Occasionally when running Firefox on OS X with the Mac version of roaming profiles the lock file Firefox creates does not get deleted resulting in an error which states that Firefox is already running and needs to be closed.
Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.
To fix this delete the .parentlock file found under the users profile on the server in OS X or on the local machine for windows.
Mozilla has a page dedicated to the location of the user profile.

Got some sensitive information and want your users to be forced into an SSL connection. Here's a quick and easy little code snippet you can put at the top of the page to secure.
if ($_SERVER['HTTPS'] == 'off') {
$header_string = "Location:https://".$_SERVER['SERVER_NAME'].$_SERVER['PHP_SELF'];
header ($header_string); // Redirect to SSL connection
exit; // Kill this script
}

Should you ever need to force an update to McAfee Anti-Virus, this script will copy the latest SuperDAT update from a local server and initiate a forced silent installation. After the SDAT is executed it uses a WMI query to search for the process. Once the process has terminated it will clean up after itself.
Be sure to change the path to your server in the Copy section.
Enjoy!

At work today there was a bit of debate as to which compression method was best. I personally did not have a preference in the discussion but my curiosity was ignited. I decided to do a little test to see which method was the best. I fired up 7Zip and Win Rar to duke it out. Here are the results, taken directly from a command window.
100 Power Point template files, these are pretty big files with images inside.
Powerpoint Tmpl 100 File(s) 7,481,344 bytes
4,454,809 Powerpoint Tmpl.7z
4,926,588 Powerpoint Tmpl.rar
4,948,264 Powerpoint Tmpl.zip
Best Compression: 7 Zip 59.55% of the original size.
Now how about plain old text files, I grabbed 100 RFCs and zipped them up.
rfc (text) 100 File(s) 5,515,893 bytes
898,401 rfc (text).7z
1,068,499 rfc (text).rar
1,345,080 rfc (text).zip
Best Compression: 7 Zip 16.29% of the original size.
Now what about a distributed setup file, it already has some files compressed in to it. Behold windows media player 11 beta installation. This should be interesting...
wmp11-windowsxp-x86-enu.exe 1 File 24,070,456 bytes
24,030,963 wmp11-windowsxp-x86-enu.zip
24,070,547 wmp11-windowsxp-x86-enu.rar
24,312,838 wmp11-windowsxp-x86-enu.7z
Best Compression: Zip 99.83% of the original size.
The verdict, just as it has always been the best compression method depends on what you are compressing. Based on this simple test 7Zip seems to be great for just about anything, unless you are packaging a bunch of setup files in which case the Zip method seems best.
What makes this whole comparison even better is 7Zip is licenced under the GNU LGPL, which makes it easy to afford. Right now development is moving along nicely as evidenced by the 3 release versions (4.23-4.42) posted on the 7zip home page in the last year.
