The Skein hash proposed for SHA-3 boasts some impressive speed results, which I suspect would be applicable for the Threefish block cipher at its heart - but, if Skein is approved for SHA-3, would this imply that Threefish is considered secure as well...

The question however.
Putting it positively, if someone finds a weakness in Threefish then this does not imply that Skein is also insecure.
The security of Skein does not imply the security of Threefish.

If I create an HTTP java.net.URL and then call openConnection() on it, does it necessarily imply that an HTTP post is going to happen? I know that openStream() implies a GET. If so, how do you perform one of the other HTTP verbs without having to work...

This class has a setRequestMethod method to specify which HTTP method you want to use .
But if the protocol of the URL is HTTP, you'll get a HttpURLConnection as a return object .
No it does not.

Bare with me if this question is plain stupid...
When I talk to an developer from the Microsoft ASP.NET world and he uses the word "Webservice", does that word in every case imply a specific data format (XML? SOAP?)?
Or is it just anything you can call...

In particular, REST and SOAP are quite different....
In my view, it can be anything that's over http/https, and intended for calling by an application rather than a user's browser .
This is a decent overview.
The term Webservice itself is language-agnostic.

When writing a SQL statement in SQL Server 2005, does the READUNCOMMITTED query hint imply NOLOCK or do I have to specify it manually too?
So is:
With (NoLock, ReadUnCommitted)
the same as:
With (ReadUnCommitted)

The NOLOCK hint has nothing to do with the index options .
I think you can say that
ReadUnCommitted has the abilities of NoLock
However you cannot say that
NoLock has the abilities of ReadUnCommitted

Does including DISTINCT in a SELECT query imply that the resulting set should be sorted?
I don't think it does, but I'm looking for a an authoritative answer (web link).
I've got a query like this:
Select Distinct foo From Bar
In oracle, the results are...

If you want of circumstances in which a DISTINCT in Oracle does not imply a sort, the most important of which.
A sort for that calculation does not in any way imply that the result set will be sorted.

I'm writing some library code, and classes that use that code are required to have two attributes specified (one custom attribute and one from .NET).
It's a bit of a hassle to document this requirement and copy-and-paste both of those attributes onto ...

In day to day programs I wouldn't even bother thinking about the possible performance hit for coding against interfaces rather than implementations. The advantages largely outweigh the cost. So please no generic advice on good OOP.

Interfaces generally imply a few hits to performance (this however may change depending PC in the code segment.
It would imply a performance hit
The designer should be able to prove his opinion.

When you say "thin data access layer", does this mainly mean you are talking about writing your SQL manually as opposed to relying on an ORM tool to generate it for you?

That probably depends on who says it, but for me a thin data access layer would imply.

I am doing A/B testing and I am facing Simpson's paradox in my results (day vs month vs total duration of the test).

Actually, the ginal results is a weighted average for the results from each group (and on this weighting, the paradox may come up) .
The Simpson's paradox only occurs when your group sizes are different .

Is it possible to express 1 or 0 as a bit when used as a field value in a select statement?

You will have to cast each value individually.
Unfortunately, no.
Actually, that probably makes it less readable in this case .
No, but you could cast the whole expression rather than the sub-components of that expression .
