Qt started in the mid 90's as a cross-platform framework for building native desktop applications, and gained popularity through KDE, Adobe Photoshop Elements, or Google Earth.
With embedded, mobile, web, and cloud platforms making software and software services a central part of everyone's life, Qt's cross-platform promise has taken on a completely new relevance.

In this talk, I'll show how developers can get great value out of their C++ and Qt experience, no matter which platform they target. Backend functionality for implementing web services, efficient UI creation for embedded targets, optimisation strategies when developing for micro-controllers.
