Java
This slide is a shot overview to Java from start up to now. Where we were? Where we are? Where we’re going? Know how. Was hold in Lindholmen October, 2013 http://www.lindholmen.se/en/node/35950
Once upon a time in the C++ century, the Great King of Sun said people need Duke, The PDA (a medieval version of a tablet). He picked his bravest knights – Naughton, Sheriden and Gosling – and entrusted them a secret mission to travel the universe in search for a perfect language that Duke can use.
After three years of a dangerous journey in a world of bits, bytes and memory leakages, on an Asian isle they found it. Java made of Oak has been discovered.
When they returned the King was not in power anymore. New world was ruled by a mysterious organisation, World Wide Web. Our brave knights honoured it with the glorious Java. And the world became perfect…
Mani and Rafal will take your through an exciting story of great programmers, multi-billion company wars, and - most importantly – language features. The history of Java, from its inception till just about today.

this slide contains about basic introduction of java.it will be helpful for a java beginner. it also useful for java lecture course in your versity.programming with java is very essential for every student.this silde may help you to progress your skill & lernt abc about java.
why Java is so popular is the platform independence. Programs can run on several different types of computer; as long as the computer has a Java Runtime Environment (JRE) installed, a Java program can run on it.
Java is a strongly typed programming language because every variable must be declared with a data type. A variable cannot start off life without knowing the range of values it can hold, and once it is declared, the data type of the variable cannot change

JavaFX 8 everywhere; write once run anywhere by Mohamed TamanJavaDayUA
With tens of millions of clients continuously downloading binaries from our repositories, we decided to offer an OSS client that natively supports these downloads. In this talk, we will share the main challenges in developing a highly-concurrent, resumable, async download library on top of Apache HTTP client. We will cover other libraries we tested and why we decided to reinvent the wheel. We will see important pitfalls we came across when working with HTTP and how using the right combination of techniques can improve performance by an order of magnitude. We will also see why your initial assumptions may completely change when faced with other players on the network. Consider yourself forewarned: lots of HTTP internals, NIO and concurrency ahead!

What is Java
Java is a programming language and a platform. Java is a high level, robust, object-oriented and secure programming language. It was originally developed by Sun Microsystems which was initiated by James Gosling and released in 1995 as core component of Sun Microsystems' Java platform (Java 1.0 [J2SE]).
The latest release of the Java Standard Edition is Java SE 10. With the advancement of Java and its widespread popularity, multiple configurations were built to suit various types of platforms. For example: J2EE for Enterprise Applications, J2ME for Mobile Applications.
The new J2 versions were renamed as Java SE, Java EE, and Java ME respectively. Java is guaranteed to be Write Once, Run Anywhere.
Java String
In Java, String is basically an object that represents sequence of char values. An array of characters works same as Java string. In Java programming language, strings are treated as objects. The Java platform provides the String class to create and manipulate strings.
Exception in Java
An exception is an unwanted or unexpected event, which occurs during the execution of a program i.e at run time, that disrupts the normal flow of the program’s instructions.
Exception is an abnormal condition.In Java, an exception is an event that disrupts the normal flow of the program. It is an object which is thrown at runtime.
What is Exception Handling
Exception Handling is a mechanism to handle runtime errors such as ClassNotFoundException, IOException, SQLException, RemoteException, etc.
Collections in Java
The Collection in Java is a framework that provides an architecture to store and manipulate the group of objects.
Java Collections can achieve all the operations that you perform on a data such as searching, sorting, insertion, manipulation, and deletion.
Java Collection means a single unit of objects. Java Collection framework provides many interfaces (Set, List, Queue, Deque) and classes (ArrayList, Vector, LinkedList, PriorityQueue, HashSet, LinkedHashSet, TreeSet).
The Java Collections Framework is a collection of interfaces and classes which helps in storing and processing the data efficiently. This framework has several useful classes which have tons of useful functions which makes a programmer task super easy.
Basic of Selenium
Selenium is one of the most widely used open source Web UI (User Interface) automation testing suite.
Selenium tutorial provides basic and advanced concepts of Selenium. Our Selenium tutorial is designed for beginners and professionals.

What is Spring
Spring is a lightweight framework and an open source Java platform that provides comprehensive infrastructure support for developing robust Java applications very easily and very rapidly. Spring framework was initially written by Rod Johnson and was first released under the Apache 2.0 license in June 2003. This tutorial has been written based on Spring Framework version 4.1.6 released in Mar 2015. It can be thought of as a framework of frameworks because it provides support to various frameworks such as Struts, Hibernate, Tapestry, EJB, JSF, etc. The framework, in broader sense, can be defined as a structure where we find solution of the various technical problems.
The Spring framework comprises several modules such as IOC, AOP, DAO, Context, ORM, WEB MVC etc. We will learn these modules in next page. Let's understand the IOC and Dependency Injection first.
Web Service
A web service is any piece of software that makes itself available over the internet and uses a standardized XML messaging system. XML is used to encode all communications to a web service. For example, a client invokes a web service by sending an XML message, then waits for a corresponding XML response. As all communication is in XML, web services are not tied to any one operating system or programming language java can talk with Perl; Windows applications can talk with Unix applications.
Web Services tutorial is designed for beginners and professionals providing basic and advanced concepts of web services such as protocols, SOAP, RESTful, java web service implementation, JAX-WS and JAX-RS tutorials and examples.
Web service is a technology to communicate one programming language with another. For example, java programming language can interact with PHP and .Net by using web services. In other words, web service provides a way to achieve interoperability.
Web services are self-contained, modular, and distributed.

Features of Java
Object Oriented − In Java, everything is an Object. Java can be easily extended since it is based on the Object model.
Platform Independent − Unlike many other programming languages including C and C++, when Java is compiled, it is not compiled into platform specific machine, rather into platform independent byte code. This byte code is distributed over the web and interpreted by the Virtual Machine (JVM) on whichever platform it is being run on.
Simple − Java is designed to be easy to learn. If you understand the basic concept of OOP Java, it would be easy to master.
Secure − With Java's secure feature it enables to develop virus-free, tamper-free systems. Authentication techniques are based on public-key encryption.
Architecture-neutral − Java compiler generates an architecture-neutral object file format, which makes the compiled code executable on many processors, with the presence of Java runtime system.
Portable − Being architecture-neutral and having no implementation dependent aspects of the specification makes Java portable. Compiler in Java is written in ANSI C with a clean portability boundary, which is a POSIX subset.
Robust − Java makes an effort to eliminate error prone situations by emphasizing mainly on compile time error checking and runtime checking.
Multithreaded − With Java's multithreaded feature it is possible to write programs that can perform many tasks simultaneously. This design feature allows the developers to construct interactive applications that can run smoothly.
Interpreted − Java byte code is translated on the fly to native machine instructions and is not stored anywhere. The development process is more rapid and analytical since the linking is an incremental and light-weight process.
High Performance − With the use of Just-In-Time compilers, Java enables high performance.
Distributed − Java is designed for the distributed environment of the internet.
Dynamic − Java is considered to be more dynamic than C or C++ since it is designed to adapt to an evolving environment. Java programs can carry extensive amount of run-time information that can be used to verify and resolve accesses to objects on run-time.
Basic concepts of OOPs are:
Object
Class
Inheritance
Polymorphism
Abstraction
Encapsulati

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.

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.
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.

3. Where we were?
In June 1991:
James Gosling starts working
on an interpreter (called "Oak"),
which, several years later is
renamed "Java."

Compiler
Executable
File
4. Where we were?
In August 1991:
- A small group of Sun engineers called the
"Green Team“, led by James Gosling,
demonstrates basic user interface ideas and
graphics system to Suns co-founders
- They believed that the
next wave in computing
was the union of digital
consumer devices and
computers
5. Where we were?
From 1991 to 1995:
Events & evolution such as:
- Mosaic 1.0, the first graphical browser for
the Internet, is released
- Interactive Cable TV
- Java compiler in Java has been
implemented (James had previously
implemented it in C)
- Java compatible browsers (Netscape)
6. Where we were?
From 1991 to 1995:
This concept was too much advanced for the
industry at the time BUT it was just right for
the Internet, which was just starting to take
off. In 1995, the team announced that the
Netscape Navigator Internet browser would
integrate with Java technology.
7. Where we were?
So:
- The first programming language was created,
a cross-platform computing environment NOT
tied to any particular operating system or
microprocessor!
- Applications written in Java will run anywhere
- Eliminating incompatibility between operating
systems and versions of operating systems.
8. Where we were?

Also Many embedded devices are based on Java:
set-top boxes, printers, web cams, games, car
navigation systems, lottery terminals, medical
devices, parking payment stations, etc
15. Where we are?
- Java is not a new programming language any more.
- From early 1995 until now we have seen how it has
developed from a JDK (Java Development Kit) to
Java EE (Enterprise Edition) and new Java Open
Source frameworks and technologies.
- At the beginning, Java was about a few packages
and APIs you could use to solve small problems. But,
what about now, when Java has branched out into
several technologies and Open Source frameworks?
16. Where we are?
There are four Java Platforms:
1) Java Standard Edition (Java SE)
2) Java Enterprise Edition (Java EE)
3) Java Micro Edition (Java ME)
4) JavaFX

29. Where we’re going? Open Source
New languages build on JVM
Why Scala over Java:
- Increased productivity due to reduced
verbosity
- Developers can mix and match
imperative and functional programming
paradigms as needed
- Built-in functionality for parallelism and
concurrency
34. Know how!
- Usability: focusing on end users
- Focusing on problems: not technologies, tools
and platforms, select the easiest ones
- Be realistic: obtainable competence
- Make a list of what is important for your
Software lifecycle. Identify/prioritize them &
then select
- You can change your mind: most of your
technology choices can change
35. Know how!
- Easy & Quick: select a SW that you know to
be easier and quicker to prototype.
- Standard vs. Open Source: check the open
source products licenses.
Open Source != Free Software
- Start with capabilities, not implementations
- Cost: consider the total cost
- Involve your team early
- Testing and deployment: software that makes
testing difficult should be avoided
36. Know how!
- Avoid Lock-in: e.g. if SW has limitation, runs
on a certain Operative System or environment
- New versus existing software: reuse
