Today I would like to share about some Ubuntu 22.04 features of the upcoming Ubuntu stable release. Ubuntu 22.04 Jammy Jellyfish release date is scheduled on April 21, 2022. So, let’s take a look at some new features.

GNOME 42

Ubuntu 22.04 LTS ships with the latest and greatest GNOME 42 desktop environment by default. Most of GNOME 42’s features are enjoyable.

New screenshot tool

One of GNOME 42’s features. Ubuntu 22.04 has a screenshot tool that also includes the screencast (video recording) option. And the screenshot of the selected area, entire screen or current application window can also be taken.

New Ubuntu installer

The installation prompts of Ubuntu 22.04 will look a little different because the installer has been revamped. It was created using Google’s Flutter UI development kit.

Raspberry Pi support

The new Ubuntu 22.04 will support Raspberry Pi models with as little as 2 GB of RAM.

Kernel 5.15

The Kernel 5.15 will come with new features which include a new NTFS file-system driver called NTFS3. This will make Ubuntu 22.04 more compatible with Windows NTFS formatted drives. The new Linux Kernel includes a new in-kernel SMB file service that will provide faster file sharing and more features. And also include support for Amazon’s DAMON (Data Access Monitor) which improves performance and new hardware support for AMD CPUs and GPUs, Apple’s M1 chip, Intel Alder Lake CPUs and so on.

New dock mode

Ubuntu 22.04 has a new addition where the size of the dock can be changed.

Accent Color Selection

With Ubuntu 22.04, a different accent color can be chosen. You can change the default orange theme as you want. The folder icons, notification bars, buttons, and other elements will reflect the selected accent color.

So this is all for now. Hope you enjoy that.

If your friends come to your house, you may need to tell them your WiFi password. For complex passwords, you will need to enter the password.

Having more than a few friends at home can be tedious and annoying. However, you can speed up the entire process by using a QR code that your friends can scan and connect to your network.

Methods as below.

Visit qifi.org from a browser.
Enter the SSID, encryption type and password for your WiFi connection.
Generate a QR code, print it out, and stick it at the wall or something.

Below is a sample screenshot of qifi.org result.

Of course, there might be other tools as well to do the same function. But the above one is relatively quick and easy.

If you don’t want to use websites and you are on smartphones. I think you can also generate QR code of your WiFi by going through the WiFi setting and tap on the one you are connecting.

今回も、Laravelの知っておいた方がいいとおもったことをいくつか紹介します。

Tip – 1　#Laravel #Eloquent Tip :

これはLaravelのv9.8.*で利用可能です。
Eloquentモデル全体を旧関数の第2引数として渡すことができます。
古い関数に提供された最初の引数は、Eloquent属性の名前であると仮定します。

Tip – 2 #squish グローバルヘルパーメソッド

これは、単語間を含む文字列からすべての余分な空白を削除します。steroidsの「trim」みたいなものです。

ということで、今回はこれで終わります。

Today, I would like to share about some tips for optimizing a laravel application. Let’s take a look.

1. Cache routes, config and views

Caching speeds up your application. This is important when deploying a application to a production environment.

To cache your routes, you can use the following command:
php artisan route:cache

To clear the route cache, you can use the following command:
php artisan route:clear

To cache config, you can use the following command:

php artisan config:cache

To cache your views, you can use the following command:

php artisan view:cache

2. Remove unused services

You should remove unused services when the application grows. This can be done by removing the service from the config/app.php file.

3. Remove unused packages

To keep the app clean, you should remove unused packages from the application. This can be done by removing the package from the composer.json file or by running the following command:

composer remove package-name

4. Remove development dependencies

You should also remove development dependencies when deploying to production. This can be done by running the following command:

composer install –prefer-dist –no-dev -o

5. Composer Autoload Optimization

For your applications, you should use the composer autoload optimization feature as the autoloader can take significant time for each request:

composer dumpautoload -o

The -o flag will convert PSR-0/4 autoloading to classmap to become a faster autoloader.

6. Precompile your assets

If npm is used for your front-end development, you should precompile your assets. This can be done by running the following command:

npm run production

This will compile the assets and create public/assets directory.

This is all for now. Hope you enjoy that.
