Serve JAD files OTA with PHP

Sime — Mon, 03 Nov 2008 17:14:41 +0000

Some handy code to dynamtically serve JAD files for OTA installation. The below script sets the appropriate headers types, also tidies up the JAD file removing stray characters which can cause issues and setting the correct file paths internally.

Place the PH script in a root directory as serveJAD.php. Place your JAR and JAD files in a subdirectory /J2ME

Call the script by serveJAD.php?format=J2ME&file={jad minus extension} or you can use the Apache rewrite below and call as /J2ME/file.jad

serveJAD.php?format=J2ME&file=game

or with Apache rewrite

/J2ME/game.jad


	$format   = $_GET["format"];
	$file     = $_GET["file"].".jad";
    header("Cache-Control: no-cache, must-revalidate,no-transform" );
    header("Pragma: no-cache" );
	header("Content-type: text/vnd.sun.j2me.app-descriptor");
	header("Content-Disposition: attachment; filename=".$file.";");
	$jad = file_get_contents("./".$format."/".$file);
	$lines = explode("\n",$jad);
	$final = "";
	foreach($lines as $line){
		$line = trim($line);
		if(strlen($line)>0){
			$keypair = explode(": ",$line);
			if($keypair[0]=='MIDlet-Jar-URL' || stristr($keypair[0],"RIM-COD-URL")){
				$url = trim($keypair[1]);
				if(!stristr($url,"http:")){
					$keypair[1] = "http://".$_SERVER["HTTP_HOST"]."/$format/".$url;
				}
			}else if($keypair[0]=='MIDlet-Jar-Size'){
				$keypair[1] =  filesize("./".$format."/".$_GET["file"].".jar");
			}
 
			$line = join(": ",$keypair);
			$l = trim($line);
			if(!empty($final))$final.="\n";
			$final.=$l;
		}
	}
	print($final);
?>

RewriteEngine On RewriteRule /J2ME/(.*)\.jad /serveJAD.php?format=J2ME&file=$1

You can also use this to build automatic index pages, using this as dir.php?format=J2ME


	$format   = $_GET["format"];
	$scanthis = "./".$format;
 	$scanlisting = scandir($scanthis);
    $dirlisting = array();
    foreach($scanlisting as $key => $value){
		if(stristr($value,"jad")){
			$name = explode(".",$value);
			$dirlisting[$name[0]] = $name[0];
		}
	}
	ksort($dirlisting);
?>

http://www.time-safe.com provides URL shortening, but also allows you to specify passwords and time ranges for the URL forwarding.

Delete a tag in Javascript

I use with with AJAX library to completely remove a DIV tag ( or whatever )

function removeTag(tag){ field = document.getElementById(tag); field.parentNode.removeChild(field); }

function removeAllChildren(field){ if ( field.hasChildNodes() ) { while ( field.childNodes.length >= 1 ) { removeAllChildren(field.firstChild); field.removeChild(field.firstChild); } } }

Black screen when playing all video in Windows

Sime — Thu, 04 Sep 2008 19:00:30 +0000

So, the other night I decided to clean up my PC and install XP Service pack 3, update my ATI drivers etc etc.

After the reboot, went to play some of my videos, only to find the video display to be black. Audio was fine, everything looked dandy. VLC, Media Player, Nero all refused to show the video.

Doubling checking the codecs, everything looked fine.

The solution - in the back of my head I remembered settings in the Catalyst Control Center. Look under VIDEO and then BASIC color. For some reason, USE APPLICATION SETTINGS was unchecked, and the brightness turned down to zero. I still can’t set it back up higher, but checking the USE APPLICATION SETTING box fixes the issue.

Blocking the searchme.com bot

Sime — Tue, 15 Jul 2008 07:04:49 +0000

Nice idea for a search engine, however, their bot is a disrespectfull bastard, doesn’t obey robots.txt, plus as it’s a visual search engine, processes Javascript tracking which throws your stats off.

Block it using iptables thus

iptables -I INPUT -m iprange --src-range 165.193.254.1-165.193.254.254 -j DROP
iptables -I INPUT -m iprange --src-range 208.111.154.1-208.111.154.254 -j DROP
