You want the "popen" function. Here's an example of running the command "ls /etc" and outputing to the console.

popen(3) - Linux man page
The popen() function opens a process by creating a pipe, forking, and invoking the shell. Since a pipe is by definition unidirectional, the type argument may specify only reading or writing, not both; the resulting stream is correspondingly read-only or write-only.

clientHeight、offsetHeight 和 scrollHeight

2010-01-07T19:40:00.005+08:00

四種瀏覽器對 document.body 的 clientHeight、offsetHeight 和 scrollHeight 的解釋
clientHeight 大家對 clientHeight 都沒有什麼異議，都認為是內容可視區域的高度，也就是說頁面瀏覽器中可以看到內容的這個區域的高度，一般是最後一個工具條以下到狀態欄以上的這個區域，與頁面內容無關。

offsetHeight IE、Opera 認為 offsetHeight = clientHeight + 滾動條 + 邊框。 NS、FF 認為 offsetHeight 是網頁內容實際高度，可以小於 clientHeight。

scrollHeight IE、Opera 認為 scrollHeight 是網頁內容實際高度，可以小於 clientHeight。 NS、FF 認為 scrollHeight 是網頁內容高度，不過最小值是 clientHeight。

YUV / RGB

2009-06-06T14:41:00.000+08:00

YUV and Y'UV were used for analog encoding of color information(TV).
YCbCr was used for digital encoding of color information(images or videos).

In computers, we actually need RGB -> YCrCb

Y = (0.257 * R) + (0.504 * G) + (0.098 * B) + 16

Cr = V = (0.439 * R) - (0.368 * G) - (0.071 * B) + 128

Cb = U = -(0.148 * R) - (0.291 * G) + (0.439 * B) + 128

Webkit on windows

2009-05-19T10:35:00.004+08:00

1. Installing the Developer Tools

VS 2005 Team Suite or VS 2005 Express
Cygwin
QuickTime SDK

2. Getting WebKit

You can download the nightly builds from WebKit Nightly Builds, snapshot of the WebKit source tree, or SVN.

You will need to switch some libraries, too. Read this from A Redistributable WebKit by Brent @ http://lwat.blogspot.com. The files are the latest releases provided by the author.

You should also download the WebKit Support Libraries. Read here for more information.

Put the extracted files to WebKitLibraries\win

After you switch the libraries, the built browser will be slightly different from the Apple Safari.(Of course, you change the libraries)

Type the command to update the WebKit tree in cygwin

$ WebKit/WebKitTools/Scripts/update-webkit

3. Building WebKit

Open Webkit.sln or using cygwin by following the steps of tutorial to build the webkit project.

If you switched the libraries in Step 2, you need to reference here to modify your own source codes. You need to modify the reference of those proprietary libraries.

Install Ubuntu inside Windows

2009-04-30T13:33:00.005+08:00

Some may ask why you need to install the new one, wasn't the old version worked fine? I must confess that I just want to try the latest version: Ubuntu 9.04.

The original 7.10 version had no good support on ATI graphic cards and I installed a open source driver fglrx.

After online updates to 8.04 and 8.10, the old driver could not work well. It ran in only Ubuntu low-graphic mode. At that time I thought it may be okay to continue and I kept on updating to 9.04.

However, after rebooting to finish updating, I couldn't even see the login menu.

Since I have driver problem, CD-ROM problem, I need to install by some other method. My computer had dual OS and I can use this advantage.

First I fixed the MBR to boot from Windows XP only. Later I delete the Ubuntu partition and formatted as NTFS drive.

Login to Windows and put the Ubuntu 9.04 CD to the external CD-ROM. Select Install inside Windows in the Ubuntu CD menu and set essential parameters. After the data all copied to your disk, you can reboot the system. Now the Windows Boot Manager will be shown and you can choose Ubuntu to finish the installation.

If you want to uninstall the Ubuntu, you can remove it from Windows Add/Remove Programs. It it easy, isn't it.

CSS selectors

2009-03-25T16:48:00.005+08:00

I just read the ">" and "+" symbol in CSS. So I found some reference to understand how it works. If the simple example is too simple to understand, please reference the hyperlinks.

wide range selectors

h1, h2, h3, h4 { text-align: center; }
.highlight p, .highlight ul { margin-left: 10px; }
#main p { padding-top: 10px; }

type selectors(element selectors)

h1 { text-align: center; }

class selectors

/*simple class selector*/
.big { text-align: center; }
<p class="big">This is some text</p>

/*combining class and type selectors*/
p.big { color: blue; }
div.big { color: red; }

/*combining multiple classes*/
.big { font-weight: bold; }
.indent { padding-left: 2px; }
<p class="big indent">

ID selectors

#navigation { width: 50%; color: #333; }
div#navigation { width: 50%; color: #333; }

descendant selectors

p span { color: red; }
<p>This is a <span>test</span></p>

child selectors

p > span { color: red; }
<p>This is a <span>test</span></p>
<span>outside p element test</span>

NOTE: not supported by Windows Internet Explorer 5, 5.5 and 6

Adjacent sibling selectors

p + span { color: red; }
<p>This is a <span>test</span></p>
<span>outside p element test</span>

NOTE: not supported by Windows Internet Explorer 5, 5.5 and 6

Attribute selectors

input[type=text] { width: 50%; }
<input type="text" value="text" />
<input type="button" value="button" />

NOTE: not supported by Windows Internet Explorer 5, 5.5 and 6

Pseudo-classes

/*element hierarchy*/
:first-child
/*hyper link styling*/
:link
:visited
/*mouse over*/
:hover
/*mouse down*/
:active
/*other*/
:focus
:lang(n)

NOTE: not supported by Windows Internet Explorer 5, 5.5 and 6

Pseudo-elements

/*the first letter or the first line of text appears*/
:first-line

I2C, GPIO

2009-03-25T10:11:00.004+08:00

I²C (Inter-Integrated Circuit) is a multi-master serial computer bus.
Read Wikipedia and I2C匯流排介面單元.ppt for more information.

GPIO (General Purpose I/O), can act as input, to read digital signals from other parts of a circuit, or output, to control or signal to other devices. They are similar to 8051 P0 - P3.
Read Wikipedia for more information.

Heard this many times, but don't know exactly what they are.

Hide XP/Vista Disk 將磁碟機藏起來

2009-03-12T13:46:00.002+08:00

Hide your disk in My Computer(XP and Vista)
隱藏磁碟機的方法(XP/Vista皆適用)

1. delete the drive letter 刪除磁碟機代號
　　Open the "Computer Management", see "Storage - Disk Management" and delete the drive letter assigned to the drive you want to hide. Then reboot your system. The drive should be hidden. If you want to restore the drive back, just reverse the action you just did.
　　打開「電腦管理」。在「存放裝置-磁碟管理」的地方，將欲隱藏磁碟的磁碟機代號刪除，重開機後硬碟就不見囉。若要恢復使用該硬碟，則把該磁碟加上磁碟機代號。
　　資料參考：重灌狂人 - 如何「隱藏」電腦中的磁碟機？

2. Use Register Editor 使用登錄檔
　　Add a DWORD value named "NoDrives" in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer.(Create it if not exists) Then modify the value of "NoDrives". (see here to get the mapping of drive letter and value. Try decimal, not hexadecimal.)
　　在 HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer 中增加一個名字為 NoDrives 的 DWORD 值，以十進位的方式填入欲隱藏的磁碟機代號的數值。數值請參考這裡。
　　資料參考：Breezy Dream - 硬碟不想給人看?把你XP的硬碟藏起來!

Python Built-in Types

2009-03-11T20:21:00.005+08:00

Built-in Types

Numeric — int, long, float, complex

type	description
int	plain integers
long	long integers
float	floating point numbers, here is some additional methods
complex	complex numbers. To extract these parts from a complex number z, use z.real and z.imag.

Sequence Types — str, unicode, list, tuple, buffer, xrange

type	description
str	strings. Some methods are listed below, or read String Method for more infomation.
unicode	Unicode strings. much like strings, but are specified in the syntax using a preceding `'u'` character: `u'abc'`, `u"def"`.
list	lists, constructed with square brackets, separating items with commas.
tuple	tuples, constructed without square brackets, separating items with commas
buffer	buffers, not directly supported by Python syntax. read buffer() to get details
xrange	xrange objects, similar to buffers. read xrange() to get details

String objects

#Return a string with first character capitalized.
#similar to css text-transform
str.capitalize()
str.lower()
str.upper()
str.swapcase()

#get the first index of the substring
str.find(sub[, start[, end]])
# similar to find(), but raise ValueError if not found.
str.index(sub[, start[, end]])
#search from the end to the start
str.rfind(sub[, start[, end]])
str.rindex(sub[, start[, end]])

#replace the old substring with the new substring
str.replace(old, new[, count])

#split the string with separator
str.split([sep[, maxsplit]])
str.splitlines([keepends])
str.rsplit([sep[, maxsplit]])

#remove the leading and trailing characters
#you can specify characters to remove from the leading and trailing
str.strip([chars])

Extended read: String Formatting Operations

Lists objects
Fredrik Lundh - An Introduction to Python Lists

#To create a list
L = []
#OR
L = list()

#To get the length of an unknown size array
n = len(L)

#Add items to list
L.append(item)
L.extend(sequence)
L.insert(index, item)

#Sort the list
L.sort()

Extended read: Mutable Sequence Types

File Objects

#open the file, similar fopen in C

#write to file
file.write(str)
file.writelines(sequence)

#close the tile
file.close()

Ubuntu user directory mapping

2009-03-02T17:09:00.003+08:00

You can change your own directory mapping if you don't like the default folders.(Maybe it was named by system which you were not satisfied.)

　　$ vi ~/.config/user-dirs.dirs

# find the follow
XDG_DESKTOP_DIR="$HOME/Desktop"
#modify the path to your folder
XDG_DESKTOP_DIR="$HOME"

You can change your own directory mapping for the rest of folders in the file. After you modify the file, restart your GNOME session.(Press Ctrl + Alt + Backspace)

Ubuntu 8.10 破音問題

2009-02-16T09:17:00.004+08:00

灌了Lazybuntu裡頭建議的影音播放軟體後
聲音就沒正常過= = 感覺是設定的問題
上網找了幾個解決方法目前有效的是第一個!

Ubuntu 8.10下播放MP3音效輸出產生破音的解決[圖文]
如果你在使用Ubuntu8.10的過程中，也有被破音困擾過，那就試試下面介紹的方法。
雙擊通知欄區域的喇叭圖標，試著把PCM調到70％左右，測試啟動音樂，沒破音了吧，就這麼簡單。

Ubuntu audio problem
If you heard a lot of noises playing audios, try to adjust your Sound Setting. Set PCM to about 70% as the figure shown, then try to test again. The noises should be disappeared. This method is useful to me, or you may try the following steps.

Ubuntu音效問題 - U型遊樂園
　　$ cd /etc/init.d
　　$ sudo gedit soundstartfix

#!/bin/bash
kill $(lsof -t /dev/dsp* /dev/audio* /dev/mixer* /dev/snd/*)

JavaScript Event object

2009-02-13T09:18:00.005+08:00

Firefox can not use the event object in JavaScript
I often use the first arguments to get the event object.

obj.onmousedown=function() {
var event = arguments[0];
var x=event.clientX, y=event.clientY;
}

<div onmousedown="_mousedown(event)"></div>
<script type="text/javascript">
function _mousedown(e) {
var x=e.clientX, y=e.clientY;
}
</script>

            printf("PARENT: My child's PID is %d\n", pid);
            printf("PARENT: I'm now waiting for my child to exit()...\n");
            wait(&rv); /* wait until child leave */
            printf("PARENT: My child's exit status is: %d\n", WEXITSTATUS(rv));
            printf("PARENT: I'm outta here!\n");
    }
    return 0;
}

Linux / Unix Command: execvp
The exec family of functions replaces the current process image with a new process image. So if you want to execute a command in a application, better use fork() to create a child thread.

setup vnc4server

2009-01-23T10:42:00.004+08:00

reference from Ubuntu Forums
HOW TO: setup vnc4server

1. setup XDMCP:
　　click System -> Administration -> Login Window
　　click Remote tab
　　select "Same as Local"
　　click "Configure XDMCP"
　　remove check from "Honour indirect requests"

2. configure remote greeter:
　　$ sudo gedit /etc/gdm/gdm.conf

find the following:
　　(1) [xdmcp] section, set enable as true
　　　　　Enable=true
　　(2) # RemoteGreeter=/usr/lib/gdm/gdmlogin
　　　　　enable it(remove the comment)

3. Install required packages:
　　$ sudo apt-get install vnc4server xinetd

4. Set the VNC passwd
　　$ sudo vncpasswd /root/.vncpasswd

5. Define the VNC service criteria:
　　$ sudo gedit /etc/xinetd.d/Xvnc

service Xvnc
{
    type = UNLISTED
    disable = no
    socket_type = stream
    protocol = tcp
    wait = yes
    user = root
    server = /usr/bin/Xvnc
    server_args = -inetd :1 -query localhost -geometry 1024x768 -depth 16 -once -fp /usr/share/X11/fonts/misc -DisconnectClients=0 -NeverShared passwordFile=/root/.vncpasswd -extension XFIXES
    port = 5901
}

Save it!

NOTE: You can change the port number here, it changes what you use to connect to the server. For example, if you chose port 5959, you can connect to your Ubunutu using RealVNC on Windows XP by typing: 192.168.0.101:5959

6. Reinitialize the service with new criteria:
　　$ sudo /etc/init.d/xinetd stop
　　$ sudo killall Xvnc
　　$ sudo /etc/init.d/xinetd start

7. Test the connection:
　　$ vncviewer localhost:1

How to compile Firefox scriptable plugin NPRuntime in Ubuntu

2008-12-19T16:46:00.003+08:00

How to compile Firefox scriptable plugin "npruntime" in Ubuntu

You will need the Firefox source codes. The source files require more than 200M space. You can download from Mercurial for the latest version or mozilla.org for old versions.

1. Install the Linux Build Prerequisites

Install the Linux Build Prerequisites. The following commands are used for Ubuntu.

　　$ sudo apt-get build-dep firefox
　　$ sudo apt-get install mercurial libasound2-dev libcurl4-openssl-dev

　　(The following commands may be optional to your environment)
　　$ sudo apt-get install autoconf2.13
　　$ sudo apt-get install libdbus-glib-1-dev

For more information, please reference the Linux Build Prerequisites

2. Download the mozilla source code

Download the mozilla source code from Mozilla Source Code (Mercurial) (The latest version)

　　$ hg clone http://hg.mozilla.org/mozilla-central/ mozilla
　　$ cd mozilla

If you do not want to download the latest version, you can get old versions from mozilla.org(HTTP)

Note: Now the mozilla-central repository in Mercurial is the Firefox 3.1 source code. See Firefox 3.1 for developers for more information.

3. Add path to modules/plugin/sdk/samples/npruntime

Modified the toolkit/toolkit-makefiles.sh, attach the folder path to the npruntime folder in the array MAKEFILES_plugin

　　$ vi toolkit/toolkit-makefiles.sh

MAKEFILES_plugin="
　　modules/plugin/sdk/samples/npruntime/Makefile
"

　　(The path may be different. Please check your source files.)

This will make the ./configure to build the Makefile based on the Makefile.in

4. Using a .mozconfig configuration file.

This configuration file will help us to setup the build options.

Example .mozconfig file to build Firefox, Default Release Configuration

. $topsrcdir/browser/config/mozconfig
mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/ff-opt
ac_add_options --disable-tests

Note: If you use the upper example .mozconfig file, please make a new folder name "ff-opt" for MOZ_OBJDIR.

　　$ mkdir ff-opt

Please read Configuring Build Options for further instructions.

5. Generate the Makefile

You need autoconf to generate ./configure file if not exists. You may need to export AUTOCONF=autoconf2.13 in your environment
　　$ autoconf　(optional)
　　$ ./configure

The Makefile will be generated in the MOZ_OBJDIR folder. If you followed the instructions above, that will be "ff-opt".

Note: Mozilla suggests you should re-configure in the MOZ_OBJDIR folder. See Building with an Objdir for more information.

6. Build the firefox

You can build the plugin before you make the Firefox build. But the Makefile will try to install the built plugin(.so) to MOZ_OBJDIR if you followed the procedure. If you just need the plugin, you can ignore the error and bypass this step.

　　$ cd (your source root folder)
　　$ make -f client.mk build

That may cost more than 40 minutes, depending on your machine ability.

The executable Firefox can be found in MOZ_OBJDIR/dist/bin

Please read Build and Install for more information.

7. Build npruntime

　　$ cd modules/plugin/sdk/samples/npruntime
　　(The path may be different. Please check your source files.)
　　$ make

The plugin(.so) will be installed automatically. You can now run the Firefox and type "about:plugins" in the Location bar. The available plugins will be listed.

個人化的正義觀
網路是很可怕的媒介一下子會聚集來各式各樣的反應

我覺得這作者寫的還不錯剛剛看完了底下三篇文章
微軟對於電腦資訊產業的貢獻是無法從歷史上抹滅的
微軟一開始的低姿態就算是東抄西拼 bug一堆
還是能再再的簡化電腦的操作把電腦推到了每個人的家裡

工作上同時接觸到微軟Windows系統以及Linux系列的自由軟體
之前和主管聊到開發微軟的東西就是比開發Linux的東西要簡單得多
Open source雖然成本低但是常常會有求助無門的時候
在微軟的平台上作東西有問題做不出來至少還能推給微軟XD
加上開發文件大多在MSDN上有比起東有一篇西有一段的Linux實在好太多

我也不隨便推薦東西給人家大多提出幾個可能的解決方法
真正試用過好用才會推薦給別人用讓他用看看好不好用
尤其在這種時代許多東西都怕用了會侵權無不小心謹慎
自由軟體並非不好有很多比起Windows內建功能要好很多的東西
但使用習慣上可能略有不同只是人很怠惰不喜歡改變習慣
話說微軟也有不少作的很不錯的軟體!
每個人都努力過怎可輕易抹煞其他人的成果!

我也放出過我自己寫的程式在自己有工作平常回家想休息的情況下
要兼職的維護這些自由軟體是還蠻累的加上又賺不了錢= =
我可以體會那種感覺哈~

讓妳婚禮這一天看起來像自己…

2008-10-27T16:36:00.002+08:00

NOWnews記者葉卉軒／台北報導

最美的新娘，應該在婚禮這一天，看起來像自己…。

根據一份調查發現，70%的新娘，婚禮當天使用的彩妝，不僅將是重要回憶的一部份，更會成為她日後彩妝習慣的一部分，舉凡眼影、粉底或口紅，都將伴隨著她出席接下來的各種場合。

一般新娘彩妝只著重將新娘「打造」成完美女人，卻忘了新娘最美的表情其實是原來的自己。對此，Bobbi Brown品牌經理陳怡靜表示，結婚是人生旅途上最神聖的日子，重要的時刻最需要搭配頂級彩妝及婚紗。

陳怡靜並進一步提到，持久及防暈染是新娘彩妝最需要注意的兩大重點，因此「幸福美妝隨身組」內含BOBBI BROWN 明星商品「流雲眼線膠」及勾勒電眼的「輕巧精細眼線刷」及「揮別暈染睫毛膏」。另外更有象徵純白淨雅的象牙白「微煦眼影」，甜美的糖粉紅「星紗亮唇蜜」，BOBBI BROWN將這些幸福的色彩通通收納在一只純白化妝包裡，要讓新嫁娘將甜蜜的回憶化為能延續到永遠的美麗。

此外，BOBBI還提供新嫁娘們10個能夠優雅又從容的彩妝步驟。首先，由於鎂光燈會使肌膚呈現粉紅色調，使用膚色基調的底妝，BOBBI BROWN建議從唇邊與鼻翼周圍的泛紅處開始按壓，再均勻地塗抹全臉，創造出最沒有妝感的底妝。並記得要以蜜粉定妝、維持遮瑕的持久度，再以吸油面紙除去多餘的油脂，確保照片中的妝容不會面泛油光。若禮服較為低胸，則建議使用修容餅修飾露出的頸部，並以經典明星星紗顏彩盤打亮，增加光澤感和立體感。

且務必使用防水防暈染的眼線與眼影，以免婚禮當日感動的淚水弄髒了眼妝，眼妝色彩完成後打亮眉骨以及眉部外緣，創造明亮的立體眼妝。

至於腮紅，則建議先以自然色調的腮紅從笑肌處刷至髮際，並向下刷勻，再用另一款亮色調的腮紅打亮肌處。運用雙層腮紅，打造持久的亮麗氣色。此外，BOBBI BROWN也提醒，中間色調的唇色在拍照時不易顯色，應選擇高於平常使用的顏色一~二色度的唇彩。粉紅色、玫瑰色、以及酒李紅的顏色是最佳選擇。且記得在上唇膏前先以唇線筆勾勒並填滿雙唇，以確保唇彩的持久與立體。

另，婚禮當天要記得隨身美麗工具箱，放入重要的彩妝品。記得加上小小針線包，可以在不小心勾壞蕾絲及肩帶脫落時給你最大的幫助。攜帶衣物專用的黏毛刷，去除衣服上沾黏的棉絮或線頭。準備一包濕紙巾，方便清潔彩妝或食物的污漬。

最後，深呼吸別緊張，張開手擁抱妳的幸福吧！

對不起，我只是在勾引妳

2008-10-24T23:48:00.000+08:00

對不起，我只是在勾引妳

一個男網友的心情自白...明白反映了網路世界的現實...
看完這篇文章妳有什麼感想？網路世界真真假假，別被迷惑了，隨時記得清醒吧！

　　請允許我說一聲對不起，因為妳愛上我那不是我的錯，我不過是在勾引妳。

　　記得妳加了我之後的第一次聊天，妳的單純和可愛讓我決定暫停遊蕩的腳步。於是，我停止了我像獵人一樣在網路里逡巡的活動，開始天天陪著妳。

　　以我混論壇五年的經歷，以我生活了三十五年的閱歷，我覺得妳真的很單純，因為妳的笑妳的生氣全是即興而來；以我聊天五年閱人無數的經驗，妳也是狠可愛的，因為妳的率性妳的小女人的聰明都在一顰一笑裡。

　　喜歡上妳的單純和可愛了。於是，我決定勾引妳。

　　一個只有我們兩人的深夜，在音樂裡，一些淡淡的憂傷飄蕩在夜裡。妳在這憂傷的音樂裡向我訴說了妳生活裡的許多無奈，在妳的訴說中，我用憐愛的語氣叫妳丫頭，用擁抱的符號給妳安慰。在妳敞開心扉的同時讓我的溫柔悄悄的駐進了妳的心裡。其實，這不過是我慣常的手段而已。

　　然後，我用一種不容抗拒的語氣問妳要了妳的電話號碼。接下來的時間裡，我除了每天出現在網路里，還每天用電話給妳一個問候。憂傷的女人需要溫暖，所以我的問候恰到好處。

　　當又一個深夜來臨的時候，我愛憐的說：關了妳的電腦，我給妳打電話。

　　我知道，妳是寂寞的。所以深夜的電話無疑會給妳許多的安慰。其實誰都知道這些電話裡暗藏了許多的曖昧，但是妳脆弱寂寞的心靈已經來不及分辨。當曖昧一開頭，便會有烈火燃燒起來。終於，在我呢喃的情話裡，妳被我點燃了。

　　女人是感性的，她會在慾望裡燃燒起熊熊的愛火。

　　男人是理性的，他只會讓慾望熊熊燃燒。

　　妳愛上我了。然後，妳便依賴於我，所以妳期望把妳的喜怒哀樂全都繫在我身上。可是，我只是網路里的過客，我只想讓妳取悅我的生活，或是娛樂我片刻的身體，所以，我不想承受妳的喜怒哀樂。

　　請原諒，我只是在勾引妳，所以，當我勾引成功以後，我就會在勝利以後厭倦這次勾引並以極快的速度逃開。所以，當妳愛上我的時候，我只有躲避。網路里花開繁茂，我怎能駐足在一朵花前而棄暗香無數？

　　對不起，我只是在勾引妳！
