First, try reading the error message, episode 3: Even programmers see error messages without reading them
As we all know, users don’t read error messages.
And, sad to say, this behavior extends to the group of people
you would think pay the most attention to error messages,
namely, programmers, who are the people who cause your computer to
display the error messages!
Today’s example comes from an internal
programmer’s tool which I will call
I’m trying to back out an update I made to record 19 of our table
(which was entered as transaction 512),
but I can’t get it to work:C:\> q backout 512 Transaction opened for record 19 - must reconcile backout C:\> q commit all Transaction 520 created for 1 record Committing transaction 520 Record 19 - must reconcile backout Unreconciled changes pending - use 'q reconcile' to resolve Commit failed -- fix problems above and then use 'q commit 520'
What is the problem here, and how do I fix it?
The transaction couldn’t be backed out because somebody else
made a change to record 19 since your original erroneous update,
and the system wants you to reconcile this conflict.
But that’s beside the point.
The point is that the user here merely saw that there was an error
and didn’t actually read any of the error messages.
There were four error messages, and every single one told him
what he needed to do!
C:\> q backout 512 Transaction opened for record 19 -C:\> q commit all Transaction 520 created for 1 record Committing transaction 520 Record 19 - Unreconciled changes pending - Commit failed --
