When postfix install prompt shows up (Choose internet site configuration and use the computers name)

Edit postfix config file

sudo vim /etc/postfix/main.cf

Set inet_interfaces to be loopback-only

inet_interfaces = loopback-only

Restart postfix

sudo service postfix restart

Git

Set name and email for commits

git config --global user.name "Your Name"
git config --global user.email YOUR@EMAIL.com

Generate an SSH keypair

ssh-keygen -t rsa -C "YOUR@EMAIL.com"

Copy the output of this command and paste into github SSH key settings.

cat ~/.ssh/id_rsa.pub

Check to make sure SSH to github works with your key

ssh -T git@github.com

PostgreSQL

Set postgres user password

sudo -u postgres createuser myuser -s

sudo -u postgres psql
postgres=# \password myuser

zsh and oh-my-zsh

sudo apt-get install zsh fonts-powerline
chsh -s $(which zsh)
# logout and back in
sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

asdf version manager

git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.7.8
