Tags: webdev, programming, chatgpt, ai
Published: 2023-02-15 15:25:25

As a software developer, you are constantly looking for ways to write code more efficiently and effectively. That's where ChatGPT comes in. ChatGPT is an AI-powered language model that has the ability to generate code, answer coding questions, suggest optimizations, and automate testing. In this article, we'll explore the top 5 ways to use ChatGPT to help you write code as a software developer.

Generate Code Snippets

One of the most powerful capabilities of ChatGPT is its ability to generate code snippets based on natural language descriptions. This can be incredibly useful when you need to quickly implement a piece of functionality or automate a repetitive coding task. For example, if you need to write a function that calculates the sum of two numbers, you could simply describe the function in natural language ("a function that takes two numbers as input and returns their sum") and let ChatGPT generate the code for you.

Answer Coding Questions

Another useful way to use ChatGPT is to ask it coding questions and get immediate answers. ChatGPT has been trained on a vast corpus of technical documentation and code snippets, so it can provide guidance on programming best practices, help debug code, and suggest solutions to common coding problems. For example, if you're unsure about the syntax for a particular programming language or library, you could ask ChatGPT for guidance and get a quick and accurate response.

Optimize Code Quality

ChatGPT can also be used to suggest optimizations and improvements to existing code. By analyzing your code and identifying areas where performance can be improved or where best practices are not being followed, ChatGPT can help you write better code in less time. For example, ChatGPT can suggest more efficient algorithms for complex computations, or recommend alternative data structures for storing and manipulating data.

Automate Testing:

Testing is an essential part of software development, but it can be time-consuming and tedious. ChatGPT can help automate testing by generating test cases and analyzing code coverage. This can help you identify bugs and performance issues before they become a problem, and can also save you time and effort in the testing phase of development. For example, ChatGPT can generate test cases for edge cases or specific input scenarios, which can be difficult to come up with manually.

In conclusion, ChatGPT is a powerful tool that can help software developers write better code in less time. By using ChatGPT to generate code snippets, answer coding questions, optimize code quality, automate testing, and collaborate with peers, you can improve your coding workflow and accelerate your development cycle. While there are limitations and challenges to using ChatGPT for coding, such as its reliance on training data and potential biases, with proper usage and integration, ChatGPT can be a valuable asset to any software development team.

This will remove all stopped containers
React vs svelte vs angular vs vanilla js vs vue
Published: 2023-02-15 20:32:50

React, Svelte, Vue, VanillaJS, and Angular are all popular front-end JavaScript frameworks and libraries used for building dynamic and interactive web applications. Here's a brief overview of each one with a 'hello world' example:

React: Developed by Facebook, React is a widely adopted JavaScript library for building user interfaces. It's a component-based library that allows you to easily manage and update the state of your UI, making it a popular choice for large-scale, complex applications.

```
import React from 'react';

function App() {
  return (
    <div>
      <h1>Hello World!</h1>
    </div>
  );
}

export default App;
```

Svelte: Svelte is a new and emerging framework that is gaining popularity in the JavaScript community. It is a compiler-based framework that compiles the code at build time, which allows for smaller bundle sizes and faster performance. Svelte is also known for its simplicity, ease of use, and the ability to write less code to achieve the same functionality compared to other frameworks.
```<script>
  let name = 'World';
</script>

<h1>Hello {name}!</h1>
```

Vue: Vue is a progressive JavaScript framework that is designed to be easy to use and flexible. It's known for its ease of integration with existing projects and the ability to scale up or down depending on the size of the project. Vue also provides a wide range of features out-of-the-box, including a state management system and component-based architecture.

```
<template>
  <div>
    <h1>Hello {{ name }}!</h1>
  </div>
</template>

<script>
export default {
  name: 'App',
  data() {
    return {
      name: 'World'
    }
  }
}
</script>
```

VanillaJS: VanillaJS, also known as plain JavaScript, is the native JavaScript language without the use of any libraries or frameworks. While it requires more coding than the other frameworks, VanillaJS is a great option for small projects, and it can also be used alongside other frameworks.

```
<!DOCTYPE html>
<html>
  <head>
    <title>Hello World</title>
  </head>
  <body>
    <h1 id="myHeading">Hello World!</h1>
    <script>
      document.getElementById('myHeading').textContent = 'Hello World!';
    </script>
  </body>
</html>
```

Angular: Developed by Google, Angular is a comprehensive framework that provides a full set of features for building complex web applications. It's known for its strong opinionated structure, dependency injection system, and advanced features like two-way data binding and powerful directives.

```javascript
import { Component } from '@angular/core';
@Component({
  selector: 'app-root',
  template: '<h1>Hello {{ name }}!</h1>',
})
export class AppComponent {
  name = 'World';
}
```

In conclusion, the choice between these frameworks ultimately depends on the project's specific requirements, developer preferences, and the team's expertise. All these frameworks have their strengths and weaknesses, and it's essential to consider them while choosing a framework for a particular project.

## traceroute ##

traceroute is a tool to trace the path of an IP packet as it traverses routers, and it is a great utility for checking the route from a source to a destination. The traceroute command is one of the simplest yet most effective ways to troubleshoot network problems.

NOTE: 
- Different platforms offer traceroute as a tool, such as TRACERT on Windows or TRACEROUTE on Linux and Mac.
- Installation steps on both platforms are pretty simple, since we will be talking about Linux (Ubuntu). Below are the steps to get this utility installed.
- If you are on RHEL family, you can get this installed by `yum`.

```
$ apt-get update -y 
$ apt get install traceroute -y
```

Here are some examples of how to use the traceroute command in Linux:

To perform a traceroute to a host:
```
$ traceroute google.com
```

To perform a traceroute to a host with the IP address:
```
$ traceroute 142.250.77.78
```

To perform a traceroute with a maximum of 10 hops:
```
$ traceroute -m 10 google.com
```

To perform a traceroute with a maximum wait time of 2 seconds per hop:
```
$ traceroute -w 2 google.com
```

To perform a traceroute with only one packet sent per hop:
```
$ traceroute -q 1 google.com
```

Feel free to check its capabilities via `man traceroute`

What is your opinion about this topic?
What I will share is specifically from my point of view.

For years I have lived a solitary life, few people around me, but it doesn't really affect me and it doesn't bother me, but is it correct in the world of programming?
In my current job we are few programmers and we have little interaction and it's good because everyone works on their own and then we compare our work or share doubts, but I firmly believe that by sharing with more people your knowledge increases.

Being alone in the programming world or surrounding yourself with other programmers?

How to use v-model in render function vue 3 composition API?
Published: 2023-02-16 18:52:30

**Introduction:**
This article focus on v-model in render function with two kinds of components, custom components and pre-built components. From the official document on VueJs, v-model directive is expanded to modelValue and onUpdate:modelValue props during template compilation—we will have to provide these props ourselves:

`export default {
  props: ['modelValue'],
  emits: ['update:modelValue'],
  render() {
    return h(SomeComponent, {
      modelValue: this.modelValue,
      'onUpdate:modelValue': (value) => this.$emit('update:modelValue', value)
    })
  }
}
`
Soon, you will be confused about where to use the emits and props. In most cases, emits and props are defined in child components and render functions are used in parent components.
Render function applications in custom components:
Let’s define the child component first.
Child Component
`<template>
<div>
  <ul>
    <li v-for="(tag) in props.title" :key="tag">
      {{ tag }}
    </li>
  </ul>
</div> 
</template>
<script lang="ts" setup>
const props = defineProps({
    title: String
})
</script>`
We need a props from parent components to pass data to child components. So, title is the props in the child component. The we need to pass data to title in render function from parent component.
`<script lang="ts" setup>
render(){
	return h(
		 Childcustomcom,
	{
		‘title’:[‘hello’,’this’,’is’,’array’],
	}
)
}

<script lang="ts">
import Childcustomcom  from './childcustomcom.vue'

export default{
  name: 'customcom',
  components: {
    Childcustomcom
  }
}
</script>`

Now we are done with props. Then we need to pass data from the child component to parent component. We need an emits. 
child Component
`<template>
<div>
<input v-model="newTag" type="text" @keydown.enter= "handleinput()" />
  <ul>
    <li v-for="(tag) in props.title" :key="tag">
      {{ tag }}
    </li>
  </ul>
</div> 
</template>
<script lang="ts" setup>
const props = defineProps({
    title: String
})
const newTag = ref('')
const emit = defineEmits(['addTag'])
function handleinput(){
	emit(‘addTag, newTag.value)
}

</script>`
In side render function we need v-on to trigger the event. V-on in render function is on the capitalized 
`render(){
	return h(
		 Childcustomcom,
	{
		‘title’:[‘hello’,’this’,’is’,’array’],
		‘onAddTag’ : (value) ={
			console.log(value)
					},
	},
)
}`
Render function applications in pre-built components:
We use the example from the Naive UI components. https://www.naiveui.com/en-US/os-theme/components/dynamic-input
Ninput has dynamic props including v-model value (Value in controlled mode)
but we cannot the value props directly, it will cause error.
Inside render function:

`render(){
        return h(
        NInput,
        {   
            'default-value': customvalue,
            'on-change': (v:string)=>{
                customvalue=v
            },
            type:"text", 
        })}
    },

const customvalue = ref(‘’)

`Here we need on-change call back function to update the value from input to customvalue, the default-value props to give the initial value to ninput.
Knowing what content to create
Published: 2023-02-16 19:09:04

Knowing what to write, what do I mean? I'll tell you, for most people they have a confliction on what kind of content they want to put out, it's easy to get fixated on that and loose sight on the most important thing Which is providing value, people are looking for help and they are looking for it everywhere especially on the internet. During the pandemic alot of people where consuming content like wild fire and one thing I found quite interesting is the amount of "how-to's" content that were being sold.
I saw a scenario where a working class couple that never used to be at home pre- pandemic invested in purchasing a how to stop shouting tutorial, apparently they couldn't cope with all the chaos that came with having so many kids at home at the same time. My point is people will consume any content they find helpful at the time.
So Incase you thought you needed permission to start, here it is, you need to start today, nobody has ever been great at anything on their first day but a ton of people achieved greatness by putting in the work.
Start today, start now and be great
Semiology in Ruby (What are Ruby Symbols) ?
Tags: ruby, programming
Published: 2023-02-17 16:30:08

## Ruby Symbols

I have come to appreciate the power and versatility of symbols in the language. In this guide, I will provide a comprehensive overview of symbols in Ruby, including their definition, usage, and best practices.

## Understanding Symbols in Ruby

In Ruby, a symbol is a class that is primarily used as an identifier. Although symbols may resemble strings and can be converted to them, they are not the same. Unlike strings, symbols are immutable and unique, making them ideal for use as method names, instance variable names, and keys in hashes.

## Immortal vs. Mortal Symbols

What you need to understand is that symbols are unique. And once they are created you will call the same one after. 
Before Ruby 2.2 Symbols were not Garbage Collected at all, after 2.2 it leads to the creation of 2 kind of symbols : 

- Immortal Symbols

- Mortal Symbols
 
### Mortal Symbols
Mortal symbols were first introduced after version 2.2 of Ruby, and they are automatically garbage collected once they are no longer in use. 
There are several ways to create symbols in Ruby, including the following:
```
#Called to_sym on a Strings
"mortal_symbol".to_sym
#Use Symbols literals
:"another_mortal_sym"
#Use interpolation this give => :mortal_sym2
:"mortal_sym#{1+1}" 
```

### Immortal Symbols
Immortal symbols are the original type of symbols in Ruby, and they are not garbage collected.So, it is important be careful when using them in order to prevent memory leaks. There are several ways to create immortal symbols in Ruby : 

```
#define a method dynamically with define_method
define_method(:immortal_method_sym) { puts "I am immortal" }
#define a instance variable with set_instance_variable
Object.instance_variable_set(:@a, "myvalue")
#creating a const using const_set
Object.const_set("MY_CONST","VALUE")

```
## Conclusion

In conclusion, symbols are an essential feature of the Ruby programming language that can greatly enhance the readability and performance of your code. By understanding the difference between immortal and mortal symbols and following best practices, you can use symbols to their full potential in your Ruby projects.

PS : Why I call this article " **Semiology** in Ruby " ? 
Semiology is the study of signs and symbols in a language and it really cool isn't it ?
Database Migrations with Go and Kubernetes

description: Database Migrations with Go and Kubernetes

Applications with database layer mostly need to execute database migration as part of its deployment process. Usually, running migrations is the first step when deploying the application.

I tried different tools to run migrations, I used [goose](https://github.com/pressly/goose) for a while, but later switched to [migrate](https://github.com/golang-migrate/migrate), which supports a lot of drivers and sources (you can save your migrations in S3 or Google Storage for example), also it has great CLI and Docker support.

Also, it feels very natural to containerize application migrations and tag Docker images with semver, so then we can run this container in our deployment pipeline.

If you're using Kubernetes there are multiple ways to run migrations before starting an application:

- Run container manually from your CD system (in this case you'll need to set up database access).
- Use Kubernetes Job and trigger it during the deployment.
- Use `initContainer` and run migrations before the main container starts.

I prefer the last options, as an application will always latest database snapshot, and also it will fail in case migrations are failing. Also, Kubernetes will help to make this process downtimeless for us.

Steps:

1. Prepare your migrations and store them in one of the available `migrate`'s sources (I will show an example with Google Storage)
2. Add `initContainers` section to your k8s deployment.

```yaml
initContainers:
  - name: migrations
    image: migrate/migrate:latest
    command: ['/migrate']
    args: ['-source', 'gcs://bucket/migrations', '-database', 'mongodb://mongo-0.mongo.default.svc.cluster.local:27017/db', 'up']
```

Now Kubernetes will run this container before starting the main pod. You will be able to see logs why migrations are failing.

Object-Oriented Programming in Python: A Comprehensive Guide
Tags: programming, oop, python, computerscience
Published: 2023-02-17 08:05:04

Object-Oriented Programming (OOP) is a programming paradigm that is used to design, create and modify software applications. Python is an object-oriented programming language and supports all the features of OOP.

## Introduction to Object-Oriented Programming

The basic idea behind object-oriented programming is to create an object that can be manipulated in a program. An object is a collection of data and associated behaviors that can be used to perform certain operations. In OOP, an object is an instance of a class. A class is a blueprint or a template for creating objects. It defines the data and behavior of the object.

## Classes in Python

In Python, classes are created using the keyword "class". The following is the syntax to create a class:

```
class ClassName:
    def __init__(self, arguments):
        self.variable_name = arguments
```
The `__init__` method is used to initialize the object's attributes. The self parameter is used to refer to the object itself. You can create any number of attributes and methods within the class.

## Inheritance

Inheritance is the process of creating a new class from an existing class. The new class is called the derived class or subclass, and the existing class is called the base class or superclass. The subclass inherits all the attributes and methods of the superclass.

## Polymorphism

Polymorphism is the ability of an object to take on many forms. In OOP, polymorphism means that a method can have different implementations in different classes. For example, the "+" operator can be used to concatenate strings, add numbers, and merge lists.

## Encapsulation

Encapsulation is the practice of hiding the internal details of an object and only exposing a public interface. It is achieved in Python by making the attributes and methods of an object private. The private attributes and methods can only be accessed within the class.

## Conclusion

Object-oriented programming is a powerful and flexible programming paradigm that is widely used in software development. Python provides full support for OOP and includes all the features of OOP, including classes, inheritance, polymorphism, and encapsulation. By using OOP, you can create well-organized and modular code that is easier to understand and maintain.
