How can I use interface as a C# generic type constraint?
...t. This is the default behavior of .NET. For me, this is completely unacceptable.

We need to have a constraint mechanism, so for the lack of anything better... let's use an attribute. The attribute will be present on top of a generic constraint to check if it matches our conditions...
What is the difference between RDF and OWL? [closed]
...ng the apparatus to define the components of your triple using formal computable first order description logic. That is what posters here mean by when they talk about "semantic richness".
Thirdly, it's important to realise that in OWL-Full (for OWL 1) rdfs:class and owl:class are equivalent and i...
How exactly does __attribute__((constructor)) work?
...fferently organized than .init/.fini. .ctors/.dtors sections are both just tables with pointers to functions, and the "caller" is a system-provided loop that calls each function indirectly. I.e. the loop-caller can be architecture specific, but as it's part of the system (if it exists at all i.e.) i...
How does the const constructor actually work?
... time. They are canonicalized at compile time and stored in special lookup tables (where they are hashed by their canonical signatures) from which they are later reused.
P.S.
The form #Foo#int#1#int#1 used in these samples is only used for comparison purposes and it is not a real form of canonical...

How can I pair socks from a pile efficiently?
...h I agree is the right answer. @MarkPeters I don't think you need a lookup table. A single linear pass over the socks can convert the socks to number vectors, making the mapping of "sock segment" to bucket trivial. The socks can be tied to the vectors with string so that you don't need another linea...
