webOS SDK開放下載

還在癡癡等著何時能夠通過webOS SDK的申請時，沒想到昨天已經開放給所有人申請後直接下載囉...而回復之前SDK申請的信函則是稍嫌沒誠意的到今天才收到。

要開始安裝SDK之前要先安裝以下軟體：

• Java
  
• Safari 4
• VirtualBox

環境準備好之後可以開始安裝SDK囉

1. 首先當然要先準備好webOS SDK [1][2]
2. 接著先確定VirtualBox沒在跑，然後開始執行SDK安裝程式
3. 執行模擬器：開始 -> 程式集 -> Palm ->SDK -> Palm Emulator 或者 透過Palm webOS SDK的目錄裡面的捷徑
4. VirtualBox跑起來之後會跳出兩個對話框提醒滑鼠跟鍵盤整合情況，我是直接按掉進入模擬器畫面 XD
   
5. 接著開始把玩模擬器 (溫馨小提示：Home跟End鍵可以解決很多操控上的問題，Esc和Tab鍵也不錯)
   

到此已可先體驗一下Palm的介面與操控感覺。下一篇再來講如何開始開發程式。

初探Palm webOS

今天在癮科技上逛了一下, 看到webOS的SDK釋出了, 目前還是申請制, 在申請的同時也順便再多了解一下webOS.

Palm webOS Book from O'Reilly Media [1]

webOS integrates the power of a window-based operating system with the simplicity of a browser. Applications are built using standard web technologies and languages, but have access to device-based services and data.

You can think of webOS applications as native applications, but built from the same standard HTML, CSS and JavaScript that you'd use to develop web applications. Palm has extended the standard web development environment through a JavaScript framework that gives standardized UI widgets, and access to selected device hardware and services.

You will build WebOS applications with common web development tools following typical design and implementation practices for Ajax applications. But your webOS applications are installed and run directly on the device, just as you are used to doing with native applications.

還蠻有趣的開發方式, 開發者要使用web開發工具(HTML/CSS/JavaScript)來開發要安裝才能使用的application, 且可以存取裝置上的服務與資訊.

怎麼辦到的呢? Palm說: 謎底就是Mojo Application Framework. 這個有空再介紹~ 總之不是魔獸世界裡面打食人妖會掉的魔精就是 XD
