xPad 0.1 released!

What if Chrome OS Tablet concept UI get implemented?

Don't you love the Chrome OS Tablet concept UI above? I fell in love as soon as I read about it on the wiki, but Eric Schmidt crush my dream by stating that "Chrome OS aimed at keyboard based solutions".

I don't know either the actual roadmap of Chrome OS nor what Google has in mind, but since it's an open source project and I'm a FOSS developer, I decided to build it on my own. After a weekend of hacking, let me introduce to you:

the xPad - tablet edition of xPUD

Download: xpad-0.1.iso (47MB)

Due to the limitation of hardware support in this image, it can only boot on Virtualbox. But we have already integrated this touch and virtual keyboard solution onto MeeGo Netbook UX, and ported to some selected platforms like OMAP3 and Moorestown. (Any demo or customization request please feel free to send me a mail ;-)

Main Features

finger scrolling browser - it's basically a simple GtkWebKit browser with a custom GtkScrolledWindow widget from the Midori project. We also wrote a QtWebKit version in case you want to demo it on MeeGo.
enhanced WebKit - that rendering fast and with less library dependencies, we also patched WebCore/HTMLInputElement to hint input method with different input type, including password field.
auto showing/hiding of input method - by patching against scim-bridge, we made the Gtk and Qt4 immodule brings up the keyboard while focus in, and hide it when focus out.
virtual keyboard that can actually use - we add Toggle feature into fvkbd, that can toggle input method as well as switch keyboard layout; also applied the MODE_STATUS_TEMP patch from sayamindu to support CKJ users.
input method panel - we fixed the ToggleVkb feature of scim-panel-vkb-gtk, also adjust the layout to integrate SCIM and different input methods well.
multi-lingua keyboard layout - we carefully crafted a "bopomofo" friendly keyboard layout, that shows how flexible the fvkbd can be.

Known Issues

Apparently it's still buggy and unstable, the browser doesn't have much features like Tap-and-Hold or right click, nor tab or hiding scroll bar support, sometimes you have to toggle the keyboard and change input method to English to get it right.

But we'll keep working on that, maybe replaced it with a custom build of chromium, or some Qt-based browser like IXS-Browser from Movial.

While xPUD team are busy working on the next generation of TableWare UI, this is something you can play with during the Christmas holiday! :-)

All the best,
penk

xPUD 0.9.5 - Re-implemented everything, again

Download: xpud-0.9.5.iso (65MB)

Notice

This is a technical preview release, which only suits developers. If you're looking for next stable release please follow us on twitter.

New Features

Ubuntu 10.10 base and Linux kernel 2.6.35.7, alone with an updated build system.

TableWare platform

Starting with this version we launch a new project called TableWare, a web-based window manager, which replaced the old XPCOM/MozPlugger implementation with following software components:

new NPAPI plugin
new XCB-based window manager
Node.js and WebSocket support
new daemon with inotify and D-Bus support
new WebKit-based runtime

So the fun starts here!

How cool will it be if you can write a window manager using CSS/HTML and JS in 297 lines of code?

Known Issues

only tested in virtualbox
still very very buggy
iframe-shim doesn't work in webkit

What to expect next?

re-designed plate UI
compositor of tableware platform
ARM port and xPad, THE tablet edition! :-)
If you've got any question or request, feel free to drop me a mail

2010年11月2日星期二

xPUD 0.9.5 - 宇宙最美麗的 OS 出世了!

世上最不穩定的 xPUD 終於姍姍來遲了!

下載: xpud-0.9.5.iso (65MB)

作者的忠告

這是開發中的版本, 只適合想自己寫程式或修理錯誤的開發者使用, 若要等穩定版釋出請追蹤 xpudos 的推特帳號.

新功能

升級到 Ubuntu 10.10 系統與 Linux 核心 2.6.35.7, mkxpud 也同步更新.

TableWare 平台

自 0.9.5 開始我們正式啟動 TableWare 計畫, 它將取代 XPCOM/MozPlugger 成為下一代 xPUD 的主力平台, 新元件如下:

新的 NPAPI 外掛
新的 XCB 視窗管理員
Node.js 和 WebSocket 支援
可用 D-Bus 和遙控器操作
新的 WebKit 核心

用新平台寫視窗管理有多酷呢? 請見「輕滑頓幻舞 (Sliding Effect)」展示影片:

一共只用了 297 行 HTML/CSS/JS!

已知問題

只在 virtualbox 測試過
非常多 bug, 常常掉東西
沒有中文輸入法
iframe-shim 壞了

下集節目預告

全新打造的 plate UI
圖形加速功能
ARM 版本以及 xPad, 平板電腦介面! :-)
有任何問題或需求歡迎和我聯絡

Next-Gen xPUD

I'm planning next generation of xPUD while preparing the talk for Gnome Asia Summit this year.
Here's the fact:

we're using mozplugger and <embed> to get applications embedded for now
but we can't handle popup window, quit from applications or
application started by xterm
we need a way to listen CreateNotify / DestroyNotify event
and only window manager can do that!

Here's my plan:

write a window manager using xcb, do nothing but a) open web browser in fullscreen, and b) send dbus signal through dbus-javascript bridge to the browser while getting MapRequest event
when the browser get that signal, add an <embed> tag with an id of the window id, and reparent it
while the window manager get DestroyNotify event, remove that
corresponding <embed> tag

So we can solve this once and for all!

I've done about 50% of the window manager (haven't named it yet, any idea?), and 80% of the "touchweb" browser (based on webkit and javascript dbus bridge), we might eventually need our own NPAPI plugger (could be a stripped down version of mozplugger)

That's for now. Stay tuned.

Notes on Chromium OS for ARM

各位新年快樂! ULLab 的團隊成員除了在年假中加緊趕工, 為 xPUD 新版本加入平板模式 (tablet mode) 的支援外, 也「嘴巴說不要、身體卻很誠實」地接了一些 Chrome OS 的客製化案子.

如同之前提到的, 第一版的 Chrome OS 建置方式著實有點虛弱, 無法滿足不同平台或是未來實做各項功能的需求, 因此我們可以發現 Google 動作很快的提出了一些改進, 改用了一套新的 build system, 主要有兩個特點:

採用 Gentoo Linux 的 portage 作為套件管理/編譯系統
目前只支援 64 位元的平台

我們比較關注的 ebuild 目前都放在 ~/trunk/src/third_party/chromiumos-overlay/chromeos-base/ 底下, 若是熟悉 Gentoo 的話照著文件也可以輕易上手.

寫給自己的一些骯髒溫馨小提示:

為了略過一些套件或修正編譯問題, 改完 ebuild 以後要重新產生 Manifest, 如 ebuild ~/trunk/src/third_party/chromiumos-overlay/chromeos-base/chromeos-chrome-bin/chromeos-chrome-bin-0.0.1-r1.ebuild manifest
若有自己重打包原始碼放在 /var/lib/portage/distfiles/, 要重算 du -b, rmd160 -x, sha1sum 和 sha256sum. (太髒了不推薦 XD)

另外有別於一般的 chromium 瀏覽器, 我們需要的是 "chromeos" 版的 (這樣才有左上角的 Panel), 在取得原始碼後:

於 .gclient 中加入:

{ "name"        : "cros_deps",
   "url"         : "http://src.chromium.org/svn/trunk/cros_deps",
 } ,

設定 GYP_DEFINES=chromeos=1

xPUD 火力展示：全世界最小的 Chromium OS

下載: minimized-chromiumos.iso (58MB)

xPUD 專案的特色一向是強調活動規劃式 (activity-based) 的介面、對既有程式與網頁的整合、以及降低網頁開發者撰寫客製化介面的門檻。很高興 Google 的 Chrome OS 專案與 xPUD 團隊對於未來的作業系統分享著一些共通的觀點，儘管我們說著不同的故事，但有著相似的看法。

在測試過 Chromium OS 及其編譯系統後，我們發現這是一個絕佳的機會，可以藉此展示 xPUD 的彈性與縮小體積的能力。因此我們很高興的釋出此一實驗性質的版本：Minimized Chromium OS。相較於一般動輒 2G~4G 的映像檔，xPUD 的編譯系統 mkxpud 成功地將整個系統體積縮小為不到 60MB。

注意：這個版本並不適用於一般使用者的日常使用，更多資訊請參考以下關於技術細節的段落。

安裝方式

就像每一個 xPUD 檔案一樣，這個 ISO 本身是 LiveCD 也是可開機的混合式映像檔 (hybrid iso image)。因此製作可開機隨身碟的方式非常簡單，直接使用 dd 指令即可：

# dd bs=4096 if=minimized-chromiumos.iso of=/dev/sdX

主要功能

縮小的系統：基本系統 (32MB)；瀏覽器 (18MB)；輸入法 (8MB)
跳過開機畫面與登入選單
Chromium OS 瀏覽器與外掛 (不包含 DeviceKit 所以電量顯示沒有作用)
中文字型與常見輸入法

技術細節

其實根據官方的文件顯示，第一階段的 Chromium OS 實作真的沒有什麼特別，說穿了不過就是個 Ubuntu 系統加上瀏覽器，以及用 Clutter 寫成的視窗管理程式。

開機流程當中，以樹狀圖來看就是

slim
|-- Xorg
`-- ck-launch-session
          `-- chromeos-wm -+-chromeos-chrome

由 /sbin/chromeos-startup 這隻程式叫出開機畫面，透過 SLiM 進行登入管理，在使用者登入後，執行 /etc/X11/chromeos-xsession 開啟視窗管理程式 /usr/bin/chromeos-wm，並透過無限迴圈的 /usr/bin/chromeos-chrome-loop 確保瀏覽器不會被關掉。

這是一個在接案子的過程中產生的有趣實驗，我們的用意是以此來探討 Chromium OS 的客製化與開機流程，也歡迎有興趣加入參與 xPUD 開發的人敬請指教。 :-)
