AGENDA

1. Why Linux over other OS?
Purpose: Discussion
Questioner: Mr.Madhavan

Reviews:
1). Simple & Minimal
2). No need much Hardware ie. use minimal hardware compared other any OS.
3). No bloatware & virus.
4). Anybody can access Source code.
5). Open and free to install and use.

2. Flaws of Linux?
Purpose: Discussion
Questioner: Mr.Rajesh

Reviews:
1). Lack of available Drivers. ex: earlier NVIDIA doesn’t provide drivers for their GPUs. so we need to use third party drivers for accessing their GPUs.
2). So many distros(distributors or flavours) are available. beginners struggle to choose which is perfect for their need.

3. Can we add extra disk space for Linux after installation(dual boot Linux and windows)?
Purpose: Discussion
Questioner: Mr.Madhvan

Reviews:
1). we can use unallocated space on disk.this is easy procedure to follow.
2). Incase we don’t have unallocated space, must reinstall the OS.

4. By the way User:
Purpose: Share Information
Questioner: Mr.Rajesh

Reviews:
1). Its actually just a kind of Joke.The installation of Arch Linux is not like most other distros. You have to do the whole installation from the command line. There is no Graphical user interface(GUI).
2). So you’ve to install it from scratch like using command line and text editor.
3). So Arch users think themselves superior from other distro users. And tell everyone that they use Arch.
4). And they say “By the way I use Arch”.

5. Practice:
Purpose: Learning
Command: “make” & “cmake”

Description:
make – The purpose of the make utility is to determine automatically which pieces of a large program need to be recompiled, and issue the commands to recompile them. you can use make with any programming language whose compiler can be run with a shell command.
cmake – CMake is an open-source, cross-platform tool that uses compiler and platform independent configuration files to generate native build tool files specific to your compiler and platform.

6. Why most of the servers uses Linux?
Purpose: Share Information
Questioner: Ms.Jeslin

Reviews:
1). Linux based servers uses less amount of resources. ie. uses less RAM and Disk. So users have many space for work. so that 90% of servers from worldwide uses Linux based servers.
2). Stability, Security & Flexibility.
3). More reliable -rare malware and cyber threat.
4). Its Open source unlike windows closed source.

7. Can anybody access the source code on Linux?
Purpose: Discussion
Questioner: Mr.Vignesh

Reviews:
1). Yes. Everybody has the access to customise and edit the source code for their own use.
2). By using Kernel you can access.
3). But the authority people have access to reach repositories for main code.
4). They are the people to edit and develop the origin source code.
5). Incase if you find any Bug, you can rise the query and ask them to Fix the bug. they test the code again and release globally.
6). On other hand, you can also develop and maintain the source code on your own repository.

8. Why most of the PC makers release PCs on windows over Linux?
Purpose: Share Information
Questioner: Mr.Vignesh

Reviews:
1). First of all, Linux doesn’t have single distro for all users like windows does.
2). Windows release versions like 7,8,10 & 11 are easily understandable for consumers.
3). So they are all chooses easy choice.
4). Every user is not a developer and CS background peoples. So they want easy GUI. they hate commands for every action.
5). Earlier Linux distros are uses commands for most of the action. Nowadays it developed and Linux also has much better GUI compared to windows.
6). So PC makers starts migrating to Linux over windows. Dell already does.

9. Can anybody create applications for Linux? it is profitable?
Purpose: Share Information
Questioner: Mr.Vignesh

Reviews:
1). Yes. you can. also the new developer release the software on open source it will help to develop the software. and it will also inspire the other developers.
2). You can’t make money from directly. But you can make money through shopping and productivity app to advertise your product and make profit from it.
3). Thats why most of the game developers like EA, epicgames, Nintendo, Rockstargames, etc., don’t release their Linux versions. Reason behind this only money.

To know more about:

Repository:

A repository contains all of your project’s files and each file’s revision history. You can discuss and manage your project’s work within the repository.
You can own repositories individually, or you can share ownership of repositories with other people in an organization.
You can restrict who has access to a repository by choosing the repository’s visibility.
For user-owned repositories, you can give other people collaborator access so that they can collaborate on your project. If a repository is owned by an organization, you can give organization members access permissions to collaborate on your repository.

Linux Distros:

A Linux distribution — often shortened to “Linux distro”
developers keep creating and distributing new Linux-based OSes is that they simply can. The Linux kernel is free. The apps are free. The resources to create a whole operating system on top of the kernel are free.
Ubuntu. Easy to use. Unique user experience.
Linux Mint. Familiar user interface with Windows.
Linux Lite. Windows-like user interface.
Manjaro Linux. Not an Ubuntu-based distribution.

Linux OS:

Ubuntu. One of the most popular and best Linux distributions is Ubuntu. A variation of Debian, Ubuntu is a product of UK-based Canonical and offers Linux solutions for desktops, servers, IoT devices, and more.
Today, there are over 600 active Linux distros.
Currently, more than 300 Linux distributions are actively maintained. There are commercially backed distributions, such as Fedora (Red Hat), openSUSE (SUSE) and Ubuntu (Canonical Ltd.), and entirely community-driven distributions, such as Debian, Slackware, Gentoo and Arch Linux.

Source code:

Source code (also referred to as source or code) is the version of software as it is originally written (i.e., typed into a computer) by a human in plain text (i.e., human readable alphanumeric characters).
Source code can be written in any of the hundreds of programming languages that have been developed. Some of the most popular of these are C, C++, Cobol, Fortran, Java, Perl, PHP, Python and Tcl/Tk.
A program’s source code is not necessarily all written in the same programming language. For example, it is common for programs that are written primarily in C to contain portions that are in an assembly language for optimization of processor efficiency. This is the case with the Linux kernel (i.e., the core of the Linux operating system).
