Python with GenAi and DevSecOps Training 2025 – Session 8

VGLUG is dedicated to empowering rural college students through technology education.
As part of this initiative, we conduct weekly training sessions on Python With GenAI and DevSecOps..

Due to the large number of participants, the training is organized into six teams:

• Python & GenAI –  Linus Torvalds(Team 1) &  Grace Hopper(Team 2): Assigned to Engineering students
• Python & GenAI –  Richard Stallman(Team 1) & Aron Swatz (Team 2): Assigned to Arts and Science students
• DevSecOps –  Ada Lovelace (Arts) & Bob Thomas (Engg): Comprising both Engineering and Arts students

These sessions focus on practical knowledge of Python, GenAI, DevSecOps, free and open-source tools, and also include social awareness and community engagement activities.

Python With GenAI – Richard Stallman and Aron Swatz(Arts) :

Session 1: Problem Solving Using String – Kowsalya & Dilip

This weekend’s VGLUG student meetup centered around a key programming skill: Problem Solving Using Strings. The session was designed to strengthen logical thinking and improve Python coding skills through practical, hands-on activities.

Participants were divided into Multiple teams, each given a unique string-based logic problem. These problems were carefully curated to apply concepts of looping — including for, while, and nested loops — to solve real-time challenges involving strings.

Each team worked collaboratively, and by the end of the session, all teams successfully implemented and explained their logic. Two students stood out by confidently presenting their solutions in front of everyone. They not only walked through their approach but also engaged in a Q&A session, making the learning experience truly interactive and peer-driven.

The session reflected the power of learning through problem-solving, discussion, and teamwork.

Session 2: Git – Mathusoothanan & Dilip

In this weekend’s VGLUG session, students were introduced to the basics of Git and GitHub.
Everyone created their own GitHub accounts and learned how to initialize and manage repositories.
They practiced key commands like git init, add, commit, and push.
Each student tried pushing their own code to a personal repository.
It was a hands-on session that built confidence in version control and collaboration.

What is Git?

🔹 Git is a version control system.
🔹 It helps developers track changes in their code and collaborate with others.
🔹 Git was created by Linus Torvalds (creator of Linux) in 2005.

Why Use Git?

Problem Without Git	Solution With Git
Accidentally deleting code	Git lets you go back to old version
Team members overwrite changes	Git lets everyone work together safely
Confusion over file versions	Git tracks every change and update

Basic Git Commands:

Command	Meaning
git init	Start a new Git project
git status	Check the current state
git add filename	Stage file changes
git commit -m "message"	Save the changes with a message
git log	View previous commits
git clone URL	Copy a remote project to local
git push	Upload your changes
git pull	Download latest changes from others

Git Workflow (Simple Steps)

git init → Start a project

git add → Stage the changes

git commit → Save the changes

git push → Send to GitHub or GitLab

Session 1: Operators – Vijayalakshmi & Deepak

What are Operators in Python?

Operators are symbols or keywords used to perform operations on variables and values.
Example: +, -, *, /, ==,

1. Arithmetic Operators

Operator	Description	Example
+	Addition	5 + 2 = 7
-	Subtraction	5 - 2 = 3
*	Multiplication	5 * 2 = 10
/	Division	5 / 2 = 2.5
//	Floor Division	5 // 2 = 2
%	Modulus (remainder)	5 % 2 = 1
**	Exponentiation	2 ** 3 = 8

2. Assignment Operators

Operator	Meaning	Example
=	Assign	x = 5
+=	Add and assign	x += 2 → x = x + 2
-=	Subtract and assign	x -= 2
*=	Multiply and assign	x *= 2
/=	Divide and assign	x /= 2

3. Comparison (Relational) Operators

Operator	Description	Example
==	Equal to	5 == 5 → True
!=	Not equal to	5 != 3 → True
>	Greater than	5 > 3 → True
<	Less than	5 < 3 → False
>=	Greater or equal	5 >= 5 → True
<=	Less or equal	5 <= 4 → False

4. Logical Operators

Operator	Description	Example
and	True if both are True	True and True → True
or	True if one is True	True or False → True
not	Inverts condition	not True → False

5. Bitwise Operators (used for binary numbers)

Operator	Description
&	AND
`	`
^	XOR
~	NOT
<<	Left shift
>>	Right shift

6. Identity Operators

Operator	Example
is	x is y
is not	x is not y

Session 2: Wikisource – Vasanth

What is Wikisource?

• Wikisource is a project that collects and shares free, editable, and reliable texts in many languages.
• It includes books, poems, speeches, historical documents, religious texts, and more.
• All content is in the public domain or under a free license, so anyone can use, share, and even edit the texts.
• It supports multiple languages, including Tamil (ta.wikisource.org) for Tamil literary works.

What Kind of Content Is Found on Wikisource?

• Classic literature (Tamil, English, and many other languages)
• Speeches by freedom fighters, politicians, thinkers
• Constitutional and legal documents
• Letters, autobiographies, translations, etc.

Why Is Wikisource Important?

• Preserves knowledge: Keeps old and rare texts alive digitally.
• Promotes free access: Everyone can read, copy, and reuse texts.
• Supports education: Students and researchers can access reliable texts easily.
• Encourages community participation: Anyone can help proofread and upload texts.

File Permissions & Ownership

ls -l
chmod +x script.sh
chmod 755 file.txt
sudo chown user:group file.txt

tar -xvf archive.tar
gzip file.txt
gunzip file.txt.gz

Disk Usage & Space

df -h
du -sh folder/

Networking Commands

ip a
ping google.com
netstat -tuln

Package Management (Debian/Ubuntu)

sudo apt update
sudo apt upgrade
sudo apt install package-name
sudo apt remove package-name

File Searching

find / -name “*.pdf”
find . -mtime -1
grep “search_text” *.txt

User Management

sudo adduser username
sudo deluser username
su – username

Combine Commands

mkdir test && cd test
command1 || echo “Failed”
cd folder; ls; pwd

Bonus

history
alias ll=’ls -la’
crontab -e
man grep

Session 2:  F-Droid – Mathusoothanan

• In this weekend’s VGLUG session, students were introduced to F-Droid, the free and open-source app store.
• They explored how it works differently from the Play Store — focusing only on FOSS (Free and Open Source Software) apps.
  Each student installed the F-Droid app and browsed privacy-respecting alternatives.
• They discussed how F-Droid supports user freedom and data safety.
  It was an eye-opening session on digital rights and ethical tech choices.

• F-Droid is a community-driven app store focused only on Free and Open Source Software (FOSS).
• Unlike Google Play Store, F-Droid doesn’t track users or collect personal data.
• All apps available on F-Droid are free to download, use, and modify — with source code openly available.

Students explored FOSS alternatives for commonly used apps like:

• Simple Gallery (instead of Google Photos)
• NewPipe (instead of YouTube)
• K-9 Mail (instead of Gmail)
• Aegis Authenticator (instead of Google Authenticator)
• The session also covered how F-Droid builds transparency and trust by verifying apps using reproducible builds.
• Students learned how to safely install the F-Droid APK and enable unknown sources on Android.
• Discussion included how F-Droid can help people avoid ads, trackers, and proprietary restrictions.

• A demo on basic terminal commands like ls, cd, pwd, and mkdir sparked curiosity.
• Students explored the Ubuntu interface and understood the concept of file systems.
• It was an eye-opening session that kickstarted their journey into the world of Free and Open Source Software.

Session 2: Discussion about opensource- Vignesh

students had an open discussion about the importance of Free and Open Source Software (FOSS).
They explored how open source gives freedom to use, modify, and share software without restrictions.
Real-life examples like Linux, Firefox, VLC, and Wikipedia were shared.
The session helped students understand the community-driven nature of open source development.
It was a thoughtful and inspiring day that built awareness of tech freedom and collaboration.

INFORMATION:

We’re excited to share that the National Law School of India University (NLSIU) has conducted a case study on the impact of Free and Open Source Software (FOSS) and FOSS communities in India. We are honored that the VGLUG Foundation has been featured for our meaningful contributions to FOSS awareness, development, and community building.
