This document provides an introduction to the Java programming language. It outlines the objectives of learning Java as understanding basic programming concepts, object-oriented principles, Java APIs, and exception handling. It then defines Java as both a programming language and platform, describes Java's syntax and how it is compiled and interpreted, and explains the Java virtual machine and application programming interface that make up the Java platform. It also gives examples of primitive data types, operators, control flow structures, and how to use arrays and strings in Java.

As the author of an open-source serialization library in Scala, I've undergone a lot of struggle to understand and harness the power of Scala's type system. My library was based on parsing pickled Scala signatures, which was a subterranean and sparely documented feature of Scala 2.8. I wanted to serialize and deserialize options, lists and maps, which required defeating type erasure when serializing while skating by on type erasure when deserializing. I struggled with multiple constructors, checking for annotation types, specialization, more. The new reflection libraries introduced in Scala 2.10 provided easier access to the same information I had been getting from the pickled signatures. This talk will address practical aspects of type mining, providing a library of hands-on examples using the Scala 2.10 reflection API.

TypeScript is an amazing substitute for JavaScript that solves a bunch of significant problems that are surprisingly common in large JavaScript code bases. But, by solving those problems, it also creates a new one: it's now easier than ever to create larger and more complex code bases. It turns out that accommodating that complexity while supporting all the different JavaScript environments is quite a challenge.
Which is why TypeScript has multiple module systems, unfortunately with confusing names and poor guidance. In this session, we sort out the mess and talk about the differences between internal and external modules, writing client and server code, how the TypeScript modules map to JavaScript modules in different versions of JavaScript, and about integration with build tools like Gulp.

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!

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.

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:

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.

Editor's Notes
Java is an object oriented programming language similar to C++. It is a high level programming language. Platform mean Java runs on a virtual machine. Normally, programs are compiled and built for a specific architecture and operating system. Since Java needs to run on different OS a virtual platform is used on the top of default operating system.
JVM and Java API together is called Java Runtime Environment (JRE)
Java Runtime Environment (JRE)
Name of the public class if the file contains more than one class, becomes the name of the file with “.java” extension
Primitive data types: Because java program has to run on different architecture and OS, the size of the data should remain same. Otherwise, on different machines the output will be different. Refere
Interfaces acts like alias for objects. Interface are taught later.
Unicode is an unique number that is given to every character which works on any platform, any language and any hardware. It facilitates the display of any national characers on any of the browsers. All the popular current browsers supports this unicode system
