Flutter vs ReactNative, which and why?

Saber Hosney — Tue, 29 Jun 2021 17:06:10 +0000

Greetings!
I hope you all still having a good day in this hot summer xd

What I'm trying to achieve in the short term?
An app that help customers contacts us and viewing their tickets.

What I'm looking for in the long term?
Something that integrates well with the tools we already use e.g
Firebase.

Why considering Flutter?
Flutter seems a decent choice since you can use Android/iOS-like components and the out-of-the-box support for firebase.

Why considering ReactNative?
We have used a similar tools before like VueJS. Also The syntax looks easier to me :D

I would like to know your opinions and recommendations, Thank you!

Opinions on which to pick C++ or Java for GUI project?

Saber Hosney — Sun, 01 Mar 2020 15:11:45 +0000

Hey fellow Devs!

So here the thing I'm currently enrolled in ComputerScience degree in University.

Basically this semester I will have to make a project with this limitations :

Must have a GUI.
Implement at least one of the Search and Sort algorithms.
Must be written in one of the following : C#, C++ or Java.

after some search here and there I found this answer

answer re: GUI with C++ ? or C# and Java the way to go?

First of all, if you want to lean to write platform independent GUI then C# is no go.

When you write GUI in C++ there is a question of toolkit, Qt and GTKmm provide you very solid cross platform toolkits. While Qt has more "native" look and feel on Windows…

Open Full Answer

this answer is quite old and the release of DotNet Core made possible to create cross-platform apps using C#, but I'm dropping C# because I feel like C++ is more powerful somehow and I have basic understanding of it(I rate myself as above beginner in C++) I feel a bit comfortable with it, also I'm considering Java even that I will have to learn it first, because most of the internet says it's the best choice for enterprise-level apps (I'm not sure what Enterprise-level means :D) but if I learned it will be more helpful in the future right?

One last thing, If I'm gonna use C++, I will learn and be using the Qt framework, I tried my luck with other ones but mostly fail not sure because that I run on windows or the lack of information on how to use 'em .

Working with custom exceptions in namespaced files

Hello fellow devs !
today I came across a situation where I need to use Exceptions within a namespaced project, It was either I use the global namespace \Exception or I create a custom one. And of course we wouldn't be reading this if I choose the former :", Okay enough chat, let's dig in !

Assuming that you are familiar with composer autoload

let's create our namespaced class checker.php

<?php
namespace SHD;
class Checker
{
    public function checkPalindrome($text){
        $text = preg_replace('/[^A-Za-z0-9]/', '', $text);
        $text = strtolower($text);
        $before = $text;
        $after = strrev($text);
        if ($before == $after){
            echo "Wow, you can read this text correctly from both ways";
        } else {
            echo "This text isn't a palindrome!";
        }
    }
}
?>

now let's try using it in index.php

<?php
//Composer autoload
require 'vendor/autoload.php';
//Loading the class and create new instance
use SHD\Checker as Checker;
$checker= new Checker;
//Performing our actions
echo $checker->checkPalindrome("A man, a plan, a canal – Panama");
?>

So far so good, right ? lets tweak the above code to create our custom exceptionchecker.php

<?php
namespace SHD;
//Loading our custom Exception Class
use SHD\Exception;
class Checker
{
    public function checkPalindrome($text){
        //previousCode
        try {
            if ($before == $after){
                echo "Wow, you can read this text correctly from both ways";
            } else {
                throw new palindromeException("Not valid palindrome", 4);
            }
        } catch (palindromeException $e) {
            echo $e->showError();
        }
    }
}
?>

exception.php file where the custom exceptions are!

<?php

namespace SHD;
//Loading global exception is a must before it can be extended
use Exception;
class palindromeException extends Exception
{
//This code is required to make the exception code and message not optional
    public function __construct($message, $code, Exception $previous = null) {
//Passing 'em to the Exception calss itself
        parent::__construct($message, $code, $previous);
    }
//Our custom method
    public function showError(){
        $error = $this->message;
        if ($this->code == "4") {
            $error = $this->code .":".$this->message;
        }
        return $error;
    }
}

?>

All done, now back to index.php and change the sentence a bit to trigger the exception and watch your hard work pays off

Maybe most of you (lovely readers who reached this point of the article) already knew this, but for people like me who struggles with such easy tasks, this will be a quick reference.
Thank you all for reading <3
