Does it mean that to be a developer(any developer SQL, C# or may be Building developer) you'll need to know something that might be irrelevent? like what is the highest mountein on Mars the planet?
because someday, knowing that might help you writing a SQL procedure to calculate the distance between sun's depest crater and mars's highest tip?
The Point here is the "relevance"!
If I am really working on something specific, I'll go and look up the resources related to it. No one will ever think to come to SQLServerCentral for "which is the biggest mammel on earth?" kind of questions! its not LOGICAL! because there are hundreds of resources available on Internet to cater information related to those.
well, I really appreciate the one who posted this question because answering that question indeed added something to me which I didn't know. I am thankful too, but all our concerns is the same: "relevance"!
