Fixing Magento error "[unknown object].fireEvent()"
error: error in [unknown object].fireEvent():
event name: address_country_changed
error message: zipElement.up(...).down(...) is undefined

Regarding to this forum post, this has something to do with defining the zip code as not required filed in the database.

Steve Ballmer is Going to Retire
Microsoft CEO Steve Ballmer is going to retire within the next 12 months, the company announced early Friday. This will happen when a replacement is found.
Ballmer said: "There is never a perfect time for this type of transition, but now is the right time. We have embarked on a new strategy with a new organization and we have an amazing Senior Leadership Team. My original thoughts on timing would have had my retirement happen in the middle of our company’s transformation to a devices and services company. We need a CEO who will be here longer term for this new direction.”
Microsoft also announced it has appointed a special committee to head up the process of finding a replacement for Ballmer. The company's stock shot up by nearly 9% in pre-market trading following the news.
This news about Ballmer retirement come barely one month after Ballmer led a massive reorganization of the company in an attempt to bring all divisions under one unified vision.
How to create .zip files in Ubuntu Linux
On a Windows machine, creating a zip archive is very easy: you can right-click on a file or folder, open "Send" menu and then click "Compressed ZIP folder". Or, you can use more advanced archivers like 7-Zip archiver, or WinRAR archiver. Their interface is quite self-explanatory, and easy to use.
But sometimes, you need to create a .zip archive on a Linux machine. This is required when doing a website backup, before downloading large number of files and other tasks.
To create .zip files in Ubuntu Linux, in the command line type:
zip -r archive-name directory-name
This will create archive named "archive-name.zip" and add directory-name directory to it, including all subdirectories.
For example, to create an archive of directory /home/user/www, issue the following command:
zip -r ./www1.zip /home/user/www
This will create www1.zip file in the current directory and add the contents of folder /home/user/www including all subdirectories to this archive.

Fixing MMC cannot open the file COMPMGMT.MSC error
The error appears when you attempt to open Computer Management. The following message appears:
MMC cannot open the file C:\WINDOWS\SYSTEM32\COMPMGMT.MSC.
This may be because the file does not exist, is not an MMC console, or was created by a later version of MMC. This may also be because you do not have sufficient access rights to the file.
The mentioned file exists in the c:\windows\system32 directory and the user is logged on with Administator rights.
