The new system (which I call Marwin AMS) is still under development, but is stable and has enough features to be released. It’s written from scratch by me with PHP, bash scripts and a MySQL database on the backend and XHTML, CSS and JavaScript (jQuery) on the frontend. New and improved features (implemented or planned) on the site includes, but is not limited to:

• Play-Penis Points™
• Advanced Forums System
• Notifications API
• FTP / Image Uploader integration
• Game Server Management
• Event Planner / Calendar
• Minecraft Statistics and Achivements
• User Quote Database
• Photo Gallery

Playback Spelförening is a non-profit association founded in 2008 which I’ve been the chairman of during 2008, 2009 and 2011. Our main purpose is to host LAN Parties and other gaming related events, and since most of the members are old buddies from high school, it’s a great way to keep in touch!

During 2010 Playback bought a server (to host game servers, user-uploaded files etc.), which greatly boosted the user activity online, so the main focus of the new site was to help the members to interact with the server and develop new features which integrated with our various services.

As I said above, the site is still under active development – so check back often to see our new awesome site come to life!

I give you Minify, a script which combines and compress your files on the fly. This way the files get smaller and the client only have to make one request to the server. Just include the class in the top of the page, somewhere before you include your CSS/JavaScript, give it a few parameters and it will do everything for you. Now you can have how many files you want and edit whenever you want as long as you include the CSS/JavaScript file generated by Minify.

But, won’t it slow down the execution of the page to run Minify every time? No! First of all, you’ll barely notice when the script actually runs because it doesn’t take any time at all. And second, it won’t run the script if there is no change to the source files. The script is smart enough to store the hash of every file in a cache file and will just check against it.

I made the function which Minify is based on a few months ago when I tried to figure out a way to compress my files automatically and I’ve used it for two or three projects. I realized that there should be an easier way to integrate the script into an existing code and that’s why I made Minify. The original script used PHP’s function filemtime() to check if a file had been modified since the minified version was generated. It work decently, but if you copy/paste an old file from another project it will still have the same modified time and therefore will the minified version be newer. This and a lot of other stuff were fixed when I changed to the existing system, which is faster too!

So, what’s next for Minify? Well, first of all I want to fix all the issues listed below and more optimization. A nice thing would be native JavaScript and CSS compression in Minify.class.php to keep it in one file. Can you think of something else to add? Suggest it!

Please comment below what you think about the script. Don’t be afraid to report issues, improvements, feedback etc. below and remeber to tell your friends!

function password($password, $username, $saltglob = '2c62f9eb917de737b8184b8e5a793c89') {   
 
	/* save string length of username, password and salt */
	$userlen = strlen($username);
	$passlen = strlen($password);
	$saltlen = strlen($saltglob);
 
	/* split username, password and salt into string length + 1 */
	$user = ($userlen < 4) ? array($username, $username) : str_split($username, ($userlen/2)+1);
	$pass = ($passlen < 4) ? array($password, $password) : str_split($password, ($passlen/2)+1);
	$salt = ($saltlen < 4) ? array($saltglob, $saltglob) : str_split($saltglob, ($saltlen/2)+1);
 
	/* save ascii value of username, password and salt */
	$userval = ord($username);
	$passval = ord($password);
	$saltval = ord($saltglob);
 
	/* prepare an array of arguments and a format for vsprintf */
	$format = '%s%s%s%s%s%s%s%s%s%s%s%s%s%s%s';
	$args   = array($username, $userlen, $passlen, $saltlen, $saltglob, $user[0], $user[1], $pass[0], $pass[1], $salt[0], $salt[1], $userval, $password, $passval, $saltval);
 
	/* vsprintf the arguments */
	$string[] = vsprintf($format, $args);
 
	/* rsort the arguments and run vsprinf again */
	rsort($args);
	$string[] = vsprintf($format, $args);
 
	/* sort the arguments and run vsprintf again */
	sort($args);
	$string[] = vsprintf($format, $args);
 
	/* hash each vsprintf result with md5 (raw) */
	foreach($string as $value)
		$password = hash_hmac('md5', $value, $password, true);
 
	/* hash	with sha512 (raw) */
	$password = hash_hmac('sha512', $password, $saltglob, true);
 
	/* return an md5 hash */
	return hash_hmac('md5', $password, $username);
 
}

This way, even if someone can produce a bruteforce against the algorithm they will never know where in the hash the salt pieces where placed. And of course we’ll salt it with a global salt (third parameter) which is hidden deep in a configuration file on our server, which requires the script kiddie to actually access your files to get it.

One thing’s for sure, I’ll use this for all my projects .

Edit: This function has been updated several times since the initial post because I like to make stuff more complicated than they actually have to be. The most recent one is the one above though (and is kinda overkill)

This site is not finished yet, but will be in the upcoming weeks. The plan is to test the system a few months and then, if the site gets popular, expand to more games such as Modern Warfare 2 and Counter-Strike. Design is once again done by Fredrik Larsson.

This is one of my first released php sites so I feel some kind of proudness over it, even though it’s kind of messy and un-optimized. Design, XHTML and CSS made by Fredrik Larsson, who is the secretary of the association.

serieous.se is mainly a Swedish news site which post news and rumors about (mostly) American TV-shows e.g. Lost, Heroes, Family Guy. Around this news site we’ve build up a community with profiles, guest books, forums etc. There’s also an archive with downloadable files, an information page about every show and much more!
