ios 快說SwiftUI對iOS開發者影響 Apple 在這介WWDC對Cocoa Cocoa Touch 的Developer按了一次Reset，最起碼UI層面上。不少身邊友人看了簡介，立即中年危機上身，開始吐糟門檻又變低了一大半啊，新人湧現啊，存在感決失啊如此這般。但是真的便是這樣嗎？其實同時是，亦都不是。首先，對於開了簡介便下此判斷的人，我想說聲對不起，對你來說，可能真便如此。或許那麼簡單便下判斷，便是你那中年危機的成因。你需要的，不是讓Apple收回成命，而是重新審視這些年來，自己學會了什麼。不是說你一定便不求上進，只是可能在軟件開發的領域裡，你嚴重偏科了。讓我們認真聊聊吧。軟件領域，是進化得最快的一個行業。就算只談UI，在SwiftUI出現之前，

programming 關於開四停三的「大」數據迷思 新年回廣州探親，在親友車上，聽其誇耀現在廣州市的數據處理能力及規模的厲害。cctv滿街，最少一星期的視頻數據才能支撐得起那開四停三的厲政，這般那般。當然了，我對中國挖掘個人數據的能力，是不會致疑的。要說當今世界對圖像的深度學習領域，中國必為前列。而其背後的主要推動，當然是監控的需求。在這番共聚天輪的家庭閒聊之中，最叫我好奇的，是從技術角度能出發及解釋得了的一個問號 - 開四停三的數據規範。首先，視頻數據是不會直接入庫的。視頻可以儲存，數據可以接某視頻或其分段，但沒有表是直接一個BLOB把視頻放進去的（嗯⋯⋯是沒有的🙈）。想當然，分析也不會直接依賴原始數據，特別是視頻數據。數據入庫在視頻數據分析前，首先是feature extraction，這裡可以走過不少的pre processing

culture 開發者該如何學習的角度看別人產品 作為一個開放者，我們該怎樣去看別人的產品？ 要答這一個問題，便只能從所有軟件產品的根源說起⋯⋯ 電腦程式的本質，便是對電子活動的一層一層抽象。我們從電流的開合，數學的模擬，語言的整合，直到圖形系統，無一不是在更高的位面對低位面的一次抽象。 但即使是每天都進行著抽象活動的我們，也未必會時刻保持抽象的角度看待別人的產品。因為我們太習慣於具象的世界了。 上一次我看見的開發者集體跳崖事件，便是material design出現時。 抽象是一層一層地向上的，我們繼續談Material Design。 遊戲開始，請簡短說出什麼是Material Design。 3 2 1 ⋯⋯ 好了，對於你來說什麼是Material Design呢？ 是卡片、圓角？陰影、過渡？
