If you’re preparing for a [technical ]interview, it’s important to have a strong understanding of strings in programming. Strings are a common data type that you’ll encounter in many different coding challenges, and mastering them can help you solve problems more efficiently and effectively. In this article, we’ll explore the basics of strings in programming, including what they are, how they work, and some common operations and methods you’ll need to know. By the end of this article, you’ll have a solid foundation for working with strings and be better equipped to ace your next technical interview.

How to solve String-based Coding Problems

A good thing about the string data structure is that if you know the array [data structure](https://cplivly.com/top-50-string-programming-interview-questions-for-beginners-data-structure-and-algorithm/), you can easily solve string-based problems because strings are nothing but a character array.

Q: How do you reverse a string in programming? A: Reversing a string involves flipping the order of its characters. Depending on the programming language, there are multiple ways to reverse a string, such as using a loop or a built-in method like reverse().

Q: What is a substring? A: A substring is a portion of a larger string. It is defined by its starting index and its length, and can be extracted from the original string using a variety of methods.

Q: How do you check if a string contains a certain character or substring? A: To check if a string contains a certain character or substring, you can use methods like indexOf(), contains(), or in the case of regular expressions, match().

Q: How do you convert a string to an integer in programming? A: Converting a string to an integer involves parsing the string and extracting the numerical value. Most programming languages have a built-in method like parseInt() or atoi() to perform this conversion.

Q: What is a regular expression? A: A regular expression is a sequence of characters that defines a search pattern. Regular expressions are often used in string manipulation to search for or replace patterns of characters within a larger string.

Q: How do you remove whitespace from a string in programming? A: Removing whitespace from a string involves trimming the spaces from the beginning and/or end of the string. This can be done using methods like trim(), ltrim(), or rtrim().

Q: How do you compare two strings in programming? A: Comparing two strings involves checking if they are equal or not. In most programming languages, you can compare strings using the “==” operator or a dedicated method, such as equals().

Q: What is the difference between a string and a character? A: A string is a sequence of characters, while a character is a single letter, digit, or symbol. Strings can be composed of one or more characters.
Add simple pagination in Nest.js Mongoose
Tags: javascript, tutorial, node, nest
Published: 2023-04-23 14:48:20

I have been learning to wonderful world of nest.js recently and I want to say it's actually very cool, in fact its fast becoming a favorite of mine to use when building backend.

A thing I struggled with this week was adding pagination into one of my functions that allowed me to switch through my documents. I tried many packages and none of them seemed to do it correct. So I went away and tried to find out the best way to do it and I needed it to be pretty simple. 

Now before I begin I must say this is not a fully fledged Pagination and wont give you all the functions you would want in most cases. But what this will do is give a simple way to move between stacks of data and have a page count.

So we are using MongoDB and Nest.js and I am assuming you have this set up and you are ready to go.

So we have a entity set up and we have out Controllers and Services all sorted. So lets start with the controller.

```javascript
    @Get('get')
    async getdata(@Query() {limit, skip}) {
        return this.testService.getTests(
            skip,
            limit)
    }
```

What we have above is a simple controller function that gives us a end point of '/get' and the returns the service passing in two params that are Skip and Limit. The skip and limit params are carried through the URL and the @Query picks those up.

```
/get?skip=8&limit=8
```

So lets head over to the service so we can see what we are doing here

```javascript
async getTests(
      skip = 0,
      limit = 8,
      ) {
      const count = await this.testModel.countDocuments({}).exec();
      const page_total = Math.floor((count - 1)/ limit) + 1;
      const data =  await this.testModel.find().limit(limit).skip(skip).exec();
      return {
        data: data,
        page_total: page_total,
        status: 200,
      }
  }
```
Ok what we have here is the service taking the skip and limit and adding default values to them. 

With the below line we count the documents and do some math to determine what the page count is. 

```javascript
const count = await this.testModel.countDocuments({}).exec();
      const page_total = Math.floor((count - 1)/ limit) + 1;
```

Then we grab the data from the Mongo Database and pass our skip and limit to the find(). After all that we simple return our page totals and data.

Its a really simple way to have pagination and allows us to move through data.

Thanks for reading and have a fine Sunday!
Nuxt.js vs Next.js
Published: 2023-04-23 14:18:55

As I was updating my old #vuejs 2 online portfolio, I had the opportunity to test both #nextjs and #nuxtjs. While both frameworks have their own strengths and weaknesses, I found that Nuxt.js excels in terms of features and functionality.

One of the areas where Nuxt.js shines is its ease of installation. When starting a new project with Nuxt.js, you can choose to install additional dependencies like #bootstrap and #typescript, and configure linting and testing options. In contrast, Next.js requires you to set up these features yourself, which can be more time-consuming.

Nuxt.js also has a superior content fetching system, thanks to its $content syntax. With this syntax, you can easily fetch and sort content, as well as access next/previous elements. This makes content management more integrated with the #framework, unlike Next.js where you need to implement your own system.

In terms of page display, both frameworks have similar routing systems. However, Nuxt.js includes a #tailwindcss tester that displays the styles activated by the page config. This feature eliminates the need to mentally combine the documentation and config file, making it easier to develop and maintain your code. Additionally, Nuxt.js has a system that allows you to edit text and preview it in the browser directly, making it easier to create and update pages and blog articles.

Lastly, I want to highlight image handling. In my experience, Nuxt.js's nuxt-img is superior to Next.js's next/image. With next/image, it automatically wraps the img in a div and adds some CSS, which can sometimes cause unexpected behavior. Adding a width attribute can also break the image scaling. Nuxt-img, on the other hand, offers a simpler and more flexible way to handle images.

Overall, both Next.js and Nuxt.js have their own unique strengths and weaknesses, but I found Nuxt.js to be the more comprehensive and user-friendly option.

Completing Forrest Brazeal's Resume Challenge - Part 2
Published: 2023-04-23 14:04:58

Now that the website is up and running via Cloudfront, it's time to look at some loose ends and start on the Web API portion.

## More Terraform for Namecheap.com

One of the things that bugged me was that I set up the subdomain `resume.jimbledsoe.me` on both the AWS and Namecheap side by hand. I found out after-the-fact that Namecheap had a Terraform provider.

I dug into it a little bit further and found out that they have requirements to get an API key that I probably won't meet. One requirement is to have 50 domains with them - I don't have that. Another is to spend $50/yr with them or have a $50 balance in your account, and I don't have that, either.

So it looks like automating the subdomain configuration will remain as a hand-made step. I will likely change the subdomain later to `aws.jimbledsoe.me` to be more flexible for future projects and also make it more logical once I start registering subdomains for other cloud providers. But I will not worry over this just yet.

## Configuring a Simple Web API with Serverless Application Model (SAM)

I decided to work from the bottom-up on the visitor counter and Web API so there is less rework. I will deploy just a sample SAM application from the AWS catalog as-is, and then keep expanding on it, since there are five or six issues related to building it up.

The order I will likely be working on the Web API are as follows:

1. Implement Lambda as a SAM CloudFormation
1. Store Visitor Counter in DynamoDB
1. Visitor Counter should implement Lambda API to interact with DynamoDB
1. Include unit tests for Python Lambda
1. CI/CD for Lambda Web API
1. Resume page includes a visitor counter

I may move the unit tests up the priority stack, but until I actually get the Lambda doing something significant, there' not much to test. I will just be hard coding the API to return 1 as the count until it gets to the DynamoDB parts.

The CI/CD I may move up earlier, too. The only reason I have it so low on the list is because it needs to deploy only if all the unit/integration tests pass. There's plenty of chicken-and-egg to it at this point.

I have broken down the issues as they are now, just to line up with the numbered requirements (1-14) posted in the challenge. I probably would have broken them down a little differently if I was building this up myself. But that's also part of the fun of this - flex to what you are given for requirements and built it up from tiny pieces one-by-one.

## Conclusion

The SAM implementation was easy since I am only publishing a hello-world template as of now. There was a template for a DynamoDB backed API as a template, but they did not have a Python version, so it ended up just being a `hello world` Lambda. Adding DynamoDB should be easy.

The IAM permissions were much easier for this, too, since the SAM documentation said just add these six-or-so policies, which were ones like `AWSLambda_FullAccess` and other "full-access" policies. I may end up reworking the IAM later based on "full-access" for the resources Terraform is working with.
hooks for handling fetch data and use react query
Tags: react
Published: 2023-04-23 13:54:32

In this example, we've imported the useFetchData hook and called it with the API endpoint URL. The useFetchData hook returns the same object that the useQuery hook returns, so we can use the same conditional rendering logic to handle loading and error states.

Using custom hooks like this can make your code more modular and reusable, and it can also make it easier to switch between different data fetching libraries (such as switching from React Query to another library) in the future if necessary.

```
import { useQuery } from 'react-query';

function useFetchData(url) {
  return useQuery(['data', url], async () => {
    const response = await fetch(url);
    const data = await response.json();
    return data;
  });
}

export default useFetchData;
```

```
import React from 'react';
import { View, Text } from 'react-native';
import useFetchData from './useFetchData';

function MyComponent() {
  const { isLoading, isError, data, error } = useFetchData('https://api.example.com/data');

  if (isLoading) {
    return <Text>Loading...</Text>;
  }

  if (isError) {
    return <Text>Error: {error.message}</Text>;
  }

  return (
    <View>
      {data.map(item => (
        <Text key={item.id}>{item.name}</Text>
      ))}
    </View>
  );
}

```
30 days of Rust - Motivation
Tags: rust, python, learning, community
Published: 2023-04-23 12:54:38

## Get inspired
When was the last time you read a book or listened to a podcast and felt inspired? 

Now I know that as programmers we encounter tasks on a daily basis with often *interesting* or *unique-ish* challenges. And solving them can lead us to feel anything from pride to frustration or boredom. 

These feelings may move you to take action (taking a nap when you're bored, for example). But the effect inspiration can have on you is of a different order of magnitude. Inspiration causes your mind to race with ideas and possibilities; it makes you want to stop what you're doing and reassess your priorities; it can drastically alter the course you are on in life.

What do my unoriginal musings about inspiration have to do with learning Rust? Returning to the opening line of this article, my answer would be: *this week*. Having attended my first PyCon conference in Berlin, I found myself in talks that left me energised and impassioned: new age DataFrames with Polars, ML components in databases, and wearables with embedded LLMs.

## Rusty Python: genuine synergy or just hype?
A fascinating fact about the conference was the number of Rust-focused talks. From language comparison, to optimised DataFrame APIs, Rust seemed to be at the centre of attention at Germany's largest *Python* conference. As an professional Python developer, I began to think about how Rust could help me grow. And with some of the biggest libraries (e.g. Pydantic) and frameworks (e.g. pandas) being rewritten or reimplemented in Rust, I began to see a future Python ecosystem built on top of Rust.

Python's package ecosystem is rich, and as a language loved by the scientific community, there are dozens if not hundreds of projects which could benefit from compute- and memory-optimised implementations in Rust. Rust is obviously not the only language that can make such optimisations, but it seems to be the tool of choice for smart developers who are doing those rewrites. I'd love to comment on why programmers are opting for Rust, but as I know nothing about Rust (:D) I'll come back to that question after 30 days.

Ultimately PyCon gave me some inspiring rusty thoughts: doing a library rewrite of my own (especially for horrible Java ports); learning new kinds of computer science abstractions; and generally becoming a more valuable developer.

## What's next?
Over the next thirty days I will be documenting my journey of learning Rust through open-source content. Hopefully, I'll be just as inspired at the end of my journey as I am now - but no promises there!
Hugo- The Best Static Site Generator
Tags: hugo, webdev, html, css
Published: 2023-04-21 19:16:56

The process of creating a website from scratch can be an exhausting process and requires tonnes of knowledge about web development, especially HTML, CSS and JavaScript. Often, the time taken to develop a website may not be worthwhile. One of the most prominent solutions to this problem right now is Hugo- a very fast, flexible and free open source framework for building static websites.

**What are Static Sites?**

A static site is a website that consists of web pages with fixed content that is pre-written and does not change dynamically. This means that the content of the website is created and stored in HTML, CSS, and JavaScript files that are uploaded to a web server and served to users when they visit the site.

Hence, static websites do not require knowledge of database management and are comparatively easier to develop as compared to dynamic sites. Static sites are mostly used for webpages with low content and less frequent updates. This makes such type of sites the most used for personal blogs, online portfolios, etc.

**Why Hugo?**

1.  Speed

Hugo is one of the fastest static site generators available. It has a lightning-fast build process that can generate a site in just a few seconds. This is especially useful when you need to update your site frequently, and you don't want to spend a lot of time waiting for the build process to finish.

2. Easy to Use

Hugo is designed to be simple to use. You don't need to have any programming knowledge to get started with Hugo. The tool provides a simple command-line interface that allows you to create and manage your website easily.

3. Security

Static sites are known for their security benefits, and Hugo is no exception. Since Hugo generates static HTML files, there are no databases or server-side scripts that can be exploited by hackers. This makes your website more secure and less vulnerable to attacks.

4. Flexibility

Hugo is a highly customizable tool that allows you to create the website you want. You can choose from a wide range of templates and themes that suit your website's needs. Additionally, you can use custom CSS and JavaScript to further customize your site.

5. Large Community

Hugo has a large and active community that provides support and resources to users. There are many online forums, documentation, and tutorials available to help you get started with Hugo.

6. Customization

Hugo offers a vast number of community themes which make building a site even easier, and give websites an amazing look.

**Conclusion**

Hugo is a powerful tool that offers many benefits to website owners and developers. It is fast, easy to use, secure, flexible, and has a large community. With Hugo, you can create a professional-looking website in no time. Whether you're building a personal blog or a business website, Hugo is definitely worth considering as your static site generator of choice.
