Global Day of Coderetreat (17/11)

Hi JUGgers!

Ready for our next event? We hope so!

This time we invite you to participate next Saturday 17th in the Global Day of Coderetreat. Coderetreat is a day-long, intensive practice event, focusing on the fundamentals of software development and design. By providing developers the opportunity to take part in focused practice, away from the pressures of 'getting things done', the coderetreat format has proven itself to be a highly effective means of skill improvement. Practicing the basic principles of modular and object-oriented design, developers can improve their ability to write code that minimizes the cost of change over time.

The process is really simple:

  1. Start with a simple programming problem: Conway's Game of Life
  2. We will work with different partners to discuss and solve the problem
  3. We will add restrictions to force us to consider different approaches
  4. After each round, we will throw out your code and repeat!
More info:

This event will be possible thanks to Codurance,  they will host event and all the drinks and food we will have during all the day (including coffees and other beverages), so thank you so much for your support!

Orquestación en Kubernetes para desarrolladores Java (29/9)


Ya estamos de nuevo a la carga con un nuevo evento (próximo 29/9) organizado en colaboración con la comunidad Hispana! 

Desde España, e integrada con la primera conferencia Java en Galicia, el XantarJ, el grupo de usuarios de Vigo en colaboración con el CoruñaJUG y el grupo local XantarDev serán los encargados de orientar (nuestra 4a sesión del año) en el mes de Septiembre de 2018: Orquestación en Kubernetes para desarrolladores Java

Java 10 viene con muchas características necesarias para ejecutar aplicaciones JVM en Docker. El objetivo de este taller es desplegar una aplicación Java usando Docker & Kubernetes con los ajustes y límites de memoria y CPU adecuados.

En esta sesión, construiremos una imagen de Docker con una aplicación Java basada en el framework Netty. Esta aplicación tendrá un tamaño muy pequeño siguiendo las mejores prácticas de Docker y se aprovechará de Java Platform Module System (JPMS) presentado en la versión JDK 9. Desplegaremos la aplicación en Kubernetes y la escalaremos para demostrar cuán poderosa es hoy en día la JVM en conjunto con Docker y Kubernetes.

Luego expondremos las métricas de aplicaciones y JVM, que serán consumidas por Prometheus, un sistema que registra datos de series temporales (telemetría) para monitorear y alertar, y usaremos Grafana para consultar y generar métricas desde los pods de la aplicación.

Durante todo el workshop, descubriremos los errores más comunes al trabajar con Docker y la JVM y cómo evitarlos.

Únete a este evento, reserva tu plaza y haz parte de las comunidades de habla hispana!


Si es posible trae tu laptop o equipo portátil para practicar con nosotros, tendremos 2 horas de sesiones técnicas y ejercicios prácticos.

Simon Ritter on tour! JDK 9, 10, 11 & Beyond: Delivering New Feature in the JDK (2/5)

Hi devs!

We are really happy to announce a new talk, this time by a very well known (and great) speaker: Simon Ritter. Simon will be running a tour around Spain (with more people from Azul Systems ) during the first 2 weeks of May and Azul have contacted us in case we are interested in hosting a talk by them ... and we are, of course! ;-)

We will be the first city in their tour and this is the "crazy tour" they have planned to: 2/5 Barcelona, 3/5 Castellón, 4/5 Valencia, 7/5 Malaga, 8/5 Sevilla, 9/5 Madrid, 10/5 Vigo, 11/5 Coruña

About the talk, Simon has shared with us his proposal to talk about the new features and evolutions on the JDK. Here you can see the details:

JDK 10 was released only six-months after JDK 9, demonstrating that the new fast cadence for the OpenJDK works. Even with such a short development cycle, there were still over a hundred new features covering the language, core libraries and the JVM.

In this session we’ll take a look at how the Java platform is evolving with the introduction of big features like the Java Platform Module System (JPMS) in JDK 9, local variable type inference in JDK 10 and dynamic class file constants in JDK 11. We’ll also cover many of the smaller features that will make your life as a developer easier.

What might JDK 12, 13 and 14 include? To answer that question, we’ll explore some of the longer-term plans for Java, like project Amber, Loom and Valhalla.

Many of you may know Simon Ritter, but in case not, he is the Deputy CTO of Azul Systems. He has been in the IT business since 1984 and holds a Bachelor of Science degree in Physics from Brunel University in the U.K. 

Simon joined Sun Microsystems in 1996 and started working with Java technology from JDK 1.0; he has spent time working in both Java development and consultancy. Having moved to Oracle as part of the Sun acquisition, he managed the Java Evangelism team for the core Java platform, Java for client applications and embedded Java. Now at Azul, he continues to help people understand Java as well as Azul’s JVM technologies and products. Simon has twice been awarded Java Rockstar status at JavaOne and is a Java Champion. He currently represents Azul on the JCP Executive Committee and on the Java SE Expert Group (JSR 379, 383 and 384). You can follow him on Twitter with @speakjava

Nothing more, remember to RSVPed and see you there!

Arquitectura y despliegue de aplicaciones con Openshift (19/4)

Hola JUGgers!

Volvemos a la carga con otro evento (ojo en poco tiempo tendremos varios) ;-) ¡Estad atentos!

En esta ocasión nos centraremos de la mano de GFT en la solución de RedHat para el desarrollo, despliegue y gestión de contenedores en la nube: Openshift

Openshift es una de las plataformas PaaS líderes en gestión de contenedores Docker que ofrece RedHat y la idea del evento, además de conocer por encima la arquitectura de la plataforma, es explicar la necesidad de una herramienta como esta en nuestro día a día, dónde los contenedores Docker, DevOps, Sistemas de integración continua, etc… están a la orden del día. Entraremos también un poco más en detalle para explicar cómo se suelen desplegar las aplicaciones, la mayoría de ellas microservicios, y lo más importante, basada en nuestras propias experiencias en proyectos actuales dentro de GFT.

Los ponentes en esta ocasión serán Ivan Fontanals y Jordi Sola de GFT. Ivan es un entusiasta de las nuevas tecnologías, arquitecturas y sistemas de información. Lleva más de 10 años trabajando como arquitecto de software, sobretodo en temas de J2EE, y durante los últimos 2-3 años, metido también en temas de DevOps en GFT. Jordi es un entusiasta del desarrollo, especialmente en Java. Se ha especializado en el control de calidad del código y estándares de desarrollo. Tras 8 años en GFT, ha descubierto su interés por el mundo de los contenedores y el ‘continuous release’, y ha enfocado su trabajo en la automatización de procesos en OpenShift. En su tiempo libre, participa de varios proyectos OpenSource, manteniendo librerías propias, colaborando en el desarrollo del lenguaje de programación Ceylon (https://ceylon-lang.org) y como miembro asociado de la comunidad JCP.

Agradecer una vez más a nuestros amigos de Ubiqum que nos ceden el espacio de sus oficinas para realizar la charla y también dar las gracias a GFT que nos proporcionarán algo de comer y de beber para hacernos más llevadero el networking de después de la charla ;-)

Nada más, recuerda reservar tu plaza a través de Meetup y nos vemos el próximo Jueves 19 en Ubiqum!

Gambling with Leopards - Ben Evans (24/1)

Hi JUGgers !!!

Ready for our next event... next Wednesday 24th? (yes, we know without too much time in advance) but... we would like to the advantage of Ben Evan's being in our city and we've convinced him to give us a talk ;-)

This is a fairly light talk, where Ben talks about the experience of writing a full-size reference application - BetLeopard - which is an open-source implementation of an engine for betting on horse racing.

In the talk Ben will show several different ways of approaching a calculation problem - first by using Java 8 lambdas, then by using Hazelcast in-memory data grid and then with Apache Spark for processing and then again with the new Hazelcast Jet technology.

It covers processing techniques, some domain design, serialization as well as showing how to get started with Spark and Jet. It should be useful for anyone who wants to learn about different approaches in modern distributed processing.

This time we have to thank Ocado for offering us his facilities for the event and inviting us to something to eat and drink and do some networking ;-)

Have a good weekend and see you next Wednesday!


This year to prevent the no-show effect for those people that register and never come and to avoid problems to our sponsors ( buying food for not present people ) and to us ( searching for bigger rooms ), we'll charge 2 EUR to everyone registering and we will give back that amount for those that really attend the event.

Don't forget to register

Lazy Java - Mario Fusco (18/01)

Hi devs !!!

We continue this year 2018 with a great speaker Mario Fusco and a very interesting topic : lazyness ( a purpose for this new year ? ;) )

Like all imperative languages Java is, with some minor but notable exceptions, an eagerly evaluated programming language. Nevertheless the introduction of lambdas in Java 8 also allowed the adoption of some lazy patterns and data structures that are more typically employed in functional languages. Streams represent the most evident example of how also native Java API has taken advantage of laziness, but there is a number of other interesting scenarios where laziness can be an effective solution to quite common problems. In fact laziness is the only possible technique to process potentially infinite amount of data, or more in general to delay the expensive evaluation of an expression only when and if it is necessary. But laziness is even more than that: for instance the reader monad delays not only a computation but also the need of external dependencies thus lowering the abuse of dependency injection, while a trampoline uses laziness to delay and then linearize recursive calls preventing the overflow of the stack. The purpose of this talk is illustrating why and how implementing laziness in Java with practical examples delivered with both slides and live coding sessions.

Mario is a senior software engineer at Red Hat working at the development of the core of Drools, the JBoss rule engine. He has a huge experience as Java developer having been involved in (and often leading) many enterprise level projects in several industries ranging from media companies to the financial sector. Among his interests there are also functional programming and Domain Specific Languages. By leveraging these 2 passions he created the open source library lambdaj with the purposes of providing an internal Java DSL for manipulating collections and allowing a bit of functional programming in Java. He is also a Java Champion and the co-author of "Java 8 in Action" published by Manning.

Hope you can make it and we can finally meet there.


This year to prevent the no-show effect for those people that register and never come and to avoid problems to our sponsors ( buying food for not present people ) and to us ( searching for bigger rooms ), we'll charge 2 EUR to everyone registering and we will give back that amount for those that really attend the event.

Don't forget to register

Happy coding

Let's try for 2018...

Hi JUGgers!

First of all, happy new Year! We hope this 2018 will be really good for all of you in every way ;-)

We want to share with you all few words about of our hopes and expectations for this year. As a developers we have a lot of ideas to grow, like be able to attract more women, organize events for younger people (to introduce them to the world of software development), run a hackaton (may be with another developer community?), organise events more focused in another technologies (may be learn new languages, why not?), contribute to opensource projects or try to help other people in need. To achieve all this, we need to grow, and from the organising team we are always open to welcome members who want to be active and go in this direction. So if you have time, we invite you to participate more actively in the community to propose or organise events or any other activity that you can do to contribute to all of us. Ping us in any case ;-)  

Looking back on 2017, we work hard to organize more than 1 event per month (at least 14 events) and a really big one ( our lovely Java & JVM Barcelona Conference ). As you can imagine organizing events is always an unpaid effort under no circumstances, which requires us a significant amount of personal time (which we would like to have more of). Reviewing last year, we realised that the attendance rate was really low in many, if not most, cases (below 30%) and on reflection, we think this is not a good sign. Everyone has ups and downs (and we all have our own schedules), and we can always understand that there is a percentage of people who for various reasons cannot attend to our events. Last minute contingencies may also arise, but when not even half of the people registered for an event attend, it denotes a lack of seriousness, if not indifference, and we think it is not good. There are many people involved around an event, and also companies and people that are working for those companies, who spend time organizing a space, welcoming the attendees, setting up a room, buying some food and drink, etc. We think it is not fair for all of these people (organisers included) that their efforts are not rewarded, since at the end the number of people who attend is not by far the expected. It also happens that there are people who can remain on the waiting list and therefore are unable to attend to events for those who do not decide to cancel their attendance.

For these reasons we have decided to introduce some small changes in the way in which we are organising our events. This year in order to prevent the no-show effect for those people that register and never come that are creating problems to our sponsors and to us, we'll charge a small amount of money (about 2-3€) to everyone registering to one of our events. Finally, you do not have to worry about the money if you finally attend to one of our events, because we will give back that amount for those that really attend. We don't need or want the money, but we hope that in this way, the people who register will really come to the events we organize with a lot of care.

We hope you understand the reasons that push us to making this movement, but we cannot accept to continue disrespecting the organizers of the events as well as the companies that dedicate their time and effort to us.

Happy coding and see you soon! ;-)
