New Ubuntu System Setup

• Steps
• Optional
• For Open Robotics

Steps

This is a brief series of steps that I repeat when setting up a new Ubuntu 20.04 machine to work on.

0. Set the keyboard to Dvorak
1. All updates and upgrades
2. Adjust settings
   1. In Displays, enable night light
   2. In Appearance, change to dark
   3. In Power, set blank screen to "Never"
3. Setup core desktop programs
   1. Install the following from the Ubuntu Software app
      1. VS Code (code)
      2. Brave
   2. Set VS Code and Brave to be the only apps pinned
   3. Setup sync with Brave
   4. Login to password manager
   5. Connect VS Code to Github to sync settings
4. Run the following in terminal

   sudo apt install -y curl git vim dconf-editor

5. Switch capslock and escape (source)
   1. Run dconf-editor
   2. Go to org >> gnome >> desktop >> input-sources
   3. Set xkb-options to ['caps:swapescape']
6. Install Deno

   # https://deno.land/
   curl -fsSL https://deno.land/x/install/install.sh | sh
   # Test with
   deno run https://deno.land/std/examples/welcome.ts

7. Install Docker

   # https://get.docker.com/
   $ curl -fsSL https://get.docker.com | sh
   # Setup docker to run without sudo
   # https://docs.docker.com/engine/install/linux-postinstall/
   sudo groupadd docker
   sudo usermod -aG docker $USER
   newgrp docker
   # Test with
   docker run hello-world

Optional

1. Setup VIM
2. Setup Bashrc

   alias gb='git branch -a'
   alias gcb='git checkout -b'
   alias gd='git diff HEAD'
   alias gg='git gui'
   alias gl='git log --pretty=oneline --graph'
   alias gs='git status'

3. Setup SSH key and connect to Github
4. Setup Github's CLI

   # https://github.com/cli/cli/blob/trunk/docs/install_linux.md
   curl -fsSL https://cli.github.com/packages/githubcli-archive-keyring.gpg | sudo dd of=/usr/share/keyrings/githubcli-archive-keyring.gpg
   echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/githubcli-archive-keyring.gpg] https://cli.github.com/packages stable main" | sudo tee /etc/apt/sources.list.d/github-cli.list > /dev/null
   sudo apt update
   sudo apt install gh
   gh auth login

5. Git config

   git config --global user.email "audrow@hey.com"
   git config --global user.name "Audrow Nash"

For Open Robotics

• Add the following to your bashrc:

  alias gb='git branch -a'
  alias gcb='git checkout -b'
  alias gd='git diff HEAD'
  alias gg='git gui'
  alias gl='git log --pretty=oneline --graph'
  alias gs='git status'
  
  alias rh='cd $ROS_PATH'
  alias cdrr='cd /root/.local/share/rr/'
  alias cb='rh; colcon build --symlink-install'
  alias cbd='cb --cmake-args -DCMAKE_BUILD_TYPE=Debug'
  alias cbs='cb --packages-select'
  alias cbds='cbd --packages-select'
  alias cbu='cb --packages-up-to'
  alias cbdu='cbd --packages-up-to'
  alias code='code --user-data-dir /root/.visual_code/'
  alias ct='colcon test'
  alias ctl='ct --mixin linters-only'
  alias cts='ct --packages-select'
  alias ctls='ctl --packages-select'
  alias ctr='colcon test-result --verbose'
  alias ctra='colcon test-result --verbose --all'
  alias ctrd='colcon test-result --delete'
  alias gdb1='gdb --eval-command run --batch'
  alias vcscheckout='vcs custom --git --args checkout'
  alias STRESS='stress -c $(nproc) -m $(nproc) -i $(nproc) -d $(nproc)'
  function repeat { while \$1; do \$2:; done; }
  function repeatg { while gdb1 \$1; do \$2:; done; }
  function cbts { cbs $1 && cts $1 && ctr; }

• Adding these to your bashrc if working with VIPER

  function kill_gazebo() {
  #killall gzserver
  pkill -9 gzserver > /dev/null 2>&1
  pkill -9 gzclient > /dev/null 2>&1
  pkill -9 python3
  }
  function kill_yamcs() {
  pkill -f "java.*YamcsServer" > /dev/null 2>&1
  }
  function kill_ros2() {
  ps -ef | grep 'rgsw_ws' | grep -v grep | awk '{print $2}' | xargs -r kill -9
  ps -ef | grep 'vipersim_ws' | grep -v grep | awk '{print $2}' | xargs -r kill -9
  ps -ef | grep 'ros2' | grep -v grep | awk '{print $2}' | xargs -r kill -9
  }
  function kill_rfsw() {
  pkill -9 qemu-system-ppc
  ps -ef | grep 'core-cpu' | grep -v grep | awk '{print $2}' | xargs -r kill -9
  }
  function kill_viper() {
  kill_gazebo
  kill_yamcs
  kill_ros2
  kill_rfsw
  }
