Distributed sequence number generation?
...
OK, this is a very old question, which I'm first seeing now.
You'll need to differentiate between sequence numbers and unique IDs that are (optionally) loosely sortable by a specific criteria (typically generation time). True sequence numbers imply knowledge of what all other wor...
Can you use reflection to find the name of the currently executing method?
...

Any tips on how to organize Eclipse environment on multiple monitors?
... the IDE to both monitors (functionality even Windows 7 still lacks to my knowledge, please correct me if I am wrong) and then split the source section in half, manually making the split align with the monitor split.

...gain, note that the last one is vague; it will also be true if a is null.
Now, despite the above, the usual way to check for those is to use the fact that they're falsey:

When should I mock?
...er interface. Before we pass a mock MailServer, we "train" it, so that it knows what method calls to expect and what return values to return. At the end, the mock object asserts, that all expected methods were called as expected.
This sounds good in theory, but there are also some downsides.

Does PostgreSQL support “accent insensitive” collations?
