一堆國外新聞網站超愛這套,這不是 Flash 時代的搞法嗎,怎麼現在還這樣搞啊... 在 Google Chrome 內建的設定就可以關掉了,先進入 chrome://flags,然後選擇「Document activation is required.」:

中文版的 Chrome 不知道是翻成什麼,就自己翻譯猜一下吧...

Amazon CloudWatch 支援縮放與拖拉調整時間區間

Amazon CloudWatch 的操作上支援 Zoom 與 Pan 了:「Amazon CloudWatch now supports two new chart visualization options in metrics and dashboards」。

Zoom 是改變時間的粒度:

You can use the CloudWatch console to graph metric data generated by AWS services and your applications. Now, you can zoom into a shorter time period such as one minute or five minutes while viewing the metric graph at a longer interval.

Pan 則是維持一樣的粒度,但改變開始與結束的時間:

Once zoomed, you can also pan the metric graph across your selected interval, but at a zoomed detail level.


iOS 11 的無線網路與藍芽關假的讓 EFF 不爽...

這次 iOS 11 的無線網路與藍芽需要到 Settings (設定) 裡面才能有效關掉的設計,讓 EFF 不爽寫了一篇文章:「iOS 11’s Misleading “Off-ish” Setting for Bluetooth and Wi-Fi is Bad for User Security」。

On an iPhone, users might instinctively swipe up to open Control Center and toggle Wi-Fi and Bluetooth off from the quick settings. Each icon switches from blue to gray, leading a user to reasonably believe they have been turned off—in other words, fully disabled. In iOS 10, that was true. However, in iOS 11, the same setting change no longer actually turns Wi-Fi or Bluetooth “off.”

不過藍芽的洞真的不少,儘量避免吧... +_+

Flat UI 反而造成使用者困擾

在「Flat UI Elements Attract Less Attention and Cause Uncertainty」這邊透過追蹤眼球的技術,發表了研究結果:

Summary: Flat interfaces often use weak signifiers. In an eyetracking experiment comparing different kinds of clickability clues, UIs with weak signifiers required more user effort than strong ones.

其中最明顯的一個例子就是大家被訓練「有底線的文字應該可以按」,這也是最能馬上被想到的問題... 不過這算是 Flat UI 的問題嗎?

The popularity of flat design in digital interfaces has coincided with a scarcity of signifiers. Many modern UIs have ripped out the perceptible cues that users rely on to understand what is clickable.

Jenkins 的 Blue Ocean 計畫,改善使用者操作的友善度...

JenkinsBlue Ocean 計畫打算改善讓人頭痛很久的操作體驗了:

Blue Ocean is a new project that rethinks the user experience of Jenkins.

Jenkins 讓人頭痛有兩個面向,一個是界面很難讀,另外一個是操作流程很沒有規則,所謂「熟悉 Jenkins」其中一個很艱難的任務就是要背下一堆功能「蔵在哪邊」。而這次 Blue Ocean 想改善的事情看起來主力放在界面,對於流程修的比較少... 即使如此,這還是可以讓使用的人減少一些痛苦就是了...


在專案頁面的後面有提到 Blue Ocean 用的技術:

Blue Ocean is built as a collection of Jenkins plugins itself. There is one key difference, however. It provides both its own endpoint for http requests and delivers up html/javascript via a different path, without the existing Jenkins UI markup/scripts. React.js and ES6 are used to deliver the javascript components of Blue Ocean. Inspired by this excellent open source project (react-plugins) an <ExtensionPoint>pattern was established, that allows extensions to come from any Jenkins plugin (only with Javascript) and should they fail to load, have failures isolated.

又是個不需要用 SPA 呈現的東西跑去用 React 了...

Google Chrome 停用平滑捲動

因為把 JavaScript 開回來了,所以有這個困擾... :(

Google Chrome 的平滑捲動可以透過 chrome://flags 裡面的設定關閉 (OS X 上則是透過系統設定關閉),但就是有不少網站會很雞婆,用 JavaScript 模擬平滑捲動,所以就花了時間把 extension 寫出來:「Stop Smooth Scrolling」。

由於大多數平滑捲動的作法都是透過對 document 或是 window 上掛上與平滑捲動相關事件做到的,所以我是透過 addEventListener()useCapture flags,然後再用 preventDefault() 擋下後續的處理。

這樣做會有一些問題,其中比較明顯的是地圖類功能的滾輪會失效,這個部分我先放進預設的白名單了,如果有其他的問題,除了可以自己加以外,也可以開 ticket 讓我加進預設清單 :o
