• Interesting task using random numbers only

  - by psihodelia

  Given any number of the random real numbers from the interval [0,1] is there exist any method to construct a floating point number with zero decimal part?

• Has anyone had trouble with Intellisense in Visual Studio when using UltraVNC?

  - by mullala

  Hi, a colleague and I are trying pair programming for the first time. We both remote into a development machine; I'm using RemoteDesktop and my colleague is using UltraVNC. This works great except that he can't see the Intellisense dropdown in Visual Studio 2008. According to online posts, this may be something to do with DirectDraw, but I don't see much by way of a workaround. Has anyone else experienced this? Thanks, Andrew

  - by aruwanwan

The syncing would need to reflect changes in state as well as creation of new issues.
