CUDA FOR LINUX
1) Download Toolkit for your system
2) Download Drivers for your system
******************************************************************************

Installing OpenCL on Ubuntu Linux with NVIDIA graphics card

Download the CUDA toolkit for Ubuntu from NVIDIAs CUDA site. Open a terminal an run the installation file with the command:

sudo sh cudatoolkit_3.1_linux_64_ubuntu9.10.run

Download the Developer Drivers for Linux at the same website and install it by first stopping X, running the file and start X again. Do stop X use:

sudo /etc/init.d/gdm stop

(lightdm)

Then get a terminal up by pressing CTRL+ALT+F5, login and navigate to where you downloaded the devdriver then type:

sudo sh devdriver_3.1_linux_64_256.40.run

After the driver has been installed start x again by typing

startx

Before compiling an OpenCL application you need to add the path to the lib folder of CUDA to LD_LIBRARY_PATH like so:

export LD_LIBRARY_PATH=/usr/local/cuda/lib64

URI vs URL

Universal Resource Identifier (URI) -
可以識別出某項資源（object, person, or some...etc）的項目可系分為URN, URL
-----URN
-----URL
所以URL是URI, 但URI並不一定就是URLReference:http://en.wikipedia.org/wiki/Uniform_resource_identifier http://en.wikipedia.org/wiki/Url

Regular expression

Character classes
.	any character except newline
\w \d \s	word, digit, whitespace
\W \D \S	not word, digit, whitespace
[abc]	any of a, b, or c
[^abc]	not a, b, or c
[a-g]	character between a & g
Anchors
^abc$	start / end of the string
\b	word boundary
Escaped characters
\. \* \\	escaped special characters
\t \n \r	tab, linefeed, carriage return
\u00A9	unicode escaped ©
Groups & Lookaround
(abc)	capture group
\1	backreference to group #1
(?:abc)	non-capturing group
(?=abc)	positive lookahead
(?!abc)	negative lookahead
Quantifiers & Alternation
a* a+ a?	0 or more, 1 or more, 0 or 1
a{5} a{2,}	exactly five, two or more
a{1,3}	between one & three
a+? a{2,}?	match as few as possible
ab\|cd	match ab or cd

我們可以使用預先定義的字元類別：

.	符合任一字元
\d	等於 [0-9] 數字
\D	等於 [^0-9] 非數字
\s	等於 [ \t\n\x0B\f\r] 空白字元
\S	等於 [^ \t\n\x0B\f\r] 非空白字元
\w	等於 [a-zA-Z_0-9] 數字或是英文字
\W	等於 [^a-zA-Z_0-9] 非數字與英文字

. 符合任一字元。例如有一字串abcdebcadxbc，使用.bc來比對的話，符合的子字串有abc、ebc、xbc三個；如果使用..cd，則符合的子字串只有bcd。

以上的例子來根據字元比對，您也可以使用「字元類」（Character class）來比較一組字元範圍，例如：

[abc]	a、b或c
[^abc]	非a、b、c的其它字元
[a-zA-Z]	a到z或A到Z（範圍）
[a-d[m-p]]	a到d或m到p（聯集）
[a-z&&[def]]	d、e或f（交集）
[a-z&&[^bc]]	a到z，除了b與c之外（減集）
[a-z&&[^m-p]]	a到z且沒有m到p（a-lq-z）（減集）

一次只指定一個字元不過癮，也可以用Greedy quantifiers來指定字元可能出現的次數：

X?	X出現一次或完全沒有
X*	X出現零次或多次
X+	X出現一次或多次
X{n}	X出現n次
X{n,}	X出現至少n次
X{n,m}	X出現至少n次，但不超過m次
