Grub customization : A lazy weekend journey

Before:

After:

This is what happens when you are bored out of your mind on a weekend and Youtube nudges you to mess around with your GRUB just for the funsies of it.

Next thing you know,you are in the /boot and the /etc folder just trying your best to make your grub look cool and increasing boot default entry timeouts . Here is how I cooked and got cooked in the process. Quick Note: Modifying grub can affect your system's ability to boot,so proceed with caution

For context,I use Linux Mint 22.3-Cinnamon so your package manager command might be different, but the tool itself works the same.

Part 0: Installing grub customizer (For increasing boot default entry timeouts)

Update your packages

Open the terminal and run the update command.It makes sure we have the latest packages before we install grub customizer.

sudo apt update && sudo apt upgrade

Installing grub customizer

Since its not available in default Ubuntu, we will be adding a ppa(personal package archive) for it

sudo add-apt-repository ppa:danielrichter2007/grub-customizer

Once added update your package list again

sudo apt update

Install grub customizer

sudo apt install grub-customizer

To open grub customizer

Just search "grub customizer" in the applications menu and launch it.

You will now be prompted to provide authentication. Enter your sudo password for admin privileges.

After successful authentication

The grub customizer interface shall open like so

Increasing boot default entry timeout

0.Click on the "General Settings" tab

Click on the "+" icon to increase the boot default entry timeout

Click on "Save"

Part 1: Changing grub theme using the terminal

Open up the terminal and run the following command

git clone https://github.com/Lxtharia/minegrub-theme.git

This is gonna clone the repo and save it to our home directory

Lets go into this folder by

cd ./minegrub-theme

Copy the minegrub theme files to the grub theme on your system in the /boot directory using

sudo cp -ruv ./minegrub /boot/grub/themes/

Now we will edit the grub configuration files in the grub directory

sudo vi /etc/default/grub

Im using vim in this case you can use nano or gedit as well for editing files.

Adding the theme with

GRUB_THEME="/boot/grub/themes/minegrub/theme.txt"

Edit in vim press the "I" key to go into insert mode and paste this with CTRL+Shift+V, then quit insert mode using ESC and save it using :wq.

Finally update your grub using

sudo grub-mkconfig -o /boot/grub/grub.cfg

Now,it should detect our custom grub theme

Go reboot and enjoy the view. If things go sideways—or you just wanna show off your setup—hit the comments.

Experience of Learning Flutter Development

Pseudobish — Mon, 12 Dec 2022 07:51:13 +0000

So, to begin with why did I learn Flutter?

It was because of the fact that it came out recently and I had to get my hands dirty in a new technology. I also had interest in mobile apps and how they were made. So lets start with it.

What is Flutter?

So, Flutter is an open source framework by Google.

Mobile UI framework for creating native apps for IOS & Android, which means not only can you learn to develop apps for android devices but also for IOS devices.
As mentioned above that it can develop apps for both Android and IOS devices meaning it only requires single code-base(which is in Dart)which implies we only have to write our app once for multiple devices.

Now, the questions arises.

Why Use Flutter?

Only 1 code base
Very smooth and quick experience when running apps.
If you are looking to develop full stack apps with flutter , it works well with Firebase as a backend.
It uses an Object-Oriented Language known as Dart which is really easy language to pick up.You can refer the docs for dart here.
Uses Material Design out of the box.
It has great docs and guides on its official website.

So, now the question arises what should you know?

A basic to good understanding of programming principles which includes:

Classes
Functions and methods
Variables
Asynchronous code

Flutter Overview:

ITS ALL ABOUT WIDGETS.

So, what are Widgets?

Widgets are the bedrock of flutter applications because without them we cant create anything inside a flutter app.

At first, the root widget that surrounds everything you see on the screen.

Then, nested inside the root widget , we have appbar widget which is at the top.

Inside, the nested appbar widget exists a textbar widget, which has the title of the app.

So, this nesting results in a tree like structure known as the widget tree. The widget tree describes the structure of widgets inside your app.

The resources you can follow are:

Initially the flutter official flutter Docs.
Then Flutter Tutorial for Beginners and you can find the same on Youtube This will be able to clear mostly all the concepts of Flutter and Dart.
After clearing the basics of Flutter and Dart, you can move ahead and try to develop some full-stack apps with flutter and Firebase from here and here

My Initial Flutter Apps:

-Random WordPair Generator

-To Do App

How I develop Flutter Apps:

Download Flutter
Open Visual Studio code.
Install these two extensions

Press Ctrl+Shift+P and choose the option of creating new flutter app, then name your flutter app and you will have a sample app opened in your editor

Then select the location where you want to create the app and name your app.

You will be seeing a sample flutter app, with main.dart file

Open terminal and run the command flutter run choose your emulator and run your app.

Now you will be seeing a running sample app.

With all this you should be good to go with the basics of Flutter Development.
