Add something along the lines
hint.hdac.0.disabled=1
to the /boot/loader.conf

hdac being hw you want to prevent from attaching to, 0 being its unit.

In directory ~/.gconf/desktop/gnome/peripherals/mouse

After you update your OS and you forgot about this little quirk

edit /usr/local/bin/compiz-manager and change line saying
INDIRECT="no"
to
INDIRECT="yes"

UPDATE (2014-11-15):
Apparently this also depends on nvidia driver, so I am trying to keep the list of those I know work correctly, and those I know don't work correctly.

Working: 331.67, 331.113
Not working: 340.46, 343.22 (works most of the time, but sometimes get crazy), 346.22 similar to 343.22

You can create SOCKS proxy using ssh by running

ssh -D port [email protected]

replace port with port number you want proxy to appear on your local machine, in web browser choose SOCKS for proxy type, localhost for proxy server and same port as port in command above.

Like this
grant all privileges on db.* to 'user'@'host' identified by 'password';

Execute ipconfig /flushdns on command prompt

Probably impossible to list all, but here are really harmful if you are moving it to other server:

1. Install /usr/ports/ports-mgmt/portaudit in order to receive vulnerability reports with daily security reports
2. Install /usr/ports/ports-mgmt/portupgrade in order to be able to update ports in easier way
3. When you need to upgrade ports
   • portsnap fetch
   • portsnap update (or portsnap extract if using portsnap for the first time)

a2enmod ssl

• openssl pkcs12 -in file.pfx -nocerts -out pk.pem
• openssl rsa -in pk.pem -out key.pem

To extract certificate:

• openssl pkcs12 -in file.pfx -clcerts -nokeys -out cert.pem
