議程介紹

Java upgrades are sometimes seen as difficult and many applications are still running on an older version of Java. This session describes Java's current six months release process and why applications should use a recent Java version. After that, I'll explain the challenges of upgrading and provide some useful tips to make the process easier. Concrete examples (including solutions) will be used to show you how to upgrade your application to Java 17.

Koichi Sakata
Technical Lead

講者介紹

Koichi has developed many Java applications for 17 years. He wrote several Java books and is a frequent conference speaker in Japan. He was a founder of the JUG called KanJava and had managed it for over 10 years. Through the activity, he has interacted with java developers from all over the world. Now he is a Java champion. Last year, he started to contribute to OpenJDK. He had wanted to try to do this for a long time. He wrote some patches. They weren't certainly big or cool ones but were finally merged to OpenJDK. He loves to attend various Java conferences around the world!

議程介紹

Most developers have wanted to contribute to the OSSs that they have used in their daily work. But it is a challenge for everyone, especially the product that is big and famous like OpenJDK. I used to be the same. It's scary to send code that I write by myself to such a big community. Additionally, I'm not a native English speaker, so it's hard to explain my code in English. However, last year I send several patches to OpenJDK at last. They weren't elegant or cool. I made some mistakes in them, but people in the OpenJDK community properly pointed out those mistakes. When my patches were finally merged, I got fulfillment that I've never felt before. In this session, I will talk about how to start to contribute to OpenJDK and my experiences. Even if you aren't an experienced java developer, you can contribute. In addition, the OpenJDK repository moved to GitHub and changed the development method to pull request based one. It is easier to contribute than before. After this session, you will be able to start contributions!

相較於單元測試，整合測試能夠有效幫助我們確保不同元件間互動的正確性。而在撰寫整合測試時，可能會用不同方式建立測試環境，但有些測試環境可能不容易建立，或測試時容易受其他因素影響導致測試失敗。 Testcontainers 是一個支持Junit的Java library，它提供了常見的資料庫，Selenium Web瀏覽器或其他可以在Docker容器中執行的輕型的一次性實例。
在這場分享，會簡單介紹整合測試及Testcontainers 並跟大家分享我們改用Testcontainers的經驗以及它帶來的好處

This presentation will focus on what specific Algorithms that are inside Oracle can be applied to Business Problems. Robots may be the first to truly learn Machine Learning (ML) and expand into Artificial Intelligence (AI).

議程介紹

Forget about Machine Learning. Planning optimization is the most profitable AI technology on this planet. The world is full of planning challenges, such as vehicle routing problems, maintenance scheduling and employee rostering. Find the quickest routes to visit n locations with k vehicles. Or assign shifts to employees, taking into account skills and availability. Few people realize how much AI algorithms improve those solutions. For example, when telco’s started using OptaPlanner to plan their fleet of technicians, many expected a driving time reduction of 1-2%. It was 25%. In some cases, that saves hundreds of millions of dollars and millions of kilograms of CO² emissions, every year. In this session I’ll show you how to code a highschool timetabling application, with Quarkus and OptaPlanner (both open source). It ‘ll generate the perfect lesson schedule, for both students and teachers, taking into account hard and soft constraints.

議程介紹

Your project has reached that stage when it’s a good idea to post binaries, but new questions appear such as where should they be posted? How do make it easier for users to install and discover your binaries? Where should releases be announced? Most importantly, can answers to these question be automated? Enter JReleaser, a tool that provides answers to these questions and more. JReleaser may be used to create GiHub/GitLab/Gitea releases and publish binaries that can be consumed from different distribution channels such as Homebrew, Snap, Scoop, and more. Once published, the release cab be automatically announced on Twitter, Slack, Gitter, Discord, and other communication channels. Come to this session to learn how JReleaser can help you release, publish, and announce binaries with ease, and fast!

在2016年時我們介紹了當時還是0.28.0.Final的 Armeria，過了五年後的現在 Armeria 經歷了1.0後來到了1.13.1。這幾年陸陸續續增加了不少新功能和改進，像是更完善的gRPC支援，更方便與Kotlin和Scala整合以及與 Spring Boot 搭配使用等等。除了在LINE內部，我們也看到有其他開源專案和公司開始使用 Armeria。
這個議程將透過要建立一個新服務需要哪些功能的觀點，帶大家走過 Armeria 原本有的以及在這幾年新增和改善的功能。說不定在某些情境下，Armeria 會成為你們專案中一個合適的選擇。

議程介紹

ECS (Entity Component System) is a well-known pattern in both the game engines and UI frameworks. Scala 3, with its many new meta-programming features, are well-suited for ECS construction. In this talk, I will present a minimum ECS by utilizing language features of Scala 3 and explain some of the intricacies of the implementation. It should not be too difficult to follow along. Skimming through the ECS article on Wikipedia might be beneficial prior to the talk. By utilizing Scala's sophisticated type system, the ECS features, even though minimum, are both type-safe and user-friendly. It is my belief that a good computer language should be able to minimize program mistakes and maximize program performance, and I think Scala 3 delivers on both promises splendidly.

After 3 years, the third LTS version, Java 17, was released in September 2021. We all are very excited and keen to learn more about new changes it brings to us. However, many projects and products are still using Java 11, or even Java 8. In this session, we will not only focus on those amazing features, but also have a quick introduction on why we should migrate to Java 17 and how.
