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!

Register in our event Meetup !!!!

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 OracleDavid 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!

Java Agents (27/4)

Hi JUGgers!

How's everything? Are you enjoying the spring? Get ready for the summer, in June we will have the 1st Java and JVM langs conference in Spain: JBCNConf!

Getting back to our events, April has become a great month for our events, and this year is not different: we have the pleasure to invite you to our next event focused on Java agents by Oleg Šelajev for the next monday 27th at 7pm at FIB thanks to FibAlumni.

Java agents are pluggable self contained components that run embedded in a JVM and intercept the classloading process. They were introduced in Java 5 along with the powerful java.lang.instrument package. Java agents can be loaded statically at startup or dynamically (programmatically) at runtime to attach to a running process in a fail-safe fashion.

Java agents were an awesome addition to the JVM as it opened a lot of opportunities for tool designers and changed Java tooling landscape quite drastically. In conjunction with Java bytecode manipulation libraries it is now possible to do amazing things to Java classes: we can experiment with programming models, redefine classes in runtime, record
execution flow, etc. In this session Oleg will give an overview of Java agents’ functionality along with the usage examples and real world experiences. We will learn, how to implement an agent and apply Instrumentation API in combination with bytecode manipulation libraries to solve interesting tasks. 

Oleg Šelajev is an engineer, author, speaker, lecturer and advocate at ZeroTurnaround. He spends his time testing, coding, writing, giving conference talks, crafting blogposts and reports. He is also pursuing a PhD on dynamic software updates and code evolution. Oleg enjoys speaking and participating in Java/JVM development conferences such as JavaOne, Devoxxes and others. In his free time, Oleg plays chess at a quater-grandmaster level, loves puzzles and solving all kinds of problems.

That's all folks! Remember to RSVPed and we hope to see you next monday!

¿Una base de datos como MongoDB pero con la fiabilidad y robustez de PostgreSQL? (24 y 25/04)

Hi devs !!!!

Aquí estamos, de nuevo al ataque con una interesantisima charla + workshop. En este caso sobre ToroDB PostgreSQL y NoSQL ), el próximo Viernes 24 de Abril tendremos la charla presentación y el Sábado 25 de Abril un workshop, ambos en La Fontana.
¿Te imaginas una base de datos como MongoDB pero con la fiabilidad y robustez de PostgreSQL¿Harto de que en tu empresa o clientes teman usar NoSQL y digan "sólo relacional"? ¿Te imaginas si se pudiera construir una base de datos NoSQL sobre la base de una excelente base de datos relacional? ¿Te imaginas un MongoDB durable, con lecturas consistentes, con transacciones.....?
¿Y si todo ello fuera open source? ¿Y si, además, fuera un desarrollo español, la primera base de datos creada por una startup española?

Pues bienvenido a ToroDB, una base de datos software libre, basada en PostgreSQL, y que implementa el protocolo de MongoDB, por lo que es compatible con cualquier herramienta de MongoDB. Y desarrollada por 8Kdata, startup española. En tu lenguaje favorito: Java.

Habrá una charla el próximo 24 de Abril ( Viernes ) para explicar las características de este software, cómo usarlo y qué ventajas aporta. Y al día siguiente ( Sábado ) 25 de Abril un workshop para amantes de Java donde parte del equipo creador de ToroDB detallará su arquitectura, estructura modular, librerías usadas en ToroDB y una apasionante sesión de hacking para resolver bugs, desarrollar nuevas características o simplemente aprender como funciona de manos de los creadores.

Álvaro Hernández, 36 años, Ingeniero de Telecomunicación, UPM de Madrid, es emprendedor y fundador de startups como Wizzbill y 8Kdata.

Apasionado del software libre y el mundo de las bases de datos, es el fundador y uno de los desarrolladores de ToroDB. Miembro de la comunidad PostgreSQL, es el fundador y Presidente del grupo de usuarios de PostgreSQL España, actualmente el 3er grupo de usuarios más grande del mundo de PostgreSQL. 

Álvaro es miembro también del grupo de Javaspecialists.eu y conferenciante internacional habitual. Y no se pierde ningún jCrete.org ;)

ToroDB ha sido presentado ya a nivel mundial en conferencias en Madrid, Moscú, Nueva York o India. Ha sido incluso presentado en las oficinas centrales de MongoDB en NY, ante el core kernel team.
