Distributed matters Barcelona (20-21/11)

Hi JUGgers!

As many of you may know, every year we were supporting noSQL matters as a Community partners. This year won't be different, and because of that we are happy to announce that we are again one of the Community partners of the noSQL conference (now renamed to Distributed matters)!

In their 4th annual event of NoSQL matters @Barcelona, they are introducing a new twist to our beloved NoSQL & Big Data crowd. They are now adding several new topics to the theme and rebranding to distributed matters. The conference covers topics like: Distributed systems, Microservices, DCOS, Cloud Management, Database solutions, DevOp operations and, of course, NoSQL and Big Data.

Distributed matters @Barcelona will take place on 20th – 21st November 2015. You can check the agenda:

• Training day (20.11.15) with several half-day sessions -> http://bit.ly/trainingsBCN
• Conference day (21.11.15) with 2 tracks in parallel -> http://bit.ly/dmconfBCN

Famous names like: Scott Feinberg (The New York Times), Bart Samwel (Google, Inc.), Susan Potter (Lookout), Tugdual Grall (MapR) and many more will be presenting during the conference day.

The tickets sale is on and the amount is limited! And because we are a Community partner, we have a special code to get 20% off to the members of our MeetUp.

Hope to see you there and remember, distributed matters! ;-)

Experience Design for APIs (28/10)

Hi devs!

Sabemos que las APIs, que se están convirtiendo en el verdadero estándar de facto de comunicación en Internet, ¿no? Justamente por este motivo nos hemos animado a organizar un evento enfocado en el Diseño de APIs para el próximo día 28/10 (en castellano e inglés).

Como desarrolladores estamos definiendo interfaces API para desplegar aplicaciones móviles, Servicios Cloud, IoT y estrategias Big Data. Las opciones son múltiples, y debemos seguir las mejores prácticas de diseño para asegurar el éxito de nuestra empresa o startup.

En colaboración con nuestros compañeros de la comunidad API-Connection hemos organizado este evento a fin de dar a conocer las mejores prácticas en Diseño de APIs.

La agenda será la siguiente: 

- Diseño de Soluciones de Seguridad con APIs (25") por Eduard Palomeras

Eduard es Consultor de APIs, Identity y Access Management en CA Technologies. Su foco es describir soluciones de software de seguridad para la mejora y securización de las infraestructuras TI de las empresas.

- Experience Design for APIs (30") - Ronnie Mitra

Como Director de la API Academy en Europa, su misión es ayudar a los diseñadores de APIs a construir interfaces de manera efectiva. Es un presentador frecuente en temas de APIs y contribuye con Blogs, artículos y videos a varios sitios y publicaciones. Esta presentación será en inglés. 

Después para finalizar, tendremos el clásico turno de preguntas y respuestas. 

Nada más pues, no os olvidéis de reservar a través de Meetup, sobretodo añadiendo vuestro DNI en la reserva para entrar en el edificio. 

Os esperamos !

Q&A with the Hibernate team (13/10)

Hi JUGgers!

October is being a busy month... don't you think so? In order to not change this rhythm, we have the pleasure to announce our next event centered on Hibernate (someone knows anything about it?) for the next 13th and this time we will be waiting for you at the Mobile World Centre at 7pm.

This time we will have the visit of the Hibernate Team from Redhat and we were thinking about what kind of event we could organize, and what better than a Q&A session with the Hibernate Team?

We will all discuss:

- Hibernate ORM (including the latest 5.0 release)
- Hibernate Search (full-text search for your application)
- Hibernate Validator and Bean Validation
- Hibernate OGM (Object Mapper for NoSQL stores)

Come with your questions and be warned that the Hibernate team will ask *you* questions on how you use the Hibernate projects, what you like and what new features you want.

Remember, the Hibernate team will be all in Barcelona next Tuesday 13th so mark this day in your agenda, RSVP'ed via Meetup and come to exchange conversations with all of them.

See you next Tuesday!

Drools engine, jBPM...and friends (6/10)

Hi JUGgers !!!! eyy, no time to sleep !!!! here we have another event... for the next week!

We know we have other plans next week, but we could not say no to the Drools & jBPM team (cause they will come to Barcelona next week), in order to invite them to give us a talk about what they are doing and how ;-)

Because of that, we have the pleasure to invite you next 6th of October focused on Drools and the jBPM ecosystem that will be hosted in La Fontana at 7pm.

In this session the main Drools and jBPM team will give an overview of the Drools rule engine, the OptaPlanner scheduling engine, the jBPM workflow engine and the Workbench web application that ties it all together for business users.

Drools is a Business Rules Management System (BRMS) solution. It provides a core Business Rules Engine (BRE).

OptaPlanner is a constraint satisfaction solver. It optimizes business resource planning. Use cases include Vehicle Routing, Employee Rostering, Job Scheduling, Bin Packing, Cloud Optimization and more.

jBPM is a flexible Business Process Management (BPM) Suite. It makes the bridge between business analysts and developers. Traditional BPM engines have a focus that is limited to non-technical people only. jBPM has a dual focus: it offers process management features in a way that both business users and developers like it.

KIE Workbench is the webapp that ties it all together. It’s based on Uberfire, Errai and Dashbuilder.

We would like to have you all onboard on this event, but unfortunately we have a limited space, and because of that we need to ask to RSVP'ed in our event in Meetup.

Hope to see you next 6th!

Aeron: The next generation in high-performance messaging (8/10)

Hi guys !!!! We are back again !!!

This time we present an interesting event next 8th of October focused on messaging and high-performance in collaboration with other communities: FIBAlumni, ScalaBcn and Clojure Bcn.

Does TCP not meet your required latency consistently? Is UDP not reliable enough? Do you need to multicast? 

What about flow control, congestion control, and a means to avoid head of line blocking that can be integrated with the application? Or perhaps you're just fascinated by how to design for the cutting edge of performance? Maybe you have tried higher level messaging products and found they are way too complicated because of the feature bloat driven by product marketing cycles. 

Aeron takes it back-to-basics with a pure focus on performance and reliability. We have built it from the ground up with mechanical sympathy in its DNA. The data structures are lock-free, copy-free, and even persistent for our functional friends. Interaction with the media is layered so you can swap between UDP, Inifiniband, or Shared Memory as required. 

Aeron is open-source with implementations in Java and C++ that interoperate. There are no unnecessary features to bloat the implementation, yet the design is open so that it can be composed into higher level abstractions. This talk will focus on the design of Aeron and what we learned trying to achieve very consistent performance. We will explore the challenges of dealing with reliable message delivery over UDP and the data structures necessary to support transmission and retransmission in in a lock-free manner.  

Martin has over 2 decades of experience building complex and high-performance computing systems. He is most recently known for his work on Aeron and SBE. Previously at LMAX he was the co-founder and CTO when he created the Disruptor. Prior to LMAX Martin worked for Betfair, three different content companies wrestling with the world largest product catalogues, and was a lead on some of the most significant C++ and Java systems of the 1990s in the automotive and finance domains. He blogs at mechanical-sympathy.blogspot.com, and can be found giving training courses on performance and concurrency when he is not cutting code to make systems better.

Don't miss this great opportunity and come !!! Btw, be careful, this time we are not using MeetUp, please register in the eventBrite event page as the seats are limited.

See you next 8th of October!

Java EE 8 - An instant snapshot (21/5)

Hello JUGgers!

Are you ready for the next event? And ready for a great Java & JVM langs conference this summer in Barcelona? We hope so, we are working hard on that! ;-)

Regarding the next event, we would like to invite you to our next talk focused on the status of Java EE 8 by David Delabassee, the next 21th of May at 7pm at FIB

Java EE 7 has been finalised mid 2013 and from J2EE to Java EE 7, much has changed ... but we are not done yet! Through the years, Java EE has always reinventing itself. Java EE 8 will be no exception to this rule! 

In this session, we will look at the current state of Java EE 8. We will review the various new JSRs that will be part of Java EE 8 (e.g. MVC, JSON-B, Security JSR). We will obviously also look how the existing technologies will evolves in Java EE 8 (e.g. Servlet 4 which brings HTTP/2 support, JMS's plan to replace Message Driven Beans, CDI/EJB alignment, JAX-RS 2.1, etc.).

We will finally conclude this discussion by looking at how you can get involved in those works.

David Delabassee is a Software Evangelist working for Oracle; his primary focus is Java on the Server-Side, i.e. Java Enterprise Edition. Prior to Oracle, David spent a decade at Sun Microsystems focusing on Java end-to-end (from the smart card to the high end server), related technologies and developer tools. In his various roles, David has been involved in numerous Java projects since the early days of this technology. 

David lives in Belgium. In his spare time, he enjoys playing video games with his daughter and tinkering with technologies such as Java, Home Automation, Electronics and Pinballs. You can find him on Twitter using @delabassee

That's it, remember to get your place through our MeetUp, thanks again to FibAlumni. We hope to see you all at FIB next thursday 21st at 7pm!
