No matter HOW hard we try, programmers still design error messages that are meaningless to all but the coder. This from a payment machine on one of the new TTC streetcars. There is enough to know that it is a Critical error, of type 19? Come on people, design error messages that are meaningful! To top it off it says that it is “reconnecting” to the backend… but there is NO STATUS to show anything. Usability 101!
