I am using standard C and C++ commercially and actively since 1992.
Recently out of pure curiosity I have joined “Coders Rank” just to find out I am in the top 2% C++ developers, worldwide. And top 3% of C developers in London.
I might perhaps disagree with this high ranking. Last few years, the roles I am asked to take responsibility for are predominantly Architectural in nature. Still I use every free and sane moment (read: when I am not too tired) to produce a standard C or C++ related post on my (actually visited) blog.
To save you of my other “pearls of wisdom” I just present a development content from my main site .
