Steam devday presentation introducing debugging on Linux using Qt Creator
At the Steam developer days was a nice presentation on how to get started with debug on Linux.
Bruce Dawson, a windows developer with 20 years of experience, is presenting his experience, recommending Qt Creator his tool of choice. And he is not even working on Qt applications.
Bruce claims Qt Creator 3.0 is used in the development of Steam application, Team Fortress and other big projects inside Valve.
I went through the video quickly, looks like it's a very nice introduction to Qt Creator :)
