Taken from here.

gnome-shell-frippery

 

An unofficial extension pack providing GNOME2 like features for GNOME3.

Similiar to windows command ipconfig /release in Arch Linux is ip link set eth0 down, and ipconfig /renew it would be ip link set eth0 up

For 64 bit procesors first you must to edit /etc/rc.conf like:

[multilib]
Include = /etc/pacman.d/mirrorlist

upgrade your system:

# pacman -Syyu

and install gcc-multilib and its dependencies

pacman -S gcc-multilib gcc-libs-multilib binutils-multilib libtool-multilib lib32-glibc
