I have a site about programming as well, 6 years old...
before I paid real attention to adsense placement CTR was 1-1.5 %
One year ago I started to optimize and it is increased to 2-3%
removed from pages where much text, like online books, there ctr is very low, people just read page by page...
you need to use channels to see where ads work and where not... much work actually ...
