General communication.

So many fields and topics are deeply related.  Computing devices are showing up everywhere, but they are used to solve problems we have always had.

I had a chance to observe a parent and child interact in a way that reminds me of poor user interfaces.

On (many days) that day,  The parent started talking to the child, and the child did not respond. The parent moved on to do something else.  The child did not do the task that was demanded, and the parent became angry.      It was like the parent used UDP to communicate a critical message, and the packet got lost.   The parent should have used something like TCP, where a message delivery confirmation is expected.


This reminds me of unix programs that don't report on success.   Maybe there is a way to provide a sub-channel communication that indicates success.

It could also be possible to remap cp, mv, mkdir, and other common programs to use Kio and kfile (from KDE) to give someone notifications when transfers are done.  A simpler way to do this could be to have these programs log actions, (and use trash folders)
