I don’t know if it’s the correct way… just opted for that because I want share some content that aren’t integrated with Facebook API.

I’m not in favor of disposable objects, even for not short-term durability like mostly gadgets today.  Indeed every two or three years the technologies change forcing us to adapt. If you bought low quality designs you are accelerating this process not to mention that the true usability goes away. Watch your needs before buy, not always the most hardware capable is the best option, but poors designs always affect in some way…

Download the script here.

Just run passing the URL, for example:

$ python u.py www.coding.com.br

http://u.nu/72mpd

Easy your life by putting the script on your $PATH and execution (+x) file mode. Worth check the API from other services:

• bit.ly
• migre.me (brazilian company)
• is.gd
• tiny.cc
• tinyurl

For simple variables types like int or float is just equal to 0 or 0.0 respectively. Now, suppose that you have a “large” struct and doesn’t want to set each member  individually… you could just type “={0}” which means that the first member is explicitly initialized to zero and the remaining members are implicitly initialized, also zero. Let’s see an example:

typedef struct
{
int a;
char c;
char s[10];
int *ptr;
} data;

When you initialize with:

data d;

You got some random value like:

{a = -1208298748, c = -12 ‘\364′, s = “\317\372\267\230\353\377\277\351\203\004″, ptr = 0xb7e94cc5}

When you type:

data d = {0};

You’ll have each struct member initialized to zero.

{a = 0, c = 0 ‘\000′, s = “\000\000\000\000\000\000\000\000\000″, ptr = 0×0}

You can learn much more about designated inits [section 6.26] on GCC docs.

I haven’t found the solution for my problem (for wordpress, drupal and joomla there are so many) so I resolved it and now I’m posting if somebody can’t do it or just wanna some copy/paste

 location ~ ^/wiki {
 	root /path/to/wiki;
 	index wikka.php;
 
 	if (!-e $request_filename) {
 		rewrite ^/wiki/images/(.*)$ /images/$1 break;
		rewrite ^/wiki/templates/(.*)$ /templates/$1 break;
 		rewrite ^/wiki/3rdparty/plugins/freemind/(.*)$ /3rdparty/plugins/freemind/$1 break;
 		rewrite ^/wiki/3rdparty/plugins/wikkaedit/(.*)$ /3rdparty/plugins/wikkaedit/$1 break;
 		rewrite ^/wiki/(.*)$ /wiki/wikka.php?wakka=$1 break;
 		break;
 	}
 }

A brief explanation:

on line 1 we setup where our wiki is located, on our case /wiki, so in line 2 we give full path to where the wiki’s file are located on the filesystem and line 3 we says our index will be wikka.php once Wikka Wiki just redirect index.php to wikka.php (ok I don’t mind why they don’t put the contents of wikka.php on index.php and its over ).

line 5-12 we configure the rewrite rules, on line 5 is the condition what to do when there is no file or symbolic link when a URL is acessed, if its matched the following rules are processed:
line 6-10: rules to ensure that static content like css, js and images won’t be redirected to wikka.php.
line 11: the main rule, that will redirect all URLs to wikka.php so it process and show the output for each wiki page.

I don’t why (I’m new to Nginx) even using the condition if(!-e $request_filename) I need to put the rules to ensure that static content will be reached, if I discover, I update this post, but these rules are working for me under Nginx 0.7.67 and Wikka 1.2-p1
