Willy Wonka contract effect using CSS?
Tags: css, javascript, webdev
Published: 2024-01-12 03:18:39

I want a long paragraph of text to progressively reduce its font size, like the contract in Willy Wonka (see below). 

Criteria could be character count or line count. I think either would work fine. 

Is there a CSS solution? First thought was `line-clamp` or something like that. 

Thought I'd try my luck here in hopes some adventurous souls were up.

Returning to fullstack development
Tags: beginners, tutorial
Published: 2024-01-12 03:07:36

Hi! This is my first post. I actually found this community after a quick search on Google. My point is that I was a full-stack developer many years ago, maybe 10. My career led me to PLC programming, and I left almost all of the web design, PHP, ASP, MySQL, JavaScript, and other common resources used in those days. Now, I have a good level of proficiency in Python, but I want to revisit all this knowledge to create web apps, a website, and develop useful tools to integrate with my current career in automation. However, I feel lost in this matter, and my question is: Where can I start to get updated on front-end and back-end environments again?.
I just failed my coding test...heres the passing solution
Tags: programming, python, leetcode, career
Published: 2024-01-12 03:04:28

So I just failed my coding test due to running out of time. It was one of those codility tests only 70 minutes and 3 different problems, I passed on the first 2 questions however I ran out of time with the 3rd problem.


Here is the question that gave me issues


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/mpa4eui1c962z72uzn2k.png)


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/d8v10ykho1aq10f3r0w5.png)


initially I assumed we would need to use the sliding window technique to get the contiguous 'x' and measure from there and I hacked at that solution for about 20 minutes but in the final 5 minutes out of pure desperation and need i came up with another solution that i did not get to fully flesh out in the official test. 


The idea of the solution is in 3 simple broken up steps,

1. separate the contiguous x
2. sort by length
3. decrement from your budget


this solution is magnitudes simpler to comprehend and a LOT easier to read. I may not have gotten the ability to benefit from coming up with this solution but hopefully someone reading this in the future will.


here it is in python

```python
def solution(S, B):
    # Implement your solution here
    count = 0

    #sliding window technique needed
    arr = []
    temparr = []
    for index in S:
        if index == "x":
            temparr.append(index)
        else:
            arr.append(len(temparr))
            temparr = []
    arr = sorted(arr)
    index = len(arr)-1
    while B > 0 or index == 0:
      if B >= arr[index]+1:
        B -= arr[index]+1
        count += arr[index]
      index -= 1
    return count
```
Leetcode Challenge - Two Sum (#1) | Hashmap & hasOwnProperty method
Published: 2024-01-12 02:46:32

Diving into the LeetCode world has been a wild ride for me! I tried everything that I could, but I always got stuck at some test.

Although I learned an important thing: we need to keep studying, no matter when. Sometimes we get tired of the job, of studying, and everything, but it's important to keep up the study and exercise your brain somehow.

During my first try, I tried using everything I knew, but I didn't pass all the tests. I always messed up at some point.

Studying the possible solutions, I came across with "**Hashmap**" and when I tried to apply it through ChatGPT, he gave me the answer. I didn't mean it.

Well, I felt like a failure when I came across the solution, but at least I wanted to really understand what's going on, and I'll tell everything that I learned in this LeetCode problem.

---

**Two important lessons:**
_1. Understanding Hash maps and their application in JavaScript._

Hash map basically it will always follow the pattern of key-value. In JavaScript, hash maps are represented as objects, offering a quick and efficient way to organize and access data. Think of them as labeled boxes where each item (data) has a unique key. Retrieving, adding, and managing data becomes faster and more organized, making hash maps a powerful tool for various programming tasks.

For example:
```js
// Creating a simple hash map in JavaScript
let userPreferences = {
  'theme': 'dark',
  'language': 'javascript',
  'fontSize': 'medium'
};

// Accessing data using keys
console.log(userPreferences['theme']);  // Output: dark

// Adding new data
userPreferences['background'] = 'pattern';

// Hash maps make data retrieval fast and easy
console.log(userPreferences['background']);  // Output: pattern

```

---

_2. Exploring the hasOwnProperty() method in JavaScript._
The hasOwnProperty() method in JavaScript is like a safety check for object properties. It allows you to confirm if an object possesses a specific property before attempting to use it. This helps prevent error and ensures a smoother, more reliable execution of your code by verifying the existence of properties within an object.
For example:

```js
// Creating a nerdy character object
let wizardCharacter = {
  'name': 'Gandalf',
  'powerLevel': 9000,
  'staff': 'The Grey One'
};

// Checking if a magical attribute exists using hasOwnProperty()
console.log(wizardCharacter.hasOwnProperty('name'));  // Output: true
console.log(wizardCharacter.hasOwnProperty('petDragon')); // Output: false

// Safely wielding magical attributes with hasOwnProperty()
if (wizardCharacter.hasOwnProperty('powerLevel')) {
  console.log(`${wizardCharacter['name']}'s power level: ${wizardCharacter['powerLevel']}`);
} else {
  console.log('Power level not found. Did someone steal the spellbook?');
}
```

One Product A Month for #DEVresolutions2024
Tags: devresolutions2024
Published: 2024-01-12 02:25:09

The new year vibe has already settled in and people are getting more drawn into reality. That's when I exactly think this is the best time to make new year resolution. By starting on my own timeline, I know I write this not because of FOMO, but I aim for real progress, instead.

## My 2024 Resolution
I managed to simple and ambitious enough goal in one sentence: 

> **Ship one product per end of month**.


![A shiny ambitious goal? _(source: playground.ai)_](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/lpwsxdfyitpr02nwmuxv.jpeg)
This goal beautifully encompasses all things I aspire to accomplish.
- Open opportunities from various ways
- Focusing on small set of tasks instead of overthinking technical stuff that lead to self-inflicted scope creep (that's my bane, yeah)
- Experience journey beyond coding
- More portfolio is nice bonus as well

## Details, Details, and Details

### Scope
Then, isn't it daunting and overly ambitious? Yes, when we think about "product" as a set of solutions working seamlessly and displayed beautifully. I define output product below to set expectations:
- the product solves one specific real world problem
- the product is deployed on internet
- the product interacts with human users, and optionally with machine users

This might be close to MVP, but not yet. The goal is personal growth, not user feedback or financial. Even in this setup, I will have total freedom to build with Svelte in January and Solid.js in February, and so on. I do not focus on product valuation. However, it is totally possible that output product from this process is further developed as MVP or, with with sufficient resources and time, marketable product.

### How Does This Help DEV Users?
In addition to shipping a prodcut per month, I will also share my journey on DEV about my problem-finding process, my design process, my journey of overcoming obstacles. Hopefully it will help community members.

Wish me luck, and I hope everyone has a blessed and eventful 2024 🎊🎊🍾 🚀
DynamoDB Scan with sort
Published: 2024-01-12 02:16:01

To query and retrieve 100 records from DynamoDB and order them by a sort key column in Node.js, you can use the AWS SDK for JavaScript. Make sure you have the AWS SDK installed and configured. Here's an example code snippet:

```
const AWS = require('aws-sdk');

AWS.config.update({
  region: 'your-dynamodb-region', // Replace with your DynamoDB region
  accessKeyId: 'your-access-key-id', // Replace with your AWS access key ID
  secretAccessKey: 'your-secret-access-key', // Replace with your AWS secret access key
});

const dynamoDB = new AWS.DynamoDB.DocumentClient();
const tableName = 'your-dynamodb-table-name'; // Replace with your DynamoDB table name
const sortKeyColumn = 'your-sort-key-column'; // Replace with your sort key column name

const params = {
  TableName: tableName,
  Limit: 100,
  ScanIndexForward: true, // Set to false for descending order
  KeyConditionExpression: '#sk > :sk', // Replace > with < for descending order
  ExpressionAttributeNames: {
    '#sk': sortKeyColumn,
  },
  ExpressionAttributeValues: {
    ':sk': '0', // Replace with your start key value
  },
};

dynamoDB.query(params, (err, data) => {
  if (err) {
    console.error('Error querying DynamoDB:', err);
  } else {
    console.log('Queried records:', data.Items);
  }
});
