How to Enable PHP Inside HTML Pages

php code can be embedded within html pages within the tags:

<?php echo "my php code"; ?>

However, and depending on the server that you are using, this must be enabled. On apache2, you can edit the .htaccess file to include:

AddType application/x-httpd-php .htm .html

I added this line to the .htaccess on my website's root directory.

Voila!

Picasa Installation Error on Ubuntu

So Picasa has failed to install on my Ubuntu box. The caveat is that it also prevented me to install any other packages and gave the following error whenever i tried to install something:

ubuntu previous installation hasn't been completed

I suspected it was Picasa, but to verify, I opened up a terminal and typed the following:

sudo apt-get -f install

and I got the following error message:

The package Picasa needs to be reinstalled, but I can’t find an archive for it.

The solution to this is to cleanup the incorrectly installed package (Picasa or else) via the following:

dpkg --remove --force-remove-reinstreq picasa

That solved the problem for me. I haven't tried reinstalling Picasa though.
