This does require modifications of your code and generally is being used for positioning in customized site setups First off, you will need to place some code on your site.

SMF Using Nginx to enable special variables
I came up with this little trick while working with my SMF installs. I wanted to be able to present $db_show_debug to myself but not others. There are many ideas involved in this including waiting until we loaded enough of the user profile to check if they are a admin and then enabling it. However …
Mysterious Account Lockouts
TLDR: Use PsExec and run “cmdkey /list” on affected systems. Occurs from a combination of saved credentials, DFS/domain accessing when installing software.

Watchguard has two ways to upgrade the firmware. One is from the web UI and the other via Firebox System Manager. I prefer the System Manager, but when you download the firmware it runs an installer. This is leaving my programs list full of firmware update packages. Lots of clutter that Watchguard could easily fix …

Using a scheduled task to execute powershell.exe with a -file parameter, I was able to decline the “Preview of Monthly Quality …
Zabbix 3.0 on Ubuntu 16.04 with Percona
After upgrading to Ubuntu 16.04, I couldn’t get Zabbix to run and was receiving the following zabbix-server[3962]: /opt/sbin/zabbix_server: /usr/lib/libmysqlclient.so.18: version `libmysqlclient_18′ not found (required by /opt/sbin/zabbix_server) To fix this I needed to symlink the perconaclient library to the mysql client libraries that Zabbix was expecting. apt-get install libperconaserverclient18 ln -s /usr/lib/x86_64-linux-gnu/libperconaserverclient.so.18 /usr/lib/libmysqlclient.so.18 ln -s /usr/lib/x86_64-linux-gnu/libperconaserverclient_r.so.18 …
SMF 2.0 with PHP 7
SMF does not officially support running version 2.0.x with PHP 7.0. This is due to PHP removing the mysql library in favor of more secure MySQLi library.
