Fatal error: Call to undefined function _user_password_dynamic_validation() in /var/www/localhost/htdocs/drupal/install.php on line 727

It can be solved by modifying the system table of your Drupal database:

mysql -u -p
use
UPDATE system SET status = 1 WHERE name = 'block' OR name = 'user' OR name = 'node' OR name = 'filter';
exit

Then reload the installer page on which the error occurred and your installation wil continue.

We’ll demonstrate how to 1) add a profile box to a user profile and 2) post a message to the news feed.

After we’ve set up the application in the Developer App, we’ll start with some code to instantiate a facebook object with our unique API key and application secret. This object contains the api_client object with all the API methods we need. It also contains methods to retrieve some values we’ll need during the application session, like the user’s unique ID.

// the facebook client library
include_once 'facebook-platform/php/facebook.php';

// Get these from http://developers.facebook.com
$api_key = '<your key goes here>';
$secret  = '<your app secret goes here>';

// We may want to use this URL later
$app_url = "http://apps.facebook.com/helfrichabsinthe/";

$facebook = new Facebook($api_key, $secret);
$facebook->require_frame();
$user = $facebook->require_login();

We’ll define a variable that contains the FBML code for our profile box. Actually, we’ll need two boxes. The “narrow box” is the one the users will be prompted to add to their profile. A user will be able to move it to the Boxes tab. This will be our “wide box.” There used to be a third box for mobile devices but it’s deprecated by now. For the sake of simplicity we’ll fill these boxes with our initial box code. We can modify this later.

The FBML code is passed by reference so we’ll be able to update it later without having to republish.

$Box = "<a href=\"{$app_url}\">I love Helfrich Absinthe.</a><br/>
<img src=\"http://www.helfrichdranken.nl/eshop/images/helfrich_verte.jpg\"
border=\"0\" height=\"120\" width=\"120\"><br/>
<a href=\"http://www.helfrichabsinthe.com/\" target=\"_blank\">
www.helfrichabsinthe.com</a>";

$facebook->api_client->call_method('facebook.Fbml.setRefHandle',
array( 'handle' => 'BoxHandle', 'fbml' => "$Box" ,) );
$NarrowBox = "<fb:ref handle=\"BoxHandle\" />";
$WideBox = $NarrowBox;

Now we have all we need to instantiate the profile box. Note that it will only be visible after the user has added it. NULL values are used for deprecated parameters.

$ret = $facebook->api_client->profile_setFBML(NULL, $user, $WideBox, NULL,
NULL, $NarrowBox); 

Next we create a simple FBML canvas for our application to present itself. It contains the button that allows users to actually add the box to their profile.

<div style="padding: 10px;">
  <h2>Thanks for loving Helfrich Absinthe. We love you too, <fb:name
firstnameonly="true" uid="<?=$user?>" useyou="false"/>!</h2><br/>
Please add us to your profile.<br/> <br/>
<fb:add-section-button section="profile" />
<br/>
</div>
<div style="padding: 10px;">
<img src="http://absintblog.be/wp-content/uploads/helfrich-verte-1.jpg">
</div>

Finally we want to prompt users to publish their action to the feed. There are several ways to do this, but most of them seem to be partially or fully deprecated. Facebook encourages the use of the FBJS function Facebook.streamPublish.

We won’t need templates to format the message. Instead we’ll pass a JSON object as a so-called attachment. We can also specify some “action links“. These are added as options to the line below our posting (after Comment, Like, etc.) and need to be passed as an array of JSON objects. It’s not as complicated as it probably sounds:

<script>
var attachment = {'caption':'{*actor*} loves Helfrich Absinthe.','description':
'Click the link below if you do too.','media':[{'type':'image','src':
'http://www.helfrichdranken.nl/eshop/images/helfrich_verte.jpg','href':
'http://www.helfrichabsinthe.com/'}]};
var actionlink = [{'text':'Click here if you do too.','href':
'http://apps.facebook.com/helfrichabsinthe/'}];
Facebook.streamPublish(’loves Helfrich Absinthe.’, attachment, actionlink);
</script>

Invoke as follows:

java -jar Dilute.jar

To create a desktop launcher provide the full path to the jar file.

This tool shouldn’t be used for commercial purposes. Note that it doesn’t take the phenomenon of contraction into account.

Download: Dilute.jar

The script parses the <title> tags on the referred pages to name the links.

To install it copy the script file to your plugin directory. Activate the widget in WordPress under Plugins, add it under Design->Widgets and customize it.

These values can be edited:

• Title.
• URL list. This is a text field containing all URLs separated by spaces.
• The number of random links to display.

Download: linkroll.tgz

We worked around the problem by creating a boot CD that would load a kernel, recognize the drive and continue booting the root partion on it.

First install the package syslinux.

Create a working directory:

mkdir bootcd

Add isolinux.bin:

cp /usr/lib/syslinux/isolinux.bin bootcd

Copy the appropriate kernel and ramdisk images to bootcd/linux and bootcd/initrd.img respectively, e.g:

cp /boot/vmlinuz-2.6.22-14-generic bootcd/linux

cp /boot/initrd.img-2.6.22-14-generic bootcd/initrd.img

Create a file bootcd/isolinux.cfg containg a line that will point to your root partition, e.g. /dev/sda1:

DEFAULT linux initrd=initrd.img ro root=/dev/sda1

Create an iso image of the working directory:

mkisofs -o bootcd.iso -b isolinux.bin -c boot.cat -no-emul-boot -boot-load-size 4

 -boot-info-table -J -hide-rr-moved -R bootcd/

Burn the image to CD.

Boot your system.

To get the Pinnacle USB2 device working you’ll need the kernel module for the em28xx chipset. This module is not included in the Suse distribution, so obtain the video4linux package v4l-dvb from linuxtv.org.

Note: You do not need the usbvision package. It only supports USB1.

The sources of your current kernel need to be installed in order to compile the v4l package. Simply get the kernel sources with Yast. Unpack the v4l package, change to its directory and build the modules:

make
make install

Check for the presence of a running ivtv_tveeprom module:

lsmod | grep ivtv_tveeprom

If it is present remove it from the kernel:

modprobe -r ivtv_tveeprom

Insert the appropriate v4l-dvl modules:

modprobe tveeprom
modprobe tuner
modprobe em28xx

If module insertion fails, check out dmesg to find out what goes wrong, e.g.:

dmesg | grep em28
em28xx: module not supported by Novell, setting U taint flag.
em28xx: disagrees about version of symbol tveeprom_hauppauge_analog
em28xx: Unknown symbol tveeprom_hauppauge_analog

The easiest way to solve this problem is to reboot your system after the installation of the v4l modules.

Redirect the DSP sound device with SoX:

sox -t ossdsp -r 48000 -b -c 2 /dev/dsp1 -t ossdsp /dev/dsp

Plug in the PCTV USB2 device.

Functionality has been tested with the TV viewers mplayer and tvtime (PAL modus). These packages are included in the Suse distribution.

Consult the em28xx discussion in the video4linux wiki$ if you experience any problems.
