      Moderator, can you explain this?? :
       
      When shoot an object from north (for example from Austria) to the south to a target in the south. Earth will rotate to the left when we look northwards. So aim left, because wile the object is underway earth will keep rotating to the left.
       
      When we shoot from north where ever we on earth are, to the south to a target. Earth will keep rotating to the rigth, when we look southwards, so aim to the rigth.
       
      it has to be :

      Let's say there's this Java-driven program (ran via a batch file), which requires (1) a licence file, and (2) a protected USB key that goes along with the licence file.
      Let's now say that there are 3 types of licence files: (a) a normal licence file that gives full access to the program, if the USB key is inserted in the computer; (b) a trial licence file that does not require the USB key in order to run the program correctly, but only gives access for 600 days; and (c) a licence file that was distributed in private for a course of the program, making it available only on the day of the course, without the need for the USB key (so with this licence file, the program will always run correctly and with full functionalities, if the system date is set to 13 May 2013, course day).
      Is there a possibility to adjust/create a licence file to eventually have one licence file that allows the program to be run with full functionalities, without need for USB key and system date settings?

      Man, it is hard to get hold of an administrator here! Anyways, I have ideas for your forum!
      To attract new traffic to your site, so that more people want to advertise, you could include a new forum called 'bright sparks' or 'patents by law' or something? If you get the people posting their ideas here, like new products they want to perfect or assemble, but need help, they will all run here! This will be where you will need a simple contract written up by the court, through a lawyer, costing about a hundred dollars, where if it is posted here, it remains your property, and the rights of those posting on it, if you will?
      Then, as an aside, you would get more traffic if you had two more forums, humanities, like for psychology and culture, and language and teaching and stuff, and, one for finance, hey?
      Thanks for reading this, sorry, you seem to be the only one around at any given time...

      My cousin Jeff Stewart died this morning. Jeff was more than a cousin, he was my brother in so many ways, the way only a real brother can be. One of the few people I have ever known who was basically a good person no matter what situation he found himself in. It's difficult to wrap my head around the fact a world can exist without Jeff in it.
