If it is possible, what technology makes it possible? Flash? Thank you ;)

I've got the following code: import time import threading class BaseWrapper: #static class lock = threading.Lock() @staticmethod def synchronized_def(): BaseWrapper.lock.acquire() time.sleep(5) BaseWrapper.lock.release() def test(): print time.ctime() if __name__ is '__main__': for i in xrange(10): threading.Thread(target = test).start() I want to have a method synchronized using static lock.

  • Getting shortest path between 2 nodes in quickgraph

    - by Xtapodi
    Hello, i want to ask if there is any way to generate the shortest path from node A to node B without generating the shortest paths to all the other nodes (stop when node B is in the examined set) with A-star in QuickGraph. I want to plug QuickGraph into a game and thus generating all the paths is not allowed from the time limitations the environment imposes. Any other suggestions to solve my problem in C# are welcome Thanks in advance, Xtapodi
