krupski:
I know that "boldly asserted is half proven", but I would love to see some proof (links, whatever) to back up those 3 assertions (because you are wrong on all 3 counts).
Well, he did show three example programs using the different techniques, and the version with the giant string, and the one with sprintf both used about 50% more ram, 100% more flash, and executed more slowly. What sort of proof are you looking for?
