Novi Java Champion – Simon Ritter

Prenosimo vijest o novom Java Championu – Simonu Ritteru i pridružujemo se čestitkama.

Simon Ritter has been involved in promoting Java since the release of the first official JDK, when he joined Sun Microsystems in February 1996. He started helping to drive Java adoption back in 1999 as part of Sun’s Market Development Engineering group and moved to full ­time evangelism in January 2001. He also helped to start the Java Champion program. He has been in the IT business since 1984 and holds a Bachelor of Science degree in Physics from Brunel University in the U.K.

In his time at Sun/Oracle, he presented at almost all of the main Java conferences and many of the smaller ones. He has delivered Java presentations in 56 countries on six continents. In that time, Simon covered a wide range of subjects covering the launch of all Java SE versions since 1.4, Java EE, web services, SOA, Cloud, Java ME, embedded Java and JavaFX. 

At Oracle Simon took over managing the Java Evangelism team for the core Java platform, Java for client applications and embedded Java. Now at Azul, Simon continues to spread the word about Java and has become involved in new activities like the JCP Executive Committee.

Ritter has written many articles, been a track lead several times for JavaOne content reviews and created training courses like the JDK 8 Lambdas and Streams MOOC, which had 10,000 people sign up for it. He writes a Java focused blog, which can be found at azul.com/blog. Follow him on Twitter @speakjava

Java Champions are an exclusive group of passionate Java technology and community leaders who are community-nominated and selected under a project sponsored by Oracle. Learn more about Java Champions.

Aktivnosti Oracle Academy u Hrvatskoj

Prenosimo vijest iz Oracle Academy Newslettera za svibanj 2016. u kojem su opisane aktivnosti našeg partnera, lokalnog ogranka Oracle Academy, pod vodstvom Darka Jurekovića, koji uspješno surađuje s HUJAK-om.

Vezana vijest: prvi Oracle Academy dan u Hrvatskoj

Croatia Focuses on Computer Science Education

0516-world1-smCroatia is advancing computer science by introducing Oracle Academy across its schools nationwide. Since the first Oracle Academy Day event in February, Oracle Academy has been introducing educators and students to core academic computer science curriculum, leveraging vendor neutral tools and industry-leading Oracle technologies, to help make a difference in their long term education and potential career pathways.

Keystone Events

On February 12, 2016, the University of Zagreb, Faculty of Electrical Engineering and Computing hosted an Oracle Academy Day event with Oracle Academy to bring into focus the topic of Big Data, exploring the demand for data-oriented professionals across a wide range of industries, organizations, and disciplines, and the unprecedented use of technology to support data-driven decision-making. Twenty-two additional institutions from Croatia, Bosnia, and Herzegovina joined the event via live-streaming.

Throughout March, Oracle Academy continued to support the momentum of Croatia’s focus on computer science education. On March 14–18, 2016, Oracle Academy organized Java Foundations training for educators from Croatia, Bosnia, and Herzegovina at the University College Algebra, Croatia. “The main value of Oracle Academy courses to us is providing students with knowledge and skills that increase their employability by making them more attractive for prospective employers in the IT industry,” Frane Urem, Ph.D, Vice Dean, Senior Lecturer, Polytechnic of Šibenik, Croaita. The next Java Foundations training is scheduled for May 9–13, 2016, at Faculty of Sciences, Split, Croatia.

On March 16, 2016, the e-Skills for Jobs initiative in Croatia was presented to the President of Republic of Croatia, Kolinda Grabar Kitarović, another significant milestone to increase STEM studies in Croatia. Grabar Kitarović supports the initiative because the current number of computer science graduates in Croatia does not meet the demand of the local IT labor market. The e-skills initiative will help contribute to the IT industry growth, provide a more stable labor market, and create the opportunity for Croatia’s global competitiveness in the IT sector. Oracle Academy is proud to be a member of this initiative to help more graduates enter the growing IT labor market.

On March 21–25, Education and Teacher Training Agency (ETTA) organized a national programming competition for K-12 students to coincide with the annual ICT conference. Computer science teachers from primary and secondary schools joined the event in Primošten, Croatia. Students competed in three categories of algorithms, IT basics, and application development. The winners were invited to represent Croatia at the International Olympiad in Informatics. Oracle Academy supported the conference and provided awards for the National Finals’ competition winners.

Ongoing Education

Oracle Academy will continue to support Croatia and its Oracle Academy members through a variety of free trainings for continuous learning and development of educators, including Alice and Greenfoot workshops. The workshops are ideal for teachers who have never taught computer science or for those experienced computer science educators who want to refresh their skills using the tools and techniques employed in our courses.

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.

ES6 – Future Is Now – Nenad Pečanac

EcmaScript6 or ES6, also known as Harmony, is the latest specification of the language, finalized in June 2015. Six years after the ES5, ES6 presents a significant update with numerous improvements and new features, setting a solid foundation for future 12 month release cycles and forthcoming evolution of the language.

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!

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.

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

Spring Boot under the cover – Nicolas Fränkel

Spring Boot is a stack enabling you to kickstart your Spring application in a matter of minutes. It has been a resounding success among both developers already using Spring and microservices adopters. Favoring Spring Boot over the traditional Spring framework comes at a cost, though: you have to let Boot in control and some like to know everything what happens. Come to this talk to discover about auto-configuration and the different flavors of conditionals. After this talk, you’ll be able to understand Spring Boot internals and develop your own starter dependency.
