The unexpected lack of lectures today (Tag des Landespatrons) left time for some one-off hacks, and here are two for you:
First up is Tap Tap N950, a very basic QML prototype of what could become a funny DDR/TTR clone - no code published yet, it still need some more polishing (and touch area support for multi-touch, plus scoring is also missing).
The other one is a simple hack to make the Calendar app icon always show today's date (day-of-month). The existence of calendar icons for each day (1-31) in the theme on the device lets me suspect that this feature was either planned and then abandoned or that it will come built-in in some future firmware. For now, you can grab this lame shell script and execute it (ideally with "nohup" - see the comment inside - also needs customizations if you changed your root password, and you definitely need developer mode for now) to have an auto-updating calendar icon until the next reboot. Watch the accompanying video for a quick demo. There's now also a forum thread for support and discussion. Sometimes I really wish cron was pre-installed on Harmattan..
Bonus exercise: Store your app's .desktop file in /home/user/.local/, generate the icon dynamically via code and update the .desktop file for some icon overlay action / new items notification ;)
