透過演算法修照片的工具
看到「A simple interface for editing natural photos with generative neural networks.」這個工具，直接看這個兩分鐘的影片比較清楚知道他想要做的事情： 當你修正了某一個點後，這個工具就透過演算法改變其他的點，讓照片看起來變得自然... 作者所發表的論文可以在「Neural Photo Editing with Introspective Adversarial Networks」這邊下載到。

關於 Sully (薩利機長：哈德遜奇蹟) 的資料
《薩利機長：哈德遜奇蹟》講的是「全美航空1549號班機事故」，有不少資料可以先看過再去看電影。(這部片要整個劇透透光後，去電影院刷個兩次會特別有感覺) 特別推薦看 IMAX 版，螢幕大感覺就是不一樣... 另外結尾的彩蛋有兩則，請不要看完第一則就跑掉了。(話說回來，上上星期五去長春國賓看的時候居然沒看到第二則就被工作人員告知已經結束，不知道是怎麼一回事...) 首先是維基百科的資料 (當作入口點)： 全美航空1549號班機事故 US Airways Flight 1549 中文版會容易看一些，不過英文版的資料比較豐富。 另外維基百科上面也有人從 FAA 所公開的資料中截出 New York TRACON 的錄音抓出對應的部份，並且將對話過程抄寫出來：「File:Flight 1549 FAA New York TRACON audio extract.ogg」，電影的確照實將這些對話演出來： 在「Flight 1549 3D Reconstruction, Hudson River Ditching Jan 15, 2009」這邊依照公開的錄音 (從在機場起飛開始) 以及所有公開的對話記錄 (黑盒子的記錄)，配上模擬機上的畫面，也可以看一看： … Continue reading
不打開書直接掃描內容
MIT Media Lab 弄出個好玩的東西，可以不打開書直接掃描書的內容：「Can computers read through a book page by page without opening it?」，主標題是「Terahertz time-gated spectral imaging for content extraction through layered structures」。 用 100Ghz 到 3Thz 的電磁波掃描： In our new study we explore a range of frequencies from … Continue reading
Firefox 51 (現在是 48) 將會支援 FLAC
在 Hacker News Daily 上看到 Firefox 要支援無損格式 FLAC 的消息：「Bug 1195723 - FLAC support / Create FLAC MediaDataDemuxer」。 隔壁棚關於 Google Chrome 也有 FLAC 相關的「Support FLAC audio codec」，也是等很久都沒消息，不知道會不會因為 Firefox 有進度後... 現在如果要無損的話只有 WAV 可以用 (話雖如此，IE 還是要到 Edge 才有支援)，改用 FLAC 大約可以省下 40% 的大小 (平均值，依照音樂的類型會有不一樣的壓縮率)，如果普及的話，不知道 … Continue reading
在遊戲上模擬跑步的動作
從「Balls to learning how to animate, let's film some parkour!」這篇看到讓人懷念的遊戲，1989 年的《波斯王子》： Jordan Mechner (波斯王子的作者) 用 Rotoscoping 的方式將他弟弟做這些動作的畫面拍下來，然後確保在電腦上角色的動作是順暢的： Here's the source frames used to rotoscope the above animation. Don't let the ghostly pallor fool you! Jordan Mechner's brother is in fact … Continue reading

電子書在美國的販售管道與作者的獲利
在美國，五大出版商在電子書拆分上對作者佔的比例不斷的下滑，這也代表話語權不斷的下降，而且愈來愈不需要這些「大」出版商了：「Independent authors are starting to outsell the Big Five」。 這邊所提到的 Big Five 可以在「The Big Five Trade Book Publishers」這邊查到，分別是： Hachette Book Group HarperCollins Macmillan Publishers Penguin Random House Simon and Schuster 另外也可以把 Amazon 當作是電子書產業的大公司。可以看到獨立發行的比率愈來愈高： AuthorEarnings.com has published a report on this … Continue reading

Apple 的 App Store 的訂閱制度更新
先前在「蘋果 App Store 收費模式的改變」這邊提到的改變，這幾天細節公開了：「Subscriptions - App Store - Apple Developer」。 最主要的改變在於超過一年的費用從原來的 30% 降低到 15%： Within a subscriber’s first year of an auto-renewable subscription, you receive the traditional 70% of the subscription price at each billing cycle, minus applicable taxes. After … Continue reading

美國人的閱讀習慣 (以閱讀的媒介來分)
在「Book Reading 2016」這邊看到一張圖表： 閱讀人口並沒有太明顯的變化 (以 2012 之後來看)。所以解釋成習慣讀紙本的還是很喜歡紙本的感覺，但是電子書的接受度愈來愈高？ 另外一張圖表則把受訪者的 profile 拿出來細分，性別、種族、年齡、教育程度、年收入、所在地區： 有不少有趣的數字，解讀看個人了 :o

玩 Pokémon Go 抓怪用的 iPhone 手機殼...
看到「This iPhone thong case will help you catch 'em all in 'Pokémon Go'」這個，光看圖就知道意思了： 應該是用 3D Printer 做出來的： If this sounds familiar, it's basically the commercialized, rubberized version of the 3D-printed Poké Ball "aimer" case that one guy made. 不過這不能丟 Curveball … Continue reading
Star Trek 五十週年郵票
美國郵局決定要發行 Star Trek 五十週年郵票：「Star Trek Postage Stamps Coming Soon: Celebrating 50 Years of Exploring the Final Frontier」。 也快五十年了啊： The original Star Trek TV series took to the airwaves nearly 5o years ago–on September 8, 1966.
