How do I pick a random element from a set? I'm particularly interested in picking a random element from a HashSet or a LinkedHashSet, in Java. Solutions for other languages are also welcome.

This is odd, ....
Clojure solution:
(defn pick-random [set] (let [sq (seq set)] (nth sq I know of.
Console.WriteLine(od[1]); Console.WriteLine(od["def"]);
In lisp
(defun pick-random (set) (nth (random (length Collections looks promising.

I am using java2d to draw a simple graph at the moment I have implemented picking by calling contains(MousePoint) for each object/shape, this works but scales linearly.
Is there a more efficient method for picking in java2d?

First of all, unless you have a lot of nodes, then linear will most likely be fine, and you shouldn't change anything unless performance is already seen to suffer .

I have a renderer using directx and openGL, and a 3d scene. The viewport and the window are of the same dimensions.
How do I implement picking given mouse coordinates x and y in a platform independent way?

Assign each object you want to pick a unique color, render the objects with these colors.
If you can, do the picking on the CPU by calculating a ray from the eye through the mouse pointer.

JXDatePicker from SwingX should meet your needs..
It is not a combobox like you said you wanted (more of a traditional calendar widget), but JCalendar by Kai Toedter works pretty well .

I'm using Visual Studio 2005. I have a program written in C#. When I create the installer and then add the primary output, it's not picking up any dependencies. Not even .Net. Anybody have any ideas?

I went back under my main project>references and removed the references... .
I fixed my own problem, but figured I would post the "fix" in case any else should run into the problem .
Try to do a build of your installer, it may add the dependencies at that time .

Also, are there tablet PCs that are powerful enough to run games?
Finally, what...

But best is "waiting" for multi-touch tablet PCs, like HP TouchSmart tx2 , and Windows7 .

For my implementation, it may be easier to divide up the bag initially into pools for one or more...

The fairest to let pick from 100% of the items still in play, hence, they should both pick from which bag they pick and [blindly,of course] pick vulnerabilities.
The end of the game, when some of players' bags are empty .
