Installing NetBeans without JDK 1.5+
Get the current JDK flavor you want, and you will need to start the program the following way:
C:
CD "C:\Java\NetBeans 6.7\NetBeans 6.7\bin"
netbeans.exe --jdkhome "C:\Java\jdk1.6.0_14"
The --jdkhome switch is the "special sauce" that makes it work.

Manual removal of Firefox extension, if normal removal fails
- Open the Firefox profiles folder, which normally located at %AppData%\Mozilla\Firefox\Profiles\xxxxxxxx.default\, where xxxxxx is a random string. User should pick the profile folder (if inside Profiles folder there are multiple sub-folders) that are active, i.e. profile for user account to uninstall the extension.
- Open the extensions folder inside the profile folder.
- Each folder here inside the "extensions" folder corresponds to an extension. Some folders may have readable name that resembles the plugin, extension or toolbar, and can be easily recognized. Often the names of the folders are obscured. To identify which extension or plug-in the folder is representing, go to each folder and perform the following steps:
- Use a text editor to open the install.rdf file inside it.
- Search for the following text: em:name
- Locate the folder with install.rdf file with the name after the "em:name" corresponding to the extension intends to remove or delete.
- Delete the whole folder for the extension.
Force WordPress to use SSL (HTTPS) for Login
To easily enable (and enforce) administration over SSL, there are two constants that you can define in your blog's wp-config.php file.
To Force SSL Logins
The constant FORCE_SSL_LOGIN can be set to true to force all logins to happen over SSL.
define('FORCE_SSL_LOGIN', true);
To Force SSL Logins and SSL Admin Access
The constant FORCE_SSL_ADMIN can be set to true to force all logins and all admin sessions to happen over SSL.
define('FORCE_SSL_ADMIN', true);
Which Should I Use?
FORCE_SSL_LOGIN is for when you want to secure logins so that passwords are not sent in the clear, but you still want to allow non-SSL admin sessions (since SSL can be slow).
FORCE_SSL_ADMIN is for when you want to secure logins and the admin area so that both passwords and cookies are never sent in the clear. This is the most secure option.
