Simplify Your Build Process with XC Tasks
Tags: webdev, programming
Published: 2023-05-15 23:51:32

## Overview

XC is a great tool I've been using to document build steps in the readme and simplify the build process. It is easy to integrate and simplifies the code management workflow. Here I'll cover how to use XC Tasks for your projects.

XC Tasks Github Repository: [https://github.com/joerdav/xc](https://github.com/joerdav/xc)

## Main Build, Push, and Test Environment

With XC Tasks, I have created a task called `main-build-push-test-env` which builds, tags, and pushes the Docker image to the remote registry. Additionally, it deploys the application with Caprover.

The main-build-push-test-env task requires executing these four subtasks:

1. build-test-image
2. tag-test-image-remote
3. push-test-image-remote
4. caprover-deploy-test

## Building and Tagging Docker Images

### 1. Build the Docker Image

The `build-test-image` task builds the Docker image using the `docker build` command:

```sh
docker build --pull --rm -t image-name:latest .
```

### 2. Tag the Local Image with the Remote Name

The `tag-test-image-remote` task tags the locally built image with the remote registry name:

```sh
docker tag image-name:latest $REGISTRY_ADDRESS/image-name:latest
```

## Pushing Docker Images to Remote Registry

### 3. Push the Local Image to the Remote Registry

The `push-test-image-remote` task pushes the tagged local image to the remote registry:

```sh
docker push $REGISTRY_ADDRESS/image-name:latest
```

## Deploying the Application with Caprover

### 4. Deploy the Application using Caprover

The `caprover-deploy-test` task deploys the application to Caprover using the `caprover deploy` command:

```sh
caprover deploy --imageName $REGISTRY_ADDRESS/image-name:latest
```


## Syntax

The syntax that XC is looking for might look something like this at the end of your README.md file: You can see the raw syntax [here](https://gist.githubusercontent.com/IzzleNizzle/2bd482f21086c3c4f866daff34b52555/raw/adb0f60e9f7842a6fc291802e3500ae9c1205b28/XC%2520Tasks%2520Syntax%2520Example.md)


## Conclusion

By using XC Tasks to simplify the build process, you only need to maintain the tasks definitions in your readme file, rather than remembering the process or maintaining multiple scripts. This streamlined approach will help you efficiently manage your deployment pipeline while ensuring that your application remains up-to-date and properly deployed.
First Post
Published: 2023-05-15 23:33:02

Hello World! With that out of the way, this is simply my first post to help document my progress as I teach myself the fundamentals of software engineering. Today I actually had a small win. I was able to finally publish my first completed project from Frontend Mentor using GitHub Pages! For whatever reason I struggled a lot with that simple thing and it was only after reading a tutorial did I realize my problem could be solved by simply changing the visibility setting on my project from private to public. Unfortunately, after having published it, I saw that the image was not showing like it was supposed to so I will have to go back and figure out why. Until next time!

What type of College Degree is Necessary for using Reddit today?
Tags: reddit, ux, complexity, problem
Published: 2023-05-15 23:19:47

**This is most complicated network I have been used out there!**. 

Whatever I try there, there is one error for everything. Trying to post simple title text and with or without link and it will just show some universal error without any clue what did you made wrong here. This can be so frustrating!

Also, crossposting feature. Like this subreddit don’t allow images or link or whatever. Why then we dont have options there to update that post in a place? 

I am not so new here I made profile before 7 years bit never used so much probably because all of this tricks which can kill your motivation for using it.

Also, definitely cant say that I am an ignorant, I have built social networks by myself before and I have accounts on almost every top social network and still Reddit is really too complicated. At some point it looks like it is full of errors, because nobody can tell me that those universal errors cant provide more concise message?

I think there should be really great tutorial for using Reddit, if there is no any already? I didn’t check. 
But somehow I think this is a full of errors, because of that its not possible to make a good tutorial.

However, let me try to use it more in the next few days. After all maybe its about me and maybe Reddit really has it own logical rules not so easy for understanding it in a fast way.

REVERSE ENGINEERING
Tags: webdev, beginners, productivity
Published: 2023-05-15 23:16:40



Introduction:
Imagine you have a magical object in your hand, but it doesn't come with any instructions. You're curious about how it works, so you decide to become a detective and uncover its hidden secrets. This process of discovering the mysteries behind something is called "reverse engineering." In this article, we'll embark on an exciting journey to understand what reverse engineering is and how it can be useful in the world of technology.

What is Reverse Engineering?
Reverse engineering is like being a detective who tries to solve a mystery by taking things apart and examining them closely. Instead of starting from scratch to build something, we take an existing thing and figure out how it was made or how it works. It's like taking apart a toy to understand how it functions.

Why Do People Reverse Engineer Things?
People reverse engineer things for different reasons. Sometimes, they want to understand how something works to make it better or fix it if it's broken. Other times, they want to create something similar or find out how to protect against potential dangers. It's like looking at a blueprint to understand how a building was constructed.

Examples of Reverse Engineering in Everyday Life:
Reverse engineering is not just for technology wizards; it happens in our everyday lives too! Here are a few examples:

Puzzle-solving: Have you ever tried to solve a Rubik's Cube? By twisting and turning the cube, you're actually reverse engineering its puzzle to understand how to get all the colors in the right place.

Recipes: When you want to bake a delicious cake, you may follow a recipe. That recipe is like reverse engineering, as it tells you the step-by-step process to recreate a mouthwatering treat.

Reverse Engineering in Technology:
In the world of technology, reverse engineering plays a crucial role. Here are some examples:
Software: Imagine there's a cool app that you love, but you want to understand how it was made. By reverse engineering the software, programmers can learn from it, create similar apps, or fix any bugs they find.

Hardware: Think about a smartphone. Reverse engineering allows engineers to take it apart, examine its components, and understand how everything works together. This knowledge helps in making improvements or creating new and exciting gadgets.

The Ethics of Reverse Engineering:
While reverse engineering can be exciting, it's important to remember the importance of ethics. It's like being a detective with a moral compass. We need to respect the original creators' hard work and follow legal guidelines to ensure we're using reverse engineering for good purposes.
Conclusion:
Reverse engineering is an adventure that allows us to unravel the secrets behind the things we see and use every day. Whether it's understanding how a toy works or exploring the inner workings of technology, reverse engineering gives us a deeper understanding of the world around us. So, next time you encounter a mysterious object, remember that you have the power to become a detective and discover its hidden wonders through reverse engineering!.

No projeto pessoal, comecei hoje. O projeto é uma página principal simples de alguns produtos, ja apliquei e estilizei o Header e o Body até agora, usando o ReactJS, aplicando o que vi no curso.
Easy & Secure pre-signed URL for file access
Tags: aws, googlecloud, azure, cloudcomputing
Published: 2023-05-15 22:48:39

A pre-signed URL is a valuable tool for providing temporary, controlled access to specific resources within a storage service, such as Amazon S3 or Google Cloud Storage. 

By using pre-signed URLs, you can grant limited access to users without giving them full permissions to your storage account, set expiration times to automatically revoke access, reduce the server load by allowing direct access to resources, simplify authentication, and improve audibility and tracking of resource usage. 

Setting one up with the Nitric framework is a breeze.

```
import { bucket } from '@nitric/sdk';

const assets = bucket('assets').for('reading', 'writing');

const logo = assets.file('images/logo.png');

// Create a read-only signed url reference for downloading
const downloadUrl = await logo.getDownloadUrl();

```

See fully functional examples exposed via an API in [typescript](https://github.com/nitrictech/example-apps/tree/main/upload-secure-url/typescript) and [python](https://github.com/nitrictech/example-apps/tree/main/upload-secure-url/python).

_liner notes_:
- Saturday : Headed out to the city earlier than normal to go to a few stores looking for a specific type and color of shirt for an outfit I'm putting together for an upcoming event. I went to like 5 different stores and it was the last one where I found something that could work. Then I headed to the station and we did the radio show. Had a great time as usual. The recording of this week's show is at https://kNOwBETTERHIPHOP.com

- Sunday : Pretty productive day. In addition to the stuff I normally do, I created and published a new Web Component that I'll be using in an upcoming presentation. Also researched and ordered some more things for the outfit I'm putting together. I think I may have everything.

- Professional : Started off the week pretty strong. Followed up on a couple of messages. Fleshed out a blog post I've been working on. I'll look it over again tomorrow, make any changes if needed and then submit it for review. Also, worked on the demo that goes along with it.

- Personal : I took a break from my current side project to work on the platform I made to do my presentations. I want to try something new so I'll have to make some changes to accommodate the new functionality. I've got a plan. Let's see if I'm right.

Going to see if I can get the platform I created refactored to work with the new functionality I want to implement. Like I said, I've got a plan. haha.

Have a great night!

OSDC-2023-assignment6&7 -Docker
Tags: osdc, github, python, docker
Published: 2023-05-15 22:28:12

In lessons 6 and 7, we learn about [docker](https://www.docker.com/get-started/).
We reviewed what a "Docker" image is and saw how to set up a development environment with its help.
We went over the slides of [Learning Linux in a Docker container](https://code-maven.com/slides/linux-docker/) up before the slide about CentOS.
and also we saw examples of [Open source project in Docker](https://code-maven.com/slides/docker/open-source).

my favorite language is python, so I develop with it.

All package that I fix something i chose from [pydigger](https://pydigger.com/) this site Leads to libraries where things need to be fixed, for example they lack author,vcs or ci.

Setting up a development environment via Docker :

1. Make sure you have Docker installed on your machine:
[Docker](https://docs.docker.com/get-docker/).

2.  for package [django-autotask](https://github.com/KerkhoffTechnologies/django-autotask):  

```
 git clone git@github.com:KerkhoffTechnologies/django-autotask.git
    cd django-autotask
    docker build -t django-autotask .
    docker run -it --name my-django-autotask-container django-autotask /bin/bash
```

link to my [PR](https://github.com/KerkhoffTechnologies/django-autotask/pull/206/files)

for package [sankaku](https://github.com/zerex290/sankaku)

```
git clone https://github.com/zerex290/sankaku.git
cd sankaku
docker run -it --name sankaku -w /opt -v$(pwd):/opt python:3.11 bash
```

link to my [PR](https://github.com/zerex290/sankaku/pull/1)

some of packages I add fix of installs that was missing like here Or missing code that is will me more clearly:
1. [edx-arch-experiments](https://github.com/edx/edx-arch-experiments)
My [PR](https://github.com/edx/edx-arch-experiments/pull/296/files)
2. [cortex-python](https://github.com/CognitiveScale/cortex-python)
My [PR](https://github.com/CognitiveScale/cortex-python/pull/174)
3. [deep_sort_realtime](https://github.com/Cranfield-GDP3/deep_sort_realtime)
My [PR](https://github.com/Cranfield-GDP3/deep_sort_realtime/pull/1)

I learned a lot from the lessons:
1.Run containers in Docker
2. You don't have to be afraid to send PR, in the worst case you don't receive them.
3.perform tests on scripts

Thanks to [Gabor](https://he.code-maven.com/) that makes the world a better place.

How to Cache in Node.js Application
Tags: webdev, javascript
Published: 2023-05-15 22:06:36

# How to Cache in Node.js Application

Caching is a technique used to store frequently accessed data in memory, so that it can be retrieved quickly without having to fetch it from the source every time. Caching can significantly improve the performance of your Node.js application, especially if it involves frequently accessed data.

There are several ways to implement caching in a Node.js application. In this article, we will explore some of the most popular methods.

## In-Memory Caching

In-memory caching is the simplest form of caching. It involves storing data in memory, which can be accessed quickly without having to fetch it from the source every time. In Node.js, you can use a package like `node-cache` or `memory-cache` to implement in-memory caching.

Here's an example of how to use `node-cache`:

```javascript
const NodeCache = require('node-cache');
const cache = new NodeCache();

// Set a key-value pair in the cache
cache.set('myKey', 'myValue');

// Get the value for a key from the cache
const value = cache.get('myKey');
console.log(value); // Output: myValue
```

## Distributed Caching

Distributed caching involves storing data across multiple servers, so that it can be accessed quickly from any server. This is useful for applications that are deployed across multiple servers, or for applications that need to handle a large amount of traffic.

In Node.js, you can use a package like `redis` or `memcached` to implement distributed caching.

Here's an example of how to use `redis`:

```javascript
const redis = require('redis');
const client = redis.createClient();

// Set a key-value pair in the cache
client.set('myKey', 'myValue');

// Get the value for a key from the cache
client.get('myKey', (err, value) => {
  console.log(value); // Output: myValue
});
```

## Caching HTTP Responses

Caching HTTP responses can significantly improve the performance of your Node.js application, especially if it involves frequently accessed data. In Node.js, you can use a package like `express-cache-controller` or `http-cache-middleware` to implement caching of HTTP responses.

Here's an example of how to use `express-cache-controller`:

```javascript
const express = require('express');
const cacheController = require('express-cache-controller');
const app = express();

app.use(cacheController({
  maxAge: 60 // Cache for 60 seconds
}));

app.get('/my-route', (req, res) => {
  // Generate the response
  const response = { message: 'Hello, world!' };

  // Send the response
  res.json(response);
});
```

## Conclusion

Caching is an important technique to improve the performance of your Node.js application. In this article, we explored some of the most popular methods of caching in Node.js, including in-memory caching, distributed caching, and caching of HTTP responses. By implementing caching in your Node.js application, you can significantly improve its performance and scalability.
5 Dicas que te ajudam a nomear variáveis em JavaScript
Tags: javascript, beginners, programming
Published: 2023-05-15 22:02:20

Variáveis ​​são caixas em Javascript que facilitam muito a vida do código para o programador ler… quando escritas de maneira conveniente. Aqui vou listar de maneira breve algumas convenções que uso e acredito que sejam úteis à comunidade JS. ✌


![Foto de Milad Fakurian no Unsplash](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/507z2k97j12srvnwopaf.jpg)

Antes de tudo lembre-se que:

- Variáveis ​​em JS diferenciam letras minúsculas e maiúsculas.
- Não há limites para o comprimento de uma variável. (Mas vamos com calma hein rs)
- O primeiro caractere deve ser uma letra ou um sublinhado. Não pode usar número com primeiro caractere!
- O restante do nome da variável pode ser letra, número ou sublinhado. Qualquer caractere diferente disso não pode.
- E por último há como todas as linguagens palavras reservadas que não podem ser usadas, se não geram confusões ou problemas maiores 🤯 no código.

Terminado essa explicação vamos às dicas:

1 - **Uma variável JavaScript deve ser autodescritiva**.

Talvez essa seja a dica mais trivial de todas, afinal, desde pequenos sabemos o que são animais, frutas, números… então conhecer os conjuntos a que pertence a variável acaba sendo um conhecimento de vida.

2 - **Um prefixo como is , are ou has em um booleano.**

Ajuda todo desenvolvedor JavaScript a distinguir o verdadeiro/falso na hora!
```
// ruim:
let visible = true;
// bom:
let isVisible = true;
// ruim:
let encryption = true;
// bom:
let hasEncryption = true;
```
3 - **Constantes em letras MAIÚSCULAS.**

As constantes são as variáveis que nunca mudam, apenas sofrem adendo.

```
var SEGUNDOS = 60;
var MINUTOS = 60;
var HORAS = 24;   
var DIA = SEGUNDOS * MINUTOS * HORAS;  
```

4 - **Sublinhados para externos/terceiros.**

Ocasionalmente, você encontrará sublinhados na variável ao obter informações de terceiros, como bancos de dados ou APIs.

5 - **Evite o traço.**

Não é senso comum. Mas traço torna as coisas mais difíceis…

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/j0y66hkkenfqr8ond343.png)
Não é possível nem declarar uma variável com traço.

How to Center a Background Image Inside a Div Using CSS
Tags: webdev, css, programming, html
Published: 2023-05-15 21:12:49

In this article, we’ll see how to use CSS properties such as background-size and background-position to center a background image within a div.

**CSS Properties:**

**Background-Size:** The ‘background-size’ CSS property enables scaling of background images to fit available space by adjusting their dimensions.
**Background-Position:** The CSS background-position property is used to specify where the background image should be placed. This property is used to position the background.

**Syntax:**

`background: url() no-repeat center;`

**Example 1**: In the following example, we use first use the background URL to get the image from the web then we set no-repeat and center after that we set the width to 100% and height of 200px last use the background-size to 350px.

```

**Example 2:** The “container” div has a centered background image, set with “background-position” and “url()” with “no-repeat”. Use “background-size: cover” to fill the div and “background-position: center” to center it. Set “width: 100%” and “height: 500px” for full coverage. To center the “h1” element, use “display: flex; justify-content: center; align-items: center;”.
