In Rosie Young: A Lifetime of Selfless Service, Moira Chan-Yeung presents a brief history of Professor Young’s remarkable career in medical education and administration at the University of Hong Kong (HKU) and her wide-ranging public service to the community over many decades. As the first female dean of HKU’s Faculty of Medicine, her career was deeply intertwined with the socio-economic development of Hong Kong. After her retirement from HKU, she continued to serve HKU and the community up to the present. This book illustrates her many contributions to the development of medical education in Hong Kong and to the university administration at HKU. Professor Young’s extensive public service in the field of medicine also helped improve primary care, hospital care, and public health in Hong Kong. In short, this book provides a valuable record of a female giant in Hong Kong’s medical history and documents her selfless and enduring service to the HKU community and Hong Kong society.

《Spring Boot in Action》是一本專為熟悉 Spring Framework 的開發者所寫的實戰指南，聚焦於如何運用 Spring Boot 大幅簡化 Java 應用程式的開發流程。Spring Boot 以「約定優於設定」為核心理念，讓開發者跳過繁瑣的組態工作，快速啟動專案，將心力集中在應用程式的行為與商業邏輯上。作者 Craig Walls 以多年 Spring 開發與教學經驗，透過清楚且實用的範例，說明如何有效運用 Spring Boot 的自動組態機制，同時在需要時進行客製化調整。書中涵蓋測試、部署、Actuator 監控、命令列工具（CLI）、以及與 Groovy、Grails 的整合應用，完整呈現 Spring Boot 在實務開發中的優勢。本書內容務實、節奏明快，適合希望提升開發效率、減少設定負擔的 Java 與 Spring 開發者閱讀，是理解與上手 Spring Boot 的重要入門與進階參考。Although Spring Framework simplifies enterprise Java development, it can require a lot from developers in terms of framework configuration. Spring Boot radically streamlines the process of creating Spring applications by employing automatic configuration, along with a programming model built around established conventions for build-time and runtime dependencies. It also provides a component that gives insight into the internals of a running application and a handy CLI that can be used to write command-line scripts in Groovy. Developers who have used Spring Boot say that th

The origins of the F-35 and the amazing challenges the industry had to be overcome go back to a still-secret NATO study that evaluated the vulnerability of air force bases in the West.This spurred development for Short Take off and Vertical Landing (STOVL) fighter aircraft. Only two aircraft with this capability actually entered service, the British Harrier and the Russian Yak-38. However, these aircraft lacked supersonic capability which made them vulnerable to faster fighters. So a programme was initiated for a supersonic STOVL fighter - but the trail of unsuccessful efforts was long. NASA, as well as the defense Evaluation and Research Agency and private industry, studied advanced STOVL propulsion ideas but without tangible result. It was only when the Defense Advanced Research Projects Agency, at the request of the Marine Corps, issued study contracts for a supersonic STOVL fighter to American industry that real progress began to be made.It was Lockheed Martin that came up finally
