How to Convert Dates in One Group into An Interval
Tags: sql, database, dataengineering, development
Published: 2024-03-28 07:11:22

We have a database table TBLTEST. Below is part of its data:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/syex87sowu6ja5420tg8.png)
The data is ordered by date. We are trying to group rows by the first five columns, convert dates in each group into an interval, and record the ending date of the last record as the infinite date 99991230. Below is the desired result:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/40gphz8lz2mi3a37nz5m.png)
Oracle SQL:

```
SELECT
     code1,
     code2,
     code3,
     rate,
     value,
     min(MONTH) start_dt,
     CASE
          WHEN ROW_NUMBER() OVER(PARTITION BY code1, code2, code3 ORDER BYmax(MONTH) DESC) = 1 THEN 99991230
          ELSE max(MONTH)
     END end_dt
FROM
     (
     SELECT
          t.*,
          ROW_NUMBER() OVER(PARTITION BY code1, code2, code3 ORDER BY MONTH) rn1,
          ROW_NUMBER() OVER(PARTITION BY code1, code2, code3, rate, value ORDERBY MONTH) rn2
     FROM
          TBLTEST t
) t
GROUP BY
     code1,
     code2,
     code3,
     rate,
     value,
     rn1 - rn2
ORDER BY
     start_dt
```
It is rather simple to perform the task in the natural way of thinking. We compare neighboring values between rows on the first five columns, and put the current one and the previous row in the same group when values are same, or create a new group if they are different until the last record is compared. As SQL set is unordered, we need to first invent two columns of indexes manually in an extremely complicated way and then perform grouping according to the relationship between the two columns of indexes. You need to be really smart to come up with the solution.

Yet it is easy to write the code using the open-source esProc SPL:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ywxing56rvyfwmeha0fv.png)
SPL supports ordered sets directly, making it easy to perform grouping when a neighboring value is different.
Microservices & Java Projects: Can Boilerplates Save the Day?
Tags: java, microservices, programming, coding
Published: 2024-03-28 07:08:59

Hey devs, 

Let's talk starting points for new Java projects, especially those venturing into microservices architecture.
We all know the initial setup can be a time-consuming beast –  configuring authentication, security, databases, communication channels – the list goes on!

### Microservices & the Setup Struggle:

Microservices offer amazing benefits for scalability and maintainability, but setting them up from scratch is no walk in the park.
Each service needs its own boilerplate code for these common functionalities, eating into valuable development time.

### Docker & Kubernetes: Power & Complexity:

Containerization with Docker and deployment on Kubernetes are powerful tools for modern Java applications.
However, learning these technologies and crafting deployment configurations adds another layer of complexity to the initial setup.

### Java Boilerplate:

Here's where a well-designed Java boilerplate could be a game-changer. Imagine having a pre-built framework that offers:

- Pre-built Components: No more writing repetitive code for core functionalities like authentication and database access within each microservice.
- Microservices-Friendly Architecture: Maybe the boilerplate supports a microservices approach with pre-configured communication channels and service discovery mechanisms.
- Docker & Kubernetes Integration: Ideally, the boilerplate could provide pre-built Dockerfiles and deployment configurations for Kubernetes, simplifying deployment and freeing you to focus on application logic.


### But Before We Hail the Hero...

Let's be realistic. There are always trade-offs:
- Learning Curve: Any new framework comes with a learning curve, including understanding how to use a boilerplate effectively.
- Customization Concerns: Some boilerplates might limit flexibility, requiring adjustments to fit specific project needs.
- Quality & Maintenance: Ultimately, the effectiveness depends on the quality and ongoing maintenance of the boilerplate itself.


### So, let's Discuss!

I'm curious to hear your thoughts on Java boilerplates, especially with microservices and containerization in mind:
Have you used boilerplates that addressed microservices and deployment complexities?
What features or functionalities would you find most valuable in a boilerplate for streamlining microservices development and deployment?
Are there any drawbacks or limitations you see regarding boilerplates in this context?


### Idea Validation
I'm trying to validate the idea of a Java boilerplate, and I'd really appreciate feedback from you about it.
Try and check it out here: [www.java-boilerplate.com](https://java-boilerplate.com/)

I'm eager to learn from your experiences and explore how Java boilerplates can potentially help us write better, faster, and more scalable microservices applications.

One Byte Explainer: Web Storage
Tags: frontendchallenge, devchallenge, javascript, webdev
Published: 2024-03-28 07:05:09

## Explainer
Web Storage is a browser feature that allows websites to store data locally on a user's device. It provides a way to persistently store data across sessions, enabling applications to cache information, save user preferences, and maintain state. With Web Storage, developers can utilize two types of storage mechanisms: localStorage, which stores data with no expiration date, and sessionStorage, which stores data for the duration of the page session.

## Additional Context
This demo website, [using local storage](itxnargis.github.io/using-local-storage/) is created by me. It demonstrates the implementation of Web Storage in a practical scenario. I built this website to showcase the functionality and benefits of Web Storage firsthand. Feel free to explore and test its features. Whether it's storing user preferences for a customized experience or caching frequently accessed data for faster loading times, Web Storage plays a crucial role in enhancing the performance and usability of web applications.
What is Gen AI?
Tags: genai, osiz
Published: 2024-03-28 06:59:06

Gen AI, short for [Generative Artificial Intelligence Development](https://www.osiztechnologies.com/generative-ai-development-company), is a type of AI that creates new data,  like text, images, music, or even code. It's essentially an AI artist or writer that can produce creative content based on what it's learned. 

Here's a breakdown of how it works:

Learning Patterns: Gen AI is trained on massive amounts of existing data, like books for text generation or paintings for image generation.  By analyzing this data, it learns the patterns and relationships within the content.
Generating New Content: Once trained, Gen AI can use its knowledge to create entirely new pieces of data.  This could be a poem in the style of a famous author, a song with a specific mood, or an image that combines elements from different styles.
Responding to Prompts:  Gen AI can also be interactive. You can provide it with a starting point, like a sentence or a sketch, and it will use that information to create something original that follows your prompt.

Here are some of the key benefits of Gen AI:
Faster Content Creation:  Gen AI can automate tasks like writing reports or designing graphics, saving businesses significant time and resources.
Novel Ideas and Solutions:  By generating new possibilities, Gen AI can help spark innovation and lead to new ideas that humans might not have come up with on their own.
Personalized Experiences:  Gen AI can tailor content to individual preferences, creating a more engaging user experience.

However, it's important to remember that Gen AI is still under development. The generated content may not always be perfect, and it's crucial to ensure the AI is trained on high-quality data to avoid biases or errors in the outputs.

Unraveling the Mysteries of JavaScript, Tackling Tough Logic
Published: 2024-03-28 06:42:52

**Introduction:**
JavaScript, with its flexibility and power, often presents developers with challenges that test their problem-solving skills to the limit. In this post, we'll dive deep into some of the toughest logic problems in JavaScript and unravel the solutions step by step. From tricky algorithms to mind-bending puzzles, get ready to sharpen your JavaScript skills and conquer the toughest of challenges.

**Problem:** Palindrome Check
One classic problem that can stump even seasoned developers is checking whether a given string is a palindrome or not. A palindrome is a word, phrase, number, or other sequences of characters that reads the same forward and backward. For example, "radar" and "madam" are palindromes.

**Approach:**
To solve this problem, we'll compare characters from the beginning and end of the string, moving towards the middle. If all characters match, the string is a palindrome.

function isPalindrome(str) {
    // Remove non-alphanumeric characters and convert to lowercase
    str = str.replace(/[^A-Za-z0-9]/g, '').toLowerCase();
    
    // Compare characters from start and end
    for (let i = 0; i < Math.floor(str.length / 2); i++) {
        if (str[i] !== str[str.length - 1 - i]) {
            return false;
        }
    }
    return true;
}

// Test cases
console.log(isPalindrome("radar"));  // Output: true
console.log(isPalindrome("hello"));  // Output: false
console.log(isPalindrome("A man, a plan, a canal, Panama"));  // Output: true

**Explanation:**

1. We first remove non-alphanumeric characters from the input 
 string using a regular expression and convert the string to 
 lowercase to handle case-insensitive comparisons.
2. Then, we use a for loop to iterate through the characters of 
 the string from the beginning towards the middle.
3. Inside the loop, we compare each character with its 
 corresponding character from the end of the string. If any pair 
 of characters doesn't match, we return false, indicating that 
 the string is not a palindrome.
4. the loop completes without finding any mismatches, we return 
  true, indicating that the string is indeed a palindrome.

**Conclusion:**
By understanding and mastering these tough logic problems in JavaScript, you'll not only enhance your problem-solving skills but also gain a deeper insight into the intricacies of the language. Keep exploring, keep learning, and keep pushing the boundaries of what you can achieve with JavaScript. Happy coding!
Learning new language in context with chatGPT

Published: 2024-03-28 06:37:38

I used to love learning new words from flashcards. But later I started wanting a more richful type of learning. For example reading texts which use the words I'm learning. So called, learning in context.

But how to get a text with particular words You want to learn? Here's where chatGPT comes into play. My workstation looks like this:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/tnz92cfpznwbx2um3rl5.png)

1. I ask chatGPT to generate me a text;
2. While reading it, I'm translating the words which I don't know and adding them to the list;
3. After finishing the text, I generate a new text asking chatGPT to include the words from the list.

A sample command to chatGPT might be:
_Give me text (of ~300 words) of another topic of level B2 with the commonly used words in German and with the following words (they can be in different forms and in different order): ..._

In such way I can learn words (of various forms) in the context.
