Sometimes you need to access Joomla libraries and/or data from an outside script. You may need to sync users with a 3PD application, or maybe you're developing a fresh application, but you're used to Joomla style  JTable database manipulation, and JRequest input filtering.

I just noticed upon launching a new domain powered by Joomla 1.5 that HTTP headers are designed to prevent caching and force the client (be it some crawler, robot, such as Googlebot, or a regular visitor's browser) to always request the page from the server.

This is of little use if your articles are not changing over time. Forcing the client to request from server is good for sitemaps, or pages with ever-changing hot news.

Here's a linux command line solution to remove all your phoca thumbnails so the system will generate them again:

cd /home/your_joomla_folder/images/phocagallery

find  -name "*phoca_thumb*" -print0|xargs -0 rm

And here's another Phoca gallery trick for global watermark files(i.e you will have global watermark files instead of having to copy watermark-large.png and watermark-medium.png into all gallery subfolders):

If you're experiencing this behavior on your Joomla 1.5 site and using the sh404sef extension, the solution is quite simple.

I was excited to see that Joomla 1.5 added template language strings and parameters support.

This lasted about 30 minutes until i had to implement a multiple select list in template config.

Here's a common scenario, which happens to be mine ;) : you have a template with several color variations(blue and green) or layout variations, and you'd like to assign a different color or layout to each menuitem in Joomla menus. This will require a multipleselect list so you can quickly choose which menus will render a blue page, and which ones will render a green page.

Here's how I managed to PXE boot TRK(Trinity Rescue disk) using free software tools and a Windows XP sp2 machine as the server.

As you already know, Joomla has a built-in PDF generator. The problem with PDF's is that sometimes Google places the PDFs in search results(SERPs) instead of the original Joomla HTML content article.
