Engadget is reporting that HP and Arizona State University's cooperation has given birth to a new prototype flexible display. Using "self-aligned imprint lithography" (SAIL) the prototype device is easy to manufacture, environmentally friendly, and incredibly resilient. Unfortunately it is still a prototype, so don't expect to see this tech hit the streets for quite a while yet.
Of course, erase() invalidates iterator. That's one of the first things you read in documentation http://www.sgi.com/tech/stl/Map.html If you don't, it's your own fault. In C++ you can write exception-safe easier than in Java, because of RAII (http://en.wikipedia.org/wiki/Resource_Acquisition_Is_Initialization) concept.
