We hosted the second edition of ‘IntelliJ IDEA Conf’, a free and virtual conference on the 29-30th of September, 2022, on IntelliJ IDEA’s YouTube Channel. 

Our intention with this event was to celebrate the developer community and its desire to learn and improve everyday. I hope we succeeded in this endeavor by hosting sessions by industry leaders and experts on a variety of topics, like Core Java, Kotlin, Spring, Kubernetes, JUnit, JavaFX, and contributing to open source projects. We also hosted sessions on using JetBrains IDEs to address the challenges of remote development, and learn about our brand new IDE – Fleet.

In this blog post, I’ll include links to the recorded sessions, presentations or other materials used by the speakers, our community partners and share a link to a few interesting tweets. 

Thanks everyone!

Let me start by thanking our amazing speakers for trusting us with their invaluable time and expertise and presenting with us. Special thanks to Donald Raab for presenting the keynote. Other outstanding speakers who accepted our invitation and presented on the first day are – Vitaly Bragilevsky, Anton Arhipov, Mary Grygleski, and Josh Long (listed in the order of their sessions).

We are thankful to all the speakers who presented with us on the second day of this conference: Nikhil Nanivadekar, Matt Ellis, Marc Philipp, Tomasz Nurkiewicz and Gail Anderson (listed in the order of their sessions). 

We are grateful to all the user group members and leaders who supported us by partnering with us. To me, every color, hue, tone or letters in the logos that these leaders shared with us represents the love and trust of you all in us at JetBrains. Here’s the collection of the beautiful logos of all the user groups and communities that partnered with us.

We thank everyone who participated in this event by viewing the online sessions, asking or answering questions, and sharing their learning or experiences with others. This event wouldn’t have been possible without your love and support.

Link to the recordings of the sessions hosted on this conference

I’m pleased to share that all the sessions we streamed live on this conference have been published on IntelliJ IDEA’s YouTube Channel. I’m including the link to all these sessions. Let’s start with the sessions presented on the first day of this event, that is, 29th September, 2022.

Keynote: Surviving Open Source, by Donald Raab

Open-source – we hear this phrase more often than before. But what does it mean to “contribute” to open-source projects? If you have ever contributed to an Open Source project, or lead and maintain one, you’ll know it isn’t easy to sustain it with personal and professional commitments.

Check out this event’s keynote by one of most amazing Java Champions, Donald Raab, creator of the OSS Java Library Eclipse Collections and an active open source contributor for over two decades. Learn from his story on how to survive contributing to open source – the road blocks, failures, challenges, collaboration, rewards and contentment. Click on this link to view the session slides.

Let’s Set Sail With Fleet!, by Vitaly Bragilevsky

Fleet is a brand-new lightweight distributed IDE from JetBrains. In this session, Vitaly demonstrated what Fleet is and how to use it. He covered Fleet’s main features, including working with many programming languages, and remote collaboration. He also talked about Fleet’s distributed architecture. If you are wondering about Fleet replacing IntelliJ IDEA, the simple answer is no. To find out all the answers, check out this session’s recording. Vitaly didn’t use any slides.

Should I Upgrade to Java 17?, by Nikhil Nanivadekar

Upgrading to a newer version of a language is not a simple decision. It depends on a number of factors that are specific to your application, team, deployment, user, and others. But every action, or lack of it, has consequences.

In this session, Nikhil provided the necessary data points and explanations to make a compelling argument for an upgrade from Java 8 or Java 11 to Java 17. He covered new Java features, demonstrated improvements, provided performance comparisons, and briefly discussed upgrade strategies. This talk hoped to help you make an informed decision on the question “Should I upgrade to Java 17?”. Click on this link to access the session slides.

Event Streaming and Processing Using Apache Pulsar, by Mary Grygleski

In this talk, Mary talked about how event streaming fits into the modern software development design and architecture, and some of the challenges it faces especially in the Cloud Native environment. She also talked about how developers could use Apache Pulsar, an open source platform, for distributed messaging and streaming, to create highly responsive applications with real-time capabilities.

Kubernetes Native Java, by Josh Long

How many times do you think – no matter what the topic is – if the speaker is XYZ, I will definitely learn and improve myself by attending the session. In the previous sentence, I could easily replace XYZ with Josh Long.

Josh live coded his session, demonstrating to developers how to use Spring and Kubernetes to develop fast, cloud-native, and scalable services.

Idiomatic Kotlin, by Anton Arhipov

In his talk, Anton highlighted how learning the best practices of Kotlin would help developers take its full advantage. He highlighted how it could be easy to start using Kotlin — it’s like Java, so your experience will easily let you start programming in Java style. However, to take full advantage of the language, learning Kotlin’s best practices is a must. Kotlin provides a number of features for writing concise and readable code. In this session, Anton talked about Kotlin features that make the programs look beautiful and more readable. Click on this link to view the session slides.

Wish You Were Here: Stories of Building a Remote Development IDE, by Matt Ellis

The world is witnessing a rise in the development teams, with a few or all remote members. This could pose a new challenge in terms of how organizations can help all their team members take advantage of the powerful machines that they own during the development stages.

One of the coolest developer advocates at JetBrains, Matt Ellis, addressed this and more. He talked about how JetBrains IDEs, such as Rider, IntelliJ IDEA and WebStorm, can run partially on remote servers and laptops, and still feel as if you are interacting with a local application. He also talked about features of collaborative code development in JetBrains IDES to help developers.

Evolving JUnit 5, by Marc Philipp

Testing is a crucial part of all applications and JUnit 5 is no stranger to Java developers. In this talk, Marc Philipp presented new JUnit 5 features such as declarative test suites, custom JFR events, new extension points, improved support for temporary directories, test method/class execution order, and the new XML reporting format.

Project Loom: Revolution in Concurrency or Obscure Implementation Detail?, by Tomasz Nurkiewicz

Project Loom has been in works for quite a long time at Oracle. Sections of this project have been accessible to the developers, such as the Virtual Threads, in Java 19, as a preview feature. Virtual threads are lightweight and have a low memory and scheduling footprint. They might revolutionize how you perceive blocking operations, Reactive frameworks and APIs, and develop concurrent code.

In this session, Tomasz covered Project Loom and its details. He also compared virtual threads to similar features in other JVM languages like coroutines in Kotlin, and talked about other challenges and solutions. This was an interesting session.

JavaFX for Mobile Development, by Gail Anderson

My first Java project was about developing a Java Swing application and it is difficult to look away when anyone talks about UI in Java.

In this talk, Gail Anderson talked about creating UI in Java, though using another library. She talked about the JavaFX toolkit and how it offers a powerful API. Gail covered how to create mobile applications that target both Apple App stores (iOS) and Google Play (Android) using the exact same JavaFX code base. Also, since JavaFX is Java, she showcased how developers can use the modern features of Java, such as lambdas, streams, records, and the new switch syntax.
