study note for my first Perl program

2011-11-16T17:38:00.001+08:00

Because of project maintenance requirement, it's better exist some scripts to deploy project form git-server and automate regular regression test. Our project source tree isn't too simple and there is too much branch on works concurrent. Thus meaning I can't use a simple bash script to deploy the project environment.

Consider all the requirement,I decide write those scripts in Perl. It's my first time Perl Programming, this article collects some little tips or code for reference.

basic tips & sample code

Reading Keyboard input
Remember using chomp() to cleanup "CR"

#!/usr/bin/perl  
$line = <>;  
if($line eq "\n") {  
        print "Only empty line!\n";  
} else {  
        print "Input: " . $line . "\n";  
}

schema tag for blogging

2011-11-10T13:53:00.001+08:00

因緣下發現 schema.org 這語義標籤。

schema.org, microdata, microformat, RDFs... 等標準都有著相同的目標，將網頁資料格式化，讓搜尋引擎可以更能精確的判別每筆資料所代表的意義。如此，網路世界才能更相通，資料交換更加容易。甚者，可以發展特別的 extension 來瀏覽某些特定資訊。

原本是要細追 microformat 的使用，卻發覺 microformat 的發展不如預期，而 google, yahoo, bing... 等都提出對 schema.org 的支援。很認同語意標籤的觀念跟作法，既然要改，就以最新標準來修改吧！

打算將部落格特定主題文章全面改用 schema.org 的相對應標籤來改寫，並設計獨立的 CSS 以嵌入到各個部落格，初步的嘗試是 let-lohas 的店家資訊。

參考 schema.org/Restaurant 的規範，初步寫了個簡單的店家資訊跟樣式表，還有許多要調整的欄位跟顯示樣式，留待哪天想到時再調整吧：

套用在 lets-lohas 的範例在此

寫樣式的時候發覺許多之前收集的 bookmark 其實派不上用場，倒是 google 到了許多好用的工具網站。
看來該找時間重新整理 bookmark 了。

Using git to manage dotfiles

2011-10-22T12:22:00.000+08:00

After saw the article 使用 Git 管理自己的 dotfiles. I want to put my dotfiles into a git repository and write some deploy script to setup new Linux environment. Finally, the work is done during some modification.

I use three branch for my dotfiles:

public: Basic setting. It includes bashrc, vimrc, deploy scripts, ...etc. I push this branch to github public project for publish to blog. Any comment is welcome to improve my script & rcfile.
.
private: Some personal information unsuited to publish, like github access key, netrc for git access and so on. I push this branch to bitbucket private repository for sync between my machines.
This private branch always rebase public after any changes.
.
local: The setting for which machine only. $PATH, specially software config, ...etc
Like private, the local branch always rebase private.
.

I also write a script to sync local and hosted repository as followed.

Again, Any comment is welcome.

fix Android building error on ubuntu 11.10

2011-10-20T15:16:00.000+08:00

系統升級 ubuntu 11.10 過程相當順利，瀏覽器資料也多虧 sync 的功能一下子就回復，雲端的時代來了(笑)。
升級後編譯 Android 出現錯誤，仔細比對後因為 gcc/glibc 的版本不同所造成，許多問題 google 真的可以找到解法省下不少時間，不過也要慢慢累積經驗，可以看到問題直覺反應如何解決！
先把遇到的問題跟解法一點一滴記錄下來吧。

Xubuntu 11.10 Oneiric Ocelot AMD64
gcc version 4.6.1 (Ubuntu/Linaro 4.6.1-9ubuntu3) (system default)
Android 2.2.1 (MDK3D BSP)

compile the Android 2.3 with your installed GCC 4.6, you will receive the following error message:

To fix that, open a terminal and run (assuming you are in the folder android):
```

不使用密碼的SSH連線 - ssh-keygen

2011-09-26T10:31:00.000+08:00

ref: http://slv922.pixnet.net/blog/post/26419814

A電腦 192.168.1.1- 要被連線的主機
B電腦 192.168.1.2- 使用SSH連線到A電腦的主機

小明在 A主機有一個使用者帳號 A_min
在 B主機有一個使用者帳號 B_min

環境設定 - A主機
# vi /etc/ssh/sshd_config RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile .ssh/authorized_keys PasswordAuthentication no （如果不想讓使用者使用密碼登入的話再設定） # service sshd restart
.
步驟一 - 於B電腦使用ssh-keygen 產生兩把金鑰
B電腦
[B_min@B電腦 ~] $ ssh-keygen -t rsa
(按三下Enter 不用設密碼)
會在 /home/B_min/.ssh/ 目錄下產生2個檔案: id_rsa , id_rsa.pub
.
步驟二 - 將 B電腦產生的 id_rsa.pub 上傳到 A電腦的 A_min家目錄底下 (什麼方法都可以只要你把它放進去就對了)
[B_min@B電腦 ~]$ cd ~/.ssh [B_min@B電腦 .ssh]$ scp id_rsa.pub A_min@192.168.1.1:~/

關鍵的步驟三：接下來要在A主機上操作了,用SSH連線或是直接在A主機上操作,隨意!

A主機
[A_min@A電腦 ~]$ cd ~/.ssh [A_min@A電腦 .ssh]$ cat ../id_rsa.pub >> authorized_keys [A_min@A電腦 .ssh]$ chmod 644 ~/.ssh/authorized_keys
.
驗證
[B_min@B電腦 ~]$ ssh A_min@192.168.1.1 Last login: Fri Feb 27 21:40:00 2009 from 192.168.1.2
.

恭喜你不用密碼登入囉

Windows Client - B電腦是Windows Client的話...

需要工具軟體：PuTTY , PuTTYgen　下載

金鑰產生方法
使用PuTTYgen產生金鑰


Generate > 滑鼠亂動進度列跑跑跑(很有趣XD) > 金鑰演算完成

Save Public Key > 存檔 → 步驟一的 id_rsa.pub
Save Private Key > 存檔 →  步驟一的 id_rsa

阿接下來就跟步驟二之後一樣，把id_rsa.pub丟到A電腦上的A_min帳號....自己看著辦

PuTTY使用金鑰連線方法

很簡單只要設定一個地方
設定畫面 > Connection > SSH > Auth
將key的位置放入Private key file for authentication
填好連線主機IP就Open吧


login as:A_min
Authenticating with public key "imported-openssh-key"

用誰登入就看你把id_rsa.pub丟到誰家
因為我們範例裡面丟到A_min家，當然是用A_min的帳號來連線

Android.mk 筆記

origin: Android.mk 筆記

---

不建議將 Linux kernel driver 直接放入 Android source tree.
Android building system 與 Linux kernel source 兩者使用的 Building system 行為與 config/ c flag 並不相同.
所以多習慣預先編譯 .ko 檔, 然後在 products.mk 中寫明 PRODUCT_COPY_FILES

Android building system 簡單介紹

重點在於 LOCAL_MODULES 跟 LOCAL_SHARE_MODULES 這兩個參數去建構出所有需使用到的 modules
所以的 runtime library 的 LOCAL_NAME 一定要被上層 MODULES 所使用

(Jollen 所提供的 mokoid/hardware/modules/led 範例, 較簡單易懂)

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)

# our own branch needs these headers
LOCAL_C_INCLUDES += \
vendor/mokoid/hardware/modules/include/
    編譯此 project 時所使用的 include 檔位置
    Android build system 會指名自己的 includes files path, 而各個 project 可自行指名所使用的 include path
    #include "a.h" 
    編譯系統會到 LOCAL_C_INCLUDES 找這個 header file.

LOCAL_PRELINK_MODULE := false
LOCAL_MODULE_PATH := $(TARGET_OUT_SHARED_LIBRARIES)/hw
LOCAL_SHARED_LIBRARIES := liblog
    編譯本 modules 所需使用的其他 modules
    Android build system 會以所有 Android.mk 中的 LOCAL_MODULE 的名字命名.
    並依該 modules 所使用的 SHARED_LIBRARIES 去建立 building tree
    以這個例子來說, 要編 led.goldfish 需先編譯 liblog 這個 modules

LOCAL_SRC_FILES := led.c
    本 modules 的 c code

LOCAL_MODULE := led.goldfish
#LOCAL_MODULE := led.dma6410xp
    上述的此 modules name

include $(BUILD_SHARED_LIBRARY)

(0xdroid/hardware/alsa_sound/Android.mk, 多了一些環境變數的檢查, 比較完整也較複雜, 基本行為一樣)

# hardware/libaudio-alsa/Android.mk
# Copyright 2008 Wind River Systems
#

ifeq ($(strip $(BOARD_USES_ALSA_AUDIO)),true)
 LOCAL_PATH := $(call my-dir)

 include $(CLEAR_VARS)

 LOCAL_ARM_MODE := arm
 LOCAL_CFLAGS := -D_POSIX_SOURCE

 LOCAL_WHOLE_STATIC_LIBRARIES := libasound

 ifneq ($(ALSA_DEFAULT_SAMPLE_RATE),)
   LOCAL_CFLAGS += -DALSA_DEFAULT_SAMPLE_RATE=$(ALSA_DEFAULT_SAMPLE_RATE)
 endif
 ifeq ($(strip $(BOARD_HAVE_FM_ROUTING)),true)
   LOCAL_CFLAGS += -DFM_ROUTE_SUPPORT
 endif

 LOCAL_C_INCLUDES += external/alsa-lib/include

 LOCAL_SRC_FILES := AudioHardwareALSA.cpp

 LOCAL_MODULE := libaudio

 LOCAL_STATIC_LIBRARIES += libaudiointerface

 LOCAL_SHARED_LIBRARIES := \
   libcutils \
   libutils \
   libmedia \
   libhardware \
   libhardware_legacy \
   libdl \
   libc

 include $(BUILD_SHARED_LIBRARY)
 include $(CLEAR_VARS)
 LOCAL_PRELINK_MODULE := false
 LOCAL_MODULE_PATH := $(TARGET_OUT_SHARED_LIBRARIES)/hw
 LOCAL_CFLAGS := -D_POSIX_SOURCE -Wno-multichar
    給 gcc 用的 flag, 這部份詳細下法必須參考 gcc manual
    這跟 pkg-config 沒有關係

 LOCAL_C_INCLUDES += external/alsa-lib/include
 LOCAL_SRC_FILES:= acoustics_default.cpp
 LOCAL_SHARED_LIBRARIES := liblog
 LOCAL_MODULE:= acoustics.default
 include $(BUILD_SHARED_LIBRARY)
endif

Android 3.0 GPUI (hardware accelerated UI)

2011-09-09T15:57:00.000+08:00

Android 並沒有 Windowing 的架構，Application 建立 Surface 後進行繪圖與顯示。Andorid 中繪圖有幾種方式：Canvas - 2D drawing context, Skia – 2D drawing API, OpenGL – 3D rendering API 以及 Android 2.2 之後開始支援的 OpenGL|ES 2.0 規格，開發者可使用 RenderScript (Language + API) 繪製3D圖型。

為確保 Application 能正常在各個 Android 平台上執行，Android 實作了軟體 OpenGL|ES API - libAGL.so。若裝置上並沒有 GPU 的話，則以軟體來處理 3D graphic；而若 Android 裝置有 GPU，則由 GPU 所提供的 libHGL_cyclone.so 把 3D 圖形轉交給 GPU 去運算，效能會好許多。

Application 可以使用 Canvas 透過 skia library 繪製、直接使用 OpenGL|ES 1.x fixed API 來繪製 3D graphic，或使用 OpenGL|ES 2.0 的 RenderScript，開發者得選用相對應的 Surface 去繪圖。

Android 3.0 重寫了常用的 2D UI compoment 繪製方式，特點是借用 GPU 對圖形處理能力來加快效能，稱為 UI on the GPU，簡稱 GPUI。GPUI 基本運作概念是將每個 2D UI component 轉換成兩個三角形的物件去貼圖，這部份的觀念跟先前 Android 處理 LayerBuffer 的作法一樣。而藉由GPU的處理，在shading、alpha blanding...等運算上，速度會比原本使用 Cavans + skia + pixelfligner 快許多。

對開發者而言，Android GPUI 提供多種不同層級 hardware acceleration 設定，可分別針對 Applicaion、Activity、Window、View 去設定是否使用 hardware acceleration。若程式中僅使用標準 drawable 元件例如list、button、path...等標準 2D UI component，程式開發員可以打開 Hardware acceleration 功能，以使用GPU 繪製。開發者也可以利用 View.isHardwareAccelerated() / Canvas.isHardwareAccelerated() 來得知所運行的平台是否支援 GPU 硬體加速，用以選擇所使用的 UI component，達最佳顯示效果。

在 Android 發展中，愈來愈多 application 使用 3D graphic 去做 UI 特效處理，而 Android 本身亦利用 GPU 的特性對於 2D UI component 做最佳化，GPU 在 Android 上扮演愈來愈重要的角色。

compile a kernel on ubuntu way

2010-10-05T16:14:00.001+08:00

使用 Ubuntu/MacOS 一段時間了，逐漸習慣把系統管理雜事丟給 OS 去處理，專注於自己的工作開發，也比較不盲目追求 kernel 的版本更新。

近來使用 LTP 時遇到自行編譯 Ubuntu kernel 的需求，總手動編譯、複製檔案與修改 grub.cfg。猜想 Ubuntu 應該有更方便的工具用來包 kernel.deb 檔，求助 google 大神後看到 kernel-package 這個套件，以及相關的 scripts。

科技果然來自人性，重複煩雜的工作就應該丟給電腦去自動化處理。

操作大致參考 How to compile a kernel on Ubuntu 10.04

簡單紀錄如下：

install necessary packages for building kernel image

sudo apt-get install fakeroot kernel-wedge build-essential makedumpfile kernel-package libncurses5 libncurses5-dev

get kernel source tree

download from kernel.org
tar jxvf kernel-x.x.x.tar.bz2
cd kernel-x.x.x

sudo apt-get install linux-source
tar jxvf /usr/src/linux-source-x.x.x.tar.bz2
cd linux-source-x.x.x

start with the same .config ad the currently running kernel

make oldconfig
make menuconfig

cp -vi /boot/config-'uname -r' .config
make menuconfig

packing debain kernel package using kernel-package

sudo fakeroot make-kpkg clean
sudo fakeroot make-kpkg --initrd --append-to-version=-ltp kernel-image kernel-headers
--initrd create a image package suitable for initrd

install customized kernel

cd ..
sudo dpkg -i linux-image-x.x.x-ltp.deb
sudo dpkg -i linux-headers-x.x.x-ltp.deb

generate initrd to your kernel image
find the forder name to your kernel modules

ls /lib/modules
sudo update-initramfs -c -k x.x.x-ltp

add the initrdfs image to the grub.cfg

sudo update-grub

now, just reboot!
your new kernel should automatically load.

uname -r

下篇來寫寫 Linux Test Project 的簡單心得

stupid mistake/bugs

2010-08-13T05:42:00.003+08:00

近來寫程式前總在腦中先模擬完整個程式的架構、演算法以及可能的最佳化方式。
為了最佳化執行效率，macro/inline function/function pointer/... 最近也用得兇！
好處是使用得當的話，程式效率會提高不少；缺點則是在 debug 時難找出問題～

說到 debug，最近鮮少遇到程式邏輯構思錯誤的情況，大多數時間反而花在一些很愚蠢小地方的 bug。
以下列出兩條出錯的程式片段，提點自己別再犯！

if (a = NULL) {
    ...;
}

== 打成了 = ，條件判斷變成 assignment。
這已經是近來第二三次犯這種錯了，謹記！

uint32 x = 0, y = 10;
for(y; y >= x; y--) {
    ...;
}

unsigned integer 減到小於零，segmentation fault！

兩個錯誤都是耍蠢的基本錯誤，剛好犯錯的地方都是在邊界條件判斷，
要重建出錯環境不容易，為此還寫了一大段程式來測試，也算有收穫。
果然程式、專案的成熟度，取決其測試環境的成熟度！

這樣的錯平時也許不會犯，專案越趕反而越容易出搥在不該犯錯的地方，
寫篇網誌記錄一下，下次不能再犯！

mojo, an engineer's view

2010-01-13T09:02:00.006+08:00

日前跟幾位友人到東區一間餐廳用餐，對該餐廳號稱的多媒體互動餐桌很有興趣。

端詳了一下吊掛在餐桌上的裝置，看到硬體就大致上可猜出技術規格。裡面是一台 benq 投影機、acer atom nettop、紅外線 sensor。紅外線 sensor 感測用餐客人手勢後回傳訊息給電腦，運算處理後投影出來。只要訊息格式設定正確，點餐軟體並不需要特別花功夫去「客製化」。寫法跟使用滑鼠操控一模一樣，用 flash 就可以寫的出來了。

這樣的系統，我想我有能力做的出來。

進一步來看該裝置的成本，Benq 單槍投影機、atom nettop，x86 base solution，搞不好 mojo 承包廠商還是用 Windows 當作業系統呢，若玩到一半出現藍色畫面，應該很精采。

個人以為這樣的裝置，應該徹底使用 embedded system。我會選 beagle board 配上微型投影機，ARM-base embedded linux system。硬體成本約兩萬，比 x86 base 整整省了一萬多。日後的耗電量更是選用 atom nettop 的五分之一不到。

除硬體外，軟體搭配更是重點。

mojo 的互動多媒體，除了菜單、結帳外，另外就只有可以更換桌布與會亂飛的小蝴蝶。剛開始會覺得新鮮有趣，玩一下下就會膩了。已經花了那麼多預算設置這樣的裝置，只有這些功能實在太浪費。

只要 UI 好好設計，操作流程直覺，功能再複雜都不會對 user 造成困擾。

我會在桌邊設置 usb 插槽或讀卡機，軟體多寫一個秀圖的功能，讓客人可以自行插卡瀏覽相片。白天出去玩拍的相片，晚上邊用餐就可以邊看邊聊，這樣應該會比單純選擇不同桌布來得有趣。

我也會在裝置上加裝 webcam，為這樣用餐聚會留個記錄。在 youtube 申請個 mojo 帳號，客人同意後可立即將上傳影像到網路與其他好友分享。客人插上隨身碟或記憶卡後，也可把這次用餐的影片存檔。

每次聚會都是值得珍藏分享的回憶，若能利用這樣的小裝置，增進來此聚會朋友之間的情誼，對餐廳本身也是利多。以上個人意見，樂見看到本文的多媒體廠商好好發揮。期待下次用餐時，多媒體互動餐桌可以帶來不同的感受。

最後小小廣告一下，以上技術，我們小組有自信可以完成。若有興趣歡迎聯絡。

2010-01-07T10:30:00.004+08:00

smartphone 時代真的到了

最近路上、街上、咖啡廳、餐廳裡，簡單望去。一眼可分辨的手機以 iphone 佔大多數，而 android 系統手機也不少。倒是紮根已久使用 WM 系統的手機越來越少見。

iPhone 的成功模式不需贅談，android 的開放原始碼，除了吸引了許多社群、廠商的加入研發外，技術規格的成長速度也超越 iPhone，率先支援了 flash 10 的播放。

網路上最近最紅的應該就是 google nexus one 的發表吧，發音唸起來接近 next one，看來 google 有心在智慧型手機上另創標竿。而 More Prospective Buyers for Android According to Survey 的分析也清楚表示，android 系統正急起直追。

android 跟 iphone 最終會越來越相像，即使購買族群還是不同，最終可以想像的都是行動上網的新世界很快到來。

graphviz crazy testing

2009-12-10T15:40:00.012+08:00

小Q讀書會12月討論《自願被吃的豬》，內容由100則小故事組合，每篇引起一些哲學思考實驗，完整的讀書心得在此。這本書每篇故事後面都指出另外四篇相關的文章，整理心得時突發奇想，若把這樣的關係圖畫出來不知會如何？

一想到共有100 nodes，400 edges，直覺就是拿 graphviz 來產生，否則要一一畫點連線，我會瘋掉～

by using raw editing, replacement text editor tips, the dot file was be written in the short time.
http://freetexthost.com/sjcxlh4ew1

這個dot檔有幾個特性：
1. 共有 100 個 node
2. 每個 node 會指向其他四個 node, 所以共有 400 條 edge
3. 相連的 node 相關性較高。所以可能有幾個 node 彼此相連，而不和其他 node 相關連的情況

透過 graphviz 畫出來的圖如下：

好花阿～跟想像中完全不一樣。
雖然知道一些 graphviz 排版技巧，但面對這麼複雜的圖，完全沒有頭緒從何排版起。

上了 graphviz 查了一下，原來有多種不同的 layout 方式可以使用。預設是標準的 dot layout
dot - ``hierarchical'' or layered drawings of directed graphs. The layout algorithm aims edges in the same direction (top to bottom, or left to right) and then attempts to avoid edge crossings and reduce edge length.

以下是使用不同 layout 產生的圖：

neato - ``spring model'' layouts. Neato attempts to minimize a global energy function, which is equivalent to statistical multi-dimensional scaling. The solution is achieved using stress majorization, though the older Kamada-Kawai algorithm, using steepest descent, is also available. fdp implements the Fruchterman-Reingold heuristic including a multigrid solver that handles larger graphs and clustered undirected graphs.

fdp - ``spring model'' layouts similar to those of neato, but does this by reducing forces rather than working with energy. Fdp implements the Fruchterman-Reingold heuristic including a multigrid solver that handles larger graphs and clustered undirected graphs.
sfdp - multiscale version of fdp for the layout of large graphs.

twopi - radial layouts, after Graham Wills 97. The nodes are placed on concentric circles depending their distance from a given root node.

至於我心中最理想的 circo layout algorithm 則跑不出結果，可能太複雜了吧。XD
circo - circular layout, after Six and Tollis 99, Kauffman and Wiese 02. This is suitable for certain diagrams of multiple cyclic structures such as certain telecommunications networks.

由結果可見 neato, sdfp, twopi 都有中心區塊較複雜、邊緣較簡單的情況，尤其以 twopi 更明顯，關連最多的點幾乎都在中心區塊了。而本圖的『群組』特性，則是 dot, sdfp 呈現的比較清楚，相關的 node 幾乎會在附近自成一圈。

這個 special case 還挺好玩的，graphviz 要深入摸索也還有很多有趣的點子。
真佩服這樣的 open source project，總帶來許多創意跟活力。

GPU Virtualization for VDI

2009-10-27T00:17:00.004+08:00

GPU Virtualization on VMware's Hosted I/O Architecture

View more documents from guestb3fc97.

這投影片很清楚的表達了 VMware 對於 GPU virtualization 的作法，以及一些加速及改進空間。而在 VMware SVGA Device Developer Kit 所下載的 src tarball 中也可看到 VMware SVGA Device Emulation 所預留的 Device Programming Interface。GPU Virtualization on VMware's Hosted I/O Architecture 這篇 paper 中所介紹的，主要是針對 Type2 Hypervisor(Hosted VM) 的 GPU acceleration。

而 VirtualGL 所著重的則是 thin-client 的 3D operation 在遠端支援 OpenGL acceleration X-Window Server 執行，再將 3D 物件處理結果以 Video streaming 傳給 thin-client 端，如此可提昇純軟體解 3D 的效能。

但以上兩者對於計畫將採用的平台來說皆不算合適，現今許多 SoC 都已包含 OpenGL Module，連 Samsung 6410 這樣低階的 SoC Microprosser 都支援 OpenGL 了，不好好利用不行。將整合 VirtualGL 把 3D operation 丟給 remote server 去執行的觀念，整合 VMware SGVA Device II Interface 呼叫 thin-client 端的 OpenGL Hardware 進行 3D acceleration。

細節與實作仍規劃進行中～～～

Graphviz

2009-09-14T15:07:00.008+08:00

知道 Graphviz 這玩具已經很久了，不過一直以來沒有直接需求，也就一直沒去了解如何使用。近來因寫論文需要畫些關係圖，上網找了些 Graphviz 的資料，沒想到意外的簡單好用。

DOT文件的寫法相當straightforward，幾篇文章看完就上手了，至於細節的調整則是翻翻 manual 找一下語法就知道。以後關係圖只需要專心用鍵盤打文件，不用花時間抓著老鼠在螢幕上畫來滑去，軟體就該這麼白痴阿！

閒暇之餘也拿了小Q讀書會這次要討論的『貝納德的墮落』來畫了些關係圖，看那 graphviz 所畫出來的曲線，多麼的性感迷人！真不知道以前用 Visio 在畫些什麼鳥。

後記：
發覺 graphviz 無法繪製傳統流程圖如下，希望能列入TODO list，有空的話也會來看看 source code，自己來改寫一下新功能，回饋社群。

apt-build

2009-06-27T10:33:00.001+08:00

不一定要用swiftfox，如果你有apt-build這個程式，也可以自己在家裏面自己編譯最佳化的firefox。

sudo apt-get install apt-build

安裝好之後會問你CPU資訊以及你要強化到什麼程度(英文的訊息)
接著安裝

sudo apt-get build-dep firefox

這會安裝要編譯firefox的相關套件
然後就可以

sudo apt-build install firefox --reinstall

這樣子就會從原始碼開始下載，並且針對你的電腦進行最佳化編譯。

Ubuntu下配置 VM 的bridge上網

2009-06-01T13:53:00.004+08:00

出處: http://tinyurl.com/5ve72w

Ubuntu下配置 VM 的bridge上網方式, 這種方式的優點是:外部主機可以直接訪問guest系統

步驟如下: (以下命令均用root用戶執行)

1. 安裝uml-utilities和bridge-utils和,這兩個工具分別含有tunctl和brctl命令
apt-get install uml-utilities bridge-utils

2. 生成一個新的TAP接口
tunctl -t tap1 -u

這裡是你想用bridge聯網方式啟動VirtualBox的那個用戶的用戶名
比如我的是: tunctl -t tap1 -u ypxing

3. 生成一個叫做br0的bridge
brctl addbr br0

4. 把你的真實網卡設成promiscuous模式,使得它能夠接收發送到別的MAC地址的幀
ifconfig eth0 0.0.0.0 promisc

5. 把你的真實網卡加到bridge br0的一端
brctl addif br0 eth0

6. 把你的真實網卡的配置設置到br0上, 比如我的eth0的ip地址是192.168.168.60
ifconfig br0 192.168.168.60
如果你的是通過DHCP配置的,則執行dhclient br0即可

7. 把上面生成的TAP接口加到 bridge br0的另一端
brctl addif br0 tap1

8. 激活TAP
ifconfig tap1 up

9. 設置/dev/net/tun的讀寫權限
chmod 0666 /dev/net/tun
