I write for About.com on C, C++ and C# programming and have been running a Programming Challenge.
You find lots of these challenges and contests on the web so I collected a list of ten that seem to be live and put them in a article Ten Programming Contests. One thing I’ve noticed is just how many Chinese and Eastern European developers are entering these. Maybe it’s a cultural thing or maybe this is where the future lies. If I do a Google Trends search for C++/C#, these are then top ten countries in order using google.
India, Pakistan, South Africa, Israel, Singapore, Viet Nam, Ukraine, Russia, Czech Republic, Denmark.
Of course maybe the richer countries like the USA, Canada, UK, France, Germany can afford the manuals and have less need to search… but interesting.
