Note for Dmitri/David: the Virtualbox/Cosmos instructions just document what you guys already went through. This doesn't require a second VM or anything.

Virtualbox

• Download Ubuntu 18.04 ISO
• Create new linux 64-bit VM in Virtualbox
• Set memory to 4096 MB
• Do “minimal installation”
• Accept all other defaults
• Increase VM video memory to max
• sudo apt install gcc perl make
• Devices -> Insert Guest Additions CD Image (to enable bidirectional clipboard)
• Reboot

Cosmos

• sudo apt update
• sudo apt dist-upgrade
• reboot
• sudo apt install git ruby-dev rbenv curl postgresql libpq-dev
• sudo gem install rake bundler ruby-termios
• bash <(\curl -sSL https://raw.githubusercontent.com/BallAerospace/COSMOS/master/vendor/installers/linux_mac/INSTALL_COSMOS.sh)
• Install dependencies using Sudo (s)
• Accept all other defaults
• Once the script finishes running successfully, you’ll see cosmos!
• Quit
• Close terminal
• Open new terminal (should now be using rbenv ruby)
• cd cosmosdemo
• bundle install
• ruby Launcher
• It should launch
• Congrats! You can now run cosmos at will
• Quit Cosmos

DART

• based on: https://cosmosrb.com/docs/dart_install/
• vi config/system/system.txt
• Paste in the following lines:

 DECLARE_TARGET DART
 LISTEN_HOST DART_STREAM 0.0.0.0 # 127.0.0.1 is more secure if you don't need external connections
 LISTEN_HOST DART_DECOM 0.0.0.0 # 127.0.0.1 is more secure if you don't need external connections
 CONNECT_HOST DART_STREAM 127.0.0.1
 CONNECT_HOST DART_DECOM 127.0.0.1
 PORT DART_STREAM 8777
 PORT DART_DECOM 8779
 PATH DART_DATA ./outputs/dart/data
 PATH DART_LOGS ./outputs/dart/logs

• vi Gemfile
• uncomment this line: instance_eval File.read(File.join(__dir__, 'config/dart/Gemfile'))
• add this to your .bashrc:

export DART_USERNAME='dart'
export DART_PASSWORD='dart'
export DART_TEST_DB='darttest'
export DART_DB='dart'

• close the terminal and open a new one (to get those new environment variables)
• bundle install
• now start on DART install step 6 (except use sudo -u postgres psql to connect)
• https://cosmosrb.com/docs/dart_install/
• do this extra step 10.5:
• sudo vi /etc/postgresql/10/main/pg_hba.conf
• add this line: in the "PUT YOUR ACTUAL CONFIGURATION HERE" section

local   all             dart	                                md5

• sudo systemctl restart postgresql
