Installing Golang

# As of Go 1.6 (February 2016), an official ARMv6 package is available for download. So, if your Raspberry Pi has ARMv6 or v7 (see cat /proc/cpuinfo | grep ARM), then just do something like:

wget https://storage.googleapis.com/golang/go1.6.2.linux-armv6l.tar.gz 
sudo tar -xzf go1.6.2.linux-armv6l.tar.gz -C /usr/local
sudo chgrp -R staff /usr/local/go
export GOROOT=/usr/local/go
export PATH="$PATH:$GOROOT/bin"

Run raspberry pi in virtual machine

brew install qemu
# First, create a folder for your VMs and move the image in
sudo mkdir ~/qemu/
mv ~/Downloads/IMAGE.iso ~/qemu/
cd ~/qemu
# Now let’s launch the image in qemu with the following command:
qemu-system-x86_64 -hda IMAGE.iso -m 1024 -net nic -net user
