In case you have missed our talks at the Qt DevDays, Nokia has put them (and a lot of other interesting) talks online now.
- View Olivier's talk on multithreading, lock-free algorithms and QMutex
(background information on lock-free programming and on QMutex in Qt5) - View Markus' talk on sockets, TCP servers and QML networking

Hope you enjoy it!
