I'll never forget this Delphi anecdote. It can be applied to other tools, no doubt, but we were using Delphi at the time. Simply, we had a junior guy doing some work, and he wrote a Client/Server GUI using Delphi talking to SQL Server (I think, not germane). Anyway, it was all done, shipped off the client, everyone essentially happy. I asked him how the project went. Paraphrasing he said, "The project went really well, I didn't have many problems. But I do have one question." "What is it?" "Can you explain the difference between Disk and RAM?" "..." A testament to Delphi is that someone can be productive in computer programming without understanding something fundamental like RAM and Disk.
