Essential Test-driven Development
為了解決javascript this 的問題,作者Myers, Robert C. 這樣論述:
Test-Driven Development (TDD) is at the heart of low-defect agile software development, enabling incremental development and emergent design without degrading quality. By allowing software teams to create comprehensive regression tests that immediately pinpoint tiny errors, it gives them confiden
ce to enhance functionality with incredible speed.Essential Test-Driven Development will help you discover how TDD helps developers take back the joy of software development, as you glimpse of the future of TDD and software development as a profession. Leading TDD coach and instructor Rob Myers shar
es his experiences, suggestions, and stories, plus focused and fun self-directed Java, C#, C++, and JavaScript lab work from his acclaimed TDD course. Throughout, this guide reflects the author's unsurpassed experience practicing TDD on real production code and helping hundreds of teams adopt TDD pr
actices. Myers addresses both human motivations and technical challenges, and stresses benefits to individual programmers, not just companies. He also offers exceptional coverage of massive refactoring and legacy code, reflecting the actual realities most developers face.

基於網路化監控系統於發光二極體之功率控制及其數據化分析的時間序列設計模式
為了解決javascript this 的問題,作者蒲里亞 這樣論述:
發光二極體(LEDs)的技術品是有節能效益、照度優、效能優、長壽命優,而被認為是許多光源應用中最佳來源之照明。然而影響LEDs的最大問題所在就是其壽命週期,包括LEDs的光效能下降或突然失效,而不穩定的正向電壓、不足的限制電流和高溫會導致LEDs光衰退的發生。所以能夠即時監控LEDs參數物理變化,以及在特定條件之下控制LEDs的功率及是減少光衰退的方法之一。本論文研究是基於應用Web的網路便利性方式來構建時間序列之參數監控化系統和一個LEDs電源控制系統,以樹莓派(Raspberry Pi)和ESP32作為系統的主要設備。為了讓系統介面給使用者方便來應用,建構兩個用戶界面(UI),以及參數數
據存取方式和方便管理時間序列之資料庫數據,作為測量物理變化和執行動作由ESP32和ESP8266處理,並將傳輸和執行設備鏈結到系統,而蒐集數據與存取並藉由無線網路鏈結傳遞到Raspberry Pi,以完成更好的移動性與遠程使用MQTT發布/訂閱消息連接協議。因有Web的網路應用程序於即時監測和控制,任何設備可透過Web網路瀏覽器查詢。監控UI使用TIG (Telegraf, InfluxDB, and Grafana)堆疊技術,這是一個平臺的字體縮寫,對時間序列之參數與資料庫數據進行擷取、儲存、繪圖和警示。另外對電源控制UI是基於Web網路之應用方式來做使用HTML語言與Javascript構
建之程式,透過改變LEDs功率進行測試與實驗調整。實驗發現LEDs的驅動器能夠對LEDs使用者提供從0 V到22 V的電壓範圍設定和0 mA 到2,000 mA的電流範圍設定。
JavaScript for Sound Artists: Learn to Code with the Web Audio API
為了解決javascript this 的問題,作者Turner, William,Leonard, Steve 這樣論述:
Learn how to program JavaScript while creating interactive audio applications with JavaScript for Sound Artists: Learn to Code With the Web Audio API! William Turner and Steve Leonard showcase the basics of JavaScript language programing so that readers can learn how to build browser based audio
applications, such as music synthesizers and drum machines. The companion website offers further opportunity for growth.Web Audio API instruction includes oscillators, audio file loading and playback, basic audio manipulation, panning and time. This book encompasses all of the basic features of Java
Script with aspects of the Web Audio API to heighten the capability of any browser. Key FeaturesUses the readers existing knowledge of audio technology to facilitate learning how to program using JavaScript. The teaching will be done through a series of annotated examples and explanations. Downloada
ble code examples and links to additional reference material included on the books companion website. This book makes learning programming more approachable to nonprofessional programmers The context of teaching JavaScript for the creative audio community in this manner does not exist anywhere else
in the market and uses example-based teaching
基於運行環境事件之程式行為萃取及其應用
為了解決javascript this 的問題,作者李泓暐 這樣論述:
由於電腦科技逐漸在各處都可見其身影和日益複雜的電腦系統,了解那些在電腦系統中的程式行為無可避免地成為一個重要的議題。鑒於在沒有程式輸入下僅靠程式原始碼來分析程式是有困難的,又或者靠程式機器碼,但即使是一個簡單程式,其機器碼也相當複雜而難以分析,本篇論文轉而藉由觀測那些在程序(運行中的程式)所觸發的事件來分析程式行為。雖然那些事件自然地蘊含了許多關於該程式的資訊,但相對的,種類繁多的事件語意和格式仰賴於執行環境,若要有較好的偵測效率或效果,將使得觀測或分析時期的優化需要大量的專家知識。除此之外,一次大量的事件或是快速的事件生成速率(尤其是在觀測低階事件)皆會限制其線上應用。本篇論文將提出兩個程
式行為模型涵蓋了三種不同面向的程式行為,這些行為在現今環境都有非常廣泛的應用。流域模型(Watershed model)針對程式計算量和並行性,而輪廓模型(Profile model)針對程式功能性,而且這些模型的輸入能夠非常簡單地從真實系統事件中進行對應,不需要大量專家知識以及完整的事件語意。為了證明這些模型的實務價值,本篇論文實作了兩個雛型系統分別基於其中一個模型在效能分析和安全應用上,並且進行充分地評估。
