Shell: A Command-Line Interpretor that connects a user to Operating System and allows to execute the commands or by creating text script.
Process: Any task that a user run in the system is called a process. A process is little more complex than just a task.
File: It resides on hard disk (hdd) and contains data owned by a user.
X-windows aka windows: A mode of Linux where screen (monitor) can be split in small “parts” called windows, that allow a user to do several things at the same time and/or switch from one task to another easily and view graphics in a nice way.
Text terminal: A monitor that has only the capability of displaying text stuff, no graphics or a very basic graphics display.
Session: Time between logging on and logging out of the system.
Getting started with setting up embedded platform requires audience to understand some of the key aspects of Linux. This presentation deals with basics of Linux as an OS, Linux commands, vi editor, Shell features like redirection, pipes and shell scripting
Here, you can learn all information about Shell Script.
1. What is Shell Script?
2. Types of Shell Script.
3. Use of Shell Script.
4. Command line of Shell Script.
5. Example of Shell Script.
Makefile actually is an old concept from UNIX development. Makefile is based upon compiling rules for a project and improve the project development efficiency. In a big project, there are many files in different folders. Of course you can write a DOS batch file to build whole project. But makefile can judge which steps should be done first, which steps can be ignored, and even more complicated goals. All of these are decided by the rules in makefile, instead of manually specified.

make is a basic tool to define pipelines of shell commands.
It is useful if you have many shell scripts and commands, and you want to organize them.
Even if it has been written to automatize the build of compiled language programs, make is also useful in bioinformatics and other fields.
How Symfony changed my life (#SfPot, Paris, 19th November 2015)Matthias Noback
Before Symfony was spelled with a capital “S” there was another symfony, the first version of the framework. It already meant a lot to me at the time. But with the arrival of Symfony 2 it became clear that something very important was happening in the world of PHP programming. It appears that this framework is able to turn amateur website makers (like I used to be) into actual software developers. What is the secret? What makes Symfony so special? And why am I still hooked?
We’ll look at pieces of code, the Symfony ecosystem, the people behind it, the things that have been written about it, and the experience that I have with it. We’ll take a trip down memory lane, collecting pieces for our Symfony scrapbook, while we try to construct an answer to these questions.

Makefiles are great for a lot of things and are generally used to build executable programs and libraries from source code but they are not limited to only that. This talk will probably convince you to start adding makefiles in your Python or any other programming project.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

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).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

What are makefiles?
make - automagically build and manage your programs.
compile quickly with a single command
recompile is even quicker
Subhashini V Tutorial on make
7. Introduction Compiling Makefiles Example Extras Motivation
How does it work?
Give targets (usually a file to be created)
Specify dependencies for each target.
Give command to create target from dependencies.
‘make’ recursively builds the targets from the set of
dependencies.
recompilation - time-stamp of modification
Subhashini V Tutorial on make
8. Introduction Compiling Makefiles Example Extras Object file
.h and .cpp
.h files contain
declarations.
functions that the class promises.
.cpp files contain
definitions
implementations of the promised methods.
other functions that are not a part of any class.

BigInt assignment example
The BigInt data type in RSA
BigInt.h - with proposed methods : +, -, *, /, !
BigInt.cpp - with implementation of methods
rsa.cpp - ONLY needs #include “BigInt.h”.
Don’t need BigInt.cpp.

14. Introduction Compiling Makefiles Example Extras Macros Naming Phony-Targets
Naming the file
Naming and running the make file.
makefile - run with make
Makefile - run with make
give any filename - run as make -f < filename >
make picks the first target in the file and executes the commands
if the dependencies are more recent than the target.
Subhashini V Tutorial on make
15. Introduction Compiling Makefiles Example Extras Macros Naming Phony-Targets
Phony targets
Dummy targets to run commands. They don’t actually create files.
make all
make clean
