When setting up a site in Joomla for multiple languages JoomFish is the tool for you. But there are some things in Joomla that JoomFish can’t handle, like the slogan for example. This is one way of making a language dependent slogan.

1. Create a file called en-GB.tpl_your_template_name_here.ini in language/en-GB (replace "your_template_name_here" with the actual name of your template).
2. Insert a line like this in the file you just created:
   SLOGAN=Your slogan in english here
3. Repeat the above steps for all languages you are supporting in your site, replacing en-GB in the directory and file name with the language codes for each language and the slogan in the corresponding language, for example sv-SE/sv-SE.tpl_your_template_name_here.ini for Swedish.
4. Edit your template’s index.php file and find the line that outputs the slogan. It will look something like this:
   <?php echo $slogan;?>
   or
   <?php echo $this->params->get('siteSlogan'); ?>
5. Replace the line with this:
   <?php echo JText::_('Slogan'); ?>

This will give you slogans displayed in different languages but to change the slogan, the above ini-files must be edited (the template slogan parameter will no longer have effect). 

The same method can be used if you want to have different logos displayed for different languages.

In Asterisk it is possible to upload .wav or .mp3 files to be used as music-on-hold (MOH). Another option is to use streaming audio but using a stream from a Shoutcast server requires some hands on.

This is how I did the setup for AsteriskNow 1.7 with FreePBX 2.9.

First of all you will need mpg123 from www.mpg123.de to get the Shoutcast stream from the Shoutcast server.
If you already have gcc on your system you can skip the first step.

yum install gcc
wget http://downloads.sourceforge.net/project/mpg123/mpg123/1.13.4/mpg123-1.13.4.tar.bz2
bunzip2 mpg123-1.13.4.tar.bz2
tar xvf mpg123-1.13.4.tar
cd mpg123-1.13.4
./configure
make
make install

Login to admin of your AsteriskNow / FreePBX server and go to Setup -> Music On Hold. Click on Add Streaming Category. Enter the following: 

Category Name:   radio
Application:     /usr/local/bin/mpg123 -q -s -r 8000 -f 8192 -b 2048 --mono http://192.168.1.2:8000
Optional Format: mp3

Most Shoutcast streams are sampled at 44.100 kHz or 22.050 kHz in stereo. In order to use a stream for MOH in Asterisk it must be converted to 8 kHz mono, hence the parameters -r 8000 -f 8192 and –mono.

The IP-address 192.168.1.2 and port 8000 in the example should be replaced by the real ip-adress (or hostname) and the port number of the Shoutcast server you want to stream from.

In order to test the streaming music-on-hold, the easiest way is to set up a dummy extension (extension 446 in this example).
Edit extensions_custom.conf and add the lines below: 

nano -w /etc/asterisk/extensions_custom.conf

exten => 466,1,Answer
exten => 466,2,SetMusicOnHold(radio)
exten => 466,3,MusicOnHold()
exten => 466,4,Hangup

Save it by pressing CTRL-X and respond Y.

Now login to admin of your AsteriskNow / FreePBX server and go to Tools -> Custom Extensions. Click on Add Custom Extension. Enter the following: 

Custom Extension: 466
Description:      radio
Notes


And then click Submit Changes.

Don’t forget to click the orange Submit Configuration Changes in the top of the screen.

If all works as planned you will hear the streaming Shoutcast station when you dial extension 466.
 

 Suddenly my VMware vSphere client version 4.0.0 started to crash when I try to upload a file to the datastore. This happens on both my Windows Vista and XP boxes running the VMware vSphere client.

The problem is similar to the one described in this KB article concering Windows 7 clients. However, the solution is the same. The VMware vSphere client does not crash if it is started by right clicking and runing it as administrator.

If you get the error message "An error occurred while updating object. lang ()" when updating a language in PrestaShop, this is caused when the system doesn’t have permissions to write in the .htaccess-file in your root directory.

If the file does not exist, just create an empty .htaccess-file and make sure it is writeable by the user running the webserver process, for example by issuing: 

chmod 666 .htaccess

 When moving a PrestaShop version 1.4 webshop to a new domain name (from a development server to a live site for example) you must do the following: 

1. Make sure all directories are writeable according to the PrestaShop installation instructions.
   Don’t forget that the files in config directory must be writeable as well as the entire cache directory structure. All files and directories in tools/smarty/compile, tools/smarty/cache, tools/smarty_v2/cache and smarty_v2/compile must also be writeable.
   Internal server error 500 is a sign that these directories or files are not writeable.
2. Update the file config/settings.php regarding PS base URI (if that will change) and the database settings.
3. After importing the database on the new server use a tool like phpMyAdmin to access the database.
4. Login to the Back Office of your shop on the new domain and go to Settings -> SEO & URLS and update the domain name for the shop (two fields). If this is not successful use the steps 5-7, otherwise go to step 8.
5. Find a table named ps_configuration.
6. Find the records PS_SHOP_DOMAIN and PS_SHOP_DOMAIN_SSL
7. Update the values with your new domain name. You should enter just the domain name, no leading http:// or trailing path to subirectories (if your shop is located in a subdirectory, that should be entered in the PS base URI in step 1).
8. If you use .htaccess and robots.txt files, go to Tools -> Generators and regenerate them.

The PHP flock() function is good when the file locking method is used the same way by all programs that will lock the file.

However, you can’t check if any process in the system is actually using the file or not. If you for example are monitoring an incoming ftp folder, you don’t want to start processing a file until the file is completely tranferred (i.e. wait until the ftp daemon is no longer having the file open).

The following code illustrates how the command lsof can be used for the purpose: 

<?php
$filename = "locktest.txt";
$directory = ".";
while (1) {
        $result = exec("lsof +D $directory | grep -c -i $filename");
        if ($result == "0") {
                echo "$directory/$filename is NOT open ($result)\n";
        } else {
                echo "$directory/$filename IS OPEN ($result)\n";
        }
        sleep(1);
};
?>

The Ktools PhotoStore software (www.ktools.net) automatically generates thumbnails, sample and large images with watermarks of the images in the database. If you change the settings regarding the image sizes only newly added images will get the new sizes.

The following simple script regenerates / resizes the thumbnails, sample and large images from the original images. It runs in batch mode, i.e it will work on every image you have in your stock_photos folder. It will overwrite your current i_, s_ and m_-versions of your images without warning. The sizes is set in the script (it does not read the current settings in the manager).

On a PrestaShop 1.3.2.3 installation I purchased the One Page Checkout 1.2.2 and installed it. After that I got the following error message when trying to add a product to the basket in the shop front end:

TECHNICAL ERROR: unable to add the product.

Details:
Error thrown: [object XMLHttpRequest]
Text status: parserror

Solution: The reason is the web server is running in SAFE MODE and the user owning all the PrestaShop files is the FTP user I use to upload the shop. When installing the One Page Checkout module it will be owned by the user running the web server process (in my case www-data:www-data). In SAFE MODE a php script is not allowed to execute a script owned by another user.

The solution is to set the owner of all the order-files in the PrestaShop directory to my FTP-user (including the files installed by the OPC module). In a shell this is simply done by the chmod command:

cd prestashop-installation-dir
chown -R my-user:my-group order*

(Replace prestashop-installation-dir with the real path where PrestaShop is installed and my-user:my-group to the userid:grouid owning the rest of the files in the Prestashop installation.)

When you try to install a plugin in WordPress and get an error message like this:

Warning: file_exists() [function.file-exists]: open_basedir restriction in effect. File(/tmp//google-integration-toolkit.tmp) is not within the allowed path(s): (/var/www/XXX/) in/var/www/XXX/web/wp-includes/functions.php on line 2140

Download failed. Could not create Temporary file.

This is happening when the server is running with SAFE MODE because WordPress will not be able to access paths outside it’s web root. Find out the full path to your web root on the server (a hint is in the error message you just saw). Create a temporary directory within your website path and add the following line.

Edit wp-config.php and add:

define(‘WP_TEMP_DIR’, ‘/var/www/XXX/tmp’);

(Replace /var/www/XXX/tmp with the full path to your temporary directory.)

When writing a post in WordPress, and you press Upload/Insert buttons to insert images, video, music or other media you can run into a problem where a popup displaying “Are you sure you want to do this?” is showing instead of the normal insert screen. The problem is described here. As mentioned in the posts, it is caused by some plugin. This can be hard to guess as the plugin in question might have nothing to do with writing and posting articles.

I ran into this problem using the latest WordPress 3.0.1. The plugin that was causing trouble for me was WP-ContactForm. By disabling it, it was possible to insert images in the posts again.

If you experience this problem, try disabling all plugins. If inserting images now works, try enabling the plugins one by one to figure out which one is causing the trouble.
