This application allows you to find the sunrise and sunset over the world. It also shows the Analemma, the time difference between true and mean time. It shows the times either on a world view or on a time view. Nice to see that in the summer it is never dark in the summer (according to astronomers).
Nice application to play a bit with. But I am not sure who has the need for such an application.
I had a look at the MarsEdit application to see whether it would cooperate with my weblog-software (pMachine). It does not seem to be useful. I can not post (does not recognize my weblog). Can not use categories. Does not use titles. Can only use a single weblog. And I can not multiple weblogs. So this is not useful.
And I think the implementation of the pMachine Blogger API is to blaim here. So we have to wait until a better implementation comes out.
