Java 8 Stream API. A different way to process collections.David Gómez García
A look on one of the features of Java 8 hidden behind the lambdas. A different way to iterate Collections. You'll never see the Collecions the same way.
These are the slides I used on my talk at the "Tech Thursday" by Oracle in June in Madrid.
Java is Object Oriented Programming. Java 8 is the latest version of the Java which is used by many companies for the development in many areas. Mobile, Web, Standalone applications.
Collections Framework is a unified architecture for managing collections, Main Parts of Collections Framework
1. Interfaces :- Core interfaces defining common functionality exhibited by collections
2. Implementations :- Concrete classes of the core interfaces providing data structures
3. Operations :- Methods that perform various operations on collections
Constructor is a special member method which will be called automatically when you create an object of any class.
The main purpose of using constructor is to initialize an object.

This is a beginner's guide to Java 8 Lambdas, accompnied with executable code examples which you can find at https://github.com/manvendrasinghkadam/java8streams. Java 8 Streams are based on Lambdas, so this presentation assumes you know Lambdas quite well. If don't then please let me know I'll create another presentation regarding it with code examples. Lambdas are relatively easy to use and with the power of stream api you can do functional programming in Java right from start. This is very cool to be a Java programmer now.
Abstract: kaChing powers the largest social investment site on the web with nearly 500,000 registered users. Our mission is to make the investment world open by offering transparent investment vehicles that directly compete with mutual funds.
Over the past year and a half, we have built a large feature set and evolved our software continuously with very short iterations and (almost) no regression. In this talk, I will present our experience building a large test-driven code base from the ground up. Using concrete examples, we will have a look at component based APIs, declarative programming, minimizing the concepts of an API, specific cases of separation of concern and interactions with third-party software. We will look at multiple programming paradigms from languages such as Scala, shell script and Prolog and see how these ideas can be embedded as syntactic sugar in your Java.

Functional Thinking for Java Developers (presented in Javafest Bengaluru)KonfHubTechConferenc
Moving to functional programming can result in significantly better code and productivity gains. However, it requires a paradigm shift: you need to move away from imperative and object-oriented thinking to start thinking functionally.
Functional Programming in Java 8 - Exploiting LambdasGanesh Samarthyam
The programming world is moving towards functional programming. All the major and popular programming languages (including Java, C++, C#, Swift, and Python) support functional programming. Functional programming languages such as Clojure, Scala, and F# are on the rise. This talk introduces functional programming to those who are new to this paradigm using lambda functions in Java 8. The talk will cover syntax and semantics of lambda functions, moving from external iteration to internal iteration, and how lambda functions can result in shorter and more readable code. If you are new to functional programming and want productivity gains from using Java’s lambda functions, this talk is certainly for you.
Evolving with Java - How to Remain EffectiveNaresha K
Slides from my Java2Days 2020 talk - "Evolving with Java - How to Remain Effective".
Developers find themselves in need to continually update themselves with the rapidly changing technologies to remain relevant and deliver value. However, by keeping a few things in mind and with certain practices, this can be a pleasant experience. In this presentation, I share my experiences learning and evolving with Java in the last 15+ years. The ideas presented are generic enough to be applicable for people using any technology stack. However, the code examples are in Java/ JVM languages.
We start by understanding the importance of gradual improvement. To keep motivated for continuous improvement, in my experience, responsiveness is a vital element. I share my experience of how to increase your responsiveness. To be able to change/ experiment continuously in our code, we need to ensure that we don't break anything. We explore the necessary techniques to achieve safety. Often we mistakenly consider lack of familiarity as complexity. We explore options to come out of this confusion. We then touch upon the impact of learning paradigms and multiple languages available on the JVM. Finally, we touch upon another important aspect of continuous improvement that is unlearning. We conclude the session by summarising the principles.
Do you want to learn functional programming in Java using lambda expressions introduced in Java 8? Do you want to explore the foundational concepts to explore powerful stream API? This presentation provides an overview of lambda functions introduced in Java 8 through examples. Topics covered: What is functional programming, creating lambda expressions, functional interfaces, built-in functional interfaces, and method references.
Make sure you have JDK 8 installed for trying out the programs as you go through the self-contained programming examples.
Let us explore Java 8 features and start using it in your day to day work. You will be surprised how Java has evolved to become so different yet easy & powerful. In this presentation, we discuss Java 8 Stream API.
Learn how to use lists in Java, how to use List<T> and ArrayList<T>, how to process lists of elements.

Functional Thinking - Programming with Lambdas in Java 8Ganesh Samarthyam
Functional programming is on the rise. Almost all major and mainstream languages support functional programming features, including C++, Java, Swift, and Python, and Visual Basic. With Java 8’s lambda functions, Java now supports functional programming. Moving to functional programming can result in significantly better code and productivity gains. However, it requires a paradigm shift: you need to move away from imperative and object-oriented thinking to start thinking functionally. That’s what this workshop will help you achieve: it will help you make your shift towards functional programming. The workshop will introduce lambda functions in Java with examples from Java library itself. Presented in OSI Days 2015 workshop - http://osidays.com/osidays/shifting-to-functional-programming-lambdas-for-java-developers/
We aren't sure about you, but working with Java 8 made one of the speakers lose all of his hair and the other lose his sleep (or was it the jetlag?). If you still haven't reached the level of Brian Goetz in mastering lambdas and strings, this talk is for you. And if you think you have, we have some bad news for you, you should attend as well.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

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.
