Hoping to pass on some of the tricks I've learned and learn some new ones thereby disproving an old adage about dogs (or should that be an adage about old dogs?).
I have degrees in mathematics and computer engineering.
Professionally I use mostly C and C++ (for utilities I use Java, Perl, PHP, bash and even Prolog and LISP -- the right tool for the right job). I work a lot with big data sets and algorithmic optimization.
Recreationally I use Objective-C, C++ and C for iOS tinkering.
I have been both a programmer and manager on large projects.
