Why does this seem to apply to so many things these days? It's not just learning a programming language.
Thanksgiving morning, I received a Teams message from an offshore resource asking about a message she received when deploying a Power BI report. For starters, she advertised herself as an experienced Power BI developer. The setting she missed is pretty basic. A Google search turned up the explanation on the first hit.
An experienced developer complained to me that until SQL has a date, and a time, datatype, it will never be a very good database. This person has been writing code since the 90's. When I told him that date and time types have been in there for almost 15 years, he was astounded. His response? Why didn't they (me) tell anyone?
