If we look at the output of the ` lifecycle_talker ` , we notice that nothing seems to happen. This makes sense, since every node starts as ` unconfigured ` . The lifecycle_talker is not configured yet and in our example, no publishers and timers are created yet. The same behavior can be seen for the ` lifecycle_listen...
