1,897,032 | LeetCode Day 15 Binary Tree Part 5 | LeetCode No. 617. Merge Two Binary Trees You are given two binary trees root1 and... | 0 | 2024-06-22T13:01:35 | https://dev.to/flame_chan_llll/leetcode-day-15-binary-tree-part-5-3hg5 | # LeetCode No. 617. Merge Two Binary Trees
You are given two binary trees root1 and root2.
Imagine that when you put one of them to cover the other, some nodes of the two trees are overlapped while the others are not. You need to merge the two trees into a new binary tree. The merge rule is that if two nodes overlap, then sum node values up as the new value of the merged node. Otherwise, the NOT null node will be used as the node of the new tree.
Return the merged tree.
Note: The merging process must start from the root nodes of both trees.
Example 1:
Input: root1 = [1,3,2,5], root2 = [2,1,3,null,4,null,7]
Output: [3,4,5,5,4,null,7]
Example 2:
Input: root1 = [1], root2 = [1,2]
Output: [2,2]
```
public TreeNode mergeTrees(TreeNode root1, TreeNode root2) {
TreeNode root = new TreeNode();
if(root1 == null && root2 == null){
return null;
}
if(root1 == null){
root = root2;
root.left = mergeTrees(null, root2.left);
root.right = mergeTrees(null, root2.right);
}
if(root2 == null){
root = root1;
root.left = mergeTrees(null, root1.left);
root.right = mergeTrees(null, root1.right);
}
if(root1!=null && root2!=null){
root.val = root1.val + root2.val;
root.left = mergeTrees(root1.left, root2.left);
root.right = mergeTrees(root1.right, root2.right);
}
return root;
}
```
But I have written some trouble useless codes as well. I will truncate them.
Here we have let the root assign to non-null root reference
# LeetCode 700. Search in a Binary Search Tree
You are given the root of a binary search tree (BST) and an integer val.
Find the node in the BST that the node's value equals val and return the subtree rooted with that node. If such a node does not exist, return null.
Example 1:
Input: root = [4,2,7,1,3], val = 2
Output: [2,1,3]
Example 2:
Input: root = [4,2,7,1,3], val = 5
Output: []
Constraints:
The number of nodes in the tree is in the range [1, 5000].
1 <= Node.val <= 107
root is a binary search tree.
1 <= val <= 107
```
public TreeNode searchBST(TreeNode root, int val) {
if(root == null || root.val == val){
return root;
}
if(root.val < val){
root = searchBST(root.right, val);
}
else{
root = searchBST(root.left,val);
}
return root;
}
```
# LeetCode 98. Validate Binary Search Tree
Given the root of a binary tree, determine if it is a valid binary search tree (BST).
A valid BST is defined as follows:
The left
subtree
of a node contains only nodes with keys less than the node's key.
The right subtree of a node contains only nodes with keys greater than the node's key.
Both the left and right subtrees must also be binary search trees.
Example 1:
Input: root = [2,1,3]
Output: true
Example 2:
Input: root = [5,1,4,null,null,3,6]
Output: false
Explanation: The root node's value is 5 but its right child's value is 4.
Constraints:
The number of nodes in the tree is in the range [1, 104].
-231 <= Node.val <= 231 - 1
## *Wrong Code*
```
public boolean isValidBST(TreeNode root) {
if(root == null){
return true;
}
return isBST(root.left,root.val, true, root.val, true) &&
isBST(root.right, root.val, false, root.val,false);
}
public boolean isBST(TreeNode cur, int formerVal, boolean isLeft, int rootVal, boolean leftToRoot){
if(cur == null){
return true;
}
boolean isLeftToRoot = (leftToRoot && cur.val < rootVal) ||
(!leftToRoot && cur.val > rootVal);
boolean isValidChild = (isLeft && cur.val < formerVal) ||
(!isLeft && cur.val > formerVal);
if(isLeftToRoot && isValidChild){
boolean leftTrue = isBST(cur.left, cur.val, true, rootVal,leftToRoot);
boolean rightTure = isBST(cur.right, cur.val, false, rootVal,leftToRoot);
return leftTrue && rightTure;
}
return false;
}
```
- 1, Add too many sub evaluation but cannot cover the full possibility
- 2, BST is a special data structure that each left child(left sub tree less than parent )
- ### so according to 2, we can get that instead of above pre-order traverse, we can use in-order traverse. left- mid - right it is increasing assignment.

1,897,009 | Build A CSS Word Search Game In ... CSS! | I've heard it so many times: CSS is not a programming language — or — why do it in CSS, when you can... | 0 | 2024-06-22T12:59:57 | https://dev.to/madsstoumann/build-a-css-word-search-game-in-css-10d1 | css, html, webdev, showdev | I've heard it **so** many times: CSS is not a programming language — or — why do it in CSS, when you can do it in JavaScript?
Why, indeed? Because I **love** CSS, and love a fun challenge!
In this tutorial, we'll be building a CSS Word Search Game in CSS:
In an [earlier article](https://dev.to/madsstoumann/getting-creative-with-css-grid-mco), I looked into creative ways you can utilize CSS grid.
The approach for the word game is similar: A 12x12 grid using `grid-area` for the words.
Let's dive in.
---
## Markup
For each word, we create a `<fieldset>`:
```html
<fieldset name="w7" class="horizontal">
<input type="checkbox" value="G">
<input type="checkbox" value="A">
<input type="checkbox" value="P">
</fieldset>
```
`name` is a unique identifier for the word, and for `class` we can use either `horizontal` or `vertical`.
---
## CSS
First, we need a wrapper with the 12x12 grid:
```css
.word-search {
aspect-ratio: 1 / 1;
container-type: inline-size;
display: grid;
font-family: system-ui, sans-serif;
font-size: 3.5cqi;
grid-template-columns: repeat(12, 1fr);
grid-template-rows: repeat(12, 1fr);
padding: 1px;
}
```
Then, we style the `<input type="checkbox">`-tags:
```css
input {
all: unset;
aspect-ratio: 1 / 1;
background: #FFF;
display: grid;
place-content: center;
user-select: none;
width: calc((100cqi / 12) - 1px);
&:checked {
background: var(--bg, #FF0);
color: var(--c, #000);
}
&::after {
content: attr(value);
}
}
```
First, we **unset** all the defaults, then set the width of each to a 12th of the total width minus the gap.
A pseudo-element with the `value` of the input is placed `::after`.
---
Now, let's add the CSS for the word we created in the markup earlier – including the "logic" of the game:
```css
[name=w7] {
grid-area: 2/ 10 / 2 / 13;
&:has(:checked + :checked + :checked) {
--bg: #FF69B4;
}
}
```
So, what's going on?
The `grid-area`-declaration places the word in the **second row**, the **tenth column**, ends at the same row and at the **13th column**, as the word is **3 characters**, so `10 + 3 = 13`.
Next, we check if all the `<input>`s in the fieldset are `:checked`. Because it's a 3-letter word, we need to check for `:checked` 3 times.
Can you guess how many `:checked` are required for 4-letter words?! 😂
Let's click on those 3 letters — the final 3 in the second row. When you click on a single letter, the background color turns yellow, but when all 3 have been clicked/checked, we get:
And that's it — now find 25 words more (or just click all the letters!). When you've found all the words, you'll have 3 slots left, with the letters A, B and C.

1,897,029 | Understanding CSS: Advantages and Disadvantages of Inline, Internal, and External Styles | Introduction What is CSS CSS, also known as cascading style sheet, is one of... | 0 | 2024-06-22T12:56:48 | https://dev.to/brendan_frasser/understanding-css-advantages-and-disadvantages-of-inline-internal-and-external-styles-glk |
## Introduction
### What is CSS
- CSS, also known as cascading style sheet, is one of the core technologies of the web.
- CSS is used to describe the visual style and presentation of the page. It consists of countless properties that developers can use to format (edit) the content of a web page.
You can write CSS in three places: inline CSS, internal CSS, and external CSS. Today, we'll look at their advantages and disadvantages.
## Inline CSS
Inline CSS applies CSS styles directly into the HTML code using the style attribute. For example:
``` HTML
<p style="color: blue; font-size: 14px;">This is a styled paragraph.</p>
```
### Advantages of Inline CSS
- An advantage of using inline CSS is the ease with which you can style a particular web page component, or, in other words, specificity. This ability to change the styling of any specific element ties into its next advantage.
- Inline CSS makes testing a style or changing a particular style on a webpage effortless.
- One of the most significant advantages of inline CSS is that it doesn't require external files or links. This advantage means you can streamline the development process as all the code is within the HTML code. This feature makes it very useful when working on small projects.
### Disadvantages of Inline CSS
- A significant disadvantage of using inline CSS is managing the code as a project gets bigger and bigger. With different styles scattered throughout the HTML, editing the webpage or making global changes becomes more complicated and bug-prone because each element that needs a style change/update must be searched for and changed manually.
- Another disadvantage is increased repetition when multiple elements in the HTML need the same styling. Since developers have to style each component manually, they repeat the same CSS code, making the code large and complex to read, increasing the likelihood of bugs.
## Internal CSS
Internal CSS is a way of applying CSS to a webpage that involves using a style tag in the head section of the HTML file. For example:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Internal CSS Example</title>
<style>
body {
font-family: Arial, sans-serif;
}
h1 {
color: blue;
}
p {
font-size: 14px;
}
</style>
</head>
<body>
<h1>Welcome to My Website</h1>
<p>This is an example of internal CSS.</p>
</body>
</html>
```
This method allows you to edit and modify the style and feel of the page without needing an external file for the CSS.
### Advantages of Internal CSS
- When using internal CSS, the styles are confined to the specific page, which helps avoid conflicts with styles on other pages. This approach guarantees that the CSS rules defined within the style tag in the head section apply only to that document. As a result, developers can specify the styling of individual pages without worrying about unintended side effects on other parts of the website, making internal CSS a convenient choice for page-specific customizations.
- Another advantage of internal CSS that ties into the previous one is it provides greater control and customization of the individual pages of a website.
- Another advantage of internal CSS is that it can contribute to faster page loading times, as no additional HTTP requests are needed to fetch an external stylesheet.
### Disadvantages of Inline CSS
- A significant disadvantage of internal CSS is the duplication of styles across multiple HTML files. Each HTML file must have a separate style section with the same CSS code when different pages need the same style. This repetition not only increases the overall size of the website but also complicates maintenance since any changes to the styles must be done manually in every file. This disadvantage can lead to inconsistencies and a higher chance of errors, making internal CSS less efficient for larger websites that require uniform styling across multiple pages.
- Another notable disadvantage of internal CSS is the increased HTML file size. Adding styles directly within the style tag in each HTML document's head section increases the overall file size, especially if there are large or complex styles. This disadvantage can lead to longer load times for users with slower internet connections.
## External CSS
External CSS involves styling in a separate .css file and linking it to an HTML document using the link tag in the head section. This way of writing CSS promotes the reusability of styles and better organization across multiple pages. An example of what your HTML code will look like is:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>External CSS Example</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<h1>Welcome to My Website</h1>
<p>This is an example of external CSS.</p>
</body>
</html>
```
``` css
An example of the CSS is :
body {
font-family: Arial, sans-serif;
}
h1 {
color: blue;
}
p {
font-size: 14px;
}
```
### Advantages of external CSS
- A significant advantage of external CSS is its reusability, as a single stylesheet can be linked across multiple web pages, significantly reducing repetition and redundancy. This means that common styles only need to be defined once in an external .css file, which you can then link to any number of HTML documents. This advantage makes development more streamlined and makes things like site-wide updates much more straightforward and efficient.
- A vital performance advantage of external CSS is that it uses browser caching to improve loading times after the initial visit. When a user first visits a website, the external stylesheet is downloaded and stored in the browser cache. On subsequent visits, the browser can quickly retrieve the cached CSS file rather than downloading it again, significantly reducing load times.
### Disadvantages of Inline CSS
- A disadvantage of external CSS is its reliance on additional HTTP requests to load the stylesheet. Each time a web page is accessed, the browser must fetch the external CSS file, which can cause a delay, especially on slower networks or if the server hosting the stylesheet is under heavy load. The webpage may render without styles if the CSS file fails to load due to network issues or server errors.
## Choosing The Right Approach
There are multiple factors to consider when considering what CSS type to use when working on a project, as there is no one-size-fits-all way of looking at it. Some of these factors are
- Project Size:
More extensive projects benefit from external CSS for better management and scalability.
- Complexity:
Complex designs are easier to handle with external CSS due to all the styling taking place in one place.
- Performance Needs:
Inline and internal CSS can be quicker for small, simple pages, while external CSS leverages caching for repeated visits.
The appropriate type of CSS depends on the project's size and specific needs. For small web pages, inline or internal CSS is enough. External CSS, however, is best for large, multi-page websites. | brendan_frasser | |
1,897,028 | Understanding DevOps: Principles, Practices, and Culture - Day 3 Recap | The Three Principles of DevOps At the heart of DevOps are three guiding principles known... | 0 | 2024-06-22T12:55:37 | https://dev.to/dilshavijay/understanding-devops-principles-practices-and-culture-day-3-recap-8la | devops, beginners, challenge, practices |

1,897,022 | Basic CICD with GitHub Action | Prerequisites Virtual Machine with Public IP Docker, Docker Compose installed ... | 0 | 2024-06-22T12:47:24 | https://dev.to/tinhtq97/basic-cicd-with-github-action-3pc8 | ## Prerequisites
- Virtual Machine with Public IP
- Docker, Docker Compose installed
## Diagram
When the developer pushes a commit to the repository, GitHub Action (GA) triggers the pipeline that builds the docker image and pushes it to GitHub Container Registry (ghcr.io). Then, the next job is to connect to the server by SSH, pull the latest Docker image, and restart Docker Compose.
## Walkthrough
**Step 1**: Create a docker-compose file
```yaml
services:
web:
image: ghcr.io/yourusername/your-web-app:latest
ports:
- "8080:8080"
environment:
- DATABASE_HOST=db
- DATABASE_PORT=5432
depends_on:
- db
db:
image: ghcr.io/yourusername/your-database:latest
ports:
- "5432:5432"
environment:
- POSTGRES_DB=mydatabase
- POSTGRES_USER=myuser
- POSTGRES_PASSWORD=mypassword
volumes:
- db-data:/var/lib/postgresql/data
volumes:
db-data:
```
Create a directory that contains the docker-compose file. Save it as DIRECTORY variable.
**Step 2**: Create Repository Secrets
Go to Settings → Secrets and variables → Repository secrets → New repository secret.
**Step 3**: Create a Github Workflow
Create `.github/workflows/deploy.yaml` file
```yaml
name: Deploy to VPS
on:
push:
branches:
- main
jobs:
build:
runs-on: ubuntu-latest
permissions:
contents: read
packages: write
steps:
- name: Checkout
uses: actions/checkout@v4
- name: Set up QEMU
uses: docker/setup-qemu-action@v3
- name: Set up Docker Buildx
uses: docker/setup-buildx-action@v3
- name: Login to GitHub Container Registry
uses: docker/login-action@v3
with:
registry: ghcr.io
username: ${{ github.repository_owner }}
password: ${{ secrets.GITHUB_TOKEN }}
- name: Set SHA-COMMIT
id: vars
run: echo "sha_short=$(git rev-parse --short HEAD)" >> $GITHUB_OUTPUT
- name: Build and push image
uses: docker/build-push-action@v5
with:
context: .
platforms: linux/amd64
push: true
tags: |
ghcr.io/yourusername/your-web-app:latest
ghcr.io/yourusername/your-web-app:${{ steps.vars.outputs.sha_short }
deploy:
needs: build
runs-on: ubuntu-latest
timeout-minutes: 5
steps:
- name: Deploy
uses: appleboy/ssh-action@v1.0.3
with:
host: ${{ secrets.EC2_HOST }}

1,896,928 | Frontend Interview Preparation Day 1 - The Plan | Hello everyone 🙏, just writing this post to motivate you all to start preparation of you dream... | 0 | 2024-06-22T12:46:03 | https://dev.to/nishantsinghchandel/maang-interview-preparation-day-1-the-plan-3i61 | javascript, interview, webdev, career | Hello everyone :pray:, just writing this post to motivate you all to start preparation of you dream company MAANG. This is just a post related to what I am planning to do in coming weeks and I will try to post each and everything related to interview preparation.
**20 June 2024,** is the last working :man_technologist: day at **MakeMyTrip**. As I am looking forward for better opportunity and career. So, I took this decision because I need a break from work, meanwhile I will also learn DSA and other stuff.
---
Making it short, today **21 June 2024**, I started to plan :bookmark: everything how much time I have to study, how many topics I have to cover etc. I will go one by one.
1. I generate a master plan using **chat-gpt** of 8 weeks of interview preparation. I will suggest you all to do the same. This plan covers an 8-week period, focusing on algorithms, data structures, system design, and behavioral questions. Each day has a study duration of approximately 4-5 hours.
- **Daily Tasks**: :pie:
- **June 21 (Fri)**: Introduction to arrays and strings, practice easy problems. (4 hours) - DONE
- **June 22 (Sat)**: Study linked lists, practice easy problems. (4 hours)
- **June 23 (Sun)**: Dive into stacks and queues, practice medium problems. (4 hours)
- **June 24 (Mon)**: Understand hash tables, practice medium problems. (4 hours)
- **June 25 (Tue)**: Learn trees (binary trees and binary search trees), practice easy problems. (4 hours)
- **June 26 (Wed)**: Explore graphs, practice easy problems. (4 hours)
- **June 27 (Thu)**: Review and recap the week’s topics, practice a mixed set of problems. (4 hours)
- **June 28 (Fri)**: Study heaps and priority queues, practice medium problems. (4 hours)
- **June 29 (Sat)**: Understand tries, practice medium problems. (4 hours)
- **June 30 (Sun)**: Learn about sorting algorithms, practice medium problems. (4 hours)
- **July 1 (Mon)**: Explore searching algorithms, practice medium problems. (4 hours)
- **July 2 (Tue)**: Study dynamic programming, practice medium problems. (4 hours)
- **July 3 (Wed)**: Introduction to backtracking, practice medium problems. (4 hours)
- **July 4 (Thu)**: Review and recap the week’s topics, practice a mixed set of problems. (4 hours)
_This is my plan don't try the same if you are working professional with other priorities. Please take help from Chat-GPT to generate customized plan, it is free._
2. Next, I updated my resume :spiral_notepad:, If you have any confusion :confused: about how to make a resume, here is the link please follow along, it is very helpful.
[Design, write, and format a professional resume that stands out](https://applieddigitalskills.withgoogle.com/c/middle-and-high-school/en/create-a-resume-in-google-docs/overview.html)
- :white_check_mark: Resume should be of 1 page :page_facing_up: only, which has all the skills you know and which is required for job. Don't mention anything you don't know.
- :white_check_mark: Resume should contain your experiences with impact, like if you developed something and it reduces cost mention it properly.
- :white_check_mark: Focus on Relevance: Highlight experiences that are most relevant to the job you are applying for.
- :white_check_mark: Use Action Verbs: Start each bullet point with strong action verbs like "developed," "managed," "implemented," etc.
- :white_check_mark: Quantify Achievements: Whenever possible, use numbers to quantify your achievements (e.g., "Increased sales by 20%").
- :white_check_mark: Be Specific: Provide specific examples of your accomplishments and responsibilities.
- :white_check_mark: Highlight Key Skills: Emphasize skills that are listed in the job description.
3. I bought some stuffs from amazon which helps in problem solving. Don't get excited it's just a small white board :clipboard:. I prefer this board because it's portable and handy, for large white boards you have to hang it some where or you need extra space during coding. So, I highly recommend to buy this size of white board. It easily fits your desk.
(White Board)[https://amzn.in/d/098jHWGO]
4. A timer for deep focus :bulb:, so that you can keep track that you are working not wasting time. I pause the timer if I leave my seat. Just a website which helps you to keep track of it.
[Timer](https://www.timeanddate.com/timer/)
5. Notebook :notebook_with_decorative_cover: to write important points which you need before interview for faster revision.
6. Of course a laptop :computer: for coding.
_That's all, you are almost ready with your plan for this battle. This planning is almost took 2 hours_
**Now the execution time ** :alarm_clock:
**June 21 (Fri)**: Introduction to arrays and strings, practice easy problems. (4 hours)
So, on day 1 after planning everything I watch some lectures from my Udemy courses on Array & Strings from this course, this is for javascript developers, if you are looking for DSA in other language feel free to search on Udemy or other platform. This course cost me only INR 499 :moneybag:.

1,897,020 | Data Science in E-commerce: Optimizing the Customer Journey with Every Click | The online shopping environment remains extremely saturated and firms are always on the lookout for... | 0 | 2024-06-22T12:44:55 | https://dev.to/fizza_c3e734ee2a307cf35e5/data-science-in-e-commerce-optimizing-the-customer-journey-with-every-click-3pkg | datascience, python, ai | The online shopping environment remains extremely saturated and firms are always on the lookout for the best strategy on how they can differentiate themselves. With the rise in the availability of data, interpreting the customers and achieving a competitive edge is more often than not based on the knowledge that is gained. This is where data science comes in, providing a whole suite of tools to help businesses and organizations make each interaction feel distinctive and, more importantly, advantageous.
_From Frustration to Frictionless:_ In this paper, the various ways through which Data Science helps to clear the way are examined.
Suppose a customer shops in your store either online or perhaps at a physical store. This may mean that the client is entangled in an avalanche of choices, with no clear requirements, or the specific product they are in need of. Using data science, what was previously an aggravating process can instead become a pleasant ride. Here's how:
_• Recommendation Systems:_ Through an understanding of customers’ past purchase history, website visits, and a search done on the internet, data science enables recommendation systems to get close to recommending products that the customer is likely to buy. Not only does it aid in identifying products they may be interested in but it also serves to sell more.
_• Personalized Search:_ The use of algorithms in data science can help to narrow down the results and focus them on the needs of each user. This suggests that, for instance, a customer searching ‘running shoe’ might only be presented with the foot type, brand, or activity level they are interested in.
_Business intelligence enables you to increase your prices through factors such as your competitor’s prices, the demand for your product or service, and how much your clients are willing to spend. This way you can be sure you are operating in the most efficient and competitive manner possible and you gain the maximum possible profits.
_• A/B Testing:_ Data Science also enables this process of Centering website elements, it may be the positions of products, the buttons *Buy Now* or *Learn More*, or even the textual content of the website. This way, if you see which of the versions gets the highest response from the customers, then you can easily determine which design is best for increasing the conversion rates.
_• Sentiment Analysis:_ Text mining is also used here, there, and everywhere, but customer reviews, social media comments, and support tickets can reveal the overall customer sentiment. This can enable you to respond to complaints effectively and also modify your products and services in order to better suit the needs of your patrons and establish better rapport with them.
**The Power of Python: Finding the Fuel for Your E-commerce Data Science Path**
Python is one of the most popular languages with many applications, including data science owing to its excellent features such as readability, availability of rich packages, and a large community. So in the case where you are interested in applying this exciting field and using the power of Big Data in e-commerce, there are countless courses available online that can help kick-start you in this direction. Some of the key areas to look into when selecting the right [Python course for data science](https://bostoninstituteofanalytics.org/data-science-and-artificial-intelligence/) to take with regard to data science are the learning modality, the cost of the course, and the existing practical experience.
Applying data science to e-commerce businesses has numerous opportunities to help, and establish a competitive advantage. Whether it is about developing a targeted advertising strategy, improving the customer experience, designing better product assortments, or setting appropriate prices and managing inventory, the proactive use of data science bears an untold potential to improve a range of business objectives fundamentally tied to happier customers, increased individual and overall share-of-wallet, and sustainable growth.

_Computer Science , solving tomorrow’s problem with yesterday's bugs!_ Computer Science deals with the study of algorithms that define logic, data structures, computation, and databases. It creates a website and makes analytical algorithms to find trends of providing both theoretical and practical tools for user-friendly systems.
It is obviously understood that data and databases are among the core thoughts within the realm of computer science, accommodate, organize, and analyze data in its diversified forms and structures. RDBMS/SQL, NoSQL, cloud, and time series databases scale and flex to bridge that gap.
Information analysis and visualization are interpreted into meaningful actions that result from the application of visualization software, machine learning algorithms, and data mining techniques. It is powered and made more powerful by next-generation big data technologies like Hadoop and Spark.
**Connecting the Dots: How Databases Fuel Data Science Innovations!!**
Lets us understand with an example : fictional online-retail - **‘ShopMart’**
In this example of online retail 'ShopMart':
- The Role of computer science ensures creating secure, scalable, and user-friendly systems.
- Database structure, design, and normalization ensure a secure system while maintaining data storage and organizing on types of data. Transaction management guarantees reliable operations and integrity of data even in case of system failure.
- Sales data analysis depicts trends and facilitates better purchase experiences.It aids in the optimization of purchase experiences by identifying the trends and recommending relevant merchandise.
Descriptive statistics algorithms, collaborative filtering tools like Tensorflow, Seaborn, together with data mining and big data technologies: Hadoop and Spark used.
Thus Computer Science Driving insights and innovation through data.

1,896,484 | Developing for Scale and Quality with AI - Micro-Models | Written by Eletroswing Introduction Certainly, AI-based technologies are here to stay and... | 0 | 2024-06-22T12:41:22 | https://dev.to/eletroswing/developing-for-scale-and-quality-with-ai-micro-models-4i8n | ai, chatgpt, openai, opensource | _Written by Eletroswing_
# Introduction
Certainly, AI-based technologies are here to stay and represent our most imminent technological boom. Much of this is due to OpenAI's launch of its LLM (large language model), ChatGPT. This advancement has motivated the creation of thousands of new services in an industry that, just months before its release, was considered unfeasible. However, this progress comes with a price, one that could be costly in the long run.
# Dependence on Large Models
With the emergence of OpenAI and its API, many companies have been built exclusively around these technologies. Many researchers in the field still adhere to the premise of keeping everything in a single large model, despite the daily launch of thousands of new technologies, models being trained, and datasets being created.
# Challenges of Training Large Models
When faced with a task, the common approach is to train a single specific model, such as "using the OpenAI API". But why spend so many resources on something that might not be as satisfactory as expected? Consider an example: an eye movement substitution model.
# Example of an Eye Movement Substitution Model
If you try to develop this by training a model from scratch, you quickly realize the complexity. Your model needs to identify, track, generate, and substitute the eye in videos. Look at how much work goes into a single objective.
Additionally, suppose your model takes 4 minutes per video. How would you scale this? Your only solution would be hardware, which is expensive and unfeasible.
# Micro-Models
This brings us to the concept of micro-models.
## Concept of Micro-Models
What if, instead of generalizing everything into a single model, we broke it into stages and utilized existing specialist models? This way, we create a modular and scalable pipeline by adding models and code between them. We could have a queue for identifying, another for tracking, another for generating, and another for substituting.
By preparing between the stages with code, and since the models are already specialists in their respective subjects, we can easily reduce inference time. We can also run parts in parallel if necessary. If tracking is fast but generation is not, we can simply add another consumer to the queue to handle the load.
Transformation with Micro-Models
Basically, we transform this:
Into this:
# Benefits of Micro-Models
With this approach, despite seeming more complex, we achieve greater scalability and efficiency in our system. Additionally, we improve integration efficiency and speed, as we can modify only specific parts of the system instead of having to regenerate a model or perform fine-tuning, right?
# Conclusion
Adopting micro-models allows for the creation of more scalable and efficient systems, making the most of existing resources and facilitating the continuous maintenance and evolution of AI-based solutions. | eletroswing |
1,897,016 | Telnet multiple hosts with telnetlib3 | Why did I create this script? When you set up the new environment, you need to check... | 0 | 2024-06-22T12:38:43 | https://dev.to/tinhtq97/telnet-multiple-hosts-with-telnetlib3-55bi | ## Why did I create this script?
When you set up the new environment, you need to check whether all hosts and ports are reachable or not but you don’t want to execute telnet host port multiple times. It is a boring step that sometimes you may make a mistake here so I need to create a script to telnet multiple hosts with telnetlib3 library.
(telnetlib will be deprecated in the new version)
## Requirements
Python > 3.7
## Setup
**Step 1**: Install telnetlib3
```bash
pip install telnetlib3
```
**Step 2**: Create a `main.py` file
```python
import asyncio
import telnetlib3
import io
async def telnet_welcome_message(telnet_host, telnet_port):
telnet_connection = True
try:
await asyncio.wait_for(telnetlib3.open_connection(telnet_host, telnet_port), 5)
except (asyncio.exceptions.TimeoutError, OSError) as e:
telnet_connection = False
print(e)
return telnet_connection
failed_connection = []
with open("server.txt", "r") as file:
lines = file.readlines()
for line in lines:
info = line.split(",")
host = info[0]
port = int(info[1])
connection = asyncio.run(telnet_welcome_message(host, port))
if not connection:
failed_connection.append({"host": host, "port": port})
print(failed_connection)
```
This script states that the hosts and ports are reachable for 5 minutes, if a timeout or denied, it returns the failed connections.
**Step 3**: Create a server.txt file that contains the host and port like this
```text
192.168.1.1,8080
192.168.10.1,8191
```
**Step 4**: Execute the below command to see which IP and port are not reached
```bash
python main.py
```

1,896,840 | Enhance PhpStorm File Templates with Velocity 🧪 | Using PhpStorm’s File Templates makes it easier to create linked files in frameworks like... | 0 | 2024-06-22T12:24:38 | https://dev.to/chemix/enhance-phpstorm-file-templates-with-velocity-4n1g | phpstorm, templates, howto, nettefw | Using PhpStorm’s File Templates makes it easier to create linked files in frameworks like presenters/controlers and their templates. By setting up custom templates, you can quickly generate these files with the right structure. Using Velocity variables like `${NAME}` and `${DIR_PATH}` can helps automatically create file names and paths, reducing mistakes.
## 🜁
In my case, I use the [Nette Framework](https://www.nette.org). There is a Presenter (HomepagePresenter.php) connected with a Template (Homepage.default.latte) in a Module (Admin):
```
/app/modules/Admin/Homepage/templates/Homepage.default
/app/modules/Admin/Homepage/HomepagePresenter.php
```
I want a File Template that asks for just one name and prepares everything else 💥
1. Go to: Settings → Editor → File and Code Templates
2. Create a new Template and use the variable `${NAME}`
## 🜛
_use variables in both the code and the path_
For the second file, use “Create Child Template File”🜔
We can create another variable named `${MODULE}` for setting the namespace like this:
```
namespace App\\${MODULE}Module\Presenters;
```
But ...
## 🜇 / 🜂 = 🜸 + 🜍🜞
when you study a little bit of [Velocity templates](https://velocity.apache.org/engine/devel/user-guide.html) and the variables that [PhpStorm provides](https://www.jetbrains.com/help/idea/file-template-variables.html#predefined_template_variables), you can combine them to automate some processes.
In Velocity, `#set` is used for variable settings, and PhpStorm suggests the variable `${DIR_PATH}` – the path to the directory of the new file (relative to the project root).
So we can start our Presenter template with this power 🜣 and use new variable `${moduleName}` in the code.
```
#set($dirPath = ${DIR_PATH})
#set($parentDirPath = $dirPath.substring(0, $dirPath.lastIndexOf("/")))
#set($moduleName = $parentDirPath.substring($parentDirPath.lastIndexOf("/") + 1))
<?php
namespace App\\${moduleName}Module\Presenters;
```
And that’s it. Just a few lines of Velocity and more automated creation of File Templates is done. There is no magic, just digital alchemy 👨🔬⚗️ | chemix |
1,896,925 | Why Asking 'Which Programming Language is Good or Bad?' is the Wrong Question | Hello fellow developers and code newbies. My name is Amir Bekhit aka Bek Brace, and the following is... | 0 | 2024-06-22T12:23:24 | https://dev.to/bekbrace/why-asking-which-programming-language-is-good-or-bad-is-the-wrong-question-2kpc | productivity, programming, watercooler, newbie | Hello fellow developers and code newbies.
My name is Amir Bekhit aka Bek Brace, and the following is my honest opinion about what I think of the most famous question on twitter ...
_**Why Asking "Which Programming Language is Good or Bad?" is the Wrong Question**_
As developers, we often find ourselves in debates about which programming language is the best. But let’s be honest, asking "Which programming language is good and which is bad?" isn’t really helpful. Here’s why this question might be leading us astray and what we should focus on instead.
# The Problem with "Good" and "Bad"
Labeling programming languages as “good” or “bad” oversimplifies a complex topic.
> >>> But I love Python! It's the best for everything, for automation, ML, DS, game dev, web dev, coffee making, and steak grilling ... "
, a drunk friend said
Each language has its strengths and weaknesses, and what works for one project might be a poor choice for another.
{% youtube nqID_K6G-zc %}
_**Here are a few points to consider:**_
- Context Matters: The right tool for the job depends on what you’re trying to achieve.
Are you building a web app, a mobile app, a game, or a data analysis tool? Each domain has languages that are more suited to it.
- Personal Preference: What’s good for one developer might be frustrating for another. Some people love Python for its readability, while others swear by the performance of C++.
- Community and Ecosystem: The support and libraries available for a language can make a big difference. A “bad” language with a strong community and ecosystem can be more productive than a “good” language that’s less supported.
_Choosing the Right Language for Your Project_
**Instead of asking which language is good or bad, ask yourself these questions:
**
# What is the Project Scope?
For quick scripts or automation tasks, Python might be the way to go.
For high-performance applications, consider C++ or Rust.
# What is Your Team’s Expertise?
If your team is experienced in JavaScript, building a web app with Node.js or React makes sense.
If you’re all Java experts, leveraging Spring for backend services can speed up development.
# What are the Project Requirements?
Need real-time performance? Languages like C++ or Rust could be beneficial.
Building a web frontend? JavaScript (or TypeScript) is almost unavoidable.
# What Ecosystem and Libraries are Available?
Does the language have the libraries you need?
Is there a strong community for support and contributions?
Embracing a Growth Mindset
Instead of sticking to what we know and debating which language is better, let's embrace learning.
Each language can teach us something new and expand our thinking as developers. Here’s how:
**Learn Multiple Languages:** Understanding the basics of different languages can give you more tools to solve problems.
**Focus on Concepts:** Many programming concepts are universal. Learning them in one language can often transfer to others.
**Stay Curious:** The tech landscape is always evolving. Staying curious and open-minded can keep you ahead of the curve.
Conclusion
In the end, no programming language is universally good or bad, and as I said in the video, it's a vehicle that will take you where you want. It’s all about finding the right tool for the job and continuously learning.
By focusing on what languages can offer in specific contexts, we can make more informed decisions and become better developers.
So next time someone asks you, “Which programming language is the best?” tell them -> Amir said: "for which purpose?" then consider diving into a discussion about their project needs instead. It’s a more productive and insightful conversation.
Thank you for reading, hope this was useful, and I will catch you in the next one. | bekbrace |

The thumbnail perfectly describes reason why meditation is crucial in our day in age.
With the rapid advancements in AI and technology, thinking for ourselves can feel impossible as we are constantly bombarded with information and distractions. This is where meditation becomes crucial.
I found myself in need of a mental reset.
## The Importance of Meditation Today
As a developer and someone who works behind the screen more then 8h a day(95% of people here do I pressume) Meditation offered a quick, effecive reset and clarity(even euphoria if done consistently).
**Stress reduction**: In an 8-week study, a meditation style called "mindfulness meditation" reduced the inflammation response caused by stress
**Controls anxiety**: Meditation can reduce stress levels, which translates to less anxiety as well help control job-releated anxiety(something needed in our day and age). FYI almost everyone now suffers from ADHD and it's not out of nowhere.
**Enhances self-awareness**: Can help you develop a stronger understanding of yourself with how it is currently heading it is mitigated strongly.
**Lengthens attention span**: Focused-attention meditation is like weight lifting for your attention span. It helps increase the strength and endurance of your attention.
Many more advantages but I will not get further into it for but more of can find here.
> To put it shortly connecting with yourself and not being influenced by external factors has been harder then ever and may link to depresion and anxiety. With regular meditation may it be 10 min can give a high level of euphoria and mindfullness.
## How to Meditate
It's not an overall cure but it can provide the mental space needed to listen to your inner self and resist external pressures. It's easy getting "roped in" by external factors(like raise your exepctations to unresonable amounts based on Instagram stories or YouTube or some course that sells you high success rate of completion).
---
Taking time off for yourself will lead to greater productivity. Same as going to gym for physical health that will increase your mood and make you tackle professional chalanges at work etc so will having mental clarity and being mindfull. Appart from the obvious of getting into it 🧘♂️👇
- **Take a Seat**: Find a comfortable place to sit.
- **Set a Time Limit**: Start with just 10 minutes.
- **Notice Your Body**: Make sure you're comfortable and stable.
- **Feel Your Breath**: Focus on your breathing.
- **Notice When Your Mind Wanders**: It's natural for your mind to wander. Simply bring it back to your breath.
- **Be Kind to Your Wandering Mind**: Don't judge yourself for getting distracted.
- **Close with Kindness**: End your session with a moment of gratitude or kindness.
As a begginer guided meditation is what I would strongly recomend on **YouTube** bellow I added my favorite guide.
https://www.youtube.com/watch?v=GQ2blO8yATY
Consistency is key so no reason to be hard on yourself if it wont go smoothly initially or you wonder off.
---
In the fast-paced world of IT, it's easy to feel overwhelmed and suffer from issues like ADHD and impatience.
Without clarity and self control it's difficult to continuously make good decisions without emotions taking over AI worsens it even if technology is superb.
Taking time for yourself through meditation can lead to greater productivity and a more balanced life. Give it a try and see the difference it can make.

Simplified Registration Process
Registering on Apocalypse Dark Web Market is a breeze. With just a username, password, and a simple captcha challenge, your account is quickly set up. Remember to save the provided mnemonic code, ensuring access to your account in case you forget your password.
Strict Market Rules
Apocalypse Dark Web Market adheres to industry norms regarding prohibited sales. Activities such as weapons trade, child pornography, and terrorism-related ventures are strictly forbidden. Furthermore, engaging in off-market deals is not allowed. New vendors are required to post a $250 bond, a reasonable fee for a market of this size. Notably, vendor refugees from other markets are also welcomed, with the opportunity to receive a free bond.
Efficient Product Search
Searching for products is made easy on Apocalypse Dark Web Market. You can either navigate through the listed categories or utilize the search bar at the top of the page. However, the lack of advanced search options prevents filtering by shipping origin or sorting search results.

Monitoring pending orders can be done within your user dashboard, granting the ability to receive orders, leave reviews, or raise disputes. Remember, it is advisable to message vendors first before initiating any disputes within the 12-day escrow window, as most vendors are willing to resolve issues amicably.

Apocalypse Dark Web Market excels in offering a simple and user-friendly interface, allowing for swift navigation. A wide range of product types is available, catering to diverse needs.

#### Step 3: Create Packages
1. **Navigate to the `src/main/java` directory** in your project explorer.
2. **Create new packages** by right-clicking on the `java` directory, selecting `New Folder`, and naming it according to your package structure (e.g., `com/example/myproject`).
#### Step 4: Add Classes to Your Package
1. **Right-click on the package** you just created (e.g., `com/example/myproject`) and select `New File`.
2. **Name the file** (e.g., `MyClass.java`) and press Enter.
3. **Define your class** within this file. For example:
```java
package com.example.myproject;
public class MyClass {
public static void main(String[] args) {
System.out.println("Hello, Spring Boot!");
}
}
```
#### Step 5: Configure Spring Boot
Ensure you have a main application class to run your Spring Boot application. It should be in the root package or a subpackage of it.
Example `Application.java` in the root package `com.example.myproject`:
```java
package com.example.myproject;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
```
#### Step 6: Run Your Spring Boot Application
1. **Open the integrated terminal** in VS Code by pressing `Ctrl + ` (backtick).
2. **Navigate to the project directory** if not already there.
3. **Use Maven to run your application**:
```sh
mvn spring-boot:run
```
Alternatively, you can build your project and run the jar file:
```sh
mvn package
java -jar target/myproject-0.0.1-SNAPSHOT.jar
```
### Summary
By following these steps, you can create a package structure in your Spring Boot project using VS Code, add classes, configure your application, and run it successfully. This setup allows you to organize your project code logically and maintainably.

1,896,922 | Pass by Mystery: Unraveling Value Changes in Go | In Golang, data falls into two main categories: Value Types: These are independent data... | 0 | 2024-06-22T11:30:27 | https://dev.to/go-dev-001/pass-by-mystery-unraveling-value-changes-in-go-3o2p | go | ## In Golang, data falls into two main categories:
> **Value Types:** These are independent data units that are copied when passed around. Examples include:
_Basic types:_ integers (int, uint, etc.), floating-point numbers (float32, float64), booleans (bool), strings, runes (single characters).
_Arrays:_ Fixed-size collections of the same type (e.g., [5]int). Changes to array elements within functions create copies, not modifying the original array.
> **Reference Types:** These hold a reference (memory address) to the actual data, allowing functions to modify the original data. Examples include:
_Slices:_ Dynamically sized, resizable views into underlying arrays. Changes to slice elements within functions directly modify the original data.
_Maps:_ Unordered collections of key-value pairs. Changes to map values within functions modify the original map.
Pointers: Variables that store memory addresses of other variables, allowing indirect access and manipulation.
## **Here is a sample program to showcase these properties:**
```
package main
import "fmt"
func main() {
// Declare and initialize variables
fmt.Println("-------original------") // Print a header for initial values
// Array - Fixed size collection of elements of the same type
var arr [2]int // Declare an array of size 2 to hold integers
arr[0] = 1 // Initialize the first element with value 1
arr[1] = 2 // Initialize the second element with value 2
// Slice - Dynamically sized view into an underlying array
slice := []int{1, 2} // Create a slice with initial values 1 and 2
// Map - Unordered collection of key-value pairs
m := map[int]int{1: 1, 2: 2} // Create a map with key-value pairs (1:1, 2:2)
// Print the initial state of array, slice, and map
fmt.Printf("array = %v, slice = %v, map = %v\n", arr, slice, m)
// Call function f to potentially modify the passed variables
f(arr, slice, m) // Pass the array (copy), slice (reference), and map (reference)
fmt.Println() // Print an empty line for separation
fmt.Println("-------post update------") // Print a header for modified values
// Print the state of array, slice, and map after function calls
fmt.Printf("array = %v, slice = %v, map = %v\n", arr, slice, m)
}
// Function f takes array, slice, and map (references)
func f(arr [2]int, slice []int, m map[int]int) {
// Modify elements within the array (array is passed by value, changes won't affect original)
arr[0] = 2 // Change the first element of the array copy to 2
// Modify elements within the slice (slice is passed by reference, changes will affect original)
slice[0] = 2 // Change the first element of the slice to 2
// Modify elements within the map (map is passed by reference, changes will affect original)
m[1] = 2 // Change the value associated with key 1 in the map to 2
// Call function f2 to potentially modify the passed variables further
f2(arr, slice, m)
}
// Function f2 takes array, slice, and map (references)
func f2(arr [2]int, slice []int, m map[int]int) {
// Modify elements within the array (array is passed by value, changes won't affect original)
arr[1] = 3 // Change the second element of the array copy to 3
// Modify elements within the slice (slice is passed by reference, changes will affect original)
slice[1] = 3 // Change the second element of the slice to 3
// Modify elements within the map (map is passed by reference, changes will affect original)
m[2] = 3 // Change the value associated with key 2 (or create a new key-value pair) in the map to 3
}
```
## **Output**
```
-------original------
array = [1 2], slice = [1 2], map = map[1:1 2:2]
-------post update------
array = [1 2], slice = [2 3], map = map[1:2 2:3]
```

1,895,746 | Level Up Your Customer Support With Telinga API, Twilio APIs & Gemini AI | This is a submission for Twilio Challenge v24.06.12 What I Built In today's... | 0 | 2024-06-22T11:39:39 | https://dev.to/onwuagba/level-up-your-customer-support-with-telinga-api-twilio-apis-gemini-ai-3kfc | devchallenge, twiliochallenge, ai, twilio | *This is a submission for [Twilio Challenge v24.06.12](https://dev.to/challenges/twilio)*
## What I Built
In today's experience-driven business landscape, exceptional customer support is no longer a luxury, it's a necessity. But managing a constant flow of feedback, analyzing sentiment, and crafting personalized responses can be a time-consuming and resource-intensive challenge.
Enter **Telinga**, a **customer support API** built with Django, Twilio, and Gemini AI. Telinga streamlines the process, automates tasks, and empowers you to deliver an exceptional customer experience that keeps your customers happy and coming back for more. Telinga seamlessly captures customers feedback through the Twilio API, which integrates with various communication channels like SMS and email. But Telinga goes beyond just collecting messages. It leverages the power of Gemini AI to analyze the sentiment of the feedback. Is it positive praise? A neutral inquiry? Or a negative outburst requiring immediate attention? Telinga intelligently categorizes the sentiment, allowing you to prioritize responses and address critical issues promptly.
## Demo
### How Telinga Works:
1) **Onbaording**: Business Aggregators register and obtain API Key used in making subsequent calls
2) **Upload Customer Data**: Integrators hit the Telinga API with a csv file containing the customer data using the template in the attached collection. This file is uploaded alongside the message template and delivery time (now or time in GMT)
3) **Notification**: Telinga will automatically send an SMS or email notification based on the information you provide. Notifications can be sent immediately (delivery_time set to "now") or scheduled for a specific time.
4) **Feedback Collection**: Customer feedback is collected via SMS or email.
5) **Language Detection and Translation**: Gemini detects the language and translates the feedback if necessary.
6) **Sentiment Analysis**: The feedback is analyzed for sentiment to determine if it requires escalation.
7) **Email Subject Generation**: Gemini generates an appropriate email subject for the response.
8) **Response and Escalation**: Responses are sent via SMS or email. If the feedback is negative, it is escalated to a support agent, and Twilio Programmable Voice API initiates a call to the customer.

API link: https://telinga.koyeb.app/api/
<!--_I've disabled public registration to prevent resource exhaustion on the Twilio test account_-->
_sms notification sent after onboarding customers via the upload_csv endpoint_
_customer replies to the notification_
_automated response to customer's feedback. If feedback is negative, escalate via a call_
_call made to customer upon receipt of negative feedback_

<!-- Share a link to your app and include some screenshots here. -->
### Twilio and AI
**Twilio's Role**
Telinga uses Twilio’s powerful APIs to manage communication across multiple channels:
- **Twilio Programmable Messaging API**: Handles SMS communication, ensuring reliable message delivery to and from customers.
- **Twilio SendGrid API**: Manages email communication, enabling automated responses to customer feedback.
- **Twilio Programmable Voice API**: Manages the escalation of feedback by initiating a call to the customer with a support agent when necessary.
**Gemini AI's Role**
Telinga integrates AI to enhance communication efficiency:
- **Sentiment Analysis**: Telinga utilizes Gemini to analyze the sentiment of customer feedback, summarizing it and escalating to a support agent if necessary.
- **Email Subject Generation**: Gemini generates compelling email subjects for responses, improving open rates and customer engagement.
- **Language Detection and Translation**: Gemini automatically detects the language of the feedback and translates messages to ensure accurate responses in the customer's language.
## Additional Prize Categories
- **Twilio Times Two**
Telinga leverages *Twilio's Programmable Messaging API*, *SendGrid API*, and *Programmable Voice API* to create a seamless communication tool that bridges SMS, email, and voice interactions.
- **Impactful Innovators**
By breaking down language barriers and enhancing feedback management, Telinga provides a significant positive impact on customer experience and business operations.
## Next steps:
- Telinga's future: Bespoke business chatbots to drive engagement via chat, auto-ticket system for negative feedback and direct app integration for a seamless, data-driven customer support experience.

1,896,891 | Using yup to build schema with value parsing and validation. | Validation is a very important aspect of application development, in which user input data is tested... | 0 | 2024-06-22T11:36:12 | https://dev.to/belloshehu/using-yup-to-build-schema-with-value-parsing-and-validation-7if | webdev, validation, yup, schema | Validation is a very important aspect of application development, in which user input data is tested against a predetermined format or value to ensure accuracy and quality of data entered into the application.
There are a bunch of tools used for validating user input both in the frontend and backend applications. Among such tools is `yup`; a very popular schema builder with value parsing and validation capabilities.
Below are examples of how to use yup to build user signup schema with validation in JavaScript.
First off, we need to install `yup` and import it into the file we want to use it:
`npm i yup`
```
import * as yup from "yup";
```
**1. Building basic user signup schema**
This simple yup schema is for user signup containing user's email, password, and username. All fields are required:
```
const basic_signup_schema = yup.object({
email: yup.string().email().required("Email required"),
password: yup.string().required("Password required"),
username: yup.string().required("Username required"),
});
```
The `.string` method validates email ID to string. Whereas, the `.email` validates any email ID entered.
If this schema is used with a form library such as Formik, the individual form fields will be validated accordingly. Hence, the form will not be submitted if at least one of the fields is empty.
**2. Adding more validation to signup schema**
To make the user's password stronger and hence difficult for a hacker to guess, it must contain digits, upper and lower case, special characters and be at least 8 characters long.
```
const signup_schema = yup.object({
email: yup.string().email("Invalid email").required("Email required"),
password: yup
.string()
.min(8, "Must be 8 characters long")
.required("Password required")
.matches(/[a-z]+/, "Must contain lowercase character")
.matches(/[A-Z]+/, "Must contain uppercase character")
.matches(
/[_@$!%*#?&]+/,
"Must contain at least one special character among $ ! % * # ? & _ @ "
)
.matches(/\d+/, "Must contain digit"),
username: yup.string().required("Username required"),
});
```
**Conclusion**
Data validation is used to ensure security, and integrity of data stored in application's database. Hence, using a library such as `yup` is an effective and easier way you can ensure that the user enters correct data into your application.
For suggestions, correction and questions, kindly make a comment in the comment section.
**Thanks for reading!**

We won't rely on any third-party libraries, ensuring you gain a deeper understanding of how to handle files directly in JavaScript. By the end of this tutorial, you'll be able to preview images, text files, xlxs files, pdf files in your React application.
```
const PdfViewer = ({ url }) => {
const iframeRef = useRef(null);
const interval = useRef();
const pdfUrl = createGdocsUrl(url);
const [loaded, setLoaded] = useState(false);
const clearCheckingInterval = () => {
clearInterval(interval.current);
};
const onIframeLoaded = () => {
clearCheckingInterval();
setLoaded(true);
};
useEffect(() => {
interval.current = setInterval(() => {
try {
// google docs page is blank (204), hence we need to reload the iframe.
if (iframeRef.current.contentWindow.document.body.innerHTML === '') {
iframeRef.current.src = pdfUrl;
}
} catch (e) {
// google docs page is being loaded, but will throw CORS error.
// it mean that the page won't be blank and we can remove the checking interval.
onIframeLoaded();
}
}, 4000); // 4000ms is reasonable time to load 2MB document
return clearCheckingInterval;
}, []);
return (
<div className={css['pdf-iframe__wrapper']}>
<iframe
ref={iframeRef}
className={css['pdf-iframe__inside']}
frameBorder="no"
onLoad={onIframeLoaded}
src={pdfUrl}
title="PDF Viewer"
/>
{!loaded && (
<div className={css['pdf-iframe__skeleton']}>
<Skeleton height="100%" rectRadius={{ rx: 0, ry: 0 }} width="100%" />
</div>
)}
</div>
);
};
```
In this blog post, we created a custom file preview component using React without relying on any third-party libraries. We learned how to read file contents, and display previews .
Potential enhancements include adding support for more file types, improving the styling, and handling errors more gracefully. Happy coding!

In a solid personal connection, the job of assent couldn't possibly be more significant. Trust, respect, and open lines of communication between partners are built on consent. Relationships can quickly become harmful and toxic if consent is not given. In this article, we will look at how consent can improve the quality of the relationship as a whole and how it is crucial for healthy intimate relationships call boy job faridabad .
What is Assent?
Assent is a deliberate consent to participate in a particular action. With regards to personal connections, it alludes to the authorization given unreservedly by the two accomplices to participate in sexual exercises. Consent ought to be always enthusiastic, ongoing, and reciprocal. It's not enough to just say "yes," but also to fully comprehend and respect one another's boundaries and desires, playboy club chandigarh.
Why is consent so essential?
There are several reasons why consent is necessary for healthy intimate relationships:
Respect: Partners demonstrate respect for each other's autonomy and agency by seeking and gaining consent. It recognizes that every individual has the option to settle on conclusions about their own body playboy club delhi.
Trust: Trust between partners is built and strengthened when consent is freely given. It creates a secure setting in which both partners feel valued and respected.
Communication: One form of communication is consent. It includes transparent discourse about wants, limits, and inclinations. Partners can better comprehend each other's requirements and ensure a positive and fulfilling intimate experience by discussing consent playboy registration.
Safety: Agree assists with guaranteeing the physical and profound wellbeing of the two accomplices. It lowers the likelihood of sexual harm, abuse, and coercion. At the point when assent is available, the two accomplices can have a good sense of safety and agreeableness in their relationship call boy job coimbatore.
Open Correspondence: Discuss your limits, desires, and boundaries with your partner. Pay attention to their necessities and regard their sentiments. In order to gain and maintain consent in a relationship, communication is essential.
Check-In: During private moments, check in with your partner on a regular basis. To make sure that both partners are at ease and willing to move forward, you can inquire about nonverbal or verbal cues call boy job.
Regard Limits: Even if your partner has previously agreed to certain activities, always respect their boundaries. Consent can be revoked at any time and is not fixed. Focus on verbal and non-verbal signals that show distress or wavering playboy job.
Learn for yourself: Be learned about assent and the regulations encompassing it. Know the difference between coercion and consent. Learn how to recognize the warning signs of non-consent and how to react appropriately.
All in all, assent assumes a fundamental part in keeping up with solid and satisfying close connections. It is a foundation of regard, trust, correspondence, and wellbeing between accomplices. Partners can establish a solid and positive foundation for their relationship by practicing enthusiastic consent. Keep in mind, assent isn't simply an idea - a training ought to be embraced and maintained in every single close communication [call boy job](https://iplayboy.in/). | neha11222 |

1,604,244 | A long-winded Primer to the JavaScript Packaging Situation | If you've been dealing with the JavaScript ecosystem for more than 5 minutes you're probably aware... | 0 | 2024-06-22T11:20:35 | https://dev.to/hamishmilne/a-long-winded-primer-to-the-javascript-packaging-situation-32ho | javascript, typescript, npm | If you've been dealing with the JavaScript ecosystem for more than 5 minutes you're probably aware that the situation with modules, build systems, runtimes, bundlers, and packaging code for distribution is kind of a mess right now. The aim of this guide is to cut through some of the bullshit, give a bunch of somewhat opinionated recommendations and end with a simple decision tree to let anyone determine what to write, what to distribute, and how to do it.
First off, some key assumptions (aka, my opinions):
## 0. These are (just) my opinions
I believe, quite strongly, that the approach outlined here should be used for all new JS projects. There will, *inevitably*, be certain niche or legacy situations where you will *have* to, for example, use UMD modules or TypeScript's 'import require' syntax. I'll try to note any examples where I've personally come across them, and of course feel free to comment your own if you have any.
## 1. We are using TypeScript
Seriously, at this point there is *precious* little reason to not use TypeScript as your source language. The tooling is robust, the language itself is excellent, there's wide support in the ecosystem, and it's got first-class support in Bun (i.e. the probable NodeJS replacement).
If you *really* love runtime errors and want to see more of them in your code, you can set [`"strict": false`](https://www.typescriptlang.org/tsconfig#strict) in tsconfig and just... write JavaScript. Then, to be serious for a moment, you can gradually adopt type annotations as your project grows - and you'll have the systems in place to support it.
In a few places, I'll be mentioning [`ts-node`](https://typestrong.org/ts-node/), which is a module for NodeJS that adds a special 'loader' for TypeScript files. In essence, if you run Node with the right options (`node --loader ts-node/esm` typically) you'll get pretty robust, seamless TypeScript support - no need for separate build steps. If it's at all applicable, you should use it.
With all that said, I highly recommend *against* *distributing* raw TypeScript. At the end of the day, TypeScript is still an additional dependency that we don't want to impose on library consumers. There's also a plethora of configuration options that may cause distributed TypeScript to simply not work in a given downstream project.
## 2. We don't care about UMD, AMD, SystemJS etc.
For those not in the know, there are two 'module systems' (i.e. ways of telling the runtime what values to import and export from a given file) in common use right now. The normal, standard-since-2015, fully-featured, widely-adopted 'ECMAScript Module' syntax, or ESM for short:
```js
import { foo } from "foo";
export async function bar() {
const { baz } = await import("baz");
}
```
and the old, outdated, legacy system used by NodeJS, called CommonJS (or CJS):
```js
const { foo } = require("foo");
function bar() {
const { baz } = require("baz");
}
module.exports = { bar }
```
There were once a whole plethora of alternative module systems: UMD, AMD, and SystemJS, but these are now historical footnotes. The only time you will encounter them is if someone has packaged a library using them (God help you!). You should never, in the current year, distribute code that uses them.
And to be absolutely clear: the only reason we are even mentioning CommonJS is because the NodeJS implementation of ESM has, at the time of writing, several critical compatibility issues that are unlikely to be resolved in the near future, which will be explained in the relevant sections later on.
And if you're using [Bun](https://bun.sh/), rejoice - you can mix and match both systems in the same file:
```js
import { foo } from "foo";
const { bar } = require("bar");
```
Not that you would want to, of course, but it's probably the best solution to the problems we'll be discussing.
## 3. We are aiming for simplicity, compatibility, and robustness
* We want our emitted JS code to be as close to our TypeScript as possible.
* We don't want superfluous distribution files, or long build processes, or a load of extra dependencies.
* We want the code to work in every situation - as long as it doesn't conflict with the first two goals.
# The problem with ESM in NodeJS
NodeJS uses CommonJS internally, and probably always will. Node's ESM support uses a special API hook called a 'loader', which is responsible for essentially translating your ESM files into CJS under the hood.
There are, of course, several problems with this approach. Notably, you can't really configure it so that multiple loaders act on the same file, as a user. `ts-node` has to use a special implementation to get ESM compatibility on Node, which is why you need `ts-node/esm`. Likewise for Yarn's PnP system (though in that case it's the default). If you want to use both together, you're SOL.
The second thing to remember is that ESM imports are inherently asynchronous, with top-level `await` and so on, whereas Node's `require` is a synchronous call. Evidently, Node's execution pipeline is inflexible enough that this presented an enormous problem for the devs, and the result: you can't `require` ESM files in Node. The reverse isn't true, fortunately - you can `import` CJS files no problem (well, some problems, but that's for later).
In short:
```js
import foo from "./foo.cjs"; // Works!
const { bar } = require("./bar.mjs"); // Error!
```
The upshot is if you're writing apps and tools, you can, and *should* run ESM natively. If you transpile to CJS, you won't be able to use ESM-only dependencies (without using `await import`, which is a *whole* other can of worms and will probably make your APIs unusable).
But for libraries, where you have no idea if they'll be imported from an ESM or CJS context, you'll need to distribute your package as CJS by transpiling your ESM code (with `tsc`, ideally). Note that in this case, **ESM-only dependencies will not work** but they are, fortunately, quite rare.
In all cases I've found, this transpiled CJS code will work just fine in bundlers like Webpack and Vite - in the latter case it'll get converted *back* to ESM, funnily enough. The sole exception is Deno, which *does* use ESM internally and won't like your CJS code. If you want to support Deno, bundlers, *and* Node at runtime, there's no way around it: you'll have to multi-target CJS and ESM. But we'll get to that later.
In conclusion: Node's ESM support sucks. At the very, very least, it's now officially 'stable'; the 'experimental' warnings you might remember in the Node CLI have gone away as of v20.
# Configuration recommendations
I'm going to be covering a few different types of JS project:
* Frontend/web apps, [IIFE](https://en.wikipedia.org/wiki/Immediately_invoked_function_expression) bundles
* Backend/server-side apps, tools, and local scripts
* Libraries
* Some of which may need to run on NodeJS
Each of these has different requirements, so keep them in mind as you follow along.
## A note on import statements and file extensions
What's the correct way to write imports of local files? It's easy, right?
```js
import { foo } from "./foo"; // Works... sometimes!
```
The thing to remember is that **module resolution is not standardised across consumers**. All you're doing is telling whatever program is consuming your code - `tsc`, Node, Webpack, etc. - to please give you the module object for `./foo`, whatever that is. This is how when you import `react`, Node will look inside `node_modules` and load `node_modules/react/index.js` or whatever.
First off, if you're importing a local file, always begin the import specifier with `./` or `../`; this ensures there's no ambiguity with packages, and in my experience, makes tooling much more reliable. Don't try to mess with tsconfig to add multiple source roots, or do `src/foo` or somesuch - you'll end up tying yourself in knots and run into all sorts of errors down the line. Stick to relative paths.
Secondly, you need to be extremely cognizant of file extensions. This applies both to local files, and when deep-linking into a package to import a particular file (but not to directories or package roots). TypeScript, bundlers, [Bun](https://bun.sh/docs/runtime/modules#syntax), and [Node's `require`](https://nodejs.org/api/modules.html#modules_file_modules) statements will search for the file in question, trying different file extensions in a particular order until they get a match.
Deno and Node's ESM implementation, however, do *not* do this. They require the file to be specified exactly, including the specific file extension to use.
Sounds reasonable - in the former cases, you aren't *forbidden* from specifying the extension, it's just optional. So we just need to start using `import "./foo.js"` and everything should still work... right?
But we aren't writing JavaScript. We're writing TypeScript. So what should we use to import a local file - `.ts`, or `.js`?
The sad reality is that no option will work in all cases.
In the IDE, you can use either: for `.js`, TypeScript will 'magically know' to convert this to `.ts` under the hood... ugh. You can also leave off the extension entirely, if TypeScript is configured to let you do this.
If you're using `ts-node` with `type: module`, or Deno with TypeScript directly, you have to use `.ts` because the `.js` files don't exist on disk (the runtime will take care of the conversion).
If you're manually transpiling to ESM JavaScript, then running on Node, you have to use `.js`, because of course the `.ts` files don't exist (and Node wouldn't understand them in any case).
If you're manually transpiling to CJS, you can use `.js`, or leave off the extension.
If you're using a bundler that accepts TypeScript directly, like Webpack, you'll have to use `.ts` because the `.js` doesn't exist on disk. There are probably ways to rectify this with custom resolution rules etc. but that's out of scope for now.
One 'simple' fix that comes to mind is simply rewriting import statements at build time from `*.ts` (or blank) to `*.js`. The TypeScript devs, however, [have explicitly rejected this](https://github.com/microsoft/TypeScript/issues/49083#issuecomment-1435399267) as a solution - and their reasons do seem pretty solid.
So, what's the TL;DR here?
For libraries, **you should specify `.js`** because you'll be building JS files from your TS source anyway.
For bundlers/front-end, **you should leave off the extension, or use `.ts`**. In this case you may need to set `"moduleResolution": "Bundler"` as described below.
For server-side that uses `ts-node`, **you should specify `.ts`**.
For server-side where you're pre-building your JS, **you should specify `.js`**.
## `type`, `module`, and `moduleResolution`
These three fields, the first in package.json and the others in tsconfig.json, determine and are determined by the module system your compiled JavaScript will use. Despite them being three separate fields they are in fact very tightly linked, and only certain combinations will work.
`type` is used by both Node and TypeScript to decide what module system `.js` and/or `.ts` files use. If left unset, or set to `"commonjs"` it will assume they're CJS. If set to `"module"` it will assume they're ESM.
* For libraries targeting Node and therefore emitting CJS, you should set it to `commonjs`.
* In all other cases, use `module`.
The setting can be overridden on a per-file basis by using `.cjs` and `.cts` to for CJS code, and `.mjs` and `.mts` for ESM code. This is useful, but these extensions are not as widely-supported and there are pitfalls associated with using them.
[`moduleResolution`](https://www.typescriptlang.org/tsconfig#moduleResolution) determines how TypeScript resolves type information from an `import` operand, and ensures that these operands are specified correctly.
* For server-side, we need to use `Node16`, since this allows us to import both ESM and CJS and will give compile errors when we fail to specify a file extension.
* For libraries building to CJS, we need to use `Node10`, since that's the only option allowed when doing so.
* For front-end, or libraries only targeting front-end, you should use `Bundler`, which is similar to `Node16` but more permissive.
[`module`](https://www.typescriptlang.org/tsconfig#module) determines which module system `tsc` will use in the emitted JS.
* For server-side, we need to use `Node16` because this is the only option when `moduleResolution` is correctly set for this.
* For libraries building to CJS we should, of course, use `CommonJS`.
* For other libraries, you should use `ES2015`.
* And for front-end you can use `ES2022`, or otherwise the latest version.
## So, what do I save my source files as?
If you follow the steps above, you should save your files as `.ts`, as normal.
## `target` and `lib`
`target` tells `tsc` whether it needs to down-level newer JavaScript features to support older runtimes.
For any app or tool in which you control the runtime environment, you should set it to the latest: `ES2022` at the time of writing.
For libraries, or code that gets distributed like a dev tool, you should start with `ES2018` (essentially ES2015 but with async functions and object-spread expressions, both supported since Node v10) and only increment it as needed.
The `lib` option should be kept in sync with `target` (aside from the addition of `DOM`, `DOM.Iterable` for front-end).
## `isolatedModules` and `verbatimModuleSyntax`
Turning TypeScript into JavaScript is, in most cases, quite straightforward: find any syntax that related to the type system, and delete it. This works because TypeScript was always designed to be a strict superset of JavaScript, and it's great because the JavaScript we emit is extremely close to the source code. So if sourcemaps aren't working you can still debug, and you don't need to worry about `tsc` introducing bugs into your code.
Of course if you're targeting CJS you need to turn all your `import`s into `require`s, but that's pretty straightforward to do, and in any case we'll deal with the pitfalls later on.
When `tsc` runs, it needs to load up every file in the project in order to type-check everything. If successful, it then emits the JS code for every file. Other tools, like swc, esbuild, and Vite, don't do this: they process each file individually and in parallel, without type-checking, often in response to those specific files being changed. As you can imagine this is enormously faster. You can then run `tsc` on a slower cadence, without emitting JS. This is known as 'SFC' for Single-File Compilation.
However, there are a couple of TypeScript language features that don't fit this pattern: `namespace` and `const enum`. I won't go into details here, but suffice it to say that these are now largely considered mistakes, and will often cause errors if your TypeScript is consumed by anything other than `tsc`.
**To fix this, you should always enable `isolatedModules` in tsconfig, which makes it an error to use any of these features.**
The second problem relates to importing types. [The documentation](https://www.typescriptlang.org/tsconfig#verbatimModuleSyntax) goes into detail, but the short version is that, when importing, you should be explicit about importing a type, compared to a runtime value.
```typescript
// Instead of this:
import { some_type, some_value } from "foo";
import { other_type } from "bar";
// Use this:
import { type some_type, some_value } from "foo";
import type { other_type } from "bar";
```
What's the difference between `import type { foo }` and `import { type foo }`? The first one will get removed entirely from the output, whereas the second one will become `import {}`. This is crucial to remember if module initialization order matters - for example if a module has any side effects (it's extremely bad practice, but... it happens).
My personal advice: if you're importing modules with side effects, use `import "foo";` with a comment to explain; ideally at the very top of your program.
**The setting `verbatimModuleSyntax` will helpfully enforce the use of `import type` for us, so you should absolutely enable it in tsconfig.**
BUT!
When `verbatimModuleSyntax` is enabled, `tsc` will - *bafflingly* - refuse to emit CJS code! The documentation implies that this is a deliberate design choice, which is very silly indeed.
This means that, if we're targeting CJS, we need to do a little dance with the compiler by defining a secondary tsconfig that we'll call `tsconfig-cjs.json`:
```json
{
"extends": "./tsconfig.json",
"compilerOptions": {
"verbatimModuleSyntax": false,
"module": "CommonJS"
}
}
```
We'll then need to set `"module": "ES2018"` in the main tsconfig, so that the IDE doesn't complain. The build command will be `npx tsc -p ./tsconfig-cjs.json`.
## LFANs, `esModuleInterop`, and `allowSyntheticDefaultImports`
Normally, when converting ESM to CJS the rules are pretty straightforward:
```js
// src/index.ts
import { foo } from "foo";
import * as bar from "bar";
import baz from "baz";
import bat1, { bat2 } from "bat";
// dist/index.cjs
// ... Okay, it's not *exactly* this, there's normally some extra cruft, but semantically this is what you get.
const { foo } = require("foo");
const bar = require("bar");
const { default: baz } = require("baz");
const { default: bat1, bat2 } = require("bat");
```
Note a couple of things here:
* a 'Default Import' (`import baz`) in ESM is the same as accessing the `default` property of the module object in CJS
* a 'Namespace Import' (`* as bar`) in ESM is the same as just assigning the whole module to a variable in CJS
These are both true because the CJS export syntax is simply:
```js
module.exports = { foo, default: bar };
```
This is all fine, but CJS doesn't restrict `module.exports` to only objects - it can be anything you like, a string, a number, a function. Indeed, a common pattern historically was to define modules like so:
```js
// package.js
module.exports = function PackageFactory() { }
// index.js
const PackageFactory = require("package");
const myPackage = PackageFactory();
```
**Let's call this a... Legacy Function-As-Namespace Module. LFAN for short.**
Of course, it's not possible to define LFANs in ESM, but we can at least consume them: simply use `import * as PackageFactory from "package"`.
However... this is *technically* invalid according to the ESM spec! ESM namespaces are immutable object-like things and must *never* be callable!!!1!
Therefore, transpilers like `tsc`, `esbuild`, `swc`, and Babel, will usually [generates a lot of cruft](https://www.typescriptlang.org/tsconfig#esModuleInterop) in CJS output in order to 'fix' this 'problem', which is controlled with the `esModuleInterop` setting.
There are, roughly speaking, two methods used to do this:
* When importing a CJS module which has no `default` field, set `module.exports.default = module.exports`, OR
* Create a new, immutable object, copying over only the owned properties of `module.exports`, if any, and setting the value of `default` to `module.exports` itself.
`tsc`, `esbuild`, and `swc` use the first option, which is more efficient and compatible, since it ends up that a Default Import and a Namespace Import will provide the same value. Node's ESM runtime and Babel use the second, which is more spec-compliant, since *only* a Default Import will work - a Namespace Import will return an object like `{ default: moduleFunction }`, which is probably not what you expect.
From what I can tell, only `tsc` allows you to turn this 'feature' off entirely, by disabling `esModuleInterop`.
TypeScript's `allowSyntheticDefaultImports` mirrors this runtime behaviour in the type system. When enabled, TypeScript relaxes its checking of import statements very slightly, such that for any module that lacks an explicit 'default' export, a 'synthetic' one is created that just aliases the whole module. Unfortunately there's no way to forbid Namespace Imports in this situation, so if you're targeting Node's ESM or Babel you just need to be careful.
```js
import * as moment from "moment";
import moment from "moment"; // allowed when allowSyntheticDefaultImports=true
```
So, in general:
* If you know that you have no LFAN dependencies, OR
* You are only targeting CJS, and don't intend to run your source code through `esbuild`, `swc`, or Babel,
then you can (and should) disable both `esModuleInterop` and `allowSyntheticDefaultImports`. **Otherwise, you will have to enable them both to prevent compatibility issues down the line, and be sure to only use Default Imports for LFANs**.
Note that, for CJS emits, TypeScript will always output the following:
```js
Object.defineProperty(exports, "__esModule", { value: true });
```
This just sets a flag that allows consumers that use `esModuleInterop` (and similar) to be a little more efficient.
## Other, miscellaneous options
You should enable [`composite`](https://www.typescriptlang.org/tsconfig#composite), and set your `include` patterns appropriately. This will also enable [`incremental`](https://www.typescriptlang.org/tsconfig#incremental) (making your builds faster), so remember to add `.tsbuildinfo` to gitignore. If all your code is in some directory, e.g. `src`, make sure to set `rootDir` to that aforementioned directory.
You will probably want to enable [`skipLibCheck`](https://www.typescriptlang.org/tsconfig#skipLibCheck). Packages can include all sorts of TypeScript code which may or may not be valid for your current TypeScript version and compilation options, so using this saves a lot of headaches. Note you'll still have type-checking on your *imports* of library code - this just tells `tsc` to not bother checking the library declaration files themselves for correctness.
There are various other useful options like `forceConsistentCasingInFileNames` but these all come with sensible defaults.
And finally you should, of course, enable [`strict`](https://www.typescriptlang.org/tsconfig#strict) in tsconfig.
# Build, run, distribute
## You should use `ts-node`
**For server-side apps, or local scripts, this is without a doubt the best approach.** It's simple, robust, and removes whole classes of potential errors.
With everything set up as described above, you'd just run `node --loader ts-node/esm ./my_file.ts`. Debugging in VSCode 'just works'. I like to use the JavaScript Debug Terminal as it saves having to create `launch.json`.
If `ts-node` is all you need, you should enable [`noEmit`](https://www.typescriptlang.org/tsconfig#noEmit) in tsconfig, and use `tsc` as essentially a linter. This prevents JavaScript files from being created accidentally.
If you're using Yarn, remember to set [`nodeLinker: node-modules`](https://yarnpkg.com/configuration/yarnrc#nodeLinker) in yarnrc, for the reasons mentioned above about Node's ESM support sucking.
The only `ts-node` specific option I'd recommend is [`transpileOnly`](https://typestrong.org/ts-node/docs/options/#transpileonly). You probably don't need `swc`, but if startup performance is really critical you might consider it.
There are of course certain situations where `ts-node` isn't an option. Maybe you *really* want to use Yarn PnP, or you're distributing a dev tool where you want to minimise your runtime dependencies. In that case...
## Emitting ESM
**You'll need to do this for dev tools, and for libraries which don't target Node as a runtime (or do, but have ESM-only dependencies).**
With everything configured as above, just set [`outDir`](https://www.typescriptlang.org/tsconfig#outDir), and run `tsc` to build. If you take a look at the emitted JavaScript you'll see that it's extremely close to your source code.
For an app, you can then run `node ./dist/main.js` as normal. You should explicitly set [`declaration`](https://www.typescriptlang.org/tsconfig#declaration) to false, since you're not expecting anyone to consume your type information, and it'll speed up your build process.
For a library, you'll want to set two fields in package.json, `main` and `types`, which should point to `/dist/index.js` and `/dist/index.d.ts` respectively. This allows consumers to import your library and get the root module.
## Emitting CJS
**You'll need to do this for libraries that target Node, but not Deno, and don't have any ESM-only dependencies.**
After following the steps described in the `verbatimModuleSyntax` section above, you should already have a `tsconfig-cjs.json` file. Simply run `npx tsc -p ./tsconfig-cjs.json` and you'll have your output.
## Multi-targeting CJS and ESM
**You'll need to do this if you want to target both Node and Deno.**
Since CJS is the 'lowest common denominator' it will be your primary target, with ESM being built specifically for Deno. Follow all the steps above assuming you're targeting CJS alone.
In `tsconfig-cjs.json`, set your `outDir` to `dist/cjs` or similar. Set `main` and `types` in package.json accordingly. Then in your main `tsconfig.json`, set `outDir` to `dist/esm` or similar.
We can then run `npx tsc` for ESM, and `npx tsc -p ./tsconfig-cjs.json` for CJS.
Remember: since we've set `type: commonjs`, if you try to import the contents of `dist/esm` in Node you'll get an error. Of course there's no reason to do this when the CJS target works just fine and is more compatible in any case. The only consumers of this target will be those that outright do not support CJS (i.e. Deno).
Newer versions of Node use a field called [`exports`](https://nodejs.org/docs/latest-v18.x/api/packages.html#conditional-exports) in package.json, which is supposed to allow CJS contexts to get a CJS module, and ESM contexts to get an ESM module. I don't see much value in this when we know CJS works all the time; it just seems like it'll make testing harder.
# Things to avoid
## Don't use `export =` or `import foo = require`
Before TypeScript supported ESM, there was some special syntax to define a CJS module's imports and exports:
```typescript
// .ts
import foo = require("foo");
export = { bar };
// .js
const foo = require("foo");
module.exports = { bar };
```
... Yep, that's really all it does. Honestly I don't see the point.
In any case, this syntax is still available today, and it's the only way to define a 'raw' CJS module in TypeScript, rather than an ESM module which is then converted to CJS. As you might imagine, **you can only target CJS when using this syntax**.
Furthermore, though the [documentation](https://www.typescriptlang.org/docs/handbook/modules.html#export--and-import--require) doesn't call this out, there's no way to import or export type-only declarations (`type` and `interface`) with this syntax.
There are exactly two reasons why you'd want to use this rather than ESM:
* You really hate the presence of `Object.defineProperty(exports, "__esModule", { value: true });` in the output (with this syntax it won't be emitted)
* You want to define an LFAN, so you need a way to directly control the value of `module.exports`
Neither of these are very good reasons.
## Don't bundle libraries for distribution
Some library authors follow the practice of bundling some or all of a library's local files and/or package dependencies into the output. There is really only one valid purpose for doing this, and that's when you're creating a bundle for legacy web development - the sort where you write `<script>` tags to include your dependencies then manually bash out the JavaScript.
This is, of course, a very outdated technique and should be discouraged at every opportunity in favour of just... using NPM. However, if it does become necessary, you need to create a global-setting IIFE bundle, as with Webpack's [`type: global`](https://webpack.js.org/configuration/output/#type-global) or `esbuild`'s [global name](https://esbuild.github.io/api/#global-name). This bundle can be distributed in addition to a standard NPM package. You should under no circumstances use something like UMD; CommonJS consumers should always use packages.
In all other cases, there is absolutely no reason to do this. It complicates dependency management, makes debugging harder, and requires additional tooling for no real benefit in kind.
## Be extremely careful with `await import`
The `await import` syntax is ESM's method of defining a 'dynamic import' - that is, an import that happens during the program flow, rather than immediately on startup.
The most common use of this syntax is for 'code splitting' on the front-end: JS bundles tend to be rather large, so this allows you to lazy-load parts of your app to make your initial page load faster (the bundler is responsible for figuring out how this works underneath).
The other use case is specific to NodeJS. The Node runtime provides `await import` in ESM contexts... **but also in CJS contexts**. And, unlike `require`, **you can import *any* kind of module using it**, both ESM and CJS. So the upshot is that, under Node, this is the only way to import an ESM module into a CJS context.
Let's consider an example dependency diagram:
```
main.mjs
┣━ import 'A.mjs'
┃ ┗━ import 'B.cjs'
┃ ┗━ require('C.cjs')
┗━ import 'D.cjs'
┗━ await import('E.mjs')
```
In order to import module E in the context of module D, we have to use `await import`. It's a useful escape hatch for the very few cases where you have no other options.
However, you do have other options!
* **If you're making a server-side app, just use ESM directly as recommended earlier.** There's no reason not do do this now that Node's ESM is considered stable.
* **If you're making a library, and you *really* can't get rid of this ESM-only dependency, just make your library ESM-only too.** While this does just kick the problem further up the chain, your consumers *can also* just use ESM directly. In other words, if anyone complains, direct them to the point above.
The problem is that `await import` is really, really awful to use outside of code-splitting. You end up with code like this:
```js
// there are other ways, but this is probably the most elegant
async function doImports() {
return {
bar: await import("bar.mjs"),
baz: await import("baz.mjs"),
}
}
// note that all our exports need to be async functions now.
// want to export sync functions, or constants? You're SOL.
export async function myFunc() {
const { bar } = await doImports();
// etc.
}
```
This is, to put it lightly, horrible.
## Don't downlevel to ES5
ES2015, aka ES6, has been standardised since (as the name implies) 2015. NodeJS has been [99% compliant since version 8](https://node.green/). Any browser version released after 2016, **eight years ago**, [fully supports it](https://caniuse.com/?search=es6).
The *only* reason to target ES5 is to support ancient, insecure, unsupported browsers like IE11. If this applies to you, I understand that it's unlikely to be by choice, so you have my sympathies :)
# A note on unit testing
Traditionally, the received wisdom for TypeScript unit testing was to use [`ts-jest`](https://kulshekhar.github.io/ts-jest/). However, Jest is kind of enormous and brittle with a huge amount of configuration for some reason, and in my experience getting both [TypeScript](https://kulshekhar.github.io/ts-jest/docs/guides/esm-support/) and [ESM](https://jestjs.io/docs/ecmascript-modules) to work with Jest really quite painful.
For that reason, **I highly recommend [Vitest](https://vitest.dev/)**. It's compatible with Jest's API and has both TypeScript and ESM support out of the box.
**If you really have to use Jest for some reason, you should target CJS** and save yourself a lot of headaches.

Welcome to this iHateReading newsletter. Read directly on [website](ihatereading.in)
Well, I always worry about covering all the domains of software development in my newsletter. I even try to put things is simple words so that non-developers in this subscribers list will also be able to understand at least the nuances.
Let's begin with Web3 today because I'ven't talked about anything related to web3 app development and surprisingly I have been working in the web3 domain for the past 2 years.
All about Web3 || Blockchain
============================
When I was entering into web3 domain the first question as a developer was what's the application, I read tonnes of blogs then back, I am taking about 2 years ago and recently got this blog on [10 Unusual Blockhain applications](https://www.erlang-solutions.com/blog/10-unusual-blockchain-use-cases/?ref=dailydev#Bjorn_Borg_and_same-sex_marriage).
I started the [blockchain development journey](https://medium.com/coinmonks/learning-blockchain-development-32222c234557) by simply reading about the basics and developing a small few-hour project.
But after researching and reading the basics I found the technology under the hood is different and that doesn't affect much on frontend or client side, more often the changes are in the backend domain and of course if you writing smart contract then you have to switch to solidity as the programming language.
[Web3 and Solidity Roadmap](https://vitto.cc/web3-and-solidity-smart-contracts-development-roadmap/)
Here is the basic roadmap for blockchain development ,[https://roadmap.sh/blockchain](https://roadmap.sh/blockchain)
Once you get the basics my advice is to create a small project using Moralis to understand the concepts well.
[https://docs.moralis.io/web3-data-api/evm/quickstart-nextjs](https://docs.moralis.io/web3-data-api/evm/quickstart-nextjs)
Some of the most used npm packages in web3 are the following ones
[ether.js](https://docs.ethers.org/v5/)
[web3.js](https://web3js.readthedocs.io/en/v1.10.0/)
my personal react npm module for web3 provides tonnes of hooks and features to develop easily, [Wagmi](https://wagmi.sh/).
Web3 for backend development needs solidity to get started, [here is the introduction](https://youtu.be/IkCfIE1VoRo).
[Truffle](https://archive.trufflesuite.com/) and [Hardhat](https://hardhat.org/) both are quiet and commonly used packages

1,896,900 | Creating a Custom useForm Hook in React for Dynamic Form Validation | Managing form state and validation in React can often become cumbersome, especially when dealing with... | 0 | 2024-06-22T11:14:17 | https://dev.to/sumitwalmiki/creating-a-custom-useform-hook-in-react-for-dynamic-form-validation-595f | Managing form state and validation in React can often become cumbersome, especially when dealing with complex forms and nested fields. To simplify this process, creating a custom useForm hook can be incredibly beneficial. In this article, we'll walk through the creation of a useForm hook that handles validation, form state management, and error handling in a reusable and dynamic manner.
**The useForm Hook**
Let's start by defining the useForm hook. This hook will manage the form's state, handle changes, reset the form, and validate fields based on the rules passed to it.
```
import { useState } from "react";
import validate from "../validate";
const useForm = (
initialState,
validationTypes,
shouldValidateFieldCallback,
getFieldDisplayName
) => {
const [formData, setFormData] = useState(initialState);
const [errors, setErrors] = useState({});
const [showErrors, setShowErrors] = useState(false);
const onHandleChange = (newFormData) => {
setFormData(newFormData);
};
const onHandleReset = () => {
setFormData(initialState);
setErrors({});
setShowErrors(false);
};
const shouldValidateField = (name) => {
if (shouldValidateFieldCallback) {
return shouldValidateFieldCallback(name, formData);
}
return true; // Default behavior: always validate if no callback provided
};
const validateAll = (currentFormData = formData) => {
let allValid = true;
const newErrors = {};
const traverseFormData = (data) => {
for (const key in data) {
if (Object.prototype.hasOwnProperty.call(data, key)) {
const value = data[key];
const fieldName = key;
if (typeof value === "object" && value !== null && !Array.isArray(value)) {
traverseFormData(value);
} else if (shouldValidateField(fieldName)) {
const validationType = validationTypes?.[fieldName];
if (validationType) {
const displayName = getFieldDisplayName(fieldName);
const errorElement = validate(value, validationType, displayName);
if (errorElement) {
allValid = false;
newErrors[fieldName] = errorElement;
}
}
}
}
}
};
traverseFormData(currentFormData);
setErrors(newErrors);
return allValid;
};
const onHandleSubmit = (callback) => (e) => {
e.preventDefault();
setShowErrors(true);
if (validateAll()) {
callback();
}
};
return {
formData,
errors,
showErrors,
onHandleChange,
onHandleSubmit,
onHandleReset,
};
};
export default useForm;
```
**Explanation**:
Initial State Management: We start by initializing the form state and errors using the useState hook.
Change Handling: onHandleChange updates the form state based on user input.
Reset Handling: onHandleReset resets the form state to its initial values and clears errors.
**Validation**: validateAll traverses the form data, checks validation rules, and sets error messages if any validation fails.
Submission Handling: onHandleSubmit triggers validation and, if successful, executes the provided callback function.
The validate Function
The validate function is responsible for performing the actual validation checks based on the rules specified.
```
import React from "react";
import { capitalize } from "lodash";
import { constant } from "../constants/constant";
const validate = (value, validationType, fieldName) => {
if (!validationType) {
return null; // No validation type specified
}
const validations = validationType.split("|");
let errorMessage = null;
// Patterns
const emailPattern = constant.REGEX.BASICEMAILPATTERN;
const alphaPattern = constant.REGEX.APLHAONLYPATTERN;
for (const type of validations) {
const [vType, param] = type.split(":");
switch (vType) {
case "required":
if (value === "" || value === null || value === undefined) {
errorMessage = `${capitalize(fieldName)} field is required.`;
}
break;
case "email":
if (value && !emailPattern.test(value)) {
errorMessage = `${capitalize(fieldName)} must be a valid email address.`;
}
break;
case "min":
if (value.length < parseInt(param)) {
errorMessage = `${capitalize(fieldName)} must be at least ${param} characters.`;
}
break;
case "alphaOnly":
if (value && !alphaPattern.test(value)) {
errorMessage = `${capitalize(fieldName)} field must contain only alphabetic characters.`;
}
break;
default:
break;
}
if (errorMessage) {
break;
}
}
return errorMessage ? <div className="text-danger">{errorMessage}</div> : null;
};
export default validate;
```
Usage Example
Here's how you can use the useForm hook in a form component:
```
import React from "react";
import useForm from "./useForm"; // Adjust the import path as needed
const MyFormComponent = () => {
const initialState = {
UserID: 0,
UserEmail: '',
FirstName: '',
LastName: '',
LicencesData: {
LicenseType: null,
EnterpriseLicense: null,
IsProTrial: null,
CreditsBalance: null,
EAlertCreditsAvailable: null,
StartAt: null,
EndAt: null,
},
};
const validationTypes = {
UserEmail: "required|email",
FirstName: "required|alphaOnly",
LastName: "required|alphaOnly",
"LicencesData.LicenseType": "required",
"LicencesData.StartAt": "required",
"LicencesData.EndAt": "required",
};
const shouldValidateFieldCallback = (name, formData) => {
if (name === "Password" && formData.IsAutogeneratePassword) {
return false;
}
if (["LicencesData.StartAt", "LicencesData.EndAt"].includes(name) && formData.LicencesData.LicenseType?.value === 2) {
return false;
}
return true;
};
const getFieldDisplayName = (fieldName) => {
const displayNames = {
UserEmail: "Email",
FirstName: "First name",
LastName: "Last name",
"LicencesData.LicenseType": "License type",
"LicencesData.StartAt": "Start date",
"LicencesData.EndAt": "End date",
};
return displayNames[fieldName] || fieldName;
};
const { formData, errors, showErrors, onHandleChange, onHandleSubmit, onHandleReset } = useForm(
initialState,
validationTypes,
shouldValidateFieldCallback,
getFieldDisplayName
);
return (
<form onSubmit={onHandleSubmit(() => console.log("Form submitted successfully!"))}>
<div>
<label>Email:</label>
<input
type="text"
name="UserEmail"
value={formData.UserEmail}
onChange={(e) => onHandleChange({ ...formData, UserEmail: e.target.value })}
/>
{showErrors && errors.UserEmail}
</div>
<div>
<label>First Name:</label>
<input
type="text"
name="FirstName"
value={formData.FirstName}
onChange={(e) => onHandleChange({ ...formData, FirstName: e.target.value })}
/>
{showErrors && errors.FirstName}
</div>
<div>
<label>Last Name:</label>
<input
type="text"
name="LastName"
value={formData.LastName}
onChange={(e) => onHandleChange({ ...formData, LastName: e.target.value })}
/>
{showErrors && errors.LastName}
</div>
<div>
<label>License Type:</label>
<input
type="text"
name="LicencesData.LicenseType"
value={formData.LicencesData.LicenseType || ""}
onChange={(e) => onHandleChange({ ...formData, LicencesData: { ...formData.LicencesData, LicenseType: e.target.value } })}
/>
{showErrors && errors["LicencesData.LicenseType"]}
</div>
<div>
<label>Start Date:</label>
<input
type="text"
name="LicencesData.StartAt"
value={formData.LicencesData.StartAt || ""}
onChange={(e) => onHandleChange({ ...formData, LicencesData: { ...formData.LicencesData, StartAt: e.target.value } })}
/>
{showErrors && errors["LicencesData.StartAt"]}
</div>
<div>
<label>End Date:</label>
<input
type="text"
name="LicencesData.EndAt"
value={formData.LicencesData.EndAt || ""}
onChange={(e) => onHandleChange({ ...formData, LicencesData: { ...formData.LicencesData, EndAt: e.target.value } })}
/>
{showErrors && errors["LicencesData.EndAt"]}
</div>
<button type="submit">Submit</button>
<button type="button" onClick={onHandleReset}>Reset</button>
</form>
);
};
export default MyFormComponent;
```
**Conclusion**
With the custom useForm hook, managing form state and validation in React becomes much more manageable. This hook allows for flexible and dynamic form handling, ensuring that your forms are easy to maintain and extend. By following the patterns outlined in this article, you can create robust form handling logic for any React application.

It is characterized by the inability to achieve or maintain an erection sufficient for satisfactory s*xual performance. Cenforce 100 mg has been proven to be a leading and effective treatment for ED, providing relief to many men suffering from this condition. This medication is known for its effectiveness, safety, and affordability, making it a popular choice among patients and healthcare providers.
[Cenforce 100](https://www.genericpharmamall.com/product/cenforce-100-mg-sildenafil/) mg is a medicine that contains sildenafil citrate as its active ingredient. Sildenafil citrate is a well-known PDE5 inhibitor, the same active ingredient as Viagra. It is used to treat ED by increasing blood flow to the p*nis, thereby facilitating an erection during s*xual arousal.
Sildenafil citrate, the active ingredient in Cenforce 100 mg, works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). PDE5 breaks down cyclic guanosine monophosphate (cGMP), a substance that promotes relaxation of smooth muscle in the corpus cavernosum of the p*nis. By inhibiting PDE5, sildenafil citrate prevents the breakdown of cGMP, allowing increased blood flow to the p*nis during s*xual arousal. This process helps to achieve and maintain an erection.

---
In this article, we are going to have an initial technical view of how to install Tekton and set up your first pipeline, diving deep into every detail.
Remember that this is not our first article about Tekton. If you want to learn how it works internally, there is an article by Kirill Shirinkin called ["What is Tekton"](https://mkdev.me/posts/what-is-tekton-and-how-it-compares-to-jenkins-gitlab-ci-and-other-ci-cd-systems), so I recommend you first read this article and then come back here.
Let's start with Tekton, our powerful Kubernetes-native tool for building CI/CD systems.
First, we are going to install Tekton on our Kubernetes cluster.
```
kubectl apply --filename https://storage.googleapis.com/tekton-releases/pipeline/latest/release.yaml
```
By running this command, we're applying a set of resources that Tekton needs to operate. This lays the foundation that will allow us to create and run pipelines in the future.
To ensure everything is in order, we'll check the pods in the 'tekton-pipelines' namespace. If Tekton was installed correctly, we should see several running pods.
```
kubectl get pods --namespace tekton-pipelines
```
Perfect! The pods you see are Tekton's internal components, working together to enable us to define and run pipelines.
A pipeline in Tekton consists of 'Tasks', which define specific steps of work. Think of a 'Task' as an individual function, and a pipeline as a series of those functions running in a specific order or parallel, as defined.
Let's define our first 'Task'. This will be a simple 'Hello World'.
```
apiVersion: tekton.dev/v1beta1
kind: Task
metadata:
name: hello
spec:
steps:
- name: say-hello
image: ubuntu
command:
- echo
args: ["Hello World"]
```
Here, we're defining a 'Task' that simply prints 'Hello World' using an Ubuntu image. Each 'Task' in Tekton is defined as a series of steps using container images to execute commands.
Once defined, we apply the 'Task' to our cluster.
```
kubectl apply -f hello-task.yaml
```
And now, using `tkn`, Tekton's command line tool, we'll start it. In the next videos, we will see how the Event Listener works, but today we are focusing on the `tkn` command.
```
tkn task start --showlog hello
```
Great! You should see a 'Hello World' in the output.
Now, we'll build a pipeline that uses this 'Task'. A pipeline is essentially a sequence of 'Tasks' that run in order or in parallel, as defined.
```
apiVersion: tekton.dev/v1beta1
kind: Pipeline
metadata:
name: hello-pipeline
spec:
tasks:
- name: greet
taskRef:
name: hello
```
This pipeline is simple and only includes one 'Task'. However, later on, we will add more 'Tasks' and set their order of execution, dependencies, and parallelism.
Let's apply this pipeline and then start it.
```
kubectl apply -f hello-pipeline.yaml
tkn pipeline start hello-pipeline --showlog
```
But let's move forward. To pass parameters from the pipeline to the tasks, we'll start with this task:
```
apiVersion: tekton.dev/v1beta1
kind: Task
metadata:
name: generate-random-number
spec:
params:
- name: limit
description: The upper limit for random number generation.
default: "100"
type: string
steps:
- name: generate-it
image: alpine:latest
command:
- /bin/ash
args: ['-c', 'echo "Random Number: $(($RANDOM % $(params.limit)))"']
```
As you can see, there is a step that generates a random number using a parameter that, in this case, has 100 as the default value. Now, let's see what the pipeline looks like.
```
apiVersion: tekton.dev/v1beta1
kind: Pipeline
metadata:
name: generate-multiple-numbers
spec:
tasks:
- name: first-random-number
taskRef:
name: generate-random-number
params:
- name: limit
value: "50"
- name: second-random-number
taskRef:
name: generate-random-number
params:
- name: limit
value: "200"
- name: third-random-number
taskRef:
name: generate-random-number
params:
- name: limit
value: "1000"
```
As you can see, in the pipeline, we call the task three times with different parameters. So, if we now execute it using the `tkn` CLI:
```
➜ tekton tkn pipeline start generate-multiple-numbers --showlog
PipelineRun started: generate-multiple-numbers-run-9rrmp
Waiting for logs to be available...
[second-random-number : generate-it] Random Number: 58
[first-random-number : generate-it] Random Number: 2
[third-random-number : generate-it] Random Number: 172
```
And that's it! Now you have a solid foundation to explore more of what Tekton can offer. Until next time!

1,896,896 | Thinking Outside the Code: Develop Creative Thinking Ability in Software Engineering | In this digital era, creative thinking is a crucial skill, especially in fields like software... | 0 | 2024-06-22T11:06:41 | https://dev.to/kdgerona/thinking-outside-the-code-develop-creative-thinking-ability-in-software-engineering-bop | softwareengineering, creativethinking, productivity, development | In this digital era, creative thinking is a crucial skill, especially in fields like software engineering where innovation drives success. Let’s explore what creative thinking is, why it’s important, and how you can develop it.
We first need to understand what is **Creative Thinking.**
Creative thinking involves looking at problems or situations from a fresh perspective that suggests unorthodox solutions. I will give you an example, I know this is already common, but maybe you know this already but this is the most effective way for you to understand.
What if I give you six matchsticks and ask you to create three triangles out of it. You will probably think of constructing two triangles using three matchsticks each which is technically wrong because we need to create three triangles.
If you think out of the box, how about we create a pyramid that will only require us six matchsticks to build it and we now have three triangles in total coming from each side.
Pretty simple right? The idea here is you have the resources the matchsticks, the number of matchsticks, and the shape. With these, you can think of many ways and patterns and all of these already exist you just need to come up with something from those resources. This demonstrates using of available resources in novel ways.
**Why is Creative Thinking Important?**
In today's fast-paced world, especially with the rise of the internet and AI, access to information and resources is unprecedented. As software engineers, our role is to innovate and create valuable products. Success in this industry, whether you're a large company or a startup, often hinges on your ability to think creatively and differentiate your offerings.
We need to be a Creative thinker to be able to generate ideas and solutions that are unique.
One good example is based on what the TikTok founder and CEO - Shou Zi Chew says during one of his interviews about how the TikTok idea started, with this very simple statement.
“How about instead of showing you content about the people you knew, we will show you the content that you like”
Sounds intriguing right? Let us dig deeper into this,
In the past or even today, leading Social media platforms like Facebook, Instagram, and Twitter/X use this so-called “Social Graph” wherein you’ll be able to see content about the people you know which is your “friends”, “friends of friends” or the people you “follow”. If we think about it, that is a smart and successful idea for a social media platform.
Just by thinking out of the box, who would've thought that this would be so effective? TikTok flipped this model, focusing on what users like rather than who they know. This “pattern recognition based on interest signals” has been incredibly effective, keeping users engaged by showing them content they genuinely enjoy and is relevant to them.
They shine because of this unique proposition that they have disrupted the idea of the “Social Graph” with this “Pattern recognition based on your interest signals” pretty simple to understand right?
**How to Practice Creative Thinking**
Even though how complex the idea you want to solve as long as you are being resourceful enough and come up with something unique about it, you are now exercising your Creative thinking ability.
Here are some tips that I applied from my day to day as a Software Engineer, to supercharge our Creative Thinking Skills.
1. **Requirements Gathering**: Understand the problem deeply by asking questions and challenging assumptions.
2. **Become a Generalist Specialist**: Gain broad knowledge and deep expertise to draw inspiration from various fields.
3. **First Principles Thinking**: Break down problems into basic elements and reassemble them in innovative ways.
4. **Ideation**: Brainstorm using techniques like mind mapping and SCAMPER. Seek feedback to refine ideas.
5. **Embrace Constraints**: View limitations as opportunities to focus and find unique solutions.
6. **Experiment and Prototype**: Test your ideas, build prototypes, and iterate based on feedback.
7. **Stay Curious**: Continuously learn and explore new interests to fuel creativity.
8. **Collaborate**: Engage with people from diverse backgrounds to spark new ideas.
9. **Reflect and Iterate**: Reflect on your experiences to identify what works and improve future efforts.
10. **Practice Mindfulness**: Use relaxation techniques or any activities that enables you to clear your mind and inspire creativity.
11. **Challenge the Status Quo**: Question conventional wisdom and consider better approaches.
12. **Use Visual Tools**: Sketch, diagram, and use flowcharts to visualize problems and solutions.
Incorporate these practices to enhance your creative thinking and develop innovative solutions.
**Conclusion**
It doesn’t mean that if something is proven and is effective you must cling to it. If you want to revolutionize, you must learn to see things in a different way and from all angles.
If you still think AI could replace you, then you are not good enough.
Remember, while AI can augment our abilities, it cannot replace truly creative and innovative thinking. Use AI and other tools as resources to inspire and enhance your creativity, but always strive to bring a unique perspective to your work.

In this article, we will walk through the process of setting up a search page that leverages MongoDB and Elasticsearch to search across multiple referenced collections. This approach is particularly useful when dealing with complex data relationships and needing powerful search capabilities.
## Prerequisites
- **MongoDB**: Installed on your server or using a managed service like MongoDB Atlas.
- **Elasticsearch**: Installed on your server or using a managed service like Elastic Cloud.
- **Node.js**: For backend implementation.
- **Logstash**: To sync data from MongoDB to Elasticsearch.
To effectively utilize Elasticsearch's powerful search capabilities, it's crucial to transform and synchronize data from MongoDB into a format suitable for indexing. This involves flattening nested data structures and ensuring that only relevant, indexable data is included. In this section, we'll cover the process of data exchange, transformation, and synchronization using Logstash.
### Understanding Data Exchange
#### Data Extraction
1. **MongoDB Source Configuration**: Logstash can be configured to extract data directly from MongoDB. This involves setting up a connection to your MongoDB instance and specifying the collections to be monitored.
#### Data Transformation
2. **Flattening Data**: MongoDB collections often contain nested documents and references to other collections. To make this data indexable in Elasticsearch, we need to flatten these nested structures. Flattening involves merging related data from different collections into a single, cohesive document.
3. **Example**: Suppose we have the following collections:
- `users`: Contains user information.
- `posts`: Contains posts made by users, with each post referencing a user by `user_id`.
We need to transform these collections into a single document structure containing both post and user information.
### Example Configuration with Logstash
#### Logstash Input Configuration
Logstash can be configured to read from MongoDB using the `mongodb` input plugin. Here's an example configuration:
```plaintext
input {
mongodb {
uri => 'mongodb://localhost:27017/mydatabase'
placeholder_db_dir => '/opt/logstash-mongodb/'
placeholder_db_name => 'logstash_sqlite.db'
collection => 'posts'
batch_size => 5000
}
}
```
- `uri`: Connection string for MongoDB.
- `placeholder_db_dir`: Directory to store state information.
- `placeholder_db_name`: Name of the SQLite database file to store state information.
- `collection`: Name of the MongoDB collection to monitor.
- `batch_size`: Number of documents to process in each batch.
#### Logstash Filter Configuration
To flatten the data and enrich posts with user information, we use the `aggregate` filter plugin:
```plaintext
filter {
aggregate {
task_id => "%{user_id}"
code => "
map['user'] ||= {}
event.to_hash.each { |k, v| map['user'][k] = v }
"
push_previous_map_as_event => true
timeout => 3
}
}
```
- `task_id`: A unique identifier for aggregating related data, in this case, `user_id`.
- `code`: The script to enrich and flatten data.
- `push_previous_map_as_event`: Ensures the aggregated data is pushed as a single event.
- `timeout`: Time to wait before pushing the event.
#### Logstash Output Configuration
Finally, configure the output to send the transformed data to Elasticsearch:
```plaintext
output {
elasticsearch {
hosts => ["localhost:9200"]
index => "posts_with_users"
}
}
```
- `hosts`: Elasticsearch server address.
- `index`: Name of the Elasticsearch index to store the data.
### Keeping Data Updated
#### Real-time Synchronization
1. **Change Data Capture**: Utilize MongoDB Change Streams to capture real-time changes in the MongoDB collections. This ensures that any updates, insertions, or deletions in MongoDB are reflected in Elasticsearch.
2. **Logstash Configuration**: Logstash, when configured with the appropriate input plugins, can continuously monitor MongoDB collections for changes and apply them to Elasticsearch.
#### Indexing Only Relevant Data
1. **Selective Indexing**: Focus on indexing only the fields that are relevant for search queries. This reduces the index size and improves search performance.
2. **Example**: If you are only interested in searching posts by content and user details, configure Logstash to only include `post_content`, `user.name`, and `user.email` in the events sent to Elasticsearch.
### Example Logstash Pipeline
Here is a complete example of a Logstash pipeline that extracts, transforms, and loads data from MongoDB to Elasticsearch:
```plaintext
input {
mongodb {
uri => 'mongodb://localhost:27017/mydatabase'
placeholder_db_dir => '/opt/logstash-mongodb/'
placeholder_db_name => 'logstash_sqlite.db'
collection => 'posts'
batch_size => 5000
}
}
filter {
aggregate {
task_id => "%{user_id}"
code => "
map['user'] ||= {}
event.to_hash.each { |k, v| map['user'][k] = v }
"
push_previous_map_as_event => true
timeout => 3
}
# Select only relevant fields
mutate {
remove_field => ["_id", "user_id"]
}
}
output {
elasticsearch {
hosts => ["localhost:9200"]
index =>
## Step 1: Set Up MongoDB and Elasticsearch
### MongoDB Installation
Follow the [MongoDB installation guide](https://docs.mongodb.com/manual/installation/) for your operating system. Alternatively, you can use a managed service like MongoDB Atlas.
### Elasticsearch Installation
Follow the [Elasticsearch installation guide](https://www.elastic.co/guide/en/elasticsearch/reference/current/install-elasticsearch.html) for your operating system. Alternatively, you can use a managed service like Elastic Cloud.
## Step 2: Data Modeling and Indexing
### Identify Collections and Relationships
Assume we have two collections:
- `users`: Contains user information.
- `posts`: Contains posts made by users, with each post referencing a user.
### Flatten Data for Elasticsearch
Elasticsearch works best with denormalized (flattened) data. This means we need to create a single document structure that includes fields from both `users` and `posts`.
## Step 3: Sync Data from MongoDB to Elasticsearch
### Use a Data Sync Tool
To keep your Elasticsearch index updated with data from MongoDB, you can use tools like Logstash, Mongo-Connector, or custom scripts using MongoDB Change Streams.
### Example with Logstash
#### Install Logstash
Follow the [Logstash installation guide](https://www.elastic.co/guide/en/logstash/current/installing-logstash.html) for your operating system.
#### Create a Logstash Configuration File
Here’s an example configuration that denormalizes data from `users` and `posts` collections into a single index:
```plaintext
input {
mongodb {
uri => 'mongodb://localhost:27017/mydatabase'
placeholder_db_dir => '/opt/logstash-mongodb/'
placeholder_db_name => 'logstash_sqlite.db'
collection => 'posts'
batch_size => 5000
}
}
filter {
# Enrich posts with user data
aggregate {
task_id => "%{user_id}"
code => "
map['user'] ||= {}
event.to_hash.each { |k, v| map['user'][k] = v }
"
push_previous_map_as_event => true
timeout => 3
}
}
output {
elasticsearch {
hosts => ["localhost:9200"]
index => "posts_with_users"
}
}
```
#### Run Logstash
Start Logstash with your configuration file.
```sh
bin/logstash -f logstash.conf
```
## Step 4: Index Data in Elasticsearch
Ensure that your data is indexed correctly in Elasticsearch. You can verify this by querying the Elasticsearch index:
```sh
curl -X GET "localhost:9200/posts_with_users/_search?pretty"
```
## Step 5: Create the Search Page
### Backend Setup
#### Choose a Backend Framework
We will use Node.js for this example.
#### Install Elasticsearch Client
Install the Elasticsearch client library for Node.js:
```sh
npm install @elastic/elasticsearch
```
#### Example Code
Create a file named `app.js` and add the following code:
```javascript
const { Client } = require('@elastic/elasticsearch');
const express = require('express');
const app = express();
const client = new Client({ node: 'http://localhost:9200' });
async function search(query) {
const { body } = await client.search({
index: 'posts_with_users',
body: {
query: {
multi_match: {
query: query,
fields: ['post_content', 'user.name', 'user.email']
}
}
}
});
return body.hits.hits;
}
app.get('/search', async (req, res) => {
const query = req.query.q;
const results = await search(query);
res.json(results);
});
app.listen(3000, () => {
console.log('Server is running on port 3000');
});
```
#### Run the Server
Start your Node.js server:
```sh
node app.js
```

This complexity has begged the need for the unparalleled visibility that observability promises.
Observability provides a comprehensive view of your system, allowing you to identify issues before they escalate. Tools like Eyer play a crucial role in achieving observability. Eyer helps gather and analyze system data, revealing anomalies, affected nodes, and potential future problems. With this insight, you can quickly pinpoint issues using Eyer, leading to less downtime and a smoother user experience.
However, the raw data from Eyer might be difficult for non-technical individuals or teams to understand. This is where [Grafana](https://grafana.com/) comes in. As a powerful visualization tool, Grafana transforms this data into clear and insightful dashboards, making it accessible to everyone who needs it.
This article explores Eyer, its importance in modern observability discussions, and the added value of integrating it with Grafana.
## Understanding Eyer and its capabilities
Eyer is an AI-powered observability tool that provides insights into your Boomi integrations. [Boomi](http://boomi.com/) has become an integration superpower, uniting diverse applications and data sources with its simple and intuitive drag-and-drop design. With Eyer, you can take that impeccable user experience to the next level.
By [installing and using the Eyer connector](https://customer.support.eyer.ai/servicedesk/customer/portal/1/article/30015491), you can collect data from your Boomi integrations, send it to the Eyer machine learning pipeline, and gain insights into what's wrong with your Boomi process.
The machine learning pipeline learns the user Boomi Atom’s behavior and establishes what normal behavior or baselines are for your Atom. So, any significant and prolonged deviations from the normal behavior are flagged.
For example, if your Boomi Atom is using more memory than normal or CPU utilization is higher than usual, the Eyer connector will send you a JSON alert. You can choose to receive this alert conveniently via email or even as a file saved directly on your host machine, thanks to the flexibility of Boomi's connectors.
JSON format alerts are advantageous for many reasons: they are structured, human-readable, lightweight, language-agnostic, and can be easily integrated into various systems for automated processing and response. However, while JSON alerts do not have inherent visualization capabilities, tools like Grafana lend them the ability to visualize data over time.
## Grafana: The solution to all your visualization problems
[Grafana](https://grafana.com/) is an open-source analytics and interactive visualization web application tool used to monitor application performance. This section explores how Grafana allows Eyer users to query, visualize, and understand their JSON alerts.
### Benefits of the Grafana integration with Eyer

**Historical analysis**: Another powerful feature of Grafana is its ability to store and visualize historical alert data. Imagine trying to understand a month's worth of system activity by manually reviewing individual JSON alerts; this gets tiring quickly. Grafana offers a much better solution. By aggregating all the data for a specific metric into a single graph, you can easily see trends over days, weeks, or months. This historical view allows you to identify potential issues, forecast future resource needs, and gain insights into long-term performance patterns.
**Collaboration and sharing**: Grafana makes it easy to share dashboards and visualizations with team members. That way, more people can watch and understand what's happening in your systems. These shared insights make it easier for teams to work effectively to address and resolve issues.
**Open-source, extensible**: As an open-source tool, Grafana is free to use and allows users to access and modify the source code, enabling customization to meet specific needs. Its extensibility is one of its core strengths, with a vast ecosystem of plugins available that extend its functionality, including integrations with a wide range of data sources, custom visualizations, and alerting mechanisms. This flexibility makes Grafana adaptable to various use cases and industries.
**Large community support:** Grafana benefits from a large and active community of users and developers. This community support is invaluable, providing a wealth of shared knowledge, tutorials, forums, and plugins. The collaborative nature of the community ensures continuous improvements and updates, keeping Grafana at the forefront of monitoring and visualization tools. This robust support network also means that users can easily find help and resources to solve problems and optimize their platform use.
**Integrating Eyer with Grafana:** In addition to being easy to use, one of the things that makes Eyer stand out is its clear documentation.

1,896,884 | CSR ve SSR | Client-side rendering (CSR) ve server-side rendering (SSR), web sayfalarının nasıl oluşturulacağına... | 0 | 2024-06-22T10:56:13 | https://dev.to/mustafacam/csr-and-ssr-2ohj | Client-side rendering (CSR) ve server-side rendering (SSR), web sayfalarının nasıl oluşturulacağına ve kullanıcıya nasıl sunulacağına dair iki farklı yaklaşımdır. Her iki yöntem de farklı avantajlara ve dezavantajlara sahiptir.
### Client-Side Rendering (CSR)
**Tanım:**
- CSR, web sayfasının içeriğinin kullanıcı tarayıcısında oluşturulmasını ifade eder. Başlangıçta tarayıcıya minimal bir HTML gönderilir ve JavaScript ile sayfanın geri kalanı dinamik olarak yüklenir.
**Nasıl Çalışır:**
1. Kullanıcı bir sayfa talebinde bulunur.
2. Sunucu, temel HTML ve JavaScript dosyalarını kullanıcıya gönderir.
3. Tarayıcı bu dosyaları indirir ve JavaScript kodunu çalıştırarak sayfanın içeriğini oluşturur.
4. Sayfanın geri kalanı, gerekli olduğu anda (lazy loading veya AJAX istekleri ile) dinamik olarak yüklenir.
**Avantajları:**
- **Kullanıcı Etkileşimi:** Kullanıcı ile hızlı ve dinamik etkileşim sağlar.
- **Gelişmiş Kullanıcı Deneyimi:** SPA (Single Page Application) gibi uygulamalarda daha iyi kullanıcı deneyimi sunar.
- **Azaltılmış Sunucu Yükü:** Sunucunun yükü azalır çünkü sayfanın büyük bir kısmı istemci tarafından işlenir.
**Dezavantajları:**
- **SEO Zorlukları:** Arama motorları JavaScript ile oluşturulan içeriği her zaman düzgün bir şekilde tarayamayabilir.
- **Başlangıç Yükleme Süresi:** İlk yükleme süresi daha uzun olabilir çünkü tarayıcı gerekli tüm JavaScript dosyalarını indirip çalıştırmak zorundadır.
- **Düşük Performanslı Cihazlar:** JavaScript'in fazla kullanımı düşük performanslı cihazlarda yavaşlamalara neden olabilir.
### Server-Side Rendering (SSR)
**Tanım:**
- SSR, web sayfasının içeriğinin sunucuda oluşturulup kullanıcının tarayıcısına tam olarak render edilmiş HTML olarak gönderilmesini ifade eder.
**Nasıl Çalışır:**
1. Kullanıcı bir sayfa talebinde bulunur.
2. Sunucu, kullanıcının talebine göre HTML sayfasını oluşturur.
3. Oluşturulan HTML sayfası kullanıcıya gönderilir ve tarayıcı bu sayfayı doğrudan görüntüler.
**Avantajları:**
- **SEO:** Sayfa içeriği sunucuda oluşturulduğu için arama motorları içeriği daha iyi tarayabilir ve dizine ekleyebilir.
- **Hızlı İlk Yükleme:** İlk yükleme süresi daha hızlı olabilir çünkü tarayıcı, tam olarak oluşturulmuş HTML'yi hemen gösterebilir.
- **Daha İyi Performans:** Daha az JavaScript kodu çalıştırıldığı için düşük performanslı cihazlarda daha iyi performans gösterir.
**Dezavantajları:**
- **Sunucu Yükü:** Sunucu, her sayfa talebi için HTML oluşturmak zorunda olduğu için yükü artabilir.
- **Dinamik Etkileşimler:** Kullanıcı etkileşimlerine anında cevap vermek daha zor olabilir ve ek AJAX istekleri gerektirebilir.
- **Geliştirme Karmaşıklığı:** Karmaşık uygulamalar için geliştirme ve bakım zor olabilir çünkü hem sunucu tarafında hem de istemci tarafında kod yazmak gerekebilir.
### Hibrit Yaklaşımlar
Bazı modern web uygulamaları, CSR ve SSR'nin avantajlarını birleştiren hibrit yaklaşımlar kullanır. Örneğin, Next.js gibi frameworkler sunucu tarafında başlangıç render işlemini yapar ve daha sonra istemci tarafında dinamik güncellemeler yapar. Bu, hem hızlı ilk yükleme süreleri hem de dinamik kullanıcı etkileşimleri sağlar.
Her iki yöntemin de kendi kullanım durumlarına göre avantajları ve dezavantajları vardır. Seçim yaparken projenizin ihtiyaçlarını ve hedeflerinizi göz önünde bulundurmanız önemlidir. | mustafacam | |

Seemingly, contemporary technologies have made it possible for architects and builders to include other safety measures in these indoor designs. According to the experts of [[STYLARC](www.stylarc.com)], such improvement can enhance the physical security of indoor spaces and reduce the possibility of an accident occurring.
**Monitoring Systems**
This is one of the aspects that have witnessed a major technological advancement, according to STYLARC's expert service, especially in the installation of monitoring systems. These include features like:
· Smart security cameras – Security cameras with HD features that are connected to the internet make it possible for one to monitor a home or office in real-time. In case of any suspicious activity, the said area may be monitored, and alerts can be made to the homeowners /security personnel.
· Automated entry alerts - This is a motion sensor placed near the exit and entry points that send alerts through either an SMS or an application when someone enters the premises. This way, when an intruder gets in, action is taken immediately.
· Smoke and carbon monoxide detectors – These alarms produce loud sounds and notifications when the concentration of gases or smoke in a specific region becomes hazardous. The facility enables residents to conveniently exit or fight fires in an emergency.
Strategic Lighting
Proper lighting design also boosts indoor safety significantly through features.
· Emergency lighting systems – Lights with a battery backup that turns on automatically whenever there is a power failure to provide for safe egress.
· Automatic lamps – Lamps that are switched on by motion-detecting sensors in cases where anybody approaches entry or exit doors, especially during the night. Enhances visibility and security.
· Smart lighting – WiFi connectable LED smart bulbs for the remote control of room lights. It may be programmed to turn on/off at some specific times in order to simulate the presence of people when one is out.
Slip-Resistant Flooring
Flooring, which entails using materials that enhance the possibility of a slip, generates a lower probability of slip and fall accidents. Some options include:
· The tiles are specially designed with an uneven surface and grout line junctions that create a firm holding on feet. Most beneficial in washrooms as they are able to prevent water from infiltrating into other parts of the building.
· Rubber mats are used in areas that may contain water or any signs of dampness, such as washrooms. It does not slide even in wet conditions since it has a high-friction surface.
· Vinyl flooring with particles enhances grip on the floor and ensures that one does not slip when walking or running. Less maintenance than tile, making it more suitable for areas with high levels of foot traffic.
**Conclusion**
**[STYLARC ](www.instagram.com/stylarc)**suggests that the application of smart systems such as modern surveillance systems, proper lighting, and anti-slip flooring can significantly reduce the level of danger inside structures. Advances in technology make it possible for manufacturers to incorporate such protective features in products in a convenient and cost-effective manner. These indoor safety improvements are more reassuring and help avoid misfortunes or property loss, too, in case they happen when the other features are considered less important. In this regard, with careful coordination, technology will surely assist in transforming living and work spaces into secure environments. | stylarc |

1. If the website is quite big like an e-comm platform there are 1000's of server pages which might take a lot of time to build.
2. Build time -> proportional to no. of statically generated pages.
3. For a platform like e-comm 10% of data (statically pre-rendered) whereas other 90% fetched afterwards may seem like an option.
4. Still, the most evident problem is of _stale _ data.
5. If we change any data, the pre-rendered pages will read the same old data.

1,896,872 | Mastering smart contract deployment with MultiversX JavaScript SDK | In the third article and video, I would like to focus on the MultiversX JavaScript/TypeScript SDK in... | 27,816 | 2024-06-22T10:40:33 | https://www.julian.io/articles/multiversx-js-sdk-sc-deployment.html | javascript, web3, blockchain, multiversx | In the third article and video, I would like to focus on the MultiversX JavaScript/TypeScript SDK in the context of smart contract deployments. As in previous articles, we will go through the whole script step by step, explaining each SDK tool.
First, let's see the whole script and go through each important part:
```javascript
import { promises } from "node:fs";
import {
TransactionComputer,
TransactionsFactoryConfig,
SmartContractTransactionsFactory,
Code,
Address,
TransactionWatcher,
SmartContractTransactionsOutcomeParser,
TransactionsConverter,
} from "@multiversx/sdk-core";
import {
syncAndGetAccount,
senderAddress,
getSigner,
apiNetworkProvider,
} from "./setup.js";
const deploySmartContract = async () => {
const user = await syncAndGetAccount();
const computer = new TransactionComputer();
const signer = await getSigner();
// Load smart contract code
// For source code check: https://github.com/xdevguild/piggy-bank-sc/tree/master
const codeBuffer = await promises.readFile("./piggybank.wasm");
const code = Code.fromBuffer(codeBuffer);
// Load ABI file (not required for now, but will be useful when interacting with the SC)
// Although it would be helpful if we had initial arguments to pass
const abiFile = await promises.readFile("./piggybank.abi.json", "UTF-8");
// Prepare transfer transactions factory
const factoryConfig = new TransactionsFactoryConfig({ chainID: "D" });
let scFactory = new SmartContractTransactionsFactory({
config: factoryConfig,
abi: abiFile,
});
// Prepare deploy transaction
const deployTransaction = scFactory.createTransactionForDeploy({
sender: new Address(senderAddress),
bytecode: code.valueOf(),
gasLimit: 10000000n,
arguments: [], // Pass arguments for init function on SC, we don't have any on this smart contract
// Below ones are optional with default values
nativeTransferAmount: 0, // Sometimes you need to send EGLD to the init function on SC
isUpgradeable: true, // You will be able to upgrade the contract
isReadable: false, // You will be able to read its state through another contract
isPayable: false, // You will be able to send funds to it
isPayableBySmartContract: false, // Only smart contract can send funds to it
});
// Increase the nonce
deployTransaction.nonce = user.getNonceThenIncrement();
// Serialize the transaction for signing
const serializedDeployTransaction =
computer.computeBytesForSigning(deployTransaction);
// Sign the transaction with our signer
deployTransaction.signature = await signer.sign(serializedDeployTransaction);
// Broadcast the transaction
const txHash = await apiNetworkProvider.sendTransaction(deployTransaction);
// You can compute the smart contract address before broadcasting the transaction
// https://docs.multiversx.com/sdk-and-tools/sdk-js/sdk-js-cookbook-v13#computing-the-contract-address
// But let's see how to get it from the network after deployment
console.log("Pending...");
// Get the transaction on the network, we need to wait for the results here. We use TransactionWatcher for that
const transactionOnNetwork = await new TransactionWatcher(
apiNetworkProvider
).awaitCompleted(txHash);
// Now let's parse the results with TransactionsConverter and SmartContractTransactionsOutcomeParser
const converter = new TransactionsConverter();
const parser = new SmartContractTransactionsOutcomeParser();
const transactionOutcome =
converter.transactionOnNetworkToOutcome(transactionOnNetwork);
const parsedOutcome = parser.parseDeploy({ transactionOutcome });
console.log(
`Smart Contract deployed. Here it is:\nhttps://devnet-explorer.multiversx.com/accounts/${parsedOutcome.contracts[0].address}\n\nCheck the transaction in the Explorer:\nhttps://devnet-explorer.multiversx.com/transactions/${txHash}`
);
};
deploySmartContract();
```
As you probably have already noticed, the structure is very similar to that of the previous scripts. We use the same helpers from the setup.js file, so I won't focus on them here. Check the first article for more info about them. The preparation to broadcast is also similar. There is one new thing, but we will get to it.
What is important in this demo is that I need a smart contract. This is why I included the WASM source code and the ABI file in the repository. The smart contract is a simple piggy bank functionality, and you can find the source code in the xDevGuild GitHub repository: Piggy Bank Smart Contract. The functionality is simple but not important in this context. Let's focus on the deployment.
After downloading the source code (in the same place as the script file), we need to read and include it in our script. We can do this with Node file system utilities. We also need to use Code from MultiversX SDK to prepare the proper format.
```javascript
// Load smart contract code
// For source code check: https://github.com/xdevguild/piggy-bank-sc/tree/master
const codeBuffer = await promises.readFile("./piggybank.wasm");
const code = Code.fromBuffer(codeBuffer);
// Load ABI file (not required for now, but will be useful when interacting with the SC)
// Although it would be helpful if we had initial arguments to pass
const abiFile = await promises.readFile("./piggybank.abi.json", "UTF-8");
```
Next, we need to prepare the core setup. The configuration uses TransactionsFactoryConfig (similar to previous ones) and the SmartContractTransactionsFactory. The factory is similar to others but specific to smart contract operations. After that, we can use the createTransactionForDeploy from our factory and configure the deployment transaction. Let's stop for a moment, but first, let's see that part of the code to clarify it.
```javascript
// Prepare transfer transactions factory
const factoryConfig = new TransactionsFactoryConfig({ chainID: "D" });
let scFactory = new SmartContractTransactionsFactory({
config: factoryConfig,
abi: abiFile,
});
// Prepare deploy transaction
const deployTransaction = scFactory.createTransactionForDeploy({
sender: new Address(senderAddress),
bytecode: code.valueOf(),
gasLimit: 10000000n,
arguments: [], // Pass arguments for init function on SC, we don't have any on this smart contract
// Below ones are optional with default values
nativeTransferAmount: 0, // Sometimes you need to send EGLD to the init function on SC
isUpgradeable: true, // You will be able to upgrade the contract
isReadable: false, // You will be able to read its state through another contract
isPayable: false, // You will be able to send funds to it
isPayableBySmartContract: false, // Only smart contract can send funds to it
});
```
When configuring the deployment transaction, you have a couple of options. Of course, the most important is to provide the binary source code of the smart contract, but you can also do a couple of other things.
Each smart contract has an init function, which is triggered when the contract is deployed. This function could be useful in many ways, mostly for initial storage configuration. Of course, you can pass arguments to it. This is why we have the arguments array when configuring the transaction. In our case, the Piggy Bank doesn't require initial arguments, but you would need that in many cases. You can pass plain data to the array when using ABI. It should be handled properly, but you can also use data helpers from MultiversX SDK. You'll find them, for example, here: [mx-sdk-js-core typesystem](https://github.com/multiversx/mx-sdk-js-core/tree/main/src/smartcontracts/typesystem). So, in short words, you can, for example, import U32Value from MultiversX SDK and then use it like: arguments: [new U32Value(123)]. But don't worry about it when you have the ABI. Then it should also work like arguments: [123]. Of course, the order of arguments is important.
Okay, what next? Sometimes, you need to provide a payment for the init function. For example, your smart contract could have logic that requires locking some EGLD amount on initialization. It is why we have the nativeTransferAmount. You can pass it there.
We also have some 'flags' that will help to configure our smart contract and its future behavior. You can define your contract as upgradable with isUpgradable. You can define if your contract can be payable by anyone by isPayable. You can limit the payable functionality only to allow a smart contract with isPayableBySmartContract. Finally, you can define if your smart contract can be readable by other smart contracts using isReadable.
Okay, let's move on. After we configure our deployment transaction, we need to prepare some standard steps, as with all transactions. So we need to increment the nonce, serialize the transaction, sign it, and broadcast it.
```javascript
// Increase the nonce
deployTransaction.nonce = user.getNonceThenIncrement();
// Serialize the transaction for signing
const serializedDeployTransaction =
computer.computeBytesForSigning(deployTransaction);
// Sign the transaction with out signer
deployTransaction.signature = await signer.sign(serializedDeployTransaction);
// Broadcast the transaction
const txHash = await apiNetworkProvider.sendTransaction(deployTransaction);
```
In this case, we need to get the smart contract address. We can compute it before we send the transaction, but we want to be sure that the deployment transaction went through and that the smart contract was deployed. We will get the address from the transaction outcome. We can do this by using a couple of tools. These operations are more general, not only in the context of smart contracts, so you can use them for any transaction.
```javascript
// Get the transaction on the network, we need to wait for the results here. We use TransactionWatcher for that
const transactionOnNetwork = await new TransactionWatcher(
apiNetworkProvider
).awaitCompleted(txHash);
// Now let's parse the results with TransactionsConverter and SmartContractTransactionsOutcomeParser
const converter = new TransactionsConverter();
const parser = new SmartContractTransactionsOutcomeParser();
const transactionOutcome =
converter.transactionOnNetworkToOutcome(transactionOnNetwork);
const parsedOutcome = parser.parseDeploy({ transactionOutcome });
console.log(
`Smart Contract deployed. Here it is:\nhttps://devnet-explorer.multiversx.com/accounts/${parsedOutcome.contracts[0].address}\n\nCheck the transaction in the Explorer:\nhttps://devnet-explorer.multiversx.com/transactions/${txHash}`
);
```
The TransactionWatcher will wait and get the transaction results on the chain. We must also prepare a converter and parser using tools from the MultiversX SDK. With that, we can pass the transactionOnNetwork and parse the outcome to get the address.
The parsedOutome in this case has such a structure:
```javascript
{
returnCode: 'ok',
returnMessage: 'ok',
contracts: [
{
address: 'erd1qqqqqq...',
ownerAddress: 'erd1...',
codeHash: <Buffer ...>
}
]
}
```
**Summary**
That's it. We have a full deployment script. The smart contract has been deployed to the devnet chain and is ready to work with. I'll put together an article and video that show how to interact with such a smart contract.
Follow me on X ([@theJulianIo](https://x.com/theJulianIo)) and YouTube ([@julian_io](https://www.youtube.com/channel/UCaj-mgcY9CWbLdZsC5Gt00g)) or [GitHub](https://github.com/juliancwirko) for more MultiversX magic.
Please check the tools I maintain: the [Elven Family](https://www.elven.family) and [Buildo.dev](https://www.buildo.dev). With Buildo, you can do a lot of management operations using a nice web UI. You can [issue fungible tokens](https://www.buildo.dev/fungible-tokens/issue), [non-fungible tokens](https://www.buildo.dev/non-fungible-tokens/issue). You can also do other operations, like [multi-transfers](https://www.buildo.dev/general-operations/multi-transfer) or [claiming developer rewards](https://www.buildo.dev/general-operations/claim-developer-rewards). There is much more.

This not only helps in finding talented individuals but also allows the company to build a strong network within the local industry. Additionally, conducting thorough research on the cultural norms and values of the target country can help tailor recruitment strategies to attract and retain top talent.
Understanding the Environment
The electronics sector is very competitive and driven by new ideas, so hiring skilled workers is very important. For foreign companies starting in a new market, it's important to know the local job culture, legal environment, and what potential employees expect.

By aligning their strategies with the expectations of potential employees, these companies can attract and retain top talent in the electronics sector.
Market Research and Adapting to Culture
Good recruitment starts with deep market research. New foreign companies must understand the job market, including usual salaries, benefits, and work conditions. Also, adapting to the cultural differences of the host country can greatly improve how well recruitment efforts work. This includes respecting local customs, ways of talking, and professional expectations.
By conducting market research, companies can gain valuable insights into the specific needs and preferences of the local workforce. This knowledge allows them to tailor their recruitment strategies to attract and retain top talent effectively. Additionally, understanding and adapting to the cultural nuances of the host country can foster a positive work environment and enhance employee satisfaction, ultimately contributing to the success of the company's recruitment efforts.
Following Laws and Legal Issues
Following local employment laws is a must. Foreign companies must understand visa rules for foreign workers, labour laws, and policies for equal employment opportunities. Not following these can lead to legal problems and hurt the company’s image, affecting its ability to hire the best workers.
Additionally, it is crucial for foreign companies to familiarise themselves with the local regulations regarding employee benefits, such as minimum wage requirements and mandatory leave policies. Failure to comply with these laws can result in penalties and damage the company's reputation, making it less attractive to potential employees. Therefore, staying updated on all legal obligations is essential for maintaining a positive and compliant work environment.
Making Recruitment Strategies
After understanding the local environment, a foreign company can make effective recruitment strategies. These strategies should be new, flexible, and match the company's main goals and values.
It is important for the company to consider the cultural norms and practices of the local workforce when designing their recruitment strategies. Additionally, conducting thorough market research can help identify any specific skills or qualifications that are in high demand in the local job market, allowing the company to tailor their recruitment efforts accordingly.
Building a Strong Company Image
It's important to create a strong image as an employer. This involves showing off the company’s culture, values, and benefits to make it a desirable place to work. This can be hard for new companies in the electronics sector, where established brands might already be well-known.

By emphasising their unique selling points and showcasing a dynamic and forward-thinking work environment, these companies can establish themselves as competitive players in the electronics sector.
Working with Local Schools

These additional incentives not only help companies attract top talent but also contribute to employee satisfaction and loyalty. By providing a comprehensive package of pay and benefits, foreign companies can create a positive work environment that fosters productivity and long-term commitment from their employees.
Using Technology in Hiring
Using technology in hiring can give foreign companies an advantage. This includes using AI for finding talent, social media for building the company's image, and virtual reality for job previews. These technologies can make the hiring process easier and attract people who are good with technology in the electronics sector.

1,896,858 | How to Dynamically Render HTML Tags in Angular 16.2+ | At Builder.io, we use Mitosis to generate multi-framework SDKs, enabling us to maintain one codebase... | 0 | 2024-06-22T10:17:16 | https://dev.to/builderio/how-to-dynamically-render-html-tags-in-angular-162-42b7 | webdev, angular, javascript, tutorial | At Builder.io, we use [Mitosis](https://mitosis.builder.io/) to generate multi-framework SDKs, enabling us to maintain one codebase that outputs code for React, Preact, Solid, Vue, Angular, Svelte, and more.. Some frameworks leverage normal JSX syntax like React but not all frameworks use JSX right? In React, achieving dynamic HTML generation is straightforward--simply use state to update the tag directly. However, with Angular, it wasn't possile until the version 16.2, which introduced the `ngComponentOutlet` directive.
## Dynamic HTML Generation in React
Here’s an example of dynamic HTML generation in React:
```jsx
function App() {
const [Tag, setTag] = useState("div");
const updateTag = (e) => {
setTag(e.target.value);
};
return (
<>
<select onChange={updateTag}>
<option value="div">div</option>
<option value="span">span</option>
<option value="p">p</option>
<option value="a">a</option>
<option value="h1">h1</option>
</select>
<Tag>Inside {Tag}</Tag>
</>
);
}
```
In this example, the `Tag` state updates based on the selected value, rendering the corresponding HTML tag dynamically. We wanted to replicate this functionality in Angular. Is it possible? Yes, with some modifications!
## Dynamic Component Generation in Angular
In Angular, you can achieve dynamic component generation using the `ngComponentOutlet` directive. Here’s how:
### Step 1: Define Dynamic Components
First, we create components for each tag we want to generate dynamically (you can automate this using a script):
```tsx
import { Component, ViewChild, ElementRef } from '@angular/core';
@Component({
selector: 'dynamic-div, DynamicDiv',
template: `<div #v><ng-content></ng-content></div>`,
standalone: true,
})
export class DynamicDiv {
@ViewChild('v', { read: ElementRef }) v!: ElementRef;
}
@Component({
selector: 'dynamic-h1, DynamicH1',
template: `<h1 #v><ng-content></ng-content></h1>`,
standalone: true,
})
export class DynamicH1 {
@ViewChild('v', { read: ElementRef }) v!: ElementRef;
}
@Component({
selector: 'dynamic-a, DynamicA',
template: `<a #v href=""><ng-content></ng-content></a>`,
standalone: true,
})
export class DynamicA {
@ViewChild('v', { read: ElementRef }) v!: ElementRef;
}
@Component({
selector: 'dynamic-button, DynamicButton',
template: `<button #v><ng-content></ng-content></button>`,
standalone: true,
})
export class DynamicButton {
@ViewChild('v', { read: ElementRef }) v!: ElementRef;
}
```
> Why are there unused refs here you ask? You can extend this functionality to dynamically add attributes or action attributes to any of the elements. A more complete example can be found [here in our Opensource SDKs repository](https://github.com/BuilderIO/builder/blob/main/packages/sdks/overrides/angular/src/components/dynamic-renderer/dynamic-renderer.ts).
### Step 2: Create a Dynamic Renderer Component
Next, we create a `DynamicRenderComponent` that will use the `ngComponentOutlet` directive to render the selected component dynamically:
```tsx
import {
Component,
Input,
ViewChild,
ViewContainerRef,
TemplateRef,
Renderer2,
OnChanges
} from '@angular/core';
import { CommonModule } from '@angular/common';
@Component({
selector: 'dynamic-renderer',
template: `
<ng-template #tagTemplate><ng-content></ng-content></ng-template>
<ng-container
*ngComponentOutlet="Element; content: myContent">
</ng-container>
`,
standalone: true,
imports: [CommonModule]
})
export class DynamicRenderComponent implements OnChanges {
@Input() Tag: any = 'div';
@ViewChild('tagTemplate', { static: true }) tagTemplate!: TemplateRef<any>;
Element: any = DynamicDiv;
myContent: any;
constructor(private vcRef: ViewContainerRef) {}
ngOnChanges() {
switch (this.Tag) {
case 'div':
this.Element = DynamicDiv;
break;
case 'button':
this.Element = DynamicButton;
break;
case 'a':
this.Element = DynamicA;
break;
case 'h1':
this.Element = DynamicH1;
break;
default:
this.Element = DynamicDiv;
break;
}
this.myContent = [
this.vcRef.createEmbeddedView(this.tagTemplate).rootNodes,
];
}
}
```
### Step 3: Create the Main Component
Finally, we create the main component that includes a dropdown to select the desired tag and renders the dynamic component accordingly:
```tsx
import { Component } from '@angular/core';
import { bootstrapApplication } from '@angular/platform-browser';
import { DynamicRenderComponent } from './dynamic-render.component';
@Component({
selector: 'app-root',
template: `
<select (change)="onChange($event)">
<option value="div">div</option>
<option value="button">button</option>
<option value="span">span</option>
<option value="p">p</option>
<option value="a">a</option>
<option value="h1">h1</option>
</select>
<dynamic-renderer [Tag]="Tag">Inside {{ Tag }}</dynamic-renderer>
`,
standalone: true,
imports: [DynamicRenderComponent]
})
export class PlaygroundComponent {
Tag = 'div';
onChange(event: any) {
this.Tag = event.target.value;
}
}
bootstrapApplication(PlaygroundComponent);
```
In this example, the `PlaygroundComponent` handles the tag selection, and the `DynamicRenderComponent` dynamically renders the selected tag. This approach ensures that we can generate dynamic HTML elements in Angular, similar to how it’s done in React.

1,896,849 | Transfer tokens using MultiversX JavaScript SDK | In the second article and video about MultiversX JavaScript/TypeScript SDK, I want to focus on token... | 27,816 | 2024-06-22T10:16:53 | https://www.julian.io/articles/multiversx-js-sdk-transfers.html | blockchain, web3, javascript, multiversx | In the second article and video about MultiversX JavaScript/TypeScript SDK, I want to focus on token transfers. Please check the first one, which presents all the helper tools and setup. I will also use them here. At the end of this article, you'll find the video with a voiceover and a link to the repository.
What I want to cover here:
- How to send native EGLD using transfer methods
- How to send ESDTs using transfer methods
The main focus will be preparing and using transaction factories, in this case, the transfer transaction factory.
**How to send native EGLD using transfer methods**
In the previous video, we also sent the EGLD native tokens using a custom Transaction class, but there is a simpler and cleaner method.
Let's check the code below and then analyze it step by step.
```javascript
import {
TransactionComputer,
Address,
TransactionsFactoryConfig,
TransferTransactionsFactory,
} from "@multiversx/sdk-core";
import {
receiverAddress,
syncAndGetAccount,
senderAddress,
getSigner,
apiNetworkProvider,
} from "./setup.js";
const makeTransfer = async () => {
const user = await syncAndGetAccount();
const computer = new TransactionComputer();
const signer = await getSigner();
// Prepare transfer transactions factory
const factoryConfig = new TransactionsFactoryConfig({ chainID: "D" });
const factory = new TransferTransactionsFactory({ config: factoryConfig });
// Transfer native EGLD token (value transfer, the same as with the simple transaction)
const egldTransaction = factory.createTransactionForNativeTokenTransfer({
sender: new Address(senderAddress),
receiver: new Address(receiverAddress),
// 0.01 EGLD (EGLD has 18 decimal places)
nativeAmount: BigInt("10000000000000000"),
});
egldTransaction.nonce = user.getNonceThenIncrement();
const serializedEgldTransaction =
computer.computeBytesForSigning(egldTransaction);
egldTransaction.signature = await signer.sign(serializedEgldTransaction);
const txHash = await apiNetworkProvider.sendTransaction(egldTransaction);
console.log(
"EGLD sent. Check in the Explorer: ",
`https://devnet-explorer.multiversx.com/transactions/${txHash}`
);
};
makeTransfer();
```
So, the structure is very similar to that of the first article. What is different here is how we build our transaction object. But let's analyze the makeTransfer function starting from the top.
First, we prepare the objects required for all transactions: the user object, the transaction computer for serialization, and the signer.
```javascript
const user = await syncAndGetAccount();
const computer = new TransactionComputer();
const signer = await getSigner();
```
For more information, please check the first article. I won't focus on it much.
Preparing the transfer transaction factory is the central part of this process. You must prepare the config and the factory itself.
```javascript
const factoryConfig = new TransactionsFactoryConfig({ chainID: "D" });
const factory = new TransferTransactionsFactory({ config: factoryConfig });
```
Then, you will prepare the transaction for signing (and later broadcast) by invoking the _createTransactionForNativeTokenTransfer_ method on the previously prepared factory.
```javascript
const egldTransaction = factory.createTransactionForNativeTokenTransfer({
sender: new Address(senderAddress),
receiver: new Address(receiverAddress),
// 0.01 EGLD (EGLD has 18 decimal places)
nativeAmount: BigInt("10000000000000000"),
});
```
You need to pass the receiver and sender. Also, you need to pass nativeAmount, which should be a BigInt, and remember that native EGLD has 18 decimal places. So to send 0.01 EGLD, you need to pass BigInt("10000000000000000"). Of course, there are helpers for that, or you can build one using, for example, the bignumber.js library, but let's keep it simple for now.
Ok this is all. You have prepared the transaction for signing.
The following steps are similar to the first video, the first transaction example. You need to set and increment the nonce, serialize the transaction, sign it, and send it.
```javascript
egldTransaction.nonce = user.getNonceThenIncrement();
const serializedEgldTransaction =
computer.computeBytesForSigning(egldTransaction);
egldTransaction.signature = await signer.sign(serializedEgldTransaction);
const txHash = await apiNetworkProvider.sendTransaction(egldTransaction);
console.log(
"EGLD sent. Check in the Explorer: ",
`https://devnet-explorer.multiversx.com/transactions/${txHash}`
);
```
That's it. You broadcasted the transaction that moved the EGLD value from one wallet to another. Check the video for more details.
**How to send ESDTs using transfer methods**
Now, let's check how we can move ESDT tokens, which are custom tokens that you can issue on the MultiversX blockchain. They can be fungible, semi-fungible, or non-fungible (there are also meta tokens, but let's leave them; they are all similar).
As with the EGLD, let's see the whole code first, and then we will proceed step by step. It will be code from the multi-transfer demo. The video will provide a more detailed walkthrough for a single transfer of each token type, but the code is very similar to this one, so let's use it here.
```javascript
import {
TransactionComputer,
Address,
TransactionsFactoryConfig,
TransferTransactionsFactory,
TokenTransfer,
Token,
} from "@multiversx/sdk-core";
import {
receiverAddress,
syncAndGetAccount,
senderAddress,
getSigner,
apiNetworkProvider,
} from "./setup.js";
const makeTransfer = async () => {
const user = await syncAndGetAccount();
const computer = new TransactionComputer();
const signer = await getSigner();
// Prepare transfer transactions factory
const factoryConfig = new TransactionsFactoryConfig({ chainID: "D" });
const factory = new TransferTransactionsFactory({ config: factoryConfig });
// Transfer native EGLD token (value transfer, the same as with the simple transaction)
const multiTransferTransaction =
factory.createTransactionForESDTTokenTransfer({
sender: new Address(senderAddress),
receiver: new Address(receiverAddress),
tokenTransfers: [
new TokenTransfer({
token: new Token({
identifier: "ELVNFACE-762e9d",
nonce: BigInt("90"),
}),
// Send 1, it is always 1 for NFTs
amount: BigInt("1"), // or 1n
}),
new TokenTransfer({
token: new Token({ identifier: "DEMSFT-00eac9", nonce: BigInt("1") }),
// Send 10
amount: BigInt("10"), // or 10n
}),
new TokenTransfer({
token: new Token({ identifier: "DEMFUNGI-3ec13b" }),
// Send 10, remember about 18 decimal places
amount: BigInt("10000000000000000000"), // or 10000000000000000000n
}),
],
});
multiTransferTransaction.nonce = user.getNonceThenIncrement();
const serializedmultiTransferTransaction = computer.computeBytesForSigning(
multiTransferTransaction
);
multiTransferTransaction.signature = await signer.sign(
serializedmultiTransferTransaction
);
const txHash = await apiNetworkProvider.sendTransaction(
multiTransferTransaction
);
console.log(
"Multiple ESDTs sent. Check in the Explorer: ",
`https://devnet-explorer.multiversx.com/transactions/${txHash}`
);
};
makeTransfer();
```
As you can see, the code looks very similar to the native EGLD transfer, and that's the case. We want to have an excellent developer experience here. What changes here is the method on our transfer factory which is now createTransactionForESDTTokenTransfer.
```javascript
const multiTransferTransaction =
factory.createTransactionForESDTTokenTransfer({
sender: new Address(senderAddress),
receiver: new Address(receiverAddress),
tokenTransfers: [
new TokenTransfer({
token: new Token({
identifier: "ELVNFACE-762e9d",
nonce: BigInt("90"),
}),
// Send 1, it is always 1 for NFTs
amount: BigInt("1"), // or 1n
}),
new TokenTransfer({
token: new Token({ identifier: "DEMSFT-00eac9", nonce: BigInt("1") }),
// Send 10
amount: BigInt("10"), // or 10n
}),
new TokenTransfer({
token: new Token({ identifier: "DEMFUNGI-3ec13b" }),
// Send 10, remember about 18 decimal places
amount: BigInt("10000000000000000000"), // or 10000000000000000000n
}),
],
});
```
We now use the tokenTransfers field instead of nativeAmount. We don't need to move any EGLD value here. In tokenTransfers, you can put different token types where you will define the identifier, amount, and in the case of NFT/SFT/Meta, also proper nonce.
Let's go through all three cases. For non-fungible ESDT, you have:
```javascript
new TokenTransfer({
token: new Token({
identifier: "ELVNFACE-762e9d",
nonce: BigInt("90"),
}),
// Send 1, it is always 1 for NFTs
amount: BigInt("1"), // or 1n
}),
```
The TokenTransfer and Token classes are, of course, imported from MultiversX SDK. The identifier here, ELVNFACE-762e9d, is, in fact, the identifier of the NFT collection. Then, for a particular NFT to send, which is here ELVNFACE-762e9d-5a, you need to pass its nonce, here 5a, which is a decimal hex representation of 90. Don't worry. You'll also find the nonce in the MultiversX Explorer. Check the video for more details. Next we need to pass the amount to send. It will always be 1 for NFTs and should be passed as BigInt.
The situation is very similar for the SFTs. The main difference is that you can pass more than 1 in the amount.
```javascript
new TokenTransfer({
token: new Token({ identifier: "DEMSFT-00eac9", nonce: BigInt("1") }),
// Send 10
amount: BigInt("10"), // or 10n
}),
```
We send 10 of DEMSFT-00eac9-01 where 01 is nonce 1 and the collection is DEMSFT-00eac9.
There is a critical difference between the fungible ESDTs. They can have decimal places, so you need to remember this when transferring. (By the way, remember that also when transferring Meta ESDTs).
```javascript
new TokenTransfer({
token: new Token({ identifier: "DEMFUNGI-3ec13b" }),
// Send 10, remember about 18 decimal places
amount: BigInt("10000000000000000000"), // or 10000000000000000000n
}),
```
We don't need the nonce here. There is no 'collection'. The identifier is our token identifier. And as mentioned you need to remember about the decimal places and pass the value as BigInt.
**Summary**
Here you have it. You learned how to transfer different types of tokens on the MultiversX blockchain using one of the most used programming language and SDK.
