Java 9 Collections and Performance (17/5)

Hi devs!

Our next event is just around the corner! Thanks to our friends from Oracle Netsuite we will have the opportunity to play with Java 9 on an interesting workshop! ;-)

In this session we'll take a look at the new developer features that Java 9 delivers.

In particular, we'll look at Stream API improvements and see how our code can be substantially reduced. Finally, we'll benchmark it using JMH (Java Microbenchmark Harness) to analyze the impact the enhancements have on runtime.

Beers and snacks will be provided thanks to Oracle Netsuite.

Agenda:
19:00 - 19:30 Java 9 Streams API Overview
19:30 - 20:00 Dojo
20:00 - 20:15 Beer Break
20:15 - 20:45 Microbenchmarking

Remember to bring your own laptop, RSVPed and happy coding!

Sensorize your Life Workshop (31/5)

Hi devs!

Here we have our next event, this time a workshop to play with IoT and Arduino! Yay! ;-) Thanks to our friends from Netsuite we will have a great time playing with Arduino and the IoT. Also we will have a great time with drinks and food provided by Netsuite, so one more time, thank you to their support. Below you can see below the content and purpose of the workshop.

Nothing more, remember to RSVPed and have a nice coding and see you next 31th!

PD: Meanwhile we are working on the Java and JVM Barcelona Conference ( www.jbcnconf.com ) ! In the case you don't have your ticket, hurry up and buy your ticket! This year is going to be even better ;-) !

Abstract
---

The Internet of Things is a hot topic and is set to change how we live. But how much do you really know about it? This event demystifies the subject and shows you the potential of the technology.

In this practical workshop, you will learn about the basic concepts of the Internet of Things, discover how to connect a built IoT device, and push environmental metrics to a container-based monitoring platform deployed on Oracle Cloud Services.

At this workshop, you will:

• Program a mini board using Arduino, mastering the basic controls used to trigger actions in the on-board LED
• Connect a shield to detect temperature and humidity values
• Display data on an OLED display
• Send data to a persistent data store
• Push data to the cloud: Adafruit IO and Oracle Cloud Services

Topics covered:
---

• Introduction to the Arduino IDE
• Board installation
• Introduction to Arduino sketches and Hello World
• Basic LED controls: blocking, non-blocking and fade-in/fade-out
• Environmental sensor and display control
• Temperature & humidity output display and monitoring
• Push data collected to the Adafruit IO platform and to a container-based monitoring platform deployed on Oracle Cloud Services

Prerequisites & requirements

No prior experience required! Participants do need to bring their own laptops.
We recommend you install Arduino IDE beforehand. You can download the version for your OS here: https://www.arduino.cc/en/Main/Software

BarcelonaJUG at vJUG24 (27/9)

Hello devs!
Did you catch the HolidaysFinishedException()  ?

We hope so! ;-) 

We suppose all of you may know VirtualJUG, aren't you? Well, in any case, it is a great moment to know that there exist a Virtual JUG -usually managed by Simon Maple and Oleg Shelajev- and they hold interesting online presentations focused on Java (and other) technologies. 

They have planned a super 24h online session for the next Tuesday 27th and what we would like to know if you would like to join us to attend. You can have a look on the EMEA schedule: 

https://virtualjug.com/vjug24/ 

Btw, do not worry, we have plans to start around 18h-19h and finish at 22h. Does this sounds interesting? We hope so!

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? 

Finally, 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. 

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

See you next 27th! ;-)
