Generate a map of your live streaming viewers by placing of your viewer’s IP into a file and then using IPInfo’s map tool.
vim ipList
54.0.0.1
54.0.0.2
54.0.0.3 |
vim ipList 54.0.0.1 54.0.0.2 54.0.0.3
To plot the IPs on a map, pipe them to IPinfo.io.
cat ipList | curl -XPOST --data-binary @- "ipinfo.io/map?cli=1" |
cat ipList | curl -XPOST --data-binary @- "ipinfo.io/map?cli=1"
The result is a URL of the map.

If you’re trying to access GCS (Google Cloud Storage) and you’re getting “Your credentials are invalid. Please run gcloud auth login”, you most likely have a previous key stored in the ~/.boto file. This happens if you previously configured gsutil with your own credentials, then switched over to Google SDK mode. To fix the invalid credentials, edit the ~/.boto file and comment out the auth key.
vim ~/.boto |
vim ~/.boto
Comment out.
#gs_oauth2_refresh_token = <token redacted> |
#gs_oauth2_refresh_token = <token redacted>
Rerun the gsutil ls command. It should work.

If you get a WordPress “There has been a critical error on your website” error, you probably have an issue with a theme or plugin. The quickest way to troubleshoot is to rename the plugins directory since there’s no way to login. This technically disables all plugins. Rename it back to plugins and enable each plugin one by one.
Disable all plugins.
mv plugins plugins-backup |
mv plugins plugins-backup
Login and restore the plugins directory.
mv plugins-backup plugins |
mv plugins-backup plugins
Enable each plugin one by one and check if the site is broken.
