講者介紹

Chad Arimura a 3x entrepreneur, most recently as co-founder and CEO of Iron.io where we grew a multi-million dollar ARR business helping pioneer serverless computing including some of the earliest usages of the term "serverless" in 2010. We sold the company in 2017 and joined Oracle. On joining Oracle as Vice President of Serverless, Chad established the serverless organization, under which produced The Fn Project and later Oracle Functions, making Oracle one of the only major clouds to offer a functions-as-a-service platform largely built on upstream open source code. Once the serverless org was fully established, Chad moved to the Java Platform Group to help build out the developer relations team.

議程介紹

This year, as we celebrate the 25th birthday of Java, it remains one of the most pervasively-used technologies in our lifetime and continues to advance the application world around us. The technology landscape is changing at an ever-increasing pace, and Java is thoughtfully evolving to address new opportunities while staying true to its roots in compatibility.
In this keynote, Chad Arimura and Sharat Chander will talk about how Oracle’s ongoing stewardship of the Java Platform offers sustained innovation and addresses modern Java application development. They'll cover the recent changes in the release cadence, investments in the ecosystem, and many important language and platform features released since Java 8, as well as a look into the future of how Java is innovating through initiatives like Project Loom for reinventing the threading model, Project Panama for better interfacing with native code, Project Amber for writing better, less error-prone, concise and expressive code, and more!

RSocket is here! RSocket is a binary, reactive, and operations-friendly wire protocol that integrates that builds on top of Project Reactor. Engineers originally developed RSocket at Netflix. Then they moved to Facebook. RSocket was the fledgling project for the Reactive Foundation, of which the spring team, Lightbend, Facebook, Alibaba, and others are founding members. RSocket represents the operational insight of some of the largest organizations in the world. And, it readily integrates with Spring. Join me, Spring Developer Advocate Josh Long (@starbuxman) in this rapid, reactive ride on the RSocket rocket, and we'll look at the rich Spring support for RSocket and its use in building faster, more robust and more scalable services.

- How to build RSocket-based controllers in Spring Framework
- Build RSocket clients using the `RSocketRequester`
- How to use the `rsc` client
- Build processing pipelines using Spring Integration
- Secure our services with Spring Security
- Introduce bidirectional communication
- and more!

Do you repeat your validations on every protected endpoint to be sure that the user can access to it ?
Do you populate the audit properties of your entities like “updated_at”, “deleted_by” by hand on every change?
Want to standarize your error responses?
In this session we will discuss how your development can be more easy and fun after you extract all of that common code using Filters, Listeners or Interceptors and apply them to your code just using annotations.

Kotlin Flow is an asynchronous stream library based on top of Kotlin Coroutines. There are different ways to use Flow and test them on Android. In this talk, we will discuss the applications of Flow and their pros & cons. For example, we can also apply with Flow on UI events and network requests. As you may know, unit testing on Android sometimes could be painful. We will go through Flow testing methods and examples to let you get familiar with them. In the last part of this talk, we will talk about the experience and pitfalls of using Flow in production.

在 Java ecosystem, 資料庫應用系統通常會使用 JDBC 直接存取資料庫, 或採用其他 ORM framework 資料庫存取工具.
Quill 是 Scala 的一個簡單又優美的 ORM 工具, 它提供了一組 DSL(Domain Specific Language). 只要使用 case class 加上 function, 我們即可使用 Scala 語法寫出優美的資料庫查詢指令. 在 compile-time 階段產生出對應資料庫的 SQL statement, 也因此在 run-time 階段, 系統不再須要動態組出 SQL statement, 提升了系統整體的執行效能.

議程介紹

Type-level programming is programming with types. Not many computer languages that are in common use today have type systems sophisticated enough to support type-level programming but, fortunately, Scala is one of them. With the help of some new language constructs and standard library features, type-level programming is becoming even more accessible and intuitive in Scala 3. In this talk, we will go through some of the new language constructs that supports type-level programming and touch on the library features that makes use of those constructs. Type-level programming might sound elusive to most of us but it doesn't need to be. Many type-level guarantees translate directly to the correctness of our programs and enable us to catch bugs even before running the program. We hope this talk will illustrate the usefulness of type-level programming in Scala 3 and open the door to your future type-level programming endeavours.

程式設計師，開發過售票、身份驗證、廣告競標、語音辨識等各式各樣的服務。興趣是透過各種工具與技術開發可觀察、可維護的分散式系統，讓維護者能多睡點覺。

議程介紹

隨著軟體服務的成長，多數系統透過分散式系統（distributed system）來提高系統效能、方便維護、提高擴充性。然而分散式系統的除錯、監控、維護一直是相當複雜的問題。許多特別的 race condition 與效能瓶頸更是只會在 production 環境中出現，讓開發者更加頭痛，也影響了用戶體驗。
本次分享將會：
1. 開發 production-grade distributed system 需要知道的基本觀念。
2. 如何設計出可觀察（Observable）、可維護（Maintainable）、可測試（Testable）的分散式系統。
3. 透過基於 Clojure 的 Jepsen 框架（https://github.com/jepsen-io/jepsen）測試分散式系統的經驗分享。

目前任職於國泰金控數數發(DDT)，多年JVM相關語言開發經驗，熱愛學習與分享新技術，立志成為技術佈道師，目前專注於Microservices、Event-Driven Architecture & Cloud‐native application development

議程介紹

這幾年來Microservices Architecture已被各個企業所採用並實際用於軟體架構設計與開發; 在Java語言中，Spring Boot與Spring Cloud是最廣泛使用的Framework，雖然比過去Spring Framework有相對的改良，但其開發與建制部署在K8S platform還是有一定的複雜度。
因此，RedHat在2019/11正式發佈Quarkus，其是一個Kubernetes-native的Java Framework，其採用container-first的理念來設計，更容易部署在不同的K8S相容的平台，並可以快速開發出不同cloud-native服務，例如: event-driven, serverless等。
本次主題會講解Quarkus核心概念，與cloud-native apps開發方式，並且會有demo讓大家能更快瞭解。
