In .NET 2.0 you have to code this yourself. It involves researching daylight savings time laws in various regions and building that into your own data structures.

It looks like this has been reported as a [Java bug](http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6442982). It appears to be caused by using annotations from a 3rd party library (like JUnit) and not including the jar with that annotation in the javadoc invocation.
If that is the case, just use the -classpat... |

MAC addresses in JavaScript |
|javascript| |
I know that we can get the MAC address of a user via IE (ActiveX objects).
Is there a way to do the same thing in all browsers? (Especially since FF is gaining browser share everyday!) |
I guess it depends what database you're using, but Red Gate ([www.red-gate.com][1]) make a tool called SQL Data Generator. This can be configured to fill your database with sensible looking test data. You can also tell it to always use the same seed in its random number generator so your 'random' data is the same eve... |
The quick and simple answer is No.
Javascript is quite a high level language and does not have access to this sort of information. |
If this is for an intranet application and all of the clients use DHCP, you can query the DHCP server for the MAC address for a given IP address. |
IE 8 is supposed to have better tools, but the IE Developer Toolbar is pretty good:

UDP is slightly quicker in my experience, but not by much. The choice shouldn't be made on performance but on the message content and compression techniques.
If it's a protocol with message *exchange*, I'd suggest that the very slight performance hit you take with TCP is more than worth it. You're given a connection... |
Each TCP connection requires an initial handshake before data is transmitted. Also, the TCP header contains a lot of overhead intended for different signals and message delivery detection. For a message exchange, UDP will probably suffice if a small chance of failure is acceptable. If receipt must be verified, TCP is y... |

Is Java pass by reference? |

Look into using a [numbers table][1]. While it can be hackish, it's the best method I've come by to quickly query missing data, or show all dates, or anything where you want to examine values within a range, regardless of whether all values in that range are used.
[1]: http://andre-silva-cardoso.blogspot.com/20... |
Based on the info [here][1], I'd recommend going with HashMap. I think the biggest advantage is that Java will prevent you from modifying it while you are iterating over it, unless you do it through the iterator.
