The password of the user with the lowest ID (typically an administrator) can be reset by an unauthorized user in Joomla 1.5.x installations prior version 1.5.6 because of a bug in the password remind functionality.

All 1.5.x installations prior to and including 1.5.5 are affected

The Joomla developer team advises to upgrade to 1.5.6 (or patch the /components/com_user/models/reset.php file with the code below).

After global $mainframe; on line 113 of reset.php, add:

if(strlen($token) != 32) {
    $this->setError(JText::_('INVALID_TOKEN'));
    return false;
}

.. the Dark Side of the Force are they ..
more to say?

Edit wp-config.php and add
define('ENABLE_CACHE', true);

Create the directory cache in the folder wp-content/ (take care it’s writeable!)

If you want to take control about expiration time, you can do this including these lines in wp-config.php:
define('CACHE_EXPIRATION_TIME', 900);

That’s all : )
The next time, your blog is being visted, the pages will be cached..
B.t.w.: You can empty the cache directory every time you want (in case of trouble, etc..).

Update (!):
The file-based caching mechanism has been removed from the WordPress 2.5 code. Detailed infos at neosmart.net.

If not already done, enable “Override” for Options and FileInfo in your apache configuration (needed for mod_rewrite and symlinks):

<Directory "/srv/www/htdocs/##user##/html">
AllowOverride Options FileInfo
</Directory>

Move the default htaccess.txt to .htaccess and activate SEF in your Joomla config. That’s all : )

If you’ve downloaded release 2.1.1 within the last 4 days, your version may include dangerous code. You should upgrade all your files to v.2.1.2 immediately!

According to the developers of wordpress, a server has been hacked and the download-package was replaced with a version that included some backdoors to implement php code.

If you want to convert a flash stream into a more comfortable format, that can be saved on your local disc and be played by most software/hardware, here’s a short guide:

Save your prefered video (from i.e. YouTube, MyVideo, etc.) with KeepVid.

When FFmpeg is installed, the conversion in Linux is quite simple:
ffmpeg -i input.flv -ab 128 -ar 44100 -b 900 \
-s 640x480 output.mpg

-b = videobitrate
-ab = audiobitrate
-ar = audiosamplerate (Hz)
-s = framesize width * height

I get more and more requests for several special Apache settings, like: “please turn off Safe-Mode” regarding Joomla. I keep questioning myself what is the big advantage comparing Joomla to Wordpress or any other CMS. Any suggestion is appreciated!
