This fast-paced, demo-driven, entirely slide free session will show you the many ways of effectively deploying a Jakarta EE application to Azure. We will start by deploying a local Jakarta EE application to basic IaaS on Azure. We will then deploy the same application to an entirely managed Azure PaaS. Finally we will deploy the application to Azure using Docker and Kubernetes. We will discuss the trade-offs of each approach on the way, offering guidelines for which approach might be best for your application on the cloud. At the end of the session, you will have all the demos on GitHub so you can explore them on your own.
This session is a fast-paced tour of all things Java and Azure at the modern Microsoft of today. We will first talk about the why, how and what of Java and Microsoft. We will then dive right into the broad range of tools, services and APIs that Microsoft offers around Azure for Java developers. We will show a small but representative demo of a Java application most developers would feel familiar with running well on Azure. Lastly, we will discuss the road map for what Java developers can expect from Microsoft in the future. This session is as much about sharing what Microsoft offers today as it is about listening to what the Java community wants to see from Microsoft tomorrow.

Java Byte code is OS independent, which means that your application’s startup takes more time than a native image. Using the Class Data Sharing functionality introduced in more recent versions of the JVM, you can prepare your application so that it will load very fast.

How well tested is your system? How do you measure it? Code coverage can give you the answer, however can we trust our unit tests? Trust me or not, but I used to work for the investment banking industry in a big project where a lot of unit tests had no assertions (!). And yes… the coverage was very high.
Mutation testing is a method to check the quality of your unit tests and show more reasonable code coverage reports. In this session I will describe the idea of mutation testing and show a live example with the use of PIT Mutation Testing framework.

While a microservices architecture is more scalable than a monolith, it has a direct hit on performance.

In this demo-based talk, I’ll show how Hazelcast In-Memory Data Grid can help you in each one of those areas and how to configure it. Hint: it’s much easier than one would expect.

Stefan, like most geeks, rejected the faith of his parents early in his childhood. Later in life, however, he missed the community support and sense of purpose that religious people enjoy – until he found Pastafarianism.
He converted to his new faith in 2009 and has spearheaded the Bulgarian branch of the church ever since. In 2016 Stefan and his now wife became the first couple in Bulgaria (and only 2nd in the world) to have a Pastafarian wedding ceremony, a rite they now recommend for everyone who finds the traditional church wedding boring and misogynistic.

Our robotics club is a town team. It is five years old, with kids from the first to twelfth grade. A student from the sixth grade invented the name of the team while watching the keyboard of the computer. These are the first letters of the left upper part of the keyboard. We gather together twice a week and work in groups. We do LEGO-robotics. We first construct robots and after that we program them for specific tasks and missions to help people. During the meetings we work and have fun. We often play team games or compete with the robots that we constructed. Once a month we organize sumo fights. On celebrations we take part with our robots. We like to show the constructed by us mechanisms and the programmes to students from our and other schools. It happens when our school celebrates.

#SpoDari (от спортувай и дарявай) е идеята ни за това как можем да съчетаем спорт и добра кауза. Всички имаме нужда да се движим и спортуваме.
Движението ни зарежда, движението ни мотивира, движението ни прави по-усмихнати и позитивни. А ако работното и домашното ни ежедневие
не ни раздвижват достатъчно, трябва да се постараем, за да сме жизнени и здрави.
