• jquery multiple ajax check for all done? (order not important)

  - by second

  Is there a neat way to make sure a bunch of ajax callbacks have all finished? They don't need to be executed in order, i just need all the data to be there. one idea is to have them all increment a counter on completion and check if counter == countMax, but that seems ugly. Also, are there sync issues? (from simultaneous read/write to the counter)

• Why do I get UDP datagrams out of order even with processes runnning locally?

  - by Bilthon

  Well, I'm developing a java interface between a streaming server and a flash client. I noticed that UDP datagrams can reach my interface out of order even if both processes are running locally. Is that normal? I thought that as no datagram has to go through any router or any network device, then that should not be happening. Thanks in advance Nelson R. Perez

  - by javanix

  Suppose I have a Java method that returns a HashMap object. Because a LinkedHashMap is a subclass of HashMap, I can return a LinkedHashMap from this method just fine. On the next "read" action (no adding/removing/modifying of K/V pairs), would iterating over the keys of the resulting method (which returns a HashMap) go in the same order as the originating LinkedHashMap, even though the HashMap lacks the key links?
