Mentalni jaz sve dublji
HrvatskaSvijet
Ali za pojedinca sve
uži za preskočiti!

Egalitarni sindrom i rentni mentalitet
Sramota je ne samo ne uspjeti.
Nego i probati!
Zavist je moneta socijalizma.

The document provides an overview of the Graal VM, which is a new just-in-time (JIT) compiler for the Java Virtual Machine (JVM) that brings high performance to scripting languages via the Truffle API. It discusses how Graal generates machine code from an optimized AST rather than bytecode, and how the Truffle API allows creation of language interpreters in Graal. Performance benchmarks show Graal improving performance for languages like JavaScript, Ruby, and R compared to other implementations. Future directions include supporting more languages and compiler optimizations in Graal's extensible framework.

Javantura v4 - Let me tell you a story why Scrum is not for you - Roko Roić

HUJAK - Hrvatska udruga Java korisnika / Croatian Java User Association

This document discusses why Scrum may not be suitable for certain situations and provides 10 anti-patterns of Scrum usage. It suggests that Scrum works best for complex product development when used as intended for the right jobs. However, it may not be a good fit if a team is too small, projects are too simple, skill sets are too varied, or if the principles of Scrum are not accepted or fully learned. The document recommends considering alternative frameworks like Kanban that may impose less rigidity if Scrum proves restrictive.

Javantura v4 - Test-driven documentation with Spring REST Docs - Danijel Mitar

HUJAK - Hrvatska udruga Java korisnika / Croatian Java User Association

Spring REST Docs is a framework that allows generating documentation for REST APIs through automated tests. It produces documentation that is accurate, readable, and avoids code pollution by generating snippets from tests. The documentation can be output in formats like HTML, Markdown, and PDF. Tests are written using MockMVC or RestAssured to make requests, and snippets of the request/response are extracted to include in documentation. This allows documentation to be updated automatically whenever tests change.

Javantura v7 - Behaviour Driven Development with Cucumber - Ivan Lozić

HUJAK - Hrvatska udruga Java korisnika / Croatian Java User Association

Javantura v7 - Behaviour Driven Development with Cucumber - Ivan Lozić Behaviour-Driven Development (or TDD for that matter) is one of the pillars of Software Quality. While it is very important, not many of us do it or do not have the support from the management to invest time in it. Commonly, it has been described as a waste of time or an intangible effort conflicting with the deadlines. In this presentation, I would like to share my experiences with the Behaviour-Driven Development, the effects of not having it at all, as well as the outcomes of working on projects where a significant amount of behavior is automated with Cucumber tool. By attending this session you will be able to learn what BDD and Cucumber are, how to build Cucumber tests and hear about first-hand experiences around automating specifications.

HUJAK - Hrvatska udruga Java korisnika / Croatian Java User Association

Javantura v7 - Learning to Scale Yourself: The Journey from Coder to Leader - Daniel Strmečki Your success depends on others, a 1-man army can only achieve so much. The only way to progress from coder to leader is to learn how to scale yourself. Nowadays, you can become a Senior Developer with just a few years of experience. After that, there are many roads and possibilities you can take. Whether you decide for a developer, architect, manager or a mixed career, at one point, you will need to become a leader. In the first chapter of the lecture we will start a discussion on how to get there. Since your time is limited, you need to mentor, coach, motivate and engage others. Start with making a stable foundation, like setting up a proper onboarding process. If you help people around you, they will for sure talk about it, and your manager will hear it. Also, demonstrate ability in everyday work: coding, project management, client-focus, communication and care about others. Always stick to your values and keep high standards. In the second chapter we will discuss the challenges that turn up once you get there. At that point you will deal with people more than technology. You will need to step away from coding for meetings very often. Interruptions will happen every day and it we be very hard to maintain “the flow”. You will need to learn how to delegate and drive topics without implementing them yourself. Visit the lecture to find out some techniques for dealing with interruptions, meetings, prioritization, people and their motivation.

The State of Java and Software Development in Croatia (Community Keynote) by dr. sc. Branko Mihaljević, Aleksander Radovan, and doc. dr. sc.Martin Žagar at the 8th International Java Conference in Croatia - JavaCro '19 In this community keynote by HUJAK, we want to present and compare the current state of Java and related software development in Croatia, our part of Europe, and worldwide. Therefore, we will start by discussing the latest global trends in software development and what does it mean in our rapidly evolving world full of new technologies based on IoT, Machine Learning and AI, Blockchain, Virtual Reality, and Robotics, to which we must respond to ASAP. Of course, when addressing those contemporary technology trends, we will focus mostly on our country and the region. In the other part, we will discuss the major events in the world of Java that happened in the last few years since Java 8 and Java 9/10/11 were widely adopted. We will see what Java 11 and 12 brought us and what developers are mostly using (or not) and why, as well as what will be there interesting in Java 13 and beyond, including new features from incubator projects Amber and Valhalla, and new ideas from projects Loom, Panama, Skara, and Metropolis. Once again, we are going to take a typical developer’s point of view on software development challenges in this part of Europe, and we will discuss the future of our software developers from the perspective of how to become one (educational institutions and practice) and how to get/earn a good job (local employers and the job market). We intend to close this keynote with details of (y)our favorite Java community aka HUJAK.

HUJAK - Hrvatska udruga Java korisnika / Croatian Java User Association

HATEOAS is without a doubt, the least understood pillar of REST. It seems difficult to implement and shows no immediate reward for it, so many developers don't even bother. The truth is, it just has some bad PR and a horrible acronym that sounds like a breakfast cereal. Join me to take a look at the theory and practice behind using hypermedia by examining both web services and web clients. Along the way we will look at some exciting upcoming Spring HATEOAS features, like the Affordances API, and talk about what the future holds for hypermedia in your web services.

HUJAK - Hrvatska udruga Java korisnika / Croatian Java User Association

Individual microservices are relatively easy to develop, but managing a distributed system composed of microservices is never a simple task. Kubernetes helps, but it falls short of providing everything such a system needs. This is where the Istio Service Mesh comes in. Running microservices in production, you'll soon realize you want things like traffic splitting, automatic connection retries, timeouts and failovers, secure communication and authentication between your services, distributed metrics, tracing and logging. By introducing Istio into your architecture, you get all of that and more. And you get most of it without changing your code at all. In this talk, you'll see a demonstration of Istio in action and learn about the tricks that make its magic possible.

Bugs are a daily cause of stress in our work as Java developers. Those pesky things can hide behind core concepts in Java 9 and 10—there is no way out of this. If we don’t keep up to date with new Java versions, bugs will take over our projects. But can we have fun hunting them? You bet! How about solving a series of Java puzzles as a way to master concepts and save a lot of time finding those tricky bugs? In this session, attendees can help the bug hunters solve fun Java challenges, gain a clear understanding of what causes the most-stressful bugs—and have fun eliminating them from projects.

Javantura v6 - Building IoT Middleware with Microservices - Mario Kusek

HUJAK - Hrvatska udruga Java korisnika / Croatian Java User Association

In H2020 EU project symbIoTe (symbiosis of smart objects across IoT environments) we have been building IoT middleware based on microservices programmed in Java with Spring Boot and Spring Cloud components. Here I will present our experiences in developing such services in distributed team across EU and employed by 15 organizations. I will present organizational and technical advantages and drawbacks as well as our choices in building such system.
