It's nice to write clean code (code that looks good, is organized, is easy for others to understand by reading it, etc). As developers we get to use great tools to implement algorithms in our favorite languages. The act of composing a program is much like
that of writing a story or, in some cases, a poem
But the underlying hardware isn't much interested in intelligent class hierachies and easy-to-understand lines of programming language syntax. Processors do not speak C++ or Java or C# or VB, etc.
The focus of this interview is mapping the (long and complicated)path to executable machine code that the machine natively understands and acts upon, bringing your code to life. How does this work, exactly?
Russell Hadley is a senior developer on the C++ team here at Microsoft and he spends his days (and nights, ocassionally) writing code that takes the front-end compilation linear (flattened) blob and turns it into highly optimized machine code patterns that
the processor can execute in a highly efficient manner.
This is a deep interview with lots of whiteboarding, but it is shallow enough so you won't drown if you can't swim very well. Enjoy. This is another great conversation with one of the C++ experts who live in Building 41.LOW RES FILEMP4 FILE
