                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 sommelier@0.service and sommelier-x@0.service show a failed status, the following worked for me:
sudo ln -s /opt/google/cros-containers/bin/sommelier.elf /usr/bin/

    Got Retweets?

Even though Twitter's statuses/retweets API endpoint is limited to the last
100 retweets it is possible to use the
search/tweets
endpoint to search for the retweets using the text of the tweet. Caveat: This is only possible for tweets that have happened in the last 7 days, which is furthest back Twitter allow you to search for tweets in.
For example here is how you can get the retweets for this
tweet and analyze the users in a spreadsheet.
