System Design Cheatsheet

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

  1. Clarify and agree on the scope of the system
  • User cases (description of sequences of events that, taken together, lead to a system doing something useful)
    • Who is going to use it?
    • How are they going to use it?

Fix Crostini Wayland/X (sommelier) service

If you can't get X11 or Wayland GUI Linux apps to start anymore on Chrome OS, try the following.

In the Terminal app, this will show the status of your systemd user services/units:

systemctl --user

If [email protected] and [email protected] show a failed status, the following worked for me:

sudo ln -s /opt/google/cros-containers/bin/sommelier.elf /usr/bin/
