"A top-notch literary brainteaser." -New York TimesSoon to be a major motion picture sequel to Murder on the Orient Express with a screenplay by Michael Green, directed by and starring Kenneth Branagh alongside Gal Gadot--coming September 17, 2021 Beloved detective Hercule Poirot embarks on a journey to Egypt in one of Agatha Christie's most famous mysteries.The tranquility of a luxury cruise along the Nile was shattered by the discovery that Linnet Ridgeway had been shot through the head. She was young, stylish, and beautiful. A girl who had everything . . . until she lost her life.Hercule Poirot recalled an earlier outburst by a fellow passenger: "I'd like to put my dear little pistol against her head and just press the trigger."

思想、脈絡與觀念理解是真正的專業技術門檻，也是鑑別出實力強大或平庸工程師的關鍵區別之一。 本書內容改編自第 14 屆 iThome 鐵人賽 Modern Web 組的冠軍系列文章《一次打破 React 常見的學習門檻與觀念誤解》。本書以循序漸進的脈絡帶讀者從頭理解 React 技術的核心觀念、運作原理與設計思維。 React 本身的設計基於了許多程式領域的設計模式，而這些設計模式的概念大多都與「還沒有使用前端框架時的程式運作思維與習慣」相去甚遠。因此當你沒有真正理解這些設計模式時，你會覺得 React 的許多設計與行為都很不直覺甚至莫名其妙。並且，如果你不熟悉這些觀念或原理的話，則非常容易在實際開發時寫出有問題但卻不自知的程式碼，為專案的程式碼品質和軟體產品的可靠性埋下巨大的隱患。 有別於市面上充斥的各種「教你如何呼叫語法」以及「帶你實戰範例」的 React 學習資源，本書會著重於技術理解的基本功累積，讓你對於 React 的觀念不再一知半解，以避免「跟著寫了很多 React 範例練習卻還是不懂這些程式碼是如何運作的，無法真正掌握這門技術」這種常見的學習瓶頸，帶你朝向真正的專業 React 開發者邁出紮實且關鍵的一大步。 目標讀者 本書並不是一本關於如何開發 React 專案的手把手實戰教學手冊。相較於大量的案例實作練習，本書會更聚焦於 React 的核心設計思維以及最常被誤解的觀念進行透徹的解析，希望能夠幫助大家一次打破 React 的學習門檻與觀念誤解，成為真正的專業 React 開發者。這本書適合所有「希望將 React 作為專業技術能力」的人學習： ❏ 適合有 JavaScript 的基礎，但對 React是完全新手的人。你可以透過本書從零建立相當穩固的 React 核心觀念理解與思維的基本功，對於後續繼續學習其他實戰類型的學習資源也能有更好的基礎進行銜接。 ❏ 也適合已經在學習 React 中的人。這本書將可以讓你對於許多觀念的理解茅塞頓開，學習成效事半功倍。 ❏ 也適合對 React 有一定程度的認識或實作經驗，但對於核心觀念與原理還沒深度掌握的人（應該有蠻多人是處於這個階段）。這本書會是你突破瓶頸、邁向資深 React 開發者的關鍵助力。專業推薦 「這本書使 React 初學者能夠打破「只會跟著寫範例但不理解背後原理」的惡性循環，進而

Winner of the 2020 Costa Book of the year, The Mermaid of Black Conch spins the enchanting tale of a cursed mythical creature and the lonely fisherman who falls in love with her. In 1976, David is fishing off the island of Black Conch when he comes upon a creature he doesn't expect: a mermaid by the name of Aycayia. Once a beautiful young woman, she was cursed by jealous wives to live in this form for the rest of her days. But after the mermaid is caught by American tourists, David rescues and hides her away in his home, finding that, out of the water, she begins to transform back into a woman. Now, David must work to win Aycayia's trust, while she re-learns what it is to be human, navigating not only her new body, but also her relationship with others on the island, a difficult task after centuries of loneliness. As David and Aycayia's love grows, they navigate both the joys and dangers of life on shore. A lingering question remains: will the former mermaid be able to escape her curse

內容介紹: 不同於常見機器學習皆是由 Python 語言實作, 本書使用 JavaScript 語言於瀏覽器實作機器學習, 搭配著名的 JS 機器學習函式庫 ml5.js 可以更快速且便利地達成 AI 網頁應用, 對於許多熟悉 JS 語言的前端工程師或使用者更為親近, 實驗過程使用 p5.js 程式庫, 讓沒有太多程式設計基礎的使用者也可以更輕鬆將結果視覺化, 再搭配使用 p5.js web editor 線上開發環境, 只需要使用瀏覽器就可以開始輕鬆設計網頁, 不需要在自己的主機建構繁瑣的開發環境, 再搭配 Python 編寫控制板程式, 將應用結合至感測器或實體輸出裝置, 實現更完整的機器學習應用實例。本書一開始會先介紹機器學習概念與 p5.js web editor 線上開發環境基本操作, 接著直接體驗使用 ml5.js 中的現有模型, 實作可以辨識特定物件的影像分類器。除了網頁實作神經網路外, 可再串連硬體控制板, 藉由控制板輸出預測結果, 比如使用物件偵測來判斷是否有人出現, 對應的 OLED 顯示器模組就會出現迎賓文字或相關訊息；或是語音辨識讓玩家用語音來控制遊戲, 遊戲結束後會通知控制板啟動振動馬達回饋給玩家。最後會使用 ml5 程式庫實際訓練自己的神經網路模型, 首先為利用控制板蒐集感測器資料, 再透過神經網路訓練解決迴歸問題, 如藉由溫度感測器的訊號, 找出感測值與實際溫度的關係, 做出自製即時電子溫度計, 再結合可以即時顯示畫面去背效果的 U-Net 模型, 就可以使用環境溫度來改變虛擬背景特效。接著為解決分類問題的神經網路, 使用現成的 Facemesh 模型找出臉部特徵點, 分別蒐集臉部不同的角度資料進行訓練, 最終得到一個可以辨識是否打瞌睡的模型, 再串接實體蜂鳴器在打瞌睡時, 發出警報聲提醒使用者。最後訓練的神經網路為卷積神經網路, 透過蒐集配戴口罩與否的不同照片作為訓練資料, 經過卷積神經網路訓練後, 就可以用此模型來判斷畫面中的人是否有正確配戴口罩, 再結合模擬門鎖的伺服馬達, 建構出一套口罩門禁系統的概念。本產品除實驗手冊外，實驗過程中有任何問題或是建議都可以在 Facebook 粉絲專頁《旗標創客‧自造者工作坊》中留言，即有專人為您服務。本產品 Windows / Mac 皆適用　操作本產品需要視訊鏡頭及麥克風 (筆電
