.LinkTo(cleanData);
cleanData.LinkTo(destination);
Network.Execute(source);
```
#### Removing and Adding Indexes and Constraints
Additionally, it could be time-saving to remove any indexes / statistics / unique key constraints from the table before the insert operation, and then re-adding them after all data has been copied.
## Enhancing the DbMerge
The built-in `DbMerge` of ETLBox supports various performance scenarios out of the box.
### Using Delta with DbMerge
Both full and delta loads are supported by the DbMerge component of ETLBox. The following MergeModes are supported:
- Delta: Does inserts and updates, deletions only with a flag
- Full: Does inserts, updates, and deletions (deletions if the record is missing)
- InsertsAndUpdatesOnly: Does inserts and updates only
- UpdatesOnly: Only updates, no inserts or deletions
In the ETL code, you can adjust your data transfer class using different attributes to describe your id, update, and compare columns. For delta loads, you can also specify an attribute to indicate when a column should be deleted.
Here is an example setup of a data transfer class, that also uses the `DeleteColumn` attribute:
```csharp
public class CustomerRow
{
[ColumnMap("customer_id")]
[IdColumn]
public int CustomerId { get; set; }
[ColumnMap("name")]
[CompareColumn]
[UpdateColumn]
public string Name { get; set; }
[UpdateColumn]
[ColumnMap("email")]
public string Email { get; set; }
[DeleteColumn(true)]
public bool IsDeletion { get;set; }
}
```
### Cache Mode
By default, DbMerge will always load all data from the destination into memory first. If you want to avoid this, for example, because your target table is quite large, consider setting the CacheMode to `CacheMode.Partial`.
Setting the cache mode to partial will only load the data into memory for the currently processed batch. All other data will be removed from the cache. You can choose from different eviction policies that control how data is removed from the cache when it reaches its maximum size:
- Least Recently Used (LRU): Evicts the least recently accessed items from the cache.
- Least Frequently Used (LFU): Evicts the least frequently accessed items from the cache.
- First In First Out (FIFO): Evicts the oldest items in the cache first.
- Last In First Out (LIFO): Evicts the most recently added items first.
```csharp
DbMerge<MyMergeRow> merge = new DbMerge<MyMergeRow>(connection, "DestinationTable");
merge.CacheMode = CacheMode.Partial;
merge.EvictionPolicy = CacheEvictionPolicy.LeastRecentlyUsed;
```
### Truncating Target
Additionally, `DbMerge` has a setting `UseTruncateMethod = true`, which allows it to load the data into memory first, then truncate the table, and then insert the data while still detecting the changes. This method combines the benefits of truncating the table with the ability to track changes.
```csharp
var merge = new DbMerge<CustomerRow>(dbConnection, "customers") {
BatchSize = 2000,
UseTruncateMethod = true
};
```
In this example, `DbMerge` collects merge information and sends it to another table (`merge_info_table`). The `UseTruncateMethod` setting ensures that data is loaded into memory, the target table is truncated, and then the data is inserted, improving performance while still detecting changes.
### Delta Table
The `DbMerge` has a property `DeltaTable` which is a list containing information about what records were updated, inserted, or deleted. The operation and change date are stored in the corresponding `ChangeDate` and `ChangeAction` properties.
For example, the `merge_info_table` could have the following structure:
```sql
CREATE TABLE merge_info_table (
customer_id INT,
operation CHAR(1),
change_time DATETIME
);
```
This table will store the `customer_id` of the affected rows, the type of operation (Insert, Update, or Delete), and the timestamp of the change.
This delta table can be accessed if the `DbMerge` is not treated as a source but as a transformation. If the `DbMerge` is linked to other components, it will write the delta records into its output.
In this example, you can send the delta information further down in the data flow, for example, to another database table.
```csharp
// Define the connection manager
var dbConnection = new SqlConnectionManager("..connection string here...");
// Define the data flow
var source = new CsvSource<CustomerRow>("data/customers.csv");
var dbTypeCheck = new DbTypeCheck<CustomerRow>(dbConnection, "customers");
var merge = new DbMerge<CustomerRow>(dbConnection, "customers") {
BatchSize = 2000,
CacheMode = CacheMode.Partial,
EvictionPolicy = CacheEvictionPolicy.LeastRecentlyUsed,
MergeMode = MergeMode.Full
};
var mergeInfo = new DbDestination<MergeInfoRow>("merge_info_table", dbConnection);
// Linking
source.LinkTo(dbTypeCheck);
dbTypeCheck.LinkTo(merge);
// Collecting merge information
merge.LinkTo(mergeInfo);
// Executing the network
Network.Execute(source);
```
## Going Further: Building Dynamic Data Flows
The above examples for the `DbMerge` make use of strongly typed objects (POCOs). However, the `DbMerge` also supports the use of the dynamic `ExpandoObject`. When using the `ExpandoObject`, you don't have to create a strongly typed object beforehand. The corresponding properties are created on-the-fly whenever a value is assigned.
This feature is very powerful. Imagine you want to write integration code for hundreds of tables, perhaps even from different sources. Using the dynamic object approach lets you easily write a data flow that can handle different tables and data types without needing to define a separate POCO for each table. The target table could also be created dynamically if needed.
### Example Use Case
Consider a scenario where you need to integrate data from two different CSV files, each representing a different entity (customers and orders), but having an overlapping property (`eMail`) that should be cleaned the same way. Instead of defining a POCO for each entity, you can use `ExpandoObject` to dynamically handle the data.
```csharp
using System.Dynamic;
using ETLBox.DataFlow;
using ETLBox.Connection;
// Define the connection manager
void RunMerge(string entity) {
var dbConnection = new SqlConnectionManager("..connection string here...");
var source = new CsvSource<ExpandoObject>($"data/{entity}.csv");
// Data transformation
var cleanData = new RowTransformation<ExpandoObject, ExpandoObject>(row => {
// Data cleaning logic for both entities
dynamic dynamicRow = row;
dynamicRow.eMail = dynamicRow.eMail?.Trim().ToLower();
return dynamicRow;
});
// Define DbMerge dynamically
var merge = new DbMerge<ExpandoObject>() {
ConnectionManager = dbConnection,
TableName = entity + "s",
BatchSize = 2000,
MergeMode = MergeMode.Full
};
// Linking and executing the data flow
source.LinkTo(cleanData);
cleanData.LinkTo(merge);
Network.Execute(source);
}
```
You could further enhance the dynamic nature of your data flow by creating target tables on the fly based on the schema of the incoming data. This can be particularly useful in scenarios where the schema is not known beforehand. An introduction to creating dynamic data flows like this will be part of another article.
## Conclusion

Often, people think that linear regression models cannot capture these complexities. However, with a few adjustments, linear regressions can be surprisingly effective in modeling non-linear relationships. In this article, we will explore how to adapt a linear regression model for non-linear phenomena using Python and NumPy.
**Linear Regression Model**
Linear regression seeks to find the best line (or hyperplane in higher dimensions) that minimizes the error between predictions and actual values. The equation of a simple linear regression model is:
For multivariate models, this equation becomes:
**Transforming Variables to Capture Non-Linearity**
To adapt this model to non-linear phenomena, we can transform the input variables using non-linear functions. For example, we can include quadratic or cubic terms:
These transformations allow the linear model to learn complex non-linear relationships.
**Cost Function**
The cost function for linear regression is usually the mean squared error (MSE):
**Gradient Descent**
To minimize the cost function, we use the gradient descent algorithm. The parameter updates are as follows:
where **𝛼** is the learning rate.
**Implementation in Python with NumPy**
Here is a simple implementation in Python:
```
import numpy as np
from sklearn.datasets import make_regression
import matplotlib.pyplot as plt
```
```
x, y = make_regression(n_samples=100, n_features=1, noise=10)
y = y + abs(y/2)
plt.scatter(x, y)
```
```
X = np.hstack((x, np.ones(x.shape)))
X = np.hstack((x**2, X))
```
```
theta = np.random.randn(3, 1)
theta
```
```
def cost_function(X, y, theta):
m = len(y)
return 1/(2*m) * np.sum((model(X, theta) - y)**2)
```
```
def grad(X, y, theta):
m = len(y)
return 1/m * X.T.dot(model(X, theta) - y)
def gradient_descent(X, y, theta, learning_rate, n_iter):
cost_history = np.zeros(n_iter)
for i in range(0, n_iter):
theta = theta - learning_rate * grad(X, y, theta)
cost_history[i] = cost_function(X, y, theta)
return theta, cost_history
```
```
n_iter = 1000
learning_rate = 0.01
theta_final, cost_history = gradient_descent(X, y, theta, learning_rate, n_iter)
predict = model(X, theta_final)
plt.scatter(x[:, 0], y)
plt.scatter(x[:, 0], predict, c='r')
```
By transforming the input variables, we can use linear regression models to capture non-linear relationships. This flexibility, combined with techniques such as gradient descent, allows linear models to handle much more complex phenomena than they would normally. NumPy provides a solid foundation for implementing these concepts in Python, making non-linear modeling more accessible. | moubarakmohame4 |

## How to Build an API with Laravel Breeze in Laravel 11
A step-by-step guide on building a simple API with authentication using Laravel Breeze in Laravel 11.
### Step 1: Install Laravel
First, create a new Laravel project using the Laravel installer or Composer.
```bash
laravel new api-breeze
# Or via Composer
composer create-project laravel/laravel api-breeze
cd api-breeze
```
### Step 2: Install Laravel Breeze
Next, install Laravel Breeze and its dependencies.
```bash
composer require laravel/breeze --dev
php artisan breeze:install api
```
This command will install Breeze and set up the necessary scaffolding for API authentication.
### Step 3: Configure the Database and Run Migrations
1. Update your .env file with your database credentials:
```bash
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel11_api
DB_USERNAME=root
DB_PASSWORD=
```
2. Run the migrations to set up your database tables:
```bash
php artisan migrate
```
### Step 4: Create Authentication Endpoints
Laravel Breeze provides the necessary endpoints for registration, login, and logout. The routes are defined in routes/api.php.
```bash
use App\Http\Controllers\Auth\AuthenticatedSessionController;
use App\Http\Controllers\Auth\RegisteredUserController;
use Illuminate\Support\Facades\Route;
Route::post('/register', [RegisteredUserController::class, 'store']);
Route::post('/login', [AuthenticatedSessionController::class, 'store']);
Route::post('/logout', [AuthenticatedSessionController::class, 'destroy'])->middleware('auth:sanctum');
```
### Step 5: Update Controllers
Modify the `RegisteredUserController` and `AuthenticatedSessionController` to return JSON responses.
`RegisteredUserController.php`
```bash
namespace App\Http\Controllers\Auth;
use App\Models\User;
use Illuminate\Auth\Events\Registered;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Hash;
use Illuminate\Validation\Rules;
use App\Http\Controllers\Controller;
class RegisteredUserController extends Controller
{
public function store(Request $request)
{
$request->validate([
'name' => ['required', 'string', 'max:255'],
'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
'password' => ['required', 'confirmed', Rules\Password::defaults()],
]);
$user = User::create([
'name' => $request->name,
'email' => $request->email,
'password' => Hash::make($request->password),
]);
event(new Registered($user));
$token = $user->createToken('auth_token')->plainTextToken;
return response()->json([
'access_token' => $token,
'token_type' => 'Bearer',
'user' => $user
]);
}
}
```
`AuthenticatedSessionController.php`
```bash
namespace App\Http\Controllers\Auth;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use App\Http\Controllers\Controller;
class AuthenticatedSessionController extends Controller
{
public function store(Request $request)
{
$request->validate([
'email' => ['required', 'string', 'email'],
'password' => ['required', 'string'],
]);
if (!Auth::attempt($request->only('email', 'password'))) {
return response()->json(['message' => 'Invalid login credentials'], 401);
}
$user = Auth::user();
$token = $user->createToken('auth_token')->plainTextToken;
return response()->json([
'access_token' => $token,
'token_type' => 'Bearer',
'user' => $user,
'status' => 'Login successful',
]);
}
public function destroy(Request $request)
{
$request->user()->currentAccessToken()->delete();
return response()->json(['message' => 'Logout successful']);
}
}
```
### Step 5: Run Laravel App
```bash
php artisan serve
```
### Step 6: Check following API
Test Your API with Thunder Client

1,921,301 | LeetCode Meditations: Longest Palindromic Substring | Let's start with the description for Longest Palindromic Substring: Given a string s, return the... | 26,418 | 2024-07-12T15:10:54 | https://rivea0.github.io/blog/leetcode-meditations-longest-palindromic-substring | computerscience, algorithms, typescript, javascript | Let's start with the description for [Longest Palindromic Substring](https://leetcode.com/problems/longest-palindromic-substring):
> Given a string `s`, return _the longest palindromic substring_ in `s`.
For example:
```
Input: s = "babad"
Output: "bab"
Explanation: "aba" is also a valid answer.
```
Or:
```
Input: s = "cbbd"
Output: "bb"
```
Also, the constraints indicate that *`s` consists of only digits and English letters.*
---
In this series, we've checked before [if a string is a palindrome](https://rivea0.github.io/blog/leetcode-meditations-valid-palindrome) using the [two pointers](https://rivea0.github.io/blog/leetcode-meditations-chapter-2-two-pointers) approach.
With two pointers, *checking if a string is a palindrome* is not too hard: we can initialize a `left` pointer that starts off from the left and a `right` pointer that starts off from the right. While they're pointing at the same character, we can keep updating them, going until the middle character in the string. If at some point they differ, the string itself is not a palindrome, so we return `false`.
But, our aim in this problem is **not** to check for the validity of a palindromic string, it's entirely different. We need to get the result of the longest possible palindrome in the string — which doesn't have to be a palindrome itself.
---
We can start with initializing a `maxLength` variable with the value `1` (remember that our constraints say that the minimum length of `s` is `1`):
```ts
let maxLength = 1;
```
Then, we can initialize our starting index, which will slice our string from the starting point of the maximum length palindrome:
```ts
let start = 0;
```
So that at the end we can return that "window":
```ts
function longestPalindrome(s: string): string {
/* ... */
return s.slice(start, start + maxLength);
}
```
To find a palindrome in the string, we can use an "expand over center" approach. For each character, we'll assume that it is the middle character and expand our two pointers `left` and `right` accordingly.
We'll first start with getting the `right` pointer to the right place: the first position that it differs from the current character:
```ts
for (let i = 0; i < s.length; i++) {
let right = i;
while (right < s.length && s[i] === s[right]) {
right++;
}
/* ... */
}
```
Then, we'll initialize our `left` pointer to point on the left side of our current character:
```ts
for (let i = 0; i < s.length; i++) {
/* ... */
let left = i - 1;
}
```
After that, while we're within bounds and still looking at a palindrome, we can continue expanding:
```ts
for (let i = 0; i < s.length; i++) {
/* ... */
while (left >= 0 && right < s.length && s[left] === s[right]) {
left--;
right++;
}
}
```
However, the crucial part is that we need to update the maximum length if we find a longer palindrome:
```ts
for (let i = 0; i < s.length; i++) {
/* ... */
let currentLength = right - left - 1;
if (currentLength > maxLength) {
maxLength = currentLength;
start = left + 1;
}
}
```
And, that's it for the whole function. Here's how it looks like:
```ts
function longestPalindrome(s: string): string {
let maxLength = 1; // Constraint: 1 <= s.length <= 1000
let start = 0;
for (let i = 0; i < s.length; i++) {
let right = i;
while (right < s.length && s[i] === s[right]) {
right++;
}
let left = i - 1;
while (left >= 0 && right < s.length && s[left] === s[right]) {
left--;
right++;
}
let currentLength = right - left - 1;
if (currentLength > maxLength) {
maxLength = currentLength;
start = left + 1;
}
}
return s.slice(start, start + maxLength);
}
```
#### Time and space complexity
The time complexity for this solution is {% katex inline %} O(n^2) {% endkatex %} as in the worst case we'll be iterating over the whole string for each character. The space complexity is {% katex inline %} O(1) {% endkatex %} because we don't require additional storage that will grow proportionately to the input size.

Next up is another problem related to palindromes: [Palindromic Substrings](https://leetcode.com/problems/palindromic-substrings). Until then, happy coding.

1,921,305 | Leveraging Zod for Form Validation in React: Unleashing the Power of superRefine | Introduction: The Quest for Perfect Form Validation Meet Lisa, a seasoned developer at... | 0 | 2024-07-12T15:12:29 | https://dev.to/gleidsonleite/leveraging-zod-for-form-validation-in-react-unleashing-the-power-of-superrefine-170j | react, typescript, frontend, node | ## Introduction: The Quest for Perfect Form Validation
Meet Lisa, a seasoned developer at EventPro, a company that creates software for managing events. One day, her manager approaches her with a new challenge: to build a sophisticated user registration form for their latest event management application. This form isn’t just a simple set of fields; it has complex validation rules that vary based on the user's input.
For instance, if the user is a VIP, additional fields like VIP code and extra information must be validated. However, handling such conditional logic within the form’s validation can quickly become a tangled mess, making the code hard to read and maintain. Lisa realizes that she needs a better way to handle these complex validation rules.
## The Challenge: Validating Complex Forms
Lisa has encountered similar challenges before. Traditionally, she would use a combination of state management and conditional rendering to enforce validation rules. This often required creating multiple versions of the form schema, using hooks like **useMemo** to dynamically generate the schema based on user input. It was cumbersome, error-prone, and made the codebase difficult to maintain.
This time, Lisa decides to use Zod, a TypeScript-first schema declaration and validation library, which promises to simplify her task. She discovers that Zod’s powerful **superRefine** method can handle complex validation logic efficiently.
## Seeting Up the Project
Lisa sets up a new React project and installs Zod:
``` bash
npx create-react-app eventpro-registration
cd eventpro-registration
npm install zod
```
## Creating the Form Schema with Zod
Lisa defines a Zod schema to validate the form data. The schema uses **superRefine** to handle complex validation logic that depends on multiple fields.
```typescript
import { z } from 'zod';
const isValidPhoneNumber = (number: string) => {
return /^\d{10}$/.test(number);
};
export const registrationSchema = z
.object({
name: z.string().min(1, { message: 'Name is required' }),
email: z.string().email({ message: 'Invalid email address' }),
phoneNumber: z.string().refine(isValidPhoneNumber, {
message: 'Invalid phone number',
}),
isVIP: z.boolean(),
vipCode: z.string().optional(),
additionalInfo: z.string().optional(),
})
.superRefine((data, ctx) => {
if (data.isVIP) {
if (!data.vipCode) {
ctx.addIssue({
path: ['vipCode'],
code: z.ZodIssueCode.custom,
message: 'VIP Code is required for VIPs',
});
}
if (data.vipCode && data.vipCode.length !== 8) {
ctx.addIssue({
path: ['vipCode'],
code: z.ZodIssueCode.custom,
message: 'VIP Code must be exactly 8 characters long',
});
}
if (!data.additionalInfo) {
ctx.addIssue({
path: ['additionalInfo'],
code: z.ZodIssueCode.custom,
message: 'Additional information is required for VIPs',
});
}
}
});
```
## Integrating the Schema with React
With the schema ready, Lisa integrates it with her React form using a custom hook for validation.
```typescript
import React, { useState } from 'react';
import { useForm } from 'react-hook-form';
import { zodResolver } from '@hookform/resolvers/zod';
import { registrationSchema } from './validationSchema';
const RegistrationForm: React.FC = () => {
const {
register,
handleSubmit,
formState: { errors },
} = useForm({
resolver: zodResolver(registrationSchema),
});
const onSubmit = (data: any) => {
console.log('Form Submitted', data);
};
return (
<form onSubmit={handleSubmit(onSubmit)}>
<div>
<label>Name:</label>
<input {...register('name')} />
{errors.name && <p>{errors.name.message}</p>}
</div>
<div>
<label>Email:</label>
<input {...register('email')} />
{errors.email && <p>{errors.email.message}</p>}
</div>
<div>
<label>Phone Number:</label>
<input {...register('phoneNumber')} />
{errors.phoneNumber && <p>{errors.phoneNumber.message}</p>}
</div>
<div>
<label>
<input type="checkbox" {...register('isVIP')} />
VIP
</label>
</div>
{errors.isVIP && <p>{errors.isVIP.message}</p>}
<div>
<label>VIP Code:</label>
<input {...register('vipCode')} />
{errors.vipCode && <p>{errors.vipCode.message}</p>}
</div>
<div>
<label>Additional Information:</label>
<textarea {...register('additionalInfo')} />
{errors.additionalInfo && <p>{errors.additionalInfo.message}</p>}
</div>
<button type="submit">Register</button>
</form>
);
};
export default RegistrationForm;
```
## The Power of **superRefine**
with **superRefine**, Lisa can ensure that
* The VIP code is required and exactly 8 characters long for VIP users.
* Additional information is mandatory for VIP users.
* The validation logic remains clean and centralized within the schema, making it easier to maintain and understand.
## The Key Benefit: Eliminating Conditional Schema Logic
Previously, developers might have had to use complex conditional logic or dynamically generate new schemas with hooks like **useMemo** to handle scenarios where certain fields become required based on user input. This approach could be cumbersome and error-prone.
With Zod’s **superRefine**, Lisa avoids the need to generate new schemas dynamically. Instead, she can include all the necessary conditional validation logic directly within the schema. This approach simplifies the code and reduces the likelihood of bugs.
## Benefits of Using Zod with **superRefine**
1. Centralized Validation Logic: Keeping validation logic within the schema makes the code cleaner and easier to maintain.
2. Complex Validation Made Simple: superRefine allows for complex validation rules that depend on multiple fields.
3. Improved Developer Experience: By using TypeScript, Zod provides better type safety and editor support, reducing bugs and improving productivity.
## Conclusion: Elevating Form Validation
By leveraging Zod and its **superRefine** method, Lisa was able to create a robust and flexible form validation system for EventPro's registration form. This approach not only made the code more maintainable but also improved the overall development experience. As a developer, adopting tools like Zod can significantly enhance your ability to handle complex validation scenarios with ease.
Happy coding, and may your forms always validate flawlessly! | gleidsonleite |

As aspiring software engineers, you're embarking on a journey to master complex technical skills. However, the path to true expertise might surprise you. While books, courses, and tutorials provide valuable knowledge, they're just the beginning. To truly excel, you must embrace a counterintuitive truth: learning by doing, making mistakes, and reflecting on those experiences is the key to rapid skill development.
**The Trap of Passive Learning**
It's tempting to believe that consuming more information – watching endless YouTube tutorials, enrolling in course after course, or devouring technical books – will magically transform you into a skilled developer. While these resources have their place, relying solely on them creates a false sense of progress. You might feel like you're learning, but without practical application, that knowledge remains theoretical.
**The Power of Getting Your Hands Dirty**
True mastery comes from diving in and writing code, even when you're unsure. Here's why this approach is so effective:
**1. Bridging the Theory-Practice Gap**: Concepts that seem clear in tutorials often become surprisingly challenging when you try to implement them. This struggle is where real learning occurs.
**2. Developing Problem-Solving Skills**: When you encounter roadblocks (and you will), you're forced to think critically, research solutions, and develop the problem-solving mindset crucial for software engineering.
**3. Building Confidence**: Each obstacle you overcome, no matter how small, builds your confidence and resilience. This psychological aspect is vital for long-term success.
**4. Internalizing Concepts**: Actively working with code helps you internalize programming patterns and best practices far more effectively than passive learning.
**Embracing Failure as a Learning Tool**
**Here's a liberating truth: it's not only okay to make mistakes – it's essential. Here's why:**
**1. Fail Fast, Learn Fast**: The sooner you make mistakes, the quicker you can identify and correct them. This accelerates your learning curve dramatically.
**2. Deep Understanding**: Debugging your own errors leads to a much deeper understanding of how things work than simply following along with tutorials.
**3. Memory Reinforcement**: The frustration of a bug and the satisfaction of fixing it create strong mental connections, helping you remember solutions for future projects.
**4. Developing Grit**: Software development often involves tackling complex, unclear problems. Embracing early failures builds the resilience needed to persevere through challenges.
**The Iterative Learning Cycle**
Adopt this powerful approach to skill development:
**1. Learn the Basics**: Gain a foundational understanding through courses or documentation.
**2. Apply Immediately**: Start a project, even if you feel underprepared.
**3. Encounter Obstacles**: You'll inevitably get stuck or make mistakes. This is good!
**4. Research and Solve**: Use resources to overcome these hurdles.
**5. Reflect**: Analyze what you learned from the process.
**6. Repeat**: Take on progressively more challenging projects.
**Practical Tips for Effective Learning**
**1. Start Small**: Begin with manageable projects that stretch your skills slightly.
**2. Set Clear Goals**: Define what you want to achieve with each project.
**3. Time-Box Your Efforts**: Avoid endless information gathering. Set a time limit, then start coding.
**4. Embrace the Struggle**: When you're stuck, resist the urge to immediately watch a tutorial. Try to solve it yourself first.
**5. Join a Community**: Connect with other learners for support and knowledge sharing.
**6. Code Review**: If possible, have experienced developers review your code and provide feedback.
**Conclusion**
Remember, every experienced software engineer started exactly where you are now. They didn't achieve mastery through perfect code written on the first try. Instead, they embraced the messy, sometimes frustrating process of learning by doing.
So, **close** that tutorial video, step away from the endless stream of courses, and start that project you've been hesitating to begin. Yes, you'll make mistakes. Yes, you'll get stuck. But with each hurdle you overcome, you'll be building real, practical skills that no amount of passive learning can provide.
