Understanding Network services: FTP, SFTP, TFTP, NTP, DNS DHCP
Published: 2023-11-06 18:11:48

As a Cloud, DevOps Engineer, it is necessary to have a deep understanding of various network services that play a vital role in the infrastructure of cloud-based applications. This write-up will delve into some key network services: FTP, SFTP, TFTP, NTP, DNS, and DHCP. We will explore their functions and their significance in cloud environments.

## FTP (File Transfer Protocol)
Is a standard network protocol used to transfer files between a client and a server.
Users can upload or access files, organize their directories, and carry out basic file functions.

**Significance in Cloud DevOps:**
It is essential for migrating data to and from cloud storage

## SFTP (Secure File Transfer Protocol)
 Is a secure extension of FTP that uses an encrypted SSH connection for data transfer. It provides a more secure and reliable way to transfer files over a network

**Significance in Cloud DevOps:**
It is used for secure access to cloud-based storage and servers.

![SFTp](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/hpc4bf7b4bcv1xvxl5do.png)

## TFTP (Trivial File Transfer Protocol)
TFTP is a simplified version of FTP, primarily used for quickly transferring small files without the authentication and security features found in FTP or SFTP.

**Significance in Cloud DevOps:**
It supports the automation of cloud infrastructure deployment and configuration.

## NTP (Network Time Protocol)
NTP is a protocol used to synchronize the time of networked devices in a distributed and accurate manner.

**Significance in Cloud DevOps:**
NTP ensures that logs, metrics, and events generated by cloud resources are accurately timestamped, facilitating troubleshooting and incident response.

## DNS (Domain Name System)
DNS is used to translate human-readable domain names into IP addresses, making it possible for users to access websites and services by name.

> DNS enables users to access websites and services using domain names like "www.google.com" instead of IP addresses “192.22.3…”

**Significance in Cloud DevOps:**
It is used for configuring custom domains for cloud services and applications.

## DHCP (Dynamic Host Configuration Protocol)
DHCP is a network protocol that automates the assignment of IP addresses and other network configuration settings to devices on a network.

**Significance in Cloud DevOps:**
It supports the rapid scaling and deployment of cloud resources by automating IP address allocation.

## Conclusion 
Therefore, as a Cloud DevOps Engineer, one should have in-depth knowledge of such network services as FTP, SFTP, TFTP, NTP, DNS, and DHCP so as to guarantee the dependability, safety, and efficiency of cloud-based applications. Cloud service involves transfers, time synchronization, name resolution, and net configurations; all integral aspects of any modern cloud architecture. You should include those services in your DevOps practices to make your deployment process easier and operate your cloud resources smoothly.

I had a GeoCities site in the 90s and have hobby-coded since then. Up to now, I'm self-taught and I have no developer community. I don't know what I don't know, but I expect I could build cooler projects more quickly if I took some more formalized training and found some community. So I decided to sign up for a six-month night-class bootcamp that starts next month. I'm scared I'm not going to have enough time to devote to the class, already having a family and a fulltime job. I'm also afraid this is a silly investment: that I'm going to spend all this money and time and not get very much out of this. And anyways, what the hell am I going to do with basic developer skills when I already have an established career I enjoy? I don't know. But I'm excited to take a risk and dive in, learn some new things, make some new friends, and explore new possibilities.

Published: 2023-11-06 17:01:49

Hi Everyone

This is my first post here on DEV, although I was a little bit reluctant on taking an active role here on this community because I'm quite new into coding (I started in March) after watching some newbies being completely obliterated and humiliated on Stack Overflow 😅. 

I'm currently learning React and I have thousand of questions, but I would like to ask to more senior devs their opinion:

- Do you think react is going to be around in the next 10 years?

- What other library/framework would you strongly recommend me to focus on?

I thank you in advance you insights and your inputs.

How to Check if Your Android Device Has a Widevine License
Tags: widevine, license, drm, android
Published: 2023-11-06 16:38:54

# Introduction

We all know that streaming movies and TV shows is an increasingly popular activity, but do you know how to check if your Android device has a Widevine license? Widevine is a digital rights management (DRM) platform that is used by many streaming services, including Netflix and Amazon Prime Video. It ensures that the content you’re streaming is protected from being pirated or copied. In this blog post, we’ll explore what a Widevine license is, how to check if your Android device has one, and why it’s important.

# What is a Widevine License?

A Widevine license is a digital certificate that allows a device to access content that’s been encrypted with Widevine DRM. It ensures that the content is only accessible on the device that has the license, and that it can’t be copied or distributed illegally. The license is also used to check if the device has the necessary hardware and software requirements to stream the content.

# How to Check if Your Android Device Has a Widevine License

To check if your Android device has a Widevine license, open the Google Play Store and search for “Widevine DRM”. If the app is available for your device, it means that it has the necessary license. If not, you can try downloading the app from other third-party sources, but be sure to only download from trusted sources.

# Why is it Important to Have a Widevine License?

Having a Widevine license is important because it ensures that the content you’re streaming is protected from piracy. It also ensures that the content is only accessible on the device that has the license, and that it can’t be copied or distributed illegally. It also ensures that the device has the necessary hardware and software requirements to stream the content.

# Conclusion

In conclusion, it’s important to check if your Android device has a Widevine license. A Widevine license is a digital certificate that allows a device to access content that’s been encrypted with Widevine DRM. It ensures that the content is only accessible on the device that has the license, and that it can’t be copied or distributed illegally. To check if your Android device has a Widevine license, open the Google Play Store and search for “Widevine DRM”. If the app is available for your device, it means that it has the necessary license. We hope this blog post has been helpful in understanding what a Widevine license is, how to check if your Android device has one, and why it’s important.
Capture IP address using Bun with ElysiaJS, Docker and Render.com
Tags: webdev, javascript, tutorial, programming
Published: 2023-11-06 16:38:54

In this tutorial, I'll walk you through creation of an app, which for demonstration purposes, reveals the IP address of visitors. The app is built using [Bun](https://bun.sh), [ElysiaJS](https://elysiajs.com), and [Render](https://render.com). By the end, you'll have a setup to fetch and display users' IP address in your web application.

## Installing Bun runtime & toolkit

Cherry picked from [Bun](https://bun.sh) itself, Bun is an all-in-one JavaScript runtime & toolkit designed for speed, complete with a bundler, test runner, and Node.js-compatible package manager.

In short, it's everything as is in the Node.js ecosystem, just with faster and good defaults (lots of work is being done on improving it each day).

Let's begin by installing the Bun, which we'll use to manage our project:

```bash
curl -fsSL https://bun.sh/install | bash
```

> Supported on macOS, Linux, and WSL.

## Using Render's template to use Bun runtime

[Render](https://render.com) is a cloud platform for deploying web applications. We'll utilize their pre-baked Bun template to make the most of the Bun runtime. It was flawless to use Bun runtime with [Render](https://render.com) (say instead of [Vercel](https://vercel.com), for example).

```bash
git clone https://github.com/render-examples/bun-docker
```

## Installing Dependencies

Ensure you install all the necessary dependencies for your project:

```bash
bun install
```

## Installing ElysiaJS

Next, we'll use ElysiaJS into our project. 

[ElysiaJS](https://elysiajs.com) is a lightweight web framework for TypeScript, making it easier to handle HTTP requests and responses using Bun! Think of it like [express](https://expressjs.com) but for Bun.

```bash
bun install elysia
```

## Building Your Application

Update your `app.ts` with your the code to display the IP Address of the users visiting the website. In this example, we're returning a response header that includes the user's IP address.

```typescript
// File: app.ts

import { Elysia } from "elysia";

new Elysia()
  .head('/', ({ set }) => {
    set.status = 200
  })
  .get("/", ({ request, set }) => {
    set.status = 200
    return request.headers.get('true-client-ip')
  })
  .listen(3000)
```

With these steps, you'll be able to capture and display the IP addresses of visitors to your web application. This can be valuable for various purposes, including security, analytics, and personalization.

## You're Done

In this guide, we've walked through the process of capturing users' IP addresses with the Bun Runtime, ElysiaJS framework, and Render deployment platform.
Polyfills for .forEach(), .map(), .filter(), .reduce() in JavaScript
Published: 2023-11-06 16:34:35

ForEach:
```js
function print(i){
console.log(i)
}
const names = ["ali", "hamza", "jack"];
Array.prototype.myForEach = function(cb){
  console.log(this)
  for(let i=0; i<this.length; i++){
    cb(this[i])
  }
}

names.myForEach(print);
```

Map:

```js
function multiplier(element) {
  return element * 2
}

let arr = [1, 2, 3];

Array.prototype.myMap = function (cb) {
  let newarr = [];
  for (let i = 0; i < this.length; i++) {
    newarr.push(cb(this[i]))
  }
  return newarr
}

let result = arr.myMap(multiplier);
console.log(result)

```
Filter
```js
function filter(element) {
  return element > 1
}

let arr = [1, 2, 3];

Array.prototype.myFilter = function (cb) {
  let newarr = [];
  for (let i = 0; i < this.length; i++) {
    if(cb(this[i])){
      newarr.push(this[i])
    }
    
  }
  return newarr
}

let result = arr.myFilter(filter);
console.log(result)

```

Reduce

```js
function sum(accumulator, element) {
  return accumulator + element;
}

let arr = [1,1,1,1,1,1,1,1,1];

Array.prototype.myreduce = function (cb, initialValue) {
  let accumulator = initialValue ? initialValue : undefined;

  for(let i=0; i<this.length; i++){
    if(accumulator !== undefined){
      accumulator = cb(accumulator, this[i])
    }else{
      accumulator = this[i]
    }
  }
 
  return accumulator
}

let result = arr.myreduce(sum);
console.log(result)

let result2 = arr.myreduce(sum, 10);
console.log(result2)

AWS architecture for an e-commerce platform
Tags: aws, alx, sandtech, alxcloudcomputing
Published: 2023-11-06 16:10:47

Last Thursday at our ALX expert session we were given a use case for an e-commerce platform.

Use case:
An e-commerce business has contacted you to draw up an architectural design for their new portal for their customers in Africa. They want to ensure their application has very low latency, can also store their user relational information securely, and is also able to be retrieved fast.

The portal is expected to store some pictures of products. The business also wants to ensure its application is fault-tolerant and highly available.

Although they are low on budget, they also want to ensure their application is highly secured, both at rest and in transit, and from unauthorized access. You should also factor in monitoring and logging your application.

My architecture design and solutions:
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/quehep0q1a1vegbdnkwt.png)`

Based on the requirements given we can notice some keywords. For example, this platform serves African customers which implies we should choose a region in Africa (South Africa region) to achieve low latency. We should also use CloudFront, ElasticCache, and Network Load Balancer for low latency. To ensure high availability and fault tolerance we can use a multi-az infrastructure with ec2 instances in an auto-scale group. To store pictures in a cost-optimized and highly-available way we can use s3. Security is one of the top priorities when we design any infrastructure we secure our system from unauthorized access with Cognito and we secure our data at rest and transit with KMS and Certificate Manager respectively lastly we monitor and log our system using CloudWatch and CloudTrail. 

Thank you for reading and open to suggestions and improvement!

C# - Singleton Design Pattern with Lazy Initialization
Tags: csharp, programming, tutorial
Published: 2023-11-06 15:30:00

The Singleton design pattern ensures that a class has only one instance and provides a global access point to that instance. In C#, you can implement a Singleton pattern using lazy initialization for efficient resource usage. Here's an example of how to do it:

```csharp
using System;

public class Singleton
{
    private static readonly Lazy<Singleton> instance = new Lazy<Singleton>(() => new Singleton());

    // Private constructor to prevent instantiation from other classes.
    private Singleton()
    {
        Console.WriteLine("Singleton instance created.");
    }

    // Public static method to access the Singleton instance.
    public static Singleton Instance => instance.Value;

    public void SomeMethod()
    {
        Console.WriteLine("Singleton method called.");
    }
}

class Program
{
    static void Main()
    {
        // Access the Singleton instance
        Singleton singleton1 = Singleton.Instance;
        Singleton singleton2 = Singleton.Instance;

        // Verify that both instances are the same
        Console.WriteLine($"singleton1 == singleton2: {singleton1 == singleton2}");

        // Use the Singleton
        singleton1.SomeMethod();
    }
}
```

In this example:

1. We define a `Singleton` class with a private constructor, preventing direct instantiation from other classes.

2. We use `Lazy<T>` to ensure lazy initialization of the Singleton instance. This means that the instance is created only when it is first accessed, improving performance and resource usage.

3. The `Instance` property provides a static way to access the Singleton instance.

4. In the `Main` method, we demonstrate that two calls to `Singleton.Instance` result in the same instance being returned, confirming that it's indeed a Singleton.

Implementing the Singleton pattern with lazy initialization ensures thread safety, minimizes resource usage, and provides a single point of access to a shared instance, making it a valuable design pattern in many scenarios, such as managing application configuration, logging, and caching.
Advanced Typography: Using OTF Font Features in Android
Tags: android, tutorial, programming
Published: 2023-11-06 15:25:00

When it comes to typography, there’s more to it than just choosing between medium and semibold font weights. Modern OpenType fonts come packed with a variety of advanced font features that allow for a more sophisticated and visually stunning typographic experience.

These features, ranging from ligatures to contextual alternates and beyond, offer designers and typographers greater control over how text is displayed, resulting in more creative and expressive typography. Whether working on a design project or simply trying to make your text stand out, these font features are essential for achieving the best possible results.

Please note that the features mentioned are only available in OpenType fonts. Therefore, the font file you use must have .otf extension. Additionally, font features and their names may differ from font to font. Not all fonts may support the feature you are looking for.

To provide a clear example, I will be using Inter font, which is widely used and has detailed documentation. The following image illustrates ss01 and ss02 features of the font.

![Image taken from https://rsms.me/inter/](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/5m2j84tfzfk7j3cgly24.png)

After adding the OTF file to /res/font folder, we need to set the attribute to use features. If we don’t modify the features, the font will be presented in its default settings.

We need to set the attribute as in the example:

```
<TextView
  tools:text="Placeholder text"
  android:fontFeatures="ss01" />
```

And, when you want to combine features, separate the feature names with commas as in the example:

```
<TextView
  tools:text="Placeholder text"
  android:fontFeatures="ss01, ss02" />
```

But where are those abbreviations coming from? When you visit the lab, you’ll see a section named features in the sidebar. There, you can play with any features you like and see the results of the change on the left side. The feature names are also given there for reference.

And there you go. This is an example of how you can do advanced text styling in TextView.
