Medir é uma actividade muito útil. Porque nos deixa tomar melhores decisões, porque nos ajuda a perceber a realidade e porque nos deixa perceber quando algo de extraordinário está a acontecer.

Metrics é uma livraria Java desenvolvida pela Yammer que torna muito simples obtermos métricas sobre as diferentes componentes das nossas aplicações. Foi feita para ser usada em produção, onde é mais necessária, pelo que é eficiente e “leve”.

Vamos ver o que podemos fazer com ela, o que faz sentido medir, e de que forma podemos aceder e tratar os dados produzidos.

CTO da Cult Of Bits, uma startup portuguesa no mundo do software empresarial. Há mais de 10 anos a desenvolver profissionalmente software para a web, sempre baseado na plataforma Java. Um gajo porreiro 🙂

Como aumentar a produtividade e qualidade do produto final no desenvolvimento de aplicações web usando práticas de Continuous Integration.

Alguns tópicos a abordar:

• Ferramentas e melhores práticas;
• O que resulta e o que não resulta. Perigos a prevenir;
• Técnicas simples de:
  • Redução do boilerplate e redução geral do arranque do projecto;
  • Redução do turnaround em ciclos de teste / desenvolvimento;
  • Formação e partilha de informação entre a equipe técnica;
  • Re-utilização e dependency management de artefactos web (Livrarias javascript + CSS e outros);
  • Monitorização da produção de código.

Algumas ferramentas abordadas:

• Jenkins CI Server;
• Eclipse (mas tudo o que apresentarei deverá funcionar co outros IDEs);
• Maven;
• Git;
• etc.

Há um par de décadas a desenvolver software, metade das quais com Java. Cá e lá fora.
Últimos grandes temas: aplicações Web, integração de sistemas, arquitecturas SOA e melhoria de produtividade – frameworks, Continuous Integration, etc.
Desafio actual: desenvolver aplicações web, depressa, bem e sem dor.
É um desafio e pêras…

JBoss Tools is a set of plug-ins that integrate in the Eclipse Integrated Development Environment. Together with the example projects and quick starts from JBoss Central, these reveal themselves invaluable for the Java EE developer. Whether you want to use JPA, CDI or JSF, JBoss Tools provides handy features that will make your life easier. Additional bonus functionality includes Maven integration, runtime detection and deployment in the cloud with support for OpenShift.
In this session we will zoom in on these elements and demo how you would create and deploy a HTML5 application on OpenShift with JBoss Tools.

Koen is currently driving the Eclipse integration of the JBoss Forge project. Before this assignment he was responsible for the Eclipse support and the different workflow editors of the jBPM project. Koen graduated as a Civil Engineer from the Belgian Royal Military Academy and obtained an additional Master’s Degree in Information Technology at the Brussels Free University. Before joining JBoss, he worked respectively in the IT department of the Belgian Army and as a software consultant. Koen is a regular speaker at public events and conferences.

A common complaint you hear a lot about Java development is that it is quite a burden to get started. For a newbie, it takes a lot of knowledge and effort to even put the simplest JSF application to work.
JBoss Forge is an incremental enhancement tool that lets you take an existing Java project and safely work in new functionality. Whether you want to set up JSF, use persistence or enable integration testing with Arquillian, it all becomes a real breeze.
In this session you will learn how to take advantage this powerful new technology. You will see how it can be used to rapidly create, test and deploy enterprise Java applications. Forge truly will turn out to be one of the missing links you have been looking for in Java development.

What is Infinispan, what are its key features and a set of use cases where in which it can be deployed.

Mircea Markus has joined JBoss’s clustering team in 2007 as a core engineer. He has been working on various clustering components, such as JBossCache, PojoCache or JGoups. He is one of the founders of Infinispan project on on which he has been concentrating his efforts for the last two years. He has also the founder of project Radargun – a benchmarking framework data grids.

There exists a range of NoSQL solutions with strong differences in performance, functionality, reliability, isolation, ease of use. This is a technical richness, but a cost in terms of migration, and and when you need to choose one for your next project it becomes a complex research quest.
In this talk we discuss the purpose of Hibernate OGM and how it can help switching from a relational database diving into NoSQL, and switching from NoSQL to NoSQL if you change your mind.
Hibernate OGM (Object Grid Mapper) is built on the robust and proven Hibernate engine and helps you to port existing JPA applications to alternative storage engines decoupling most of application’s code from a specific NoSQL solution.
Sanne will explain how OGM is designed, how to use it, and what to expect next.

Sanne Grinovero is a member of the Hibernate and Infinispan teams at JBoss by Red Hat. He focuses on search and NoSQL capabilities, like Hibernate Search and Infinispan’s integrations with Apache Lucene and Hibernate OGM. He lived in Holland, Italy, Chile, Portugal and currently resides in Newcastle Upon Tyne.
Sanne has been an early adopter of cloud technologies, worked as a consultant focusing on JBoss products and other open source technologies. Spoke at conferences such as Devoxx, JBoss World, JUDCon, Java Day, OpenBlend, Agile Day, various JBug and JUG events. You can follow him on Twitter as @SanneGrinovero.

A Business Process Management System (BPMS) offers you the capabilities to better manage and streamline your business processes. JBoss jBPM continues its vision in this area by offering a lightweight process engine for executing business processes, combined with the necessary services and tooling to support business processes in their entire lifecycles. This allows not only developers but also business users to manage your business processes more efficiently.

A lot has happened in the BPM area over the last few years, with the introduction of the BPMN 2.0 standard, the increasing interest in more dynamic and adaptive processes, integration with business rules and event processing, case management, etc. In this session, we will show you how jBPM5 tackles these challenges, discuss migration to this new plaform and give you an overview of its most important features.

Whether you’re a seasoned Java developer looking to start hacking on EE6 or you just wrote your first line of Ruby yesterday, the cloud is turning out to be the perfect environment for developing applications in just about any modern language or framework. There are plenty of clouds and platform-as-a-services to choose from, but where to start? Join us for an action-packed hour of power where we’ll show you how to deploy an application written in the language of your choice – Java, Ruby, PHP, Perl or Python, with the framework of your choice – EE6, CDI, Seam, Spring, Zend, Cake, Rails, Sinatra, PerlDancer or Django to the OpenShift PaaS in just minutes. And without having to rewrite your app to get it to work the way the cloud provider thinks your app should work.

Check the command-line fu as we leverage Git to onboard apps onto OpenShift Express in seconds, while also making use of the web browser do the heavy-lifting of provisioning clusters, deploying, monitoring and auto-scaling apps in OpenShift Flex.

If you want to learn how the OpenShift PaaS and investing an hour of your time can change everything you thought you knew about developing applications in the cloud, this session is for you!

Num sistema de informação, em alguns contextos, é necessário processar muito informação de forma constante e em simultâneo. Uma das forma de tratamento desta informação é caracterizando-a por tipos e identificando padrões. Isto permite intervir sempre que os padrões acontecem permitindo agir de acordo com esses padrões de forma automática.

Uma abordagem possível é a utilização de uma framework que englobe estes conceitos e que permita tratar a informação de forma autónoma e automática. A framework (N)Esper permite isso mesmo, com garantia de fiabilidade e performance, não descurando a facilidade de utilização e configuração. Depois de identificados os padrões sobre os quais se pretende intervenção, permite vários tipos de estruturas de configuração e de injecção de eventos no motor interno. Em consequência da configuração efectuada, os padrões são identificados e os respectivos subscritores são notificados permitindo assim agir em conformidade, nos mais variados sistemas, quando esse padrão ocorre. A framework apresentada concretiza estes paradigmas de forma intuitiva e de fácil implementação. Uma abordagem tradicional com uma base de dados relacional não seria tão eficaz como demonstrado pela plataforma.

Serão abordados temas como:

• Aplicações práticas das actuais soluções NoSQL;
• Aplicação de Vector Clocks no versionamento de dados em soluções de integração (muito mais fiável do que a utilização de Timestamps);
• Utilização de algoritmos como as Merkel Trees na sincronização de dados;
• Sistemas de cache de dados (inc. de informação de sessão) distribuída;
• Utilização do Apache Zookeeper para configuração distribuída e monitorização.
