The mSense Middleware provides a novel and powerful way to access sensor information on smartphones. A Facebook context-publishing demo showcases all the concepts present in the middleware: first, sensor information is collected from various built-in sensors like the accelerometer, magnetometer (compass) or GPS, as well as simulated sensors, user data (calendar, etc.) and input from web services like weather information. The data is then aggregated into sensor channels, which again provide an output that can be interconnected to an internal processing network. The results can then be used for various tasks or outputs, like an intertial navigation unit or to publish the user's context information to social networks like Facebook.

The middleware has been developed by Dominik Gusenbauer and Daniel Rothbauer over the course of the last 1,5 years. It's fully based on Qt for Symbian and uses the Qt Mobile Extensions to make use of the latest advanced features of today's phones. The complete source code is available for free under the GPL / Apache license.

The new Qt course will start in about two weeks in Hagenberg. The first part of the brand new materials is already available for free download.

You can expect additional modules to be added in a few weeks. Also, the corresponding exercises will be put online at a later point in time. Stay tuned and come back again soon.

Everyone who has been at the lecture about "Experiences of using Qt in Education for Mobile Computing" at the QtDevDays 2009 in Munich will know that it's a good idea to integrate Qt into the mobile curriculum. For everyone who didn't make it - the slides will also be put online at the event site in the near future.

Last but not least: don't forget to preorder the upcoming Qt for Symbian-book. My "Qt in General" chapter is a great companion to the course slides available from this site.

TagWars is a mixed reality mobile multiplayer game that uses 2D barcode tags to represent medieval villages in real life. To visit, attack or defend a village, players have to walk up to a tag and scan it.

The game has been in the queue for a long time and has now finally been released on this site. In the meantime, it has also won the mediaCUBE Games at the netdays-awards this year. Congratulations to the developers! The required server is currently not permanently running - please contact the team for more information.

A short time after the beta-release, the final Gomoku version v1.10 is now available for free through the Ovi Store and right here.

Thanks to your feedback, several small details have been improved. Especially the navigation has been optimized, the grid size is adapted to the display size, the number of captured pairs can be defined and support for German has been added.

Gomoku is fully compatible to all S60 3rd and 5th edition devices currently on the market (all touch and non-touch devices, including the N97, 5800, E71 and N95). The final release is Express Signed, so it will install on all devices without warnings. The source code of the game is available under the Eclipse Public License v1.0 and can be downloaded on the game page.

Following up on the new Forum Nokia Blogs-post by Lucian Tomuta, the ErrRd utility installation file that helps with finding out additional information about error messages on the device has been updated. Now, the tiny but helpful and quite popular tool (around 5.000 downloads up to now) also creates the c:\temp\swierrors.txt file, which enables more detailed error messages of the software installer on S60 3rd Edition, FP2+ devices. Helps finding out the real reason why installation of a .sis-file failed! For more information, also see the Wiki page on the new Symbian Foundation developer portal.
