Performance Tuning Clinic (22/11)

Eyy devs !!

Next Wednesday we'll host a very interesting type of event : a performance tuning clinic.

This will be a participatory session meaning bring your questions and don’t feel shy to provide answers to others questions. Even better, if you have (non-sensitive) performance data such as garbage collection logs, do bring it along. Topic can go in many directions from why MicroServices are a performance game changer to why immutability is the wrong solution to the right question.

This event will be conducted by Kirk Pepperdine.

After getting his start in the world if super-computing, Kirk went on to the world of Java eventually becoming a Java Champion in 2006 in recognition for his work advancing the state of Java performance tuning. Since then Kirk has co-founded jClarity, a company building the next generation of performance diagnostic tooling based on JPDM, a performance diagnostic process that he developed. Additionally, he authored and delivers the original Java Performance Tuning Workshop. Kirk has written many articles and spoken at many conferences on the subject of performance tuning.

Hope to see you there :)

En este caso coordinada entre varios JUGs de Latinoamérica y España, para que pasemos una jornada entretenida y práctica, jugando y probando las novedades de la última versión de nuestro (¿querido?) lenguaje Java.


Por supuesto, si es posible trae tu laptop o equipo portátil para practicar con nosotros, tendremos 5 horas de sesiones técnicas y ejercicios prácticos, que cubrirán entre otros temas la modularización de la plataforma y el uso de nuevas herramientas como JShell y JLink.

BarcelonaJUG at vJUG24 (25/10)

Hi devs!

Ready for our next session? We hope so because it's going to be next week on Wednesday 25th, again at Netsuite offices. As we did last year, we are going to attend to their virtual online presentations focused on Java (and other) technologies while sharing our points of views, discuss and in general have some interesting talks ;-) 

Our idea is to attend to the following sessions:

 
Once again, we have to thank to Netsuite, because thanks to them we will have the opportunity to organize the event in their beautiful offices and enjoy the food an drinks.



We will have opening the doors at 18'45 to start with the first session at 19h and finish around 21'30h.
Does this sounds interesting? We hope so! Also we will have the possibility to watch any other sessions (may be some video of the previous JBCNConf edition? ;-))

So, what do you think? Would you like to join us in person and share some knowledge watching the sessions while having free food and drinks? 

So, do not loose your time, and RSVPed now! Spots are limited!

See you next Wednesday! ;-)

Java & golang meets at Hacktoberfest! (19/10)

Hi devs!

Are you interested in contribute to open source projects? Really? Cool! Because we have an interesting opportunity to work on that, this Thursday 19th: we will collaborating with the Hacktoberfest ;-)

In collaboration with our friends from the Golang community and thanks to Netsuite, we will try to contribute to open source projects while enjoying a great evening (continue reading ;-)


Working individually or in small groups we will be contributing to open source projects while downing some great Oktoberfest beers and gorging on typical Oktoberfest wurst.

The event will start at 7pm with the coding contributions being presented to the group at approximately 9.30 pm, followed by a short presentation of a prize to the best contribution of the evening.

The aim of this event is to have a load of fun while giving something back to the open source community.

To suggest projects we can work on or issues you would like to fix, comment us, we will discuss and arrange it in advance ;-)

Prost and remember to RSVPed and join us for a unique evening combining open source coding with the joys of Oktoberfest!

Smarter testing and never waste time again.


Smarter testing and never waste time again.

The #1 programmer excuse for legitimately slacking off used to be “My code’s compiling”. 


These days it’s more likely “I’m running the tests”. We have time for a coffee (or two or three). That’s what we turn into code after all. 


We waste not only a lot of our time waiting until the very end of the build to see tests which we have just written failing, but also tons of resources making our CI servers sweat and having enormous queues of pending jobs. But what’s even more important - we switch contexts and thus we loose focus. 


Maybe we can test smarter? Join us in this workshop and bring your laptop to learn about a new tool we are working on that you stay in the zone and never waste time again. We know which tests you want to run.

Alex Soto, from RedHat will conduct this workshop . He's a usual speaker at the BarcelonaJUG events, as long as speaker in other big conferences like Devoxx, JavaZone, JavaLand, JavaOne...

Don't forget to register in our meetup event page, seats are limited.

DevOps for Adults: Setting up a holistic Continuous Delivery pipeline (12/9)

Hi dudes!
How are you? Hope all of you enjoy great holidays ;-)
We know that it is a bit hasty, but taking advantage that Michael Hüttermann will be the next week in our city, we have decided that it can be interesting to take advantage of his visit and just organize a talk with him (and start our particular back to school :-P ). 
Michael Hüttermann is Principal DevOps Consultant at CloudBees. He has written a couple of books including "DevOps for Developers", 2012, and "Agile ALM", 2011 and he was recognised to be a Oracle Java Champion in 2006 and a Oracle Developer Champion in 2017.

In this session we will interactively set up a holistic Continuous Delivery pipeline with the use of DevOps enabler tools, based on Cloud, microservices and container technologies. We’ll package a Java EE web application. Its development versions will be inspected and promoted towards production environment in the Cloud. Jenkins 2 with its native delivery pipeline features will serve as the major backbone of our DevOps toolchain glueing together other tools of the overall ecosystem.

So, sounds interesting for you? We hope to count with you and see you next Tuesday 12th at Codurance offices, so book your place in Meetup ;-)
Happy building!
PD: We haven't had time enough to announce this event in advance, hope you may understand... but we haven't notice the visit of Michael until the last minute :-/

Microservices development with Lagom

Hi devs !!!
Although we are finishing all the details for the JBCNConf , the JVM conference, that takes place next 19th of June, we don't stop organising events that we hope you will find interesting, with great speakers like Ignasi.
This time we've been lucky to host an event by Ignasi Marimon, about micro services and the Lagom framework next Thursday 8th of June at Ocado Technology offices.

"One microservice is not microservice, they come in systems" Jonas Bonér. With that premise in mind, Lagom is a framework that enables microservice-based systems development heavy-lifting the issues implicit in a microservices system. This session will be a 3 hour workshop where we'll review some opinions that affected the design of Lagom and we will also create a basic multi-service application. Please make sure to bring your laptop to follow along.
This is a hands-on workshop which requires some initial setup. Please follow the Getting Started guide for Java/sbt in the docs to make sure your machine is fully setup. 
As we have a limited space for this workshop, please register in our Meetup event.
Register !!!

Ignasi Marimón a well known developer, Software Craftman wannabe and coorganizer of the Scala Developers Barcelona group. Ignasi has a lot of background and experience developing in Java since 2001.
