Linux is a free and open-source operating system created by Linus Torvalds in 1991. It began as an alternative to proprietary operating systems and can now run on a variety of devices from watches to supercomputers. Linux distributions package the Linux kernel with other free software to create complete operating systems. Popular distributions include Debian, Red Hat, and Slackware. The Linux community continues to enhance and support the operating system through collaboration.

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.
differences between unix and linux:
Some people think Unix and Linux as synonyms, but that's not true. Many operating systems were developed to be like Unix but none of them got the popularity as Linux. Linux is the clone of Unix. It has several features similar to Unix, still have some key differences let us see in the presentation..

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images
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).

3. WHAT IS LINUX
• Linux is PC-UNIX in which the kernel was created for PC/AT compatibles
by Linus Torvalds of Finland. The name is derived from the kernel's creator.
• Linux is, in simplest terms, is an OPERATING SYSTEM.
• It is the software on a computer that enables applications and the computer
operator to access the devices on the computer to perform desired functions.
• Linux is very similar to other operating systems, such as Windows and OS X.
4. BIRTH OF LINUX
• On August 25, 1991, a Finn computer science student named Linus Torvalds made the following
announcement to the Usenet group comp.os.minux:
“I'm doing a (free) operating system for 386(486) AT clones. This has been brewing since april, and is starting to get
ready. I'd like any feedback on things people like/dislike in minix, as my OS resembles it somewhat “
• The “Minix” Torvalds referred to is a variant of the UNIX operating system, used as a guideline for
his free operating system he wanted to run on the x86-based consumer PCs of the day.
• “gnu” refers to the set of GNU tools first put together by Richard Stallman in 1983. UNIX, the
operating system that started it all, had its origins in the old Bell Labs back in the early 60s.
5. • Torvalds built the core of the Linux operating system, known as the kernel.
• A kernel alone does not make an operating system, but Stallman's GNU tools were from a
project to create an operating system as well a project that was missing a kernel to make
Stallman's operating system complete.
• Torvalds' matching of GNU tools with the Linux kernel marked the beginning of the Linux
operating system as it is known today.
• Today, Linux is a multi-billion dollar industry, with companies and governments around the
world taking advantage of the operating system's security and flexibility.
6. • One of the most noted properties of Linux is where it can be used. Windows and
OS X are predominantly found on personal computing devices such as desktop
and laptop computers.
• Other operating systems, such as Symbian, are found on small devices such as
phones and PDAs, while mainframes and supercomputers found in major
academic and corporate labs use specialized operating systems such as AS/400 and
the Cray OS.
• Linux, which began its existence as a server OS and has become useful as a
desktop OS, can also be used on all of these devices. “From wristwatches to
supercomputers,” is the popular description of Linux' capabilities.
WHERE LINUX IS?
8. LICENSING
• Code is contributed to the Linux kernel under a number of licenses, but all
code must be compatible with version 2 of the GNU General Public License
(GPLv2), which is the license covering the kernel distribution as a whole.
• Copyright assignments are not required for code contributed to the kernel.
All code merged into the mainline kernel retains its original ownership; as a
result, the kernel now has thousands of owners.
10. DEVELOPER COMMUNITY
• One of the most compelling features of Linux is that it is accessible to
developers; anybody with the skills can improve Linux and influence the
direction of its development.
• Developer communities can volunteer to maintain and support whole
distributions, such as the Debian or Gentoo Projects.
11. USER COMMUNITY
• User can make valuable contributions to the development of Linux.
• With online communities such as Linux.com, LinuxQuestions, and the many
and varied communities hosted by distributions and applications, the Linux
user base is an often vocal, usually positive advocate and guide for the Linux
operating system.
12. DISTRIBUTION
Although Linux is originally the kernel created by Linus, it does not function as an OS generally available with
only the kernel.
The combination of the kernel and some application software supporting it for use as a OS is called a
"distribution".
TYPES OF DISTRIBUTION:
1. REDHAT SERIES
2. SLACKWARE SERIES
3. DEBIAN SERIES
13. Redhat series:
The main distributions are the following:
Turbo Linux
LASER5 Linux
Kondara MNU/Linux
Vine Linux
Slackware series:
The main distributions are the following:
Slackware
Plamo Linux
Debian series :
The main distribution is the following:
Debian GNU/Linux
14. WHY ONE SHOULD GO FOR LINUX ??
• Free for download: no licensing issues or costs
• Freedom to share with your neighbour
