# Installing MongoDB 3.2

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927
echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list

# Installing PostgreSQL 9.5

sudo sh -c "echo 'deb http://apt.postgresql.org/pub/repos/apt/ xenial-pgdg main' > /etc/apt/sources.list.d/pgdg.list"
wget - quiet -O - http://apt.postgresql.org/pub/repos/apt/ACCC4CF8.asc | sudo apt-key add -

# The PostgreSQL installation doesn't setup a user for you, so you'll need to follow these steps to create a user with permission to create databases. Feel free to replace Chris with your username.

sudo -u postgres createuser chris -s

# If you would like to set a password for the user, you can do the following

sudo -u postgres psql
postgres=# \password chris

# Installing and Configuring Git

git config --global color.ui true
git config --global user.name "YOUR NAME"
git config --global user.email "YOUR@EMAIL.com"
ssh-keygen -t rsa -b 4096 -C "YOUR@EMAIL.com"

# The next step is to take the newly generated SSH key and add it to your GitHub account. You want to copy and paste the output of the following command and paste it here.
cat ~/.ssh/id_rsa.pub

# Once you've done this, you can check and see if it worked:
ssh -T git@github.com

# You should get a message like this:
# Hi excid3! You've successfully authenticated, but GitHub does not provide shell access.

# Installing sublime text

wget -qO - https://download.sublimetext.com/sublimehq-pub.gpg | sudo apt-key add -
echo "deb https://download.sublimetext.com/ apt/stable/" | sudo tee /etc/apt/sources.list.d/sublime-text.list
sudo apt-get update
sudo apt install sublime-text

# Installing and configuring Oh-my-zsh

sudo apt-get install zsh
sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

# And, to make zsh as the default shell:
chsh -s $(which zsh)
# without sudo should work.

# Finally, log out of your computer and log back in.

# Installing Deepin Desktop Environment in Ubuntu
# Deepin is an attractive, unique alternative to GNOME Shell, Cinnamon and other DEs. It will allow your ubuntu to look-like macOS.
