Croatian Java User Association (HUJAK) is organizing one of the largest Java community conferences in this part of Europe. Our intent is to gather the majority of Java community in Croatia as well as from this part of Europe, and we also warmly welcome a lot of speakers and visitors from all over the world.

Call for Speakers is open until January 6th (extended final date)!

Dear Speakers, this is a great opportunity to tell your story, share your experience, show your results and promote your product, your company and yourself in front of other developers, software architects, and project managers, as well as media representatives, potential partners and clients. As a place of intense social networking, it may also be a natural way not only to discuss your projects and trending technologies but also to seek for new employees or find a new job in 2017!

We invite you to help us build a great conference once again and submit your talk or workshop proposal (extended final date January 6th) to get a chance to become one of the speakers at Javantura conference. If you think there is something interesting that you want to share with the rest of the community – please submit. Additionally, we strongly encourage HUJAK members to submit talks proposals – this is the easiest way to show your achievements to your community.

Proposed conference tracks include:

• Core Java, Frameworks, and Servers
• Web and Mobile Development 
• Methodologies and Tools

Real-time BigData ingestion and querying of aggregated data – Davor Poldrugo

View data in real time in Big Data environment is becoming more and more challenging. Classical transactional systems and data replication encounter more obstacles in Big Data environment. One of those obstacles is large latency between time when data entered in the system and time when data is ready for querying. In this presentation will be shown the path that Infobip has chosen to try to achieve real time in Big Data environment. Keywords: Lambda architecture, Redis.io, Apache Kafka, druid.io.

HUJAK’s CroDuke Indy presents video and slides from Javantura v3 conference presentation:

The Internet of (Lego) Trains – Johan Janssen, Ingmar van der Steen

Last year we thought about starting a new Internet of Things project. In the end we decided to use Lego and Raspberry Pi’s to create The Internet of (Lego) Trains. There were multiple reasons for this project. We wanted to learn more about these technologies, get non-technical people and children excited about electronics and programming and have an excuse to play with Lego. The Lego trains are equipped with a Raspberry Pi, camera, wireless dongle, infrared transmitter, speaker, RFID reader and battery pack. Next to that we have automated switch tracks again with the help of a Raspberry Pi. To view the entire track we also have an overview camera connected to a Raspberry Pi. To control the trains and other parts we built a Java and AngularJS application. The Java application uses Jersey for the REST endpoints and connects with the different components. For some functionality the Java application calls C and Python code so we didn’t need to write and maintain that functionality ourselves. The application supports both manual control of the train and autopilot functionality. In this session we will explain how you can build your own Internet of (Lego) Trains. Next to that we will talk about our experiences and challenges and of course we will give a live demo!

Video (Javantura v3) – Just say it – using language to communicate with the computer – Hrvoje Šimić

Just say it – using language to communicate with the computer – Hrvoje Šimić

We are used to give commands to our computers with mice and keyboard shortcuts – even though, as programmers, we know how we can be expressive with text. Could we be more effective if we communicate with computers using language, be it natural or artificial, typed or spoken? Through examples of real-world products we’ll demonstrate the power and usefulness of verbal user interfaces.
