The document discusses the history and features of the Linux operating system. It notes that Linux was developed in 1991 by Linus Torvalds, a student at the University of Helsinki. Torvalds released the Linux source code publicly, allowing thousands of developers to contribute to its growth. Linux is an open-source operating system that provides many of the same functions as proprietary systems like Windows and macOS, including user interfaces, task management, and support for various hardware devices.
Linux is the best-known and most-used open source operating system. As an operating system, Linux is software that sits underneath all of the other software on a computer, receiving requests from those programs and relaying these requests to the computer's hardware.
What is Linux?
Command-line Interface, Shell & BASH
Popular commands
File Permissions and Owners
Installing programs
Piping and Scripting
Variables
Common applications in bioinformatics

In the presentation I have tried to cover the Evolution of Linux as an Operating System. The most of the content used is freely available on Internet , I have just tried to streamline it and summarize it as cleanly as possible from my point of view. Any improvements, suggestions, comments are most welcom.
This ppt gives information about:
1. Administering the server
2. Correcting installation problems
3. Setting up user accounts
4. Connecting to the network
5. Configuring utilities
I have described all about linux OS starting from basics.
I guess this PPT will really be very very helpful for you guys.
This was one of the most appreciable PPT in my time when i presented it in my class.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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).

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
