Element and attribute names must be in lower case
XHTML documents must use lower case for all HTML element and attribute names. This difference is necessary because XML is case-sensitive e.g. <li> and <LI> are different tags.

Sending Files from an Ubuntu PC to Another Device
The easiest way to send files from your PC to a Bluetooth device is to create a desktop shortcut onto which you can drag and drop files. Follow these steps to create the shortcut:

• Right-click the desktop, and click Create Launcher.
• In the Name field, type something like “Send file via Bluetooth”.
• In the Command field, type “gnome-obex-send”.
• You can also choose to give the new shortcut an appropriate icon. Click the No Icon button, and then type the following into the Path field: /usr/share/icons/gnome/48×48/stock/io/stock_bluetooth.png
• Click OK.

After you’ve created the icon, you can send files as follows:

• Drag and drop a file onto the launcher (icon) you just created.
• The Choose Bluetooth Device dialog box appears. Click Refresh to make the computer detect any nearby Bluetooth devices. This may take a minute or two. Remember that your device will need to be set to be “visible,” so that other Bluetooth devices can automatically detect it.
• Select the device to which you want to transfer the file, and then click OK.
• Check the device to see if the file transfer needs to be authorized. If the devices are paired, the transfer might take place automatically.

What you need:

• A crusty, old Oracle 8 database server (might also work with 8.x)
• An equally crusty, old version of ApacheFriends XAMPP 1.4.4
• A slightly less crusty, but almost as old Oracle 9i Database Release 2 Client
• Strongly Recommended - A fresh Windows XP virtual machine (VM)

Honestly, it isn’t really that hard once you know which version of the Oracle client to use. Here is a rundown of each Oracle Client:

• Oracle 8 - PHP complains
• Oracle 9 - The only one that none of the components bitch about
• Oracle 10 - Oracle complains
• Oracle 11 - Oracle complains

Now for the steps:

• Fire up your Windows XP VM (Be sure to use “Bridged”, not “NAT” if you are using VMWare)
• Install XAMPP
• Install Oracle 9i R2 Client using the default install location settings (Be sure to select the “Runtime” installation type). I canceled the “Oracle Net Configuration Assistant” because I am not set up for that.
• Reboot the computer to make sure the PHP _SERVER[”Path”] and _ENV[”Path”] variables get updated.
• Create a tnsnames.ora file in the folder “C:\oracle\ora92\network\ADMIN” and include an entry for the server you want to access. Obviously, modify the information below to match your connection settings, here is an example: db=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=PROTOCOL=TCP)(Host=hostname)(Port=1521)))(CONNECT_DATA=(SID=db)))
• Open the Command Prompt and type: “tnsping db” If you cannot use the tnsping command, make sure your Oracle 9 installation is listed at the beginning of the “Path” variable for Windows (Contol Panel > System > Environment Variables). Ensure you have something like “C:\oracle\ora92\bin”. Don’t proceed until tnsping returns something to the effect of “Blah Blah…OK (10 msec)”. If you get “TNS-03505: Failed to resolve name”, check your tnsnames.ora file for errors.
• Now you need to edit the php.ini file. Make sure the line starting with extension_dir has the correct path to your extension directory. For example: extension_dir = C:\xampp\php\extensions\
• Also in the php.ini file,uncomment the line “extension=php_oci8.dll” (delete the semi-colon) to activate the Oracle extension in PHP. You might have multiple php.ini files on your system, just make sure you update all of them.
• Start the Apache web server. If you get errors on start up, you might have missed a step.
• Use the phpinfo link on your local ApacheFriends start page or create a phpinfo() script of your own to display the current php configuration. If Oracle is enabled you should see a section like this:
  oci8
  OCI8 Support enabled
  Revision $Revision: 1.183.2.12 $
• The very last trick is that you have to use the deprecated php4 oci commands rather than the shiny new php5 ones. From what I have seen so far oci* commands work, oci_* commands aren’t compatible with php4.

Try running this first to make sure everything is working:

<?php
$conn = OCILogon("username", "password", "db");
if ($conn){
print "Connection Established. ";
}
OCILogoff($conn);
print "Connection Closed.";
?>

Here is a fancier example which outputs the results of a select statement into an html table:

<?php
$conn = OCILogon("username", "password", "db");
$sql = "<PUT A SELECT STATEMENT IN HERE>";
$stmt = OCIParse($conn, $sql);
OCIExecute($stmt);
$rows = OCIFetchstatement($stmt,$results);
$keys = array_keys($results);
$table = "<table>\n <TR>\n";
foreach($keys as $key)
{
$table .= " <TH>$key</TH>\n";
}
$table .= " </TR>\n";
for($i=0;$i<$rows;$i++)
{
$table .= " <TR>";
foreach($results as $spalte)
{
$data = $spalte[$i];
$table .= " <TD>$data</TD>";
}
$table .=" </TR>";
}
echo $table;
OCILogoff($conn);
?>

• Create a .htaccess file in your main wordpress folder (the same one as index.php)
• Make the .htaccess file writeable
  chmod 777 .htaccess
• Ensure mod-rewrite is enabled for Apache2 (/etc/apache2/mods-enabled). There should be a symlink to /etc/apache2/mods-available/rewrite.load. If not, create it.
  sudo a2enmod rewrite
• Restart Apache2
  sudo apache2ctl restart
• Login to your WordPress admin. Go to “Options” > “Permalinks” > select the one you want. (I chose “Date and name based” e.g. “http://www.example.com/2007/11/07/sample-post/”)
• Reset the .htaccess file permissions
  chmod 644 .htaccess

Well the folks at MySQL would like you to consider a visual database design tool called MySQL Workbench. The first release candidate showed up on March 17, 2008 and from what I have seen so far, it is the best tool available for designing MySQL databases. There are two editions Community Edition (OSS) and Standard Edition. I have been using the Community Edition for a project I am working on now and it is a great upgrade to MS Visio.
