Off-topic but can you recommend any resources off-hand for improving in your preferred C++? I share your approach but have a heck of a time finding quality books and such. (Email in profile if preferred.)
Most often I learn code by reading code. OpenSceneGraph is an example of an open source project that has modern ish C++ but no deliberately abstract misdirection. Open source usually does not have super clean code but it's a good way to sample the variety of structures you can find in a project. Of course the classics (sqlite and the Linux kernel) are much too C-like for where I'm getting at but they are still full of lessons for how to organize modules and APIs, how many arguments to pass and where, where to park I/O code, that sort of thing.
I posted it here for the benefit of HN readers who may have the same question but I'll write you an email too so you can share what you want to improve and such. There aren't many C++ programmers left in the HN-reading, not just punching a clock demographic, and I kind of miss talking to people who get that. Like the prototypical game dev in the article I go to one conference a year, and it's not about C++.
