## Weekly Challenge 273

Each week Mohammad S. Anwar sends out [The Weekly Challenge](https://theweeklychallenge.org/), a chance for all of us to come up with solutions to two weekly tasks. My solutions are written in Python first, and then converted to Perl. It's a great way for us all to practice some coding.

[Challenge](https://theweeklychallenge.org/blog/perl-weekly-challenge-273/), [My solutions](https://github.com/manwar/perlweeklychallenge-club/tree/master/challenge-273/sgreen)

## Task 1: Percentage of Character

### Task

You are given a string, `$str` and a character `$char`.

Write a script to return the percentage, nearest whole, of given character in the given string.

### My solution

Let's talk about 'nearest integer', and rounding. When you go to supermarket and something costs 45¢, you generally will be charged 50¢ if paying with cash and your currency doesn't have a 5¢ coin. This is called [cash rounding](https://en.wikipedia.org/wiki/Cash_rounding), and probably what you were taught at school.

Python uses [bankers rounding](https://rounding.to/understanding-the-bankers-rounding/), where numbers are rounded to the nearest even. Therefore both 35¢ and 45¢ would be rounded to 40¢, while the sum remains the same (80¢).

This task is ambiguous as it does not mention which method to use when the percentage is a half figure. I've used the cash rounding method, as the sixth example supports this.

For this task, I take the number of characters that occur in the length of the string divided by the length of the string multiplied by 100 + 0.5 (for the rounding).

```python
def char_percentage(s: str, char: str) -> int:
    return floor(s.count(char) / len(s) * 100 + 0.5)
```

The Perl solution is a bit more involved, as I don't believe there is a way to count the number of characters in a string. For this solution, I loop through each character and increase the `occurrences` value if is `char`.

```perl
my $occurrences = 0;
for my $pos ( 0 .. length($str) - 1 ) {
    if ( substr( $str, $pos, 1 ) eq $char ) {
        $occurrences++;
    }
}

say int( $occurrences / length($str) * 100 + 0.5 );
```

### Examples

```bash
$ ./ch-1.py perl e
25

$ ./ch-1.py java a
50

$ ./ch-1.py python m
0

$ ./ch-1.py ada a
67

$ ./ch-1.py ballerina l
22

$ ./ch-1.py analitik k
13
```

## Task 2: B After A

### Task

You are given a string, `$str`.

Write a script to return `true` if there is at least one `b`, and no `a` appears after the first `b`.

### My solution

There are two likely ways to perform this task. One would be to take the position of last `a` (or -1 if there is no `a`) and check this is less than the position of the first `b`.

The second option is to use regular expressions. This is the approach that I took. The regexp I used is `^[^b]*b[^a]*$`. This matches zero or characters other than `b`, a `b` and then makes sure there are no `a`s after that.

### Examples

```bash
$ ./ch-2.py aabb
True

$ ./ch-2.py abab
False

$ ./ch-2.py aaa
False

$ ./ch-2.py bbb
True
```
SteamVR Overlay with Unity: Introduction
Tags: unity3d, steamvr, openvr, vr
Published: 2024-06-16 10:31:29

This tutorial will guide you through creating a SteamVR overlay application in Unity using the [OpenVR API](https://github.com/ValveSoftware/openvr). Overlay applications are suitable for various utilities since they can be launched simultaneously with VR games.

## Sample Application

We will create a simple watch overlay application. The watch is hidden by default, and a controller button will display it for a few seconds. (Click to play GIF animation)

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/290yo7e0jvnyqlfjow46.gif)

We will also create a dashboard to switch which hand to display the watch.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ea6nrhzjriksm21g78qs.gif)

## Prerequisites
Everything in this tutorial is confirmed to work in the following environment.

- [SteamVR](https://store.steampowered.com/app/250820/SteamVR/) beta 2.5.2
- [Unity](https://unity.com/) 2022.3.21
- [SteamVR Unity Plugin](https://assetstore.unity.com/packages/tools/integration/steamvr-plugin-32647) v2.8.0 (OpenVR v2.0.10 included)

Type conversions (Also known as Type Casting) in Python
Tags: devchallenge, cschallenge, computerscience, beginners
Published: 2024-06-16 10:21:10

When we convert the value of one datatype into another datatype then it is known as type conversion. There are two types of type conversions:
1.	Implicit Type Conversion
2.	Explicit Type Conversion

## Implicit Type Conversion
In this type conversion python automatically converts a value of one datatype into another datatype. It will convert datatype having lower preference to the datatype having higher preference.

### Code Example:


![Type Conversion](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/9ih4rrviwiy2m7r99vn8.png)

Output:


![Type Conversion Output](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/hgt99waxe9tdqs7wwzcr.png)

Since float has higher preference so the output will also be in float. This is very useful because we will not loose our data.
But there are some values of one datatypes which can be converted another implicitly. That’s why we have explicit type conversions.

## Converting integer to string

### Code 


![Converting INT TO STR](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ggnbbzzqnnqgz9mwc0e5.png)

Output


![INT TO STR Output](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/tn5lmet5lwizzcdhvdlk.png)

## Explicit Type Conversion
In explicit type conversion, the user has to mention explicitly to which value of one datatype he/she wants to convert to another datatype. This can be done by using predefined functions like int(), str(), float().

### Code 


![Explicit Type Conversion](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/s03nzezw4ax7gcn7d5yi.png)

Output


![Explicit Type Conversion Output](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/lbmpqq2unh0914i8f3dl.png)

I hope you were able to understand type conversions in python. Do comment below in case of any doubts.
Rejected, Not Deflected: My Journey After Out in Tech
Tags: webdev, technology, lgbtq, mentorship
Published: 2024-06-16 10:07:57

Landing a mentor can be a game-changer in the tech industry. As an aspiring LGBTQ+ developer, I was particularly drawn to Out in Tech’s mentorship program. Not only does it champion inclusivity, but the project-based approach with a dedicated mentor seemed like the perfect fit for my learning style. Unfortunately, my application wasn’t selected this time around.

While rejection can be discouraging, it hasn’t deterred me. Out in Tech’s mission of fostering a supportive environment for LGBTQ+ professionals resonates deeply with me. I understand that competition for spots must be fierce, and I was eager to learn more. I sent a follow-up email to the program manager inquiring about successful applicant profiles and future program cycles, but haven’t received a response — a small hurdle in the grand scheme of things.

Instead of dwelling on the “no,” I’ve focused on the “how.” My hunger for knowledge hasn’t diminished. I’ve actively sought other avenues for growth. Participating in fellowships like DataTalksClub and 100 Devs, alongside earning a micro-credential from Queensborough’s Software Engineering Bootcamp, has kept my momentum going.

The tech industry demands not just technical prowess but also resilience. While a mentor would have been fantastic, this setback has ignited a fire within me. It’s a reminder that the path to success rarely follows a straight line. My journey may have taken a detour, but the destination remains the same — to become a skilled and impactful developer within an inclusive tech space.

This experience has underscored a valuable lesson: sometimes, the best opportunities arise from unexpected rejections. My dedication to learning hasn’t wavered, and I’m one step closer to achieving my goals. For other aspiring LGBTQ+ developers out there, remember: your grit and determination are just as valuable as your technical skills. Keep pushing forward, and success will follow.
@Autowired magic in SpringBoot
Tags: webdev, programming, springboot
Published: 2024-06-16 10:01:26

**Disclosure:** I'm quite an experienced developer (currently go/python/bit of rust, scala/c# in the past), but a newbie when it comes to Spring Boot. 

Recently, I've had to use it in one of my projects and somewhere in the code, I've come across this interesting annotation:
`@Autowired`

When I've read about it, I couldn't believe my eyes:

> In Spring Boot, the @Autowired annotation is used for automatic dependency injection. 
This means that Spring will automatically resolve and inject any beans that your object depends on.

I'm familiar with Dependency Injection, but I've never thought that anyone could use, or even propose to use, such an approach. 

It's pure magic. I strongly believe that DI should be explicit, and the developer should be aware of what dependencies are injected into his/her class.

Here is, in my opinion, a much better approach to the problem:
https://github.com/google/wire

Wire is a compile-time dependency injection tool. Dependencies are defined in a separate file, and the developer is always aware of what is injected into his/her class. 

I'm curious about your opinion on this topic. Do you think that @Autowired is a good approach to DI? Or maybe you prefer a more explicit approach like Wire? Or maybe you have your own way of doing DI? I'm looking forward to your answers.

Polling in Vue.js
Tags: javascript, webdev, tutorial, vue
Published: 2024-06-16 09:35:59

Designing a composable in Vue.js to continuously poll data after the "x" interval.

### What is Polling?

It is defined as the process when a client requests a particular piece of data at regular intervals (maybe every x seconds) and the server reverts with a usual response with the required data.

[read more](https://www.geeksforgeeks.org/polling-and-streaming-concept-scenarios/)


### Composable

Let's write a composable `usePolling` inside `src/composables/usePolling.ts`

```js
import { ref, onMounted, onUnmounted } from "vue";

const usePolling = (method, timeInterval = 10000) => {
  const interval = ref(null);
  const callMethod = ref(method);
  const isPolling = ref(false);

  const clear = () => {
    clearInterval(interval.value);
    interval.value = null;
    isPolling.value = false;
  };

  const fetchData = (poll = true) => {
    callMethod.value();
    if (poll) {
      // start interval
      interval.value = setInterval(() => {
        callMethod.value();
      }, timeInterval);
    } else {
      clear();
    }
  };

  const start = () => {
    // clear any existing polling calls
    clear();
    // set polling flag to true
    isPolling.value = true;
    // fetch data
    fetchData();
  };

  onMounted(() => isPolling.value && fetchData());

  onUnmounted(clear);

  return {
    start,
    clear,
  };
};

export default usePolling;

```

### Component:

Now, let's use this composable inside any component.

```js
<script setup>
import { onMounted } from "vue";
import usePolling from "../composables/usePolling";

const apiCall = async () => {
  console.log("api call");
  // const response = await fetch("https://jsonplaceholder.typicode.com/todos/1");
  // const data = await response.json();
  // console.log(data);
};

const { start, clear } = usePolling(apiCall, 1000);

onMounted(start);
</script>

<template>
  <h1>Hello world!</h1>
</template>
```
