This document provides an overview of common Linux software and how to install additional software. It discusses the major desktop environments GNOME and KDE and default applications like Firefox, Thunderbird, and OpenOffice. It describes the file structure with directories like home, bin, etc. It also outlines several methods for installing software, including via package managers, downloading binaries or source code. The key difference between Linux and Windows is that Linux has a different file structure and installation process which can cause culture shock for new users.

LInux: Basics & File System:The Unix operating system was conceived and implemented in 1969 at AT&T's Bell Laboratories in the United States by Ken Thompson, Dennis Ritchie, Douglas McIlroy, and Joe Ossanna. First released in 1971, Unix was written entirely in assembly language, as was common practice at the time. Later, in a key pioneering approach in 1973, it was rewritten in the C programming language by Dennis Ritchie (with exceptions to the kernel and I/O). The availability of a high-level language implementation of Unix made its porting to different computer platforms easier.
It is a simple powerpoint presentation on Linux Operating System of its brief and simplified introduction of this Operating System.
This is based on Ubuntu version of Linux.
A beginners guide to get familiar with the Linux and learn the most commonly and frequently used commands. Most of the commands are expected to run across all well known Linux distributions. Plus, there are a few commands for the advanced users as well.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

4. Default Fedora Desktop
The default desktop has three distinct areas. From
top to bottom, the areas are:
The menu panel
The desktop area
The window list panel
5. The Desktop AreaThe Desktop Area
●
Computer - This contains all volumes (or disks) mounted on
the computer. These are also listed in the Places menu.
Computer is equivalent to My Computer on Microsoft Windows.
●
Home - This is where the logged-in user stores all files by
default, such as music, movies, and documents. There is a
different home directory for each user, and by default users
cannot access each others' home directories. Home is
equivalent to My Documents on Microsoft Windows.
●
Trash - Deleted files are moved to Trash. Empty Trash by
right-clicking the icon and clicking Empty Trash.

20. The most important subdirectoriesThe most important subdirectories
inside the root directory are:inside the root directory are:
●
/bin : Important Linux commands available to the average user.
●
/boot : The files necessary for the system to boot. Not all Linux
distributions use this one. Fedora does.
●
/dev : All device drivers. Device drivers are the files that your Linux
system uses to talk to your hardware. For example, there's a file in
the /dev directory for your particular make and model of monitor,
and all of your Linux computer's communications with the monitor
go through that file.
●
/etc : System configuration files.
●
/home : Every user except root gets her own folder in here, named
for her login account. So, the user who logs in with linda has the
directory /home/linda, where all of her personal files are kept.
●
/lib : System libraries. Libraries are just bunches of programming
code that the programs on your system use to get things done.
21. The most important subdirectoriesThe most important subdirectories
inside the root directory are:inside the root directory are:
●
/mnt : Mount points. When you temporarily load the contents of a
CD-ROM or USB drive, you typically use a special name under /mnt.
For example, many distributions (including Fedora) come, by default,
with the directory /mnt/cdrom, which is where your CD-ROM drive's
contents are made accessible.
●
/root : The root user's home directory.
●
/sbin : Essential commands that are only for the system administrator.
●
/tmp : Temporary files and storage space. Don't put anything in here
that you want to keep. Most Linux distributions (including Fedora) are
set up to delete any file that's been in this directory longer than three
days.
●
/usr : Programs and data that can be shared across many systems
and don't need to be changed.
●
/var : Data that changes constantly (log files that contain information
about what's happening on your system, data on its way to the printer,
and so on).
23. Commands:
/ (root directory)
/root – home directory of the user root
pwd – you can see your home directory
df – to see disk space available
cd – to change to different directory or to go back to home dir
.. - move to parent directory
ls – list the contents of a directory; Options: -l (more info)
-a (displays hidden files)
-t (sort by time)
-r (oldest first)
Example: ls –ltr : display an long list of files that are sorted by time, display the oldest ones first
Some of the basic commands you should
learn are the ones that help you navigate
the file system.
24. cp : copy one file to another
rm : remove a file
man : ask for the manual (or help) of a command
e.g. man cd ask for the manual of the command cd
cat : to show the content of a text file
e.g. cat abc.txt show the content of abc.txt
whoami : to show the username of the current user
Directory is denoted by a / (slash) character
Executable program by a *
Hidden file preceded by a . (dot)
25. Names in blue are directories, indicated by a
letter d at the beginning of the line
The concept of simple file and
directory is similar to DOS
26. Text editorsText editors

2. Eclipse.
27. One way to install: Package Install tool
Go to "System->Administration->Synaptic Package Manager"
1. Put the keyword in the "Quick Search" Box
2. Click "Search"
3. Browse and look for the software package
4. Right click it and Select "Mark for Installation"
5. Click the button "Apply"
It looks for the packages on the Ubuntu Repository server and
download, install, configure the software automatically for you.
i.e. Try to install wireshark
28. Another way to install: Binary Install
Look for the software on the Internet
Download the prebuilt binary
Follow the installation instructions
if it is .deb package, double click and install it
if it is a self-extrating package, make it executable and run it
Try to install chrome browser
29. One more way: Command Line
There is a command for install the package: "apt-get"
• Open a terminal window
Click "Applications->Accessories->Terminal"
• Search a package and get the package name
Type on the terminal "apt-cache search xxxxx | more"
Notes: press "Space bar" to display next page
• Install a package from Internet
Type the command "sudo apt-get install xxxx"
Notes: You may be asked to your login password
You also may be asked "Y/N" for confirmation
i.e. Try to install gdb, Java, etc.
30. The last way to install
Download the source code
Compile and install it, using the command "make install"
That's how you programmed and executed it.
