In simple terms, websockets are an upgrade to traditional HTTP.
Websockets are mostly used at places where real time updates are necessary. For example:
Function chunk dan cursor ini digunakan untuk get data besar, untuk meminimalkan penggunakan memory ram
Perbandingan performance :
We have a comparison: chunk() vs cursor()
10,000 records:
+-------------+-----------+------------+
| | Time(sec) | Memory(MB) |
+-------------+-----------+------------+
| get() | 0.17 | 22 |
| chunk(100) | 0.38 | 10 |
| chunk(1000) | 0.17 | 12 |
| cursor() | 0.16 | 14 |
+-------------+-----------+------------+
100,000 records:
+--------------+------------+------------+
| | Time(sec) | Memory(MB) |
+--------------+------------+------------+
| get() | 0.8 | 132 |
| chunk(100) | 19.9 | 10 |
| chunk(1000) | 2.3 | 12 |
| chunk(10000) | 1.1 | 34 |
| cursor() | 0.5 | 45 |
+--------------+------------+------------+
Secara kesimpulan seperti ini :
Therefore, when processing a large amount of data, it seems better to use cursor () when speed is prioritized, and chunk () when memory usage does not exceed a certain value.

Over-fetching is fetching too much data, meaning there is data in the response you don’t use.
Under-fetching is not having enough data with a call to an endpoint, forcing you to call a second endpoint.

PHP is a popular programming language used by many websites and web applications. It is important to keep track of the different versions of PHP as they can affect the compatibility of your code and the functionality of your website. In this article, we will discuss how to manage PHP versioning on a Macbook.
One option for managing PHP versioning on a Macbook is to use the ASDF (Another Version Manager) tool. ASDF allows you to easily switch between different versions of PHP, as well as other languages such as Ruby and Python. To install ASDF, follow the instructions on the ASDF website or refer to the tutorial by Tim Nash.
Another option is to use the PHPBrew tool, which allows you to install and manage multiple versions of PHP on your Macbook. To install PHPBrew, follow the instructions on the PHPBrew website or refer to the tutorial by GetGrav.
Once you have installed either ASDF or PHPBrew, you can easily switch between different versions of PHP by using the appropriate command. For example, with ASDF, you can use the command “asdf global PHP [version]” to switch to a specific version of PHP. With PHPBrew, you can use the command “phpbrew switch [version]” to switch to a specific version of PHP.
It is important to note that you may need to update your Apache configuration in order to use a different version of PHP. This can be done by modifying the “LoadModule” and “AddType” lines in the Apache configuration file. Refer to the Apache documentation or a tutorial such as the one by GetGrav for more information on this process.
In summary, managing PHP versioning on a Macbook can be easily done using tools such as ASDF or PHPBrew. These tools allow you to easily switch between different versions of PHP, ensuring that your code is compatible and your website is functioning properly. Be sure to also update your Apache configuration if necessary in order to use a different version of PHP.

Framework NodeJs rasa Laravel
Framework ini bisa terbilang sangat baru, dan dibuat sangat penasaran, karna katanya framework ini sangat mirip dengan framework Laravel
Topik kali ini, kita hanya akan melakukan
Pertama install dulu AdonisJs cli lewat terminal
npm i -g @adonisjs/cli
kalau sudah berhasil, tinggal bikin applikasi web dari Adonis
adonis new name_application
lalu masuk ke directorynya
dan jalankan applikasi web kita dengan command adonis server — dev
cd name_application
adonis serve --dev
sekarang tinggal buka browser dan akses localhost atau 127.0.0.1 dengan port 3333
http://localhost:3333
Viola, kita sudah berhasil membuat applikasi pertama dengan adonis dan menjalankannya di browser
dari struktur foldernya bisa dikatakan sangat mirip dengan laravel
feel like home, buat developer laravel mau mencoba framework NodeJs

Install dengan menggunakan composer secara global
composer global require laravel/envoy
Menambahkan alias composer dari variabel $PATH
Tambahkan di zsh profile ~/.zshrc
export PATH="$HOME/.composer/vendor/bin:$PATH"

sekarang penggunakan polymorph laravel, untuk type pasti berbentuk string
untuk indexing string emang mengurangi performance database itu sendiri
seperti sumber dari twitter berikut
When using Laravel morphs, you can eek out some extra performance by using small integers instead of strings for your morph types.
Smaller, faster indexes for the database to manage!
Especially useful for tables like comments or audits, which can be many millions of rows. pic.twitter.com/vZZluD5dod

Envoy adalah alat yang dikembangkan oleh Laravel yang memungkinkan Anda menjalankan perintah server langsung dari aplikasi Laravel Anda. Ini sangat berguna ketika Anda ingin menjalankan tugas-tugas seperti deployment atau migrasi database tanpa harus menggunakan ssh ke server.
Untuk menggunakan Envoy, Anda harus menambahkan file bernama Envoy.blade.php
Berikut adalah contoh konfigurasi Envoy untuk proyek Laravel:
@servers(['web' => '[email protected]']) @task('deploy', ['on' => 'web']) cd /var/www/my-project git pull origin master php artisan migrate @endtask @task('rollback', ['on' => 'web']) cd /var/www/my-project git revert HEAD php artisan migrate:rollback @endtask
Di sini, kita telah menentukan server dengan nama web yang diakses melalui user user dan IP 192.168.10.10. Kemudian, kita telah mendefinisikan dua tugas, yaitu deploy dan rollback. Tugas deploy akan menjalankan perintah git pull untuk mengambil revisi terbaru dari repository, kemudian menjalankan perintah php artisan migrate untuk menjalankan migrasi database. Tugas rollback akan menjalankan perintah git revert untuk mengembalikan revisi sebelumnya, kemudian menjalankan perintah php artisan migrate:rollback untuk mengembalikan database ke revisi sebelumnya.
Untuk menjalankan tugas ini, Anda hanya perlu menjalankan perintah envoy run deploy atau envoy run rollback di terminal. Envoy akan mengakses server yang telah ditentukan dan menjalankan perintah-perintah yang telah ditentukan di file Envoy.blade.php.
Dengan menggunakan Envoy, Anda dapat dengan mudah menjalankan perintah server dari aplikasi Laravel Anda, sehingga proses deployment atau migrasi database menjadi lebih mudah.
Berikut contoh konfigurasi Envoy yang lain:
@setup
$__container->servers([
'staging' => 'user@ip_address',
'production' => ['user@ip_address -p 8288'],
]);
@endsetup
@setup

$release = date('YmdHis');
$new_release_dir = $releases_dir .'/'. $release;

$branch = "staging";
