I'm getting this exception every time the position changes. Anyone knows
this nucleus stuff? I don't.


Here is one backtrace:

org.datanucleus.exceptions.NucleusUserException: Found Meta-Data for class

Something as easy like here:
http://www.jqtouch.com/

Use the GeoHash function for this purpose to store LatLng in one dimension.
More info here: http://hitching.net/2009/11/10/scalable-fast-accurate-
geo-apps-using-google-app-engine-geohash-faultline-correction/

don't use a circle return all eggs inside the provided LatLng Bound which is a 
square. The square is defined by upper left and lower right point (both latlng 
values) either use latlng objects or two double pairs as parameters if not 
possible.

After finishing, re-assign this ticket to marcus.schiesser, so he updates the 
trigger of the service each time the map view changes. That way all eggs 
inside of the actual map view will be shown.

Right now the app is not a pure rich client and therefore does not run on
mobile phones if deployed as native app (via phonegap).
Make sure this works

After user presses the 'found egg' button, 
show him all tags the users before him left
and let him enter a own tag.
eggservice probably needs to be updated.

To release the app as a nice iphone webapp, the following must be done

- enhance webkit css style to look like a native app
- disable dependencies to phonegap (use navigator.geolocation instead and ask 
for iphone os 3.0 
(does not work before))
- ensure user experience is at least ok under iphone

Start with this task as soon as all other gwt frontend tasks are finished

I think you do not mean "eastern" but "easter" if there is a bunny and eggs.
Eastern stands for things that are in the east, where "easter" is the 
holiday.

- deployment to app engine
- creation of rich client javascript package that runs on file://
- packaging as android app
- packaging as iphone app

after all other issues are finished

I accidentally overwrote the marketing site at http://bunnycacher.appspot.com/ 
. Please (a) check 
the marketing site into version control or (b) fix it locally and deploy a new 
version. Preferably (a). :)

... and trying to install it afterwards results in an error on an Ubuntu
09.10 machine:

Cannot complete the install because one or more required items could
not be found.
  Software being installed: Android Development Tools
0.9.5.v200911191123-20404 (com.android.ide.eclipse.adt.feature.group
0.9.5.v200911191123-20404)
  Missing requirement: Android Development Tools
0.9.5.v200911191123-20404 (com.android.ide.eclipse.adt.feature.group
0.9.5.v200911191123-20404) requires 'org.eclipse.jdt 0.0.0' but it
could not be found"

Installing the ADT into another eclipse distribution on the same machine
works without error.

Please add a warning to the wiki page for android developers or repair the
yoxos template.

- must include game description
- must have download link for iphone/android app
- must have adsense (earning go to GTUG Karlsruhe)

after all other issues are finished

its like this for all geo apps

like the jquery thing :)

The appengine host name is not only configured in appengine.cfg.xml but
also used in Application.java for "repairing" service endpoint URLs. Maybe
make it configurable in one place.

If the user presses the 'new egg' button,
a new EI-D (unique ID) for the egg is generated and displayed to the user with 
the information to mark the egg with the EI-D.
together with this EI-D, the textbox for the hint is shown. 
if the user enters the hint,  the egg is stored as 'hidden' in the DB.
To keep the UI simple, the hint textbox serves also as tag for the first user, 
therefore inform the user that he may leave a tag together with the hint.

automatically display a hint to the egg if user is in proximity.
service probably needs to be updated too.
