1,926,167 | The Ultimate Guide to Custom Theming with React Native Paper, Expo and Expo Router | React Native Paper is an excellent and user-friendly UI library for React Native, especially for... | 0 | 2024-07-17T04:29:40 | https://dev.to/hemanshum/the-ultimate-guide-to-custom-theming-with-react-native-paper-expo-and-expo-router-3hjl | reactnative, exporouter, beginners, tutorial | React Native Paper is an excellent and user-friendly UI library for React Native, especially for customizing dark and light themes with its [Dynamic Theme Colors Tool](https://callstack.github.io/react-native-paper/docs/guides/theming/#creating-dynamic-theme-colors). However, configuring it with Expo and Expo Router can be tricky. Additionally, creating a toggle button for theme switching without a central state management system can be challenging. Expo Router can help with this.
In this article, we will learn how to:
- Create custom light and dark themes.
- Configure these themes for use with React Native Paper, Expo and Expo Router.
- Implement a toggle button to switch between light and dark modes within the app.
If you like to watch this tutorial you can check out the video tutorial here: {% embed https://youtu.be/JkepeUIrwUs %}
**Setup a Expo Project**
Open your terminal and type:
`npx create-expo-app@latest`
It will ask for a project name, in my case I gave “rnpPractice”.
After Installation go into project directory and open your code editor in it and run.
Now it’s install React Native Paper and required dependency packages in the project folder.
`npm install react-native-paper react-native-safe-area-context`
Open babel.config.js in you code editor and change the following code:
```
module.exports = function(api) {
api.cache(true);
return {
presets: ['babel-preset-expo'],
//ADD CODE START
env: {
production: {
plugins: ['react-native-paper/babel'],
},
},
//ADD CODE END
};
};
```
Let’s reset the project so we can remove the unnecessary files, run the following to reset our project:
`npm run reset-project`
We will create a new folder in the root of our project called ‘ src ’ and move following folders in it:
- app
- components
- constants
- hooks
It will look the following screenshot:
Now in app folder let’s create a folder name (tabs), you must create a folder with parenthesis around the word tabs, that how we can create a bottom tab navigation in Expo Router. We will move our index.js file from app (the parent folder) to (tabs) (the child folder) and now create two more files in the (tabs) folder. one is “_layout.js” and 2nd settings.js. Now you app folder should look like the following screenshot:
Let’s fill settings.js with some boiler plate code:
```
import { StyleSheet, View, Text } from "react-native";
const Settings = () => {
return (
<View>
<Text>Settings</Text>
</View>
);
};
const styles = StyleSheet.create({});
export default Settings;
```
Now for Expo router to work properly we need to update the “_layout.js” files in app and (tabs) folder:
Update _layout.js in app folder with following code:
```
import {Stack} from 'expo-router';
export default function RootLayout() {
return (
<Stack>
<Stack.Screen
name="(tabs)"
options={{
headerShown: false,
}}
/>
</Stack>
)
}
```
and in (tabs) folder _layout.js file:
```
import { Tabs } from "expo-router";
import { Feather } from "@expo/vector-icons";
export default function TabLayout() {
return (
<Tabs>
<Tabs.Screen
name="index"
options={{
title: "Home",
tabBarIcon: ({ color }) => (
<Feather name="home" size={24} color={color} />
),
}}
/>
<Tabs.Screen
name="settings"
options={{
title: "Setting",
tabBarIcon: ({ color }) => (
<Feather name="settings" size={24} color={color} />
),
}}
/>
</Tabs>
);
}
```
Now let’s run the app and see everything is running ok.
`npm run start`
Now your project will start, you can run your project on emulator or simulator or on you phone by scanning the QR code and install Expo Go App on your phone.
**Create and Configure the React Native Paper Theme**
Let’s create our custom dark & light theme first, for that [follow the link](https://callstack.github.io/react-native-paper/docs/guides/theming/#creating-dynamic-theme-colors). Here you just have to select the colors Primary, Secondary and Tertiary and it will create you a light and dark theme.
Now rename your Colors.ts file to Colors.js if you are using JavaScript and not TypeScript, then open that file. Copy the light theme colors object from website and paste it in light colors object in Colors.js file and do same for the Dark theme and your file will look likes this:
```
export const Colors = {
light: {
primary: "rgb(176, 46, 0)",
onPrimary: "rgb(255, 255, 255)",
primaryContainer: "rgb(255, 219, 209)",
onPrimaryContainer: "rgb(59, 9, 0)",
secondary: "rgb(0, 99, 154)",
onSecondary: "rgb(255, 255, 255)",

onSurfaceDisabled: "rgba(32, 26, 24, 0.38)",
backdrop: "rgba(59, 45, 41, 0.4)",
},
dark: {

onSurfaceVariant: "rgb(216, 194, 188)",
outline: "rgb(160, 140, 135)",
outlineVariant: "rgb(83, 67, 63)",
shadow: "rgb(0, 0, 0)",
scrim: "rgb(0, 0, 0)",
inverseSurface: "rgb(237, 224, 221)",
inverseOnSurface: "rgb(54, 47, 45)",
inversePrimary: "rgb(176, 46, 0)",
elevation: {
level0: "transparent",
level1: "rgb(43, 34, 31)",
level2: "rgb(50, 38, 35)",
level3: "rgb(57, 43, 39)",
level4: "rgb(59, 45, 40)",
level5: "rgb(63, 48, 43)",
},
surfaceDisabled: "rgba(237, 224, 221, 0.12)",
onSurfaceDisabled: "rgba(237, 224, 221, 0.38)",
backdrop: "rgba(59, 45, 41, 0.4)",
},
};
```
Now let’s use our theme, for that open the _layout.js file in app folder and import:
```
import {Stack} from 'expo-router';
//Import the code Start
import {
MD3DarkTheme,
MD3LightTheme,
PaperProvider,
} from "react-native-paper";
//Import the code End
export default function RootLayout() {
return (
<Stack>
<Stack.Screen
name="(tabs)"
options={{
headerShown: false,
}}
/>
</Stack>
)
}
```
Now let’s wrap our code in <PaperProvider> in _layout.js file in app folder like the following:
```
import {Stack} from 'expo-router';
import {
MD3DarkTheme,
MD3LightTheme,
PaperProvider,
} from "react-native-paper";
export default function RootLayout() {
return (
<PaperProvider> //Start there
<Stack>
<Stack.Screen
name="(tabs)"
options={{
headerShown: false,
}}
/>
</Stack>
</PaperProvider> //End here
)
}
```
👆 This will allow us to use React Native Paper components in our app.
Now to apply our color theme we need to import Colors from the Colors.js file and merge it on the colors object in the current theme in React Native Paper. Confusing? 🤔
Let write the code to understand 😁. Open _layout.js file in app folder:
```
import {Stack} from 'expo-router';
import {
MD3DarkTheme,
MD3LightTheme,
PaperProvider,
} from "react-native-paper";
//1. Import Our Colors
import { Colors } from "../constants/Colors";
//2. Overwrite it on the current theme
const customDarkTheme = { ...MD3DarkTheme, colors: Colors.dark };
const customLightTheme = { ...MD3LightTheme, colors: Colors.light };
export default function RootLayout() {
return (
// 3.Use any theme you like for your app
<PaperProvider theme={customDarkTheme}>
<Stack>
<Stack.Screen
name="(tabs)"
options={{
headerShown: false,
}}
/>
</Stack>
</PaperProvider>
)
}
```
Let’s make our app decide which theme to use as per the users device. For that we are going to use a Hook provided by React Native called useColorScheme. The useColorScheme React hook provides and subscribes to color scheme preferred by the user’s device. [Read More.](https://reactnative.dev/docs/usecolorscheme)
Open _layout.js file in app folder:
```
import { Stack } from 'expo-router';
//1. Import the useColorScheme hook
import { useColorScheme } from 'react-native';
import {
MD3DarkTheme,
MD3LightTheme,
PaperProvider,
} from "react-native-paper";
import { Colors } from "../constants/Colors";
const customDarkTheme = { ...MD3DarkTheme, colors: Colors.dark };
const customLightTheme = { ...MD3LightTheme, colors: Colors.light };
export default function RootLayout() {
//2. Get the value in a const
const colorScheme = useColorScheme();
//3. Let's decide which theme to use
const paperTheme =
colorScheme === "dark" ? customDarkTheme : customLightTheme;
return (
//4. apply the theme
<PaperProvider theme={paperTheme}>
<Stack>
<Stack.Screen
name="(tabs)"
options={{
headerShown: false,
}}
/>
</Stack>
</PaperProvider>
)
}
```
Now it’s time to test, let’s go into (tabs) folder and open index.js and copy following code:
```
import { View } from "react-native";
import { Avatar, Button, Card, Text } from "react-native-paper";
const LeftContent = (props) => <Avatar.Icon {...props} icon="folder" />;
export default function Index() {
return (
<View
style={{
flex: 1,
margin: 16,
}}
>
<Card>
<Card.Cover source={{ uri: "https://picsum.photos/700" }} />
<Card.Title
title="Card Title"
subtitle="Card Subtitle"
left={LeftContent}
/>
<Card.Content>
<Text variant="bodyMedium">
Lorem ipsum dolor sit amet consectetur adipisicing elit. Quisquam
tenetur odit eveniet inventore magnam officia quia nemo porro?
Dolore sapiente quos illo distinctio nisi incidunt? Eaque officiis
iusto exercitationem natus?
</Text>
</Card.Content>
<Card.Actions>
<Button>Open</Button>
</Card.Actions>
</Card>
</View>
);
}
```
You can see that your theme is applied but only on the card you imported from React Native Paper, your navigation is still using a default theme provided by Expo Router.
Now let’s merge the Expo Router theme in React Native Paper theme and use the same theme for both. To achieve that let’s get back to _layout.js file in app folder and make the following changes:
```
import { Stack } from 'expo-router';
import { useColorScheme } from 'react-native';
import {
MD3DarkTheme,
MD3LightTheme,
PaperProvider,
adaptNavigationTheme, //1. Import this package
} from "react-native-paper";
//2. Import Router Theme
import {
DarkTheme as NavigationDarkTheme,
DefaultTheme as NavigationDefaultTheme,
ThemeProvider,
} from "@react-navigation/native";
//3. Install deepmerge first and import it
import merge from "deepmerge";
import { Colors } from "../constants/Colors";
const customDarkTheme = { ...MD3DarkTheme, colors: Colors.dark };
const customLightTheme = { ...MD3LightTheme, colors: Colors.light };
//4. The adaptNavigationTheme function takes an existing React Navigation
// theme and returns a React Navigation theme using the colors from
// Material Design 3.
const { LightTheme, DarkTheme } = adaptNavigationTheme({
reactNavigationLight: NavigationDefaultTheme,
reactNavigationDark: NavigationDarkTheme,
});
//5.We will merge React Native Paper Theme and Expo Router Theme
// using deepmerge
const CombinedLightTheme = merge(LightTheme, customLightTheme);
const CombinedDarkTheme = merge(DarkTheme, customDarkTheme);
export default function RootLayout() {
const colorScheme = useColorScheme();
//6. Let's use the merged themes
const paperTheme =
colorScheme === "dark" ? CombinedDarkTheme : CombinedLightTheme;
return (
<PaperProvider theme={paperTheme}>
//7.We need to use theme provider from react navigation
//to apply our theme on Navigation components
<ThemeProvider value={paperTheme}>
<Stack>
<Stack.Screen
name="(tabs)"
options={{
headerShown: false,
}}
/>
</Stack>
</ThemeProvider>
</PaperProvider>
)
}
```
That's it guys this should apply our theme to both React Native Paper Components and Navigation Components like Header Navigation or Bottom Tag Navigation.

**Wrapping Up**
We’ve covered a lot of ground in this blog post, from creating custom light and dark themes to configuring them for use with React Native Paper, Expo and Expo Router. By now, you should have a solid foundation for implementing theming in your Expo projects. For those looking to add a toggle button to switch between these themes within your app, I’ve created a detailed video tutorial. Check out the video, with a convenient timestamp for the relevant section, here: [Video Tutorial.](https://youtu.be/JkepeUIrwUs)
Happy coding, and may your apps always look great — in light and in dark! 🌓✨

1,926,169 | Unlocking the Power of C++: A Fun Journey into Game Development | Unlocking the Power of C++: A Fun Journey into Game Development ... | 0 | 2024-07-17T04:07:17 | https://dev.to/isamarsoftwareengineer/unlocking-the-power-of-c-a-fun-journey-into-game-development-2d6f | cpp, c, gamedev |
## Unlocking the Power of C++: A Fun Journey into Game Development
## Introduction
C++ is a programming language that has stood the test of time. Known for its performance and efficiency, C++ is a favorite among game developers. Whether you're a beginner or a seasoned programmer, learning C++ can open up a world of possibilities in game development. This blog will take you through the journey of learning C++ and the thrill of using it to create gaming applications.
## Why Learn C++?
### 1. Performance and Efficiency
C++ is known for its high performance and efficiency. Unlike some other programming languages, C++ gives you control over system resources, memory management, and hardware interaction. This control is crucial in game development, where performance can make or break the gaming experience.
### 2. Industry Standard
C++ is widely used in the gaming industry. Major game engines like Unreal Engine are built using C++. Learning C++ equips you with skills that are in high demand in the game development industry.
### 3. Versatility
C++ is versatile and can be used for developing a wide range of applications. From system software to game engines, C++'s versatility makes it an invaluable tool in a programmer's toolkit.
## Getting Started with C++
### 1. Setting Up Your Environment
Before you can start coding in C++, you need to set up your development environment. For macOS users, you can use Xcode or other text editors like Visual Studio Code or Sublime Text. For Windows users, Visual Studio is a popular choice.
### 2. Writing Your First Program
Start with a simple "Hello, World!" program. This basic program will give you a feel for the syntax and structure of C++.
```cpp
#include <iostream>
int main() {
std::cout << "Hello, World!" << std::endl;
return 0;
}
```
Compile and run your program to see the output.
### 3. Understanding the Basics
Learn the fundamental concepts of C++ such as variables, data types, control structures, functions, and object-oriented programming. These basics are the building blocks for more complex programs.
## **The Fun Part: Game Development**
##1. Creating Simple Games
Start with simple games like Tic-Tac-Toe or a text-based adventure game. These projects will help you apply the basics of C++ in a fun and engaging way.
##2. Exploring Game Engines
Once you're comfortable with the basics, dive into game engines like Unreal Engine or Unity (which supports C++ scripting). These engines provide powerful tools and libraries that simplify the game development process.
### 3. Building Your Own Game
Challenge yourself by building your own game from scratch. This project will push your C++ skills to the limit and give you a sense of accomplishment.
### 4. Optimizing for Performance
One of the most exciting aspects of using C++ in game development is optimizing your game for performance. Fine-tuning your code to run efficiently on different hardware can be incredibly satisfying.
## **The Joy of Creating**
### 1. Seeing Your Ideas Come to Life
There's nothing quite like seeing your ideas come to life in the form of a game. The process of designing, coding, and testing your game can be a deeply rewarding experience.
### 2. Sharing with Others
Share your games with friends, family, or the gaming community. Getting feedback and seeing others enjoy your creation can be incredibly motivating.
### 3. Continuous Learning
Game development with C++ is a continuous learning journey. There's always something new to learn, whether it's a new algorithm, a design pattern, or a cutting-edge graphics technique.
## Conclusion
Learning C++ and using it for game development can be a fun and rewarding experience. The combination of C++'s performance, control, and industry relevance makes it an excellent choice for aspiring game developers. So, dive in, start coding, and unlock the power of C++ in your gaming projects. | isamarsoftwareengineer |

This tool is for you... | Consider this scenario, you are working on a project with your team and you use docker for... | 0 | 2024-07-17T16:52:19 | https://dev.to/ajaydsan/sick-of-managing-docker-objects-this-tool-is-for-you-1ffe | docker, programming, devops, go | Consider this scenario, you are working on a project with your team and you use docker for containerization for easy collaboration, great. You are focused, working at peak efficiency, and are in THE ZONE. Now, you realize you have stop the current container (for whatever reason), but it is not that straightforward...you first do `docker ps` and DRAG YOUR MOUSE across the screen to select and copy the ID of the container, and then you do `docker container stop {ID}` to stop the container. And then when you think you have accomplished your goal you realize you copied the wrong ID and stopped the wrong container.
There is a decent chance you've previously had this kind of experience, at least once. And if you are like me, you do not want to spin up a whole browser (psst..electron) and drag your mouse across the screen to manage your docker objects inefficiently (i.e. docker desktop).
My point is `docker cli`, though great, is annoying to use repeatedly. And god forbid if you do not use docker enough, you drop everything and check docker docs on how to delete a container (I'm guilty of this), this takes you out of your workflow and introduces more distraction. There has to be a better way to do this. That's when I decided to write this TUI in Golang and it's named `goManageDocker` (get it ?🤭)
TLDR:
gmd is a TUI tool that lets you manage your docker objects quickly and efficiently using sensible keybindings. It has VIM keybinds as well (for all you VIM nerds).
I know what you are thinking, "This is so cool, just give me the repo link already!!". [This is it](https://github.com/ajayd-san/gomanagedocker)
This post aims to give a brief tour of the tool.
## Navigation
As I mentioned before this tool focuses on efficiency and speed ( and nothing can be faster than VIM, ofc 🙄), so you have VIM keybinds at your disposal for MAX SPEED!
## Easy object management:
With this tool, you can easily delete, prune, start, and stop with a single keystroke.
I'll demonstrate the container delete function:
You can also, press `D` to force delete (this would not show the prompt).
## Cleanest way to exec into a container:
Instead of typing two different commands to exec, this is a cooler way to exec:
Just press `x` on the container you want!!
You can also exec directly from images (this starts a container and then execs into it).
## Blazing fast fuzzy search:
I know this isn't rust 🦀, but regardless this is a BLAZING FAST way to search for an object. Just press `/` and search away!
## Let gmd scout for you
If you like performing `docker scout quickview`, `gmd` has your back. Just press `s` on an image and you'll see a neatly formatted table.
Isn't this cool!?
And this marks the end of my post. There are a lot of things that I haven't shown because I want to keep this brief. But, if this interests you, you can check out the project at [here](https://github.com/ajayd-san/gomanagedocker). There is pretty detailed readme, so you'll find everything over there (including config options).
I'm considering adding more features to this project in the future. If you have any suggestions, be sure to open a new issue and contributions to existing issues are welcome!
Feel free to post your queries in comments.
Thanks for reading so far!
You have a great day ahead 😸! | ajaydsan |

1,926,174 | You can now Animate `height: auto` in CSS Without JavaScript!🚀 | Introduction Animating height: auto in CSS has been a long-standing challenge for web... | 0 | 2024-07-17T04:15:50 | https://dev.to/srijan_karki/you-can-now-animate-height-auto-in-css-without-javascript-4o20 | webdev, beginners, css, animation | ### Introduction
Animating `height: auto` in CSS has been a long-standing challenge for web developers. Traditionally, CSS requires a specific height value to animate, making it impossible to transition to/from `height: auto` directly. This limitation forced developers to resort to JavaScript for calculating and animating element heights. But now, CSS introduces the game-changing `calc-size()` function, making these animations not only possible but also straightforward.
### The Magic of `calc-size()`
The `calc-size()` function operates similarly to the `calc()` function but extends its capabilities to handle automatically calculated sizes by the browser, including:
- `auto`
- `min-content`
- `max-content`
- `fit-content`
- `stretch`
- `contain`
Essentially, `calc-size()` converts values like `auto` into specific pixel values, which can then be used in calculations with other values. This is particularly useful for animating elements with dynamic sizes.
#### Basic Usage
Consider this simple example:
```css
.element {
height: 0;
overflow: hidden;
transition: height 0.3s;
}
.element.open {
height: calc-size(auto);
}
```
By wrapping the `auto` value in the `calc-size()` function, we can now animate the height of an element from 0 to `auto` without any JavaScript. Here's how it looks in action:
- **Normal Expansion**
- **Animated Expansion Using `calc-size()`**
### Limitations and Workarounds
It's important to note that you cannot animate between two automatically calculated values, such as `auto` and `min-content`. However, you can use `calc-size()` on non-automatic values within animations, ensuring smooth transitions:
```css
.element {
height: calc-size(0px);
overflow: hidden;
transition: height 0.3s;
}
.element.open {
height: auto;
}
```
### Advanced Calculations
While the primary use case for `calc-size()` is animations, it also supports more complex calculations:
```css
.element {
width: calc-size(min-content, size + 50px);
}
```
In this example, the width of the element is set to the minimum content size plus 50px. The syntax involves two arguments: the size to be calculated and the operation to perform. The `size` keyword represents the current size of the first property passed to `calc-size`.
You can even nest multiple `calc-size()` functions for more sophisticated calculations:
```css
.element {
width: calc-size(calc-size(min-content, size + 50px), size * 2);
}
```
This calculates the min-content size, adds 50px, and then doubles the result.
### Browser Support
Currently, `calc-size()` is only supported in Chrome Canary with the `#enable-experimental-web-platform-features` flag enabled. As it's a progressive enhancement, using it won't break your site in unsupported browsers—it simply won't animate.
Here's how you can implement it:
```css
.element {
height: 0;
overflow: hidden;
transition: height 0.3s;
}
.element.open {
height: auto;
height: calc-size(auto);
}
```
In supported browsers, the animation works seamlessly, while in others, the element will display without animation.
### Conclusion
The `calc-size()` function is a fantastic addition to CSS, simplifying animations involving dynamic sizes and enabling previously impossible calculations. Although it's currently in an experimental stage, its potential to enhance web development is immense. We eagerly await full support across all browsers!
Stay tuned and start experimenting with `calc-size()` to elevate your CSS animations to new heights! | srijan_karki |

### Introduction
Relative imports can be cumbersome in large projects. Absolute imports simplify locating and referencing source files. This guide will show you how to set up absolute imports in a Vite-powered React app, configure your project, and set up VS Code IntelliSense.
### The Problem
Relative imports can lead to confusing paths like `import Home from "../../../components/Home";`. Moving files requires updating all related import paths, which is time-consuming. Absolute imports fix this by providing a fixed path, like `import Home from "@/components/Home";`, making the code easier to manage.
### Prerequisite
- Node.js and Vite installed
- Familiarity with ES6 import/export syntax
- Basic knowledge of React
### Setting up the Vite React Project for Absolute Imports
#### Creating a Vite React App
1. Run the command to create a new React app:
```bash
npm create vite@latest absolute-imports -- --template react
```
2. Navigate to your project directory:
```bash
cd absolute-imports
```
3. Install dependencies:
```bash
npm install
```
4. Start the development server:
```bash
npm run dev
```
#### Configuring the Project for Absolute Imports
1. Open `vite.config.js` and add the following configuration to resolve absolute imports:
```javascript
import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import path from "path";
export default defineConfig({
resolve: {
alias: {
"@": path.resolve(__dirname, "./src"),
},
},
plugins: [react()],
});
```
#### Configuring VS Code IntelliSense
1. Create or update `jsconfig.json` (or `tsconfig.json` for TypeScript) in the root of your project:
```json
{
"compilerOptions": {
"baseUrl": ".",
"paths": {
"@/*": ["src/*"]
}
}
}
```
2. Open your VS Code settings (`settings.json`) and add the following line to ensure IntelliSense uses non-relative imports:
```json
"javascript.preferences.importModuleSpecifier": "non-relative"
```
### Practical Tips
- Consistently use absolute imports to maintain a clean and manageable codebase.
- Regularly check and update your configurations to match project changes.
### Conclusion
Absolute imports simplify your project structure and make your codebase more maintainable. By following this guide, you can easily set up absolute imports in your Vite React app and enhance your development experience.

1,926,200 | Mastering Microservices: Node.js 12 Factor App Development | The 12 Factor App is a methodology for building software-as-a-service apps that emphasizes... | 0 | 2024-07-17T04:25:30 | https://dev.to/tkssharma/mastering-microservices-nodejs-12-factor-app-development-23d5 | nextjs, node, javascript, microservices |
{% embed https://www.youtube.com/watch?v=GjyxQBy2cNo %}
The 12 Factor App is a methodology for building software-as-a-service apps that emphasizes portability, scalability, and maintainability. Developed by engineers at Heroku, the 12-factor methodology is intended to standardize and streamline app development and deployment. Below are the twelve factors in detail:
### 1. **Codebase**
- **One codebase tracked in revision control, many deploys**
- There should be a single codebase for a project, which is tracked in a version control system like Git. Multiple environments (e.g., production, staging, development) should be different deployments of the same codebase.
### 2. **Dependencies**
- **Explicitly declare and isolate dependencies**
- All dependencies should be declared explicitly in a dependency declaration file (e.g., `requirements.txt` for Python, `package.json` for Node.js). Use a dependency management tool to ensure these dependencies are isolated and versioned properly.
### 3. **Config**
- **Store config in the environment**
- Configuration that varies between deploys (such as credentials or resource handles) should be stored in the environment. This separates config from code, allowing for different configurations in different environments.
### 4. **Backing Services**
- **Treat backing services as attached resources**
- Backing services (e.g., databases, messaging systems, caches) should be treated as attached resources that can be attached and detached as needed, without making changes to the app's code.
### 5. **Build, Release, Run**
- **Strictly separate build and run stages**
- The build stage converts a code repo into an executable bundle (e.g., compiling code). The release stage takes the build and combines it with the current config to create a release. The run stage runs the app in the execution environment.
### 6. **Processes**
- **Execute the app as one or more stateless processes**
- The app should run as stateless processes, with any persistent data stored in a stateful backing service. This allows for easy scaling and resilience.
### 7. **Port Binding**
- **Export services via port binding**
- The app should be self-contained and make services available by listening on a port. This makes the app independent of the execution environment and easy to run.
### 8. **Concurrency**
- **Scale out via the process model**
- The app should be designed to scale out by running multiple instances of its processes. Use a process management tool to manage these processes effectively.
### 9. **Disposability**
- **Maximize robustness with fast startup and graceful shutdown**
- The app's processes should start up quickly and shut down gracefully. This improves resilience and allows for rapid deployment of changes.
### 10. **Dev/Prod Parity**
- **Keep development, staging, and production as similar as possible**
- Minimize the differences between development and production environments to catch issues early and ensure smoother deployments.
### 11. **Logs**
- **Treat logs as event streams**
- The app should not manage or write log files. Instead, it should treat logs as event streams that are sent to a centralized logging service for aggregation and analysis.
### 12. **Admin Processes**
- **Run admin/management tasks as one-off processes**
- Administrative or management tasks (e.g., database migrations) should be run as one-off processes in the same environment as the app, using the same codebase and config.
Adhering to these principles helps developers create applications that are more scalable, maintainable, and portable across different environments, ensuring a smoother development and deployment process. | tkssharma |

prompt = f"Create marketing content about {topic}."
response = openai.Completion.create(
engine="text-davinci-004", # Specify the GPT-4 engine
prompt=prompt,
max_tokens=150,
temperature=0.7
)
generated_text = response.choices[0].text.strip()
return generated_text

topic = "new product launch"
marketing_content = generate_marketing_content(topic)
print("Generated Marketing Content:")

#### Network Devices
1. **Switches**: Switches are the fundamental building blocks of a data center network. They connect different devices within the data center, facilitating data transfer and communication. Switches can be categorized into core, distribution, and access switches, each serving different layers of the network.
2. **Routers**: Routers connect the data center network to external networks, including the internet. They manage traffic between different networks and ensure data packets are delivered to their correct destinations.
3. **Firewalls**: Firewalls are critical for network security. They monitor and control incoming and outgoing network traffic based on predetermined security rules, protecting the data center from unauthorized access and cyber threats.
4. **Load Balancers**: Load balancers distribute network traffic across multiple servers, ensuring no single server is overwhelmed with too much traffic. This improves the overall performance and reliability of the data center.
5. **Storage Devices**: Storage Area Networks (SANs) and Network-Attached Storage (NAS) devices are used to store and manage large volumes of data. These devices ensure data is readily available for processing and retrieval.
#### Network Topologies
Network topology refers to the arrangement of various network devices and how they are interconnected. Several topologies are commonly used in data center networks, each with its advantages and disadvantages.
1. **Three-Tier Architecture**: This traditional architecture consists of three layers: core, distribution, and access. The core layer provides high-speed connectivity between different parts of the data center, the distribution layer aggregates traffic from the access layer, and the access layer connects end devices, such as servers.
2. **Leaf-Spine Architecture**: This modern topology addresses the limitations of the three-tier architecture, providing more efficient and scalable network performance. It consists of leaf switches (access layer) and spine switches (core layer). Every leaf switch connects to every spine switch, reducing latency and bottlenecks.
3. **Mesh Topology**: In a mesh topology, every network device is interconnected, providing multiple paths for data to travel. This topology offers high redundancy and fault tolerance but can be complex and expensive to implement.
4. **Ring Topology**: Devices are connected in a circular fashion, with each device connected to two other devices. This topology provides redundancy and is relatively easy to implement, but a failure in any single link can disrupt the entire network.
### Design Principles of Data Center Network Architecture
Designing an efficient and reliable data center network architecture requires adhering to several key principles. These principles ensure that the network can meet current demands while being scalable and adaptable to future requirements.
#### Scalability
Scalability is the ability of the network to grow and adapt to increasing demands. A scalable network can accommodate additional devices and increased traffic without significant performance degradation. This can be achieved through modular design, allowing easy addition of new switches, servers, and storage devices.
#### Redundancy and Fault Tolerance
Redundancy involves having multiple pathways for data to travel, ensuring that the failure of a single component does not lead to network downtime. Fault tolerance is the ability of the network to continue operating correctly even in the event of hardware or software failures. Implementing redundant power supplies, network links, and hardware components can achieve this.
#### Performance and Low Latency
Data center networks must deliver high performance and low latency to ensure efficient data processing and communication. High-speed switches and routers, optimized network topologies, and efficient load balancing contribute to achieving these objectives.
#### Security
Security is paramount in data center networks to protect sensitive data and prevent unauthorized access. This involves implementing robust firewalls, intrusion detection systems, encryption, and access control mechanisms. Regular security audits and updates are also essential to address emerging threats.
#### Manageability
A data center network must be easy to manage and monitor. Network management tools and software provide visibility into network performance, identify bottlenecks, and facilitate troubleshooting. Automation tools can also help manage routine tasks, such as configuration changes and updates.
### Emerging Trends in Data Center Network Architecture
The rapid evolution of technology continues to shape data center network architecture. Several emerging trends are driving innovation and improving efficiency in modern data centers.
#### Software-Defined Networking (SDN)
SDN separates the control plane from the data plane, allowing network administrators to manage and configure the network through software rather than hardware. This approach provides greater flexibility, scalability, and automation, making it easier to manage large and complex data center networks.
#### Network Function Virtualization (NFV)
NFV involves virtualizing network functions, such as firewalls, load balancers, and routers, and running them on commodity hardware. This reduces the need for dedicated hardware, lowers costs, and increases the agility of the network.

1,926,216 | How to Debug Node.js Applications Like a Pro | After working with Node.js for several years, I've encountered and overcome numerous debugging... | 0 | 2024-07-17T05:01:26 | https://dev.to/ashishxcode/how-to-debug-nodejs-applications-like-a-pro-4aon | webdev, javascript, node, tutorial | After working with Node.js for several years, I've encountered and overcome numerous debugging challenges. This guide shares practical insights and techniques I've found effective. Whether you're new to Node.js or looking to refine your debugging skills, I hope these experiences prove useful.
## Console Logging: A Starting Point
Most developers start with console logging, and it's still a useful tool in many situations:
```javascript
function processUser(user) {
console.log('Processing user:', user);
if (user.age < 18) {
console.log('User is under 18');
return 'Too young';
}
console.log('User is adult, continuing...');
// More processing...
return 'Processed';
}
```
While effective for quick checks, this method can clutter your code. For more complex debugging, consider using the built-in Node.js debugger or IDE integration.
## Leveraging the Node.js Debugger
The Node.js debugger is a powerful tool that's often underutilized. Here's how to get started:
```bash
node --inspect-brk my-script.js
```
Then open Chrome and navigate to `chrome://inspect`. This allows you to use Chrome DevTools to debug your Node.js application, which is particularly useful for inspecting variables and stepping through code.
## IDE Integration: Streamlining the Process
Visual Studio Code offers excellent debugging capabilities for Node.js. A basic `launch.json` configuration that I've found useful is:
```json
{
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "Debug Current File",
"program": "${file}",
"skipFiles": ["<node_internals>/**"]
}
]
}
```
This setup allows you to debug the currently open file by pressing F5, which can significantly speed up the debugging process.
## Handling Asynchronous Code
Debugging asynchronous code can be challenging. Using async/await has made this process more straightforward:
```javascript
async function fetchUserData(userId) {
try {
const response = await fetch(`https://api.example.com/users/${userId}`);
const data = await response.json();
return data;
} catch (error) {
console.error('Failed to fetch user data:', error);
throw error;
}
}
```
When debugging async functions, setting breakpoints inside both the try block and the catch block can provide valuable insights into the execution flow.
## Memory Profiling
For performance issues, particularly memory leaks, heap snapshots can be invaluable:
```javascript
const heapdump = require('heapdump');
function takeHeapSnapshot() {
const filename = `heap-${Date.now()}.heapsnapshot`;
heapdump.writeSnapshot(filename, (err) => {
if (err) console.error('Failed to generate heap snapshot:', err);
else console.log(`Heap snapshot written to ${filename}`);
});
}
```
Analyzing these snapshots in Chrome DevTools can help identify memory issues.
## Code Quality with ESLint
ESLint can catch many potential issues before they become runtime errors. A basic configuration that I've found helpful:
```javascript
module.exports = {
env: {
node: true,
es2021: true,
},
extends: 'eslint:recommended',
rules: {
'no-unused-vars': ['error', { argsIgnorePattern: '^_' }],
'no-console': ['warn', { allow: ['warn', 'error'] }],
'eqeqeq': ['error', 'always'],
},
};
```
Running ESLint as part of your development workflow can prevent many common mistakes.
## Advanced Debugging Techniques
1. **Conditional Breakpoints**: Useful for debugging specific conditions within loops or frequently called functions.
2. **Logpoints**: Allow adding temporary logging without modifying code, which is particularly useful in production environments.
3. **Remote Debugging**: Essential for debugging deployed applications:
```bash
node --inspect=0.0.0.0:9229 app.js
```
Use SSH tunneling to connect securely from a local machine.
## Best Practices
From my experience, these practices have proven most effective:
1. **Structured Logging**: Tools like Winston or Pino provide more detailed and easily searchable logs.
2. **Type Checking**: TypeScript or JSDoc can catch many errors at compile-time.
3. **Comprehensive Testing**: Well-written tests often reveal bugs before they reach production.
4. **Modular Code**: Smaller, focused modules are generally easier to debug and maintain.
5. **Continuous Integration**: Automated testing and linting on every code push helps catch issues early.
Debugging is an ongoing learning process. Each project brings new challenges and opportunities to refine these skills. I hope these insights prove helpful in your Node.js development journey. | ashishxcode |
1,926,217 | Protecting Against SQL Injection: An Overview of Platform Measures | SQL injection is a notorious and prevalent form of cyberattack that targets the integrity and... | 0 | 2024-07-17T05:01:52 | https://dev.to/adityabhuyan/protecting-against-sql-injection-an-overview-of-platform-measures-23fe | sql, sqlinjection |
SQL injection is a notorious and prevalent form of cyberattack that targets the integrity and confidentiality of data stored in databases. By inserting malicious SQL code into input fields, attackers can manipulate queries, access unauthorized data, or even execute destructive operations. Given the serious risks posed by SQL injection, many platforms have implemented robust measures to safeguard against these attacks. This article explores the SQL injection prevention mechanisms in place across several major platforms, evaluating their effectiveness in mitigating these threats.
### 1\. Web Application Frameworks
#### 1.1. Django (Python)
Django is a high-level web framework for Python that emphasizes the rapid development and clean, pragmatic design. Django comes with a built-in ORM (Object-Relational Mapping) that automatically escapes SQL queries, effectively mitigating the risk of SQL injection.
**Measures:**
* **ORM (Object-Relational Mapping):** By using ORM, developers interact with the database using high-level Python objects instead of writing raw SQL queries. This abstraction ensures that inputs are properly sanitized before they are inserted into SQL queries.
* **Prepared Statements:** Django’s ORM supports parameterized queries, which separate SQL code from data, making it impossible for an attacker to alter the SQL query structure with malicious inputs.
* **Input Validation and Sanitization:** Django provides built-in tools for validating and sanitizing user inputs, reducing the likelihood of injecting malicious code.
**Effectiveness:**Django’s ORM and built-in security features provide a strong defense against SQL injection. By default, Django encourages best practices that minimize the risk of SQL injection, making it a reliable choice for secure web application development.
#### 1.2. ASP.NET (C#)
ASP.NET is a robust web application framework developed by Microsoft. It is widely used for building dynamic web applications and services. ASP.NET includes numerous security features to protect against SQL injection.
**Measures:**
* **Parameterized Queries:** ASP.NET promotes the use of parameterized queries through ADO.NET. This ensures that SQL commands and data are processed separately, preventing the execution of malicious code.
* **ORM (Entity Framework):** Similar to Django, ASP.NET’s Entity Framework abstracts database interactions, automatically escaping inputs and protecting against SQL injection.
* **Request Validation:** ASP.NET includes request validation features that inspect and sanitize inputs before processing, preventing harmful SQL code from being executed.
**Effectiveness:**ASP.NET’s reliance on parameterized queries and its ORM significantly reduce the risk of SQL injection. The framework’s security features are well-designed to encourage secure coding practices, making it effective in preventing SQL injection attacks.
#### 1.3. Ruby on Rails
Ruby on Rails, often simply Rails, is a web application framework written in Ruby. Rails follows the convention over configuration (CoC) principle and comes with built-in protections against SQL injection.
**Measures:**
* **Active Record:** Rails’ Active Record is an ORM that ensures SQL queries are generated securely, automatically escaping potentially dangerous inputs.
* **Parameterization:** Rails encourages the use of parameterized queries to separate SQL commands from data, preventing attackers from injecting malicious code.

1,926,218 | Apa itu Laravel Blueprint? | Laravel Blueprint adalah package untuk Laravel yang memudahkan pembuatan komponen aplikasi seperti... | 0 | 2024-07-17T06:25:57 | https://dev.to/mahib22/apa-itu-laravel-blueprint-5747 | laravel, blueprint | [Laravel Blueprint](https://blueprint.laravelshift.com) adalah package untuk Laravel yang memudahkan pembuatan komponen aplikasi seperti model, controller, dan migration menggunakan file definisi sederhana. Dengan Blueprint, Anda bisa mendefinisikan struktur aplikasi dalam format YAML dan menghasilkan kode yang diperlukan secara otomatis.
Kita akan coba latihan dengan studi kasus membuat toko sepatu.
Lakukan instalasi package dengan menjalankan perintah `composer require -W --dev laravel-shift/blueprint`. Kemudian jalankan perintah `php artisan blueprint:new`. Perintah tersebut akan menghasilkan sebuah file **draft.yaml**.
Buka file **draft.yaml** kemudian isi sebagai berikut.
```
models:
Category:
code: string unique
name: string
img: string
relationships:
hasMany: Shoe
Shoe:
code: string unique
name: string
description: text
price: integer
stock: integer
img: string
category_id: foreign
controllers:
CategoryController:
index:
query: all
render: category.index
show:
find: id
render: category.show
create:
render: category.create
store:
validate: code, name, img
save: category
redirect: category.index
edit:
find: id
render: category.edit
update:
find: id
validate: code, name, img
update: category
redirect: category.show
destroy:
find: id
delete: category
redirect: category.index
ShoeController:
index:
query: all
render: shoe.index
show:
find: id
render: shoe.show
create:
render: shoe.create
store:
validate: code, name, description, price, stock, img
save: shoe
redirect: shoe.index
edit:
find: id
render: shoe.edit
update:
find: id
validate: code, name, description, price, stock, img
update: shoe
redirect: shoe.show
destroy:
find: id
delete: shoe
redirect: shoe.index
```
Penjelasan dari kode tersebut:
- Category dan Shoe adalah nama model.
- code, name, dan img adalah kolom-kolom tabel categories.
- relationships hasMany menandakan bahwa tabel categories memiliki relasi one to many ke tabel shoes.
- code, name, description, price, stock dan img adalah kolom-kolom tabel shoes.
- category_id merupakan foreign key ke tabel categories.
- CategoryController dan ShoeController adalah nama controller.
- index, show, create, store, edit, update, destroy adalah metode-metode di controller.
- query: all berarti metode index akan mengambil semua entri di tabel.
- find: id berarti metode akan mencari entri berdasarkan ID.
- validate akan memvalidasi input.
- save, update, delete melakukan operasi pada model.
- render mengarahkan ke view tertentu.
- redirect mengarahkan ke route tertentu setelah operasi selesai.
Jika sudah selesai, jalankan perintah `php artisan blueprint:build`. Perintah ini akan menghasilkan:
- Model Category dan Shoe.
- Migration untuk membuat tabel categories dan shoes dengan kolom yang telah didefinisikan.
- Factory dan Seeder.
- Controller CategoryController dan ShoeController
Bagaimana jika kita memiliki perubahan pada file **draft.yaml**? Jalankan terlebih dahulu perintah `php artisan blueprint:erase`, perintah ini akan menghapus semua file yang sudah dibuat tadi. Kemudian jalankan kembali perintah `php artisan blueprint:build`.
Dengan menggunakan Laravel Blueprint, Anda bisa dengan cepat mendefinisikan dan menghasilkan struktur dasar aplikasi Anda tanpa menulis kode secara manual. Laravel Blueprint sangat berguna untuk mempercepat proses pengembangan awal dan menjaga konsistensi dalam kode yang dihasilkan. | mahib22 |

1,926,220 | Pulumi in Python: Translating Interpolation | Pulumi is a powerful tool for managing infrastructure as code, and its flexibility across different... | 0 | 2024-07-17T05:07:33 | https://dev.to/cdierkens/pulumi-in-python-translating-interpolation-8nh | python, typescript, pulumi, javascript | Pulumi is a powerful tool for managing infrastructure as code, and its flexibility across different languages makes it a popular choice among developers. While Pulumi's TypeScript syntax offers a clean and convenient way to handle `Outputs` and `Inputs`, translating these features to Python can be challenging. This article explores the nuances of using `pulumi.interpolate` in TypeScript and how to achieve similar functionality in Python.
## Pulumi Interpolate
In the TypeScript syntax of Pulumi, there is a clean approach for concatenating `Outputs`. It leverages tagged template literals, which are not available in Python. As per the [Pulumi reference docs](https://www.pulumi.com/docs/reference/pkg/nodejs/pulumi/pulumi/functions/interpolate.html), `interpolate` is similar to `concat` but is designed to be used as a tagged template expression. For example:
```ts
// 'server' and 'loadBalancer' are both resources that expose [Output] properties.
let val: Output<string> = pulumi.interpolate `http://${server.hostname}:${loadBalancer.port}`
```
As with `concat`, the 'placeholders' between `${}` can be any Inputs, i.e., they can be `Promise`s, `Output`s, or just plain JavaScript values.
Having done most of my Pulumi work in TypeScript, I frequently used the `pulumi.interpolate` tagged template literal whenever I needed to pass an `Input` into a new resource. Without giving it much thought, I used it extensively without comparing it deeply to `pulumi.concat` or `apply`. However, when I started working with Pulumi in Python and reached for `pulumi.interpolate`, I realized it was missing.
This prompted a deeper dive into understanding what it means to be an `Output` vs. an `Input` and how to translate:
```ts
pulumi.interpolate`http://${server.hostname}:${loadBalancer.port}`
```
to:
```ts
pulumi.concat('http://', server.hostname, ':', loadBalancer.port)
```
## Output
`Output`s are values from resources that may be populated or will resolve and be populated in the future. Because an `Output` is associated with the resource it comes from, an edge can be created when it's passed as an `Input` to `pulumi.interpolate` or `pulumi.concat`, and later used to create another resource. The dependency graph between resources, created by the `nodes (resources)` and their `edges (Output -> Input)`, allows Pulumi to create resources in the correct order and ensures that `Output`s are populated when needed by the next resource in the graph.
## Input
An input can be a raw value, a promise, or an `Output`. If an `Input` to a resource is an `Output`, then you have a reference to the resource where the `Output` was originally created. The fact that an `Input` can be an `Output` enables it to trace its dependencies.
Here's its type definition:
```ts
type Input<T> = T | Promise<T> | OutputInstance<T>;
```
## Tagged Template Literals in 30 Seconds
Here’s an example of how we could uppercase just the values (the "placeholders" between `${}`), without altering the literal string portion of the template literal:
```js
function uppercaseValues(strings, ...values) {
const result = [];
strings.forEach((string, i) => {
result.push(string);
if (i < values.length) {
result.push(values[i].toString().toUpperCase());
}
});
return result.join('');
}
const name = "Chris";
const hobby = "TypeScript";
console.log(uppercaseValues`Hello, my name is ${name} and I love ${hobby}.`);
// Output: "Hello, my name is CHRIS and I love TYPESCRIPT."
```
## Implementing `pulumi.interpolate`
Without knowing the exact source code, and expanding from the example above, we can imagine how to implement `pulumi.interpolate` on our own. It might look something like this:
```js
function interpolate(strings, ...values) {
const result = [];
strings.forEach((string, i) => {
result.push(string);
if (i < values.length) {
result.push(values[i]);
}
});
return pulumi.concat(...result);
}
```
All we did was replace the final `join` call with a call to `pulumi.concat`. If this were the implementation, we'd perform checks on whether raw strings need to be unwrapped from `Output` types, instead of operating just on the placeholders, which is what the [real implementation does](https://github.com/pulumi/pulumi/blob/100470d2e72f0c6d16d3cbba661e9509daf43bb8/sdk/nodejs/output.ts#L1072).
Its function definition in TypeScript is:
```ts
function interpolate(literals: TemplateStringsArray, ...placeholders: Input<any>[]): Output<string>;
```
which is very similar to `concat`:
```ts
function concat(...params: Input<any>[]): Output<string>
```
The lightbulb moment comes when you realize that you're really just forwarding along `Output` values and wrapping them in parent `Output`s.
## Back to Python
You can make some silly mistakes when porting `interpolate` over to `concat`. Let’s demonstrate with an example.
In TypeScript, I would have done this:
```ts
function get_image_name(imageRegistry: Repository, name: string, version: Input<string>) {
return pulumi.interpolate`${image_registry.repository_id}/${name}:${version}`
}
```
When porting to Python, I might end up with this:
```python
def get_image_tag(image_registry: Repository, name: str, version: Input[str]):
return pulumi.Output.concat(
image_registry.repository_id,
f"/{name}:{version}"
)
```
However, `interpolate` was iterating over every placeholder individually to create dependencies and resolve outputs. With our Python code, we’ve subtly lost that connection with the `version` argument. We need to break up our `Output`s manually and surface them as individual arguments to `pulumi.Output.concat`.
The corrected code would look like this:
```python
def get_image_tag(image_registry: Repository, name: str, version: Input[str]):
return pulumi.Output.concat(
image_registry.repository_id,
f"/{name}:",
version
)
```
Now, the version will be correctly included in the dependency graph, and we’ll be error-free!
## Conclusion
Translating `pulumi.interpolate` from TypeScript to Python requires a deeper understanding of how `Outputs` and `Inputs` work in Pulumi. While Python does not support tagged template literals, using `pulumi.concat` effectively allows us to achieve similar functionality. By manually managing dependencies and ensuring all `Output` values are properly handled, we can ensure our Pulumi code in Python is just as robust and efficient as in TypeScript. | cdierkens |
1,926,221 | Users in Database | Users SYS--> DBA Role + SYSDBA Role ( Startup / Maintenance activity ) --> Super... | 0 | 2024-07-17T06:41:49 | https://dev.to/technonotes/users-in-database-35b3 | ## Users
1. **_SYS_**--> DBA Role + SYSDBA Role ( Startup / Maintenance activity ) --> Super Master User
2. **_SYSTEM_**--> DBA Role --> Master users
3. 30 to 35 users will be created in default. desc dba_users; Mostly all will be locked and expired.
- Any users created , DBA will assign **_System Level Privileges_** & Object Level Privileges.
- what are all the System Level Privileges ( activities performed at DB side ) ? CREATE SESSION , CREATE TABLE.
- When a user tries to read the data of other user , then object level privilege comes into picture.
- **_Object Level Privileges_** --> enables users to access and change data's in the object.
- These System level privileges comes along **_with ADMIN option_**.
- These Object level privileges comes along **_with GRANT option_**.
grant CREATE SESSION to user1 with ADMIN OPTION; --> which very risky. Because this user can give access to any user.
grant select on USER2.T2 to user1 with GRANT option; --> which very risky. Because this user can give select access to any user.
- If we want to revoke the admin option (System level privileges) for the user which you have given then it will revoke only for that user , it won't revoke for other users. If the user as given access to other friends . So Manually you need to check in the audit and then manually you need to remove the access.
- If we want to revoke the Grant option (Object level privileges) , then it will revoke for that user and also for other user which is granted.
## Roles
- Create a role and assign the privileges to the role. Why ? If new users comes in and DBA can't provide privilege for each users who is coming.
> create roles ROLE1;
> grant select on HR.Employees to ROLE1;
> grant select on HR.Regions to ROLE1;
> grant select on HR.Locations to ROLE1;
> grant ROLE1 to user1;
> grant ROLE1 to user2; --> these are new users joining
> grant ROLE1 to user3; --> these are new users joining
#### one more on this ROLE
> grant select on HR.JOBS to user1;
> .
> .
> grant select on HR.JOBS to user100;
rather than the above one , we can provide to roles because roles are already assigned to user1,user2,user3
> grant select on HR.JOBS to ROLE1;
## Profiles & Quotas
- Quotas --> the space usage
- profiles --> we can further more restrictions like the CPU usage a user can use & how much logical reads & password complexity.
desc dba_profiles;
- 20 to 30 resources will be listed down in each profile.
- any user you create "DEFAULT" profile will be associated with the user.
desc dba_users;
- what are the resources ? Each resources you can specify.
#### create custom profile for users
- Like for DEVELOPERS, DBA's , app users .
- Grant the profile to user1.
> Alter user user1 profile dummy;
> select username, acccount_status, profile from dba_users where username = 'user1';
- You can increase the complexity for creating the user slowly after getting the knowledge like below :
- Even you can modify using alter user too ,
> alter user user1 profile dummy;
> alter user user1 quota 2g on users;
> alter user user1 default tablespace test1;
# Notes
1. sqlplus / as sysdba or sqlplus sys/password as sysdba
2. sqlplus system/password ( no need of any role )
Above both the users are used to perform DB and maintenance activities .
- DBSNMP user mostly used for OEM.
- "---------------------" this is 100 characters , just restrict to 40 letters/characters like " col PROFILE for a40; --> for is format.
# Command
show user
set pages 1000 lines 1000
col username for a20 --> for is format
/ --> last command will be executed
grant CREATE SESSION to user1;
grant CREATE TABLE to user1;
create table T1 (SLNO number(10))
insert into T1 value (1);
alter user user1 quota unlimited on USERS; & then commit ;--> UNLIMITED space is allocated.
grant select on USER2.T2 to user1;
grant insert on USER2.T2 to user1;
grant delete on USER2.T2 to user1;
select * FROM DBA_SYS_PRIVS where grantee in ('USER1');
select * FROM DBA_TAB_PRIVS where grantee in ('USER1');

Introduction
------------
The handling of user data is a critical aspect of operations for companies like Facebook and Google. With billions of users worldwide, these tech giants must employ advanced and sophisticated methods to store and secure data, ensuring privacy, integrity, and availability. This article explores the approaches and technologies used by Facebook and Google to manage user data, covering data storage, encryption, access control, regulatory compliance, and ongoing security measures.
Data Storage Methods
--------------------
### Facebook's Data Storage Techniques
Facebook manages a vast amount of data generated by its users, including posts, messages, photos, and videos. To handle this efficiently, Facebook employs a combination of distributed storage systems, such as Haystack and TAO.
#### Haystack
Haystack is Facebook’s high-performance object storage system designed specifically for storing photos. It addresses the limitations of traditional storage systems by reducing metadata overhead and optimizing the read/write processes. Haystack uses a log-structured approach to store metadata and image data in a single, contiguous block, allowing for faster retrieval and lower storage costs.
#### TAO
TAO (The Associations and Objects) is a geographically distributed data store that Facebook uses to handle the massive social graph consisting of users and their interactions. TAO provides a highly available and low-latency database infrastructure, supporting real-time read and write operations across multiple data centers.
### Google's Data Storage Techniques
Google, on the other hand, leverages its own set of proprietary technologies to manage user data across its vast ecosystem of services such as Search, Gmail, and YouTube.
#### Bigtable
Bigtable is Google’s distributed storage system designed for managing large-scale structured data. It supports various Google services by providing high availability, scalability, and low-latency access to petabytes of data. Bigtable's design allows for flexible storage options, accommodating different types of data, including time-series data and structured content.
#### Colossus
Colossus, the successor to the Google File System (GFS), is Google’s distributed file storage system. Colossus provides the foundation for storing and processing large amounts of data, supporting the extensive data requirements of Google’s search index, logs, and analytics.
Data Encryption
---------------
Both Facebook and Google place a significant emphasis on encryption to protect user data, both at rest and in transit.
### Facebook's Encryption Practices
Facebook uses a multi-layered approach to encryption, employing industry-standard protocols and practices.
#### Encryption at Rest
Data stored on Facebook’s servers is encrypted using Advanced Encryption Standard (AES) with 256-bit keys. This includes user content such as posts, messages, and media files. Additionally, sensitive data such as passwords and payment information is hashed and salted before storage.
#### Encryption in Transit
To protect data during transmission, Facebook uses Transport Layer Security (TLS) to encrypt data traveling between users’ devices and Facebook’s servers. This ensures that data cannot be intercepted or tampered with by malicious actors during transit.
### Google's Encryption Practices
Google also employs robust encryption mechanisms to safeguard user data.
#### Encryption at Rest
Google’s data encryption at rest includes the use of AES-256 and employs a hierarchical key management system to secure encryption keys. This approach ensures that even if a single key is compromised, the overall integrity of the encryption system remains intact.
#### Encryption in Transit
Google uses TLS for encrypting data in transit, ensuring that data traveling between users’ devices and Google’s servers is protected from eavesdropping and man-in-the-middle attacks. Additionally, Google’s infrastructure employs Perfect Forward Secrecy (PFS) to enhance the security of data transmission.
Access Control and Authentication
---------------------------------
Restricting access to user data is critical for maintaining privacy and security. Both Facebook and Google implement stringent access control mechanisms and authentication processes.
### Facebook's Access Control Measures
Facebook uses a role-based access control (RBAC) system to ensure that only authorized personnel can access user data.
#### Role-Based Access Control
RBAC allows Facebook to assign specific roles to employees, defining their level of access based on their job responsibilities. This minimizes the risk of unauthorized access and data breaches.
#### Two-Factor Authentication
To enhance the security of user accounts, Facebook offers two-factor authentication (2FA), requiring users to provide a second form of verification (such as a code sent to their mobile device) in addition to their password.
### Google's Access Control Measures
Google employs a similar approach, leveraging RBAC and multi-factor authentication (MFA) to protect user data.
#### Role-Based Access Control
Google’s RBAC system ensures that employees have access only to the data necessary for their roles, reducing the risk of internal data breaches.
#### Multi-Factor Authentication
Google offers MFA for user accounts, adding an extra layer of security. This can include the use of hardware security keys, authentication apps, or SMS codes.
Regulatory Compliance
---------------------
Compliance with data protection regulations is crucial for companies like Facebook and Google, given the global nature of their operations.
### Facebook's Compliance Efforts
Facebook is subject to various data protection regulations, including the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA).
#### GDPR Compliance
To comply with GDPR, Facebook has implemented measures to ensure user data privacy and security, such as providing users with the ability to access, correct, and delete their data. Facebook also conducts regular data protection impact assessments and maintains records of data processing activities.
#### CCPA Compliance
Under CCPA, Facebook provides users with transparency about the data it collects and processes, offering users the ability to opt out of data sales and to request the deletion of their data.
### Google's Compliance Efforts
Google also adheres to GDPR, CCPA, and other global data protection regulations.
#### GDPR Compliance
Google’s GDPR compliance includes measures such as data minimization, pseudonymization, and providing users with control over their data. Google also undergoes regular audits to ensure compliance with GDPR requirements.
#### CCPA Compliance
For CCPA, Google offers users the ability to manage their privacy settings, opt out of data sales, and request the deletion of their data. Google also provides transparency reports detailing its data collection and processing practices.
Ongoing Security Measures
-------------------------
Continuous improvement and monitoring are essential for maintaining data security. Facebook and Google invest heavily in security research and infrastructure to protect user data.
### Facebook's Security Measures
Facebook employs a multi-faceted approach to security, including regular security audits, vulnerability testing, and the use of advanced technologies such as artificial intelligence (AI) and machine learning (ML).
#### Security Audits and Penetration Testing
Facebook conducts regular security audits and penetration testing to identify and address vulnerabilities in its systems. This proactive approach helps prevent data breaches and ensures the robustness of Facebook’s security infrastructure.
#### Artificial Intelligence and Machine Learning
Facebook leverages AI and ML to detect and mitigate security threats in real-time. These technologies help identify suspicious activities, prevent account takeovers, and combat phishing and malware attacks.
### Google's Security Measures
Google’s security strategy also includes rigorous security audits, the use of advanced technologies, and a strong focus on user education.
#### Security Audits and Vulnerability Assessments
Google performs regular security audits and vulnerability assessments to identify and mitigate potential risks. These audits are conducted both internally and by third-party experts to ensure comprehensive coverage.
#### Advanced Technologies
Google uses AI and ML to enhance its security measures, detecting anomalies and potential threats in real-time. Google’s infrastructure also includes custom hardware security modules (HSMs) to protect encryption keys and sensitive data.
#### User Education
Google invests in educating users about security best practices, offering resources and tools to help users protect their accounts. This includes phishing protection features, security checkups, and guidelines for creating strong passwords.
Conclusion
----------
Storing and securing user data is a complex and critical task for tech giants like Facebook and Google. By employing advanced storage systems, robust encryption techniques, stringent access controls, and continuous security improvements, these companies strive to protect user data from various threats. Additionally, compliance with global data protection regulations ensures that users' privacy and rights are respected.

1,926,225 | Building Scalable Applications: Best Practices with Coding Examples | In today's fast-paced digital world, building scalable applications is essential for any business... | 0 | 2024-07-17T05:27:33 | https://dev.to/nitin-rachabathuni/building-scalable-applications-best-practices-with-coding-examples-6oi | In today's fast-paced digital world, building scalable applications is essential for any business aiming for growth and efficiency. As a senior developer with extensive experience in handling large-scale projects, I’d like to share some best practices for building scalable applications, complete with coding examples.
. Choose the Right Architecture
The foundation of a scalable application lies in its architecture. Microservices architecture, for instance, divides the application into smaller, independent services that can be developed, deployed, and scaled independently.
Example: Setting up a simple microservice
```
const express = require('express');
const app = express();
const port = 3000;
app.get('/api/user', (req, res) => {
res.send({ id: 1, name: 'John Doe' });
});
app.listen(port, () => {
console.log(`User service running on port ${port}`);
});
```
This basic Express server represents a microservice that can be scaled independently.
. Implement Load Balancing
To distribute incoming traffic and ensure no single server becomes a bottleneck, load balancing is crucial. Tools like Nginx or AWS Elastic Load Balancer can be used to achieve this.
```
Example: Nginx load balancer configuration
http {
upstream myapp {
server 192.168.1.1;
server 192.168.1.2;
server 192.168.1.3;
}
server {
listen 80;
location / {
proxy_pass http://myapp;
}
}
}
```
This configuration distributes incoming requests to multiple servers.
. Use Caching Efficiently
Caching reduces the load on your servers by storing frequently accessed data in memory. Redis and Memcached are popular choices.
Example: Using Redis for caching
```
const redis = require('redis');
const client = redis.createClient();
client.on('connect', () => {
console.log('Connected to Redis');
});
// Set cache
client.set('user:1', JSON.stringify({ id: 1, name: 'John Doe' }), 'EX', 3600);
// Get cache
client.get('user:1', (err, reply) => {
if (err) throw err;
console.log(JSON.parse(reply)); // Output: { id: 1, name: 'John Doe' }
});
```
. Optimize Database Queries
Efficient database queries are crucial for performance. Use indexing, avoid N+1 queries, and consider using a NoSQL database if it suits your application.
Example: Optimizing SQL queries
```
-- Adding an index to a users table on the email column
CREATE INDEX idx_email ON users(email);
-- Optimized query
SELECT id, name, email FROM users WHERE email = '[email protected]';
```
. Implement Asynchronous Processing
For tasks that don't need to be executed immediately, like sending emails or processing images, use asynchronous processing. Message queues like RabbitMQ or Apache Kafka can help.
Example: Using RabbitMQ for async processing
```
const amqp = require('amqplib/callback_api');
amqp.connect('amqp://localhost', (err, conn) => {
conn.createChannel((err, ch) => {
const q = 'task_queue';
ch.assertQueue(q, { durable: true });
ch.sendToQueue(q, Buffer.from('Hello World'), { persistent: true });
console.log(" [x] Sent 'Hello World'");
});
setTimeout(() => { conn.close(); process.exit(0) }, 500);
});
```
. Monitor and Scale Proactively
Monitoring tools like Prometheus, Grafana, or New Relic can provide insights into application performance. Use these insights to scale your application proactively.
Example: Basic Prometheus configuration
```
global:
scrape_interval: 15s
scrape_configs:
- job_name: 'node_exporter'
static_configs:
- targets: ['localhost:9100']
```
Conclusion
Building scalable applications requires careful planning and the right set of tools and practices. By choosing the right architecture, implementing load balancing, using caching efficiently, optimizing database queries, leveraging asynchronous processing, and monitoring your applications, you can ensure your applications are scalable and ready to handle growth.
Let's embrace these best practices to build robust and scalable applications that can stand the test of time.

##1. View Data dictionary :-
Every controller has a property called ViewData which is of type ViewDataDictionary.
**Problem with this approach:- **
**Typecasting :-** We can't access Name property of our Movie because each item in the dictionary is of type object so we need to explicitly cast it to the Movie.
**No compile time safety/ Null Reference exception:-** In controller, If we change the magic string from ViewData["Movie"] to ViewData["RandomMovie"], we have to remember to go back in the view and make this change here as well otherwise we will get a Non Reference Exception.
##2. ViewBag :-
May have this View Data in very 1st version of MVC and then ViewBag comes into the picture which is dynamic type but it also has the same problems like typecasting/casting and no compile time safety. So honestly, I have no idea why to use ViewBag as an improvement for View Data. So please do not use ViewData or ViewBag. If you want to pass data to the view just use the third approach I.e "Passing Model object to the View"

Taking on the Cloud Resume Challenge was both an exciting and challenging journey. From setting up cloud infrastructure to configuring CI/CD pipelines, every step had its unique hurdles. Here’s a detailed account of the challenges faced, how they were tackled, and the triumphs achieved along the way.
Certification Milestone
Starting with the AWS Cloud Practitioner certification was a steep learning curve. Transitioning from a sales background to cloud technology was no small feat. However, with structured study plans and interactive learning tools, I managed to grasp the fundamentals and pass the certification. Now, with my Solutions Architect Associate certification, things are much clearer, providing a solid foundation for tackling the Cloud Resume Challenge.
Crafting the Resume with HTML and CSS
Creating the resume in HTML and CSS was the initial step. Though I had basic knowledge, making the resume visually appealing was challenging. Using AI tools in VS Code, such as Cody AI and Aidar, provided real-time feedback, helping to refine the layout and styling. Additionally, WebSim was instrumental in testing and iterating the front-end design efficiently.
Hosting on Amazon S3 and Enabling HTTPS
Hosting the resume on Amazon S3 was straightforward, but enabling HTTPS using CloudFront and Route 53 presented significant challenges. Initially, using the S3 website endpoint resulted in 403 Forbidden errors. After switching to using the S3 bucket endpoint, I could set up Origin Access Identities (OAI) and secure access correctly. After tinkering for a long time, I finally managed to fix the issue.
Implementing the Visitor Counter
Adding a visitor counter involved integrating JavaScript, AWS Lambda, DynamoDB, and API Gateway. This was a complex task that required setting up several services and ensuring they communicated correctly. WebSim was again crucial for testing the interactions and ensuring functionality.

1,926,243 | **Rethinking My Career, and Life! | It’s 2024, and six months have already passed. I have been coding and building websites since 2017. I... | 0 | 2024-07-17T06:02:16 | https://dev.to/ivewor/rethinking-my-career-and-life-43o | career, webdev, javascript, wordpress |
It’s 2024, and six months have already passed. I have been coding and building websites since 2017. I won’t bore you with all the details, so let’s jump into the main part: why I should rethink everything.
## Career
As I mentioned, my professional career started in 2017. I was pursuing Chartered Accountancy after 12th grade, but due to some issues, I had to drop out, one reason being my interest in programming. I started learning on my own from the internet and got my first job in Chandigarh as a WordPress developer. Since then, I have been partially successful in transitioning to other technologies like pure backend or frontend.
One reason for my partial success was that I was able to make good money, at least for me. I got new contracts and projects as a freelancer because of my problem-solving skills and ability to create nice user interfaces without using pre-built templates.
Some might think there’s no problem-solving in WordPress, but speed is a major issue for WordPress website owners who rely heavily on plugins. I limit plugin usage by custom coding features, which became my selling point. Even though I lacked experience in PHP and never formally learned it, I managed by reading WordPress docs and looking at code.
In 2023, I joined a web shop full-time, earning 1 lakh every month. My expenses were less than 30%, and I saved the rest, but I chose to invest in personal side projects, which amounted to nothing and wasted every penny.
After three months, I got sick of the work because I wasn’t doing anything special for the past six years. I left the office to freelance for the same company and focus on side projects, but this cycle of working for three months and then leaving to work on side projects repeated without success.
Eventually, I ran out of money, and freelancing work was at its lowest. The company I worked for shut down because the owner couldn’t handle running both it and a therapy center. Then the marriage happened, and now it’s July 2024.
Although I got some freelancing work on Upwork, the platform is worse these days. I couldn’t focus on a full-time job even when it was enough for my living because of my business mindset, which never succeeded. I always thought I would succeed this time but always failed and burnt tons of money.
I also tried stock trading and investment but, being impatient, never tasted success. Now, whenever I look at job posts, I feel I can’t do anything. Even for JavaScript developer positions, they ask for skills I never heard of or never used. I stayed back from applying because I probably worked on some of those things but never knew the professional terms.
This is the main drawback of working too much with web shops and then looking for product-focused companies like most startups these days. Now, I’m 26, workless, and cannot apply for jobs because I don’t know everything they ask for.
I can apply for entry-level jobs, but in India, they don’t pay much, and I won’t be able to survive on that alone. So, it’s not worth it. If I look for a job outside India, basically remote jobs, the same technology gap exists, and I don’t have a degree. I’m just a high school graduate and nothing else.
Now, I’m in too much debt and can’t even focus on learning because every 30 days there’s a huge EMI to pay, and I can’t ask for help every month. My stress level is at an all-time high because of these things. I’m losing my hair every day. Life is at its worst spot right now, and it has been since mid-2023. But I have to take some action because there’s no option to leave everything behind.
## The Plan
Frankly speaking, I’m not sure what the plan is, but I have to do something because I never planned for my life to be what it is today. I have started learning new things, focusing on React.js and Next.js. There are lots of entry-level jobs in these technologies, and I can get very good in a short span if I just do it every day. If I get a job, it will super boost my progress, reaching a level in three months that might take a year if I do it myself.
I could write a lot more about this stuff, but this is the summary of everything going on. | ivewor |

In the rapidly evolving world of technology, businesses are continually searching for ways to enhance productivity, streamline processes, and maintain a competitive edge. One innovation that has been making significant waves in the development landscape is Microsoft PowerApps. This powerful tool is revolutionizing how organizations approach app development, democratizing the process and enabling even those without a technical background to create sophisticated, functional applications. Let's explore how PowerApps is transforming the development landscape.
### What is PowerApps?
Microsoft PowerApps is a suite of apps, services, connectors, and a data platform that provides a rapid development environment to build custom apps for your business needs. It allows users to create applications with a point-and-click approach to design, leveraging templates and drag-and-drop simplicity. These apps can then be connected to various data sources, including Microsoft’s Common Data Service (CDS), SharePoint, Dynamics 365, SQL Server, and other platforms.
### Democratization of App Development
One of the most significant impacts of PowerApps is the democratization of app development. Traditionally, developing a business application required a team of developers with specialized coding skills, which could be both time-consuming and expensive. PowerApps breaks down these barriers by enabling “citizen developers”—individuals within an organization who may not have formal coding experience—to create and deploy apps.
The intuitive interface of PowerApps allows users to design applications through a visual builder, making the development process more accessible. With pre-built templates and easy-to-use tools, employees from various departments, such as HR, marketing, and finance, can develop applications tailored to their specific needs without relying on IT departments or external developers.
### Accelerating Time to Market
Speed is a critical factor in today’s business environment. PowerApps significantly accelerates the development lifecycle, allowing businesses to respond to market demands and internal requirements swiftly. The platform’s low-code nature means that apps that previously took months to develop can now be built in weeks or even days.
Furthermore, PowerApps integrates seamlessly with other Microsoft products and services, reducing the time needed for integration and deployment. This synergy ensures that businesses can leverage existing investments in Microsoft technologies while quickly creating new solutions to enhance productivity and efficiency.
### Enhancing Collaboration and Innovation
PowerApps fosters a culture of collaboration and innovation within organizations. By enabling a broader range of employees to participate in the app development process, it encourages diverse perspectives and ideas. Teams can work together to identify pain points and develop applications that address specific challenges, leading to more effective and innovative solutions.
The platform also supports collaboration through its integration with Microsoft Teams. Users can share apps, gather feedback, and iterate on solutions in a collaborative environment, promoting continuous improvement and innovation.
### Cost-Effective Solution
Cost is a crucial consideration for any business initiative. Traditional app development can be expensive, with costs associated with hiring skilled developers, maintaining infrastructure, and ongoing support. PowerApps offers a cost-effective alternative by reducing the need for extensive coding expertise and leveraging cloud-based infrastructure.
Organizations can also benefit from the scalability of PowerApps. As needs evolve, businesses can scale their applications without significant additional investment, ensuring they only pay for what they use. This cost-efficiency makes PowerApps an attractive option for businesses of all sizes, from small startups to large enterprises.
### Integration with Existing Systems
One of the standout features of PowerApps is its ability to integrate seamlessly with a wide range of data sources and systems. Businesses often have multiple systems in place, and the ability to connect these systems is crucial for creating cohesive and functional applications.
PowerApps offers connectors to numerous data sources, both within the Microsoft ecosystem and beyond. Whether it’s integrating with SharePoint for document management, Dynamics 365 for CRM, or external databases like SQL Server, PowerApps provides the flexibility needed to create comprehensive applications that bridge various systems and data silos.
### Security and Compliance
In an era where data security and compliance are paramount, PowerApps provides robust security features to ensure that applications and data are protected. Built on the Microsoft Azure platform, PowerApps inherits the security, compliance, and governance features of Azure, offering enterprise-grade security.
PowerApps also supports role-based access control, ensuring that only authorized users can access sensitive data and functionality. This level of control is essential for businesses operating in regulated industries, where compliance with standards like GDPR, HIPAA, and others is critical.

1,926,240 | Handling Outliers|| Feature Engineering || Machine Learning | Hey reader👋Hope you are doing well😊 We know that to improve performance machine learning model... | 0 | 2024-07-17T05:56:08 | https://dev.to/ngneha09/handling-outliers-feature-engineering-machine-learning-3316 | datascience, machinelearning, beginners, tutorial | Hey reader👋Hope you are doing well😊
We know that to improve performance machine learning model feature engineering is crucial step. One of most important tasks in feature engineering is handling outliers. In this blog we are going to do a detailed discussion on handling outliers. So let's get started 🔥.
## What are Outliers?
Outliers are extreme values that differ from most other data points in a dataset. They can have big impact on statistical analysis and skew the result of any hypothesis test.
To understand it better let's consider an example-:
Dataset A = [1,2,3,4,5,6]
Mean => 3.75
Now let's some more datapoints in the dataset.
A = [1,2,3,4,5,6,100,101]
Mean => 27.75
So here we can see that the mean is very much high just by adding two points and these two points are very different from rest of the other points in dataset, these points are definitely outliers.
The outliers can negatively affect our data and modeling so it is very important to properly handle them.
## How Outliers are introduced in Data?
Outliers in a dataset can be introduced through various mechanisms, both intentional and unintentional. Here are some common ways outliers can be introduced:
- Human Error: Manual data entry mistakes, such as typing errors, can lead to outliers. For example, entering an extra zero or a decimal point in the wrong place.
- Instrument Error: Faulty measurement instruments or sensors can produce erroneous values that stand out as outliers.
- Rare Events: Some outliers occur naturally due to rare events or extreme conditions. For example, an unusually high sales figure during a holiday season.
- Merging Datasets: Combining datasets with different scales or units without proper alignment or adjustment can introduce outliers.
- Intentional Manipulation: In some cases, outliers might be introduced intentionally, such as in fraudulent financial reporting or tampering with experimental data.
## Types of Outliers
Based on their characteristics, outliers or anomalies can be divided into three categories -:
**1. Global Outliers**
Any observations or data points are considered as global outliers if they deviate significantly from the rest of the observations or data points in a dataset. For example, if you are collecting observations of temperatures in a city, then a value of 100 degrees would be considered an outlier, as it is an extreme as well as impossible temperature value for a city.
**2. Contextual Outliers**
Any data points or observations are considered as contextual outliers if their value significantly deviates from the rest of the data points in a particular context. It means that the same values may not be considered an outlier in a different context. For example, if you have observations of temperatures in a city, then a value of 40 degrees would be considered an outlier in winter, but the same value might be part of the normal observations in summer.
**3. Collective Outliers**
Any group of observations or data points within a data set is considered collective outliers if these observations as a collection deviate significantly from the entire data set. It means that these values, individually without collection with other data points, are not considered as either contextual or global outliers.
## Identifying Outliers
There are four ways of identifying outliers -:
**1. Percentile Method**
The percentile method identifies outliers in a dataset by comparing each observation to the rest of the data using percentiles. In this method, We first define the upper and lower bounds of a dataset using the desired percentiles.
For example, we may use the 5th and 95th percentile for a dataset's lower and upper bounds, respectively. Any observations or data points that reside beyond and outside of these bounds can be considered outliers.
This method is simple and useful for identifying outliers in symmetrical and normal distributions.
**2. Inter Quartile Range (IQR) Method**
This method is similar to Percentile method, a slight difference is here we define an Inter Quartile Range for detecting outliers.
Q1 = 25th percentile
Q3 = 75th percentile
IQR = Q3-Q1
Upper bound = Q3+1.5*(IQR)
Lower bound = Q1-1.5*(IQR)
We check every datapoint ,if the point is in range [Lower bound ,Upper bound] then it is a valid point otherwise it is an outlier.
We are considering 25th and 75th percentile here because we are assuming that our data is normally distributed and most of our data resides in this range.
**3. Using Visualization**
In python we can use box plot or whisker plot to detect outliers in a dataset.
The box plot just gives the visualization of IQR method.
**4. Using Z score method**
For a given value, the respective z-score represents its distance in terms of the standard deviation. For example, a z-score of 2 represents that the data point is 2 standard deviations away from the mean. To detect the outliers using the z-score, we can define the lower and upper bounds of the dataset. The upper bound is defined as z = 3, and the lower bound is defined as z = -3. This means any value more than 3 standard deviations away from the mean will be considered an outlier.
## Python Implementation for detecting outliers
## Handling Outliers
Depending on the dataset there are various ways to handle outliers-:
- **Removing Outliers**
If the outliers are because of manual error it is better to remove them entirely from dataset. If dataset contains large number of outliers then removing them may result in loss of data.
- **Transforming Outliers**
The impact of outliers can be reduced or eliminated by transforming the feature. For example, a log transformation of a feature can reduce the skewness in the data, reducing the impact of outliers.
(We will read about transformations in upcoming blogs)
- **Impute Outliers**
In this outliers are considered as missing values and we can replace them with mean, median, mode, nearest neighbor etc.
- **Use robust statistical methods**
Some of the statistical methods are less sensitive to outliers and can provide more reliable results when outliers are present in the data. For example, we can use median and IQR for the statistical analysis as they are not affected by the outlier’s presence. This way we can minimize the impact of outliers in statistical analysis.
## Python Implementation of Handling Outliers
I hope you have understood that how outliers are handled in our dataset. In the next blog we are going to read about how to handle missing values. Till then stay connected and don't forget to follow me.

This initiative, launched by the Government of India to formalize micro, small, and medium enterprises (MSMEs), has been particularly transformative in rural regions where traditional industries and artisanal crafts form the backbone of the economy. In rural India, where agriculture has historically dominated, Udyam Registration has opened new avenues for diversification and industrialization. Many rural entrepreneurs, previously operating informally or as part of the unorganized sector, have embraced Udyam Registration to gain formal recognition and access to government support schemes.
One of the most significant impacts of Udyam Registration in rural areas has been on job creation. By formalizing small businesses, the initiative has not only preserved existing jobs but also created new employment opportunities. For instance, artisan clusters specializing in handicrafts, handloom, and cottage industries have leveraged Udyam Registration to expand their market reach. This formalization has attracted investments, both domestic and international, leading to increased production capacity and higher demand for skilled and unskilled labor. Another critical aspect of Udyam Registration is its role in promoting entrepreneurship among rural youth and women. By providing formal recognition and access to credit, the initiative has empowered aspiring entrepreneurs to establish and expand their ventures. This has not only diversified the local economy but also empowered marginalized groups, such as women artisans and tribal communities, to participate more actively in economic activities. Furthermore, Udyam Registration has enhanced market linkages for rural enterprises. Through government procurement policies favoring MSMEs, registered units have secured contracts for supplying goods and services to various government departments and agencies. This has not only boosted their revenues but also enhanced their credibility and visibility in national and international markets.
UDYAM REGISTRATION: ROLE OF MSMEs IN SUSTAINABLE DEVELOPMENT
Udyam Registration has emerged as a crucial catalyst for promoting sustainable development through micro, small, and medium enterprises (MSMEs) in India. Firstly, Udyam Registration formalizes MSMEs, providing them with legal recognition and access to various government schemes and incentives aimed at promoting sustainable practices. By complying with environmental regulations and adopting sustainable technologies, registered MSMEs contribute to reducing their ecological footprint. This formalization also enables them to implement resource-efficient practices, such as waste management, energy conservation, and water recycling, which are essential for sustainable development. Secondly, MSMEs registered under Udyam Registration contribute significantly to local and regional development by generating employment opportunities.

<h2 class="wp-block-heading">Why Build an Inventory Database?</h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>An inventory database is essential for managing your stock efficiently. It helps in tracking product availability, managing orders, forecasting demand, and ensuring that you never run out of stock or overstock. By having a centralized system, you can ensure data consistency and make informed <a href="https://five.co/blog/create-a-product-database-in-3-steps/">product</a> decisions.</p>
<!-- /wp:paragraph -->
<!-- wp:separator -->
<hr class="wp-block-separator has-alpha-channel-opacity"/>
<!-- /wp:separator -->
<!-- wp:heading -->
<h2 class="wp-block-heading">What Is an Inventory Database?</h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>An inventory database stores detailed information or attributes about items in your inventory, such as item name, weight, color, material, size, price, discount levels, minimum order quantity, country of origin, images, category, description, packaging information, margin, production cost, supplier details, and variations.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>Depending on your industry, your list of inventory attributes might include certifications (e.g., "certified organic," "GMO-free"), sensory characteristics (e.g., "sweet," "soft"), ingredients, or marketing claims (e.g., "long-lasting," "top-rated," "popular choice").</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>For instance, imagine you manage an e-commerce business that sells office supplies. On platforms like Shopify, your inventory items, such as pens, notebooks, and folders, can have various attributes and variations, such as price, color, size, and material quality. However, platforms like Shopify might not allow you to store extensive information such as granular item IDs, suppliers, inputs (materials or ingredients), production cost, margin, or required packaging materials.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>This is where your inventory database becomes essential: it serves as a comprehensive, <a href="https://five.co/blog/create-an-online-searchable-database/">searchable database</a> that stores all attributes about your inventory items, enabling efficient management and detailed tracking of all necessary information.</p>

<h2 class="wp-block-heading">How to Create an Inventory Database in 3 Steps</h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>Building an inventory database usually requires technical knowledge that someone running an e-commerce or factory operation might not have. For instance, you'd need a substantial understanding of database languages like <a href="https://five.co/blog/how-to-create-a-front-end-for-a-mysql-database/">SQL</a>, not to mention the frontend development for user interaction.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>This complexity often leads small-scale e-commerce operations, manufacturers, and distributors to neglect building an inventory database because they simply don't have the technical expertise or the time to create it from scratch.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>This is where database builders like Five come in. Five is an online database builder specifically designed to make creating an inventory database much faster.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>Creating an inventory database with Five won't be entirely effortless, but it will be significantly easier than spending 60+ hours learning various coding frameworks and languages.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>With Five, you can set up your database in minutes, and a user-friendly interface is automatically generated based on your database. You can easily import your existing data from Excel, Google Sheets, or CSV files, allowing you to get started quickly.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>Five also offers the flexibility to create custom business logic with code, generate stocktake or inventory <a href="https://five.co/blog/generate-mysql-pdf-report/">PDF reports</a>, and visualize your data through custom charts. Additionally, you can set up email notifications for low stock items, ensuring you stay organized and never run out of essential inventory.</p>

<h3 class="wp-block-heading">Step 1: List Out All Product and Inventory Attributes</h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>Start by compiling a complete list of all attributes relevant to your inventory. Think about what matters to your business, your customers, and your employees. Your inventory database should be a "single source of truth" about your items, so ensure it's as comprehensive as possible.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>Here are some must-have attributes typically included:</p>
<!-- /wp:paragraph -->

<ul><!-- wp:list-item -->

<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading">Step 2: Define Choices for Each Attribute</h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>Next, wherever possible, define choices for each attribute. This step introduces consistency into your database.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>For example, if your items come in different widths, decide whether to express width in centimeters, millimeters, or inches. If you need to cater to both American and European customers, store both measurements but in separate columns.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>Similarly, for colors, establish predefined choices like green, blue, and yellow. If you need to be more specific (e.g., dark green, forest green, olive green), define these variations as well.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>The benefits of defining choices include:</p>
<!-- /wp:paragraph -->
<!-- wp:list -->
<ul><!-- wp:list-item -->
<li><strong>Data Consistency</strong>: Ensures uniform data entry.</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li><strong>Clean Data</strong>: Prevents errors and inconsistencies.</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li><strong>Easier Data Management</strong>: Simplifies sorting and filtering data.</li>
<!-- /wp:list-item --></ul>
<!-- /wp:list -->
<!-- wp:paragraph -->
<p>With these first two steps, your inventory database table might look something like this:</p>
<!-- /wp:paragraph -->
<!-- wp:table -->
<figure class="wp-block-table"><table><thead><tr><th>Item Name</th><th>Description</th><th>Color</th><th>Weight</th><th>Size</th><th>Supplier</th><th>SKU</th><th>Price</th></tr></thead><tbody><tr><td>Item A</td><td>Detailed description of Item A</td><td>Black</td><td>350g</td><td>Large</td><td>Supplier1</td><td>12345678</td><td>$10.99</td></tr><tr><td>Item B</td><td>Detailed description of Item B</td><td>Blue</td><td>500g</td><td>Medium</td><td>Supplier2</td><td>23456789</td><td>$15.99</td></tr></tbody></table></figure>

<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading">Step 3: Creating Your Inventory Database</h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>When it's time to create your inventory database, many people start with tools like Microsoft Excel or Google Sheets. While these spreadsheet-based solutions can be convenient for smaller businesses, they often lead to significant issues as your operations grow. Here are some common problems associated with using spreadsheets:</p>
<!-- /wp:paragraph -->
<!-- wp:list -->
<ul><!-- wp:list-item -->
<li><strong>Version Confusion</strong>: Different departments or users might have their own local copy of the spreadsheet, leading to multiple versions like "InventoryDatabase_NEW," "Inventory Database – v2.1," "Old Inventory Database – DO NOT USE," etc.</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li><strong>Lack of Version Control</strong>: Without clear ownership or version control, changes made by different team members can be lost or duplicated, especially if the person responsible for updates leaves the company.</li>
<!-- /wp:list-item -->
<!-- wp:list-item -->
<li><strong>Data Inconsistencies</strong>: Comments, highlights, and manual updates can lead to a cluttered and error-prone spreadsheet. For example, marking out-of-stock items in red can easily be overlooked or misinterpreted.</li>
<!-- /wp:list-item --></ul>
<!-- /wp:list -->
<!-- wp:paragraph -->
<p>Setting up your inventory database in a spreadsheet can ultimately defeat the purpose of having a single, reliable source of truth. Instead of efficient inventory management, you end up constantly managing and cleaning up multiple spreadsheets.</p>

1,926,250 | AWS RDS Proxy For Aurora Global Database [MYSQL] | Using Amazon RDS Proxy, you can allow your applications to pool and share database connections to... | 0 | 2024-07-17T10:12:52 | https://dev.to/mizaniftee/aws-rds-proxy-for-aurora-global-database-mysql-561l | Using Amazon RDS Proxy, you can allow your applications to pool and share database connections to improve their ability to scale.
It does so in an active way first by understanding the database protocol. It then adjusts its behavior based on the SQL operations from your application and the result sets from the database.
**Quotas/Limitation:**
- you can have up to 20 proxies for each AWS account ID
- Each proxy has a default endpoint. You can also add up to 20 proxy endpoints for each proxy.
- Each proxy can have up to 200 associated Secrets Manager secrets
- RDS Proxy must be in the same virtual private cloud (VPC) as the database. The proxy can't be publicly accessible
- Each proxy can be associated with a single target DB cluster [For Primary need 1 and For Secondary Need another 1]
- can't use RDS Proxy with an RDS for MySQL DB instance that has the read_only parameter in its DB parameter group set to 1.
**Transactions By RDS Proxy:**
- Connection reuse can happen after each individual statement when the Aurora MySQL autocommit setting is turned on.
- Conversely, when the autocommit setting is turned off, the first statement you issue in a session begins a new transaction. For example, suppose that you enter a sequence of SELECT, INSERT, UPDATE, and other data manipulation language (DML) statements. In this case, connection reuse doesn't happen until you issue a COMMIT, ROLLBACK, or otherwise end the transaction.
- Entering a data definition language (DDL) statement causes the transaction to end after that statement completes.
**Failover:**
Without RDS Proxy, a failover involves a brief outage. During DB failovers, RDS Proxy continues to accept connections at the same IP address and automatically directs connections to the new primary DB instance. [When Failover happens, the secondary cluster becomes primary]
**When the database writer is unavailable, RDS Proxy queues up incoming requests.**
**IP Address Capacity For RDS Proxy:**
Aurora Global DB and RDS Proxy should be in same VPC should have a minimum of two subnets that are in different Availability Zones.
Following are the recommended minimum numbers of IP addresses to leave free in subnets for proxy based on DB instance class sizes.
In this case, assume the following:
- Aurora DB cluster has 1 writer instance of size db.r5.8xlarge and 1 reader instance of size db.r5.2xlarge.
- The proxy that's attached to this DB cluster has the default endpoint and 1 custom endpoint with the read-only role.
In this case, the proxy needs approximately 63 free IP addresses (45 for the writer instance, 15 for reader instance, and 3 for the additional custom endpoint).
**Database Credentials in AWS Secrets:**
For each proxy that we will create, we will first use the Secrets Manager service to store sets of user name and password credentials. Need to create a separate Secrets Manager secret for each database user account that the proxy connects to on the Aurora DB cluster.
To do this, you can use the setting Credentials for other database, Credentials for RDS database, or Other type of secrets.
Fill in the appropriate values for the User name and Password fields, and values for any other required fields.
> {"username":"db_user",
> "password":"db_user_password"}
**IAM Policy to access:**
After you create the secrets in Secrets Manager, you create an IAM policy that can access those secrets.
- You could create IAM Role automatically when you create the rds proxy.
- You could create policy first, then create role and add assign that role when creating the proxy
_Role Creation:_
then go for "**next**"
_Policy Creation:_
Use inline policy and add below
`{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "VisualEditor0",
"Effect": "Allow",
"Action": "secretsmanager:GetSecretValue",
"Resource": [
"arn:aws:secretsmanager:us-east-2:account_id:secret:secret_name_1",
"arn:aws:secretsmanager:us-east-2:account_id:secret:secret_name_2"
]
},
{
"Sid": "VisualEditor1",
"Effect": "Allow",
"Action": "kms:Decrypt",
"Resource": "arn:aws:kms:us-east-2:account_id:key/key_id",
"Condition": {
"StringEquals": {
"kms:ViaService": "secretsmanager.us-east-2.amazonaws.com"
}
}
}
]
}`
**Configuration Points: [Main Points]**
- _Idle client connection timeout_: Default time 1800s(30m) where a connection could be idle.A client connection is considered idle when the application doesn't submit a new request within the specified time after the previous request completed.
- _Connection pool maximum connections_: Specify a value from 1 through 100. This setting represents the percentage of the max_connections value that RDS Proxy can use for its connections.
- Like our Prod DB max connection is 4000, so what percentage we will set , rds proxy will use that [percentage*4000]/100
- _Connection borrow timeout_: If proxy use all available connection then can specify how long the proxy waits for a database connection to become available before returning a timeout error. We can specify a period up to a maximum of five minutes.
- _VPC security group_: must configure the Inbound rules to allow your applications to access the proxy. We must also configure the Outbound rules to allow traffic from our DB targets.
**Endpoint for RDS Proxy:**
- Each proxy handles connections to a single Aurora DB cluster. If Global DB has a Primary & Secondary Cluster, so you need two RDS Proxy in this regard.
- Add Reader Proxy Endpoint in RDS Proxy will create a read endpoint that points to Aurora DB Cluster Reader.
- Default [Read/Write] Proxy endpoint works with Write instance
- You could connect directly to DB or through RDS Proxy, but if we connect with RDS Proxy then you need to create secrets for every user.
**COST:**
RDS Proxy pricing correlates to the number of vCPUs for each database instance in your Aurora cluster.
If Aurora cluster that has a db.r6.large writer instance (2 vCPUs) and a db.r6.large reader instance (2 vCPUs $0.015 per vCPU-hour)
So, Monthly bill → 2,880 vCPU-hours (4 vCPU x 24 hours x 30 days)==$43.20

1,926,276 | Azure DevOps and "The term 'Install-Module' is not recognized" issue | Just a quick note in case it will help someone. =) The problem Since somewhere beginning... | 0 | 2024-07-17T06:47:11 | https://dev.to/kkazala/azure-devops-and-the-term-install-module-is-not-recognized-issue-30ck | devops, azure | Just a quick note in case it will help someone. =)
## The problem
Since somewhere beginning of July, I started noticing that my pipeline if failing **randomly** with `The term 'Install-Module' is not recognized as a name of a cmdlet, function, script file, or executable program.` error.
The pipeline is configured as follows:
### mypipeline.yaml
```yaml
- job: ExportLists
displayName: Export Lists from ${{ parameters.exportFrom }}
pool:
vmImage: 'ubuntu-latest'
steps:
- task: AzurePowerShell@5
name: DeploySPFx
inputs:
azureSubscription: $(serviceConnection)
azurePowerShellVersion: LatestVersion
ScriptType: FilePath
ScriptPath: $(Build.SourcesDirectory)/Pipelines/scripts/SPO-ExportLists.ps1
ScriptArguments: >
-tenantName '$(Az_TenantName)'
-siteName '$(SPO_SiteName)'
-folderPath '$(Build.SourcesDirectory)/SPO/templates'
displayName: Export lists
```
The PowerShell script WAS like that:
###ExportLists.ps1
```powershell
[CmdletBinding()]
param(
$tenantName,
$siteName,
$folderPath
)
Install-Module -Name PnP.PowerShell -Scope CurrentUser `
-SkipPublisherCheck -Force
#.....
```
And depending on the day the script sometimes worked, sometimes it didn't.
Occasionally, different jobs in the same stage would either succeed or fail on the `Install-Module` command.
## Troubleshooting
According to the [Ubuntu 22.04](https://github.com/actions/runner-images/blob/ubuntu22/20240624.1/images/ubuntu/Ubuntu2204-Readme.md), this image comes with **PowerShell 7.4.3**, and
>PowerShell 7.4 includes **Microsoft.PowerShell.PSResourceGet** v1.0.1. This module is installed side-by-side with **PowerShellGet **v2.2.5 and **PackageManagement **v1.4.8.1.
I see no reason for `Install-Module` failing, and ... why so randomly.
## The solution
I changed my code to call `Get-Module` and now the script looks like that:
###ExportLists.ps1
```powershell
[CmdletBinding()]
param(
[string]$tenantName,
[string]$siteName,
[string]$folderPath
)
Write-Host "##[group]Install PS modules"
Write-Host "##[command] Get Module PowerShellGet"
Get-Module -Name PowerShellGet -ListAvailable
Write-Host "##[command] Get Module PowerShellGet"
Get-Module -Name Microsoft.PowerShell.PSResourceGet -ListAvailable
Write-Host "##[command] Install PnP.PowerShell"
Install-Module -Name PnP.PowerShell -Scope CurrentUser -SkipPublisherCheck -Force
Write-Host "##[endgroup]"
```
And.. it works. Since whole three days already! Let's hope it will stay this way.🤞
Can someone explain it to me?
## Bonus content
If you are using **PnP.PowerShell** in your pipeline, and you have a Service Connection with Azure, you **don't have to authenticate to connect to SharePoint**.
The pipeline already runs in the context of the Service Principal.
**AzurePowerShell@5** accepts service connection as a parameter, and also runs in the context of the service principal.
All you need to do it to refresh the token in your PS script. Let me show you.
To get authentication context from the pipeline, you would call `Get-AzAccessToken` and connect to your SharePoint site using `Connect-PnPOnline -Url $url -AccessToken $azAccessToken.Token`.
###SPO-Auth.ps1
```powershell
function Connect-SPOSite {
param(
[Parameter(Mandatory = $true)]
[string] $tenantName,
[Parameter(Mandatory = $true)]
[string] $siteName
)
Write-Host "##[group]Who am I"
$azContext = (Get-AzContext).Account.Id
$sp = Get-AzADServicePrincipal -ApplicationId $azContext
Write-Host "##[debug] ServicePrincipal: $($sp.Id)"
Write-Host "##[endgroup]"
$url = "https://$tenantName.sharepoint.com"
Write-Host "##[debug]Connecting to $url"
try {
$azAccessToken = Get-AzAccessToken -ResourceUrl $url
Write-Host "##[debug]$azAccessToken"
$conn = Connect-PnPOnline -Url "$url/sites/$siteName" -AccessToken $azAccessToken.Token -ReturnConnection
Write-Host "##[debug]Get-PnPConnection"
Write-Host "##[debug]$($conn.Url)"
return $conn
}
catch {
Write-Host "##[error]$($_.Exception.Message)"
}
}
```
From this moment on, your PnP commands may use the connection returned by SPO-Auth.ps1:
###ExportLists.ps1
```powershell
[CmdletBinding()]
param(
$tenantName,
$siteName,
$folderPath
)
Write-Host "##[group]Install PS modules"
Write-Host "##[command] Get Module PowerShellGet"
Get-Module -Name PowerShellGet -ListAvailable
Write-Host "##[command] Get Module PowerShellGet"
Get-Module -Name Microsoft.PowerShell.PSResourceGet -ListAvailable
Write-Host "##[command] Install PnP.PowerShell"
Install-Module -Name PnP.PowerShell -Scope CurrentUser -SkipPublisherCheck -Force
Import-Module "$PSScriptRoot/_SPO-Auth.ps1"
Write-Host "##[endgroup]"
# This is the call to SPO-Auth.ps1
Write-Host "##[debug]Connecting to SharePoint Online"
$conn= Connect-SPOSite -tenantName $tenantName -siteName $siteName
# And here your code would start:
Get-PnPSiteTemplate -Out "$folderPath/SiteFields.xml" -Handlers Fields -connection $conn
```

In the always-changing world of... | 0 | 2024-07-17T06:43:56 | https://dev.to/astute_solutions_6b0813da/what-is-a-modern-data-platform-exploring-its-elements-features-more-56ea | data, moderndataplatforms | ## What is a Modern Data Platform and its Key Components?
In the always-changing world of data management, a Modern Data Platform has come out as a new way for organizations to use their data assets better. Basically, a Modern Data Platform is an all-in-one system that can grow and change easily. It’s made to bring in, handle, store, and examine data from many different places—whether the data is organized or not organized.
## The key components that make up a Modern Data Platform include:
**Data Ingestion:** This means collecting data smoothly from many different places, like databases, cloud services, IoT devices, and others. Today's platforms usually use real-time or batch methods to ensure the data is ready when needed.
**Data Storage:** The platform gives strong and expandable storage options, usually using techs like data lakes, data warehouses, and NoSQL databases. This helps to handle the increasing amount of data quickly from different types of sources.
**Data Processing:** The platform allows change, improve, and prepare data with strong processing abilities. It often uses distributed computing frameworks and in-memory processing to make data handling very fast and efficient.
**Data Analytics:** Today platforms give users the power to do advanced analytics, like predictive modeling, machine learning, and real-time insights. This helps organizations get useful knowledge from the data they can use for making decisions.
**Data Governance:** Good data governance is a very important part of a Modern Data Platform. It makes sure that the data stays safe, and private, and follows rules all through its life cycle.

1,926,279 | Compile modern C++ "Hello World" on mac | I was reading "A Tour of C++, Third Edition" and I found this "Hello World" example: import... | 0 | 2024-07-17T07:13:52 | https://dev.to/roeland/compile-modern-c-hello-world-on-mac-2pa | I was reading "A Tour of C++, Third Edition" and I found this "Hello World" example:
```c++
import std;
int main() {
std::cout << "Hello, World!\n";
}
```
I am completely new to C++ and I wanted to try this example.
I made a file "hello.cpp" with that content and I tried to compile it with clang like this: `clang hello.cpp`
This gives me the error "unknown type name 'import'" because I have to specify a newer C++ version. I can do that like this:
`clang --std=c++23 hello.cpp`
Unfortunately the default clang version is a bit too old and gives this error:
`invalid value 'c++23' in '--std=c++23'`
Luckily it is easy to install a new version of `clang` with `brew`:
`brew install llvm@17`
(The default llvm version is 18 at the moment, but that gives me this error: `import of module 'std' imported non C++20 importable modules`)
After installing there is some usage information about `LDFLAGS` and `CPPFLAGS`:
```bash
export LDFLAGS="-L/opt/homebrew/opt/llvm@17/lib/c++ -Wl,-rpath,/opt/homebrew/opt/llvm@17/lib/c++"
export CPPFLAGS="-I/opt/homebrew/opt/llvm@17/include"
```
Now I can compile my source like this:
`/opt/homebrew/Cellar/llvm@17/17.0.6/bin/clang++ --std=c++23 -fmodules ./hello.cpp`
(Don't forget `-fmodules`)
This results in "a.out" that I can finally run!
The next steps are probably using cmake and getting it working with vscode, but this is it for now.
Happy coding.
**Update:**
I tried getting it to work with clangd in vscode, but it seems modules is not yet supported: https://github.com/clangd/clangd/issues/1293
I had a .clangd file like this:
```yaml
CompileFlags:
Add: [-std=c++23, -fmodules, -L/opt/homebrew/opt/llvm@17/lib/c++, '-Wl,-rpath,/opt/homebrew/opt/llvm@17/lib/c++', -I/opt/homebrew/opt/llvm@17/include"]
Compiler: /opt/homebrew/Cellar/llvm@17/17.0.6/bin/clang++
```
And this in settings.json for the clangd extension:
`"clangd.path": "/opt/homebrew/Cellar/llvm@17/17.0.6/bin/clangd"`

1,926,280 | Objects in JavaScript : A Comprehensive Guide | Exploring Object Literals, Properties, Methods, and Object Destructuring, Custom constructors,... | 27,784 | 2024-07-17T06:36:47 | https://dev.to/sadanandgadwal/objects-in-javascript-a-comprehensive-guide-6n9 | webdev, javascript, beginners, sadanandgadwal |
Exploring Object Literals, Properties, Methods, and Object Destructuring, Custom constructors, Mechanism for inheritance and object, and Built-in Objects
JavaScript objects are fundamental to the language, serving as versatile containers for data and functionality. In this article, we'll explore the various aspects of objects, from their creation using object literals to more advanced topics like methods and destructuring.
**Object Literals: Creating Objects Simply**
Object literals are the most straight forward way to create objects in JavaScript. They allow you to define an object and its properties in a concise manner using curly braces {}.
```
// Example of an object literal
let person = {
firstName: 'Sadanand',
lastName: 'Gadwal',
age: 30,
greet: function() {
return `Hello, my name is ${this.firstName} ${this.lastName}.`;
}
};
```
In this example:
firstName, lastName, and age are properties of the object person.
greet is a method defined within the object, using a function expression.
**Accessing Object Properties**
You can access object properties using dot notation
(object.property) or bracket notation (object['property']).
```
console.log(person.firstName); // Output: Sadanand
console.log(person['age']); // Output: 30
console.log(person.greet()); // Output: Hello, my name is Sadanand.
```
**Adding and Modifying Properties**
Objects in JavaScript are mutable, so you can add new properties or modify existing ones after the object is created.
```
person.email = '[email protected]';
person.age = 23; // Modifying existing property
console.log(person.email); // Output: [email protected]
console.log(person.age); // Output: 23
```
**Object Methods: Adding Functionality**
Methods are functions defined within objects, allowing them to perform actions related to the object's data.
```
let car = {
brand: 'Mahindra',
model: 'Thar',
year: 2024,
displayInfo: function() {
return `${this.year} ${this.brand} ${this.model}`;
}
};
console.log(car.displayInfo()); // Output: 2024 Mahindra Thar
```
**Object Destructuring: Simplifying Access**
Object destructuring provides a concise way to extract properties from objects and bind them to variables.
```
let { firstName, lastName } = person;
console.log(firstName); // Output: Sadanand
console.log(lastName); // Output: Gadwal
```
**Real-World Example: Managing Products**
Imagine you're building an e-commerce website where you need to manage products. Each product can have various attributes like name, price, and category. You can use objects to represent these products:
```
let product1 = {
name: 'Laptop',
price: 105000,
category: 'Electronics',
getDescription: function() {
return `${this.name} - Rs ${this.price}`;
}
};
let product2 = {
name: 'Smartphone',
price: 60000,
category: 'Electronics',
getDescription: function() {
return `${this.name} - Rs ${this.price}`;
}
};
console.log(product1.getDescription()); // Output: Laptop - Rs 105000
console.log(product2.getDescription()); // Output: Smartphone - Rs 60000
Custom Constructors: Objects created using constructor functions with new keyword.
Custom constructors are functions used to create objects with specific properties and methods. They are invoked using the new keyword.
// Example of a constructor function
function Car(brand, model, year) {
this.brand = brand;
this.model = model;
this.year = year;
this.displayInfo = function() {
return `${this.year} ${this.brand} ${this.model}`;
};
}
// Creating objects using the constructor
let myCar = new Car('Tata', 'harrier', 2024);
let anotherCar = new Car('Mahindra', 'Thar', 2024);
console.log(myCar.displayInfo()); // Output: 2024 Tata Harrier
console.log(anotherCar.displayInfo()); // Output: 2024 Mahindra Thar
```
In this example:
- Car is a constructor function that defines how a Car object should be created.
- Properties (brand, model, year) are assigned using this.
- displayInfo method is defined within the constructor function to display car information.
- Custom constructors allow for creating multiple objects of the same type with shared properties and methods.
**Prototypes**: Mechanism for inheritance and object extension.
Prototypes in JavaScript enable object inheritance and extension. Every JavaScript object has a prototype property, which allows properties and methods to be inherited from another object.
```
// Example of using prototypes
function Person(firstName, lastName) {
this.firstName = firstName;
this.lastName = lastName;
}
Person.prototype.greet = function() {
return `Hello, my name is ${this.firstName} ${this.lastName}.`;
};
let person1 = new Person('Sadanand', 'Gadwal');
let person2 = new Person('Tushar', 'Chavan');
console.log(person1.greet()); // Output: Hello, my name is Sadanand Gadwal.
console.log(person2.greet()); // Output: Hello, my name is Tushar Chavan.
```
In this example:
- Person is a constructor function defining a Person object with firstName and lastName properties.
- greet method is added to Person.prototype, allowing all Person instances to access it.
- person1 and person2 are instances of Person that inherit the greet method from Person.prototype.
Prototypes facilitate efficient memory usage and promote code reusability through inheritance.
**Built-in Objects**: Standard objects like Array, Date, RegExp, etc., provided by JavaScript.
JavaScript provides built-in objects that serve common programming needs, such as working with arrays, dates, regular expressions, and more.
```
// Example of using built-in objects
let numbers = [1, 2, 3, 4, 5]; // Array object
let today = new Date(); // Date object
let pattern = /[a-zA-Z]+/; // RegExp object
console.log(numbers.length); // Output: 5
console.log(today.getFullYear()); // Output: current year
console.log(pattern.test('Hello')); // Output: true
```
In this example:
- numbers is an instance of the Array object used to store a list of numbers.
- today is an instance of the Date object representing the current date and time.
- pattern is an instance of the RegExp object used to match alphabetical characters in strings.
Built-in objects provide robust functionality for common tasks in JavaScript programming.
**Conclusion**
JavaScript objects are powerful constructs that allow you to encapsulate data and behavior into cohesive units. Whether you're creating simple data containers or modeling complex real-world entities, understanding objects is crucial for mastering JavaScript.
In this article, we've covered object literals for object creation, accessing properties and methods, modifying objects, object destructuring for convenient property extraction, and provided a practical example of using objects in a real-world scenario.
By mastering these concepts, you'll be well-equipped to leverage JavaScript's object-oriented capabilities effectively in your projects.

For more content, including extra downloadables and resources for this post — feel free to visit my [website](https://aedrielkylejavier.me/).*
⚠ Now, before anything, I personally wouldn't recommend **switching** to GNU `screen` **if** you already have a `tmux` configuration. I believe `tmux` excels in terms of extensibility, documentation, and community support, with numerous videos and guides available. This blog post is best suited for those who might **not** have a terminal multiplexer setup yet and are looking for something simple, built-in, and somewhat ["suckless"](https://suckless.org/philosophy/) 🧩.
GNU `screen` provides all the necessities of a terminal multiplexer with a few essential features and configurability options sprinkled on top ✨. If you don't foresee the need to heavily *extend* the tool, want to keep your setup straightforward, and aren't interested in creating elaborate configurations for [show](https://www.reddit.com/r/unixporn/), GNU `screen` might be perfect for those long SSH sessions and productive late nights with text editors like Neovim and other CLI tools.
In this post, I'll share my simple GNU Screen setup, which I find more than sufficient for my needs. I hope this post serves as a good starting point for anyone looking to configure a terminal multiplexer 👍.
## The Set-up
I have two concurrent GNU `screen` setups on my machines. One for when I am in a session where the `X11` display server is running (essentially, when using a graphical environment):
[](https://aedrielkylejavier.me/articles/img/gnu-screen-images/0.png)
And another for when I am in a TTY session (a text-based environment without a graphical interface):
[](https://aedrielkylejavier.me/articles/img/gnu-screen-images/1.png)
## The "Top Bar"
The `hardstatus` line consists of a few basic elements:
[](https://aedrielkylejavier.me/articles/img/gnu-screen-images/3.png)
[](https://aedrielkylejavier.me/articles/img/gnu-screen-images/2.png)
* **A** *(Top-left)* — a simple hard-coded `[ GNU screen ]` indicator to signify that you are in an attached session.
* **B** *(Middle-left)* — a horizontal "window buttons list" similar to a taskbar in a panel.
* The "Active Window" is represented within " `(==` " and " `==)` ".
* The X11 `screen` config has more *verbose* "window" titles.
* **C** *(Top-right)* — a "textclock" displaying the date, day, and time (only present in the `tty` config).
This setup is meant to be "functionally simple" and not reliant on any [Nerd Fonts](https://www.nerdfonts.com/) or other non-ASCII characters, so you can get up and running with a multiplexer even on a barebones Linux install.
## Keybindings
My preferred "prefix" key is `Ctrl`+`space` (instead of the default, `Ctrl`+`a`). This prefix key seems to conflict less with known default terminal programs’ keybindings unless it was explicitly set in said tools (e.g., in a VI/Vim/Neovim config). Here are some of my configuration's keybindings based on the common commands presented in the [ArchWiki](https://wiki.archlinux.org/title/GNU_Screen#Common_Commands).
| Keybind | Action |
|----------------------------------|----------------------------------------------------------------------------------------|
| Ctrl+space " | toggle window list |
| Ctrl+space 1 | open window 1 |
| Ctrl+space 0 | open window 10 |
| Ctrl+space ? | display commands and their defaults |
| Ctrl+space A | rename the current window |
| Ctrl+space Esc | enter copy mode (use enter to select a range of text) |
| Ctrl+space Q | close all regions but the current one |
| Ctrl+space S | split the current region horizontally into two regions |
| Ctrl+space ] | paste text |
| Ctrl+space a | send ctrl+a to the current window |
| Ctrl+space c | create a new window (with shell) |
| Ctrl+space d | detach from the current screen session and leave it running. use `screen -r` to resume |
| Ctrl+space k | "kill" the current window |
| Ctrl+space tab | switch the input focus to the next region |
| Ctrl+space \| | split the current region vertically into two regions |
| Ctrl+space : | enter the command prompt of screen |
| Ctrl+space :quit | close all windows and close the screen session |
| Ctrl+space :source | reload the screenrc configuration file (can alternatively use /etc/screenrc) |
## Replicate My GNU Screen Config 🚀
Due to my VI/Neovim configuration requiring True Color (24-bit) support, I use GNU Screen 5.0.0 (the -git master branch), which finally has the `truecolor` setting. For those who prefer not to compile software and would rather stick with the versions available in the repositories, I also have a similar configuration that works with `screen` versions `<= 4.9.1` (which only support 256 colors). I will share both configurations in this blog post.
## GNU Screen 5.0.0 (-git master branch)
[](https://aedrielkylejavier.me/articles/img/gnu-screen-images/0.png)

hardstatus alwaysfirstline
hardstatus string '%{= kW}[%{W} GNU screen %{W}]%{W} %< %{kW}%?%-Lw%?%{= kB}(== %{W}%n*%f %t%?(%u)%? %{kB}==)%{= kW}%?%+Lw%?%? %= %{kW}[%{W}%0` %{W}%1`%{kW}]'
altscreen on
bind 0 select 10
bind c screen 1
defscrollback 5000
escape ^@a
maptimeout 0
screen 1
startup_message off
```
## Dynamic `screen` Configuration Based on Session
On my machines, these configs are dynamically loaded based on session. I also follow the [XDG Base Directory Specification](https://specifications.freedesktop.org/basedir-spec/latest) by declaring the `SCREENRC=` environment variable, which moves the configuration from `~/.screenrc` to whatever path is specified in the variable.
If you would also like to load individual configs based on whether you're in an X11 or a TTY session, refer to this snippet of my `.config/shell/profile` :
```sh
#!/bin/sh
…
# X11-dependent env variables
if [ -n "$DISPLAY" ] && xhost >/dev/null; then
setxkbmap -option compose:ralt
xset r rate 300 50
export SCREENRC="$XDG_CONFIG_HOME"/screen/screenrc
export XPROFILE_X11_SPECIFICS=loaded
else # if TTY
export SCREENRC="$XDG_CONFIG_HOME"/screen/screenrc-if-tty
export XPROFILE_X11_SPECIFICS=unloaded
echo "X11 is not running... X11-related settings have been skipped"
fi
```
This file is sourced by my `fish` shell config (via a method similar to what is mentioned in the [ArchWiki](https://wiki.archlinux.org/title/Fish#Source_/etc/profile_on_login)). The file is also symlinked to `.zprofile`, `.profile`, and `.xprofile`/`.xsessionrc` in case I want to go back to using `zsh` or `bash` as my default shell again.
## Changing the "Prefix" Key
If you would like to have a different "prefix" key, you can run `showkey -a` to examine the codes sent by the keyboard and then grab the ASCII output, append an "a", and modify the config like so:
[](https://aedrielkylejavier.me/articles/img/gnu-screen-images/new-keybind.png)
*Output while pressing* `Ctrl`+`\`
**To apply, replace the `escape ^@a` line in the config with:**
```sh
escape ^\a
```
For more information on this, you can refer to the ArchWiki's "Change The Escape Key" [GNU Screen Article](https://wiki.archlinux.org/title/GNU_Screen#Change_the_escape_key).
## Wrapping Up 🎁
That's it for my simple GNU Screen setup! While GNU Screen might not be as feature-rich `tmux`, I believe it offers a straightforward and functional alternative for those who prefer simplicity and minimalism with their tools. The configurations shared here should provide a solid foundation to get you started. Feel free to experiment with the configs and make them your own.
Happy hacking, and may your terminal sessions be ever efficient and productive! 🚀

1,926,290 | 10 Common Mistakes Beginners Make | Introduction Starting a career in software development is both exciting and challenging. While... | 0 | 2024-07-17T06:49:11 | https://dev.to/ezilemdodana/10-common-mistakes-beginners-make-53c6 | programming, beginners, productivity | **Introduction**
Starting a career in software development is both exciting and challenging. While learning to code is crucial, understanding common pitfalls can help new developers navigate their journey more effectively. In this article, we will explore ten common mistakes that beginner software developers make and provide tips on how to avoid them.
**1. Not Asking for Help**
Many beginners feel intimidated about asking for help, fearing it might make them seem less competent. However, seeking assistance is a vital part of learning. Experienced developers, mentors, and even online communities can provide valuable insights and solutions to problems that might take hours to solve alone. Remember, asking questions is a sign of eagerness to learn and grow.
**2. Neglecting Code Readability**
Writing code that only you can understand is a common rookie mistake. Code readability is essential for collaboration and maintenance. Adopting best practices like using meaningful variable names, consistent indentation, and commenting on your code helps others (and your future self) understand your work. Following coding standards and guidelines also ensures that your code remains clean and maintainable.
**3. Overlooking Version Control**
Version control systems like Git are indispensable tools for developers. They allow you to track changes, collaborate with others, and revert to previous versions if something goes wrong. Despite its importance, many beginners avoid using version control due to perceived complexity. Start with basic Git commands like commit, push, pull, and branch, and gradually explore more advanced features.
**4. Skipping Testing**
Testing is often neglected by beginners, leading to unstable and buggy software. Writing tests ensures that your code works as intended and helps catch errors early. Start with unit tests to validate individual components, and gradually incorporate integration and automated tests. Tools like Jest for JavaScript, JUnit for Java, and PyTest for Python can help you get started.
**5. Ignoring Documentation**
Documentation is an often overlooked aspect of software development. It provides a roadmap for users and developers, explaining how the code works and how to use it. Whether it's inline comments, README files, or API documentation, take the time to document your code thoroughly. This practice not only helps others but also reinforces your understanding of the code.
**6. Not Understanding the Problem Before Coding**
Beginners may jump into coding without fully understanding the problem. It's essential to analyze and plan before writing code. Techniques like pseudocode, flowcharts, and diagrams can help clarify the problem and outline a solution. Taking the time to understand the problem can save a lot of rework and frustration later.
**7. Overcomplicating Solutions**
New developers might write overly complex solutions to simple problems. Advocate for simplicity and clarity in code. Introduce the KISS (Keep It Simple, Stupid) principle. Simple solutions are often more robust and easier to understand. Avoid over-engineering and focus on solving the problem at hand.
**8. Lack of Consistent Learning**
Some beginners stop learning once they get a job or complete a course. However, technology is always evolving, and continuous learning is essential. Stay updated with industry trends and best practices by reading books, taking online courses, and participating in coding challenges. Engage with the developer community through forums, blogs, and conferences.
**9. Underestimating the Importance of Soft Skills**
Technical skills are crucial, but soft skills like communication, teamwork, and time management are equally important. These skills can impact a developer's career and work environment significantly. Good communication ensures that ideas are clearly conveyed, and teamwork fosters a collaborative and productive environment. Managing your time effectively helps in meeting deadlines and balancing workloads.
**10. Failure to Review and Refactor Code**
Beginners often write code and move on without reviewing or refactoring. Code reviews are an excellent way to catch mistakes, get feedback, and learn from more experienced developers. Regularly refactoring code improves its structure and performance. Adopt a mindset of continuous improvement and seek opportunities to enhance your code.
**Conclusion**
By addressing these common mistakes and adopting best practices, beginner software developers can set themselves up for success. Continuous learning, seeking feedback, and being open to new ideas will help you grow and excel in your career. Embrace the journey, learn from your mistakes, and remember that every experienced developer started where you are now. | ezilemdodana |

1,926,293 | HarvestRealm: Ushering into a New Era of Virtual Farming and Social Interaction | In today's fast-paced digital world, people seek a tranquil escape. HarvestRealm answers this call,... | 0 | 2024-07-17T06:50:35 | https://dev.to/harvestrealm_official_/harvestrealm-ushering-into-a-new-era-of-virtual-farming-and-social-interaction-29gf | In today's fast-paced digital world, people seek a tranquil escape. HarvestRealm answers this call, providing a virtual countryside where players can unwind and appreciate nature. Developed by K70 Tribe, HarvestRealm embodies a vision of connecting players with nature through gaming, sparking a love for life and curiosity about the world.
Our mission is to create a game that balances realism with imagination. Players can enjoy farming, raising animals, and fishing while forming meaningful friendships. HarvestRealm offers more than just gameplay; it promotes a lifestyle of returning to nature and finding peace.
Explore Three Core Living Areas in HarvestRealm
HarvestRealm features a vibrant virtual world with three main areas: the farm, the ranch, and the fishery, each offering unique experiences and challenges.
Farm: Players start their rural journey here, growing crops like wheat, corn, and carrots. As seasons change, players learn about crop cycles and care, experiencing the entire process from planting to harvest. The farm serves as a food source and the starting point for interacting with nature.
Ranch: Players can interact with animals, adopting and caring for cows, sheep, chickens, and more. Over time, these animals grow and provide various yields and companionship, highlighting the responsibility and joy of animal care.
Fishery: This expansive water area invites players to explore and conquer. Players can learn different aquaculture techniques to breed fish, pearls, and turtles. As skills improve, they unlock more advanced aquatic creatures, enjoying the journey from shallow waters to the deep sea.
These areas are from HarvestRealm's diverse game world, each with a unique ecosystem and economic cycle. Player activities impact their progress and contribute to the game's community development.
Building a Vibrant Player Community
Social interaction is a core feature of HarvestRealm, enhancing the gaming experience and fostering a lively online community. The game encourages communication and cooperation among players, adding to the overall enjoyment.
Animal Arena: This competitive stage allows players to showcase their pets and strategies. Players can enter their well-cared-for animals in competitions, testing their knowledge and tactics. Winners earn in-game rewards and community prestige.
VIP System and Lordship: These roles provide more social interaction opportunities. VIP players enjoy exclusive events, extra rewards, and personalized services. Lords manage their territories, organize activities, and strengthen community bonds.
Resource Sharing and Trading: Players can trade farm products, animals, and aquatic items in the market, promoting economic flow and strengthening player connections.
Economic System: Currency and Value Creation
HarvestRealm's economic system is key to its ongoing appeal. The game features two main currencies: gold seeds and silver seeds.
Gold Seeds: This premium currency is earned through high-level activities and trading. Players can use gold seeds for VIP privileges, special items, and real-world rewards, rewarding long-term investment and contributions.
Silver Seeds: The basic currency earned through daily farming, breeding, and fishing. Silver seeds are used to buy seeds and animals and participate in entertainment. To maintain economic stability, a yield reduction mechanism reduces silver seed output when it reaches a certain level.
We also use insurance and prize pools to manage market fluctuations, ensuring a healthy and sustainable game economy. This design offers a rich gaming experience and a fair, orderly environment where players' efforts are reasonably rewarded.
Innovative Technology: K70 Tribe's R&D Strength and Future Layout
As the developer of HarvestRealm, K70 Tribe showcases its strong capabilities and innovative spirit in game development. Our R&D team comprises top talents in the industry, proficient in game design and deeply understanding and applying the latest technologies.
Metaverse Concept: HarvestRealm introduces the metaverse, allowing players to own land and property and experience ownership and management rights. We aim to deepen this integration and offer more immersive experiences.
AIGC Technology: This technology dynamically generates personalized game content based on player behaviour and preferences, ensuring a unique experience for each player.
IP Animation and AR Technology: These bring richer visuals and interactions. AR technology allows players to interact with game characters in the real world, overlaying virtual items onto real scenes for added fun and realism.
K70 Tribe's R&D strength and innovation lay a solid foundation for HarvestRealm's future. We will continue to invest in cutting-edge technologies to maintain the game's leading position and ongoing appeal.
Social Responsibility and Industry Contributions
K70 Tribe believes in corporate social responsibility. HarvestRealm serves as a platform to fulfil these duties.
Esports Fund: We support the industry, helping potential players and teams achieve their dreams. Through the Love Sapling Program, we participate in environmental protection, donating to relevant organizations for every certain number of in-game items sold.
Education and Cultural Promotion: Through HarvestRealm, we spread positive values like teamwork, environmental protection, and cultural diversity.
Our social responsibility efforts enhance HarvestRealm's positive image and set a good example in the gaming industry.
Future Prospects of HarvestRealm
We are excited and confident about HarvestRealm's future. Its success lies in its innovative gameplay, social experience, and deeper meaning—connecting people with nature and inspiring a love for life.
Continuous Innovation: We will keep investing in R&D, introducing new technologies, and optimizing the gaming experience to ensure content remains fresh and forward-thinking. We aim to make HarvestRealm the most desired rural life experience platform.
Leading the Industry: HarvestRealm will continue to be K70 Tribe's flagship product, leading innovation in the gaming industry and providing an excellent experience for players worldwide. Through relentless effort and innovation, HarvestRealm will open a new era of rural life, offering peace and joy to every player.

**Cryptographic Security:** Blockchain utilizes cryptographic methods to safeguard transactions and guarantee the integrity of data. Public and private keys, digital signatures, and hash functions are essential components in this procedure.
**Smart Contracts:** Smart contracts are contracts that execute themselves based on predetermined rules stored in the blockchain. They automate and uphold the conditions of contracts, removing the necessity for middlemen.
**Tokenization:** Tokens are used to denote digital assets or services within a blockchain environment. They are versatile and can serve different functions such as making payments, voting, and accessing services.
**Network Infrastructure:** The core of the blockchain network is made up of the basic network infrastructure, such as nodes, wallets, and communication protocols.
**Top technologies for developing blockchain:**
Next, we will investigate some of the top technologies and platforms available for building your own blockchain network.
**Polkadot:** Polkadot is a modern blockchain protocol that enables connectivity among various blockchains. The creative layout enables separate blockchains to securely exchange information and assets, creating opportunities for collaboration across different chains.
**Binance Smart Chain:** Binance Smart Chain is a platform for building decentralized applications and digital assets with low fees and high performance. It works with Binance Chain, enabling smooth asset transfers between the two networks.
**Hyperledger Fabric:** Created by the Linux Foundation, Hyperledger Fabric is a blockchain platform with restricted access, specifically made for business purposes. It provides modular architecture, privacy, and scalability features, making it ideal for businesses that need strict access control and governance.
**Ethereum:** Ethereum is a well-liked platform for creating decentralized applications (DApps) and smart contracts that are open-source. Its ideal for launching customized blockchain solutions due to its flexibility and large developer community.
Instructions for Building Your Own Blockchain Environment:
Having discussed the fundamental elements and technologies, next we will detail the process of setting up your blockchain network.

**Choose the Right Platform:** Choose a blockchain platform that meets your needs, taking into account aspects such as scalability, consensus mechanism, and developer backing.
**Design the Architecture:** Create the structure of your blockchain network, including the agreement process, intelligent contract reasoning, and currency system.
**Development and Testing:** Develop and test your blockchain network, ensuring it functions as intended and meets security standards.
**Deployment and Maintenance:** Install your blockchain network on the chosen infrastructure and uphold its functioning and security.
**Conclusion:**
Developing your own blockchain ecosystem can be challenging but is ultimately fulfilling. Entrepreneurs and top businessmen can fully tap into the potential of blockchain technology in their industries by utilizing advanced technologies and a structured strategy. Welcome new ideas, stay up-to-date on the latest advancements, and begin your path towards achieving success in blockchain.

Unlike Web2, where data and control are held by large corporations, Web3 aims to give users more control, privacy, and security by using decentralized networks.
### **What is a Web3 Wallet?**
[A Web3 wallet](https://metla.com/blog/web3-wallet-explained) is a digital tool that lets users interact with the new decentralized web. It does more than just store cryptocurrencies; it acts as a key to access [decentralized applications (dApps)](https://metla.com/blog/what-are-decentralized-apps), manage digital assets, and engage in [decentralized finance (DeFi)](https://metla.com/blog/what-is-decentralized-finance-defi).
With a Web3 wallet, users can securely store, send, and receive cryptocurrencies while keeping full control over their private keys and personal data. Web3 wallets are essential for navigating and participating in the growing world of the decentralized internet.
### **How Web3 Wallets Work**
Web3 wallets operate on blockchain technology, a decentralized ledger that records transactions across many computers, ensuring security and transparency. These wallets use encryption to protect your digital assets.
Each wallet generates a pair of cryptographic keys: a private key and a public key.
* **Private Key:** This is a secret, alphanumeric code that allows you to access and manage your cryptocurrencies. It must be kept confidential, as anyone with your private key can control your assets.
* **Public Key:** This is an alphanumeric code derived from a private key. It can be shared openly and is used to receive funds. When someone sends you cryptocurrency, they use your public key to direct the transaction to your wallet.
### **Web3** Wallets **vs. Traditional Wallets**
Unlike traditional digital wallets that store your data on centralized servers and rely on intermediaries (like banks), Web3 wallets give you complete control over your assets.
With Web3 wallets, you own your private keys, meaning you directly control your funds and data without needing a third party. This setup enhances security and privacy, as only you have access to your private key.
Additionally, Web3 wallets allow easy interaction with decentralized applications (dApps) and decentralized finance (DeFi) platforms, making them essential tools for using the decentralized web.
## **Types of Web3** **Wallets**
Web3 wallets come in various forms, each with unique features and levels of security. The two main categories are hardware wallets and software wallets.
* **Hardware Wallets:** These are physical devices that store your private keys offline, making them very secure. Since they are not connected to the internet, they are less likely to be hacked. Examples include Ledger Nano S, Ledger Nano X, and Trezor. They are perfect for long-term storage of large amounts of cryptocurrency.
* **Software Wallets:** These are applications or browser extensions that store your private keys online. They are more convenient for frequent transactions but can be more vulnerable to online threats. Software wallets are further divided into hot wallets and cold wallets.
* **Hot Wallets:** These wallets are always connected to the internet. They are easy to use and great for day-to-day transactions. Popular hot wallets include MetaMask, Trust Wallet, and Coinbase Wallet. However, their constant internet connection makes them more vulnerable to hacks.
* **Cold Wallets:** These wallets store your private keys offline, similar to hardware wallets. They can be software wallets that are not connected to the internet or paper wallets where keys are printed on paper. They offer higher security but are less convenient for regular use.
## **Popular** Web3 **Wallets**
* **MetaMask:** A browser extension and mobile wallet known for its ease of use with Ethereum and [ERC-20 tokens](https://metla.com/blog/erc-20-tokens-explained).
* **Trust Wallet:** A mobile wallet that supports multiple cryptocurrencies and offers a built-in dApp browser.
* **Ledger Nano X:** A popular hardware wallet known for its security features and support for numerous cryptocurrencies.
* **Coinbase Wallet:** A user-friendly mobile wallet that supports a wide range of digital assets and DeFi applications.
## **Key Features of** Web3 **Wallets**
Web3 wallets have unique features that improve security and functionality.
* **Security Features:** Web3 wallets use private keys and seed phrases to protect your assets. The private key is a unique, secret number that allows you to access and manage your cryptocurrencies. The seed phrase is a series of words generated by the wallet, used to recover your private keys if lost. Keeping these secure is crucial for maintaining control over your funds.
* **Cross-Chain Functionality:** Many Web3 wallets support multiple blockchain networks, allowing users to manage different cryptocurrencies in one wallet. This cross-chain functionality enables easy interaction with various decentralized applications (dApps) across different platforms.
* **Cryptocurrency Support:** Web3 wallets typically support a wide range of cryptocurrencies, not just one. This includes popular ones like Bitcoin and Ethereum, as well as many altcoins and tokens. This broad support allows users to diversify their digital asset portfolio and participate in a wider array of decentralized finance (DeFi) services.
## Summary
Web3 represents a decentralized, user-empowered internet phase. Web3 wallets are digital tools for interacting with the decentralized web, managing digital assets, and engaging in DeFi. They use blockchain technology, with private and public keys for securing and managing cryptocurrencies.
Types of Web3 wallets include hardware wallets (offline, secure) and software wallets (online, convenient). Popular Web3 wallets include MetaMask, Trust Wallet, Ledger Nano X, and Coinbase Wallet. Key features include security measures, cross-chain functionality, and support for multiple cryptocurrencies.
Web3 wallets are essential tools for navigating the decentralized internet, offering enhanced security, user control, and support for a wide range of digital assets. | ipratikmali |

Node JS Microservices deployment using AWS CDK
{% embed https://www.youtube.com/watch?v=nhM_HDvW5IA %}
The AWS Cloud Development Kit (CDK) is an open-source software development framework to define your cloud application resources using familiar programming languages. It allows you to define your cloud infrastructure as code and provision it through AWS CloudFormation.
## Key Features of AWS CDK:
1. **Infrastructure as Code (IaC)**: Define your AWS resources using high-level programming languages like TypeScript, JavaScript, Python, Java, and C#.
2. **Constructs**: The basic building blocks of the CDK. Constructs are cloud components that can be composed to form stacks, which represent an application or a piece of your infrastructure.
3. **Stacks**: A stack in AWS CDK is a unit of deployment. It includes one or more resources that are deployed together.
4. **Libraries and Modules**: AWS CDK provides a library of high-level constructs called the AWS Construct Library, which simplifies defining AWS resources.
5. **Cross-Environment Support**: You can deploy stacks to different AWS environments (accounts and regions).
6. **Integration with AWS Services**: Directly integrates with AWS services and supports them as first-class constructs.
7. **Code Synthesis**: CDK code is converted into AWS CloudFormation templates, which are then used for provisioning resources.
## Basic Workflow:
1. **Install AWS CDK**:
- You can install the AWS CDK using npm:
```sh
npm install -g aws-cdk
```
2. **Initialize a CDK Project**:
- Use the CDK CLI to create a new CDK project:
```sh
cdk init app --language=typescript
```
3. **Define Resources**:
- In your CDK app, define the AWS resources using constructs. For example, to define an S3 bucket in TypeScript:
```typescript
import * as cdk from '@aws-cdk/core';
import * as s3 from '@aws-cdk/aws-s3';
class MyStack extends cdk.Stack {
constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
super(scope, id, props);
new s3.Bucket(this, 'MyFirstBucket', {
versioned: true
});
}
}
const app = new cdk.App();
new MyStack(app, 'MyStack');
```
4. **Deploy the Stack**:
- Synthesize and deploy your CDK app:
```sh
cdk synth
cdk deploy
```
5. **Manage Stacks**:
- You can also destroy stacks using the CLI:
```sh
cdk destroy
```
## Benefits of Using AWS CDK:
- **Productivity**: Developers can use the same programming language for both application and infrastructure code.
- **Reusability**: Constructs and stacks can be reused across multiple projects.
- **Best Practices**: Encourages the use of AWS best practices and integrates with AWS services seamlessly.
- **Flexibility**: Allows for customization and extension using standard programming constructs.
AWS CDK is a powerful tool for developers looking to automate and streamline their cloud infrastructure management while leveraging the full capabilities of AWS services.
