1,866,205 | 🔧Top Open Source AI Web Scrapers to Fire Up Your Market Research🔥 | Web scraping, in simpler words, is to scrape data and content from websites, the data is then saved... | 26,123 | 2024-05-27T06:27:44 | https://star-history.com/blog/ai-web-scraper | programming, ai, productivity, opensource | Web scraping, in simpler words, is to scrape data and content from websites, the data is then saved in the form of XML, Excel, or SQL. On top of lead generation, competitor monitoring, market research, web scrapers can also be used to automate your data collection process.
With the help of AI web scraping tools, the limitations associated with manual or purely code-based scraping tools can be addressed: dynamic or unstructured websites can easily be handled, all without human intervention.
Here, we present a few open-source AI web scraping tools to choose from.
## Reader
[Reader](https://github.com/jina-ai/reader) is an offering by Jina AI. It can convert any URL to an LLM-friendly input when you append a simple `https://r.jina.ai/`, and you can get structured output for your agent and RAG systems at no cost.
Since its first release just this past month (April 15th, to be exact), they have served [over 18M](https://jina.ai/news/jina-reader-for-search-grounding-to-improve-factuality-of-llms/) requests from the world, and the project itself has already gained 4.5K stargazers.
Aside from scraping any URL, Jina just released another feature where you can use `https://s.jina.ai/YOUR_SEARCH_QUERY` to search from the up-to-date knowledge on the Internet. The result includes a title, LLM-friendly markdown, and a URL that attributes the source.
Together, you can construct a comprehensive solution for LLMs, agents, and RAG systems.
## LLM Scraper
[LLM Scraper](https://github.com/mishushakov/llm-scraper) is a TypeScript library that can convert any webpage into structured data using LLMs. Essentially, it uses function calling to convert pages to structured data.
Simliarly to Reader, it was open-sourced just last month. It currently supports Local (GGUF), OpenAI, Groq chat models. Apparently, the author is [working on](https://news.ycombinator.com/item?id=40100824) supporting local LLMs via llama.cpp to lower the cost of using LLMs for web scraping.
## Firecrawl
[Firecrawl](https://github.com/mendableai/firecrawl) is an API service that can convert an URL into clean, well-formatted markdown. This format is great for LLM applications, offering a structured yet flexible way to represent web content.
This tool is tailored for LLM engineers, data scientists, AI researchers, and developers looking to harness web data for training machine learning models, market research, content aggregation. It simplifies the data preparation process, allowing professionals to focus on insights and model development, and you can self-host it to your own taste.
## ScrapeGraphAI
[ScrapeGraphAI](https://github.com/VinciGit00/Scrapegraph-ai) is a Python library that uses LLM and direct graph logic to create scraping pipelines for websites and local documents (XML, HTML, JSON, etc.). With ScrapeGraphAI, you get to specify exactly what sort of data you want to extract.
ScrapegraphAI leverages the power of LLMs, and can thus adapt to changes in website structures, reducing the need for constant developer intervention. This flexibility ensures that scrapers remain functional even when website layouts change.
The LLMs it currently supports include GPT, Gemini, Groq, Azure, Hugging Face, as well as local models.
## LangChain
What is LangChain not capable of? Not [web scraping](https://python.langchain.com/v0.1/docs/use_cases/web_scraping/).
One of web scraping's biggest challenges is the changing nature of modern websites' layouts and content, which requires modifying scraping scripts to accommodate the changes, and LangChain also utilizes function (e.g., OpenAI) with an extraction chain, so that you don't have to change your code constantly when websites change.
If you are doing research and want to scrape only news article's name and summary from The Wall Street Journal website, it's got you covered.
## To Sum Up
Of course, there is no one-size-fits-all web scraper. Do you prefer old-school traditional web scrapers or LLM-empowered ones? | milasuperstar |

This issue can greatly impact fertility by making it challenging for an egg to successfully implant and develop into a pregnancy. Before opting for procedures, exploring the benefits of a well balanced diet can be highly empowering. Factors that can influence thickness include;
- Age
- imbalances
- Persistent health conditions
- Ashermans syndrome
- Hormonal birth control methods
- Low body weight
- Chronic inflammation
The positive news is that your dietary choices play a significant role, in maintaining good endometrial health. A balanced diet that promotes an endometrium includes;
- natural fats
- Antioxidants
- Whole grains
- Plant based proteins
- Foods rich, in iron
- Ensure intake of adequate folate.
- Essential amino acid supplements
Remember, consistency is vital! Building an endometrium requires time and commitment. If you don't see results don't lose heart. Improving your health is a process that demands perseverance and patience. Just like Rome wasn't built in a day your health won't transform either. Take it one step at a time. You'll create an environment for successful implantation and pregnancy.

1,865,480 | Building a Map Marker PWA with Amplify Gen 2 (Auth, Geo and CI/CD) | This is a submission for the The AWS Amplify Fullstack TypeScript Challenge What I... | 0 | 2024-05-27T06:09:46 | https://dev.to/ubinix_warun/building-a-map-marker-pwa-with-amplify-gen-2-auth-geo-and-cicd-2712 | devchallenge, awschallenge, amplify, fullstack | *This is a submission for the [The AWS Amplify Fullstack TypeScript Challenge ](https://dev.to/challenges/aws)*
## What I Built
I created a Progressive Web App (PWA) called "Map Marker" that allows users to interactively pinpoint and save locations on a map. Users can create accounts to save their markers, add custom descriptions and photos, and search for specific locations. The app is built with a focus on offline accessibility, leveraging PWA features to ensure a seamless experience even without an internet connection.
## Demo
You can experience the live version of Map Marker on Amplify Hosting:
[Map Marker (DEMO)](https://main.d1uv5gxgypvnin.amplifyapp.com)
## Journey
The development journey was an exhilarating adventure, as I ventured into the world of fullstack TypeScript with Amplify Gen 2. The code-first approach allowed me to define my backend infrastructure using TypeScript, which felt natural as a frontend developer.
```bash
# Create Vite/PWA project from template.
npm create @vite-pwa/pwa@latest amplify-vite-map-marker \
--template react-ts
```
The built-in CI/CD pipeline in Amplify Hosting streamlined deployment, automatically rebuilding and publishing my app with each push to my Github repository.
```bash
# Setup Dep. and Installation
npm create amplify@latest
npm install
# Configure AWS for local development
aws sso login
# Run Sandbox
npx ampx sandbox --profile amplify-admin
```
Amplify Geo truly stole the show, providing pre-built UI components (MapView, SearchField) and convenient APIs for handling map interactions, geocoding, and place search. It dramatically simplified the integration of map functionality into my PWA.
```bash
npm add aws-amplify @aws-amplify/geo
npm add @aws-amplify/ui-react-geo
```
Additionally, I encountered a conflict with the Marker component from @aws-amplify/ui-react-geo, preventing me from customizing its behavior as needed.
```typescript
import { MapView } from '@aws-amplify/ui-react-geo';
import '@aws-amplify/ui-react-geo/styles.css';
function App() {
...
return (
<>
...
<MapView
initialViewState={{
latitude: 37.8,
longitude: -122.4,
zoom: 14,
}}>
</MapView>
</>
);
}
```
**Connected Components and/or Feature Full**
- Vite: For a smooth development experience.
- React: For building a dynamic UI.
- TypeScript: For robust code and type safety.
- AWS Amplify Gen2:
- Auth: For user authentication.
- Geo: For map display and search.
- Hosting: For seamless deployment.
## Next Steps
As Amplify Gen 2 continues to mature, I'm eager to revisit this project and fully implement the intended features. I plan to:
- **Enhance DataStore Integration**: Leverage DataStore's full potential for real-time data synchronization and offline support once it's more stable.
- **Customize Markers**: Explore solutions to overcome the UI component conflict and create more interactive and personalized markers.
- **Add More Features**: Implement features like geofencing, enhanced user profiles, and social sharing.
## Conclusion
Even though I faced some roadblocks, building this PWA map marker app with Amplify Gen 2 was a rewarding experience. It's clear that Amplify Gen 2 has immense potential to simplify fullstack development, and I'm excited to continue exploring its capabilities as it evolves. | ubinix_warun |

Scope -- Everything we create of define in code is called namespace eg variables, functions, lists, etc. This namespace can be used or accessed in a region of code. This region is called scope of that namespace.
We have two scopes:
1. Global scope -- This is scope of top-level code(top level means it's not inside any functions). We can access it anywhere in the code, but we can't change its value inside a function. This scope is good for constant variables.
2. Local scope -- namespace inside a function has local scope. We can only access this namescape inside the function not outside of it.
Now if we use same name inside a global scope and local scope, both will create two different namespaces. If we want to access and change a global namespace inside local, we have to use-- global name_of_namespace.
Now we can use and change its value also, though doing this is not a good practice.
Other things I learned today-->
1. using _ when looping over and not using the item.
2. list1=[a,b]
list2=[1,2]
list1.expand(list2) >> list1 = [a,b,1,2]
list1 += list2 #will give same result
.append is used for adding single item
3. We should all capital letters for a variable having contact value, eg PI= 3.14. This is used as the standard reference, it won't give any error if we deviate.
4. to import multiple functions from module:
from module import f1 , f2
Programs I created:-
1. Guess the number
https://replit.com/@rohitrj332024/guess-the-number-day-8#main.py
2. Guess higher or lower followers(Instagram)
https://replit.com/@rohitrj332024/higher-lower-start-day8
----------------------------------------------------------
Personal -- I am happy that I am able to solve these problems. They are taking time, and I am also following proper procedures for solving them, like writing steps to do (breaking the problem into small parts), and making a flow chart( I make them on paper right now). I hope I will be able to build a good habit and it will help me when solving bigger projects later on.

1,866,184 | The Journey of Entrepreneurship: Navigating the Path of Innovation and Resilience | In the field of business, entrepreneurship has come out in a glowing way in a matter of innovation.... | 0 | 2024-05-27T06:20:18 | https://dev.to/techstuff/the-journey-of-entrepreneurship-navigating-the-path-of-innovation-and-resilience-4fm2 | In the field of business, entrepreneurship has come out in a glowing way in a matter of innovation. It's a journey of hard work, dedication and a fire inside the individual of turning ideas into realities. Starting with business in Silicon Valley to business growing in small localities, entrepreneurship has fostered the growth of individuals and at the same time of the nation as well.
Entrepreneurship is the quality of finding opportunities in the field where nothing has been predefined. It is the path of courage, a valley of risk and a story of accepting failures and converting it into winning success. Every entrepreneur’s life is full of challenges, having a different story of failures but a clear and fixed vision of success.
One of the most important qualities of an entrepreneur is the ability of adaptation to change. In the modern world, where technology is getting upgraded day by day, it's very necessary to keep changing with the pace. Whether it is in the field of trades, or the power of digital marketing or new inventions of technologies in IT or every new and old thing coming in the market, entrepreneurs have to keep an eye on every matter to keep updated with the ongoing trends.
Entrepreneurship not only gives success but also it shapes the path for the future. Many entrepreneurs develop a business in a sense of social development. Whether it's through sustainable practices or revolutionary ideas, they have the guts to bring change in society and continue that legacy.
However, to be an entrepreneur is not a bed of roses. It is a journey of hurdles with so many uncertainties and doubts, a lot of failures and cut throat competition with established businessmen. By facing all these challenges only a true entrepreneur takes shape. It is the phase of learning from failures, getting up and presenting to the world the best one can.
Moreover, entrepreneurship is the way of innovation and creation. Whether through mentorship programs, events or co-working spaces entrepreneurs benefit each other by sharing their experience of work. By building groups of entrepreneurs having the same interest, it globally leads to development of the country.
In recent years, the growth in digital marketing has also helped entrepreneurs to reach the market very easily. Starting from getting education from online courses to selling business from a small room, everything has become reachable. Today, one just needs a device and internet to start his entrepreneurial journey.
On the verge of being an entrepreneur one should not become over-confident after getting success. After all it is the path of innovation and resilience. Every entrepreneur should share their story of success as well as failures to motivate others.
I want to conclude my blog by saying that entrepreneurship is the fight with oneself. It is the way of turning dreams into reality. Let’s navigate the path of entrepreneurship and make our life worth for the betterment of society.

####HTTPS####
While [HTTPS](https://en.wikipedia.org/wiki/HTTPS) encrypts communication between your app and the server, it relies on certificates issued by trusted authorities to verify the server's identity. Without additional security measures, the app might accept a fraudulent certificate presented by a Man-in-the-Middle [MITM](https://en.wikipedia.org/wiki/Man-in-the-middle_attack) attacker. This attacker could then intercept and decrypt sensitive data like login credentials or financial information.
<Image MITM>
Regular HTTPS relies on trusting external authorities to verify a server's identity. SSL pinning adds an extra layer of security by checking if the server's certificate matches a "fingerprint" stored directly in your app. If they don't match, the app can block the connection, preventing imposters from eavesdropping on your communication.
> **SSL certificates, like passports, expire to maintain security. Even though your app itself might not change, updating the app with the new certificate ensures a secure connection.**
Manual Implementation using `http` package
**You'll need to:**
* Load the trusted certificate (usually in PEM format) from your assets.
* Configure the SecurityContext to trust only the loaded certificate(s).
* Use the SecurityContext with your HTTP client (e.g., HttpClient) to make secure connections.
**1. Add `ssl_certificate.pem` into `pubspec.yaml`**
```dart
# The following section is specific to Flutter packages.
flutter:
# The following line ensures that the Material Icons font is
# included with your application, so that you can use the icons in
# the material Icons class.
uses-material-design: true
assets:
- assets/ssl_certificate.pem
- assets/app-logo.png
```
**2. Create Future to Load Certificate**
```dart
Future<SecurityContext> get sslClient async {
final sslCert = await rootBundle.load('assets/ssl_certificate.pem');
SecurityContext securityContext = SecurityContext(withTrustedRoots: false);
securityContext.setTrustedCertificatesBytes(sslCert.buffer.asInt8List());
HttpClient client = HttpClient(context: securityContext);
client.badCertificateCallback =
(X509Certificate cert, String host, int port) => false;
IOClient ioClient = IOClient(client);
return ioClient;
}
```
Here enabling SSL pinning by loading a trusted certificate from the app's assets and configuring the `SecurityContext` to only trust that specific certificate. This provides an extra layer of security for network connections by preventing man-in-the-middle attacks with fraudulent certificates.
**Important points to consider:**
* Make sure the certificate file in your assets is valid and belongs to the server you want to connect to securely.
* Updating the app might be necessary if the server's certificate changes and needs to be replaced in the assets.
**Testing SSL Pinning**
* **Valid Certificate** ✅
Your app will be able to establish a secure connection with the server.
* **Invalid Certificate** ⚠️
Using an invalid or expired certificate poses a security risk. Your app won't be able to establish a secure connection with the server, potentially exposing sensitive data to eavesdroppers.
You might encounter exceptions like `HandshakeException` or `CertificateNotFoundException` in such scenarios.
By following the implementation steps you can effectively bolster the communication channel between your app and its backend servers.
>**Remember, SSL pinning is just one piece of the security puzzle.**
Always adhere to secure coding practices and stay updated on the latest security threats to maintain a robust defense for your Flutter app.
**Happy Coding!** 🧑🏻💻

I recently read the post [We’ve Got Container Queries Now, But Are We Actually Using Them?](https://dev.to/1marc/weve-got-container-queries-now-but-are-we-actually-using-them-21a8-temp-slug-6054188) over at Frontend Masters Boost, and I realized that it would probably be helpful for me to document real world uses for container queries.
Today’s example: A Pagination Component.
We recently rewrote pagination at work, and I decided this is an excellent use for container queries. The pagination component has 2 modes: “Big” mode and “Little” mode which really only care about how much horizontal space they have. In most applications this can be done with media queries as your pagination is a top level thing, but we have a lot of content that gets paginated inside of modals, which may or may not take up the full screen.
Our “Big” mode is when you have multiple page links (think like 10+) and you want to have the pattern display each page link. We use a list of links and also need a “previous” and “next” button at the end. The “Little” mode is what you might think of as “mobile mode” where rather than a list of links, we use a form that has a drop down with the page options. This isn’t just for mobile but can also be used for small paginated lists.
## CSS Example
```
.pagination-container {
/* create a pagination container based on the inline size*/
container: pagination / inline-size;
/* apply some good styling */
display: flex;
justify-content: center;
align-items: center;
gap: 1ch;
font-size: 1.4rem;
border: 2px solid hotpink;
}
.page-links {
/* hide "Big" mode by default */
display: none;
list-style: none;
gap: 1ch;
margin: 0;
padding: 0;
/* when it is wider than 30ch, display it*/
@container pagination (min-width: 30ch) {
display: flex;
}
}
.page-form {
/* display "Little" mode by default */
display: flex;
flex-flow: row wrap;
justify-content: center;
align-items: center;
/* Hide it when it reached 30ch wide */
@container pagination (min-width: 30ch) {
display: none;
}
}
```

Great design combined with smart development can turn visitors into loyal users, highlighting the critical role design and development play in creating engaging and effective digital experiences.
Front-end development is the crucial link that brings intelligent design ideas to life. It's the process where creative concepts are transformed into interactive, user-friendly websites and web applications that people can see and use. [Hiring front-end developers](https://www.capitalnumbers.com/front-end-development.php?utm_source=Dev&utm_medium=cngblog&utm_id=gp0524devto) who excel in this area is essential for achieving these results.
In this blog, we will explore how front-end development and intelligent design work together to create powerful digital experiences.
## **Understanding Intelligent Design**
Intelligent design in web application development means creating websites that are smart, user-friendly, and effective. It’s about making sure the design is focused on the users, looks great, and works well. A well-thought-out design considers what users need and how they interact with the site and ensures everything functions smoothly.
**Principles of Intelligent Design:**
- **User Experience (UX) Considerations**: This means designing with the user in mind. It involves understanding what users want and need, making sure the site is easy to use, and ensuring that users have a positive experience from start to finish.
- **Visual Hierarchy and Layout**: This principle involves organizing content in a way that guides users' eyes to the most important information first. Good visual hierarchy makes it easy for users to find what they are looking for without getting overwhelmed.
- **Accessibility and Inclusivity**: Intelligent design ensures that websites are usable by everyone, including people with disabilities. This includes adding features like text descriptions for images (Alt text), ensuring good color contrast, and making the site navigable by keyboard.
- **Performance Optimization**: A well-designed site should load quickly and perform well on all devices. This means optimizing images, minimizing heavy scripts, and ensuring the site runs smoothly, even on slower internet connections.
## **Importance of Intelligent Design**
Intelligent design is crucial for successful web development because it directly impacts how users interact with a site. A well-designed website can attract and retain users, making them more likely to return and recommend the site to others. It ensures that users can easily find what they need, have a positive experience, and trust the brand or service. In short, intelligent design is key to creating effective, enjoyable, and successful digital experiences.
## **The Role of Front-End Development**
Front-end development is all about creating the parts of a website or web application that users see and interact with. It involves using several technologies:
- **HTML (HyperText Markup Language)**: This is the backbone of any web page, used to create the structure and content, like headings, paragraphs, and images.
- **CSS (Cascading Style Sheets)**: This is used to style the HTML content, controlling the layout, colors, fonts, and overall visual appearance.
- **JavaScript**: This adds interactivity to web pages, enabling features like dropdown menus, sliders, and dynamic content updates without reloading the page.
- **Frameworks and Libraries**: Tools like React, Angular, and Vue.js make it easier to build complex user interfaces by providing reusable components and structures.
**Bridging the Gap Between Design and Functionality**
Front-end developers take design prototypes created by designers and turn them into fully functional websites and web applications. These prototypes are usually visual representations of what the final product should look like. Front-end developers write the code that brings these designs to life, ensuring they work well and look good on different devices and screen sizes.
**Key Responsibilities of Front-End Developers:**
- **Implementing Responsive Design**: Ensuring that the website looks and works well on all devices, from desktop computers to smartphones. This involves using flexible layouts, images, and CSS media queries.
- **Ensuring Cross-Browser Compatibility**: Ensure the website functions correctly on all major web browsers (like Chrome, Firefox, Safari, and Edge), even though each browser may interpret code slightly differently.
- **Optimizing for Performance and Speed**: Writing efficient code ensures the website loads quickly and runs smoothly. This can involve minimizing file sizes, using efficient coding practices, and optimizing images and other assets.
- **Enhancing User Interactivity**: Adding features that make the website interactive and engaging. This can include forms, animations, and dynamic content updates that respond to user actions in real-time.
## **Tools and Technologies**
**Popular Front-End Technologies:**
- **HTML5 and CSS3:** These are the fundamental building blocks of web development. HTML5 is used to create the structure of a webpage, like headings, paragraphs, and images. CSS3 is used to style the webpage, controlling the layout, colors, fonts, and overall look and feel.
- **JavaScript:** This is the programming language that makes web pages interactive. With JavaScript, you can create dynamic elements like slideshows, forms that validate user input, and content that updates without needing to refresh the page.
- **Frameworks and Libraries:** These are tools that make it easier to work with JavaScript:
1. **React**: A library for building user interfaces, especially single-page applications where content dynamically updates without reloading the page.
2. **Angular**: A full-fledged framework for building complex web applications, providing tools for everything from handling data to creating animations.
3. **Vue.js**: A flexible framework that helps build user interfaces and single-page applications with a gentle learning curve.
**Design Tools and Prototyping**:
- **Figma, Sketch, Adobe XD**: These are popular tools designers use to create and share design prototypes. They help designers collaborate and create mockups that show what the final product should look like.
- **Integration with Front-End Workflows:** These design tools allow designers and developers to work together smoothly. Designers can share their prototypes with developers, who then use these prototypes as blueprints to build the actual website or application. These tools often provide code snippets or assets that developers can directly use, making the transition from design to development seamless.
**Development Tools:**
- **Code Editors:**
1. **VS Code (Visual Studio Code):** A powerful, free code editor that supports many programming languages and comes with features like debugging, syntax highlighting, and extensions to enhance productivity.
2. **Sublime Text:** This is another popular code editor known for its speed and simplicity. It has many features to help write and manage code efficiently.
- **Version Control:**
1. **Git**: A system for tracking changes in your code. It allows multiple developers to work on the same project simultaneously without overwriting each other's changes. Git keeps a history of changes, so you can revert to previous versions if something goes wrong.
- **Package Managers:**
1. **npm (Node Package Manager):** A tool that helps manage and install JavaScript packages and dependencies. It makes it easy to include and manage third-party libraries and tools in your projects.
2. **Yarn:** Yarn is another package manager similar to npm, known for its speed and reliability. It helps manage project dependencies and ensures consistent installations across different environments.
## **Best Practices in Front-End Development**
**Writing Clean and Maintainable Code:**
- **Commenting and Documentation:** When writing code, it's helpful to add comments that explain what the code does. This makes it easier for others (or yourself in the future) to understand how your code works. Documentation is like a manual for your code, detailing how different parts work and how to use them.
- **Modular Coding Practices:** Breaking your code into small, reusable pieces called modules makes it easier to manage and maintain. Each module should do one thing well, simplifying debugging and updating your code.
**Responsive and Mobile-First Design:**
- **Techniques for Creating Layouts that Adapt to Different Screen Sizes**: Websites should look good on all devices, from large desktop monitors to small smartphones. This involves using flexible grids, images, and CSS media queries to create layouts that adjust to different screen sizes. Mobile-first design means starting with the mobile version of your site and then expanding it to larger screens.
**Performance Optimization:**
- **Lazy Loading:** This technique delays the loading of images and other resources until they are needed. For example, images below the fold (the part of the page you have to scroll to see) won't load until the user scrolls down to them. This speeds up your site's initial load time.
- **Code Splitting:** Breaking your JavaScript code into smaller chunks that load only when needed can make your site faster. Instead of loading one large file, you load only the necessary parts as the user navigates the site.
- **Minification and Compression:** Minification removes unnecessary characters from your code (like spaces and comments) to make it smaller and faster to download. Compression reduces the size of your files further, speeding up the transfer from the server to the user's browser.
**Accessibility Considerations:**
- **ARIA Roles:** ARIA ([Accessible Rich Internet Applications](https://www.w3.org/WAI/standards-guidelines/aria/)) roles provide additional information to assistive technologies (like screen readers). They help users with disabilities navigate and understand your site better by defining roles for different parts of your web content (e.g., marking an element as a button or a navigation region).
- **Keyboard Navigation:** It is crucial for users who cannot use a mouse to ensure that all interactive elements on your site (like links, buttons, and forms) can be accessed and used with a keyboard. This involves setting proper focus states and using HTML elements that support keyboard interactions.
- **Color Contrast and Text Size**: Good color contrast makes the text readable against its background, especially for visually impaired users. The text size should be large enough to read easily and adjustable by the user. Ensuring sufficient contrast and appropriate text size improves the readability and accessibility of your content for all users.
## **Challenges and Solutions**
**Common Challenges in Front-End Development:**
- **Keeping Up with Rapidly Evolving Technologies**: The world of front-end development is always changing, with new tools, frameworks, and best practices emerging regularly. Staying current with these changes can be challenging.
- **Managing Cross-Team Collaboration**: Front-end developers often work with designers, back-end developers, and other team members. Coordinating with everyone to ensure smooth progress can be difficult, especially when everyone has different priorities and workflows.
**- Ensuring Design Fidelity:** It can be challenging to ensure that the final product looks and works exactly as the designer intended. Sometimes, the design might need to be adjusted due to technical limitations or different screen sizes.
**Solutions and Strategies:**
- **Continuous Learning and Professional Development**: To keep up with new technologies, it’s important to learn and improve your skills continuously. This can involve reading articles, taking online courses, attending workshops, and participating in developer communities. Setting aside regular time for learning can help you stay ahead.
- **Effective Communication and Project Management Tools**: Good communication is key to successful collaboration. Project management tools like Trello, Asana, or Jira can help keep everyone on the same page. Regular meetings, clear documentation, and open communication channels (like Slack or Microsoft Teams) can also improve collaboration.
- **Using Design Systems and Style Guides**: Design systems and style guides provide a set of standards for design and code, ensuring consistency across the project. These tools help bridge the gap between designers and developers by providing a common language and expectations. They include color palettes, typography, component libraries, and coding conventions.
## **Future Trends**
**Emerging Technologies in Front-End Development:**
- **Progressive Web Apps (PWAs)**: PWAs are web applications that behave like native mobile apps. They can work offline, send push notifications, and be installed on a user's home screen. PWAs combine the best of web and mobile apps, offering fast, reliable, and engaging experiences.
- **WebAssembly**: WebAssembly is a new type of code that can run in web browsers at near-native speed. It allows developers to write code in languages like C, C++, and Rust and run it on the web. This opens up possibilities for running high-performance applications, such as games and graphics editors, directly in the browser.
- **Headless CMS**: A [Headless CMS](https://medium.com/@sanjays_8381/how-headless-cms-is-changing-front-end-development-in-2024-421c6d14dd3a) (Content Management System) provides a way to manage content without being tied to a specific front-end. Instead of delivering content through predefined templates, a Headless CMS delivers content via APIs, allowing developers to build custom front-ends using any technology. This offers more flexibility and better performance.
**Evolving Design Trends:**
- **Minimalistic Design:** This trend focuses on simplicity and clarity. Minimalistic design uses white space, simple color schemes, and clean typography to create a sleek and easy-to-navigate user experience. It's about doing more with less, removing unnecessary elements to let the content shine.
- **Dark Mode**: Dark mode is becoming increasingly popular. It uses dark backgrounds with light text, reducing eye strain and saving battery life on OLED screens. Many users prefer dark mode for its modern look and the comfort it provides in low-light environments.
-** Motion UI**: Motion UI uses animations and transitions to enhance user experience. This can include animated elements that guide users through a process, subtle hover effects, and transitions that make interactions feel more fluid. Motion UI helps make websites feel more dynamic and engaging, improving the user experience.

## What We Built
Many businesses often require a solution to notify customers about the tracking status of their packages (i.e. whether the package has arrived, where the package is in transit, and how long until the package arrives). We offer an easy-to-use web app that allows users to query information about tracking numbers and get the data they need in a single place. This is useful for some businesses that may not have an automated system in place to send tracking status to their customers, but want a quick and easy way to check the tracking status of their customers' packages in one place. This can also be used by customers to check their package tracking status as well. To use the app, you ask the chatbot information about your tracking number, and it'll respond back with relevant information about the tracking status.
## Demo
<!-- Share a link to your deployed solution on Amplify Hosting, and include some screenshots here. -->

Check out the [code here](https://github.com/ImgyeongLee/TrackNChat)!
## Journey
Our team consisted of 2 members, and we spent a single day working on the project (actually on the same day the project was to be turned in for the hackathon) from the idea to submission. It was a fun sprint to see how much we could get done in a short time and to learn/try new technologies we hadn't used before. We used AWS Amplify to power our full-stack application and AWS Lex to power the chatbot. While working on our project, we discovered how easy it was to follow the Amplify docs to get started and incorporate all their components including frontend, backend, hosting, data storage, and automated CI/CD. In regards to the chatbot, at first we considered developing a custom AI agent/tool, but realized that it would take too much time, and so in our search for something simpler, we came across AWS Lex which already had documenation on how to connect it with AWS Amplify. We found that using AWS Lex worked surprisingly well, and we could ask the chatbot in human language, and it'd be able to understand our intent and parse out the tracking number from the query. We weren't able to accomplish all the things that we'd like to implement, but we were proud that we got a chance to learn new technologies and build a fun and useful tool.
These are some of the things we'd like to incorporate into our app in the future:
- Interact with the UPS, USPS, FedEx, DHL, etc. APIs to could get direct access to the tracking information rather than using an NPM package that provides basic details on a tracking number. We would've implemented this, but we found out that when we signed up for the USPS API, they require an approval process that we simply didn't have time to wait for.
- Allow uploading of CSVs/Excel files in bulk to process many tracking numbers and the chatbot would provide the status of all tracking numbers
**Connected Components and/or Feature Full**
<!-- Let us know if you developed UI using Amplify connected components for UX patterns, and/or if your project includes all four features: data, authentication, serverless functions, and file storage. -->
This is an architecture of how our system works.
When an user interacts with our NextJS web app, they can ask information about their tracking number, and it'll send a request to AWS Lex which forwards the request to AWS Lambda which can make a request to the shipping provider APIs to provide information on the tracking number. It turns out AWS Lex works very similar to Amazon Alexa and you can optionally add in generative AI support with AWS Bedrock for even better customer interaction.
> AWS Lex chatbot configuration
> AWS Lambda handler to process chatbot events that match the QueryTracking intent
```typescript
export const handler: Handler = async (event, context) => {
console.log(JSON.stringify(event, null, 2));
const sessionState = event.sessionState;
sessionState.intent.state = 'Fulfilled';
sessionState.dialogAction = {
type: 'Close'
};
const trackingNumber =
event.interpretations[0].intent.slots.TrackingNumber.value
.interpretedValue;
const tracking = getTracking(trackingNumber); // <-- returns tracking details in this object
return {
sessionState,
messages: [
{
contentType: 'PlainText',
content: JSON.stringify(tracking)
}
]
};
}
```
> NextJS interaction with chatbot (triggered every time user enters a chat message)
```typescript
async function submitMsg(userInput: string) {
await Interactions.send({
botName,
message: userInput
});
}
```
> NextJS callback for chatbot responses
```typescript
Interactions.onComplete({
botName,
callback: async (error?: Error, response?: {[key: string]: any}) => {
if (error) {
alert('bot conversation failed');
} else if (response) {
// <process chatbot response here (e.g. display to user)>
}
}
});
```
All users are assigned a guest user id, provided by the AWS Cognito service. We use this id to store chat sessions and all the chat content so that users can refer back to their previous chat histories. Users can also optionally sign in to save their chat sessions to their accounts instead. This is similar to ChatGPT's website where you can view all your chat history. The data is read from/written to DynamoDB via AppSync GraphQL. And all of this is abstracted with the AWS Amplify typescript SDK!
> Authentication component
```typescript
<Authenticator>
{({ signOut, user }) => (
<main>
<h1>Hello {user?.username}</h1>
<button onClick={signOut}>Sign out</button>
</main>
)}
</Authenticator>
```
> Data schema
```typescript
const schema = a.schema({
ChatSession: a
.model({
userId: a.string().required(),
chatContents: a.hasMany('ChatContent', 'chatSessionId')
})
.authorization((allow) => [allow.publicApiKey()]),
ChatContent: a
.model({
content: a.string().required(),
source: a.enum(['USER', 'BOT']),
chatSessionId: a.id().required(),
chatSession: a.belongsTo('ChatSession', 'chatSessionId')
})
.authorization((allow) => [allow.publicApiKey()])
});
```
One of the issues we currently still encounter is when we create a new ChatSession record in the database and try to get the data back with a query like this.
> GraphQL query
```graphql
query MyQuery {
getChatContent(id: "8f525820-8132-42ca-82e6-fa49116d3e2b") {
id
content
chatSessionId
}
listChatContents(
filter: {chatSessionId: {eq: "b56b034e-3cb5-479b-92fa-cebe1bd74e9c"}}
) {
items {
id
content
}
}
}
```
The data returned ends up being like this. For some reason `listChatContents` is empty even though it should contain the same data as `getChatContent`. If anyone has an answer to this problem, please let us know in the comments.
> JSON output
```json
{
"data": {
"getChatContent": {
"id": "8f525820-8132-42ca-82e6-fa49116d3e2b",
"content": "Some content",
"chatSessionId": "b56b034e-3cb5-479b-92fa-cebe1bd74e9c"
},
"listChatContents": {
"items": []
}
}
}
```
Continuing on, the NextJS app is styled with tailwindss and shadcn, and it is hosted on AWS Amplify. Every time we push new code changes to our GitHub repo, AWS Amplify will automatically build and deploy the new version of our app to the live site.
## Conclusion
And, that wraps up our project. We had a lot of fun working on this project and participating in this hackathon. It gave us a chance to apply our skills as well as explore the new AWS Amplify gen 2 platform and other AWS services as well.

1,866,175 | 吉田安昌（Ansyou Yoshida）：加速するインフレ時代への突入 | 2023年は日本が全面的に好転する年です。 経済から社会まで、日本はその失われた30年の影から全面的に抜け出しています。... | 0 | 2024-05-27T05:52:38 | https://dev.to/ansiyou/ji-tian-an-chang-ansyou-yoshidajia-su-suruinhureshi-dai-henotu-ru-3coh | 2023年は日本が全面的に好転する年です。 経済から社会まで、日本はその失われた30年の影から全面的に抜け出しています。 世界経済が腐るほどある時代にあって、日本の表現は少しだけ輝いています。
2024年、日本は昨年の勢いを持続する可能性が高い。以下の動きは、特に強く感じられます。
一、25年間のデフレが終わる
2023年の世界経済を一言で表現すれば、それは「停滞」です。ヨーロッパでも、アメリカでも、アジアの新興国でも、停滞感があります。 日本の経済だけがまだ光明が見えています。
2024年は、日本経済が「飛躍」する年になると予想されています。 景気回復が続き、インフレ時代が到来します。 2023年12月21日に閣議決定された見通しによると、2024年度の日本のGDPは物価変動を除いた実質で約1.3％成長し、今年7月の見通しより0.1ポイント上昇します。
日本政府は来年も国内消費と投資の両方が堅調に推移することを期待しています。そして日本政府は昨年11月、低所得家庭への補助金の支給や住民税の減税など、総額約17兆円の総合的な景気刺激策を決定し、個人消費は1.2％、企業所得はより満足のいくものとなり、設備投資は3.3％の成長が見込まれるなど、所得環境の改善を促進することが期待されています。 この活気あふれる光景は、まるで40年前に戻ったかのようす。
2023年、日本の物価は上昇しています。1月のコアインフレ率は4.2%と40年ぶりの高水準に達しました。 10月まで、コアインフレ指数は19ヶ月連続で2％を超えています。 そして、来年、2024年の日本の消費者物価総合指数は、需要の増加により約2.5％に達すると政府は予測しています。
日本内閣府は2023年版の経済財政白書に、日本経済は25年間続いたデフレとの戦いの転換点を迎えていると書いていました。
同時に、日本は徐々に「預金金利」の国になり始めました。11月1日には、三菱東京UFJ銀行が円定期預金の金利を変更すると発表し、銀行業界は騒然となりました。 11月6日以降、定期預金の年利は5年物で0.002％から0.07％、10年物で0.2％と100倍に引き上げられました。 他の銀行もこれに追随し始めました。
預金金利の引き上げは、市場にシグナルが出ました: 日本はすでにデフレから脱却し、金利を引き上げようとしています。
二、給料が上がる！
2023年、日本の所得はインフレ率に追いつくことができなかった。 そのため、岸田文雄首相は2023年末に、「来年」は賃金上昇が物価上昇を上回ることが間違いなく実現すると公言しました。
一つ目は、経済成長に牽引され、企業が賃金を上げるより強い立場にあるからです。
二つ目は、日本の労働力不足が来年も続くからです。 2023年11月、日本の完全失業率はわずか2.5%で、全国で3件の求人に対して約2.3人しか採用していませんでした。日本企業は人材を確保を、維持するために賃上げを実施すると予想されます。
日本政府は来年度の賃上げ率が2.5%に達すると予想しています。 政府の景気刺激策の影響も加えれば、所得の伸び率は3.8%に達し、予想物価上昇率（2.5%）を上回ります。
賃金が物価上昇率を上回ることで、健全な循環が形成され、経済が上向きに発展します。 日本のインフレの時代が来ました。
三、円高反動
2024年、日本は世界で最後のマイナス金利体系を脱退する国となり、世界の他の主要中央銀行（米国、英国、欧州など）が一斉に利下げに踏み切ることも相まって、円は上昇に転じようとしています。
国際的には、FRBが利上げを停止し、日米金利差が縮小することで、円高が進みやすくなります。国内的には、日本がデフレから脱却し、マイナス金利が解除され、円の購買力が再構築されます。
2023年末の最終金利決定会合では、パウエル議長が再び利上げ中止を表明し、利下げ議論の開始を緩やかに認めました。 市場予測によると、米国は来年少なくとも2～3回の利下げを行う可能性が高いです：連邦基準金利は現在の5.25～5.5％から4.5～4.75％に引き下げられます。
最も楽観的な予想では、FRBは早ければ来年3月にも25ベーシスポイントの利下げに踏み切る可能性があり、年内に100ベーシスポイント以上の利下げが実施される確率は85％以上となります。
日本中央銀行は、2023年1年間マイナス金利政策を維持しましたが、年内に3回ycc政策を調整し、10年期の日本国債利回りを引き上げ、2024年第1四半期（1-3月）に国債買い入れ規模の縮小を発表し、国債買い入れ圧力を鈍化させましたが、この動きも日銀が金融正常化への道を開く可能性があると見られています。
現在のところ、4月は日本中央銀行がマイナス金利を脱退する可能性が最も高いタイミングであり、3月中旬の春の給与交渉結果を待って、2024年の日本の賃上げの動きを判断してから行動することになります。一部の観点では、日本中央銀行は1月に基準金利の引き上げを検討し、マイナス金利を終了させる可能性があります。FRBの利下げサイクルが始まる前に行動を起こすことで、将来の金融政策調整の柔軟性を確保します。
2023年11月、ドル円相場は1ドル＝151.5～151.9円のレンジまで下げましたが、市場が来年の日米通貨シフトに賭けているため、12月までに円相場は7％上昇し、140円台まで戻りました。 大手証券会社数社の組み合わせでは、2024年末の円相場は120～125円台から130円台になると予想しています。
言い換えれば、来年は円高が10～15％程度の余剰があると予想されています。
円高が進むと、資本の利潤追求体質から、これまで海外に投資していた資金がスプレッドの縮小により日本への回帰を加速させ、円ロングは2024年のアジアで最も人気のある取引のひとつになるかもしれません。
四、住宅価格の高騰が続きます
2023年、東京の新築住宅価格は年率50％近く上昇し、日本の不動産市場の底打ちを確認しました。2024年、日銀の利上げと円高が予測される状況では、日本の住宅価格は上昇を続けます。
過去1、2年間、急激な円安で日本の不動産市場に資産熱の波が押し寄せましたが、今後、しばらくの間は、日本の不動産が好まれる。主な理由は日本経済への強気です。
2024年、1つは世界経済の成長率が減速し、資本が流れる場所が少なくなり、日本の不動産がまだ潜在力の高い投資対象であること；２つ目は、日本がデフレから脱却し始めたことで、日本人自身も、資産配分を行わなければ資産が「縮小」する可能性が高く、収益を生むキャッシュフローが現金預金よりも良いことに気づき始めたかもしれないことです。
さらに、来年、日本銀行は金利を引き上げるが、決して高金利、世界と比較して、日本の金融環境はまだ緩やかです。世界的な低金利投資不況という日本の属性は変わっていません。日本の不動産価格は、例年のように高騰する可能性は低いかもしれないが、着実にステップアップしていきます。
2024年には、日本の不動産をめぐる動向もこれまでとは異なります：
1、国内外の富裕層がマンション一棟に投資する傾向が強まり、コアエリアの一棟物件は更に人気があります。
2、円安で新築住宅の供給が、購買力の一部に割かれる以前は、円高で日本の住宅価格が右肩上がりに上昇するため、中古住宅市場（日本の不動産取引における主な投資対象）に資金が集中し、新築マンションよりも中古マンションが求められるようになります。
3、国内の不動産競争で、東京はアジア金融の中心的存在の栄光を取り戻すことを目指しています。東京VS東京以外の日本の不動産部門はより深刻になります。 | ansiyou | |

1,866,171 | How To Know If What You Are Experiencing Is A Dental Emergency Or Not | Like other diseases, dental care is equally important as it causes severe pain, and can be harmful if... | 0 | 2024-05-27T05:47:36 | https://dev.to/mulgrave_dental_c158e48bd/how-to-know-if-what-you-are-experiencing-is-a-dental-emergency-or-not-4hc0 | dentist, dentistinsutton, emergencydental | Like other diseases, dental care is equally important as it causes severe pain, and can be harmful if ignored for long. You must know [dental emergency](belmontdentalcare.co.uk) symptoms so that you can contact your dentist and get the issue resolved on time. There are a range of symptoms are there which you must know about dental emergencies and visit a dental professional on time.
Signs of A Dental Emergency:
There are a range of symptoms are there which you must have clear knowledge about to know when it is time to visit a doctor. Some of the common symptoms which you must include are tooth pain, broken or sliced tooth, swelling, bleeding, lost crown after treatment, bleeding though various other reasons to tongue and lips and inner chicks, and persistent bad breath can be a symptom.
High pain
High pain indicates that there is something wrong with your tooth which is unfavourable, and as the pain increases it shows a clear sign that you must now rush to a dental professional. Some of the common causes of pain include,
Tooth infection: Infections caused by bacteria when they enter the inner part of the teeth lead to sharp pain and can radiate from tooth to ears and neck. Cavities or removal of the protective layer of the tooth can be a reason for this.
Tooth fracture: Tooth fracture is a situation where the inner layer of the tooth i.e. dentin, pulp and tooth roots are exposed, then it leads to sharp pain and it worsens with too hot and cold food.
Gum disease: Some gum diseases and pocket formation around the tooth cause severe pain, which gest worsen with bacterial infection.
Impacted wisdom tooth: If an emerging tooth is stuck and unable to emerge fully, then it causes paint and radiate to surrounding teeth and jaw. It even causes swelling and infection.
Dental trauma: Any sort of shock or impact due to injury that leads to knocked-out teeth, fracture or crack leading to pain.
Bleeding that does not stop
You need dental emergency treatment if you unstopped bleeding. Some of the common causes include.
Trauma: Injury and falling cause shock and impact teeth. Cuts in the mouth can lead to bleeding.
Gum Disease: Some diseases such as periodontitis cause gums to inflame and cause them to bleed. It may include pain.
Tooth extraction: If the bleeding persists even after applying pressure on the area, and even a few hours after tooth extraction can be a sign of a complex situation such as a dry socket and inability to clot the blood and needs attention.
Oral surgery: Bleeding after oral surgery is not common and needs attention it could be a sign of lack of clot, and needs dental attention.
Loose or broken teeth
Tooth decay: Tooth cavities can weaken the teeth which lose them or break them, and it could lead to bleeding or infection that needs immediate attention.
Gum diseases: With various gum diseases supporting mass and bones get lost and this causes the teeth to lose and change their positions, and this needs immediate attention.
Bruxism: excessive grinding and pressure on the tooth while sleeping over time makes the teeth get loose and it can even have fractures, and this needs attention to prevent further damage.
Previous dental work: It may happen that, the previously fixed tooth is dislocated or lost due to failure of previous dental treatments.
Swollen Face with Pain
Abscess: Due to bacterial attack, there is the formation of pockets filled with liquid and pus and they are mainly formed near gum lines, and this can be worsened with a swollen face, so seek immediate attention.
Infection: Some infections in specific regions such as periodontal areas lead to swollen faces, and they can spread and lead to severe pain, and thus visiting a dental professional is a must, it can even cause fever. It is recommended to visit nearby [emergency Dental Care Care Sutton](https://www.mulgravedental.com/emergency-dental-care-sutton/).
Gum diseases: Swelling near gum lines and infection can cause tooth loss and severe pain that radiates to the face. The nearby bone of the gum can be damaged, and thus attention is required by the dentist.
Difficulty breathing or swallowing
Infection: Many people face issues of difficulty in breathing and swallowing, there are various reasons for this such as infection spreading to the nose and throat and blocking air passage and filling fluids that lead to breathing issues.
Accidents and trauma: Swelling of gums may spread through the neck, block air passage and lead to breathing difficulty. Accidents and trauma can cause breathing issues due to shock, swallowing, and misalignment of the structure of the neck and shoulder.
Allergy: Some patients are rarely allergic to filling materials, and chemicals used for treatment or anaesthesia which leads to swelling of the throat and blocking air passage.
Food Stuck Between Teeth and Gums
Pain and discomfort: When a given piece of food gets stuck tightly between teeth it irritates and even leads to inflammation and pain. Over the long term, it could lead to cavity formation and leads to swelling and pain.
Gum infection: Food particles near gums and teeth create the perfect environment for bacteria to thrive and lead to infections such as gingivitis and more. It could lead to swelling, redness, pus and more.
Tooth decay: Food particles stuck invite bacteria to feed on sugar and carbohydrates, and release acidic waste they cause enamel to erode and thus expose tooth roots that need immediate attention.
Abscess formation: Sometimes food stuck causes the formation of fluid-filled pockets and pus formation that is very painful and needs immediate attention, or can worsen the situation.
Conclusion
You must be aware of dental emergencies and all possible symptoms and causes that lead to them, to be aware and take immediate action if you find any of such symptoms. If you are facing high pain, bleeding, breathing issues, shock and trauma, food stuck or proper brushing leads to the formation of pus pockets, pain, etc. which needs to be attended to immediately by dental professionals.

1,866,170 | Enhancing Construction Efficiency: The Power of Collaboration between Architects, Contractors, and Lumber Takeoff | Streamlining Design and Planning Processes Successful projects in the construction industry rely... | 0 | 2024-05-27T05:47:29 | https://dev.to/piterson_max_032d21d48ff7/enhancing-construction-efficiency-the-power-of-collaboration-between-architects-contractors-and-lumber-takeoff-4ie0 | lumber, estimator, takeoff, services | Streamlining Design and Planning Processes
Successful projects in the construction industry rely heavily on the close cooperation between architects, contractors and [lumber takeoff service](https://lumberestimator.us/).Everyone involved is essential to the success of a project because they help ensure the vision of the project is accurate and efficient from conception to completion. In this section, we explore the benefits of these important actors working together and how this encourages cost savings, innovation and planning in construction.
The creative visionaries driving a construction endeavor are architects. Drawings are done, designs are visualized, and the finished building is made compliant with legal and regulatory requirements. But the quality of their images depends on their quality, which is where the professionals come from. Constructing architectural blueprints into real buildings is the responsibility of contractors. They coordinate construction crews, acquire supplies, and supervise the entire building process.
Optimizing Material Procurement and Management
Timber flight specialists play a vital role in this partnership by accurately estimating the amount of timber and materials needed for the project. Their job is to analyze construction plans and specifications to determine the exact amount of lumber needed to minimize waste and maximize material utilization. Lumber moving specialists work closely with contractors and builders to manage the project schedule and budget.
Working together, architects, contractors, and lumber takeoff specialists can reap numerous benefits. First of all, it encourages communication and openness throughout the course of the project. Architects are able to successfully explain their design intent to contractors, who can then relay any realistic limitations or recommendations back to the architects. By ensuring that everyone is aware of the material requirements, lumber takeoff professionals help to prevent misunderstandings and delays later on.
Efficient Resource Allocation and Utilization
Collaboration also encourages creativity and problem-solving. With their practical knowledge, architects may provide innovative design solutions that contractors can execute more successfully. Similarly, alternative building techniques or supplies could be suggested by contractors in order to improve the project's affordability or sustainability. In order to further streamline the construction process, lumber takeoff specialists discover potential for material optimization or substitution.
Risk reduction is one of collaboration's main benefits. There are risks associated with construction projects by nature, which can include overspending, delays, and safety issues. Architects, contractors, and lumber takeoff specialists can collaborate to proactively identify potential dangers and devise mitigation methods. For instance, changes can be made jointly to reduce risks before they worsen if a particular design aspect presents logistical difficulties or goes over budget.
Enhancing Communication and Coordination
Collaboration also results in increased project cost-effectiveness and efficiency. Architects may design buildings that are not only visually beautiful but also practical to build by utilizing each other's knowledge and insights. With precise material estimates from lumber takeoff specialists, contractors may minimize waste and project costs by allocating resources more efficiently and completing projects on time. In the end, this synergy results in increased value for stakeholders and clients.
Apart from providing concrete advantages, collaboration also cultivates a climate of trust and cooperation among involved parties. When contractors, architects, and lumber takeoff specialists collaborate to achieve a common objective, they grow to value each other's knowledge and talents. An environment where ideas are freely shared, problems are solved together, and victories are celebrated as a team is fostered by this collaborative spirit.
Effective cooperation, however, needs purposeful work and dedication from all parties; it does not just happen. It is imperative to develop consistent communication channels to facilitate the smooth exchange of information among architects, contractors, and lumber takeoff specialists. Regular project reviews and meetings are necessary to evaluate results, resolve issues, and adjust plans of action as necessary.
Utilizing Technology for Integrated Workflows
Furthermore, using technology to its full potential can greatly improve teamwork when building projects. The real-time sharing of project information and documents, project management software, building information modeling (BIM) technology, and cloud-based collaboration systems This helps improve stakeholder communication. These digital solutions also automate repetitive operations, improve workflows, and offer insightful data that helps with decision-making.
Conclusion
To sum up, cooperation between contractors, architects, and lumber takeoff experts is essential to the accomplishment of building projects. Using the combined knowledge, ideas and resources of all stakeholders, projects can be completed efficiently, economically and to the highest quality. The growth of the construction industry will necessitate the building of a collaborative culture of creativity, sustainable development and construction excellence to encourage strategies.

This results in the thickening and hardening of the skin and connective tissues. The underlying cause of this immune system malfunction remains unknown. Scleroderma can affect organs such as the kidneys, lungs, chest, digestive system and occasionally even the eyes.
While there is currently no cure for this disorder, healthcare providers have developed strategies to manage its symptoms. To provide treatment it is crucial for doctors to determine which organs are impacted and the severity of the condition. A combination of treatment approaches is often recommended to ensure care – ranging from medications, to lifestyle adjustments.
If you don't see any improvement, your doctor might suggest surgery. You could, in addition, explore treatments like stem cell therapy. The course of action depends on how serious the condition's and the advice of your healthcare provider. Detecting and acting on the issue early is crucial for treatment and recovery.
While scleroderma may sound intimidating, instead of getting anxious, let's take a look to understand this condition better by checking out [scleroderma](https://www.advancells.com/scleroderma-signs-and-symptoms-types-causes-and-treatment/) more details in the blog.

1,866,113 | Django: Using models | From: MDN Web Docs Models Python objects Define the data structure Independent from the... | 0 | 2024-05-27T03:53:10 | https://dev.to/samuellubliner/django-using-models-54bh | webdev, python, django | From: [MDN Web Docs](https://developer.mozilla.org/en-US/docs/Learn/Server-side/Django/Models)
## Models
- Python objects
- Define the data structure
- Independent from the database schema
- Facilitate communication between Django and the database via Object-Relational Mapper
## Designing Models
Create separate models for every object. Models can also be used to represent selection-list options.
Consider the relationships between objects. Relationships include:
- one to one (OneToOneField)
- one to many (ForeignKey)
- many to many (ManyToManyField)
Multiplicities define the maximum and minimum number of each model that may be present in the relationship.
## Model definition
Models:
- Defined in `models.py`
- Extend `django.db.models.Model` class
- Can include fields, methods and metadata
## Fields
- Fields in a model represent columns in a database table.
- Each record (row) in the table contains values for these fields.
- Field types are designated using specific classes that define the type of data stored.
- Field types can also be used for HTML form validation.
## Field Arguments
- https://docs.djangoproject.com/en/5.0/ref/models/fields/#field-options
- `help_text`
- `verbose_name`
- `default`
- `null`
- `blank`
- `unique`
- `primary_key`
## COMMON FIELD TYPES
- https://docs.djangoproject.com/en/5.0/ref/models/fields/#field-types
- `CharField`
- `TextField`
- `IntegerField`
- other fields for different types of numbers
- `DateField`
- `EmailField`
- `FileField`
- `ImageField`
- `AutoField`
- `ForeignKey` specifies one-to-many relationship to another database model
- `ManyToManyField`
## Metadata
- https://docs.djangoproject.com/en/5.0/ref/models/options/
- Declare model-level metadata with `class Meta`
- Useful for controlling the ordering of records returned by queries
- Other metadata options control the database used for the model and how the data is stored
## Methods
### `__str__()`
- Python class method
- Provides a readable string representation of the object
- The string represents individual records
### `get_absolute_url()`
- Generates a URL to view individual records of the model
## Model management
Use model classes to create, update, or delete records, and to run queries.
## Creating and modifying records
- Create a record by instantiating the model and using the model's constructor.
- Then call `save()` to save the object to the database.
- Access fields in the record using dot notation.
- Search for records using the model's objects attribute
## The full list of lookups:
https://docs.djangoproject.com/en/5.0/ref/models/querysets/#field-lookups
## Making queries:
https://docs.djangoproject.com/en/5.0/topics/db/queries/
## Constraints
https://docs.djangoproject.com/en/5.0/ref/models/constraints/
## Defining the LocalLibrary Models
At the top of `/django-locallibrary-tutorial/catalog/models.py`, the boilerplate imports the `models` module, which provides the `models.Model` base class that our models inherit from.
## Genre model
- Stores information about the book genre
- A single `CharField` field is used to describe the genre
- Limited to 200 characters
- Has some `help_text`
- Set to`unique=True`
- One record for each genre
- `a __str__()` method returns the name of the genre
- `get_absolute_url()` method used to access a detail record
## Book model
- Represents all the general information about an available book
- `CharField` is used for the book's title and isbn.
- `unique` as `true` ensures all books have a unique ISBN
- `title` is not set to be unique, because it is possible for different books to have the same name.
- `TextField` for longer summary
- `ManyToManyField` a book can have multiple genres and a genre can have many books
## In both field types:
- The first unnamed parameter should specify the related model class
- either directly by the model class
- or as a string with the name of the related model
- If the associated class is not yet defined, use the model's name as a string in this file
- Setting `null=True` permits the database to store `Null` if no author is selected
- Using `on_delete=models.RESTRICT` prevents the deletion of the book's author if it is referenced by any book
## Warning:
- The default behavior is `on_delete=models.CASCADE`
- This means that if the author is deleted, the book would also be deleted
- Use `RESTRICT` or `PROTECT` to avoid the author being deleted while it is referenced by any book
- Alternatively, use `SET_NULL` to set the book's author to `Null` if the author record is deleted
- The `__str__()` method represents a Book record by its title field
- The `get_absolute_url()` method provides a URL to access a detailed record
## BookInstance model
- Represents a specific copy of a book
- Includes information about whether the copy is available
- The date expected back
- version details
- unique id for the book in the library
- `ForeignKey` identifies the associated Book
- each book can have many copies
- a copy can only have one Book
- `on_delete=models.RESTRICT` ensures the Book cannot be deleted while referenced by a `BookInstance`
- `CharField` represents the specific release
- `UUIDField` for the id field to set it as the `primary_key`
- This allocates a globally unique value for each instance
- `DateField` for the `due_back` date
- status `CharField` defines a choice/selection list
- `__str__()` uses a combination of its unique id and title
## Re-run the database migrations
After models have now been created, re-run database migrations to add them to the database.
```BASH
python3 manage.py makemigrations
python3 manage.py migrate
```

1,864,817 | Zabbix ile Prometheus Metrik Formatında Kafka İzleme | Prometheus: Zaman Serisi Veritabanı Nedir? Prometheus, sistemler ve servislerden veri... | 0 | 2024-05-27T05:37:29 | https://dev.to/aciklab/zabbix-ile-prometheus-metrik-formatinda-kafka-izleme-3knk | zabbix, prometheus, kafka, monitoring | #Prometheus: Zaman Serisi Veritabanı Nedir?
Prometheus, sistemler ve servislerden veri toplamak için kullanılan açık kaynaklı bir zaman serisi veritabanıdır. Verileri "pull" modeli aracılığıyla alır, yani Prometheus, tanımlı hedeflerden düzenli aralıklarla veri çeker. Bu veriler, Prometheus'un yerleşik arayüzünde PromQL (Prometheus Query Language) kullanılarak sorgulanabilir ve görselleştirilebilir. Grafana gibi araçlarla entegrasyonu sayesinde, daha zengin görselleştirme ve kapsamlı dashboard oluşturma imkanı sunar.
#Exporter Nedir?
Exporter'lar, çeşitli kaynaklardan metrikleri toplayan ve bu verileri Prometheus'un anlayabileceği formatta HTTP üzerinden sunan araçlardır. Bu, Prometheus'un hedef sistemlerde doğrudan çalışmasına gerek kalmadan dış kaynaklardan veri toplamasını sağlar.
#Zabbix ile Prometheus Metriklerinin Entegrasyonu
Zabbix, güçlü bir açık kaynak izleme çözümüdür ve Prometheus metriklerini entegre etmek mümkündür. Bu rehber, Prometheus'dan toplanan metriklerin Zabbix kullanılarak nasıl izlenebileceğini adım adım açıklar.
#Gereksinimlerin Listesi:
- **Zabbix sunucusu:** İzleme yapılacak ana sistem.
- **Exporter:** Bu rehberde kullanılacak olan JMX Exporter.
- **Kafka sunucusu:** Metrik kaynağı olarak hizmet veren sunucu.
Docker kullanarak Kafka sunucusunu ve bağlantılı Zookeeper servisini başlatıyoruz.
```bash
kafka@kafka:~$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
7e5f046d5fa4 bitnami/zookeeper:latest "/opt/bitnami/script…" 6 minutes ago Up 6 minutes 2888/tcp, 3888/tcp, 0.0.0.0:2181->2181/tcp, :::2181->2181/tcp, 8080/tcp kafka_zookeeper_1
5a28b5f7ca84 bitnami/kafka:latest "/opt/bitnami/script…" 6 minutes ago Up 6 minutes 0.0.0.0:9091-9092->9091-9092/tcp, :::9091-9092->9091-9092/tcp, 0.0.0.0:9999->9999/tcp, :::9999->9999/tcp kafka_kafka_1
```
## Adım 1: Metrik Seçimi ve Tanımlama
Kafka sunucumda çalışan ve 192.168.1.9:9091 adresinde erişilebilen Exporter üzerinden, belirli bir Kafka topic'i için trafik metriklerini seçiyorum.
Seçilen metrikler, topic üzerinden gelen ve giden veri akışını ve talep sayısını içerir.
```bash
kafka_server_brokertopicmetrics_meanrate{name="BytesInPerSec",topic="test_topic",} 82.34778932997635
kafka_server_brokertopicmetrics_meanrate{name="BytesOutPerSec",topic="test_topic",} 112.90497508080351
kafka_server_brokertopicmetrics_meanrate{name="TotalFetchRequestsPerSec",topic="test_topic",}
```
## Adım 2: Zabbix Template Oluşturma
Zabbix içinde "Prometheus Metrics" adında bir template oluşturarak, seçilen metrikleri bu template altına item olarak ekleyeceğim.
## Adım 3: HTTP Agent oluşturulmalı
Zabbix sunucusunda, Exporter'dan metrikleri çekecek bir HTTP Agent kuruyorum. Bu agent, metriklerin düzenli olarak Zabbix sunucusuna aktarılmasını sağlar.
Yeni bir item oluşturarak "Prometheus Metrics" template'ine ekliyorum.
Item yapılandırmasını tamamladıktan sonra, 'Test' butonuna tıklayarak HTTP Agent'ın düzgün çalışıp çalışmadığını kontrol ediyorum.
## Adım 4: Bağımlı Öğelerin (Dependent Item) Oluşturulması
Bağımlı öğeler, ana metriklerden türetilen ve daha detaylı analiz için kullanılan veri öğeleridir.
Bu adımda, 'BytesInPerSec' metriğine dayalı olarak "topic_bytes_in_rate" adında bir dependent item oluşturuyorum. Bu dependent item, belirli bir Kafka topic'inden gelen veri akış hızını temsil eder ve ölçümleri daha spesifik bir kontekste yerleştirir.
Oluşturduğum dependent item için preprocessing sekmesine giderek "add" butonuna tıklayarak yeni bir preprocessing kuralı ekliyorum. Bu kural, Prometheus'un metrik formatını Zabbix'in anlayacağı formata dönüştürür.
Kullanılacak parametre, Prometheus Pattern'dir ve metrik değerlerini doğru bir şekilde parse etmek için önceden belirlenen Prometheus sorgusu kullanılır.
Örneğin, `kafka_server_brokertopicmetrics_meanrate{name="BytesInPerSec", topic="test_topic"}` metriği, Kafka sunucusundaki belirli bir topic'e gelen veri miktarını ölçer. Bu örnek metrik, rehberimizde kullanılan örnek bir metrik değeridir.
Bu sürecin çalışması için, seçilen her metrik için ayrı bir dependent item oluşturulmalıdır.
## Adım 5: Kafka Server'a Template Ekleme
Oluşturduğumuz bu template'i, izlemek istediğimiz Kafka sunucusuna ekliyoruz.
## Adım 6: Metrikleri Kontrol Etme
Son adım olarak, Zabbix arayüzünden 'Monitoring > Hosts > Kafka Sunucusu > Latest Data' yolunu takip ederek sunucumuzda izlemekte olduğumuz metriklerin güncel verilerine ulaşıyoruz.
# Sonuç
Bu rehber, Prometheus ve Zabbix kullanarak Kafka sunucusundan metrik toplama sürecini adım adım ele almakta ve bu süreci nasıl yöneteceğinizi açıklamaktadır. Prometheus'un güçlü zaman serisi veri toplama kabiliyeti ve Zabbix ile olan entegrasyonu sayesinde, karmaşık sistemlerin izlenmesi ve yönetilmesi kolaylaşmaktadır.

## What I Built
I built a Blog Application using AWS Amplify and Angular where we can create a Blog by providing Title and description, list all the blogs and read a specific Blog.
## Demo and Code
<!-- Share a link to your Amplify App and source code. Include some screenshots as well. -->
SOURCE CODE: https://github.com/PreethiVuchuru27916/amplify-angular-template
App URL: https://main.dvwj8fwztcl1x.amplifyapp.com/blog-list/0fefede3-f5ac-4f8c-be69-4ed412601c8d
[1] Create Blog Button provides the user with a text editor to start working on the blog.
[2] Used the ngx-editor to build the text editor and provided a scroll to add content of any size.
[3] Have a publish option to create the Blog and show it under the list of Blogs
[4] List of Blogs
[5] Read more option on the list will take us to the individual Blog.
[6]Utilized Sign out and Sign In and Create Account features provided by Amplify
## Integrations
<!-- Tell us which qualifying technologies you integrated, and how you used them. -->
- I have create a model called Blog that has title and description. To save it to a personal cloud sandbox, I ran the npx ampx sandbox
to get amplify_outputs.json file. This allowed me to make backend updates in a private cloud space.
- I have used authentication module and @aws-amplify/ui-angular for building the Sign Up, Sign In, Create Account. Also tried out the customization available for the Authenticator.
<!-- Reminder: Qualifying technologies are data, authentication, serverless functions, and file storage as outlined in the guidelines -->
## FUTURE WORK
- Will add a cover image that will make use of the File Storage concepts in AWS Amplify.
- Will add notifications to be sent over by using serverless functions.
- Will add draft versions and make sure only the loggedin users can see the drafts of their own.
<!-- Let us know if you developed UI using Amplify connected components for UX patterns, and/or if your project includes all four integrations to qualify for the additional prize categories. -->
<!-- Team Submissions: Please pick one member to publish the submission and credit teammates by listing their DEV usernames directly in the body of the post. -->
<!-- Don't forget to add a cover image (if you want). -->
Thank you Dev.to for interesting challenges :) I knew about the challenge really late and was not able to finish what I had in mind. But something is better than nothing and hence my submission. Challenges like these are a great opportunity to explore new technologies. Excited for more challenges in future.

## Integrations
### Tech Stack
- **Backend**: AWS Amplify
- **Frontend**: Angular 17, Angular Material, Tailwind CSS
- **AWS Technologies**: Data (DynamoDB), Authentication (Cognito), Serverless Functions (Lambda), File Storage (S3), AI (Bedrock)
- **Hosting**: AWS Amplify
**Connected Components and Feature Full**
This project uses Amplify connected components for Angular - **Authenticator** for users to sign up and log in.
This project also integrates all four integrations - **Data, Authentication, Serverless Functions, File Storage**
### AWS Amplify
**Architecture**
**Authentication**
Utilizes AWS Amplify Authentication for user sign-up and login via email which uses AWS Cognito services.
Configured in `amplify/auth/resource.ts`
```typescript
export const auth = defineAuth({
loginWith: {
email: true,
}
});
```
Implemented with the Amplify UI component `<amplify-authenticator>` for Angular.
**Data**
Utilizes AWS Amplify Data to store information about **Users**, **Companies**, and **Jobs** which uses AWS DynamoDB. Database Design is shown above.
Configured in `amplify/data/resource.ts`
**Database Design**
**Storage**
AWS Amplify S3 Storage is used for storing company **logos** and job seeker **resumes**.
Configured in `amplify/storage/resource.ts`
```typescript
export const storage = defineStorage({
name: 'recruitifyFiles',
access: (allow) => ({
'companyLogos/*': [
allow.authenticated.to(['read', 'write']),
allow.guest.to(['read', 'write'])
],
'resumes/*': [
allow.authenticated.to(['read', 'write']),
allow.guest.to(['read', 'write'])
],
})
});
```
The files were uploaded using `uploadData` like below
```typescript
const result = await uploadData({
data: this.previewUrl,
path: `companyLogos/${this.authService?.userProfile?.id}`,
}).result;
```
And the files were downloaded when necessary using `downloadData` like below
```typescript
downloadData({ path: profile.data[0].resume })
```
**Functions**
AWS Amplify Lambda Functions are used to send **New Job Notifications** to job seekers matching their skill set and **Generate Job Description** to generate job descriptions for job creators.
Used AWS Amplify **AppSync GraphQL API** inside the function to find relevant job seekers and create new job notifications.
Used **AWS Bedrock** with Mistral AI Model inside the function to generate job description.
Configured in `amplify/functions/new-job/handler.ts`
Triggered when a new job is created by an employer using a mutation in data like the below:
```typescript
sendJobNotification: a.mutation()
.arguments({ jobId: a.string(), companyId: a.string() })
.returns(a.string())
.authorization(allow => [allow.publicApiKey()])
.handler(a.handler.function(newJob))
```
```typescript
client.mutations.sendJobNotification({
jobId: job.data?.id,
companyId: job.data?.companyId
}).then((job) => {
console.log(job)
})
```
Triggered generate job description like the below:
```typescript
generateJobDescription: a.mutation()
.arguments({ title: a.string(), minExperience: a.float(), skills: a.string(), domain: a.string() })
.returns(a.string())
.authorization(allow => [allow.publicApiKey()])
.handler(a.handler.function(generateJobDescription))
```
```typescript
client.mutations.generateJobDescription({
title: this.createJobForm.value.title,
skills: this.skills.join(','),
domain: this.createJobForm.value.domain,
minExperience: this.createJobForm.value.minExperience,
}).then((response) => {
console.log(response);
if (response?.data) {
this.createJobForm.patchValue({
description: response.data
})
}
}).finally(() => {
this.loadingService.hide();
})
```
Used **Mistral 7B** model with prompt like this:
```typescript
const text = `
Job Title: ${title}
Job Domain: ${domain}
Job Min Experience: ${minExperience} years
Job Required Skills: ${skills}
`
const prompt = `Your task is to generate a job description for below-given job details.
Job Details: ${text}
Job Description: `
```
And invoke the model like below:
```typescript
const input = {
modelId: "mistral.mistral-7b-instruct-v0:2",
contentType: "application/json",
accept: "application/json",
body: JSON.stringify({
prompt: `<s>[INST] ${prompt} [/INST]`,
max_tokens: 2000,
temperature: 0.5,
}),
} as InvokeModelCommandInput;
```
**Hosting**
Utilised AWS Hosting for seamless deployment of the application.
## Future Scope
- **Application Notifications**: Notifications for Job Application status changes for both job seekers and employers
- **Realtime chat messaging**: Realtime chat messaging between job seeker and employer
## Conclusion
**Recruitify** leverages the power of **AWS Amplify** to deliver a robust, full-stack application. A lot to learn while working with AWS and AWS Amplify toolkit along with Angular on this project. | thegeekyamit |

Hi there,
<strong>Are you regulars to Perl conference?</strong>
If yes then you have two upcoming conferences <a href="https://tprc.us/tprc-2024-las">The Perl and Raku Conference in Las Vegas</a> and <a href="https://act.yapc.eu/lpw2024">London Perl and Raku Conference</a>. Depending on your availability and convenience, I would highly recommend you register your interest to your choice(s) of conference. And if you are attending then do take the plunge give your first talk if you have not done so before. It doesn't have to be long talk, you can try quick 5 minutes lightning talk to begin with.
<strong>How about become a sponsor to the conference?</strong>
Believe it or not, it is vital that we provide financial support in the form of sponsor. So if you know someone who is in a position to support these events then please do share this <a href="https://www.perl.com/article/this-is-your-opportunity-to-sponsor-the-perl-and-raku-conference-2024">TPRC 2024 Sponsors</a> and <a href="https://www.perl.com/article/announcing-the-london-perl-raku-workshop-2024-lpw">LPW 2024 Sponsors</a> with them. It would be a big help to organise such events.
<strong>Keynote speakers for TPRC 2024...</strong>
I came across this <a href="https://ovid.github.io/blog/being-a-keynote-speaker.html">post</a> by <strong>Curtis Poe</strong> where it is announced that <strong>Curtis</strong> is going to be keynote speaker at the event. Well there is a bonus for all attending the event, <strong>Damian Conway</strong> would be giving a keynote remotely. I am sure, it is going to be a memorable moment to celebrate the <strong>25th anniversary</strong>. Similarly, <strong>London Perl Workshop</strong> would be celebrating <strong>20th anniversary</strong> this year. I wanted to attend the TPRC 2024 in Las Vegas but for personal reason I am unable to attend. What a shame but at least I am definitely going to be part of LPW 2024 as it is local to me. No need to book travel ticket or reserve hotel room.
<strong>How many of you know about Pull Request Club?</strong>
The <a href="https://pullrequest.club/hello">Pull Request Club</a> is run by <strong>Kivanc Yazan</strong>. It started in <strong>Jan 2019</strong>. I had the pleasure to be associated with it since the beginning. I never missed the assignment until the last I contributed in <strong>January 2022</strong>. Unfortunately I faced too much distraction and missed the fun ever since. I found this <a href="https://kyzn.org/pull-request-club-2021-2023-report">annual report</a> by the creator himself. If you like contributing to opensource projects then you should join the club and have fun.
For all cricket fans in <strong>India</strong>, did you watch the final of <strong>IPL 2024</strong>? I did and happy to see my favourite team, <strong>Kolkatta Knight Riders</strong> lifting the trophy. Although, <strong>SRH</strong>, the loosing team was my favourite too but it didn't play to their capability. I am now looking forward to the <strong>T20 World Cup</strong> next. How about you?
Today is <strong>Bank Holiday</strong> in England, so relax day for me. Enjoy rest of the newsletter. Last but not least, please do look after yourself and your loved ones.

One of the biggest advantages of metallic shoes is their versatility. They can be dressed up or down, making them suitable for various occasions. For instance, metallic sandals can add a chic touch to a casual summer dress, while metallic heels can elevate a simple cocktail dress to something extraordinary. Even a basic jeans-and-tee outfit can be transformed into a trendy look with the addition of metallic sneakers.
Perfect for All Seasons
Metallic shoes are not confined to a particular season. In the summer, metallic sandals or espadrilles can complement sun-kissed skin and bright outfits. During the colder months, metallic boots can add a festive touch to your winter wardrobe, pairing beautifully with darker tones and heavier fabrics.

Thanks to the FMZ Platform, I will share more content related to quantitative development and work together with all traders to maintain the prosperity of the quant community.
- Do you often struggle to distinguish between trends and fluctuations?
- Have you been stopped out by the back-and-forth disorderly market?
- Are you having difficulty understanding the current market situation?
- Do you do trend trading and hope to filter out fluctuations?
Haha, you've come to the right place. Today, I will bring you the construction and application of market noise! As we all know, financial markets are full of noise. How to quantitatively model and depict market noise is very important. The depiction of noise can better help us distinguish the current state of the market and predict future possibilities!
> PART1 Noise discrimination is very important for financial market trading.
The time series in the financial market is characterized by a high signal-to-noise ratio, most of the time, the market fluctuations are unclear, and even during trending markets, situations like taking four steps forward and three steps back often occur. Therefore, defining, identifying and classifying market noise in the financial market is very important and has practical significance. Kaufman's book provides a comprehensive explanation and modeling of this characteristic of noise.
> PART2 Construction of Noise - ER Efficiency Coefficient
The net value of the starting and ending points of price changes divided by the sum of all pairwise price changes during the period.
The difference between point A and point B divided by the sum of the 7 intermediate movements.
It demonstrates the different noise levels exhibited by various price operation modes under the same price movement range. A straight line indicates no noise, minor fluctuations around the straight line represent medium noise, and large swings symbolize high noise.
> PART3 Construction of Noise - Price Density
The definition here is: Drawing the high and low points of price movements over a period of time, pulling the highest and lowest prices during this period into a box. The so-called price density refers to the number of price points that can be accommodated within the box.
Compared to the ER efficiency coefficient, the measurement method of price density takes more into account the highest and lowest prices of each K-line.
> PART4 Construction of Noise - Fractal Dimension
The fractal dimension cannot be measured accurately, but it can be estimated using the following steps within the past n terms:
> PART5 Construction of Noise - Other Methods
CMI = (close[0] - open[n-1]) / (Max high(n) - Min low(n));
When the noise is lower, during this period, the net value at the beginning and end infinitely approaches the difference between the highest and lowest prices, with CMI infinitely approaching 1.
The results obtained from the construction methods of various noise measurements are highly similar. The core is to compare the net changes and change processes or extreme values of a period of movement, and choose the construction method that you prefer or think is more reasonable.
> PART6 Dividing market styles from the perspectives of noise and volatility.
Volatility and noise are different dimensions to characterize the market. The sum of price changes in the two types of price models mentioned above is the same, so their volatility is the same, but net value changes more significantly and noise is lower.
Therefore, noise and volatility are two different perspectives that can be used to classify market styles. If we take persistence and volatility of trends as the x-axis and y-axis respectively to construct a Cartesian coordinate system, we can divide the fluctuation status of market prices into four categories:
- Good sustainability, high volatility - smooth trend.
- Good sustainability, low volatility - bumpy trend.
- Persistent poor performance, low volatility - narrow range consolidation.
- Persistent poor performance, high volatility - wide range fluctuations.
It should be pointed out that there are no absolute standards for what is called wide range and narrow range, it has to be relative to the level and system of one's own trading, just like the setting of the trading period, which is extremely personalized. Moreover, we can only determine the current state of the market by examining a period in the past. However, we cannot predict what state the market will enter next.
Of course, the four types of fluctuations are not completely random during conversion. In the most ideal state, a smooth trend is often followed by wide-range oscillations, slowly unloading momentum; then it enters narrow-range consolidation, the market is very inactive, and bulls and bears are stuck in a stalemate; when the market is compressed to a critical point, it explodes again and the trend begins; this is an oversimplified ideal model - reality is much more complex. For example, after narrow-range consolidation there may not necessarily be a trend - it could also be wide-ranging oscillation. After a smooth trend there might not necessarily be wide-ranging oscillation - it could continue to reach new highs or lows. Moreover, it's difficult to develop four strategies that excel at handling four different market conditions and can adapt as needed. So for now, I still think we can only develop strategies that make money in certain markets while minimizing losses in unfavorable ones.
> PART7 Impact of Noise on Related Transactions
The profit factor of the 40-day moving average strategy (going long above the 40-day line and short below, total profit/total loss) is regressed with the 40-day noise (ER efficiency coefficient). It can be seen that the higher the noise, the lower the profit factor of trend strategies. And we can conclude: low noise is beneficial for trend trading, high noise is beneficial for mean reversion trading.
The concept of market noise is very important in determining trading styles. Before developing corresponding trading strategies, we need to outline the contours of the market.
> PART8 Market Maturity and Noise
Over the past 20 years, the noise attribute of the North American stock index market has experienced a steady rise.
Financial markets in various regions are gradually maturing, with noise levels increasing progressively, and the maturity is coming quickly.
A study was conducted on the stock index markets of various countries. The market on the far right is the most mature and also has higher noise, while the one on the far left is immature with lower noise. It can be observed that Japan has the most mature market, followed by economies like Hong Kong, China, Singapore, and South Korea. On the far left are relatively immature markets, such as Vietnam and Sri Lanka.
The noise in the Bitcoin market for each quarter is approximately 0.2-0.3, and it's in a cyclical state.
Thanks to the FMZ Platform, for not closing its doors and reinventing the wheel, but providing such a great place for traders to communicate. The road of trading is full of ups and downs, but with warmth from fellow traders and continuous learning from the shared experiences of seniors on the FMZ platform, we can keep growing. Wishing FMZ all the best and may all traders enjoy long-lasting profits.

Hey there, fellow coder! 🌟 If you're diving into Vue 3, you've probably heard about the Composition API. It’s one of the coolest new features that makes organizing and reusing code a breeze. Whether you're new to Vue or coming from the Options API, this step-by-step tutorial will guide you through the Composition API with clear explanations and practical examples. Let's get started!
## What is the Composition API?
The Composition API is a set of additive APIs that allow you to use function-based composition to build your components. It’s designed to improve code organization and reuse, especially in larger applications.
### Why Use the Composition API?
- **Better Code Organization**: With the Composition API, you can group related logic together in a more natural way. This makes your components easier to read and maintain.
- **Reusability**: The Composition API allows you to easily reuse logic across different components, making your code more modular and less repetitive.
- **TypeScript Support**: The Composition API has improved support for TypeScript, making it easier to write type-safe code.
## Setting Up Your Project
First things first, make sure you have Vue 3 set up. If you don’t, you can quickly create a new project using the Vue CLI:
```bash
npm install -g @vue/cli
vue create my-vue-app
cd my-vue-app
npm run serve
```
Now, let’s dive into some examples!
## Basic Example
### The Options API Way
Before we jump into the Composition API, let’s see how we’d typically do things with the Options API:
```javascript
<template>
<div>
<p>{{ message }}</p>
<button @click="updateMessage">Update Message</button>
</div>
</template>
<script>
export default {
data() {
return {
message: 'Hello, Vue!'
}
},
methods: {
updateMessage() {
this.message = 'Hello, Composition API!'
}
}
}
</script>
```
### The Composition API Way
Now, let's refactor this using the Composition API:
```javascript
<template>
<div>
<p>{{ message }}</p>
<button @click="updateMessage">Update Message</button>
</div>
</template>
<script>
import { ref } from 'vue';
export default {
setup() {
const message = ref('Hello, Vue!');
const updateMessage = () => {
message.value = 'Hello, Composition API!';
};
return {
message,
updateMessage
};
}
}
</script>
```
- **ref**: The `ref` function is used to create a reactive reference to a value. This means that when the value changes, Vue will automatically update the DOM to reflect the new value. To access the value stored in a `ref`, you need to use the `.value` property.
- **setup()**: The `setup` function is a new lifecycle hook in Vue 3 where you can define your component's logic using the Composition API. This function runs before the component is created, allowing you to set up reactive state and other functionalities early on.
## Reactive State
### Using `reactive`
If you need a more complex state, use `reactive` to create a reactive object:
```javascript
<template>
<div>
<p>{{ state.count }}</p>
<button @click="increment">Increment</button>
</div>
</template>
<script>
import { reactive } from 'vue';
export default {
setup() {
const state = reactive({
count: 0
});
const increment = () => {
state.count++;
};
return {
state,
increment
};
}
}
</script>
```
- **reactive**: The `reactive` function converts an object into a reactive object. This means that Vue will track changes to any properties within the object and update the DOM accordingly. Use `reactive` when you have a state that involves multiple properties or more complex data structures.
## Watchers and Computed Properties
### Watchers
Watchers allow you to perform side effects in response to state changes. This is useful for tasks like making API calls when a certain piece of state changes.
```javascript
import { ref, watch } from 'vue';
export default {
setup() {
const count = ref(0);
watch(count, (newCount, oldCount) => {
console.log(`Count changed from ${oldCount} to ${newCount}`);
});
const increment = () => {
count.value++;
};
return {
count,
increment
};
}
}
```
- **watch**: The `watch` function is used to track changes to a reactive value or a ref. When the value changes, the callback function is executed. This is useful for scenarios where you need to perform actions based on state changes, like making API calls or updating other parts of your application.
### Computed Properties
Computed properties are reactive and cache their results, which means they only recompute when their dependencies change. This is useful for expensive calculations that depend on reactive state.
```javascript
import { ref, computed } from 'vue';
export default {
setup() {
const count = ref(0);
const doubleCount = computed(() => count.value * 2);
const increment = () => {
count.value++;
};
return {
count,
doubleCount,
increment
};
}
}
```
- **computed**: The `computed` function creates a reactive value that is automatically updated when its dependencies change. It also caches the result until the dependencies change, which can improve performance for expensive calculations. Computed properties are useful for deriving state that depends on other reactive values.
## Lifecycle Hooks
### Using Lifecycle Hooks
You can use lifecycle hooks within the `setup` function using Vue's lifecycle methods. This allows you to perform actions at specific stages of the component's lifecycle, such as when the component is mounted or unmounted.
```javascript
import { ref, onMounted, onUnmounted } from 'vue';
export default {
setup() {
const count = ref(0);
onMounted(() => {
console.log('Component mounted');
});
onUnmounted(() => {
console.log('Component unmounted');
});
const increment = () => {
count.value++;
};
return {
count,
increment
};
}
}
```
- **onMounted**: The `onMounted` function is called when the component is mounted to the DOM. This is a good place to perform setup tasks that require access to the DOM, such as fetching data or initializing third-party libraries.
- **onUnmounted**: The `onUnmounted` function is called when the component is unmounted from the DOM. This is a good place to perform cleanup tasks, such as removing event listeners or cancelling API requests.
## Composable Functions
### Creating Reusable Logic
One of the main benefits of the Composition API is the ability to extract and reuse logic across components. These reusable pieces of logic are called composables.
```javascript
// useCounter.js
import { ref } from 'vue';
export function useCounter() {
const count = ref(0);
const increment = () => {
count.value++;
};
return {
count,
increment
};
}
```
### Using Composables in Components
```javascript
<template>
<div>
<p>{{ count }}</p>
<button @click="increment">Increment</button>
</div>
</template>
<script>
import { useCounter } from './useCounter';
export default {
setup() {
const { count, increment } = useCounter();
return {
count,
increment
};
}
}
</script>
```
- **Composables**: Composables are functions that encapsulate and reuse logic across components. They allow you to organize your code more effectively and make it easier to share functionality between different parts of your application. By using composables, you can keep your components clean and focused on their specific responsibilities.
The Vue 3 Composition API is a powerful tool that enhances the flexibility and organization of your code. By understanding and using `ref`, `reactive`, `computed`, `watch`, and lifecycle hooks, you can create cleaner and more maintainable components. Don’t be afraid to experiment and refactor your existing components to take advantage of these new capabilities. Happy coding! 🚀

Whether chronic conditions or acute injuries cause it, managing pain effectively remains a significant challenge for many individuals, especially in a diverse and expansive state like Wisconsin. People often seek solutions to alleviate their suffering and improve their overall well-being.
In this guide, we will focus on the complex landscape of [pain management in Wisconsin](https://www.mwsportsandspine.com/), delving into the various approaches available to individuals as they navigate their unique journeys toward relief and wellness. Pain is a universal human experience, yet managing it effectively remains a significant challenge for many individuals, particularly in a diverse and expansive state like Wisconsin. From chronic conditions to acute injuries, pain can profoundly impact one's quality of life, leading many to seek solutions to alleviate suffering. In this comprehensive guide, we explore Wisconsin's multifaceted landscape of pain management, shedding light on the various approaches available to individuals navigating this complex journey.
**Understanding the Spectrum of Pain:**
Pain comes in many forms, each requiring a tailored approach to management. Acute pain, typically resulting from injury or surgery, is often short-lived and can be effectively managed with medications and rest. Chronic pain can persist for a long time, posing greater challenges to those affected. Conditions such as fibromyalgia, arthritis, and neuropathy are examples of chronic pain disorders that demand a comprehensive and holistic approach to treatment.
**Holistic Pain Management Techniques:**
While medications plays a crucial role in pain management in Wisconsin, holistic approaches offer complementary strategies to address pain from multiple angles. Mindfulness practices can help individuals cultivate resilience and reduce the emotional toll of chronic pain. Nutrition also plays a vital role, with anti-inflammatory foods like green vegetables, fruits, and omega-3 fatty acids supporting overall health and well-being. Furthermore, regular exercise, tailored to one's abilities and limitations, can improve flexibility, strength, and mood while reducing pain intensity.
**Medical Interventions for Pain Relief:**
In cases where conservative measures prove inadequate, medical interventions may be necessary to relieve and restore function. Prescription medications, ranging from nonsteroidal anti-inflammatory drugs (NSAIDs) to opioid analgesics, can help manage pain symptoms. However, their use requires careful monitoring to mitigate risks of dependence and side effects. Injections, such as corticosteroids or nerve blocks, offer targeted relief by delivering the right medication directly, reducing inflammation, and blocking pain signals. In severe cases, surgical interventions are considered to address underlying structural issues contributing to chronic pain.
**Spotlight on Local Pain Management Resources:**
Wisconsin has diverse pain management clinics and practitioners dedicated to providing comprehensive care to those in need. From Milwaukee to Madison, Green Bay to Eau Claire, individuals can access a wide range of specialists, including pain physicians, physical therapists, chiropractors, and acupuncturists.

1,864,661 | Easy AWS permissions for your EKS workloads: Pod Identity - An easy way to grant AWS access | 📚 Introduction: Running applications on Kubernetes is great, but sometimes they need to talk to... | 0 | 2024-05-27T05:13:00 | https://dev.to/aws-builders/easy-aws-permissions-for-your-eks-workloads-pod-identity-an-easy-way-to-grant-aws-access-13oj | eks, aws, kubernetes, security | 📚 Introduction:
Running applications on Kubernetes is great, but sometimes they need to talk to other AWS services like S3 or DynamoDB. In the past, setting up the right permissions for your Kubernetes apps to access these AWS services was a bit of a headache. You had to jump through hoops and follow complex instructions.
But now, there's a new feature called EKS Pod Identity that makes granting AWS permissions to your Kubernetes apps a breeze. With just a few clicks (or commands), you can give your apps the AWS access they need, without any complicated setup.
EKS Pod Identity is a part of Amazon's Elastic Kubernetes Service (EKS), and it's designed to make your life as a Kubernetes user much easier. It's a simple, straightforward way to manage AWS permissions for your Kubernetes workloads, saving you time and effort.
In this blog post, we'll explore what EKS Pod Identity is, how it works, and why you should consider using it for your Kubernetes applications running on EKS.
## Grant AWS Permissions to Your K8S Apps:
When you're running Kubernetes apps on Amazon EKS (Elastic Kubernetes Service), you have two main options to give them the ability to access other AWS services like S3 or DynamoDB:
**_1. IAM Roles for Service Accounts (IRSA):_**
This method allows associating IAM roles with Kubernetes service accounts. It supports various Kubernetes environments on AWS like EKS, EKS Anywhere, OpenShift, and self-managed clusters. IRSA uses core AWS services like IAM and doesn't directly depend on the EKS service.
_**2. EKS Pod Identity:**_
This EKS-specific feature simplifies how cluster admins can configure IAM permissions for Kubernetes apps. It allows directly mapping an IAM role to a Kubernetes service account through EKS APIs. Pods under the associated service account can automatically obtain temporary AWS credentials.
Both options achieve the same goal - granting your Kubernetes workloads on EKS the necessary AWS permissions. However, EKS Pod Identity is a more EKS-specific and simplified approach, while IRSA is a more general solution that works across different Kubernetes environments on AWS.
{% gist https://gist.github.com/seifrajhi/af53b892b6bf8a70efccf564065feca3 file=Pod_Identity-VS-IRSA.md %}
## Pod Identity hands-on:
**_Deploy the cluster:_**
Execute the following commands to provision the EKS Cluster:
```
git clone https://github.com/seifrajhi/aws-eks-terraform.git
cd aws-eks-terraform
terraform init
terraform plan
terraform auto-approve
```
_**Deploy Pod Identity agent:**_
To use EKS Pod Identity in your cluster, the EKS Pod Identity Agent addon must be installed on your EKS cluster. Let's install it using the below command.
```
aws eks create-addon --cluster-name eks-pod-identity-demo --addon-name eks-pod-identity-agent
aws eks wait addon-active --cluster-name eks-pod-identity-demo --addon-name eks-pod-identity-agent
```
Go to EKS Console and view the eks-pod-identity-agent under the Add-on tab.
You can also take a look at what has been created in your EKS cluster by the new addon:
```
$ kubectl -n kube-system get daemonset eks-pod-identity-agent
# Or
$ kubectl -n kube-system get pods -l app.kubernetes.io/name=eks-pod-identity-agent
```
_**Deploy the sample app:**_
Below is the manifest we will be using:
```
apiVersion: v1
kind: Namespace
metadata:
name: demo-ns
---
apiVersion: v1
kind: ServiceAccount
metadata:
name: demo-sa
namespace: demo-ns
---
apiVersion: v1
kind: Pod
metadata:
name: demo-app
namespace: demo-ns
labels:
app: demo-app
spec:
serviceAccountName: demo-sa
containers:
- name: demo-app
image: amazon/aws-cli:latest
command: ['sleep', '36000']
restartPolicy: Never
```
Run the below command to deploy the app:
```
kubectl apply -f manifests.yaml
```
**_Configure Amazon EKS Pod Identity:_**
Create a trust policy and configure the principal to `pods.eks.amazonaws.com`.
IAM_ROLE_TRUST_POLICY.json:
```
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Principal": {
"Service": "pods.eks.amazonaws.com"
},
"Action": [
"sts:AssumeRole",
"sts:TagSession"
]
}
]
}
```
Using the above trust policy, create the IAM role.
```
aws iam create-role \
--role-name eks-pod-s3-readonly-access \
--description "allow EKS pods readonly acces to S3" \
--assume-role-policy-document file://IAM_ROLE_TRUST_POLICY.json \
--output text \
--query 'Role.Arn'
```
Then create the IAM Policy for S3 to list buckets and get Objects.
IAM_POLICY.json:
```
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"s3:ListAllMyBuckets"
],
"Resource": "*"
},
{
"Effect": "Allow",
"Action": [
"s3:GetObject",
"s3:GetObjectTagging"
],
"Resource": "*"
}
]
}
```
Create the IAM Policy:
```
aws iam create-policy --policy-name eks-pod-s3-readonly-access-policy --policy-document file://IAM_POLICY.json --output text --query Policy.Arn
```
Attach the policy to the IAM Role:
```
aws iam attach-role-policy --role-name eks-pod-s3-readonly-access \
--policy-arn eks-pod-s3-readonly-access-policy
```
**_Create Pod Identity association:_**
Create the EKS Pod Identity association for the Service account `demo-sa` in Namespace `demo-ns` for the IAM Role `eks-pod-s3-readonly-access`:
```
$ export IAM_ROLE_ARN=$(aws iam get-role --role-name eks-pod-s3-readonly-access | jq -r '.Role.Arn')
$ aws eks create-pod-identity-association \
--cluster-name eks-pod-identity-demo \
--namespace demo-ns\
--service-account demo-sa \
--role-arn $IAM_ROLE_ARN
```
We can get the list of current EKS Pod Identity associations using the below command:
```
aws eks list-pod-identity-associations --cluster-name eks-pod-identity-demo
```
**_Test AWS EKS Pod Identity:_**
Run the below command:
```
kubectl -n demo-ns exec -it demo-app -- aws s3 ls
```
The App can list of S3 Buckets 🎉.
**_Conclusion:_**
In short, EKS Pod Identity is a great solution that lets you easily give your Kubernetes apps running on Amazon EKS the AWS permissions they need.

Conducting frequent audits and penetration testing to achieve ISO-27001 compliance builds customer trust. Blockchain integration protects payment infrastructure while machine learning algorithms combat emerging fraud typologies in real-time. Maintaining a dedicated cybersecurity team for monitoring threats allows swift response to exploit fixes before incidents occur. With relentless focus on fortifying defenses across the tech stack proactively, developers get ahead of the evolving risk landscape.
Adaptive Design for Cross-Platform Compatibility
With mobile gaming dominating market share, developers must deliver cross-platform compatible 3 Patti games playable across iOS, Android, tablets, desktops and browsers from a single codebase. Adaptive design methodologies allow the same code to dynamically scale UIs as per form factors and input modes. Ensuring wide accessibility across devices future-proofs distribution and play. Developers must continuously test gameplay across an expanding matrix of phones, tablets, browsers, TVs, wearables and modality inputs to retain seamless operability.
Increasing device fragmentation demands planning for many permutations from day one. Building reactive, scalable UI abstractions simplifies supporting new resolutions or orientations without overhead. Componentizing UX elements also eases crafting platform-specific experiences if needed, while sharing majority modules. Leveraging emulators and open devices labs assists compatibility evaluations. Most vitally, adaptive thinking must pervade design philosophy – upholding accessibility and seamless functionality irrespective of emerging hardwares. Future-proofed responsive frontends backed by versatile APIs and real-time asset delivery paves the path for next-generation multi-platform 3 Patti gameplay.
Enhanced User Interactivity Through Gesture Controls
Gesture control gaming employs smartphone/tablet cameras to translate physical motions into game actions intuitively. Integrating this technology with 3 Patti games can make the card-playing experience more immersive. Users can interact by manipulating virtual cards and chips using hand motions instead of buttons. Gesture input future-proofs more engaging play. Companies can also experiment with gland tracking and facial emotion analysis to enable more natural interactions.
The possibilities abound for innovative control mechanisms that boost interactivity. Handheld motion controllers, haptics and biometrics can transport users into game environments in unprecedented ways. Teen patti developers should offer players the flexibility to customize interactions aligned with comfort levels. Defaults use simple touch while advanced modes support controllers or mid-air gestures with greater challenges. Catering interactions to wider needs and accessibilities will maximize engagement. Vocal inputs are another emerging channel – players can speak combinations or negotiate via chatbots in native languages. Play it forward tools even enable passing gestures to other users. Ultimately, control personalization unlocks the next level of immersion.
Immersive Experiences with Augmented Reality (AR)
Developers should integrate nascent technologies like AR and VR to make 3 Patti games more cutting-edge and visually appealing. AR overlays digital imagery onto real-world settings using smartphones and VR headsets offer wholly simulated environments for truly immersive play. These breakthroughs promise extremely engaging future multiplayer experiences beyond limits of physical rooms/tables. Developers can enable players to visually inspect opponents' tells and expressions for strategic play.
AR transforms any real-world setting into a gaming environment using devices players already own. Teen patti companies can initially experiment with social features like displaying player profiles when scanning others at the table. Overlaying environment themes offers customization too. Soon refined computer vision techniques will permit photorealistic card rendering atop surfaces for virtual gameplay replicated anywhere. As extended reality hardware and algorithms advance, replicating the intimacy of physical proximity with accurate eye contacts and micro-expressions in virtual spaces becomes attainable - raising immersion dramatically. The technology is primed to mimic reality itself. Rather than altogether simulated environments, meaningfully augmenting actual reality represents the bigger opportunity.
Artificial Intelligence (AI) for Personalization
Incorporating AI-enabled bots with distinct playing styles provides the illusion of competing against human gamers. Smart bots also facilitate matchmaking based on skill levels. Integrating AI-powered adaptive learning helps generate personalized gaming experiences catered to style/strength areas of individual players—future-proofing enjoyment. As AI models mature, developers can enable automated virtual assistants to provide context-specific advice to human players during games.
The opportunities abound for AI integration throughout the gaming stack. Machine learning algorithms can continuously tailor gameplay by analyzing user behavior – tweaking factors like difficulty adjustment behind the scenes to sustain motivation. Chatbots enrich community engagement on forums where human moderation is infeasible. Generative deep learning further enables automatically compiling game tutorials based on common pain points. In the future, predictive analytics will likely transform gameplay itself – anticipating optimal moves or advising losing players on datadriven strategies to improve competitive enjoyment. The overarching benefit of AI is releasing human creativity from technical constraints – developers can focus on crafting creative game designs rather than manual operational tuning.
Real-Time Multiplayer Experiences
Network capabilities now enable smooth real-time online 3 Patti gameplay against players worldwide through synchronous card dealing and chip exchanges layered on peer-to-peer connectivity. Eliminating lag enables groups to interact seamlessly just as with physical tables. Multiplayer experiences represent the next generation advancement from solitary play. Maintaining robust networks with global server backups guarantees 24/7 access to platforms enabling the social experience expected from card games.
Real-time multiplayer gameplay heightens enjoyment and retention for social players. Teen patti companies can look beyond just facilitating card table interactions to enriching metagame community elements. Leaderboards, guilds and tournament brackets structured as mini social networks layered atop core games leverages multiplayer capabilities fully. Avatar profiles, emotes for expression and chat channels strengthen bonds. Friend recommendation engines apply collaborative filtering to connect players with compatible play styles. Offering diverse multiplayer formats like collaborative team games widens appeal. Competitive gameplay unlocks opportunities for spectating, replay sharing and even esports commentary broadcasts.
Cloud Gaming: The Accessibility of Future of 3 Patti games
Cloud gaming utilizes powerful remote servers to stream high-fidelity games directly onto smartphones/lightweight devices without hardware constraints. By adopting cloud-native architectures, teen patti companies can enable instant play from any device. Cloud solutions also permit scaling to support rising users. Teen patti developers can leverage cloud technology to rapidly test updates with real-user data before deploying to live environments.
In-App Purchase Innovations
Developers explore alternative pricing models beyond one-time purchases/ad-supported games, including multi-tiered subscription packs and in-game NFT auctions offering updated monetization avenues. Enabling diverse pricing strategies future-proofs revenue streams. Companies can also integrate cryptocurrency micropayments and user reward systems to incentivize engagement.
Monetization innovation must balance revenue goals with gameplay integrity to prevent resentment. Teen patti developers of a teen patti development company can structure tiered purchases ethically – basic tiers enable competitive play while upper tiers provide cosmetic enhancements without infringing fairness. Limited-supply of rare virtual goods linked to players’ profiles taps demand for self-expression. Offering free entry tournaments with paid entry to premium tourneys accommodates various budgets. Free trial periods before subscriptions increase conversions. Importantly, purchases should heighten enjoyment rather than conceal content behind paywalls unless opting out entirely. If monetization enhances experiences for all rather than limiting access, it builds goodwill and organic engagement fueling sustainable revenues.
Continuous Updates and Iterations
Besides integrating innovations, developers must fix bugs rapidly, refine UX elements and enhance performance through regular app upgrades. Swiftly incorporating user feedback and testing innovations primes 3 Patti offerings to leverage gaming technology trends shaping market appetites. Developers should implement continuous development workflows to reliably release improvements in a sustainable cadence.

Since its launch in 2016 by Facebook, CRA was seen as the holy grail for easily setting up Webpack, Babel, and other essential tools. But as with anything in the tech world, time has not been kind to CRA. With start-up times stretching and sluggish refreshes, I quickly realized that this old recipe no longer met the needs for rapid and agile development.

Indeed, I noticed that the developer community, which I am a part of, was unanimously crying out for more speed and efficiency. Faced with these growing complaints, I discovered a modern gem: **Vite.js**. Created in 2020 by Evan You (yes, the genius behind Vue.js), Vite was a revelation for me. Its approach of transforming modules on the fly meant I could say goodbye to startup delays and hello to blazing-fast development.
**Vite.js** is not just a new favorite among development tools; it's a revolution. By using ESM (ES Modules) directly in browsers, Vite only loads what's needed, when it's needed. This efficiency is a breath of fresh air, transforming my development experience into a dance rather than a struggle.
For those ready to take the plunge, here’s how I start a React project with Vite. It just takes a few command lines:
```bash
npm create vite@latest my-new-react-project --template react
```
Then, I dive into the project folder and kick off the development server:
```bash
cd my-new-react-project
npm install
npm run dev
```
This simplicity is precisely what I love about Vite.
Here are three reasons why I think you should consider Vite for your React projects:
1. **Uncompromising Performance**: Loading times are minimized thanks to the smart module loading strategy, allowing me to see changes in real time without delay.
2. **Disconcerting Ease**: Goodbye complicated configurations. Most of the time, Vite works wonderfully right out of the box, leaving me more time to code instead of configure.
3. **Future-Ready**: Vite embraces the latest technologies and web standards, ensuring that my projects are always cutting-edge.
In conclusion, choosing Vite.js has redefined how I work with React. It's fast, it's fresh, and it lets me focus on what I love most: creating exceptional applications. Why settle for less?

1,866,134 | Reimagining Design Elements for the Future | No other field has evolved as rapidly as design. Constantly reinventing, reshaping, and adapting to... | 0 | 2024-05-27T04:23:13 | https://www.peppersquare.com/blog/reimagining-design-elements-for-the-future/ | No other field has evolved as rapidly as design. Constantly reinventing, reshaping, and adapting to emerging trends and consumer habits, designers are probably the first to match the latest in the game.
However, this dynamic landscape also compels them to stay relevant quickly. It can be a challenge for designers.
What happens to the traditional design elements, then? Do we discard them entirely to stay current? Or do we build upon them?
## Communicating with design
Design is a form of communication and will continue to remain so. It is, in essence, an effective way to channel a message – through layouts, logos, colors, or even typography. Design is fundamentally connected to technology; hence change is inevitable.
The rise of digital transformation has further led to designs that can connect instantly with audiences. While design elements undergo several changes, some have remained the same. Essential design elements such as lines, form, color, and function still serve as the [foundation for designers.](https://www.peppersquare.com/xperience/the-principles-and-laws-of-ux-design/)
But the evolving consumer needs and behaviours require re-evaluation and adjustments. The question remains, to what extent? Let’s explore:
## Simple and minimalist
Designers have more freedom to make bolder choices now. As users began to scroll more and read less, the minimalist approach toward design became necessary. Consumers and businesses want a cleaner, more responsive design across platforms.
Flat design elements have replaced skeuomorphic design elements like textures and drop shadows. Moreover, the flat design enables designers to create UIs that can be [optimised for mobile devices.](https://www.peppersquare.com/blog/a-guide-to-mobile-app-ui-designs/)
For example, Medium.com has used white spaces to ensure the site is not text-heavy. A blogging platform like Medium is high on content and imagery. But, the look and feel of the UI design are easy to read and use because of its clear organisation, bold headings, and readability.
## Font efficacy
Variable fonts have allowed designers to adjust a font’s properties in real-time and create dynamic typography palettes. It also offers benefits like reduced file size and better performance on the web.
Tech giants like Adobe and Apple use variable fonts because they suit all screen types. Though variable fonts are used for digital design, the future might also see them in print.
## Impactful communication
Design elements have become about being simple yet immersive and creating an impact. Every element needs to have a meaning. While contemporary designs allow designers the flexibility to innovate, they do need to tell a story.
Effective communication remains the basic tenet of any good design. Design elements facilitate easy understanding, retain audiences on the page, and tell a story. Despite design elements and the latest trends engulfing the market, clarity, and functionality are the primary objectives of a good design.
Spotify has been at the forefront of creating an [interactive user experience](https://www.peppersquare.com/blog/understanding-the-ux-of-music-streaming-apps/) that generates interest beyond music. It is comprehensive information about the artists and the genres they are known for. It generates more interest as well as engagement among users.
## Gradient color schemes
Designers know how powerful colors are in impacting people’s minds. Despite technological advancements, colors and their significance play a critical role in design. Technology has further accentuated their importance.
The future of design might see more color transitions and duotones that add more depth, visuals, and modern touch to designs, providing impactful visual experiences. It will also depend a lot on the cultural and political shifts of the times.
## Integration of AI
The future will likely be AI-driven, and designers might need to go the AI way. The good news is that [designers will benefit from AI](https://www.peppersquare.com/blog/can-ai-be-your-next-ui-ux-designer/) and can use it to streamline their workflow. As designs evolve and the creative landscape changes, designers should maintain sight of their designs’ purpose.
Effective communication and an interactive approach are the end goals for designers. While experimenting with new strategies and techniques, designers should keep the user experience in mind.
A perfect example of the above is Canva. While Canva is not a replacement for designers (as is often believed), it offers a wide range of templates. Its AI-powered design tools suggest fonts, colors, and layouts that help create an aesthetic and cohesive design.
## Hierarchy and composition
As attention spans reduce across digital platforms, designers focus on the arrangement of elements and a cohesive layout. These factors play an essential role in guiding and retaining user attention. Visual balance and an organised layout are effective communication tools across digital and communication channels.
From magazines to websites and mobile apps, designers continue to work on positioning elements and creating visually appealing layouts that provide value.
## Innovation
There’s no denying that innovation is a crucial part of design. No matter the product or service, designers need to innovate continuously. The goal is to prevent decision fatigue and make the design compelling enough to stay in people’s minds.
With users moving from site to site within seconds, designers are developing new ways to enhance discoverability and functionality. Uber, for example, added a new feature to their app wherein users can get real-time updates about their ride – arrival, pin, arrival time – on their lock screen. It allows for easy navigation as well as efficiency for users.
## Personalised approach
Technology has enabled a greater scope for a customised approach to designing. Designers have already begun to infuse [personalised elements](https://www.peppersquare.com/ui-development/) in their designs to meet individual needs.
It requires designers to incorporate custom options and adapt to individual user needs. Personalised interfaces, recommendations, and adaptive layouts can enhance user experience based on their behaviour patterns and preferences.
Airbnb uses a cohesive, personalised approach to analyse what users might look for in a new place. Their recommendations are not limited to accommodations but include sightseeing, restaurants, and social gatherings. The minimalist design allows users to look for precisely what they want.
**<u>Conclusion</u>**
The evolution of design elements is an opportunity to keep innovating and adding more to the overall user experience. A lot of it has begun already. For example, designers integrate dynamic and interactive elements to improve user engagement.
The goal is to prevent users from dropping off soon by creating more immersive experiences. Motion graphics and animation have already seeped into the user psyche. The future might see a lot of augmented reality (AR), virtual reality (VR), and mixed reality (MR) elements that take user interactions several steps ahead.
These are but a few predictions based on what we see today. The future of design elements is subject to continuous change. Many of these elements also change depending on users’ expectations as technology advances.
It’s up to designers to push boundaries, experiment, and reinvent themselves to keep in tune with the times.

1,866,130 | Switching to Vite from React-Scripts | I have a silly react project that I’m working on that I made using create-react-app. By default,... | 0 | 2024-05-27T04:19:34 | https://bryanliao.dev/blog/switching-to-vite-from-react-scripts/ | webdev, javascript, react, vite |
I have a silly react project that I’m working on that I made using [create-react-app](https://create-react-app.dev/). By default, these kinds of projects build and run using [react-scripts](https://github.com/facebook/create-react-app/tree/main/packages/react-scripts) which uses webpack [under the hood](https://github.com/facebook/create-react-app/blob/main/packages/react-scripts/scripts/build.js) for building projects. [Vite](https://vitejs.dev/) is generally known to be faster than Webpack ⚡ so I was curious about how to swap them.
Installation is simple enough, there’s two dev dependency modules that need to be included:
[Vite](https://www.npmjs.com/package/vite) and [Vite’s React Plugin](https://www.npmjs.com/package/@vitejs/plugin-react)
To utilize Vite, start by creating a `vite.config.js` file. Here’s a very basic example of what I added:
```jsx
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
export default defineConfig({
plugins: [react()].
root: 'src',
});
```
Since Vite uses `index.html` as the entry point for the application, I moved it out of my `public` folder and into my `src` folder. I removed the `%PUBLIC_URL%` part from my HTML file and added a script to point to where my react root was created:
`<script type='module' src='./index.tsx'></script>`
All that’s left is to replace the scripts in `package.json` to use [vite commands](https://vitejs.dev/guide/cli.html) instead and remove `react-scripts` as a dependency. 🎉 | liaob |

TypeScript is a... | 0 | 2024-05-27T04:03:01 | https://dev.to/allyn/step-into-typescript-part-1-10dg | typescript, webdev, beginners | Continuing my exploration of JavaScript has led me into the world of TypeScript. TypeScript is a free, open-source, typed programming language that is a superset of JavaScript.
TypeScript was released in October 2012 with version 0.8 and developed by Microsoft. A superset of JavaScript, TypeScript knows JavaScript and adds additional syntax to make a more fortified application. Also, being built on JavaScript, TypeScript can be transpiled into JavaScript and perform type inference so you do not have to add any additional code. Type inference is defined as "the ability to deduce, either partially or fully automatically, the type of an expression at compile time," with 'type' referring to data types (i.e. 'string', 'number', etc.).
TypeScript focuses highly on data types, hence the name and enhanced syntax and features we will go over. One of these features is defining types with interface declaration. Interfaces, in TypeScript, act as contracts that enforce consistent assignment of types. Interface declaration can be compared to JavaScript's subclassing, in the sense that you establish the structure and/or type of something. All of your JavaScript code will not always be inferred, so you use interfaces to ensure that TypeScript knows what values are to be expected. Let's take a look at an example.
[These examples are provided by TypeScript's documentation.](https://www.typescriptlang.org/docs/handbook/typescript-in-5-minutes.html)
```
const user = {
name: "Allyn",
id: 0,
};
```
Here we have an object called `user` that has properties of `name` and `id`. The properties of `name` and `id` can be inferred as a string and number respectively, but there's a way to enforce that these properties are consistently strings and numbers.
```
interface User {
name: string;
id: number;
}
```
By using interface declaration, you can ensure that `name` will always be a string and `id` a number. Think of this `User` interface as a blueprint for `user` objects. To make sure that JavaScript follows this blueprint, we create an 'instance' of a type by adding `: TypeName` in between the variable name and the assignment operator.
```
const user: User = {
name: "Allyn",
id: 0,
};
```
From a JavaScript perspective, this is comparable to subclassing. In fact, you can use interface declaration for classes too, since both JavaScript and TypeScript support classes.
TypeScript can use primitive JavaScript data types in interfaces, which include: booleans, null, and undefined. TypeScript adds to this list with types like `any`, `never`, and `void`. The `any` type is to signify that there aren't any restrictions to what type can be assigned, the `never` type is to determine what type will never be assigned, and the `void` type is used for having no type at all, undefined, and is commonly used in the context of function return values.
Out of the box, TypeScript uses primitive data types, but what about complex data types such as collections? Fortunately, TypeScript allows you to create your own type. The 2 most popular ways to create types are with unions, which can be recognized with a pipe `|`, or with generics, following this syntax: `<variable>`.
Unions can be used when a type can be one out of many types and are commonly used for defining options out of a set. In this example, `color` can be one out of many colors, and `spice` can be one of many numbers.
```
const ColorOptions = "green" | "yellow" | "pink" | "black";
const SpiceOptions = 1 | 3 | 5 | 7;
```
Generics act as variables for types and are commonly used to describe what type an array contains. For example, this `NamesArray` will consist of strings. Take note of the `type` keyword that creates an alias for the type. In this case, `NamesArray` is the alias for the array type.
```
type NamesArray = Array<string>;
```
In this example, [provided by the TypeScript documentation](https://www.typescriptlang.org/docs/handbook/typescript-in-5-minutes.html#generics), you can use generics in conjunction with interfaces to create types that have a predetermined consistency.
```
interface Backpack<Type> {
add: (obj: Type) => void;
get: () => Type;
}
// This line is a shortcut to tell TypeScript there is a
// constant called `backpack`, and to not worry about where it came from.
declare const backpack: Backpack<string>;
const object = backpack.get();
```
Let's go through this code line by line. We start off by creating a backpack interface that consists of 2 methods: add and get, both refer to the `Type` variable that will be filled in later when the interface gets used. Next, our `backpack` variable gets 'string' passed in, meaning the `obj` is a string and the `get` method returns a string since both refer to the `Type` variable.
From what we've gone over, we can see how essential data types are for TypeScript. We can see that the syntax follows closely to JavaScript but the use of the language shifts to hone on consistency and avoiding errors. In my next post, I will go over the Structural Type System, Classes, and how TypeScript can be compared to JavaScript.

Welcome back to my blog where I document the things I learned in web development. I do this because it helps retain the information and concepts as it is some sort of an active recall.
On days 21-23, I built a palindrome checker, a music player, and a date formatter to learn basic string, array methods, date objects, and to complete part 1 of the Data Structures & Algorithms certification project.
4 things I learned:
1. Using a spread syntax (e.g. `[…arrayName]`) to call an entire array.
2. To use arrow function/callback function (e.g. `const variableName = (parameter) => {logic;}` or `()=>{}`)
3. Chaining multiple methods together (e.g. `variableName.method1().method2().method3()`);
4. Optional chaining to prevent errors when accessing nested properties that might be null or undefined. (e.g. `arrayName?.array[]`)
I finished part 1 of the Data Structures & Algorithms certification project. Because of that, I was finally able to connect together the concepts of variables, linking DOM elements, functions, and if-else statements. It’s so freaking good to feel a sense of progress by understanding the syntaxes I used in building the palindrome checker.
However, I feel like I need more time and practice with freecodecamp’s coding challenges and keep moving forward with the course. You know what they say, more practice leads to more experience and more experience = more learnings.
Anyways, that’s all for now, thank you for reading. I’ll see you all next blog! | thomascansino |

1,865,689 | Recipe App submission for AWS Amplify Fullstack Typescript Challenge | This is a submission for the The AWS Amplify Fullstack TypeScript Challenge * I am proud to submit... | 0 | 2024-05-27T03:54:03 | https://dev.to/katvengo/recipe-app-submission-for-aws-amplify-fullstack-typescript-challenge-2p4g | devchallenge, awschallenge, amplify, fullstack | This is a submission for the [The AWS Amplify Fullstack TypeScript Challenge ](https://dev.to/challenges/awschallenge)*
I am proud to submit my first ever DEV challenge entry! As a busy mom, this was a challenging but enjoying week+ where I got to combine my two favorite passions - coding and cooking. I have previously before tried to build applications using AWS Amplify but never got a chance to get one deployed. For this challenge, I built a recipe app with AWS Amplify that lets a user create a new profile, login, create a recipe and have those recipes display on the users personal page.
## Demo and Code
[Here](https://master.dnza87n9su44c.amplifyapp.com/) is the AWS Amplify Link to the live site
The source code can be found on [GitHub](https://github.com/katvengo/recipe-app/tree/master/frontend)
Here are some images taking you thru the flow of the app.
## Integrations
**AWS Cognito
**
For Application authentication I integrated AWS Cognito and the Amplify UI Authenticator into the app which handles creating the user, sending a confirmation email and sign in. I customized the authentication in two ways.
First, I added a user attribute property when defining my authentication that allows a user to enter a preferred username.
Second, in order to tie users to their recipes I created a post confirmation trigger when the user confirms the account.
**AWS Data
**
To manage CRUD operations for recipes and the user profile I integrated AWS Data which let me define my data models then use those same models to read the data from the client. One of the challenges I faced was in trying to read the User Profile information which was tied to the user authenticating with Cognito. I wanted to be able to have a user login, then grab details like username and recipes. In the original tutorial to create a user profile a profileOwner is created with the sub or username. However, I was unable to get that specific user with the profileOwner. I ended up tweaking the confirmation trigger which created the user profile using graphql and created two input variables of email and originally profileOwner. I was able to change profileOwner to id and add other attributes to my user profile and that solved the issue.
**AWS Lambda Function
**
As previously mentioned this was used to trigger the post confirmation create user profile.
**Connected Components and/or Feature Full**
This application uses AWS for data, authentication and a serverless function. In addition, since I was already using the AWS UI authenticator component, it became easy to integrate the rest of AWS components into my app.
Thank you for reading! I learned so much from this experience and would be happy to go into more detail or answer any questions for you if you're working on your own AWS Amplify app.

In this article I plan to go over just a few of the strengths and advantages that the Elixir programming language has to offer. Applications today often have issues with scaling and concurrency and Elixir provides that solution. Large-scale sites and applications that you may be familiar with, such as Discord, Pinterest, and even PepsiCo, utilize these advantages.
### What is Elixir?
Elixir is a robust, functional programming language, inspired by Ruby, excelling in Fault-tolerance capabilities, Scalability, and Concurrency, focusing on productivity and readability. Elixir prioritizes pure functions, higher-order functions, and immutable data, encouraging expressive, clear code writing. I mention robustness due to Elixir's utilization of a functional approach which provides clear, concise code, reduction of bugs, and upon
troubleshooting or debugging the problems are solved in small, testable units. Considering functions are treated as primary elements, or first-class entities, they are passed as arguments to other functions or returned as a result allowing strong composition and abstractions.
## <u>Strengths</u>
Erlang's goal is to provide the ability to create highly available systems that run consistently and provide meaningful responses to client requests. But in order to achieve a highly available system you have to overcome fault tolerance, scalability, and distribution so that the provided service has minimal failures as well as downtime.
[Elixir-in-action](https://livebook.manning.com/book/elixir-in-action-third-edition/chapter-5/5#:~:text=Fault%20tolerance%E2%80%94Minimize,one%20machine%20crashes.)
- Fault tolerance: Minimize, isolate, and recover from the effects of run-time errors.
- Scalability: Handle a load increase by adding more hardware resources without changing or redeploying the code.
- Distribution: Run your system on multiple machines so that others can take over if one machine crashes.
### Concurrency
> [Elixir](https://erlang-solutions.com/blog/what-is-elixir/#:~:text=Understanding%20functional%20programming%20in%20Elixir,-In%20Elixir%2C%20functional&text=Elixir's%20functional%20programming%20paradigm%20supports,creating%20distributed%20and%20concurrent%20applications.)’s processes communicate asynchronously.
> Concurrent operations are efficient and responsive.
Elixir is a concurrent language as well as a functional language. The concurrent characteristic allows you to improve the availability of your system and organize your runtime, whereas the functional portion allows clean and organized code. One of the major benefits to using Elixir is it's support for concurrency and thanks to Erlang's virtual machine ([BEAM](https://www.erlang-solutions.com/blog/erlangs-virtual-machine-the-beam/)), and it's tools and techniques, this has been a central role in doing so.
### Scalability
> [Elixir](https://erlang-solutions.com/blog/what-is-elixir/#:~:text=Understanding%20functional%20programming%20in%20Elixir,-In%20Elixir%2C%20functional&text=Elixir's%20functional%20programming%20paradigm%20supports,creating%20distributed%20and%20concurrent%20applications.)’s lightweight processes enable easy concurrency.
Scalability and concurrency is essential for Applications we use and build today. Elixir allows us to build applications where performance isn't compromised when dealing with large quantities of requests. Additionally, the distributed environment that Elixir provides allows applications to scale horizontally which is perfect for indulging rapid growth in businesses. Elixir's concurrency model gives developers access to create lightweight processes, called Actors, that communicate seamlessly with other processes via passing messages. And with that level of communication systems can scale over multiple nodes with ease.
### Fault-Tolerance
Within [BEAM](https://www.erlang-solutions.com/blog/erlangs-virtual-machine-the-beam/), fault tolerance is a first-class concept that gives the ability to develop reliable systems. The ultimate concept of fault tolerance is to recognize failures while diminishing their impacts upon a system and it to recover without human interference. Now it's not to say that failures or bugs won't happen. In any complex system things can certainly go awry, whether it's hardware, components, bugs, or even the inability to cope with a large request rate. Luckily the failures that do occur are isolated and then managed to ensure that the system continues running, hence Erlang's philosophy of 'let it crash'.
<u>_Supervision Trees_</u>
A supervision tree is a hierarchical structure that contains a list of child processes it will manage using Supervisors. Supervisors are specialized processes that monitor other processes to ensure system resilience by forcing child processes to automatically restart when they happen to fail. The capabilities of managing the children processes are defined within the strategies you desire the supervisor to use. Currently there are three supervision strategies that supervisors have available to them.
`one_for_one` - Restart only the child process that terminated
`one_for_all` - In the event of a failure, restart all of the child processes.
`rest_for_one` - Restart the process that failed as well as any process that was started after it.
This is an example of what a Supervisor Tree would look like:
```
def start(_type, _args) do
children = [
worker(:root_worker),
supervisor(
:one_for_one,
[
worker(:worker_1),
worker(:worker_2)
],
name: :supervisor_1
),
supervisor(
:rest_for_one,
[
worker(:worker_3),
worker(:worker_4),
worker(:worker_5),
supervisor(
:one_for_one,
[worker(:subworker_1)],
name: :subsupervisor_1
)
],
name: :supervisor_2
),
supervisor(
:one_for_all,
[
worker(:worker_6),
worker(:worker_7),
worker(:worker_8)
],
name: :supervisor_3
),
worker(:transient_root_worker, :transient)
]
# The root of the tree is a supervisor that runs everything we defined above
opts = [strategy: :one_for_one, name: SupervisorSample.Supervisor]
Supervisor.start_link(children, opts)
end
```
## Conclusion
I am still in the early stages of my software developer journey and I am always fascinated when it comes to learning new items the software world has to offer and Elixir has made it's way up into my list of next languages I'd like to learn in it's entirety. I hope this short introduction to some of Elixir's strengths intrigued you as much as it did me. I plan to continue my research with Elixir and Erlang and provide more information for those that are also interested in working with it.

1,860,709 | Database Migration: Take Care of Your Database Changes | Preamble Database Migration is basically a process that should be initialized and started... | 0 | 2024-05-27T03:47:38 | https://dev.to/nghtslvr/database-migration-take-care-of-your-database-changes-11e6 | database, tutorial, go, architecture | ### Preamble
Database Migration is basically a process that should be initialized and started before starting up a service that need database. In this moment I would share my experience about Database Migration, that helps me for moving or duplicating a database which already good to go.
I will show you how to create an simple program for performing database migration using [Golang Migrate](https://github.com/golang-migrate/migrate). Before we proceed to next step make sure you already install its binary on your system, here is the release list with various operating system option, [Golang Migrate Releases](https://github.com/golang-migrate/migrate/releases).
By creating this program, you can easily setup database design and its sample data. And I have repository you can clone for this [here is it](https://github.com/xoxoist/dm-tutor), while reading this post you will understanding how it works. And I recommend you to have docker installed in your pocket for this tutorial.
---
### Database Migration Directory
I already have the repository for this one, inside the project there is package named `database` and inside it there is `migration` package where you put all generated migration files. Here is the structure of it.
---
### Database Server Setup
For this moment you need to run mysql database server in your machine, if you are already have installed one, you can just go with it. If you want to use docker here is the command to spin up mysql server in simple way.
```bash
run -d -p 3306:3306 --name mysql-db -e MYSQL_ROOT_PASSWORD=root mysql:5.7.44
```
---
### Install golang-migrate
To install golang-migrate you can choose which operating system did you use. Extract `migrate` binary file and register it your environment path. You can download `migrate` from its releases page [golang migrate download](https://github.com/golang-migrate/migrate/releases/tag/v4.17.1).
---
### Generate Migration Files
Once already download `migrate` binary file and register it to your environment path, you can check it by running this command.
```bash
migrate --version
```
It will show you which `migrate` version did you use.
For generate migration files you can use this command
```bash
migrate create -ext sql -dir path/to/migration/dir -seq migration_file_name
```
Explanation
- `-ext` This arg is to tell `migrate` to use `sql` extension
- `-dir` This arg is to tell `migrate` where migration files at
- `-seq` This arg is to tell `migrate` to use sequential numbering for every migration file you generate this is the sample `000001_create_users_table.up.sql` and `000001_create_users_table.down.sql`
And we need to generate 2 migration files each of it will be have `up` and `down` version. So there will be 4 files. Let's generate migration file for `users` and `profiles` table. And make sure your current working directory is on the root of the project.
```bash
migrate create -ext sql -dir database/migration -seq create_users_table
migrate create -ext sql -dir database/migration -seq create_profiles_table
```
When you take a look in the project it will be looks like this
What is difference between `up` and `down` migration file?
- `up` This migration file will does construction for your database
- `down` This migration file will does deconstruction for your database
Or can be simplified `up` migration file will contains creation and modification action. In the other hand `down` will contains drop or removal action.
---
And here is the SQL Query that will performed when migration process running.
#### Users Table Migration Files
#### `000001_create_users_table.up.sql`
```sql
CREATE TABLE users
(
id SERIAL PRIMARY KEY, -- Auto-incremented primary key
email VARCHAR(255) NOT NULL UNIQUE, -- Email column with unique constraint
password VARCHAR(255) NOT NULL, -- Password column
username VARCHAR(50) NOT NULL UNIQUE, -- Username column with unique constraint
deleted_at TIMESTAMP NULL, -- Timestamp for soft deletion
updated_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP, -- Timestamp for last update
created_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP -- Timestamp for creation
);
-- Adding index for columns that might be frequently searched or filtered
CREATE INDEX idx_users_email ON users (email);
CREATE INDEX idx_users_username ON users (username);
-- Index for deleted_at to quickly filter non-deleted users
CREATE INDEX idx_users_deleted_at ON users (deleted_at);
```
#### `000001_create_users_table.down.sql`
```sql
DROP TABLE users;
```
#### Profiles Table Migration Files
#### `000001_create_profiles_table.up.sql`
```sql
CREATE TABLE profiles
(
id SERIAL PRIMARY KEY, -- Auto-incremented primary key
user_id INTEGER NOT NULL, -- Assuming user_id will link to users table but without any constraint
first_name VARCHAR(50) NOT NULL, -- First name of the user
last_name VARCHAR(50) NOT NULL, -- Last name of the user
bio TEXT, -- A short bio of the user
profile_picture VARCHAR(255), -- URL to the profile picture
deleted_at TIMESTAMP NULL, -- Timestamp for soft deletion
created_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP, -- Timestamp for creation
updated_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP -- Timestamp for last update
);
-- Adding index for columns that might be frequently searched or filtered
CREATE INDEX idx_profiles_user_id ON profiles (user_id);
CREATE INDEX idx_profiles_last_name ON profiles (last_name);
```
#### `000001_create_profiles_table.down.sql`
```sql
DROP TABLE profiles;
```
---
### Implementation
In this section we jump to coding and how to use as it Standalone Program or Embedded routine inside your application. Inside repository project there are 3 golang file for database migration `connector.go`, `mlog.go` and `migration.go`.
#### `connector.go`
In this file you can add your own database connection function template for your desired database by copy paste existing sample and adjust based on your need. In this sample will be 2 MySQL and Postgres.
```go
package database
import (
"database/sql"
"fmt"
"github.com/golang-migrate/migrate/v4"
"github.com/golang-migrate/migrate/v4/database/mysql"
"github.com/golang-migrate/migrate/v4/database/postgres"
)
// connect database connector using builtin go sql library
func connect(dialect, connStr string) (*sql.DB, error) {
db, err := sql.Open(dialect, connStr)
if err != nil {
return nil, err
}
err = db.Ping()
if err != nil {
return nil, err
}
return db, nil
}
// MySQLBuilder decorator function for constructing mysql connection string
func MySQLBuilder(cfg Config) (*migrate.Migrate, error) {
// construct connection string and connect
const formatString = "%s:%s@tcp(%s:%s)/%s?parseTime=true&multiStatements=true"
credentials := []any{
cfg.DatabaseUser, cfg.DatabasePasw, cfg.DatabaseHost,
cfg.DatabasePort, cfg.DatabaseName,
}
finalCsf := fmt.Sprintf(formatString, credentials...)
db, err := connect("mysql", finalCsf)
if err != nil {
return nil, err
}
// create migrate instance from connected database client
driver, err := mysql.WithInstance(db, &mysql.Config{})
if err != nil {
return nil, err
}
filePath := fmt.Sprintf("file://%s", cfg.DatabaseMdir)
mgrt, err := migrate.NewWithDatabaseInstance(filePath, cfg.DatabaseDrvr, driver)
if err != nil {
return nil, err
}
return mgrt, nil
}
// PostgresBuilder decorator function for constructing mysql connection string
func PostgresBuilder(cfg Config) (*migrate.Migrate, error) {
// construct connection string and connect
const formatString = "postgres://%s:%s@%s:%d/%s?sslmode=disable"
credentials := []any{
cfg.DatabaseUser, cfg.DatabasePasw, cfg.DatabaseHost,
cfg.DatabasePort, cfg.DatabaseName,
}
finalCsf := fmt.Sprintf(formatString, credentials...)
db, err := connect("postgres", finalCsf)
if err != nil {
return nil, err
}
// create migrate instance from connected database client
driver, err := postgres.WithInstance(db, &postgres.Config{})
if err != nil {
return nil, err
}
filePath := fmt.Sprintf("file://%s", cfg.DatabaseMdir)
mgrt, err := migrate.NewWithDatabaseInstance(filePath, cfg.DatabaseDrvr, driver)
if err != nil {
return nil, err
}
return mgrt, nil
}
```
#### `mlog.go`
This file contains logger implementation for `migrate` to log execution process. This log will be used inside `migration.go` file.
```go
package database
import "log"
type (
Log interface {
Printf(format string, v ...interface{})
Verbose() bool
}
// logImpl implements the golang-migrate Logger interface
logImpl struct {
logger *log.Logger
}
)
func NewLog(logger *log.Logger) Log {
return &logImpl{logger: logger}
}
func (l *logImpl) Printf(format string, v ...interface{}) {
l.logger.Printf(format, v...)
}
func (l *logImpl) Verbose() bool {
return true // or false, depending on whether you want verbose logging
}
```
#### `migration.go`
This file contains logger implementation for `migrate` to log execution process. This log will be used inside `migration.go` file.
```go
package database
import (
"errors"
_ "github.com/go-sql-driver/mysql"
"github.com/golang-migrate/migrate/v4"
_ "github.com/golang-migrate/migrate/v4"
_ "github.com/golang-migrate/migrate/v4/database/mysql"
_ "github.com/golang-migrate/migrate/v4/database/postgres"
_ "github.com/golang-migrate/migrate/v4/source/file"
_ "github.com/lib/pq"
"log"
)
type (
// ConnectionFunc decorator function for constructing connection string
ConnectionFunc func(cfg Config) (*migrate.Migrate, error)
// Config database configuration detail for connecting to desired database server
Config struct {
DatabaseHost string // database host
DatabasePort string // database port
DatabaseName string // database name
DatabaseUser string // database user
DatabasePasw string // database password
DatabaseDrvr string // database driver
DatabaseMdir string // database migration dir
}
// Migration interface for migration
Migration interface {
Action(name string) error
down() error
up() error
}
// migrationImpl implementation struct
migrationImpl struct {
m *migrate.Migrate
}
)
func NewMigration(cf ConnectionFunc, cfg Config) (Migration, error) {
// initialize migration instance
m, err := cf(cfg)
if err != nil {
return nil, err
}
m.Log = NewLog(
log.New(log.Writer(),
"migration: ",
log.LstdFlags|log.Lshortfile,
),
)
mg := &migrationImpl{m: m}
return mg, nil
}
// Action migrating desired migration version start constructing database
func (mgr *migrationImpl) Action(name string) error {
mgr.m.Log.Printf("migaration.Action: %s", "starting to constructing database")
switch name {
case "UP":
return mgr.up()
case "DOWN":
return mgr.down()
default:
mgr.m.Log.Printf("migaration.Action: %s (%s)", "unknown action name", name)
return errors.New("unknown action")
}
}
// down performing all SQL inside `down` migration files
func (mgr *migrationImpl) down() error {
err := mgr.m.Down()
if err != nil {
if errors.Is(err, migrate.ErrNoChange) {
mgr.m.Log.Printf("migaration.down: %s (%s)", "deconstructing database done", err.Error())
return nil
}
mgr.m.Log.Printf("migaration.down: %s (%s)", "failed to deconstructing database", err.Error())
return err
}
return nil
}
// up performing all SQL inside `up` migration files
func (mgr *migrationImpl) up() error {
mgr.m.Log.Verbose()
err := mgr.m.Up()
if err != nil {
if errors.Is(err, migrate.ErrNoChange) {
mgr.m.Log.Printf("migaration.down: %s (%s)", "constructing database done", err.Error())
return nil
}
mgr.m.Log.Printf("migaration.down: %s (%s)", "failed to constructing database", err.Error())
return err
}
return nil
}
```
### How to Use
We will use `Migration` implementation inside `main.go` file, and I will show you how to use it as Standalone Program or Embeded Routine for your application.
#### Standalone Program
We will compile this into executable binary. Here is the `main.go` content for that.
```go
package main
import (
"flag"
"github.com/xoxoist/dm-tutor/database"
)
func main() {
action := flag.String("action", "UP", "desired action for your database migration")
flag.Parse()
mg, err := database.NewMigration(database.MySQLBuilder, database.Config{
DatabaseHost: "localhost",
DatabasePort: "3306",
DatabaseName: "md_tutor",
DatabaseUser: "root",
DatabasePasw: "root",
DatabaseDrvr: "mysql",
DatabaseMdir: "database/migration",
})
if err != nil {
panic(err)
}
err = mg.Action(*action)
if err != nil {
panic(err)
}
}
```
And let's compile it into executable binary named `migrator`
```bash
go build -o migrator main.go
```
Here is how to use that complied executable binary. And make sure you are on same current working directory with `migrator`
##### UP
```bash
./migrator -action UP
```
Response for UP action
```bash
migration: 2024/05/26 21:19:45 mlog.go:22: migaration.Action: starting database migration
migration: 2024/05/26 21:19:45 mlog.go:22: Start buffering 1/u create_users_table
migration: 2024/05/26 21:19:45 mlog.go:22: Start buffering 2/u create_profiles_table
migration: 2024/05/26 21:19:45 mlog.go:22: Read and execute 1/u create_users_table
migration: 2024/05/26 21:19:45 mlog.go:22: Finished 1/u create_users_table (read 932.759µs, ran 14.400196ms)
migration: 2024/05/26 21:19:45 mlog.go:22: Read and execute 2/u create_profiles_table
migration: 2024/05/26 21:19:45 mlog.go:22: Finished 2/u create_profiles_table (read 16.819281ms, ran 10.786267ms)
```
##### DOWN
```bash
./migrator -action DOWN
```
Response for DOWN action
```bash
migration: 2024/05/26 21:20:07 mlog.go:22: migaration.Action: starting database migration
migration: 2024/05/26 21:20:07 mlog.go:22: Start buffering 2/d create_profiles_table
migration: 2024/05/26 21:20:07 mlog.go:22: Start buffering 1/d create_users_table
migration: 2024/05/26 21:20:07 mlog.go:22: Read and execute 2/d create_profiles_table
migration: 2024/05/26 21:20:07 mlog.go:22: Finished 2/d create_profiles_table (read 28.291992ms, ran 11.132556ms)
migration: 2024/05/26 21:20:07 mlog.go:22: Read and execute 1/d create_users_table
migration: 2024/05/26 21:20:07 mlog.go:22: Finished 1/d create_users_table (read 41.51291ms, ran 8.649414ms)
```
#### Embedded to Application
How to use still remain the same with Standalone Program, but you just need this `err = mg.Action(*action)` into `err = mg.Action("UP")` or `err = mg.Action("DOWN")`. based on your need. and put this code on initialization phase of your application
```go
mg, err := database.NewMigration(database.MySQLBuilder, database.Config{
DatabaseHost: "localhost",
DatabasePort: "3306",
DatabaseName: "md_tutor",
DatabaseUser: "root",
DatabasePasw: "root",
DatabaseDrvr: "mysql",
DatabaseMdir: "database/migration",
})
if err != nil {
panic(err)
}
//err = mg.Action("DOWN")
err = mg.Action("UP")
if err != nil {
panic(err)
}
```
### Behavior
This migration has behavior to be known before you use it. When it started `up` your migration it will execute all your SQL query on your migration files, also automatically create table named `schema_migrations` to track where migration version sequence at, and is it dirty? if dirty it means there is something wrong in your SQL query syntax and need to be fixed before it moves to next version sequence of your migration file. Here is the `schema_migrations` table structure.
Schema Migration Table
Your defined tables inside migration files
For this case current version sequence of your migration files is `2`, try to look column `version`.
When you try to `down` the migration process all table dropped and leave you `schema_migrations` table without any rows.
When there is SQL syntax error while `up` or `down` your migration. You need manually edit `version` to which version sequence before version sequence that has SQL syntax error, and reset `dirty` to `0` again on `schema_migrations` table.
If column `dirty` is `0` means there is no syntax error on your migration files
If column `dirty` is `1` means there is syntax error on your migration files.
---
### Conclusion
Database Migration helps you construct your database design in a complete new environment, and you also could add new table or modify table by generate new migration file and write SQL query for that and re-run the program.
You can also put this program inside your application so when the application start it will runs the migration process and ignore the migration process when there is no changes in migration files.
You have 2 option make this program as standalone program or you can embed it inside your application code.
Its up to you and based on your needs, for my personal I would make it as standalone program, where I can keep track database changes and no distraction from others, so when ever someone need a new changes, I just ask the final query for that changes.
If I embed it inside application, people who contribute in that application development will freely add changes and I think it is not so good, every addition and modification of database structure should be discussed before it applied. So again back to your needs. Make it standalone or embed it inside application.

1,866,105 | Game Development Diary #6 : Weekend | 25/05/2024 - Sunday Today’s Progress: No development work was conducted on the game... | 27,527 | 2024-05-27T03:41:58 | https://dev.to/hizrawandwioka/game-development-diary-6-weekend-25pc | 25/05/2024 - Sunday
# Today’s Progress:
No development work was conducted on the game today.
#Thoughts:
Even though no direct technical work on the game was done today, I read a book called Theory of Fun for Game Design: Edition 2 by Raph Koster.
Here is what I've got from this book :
##Understanding Fun:
Koster examines what makes games fun, suggesting that fun arises from learning, comprehension, and mastery. He proposes that we are evolutionarily programmed to enjoy learning because it has historically improved our chances of survival.
##Learning Patterns:
The book discusses how games teach us through patterns. These patterns can range from calculating odds and predicting events to understanding social power and status. Games become boring when there’s nothing new to learn or when they’re too easy or too difficult.
##Designing for Engagement:
Koster emphasizes the importance of creating games that are engaging, entertaining, and addictive. He presents ideas on how to improve game designs to incorporate a high degree of fun.
##Cultural Influence:
The book also touches on how games serve as powerful learning tools and the influence they have on culture. It encourages designers to think beyond traditional game mechanics and consider the ethical implications of entertainment.

1,866,061 | PSY Factor Upgrade and Transformation | Welcome all traders to my channel, I am a Quant Developer, specializing in full-stack development of... | 0 | 2024-05-27T03:16:15 | https://dev.to/fmzquant/psy-factor-upgrade-and-transformation-36ch | psy, factor, trading, fmzquant | Welcome all traders to my channel, I am a Quant Developer, specializing in full-stack development of CTA, HFT & Arbitrage trading strategies.
Thanks to the FMZ Platform, I will share more content related to quantitative development and work together with all traders to maintain the prosperity of the quant community.
Today, I will bring you an upgrade and transformation of the PSY (Psychological Line) factor. We will show how to add more market information from a simple factor perspective, step by step transform it, and ultimately turn it into a powerful factor with explanatory and logical strength!!! Of course, after reading this article, you can incorporate the transformed PSY factor into your own library of factors as a powerful weapon~
> PART1 Initial PSY Factor
The PSY Factor (Psychological Line) is a technical analysis indicator used to measure the impact of market participants' emotions on price trends. It is an emotional index for studying investors' psychological fluctuations in response to market ups and downs, and it's a type of energy and rise-fall indicator. It has certain reference significance for judging short-term market trends.
The PSY factor was first proposed by Dr. Wang Yawei in 1991. He believed that the psychological changes in the market are closely related to price trends, and quantified these psychological changes into the PSY factor. As an indicator for analyzing market fluctuations, the PSY factor calculates the total bullish and bearish forces within N K-lines over time to describe whether the current market is strong or weak, or if it's in an overbought or oversold state. It mainly measures investors' psychological endurance by calculating how many rising K-lines there are within N K-lines, providing a reference for investors' buying and selling operations.
The PSY factor is based on the number of days the closing price rises or falls over a period of time. Its calculation method is very simple, and the calculation formula is as follows: PSY=(Number of rising days within N K-lines/N)*100. Here, N period represents the selected calculation period, which can be several days, weeks or months etc. The number of rising days refers to the number of trading days with rising prices within the N period. The initial PSY factor function source code based on FMZ platform:
```
function calculatePSY(data, n) {
let count = 0;
for (let i = data.length - n; i < data.length; i++) {
if (data[i] > data[i - 1]) {
count++;
}
}
return (count / n) * 100;
}
// Usage example
let closePrices = [10, 12, 13, 11, 14, 15, 16, 17, 18, 20];
let nPeriod = 5;
let psyFactor = calculatePSY(closePrices, nPeriod);
Log(psyFactor);
```
> PART2 Enhance PSY Factor (PSY+PRICE)
The essence of the PSY factor is a momentum factor, which measures the comparison of the root numbers of rising and falling forces over a period of time, with the aim to find out which side has greater strength in the past. However, upon careful observation, it can be found that the PSY factor only considers whether the BAR line is rising or falling, lacking a description of BAR itself and unable to judge the intensity of market conditions, resulting in situations -- Of the last 6 K-lines, 3 were down and 3 were up, and the value of 50, as constructed by the initial PSY factor, it does not discern the strength of the long and short forces in the last 6 K-lines.
As mentioned above, the uniqueness of a large bullish K-line is not reflected in the PSY indicator, it's merely treated as an upward line with no difference from the previous small bearish K-line. This is where the problem lies, as the number of rises and falls cannot fully describe the magnitude and direction of price changes. Therefore, our first improvement idea was to weight each BAR's price change Abs(C-C[1]) to reflect the magnitude of rise and fall forces. The source code for initial PSY+PRICE factor function based on FMZ platform:
> PART3 Final PSY Factor (PSY+PRICE+VOL)
After the modification in the previous step, the transformed PSY factor can better reflect the strength and weakness over a period of time. However, it cannot distinguish well if the rise and fall range is basically consistent during that period. At this point, we continue to add trading volume factors. In momentum effect, increased volume represents a more active market, and increased volume situation can better confirm momentum direction. As shown in the figure below:
Over the past period of time, the magnitude of the rise and the fall were basically the same, but the volume in the rise far exceeded the volume in the fall, reflecting the superior upward force. Therefore, in the final PSY factor, we continue to add the volume factor weighting, VOLUME*Abs(C-C[1]), based on the initial PSY+PRICE factor function source code of FMZ platform:
> PART4 Construction of PSY Factor Trading Signals
Based on the final PSY+PRICE+VOL factor constructed in the previous article, we attempt to propose several constructions of momentum signals as follows:
- psy[0] > X (Over a period of time in the past, the ratio of multiple forces was greater than X value.)
- psy[0] < Y (Over a period of time in the past, the ratio of multiple forces was less than Y value.)
- psy[0] > psy[1] or psy[0] > psyma (Over the past period of time, the ratio of various forces has increased.)
- psy[0] < psy[1] or psy[0] < psyma (Over a period of time, the ratio of multiple forces has decreased.)
We design a simple momentum strategy with signals to detect factors.
- Go long: PSY[0] > 70; Close long position: PSY[0] < 30;
- Go short: PSY[0] < 30; Close short position: PSY[0] > 70;
Using Binance U-denominated contracts, the PSY factor parameter is designed to be 12. Backtesting of BTC-USDT and ETH-USDT contracts was conducted from February 1, 2020 to December 31, 2021 with a slippage of 10, a transaction fee of 0.05%, a leverage of 10 times, and each position remaining principal at 5%:
BTC-USDT：
ETH-USDT：
> PART5 Summary
In this article, we upgraded and transformed the traditional psy factor, resulting in a psy+price+vol factor that can measure the strength of bulls and bears over a past period at the level of volume and price. Using fixed numerical comparisons or self-strength comparisons, corresponding momentum/reversal signals can be constructed. This article finally established a fixed numerical signal, conducted simple strategy backtesting, and found that the psy+price+vol factor can capture momentum movements in volatile markets to some extent, achieving positive expected returns. More forms of signals can be constructed later for more types of factor tests before ultimately being added to an existing strategy library.

1,866,058 | The Essential Zsh Config for Beginners | Introduction The shell is an important tool to learning how to configure your computer... | 0 | 2024-05-27T03:07:43 | https://dev.to/hackman78/the-essential-zsh-config-for-beginners-o40 | ## Introduction
The shell is an important tool to learning how to configure your computer because it is what controls how you interact with your computer at a fundemental level.
The shell is what you interact with every time you enter a terminal session so it is important to have a base level understanding so that you can become more productive.
I think that learning some basic commands, customizing your shell for what you need and not being afraid to break your system all are apart of sorftware engineering.
I personally have messed some things up on my computer, but gaining problem-solving skills and going through a bootcamp has given me the tools and confidence to know that I can fix any of the problems at hand. So i wanted to give a simple configuration to jumstart you to a beetter quality of life config that should work for everybody.
There are three simple plugins I recommend plus giving youself a theme to look at and some simple aliases to add to your configuration and thats all you need with no panic
## Basic Setup
To start off I personally work with node alot and need this line so I just added it to the top of the file
```
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
```
This is to load NVM to your terminal everytime your terminal starts up. If you ever have a message that nvm doesn't exist when you run the command this with make it availble to you
### Homebrew
Next this is for Macos users to load homebrew into their terminal you can use this code snippet
```
if [[ -f "/opt/homebrew/bin/brew" ]] then
# If you're using macOS, you'll want this enabled
eval "$(/opt/homebrew/bin/brew shellenv)"
fi
```
HomeBrew is a package manager to install any programs write from your terminal it is really useful and is essential for any developers.
### Zsh Package Manager
Next we need to load a zsh package manager so that we can load the essential things needed so that we can customize our terminal. There are many package managers you can use and their is a big debate about all of them, I personally use Zinit, but their are plenty you can use like oh-my-zsh, zplug, etc.
All of these are just fine to use with different problems with each, I use zinit because it is very lightweight and allows my terminal to startup fairly quickly.
To startup with zinit you will need to add these lines
```
# Set the directory we want to store zinit and plugins
ZINIT_HOME="${XDG_DATA_HOME:-${HOME}/.local/share}/zinit/zinit.git"
# Source/Load zinit
source "${ZINIT_HOME}/zinit.zsh"
# Download Zinit, if it's not there yet
if [ ! -d "$ZINIT_HOME" ]; then
mkdir -p "$(dirname $ZINIT_HOME)"
git clone https://github.com/zdharma-continuum/zinit.git "$ZINIT_HOME"
fi
```
## Core Plugins
Next I setup some of the core plugins that i think have really helped me the most.
Those would be zsh-syntax-highling, zsh-completions, and zsh-autosuggestions. These three allow me to really know what I'm doing in my terminal and allows me to see old commands that i have run and just re-execute better that using my up arrow in the terminal.
### Zsh-Syntax-Highlighting
It is really a cool plugin it highlights commands when they are actuall commands underlines files when they exist in your current directory and just lets you know when you are actually doing the right thing. This kind of thing is important for a beginner because when you are only looking at a default terminal it is really hard to know what/if you are doing the right thing.
### Zsh-Completions
This plugin is really nice because it allows the terminal to complete command for you so that you don't have to type your whole command out. This plugin ties in really well with zsh-autosuggestions to really allow you to see all that you are doing in the terminal.
### Zsh-autosuggestions
It will read your terminal history and suggest commands to you based on your zsh history and allow you to complete `npm start`, `npm run build`, `npm test`. These may seem simple but when your lazy like me its a big deal.
```
zinit light zsh-users/zsh-syntax-highlighting
zinit light zsh-users/zsh-completions
zinit light zsh-users/zsh-syntax-highlighting
# Add in snippets
zinit snippet OMZP::git
# Load completions
autoload -Uz compinit && compinit
```
## Themes
I personally suggest using powerlevel 10k as it has alot of options but their are many terminals online and it is very hard to cover all of the options out their so i will show how to install powerlevel 10k but it is really up to you on what you like. To install use
```
# Add in Powerlevel10k
zinit ice depth=1; zinit light romkatv/powerlevel10k
```
and when you get into the terminal and type `p10k configure` into your terminal and execute and it will show prompts to guide you to configure your promt how you like it. You may also have to install a nerd font to get this working properly.
## Aliases
These steps are optional but i suggest them for a better expierence. I suggest adding these because the allow you to shorten your syntax when doing anything in your terminal. I like shortening things if you haven't noticed
I also suggest if you use ls to install eza as it gives you a nicer looking ls command with highlighting so you can see clearly which are files vs directories and so on.
to install eza it is `brew install eza`
```
## Everyday Aliases
alias ls="eza --icons=always"
alias cl='clear'
## Git Aliases
alias gad='git add'
alias gst='git status'
alias gl='git pull'
alias gp='git push'
alias gc='git commit -v'
## Very Nice looking git log graph, imo
alias glol="git log --graph --pretty='%Cred%h%Creset -%C(auto)%d%Creset %s %Cgreen(%ar) %C(bold blue)<%an>%Creset'"
## Zsh Config Aliases [If you ever want to reconfigure this file use these]
alias zconfig="c ~/.config/zsh/.zshrc"
alias rezsh="source $ZSH_HOME"
```
Don't be intimidated by these steps. Diving into new thing that may seem daunting at first is part of programming but seeing others do it, and realizing the benefits will make it worth it. I know most of you will be like no that's too much I don't want that. It's fine everybody is on their own journey but i promise it is well worth it when you make the jump.

Chaos engineering, using tools like LitmusChaos, intentionally introduces faults to uncover systemic issues missed by traditional tests. From now on, we can use k6, a load-testing tool with LitmusChaos. This post explores chaos engineering with LitmusChaos and demonstrates a k6 load chaos experiment.

### What are chaos engineering and LitmusChaos
What if our systems suddenly experience an outage? It's difficult to pinpoint the problem these days, especially since our systems are on Kubernetes, meaning they are microservices. While unit tests and integration tests can detect our application's weaknesses, they cannot detect weaknesses in our overall platform.
[The above diagram](https://docs.litmuschaos.io/docs/introduction/what-is-litmus#importance-of-resilience) shows the impact of resilience. Using chaos engineering can be a great way to achieve more than 90% resilience. Chaos Engineering is the discipline of experimenting on a system in order to build confidence in the system’s capability to withstand turbulent conditions in production [1]. Chaos engineering involves intentionally injecting faults into a system to test its resilience. LitmusChaos makes this process easier to implement by simplifying Chaos Engineering.
[LitmusChaos](https://litmuschaos.io/) (CNCF incubating project) is a Cloud-Native Chaos Engineering Framework with cross-cloud support. You can use Litmus to inject controlled chaos and run chaos experiments in staging and production environments, allowing SREs to identify bugs and vulnerabilities. If you want to know more about Litmuschaos, Check out the [documentation](https://docs.litmuschaos.io/)!
### Introduction to k6
k6 is an open source load testing tool designed for developers to allow teams to create tests-as-code, integrate performance tests as part of the software development lifecycle, and help users test, analyze, and fix application performance issues. k6 supports [various types](https://grafana.com/docs/k6/latest/testing-guides/test-types/) of load testing (ex. spike, smoke, stress).
Now LitmusChaos supports k6 load testing as a chaos fault so that we can simulate load generation to the target application as a part of chaos testing on Kubernetes.
To know more about it, check out this [documentation](https://litmuschaos.github.io/litmus/experiments/categories/load/k6-loadgen/). You can also find our integration in the [k6 documentation](https://grafana.com/docs/k6/latest/misc/integrations/#chaos-engineering) 🚀
### Injecting k6 load chaos with LitmusChaos (demo)
Let us run the k6-loadgen chaos experiment. For simplicity, we will be injecting chaos into an [OpenTelemetry Demo](https://opentelemetry.io/docs/demo/).
#### Prerequisites
- [Docker](https://docs.docker.com/engine/install/), [minikube](https://minikube.sigs.k8s.io/docs/start/) (If you use your k8s cluster, skip this)
- Check out the otel-demo's [Prerequisites](https://opentelemetry.io/docs/demo/kubernetes-deployment/#prerequisites)
- If you haven't installed LitmusChaos yet, check out this [documentation](https://docs.litmuschaos.io/docs/getting-started/installation).
#### Install opentelemetry demo
After installing Minikube and LitmusChaos, We now install the opentelemetry demo. All you have to do is enter the code below.
```bash
helm repo add open-telemetry https://open-telemetry.github.io/opentelemetry-helm-charts
helm install my-otel-demo open-telemetry/opentelemetry-demo
```
If you want to customized a deployment setting, check out this [documentation](https://opentelemetry.io/docs/demo/kubernetes-deployment/).
We cannot directly access the otel-demo service, so we are using minikube's command to get an external URL
```bash
minikube service my-otel-demo-frontendproxy --url
```
the result is like one below
We now access the frontend service
You can access Grafana using given URL
```bash
http://<<given_url>>/grafana
```
We will use `Home > Dashboards > Demo Dashboard` today.
#### Setup Probes
You can easily create a probe following this [documentation](https://docs.litmuschaos.io/docs/user-guides/create-resilience-probe). Enter a value like below.
```bash
// URL: http://my-otel-demo-frontendproxy.default.svc.cluster.local:8080
// METHOD: GET
// CRITERIA: ==
// Response Code: 200
```
#### Writing a k6 script
You don't have to install a k6 engine! We just have to write a k6 script. We will use the below code and save it as `script.js`
```js
import http from 'k6/http';
import { sleep } from 'k6';
export const options = {
vus: 1000,
duration: '30s',
};
export default function () {
http.get('http://my-otel-demo-frontendproxy.default.svc.cluster.local:8080');
sleep(1);
}
```
If you'd like to write a more professional script, you can check out this [documentation](https://grafana.com/docs/k6/latest/).
and let's make a secret
```bash
kubectl create secret generic k6-script \
--from-file=<<script-path>>/script.js -n <<chaos_infrastructure_namespace>>
```
Now that all the preliminary work is done, let's create a chaos experiment.
#### Let's make a chaos experiment
Click `Chaos Experiments` > `+ New Experiment` to create a new chaos experiment.
After clicking the `Blank Canvas` and `Add` buttons, we can choose chaos fault in ChaosHub. We use `k6-loadgen`
We don't have to enter any values into the `Target Application` (we will fix it later). In the `Tune Fault` tab, we enter the secret name and key we created before.
Lastly, We add a probe that was created before.
Okay, all done! Let's execute a chaos experiment 🚀
A few minutes later, Our chaos experiment succeeded. Congratulations 🎉

## What I Built
The project presents a robust, scalable, and efficient video transcoding service designed to
cater to the needs of high-demand video processing. The service leverages modern web
technologies and cloud infrastructure to offer seamless video transcoding capabilities that
support various media formats. This service is especially designed to be a cost-effective
and efficient solution for content creators, media professionals, and businesses looking to
enhance their digital media workflow.
## Demo and Code

####
**CODE:** [https://github.com/jatingodnani/trancoding-service](https://github.com/jatingodnani/trancoding-service)
## Integrations
- **Frontend Interface:** Developed using Next.js, the frontend is designed as a responsive web application that provides users with a seamless interface to upload, manage, and view transcoded videos. The choice of Next.js facilitates server-side rendering and static site generation, which enhances the performance and SEO of the platform.
- **Message Queue and Counters:** Redis is employed as a message broker and for managing counters. It handles job queueing processes, ensuring that video transcoding tasks are executed in an orderly and efficient manner. Redis's high- speed data handling capabilities make it ideal for tasks that require real-time data
processing.
- **Containerization with AWS ECS:** Each video transcoding process is isolated within a container, managed via Amazon Elastic Container Service (ECS). This allows for scalable and efficient management of computational resources. Containerization ensures that each transcoding task is securely and independently handled, improving the reliability of the service. Tasks are serverless (on Fargate) which further enhances scalabality.
- **Storage and Database Management:** Amazon DynamoDB is used to store
metadata and links to the transcoded videos stored in Amazon S3 buckets.
DynamoDB offers fast and flexible NoSQL database solutions that scale seamlessly alongside the growth of the service. This integration ensures durable and cost-
efficient storage of large volumes of data.
- **Docker and Amazon ECR:** The service uses Docker for creating and managing the application's container images, ensuring consistent environments across development, testing, and production. Amazon Elastic Container Registry (ECR) is used for storing and managing Docker container images, facilitating smooth deployment processes and secure storage of application images.
<!-- Reminder: Qualifying technologies are data, authentication, serverless functions, and file storage as outlined in the guidelines -->
**Connected Components and/or Feature Full**
- **Scalable Video Transcoding:** Capable of handling multiple video transcoding tasks
concurrently without compromising on processing time or quality.
- **User-Friendly Dashboard:** Enables users to easily upload videos, monitor the status
of transcoding processes, and access the output from a single, intuitive interface.
- **Support for Multiple Formats:** Offers support for a wide range of video formats,
providing flexibility for users to upload various types of media files.
- **Cost-Effective:** Optimized resource usage and cloud integration reduce operational
costs, making it an affordable solution for all scales of users.

# Introduction to Scheduler
`Scheduler` is a package in React responsible for task scheduling, and it lays the groundwork for implementing time slicing. The upcoming `useEffect` will also utilize it, so in this article, we'll start by implementing a WASM (WebAssembly) version of the `Scheduler`.
For an introduction to `Scheduler`, you can refer to [this article](https://www.paradeto.com/2020/12/30/react-concurrent-1/) I wrote previously. Below is a brief introduction to its implementation.
`Scheduler` maintains two min-heaps: `timerQueue` and `taskQueue`. Tasks that are ready (`startTime` <= `currentTime`) are placed into the `taskQueue`, while tasks that are not yet ready (with `startTime` > `currentTime` achieved by passing in a `delay`) are placed into the `timerQueue`. For instance, in the example below, `task1` would be placed into the `taskQueue`, while `task2` would be placed into the `timerQueue`.
```js
const task1 = Scheduler.unstable_scheduleCallback(2, function func1() {
console.log('2')
})
const task2 = Scheduler.unstable_scheduleCallback(
1,
function func2() {
console.log('1')
},
{delay: 100}
)
```
Later on, a macro task is initiated through `MessageChannel` to process the tasks in the `taskQueue`. If the processing time exceeds 5ms, it will be interrupted, and then a new macro task will be started to continue processing the remaining tasks. This cycle repeats until all tasks in the heap are completed. Tasks in the `timerQueue` are periodically checked to see if they are ready. If they are, they are popped out in sequence and placed into the `taskQueue`.
The details of this update can be seen [here](https://github.com/ParadeTo/big-react-wasm/pull/13/files). Below, I will highlight and explain some key points.
# Implementation of Min Heap
To facilitate writing unit tests, a generic version of the min heap was implemented:
```rust
...
pub fn push<T: Ord>(heap: &mut Vec<T>, value: T) {
heap.push(value);
sift_up(heap, heap.len() - 1);
}
...
fn sift_up<T: Ord>(heap: &mut Vec<T>, mut index: usize) {
while index != 0 {
let parent = (index - 1) / 2;
if heap[parent] <= heap[index] {
break;
}
heap.swap(parent, index);
index = parent;
}
}
...
```
However, this generic `T` is constrained by `Ord`, requiring the implementation of the `Ord` trait, like this:
```rust
struct Task {
id: u32
}
impl Eq for Task {}
impl PartialEq for Task {
fn eq(&self, other: &Self) -> bool {
self.id.cmp(&other.id) == Ordering::Equal
}
}
impl PartialOrd for Task {
fn partial_cmp(&self, other: &Self) -> Option<Ordering> {
return self.id.partial_cmp(&other.id);
}
}
impl Ord for Task {
fn cmp(&self, other: &Self) -> Ordering {
self.partial_cmp(other).unwrap_or(Ordering::Equal)
}
}
```
# static mut
The implementation of `Scheduler` defines a large number of `static mut`, leading to many unsafe code blocks in the code. Clearly, this is not a good practice, but the advantage of doing so is that the implementation is more similar to React's, which facilitates copying code. Moreover, another more important reason is that if we do not use `static mut`, but instead define a `Scheduler` struct and make these `static mut` as its attributes, other problems will be encountered.
For instance, when using `perform_work_until_deadline` as the callback function for a macro task, it would need to be changed to `self.perform_work_until_deadline`, and such a change would not compile:
```rust
pub fn schedule_perform_work_until_deadline() {
let perform_work_closure =
// Will fail to compile if it is changed to self.perform_work_until_deadline
Closure::wrap(Box::new(perform_work_until_deadline) as Box<dyn FnMut()>);
```
Even changing it to a closure would not work:
```rust
pub fn schedule_perform_work_until_deadline() {
let perform_work_closure =
Closure::wrap(Box::new(|| self.perform_work_until_deadline()) as Box<dyn FnMut()>);
```
Therefore, it seems to be a necessary evil for the time being. However, by using unsafe to bypass Rust's safety checks, some strange behaviors can occur, such as the following example:
```rust
static mut MY_V: Vec<Task> = vec![];
#[derive(Debug)]
struct Task {
name: String
}
fn peek<'a>(v: &'a mut Vec<Task>) -> &'a Task {
&v[0]
}
fn pop<'a>(v: &'a mut Vec<Task>) -> Task {
let t = v.swap_remove(0);
t
}
fn main() {
unsafe {
MY_V = vec![Task {
name: "ayou".to_string()
}];
let t = peek(&mut MY_V);
// 1
// pop(&mut MY_V);
// 2
let a = pop(&mut MY_V);
println!("{:?}", t.name);
};
}
```
Code 1 and Code 2 produce different outputs. Code 1 outputs `"\0\0\0\0"`, while Code 2 outputs normally, and the only difference between them is whether the return value is assigned to a variable or not.
As to why there is such a difference, it's not yet very clear. Fortunately, testing has revealed that there are no other issues for now, and next, we can proceed to implement `useEffect`.
Please kindly give me a star!

1,866,054 | Fix "The permission 'KILL DATABASE CONNECTION' is not supported in this version of SQL Server" while importing a D365FO .bacpac | Recently, while making a copy of production database to my development environment, I came across an... | 0 | 2024-05-27T02:58:30 | https://dev.to/edoardu/fix-the-permission-kill-database-connection-is-not-supported-in-this-version-of-sql-server-while-importing-a-d365fo-bacpac-4k81 | sql, d365fo, sqlpackage, erp | Recently, while making a copy of production database to my development environment, I came across an unusual error when importing the .bacpac file using [SqlPackage](https://learn.microsoft.com/en-us/sql/tools/sqlpackage/sqlpackage-download?view=sql-server-ver16):
```
*** Error importing database: Could not import package.
Error SQL72014: Core Microsoft SqlClient Data Provider: Msg 4630, Level 16, State 1, Line 1 The permission 'KILL DATABASE CONNECTION' is not supported in this version of SQL Server. Alternatively, use the server level 'ALTER ANY CONNECTION' permission.
Error SQL72045: Script execution error.
The executed script: GRANT KILL DATABASE CONNECTION TO [ms_db_configreader];
```
After some digging, I was abble to resolve the problem following the solution below.
## Solution
This solution will help you to edit **model.xml** file contained inside the package and remove/replace the KILL ANY CONNECTION statement.
- Make a backup of your original .bacpac package.
- Go to your package in File Explorer and change his file extension from .bacpac to .zip. The renamed file should look like this:
- Now you can open the renamed package and extract the model.xml file into another folder:
- Open the **model.xml** file with Notepad or another text editor and search for "**Grant.KillDatabaseConnection.Database**".
- The search should return one or more **SqlPermissionStatement** elements. You can remove¹ these elements from the **model.xml** file.
- After this, save and close the modified **model.xml** file.
- Then copy and replace the modified **model.xml** into the zipped package and change the package file extension from .zip to .bacpac again. Your files should look like this:
Here comes the fun part, usually you would have to extract the package completely, modify the model.xml file, generate a new checksum, update the **Origin.xml** file with the new checksum value and then compress the package again.
Instead, you can skip all this work by using the [SqlPackage import](https://learn.microsoft.com/en-us/sql/tools/sqlpackage/sqlpackage-import?view=sql-server-ver16) parameter **/ModelFilePath** (/mfp):
```
.\sqlpackage.exe /a:import /sf:"C:\Users\localadmin\Desktop\Goldenbackup.bacpac" /mfp:"C:\Users\localadmin\Desktop\model.xml" /tsn:localhost /tdn:AxDB_fromGolden /ttsc:true /p:CommandTimeout=0
```
Parameters description:
- **/sf**: put your .bacpac package file path here.
- **/mfp**: overrides the model.xml in the source file with the modified model.xml.
Now the .bacpac package will be imported successfully. 😊
## Final considerations
¹ Instead of removing the **SqlPermissionStatement** elements, you can also replace the permission "**Grant.KillDatabaseConnection.Database**" with "**Grant.AlterAnyConnection.Database**".
² This solution also solves the error "**Operation Failed: File contains corrupted data**" while importing a .bacpac package in SSMS. | edoardu |
1,846,132 | How to Deploy a Django Full-stack Application over Kubernetes | TL;DR: In this tutorial, we will learn to deploy a sample Django Full Stack Application on Kubernetes... | 0 | 2024-05-27T02:41:18 | https://devtron.ai/blog/how-to-deploy-a-django-full-stack-application-with-kubernetes/ | django, kubernetes, devtro, cicd | TL;DR: In this tutorial, we will learn to deploy a sample Django Full Stack Application on Kubernetes using Devtron and implementing GitOps.
Welcome to another blog from the Devtron ecosystem! In this tutorial, you'll learn to deploy a Django Full-stack Application over Kubernetes using Devtron. The best part is you don't need to worry about manually working with K8s configuration files or setting up a CI/CD pipeline. The Devtron platform would seamlessly do everything with a few button clicks.
Let's see how it is done!
## Pre-requisites
Before moving forward, let's look at all the things you'll require to follow along:
1. A full-stack Django Application on GitHub
For this tutorial, we'll be using a simple To-Do List application with PostgreSQL as the database. The application can be accessed from the repo.
2. Devtron installed and configured on your machine
If you haven't installed Devtron, feel free to check out the well-managed documentation and join the Discord community for help!
## Setting up the database - PostgreSQL
Our application uses PostgreSQL as the database, so the very first step would be to deploy that. Here, we'll be using a community Helm Chart and deploying it with the help of the Helm dashboard by Devtron.
## Step 1: Visit Chart Store
Navigate to the Chart Store on the Devtron Dashboard and search for postgresql. For this tutorial, we'll be using the bitnami/postgresql(12.1.6) chart, as shown below:
## Step 2: Chart Selection
Click on the preferred chart where you may refer to the README to learn more about the helm chart.
Head over to Configure & Deploy, where you'll be further setting up your chart configurations.
## Step 3: Chart Configuration
In the configuration window, the following details must be provided:
- App Name
- Project
- Environment
You can directly make changes in the chart's configuration file `(values.yaml)` here as per your requirements. For this tutorial, please add the following details:
```
auth:
postgresPassword: "<root_password>"
username: "<new_user>"
password: "<user_password>"
database: "<database_name>"`
Once these parameters are properly set, you are ready to deploy your chart.
Click `Deploy Chart
```
Congratulations! Your PostgreSQL database is up and running! You can now view the chart details by heading to Helm Apps/PostgreSQL on the dashboard.
You will be able to check out all the resources it has deployed, including
- status of the application,
- chart version, and many more, as shown below.
> NOTE: Please note the service name from here, as that will be used while configuring the Django application.
> In this case, it's `postgresql-2-devrel`
## Configuring the Application - Database Settings
Before we dive into deploying our app using Devtron, we have to make some changes to the database settings. Head over to settings.py of our Django application, which contains the configuration for your SQL database.
Make sure the configurations in settings.py match the ones of the PostgreSQL Helm Chart we deployed in the steps above.
In this case, we are providing all the root user's details.
```
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': '<database_name>',
'USER': '<root_username>',
'PASSWORD': '<root_password>',
'HOST': '<service_name>',
}
}
```
Once we have configured these settings, we are ready to deploy the application using Devtron
## Deploying the Application
It's interesting to know that Devtron is capable of deploying any kind of application irrespective of the language or tech-stack chosen for the project.
Before we create an application, ensure your Global Configurations are set and properly validated.
Please refer to the documentation for more information on the different sections of Global Configurations available in Devtron.
## Step 1: Create a Custom Application
Head over to the `Create` drop-down on the Devtron dashboard and select `Custom App`. Provide the necessary details asked in the prompt window and click `Create App`
## Step 2: App Configurations
After creating an app, you will be redirected to the App Configuration tab, where you need to provide the following details:
1. Git Repository: The link to your project on GitHub
- In this case, we are using a simple To-Do app
2. Build Configuration: Provide all the docker-related information to build and push docker images of your app
- Provide the details for the container repository to store your image
- We are using a Dockerfile for our application, so we will give the path to the same
- You can also choose buildpacks as an option to deploy your application if you don't have a Dockerfile. For more information, please refer to the documentation
3. Base Deployment Template: The main deployment configuration goes here. The beauty of using the Deployment template is that you don't need to manually configure things like pod specs, hpa, service, ingress, etc. All these come pre-configured with the template, and you just have to tweak some values as per the requirements.
Following are the steps to configure the deployment of our app:
Step 1: Select a chart type from the following options:
- Deployment (Recommended)
- Rollout Deployment
- Job & CronJob
## Step 3: Configure Ingress
Configuring the ingress controller parameters as follows:
```
ingress:
annotations: {}
className: "nginx"
enabled: true
hosts:
- host: <YOUR_DOMAIN>
pathType: ImplementationSpecific
paths:
- /<END_POINTS>
```
- You can also refer to the README for the specific Deployment Chart, provided on the platform itself to configure more parameters as per your requirements.
- Feel free to check out this blog to configure the ingress controller using Devtron.
1. Workflow Editor: Here, you can set up a simple CI/CD pipeline for the application in no time using the platform itself. There are mainly 3 types of pipelines that can be created here: (More information in the documentation)
- Continuous Integration
- Linked CI Pipeline
- Incoming Webhook
Furthermore, the CI pipeline may also include Pre and Post-build stages to validate and introduce checkpoints in the build process. These can either be configured using some preset plugins like k6, Sonarqube, etc. (as shown below) or using custom scripts as well.
For more information on Pre-build/Post-build tasks, please refer to the documentation.
## Creating a CI/CD pipeline for our Django Application
## Step 1: Create CI Pipeline
For creating a CI pipeline, click on `+ New Workflow -> Build & deploy` the source code. In the `Create Pipeline` window, provide the necessary details as shown below and click on Create Pipeline:
## Step 2: Create CD Pipeline
To create the deployment pipeline, click the `+` icon corresponding to the CI. Configure the details as required, and click on Create Pipeline.
Awesome! You now have a fully configured CI/CD pipeline for your application.
To know more about using the Workflow Editor, refer to the documentation.
As we don't have any `ConfigMaps` or `Secrets` for this application, let's move to the Build & Deploy tab and trigger the CI Build.
Step 3: Build and Deploy
In the `Build & Deploy` tab, click Select Material then select the commit against which you want to build an image, then click Start Build.
This will start building your image. You can also view runtime logs, commit details for the particular build, security results (if enabled), and artifacts.
Once the build is successful, the status will be updated accordingly!
## Step 4: Deploy using the Image
Now is the time to deploy the application using the image we built in the previous step.
Now, we can check the status of our deployment on the App Details tab. Once the deployment is successful, it will reflect the `Application Status: Healthy`.
Furthermore, you can view all additional information about your deployed application such as:
- The deployment environment
- K8s resources like pods, services, etc
- Manifests of individual resources
- logs, and much more
Step 5: View your Deployment
We have successfully deployed our Django app over Kubernetes 🎉
To check whether our application and database are running successfully, we can view this in our browser.
The syntax is: `http://<hostname>/<path>`
`hostname` & `path` would be the ones given in ingress while configuring the Deployment Template (refer to the steps above)
> NOTE: An additional step here could be mapping your domain_name with the load balancer IP address, which can be found in the manifest of ingress (as shown below)
```
status:
loadBalancer:
ingress:
- ip: <IP_ADDRESS>
```
## Conclusion
We have successfully deployed our Django Application over Kubernetes using Devtron. If you like Devtron, do give us a ⭐️ on GitHub, and feel free to join the Discord community for all the latest updates.

1,866,051 | Bread in a Jar | Bread in a Jar: Understanding the Concept In the world of technology and programming,... | 0 | 2024-05-27T02:40:17 | https://dev.to/firebaseme/bread-in-a-jar-3nah | programming, beginners, debugging, learning | # Bread in a Jar: Understanding the Concept
In the world of technology and programming, there's a humorous and enlightening concept known as "duck programming." This idea involves explaining your code or problem to a rubber duck, and in doing so, often revealing the solution to yourself. Similarly, there's a new concept called "bread in a jar" that addresses a common issue faced by many tech enthusiasts and developers. This concept illustrates the scenario where one understands individual components (A and B) or knows how to execute specific tasks but struggles with their correct implementation or integration, often reversing the intended order or logic.
## The Concept Explained
Imagine you have a jar labeled "peanut butter," but instead of containing peanut butter, it's filled with slices of bread. Each slice of bread represents a piece of knowledge or a skill you possess. Instead of spreading peanut butter on bread to make a sandwich, you've put bread inside the peanut butter jar. While the components are related, their implementation is incorrect, leading to confusion and inefficiency.
This analogy reflects the experience of many developers: you know how to write functions, understand databases, or use APIs, but integrating these components into a cohesive and functional system can be challenging. This mismatch often results from a lack of understanding of the overall system architecture or the interdependencies between different parts.
## Examples in Programming
Let's explore some examples in programming, particularly using Firebase services, to illustrate this concept further.
### 1. Firebase Authentication and Firestore
- **Understanding A and B**: You know how to implement Firebase Authentication to allow users to sign in and how to set up Firestore to store user data.
- **The Breakdown**: You might try to store user data in Firestore before the user is authenticated, leading to issues where data is not properly linked to the user.
**Solution**: Ensure that the user is authenticated first, then use the unique user ID (UID) provided by Firebase Authentication as a key in Firestore to store and retrieve user-specific data. This ensures that each user's data is securely linked to their account.
```javascript
firebase.auth().onAuthStateChanged((user) => {
if (user) {
const uid = user.uid;
const userDocRef = firebase.firestore().collection('users').doc(uid);
userDocRef.set({
name: user.displayName,
email: user.email,
// additional user data
});
}
});
```
### 2. Firebase Cloud Functions and Firestore
- **Understanding A and B**: You can write Firebase Cloud Functions to perform backend logic and know how to read/write data in Firestore.
- **The Breakdown**: You might write Cloud Functions that attempt to modify Firestore data directly without considering the event-driven nature of Cloud Functions.
**Solution**: Use Firestore triggers in your Cloud Functions to listen for specific events (e.g., document creation, update, deletion) and execute the corresponding logic. This approach ensures that your backend logic runs automatically in response to changes in your database.
```javascript
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
exports.onUserCreate = functions.firestore
.document('users/{userId}')
.onCreate((snap, context) => {
const newValue = snap.data();
// Perform actions based on the new user data
console.log('New user created:', newValue);
});
```
### 3. Firebase Hosting and Firestore Security Rules
- **Understanding A and B**: You know how to deploy a web app using Firebase Hosting and set up Firestore Security Rules to protect your data.
- **The Breakdown**: You might configure Security Rules that are too restrictive or too lenient, either blocking legitimate access or allowing unauthorized access.
**Solution**: Learn how to use Firestore Security Rules to define fine-grained access controls based on user authentication status and custom claims. By combining Hosting and Security Rules, you can ensure that your web app serves content securely and only to authorized users.
```javascript
service cloud.firestore {
match /databases/{database}/documents {
match /users/{userId} {
allow read, write: if request.auth != null && request.auth.uid == userId;
}
}
}
```
## Example Conversation: Bread in a Jar Problem
**Dev 1**: "Firebase is not working. Help!"
**Dev 2**: "Alright, did you add your Firebase credentials in the HTML?"
**Dev 1**: "Yep, they’re there."
**Dev 2**: "Did you import and initialize Firebase in your JS?"
**Dev 1**: "Is that important?"
```javascript
// Firebase config
var firebaseConfig = {
apiKey: "your-api-key",
authDomain: "your-auth-domain",
projectId: "your-project-id",
storageBucket: "your-storage-bucket",
messagingSenderId: "your-messaging-sender-id",
appId: "your-app-id"
};
// Initialize Firebase
firebase.initializeApp(firebaseConfig);
```
**Dev 1**: "Got it. I missed that part."
**Dev 2**: "Classic bread-in-a-jar move. Did you set up Firestore too?"
**Dev 1**: "Nope. What’s that?"
**Dev 2**: "It's your database. Add this after initializing Firebase:"
```javascript
var db = firebase.firestore();
```
**Dev 1**: "Okay, added. Anything else?"
**Dev 2**: "Check your Firestore security rules. Sometimes they’re too tight. Here’s a basic one:"
```javascript
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if request.auth != null;
}
}
}
```
**Dev 1**: "Thanks! I was totally putting bread in the peanut butter jar."
**Dev 2**: "No worries. Now spread that peanut butter properly. Let me know if you get stuck again!"

1,866,042 | Introducing Live Feedback | Update: https://dev.to/juliankominovic/update-live-feedback-script-35oi Take a look at the demo... | 0 | 2024-05-27T02:34:26 | https://dev.to/juliankominovic/introducing-live-feedback-2cg8 | webdev, javascript, react, productivity | Update: https://dev.to/juliankominovic/update-live-feedback-script-35oi
Take a look at the demo video [here](https://github.com/JulianKominovic/live-feedback?tab=readme-ov-file#demo).
{% embed https://github.com/JulianKominovic/live-feedback %}
Today I'm going to introduce a new Google Extension that I've been working on the past few weeks.
`Live feedback` is an extension made for Google Chrome browser that allows you to get feedback on your website in real time from your developers, designers, and clients. It is a simple and easy-to-use tool that helps you to improve your website by getting feedback right on the page.
The extension is designed to be simple and intuitive, so you can start using it right away without any training by following [these simple steps](https://github.com/JulianKominovic/live-feedback?tab=readme-ov-file#instructions).
It's very similar to [Vercel Comments](https://vercel.com/docs/workflow-collaboration/comments), but it's open source and it's not tied to any specific platform, so you can use it everywhere, even on your local development environment.
> Disclaimer: The extension is under development and it's not ready for production yet. I'm still working on it and adding new features so you may encounter some bugs or issues while using it. Some major changes may happen in the future as well. If you have any feedback or suggestions, please let me know in the comments.
## What does it do?
The extension allows you to select an element on the page and add a comment to it.
When you submit the feedback, a screenshot is taken automatically, and the feedback is sent to whatever Github repository you have configured in the extension settings as an issue. You can then view the feedback on Github and discuss it with your team and you also can see the feedback directly on the page as a bubble.
Anyone with access to the repository will see the feedback bubble and will be able to comment on it. This makes it easy to collaborate with your team and improve your website. Just make sure you both have the extension installed and configured with the same repository (since the extension uses Github Issues as a backend).
In case you are reviewing a pull request, you can also link the issue to the pull request, so you can use this tool to review pull requests as well.
## How does it work?
1. The extension injects a small script into the page you are viewing.
2. A toolbar is displayed at the bottom of the page.
3. Click on the toolbar `+` button to start adding feedback.
4. Select an element on the page.
5. Leave a comment.
6. Submit the feedback.
7. 2 screenshots are taken: one of the whole page and one of the selected element. They will be uploaded to your Github repository master branch inside `.github/feedback` folder.
8. A new issue is created in your Github repository with the feedback and the screenshots attached.
9. In the issue, you can see the feedback, the screenshots, and the comments. You can discuss the feedback with your team in the issue comments.
**Please DO NOT MODIFY the issue. The issue saves a lot of internal data that the extension uses to display the feedback. If you modify the issue, the extension will not be able to display the feedback correctly.**
## How to install it?
Follow [these simple steps](https://github.com/JulianKominovic/live-feedback?tab=readme-ov-file#install-extension) to install and configure the extension.
## Features
- Smart HTML Element tracking: Your feedback will be linked to the specific element on the page.
- Commenting: You can add comments to the feedback to provide more context.
- Screenshot: Screenshots are taken automatically when you submit feedback.
- No backend required: The extension uses Github Issues as a backend, so you don't need to set up a server.
- Open source: The extension is open source, so you can contribute to its development.
- Trusthworthy: The extension only requires the permissions it needs to work, and it doesn't collect any personal data. Any data collected is stored on your Github repository. You can see every request the extension makes in the network tab of the developer tools.
## Checklist
I'm still working on the extension, and I plan to add more features in the future.
If you have any feedback or suggestions, please let me know in the comments.
You may encounter some bugs or issues while using the extension. If you do, please report them on the [repository](https://github.com/JulianKominovic/live-feedback).
Soon I will be adding a roadmap to the repository so you can see what features are planned and what features are already implemented in detail.
As of now, the extension has the following features:
- [x] HTML Element tracking
- [x] CSS Selector system: list of selectors to find the element and kind of consensus criteria to find the element.
- [x] Typical display attributes: display, visibility, opacity, and pointer-events.
- [x] Feedback coordinates: x and y coordinates of the element and viewport scroll position.
- [] Efficient tracking: stop using polling and use MutationObserver instead. Although it's not a big deal since the extension is not running all the time and didn't have any performance issues.
- [] Lax URL matching: stop making a === comparison and use a more scoped comparison.
- [] Width and height recovery: recover width and height of the viewport of whoever submitted the feedback.
- [] Scroll position recovery: recover scroll position of the viewport of whoever submitted the feedback.

## What is a Palindrome String?
A palindrome is a sequence of characters that reads the same forwards and backwards. For instance, "radar" and "level" are palindromes. They maintain their original form even when reversed. This property makes them intriguing and often used in wordplay and puzzles.
In programming, identifying palindromes is a common task, aiding in string manipulation and pattern matching. Remember, a palindrome retains its symmetry regardless of orientation. So, the next time you encounter a string, consider whether it might be a palindrome!
## What is Palindrome Partitioning?
As discussed above, [a palindrome is a sequence that reads the same forwards and backwards](https://interviewspreparation.com/palindrome-partitioning-a-comprehensive-guide/#what-is-palindrome-string-with-example). Now, let's delve into palindrome partitioning. This process involves splitting a string into substrings, where each substring is a palindrome. For example, given the string "aab", possible palindrome partitions are ["a", "a", "b"] and ["aa", "b"].
## Implementing Palindrome Partitioning in C#
```
using System;
using System.Collections.Generic;
public class Solution {
public IList<IList<string>> Partition(string s) {
var result = new List<IList<string>>();
Backtrack(s, 0, new List<string>(), result);
return result;
}
// to understand below funcation check explanation part named 'How Backtrack Works '
private void Backtrack(string s, int start, List<string> path, List<IList<string>> result)
{
if (start == s.Length) {
result.Add(new List<string>(path));
return;
}
for (int end = start + 1; end <= s.Length; end++) {
if (IsPalindrome(s, start, end - 1)) {
path.Add(s.Substring(start, end - start));
Backtrack(s, end, path, result);
path.RemoveAt(path.Count - 1);
}
}
}
// to understand below funcation check explanation part named 'Find Palindrome String in C#'
private bool IsPalindrome(string s, int left, int right) {
while (left < right) {
if (s[left] != s[right]) {
return false;
}
left++;
right--;
}
return true;
}
}
```
## Find Palindrome String in C#
Consider the string "level." Initially, the 'left' pointer is at the first character ('l'), and the 'right' pointer is at the last character ('l'). We compare both characters and find them to be equal. Next, we increment 'left' and decrement 'right,' so 'left' now points to the second character ('e') and 'right' points to the penultimate character ('e'). This process continues until 'left' is greater than or equal to 'right'. If all comparisons are successful, the function returns true, indicating that "level" is indeed a palindrome.
Follow Interviewspreparation.com to understand [How Backtrack Works](https://interviewspreparation.com/palindrome-partitioning-a-comprehensive-guide/#how-backtrack-works).
## Practical Application
### Case Studies
Imagine you are developing a text editor with a feature to highlight palindromic substrings. By implementing the palindrome partitioning algorithm, you can efficiently identify and highlight these substrings.
### Common Challenges
- Performance: Backtracking can be computationally intensive for large strings.
- Edge Cases: Handling strings with no palindromes.
### Solutions
- Optimisation: Use dynamic programming to store the results of palindrome checks.
- Preprocessing: Validate input to handle edge cases from the outset.
## Summarising the Palindrome Partitioning Guide
In this comprehensive guide, we explored the intriguing concept of palindrome partitioning and its importance, particularly for aspiring programmers preparing for technical interviews. We began by understanding the theory behind palindrome partitioning and delved into its practical implementation using C#. Through a detailed breakdown of the IsPalindrome and Backtrack methods, we decoded the intricate logic behind identifying palindromic substrings and recursively partitioning strings. Despite the initial complexity, we encouraged readers to engage with the code examples, highlighting the importance of practice in mastering algorithms.

**TryOutfit**: Virtual Outfit Try-On with AI
I recently built an AI web application called **TryOutfit** that allows users to virtually try on outfits using AI. Powered by the IDM-VTON model from Replicate, TryOutfit provides an interactive experience for users to visualize how different outfits would look on them or on predefined models.
## How It Works
TryOutfit offers a user-friendly interface where users can either upload their own image or choose from a selection of predefined models. Once an image is selected, the application uses the IDM-VTON AI model to generate a virtual try-on of the chosen outfit on the selected image. This enables users to see how the outfit would look on them or on the model without physically trying it on.
All the model generations are automatically deleted after 1hour from database.
## Demo and Code
APP - https://www.tryoutfit.app/
Code - https://github.com/kaarthik108/tryoutfit
The application follows a serverless architecture, leveraging AWS services to handle various functionalities. User authentication is managed by Amazon Cognito, ensuring secure access to the application. User-uploaded images are stored in S3 buckets, while outfit and user data is stored in DynamoDB tables.
The AI model from Replicate is seamlessly integrated into the application to generate the virtual try-on images. To optimize performance, webhooks are used to poll the inference results instead of waiting for the model to complete the processing. Additionally, TryOutfit offers shareable links to the generated model outfits, which remain accessible for a period of 1 hour, enabling users to easily share their virtual try-on results with others.

## Integrations
- NEXTjs 14 (with server actions)
- AWS s3 (To store image files)
- AWS Dynamo DB (To serve product data and persist inference data)
- AWS Cognito (API Key auth)
- Replicate (AI model)
- AWS Amplify (Hosting)
**Connected Components and/or Feature Full**
StorageImage from Amplify UI was used to display the images using path from s3.
## Conclusion
Building TryOutfit using AWS Amplify and various AWS services has been a rewarding experience. Amplify simplifies the development process by providing a set of tools and services that make it easy to build scalable and feature-rich applications. The integration of AI models, such as the one from Replicate, adds an exciting dimension to the application, enabling users to virtually try on outfits from the comfort of their own devices. | kaarthik108 |
1,866,045 | How do LED display companies respond to the AR/VR market? | The advancement of science and technology has gradually integrated various technologies into people's... | 0 | 2024-05-27T02:19:46 | https://dev.to/sostrondylan/how-do-led-display-companies-respond-to-the-arvr-market-43k5 | led, architecture, vr | The advancement of science and technology has gradually integrated various technologies into people's daily lives, realizing the concept of science and technology benefiting mankind. With the continuous updating of technology, many things that were previously impossible are gradually becoming a reality. The emergence and popularity of AR (augmented reality) and VR (virtual reality) are the manifestation of this trend. When you wander in the virtual ocean and talk to whales, or truly experience the magical time of the changing seasons in five minutes, AR/VR technology shows its magical side and brings users a new sensory world.
The rise of AR/VR technology and the rise of the “VR+LED” concept
In 2016, augmented reality and virtual reality technologies rose rapidly and became a hot topic in the technology world. Many companies have invested in this field, and technology giants such as Facebook, Microsoft and Google have demonstrated their latest achievements in AR/VR. Facebook launched the Oculus Rift for the masses and jointly released the Gear VR headset with Samsung. Google released the Daydream VR platform at the I/O conference. Faced with the enthusiasm of international companies, domestic companies are not to be outdone. iQiyi has launched a VR channel, Mango TV is trying to broadcast variety shows through VR technology, and applications such as VR house viewing are emerging one after another. [Let you understand the 10 major differences between XR technology and virtual production technology. ](https://www.sostron.com/service/faq/7385)
This craze has not only swept across industries such as the Internet, film and television, and games, but also promoted the construction concept of "VR + LED". High-definition LED displays provide better display effects for VR, and the realistic effects of VR also rely on LED displays as a carrier. The two complement each other and promote the development of the LED display industry. A Goldman Sachs research report predicts that the VR market is expected to reach US$80 billion by 2025, and up to US$182 billion under optimistic conditions. This development momentum allows the LED display industry to see huge potential. [Provide you with XR LED display product guide. ](https://sostron.com/news/6527)
How do LED display companies respond to the AR/VR market?
Although the AR/VR market has broad prospects, many LED display companies still maintain a wait-and-see attitude. The main reasons include technological challenges and market uncertainty. Here are a few key factors that companies need to consider when venturing into the AR/VR market:
Technical limitations and user experience:
The performance of small-pitch LED displays in VR applications is crucial, but current technology still faces some challenges. Small-pitch displays need to provide high-resolution, seamless, natural and realistic display effects. However, existing technology has not yet completely solved the problem of residual images, which may cause users to suffer from headaches and eye discomfort after watching for a long time. Companies need to invest a lot of money in technology research and development to improve the reliability and user experience of displays. [What is a fine-pitch LED display? ](https://www.sostron.com/service/faq/2756)
Cost and market penetration:
The cost of small-pitch LED displays is relatively high, which limits their popularity in the civilian market. In the display market below 60 inches, the price disadvantage of LED displays is particularly obvious. For example, the cost of producing a 40-inch small-pitch LED TV is close to 50,000 yuan, while an LCD TV of the same size sells for only a few thousand yuan. Companies need to find ways to reduce costs or develop high value-added commercial markets. [Provide you with commercial LED display price range. ](https://www.sostron.com/service/faq/7183)
Threats from competitors:
LED displays face challenges from competitors such as LCD displays and OLEDs in the VR field. LCD screens have obvious advantages in terms of cost performance, while OLEDs perform well in display effects. AMOLED technology has been applied to mobile devices and has become an important display carrier for VR access to mobile terminals. LED display companies need to find breakthroughs in technology and market strategies to gain an advantage in the competition. [Let’s take you through the seven major differences between LED and LCD panels. ](https://www.sostron.com/service/faq/7089)

1,866,044 | High-Frequency Trading Strategy Analysis - Penny Jump | High-frequency trading is a challenging and competitive field that relies on rapid trade execution... | 0 | 2024-05-27T02:18:03 | https://dev.to/fmzquant/high-frequency-trading-strategy-analysis-penny-jump-a22 | trading, strategy, analysis, fmzquant | High-frequency trading is a challenging and competitive field that relies on rapid trade execution and sensitive insights into the microstructure of the market. One notable strategy is Penny Jump, which focuses on exploiting "elephants" in the market to gain small but frequent profits. In this article, we will explain in detail how the Penny Jump strategy works, delving into the details of its code, so that beginners can understand how it operates.
### Understanding the Penny Jump Strategy
In the stock market, "elephants" usually refer to those institutional investors who wish to buy or sell a large number of shares but are unwilling to trade at market price. Instead, they choose to hang a large number of limit orders in the market, i.e., pending orders, to indicate their intentions. This behavior has attracted widespread attention in the market, because large transactions may have a significant impact on the market.
For example, suppose the original depth of a stock's market was like this: 200 | $1.01 x $1.03 | 200. Then an "elephant" enters and places a buy order for 3000 shares at $1.01 each. At this point, the depth of the market will change to 3,200 | $1.01 x $1.03 | 200 . This action is like introducing an "elephant", which becomes the focus of other participants in the marketplace.
- Competitive market
For high-frequency traders, their profits mainly come from the analysis of market microstructure to speculate on the intentions of other traders. Once a big player appears, high-frequency traders will establish positions quickly to capture minor price fluctuations. Their goal is to trade frequently in a short period of time and accumulate small but cumulative profits.
- The Dilemma of the Elephant
Even though elephants might wish to operate on a large scale in the market, their actions also reveal their trading intentions, making them targets for high-frequency traders. High-frequency traders attempt to establish positions ahead of time and then profit from price fluctuations. The presence of elephants in the market could trigger reactions in competitive markets, thereby affecting their trading strategies.
- Deception in the Market
In reality, large institutional investors usually do not place a large number of buy or sell orders in the market blatantly, as such behavior could lead other participants in the market to take countermeasures or even manipulate the market. Therefore, they may adopt strategies to create illusions, attract high-frequency traders into the field, and then quickly sell or buy to profit from price fluctuations.
### The Core Idea of the Penny Jump Strategy
The core idea of the Penny Jump strategy is that once a "big player" appears in the market and supports a specific price (such as $1.01), high-frequency traders will quickly raise their bid by one cent, for instance, to $1.02. This is because high-frequency traders understand that the appearance of a big player means there's strong buying support at this price level, so they try to follow closely in hopes of a price increase. When the price indeed rises to $1.03 x $1.05, high-frequency traders can sell quickly and earn a profit of $0.01.
Not only that, but high-frequency traders can also make profits after purchasing even if the price doesn't rise, because they know that the big player has supported the base price; hence they can swiftly sell their stocks to this big player and gain tiny arbitrage profits.
### Analyzing Penny Jump Strategy Code
Strategy source code: https://www.fmz.com/strategy/358
The strategy code provided above is an example, used to implement the Penny Jump strategy. Below is a detailed explanation of the code, enabling beginners to understand how it works:
```
var Counter = {
i: 0,
w: 0,
f: 0
};
// Variables
var InitAccount = null;
function CancelAll() {
while (true) {
var orders = _C(exchange.GetOrders);
if (orders.length == 0) {
break;
}
for (var i = 0; i < orders.length; i++) {
exchange.CancelOrder(orders[i].Id);
}
Sleep(Interval);
}
}
function updateStatus(msg) {
LogStatus("Number of debugging sessions:", Counter.i, "succeeded:", Counter.w, "failed:", Counter.f, "\n"+msg+"#0000ff\n"+new Date());
}
function main() {
if (DisableLog) {
EnableLog(false);
}
CancelAll();
InitAccount = _C(exchange.GetAccount);
Log(InitAccount);
var i = 0;
var locks = 0;
while (true) {
Sleep(Interval);
var depth = _C(exchange.GetDepth);
if (depth.Asks.length === 0 || depth.Bids.length === 0) {
continue;
}
updateStatus("Searching within the elephant... Buy one: " + depth.Bids[0].Price + ", Sell one:" + depth.Asks[0].Price + ", Lock times: " + locks);
var askPrice = 0;
for (i = 0; i < depth.Asks.length; i++) {
if (depth.Asks[i].Amount >= Lot) {
askPrice = depth.Asks[i].Price;
break;
}
}
if (askPrice === 0) {
continue;
}
var elephant = null;
// skip Bids[0]
for (i = 1; i < depth.Bids.length; i++) {
if ((askPrice - depth.Bids[i].Price) > ElephantSpace) {
break;
}
if (depth.Bids[i].Amount >= ElephantAmount) {
elephant = depth.Bids[i];
break;
}
}
if (!elephant) {
locks = 0;
continue;
}
locks++;
if (locks < LockCount) {
continue;

```
I will parse your provided strategy code line by line to help you understand its operation in detail.
```
var Counter = {
i: 0,
w: 0,
f: 0
};
```
This code initializes an object named Counter, which is used to track the trading statistical information of a strategy. Specifically, it includes three attributes:
- i: Represents the total number of transactions.
- w: Represents the number of successful transactions.
- f: Represents the number of failed transactions.
These attributes will be recorded and updated during the strategy execution process.
```
var InitAccount = null;
```
This line of code initializes a variable named InitAccount, which will store account information when the strategy starts executing.
```
function CancelAll() {
while (true) {
var orders = _C(exchange.GetOrders);
if (orders.length == 0) {
break;
}
for (var i = 0; i < orders.length; i++) {
exchange.CancelOrder(orders[i].Id);
}
Sleep(Interval);
}
}
```
This is a function named CancelAll(), its purpose is to cancel all unfulfilled orders in the market. Let's explain its functions step by step:
- while (true): This is an infinite loop, it will continue to run until there are no uncompleted orders.
- var orders = _C(exchange.GetOrders): This line of code uses the exchange.GetOrders function to retrieve all pending orders in the current account and stores them in the orders variable.
- if (orders.length == 0): This line of code checks for any unfinished orders. If the length of the orders array is 0, it means there are no unfinished orders and the loop will be interrupted (break).
- for (var i = 0; i < orders.length; i++): This is a for loop that iterates through all uncompleted orders.
- exchange.CancelOrder(orders[i].Id): This line of code uses the exchange.CancelOrder() function to cancel each order by its ID.
- Sleep(Interval): This line of code introduces a waiting period, pausing for a certain amount of time (in milliseconds), to ensure that the operation of cancelling orders is not too frequent.
This line of code introduces a waiting period, pausing for a certain amount of time (in milliseconds), to ensure that the operation of cancelling orders is not too frequent.
```
function updateStatus(msg) {
LogStatus("Number of debugging sessions:", Counter.i, "succeeded:", Counter.w, "failed:", Counter.f, "\n" + msg + "#0000ff\n" + new Date());
}
```
This is a function named updateStatus(msg), which is used to update and record transaction status information. It accepts a msg parameter, which usually contains information about the current market status. The specific operations of the function include:
Using the LogStatus() function to record the information displayed in the status bar during strategy execution. It displays text about trade counts, successful counts, and failure counts.
The msg parameter is appended, which contains information about the current market status.
The current timestamp (new Date()) is appended to display time information.
The purpose of this function is to record and update transaction status information for monitoring and analysis during strategy execution.

```
This is the main execution function main() of the strategy, which contains the core logic of the strategy. Let's explain its operations line by line:
- if (DisableLog): This line of code checks if the DisableLog variable is true, and if so, it will disable log recording. This is to ensure that unnecessary logs are not recorded by the strategy.
- CancelAll(): Call the previously explained CancelAll() function to ensure that there are no unfinished orders.
- InitAccount = _C(exchange.GetAccount): This line of code retrieves the current account information and stores it in the InitAccount variable. This will be used to record the account status when the strategy starts executing.
- var i = 0; and var locks = 0;: Initialize two variables, i and locks, which will be used in the subsequent strategy logic.
- while (true): This is an infinite loop, mainly used for the continuous execution of strategies.
Next, we will explain the main strategy logic within the while (true) loop line by line.
```
while (true) {
Sleep(Interval);
var depth = _C(exchange.GetDepth);
if (depth.Asks.length === 0 || depth.Bids.length === 0) {
continue;
}
updateStatus("Searching within the elephant... Buy one: " + depth.Bids[0].Price + ", Sell one:" + depth.Asks[0].Price + ", Lock times: " + locks);
```
- Sleep(Interval): This line of code allows the strategy to sleep for a period of time, in order to control the execution frequency of the strategy. The Interval parameter defines the sleep interval (in milliseconds).
- var depth = _C(exchange.GetDepth): Obtain the current market depth information, including the prices and quantities of sell orders and buy orders. This information will be stored in the depth variable.
- if (depth.Asks.length === 0 || depth.Bids.length === 0): This line of code checks the market depth information, ensuring that both sell orders and buy orders exist. If one of them does not exist, it indicates that the market may not have enough trading information, so the strategy will continue to wait.
- updateStatus("Searching within the elephant... Buy one: " + depth.Bids[0].Price + ", Sell one:" + depth.Asks[0].Price + ", Lock times: " + locks): This line of code calls the updateStatus function to update the status information of the strategy. It records the current market status, including the highest bid price, lowest ask price and previously locked times (locks).
```
var askPrice = 0;
for (i = 0; i < depth.Asks.length; i++) {
if (depth.Asks[i].Amount >= Lot) {
askPrice = depth.Asks[i].Price;
break;
}
}
if (askPrice === 0) {
continue;
}
var elephant = null;
```
- var askPrice = 0;: Initialize the askPrice variable, it will be used to store the price of sell orders that meet the conditions.
- for (i = 0; i < depth.Asks.length; i++): This is a for loop used to traverse the price and quantity information of market sell orders.
- if (depth.Asks[i].Amount >= Lot): In the loop, check if the quantity of each sell order is greater than or equal to the specified Lot (hand count). If so, store the price of that sell order in askPrice and terminate the loop.
- if (askPrice === 0): If no sell orders that meet the conditions are found (askPrice is still 0), the strategy will continue to wait and skip subsequent operations.
- var elephant = null;: Initialize the elephant variable, it will be used to store the buy order information identified as "elephant".
```
for (i = 1; i < depth.Bids.length; i++) {
if ((askPrice - depth.Bids[i].Price) > ElephantSpace) {
break;
}
if (depth.Bids[i].Amount >= ElephantAmount) {
elephant = depth.Bids[i];
break;
}
}
if (!elephant) {
locks = 0;
continue;
}
locks++;
if (locks < LockCount) {
continue;
}
locks = 0;
```
Continue to traverse the price and quantity information of market buy orders, skipping the first buy order (Bids[0]).
- if ((askPrice - depth.Bids[i].Price) > ElephantSpace): Check whether the gap between the current bid price and askPrice is greater than ElephantSpace. If so, it indicates that it is far enough from the "elephant", and the strategy will no longer continue to search.
- if (depth.Bids[i].Amount >= ElephantAmount): Check if the quantity of the current buy order is greater than or equal to ElephantAmount. If so, store the buy order information in the elephant variable.
- if (!elephant): If the "elephant" is not found, reset the lock count to 0 and continue waiting.
- locks++: If the "elephant" is found, increment the lock count. This is to ensure that the strategy is executed only after confirming the existence of the "elephant" multiple times over a period of time.
- if (locks < LockCount): Check whether the number of lock times has met the requirement (LockCount). If it hasn't, continue to wait.
```
updateStatus("Debug the elephant... The elephant is in gear " + i + ", " + JSON.stringify(elephant));

for (var i = 0; i < orders.length; i++) {
exchange.CancelOrder(orders[i].Id);
}
}
}
```
- updateStatus("Debug the elephant... The elephant is in gear " + i + ", " + JSON.stringify(elephant)): Call the updateStatus function to record the current status of the strategy, including the gear position of the "elephant" found and related information. This will be displayed in the status bar of the strategy.
- exchange.Buy(elephant.Price + PennyTick, Lot, "Bids[" + i + "]", elephant): Use the exchange.Buy function to purchase the found "elephant". The purchase price is elephant.Price + PennyTick, the purchase quantity is Lot, and describe the purchase operation as "Bids[" + i + "]".
- var ts = new Date().getTime(): Obtain the timestamp of the current time for subsequent calculation of time intervals.
- while (true): Enter a new infinite loop, used to wait for the execution of "elephant" buy orders.
- Sleep(CheckInterval): The strategy sleeps for a while to control the frequency of checking order status.
- var orders = _C(exchange.GetOrders): Obtain all order information of the current account.
- if (orders.length == 0): Check if there are any unfinished orders, if not, break the loop.
- (new Date().getTime() - ts) > WaitInterval: Calculate the time interval between the current time and when the "elephant" was purchased. If it exceeds WaitInterval, it means that the waiting has timed out.
- for (var i = 0; i < orders.length; i++): Traverse through all uncompleted orders.
- exchange.CancelOrder(orders[i].Id): Use the exchange.CancelOrder function to cancel each unfinished order.
```

Counter.f++;
}
Counter.i++;
var account = _C(exchange.GetAccount);
LogProfit(account.Balance - InitAccount.Balance, account);
}
```
- var account = _C(exchange.GetAccount): Obtain current account information.
- var opAmount = _N(account.Stocks - InitAccount.Stocks): Calculate the change in account assets after purchasing the "elephant". If the change is less than 0.001, it indicates that the purchase has failed, increase the number of failures and continue to the next loop.
- updateStatus("Successful payment: " + opAmount + ", Start taking action..."): Record the successful purchase information of "elephant", including the quantity purchased.
- exchange.Sell(elephant.Price + (PennyTick * ProfitTick), opAmount): Use the exchange.Sell function to sell the successfully purchased "elephant" for profit. The selling price is elephant.Price + (PennyTick * ProfitTick).
Enter a new infinite loop, used to wait for the execution of sell orders.
- var depth = _C(exchange.GetDepth): Obtain market depth information.
- if (depth.Bids.length > 0 && depth.Bids[0].Price <= (elephant.Price - (STTick * PennyTick))): Check the market depth information, if the market price has already fallen to the stop-loss level, then execute the stop-loss operation.
- CancelAll(): Call the CancelAll() function to cancel all uncompleted orders, in order to avoid position risk.
- if (opAmount < 0.001): Check the purchase quantity again, if it's less than 0.001, it indicates that the purchase has failed, break out of the loop.
- exchange.Sell(depth.Bids[0].Price, opAmount): Execute a stop-loss operation, sell the remaining assets at the current market's lowest price.
Finally, update the number of successful and failed transactions based on whether the transaction was successful or not, and record the trading profits.
This is a line-by-line explanation of the entire strategy. The core idea of this strategy is to find "elephants" (large buy orders) in the market, buy and sell them to gain small profits. It includes several important parameters, such as Lot, error retry interval (Interval), ElephantAmount, ElephantSpace, etc., to adjust the strategy.
In general, this strategy is a high-frequency trading strategy aimed at utilizing market depth information to identify large buy orders and carry out buying and selling transactions in a short period. It needs constant monitoring of the market and execution of buying and selling operations to quickly gain small profits. However, it's also a high-risk strategy, because it requires quick responses to market fluctuations while considering risk management and stop-loss mechanisms to avoid significant losses.
Please note that the strategy is based on specific markets and trading platforms. For different markets and exchanges, appropriate adjustments and optimizations may be needed. In practical application, investors need to carefully test and evaluate the performance of the strategy to ensure it aligns with their investment goals and risk tolerance.
As you continue to execute the strategy, it will repeatedly perform the following operations:
1. Firstly, the strategy will check the depth information of the market to understand the current situation of sell orders and buy orders.
2. Next, the strategy will attempt to find sell orders that meet the criteria, specifically sell orders with a quantity greater than or equal to Lot. If a qualifying sell order is found, the price of the sell order will be recorded as askPrice.
3. Then, the strategy will continue to search for "elephants" (large amount of buy orders). It will traverse through the market's buy orders, skipping the first one (usually the highest-priced buy order). If it finds an "elephant" that meets the criteria, it will record information about the "elephant", and increase locks.
4. If a sufficient number of "elephants" are found consecutively (controlled by the LockCount parameter), the strategy will further perform the following operations:
- Call the updateStatus function to record the gear and related information of the "elephant".
- Use the exchange.Buy function to purchase an "elephant", with a purchase price of elephant.Price + PennyTick, and a quantity of Lot.
- Start a new infinite loop for waiting for execution of the buy order.
- Check order status. If it is completed, break out from loop.
- If waiting time exceeds set interval (WaitInterval), cancel all uncompleted orders.
- Calculate changes in account assets after successful purchase. If change is less than 0.001, it indicates that purchase failed; increase failure count and continue next loop.
- Record information about successful purchases of "elephants", including quantity purchased.
5. Next, the strategy will continue to enter a new infinite loop, waiting for the execution of sell operations. In this loop, it will perform the following actions:
- Obtain market depth information, check if the market price has already reached the stop-loss level.
- If the market price has reached or fallen below the stop-loss level, a stop-loss operation will be executed, that is, the remaining assets will be sold.
- Call the CancelAll function to cancel all uncompleted orders, reducing position risk.
- Recheck the change in account assets after a successful purchase. If the change is less than 0.001, it indicates that the purchase has failed and exit the loop.
- Finally, record whether the transaction is successful or not, and update the number of successes and failures based on the transaction results.
The entire strategy continuously carries out the above operations to capture as many "elephants" as possible and obtain small profits. This is a high-frequency trading strategy that requires quick responses to market changes, while also considering risk management and stop-loss mechanisms to protect capital. Investors should carefully consider using this strategy, especially in highly volatile markets.
### Summary
The Penny Jump strategy is a typical example in high-frequency trading, demonstrating the subtle game and competition among market participants. This strategy is particularly prominent in the cryptocurrency market due to its large fluctuations, where institutional investors and high-frequency traders are all pursuing quick profits. However, this also makes the market full of challenges, requiring constant adaptation and adjustment of strategies to maintain competitive advantages. In this fiercely competitive world, only those traders who are good at discerning the microstructure of the market and responding quickly can achieve success.

1,862,314 | What Are The Uses of JavaScript | JavaScript is one of the core technologies of the web, alongside HTML which is a markup language and... | 0 | 2024-05-27T02:17:00 | https://dev.to/thekarlesi/what-are-the-uses-of-javascript-32io | webdev, javascript, beginners, programming | JavaScript is one of the core technologies of the web, alongside HTML which is a markup language and is used to structure web page content, and CSS which is used to style that content.
So, JavaScript is what brings life to the front-end or the user interface of a website or a web app. It allows us to make web pages dynamic.
Not only that, but it can also be used on the server-side to do things like interact with databases and work with the files system. This is with the help of the Node.js runtime.
So, JavaScript is a high-level interpreted programming language, used to create interactive and dynamic website experiences.
When I say interpreted, what I mean is that it is executed line by line rather than being compiled into machine code first. So, the code is first executed on the fly making the scripting language, hence the name JavaScript.
I am going to answer the following four commonly asked questions in this introduction.
The questions are:
1. What is JavaScript?
2. What can you do with it?
3. Where does JavaScript code run?
4. And the difference between JavaScript and ECMAScript?
Before we begin, an announcement. I am accepting new students to join [The 2 Hour Web Developer Course](https://karlgusta.gumroad.com/l/eofdr/680bkf4). Join before enrollment closes.
So, let's start with the first question.
## What is JavaScript
JavaScript is one of the most popular and widely used programming languages in the world right now. It is growing faster than any other programming language and big companies like Netflix, Walmart, and PayPal build entire applications around JavaScript.
And here is the average salary of a JavaScript developer in the United States. That is $72,000 per year according to glassdoor.com.
So, it is a great opportunity to get a good job out of learning JavaScript. You can work as a front-end developer, a back-end developer or a full stack developer who knows both the front end and the back end.
Now the second question.
## What can you do with JavaScript
For a long time, JavaScript was only used in browsers to build interactive web pages. Some developers refer to JavaScript as a toy language. But those days are gone because of huge community support and investments by large companies like Facebook and Google.
This days, you can build full-blown web or mobile apps, as well as real time networking applications like chat and video streaming services, command-line tools, or even games. Here is an example:
The third question.
## Where does JavaScript code run?
JavaScript was designed to run only in browsers so every browsers has what we call a JavaScript engine that can execute JavaScript code.
For example, the JavaScript engines in Firefox and Chrome are SpiderMonkey and V8.
In 2009, a very clever engineer called Ryan Dahl took the open-source JavaScript engine in Chrome and embedded it inside a C++ program. He called that program, node.
Node is a C++ program that includes Google's V8 JavaScript engine. Now with this, we can run JavaScript code out of a browser. So, we can pass our JavaScript code to node for execution. This means, with JavaScript, we can build the backend for our web and mobile applications.
So, in a nutshell, JavaScript code can be run inside of a browser, or in node. Browsers and node provide a runtime environment for our JavaScript code.
Finally, the last question.
## What is the difference between JavaScript and ECMAScript
Well, ECMAScript is just a specification. JavaScript is a programming language that conforms to this specification. So, we have this organization called ECMA which is responsible for defining standards. They take care of this ECMAScript specification.
The first version of ECMAScript was released in 1997. Then starting from 2015, ECMA has been working on annual releases of a new specification.
So, in 2015, they released ES2015/2016 which is also called ECMA Script version 6 or ES6 for short.
This specification defined many new features for JavaScript.
Alright! Enough theory, let's see JavaScript in action.
So, every browser has a JavaScript engine and we can easily write JavaScript code here without any additional tools. Of course, this is not how we build real-world applications, but this is just for a quick demo.
So, open up Chrome, right click on an empty area, and go to inspect.
Now, this opens up Chrome Developer Tools.
Here, select the Console tab,
This is our JavaScript console and we can write any valid JavaScript code here.
So, type this:
```javascript
console.log('Hello World');
```
Now, as we go through out the course, you are going to understand exactly what all this means. For now, don't worry about it.
So now, press ENTER and you can see the Hello World message on the console.
We can also write mathematical expressions here. For example,
```js
2+2
4
```
Or, we can do something like this
```js
alert('yo')
```
You press ENTER, and you get an alert
In the next section, I am going to talk about how to set up your environment for writing JavaScript code.
## Setting Up the Environment for Writing JavaScript code
In order to write JavaScript code, you need a code editor. There are various code editors out there, including:
- Visual Studio Code(VS Code)
- Sublime Text
- Atom and so on.
Out of this, my favorite is Visual Studio Code, that you can download from `code.visualstudio.com`.
It is a very simple, light-weight, cross-platform, and powerful editor.
So, if you don't have Visual Studio Code on your machine, go ahead and download it.
The other thing I want you to install is Node.
You can download node from `nodejs.org`
Now, technically, you don't need Node to execute JavaScript. Because, as I explained before, you can execute JavaScript code, inside of a browser, or in Node. But, it is good to have Node on your machine, because we use that to install third-party libraries.
Also, later in this section, I am going to show you a preview of Node.
So, stop reading now and install Visual Studio as well as Node. Once you are done, come back and continue reading.
Now, I want you to create a new folder. Call the folder `js-basics`
The name really doesn't matter. We just want to have a folder, for writing all the code in this course. Now, drag and drop this folder into Visual Studio Code.
Now, we have this folder open. Let's add a new file here, `index.html`
You don't really need to know HTML in order to take this course, but if you want to be a Frontend developer, you should know your HTML well.
Now, in this file, I need you to type an `!` exclamation and then press TAB.
This generates some basic HTML boiler plate.
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial- scale=1.0">
<title>Document</title>
</head>
<body>
</body>
</html>
```
We don't really care about any of this code here. We are going to use this as a host for our JavaScript code.
We are going to see that in the next lecture.
So, save the changes, open the extensions tab, here.
Here on this box, search for `live server`.
So, live server, is a very light-weight web server that we are going to use to serve our web application.
So, install this, then we are going to restart our Visual Studio Code.
When you are done, go to the explorer tab, right click `index.html`, and select `open with Live Server`
This will open up Chrome, or your default browser, and point it to this address, `127.0.0.1:5500/index.html`
That is where, our web application is served from.
Currently, we have an empty page. Now, to make sure that everything is working properly, let's go back to Visual Studio Code.
Here in the body section, let's add an `<h1>`
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial- scale=1.0">
<title>Document</title>
</head>
<body>
<h1>Hello World</h1>
</body>
</html>
```
Now, save the changes. Back in the browser, we can see this page is refreshed automatically, and we have the Hello World heading here.

It's a trying moment, full of emotional tension and difficult decisions. If you're going through a divorce in Grand Rapids, having a competent and sympathetic divorce lawyer on your side may make a huge difference. This article will look at the job of a Grand Rapids divorce lawyer and how they may help you through this difficult time.
## Understanding the Role of a Divorce Lawyer
A divorce lawyer specializes in family law and can handle all the proceedings. Their primary purpose is to represent your interests and assist you in getting the best possible conclusion. Here are some important ways a divorce lawyer might help you:
**Legal Advice and Guidance**
Different states have different divorce rules that can be hard to understand. A divorce lawyer in Grand Rapids will provide clear and correct legal help. To help you know what to expect during the process, they will tell you what your rights and duties are.

The divorce procedure entails a great deal of documentation. From submitting the first divorce petition to preparing agreements and court papers, your lawyer will ensure all documentation is completed accurately and on schedule. This reduces delays and guarantees that legal regulations complete everything.
**Negotiation and Mediation**
In a divorce, there are often talks about how to divide assets, who cares for the kids, and how to pay child support. During these talks, a good divorce lawyer will seek your best interests and try to reach a fair deal. If needed, they can also help with mediation, which is when a third party who is not involved in the dispute helps both sides come to an understanding.
## Why Choose a Grand Rapids Divorce Lawyer?
**Local Expertise**
Choosing a lawyer conversant with the local legal scene might provide considerable benefits. A [Grand Rapids divorce lawyer](https://www.kraayeveld.com/divorce/) is familiar with Michigan's divorce laws and has dealt with local courts and judges before. This local experience can help you shorten the process and better understand your issue.

Se puder, já deixa um like ou comentário aí pra me ajudar! o/
O Google SafeSearch é um serviço do Google Cloud que consiste em receber uma imagem de entrada e prover uma análise em busca de conteúdo sensível nesta imagem.
Diferente de alguns serviços, o SafeSearch analisa a imagem em alguns pontos fundamentais:
- Nudez, imagens de atos sexuais ou material com conteúdo sexual explícito;
- Violência e imagens sangrentas.
Além de analisar a sua imagem, o serviço provê um retorno contendo 5 categorias de análise e quais os níveis encontradas na imagem analisada:
**Exemplo de response:**
`{
"responses": [
{
"safeSearchAnnotation": {
"adult": "UNLIKELY",
"spoof": "VERY_UNLIKELY",
"medical": "VERY_UNLIKELY",
"violence": "LIKELY",
"racy": "POSSIBLE"
}
}
]
}`
O retorno acima demonstra em qual categoria e nível de sensibilidade foi encontrado em uma imagem na análise. Os níveis são: **VERY_UNLIKELY, POSSIBLE, LIKELY, VERY_LIKELY.**
No exemplo acima, o algoritmo do SafeSearch detectou "**LIKELY**" para conteúdo violento. Em testes com imagens reais, o nível LIKELY já continha realmente coisas sensíveis, já o POSSIBLE seriam coisas leves, mas nada muito explícito. Geralmente depende do critério do cenário em que você irá utilizar, por exemplo se você estiver analisando imagens de um convento, talvez o POSSIBLE seria um problema. Mas se você estiver usando em um cenário de um app de relacionamento, nem tanto.
## UTILIZANDO NA PRÁTICA
Como algumas pessoas sabem, sou CEO e Fundador de um aplicativo de relacionamento em constante crescimento que se chama Denga Love. Como sou um CEO com background técnico (raridade por aí), alguns produtos eu mesmo assumo a frente pra teste técnico de validação se a ferramente é útil pro nosso cenário.
**Problema:** usuários colocando em seus perfis fotos ultra sensíveis: partes genitais, armas de fogo, fraturas expostas e coisas do tipo.
Quem usa aplicativos de relacionamento, sabe o quanto é importante o uso de fotos de boa qualidade. Logo, fotos com conteúdos sensíveis não somente afetam negativamente a pessoa que utilizou a foto, mas toda a rede. Neste caso, se faz necessário o uso de tecnologias de apoio na detecção destas imagens.
**Configurando o projeto:**
Inicialmente, é necessário ter ativado a Cloud Vision API:
Logo após, você já terá autorização de uso da API do SafeSearch e de outras mais, como a de OCR, detecção facial e outras...
**Configurando e utilizando a API:**
Configure o SDK do Google Cloud no seu computador ou crie uma conta de serviço para poder usar a API. [Neste link](https://cloud.google.com/docs/authentication/provide-credentials-adc?hl=pt-br#local-dev) tem um tutorial rápido.
Finalmente, [neste link](https://cloud.google.com/vision/docs/detecting-safe-search#vision_safe_search_detection_gcs-gcloud) você encontra exemplos de uso que irão desde no via curl e até com Node, Python, etc...
**Teste 1:** uma imagem minha no Google IO Connect, em Miami.
**Retorno 1:** retorno real do SafeSearch para essa imagem
Perceba que nada de sensível foi detectado em nenhuma das categorias.
**Teste2:** imagem de coleta sanguínea
**Retorno2:** O SafeSearch detectou "POSSIBLE" para a maioria dos casos
**Custos:** A API do SafeSearch é gratuita até 1000 requisições para a API. Convém olhar os custos antes caso seu uso previsto seja maior.
**Aviso importante:** decidi não colocar aqui fotos mais sensíveis que essas pois fico imaginando que isso poderiam causar algum mal estar em quem estiver lendo. Estamos falando de imagem de pessoas mostrando a genitália para coisas piores. É melhor não mostrar, não é mesmo?
**Considerações Finais:**
Gostaria muito que mais pessoas conhecessem o SafeSearch, pois fico vendo muitas pessoas treinarem seus próprios algoritmos para resolver problemas semelhantes. Particularmente, sou do time que procura algo pronto sempre e só gastaria tempo e dinheiro criando uma IA para esse fim se realmente nenhuma me atendesse em nada ou se fosse muito mais caro utilizar a API do que criar a própria. Neste caso, os custos são baixos e a qualidade é muito boa.
Outro ponto importante é que a depender do seu uso, essa API irá retornar POSSIBLE ou LIKELY para coisas que não são nem de perto um problema. Encontrei esse problema com imagens de pessoas negras em cenário de baixo qualidade da imagem ou ambiente muito escurecido, mas foram raros casos. Por isso, sugiro considerar os resultados apenas a partir do LIKELY (quando é sensível mas em geral não explícito) ou VERY_LIKELY (onde é realmente algo muito sensível e explícito).

1,866,035 | Quantum Algorithm Implementation: Finding the Best Deals | Introduction The similarity between the rich and the poor is that both love a good... | 0 | 2024-05-27T01:30:03 | https://dev.to/supreethmv/finding-the-best-deals-smart-shopping-with-quantum-algorithms-1na4 | programming, ai, algorithms, quantumcomputing |
## Introduction
The similarity between the rich and the poor is that both love a good bargain—just at different stores. Whether you’re shopping at Louis Vuitton or a local flea market, everyone is on the lookout for the best deals. But what if you could use cutting-edge technology to optimize your shopping experience?
Imagine trying to bundle purchases to maximize discounts, but the options are so numerous, forget about manually evaluating each one, it's impossible even for today's supercomputers. However, this problem can be tackled using quantum computing, specifically with the BILP-Q algorithm. Let's dive into how this works.
## Understanding the Basics
### What is the Problem?
Think of this as a shopping challenge. You have four items to buy: a webcam, shoes, headphones, and socks. Each item or combination of items has a different discount. The goal? Find the best combination of bundles to minimize your total cost.
### Classical Approach vs. Quantum Approach:
Traditionally, solving this involves evaluating all possible combinations of items, which quickly becomes impractical as the number of items increases. This is a classical NP-Hard problem in AI called the Coalition Structure Generation (CSG) problem which has vital applications in cooperative game theory, multi-agent systems, and microeconomics.
Quantum computing, however, can handle this complexity more efficiently.
## Introducing BILP-Q
### What is BILP-Q?
BILP-Q stands for Binary Integer Linear Programming - Quantum. It transforms our shopping problem into a Quadratic Unconstrained Binary Optimization (QUBO) problem, which quantum computers can solve effectively using algorithms like Quantum Approximate Optimization Algorithm (QAOA).
## Example Scenario
Imagine you want to buy four items: a webcam, shoes, headphones, and socks. Here’s how the discounts for different bundles look:
### Single items:
- Webcam: $30
- Shoes: $40
- Headphones: $25
- Socks: $15
### Bundles of two items:
- Webcam & Shoes: $50
- Webcam & Headphones: $40
- Webcam & Socks: $50
- Shoes & Headphones: $55
- Shoes & Socks: $45
- Headphones & Socks: $45
### Bundles of three items:
- Webcam, Shoes & Headphones: $90
- Webcam, Shoes & Socks: $95
- Webcam, Headphones & Socks: $75
- Shoes, Headphones & Socks: $85
### All four items:
- Webcam, Shoes, Headphones & Socks: $105
Your goal is to buy all four items with the maximum discount.
For formal definitions of the problem and mathematical details, please refer to the original paper of [BILP-Q](https://dl.acm.org/doi/10.1145/3528416.3530235).
## Visual Representation of the solution space
The following diagram shows all possible ways to purchase the four items, along with their total costs. Each level represents a different number of groups (coalitions).
Manually checking each possible combination is tedious, so we use BILP-Q to find the optimal solution.
## Walkthrough of the Example
### Setting Up the Problem:
#### Install qiskit
```
pip install qiskit
pip install qiskit_optimization
```
#### Clone/download the [BILP-Q official repository](https://github.com/supreethmv/BILP-Q) and import the below python scripts:
```
import Utils_Solvers
import Utils_CSG
```
#### Define the Problem Instance:
We will enumerate the items as follows:
1 for Webcam,
2 for Shoes,
3 for Headphones, and
4 for Socks.
Here’s how you can initialize the values of the bundles:
```
# Define the cost of each bundle
coalition_values = {
'1': 30,
'2': 40,
'3': 25,
'4': 15,
'1,2': 50,
'1,3': 40,
'1,4': 50,
'2,3': 55,
'2,4': 45,
'3,4': 45,
'1,2,3': 90,
'1,2,4': 95,
'1,3,4': 75,
'2,3,4': 85,
'1,2,3,4': 105
}
```
### Convert to BILP:
We convert the CSG problem to a Binary Integer Linear Programming (BILP) problem:
```
c, S, b = Utils_CSG.convert_to_BILP(coalition_values)
```
### Convert to QUBO:
Next, we convert the BILP problem to a Quadratic Unconstrained Binary Optimization (QUBO) problem:
```
import numpy as np
qubo_penalty = 50 * -1
linear, quadratic = Utils_CSG.get_QUBO_coeffs(c, S, b, qubo_penalty)
Q = np.zeros([len(linear), len(linear)])
# Diagonal elements
for key, value in linear.items():
Q[int(key.split('_')[1]), int(key.split('_')[1])] = value
# Non-diagonal elements
for key, value in quadratic.items():
Q[int(key[0].split('_')[1]), int(key[1].split('_')[1])] = value / 2
Q[int(key[1].split('_')[1]), int(key[0].split('_')[1])] = value / 2
```
### Solving QUBO Using QAOA:
We use QAOA to solve the QUBO problem:
```
#@title Default title text
backend = BasicAer.get_backend('qasm_simulator')
optimizer = COBYLA(maxiter=100, rhobeg=2, tol=1.5)
qubo = create_QUBO(linear, quadratic)
p=1
init = [0.,0.]
qaoa_mes = QAOA(optimizer=optimizer, reps=p, quantum_instance=backend, initial_point=init)
qaoa = MinimumEigenOptimizer(qaoa_mes) # using QAOA
qaoa_result = qaoa.solve(qubo)
solution = qaoa_result.x
print(f'Solution: {solution}')
```
### Decoding the Solution:
The solution `x` is a binary string of size {% katex inline %} 2^n - 1 {% endkatex %}, where each bit represents a non-empty subset of the items and the positions marked `1` will be considered. For four items, the subsets are:
1. Webcam
2. Shoes
3. Headphones
4. Socks
5. Webcam, Shoes
6. Webcam, Headphones
7. Webcam, Socks
8. Shoes, Headphones
9. Shoes, Socks
10. Headphones, Socks
11. Webcam, Shoes, Headphones
12. Webcam, Shoes, Socks
13. Webcam, Headphones, Socks
14. Shoes, Headphones, Socks
15. Webcam, Shoes, Headphones, Socks
For example, the solution is obtained will look like `000001001000000`.
Parsing the binary string from left to right, we select the 6th subset {Webcam, Headphones} and the 9th subset {Shoes, Socks} as the optimal bundles to purchase.
### Visualizing the Quantum Circuit
Finally, display the quantum circuit used in QAOA:
```
qaoa_mes.get_optimal_circuit().draw('mpl')
```
## The Challenge of the Problem
Although this is a very hard problem, the size of the input is also exponential compared to the number of agents (items in this case). For {% katex inline %} n=4 {% endkatex %} items, the input was a dictionary of prices for each possible bundle, which totals {% katex inline %} 2^n−1 = 2^4−1=15 {% endkatex %}.
Thus, in the next post, we will explore induced subgraph games, where the problem setting is more practical, but the complexity of finding the optimal solution is still hard for classical computers.
## Conclusion
In this post, we explored how a quantum algorithm can tackle complex optimization problems efficiently. We have modeled a very primitive scenario while the actual problem is based on intelligent agents and typically not items. There are more realistic coalition formation use-cases that can be implemented such as peer-to-peer energy trading, logistics, wireless sensor networks and see how quantum computing can simplify the decision-making process.
Quantum computing is still emerging, but its potential to solve complex optimization problems is immense. As quantum technology advances, we can expect more efficient solutions to problems that are currently infeasible for classical computers.

## What I Built
<!-- Tell us what your app does! -->
I developed in Angular a small application serving as a backoffice for a site selling pets. The idea here is to provide registered information on the platform about a pet and its seller, commonly called the owner.
To be able to use the application, authentication by password/username (email) is necessary, the user can create one if they do not have one. Once the user is connected, he records the information on the owner of the animal, then records the pets one by one by selecting an owner from the previously created list.

## Integrations
<!-- Tell us which qualifying technologies you integrated, and how you used them. -->
The following AWS services have been integrated:
- S3
- AppSync
- Lambda
- Dyanmodb
- Cognito/IAM
## 1. Serverless DynamoDB & AppSync
All data entered by users is saved in a Dynamodb table. Here is the table schema and the amplify configuration:
```ts
export const petsSchema = {
PetOwner: a
.model({
OwnerID: a.id(),
Name: a.string().required(),
Email: a.email().required(),
Phone: a.string(),
Bio: a.string(),
Picture: a.string(),
})
.authorization((allow) => allow.publicApiKey()),
PetKind: a.enum(['FEMALE', 'MALE']),
PetCategorySchema: a.enum(
Object.keys(PetCategory).filter((v) => isNaN(v as any))
),
Pet: a
.model({
ID: a.id(),
NickelName: a.string().required(),
Price: a.float().required(),
Category: a.ref('PetCategorySchema').required(),
Breed: a.string(),
Rate: a.float().default(0.0),
Kind: a.ref('PetKind'),
BornDate: a.date().required(),
Weight: a.float().required(),
PetBio: a.string(),
OwnerID: a.id(),
//Owner: a.belongsTo('PetOwner', 'OwnerID'),
Images: a.string().array(),
DefaultImage: a.string(),
})
.authorization((allow) => allow.publicApiKey()),
};
```
## 2. S3
For storing the pets' images and the owners photo, I used S3 storage service. How did I store the images in S3? when registering the pet our owner, I make a first record in the DynamoDB table to get the _ID, then I upload the file(s) to the S3 bucket then I update the information with the file ObjectKey.
> amplify/s3 configuration
```ts
export const storage = defineStorage({
name: 'amplifyPetShop',
triggers: {...}),
},
access: (allow) => ({
'owner-pictures/*': [
allow.guest.to(['read']),
allow.authenticated.to(['read', 'delete', 'write']),
],
'pets-thumbs/*': [
allow.guest.to(['read']),
allow.resource(createImageThumbs).to(['read', 'write', 'delete']),
allow.entity('identity').to(['read', 'write', 'delete']),
],
'pets/*': [
allow.guest.to(['read']),
allow.resource(createImageThumbs).to(['read']),// Lambda resource
allow.entity('identity').to(['read', 'write', 'delete']),
],
}),
});
```
```ts
const files =...; // <-- list of File
const prefix = "pets";
const arr = [...files].map((file) =>
from(
uploadData({
data: file,
path: `${prefix}${uuid}_${file.name}`,
}).result.then((result) => ({ result, original: file.name }))
)
);

## 3. Serverless Lambda
I. n order to automate the creation of images in miniaturized versions (thumbnails) at a lower cost, I opted for a lambda which is triggered each time a file is loaded in the *Pets* folder, this lambda executes a function which generates a thumbnail image and it in turn loads it into S3 bucket. Here is the amplify configuration and code for the function in question.
> Amplify onfiguration
```ts
export const createImageThumbs = defineFunction({
name: 'gen-image-thumbs',
entry: './handler.ts',
runtime: 20,
memoryMB: 256,
});
```
> and the lambda function code
```ts
export const handler: S3Handler = async (event: S3Event) => {
const objectKeysUploaded = event.Records.map(
(record: any) => record.s3.object.key
);
const srcBucket = process.env.AMPLIFY_PET_SHOP_BUCKET_NAME;
const srcKey = event.Records[0].s3.object.key;
if (srcKey.startsWith('pets/')) {
const dstKey = `pets-thumbnails/${srcKey.split('pets/')[1]}`;
const originalImage = await s3Client.send(
new GetObjectCommand({
Bucket: srcBucket,
Key: dstKey,
})
);
// @ts-ignore
const resizedImage = await sharp(originalImage).resize(128).toBuffer();
const command = new PutObjectCommand({
Bucket: srcBucket,
Key: `thumbnails/${objectKeysUploaded[0]}`,
Body: resizedImage,
});
await s3Client
.send(command)
.then((value) => {
console.log(`Thumbnail uploaded for objects ${srcKey}]`, value);
})
.catch((reason) => {
console.error(reason);
});
}
};
```
For the lambda to be executed by the S3 resource, we need to assign it the necessary rights, similarly the lambda function will also need the rights to read and write to the S3 bucket. Here is the amplify config:
```ts
'pets-thumbnails/*': [
...
allow.resource(createImageThumbs).to(['read', 'write', 'delete']),
],
'pets/*': [
...
allow.resource(createImageThumbs).to(['read']),
],
```
The first line gives the rights w/r to the lambda in the bucket to load the files, and the second line to download the original file.
And finally here is the trigger configuration:
```ts
export const storage = defineStorage({
name: 'amplifyPetShop',
triggers: {
onUpload: defineFunction({
entry: '../functions/create-image-thumbs/handler.ts',
environment: {
TARGET_BUCKET_NAME: 'pets-thumbs',
},
}),
},
...
```

1,866,004 | Community Central - AWS Amplify | This is a submission for the The AWS Amplify Fullstack TypeScript Challenge What We... | 0 | 2024-05-27T01:01:53 | https://dev.to/kushagra102/community-central-aws-amplify-1en3 | devchallenge, awschallenge, amplify, fullstack | *This is a submission for the [The AWS Amplify Fullstack TypeScript Challenge ](https://dev.to/challenges/awschallenge)*
## What We Built
**Community Central** is a dynamic platform where users can create, view, update, and delete communities. Each community can have its own set of announcements, which are created by the community owners and are visible on the community page. The About tab provides detailed information about what the community is about, helping users understand its purpose and goals. Additionally, we have integrated **Crisp** support to ensure customer satisfaction. This project was built using **Next.js** for the frontend and **AWS Amplify Gen 2** for the backend.
## Demo and Code
* Live Deployment - https://main.d7jv2qcnifbzj.amplifyapp.com
* Source Code - https://github.com/Kushagra102/amplify-aws
## Integrations
<!-- Tell us which qualifying technologies you integrated, and how you used them. -->
* **Data -** A nested(complex) production ready CRUD.
* **Authentication -** Via Authenticator component and email verification based Auth.
* **Serverless Functions -** Used for sending Welcome Message via Email to the New Users.
* **File Storage -** Used for storing Image Files throughout the application.
## Journey
Our journey with Community Central started with setting up AWS Amplify Gen 2. Having experience with Gen 1, transitioning to Gen 2 was a seamless and exciting experience for us. The new features and improvements in Gen 2 significantly enhanced our development process.
The first major learning curve was establishing relationships in the datastore using the `hasMany` and `belongsTo` directives, which allowed us to query nested data efficiently. Mastering this was crucial for building a robust backend for our app.
Our initial success came with establishing authentication and creating a clutter-free CRUD interface for our users. Using Amplify UI components and connected forms was a thrilling experience. The way Amplify automatically generates create and update forms streamlined our development process, making it faster and more efficient.
We also brainstormed potential triggers for our app, such as sending a welcome email upon signup, notifying owners when a community is created, and sending announcements to community members. We successfully implemented the signup triggers and are planning to incorporate create and announcement triggers in the near future.
As for optimizing the UI, we considered using the TanStack Query approach but decided to leave this for future projects with Amplify. Our focus remains on delivering a smooth and user-friendly experience for our community platform.
Looking back, we're particularly proud of how we leveraged AWS Amplify's capabilities to build a functional and efficient application. Our next steps include implementing the remaining triggers and continuing to optimize and enhance our platform based on **100's** of features that we have in our mind.
## Connected Components and Feature Full
We are excited to convey that we have Incorporated both Amplify connected components and all four integrations.
**1. Amplify Connected Components and Amplify UI -**
* Use Of Connected forms for Create and Update requests.
* Use of Authenticator for Authentication.
* Use of Tabs for seamless navigation.
* Use of Account Setting Change Password for easy reseting of passwords.
* Use of Storage Image and Manager to efficiently show and upload images to S3 (Storage).
* Encorporated Connected Forms together with Tabs for creating and managing communities and announcements.
* Alert was use to notify and block non-owners to change community settings.
* Use of Search Field to incorporate seamless search of multiple communities.
* Flex, Image, Containers, View, Divider, Heading, Button, Input, Grid and Cards.
**2. Feature Full -**
We have used Connected Components and all four features: Data, Authentication, Serverless functions, and File Storage.
* **Data:** We have used DynamoDB to securely store all the information records of the communities and users. We also created complex data relationships between the tables to query and update the information efficiently.
* **Authentication:** The users are authenticated using Amplify Auth (Cognito) to access the communities. We also save information of users like preferred usernames and names. Also, the app sends a welcome email to the user on successfully registering
* **File Storage:** Banners are a major part of the communities to express themselves, we used S3 with amplify which made our task very easy to upload and query the image files.
* **Serverless:** Developing for user experience is a major key point, in our app, we enhance the user experience by Sending Welcome emails using the Serverless Lambda function attached to the trigger on the Auth Service.
